The procedure for entering into a Transaction between Seller and Purchaser is as follows:

(i) In consultation with Purchaser concerning Purchaser’s then-existing need for Crude Oil, Seller shall submit bids to, or enter into negotiations with, Approved Suppliers having available supplies of Crude Oil in or around either (1) an Approved Injection Point or (2) any other Injection Point that is mutually acceptable to Seller and Purchaser, for the purchase by Seller of certain quantities of Crude Oil that are consistent with Purchaser’s needs.

If Seller does not accept such quote/bid within the time period described in the foregoing sentence, Seller’s silence or failure to respond shall be deemed a rejection. If Seller accepts such quote/bid, Seller shall promptly cause to be confirmed the essential terms of Seller’s purchase transaction with the Supplier, including:

(B) the type of Crude Oil to be acquired,

(C) the price or pricing formula to be used by Seller to calculate payments to Supplier for all Crude Oil sold to Seller,

Each Supply Contract shall be acceptable as to both form and substance to both Seller and Purchaser and shall contain terms, provisions and conditions generally used for the sale of Crude Oil in and around the applicable Injection Point. Seller’s acceptance of a quote/bid with a Supplier shall also authorize Seller to enter into one or more Initial Swaps as contemplated by Section 2.01(f).

The parties agree that such agreement may occur through an exchange of facsimile transmissions, electronic messages or orally. Notwithstanding the forgoing, the parties further agree that the obligations of both Purchaser and Seller under such Transaction and the related Deal Sheet shall be subject to and conditioned upon Seller and Supplier actually entering into a Supply Contract that is consistent in all respects with the terms set out in the Deal Sheet.

If Delivery for any Batch is delayed for any reason and as a result thereof, Delivery of such Batch occurs later than the originally scheduled Off-take Month, the parties shall promptly meet to ascertain whether a Replacement Swap should be entered with respect to such Batch.

(a) Each of Seller and Purchaser shall take such actions as shall be necessary to properly nominate, schedule and confirm the delivery and receipt of Crude Oil subject to each Transaction at the relevant Delivery Location in each Delivery Month in compliance with applicable rules and regulations of the transporting Pipeline(s). Without limiting the foregoing, and to the extent the Delivery Location for a Transaction is on the Spearhead Pipeline, Seller shall assign to Purchaser, and Purchaser shall assume and accept, Seller's rights in the Crude Oil transportation tariff applicable to the Spearhead Pipeline and the associated portion of the Enbridge Pipeline that is located in the United States, such rights currently derived from CCPS Transportation, LLC’s (“CCPS”) Xxxxxx Xx. 0 on file with the Federal Energy Regulatory Commission, as supplemented and/or amended from time to time (“Tariff No. 4”). Seller’s assignment and Purchaser's assumption of the foregoing rights shall be limited to the Batches involved in a Transaction and shall be evidenced by certificates acceptable as to form and substance by each of CCPS, Seller and Purchaser.

(b) Purchaser shall use reasonable commercial efforts to cause the transporting Pipelines to transport each Batch of Seller Crude Oil in accordance with all Governmental Requirements and the Pipelines’ operating rules and regulations for delivery during the applicable Off-take Month. In connection with Crude Oil purchased by Seller under the Supply Contracts for resale to Purchaser in the Transactions, Purchaser shall act as Seller’s representative in making all necessary ministerial arrangements with respect to nominating and scheduling deliveries, managing overall imbalance and cash-out exposure, trade imbalances with other shippers on each Pipeline’s system, and cash-out imbalances with transporters, including, taking actions to avoid or mitigate pipeline and distribution system penalties associated with transportation, distribution and delivery of Seller Crude Oil, including monitoring for system alert or operational notices, communicating with the Pipelines regarding operational matters that may affect imbalances or penalties, and taking actions to comply with or respond to any of the foregoing and handling any issues related thereto, and, in the event transportation of Seller Crude Oil is interrupted or suspended by a transporting Pipeline, assisting in arranging for storage of such Crude Oil on such terms and conditions as Seller deems acceptable (all of the foregoing being referred to as the “Transportation Activities”). Notwithstanding anything to the contrary in Section 2.03, Section 5.02 or Section 5.03, if Purchaser fails to diligently and timely undertake any Transportation Activities described in this Section 2.03(b), then, as its sole and exclusive remedy for such failure, Seller shall have the right to take control of and make (whether directly or through a service provider) any such Transportation Activities, and all direct costs incurred by Seller shall be charged to Purchaser as an additional Carrying Cost. For the avoidance of doubt, nothing in this Section 2.03(b) shall confer to Purchaser the right to enter into or execute any contracts on behalf of Seller.

