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 or proposed to be entered into by and between ESM Acquisition Corporation, a Cayman Islands exempted company (the
“Company”), and Credit Suisse Securities (USA) LLC, as the representative of the several underwriters named therein (the “Underwriters”), relating to an underwritten initial
public offering (the “Public Offering”), of 34,500,000 of the Company’s units (including up to 4,500,000 units that may be purchased to cover over-allotments, if any) (the
“Units”), each comprised of one Class A ordinary share of the Company, par value $0.0001 per share (each, an “Ordinary Share”), and
one-third of one redeemable warrant (each whole warrant, a “Warrant”). Each Warrant entitles the holder thereof to purchase one Ordinary Share at a price of $11.50 per
share, subject to adjustment. The Units shall 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 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, ESM Sponsor, LP, a Cayman Islands exempted limited partnership (the “Sponsor”),
and the other undersigned persons (each such other undersigned person, an “Insider” and collectively, the “Insiders”), each hereby agrees, severally but not jointly, with
the Company as follows: 
 1. 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 Shares owned by it, him or her in favor of any proposed Business Combination (including any proposals recommended by the
Company’s board of directors in connection with such Business Combination) and (ii) not redeem any 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. 

2. The Sponsor and each Insider hereby agrees with the Company that in the event that the Company fails to consummate a Business Combination
within 24 months from the closing of the Public Offering, or such later period approved by the Company’s shareholders in accordance with the Company’s amended and restated memorandum and articles of association,













 
as they may be amended from time to time, 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 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 (as defined below), including interest earned on the funds held in the Trust Account (less up to
$100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), divided by the number of then issued and outstanding Offering Shares, which redemption will completely extinguish all 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 each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. The Sponsor and each
Insider agrees to not propose any amendment to the Company’s amended and restated memorandum and articles of association (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the
Company’s initial Business Combination or to redeem 100% of the Offering Shares if the Company does not complete its initial Business Combination within 24 months from the closing of the Public Offering, or (ii) with respect to any other
provision 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
approval 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 funds held in the Trust Account (which interest shall be net of taxes
payable), divided by the number of then issued and outstanding Offering Shares. 
 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 the Founder Shares held by it. The Sponsor and each
Insider hereby further waives, with respect to any Shares held by it, him or her, if any, any redemption rights it, he or she may have in connection with (x) the consummation of a Business Combination, including, without limitation, any such
rights available in the context of a shareholder vote to approve such Business Combination or in the context of a tender offer made by the Company to purchase Ordinary Shares and (y) a shareholder vote to approve an amendment to the
Company’s amended and restated memorandum and articles of association (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to
redeem 100% of the Offering Shares if the Company does not complete its initial Business Combination within 24 months from the closing of the Public Offering, or (ii) with respect to any other provision 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 24 months from the date of the closing of the Public Offering).

 3. Notwithstanding the provisions set forth in paragraphs 7(a) and (b) below, 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 Credit Suisse Securities (USA) LLC, offer, sell, contract to
sell, pledge or otherwise 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
(“Section 16”) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the Commission promulgated thereunder, with
respect to, any Units, Ordinary Shares (including, but not limited to, Founder Shares), Warrants or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares owned by it, him or her, (ii) enter into any swap or other
arrangement that transfer to another, in whole or in part, any of the economic consequences of ownership to any Units, Ordinary Shares (including, but not limited to, Founder Shares), Warrants or any securities convertible into, or exercisable, or
exchangeable for, Ordinary Shares owned by it, him or her, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in
clause (i) or (ii). Each of the Insiders and the Sponsor acknowledge and agrees that, prior to the effective date of any release or waiver, of the restrictions set forth in this paragraph 3 or paragraph 7 below, the Company shall announce the
impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted shall only be effective two business days after the publication
date of such press release. The provisions of this paragraph will not apply if the release or waiver is effected solely to permit a transfer not for consideration and the transferee has agreed in writing to be bound by the same terms described in
this Letter Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer. 
 4. 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 (which for purposes of clarification shall not extend to any other
shareholders, members or managers 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 for services
rendered (other than the Company’s independent registered public accountants) or products sold to the Company or (ii) a prospective target business with which the Company has discussed entering into a transaction 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 registered public accountants) or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.00 per Offering Share or (ii) such lesser
amount per Offering Share 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, net of the amount of interest earned on the property in the Trust Account
which may be withdrawn to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as 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 Sponsor shall not be responsible to the extent of
any liability for such third party claims. The Sponsor 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
Sponsor, the Sponsor notifies the Company in writing that it shall undertake such defense.

