FRONTIER PRODUCTS OFFTAKE AGREEMENT
EL DORADO REFINERY
 
AGREEMENT dated as of October 19, 1999 by and between Frontier Oil and Refining Company, a Delaware corporation ("Frontier") and Equiva Trading Company, a Delaware general partnership ("ETCo"), but effective as of the Effective Time defined in the Asset Purchase and Sale Agreement dated even date herewith among Equilon Enterprises LLC, Frontier El Dorado Refining Company and Frontier Oil Corporation. Frontier and ETCo are sometimes referred to herein individually as a Party and collectively as the Parties.
 
WITNESSETH:
 
WHEREAS, Frontier desires to sell certain products in connection with Frontier El Dorado Refining Company's operations at the El Dorado Kansas Refinery, in Butler County Kansas (the "Refinery") all upon the terms and conditions set forth herein; and
 
WHEREAS, ETCo is willing to buy those products in the quantities, at the price, and on the terms and conditions set forth herein;
 
NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein, the Parties agree as follows:
 
1.    DEFINITIONS. Capitalized terms shall have the meaning defined herein. As used in this Agreement, the following terms shall have the meanings set forth below:
 
Affiliate shall, with respect to ETCo, mean any of its members or owners, and their respective parents, subsidiaries, affiliates, or joint venturers, or any other Person directly or indirectly controlling, controlled by, or under common control with, ETCo; with respect to Frontier, the term shall mean any Person directly or indirectly controlling, controlled by, or under common control with, Frontier. For purposes of this definition, "control" shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of an entity, whether through the ownership of voting securities or interests or otherwise.
 
Person means an individual, corporation, partnership, association, trust, limited liability company or any other entity or organization, including a government or political subdivision or agency, unit or instrumentality thereof.
 
2.    PURCHASE OF PRODUCTS.
 
To the extent provided in and subject to the terms and conditions of this Agreement, ETCo shall buy from Frontier and Frontier shall sell to ETCo the products as listed below ("Products") which are produced at the Refinery during the term hereof on the terms and conditions in the attached Schedules, including volumes, price formulae, and other terms:
 
(a) Off-Take Volumes in accordance with Schedule A;
 
(b) Mogas in accordance with Schedule B;
 
(c) Diesel in accordance with Schedule C;
 
(d) Avjet in accordance with Schedule D;
 
(e) #1 Fuel Oil in accordance with Schedule E; and
 
(f) Products listed in subsections (b), (c), and (e) in excess of the MPF and other products not listed may, but are not required to be, marketed in accordance with Schedule F.
 
Products shall be delivered in compliance with all federal, state, and local regulations applicable at the designated custody transfer point. Product specification changes due to any federal, state, or local regulations shall override the specification requirements in all schedules and exhibits.
 
3.    PRICING.
 
(a) Pricing for each Product purchased and sold is provided in the appropriate Schedule attached hereto. If the Parties agree that a certain price shall be determined using (in whole or part) a particular published price and that publication ceases during the term of that Schedule, the Parties shall negotiate a substitute method for determining the price based upon an arms-length, third-party price for a like product and volume which should not exceed the third-party price duly taking into account quality and transportation differentials.
 
(b) The initial publication used for pricing Products will be Platt's Oil Service.  Each Party hereto agrees that neither it nor any of its Affiliates will attempt to affect the Platt's quoted prices in such a manner as to unfairly gain an advantage in the pricing formulas used in this Agreement.  Each Party has the right, upon request to the other Party, to audit all data supplied by the other Party or any of its Affiliates to Platt's Oil Service (or future substituted publications).
 
4.    DELIVERY AND NOMINATION.
 
        (a) On or before the 15th of each calendar month, Frontier will submit to ETCo a Monthly Product Forecast ("MPF”). The MPF is the volume of Products estimated to be produced at the Refinery during the following month less Frontier retained volumes for that month as provided for in Schedule A. ETCo must purchase all volumes of Products included in the MPF. Frontier will also provide an estimate for informational purposes only of the Products to be produced for the two months following the MPF month.
 
(b) If Frontier exceeds the MPF by more than three percent in three consecutive months, the parties shall need to discuss the inaccuracy of the forecasts. Where the actual production exceeds the MPF for three consecutive months by three percent, for each consecutive month following such three month period, Frontier shall pay ETCo five cents per barrel for every barrel produced in excess of the MPF.
 
