BUTADIENE SALES CONTRACT (EUROPE)

BETWEEN

DOW EUROPE GMBH

AND

STYRON EUROPE GMBH

Amended and Restated Sales Contract (this “Contract”)

Date of Contract: June 17, 2010

Seller agrees to sell and supply to Buyer the Product described in this Contract out of the production plants of Dow Benelux B.V. Terneuzen, the Netherlands and Dow Olefinverbund GmbH Boehlen, Germany or any alternate source subject to qualification, and Buyer agrees to purchase and receive from Seller such Product into Buyer’s Product consuming plants in Terneuzen, Rheinmuenster, Hamina, Norrkoeping, Livorno or Schkopau according to the TERMS AND CONDITIONS set out below.

	Dow Europe GmbH Bachtobelstrasse 3 8810 Horgen – Switzerland (“Seller”)
	Styron Europe GmbH Bachtobelstrasse 3 8810 Horgen – Switzerland (“Buyer”, each of Buyer and Seller a “Party”, and collectively, the “Parties”)
1.        Product	Butadiene
2.        Specification	Dow standard sales specification 12852-S for all Buyer’s Product consuming plants except for Rubber. Specification attached hereto as Appendix A and made part of this Contract.
	Customer specification 12852-C101 for Buyer’s Product consuming Rubber plants ex Terneuzen. Specification attached hereto as Appendix B and made part of this Contract.
	Customer specification 12852-C 100 for Buyer’s Product consuming Rubber plants ex Boehlen. Specification attached hereto as Appendix C and made part of this Contract
3.      Quantity	Buyer shall buy a minimum quantity of [*****] (“Minimum Quantity”) and Seller shall sell a maximum quantity of [*****] (“Maximum Quantity”).
	If Seller has additional quantities available to offer Buyer and Buyer is willing to buy, Seller will provide Buyer with first right of refusal to buy such additional quantity of Product under the terms of this Contract.
4.        Price/Currency (EXCLUSIVE OF VAT)	The following price formula shall apply, invoiced in EUR/MT:
	The base price will be negotiated by Buyer and Seller on the 25th of the month for the following month. If Buyer and Seller fail to agree on the base price for any month, the base price will be equal to [*****] for the month in question. The base price will be adjusted to an FCA price before adding actual freight, by means of the following formula:
	[*****] + actual freight to the receiving site
	Where actual freight is the rail freight from Terneuzen to rail served sites, the shipping cost to Hamina from Terneuzen, or pipeline transfer costs from either Boehlen or Terneuzen for deliveries to Latex Terneuzen or Rubber Schkopau
	Where €[*****] fee represents an average freight cost for Butadiene sellers in NWE and will be adjusted annually with inflation

Page 2 of 18

	Should the ICIS mechanism move to an FCA basis, the €[*****] freight adjustment will no longer be applied and the formula will be as follows:
	[*****] + actual freight to the receiving site
	At the end of the first eighteen (18) month period and each thirty-six (36) month period thereafter, upon at least twelve (12) months prior written notice by either Buyer or Seller, Seller and Buyer shall reserve the right to negotiate in good faith a mutually agreeable alternative to the above price mechanism. In the event that the Parties are unable to agree upon an alternative price mechanism within thirty (30) days after initiating negotiations, then Buyer and Seller must elevate the negotiations to senior management of each Party.
	If senior management cannot reach agreement within thirty (30) days of elevation, then the pricing negotiation becomes a dispute to be arbitrated by a reputable industry consultant, such as CMAI, to be mutually agreed upon by Buyer and Seller; provided, however, that during periods of such arbitration the price mechanism shall continue under the then current price mechanism until the resolution of such arbitration. Fees and costs for the arbitrator shall be shared equally between Buyer and Seller. The decision by the arbitrator shall be the new price starting on the date the arbitrator issues the decision and shall continue for the next thirty-six (36) month period. For the avoidance of doubt, Section 13 of the Dow H&E GENERAL TERMS AND CONDITIONS shall not apply to a pricing dispute pursuant to this Section 4.
	In the event any of the indices referenced above ceases publication, stops reporting on Butadiene, materially changes its format for price reporting, or modifies the fundamental basis for price reporting, Seller and Buyer reserve the right to negotiate in good faith a mutually agreeable alternative to the above price mechanism. In the event that the Parties are unable to agree upon an alternative price mechanism within thirty (30) days after initiating negotiations, then Buyer and Seller must elevate the negotiations to senior management of each Party. If senior management cannot reach agreement within thirty (30) days of elevation, then the pricing negotiation becomes a dispute arising under this Contract and is settled pursuant to the terms of Section 13 of the Dow H&E GENERAL TERMS AND CONDITIONS.
5.        Period of Contract	This Contract is effective as of June 17, 2010 and shall continue to be in effect for ten (10) years and x months from this date (n.b. termination should be at year end), and shall continue for two(2) year periods thereafter until terminated by either Party with at least twelve (12) months prior written notice, unless previously terminated in writing in accordance with Section 18 of this Contract, without prejudice to any other right of termination a Party may have in accordance with the terms hereof.

If payment due date falls on a Sunday or a holiday on a Monday, payment shall be made on the next banking day.

3. When using ASTM D4629 result must be corrected by extracting concentration of N from extraction solvent.

Acetonitrile: Result – Extraction solvent [*****]

N-methylpyrrolidone: Result – Extraction solvent [*****]

4. Requirement for barge/ship/rail transfers only. Not applicable to pipeline transfers. This parameter will not be routinely analyzed by Terneuzen based on operating discipline which minimizes oxygen level in railcars.
