PURCHASE AND SALE



2.1 Purchase and Sale. Buyer hereby agrees to purchase and receive and Sellers hereby agree to sell and deliver all of the Crude Oil produced and owned by Sellers from Covered Properties; provided however, that the foregoing
Sellers agreement shall be subject to any Existing Contract. No Crude Oil shall be sold hereunder in contravention of an Existing Contract by such Seller or from such properties until the Existing Contract has expired or been terminated.
Currently, the Covered Properties are set forth on Exhibit A attached hereto and incorporated herein. Exhibit A shall be promptly updated to add or delete Covered Properties.



2.2 Addition of Sellers. Except for the Nuevo Excluded Properties, if
a Person who owns Crude Oil producing properties within the Marketing Area becomes an Affiliate of PXP, PXP shall give prompt notice of such acquisition to Buyer, and shall cause such Affiliate to become a Seller hereunder by executing and
delivering a ratification of this Agreement to Buyer as soon as practicable after the date such Person became an Affiliate of PXP.

---

2.3 Addition of Covered Properties. Except for the Nuevo Excluded Properties, each Seller shall
give prompt notice to Buyer of such Sellers acquisition of any Crude Oil producing properties and if a Seller acquires additional Crude Oil producing properties (or with respect to the Crude Oil producing properties owned by a newly added
Seller pursuant to Section 2.2), Buyer shall have the opportunity to match the Competitive Price. If Buyer agrees to match or pay a price higher than the Competitive Price within 15 business days of receipt of notice from such Seller pursuant to
Section 2.2 or this Section 2.3 (for this purpose, the price paid by Buyer shall be inclusive of the Marketing and Administrative Fee), such properties shall become Covered Properties hereunder; provided, however, that such Sellers obligation
to deliver and sell Crude Oil from such properties shall be subject to the provisions of Section 2.1 with respect to any Existing Contract. The Parties shall execute an additional agreement (similar in form to the PXP Gulf Coast Agreement attached
hereto as Exhibit C) evidencing the price to be paid for the Crude Oil ftom such properties and the term for which such price is applicable. Upon expiration of such term, the price may be renegotiated to reflect changes in market value of
such Crude Oil production. Seller shall promptly submit a revised Exhibit A to reflect the addition of any Covered Properties added under this Section 2.3. If Buyer does not submit an offer or if the offer does not match or exceed the
Competitive Price, such properties shall not (absent subsequent agreement of Buyer and such Seller) become Covered Properties and shall be released from any dedication of production under this Agreement.



2.4 Release of Covered Properties or Sellers



(a) If a Seller, other than PXP, ceases to be an Affiliate of PXP, this
Agreement shall terminate with respect to such Seller, its properties, and the Crude Oil produced therefrom, with such termination to be effective as soon as practicable following the date such Seller gives written notice to Buyer that it has ceased
to be an Affiliate of PXP; but in no event shall such properties cease to be subject to this Agreement prior to the termination of and to the extent of any agreement Buyer has previously entered into for the sale of Crude Oil attributable to
production from such properties (including, without limitation, the agreement referenced in the Tosco Letter).



(b) If a Seller sells, transfers or otherwise disposes of any of its properties or the interests therein which are within the Marketing Area, such
properties or interests shall cease to be subject to this Agreement as soon as practicable following the date of such sale, transfer or disposition; but in no event shall such properties or interests cease to be subject to this Agreement prior to
the termination of any agreement Buyer has previously entered into for the sale of Crude Oil attributable to production from such properties or interests (including, without limitation, the agreement referenced in the Tosco Letter).



(c) If a Seller and Buyer determine that it is impracticable for Buyer to
continue to purchase Crude Oil from any Covered Property, such Seller and Buyer may, by mutual written agreement, terminate this Agreement with respect to such property. Thereafter, neither such Seller nor Buyer shall have any further obligations
under this Agreement with respect to such property.



2.5
Further Documentation. Upon request by any Party affected by an addition or release pursuant to Sections 2.2 through 2.4 above, all Parties hereto shall execute and deliver to the requesting Party such documents and instruments as may be
reasonably necessary to evidence additions or releases of Parties or properties to this Agreement.



7



---

2.6 Delivery. Delivery shall be made from the lease tankage on the properties, or such other point
as is mutually agreed to and reflected on Exhibit A (a Delivery Point), into transportation facilities designated by Buyer.



2.7 Price. The price to be paid by Buyer for Crude Oil sold hereunder (the Purchase Price) shall be equal to the Sales Price for
each Barrel as determined in this Section 2.7, less the sum of (i) a marketing and administrative fee of $.20 for each Barrel sold (the Marketing and Administrative Fee) and (ii) with respect to Crude Oil which is not sold
by Buyer at a Delivery Point, the reasonable out -of-pocket expenses (if any) incurred by Buyer to transport or exchange each Barrel of such Crude Oil; provided, however, that the Marketing and Administrative fee shall not apply to third-party
royalty barrels; and provided, further, that Buyer may elect to reduce or eliminate the Marketing and Administrative Fee with respect to and in connection with making an offer under Section 2.3. Buyer hereby agrees to use commercially reasonable
efforts to obtain (i) the highest Sales Price for Crude Oil sold pursuant to this Agreement and (ii) the lowest out-of-pocket expenses incurred by Buyer to transport or exchange each Barrel of Crude Oil, in each case taking into account all
circumstances surrounding the transportation and sale of the Crude Oil. Buyer will, upon request of Seller, provide information with respect to bids solicited by Buyer for the sale of Crude Oil. Buyer also agrees that it will give Sellers notice
prior to entering into any contract with third parties re the Crude Oil sold pursuant to this Agreement. Sellers will promptly, upon such notice, either approve or disapprove such contract, in writing. Buyer will not sell any Crude Oil under such
contract without written approval from the relevant Sellers.