(c) Any known planned outage at the Refinery shall be reported by Frontier within ninety (90) days prior to the month of activity. Product deliveries to ETCo and Frontier retained volumes shall be pro-rated to the average of the previous ninety days activity during the outage period.
 
(d) Subject to the provisions of Sections 4(c) and 13 hereof, if Frontier is unable to deliver the volumes for each Product in the MPF from its production volume at the Refinery, Frontier may elect to purchase additional product and deliver same to ETCo to cover any shortfall of production. If Frontier fails to deliver the MPF volumes (through its production or third party purchases), ETCo will be entitled to purchase the deficient volumes at market-based prices and to deduct the actual value from the formula value specified on that Product Schedule, and debit or credit the difference to Frontier.
 
(e) Products shall be delivered to the pipeline, rack, and terminal locations as specified in each Schedule. Product deliveries and liftings shall be the MPF, equally divided by week unless otherwise agreed in writing by the Parties. Volumes tendered but not lifted will be sold in storage at the price posting of the commitment period provided that all volumes tendered by Frontier will be lifted by ETCo within three days after tender, except to the extent all the pipelines will not accept delivery. Other Products delivered or lifted will be sold on a mutually agreed basis as per Schedule F.
 
(f) Deliveries of Frontier retained volumes into the Denver or Colorado Springs markets shall not, in any month of activity, exceed by more than five percent the contractual volume for those markets specified in Schedule A. Retained volumes supplied in excess of the contractual volume shall be delivered by Frontier into Williams, Kansas City or Kaneb pipelines, or the El Dorado truck rack.
 
(g) On or about sixty (60) days prior to each calendar year-end, ETCo and Frontier shall revalidate or adjust the product off-take volumes for the following year as per the procedures set forth in Schedule A.
 
(h) Frontier shall use the Equilon Pipeline system for any distribution, exchange, or third-party sale of all Products not sold to ETCo where (i) use of such pipeline is practical, (ii) that pipeline cost is equal to or less than the alternative method, and (iii) Frontier's customers are not adversely affected by the use of Equilon’s systems.
 
5.    PRINCIPLES OF COOPERATION.
 
(a) Each Party shall communicate, in a timely manner, to the other any anticipated significant increase or decrease in the availability of or purchase- requirements for a Product. The stated or subsequently communicated quantities shall be for information purposes only and shall not constitute minimum or maximum quantities to be bought or sold hereunder.
 
(b) Each Product shall meet the specifications set forth in the Schedules for that Product. If Frontier is unable to meet those specifications at any time, Frontier shall notify ETCo as soon as possible. ETCo, after reviewing the properties of Product stream, may, in its discretion, either reject the Product stream or agree to accept the Product stream by temporarily agreeing to a waiver of the specification at a mutually agreed price. Unless otherwise agreed in writing, if ETCo accepts any nonspecification Products, ETCo shall have no further recourse to Frontier for the nonspecification Products. ETCo's rejection of off specification Products streams shall not relieve Frontier of its obligation under subsection 4(d).
 
(c) All claims of ETCo with respect to quality of each Product sold and delivered pursuant to this Agreement shall be deemed waived and forever barred unless ETCo gives written notice to Frontier of the nature and details of the claim within sixty (60) days after receipt by ETCo.
 
6.    TAXES.
 
(a) In addition to all other amounts payable by either Party to the other under this Agreement, ETCo shall report and pay all applicable taxes, assessments, or other charges which may be imposed on or with respect to or measured by delivery or sale of a Product from Frontier. In those cases where the law or ordinance imposes upon Frontier the obligation to report or pay those taxes, assessments, or other charges, ETCo shall reimburse Frontier upon receipt of its invoice for the amount of the taxes, assessments, or other charges. Frontier shall assign, transfer, or credit to ETCo all of the available Foreign Trade Zone (FTZ) duty drawback associated with the Avjet received under this Agreement by ETCo.
 
(b) ETCo shall furnish Frontier with proper evidence of tax exemption, as required or permitted by law, to establish exemption from taxes, assessments, or other charges now in effect or hereafter imposed on or with respect to the delivery or sale of Products.
 
