additional delivery, shipment and storage instructions and Sterling shall use reasonable

-16-

 

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

     (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,

-17-

 

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

     (e) In the event that, at any time after the Commissioning Period, BASF desires to substitute
an Esters Product for *** then being produced, (i) the Threshold Fixed Costs Amount shall be
increased by an amount equal to the actual increase in direct and allocated Fixed Costs resulting
from such change, (ii) such additional direct and allocated Fixed Costs shall thereafter be
included in the calculation of the Threshold Fixed Costs Amount 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. In the event that BASF desires to produce more than *** in the
Esters Unit in any given Month, the Parties will negotiate in good faith appropriate increases in
the Threshold Fixed Costs Amount, the Allocated Fixed Costs Amount and the impact on any
calculation of Costs Savings, and, in the absence of agreement on such matters, Sterling shall not
be required to produce such additional Esters. If BASF desires to add other products or substitute
a product for any Product, Sterling will produce such other products so long as (i) either no
modification of the Plasticizers Complex is required or BASF pays for all such modifications, (ii)
neither such production nor any required modifications to the Plasticizers Complex will
unreasonably affect the operations of the Plant and (iii) any required amendment to Sterling’s air
permit has been obtained. Sterling shall use commercially reasonable efforts to expeditiously
obtain any required amendment to the air permit.

     (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

-18-

 

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.

Sterling, or cause to be furnished to Sterling, all Raw Materials used in the production of
Products in such quantities and at such times as are required for Sterling to perform its
production and delivery obligations to BASF; provided, however, that (i) Sterling shall notify BASF
in writing of its requirements for Raw Materials at such times as will allow BASF to supply such
Raw Materials in the ordinary course and permit Sterling to fulfill its production and delivery
obligations hereunder, and (ii) the failure by Sterling to provide such notice to BASF shall not
relieve Sterling of any of its obligations under this Agreement. BASF shall provide Sterling with
written notice of the expected dates of arrival of each shipment of Raw Materials in accordance
with Section 2.01(b).

required for all deliveries of Raw Materials and shipments of Products under this Agreement;
provided, however, that (i) Sterling shall make Rail Cars available to BASF pursuant to the Car
Service Contract between the Parties until July 31, 2006, and (ii) notwithstanding anything to the
contrary contained in the Car Service Contract between the Parties, BASF shall pay *** of the costs
and expenses pertaining to the Rail Cars, including maintenance costs and expenses. Upon the
written request of BASF, Sterling shall, with the prior written consent of the relevant Rail Car
owner, assign to BASF any leases for Rail Cars leased by Sterling in connection with the delivery
of Products pursuant to this Agreement for a

-19-

 

term mutually acceptable to BASF and the relevant Rail Car owner. BASF shall be solely responsible
for arranging and providing any emergency response measures required in connection with any ship,
barge, other inland water or marine vessel, rail car, tank truck or other conveyance (except that
Sterling shall provide emergency response measures, at the cost and expense of BASF, if the
applicable ship, barge, other inland water or marine vessel, rail car, tank truck or other
conveyance is physically located at the Site). Notwithstanding anything to the contrary contained
in the Car Service Contract, the Car Service Contract will terminate and cease to be of any further
force or effect on July 31, 2006; provided, however, that BASF may, by providing written notice to
Sterling, elect to terminate the Car Service Contract prior to that time, in which event BASF shall
be responsible for any and all costs and expenses resulting from the early termination of any rail
car leases covering any of the Rail Cars 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

