                                  RISK FACTORS



OUR LIMITED OPERATING HISTORY, HISTORY OF FINANCIAL LOSSES, AND SIGNIFICANT DEBT
  MAY IMPAIR OUR ABILITY TO OBTAIN THE FUNDS NECESSARY TO FUND OUR CAPITAL
  EXPENDITURE NEEDS.



    We commenced operations in 1991 and acquired a substantial portion of our
operating assets through the acquisition of Texstar Petroleum, Inc. in October
1996. Potential purchasers, therefore, have limited historical financial and
operating information upon which to base an evaluation of our performance and
whether to invest in our securities. We have incurred aggregate net operating
losses of $19.9 million as of June 30, 1999. Our working capital deficit was
$41.1 million and our total indebtedness was $63.1 million at June 30, 1999.
This indebtedness places significant restrictions on our ability to access
capital markets. In addition, our indebtedness has several important
consequences, including, but not limited to, the following:



    - our ability to obtain additional financing is limited;



    - our leverage position and the covenants contained in our existing
      contractual arrangements limit our ability to expand our business and take
      advantage of certain business opportunities;



    - our leverage makes us more vulnerable to economic downturns, limits our
      ability to withstand competitive pressures, and reduces our flexibility in
      responding to changing business and economic conditions; and



    - the holders of our convertible preferred stock are subordinate to our debt
      holders in right of payment.



    We have experienced and expect to continue to experience substantial working
capital needs. Our ongoing capital requirements consist primarily of the
following items:



    - funding the remainder of our 1999 capital and exploration budget;



    - payment of preferred dividends not otherwise payable in common stock; and



    - payment of interest on our outstanding 9% convertible debentures and bank
      obligations.



    Our 1999 net capital and exploration budget is $11.3 million (excluding
capitalized interest and overhead). Approximately $2.5 million of the net
capital and exploration budget remains to be used in 1999. No assurance can be
given as to the availability or terms of additional financing that will be
required. If adequate capital resources are not available, we:



    - may be required to curtail our drilling, development and other operations;



    - may not be able to participate in operations proposed by others with an
      interest in our properties and be subjected to applicable non-consent
      penalties; and



    - may not be able to meet certain of our existing contractual obligations.



OUR HISTORICAL INABILITY TO PAY OUR TRADE PAYABLES ON A TIMELY BASIS COULD
  IMPAIR OUR OPERATIONS.



    At June 30, 1999, we had outstanding approximately $14,377,000 of accounts
payable to industry partners and trade creditors. Approximately $12,160,000 of
this amount was past due. On July 12, 1999, we met with our trade creditors to
outline a proposed repayment plan for past-due amounts. This plan included
proposed discounts, payment over an extended period of time and other revised
payment terms. As of September 8, 1999, trade creditors representing over 93% of
our past-due trade payables elected to participate in the repayment plan. Our
trade creditors that have not elected to participate in our repayment plan have
retained their remedies against us and will be able to assert those remedies if
we are unable to pay them. We anticipate funding our payment obligations by
using the proceeds received from a new production payment we recently arranged,
the sale of assets and production revenue. However, there can be no assurance
that these funding sources will be sufficient to repay our past-due trade
payables under the newly negotiated repayment terms.

THE REPORT OF OUR INDEPENDENT ACCOUNTANTS WITH RESPECT TO OUR FINANCIAL
  STATEMENTS DISCUSSES OUR ABILITY TO CONTINUE AS A GOING CONCERN.



    Note 18 to our audited consolidated financial statements states that those
financial statements were prepared assuming that we are able to continue as a
going concern assuming certain events, such as refinancing of our indebtedness
and the anticipated success of certain of our oil and gas wells. There can be no
assurance that all the events described in the going concern note will occur,
and if they do not occur, we may be unable to continue as a going concern.



WE ARE HIGHLY DEPENDENT ON A SMALL NUMBER OF PRODUCING OIL AND GAS WELLS, THE
  LOSS OF PRODUCTION FROM WHICH WOULD HAVE A SERIOUS IMPACT ON OUR ABILITY TO
  CONTINUE OPERATIONS.



    For the first two quarters of 1999, revenue from the K.S. Byrd 31-1#1 well
totaled approximately $1.2 million, or 37% of our total revenue. The K.S. Byrd
31-1#1 well accounted for approximately $2.4 million of our revenues for the
year ended December 31, 1998, or 49% of total revenue. The K.S. Byrd 31-1 #1
will continue to be a major contributor to our net production. After year-end
1998, we put the Howell #1 on production at a high rate of gas flow. For the
first half of 1999, the Howell well contributed revenue of approximately
$602,900. The loss of the production from either of these wells would have a
substantial negative impact on our revenue, and as a result, on our ability to
meet our obligations when due or to participate in other exploration and
development activities.



WE HAVE ENGAGED IN SUBSTANTIAL TRANSACTIONS WITH CERTAIN OF OUR OFFICERS,
  DIRECTORS AND AFFILIATES THAT WERE NOT NEGOTIATED AT ARMS-LENGTH.



    We have engaged in acquisitions, financings and other transactions with
entities that are owned in part by certain of our officers, directors and
affiliates. These transactions did not result from arms length negotiations.
There can be no assurance that better terms would not have been negotiated in
these transactions through arms-length negotiations with unaffiliated third
parties.



A SUBSTANTIAL PORTION OF OUR OUTSTANDING VOTING STOCK IS CONTROLLED BY A FEW
  SHAREHOLDERS THAT HAVE SUBSTANTIAL INFLUENCE OVER OUR BUSINESS DECISIONS.



    At August 31, 1999, our chairman and chief executive officer, Prentis B.
Tomlinson, Jr. and his wife Heather Tomlinson, beneficially owned approximately
37.1% and 7.1%, respectively, of our outstanding common stock. Mr. and Mrs.
Tomlinson are able to exercise significant influence over our affairs, including
election of the board of directors and other matters submitted to a vote of our
stockholders. The interests of the Tomlinsons may differ from our interests in
certain respects and there can be no assurance that the Tomlinsons will not vote
their common stock on matters that come before a vote of our stockholders in
accordance with their own, rather than our, interests.



PURCHASERS OF OUR SECURITIES MUST BEAR THE RISK THAT NO LIQUID TRADING IN THOSE
  SECURITIES WILL EXIST IN ANY UNITED STATES MARKET.



    Our common stock currently is traded on the Vancouver Stock Exchange. There
is no established trading market for any of our securities in the United States,
and we currently do not meet the listing requirements for any national or
regional United States stock exchange. We cannot assure that any of our
securities will be listed on a U.S. exchange, that an active United States
public market will develop for our securities or that holders of our securities
will be able to resell them in the United States.



THE CONVERTIBLE PREFERRED STOCK SUBJECT TO RESALE UNDER THIS PROSPECTUS IS
  SUBORDINATE IN CERTAIN RESPECTS TO OTHER OF OUR ISSUED AND OUTSTANDING
  SECURITIES.



    Our class A, series II convertible preferred stock ranks PARI PASSU with
certain other of our issued and outstanding preferred stock and any new issue of
preferred stock that stipulates a liquidation preference PARI PASSU with the
class A, series II convertible preferred stock. The class A, series II
convertible preferred


                                       6

stock is subordinate to claims of creditors, including holders of our
outstanding debt instruments. We and our subsidiaries may from time to time
incur additional debt. In the event of our liquidation, dissolution or winding
up, our lenders and other creditors and our subsidiaries would be entitled to
payment in full before satisfaction of the liquidation preference on the class
A, series II convertible preferred stock subject to this prospectus.


           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS


    The statements made in this prospectus that are not statements of historical
fact are "forward looking statements." Forward-looking statements generally can
be identified by the use of forward-looking terminology such as "may," "will,"
"expect," "intend," "estimate," "anticipate" or "believe," or similar
terminology.



    The forward-looking statements include discussions about our business
strategy and expectations concerning market position, future operations,
seismic, drilling or exploration operations, profitability, liquidity and
capital resources, and statements concerning the integration into our business
of the operations we have acquired. Although we believe that the expectations in
these statements are reasonable, we cannot give any assurance that those
expectations will be correct or that the risks to investors in this offering
will not occur.


    We caution you not to place undue reliance on these forward-looking
statements, which speak only as of the date of this prospectus.


    Uncertainties are inherent in estimating quantities of proved oil and
natural gas reserves and in projecting future rates of production and timing of
development expenditures, including many factors beyond our control. Reserve
engineering is a subjective process of estimating underground accumulations of
oil and natural gas that cannot be measured in an exact way, and the accuracy of
any reserve estimate is a function of the quality of available data and of
engineering and geological interpretation and judgment. As a result, estimates
made by different engineers often vary from one another. In addition, results of
drilling, testing and production after the date of an estimate may justify
revisions of the estimate, and the revisions, if significant, could change the
schedule of any further production and development drilling. Accordingly,
reserve estimates generally are different from quantities of oil and natural gas
that ultimately are recovered. Drilling and exploration plans are subject to
modification based upon seismic analysis, drilling results, production results,
and capital availability. Capital availability may also be affected by many
factors including market conditions and exploration results.


    Additional important factors that could cause actual results to differ
materially from our expectations are disclosed elsewhere in this prospectus.


    All subsequent written and oral forward-looking statements attributable to
the company or persons acting on its behalf are expressly qualified in their
entirety by such factors.

DIVIDEND POLICY


    To date, we have not paid any cash dividends on our common stock. We intend
to retain our earnings, if any, to provide funds for reinvestment in our
exploration, development and production activities and, therefore, do not
anticipate declaring or paying cash dividends on our common stock in the
foreseeable future. Furthermore, payment of dividends, if any, in the future is
within the discretion of our board of directors and will depend on our earnings,
if any, our capital requirements and financial condition and other relevant
factors. Presently, our payment of cash dividends on our common stock is
restricted under the terms of certain of our financing arrangements. We
currently have the right to pay dividends due on our class A, series I and
series II preferred stock with common stock. To date, we have elected this
option with respect to all dividends due on the class A, series I preferred
stock and anticipate making this option with respect to all dividends on our
class A, series II preferred stock.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS


    The information set forth below should be read in conjunction with our
consolidated financial statements beginning on page F-1 of this prospectus.



RECENT DEVELOPMENTS



    On July 12, 1999, we conducted a meeting with our trade creditors to outline
a proposed repayment plan for past due amounts. The plan included proposed
discounts, payment over an extended time and other revised payment terms. As of
September 8, 1999, creditors representing 93% of past due amounts, for an
aggregate of $11.3 million, elected to participate in the repayment plan.



    In July 1999, we completed an exchange offer and private placement with
European holders of our 9% debentures series I. Approximately $15.1 million of
the debentures' principal amount was exchanged for approximately $15.8 million
principal amount of our class A series II convertible preferred stock. We also
raised approximately $8 million of new equity through a private placement of the
same preferred stock series in Europe. The $8 million of new equity includes
$3.5 million of preferred stock issued to redeem the previously outstanding Old
Ocean prospect bridge loan and to repurchase the net profits interest assigned
to the lenders under that loan. A total of 238,201 shares of preferred stock
were issued in the exchange and private placement. The preferred stock issued
has a dividend rate of 8% payable semi-annually on September 30th and March 31st
in cash or our common stock at our election. The conversion price is Cdn. $0.35
per share. We have the right to redeem the preferred stock in cash at any time
upon thirty days' notice at 105% of the principal amount.



    In August 1999, we sold 37.5% of our interest in the Old Ocean prospect to
Prime Natural Resources. Prime paid us $3.5 million at closing and will pay an
additional $1,978,098 on or before September 16, 1999. The sale proceeds were
used to pay the remaining costs associated with the Old Ocean 3-D seismic survey
and for general corporate purposes.



    Also in August 1999, we completed a new, long-term production financing with
Aquila Energy Capital Corporation in the amount of $26.2 million. This amount
may be increased to $27.7 million based on near term production results in our
Fortenberry well. The new facility also provides for the lender to fund
additional development drilling at our Oakvale Dome field in Mississippi to a
maximum of $3.8 million. The new production financing is secured by our proven
oil and gas properties and is to be repaid through a dedicated portion of the
property income. Terms of the financing include a 12% interest rate and
assignment of 1/16th of our interest in the proven properties following full
repayment of the new production financing. Proceeds from the financing were used
to retire existing senior secured debt.



    August activity also included a private placement of $4 million in new
equity through the issuance of $4.4 million of redeemable class A preferred
stock, series I to investment entities affiliated and managed by EnCap
Investments, L.C. We paid a placement fee of $100,000 to EnCap Investments, L.C.
Proceeds were used to fund arrangements under the trade creditor agreement
described above and for general corporate purposes.

OVERVIEW


    The following matters had a significant impact on our results of operations
and financial position for the six months ended June 30, 1999:



    OUTSTANDING DEBT.  At June 30, 1999, we had outstanding debt of $63.1
million comprised of the following:



    - $36.3 million principal amount of convertible debentures, of which
      approximately $15.1 million was converted into class A, series II
      convertible preferred stock in July 1999;



    - $12.0 million principal amount outstanding under the EnCap credit
      facility;



    - $6.0 million principal amount outstanding under the BOCP credit facility;



    - $2.2 million principal amount outstanding under the Old Ocean loan.
      Repayment of the outstanding balance was made through the issuance of
      class A, series II convertible preferred stock in July 1999;



    - $5.5 million, net of discount, due Shell Capital, Inc.;



    - $1.1 million advanced by certain lenders who invested additional capital
      in us through the exchange offer in July 1999.



    We repaid the EnCap credit facility, the BOCP credit facility and the Shell
financing with funds obtained in connection with the Aquila production payment
financing discussed above and a new note with EnCap in the amount of $2.9
million. The new EnCap note matures December 31, 2000 and accrues interest at a
rate of 10% per annum.



    VOLUME AND PRICE INFORMATION.  Revenue for the first half of 1999 was
significantly impacted by first sales of production from the Howell 32-4 #1 well
(Oakvale Dome development well), the BOE 16-12 #1 well (Wausau exploratory well)
and the BOE 16-14 #1 well (E. Morgantown exploratory well). Production from
these wells averaged 3,698 Mcfe/d, favorably impacting revenue by approximately
$1.3 million for the six months ended June 30, 1999.



    The following table summarizes volume and price information with respect to
our oil and gas production for the six months ended June 30, 1999 and 1998:

    The following had a significant impact on our results of operations and
financial position for the year ended December 31, 1998:



    CAPITALIZATION.  In March and April of 1998, we completed the private
placement of $37.5 million principal amount of 9% convertible debentures. After
expenses and escrow of $1.056 million for the satisfaction of certain put rights
of holders of the 9% convertible debentures (of which approximately $988,000 has
been put), $32.5 million of the proceeds remained available to us. In April
1999, we agreed to lower the conversion price of the debentures from Cdn.$1.70
per common share to Cdn.$1.40 per common share in exchange for certain
amendments to the indentures. Series 3 debentureholders and the Series A


                                       12
<PAGE>

special noteholders have the same amendments. The 9% notes outstanding after the
exchange offer are convertible into 12,859,241 shares of common stock, based on
a conversion price of Cdn.$1.40 and an exchange rate of $0.6696 per Cdn.$1.00
(the exchange rate as of September 7, 1999). The remaining 9% convertible
debentures are convertible into 9,987,859 shares of common stock based on a
current conversion price of Cdn.$1.40, adjusted for a 10% penalty on conversion
due to our failure to meet our contractual obligations to register these
debentures for resale under the Securities Act by a specified deadline.



    DISCOVERY WELL.  The K. S. Byrd Well, which began producing in September of
1997, contributed an average of 2,402 Mcf per day during 1998, before including
747 Mcf per day for acquired interests.



    ACQUISITIONS.  We acquired certain producing properties from Lasco Energy
Partners in January 1998, Calibre Energy, L.L.C. in April 1998 and Southern Gas
Company in May 1998. The assets acquired in these transactions and certain other
acquisitions contributed an average of 2,982 Mcf per day during 1998, of which
747 Mcf per day was additional production to us related to the K. S. Byrd well
not included in the discussion above.



    VOLUME AND PRICE INFORMATION.  Our average realized price for natural gas
decreased $0.56 per Mcf from $2.80 per Mcf for the year ended December 31, 1997
to $2.24 per Mcf for the comparable period in 1998. Income in 1998 from hedging
gains increased gas realizations by $0.18 per Mcf. The average realized oil
price decreased $8.25 per barrel from $19.08 per barrel in 1997 to $10.83 per
barrel in 1998.


    The following table summarizes volume and price information with respect to
our oil and gas production for the years ended December 31, 1998 and 1997, the
four-month period ended December 31, 1997 and the ten-month period ended August

    The amounts for the year ended December 31, 1997 were derived by adding the
audited four month period ended December 31, 1997 and the audited ten month
period ended August 31, 1997 and then subtracting the unaudited two month period
ended December 31, 1996.



    OUTSTANDING DEBT.  At December 31, 1998, we had outstanding debt of $59.5
million, compared to $12.7 million at December 31, 1997. The increase reflects
the issuance of $37.5 million of 9% convertible debentures, proceeds from which
were used to:



    - fund oil and gas prospect drilling, leasing and seismic data acquisition
      activities in the onshore Texas and Mississippi Gulf of Mexico region;



    - repayment of a portion of our outstanding debt; and


    - other working capital uses.


    In addition, we entered into a financing agreement with Shell Capital under
which we sold a term production payment to Shell Capital for $7.0 million.

SIX MONTHS ENDED JUNE 30, 1999 VS. SIX MONTHS ENDED JUNE 30, 1998



    NET LOSS.  For the six months ended June 30 , 1999, the Company reported a
net loss applicable to common stockholders of $4.6 million, or $0.13 per share,
compared to a net loss of $5.4 million, or $0.17 per share, in the comparable
1998 period. Weighted average shares outstanding increased from approximately
31.7 million in the first half of 1998 to over 33.9 million in the comparable
1999 period as a result of the issuance of common stock as a dividend payment on
our preferred stock as well as the exercise of warrants and options in the
second half of 1998.



    REVENUE.  For the six months ended June 30, 1999, revenue from crude oil and
natural gas production increased 61% over the same period in 1998. Natural gas
contributed 84% and crude oil contributed 16% of total oil and gas production
revenue.



    GAS SALES.  Natural gas sales increased 51%, from $1.8 million for the six
months ended June 30, 1998 to approximately $2.8 million for the same period in
1999, due primarily to increased production compared to the prior year period.
The Howell 32-14 #1 well was completed in late February 1999 and contributed a
total of approximately $590,600 in natural gas revenue on average production of
1,799 Mcf/d during the first six months of 1999. Two exploratory wells also had
first sales in the first half of 1999. The BOE 16-12 #1 and the BOE 16-14 #1
wells averaged 611 Mcf/d and 490 Mcf/d, respectively, for the first half of 1999
for combined natural gas revenue of approximately $384,100. In addition, the KS
Byrd well averaged 3,630 Mcf/d for the six months ended June 30, 1999 compared
to 2,636 Mcf/d for the same period in 1998. This increase in average production
increased revenue by approximately $179,900. The favorable impact of increased
production was partially offset by a decline in the average realized price for
natural gas sales from $2.23 per Mcf in the first half of 1998 to $1.82 per Mcf
in the comparable 1999 period. If we had received the same pricing as in the
prior year period at current production levels, natural gas revenue would have
been higher by approximately $627,100.



    OIL SALES.  For the six months ended June 30, 1999, oil sales increased 141%
to $514,500, compared to $213,700 for the same period in 1998, due primarily to
sales of production from new wells drilled and completed. The BOE 16-12 #1 had
first oil sales totaling approximately $251,200 for the period reported on
average production of 110 Bopd. In addition, the Rau Allen and the BOE 16-14 #1
wells contributed combined revenue of approximately $112,800 on average net
production of 46 Bopd. Oil revenue was also impacted by improved average
realized prices. Our average realized price for sales of crude oil in the first
half of 1999 increased by $1.19 per barrel, or 10%, increasing revenue by
$41,000 compared to the same period in 1998.



    DEPRECIATION, DEPLETION AND AMORTIZATION.  Our depreciation, depletion and
amortization expense for the first half of 1999 totaled $2.2 million compared to
$1.1 million in the comparable period for 1998. Full cost DD&A totaled $2.0
million for the six months ended June 30, 1999 compared to $1.0 million for the
same period in 1998. The increase in DD&A is consistent with a higher
amortizable asset base and an increase in production for the 1999 period
compared to the prior year period. On an equivalent Mcf basis, full cost DD&A
increased $0.07 per mcfe, from $1.03 per mcfe for the six months ended June 30,
1998 to $1.10 per Mcfe in the comparable 1999 period. DD&A of other assets for
the first half of 1999 totaled $189,400, an increase of $58,600 over the
comparable period in 1998, due primarily to an increase in the related asset
base.



    OPERATING COSTS.  Operating costs, including lease operating expense and
production taxes, increased 39% from $346,600 in the first half of 1998 to
$482,600 for the same period in 1999. The increase was due primarily to
increased production from wells drilled or acquired since the prior year period.
For the six months ended June 30, 1999, LOE, excluding severance taxes, totaled
$441,600 compared to $298,500 for the comparable period in 1998. On an
equivalent Mcf basis, average LOE for the first quarter of 1999 decreased from
$0.32 per Mcfe in 1998 to $0.25 per Mcfe in the same 1999 period.


                                       14
<PAGE>

    GENERAL AND ADMINISTRATIVE EXPENSE.  General and administrative expense for
the six months ended June 30, 1999 decreased $1.5 million, or 47%, compared to
the same period in 1998. On an equivalent Mcf basis, general and administrative
costs declined 73% to $0.93 per Mcfe for the six months ended June 30, 1999
compared to $3.39 per Mcfe for the same period in 1998. The decrease in general
and administrative costs was due primarily to lower compensation expense
generated by staff reductions during the fourth quarter of 1998 and the first
quarter of 1999. These staff reductions, as well as salary reductions for
certain of the remaining employees, are expected to significantly reduce general
and administrative costs in 1999.



    INTEREST EXPENSE.  Interest expense for the six months ended June 30, 1999
totaled $1.9 million compared to $2.3 million in the comparable prior year
period. Average debt was approximately $61.0 million for the first half of 1999,
resulting in gross interest costs of $4.0 million. Other financing costs include
the amortization of discount and the amortization of the original issue discount
for the EnCap NPI totaling $156,000. Partially offsetting these costs was
capitalized interest of $2.3 million, which was based on the carrying value of
unproved properties. Financing costs also included amortization of debt issuance
costs totaling $1.0 million for the first half of 1999. For the first half of
1998, average debt was approximately $39.1 million, resulting in gross interest
costs of $2.1 million. Other financing costs included the amortization of the
original issue discount for the EnCap NPI of $871,500. Partially offsetting
these costs was capitalized interest of $705,100. Amortization of debt issuance
costs totaled $485,100 for the first half of 1998.



    OTHER.  Other income (expense) for the six months ended June 30, 1999
included losses on the sale of marketable securities totaling $148,100 and the
write-off of an investment in equipment for a loss of $182,300. These costs were
partially offset by interest income of $163,300. For the comparable period in
1998 other income included interest income of $319,400 slightly offset by losses
on the sale of marketable securities totaling $17,000.


YEAR ENDED DECEMBER 31, 1998 VS. YEAR ENDED DECEMBER 31, 1997


    NET LOSS.  For the year ended December 31, 1998, we reported a net loss
applicable to common stockholders of $11.9 million, or $0.37 per share, compared
to a net loss of $4.4 million, or $0.18 per share, in the comparable 1997
period. Weighted average shares outstanding increased from approximately 24.1
million in 1997 to over 32.4 million in 1998 as a result of the conversion and
exercise of warrants in late 1997 and the issuance of common stock to acquire
certain properties in 1998 and to pay interest and dividends on the Lasco
acquisition note and subsequent preferred shares.


    REVENUE.  For the year ended December 31, 1998, revenue from crude oil and
natural gas production increased 378% over the same period in 1997. Natural gas
contributed 91% and crude oil contributed 9% of total oil and gas production
revenue.


    GAS SALES.  Natural gas sales increased over 460%, from $804,700 for the
year ended December 31, 1997 to approximately $4.5 million for the same period
in 1998, as the impact of increased production more than offset the impact of
the decline in natural gas prices. Production for 1998 increased significantly
over the comparable prior year period due primarily to production from the
assets purchased in our recent acquisitions and production from the K. S. Byrd
Well. This increase in production improved revenue for 1998 by $4.8 million. The
average realized price for natural gas sales declined from $2.80 per Mcf in 1997
to $2.24 per Mcf in the comparable 1998 period, decreasing revenues by $1.1
million. Income in 1998 from hedging gains increased gas realizations by $0.18
per Mcf.


    OIL SALES.  For the year ended December 31, 1998, oil sales increased 91% to
$440,500, compared to $231,100 for the same period in 1997, due primarily to
sales of production for properties acquired in our recent acquisitions and
production from our Reedy Creek properties. This increase in production improved
revenue for 1998 by approximately $544,700. Our average realized price for sales
of crude oil in

                                       15
<PAGE>
1998 decreased by $8.25 per barrel, or 43%, decreasing revenue by $335,300
compared to the same period in 1997.


    DEPRECIATION, DEPLETION AND AMORTIZATION.  Our depreciation, depletion and
amortization expense for 1998 totaled $3.2 million compared to $854,100 in the
comparable period for 1997. Full cost DD&A totaled $2.8 million for the year
ended December 31, 1998 compared to $709,200 for the same period in 1997. The
increase in DD&A is consistent with the increased production for 1998 compared
to the prior year period. Included in DD&A for the year ended December 31, 1997
was $221,000 of non-cash charges attributable to a price-related reduction in
the book value of our oil and gas reserves. On an equivalent Mcf basis, full
cost DD&A decreased $0.71 per Mcfe, from $1.97 per Mcfe for the year ended
December 31, 1997 to $1.26 per Mcfe in the comparable 1998 period. DD&A of other
assets for 1998 totaled $305,700, an increase of $160,800 over the comparable
period in 1997 due primarily to an increase in the related asset base.



    OPERATING COSTS.  Operating costs, including lease operating expense and
production taxes, increased 763% from $111,500 in 1997 to $962,700 for the same
period in 1998. The increase was due primarily to increased production from
wells drilled or acquired since the prior year period. For the year ended
December 31, 1998, lease operating expense, excluding severance taxes, totaled
$860,200 compared to $86,500 for the comparable period in 1997. On an equivalent
Mcf basis, average lease operating expense for 1998 increased from $0.24 per
Mcfe in 1997 to $0.38 per Mcfe in 1998. This increase is primarily due to the
Lasco acquisition that comprised older, lower rate wells.



    GENERAL AND ADMINISTRATIVE EXPENSE.  General and administrative expense for
the year ended December 31, 1998 increased over $1.9 million, or 52%, compared
to the same period in 1997. On an equivalent Mcf basis, general and
administrative costs declined 76% to $2.56 per Mcfe for the year ended December
31, 1998 compared to $10.51 per Mcfe for the same period in 1997. The increase
in general and administrative costs was due primarily to higher compensation
expense generated by a larger staff. We began 1998 with 26 employees, increasing
to 37 employees during the year. Staff reductions during the fourth quarter of
1998 reduced total employees to 29 at year-end. Further staff reductions during
the first quarter of 1999 reduced total employees to 21 at March 31, 1999. These
staff reductions, as well as salary reductions for the majority of the remaining
employees, are expected to significantly reduce general and administrative costs
in 1999. The overall high level of general and administrative expenses in 1997
was due to the initial costs associated with creating and managing our extensive
capital program.



    INTEREST EXPENSE.  Interest expense for the year ended December 31, 1998
totaled $5.8 million compared to $689,219 in the comparable prior year period.
The increase was due primarily to the financing arrangements under the EnCap
credit facility entered into in December 1997 and interest on the $37.5 million
principal amount of 9% convertible debentures issued in March and April of 1998.
Average debt was approximately $44.6 million for 1998, resulting in gross
interest costs of $4.8 million. Other financing costs include the amortization
of the original issue discount for the EnCap NPI of $1.7 million and the
amortization of deferred loan and issuance costs of $1.2 million. Partially
offsetting these costs were capitalized interest of $1.9 million, which is based
on the carrying value of unproved properties.



    OTHER.  Other income (expense) for the year ended December 31, 1998 included
a charge of $1.0 million due to the termination of an employee recorded in
December 1998 to reflect settlement of his employment contract. The settlement
will be paid out through January 2001. Offsetting this expense was interest
income of $573,609 and gains on the sales of marketable securities totaling
$24,971. For the comparable period in 1997, interest income of $77,844 was
offset by losses on the sales of marketable securities totaling $86,824.

FOUR MONTHS ENDED DECEMBER 31, 1997 AND TEN MONTHS ENDED AUGUST 31, 1997

    NET LOSS.  We reported a net loss of $2,739,300, or $0.10 per share, for the
four months ended December 31, 1997 and $1,917,100 or $0.09 per share, for the
ten months ended August 31, 1997. Weighted average shares outstanding were 27.9
million for the four months ended December 31, 1997 and 21.9 million for the ten
months ended August 31, 1997.


    GAS SALES.  Natural gas sales for the four months ended December 31, 1997
and the ten months ended August 31, 1997 totaled $624,400 and $256,000,
respectively. Production averaged 1,833 Mcfd for the four-month period ended
December 31, 1997 at an average price of $2.79 per Mcf and 276 Mcfd for the ten-
month period ended August 31, 1997 at an average price of $3.05 per Mcf. The
K.S. Byrd Well began production in September 1997 and averaged 1,605 Mcfd for
the four months ended December 31, 1997.


    OIL SALES.  Our crude oil sales for the four months ended December 31, 1997
and the ten months ended August 31, 1997 totaled $83,500 and $188,200,
respectively. Production averaged 36.9 barrels per day and 30.5 barrels per day,
respectively, for the four-month period ended December 31, 1997 and the
ten-month period ended August 31, 1997. Our average realized price for sales of
crude oil for the four-month period ended December 31, 1997 and the ten-month
period ended August 31, 1997 were $18.54 per barrel and $20.28 per barrel,
respectively.


    DEPRECIATION, DEPLETION AND AMORTIZATION.  For the four months ended
December 31, 1997, depreciation, depletion and amortization expense totaled
$634,500 and for the ten months ended August 31, 1997, DD&A expense was
$240,400. Full cost DD&A averaged $2.32 per Mcfe for the four months ended
December 31, 1997 and $1.07 per Mcfe for the ten months ended August 31, 1997,
due primarily to a ceiling test write-down of $221,000 at December 31, 1997.



    OPERATING COSTS.  Operating costs totaled $49,800 and $68,500, respectively,
for the four-month period ended December 31, 1997 and the ten-month period ended
August 31, 1997. Lease operating expense, excluding severance taxes, totaled
$42,700 and $45,600 for the same periods, respectively. On an equivalent barrel
basis, LOE for the four months ended December 31, 1997 averaged $0.17 per Mcfe
and for the ten months ended August 31, 1997 averaged $0.33 per Mcfe.



    GENERAL AND ADMINISTRATIVE EXPENSE.  General and administrative costs
totaled $2,087,100 for the four months ended December 31, 1997 and $2,026,400
for the ten months ended August 31, 1997. On an equivalent Mcf basis, general
and administrative expenses were $8.32 per Mcfe for the four months ended
December 31, 1997 and $14.53 per Mcfe for the ten months ended August 31, 1997.
General and administrative costs were significant during these periods and
reflected establishment of the infrastructure necessary to sustain the planned
expansion of our oil and gas operations and our desired position as operator of
many of our prospects. Costs included signing bonuses paid to professional and
senior management staff as inducements to leave their previous employment and
join us, legal and accounting fees, and the settlement of a lawsuit filed by a
former employee.



    NET FINANCING COSTS.  Net financing costs for the four months ended December
31, 1997 were $625,100, and consisted of gross interest expense of $286,700, the
amortization of the original issue discount for the EnCap NPI of $427,500 and
amortization of deferred loan costs of $42,900. Partially offsetting these costs
was capitalized interest of $108,200 and interest income of $23,800. For the
ten-months ended August 31, 1997, gross interest expense of $49,300 was more
than offset by interest income of $59,200. The higher financing costs in the
four-month period ended December 31, 1997 reflect our increase in long-term debt
from $759,300 at August 31, 1997 to $14.7 million at December 31, 1997. This
increase in debt relates to the EnCap credit facility entered into in late 1997,
that was used to finance the Oakvale Dome Field and Old Ocean acquisitions and
related development.

    OTHER.  Other revenue for the four-month period ended December 31, 1997 and
the ten-month period ended August 31, 1997 represents losses on the sale of
marketable securities of $50,900 and $35,900, respectively.