(c) Notwithstanding the provisions of 6(a) and 6(b), each Party shall pay all federal, state, and local income taxes and state franchise, license, and similar taxes required for the maintenance of corporate existence or any similar taxes, assessments, and charges imposed on the Party, without right of reimbursement or contribution from the other Party.

7.    PAYMENT.
 
(a) ETCo shall pay Frontier on a weekly basis for each Product provided by Frontier. Frontier shall transmit its invoices to ETCo weekly based on estimated prices for the Product. Any pricing discrepancy shall be corrected by invoice by the 5th business day of the calendar month following the month of delivery. Each invoice shall list separately the quantities of the Products. A reference to each bill of lading and the price for each Product shall be included. Payment by ETCo shall be made by electronic funds transfer, within two Business Days of receipt of the invoice, to Frontier's account at a bank nominated by Frontier. Any late payments will bear interest at LIBOR + 1%.
 
(b) If ETCo objects to any portion of any invoice, ETCo shall pay the amount mutually agreed by Frontier and ETCo or in the absence of such agreement the undisputed amount and one half of the disputed amount when due and shall give written notice to Frontier, no later than sixty (60) days after the date of the invoice, of the reason for objection to the contested amount. The notice shall identify the disputed invoice, state the amount in dispute, and state the grounds on which the objection is based. No adjustment shall be considered or made for disputed charges unless notice is given as provided above. After notice by ETCo, Frontier shall use their best efforts to resolve the objection within sixty (60) days as per Section 16. The existence of any dispute as to an invoice shall in no way affect the obligations of ETCo and Frontier to continue to provide products or to receive products pursuant to this Agreement.
 
(c) ETCo shall have the right, at its own cost, to inspect and audit Frontier's books and accounts (wherever located or owned) as to the volume or price calculation used to invoice a product for any calendar year, provided that the audit commences no later than two years following the end of the calendar year. The right to audit shall not permit ETCo to otherwise audit the financial records or the assets of Frontier other than meters used to determine the volume of a product. Any audit shall be pursued diligently and completed no later than two months after its commencement, and any claim must be made in writing within sixty (60) days following completion of the audit. ETCo shall give Frontier thirty (30) days notice of its intent to initiate a particular audit, as well as a written list describing the contents of any files or computer retrievals necessary for the audit.
 
(d) Frontier shall have the right, at its own cost, to inspect and audit ETCo's books and accounts (wherever located or owned) as to the volume or price calculation for Products for any calendar year, including volumes purchased by ETCo from third parties pursuant to Section 4 above to cover shortfall in MPF deliveries, provided that the audit commences no later than two years following the end of the calendar year. Any audit shall be pursued diligently and completed no later than two months after its commencement, and any claim must be made in writing within sixty (60) days following completion of the audit. Frontier shall give ETCo thirty (30) days notice of its intent to initiate a particular audit, as well as a written list describing the contents of any files or computer retrievals necessary for the audit.
 
      (e) Frontier and ETCo acknowledge and agree that each of them and their respective Affiliates are entitled to certain offset rights with respect to payments due and owing under this Agreement, which may permit them to offset against payments due and owing under that certain Foreign Crude Supply Agreement between Frontier Oil and Refining Company and Equiva Trading Company dated even date herewith and the Cogeneration Sublease between Equilon Enterprises LLC and Frontier El Dorado Refining Company dated even date herewith in accordance with the procedures set forth in Schedule H, which is incorporated by reference herein.
 
    8.     TERM.
 
This Agreement shall have a primary term of fifteen (15) years, effective as of the Effective Time. Upon expiration of the primary term, the Agreement will automatically rollover on a year-to-year evergreen basis unless either Party advises the other Party of their intent to terminate this Agreement in writing no less than one year prior to the end of the primary term. After the primary term, this Agreement may be terminated by either Party at any time by giving the other Party one year advance notice of termination.
 
