         information shall (i) set forth the historical production data of the
         oil and gas reserves included in such properties, (ii) set forth for
         each property prices received for production, lease operating expenses,
         capital expenditures and such other information as Bank may deem
         necessary or appropriate, (iii) set forth for each property any
         material changes since the date of most recent Reserve Report, if any,
         in Borrowers' working interest or net revenue interest therein, and
         (iv) be accompanied by a certification of Borrowers to the effect that
         no material adverse changes have occurred since the date of the last
         Reserve Report except those which have previously been disclosed to
         Bank in writing. Bank shall then determine the Borrowing Base for the
         next six (6) month period.

                  3.3 SPECIAL DETERMINATIONS OF BORROWING BASE. Special
         determinations of the Borrowing Base may be requested by Borrowers not
         more than one (1) time per calendar year or by Bank at any time during
         the term hereof. If any special determination is requested by
         Borrowers, it shall be accompanied by engineering data described in
         Section 3.2(b). If any special determination is requested by Bank,
         Borrowers will provide Bank with the information specified in Section
         3.2(b) hereof as soon as is reasonably possible following the request.
         The determination whether to increase or decrease the Borrowing Base
         shall then be made by Bank in its sole discretion in accordance with
         the standards set forth in Section 3.0 hereof. In the event of any
         special determination of the Borrowing Base pursuant to this Section,
         Bank in the exercise of its discretion may suspend the next regularly
         scheduled determination of the Borrowing Base.

                  3.4 BORROWING BASE DEFICIENCY. If by reason of any adjustment
         to the Borrowing Base, the Principal Debt then outstanding exceeds the
         amount of the Borrowing Base, then Bank shall notify Borrowers of the
         same, and Borrowers shall within thirty (30) days following receipt of
         such notice elect whether to (i) prepay an amount which will reduce the
         Principal Debt to the amount of the Borrowing Base (this sum may be
         paid in one installment or, at Borrowers' option, in three equal
         consecutive monthly installments), or (ii) execute and deliver to Bank
         instruments mortgaging such other collateral as is acceptable to Bank,
         pursuant to security documents acceptable to Bank having present values
         which, in the opinion of Bank, taken in the aggregate are sufficient to
         increase the Borrowing Base to an amount at least equal to the
         Principal Debt then outstanding, or (iii) do any combination of the
         foregoing as is acceptable to Bank. If Borrowers so elect to mortgage
         additional oil and gas properties, then clause (ii) above shall be
         accomplished within forty-five (45) days from Bank's date of
         notification. If Borrowers fail to make an election among clauses (i)
         through (iii) above within thirty (30) days from Bank's notification,

         8.0 REPRESENTATIONS AND WARRANTIES. Borrowers hereby jointly and
severally represent and warrant to Bank as follows:

                  8.1 NO LIENS. Toreador Exploration & Production Inc. has good

         oil and gas leases which are described in and covered by the
         engineering reports previously delivered to and relied upon by Bank in
         connection with this Agreement, and none of such Mineral Interests are
         subject to any security interest, mortgage, deed of trust, pledge,
         lien, title retention document or encumbrance of any character, except
         for except for (i) the contracts, agreements, burdens, encumbrances and
         other matters as may be set forth in the description of each of the

         or pay or other prepayments with respect to any of the leases described
         in the Oil and Gas Mortgages for which Borrowers are the operator which
         would require the delivery of hydrocarbons produced from such leases at
         some time in the future without then or thereafter receiving full
         payment therefor.

                  8.3 GOOD STANDING. Toreador Royalty Corporation is a
         corporation, duly organized, validly existing and in good standing

         the laws of the State of Texas. Each Borrower has the power and
         authority to own its property and to carry on its business in Texas in
         each other jurisdiction in which the character of the properties owned
         or held by it or the nature of the business transacted by it makes such
         qualification necessary.

                  8.4 AUTHORITY AND COMPLIANCE. Each Borrower has full power and
         authority to execute, deliver and perform the Loan Documents and to
         incur and perform the obligations provided for therein. No consent or
         approval of any public authority or other third party is required as a
         condition to the validity or performance of any Loan Document. Each
         Borrower is in compliance with all laws and regulatory requirements to
         which such Borrower is subject, except where failure so to comply would
         not have a material adverse effect upon the financial condition,
         properties or operations of either Borrower.

