         THIS AGREEMENT, made as of this 8th day of September, 1994, by and
between Toreador Royalty Corporation, a Delaware corporation (the "Company"),
and Peter R. Vig ("Optionee") in connection with the grant of an Incentive

                 (g)   "Incentive Option" shall mean a stock option that is
         intended to be or is denominated as an incentive stock option (within

         2.      Grant of Option and Option Period.  The Company hereby grants
to Optionee as of the date of this Agreement (the "Grant Date"), subject to the
provisions of Section 3 hereof and as hereinafter set forth, the option to
purchase 50,000 shares of Common Stock at the price of $3.25 per share (the
"Purchase Price"), at any time or (with respect to partial
   2
exercises) from time to time during a period commencing on the first
anniversary of the Grant Date and ending on September 8, 2004 (the "Option
Period"), provided that the number of shares purchasable hereunder in any
period or periods of time during which the Option is exercised shall be limited
as follows:

                 (a)  only 33 1/3% of such shares (if a fractional number,
         then the next lower whole number) are purchasable, in whole at any
         time or in part from time to time, commencing September 8, 1995, if
         Optionee is an employee of the Company or an Affiliate until that
         date;

                 (b)  an additional 33 1/3% of such shares (if a fractional
         number, then the next lower whole number) are purchasable, in whole at
         any time or in part from time to time, commencing September 8, 1996,
         if Optionee is an employee of the Company or an Affiliate until that
         date;

                 (c)  the remainder of such shares are purchasable, in
         whole at any time or in part from time to time, commencing September
         8, 1997, if Optionee is an employee of the Company or an Affiliate
         until that date.

         3.      Termination of Service.  Any provision of Section 2 hereof to
the contrary notwithstanding:

                 (a)  If Optionee ceases to be employed by the Company or
         an Affiliate "for cause" (as defined in Section 6.4(a) of the Plan),
         then that portion, if any, of this Incentive Option that remains
         unexercised, including that portion, if any, that pursuant to this
         Agreement is not yet exercisable, shall automatically terminate and be
         of no further force or effect as of the date Optionee ceases to be
         employed;

                 (b)  If Optionee shall die during the Option Period while
         in the employ of the Company or an Affiliate, this Incentive Option
         may be exercised, to the extent that Optionee was entitled to exercise
         it at the date of Optionee's death, within one year after such death
         (if otherwise within the Option Period), but not thereafter, by the
         executor or administrator of the estate of Optionee or by the person
         or persons who shall have acquired this Incentive Option directly from
         Optionee by bequest or inheritance;

                 (c)  If Optionee ceases to be employed by the Company or
         an Affiliate by reason of disability (as defined in Section 22(e)(3)
         of the Code), this Incentive Option may be exercised, to the extent
         that Optionee was entitled to exercise it at the date of his
         termination, within one year after such termination (if otherwise
         within the Option Period), but not thereafter by Optionee (or
         Optionee's legal representative, if Optionee is legally incompetent);
         and

                 (d)  If Optionee ceases to be employed by the Company or
         an Affiliate for any reason (other than the circumstances specified in
         paragraphs (a), (b) and (c) of this Section 3) within the Option
         Period, this Incentive Option may be exercised, to


                                     -2-
   3
         the extent Optionee was able to do so at the date of termination of
         the directorship, within three (3) months after such termination (if
         otherwise within the Option Period), but not thereafter.

         4.   Exercise During Employment.  Except as provided in Section 3
hereof, this Incentive Option may not be exercised unless Optionee is at the
time of exercise an employee of the Company or an Affiliate.

         5.   Manner of Exercise.  This Incentive Option may be exercised by
written notice signed by the person entitled to exercise same and delivered to
the Secretary of the Company or sent by United States registered mail addressed
to the Company (for the attention of the Secretary) at its corporate office in
Dallas, Texas.  Such notice shall state the number of shares of Common Stock as
to which the Incentive Option is exercised and shall be accompanied by the full
amount of the purchase price of such shares.  Exercise of this Incentive Option
shall not be effective until the Company has received written notice of
exercise.