The initial pricing premises shall have a term of one year, and then be negotiated annually, if required, by mutual agreement. Either Party will have the right to call for a renegotiation of prices upon structural change to the refinery, regulatory requirements, Product specifications, or a material shift in market conditions (other than a short-term or temporary aberration in the market). If the Parties fail to reach agreement with respect to a new price structure or price reference within sixty (60) days from the commencement of negotiations with respect thereto, either Party may submit the question for resolution pursuant to the Dispute Resolution provisions attached hereto as Schedule G. The Arbitrator(s) shall make the decision retroactive to the date upon which the questions was submitted and within twenty (20) days of the receipt of any decision, an adjusting payment shall be made by Frontier or ETCo, as the case may be.
 
    9.     METERING AND QUALITY I ESTING.
 
(a) Metering.
 
(i) The quantities of each Product sold shall be measured by a meter(s) or other appropriate device (the Meter) located at or near the delivery point(s) for such Product. Frontier shall read the Meter on a regular basis pursuant to Exhibit 1, and the readings shall be the basis for preparing Frontier's invoices pursuant to Section 7.
 
(ii) If the level of inaccuracy exceeds 0.5 percent, the readings affected by that component shall be corrected by the amount of the inaccuracy for the period which is definitely known to have been affected by the inaccuracy. If the period is not definitely known and is not mutually agreed upon, the correction shall be made for a period one-half of the time elapsed between the previous calibration test and the date the inaccuracy is corrected. Adjustments to previously issued incorrect invoices shall be made promptly by Frontier.
 
(iii) The Parties may, by mutual consent, establish special procedures for a specific problem or accept delivery quantities determined in a manner not described herein. Mutual consent for acceptance of one special procedure- or delivery quantity shall not set aside the provisions of this section, nor imply acceptance by either Party of that or any special procedure at a future time. If the Parties are unable to agree as to the determination of measurement results, either through metering or other manner, the disputed measurements shall be determined by any mutually agreed surveyor.
 
(iv) Should Frontier fail to obtain suitable measurement results from the Meter, the quantities of the Product provided during the period in question shall be calculated by ETCo if ETCo has installed its own check meter and it has been calibrated according to this section within ninety (90) days of the period in question.  If neither Party has obtained suitable measurement results, the quantities of Product for the period in question shall be estimated, using the average of delivered quantities for a period of time agreed upon by the Parties, or by any other mutually agreed means. Where circumstances develop that a check meter is required on Frontier's assets, and after a reasonable interval of ninety (90) days Frontier has not installed a check meter, ETCo has the right to install a check meter at ETCo expense on Frontier's assets. If ETCo installs a check meter, Frontier shall have the right to have its representative at any calibration test of the check meter. If ETCo installs a check meter, ETCo shall perform all maintenance and calibration tests of the check meter at its own expense and shall furnish Frontier with all readings obtained from the check meter. All testing and calibration requirements for Meters shall apply to check meters.
 
(v) The Parties acknowledge that Meters shall initially not be in place with respect to certain Products. Interim Product measurement arrangements developed by administrative procedures established by the Parties shall be utilized.
 
(vi) At the request of either Party, the Parties shall appoint a loss control committee for the purpose of monthly review and reconciliation of metering issues and accurate determination of volumes exchanged.
 
(b) Quality Testing.
 
Products purchased shall meet the specifications set forth in the applicable Schedule, and the quality determination shall be made by the test methods mutually agreed by the Parties to be industry standards for each Product. Composite samples, continuous samples, or both will be reported by Frontier with respect to each Product at mutually agreed locations.


10.     TRANSFER OF TITLE AND RISK OF LOSS.
 
Title to and risk of loss of all Products delivered by Frontier to ETCo shall pass upon receipt of the Product at the custody transfer point for such Product.
 
11.     CUSTODY TRANSFER
 
Custody transfer points for Frontier delivery and ETCo purchase shall be as designated in Exhibit 2.
 
12.     GASOLINE ADDITIVE SYSTEM
 
(a) Frontier shall provide to ETCo base gasoline without deposit control additives. Frontier shall terminal and throughput the base gasoline as directed by ETCo. Frontier warrants that the base gasoline provided to ETCo for throughputting shall be certified pursuant to 40 CFR Part 80 and all state and local statutes, regulations, and rules pertaining to additive injection (Additive Regulations) for use with both ETCo's proprietary additive and Frontier's generic additive. Frontier and ETCo shall comply with all the obligations imposed on them by Additive Regulations, including the provision of complete Product transfer documentation.
 
