Sterling shall use reasonable efforts to comply with the Estimated Delivery, Shipment and Storage Instructions and the Delivery, Shipment and Storage Instructions, and shall give BASF the same rights of priority and scheduling with respect thereto that it uses for deliveries and shipments of its own raw materials and products and those of Sterling’s other suppliers and customers. BASF may also deliver to Sterling from time to time additional delivery, shipment and storage instructions and Sterling shall use reasonable

efforts to receive Raw Materials, deliver Products and store Raw Materials and Products at the times specified in such instructions; provided, however, that if such additional delivery, shipment and storage instructions cause Sterling to incur additional expense, BASF shall reimburse Sterling for such additional expense. All such additional delivery, shipment and storage instructions shall be given as early as is practicable prior to the requested delivery, shipment or storage date but, in any event, at least as far in advance of the requested date of delivery, shipment or storage as is required for Delivery, Shipment and Storage Instructions. If BASF fails to provide any ship, barge, other inland water or marine vessel, rail car, tank truck or other conveyance at the times specified in the applicable Estimated Delivery, Shipment and Storage Instructions, Delivery, Shipment and Storage Instructions or additional delivery, shipment and storage instructions, the applicable ship, barge, other inland water or marine vessel, rail car or tank truck will not be loaded or unloaded until the next available window for such method of transportation at the Site.

     (c) If BASF fails to take delivery of any Product that meets the applicable Product Specifications and is tendered to it by Sterling pursuant to the Estimated Delivery, Shipment and Storage Instructions, the Delivery, Shipment and Storage Instructions or additional delivery, shipment and storage instructions, Sterling shall have the right to reduce or curtail production of Products if (i) such failure to take delivery will result in the exceedance of storage capacity at the Site and BASF does not provide for, or agree to allow and to pay for, outside storage, or (ii) BASF’s failure to take delivery will result in the need to shut down any Unit. Except to the extent otherwise provided in this Agreement, a failure to take delivery of any Products by BASF shall not limit its payment obligations hereunder. The taking of delivery of Products by BASF shall not prejudice the right of BASF to dispute or question the quantity or quality of any Products delivered hereunder pursuant to Sections 2.05 and 2.06 or limit or otherwise affect the indemnity obligations of Sterling under Section 6.01(a).

     (d) Notwithstanding anything to the contrary contained in this Agreement, (i) BASF shall not, in any Estimated Delivery, Shipment and Storage Instructions, Delivery, Shipment and Storage Instructions or additional delivery, shipment and storage instructions, request the delivery of, and Sterling shall not be required to deliver, any Product in any Month in quantities in excess of the Monthly Contract Capacity for such Product, and (ii) except as otherwise provided in Section 6.02(a), Sterling shall not be required to purchase any Product from any other source in order to supply such Product to BASF hereunder; provided, however, that, notwithstanding anything to the contrary contained in clause (i) above, BASF may request delivery of any Product in excess of the Monthly Contract Capacity for such Product if the relevant Unit is capable of producing such Product in quantities in excess of the Monthly Contract Capacity, in which event BASF shall be solely responsible for any and all incremental costs and expenses incurred by Sterling in connection with producing such Product in quantities in excess of the Monthly Contract Capacity, and such costs and expenses shall be excluded from any calculation of Costs Savings or the Threshold Fixed Costs Amount under this Agreement and, to the extent such costs and expenses are Allocated Fixed Costs, shall be paid separately from, and in addition to, the Allocated Fixed Costs Amount. Prior to any material expansion, upgrade or change in design, layout,

configuration or capacity of any Unit, including any change in catalyst, the Parties shall discuss such expansion, upgrade or change.

     (f) BASF acknowledges and agrees that production of more than *** pounds of PA in any Month prior to the completion of the New Switch Condenser Project or another Expansion Project pertaining to the PA Unit will likely result in decreased yields from the Raw Materials for PA, including orthoxylene, and higher Fixed Costs and Variable Costs. In the event that BASF desires for Sterling to produce more than *** pounds of PA in any Month prior to the completion of the New Switch Condenser Project or another Expansion Project pertaining to the PA Unit, (i) any increase in Fixed Costs resulting from such excess production shall be excluded from any calculation of Cost Savings or the Threshold Fixed Costs Amount, (ii) to the extent such costs and expenses are Allocated Fixed Costs, shall be paid separately from, and in addition to, the Allocated Fixed Costs Amount and (iii) for purposes of determining whether any Cost Savings have resulted in the Year in which such Month falls, the per pound usage for each component of Variable Costs in such Month shall be deemed to be the same as the per pound usage of such component of Variable Costs experienced in the most recent Month during which such excess production did not occur.

     (g) Notwithstanding anything to the contrary contained in this Agreement, Sterling shall not be required to use the Old Switch Condensers to produce any PA hereunder. Sterling shall take the actions set forth on Exhibit E in order to decommission the Old Switch Condensers and remove them from service, and BASF shall reimburse Sterling for (i) *** of the first *** in costs and expenses associated with the engineering required to define the scope of work and procedures to isolate the Old Switch Condensers plus *** of any costs and expenses associated with such engineering to the extent such costs and expenses exceed ***, plus (ii) *** of the first *** in costs and expenses to perform the actions set forth on Exhibit E and *** of the next *** of such costs and expenses, in each case, within 15 Days after receipt of an invoice

therefore from Sterling. Both Parties shall cooperate to minimize the costs associated with performing such actions while ensuring that all environmental, health, and safety issues are adequately addressed. In the event that such costs and expenses exceed or are expected to exceed ***, prior to conducting any further decommissioning activities, the Parties shall determine what further actions are required in connection with the decommissioning of the Old Switch Condensers and set a budget therefore. BASF shall reimburse Sterling for *** of the costs and expenses to perform such additional actions (not to exceed *** of the agreed budget) within 15 Days after receipt of an invoice therefore from Sterling. *** BASF shall reimburse Sterling for any and all costs and expenses required to maintain the Old Switch Condensers in place in a safe and environmentally responsible manner and such costs and expenses shall be excluded from any calculation of Cost Savings or the Threshold Fixed Costs Amount and, to the extent such costs and expenses are Allocated Fixed Costs, shall be paid separately from, and in addition to, the Allocated Fixed Costs Amount.

Each Party acknowledges and agrees that (a) material handling services will be provided by Sterling on a 24-hours a Day, 365/366 Days a year basis, (b) laboratory services will be provided by Sterling only between the hours of 6:30 a.m. and 11:30 p.m. (Houston, Texas time), Monday through Friday, and (c) customer and scheduling services will be provided by Sterling only between the hours of 7:30 a.m. and 4:00 p.m. (Houston, Texas time), Monday through Friday.

          Section 2.09. Option to Terminate Obligations With Respect to the Oxo Unit. (a) In consideration of the payment of the Oxo Unit Termination Option Payment, and subject to the terms and conditions of this Agreement, BASF shall have the right to terminate its obligations hereunder with respect to the operation of the Oxo Unit by providing Sterling with written notice of its exercise of such right, which notice shall specify the date upon which BASF’s obligations with respect to the operation of the Oxo Unit will terminate (the “Exercise Date”); provided, however, that (i) if the Exercise Date is on or before December 31, 2007, the Exercise Date must be at least three months after the date on which Sterling receives such notice, and (ii) if the Exercise Date is after December 31, 2007, the Exercise Date must be at least six months after the date on which Sterling receives such notice. If BASF exercises its right under this paragraph (a), BASF shall be responsible for all costs and expenses associated with converting operations from manufactured Oxo-Alcohols to delivered Oxo-Alcohols; provided, however, that pursuant to Section 3.02(c) Sterling shall be solely responsible for the first *** of costs and expenses incurred in connection with the conversion of the existing Oxo-Alcohols storage tanks from manufactured Oxo-Alcohols service to delivered Oxo-Alcohols service.

          (b) If BASF exercises its rights under paragraph (a) above and, within 30 Days after the Exercise Date, Sterling elects to permanently close the Oxo Unit by providing written notice of such election to BASF within such 30-Day period:

     (i) BASF shall have the right, in its sole discretion, to purchase the *** from the Oxo Unit from Sterling for *** if BASF (A) provides written notice of its exercise of such right to Sterling within 30 Days after receipt of the notice from Sterling of its election to permanently shut down the Oxo Unit, (B) pays such amount to Sterling within 30 Days after delivery of such exercise notice to Sterling and (C) reimburses Sterling for all actual costs and expenses incurred in connection with decontaminating, dismantling, packing and transportation of such assets;

     (ii) Sterling will use commercially reasonable efforts to eliminate all costs associated with the Oxo Unit;

     (iii) any fixed costs associated with the Oxo Unit that could not be eliminated under clause (ii) above (estimated to be ***) shall, from and after the Exercise Date, be reallocated proportionately across all operating units at the Site, including the Esters Unit and the PA Unit; and

     (iv) any additional costs for storage and handling of delivered Oxo-Alcohols used by the Esters Unit shall, from and after the Exercise Date, be allocated to the Esters Unit;

provided, however, that the Threshold Fixed Costs Amount shall be increased by an amount equal to any costs allocated to the Esters Unit or the PA Unit pursuant to clause (iii) or clause (iv) above, such costs shall be excluded from any calculation of Cost Savings and the portion of the Allocated Fixed Costs Amount pertaining to each relevant General Category of Allocated Fixed Costs shall be increased by the applicable portion of such costs.

Article III

Payments; Capital Expenditures

          Section 3.01. Option Price for Early Termination of Oxo Unit; Profit Sharing Payment. (a) In addition to the other amounts payable by BASF under this Agreement, BASF shall pay Sterling the Oxo Unit Termination Option Payment in three installments, (i) an initial installment of *** due and payable on or before December 31, 2005, (ii) a second installment of *** due and payable on January 31, 2006 and (iii) a third installment of *** due and payable on December 1, 2006. The Parties acknowledge and agree that BASF shall be obligated to pay all three installments of the Oxo Unit Termination Option Payment, irrespective of whether or not BASF elects to exercise its rights under Section 2.09 and, if BASF does exercise its rights under Section 2.09, irrespective of whether such exercise is prior to, at the time of or after any such installment becomes due and payable.

          (b) On the Effective Date, BASF, at its sole cost and expense, shall conduct a full physical inventory of all Products, Raw Materials and Ancillary Raw Materials associated with the Existing Agreement that are on hand at the Site and a physical inventory of all Products associated with the Existing Agreement that are at terminals, in route and elsewhere. On or before January 23, 2006, BASF shall pay Sterling an amount equal to (i) Sterling’s accrued Profit (as defined in the Existing Agreement) as of December 31, 2005 plus (ii) *** of the estimated Profit to be derived from the sale of finished goods inventories of Products on hand as of December 31, 2005 (based upon average market prices for Products, average freight costs and actual inventory costs for December 2005), to the extent such amounts have not already been paid by BASF to Sterling. On or before January 23, 2006, BASF shall render a statement to Sterling showing the calculation of Profit for the final Year of the Existing Agreement (i.e., 2005) and Sterling’s share of such Profit under the Existing Agreement. Sterling may, if it desires, in good faith contest the validity or amount of any matter shown in such statement; provided, however, that Sterling provides BASF with written notice of such contest within three Months after receipt of the final Profit statement from BASF. Upon reasonable request, BASF shall provide Sterling access to all records pertaining to the calculation of such Profit, which records shall be subject to audit by an independent certified public accounting firm reasonably acceptable to BASF at any reasonable time within three months following receipt by Sterling of the final statement. Any audit will be at Sterling’s expense. Sterling shall enter into a written confidentiality agreement with any such auditing firm pursuant to which the auditing firm will agree to maintain the confidentiality of BASF’s accounts and records, and agree not to disclose proprietary information about BASF. Sterling will use commercially reasonable efforts to cause BASF to be a third party beneficiary of the nondisclosure and nonuse obligations contained in such confidentiality agreement. The auditor will either verify the correctness of BASF’s accounts and records or advise both Parties of the composite adjustments required to correct discrepancies for the period audited. Should it be determined that any additional amount of Profit is due and owing to Sterling, BASF shall immediately pay such part to Sterling, with interest thereon to the date of payment at the Applicable Interest Rate. Should it be determined that BASF paid Sterling an excess amount of Profit, Sterling shall immediately refund such excess amount to BASF to correct such overpayment. Payment or acceptance of any payment by Sterling shall not prejudice the right of Sterling to dispute or question the correctness thereof. Except as specifically set forth in this paragraph (b), no adjustments shall be made to such statement, and neither Party shall be required to pay or refund any amount to the other Party with respect to Sterling’s accrued Profit as of the date of this Agreement or the estimated Profit to be derived from the sale of inventories of Products on hand as of the date of this Agreement, irrespective of whether the amount shown in such statement thereafter is shown to have been incorrect.

