Corp. II, a Delaware corporation (“Acquiror”), (iii) LanzaTech NZ, Inc., a Delaware corporation (the “Company”),
and (iv) the Persons identified on Schedule I attached to the Agreement (as defined below) (together with the Sponsor, the “Insider
Holders”). Acquiror, the Insider Holders and the Company are sometimes collectively referred to herein as the “Parties”,
and each of them is sometimes individually referred to herein as a “Party”.

 

WHEREAS, the Parties
have entered into that certain Sponsor Support Agreement, dated as of March 8, 2022 (the “Agreement”); and

 

WHEREAS, the Parties
desire to amend certain provisions of the Agreement.

 

NOW, THEREFORE, in
consideration of the foregoing and the representations, warranties, covenants and agreements set forth in this Agreement, the Parties,
intending to be legally bound, agree as follows:

 

1.                 
Capitalized terms used in this Amendment but not otherwise defined herein have the meanings ascribed thereto in the Agreement,
and this Amendment shall be governed by the provisions of Sections 3.1 and 3.2 of the Agreement, mutatis mutandis (and in each
case as the same are modified or amended in this Amendment).

 

2.                 
The definition of “Forfeited Promote Shares” in Section 3.1 of the Agreement is hereby amended and restated in its
entirety to read as follows:

 

“Forfeited
Promote Shares” means a number of the Promote Shares equal to: (i) the product of (A) one third (1/3) of the Promote Shares
multiplied by (B) a percentage equal to the product of (I) the Redemption Percentage minus 50% multiplied by (II) two (2); minus (ii)
the aggregate number of Promote Shares subject to Transfer to holders of Acquiror Class A Shares pursuant to the Non-Redemption Agreements;
provided that the number of Promote Shares counted in the foregoing clause (ii) shall not exceed 1,250,000 in the aggregate. An
illustrative example setting forth the calculation of the Forfeited Promote Shares (assuming that no Promote Shares are subject to Transfer
to holders of Acquiror Class A Shares pursuant to the Non-Redemption Agreements) is set forth on Exhibit A attached hereto.

 

3.                 
Except as expressly amended hereby, the Agreement is not amended, modified or affected by this Amendment, and the Agreement, and
the rights and obligations of the Parties thereunder, remain in full force and effect in all respects.

 

     

     

    

 

4.                 
 In the event of any conflict between the terms of this Amendment and the terms of the Agreement, the terms of this Amendment shall
prevail. Upon the effectiveness of this Amendment, each reference in the Agreement to “this Agreement,” “hereunder,”
 “hereof,” “herein,” or words of like import shall mean and be a reference to the Agreement as amended hereby,
and each reference to the Agreement in any other document, instrument or agreement executed or delivered in connection with the Agreement
shall mean and be a reference to the Agreement as amended hereby.

 

5.                 
This Amendment, and all claims or causes of action based upon, arising out of, or related to this Amendment (whether based on contract,
tort, equity or otherwise), shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without giving
effect to principles or rules of conflict of Laws (whether of the State of Delaware or of any other jurisdiction) to the extent such principles
or rules would require or permit the application of Laws of a jurisdiction other than the State of Delaware.

 

6.                 
Any Action based upon, arising out of or related to this Amendment shall be finally resolved pursuant to Section 3.9 of the Agreement,
which is hereby incorporated by reference and shall apply to this Amendment as if set forth herein in its entirety, mutatis mutandis.

 

7.                 
This Amendment may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together
shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Amendment by facsimile,

WHEREAS, the Company and Subscriber entered into
that certain Subscription Agreement, dated as of March 8, 2022 (the “Subscription Agreement”), pursuant to which Subscriber
agreed to subscribe for and purchase from the Company, and the Company agreed to issue and sell to Subscriber, that number of shares of
the Company’s Class A common stock, par value $0.0001 per share (the “Class A Common Stock”), set forth on the
signature page thereto (the “Subscribed Shares”), for a purchase price of $10.00 per share (the “Per Share
Price” and the aggregate of such Per Share Price for all Subscribed Shares being referred to herein as the “Purchase
Price”);

 

WHEREAS, on March 8, 2022, the Company entered
into a definitive agreement with LanzaTech NZ, Inc., a Delaware corporation (“LanzaTech”), and the other parties thereto,
providing for a business combination between the Company and LanzaTech (the “Merger Agreement” and the transactions
contemplated by the Merger Agreement, the “Transaction”);

 

WHEREAS, the Company desires to amend the Merger
Agreement in the form attached hereto as Annex A (the “Merger Agreement Amendment”) and, pursuant to Section
2(e) of the Subscription Agreement, the consent of Subscriber in writing is required in order to amend certain provisions of the Merger
Agreement; and

 

WHEREAS, the Company and Subscriber desire to
amend the Subscription Agreement in order to align its terms with the proposed amendment to the Merger Agreement.

 

NOW, THEREFORE, in consideration of the foregoing
and the mutual representations, warranties and covenants, and subject to the conditions, herein contained, and intending to be legally
bound hereby, the Company and Subscriber hereto hereby agree as follows:

 

1.                  
Capitalized terms used in this Amendment and Consent but not otherwise defined herein have the meanings ascribed thereto in the
Subscription Agreement.

 

2.                  
Subscriber hereby consents, for all purposes under the Subscription Agreement, to the Merger Agreement Amendment, in the form attached
hereto as Annex A.

 

3.                  
Effective as of the effective date of the Merger Agreement Amendment, the first recital of the Subscription Agreement shall be
amended to include the words “as amended, amended and restated or supplemented from time to time” immediately before the words
 “the ‘Merger Agreement’”.

 

4.                  
Effective as of the effective date of the Merger Agreement Amendment, Section 6 of the Subscription Agreement shall be amended
to replace “December 7, 2022” with “February 28, 2023”.

 

5.                  
Except as expressly amended hereby, the Subscription Agreement shall not be amended, modified or affected by this Amendment and
Consent, and the Subscription Agreement, and the rights and obligations of the Company and Subscriber thereunder, shall remain in full

6.                   In
the event of any conflict between the terms of this Amendment and Consent and the terms of the Subscription Agreement, the terms of
this Amendment and Consent shall prevail. Upon the effectiveness of this Amendment and Consent, each reference in the Subscription
Agreement to “this Agreement,” “hereunder,” “hereof,” “herein,” or words of like
import shall mean and be a reference to the Subscription Agreement as amended hereby, and each reference to the Subscription
Agreement in any other document, instrument or agreement executed or delivered in connection with the Subscription Agreement shall
mean and be a reference to the Subscription Agreement as amended hereby.

 

7.                  
This Amendment and Consent shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard
to the principles of conflicts of laws that would otherwise require the application of the laws of any other state.

 

8.                  
Any Action based upon, arising out of or related to this Amendment and Consent shall be finally resolved pursuant to Sections 8(q)-(r)
of the Subscription Agreement, which are hereby incorporated by reference and shall apply to this Amendment and Consent as if set forth
herein in their entirety, mutatis mutandis.

 

9.                  
This Amendment and Consent may be executed and delivered in one or more counterparts (including by electronic mail, in .pdf or