(b) ETCo will procure and supply an EPA certified deposit control additive to be injected, at the El Dorado loading rack, into all branded gasoline to be received by ETCo or its designees. ETCo will give Frontier the minimum injection rates for proprietary additive. Frontier is solely responsible for ensuring the proprietary certified deposit control additive is injected at a minimum of the certified injection rate for each Volumetric Additive Reconciliation period as per 40 CFR Part 80.
 
(c) Frontier will procure and supply an EPA certified deposit control additive to be injected by Frontier at the El Dorado loading rack into all unbranded gasoline to be received by ETCo or its designee. Frontier is solely responsible for ensuring the generic certified deposit control additive is injected at a minimum of the certified injection rate for each Volumetric Additive Reconciliation period. Frontier will invoice ETCo or its designee for additive injected into the gasoline.
 
(d) Frontier shall, on a daily basis (excluding weekends and holidays) reconcile gasoline throughput, additive injection levels, and monitor the operation of ETCo's proprietary additive system. Frontier shall immediately notify ETCo if any reconciliation indicates an out of tolerance addition rate and, in that event, shall prevent any further product loading for ETCo until the problem has been resolved. Frontier shall submit a written weekly report to ETCo that contains the daily reconciliation reports for each additive injection meter. This inventory shall be based on a weekly physical inspection in addition to a calculated reconciliation.

(e)Additive Terms & Conditions: ETCo shall install and retain ownership of the ETCo proprietary additive injection system on land provided by Frontier. ETCo shall provide maintenance and calibration of the ETCo proprietary additive system. Frontier shall provide maintenance and calibration of the generic additive injection system. The systems shall include, at a minimum, the following quality assurance measures:

(ii) Additive meters with each injector for use in daily reconciliation.
 
      (f) ETCo agrees that, upon termination of the Agreement, and written request from Frontier, ETCo shall, within sixty (60) days, remove the ETCo proprietary additive system in accordance with Frontier instructions, unless a transfer of ownership is negotiated.
 
(g) Frontier shall inspect the proprietary and generic systems and shall immediately report any malfunctions to ETCo. Frontier will provide initial notice by telephone and follow with notice in writing within forty-eight (48) hours. Frontier will immediately shut down the malfunctioning system and prevent loading of ETCo gasoline until the malfunctioning system has been repaired, unless the Parties agree to an alternative.
 
(h) ETCo and Frontier shall be responsible for complying with the reconciliation record keeping and reporting obligations as imposed by 40 CFR Part 80. In addition, Frontier agrees to provide a copy of all reports sent to any local, state, or federal regulatory agencies or governing bodies regarding ETCo's additive, gasoline, or equipment.
(i)  Frontier shall issue a bill of lading to each ETCo designated transport truck driver stating that the gasoline loaded has been additized, unless Frontier determines in good faith that the gasoline does not comply with Additive Regulations. In this case, Frontier will prevent the gasoline from leaving the Facility, unless the Parties agree to an alternative.
 
(j)  If there are any alleged violations of Additive Regulations agoinst either Party, the other Party will reasonably cooperate in the investigation and defense of the allegations.
 
13.     EXCUSES FOR NON PERFORMANCE.
 
(a) To the extent a Party is rendered wholly or partially unable to perform any of its obligations under this Agreement because of a Force Majeure Event (as defined below in section 13(b)), that Party shall be excused from performance, provided that:
 
(i) promptly after the occurrence of the inability to perform due to a Force Majeure Event, the non-performing Party provides written notice to the other Party of the particulars of the occurrence, including an estimate of its expected duration and probable impact on the performance of its obligations, and continues to furnish timely, regular reports during the period of non-performance;
 
(ii) the non-performing Party shall exercise all reasonable efforts to continue to perform its obligations and shall thereafter continue with reasonable due diligence and good faith to remedy its inability to perform except that nothing in this Agreement, whether contained in Section 13(b) or elsewhere, shall obligate either Party to settle a strike or other labor dispute when it does not wish to do so and except that no Party shall be obligated to cure any Force Majeure Event if the Party reasonably anticipates that it would be unable to cure the Force Majeure Event prior to the date an obligation to sell or to purchase a Product pursuant to any Schedule would terminate;
 
(iii) the suspension of performance shall be of no greater scope and no longer duration than is reasonably necessitated by the Force Majeure Event;
 
(iv) the non-performing Party shall provide the other Party with prompt notice of the cessation of the Force Majeure Event; and
 
(v) no obligation of payment by either Party that arose prior to the occurrence of the Force Majeure Event shall be excused as a result of that occurrence.
 
