to herein as a "Party", and collectively as the "Parties".

                                  WITNESSETH:

         WHEREAS, MAII acquired CRD from GENI pursuant to an Agreement and Plan
of Merger, dated as of August 16, 2001, by and among MAII, GENI and CRD (the
"Merger Agreement"); and

         WHEREAS, GENI currently owns 752,000 shares of the common stock, par

common stock of MAII currently in MAII's possession; and

         WHEREAS, MAII and GENI desire to redefine their business relationship
to the extent provided herein;

         NOW, THEREFORE, in consideration of the foregoing and for other good
and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto hereby agree as follows:

         1. Purchase of Stock. On the date hereof, MAII hereby agrees to
purchase from GENI, and GENI hereby agrees to sell to MAII, the Shares, at an

deliver a Bill of Sale and Assignment Agreement, in substantially the form of
Exhibit A attached hereto, and CRD hereby agrees to cause the Acquisition to
close (the "Assignment Agreement").

covenants and agreements contained in the Merger Agreement, MAII has made
certain claims against GENI for breaches of certain representations, warranties,
covenants and agreements and claims under certain indemnification side letters,
which claims are described in Exhibit B attached hereto (the "Claims"). The
Parties hereto agree to settle the Claims by a payment by GENI to MAII of

substantially in the form of Exhibit C attached hereto. In addition,

$800,000 shall be payable by wire transfer to GENI (the "GENI Wire"); and (ii)
the remaining $185,000 shall be payable to Steven Oh pursuant to the Assignment
Agreement. The GENI Wire shall be to GENI's brokerage account which holds the
Shares, instructions for which shall be delivered in writing by GENI to MAII.
Upon GENI's confirmation that the GENI Wire has been wired into GENI's account,
GENI shall immediately cause the Shares to be transferred by GENI to MAII
through the Depository Trust Company to MAII's account at Merrill Lynch, Pierce,
Fenner & Smith, Inc., DTC No 5198, for Acct. No. 542-07J81. Immediately after
receiving notification that MAII has received the Shares in its account at
Merrill Lynch, MAII shall send written confirmation of the receipt of the Shares
to GENI. GENI agrees not to withdraw, transfer, spend or otherwise dissipate the
Wired Payment funds until GENI has received written confirmation from MAII or

and HIBERNIA NATIONAL BANK, a national banking association ("Lender"), who

                                   ARTICLE 1

                                 GENERAL TERMS

                  Section 1.1 Terms Defined Above. As used in this Agreement,

                  Section 1.2 Certain Definitions. As used in this Agreement,

Section 9.14), unless the context otherwise requires:

                  "Advances" shall mean the borrowings on the Closing Date
                  under the Loan and all or any portion of such borrowings and
                  other or subsequent reborrowings under the Loan so long as
                  same remain outstanding and unpaid.

                  "Amount" shall mean five million ($5,000,000.00) dollars.

                  "Base Rate" shall mean, for any day, an interest rate per
                  annum equal to the Prime Rate in effect on such day plus the
                  Applicable Prime Rate Margin (as defined below). The
                  "Applicable Prime Rate Margin" shall mean the following per
                  annum interest rate from time to time, determined for each
                  fiscal quarter by reference to the Percentage Outstanding for

                  following schedule:

                                                              Applicable Prime
                  Percentage Outstanding                         Rate Margin

                  above 2/3                                            0.25%

                  The Applicable Prime Rate Margin shall remain fixed during

<PAGE>

                  quarter of this Agreement, commencing July 1, 2001, the
                  Applicable Prime Rate Margin shall be zero (0%). Without
                  notice to the Borrower, the Base Rate shall change
                  automatically from time to time as and in the amount by which
                  the Prime Rate shall fluctuate, with each such change in the
                  Base Rate to be effective as of the date of each change in
                  the Prime Rate, adjusted daily.

                  "Borrowing Base" shall mean, at any time, the dollar amount
                  calculated as the maximum loan value of the Collateral as
                  determined by the Lender in its sole discretion, but based
                  upon the Lender's customary standards and practices from time
                  to time in effect with respect to secured oil and gas
                  property lines of credit. The Borrowing Base shall be subject
                  to automatic Monthly Borrowing Base Reductions as provided in
                  Subsection 2.4(c). Any good faith determination by the Lender
                  of the Borrowing Base shall be final and conclusive. The
                  Borrowing Base may be revised by Lender at any time to
                  reflect changes in the Collateral or the occurrence of events
                  or economic conditions or otherwise pursuant to Lender's
                  customary standards and practices as such exist at that
                  particular time, and further will be subject to scheduled
                  semi-annual re-determinations during the term of this Loan.
                  Additionally, the Borrower may request once per year
                  (commencing 90 days after the Closing Date) that an
                  unscheduled redetermination be done by Lender. The Lender
                  shall notify the Borrower of the result of each Borrowing
                  Base redetermination by the Lender. Each determination of the
                  Monthly Borrowing Base Reductions, and of the Borrowing Base
                  (subject to such monthly Borrowing Base Reductions), shall be
                  effective until redetermined by the Lender in accordance with
                  this Agreement. Such redetermination by the Lender may lead
                  to increased or decreased credit availability to the Borrower
                  under the revised Borrowing Base schedule. Without limiting
                  the foregoing, the Lender may exclude, in its sole and
                  absolute discretion, any property or portion of production
                  therefrom from the Borrowing Base, at any time, because title
                  information on, or the status of title to, such property is
                  not reasonably satisfactory to Lender, such property is not
                  Collateral, the Lender's Lien therein is not first and prior
                  to all others, such property is subject to contractual
                  agreements or commitments not reasonably satisfactory to
                  Lender, or such property is not assignable. On the Closing
                  Date, the Borrowing Base is $2,500,000.00.