LIQUIDITY AND CAPITAL RESOURCES


    Our primary cash needs are for exploration, development and acquisition of
oil and gas properties, the repayment of trade payables and repayment of
principal and interest on outstanding debt. Our sources of financing include
sales of securities, revenue generated from operations, ongoing sales of
non-core assets and proceeds from production payment facilities. Based on the
foregoing, we will require additional capital from more than one of the sources
identified above to fund our ongoing activities and capital budget. If we are
unable to obtain additional capital, we will either have to sell interests in
our prospects to fund our drilling program, curtail our exploration activities
or curtail ongoing activities. The curtailing of activities could include
reducing the number of wells drilled, slowing activities on projects that we
operate, selling additional interests in our prospect inventory or a combination
of these alternatives.



    Many of the factors that may affect our future operating performance and
long-term liquidity are beyond our control, including, but not limited to:



    - oil and natural gas prices;



    - governmental actions and taxes;



    - the availability and attractiveness of financing; and


    - our operational results.


    We continue to examine alternative sources of long-term capital, including:



    - bank borrowings;



    - the issuance of debt instruments;



    - the sale of common stock or other equity securities;



    - the issuance of net profits interests;



    - sales of promoted interests in our prospects; and


    - various forms of joint venture financing.

    In addition, the prices we receive for our future oil and natural
gas-production and the level of our production will have a significant impact on
future operating cash flows.


    LIQUIDITY.  At June 30, 1999, we had cash and cash equivalents on hand of
$29,100 and working capital deficit of $41.2 million, as compared to a cash
balance of $2.3 million and a working capital deficit of $27.5 million as at
December 31, 1998 and a cash balance of $3.2 million and a working capital
deficit of $15.3 million at December 31, 1997. Our ratio of current assets to
current liabilities was 0.13:1 at June 30, 1999, 0.25:1 at December 31, 1998 and
0.37:1 at December 31, 1997. The working capital deficit and low current ratio
were primarily due to the maturity dates of the EnCap credit facility and BOCP
credit facility discussed below, repayment of which was made in August 1999.



    CASH FLOWS.  Cash flows provided by operations totaled $153,600 for the six
months ended June 30, 1999, compared to cash flows used in operations of $4.1
million for the year ended December 31, 1998. Cash used in investing activities
for the six months ended June 30, 1999 and year ended December 31, 1998 was $9.3
million and $35.4 million, respectively. During the first half of 1999, costs
incurred for exploration and development expenditures totaled $10.0 million and
capital expenditures for furniture and equipment totaled $65,700. Partially
offsetting these costs were proceeds of $160,500 from the sale of marketable
securities and $534,700 in proceeds from the sale of non-core oil and gas
properties. Cash outlays for


                                       18
<PAGE>
exploration and development expenditures totaled approximately $36.3 million and
capital expenditures for furniture and equipment totaled $745,400 during the
year ended December 31, 1998. Partially offsetting these costs were $1.1 million
in proceeds from the sale of non-core properties and $1.1 million in proceeds
from the sale of marketable securities.


    Cash provided by financing activities totaled $3.0 million for the first
half of 1999 and included borrowings under the BOCP credit facility of
approximately $3.0 million and repayments under the Shell production payment
totaling approximately $550,200. For the year ended December 31, 1998 cash
provided by financing activities totaled approximately $38.7 million and
consisted primarily of proceeds from the issuance of 9% convertible debentures
and 9% notes. We also borrowed $3.0 million under the EnCap credit facility and
repaid $5.0 million thereunder during the first quarter of 1998. In December
1998, we entered into a financing agreement with Shell Capital under which we
sold a term production payment to Shell Capital for $7.0 million. Also in
December, we repaid $2.9 million on Tranche A and Tranche B loans under our BOCP
credit facility resulting in net borrowings under that facility of $2.3 million
for the year ended December 31, 1998. We also borrowed $2.2 million for the
acquisition of property interests from Mobil through the Old Ocean loan.


CREDIT FACILITIES


    ENCAP CREDIT FACILITY.  In 1997, we entered into a $20 million credit
agreement with EnCap Capital Fund III, L.P. consisting of an original promissory
note for $12 million and a supplemental promissory note for $8 million. The
original note bears interest at 10% per annum through December 31, 1998 and at
18% per annum thereafter. The original and supplemental note were repaid in full
and are no longer outstanding. The proceeds from the facility were applied to
the acquisition of Oakvale Dome ($8,000,000), and Old Ocean properties and the
drilling and completion of certain development wells ($4,000,000). A first lien
on certain properties and a second lien on certain other properties secure the
original note. Mr. Tomlinson, Calibre and certain affiliates of Calibre
guarantee the original note.


    Under the terms of the original note, we agreed to convey to EnCap Energy,
on January 1, 1999, a 25% net profit interest from the properties acquired with
the proceeds of the borrowing. In connection with the original granting of the
EnCap NPI, we recorded a discount on the original note of $2,102,180 as of
December 31, 1997. The discount has been amortized over the term of the original
note. The carrying amount of the oil and gas interests has been reduced by the
same amount.

    Under the terms of the supplemental note, EnCap Energy was issued warrants
to purchase up to 1.5 million shares of our common stock at an exercise price of
$1.28 per share. In connection with the issuance of these warrants, we recorded
a discount on the supplemental note of $367,881 as of December 31, 1997. This
discount is being amortized over the term of the supplemental note. Pursuant to
a financing agreement dated November 4, 1998 with EnCap Energy and as
consideration for enabling additional funding through the BOCP Credit Facility,
the warrants were re-priced to $0.46475 per share.

    BOCP CREDIT FACILITY.  In December 1998, our loan agreement with Bank One NA
was purchased by BOCP Energy Partners, L.P., an affiliate of EnCap. Pursuant to
an assignment of note and liens dated December 29, 1998, Bank One assigned the
original loan agreement, together with all loan documents referred to therein,
to BOCP. In December 1998, the principal amount then outstanding under Tranche A
of $2.9 million plus interest was repaid and, per amendments to the loan
agreement, no further advances will be requested or made under Tranche A.
Interest accrued on Tranche A at prime plus 2.0% and on Tranche B at a rate of
15% per annum, payable monthly.

    The amendments also modified the terms of Tranche B of the credit facility
as follows:

       - Maximum availability of $6,000,000;

       - No advances on Tranche B will be requested or made on or after April
         30, 1999;

                                       19
<PAGE>
       - Maturity date of July 31, 1999; and

       - Interest rate of prime plus 8% per annum through and including December
         31, 1998, and 15% per annum from and after January 1, 1999.


    The present outstanding balance of the BOCP credit facility of $6.0 million
plus all accrued interest was repaid in full in August 1999.


    SHELL FINANCING.  In December 1998, we entered into a financing agreement
with Shell Capital, Inc. whereby we sold a term production payment to Shell
Capital for $7.0 million. The production payment comprised a dedication of 42%
of the net revenues from the Wausau, Oak Hill and East Morgantown properties,
23.1% of Oakvale Dome's Howell well, 12.2% of Oakvale Dome's Fortenberry well
and 38.5% of Oakvale Dome's Byrd well. The interests conveyed are subject to
future adjustment. The Shell production payment is secured solely by the
properties and is non-recourse to us. Following full pay-out ($7.0 million plus
a 15% rate of return) of the production payment, the dedicated revenue interest
is returned to us less a permanent royalty interest equal to 8.75% of our net
revenue interest in Wausau, Oak Hill and East Morgantown; 4.8% of the Howell and
Byrd wells; and 2.5% of the Fortenberry well. We have the right to buy back the
production payment at a stated rate of return of 25% plus a payment of $1.0
million. In connection with the right to buy back the permanent overriding
royalty interest conveyance, we recorded a discount on the financing of $1.0
million. The carrying amount of the oil and gas interests has been reduced by
the same amount. Shell Capital further agreed to expand the Shell production
payment up to $25.0 million provided that we sell certain properties, enter into
a payment schedule for amounts owed to an industry partner, raise additional
capital and obtain certain minimum results from current development drilling
activity. We are currently negotiating with Shell Capital and other parties to
complete the expansion of the Shell production payment or the creation of a new
production payment.

    This financing has been classified as debt on the balance sheet and began
being reduced in 1999 as production is delivered to Shell under the terms of the
contract. Volumes delivered to Shell are reported as revenue at prices received
by Shell. Interest expense is recorded based on a rate of 15% per annum.


    OLD OCEAN LOAN.  On December 31, 1998, we obtained a $2.2 million loan from
a group of lenders led by RP&C International, the Agent in our recently
completed offering of convertible preferred stock, the proceeds being used to
acquire additional interests in the Old Ocean Project from Mobil. The loan was
due, through extension, on July 31, 1999, and was secured by the acquired
interests and a junior lien on certain other properties. We have repaid a
majority of the loan through the issuance of our convertible preferred stock in
July 1999. We also granted the providers of the facility with an overriding
royalty that is to be converted into a participating net profit interest, which
interest can be repurchased by us for $1.1 million in cash or stock and $1.1
million principal amount of warrants. We repurchased the overriding interest and
participating net profits interest with preferred stock as well. One lender of
$100,000 elected to accept cash for repayment of their portion of the loan and
purchase of the overriding interest and was paid in July 1999.


CONVERTIBLE DEBENTURES

    In April 1998, we issued to certain Canadian investors $1,652,000 principal
amount of our series A special notes, which are convertible into the same
principal amount of our series 2 debentures, and issued to certain United States
investors $6,960,000 principal amount of our series 3 debentures on
substantially similar terms as the series A notes. We intend to offer holders of
the series 3 debentures the ability to exchange their special notes or
debentures into class A, series II preferred stock on terms no more favorable
than the terms on which we recently completed the exchange of our 9% convertible
debentures, series I due March 31, 2003. The holders of series 2 debentures will
not be offered the opportunity to exchange their series 2 debentures for
preferred stock.

                                       20
<PAGE>
CHANGES IN ISSUED SHARE CAPITAL

    On May 28, 1999, we issued 1,057,500 shares of our common stock to certain
holders of our series 3 debentures in exchange for interest owed and due on
March 31, 1999. We also agreed to issue 541,700 shares of our common stock to a
holder of series 3 debentures to retire a $250,000 principal amount of the
debentures.

YEAR 2000

    We operate on an externally designed software package that is compliant with
the year 2000. The year 2000 problem is the result of software that uses two
digits (rather than four) to define the applicable year. Any software or
hardware that uses time-sensitive coding may recognize a day using "00" as the
year 1900 rather than the year 2000, which could result in miscalculations or
system failures. We are attempting to identify other potential areas of risk and
have begun addressing these in our planning, purchasing and daily operations.
Based on preliminary information, costs of addressing potential problems are not
currently expected to have a material adverse impact on our financial position,
results of operations, or cash flows in future periods. If, however, we, our
customers, or vendors are unable to adequately resolve such processing issues in
a timely manner, our operations and financial results may be adversely affected.

                            BUSINESS AND PROPERTIES

BACKGROUND


    We are an independent energy company engaged in the exploration for and
development of oil and natural gas. We have interests in over 25 oil and gas
prospects and projects primarily in the United States Gulf Coast areas of
Mississippi, Texas and Louisiana. Most of these prospects have been, are being,
or are expected to be, enhanced with 3-D seismic data and CAEX technologies. The
3-D seismic data, when completed, will cover over 820 square miles. Our 1999
capital budget provides for a total of $11.3 million for drilling and prospect
development. Of this amount:



    - approximately $7.3 million is budgeted for development drilling;



    - approximately $1.0 million is budgeted for exploratory drilling, testing
      and subsequent completions;



    - $2.3 million is budgeted for net seismic data acquisitions; and


    - the remainder is budgeted primarily for leasehold purchases.


    We were originally formed on February 9, 1981, for the purpose of conducting
mineral exploration in Canada. In 1989, we changed our focus and concentrated on
investment and merchant banking activities. At that time, we wrote off our
mineral property costs and ceased all mineral exploration activities. From 1991
to 1993, we diversified into the acquisition and development of oil and gas
properties. During 1996, we sold substantially all of our investments outside of
oil and gas and refocused operations on oil and gas exploration and development
in the United States. Effective as of October 31, 1996, we acquired Texstar
Petroleum, Inc., and as a result, we focused our operations on oil and gas
exploration and development in the United States, specifically the Gulf Coast
areas of Mississippi, Texas and Louisiana. Former shareholders of Texstar
acquired our control, and Texstar became our wholly owned subsidiary. In July
1997, we changed our name from Benz Equities Ltd. to Benz Energy Ltd. We have
reincorporated in Delaware and are now a Delaware corporation under the name
Benz Energy Inc.


    A substantial portion of our growth has been through acquisitions, including
the following 1998 acquisitions:


    - the acquisition in January 1998 of certain oil and gas prospects from
      Lasco Energy Partners, L.P.;


    - the acquisition on April 22, 1998 of certain oil and gas property
      interests of Calibre (certain closing matters to be completed);

    - the acquisition on May 1, 1998 of certain oil and gas properties from
      Southern Gas Corporation;

    - the acquisition effective in July 1998 of certain oil and gas property
      interests from Starbucks Trust (certain closing matters to be completed);
      and

    - the acquisition on December 29, 1998 of the Mobil interest in the Old
      Ocean project.

RECENT DEVELOPMENTS


    On August 25, 1999, we sold 37.5% of our interest in the Old Ocean Prospect
to Prime Natural Resources, Inc. Prime paid us $3,500,000 at closing and will
pay an additional $1,978,098 on or before September 15 in consideration of the
interest purchased. We reserved an overriding royalty interest in all leases and
contractual rights to volumes of production and all similar interests, whether
we currently own them or later acquire them, within the established area of
mutual interest for the project. Prime has an option for a six month period to
purchase an additional 12.5% of our interest in the Old Ocean prospect, subject
to the overriding royalty reservation set forth above, at a purchase price of
$1,826,033, plus $214,276 at the end of the six month period. We have agreed to
enter into an agreement under which Prime or one of its affiliates will have the
right to market the 3-D seismic geophysical data covering the Old Ocean Prospect
for a ten year period following a 120 day exclusivity period that we have
retained. Prime


                                       22
<PAGE>

will be entitled to our share of the proceeds from the sale of the data, which
share may be no less than 66 2/3%, subject to applicable sales commissions. In
addition, Prime or its affiliate must grant us a license to other geophysical
data outside the Old Ocean prospect owned by Prime or its affiliate. We may
select the outside data of our choice covering up to 102 square miles.



    Also in August 1999, we completed a new, long-term production financing with
Aquila Energy Capital Corporation in the amount of $26.2 million. This amount
may be increased to $27.7 million based on near term production results in our
Fortenberry well. The new facility also provides for the lender to fund
additional development drilling at our Oakvale Dome field in Mississippi to a
maximum of $3.8 million. The new production financing is secured by our proven
oil and gas properties and is to be repaid through a dedicated portion of the
property income. Terms of the financing include a 12% interest rate and
assignment of 1/16th of our interest in the proven properties following full
repayment of the new production financing. Proceeds from the financing were used
to retire existing senior secured debt.



    August activity also included a private placement of $4 million in new
equity through the issuance of $4.4 million of redeemable class A preferred
stock, series I to investment entities affiliated and managed by EnCap
Investments, L.C. We paid a placement fee of $100,000 to EnCap Investments, L.C.
Proceeds were used to fund arrangements under the trade creditor agreement
described above and for general corporate purposes.



    On July 12, 1999, we conducted a meeting with our trade creditors to outline
a proposed repayment plan for past due amounts. The plan included proposed
discounts, payment over an extended time and other revised payment terms. As of
September 8, 1999, creditors representing 93% of past due amounts, for an
aggregate of $11.3 million, elected to participate in the repayment plan.



    On July 9, 1999, we consummated an offering pursuant to which we offered to
exchange up to 354,250 shares of our class A, series II convertible preferred
stock for any and all of our outstanding 9% convertible debentures, series I,
due March 31, 2003, and an offering to sell up to 121,000 shares of class A,
series II convertible preferred stock. At the closing, we exchanged $15,145,000
principal amount of the 9% convertible debentures and issued an aggregate of
238,201 shares of class A, series II convertible preferred stock, which included
44,600 shares issued under the primary offering and the remainder of which were
issued pursuant to the exchange offer. In addition, we issued 34,596 shares of
class A, series II convertible preferred stock and warrants to purchase
3,974,923 shares of common stock in connection with the retirement of a majority
of the Old Ocean loan. The proceeds from the exchange offer and offering of
convertible preferred stock were used to retire the Old Ocean loan, to
repurchase EnCap's portion of the Old Ocean NPI, the payment of a portion of the
seismic costs relating to the Old Ocean prospect, and for the fees and expenses
of the transactions.



    In June 1999, we completed the drilling of our Fortenberry #1 well to a
depth of 16,126 feet at Oakvale Dome Field in Jefferson Davis County,
Mississippi. We elected to not drill deeper to the projected depth of 16,250
feet due to concerns that additional drilling difficulty could be encountered in
the sidetrack hole. Open hole electric and porosity logs which run to a depth of
16,088 feet indicate a total of 80 net feet of hydrocarbon bearing sands in the
primary objectives in the Hosston Formation at depths between 15,792 feet and
15,992 feet. An additional four feet of net pay was measured by electric and
porosity logs in the lower Booth zone starting at a depth of 16,075 feet based
on mud logs from the original sidetrack hole. The remainder of the zone could
not be logged due to existing hole conditions. We own a 70% working interest in
the well and an average 64% working interest in the field. We are proceeding to
complete the well for production.



    In May 1999, we closed the sale of our interests in the Lisbon Field,
comprising essentially all of our proven reserves in Louisiana, for $507,500 in
gross proceeds to an unrelated party.



    In January 1999, we acquired, on behalf of us and our partner in the Wausau
prospect, a gas pipeline in Mississippi for approximately $425,000 to provide
access for gas sales. Included in the purchase were a


                                       23
<PAGE>

100% and a 93.75% Bpo working interest in two producing gas wells. We own a
53.8% interest in the pipeline and the Fairchild #1 well and a 50.5% interest in
the A. Foote Estate #1 well. Gas reserves net to us are estimated to be in
excess of 150 Mmcfg and net production of over 150 Mcfgpd.


STRATEGY

    Our strategy is to expand our reserves, production and cash flow through the
implementation of an exploration and exploitation program that focuses on:

    - obtaining dominant positions in core areas of exploration and development
      in under-exploited areas in or adjacent to fields and trends that have
      historically produced hydrocarbons in significant quantities;

    - enhancing the value of our prospects and reducing exploration risks
      through the use of 3-D seismic data and CAEX technologies;

    - maintaining an experienced technical staff with the expertise necessary to
      take advantage of our proprietary 3-D seismic data and CAEX technologies;

    - adding reserves and production using modern reservoir stimulation methods;
      and

    - retaining control over critical exploration decisions.


    OBTAIN DOMINANT POSITION IN CORE AREAS.  We have identified core areas for
exploration and development in geological trends with demonstrated histories of
prolific natural gas production from high porosity reservoir rocks with profiles
suitable for seismic evaluation. We believe that by obtaining substantial
working interests, related 3-D seismic data and significant acreage positions
within our core areas, we will be able to achieve a dominant position in focused
portions of those areas. With a dominant leasehold position, we believe we can
better control the core areas, drilling opportunities and future production and
can attempt to minimize costs through economies of scale and other efficiencies
inherent in our focused approach. These cost savings and efficiencies include
the ability to use our 3-D seismic data to reduce drilling risks and lower our
leasehold acquisition costs by identifying and purchasing leasehold interests
only in those focused areas in which we believe drilling is most likely to be
successful.



    USE OF 3-D SEISMIC AND CAEX TECHNOLOGIES.  We attempt to enhance the value
of our prospects through the use of 3-D seismic data and CAEX technologies, with
an emphasis on direct hydrocarbon detection technologies. These technologies
create a computer generated 3-dimensional display of subsurface geological
formations that help our professional staff detect seismic anomalies in
structural features that are not apparent in 2-D seismic surveys. We believe
that 3-D seismic data, if properly used, will reduce drilling risks and costs by
reducing the number of dry holes, optimizing well locations and reducing the
number of wells required to exploit a discovery.



    EXPERIENCED TEAM.  We maintain an experienced staff, including engineers,
geoscientists, landmen and other technical personnel. Our professional staff has
on average 18 years of experience in the oil and gas industry.


    USE OF MODERN RESERVOIR STIMULATION METHODS AND NEW DRILLING TECHNOLOGY.  In
addition to applying the latest in 3-D seismic and CAEX technology, we use the
latest in industry reservoir stimulation and directional drilling techniques.
For example, many of our development and exploitation opportunities are "tight"
reservoirs in which modern stimulation practices may significantly increase
production.

    CONTROL OF DRILLING FUNCTIONS.  We believe that controlling the most
critical functions in the drilling process will enhance our ability to
successfully develop our prospects. We have acquired a majority interest in many
of our prospects, including interests in most of the 3-D seismic data relating
to those prospects. In many cases where we do not own a majority interest in a
prospect we still own a greater interest than that of any other working interest
owner. As a result, in many of our prospects, we will be able to influence the

                                       24
<PAGE>
areas to explore, manage the land permitting and option process, determine
seismic survey areas, oversee data acquisition and processing, prepare,
integrate and interpret the data and identify each prospect drillsite. In
addition, we will be the operator of many of the wells drilled on these
prospects.

THE PROSPECTS


    Our prospects are located primarily in the Gulf Coast areas of Mississippi,
Texas and Louisiana. As of June 30, 1999, we owned interests in 12 producing
wells we operated and also owned non-operated interests in 13 producing wells.
Daily production from both operated and non-operated wells net to our interest
averaged 5,506 Mcfgd and 111.4 Bopd for the year ended December 31, 1998, and
8,494 Mcfgd and 226 Bopd for the six months ended June 30, 1999. Daily
production as of June 30, 1999, was approximately 9,324 Mcfgd and 137 Bopd.


                                       25
<PAGE>

    Each of our prospects differs in scope and character and consists of one or
more types of assets, such as 3-D seismic data, working interests in oil and gas
leases, oil and gas lease options, contractual rights to earn a working interest
in oil and gas leases, royalty interests or other mineral interests. Most of our
prospects have been, are being, or are expected to be enhanced with 3-D seismic
data and CAEX technologies. The 3-D seismic data acquired will, when completed
for the existing prospects, cover over 820 square miles. The table below gives
certain information regarding the location, objectives, and present status of
our most significant prospects as of June 30, 1999:

    Set forth below are descriptions of our most significant prospects. Unless
otherwise indicated, all information is as of June 30, 1999.



    OAKVALE DOME.  The Oakvale Dome prospect, located in Jefferson Davis County,
Mississippi, is our most significant producing property. We own approximately
4,717 gross (2,097 net) acres in the prospect. We are the operator.



    A 2-D seismic survey shot and processed originally in 1979, was reprocessed
in 1996 and confirmed the discovery well, which was the K.S. Byrd Well. The K.S.
Byrd Well was completed in June 1997 in the Harper formation from 15,964 feet to
15,988 feet, flowing 5.708 Mmcfgd. Initial reserve estimates as of August 1,
1997 conducted by an independent petroleum engineer gave the well proved
producing reserves of 8.7 Bcfg and 34,800 barrels of condensate. Later reserve
estimates as of January 1, 1999 conducted by an independent petroleum engineer
revised the well's proved producing reserves to 12.1 BCFG and 41,500 barrels of
condensate. The well began sales of production in September 1997 and, as of June
30, 1999, was flowing at the rate of 6,757 Mmcfgd and 21 Bopd.



    In February of 1999 the Howell #1 well was completed and initial tests
indicate a commercial production rate of 21.1 Mmcfgd and 19 barrels of
condensate per day.


    The Fortenberry #1 has just been drilled to total depth. The well is being
completed for production.


    GLANCY.  We own approximately 5,175 gross (4,730 net) acres in the Glancy
prospect in Copiah County, Mississippi. We are the operator. Glancy Field has
produced gas and condensate from the Lower Cretaceous Rodessa formation on
acreage not owned by us. The Glancy prospect is characterized as a simple
anticline structure that formed as a result of a deep-seated salt pillow. The
presence of reservoir quality sandstones at both the deeper Hosston and Cotton
Valley levels has been demonstrated by two well penetrations, both of which have
produced gas and had multiple shows of hydrocarbons. Early attempts (in 1971) to
fracture stimulated one of the test wells, having an initial production of 3.1
Mmcfgd on an extended test from the Cotton Valley, damaged the formation in the
near-wellbore area. We intend to reenter a deep test well and to apply modern
fracture stimulation to establish commercial production.



    WAUSAU.  We own approximately 960 gross (483 net) acres in the Wausau
prospect in Wayne County, Mississippi (surface to 15,360 feet only). We are the
operator. We have rights in a 3-D survey acquired by Compagnie Generale de
Geophysiqe over this prospect area. This project is located on two flanks of a
large salt ridge trending northwest to southeast. Based upon 3-D seismic data,
the Cotton Valley appears to be trapped in both a simple closure and an updip
pinchout along the salt ridge flank. We commenced


                                       27
<PAGE>

drilling a test well in May 1998 and completed the well in November 1998 as a
Cotton Valley discovery. Production commenced in November 1998 and was increased
to a rate of over 400 Bopd and 2,000 Mcfd with the connection to a gas sales
pipeline in February 1999. The well has three additional shallower Cotton Valley
reservoirs behind pipe.



    SARDIS CHURCH DOME.  We own approximately 3,508 gross (3,038 net) acres in
the Sardis Church Dome prospect in Copiah County, Mississippi. We are the
operators. Our drilling objectives are the Paluxy, Hosston and Cotton Valley
sands. We anticipate we will sell at least 50% of the working interest to an
industry participant before spudding the test well. This prospect is an analog
to the Oakvale Dome discovery and is located along a trend. A nearby off
structure well has tested significant oil and gas shows in the Hosston objective
section.



    LAHINCH.  We own deep rights under approximately 1,382 gross ( 1,036 net)
acres in the LaHinch prospect in Duval County, Texas. We are the operator. The
objectives for the prospect are sands in the Upper Wilcox formation. The
adjoining operator has drilled an Upper Wilcox test on the same structure that,
if successful, will confirm our prospect and reclassify it as a proven location.
This well reached total depth in April 1999 and is currently being completed.



    OLD OCEAN.  We own leases, options for oil and gas leases and have
contractual rights to earn working interests in approximately 17,189 gross
(8,789 net) acres in the Old Ocean prospect in Brazoria and Matagorda Counties,
Texas. We own a 37.02% working interest within the Old Ocean unit and a 69.23%
working interest outside the unit, but within the 3-D area. A 3-D seismic survey
is underway and we are the operator. The Old Ocean prospect is the largest Frio
gas field in the Gulf Coast, having produced more than five Tcfge since its
discovery in 1934. In excess of 200 wells have been drilled in the Old Ocean
field. These reserves have been produced from four normally pressured reservoirs
between 9,500 and 11,000 feet.



    The Old Ocean prospect actually consists of numerous prospects. The main
objective is in the over pressured Frio. Deep well information confirms
reservoir quality sands and scattered production of 45 BCFG in the immediate
vicinity. Precise structural mapping from the 3-D seismic survey will allow
accurate delineation of prospects.



    OAK HILL FIELD.  We own approximately 793 gross (698 net) acres in the Oak
Hill field in Gregg and Rusk Counties, Texas. We are the operator. This prospect
produces from the Lower Cotton Valley sands at depths of approximately 10,150 to
10,500 feet and from the Upper Cotton Valley sands at depths of approximately
9,000 to 10,000 feet. We have completed a recompletion program covering six
wells and involving up to eleven distinct zones. Six recompleted zones have been
fracture stimulated and have increased our net production by over 1,100 Mcfd.
Additionally, we expect an increase of approximately 800 Mcfd net production
when the original producing interval is reactivated and the pressures across the
zones equalize. We currently own interests in six producing wells in Oak Hill
field.



    RAYBURN.  We own approximately 2,966 gross (1,298 net) acres and have
options for oil and gas leases on an additional 1,070 gross (847 net) acres in
the Rayburn prospect in Liberty Co., Texas. We are the operator. This prospect
is within a 30 square mile 3-D survey we acquired in 1998, of which we intend to
sell up to 60% to industry partners. The objectives are sands primarily in the
Wilcox, Cockfield and Miocene formations ranging in depth from 2,000 to 16,000
feet.

    generated from the production of proved reserves, net of estimated
    production and future development costs, using prices and costs in effect as
    of January 1, 1999. The amounts shown do not give effect to expenses
    unrelated to property, such as general and administrative expenses, debt
    service and future income tax expense or to depreciation, depletion and
    amortization. The estimates shown do not include amounts dedicated to Shell
    Capital pursuant to the Shell Production Payment, but do include the effect
    of the EnCap NPI which vested on January 1, 1999. The EnCap NPI comprises a
    6.25% interest in the producing Byrd #1 and Howell #1 wells.



(3) "Proved developed reserves" means those reserves estimated as recoverable
    under current technology and projected economic conditions, from that
    portion of a reservoir that can reasonably be evaluated as economically
    productive on the basis of analysis of drilling, geological, geophysical and
    to be obtained by enhanced recovery processes demonstrated to be economic
    and technically successful in the subject reservoir.



(4) "Proved undeveloped reserves" means those reserves estimated as recoverable
    under current technology and projected economic conditions from that portion
    of a reservoir that can reasonably be evaluated as technologically
    productive, but which requires the drilling and completion of a well to
    initiate production.


(5) In May 1999, we sold our interest in the Lisbon Field, which accounted for
    all of the proved developed and undeveloped reserves in Louisiana.

ACREAGE


    The following table sets forth as of June 30, 1999, the gross and net acres
of developed and undeveloped oil and gas acreage that we hold. Additionally, the
data set forth below is based on our before pay-out working interests. In
certain cases, we have a greater after pay-out working interest. In certain
other cases, we have only an after pay-out working interest. As such, the amount
of gross and net acreage will increase when and if certain wells pay out.

DRILLING ACTIVITY


    During the first two quarters of 1999, we participated in one gross (.140600
net) productive exploratory well one gross (.556248 net) productive
developmental well and one gross (.1575 net) dry developmental well. We
participated in one gross (0.14 net) dry and three gross (1.8383 net) productive
exploratory wells and three Gross (0.25954 net) productive development wells
during the year ended December 31, 1998. For the four-month period ended
December 31, 1997, we drilled one gross (0.48500 net) productive exploratory
well, two gross (1.3575 net) dry exploratory wells and three gross (0.342202
net) productive development wells. For the ten months ended August 31, 1997, we
drilled one gross (0.14725 net) productive exploratory well and one gross
(0.20110 net) dry exploratory well. We are entitled to a working interest in
certain additional wells completed during these time periods when and if those
wells pay-out. Furthermore, the number of net wells was calculated based-on our
before pay-out working interest and in some cases we will have a greater working
interest or is entitled to a working interest in certain wells completed during
these time periods when and if these wells pay-out. In certain cases, we,
subsequent to completion, sold the prospect on which certain of these wells were
drilled. As such, while we did participate in the drilling, it does not
currently have an interest in all of the productive wells mentioned above.



    On June 30, 1999, we were drilling one gross (0.704075 net) development well
and one gross (0.140000 net) exploratory well.

CAEX AND 3-D SEISMIC TECHNOLOGY


    We, either directly or through other prospect participants, use 3-D seismic
data and CAEX technology to collect and analyze geological, geophysical,
engineering, production and other data obtained about potential gas or oil
prospects. We use this technology to correlate density and sonic characteristics
of subsurface formations obtained from 2-D seismic surveys with like data from
similar properties, and use computer programs and modeling techniques to
determine the likely geological composition of a prospect and potential
locations of hydrocarbons.


                                       31
<PAGE>

    Once all available data have been analyzed to determine the areas with the
highest potential within a prospect area, we may conduct 3-D seismic surveys to
enhance and verify the geological interpretation of the structure, including our
location and potential size. The 3-D seismic process produces a three-
dimensional image based upon seismic data obtained from multiple horizontal and
vertical points within a geological formation. The calculations needed to
process these data are made possible by computer programs and advanced computer
hardware.



    While large oil companies have used 3-D seismic data and CAEX technologies
for approximately 20 years, these methods were not affordable by smaller,
independent oil and gas companies until more recently, when improved data
acquisition equipment and techniques and computer technology became available at
reduced costs. We believe that our use of 3-D seismic data and CAEX technology
may provide us with certain advantages in the exploration process over those
companies that do not use these technologies. These advantages include better
delineation of the subsurface, which can reduce exploration risks and help
optimize well locations in productive reservoirs. We believe these advantages
can be readily validated based upon general industry experience. Because
computer modeling generally provides clearer and more accurate projected images
of geological formations, we believe it is better able to identify potential
locations of hydrocarbon accumulations and the desirable locations for
wellbores. However, we have not used the technology extensively enough to arrive
at any conclusion regarding our ability to interpret and use the information
developed from the technology.


