|-- | ------------------------------



|2.1 | It is the intention of both parties to this Agreement that the supply of Product under this Agreement will be sufficient to meet the needs of PURCHASER for the Product
in Wesseling. PURCHASER acknowledges that if and to the extent that its demand for 1,3-Butadiene is in excess of the existing 1,3-Butadiene consumption of the present Elastomers production facilities of ELENAC, then this increased demand can be met
by DSC only following the giving of an adequate period of advanced notice to DSC, such notice period to be determined by DSC, so as to enable DSC to terminate in accordance any binding obligations, which DSC may have to make deliveries to other
customers, thereby making available sufficient 1,3-Butadiene quantities for the supply to PURCHASER to the increased demand of PURCHASER.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.2 | Notwithstanding the provisions of sub-clause 2.1 DSC shall supply to PURCHASER up to 47,000 Tonnes of Product per Year, and PURCHASER shall purchase at least 30,000
Tonnes of Product per Year.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.3 | The obligation of PURCHASER to take delivery of Product may be taken over wholly or in part by one or more of those of its Affiliates listed in Attachment III. In the
event that an Affiliate of PURCHASER takes delivery of Product at a location other than Wesseling the price as set out in clause 7 will be fob Wesseling.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.4 | In the event that ELENACs 1,3-Butadiene plant does not have sufficient Product available to supply to PURCHASER, DSC has the right to supply Product from other
sources provided that such Product complies with the Specifications set out in Attachment I hereto, subject to agreement of terms and conditions for the supply of those volumes between PURCHASER and DSC. DSC will only start to supply Product from
any other source following receipt of approval from PURCHASER.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In the event that DSC and PURCHASER cannot agree
on a price for such volumes, PURCHASER shall have the right to buy at own risk and cost 1,3-Butadiene and DSC commits to provide the use of the loading, unloading, storage and transport systems of ELENAC, at a cost to be agreed between DSC and
PURCHASER from time to time.
