 EXHIBIT A 

TERMS AND CONDITIONS FOR SUPPLY AGREEMENT 
  


 11 NO CHANGES IN PROCESS 

Without prejudice to any of the other provisions, Seller warrants that it shall not change its feedstock, without giving Buyer reasonable notice in writing of
any such change such that Buyer can give a written response to any such change. Buyer’s response, if any, shall in no way constitute an endorsement of such change in feedstock, which shall be at Seller’s own risk. Seller shall indemnify
Buyer against all Losses arising out of any failure to give such notice. 
 12 WARRANTIES 

12.1 Seller warrants and shall ensure that: 

12.1.1 upon delivery, all Materials conform to the Specifications for such Materials specified in the Agreement; 

12.1.2 all Materials shall be supplied with all necessary documentation including any necessary guidelines or policies and shall be free
from any contamination, unauthorised ingredient or other substance and/or any manufacturing error which renders the Materials unsuitable to be used for the purpose(s) for which the Materials were designed and/or purchased; 

12.2 The warranties in clause 12.1 of these Conditions do not extend to any device, product, or system into which any Material is incorporated. The warranties
and remedies are conditional upon proper storage, installation, use and maintenance with care and good workmanship and/or in accordance with Seller’s instructions. The warranties and remedies are not applicable to any Material not used in
accordance with the currently published safety standards of the location where the Material is used. The warranties and remedies are also not applicable to, and do not cover any damage, defect, inoperability, or incorrect performance resulting from
or caused by: 
 12.2.1. any Material that has been subjected to abuse, misuse, accident, shipping or other physical damage, improper use,
abnormal operation or handling, neglect, inundation, fire, water or other liquid intrusion, negligence, or exposure to adverse environment; 

12.2.2 any Material that has been damaged due to alteration or modification by anyone not authorized by Seller; 

12.2.3 any Material which defect or problem is caused by its misuse; and 

12.2.4 any Material which has been tampered with. 

 



 12.3 Buyer is relying on Seller’s expertise and quality assurance systems to obtain Materials delivered
promptly that comply with the Agreement. Modern supply chain practices mean that deliveries are usually delivered straight into bulk storage and subsequent processes, including resale to customers with the minimum of checks. Seller was selected
partly on its ability to meet this requirement. Therefore if Seller breaches the warranty set out in clause 12.1 or otherwise fails to perform its obligations under the Agreement, Buyer shall, without prejudice to any other rights or remedies
available to Buyer and any other measures of damages, be entitled to compensation from Seller to put Buyer in the position it would have been in had Seller complied with its obligations under the Agreement, including: 

12.3.1 if required by Buyer promptly replacing the Materials in question with Materials acceptable to Buyer at no extra cost; and 

12.3.2 indemnifying Buyer for all Losses suffered by Buyer to the extent they are foreseeable at the date of the Agreement, including
disposal costs of the Materials not complying with clause 12.1, additional analytical costs, additional transport costs, disposal and replacement of contaminated bulk storage, tank cleaning costs and recall from and compensation to customers. 

12.4 Each party warrants that it and its employees, contractors and agents shall conduct themselves in such a way as to comply with the policies of the other
party relevant to the delivery of the Materials (including policies on safety health and environment, alcohol and drugs and harassment in the workplace) and acknowledge that behaviour which is incompatible with these policies may be treated by the
other party as a material breach of these Conditions. Copies of the policies of each party, as amended from time to time, are available on request. 
 12.5
If and to the extent that a party has provided or caused to be provided a container for delivery of Materials into such container, such party shall be responsible for ensuring that such container is clean and suitable prior to loading of the
Materials. Mere receipt of a tank-cleaning certificate shall not discharge the obligation of such party. 
 12.6 THE WARRANTIES PROVIDED IN THIS CLAUSE 12
ARE EXCLUSIVE AND IN LIEU OF ALL OTHER WARRANTIES, EITHER EXPRESS, IMPLIED, OR STATUTORY, REGARDING THE PRODUCTS, INCLUDING ANY WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR

losses, costs or liability arising out of or resulting from Seller’s breach of the warranty in clause 13.1. This clause 13 shall survive the termination or expiry of the Agreement howsoever arising.

 14.2 In

case Buyer shall be responsible for the acts or omissions of its contractors and Carriers. Buyer shall indemnify, protect and hold harmless Seller from Claims asserted against Seller due to the (A) acts or omissions, (B) failure to comply
with laws or governmental regulations, or (C) failure to comply with the requirements and procedures of a Facility, by Buyer’s contractors or Carriers. 

14.3 This agreement to indemnify the other party shall not be negated or reduced by virtue of the denial of insurance coverage by parties or Carrier’s
insurers of the occurrence or event which is the subject matter of the claims, and/or refusal to defend the insured party. The other party shall have the right, but not the duty, to participate in the defense of any claim or litigation with
attorneys of its own selection.

provided with accurate and compliant safety data sheets. 
 24.2 During the Demo Phase, the Buyer guarantees that Buyer’

any law, rules, order or action of any court or instrumentality of the federal or any state government, or for any other cause or causes beyond its reasonable control, it is agreed that upon such party’s giving notice and full particulars of
such force majeure to the other party, the obligations of the party giving such notice shall be suspended from the date of the other party’s receipt of such notice and for the continuance of any inability so caused, but for no longer period,
and such cause shall, so far as possible, be remedied with all reasonable dispatch. The term “force majeure” shall not apply to those events merely making it more difficult or costly for either party to perform their obligations under the
Agreement. It is further agreed that at the conclusion of any force majeure event, neither party shall have any obligation to the other with respect to any quantities of Materials not delivered as a consequence of such force majeure event. No
condition of force majeure shall operate to extend the terms of the Agreement.

procedures of Seller, and (c) any other applicable requirements of whatever nature in force at the Facility. It shall be the absolute responsibility of Buyer and each Carrier to fully understand, and comply with, the requirements of the
Facility current at all times this Agreement is in effect. Notwithstanding anything to the contrary express or implied in the Agreement, if any Carrier nominated by the Buyer does not comply with the foregoing provisions or any of them, Seller may
refuse to connect or load the Carrier in question. Buyer shall cause its Carriers who will be accessing the Facility in connection with this Agreement to carry and maintain, at its sole expense, with reliable insurance companies acceptable to Seller
and authorized to do business in the state or area in which the Facility is located, at least the minimum insurance coverage as required by each party in clause 19.