(c) Purchaser shall have the obligation to (i) procure that all Seller Crude Oil purchased by Seller for resale to Purchaser is stored or transported in such manner as will ensure that, to the extent consistent with prudent business storage practices in respect of various grades of Crude Oil, that Crude Oil purchased under a Supply Contract is separated physically from, and is not commingled with, any and all other Crude Oil or any other grade (provided, however, Seller acknowledges that Seller Crude Oil will be transported from the Injection Points set forth in the Supply Contracts to the Delivery Locations set forth in the Deal Sheets through the common carrier facilities of the Pipelines and pursuant to such Pipelines’ respective rules, regulations and standard practices affecting the transportation and/or storage of crude oil and other petroleum substances), and (ii) take commercially reasonable steps to assure the proper measurement of Seller Crude Oil, including verification that the quality or grade designated for purchase in a Supply Contract and delivered to a Pipeline is within commercial tolerances for such quality or grade and conforms to the latest American Society for Testing Materials (“ASTM”) or American Society of Mechanical Engineers-American Petroleum Institute (“API”) (Petroleum PD Meter Code) published methods then in effect and applicable to such quality or grade, handling the rejection of non-conforming Crude Oil, and pursing any claims of loss or damage arising therefrom.

(d) Prior to the delivery of Crude Oil to Purchaser at a Delivery Location in accordance with a Deal Sheet, Purchaser shall not claim or hold itself out as the owner of any Seller Crude Oil and will not create or permit any third party acting by or through Purchaser to create any mortgage, charge, pledge, lien or to otherwise encumber any portion of Seller Crude Oil without Seller’s prior approval in writing. Purchaser shall not deal with or in Seller Crude Oil in any way or otherwise part with possession of Seller Crude Oil without Seller’s prior written consent, except as expressly contemplated hereby, the Deal Sheets and/or the Supply Contracts, and Purchaser shall procure that none of its agents or any operators of any Pipeline do so. If a Pipeline operator shall issue to Purchaser (in its capacity as Seller’s representative with respect to the Transportation Activities) any certificates or documents evidencing ownership of the Seller Crude Oil prior to the Delivery Location, Purchaser agrees that such certificates or documents shall be issued in the name of Seller, or in the name of Purchaser on behalf of Seller, and that each original receipt will be sent as soon as practicable after its issue to Seller.

(e) To the extent any Pipeline operator or common carrier requires Seller to purchase or otherwise pay for a quantity of Crude Oil to serve as “tank-bottoms” or “retention stock” (collectively, “Retention Stock”), Purchaser agrees to promptly acquire and deliver such quantity of Crude Oil as Retention Stock, or to pay for such Retention Stock at the price invoiced to Seller. Upon termination of this Agreement and upon Purchaser’s payment in full of all amounts due to Seller under this Agreement, Seller shall convey to Purchaser all its right, title and interest in and to such Retention Stock.

Section 2.04 Transportation Fees and Documentation

(a) In consideration for Seller’s sale of Crude Oil to Purchaser hereunder, Purchaser agrees to pay all tariffs, costs and expenses charged by the Pipelines for the transportation of each Batch of Crude Oil acquired by Seller pursuant to a Deal Sheet from such Crude Oil’s Injection Point to its Delivery Point. Seller shall cause to be provided to Purchaser each month a statement setting forth the transportation-related charges actually incurred by Seller (in its capacity as shipper) together with supporting pipeline invoices, statements and/or delivery schedules. Purchaser shall pay to Seller (or at Seller’s request, the Pipelines) all amounts due pursuant to this Section 2.04 no later than the date payments are due and payable to the relevant Pipelines.

