Re: Letter of Agreement between LanzaTech, Inc. (“LanzaTech”) and Indian Oil Corporation Limited (“IndianOil”) for deployment of LanzaTech technology

This Letter of Agreement (“Agreement”) is executed by LanzaTech’ and IndianOil. LanzaTech and IndianOil may hereinafter collectively be referred to as “Parties” and individually as “Party”.

This Agreement is executed in consideration of the License Agreement of even date entered into between LanzaTech as ‘Licensor’, and IndianOil as ‘Licensee’ in respect of LanzaTech’s gas fermentation technology (“LanzaTech Process”), specifically to produce ethanol from [***] at the hydrogen plant at IndianOil’s Panipat refinery in Haryana (“Licensed Process”).

LanzaTech and IndianOil agree and acknowledge that the LanzaTech Process has been demonstrated [***] at [***] in Shanghai, China and certain other demonstration facilities, and that the plant intended to be set up by IndianOil to implement the Licensed Process (“First Unit”) will be the first of its kind at that scale.

Accordingly, the successful commissioning of the First Unit holds significant business and commercial interests for LanzaTech and IndianOil.

LanzaTech wishes to record that as of the date of this Agreement the Licensed Process has not been demonstrated at the scale of the First Unit and as a result LanzaTech has offered terms, including royalty and technology cut-off date as set out in this Agreement in recognition of the risks adopted by IndianOil in deploying the Licensed Process at the First Unit on the anticipated timeframe.

LanzaTech and IndianOil agree as below;

1.	First Unit and Future Units.

1.1.	IndianOil shall participate in the BEDP for the First Unit, and LanzaTech shall undertake the BEDP, make available propriety process control and propriety microbes and trace media mix further to the License Agreement.

1.2.

LanzaTech shall grant license with respect to the Licensed Process, make available propriety process control and propriety microbes and trace media mix, and IndianOil shall undertake the Basic Engineering and Design Package (“BEDP”) for Future Units (i.e. units that follow the First Unit) (“Future Units”) based on the Licensed Process in respect of which Definitive Agreements are entered during the term of this Agreement. The Future Units, may be:

IndianOil Future Units, i.e. units set up by IndianOil and or its Affiliate (the expression ‘Affiliate’ shall have the same meaning as defined in the License Agreement), using the Licensed Process (“IndianOil Future Units”);

ii.

Third Party Future Units, i.e. units set up by persons other than IndianOil and or its Affiliate, using the Licensed Process (“Third Party Future Units”).

1.3.	Certain business terms in respect of agreement under Paragraph No. 1.1 and 1.2 above, are set forth in Exhibit A.

1.4.

LanzaTech and IndianOil agree that they shall enter into definitive separate agreement with respect to each Future Unit (“Definitive Agreements”), whether for the preparation of BEDP and or license to use the Licensed Process, as the case may be, only at which point any obligation on the Parties relating to the BEDP or license will become legally binding.

Confidentiality. This Agreement, the matters discussed herein and information provided by one Party to the other in connection herewith (collectively, “Information”) are confidential and shall not be disclosed by the receiving Party without the written consent of the other, except to the extent that disclosure.is required by law.
