PROPYLENE SUPPLY CONTRACT

This Propylene Supply Contract (“Contract”) is effective as of September 30, 2009 between PL Propylene LLC, a Delaware limited liability company (“Seller”), and TOTAL PETROCHEMICALS USA, INC., a Delaware corporation, with its principal offices located at 1201 Louisiana, Suite 1800, Houston, Texas 77002 (“Buyer”; Seller and Buyer are collectively referred to herein as the “Parties”). Subject to the terms and conditions contained herein, Seller agrees to sell and deliver and Buyer agrees to purchase and accept delivery of the product described below, in the quantities and during the period set forth in this Contract.

Contract Term:		The term of deliveries under this Contract shall commence on the Commencement Date and will continue until December 31, 2014 (“Contract Term”), and thereafter will continue subject to either Party’s right to terminate as of December 31, 2014, or as of December 31st of any year thereafter by giving at least twelve (12) Months prior written notice.

		If the Contract Term is extended beyond December 31, 2014, then the term “Contract Term” shall include such extended period of time; and for each additional year all of the terms and conditions set forth herein shall remain the same, including, without limitation, the purchase price (“Purchase Price” as set out in the Purchase Price Section below) and the quantity of Product Seller shall sell and Buyer agrees to purchase.

Commencement Date:		Except as otherwise set forth herein, the “Commencement Date” shall occur on November 1, 2010. Prior to the Commencement Date, Seller shall have no obligation to sell and deliver Product and Buyer shall have no obligation to purchase and accept Product: provided, however, the Parties may mutually agree to sell and purchase Product prior to the Commencement Date on the terms and conditions of this Contract but in no event will Buyer have an obligation to purchase the minimum Monthly quantity requirement of Product (set forth below).

		Seller shall keep Buyer informed of Seller’s projected completion date for the propylene production facility. Prior to Commencement Date. Seller shall have the option on up to two occasions to delay the Commencement Date: provided however, Seller shall notify Buyer of any such delay by providing at least ninety (90) days prior written notice to Buyer. In no event shall the Commencement Date be delayed beyond January 1, 2011 except for the occurrence a Force Majeure Event as provided below. If Seller sends a notice extending the Commencement Date, then the new

		date set forth in such notice shall for all purpose be the “Commencement Date”.

		The Commencement Date shall be subject to extension due to a Force Majeure Event.

		In the event the Seller is unable to commence deliveries of Product to Buyer under this Contract on the Commencement Date, then until the completion of the construction of Seller’s propylene plant and Seller’s commencement of deliveries required hereunder, Buyer’s sole remedy shall be the right to procure replacement quantities of Product, up to a Monthly quantity of 21.750.000 pounds, and charge Seller with the additional costs paid by Buyer for such replacement quantities in excess of the costs that Buyer would have been obligated to pay Seller hereunder. As to any replacement quantities purchased by Buyer, Buyer shall use commercially reasonable efforts to minimize the purchase price of such replacement Product.

		If the completion of the construction of Seller’s propylene plant and Seller’s commencement of deliveries required hereunder has not occurred by March 31, 2011, and such delay has not been caused by Force Majeure Event(s), then Buyer shall have the right to terminate this Contract by providing Seller with thirty (30) days prior written notice, which notice must be provided, if at all, prior to the completion of the construction of Seller’s propylene plant and Seller’s commencement of deliveries required hereunder.

Product(s):		A combination of Polymer Grade Propylene (“PGP”), meeting the specifications and other quality standards set forth in Attachment A-1 attached hereto, and Chemical Grade Propylene (“CGP”), meeting the specifications and other quality standards set forth in Attachment A-2 attached hereto (collectively, the -Specifications”). The PGP and CGP to be purchased hereunder may be referred to in this Contract collectively and individually as “Product.”

Quantity:		During the Contract Term, Seller agrees to sell and Buyer agrees to purchase and pay for the following quantity of Product:

		Subject to proration for the year in which the Commencement Date occurs (as set forth above), Buyer shall purchase no less than 222,000.000 pounds per calendar year of Product and Seller shall sell no less than 222,000,000 pounds per calendar year of Product and shall not be required to sell more than 300.000,000 pounds per calendar year of Product.