                  Governors of the Federal Reserve System) with a maturity
                  equal to such Interest Period. In determining this
                  percentage, the Lender may use any reasonable averaging and
                  attribution method. "Interest Period" shall mean the period
                  between the Business Day on which the LIBO Rate shall begin

                  day of any Interest Period would otherwise occur on a day
                  other than a Business Day, the last day of such Interest
                  Period shall be extended to occur on the next succeeding
                  Business Day, except that if the next succeeding Business Day
                  would occur in the next following calendar month, the last
                  day of such Interest Period shall be shortened to occur on
                  the next preceding Business Day; (iii) whenever the first day
                  of any Interest Period occurs on a day of an initial calendar
                  month for which there is no numerically corresponding day in
                  the calendar month that succeeds such initial calendar month
                  by the number of months in such Interest Period, such
                  Interest Period shall end on the last Business Day of such
                  succeeding calendar month; and (iv) if the Borrower fails to
                  designate an Interest Period, the Interest Period for a LIBO
                  Rate Advance (recognizing that under Subsection 2.1(b) below
                  the Lender is not obligated to make such a LIBO Rate Advance
                  in the absence of such designation by the Borrower) shall be
                  deemed to be one month until a different designation is made
                  for a subsequent Interest Period. No Interest Period for a
                  LIBO Rate Advance shall have a duration of less than one
                  month, and if any such Interest Period would otherwise be a
                  shorter period, the relevant Advance shall be a Base Rate
                  Advance during such period. The "Applicable LIBO Rate Margin"
                  shall mean the following per annum interest rate from time to
                  time, determined for each fiscal quarter by reference to the
                  Percentage Outstanding for the immediately prior fiscal
                  quarter, in accordance with the following schedule:

                                                              Applicable LIBO

                  each fiscal quarter of the Borrower's fiscal year, determined
                  on the first day of each fiscal quarter depending upon the
                  Percentage Outstanding for the immediately prior quarter.
                  (During the first quarter of this Agreement, commencing July
                  1, 2001, the Applicable LIBO Rate Margin shall be 2.50%.) No
                  more than four (4) LIBO Rate tranches at any one time are
                  permitted for the Note. The Borrower will comply with the
                  provisions of Addendum I hereto, relating to the LIBO Rate,

                  obligation owed to, or a claim by, a Person other than the

                  jurisprudence, statute or contract, and including but not
                  limited to the lien or security interest arising from a
                  mortgage, encumbrance, pledge, security agreement, production
                  payment, conditional sale or trust receipt or a lease,
                  consignment or bailment for security purposes. The term
                  "Lien" shall include reservations, exceptions, encroachments,
                  easements, servitudes, usufructs, rights-of-way, covenants,
                  conditions, restrictions, leases, and other title exceptions
                  and encumbrances affecting property. For the purposes of this
                  Agreement, the Borrower shall be deemed to be the owner of
                  any property which it has accrued or holds subject to a
                  conditional sale agreement, financing lease or other
                  arrangement pursuant to which title to the property has been

                  this Agreement. The Monthly Borrowing Base Reduction may be
                  revised by Lender at any time, and from time to time. The
                  Lender shall notify the Borrower of each Monthly Borrowing
                  Base Reduction redetermination by the Lender, which
                  redetermination shall become effective upon written

                  in effect until redetermined by the Lender in accordance with
                  this Agreement. Without limiting the foregoing, the Lender
                  shall redetermine the Monthly Borrowing Base Reduction as
                  part of each redetermination of the Borrowing Base under this
                  Agreement. On the Closing Date, the Monthly Borrowing Base
                  Reduction is established at $50,000.00.

                  "Note" shall mean the note described in Section 2.1(a)

                  related to hydrocarbons which the Borrower enters into with

                  "Person" shall mean any individual, corporation, limited
                  liability company, partnership, joint venture, association,

                  government or any agency or political subdivision thereof, or

                  maintained by the Borrower, or any such plan to which the

                  and in the amount by which said index rate shall fluctuate,
                  with each such change in the Prime Rate to be effective as of
                  the date of each change in such index rate. The Wall Street

                  necessarily represent the lowest or best rate actually
                  charged to any customer by Lender (or by such institutions
                  comprising said index).

                  "Subsidiary" shall mean each corporation of which the

                  Borrower owns, direct or indirect, fifty percent (50%) or
                  more of the outstanding partnership, membership or other
                  ownership or voting interest.

                  Section 1.3 Accounting Terms. Unless otherwise specified
herein, all accounting terms used herein shall be interpreted, all accounting
determinations hereunder shall be made, and all financial statements required
to be delivered hereunder shall be prepared in accordance with generally
accepted accounting principles as in effect from time to time on a basis
consistent (except for changes in accounting principles or practice approved by
independent public accountants for the Borrower) with the most recent financial
statements of the Borrower.

                                                     ARTICLE 2

                                                    THE CREDIT

                  Section 2.1 Line of Credit and Letters of Credit. (a) Line of
Credit. Subject to and upon the terms and conditions contained in this
Agreement, and relying on the representations and warranties contained in this
Agreement, on the Closing Date the Lender agrees to make a revolving line of
credit available to the Borrower, including the face amount of all standby
letters of credit permitted to be issued under this Agreement, in the maximum
aggregate principal amount equal to the Commitment Limit. The line of credit is
represented by a promissory note in the principal amount of the Amount, payable
to the order of the Lender. Principal and all accrued and unpaid interest on
the line of credit shall be payable in full on the Maturity Date, after which
no further Advances will be made. Payments may be debited from the Borrower's
accounts at the Lender as provided in this Agreement.

                  (b) Interest. The interest rate applicable to each Loan
Advance beginning on the date such Advance is made shall be either (i) the Base
Rate, adjusted daily, or (ii) the LIBO Rate, adjusted on the first day of each
LIBO Rate Interest Period and remaining fixed for the