CUSTOMERS


    For the six months ended June 30, 1999, Coral Energy L.P., EOTT Energy
Operating Limited Partnership, and Tejas Gas Corporation accounted for
approximately 66%, 11% and 10%, respectively, of our total oil and gas revenue.
During the year ended December 31, 1998, H&N Gas Ltd. and Tejas Gas Marketing
Co. accounted for approximately 51% and 24%, respectively of our total revenue.
For the four-month period ended December 31, 1997, H&N Gas and KCS Resources,
Inc. accounted for 75% and 10%, respectively, of our total revenue. For the ten
months ended August 31, 1997, KCS, Samedan Oil Corporation and Energy Operating
Limited Partnership accounted for 50%, 30% and 15%, respectively, of our total
revenue. No other purchasers accounted for more than 10% of our total revenue in
the periods indicated above. We do not believe the loss of any existing
purchaser would have a material adverse effect on us.


MARKETING


    We market our natural gas and oil through monthly spot sales. Because sales
made under spot sales contracts result in fluctuating revenues to us depending
upon the market price of oil and gas, we from time to time enter into various
forward contracts covering a portion of our production to minimize the
fluctuations and the effect of price declines.


COMPETITION

    The oil and gas industry is highly competitive in all of its phases. We
encounter strong competition from other oil and gas companies in all areas of
our operations, including the acquisition of exploratory and producing
properties, the permitting and conducting of seismic surveys and the marketing
of oil and gas. Many of these competitors possess greater financial, technical
and other resources than us. Competition for the acquisition of producing
properties is affected by the amount of funds available to us, information about
producing properties available to us and any standards we establish from time to
time for the minimum projected return on investment. Competition also may be
presented by alternative fuel sources, including heating oil and other fossil
fuels. There has been increased competition for lower risk development
opportunities and for available sources of financing. In addition, the marketing
and sale of natural gas and processed gas are competitive. Because the primary
markets for natural gas liquids are

                                       32
<PAGE>
refineries, petrochemical plants and fuel distributors, prices generally are set
by or in competition with the prices for refined products in the petrochemical,
fuel and motor gasoline markets.

REGULATION


    GENERAL.  The oil and gas industry is extensively regulated by federal,
state and local authorities. In particular, oil and gas production operations
and economics is affected by environmental protection statutes, tax statutes and
other laws, rules and regulations relating to the petroleum industry, as well as
changes in these laws, changing rules and regulations and the interpretations
and applications of these laws, rules and regulations. Oil and gas industry
legislation and agency regulation are under constant review for amendment and
expansion for a variety of political, economic and other reasons. Numerous
regulatory authorities, and federal, state and local governments issue rules and
regulations binding on the oil and gas industry, some of which carry substantial
penalties for failure to comply. The regulatory burden on the oil and gas
industry increases our cost of doing business and, consequently, affects our
profitability. We believe we are in compliance with all federal, state and local
laws, regulations and orders applicable to us and our properties and operations,
the violation of which would have a material adverse effect on us or our
financial condition.



    SEISMIC PERMITS.  Current law in Louisiana requires permits from owners of
at least an undivided 80% interest in each tract over which we intend to conduct
seismic surveys. As a result, we may not be able to conduct seismic surveys
covering our entire area of interest in that state. Moreover, 3-D seismic
surveys typically are conducted from various locations both inside and outside
the area of interest to obtain the most detailed data of the geological features
within the area. To the extent that we are unable to obtain permits to access
locations to conduct the seismic surveys, the data obtained may not be as
detailed as might otherwise be available. In addition, a recent decision of a
federal court in Louisiana casts doubt on traditional seismic permitting
practices. That decision, in some instances, could lead to the surface owner
claiming ownership of the seismic data.



    EXPLORATION AND PRODUCTION.  Our operations are subject to various
regulations at the federal, state and local levels. The effect of these
regulations is to limit the amount of oil and gas we can produce from our wells
and to limit the number of wells or the locations at which we can drill. Such
regulations include:



    - requiring permits for the drilling of wells;



    - maintaining bonding requirements to drill or operate wells; and



    - regulating the location of wells, the method of drilling and casing wells,
      the surface use and restoration of properties upon which wells are
      drilled, the plugging and abandoning of wells and the disposal of fluids
      used in connection with well operations.



    Our operations also are subject to various conservation regulations. These
include:



    - the regulation of the size of drilling and spacing units;



    - the density of wells that may be drilled; and



    - the use or pooling of oil and gas properties.



    In addition, state conservation laws establish maximum rates of production
from oil and gas wells, generally prohibiting the venting or flaring of gas, and
impose certain requirements regarding the ratability of production.



    NATURAL GAS MARKETING, GATHERING AND TRANSPORTATION.  Federal legislation
and regulatory controls in the United States have historically affected the
price of the natural gas we produce and the manner in which our production is
marketed. The transportation and resale of natural gas in interstate commerce
are regulated by the Federal Energy Regulatory Commission pursuant to the
Natural Gas Act and the Natural


                                       33
<PAGE>

Gas Policy Act of 1978. Sales of our natural gas currently are made at market
prices and are not subject to federal or state price control.



    The FERC also regulates interstate natural gas transportation rates and
service conditions, which effect the marketing of natural gas we produce, as
well as the revenue we receive for sales of our natural gas. Since the latter
part of 1985, the FERC has endeavored to make interstate natural gas
transportation more accessible to gas buyers and sellers on an open and
nondiscriminatory basis. The FERC's efforts have significantly altered the
marketing and transportation of natural gas. Commencing in April 1992, the FERC
issued Order Nos. 636, 636-A, 636-B and 636-C (collectively, "Order No. 636"),
which, among other things, required interstate pipelines to "restructure" their
services to provide transportation separate or "unbundled" from the pipelines'
sales of gas. Also, Order No. 636 requires interstate pipelines to provide
open-access transportation on a nondiscriminatory basis that is equal for all
natural gas shippers.



    Order No. 636 has been implemented through decisions and negotiated
settlements in individual pipeline services restructuring proceedings. In many
instances, the result of Order No. 636 and related initiatives has been to
substantially reduce or eliminate the interstate pipelines' traditional role as
wholesalers of natural gas, and has substantially increased competition and
volatility in natural gas markets. The FERC has issued final orders in virtually
all Order No. 636 pipeline restructuring proceedings. In July 1996, the United
States Court of Appeals for the District of Columbia Circuit largely upheld
Order No. 636 and remanded certain issues for further explanation or
clarification. Numerous petitions for review of the individual pipeline
restructuring orders are currently pending in that court. The issues remanded
for further action do not appear to materially affect us. Proceedings on the
remanded issues are currently ongoing before the FERC following its issuance of
Order No. 636-C in February 1997. Although it is difficult to predict when all
appeals of pipeline restructuring orders will be completed or their impact on
us, we do not believe that it will be affected by the restructuring rule and
orders any differently than other natural gas producers and marketers with which
we compete.



    Although Order No. 636 does not regulate natural gas production operations,
the FERC has stated that Order No. 636 is intended to foster increased
competition within all phases of the natural gas industry. It is unclear what
impact, if any, increased competition within the natural gas industry under
Order No. 636 will have on us and our natural gas marketing efforts. Although
Order No. 636 could provide us with additional market access and more fairly
applied transportation service rates, terms and conditions, it could also
subject us to more restrictive pipeline imbalance tolerances and greater
penalties for violation of those tolerances. We do not believe, however, that we
will be affected by any action taken with respect to Order No. 636 materially
differently than other natural gas producers and marketers with which we
compete.



    The FERC has recently announced its intention to reexamine certain of its
transportation-related policies, including:



    - the appropriate manner for setting rates for new interstate pipeline
      construction;



    - the manner in which interstate pipeline shippers may release interstate
      pipeline capacity under Order No. 636 for resale in the secondary market;



    - the price that shippers can charge for their released capacity; and



    - the use of negotiated and market-based rates and terms and conditions for
      interstate gas transmission.


    Several pipelines have obtained FERC authorization to charge negotiated
rates as an alternative to traditional, cost-of-service rate making methodology.
In February 1997, the FERC announced a broad inquiry into issues facing the
natural gas industry to assist the FERC in establishing regulatory goals and
priorities in the post-Order No. 636 environment. In December 1997, the FERC
requested comments on the financial outlook of the natural gas pipeline
industry, including among other matters, whether the

                                       34
<PAGE>
FERC's current rate making policies are suitable in the current industry
environment. In April 1998, the FERC issued a new rule to further standardize
pipeline transaction tariffs that, as the result of newly standardized
provisions regarding firm intra day transportation nominations, could adversely
affect the reliability of scheduled interruptible transportation service on some
pipelines. While any resulting FERC action would affect us only indirectly, any
new rules and policy statements may have the effect of enhancing competition in
natural gas markets.


    Additional proposals and proceedings that might affect the natural gas
industry are considered from time to time by congress, the FERC and state
regulatory bodies. We cannot predict when or if any such proposals might become
effective, or their effect, if any, on our operations. The natural gas industry
historically has been very heavily regulated; therefore, there is no assurance
that the less stringent regulatory approach recently pursued by the FERC and
congress will continue indefinitely. The regulatory burden on the oil and
natural gas industry increases our cost of doing business and, consequently,
affects our profitability and cash flow. Since these laws and regulations are
frequently expanded, amended or reinterpreted, we are unable to predict the
future cost or impact of complying with these regulations.



    LOUISIANA LEGISLATION.  The Louisiana legislature passed Act 404 in 1993,
which permits a party transferring an oil field site to establish a
site-specific trust account for the transferred oil field. If the site-specific
trust account is established in accordance with the requirements of the statute,
the party transferring the oil field site may not thereafter be held liable by
the state for any site restoration costs or actions associated with the
transferred oil field site. The parties to a transfer may elect not to establish
a site-specific trust account. However, in the absence of a site-specific trust
account, the transferring party will continue to have liability for the costs of
restoration of the site. If the parties to a transfer elect to establish a
site-specific trust account under the statute, the Louisiana Department of
Natural Resources requires an oil field site restoration assessment to be made
at the time of the transfer or within one year thereafter to determine the site
restoration requirements existing at the time of transfer. Based upon the site
restoration assessment, the parties to the transfer must propose to the DNR a
funding schedule for the site-specific trust account, providing for some
contribution to the account at the time of transfer and at least quarterly
payment after that time. If the DNR approves the establishment and funding of
the site-specific trust account, the purchaser will be the responsible party to
the state, except that the failure of a transferring party to make a good faith
disclosure of all oil field site conditions existing at the time of the transfer
will render that party liable for the costs of restoration of the undisclosed
conditions in excess of the balance of the site-specific trust fund.



    OIL SALES AND TRANSPORTATION RATES.  The FERC also regulates rates and
service conditions for interstate transportation of crude oil, liquids and
condensate, which can affect the amount we receive from the sale of these
products. Transportation rates are generally subject to an indexing system under
which rates may be increased as long as they do not exceed an index rate that is
tied to inflation. Over time, this indexing system could have the effect of
increasing the cost of transporting crude oil, liquids and condensate by
pipeline. Our sales of crude oil, condensate and gas liquids are not regulated
and are made at market prices. The prices we receive from the sale of these
products is affected by the cost of transporting the products to market.



    ENVIRONMENTAL MATTERS.  Our oil and natural gas exploration, development and
production operations are subject to stringent federal, state and local laws
governing the discharge of materials into the environment or otherwise relating
to environmental protection. Numerous governmental agencies, like the
Environmental Protection Agency, issue regulations to implement and enforce
these laws, which often require difficult and costly compliance measures that
carry substantial civil and criminal penalties for failure to comply. These laws
and regulations may:



    - require the acquisition of a permit before drilling commences;


                                       35
<PAGE>

    - restrict the types, quantities and concentrations of various substances
      that can be released into the environment in connection with drilling and
      production activities;



    - limit or prohibit drilling activities on certain lands lying within
      wilderness, wetlands, ecologically sensitive and other protected areas;



    - require some form of remedial action to prevent pollution from former
      operations, such as plugging abandoning wells; and



    - impose substantial liabilities for pollution resulting from our
      operations.



    In addition, these laws, rules and regulations may restrict the rate of oil
and natural gas production below the rate that would otherwise exist. Changes in
environmental laws and regulations occur frequently, and any changes that result
in more stringent and costly waste handling, disposal or cleanup requirements
could adversely affect our operations and financial position, as well as those
of the oil and gas industry in general. While management believes that we are in
substantial compliance with current applicable environmental laws and
regulations and we have not experienced any material adverse effect from
compliance with these environmental requirements, there is no assurance that
this will continue in the future.


    The primary environmental statutory and regulatory programs that affect our
operations include the following:


        SUPERFUND.  The Comprehensive Environmental Response, Compensation and
    Liability Act, also known as "Superfund," imposes liability without regard
    to fault or the legality of the original conduct, on certain classes of
    persons who are considered to be responsible for the release of a "hazardous
    substance" into the environment. These persons include:



       - the current owner and operator of a facility from which hazardous
         substances are released;



       - owners and operators of the facility at the time the disposal of
         hazardous substances took place,



       - generators of hazardous substances who arranged for the disposal or
         treatment at or transportation to such facility of hazardous
         substances; and



       - transporters of hazardous substances to disposal or treatment
         facilities selected by them.



        Under CERCLA, any of these persons may be subject to joint and several
    liability for the costs of cleaning up the hazardous substances that have
    been released into the environment, for damages to natural resources and for
    the costs of certain health studies, and it is not uncommon for neighboring
    landowners and other third parties to file claims for personal injury and
    property damage allegedly caused by the release of hazardous substances or
    other pollutants into the environment. Furthermore, although petroleum,
    including crude oil and natural gas, is exempt from CERCLA, at least two
    courts have ruled that certain wastes associated with the production of
    crude oil may be classified as "hazardous substances" under CERCLA, and
    these wastes may become subject to liability and regulation under CERCLA.
    Regulatory programs aimed at remediation of environmental releases could
    have a similar impact on us.



        CLEAN WATER ACT.  The Federal Water Pollution Control Act of 1972, also
    known as the Clean Water Act, imposes restrictions and strict controls
    regarding the discharge of pollutants, including produced waters and other
    oil and gas wastes, into waters of the United States. The discharge of
    pollutants into regulated waters is prohibited, except in accordance with
    the terms of a permit issued by the EPA or the state. These proscriptions
    also prohibit certain activities in wetlands unless authorized by a permit
    issued by the U.S. Army Corps of Engineers. Sanctions for unauthorized
    discharges include administrative, civil and criminal penalties, as well as
    injunctive relief.


                                       36
<PAGE>

        OIL POLLUTION ACT.  The Oil Pollution Act of 1990 amends certain
    provisions of the CWA, and other statutes relating to the prevention of and
    response to spills or discharges of hazardous substances or oil into
    navigable waters. Under the OPA, a person owning or operating a facility or
    equipment (including land drilling equipment) from which there is a
    discharge or threat of a discharge of oil into or upon navigable waters or
    adjoining shorelines is liable, regardless of fault, as a "responsible
    party" for removal costs and damages. Federal laws impose strict, joint and
    several liability on facility owners for containment and clean up costs and
    certain other damages, including natural resource damages, arising from a
    spill.



        RCRA.  The Resource Conservation and Recovery Act, generally does not
    regulate most wastes generated by the exploration and production of oil and
    gas. RCRA specifically excludes from the definition of hazardous waste
    "drilling fluids, produced waters, and other wastes associated with the
    exploration, development, or production of crude oil, natural gas or
    geothermal energy." However, these wastes may be regulated by the EPA or
    state agencies as solid waste. Pipelines used to transfer oil and gas may
    also generate some hazardous wastes. Although the costs of managing solid
    and hazardous waste may be significant, we do not expect to experience more
    burdensome costs than similarly situated companies involved in oil and gas
    exploration and production.



        OTHER.  The EPA is also authorized to seek preliminary and permanent
    injunctive relief and, in certain cases, criminal penalties and fines. State
    laws governing the control of water pollution also provide varying civil and
    criminal penalties and liabilities in the case of releases of petroleum or
    its derivatives into surface waters or into the ground. If a discharge
    occurs at a well site at which we are conducting production operations, we
    may be exposed to claims that it is liable under the OPA, the CWA or similar
    state laws.


TITLE TO PROPERTIES

    Title to properties is subject to royalty, overriding royalty, carried
working, net profits, working and other similar interests and contractual
arrangements customary in the oil and gas industry, liens for current taxes not
yet due and other encumbrances. As is customary in the industry in the case of
undeveloped properties, little investigation of record title is made at the time
of acquisition (other than a preliminary review of local records).
Investigations, including a title opinion covering the drill site by local
counsel, generally are made before commencement of drilling operations. With
respect to acquisitions of producing properties, it is customary to review title
opinions, review engineering reserve reports and conduct environmental and
operational reviews before the closing of the purchase.

OPERATING HAZARDS AND INSURANCE


    The oil and gas business involves a variety of operating risks, including:



    - the risk of fire, explosions and blowouts;



    - pipe failure;



    - abnormally pressured formations; and



    - environmental hazards such as oil spills, gas leaks, ruptures or
      discharges of toxic gases.



    The occurrence of any of any of these events could result in substantial
losses to us due to injury or loss of life, severe damage to or destruction of
property, natural resources and equipment, pollution or other environmental
damage, cleanup responsibilities, regulatory investigation and penalties and
suspension of operations.


    We maintain an oil and gas lease operator insurance policy that insures us
against certain sudden and accidental risks associated with drilling, completing
and operating our wells. In addition, we require certain parties conducting
operations for us to maintain general comprehensive liability policies with
contractual

                                       37
<PAGE>

coverage to support the contractors' obligations to indemnify and defend us in
certain circumstances. There can be no assurance that this insurance will be
adequate to cover any losses or exposure to liability. We also carry
comprehensive general liability policies and an umbrella policy. Although we
believe that the amount of coverage we maintain is customary in the industry, it
does not provide complete coverage against all operating risks. An uninsured or
partially insured claim, if successful and of sufficient magnitude, could have a
material adverse effect on us and our financial condition. If we experience
significant claims or losses, our insurance premiums could be increased, which
may adversely affect us and our financial condition, or limit the ability of us
to obtain coverage. Any difficulty in obtaining coverage may impair our ability
to engage in our business activities.


LEGAL PROCEEDINGS


    We are involved in routine litigation arising in the ordinary course of
business. Management believes that the results of these proceedings,
individually and in the aggregate, will not have a material adverse effect on
our financial position or results of operations.


FACILITIES

    We maintain approximately 25,100 square feet of office space in Houston,
Texas, which is leased at an annual rent of $396,187. The lease expires January
31, 2003. We believe we will be able to renew the lease on acceptable terms, and
we currently are offering up to half of the space for sublease.

EMPLOYEES


    We had 21 full-time employees in our Houston, Texas office as of August 31,
1999. Their functions include management, production, engineering,
geoscientists, land, gas marketing, accounting, financial planning and
administration. Certain operations of our field activities are accomplished
through independent contractors who are supervised by us. We believe our
relations with our employees and contractors are good. None of our employees are
represented by a union.

DIRECTOR COMPENSATION

    Certain non-employee directors are individually awarded stock options and
receive cash compensation at the Board's discretion.

EMPLOYMENT AND TERMINATION AGREEMENTS


    We entered into a three-year employment agreement with Mr. LaFlure on
September 30, 1997 pursuant to which Mr. LaFlure served as our president and
chief operating officer. Under the employment agreement, Mr. LaFlure received a
monthly salary of $16,666.67 and an initial bonus of $100,000. Mr. LaFlure was
entitled to participate in all other employee compensation and welfare benefit
plans and programs available to our other employees and executive officers,
including, but not limited to, health, dental and 401(k) plans. If we terminated
the employment agreement other than for cause or for disability or death at any
time before the expiration date, we were obligated to pay Mr. LaFlure $1,500,000
minus the amount of monthly salary for each month Mr. LaFlure was paid; all cash
bonuses received by Mr. LaFlure before the termination; and the value of his
stock options.


    We terminated Mr. LaFlure's employment without cause effective January 15,
1999 and requested Mr. LaFlure to resign all of his positions with us except his
position as our director. Mr. LaFlure resigned as a director in April of 1999.
Pursuant to a settlement agreement, Mr. LaFlure was entitled to receive
$1,150,000 payable as follows:

    - Payments of $10,000 per month for 12 months commencing February 15, 1999;


    - Payment of $400,000 on January 15, 2000;


    - Payment of $200,000 on July 15, 2000; and


    - Payment of the balance due under his agreement, as adjusted (as described
      in the immediately following paragraphs), on January 15, 2001.



    In addition, Mr. LaFlure was granted new stock options in lieu of the
previous options for 300,000 shares of common stock granted on December 18,
1997. The new stock option agreement, dated February 15, 1999, is for 500,000
shares of common stock at an exercise price of Cdn.$0.53 per share. The
remaining amounts due under the settlement agreement payable on January 15,
2001, will be reduced by the difference between the option price under the new
option agreement for 500,000 shares of common stock and the 500,000 option
shares as of the date the payment of the balance of the agreed amounts. All cash
payments payable to Mr. LaFlure will be reduced by applicable federal, state of
local withholding taxes. We also agreed that at our sole cost and expense to
continue current health insurance coverage for Mr. LaFlure as required by
applicable law until January 15, 2000.



    We entered into a two-year employment agreement with Mr. Herlin on November
15, 1997. Under the agreement, Mr. Herlin received an initial monthly salary of
$11,250 and an initial bonus of $110,000. Mr. Herlin is entitled to participate
in all other employee compensation and welfare benefit plans and programs
available to our other employees and executive officers, including, but not
limited to, health, dental and 401(k) plans. If we terminate the employment
agreement other than for cause, disability or


                                       41
<PAGE>

death at any time before the expiration date, then we must pay to Mr. Herlin the
remaining amount of salary accrued or otherwise to be paid throughout the
remainder of the term of the agreement; provided that the remaining amount may
be no less than 12 months of Mr. Herlin's salary. If such termination is due to
a change of control of us, the minimum remaining amount must be equal to 24
months of Mr. Herlin's salary. If we terminate Mr. Herlin for cause, his
employment agreement terminates immediately and our sole remaining obligation is
to pay any amounts accrued through the date of termination.



    On December 16, 1998, we entered into an agreement with EnCap providing that
should Mr. Tomlinson's employment be terminated except for cause following
certain events, then EnCap will make a cash payment to Mr. Tomlinson of $1.0
million within 30 days of severance, enter into a consulting agreement with a
three-year term providing for payments of $185,000 per annum, and grant Mr.
Tomlinson a permanent overriding royalty interest in certain properties. These
payments are our obligations, but EnCap has agreed to provide financing to fund
our payment obligation.


OPTION REPRICING


    On February 19, 1999, the board re-priced stock options previously awarded
to certain of our employees, including our executive officers, one of our
directors and one contract employee. Options were re-priced at CDN. $0.50, which
was the previous 10-day average closing price of our common stock as reported on
Canada Stockwatch. The re-pricing of options held by the executive officers and
the director is subject to shareholder and regulatory approval.

                              CERTAIN TRANSACTIONS


RELATED PARTY TRANSACTIONS


    We have entered into several agreements with entities that are owned or
managed by certain of our directors, officers or other affiliates, or in which
certain of our directors, officers or affiliates have an interest. We also have
entered into agreements with certain of our former directors and officers.
Although some of these transactions were approved by our outside directors,
there can be no assurance that these transactions were negotiated at arms-length
or on terms that would have been negotiated with unaffiliated third parties. The
related entities with which we have entered into transactions include:


    - EnCap Capital Fund III L.P., a partnership whose general partner is EnCap
      Investments, L.C., which is managed by Robert L. Zorich and Gary Petersen,
      two of our directors;


    - Slattery Trust, a private trust of which Mr. Tomlinson is the beneficiary;

    - Starbucks Trust, a private trust of which Heather Tomlinson is the
      beneficiary;


    - Calibre Energy, LLC, a limited liability company owned by Slattery Trust,
      Starbucks Trust, Mr. Grabois and Robert Novak, and which is managed by
      Heather Tomlinson;


    - Lasco, an affiliate of EnCap;


    - Texstar Holdings, L.L.C., a private limited liability company owned by
      certain of our stockholders;


    - Stanford Energy, Inc., a company affiliated with Donald W. Busby, the
      former chairman of our board of directors; and


    - RP&C International, of which David Quint is a director and shareholder.



    ENCAP CREDIT FACILITY.  In 1997, we entered into a $20.0 million credit
agreement with EnCap consisting of an original note for $12.0 million and a
supplemental note for $8.0 million. The original note bore interest at 10.0% per
annum, and was due, with accrued interest, in December 1998. The supplemental
note bore interest at 10.0% per annum until July 1, 1998 and at 18.0% per annum
thereafter. Under the terms of the supplemental note, EnCap was issued warrants
for the purchase of 1.5 million shares of our common stock at an exercise price
of $1.28 per share. The original note was secured by a first lien on the
properties acquired and a second lien on certain other properties. The original
note was guaranteed by Mr. Tomlinson, Calibre and certain of Calibre's
affiliates.



    Under the original note, we agreed to convey to EnCap a 25.0% net profits
interest from the properties acquired with the proceeds of the borrowing. EnCap
also required Slattery Trust, Texstar Holdings and certain of our stockholders
to enter into a put/call agreement under which those stockholders, under certain
conditions, had the right to obtain or "call" the EnCap NPI in exchange for 1.5
million shares of our common stock. The put/call agreement also gave EnCap the
right, under certain conditions, to sell, or put, portions of the EnCap NPI to
those stockholders for $1.5 million or 3.5 million shares of our common stock as
of December 31, 1998 or March 31, 1999, respectively.



    The EnCap credit facility has been repaid in full, and the stockholders'
rights and obligations under the put/call agreement have been transferred to us.



    OTHER ENCAP TRANSACTIONS.  In August 1999, we entered into a new $2.9
million credit facility with EnCap that bears interest at the rate of 10.0% per
annum and matures on December 31, 2000. In addition, we issued to $4.4 million
of redeemable class A, series I preferred stock to an entity affiliated with
EnCap. We paid the EnCap affiliate a placement fee of $100,000. The proceeds
from these transactions were used to make payments under the agreement with our
trade creditors and for general corporate purposes.


    STANFORD ENERGY DEBENTURE.  In August 1997, Stanford Energy issued us an
unsecured convertible debenture in the principal amount of Cdn.$200,000. The
debenture bore interest at a rate of 8.0% per annum, payable quarterly. The
debenture was repaid on August 6, 1997.

    ADVANCES TO CALIBRE EQUADOR.  In the Spring of 1997, we and Slattery Trust,
Starbucks Trust, Mr. Grabois, Mr. Novak and James Alexander formed Calibre
Ecuador, Inc. to develop certain oil and gas

                                       43
<PAGE>

prospects in Ecuador. We owned 50% of the outstanding common stock of Calibre
Ecuador and the other parties collectively owned the other 50%. The development
of the prospects required enactment of certain enabling legislation that would
permit non-Ecuador citizens to own oil and gas properties in Ecuador. Pending
the enactment of the legislation, we advanced funds to Calibre Ecuador to
generate the prospects. The advances were non-interest bearing and due upon
demand. All rights to the prospects were contributed to Calibre Ecuador by the
parties other than us. As of December 31, 1997, we had written off advances
totaling $402,192 made to Calibre Ecuador. Calibre Ecuador had no means with
which to repay the advances. Due to the write-off, we obtained rights to
substantially all of Calibre Equador's common stock.



    In November, 1998, we entered into a participation agreement with Burlington
Resources International Inc. to develop the prospects in Ecuador. We and
Burlington have participation interests of 25% and 75%, respectively. Burlington
has not renewed the agreement; however, we retained a 25% interest in any
project related to the subject area pursued by Burlington for one year.


    CALIBRE TRANSACTIONS.  In December 1997, we advanced funds to Calibre Oil &
Gas, Inc. Net advances to Calibre Oil & Gas, Inc. totaled $1,768,772 at December
31, 1997. The advances bore no interest and were due upon demand.


    On April 22, 1998, in a single transaction, we acquired all of the
outstanding shares of Calibre Oil & Gas, Inc. from Calibre and certain oil and
gas properties owned by the Slattery Trust, the Starbucks Trust, Mr. Grabois,
Mr. Novak, Mr. Tomlinson and Calibre Oil & Gas, Inc. The shares of Calibre Oil &
Gas, Inc. were valued at $3,820,713 and were paid for through the issuance to
Calibre of 1,927,426 shares of our common stock valued at Cdn. $2.80 per share.
The total purchase price for the oil and gas properties acquired from the other
parties was $2,261,000, paid $261,000 in cash and $2,000,000 in promissory notes
issued by Texstar Petroleum Inc. in differing amounts to each party. These notes
were guaranteed by us, bore 10% annual interest and were to be repaid in two
equal installments due on April 1, 1998 and September 1, 1998. The purchase
price was to be adjusted by a credit for proceeds from production attributable
to each property through January 31, 1998.


    In connection with the acquisition of the oil and gas properties and shares
of Calibre Oil & Gas, Inc., $1.45 million of the advances to Calibre Oil & Gas,
Inc. were reclassified as an assumption of payables and the remaining $318,772
was written off as a bad debt. Calibre Oil & Gas, Inc. was subsequently merged
into us and ceased to exist on January 7, 1999.


    LASCO ACQUISITION.  In January 1998, and effective on December 1, 1997, we
acquired proved reserves in Texas and Louisiana from Lasco for 2.57 million
shares of our common stock and 12.0 million shares of our series 1 preferred
stock. In December 1998, we reconveyed a portion of those interests to Lasco in
exchange for approximately 2.5 million shares of our series 1 preferred stock.



    STARBUCKS NOTE.  On January 1, 1998, we loaned Starbucks Trust $2.5 million
pursuant to a promissory note due December 31, 1998 that bears interest at 9.0%
per annum. Total advances and accrued interest under the note are $3.3 million
as of June 30, 1999. The loan was intended to:



    - give us a greater return on investment than we were receiving at the time;



    - acquire common stock that was reconveyed by Starbucks Trust to the holders
      of our series 2 debentures in an effort to deliver to those debenture
      holders freely tradeable common stock; and


    - acquire shares of our common stock in the open market to support the
      public trading price.

    The entire principal interest outstanding under the note remains due and
payable and is carried on our books as an account receivable; however, Starbucks
Trust lost money on the securities transactions it made with the proceeds of the
loan and currently is unable to repay the loan.


    Starbucks Trust has claimed and requested credits for expenses incurred on
behalf of us against the amounts owed under the note of Cdn. $740,240.
Separately, and pursuant to the terms of the Starbucks Trust acquisition
agreement, we owe the Starbucks Trust $1,283,462 inclusive of accrued interest
as of December 31, 1998. Pursuant to the Calibre acquisition agreement, as of
December 31, 1998, we further


                                       44
<PAGE>

owe the Starbucks Trust $213,918 and Mr. Tomlinson $1,588,489 inclusive of
accrued interest. On December 28, 1998, as part of the Shell transaction, these
parties, Texstar Holdings, LLC and Security Oil, LLC signed a standstill
agreement under which all parties mutually deferred payments and further agreed
not to pursue collection of any amounts until the termination date of the Shell
transaction and to toll the applicable statutes of limitations related to claims
arising from any of these amounts until the earlier of the termination date or
December 31, 2003.



    STARBUCKS ACQUISITION.  In July 1998, we entered into the Starbucks
acquisition, pursuant to which we acquired certain proved non-producing oil and
gas properties in Mississippi, Texas and Louisiana from Starbucks Trust for
$2.33 million and 600,000 shares of our common stock. The purchase value is
guaranteed and secured by 2.1 million shares of our common stock owned by the
Starbucks Trust.



    OTHER RELATED PARTY TRANSACTIONS.  We had an agreement with DWB Management
Ltd. to provide management, professional and office services. DWB Management is
a private company owned by Donald W. Busby, our former chairman of the board.
Under the agreement, we paid DWB for services rendered a fee of Cdn.$8,000 per
month. The agreement with DWB Management was terminated in September 1997.


    We entered into an agreement with Chase Management Ltd. to provide
management, professional and office services to us, including daily accounting
services as required, and general legal assistance for routine Canadian
securities filings. Chase Management is a private company owned by Nick DeMare,
one of our former officers and directors. The agreement was for one year
commencing on the first day of October 1997 through the last day of September
1998. Thereafter, the agreement continues in effect from year to year unless
terminated by either party upon 60 days' written notice. During our last fiscal
year, we paid Chase Management Cdn.$60,000 and for the remaining term of the
agreement, we will pay Chase Management Cdn.$5,000 per month for services
rendered.