		For each calendar month (“Month”) during the Contract Term, the minimum Monthly quantity of Product that Buyer shall purchase and Seller shall provide is 18,500.000 pounds and the maximum Monthly

		quantity of Product that Buyer may purchase is 25.000.000 pounds. Notwithstanding the foregoing, during the Contract Term, Buyer’s facilities will be shutdown from time to time in connection with planned maintenance, planned construction projects or other planned outages (“Turnarounds”). Provided Buyer gives Seller at least 60 days notice in writing of any Turnarounds, then Buyer shall not be obligated to purchase the minimum Monthly quantity of Product required to be purchased herein. Notwithstanding any Turnarounds, Buyer shall nonetheless be obligated to purchase for each calendar year a minimum of 222,000,000 pounds of Product.

		It is contemplated by the Parties that the Product to be purchased hereunder will be PGP. Notwithstanding the foregoing, upon the occurrence of events that reduce Buyer’s need for PGP, Buyer may specify that all or a portion of the Monthly quantity of Product be comprised of quantities of CGP.

		The Quantity of Product for the Month in which the Commencement Date occurs will be prorated for that Month based on the number of days remaining in the Month from the Commencement Date divided by the number of days in such Month.

		All quantities of Product shall be purchased and paid for on a stream basis.

Purchase Price:		During the Contract Term, the per pound price for PGP Product (“PGP Price”) and CGP Product (“CGP Price”), as applicable, will be determined as follows: Each Month the Parties shall enter into good faith negotiations in an attempt to arrive at a reference price (the “PGP Reference Price” for PGP and the “CGP Reference Price” for CGP) for the Month in which deliveries are being made, which reference price accurately reflects the price generally accepted by buyers and sellers of large volumes of pipeline delivered Product 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 a Month, then absent any mutual agreement by the Parties to extend negotiations for the Month in which the reference price is being negotiated, the PGP Reference Price for such Month will equal the “PG Propylene Contract, Benchmark” price as published Monthly by CMAI in the Monomers Market Report in cents per pound for the Month of delivery, and the CGP Reference Price for such Month will equal the “CG Propylene Contract. Benchmark” price as published Monthly by CMAI in the Monomers Market Report in cents per pound for the Month of delivery.

		Once the PGP Reference Price and the CGP Reference Price, as applicable, have been determined, the PGP Price and CGP Price, as applicable, shall equal the applicable reference price reduced by a discount of *** (***%); provided, however: (i) for the time period from the

		Commencement Date through forty-two (42) Months following the Commencement Date (the “Initial Period”), such discount will be capped at $*** per pound, and (ii) for the time period from the first day following the conclusion of the Initial Period, through December 31, 2014 (or any additional period of time by which the Contract Term may be extended beyond December 31, 2014) such discount will be capped at $*** per pound.

		For example: For the Month of October 2008, (i) the “PG Propylene Contract, Benchmark” price was $*** per pound and the PGP Price (applying a discount of $* per pound) would have been $* per pound: (ii) the “CG Propylene Contract. Benchmark” price was $* per pound, and the CGP Price (applying a discount of $* per pound) would have been $*** per pound.

		If for any given Month the Parties are unable to agree on either the PGP Reference Price or the CGP Reference Price and CMAI fails to report either the “PG Propylene Contract, Benchmark” or the “CG Propylene Contract, Benchmark”, as applicable, prior to invoicing, then unless otherwise expressly agreed by the Parties, the applicable reference price for such Month will initially be either the “PG Propylene Contract, Benchmark” or the “CG Propylene Contract, Benchmark”, as applicable, for the immediately preceding Month. Once the appropriate Monthly price is reported by CMAI in the Monomers Market Report, Seller shall promptly reissue the invoice for the Month in question, which invoice shall provide for the appropriate adjustment to reflect the change to the appropriate Monthly price. Any additional amounts owing by Buyer shall be paid within 15 days of the receipt of such invoice and any credits owing to Buyer shall be applied to the next invoice delivered by Seller.

		If in any given Month the Parties are unable to agree on either the PGP Reference Price or the CGP Reference Price and a range of prices are reported by CMAI for such Month for the applicable benchmark, then the applicable CMAI price to be used hereunder for calculating the Purchase Price shall equal the arithmetic average of the CMAI listed benchmark prices for the applicable Product.

