WHEREAS, Buyer and Seller are parties to that certain Propylene Supply Contract effective September 29, 2009 (hereinafter “Contract”), and;

WHEREAS, the Parties desire to amend the Contract in the respects set forth below;

NOW, THEREFORE, for and in consideration of the mutual covenants and agreements herein expressed, and for other good and valuable consideration, receipt and sufficiency of which are hereby acknowledged, Buyer and Seller hereby amend the Contract and agree as follows:

1.                                       Capitalized terms herein not otherwise defined will have the meanings ascribed to such terms in the Contract.

2.                                       The Section of the Contract entitled Purchase Price is modified by striking the current text and substituting the following:

“During the Contract Term, the price per pound for PGP Product (hereinafter “PGP Purchase Price”) and/or for CGP Product (hereinafter “CGP Purchase Price”), as applicable, will be determined as follows:

(i)                                     Each Month the Parties will enter into good faith negotiations in an attempt to arrive at a reference price, hereinafter referred to as the “PGP Reference Price” for PGP and/or the “CGP Reference Price” for CGP, for the calendar month in which deliveries are being made, which reference price accurately reflects the price generally accepted by buyers and sellers of large volumes of Product delivered via pipeline in the Gulf Coast region (excluding all discounts or allowances) during such month.  If the Parties fail to agree on a particular reference price prior to the end of the calendar

1

month, and absent any mutual agreement by the Parties to extend negotiations for the month in which the reference price is being negotiated, then the PGP Reference Price and/or CGP Reference Price for such month will be calculated in accordance with the settled PG Propylene, Contract Benchmark and/or CG Propylene Contract, Benchmark, as applicable, as published in the North America Product Prices table, Cents/Pound column, CMAI MONOMERS MARKET REPORT (the “PG Propylene Contract, Benchmark” and “CG Propylene Contract, Benchmark,” respectively) for the month of delivery.

(ii)                                  Once the PGP Reference Price and/or CGP Reference Price, as applicable, have been determined, the PGP Purchase Price and/or CGP Purchase Price, as applicable, will then be reduced by a discount of ***** percent (*****%); provided, however, such discount, as applied to each of the PGP Reference Price and/or the CGP Reference Price to arrive at the PGP Purchase Price and/or CGP Purchase Price, respectively, will not be greater than ***** cents per pound.

(iii)                               If for any given calendar month the Parties are unable to agree on either the PGP Reference Price and/or the CGP Reference Price, and the PG Propylene Contract, Benchmark and/or the CG Propylene Contract, Benchmark in the CMAI MONOMERS MARKET REPORT fail to settle prior to invoicing, then unless otherwise expressly agreed by the Parties, the provisional PGP Reference Price and/or the provisional CGP Reference Price, as applicable, for such month will initially be either the PG Propylene Contract, Benchmark and/or CG Propylene Contract, Benchmark, as applicable, for the immediately preceding month or the last settled month of delivery, as the case may be.  Once the PG Propylene Contract, Benchmark and/or CG Propylene Contract, Benchmark, as applicable, in the CMAI MONOMERS MARKET REPORT have settled for the calendar month of delivery, Seller will promptly reissue the invoice for the month in question, which invoice will provide the appropriate adjustment to reflect the change to the appropriate PGP Purchase Price and/or CGP Purchase Price, as applicable; any additional amounts owing by Buyer will be paid within fifteen (15) days of the receipt of such invoice and any credits owing to Buyer will be applied to the next invoice delivered by Seller.

(iv)                              If in any given calendar month the Parties are unable to agree on either the PGP Reference Price and/or the CGP Reference Price, and the PG Propylene Contract, Benchmark and/or the CG Propylene Contract, Benchmark, as applicable, in the CMAI

2

MONOMERS MARKET REPORT have settled for the month of delivery as a range, then the PGP Purchase Price and/or CGP Purchase Price, as applicable, will be calculated using the arithmetic average of the published PG Propylene Contract, Benchmark and/or CG Propylene Contract, Benchmark range, as applicable,

(v)                                 In the event the CMAI MONOMERS MARKET REPORT ceases publication, or the monthly publications of the benchmark prices needed to calculate the PGP Reference Price and/or CGP Reference Price cease or no longer reflect actual market conditions, then Buyer and Seller agree to negotiate, in good faith, a suitable replacement that, to the extent possible, will allow calculation of the PGP Reference Price and/or CGP Reference Price in a manner consistent with the original intent of this Contract.”

3.                                       The Section of the Contract entitled Delivery Point is modified by adding the following:

“For Buyer’s Exchange Balance (as defined in Attachment C), there will be no Delivery Point in connection with the initial purchase by Buyer; however, when the Buyer’s Exchange Balance is ultimately received by Buyer, the Delivery Point will be, either (i) the Exxon CGP pipeline system for delivery to Buyer at the INEOS Nitriles Green Lake facility located in Calhoun County, Texas, or (ii) such other locations as are mutually agreed upon in writing by Buyer and Seller.”

4.                                       The Section of the Contract entitled Delivery/Title Transfer is modified by adding the following:

“For Buyer’s Exchange Balance (as defined in Attachment C), title to, beneficial interest in, risk of loss for, and possession and control of the Product will pass to Buyer at the Delivery Point.”

7.                                       Terms and Conditions, Section 5 — Quantity and Nominations, is modified by adding the following:

“5.3 Buyer’s nomination will designate the quantity of Product, if any, nominated from Buyer’s Exchange Balance (as defined in Attachment C).”

8.                                       Terms and Conditions, Section 12.5, is modified by striking the current text and substituting the following:

“The obligations of the Parties under Sections 3, 4.3, 7, 10, 12, and Attachment C will survive termination, cancellation, or expiration of this Contract.