          (c) Sterling shall pay BASF the remaining balance owing for the Switch Condenser Project at the same times and in the same amounts as would have been paid under the Existing Agreement.

          (d) On the Effective Date, BASF shall pay Sterling an amount equal to the remaining unamortized amount of charges for catalyst under the Existing Agreement and reimburse Sterling for the cost of existing inventory of fresh, uncharged catalyst.

          Section 3.02. Payments. (a) On or before January 1, 2006, BASF shall pay *** to Sterling as a prepayment towards certain Fixed Costs. Except as otherwise provided in this paragraph (a), such prepayment shall not be applied towards the payment of any invoice issued to BASF pursuant to this Agreement other than the invoice for Fixed Costs for the final Month of this Agreement (with any excess being refunded by Sterling to BASF on or before 15 Days after the termination of this Agreement). Under no circumstances shall any interest be payable to BASF by Sterling on the *** prepayment (unless Sterling wrongfully refuses to apply such amount towards the final Fixed Costs invoice or refund any excess). In the event that BASF fails to pay any undisputed invoice hereunder within five Business Days after receipt of written notice from Sterling of such delinquent payment, Sterling shall apply all or any portion of such prepayment towards the payment of such invoice and, if BASF fails to replenish the prepayment fund within five Business Days after receiving written notice from Sterling of any such application, Sterling shall be entitled to immediately cease all production of Products at the Plasticizers Complex and withhold shipment of any Products until such time as BASF replenishes the *** prepayment fund through the payment of such invoice in full, and Sterling shall not have any liability whatsoever to BASF as a result of such cessation of production and shipping.

          (b) Sterling shall, within 15 Days after the end of each Month, submit an invoice to BASF (an “Invoice”) showing (i) the quantity of each Product produced during the immediately preceding Month, (ii) the amount of Fixed Costs and Variable Costs incurred during such Month, (iii) the amount of Capital Expenditures and Expansion Capital Expenditures made during such Month and (iv) any other amounts due Sterling at that time pursuant to Section 3.04. Except as otherwise provided in Section 3.09(b), BASF shall pay each Invoice on or before the 15th Day after receipt thereof (or if such Day is not a Business Day, then on the next Business Day), irrespective of whether any Products were produced in such Month; provided, however, that if no Products are produced in any Month, Sterling will use reasonable efforts to minimize the amount of Variable Costs incurred during such Month. Notwithstanding anything to the contrary contained in this Agreement, if, in any Year, Sterling’s cost of providing the engineering services referred to in the Engineering General Category of Allocated Fixed Costs exceed the amount attributable to such General Category of Allocated Fixed Costs in the calculation of the Allocated Fixed Costs Amount for such Year, Sterling may, in its sole discretion, cease providing engineering services pursuant to this Agreement in such Year unless and until BASF agrees in writing to reimburse Sterling for the cost of all such engineering services in such Year.

          (c) As of the date of this Agreement, each of the Esters Unit and the PA Unit have rated annual production capacities in excess of the Capacity for such Unit. Sterling shall, at BASF’s sole cost and expense, perform such work (including engineering work) as is required to convert each of the Units to produce Products at the Capacity for such Products and convert Sterling’s existing Oxo-Alcohols storage tanks from manufactured Oxo-Alcohols service to delivered Oxo-Alcohols service (the “Plasticizers Complex Reconfiguration”), and (i) BASF shall reimburse Sterling for such costs and expenses on the same basis as BASF is required to reimburse Sterling for Variable Costs under paragraph (b) above and (ii) to the extent such costs and expenses are Allocated Fixed Costs, shall be paid separately from, and in addition to, the

Allocated Fixed Costs Amount; provided, however, that Sterling shall be solely responsible for the first *** of costs and expenses incurred in connection with such conversion of the existing Oxo-Alcohols storage tanks.

          (d) From and after the Commissioning Date, if the aggregate Fixed Costs charged by Sterling for the Esters Unit and the PA Unit in any Year (excluding catalyst amortization, maintenance turnaround expense and any severance costs connected with either of such Units paid by BASF pursuant to Section 3.06(e)) (the “Component Fixed Costs”) exceed the Threshold Fixed Costs Amount by more than ***, BASF may elect to terminate this Agreement; provided, however, that:

     (i) no such termination will be effective unless BASF has given written notice to Sterling of its election to terminate this Agreement within 30 Days after the end of such Year;

     (ii) such termination will become effective on the date specified in such notice (which may not be prior to 12 months after the date of receipt of such notice by Sterling) or, if no such date is specified, 12 months after the date on which such notice is received by Sterling; and

     (iii) BASF pays Sterling the applicable Early Termination Fee on the effective date of the termination of this Agreement, as determined under clause (ii) above, provided, however, that:

	(A)		if the Component Fixed Costs for such Year exceed the greater of the Threshold Fixed Costs Amount and the actual Fixed Costs for the first full Year after the Commissioning Date by at least *** but less than ***, the applicable Early Termination Fee shall be reduced by an amount equal to ***;
	(B)		if the Component Fixed Costs for such Year exceed the greater of the Threshold Fixed Costs Amount and the actual Fixed Costs for the first full Year after the Commissioning Date by at least *** but less than ***, the applicable Early Termination Fee shall be reduced by an amount equal to ***; and
	(C)		if the Component Fixed Costs for such Year exceed the greater of the Threshold Fixed Costs Amount and the actual Fixed Costs for the first full Year after the Commissioning Date by at least ***.

For purposes of determining whether BASF has the right to terminate this Agreement as provided above, (x) if the Commissioning Date is on or before June 30 of a Year, the first Year shall be the period from the Commissioning Date through December 31 of that Year, in which event the Threshold Fixed Costs Amount shall be pro rated based on the number of Days left in such Year as of the Commissioning Date, and (y) if the Commissioning Date is after June 30 of a Year, the first Year shall begin on January 1 of the next Year. Notwithstanding anything to the contrary in this paragraph (d), in the event that (1) BASF provides Sterling with a written notice of its election to terminate this Agreement and (2) Sterling, by providing written notice to BASF within 30 Days

after its receipt of the termination notice from BASF, elects to cap BASF’s reimbursement obligation for Component Fixed Costs for such Year at the Threshold Fixed Costs Amount, then such termination notice from BASF shall be null and void and of no further force or effect. In such event, Sterling shall reimburse BASF for any Component Fixed Costs previously paid by BASF in excess of the Threshold Fixed Costs Amount in that Year and BASF shall not be required to reimburse Sterling for any Component Fixed Costs beyond the Threshold Fixed Costs Amount for that Year that remain unpaid.

          Section 3.03. Facility Fees. In addition to the other amounts payable by BASF under this Agreement, on the first Day of each Quarter, commencing with the Quarter commencing on the Effective Date, BASF shall pay Sterling the Facility Fees for such Quarter. Except to the extent otherwise provided in Section 4.04, each of the Facility Fees shall be payable in full irrespective of whether any production occurs at any of the Units during such Quarter or the level of production at any of the Units during such Quarter; provided, however, that if Sterling fails (unless such failure is excused pursuant to Section 6.02 or is caused by a breach of the Agreement by BASF) to maintain the production capacity of the Esters Unit or the PA Unit over any period of at least *** consecutive Days at a level of at least *** (in the case of Esters) or at least *** (in the case of PA) of the relevant Monthly Contract Capacity and, in either case, BASF requires production in excess of the available capacity, then the Esters Facility Fee or the PA Facility Fee, as applicable, shall be reduced for each Quarter (or portion thereof) that Sterling so fails to maintain the Monthly Contract Capacity. In such cases, the relevant Facility Fee payable for such Quarter shall be determined by (a) dividing the relevant Facility Fee by 90 to determine the amount of such Facility Fee payable for each Day during such Quarter, (b) reducing the amount determined under clause (a) for each Day during such Quarter when Sterling so failed to maintain the Monthly Contract Capacity for the relevant Product by multiplying such amount by the Reduction Factor applicable to such Day and (c) deducting the aggregate reductions under clause (b) for such Quarter from the Facility Fee otherwise payable for such Quarter. If the Facility Fee for any Quarter is reduced pursuant to this Section 3.03 after BASF has paid such Facility Fee, BASF may deduct the amount overpaid from the next Facility Fee payable hereunder or, if no further Facility Fees are payable hereunder, Sterling shall refund such amount to BASF within 15 Days after receipt of an invoice therefore from BASF.

          Section 3.04. Capital Expenditures and Expansion Capital Expenditures. (a) At least 30 Days prior to the Quarterly Meeting to be held in October of each Year, Sterling shall submit to BASF a capital budget, prepared by Sterling in good faith and upon realistic assumptions, for the next succeeding Year (each, a “Capital Budget”) for those Capital Projects that ▇▇▇▇▇▇▇▇ ▇▇▇▇▇ necessary (i) to maintain the reliable and safe operation of the PA Unit and the Esters Unit at Capacity, (ii) until the Oxo Unit Termination Date, to maintain the reliable and safe operation of the Oxo Unit at Capacity, and (iii) to maintain the Plasticizers Complex in compliance with all applicable Laws and permits. The Capital Budget for 2006 is attached hereto as Exhibit F. Each Capital Budget shall include a description of each Capital Project in reasonable detail and an estimate of the Capital Expenditures anticipated to be made in connection with such Capital Project. Prior to commencing any Capital Project, Sterling shall, to the extent practicable under the circumstances, consult with BASF and give BASF the opportunity to comment on such proposed Capital Project or propose alternative

approaches to such Capital Project; provided, however, that (A) except as otherwise provided in paragraph (b) below, in the event that Sterling and BASF disagree on whether a Capital Project should be pursued or on the approach to any Capital Project, *** and (B) except as otherwise specifically provided in this Agreement, BASF shall not be liable to Sterling for any Damages directly or indirectly arising out of Sterling’s use or implementation of BASF’s comments to such Capital Project. In addition, in the event of an emergency, Sterling may conduct Capital Projects and make Capital Expenditures, irrespective of whether or not any such Capital Project was included in any previous Capital Budget, if Sterling, in its sole discretion, deems such Capital Project and Capital Expenditures necessary to maintain the Plasticizers Complex in accordance with the standards provided in this paragraph (a) or the standard of care described in Section 4.01; provided, however, that Sterling shall inform BASF via facsimile or E-Mail of the nature of the emergency and the expected expenditures within 72 hours after it makes such determination. BASF shall reimburse Sterling for *** of all Capital Expenditures made for each Capital Project. In the event that Sterling’s engineering services are required in connection with any Capital Project or Expansion Project, Sterling shall provide such engineering services at BASF’s sole cost and expense, and such engineering services shall not be considered as being among the engineering services referred to in the Allocated Fixed Costs Table.

