and each of the parties set forth on the signature page hereto under “Purchasers” (the “Purchasers”).


 


WHEREAS:


 


The
Company intends to consummate an initial public offering of the Company’s units (the “Public Offering”),
each unit consisting of one share of the Company’s Class A common stock, par value $0.0001 per share (each, a “Share”),
and one-third of one warrant as set forth in the Company’s registration statement on Form S-1, filed with the Securities

under the Securities Act of 1933, as amended (the “Securities Act”);


 


Each
whole warrant entitles the holder to purchase one Share at an exercise price of $11.50 per Share; and


 


The
Purchasers have agreed to purchase an aggregate of 5,333,333 warrants (or up to 5,933,333 warrants if the over-allotment option
in connection with the Public Offering is exercised in full) (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,

Warrants to the Purchasers.


 






     


     


    

 


B.
Purchase and Sale of the Private Placement Warrants. On the date that is one business day prior to the date of the consummation
of the Public Offering or on such earlier time and date as may be mutually agreed by the Purchasers and the Company (the “Initial
Closing Date”), the Company shall issue and sell to the Purchasers, and the Purchasers shall purchase from the Company
the Private Placement Warrants set forth opposite such Purchaser’s name on Exhibit A to this Agreement at a price of $1.50
per warrant for an aggregate purchase price of approximately $8,000,000 (the “Purchase Price”), which shall
be paid by wire transfer of immediately available funds to the Company in accordance with the Company’s wiring instructions.
On the Initial Closing Date, upon the payment by the Purchasers of the Purchase Price set forth opposite such Purchaser’s
name on Exhibit A to this Agreement by wire transfer of immediately available funds to the Company, the Company shall, at its
option, deliver a certificate evidencing the Private Placement Warrants purchased on such date duly registered in such Purchaser’s
name to each Purchaser, or effect such delivery in book-entry form. On the date that is one business day prior to each date of
the consummation of the closing of the over-allotment option in connection with the Public Offering or on such earlier time and
date as may be mutually agreed by Decarbonization Plus Acquisition Sponsor, LLC, a Delaware limited liability company (the “Sponsor”),
and the Company (each such date, an “Over-allotment Closing Date,” and each Over-allotment Closing Date (if
any) and the Initial Closing Date being sometimes referred to herein as a “Closing Date”), the Company shall
issue and sell to the Sponsor, and the Sponsor shall purchase from the Company, up to an aggregate of 600,000 Private Placement
Warrants at a price of $1.50 per warrant for an aggregate purchase price of up to $900,000 (if the over-allotment option in connection
with the Public Offering is exercised in full) (the “Over-allotment Purchase Price”), which shall be paid by
wire transfer of immediately available funds to the Company in accordance with the Company’s wiring instructions. On the
Over-allotment Closing Date, upon the payment by the Sponsor of the Over-allotment Purchase Price by wire transfer of immediately
available funds to the Company, the Company shall, at its option, deliver a certificate evidencing the Private Placement Warrants
purchased on such date duly registered in the Sponsor’s name to the Sponsor, or effect such delivery in book-entry form.

(i)
Each Private Placement Warrant shall have the terms set forth in a Warrant Agreement to be entered into by the Company and a warrant
agent, in connection with the Public Offering (the “Warrant Agreement”).


 


(ii)
At the time of the closing of the Public Offering, the Company and the Purchasers shall enter into a registration rights agreement
(the “Registration Rights Agreement”) pursuant to which the Company will grant certain registration rights
to the Purchasers relating to the Private Placement Warrants and the Shares underlying the Private Placement Warrants.

C.
Investment Representations.


 


(i)
Such 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 such 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)
Such Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D under the Securities
Act.


 


(iii)
Such 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 such Purchaser’s compliance with, the representations and warranties of such Purchaser set forth
herein in order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire such Securities.

the meaning of Rule 502(c) of Regulation D under the Securities Act.

relating to the offer and sale of the Securities which have been requested by such Purchaser. Such Purchaser has been afforded
the opportunity to ask questions of the executive officers and directors of the Company. Such Purchaser understands that its investment

    4


     


    

 


(vi)
Such Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed

by such Purchaser nor have such authorities passed upon or endorsed the merits of the offering of the Securities.


 


(vii)
Such 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; (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; and (c) Rule 144 adopted pursuant to the
Securities Act will not be available for resale transactions of Securities prior to a Business Combination and may not be available
for resale transactions of Securities after a Business Combination.


 


(viii)
Such Purchaser has such knowledge and experience in financial and business matters, knows of 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. Such Purchaser has adequate means of providing for such Purchaser’s
current financial needs and contingencies and will have no current or anticipated future needs for liquidity which would be jeopardized