		In the event the CMAI Monomers Market Report ceases publication or ceases to be published Monthly or the benchmark prices needed to calculate either the PGP Reference Price or the CGP Reference Price are no longer provided or no longer reflect actual market conditions, then the affected Purchase Price will be based upon an alternative index price which most closely approximates the subject index as of the Commencement Date of this Contract and is mutually agreeable to both Parties.

Delivery Points:		Seller will deliver Product to the following locations (“Delivery Points-): (i) for PGP (a) the outlet of the first flange of Seller’s custody meter to be located at the TOTAL Polypropylene Plant located in La Porte, Texas (“La Porte Facility”); or (b) such other locations on Seller’s pipeline that are mutually agreed upon in writing by the Parties, with such agreement not to be unreasonably withheld; (ii) for CGP (a) such locations on Seller’s pipeline delivery system that are mutually agreed upon in writing by the Parties, with such agreement not to be unreasonably withheld; or (b) such locations along a third party’s pipeline system to which Seller has access, if any, and that are mutually agreed upon in writing by the Parties, with such agreement not to be unreasonably withheld.

		If Seller delivers Product to a Delivery Point other than the La Porte Facility. Buyer agrees to reimburse Seller for all third party transportation and/or exchange fees Seller incurs in connection with the delivery of Product to such other Delivery Point.

Delivery/ Title Transfer:		Deliveries of Product will be made to Buyer at the Delivery Points. Subject to the provisions set out in Attachment C as to the Seller’s Exchange Balance (as defined therein), title to, risk of loss for, and possession and control of the Product will pass from Seller to Buyer at the specific Delivery Points.

Invoicing/Payment Terms:		Seller shall provide Buyer with a Monthly consolidated invoice (by electronic means or facsimile) for the prior Month’s shipments on or before the fifth (5th) day of the Month following such shipments. All amounts due hereunder, including without limitation, any delivery or transportation fees, with respect to any Month shall be due and payable by wire transfer to an account designated by Seller in immediately available United States funds no later than fifteen (15) days after Buyer’s receipt of Seller’s invoice.

Special Provisions:		In order to address potential Product imbalances for any given Month, the Parties shall comply with the exchange arrangements more fully described on Attachment C attached hereto.

		In consideration of the arrangements set out on Attachment C, promptly after the execution of this Contract, Buyer and PL Olefins LLC (“PL Olefins”) will enter into a separate storage and transportation agreement (“Storage and Transportation Agreement”) containing the following terms and such other terms and conditions that are mutually agreed to by the Parties. The Storage and Transportation Agreement will be coterminous with the terms of this Contract and will provide Buyer with the ability to store up to 10.000,000 pounds of ethylene at the Choctaw underground storage facilities and terminal owned and operated by PL Olefins located near Plaquemine, Louisiana in Iberville Parish. Seller will be responsible

for paying on Buyer’s behalf the base cost of such storage capacity. Buyer will be responsible for the loss provisions attributable to its stored ethylene, the other storage charges referenced therein as Buyer’s responsibility, and all transportation and/or delivery fees payable thereunder.

This Contract includes (i) the foregoing terms (“Specific Terms”), (ii) the Terms and Conditions attached hereto, and (iii) the Attachments attached hereto. THE TERMS AND CONDITIONS AND ATTACHMENTS ATTACHED HERETO ARE INTEGRAL PARTS OF THIS CONTRACT AND ARE INCORPORATED INTO THIS CONTRACT AS IF FULLY SET FORTH HEREIN.

The Easement Agreement shall be finalized and executed by the Parties as soon as reasonably possible. It is expressly agreed that the provisions of the Easement Agreement will control with respect to liability of the Parties for bodily injuries and/or property damage occurring in connection with the work performed on the easement with respect to the installation and operation of the delivery pipeline into the LaPorte Facility by Seller and its employees, agents, contractors and representatives.

PROPYLENE MEASUREMENT

CUSTODY TRANSFER/MASS MEASUREMENT PROTOCOL
PROPYLENE TURBINE METER WITH DENSITOMETER

Polymer Grade Propylene and Chemical Grade Propylene

SECTION I - METERING EQUIPMENT

Polymer Grade Propylene and Chemical Grade Propylene delivered or received by Seller shall be measured by MASS MEASUREMENT PROCEDURES using a turbine meter.