          (b) Notwithstanding anything to the contrary contained in this Section 3.04, during the period commencing on January 1, 2011 and continuing thereafter until the expiration or termination of this Agreement, BASF shall have the right to elect to not proceed with any Capital Project the primary purpose of which is to maintain the reliable operation of any Unit at Capacity; provided, however, that BASF elects to not renew this Agreement for an Additional Term prior to January 1, 2011 and, provided further, that if BASF elects to not proceed with any such Capital Project, Sterling shall have the option to either:

     (i) proceed with such Capital Project, in which event BASF shall reimburse Sterling for, (A) if such Capital Project was initially submitted for approval at any time before January 1, 2011, *** of the actual Capital Expenditures made to complete such Capital Project, (B) if such Capital Project was initially submitted for approval at any time on or after January 1, 2011 but before January 1, 2012, *** of the actual Capital Expenditures made to complete such Capital Project, or (C) if such Capital Project was initially submitted for approval at any time on or after January 1, 2012 but before January 1, 2013, *** of the actual Capital Expenditures made to complete such Capital Project, in each case, irrespective of whether such Capital Expenditures are made during the Year used to determine the applicable percentage of reimbursement and irrespective of whether such Capital Expenditures are made prior to or after the expiration of this Agreement (but excluding any Capital Expenditures made on or after January 1, 2014); or

     (ii) not proceed with such Capital Project, in which event BASF shall make a one-time payment to Sterling in an amount equal to (A) if such Capital Project was initially submitted for approval at any time before January 1, 2011, *** of the estimated Capital Expenditures required to complete such Capital Project, (B) if such Capital Project was initially submitted for approval at any time

on or after January 1, 2011 but before January 1, 2012, *** of the estimated Capital Expenditures required to complete such Capital Project, or (C) if such Capital Project was initially submitted for approval at any time on or after January 1, 2012 but before January 1, 2013, *** of the estimated Capital Expenditures required to complete such Capital Project; provided, however, that if BASF disputes the necessity of any such Capital Project or the estimated Capital Expenditures required to complete any such Capital Project, such dispute shall be resolved in accordance with the dispute resolution procedures set forth in Section 8.09.

Any payments made by BASF pursuant to this paragraph (b) shall be excluded from the obligation of Sterling to reimburse BASF for undepreciated capital pursuant to paragraph (e) below.

          (c) At any time during the term of this Agreement, BASF may, at its option and at its sole cost and expense, (i) elect to increase the Capacity of the PA Unit through the installation of new switch condensers (the “New Switch Condenser Project”) and (ii) elect to use all or any portion of the incremental PA to produce additional Esters or sell all or any portion of the incremental PA in the merchant market. If BASF elects to sell all or any portion of the incremental PA in the merchant market, an additional PA storage tank would be installed at the Site. BASF shall be responsible for any and all Expansion Capital Expenditures and other costs associated with the New Switch Condenser Project and the installation of any additional storage tanks required in connection with the storage and shipping of the resulting additional PA, and, to the extent such costs and expenses are Allocated Fixed Costs, shall be paid separately from, and in addition to, the Allocated Fixed Costs Amount. Upon commissioning of any of the switch condensers under the New Switch Condenser Project, the PA Facility Fee shall be increased to an amount equal to the PA Facility Fee then in effect times a fraction, the numerator of which is the expected Capacity of the PA Unit following the New Switch Condenser Project and the denominator of which is the Capacity of the PA Unit immediately prior to the commissioning of any of the switch condensers under the New Switch Condenser Project.

          (d) At any time during the term of this Agreement, BASF may, at its option and at its sole cost and expense, elect to increase the Capacity of the PA Unit or the Esters Unit through Expansion Projects other than the New Switch Condenser Project. BASF shall be responsible for any and all Expansion Capital Expenditures and other costs associated with each such Expansion Project and, to the extent such costs and expenses are Allocated Fixed Costs, shall be paid separately from, and in addition to, the Allocated Fixed Costs Amount; provided, however, that any payments made to Sterling by BASF for Expansion Capital Expenditures under this paragraph (d) shall be excluded from the obligation of Sterling to reimburse BASF for undepreciated capital pursuant to paragraph (e) below. BASF shall also be responsible for any and all Fixed Costs directly attributable to the increased Capacity of the PA Unit or the Esters Unit by virtue of any Expansion Project and (i) the Threshold Fixed Costs Amount shall be increased by the aggregate amount of such Fixed Costs and (ii) to the extent such costs and expenses are Allocated Fixed Costs, the portion of the Allocated Fixed Costs Amount pertaining to each relevant General Category of Allocated Fixed Costs shall be increased by the applicable portion of such costs and expenses. Upon mechanical

completion of any Expansion Project, the PA Facility Fee or the Esters Facility Fee, as applicable, shall be increased as provided in the definition of PA Facility Fee or Esters Facility Fee, as applicable.

          (e) Subject to Section 7.01(d), within 90 Days after the expiration or termination of this Agreement, Sterling shall pay BASF an amount equal to the undepreciated capital paid by BASF for each Capital Project (excluding any amounts paid by BASF pursuant to paragraphs (b) or (d) above), based on a straight line, *** life, mid-year convention depreciation as defined by the U.S. Federal Income Tax Code, calculated from the completion date of each relevant Capital Project; provided, however, that:

     (i) if (A) BASF elects to terminate this Agreement pursuant to Section 3.02(d), (B) either Party elects to terminate this Agreement pursuant to Section 6.02(e) or (C) Sterling elects to terminate this Agreement pursuant to Section 7.01(c) based on a breach by BASF of any material covenant, agreement, term, provision or condition of this Agreement, the amount of undepreciated capital paid by BASF for all Capital Projects shall be deemed to be zero and no amount shall be payable by Sterling to BASF pursuant to this paragraph (e);

     (ii) if BASF elects to terminate this Agreement pursuant to Section 7.01(b), (A) the amount of undepreciated capital shall be the lower of (x) the amount of the applicable Early Termination Fee and (y) the amount of undepreciated capital that would have existed on December 31, 2013 if this Agreement had continued until that date and (B) on each anniversary of the actual date of termination of this Agreement, Sterling shall pay BASF an amount equal to the depreciation of such capital that would have been recognized during the immediately preceding 12-month period (using the *** depreciation schedule described above) if the first such payment had occurred on December 31, 2014 until such time as the total amount payable by Sterling under clause (A) above has been paid in full;

     (iii) if BASF elects to terminate this Agreement pursuant to Section 7.01(c) based on a breach by Sterling of any material covenant, agreement, term, provision or condition of the Agreement, Sterling shall pay BASF an amount equal to such undepreciated capital as of the date of termination within 30 Days after the date of such termination; and

     (iv) if either Party elects to terminate this Agreement pursuant to Section 4.04(e), the amount of undepreciated capital payable to BASF in connection with the termination of this Agreement shall be determined pursuant to that Section.

In the event that Sterling fails to pay any amount when due under this paragraph (e), such amount shall bear interest at the Applicable Interest Rate, accruing each Day from the Day such amount was originally due until the Day such amount is paid in full.

          Section 3.05. Maintenance Expenditures. At least 30 Days prior to the Quarterly Meeting to be held in October of each Year, Sterling shall submit to BASF a maintenance expense budget, prepared by Sterling in good faith and upon realistic

assumptions, for the next succeeding Year (each, a “Maintenance Budget”) for such maintenance as Sterling determines is required to maintain the Plasticizers Complex in accordance with the standard of care described in Section 4.01. Sterling shall provide BASF with monthly reports regarding maintenance expenses. Unless otherwise agreed by the Parties, all maintenance expenses shall be included in Fixed Costs for purposes of this Agreement.

          Section 3.06. Cost Savings; Manpower Reductions. (a) The Parties shall cooperate in investigating, evaluating and implementing mutually agreeable methods to reduce Fixed Costs, Variable Costs, Capital Expenditures and Expansion Capital Expenditures. On or before January 31 of each year, commencing with January 31, 2006, Sterling shall submit a statement to BASF showing in reasonable detail any reductions in Fixed Costs or Variable Costs (“Cost Savings”) achieved in the immediately preceding calendar year compared to the Fixed Costs in the Maintenance General Category, the Fixed Costs in the Materials Handling General Category and the Variable Costs for such Unit incurred when such costs were at there lowest in any calendar year after 2003 and the Fixed Costs in the Personnel General Category and the Fixed Costs in the Other Direct General Category for such Unit incurred during 2005; provided, however, that:

     (i) for purposes of determining whether any Cost Savings attributable to PPI Adjusted Fixed Costs were achieved in any Year, the aggregate amount of PPI Adjusted Fixed Costs incurred in the earlier period shall be adjusted as of December 31 of each year after such PPI Adjusted Fixed Costs were actually incurred by the PPI Factor for such subsequent year (e.g., if PPI Adjusted Fixed Costs incurred in 2008 were being compared to PPI Adjusted Fixed Costs incurred in 2006, the PPI Adjusted Fixed Costs incurred in 2006 would be adjusted based on the PPI Factor for 2007 and adjusted again based on the PPI Factor for 2008);

     (ii) the amounts shown in each such statement shall be split into the General Categories of Fixed Costs and Variable Costs and Cost Savings shall be determined for each General Category of Fixed Costs and each General Category of Variable Costs independently;

     (iii) the Variable Costs for each calendar year shall be based on per pound usages for each component of Variable Costs with the Cost Savings derived from any improvements in usages being calculated using current market prices at the time of determination;

     (iv) the per pound usages for each component of Variable Costs for 2004 are specified on Exhibit B; provided, however, that irrespective of actual per pound usage in 2004, the per pound usage for *** in 2004 shall be deemed to be *** pounds of *** per pound of PA; and

     (v) once the Plasticizers Complex Reconfiguration is completed, the initial per pound usages of each component of Variable Costs for the Esters Unit will be determined under paragraph (c) below.

Each statement delivered by Sterling shall set forth (A) the amount of Fixed Costs in each General Category of direct Fixed Costs during the immediately preceding year, (B) the amount of Variable Costs in each General Category of Variable Costs during the immediately preceding year, (C) the amount of Fixed Costs in each of the Maintenance General Category and the Materials Handling General Category when the Fixed Costs in that General Category were at their lowest in any calendar year after 2003, (D) the amount of Fixed Costs in each of the Personnel General Category and the Other Direct General Category for 2005, (E) the amount of Variable Costs in each General Category of Variable Costs for the Oxo Unit (through the Oxo Unit Termination Date) and the PA Unit when the Variable Costs in that General Category were at their lowest in any calendar year after 2003, and (F) the amount of Variable Costs in each General Category of Variable Costs for the Esters Unit when the Variable Costs in that General Category were at their lowest in any calendar year after 2003 (or, after the Commissioning Date, their lowest since the end of the year including the Commissioning Date), in each case, subject to the adjustments described above. For example, the statement delivered on or before January 31, 2009 will (1) compare the amount of Fixed Costs in the Maintenance General Category of Fixed Costs and the Materials Handling General Category of Fixed Costs (by General Category) in 2008 to the lowest amount of such Fixed Costs (by General Category) in any calendar year after 2003 (after the above-described adjustments), (2) compare the amount of Variable Costs (by General Category) for the Oxo Unit (through the Oxo Unit Termination Date) and the PA Unit in 2008 to the lowest amount of Variable Costs (by General Category) in any calendar year after 2003 (after the above-described adjustments), which may be different calendar years for different General Categories of Variable Costs, (3) compare the amount of Variable Costs (by General Category) for the Esters Unit in 2008 to the lowest amount of Variable Costs (by General Category) in any calendar year after 2003 (or, after the Commissioning Date, in any calendar year from and after the year including the Commissioning Date (after the above-described adjustments), which may be different calendar years for different General Categories of Variable Costs, and (4) compare the amount of Fixed Costs in the Personnel General Category of Fixed Costs and the Other Direct General Category of Fixed Costs (by General Category) in 2008 to the Fixed Costs in those General Categories in 2005 (after the above-described adjustments).

