ITEM 2.           ACQUISITION OR DISPOSITION OF ASSETS

         On December 16, 1998 Tormin, Inc. ("Tormin"), a wholly-owned subsidiary
of Toreador Royalty Corporation ("Toreador"), purchased certain oil, gas and
other mineral and royalty interests located in Alabama, Louisiana and
Mississippi (the "Assets") from Howell Petroleum Corporation ("Howell") pursuant
to a Purchase and Sale Agreement (the "Howell Agreement") dated October 28,
1998, by and between Howell and J.T. Philip Company ("JTP"). The purchase price
(the "Purchase Price") for the Assets was $13 million. The Assets are comprised
of approximately 1,775,000 gross mineral acres and 876,000 net mineral acres.
Producing interests, which make up approximately 2% of the total net acres, are
held in approximately 400 oil and gas wells. As a result of the acquisition,
which is effective November 1, 1998, Toreador estimates total proved reserves
acquired at approximately 7.95 billion cubic feet equivalents (BCFE). These
reserves are a mix of approximately 74% gas and 26% oil. The Purchase Price was
determined based on an arms-length negotiation between JTP and Howell. Tormin
acquired JTP's rights under the Howell Agreement through an assignment of JTP's
rights. Tormin paid JTP a transaction fee in respect to this transaction.

         A portion of the Purchase Price was financed through the issuance and
sale of $4 million of Toreador's Series A Convertible Preferred Stock (the
"Preferred Stock") which was sold pursuant to a Securities Purchase Agreement
(the "SPA") effective December 16, 1998, by and between Toreador and the persons
party thereto. In conjunction with the SPA, the parties entered into a
Registration Rights Agreement (the "RRA") effective December 16, 1998, among
Toreador and the persons party thereto. The Purchase Price for the Assets was
funded with the Company's cash ($4.4 million) and loans from Compass Bank,
Dallas ($8.6 million).

         SUMMARY OF THE HOWELL AGREEMENT. The following summary of the material
provisions of the Howell Agreement is not intended to be complete and is subject
to, and qualified in its entirety by reference to all of the provisions of such
agreement, a copy of which is filed as an exhibit to this Current Report on Form
8-K.

         Purchase and Sale. Pursuant to the Howell Agreement, Tormin purchased
certain oil, gas and other mineral and royalty interests and assumed certain
obligations related to the Assets. Tormin paid $13 million for the Assets,
subject to certain adjustments.

         Representations and Warranties. Howell made certain customary
representations and warranties related to corporate existence and authority.
Howell also represented that it was not aware of environmental obligations,
legal claims or threats thereof or third party claims to assets such as liens or
pledges. Howell also made certain additional representations and warranties as
well.

         Tormin also made certain customary representations and warranties.

         Title and Other Matters. Under the Howell Agreement, Howell provided a
special warranty of title to the Assets.

         Net Profits Interest. After Tormin receives $13 million in net revenue
from the Assets, Howell will be entitled to 10% of the subsequent net profits
from the Assets. The net profits interest of Howell is not an interest in the
Assets, nor does it encumber the Assets, but is


                                        2

<PAGE>   3



contractual in nature. After "payout," Howell will be entitled to quarterly
payments equal to 10% of Tormin's net profits from the Assets.

         Assumption and Indemnity. Howell acquired the Assets from the Federal
Intermediate Credit Bank of Jackson in 1993. The Assets consist of royalty
interests and non-producing mineral interests, and even though the owners of
these type interests are not generally responsible for the remediation of
environmental conditions or the plugging and abandonment of oil and gas wells,
the Federal Intermediate Credit Bank of Jackson required Howell to assume any
environmental and plugging obligations that might be the responsibility of the
bank. Howell represented to Tormin that Howell was not aware of any such
environmental or plugging obligations, but like the bank, Howell insisted that
Tormin assume and indemnify against any such environmental or plugging
obligations that might be the responsibility of Howell. Tormin also agreed to
indemnify Howell for all obligations that arise from ownership or operation of
the Assets on or after November 1, 1998. Howell agreed to indemnify Tormin for
all claims arising out of the accounting or payment of proceeds of production
with respect to the Assets before November 1, 1998.

         DESCRIPTION OF THE SPA. The following summary of the material
provisions of the SPA is not intended to be a complete and is subject to, and
qualified in its entirety by reference to, all of the provisions of such
agreement, a copy of which is filed as an exhibit to this Current Report on Form
8-K.

         Purchase and Sale of Preferred Shares. Pursuant to the SPA, Toreador
sold 160,000 shares of its Preferred Stock for $25.00 per share (aggregate
proceeds of $4 million). The shares were issued to certain accredited investors
(including four directors of Toreador) in a private placement conducted pursuant
to Section 4(2) under the Securities Act of 1933 (the "1933 Act") and Regulation
D promulgated under the 1933 Act. In addition to approval of the issuance of the
Preferred Stock by the full Board of Directors of Toreador, a Special Committee
of disinterested members of the Board of Directors unanimously approved the
terms of this sale. The Special Committee relied in part upon the opinion of an
investment banker as to the fairness of the terms to Toreador from a financial
point of view.

         Representation and Warranties.  Toreador and the purchasers each made
representations to the other customary for a transaction of this type.

         Covenants of the Company. Under the SPA, Toreador covenants to (1)
maintain its corporate existence, (2) provide certain information, (3) file a
Form D and obtain necessary "blue sky" exemptions, (4) maintain its filing
status and timely file SEC reports, (5) reserve an appropriate amount of
Toreador Common Stock for conversion, (6) not use the sale proceeds for insider
distributions and (7) qualify for and maintain listing on NASDAQ for Toreador's
Common Stock.

         DESCRIPTION OF REGISTRATION RIGHTS AGREEMENT. The following summary of
the RRA is not intended to be complete and is subject to, and qualified in its
entirety by reference to, all of the provisions of such agreement, a copy of
which is filed as an exhibit to this Current Report on Form 8-K.

         Demand Registration. Under the RRA, within 90 days of a demand by
holders of at least 26% of the outstanding Preferred Stock, Toreador must
register its Common Stock into 


                                        3

<PAGE>   4


which the Preferred Stock is convertible on Form S-3 on a "shelf" registration,
if available. The holders of Preferred Stock can demand registration only once.
Toreador must maintain the effectiveness of the registration until all shares of
Common Stock are sold or saleable without registration. Under the RRA, Toreador
agrees to bear the expenses of registration.

         Piggyback Registration. Under the RRA, if Toreador proposes a public
offering for cash (other than for an employee stock plan, a business combination
or certain other exceptions), it must also register the Common Stock into which
the Preferred Stock is convertible upon request of the holders of Preferred
Stock and certain other conditions. Toreador can also register less than all of
the Common Stock underlying the Preferred Stock if the managing underwriter
insists on limiting the number of shares sold due to market conditions.

         Obligations of the Company. Under the RRA, Toreador is obligated to (1)
prepare and file amendments and supplements to its registration statement where
necessary, (2) furnish each holder of Preferred Stock with copies of the
prospectus, (3) register or qualify under "blue sky" laws and (4) perform
various other acts to ensure compliance with state and federal securities laws
and provide the holders of Preferred Stock opportunity to sell their shares.

         Obligations of each Holder. Under the RRA, each holder of Preferred
Stock registering Toreador stock pursuant to the RRA must furnish Toreador
information about itself, discontinue disposition if a stop order is in effect,
enter into a reasonable underwriting agreement, deliver a prospectus to each
purchaser, and notify Toreador when the holder has sold all their Registrable
Securities (as defined in the Certificate of Designation).

         Indemnification. Under the RRA, Toreador promises to indemnify holders
of Preferred Stock for losses related to untrue or omitted facts in the
registration statement, provided the false information was not supplied by the
holder asserting a claim for indemnification and Toreador consented to the
settlement. Conversely, a holder of Preferred Stock who supplies false or
misleading information to Toreador that leads to liability under federal
securities laws will indemnify Toreador for such losses. The RRA also provides
for shared responsibility under certain circumstances for losses not remedied by
indemnification on the basis of relative fault. In no case, however, can a
person selling under the registration statement filed pursuant to the RRA be
found liable for an amount exceeding that person's net sales price received.

         DESCRIPTION OF CERTIFICATE OF DESIGNATION. The following summary of the
Certificate of Designation of Series A Convertible Preferred Stock of Toreador
Royalty Corporation (the "COD") is not intended to be complete and is subject
to, and qualified in its entirety by reference to, all of the provisions of such
agreement, a copy of which is filed as an exhibit to this Current Report on Form
8-K.

         Designation and Amount. Under the COD, 160,000 shares of Preferred
Stock are designated as "Series A Convertible Preferred Stock" with a stated
value of $25.00 per share (the "Stated Value").

         Dividends. Each share of Preferred Stock is entitled to annual
dividends of 9% of the Stated Value, which, at Toreador's option, may be paid
quarterly in cash, additional Preferred Stock or a combination of both. No
fractional shares of Preferred Stock may be issued by Toreador as dividends.
Instead, if a fractional share is owed, Toreador must choose, at its 


                                        4

<PAGE>   5



discretion, either to round up to the next whole number of shares or to pay cash
equal to the amount of fractional shares times the Stated Value.

         Priority. In the event of liquidation, dissolution or similar event,
holders of Preferred Stock will have preference over the Common Stock and all
other capital stock to the extent of the Stated Value of each share of Preferred
Stock plus any accrued and unpaid dividends.

         Conversion. Each holder of Preferred Stock may convert his shares into
shares of Common Stock at any time. To convert, the holder of Preferred Stock
must submit his request, his certificate and notice to the transfer agent. Each
share of Preferred Stock is convertible into shares of Common Stock at a rate
equal to the Stated Value divided by $4.00 (subject to certain adjustments
described below). Generally, Toreador must issue and deliver the Common Stock
within three business days.

         Adjustments to Conversion Price. The rate of conversion of Preferred
Stock will be adjusted to account for stock splits, stock dividends, mergers or
assets distributions. In no event will fractional shares be issued, however,
because of such adjustment.

         Optional Redemption by Company. At any time after December 1, 2001,
Toreador may elect to redeem for cash any or all shares of Preferred Stock upon
15 days notice to the extent permitted by law and its then available capital.
The optional redemption price per share is the sum of (1) the Stated Value of
the Preferred Stock plus (2) any accrued and unpaid dividends times a declining
multiplier (the "Multiplier"). The Multiplier is 103% until December 1, 2002,
102% until December 1, 2003, 101% until December 1, 2004, and 100% thereafter.

         Mandatory Redemption by the Company. Toreador must redeem for cash any
Preferred Stock outstanding on December 1, 2008, at a price equal to the Stated
Value plus any accrued and unpaid dividends on each share of Preferred Stock.

         Voting Rights. The holders of Preferred Stock generally have no voting
rights with respect to the management of Toreador. Toreador may not take an
action that adversely effects the Preferred Stock without prior approval of the
holders of a majority of the outstanding shares to Preferred Stock. If Toreador
(1) fails to pay four quarterly dividend payments or (2) fails to make a
mandatory redemption, the holders of Preferred Stock are entitled to separately,
as a class, elect one person to Toreador's Board of Directors, who shall serve
until the event of default is cured.

         DESCRIPTION OF COMPASS LOANS. The following summary of the Compass
loans is not intended to be complete and is subject to, and qualified in its
entirety by reference to, all of the provisions of such agreements, a copy of
which are filed as exhibits to this Current Report on Form 8-K.

         A portion of the Purchase Price for the Assets was funded with loans
(the "Loans") totaling $8.6 million from Compass Bank, Dallas ("Compass"). The
borrowers were Toreador for $2.7 million from an existing credit facility and
Tormin, which holds title to the assets, for $5.9 million. The Toreador credit
facility is a revolving note which matures on October 1, 2000. The Toreador
credit facility bears interest equal to the prime rate published in The Wall
Street Journal's "Money Rates" table (the "Prime Rate") charged by the lender,
which is 


                                        5

<PAGE>   6


currently 7.75% per annum, payable quarterly. The current borrowing base under
the facility is $10 million, subject to decrease depending upon the underlying
collateral value. The Tormin loan is a single advance credit facility equal to
the commitment amount of $5.9 million that matures on June 1, 2000. The Tormin
loan bears interest equal to the Prime Rate charged by the lender plus
one-quarter percent, which is currently 8%. The unpaid principal balance of the
loan shall be payable in monthly installments of $60,000 plus accrued interest.
The agreements governing the Loans contain various representations, warranties
and covenants of the borrower customary for a loan of this type. The loan is
secured by a pledge of the 64 most valuable properties within the Assets. The
Tormin loan has also been guaranteed by Toreador and its wholly-owned
subsidiary, Toreador Exploration & Production Inc., whose guaranty is limited to
its "net value." Tormin executed a $7.1 million promissory note to Toreador and
Toreador pledged that note and the shares of Tormin issued to Toreador to
further secure Toreador's guarantee.

                          SECURITIES PURCHASE AGREEMENT


         SECURITIES PURCHASE AGREEMENT (this "Agreement") by and among Toreador
Royalty Corporation, a Delaware corporation (the "Company"), and each of the
persons listed on the Schedule of Purchasers attached hereto. Such entities or
persons (and any other persons who become a party to this Agreement subsequent
to the date of this Agreement pursuant to Section 1.1) are each referred to
herein as a "Purchaser" and, collectively, as the "Purchasers".

         The Company wishes to sell to each Purchaser, and each Purchaser wishes
to buy, on the terms and subject to the conditions set forth in this Agreement,
shares (the "Preferred Shares") of the Company's Series A Convertible Preferred
Stock, par value $1.00 per share (the "Preferred Stock"). The Preferred Shares
are convertible pursuant to the terms of a Certificate of Designation relating
to the Preferred Stock, the form of which is attached hereto as Exhibit A (the
"Certificate of Designation") into shares (the "Conversion Shares") of the
Company's Common Stock, par value $0.15625 per share (the "Common Stock").
Dividends on the Preferred Shares are payable, subject to the terms and
conditions of the Certificate of Designation, in cash or, at the Company's
option, shares of Preferred Stock (the "Dividend Payment Shares"). The Preferred
Shares, the Conversion Shares, and the Dividend Payment Shares are collectively
referred to herein as the "Securities".