                                      -9-

<PAGE>

duration of the LIBO Rate Interest Period, selected at the Borrower's option by
written notice to Lender in accordance with the terms hereof. Effective on the
first day following the end of any LIBO Rate Interest Period, the Borrower may
from time to time change the interest rate which is to apply to the Advances or
a portion thereof (including any yet to be made Advance which is made on the
effective date of the interest rate change) by notifying the Lender of the
Borrower's desire to change the interest rate not less than three (3) Business
Days prior to the date on which such change shall be effective. No more than
four (4) LIBO Rate tranches and one Base Rate tranche (all Base Rate Advances
constituting one tranche) shall be permitted for the Note at any one time. In
the absence of any timely specific interest rate election by the Borrower (as
provided above in this Subsection 2.1(b) and in the definition of LIBO Rate),
unless otherwise agreed by the Lender, an Advance (if outstanding as a LIBO
Rate Advance) will be automatically converted into a Base Rate Advance on the
last day of the then current LIBO Rate Interest Period for such Advance or (if
not then outstanding) an Advance shall bear interest at the Base Rate. The
Borrower further will comply with the provisions of Addendum I hereto, relating
to the LIBO Rate, which is an integral part of this Agreement. Interest on the
Note shall be payable (x) on Advances bearing interest at the Base Rate monthly
in arrears on the last day of each month, beginning July 31, 2001, and (y) on
LIBO Rate Advances on the last day of each applicable LIBO Rate Interest Period
for each LIBO Rate Advance. Interest on (i) Base Rate Advances and all other
Indebtedness except for LIBO Rate Advances shall be calculated on the basis of
a 365 (or in a leap year 366) day year and the actual number of days elapsed,
and (ii) on LIBO Rate Advances shall be calculated on the basis of a 360-day
year by applying the ratio of the annual interest rate over a year of 360 days,
times the applicable principal balance, times the actual number of days such
applicable principal balance is outstanding. Payments may be debited from the
Borrower's accounts at the Lender as provided in this Agreement.

                  (c) Draw Requests. In accordance with the provisions in this
Section, the Lender will make Advances to the Borrower from time to time on any
Business Day on and after the Closing Date until and including the last
Business Day before the Maturity Date in such amounts as the Borrower may
request, up to the Commitment Limit, and the Borrower may make borrowings,
repayments and reborrowings in respect thereof. Requests for Advances must be
made by written notice from the Borrower sent to the Lender by mail, courier or
facsimile in accordance with Section 9.1, specifying the amount of the Advance.
A request shall be fully authorized by the Borrower if made by any one of the
Persons hereby designated by the Borrower as an authorized person in accordance
with resolutions of the Board of Directors (or its Executive Committee) of the
Borrower certified to the Lender. The Lender may rely fully and completely upon
the authority of the signatory of such request or confirmation unless such
authority is terminated by written notice to the Lender, and any such
termination shall be effective only prospectively. The request for any Advance
by the Borrower shall constitute a certification by the Borrower that all of
the representations and warranties contained in Article 4 (other than those
representations and warranties, if any, that are by their specific terms
limited in application to a specific date) are true and correct as of the date
of such request and also as of the date of the Advance.

                  (d) Timing After the Lender's receipt of an authorized
request for Advance, the Lender will make such Advance for the benefit of the
Borrower in same day funds as provided below upon fulfillment of the applicable
conditions set forth in this Agreement. Requests for Advances at the Base Rate
shall be made on written notice from the Borrower to the Lender, received by
the Lender no later than 11:00 a.m. (Central Time) on the first Business Day
before such Base Rate Advance specifying the amount thereof. Request for
Advances at the LIBO Rate shall be made on written notice from the Borrower to
the Lender received by the Lender no later than 11:00 a.m. (Central Time) on
the third (3rd) Business Day before such LIBO Rate Advance, specifying the
amount thereof (including the amount of each tranche, if more than one) and the
LIBO Rate Interest Period (or Interest Periods, if more than one tranche). Each
such written notice by the Borrower shall be irrevocable by the Borrower. Not
later than 3:00 p.m. (Central Time) on the date properly and timely requested
for the Advance and upon fulfillment of the applicable conditions set forth in
Article 7 of this Agreement, the Lender will make such Advance available to the
Borrower in same day funds in the deposit account maintained by the Borrower
with the Lender. The Borrower irrevocably agrees in favor of the Lender that
the deposit of the proceeds of any Advance in the Borrower's account with the
Lender shall be deemed prima facie evidence of the Borrower's Indebtedness to
the Lender under the Loan.

                  (e) Minimum. Notwithstanding anything in this Agreement to
the contrary, the aggregate principal amount of all LIBO Rate Advances having
the same LIBO Rate Interest Period shall be at least equal to $100,000.00; and
if any LIBO Rate tranche would otherwise be in a lesser principal amount for
any period, such tranche shall bear interest at the Base Rate during such
period.

                  (f) Letters of Credit. As a portion of the line of credit
availability (and subject to the Commitment Limit and the other terms and
conditions of this Agreement), the Lender will issue standby letters of credit
for the account of the Borrower. The expiration of such letters of credit shall
not extend beyond the Maturity Date of the line of credit. The fee for a
standby letter of credit shall be at the per annum rate equal to the Applicable
LIBO Rate Margin then in effect on the face amount of the letter of credit for
the period from the letter of credit's issuance to the expiration date, paid
quarterly in arrears on each September 30, December 31, March 31 and June 30,
plus additional amounts customarily charged by the Lender for the issuance and
processing of letters of credit. The Borrower shall submit an application for
each letter of credit on the Lender's standard form. Such letters of credit
will be documented on the Lender's standard form. No letter of credit will be
issued if the face amount thereof plus the aggregate of all Advances then
outstanding plus the face amount of all standby letters of credit then
outstanding would exceed the Commitment Amount. Payment by the Lender of a draw
on a standby letter of credit shall be an Advance as part of the Loan bearing
interest from the date of such draw, notwithstanding the Commitment Limit.

                  Section 2.2 Business Days. If the date for any payment,
prepayment or fee payment hereunder falls on a day which is not a Business Day,
then for all purposes of this Agreement (unless otherwise provided herein) the
same shall be deemed to have fallen on the

                                      -11-

<PAGE>

next following Business Day, and such extension of time shall in such case be
included in the computation of payments of interest.

                  Section 2.3 Payments. The Borrower shall make each payment
hereunder and under the Note and any Collateral Documents in lawful money of
the United States of America in same day funds to the Lender at its main office
in New Orleans, Louisiana, not later than 11:00 a.m. (Central Time) on the day
when due, or such other place in the United States as designated in writing by
the Lender. The Borrower hereby authorizes the Lender to charge from time to
time against the Borrower's accounts with the Lender any amount so due, and
acknowledges that the revenue distribution account (Section 5.17) is
established for that purpose and may be so used even in the absence of an Event
of Default.

