          Section 4.2. For planning purposes:

	(a)		at the end of every month, the Buyer shall furnish the Seller with a good faith estimate of the total volumes of HDW Diesel which the Buyer will require during each month for the following three (3) months;
	(b)		at or as soon as practical after the Effective Date and before September 1 of subsequent calendar year of the Term, the Buyer shall furnish the Seller with a good faith estimate of the total volumes of HDW Diesel which the Buyer will require during the succeeding calendar year;
	(c)		at the end of every month, the Seller shall furnish the Buyer with a good faith estimate of the total volumes of HDW Diesel which the Seller expects to purchase and receive from Excel Paralubes during each month for the following three (3) months; and

at or as soon as practical after the Effective Date and before September 1 of subsequent calendar year of the Term, the Seller shall furnish the Buyer with a good faith estimate of the total volumes of HDW Diesel which the Seller expects to purchase and receive from Excel Paralubes during the succeeding calendar year.

          Section 4.3. The HDW Diesel shall meet the specifications established from time to time by Excel Paralubes. If Buyer requests a change in specifications, and if Excel Paralubes is willing to accommodate that request, the price of HDW Diesel sold hereunder shall be adjusted to include cost incurred due to the change. At the Effective Date, the specifications for HDW Diesel are as follows:

PMCC, Flashpoint, degrees F			*	*
D-86 90% Point, degrees F			*	*
ASTM D1500 Color			*	*

          Section 4.4. From time to time, Buyer may request and Seller may supply Supplemental Volume having the same specifications as HDW Diesel. Seller shall supply Supplemental Volume upon Buyer’s request if Excel Paralubes produces Supplemental Volume; the decision to produce or not to produce Supplemental Volume is solely within the discretion of Excel Paralubes and of its partners, including Seller. Neither Seller nor Excel Paralubes has any obligation to produce Supplemental Volume or to sell or deliver Supplemental Volume to Buyer. No Supplemental Volume has been delivered to Seller by Excel Paralubes during 2006 or the first six months of 2007.

ARTICLE V
DELIVERY; TITLE AND RISK OF LOSS

          The HDW Diesel purchased and sold under this Agreement shall be delivered by the Seller, and title to and risk of loss of such HDW Diesel shall pass to the Buyer, at the custody transfer point at which the HDW Diesel leaves Excel Paralubes’ truck loading flange and is delivered into Buyer’s hired truck transports.

ARTICLE VI
MEASUREMENT

          Section 6.1. The volume of HDW Diesel and Supplemental Volumes delivered pursuant to this Agreement shall be determined by metering the HDW Diesel as it is delivered through Excel Paralubes’ truck rack.

          Section 6.2. Supplemental Volumes processed and delivered under this Agreement will be metered by Excel Paralubes and the relevant processing fee will billed according to that metered volume.

ARTICLE VII
PRICE

          Section 7.1. The purchase price per barrel of HDW Diesel (and, to the extent Supplemental Volume is supplied hereunder, of Supplemental Volume) shall be equal to ** plus the blending fee.

          Section 7.2. For purposes of Section 7.1, the “blending fee” shall be $** per gallon of product sold. The blending fee may be recalculated periodically but recalculation may occur no more than once in a twelve-month period.

          Section 7.3. To the extent Supplemental Volume is supplied hereunder, a monthly amount equal to the Supplemental Volume (as determined pursuant to Section 5.2) times the processing fee will be invoiced separately each month. The “processing fee” is based on the actual cost to produce the Supplemental Volumes (an example of this calculation is set forth in Exhibit A).

          Section 7.4. Should any published price referenced in Section 7.1 cease to be published, the Parties will agree upon an acceptable substitute price reference source. All purchase price adjustments contained in Section 7.1 (such as quality and transportation), reflect market and industry practices, conditions and requirements as of the effective date of this Agreement. Material changes in such market and industry factors may necessitate modifications to these purchase price adjustments. In such event, the Parties shall meet and negotiate in good faith modifications to the purchase price adjustments.

ARTICLE VIII
PAYMENT

          Section 8.1. By the fifteenth (15th) calendar day of a month (“Month 2”), Seller shall invoice Buyer for estimated volume of HDW Diesel for Month 2 (the lesser of the volume determined pursuant to Section 4.2(a) or Section 4.2(c)) using the price calculated according to the formula set forth in Section 7.1 for the immediately preceding month (“Month 1”), plus or minus an invoice adjustment to the extent that the volume of HDW Diesel with respect to Month 1 measured pursuant to Article VI multiplied by the price calculated for Month 1 is less than or greater than the amount actually invoiced with respect to Month 1. For example, if in January the volume for January were estimated to be 10,000 barrels pursuant to Section 4.2, and if the price in December were calculated to be $50.00 per barrel, the unadjusted invoice would be $500,000. If in February the volume of Feedstock for January were known to have been 8,000 barrels (and without regard to any other adjustment in the January invoice), the adjustment to the February invoice would be ($100,000).