         The Company has agreed to effect the registration of the Conversion
Shares under the Securities Act of 1933, as amended (the "Securities Act"), upon
the occurrence of certain events set out in and pursuant to a Registration
Rights Agreement of even date herewith by and among the Company and the
Purchasers (the "Registration Rights Agreement"). The sale of the Preferred
Shares by the Company to the Purchasers will be effected in reliance upon the
exemption from securities registration afforded by the provisions of Regulation
D ("Regulation D"), as promulgated by the Securities and Exchange Commission
(the "Commission") under the Securities Act.

         The Company and the Purchasers hereby agree as follows:

1.       PURCHASE AND SALE OF PREFERRED SHARES.

         1.1   Agreement to Purchase and Sell. Upon the terms set forth herein,
the Company agrees to sell and each Purchaser agrees to purchase, the number of
Preferred Shares set forth below such Purchaser's name on the signature pages
hereof and at a purchase price equal to Twenty-Five Dollars ($25.00) times the
number of Preferred Shares purchased by such Purchaser (the "Purchase Price").
The Company may sell from time to time up to $4,000,000 of Preferred Shares,
provided, however, that at least $3,000,000 of Preferred Shares shall have been
purchased as of the date of the first sale of Preferred Shares pursuant to this
Agreement. Notwithstanding any provision of this Agreement to the contrary, the
Company may from time to time after the date of this Agreement sell, without any
consent or acknowledgment of the Purchasers signatory hereto, additional
Preferred Shares (not to exceed the $4,000,000 limitation set forth in the
preceding sentence) pursuant to the terms of this Agreement. Such additional
sales of Preferred Shares shall be accomplished through execution by such
Purchaser of a signature page to this Agreement and countersignature thereof by
the Company. Photocopies of such additional signature pages shall be delivered
to each other Purchaser. The closing of the purchase and sale of the 


<PAGE>   2
Preferred Shares will be deemed to occur when this Agreement and the other
Transaction Documents (as defined below) have been executed and delivered by
the Company and each Purchaser (which delivery may be effected by facsimile
transmission), and full payment of the Purchase Price has been made by each
Purchaser by wire transfer or immediately available funds against physical
delivery by the Company of duly executed certificates representing the
Preferred Shares purchased by such Purchaser hereunder.

         1.2   Certain Definitions. When used herein, (A) "business day" shall
mean any day on which the New York Stock Exchange and commercial banks in the
city of New York are open for business, (B) an "affiliate" of a party shall mean
any person or entity controlling, controlled by or under common control with
that party and (C) "control" shall mean, with respect to an entity, the ability
to direct the business, operations or management of such entity, whether through
an equity interest therein or otherwise.

2.       REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS.

         Each Purchaser, solely with respect to him or it, hereby makes the
following representations and warranties to the Company and agrees with the
Company that, as of the date of this Agreement:

         2.1   Authorization; Enforceability. If an entity, such Purchaser is 
duly and validly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation or organization with full power and
authority to purchase the Preferred Shares and to execute and deliver this
Agreement. This Agreement and the Registration Rights Agreement have been duly
and validly authorized, executed and delivered by or on behalf of such
Purchaser. This Agreement constitutes such Purchaser's valid and legally binding
obligation, enforceable in accordance with its terms.

         2.2   Accredited Investor; Investment Intent. Such Purchaser is an
accredited investor as that term is defined in Rule 501(a) of Regulation D, and
is acquiring the Preferred Shares solely for his or its own account for
investment purposes as a principal and not with a present view to the public
resale or distribution of all or any part thereof, except pursuant to sales that
are exempt from the registration requirements of the Securities Act and/or sales
registered under the Securities Act; provided, however that in making such
representation, such Purchaser does not agree to hold the Securities for any
minimum or specific term and reserves the right to sell, transfer or otherwise
dispose of the Securities at any time in accordance with the provisions of this
Agreement and with Federal and state securities laws applicable to such sale,
transfer or disposition.

         2.3   Information. The Company has provided such Purchaser with
information regarding the business, operations and financial condition of the
Company, and has granted to such Purchaser the opportunity to ask questions of
and receive answers from representatives of the Company, its officers,
directors, employees and agents concerning the Company and materials relating to
the terms and conditions of the purchase and sale of the Preferred Shares
hereunder. Such Purchaser understands that his or its investment in the
Preferred Shares involves a high degree of risk. Such Purchaser has sought such
accounting, legal and tax advice as he or it has considered necessary to make an
informed investment decision with respect to his or its acquisition of the
Preferred Shares.



                                        2
<PAGE>   3

         2.4   Limitations on Disposition. Such Purchaser acknowledges that,
except as provided in the Registration Rights Agreement, the Securities have not
been and are not being registered under the Securities Act and may not be
transferred or resold without registration under the Securities Act or unless
pursuant to an exemption therefrom.

         2.5   Legend. Such Purchaser understands that the certificates
representing the Securities will bear at issuance a restrictive legend in
substantially the following form:

               "The securities represented by this certificate have not been
               registered under the Securities Act of 1933, as amended (the
               "Securities Act"), or the securities laws of any state, and may
               not be offered or sold unless a registration statement under the
               Securities Act and applicable state securities laws shall have
               become effective with regard thereto, or an exemption from
               registration under the Securities Act and applicable state
               securities laws is available in connection with such offer or
               sale. Such securities are issued subject to the provisions of (i)
               the Certificate of Designation relating to the Series A
               Convertible Preferred Stock of Toreador Royalty Corporation (the
               "Company"), (ii) a Securities Purchase Agreement by and among the
               Company and the Purchasers signatory thereto (collectively, the
               "Purchasers") and (iii) a Registration Rights Agreement by and
               among the Company and the Purchasers."

               Notwithstanding the foregoing, it is agreed that, as long as
(A) the resale or transfer (including without limitation a pledge) of any of the
Securities is registered pursuant to an effective registration statement, (B)
such Securities can be sold pursuant to Rule 144 under the Securities Act ("Rule
144") and a registered broker dealer provides to the Company a customary
broker's Rule 144 letter and such Purchaser delivers to the Company a customary
seller's representation letter and a copy of any Form 144 which may have been
required to be filed by such Holder pursuant to Rule 144, or (C) such Securities
are eligible for resale under Rule 144(k), such Securities shall be issued
without any legend or other restrictive language and, with respect to Securities
upon which such legend is stamped, the Company shall issue new certificates
without such legend to the holder upon request.

         2.6   No Governmental Review. Such Buyer understands that no United
States federal or state agency or any other government or governmental agency
has passed on or made any recommendation or endorsement of the Securities or the
fairness or suitability of the investment in the Securities nor have such
authorities passed upon or endorsed the merits of the offering of the
Securities.

         2.7   Residency. Such Purchaser is a resident of that state or
jurisdiction specified on the Purchaser's signature page to this Agreement.

3.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         The Company hereby makes the following representations and warranties
to each Purchaser and agrees with such Purchaser that, as of the date of this
Agreement:

         3.1   Organization, Good Standing and Qualification. Each of the 
Company and its subsidiaries is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation or organization
and has all requisite corporate power and



                                        3
<PAGE>   4

authority to carry on its business as now conducted. Each of the Company and its
subsidiaries is duly qualified to transact business and is in good standing in
each jurisdiction in which the failure so to qualify would have a material
adverse effect on the consolidated business or financial condition of the
Company and its subsidiaries taken as a whole. The term "subsidiaries" shall
mean entities in which the Company has an equity interest of 50% or greater.

         3.2   Authorization; Consents. The Company has the requisite corporate
power and authority to enter into and perform its obligations under (i) this
Agreement, (ii) the Registration Rights Agreement and (iii) all other
agreements, documents, certificates or other instruments delivered by the
Company contemporaneously herewith (the instruments described in (i), (ii) and
(iii) being collectively referred to herein as the "Transaction Documents"), to
execute and perform its obligations under the Certificate of Designation, to
issue and sell the Preferred Shares to such Purchaser in accordance with the
terms hereof, to issue the Conversion Shares upon conversion of the Preferred
Shares in accordance with the Certificate of Designation, and to issue the
Dividend Payment Shares in accordance with the Certificate of Designation. All
corporate action on the part of the Company by its officers, directors and
stockholders necessary for (A) the authorization, execution and delivery of, and
the performance by the Company of its obligations under, the Transaction
Documents and (B) the authorization, execution and filing of, and the
performance by the Company of its obligations under, the Certificate of
Designation has been taken, and no further consent or authorization of the
Company, its Board of Directors, its stockholders, any governmental agency or
organization (other than such approval as may be required under the Securities
Act and applicable state securities laws in respect of the Registration Rights
Agreement), or any other person or entity is required (pursuant to any rule of
the National Association of Securities Dealers, Inc., other than with respect to
the listing of the Conversion Shares on the Nasdaq National Market System, or
otherwise).

         3.3   Enforcement. The Transaction Documents and the Certificate of
Designation constitute valid and legally binding obligations of the Company,
enforceable in accordance with their respective terms, except as such
enforcement may be limited by (i) applicable bankruptcy, insolvency,
reorganization or other laws of general application relating to or affecting the
enforcement of creditors' rights generally, (ii) general principles of equity
and (iii) as to indemnification under the Securities Act or Exchange Act,
principles of public policy.

         3.4   Disclosure Documents; Agreements; Financial Statements; Other
Information. The Company has filed with the Commission: (i) the Company's Annual
Report on Form 10-K for the year ended December 31, 1997, (ii) Quarterly Reports
on Form 10-Q for the quarters ended March 31, 1998, June 30, 1998 and September
30, 1998, (iii) all Current Reports on Form 8-K required to be filed with the
Commission since December 31, 1997 and (iv) the Company's definitive Proxy
Statement for its 1998 Annual Meeting of Stockholders (collectively, the
"Disclosure Documents"). Each Disclosure Document, as of the date of the filing
thereof with the Commission, conformed in all material respects to the
requirements of the Exchange Act, and the rules and regulations thereunder and,
as of the date of such filing, such Disclosure Document did not contain an
untrue statement of material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. As of their respective
dates, the financial statements of the Company included in the Disclosure
Documents complied as to form in all material respects with applicable
accounting



                                        4
<PAGE>   5


requirements and the published rules and regulations of the Commission with
respect thereto. Such financial statements have been prepared in accordance with
generally accepted accounting principles consistently applied at the times and
during the periods involved (except (i) as may be otherwise indicated in such
financial statements or the notes thereto, or (ii) in the case of unaudited
interim statements, to the extent they may exclude footnotes or may be condensed
or summary statements) and fairly present in all material respects the financial
position of the Company as of the dates thereof and the results of its
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end adjustments).

         3.5   Valid Issuance. The Preferred Shares are duly authorized and, 
when issued, sold and delivered in accordance with the terms hereof, (i) will be
duly and validly issued, fully paid and nonassessable, free and clear of any
taxes, liens, claims, preemptive or similar rights or encumbrances imposed by or
through the Company, (ii) based in part upon the representations of such
Purchaser in this Agreement, will be issued, sold and delivered in compliance
with all applicable Federal and state securities laws and (iii) will be entitled
to all of the rights, preferences and privileges set forth in the Certificate of
Designation. The Conversion Shares are duly authorized and reserved for issuance
and, when issued upon conversion of the Preferred Shares in accordance with the
terms of the Certificate of Designation, will be duly and validly issued, fully
paid and nonassessable, free and clear of any taxes, liens, claims, preemptive
or similar rights or encumbrances imposed by or through the Company. The
Dividend Payment Shares are duly authorized and, upon the issuance thereof in
accordance with the terms of the Certificate of Designation, will be duly and
validly issued, fully paid and nonassessable, free and clear of any taxes,
liens, claims, preemptive or similar rights or encumbrances imposed by or
through the Company.

         3.6   No Conflict with Other Instruments. Neither the Company nor any 
of its subsidiaries is in violation of any provisions of its charter, Bylaws or
any other governing document as amended and in effect on and as of the date
hereof or in default (and no event has occurred which, with notice or lapse of
time or both, would constitute a default) under any provision of any instrument
or contract to which it is a party or by which it is bound, or of any provision
of any Federal or state judgment, writ, decree, order, statute, rule or
governmental regulation applicable to the Company, which would have a material
adverse effect on the consolidated business or financial condition of the
Company and its subsidiaries taken as a whole. The (i) execution, delivery and
performance of this Agreement and the other Transaction Documents, (ii)
execution and filing of the Certificate of Designation, and (iii) consummation
of the transactions contemplated hereby and thereby (including without
limitation, the issuance of the Preferred Shares, and the reservation for
issuance and issuance of the Conversion Shares, and the Dividend Payment Shares)
will not result in any such violation or be in conflict with or constitute, with
or without the passage of time and giving of notice, either a default under any
such provision, instrument or contract or an event which results in the creation
of any lien, charge or encumbrance upon any assets of the Company or of any of
its subsidiaries, which violation, conflict, default, lien, charge or
encumbrance would have a material adverse affect on the consolidated business or
financial condition of the Company and its subsidiaries taken as a whole, or the
triggering of any preemptive or anti-dilution rights or rights of first refusal
or first offer on the part of holders of the Company's securities.

4.       COVENANTS OF THE COMPANY.

         4.1   Corporate Existence. The Company shall, so long as any Purchaser 
or any affiliate of such Purchaser beneficially owns any Securities, maintain
its corporate existence in good standing and shall pay all taxes owed by it when
due except for taxes which the Company reasonably disputes or as to which the
failure to pay could not reasonably be expected to have a material adverse
effect on the consolidated business or financial condition of the Company and
its subsidiaries taken as a whole.

         4.2   Provision of Information. Upon written request, the Company shall
provide each Purchaser with copies of its annual reports on Form 10-K, quarterly
reports on Form 10-Q, current reports on Form 8-K and proxy statements and other
materials sent to stockholders, in each such case promptly after the filing
thereof with the Commission, until the conversion or redemption of all of the
Preferred Shares held by such Purchaser.

         4.3   Form D; Blue-Sky Qualification. The Company agrees to file a 
Form D with respect to the Securities as required under Regulation D. The
Company shall, on or before the Closing, take such action as is necessary to
qualify the Preferred Shares for sale under applicable state or "blue-sky" laws
or obtain an exemption therefrom.

         4.4   Reporting Status. As long as any Purchaser or any affiliate of 
such Purchaser beneficially owns any Securities and until the date on which any
of the foregoing may be sold to the public pursuant to Rule 144(k) (or any
successor rule or regulation), (i) the Company shall timely file with the
Commission all reports required to be so filed pursuant to the Exchange Act and
(ii) the Company shall not terminate its status as an issuer required by the
Exchange Act to file reports thereunder even if the Exchange Act or the rules or
regulations thereunder would permit such termination.