(iii) perform such additional testing, statistical process control and statistical quality control
for Products as may be reasonably requested by BASF. BASF shall also have the right to further
test Products prior to shipment hereunder. Sterling shall cooperate in any such test, and shall
have the right to be represented and to participate in any such test, and to inspect any equipment
used in determining the nature or quality of any Product. The cost of all inspecting, sampling,
testing and coding hereunder shall be included in Fixed Costs. All records or certifications shall
be kept for a period of not less than one year (or for the duration of any contest with respect
thereto, if longer), and all samples shall be kept for a period of not less than 90 Days (or for
the duration of any contest with respect thereto, if longer), with the procedures for taking
samples at the unloading flange for Raw Materials and the procedures for taking samples of Products
as of the date of shipment to be mutually agreed upon by the Parties. All records, certifications
and samples shall be made available to BASF on request. The retained sample for any Raw Materials
or Ancillary Raw Materials shall be the exclusive source for determining whether any Raw Materials
or Ancillary Raw Materials meet the applicable Raw Materials Specifications, and the retained
sample for any Product shall be the exclusive source for determining whether any Product meets the
applicable Product Specifications.

          (b) Subject to the terms of this Agreement, Sterling shall accept any and all deliveries of
Raw Materials; provided, however, that Sterling may reject any delivery of Raw Materials if
Sterling notifies BASF in writing, within 10 Business Days after the delivery of such Raw Materials
to Sterling, of the failure of such Raw Materials to meet the applicable Raw Materials
Specifications. In the event that Sterling rejects any delivery of Raw Materials, BASF may object
to such rejection in writing within five Business Days after receipt of the relevant notice from
Sterling, in which event the Parties will meet within three Business Days after delivery of such
objection to resolve the question of whether such Raw Materials meet the applicable Raw Materials
Specifications. If the Parties are unable to resolve the matter during such meeting,

-21-

 

either Party may refer the matter to an independent surveyor or chemical laboratory mutually
agreeable to the Parties, such agreement will not be unreasonably withheld, for testing the
retained sample of such Raw Materials under the agreed upon procedure. The findings of the
independent surveyor or chemical laboratory will be conclusive and binding upon the Parties. If
any Raw Materials fail to meet the applicable Raw Materials Specifications and BASF does not timely
make available other Raw Materials meeting the applicable Raw Materials Specifications, Sterling’s
manufacturing and delivering obligations hereunder shall be reduced accordingly.

          (c) Subject to the terms of this Agreement, BASF shall accept any and all deliveries of
Products; provided, however, that BASF may reject any delivery of Products if BASF notifies
Sterling in writing, within 45 Business Days after the later of delivery of such Products to BASF
or delivery of such Products to a BASF customer (if shipped directly from the Site to such
customer), of the failure of such Product to meet the applicable Product Specifications as of the
date of shipment. In the event that BASF rejects any delivery of Products, Sterling may object to
such rejection in writing within five Business Days after receipt of the relevant notice from BASF,
in which event the Parties will meet within three Business Days after delivery of such objection to
resolve the question of whether such Products meets the applicable Product Specifications. If the
Parties are unable to resolve the matter during such meeting, either Party may refer the matter to
an independent surveyor or chemical laboratory mutually agreeable to the Parties, such agreement
will not be unreasonably withheld, for testing the retained sample of such Product under the agreed
upon procedure. The findings of the independent surveyor or chemical laboratory will be conclusive
and binding upon the Parties. If any Products fail to meet the applicable Products Specifications,
Sterling shall reprocess such Products to meet the applicable Products Specifications or deliver
replacement Products that meet the applicable Products Specifications.

          Section 2.06. Quantity Measurement and Testing. (a) The unit of measurement of
Products and Raw Materials shall be one pound (avoirdupois). All quantities referred to herein,
unless otherwise expressly stated, are in terms of such unit of measurement.

          (b) Quantities of Raw Materials and Products delivered by ship, barge or other inland water or
marine vessel shall be determined by taking the opening and closing inventory of Sterling’s
properly calibrated shore tanks before and after loading or unloading such shipment, unless
otherwise provided hereunder. Quantities of Raw Materials and Products delivered by rail car or
tank truck shall be determined by weighing the applicable rail cars or tank trucks on Sterling’s
certified scales before and after loading.