                  Section 2.4 Prepayment. (a) Voluntary. The Borrower may
prepay the Loan in full or in part at any time without payment of premium or
penalty; provided, however, that (i) the Borrower shall give the Lender notice
of each such prepayment of all or any portion of a LIBO Rate Advance no less
than three (3) Business Days prior to prepayment, (ii) any LIBO Rate Advance
may be prepaid only on the last day of the Interest Period for such LIBO Rate
Advance, (iii) the Borrower shall give the Lender notice of each such
prepayment of all or any portion of a Base Rate Advance no less than one (1)
Business Day prior to prepayment, (iv) the Borrower shall pay all accrued and
unpaid interest on the amounts prepaid, and (v) no such prepayment shall serve
to postpone the repayment when due of any other Indebtedness.

                  (b) Mandatory. The Lender shall notify the Borrower of the
result of each Borrowing Base redetermination by the Lender. If at any time the
Lender determines that a Loan Excess exists, then within thirty (30) days of
receipt by the Borrower of notice of such Loan Excess the Borrower shall (x)
prepay the Advances (together with accrued interest on the amount to be prepaid
to the date of payment) in an amount sufficient to reduce the Advances plus the
face amount of all standby letters of credit then outstanding to the then
Commitment Limit, and/or (y) execute, deliver and record or cause to be
executed and delivered such additional Collateral Documents pursuant to Section
2.1, sufficient to induce the Lender to make an increased redetermination of
the Borrowing Base to an amount not less than the outstanding principal balance
of the Advances plus the face amount of all standby letters of credit then
outstanding. The Borrower specifically acknowledges that no additional grace
period (beyond the period stated in the preceding sentence) is applicable under
this Agreement to any failure to make such mandatory prepayment before such
failure is an Event of Default hereunder.

         (c) Monthly Borrowing Base Reductions. Subject to the other provisions
of this Agreement, the Borrowing Base shall be automatically reduced by the
Monthly Borrowing Base Reduction commencing on July 31, 2001, and continuing on
the last day of each successive month. Notwithstanding the foregoing provisions
in Subsection 2.4(b), the Borrower shall pay the amount of any Loan Excess that
would result from the application of each Monthly Borrowing Base Reduction on
or before the day that such Monthly Borrowing Base Reduction becomes
applicable.

                                      -12-

<PAGE>

                  Section 2.5 Fees. (a) The Borrower shall pay the Lender a
commitment fee in the amount equal to $25,000.00 (0.50% of the Amount of
$5,000,000.00) in two equal installments. The first payment of $12,500.00 shall
be paid on or before the Closing Date, and the second payment of $12,500.00
shall be paid by the Borrower to the Lender on the Closing Date.

                  (b) The Borrower shall pay the Lender an unused facility fee
quarterly in arrears beginning September 30, 2001 (for the period from the
Closing Date through such date) and on the last day of each succeeding
December, March, June and September and on the Maturity Date of the Loan, in an
amount equal to one-half of one percent (0.50%) per annum on (x) the Amount
less (y) the average outstanding principal balance of the Note plus the face
amount of all standby letters of credit then outstanding during such quarter
(or lesser time period, as applicable.)

                  (c) The Borrower agrees to reimburse Lender quarterly in
arrears on the last day of each fiscal quarter for Lender's actual costs, if
any, incurred during that quarter for Lender's compliance with its
environmental verification process in obtaining environmental status reports or
similar information from governmental agencies such as the Utah Department of
Natural Resources.

                  (d)  Letter of Credit fees are paid as provided in
Subsection 2.1(f).

                  Section 2.6 Use of Proceeds. The Borrower shall use the
proceeds of the Loan in connection with the acquisition of oil and gas
properties as well as general working capital purposes (including letters of
credit hereunder) and development and drilling activities and the refinancing
of the Debt existing on the Closing Date.

                  Section 2.7 Default Rate. Anything in the Note or in any
other agreement, document or instrument to the contrary notwithstanding,
effective upon an Event of Default or upon the Maturity Date, the Lender shall
have the right to prospectively increase the interest rate under the Note to
the Default Rate until the Note is paid in full. Upon the acceleration of the
principal amount of the Indebtedness represented by the Note, the accelerated
principal balance of the Loan shall bear interest from the date of acceleration
up to the actual payment (as well after as before judgment) at the Default
Rate. All such interest at the Default Rate shall be payable upon demand.

                  Section 2.8 Additional Regulatory Costs. If any governmental
authority, central bank, or other comparable authority shall at any time
impose, modify or deem applicable any reserve (including without limitation any
imposed by the Board of Governors of the Federal Reserve System), special
deposit or similar requirement against assets of, deposits with or for the
account of, or credit extended by, the Lender, or shall impose on the Lender
any other condition affecting an Advance or the obligation of the Lender to
make an Advance; and the result of any of the foregoing is to increase the cost
to the Lender of making or maintaining the Advances to the Borrower, or to
reduce the amount of any sum received or receivable by the Lender under this

                                      -13-

<PAGE>

Agreement or under the Note by an amount deemed by the Lender to be material,
then, within sixty (60) days after demand by the Lender, the Borrower shall pay
to the Lender such additional amount or amounts as will compensate the Lender
for such increased cost or reduction. The Lender will promptly notify the
Borrower of any event of which it has knowledge, occurring after the date
hereof, which will entitle the Lender to compensation pursuant to this Section.
A certificate of the Lender claiming compensation under this Section and
setting forth the additional amount or amounts to be paid to it hereunder shall
be conclusive in the absence of manifest error.

                                   ARTICLE 3

                          SECURITY FOR THE OBLIGATIONS

                  Section 3.1  Security.  The Loan shall be primarily secured
by the following:

                  (i) Mortgage, Deed of Trust, Assignment, Security Agreement
and Financing Statement executed by the Borrower, granting a first priority
mortgage, security interest and assignment of production in the Borrower's
interests in various oil and gas properties in the States of Texas, Utah and
Oklahoma (and after the Closing Date in future locations as Borrower and Lender
may agree from time to time).

                  (ii) Revenue AccountAgreement executed by the Borrower and
the Lender, establishing a revenue distribution account at the Lender for the
direct deposit of payments on all production proceeds from the Collateral, from
which interest and other payments on the Loan may be debited.