         6.   Payment.  The Purchase Price for the Incentive Option shares
may be paid in cash by certified or cashier's check or, with the consent of the
Committee, with shares of Common Stock owned by Optionee which have been held
at least six (6) months prior to the date of exercise or, with the consent of
the Committee, by a combination of cash and such shares.

         7.   Delivery of Shares.  Delivery of the certificates representing
the shares of Common Stock purchased upon exercise of this Incentive Option
shall be made promptly after receipt of notice of exercise and payment.  If the
Company so elects, its obligation to deliver shares of Common Stock upon the
exercise of this Incentive Option shall be conditioned upon its receipt from
the person exercising this Incentive Option of an executed investment letter,
in form and content satisfactory to the Company and its legal counsel,
evidencing the investment intent of such person and such other matters as the
Company may reasonably require.  If the Company so elects, the certificate or
certificates representing the shares of Common Stock issued upon exercise of
this Incentive Option shall bear a legend in substantially the following form:

         THE SHARES OF STOCK EVIDENCED BY THIS CERTIFICATE HAVE BEEN ISSUED TO
         THE REGISTERED OWNER IN RELIANCE UPON WRITTEN REPRESENTATIONS THAT
         THESE SHARES HAVE BEEN PURCHASED FOR INVESTMENT.  THESE SHARES MAY NOT
         BE SOLD, TRANSFERRED, OR ASSIGNED UNLESS, IN THE OPINION OF THE
         CORPORATION OR ITS LEGAL COUNSEL, SUCH SALE, TRANSFER, OR ASSIGNMENT
         WILL NOT BE IN VIOLATION OF THE SECURITIES ACT OF 1933, AS AMENDED,
         APPLICABLE RULES AND REGULATIONS OF THE SECURITIES AND EXCHANGE
         COMMISSION, AND ANY APPLICABLE STATE SECURITIES LAWS.


                                      -3-
   4
       8.   Status of Optionee.  Optionee shall not be deemed to be a
stockholder of the Company with respect to any of the shares of Common Stock
subject to this Incentive Option, except to the extent that such shares shall
have been purchased and transferred to him.  The Company shall not be required
to issue or transfer any certificates for shares of Common Stock purchased upon
exercise of this Incentive Option until all applicable requirements of law have
been complied with and such shares shall have been duly listed on any
securities exchange on which the Common Stock may then be listed.

       9.   Adjustments.  Notwithstanding any other provision hereof, in the
event of any change in the number of outstanding shares of Common Stock
effected without receipt of consideration therefor by the Company, by reason of
a stock dividend, or split, combination, exchange of shares or other
recapitalization, merger, or otherwise, in which the Company is the surviving
corporation, the number and class of shares subject to this Incentive Option
and the exercise price of this Incentive Option shall be automatically adjusted
to accurately and equitably reflect the effect thereupon of such change,
provided that any fractional share resulting from such adjustment may be
eliminated.  In the event of a dispute concerning such adjustment, the decision
of the Committee shall be conclusive.  The number of shares subject to this
Incentive Option shall be automatically reduced by any fraction included
therein which results from any adjustment made pursuant to this Section 9.

       A dissolution or liquidation of the Company; a sale of all or
substantially all of the assets of the Company where it is contemplated that
within a reasonable period of time thereafter the Company will either be
liquidated or converted into a nonoperating company or an extraordinary
dividend will be declared resulting in a partial liquidation of the Company
(but in all cases only with respect to those employees with the Company and its
Affiliates as a result of such sale or assets); a merger or consolidation
(other than a merger effecting a reincorporation of the Company in another
state or any other merger or a consolidation in which the shareholders of the
surviving corporation and their proportionate interests therein immediately
after the merger or consolidation are substantially identical to the
shareholders of the Company and their proportionate interests therein
immediately prior to the merger or consolidation) in which the Company is not
the surviving corporation (or survives only as a subsidiary of another
corporation in a transaction in which the shareholders of the parent of the
Company and their proportionate interests therein immediately after the
transaction are not substantially identical to the shareholders of the Company
and their proportionate interests therein immediately prior to the
transaction); or a transaction in which another corporation becomes the owner
of 50% or more of the total combined voting power of all classes of stock of
the Company shall cause this Incentive Option to terminate, but Optionee shall,
in any event, have the right, immediately prior to such dissolution,
liquidation, merger, consolidation, or transaction, to exercise this Incentive
Option, to the extent not theretofore exercised, without regard to the
determination as to the periods and installments of exercisability made
pursuant to Section 3 hereof if (and only if) this Incentive Option has not at
that time expired or been terminated.  Such acceleration of exercisability
shall not apply to this Incentive Option if any surviving or acquiring
corporation agrees to assume this Incentive Option in connection with the
merger, consolidation, or transaction.