          (c) Sterling shall maintain and operate the Measuring Equipment in accordance with customary
practice in the industry, and all Measuring Equipment, including all scales, meters and
thermometers, shall be certified for accuracy at least once every Year by an independent service.
BASF may, at its option and expense, install measuring equipment for checking the Measuring
Equipment, so long as such installation does not unreasonably interfere with the operation of the
Plasticizers Complex or the Plant. Each Party shall have the right to be present at the time of
any calibrating, installing, reading, cleaning, changing, repairing, inspecting, testing or

-22-

 

adjusting of the Measuring Equipment or any measuring equipment used to check the Measuring
Equipment. Each Party will maintain all records, charts and weigh tickets pertaining to deliveries
of Raw Materials and Products hereunder for a period of at least one year (or for the duration of
any contest with respect thereto, if longer). The records from the Measuring Equipment shall
remain the property of Sterling and the records of any additional measuring equipment installed by
BASF shall remain the property of BASF; provided, however, that, upon request, each Party will
submit to the other Party copies of its records, charts and weigh tickets, together with
calculations therefrom. If any of the Measuring Equipment is found to be inaccurate to any degree,
Sterling shall repair, calibrate and certify such Measuring Equipment to measure accurately.

          Section 2.07. Storage of Raw Materials and Products. Sterling shall use the Bulk
Storage Tanks for the storage of Raw Materials and Products, as designated by BASF in the Estimated
Delivery, Shipment and Storage Instructions and the Delivery, Shipment and Storage Instructions, or
as otherwise determined by Sterling. Should any Bulk Storage Tank be taken out of service by
Sterling for repair or service, Sterling will repair such Bulk Storage Tank and place it back in
service as soon as practicable and, pending the completion of such repair, Sterling shall make
available for the storage of Raw Materials and Products any other suitable bulk storage tanks it
then has available at the Plant. Sterling shall, at all times, physically segregate all Raw
Materials furnished by BASF and all Products produced by Sterling for BASF at the Site or other
storage facilities from all chemicals, packaging materials and products owned by Sterling or third
parties.

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.

-23-

 

          (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.

-24-

 

          (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

-26-

 

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

-27-

 

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 Sterling
deems 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

-28-

 

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

-29-

 

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

-30-

 

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

-31-

 

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.

-32-

 

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

-33-

 

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.

-34-

 

          (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

-35-

 

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

-36-

 

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.

-37-

 

          (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

-38-

 

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

Additional Agreements

          Section 5.01. Title. (a) Sterling expressly does not by the terms of this Agreement,
sell, transfer or assign to BASF any right, title or interest in the Plasticizers Complex or the
Plant or any assets or properties of Sterling, and nothing in this

-39-

 

Agreement shall be deemed to convey to BASF any legal or beneficial ownership in or to all or any
portion of the Plasticizers Complex, the Plant or any other assets or properties of Sterling.
Title to all Raw Materials and Product shall at all times remain in BASF. Title to Product shall
vest in BASF as of the time of its production. Sterling shall not impose or permit to be imposed
upon any of the Raw Materials or Products within the custody and control of Sterling any Liens
other than those created by, through or in favor of BASF. Notwithstanding anything to the contrary
contained in any prior agreement or any understanding between the Parties (including the Existing
Agreement), upon the execution of this Agreement, title to any Raw Materials or Product on hand (at
the Site, at terminals, in route and elsewhere) shall vest in BASF as if such Raw Materials or
Product were supplied pursuant to the terms of this Agreement.

          (b) Sterling hereby authorizes BASF to file any and all UCC financing statements that are
necessary to evidence or perfect BASF’s ownership of all rights, title and interests in the Raw
Materials and Products referred to in Section 5.01(a). Upon the request of BASF, Sterling shall
execute and deliver to BASF any other notices as may be reasonably requested by BASF to reflect and
file of record BASF’s ownership of all rights, title and interests in and to all Raw Materials and
Products referred to in Section 5.01(a).