(b) Purchaser shall be responsible for (i) the preparation of, delivering and retaining copies of, bills of sale, bills of lading, monthly pipeline reconciliation statements (in substantially the form of Exhibit E attached hereto or such other form as is mutually agreeable), quarterly lists of the grades of Crude Oil then approved for transportation by the Pipelines under approved and effective tariffs applicable or available to the Crude Oil, receipts and other instruments transferring title to Crude Oil subject to the Supply Contracts, the Deal Sheets and any transportation or storage agreement or tariff relating to the foregoing, (ii) arranging for the payment prior to becoming delinquent of all undisputed invoices of Suppliers, Pipelines, Pipeline operators and other parties, and amounts payable under transportation or storage agreements, pipeline agreements and other similar agreements, and (iii) handling accounting disputes and reconciliations, and preparing all necessary sales tax documents for filing by Seller as appropriate at the relevant Delivery Location.

(c) Purchaser shall maintain and make available to Seller any documentation received by Purchaser or in Purchaser’s possession related to the Seller Crude Oil and at any reasonable time, permit any representatives designated by Seller, upon reasonable prior notice, to visit and inspect its records relating to Seller Crude Oil and the contracts and agreements associated therewith, to examine and make extracts from its books and records, and to discuss its affairs, finances and condition with its officers and independent accountants, all at such reasonable times and as often as reasonably requested.

Section 2.05 Payment of Transfer Fees

. Purchaser shall be solely responsible for the payment of all in line transfer fees payable to the owner of the Pipeline facilities, if any, in connection with the delivery of the Crude Oil at the relevant Delivery Location, including any such fees accruing to the account of Seller.

Section 2.06 Force Majeure Default Delivery Location

. If as a result of an event of Force Majeure, either (a) Seller is unable, after using all reasonable commercial efforts, to deliver Crude Oil to Purchaser at the relevant Delivery Location or (b) Purchaser is unable, after using all reasonable commercial efforts, to receive Crude Oil from Seller at the relevant Delivery Location, then, to the extent commercially feasible, Seller shall be obligated to deliver and Purchaser shall be obligated to receive, the affected quantities of Crude Oil at a mutually acceptable comparable delivery location with mutually acceptable adjustments for quality, location and associated transportation costs. If the parties are unable to agree on a mutually acceptable comparable delivery location with mutually acceptable adjustments for quality, location and associated transportation costs, then Section 6.01(c) shall apply to the affected quantities.

Section 2.07 Transportation Imbalances

. Seller and Purchaser shall notify the other as promptly as possible of any changes in its rate of delivery or receipt of Crude Oil at the relevant Injection or Delivery Location, as the case may be, and take all reasonable actions necessary to avoid the incurrence of Pipeline penalties and imbalances. In the event a transporting Pipeline determines that a Transportation Imbalance (whether positive or negative) exists with respect to any Seller Crude Oil transported by such Pipeline during the term of this Agreement, and such Pipeline requires Seller (as shipper) to settle such Transportation Imbalance in cash or in kind, Seller shall assign to Purchaser, and Purchaser shall assume and accept, all rights and obligations with respect to such Transportation Imbalance, including the obligation to make payment for (or if settled in kind, make delivery of) any shortage and the right to receive payment for (or accept delivery of) any overage, in each case as established by the invoices, records and statements of the transporting Pipeline.

Section 2.08 Rights and Remedies; Waiver of Certain Damage Claims

. Except as set forth in this Section 2.08, the rights and remedies of the parties set forth in this Agreement and the other Transaction Documents are non-exclusive of the other rights and remedies of the parties existing at law or equity. It is expressly agreed that, notwithstanding any other rights or remedies which a party may have, payments made in accordance with Section 2.07 or Articles V or VI of this Agreement constitute the exclusive and total compensation for damages available to Seller and Purchaser for non-delivery or non-acceptance of Crude Oil. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, NO PARTY SHALL BE LIABLE FOR ANY PUNITIVE, EXEMPLARY, INCIDENTAL, CONSEQUENTIAL, INDIRECT OR DIRECT (OTHER THAN AS SET FORTH IN THIS SECTION 2.08) OR OTHER DAMAGES, IN TORT, CONTRACT OR OTHERWISE IN RESPECT THEREOF. THE PARTIES ACKNOWLEDGE AND AGREE THAT THE CRUDE OIL SUBJECT OF THIS AGREEMENT IS NOT UNIQUE AND THAT NO CLAIM FOR SPECIFIC PERFORMANCE IS APPROPRIATE OR WILL BE MADE BY ANY PARTY.