SECURITIES SUBJECT TO POOLING AGREEMENTS



    After we were formed through the reverse merger of Texstar Oil & Gas, Inc.
into Benz Equities Ltd. (our Canadian predecessor), we conducted a public
offering of equity securities in Canada. The underwriters in that public
offering required our controlling stockholders to enter into a pooling agreement
under which those stockholders deposited their Benz shares into a pooled account
to prevent sales of those shares into the Canadian public markets for a
specified time period. After the registration statement relating to that public
offering was filed with the Ontario Securities Commission, the OSC required the
stockholders to enter into an escrow agreement with respect to sales of the
securities subject to the pooling agreement and certain additional shares of our
common stock. Set forth below is a summary of the pooling and escrow
arrangements.



    Under a pooling agreement dated April 18, 1997, as amended on September 11,
1997, between us, certain of our stockholders, including Mr. Tomlinson, and
other members of our senior management, and Montreal Trust, our registrar and
transfer agent, as well as the agent under the pooling agreement, a total of
10,342,497 shares of our common stock were deposited on a pooled basis. In
addition, a total of 2,000,000 shares of common stock to be issued on exercise
of outstanding share purchase warrants were, once exercised, to be deposited and
held by Montreal Trust pursuant to the terms and conditions of the pooling
agreement. All common stock subject to the pooling agreement will be released
over a period of three years ending August 31, 2000, subject to earlier release
from the pool in certain circumstances. As of August 30, 1999, a total of
313,000 shares of our common stock are held by Montreal Trust pursuant to the
terms and conditions of the pooling agreement.



    Under an escrow agreement dated September 15, 1997, between us, certain of
our stockholders, Mr. Tomlinson, Mr. Busby and Montreal Trust, a total of
13,505,780 shares of our common stock were deposited with Montreal Trust to be
held in escrow pursuant to the escrow agreement. All common stock subject to the
escrow agreement will be released in accordance with the policies of the Ontario
Securities


                                       45
<PAGE>

Commission. As of August 30, 1999, a total of 10,804,624 shares of our common
stock are held in escrow by Montreal Trust pursuant to the escrow agreement.



    Under an option agreement between Boone Petroleum Inc., a corporation
controlled by Mr. Busby, and Texstar Petroleum, L.L.C., a company controlled by
Mr. Tomlinson, Boone Petroleum Inc. granted Texstar Petroleum, L.L.C. an option
to purchase 1,200,000 shares of our common stock from Boone Petroleum Inc. The
option was exercised and 1,100,000 shares of our common stock were transferred
within escrow on September, 1998 to Texstar Petroleum, L.L.C. As of the date of
this prospectus, the remaining 100,000 shares of common stock have not been
transferred within escrow.



    Under an unsigned agreement dated October 9, 1997, between us, EnCap Energy,
Montreal Trust, Texstar Holdings, L.L.C., the Slattery Trust, Texstar Holdings,
L.L.C. and the Slattery Trust granted to EnCap Energy a security interest in
535,521 shares of our common stock owned by Texstar Holdings, L.L.C. and
5,525,000 shares of our common stock owned by the Slattery Trust subject to the
escrow agreement.

                            SELLING SECURITYHOLDERS



    The following table sets forth certain information with respect to our class
A, series II convertible preferred stock and common stock being offered for
resale by the selling securityholders listed below. Unless otherwise noted, the
persons named below have sole voting and investment power with respect to their
securities. None of the selling securityholders listed below currently own any
shares of our common stock. The common stock beneficially owned by them is
solely by virtue of owning class A, series II convertible preferred stock or
currently exercisable warrants.



    The beneficial ownership of the convertible preferred stock and the common
stock issuable upon conversion of the convertible preferred stock and exercise
of the warrants by the selling securityholders after this offering will depend
on the number of shares of convertible preferred stock or common stock sold by
each selling securityholder; however, the table assumes that all shares of
convertible preferred stock and common stock issued upon conversion of the
convertible preferred stock and exercise of the warrants by a selling
securityholder are offered and resold pursuant to this prospectus. Therefore, no
information is given with respect to the beneficial ownership of convertible
preferred stock or common stock following this offering.

                              PLAN OF DISTRIBUTION

    This prospectus relates to the resale of:


    - 239,701 shares of our convertible preferred stock;



    - 101,407,269 shares of our common stock issuable upon conversion of the
      convertible preferred stock;



    - 3,974,923 shares of common stock issuable upon the exercise of outstanding
      warrants to purchase our common stock; and



    - 4,583,726 shares of our issued and outstanding common stock previously
      issued to the selling securityholders;



    This prospectus relates to the resale of common stock issued in connection
with the exercise of outstanding warrants, but does not relate to the invoice of
the common stock issued upon exercise of the warrants.


    We will bear all costs, expenses and fees in connection with registration of
the securities covered by this prospectus. Brokerage commissions and similar
selling expenses, if any, attributable to the resale of the convertible
preferred stock or common stock issued upon the conversion of convertible
preferred stock or exercise of warrants will be borne by the selling
securityholders.


    Sales of the securities covered by this prospectus may be effected by
selling securityholders from time to time in one or more types of transactions
(which may include block transactions) in the over-the-counter market, in
negotiated transactions, through put or call options transactions relating to
the securityholders, or a combination of these methods of sale, at market prices
prevailing at the time of sale, or at negotiated prices. These transactions may
or may not involve brokers or dealers. The selling securityholders have advised
us that they have not entered into any agreements, understandings or
arrangements with any underwriters or broker-dealers regarding the sale of their
warrants or common stock issued upon exercise of the warrants, nor is there an
underwriter or coordinating broker acting in connection with the proposed sale
of warrants or common stock issued upon exercise of the warrants by the selling
securityholders.



    The selling securityholders may effect these transactions by selling
convertible preferred stock or common stock issued upon conversion of
convertible preferred stock or exercise of the warrants directly to purchasers
or to or through broker-dealers, which may act as agents or principals. These
broker-dealers may receive compensation in the form of discounts, concessions,
or commissions from the selling securityholders or the purchasers of warrants
for whom the broker-dealers may act as agents or to whom they sell as principal,
or both, which compensation as to a particular broker-dealer might be in excess
of customary commissions.



    The selling securityholders and any broker-dealers that act in connection
with the sale of convertible preferred stock might be deemed to be
"underwriters" within the meaning of Section 2(11) of the Securities Act, and
any commissions received by the broker-dealers and any profit on the resale of
the warrants or common stock issued upon exercise of the warrants sold by them
while acting as principals might be deemed to be underwriting discounts or
commissions under the Securities Act. The selling securityholders may agree to
indemnify any agent dealer or broker-dealer that participates in transactions
involving sales of the convertible preferred stock or common stock issued upon
conversion of convertible preferred stock or exercise of the warrants against
certain liabilities, including liabilities arising under the Securities Act.


    Because selling securityholders may be deemed to be "underwriters" within
the meaning of Section 2(11) of the Securities Act, the selling securityholders
may be subject to the prospectus delivery requirements of the Securities Act.

                                       51
<PAGE>

    Selling securityholders also may resell all or a portion of the convertible
preferred stock or common stock issued upon conversion of convertible preferred
stock or exercise of the warrants in open market transactions in reliance upon
Rule 144 under the Securities Act, provided they meet the criteria and conform
to the requirements of that rule.



    After we are notified by a selling securityholder that any material
arrangement has been entered into with a broker-dealer for the sale of
convertible preferred stock or common stock issued upon conversion of
convertible preferred stock or the exercise of warrants, a supplement to this
prospectus will be filed, if required, under Rule 424(b) under the Securities
Act, disclosing:



    - the name of each selling securityholder and of the participating
      broker-dealer(s);



    - the type and number of securities involved;



    - the price at which the securities were sold;



    - the commissions paid or discounts or concessions allowed to such
      broker-dealer, where applicable;



    - that the broker-dealer did not conduct any investigations to verify the
      information set out by in this prospectus and;



    - other facts material to the transaction.

                          DESCRIPTION OF CAPITAL STOCK


    Our certificate of incorporation provides for authorized capital stock of
400,000,000 shares, consisting of 300,000,000 shares of common stock, par value
$0.01 per share and 100,000,000 shares of preferred stock, par value $1.00 per
share. As of August 31, 1999, 39,870,617 shares of common stock, 13,488,140
class A, series I preferred stock and 239,701 shares of class A, series II
convertible preferred stock were issued and outstanding.


COMMON STOCK


    Holders of common stock are entitled to one vote per share in the election
of directors and on all other matters on which stockholders are entitled or
permitted to vote. Holders of common stock are not entitled to cumulative voting
rights. Therefore, holders of a majority of the shares voting for the election
of directors can elect all the directors. Subject to the terms of any
outstanding series of preferred stock, the holders of common stock are entitled
to dividends in the amounts and at the times as our board of directors may
declare out of funds legally available for the payment of dividends. Upon
liquidation or dissolution, holders of common stock are entitled to share
ratably in all net assets available for distribution to stockholders after
payment of any liquidation preferences to holders of preferred stock. Holders of
common stock have no redemption, conversion or preemptive rights.


    Our common stock is traded on the Vancouver Stock Exchange under the symbol
"BZG." We plan to post our common stock for trading on the Nasdaq Bulletin
Board. The transfer agent for our common stock is Montreal Trust.

PREFERRED STOCK


    The board of directors has the authority to cause us to issue up to the
authorized number of shares of preferred stock in one or more series, to
designate the number of shares constituting any series, and to fix the
applicable rights, preferences, privileges and restrictions, including dividend
rights, voting rights, redemption and conversion rights and liquidation
preferences of any series, without further action by the stockholders. The
issuance of preferred stock with voting and conversion rights may adversely
affect the voting power of the holders of the common stock.


    SERIES II PREFERRED STOCK.  Set forth below is a summary of the terms of our
outstanding Series II preferred stock.


        DIVIDENDS.  The shares of series II preferred stock are entitled to
    dividends payable semiannually in arrears on March 31 and September 30 of
    each year. The dividend rate from the date of issuance through March 31,
    2003 is 8.0% per annum. After March 31, 2003, dividends will accrue at the
    rate of 15.0% per annum. If dividends are not timely paid, annual dividends
    will be increased by 3.0% until the past-due dividends have been paid.
    Dividends are payable, at our option, in freely tradeable common stock
    valued at the average of the market price of the common stock for the 20
    consecutive trading days ending five trading days before the dividend
    payment date. Market price is defined as the weighted average price of our
    common stock on the principal stock exchange on which our common stock is
    traded.



        LIQUIDATION PREFERENCE.  Upon any liquidation, dissolution or winding
    up, voluntary or involuntary, the shares of Series II preferred stock are
    entitled to a liquidation preference to the common stock of a cash amount
    equal to $105 per share.



        OPTIONAL CONVERSION.  Through March 31, 2000, the series II preferred
    stock will be convertible at the option of the holder into common stock at
    an initial conversion rate equal to CDN $0.35. If on March 31, 2000, the
    average of the market price during the preceding 20 consecutive trading days
    is lower than the preferred conversion price, then the conversion price will
    be adjusted downward to that


                                       53
<PAGE>

    average price. If the series II preferred stock is not freely tradeable on
    October 1, 1999, the preferred conversion price will be reduced thereafter
    by 5.0% for each six-month period or portion thereof until the series II
    preferred stock is freely tradeable.



        MANDATORY REDEMPTION.  We may cause all of the series II preferred stock
    to be converted into common stock at the then preferred conversion price at
    any time after March 31, 2000 if the market price for the 20 consecutive
    trading days ending not more than five days before the giving of the notice
    is equal to or in excess of 140% of the preferred conversion price then in
    effect, and the common stock to be received in connection with the
    conversion is freely tradeable. Upon any mandatory conversion of any series
    II preferred stock, we will make payment of dividends accrued during the
    period from the most recent dividend payment date to the conversion date.



        REDEMPTION.  The Series II preferred stock is redeemable in whole or in
    part by us at any time on the giving of 30 days' written notice at 105% of
    the nominal amount thereof together with any accrued but unpaid dividends,
    payable in cash. Beginning April 1, 2003, at our option, the Series II
    preferred stock also may be redeemed for freely tradeable common stock:



       - at 115% of the redemption value if our market capitalization is $300
         million or more on such date;



       - or at 120% of the redemption value if our market capitalization is less
         than $300 million on such date.


        The common stock issued will be valued at the average market price for
    the 20 trading days ending five trading days before the payment date.


        RANKING.  The series II preferred stock will rank PARI PASSU with the
    series I preferred stock and any new issue of preferred stock that
    stipulates a liquidation preference PARI PASSU with the series II preferred
    stock and senior to our other equity. The series II preferred stock will be
    subordinate to claims of creditors, including holders of our outstanding
    debt instruments.



        CERTAIN COVENANTS.  During the period that any of the series II
    preferred stock is outstanding, we must maintain tangible assets equal to or
    greater than 100% (rising to 140% with respect to the years ending December
    31, 2000 and after) of long-term debt (which includes the series II
    preferred stock, the series I preferred stock, and any preferred stock
    ranking PARI PASSU with either such series of preferred stock).



        VOTING RIGHTS.  The series II preferred stock has no voting rights
    before conversion except as provided by law.



        LISTING.  The convertible preferred stock currently is not listed for
    trading on any stock exchange. We plan to post the series II preferred stock
    for trading on the Nasdaq Bulletin Board. The transfer agent for the
    convertible preferred stock is American Stock Transfer Company.


PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND DELAWARE LAW


    Our certificate of incorporation authorizes the board of directors, without
stockholder approval, to establish and to issue shares of one or more series of
preferred stock, with each series having the voting rights, dividend rates,
liquidation, redemption, conversion and other rights as may be fixed by the
board. Our bylaws direct that special meetings of the stockholders may only be
called by a majority of the members of the board of directors, the chairman of
the board of directors, the president or the holders of not less than 30% of the
total voting power of all shares of our capital stock entitled to vote in the
election of directors. The bylaws further provide that stockholders' nominations
to the board of directors and other stockholder business proposed to be
transaction at stockholder meetings must be timely received by us in a proper
written form which meets the prescribed content requirements.


                                       54
<PAGE>
    The above provisions may have the effect of deterring certain tender offers
or hostile takeovers or may delay or prevent changes in control of our
management.

LIMITATION OF DIRECTOR LIABILITY


    Section 102(b)(7) of the Delaware General Corporation Law authorizes
corporations to limit or eliminate the personal liability of directors to
corporations and their stockholders for monetary damages for breach of
directors' fiduciary duty of care. Although section 102(b) does not change
directors' duty of care, it enables corporations to limit available relief to
equitable remedies such as injunction or rescission. Our certificate of
incorporation limits the liability of our directors or our stockholders (in
their capacity as directors but not in their capacity as officers) to the
fullest extent permitted by section 102(b). Specifically, our directors will not
be personally liable for monetary damages for breach of a director's fiduciary
duty as a director, except for liability:



    - for any breach of the director's duty of loyalty to us or our
      stockholders;



    - for acts or omissions not in good faith or that involve intentional,
      misconduct or a knowing violation of law;



    - for unlawful payments of dividends or unlawful stock repurchases or
      redemptions as provided in section 174 of the Delaware General Corporation
      Law; or



    - for any transaction from which the director derived an improper personal
      benefit.


INDEMNIFICATION


    To the maximum extent permitted by law, our certificate of incorporation and
bylaws provide for mandatory indemnification of directors, and permit
indemnification of our officers, employees and agents against all expense,
liability and loss to which they may become subject or which they may incur as a
result of being or having been a director, officer, employee or agent. In
addition, we must advance or reimburse directors, and may advance or reimburse
officers, employees and agents, for expenses incurred by them in connection with
indemnifiable claims.


DELAWARE ANTI-TAKEOVER LAW


    Section 203 of the Delaware General Corporation Law generally provides that
an "interested stockholder," which is a stockholder acquiring more than 15% of
the outstanding voting stock of a corporation subject to the statute but less
than 85% of that stock, may not engage in certain " business combinations" with
the corporation for a period of three years after the date on which the
stockholder became an interested stockholder unless:



    - before such date, the corporation's board of directors approved either the
      business combination or the transaction in which the stockholder became an
      Interested Stockholder; or



    - the business combination is approved by the corporation's board of
      directors and authorized at a stockholders' meeting by a vote of at least
      two-thirds of the corporation's outstanding voting stock not owned by the
      interested stockholder.



    Under section 203, these restrictions will not apply to certain business
combinations proposed by an Interested Stockholder following the earlier of the
announcement or notification of one of certain extraordinary transactions
involving the corporation and a person who were not an interested stockholder
during the previous three years or who became an interested stockholder with the
approval of the corporation's board of directors, if the extraordinary
transaction is approved or not opposed by a majority of the directors who were
directors before any person becoming an interested stockholder during the
previous three years or were recommended for election or elected to succeed such
directors by a majority of such directors.


                                       55
<PAGE>

    Section 203 defines the term "business combination" to encompass a wide
variety of transactions with or caused by an Interested Stockholder, including
transactions in which the interested stockholder receives or could receive a
benefit on other than a pro rata basis with other stockholders, such as mergers,
certain asset sales, certain issuances of additional shares to the interested
stockholder, transactions with the corporation that increase the proportionate
interest in the corporation directly or indirectly owned by the interested
stockholder, or transactions in which the interested stockholder receives
certain other benefits.



    The provisions of section 203, together with the ability of our board of
directors to issue preferred stock without further stockholder action, could
delay or frustrate the removal of incumbent directors or a change in our
control. The provisions also could discourage, impede or prevent a merger,
tender offer or proxy contest, even if those events would be favorable to the
interests of stockholders. Our stockholders, by adopting an amendment to our
certificate of incorporation or bylaws, may elect not to be governed by section
203 effective 12 months after such adoption of the amendment. Neither our
certificate of incorporation nor bylaws currently exclude us from the
restrictions imposed by section 203.

    Certain legal matters in connection with the class A, series II convertible
preferred stock and common stock offered hereby are being passed upon for us by

                          INDEPENDENT AUDITOR'S REPORT

To the Board of Directors and Stockholders
  BENZ ENERGY LTD.

We have audited the accompanying consolidated balance sheets of BENZ ENERGY LTD.
as of December 31, 1998 and 1997 and the related consolidated statements of
operations, comprehensive income, stockholders' equity, and cash flows for the
year ended December 31, 1998 and for the periods from September 1, 1997 to
December 31, 1997 and from October 31, 1996 (inception) to August 31, 1997.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of BENZ
ENERGY LTD. as of December 31, 1998 and 1997 and the consolidated results of its
operations and its consolidated cash flows for the year ended December 31, 1998,
the four month period ended December 31, 1997 and the ten month period ended
August 31, 1997 in conformity with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 18 to the
financial statements, the Company has experienced significant delays in the
completion of certain wells and its limited capital resources raise substantial
doubt about its ability to continue as a going concern. Management's plans in
regard to these matters are also described in Note 18. The financial statements
do not include any adjustments that might result from the outcome of this
uncertainty.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    NATURE OF OPERATIONS--Benz Energy Ltd. ("Benz" or the "Company") is an
independent energy company engaged primarily in the acquisition, development,
production, exploration for and the sale of oil, gas and natural gas liquids.
The Company's exploration and production activities are located primarily in the
Gulf Coast areas of Mississippi, Louisiana and Texas. Benz treats all operations
as one segment of business. The principal executive offices of the Company are
located at 1000 Louisiana, 15th Floor, Houston, Texas 77002. The Company's
registered and records office is located at 3081 Third Avenue, Whitehorse, Yukon
Y1A 4Z7 Canada.

    The Company's future financial condition and results of operations will
depend upon prices received for its oil and natural gas and the costs of
finding, acquiring, developing and producing reserves. Prices for oil and
natural gas are subject to fluctuations in response to changes in supply, market
uncertainty and a variety of other factors beyond the Company's control. These
factors include worldwide political instability (especially in the Middle East),
the foreign supply of oil and natural gas, the price of foreign imports, the
level of consumer product demand and the price and availability of alternative
fuels. With natural gas accounting for 89 percent of Benz's 1998 production on
an energy equivalent basis, the Company was affected more by fluctuations in
natural gas prices than in oil prices.


    CHANGE IN ACCOUNTING PRINCIPLE--The Company changed its method of accounting
from the successful efforts method to the full cost method of accounting for oil
and gas properties during the period ended December 31, 1997. The Company
decided to make this change due to the fact that the majority of its peer group
uses full cost accounting and the change makes the Company more comparable to
its peer group for financial reporting purposes. The prior period presented has
been restated to reflect the change in accounting. If the Company had not
restated the financial statements for the period ended August 31, 1997, the loss
for that period would have been $4,995,260 and the loss per share would have
been $(0.23).



    CHANGE IN FISCAL YEAR--The Company changed its fiscal year end to December
31 from August 31, effective with the four month period ended December 31, 1997.


    BASIS OF CONSOLIDATION--The consolidated financial statements include the
accounts of Benz Energy Ltd. and its wholly owned subsidiaries Texstar
Petroleum, Inc. ("Texstar") and Benz Properties Ltd. ("Benz Properties").
Accordingly, all references herein to Benz or the Company include the
consolidated results of its subsidiaries. All significant intercompany accounts
and transactions have been eliminated in consolidation.

    BASIS OF PRESENTATION--Effective October 31, 1996, Benz acquired 100% of the
outstanding capital stock of Texstar (See Note 2). As a result, Texstar's former
shareholders obtained control of Benz. For accounting purposes, this acquisition
has been treated as a recapitalization of Texstar.

    The financial statements presented include only the accounts of the Company
since Texstar's inception (October 31, 1996).

    USE OF ESTIMATES--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. Significant
estimates with regard to these financial statements include the estimate of
proved oil and gas reserve volumes and the related present value of estimated
future net revenues therefrom (see Note 24, "Supplemental Oil and Gas
Disclosures").

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    CASH AND CASH EQUIVALENTS--Cash and Cash Equivalents include cash in banks
and other cash equivalents that mature within three months of the date of
purchase.

    OIL AND GAS PROPERTIES--The Company uses the full cost method of accounting
for its investment in oil and gas properties. Under this method, the Company
capitalizes all acquisition, exploration and development costs incurred for the
purpose of finding oil and gas reserves, including salaries, benefits and other
internal costs directly attributable to these activities. Capitalized internal
costs were as follows for the periods indicated:

<TABLE>
<S>                                                                 <C>
Year ended December 31, 1998......................................  $ 829,835
Four months ended December 31, 1997...............................  $ 335,626
Ten months ended August 31, 1997..................................  $ 412,752
</TABLE>

Interest costs related to unproved properties and properties under development
are also capitalized to oil and gas properties. Unless a significant portion of
the Company's reserve volumes are sold (generally greater than 25 percent),
proceeds from the sale of oil and gas properties are accounted for as reductions
to capitalized costs and gains or losses are not recognized.

    Benz computes the provision for depreciation, depletion and amortization
(DD&A) of oil and gas properties on a quarterly basis using the
units-of-production method based upon production and estimates of proved reserve
quantities. Unevaluated costs and related capitalized internal and interest
costs are excluded from the amortization base until the properties associated
with these costs are evaluated. The amortizable base includes estimated
dismantlement, reclamation and abandonment costs net of equipment salvage
values. The engineering department of Benz generally estimates these future
costs.

    Benz limits, by country, net capitalized costs of proved oil and gas
properties, less related deferred income taxes, to the sum of (1) future net
revenues (using prices and cost rates as of the balance sheet date) from proved
reserves and discounted at ten percent per annum, plus (2) costs not being
amortized, less (3) related income tax effects. Excess costs, if any, are
charged to proved property impairment expense.

    The costs of certain unevaluated leasehold acreage and wells being drilled
are not being amortized. Costs not being amortized are periodically assessed for
impairments. Any impairment is added to the amortization base.

    DEPRECIATION AND AMORTIZATION--Property and equipment are stated at cost and
are depreciated using the straight-line method over their estimated useful
lives. The costs of maintenance and repairs are charged to expense when
incurred; costs of renewals and betterments are capitalized. Upon the sales or
retirement of property and equipment, the cost and related accumulated
depreciation are eliminated from the respective accounts and the resulting gain
or loss is included in operations.

    REVENUE RECOGNITION--Revenues from the sale of oil and gas production are
recognized when title passes, net of royalties. Natural gas revenues are
generally recognized under the entitlements method of accounting for gas
imbalances, i.e., monthly sales quantities that do not match the Company's
entitled share of joint production. Entitled quantities in excess of sales
quantities are recorded as a receivable from joint venture partners. The
receivable is carried at the lower of current market price or the market price
at the time the imbalance occurred. Sales quantities in excess of entitled
quantities are recorded as deferred revenue carried at the gas market price
received at the time the imbalance occurred.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    HEDGING--The Company may enter into derivative contracts to hedge the risk
of future oil and gas price fluctuations. Such contracts may either fix or
support oil or gas prices or limit the impact of price fluctuations with respect
to the Company's sales of oil and gas. Gains and losses on such hedging
activities are recognized in oil and gas revenues when the hedged production is
sold. Hedged oil and gas prices, if any, used in computing the year-end
standardized measure of discounted future net cash flows relating to proved oil
and gas reserves reflect the estimated effects of hedging contracts existing at
year end.

    INVESTMENT IN EQUITY SECURITIES--The Company accounts for its investments in
equity securities under the provisions of Financial Accounting Standards Board
("FASB") Statement of Financial Accounting Standards ("SFAS") No. 115,
"Accounting for Certain Investments in Debt and Equity Securities". This
standard provides that available-for-sale investments in securities that have
readily determinable fair values be measured at fair value in the balance sheet
and that unrealized holding gains and losses for these investments be reported
in a separate component of stockholders' equity until realized.

    LONG-LIVED ASSETS--Long-lived assets to be held and used are reviewed for
impairment whenever events or changes in circumstances indicate that the related
carrying amount may not be recoverable. When required, impairment losses on
assets to be held and used are recognized based on the fair value of the assets
and long-lived assets to be disposed of are reported at the lower of carrying
amount or fair value less cost to sell.

    INCOME TAXES--Provisions for income taxes are based on taxes payable or
refundable for the current year and deferred taxes on temporary differences
between the amount of taxable income and pretax financial income and between the
tax bases of assets and liabilities and their reported amounts in the financial
statements. Deferred tax assets and liabilities are included in the financial
statements at currently enacted income tax rates applicable to the period in
which the deferred tax assets and liabilities are expected to be realized or
settled as prescribed SFAS No. 109, "Accounting for Income Taxes". As changes in
tax laws or rates are enacted, deferred tax assets and liabilities are adjusted
through the provision for income taxes.

    CONCENTRATION OF CREDIT RISK--The Company places its cash in what it
believes to be credit-worthy financial institutions. However, cash balances may
exceed FDIC insured levels at various times during the year.

    STOCK BASED COMPENSATION--The Company uses the intrinsic value method of
accounting for stock-based compensation in accordance with Accounting Principles
Board Opinion ("APB") No. 25, "Accounting for Stock Issued to Employees" and
related interpretations. See Note 14 for pro forma disclosure of net income and
earnings per share under the fair value method of accounting for stock-based
compensation as proscribed by SFAS No. 123, "Accounting for Stock-Based
Compensation".

    TRANSLATION OF FOREIGN CURRENCY--The Company translates the foreign currency
financial statements of its foreign parent in accordance with the requirements
of SFAS No. 52, "Foreign Currency Translation". Assets and liabilities are
translated at current exchange rates, and related revenues and expenses are
translated at average exchange rates in effect during the period. Resulting
translation adjustments are recorded as a separate component in stockholders'
equity. Foreign currency transaction gains and losses are included in
determining net income.

    PER SHARE OF COMMON STOCK--Per share amounts have been computed based on the
average number of common shares outstanding during the period.

                                      F-11

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    In February 1997, the FASB issued a new statement titled "Earnings Per
Share" (SFAS No. 128). This statement is effective for both interim and annual
periods ending after December 15, 1997 and specifies the computation,
presentation, and disclosure requirements for earnings per share for entities
with publicly held common stock or potential common stock. All prior-period EPS
data presented has been restated to conform to the provisions of SFAS No. 128.

    Potential common stock has been excluded from the computation of earnings
per share since the inclusion of options and warrants would be antidilutive.

NOTE 2. CORPORATE REORGANIZATION

    (a) During the period ended August 31, 1997, Benz issued 8,500,000 common
shares to acquire all of the issued and outstanding shares of Texstar (the
"Texstar Acquisition").

    As a result of this transaction the former shareholders of Texstar acquired
or exercised control over a majority of shares of Benz. Accordingly, the
transaction has been treated for accounting purposes as a recapitalization of
Texstar and, therefore, these financial statements represent a continuation of
the legal subsidiary, Texstar, not Benz, the legal parent. In accounting for
this transaction:

        (i) Texstar is deemed to be the purchaser and parent company for
    accounting purposes. Accordingly, its net assets are included in the
    consolidated balance sheet at their historical book values;

        (ii) Control of the net assets and business of Benz was acquired
    effective October 31, 1996 (the "Effective Date"). This transaction has been
    accounted for as a purchase of the assets and liabilities of Benz by Texstar
    at the fair value of $5,342,158. The historical cost of the net assets
    acquired was $4,712,162. A summary of the assigned values of the net assets
    acquired is as follows:

<TABLE>

</TABLE>

        (iii) The consolidated statements of operations and cash flows include
    Texstar's results of operations and cash flows from October 31, 1996 (date
    of inception) and Benz's results of operations from the Effective Date.

    Prior to Benz acquiring Texstar, Texstar acquired certain assets and assumed
certain liabilities from Texstar Petroleum L.L.C. ("Texstar L.L.C."), a private
company of which certain of Texstar LLC's members, directors and officers are
also shareholders, directors and officers of the Company. As a result of the
Texstar Acquisition, Texstar LLC's members are also shareholders of the Company.
Due to the fact that Texstar and Texstar LLC were under common control, the
assets and liabilities assigned have been recorded at their historical costs.

    (a) Prior to the Effective Date, Benz completed a number of agreements with
Texstar LLC whereby Benz acquired:

        (i) various working interests in five oil and gas prospects located in
    Mississippi and Texas, paid through the issuance of 2,850,000 common shares
    of Benz, at a deemed price of $1,935,800;

        (ii) an exclusive right of first refusal, at a cost of $300,000, to
    purchase 50% interests in new oil and gas properties located in the United
    States Gulf Coast areas of Texas, Louisiana and Mississippi; and

        (iii) a 32% working interest in the shallow rights and 40% working
    interest in the deep rights in the Lahinch field (the "Lahinch Prospect"),
    covering approximately 2,303 acres, located in Duval County, Texas, at a
    price of $193,506.

NOTE 3. ACQUISITIONS AND DIVESTITURES

ACQUISITIONS

    On December 29, 1998, the Company acquired, for $2.0 million, all of Mobil's
right, title and interest in the deep rights below the existing production in
the Old Ocean Unit.

    In July 1998, Benz acquired certain proved and unproved non-producing oil
and gas properties in Mississippi, Texas and Louisiana from Starbucks Trust for
$2.33 million and 600,000 shares of the Company's common stock. The purchase is
subject to certain post-closing adjustments relating to purchase value. The
value of the assets is secured through January 1, 2001, by 2.1 million shares of
the Company's common stock owned by Starbucks Trust. See Note 16, "Related Party
Transactions".

    In May 1998, the Company entered into a property swap agreement with
Southern Gas Company ("Southern Gas"). The Company conveyed to Southern Gas the
Company's entire interest in White Castle Dome (5.5%) and $1.25 million in cash.
In exchange, Southern Gas conveyed to the Company Southern Gas's entire interest
in the Oakvale, Wausau and Moselle Dome properties and prospects.


    In April 1998, the Company agreed to acquire certain petroleum interests and
assume certain liabilities from Calibre Energy, L.L.C. ("Calibre"). The Company
paid $261,000 in cash, forgave $1,450,000 in advances, assumed $450,000 in debt
and issued promissory notes totaling $2,000,000. In addition, the Company will
issue approximately 1,927,400 shares of common stock in 1999 at an ascribed
price of Cdn.$2.80 per share in connection with this transaction. These shares
have been reserved for issuance, subject to the finalization of the closing
documents.


    In January 1998, Benz acquired certain producing properties from Lasco
Energy Partners ("Lasco") for a purchase price of $15.0 million. The Company
issued a note payable which, subsequent to shareholder approval, was converted
to $12.0 million in newly authorized preferred stock (priced at $1.00) and $3.0
million in common stock (priced at $1.185). In December 1998, the Lasco purchase
price was adjusted to $12,488,140. Included in this reduction were adjustments
for the change in interest and dividends resulting from the lower purchase
price. The difference of $2,511,860 reduced the principal amount of preferred
shares to $9,488,140.