          (b) Within 15 Days after receipt of such statement, BASF will pay Sterling an amount equal to (i) *** of the amount by which the Fixed Costs included in the Maintenance General Category in the earlier calendar year shown in the statement exceed the Fixed Costs included in the Maintenance General Category in the later calendar year shown in such statement, plus (ii) *** of the amount by which the Fixed Costs included in the Materials Handling General Category in the earlier calendar year shown in the statement exceed the Fixed Costs included in the Materials Handling General Category in the later calendar year shown in such statement, plus (iii) *** of the amount by which the Fixed Costs included the Personnel General Category in 2005 exceed the Fixed Costs included the Personnel General Category in the later calendar year shown in such statement plus (iv) *** of the amount by which the Fixed Costs included the Other Direct General Category in 2005 exceed the Fixed Costs included the Other Direct General Category in the later calendar year shown in such statement plus (v) *** of the amount by which the per pound usage of any component of Variable Costs in the earlier calendar year shown in the statement exceeds the per pound usage of

such component of Variable Costs in the later calendar year shown in such statement times the average market price for such component of Variable Costs during the later calendar year shown in the statement. Sterling shall employ consistent accounting practices from year to year.

          (c) Notwithstanding anything to the contrary contained in this Section 3.06, the per pound usage of each component of Variable Costs for the Esters Unit for the Year in which the Commissioning Date occurs shall be deemed to be (i) the per pound usage of such component of Variable Costs experienced in the most recent full Month prior to the Commissioning Date during which the Esters Unit was not shut down at any time due to operational difficulties or (ii) such other per pound usage as the Parties shall mutually agree; provided, however, if the Parties fail to agree on an alternative per pound usage of any component of Variable Costs for the Esters Unit under this clause (ii) within 30 Days after the Commissioning Date, the per pound usage of such component of Variable Costs shall be the per pound usage determined under clause (i).

          (d) For purposes of calculating Cost Savings under this Section 3.06, if a Force Majeure Event results in the suspension of all or any of the operations at the Plasticizers Complex in any Month (whether in the current Year or any prior Year), the Fixed Costs and Variable Costs for such Month shall be deemed to be the same as the Fixed Costs and Variable Costs experienced in the most recent preceding full Month that was not affected by a Force Majeure Event.

          (e) In addition to the amounts (if any) payable by BASF hereunder for Cost Savings, in the event that any manpower reduction occurs at the Site, (i) BASF shall pay Sterling an amount equal to *** of the severance costs incurred in connection with such manpower reduction that will result in direct labor costs savings for the Plasticizers Complex and (ii) BASF shall pay Sterling its allocable portion of any severance costs incurred in connection with such manpower reduction that will result in lower allocated Fixed Costs for the Plasticizers Complex, such allocation to be based on the same percentages as are then used to allocate other allocated Fixed Costs to the Plasticizers Complex; provided, however, that any reduction in salaries and employee benefits resulting from any such manpower reduction shall be excluded from any subsequent comparisons of Fixed Costs and Variable Costs.

          (f) Notwithstanding anything to the contrary contained in this Section 3.06, if any Cost Savings are achieved in any Year due to a reduction in the Fixed Costs allocated to the Plasticizers Complex following the commissioning of a new operating unit at the Site, for purposes of any subsequent calculations of Cost Savings, each prior Year that benefited from such reduction in allocated Fixed Costs shall be calculated as if such reduction in Fixed Costs had not occurred. For example, if a *** reduction in the Maintenance General Category of Fixed Costs occurred due to such a reallocation in 2007 and in 2008 the amount of Fixed Costs in the Maintenance General Category also reflected such *** reduction, then, for purposes of calculating Cost Savings in 2009, the amount of Fixed Costs in the Maintenance General Category incurred in both 2007 and 2008 would be deemed to be *** higher than those actually incurred.

          (g) Notwithstanding anything to the contrary contained in this Agreement, the per pound usages of each component of Variable Costs shall be used solely for purposes of determining whether Sterling has achieved any Cost Savings in a given year and BASF shall pay the actual amounts of Variable Costs incurred during each Month.

          Section 3.07. Taxes. In addition to the other amounts payable by BASF under this Agreement, all sales, use and excise taxes and other taxes and similar charges which Sterling may be required to pay and which are levied directly upon the receipt or storage by Sterling of Raw Materials, the production or storage of Products or the sale or delivery of Products hereunder (including any “Superfund” tax and any other environmental tax or like charge assessed or imposed by any Governmental Authority but excluding franchise tax or any tax levied against the income or gross receipts of Sterling) shall be paid by BASF (or if paid by Sterling, reimbursed by BASF within 15 Days after receipt of an invoice therefore, or if such Day is not a Business Day, then on the next Business Day).

          Section 3.08. Wire Transfers, Etc. All sums and amounts payable under this Agreement shall be paid in United States dollars by wire transfer or electronic funds transfer of immediately available funds to such bank or account in the continental United States for the account of the payee as from time to time the payee shall have directed to the payor in writing (or, if no such direction shall have been given, by check of the payor payable to the order of the payee and mailed to the payee in the manner and at the address set forth in Section 8.01). Whenever in this Agreement BASF is required to pay or reimburse Sterling upon receipt of invoice, or otherwise when no due date for payment is specifically provided, payment shall be due as provided in Section 3.02(b) and shall be made in the manner set forth in this Section 3.08.

          Section 3.09. Late Payments. (a) In the event that either Party fails to pay any amount when due hereunder, such amount shall bear interest at the Applicable Interest Rate, accruing each Day from the Day such amount was originally due until the Day such amount is paid in full. With respect to any delinquent payment by BASF, unless such amount is the subject of a good faith dispute between the Parties pursuant to paragraph (b) below, Sterling shall have the rights provided in Section 3.02(a). Sterling may exercise its rights under Section 3.02(a), and either Party may exercise its rights under this paragraph (a), at any time and from time to time during the continuance of this Agreement.

          (b) Notwithstanding anything to the contrary contained in paragraph (a) above, BASF may, in good faith, contest the validity or amount of any amount included in any invoice submitted by Sterling pursuant to this Article III, and may defer the payment of any contested portion thereof during the pendency of such contest without defaulting under this Agreement; provided, however, that BASF gives written notice to Sterling of its contest of such amount prior to the time the relevant invoice is due and payable. In the event that BASF withholds the payment of any contested amount and it is ultimately determined that such amount is due and payable to Sterling, BASF shall pay such amount to Sterling immediately after such determination, together with interest thereon at the Applicable Interest Rate accruing each Day from the Day such amount was originally due until the Day such amount is paid in full. Payment of any amount under this Article III shall not prejudice the right of BASF to dispute or

question the correctness thereof so long as BASF notifies Sterling that it is contesting the correctness of such amount prior to its payment thereof.

Article IV

Operation of the Plasticizers Complex and Related Matters

          Section 4.01. Operational Practices. Sterling shall operate and maintain the Plasticizers Complex and perform its other obligations hereunder, including material handling and distribution, using operating procedures equivalent to or better than (a) the standard of care it uses in operating and conducting manufacturing at the Plant and performing obligations for its own account and (b) the standard of care a prudent operator would use in operating and manufacturing at a unit similar to the Plasticizers Complex. Subject to the terms and conditions of this Agreement, Sterling shall operate the Plasticizers Complex in a manner designed to fulfill its obligations to deliver Products hereunder that meet the Product Specifications in accordance with the Estimated Delivery, Shipment and Storage Instructions, the Delivery, Shipment and Storage Instructions and any additional delivery, shipment and storage instructions issued by BASF pursuant to Section 2.01(b); provided, however, that such operational practices do not violate this Agreement or any applicable Law and are not inconsistent with the prudent operation of the Plasticizers Complex. Except for amounts being contested in good faith, Sterling shall pay, as they become due, all costs and expenses incurred to trade creditors in the operation of the Plasticizers Complex which, if remaining unpaid, might become a Lien on the Plasticizers Complex.

          Section 4.02. Plant Visits; BASF Liaison. (a) Sterling shall grant BASF personnel access to the Plasticizers Complex at reasonable times and on reasonable notice; provided, however, that such visits are consistent with Sterling’s contractual obligations under licenses or sublicenses to which it is a party. BASF shall cause all of its personnel to comply with Sterling’s safety and reasonable confidentiality procedures and policies.

          (b) BASF would have the option, at its sole cost and expense, to appoint a liaison person (the “BASF Liaison”) for the Plasticizers Complex, and the BASF Liaison would be entitled to make recommendations to Sterling regarding the maintenance, upkeep and operations of the Plasticizers Complex; provided, however, that Sterling would not be under any obligation to adopt or implement any recommendations made by the BASF Liaison that Sterling, in its sole discretion, believes may adversely affect the health, safety or environmental performance of the Plasticizers Complex or may increase Sterling’s costs to operate or maintain the Plasticizers Complex. If Sterling does not wish to adopt or implement any recommendation made by the BASF Liaison solely because Sterling believes that such adoption or implementation may increase Sterling’s costs to operate or maintain the Plasticizers Complex, Sterling shall adopt or implement such recommendation but (i) any increase in costs resulting from such adoption or implementation shall be paid by BASF, (ii) the Threshold Fixed Costs Amount shall be increased by the amount of such costs, (iii) such costs shall be excluded from any calculation of Costs Savings and (iv) to the extent such costs and expenses are Allocated Fixed Costs, the portion of the

Allocated Fixed Costs Amount pertaining to each relevant General Category of Allocated Fixed Costs shall be increased by the applicable portion of such costs and expenses. Sterling would provide the BASF Liaison with office space at the Site and grant the BASF Liaison access to the Plasticizers Complex at all reasonable times to observe and inspect, and to perform safety, manufacturing and quality studies; provided, however, that such activities do not materially disrupt the operation of the Plasticizers Complex or Sterling’s other operations at the Site.

          Section 4.03. Insurance. During the term of this Agreement, Sterling shall maintain property damage and liability insurance on the Plasticizers Complex and those parts of the Plant which serve the Plasticizers Complex in types and amounts, and against such risks, substantially similar to those carried and insured against as of the date of this Agreement; provided, however, that in any event Sterling shall not be required to maintain business interruption or terrorism insurance coverages. BASF shall reimburse Sterling for any amounts paid by Sterling that are credited towards the deductible under Sterling’s liability insurance policy or property damage/business interruption policy to the extent the underlying event (a) is directly related to the Plasticizers Complex, any Raw Material, Ancillary Raw Material or Product or any other matter under this Agreement and (b) Sterling is not required to indemnify BASF for such underlying event pursuant to Section 6.01(a). Any payments required to be made by BASF pursuant to this Section 4.03 (i) shall be made by BASF within 15 Days after receipt of an invoice therefore from Sterling, or if such Day is not a Business Day, then on the next Business Day, (ii) shall be excluded from any calculation of Costs Savings or the Threshold Fixed Costs Amount under this Agreement and (iii) to the extent such costs and expenses are Allocated Fixed Costs, shall be paid separately from, and in addition to, the Allocated Fixed Costs Amount. BASF may carry additional insurance, at its sole discretion and cost.

          Section 4.04. Damage or Destruction. (a) If, at any time during the term of this Agreement, if all or any part of the Plasticizers Complex or any Dependent Facility is damaged or destroyed by fire explosion, flood, hurricane, windstorm or other casualty of any kind or nature (including any insured or uninsured casualty), ordinary or extraordinary, foreseen or unforeseen, Sterling shall either (i) at its sole cost and expense, and irrespective of whether the insurance proceeds, if any, are sufficient for such purpose, within *** Days after the date of such damage or destruction, commence repairing, altering, restoring, replacing or rebuilding the Plasticizers Complex or such Dependent Facility to substantially the same condition as existed immediately prior to such damage or destruction, and thereafter continue with such work with reasonable diligence, or (ii) elect, by providing BASF with written notice of such election within *** Days after the date of such damage or destruction, not to repair, alter, restore, replace or rebuild the Plasticizers Complex or such Dependent Facility.