          (c) On the earlier of (i) February 28, 2006 and (ii) the Day after BASF notifies Sterling in
writing that it has made all filings it desires to make pursuant to paragraph (b) above, the
Security Agreement dated                     , 1986 (left blank in original) between the Parties shall
terminate and all liens and security interests granted therein shall automatically be released and
discharged. BASF hereby authorizes Sterling to file, at any time on or after such date, any and
all UCC financing statements that are necessary to release such liens and security interests of
record. Upon the request of Sterling, BASF shall execute and deliver to Sterling any other notices
as may be reasonably requested by Sterling to release such liens and security interests of record.

          Section 5.02. Sale or Transfer of Interest in the Plasticizers Complex. During the
term of this Agreement, Sterling may not sell or transfer an interest in all or any part of the
Plasticizers Complex to a Competitor without the prior written consent of BASF, which consent will
not be unreasonably withheld, conditioned or delayed. Notwithstanding the foregoing, (a) Sterling
may sell or otherwise dispose of the Plasticizers Complex to a Competitor as part of the sale,
transfer or other disposition of all or substantially all of the Plant’s assets, directly or
indirectly, or as a part of the merger, consolidation, reorganization or sale of all or
substantially all of the assets or equity of Sterling (each, a “Plant Disposition”), and
(b) except as set forth in Section 5.01, Sterling may grant Permitted Encumbrances and other Liens
in or on the Plasticizers Complex to secure any indebtedness of Sterling, now existing or hereafter
arising, and any holder of such indebtedness may foreclose upon all or any portion of the
Plasticizers Complex, sell such assets in lieu of foreclosure and otherwise exercise all rights or
remedies they may have with respect thereto, without restriction hereunder, and any purchaser on
foreclosure or sale in lieu of foreclosure may take such assets free from such restrictions.

          Section 5.03. Books and Records; Audits. Sterling shall maintain accurate records and
books of account with regard to the operation of the Plasticizers Complex and the transactions
contemplated by this Agreement, and furnish a report thereon to BASF, in a form reasonably
acceptable to BASF, within 21 Days following the end of each Month. All accounting and reporting
for the operation of the Plasticizers Complex and the transactions contemplated by this Agreement
will be in accordance with GAAP. Upon reasonable request, each Party shall provide the other Party
with copies of all purchase orders, invoices and other backup data pertaining to any costs or
expenses related to this Agreement, and the Party receiving such information shall maintain the
confidentiality of all such documents and information in accordance with the provisions of Section
5.06.

          (b) Upon reasonable request, Sterling shall provide BASF with access to all records pertaining
to the operation of the Plasticizers Complex and the transactions contemplated by this Agreement,
which records shall be subject to audit by an independent certified public accounting firm
reasonably acceptable to Sterling at any reasonable time during, or within the two years following,
the period being audited. 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.

          (c) Upon the written request of BASF, Sterling shall provide BASF reasonable suitable
temporary office accommodations at the Site for a limited number of BASF personnel or
representatives to audit or review records maintained by Sterling pursuant to this Agreement.

          Section 5.04. Meetings. (a) At each Quarterly Meeting, representatives of the Parties
shall review the operations of the Plasticizers Complex and such other matters as may be determined
to be appropriate by the Parties. At the Quarterly Meeting to be held in October of each Year, the
Parties shall (i) review the Capital Budget and the Maintenance Budget for the ensuing Year, (ii)
review the Fixed Costs and Variable Costs for the immediately preceding 12-month period and (iii)
establish a budget for Fixed Costs and Variable Costs for the following 12-month period; provided,
however, that no Capital Budget, Maintenance Budget or budget for Fixed Costs or Variable Costs
shall reduce, modify or limit in any way BASF’s obligation to pay the actual Capital Expenditures,
Expansion Capital Expenditures, maintenance expenditures, Fixed Costs or Variable Costs incurred
pursuant to this Agreement.

          (b) Sterling shall make its employees and other representatives available to BASF on
reasonable request to discuss the present or proposed operations of the Plasticizers Complex, so
long as such availability does not disrupt the operation of any Unit or the Plant. Representatives
of the Parties shall meet at a mutually acceptable

-41-

 

time and place if either Party gives reasonable prior written notice to the other Party of its
request for a meeting.