    The following unaudited pro forma financial information shows the effect on
the Company's consolidated results of operations as if the Lasco Acquisition
occurred on October 31, 1996 (Inception). The pro

DIVESTITURES

    In 1998, Benz received $1.1 million from the sale of non-strategic oil and
gas properties related to three separate transactions. During the periods ended
December 31, 1997 and August 31, 1997, the Company sold partial interests in
various unproved prospects for net proceeds of $408,931 and $416,060,

NOTE 7. PARTICIPATION AGREEMENT

    In November 1998, the Company entered into a participation agreement with
Burlington Resources International Inc. ("Burlington") to pursue government
contracts to participate in the redevelopment of oil and gas fields in Ecuador.
The Company and Burlington have participation interests of 25% and 75%,
respectively. At December 31, 1998, the Company had invested $316,470 in the
venture. Subsequent to year-end, Burlington indicated it might not renew the
agreement at this time, and that action could have an impact on the Company's
ability to maintain an interest in this region. However, the Company would
retain a 25% interest in any project related to the subject area pursued by
Burlington for one year.

NOTE 8. DRILLING ADVANCES

    As of December 31, 1998 and 1997, the Company has received drilling advances
from joint interest owners in the amounts of $20,774 and $389,348, respectively.
These advances will be applied toward the payment of drilling costs to be
incurred in the future.

    ENCAP CREDIT AGREEMENT.  The Company entered into a $20 million credit
agreement (the "EnCap Credit Agreement") with EnCap Capital Fund III, L.P.
("EnCap") consisting of a promissory note for $12,000,000 (the "Original Note")
and a promissory note for $8,000,000 (the "Supplemental Note"; collectively, the
"Notes"). The Original Note bears interest at 10% per annum up to and until
December 31, 1998 and at 18% per annum thereafter. This note is due, with
accrued interest, on July 31, 1999. The Supplemental Note was repaid in full and
no advances are currently outstanding. Under the terms of the Debentures and
Special Notes described below, the Company has agreed to limit borrowings under
the EnCap Credit Agreement to $12,000,000, all of which is outstanding. The
proceeds from the facility were applied to the acquisition of Oakvale Dome
($8,000,000), and Old Ocean properties and the drilling and completion of
certain development wells ($4,000,000). A first lien on certain properties and a
second lien on certain other properties secure the Original Note. Prentis B.
Tomlinson, Chairman and CEO of the Company, Calibre, certain affiliates of
Calibre, Slattery Trust, a private trust of which Mr. Tomlison is the
beneficiary, and Texastar Holdings, L.L.C. ("Texstar Holdings"), a private
limited liability company owned by certain directors and officers of the
Company, guarantee the Original Note.

    Under the terms of the Original Note, the Company agreed to convey to EnCap,
on January 1, 1999, a 25% net profit interest (the "EnCap NPI") from the
properties acquired with the proceeds of the

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 9. LONG-TERM DEBT (CONTINUED)
borrowing. EnCap also required Slattery Trust and Texstar Holdings (collectively
the "Benz Shareholders"), to enter into a put/call agreement (the "Put/Call
Agreement"), pursuant to which the Benz Shareholders, under certain conditions,
have the right to obtain or "call" the EnCap NPI in exchange for 1.5 million
shares of Common Shares. The Put/Call agreement also gives EnCap the right,
under certain conditions, to sell, or put, portions of the EnCap NPI to the Benz
Shareholders for an aggregate of 1.5 million shares of Common Shares as of
December 31, 1998, increasing to 3.5 million shares after March 31, 1999. The
Benz Shareholders have transferred the rights and obligations of the Put/Call
Agreement to the Company. In connection with the original granting of the EnCap
NPI, the Company recorded a discount on the Original Note of $2,102,180 as of
December 31, 1997. The discount has been amortized over the term of the Original
Note. The carrying amount of the oil and gas interests has been reduced by the
same amount. Subsequent to the end of 1998, the EnCap NPI vested and the put
option expired. Encap thus retained the NPI.

    Under the terms of the Supplemental Note, EnCap was issued warrants to
purchase up to 1.5 million shares of Common Shares at an exercise price of $1.28
per share. In connection with the issuance of these warrants, the Company
recorded a discount on the Supplemental Note of $367,881 as of December 31,
1997. This discount is being amortized over the term of the Supplemental Note
Facility. Pursuant to a financing agreement dated November 4, 1998 with EnCap
and as consideration for enabling additional funding through the Bank One Credit
Facility, the warrants were repriced to $0.46475 per share. The re-pricing did
not have material effect on the unamortized discount balance.

    BOCP CREDIT FACILITY.  In December 1998, the Company's loan agreement with
Bank One NA ("Bank One") was purchased by BOCP Energy Partners, L.P. ("BOCP").
Pursuant to an assignment of note and liens dated December 29, 1998, Bank One
assigned the original loan agreement, together with all loan documents referred
to therein, to BOCP. The principal amount then outstanding under Tranche A of
$2.9 million plus interest was repaid and, per amendments to the loan agreement,
no further advances will be requested or made under Tranche A. Interest accrued
on advances under Tranche A at prime plus 2.0%, payable monthly. The amendments
also modified the terms of Tranche B of the credit facility as follows:

        (1) Maximum availability of $6,000,000.

        (2) No advances on Tranche B will be requested or made on or after April
    30, 1999.

        (3) Maturity date of July 31, 1999.

        (4) Interest rate of prime plus eight percent per annum through and
    including December 31, 1998 and fifteen percent per annum from and after
    January 1, 1999.

    In December, the Company paid $1.5 million of the $4.5 million outstanding
principal balance under Tranche B but no interest thereon. The outstanding
balance of Tranche B as of the date of this report is $6.0 million. All interest
accrued on Tranche B remains unpaid and owing and is due on July 31, 1999. The
Company has reached a standstill agreement covering certain covenants of which
the Company is currently in violation. See Note 22, "Subsequent Events."

    SHELL FINANCING.  In December 1998, the Company entered into a financing
agreement with Shell Capital, Inc. ("Shell Capital") whereby the Company sold a
term production payment to Shell Capital for $7 million. The production payment
comprised a dedication of 42% of net revenues from the Wausau, Oak Hill, East
Morgantown properties, 23.1% of Oakvale Dome's Howell well, 12.2% of Oakvale
Dome's

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 9. LONG-TERM DEBT (CONTINUED)
Fortenberry well and 38.5% of Oakvale Dome's Byrd well. Such interests are
subject to adjustment. The production payment is secured solely by the
properties. Following full pay-out ($7.0 million plus a 15% rate of return) of
the production payment, the dedicated revenue interest is returned to the
Company less a permanent royalty interest equal to 8.75% of the Company's net
revenue interest in Wausau, Oak Hill and East Morgantown, and 4.8% of the Howell
and Byrd wells and 2.5% of the Fortenberry well. The Company has the right to
buy back the production payment at a stated rate of return of 25% plus a payment
of $1.0 million. In connection with the right to buy back the permanent
overriding royalty interest conveyance, the Company recorded a discount on the
financing of $1.0 million. The carrying amount of the oil and gas interests has
been reduced by the same amount. Shell Capital further agreed to expand its term
production payment to $25 million provided that the Company sell certain
properties, enter into a payment schedule for amounts owed to an industry
partner, raise additional capital and obtain certain minimum results from
current development drilling activity. The Company is currently negotiating with
Shell Capital and other parties to complete the expansion of the term production
payment.

    This financing has been classified as debt on the balance sheet and will be
reduced starting in 1999 as production is delivered to Shell under the terms of
the contract. Volumes delivered to Shell are reported as revenue at prices
received by Shell. Interest expense is recorded based on a rate of 15 percent.

    MOBIL FINANCING.  In December 1998, the Company obtained a short-term
advance of $2.2 million from certain investors for the purchase of Mobil's deep
rights in the Old Ocean Unit. The advances are due July 31, 1999 and bear
interest at a rate of 10% per annum.

    In connection with the short-term advance, the Company agreed to pay RP&C
International, Inc. ("RP&C") and EnCap Investments L.C. ("EnCap L.C.")
arrangement fees in the amounts of $125,400 and $6,600 respectively. In
addition, the Company granted RP&C and EnCap L.C. warrants to purchase Benz
Common Stock in an aggregate amount equal to $220,000. Such warrants were
apportioned 95% to RP&C and 5% to EnCap L.C. The exercise price of the warrants
at issuance was Cdn.$0.46 per share with an exercise period of three years. In
lieu of issuing the warrants, the Company agreed to provide RP&C and EnCap L.C.
in substance with substantially the same economic rights or interests they would
have otherwise received had they been issued the warrants. The fair value of
such right at December 31, 1998 was determined to be approximately $171,217.

    The Company also conveyed to each lender of the Mobil financing such
lender's percentage share of an overriding royalty interest equal to 50% of the
Mobil interest purchased in and to the Old Ocean Unit leases and the AMI leases.
If the Company pays in full all of the notes on or before the original maturity
date of April 30, 1999, or as extended, the lenders will re-convey the
overriding royalty interest back to the Company. The lenders have exended such
date to July 31, 1999. The Lender will retain the right to receive such lender's
percentage share of 7.75% of the net profits, if any, realized from the
production of oil, gas and other minerals from the subject interest in
connection with such re-conveyance.

    CONVERTIBLE DEBENTURES AND SPECIAL NOTES.  In March and April of 1998, the
Company completed the private placements of $27.5 million in 9% Convertible
Debentures, Series 1 general obligation notes and $10 million of 9% Special
Notes, Series A and Series B exercisable into $10 million principal amount of 9%
Convertible Debentures, Series 2 and Series 3.

    The Series 1 debentures bear interest at a rate of 9% per year payable in

subject to adjustment in certain circumstances. The debentures are redeemable in
whole or in part by the Company at any time after March 31, 2002 at the
principal amount thereof, together with any accrued but unpaid interest. The
Company may, at any time after September 30, 1999 and prior to the Maturity Date
require that all outstanding convertible debentures be converted subject to
achieving a stock price of Cdn.$2.38 per share.

    The Special Notes, Series A and Series B entitle the holder to acquire the
same principal amount of 9% convertible debentures Series 2 and Series 3, at no
additional cost, at any time on or before the earlier of (i) the fifth business
day after a final prospectus qualifying the convertible debentures to be issued

closing of the Special Notes Series A and 6 months after the closing of the
Special Notes Series B. The trustee of the Special Notes will exercise any
Special Notes not exercised prior to the above date and the convertible
debentures will be issued to the noteholders without any further action on the
part of the holder. See Note 22, "Subsequent Events".

    The convertible debentures, Series 2 and Series 3, bear interest at a rate
of 9% per annum payable in arrears in equal semi-annual installments on March
31st and September 30th of each year. The debentures have a maturity date of
August 31, 2003. The debentures will be convertible at the option of the holder
into common shares at a conversion price of Cdn.$1.70 per common share, subject
to adjustment in certain circumstances. If the holder elects to convert the
debentures prior to the date of the third semi-annual coupon, the holder will
receive a 5% premium on the number of common shares issued upon conversion. The
debentures are redeemable in whole or in part by the Company at any time after
August 31, 2002 at the principal amount thereof, together with any accrued but
unpaid interest. The Company may, at any time after August 31, 2001 and prior to
the Maturity Date require that all outstanding convertible debentures be
converted subject to achieving a stock price of Cdn.$2.13 per share.

    The Company did not receive clearance of the Special Notes in certain
Canadian jurisdictions by August 9, 1998 nor in the U.S. by September 21, 1998
and, therefore, holders of Series A Special Notes had the right to elect
retraction of up to $1.056 million in funds held in escrow pending regulatory
approval. Certain holders elected to retract a total of $988,000 plus accrued
interest. The balance was released from escrow. In addition, holders of both
Series A and Series B notes received the right to receive 10% more common shares
issued upon conversion due to not receiving clearance.

    In connection with the issuance of the Convertible Debentures, Series 1 the
Company granted the agent 2,109,974 compensation options that entitle the holder
to receive cash payment from the Company equal to the difference between the
closing market price of a common share of the Company on the trading day
immediately preceding the exercise date and Cdn.$1.70 per share, subject to
adjustment in certain circumstances. The options expire on March 25, 2000.
Pursuant to an agreement dated December 31, 1998, the options were repriced to
Cdn.$0.46 per common share. The fair value of such options was determined to be
approximately $358,577 and is being amortized over the two-year life of the
options. At December 31, 1998, $209,170 remained unamortized.

    In connection with the issuance of the Special Notes, Series A and Series B,
the Company granted the agent 737,903 special compensation warrants that entitle
the holder to acquire the same number of compensation options. The options each
entitle the holder to acquire, subject to adjustment, one common share of the
Company for Cdn.$1.70 per share at any time on or prior to April 8, 2000.

    STOCK OPTION PLAN--In 1997, the Company instituted a stock option plan (the
"Plan") covering eligible directors and employees, as defined in the Plan. The
Company may issue up to 3,020,988 shares of Common Stock under the Plan, of
which options to acquire 130,749 shares of Common Stock remained available for
grant at December 31, 1998. Such maximum includes options issued to certain
officers, directors and key employees at the discretion of the Board prior to
the adoption of the Plan. Under the Plan, the exercise price of each option
equals the market price of Benz's Common Stock on the date of grant. Options
become exercisable immediately and expire within a period determined at grant,
not to exceed ten years.

    At the February 19, 1999 meeting of the Board of Directors, 2,102,319
options held by certain employees, officers and directors of the Company were
cancelled. The Board reissued 2,112,349 options to these certain employees,
officers and directors at an exercise price of Cdn.$0.50 per share. In addition,
300,000 options held by a former officer of the Company were cancelled and
500,000 options were reissued at an exercise price of Cdn.$0.53 per share as per
his termination agreement. See Note 19, "Commitments and Contingencies" for a
discussion of the termination agreement.

    The repricing of the options is subject to VSE approval. Of the options
above, 2,023,700 options are held by executive officers and directors of the
Company and repricing of such options requires shareholder approval in addition
to VSE approval.

    The Company accounts for its stock option transactions under the provisions
of APB No. 25. The following pro forma information is based on estimating the
fair value of grants based upon the provisions of SFAS No. 123. The fair value
of each option granted during the periods indicated has been estimated as of the
date of grant using the Black-Scholes option pricing model with the following
assumptions:

NOTE 15. RETIREMENT PLAN

    The Company sponsors a 401(k) Profit Sharing Plan (the "401(k) Plan") under
Section 401(k) of the Internal Revenue Code. This plan covers all eligible
employees of the Company. The Company matches $.50 for each $1.00 of employee
deferral, subject to limitations imposed by the Internal Revenue Service.
Company contributions to the 401(k) Plan during the periods ended December 31,
1998, December 31, 1997 and August 31, 1997 totaled $75,416, $12,024 and
$23,452, respectively.

NOTE 16. RELATED PARTY TRANSACTIONS

    The Company executed a secured short-term interest-bearing note with
Starbucks Trust ("Starbucks"), a trust controlled by the wife of the Chairman &
CEO, in the amount of up to $2.5 million. The Chairman & CEO disclaims
beneficial ownership or control of the trust. Starbucks invested the funds with
brokerage accounts that used a portion of the funds to purchase the Company's
stock. Interest accrues at a rate of 9% per annum on outstanding advances. All
outstanding advances and accrued interest were due on December 31, 1998. Due to
a standstill agreement described below, at December 31, 1998 advances totaling
$2.9 million plus accrued interest remained outstanding.

    In July 1998, the Company entered into a purchase and sale agreement with
Starbucks to acquire all of Starbucks' interest in certain oil and gas leases
and properties, along with other associated assets. The purchase price was
$2,332,537 in cash and 600,000 common shares of the Company valued at $696,661,
such price subject to post-closing adjustments. Starbucks has guaranteed that
the assets acquired, on January 1, 2000 or such earlier date as Starbucks may
request, will have a value of not less than $3,032,537, such valuation defined
in the agreement. In the event the valuation is less than the amount guaranteed,
Starbucks is required to pay the difference to the Company. During 1998, the
Company paid approximately $1.1 million of the principal amount due to Starbucks
plus accrued interest. At December 31, 1998, $1.2 million remained outstanding
and is currently subject to a standstill agreement described below. The

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 16. RELATED PARTY TRANSACTIONS (CONTINUED)
Company is accruing interest on the unpaid balance due Starbucks at a rate of 9%
per annum. The Starbucks transaction was reviewed and approved by a committee of
outside directors and received approval from the Vancouver Stock Exchange.

    During 1998, the Company sold certain shares of Stanford Energy stock for
proceeds of Cdn. $1,183,735 and transferred such proceeds to Slattery Trust, a
trust controlled by Prentis B. Tomlinson. In addition, the Company transferred
certain shares of Stanford Energy stock to the account of Slattery Trust. Such
stock was subsequently sold. Proceeds from the above transactions were used by
Slattery Trust to purchase Benz Energy Ltd. common stock on the open market on
behalf of the Company. The 600,000 shares of Benz Energy common stock purchased
was then transferred to Starbucks Trust in satisfaction of the terms of the
Starbucks acquisition discussed above.

    In April 1998, the Company agreed to acquire certain petroleum interests and
assume certain liabilities from Calibre, a private limited liability company
owned by certain directors and officers of the Company, and to acquire certain
petroleum interests owned by certain directors and officers of the Company. The
Company paid $261,000 in cash, forgave $1,450,000 of Calibre accounts payable to
the Company, assumed $450,000 in debt, issued promissory notes totaling
$2,000,000 and will issue 1,927,426 shares of the Company at an ascribed price
of Cdn.$2.80 per share in 1999. The promissory notes bear interest at 10% per
annum and were due, with accrued interest, half on April 1, 1998 and the balance
on September 1, 1998. Payments of $215,000 were made during 1998 and at December
31, 1998, $1,785,000 principal amount remained outstanding plus accrued
interest. Of this amount, $1,485,000 and $200,000, due respectively to Prentis
B. Tomlinson Jr. and Starbucks Trust, are subject to a standstill agreement
described below. In addition, Mr. Tomlinson has agreed to allow amounts owed to
him under such promissory notes to be offset against the Starbucks note
receivable described above. The Caliber transaction was reviewed and approved by
a committee of outside directors and received approval from the Vancouver Stock
Exchange.

    In December 1998, as part of certain transactions by and between the Company
and Shell Capital, Inc., the Company was required to deliver an agreement
whereby Starbucks and Mr. Tomlinson each agreed to a deferment of payments of
any amounts owing to them from Benz, Texstar or any affiliate (the "Benz
Entities") until the termination date as defined in the Shell financing
arrangement. The parties agreed further not to pursue collection of any such
amounts from Benz Entities during such deferment period. Mr. Tomlinson and
Starbucks entered into such agreement in consideration of a mutual deferment by
the Benz Entities to collect or risk payments of amounts owed to them by
Tomlinson, Starbucks, Texstar Holdings L.L.C. and Security Oil, L.L.C. (See Note
9, "Long-term Debt" for a description of the Shell financing).

    Certain debt, as described in Note 9, "Long-term Debt" is guaranteed by Mr.
Tomlinson, Slattery Trust, whose beneficiary is Mr. Tomlinson, Calibre, certain
affiliates of Calibre, and Texstar Holdings.

    At August 31, 1997, the Company had advanced funds to Calibre ($453,132) and
Calibre Ecuador, Inc. ($213,187). Calibre is owned by Benz' controlling
shareholders and Calibre Ecuador, Inc. is owned 50% by Benz. The advances to
Calibre Ecuador in the amount of $213,187 have been written off as of August 31,
1997, as Calibre Ecuador has no assets or other means with which to repay the
advances. The Calibre advances bear no interest and are due upon demand.
Included in this amount is an overhead reimbursement charge to Calibre of
$66,276. This amount has been reflected in the financial statements as a
reduction of general and administrative expense.

    During the periods ended December 31, 1998, December 31, 1997 and August 31,
1997, the Company was charged $40,445, $14,250 and $106,113, respectively for
management, professional and office services provided by companies under
significant influence of former directors of the Company.

    During the period ended August 31, 1997, the Company acquired Cdn.$200,000
unsecured convertible debenture (the "Stanford Debenture") issued by Stanford.
The Stanford Debenture bore interest at a rate of 8% per annum, payable
quarterly, maturing in April 2000, and was convertible, at the option of the
Company, into 340,000 common shares of Stanford and 170,000 non-transferable
share purchase warrants. Each warrant entitled the Company to purchase an
additional flow-through common share of Stanford at Cdn.$0.60 per share,
expiring one year after issue. On August 6, 1997, the Stanford Debenture was
retired and the Company was repaid Cdn.$222,937.

    During the period ended August 31, 1997, the Company completed certain
agreements with Calibre whereby the Company:

        (i) acquired 20% working interests in each of four oil and gas prospects
    located in Mississippi, paid through the issuance of 254,863 common shares
    of the Company at a deemed price of $573,592. In addition, the Company
    reimbursed Calibre $80,000 for data costs, and

        (ii) acquired a 5.5% working interest in and to lease options, seismic
    permits and contracts relating to the White Castle field located in
    Iberville Parish, Louisiana through the issuance of 343,000 common shares of
    the Company, at a deemed price of $442,925, plus $425,000 cash, for a total
    of $867,925.

NOTE 18. GOING CONCERN ISSUE

    The accompanying consolidated financial statements have been prepared
assuming that the Company will continue as a going concern. The Company has
experienced significant delays in the completion of certain wells that are a key
component of obtaining new financing for the Company. These delays have created
a significant working capital deficit and depleted cash reserves. As a result,
the Company has secured standstill agreements on certain financial debt
covenants of which it is currently in violation. In addition, the Company was
able to extend the maturity dates of currently due debt to July 31, 1999 in
anticipation of completing a major well. In the event that the well is not
completed timely and the Company is not able to refinance the current debt by
the extended due dates, the debt may ultimately be called. The Company may not
be able to meet such demands.

    The Company anticipates the completion of the major well that is necessary
to obtain additional financing. The Company also is currently in negotiations
with several institutions to obtain production financing to repay currently due
debt. The Company also anticipates obtaining significant additional equity in
the near term through a private placement. In addition, the Company has closed
the sale of one non-core property for approximately $507,500 and is negotiating
the sale of an interest in another property for over $4.0 million of proceeds.
One additional property is currently the subject of negotiations for sale with
proceeds expected to exceed $1.0 million.

NOTE 19. COMMITMENTS AND CONTINGENCIES

    LITIGATION--The Company is involved in litigation and is subject to
governmental and regulatory controls arising in the ordinary course of business.
It is the opinion of the Company's management that all claims and litigation
involving the Company are not likely to have a material adverse effect on its
financial position or results of operations.

    The Company has filed suit against STB Energy Inc., Hilton Petroleum, Inc.,
Trimark Resources, Inc., Westport Petroleum, Inc. and Bradley M. Colby alleging
breach or participation and operating agreements, suit on a sworn account,
fraudulent inducement to contract, fraud, constructive fraud, breach of
fiduciary duty and conspiracy, and seeks a declaratory judgement on corporate
veil and alter ego theories. The suit is pending and trial date has been set.

    The Company has filed suit against Rainbow Oil and Gas, Inc. ("Rainbow")
alleging breaches of participation, operating and letter agreements covering
certain prospects in Texas, Louisiana, and Mississippi. Rainbow counter-claimed
and seeks relief in the form of damages for breach of contract, fraud and
punitive damages plus attorneys' fees and interest. The lawsuit is presently in
the initial stages of discovery.

NOTE 19. COMMITMENTS AND CONTINGENCIES (CONTINUED)
Although the outcome of this lawsuit can not be predicted with certainty,
management will vigorously defend the counterclaims and believes that such
counterclaims will not have a material adverse effect on the financial position
or results of operations of the Company.

    ENVIRONMENTAL--Benz, as owner and operator of oil and gas properties, is
subject to various federal, state, and local laws and regulations relating to
discharge of materials into, and protection of, the environment. These laws and
regulations may, among other things, impose liability on the lessee under and
oil and gas lease for the cost of pollution clean-up resulting from operations,
subject the lessee to liability for pollution damages and impose restrictions on
the injection of liquids into subsurface strata. Benz maintains insurance
coverage that it believes is customary in the industry, although it is not fully
insured against all environmental risks.

    The Company is not aware of any environmental claims existing as of December
31, 1998, that would have a material impact on its financial position or results
of operations. There can be no assurance, however, that current regulatory
requirements will not change, or past non-compliance with environmental laws
will not be discovered on the Company's properties.

    TERMINATION AGREEMENTS--The Company terminated a key officer's employment
without cause and requested such officer to resign all of his positions with the
Company except his position as a Director of the Company. As defined in his
employment contract with the Company, such officer was entitled to certain
liquidated damages, and not as a penalty, in the amount of $1,150,000 payable as
follows:

    - Payments of $10,000 per month for 12 months commencing February 15, 1999;

    - Payment of $400,000 on January 15, 2000;

    - Payment of $200,000 on July 15, 2000; and

    - Payment of the balance due under his agreement, as adjusted, on January
      15, 2001.

    In addition, the officer was granted new stock options in lieu of the
300,000 shares granted December 18, 1997. The new stock option agreement dated
February 15, 1999 is for 500,000 shares of Common Shares $0.01 par value. The
remaining agreed liquidated damages due on January 25, 2001 shall be reduced by
the difference between the option price under the new option agreement for
500,000 shares of Common Shares and the 500,000 option shares as of the date the
payment of the balance of the agreed liquidated damages. All cash payments
payable to the officer shall be reduced by applicable federal, state and local
withholding taxes. As a Director to the Company, he will be provided the same
Director's Liability Insurance provided to other Directors. The Company also
agreed that at its sole cost and expense to continue current health insurance
coverage as required by applicable law until January 5, 2000; however, he
notified the Company that he would forfeit such coverage as of April 15, 1999
and resigned as a director of the Company.

    On December 16, 1998, the Company entered into an agreement with EnCap that,
should Mr. Tomlinson's employment be terminated, except for cause, following
certain events, then EnCap on behalf of the Company will make a cash payment to
Mr. Tomlinson of $1.0 million within 30 days of severance, and the Company will
enter into a consulting agreement with a three-year term providing for payments
of $185,000 per annum, and grant Mr. Tomlinson a permanent overriding royalty
interest in certain properties. These payments are obligations of the Company
and EnCap has agreed to provide financing to fund such payment obligations.

NOTE 21. FINANCIAL INSTRUMENTS

    The Company's financial instruments consist of cash, accounts receivable,
accounts payable and long-term debt. The carrying amounts of cash, accounts
receivable and accounts payable approximate fair value due to the highly liquid
nature of these short-term instruments. The long-term debt, excluding the
convertible debentures and special notes, approximates fair value due to the
revision of terms at year-end of the bank indebtedness and the EnCap facility
and the closing at year end of the Mobil promissory notes and the Shell
production payment, all at current terms available to the Company. The
convertible debentures and special notes approximate fair value based on the
fact that holders elected to maintain the current terms when offered the ability
to modify such terms.

    - The Company executed the Sixth through Ninth Amendments to the BOCP Credit
      Facility wherein the maturity of such facility was changed to July 31,

      these amendments.

    - Certain holders of the convertible debentures ($7,050,000) elected to be
      paid for the six-month period ending March 31, 1999 with 1,057,500 shares
      of common stock in lieu of $315,000 of interest. The stock price used in

      Company's proven oil and gas properties and is scheduled to be repaid
      through a dedicated portion of property income. Terms of the financing
      include a 12% interest rate and an assignment of 1/16th interest in the

NOTE 23. CUSTOMER INFORMATION

    MAJOR PURCHASERS--During the year ended December 31, 1998, H&N Gas Ltd. "H&N
Gas" and Tejas Gas Marketing Co. accounted for approximately 51% and 24%,
respectively, of the Company's total oil and gas revenue. For the four-month
period ended December 31, 1997, H&N Gas and KCS Resources ("KCS") accounted for
75% and 10%, respectively, of the Company's total oil and gas revenue. For the
ten months ended August 31, 1997, KCS, Samaden Oil Corporation and Energy
Operating Limited Partnership accounted for 50%, 30% and 18%, respectively, of
the Company's total oil and gas revenue. No other purchasers accounted for more
than 10% of the Company's total oil and gas revenue in the periods indicated
above. The Company does not believe the loss of any existing purchaser would
have a material adverse effect on the Company.

    CONCENTRATION OF CREDIT RISK--The Company's revenues are derived principally
from uncollateralized sales to customers in the oil and gas industry; therefore,
customers may be similarly affected by changes in economic and other conditions
within the industry. Benz has not experienced significant credit losses on such
sales.

    IMPACT OF PRICING--The estimates of cash flows and reserve quantities shown
above are based on year-end oil and gas prices, except in those cases where
future gas sales are covered by contracts at specified prices. Estimates of
future liabilities and receivables applicable to oil and gas commodity hedges
are reflected in future cash flows from proved reserves with such estimates
based on prices in effect as of the

date of the reserve report. Fluctuations are largely due to supply and demand
perceptions for natural gas and volatility in oil prices.

    Under SEC rules, companies that follow full cost accounting methods are
required to make quarterly "ceiling test" calculations. Under this test,
capitalized costs of oil and gas properties may not exceed the present value of
estimated future net revenues from proved reserves, discounted at 10 percent,
plus the lower of cost or market value of unproved properties, as adjusted for
related tax effects and deferred income taxes. Application of these rules
generally requires future production to be priced at the unescalated oil and gas
prices in effect at the end of each fiscal quarter and requires a write-down if
the "ceiling" is exceeded, even if prices declined for only a short period of
time.

                        INDEPENDENT ACCOUNTANT'S REPORT

To the Board of Directors and Stockholders
  Benz Energy Inc.

We have reviewed the accompanying consolidated balance sheets of Benz Energy
Inc. as of March 31, 1999 and 1998 and the related consolidated statements of
operations, comprehensive income, stockholders' equity and cash flows for the
three-month periods then ended. These financial statements are the
responsibility of the Company's management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants. A review of interim financial
information consists principally of applying analytical procedures to financial
data and making inquiries of persons responsible for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with generally accepted auditing standards, the objective of which is the
expression of an opinion regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the accompanying financial statements for them to be in conformity
with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 17 to the
financial statements, the Company has experienced significant delays in the
completion of certain wells and its limited capital resources raise substantial
doubt about its ability to continue as a going concern. Management's plans in
regard to these matters are also described in Note 17. The financial statements
do not include any adjustments that might result from the outcome of this
uncertainty.

                                  (UNAUDITED)

    These financial statements have been prepared by Benz Energy without audit,
pursuant to the rules and regulations of the Securities and Exchange Commission,
and reflect all adjustments that are, in the opinion of management, necessary
for a fair statement of the results for the interim periods, on a basis
consistent with the annual audited financial statements. All such adjustments
are of a normal recurring nature. Certain information, accounting policies, and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been omitted
pursuant to such rules and regulations, although the Company believes that the
disclosure are adequate to make the information presented not misleading. These
financial statements should be read in conjunction with the financial statements
and the summary of significant accounting policies and notes thereto included
elsewhere in this Prospectus.

1. DEBT

    At June 30, 1999, the Company had outstanding debt of $63.1 million
comprised of the following:

    - $36.3 million principal amount of convertible debentures of which
      approximately $15.1 million was converted into Class A Series II preferred
      stock in July 1999;

    - $12.0 million principal amount outstanding under the EnCap Credit Facility
      due, by amendment, on July 31, 1999;

    - $6.0 million principal amount outstanding under the BOCP Credit Facility
      due, by amendment, on July 31, 1999;

    - $2.2 million principal amount outstanding under the Old Ocean loan.
      Repayment of the outstanding balance was made through the issuance of
      Class A Series II preferred stock in July 1999;

    - $5.5 million, net of discount, due Shell Capital, Inc.; and

    - $1.1 million advanced by certain lenders who invested additional capital
      in the Company through the exchange offering in July 1999.

    The Company repaid the EnCap Credit Facility and the BOCP Credit Facility
with funds obtained in connection with the Aquila production payment financing
discussed below and a new note with EnCap in the amount of $2.5 million. Such
note matures December 31, 2000 and accrues interest at a rate of 10% per annum.

2. ACQUISITIONS AND DIVESTITURES

    In January 1999, the Company acquired on behalf of the Company and its
partner in the Wausau prospect, a gas pipeline in Mississippi for approximately
$425,000 to provide access for gas sales. Included in the purchase were a 100%
and a 93.75% BPO working interest in two producing wells. The Company does not
anticipate these wells reaching payout. The Company owns a 53.8% interest in the
pipeline and the Fairchild #1 well and a 50.5% interest in the A. Foote Estate
#1 well. Gas reserves net to the Company are estimated to be in excess of 150
MMCFG and net production of over 150 MCFGPD.

    In May 1999, the Company sold its interest in the Lisbon Field, comprising
essentially all of its proven reserves in Louisiana, for $507,500 in gross
proceeds to an unrelated party.