Polymer Grade Propylene shall be measured by Mass measurement procedures in accordance with AGA-3, MPMS, GPA standards and/or procedures agreed to by both parties. The determination of the flowing density of the polymer grade propylene shall be calculated by the flow computer using the API density table as found in API MPMS Chapter 11.3.3.2.

Chemical Grade Propylene shall be measured by Mass measurement procedures in accordance with AGA-3, MPMS, GPA standards and/or procedures agreed to by both parties. The determination of the flowing density of the chemical grade propylene shall be calculated by the use of a densitometer.

Each metering station shall be equipped with: a flow computer capable of calculating mass; temperature and pressure transmitters. Additionally, each chemical grade propylene meter shall be equipped with a densitometer for measuring product density.

The metering station shall be installed in such a manner that a minimum back-pressure of 1.5 times the product vapor pressure at maximum operating temperature is maintained at all times. Measurement accuracy shall not be impeded by the effects of pulsation created by pumps or other sources.

All equipment employed in metering and sampling shall be approved as to the type, materials of construction, method of installation, and maintenance by all parties involved in the custody transfer of products. Due consideration shall be given to the operating pressure, temperature, and characteristics of the product being measured.

Turbine Meters shall be installed and operated in accordance with the MPMS, Chapter 5. “Metering”, Sections 3 & 4. Each turbine meter shall be proved monthly or when accuracy is in question using a ball or piston-type or small volume prover in accordance with the MPMS, Chapter 4, “Proving Systems.” The meter shall be repaired or replaced anytime the meter shift is greater than +/- 0.0050 from its established historical meter factor for that flow rate, or anytime the factor shifts by more than 0.0025 from one proving to the next. The meter shall be reproved anytime the current operating flow rate would cause a change in meter factor greater than +/¬0.0010 from the meter factor being used. A copy of all meter curves, meter provings, and prover certification data shall be provided to the customer.

Densitometers with frequency output shall be installed and proved in accordance with the MPMS, Chapter 14, Section 6, “Continuous Density Measurement.” The frequency output may be driven directly into a flow computer capable of internally converting frequency to corrected flowing density in gm/cc (preferred), or, to a separate frequency converter and into the flow computer as a 4-20 mA signal (not preferred). Proving the densitometer is to be by entrapping a sample of the flowing stream at system conditions in a high-pressure vessel known as a pycnometer. The connections for the pycnometer shall be installed in the same manner as those of the densitometer. Thermowells shall be installed to allow monitoring of the inlet and outlet temperature. Accuracy of the densitometer shall be verified monthly or when accuracy is in question and shall be within +/- 0.001 gm/cc over its entire range and repeatable within +/¬0.0005 gm/cc.

Temperature and Pressure Transmitters shall be verified monthly using a certified thermometer and reference gage respectively to ensure current readings are within +/-0.2 degree F and +/- 1 psi. A full five (5) point calibration shall be performed at least once quarterly. All verification and calibration data shall be supplied to Buyer. Accuracy of these devices shall be +/- 0.05% of scale.

Flow Computers shall be installed and operated in accordance with MPMS, Chapter 21.2, “Flow Measurement Using Electronic Metering Systems” and shall be capable of accepting turbine pulses and signals from the pressure, temperature, and density transmitters. The computer shall convert, as required, and totalize these signals into daily mass values

Meters, instruments, and check metering systems shall be calibrated or proved at least once each month. Sufficient notice shall be given to all parties to permit a representative of each to be present. Reference to any API, ASTM, GPA, or similar publication shall be deemed to encompass the latest edition, revision, or amendments thereof.

SECTION II - ACCOUNTING AND MEASUREMENT PROCEDURES

I. CUSTODY TRANSFER TICKETS

Seller shall furnish to Buyer daily custody transfer tickets, unless otherwise provided for by contract, for products measured. The ticket will identify the product and state the Total Mass to the nearest 1.0 pound-mass. An unfinished batch shall be closed out at 2400 hours on the last day of the month, unless otherwise provided for by contract.