                                                     ARTICLE 4

                                          REPRESENTATIONS AND WARRANTIES

                  In order to induce the Lender to enter into this Agreement,
the Borrower represents and warrants to the Lender (which representations and
warranties will survive the extensions of credit under this Agreement) that:

organized, legally existing and in good standing under the laws of its state of
incorporation (Delaware) and is duly qualified as foreign corporation in Texas,

the Note and the Collateral Documents do not and will not violate any
provisions of the Borrower's articles of incorporation or bylaws, will not
violate any contract, agreement, law, regulation, order, injunction, judgment,
decree or writ to which the Borrower is subject, and will not result in the
creation or imposition of any Lien upon any property of the Borrower other than

                  Section 4.6 No Consent. The Borrower's execution, delivery
and performance of this Agreement, the Note and the Collateral Documents do not
require the consent or approval of any other Person, including without
limitation any regulatory authority or governmental body of the United States
or any state thereof or any political subdivision of the United States or any
state thereof (including without limitation the federal Bureau of Land
Management, the Utah School and Institutional Trust Lands Administration and

                  Section 4.7 Financial Condition. All financial statements of
the Borrower and any affiliates delivered to Lender fairly present the
financial condition of the parties for whom such statements are submitted and
the financial statements of the Borrower and any affiliates have been prepared
in accordance with generally accepted accounting principles consistently

liabilities, or financial condition of Borrower or any affiliates. No event has
occurred (including, without

limitation, any litigation or administrative proceedings) and no condition
exists or, to the knowledge of Borrower, is threatened, which (i) might render
Borrower unable to perform its obligations under this Agreement, the Note or

affiliates or the validity or priority of the Lien of the Collateral Documents.
The Borrower is solvent and with this Agreement has the ability to pay its
Debts when and as due.

to the Lender, there is no litigation, legal or administrative proceeding,
investigation or other action of any nature pending or, to the knowledge of
Borrower, threatened against or affecting the Borrower which involves the
possibility of any judgment or liability not fully covered by insurance which
may materially and adversely affect the business or the property of the
Borrower or its ability to carry on business as now conducted.

                  Section 4.11 Margin Stock. None of the Loan proceeds will be

indebtedness which was originally incurred to purchase or carry a margin stock

credit" within the meaning of said Regulation U. The Borrower is not engaged
principally, or as one of the Borrower's important activities, in the business
of extending credit for the purpose of purchasing or carrying margin stocks.

U or any other regulation of the Board of Governors of the Federal Reserve
System or to violate the Securities Exchange Act of 1934 or any rule or
regulation thereunder, in each case as now in effect or as the same may
hereinafter be in effect.

regulations on the date of this Agreement, has been installed in any Collateral
constituting real property. Such real property and the Borrower are not in

correct following disclosure to the applicable governmental authorities of all
relevant facts, conditions and circumstances, if any, pertaining to such
property and known to the Borrower. No hazardous substances or solid wastes
have been disposed of or otherwise released on or to such property. The terms
"hazardous substance" and "release" as used in this Agreement shall have the
meanings specified in CERCLA, and the terms "solid waste" and "disposal" (or
"disposed") shall have the meanings specified in RCRA; provided, in the event

                  Section 4.19 Contracts. The Contracts when considered as a
whole do not materially affect the rights, benefits or security of the Lender
under the Collateral Documents and the Contracts do not contain any provision
which would prevent the Lender's practical realization of the benefits of the
Collateral Documents as to the Collateral. After giving effect to the
Contracts, the net revenue interests of the Borrower in the Collateral are not
less than those set forth in the Collateral Documents.

                  Section 4.20 Affiliates. The Borrower has no Subsidiaries,
other than Texplor T&T Corporation. None of the Collateral is owned by, or has

interest, membership interest or otherwise).

Borrower has no subordinated Debt of the type permitted by Section 6.1(f). On

and warranties contained in this Article or elsewhere in this Agreement shall
be true in all material respects through and until the date on which all
obligations of Borrower under this Agreement, the Note and the Collateral
Documents and any other documents executed in connection therewith are fully
satisfied, and Borrower shall promptly notify Lender of any event which would
render any of said representations and warranties materially untrue or
misleading.

                             AFFIRMATIVE COVENANTS

                  Unless the Lender's prior written consent to the contrary is

Indebtedness is outstanding.

of engineers, auditors and accountants, travel expenses and investigation
expenses reasonably incurred by the Lender in connection with any such matters,
together with interest at the Default Rate on each such amount from the date

documentary stamp taxes or other similar taxes, if any, which may be payable or

                        first (91st) day after the Closing Date, the Borrower
                        shall maintain, on a quarterly basis as of the last

                        (x) current assets plus the unused and available
                        portion of the Commitment Limit (being the amount, if
                        any, by which the Commitment Limit then in effect
                        exceeds the outstanding principal balance of the
                        Advances plus the face amount of all outstanding
                        standby letters of credit issued hereunder), to (y)
                        current liabilities. Unpaid royalties are to be
                        classified as current liabilities and included in this

                        worth of not less than $1,866,600.00 on the Closing
                        Date, and thereafter shall maintain, on

                                      -26-

<PAGE>

                        a quarterly basis as of the last day of each fiscal
                        quarter, the minimum net worth requirement as re-set
                        annually on the following basis: This minimum net
                        worth requirement shall be re-set annually after the
                        end of each fiscal year as to the amount to be met
                        as of the end of each quarter during the new fiscal
                        year, with the amount for the new fiscal year being
                        increased (but not reduced) by (x) fifty (50%)
                        percent of the Borrower's and all Subsidiaries'
                        prior fiscal year's positive net income on a
                        consolidated basis plus (y) one hundred (100%)
                        percent of the net proceeds from stock or other
                        equity offerings of any nature by the Borrower or
                        any Subsidiary. For purposes of this covenant, such
                        number shall be adjusted to exclude non-cash items,
                        including unrealized gains and losses, arising from
                        the effects, if any, of the mark to market of those
                        Hedging Obligations which are classified as cash
                        flow hedges and determined "effective" pursuant to
                        Financial Accounting Standards Board Rule No. 133
                        (Accounting for Derivative Instruments and Hedging
                        Activities), or of other rules pertaining to other
                        comprehensive income.

