22.   LAW AND ARBITRATION

22.1  This Agreement shall be governed by and construed in all respects in
      accordance with the laws of England,

22.2  Subject to the provisions of Clause 5 and Clause 16 hereof any dispute or
      difference arising in connection with this Agreement shall if possible be
      settled by mutual amicable agreement.

22.3  Should such settlement not be possible the dispute or difference shall be
      referred to Arbitration in London in accordance with the provisions of the
      Arbitration Act 1996 and any statutory modifications or re-enactments
      thereof for the time being in force and shall be referred to a single
      arbitrator (an "Arbitrator") to be appointed by the Parties hereto. If the
      Parties cannot agree upon the appointment of the single Arbitrator the
      dispute shall be settled by three Arbitrators, with Drillpetro appointing
      one Arbitrator and Westville appointing one Arbitrator and the third being
      appointed by the Chairman of the London Maritime Arbitrators Association.

22.4  If any of the appointed Arbitrators refuses or is incapable of acting, the
      Party who appointed him shall appoint a new Arbitrator in his place.

22.5  If a Party or parties fails to appoint an Arbitrator, either originally or
      by way of substitution, for two weeks after the other party or parties
      having appointed its/their Arbitrators have sent the party(ies) making
      default notice by mail or facsimile to make the appointment, the non
      defaulting Party(ies) may apply to the Chairman for the time being of the
      London Maritime Arbitrators Association to appoint an Arbitrator on behalf
      of the Party(ies) making default.

22.6  The award rendered by the Arbitration Court shall be final and binding
      upon the Parties and may if necessary be enforced by the Court or other
      competent authority in the same manner as a judgment in the Court of
      Justice.

22.7  Performance under this Agreement shall, as far as is reasonably possible,
      continue during the Arbitration proceedings.

23.   PREVAILING AGREEMENT

      If there is a conflict between any of the terms of this Agreement, and the
      terms of the Articles of Incorporation and By-Laws of the Holding Company,
      the terms of this Agreement shall prevail as between the Shareholders, and
      the Shareholders shall take all such action as shall be necessary for the
      purpose of this Clause to ensure that the terms of this Agreement prevail.
      Notwithstanding the foregoing or anything else contained herein or in any
      other Related Agreement, the Shareholders acknowledge that they and their
      respective Affiliates will jointly participate with representatives of the
      Lenders in the negotiation and preparation of the Loan Agreement. If and
      to the extent there are any

                                       22

      discrepancies or conflicts between the terms of this Agreement or other
      Related Agreements and Statements made in the Loan Agreement, then the
      Loan Agreement will control.

24.   ANNOUNCEMENTS

      No public announcement or communication (other than to the extent required
      by law or by any other regulation) concerning the transactions referred to
      in this Agreement shall be made or issued by any Party to this Agreement
      without the prior written consent of all the Parties but such approval
      shall not be unreasonably withheld or delayed.

25.   INVALIDITY

      If at any time any one or more of the provisions of this Agreement is or
      becomes invalid, illegal or unenforceable in any respect under any law or
      regulation, the validity, legality and enforceability of the remaining
      provisions of this Agreement shall not as a result be in any way affected
      or impaired.

26.   CONDITION PRECEDENT

      It is a condition precedent to the coming into effect of this Agreement
      and the Related Documents that Drillpetro shall have procured the
      assignment to the Holding Company of the Petrobras Agreement.

27.   FCPA

      The Parties recognize that Westville and Foramer are both subsidiaries of
      the U.S. Holding Company, Pride International, Inc. All parties are
      familiar with the U.S. Foreign Corrupt Practices Act ("FCPA") and its
      purposes. In particular, all parties are familiar with FCPA's prohibition
      of the payment of or the giving of anything of value, either directly or
      indirectly, by a United States Company or any of its subsidiaries to an
      official of a foreign government for the purpose of influencing an act or
      decision in his official capacity, or inducing him to use his influence
      with a foreign government to assist a company in obtaining or retaining
      business for or with or directing business to any person.

      If there is reason to believe that any monies being paid by or on behalf
      of the Joint Venture are being used for improper purposes, including, but
      not limited to, direct or indirect payments to a government official, any
      member of a ruling family, political party, government official or
      employee or agent of a government controlled oil company for the purposes
      of influencing any act which may result in any of the Project Companies or
      the Project Group obtaining or retaining business, the non-offending
      Parties shall have the right to sell or otherwise dispose of all or a part
      of their interest in the Project Company and/or any of the Project Group
      to the offending Party or Parties or any third party, subject to the
      pre-emption provisions in the Related Agreements, and any cost or expenses
      created by a forced sale or the early sale of such interest in order to
      avoid any

                                       23

      claim for violation of the FCPA shall be for the account of the offending
      Party or Parties or any third party transferee.

IN WITNESS WHEREOF this Agreement has been executed by or on behalf of the
Parties hereto the day and year first above.