          (b) If Sterling elects to repair, alter, restore, replace or rebuild the Plasticizers Complex or such Dependent Facility, (i) Sterling shall have the right to require that all insurance proceeds from policies maintained by Sterling and BASF providing coverage for the relevant casualty be applied to the payment of all costs and expenses related thereto, and (ii) the Parties’ respective obligations under this Agreement shall continue, but Sterling shall bear all costs of such repair in excess of the proceeds of insurance and shall have the right to fully depreciate such repair costs.

          (c) If Sterling elects not to repair, alter, restore, replace or rebuild the Plasticizers Complex or such Dependent Facility, BASF may elect, at its sole cost and expense, to pay the cost to repair, alter, restore, replace or rebuild the Plasticizers Complex or such Dependnent Facility; provided, however, that BASF exercises such right within 120 Days following receipt of written notice of Sterling’s election not to do so and, provided further, that, notwithstanding any such payment, BASF shall not acquire any right, title or interest in or to the Plasticizers Complex or such Dependent Facility. If BASF exercises such election, Sterling shall apply all insurance proceeds from policies maintained by Sterling that provided coverage for the relevant casualty to the payment of all costs and expenses related to such repair, alteration, restoration, replacement or rebuilding.

          (d) In the event that all or any portion of the Plasticizers Complex or any Dependent Facility is damaged or destroyed after the Effective Date by fire or other casualty, and either (i) neither Party has elected to repair, alter, restore, replace or rebuild the Plasticizers Complex, such Dependent Facility or relevant portion thereof or (ii) Sterling has elected to repair, alter, restore, replace or rebuild the Plasticizers Complex, such Dependent Facility or relevant portion thereof but has not begun to repair, alter, restore, replace or rebuild the Plasticizers Complex, such dependent Facility or relevant portion thereof within six months following such damage or destruction (or at any time thereafter fails to use reasonable efforts to continue to repair, alter, restore, replace or rebuild the Plasticizers Complex, such Dependent Facility or relevant portion thereof), then each of the Facility Fees shall be reduced for each Quarter, or portion thereof, during which Sterling fails to maintain the Monthly Contract Capacity for any related Products. In such cases, the relevant Facility Fee payable for each such Quarter shall be determined by (A) dividing the relevant Facility Fee by 90 to determine the amount of such Facility Fee payable for each Day during such Quarter, (B) reducing the amount determined under clause (A) for each Day during such Quarter when Sterling so failed to maintain the Monthly Contract Capacity for the relevant Product by multiplying such amount by the Reduction Factor applicable to such Day and (C) deducting the aggregate reductions under clause (B) for such Quarter from the Facility Fee otherwise payable for such Quarter. If the Facility Fee for any Quarter is reduced pursuant to this paragraph (d) after BASF has paid such Facility Fee, BASF may deduct the amount overpaid from the next Facility Fee payable hereunder or, if no further Facility Fees are payable hereunder, Sterling shall refund such amount to BASF within 15 Days after receipt of an invoice therefore from BASF.

          (e) If neither Party elects to repair, alter, restore, replace or rebuild the Plasticizers Complex, such Dependent Facility or the relevant portion thereof and the damage or destruction involves more than *** of the Plasticizers Complex or causes the Plasticizers Complex to be incapable of producing Products at greater than *** of Capacity, either Party may terminate this Agreement on 30 Days’ prior written notice to the other Party and BASF may cease paying the Facility Fees after the occurrence of the relevant damage or destruction. In the event of any such termination of this Agreement, the amount of undepreciated capital paid by BASF for all Capital Projects shall be deemed to be an amount equal to the lesser of (i) the amount of such undepreciated capital as of the date of such damage or destruction and (ii) the amount recovered by Sterling under its insurance policies attributable to the damage to or destruction of the

Plasticizers Complex minus the portion of the deductible under such insurance policies attributable to such damage to or destruction of the Plasticizers Complex times a fraction, the numerator of which is the amount of such undepreciated capital and the denominator of which is the value of the Plasticizers Complex prior to such damage or destruction.

          Section 4.05. Hazards. Each Party acknowledges that Ancillary Raw Materials, Raw Materials and Products may be, or become, considered Hazardous Materials, and that it is familiar with the hazards of Ancillary Raw Materials, Raw Materials and Products, their respective applications and the containers in which they are shipped. Each Party shall inform and train its employees and customers with respect to all such hazards. In addition, Sterling shall (a) warn all persons at the Plant, including its employees, agents and invitees, of the health and environmental hazards associated with Ancillary Raw Materials, Raw Materials and Products, their respective applications and the containers in which they are shipped (including proper disposal methods), (b) advise all such persons at the Plant who handle or might otherwise come into contact with such materials of all applicable precautions and safety measures to be employed at the Plant when handling or storing such materials and (c) cause such precautions and safety measures to be employed at the Plant in accordance with all safety, health and environmental regulations.

          Section 4.06. Compliance with Laws. Nothing in this Agreement is intended to, or shall be deemed or construed as being intended to, authorize or require Sterling to violate any Law (including any Environmental Law). Each Party shall comply with all Laws (including Environmental Laws) applicable to the Parties, the transactions contemplated by this Agreement or the preservation of public or Plant health or safety, including the Occupational Safety and Health Act of 1970, and the regulations issued thereunder, as the same may be amended from time to time. In accordance with the foregoing provision, but not by way of limitation, it is specifically understood that BASF is an Equal Opportunity Employer and Sterling warrants that Sterling complies with the Fair Labor Standard Act of 1938, as amended. Sterling agrees that, if this Agreement is construed to be a subcontract within the meaning of the Rules and Regulations approved by the United States Secretary of Labor pursuant to Executive Order 11246, as amended, the Vietnam Era Veterans Readjustment Assistance Act of 1974, as amended, or the Rehabilitation Act of 1973, as amended, or of the regulations issued pursuant to Executive Order 11625, the provisions of the applicable regulations as well as the Equal Opportunity and Nondiscrimination provision of Section 202 of Executive Order 11246 shall be incorporated herein by reference and shall be binding upon Sterling as part of this Agreement. Sterling shall label and placard all shipments of Products in compliance with all applicable Laws.

Article V

Any audit will be at BASF’s expense. In no event shall BASF initiate more than one audit each Year. Each auditing firm will maintain the confidentiality of Sterling’s accounts and records, and will either verify the correctness thereof or advise both Parties of the composite adjustments required to correct discrepancies for the period audited. Any discrepancies shall be corrected by appropriate payments or credits, as the case may be, at the earliest practicable time, in the amount thereof. If the total amount of such discrepancies exceeds *** for any Year, the Party owing such amount shall also pay the other Party interest on the amount of such discrepancies at the Applicable Interest Rate accruing each Day from the Day such amount was originally due (or paid) until the Day such amount is paid (or refunded) in full.

Article VI

Indemnification; Limitation of Liability; Remedies

          Section 6.01. Indemnification. (a) Except as otherwise provided herein, from and after the Effective Date, Sterling shall defend, indemnify and hold harmless BASF, its Affiliates, their respective present, former and future directors, officers, stockholders, employees and agents and their respective heirs, executors, personal representatives, administrators, successors and assigns (the “BASF Indemnified Persons”), from and against any and all Damages suffered or incurred by any BASF Indemnified Person on account of or arising from or related to:

     (i) the negligence or intentional misconduct of Sterling or any of its employees, contractors, agents or representatives (excluding (A) any act or omission of any third party contractor performing any services contemplated by the Car Service Contract and (B) the choice by Sterling of any third party contractor performing any services contemplated by the Car Service Contract);

     (ii) any Raw Materials, Ancillary Raw Materials or Products during any period when Sterling had risk of loss to such Raw Materials, Ancillary Raw Materials or Products;

     (iii) any Liability or alleged Liability to any third Person, whether incurred under Law or in tort, to the extent such Liability or alleged Liability is based on (A) the Product delivered being a completely different Product than the Product specified in BASF’s Shipment and Storage Instructions; provided, however, that for purposes of this clause (A) a Product shall not be deemed or considered to be a different Product solely because the material delivered fails to meet the applicable Product Specifications, or (B) the Product delivered failing to meet the Product Specifications if (but only if) either (x) Sterling failed to test the quality of the Product prior to shipment or (y) the test of the quality of the Product performed by Sterling showed that the Product failed to meet the Product Specifications in any material respect and Sterling did not inform BASF of such failure and obtain BASF’s express written approval to ship such Product notwithstanding such deficiency prior to the arrival of such Product at its intended destination; and

     (iv) any Liability or alleged Liability to any third Person, whether incurred under Law or in tort, or any environmentally related Claim, arising directly or indirectly from the operations conducted by or on behalf of Sterling at or in

connection with the Plasticizers Complex, or arising out of Spills or Releases Requiring Response Action at the Site occurring before, during or after the term of this Agreement (except to the extent such Liability, alleged Liability or Claim is based on the negligence or intentional misconduct of BASF or any of its employees, contractors, agents or representatives).

          (b) Except as otherwise provided herein, from and after the Effective Date, BASF shall defend, indemnify and hold harmless Sterling, its Affiliates, their respective present, former and future directors, officers, stockholders, employees and agents and their respective heirs, executors, personal representatives, administrators, successors and assigns (the “Sterling Indemnified Persons”), from and against any and all Damages suffered or incurred by any Sterling Indemnified Person on account of or arising from or related to:

     (i) the negligence or intentional misconduct of BASF or any of its employees, contractors, agents or representatives;

     (ii) any Raw Materials or Products during any period when Sterling does not have risk of loss to such Raw Materials or Products (excepting ***);

     (iii) any Liability or alleged Liability to any third Person, *** in each case, to the extent such Liability, alleged Liability or Claim is based on the negligence or intentional misconduct of BASF or any of its employees, contractors, agents or representatives; and

     (iv) any Liability to any Person arising from the *** (except to the extent such Liability arises out of any negligent act or omission of Sterling or intentional misconduct of Sterling in ***, in any case, occurring on or after January 1, 2006, it being understood and agreed that, for purposes of this clause (iv) ***).

          (c) Within a reasonable period of time after a Sterling Indemnified Person or a BASF Indemnified Person (whether one or more, an “Indemnified Person”) receives actual notice of any Damages covered by paragraph (a) or (b) above, as applicable, the Indemnified Person shall, if a claim in respect thereof is to be made pursuant to paragraph (a) or (b) above, as applicable, notify the Party from whom indemnification is sought (the “Indemnifying Party”) in writing of such Damages; provided, however, that the failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any obligation it may have to indemnify the Indemnified Person pursuant to paragraph (a) or (b) above, except to the extent of material detriment suffered by the Indemnifying Party as a result of such failure. In the event that any Damages arise out of or result from matters with respect to third parties (a “Third Party Claim”), the Indemnifying Party will undertake the defense thereof by attorneys chosen by it; provided, however, that if the Indemnifying Party, within a reasonable time after notice of any such Third Party Claim, fails to defend such Third Party Claim actively and in good faith, the Indemnified Person will (upon further notice) have the right to undertake the defense, compromise or settlement of such Third Party Claim, or consent to the entry of a judgment with respect to such Third Party Claim, on behalf of and for the account and risk of the Indemnifying Party, and the Indemnifying Party will thereafter have no right to challenge the Indemnified Person’s defense, compromise,

settlement or consent to judgment. No consent order shall be entered into or Third Party Claim settled unless the Indemnified Person has given its prior written consent thereto, which consent shall not be unreasonably withheld, conditioned or delayed; provided, however, that the Indemnified Person shall consent to any settlement, compromise or discharge of such Third Party Claim that the Indemnifying Party may recommend that by its terms fully releases the Indemnified Person from any further Claims, Liabilities and Losses with respect to the matters giving rise to such Third Party Claim. So long as the Indemnifying Party is defending any Third Party Claim actively and in good faith, the Indemnified Person will not settle such Third Party Claim without the consent of the Indemnifying Party. Each of the Indemnifying Party and the Indemnified Person will be entitled to consult with each other, to the extent it reasonably requests, in respect of the defense of such Third Party Claim and will cooperate in the defense of any such Third Party Claim, including making its officers, directors, employees and books and records available for use in such Third Party Claim, and will take those actions reasonably within its power which are reasonably necessary to preserve any legal defenses to such matters, without the necessity of formal subpoena or court action.