          Section 5.05. Technical Advice. (a) BASF shall advise Sterling regarding technical
questions arising in connection with the operation of the Plasticizers Complex, and shall provide
assistance to Sterling in the event of any disturbances at any Unit. Any advice given by BASF
pursuant to this Section 5.05 shall utilize BASF’s technical knowledge and experience, to the
extent that they are suitable for the operation of the Plasticizers Complex; provided, however,
that BASF shall not be obligated to provide Sterling with technical knowledge or experience
acquired by BASF during the term of this Agreement which BASF, in its reasonable judgment,
considers to be a considerable improvement or in respect of which BASF has filed a patent
application. Notwithstanding anything to the contrary contained in this Section 5.05, BASF shall
be under no obligation to provide technical advice that would require in-house work by BASF or its
representatives, including laboratory or pilot plant tests. BASF shall be available to discuss
important technical questions at a meeting between technical experts of BASF and Sterling, either
in Ludwigshafen, Germany or in Texas City, Texas by mutual agreement and at suitable intervals. In
the event that engineering services of BASF are required in connection with Capital Projects or
Expansion Projects, BASF shall, at its sole option and at its sole cost and expense, provide such
engineering services.

          (b) BASF shall render the services contemplated by this Section 5.05 in the best interests of
Sterling and shall apply the same standard of care in rendering such services as it applies in its
own affairs. In the event that BASF fails to fulfill its obligation with such care, (i) BASF shall
be obligated to re-perform such services free of charge, (ii) such re-performance shall be
Sterling’s exclusive remedy for such breach and (iii) BASF shall not incur any further liability
whatsoever related to such matter.

terms have the following respective meanings:

     “Furnishing Party” means, with respect to any Information, the Party that
furnished, or whose Representatives furnished, such Information to the Receiving Party
pursuant to this Agreement.

     “Information” means (i) all information (whether written or oral) furnished
(whether before or after the date hereof) by the Furnishing Party or any of its
Representatives, to the Receiving Party or any of its Representatives for or relating to the

specifications of materials, manuals, technical information plans, drawings and other data
and similar information and records, and (ii) all other information of or concerning the
Furnishing Party or any of its Representatives;

-42-

 

provided, however, that the term “Information” does not include information which (A)
is or becomes publicly available other than as a result of a disclosure by the Receiving
Party or any of its Representatives in violation of this Section 5.06, (B) is known by, is in
the possession of or is or becomes available to the Receiving Party or any of its
Representatives from a source (other than the Furnishing Party or any of its Representatives)
which, to the knowledge of the Receiving Party, is not prohibited from disclosing such
information by a legal, contractual or fiduciary obligation to the Furnishing Party or any of
its Representatives, or (C) has been independently developed by the Receiving Party without
violating any of its obligations under this Section 5.06 and, provided further, that the fact
that information is included in other information which is or becomes otherwise available to
the Receiving Party or its Representatives pursuant to clause (A) or (B) shall not exclude
the balance of such information from the term “Information.”

     “Received Information” means (a) with respect to Sterling, all Information
furnished by, of or concerning BASF or any of its Representatives to Sterling or any of its
Representatives pursuant to this Agreement, and all analyses, compilations, forecasts,
studies or other documents prepared by Sterling or any of its Representatives which contain
or reflect any of such Information, and (b) with respect to BASF, all Information furnished
by, of or concerning Sterling or any of its Representatives to BASF or any of its
Representatives pursuant to this Agreement and all analyses, compilations, forecasts, studies
or other documents prepared by BASF or any of its Representatives which contain or reflect
any of such Information.

     “Receiving Party” means, with respect to any Information, the Party that
received such Information from the Furnishing Party or any of the Furnishing Party’s
Representatives pursuant to this Agreement.

     “Representatives” means, with respect to each Party, such Party’s directors,
officers, employees, partners, agents, Affiliates and non-employee representatives (including
attorneys, accountants, potential sources of financing, underwriters or other financial
advisors, bankers or agents); provided, however, that neither Party shall be deemed to be a
Representative of the other Party.