         4.5   Reservation of Common Stock. The Company shall at all times have
authorized and reserved for issuance, free from any preemptive rights, solely
for the purpose of effecting conversions of the Preferred Shares hereunder, such
number of its shares of Common Stock as shall from time to time be sufficient to
effect the conversion of all of the Preferred Shares in full.

         4.6   Use of Proceeds. The Company shall use the proceeds from the sale
of the Preferred Shares for general corporate purposes only, in the ordinary
course of its business and consistent with past practice and shall not use such
proceeds to make a loan to any employee, officer or director of the Company or
to repurchase or pay a dividend on shares of Common Stock.

         4.7   Quotation on Nasdaq. The Company shall (i) promptly following the
Closing, take such action as may be necessary to include the Conversion Shares
on the Nasdaq National Market System, and (ii) use its best efforts to maintain
the designation and quotation, or listing, of the Common Stock on the Nasdaq
National Market System, the Nasdaq Small Cap Market, the New York Stock Exchange
or the American Stock Exchange.

5.       MISCELLANEOUS.

               5.1    Survival; Severability.  The representations, warranties, 
covenants and indemnities made by the parties herein shall survive the closing 
of this Agreement



                                        6
<PAGE>   7

notwithstanding any due diligence investigation made by or on behalf of the
party seeking to rely thereon, provided that the representations and warranties
contained herein shall survive for two (2) years following the date of this
Agreement. In the event that any provision of this Agreement becomes or is
declared by a court of competent jurisdiction to be illegal, unenforceable or
void, this Agreement shall continue in full force and effect without said
provision; provided that in such case the parties shall negotiate in good faith
to replace such provision with a new provision which is not illegal,
unenforceable or void, as long as such new provision does not materially change
the economic benefits of this Agreement to the parties.

               5.2   Successors and Assigns. The terms and conditions of this
Agreement shall inure to the benefit of and be binding upon the respective
successors and permitted assigns of the parties. Nothing in this Agreement,
express or implied, is intended to confer upon any party other than the parties
hereto or their respective successors and permitted assigns any rights,
remedies, obligations or liabilities under or by reason of this Agreement,
except as expressly provided in this Agreement. The Purchaser may assign its
rights and obligations hereunder, in connection with any private sale or
transfer of the Preferred Shares in accordance with the terms hereof, as long
as, as a condition precedent to such transfer, the transferee executes an
acknowledgment agreeing to be bound by the applicable provisions of this
Agreement, in which case the term "Purchaser" shall be deemed to refer to such
transferee as though such transferee were an original signatory hereto. The
Company may not assign it rights or obligations under this Agreement.

               5.3   Independent Nature of Purchasers' Obligations and Rights.
The obligations of each Purchaser hereunder are several and not joint with the
obligations of the other Purchasers hereunder, and no Purchaser shall be
responsible in any way for the performance of the obligations of any other
Purchaser hereunder. Nothing contained herein or in any other agreement or
document delivered herewith, and no action taken by any Purchaser pursuant
hereto or thereto, shall be deemed to constitute the Purchasers as a
partnership, an association, a joint venture or any other kind of entity, or
create a presumption that the Purchasers are in any way acting in concert with
respect to such obligations or the transactions contemplated by this Agreement.
Each Purchaser shall be entitled to protect and enforce its rights, including
without limitation the rights arising out of the Certificate of Designation,
this Agreement or the other Transaction Documents, and it shall not be necessary
for any other Purchaser to be joined as an additional party in any proceeding
for such purpose.

               5.4   No Reliance; Representations by Purchasers. Each party
acknowledges that (i) it has such knowledge in business and financial matters as
to be fully capable of evaluating this Agreement, the other Transaction
Documents and the transactions contemplated hereby and thereby, (ii) it is not
relying on any advice or representation of the other party in connection with
entering into this Agreement, the other Transaction Documents or such
transactions (other than the representations made in this Agreement or the other
Transaction Documents), (iii) it has not received from such party any assurance
or guarantee as to the merits (whether legal, regulatory, tax, financial or
otherwise) of entering into this Agreement or the other Transaction Documents or
the performance of its obligations hereunder and thereunder, and (iv) it has
consulted with its own legal, regulatory, tax, business, investment, financial
and accounting advisors to the extent that it has deemed necessary, and has
entered into this Agreement and the other Transaction Documents based



                                        7
<PAGE>   8

on its own independent judgment and on the advice of its advisors as it has
deemed necessary, and not on any view (whether written or oral) expressed by
such party.

               5.5   Injunctive Relief. The Company acknowledges that a breach
by it of its obligations hereunder will cause irreparable harm to each Purchaser
and that the remedy or remedies at law for any such breach will be inadequate
and agrees, in the event of any such breach, in addition to all other available
remedies, to an injunction restraining any breach and requiring immediate and
specific performance of such obligations without the necessity of showing
economic loss.

               5.6   Governing Law; Jurisdiction. This Agreement shall be
governed by and construed under the laws of the State of Texas without regard to
the conflict of laws provisions thereof. Each party hereby irrevocably submits
to the non-exclusive jurisdiction of the state and federal courts sitting in the
City of Dallas, Dallas County, for the adjudication of any dispute hereunder or
in connection herewith or with any transaction contemplated hereby or discussed
herein, and hereby irrevocably waives, and agrees not to assert in any suit,
action or proceeding, any claim that it is not personally subject to the
jurisdiction of any such court, that such suit, action or proceeding is brought
in an inconvenient forum or that the venue of such suit, action or proceeding is
improper.

               5.7   Counterparts. This Agreement may be executed in any number
of counterparts, each of which shall be deemed an original, and all of which
together shall constitute one and the same instrument.

               5.8   Headings. The headings used in this Agreement are used for
convenience only and are not to be considered in construing or interpreting this
Agreement.

               5.9   Notices. Any notice, demand or request required or
permitted to be given by any party to any other party pursuant to the terms of
this Agreement shall be in writing and shall be deemed given (i) when delivered
personally or by verifiable facsimile transmission (with an original to follow)
on or before 5:00 p.m., central time, on a business day or, if such day is not a
business day, on the next succeeding business day, (ii) on the next business day

                          REGISTRATION RIGHTS AGREEMENT


         REGISTRATION RIGHTS AGREEMENT (this "Agreement") by and among Toreador
Royalty Corporation, a Delaware corporation (the "Company"), and each of the
persons listed on the Schedule of Purchasers attached hereto (each referred to
herein as a "Purchaser" and, collectively, as the "Purchasers").

         The Company has agreed, on the terms and subject to the conditions set
forth in the Securities Purchase Agreement of even date herewith (the
"Securities Purchase Agreement"), to issue and sell to each Purchaser shares
(the "Preferred Shares") of the Company's Series A Convertible Preferred Stock,
par value $1.00 per share (the "Preferred Stock"). The Preferred Shares are
convertible pursuant to the Company's Certificate of Designation (the
"Certificate of Designation") into shares (the "Conversion Shares") of the
Company's Common Stock, par value $0.15625 per share (the "Common Stock"). In
order to induce the Purchasers to enter into the Securities Purchase Agreement,
the Company has agreed to provide certain registration rights under the
Securities Act of 1933, as amended (the "Securities Act"), and under applicable
state securities laws. Capitalized terms used herein and not otherwise defined
shall have the respective meanings set forth in the Securities Purchase
Agreement.

         In consideration of each Purchaser entering into the Securities
Purchase Agreement, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

1.       DEFINITIONS.

         For purposes of this Agreement, the following terms shall have the
meanings specified:

                  (a) "Closing" shall mean the date hereof;

                  (b) "Demand" means written request to the Company signed by
                  holders of 26% of the Preferred Shares outstanding for the
                  registration of the Conversion Shares;

                  (c) "Registration Deadline" means the one hundred and
                  twentieth (120th) day following a Demand;

                  (d) "Holder" means any person owning or having the right to
                  acquire, through conversion of Preferred Shares, Registrable
                  Securities, including initially each Purchaser and thereafter
                  any permitted assignee thereof;

                  (e) "Register", "registered" and "registration" refer to a
                  registration effected by preparing and filing a registration
                  statement or statements in compliance with the Securities Act
                  and pursuant to Rule 415 under the Securities Act ("Rule 415")
                  or any successor rule providing for the offering of securities
                  on a continuous or delayed basis ("Registration Statement"),
                  and the declaration or ordering of effectiveness of the
                  Registration Statement by the Securities and Exchange
                  Commission (the "Commission"); and
<PAGE>   2
                  (f) "Registrable Securities" means the Conversion Shares, and
                  any other shares of Common Stock issuable pursuant to the
                  terms of the Preferred Stock, whether as a dividend, payment
                  of a redemption price or otherwise, and any shares of capital
                  stock issued or issuable from time to time (with any
                  adjustments) in replacement of, in exchange for or otherwise
                  in respect of the Conversion Shares, including without
                  limitation any securities received by a Holder in connection
                  with an Exchange Transaction (as defined in the Certificate of
                  Designation).

         2.       DEMAND REGISTRATION.

                  (a) On or before the ninetieth (90th) day following a Demand,
the Company shall prepare and file with the Commission a Registration Statement
on Form S-3 (or if the Company is not then eligible to utilize Form S-3 for a
registration of this type, such other form as may be available to the Company)
as a "shelf" registration statement under Rule 415 covering the resale of the
number of shares of Registrable Securities then issuable on conversion of the
Preferred Shares. In addition, the Company may elect to register for resale
shares of Common Stock held by other holders. The Registration Statement shall
state, to the extent permitted by Rule 416 under the Securities Act, that it
also covers such indeterminate number of shares of Common Stock as may be
required to effect conversion of the Preferred Shares to prevent dilution
resulting from stock splits, stock dividends or similar events, or by reason of
changes in the Conversion Price in accordance with the terms of the Certificate
of Designation.

                  (b) The Company shall use its best efforts to cause the
Registration Statement to become effective as soon as practicable following the
filing thereof, but in no event later than the Registration Deadline and shall
maintain the effectiveness of the Registration Statement until the earlier to
occur of (i) the date on which all of the Registrable Securities have been sold
pursuant to the Registration Statement and (ii) the date on which all of the
remaining Registrable Securities (in the reasonable opinion of counsel to the
Company) may be immediately sold to the public without registration and without
regard to the amount of Registrable Securities which may be sold by a Holder
thereof at a given time (the "Registration Period").

                  (c) Upon the declaration by the Commission of the
effectiveness of a Registration Statement with respect to a Demand, the right of
the Holders to make a Demand pursuant to this Section 2 shall terminate and the
Company shall have no further obligation under this Section 2 to file any
additional Registration Statements on Demand. The Company's obligations under
Section 3 shall continue unaffected hereby.

         3.       PIGGYBACK REGISTRATION.

                  If at any time prior to the expiration of the Registration
Period, (i) the Company proposes to register shares of Common Stock under the
Securities Act in connection with the public offering of such shares for cash
(other than a registration relating solely to the sale of securities to
participants in a Company stock plan or employee stock award or a registration
on Form S-4 under the Securities Act or any successor or similar form
registering stock issuable upon a reclassification, a business combination
involving an exchange of securities or an exchange offer for securities of the
issuer or another entity) (a "Proposed Registration") and (ii) a registration
statement covering the sale of all of the Registrable


                                      - 2 -

<PAGE>   3
Securities is not then effective and available for sales thereof by the Holders,
the Company shall, at such time, promptly give each Holder written notice of
such Proposed Registration. Each Holder shall have thirty (30) days from its
receipt of such notice to deliver to the Company a written request specifying
the amount of Registrable Securities that such Holder intends to sell and such
Holder's intended method of distribution. Upon receipt of such request, the
Company shall use its best efforts to cause all Registrable Securities which the
Company has been requested to register to be registered under the Securities Act
to the extent necessary to permit their sale or other disposition in accordance
with the intended methods of distribution specified in the request of such
Holder; provided, however, that the Company shall have the right to postpone or
withdraw any registration effected pursuant to this Section 3 without obligation
to the Holder. If, in connection with any underwritten public offering for the
account of the Company, the managing underwriter(s) thereof shall impose a
limitation on the number of shares of Common Stock which may be included in the
Registration Statement because, in such underwriter(s)' judgment, marketing or
other factors dictate such limitation is necessary to facilitate public
distributions, then the Company shall be obligated to include in such
Registration Statement only such limited portion of the Registrable Securities
with respect to which each Holder has requested inclusion hereunder as such
underwriter(s) shall permit. Any exclusion of Registrable Securities shall be
made pro rata among the Holders seeking to include Registrable Securities in the
Registration Statement, in proportion to the number of Registrable Securities
sought to be included by such Holders; and provided, however, that any exclusion
of Registrable Securities shall be made pro rata with holders of other
securities having the right to include such securities in the Registration
Statement.

         4.       OBLIGATIONS OF THE COMPANY.

         In addition to performing its obligations hereunder, including those
pursuant to Sections 2(a) and 2(b) above, the Company shall:

                  (a) prepare and file with the Commission such amendments and
supplements to the Registration Statement and the prospectus used in connection
with the Registration Statement as may be necessary to comply with the
provisions of the Securities Act or to maintain the effectiveness of the
Registration Statement during the Registration Period, or as may be reasonably
requested by a Holder in order to incorporate information concerning such Holder
or such Holder's intended method of distribution;

                  (b) furnish to each Holder such number of copies of the
prospectus included in such Registration Statement, including a preliminary
prospectus, in conformity with the requirements of the Securities Act, and such
other documents as such Holder may reasonably request in order to facilitate the
disposition of such Holder's Registrable Securities;

                  (c) use all commercially reasonable efforts to register or
qualify the Registrable Securities under the securities or "blue sky" laws of
such jurisdictions within the United States as shall be reasonably requested
from time to time by a Holder, and do any and all other acts or things which may
be necessary or advisable to enable such Holder to consummate the public sale or
other disposition of the Registrable Securities in such jurisdictions; provided
that the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction;


                                      - 3 -

<PAGE>   4
                  (d) in the event of an underwritten public offering of the
Registrable Securities, enter into and perform its obligations under an
underwriting agreement, in usual and customary form reasonably acceptable to the
Company, with the managing underwriter of such offering;

                  (e) notify each Holder immediately upon the occurrence of any
event as a result of which the prospectus included in such Registration
Statement, as then in effect, contains an untrue statement of material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then
existing, and (except during a Blackout Period) as promptly as practicable,
prepare, file and furnish to each Holder a reasonable number of copies of a
supplement or an amendment to such prospectus as may be necessary so that such
prospectus does not contain an untrue statement of material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in light of the circumstances then existing.
For purposes hereof, "Blackout Period" means such day or days, not to exceed an
aggregate of thirty (30) days during any period of twelve (12) consecutive
months, with respect to which the Board of Directors of the Company determines
in good faith (A) that an amendment or supplement to the Registration Statement
or prospectus contained therein is necessary, in light of subsequent events, in
order to correct a material misstatement made therein or to include information
the absence of which would render the Registration Statement or such prospectus
materially misleading and (B) that the filing of such amendment or supplement
would result in the disclosure of information which the Company has a bona fide
business purpose for preserving as confidential; provided that the Company shall
be entitled to impose no more than three (3) Blackout Periods during any period
of twelve (12) consecutive months;

                  (f) use all commercially reasonable efforts to prevent the
issuance of any stop order or other order suspending the effectiveness of such
Registration Statement and, if such an order is issued, to obtain the withdrawal
thereof at the earliest possible time and to notify each Holder of the issuance
of such order and the resolution thereof;

                  (g) furnish to each Holder, on the date that such Registration
Statement becomes effective, a letter, dated such date, of outside counsel
representing the Company (and reasonably acceptable to such Holder) addressed to
such Holder, confirming the effectiveness of the Registration Statement and, to
the knowledge of such counsel, the absence of any stop order;

                  (h) provide each Holder and its representatives the
opportunity to conduct a reasonable inquiry of the Company's financial and other
records during normal business hours and make available its officers, directors
and employees for questions regarding information which such Holder may
reasonably request in order to fulfill any due diligence obligation on its part;
and

                  (i) permit counsel for each Holder (at such Holder's expense)
to review such Registration Statement and all amendments and supplements thereto
a reasonable period of time prior to the filing thereof with the Commission.