(b) Force Majeure Event shall mean the following:
 
(i) acts of war, whether declared or not;
 
(ii) insurrection, rebellion, sabotage, acts of terrorists, public disorders, riots, or violent demonstrations;

(v) future order of general applicability of any government, court, or regulatory body claiming jurisdiction arising out of any statute or other regulatory scheme (including, but not limited to, those relating to environmental; ecology; energy; occupational safety; packaging, sale, use, or application; consumer protection; or transportation matters), compliance with which shall, in the judgment of the providing Party, render the performance of an obligation hereunder economically, technically, or commercially infeasible, subject to the exception stated in Section 13(a) above;
 
(vi) inability to lawfully provide a Product or service because of the failure of a governmental agency having jurisdiction over the provision of that Product or service to issue or renew a permit or certificate required where the permit or certificate has been timely and completely applied for and the applying Party has taken reasonable steps to obtain the issuance or renewal of the permit or certificate (including steps to secure interim authority to provide the utility or service while the application is pending), and the permit or certificate is not being withheld due to the culpable conduct of the applying Party;
 
(vii) strikes or labor disputes; or
 
(viii) any other circumstance, whether or not similar to those stated above, which is beyond the reasonable control of the non-performing Party. Notwithstanding the provisions of this section, a Party's inability to perform this Agreement as a result of adverse financial circumstances shall not be considered a Force Majeure Event.
 
(c) Subject to Section 13(a)(ii), if within a reasonable time after a Force Majeure Event has caused the non-performing Party to suspend or delay performance of an obligation, the non-performing Party has failed to take action as that Party could lawfully and reasonably initiate to remove or relieve either the Force Majeure Event or its direct or indirect effects, the other Party may request that it be permitted to provide assistance in removing or relieving a Force Majeure Event or its direct or indirect effects. All assistance or relieving costs will be paid by the non-performing Party. The Parties acknowledge that relieving and repairing the effects of an event shall be a matter of urgency, and each Party agrees to consider in good faith requests by the other Party to provide assistance in that circumstance.
 
(d) The Parties agree to consult each other in good faith to develop administrative procedures for the coordinated response to Force Majeure Events and planning related thereto. Should Frontier terminate this Agreement or reduce the quantity of Product purchased for any reason, including a Force Majeure Event, Frontier shall provide access to Frontier facilities for ETCo to ship the volume of Products which Frontier has committed to deliver until alternative arrangements are in place.

FIRST AMENDMENT
FRONTIER PRODUCTS OFFTAKE AGREEMENT
EL DORADO REFINERY
 
This First Amendment, Frontier Products Offiake Agreement, El Dorado Refinery ("First Amendment") by and between Frontier Oil and Refining Company, a Delaware corporation ("FORC") and Eqiva Trading Company, a Delaware general partnership ("ETCo") is hereby made and entered into this 18th of September 2000. FORC and ETCo are sometimes referred to herein individually as a Party and collectively as the Parties.
 
WITNESSETH:
 
WHEREAS, the Parties entered into the Frontier Products Offtake Agreement, El Dorado Refinery dated as of October 19, 1999 (hereinafter referred to as "the Agreement") and desire to amend certain provisions of the Agreement; and
 
WHEREAS, the Parties recognize that equal weekly deliveries within a month period covered by a Monthly Product Forecast ("MPF") as stated in Section 4. (e) of the Agreement is often not possible due to pipeline schedules and market demand variability; and
 
WHEREAS, the Parties believe that making a monthly adjustment to the one week pricing periods as provided in Schedules B, C, and D attached to the Agreement will mitigate the effect of deliveries which are not made on an equal weekly basis within a month covered by a MPF; and
 
WHEREAS, the Parties recognize that the most desirable pricing method is to utilize an average of the market prices over a month period concurrent with the delivery of the products (i.e. current month average pricing) and desire to change the pricing method in the Agreement; and
 