                  (c)   Minimum EBITDAX to Interest.  The Borrower shall
                        maintain, on a quarterly basis as of the last day of
                        each fiscal quarter, a ratio (on a rolling four fiscal
                        quarter basis) of EBITDAX to interest expense of not
                        less than 2.00 to 1.00 through December 31, 2001, and
                        of not less than 2.50 to 1.00 thereafter. For purposes
                        of this Subsection, interest expense shall mean, for
                        each period, the sum of all interest, fees, charges
                        and related expenses payable (without duplication) for
                        that period to a lender in connection with borrowed
                        money or the deferred purchase price of assets that
                        are considered "interest expense" under generally
                        accepted accounting principles, plus the portion of
                        rent paid or payable (without duplication) for that
                        period under capital lease obligations that should be
                        treated as interest in accordance with Financial
                        Accounting Standards Board Statement No. 13. "EBITDAX"
                        shall be calculated for purposes of this Subsection as
                        EBITDA, but adjusted as if the Borrower were to use
                        the full cost method of accounting (under which all
                        exploration expenses are capitalized) to capitalize
                        exploration and dry hole costs rather than the
                        Borrower's successful efforts accounting method of
                        expensing intangible drilling costs (such as seismic
                        and geological expenses), dry hole costs and other
                        costs. For purposes of this Subsection, "EBITDA" shall
                        mean, for each period of four preceding fiscal
                        quarters, the sum of the Borrower's (i) net income for
                        that period, plus (i) any extraordinary loss and other
                        expenses not considered to be operating in nature
                        reflected in such net income, minus (iii) any
                        extraordinary gain, interest income and other income
                        not considered operating in nature reflected in such
                        net income, plus (iv) depreciation, depletion,
                        amortization and all other non-cash expenses for that
                        period, plus (v) all interest, fees, charges and
                        related

                        expenses paid or payable (without duplication) for
                        that period to a lender in connection with borrowed
                        money or the deferred purchase price of assets that
                        are considered "interest expense" under generally
                        accepted accounting principles, together with the
                        portion of rent paid or payable (without
                        duplication) for that period under capital lease
                        obligations that should be treated as interest in
                        accordance with Financial Accounting Standards Board
                        Statement No. 13, plus (vi) the aggregate amount of
                        federal and state taxes on or measured by income for
                        that period (whether or not payable during that
                        period).

                  Section 5.16 Bank Accounts. (a) The Borrower shall maintain
its primary operating, collection and disbursement accounts pertaining to the
Collateral at the Lender, including without limitation as provided in Section
5.17.

                  (b) The Borrower hereby grants to the Lender a continuing
security interest in all of Borrower's deposit accounts now existing or
hereafter maintained at Lender as security for the Indebtedness, and all funds,
investment property and proceeds pertaining thereto.

                  Section 5.17 Revenue Distribution Account and Transfer
Orders. (a) The Borrower shall execute such division orders, transfer orders or
letters in lieu thereof as are necessary to direct that payments of production
from the Collateral are paid directly to the Lender into the revenue
distribution account (Section 3.1(ii)) at all times. Without limiting the
foregoing, the Borrower shall cause all purchasers from or agents of Borrower
to make all payments for oil or natural gas purchases from the Collateral to be
paid directly to such revenue distribution account at the Lender. The Borrower
shall maintain the revenue distribution account and an lockbox operating
agreement in effect with the Lender at all times. If no Default has occurred
and is continuing, proceeds in the revenue distribution account exceeding the
next monthly payment amount may be transferred or withdrawn by the Borrower.

                  (b) The Borrower and the Lender acknowledge that Collateral
is comprised in part of the Borrower's undivided interests in mineral
properties for which the Borrower is operator, and accordingly a portion of the
payments made to the Borrower from the sale of hydrocarbons from such
properties may be owed by the Borrower to the non-operator working interest
owners. In the event that revenues of another Person attributable to such other
Person's working interest ("Other Revenues") are deposited into the revenue
distribution account, then the Lender agrees that such Other Revenues will be
released by the Lender to such Persons (even if an Event of Default has
occurred and is continuing) upon the receipt by the Lender of appropriate
evidence that such funds are Other Revenues (i.e., are not the Borrower's
funds). The Lender shall not be liable, however, for any actions by Lender
which are taken in compliance with the terms of this Agreement and the
Collateral Documents with respect to funds in the revenue distribution account
that are Other Revenues and which are taken before Lender received such
evidence that such funds are Other Revenues.

                           borrowed money and that are taken into account in

The inclusion of this Section 6.2 shall not constitute in any way an
acknowledgment by the Lender of the validity, legality, enforceability or
binding effect on the Lender of such Liens, the sole purpose of this provision

                           Documents shall for any reason cease to be valid and
                           binding on the Borrower after the Closing Date, or
                           the Borrower shall so assert in writing.

                  Section 8.2 Remedies. (a) Upon the happening of any Event of

written notice to the Borrower declare the entire principal amount of all

hereby expressly waived by the Borrower.

                  (b) Upon the happening of any Event of Default specified in
Subsections (g) or (h) of the preceding Section, (i) all obligations, if any,
of the Lender to make Advances to the Borrower shall immediately cease and
terminate, and (ii) the entire principal amount of all obligations then
outstanding including interest accrued thereon shall, without notice or action

all of which are hereby expressly waived by the Borrower.

                  (c) In addition to the foregoing, the Lender may exercise any
of the rights and remedies established in the Collateral Documents or avail
itself of any other rights and remedies provided by applicable law.

standby letters of credit are outstanding upon the occurrence of any Event of
Default, the Lender may be written notice to the Borrower require the Borrower
to pay to the Lender immediately on such demand the full face amount of such
letters of credit to be held by the Lender as collateral for the payment of
such letters of credit.

Borrower to the Lender pursuant to the Agreement (but the Borrower acknowledges
that the Lender may apply funds in the revenue distribution account (Section
5.17) against any amounts due and payable by the Borrower even without the
occurrence of an Event of Default). The Borrower agrees that any holder of a
participation in the Note may exercise any and all rights of counter-claim,
set-off, banker's lien and other liens with respect to any and all monies owing
by Borrower to such holder as fully as if such holder of a participation were a
holder of a note in the amount of such participation.

hereafter assert any right under any law pertaining to marshaling (whether of

the Collateral Documents set forth the entire agreement of the Lender and the
Borrower with respect to the Indebtedness, and supersede all prior written or
oral understandings with respect thereto; provided, however, that all written
representations, warranties and certifications made by the Borrower to the
Lender with respect to the Indebtedness and the security therefor shall survive
the execution of this Agreement. The Borrower is not relying on any
representation by the Lender, and no representation has been made, that the
Lender will, at the time of a Default or at any other time, waive, negotiate,
discuss, or take or refrain from taking any action with respect to such
Default.

