Supersedes November 1983 General Provisions

G.             Financial Responsibility:  Notwithstanding anything to the contrary in this Agreement, should Seller reasonably believe it necessary to assure payment, Seller may at anytime require, by written notice to Buyer, advance cash payment or satisfactory security in the form of a Letter or Letters of Credit at Buyer’s expense in a form and from a bank acceptable to Seller to cover any or all deliveries of crude oil.  If Buyer does not provide the Letter of Credit on or before the date specified in Seller’s notice under this section, Seller or Buyer may terminate this Agreement forthwith.  However, if a Letter of Credit is required under the Special Provisions of this Agreement and Buyer does not provide same, then Seller only may terminate this Agreement forthwith.  In no event shall Seller be obligated to schedule or complete delivery of the crude oil until said Letter of Credit is found acceptable to Seller.  Each party may offset any payments or deliveries due to the other party under this or any other agreement between the parties.

If a party to this Agreement (the “Defaulting Party”) should (1) become the subject of bankruptcy or other insolvency proceedings, or proceedings for the appointment of a receiver, trustee, or similar official, (2) become generally unable to pay its debts as they become due, or (3) make a general assignment for the benefit of creditors, the other party to this Agreement may withhold shipments without notice.

H.            Liquidation:

(1)           Right to Liquidate.  At any time after the occurrence of one or more of the events described in the third paragraph of Section G, Financial Responsibility, the other party to the Agreement (the “Liquidating Party”) shall have the right at its sole discretion, to liquidate this Agreement by terminating this Agreement.  Upon termination, the parties shall have no further rights or obligation with respect to this Agreement, except for the payment of the amount(s) (the “Settlement Amount” or “Settlement Amounts”) determined as provided in Paragraph (3) of this section.

(2)           Multiple Deliveries.  If this Agreement provides for multiple deliveries of one or more types of crude oil in the same or different delivery months, or for the purchase or exchange of crude oil by the parties, all deliveries under this Agreement to the same party at the same delivery location during a particular delivery months hall be considered a single commodity transaction (“Commodity Transaction”) for the purpose of determining the Settlement Amount(s).  If the Liquidating Party elects to liquidate this Agreement, the Liquidating Party must terminate all Commodity Transactions under this Agreement.

(3)           Settlement Amount.  With respect to each terminated Commodity Transaction, the Settlement Amount shall be equal to the contract quantity of crude oil, multiplied by the difference between the contract price per barrel specified in this Agreement (the “Contract Price”) and the market price per barrel of crude oil on the date the Liquidating Party terminates this Agreement (the “Market Price”).  If the Market Price exceeds the Contract Price in a Commodity Transaction, the selling party shall pay the Settlement Amount to the buying party.  If the Market Price is less than the Contract Price in a Commodity Transaction, the buying party shall pay the Settlement Amount to the selling party.  If the Market Price is equal to the Contract Price in a Commodity Transaction, no Settlement Amount shall be due.

(4)           Termination Date.  For the purpose of determining the Settlement Amount, the date on which the Liquidating Party terminates this Agreement shall be deemed to be (a) the date on which the Liquidating Party sends written notice of termination to the Defaulting Party, if such notice of termination is sent by telex or facsimile transaction; or (b) the date on which the Defaulting Party receives written notice of termination from the Liquidating Party, if such notice of termination is given by United States mail or a private mail delivery service.

(5)            Market Price.  Unless otherwise provided in this Agreement, the Market Price of crude oil sold or exchanged under this Agreement shall be the price for crude oil for the delivery month specified in this Agreement and at the delivery location that corresponds to the delivery location specified in this Agreement, as reported in Platt’s Olgram Price Report (“Platt’s”) for the date on which the Liquidating Party terminates this Agreement.  If Platt’s reports a range of prices for crude oil on that date, the Market Price shall be the arithmetic average of the high and low prices reported by Platt’s.  If Platt’s does not report prices for the crude oil being sold under this Agreement, the Liquidating Party shall determine the Market Price of such crude oil in a commercially reasonable manner, unless otherwise provided in this Agreement.

(6)           Payment of Settlement Amount.  Any Settlement Amount due upon termination of this Agreement shall be paid in immediately available funds within two business days after the Liquidating Party terminates this Agreement.  However, if this Agreement provides for more than one Commodity Transaction, or if Settlement Amounts are due under other agreements terminated by the Liquidating Party, the Settlement Amounts due to each party for such Commodity Transactions and/or agreements shall be aggregated.  The party owing the net amount after such aggregation shall pay such net amount to the other party in immediately available funds within two business days after the date on which the Liquidating Party terminates this Agreement.

(7)            Miscellaneous.  This section shall not limit the rights and remedies available to the Liquidating Party by law or under other provisions of this Agreement.  The parties hereby acknowledge that this Agreement constitutes a forward contract for purposes of Section 556 of the U.S. Bankruptcy Code.

I.              Equal Daily Deliveries:  For price purposes only, unless otherwise specified in the Special Provision, all crude oil delivered hereunder during any calendar month shall be considered to have been delivered in equal daily quantities during such month.

J.              Exchange Balancing:  If volumes are exchanged, each party shall be responsible for maintaining the exchange in balance on a month-to-month basis, as near as pipeline or other transportation conditions will permit.  In all events upon termination of this Agreement and after all monetary obligations under this Agreement have been satisfied, any volume imbalance existing at the conclusion of this Agreement of less than 1,000 or more, limited to the total contract volume, will be settled by the underdelivering party making delivery of the total volume imbalance in accordance to the delivery provisions of this Agreement applicable to the underdelivering party, unless mutually agreed to the contrary.  The request to schedule all volume imbalances must be confirmed in writing by one party or both parties. Volume imbalances confirmed by the 20th of the month shall be delivered during the calendar month after the volume imbalance is confirmed.  Volume imbalances confirmed after the 20th of the month shall be delivered during the second calendar month after the volume imbalance is confirmed.

Effective January 1, 1993

Supersedes November 1983 General Provisions.

K.            Delivery, Title, and Risk of Loss:  Delivery, title, and risk of loss of the crude oil delivered hereunder shall pass from Seller to Buyer as follows:

For lease delivery locations, delivery of the crude oil to the Buyer shall be effected as the crude oil passes the last permanent delivery range and/or meter connecting the Seller’s lease/unit storage tanks or processing facilities to the Buyer’s carrier.  Title to and risk of loss of the crude oil shall pass from Seller to Buyer at the point of delivery.

For delivery locations other than lease/unit delivery locations, delivery of the crude oil to the buyer shall be effected as the crude oil passes the last permanent delivery range and/or meter connecting the delivery facility designated by the Seller to the Buyer’s carrier.  If delivery is by in-line transfer, delivery of the crude oil to the Buyer shall be effected at the particular pipeline facility designated in this Agreement.  Title to and risk of loss of the crude oil shall pass from Seller to the Buyer upon delivery.