                                      -4-

       10.  Committee Authority.  Any questions concerning the
interpretation of this Agreement and any controversy which may arise under this
Agreement shall be determined by the Committee in its sole discretion.

       11.  Transferability.  This Incentive Option is not transferable
otherwise than by will and the laws of descent and distribution and during the
lifetime of Optionee is exercisable only by Optionee or, if Optionee is legally
incompetent, by Optionee's legal representative.

       12.  Employment.  Nothing in this Agreement confers upon Optionee any
right to continue in the employ of the Company or any Affiliate, nor shall this
Agreement interfere in any manner with the right of the Company or any
Affiliate to terminate the employment of Optionee with or without cause at any
time.

       13.  Incentive Option Subject to Plan.  By execution of this
Agreement, Optionee agrees that this Incentive Option and the shares of Common
Stock to be received upon exercise hereof shall be governed by and subject to
all applicable provisions of the Plan.

       14.  Construction.  This Agreement is governed by, and shall be
construed and enforced in accordance with, the laws of the State of Texas.
Words of any gender used in this Agreement shall be construed to include any
other gender, unless the context requires otherwise.  The headings of the
various sections of this Agreement are intended for convenience of reference
only and shall not be used in construing the terms hereof.

       IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the date first above written.

         Re: Amendment to Stock Option Agreements under the 1990 
             Stock Option Plan

Dear Peter:

         Reference is made to that certain Incentive Stock Option Agreement
dated as of September 8, 1994 (the "Incentive Agreement"), between you and
Toreador Royalty Corporation (the "Company") under the Company's 1990 Stock
Option Plan.  The Stock Option Committee of the Board of Directors has
authorized an amendment to the Incentive Agreement to allow for accelerated
vesting of options granted under the Plan upon the occurrence of a change in
control of the Company.

         Accordingly, Section 9 of the Incentive Agreement is hereby amended
effective as of April 25, 1995 by deleting such section in its entirety and
inserting in its place a new Section 9, which shall be and read as follows:

         9.      Adjustments Upon Changes in Capitalization, Merger, Etc.  In
         the event that, before delivery by the Company of all of the shares of
         Common Stock in respect of which this Incentive Option has been
         granted, the Company shall have effected a split of the Common Stock,
         a dividend payable in Common Stock, or combination of Common Stock
         into a smaller number of shares, the shares still subject to the
         Incentive Option shall be increased or decreased proportionately and
         the purchase price per share shall be decreased or increased
         proportionately so that the aggregate purchase price for all of the
         shares then subject to the Incentive Option shall remain the same as
         immediately prior to such split, dividend or combination.

         In the event of a reclassification of Common Stock not covered by the
         foregoing, or in the event of a liquidation or reorganization
         (including a merger, consolidation or sale of assets) of the Company,
         the Board shall make such adjustments, if any, as it may deem
         appropriate in the number, purchase

         price and kind of shares covered by the unexercised portions of the
         Incentive Option.  The provisions of this Section 9 shall only be
         applicable if, and only to the extent that, the application thereof
         does not conflict with any valid governmental statute, regulation or
         rule.

