this “Agreement”), is entered into by and among AMCI Acquisition Corp. II, a Delaware corporation (the “Company”),
and AMCI Sponsor II LLC, a Delaware limited liability company (the “Purchaser”).

of one redeemable warrant. Each whole warrant entitles the holder to purchase one Share at an exercise price of $11.50 per Share. The
Purchaser has agreed to purchase an aggregate of 3,500,000 warrants (or 3,725,000 warrants in the aggregate to the extent the over-allotment
option in connection with the Public Offering is exercised) (the “Private Placement Warrants”), each Private Placement
Warrant entitling the holder to purchase one Share at an exercise price of $11.50 per Share.


 


NOW THEREFORE, in consideration
of the mutual promises contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties to this Agreement hereby, intending legally to be bound, agree as follows:

C.            Investment
Representations.


 


(i)            The
Purchaser is acquiring the Private Placement Warrants and, upon exercise of the Private Placement Warrants, the Shares issuable upon such
exercise (collectively, the “Securities”), for the Purchaser’s own account, for investment purposes only and
not with a view towards, or for resale in connection with, any public sale or distribution thereof.


 


(ii)           The
Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D of the Securities
Act of 1933, as amended (the “Securities Act”), and the Purchaser has not experienced a disqualifying event as enumerated
pursuant to Rule 506(d) of Regulation D under the Securities Act.


 


(iii)          The
Purchaser understands that the Securities are being offered and will be sold to it in reliance on specific exemptions from the registration
requirements of the United States federal and state securities laws and that the Company is relying upon the truth and accuracy of, and
the Purchaser’s compliance with, the representations and warranties of the Purchaser set forth herein in order to determine the

(iv)          The
Purchaser did not decide to enter into this Agreement as a result of any general solicitation or general advertising within the meaning
of Rule 502(c) under the Securities Act.


 


(v)           The
Purchaser has been furnished with all materials relating to the business, finances and operations of the Company and materials relating
to the offer and sale of the Securities which have been requested by the Purchaser. The Purchaser has been afforded the opportunity to
ask questions of the executive officers and directors of the Company. The Purchaser understands that its investment in the Securities
involves a high degree of risk and it has sought such accounting, legal and tax advice as it has considered necessary to make an informed
investment decision with respect to the acquisition of the Securities.


 


(vi)          The
Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made
any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities by the Purchaser
nor have such authorities passed upon or endorsed the merits of the offering of the Securities.


 


(vii)         The
Purchaser understands that: (a) the Securities have not been and are not being registered under the Securities Act or any state securities
laws, and may not be offered for sale, sold, assigned or transferred unless (1) subsequently registered thereunder or (2) sold
in reliance on an exemption therefrom; and (b) except as specifically set forth in the Registration Rights Agreement, neither the
Company nor any other person is under any obligation to register the Securities under the Securities Act or any state securities laws
or to comply with the terms and conditions of any exemption thereunder. While the Purchaser understands that Rule 144 under the Securities
Act is not available for the resale of securities initially issued by shell companies (other than business combination related shell companies)
or issuers that have been at any time previously a shell company, the Purchaser understands that Rule 144 includes an exception to
this prohibition if the following conditions are met: (i) the issuer of the securities that was formerly a shell company has ceased
to be a shell company; (ii) the issuer of the securities is subject to the reporting requirements of Section 13 or 15(d) of
the Securities Exchange Act of 1934, as amended (the “Exchange Act”); (iii) the issuer of the securities has filed
all Exchange Act reports and material required to be filed, as applicable, during the preceding 12 months (or such shorter period that
the issuer was required to file such reports and materials), other than Form 8-K reports; and (iv) at least one year has elapsed
from the time that the issuer filed current Form 10 type information with the SEC reflecting its status as an entity that is not
a shell company.


 


(viii)        The
Purchaser has knowledge and experience in financial and business matters, understands the high degree of risk associated with investments
in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment
in the Securities and is able to bear the economic risk of an investment in the Securities in the amount contemplated hereunder for an
indefinite period of time. The Purchaser has adequate means of providing for its current financial needs and contingencies and will have
no current or anticipated future needs for liquidity which would be jeopardized by the investment in the Securities. The Purchaser can
afford a complete loss of its investment in the Securities.
