7.2 Initial Balance - Both EDNLP and BMS have previously invested in Catalyst, comprised of Precious Metals, which have been or continue to be used in the production process of the Nitric Acid Facility, represented by an initial balance which represents each party’s total unrecovered investment in the Catalyst to date. The BMS initial Catalyst balance contains: (i) the amount of Catalyst purchased as part of the Initial Capital Investment; (ii) plus the quantity of Precious Metals paid for by BMS to replenish or repair Catalyst subsequent to the start up of the Nitric Acid Facility up to the Commencement Date of this Agreement; (iii) less any sludge or other Precious Metals recoveries from the process credited to BMS subsequent to the start up of the Nitric Acid Facility up to

- 51 -

the Commencement Date of this Agreement; (iv) less any metals sold by EDNLP on behalf of BMS prior to the Commencement Date.

The EDNLP initial Catalyst balance contains: (i) that amount of Catalyst paid for by EDNLP, for which EDNLP has not been reimbursed, subsequent to the start up of the Nitric Acid Facility up to the Commencement Date of this Agreement; (ii) less any sludge or other Precious Metals recoveries from the process credited to EDNLP subsequent to the start up of the Nitric Acid Facility up to the Commencement Date of this Agreement; (iv) less any metals allocated to EDNLP and sold by EDNLP prior to the Commencement Date.

Initial balances shall be adjusted for any Catalyst credits or debits resulting from the reconciliation of the refining and Recovery of the Catalyst in use as of the Commencement Date.

7.3 Additions – All Catalyst or Precious Metals purchased under this Agreement shall be added to the Catalyst balance of BMS.

7.4 Recoveries - During the effective period of this Agreement, EDNLP’s third party provider shall conduct, at EDNLP’s request, attempted Recoveries by (i) removing sludge or Precious Metals found within the Nitric Acid Facility, if any, and (ii) having the sludge or Precious Metals processed and refined to recover any Precious Metals. Upon termination or expiration of this Agreement and continuing for the twenty (20)

- 52 -

year term of this Section 7, the attempted Recovery shall be conducted by (i) removing sludge or Precious Metals found within the Nitric Acid Facility, if any, and (ii) having the sludge or Precious Metals processed and refined to recover any Precious Metals.

Any Precious Metals Recovery from the production process at the Nitric Acid Facility shall be allocated among the parties based on the then-current EDNLP Catalyst Balance and BMS Catalyst Balance. For example, if 100 ▇▇▇▇ ounces of Precious Metals are recovered and the EDNLP Catalyst Balance is 1,000 ▇▇▇▇ ounces and the BMS Catalyst Balance is 9,000 ▇▇▇▇ ounces, then 90 ▇▇▇▇ ounces would be allocated to the BMS Catalyst Balance, because the BMS Catalyst Balance represents 90% of the sum of the BMS Catalyst Balance and the EDNLP Catalyst Balance. The remaining 10 ▇▇▇▇ ounces would be allocated to the EDNLP Catalyst Balance.

During the term of this Agreement, upon receiving the Precious Metals from the Recovery, EDNLP shall, based on the allocation method described above and at BMS’s option, either (i) transfer to BMS its allocation of the actual metals; or (ii) sell the BMS allocation of Precious Metals at the then current market price and provide BMS with the proceeds from such sale, as directed by BMS. After the expiration or termination of this Agreement, upon receiving the Precious Metals from the Recovery, BMS shall, based on the allocation method described above and at

- 53 -

EDNLP’s option, either (i) transfer to EDNLP its allocation of the actual metals; or (ii) sell the EDNLP allocation of Precious Metals at the then current market price and provide EDNLP with the proceeds from such sale, as directed by EDNLP. During the effective term of this Agreement and upon termination or expiration of this Agreement, EDNLP shall bear the appropriate proportion of Recovery charges based on the allocation method described above.

7.5 Reductions – Each party’s Catalyst balance shall be decreased by the ▇▇▇▇ ounces of Precious Metals recovered under the previous section, if any.

