<Page>

           one or more formulations, it may suggest such a change to the
           other Shareholder. If the Shareholders cannot agree on such a
           change of formulations, the Company shall produce and sell
           products of such new formulations to the Shareholder requesting
           the change while continuing production and sales under current
           formulations to the other Shareholder. Any net extra costs
           incurred by the Company in connection with the production and
           sales of such different formulations shall be borne by the
           Shareholder requesting the change.

           If the Shareholders cannot agree on the amount of the extra costs
           incurred by the Company in connection with the production and
           sales of such different formulations, either Shareholder may
           declare that a dispute exists and refer it for resolution under
           Article 24 below.

9.5        All agreements or other economic relations between a Shareholder,
           or an Affiliate of a Shareholder on one side and the Company on

<Page>

           agrees to assume all rights and obligations of the transferring
           Party. The Shareholders further agree that they will not transfer
           the shares of any transferee Affiliate in such a manner as to
           defeat the pre-emption right set forth in Article 16.3 below.

16.3       A Shareholder wishing to sell shares in Company may after the year
           2000 sell, all but not less than all, of the shares owned by it.

           pre-emption to the other Shareholders pursuant to the following
           provisions.

               the Company to a Third Party shall not take place without the
               consent of the other Shareholder. Such consent shall be given
               unless, in the reasonable opinion of the other Shareholder it

               assignee does not have the ability or desire to abide by this
               Agreement.

           (b) A Shareholder (the "Offeror") wishing to offer shares as
               aforesaid shall so notify the Chairman of the Board in writing
               stating the price and other terms for the proposed sale. The
               Chairman shall notify the other Shareholder (the "Offeree")
               about the offer in writing. The Offeree shall notify the
               Chairman and the Offeror within one month of receipt of such
               notification as to whether the Offeree intends to exercise its
               pre-emption right.

           (c) In the event the Offeree has notified the Chairman in a timely
               manner of its intention to exercise its pre-emption right, and
               the Shareholders cannot agree on the redemption price, the
               price shall be the fair market value at the time of
               redemption, taking into account any bona fide offer which may
               exist, as decided by one independent auditor appointed by the
               Arbitration Institute of the Stockholm Chamber of Commerce
               from one of the following accounting firms, Price Waterhouse,
               KPMG, Coopers & Lybrand, Ernst & Young or Arthur Andersen.
               Such auditor shall make his determination within sixty (60)
               days of his appointment. The determination shall be final and
               binding.

           (d) Within one week following such decision by the independent
               auditor, the Offeror shall have the right to withdraw the
               offer by written notice to the Chairman who shall so notify
               the Offeree.

                                     -13-

<Page>

           (e) In the event that the Offeror has not notified the Chairman
               as provided in the preceding paragraph but the Offeree has not
               notified the Chairman of its intention to exercise its
               pre-emption right or the Offeree has not exercised its
               pre-emption right within one month after the price has been
               decided by the auditor as aforesaid, then the Offeror shall be
               entitled to sell the shares, within two months thereafter, to
               any Third Party and provided that such Third Party agrees to
               be bound by this Agreement as provided in clause (h) below. If
               such sale does not take place within such two-month period,
               the right of pre-emption is restored.

           (f) Should a sale to a Third Party take place at a lower price than
               that offered in the aforesaid first notice to the Chairman or
               than the price decided by the independent auditor, then the
               Offeree shall be entitled to redeem the shares so sold at such
               lower price within one month after the Offeree has become
               aware of such sale and the Offeror shall be obliged to inform
               the Offeree of such sale and the price therefor. The
               Shareholders undertake to incorporate conditions to this
               effect in any sales agreement with a third party.

           (g) The aforesaid provisions shall, where relevant, apply also as
               regards subscription and participation rights.

           (h) The selling Shareholder shall ascertain that the buyer assumes
               all rights and obligations of the selling Shareholder under
               this Agreement in lieu of such selling Shareholder.

           (i) The provisions of this Article 16 shall, as between the
               Shareholders, apply in lieu of Section 11 of the By-Laws.

16.4       OKP shall have the right, notwithstanding the other provisions of
           this Article 16, to transfer a total of less than one-half of its
           shares in the Company to Svenska Lantmannen ("SLR") and/or to OK
           Marknadservice ("OKM"). If so, SLR and/or OKM shall have the
           status of Shareholders under this Agreement with a PRO RATA share,
           but OKP and SLR and/or OKM shall jointly exercise their voting
           rights at Shareholders' meetings and any other right to vote,
           appoint or nominate. In the event of such transfer, OKP shall
           unconditionally guaranty the full performance by SLR and/or OKM of
           all of their obligations under this Agreement. A condition of such
           transfer shall

                                     -14-
<Page>

           be that SLR and/or OKM grant to OKP an irrevocable proxy for all
           of their voting rights as Shareholders.