          (d) The Indemnifying Party will promptly pay each Indemnified Person any amount due under this Section 6.01 upon demand therefore, and reimburse each Indemnified Person for all reasonable expenses (including reasonable attorneys’ fees and costs of court) for which the Indemnified Person is entitled to be indemnified hereunder as they are incurred by such Indemnified Person. Upon judgment, determination, settlement or compromise of any Third Party Claim, the Indemnifying Party will, upon demand therefor, promptly pay on behalf of the Indemnified Person, and/or will promptly reimburse the Indemnified Person for its payment of, the amount so determined by such judgment, determination, settlement or compromise and all other claims of the Indemnified Person with respect thereto, unless, in the case of a judgment or determination, an appeal is made therefrom; provided, however, that if the Indemnifying Party desires to appeal from an adverse judgment or determination, then the Indemnifying Party will post and pay the cost of the security or bond to stay execution of the judgment or determination pending appeal. Upon the payment in full by the Indemnifying Party of all of such amounts, the Indemnifying Party will succeed to the rights of the Indemnified Person, to the extent such rights are not waived in settlement, against the third party who made such Third Party Claim. Any amounts which are not paid when due hereunder will bear interest at a rate equal to the Applicable Interest Rate, accruing each Day from the Day such amount was originally due until the Day such amount is paid in full.

          Section 6.02. Force Majeure. (a) If, as the result of the occurrence of a Force Majeure Event, a Party is rendered unable, in whole or in part, to carry out its obligations under this Agreement (other than any obligation to make payment of any amount when due and payable hereunder), the obligations of such Party, insofar as they are affected by such Force Majeure Event, shall be suspended during the continuance of such Force Majeure Event provided that the Party prevented from performing by such Force Majeure Event (i) provides the other Party with written notice of the occurrence or likely occurrence of such Force Majeure Event within a reasonable time, which notice shall describe such Force Majeure Event in reasonable detail and, to the extent practicable, include an estimate of the anticipated duration thereof, (ii) takes all actions

reasonable necessary to remedy such Force Majeure Event or its resulting effects, or otherwise remove the basis for non-performance, with all reasonable dispatch, and (iii) upon such remedy or removal resumes performance of its obligations under this Agreement. Upon receipt of any notice of the occurrence or likely occurrence of a Force Majeure Event, the Parties will consult with each other regarding how such circumstances affect this Agreement and the measures to be taken, and each of the Parties will use commercially reasonable efforts to avoid or reduce the detrimental effects of such Force Majeure Event as much as possible. If by reason of any Force Majeure Event, supplies of any Product deliverable hereunder or Raw Materials or Ancillary Raw Materials are curtailed or cut off, Sterling shall not be required to increase the amount of any Raw Materials or Ancillary Raw Materials acquired from any source of supply or to purchase Products, Raw Materials or Ancillary Raw Materials to replace the Products, Raw Materials or Ancillary Raw Materials so curtailed or cut-off unless BASF agrees to pay incremental costs or expenses associated therewith, in which event such costs and expenses shall be excluded from any calculation of Cost Savings or the Threshold Fixed Costs Amount and, to the extent such costs and expenses are Allocated Fixed Costs, shall be paid separately from, and in addition to, the Allocated Fixed Costs Amount.

          (b) The settlement of strikes or lockouts shall be entirely within the discretion of the Party having the difficulty, and the above requirement that the Party prevented from performing remedy the applicable Force Majeure Event or its resulting effects or otherwise remove the basis for non-performance as soon as practicable shall not require the settlement of strikes or lockouts by acceding to the demands of the opposing party when such course is deemed inadvisable, in the sole discretion of the Party having the difficulty.

          (c) For purposes of this Agreement, the term “Force Majeure Event” means acts of God, wars, blockades, insurrections, riots, epidemics, landslides, lightning, earthquakes, fires, storms, hurricanes, floods, high water, washouts, arrests, restraints of government and people, civil disturbances, explosions, lack of adequate supplies of fuel, power, raw materials, labor, containers or transportation facilities, breakage or accident to ▇▇▇▇▇, machines, equipment, apparatus or lines of pipe or property, freezing of ▇▇▇▇▇, machines, equipment, apparatus or lines of pipe or property, partial or entire failure of any ▇▇▇▇▇, machinery, equipment, apparatus or lines of pipe or other property, strikes, work stoppages, labor difficulties, other industrial disturbances, acts of public enemy, sabotage, governmental controls (including price and allocation controls), Laws (including those dealing with pollution, health, ecology, tariffs, duties or other governmental assessments or restrictions or environmental matters), embargoes, unavailability or shortages of ships, barges, other inland water or marine vessels or other conveyance or, without limitation, any other causes or contingencies (whether or not of the same nature as those hereinbefore specified) beyond the reasonable control of the Party claiming force majeure.

          (d) The failure by a Party to perform any of its obligations under this Agreement shall be deemed to have not been caused by a Force Majeure Event or circumstances reasonably outside its control if such failure results from the shortage of cash or anything reasonably attributable to a Party’s own actions or preventable by a

Party, including through the expenditure of sums which are reasonable in light of the likelihood of the event occurring or the probable effect if is such event were to occur.

          (e) In the event that, at any time during the term of this Agreement, any Governmental Authority adopts any Law and takes any other action or enters any order which directly or indirectly materially and adversely affects the rights or obligations of either Party in this Agreement, then the Party affected by such action shall notify the other Party thereof and the Parties shall enter into good faith negotiations to modify this Agreement to ameliorate the effects of such governmental action. In the event that the Parties fail to agree upon such modifications within 30 Days after receipt of the notice of such action, the Party giving such notice may, upon further written notice, terminate this Agreement. In the event of any such termination of this Agreement, the amount of undepreciated capital paid by BASF for all Capital Projects shall be deemed to be zero and no amount shall be payable by Sterling to BASF pursuant to Section 3.04(e).

          (f) If a Force Majeure Event results in all or substantially all of the operations of the Plasticizers Complex being suspended for a period of at least six consecutive Months, (i) Sterling shall use reasonable efforts to reduce direct Fixed Costs and Variable Costs at the Plasticizers Complex during the pendency of such Force Majeure Event, (ii) BASF shall not be obligated to pay Sterling any Fixed Costs or Facility Fees for the period commencing with the first Day of the seventh Month of such Force Majeure Event and continuing thereafter until the recommencement of operations at the Plasticizers Complex, and (iii) each date specifically referenced in the definition of Early Termination Fee and Section 7.01(b), and the last Day of the Initial Term (if there is no Additional Term) or the final Additional Term, as applicable, shall automatically, without further action of either Party, be deemed to be a later date that is determined by adding to the original date a number of Days equal to the number of Days for which no Facility Fee was payable by BASF pursuant to this paragraph (f). If a Force Majeure Event results in all or substantially all of the operations of the Plasticizers Complex being suspended for a period of at least nine consecutive Months, either Party may, at any time thereafter during the continuance of such Force Majeure Event, terminate this Agreement by providing written notice of such termination to the other Party, such termination to be effective 15 Days after the receipt of such notice by the non-terminating Party.

          Section 6.03. Limitations on Damages. (a) In The Event That Sterling Shall Be Liable To BASF For Any Matter Relating To The Quantity Or Quality Of Any Products Delivered By Sterling To BASF Hereunder, Whether Based Upon An Action Or Claim In Contract, Equity, Negligence Or Otherwise, The Amount Of Damages Recoverable By BASF For All Events, Acts Or Omissions Will Not Exceed, In The Aggregate, An Amount Equal to ***; Provided, However, That Such Limitation Shall Not Apply To Any Liability For Which ***.

          (b) Notwithstanding Anything To The Contrary Contained In This Agreement, Neither Of The Parties Will Be Liable To The Other Party For Any Consequential, Indirect, Special Or Punitive Damages (Including Loss Of Use Of Property Or Lost Profits Or Revenues) From Any Cause Whatsoever, Whether Based In Contract, Tort (Including Negligence), Strict Liability Or

Any Other Legal Theory Unless (i) Such Damages Result From The Gross Negligence Or Intentional Misconduct Of Such Party, (ii) Such Damages Result From Any Breach Of Section 5.06 Or (iii) Such Damages Are Payable By An Indemnified Person Pursuant To A Third Party Claim For Which Indemnification Is Available Hereunder.

          Section 6.04. Remedies. If either Party breaches or otherwise fails to perform its obligations hereunder, the other Party shall be entitled to pursue all legal and equitable remedies for such breach or failure (including specific performance, whether or not such remedy is otherwise normally available).

Article VII

          Section 7.01. Term and Termination. (a) This Agreement shall commence on the date hereof and, unless terminated earlier in accordance with the terms of this Agreement, continue thereafter until December 31, 2013 (the “Initial Term”); provided, however, that upon expiration of the Initial Term, this Agreement shall automatically renew for successive three-year terms thereafter (each, an “Additional Term”) unless this Agreement is terminated earlier in accordance with the terms hereof or either Party gives written notice to the other Party of its intention to not renew this Agreement for an Additional Term at least one year prior to the expiration of the Initial Term or an Additional Term, as the case may be.

          (b) Notwithstanding anything to the contrary contained in paragraph (a) above, BASF shall have the right to terminate this Agreement as of December 31, 2010, December 31, 2011 or December 31, 2012 by (i) providing Sterling with at least one year’s prior written notice of its election to terminate this Agreement and (ii) paying Sterling, on the termination date, the applicable Early Termination Fee.

          (c) This Agreement may also be terminated by mutual prior written consent of the Parties at any time or by either Party if the other Party is in breach of any material covenant, agreement, term, provision or condition of this Agreement, and has failed to cure such breach within 30 Days after receipt from the non-defaulting Party of a written notice of such breach. In the event that Sterling terminates this Agreement based on the breach by BASF of any material covenant, agreement, term, provision or condition of this Agreement, the amount of undepreciated capital paid by BASF for all Capital Projects shall be deemed to be zero and no amount shall be payable by Sterling to BASF pursuant to Section 3.04(e).

     (d) If, within 90 Days after the expiration or termination of this Agreement for any reason, Sterling provides written notice to BASF of its decision to permanently close the PA Unit or the Esters Unit, (i) the amount of undepreciated capital paid by BASF for all Capital Projects associated with the Unit to be permanently closed shall be deemed to be zero and no payment shall be made to BASF by Sterling pursuant to Section 3.04(e) and (ii) if the PA Unit is to be permanently closed, BASF shall have the right, in its sole discretion, to purchase from Sterling *** if, but only if, BASF (A)

provides written notice of its exercise of such right to Sterling within 30 Days after receipt of the notice from Sterling of its election to permanently shut down such Units, (B) pays such amount to Sterling within 30 Days after delivery of such exercise notice to Sterling and (C) reimburses Sterling for all actual costs and expenses incurred in connection with decontaminating, dismantling, packing and transportation of such assets.

(a) In the event of any termination of this Agreement, this Agreement will immediately become void; provided, however, that each provision of this Agreement that is required to ensure the full exercise or performance of the rights and obligations of the Parties hereunder will survive any such termination and (ii) except as otherwise expressly provided in this Agreement, neither Party shall have any liability to the other Party as a result of a termination of this Agreement for any reason; provided, however, that no such termination shall affect any rights or remedies of either Party arising out of any breach of this Agreement prior to such termination or the right of either of the Parties to receive any amount earned or accrued hereunder prior to such termination or otherwise payable with respect to any period prior to such termination.

     (b) Within 30 Days after the expiration or termination of this Agreement, all Raw Materials and Products remaining in Sterling’s possession or custody shall, at the sole cost and expense of BASF, be loaded on ships, barges, other inland water or marine vessels, rail cars, tank trucks or other conveyances, all of which shall be supplied by BASF, for delivery to BASF, with BASF bearing all packing, loading and transportation costs.