         5.       OBLIGATIONS OF EACH HOLDER.

         In connection with the registration of the Registrable Securities
pursuant to the Registration Statement, each Holder shall:

                  (a) furnish to the Company such information regarding itself
and the intended method of disposition of Registrable Securities as the Company
shall reasonably request in order to effect the registration thereof;

                  (b) upon receipt of any notice from the Company of the
happening of any event of the kind described in Sections 4(e) or 4(f),
immediately discontinue disposition of Registrable Securities pursuant to the
Registration Statement until the filing of an amendment or supplement as
described in Section 4(g) or withdrawal of the stop order referred to in Section
4(f);

                  (c) in the event of an underwritten offering of the
Registrable Securities, enter into a customary and reasonable underwriting
agreement and execute such other documents as the managing underwriter for such
offering may reasonably request;

                  (d) to the extent required by applicable law, deliver a
prospectus to each purchaser of Registrable Securities; and

                  (e) notify the Company when it has sold all of the Registrable
Securities theretofore held by it.

         6.       INDEMNIFICATION.

         In the event that any Registrable Securities are included in a
Registration Statement under this Agreement:

                  (a) To the extent permitted by law, the Company shall
indemnify and hold harmless each Holder, the officers, directors, employees,
agents and representatives of such Holder, and each person, if any, who controls
such Holder within the meaning of the Securities Act or the Securities Exchange
Act of 1934, as amended (the "1934 Act"), against any losses, claims, damages,
liabilities or reasonable out-of-pocket expenses (whether joint or several)
(collectively, including legal or other expenses reasonably incurred in
connection with investigating or defending same, "Losses"), insofar as any such
Losses arise out of or are based upon (i) any untrue statement or alleged untrue
statement of a material fact contained in such Registration Statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, or (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading. The Company will reimburse such Holder, and each such
officer, director, employee, agent, representative or controlling person for any
legal or other expenses as reasonably incurred by any such entity or person in
connection with investigating or defending any Loss; provided, however, that the
foregoing indemnity shall not apply to amounts paid in settlement of any Loss if
such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld), nor shall the Company be obligated to
indemnify any person for any Loss to the extent that such Loss arises out of or
is based upon and in conformity with written information furnished by such
person expressly


                                      - 5 -

<PAGE>   6
for use in such Registration Statement; and provided, further, that the Company
shall not be required to indemnify any person to the extent that any Loss
results from such person selling Registrable Securities (i) to a person to whom
there was not sent or given, at or prior to the written confirmation of the sale
of such shares, a copy of the prospectus, as most recently amended or
supplemented, if the Company has previously furnished or made available copies
thereof or (ii) during any period following written notice by the Company to
such Holder of an event described in Section 4(e) or 4(f).

                  (b) To the extent permitted by law, each Holder, acting
severally and not jointly, shall indemnify and hold harmless the Company, the
officers, directors, employees, agents and representatives of the Company, and
each person, if any, who controls the Company within the meaning of the
Securities Act or the 1934 Act, against any Losses to the extent (and only to
the extent) that any such Losses arise out of or are based upon and in
conformity with written information furnished by such Holder expressly for use
in such Registration Statement; and such Holder will reimburse any legal or
other expenses as reasonably incurred by the Company and any such officer,
director, employee, agent, representative, or controlling person, in connection
with investigating or defending any such Loss; provided, however, that the
foregoing indemnity shall not apply to amounts paid in settlement of any such
Loss if such settlement is effected without the consent of such Holder, which
consent shall not be unreasonably withheld; provided, that, in no event shall
any indemnity under this Section 6(b) exceed the net purchase price of
securities sold by such Holder under the Registration Statement.

                  (c) Promptly after receipt by an indemnified party under this
Section 6 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 6, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in and to assume the
defense thereof with counsel mutually satisfactory to the parties; provided,
however, that an indemnified party shall have the right to retain its own
counsel, with the reasonably incurred fees and expenses of one such counsel to
be paid by the indemnifying party, if representation of such indemnified party
by the counsel retained by the indemnifying party would be inappropriate under
applicable standards of professional conduct due to actual or potential
conflicting interests between such indemnified party and any other party
represented by such counsel in such proceeding. The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of
any such action, to the extent prejudicial to its ability to defend such action,
shall relieve such indemnifying party of any liability to the indemnified party
under this Section 6 with respect to such action, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section 6 or
with respect to any other action.

                  (d) In the event that the indemnity provided in subsection (a)
or (b) of this Section 6 is unavailable or insufficient to hold harmless an
indemnified party for any reason, the Company and each Holder agree, severally
and not jointly, to contribute to the aggregate Losses to which the Company or
such Holder may be subject in such proportion as is appropriate to reflect the
relative fault of the Company and such Holder in connection with the statements
or omissions which resulted in such Losses; provided, however, that in no case
shall such Holder be responsible for any amount in excess of the net purchase
price of securities sold by it under the Registration Statement. Relative fault
shall be determined by


                                      - 6 -

<PAGE>   7
reference to whether any alleged untrue statement or omission relates to
information provided by the Company or by such Holder. The Company and each
Holder agree that it would not be just and equitable if contribution were
determined by pro rata allocation or any other method of allocation which does
not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph (d), no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who is not
guilty of such fraudulent misrepresentation. For purposes of this Section 6,
each person who controls a Holder within the meaning of either the Securities
Act or the Exchange Act and each officer, director, employee, agent or
representative of such Holder shall have the same rights to contribution as such
Holder, and each person who controls the Company within the meaning of either
the Securities Act or the Exchange Act and each officer, director, employee,
agent or representative of the Company shall have the same rights to
contribution as the Company, subject in each case to the applicable terms and
conditions of this subsection (d).

                  (e) The obligations of the Company and each Holder under this
Section 6 shall survive the conversion or redemption, if any, of the Preferred
Shares, the exercise of the Warrant, the completion of any offering of
Registrable Securities pursuant to a Registration Statement under this
Agreement, or otherwise.

         7.       REPORTS.

                  With a view to making available to each Holder the benefits of
Rule 144 under the Securities Act ("Rule 144") and any other similar rule or
regulation of the Commission that may at any time permit such Holder to sell
securities of the Company to the public without registration, the Company agrees
to:

                  (a) make and keep public information available, as those terms
are understood and defined in Rule 144;

                  (b) file with the Commission in a timely manner all reports
and other documents required of the Company under the Securities Act and the
1934 Act; and

                  (c) furnish to such Holder, so long as such Holder owns any
Registrable Securities, forthwith upon request (i) a written statement by the
Company, if true, that it has complied with the reporting requirements of Rule
144, the Securities Act and the 1934 Act, (ii) a copy of the most recent annual
or quarterly report of the Company and such other reports and documents so filed
by the Company, and (iii) such other information as may be reasonably requested
in availing such Holder of any rule or regulation of the Commission which
permits the selling of any such securities without registration.

         8.       MISCELLANEOUS.

                  (a) Expenses of Registration. All expenses, other than
underwriting discounts and commissions and fees and expenses of counsel to each
Holder, incurred in connection with the registrations, filings or qualifications
described herein, including (without limitation) all registration, filing and
qualification fees, printers' and accounting fees and the fees and disbursements
of counsel for the Company shall be borne by the Company.

<PAGE>   8
                  (b) Amendment; Waiver. Any provision of this Agreement may be
amended only pursuant to a written instrument executed by the Company and
Holders of at least two thirds (2/3) of the Registrable Securities then issued
or issuable. Any waiver of the provisions of this Agreement may be made only
pursuant to a written instrument executed by the party against whom enforcement
is sought. Any amendment or waiver effected in accordance with this paragraph
shall be binding upon each Holder, each future Holder, and the Company. The
failure of any party to exercise any right or remedy under this Agreement or
otherwise, or the delay by any party in exercising such right or remedy, shall
not operate as a waiver thereof. Provided, however, that upon the issuance of
additional shares of Series A Preferred Stock subsequent to the date hereof and
in accordance with the Securities Purchase Agreement, without any further
consent or acknowledgment of the Holders party hereto, the Company may add
additional holders of Series A Preferred Stock to this Agreement from time to
time. Any such additional holders joining this Agreement shall execute a
signature page to this Agreement, which signature page shall be countersigned by
the Company and the original appended to this Agreement. A photocopy of such
appended signature page shall be sent to each prior Holder party to this
Agreement.

                           CERTIFICATE OF DESIGNATION

                                       OF

                      SERIES A CONVERTIBLE PREFERRED STOCK

                                       OF

                          TOREADOR ROYALTY CORPORATION


                         Pursuant to Section 151 of the
                        Delaware General Corporation Law


         Toreador Royalty Corporation, a corporation organized and existing
under the laws of the State of Delaware (the "Corporation"), hereby certifies
that the following resolutions were adopted by the Board of Directors of the
Corporation pursuant to authority of the Board of Directors as required by
Section 151 of the Delaware General Corporation Law.

         RESOLVED, that pursuant to the authority granted to the Board of
Directors in accordance with the provisions of the Corporation's Restated
Certificate of Incorporation, the Board of Directors hereby authorizes a series
of the Corporation's previously authorized Preferred Stock, par value $1.00 per
share (the "Preferred Stock"), and hereby states the designation and number of
shares, and fixes the relative rights, preferences, privileges and restrictions
thereof as follows:

1.       DESIGNATION AND AMOUNT.

         The designation of this series, which consists of 160,000 shares (each
such share being referred to herein as a "Preferred Share" and all such shares
being collectively referred to as the "Preferred Shares") of Preferred Stock, is
the Series A Convertible Preferred Stock (the "Series A Preferred Stock") and
the face amount shall be Twenty-Five Dollars ($25.00) per share (the "Stated
Value"). The Preferred Shares will be issued pursuant to the provisions of a
Securities Purchase Agreement by and among the Corporation and the purchasers
named therein (the "Securities Purchase Agreement").

2.       DIVIDENDS.

         (a) Dividend Rate; Payments. The holders (each, a "Holder" and
collectively, the "Holders") of Preferred Shares shall be entitled to receive,
to the extent permitted by applicable law, in preference to the payment of any
dividend on any class or series of Junior Securities (as defined below),
cumulative dividends ("Dividends") on each Preferred Share in an amount equal
to, on an annualized basis, the Stated Value of such Preferred Share times nine
percent (9%). Dividends shall accrue and cumulate on each Preferred Share from
the date of the original issuance thereof (the "Purchase Date") through the
earlier to occur of (A) the payment thereof in accordance with the terms of this
Section 2(a) and (B) the redemption or conversion of such Preferred Share in
accordance with the terms hereof. At the option of the Corporation, Dividends
may be paid in cash or may be paid, in whole or in part, by issuing additional
fully paid and nonassessable shares (the "Dividend Payment Shares") of Preferred
Stock. Accrued Dividends on each outstanding Preferred Share shall be payable

<PAGE>   2




in four quarterly installments on the last day of March, June, September and
December of each year commencing March 31, 1999 unless earlier due and payable
on a Conversion Date (as defined below) or a Redemption Date (as defined below)
(each, a "Dividend Payment Date"). If, on any date, Dividends on any outstanding
Preferred Shares have not been paid or declared by the Board of Directors in
accordance with applicable law and set aside for payment with respect to all
Dividend Payment Dates preceding such date, the aggregate amount of such
Dividends shall be fully paid or declared and set aside for payment before any
distribution, whether by way of dividend or otherwise, shall be declared, paid
or set apart with respect to any Junior Securities on or after such date.

         (b) Delivery of Dividends. The Corporation shall mail any cash
dividends declared by check to the Holder or its nominee postmarked no later
than three (3) Business Days (as defined below) following the applicable
Dividend Payment Date. If the Corporation declares any dividends payable in
Preferred Stock, the Corporation shall deliver to each Holder, on or before the
third (3rd) Business Day following the applicable Dividend Payment Date (the
"Dividend Payment Share Delivery Date"), the aggregate number of whole Dividend
Payment Shares that is determined by dividing (x) the amount of the Dividend to
which such Holder is entitled as of such Dividend Payment Date with respect to
all of such Holder's Preferred Shares by (y) the Stated Value. The Corporation
shall effect delivery of Dividend Payment Shares by delivering to the Holder or
its nominee physical certificates representing such Dividend Payment Shares, no
later than the close of business on such Dividend Payment Share Delivery Date.
No fractional Dividend Payment Shares shall be issued; the Corporation shall, in
lieu thereof, at its sole discretion, either issue a number of Dividend Payment
Shares which reflects a rounding up to the next whole number of shares or pay
cash in an amount calculated by multiplying the amount of the fractional share
times the Stated Value. Dividend Payment Shares shall be fully paid and
non-assessable, free and clear of any liens, claims, preemptive rights or
encumbrances imposed by or through the Corporation (other than restrictions on
transfer required under applicable securities laws).

3.       PRIORITY.

         (a)      Payment upon Dissolution.