                  Section 9.3 Renewal, Extension or Rearrangement. All
provisions of this Agreement relating to the Note shall apply with equal force
and effect to each and all promissory notes or security instruments hereinafter

period, increase or rearrangement of any part of the Note.

                  Section 9.4 Amendment. Neither this Agreement nor any
provisions hereof may be changed, waived, discharged or terminated orally or in
any manner other than by an instrument in writing signed by the party against

the provisions contained in this Agreement, the Note, or the Collateral
Documents shall, for any reason, be held invalid, illegal or unenforceable in
any respect, such invalidity, illegality or unenforceability shall not affect
any other provision of this Agreement, the Note or the Collateral Documents.

                  Section 9.6 Survival of Agreements. All representations and
warranties of the Borrower herein, and all covenants and agreements herein not
fully performed before the effective date of this Agreement, shall survive such
date.

                  Section 9.7 Waivers. No course of dealing on the part of the
Lender, its officers, employees, consultants or agents, nor any failure or
delay by the Lender with respect to exercising any of its rights, powers or
privileges under this Agreement, the Note or the Collateral Documents, shall
operate as a waiver thereof.

                  Section 9.8 Cumulative Rights. The rights and remedies of the
Lender under this Agreement, the Note and the Collateral Documents shall be
cumulative, and the exercise or partial exercise of any such right or remedy

assigns and shall inure to the benefit of the Lender and its successors and
assigns. The Borrower may not assign its rights or obligations under this
Agreement.

                  (b) This Agreement is for the benefit of the Lender and for
such other Person or Persons as may from time to time become or be the holders
of any of the Indebtedness, and this Agreement shall be transferrable and
negotiable, with the same force and effect and to the same extent as the
Indebtedness may be transferrable, it being understood that, upon the transfer
or assignment by the Lender of any of the Indebtedness, the legal holder of
such Indebtedness shall have all of the rights granted to the Lender under this
Agreement.

                  (c) The Borrower hereby recognizes and agrees that the Lender
may, from time to time, one or more times, transfer all or any portion of the
Indebtedness to one or more third parties. Such transfers may include, but are
not limited to, sales of participation interests in such Indebtedness in favor
of one or more third party lenders. Borrower specifically (i) consents to all
such transfers and assignments, waives any subsequent notice of and right to
consent to any such transfers and assignments as may be provided under
applicable Louisiana law; (ii) agrees that the purchaser of a participation
interest in the Indebtedness will be considered as the absolute owner of a
percentage interest of such Indebtedness and that such a purchaser will have
all of the rights granted to the purchaser under any participation agreement
governing the sale of such a participation interest; (iii) waives any right of
offset that Borrower may have against the Lender, and/or any purchaser of such
a participation interest in the Indebtedness, and unconditionally agrees that
either the Lender or such a purchaser may enforce Borrower's Indebtedness under
this Agreement, irrespective of the failure or insolvency of the Lender or any
such purchaser; (iv) agrees that any purchaser of a participation interest in
the Indebtedness may exercise any and all rights of counter-claim, set-off,
banker's lien and other liens with respect to any and all monies owing to the
Borrower; and (v) agrees that, upon any transfer of all or any portion of the
Indebtedness, the Lender may transfer and deliver any and all collateral
securing repayment of such Indebtedness to the transferee of such Indebtedness
and such collateral shall secure any and all of the Indebtedness in favor of
such a transferee, and after any such transfer has taken place, the Lender
shall be fully discharged from any and all future liability and responsibility
to Borrower with respect to such collateral, and the transferee thereafter
shall be vested with all the powers, rights and duties with respect to such
collateral.

                  Section 9.11 Relationship Between the Parties. The
relationship between the Lender and the Borrower shall be solely that of lender
and borrower, and such relationship shall not, under any circumstances
whatsoever, be construed to be a joint venture, joint adventure, or
partnership. The Lender has no fiduciary obligation to the Borrower with
respect to this Agreement or the transactions contemplated hereby.

                                                                       Page -1-

                                   ADDENDUM I

                              LIBO RATE PROVISIONS

         1. The Lender shall determine the interest rate applicable to LIBO
Rate Advances, and its determination shall be conclusive in the absence of
manifest error. The Lender shall endeavor to notify the Borrower prior to the
date on which an interest payment is due, provided that the failure of the
Lender to provide such notice shall not affect the Borrower's obligation to pay
interest on such date.

         2. If any applicable law or regulation, or the action of any
applicable regulatory requirement increases the reserves or capital required to
be maintained by the Lender with respect to the Loan (including unfunded
commitments and obligations on letter of credit), the Lender shall promptly
deliver a certificate to the Borrower specifying the additional amount as will
compensate the Lender for the additional costs, which certificate shall be
conclusive in the absence of manifest error. The Borrower shall pay the amount
specified in such certificate promptly upon receipt.

         3. If the Lender gives notice to the Borrower that no LIBO bid rate is
quoted to the Lender (or otherwise that adequate and reasonable methods do not
exist for ascertaining the LIBO Rate) for the applicable Interest Period or in
the applicable amounts (which notice shall be conclusive and binding on the
Borrower absent manifest error), then (A) the obligation of the Lender to make
a LIBO Rate Advance and the ability of the Borrower to select the LIBO Rate for
an Advance shall be suspended, and (B) the Borrower shall either prepay all
LIBO Rate Advances for which an interest rate is to be determined on such date
or the Loan shall thereafter bear interest at the Base Rate.