                  8.5 BINDING AGREEMENT. This Agreement and the other Loan
         Documents executed by Borrowers constitute valid and legally binding
         obligations of Borrowers, enforceable in accordance with their terms,
         except as such enforcement may be limited by bankruptcy, insolvency or
         other similar laws of general application relating to the enforcement
         of creditors' rights.

                  8.6 LITIGATION. There is no proceeding involving an amount in
         excess of $100,000 involving either Borrower pending or, to the
         knowledge of Borrowers, threatened before any court or governmental
         authority, agency or arbitration authority, except as disclosed to Bank
         in writing and acknowledged by Bank prior to the date of this
         Agreement.

                  8.7 NO CONFLICTING AGREEMENTS. There is no charter, bylaw,
         stock provision, partnership agreement or other document pertaining to
         the power or authority of either Borrower and no provision of any
         existing agreement, mortgage, indenture or contract binding on either
         Borrower or affecting either Borrower's property, which would conflict
         with or in any way prevent the execution, delivery or carrying out of
         the terms of this Agreement and the other Loan Documents.

                  8.8 TAXES. All taxes and assessments due and payable by
         Borrowers have been paid or are being Contested in Good Faith, and

         file.

                  8.9 ERISA. Borrowers are in compliance in all material
         respects with all applicable provisions of ERISA. Neither a Reportable
         Event nor a Prohibited Transaction has occurred and is continuing with
         respect to any Plan; no notice of intent to terminate a Plan has been
         filed, nor has any Plan been terminated; neither Borrower nor any
         Commonly Controlled Entity has completely or partially withdrawn from a
         Multiemployer Plan; and Borrowers and each Commonly Controlled Entity
         have met their minimum funding requirements under ERISA with respect to
         all of their Plans.

                  8.10 ACCURACY OF INFORMATION. To the best of each Borrower's
         knowledge, all factual information furnished by Borrowers to Bank in
         connection with this Agreement and the other Loan Documents is and will
         be accurate and complete on the date as of which such information is
         delivered to Bank and is not and will not be incomplete by the omission
         of any material fact necessary to make such information not misleading.

                  9.0 DEFAULT. Any of the following shall constitute events of 
         default (each and "Event of Default"):

                  9.1 NONPAYMENT. Borrowers shall default in the due and
         punctual payment of any principal or interest of the Note or any of the
         other Obligations when due and payable, whether at maturity or

                  9.2 REPRESENTATIONS AND WARRANTIES. Any representation,
         warranty or statement made by Borrowers herein or otherwise in writing

         Documents and the agreements referred to herein or therein or in any
         financial statement, certificate or statement signed by any officer or
         employee of Borrowers and furnished pursuant to any provision of the
         Loan Documents shall be breached, or shall be materially false,
         incorrect or incomplete when made.

                  9.3 CERTAIN AFFIRMATIVE AND NEGATIVE COVENANTS. (i) Either

         Borrower shall default in the due performance or observance of any
         term, covenant or agreement on its part to be observed or performed
         pursuant to Sections 6.1 or 6.3 through 6.10 hereof, and such failure
         shall continue unremedied for a period of fifteen (15) days after (a)

LOAN AGREEMENT - Page 14

   15

         default from Bank; or (b) Bank is notified of such default or should
         have been so notified pursuant to the provisions of Section 6.2 hereof,

         contained in this Agreement and such default shall continue unremedied
         for a period of thirty (30) days after: (a) notice of such default from
         Bank, or (b) Bank is notified of such default or should have been so
         notified pursuant to the provisions of Section 6.2 hereof, whichever is

         under the provisions of any instrument (other than the Loan Documents)
         evidencing indebtedness of either Borrower for the payment of borrowed
         money in excess of $50,000 or of any agreement relating thereto (the
         effect of which is to permit the holder or holders of such instrument
         to cause the indebtedness evidenced by such instrument to become due
         prior to its stated maturity).

         shall cease to be a legal, valid and binding agreement enforceable

         and such Borrower shall not discharge the same within a period of
         thirty (30) days unless, pending further proceedings, execution has not
         been commenced, or, if commenced, has been effectively stayed. Any
         order, judgment or decree shall be entered in any proceeding against
         either Borrower decreeing the dissolution or split up of such Borrower
         and such order shall remain undischarged or unstayed for a period in
         excess of thirty (30) days.

                  terminate a Plan, or the PBGC shall institute such
                  proceedings;

         and in each case above, such event or condition, together with all

indebtedness shall be forthwith due and payable without demand, presentment for
payment, notice of nonpayment, protest, notice of protest, notice of intent to
accelerate, notice of acceleration and all other notices and further actions of
any kind, all of which are hereby expressly waived by Borrowers. Upon the