                  (i) Upon the occurrence of (x) any insolvency or bankruptcy
proceedings, or any receivership, liquidation, reorganization or other similar
proceedings in connection therewith, commenced by the Corporation or by its
creditors, as such, or relating to its assets or (y) the dissolution or other
winding up of the Corporation whether total or partial, whether voluntary or
involuntary and whether or not involving insolvency or bankruptcy proceedings,
or (z) any assignment for the benefit of creditors or any marshalling of the
material assets or material liabilities of the Corporation (each, a "Liquidation
Event"), no distribution shall be made to the holders of any shares of Junior
Securities (as defined below) unless each Holder shall have received the
Liquidation Preference (as defined below) with respect to each Preferred Share
then held by such Holder. In the event that upon the occurrence of a Liquidation
Event the assets available for distribution to the Holders are insufficient to
pay the Liquidation Preference (as defined below) with respect to all of the
outstanding Preferred Shares and the preferential amounts payable to such
holders, the entire assets of the Corporation shall be distributed ratably among
the outstanding Preferred Shares in proportion to the ratio that the
preferential amount payable on each such share (which shall be the Liquidation
Preference in the case of a Preferred Share) bears to the aggregate preferential
amount payable on all such shares.



                                      -2-
<PAGE>   3





                  (ii) The "Liquidation Preference" with respect to a Preferred
Share shall mean an amount equal to the Stated Value of such Preferred Share
(subject to ratable adjustment in the event of any stock split or combination of
the Series A Preferred Stock and to equitable adjustment in the event of a
reclassification of the Series A Preferred Stock or other similar event) plus
any accrued and unpaid Dividends thereon. "Junior Securities" shall mean the
Common Stock and all other capital stock of the Corporation.

4.       CONVERSION.

         (a) Right to Convert. Each Holder shall have the right to convert, at
any time and from time to time from and after the Purchase Date, all or any part
of the Preferred Shares held by such Holder, unless previously redeemed, into
such number of fully paid and non-assessable shares of Common Stock ("Conversion
Shares") as is computed in accordance with the terms hereof (a "Conversion").

         (b) Conversion Notice. In order to convert Preferred Shares, a Holder
shall send by facsimile transmission, at any time prior to 5:00 p.m., central
time, on the date on which such Holder wishes to effect such Conversion (the
"Conversion Date"), (i) a notice of conversion (a "Conversion Notice"), in
substantially the form of Exhibit A hereto, to the Corporation and to its
designated transfer agent for the Common Stock (the "Transfer Agent") stating
the number of Preferred Shares to be converted, the applicable Conversion Price
(as defined below) and a calculation of the number of shares of Common Stock
issuable upon such Conversion and (ii) a copy of the certificate or certificates
representing the Preferred Shares being converted. The Holder shall thereafter
send the original of the Conversion Notice and of such certificate or
certificates to the Transfer Agent. The Corporation shall issue a new
certificate for Preferred Shares in the event that less than all of the
Preferred Shares represented by a certificate delivered to the Corporation in
connection with a Conversion are converted. Except as otherwise provided herein,
upon delivery of a Conversion Notice by a Holder in accordance with the terms
hereof, such Holder shall, as of the applicable Conversion Date, be deemed for
all purposes to be record owner of the Common Stock to which such Conversion
Notice relates. In the case of a dispute between the Corporation and a Holder as
to the calculation of the Conversion Price or the number of Conversion Shares or
Dividend Payment Shares issuable upon a Conversion, the Corporation shall
promptly issue to such Holder the number of Conversion Shares and Dividend
Payment Shares that are not disputed and shall submit the disputed calculations
to the Corporation's independent accountant within three (3) Business Days of
receipt of such Holder's Conversion Notice. The Corporation shall cause such
accountant to calculate the Conversion Price as provided herein and to notify
the Corporation and such Holder of the results in writing no later than three
(3) Business Days following the day on which it received the disputed
calculations. The Corporation shall deliver the Conversion Shares and Dividend
Payment Shares, if any, owed to a Holder pursuant to such accountant's
calculations on or before the close of business on the third (3rd) Business Day
following the Corporation's receipt of notice from such accountant of the
results of its calculations. Such accountant's calculation shall be deemed
conclusive absent manifest error. The fees of any such accountant shall be borne
by the party whose calculations were most at variance with those of such
accountant.

         (c) Number of Conversion Shares; Conversion Price. The number of
Conversion Shares to be delivered by the Corporation pursuant to a Conversion
shall be determined by dividing the aggregate Stated Value of the Preferred
Shares to be converted by the Conversion Price (as defined herein) in effect on
the applicable Conversion Date. Subject to 



                                      -3-
<PAGE>   4



adjustment as provided in Section 5 below, "Conversion Price" shall mean Four
Dollars ($4.00).

         (d) Certain Definitions. "Trading Day" shall mean any day on which the
Common Stock is traded on the Nasdaq National Market System or on the principal
securities exchange or market located in the United States on which the Common
Stock is then traded. "Business Day" means any day on which the New York Stock
Exchange and commercial banks located in the City of New York are open for
business.

         (e) Delivery of Common Stock Upon Conversion. Upon receipt of a
Conversion Notice from a Holder pursuant to paragraph 4(b) above, the
Corporation shall, no later than the close of business on (A) the later to occur
of (i) the third (3rd) Business Day following the Conversion Date set forth in
such Conversion Notice and (ii) the first Business Day following delivery of the
original certificates, duly endorsed, representing the Preferred Shares being
converted pursuant thereto and (B) with respect to Conversion Shares which are
disputed as described in paragraph 4(b) above, and required to be delivered by
the Corporation pursuant to the accountant's calculations described therein, the
date for delivery thereof specified in such paragraph 4(b) (the "Delivery
Date"), issue and deliver or cause to be delivered to such Holder the number of
Conversion Shares as shall be determined as provided herein. The Corporation
shall effect delivery of Conversion Shares by delivering to the Holder or its
nominee physical certificates representing such Conversion Shares, no later than
the close of business on such Delivery Date. If any Conversion would create a
fractional Conversion Share, such fractional Conversion Share shall be
disregarded and, at the Corporation's sole discretion, either the number of
Conversion Shares issuable upon such Conversion, in the aggregate, shall be the
next higher number of Conversion Shares or the Corporation shall pay cash in an
amount calculated by multiplying the amount of the fractional share times the
Conversion Price for such Conversion.

5.       ADJUSTMENTS TO CONVERSION PRICE.

         (a) Adjustment to Conversion Price Due to Stock Split, Stock Dividend,
Etc. If, prior to the Conversion of all of the Preferred Shares, (A) the number
of outstanding shares of Common Stock is increased by a stock split, a stock
dividend on the Common Stock, a reclassification of the Common Stock, the
distribution to holders of Common Stock as a class of rights or warrants
entitling them to subscribe for or purchase Common Stock at less than the then
current market price thereof (based upon the subscription or exercise price of
such rights or warrants at the time of the issuance thereof) or other similar
event, the Conversion Price shall be proportionately reduced, or (B) the number
of outstanding shares of Common Stock is decreased by a reverse stock split,
combination or reclassification of shares or other similar event, the Conversion
Price shall be proportionately increased. In such event, the Corporation shall
notify the Transfer Agent of such change on or before the effective date
thereof.

         (b) Adjustment Due to Merger, Consolidation, Etc. If, prior to the
Conversion of all of the Preferred Shares, there shall be any merger,
consolidation, business combination, tender offer, exchange of shares,
recapitalization, reorganization, redemption or other similar event, as a result
of which shares of Common Stock shall be exchanged for or changed into the same
or a different number of shares of the same or another class or classes of stock
or securities of the Corporation or another entity (an "Exchange Transaction"),
then such Holder shall (A) upon the consummation of such Exchange Transaction,
have the right to receive,



                                      -4-
<PAGE>   5




with respect to any shares of Common Stock then held by such Holder, or which
such Holder is then entitled to receive pursuant to a Conversion Notice
previously delivered by such Holder, (and without regard to whether such shares
contain a restrictive legend or are freely-tradeable) the same amount and type
of consideration (including without limitation, stock, securities and/or other
assets) and on the same terms as a holder of shares of Common Stock would be
entitled to receive in connection with the consummation of such Exchange
Transaction (the "Exchange Consideration"), and (B) upon the Conversion of
Preferred Shares occurring subsequent to the consummation of such Exchange
Transaction, the Exchange Consideration which such Holder would have been
entitled to receive in connection with such Exchange Transaction had such shares
been converted immediately prior to such Exchange Transaction, and in any such
case appropriate provisions shall be made with respect to the rights and
interests of such Holder to the end that the provisions hereof (including,
without limitation, provisions for the adjustment of the Conversion Price and of
the number of shares issuable upon a Conversion) shall thereafter be applicable
as nearly as may be practicable in relation to any securities thereafter
deliverable upon the Conversion of such Preferred Shares. The Corporation shall
not effect any Exchange Transaction unless (i) it first gives to each Holder
twenty (20) days prior written notice of such Exchange Transaction (an "Exchange
Notice"), and makes a public announcement of such event at the same time that it
gives such notice and (ii) the resulting successor or acquiring entity (if not
the Corporation) assumes by written instrument the obligations of the
Corporation hereunder, including the terms of this subparagraph 6(b), and under
the Securities Purchase Agreement and the Registration Rights Agreement
described in the Securities Purchase Agreement (the "Registration Rights
Agreement").

         (c) Distribution of Assets. If the Corporation shall declare or make
any distribution of cash, evidences of indebtedness or other securities or
assets (other than cash dividends or distributions payable out of earned surplus
or net profits for the current or the immediately preceding year), or any rights
to acquire any of the foregoing, to holders of Common Stock as a partial
liquidating dividend, by way of return of capital or otherwise, including any
dividend or distribution in shares of capital stock of a subsidiary of the
Corporation (collectively, a "Distribution"), then, upon a Conversion by a
Holder occurring after the record date for determining stockholders entitled to
such Distribution, the Conversion Price for Preferred Shares not converted prior
to the record date of a Distribution shall be reduced to a price determined by
decreasing the Conversion Price in effect immediately prior to the record date
of the Distribution by an amount equal to the fair market value of the assets so
distributed with respect to each share of Common Stock, such fair market value
to be determined by an investment banking firm selected by the Corporation.

         (d) No Fractional Shares. If any adjustment under this Section would
create a fractional share of Common Stock or a right to acquire a fractional
share of Common Stock, such fractional share shall be disregarded and, at the
Corporation's sole discretion, either the number of shares of Common Stock
issuable upon Conversion shall be the next higher number of shares or the
Corporation shall pay in cash an amount calculated by multiplying the amount of
the fractional share times the Conversion Price for such Conversion.

6.       OPTIONAL REDEMPTION BY CORPORATION.

         (a) Optional Redemption. Any time on or after December 1, 2001, the
Corporation shall have the right to redeem, in while or in part, Preferred
Shares outstanding at the Optional Redemption Price (as defined below) (an
"Optional Redemption"), to the extent permitted by applicable law and so long as
(A) the Corporation shall have sufficient cash available on the Optional
Redemption Date to effect such Optional Redemption and (B) the Corporation shall
have delivered to each Holder at least fifteen (15) Trading Days' prior written
notice (an "Optional Redemption Notice") specifying the date on which such
Optional Redemption is to be effected (the "Optional Redemption Date") and the
amount of the Optional Redemption Price payable to such Holder. If the
Corporation should elect to redeem less than all of the Preferred Shares
outstanding, the Corporation shall select those Preferred Shares to be redeemed
by lot. Nothing contained herein shall limit a Holder's right to convert its
Preferred Shares at any time prior to the Optional Redemption Date.

         (b) Optional Redemption Price. The "Optional Redemption Price" to be
paid by the Corporation to a Holder in the event of an Optional Redemption shall
be equal to the Liquidation Preference of the Preferred Shares then held by such
Holder multiplied by (i) 1.03 if the Optional Redemption Date is on or after
December 1, 2001 but before December 1, 2002, (ii) 1.02 if the Optional
Redemption Date is on or after December 1, 2002 and before December 1, 2003,
(iii) 1.01 if the Optional Redemption Date is on or after December 1, 2003 and
before December 1, 2004, or (iv) 1.00 if the Optional Redemption Date is on or
after December 1, 2004, plus in all cases, accrued and unpaid Dividends through
and including the Optional Redemption Date.

         (c) Payment of Optional Redemption Price. Upon the redemption of a
Preferred Share, payment of the Optional Redemption Price, which shall be in the
form of a Corporation check, to the Holder thereof will be effected
simultaneously with the return of such share by such Holder to the Corporation.
To the extent the Corporation shall redeem less than all of the Preferred Shares
outstanding, the Corporation shall also deliver certificates evidencing the
unredeemed Preferred Shares in addition to the Optional Redemption Price.

7.       MANDATORY REDEMPTION BY THE CORPORATION.

         (a) Mandatory Redemption. On December 1, 2008, the Corporation shall
redeem, in whole or in part, Preferred Shares outstanding in same day funds at
the Mandatory Redemption Price (as defined below) (a "Mandatory Redemption"), to
the extent permitted by applicable law and so long as the Corporation shall have
delivered to each Holder at least fifteen (15) Trading Days' prior written
notice (a "Mandatory Redemption Notice") specifying the date on which such
Mandatory Redemption is to be effected (the "Mandatory Redemption Date") and the
amount of the Mandatory Redemption Price payable to such Holder. Nothing
contained herein shall limit a Holder's right to convert its Preferred Shares at
any time prior to the Mandatory Redemption Date.

         (b) Mandatory Redemption Price. The "Mandatory Redemption Price" shall
be equal to the Liquidation Preference of the Preferred Shares being redeemed.


                                      -6-
<PAGE>   7




         (c) Payment of Mandatory Redemption Price. Upon the redemption of a
Preferred Share, payment of the Mandatory Redemption Price, which shall be in
the form of a Corporation check, to the Holder thereof will be effected
simultaneously with the return of such share by such Holder to the Corporation.

8.       MISCELLANEOUS.

         (a) Transfer of Preferred Shares. A Holder may sell or transfer all or
any portion of the Preferred Shares to any person or entity as long as such sale
or transfer is the subject of an effective registration statement under the
Securities Act or is exempt from registration thereunder and otherwise is made
in accordance with the terms of the Securities Purchase Agreement. From and
after the date of such sale or transfer, the transferee thereof shall be deemed
to be a Holder. Upon any such sale or transfer, the Corporation shall, promptly
following the return of the certificate or certificates representing the
Preferred Shares that are the subject of such sale or transfer, issue and
deliver to such transferee a new certificate in the name of such transferee.