7. SUBSEQUENT EVENTS

    On July 9, 1999, the Company consummated an offering pursuant to which it
offered to exchange up to 354,250 shares of its class A, series II preferred
stock for any and all of its outstanding 9% convertible debentures series I, due
March 31, 2003 and an offering to sell up to 121,000 shares of class A, series
II convertible preferred stock. At the closing, the Company exchanged
$15,145,000 principal amount of the 9% convertible debentures for 159,201 shares
of class A, series II preferred stock and issued 44,600 shares under the primary
offering. In addition the Company issued 34,596 shares of class A, series II
convertible preferred stock and warrants to purchase 3,974,923 shares of common
stock in connection with the retirement of 95.45% of the Old Ocean loan and the
re-conveyance of the applicable net profits interest. The balance of the Old
Ocean financing and re-conveyance was settled through a cash payment. The
remaining proceeds from the exchange offer and the offering of convertible
preferred stock were used to pay a portion of the seismic costs relating to the
old Ocean Prospect and to pay fees and expenses of the transactions. The
preferred stock issued has a dividend rate of 8% payable semi-annually on
September 30th and March 31st in cash or common stock at the election of the
Company. The conversion price is Cdn. $0.35 per share. The Company has the right
to redeem the preferred stock in cash at any time upon thirty days notice at
105% of the principal amount.

    On July 12, 1999 the Company conducted a meeting with its trade creditors to
outline a proposed repayment plan for past due amounts. Such plan included
proposed discounts, payment over an extended time and other payment terms. As of
August 23, 1999, creditors approached regarding these arrangements elected to
participate in the repayment plan representing 90% of past due amounts for an
aggregate of $11.2 million in past due amounts.

    In August, the Company sold a 37.5% interest in its Old Ocean prospect to
Prime Natural Resources, Inc. Prime paid $3.5 million at closing and will pay an
additional $1,978,098 on or before September 15 in consideration of the interest
purchased. The Company reserved an overriding royalty interest in all leases and
contractual rights to volumes of production and all similar interests, whether
currently owned or acquired later, within the established area of mutual
interest for the project. Prime has an option for a six months period to
purchase an additional 12.5% of the Company's interest in the Old Ocean
prospect, subject to the overriding royalty reservations set forth above, at a
purchase priced of $1,826,033, plus $214,276 at the end of the six month period.
The Company has agreed to enter into an agreement under which Prime or one of
its affiliates will have the right to market the 3-D seismic geophysical data
covering the Old Ocean prospect for a ten year period following a 120 day
exclusivity period that the Company retained. Prime will be entitled to the
Company's share of the proceeds from the sale of the date, which share may be no
less than 66 2/3%, subject to applicable sales commissions. In addition, Prime
or its affiliate must grant the Company a license to other geophysical data
outside the Old Ocean prospect owned by Prime or its affiliate. The Company may
select the outside data of its choice covering up to 102 square miles.

    Also in August 1999, the Company closed a new long-term production financing
facility with Aquila Energy Capital Corporation in the initial amount of $26.2
million. The facility may be extended by up to $1.5 million based on results of
well stimulation work in the Fortenberry well. The proceeds were used to retire
existing senior secured debt and accrued interest including the Shell production
financing, the EnCap Credit Facility and the BOCP Credit facility. In addition,
the Company has a firm commitment from Aquila for an additional $3.8 million of
funding for development drilling at its Oakvale Dome Field.

properties and is repaid through a dedicated portion of the property income.
Terms of the financing include a 12% interest rate and assignment of 1/16th of
the Company's interest in the proven properties following full repayment of the

Stock, Series I to investment entities affiliated with and managed by EnCap
Investments, L.C. The Company paid a placement fee of $100,000 to EnCap

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 24. INDEMNIFICATION OF DIRECTORS AND OFFICERS.


    The Delaware General Corporation Law (the "DGCL") grants every corporation
the power to indemnify any person who was or is a party or is threatened to be
made a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative, or investigative (other than an action
by or in the right of the corporation) by reason of the fact that he is or was a
director, officer, employee, or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee, or agent of
another corporation, partnership, joint venture, trust, or other enterprise. The
indemnity may include expenses (including attorneys' fees) judgments, fines, and
amounts paid in settlement actually and reasonably incurred by him in connection
with such action, suit, or proceeding, if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.



    The DGCL also grants every corporation the power to indemnify any person who
was or is a party or is threatened to be made a party to any threatened,
pending, or completed action or suit by or in the right of the corporation to
procure a judgment in its favor by reason of the fact that he is or was a
director, officer, employee, or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust, or other enterprise
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection with the defense or settlement of such action or suit if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interest of the corporation and except that no
indemnification shall be made in respect of any claim, issue, or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnification for such expenses which the
court shall deem proper.



    The DGCL provides that to the extent that a present or former director or
officer of a corporation has been successful on the merits or otherwise in
defense of any action, suit, or proceeding referred to in the statute, or in the
defense of any claim, issue, or matter therein, he shall be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection therewith.


    The Registrant's Certificate of Incorporation contains provisions which
indemnify and exculpate the directors and officers of the Registrant from and
against certain liabilities. The Registrant's Certificate of Incorporation
provides that each person who at any time is or was a director or officer of the
Registrant, and is threatened to be or is made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,

ITEM 28. UNDERTAKINGS

(1) To file, during any period in which offers or sales are being made, a
    post-effective amendment to this Registration Statement:

     (i) To include any prospectus required by section 10(a)(3) of the
         Securities Act of 1933;

     (ii) To reflect in the prospectus any facts or events arising after the
          effective date of the registration statement (or the most recent
          post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in this registration statement;

    (iii) To include any material information with respect to the plan of
          distribution not previously disclosed in this registration statement
          or any material change to such information in this registration
          statement; provided, however, that subparagraphs (i) and (ii) do not
          apply if the information required to be included in a post-effective
          amendment by those paragraphs is contained in the periodic reports
          filed by the Registrant pursuant to Section 13 or Section 15(d) of the
          Securities and Exchange Act of 1934 that are incorporated by reference
          in this registration statement.

(2) That for the purpose of determining any liability under the Securities Act
    of 1933, each such post-effective amendment shall be deemed to be a new
    registration statement relating to the Securities offered herein, and the
    offering of such Securities at that time shall be deemed to be the initial
    bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of
    the Securities being registered which remain unsold at the termination of
    the offering.

                                      II-6

    The undersigned Registrant hereby undertakes:

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to officers, directors and controlling persons of the
Registrant pursuant to the provisions described under Item 24 of this
registration statement, or otherwise, the Registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in such Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a trustee,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such trustee, officer or controlling
person in connection with the Securities being registered, the Registrant will,
unless in the opinion of our counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is public policy as expressed in such Act and will be
governed by the final adjudication of such issue.

Section 2.  DIVIDENDS

         The holders of the Series II Preferred Stock will be entitled to
receive dividends at the Designated Rate. Such dividends will be prior and in
preference to any declaration or payment of any dividends paid on Junior
Stock. Dividends on the Series II Preferred Stock will be cumulative and will
accrue whether or not declared and whether or not there will be funds legally
available for the payment thereof. The dividends shall be payable
semi-annually in arrears on March 31 and September 30 of each year (the
"Dividend Payment Date") commencing on September 30, 1999, except that if any
such date is not a Business Day, then such dividend shall be payable on the
first Business Day immediately thereafter to holders of records as they
appear on the stock register of the Corporation on the applicable record
date, which shall be September 15 or March 15, as the case may be,
immediately preceding the relevant Dividend Payment Date. The dividend shall
be payable in cash (U.S. Dollars), except as otherwise provided in the next
paragraph. Dividends payable on the Series II Preferred Stock for each full
semi-annual dividend period shall be computed by dividing the annual payment
by two. Dividends payable on the Series II Preferred Stock for any period
that is shorter or longer than full semi-annual dividend period shall be
computed on the basis of a 360-day year of two 180 day semi-annual periods.

         The Board of Directors of the Corporation may, at least 30 days
prior to the subject Dividend Payment Date, elect to pay the cash dividend in
Common Stock (a "Payment in Kind") provided that the Common Stock received is
Freely Tradable upon receipt by the recipients of such shares. If such an
election is properly made, the Corporation shall at least 30 days prior to
payment notify the holders of record of the Series II Preferred Stock
entitled to such dividend of the election to make a Payment in Kind in lieu
of a payment in cash for the subject Dividend Payment Date. An election for
any particular Dividend Payment Date shall operate only for such Dividend
Payment Date. Each Payment in Kind shall be payable as of the Dividend
Payment Date for which the election to make such Payment in Kind was made,
except that if such Dividend Payment Date is not a Business Day, then such
Payment in Kind shall be on the first Business Day immediately thereafter to
holders of record as they appear on the stock register on the applicable
record date. Each Payment in Kind shall be equal to that number of shares of
Common Stock that is equal in number to the aggregate cash dividend payable
on the subject Dividend Payment Date (disregarding deductions for withholding


                                      -5-
<PAGE>

taxes, if any, under all applicable Laws (including applicable income tax
treaties)) divided by the Dividend Market Price.

         Common Stock issuable on payment of any Payment in Kind shall be
delivered to each holder entitled to such Payment in Kind or to their order
within 10 days following the Dividend Payment Date for which such Payment in
Kind is elected to be made hereunder.

         All dividends payable on the Series II Preferred Stock shall be paid
net of withholding tax, if any, under all applicable Laws (including
applicable income tax treaties). The Corporation will, subject to certain
exceptions and limitations set forth below, pay, as additional dividends,
such additional amounts (the "Additional Amounts") to the holder of any
Series II Preferred Stock as may be necessary in order that every net payment
of the principal or dividends on such Series II Preferred Stock, after
withholding for or on account of any present or future tax, duty, assessment
or governmental charge imposed or levied upon or as a result of such payment
by or on behalf of the United States (or any political subdivision, authority
or agency thereof or therein having the power to tax) (collectively, "Taxes"),
will not be less than the amount such holder would have received if such Taxes
had not been withheld, provided that no Additional Amounts will be payable
with respect to a payment which is subject to such Taxes by reason of such
holder being connected with the United States (or any political subdivision
thereof) otherwise than by the mere holding of the Series II Preferred Stock
or the receipt of payments made under or with respect to the Series II
Preferred Stock. In addition, the Corporation will indemnify and hold
harmless each holder of the Series II Preferred Stock (subject to the
exclusion set forth above) and will, upon written request of each holder
(subject to the exclusion set forth above), and provided that reasonable
supporting documentation is provided, reimburse each other holder for the
amount of any Taxes levied or imposed by the United States and paid by or on
behalf of the holder as a result of payments made under or with respect to
the Series II Preferred Stock. Any payment made pursuant to this paragraph
shall be considered an Additional Amount. If the Corporation becomes
generally subject at any time to any taxing jurisdiction other than  or in
addition or the United States, references in this Certificate of Designation
to the United States shall be read and construed as reference to the United
States and/or to such other jurisdiction.

         Dividends on account of arrears for any past dividend period may be
declared and paid at any time without reference to any regular Dividend
Payment Date, to holders of record on a date not more than a forty-five (45)
calendar days prior to the payment thereof, as may be fixed by the Board of
Directors of the Corporation.

Section 3.  LIQUIDATION PREFERENCE

         In the event of any liquidation, dissolution or winding up of the
Corporation, voluntary or involuntary, the holders of the Series II Preferred
Stock will be entitled to receive in preference to the holders of the Common
Stock and Junior Stock a cash amount in U.S. Dollars equal to U.S. S105 per
share plus any dividends accumulated on the Series II Preferred Stock but not
paid (the "Liquidation Amount"). In the event of a consolidation or merger of
the Corporation with or into


                                      -6-

<PAGE>

any other entity or a sale or transfer in a single transaction or series of
related transactions of all or substantially all of the assets of the
Corporation, then the holders of the Series II Preferred Stock shall have the
right (but not the obligation) to treat the merger as a liquidation of the
Corporation and require the Corporation to deliver the Liquidation Amount in
cash to any holder of the Series II Preferred Stock making such an election.

     Written notice of any payment to the holders of Series II Preferred
Stock as as result of the liquidation, dissolution or winding-up of the
Corporation, stating the payment date or dates when and the place or places
where the amounts distributable in such circumstances shall be payable, shall
be given by first-class mail, postage prepaid, not less than thirty (30) days
prior to any payment date stated therein, to the holders of record of the
Series II Preferred Stock at their respective addresses as the same shall
appear on the books of the transfer agent for the Series II Preferred Stock
("Company Registrar").

Section 4.    CONVERSION RIGHT

     Each holder of Series II Preferred Stock will have the right, subject as
provided herein and to any applicable Laws and regulations, at any time at
the holder's option to convert any or all of the Series II Preferred Stock
into Common Stock at a conversion price (subject to adjustment as described
below) through March 31, 2000 of Cdn$0.35 (the "Preferred Conversion Price").
The number of shares of Common Stock issuable on conversion pursuant to this
Section 4 shall equal the total nominal value of all of the Series II
Preferred Stock converted, divided by the then applicable Preferred
Conversion Price.  If on March 31, 2000, the average of the Market Prices
during the preceding twenty (20) consecutive Stock Exchange Business Days is
lower than the Preferred Conversion Price, the Preferred Conversion Price
will be adjusted downward to the average of the Market Price during the
preceding twenty (20) consecutive Stock Exchange Business Days as determined
on March 31, 2000.  The Corporation will ensure that within four months after
the effective date of the issuance of the Preferred Stock ("Four Month
Period"), any Common Stock issued on conversion of the Series II Preferred
Stock or as dividends will be Freely Tradable.  If the Common Stock to be
received is not Freely Tradable by such date, then the Preferred Conversion
Price shall be permanently reduced by 5% for each six month period or portion
thereof commencing on the expiration of the Four Month Period until the
Corporation is in a position to deliver Common Stock in connection with any
such Conversion or as dividends that is Freely Tradable.  In addition, the
Corporation will ensure that by the expiration of the Four Month Period, the
holders of the Series II Preferred Stock have Series II Preferred Stock that
are Freely Tradable.  If the Corporation has not satisfied the foregoing
requirements by the expiration of the Four Month Period, then the Preferred
Conversion Price shall be permanently reduced by 5% for each six month period
or portion thereof commencing on the expiration of the Four Month Period
until the Corporation has satisfied the foregoing requirements with respect
to the Series II Preferred Stock.  No fractional shares of Common Stock will
be issued upon conversion but, the number of shares will be rounded to the
nearest whole number.  Upon the conversion of any Series II Preferred Stock,
payment will be made by the Corporation for dividends accrued during the
period from the most recent dividend payment date to the conversion date
(which for the purpose of calculating payment shall be deemed to be the


                                     -7-
<PAGE>

date such payment is made).  Upon the conversion of any Series II Preferred
Stock for Common Stock as permitted hereunder, payment for dividends accrued
during the period from the most recent dividend payment date to the
conversion date may be made in Freely Tradable Common Stock or cash, at the
Corporation's option.  Such payment or delivery shall be made within sixty
(60) days following conversion.

     In order to exercise the conversion right, the holder of each share of
Series II Preferred Stock to be converted shall comply with the procedures
for conversion as provided by The Depository Trust Company ("DTC"), New York,
New York and the DTC participant holding the Series II Preferred Stock on
behalf of the holder and shall give written notice to the Corporation in the
form of EXHIBIT A attached hereto.  Such notice shall also state the name or
names (with address) in which the shares of Common Stock which shall be
issuable upon such conversion shall be issued.  Each share surrendered for
conversion shall, unless the shares issuable on conversion are to be issued
in the same name as the name in which such shares of the Series II Preferred
Stock is registered, be duly endorsed by, or be accompanied by, instruments
of transfer (in each case, in form reasonably satisfactory to the
Corporation), duly executed by the holder or such holder's duly authorized
attorney-in-fact.

     As promptly as practicable after the surrender of the shares of the
Series II Preferred Stock for conversion and the receipt of such notice as
aforesaid, the Corporation shall issue and shall deliver to such holder, or on
such holder's written order, the number of shares of Common Stock issuable
upon the conversion of such shares of the Series II Preferred Stock in
accordance with the provisions of this paragraph.

Section 5.    CORPORATION CONVERSION OPTION

     The Corporation may, at its option, cause the Series II Preferred Stock
to be converted into Common Stock at the then Preferred Conversion Price at
any time after March 31, 2000, provided (i) the average Market Price of the
Common Stock for twenty (20) consecutive Stock Exchange Business Days
commencing on or after March 31, 2000 and ending not more than five (5) days
prior to the giving of such notice, has equaled or exceeded 140% of the then
Preferred Conversion Price and (ii) the Common Stock to be received is Freely
Tradable.  The Corporation is required to give thirty (30) days advance
notice in writing to the holders of the Series II Preferred Stock that it has
elected such a mandatory conversion.

      The Corporation may, at its option, redeem the Series II Preferred
Stock at any time for a cash price equal to the Liquidation Amount.
Commencing April 1, 2003, at the option of the Corporation, the Corporation
may redeem the Series II Preferred Stock for Common Stock (provided such
Common Stock is Freely Tradable) with a value of (i) 115% of the nominal
amount if the market capitalization of the Corporation is $300 million or
more on such date, or (ii) 120% of the nominal amount if the market
capitalization is less than $300 million on such date.  The Common Stock so
issued shall be valued at the average of the Market Price for the Common
Stock for the 20

                                     -8-

<PAGE>

consecutive Stock Exchange Business Days ending five Stock Exchange Business
Days prior to the date of payment as notified in the notice.

     The Corporation must give thirty (30) days prior notice of any such
election of conversion or cash redemption. During any such 30-day notice
period holders of the Series II Preferred Stock will retain the right to
exercise their conversion rights as to such Series II Preferred Stock.  Upon
any election by the Corporation to convert or redeem any Series II Preferred
Stock pursuant to the terms set forth in this Section 5, payment for
dividends accrued during the period from the most recent dividend payment
date to the conversion date or redemption date will be made by the
Corporation in cash, or if the Series II Preferred Stock are converted into
Common Stock, then in Freely Tradable Common Stock. Such dividends shall be
paid or delivered within sixty (60) days following conversion. Upon the
expiration of any such notice period as is referred to above, the Corporation
shall be bound to redeem or convert the Series II Preferred Stock as to which
notice has been provided pursuant to this Section 5 and holders of such
Series II Preferred Stock have not, by that date, converted such shares.

Section 6.     ISSUANCE OF COMMON STOCK

     Each conversion with respect to the Series II Preferred Stock shall be
deemed to have been effected immediately prior to the close of business on
the date on which the shares of the Series II Preferred Stock shall have been
effectively surrendered to the Company Registrar and the Person or Persons
entitled to receive the Common Stock issuable upon such conversion shall be
deemed for all purposes to be the record holder or holders of such Common
Stock upon that date. The Corporation shall pay any and all documentary,
stamp or similar issue or transfer taxes payable in respect of the issue or
delivery of the Common Share issued in payment of dividends or in exchange or
conversion of the Series II Preferred Stock.

     The Corporation shall reserve out of its authorized but unissued Common
Stock or its Common Stock held in treasury enough Common Stock to permit the
conversion of all of the outstanding Series II Preferred Stock. The
Corporation shall from time to time, in accordance with applicable Law,
increase the authorized amount of its Common Stock if at any time the
authorized amount of its Common Stock remaining unissued shall not be
sufficient to permit the conversion of all shares of the Series II Preferred
Stock at the time outstanding. If any Common Stock required to be reserved
for issuance upon conversion of the Series II Preferred Stock hereunder
require registration with or approval of any governmental authority under any
applicable Law before the shares may be issued upon conversion, the
Corporation shall cause the shares to be so registered or approved. All
Common Stock delivered upon conversion of the Series II Preferred Stock or
for the payment of dividends due hereunder will, upon delivery, be Freely
Tradable, duly authorized and validly issued, fully paid and nonassessable,
free from all taxes, liens and charges with respect to the issue thereof.

     (d)       if the Corporation or any Material Subsidiary shall fail to pay
          its Debts as such Debts come due (except Debts which the Corporation
          or such Material Subsidiary, as the case may be, may contest in good
          faith generally) and such failure could reasonably be expected to have
          a material adverse effect on the business, assets, or the ability of

          years ending (i) December 31, 1998 and 1999, falls below 100% of Long
          Term Debt at any time,

<PAGE>

          or (ii) after December 31 1999, falls below 140% of Long Term Debt at
          any time. This ratio shall be calculated no later than the 135th day
          following the end of each of the Corporations's fiscal years, and
          shall be based upon the Corporation's annual audited financial
          statements (as adjusted for Tangible Assets) and the Independent
          Reserve Reports; or

Section 10.    CONVERSION PRICE ADJUSTMENTS

     The Preferred Conversion Price for any Series II Preferred Stock in effect
at any date shall be subject to adjustment from time to time as follows:

     (a)       If, and whenever at any time any shares of the Series II
          Preferred Stock remain outstanding, the Corporation shall (i)
          subdivide or redivide the outstanding Common Stock into a greater
          number of shares, (ii) reduce, combine or consolidate the outstanding
          Common Stock into a smaller number of shares, or (iii) issue Common
          Stock or other securities convertible into or exchangeable for Common
          Stock to the holders of all or substantially all of the outstanding
          Common Stock by way of a stock dividend (other than the issue of
          Common Stock to holders of Common Stock pursuant to their exercise of
          options to receive dividends in the form of Common Stock in lieu of
          dividends paid in the ordinary course on the Common Stock), the
          Preferred Conversion Price in effect on the effective date of such
          subdivision, redivision, reduction, combination or consolidation or on
          the record date for such issue of Common Stock by way of a stock
          dividend, as the case may be, shall be adjusted by multiplying the
          Preferred Conversion Price then in effect by a fraction the numerator
          of which is the number of shares of Common Stock outstanding
          immediately prior to such event and the denominator is the number of
          shares of Common Stock outstanding immediately following such event.
          Such adjustment shall be made successively whenever any event referred
          to in this subsection (a) shall occur; any such issue of Common Stock
          by way of a stock dividend shall be deemed to have been made on the
          record date for the stock dividend for the purpose of calculating the
          number of outstanding shares of Common Stock under subsections (c) and
          (d) of this Section 10.

     (b)       If, and whenever at any time any shares of the Series II
          Preferred Stock remain outstanding, shares of Common Stock are
          reclassified into different shares any holder of Series II Preferred
          Stock who has not exercised his right of conversion prior to the
          effective date of such reclassification shall be entitled to receive
          and shall accept, upon the exercise of such right or upon his being
          required to do so at anytime on or thereafter, in lieu of the number
          of shares of Common Stock to which he was theretofore entitled upon
          conversion, the aggregate number of shares of the


                                         -13-

<PAGE>

         Corporation that such holder would have been entitled to receive as a
         result of such reclassification if on the effective date thereof, he
         had been then the registered holder of the number of shares of Common
         Stock to which he was theretofore entitled upon conversion, subject to
         adjustment thereafter in accordance with provisions the same, as nearly
         as may be possible, as contained in this Section 10.

(c)               If, and whenever at any time any shares of the Series II
         Preferred Stock remain outstanding, the Corporation shall fix a record
         date for the issuance of rights or warrants to all or substantially all
         the holders of its outstanding Common Stock entitling them to subscribe
         for or purchase Common Stock or shall issue Common Stock other than
         to officers and directors or any employee bonus or option plan (or
         securities exchangeable for or convertible into Common Stock), in
         either case at a price per share (or having a conversion or exchange
         price per share) less than 95% of the then current Market Price on such
         record date, the Preferred Conversion Price shall be adjusted
         immediately after such record date so that it shall equal the price
         determined by multiplying the Preferred Conversion Price in effect on
         such record date by a fraction, of which the numerator shall be the
         total number of shares of Common Stock outstanding on such record date
         plus a number of shares of Common Stock equal to the number of
         additional shares of Common Stock that the aggregate of the proceeds
         to be realized from the issuance of the rights or warrants so offered
         (for the aggregate conversion or exchange price of the convertible
         securities so offered) would purchase at the then current Market Price,
         and of which the denominator shall be the total number of shares of
         Common Stock outstanding on such record date plus the total number of
         additional shares of Common Stock offered for subscription or purchase
         (or into which the convertible securities so offered are convertible):
         any Common Stock owned by or held for the account of the Corporation
         shall be deemed not to be outstanding for the purposes of any such
         computation; such adjustments shall be made successively whenever such
         a record date is fixed; to the extent that any such rights or warrants
         are not so issued or any such rights or warrants are not exercised
         prior to the expiration thereof, the Preferred Conversion Price shall
         be readjusted to the Preferred Conversion Price which would then be
         in effect if such record date had not been fixed or to the Preferred
         Conversion Price which would then be in effect based upon the number of
         shares of Common Stock (or securities convertible into Common Stock)
         actually issued upon the exercise of such rights or warrants, as the
         case may be, provided that this subsection (c) of Section 10 will not
         apply to adjust the Preferred Conversion Price if each holder of Series
         II Preferred Stock is permitted to participate in the receipt and
         exercise of such rights or warrants as though such holder had converted
         the whole of his Series II Preferred Stock in accordance with this
         Section 10 prior to such record date.

(d)               If, and whenever at any time any shares of the Series II
         Preferred Stock remain outstanding the Corporation shall fix a record
         date for the making of a


                                      -14-
<PAGE>

     distribution to all or substantially all the holders of its outstanding
     Common Stock of (i) shares of my class other than Common Stock and other
     than shares distributed to holders of Common Stock pursuant to their
     exercise of options to receive dividends in the form of such shares in
     lieu of dividends paid in the ordinary course on the Common Stock and
     other than shares issued upon any subdivision of Common Stock referred to
     in subsection (a) of this Section 10 or (ii) rights, options, or warrants
     (other than those referred to above) or of evidences of indebtedness or
     of assets (excluding cash dividends paid in the ordinary course) than, in
     each such case, the Preferred Conversion Price shall be adjusted
     immediately after such record date so that it shall equal the price
     determined by multiplying the Preferred Conversion Price in effect on such
     record date by a fraction, of which the numerator shall be the total
     number of shares of Common Stock outstanding on such record date
     multiplied by the current Market Price, less the fair market value (as
     determined by the board of directors with the approval of the Trustee,
     which determination shall be conclusive) of such shares or rights,
     options or warrants or evidence of indebtedness or assets so
     distributed, and of which the denominator shall be the total number of
     shares of Common Stock outstanding on such record date multiplied by such
     current Market Price; any Common Stock owned by or held for the account
     of the Corporation shall be deemed not to be outstanding for the purpose
     of any such computation; such adjustment shall be made successively
     whenever such a record date is fixed; to the extent that such Distribution
     is not so made, the Preferred Conversion Price shall be readjusted to the
     Preferred Conversion Price which would then be in effect if such record
     date had not been fixed or this Preferred Conversion Price which would
     then be in effect based upon such shares or rights or warrants or evidences
     of indebtedness or assets actually distributed, as the case may be; in
     this subsection (d) the term "dividends paid in the ordinary course" shall
     include the value of any securities or other property or assets
     distributed in lieu of cash dividends paid in the ordinary course at the
     option of the shareholders, provided that this subsection (d) of Section
     10 will not apply to adjust the Preferred Conversion Price if each holder
     of Series II Preferred Stock is permitted to participate in such
     Distribution as though such holder had converted the whole of his Series
     II Preferred Stock in accordance with this Section 10 prior to such record
     date.

(e)       In case of any reclassification of, or any other material change
     in, the outstanding Common Stock of the corporation other than a
     subdivision, redivision, reduction, combination or consolidation, the
     Preferred Conversion Price shall be adjusted in such manner as the board
     of directors, acting reasonably and in good faith determined to be
     appropriate on a basis consistent with the Section 10.

(f)       If and whenever at any time any shares of the Series II Preferred
     Stock remain outstanding, there is a capital reorganization of the
     Corporation not covered by the foregoing provisions of this Section 10 or
     a consolidation or merger or amalgamation of the Corporation with or
     into any other company including by way of a sale


                                     -15-
<PAGE>

     whereby all or substantially all of the Corporation's undertaking and
     assets would become the property of any other company, and a holder of
     Series II Preferred Stock who has not exercised his right of conversion
     prior to the effective date of such reorganization, consolidation,
     merger, amalgamation or sale, shall be entitled to receive and shall,
     subject to the provisions hereof, accept, upon the exercise of such right
     at any time on such effective date of thereafter, in lieu of the number
     of shares of Common Stock to which he was therefore entitled upon
     conversion, the aggregate number of shares or other securities of
     property of the Corporation or of the company resulting from the
     consolidation, merger or amalgamation or to which such sale may be made,
     as the case may be, that such holder would have been entitled to
     receive as a result of such capital reorganization, consolidation,
     merger, amalgamation or sale if, on the effective date thereof, he had
     been the registered holder of the number of shares of Common Stock to
     which he was theretofore entitled upon conversion, subject to
     adjustment thereafter in accordance with provisions the same, as nearly
     as may be possible, as contained in this Section 10.

(g)       In any case in which this Section 10 shall require that an adjustment
     shall become effective immediately after the record date for an event
     referred to herein, the Corporation may defer until the occurence of
     such event, issuing to the holder of any Series II Preferred Stock
     converted after such record date and before the occurence of such event
     the additional shares of Common Stock issuable upon such conversion by
     reason of the adjustment required by such event before giving effect to
     such adjustment; provided, however, that the Corporation shall deliver to
     such holder an appropriate instrument evidencing such holder's right to
     receive such additional shares of Common Stock upon the occurence of the
     event requiring such adjustment and the right to receive any
     distributions made on such additional Common Stock declared in favor of
     holders of record of Common Stock on and after the Date of Conversion or
     such later date as such holder would, but for the provisions of this
     subsection (g), have become the holder of record of such additional
     shares of Common Stock.

(h)       The adjustments provided for in this Section 10 are cumulative and
     shall apply, without duplication, to successive subdivisions,
     redivisions, reductions, combinations, consolidations, distributions,
     issues or other events resulting in any adjustment under the provisions
     of this section, provided that, notwithstanding any other provision of
     this Section, no adjustment of the Preferred Conversion Price shall be
     required unless such adjustment would require an increase or decrease of
     at least 1% in the Preferred Conversion Price then in effect; provided
     however, that any adjustment which by reason of this subsection (h) are
     not required to be made shall be carried forward and taken into account
     in any subsequent adjustment.

     In the event of any question arising with respect to the adjustments
provided in this Section 10, such question shall be conclusively determined by
a nationally recognized firm of


                                     -16-
<PAGE>

independent public accountants appointed by the Corporation (who may be the
auditors of the Corporation); such accountants shall have access to all
necessary records of the Corporation and such determination shall in the
absence of manifest error be binding upon the Corporation and the holders of
the Series II Preferred Stock.

Section 11.   PAYMENTS

     All cash payments shall be by check to the address as set out on the
books of the Company or the Company Registrar.  Any payments or values that
need to be converted into U.S. dollars or Canadian Dollars shall be converted
based upon the Exchange Rate as of the date five (5) Stock Exchange Business

dollars or Canadian dollars, as the case may be, quoted by The Bank of Nova
Scotia at approximately noon (Toronto, Canada time) on such date if it is a
Business Day or on the immediately preceding Business Day if such date is not

of the Series II Preferred Stock shall be deemed given when deposited in the
United States mail, postage prepaid, and addressed to such holder of record at
his or her address appearing on the books of the Corporation.  Unless

         directors of Benz and any preferred shares of Benz entitle to vote for
         the election of directors of Benz upon the satisfaction of certain
         conditions, and the "beneficial ownership" of Voting Securities shall
         be determined in accordance with Rule 13d-3 under the U.S. Securities

2.        Borrower has requested that EnCap III LP consent to Borrower's sale of
          a dollar denominated production payment for $10,000,000 prior to
          December 31, 1998, upon the terms described in the term sheet attached
          hereto as Exhibit C, burdening only those properties with respect to
          which Bank One presently has a first lien to secure the Bank One
          Credit Facility. EnCap III LP hereby gives such consent, provided
          that: (a) the other terms of such production payment, and the terms of
          any subordination requested from EnCap III LP with respect to its
          second lien on such properties, are satisfactory to EnCap III LP in
          the reasonable exercise of its discretion, (b) concurrently with such
          sale the EnCap Credit Agreement is amended to replace the references
          to the Bank One Credit Facility in Sections 7.1(b) and 7.2(b) thereof
          with references to such production payment, (c) a portion of the
          proceeds from the sale of such production payment are used to repay in

          Borrower agrees to use the remainder of such proceeds only for the
          purposes described in Exhibit F hereto.

          (a)   Benz covenants, agrees, represents and warrants that, until
                January 1, 2001:

                (i)     Neither Benz nor Texstar will enter into any new
                        financial commitments of more than $50,000 without
                        approval of the Benz Board of Directors (excluding any
                        existing contractual commitment and any commitment
                        entered into in the future to deal with well blowouts
                        and other operational emergencies), provided that such
                        approval may be given generally for particular projects
                        rather than on an item-by-item basis. Neither Benz nor
                        Texstar will enter into any transactions any of the
                        other Guarantors/Shareholders without approval of the
                        Benz Board of Directors. In connection with their
                        resolutions authorizing this letter agreement, the Board
                        of Directors of Benz has adopted standing resolutions
                        providing for the foregoing.