          (b) The Receiving Party (i) shall keep all Received Information confidential and will not,
except as otherwise provided in this Section 5.06 or with the prior written consent of the
Furnishing Party, disclose any Received Information in any manner or to any Person whatsoever, and
(ii) will not use any Received Information other than in connection with the transactions
contemplated by this Agreement; provided, however, that the Receiving Party may reveal the Received
Information to its Representatives (A) who need to know the Received Information in connection with
the transactions contemplated by this Agreement, (B) who are informed by the Receiving Party of the
confidential nature of the Received Information and (C) who agree to abide by and act in accordance
with the terms of this Section 5.06 to the same extent as if they were parties to this Agreement.
The Receiving Party will cause its Representatives to observe the terms of this Section 5.06 and
will be responsible for any breach of this

-43-

 

Section 5.06 by any of its Representatives to the same extent as if the Receiving Party had
breached this Section 5.06 directly.

          (c) Nothing in this Section 5.06 shall prohibit the Receiving Party or any of its
Representatives from disclosing any Received Information to the extent required by applicable Law,
legal process or other legal compulsion. If the Receiving Party or any of its Representatives are
requested pursuant to, or are required by, applicable Law, legal process or other legal compulsion
to disclose any Received Information, the Receiving Party will give the Furnishing Party prompt
written notice of such request or requirement so that the Furnishing Party may seek a protective
order or other appropriate remedy or waive compliance with the terms of this Section 5.06, and the
Receiving Party will provide reasonable cooperation to the Furnishing Party (at the expense of the
Furnishing Party) to obtain such protective order. If no such protective order or other remedy is
obtained, or the Furnishing Party waives compliance with the terms of this Section 5.06, the
Receiving Party (or such other Person who is requested or required to make such disclosure) will
furnish only that portion of the Received Information which it is advised by its counsel is legally
required to be disclosed and, upon the Furnishing Party’s request and at the expense of the
Furnishing Party, will exercise all commercially reasonable efforts to obtain assurances that
confidential treatment will be afforded the Received Information.

          (d) At any time upon the written request of the Furnishing Party, the Receiving Party will
promptly (i) destroy or deliver to the Furnishing Party, at the Receiving Party’s expense, all
copies of the written Received Information which is in its or its Representatives’ possession, (ii)
destroy all copies of Received Information internally generated by it or materials which are based
upon or incorporate Received Information and (iii) deliver to the Furnishing Party a certificate
executed by one of its duly authorized officers indicating that the requirements of this paragraph
(d) have been satisfied in full; provided, however, that notwithstanding anything to the contrary
contained in this Section 5.06, the Receiving Party may retain one copy of the Received Information
in the files of its legal department, which copy may only be used in case of questions raised as to
the Receiving Party’s compliance with the terms of this Section 5.06. Notwithstanding the return
or destruction of Received Information, the Receiving Party and its Representatives will continue
to be bound by its obligations under this Section 5.06.

          (e) The obligations of the Receiving Party under this Section 5.06 shall terminate with
respect to any given Received Information ten years after the date on which such Received
Information was originally disclosed to the Receiving Party.

          Section 5.07. Restriction on Transfer of Information. Except in connection with a
Plant Disposition, a foreclosure, a sale in lieu of foreclosure or other transfer of the
Plasticizers Complex permitted hereby, Sterling shall not sell, assign or otherwise transfer any
right, title or interest in or to use (except for production of Products at the Plasticizers
Complex) its intellectual property related to the production, sale or marketing of Products without
the prior written consent of BASF.

          Section 5.08. Public Statements. Neither Party shall issue any public announcement or
statement with respect to the transactions contemplated hereby

-44-

 

without the prior written consent of the other Party, unless such announcement or statement is
required by Law or the rules of any securities exchange on which the securities of such Party are
traded.

          Section 5.09. SEC Reports. Sterling shall, at the same time that Sterling makes such
reports available to its stockholders, furnish to BASF all quarterly reports on Form 10-Q, annual
reports on Form 10-K and current reports on Form 8-K filed by Sterling with the Securities and
Exchange Commission.