         (b) Notices. Except as otherwise provided herein, any notice, demand or
request required or permitted to be given pursuant to the terms hereof, the form
or delivery of which notice, demand or request is not otherwise specified
herein, shall be in writing and shall be deemed given (i) when delivered
personally or by verifiable facsimile transmission on or before 5:00 p.m.,
central time, on a Business Day or, if such day is not a Business Day, on the
next succeeding Business Day, (ii) on the next Business Day after timely
delivery to an overnight courier and (iii) on the third Business Day after
deposit in the U.S. mail (certified or registered mail, return receipt
requested, postage prepaid), addressed to the parties as follows:

                  If to the Corporation:

                  Toreador Royalty Corporation
                  4809 Cole Avenue
                  Suite 108
                  Dallas, Texas 75205

and if to any Holder, to such address for such Holder as shall be designated by
such Holder in writing to the Corporation.

         (c) Lost or Stolen Certificate. Upon receipt by the Corporation of
evidence of the loss, theft, destruction or mutilation of a certificate
representing Preferred Shares, and (in the case of loss, theft or destruction)
of indemnity or security reasonably satisfactory to the Corporation, and upon
surrender and cancellation of such certificate if mutilated, the Corporation
shall execute and deliver to the Holder a new certificate identical in all
respects to the original certificate.

         (d) No Voting Rights. Except as provided by applicable law and
paragraph 8(e) below, the Holders of the Preferred Shares shall have no voting
rights with respect to the business, management or affairs of the Corporation.
The Corporation shall provide each 



                                      -7-
<PAGE>   8



Holder with prior notification of each meeting of stockholders (and copies of
proxy statements and other information sent to such stockholders).

         (e)      Protective Provisions.

                  (A) So long as shares of Series A Preferred Stock are
outstanding, the Corporation shall not, without first obtaining the approval of
the Holders of at a majority of the then outstanding shares of Series A
Preferred Stock:

                           (i) alter or change the rights, preferences or
privileges of the Series A Preferred Stock or any other capital stock of the
Corporation so as to affect adversely the Series A Preferred Stock;

                           (ii) create any new class or series of capital stock
having a preference over or ranking pari passu with the Series A Preferred Stock
as to redemption, the payment of dividends or distribution of assets upon a
Liquidation Event or any other liquidation, dissolution or winding up of the
Corporation;

                           (iii) increase the authorized number of shares of
Preferred Stock;

                           (iv) re-issue any shares of Series A Preferred Stock
which have been converted in accordance with the terms hereof; or

                           (v) declare, pay or make any provision for any cash
dividend or distribution with respect to the Common Stock of the Corporation.

                  (B) If the Corporation (i) fails to pay dividends in respect
of four quarterly dividend periods, or (ii) fails to make a Mandatory
Redemption, holders of a majority of the outstanding shares of the Preferred
Stock would be entitled acting separately as a class, to elect one person to the
Board of Directors of the Corporation. Upon the taking of such action, the
maximum authorized number of members of the Board of Directors shall
automatically increase by one person so elected, and the vacancy so created
shall be filled by the person elected pursuant to this subparagraph (B). A
director elected by the holders of Series A Preferred Stock pursuant to this
subparagraph (B) shall serve until his successor is duly elected and qualified,
until his removal or until his term terminates as provided below. Such a
director may be removed without cause at any time by action, and only by such
action, of the holders of shares of Series A Preferred Stock. If the office of a
director elected pursuant to this subparagraph (B) becomes vacant by reason of
death, resignation, retirement, disqualification, removal from office or
otherwise, such vacancy may be filled by the action, and only by such action, of
the holders of shares of Series A Preferred Stock. At such time as the event of
default giving rise to this right to elect a director has been cured, such right
shall terminate, the term of any director elected pursuant to this subparagraph
(B) shall terminate and the maximum number of authorized members of the Board of
Directors shall decrease automatically to the maximum number of authorized
members of the Board of Directors in effect immediately before any action was
taken pursuant hereto.

                          ARTICLE 2 - PURCHASE AND SALE

Agreement, and the elections of Seller under Section 2.2 hereof, Seller agrees
to sell and convey to Buyer, and Buyer agrees to purchase and pay for the Assets
and to assume the Assumed Obligations as provided for in Section 3.3.

date a fully executed copy of this agreement is actually delivered to Buyer's
office, Buyer will pay by wire transfer to Bank of Montreal Trust Company,

fails, refuses or is unable for any reason (including failure to obtain
financing) to close the transaction in accordance with the terms hereof, Seller
may, at its sole option, retain the Performance Deposit as agreed liquidated
damages and not as a penalty. In the event, however, either Buyer or Seller

Performance Deposit shall be returned as provided herein. If Closing occurs,
Seller shall credit Buyer with the amount of the Performance Deposit toward the
total Purchase Price at Closing.

         3.1 PURCHASE PRICE. Subject to adjustment as set forth in 3.1, the

Buyer assuming all plugging, replugging, abandonment, removal, disposal, and
restoration obligations, if any, as provided in Section 3.3, and acquiring the
Inventory Hydrocarbons.

         At Closing, the Purchase Price shall be reduced by lease bonus income
from leases granted after October 15, 1998, through the Closing, and by the
Performance Deposit. The adjusted purchase price, together with purchase price
adjustments, shall be paid by wire transfer in immediately available funds to
Seller or its Trust Account. Buyer shall be responsible for state sales tax, if
any.

         3.2 FINAL SETTLEMENT. Within 120 days after Closing, Seller shall
provide to Buyer, for Buyer's concurrence, an accounting (the "Final Settlement
Statement") of the actual amounts of Seller's and Buyer's credits for the
adjustments set out in this Section 3.2. Buyer shall have the right for 30 days
after receipt of the Final Settlement Statement to audit and take exceptions to
such adjustments. Any disagreements shall be resolved on a best efforts basis by
Seller and Buyer. Those credits agreed upon by Buyer and Seller shall be netted
and the final settlement shall be paid as directed in writing by the receiving
party, on final adjustment by the party owing it (the "Final Settlement").

         The Purchase Price shall be adjusted as follows:

         (a) The Purchase Price shall be adjusted upward by the following
         ("Seller's Credits"):

                  (i) an amount equal to the sum of any upward adjustments
         provided elsewhere in this Agreement; and

                  (ii) any other amount agreed upon by any Seller and Buyer in
         writing prior to Closing.

         (b) The Purchase Price shall be adjusted downward by the following
         ("Buyer's Credits"):

                  (i) the total sales value of all Hydrocarbons sold from the
         Assets after the Effective Time and for which Seller is actually paid
         by any third party after the Effective Time, all of which are
         attributable to the Assets, any other monies collected by the Seller
         with respect to the ownership or operation of the Assets after the
         Effective Time for activities which occur after the Effective Time;

                  (ii) the amount of all unpaid ad valorem, property,
         production, excise, severance and similar taxes and assessments (but
         not including income taxes), which taxes and assessments become due and
         payable or accrue to the Assets prior to the Effective Time, which
         amount shall, where possible, be computed based upon the tax rate and
         values 


                                       6
<PAGE>   11

         applicable to the tax period in question; otherwise, the amount of the
         adjustment under this paragraph shall be computed based upon such taxes
         assessed against the applicable portion of the Assets for the
         immediately preceding tax period just ended;

                  (iii) an amount equal to the sum of any downward adjustments
         provided elsewhere in this Agreement;

                  (iv) any other amount agreed upon by any Seller and Buyer in
         writing prior to Closing.

         3.3 PLUGGING, REPLUGGING, ABANDONMENT, REMOVAL, DISPOSAL, AND
RESTORATION. Upon Closing, Buyer shall assume all of Seller's plugging,
replugging, abandonment, removal, disposal and restoration obligations, if any,
associated with the Assets, and the necessary and proper capping and burying of
all associated flow lines. Buyer shall be responsible for the plugging and
abandonment of any wells drilled and the removal of any structures placed on the
Assets, to the extent Seller has any such obligations. All plugging, replugging,
abandonment, removal, disposal, and restoration operations, if any, shall be
conducted in a good and workmanlike manner.

         5.1 BUYER'S REPRESENTATIONS AND WARRANTIES. Buyer represents and
warrants to Seller as of the date hereof and the Closing Date that:

         (a) THE J. T. PHILP COMPANY is a Texas corporation duly organized,
         validly existing, and in good standing and is duly organized to carry
         on business in the state of Texas;

         (b) it has all requisite power and authority to carry on its business
         as presently conducted, to enter into this Agreement and the other

         the terms described in this Agreement, and to perform its other
         obligations under this Agreement and the other documents and agreements
         contemplated hereby. The consummation of the transactions contemplated
         by this Agreement will not violate, nor be in conflict with, any
         provision of Buyer's articles of incorporation, partnership
         agreement(s), by-laws or governing documents, or any material agreement
         or instrument to which Buyer is a party or by which it is bound, or any
         judgment, decree, order, statute, rule or regulation applicable to
         Buyer;

         (c) the execution, delivery and performance of this Agreement and the
         transactions contemplated hereunder have been duly and validly
         authorized by all requisite authorizing action, corporate, partnership
         or otherwise on the part of the Buyer;

         (d) this Agreement, and all documents and instruments required
         hereunder to be executed and delivered by Buyer at Closing, will
         constitute legal, valid and binding obligations of Buyer in accordance
         with their respective terms;

         (e) there are no bankruptcy, reorganization or receivership proceedings
         pending, being contemplated by, or to the actual knowledge of Buyer,
         threatened against Buyer;

         (f) Buyer is an experienced and knowledgeable investor in the oil and
         gas business. Prior to entering into this Agreement, Buyer was advised
         by and has relied solely on its own expertise and legal, tax and other
         professional counsel concerning this Agreement, the Assets and the
         value thereof;

         (g) Buyer is acquiring the Assets for its own account, not with a view
         toward, and for the sale in connection with, any distribution thereof,
         nor with any intention of distributing or selling any interests in the
         Assets in violation of the Securities Act of 1933 or any other
         applicable federal or state securities laws and regulations. In
         entering into this transaction, Buyer has complied with securities laws
         and 


                                       9

         hereunder at Closing, to no more than five additional parties;

         (h) Buyer has arranged, or will arrange, to have available by the
         Closing Date sufficient funds to enable the Buyer to pay in full the
         Purchase Price as herein provided in 3.1 and otherwise to perform its
         obligations under this Agreement; and

         (i) Buyer has arranged to comply with all applicable laws, ordinances,
         rules and regulations in connection with the Assets purchased.

             ARTICLE 6 - ACCESS TO INFORMATION AND INSPECTIONS, AND
                           TITLE/ENVIRONMENTAL DEFECTS

         6.1 TITLE FILES. Promptly after the execution of this Agreement and
until the Closing Date, Seller shall permit Buyer and its representatives at
reasonable times during normal business hours to examine, in Seller's offices at
their actual location, to inspect all Seller's files including but not limited
to abstracts of title, title opinions, title files, ownership maps, lease files,
assignments, division orders, payout statements and agreements pertaining to the
Assets insofar as the same may now be in existence and in the possession of
Seller. No warranty of any kind is made by Seller as to the information so
supplied, and Buyer agrees that any conclusions drawn therefrom are the result
of its own independent review and judgment.

         6.2 OTHER FILES. Prior to the execution of this Agreement, Seller has
made available to Buyer, for its inspection, certain records and data in
possession of Seller, or its agents, which are directly related to or constitute
a portion of the Assets, and certain other files, records, and data pertaining
to the Assets. The Data furnished by Seller is believed by Seller to be accurate
and representative. No warranty of any kind is made by Seller as to the
information so supplied, and Buyer agrees that any conclusions drawn therefrom
are the result of its own independent review and judgment.

         6.3 CONFIDENTIALITY AGREEMENT. All such information made available to
Buyer shall be maintained confidential by Buyer until Closing. Any
confidentiality agreement Buyer has previously executed with Seller with respect
to the Assets shall continue in force until Closing, at which time such
agreement shall terminate. Buyer shall further take whatever reasonable steps
which may be necessary to ensure that Buyer's employees, consultants and agents
comply with the provisions of this Section 6.3.



                                       10
<PAGE>   15

         6.4 INSPECTIONS. By the execution of this Agreement, Seller grants its
permission to Buyer and its representatives, at reasonable times and at their
sole risk, cost and expense, to conduct reasonable inspections of the Assets;
provided, however, Buyer shall repair any damage to the Assets resulting from
such inspections and Buyer does hereby indemnify and hold harmless Seller from
and against any and all losses, costs, damages, obligations, claims,
liabilities, expenses (including court costs and attorney's fees), or causes of
action arising from Buyer's inspection and observation of the Assets, including,
without limitation, claims for personal injuries or death of employees of the
Buyer, its contractors, agents, consultants and representatives, and property
damages.

         6.5 TITLE AND ENVIRONMENTAL DEFECTS - NOTICE, ADJUSTMENTS AND
TERMINATION. Upon execution of and pursuant to the terms of this Agreement,
Buyer shall have the right to conduct its investigation into the status of the
title of the Assets and the physical and environmental condition of the Assets.
Such investigation or inspection shall be reasonable and shall be conducted at
such time and in such manner as is mutually agreed to by the Parties. If, in the
course of conducting such investigation, Buyer discovers significant
environmental matters or title defects materially affecting the value of Assets,
in Buyer's sole discretion, Buyer may, no later than ten days prior to the
Closing Date, notify Seller in writing specifying such defects, the Assets
affected thereby and Buyer's estimate of (i) in the case of non-producing net
acreage, as described on the schedule of non-producing net acreage attached
hereto as Exhibit "D", the net reduction in acreage covered by such defects,
and/or (ii) in the case of producing acreage, as described on the schedule of
substantial producing acreage attached hereto as Exhibit "E", the net reduction
in value of the producing acreage covered by such defects. Material defects are
defined as those which collectively exceed (i) 10% of the net non-producing
acreage, or (ii) 5% of the allocated value of the substantial producing acreage.
Buyer acknowledges that Seller produced Exhibit "E" as a matter of convenience
for Buyer, and Buyer shall satisfy itself as to the accuracy of the information
contained therein.

         If Buyer fails to notify Seller no later than ten days prior to Closing
of the defects, the defects will be deemed waived, the Parties shall proceed
with Closing, Seller shall be under no obligation to correct the defects and
Buyer shall assume the risks related to the Assets. If Buyer notifies Seller of
the defects no later than ten days before Closing and if such defects are, in
the opinion of Seller, capable of being corrected prior to the Closing Date,
Seller may, but shall be under no obligation to, correct at its own costs and
expense, such defects on or before the Closing Date.