                (ii)    The authorized size of Benz's Board of Directors on the
                        date hereof is six persons, and the Board has the
                        authority to appoint up to two additional directors.
                        Benz agrees not to increase the size of the Board to
                        more than seven. Benz has six incumbent directors, who
                        are Prentis B. Tomlinson, Jr., Robert L. Zorich, Yale
                        Fisher, Ernest LaFlure, Robert Herlin, and L. E. Walker.

                (iii)   A true and correct copy of its articles of incorporation
                        and bylaws, as amended to date, are attached hereto as
                        Exhibits H and I.

                (iv)    Prior to the occurrence of a Stakeholder Election, as
                        defined below, EnCap III LP will be entitled to have
                        Gary Petersen or Marty Phillips (in addition to Robert
                        L. Zorich) attend and observe any meeting of the Benz or
                        Texstar Board of Directors.

                (v)     As soon as reasonably possible hereafter, Benz will
                        cause its bylaws (or, in the case of the following
                        subparagraph (1), its articles of incorporation) to be
                        amended to provide that until January 1, 2001:

                        (1)      The size of the Board will be fixed at seven
                                 directors (rather than the current
                                 arrangement allowing the size of the Board
                                 to vary between three and ten).

                        (2)      Board decisions will be made by a majority
                                 of the board members, provided that (A)
                                 sales or acquisitions of assets for more
                                 than $5,000,000, sales of substantially all
                                 assets, sales of equity or of rights to
                                 acquire equity, bankruptcy filings, new
                                 financings, changes to the size or
                                 composition of the Executive Committee of
                                 Benz's Board, and recommendations to the
                                 shareholders with respect to mergers will
                                 require the affirmative vote of 60% or more
                                 of the directors, (B) all votes of the
                                 Executive Committee of Benz's Board will be
                                 required to be unanimous, and (C) amendment
                                 or elimination of the requirements of the
                                 foregoing clauses (A) or (B) will require
                                 the affirmative vote of all directors or
                                 approval of Benz's shareholders.

                        (3)      Board approval will be required for (A) new
                                 financial commitments of more than $50,000
                                 (excluding any existing contractual
                                 commitment and any commitment entered into
                                 in the future to deal with well blowouts and
                                 other operational emergencies), provided
                                 that such approval may be given generally
                                 for particular projects rather than on an
                                 item-by-item basis, and (B) transactions
                                 between Benz and Texstar or between either
                                 Benz or Texstar and any of the other
                                 Guarantors/Shareholders.

                  Benz has consulted with its Canadian counsel and has been
                  informed that the above changes to its bylaws can all be
                  properly made by Benz's existing Board of Directors,
                  provided that such changes will be effective only until the
                  next meeting of Benz's shareholders, at which time such
                  changes will cease to be effective unless ratified by the
                  shareholders. Benz shall present such changes to its bylaws
                  and articles of incorporation to Benz's shareholders for
                  ratification and adoption at

                  or before its next scheduled shareholders meeting, and in no
                  event later than February 28, 1999.

         (b)      Benz covenants, agrees, represents and warrants that it has
                  obtained executed letters from Robert Herlin and L. E. Walker
                  (the "Director Resignations), true and correct copies of which
                  are attached hereto as Exhibit D, that Benz has not yet
                  accepted or rejected the Director Resignation from Robert
                  Herlin and that Benz has accepted the Director Resignation
                  from L. E. Walker.

         (c)      Benz covenants and agrees that it will, provided an Oakvale
                  Drilling Success has occurred, accept the Director
                  Resignations immediately upon request that it do so made by
                  EnCap LC prior to January 1, 2001. Any such request by EnCap
                  LC after the occurrence of an Oakvale Drilling Success is
                  herein called a "Stakeholder
                  Election".

         (d)      Benz warrants and covenants that if a Stakeholder Election
                  occurs, its Board of Directors (who have approved this
                  letter agreement) will immediately appoint to the Board (i)
                  one EnCap Designee (as defined below) and (ii) two Debenture
                  Holder Designees (as defined below), provided that the same
                  have been designated, to fill the vacancies arising from the
                  Director Resignations and to hold the position of a seventh
                  director. As used herein, the term "EnCap Designee" means a
                  person designated by EnCap LC, the term "Debenture Holders"
                  means the holders of Benz's largest issue (at each time in
                  question) of outstanding unsecured debt securities (which
                  currently is Benz's 9% Convertible Debentures, Series 1 due
                  March 31, 2003), and the term "Debenture Holder Designee"
                  means a person designated by a majority of the Debenture
                  Holders.

         (e)      Benz warrants and covenants that, with respect to any vote of
                  the Benz shareholders or the Benz Board of Directors that
                  occurs after a Stakeholder Election and prior to January 1,
                  2001, concerning the election or appointment of persons to
                  serve on its Board of Directors:

                  (i)  Benz's Board of Directors will nominate for election
                       to the Board, or appoint to the Board, two EnCap
                       Designees, two Debenture Holder Designees, and three
                       persons designated by the Guarantors/Shareholders
                       other than Benz and Calibre (the "Guarantor/
                       Shareholder Designees"), provided that the same have
                       been designated and further provided that at least one
                       Guarantor/Shareholder Designee must be an independent
                       director not associated or affiliated with the
                       Guarantor/Shareholders, EnCap LC, or the Debenture
                       Holder Designees (the "Independent Nominee").

                  (ii) Benz will use its best efforts to cause the EnCap
                       Designees, the Debenture Holder Designees, and the
                       Guarantor/Shareholder Designees to be elected or
                       appointed to the Benz Board of Directors.

                  The independence of the Independent Nominee must be consented
                  to by EnCap LC, which consent may not be unreasonably
                  withheld. EnCap LC hereby consents to Yale Fisher as the
                  Independent Nominee.

         (f)      Each Guarantor/Shareholder covenants and agrees that it
                  will use its best efforts to cause Benz to comply with its
                  covenants and agreements contained in this paragraph 3.
                  Each Guarantor/Shareholder and Lasco covenants and agrees
                  that it will support the nomination and election of the
                  EnCap Designees, the Debenture Holder Designees and the
                  Guarantor/Shareholder Designees to Benz's Board of
                  Directors. Each Guarantor/Shareholder and Lasco covenants
                  and agrees that, with respect to any vote of the Benz
                  shareholders that occurs after a Stakeholder Election and
                  prior to January 1, 2001, concerning the election of
                  persons to serve on Benz's Board of Directors:

                  (i)  It (i.e., such Guarantor/Shareholder or Lasco) will
                       vote or cause to be voted all Voting Securities
                       beneficially owned by it in favor of the election of
                       the EnCap Designees, the Debenture Holder Designees,
                       and the Guarantor/Shareholder Designees to Benz's
                       Board of Directors, provided that the same have been
                       designated, and in favor of any merger or sale
                       requiring shareholder consent which has been approved
                       by the affirmative vote of 60% or more of Benz's
                       Directors.

                  (ii) It will, upon request made by EnCap LC after a
                       Stakeholder Election has occurred, enter into a Voting
                       Agreement substantially in the form attached as
                       Exhibit G hereto, providing for the granting of an
                       irrevocable proxy to an unaffiliated bank or trust
                       company chosen by EnCap LC to vote such
                       Guarantor/Shareholder's or Lasco's shares as provided
                       herein. The Guarantors/Shareholders can sell up to a
                       total of 20% of the aggregate number of shares of Benz
                       common stock held by the Guarantor/Shareholders on the
                       date the Voting Agreement is executed without the
                       assignee or transferee being subject to the terms of
                       the Voting Agreement. If, however, the
                       Guarantors/Shareholders sell any shares of Benz common
                       stock that exceed such amount, the assignee or
                       transferee of such shares must agree to be subject to
                       the terms of this letter agreement and the Voting
                       Agreement as a condition to the sale.

                 (iii) Such Guarantor/Shareholder and Lasco will otherwise
                       use its best efforts to cause the EnCap Designees, the
                       Debenture Holder Designees and the Guarantor/Shareholder
                       Designees to be elected to Benz's Board of Directors.

         (g)     Benz, each Guarantor/Shareholder and Lasco warrants and
                 agrees that, in the event of the death, incapacity,
                 resignation or removal of an EnCap Designee, a Debenture
                 Holder Designee or a Guarantor/Shareholder Designee after a
                 Stakeholder Election and prior to January 1, 2001,
                 preventing his or her serving on the Benz Board of
                 Directors, it will promptly use its best efforts to cause
                 the election or appointment of another EnCap Designee,
                 Debenture Holder Designee or Guarantor/Shareholder Designee
                 (as applicable) to fill the vacancy created thereby.

         (h)     Each Guarantor/Shareholder represents and warrants to BOCP
                 that as of the date hereof such Guarantor/Shareholder is the
                 record and beneficial owner of the number of shares of
                 Common Shares of Benz, no par value per share, set forth
                 opposite its name in Exhibit E attached hereto.

4.       BOCP, EnCap III LP and EnCap LC consent to Benz and Texstar entering
         into an employment agreement with Prentis B. Tomlinson, Jr., providing
         for the following benefits if Mr. Tomlinson's employment is ever
         terminated except for "cause" (as hereafter defined):

         (a)  a $1,000,000 cash severance payment, payable within 30 days after
              termination;

         (b)  a consulting contract with a term of three years after
              termination, providing for Mr. Tomlinson to receive payments of
              $185,000 per annum and to devote a substantial portion of his
              time, as requested, to assisting Benz and Texstar with their
              oil and gas activities, restricting Mr. Tomlinson from
              competing with Benz and Texstar with respect to their active
              oil and gas prospects during such period, and requiring Mr.
              Tomlinson to hold in confidence all confidential, proprietary,
              non-public information at any time in his possession concerning
              Benz or Texstar or their properties or prospects; and

         (c)  the grant of an overriding royalty interest equal to 1%,
              proportionately reduced to Texstar's working interest in
              Texstar's Oakvale, LaHinch, and Rayburn/Plum Grove properties,
              and equal to a .25% net revenue interest (calculated on an
              8/8ths basis), in Texstar's Old Ocean properties (subject in
              each case to all liens, burdens and encumbrances on Texstar's
              title at such time and reduced by the amount of any royalties
              already existing on such properties in favor of Mr. Tomlinson,
              his

              family members, or any Guarantors/Shareholders other than Benz
              or Texstar, excluding only an overriding royalty of
              approximately .38% presently owned by Heather Tomlinson in the
              Oakvale Dome properties.

     BOCP, EnCap III LP and EnCap LC further consent to Texstar granting the
     foregoing overriding royalties to Mr. Tomlinson at any time. Regardless of
     when such overriding royalties are granted, if a Stakeholder Election
     occurs and thereafter Mr. Tomlinson's employment with Benz is terminated by
     Benz (except for cause) prior to January 1, 2001, then BOCP and EnCap III
     LP will release any liens which they may have on such overriding royalties
     at the time of such termination. As used in this paragraph 4 and the
     following paragraph 5, "cause" means any of the following: (i) a material
     failure of Mr. Tomlinson to follow or comply with any lawful directive of
     the requisite majority of the Benz Board of Directors; (ii) a material
     failure of Mr. Tomlinson to perform his duties as the chief executive
     officer of Benz; (iii) conduct by Mr. Tomlinson which constitutes an act of
     fraud, theft, dishonesty, or violation of any statutory or common law duty
     of loyalty to Benz; (iv) Mr. Tomlinson's conviction of a felony or any
     crime of moral turpitude, or (v) Mr. Tomlinson's unreasonable absence from
     employment without excuse or justification.

5.   EnCap III LP agrees that, if a Stakeholder Election occurs and thereafter
     Mr. Tomlinson's employment with Benz is terminated by the shareholders or
     Board of Directors of Benz (except for cause) prior to January 1, 2001,
     then EnCap III LP will make the cash severance payment to Mr. Tomlinson
     described in paragraph 4(a) above on behalf of Benz if Benz fails to make
     such payment within 30 days after becoming obligated to do so. If EnCap III
     LP makes such payment after Benz fails to do so, such payment will be
     deemed an advance to Texstar under the EnCap Credit Agreement that is
     secured by all liens and security interests given by Texstar to EnCap III
     LP, and Texstar and Benz will immediately reimburse EnCap III LP for the
     amount of such payment. EnCap III LP's obligation to make such payment on
     behalf of Benz will not be affected by Benz or Texstar having inadequate
     funds to make such reimbursement, but EnCap III LP will not be obligated to
     make such payment if Benz or Texstar is, at the time in question, in
     bankruptcy proceedings, and EnCap III LP's obligation will also be limited
     by any affirmative defense, offset or other limitation on Benz's obligation
     to Mr. Tomlinson. At such time as a Stakeholder Election occurs, Benz and
     Texstar will execute such instruments as EnCap III LP may reasonably
     request to more fully provide for the foregoing.

6.   Borrower will, on or before December 31, 1998, amend its articles of
     incorporation to provide that no bankruptcy or insolvency proceedings can
     be initiated on behalf of Borrower without the express consent of at least
     two-thirds of its shareholders of record. At the same time, Benz will amend
     its bylaws to provide that no such consent will be

Page 10


     given with respect to Borrower except upon the affirmative vote of 60% or
     more of Benz's directors.

7.   If and when the EnCap Designee (other than Robert L. Zorich) and the two
     Debenture Holder Designees become members of the Benz Board of Directors,
     each Guarantor/Shareholder (other than Benz, Calibre, and Benz Properties
     Ltd.) shall be deemed automatically released from any personal liability
     under its respective guaranty agreement executed in favor of EnCap III LP
     (although any pledges of its stock in Benz or Benz's subsidiaries or
     affiliates will remain in effect), and EnCap III LP and each such
     Guarantor/Shareholder will execute appropriate instruments to confirm such
     release and confirm that such pledges remain in effect, but without
     personal liability to such Guarantor/Shareholder. At the same time,
     Borrower, Benz, Calibre and Benz Properties Ltd. will consent to such
     instruments and ratify and confirm their obligations under the Loan
     Documents. Prior to the time, if any, that such automatic releases occur,
     EnCap III LP will not enforce such guaranty agreement against such
     Guarantor/Shareholder (other than Benz, Calibre, and Benz Properties Ltd.)
     until 180 days after EnCap III LP has either (a) commenced enforcement of
     its remedies against Texstar under one or more Loan Documents following the
     occurrence of an "Event of Default" under the EnCap Credit Agreement or (b)
     been stayed from commencing such enforcement, provided that EnCap III LP
     shall not be prevented from filing any claim or otherwise acting to
     preserve its rights under such guaranty agreement from becoming
     unenforceable due to any statute of limitations, filing deadline or similar
     requirement.

8.   BORROWER AND THE GUARANTORS/SHAREHOLDERS -- ON BEHALF OF THEMSELVES AND, TO
     THE EXTENT THEY ARE PERMITTED BY LAW OR ARE OTHERWISE EXPRESSLY AUTHORIZED
     TO DO SO, ON BEHALF OF ALL OTHER BENZ ENTITIES -- HEREBY RATIFY AND CONFIRM

     THAT ANY RELEASED CLAIMS WITH RESPECT TO ANY INVESTOR ENTITY HAVE NOT BEEN
     RELEASED BY THIS LETTER AGREEMENT, BORROWER AND THE GUARANTORS/SHAREHOLDERS
     HEREBY ASSIGN SUCH RELEASED CLAIMS TO SUCH INVESTOR ENTITY.

10.  Borrower, the Guarantors/Shareholders, BOCP and EnCap III LP hereby ratify
     and confirm the arbitration provisions of the November Letter Agreement.
     Borrower ratifies and confirms its agreement in the November Letter
     Agreement to provide to EnCap III LP and to Bank One, within five business

     month. Benz agrees to provide BOCP and Bank One with similar schedules, at
     the same times, with respect to Benz and its subsidiaries other than
     Borrower.

11.  Borrower and the Guarantor/Shareholders agree that no payments of any kind
     (whether repayments of debt, fees for services, or otherwise) will be made
     by Borrower or Benz to any Shareholder/Guarantor other than Benz, provided
     that Benz may make salary payments to Prentis Tomlinson of up to $16,667
     per month (and may accrue additional salary payments of up to $5,450 per
     month provided that such accrued salary may not be paid until the earlier
     of January 1, 2002 and the termination of the EnCap Credit Agreement.) The
     EnCap Credit Agreement is hereby amended by deleting the last two sentences
     of Section 7.5 thereof.

<PAGE>

                          P R O M I S S O R Y   N O T E

$10,000,000.00                                                    July 17, 1997

         FOR VALUE RECEIVED, after date, without grace, in the manner, on the
dates and in the amounts so herein stipulated, the undersigned, TEXSTAR
PETROLEUM, INC., a Texas corporation ("Borrower"), PROMISES TO PAY TO THE
ORDER OF BANK ONE, TEXAS, N.A., a national banking association ("Lender"), in
Houston, Harris County, Texas, the sum of TEN MILLION AND NO/100 DOLLARS
($10,000,000.00) or, if less, the aggregate unpaid principal amount of
advances made by Lender to Borrower pursuant to this Promissory Note (this
"Note"), in lawful money of the United States of America, which shall be
legal tender in payment of all debts and dues, public and private, at the
time of payment, and to pay interest on the advanced and unpaid principal
amount from date until maturity at a rate equal to the Base Rate (hereinafter
defined) plus two percent (2%) per annum ("Stated Rate"), not to exceed the
maximum non-usurious interest rate permitted by applicable law from time to
time in effect as such law may be interpreted, amended, revised, supplemented
or enacted ("Maximum Rate"), provided that if at any time the Stated Rate
exceeds the Maximum Rate then interest hereon shall accrue at the Maximum
Rate. In the event the Stated Rate subsequently decreases to a level less
than the Maximum Rate or if the Maximum Rate applicable to this Note should
subsequently be increased to a level greater than the Stated Rate, then, in
either case, interest hereon shall thereafter accrue at a rate equal to the
applicable Maximum Rate until the aggregate amount of interest accrued
through the term of this Note equals the aggregate amount of interest which
would have accrued at the Stated Rate without regard to any usury limit, at
which time interest hereon shall again accrue at the Stated Rate.

         This Note is payable as follows:

                   1.  Accrued and unpaid interest shall be due and
         payable on the first day of each month, commencing
         August 1, 1997.

                   2.  All accrued and unpaid interest and unpaid
         principal shall be due and payable on June 30, 2000.

All payments under this Note shall be applied first against the accrued and
unpaid interest hereon and the remainder against the principal balance hereof.

         This Note is subject to mandatory prepayments, as set forth in the
Loan Agreement (hereinafter defined). In addition, Borrower may prepay this
Note, in whole or in part, at any time prior to maturity without penalty, and
interest shall cease on any amount

prepaid. Any partial prepayment shall be applied toward the payment of the
principal installments last maturing on the Note, that is, in the inverse
order of maturity, without reducing the amount or time of payment of the
remaining installments.

         Any check, draft, money order or other instrument given in payment
of all or any part hereof may be accepted by Lender and handled in collection
in a customary manner, but same shall not constitute payment hereof or
diminish any rights of Lender except to the extent that actual cash proceeds
of such instrument are unconditionally received by Lender.

         It is agreed that time is of the essence of this agreement. In the
event of default in the payment of any installment of principal or interest
when due or in the event of any other default hereunder, Lender may
accelerate and declare this Note immediately due and payable without notice.
Any failure to exercise this option shall not constitute a waiver by Lender
of the right to exercise the same at any other time.

         In the event of default in the making of any payment herein
provided, either of principal or interest, or in the event this Note is
declared due, interest hereunder shall accrue at the Maximum Rate.

         Borrower hereby agrees to pay all expenses, including reasonable
attorneys' fees, all of which shall become a part of the principal hereof,
incurred by Lender if this Note is placed in the hands of an attorney for
collection or if collected by suit or through any probate, bankruptcy or any
other legal proceedings.

         Interest charges will be calculated on amounts advanced hereunder on
the actual number of days the amounts are outstanding on the basis of a
365-day or 366-day year, as is applicable.

         It is expressly stipulated and agreed to be the intent of Borrower
and Lender to comply with applicable Texas law governing the maximum
non-usurious rate or amount of interest payable on or in connection with this
Note (or applicable United States federal law to the extent that it permits
Lender to contract for, charge, take, reserve or receive a greater amount of
interest than under Texas law). Accordingly, it is agreed that
notwithstanding any provision to the contrary in this Note, or in any of the
documents securing payment hereof or otherwise relating hereto, no such
provision shall require the payment or permit the collection of interest at a
rate in excess of the Maximum Rate. If any excess of interest in such respect
is provided for, or shall be judicially interpreted to be so provided for, in
this Note or in any of the documents securing payment hereof or otherwise
relating hereto, or if the acceleration of the maturity of this Note or any
prepayment by Borrower results in Borrower's having paid any interest in
excess of that permitted by applicable law, then in any such event,

it is the express intent of Borrower and Lender that (1) the provisions of
this paragraph shall govern and control, (2) neither Borrower nor any other
person primarily liable on this Note, nor their respective heirs, legal
representatives, successors or assigns, shall be obligated to pay the amount
of such interest to the extent that it is in excess of the Maximum Rate, (3)
any such excess which may have been collected shall be either applied as a
credit against the then unpaid amount hereof or refunded to Borrower, and (4)
the provisions of this Note and any documents securing payment of this Note
shall be automatically deemed reformed and the amounts thereafter collectible
thereunder reduced, without the necessity of the execution of any new
document, so that the effective rate of interest shall be reduced to the
Maximum Rate. For the purpose of determining the maximum amount of interest
permitted to be charged or collected hereunder, all sums paid or agreed to be
paid to Lender for the use, forbearance or detention of the proceeds of this
Note shall be amortized, prorated, allocated and spread throughout the full
term of this Note so that the rate or amount of interest on account of this
Note is uniform throughout the term hereof and does not exceed the applicable
usury ceiling.

         Borrower agrees that the Maximum Rate to be charged or col lected
pursuant to this Note shall be the indicated rate ceiling referred to in TEX.
REV. CIV. STAT. ANN. Art. 5069-1.04, provided that Lender may rely on other
applicable laws, including without limitation laws of the United States, for
calculation of the Maximum Rate if the application thereof results in a
greater Maximum Rate. Except as provided above, the provisions of this Note
shall be governed by the laws of the State of Texas.

         Borrower and each other person who is a maker, surety, guarantor or
endorser of this Note hereby waives demand, grace, notice, presentment for
payment, notice of intention to accelerate the maturity hereof, notice of the
acceleration of the maturity hereof and protest, and agrees that this Note
and the liens securing its payment may be renewed, and the time of payment
extended, from time to time, without notice and without releasing any of the
foregoing. As additional security for all amounts owed by Borrower to Lender,
Borrower hereby grants to Lender a lien and security interest on (and the
express right of setoff against) any of Borrower's funds which may from time
to time be deposited with or in the possession of Lender.

         As used in this Note, the term "Base Rate" shall mean at any time
the variable rate of interest then most recently announced publicly by Lender
(or any successor to all or substantially all of its assets) as its base rate
of interest and, without notice to Borrower or any other person, such rate of
interest shall change as and when changes in that base rate of interest are
announced.

         The principal of this Note represents funds which Lender may advance
to Borrower, pursuant to and subject to the Loan Agreement, from time to time
upon request of Borrower. Any part of the principal may be repaid by Borrower
and thereafter reborrowed, provided the outstanding principal amount of this
Note shall never exceed the face amount of this Note. Each advance shall
constitute a part of the principal hereof and shall bear interest from the
date of the advance. The provisions of Tex. Rev. Civ. Stat. Ann. art.
5069-15.01, ET. SEQ., as the same may be amended, shall not apply to this
Note or to any of the Security Documents.

L.L.C. secured by the existing liens on such oil and gas properties of
Borrower, including the indebtedness pursuant to the above-described
$750,000.00 Promissory Note, and the liens securing the payment of such note,
which burden the interests acquired by Borrower, are not released, but are
hereby ratified and hereby carried forward to secure this Note.

Gentlemen:

     This letter loan agreement (this "Agreement") confirms the mutual
agreements between TEXSTAR PETROLEUM, INC., a Texas corporation ("Borrower"),
and BANK ONE, TEXAS, N.A., a national banking association ("Lender"), in
connection with a credit facility more fully described herein.

     Section 1. CREDIT FACILITY. Subject to the terms of this Agreement,
Lender agrees to lend and Borrower agrees to borrow certain amounts pursuant
to the following terms and conditions (the "Credit Facility"):

         (a) NOTE: Borrower's obligation to repay the Credit Facility shall be
    evidenced by its execution of a promissory note (the "Revolving Note") of
    even date herewith, payable to the order of Lender, in the original
    principal amount of Ten Million and No/100 Dollars ($10,000,000.00), and
    in the form attached as Exhibit "A" attached hereto.

         (b) MAXIMUM AVAILABILITY: The lesser of $10,000,000.00 and the
    Borrowing Base (as defined in Section 5(c) hereof).

         (c) ADVANCE PROCEDURES: At least one (1) Business Day (hereinafter
    defined) prior to the requested date of advance (other than the initial
    advance being made on the date hereof), Borrower may make a written request
    to Lender for direct advances pursuant to the Credit Facility. Prior to the
    requested date of advance, Lender shall advise Borrower of whether Lender
    will make the advance as requested by Borrower or whether Lender will
    require additional engineering reports or other documents prior to making
    the requested advance.

         (d) TERM: Through June 30, 2000 (the "Maturity Date").

         (e) PURPOSE: To finance certain costs associated with the
    acquisition and development of Borrower's oil and gas properties included
    in the determination of the Borrowing Base.

         (f) FACILITY FEE: Borrower shall pay to Lender a facility fee in the
    amount of $5,000 plus two percent (2%) of any



<PAGE>

Bank One, Texas, N.A.

    increase in the Borrowing Base over $750,000.00 upon the effectiveness
    of such increase.

         (g) UNUSED FEE: Borrower shall pay to Lender an unused fee in an
    amount equal to one-half percent (1/2%) of the average unused portion of
    the Borrowing Base, payable in arrears on the last day of each calendar
    quarter.

         (h) BORROWING BASE REDETERMINATION FEES: Borrower shall pay to
    Lender a fee of $2,500.00 for the initial determination of the Borrowing
    Base and, with respect to each redetermination of the Borrowing Base,
    Borrower shall pay a like amount to Lender for all engineering and
    related expenses (including a reasonable charge for services performed by
    employees of Lender or affiliates of Lender) incurred by Lender in
    connection with such redetermination.

    Section 2. INTEREST RATE AND REPAYMENT TERMS.

    (a) INTEREST RATE.

        (1) Subject to the provisions of paragraphs (2) and (3) of this
    Section 2(a), Borrower shall pay interest on the outstanding principal
    amount of the Revolving Note at two percent (2%) per annum over the Base
    Rate. Accrued and unpaid interest on the Revolving Note shall be
    calculated on the basis of a 365-day year of 366-day year, as the case
    may be, and the actual number of days elapsed.

        (2) In the event that, and for so long as, any event of default
    hereunder shall have occurred and be continuing, then and in any such
    event, the outstanding principal amount of the Revolving Note shall bear
    interest at the Maximum Rate (as defined in the Revolving Note).

        (3) Notwithstanding anything contained herein to the contrary, in no
    event shall the interest rate payable with respect to the Revolving Note
    exceed the Maximum Rate.

    meanings:

            (A) "Business Day" shall mean a day other than a Saturday,
    Sunday, or legal holiday for commercial banks under the laws of the

               (B)  "Base Rate" shall mean at any time the variable rate of
          interest then most recently announced publicly by Lender (or any
          successor to all or substantially all of its assets) as its base
          rate of interest and, without notice to Borrower or any other
          person, such rate of interest shall change as and when changes in
          that base rate of interest are announced.

shall be due and payable on August 1, 1997, and on the first day of each
month thereafter.  The principal portion of the Revolving Note is subject to

unpaid principal and accrued and unpaid interest on the Revolving Note shall
be due and payable on the Maturity Date.

     Borrower in Lender's possession.  Borrower has no litigation and there
     is no legal or administrative proceeding, investigation or other action

     involves the possibility of any judgment or liability not fully covered
     by insurance.

          (d)  TITLE.  Borrower has good title to its assets and properties,

     applicable laws and regulations.

     limited to any reportable event or prohibited transaction (as defined

     Regulations G, U, or X of the Board of Governors of the Federal Reserve

and workable condition at all times.  Borrower will perform all obligations
under this Agreement, and under all indentures, agreements, and contracts by
which Borrower is bound.  Borrower will maintain with financially sound and
reputable insurers acceptable to Lender, insurance with respect to its
properties and business against such liabilities, casualties, risks and
contingencies as is customary for its business naming Lender as loss payee
with respect to any insurance covering collateral securing the loans
hereunder, and will, upon Lender's request, provide satisfactory evidence of
such insurance.  Upon Lender's request, Borrower will provide Lender and/or
Lender's representatives access to Borrower's books, records and properties
at such times during ordinary business hours as Lender may request.

     (b)  REIMBURSEMENT; INDEMNITY.  Borrower will reimburse Lender for all
its costs and expenses in connection with this Agreement, including, without

to indemnify and hold Lender harmless from any costs or expense incurred by
Lender as a result of the provisions of federal, state and local environmental
laws and ordinances, including without limitation the Comprehensive
Environmental Response, Compensation and Liability Act, as such laws and
ordinances may relate to Borrower or any property or operations of Borrower.

     (c)  BORROWING BASE.  The aggregate outstanding indebtedness pursuant to
the Credit Facility shall never exceed the maximum

amount determined by Lender, in its sole discretion, in accordance with its
normal customary oil and gas lending parameters and procedures (the
"Borrowing Base"). The initial  Borrowing Base shall be Seven Hundred Twenty
Thousand and No/100 Dollars ($720,000.00). The Borrowing Base shall be
reduced by $30,000.00 effective the first day of each month commencing
August 1, 1997. The amount of the Borrowing Base will be redetermined by
Lender as of each Borrowing Base Redetermination Date, taking into
consideration such matters as Lender, in its sole discretion, deems relevant.
The Borrowing Base shall be increased or decreased, as the case may be,
immediately upon each Borrowing Base Redetermination Date. As used herein,
the term "Borrowing Base Redetermination Date" shall mean each November 1 and
each May 1, commencing November 1, 1997, as well as any other date on which
Lender, in its sole discretion, redetermines the Borrowing Base. Upon any
change in the Borrowing Base, Lender shall redetermine, in its sole
discretion, the amount by which the Borrowing Base will reduce effective the
first day of each month thereafter. If the amount outstanding under the
Credit Facility at any time is greater than the Borrowing Base at such time,
Borrower shall, within thirty (30) days after written notice thereof from
Lender, make a prepayment on the Revolving Note in an amount sufficient to
reduce the outstanding amount thereof to an amount not more than the
Borrowing Base.

     (d) SECURITY. The Revolving Note and the other indebtedness hereunder
shall be secured by a first and prior lien on the oil and gas properties of
Borrower included in the determination of the Borrowing Base (collectively,
the "Mortgaged Property").

     (e) OPERATING ACCOUNTS. Borrower shall maintain with Lender all of
Borrower's operating accounts and will deposit into such accounts all
proceeds of any property forming a portion of the Borrowing Base. Borrower
hereby authorizes Lender to debit, without notice to Borrower, from any
operating or other deposit account maintained by Borrower with lender, all
sums which may become due or owing under the terms of this Agreement or the
Revolving Note, including without limitation, all payments of principal and
interest as they become due under the Revolving Note.

     (f) GUARANTEE. The Revolving Note and the other indebtedness hereunder
shall be guaranteed by Prentis B. Tomlinson, Jr. ("Tomlinson"), Benz Energy
Ltd., a Yukon Territory corporation ("Benz Energy"), Prentis B. Tomlinson,
Jr., Trustee of and on behalf of The Slattery Trust, the Ruston Trust and the

any of the other Loan Documents shall be construed to obligate Borrower,
under any circumstances whatsoever, to pay interest in excess of the maximum
non-usurious interest rate applicable to Borrower. In the event that any sums
received from Borrower are at any time under applicable law deemed to be in

rate or the application of those sums as a credit against the unpaid

privilege of Lender under this Agreement or any other Loan Document shall
operate as a waiver thereof. The rights and remedies of Lender under this
Agreement and the other Loan Documents shall be cumulative and the exercise
or partial exercise of any such right or remedy shall not preclude the
exercise of any other right or remedy.

     (g) GOVERNING LAW. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS SHALL BE
DEEMED TO BE CONTRACTS MADE UNDER AND SHALL BE CONSTRUED IN ACCORDANCE WITH
AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS.

