AMENDMENT LETTER TO MAY WAIVER LETTER - MILESTONE WAIVER

We refer to the waiver letter relating to various issues dated 20th May, 2003
(the "MAY WAIVER LETTER") entered into between those parties listed above and
Barclays Bank PLC.

All of the Banks, the Ancillary Bank and the Hedging Bank, have authorised the
Facility Agent to enter into this letter on their behalf.

1.   Terms defined or used in the May Waiver Letter have the same meaning in
     this letter.

2.   Barclays Bank PLC as Facility Agent for and on behalf of the Banks hereby
     waives the breach of paragraph 13(j) of the May Waiver Letter further to
     the failure by Toreador by 16th June 2003 to take the required action set
     out opposite Milestone Date "a" in the table of Milestone Dates contained
     in Schedule 3 of the May Waiver Letter.

3.   Further, the May Waiver Letter shall be amended so that the words "+ 28
     days" are inserted after the letter "a" in the first row of the table of
     Milestone Dates contained in Schedule 3 of the May Waiver Letter.

4.   Toreador undertakes:

     (i)      to pay all costs, fees, expenses and liabilities incurred in
              connection with the proposed alliance and joint bid for oil assets
              in France (as outlined in paragraph (d) of the Strategic Plan
              update letter dated 15th June 2003 and addressed to the Facility
              Agent) (the "FRENCH BID"); and

     (ii)     to indemnify and hold harmless each Obligor against all costs,
              claims, damages, expenses, losses, liabilities and penalties
              incurred or sustained by that Obligor as a consequence of the
              French Bid failing to proceed or being aborted for any

<PAGE>
              reason whatsoever including any arising by reason of the
              negligence, misrepresentation or wilful misconduct of any Obligor,
              its officers, employees or agents.

5.   Toreador expressly confirms that the performance of its obligations under
     paragraph 4 of this letter does not require the consent of Bank of Texas
     N.A. or, if required, such consent has been obtained.

6.   Save as amended by paragraph 3 above, the May Waiver Letter and every
     clause thereof shall continue in full force and effect.

7.   Nothing in this letter shall affect any right of any Finance Party, or any
     obligation of any Obligor, except as expressly stated above, and each
     Obligor expressly confirms that all such rights and obligations shall
     continue in full force and effect except to the extent so stated.

8.   This letter may be executed in any number of counterparts and all of such
     counterparts taken together shall be deemed to constitute one and the same
     instrument.

9.   This letter is a Finance Document.

10.  This letter does not create any right under the Contracts (Rights of Third
     Parties) Act 1999 which is enforceable by any person who is not a party to
     this letter.

11.  If a provision of this letter is or becomes illegal, invalid or
     unenforceable in any jurisdiction, that shall not affect:

         (i)      the legality, validity or enforceability in that jurisdiction
                  of any other provision of this letter; or

         (ii)     the legality, validity or enforceability, in other
                  jurisdictions of that or any other provision of this letter.

12.  This letter is governed by English law.