          Section 8.02. Counterparts. This Agreement may be executed by the Parties in any number of counterparts, each of which shall be deemed an original instrument, but all of which together shall constitute but one and the same agreement.

     Section 8.03. Benefit and Burden. This Agreement shall inure to the benefit of, and shall be binding upon, the Parties and their respective successors and permitted assigns.

     Section 8.04. No Third Party Rights. Nothing in this Agreement shall be deemed to create any right in any creditor or other person or entity not a Party hereto

(other than the Indemnified Persons) and this Agreement shall not be construed in any respect to be a contract in whole or in part for the benefit of any other third party.

     Section 8.05. No Partnership or Agency. This Agreement shall not be construed to create a partnership, joint venture, association or other entity or business organization or to create a principal-agent relationship between the Parties.

     Section 8.06. Amendments and Waiver. No amendment, modification, restatement or supplement of this Agreement shall be valid unless the same is in writing and signed by the Parties. No amendment or modification of this Agreement shall be effected by the sending, acknowledgment or acceptance of any purchase order, acknowledgment or other form containing terms or conditions at variance with or in addition to those set forth in this Agreement. No waiver of any provision of this Agreement shall be valid unless in writing and signed by the Party against whom that waiver is sought to be enforced. No failure or delay on the part of either Party in exercising any right, power or privilege hereunder, and no course of dealing between the Parties, shall operate as a waiver of any right, power or privilege hereunder. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder. No notice to or demand on either Party in any case shall entitle such Party to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of either Party to any other or further action in any circumstances without notice or demand.

     Section 8.07. Assignments. Neither this Agreement nor any right, interest or obligation hereunder may be assigned by either Party without the prior written consent of the other Party and any attempt to do so shall be null and void; provided, however, (a) that no such consent shall be required for assignment for collateral purposes or to a successor in interest of all or substantially all of the assets or business of either Party to which this Agreement relates and (b) no assignment by either Party of any of its rights, interests or obligations hereunder shall relieve such Party of its obligations under this Agreement unless the other Party expressly agrees otherwise in writing.

     Section 8.08. Severability. Should any clause, sentence, paragraph, subsection or Section of this Agreement be judicially declared to be invalid, unenforceable or void, such decision will not have the effect of invalidating or voiding the remainder of this Agreement, and the Parties agree that (a) the part or parts of this Agreement so held to be invalid, unenforceable or void will be deemed to have been stricken herefrom as if such stricken part or parts had never been included herein and (b) the Parties shall substitute a valid, lawful and enforceable provision, with economic effects that are as equivalent as reasonably possible, for such invalid, unenforceable or void part or parts of this Agreement.

          Section 8.09. Dispute Resolution Procedures. (a) As used in this Section 8.09, “Dispute” means any and all questions, claims controversies or disputes arising out of or relating to this Agreement, including the validity, construction, meaning, performance, effect or breach of this Agreement, other than any questions, claims, controversies or disputes relating to the breach or alleged breach of Section 5.06. Each Party agrees that the procedures set forth in this Section 8.09 shall be the sole and

exclusive remedy in connection with any Dispute and irrevocably waives any right to commence any action, suit or proceeding in or before any governmental authority, except as expressly provided in this Section 8.09.

          (b) In the event of any Dispute between the Parties, the Parties shall promptly and in good faith attempt to resolve such Dispute through negotiations. A disputing Party shall give written notice of the Dispute to the other Party that shall contain a brief statement of the nature of the Dispute. If the Parties are unable to resolve the Dispute within 30 Days after receipt of such notice by the other Party, the Parties shall submit the Dispute to mediation as set forth in paragraph (c) below.

          (c) The mediation of any Dispute hereunder shall be conducted in accordance with the Commercial Mediation Rules and Procedures of the American Arbitration Association (“AAA”). Each Party shall have the right to be represented by counsel in any mediation. The Parties shall attempt to agree upon an impartial mediator to mediate the Dispute, but if they are unable or fail to appoint a mediator within ten Days of the filing of a written request for mediation with the AAA, the AAA will appoint a qualified mediator to serve unless the Parties mutually agree to extend such time period. The mediation shall be held in New York, New York within 30 Days of appointment of the mediator unless the Parties mutually agree to hold the mediation at some other time or place. Any opinion expressed by the mediator shall be strictly advisory and shall not be binding on the Parties, nor shall any opinion expressed by the mediator be admissible or be made known to the arbitrator in any arbitration proceedings. Costs of the mediation shall be borne equally by the Parties, except that each Party shall be responsible for its own expenses.

          (d) If the Parties are unable or fail to settle their Dispute through mediation as provided in paragraph (c) within 10 Days after the commencement of the mediation, the Dispute shall be settled by binding arbitration administered by the AAA in accordance with its Commercial Arbitration Rules and Procedures unless the Parties mutually agree in writing that such Dispute shall no longer be subject to this Section 8.09. Either Party who fails or refuses to submit to such binding arbitration shall bear all costs and expenses incurred by such other Party in compelling arbitration of such Dispute. With respect to a Dispute in which the claims or amounts in controversy do not exceed $200,000, a single arbitrator shall be chosen and shall resolve the Dispute. In such case, the arbitrator shall have authority to render an award up to but not exceeding $200,000. With respect to a Dispute in which the claims or amounts in controversy exceed $200,000, such Dispute shall be decided by a majority vote of a panel of three arbitrators, with each Party appointing one arbitrator, and with the Party-appointed arbitrators appointing the third, neutral arbitrator, who will act as chairperson of the tribunal. For any Dispute being decided by a panel of three arbitrators, the determination of any two of the three arbitrators will constitute the determination of the arbitration panel; provided, however, that all three arbitrators on the arbitration panel must actively participate in all hearings and deliberations. Each arbitrator selected pursuant to this paragraph (d) (i) shall be qualified by training, education and experience to rule on the issues presented, (ii) shall an AAA approved arbitrator and (iii) shall not be an employee, agent or representative of either Party or of an Affiliate of either Party. The arbitration shall be held in New York, New York unless the Parties mutually agree in writing to hold the arbitration at some other place. The Parties

expressly agree to consolidation of arbitral proceedings that concern common issues of fact or law. The award shall be in writing and shall state the reasoning on which the award rests. A judgment on the award may be entered in any court of competent jurisdiction.

          (e) In the event that a Dispute is submitted to arbitration pursuant to paragraph (d) above, either Party may request limited document production from the other Party of specific and expressly relevant documents, with the reasonable expenses of the producing Party incurred in such production paid by the requesting Party. Any such discovery (which rights to documents shall be substantially less than document discovery rights prevailing under the Federal Rules of Civil Procedure) shall be conducted expeditiously. Depositions, interrogatories or other forms of discovery (other than the document production, set forth above) shall not occur except by consent of the Parties. All discovery requests will be subject to the Parties’ rights to claim any applicable privilege. The arbitrator or the arbitration panel, as the case may be (in either case, the “Arbitrator”), will adopt procedures to protect the proprietary rights of the Parties and to maintain the confidential treatment of the arbitration proceedings (except as may be required by Law). Subject to the foregoing, the Arbitrator shall have the power to issue subpoenas to compel the production of documents relevant to the Dispute, to impose sanctions, to permit or order depositions and discovery and to take such other actions as the Arbitrator deems necessary to the same extent a judge could pursuant to the Federal Rules of Civil Procedure and applicable Law.

          (f) The Arbitrator shall have full power and authority to determine issues of arbitrability but shall otherwise be limited to interpreting or construing the applicable provisions of this Agreement, and will have no authority or power to limit, expand, alter, amend, modify, revoke or suspend any condition or provision of this Agreement or to award damages in excess of the amount or other than the types allowed by this Agreement. In addition, the Arbitrator may not, in any event, make any ruling, finding or award that does not conform to the terms and conditions of this Agreement. If a Party fails or refuses to appear at and participate in an arbitration hearing after due notice, the Arbitrator may hear and determine the controversy upon evidence produced by the appearing Party.

          (g) At any time after submission of a written notice of Dispute, either Party may request a court of competent jurisdiction to grant interim measures of protection (i) to preserve the status quo pending resolution of the Dispute, (ii) to prevent the destruction of documents and other information or things related to the Dispute, or (iii) to prevent the transfer, dissipation or hiding of assets. A request for such interim measures to a judicial authority shall not be deemed incompatible with the provisions of this Section 8.09 or a waiver of a Party’s right to arbitrate.

          (h) By submitting a written notice of Dispute pursuant to paragraph (b) above, all applicable statutes of limitations and defenses based on the passage of time shall be tolled while negotiation, mediation and arbitration proceedings are diligently conducted pursuant to this Section 8.09. The Parties will take such action, if any, required to effectuate such tolling.

          (i) The costs of the arbitration (including the Arbitrator) shall be borne equally by the Parties, except that each Party shall be solely responsible for its own costs and expenses, including the costs of legal representation and assistance and for experts.

     “Arrival Date” means, with respect to any Vessel, the calendar day (commencing at 0001 of such calendar day) on which such Vessel is scheduled to arrive at the Terminal in accordance with Section 2 below.

     “Cargo” means, with respect to any Vessel, the goods, raw materials or products which are to be loaded onto or unloaded from such Vessel.

     “ETA” means, with respect to any Vessel, the estimated time of arrival of such Vessel.

     “NOR” means, with respect to any Vessel, Notice of Readiness of such Vessel.

     “Party” has the meaning specified in the Agreement.

     “Ship” means a boat, ship, tanker or other inland or marine water vessel.

     “Sterling” means Sterling Chemicals, Inc.

     “Terminal” means a plant or terminal facility delivering or receiving Cargo.

     “Terminal Party” means the Party responsible for delivering the Cargo onto or for receiving the Cargo from a Vessel.

     “Tow” means any combination of Vessels functioning as a single unit.

     “Vessel” means a barge or Ship.

     “Vessel Party” means the Party responsible for providing the Vessel, irrespective of whether such Vessel is delivering or receiving the Cargo.

          Section 2. Vessel Nomination. (a) Ships. Not less than seven days prior to the ETA of a Ship, the Vessel Party shall provide a written nomination for such Ship to the Terminal Party. The Terminal Party shall confirm the nomination in writing based on the dock availability and approval by Sterling’s vetting process. If the Terminal Party does not accept the Ship then

the Terminal Party shall indicate each unacceptable item in writing. Once all of the items are resolved, the Terminal Party shall accept the Ship.

          (b) Barges. Not less than five days prior to the ETA of a barge, the Vessel Party shall provide the nomination for such barge to the Terminal Party with an arrival window of no more than three days. The Terminal Party shall confirm the nomination in writing based on the dock availability and approval by Sterling’s vetting process. If the Terminal Party does not accept the barge then the Terminal Party shall indicate each unacceptable item in writing. Once all of the items are resolved, the Terminal Party shall accept the barge.

          Section 3. Notice of Arrival. The Notice of Arrival shall be given by the Vessel to the Terminal Party by telephone or radio not less than 72 hours (or within reason for a given Cargo) prior to the ETA of such Vessel for purposes of fixing the berthing time. The ETA shall be reconfirmed daily until the Vessel arrives for loading. When the Vessel’s ETA is within 24 hours then the master of the Vessel shall promptly notify the Terminal Party of the new ETA if the ETA has changed by three hours or more (plus or minus). In no event shall notice of arrival time constitute an agreement to alter the laycan or the arrival window.

          Section 4. Vessel Requirements. Each Vessel nominated by a Vessel Party shall meet the general vessel requirements of the Terminal. In no event will nomination or acceptance of confirmation of a Vessel be deemed or constitute a waiver of such requirements.