7.6 Catalyst Balance - BMS shall maintain, or instruct EDNLP to maintain, balances of each Precious Metal used in the Catalyst in ▇▇▇▇ ounces. The BMS Catalyst Balance shall be calculated by increasing the initial catalyst balance by the additions referred to above, minus the reductions referred to above. The EDNLP Catalyst Balance shall be calculated by reducing the initial Catalyst balance by the reductions referred to above.

7.7 Schedule – Any attempt to recover Catalyst or to remove sludge at the Nitric Acid Facility shall require the prior written consent of BMS. EDNLP shall further have the right, and BMS shall provide reasonable notice to EDNLP of its occurrence, to direct a mutually agreed upon third party

- 54 -

observer to witness any Catalyst sludge or Precious Metals recoveries performed by BMS in accordance with this Section 7 of this Agreement. The parties shall be required to employ industry standards to reach a settlement for each sludge or Precious Metals recovery.

7.8 Settlement - Upon the expiration of this Section 7 which has a term of twenty years, the parties agree to negotiate in good faith to reach a settlement as to the remaining EDNLP Catalyst Balance. The parties recognize that the value of this settlement shall be dependent on the timing of the recoveries, the then-current market value of the Precious Metals, the expected recovery rates, and the recoveries previously credited to EDNLP during the term of this Section 7 of this Agreement.

Upon termination of this Agreement, any amounts paid by BMS under Section 4.2 as a prepayment for Catalyst or Precious Metals and not used for refining or refabricating of Catalyst, and that has not been reimbursed by EDNLP to BMS under Section 5.1, shall be returned to BMS within thirty (30) days of the termination date.

SCHEDULE 1

Utilities and Chemical Additives Supplied by BMS

(A) - Water

Plant water:

The Coastal Water Authority supplies raw water to the Bayer Baytown Plant through the canal which runs to the east of the site. This water flows either directly to the south plant water system or to one of two 7.5 million gallon reservoirs at the east plant water system. The reservoirs provide both reserve capacity for the fire water system and storage of raw water to be processed in the east plant water system. At both plant water systems, the raw water is chemically treated prior to being introduced into the systems’ clarifiers. The clarified water is then sent through a set of sand filters. The sand filter effluent is stored in either a 1 million gallon tank at the south system or a 1.5 million gallon storage tank at the east system. Under normal operations, plant water is distributed to the site at approximately 135 PSIG.

Typical EDNLP monthly volume is estimated to be 20 million gallons at an average rate of approximately 450 gallons per minute. The EDNLP water consumption shall not exceed a maximum rate of 870 gallons per minute. The maximum plant water system pressure (system design pressure) is 145 PSIG.

Demineralized water:

Plant water is initially run across one of four carbon beds to reduce organics and improve turbidity. The filtered water then travels through one of four demineralized water trains. With each train, the filtered water is first sent across the cation exchanger where the positive ions are removed. The decationized water then flows across the anion exchanger where the negative ions are removed. Train 4 utilizes a decarbonator (removes CO2) prior to a series of weak and strong anion beds. The effluent from the anion bed then travels through the mix bed exchanger containing both types of resin which produces a virtually ion free water. This water is then sent to the 300,000 gallon storage tank. Under normal operations, demineralized water is distributed to the site at approximately 120 PSIG from BMS Environmental Control Department and Utilities (ECDU). The Chlor Alkali unit also exports on average approximately 350 to 400 gallons per minute of demineralized water into the plant supply system.

The normal maximum EDNLP consumption rate is 40 gallons per minute. Demineralized water can also back up the boiler feed water supply. The maximum demineralized water pressure (system design pressure) is 140 psig.

In the event BMS cannot provide boiler feed water meeting the specifications and quantities specified, EDNLP shall be entitled to use demineralized water for makeup up to a maximum quantity of 275 gallons per minute, subject, however, to reasonable allocation among

BMS and its guest facilities in the event of a shortage of such demineralized water.