         Notwithstanding any indication to the contrary in the preceding
         paragraphs of this Section 9, upon the occurrence of a "Change in
         Control" (as hereinafter defined) of the Company, the maturity of the
         Incentive Option shall be accelerated automatically, so that the
         Incentive Option shall become exercisable in full with respect to all
         shares as to which the Incentive Option shall not have previously been
         exercised or become exercisable; provided, however, that no such
         acceleration shall occur with respect to this Incentive Option if
         Optionee's employment with the Company or an Affiliate shall have
         terminated prior to the occurrence of such Change in Control.

                       For purposes of the Plan, a "Change in Control" of
         the Company shall be deemed to have occurred if:

                       (a)     the stockholders of the Company shall approve:

                               (i)         any merger, consolidation or
                       reorganization of the Company (a "Transaction") in
                       which the stockholders of the Company immediately
                       prior to the Transaction would not, immediately after
                       the Transaction, beneficially own, directly or
                       indirectly, shares representing in the aggregate more
                       than 50% of all votes to which all stockholders of the
                       corporation issuing cash or securities in the
                       Transaction (or of its ultimate parent corporation, if
                       any) would be entitled under ordinary circumstances in
                       the election of directors, or in which the members of
                       the Company's Board immediately prior to the
                       Transaction would not, immediately after the
                       Transaction, constitute a majority of the board of
                       directors of the corporation issuing cash or
                       securities in the Transaction (or of its ultimate
                       parent corporation, if any),

                                  (ii)    any sale, lease, exchange or
                          other transfer (in one transaction or a series
                          of related transactions contemplated or 
                          arranged by any party as a single plan) of 
                          all or substantially all of the Company's 
                          assets, or

                                  (iii)    any plan or proposal for the
                          liquidation or dissolution of the Company;

                          (b)     individuals who constitute the Company's
                 Board as of the date of adoption of the Plan by the Board (the
                 "Incumbent Directors") cease for any reason to constitute at
                 least a majority of the Board; provided, however, that for
                 purposes of this subparagraph (b), any individual who becomes
                 a Director of the Company subsequent to the date of adoption
                 of the Plan by the Board, and whose election, or nomination
                 for election by the Company's stockholders, is approved by a
                 vote of at least a majority of the Incumbent Directors who are
                 Directors at the time of such vote, shall be considered an
                 Incumbent Director; or

                          (c)     any "person," as that term is defined in
                 Section 3(a)(9) of the Securities Exchange Act of 1934, as
                 amended (the "Exchange Act") (other than the Company, any of
                 its subsidiaries, any employee benefit plan of the Company or
                 any of its subsidiaries, or any entity organized, appointed or
                 established by the Company for or pursuant to the terms of
                 such plan), together with all "affiliates" and "associates"
                 (as such terms are defined in Rule 12b-2 under the Exchange
                 Act) of such person (as well as any "Person" or "group" as
                 those terms are used in Sections 13(d) and 14(d) of the
                 Exchange Act), shall become the "beneficial owner" or
                 "beneficial owners" (as defined in Rules 13d-3 and 13d-5 under
                 the Exchange Act), directly or indirectly, of securities of
                 the Company representing in the aggregate 20% or more of
                 either (i) the then outstanding shares of Common Stock or (ii)
                 the combined voting power of all then outstanding securities
                 of the Company having the right under ordinary circumstances
                 to vote in an election of the Company's Board ("Voting
                 Securities"), in either such case other than as a

                 result of acquisitions of such securities directly 
                 from the Company.

                 Notwithstanding the foregoing, a "Change in Control" of the
         Company shall not be deemed to have occurred for purposes of
         subparagraph (c) of this Section 9 solely as the result of an
         acquisition of securities by the Company which, by reducing the number
         of shares of Common Stock or other Voting Securities outstanding,
         increases (i) the proportionate number of shares of Common Stock
         beneficially owned by any person to 20% or more of the shares of
         Common Stock then outstanding or (ii) the proportionate voting power
         represented by the Voting Securities beneficially owned by any person
         to 20% or more of the combined voting power of all then outstanding
         Voting Securities; provided, however, that if any person referred to