          Section 8.2. Seller shall invoice Buyer for the actual Supplemental Volume and applicable processing fee (pursuant to Section 7.3) by the fifteenth (15th) calendar day of the month following the month of delivery.

          Section 8.3. Payments shall be made in full, by wire transfer no later than three (3) business days after receipt by Buyer of the invoice, without any adjustments, discounts or setoffs, except in cases of bona fide disputes, in which cases only the disputed amount will be withheld. Such payments shall be without prejudice to any claim for damages or any other right under this Agreement or applicable law. In the event Buyer fails to make any payments on or before the due date, Seller shall have the right to charge interest from the due date on the amount of the overdue payment at a per annum rate which shall be the lower of (a) the prime rate plus two percent (2%), or (b) the maximum interest rate permitted by law. Prime rate shall mean, for any day, the rate of interest announced by ▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇ Bank (or its successors or an acceptable substitute agreed to by the Parties) as its prime lending rate.

          Section 8.4. The Seller reserves the right to withhold delivery of HDW Diesel to the Buyer at any time the Buyer’s account becomes more than thirty (30) days past due.

ARTICLE IX
CLAIMS

          Section 9.1. The Seller shall have no liability to the Buyer for any defect in the quality of the HDW Diesel delivered pursuant to this Agreement unless:

	(a)		the Buyer gives the Seller written notice of the Buyer’s claim of defect within ninety (90) days after delivery of the HDW Diesel or, with respect to a latent defect, within seven (7) days after the Buyer has discovered such latent defect, but in no event more than one hundred twenty (120) days after delivery; and
	(b)		the Seller is given reasonable opportunity to inspect the HDW Diesel or analyze the Buyer’s retained samples, which analysis must occur within fifteen (15) days after Seller receives notice of defect.

          Section 9.2. Nothing contained in this Article shall limit the defenses which the Seller may have against such claims.

ARTICLE X

ARTICLE XIII
FORCE MAJEURE

          Section 13.1. Force Majeure.

ARTICLE XIV
EVENT OF DEFAULT

          Section 14.1. Event of Default. The failure of Buyer or Seller to perform or comply with any material term or condition of this Agreement shall constitute an Event of Default hereunder unless cured pursuant to Section 14.2.

3. HAZARDS IDENTIFICATION

Potential Health Effects

Eye: Contact may cause mild eye irritation including stinging, watering, and redness.

Skin: Contact may cause mild skin irritation including redness, and a burning sensation. Prolonged or repeated contact can worsen irritation by causing drying and cracking of the skin leading to dermatitis (inflammation). No harmful effects from skin absorption are expected.

Inhalation (Breathing): No information available. Studies by other exposure routes suggest a low degree of toxicity by inhalation.

Ingestion (Swallowing): No harmful effects expected from ingestion. ASPIRATION HAZARD — This material can enter lungs during swallowing or vomiting and cause lung inflammation and damage.

Signs and Symptoms: Effects of overexposure may include irritation of the digestive tract, irritation of the respiratory tract, nausea, diarrhea, transient excitation followed by signs of nervous system depression (e.g._; headache, drowsiness, dizziness, loss of coordination, disorientation and fatigue).

Cancer: There is inadequate information to evaluate the cancer hazard of this material. See Section 11 for information on the individual components, if any.

Target Organs: Not Evaluated

Developmental: No data available for this material.

Pre-Existing Medical Conditions: Conditions aggravated by exposure may include skin disorders.

4. FIRST AID MEASURES

Eye: If irritation or redness develops, move victim away from exposure and into fresh air. Flush eyes with clean water. If symptoms persist, seek medical attention.

Skin: Remove contaminated shoes and clothing and cleanse affected area(s) thoroughly by washing with mild soap and water. If irritation or redness develops and persists, seek medical attention.

Inhalation (Breathing): If respiratory symptoms develop, move victim away from source of exposure and into fresh air. If symptoms persist, seek medical attention. If victim is not breathing, clear airway and immediately begin artificial respiration. If breathing difficulties develop, oxygen should be administered by qualified personnel. Seek immediate medical attention.

