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 among AMCI Acquisition Corp. II, a Delaware corporation (the “Company”), and Evercore
Group L.L.C., as representative (the “Representative”) of the several underwriters (each, an “Underwriter”
and collectively, the “Underwriters”), relating to an underwritten initial public offering (the “Public
Offering”), of up to 17,250,000 of the Company’s units (including up to 2,250,000 units that may be purchased
to cover over-allotments, if any) (the “Units”), each comprised of one share of the Company’s Class A
common stock, par value $0.0001 per share (the “Class A Common Stock”), and one-half of one redeemable
warrant. Each whole warrant (each, a “Warrant”) entitles the holder thereof to purchase one share of Class A
Common Stock 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 Nasdaq Capital 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, each of AMCI Sponsor II LLC (the “Sponsor”)
and the undersigned individuals, each of whom is 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.            The
Sponsor and each Insider agrees that if the Company seeks stockholder approval of a proposed Business Combination, then in connection
with such proposed Business Combination, it, he or she shall (i) vote any shares of Common Stock (as defined below) owned by it,
him or her in favor of any proposed Business Combination and (ii) not redeem any shares of Common Stock owned by it, him or her in
connection with such stockholder 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 shares of Common Stock owned by it, him or her
in connection therewith.


 


2.            The
Sponsor and each Insider hereby agrees 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 stockholders in accordance with the Company’s
amended and restated certificate of incorporation (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 business days thereafter, redeem 100% of the shares
of Class A Common Stock 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 (which interest shall be net of taxes payable and up to $100,000 of interest to
pay dissolution expenses), divided by the number of then outstanding Offering Shares, which redemption will completely extinguish all
Public Stockholders’ (as defined below) rights as stockholders (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
stockholders and the Company’s board of directors, liquidate and dissolve, subject in each case to the Company’s obligations
under Delaware law to provide for claims of creditors and other requirements of applicable law. The Sponsor and each Insider agrees to
not propose any amendment to the Charter to modify the substance or timing of the Company’s obligation to redeem 100% of the Offering
Shares if the Company does not complete a Business Combination within the required time period set forth in the Charter or with respect
to any other material provisions relating to stockholders’ rights or pre-initial business combination activity, unless the Company
provides its Public Stockholders 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 and not previously released to the Company to pay its taxes, divided by the number of then 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, him or her. The
Sponsor and each Insider hereby further waives, with respect to any shares of Common Stock held by it, him or her, if any, any redemption
rights it, he or she may have in connection with (A) the consummation of a Business Combination, including, without limitation, any
such rights available in the context of a stockholder vote to approve such Business Combination, or (B) a stockholder vote to approve
an amendment to the Charter to modify the substance or timing of the Company’s obligation 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 with respect to any other
material provisions relating to stockholders’ rights or pre-initial business combination activity or in the context of a tender
offer made by the Company to purchase Offering Shares (although the Sponsor, the Insiders and their respective affiliates 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).


 


3.            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, (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 (the “Exchange Act”), and the rules and regulations of the Commission
promulgated thereunder, with respect to, any Units, shares of Common Stock (including, but not limited to, Founder Shares), Warrants or
any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her, (ii) enter
into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any
Units, shares of Common Stock (including, but not limited to, Founder Shares), Warrants or any securities convertible into, or exercisable,
or exchangeable for, shares of Common Stock 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).


 


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 (the “Indemnitor”) 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 or (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”); 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, less taxes payable,
(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. 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.

5.            To
the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 2,250,000 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 in the aggregate equal to 562,500 multiplied by a fraction, (i) the numerator of which is 2,250,000 minus the number
of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 2,250,000.
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 an aggregate of 20.0% of the Company’s issued and outstanding shares of Class A Common Stock
after the Public Offering (not including shares of Class A Common Stock underlying the Warrants or Private Placement Warrants (as
defined below)). The Sponsor further agrees that to the extent that the size of the Public Offering is increased or decreased, the Company
will purchase or sell Units 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 ownership of the initial shareholders prior to the Public Offering at 20.0% of
its issued and outstanding Capital 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 2,250,000 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 Public Shares included in the Units issued in the
Public Offering and (B) the reference to 562,500 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 initial shareholders to hold
an aggregate of 20.0% of the Company’s issued and outstanding shares of Class A Common Stock after the Public Offering (not
including shares of Class A Common Stock underlying the Warrants or Private Placement Warrants).