(b) exercise any and all rights afforded to Bank by the laws of the State of
Texas or any other applicable jurisdiction or in equity or otherwise, as Bank
may deem appropriate.

required or may desire to give to any other party under any provision of this
Agreement must be in writing delivered to the other party at the addresses set
forth on the first page of this Agreement or to such other address as any party
may designate by written notice to the other party. Each such notice, request
and demand shall be deemed given or made (a) if sent by hand delivery or private
carrier, upon delivery; and (b) if sent by mail, upon the earlier of the date of
receipt or five (5) days after deposit in the U.S. Mail, first class postage
prepaid.

         12.0 COSTS, EXPENSES, ATTORNEYS' FEES, AND INDEMNITY. Borrowers shall
pay to Bank immediately upon demand the full amount of all costs and expenses,
including reasonable attorneys' fees, incurred by Bank in connection with (a)
negotiation and preparation of this Agreement and each of the Loan Documents,
and (b) any modifications of or consents or waivers under or amendments to or
interpretations of or the enforcement of this Agreement, the Note, the other
Loan Documents and the agreements described therein, and the collection of the
Obligations. Borrowers further agree to indemnify Bank from and hold it harmless
against any and all losses, liabilities, claims, damages or expenses which Bank
suffers or incurs as a result of its entering into this Agreement, or the
consummation of the transactions contemplated by this Agreement and the Loan
Documents, or the use or contemplated use of the proceeds of the Loan,
including, without limitation, the fees and disbursements of counsel incurred in
connection with any litigation, arbitration or other proceeding arising out of
or by reason of any of the after said; provided that no Borrower shall be
obligated under this Section to indemnify Bank for that portion, if any, of such
losses, liabilities, claims, damages or 



LOAN AGREEMENT - Page 16

   17

expenses which are caused by Bank's own negligence. Borrowers shall defend any
claim for which Bank is entitled to seek indemnity pursuant to the preceding
sentence, and Bank shall cooperate with the defense. Bank may have separate
counsel, and Borrowers will pay the expenses and reasonable fees of such
separate counsel if either counsel for Borrowers or counsel for Bank shall
advise Bank that the interests of both Borrowers and Bank with respect to such
claim are or with reasonable certainty will become adverse.

         13.0 MISCELLANEOUS. Borrowers and Bank further covenant and agree as
follows, without limiting any requirement of any other Loan Document:

         13.1 CUMULATIVE RIGHTS AND NO WAIVER. Each and every right granted to
Bank under any Loan Document, or allowed it by law or equity shall be cumulative
of each other and may be exercised in addition to any and all other rights of
Bank, and no delay in exercising any right shall operate as a waiver thereof,
nor shall any single or partial exercise by Bank of any right preclude any other
or future exercise thereof or the exercise of any other right. Borrowers
expressly waive any presentment, demand, protest or other notice of any kind,
including but not limited to notice of intent to accelerate and notice of
acceleration. No notice to or demand on Borrowers in any case shall, of itself,
entitle Borrowers to any other or future notice or demand in similar or other
circumstances.

         13.2 CHOICE OF LAW AND VENUE. THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS (BUT NOT THE RULES GOVERNING CONFLICTS
OF LAWS) OF THE STATE OF TEXAS AND SHALL BE PERFORMABLE IN DALLAS COUNTY, TEXAS.

         13.3 AMENDMENT. No modification, consent, amendment or waiver of any
provision of this Agreement, nor consent to any departure by Borrowers
therefrom, shall be effective unless the same shall be in writing and signed by
an officer of Bank, and then shall be effective only in the specified instance
and for the purpose for which given. This Agreement is binding upon Borrowers,
their successors and assigns, and inures to the benefit of Bank, its successors
and assigns; however, no assignment or other transfer of Borrowers' rights or
obligations hereunder shall be made or be effective without Bank's prior written
consent, nor shall it relieve Borrowers of any obligations hereunder. There is
no third party beneficiary of this Agreement.

         13.4 DOCUMENTS. All documents, certificates and other items required
under this Agreement to be executed and/or delivered to Bank shall be in form
and content satisfactory to Bank and its counsel.

         13.5 PARTIAL INVALIDITY. The unenforceability or invalidity of any
provision of this Agreement shall not affect the enforceability or validity of
any other provision herein and the invalidity or unenforceability of any
provision of any Loan Document to any person or circumstance shall not affect
the enforceability or validity of such provision as it may apply to other
persons or circumstances.