Fire water:

The Bayer Baytown Plant’s fire water system is supplied from two locations at the site (east or west). At the east system, raw water from the site’s reservoirs is supplied to a combination of diesel and electric motor driven pumps. These pumps supply the main system header, which encompasses the entire site. Pressure is maintained in this header at approximately 125 PSIG by the electric "jockey" pump. A decrease in the header pressure will automatically start the diesel fire water pumps. An emergency fire water reserve of approximately 2.4 million gallons is maintained at the east system. The west system has a dedicated 2.0 million gallon capacity when at normal operating level. This system is equipped with an electric motor driven "jockey" pump to maintain header pressure. The west system also has two diesel driven fire water pumps to maintain system pressures in the event of a loss of power to the area.

BMS will supply fire water to the Battery Limits of the Nitric Acid Facility at a sufficient pressure and flow rate to meet EDNLP design and insurance requirements of the Nitric Acid Facility.

Potable water:

The Bayer Baytown Plant receives potable water through of a 12-inch diameter header from the City of Baytown. Under normal operations, the potable water is distributed at approximately 100 PSIG using one of the two booster pumps equipped with variable speed drives. During freeze precautions the larger of the two potable water booster pumps is used to meet demand at approximately 135 PSIG. In the event of an electrical failure, the emergency potable water diesel pump will automatically start to maintain system pressures. Potable water is to be used exclusively to supply safety showers, eye wash stations, and routine potable water needs in the plant.

Typical monthly volume is estimated to be approximately 5,000 gallons. Potable water consumption shall not exceed a maximum monthly rate of 20,000 gallons. Potable water shall meet the minimum municipal guidelines. The maximum pressure (system design pressure) is 150 PSIG.

Boiler feed water:

The condensate returned from the steam users at the site is collected in one of two drums where flash steam is recovered. The condensate is then sent to a deaerator where the recovered flash steam is used to strip the non-condensable gases and heat the water to its saturation point. Chemicals are added at this point to remove the remaining oxygen and limit system piping corrosion. Under normal operations boiler feed water supply to EDNLP operates in the range from 150 to 230 PSIG. The boiler feed water system design pressure is 230 PSIG.

(B) Nitrogen:

The Bayer Baytown Plant is supplied from a single supplier through both of the sites two metering stations (south and east). The nitrogen from the east metering station is supplied at approximately 140 PSIG to the site. Nitrogen from the south metering station is supplied at both 140 PSIG and approximately 400 PSIG. The 400 PSIG nitrogen system is to be used solely for the site’s emergency shutdown systems.

The continuous usage is estimated to be minor. Monthly volume on an intermittent basis is approximately 15,000 - 25,000 SCF. The maximum pressure (system design pressure) is 150 PSIG for the 140 PSIG system.

C)Instrument/plant air:

Plant and instrument air is supplied to the Bayer Baytown Plant via five air compressors operated in parallel at one of two locations (west and north systems). At the west air system, the compressed air from any of the three compressors in service enters the adjacent air receivers that act as pulsation dampeners. The compressed air is then sent through a set of air dryers prior to being distributed to the plant air or instrument air distribution systems. The discharge piping is arranged so that any compressor can feed either air header. At the north air system, the compressed air exits one of the two compressors, then enters the adjacent air dryers. It is then sent to the adjacent air receiver prior to being sent to either the plant or instrument air headers. Both instrument and plant air are distributed above 90 PSIG and at a -40 F dew point. In the event of pressure loss in the instrument air system, there are two emergency nitrogen connections to supply nitrogen to the instrument air header and maintain system pressure.

Typical volume during truck unloading is estimated to be 300 SCFM. Typical monthly volume is expected to be 1.5 - 2.5 million SCF at an average rate of approximately 50 SCFM. The maximum plant/instrument air pressure (system design pressure) is 120 PSIG.

During the plant start-up, plant air must be used to seal the compressor train until minimum governor speed is reached. Plant air consumption shall not exceed a maximum rate of 700 SCFM during process start-up.