         4. If any applicable domestic or foreign law, treaty, rule or
regulation (whether now in effect or hereinafter enacted or promulgated,
including Regulation D of the Board of Governors of the Federal Reserve System)
or any interpretation or administration thereof by any governmental authority
charged with the interpretation or administration thereof (whether or not
having the force of law):

                  (i) changes the basis of taxation of payments to the Lender
         or any principal, interest, or other amounts attributable to any LIBO
         Rate Advance (other than taxes imposed on the overall net income of
         the Lender);

                  (ii) changes, imposes, modifies, applies or deems applicable
         any reserve, special deposit or similar requirements in respect of any
         such LIBO Rate Advance (excluding those for which the Lender is fully
         compensated pursuant to adjustments made in the definition of LIBO
         Rate) or against assets of, deposits with or for the account of, or
         credit extended by, the Lender; or

                                                                     ADDENDUM I
                                                                       Page -2-

                  (iii) imposes on the Lender or the interbank eurocurrency
         deposit and transfer market any other condition or requirement
         affecting any such LIBO Rate Advance,

and the result of any of the foregoing is to increase the cost to the Lender of
funding or maintaining any such LIBO Rate Advance (other than costs for which
the Lender is fully compensated pursuant to adjustments made in the definition
of LIBO Rate) or to reduce the amount of any sum receivable by the Lender in
respect of any such LIBO Rate advance by an amount deemed by the Lender to be
material, then or the Lender shall promptly notify the Borrower in writing of
the happening of such event and (1) Borrower shall upon demand pay to the
Lender such additional amount or amounts as will compensate the Lender for such
additional cost or reduction and (2) Borrower may elect, by giving to the
Lender not less than three Business Days' notice, to change the interest rate
applicable to such Advance, and any other portion of the Loan bearing interest
at the LIBO Rate, to the Base Rate.

         5. Notwithstanding any other provision hereof, if any change in
applicable laws, treaties, rules or regulations or in the interpretation or
administration thereof of or in any jurisdiction whatsoever, domestic or
foreign, shall make it unlawful or impracticable for the Lender to maintain
Advances bearing interest at the LIBO Rate, or shall materially restrict the
authority of the Lender to purchase, sell or take certificates of deposit or
offshore deposits of dollars, then, upon notice by the Lender to Borrower, the
Lender's portion of all LIBO Rate Advances which are then outstanding and which
cannot lawfully or practicably be maintained shall immediately cease to bear
interest at the LIBO Rate and shall commence to bear interest at the Base Rate.
The Borrower agrees to indemnify the Lender and hold it harmless against all
costs, expenses, claims, penalties, liabilities and damages which may result
from any such change in law, treaty, rule, regulation, interpretation or
administration. The Borrower hereby agrees promptly to pay the Lender, upon
demand by the Lender, any additional amounts necessary to compensate the Lender
for any costs incurred by the Lender in making any conversation in accordance
with this Paragraph, including any interest or fees payable by the Lender to
lenders of funds obtained by it in order to make or maintain hereunder its
portion of the Loan accruing interest based on the LIBO Rate.

         6. The Borrower will indemnify the Lender against, and reimburse the
Lender on demand for, any loss or expense incurred or sustained by the Lender
(including without limitation, any loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by the Lender
to fund or maintain LIBO Rate Advances) as a result of (i) any payment or
prepayment (whether authorized or required hereunder or otherwise, including
without limitation a mandatory prepayment when required under Section 2.4(b) of
the Agreement) of all or a portion of any LIBO Rate Advance on a day other than
the day on which the applicable Interest Period ends, (ii) any payment or
prepayment, whether required hereunder

<PAGE>
                                                                     ADDENDUM I
                                                                       Page -3-

or otherwise, of the LIBO Rate Advances made after the delivery, but before the
effective date, of an election to have the LIBO Rate apply to LIBO Rate
Advance, if such payment or prepayment prevents such election from becoming
fully effective, or (iii) the failure of any LIBO Rate Advance to be made by
the Lender or of any such election to become effective due to any condition
precedent to a LIBO Rate Advance not being satisfied or due to any other action
or inaction of Borrower. For purposes of this section, funding losses arising
by reason of liquidation or reemployment of deposits or other funds acquired by
the Lender to fund or maintain LIBO Rate Advances shall be calculated as the
remainder obtained by subtracting: (1) the yield (reflecting both stated
interest rate and discount, if any) to maturity of obligations of the United
States Treasury as determined by the Lender in an amount equal or comparable to
such advance for the period of time commencing on the date of the payment,
prepayment or change of rate as provided above and ending on the last day of
the subject Interest Period, from (2) the LIBO Rate of the subject Interest
Period, times the number of days from the date of payment, prepayment or change
of rate to the last day of the subject Interest Period, divided by 360. Any
payment due under this paragraph will be paid to the Lender within five days
after demand therefor by the Lender.

         7.       The Borrower covenants and agrees that:

                  (i) The Borrower will pay, within five days after notice
         thereof from Lender and on an after-tax basis, all present and future
         income, stamp and other taxes, levies, costs and charges whatsoever
         imposed, assessed, levied or collected on or in respect of any LIBO
         Rate Advance whether or not legally or correctly imposed, assessed,
         levied or collected (excluding taxes, levies, costs or charges imposed
         on or measured by the overall net income of the Lender) (all such
         non-excluded taxes, levies, costs and charges being collectively
         called "Reimbursable Taxes"). Promptly after the date on which payment
         of any Reimbursable Taxes is due pursuant to applicable law, the
         Borrower will, at the request of the Lender, furnish to the Lender
         evidence in form and substance satisfactory to the Lender that
         Borrower has met its obligation under this paragraph.

                  (ii) The Borrower will indemnify the Lender against, and
         reimburse the Lender on demand for, any Reimbursable Taxes paid by the
         Lender and any loss, liability, claim or expense, including interest,
         penalties and legal fees, that the Lender may incur at any time
         arising out of or in connection with the failure of Borrower to make
         any payment of Reimbursable Taxes when due, unless such failure is due
         to the Lender's failure to give notice to Borrower of Borrower's
         obligation to pay such Reimbursable Taxes at least five days prior to
         the date when they are due. Any payment due under this subsection will
         be paid to the Lender within five days after demand therefor by the
         Lender.

                                                                       Page -4-

                  (iii) All payments on account of the principal of, and
         interest on, LIBO Rate Advances and all other amounts payable by
         Borrower to the Lender hereunder shall be made free and clear of and
         without reduction by reason of any Reimbursable Taxes.

                  (iv) If Borrower is ever required to pay any Reimbursable
         Taxes with respect to any LIBO Rate Advance, Borrower may elect, by
         giving to the Lender not less than three (3) Business Days' notice, to
         change the interest rate applicable to any such advance from the LIBO
         Rate to the Base Rate, but such election shall not diminish Borrower's
         obligation to pay all Reimbursable Taxes therefore imposed, assessed,
         levied or collected.