Ingestion (Swallowing): Aspiration hazard: Do not induce vomiting or give anything by mouth because this material can enter the lungs and cause severe lung damage. If victim is drowsy or unconscious and vomiting, place on the left side with the head down. If possible, do not leave victim unattended and observe closely for adequacy of breathing. Seek medical attention.

5. FIRE-FIGHTING MEASURES

Flammable Properties:

		Flash Point:		>220°F / 104°C
		Test Method:		▇▇▇▇▇▇-▇▇▇▇▇▇▇ Closed Cup (PMCC), ASTM D93, EPA 1010
		OSHA Flammability Class:		Not applicable
		LEL%:		0.58
		UEL%:		No data
		Autoignition Temperature:		442°F / 228°C

Unusual Fire & Explosion Hazards: This material may burn, but will not ignite readily. Vapors are heavier than air and can accumulate in low areas. If container is not properly cooled, it can rupture in the heat of a fire.

Extinguishing Media: Dry chemical, carbon dioxide, foam, or water spray is recommended. Water or foam may cause frothing of materials heated above 212° F. Carbon dioxide can displace oxygen. Use caution when applying carbon dioxide in confined spaces.

MSDS Code: 776548				Page 3/6
Status: Final				Date of Issue: 20-Dec-2005

Fire Fighting Instructions: For fires beyond the incipient stage, emergency responders in the immediate hazard area should wear bunker gear. When the potential chemical hazard is unknown, in enclosed or confined spaces, or when explicitly required by DOT, a self contained breathing apparatus should be worn. In addition, wear other appropriate protective equipment as conditions warrant (see Section 8).

Isolate immediate hazard area, keep unauthorized personnel out. Stop spill/release if it can be done with minimal risk. Move undamaged containers from immediate hazard area if it can be done with minimal risk.

Water spray may be useful in minimizing or dispersing vapors and to protect personnel. Cool equipment exposed to fire with water, if it can be done with minimal risk. Avoid spreading burning liquid with water used for cooling purposes.

6. ACCIDENTAL RELEASE MEASURES

This material may burn, but will not ignite readily. Keep all sources of ignition away from spill/release.

Stay upwind and away from spill/release. Notify persons down wind of the spill/release, isolate immediate hazard area and keep unauthorized personnel out. Stop spill/release if it can be done with minimal risk. Wear appropriate protective equipment including respiratory protection as conditions warrant (see Section 8).

Prevent spilled material from entering sewers, storm drains, other unauthorized drainage systems, and natural waterways. Dike far ahead of spill for later recovery or disposal. Spilled material may be absorbed into an appropriate absorbent material.

Notify fire authorities and appropriate federal, state, and local agencies. Immediate cleanup of any spill is recommended.

7. HANDLING AND STORAGE

Handling: Do not enter confined spaces such as tanks or pits without following proper entry procedures such as ASTM D-4276 and 29CFR 1910.146. The use of appropriate respiratory protection is advised when concentrations exceed any established exposure limits (see Sections 2 and 8).

Do not wear contaminated clothing or shoes. Use good personal hygiene practices.

“Empty” containers retain residue and may be dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose such containers to heat, flame, sparks, or other sources of ignition. They may explode and cause injury or death. “Empty” drums should be completely drained, properly bunged, and promptly shipped to the supplier or a drum reconditioner. All containers should be disposed of in an environmentally safe manner and in accordance with governmental regulations.

Storage: Keep container(s) tightly closed. Use and store this material in cool, dry, well-ventilated areas away from heat and all sources of ignition. Store only in approved containers. Keep away from any incompatible material (see Section 10). Protect container(s) against physical damage.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION

Engineering controls: If current ventilation practices are not adequate to maintain airborne concentrations below the established exposure limits (see Section 2), additional engineering controls may be required.

Personal Protective Equipment (PPE):

Respiratory: The use of respiratory protection is advised when concentrations are expected to exceed the established exposure limits (see Section 2). Depending on the airborne concentration, use a respirator with appropriate cartridges (NIOSH certified) or supplied-air equipment.

Skin: The use of gloves impervious to the specific material handled is advised to prevent skin contact, possible irritation, and skin damage (see glove manufacturer literature for information on permeability). Depending on conditions of use, apron and/or arm covers may be necessary.

Eye/Face: Approved eye protection to safeguard against potential eye contact, irritation, or injury is recommended. Depending on conditions of use, a face shield may be necessary.
