      2.2  Addition or Release of Properties or Sellers.  Crude Oil producing
properties and Sellers shall be added or released from the terms and provisions
of this Agreement upon the occurrence of the following events:

     (a) If a Person who owns Crude Oil producing properties within the

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 Plains Resources.

     (b) If a Seller acquires additional Crude Oil properties within the
Marketing Area, such additional properties and the Crude Oil owned and produced
therefrom by such Seller shall become subject to this Agreement as soon as
practicable after the date of acquisition of such properties.

     (c) If a Seller, other than Plains Resources, ceases to be an Affiliate of
Plains Resources, 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 Plains Resources.

     (d) 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.

     (e) If a Seller and Buyer determine that it is impracticable for Buyer to
purchase Crude Oil from any property owned by such Seller within the Marketing
Area, such Seller and Buyer may, by mutual written agreement with the
concurrence of the Conflicts Committee, terminate this Agreement with respect to
such properties.  Thereafter, neither such Seller nor Buyer shall have any
further obligations under this Agreement with respect to such properties.

     (f) Upon the occurrence of any of the foregoing events under subparagraphs
(a), (b), (c), (d) or (e) above, the affected Seller shall give written notice
to Buyer as soon as practicable and Exhibit A shall be revised to reflect the
effect of such event.  Upon request by any Party affected by such event, 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.

     (g) Notwithstanding the provisions of subparagraphs (a) and (b) above, the
addition of any Seller or properties to this Agreement shall be subject to any
crude oil sales contract to which such Seller or properties are bound at the
time such Seller or properties would otherwise become subject to this Agreement
(an "Existing Contract").  Accordingly, no Crude Oil shall be sold

                                       4
<PAGE>

hereunder in contravention of an Existing Contract by such Seller or from such
properties until the Existing Contract has expired or been terminated.

      2.3  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.

      2.4  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 2.4, 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.

     (a) For Crude Oil which 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 which 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.

      2.5  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 Plains Resources for the
account of the Sellers in accordance with written instructions from Plains
Resources.  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.

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.

      2.7  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
convey or 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 II.

                                 RENEGOTIATION

     Prior to the third anniversary of this Agreement, and the end of each
successive three-year period thereafter (an "Anniversary Date"), 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

Sellers or Buyer may request, in writing,  to renegotiate the Marketing and
Administrative Fee.

     (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 Anniversary 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 applicable
Anniversary Date, then this Agreement shall continue and the Marketing and
Administrative Fee shall be revised, effective the first day after the
applicable Anniversary 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) a Marketing and Administrative Fee which is less
than the Marketing and Administrative Fee last offered by Buyer; and (iii)
additional services substantially similar to those provided for in Article IV
below, this Agreement shall terminate.  Such termination shall be effective on
the next Anniversary 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 V, or until such
time that Sellers have sold their Crude Oil production to a Person who is not an
Affiliate of Sellers for a period of five (5) consecutive years.

                                    ARTICLE IV

Attention:  Mr. Timothy T. Stephens

Subject:        Crude Oil Sales Agreement dated April 1, 2001 between
                Tosco Refining Co. ("Tosco") and Plains Marketing, L.P. for
                Arroyo Grande Crude Oil (the "Tosco Agreement")

Dear Tim:

         This is to confirm our understanding and agreement that in the event
the Crude Oil Marketing Agreement ("Marketing Agreement") dated November, 1998
among Plains Marketing, L.P. ("Plains Marketing") and Plains Resources Inc., et
al., terminates prior to the termination of the Tosco Agreement, a copy of which
is attached hereto as Exhibit "A", then in such event, the parties hereby agree
that Stocker Resources, L.P.'s ("Stocker") Arroyo Grande oil production will
nonetheless continue to be committed and sold to Plains Marketing for the term
of the Tosco Agreement under the same terms and conditions as provided for in
the Marketing Agreement (except for the term thereof). Further, if there is any
conflict between the terms of the Marketing Agreement and the terms of this
agreement, the terms of this agreement shall prevail.

         No person, including Tosco (and its successors and assigns) and its
affiliates, other than the parties hereto is an intended beneficiary of this
agreement or any portion hereof. Neither this agreement nor any of the rights or
obligations hereunder may be assigned by a party without the other party's prior
written consent. Plains Marketing shall indemnify and hold harmless Stocker, and
its employees, and its controlling persons and affiliates, and their officers,
directors and stockholders, from any liability, damage, deficiency, loss,
penalty, cost or expense arising from or attributable to Plains Marketing's
performance, or failure to perform for any reason (unless such failure to
perform is caused by Stocker's failure to perform under the Marketing
Agreement), under the Tosco Agreement.