                                       11
<PAGE>   16

         If Seller, in Buyer's sole discretion, fails to correct the defects
prior to Closing, and Buyer's estimate of such defects collectively exceed ten
percent (10%) of the net non-producing acreage, or 5 percent (5%) of the value
of the substantial producing acreage, which calculation Buyer shall supply to
Seller at the time of notification of any such defects, Buyer shall have the
right to terminate this Agreement by so notifying Seller in writing. Upon such
termination, Seller shall return the Performance Deposit to Buyer within ten
(10) days of receipt of the notice of termination and neither Party shall have
any further obligations hereunder. Otherwise, Closing shall occur and Seller
shall make a reasonable effort to correct the defects within ninety (90) days of
Closing. If Seller, in Buyer's sole discretion, fails to correct the defects
within such ninety (90) day period, Seller shall refund to Buyer a defect value
amount that is mutually agreed to by the Parties and Buyer shall transfer that
part of the Assets affected thereby to Seller. In the event that the Parties
cannot mutually agree upon the defect value amount, the decision shall be
submitted to binding arbitration under the rules of the American Arbitration
Association.

                       ARTICLE 7 - TITLE AND OTHER MATTERS

         7.1 NO WARRANTY OR REPRESENTATION. SELLER SHALL CONVEY SELLER'S
INTERESTS IN AND TO THE ASSETS TO BUYER SUBJECT TO ALL ROYALTIES, OVERRIDING
ROYALTIES, BURDENS, AND ENCUMBRANCES, AND WITHOUT ANY WARRANTY OF TITLE, EXPRESS
OR IMPLIED, AS PROVIDED IN THE FORM OF ASSIGNMENT, BILL OF SALE AND CONVEYANCE
ATTACHED AS EXHIBIT "B" HERETO. SELLER MAKES NO WARRANTY OR REPRESENTATION,
EXPRESS OR IMPLIED, WITH RESPECT TO THE ACCURACY, COMPLETENESS, OR MATERIALITY
OF THE INFORMATION, RECORDS, AND DATA NOW, HERETOFORE, OR HEREAFTER MADE
AVAILABLE TO BUYER IN CONNECTION WITH THE ASSETS OR THIS AGREEMENT (INCLUDING,
WITHOUT LIMITATION, ANY DESCRIPTION OF THE ASSETS, QUALITY OR QUANTITY OR
HYDROCARBON RESERVES, IF ANY, PRODUCTION RATES, RECOMPLETION OPPORTUNITIES,
DECLINE RATES, GAS BALANCING INFORMATION, POTENTIAL FOR PRODUCTION OF
HYDROCARBONS FROM THE ASSETS, OR ANY OTHER MATTERS CONTAINED IN ANY OTHER
MATERIAL FURNISHED TO BUYER BY SELLER OR BY SELLER'S AGENTS OR REPRESENTATIVES).
ANY AND ALL SUCH DATA, INFORMATION AND MATERIAL FURNISHED BY SELLER IS PROVIDED
AS A CONVENIENCE ONLY AND ANY RELIANCE ON OR USE OF SAME IS AT BUYER'S SOLE
RISK.

         7.2 BUYER'S TITLE REVIEW. Buyer specifically assumes the risk of
description and title to the Assets. In addition, Buyer acknowledges that prior
to Closing it will have reviewed the title material in Seller's possession and
made available to Buyer and examined the status of title of the Assets to be
assigned. Buyer acknowledges that it will have conducted all necessary due
diligence with respect to title matters; and will have satisfied itself with the
status of Seller's title and agrees if this 


                                       12
<PAGE>   17

         transaction closes, to accept same AS IS, WHERE IS and without any
         title warranties, express or implied.

         manage, and administer the Assets in a good and workmanlike manner
         consistent with its past principles and shall carry on its business
         with respect to the Assets in substantially the same manner as before
         execution of this Agreement. Seller shall: (1) from and after the date
         of execution of this Agreement until Closing, not be entitled to
         continue to grant, extend, ratify, or amend, as it deems necessary, oil
         and gas leases on the Assets in the normal course of its business
         without the express written consent of Buyer; (2) consult with, inform,
         and advise Buyer regarding all material matters concerning the
         operations, management, and administration of the Assets; (3) obtain

         joint venture, partnership, or similar agreement; and (4) not approve

         8.1(a), Buyer shall respond in writing within five (5) days to Seller's
         request for approval and failure of Buyer to respond to Seller's
         request for approval within such time shall release Seller from the
         obligation to obtain Buyer's approval before proceeding on such matter.

         (b) Seller shall promptly notify Buyer of any suit, demand, action, or
         other proceeding received by Seller after this Agreement is executed
         before any court, arbitrator, or governmental agency and any cause of
         action filed after the Effective Time which relates to the Assets or
         which might result in impairment or loss of Seller's interest in any
         portion of the Assets or which might hinder or impede the operation of
         the Assets.

         8.2 LIMITATIONS ON SELLER'S COVENANTS PENDING CLOSING. To the extent
Seller is not the operator of any of the Assets, the obligations of Seller in
Section 8.1 above, which have reference to operations or activities which
normally or pursuant to existing contracts are carried out or performed by the
operator, shall be construed to require only that Seller use all reasonable
efforts (without being obligated to incur any expense or institute any cause of
action) to cause the operator of such Assets to take such actions or render such
performance within the constraints of the applicable operating agreements and
other applicable agreements.

         15.3 BROKER OR FINDER'S FEE. Each party hereby agrees to indemnify and
hold the other harmless from and against any claim for a brokerage or finder's
fee or commission in connection with this Agreement or the transactions
contemplated by this Agreement to the extent such claim arises from or is
attributable to the actions of such indemnifying party, including, without

warranty, such party shall have the right, but not the obligation, to
participate fully in the defense of any such claim. Reasonable attorneys' fees,
court costs, interest, penalties, and other expenses incurred in connection with
the defense of such claims shall be included in Seller's and Buyer's indemnities

announcement or statement to be made by both of such Parties; or (ii) obtain
written approval of the other party hereto to the text of a public announcement
or statement to be made solely by Seller or Buyer, as the case may be. Nothing
contained in this paragraph shall be construed to require either party to obtain
approval of the other party hereto to disclose information with respect to the
transaction contemplated by this Agreement to any state or federal governmental
authority or agency to the extent (i) required by applicable law or by any
applicable rules, regulations or orders of 


                                       20

Buyer shall advise Seller of the pertinent recording data. Seller shall not be
responsible for any loss to Buyer because of Buyer's failure to file or record
documents correctly or promptly.

         16.3 FURTHER ASSURANCES AND RECORDS.

         (a) After the Closing each of the Parties will execute, acknowledge and
         deliver to the other such further instruments, and take such other
         action, as may be reasonably requested in order to more effectively
         assure to said party all of the respective properties, rights, titles,
         interests, estates, and privileges intended to be assigned, delivered
         or inuring to the benefit of such party in consummation of the

         (b) Buyer agrees to maintain the files and records of Seller that are
         acquired pursuant to this Agreement until August 1, 2000. In addition
         to any other audit rights granted hereunder, Buyer shall provide Seller
         and its representatives reasonable access to and the right to copy such
         files and records, at the Seller's cost, for the purposes of (i)
         preparing and delivering any accounting provided for under this
         Agreement and adjusting, prorating and settling the charges and credits
         provided for in this Agreement; (ii) complying with any law, rule or
         regulations affecting Seller's interest in the Assets prior to the
         Closing Date; (iii) preparing any audit of the books and records of any
         third party relating to Seller's interest in the Assets prior to the
         Closing Date, or responding to any audit prepared by such third

         tax audit; or (vi) asserting, defending or otherwise dealing with any
         claim or dispute under this Agreement.

         (c) To the extent not obtained or satisfied as of Closing, Seller
         agrees to continue to use all reasonable efforts, but without any
         obligation to incur any cost or expense in connection therewith, and to
         cooperate with Buyer's efforts to

Howell Petroleum Corporation

Houston, Texas  77002-6923

Attention:  Richard K. Hebert, President and COO

Re:      Amendment to Purchase and Sale Agreement between Howell Petroleum
         Corporation ("Seller") and the J.T. Philip Company ("Buyer"), effective
         November 1, 1998 ("Agreement")

Gentlemen:

Buyer and Seller do hereby amend the Agreement in the manner set forth below.
All terms defined in the Agreement shall have the same meaning when used herein:

Section 11.3 of the Agreement is hereby deleted and the following provision
substituted therefor:

         11.3 Net Profits Interest. From and after the date at which aggregate
         Net Revenue equals $13,000,000 (hereinafter called "Payout"), Buyer
         shall pay, within 30 days following the end of each calendar quarter,
         to Seller 10% of all Net Profits (defined below) received by Buyer
         after Payout. The term "Net Profits" as used in this Agreement shall
         mean the Net Revenue received by Buyer after Payout during the subject
         calendar quarter. The definition of Net Revenue as defined in Section
         1.13 shall not include (i) general and administrative expenses incurred
         by Buyer (excluding bona fide third party expenses) directly associated
         with the ownership of the Assets, or (ii) costs or revenue associated
         with participation in a working interest. Buyer also agrees that leases
         to affiliates, if made will be at then current competitive lease rates.
         The net profits interest created hereby does not encumber the Assets or
         "run with the land," and Buyer shall have the authority and ability to
         transfer (via arm's-length transaction with a bona fide third party)
         all or any portion of the Assets free of this net profits interest;
         however, any proceeds received by Buyer from any such disposition
         (including any retained interest) shall be treated as income
         attributable to the Assets for the purpose of computing Net Revenue.
         Prior to Payout, Buyer shall provide an annual statement to Seller
         indicating Net Revenue which shall detail actual receipts and expenses
         attributable to Assets from all sources for the calendar year. After
         Payout, Buyer shall provide quarterly statements which shall detail
         receipts and expenses. Seller shall have


<PAGE>   31



         the rights to audit all such statements and Buyer's records relating
         thereto, with advance notice, during regular business hours and at
         Seller's sole cost and expense.

The first sentence of Section 3.1 of the Agreement is hereby amended by
inserting the words net profits interest therein, so that this sentence now
reads as follows:

         Subject to adjustments as set forth in 3.1, the Purchase Price for the
         Assets shall be thirteen million dollars ($13,000,000.00), and the Net
         Profits Interest described in Section 11.3 below. [remainder unchanged]

The third sentence of Section 6.5 of this Agreement is hereby amended by
inserting the words gas imbalances therein, so that this sentence now reads as
follows:

         If, in the course of conducting such investigation, Buyer discovers
         significant environmental matters, title defects, or gas imbalances
         materially affecting the value of Assets.... [remainder unchanged]

Buyer shall have until 10:00 a.m. Dallas, Texas time on Monday, November 16,
1998, to initiate the wire transfer of funds required by Section 2.2 of the
Agreement.

Except as amended hereby, the Agreement remains in full force and effect in
accordance with its terms.

         SECTION 6.2 Corporate and Governmental Authorization; Contravention.

purporting to execute the same of this Agreement or the other Loan Papers are
within such Person's power, have been duly authorized by all necessary action,
require no action by or in respect of, or filing with, any governmental body,
agency or official (except that the perfection of Liens created by certain of
the Security Documents may require the filing of financing statements, mortgages
or similar instruments in the appropriate recordation offices), and do not
contravene, or constitute a default under, any provision of applicable law or
regulation (including, without limitation, the Margin Regulations) or any
agreement creating or governing such Person or any agreement, judgment,
injunction, order, decree or other instrument binding upon such Person or result
in the creation or imposition of any Lien on any Property of the Borrower,
except Liens securing the Obligations.

         SECTION 6.3 Binding Effect. (a) This Agreement constitutes a valid and
binding agreement of the Borrower; the Note, when executed and delivered in
accordance with this Agreement, will constitute the valid and binding obligation
of the Borrower; the Security Documents, when executed and delivered in
accordance with this Agreement, will constitute valid and binding obligations of
each Person purporting to execute the same;

         (b) Each Loan Paper is enforceable in accordance with its terms except
as (i) the enforceability thereof may be limited by bankruptcy, insolvency or
similar laws affecting creditors, rights generally and (ii) rights of

fact. All information heretofore furnished by the Borrower to the Lender for
purposes of or in connection with this Agreement or any transaction contemplated
hereby is, and all such information hereafter furnished by the Borrower to the
Lender will be, true and accurate in every material respect or based on
reasonable estimates on the date as of which such information is stated or
certified. The Borrower has disclosed to the Lender in writing any and all facts

         (a) The Borrower is a newly formed Delaware corporation and has no
material liabilities, direct or contingent.

         SECTION 6.7 Litigation. There is no action, suit or proceeding pending
against, or to the knowledge of the Borrower threatened against or affecting the
Borrower before any Tribunal or arbitrator in which there is a reasonable
possibility of an adverse decision which could materially and adversely affect

any other Loan Papers.

         SECTION 6.8 Plans.   The Borrower has no Plans.

         SECTION 6.9 Taxes and Filing of Tax Returns. The Borrower has filed or

such returns, including interest and penalties, and all other Taxes which are
payable by it, to the extent the same have become due and payable (unless, with
respect to such other Taxes, the criteria set forth in Section 7.5 are being

of Interests. (a) The Borrower has good and indefeasible title to all Collateral

or violation of the requirements of any Environmental Law or (B) the release or
threatened release of any toxic or hazardous waste, substance or constituent, or
other substance into the environment, or (ii) received notice or otherwise
learned of any federal or state investigation evaluating whether any remedial
action is needed to respond to a release or threatened release of any toxic or
hazardous waste, substance or constituent into the environment for which the
Borrower is or may be liable which would individually or in the aggregate have a
Material Adverse Effect.

         (c) The Borrower is not acquiring and does not own any "working
interests" in oil and gas properties and, thus, is not and will not be obligated
to pay drilling expenses for wells drilled on its Property or to bear any costs
of operations of any wells now or hereafter on its Property.

         SECTION 6.11 Business; Compliance. The Borrower has performed and
abided by all obligations required to be performed by it to the extent it could
be materially and adversely affected under any license, permit, order,
authorization, grant, contract, agreement, or regulation to which it is a party
or by which it or any of its Property is bound.

         SECTION 6.12 Licenses, Permits, Etc. The Borrower possesses such valid

as are necessary to carry on its business as now being conducted and to own its
properties.