 


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 an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 7(a), and 7(b), 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.


 


7.            (a) The
Sponsor and each Insider agrees that it, he or she shall not Transfer any Founder Shares (or any shares of Class A Common Stock 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 closing price of the Class A Common Stock equals or exceeds
$12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) 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
on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results
in all of the Company’s stockholders having the right to exchange their shares of Class A Common Stock for cash, securities
or other property (the “Founder Shares Lock-up Period”).


 






    3


     


    

 


(b)            The
Sponsor and each Insider agrees that it, he or she shall not Transfer any Private Placement Warrants (or any share of Class A Common
Stock issued or issuable upon the exercise 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 shares of Class A
Common Stock issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares that are held
by the Sponsor, any Insider or any of their permitted transferees (that have complied with this paragraph 7(c)), 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 Sponsor or to any members of the Sponsor or any of their affiliates; (b) in the case of an individual, by gift to a member
of such individual’s immediate family or to a trust, the beneficiary of which is a member of such individual’s immediate family,
an affiliate of such individual or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and
distribution upon death of such 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 any forward purchase agreement or similar arrangement or in connection with the consummation
of an initial Business Combination at prices no greater than the price at which the securities were originally purchased; (f) in
the event of the Company’s liquidation prior to the completion of an initial Business Combination; (g) by virtue of the laws
of the State of Delaware or the Sponsor’s limited liability company agreement upon dissolution of the Sponsor; or (h) in the
event of the Company’s liquidation, merger, capital stock exchange or other similar transaction which results in all of the Company’s
stockholders having the right to exchange their shares of Class A Common Stock for cash, securities or other property subsequent
to the Company’s completion of an initial Business Combination; provided, however, that in the case of clauses (a) through
(e) or (g), these permitted transferees must enter into a written agreement with the Company agreeing to be bound by the transfer
restrictions herein and the other restrictions contained in this Agreement (including provisions relating to voting, the Trust Account
and liquidating distributions).


 


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 (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 the Insider’s background. The Sponsor and each Insider’s
questionnaire furnished to the Company is true and accurate in all respects. The Sponsor and each Insider represents and warrants that:
it, he or she 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, he or she 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, he or she is not currently a defendant in
any such criminal proceeding.


 


9.            Except
as disclosed in the Prospectus, neither the Sponsor nor any officer, nor any affiliate of the Sponsor or any officer, nor any director
of the Company, shall receive from the Company any finder’s fee, reimbursement, consulting fee, non-cash payments, 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), other than the following, none
of which will be made from the proceeds held in the Trust Account prior to the completion of the initial Business Combination: repayment
of a loan and advances up to an aggregate of $300,000 made to the Company by the Sponsor; payments to the Sponsor for certain office space,
secretarial and administrative services as may be reasonably required by the Company of $10,000 per month; reimbursement for any reasonable
out-of-pocket expenses related to identifying, investigating, negotiating and completing an initial Business Combination, and repayment
of loans, if any, and on such terms as to be determined by the Company from time to time, made by the Sponsor or an affiliate of the Sponsor
or any of the Company’s officers or directors to finance transaction costs in connection with an intended initial Business Combination,
provided, that, if the Company does not consummate an initial Business Combination, a portion of the working capital held outside the
Trust Account may be used by the Company to repay such loaned amounts so long as no proceeds from the Trust Account are used for such
repayment. Up to $1,500,000 of such loans may be convertible into warrants at a price of $1.00 per warrant at the option of the lender.
Such warrants would be identical to the Private Placement Warrants, including as to exercise price, exercisability and exercise period.

to serve as an officer and/or director on the board of directors of the Company and hereby consents to being named in the Prospectus as

14.            No
party hereto may assign either this Letter Agreement or any of its rights, interests, or obligations hereunder without the prior written