 5. To the extent that the Underwriters do not exercise their over-allotment option to
purchase up to an additional 4,500,000 Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees that it shall forfeit, at no cost, a number of Founder Shares in the aggregate equal to
1,125,000 multiplied by a fraction, (i) the numerator of which is 4,500,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 4,500,000. All
references in this Letter Agreement to Founder Shares of the Company being forfeited shall take effect as surrenders for no consideration of such Founder Shares as a matter of Cayman Islands law. The forfeiture will be adjusted to the extent that
the over-allotment option is not exercised in full by the Underwriters so that the number of Founder Shares will equal an aggregate of 20.0% of the Company’s issued and outstanding Shares after 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 effect a capitalization, share dividend or share repurchase or redemption, as applicable, immediately prior to the consummation of the
Public Offering in such amount as to maintain the number of Founder Shares at 20.0% of the Company’s issued and outstanding Shares upon the consummation of the Public Offering. In connection with such increase or decrease in the size of the
Public Offering, then (A) the references to 4,500,000 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 Ordinary Shares included in the Units
issued in the Public Offering and (B) the reference to 1,125,000 in the formula set forth in the immediately preceding sentence shall be adjusted to such number of Founder Shares that the Sponsor would have to return to the Company in order for
the number of Founder Shares to equal an aggregate of 20.0% of the Company’s issued and outstanding Shares after the Public Offering. 

6. 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 Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 7(a), 7(b), and 9 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 seek injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event of such breach. 

7. (a) The Sponsor and each Insider agrees that it, he or she shall not Transfer (as defined below) any Founder Shares (or Ordinary Shares
issuable upon conversion thereof) until the earlier of (A) one year after the completion of the Company’s initial Business Combination and (B) subsequent to the Business Combination, (x) if the last reported sale price of the
Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share dividends, rights issuances, consolidations, reorganizations, recapitalizations and other similar transactions)
for any 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s initial Business Combination or (y) the date following the completion of the Company’s
initial Business Combination on which the Company completes a liquidation, merger, amalgamation, share exchange, reorganization or other similar transaction that results in all of the Company’s shareholders having the right to exchange their
Ordinary Shares for cash, securities or other property (the “Founder Shares Lock-up Period”). 

  
 4 













 (b) The Sponsor and each Insider agrees that it, he or she shall not Transfer any Private
Placement Warrants (or Ordinary Shares issued or issuable upon the exercise or conversion of the Private Placement Warrants), until 30 days after the completion of a Business Combination (the “Private Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”). 

(c) Notwithstanding the provisions set forth in paragraphs 7(a) and (b), transfers of the Founder Shares, Private Placement Warrants and
Ordinary Shares issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares, are permitted (a) to the Company’s directors or officers, any affiliates or family members of the Company’s
directors or officers, any members of the Sponsor or any affiliates of the Sponsor; (b) in the case of an individual, by gift to a member of the individual’s immediate family, or to a trust, the beneficiary of which is a member of the
individual’s immediate family or 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) in the case of a trust, by distribution to one or more of the permissible beneficiaries of such trust; (f) by private sales or transfers made in connection with the
consummation of the Company’s Business Combination at prices no greater than the price at which the securities were originally purchased; (g) in the event of the Company’s liquidation prior to the Company’s completion of its
initial Business Combination; (h) by virtue of the laws of the Cayman Islands or the Sponsor’s organizational documents, upon dissolution of the Sponsor; and (i) in the event of the Company’s completion of a liquidation, merger,
amalgamation, share exchange, reorganization or other similar transaction which results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property subsequent to the completion
of the Company’s initial Business Combination; provided, however, that, in the case of clauses (a) through (f), these permitted transferees must enter into a written agreement with the Company agreeing to be bound by the transfer
restrictions in this Agreement. 
 8. The Sponsor and each Insider represents and warrants that it, he or she has never been suspended or
expelled from membership in any securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked. Each Insider’s biographical information furnished to the Company, if any
(including any such information included in the Prospectus), is true and accurate in all respects and does not omit any material information with respect to such Insider’s background. Each Insider’s questionnaire furnished to the Company,
if any, is true and accurate in all respects. Each Insider represents and warrants that: it is not subject to or a respondent in any legal action for, any injunction,
cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering of securities in any jurisdiction; it has never
been convicted of, or pleaded guilty to, any crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to any dealings in any securities and it is not currently a
defendant in any such criminal proceeding. 
 9. Except as disclosed in, or as expressly contemplated by, the Prospectus, neither the Sponsor
nor any Insider nor any affiliate of the Sponsor or any Insider, nor any director or officer of the Company, shall receive from the Company any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment of a loan or other
compensation prior to, or in connection with any services rendered in order to effectuate the consummation of the Company’s initial Business Combination (regardless of the type of transaction that it is). 

  
 5

$9,400,000 depending on the extent to which the Underwriters’ overallotment option is exercised pursuant to the Underwriting Agreement), or $1.50 per Warrant, in a private placement that shall occur simultaneously with the consummation of the