Section 2.09 Possession, Title and Risk

. Possession of and title to any quantities of Crude Oil Delivered pursuant to this Agreement and any Deal Sheet shall pass from Seller to Purchaser at the relevant Delivery Location when such Crude Oil is either (a) transferred to or delivered into the facilities of Purchaser’s designee at the Delivery Location for the account of Purchaser and such transfer is recorded by the applicable metering device or (b) the transporting Pipeline issues a custody transfer certificate or similar form or the Pipeline enters a notation in the Pipeline’s electronic records. Until such time, Seller shall be deemed to be in control and possession of, have title to, risk of loss of and be responsible for such Crude Oil and, after such time, Purchaser shall be deemed to be in control and possession of, have title to, risk of loss of and be responsible for such Crude Oil.

Section 2.10 Taxes

(a) Seller is liable for and shall pay, cause to be paid or reimburse Purchaser if Purchaser shall have paid, all Taxes applicable to the Crude Oil sold hereunder prior to the time title to the Crude Oil has passed to Purchaser, unless allocated to Purchaser as hereinafter provided.

Both parties shall use all their reasonable efforts to administer this Agreement and implement its provisions in accordance with their intent to minimize Taxes. Purchaser represents that it is engaged in the refining of the Crude Oil Delivered under this Agreement and the Deal Sheets and Purchaser is purchasing the Crude Oil for refining, and accordingly Purchaser is entitled to purchase the Crude Oil hereunder free of any Taxes pursuant to an Oklahoma manufacturing exemption. Each party agrees to cooperate with obtaining any exemption from or reduction of Tax upon request by the other party.

(b) Each of Seller and Purchaser shall be responsible for and discharge all taxes on its net worth or income, whether assessed or collected by any governmental authority of the United States, Canada, the Republic of Ireland or any political subdivision thereof, and shall indemnify and hold the other party harmless from and against any liabilities relating to such taxes.

With respect to any Batch of Crude Oil, Purchaser shall have the unilateral right and option at any time prior to delivery of such Crude Oil at the Delivery Location then specified in a Deal Sheet to purchase all of such Batch of Crude Oil by giving written notice to Seller of such election as soon as reasonably possible; provided, however, all early purchases pursuant to this Section 2.13 shall be made at a Delivery Location within the United States unless Seller otherwise agrees. Any such early sale of Crude Oil shall be deemed to be a sale of Crude Oil for purposes of Section 2.01 and Purchaser shall make payment for such Crude Oil in accordance with Section 2.01(d). The Purchase Price for such Batch of Crude Oil shall be determined as of the date of actual purchase, with, for this purpose, any Swaps related to the Batch subject of early purchase being settled by Seller as soon as commercially reasonable following Seller’s receipt of Purchaser’s notice of its election. Purchaser shall be authorized to provide all notices to transporting Pipelines concerning each election and early purchase by Purchaser pursuant to this Section 2.13. Upon the giving of Purchaser’s notice, the affected Deal Sheet shall be deemed to have been amended to conform to the terms of Purchaser’s election.

(f) any event or circumstance shall occur and be continuing which could reasonably be expected to have a material and adverse effect on the financial condition or the ability of Guarantor and Purchaser to perform its obligations under this Agreement and the other Transaction Documents.

Section 5.03 Default Rights; Early Termination

. At any time while an Event of Default is continuing, the non-defaulting party may provide a written notice to the defaulting party specifying the relevant Event of Default, and either demand adequate assurances under Article 2-609 of the Uniform Commercial Code (and pending the delivery of such adequate assurances, suspend its own performance, unless such performance is the payment of money) or designate a Business Day not earlier than the fifth (5th) Business Day following the defaulting party’s receipt of such notice (as provided in Section 7.01) as a default termination date (“Default Termination Date”).

Such payment shall be due on the date Purchaser presents to Seller a certificate reflecting the amount due. Purchaser agrees to use all reasonable commercial efforts to minimize the Replacement Value and Purchaser shall prepare and deliver to Seller, within five (5) Business Days after the end of the applicable Off-take Month, a certificate setting out the calculation of the Replacement Value accompanied by reasonably available back-up documentation therefor.