         SECTION 6.13 Compliance with Law. The business and operations of the

Borrower is not a "holding company," or a "subsidiary company" of a "holding

of a "holding company," as such terms are defined in the Public Utility Holding
Company Act of 1935, as amended.



                                       19
<PAGE>   24

         (b) The Borrower is not defined as a "utility" under the laws of the
State of Texas or any other jurisdiction wherein the Borrower is required to
qualify to do business.

         SECTION 6.17. Year 2000 Preparedness. The Borrower has (i) initiated a
review and assessment of all areas within its business and operations (including
those affected by suppliers, vendors and customers) that could be adversely
affected by the "Year 2000 Problem" (that is, the risk that computer
applications used by the Borrower (or its suppliers, vendors and customers) may
be unable to recognize and perform properly date-sensitive functions involving
certain dates prior to and any date after December 31, 1999), (ii) developed a
plan and timeline for addressing the Year 2000 Problem on a timely basis, and
(iii) to date, implemented that plan in accordance with that timetable. Based on
the foregoing, the Borrower believes that all computer applications (including
those of its suppliers, vendors and customers) that are material to its business
and operations are reasonably expected on a timely basis to be able to perform
properly date-sensitive functions for all dates before and after January 1, 2000
(that is, be "Year 2000 compliant"), except to the extent that a failure to do
so could not reasonably be expected to have Material Adverse Effect.

         SECTION 6.18 Refunds; Certain Contracts. (a) No orders of, proceedings
pending before, or other requirements of, the Federal Energy Regulatory
Commission, the Texas Railroad Commission, or any Governmental Authority exist
which could result in the Borrower being required to refund any material portion
of the proceeds received or to be received from the sale of hydrocarbons
constituting part of the Collateral.

         (b) The Borrower (i) is not obligated in any material respect by virtue
of any prepayment made under any contract containing a "take-or-pay" or
"prepayment" provision or under any similar agreement to deliver hydrocarbons
produced from or allocated to any of the Collateral at some future date without
receiving full payment therefor within 90 days of delivery, and (ii) has not
produced gas, in any material amount, subject to, and neither the Borrower nor
any of the Collateral is subject to, balancing rights of third parties or
subject to balancing duties under governmental requirements.

         SECTION 6.19 No Default. No Default has occurred which is continuing as
of the Closing Date.

                                   ARTICLE VII

                                    COVENANTS

unpaid, the Borrower will duly perform and observe each and all of the covenants
and agreements hereinafter set forth:

         SECTION 7.1 Use of Proceeds. (a) The Borrower will use the proceeds of
the Loan solely to finance the acquisition of mineral and royalty interests.

<PAGE>   25
         (b) The Borrower will not, directly or indirectly, use any of the
proceeds of the Loan for the purpose of purchasing or carrying any "margin
stock" within the meaning of Regulation U of the Board of Governors of the
Federal Reserve System (12 C.F.R. 221, as amended), or any "security that is
publicly-held" within the meaning of Regulation T of such Board of Governors (12
C.F.R. 220, as amended), or otherwise take or permit any action which would
involve a violation of such Regulation U, Regulation T or Regulation X (12
C.F.R. 224, as amended) or any other regulation of such Board of Governors. The
Loan is not secured, directly or indirectly, in whole or in part, by collateral
that includes any "margin stock" within the meaning of Regulation U. The
Borrower will not engage principally, or as one of its important activities, in
the business of extending credit for the purpose of purchasing or carrying any
"margin stock" within the meaning of such Regulation U.

having only salvage value. Any consent by the Lender to the sale of Collateral

Base be determined under Section 2.7(a) and that the proceeds of such sale plus
such additional amounts as the Lender deems necessary to avoid the occurrence of
a Borrowing Base Deficiency be applied to the Obligations. In this connection,

12-month period of Property of the Borrower, in the aggregate, having Collateral
Value of up to 20% of all Property of the Borrower having Collateral Value.

                                   ARTICLE IX

                                  MISCELLANEOUS

         SECTION 9.1 Amendments and Waivers. (a) Any term, covenant, agreement
or condition of this Agreement or any other Loan Paper may be amended, or
compliance therewith may be waived (either generally or in a particular instance
and either retroactively or prospectively) by a written instrument signed by the
Borrower and the Lender.

         (b) No failure or delay by the Lender in exercising any right, power or
privilege under this Agreement or any other Loan Paper shall operate as a waiver
thereof nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The rights and remedies herein provided shall be cumulative and not exclusive of
any rights or remedies provided by law or in equity or in any of the other Loan
Papers.

         SECTION 9.2 Highest Lawful Interest Rate. Regardless of any provision
contained in any of the Loan Papers, the Lender shall never be entitled to
receive, collect, or apply as interest on all or any part of the Loan, any
amount in excess of the Highest Lawful Rate in effect from day to day, and, in
the event the Lender ever receives, collects, or applies as interest any such
excess, such amount which would be deemed excessive interest shall be deemed a
partial prepayment of the principal of the Loan and treated hereunder as such;
and, if the entire principal amount of the Loan owed to the Lender is paid in
full, any remaining excess shall be repaid to the Borrower. In determining
whether the interest paid or payable, under any specific contingency, exceeds
the Highest Lawful Rate in effect from day to day, the Borrower and the Lender
shall, to the maximum extent permitted under applicable law, (i) characterize
any nonprincipal payment as an expense, fee, or premium rather than as interest,
(ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize,
prorate, allocate, and spread the total amount of interest throughout the entire
contemplated term of the Loan so that the interest rate is uniform throughout
the entire term of the Loan; provided that, if the interest received by the
Lender for the actual period of existence thereof exceeds the Highest Lawful
Rate in effect from day to day, the Lender shall apply or refund to the Borrower
the amount of such excess as provided in this Section, and, in such event, the
Lender shall not be subject to any penalties provided by any laws for
contracting for, charging, taking, reserving, or receiving interest in excess of
the Highest Lawful Rate in effect from day to day.

         SECTION 9.3 INDEMNITY. (A) WHETHER OR NOT ANY LOAN IS EVER FUNDED, THE
BORROWER AGREES TO INDEMNIFY AND DEFEND AND HOLD HARMLESS ON A CURRENT BASIS THE
LENDER AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS AND ATTORNEYS, AND EACH OF
THEM (THE "INDEMNIFIED PARTIES"), FROM AND AGAINST ANY AND ALL LIABILITIES,
LOSSES, DAMAGES, COSTS, INTEREST, CHARGES, COUNSEL FEES AND OTHER EXPENSES AND
PENALTIES OF ANY KIND WHICH ANY OF THE INDEMNIFIED PARTIES MAY SUSTAIN OR INCUR
IN CONNECTION WITH ANY INVESTIGATIVE,

EXECUTION AND DELIVERY OF THIS AGREEMENT OR ANY OF THE OTHER LOAN PAPERS AND/OR
THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH
INDEMNIFIED PARTY SHALL BE INDEMNIFIED UNDER THIS SECTION WITHOUT REGARD TO THE
CAUSE OR THE NEGLIGENCE OF ANY INDEMNIFIED PARTY, WHETHER SUCH NEGLIGENCE BE THE
SOLE NEGLIGENCE, COMPARATIVE NEGLIGENCE OR CONCURRENT NEGLIGENCE OF ANY
INDEMNIFIED PARTY.

         (b) Any amount to be paid under this Section to the Lender shall be a
demand obligation owing by the Borrower and if not-paid within ten days of
demand shall bear interest from the date of expenditure by the Lender until paid
at a per annum rate equal to the lesser of (i) the Default Rate or (ii) the
Highest Lawful Rate. The obligations of the Borrower under this Section shall
survive payment of the Note and the assignment of any right hereunder.

         SECTION 9.4 Expenses. (a) Whether or not the Loan is ever funded, the
Borrower shall pay (i) all out-of-pocket expenses of the Lender, including,
without limitation, fees and disbursements of counsel for the Lender in
connection with the preparation of this Agreement and the other Loan Papers
(including, without limitation, the furnishing of any written or oral opinions
or advice incident to this transaction) and, if appropriate, the recordation of
the Loan Papers, any waiver or consent hereunder or any amendment hereof or any
Default or alleged Default hereunder, and (ii) if an Event of Default occurs,
all out-of-pocket expenses incurred by the Lender, including, without
limitation, fees and disbursements of counsel in connection with such Event of
Default and collection and other enforcement proceedings resulting therefrom,
fees of auditors, consultants, engineers and other Persons incurred in
connection therewith (including, without limitation, the supervision,
maintenance or disposition of the Collateral) and investigative expenses
incurred by the Lender in connection therewith, which amounts shall be deemed
compensatory in nature and liquidated as to amount upon notice to the Borrower
by the Lender and which amounts shall include, but not be limited to (A) all
court costs, (B) reasonable attorneys' fees, (C) reasonable fees and expenses of
auditors and accountants incurred to protect the interests of the Lender, (D)
fees and expenses incurred in connection with the participation by the Lender as
a member of the creditors' committee in a case commenced under any Insolvency
Proceeding, (E) fees and expenses incurred in connection with lifting the
automatic stay prescribed in Section 362 Title 11 of the United States Code, and
(F) fees and expenses incurred in connection with any action pursuant to Section
1129 Title 11 of the United States Code all reasonably incurred by the Lender in
connection with the collection of any sums due under the Loan Papers, together
with interest at the per annum interest rate equal to the Default Rate,
calculated on a basis of a calendar year of 365 or 366 days, as the case may be,
counting the actual number of days elapsed, on each such amount from the date of
notification that the same was expended, advanced, or incurred by the Lender
until the date it is repaid to the Lender, with the obligations under this
Section surviving the non-assumption of this Agreement in a case commenced under
any Insolvency Proceeding and being binding upon the Borrower and/or a trustee,
receiver, custodian, or liquidator of the Borrower appointed in any such case.

         (b) THE BORROWER SHALL INDEMNIFY THE LENDER AGAINST ANY TRANSFER TAXES,
DOCUMENTARY TAXES, ASSESSMENTS OR CHARGES MADE BY ANY GOVERNMENTAL AUTHORITY BY
REASON OF THE EXECUTION AND DELIVERY OF THIS AGREEMENT OR THE OTHER LOAN PAPERS.

         (c) Any amount to be paid under this Section to the Lender shall be a
demand obligation owing by the Borrower and if not paid within ten days of
demand shall bear interest from the date of expenditure by the Lender until paid
at a per annum rate equal to the lessor of the Default Rate or the Highest
Lawful Rate. The obligations of the Borrower under this Section shall survive
payment of the Note and the assignment of any right hereunder.

         SECTION 9.5 Taxes. The Borrower will, to the extent they may lawfully
do so, pay all Taxes (including interest and penalties but expressly excluding
federal or state income taxes) which may be payable in respect of the execution
and delivery of this Agreement or the other Loan Papers, or in respect of any
amendment of or waiver under or with respect to the foregoing, and will save the
Lender harmless against any loss or liability resulting from nonpayment or delay
in payment of any such Taxes (as limited above). The obligations of the Borrower
under this Section shall survive the payment of the Note and the assignment of
any right hereunder.

         SECTION 9.6 Notices. Except as specifically provided otherwise herein,
all notices, requests and other communications to any party hereunder shall be
in writing (including by telecopy or similar writing) and shall be given to such
party at its address and to the attention of the Person set forth on the
signature pages hereof (or in the case of notices to the Borrower, to the
attention of any officer, or other Person holding a similar position, of the
Borrower) or such other address or telecopy number or Person as such party may
hereafter specify for such purpose by notice to the other party. Each such
notice, request or other communication shall be effective (i) if given by
telecopy, when such telecopy is transmitted to the telecopier number specified
in this Section and the receipt thereof is acknowledged, (ii) if given by mail,
72 hours after such communication is deposited in the mails (certified, return
receipt requested) addressed as aforesaid or (iii) if given by any other means,
when delivered at the address specified in this Section or otherwise delivered
to the Borrower, provided that notice to the Lender under Section 2.2 shall not
be effective until received, and provided further that, oral notices to the
Borrower of decreases in the Borrowing Base shall be effective when communicated
to the Borrower.

         SECTION 9.7 Right of Set-Offs. (a) Upon the occurrence and during the
continuance of any Event of Default, the Lender is hereby authorized at any time
and from time to time, to the fullest extent permitted by law, to set off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other indebtedness at any time owing by the Lender
to or for the credit or the account of the Borrower against the obligations of
the Borrower to the Lender, irrespective of whether or not the Lender shall have
made any demand under this Agreement or any other Loan Paper and although such
obligations may be unmatured. The Lender agrees promptly to notify the Borrower
after any such set-off and application made by the Lender, provided that the
failure to give such notice shall not affect the validity of such set-off and
application. The rights of 


                                       34
<PAGE>   39

the Lender under this Section are in addition to other rights and remedies
(including, without limitation, other rights of set-off) which the Lender may
have.

         (b) The Borrower agrees, to the fullest extent it may effectively do so
under applicable law, that any holder of a participation in the Loan may
exercise rights of set-off or counterclaim and other rights with respect to such
participation as fully as if such holder of a participation were a direct
creditor of the Borrower in the amount of such participation.

         SECTION 9.8 Survival. All representations, warranties and covenants
made by or on behalf of the Borrower in this Agreement or the other Loan Papers
herein or in any certificate or other instrument delivered by it or in its
behalf under the Loan Papers shall be considered to have been relied upon by the
Lender and shall survive the delivery to the Lender of such Loan Papers or the
extension of the Loan (or any part thereof), regardless of any investigation
made by or on behalf of the Lender.

         SECTION 9.9 Successors and Assigns: Rights of Other Holders. (a) This
Agreement shall be binding on the parties hereto and their respective successors
and inure to the benefit of and be enforceable by the Lender, its legal
representatives, successors and assigns. With respect to the Borrower, this
Agreement and the other Loan Papers and the rights of the Borrower hereunder and
thereunder shall not be assignable in any respect.

         (b) The Lender may at any time sell, transfer, assign, or grant
participations in the Obligations or any portion thereof; and the Lender may
forward to each Transferee and prospective Transferee all documents and
information relating to such Obligations, whether furnished by the Borrower or
otherwise obtained, as the Lender determines necessary or desirable. The
Borrower agrees that each Transferee, regardless of the nature of any transfer
to it, may exercise all rights (including, without limitation, rights of
set-off) with respect to the portion of the Obligations held by it as fully as
if such Transferee were the direct holder thereof, subject to any agreements