         13.6 SURVIVABILITY. All covenants, agreements, representations and
warranties made herein or in the other Loan Documents shall survive the making
of the Loan and shall continue in full force and effect so long as the
Obligations are outstanding or the obligation of Bank to make any advances
hereunder shall not have expired.

         13.7 JOINT AND SEVERAL LIABILITY. The obligations of Borrowers
hereunder and under all of the other Loan Documents are joint and several in all
respects.

INC., a Texas corporation having its principal place of business at 530 Preston
Commons West, 8117 Preston Road, Dallas, Texas 75225, collectively referred to
herein as the "Borrowers," promise to pay to the order of COMPASS BANK, a state
banking association and referred to herein as the "Lender," the principal sum of
Ten Million Dollars ($10,000,000) or, if less, all such sums as may have been
advanced and be outstanding hereunder, together with interest on the unpaid
principal balance as set forth below. All sums hereunder are payable to the
Lender at its principal office in Dallas, Dallas County, Texas.

         1. DEFINITIONS. Unless the context hereof otherwise requires or
provides, the terms used herein defined in that certain Loan Agreement among the
Borrowers and the Lender of even date herewith, as the same has been or may be
amended or supplemented from time to time (the "Agreement") have the same
meanings. In addition, "MAXIMUM RATE" means the higher of the maximum interest
rate allowed by applicable United States or Texas law as amended from time to
time and in effect on the date for which a determination of interest accrued
hereunder is made. The determination of the maximum rate permitted by applicable
Texas law shall be made pursuant to the indicated rate ceiling as defined in
Tex.Rev.Civ.Stat.Ann. art. 5069-1D.003, but the Lender reserves the right to
implement from time to time any other rate ceiling permitted by such law.

         2. INTEREST RATE.

         (a) The unpaid principal balance from time to time outstanding from the
date hereof until maturity (whether by acceleration or otherwise) shall bear
interest as is provided in the Agreement.

         (b) Interest shall be calculated at a daily rate equal to 1/365th
(1/366th in leap year) of the rate per annum specified therein, and shall be
charged and collected on the actual number of days elapsed. The rate of interest
on this Note shall change automatically, without notice to the Borrowers, as of
the opening of business on the effective date of each and every change of the
CBIR Rate charged by the Lender.

         (c) If at any time the rate of interest which this Note would bear if
the rate of interest were determined in accordance with Section 2(a) hereof
otherwise would exceed the Maximum Rate, then the rate of interest which this
Note bears shall be limited to the Maximum Rate; provided any subsequent
reductions in the interest rate determined in accordance with Section 2(a)
hereof shall not reduce the rate of interest which this Note bears below the
Maximum Rate (or if there is then no such Maximum Rate, then below the sum of
the CBIR Rate plus 5%) until the total amount of the interest


   21




paid and accrued on this Note equals the amount of interest which would have
been paid or accrued if the interest rate determined in accordance with Section
2(a) hereof had at all times been in effect.

         (d) All past-due payments of principal and interest under this Note
shall bear interest at the Maximum Rate (or if there is no such Maximum Rate,
then at the CBIR Rate plus 5%) from maturity until paid.

         3. PAYMENT OF INTEREST AND PRINCIPAL.

         (a) Interest hereunder shall be payable quarterly as it accrues on the
first day of each calendar quarter commencing on January 1, 1998, and at
maturity (whether by acceleration or otherwise) and after maturity on demand.

         (b) The outstanding principal hereof, plus accrued but unpaid interest
to the date of payment, shall be due and payable on October 1, 2000.

         (c) The principal and interest due hereunder shall be evidenced by the
Lender's records which, absent manifest error, shall be conclusive evidence of
the computation of principal and interest balances owed by the Borrowers to the
Lender.

         4. DEFAULT. Upon the occurrence of an Event of Default described in
Section 9.8 of the Agreement, the entire principal of and accrued interest on
this Note shall forthwith be due and payable without demand, presentment for
payment, notice of nonpayment, protest, notice of protest, notice of intent to
accelerate, notice of acceleration and all other notices and further actions of
any kind, all of which are hereby expressly waived by the Borrowers. Should any
other Event of Default occur and be continuing, the holder of this Note may,
without demand or notice of its election declare the entire unpaid balance of
this Note, or any part thereof, immediately due and payable, whereupon the
principal of and accrued interest on such Note shall be forthwith due and
payable without demand, presentment for payment, notice of nonpayment, protest,
notice of protest, notice of intent to accelerate, notice of acceleration and
all other notices and further actions of any kind, all of which are hereby
expressly waived by the Borrowers.