II. MEASUREMENT BASIS

A. MASS MEASUREMENT

Mass measurement shall be accomplished utilizing a, turbine meter, densitometer for chemical grade propylene or API table for chemical grade propylene, and flow computer to convert volume and density at flowing conditions to total pounds mass according to the following formula:

Total Mass = Volume at flowing conditions X MCF X Density at flowing conditions X DCF = Pounds

Volume is in gallons

Density is in pounds per gallon

MCF is meter correction factor

DCF is densitometer correction factor

For polymer grade propylene the DCF will not apply or be 1.0.

III. PROVINGS AND TOLERANCES

Provings shall meet the recommendations of API Chapters 14.6 and the appropriate sections of API Chapter 4.

A. General

1. Meter provings, calibration of instruments, and maintenance of measurement equipment will normally be performed by Seller’s personnel or may be delegated to responsible third-party contractors under the direction of Seller’s representative.

2. The signature of Buyer’s witness does not constitute the approval of the use of out-of tolerance equipment, but said signature does attest to the validity of the proving report. Note that a valid report may say the system performance was satisfactory or unsatisfactory, as appropriate.

B. Proving Intervals

Each meter shall be proven when initially placed into service. Subsequent provings shall be made every thirty (30) days, unless in accordance with the MPMS, Chapter 4.8.2.10, the consistency of the meter factor allows the proving interval to be extended. The Statistical Quality Control (SQC) tracking of the meter factor may allow extension of the interval between provings to sixty (60) days with written approval of Buyer. The meter shall be proven as soon as possible after any meter maintenance is performed.

C. Meter Factor

1. Meter proving calculations shall be in accordance with API Standards. The average of five (5) consecutive prover runs shall be taken to establish an initial or new meter factor, provided that the five (5) proving runs are within 0.0005 (0.05%) of each other and the meter factor is within 0.0025 (0.25%) of the previous meter factor under like operating conditions.

2. The new meter factor shall be used after each successful proving if it meets the above proving criteria.

3. If the new meter factor deviates from the previous meter factor under like operating conditions by more than plus or minus 0.0025, then one half (1/2) of the volume measured since the previous proving shall be corrected using the new meter factor. If the time of malfunction can be determined by historical data, then the volume measured since that point in time shall be

corrected using the new meter factor. The new meter factor shall not be used to correct volumes measured more than 31 days prior to the new proving.

4. No work shall be performed on the measuring element of a turbine meter without 24 hour notice being given to Buyer except in case of an emergency and proving the meter. If any work is performed, a new meter factor shall be established.

5. If the new meter factor deviates 0.0025 or more, the element shall be removed and inspected. If there is build-up on the internals, then the element shall be cleaned and the meter re-proved. If excessive wear is found, then the element shall be repaired or replaced and the meter re-proved to establish a new initial meter factor. After a 24-hour wear-in period, the meter shall be re-proved and if the meter factor changes more than +/- 0.0015 from the new initial meter factor, then one-half (1/2) of the volume measured shall be corrected using the latest meter factor.

6. The measurement technician shall record all required corrections to measured volumes and shall describe the findings, method of repair, and calculations used in making the correction on the meter proving report. A correction ticket for the amount of the correction shall be issued.

D. Density Factor

The average of two (2) successive pycnometer provings shall establish product flowing density, provided the two (2) successive provings agree within 0.0005 (0.05%). The new factor should agree with the old factor within 0.0025 (0.25%). If it does not, the density meter should be cleaned and/or repaired as required.

IV. CUSTODY MEASUREMENT STATION FAILURE

If a failure occurs on a custody measurement station or the station is out of service while product is being delivered, then the volume shall be determined or estimated by one of the following methods in the order stated:

1. By using data recorded by any check measuring equipment that was accurately registering; or

2. By correcting the error if the percentage error can be ascertained by calibrations, tests, or mathematical calculations; or

3. By comparison with deliveries made under similar conditions when the measurement station was registering accurately.

4. By using historical pipeline gain/loss.

DEFINITIONS

A. “Day” shall mean a period of twenty-four (24) consecutive hours commencing at a local time agreed on by all parties involved.

B. “Gallon” shall mean an U.S. Gallon of 231 cubic inches of liquid at sixty degrees (60 °F) Fahrenheit and at the equilibrium vapor pressure of the liquid.

C. “Barrel” shall mean forty-two (42) U.S. Gallons.

D. Pound shall mean a unit of weight equivalent to 16 ounces avoirdupois.
