COOPERATION LETTER AGREEMENT

This Cooperation Letter Agreement (“Letter Amendment”) is made and entered into this 2nd of October 2022 by and between LanzaTech, Inc., a company organized and existing under the laws of Delaware (“LanzaTech”), Suncor Energy Inc. a corporation existing under the laws of Canada (“Suncor”) and BGTF LT Aggregator LP, a limited partnership registered in Delaware (“Brookfield”). Each of LanzaTech, Suncor and Brookfield shall be referred to herein, individually, as a “Party,” and, collectively, as the “Parties”.

RECITALS

WHEREAS, LanzaTech and Suncor are party to a Master Licensing Agreement dated October 6, 2020 pursuant to which LanzaTech grants to Suncor certain commercial rights relating to LanzaTech’s technology and business (“Master Licensing Agreement”).

WHEREAS, LanzaTech and Brookfield are party to a Framework Agreement dated the date of this Letter Agreement pursuant to which LanzaTech grants to Brookfield certain rights relating to projects that deploy LanzaTech’s technology (“Framework Agreement”).

WHEREAS, LanzaTech and Suncor have agreed to enter into an amendment to the Master Licensing Agreement dated on or about the date of this Letter Agreement pursuant to which Suncor’s commercial rights relating to LanzaTech’s technology are amended in order to implement Brookfield’s rights relating to projects that deploy LanzaTech’s technology under the Framework Agreement.

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

AGREEMENT

Article 1

Definitions and Interpretation

1.1

The Parties acknowledge that under the Master Licensing Agreement, LanzaTech has granted to Suncor a right of first refusal with respect to any project investment opportunity that is to be offered to or by LanzaTech from or to a party other than LanzaTech or Suncor in respect of certain LanzaTech projects.

1.2	The Parties acknowledge that under the Framework Agreement, LanzaTech has granted to Brookfield certain rights to invest in certain projects that deploy LanzaTech technology.

Article 2

First Right of Refusal to certain Suncor Projects

2.1	The Parties hereby agree the following:

(a)

Where, in accordance with the terms of the Framework Agreement, LanzaTech notifies Brookfield of an equity investment opportunity for a project in Canada and/or the State of Colorado pursuant to an FID Notice (as defined in the Framework Agreement, which in general terms is notice that the project is construction-ready), LanzaTech will, at the latest, simultaneously notify Suncor of the existence of the relevant project investment opportunity.

(b)

Where, in accordance with the terms of, and pursuant to, the Framework Agreement, Brookfield or its designee pursues after receipt of an FID Notice (as defined in the Framework Agreement) an equity investment opportunity in respect of a construction-ready project in Canada and/or the State of Colorado that uses LanzaTech Licensed Subject Matter (as defined in the Master Licensing Agreement), Brookfield hereby grants to Suncor the right, exercisable at Suncor’s sole discretion, to invest in such project in an amount up to [***] of the required equity capital for such project on terms to be proposed by Brookfield and agreed at the time, but that will in no event be less favorable on a per share or equivalent economic unit basis in any material respect than those of other equity capital investors (including Brookfield) in such project; provided, that governance and other non-economic terms shall be commercially reasonable but otherwise determined by Brookfield in good faith. Brookfield shall notify Suncor in writing of the terms of the offer (the “Suncor FID Notice”). Suncor shall have [***] from the receipt of such Suncor FID Notice to agree to invest in such project on the terms set out in such Suncor FID Notice. Where Suncor does not agree to invest on such terms or does not respond to the Suncor FID Notice within [***] of receipt, then Brookfield or its designee may either (i) invest one hundred percent (100%) of the equity capital in such project itself (including with its affiliates) or (ii) enter into an agreement with one or more parties for the required equity capital for such project on terms that are either consistent on a per share or equivalent economic unit basis in all material respects to the terms in the Suncor FID Notice (or any subsequent offer to Suncor) or less favorable on a per share or equivalent economic unit basis to the investor than those offered to Suncor in the Suncor FID Notice (or any subsequent offer to Suncor) (as reasonably determined by Brookfield in good faith).

Suncor projects

(c)

Where Suncor establishes a project that uses LanzaTech Licensed Subject Matter that in Suncor’s complete discretion requires equity capital from a party other than Suncor and its affiliates, Suncor hereby agrees to:

(i)

notify Brookfield of such investment opportunity (“Suncor Project Notice”); and

(ii)

consider any investment proposal that Brookfield presents within [***] and prior to execution of any final agreements with any third parties,

provided that Suncor is under no obligation to delay ongoing negotiations during this period, or accept any investment proposal provided by Brookfield or, after compliance with Article 2.1(c)(ii), delay the execution of any agreement(s).