         5. WAIVER. Each surety, endorser, guarantor and any other party now or
hereafter liable for the payment of this Note in whole or in part ("Surety") and
the Borrowers hereby severally (a) waive grace, demand, presentment for payment,
notice of nonpayment, protest, notice of protest, non-payment or dishonor,
notice of intent to accelerate, notice of acceleration and all other notices
(except as provided in the Agreement), filing of suit and diligence in
collecting this Note or enforcing any other security with respect to same, (b)
agree to any substitution, surrender, subordination, waiver, modification,
change, exchange or release of any security or of the liability of any parties
primarily or secondarily liable hereon, (c) agree that the Lender is not
required first to institute suit or exhaust its remedies hereon against the
Borrowers, any Surety or others liable or to become liable hereon or to enforce
its rights against them or any security with respect to same, and (d) consent to
any extension or postponement of time of payment of this Note and to any other
indulgence with respect hereto without notice thereof to any of them. No failure
or delay on the part of the Lender in exercising any right, power or privilege
hereunder shall operate as a waiver thereof.

         6. ATTORNEYS' FEES. If this Note is not paid at maturity, regardless of
how such maturity may be brought about, or is collected or attempted to be
collected through the initiation or prosecution of any suit or through any
probate, bankruptcy or any other judicial proceedings, or is placed in the hands
of an attorney for collection, the Borrowers shall pay, in addition to all other
amounts owing hereunder, all actual expenses of collection, all court costs and
reasonable attorney's fees incurred by the holder hereof.

         7. LIMITATION ON AGREEMENTS. All agreements between the Borrowers and
the Lender, whether now existing or hereafter arising, are hereby limited so
that in no event shall the amount paid, or agreed to be paid to or charged or
demanded by the Lender for the use, forbearance, or detention of money or for
the payment or performance of any covenant or obligation contained herein or in
any other document evidencing, securing or pertaining to this Note, exceed the
Maximum Rate. If any circumstance otherwise would cause the amount paid, charged
or demanded to exceed the Maximum Rate, the amount paid or agreed to be paid to
or charged or demanded by the Lender shall be reduced to the Maximum Rate, and
if the Lender ever receives interest which otherwise would exceed the Maximum
Rate, such amount which would be excessive interest shall be applied to the
reduction of the principal of this Note and not to the payment of interest, or
if such excessive interest otherwise would exceed the unpaid balance of
principal of this Note such excess shall be applied first to other indebtedness
of the Borrowers to the Lender, and the balance, if any, shall be refunded to
the Borrowers. In determining whether the interest paid, agreed to be paid,
charged or demanded hereunder exceeds the highest amount permitted by applicable
law, all sums paid or agreed to be paid to or charged or demanded by the Lender
for the use, forbearance or detention of the indebtedness of the Borrowers to
the Lender shall, to the extent permitted by applicable law, (i) be amortized,
prorated, allocated and spread throughout the full term of such indebtedness
until payment in full so that the actual rate of interest on account of such
indebtedness is uniform throughout such term, (ii) be characterized as a fee,
expense or other charge other than interest, and (iii) exclude any voluntary
prepayments and the effects thereof. The terms and provisions of this paragraph
shall control and supersede every other provision of all agreements between the
Lender and the Borrowers in conflict herewith.

         8. GOVERNING LAW AND VENUE. This Note and the rights and obligations of
the parties hereunder shall be governed by the laws of the United States of
America and by the laws of the State of Texas, and is performable in Dallas
County, Texas. Chapter 15 of the Texas Credit Code (Tex.Rev.Civ.Stat.Ann. art.
5069-15.01 et seq., now known as Chapter 346 of the Texas Finance Code) does not
apply to this Note.

         9. BUSINESS DAY. If any action is required or permitted to be taken
hereunder on a Sunday, legal holiday or other day on which banking institutions
in the State of Texas are authorized or required to close, such action shall be
taken on the next succeeding day which is a business day, and, to the extent
applicable, interest on the unpaid principal balance shall continue to accrue at
the applicable rate.

         10. AGREEMENT. This Note is the Note referred to in the Agreement, and
is entitled to the benefits thereof and the security as provided for therein.
Reference is made to the Agreement and the Loan Documents for a statement of the