(D)Steam:

Steam at the Bayer Baytown Plant is supplied at three pressures (720 PSIG, 630 PSIG, and 150 PSIG). The majority of 720 PSIG steam is supplied to the site by the Calpine Cogeneration Unit located on the north side of the site. Typically, the steam supplied by this unit is letdown through the site’s letdown stations for use by the production units. The 630 PSIG steam is supplied either through one of the two 720 PSIG to 630 PSIG steam letdown stations or produced by one of the site’s waste heat boilers. The letdown stations operate on pressure control and supply 630 PSIG steam as needed to satisfy production demands. The site’s 150 PSIG steam is supplied through one of the two

630 PSIG to 150 PSIG steam letdown stations or one of the site’s waste heat boilers.

Except for each start-up and shutdown of the Nitric Acid Facility, during normal operation EDNLP will not consume steam from BMS. EDNLP shall export approximately 30,000 to 60,000 pounds of steam per hour to BMS. The EDNLP export steam pressure will be adequate to supply the site 630 PSIG steam system. All steam treatment must be compatible with the BMS steam treatment system.

(E) Natural gas:

Natural gas to Bayer Baytown Plant is supplied by a primary and secondary supplier at each of the site’s two metering stations. Natural gas from the primary supplier is distributed to the site from both the east and south metering stations at approximately 90 PSIG. The secondary supplier is used solely as a back-up at the south metering station and will automatically begin supplying gas if the system’s pressures fall below 80 PSIG.

No natural gas is consumed in the nitric acid manufacturing process. Natural gas may be used in the laboratory or in the offices and buildings for heat and air conditioning. Natural gas consumption is estimated to average less than 1 SCFM.

(F) Chlorine

Chlorine is used for water treatment at the cooling tower. Based on the anticipated blowdown rate, chlorine consumption will average 100 pounds per day, with a peak consumption of 170 pounds per day. The chlorine will be standard commercial grade with a minimum of 99.5% chlorine by weight. The maximum chlorine supply pressure (system design pressure) is 150 PSIG.

(G) 32% caustic (32% NaOH, 32% sodium hydroxide)

32% caustic will be used primarily for neutralization. Caustic consumption will average 25-30 pounds per day on a 100% basis with peak consumption of 1,500 pounds per day. BMS supplies 32% membrane grade caustic solution to EDNLP. The maximum supply pressure (system design pressure) is 175 PSIGS.

(H) 98% sulfuric acid

BMS provides 98% sulfuric acid deliveries to EDNLP for the cooling tower via tank trucks. Trucks are typically scheduled on Wednesday of each week. The supplier monitors the sulfuric acid tank level. Based on this information 98% sulfuric acid deliveries are scheduled by BMS as needed. EDNLP may also contact the BMS Environmental Control Department and Utilities to be put on the schedule for the next delivery, at least one day in advance. Approval of the Certificate of Analysis is done by the polyurethane quality area prior to delivery to EDNLP. At the end of the month, BMS informs EDNLP of the amount of 98% sulfuric acid delivered during the month. EDNLP reports this number to the appropriate accounting department, which is then included in the monthly Variable Cost Component.

SCHEDULE 5

WASTE

BASIS:

1.	For pH control of Routine Process Waste, Initial Stormwater and Additional Stormwater, EDNLP will neutralize with caustic soda.

2.	EDNLP will discharge Cooling Tower Blowdown into the Bayer Baytown Plant's cooling tower blowdown header.

3.	The overhead waste water header backpressure is up to 50 P.S.I.G. during rains.

4.	Normal flow rates below are based on Nitric Acid Facility production of 443,000 short tons of nitric acid (100% basis) a year.

5.	EDNLP will continuously monitor pH and flow to waste water header as well as pH of Additional Stormwater to BMS's storm sewer.

6.	EDNLP must keep Uncollected Stormwater free of contaminants.

Waste Stream	Quality	Peak Flow	Normal Flow
Flow to Cooling Tower Blowdown header, gpm	pH range 7.5 - 8.0	138	85
	Anticipated metal levels:1 Cr 0.013 lb/day Cu 0.045 lb/day Ni 0.014 lb/day Pb 0.007 lb/day Zn 0.767 lb/day
Flow to Waste Water header
Routine Process Waste, gpm Washdown Water Lab Samples Process Purges Leaks Boiler Blowdown	warranted pH range of 5.0 to 8.0 * Intermittent flow from Waste Water Sump to header when pumping rate is about 100 gpm.	150	15
Total Flow to Waste Water header, gpm

______________

Metal levels of this water shall be no more than twice the anticipated metal levels.