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

-45-

 

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,

-46-

 

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

-47-

 

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 wells, machines, equipment,
apparatus or lines of pipe or property, freezing of wells, machines, equipment, apparatus or lines
of pipe or property, partial or entire failure of any wells, 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

-48-

 

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 

-49-

 

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

          (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)

-50-

 

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.

     Section 7.02. Effect of Termination. (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

-52-

 

(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

-53-

 

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

-54-

 

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.

-55-

 

          (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.

          (j) Except as required by Law, the Parties shall hold, and shall cause their respective
officers, directors, employees, agents and other representatives to hold, the existence, content
and result of mediation or arbitration in confidence except as may be required by Law or in order
to enforce any award. Each of the Parties shall request that any mediator or arbitrator comply
with such confidentiality requirement.

          (k) Unless otherwise agreed in writing, the Parties will continue to provide service and honor
all other commitments under this Agreement during the course of dispute resolution pursuant to the
provisions of this Section 8.09 with respect to all matters not subject to such Dispute.

          (l) The interpretation of the provisions of this Section 8.09, only insofar as they relate to
the agreement to arbitrate and any procedures pursuant thereto, shall be governed by the United
States Arbitration Act, 9 U.S.C., §§ 1-14, as the same may be amended from time to time, and other
applicable federal Law.

     Section 8.10. Applicable Law. This Agreement And The Rights And Obligations Of
The Parties Hereunder Shall Be Governed By And Construed In Accordance With The Laws Of The State
Of New Jersey, Without Giving Effect To The Conflict Of Law Principles Thereof.

     Section 8.11. Submission to Jurisdiction. Each Party hereby irrevocably submits to
the non-exclusive personal jurisdiction of any state or federal court sitting in the State of New
Jersey, over any claim or dispute arising out of or relating to this Agreement. Each Party hereby
irrevocably agrees that service of process may be made on it by mailing, by certified mail, a copy
of such process to such Party’s registered agent for service of process. Each Party agrees that a
final non-appealable judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.
Nothing in this Section 8.11 shall affect the right of either Party to serve legal process in any
other manner permitted by Law or affect the right of either Party to bring any action or proceeding
in the courts of any other jurisdictions, domestic or foreign.

-56-

 

     Section 8.12. Prevailing Party Costs. Except as otherwise provided in Section 8.09,
if either Party commences an action against the other Party to enforce any of the terms, covenants,
conditions or provisions of this Agreement or because of a breach by a Party of its obligations
under this Agreement, the prevailing Party in any such action shall be entitled to recover its
costs and expenses, including reasonable attorneys’ fees and costs of court, incurred in connection
with the prosecution or defense of such action, from the losing Party.

     Section 8.13. Entire Agreement. This Agreement sets forth all of the promises,
agreements, conditions, understandings, warranties and representations between the Parties with
respect to the matters contemplated hereby, and supersedes all prior agreements, arrangements and
understandings between the Parties, whether written, oral or otherwise. There are no promises,
agreements, conditions, understandings, warranties or representations, oral or written, express or
implied, between the Parties concerning the subject matter hereof except as set forth herein.

          In Witness Whereof, the Parties have caused this Agreement to be executed by their
duly authorized representatives as of the date first above written.

Marine Provisions

     Section 1. Definitions. Capitalized terms used in these Marine Provisions shall have
the following respective meanings, except as otherwise provided herein or as the context shall
otherwise require:

     “Agreement” means the sales, purchase, supply, exchange, conversion, processing,
production or other agreement to which these Marine Provisions are attached or into which
these Marine Provisions are incorporated by reference.

     “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

C-i

 

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,

C-ii

 

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
	 	150 MT/hr	 	 	 	 
	3  2,000 but < 6,000 MTs
	 	100 MT/hr	 	 	 	 
	3  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.

C-iii

 

	 	 	 	 	 	 	 	 	 
	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).

C-iv

 

          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

C-v

 

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

C-vi

 

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.