          Section 5. Notice of Readiness. (a) Ships. After a Ship has received all port clearances and arrived at the anchorage or other place of waiting, and is otherwise in all respects ready to receive or discharge the goods or products, the master of the Ship (or his agent) shall tender NOR of the Ship to the Terminal by letter, telegraph, telex, facsimile or electronic message means or other written communication. The Terminal shall attempt to berth the Ship on an equal basis with all other Vessels arriving at the port to load or discharge cargoes in the same order as the order in which the Terminal receives NORs from the Ship and all other Vessels. The giving or acceptance of NOR shall not be deemed or construed to constitute an acceptance or change in the Ship’s laycan. If a Ship tenders NOR prior to 0001 hours, local time, of the first day of the laycan, such NOR shall not be effective until 0001 hours, local time, of the first day of the laycan, unless the Terminal elects to accept the Ship earlier, in which case used laytime shall commence when the Ship is all fast. Unless the Terminal Party consents otherwise in writing, in no event will laytime commence prior to 0600 on the first day of the laycan.

          (b) Barges. When the barge is four hours from arriving at the Terminal, the barge owner, agent or pilot shall notify the Terminal. The Terminal shall attempt to berth the barge on an equal basis with all other Vessels arriving at the port to load or discharge cargoes in the same order in which the Terminal receives the four hour notifications or NORs from the barge or Ship, respectively.

          Section 6. Vessel Berths. The Terminal shall provide a berth for the Vessel at which the Vessel can always lie safely afloat (within the specified maximum drafts and specified minimum water depths, free of all wharfage and dockage dues. All duties and other charges on the Vessel, including, without limitation, those incurred for tugs and pilots, mooring masters,

other port costs and tax on services for Cargo transfer, shall be borne by the Vessel. Neither the Terminal nor the Terminal Party shall be deemed to warrant the safety of any channel, fairway, anchorage or other waterway used in approaching the designated berth or be liable for any loss, damage, injury or delay to Vessel resulting from the use of such waterways not caused by its fault or neglect. The Terminal Party shall have the right to shift the Vessel from one berth to another, or to anchorage; provided, however, that the Terminal Party shall be responsible for all costs and expenses incurred in such shifting or anchoring of the Vessel, with the time consumed in the shifting counted as used laytime. Expenses incurred for any shifting of the Vessel within a port by one of the Parties hereto for the sole convenience of such Party shall be for that Party’s account.

          Section 7. Laytime. (a) Ships. The allowed laytime shall be either a specified number of hours or at a pumping rate as defined in the Agreement, subject to a 12-hour minimum. If allowed laytime is not specified in the Agreement, then laytime allowed shall be the number of hours or at the pumping rate (in metric tons per hour) set forth below and based on Cargo lot size, or as may otherwise be mutually agreed between the Parties. If the Terminal will not permit loading or discharging of Cargo within the specified time or at the agreed pumping rate, then the additional time necessary therefore shall be deemed to be used laytime.

Cargo Lot Size		Loading/Unloading Rate
³ 6,000 MTs		▇▇▇ ▇▇/▇▇
▇ 2,000 but < 6,000 MTs		▇▇▇ ▇▇/▇▇
▇ 1,000 but < 2,000 MTs		75 MT/hr
< 1,000 MTs		12 hrs

If a Vessel arrives on the first day of the laycan, laytime shall commence on the later of (i) six hours after acceptance of NOR from the Terminal to load or discharge, and (ii) Vessel arrival and completion of mooring at berth (all fast). The Terminal Party shall always be entitled to the six hours tendering allowance, if needed, whether or not allowed laytime has expired and whether or not the Ship is on demurrage. In the event a Ship arrives prior to the commencement of laydays, laytime shall not commence before 0600 hours local time on the date of commencement of laydays unless the Ship is berthed prior to this time with the Terminal Party’s consent. In the event the Terminal Party agrees to load the Ship prior to commencement of laydays, all such time to be credited against any time the Ship is on demurrage. For purposes of this clause, time to count when the Ship commences loading.

          (b) Barges. The allowed laytime shall be either a specified number of hours or at a pumping rate as defined in the Agreement, subject to an 8-hour minimum. If allowed laytime is not specified in the Agreement, then laytime allowed shall be the number of hours or at the pumping rate (in metric tons per hour) set forth below and based on Cargo lot size, or as may otherwise be mutually agreed between the Parties. If the Terminal will not permit loading or discharging of Cargo within the specified time or at the agreed pumping rate, then the additional time necessary therefore shall be deemed to be used laytime.

Cargo Lot Size		Loading/Unloading Rate
³ 30,000 BBLs		24 hours
³ 20.000 but < 30,000 BBLs		16 hours
< 20,000 BBLs		12 hours

If the barge arrives on the first day of the arrival window, laytime shall commence when the barge is spotted at the dock and the mooring at berth (all fast) is completed but no earlier than 0400 hrs.

     (c) Time consumed due to any of the following shall not count as used laytime:

     (i) any delay to the Vessel in reaching or departing the berth (including weather delays) caused by any reason or condition not reasonably within the Terminal Party’s control;

     (ii) any time consumed by the Vessel in moving from port anchorage to all fast in berth including, but not limited to, awaiting daylight, tide, tug boats or pilots or time consumed by the Vessel lining up;

     (iii) any delay due to the Vessel’s condition, breakdown or failure to maintain agreed pumping rates, or inability of the Vessel’s facilities to load or discharge Cargo;

     (iv) any delay due to prohibition of loading or discharging at any time by the owner or operator of the Vessel or by the port authorities, unless such prohibition is caused by the Terminal’s failure to comply with applicable laws or regulations;

     (v) any delay due to Vessel bunkering or provisioning;

     (vi) any delay due to Vessel discharging or shifting of ballast, slops or contaminated cargo;

     (vii) any delay due to pollution or threat thereof caused by any defect in the Vessel, or any act or omission of the master or crew of the Vessel;

     (viii) any delay due to the Vessel’s violation of the operating and/or safety regulations of the Terminal, noncompliance with federal or state law or Coast Guard or other applicable regulations, or failure to obtain or maintain an oil pollution responsibility certificate;

     (ix) any delay caused by strike, lockout, work stoppage or restraint of labor of master, officers or crew of the Vessel, or of tugboats or pilots; and

     (x) any time spent awaiting customs and immigration clearance.

Used laytime shall cease upon disconnection of hoses or cargo arms after all Cargo has been loaded or discharged. The Vessel shall vacate the berth expeditiously, consistent with safe operating practices (unless permission to remain is given).

          Section 8. Demurrage. Demurrage will be paid for all time that used laytime exceeds the allowed laytime at the rate specified in the Agreement. If the demurrage rate is not specified in the Agreement, demurrage shall be paid based upon parcel size and at the applicable charter party rate, provided that the Vessel Party gave the Terminal Party the laytime and demurrage rate information with the vessel nomination. If the Terminal Party has this information and accepts the vessel nomination, the demurrage, if any, will be paid at the charter party rate. If the demurrage rate was not provided, then the Terminal Party may elect to pay based on the schedule below.

Ship Size		Rate
³ 40,000 DWT		$20,000/day prorated
³ 25,000 but < 40,000 DWT		$15,000/day prorated
³ 10,000 but < 25,000 DWT		$10,000/day prorated
< 10,000 DWT		$7,500/day prorated

For Ships with parcel sizes less than 1,000 MT, the Terminal Party shall pay demurrage, if any, at $7,500/day prorated unless mutually agreed otherwise.

Barge Size		Rate
³ 30,000 BBLs		$100/hr prorated
³ 20,000 but < 30,000 BBLs		$90/hr prorated
³ 10,000 but < 20,000 BBLs		$90/hr prorated

For barges with parcel sizes less than 1,000 MTs, the Terminal Party shall pay 50% of any applicable demurrage. Demurrage incurred in port by reason of fire, explosion, storm, weather, strike, lockout, work stoppage or restraint of labor or by breakdown of machinery or equipment in or about the Terminal shall be paid for at one-half the rate otherwise provided for demurrage. The Terminal Party will be responsible for demurrage if such failure results from the Terminal Party’s shortage of cash or anything reasonably attributable to the Terminal Party’s own actions (including delays at the Terminal causing loading or unloading to exceed the allowed laytime) or preventable by the Terminal Party, including through the expenditure of sums which are reasonable in light of the likelihood of the event occurring or the probable effect is such event were to occur and, if such demurrage has been paid by the Vessel Party, the Terminal Party will reimburse the Vessel Party for such demurrage. Demurrage claims must be submitted within 90 days from the date of completion of discharge of the Cargo and must be accompanied by the Notice of Readiness, the Master’s Port Log with Pumping Record, the Agent’s Port Log, the Laytime Statement, the Charter Party Agreement and telexes or other documentation supporting original Ship nomination. Any claim for demurrage which is not accompanied by such documentation shall be deemed waived and forever barred.

          Section 9. Delivery, Title and Risk. Delivery of Cargo shall be to or from the Terminal designated by the Terminal Party onto or from the Vessel nominated by the Vessel Party in accordance with the terms of the Agreement. Unless otherwise specified in the

Agreement, title to, and risk of loss of, all or any of the Cargo shall pass at the flange connection between the Vessel’s cargo manifold and the hose connection at the Terminal.

          Section 10. Quantity and Quality. Unless otherwise provided in the Agreement, Cargo quantity and quality shall be determined by an independent and mutually acceptable inspector, the cost of which shall be shared equally between the Parties, and whose determinations as to quantity and quality shall be conclusive and binding upon the Parties.

          Section 11. Cargo Vulnerable To Heating (Styrene Monomer Only). The Vessel Party shall not stow the Cargo in tanks adjacent to tanks which contain heatable cargoes or are otherwise subject to heating.

          Section 12. Hoses. The Terminal Party agrees to connect the hose at the shore and to use the shore facility crane to lift the hose to the Vessel’s manifold where the Vessel Party agrees to connect and disconnect hoses to the Vessel’s manifold.

          Section 13. Cleaning. The Vessel shall arrive at the Terminal with all cargo tanks, pumps and pipes suitably clean to the satisfaction of the Terminal Party’s Inspector. The Vessel Party shall ensure that all traces of sediment, tank washings or chemicals, if used, are removed from tanks, pumps and pipes intended for carriage of designated Cargo. Any delays as a result of the Vessel arriving at the Terminal and not being suitable condition to load the designated Cargo, shall be for the Vessel Party’s account and the laytime shall not count.

          Section 14. Gangway. The Terminal Party shall not be responsible for providing or assisting in the set up of the gangway. Any time lost shall be for the Vessel Party’s account.

          Section 15. Texas City Terminal Restrictions. No Vessel shall be allowed to lighter, engage in slop disposal, clean tanks while on berth or bunker.

          Section 16. Excess Berth Occupancy. If, after disconnection of cargo hoses, the Vessel remains at the berth exclusively for the Ship’s purposes, other than by reasons of Force Majeure, the Vessel Party shall be responsible for direct costs incurred by the Terminal Party.

          Section 17. Conflict. In the event of any conflict between these Marine Provisions and the provisions of the Agreement, the provisions of the Agreement shall prevail and be given effect.

          Section 18. Pollution Prevention. Regardless of the nature of the Cargo carried, all Vessels and all towboats and barges transporting any of the Cargo shall have pollution liability insurance coverage that is sufficient to at least meet all applicable statutory pollution liability limits.

          Section 19. Damage and Injury. The Vessel and the Vessel Party assume full responsibility for any injury to and/or death of persons, as well as damage sustained by wharves, berths or docks owned, operated or maintained by the Terminal and the Terminal Party arising out of the negligent or improper operation of the Vessel, tows, barges, or any other waterborne

craft, either owned or operated by the Vessel or the Vessel Party, or being operated by subcontractors by the Vessel or the Vessel Party. The Vessel and the Vessel Party shall fully indemnify the Terminal and the Terminal Party for any such injury, death or damage.

          Section 20. Terminal Regulations. All Vessels will comply with any regulations specific to the Terminal. Any Vessel not in compliance with such regulations may not be permitted to dock or may be directed to disconnect and leave the dock or berth, with all and any resulting costs and expenses borne solely by, and for the account of, the Vessel Party.