WHEREAS, the Parties understand that converting to current month average pricing at this time is not equitable to FORC because of the market price structure that has benefited ETCo since the effective date of the original agreement; and
 
WHEREAS, the Parties are willing to utilize a month average adjustment which lags the deliveries until the Parties can agree to convert to current month average pricing; and
 
WHEREAS, the Parties desire to make this First Amendment effective beginning with the product delivered in August 2000; and
 
NOW, THEREFORE, in consideration of the mutual promises and covenants set forth below the Parties agree to amend the Agreement and covenant as follows:
 
1.    PROVISIONAL PRICING.
 
(a)  
The product pricing provisions in Schedules B, C, and D of the Agreement will be used as the weekly provisional prices.
 
(b)  
FORC will continue to invoice ETCo and ETCo will continue to make payments to FORC as provided in Section 7 of the Agreement utilizing the weekly provisional prices.

2.    MONTHLY PRICE ADJUSTMENT.
 
(a)  
On the fifth working day of the month following the delivery month FORC will calculate the monthly price adjustment and transmit an invoice or credit memo to ETCo.
 
(b)  
Payment will be made by the owing Party, by electronic funds transfer, within two Business Days of receipt of the invoice to an account at a bank nominated by the receiving Party.
 
(c)  
The average monthly price for each product is calculated by weighting the provisional price for each delivery period on a percentage basis as the provisional price applies to the days in each delivery month.
 
 (i) For example the weighting given to each price period to calculate an averagemonthly price for a product delivered in August of 2000 is as follows:
(1) 22.58% or 7/31 of the July 24 through July 28 price period,
(2) 22.58% or 7/31 of the July 31 through August 4 price period,
(3) 22.58% or 7/31 of the August 7 through August 11 price period,
(4) 22.58% or 7/31 of the August 14 through August 18 price period, and
(5) 9.68% or 3/31 of the August 21 through August 25 price period.
 
 (ii) The average monthly price for each product in August is calculated by applying the weighting as shown in 2.(c)(i) in Attachment A.
 
 (iii) As a further example the weighting given to each price period to calculate an average monthly price for a product delivered in September of 2000 is as follows:
(1) 13.33% or 4/30 of the August 21 through August 25 price period,
(2) 23.33% or 7/30 of the August 28 through September 1 price period,
(3) 23.33% or 7/30 of the September 4 through September 8 price period,
(4) 23.33% or 7/30 of the September 11 through September 15 price period, and
(5) 16.68% or 5/30 of the September 18 through September 22 price period.
 
(d)
The weighting given to each price period to calculate an average monthly price for a product delivered in each month subsequent to September 2000 will follow the conventions exemplified in paragraphs c(i) and c(iii) above.
 
(e)
The monthly product price adjustment is the difference between the price invoiced using the provisional pricing and the average monthly price for an individual product.
 
(f)
The monthly price adjustment is the sum of the monthly product price adjustments.
 
(g)
If the monthly price adjustment for August 2000 is in the favor of ETCo, the adjustment is limited to $500,000.

3.    EFFECTIVE DATE
 
This First Amendment to product pricing set forth in Schedules B, C, and D of the Agreement, which changes the method of calculating prices, will be effective beginning with the product delivered in August 2000 and compliance with the terms and conditions of this First Amendment shall be effective on the date of execution by the Parties; provided, however, compliance with 2(a) above by FORC shall be extended by two (2) business days after execution by both parties.
 
Except as explicitly stated herein, no other provisions of the Agreement are affected by the First Amendment and they remain in full force and effect.
 
In witness whereof, the Parties have below affixed the signature of their authorized representatives, who warrant that they are legally empowered to bind the Party on whose behalf they have signed.

(b) Payment will be made by the owing Party to an account at a bank nominated by the receiving Party, by electronic funds transfer, within two Business Days of receipt of the invoice.
 
(c) The average monthly price for Avjet is calculated by weighting the provisional price for each delivery period on a percentage basis as the provisional price applies to the days in each delivery month.
 
(i) For example the weighting given to each price period to calculate an average monthly price for the product delivered in August of 2000 is as follows:
(1)          22.58% or 7/31 of the July 24 through July 28 price period,