         Preem Petroleum AB ("Preem"), Reg. No. 556072-6977, Hydro Texaco
         Holdings A/S ("Hydro Texaco"), Reg. No. A/S 219.683 and Goteborgs
         Smorjmedelsfabrik (Scanlube) AB ("Scanlube"), Reg. No. 556287-6481
         hereby in writing confirm the following agreement concluded between
         the parties in July 1996 and recorded in a letter of 31 July 1996 from
         Preem and Hydro Texaco to the European Commission in
         Case No. IV/E-3/35841.

         1.     BACKGROUND

         Preem and Hydro Texaco concluded on 22 November 1995 inter alia a
         Shareholders' Agreement and on the same day an Operating and Supply
         Agreement was concluded between Preem, Hydro Texaco and Scanlube. The
         agreements were notified, as a part of a structural joint venture, to
         the European Commission on 30 November 1996. After discussions with
         the Commission the Parties decided to modify the two agreements.

         2.     THE SHAREHOLDERS' AGREEMENT

         Preem and Hydro Texaco have agreed to modify the Shareholders'
Agreement as follows

         -     delete in Art. 1.2 the sentence "The Company may also produce
               other automotive-related chemicals, such as coolants and wiper
               fluid, and other chemicals, when agreed by the Shareholders,
               which agreement shall not be unreasonably withheld.";

<Page>
                                                                             2

         -     delete in Art. 9.4, paragraph 1 the words "in order to achieve
               economies of scale" and the words "in excess of SEK 1 000 000
               per year", thus the concerned sentences will thereafter read:

               "It is the aim of the Company to produce and sell lubricants
               of such formulations as will be purchased by both Shareholders."

               "Any net extra costs incurred by the Company in connection with
               the production and sales of such different formulations shall be
               borne by the Shareholder requesting the change.";

         -     delete Art. 11;

         -     delete in Art. 14.2 the words "treated as variable and shall
               be" and "in proportion to liftings on a calendar month basis"
               and ", coolants or other chemicals" with a full stop after
               "seed oils",

               thus the concerned sentence will thereafter read:

               "Subject to Article 9.3 hereof, all costs for the operations
               of the Company, including but not limited to costs for financing,
               administrative overhead, services from Texaco Limited (which
               include license fees to Texaco Development Corporation) and from
               Texaco Services (Europe) Ltd. and Oleum, shall be covered by the
               Shareholders except that no license fees under the agreements
               listed in Article 12.2 shall be included in computing costs
               related to the production of rape seed oils."; and

         -    substitute Art. 17.1 for the following text:

              Article 17.1
<Page>

                                                                             3

              The aim of the cooperation between the parties concerning the
              Scanlube plant is set by this Agreement and adjoining documents
              and is to allow each party to acheive, through cost efficient
              production at the plant a significantly lowered production cost,
              it being understood that no party shall bear the cost of the
              other party when taking out volumes from the plant.

               Article 17.2

               The parties commit themselves to support the aim of the
               investment in Scanlube without their freedom of business being
               impaired, subject however to the provisions of Article 7.1 in
               Appendix E.

         3.    THE OPERATING AND SUPPLY AGREEMENT

         Preem, Hydro Texaco and Scanlube have agreed to modify the Operating
         and Supply Agreement as follows

         -     amend Art. 7.1 after "required" with the following words "as
               working instruments",

               thus the concerned sentence will thereafter read:

               "In order to operate Scanlube on an efficient and economic basis,
               periodic forecasting and an annual budget are required as working
               instruments.";

         -     let the headline of Art. 8 read "Units prices" instead of
               "Units costs"; and

         -     in Art. 8.2

               o  substitute the words "A unit cost (product price) system
                  will --" for "A unit price system will operate --",
<Page>

                                                                             4

               o  delete the paragraph (b), and

               o  delete in (c) the words "a", "cost" and the brackets around
                  price and add an "s" to list so that the text reads "lists
                  by",

               thus Article 8.2 will thereafter read:

               "A unit price system will operate to allow the Shareholders to
               identify raw material components, blending, packaging, handling
               and loading charges. Product cost will be built up for each
               product package combination each month (more often if warranted
               by raw material fluctuations):

               (a)   the values for raw materials are determined as the sum of
                     the value of each component material based on the most
                     recent invoice for that component material and exchange
                     rates from the last day of the prior month.

               (b)   (reserved)

               (c)   Scanlube will prepare complete product price lists by
                     package type and this will be available monthly to
                     Shareholders.".

         4.     MISCELLANEOUS

         Articles 18, 21, 23 and 24 of the Shareholders' Agreement shall
apply to this Agreement.