The Sales Price shall be determined according to the following:



(a) For Crude Oil that Buyer resells at a Delivery Point, the Sales Price shall be the price received by Buyer for each Barrel sold at the Delivery Point.



(b) For Crude Oil that Buyer either (i) transports to a location other than a Delivery Point (a Trade
Location) or (ii) exchanges for other Crude Oil at a Trade Location, the Sales Price shall be determined as follows:



(x) if such Crude Oil is not aggregated with other Crude Oil owned by Buyer, the Sales Price shall be equal to the price received by Buyer for each Barrel
sold at the Trade Location; or



(y) if such Crude Oil is
aggregated with other Crude Oil owned by Buyer, the Sales Price shall be equal to the sum of (i) the posted price received by Buyer for each Barrel sold at the Trade Location and (ii) a premium equal to the Platts P+ Average and plus or minus,
as applicable, the Platts Difference at the Trade Location. If the Platts P+ Average or the Platts Difference is not published, then the price shall be the weighted average for each Barrel of Buyers sales at such Trade
Location;



8



---

(c) with respect to the properties acquired by PXP in the 3TEC transaction, the Sales Price shall be the
price set forth in the PXP Gulf Coast Agreement and any amendment thereto to reflect changes in the market value of the Crude Oil produced from such properties; or



(d) for Crude Oil produced from Covered Properties added pursuant to Section 2.3, the Sales Price shall be the price, net of
the Marketing and Administrative Fee, offered by Buyer in connection with such addition.



2.8 Payment. Payments by Buyer for Crude Oil purchased hereunder shall be based on the applicable Purchase Price, the volumes delivered by Sellers, and 100% of the interest shown on Exhibit A attached
hereto, less state taxes which are withheld by Buyer. All payments shall be wired to PXP for the account of the Sellers in accordance with written instructions from PXP. Such wire transfers shall be made on the twentieth day of the month following
the month of actual receipt of Crude Oil; provided that, if the twentieth day of the month falls on a Sunday or a banking holiday, payment will be made on the following Business Day, or if the twentieth day of the month falls on a Saturday, payment
will be made on the preceding Business Day.



2.9 General
Provisions. Plains Marketing, L.P.s General Provisions dated November 1, 1998 (the General Provisions), are attached hereto as Exhibit D and are incorporated by reference and made a part of this Agreement. If any conflict
should arise between the General Provisions and the information stated herein, this Agreement shall apply.



2.10 No Restrictions. No provision contained in this Agreement shall in any way be interpreted as being a restriction on the ability of any Seller
to conveyor transfer Crude Oil to any other Seller, or to any of their subsidiaries. However, all such Crude Oil conveyed or transferred to a Seller or subsidiary is and shall remain subject to this Agreement including the obligations contained in
this Article 2.



ARTICLE 3

RENEGOTIATION



Prior to November 23, 2004 and November 23, 2007 (the Renegotiation Date(s)), either the Sellers or Buyer may request, in writing, to
renegotiate the Marketing and Administrative Fee. Any such renegotiation request must be accompanied with documentation supporting the request to either increase or decrease the Marketing and Administrative Fee, and shall be in accordance with the
following procedures:



(a) At least 120 days prior to the
applicable Renegotiation Date, either the Sellers or Buyer may request, in writing, to renegotiate the Marketing and Administrative Fee. If neither Sellers nor Buyer makes such a request, the Parties will be deemed to have agreed upon the
then-existing Marketing and Administrative Fee.



9



---

(b) Sellers and Buyer shall renegotiate the Marketing and Administrative Fee in good faith. If a revised
Marketing and Administrative Fee has not been agreed upon at least 75 days prior to the applicable Renegotiation Date, then Sellers may enter into negotiations for the sale of their Crude Oil with any Person who is not an Affiliate of Sellers. If
Sellers do not reach an agreement with such non-affiliated Person at least 30 days prior to the applicable Renegotiation Date, then this Agreement shall continue and the Marketing and Administrative Fee shall be revised, effective the first day
after the applicable Renegotiation Date, to equal the Marketing and Administrative Fee last offered by Buyer.



(c) If Sellers are successful in reaching agreement with such non-affiliated Person which provides for (i) a term of not less than one year nor more than
three years, (ii) and a Marketing and Administrative Fee which is less than the Marketing and Administrative Fee last offered by Buyer, this Agreement shall terminate. Such termination shall be effective on the applicable Renegotiation Date and,
thereafter, Sellers may sell their Crude Oil to such non-affiliated Person during the term of their agreement with such Person. Within 120 days prior to the end of the term of such other agreement, either the Sellers or Buyer may request
negotiations to resume this Agreement and to negotiate a revised Marketing and Administrative Fee in accordance with the procedures set forth above.



(d) Sellers and Buyers right to request a renegotiation of the Marketing and Administrative Fee in order to resume this Agreement shall
continue until such time that this Agreement terminates pursuant to Article 5.



If the parties agree to a Marketing and Administrative Fee pursuant to clause (b) above (or are deemed to have agreed pursuant to clause (a) above), the term of this Agreement shall be extended for three years from
the November 23, 2004 Renegotiation Date or until November 23, 2007, or for two years in the case of the November 2007 Renegotiation Date, or until November 23, 2009, unless earlier terminated as provided herein.



ARTICLE 4

SELLERS INDEMNITY

(collectively, the Claims), including claims due to personal injury, death, or loss or damage of property, whether or not caused by the sole, joint and/or concurrent negligence, fault or strict liability of any member of the Buyer