     (h) INVALID PROVISIONS. In the event any one or more of the provisions
contained in this Agreement or any of the other Loan Documents shall, for any
reason, be held to be invalid, illegal or unenforceable in any respect, such
invalidity, illegality or unenforceability shall not affect any other
provision of this Agreement or the other Loan Documents. Furthermore, in lieu
of such invalid, illegal or unenforceable provision, there shall
automatically be added a provision as similar in terms to such invalid,
illegal or unenforceable provision as may be possible and as may be valid,
legal and enforceable.

$10,000,000.00                                                  July 17, 1997


         FOR VALUE RECEIVED, after date, without grace, in the manner, on the
dates and in the amounts so herein stipulated, the undersigned, TEXSTAR
PETROLEUM, INC., a Texas corporation ("Borrower"), PROMISES TO PAY TO THE
ORDER OF BANK ONE, TEXAS, N.A., a national banking association ("Lender"), in
Houston, Harris County, Texas, the sum of TEN MILLION AND NO/100 DOLLARS
($10,000,000.00) or, if less, the aggregate unpaid principal amount of
advances made by Lender to Borrower pursuant to this Promissory Note (this
"Note"), in lawful money of the United States of America, which shall be
legal tender in payment of all debts and dues, public and private, at the
time of payment, and to pay interest on the advanced and unpaid principal
amount from date until maturity at a rate equal to the Base Rate (hereinafter
defined) plus two percent (2%) per annum ("Stated Rate"), not to exceed the
maximum non-usurious interest rate permitted by applicable law from time to
time in effect as such law may be interpreted, amended, revised, supplemented
or enacted ("Maximum Rate"), provided that if at any time the Stated Rate
exceeds the Maximum Rate then interest hereon shall accrue at the Maximum
Rate. In the event the Stated Rate subsequently decreases to a level less
than the Maximum Rate or if the Maximum Rate applicable to this Note should
subsequently be increased to a level greater than the Stated Rate, then, in
either case, interest hereon shall thereafter accrue at a rate equal to the
applicable Maximum Rate until the aggregate amount of interest accrued
through the term of this Note equals the aggregate amount of interest which
would have accrued at the Stated Rate without regard to any usury limit, at
which time interest hereon shall again accrue at the Stated Rate.

         This Note is payable as follows:

              1.  Accrued and unpaid interest shall be due and payable on the
         first day of each month, commencing August 1, 1997.

              2.  All accrued and unpaid interest and unpaid principal shall
         be due and payable on June 30, 2000.

All payments under this Note shall be applied first against the accrued and
unpaid interest hereon and the remainder against the principal balance hereof.

         This Note is subject to mandatory prepayments, as set forth in the
Loan Agreement (hereinafter defined). In addition, Borrower may prepay this
Note, in whole or in part, at any time prior to maturity without penalty, and
interest shall cease on any amount

prepaid. Any partial prepayment shall be applied toward the payment of the
principal installments last maturing on the Note, that is, in the inverse
order of maturity, without reducing the amount or time of payment of the
remaining installments.

         Any check, draft, money order or other instrument given in payment
of all or any part hereof may be accepted by Lender and handled in collection
in a customary manner, but same shall not constitute payment hereof or
diminish any rights of Lender except to the extent that actual cash proceeds
of such instrument are unconditionally received by Lender.

         It is agreed that time is of the essence of this agreement.  In the
event of default in the payment of any installment of principal or interest
when due or in the event of any other default hereunder, Lender may
accelerate and declare this Note immediately due and payable without notice.
Any failure to exercise this option shall not constitute a waiver by Lender of
the right to exercise the same at any other time.

         In the event of default in the making of any payment herein
provided, either of principal or interest, or in the event this Note is
declared due, interest hereunder shall accrue at the Maximum Rate.

         Borrower hereby agrees to pay all expenses, including reasonable
attorneys' fees, all of which shall become a part of the principal hereof,
incurred by Lender if this Note is placed in the hands of an attorney for
collection or if collected by suit or through any probate, bankruptcy or any
other legal proceedings.

         Interest charges will be calculated on amounts advanced hereunder on
the actual number of days the amounts are outstanding on the basis of a
365-day or 366-day year, as is applicable.

         It is expressly stipulated and agreed to be the intent of Borrower
and Lender to comply with applicable Texas law governing the maximum
non-usurious rate or amount of interest payable on or in connection with this
Note (or applicable United States federal law to the extent that it permits
Lender to contract for, charge, take, reserve or receive a greater amount of
interest than under Texas law). Accordingly, it is agreed that notwithstanding
any provision to the contrary in this Note, or in any of the documents
securing payment hereof or otherwise relating hereto, no such provision shall
require the payment or permit the collection of interest at a rate in excess
of the Maximum Rate. If any excess of interest in such respect is provided
for, or shall be judicially interpreted to be so provided for, in this Note
or in any of the documents securing payment hereof or otherwise relating
hereto, or if the acceleration of the maturity of this Note or any prepayment
by Borrower results in Borrower's having paid any interest in excess of that
permitted by applicable law, then in any such event,


- --------
Initials                              -2-
<PAGE>

it is the express intent of Borrower and Lender that (1) the provisions of
this paragraph shall govern and control, (2) neither Borrower nor any other
person primarily liable on this Note, nor their respective heirs, legal
representatives, successors or assigns, shall be obligated to pay the amount
of such interest to the extent that it is in excess of the Maximum Rate,
(3) any such excess which may have been collected shall be either applied as
a credit against the then unpaid amount hereof or refunded to Borrower, and
(4) the provisions of this Note and any documents securing payment of this
Note shall be automatically deemed reformed and the amounts thereafter
collectible thereunder reduced, without the necessity of the execution of any
new document, so that the effective rate of interest shall be reduced to the
Maximum Rate. For the purpose of determining the maximum amount of interest
permitted to be charged or collected hereunder, all sums paid or agreed to be
paid to Lender for the use, forbearance or detention of the proceeds of this
Note shall be amortized, prorated, allocated and spread throughout the full
term of this Note so that the rate or amount of interest on account of this
Note is uniform throughout the term hereof and does not exceed the applicable
usury ceiling.

     Borrower agrees that the Maximum Rate to be charged or collected pursuant
to this Note shall be the indicated rate ceiling referred to in TEX. REV.
CIV. STAT. ANN. Art. 5060-1.04, provided that Lender may rely on other
applicable laws, including without limitation laws of the United States, for
calculation of the Maximum Rate if the application thereof results in a
greater Maximum Rate. Except as provided above, the provisions of this Note
shall be governed by the laws of the State of Texas.

    Borrower and each other person who is a maker, surety, guarantor or
endorser of this Note hereby waives demand, grace, notice,  presentment for
payment, notice of intention to accelerate the maturity hereof, notice of the
acceleration of the maturity hereof and protest, and agrees that this Note and
the liens securing its payment may be renewed, and the time of payment
extended, from time to time, without notice and without releasing any of the
foregoing. As additional security for all amounts owed by Borrower to Lender,
Borrower hereby grants to Lender a lien and security interest on (and the
express right of setoff against) any of Borrower's funds which may from time
to time be deposited with or in the possession of Lender.

     As used in this Note, the term "Base Rate" shall mean at any time the
variable rate of interest then most recently announced publicly by Lender (or
any successor to all or substantially all of its assets) as its base rate of
interest and, without notice to Borrower or any other person, such rate of
interest shall change as and when changes in that base rate of interest are
announced.

duties according to the terms and conditions hereof;

           NOW THEREFORE this Agreement witnesseth that in consideration of
the aforesaid agreements, and of the sum of one dollar ($1.00) now paid by
the parties hereto, each to the other (receipt of which sum the parties do
hereby respectively acknowledge each to the other) the Security Holders
jointly and severally covenant and agree with each other and with the Issuer
and the Trustee as follows:

<PAGE>


                                       -2-


1.   For the purposes of this agreement the following terms shall have the
following meanings:

     (a)   "acceptance date" means the date of the receipt issued by the
           Director of the Commission pursuant to Section 61 of the SECURITIES
           ACT (Ontario) for the final prospectus of the Issuer dated on or
           about September 16, 1997 qualifying the issuance of securities upon
           the exercise of previously issued special warrants; and

     (b)   "Commission" means the Ontario Securities Commission.

2.   Each of the Security Holders hereby places and deposits in escrow with
the Trustee those of its securities of the Issuer which are represented by
the certificates described or referred to in Schedule "A" hereto (the
"Escrowed Shares") and hereby undertakes and agrees forthwith to deliver
those  certificates (including any replacement securities or certificates if
and when such are issued or allotted) to the Trustee for deposit in escrow.

3.   The parties hereby agree that except as otherwise set out herein, the
Escrowed Shares and the beneficial ownership of or any interest in them and
the certificates representing them (including any replacement securities or
certificates) shall not be sold, assigned, hypothecated, pledges, charged,
alienated, released from escrow, transferred within escrow, or otherwise in
any manner dealt with, without the express prior consent in writing of the
Commission.  The foregoing shall not prevent any transfer or assignment which
may be required by reason of the death or bankruptcy of any Security Holder,
in which case the Trustee shall hold the said securities and certificates in
escrow subject to provisions of this agreement, for whatever person or
company shall be legally entitled to be or become the registered owner
thereof.  Notwithstanding the foregoing, in circumstances where one or more
persons or companies, each being at arm's length (as such term is defined in
the Income Tax Act (Canada)) to the Security Holder, (the "Offeror") makes
either (i) a bona fide take-over bid by way of circular (as contemplated by
the Ontario or British Columbia Securities Acts) or (ii) a bona fide take-over
bid (as contemplated under the rules of The Toronto Stock Exchange or the
Vancouver Stock Exchange) through the facilities of The Toronto Stock
Exchange or Vancouver Stock Exchange, to acquire all the common shares of the
Issuer and to all holders of common shares of the Issuer on the same terms,
the Trustee may, upon receiving written direction from the Security Holder,
tender to any such take-over bid the share certificates representing the
number of Escrowed Shares the Security Holder desires to have deposited under
such take-over bid (the "Deposited Escrowed Shares") provided that the
Trustee receives from the Offeror either before or concurrently with the
tendering of the Deposited Escrowed Shares a certificate of an authorized
signing officer of the Offeror to the effect that the terms and conditions of
the take-over bid have been met or satisfied and that the Offeror is
irrevocably obligated to, and will, take up and pay for all securities
deposited under the take-over bid; however, for greater certainty, the
Trustee shall take appropriate steps to ensure that if all the terms and
conditions of the take-over bid are not met or satisfied or all the
securities duly deposited thereunder are not taken up and paid for, the
Deposited Escrowed Shares shall not be taken up or paid for and shall remain in
escrow subject to the terms and provisions of this Agreement.

4.   It is agreed that the Escrowed Shares will be released from escrow from
time to time in accordance with the provisions of Article six of Ontario
Securities Commission Policy 5.2 ("Policy 5.2"), with the following
additional qualifications:

     (a)   all automatic share releases (ie releases based upon expiry of
           time) pursuant to Section 6.5 of Policy 5.2 will be made in
           accordance with Schedule "B" hereto.  The consent of the
           Commission is not required for automatic releases in accordance
           with Schedule "B" hereto and the Trustee is hereby authorized to
           release the certificates representing the Escrowed Shares to the
           Security Holders in the amounts and at the times set out in
           Schedule "B" hereto; and

     (b)   all earned share releases pursuant to Sections 6.6 and 6.7 of
           Policy 5.2 will be made to the Security Holders other than Boone
           Petroleum Inc. and C'est La Vie Enterprises, pro rata in
           accordance with the number of securities deposited in escrow as
           shown on Schedule "A" hereto.

5.   The Security Holders hereby direct the Trustee to retain their
respective securities and the certificates (including any replacement
securities or certificates) representing the same and not to do or cause
anything to be done to release the same from escrow or to allow any sale,
assignment, hypothecation, pledge, charge or alienation


<PAGE>


                                     - 3 -


thereof except with the prior written consent of the Commission. The Trustee
accepts the responsibilities placed on it hereby and agrees to perform the
same in accordance with the terms hereof.

6.    If during the period in which any of the said securities are retained
in escrow pursuant hereto, any cash dividend is received by the Trustee in
respect of the escrowed securities, any such cash dividend shall be forthwith
paid or transferred to the respective Security Holders entitled thereto. If
during the period in which any of the said securities are retained in escrow
pursuant hereto, any share dividend or other distribution of securities is
received by the Trustee in respect of the escrowed securities, subject to
Policy 5.2, any certificates representing such share dividend or securities
must be held by the Trustee on and subject to the terms of this agreement. If
during the period in which any of the said securities are retained in escrow
pursuant hereto, any share dividend or other distribution of securities is
received by a Security Holder in respect of the escrowed securities, any
certificates representing such share dividend or securities must be forthwith
deposited with the Trustee to be held by the Trustee on and subject to the
terms of this agreement.

7.    All voting rights attached to the escrowed securities shall at all
times be exercised by the respective registered owners thereof and the
Trustee shall take all necessary steps from time to time to permit the
registered holders to exercise such rights.

8.    The Security Holders hereby agree that any escrowed securities of the
Issuer remaining in escrow on the day which is the tenth anniversary of the
acceptance date, shall be donated to and cancelled by the Issuer without
payment by the Issuer of any consideration therefor. In order to effect such
donation and cancellation, the Security Holders do hereby nominate,
constitute and appoint the president of the Issuer from time to time as their
true and lawful attorney with full power of substitution to execute in the
name of and on behalf of the Security Holders such deeds, documents and other
instruments as may be necessary or desirable to give full force and effect to
the provisions of this agreement insofar as it relates to the cancellation of
escrowed securities as aforesaid. This power of attorney shall be coupled
with an interest and shall survive the death or incapacity of the Security
Holders. Where an application is made by the Issuer or the Security Holders
to the Commission for an extension of the time by which the escrowed
securities are subject to donation and cancellation then this power of
attorney shall be suspended while such application is being processed but
shall be immediately reinstated for use upon a decision being rendered by the
Commission in respect of such application and only in accordance with the
decision of the Commission.

9.    The Security Holders and the Issuer hereby jointly and severally agree
to and do hereby release and indemnify and save harmless the Trustee from and
against all claims, suits, demands, costs, damages and expenses which may be
occasioned by reason of the Trustee's compliance in good faith with the terms
hereof.

10.   The Issuer hereby acknowledges the terms and conditions of this
agreement and agrees to take all reasonable steps to facilitate its
performance.

11.   If the Trustee should wish to resign, it shall give at least six months
notice to the Issuer and the Commission whereupon the Issuer may, with the
written consent of the Commission, by writing appoint another Trustee in its
place and such appointment shall be binding on the Security Holders and the
new Trustee shall assume and be bound by the obligations of the Trustee
hereunder.

12.   The written consent of the Commission to a release from escrow of all
or any part of the escrowed securities shall terminate this agreement only in
respect of those securities so released. For greater certainty, this clause
does not apply to securities transferred within escrow.

13.   Any Security Holder may hypothecate, pledge or charge any or all
securities owned by it and deposited in escrow hereunder to a financial
institution, provided that prior to such hypothecation, pledge or charge,
such financial institution enters into an agreement with the Trustee and the
Issuer whereby it agrees to be bound by the provisions of this agreement and
acknowledges that the securities so hypothecated, pledged or charged may
not be sold, transferred or otherwise dealt with except in accordance with
the provisions of this agreement.

14.   This agreement may be executed in several parts in the same form and
such parts as so executed shall together form one original agreement, and
such parts if more than one shall be read together and construed as if all
the signing parties hereto had executed one copy of this agreement.

the rights of the parties shall be governed by, the laws of the Province of
Ontario. Each of the parties hereto irrevocably attorns to the jurisdiction
of the courts of the Province of Ontario.

17.   This agreement shall enure to the benefit of and be binding upon the
parties hereto, their and each of their heirs, executors, administrators,
successors and assigns.

                           VOLUNTARY POOLING AGREEMENT


THIS AGREEMENT DATED FOR REFERENCE THE 18th DAY OF APRIL, 1997.

BETWEEN:

          BENZ EQUITIES LTD., a Yukon company having an office at
          1305-1090 West Georgia Street;

          (the "Issuer")

AND:

          C.M. OLIVER & COMPANY LIMITED 2nd Floor, 750 West
          Georgia Street, Vancouver, B.C.;

          (the "Agent")

AND:

          THE UNDERSIGNED SECURITYHOLDERS of BENZ EQUITIES LTD.,

          (the "Pooled Securityholders")

AND.


          MONTREAL TRUST COMPANY OF CANADA, having an office at
          510 Burrard Street, Vancouver, British Colombia, V6C 3B9;

          (the "Trustee")

WHEREAS the Pooled Securityholders are the legal and beneficial owners of
certain common shares of the Issuer presently owned by them or to be acquired by
them upon exercise of special warrants, and are desirous of placing in a pool
the number of shares set opposite their names in Schedule "A" hereto attached
(the "Shares"), upon and subject to the terms and conditions hereinafter more
particularly set out;

NOW THEREFORE THIS AGREEMENT WITNESSES that in consideration of the premises and
in consideration of the sum of Ten Dollars ($10) now paid by the parties hereto,
each to the other, the receipt and sufficiency of which is hereby acknowledged,
and in further consideration of the mutual covenants and conditions hereinafter
contained, the parties hereto agree (the "Agreement") as follows:

1.  In this Agreement:

    (a)  "Agency Agreement" means the agreement dated March 5, 1997 whereby the
         Issuer appointed C.M. Oliver & Company Limited as its agent to offer
         1,910,000 special warrants;


<PAGE>

    (b)  "Closing Date" means the date of the final closing of the private
         placement of special warrants offered pursuant to the Agency Agreement;

    (c)  "Market Price" means at any date the weighted average price at which
         the Issuer's common shares have traded during 20 trading days at a
         daily volume of not less than 50,000 shares during a period of 30
         consecutive trading days ending on the fifth trading day before such
         date, on the Vancouver Stock Exchange, or if the Issuer's common
         shares are listed on the Toronto Stock Exchange, then on the Toronto
         Stock-Exchange. The weighted average price per share shall be
         determined by dividing the aggregate sale price of all such shares
         sold on the applicable exchange during the 20 trading days by the
         total number of shares sold; and

    (d)  "Offering Price" means the price at which the special warrants of the
         Issuer are sold pursuant to the Agency Agreement-,

2.  The Pooled Securityholders hereby severally agree each with the other and
with the Trustee that they will respectively deliver or cause to be delivered
to the Trustee certificates for their securities of the Issuer as set out in
the said Schedule "A" to be held by the Trustee and released pro rata to the
Pooled Securityholders, subject to paragraphs 3 and 5, on the basis set forth
in Schedule "B".

3. With respect to those securities pooled hereunder which are convertible or
exercisable for shares of the Company (the "Convertible Securities"), the
Trustee is hereby authorized to release from pool any of such Convertible
Securities against delivery, for deposit hereunder, of the common shares of
the Company issued upon the conversion or exercise of the released
Convertible Securities.

4. Prentis B. Tomlinson, Jr. ("Tomlinson") confirms that 2,400,000 of the
shares and of the warrants which are being deposited hereunder by Boone
Petroleum Inc. ("Boone") and DNG Capital Corp. ("DNG") are subject to option
to Tomlinson until October 31, 1998 and will remain in pool after exercise of
all or any portion of such option by him until release on the basis of the
schedule set forth in Schedule "B". In the event of exercise of all or a
portion of the option by Tomlinson, written notice of such exercise will be
delivered to the Trustee by Boone, DNG and Tomlinson together with an amended
Schedule "B".

5. If at any time prior to three years after the Closing Date, the Market
Price of the Issuer's Shares equals at least twice the Offering Price (a
"Triggering Event"), the release schedule in paragraph 2 will be accelerated
by one year. After the first acceleration of the release schedule, a
Triggering Event for any further one year accelerations will be the Market
Price equalling at least twice the Market Price on which the previous
acceleration was based. The Trustee will be provided with written
notification from the Company and the Agent of any Triggering Event.

6. Each of the Pooled Securityholders are entitled to a letter or receipt from
the Trustee stating the number of Shares represented by certificates held for
him by the Trustee subject to the terms of this Agreement, but such letter or
receipt shall not be assignable.

7. Except with the written consent of the Agent and the Company:

   (a)  the Pooled Securityholders will not sell, deal in, assign, or
        transfer in any manner whatsoever or agree to sell, deal in, assign
        or transfer in any manner whatsoever any of the Shares or beneficial
        ownership of or any interest in them; and


                                      -2-

   (b)   the Trustee shall not accept or acknowledge any transfer, assignment,
         declaration of trust or any other document evidencing a change in
         legal and beneficial ownership or of interest in the Shares, except
         as may be required by reason of the death or bankruptcy of any one or
         more of the Pooled Securityholders, subject to this Agreement for
         whatever person or persons, firm or corporation may thus become
         legally entitled thereto.

8. This Agreement shall enure to the benefit of and be binding upon the parties
hereto and each of their heirs, executors, administrators, successors and
permitted assigns.

9. This Agreement may be executed in several parts in the same form and such
part as so executed shall together constitute one original agreement, and such
parts, if more than one, shall be read together and construed as if all the
signing parties hereto had executed one copy of this Agreement.

10. The parties hereto agree that in consideration of the Trustee agreeing to
act as Trustee as aforesaid, the Pooled Securityholders do hereby covenant and
agree from time to time and at all times hereinafter well and truly to save,
defend, and keep harmless and fully indemnify the Trustee, its successors and
assigns, from and against all loss, costs, charges, damages and expenses which
the Trustee, its successors or assigns, may at any time or times hereafter bear,
sustain. suffer or be put to for or by reason or on account of its acting as
Trustee pursuant to this Agreement.

11. It is further agreed by and between the parties hereto and, without
restricting the foregoing indemnity, that in case proceedings should hereafter
be taken in any Court respecting the shares hereby pooled, the Trustee shall not
be obliged to defend any such action or submit its rights to the Court until it
shall have been indemnified by other good and sufficient security in addition to
the indemnity hereinbefore given against costs of such proceedings.

12. It is further agreed by and between the parties hereto that this Agreement
shall be construed in accordance with the laws of the Province of British
Columbia. The parties hereby attorn to the jurisdiction of the courts of
competent jurisdiction of the Province of British Columbia.

presents as from the day and year first above written.

provided herein (or such other address as may be designated by Landlord in
writing from time to time) monthly, in advance, and without demand. If the
Lease Term commences on a day other than the first day of a month or
terminates on a day other than the last day of a month, then (i) the
installments of Base Rental for such month or months shall be prorated, based
on the number of days in such month, and (ii) Tenant's share of Basic Costs
shall be prorated as specified in EXHIBIT "C" hereto.

          (b)   All installments of Rent not paid when due and payable shall
bear interest at the maximum lawful rate until paid.

          (c)   The Base Rental payable hereunder shall be adjusted from time
to time in accordance with the provisions of EXHIBIT "C" attached hereto and
incorporated herein for all purposes.

     6.  SERVICES TO BE FURNISHED BY LANDLORD.  Landlord agrees to furnish

air conditioning in season, at such temperatures and in such amounts as are
reasonably considered by Landlord to be standard or as required by
governmental authority; provided, however, heating and air conditioning
service at times other than for Normal Business Hours for the Building shall
be furnished only upon the request of Tenant delivered to Landlord at any
time pursuant to the Building's computerized system for such purposes. Tenant
shall bear the entire cost of additional service, as such costs are
determined by Landlord from time to time, and shall pay the same as
additional Rent upon presentation of a statement therefor by Landlord. The
additional air conditioning or chilled water consumption shall be determined
as measured by BTU meters and submeters installed and maintained in good
order and repair at Tenant's expense.

          (b)   Routine maintenance and electric lighting service for all
Common Areas and Service Areas of the Building in the manner and to the
extent deemed by Landlord to be standard.

          (c)   Janitor service, five (5) days per week, exclusive of normal
business holidays; provided, however, if Tenant's floor covering or other
improvements require special treatment, Tenant shall pay the additional
cleaning cost attributable thereto as additional Rent upon presentation of a
statement therefor by Landlord.

          (d)   Subject to the provisions of Paragraph 12, facilities to
provide all electrical current required by Tenant in its use and occupancy of
the Premises.

          (e)   All Building Grade fluorescent bulb replacements in the
Premises necessary to maintain the lighting provided as a part of the Shell
Improvements and fluorescent and incandescent bulb replacement in the Common
Areas and Service Areas.

          (f)   Landlord shall provide limited access to the Building before
and after Normal Business Hours in the form of special limited access entry
cards ("Entry Cards") for Tenant and its employees. An Entry Card shall not
automatically qualify Tenant or any of its employees for an access card to
the "Parking Garage" as defined in and pursuant to the terms of EXHIBIT "F".
Landlord agrees to provide Tenant with up to, but not in excess of, six (6)
Entry Cards. However, Tenant shall pay Landlord for any additional or
replacement cards, in such amount as Landlord shall, from time to time,
determine. The current cost required for a replacement card is $10.00 per
card. Landlord shall be entitled to cancel (by computer entry) any lost or
stolen cards of which it becomes aware. Tenant shall promptly notify Landlord
of any lost or stolen cards. Landlord shall have no liability to Tenant, its
employees, agents, invitees, or licensees for losses due to theft or
burglary, or for damages committed by unauthorized persons on the Premises;
and neither shall Landlord be required to insure

OFFICE LEASE AGREEMENT - Page 2

<PAGE>

against any such losses. Tenant shall cooperate fully in Landlord's efforts to
maintain security in the Building and shall follow all regulations
promulgated by Landlord with respect thereto. Tenant further agrees to
surrender all Entry Cards in its possession upon the expiration or earlier
termination of this Lease.

          No interruption or malfunction of any utility service shall
constitute an eviction or disturbance of Tenant's use or possession of the
Premises or a breach by Landlord of any of Landlord's obligations hereunder
or render Landlord liable or responsible to Tenant for any loss or damage
which Tenant may sustain or incur if either the quantity or character of any
utility service is changed or is no longer available to or is no longer
suitable for Tenant's requirements or entitle Tenant to be relieved from any
of Tenant's obligations hereunder, including, without limitation, the
obligation to pay Rent, or grant Tenant any right to set-off, abatement or
recoupment. At any time when Landlord is making such facilities for such
utility services available to the Premises, Landlord may, at Landlord's
option, upon not less than thirty (30) days prior written notice to Tenant,
discontinue the availability of any such utility service. If Landlord gives
any such notice of discontinuance, Landlord shall make all the necessary
arrangements with the public utility service supplying the utility to the
area in which the Building is located with respect to obtaining such utility
service to the Premises; but Tenant will contract directly with such public
utility service for the supplying of such utility services to the Premises.
Failure to any extent to make available, or any slowdown, stoppage, or
interruption of, the specified utility services resulting from any cause,
including, without limitation, Landlord's compliance with any voluntary or
similar governmental or business guidelines now or hereafter published or any
requirements now or hereafter established by any governmental agency, board,
or bureau having jurisdiction over the operation of the Building shall not
render Landlord liable in any respect for damages to either persons,
property, or business, nor be construed as an eviction of Tenant or work an
abatement of Rent, nor relieve Tenant of Tenant's obligations for fulfillment
of any covenant or agreement hereof. Should any equipment or machinery
furnished by Landlord breakdown or for any cause cease to function properly,
Landlord shall use reasonable diligence to repair same promptly, but Tenant
shall have no claim for abatement of Rent or damages on account of any
interruption of service occasioned thereby or resulting therefrom.

     7.   IMPROVEMENTS TO BE MADE BY LANDLORD.  Except as otherwise provided
in the Work Letter attached hereto as EXHIBIT "E", all installations and
improvements now or hereafter placed on the Premises, other than shell
improvements, shall be for Tenant's account and at Tenant's cost (and
Tenant shall pay ad valorem taxes and increased insurance thereon or
attributable thereto), which cost shall be payable by Tenant to Landlord upon
demand as additional Rent.

     8.   MAINTENANCE AND REPAIR OF PREMISES BY LANDLORD.  Except as
otherwise expressly provided herein, Landlord shall not be required to make
any repairs to the Premises other than repairs to exterior and load-bearing
walls, floors (but not floor coverings) and the roof of the Building, which
may be required from time to time but only after such required repairs have
been requested by Tenant in writing. In no event shall Landlord be
responsible for the maintenance or repair of Improvements which are not
composed of Building Grade materials.

     9.   GRAPHICS.  Landlord shall provide and install, at Tenant's cost,
all letters or numerals on doors in the Premises, identification graphics on
the exterior of the Premises, and all signage related to Tenant's occupancy
in the Building. All such letters and numerals shall be in the standard
graphics for the Building and no others shall be used or permitted on the
Premises without Landlord's prior written consent.

     10.  CARE OF THE PREMISES BY TENANT.  Tenant shall, at its own cost and
expense, reasonably maintain and repair the Premises, and shall not commit or
allow any waste to be committed on any portion of the Premises, and at the
termination of this Lease to deliver up the Premises to Landlord in as good
condition as at the date of the commencement of the term of this Lease,
ordinary wear and tear excepted.

     11.  REPAIRS AND ALTERATIONS BY TENANT.  Landlord shall have the right,
at its option, at Tenant's own cost and expense, to repair or replace any
damage done to the Building, or any part thereof, caused by tenant or
Tenant's agents, employees, invitees, or visitors, and Tenant shall pay the
cost thereof to the Landlord on demand as additional Rent. Tenant agrees with
Landlord not to make or allow to be made any alterations to the Premises,
install any vending machines on the Premises, or place signs on the Premises
which are visible from outside the Premises, without first obtaining the
prior written consent of Landlord in each such instance, which consent may be
given or withheld on such conditions as Landlord may elect. Any and all
alterations to the Premises shall become the property of Landlord upon
termination of this Lease (except for movable equipment or furniture owned by
Tenant). Landlord may, nonetheless, require Tenant to remove any and all
fixtures, equipment and other improvements installed on the Premises or the
Building ("Additional Improvements") beyond the shell improvements. Tenant
shall be responsible for repairing any damage to the Premises or the Building
resulting from the removal of any Additional Improvements or Tenant's personal
property and for restoring the Premises or the Building, as applicable, to
Building Grade condition. In the event that Landlord so elects, and Tenant
fails to remove the Additional Improvements, Landlord may remove the
Additional Improvements at Tenant's cost, and Tenant shall pay Landlord on
demand all costs incurred in removing the Additional Improvements.

     12.  USE OF ELECTRICAL SERVICES BY TENANT.  Proper facilities so as to
enable appropriate utility company to furnish electrical facilities for a
total connected load of 2.0 watts per square foot of Rentable Area of power
for high voltage (277/480v) electrical requirements ("Tenant's High Voltage
Power Load") and 3.0 watts per square foot of Rentable Area for low voltage
(120/208v single phase) electrical requirements ("Tenant's Low Voltage Power
Load") (Tenant's Low Voltage Power Load and Tenant's High Voltage Power Load
collectively shall mean "Tenant Standard Electrical Power"). All Tenant
Standard Electrical Power shall be supplied by Landlord and paid for by
Tenant as a part of its proportionate share of Building Operating Costs (as
hereinafter defined in Paragraph 13, of this Lease); provided, however, any
Low Voltage Power consumed in the Premises in excess of .34 kilowatt hours
per square foot of Rentable Area within the Premises per month and any
electricity for any item that requires a voltage other than 120/208v single
phase will be considered to be in excess of Tenant's Low Voltage Power Load
and will be separately metered and billed to Tenant on a monthly basis.
Notwithstanding the above, high voltage power used for Building standard
lighting will not be metered unless the Building standard allowance for
lighting (defined as one (1) 2x2 parabolic lighting fixture for each eighty
(80) square feet of Rentable Area within the Premises) is exceeded.

     In the event Tenant's requirements for a connected load exceed those set
forth in the preceding paragraph, Landlord, at Tenant's sole expense, will
make reasonable efforts to supply such additional service through the existing
electrical system serving the Building. Any additional electrical equipment
required to meet Tenant's excess electrical requirements will be installed by
Landlord at the sole cost and expense of Tenant (if, in Landlord's sole
judgment, the same are necessary and will not cause damage or injury to the
Building or the Premises or cause or create a dangerous or hazardous
condition or entail excessive or unreasonable alterations, repairs or expense
or unreasonably interfere with or disturb other tenants or occupants).


OFFICE LEASE AGREEMENT - Page 3
<PAGE>

     In the event Tenant's Premises is not initially metered as set forth
above, any 277/480v or 120/208v lighting or equipment requirements installed
at a later date or any other special situations that create a demand for
additional electrical usage exceeding the Tenant Standard Electrical Power
will be metered and/or measured by Landlord's engineers and billed to Tenant
on a monthly basis. All installations of non-standard electrical fixtures
such as appliances and equipment (other than ordinary office appliances and
equipment such as typewriters, personal computers, word processors,
voicewriters, calculators, lamps, clocks and other similar type low
electrical consumption appliances and equipment) within the Premises will be
subject to prior notice to Landlord, and, in the event any such installation
will, either directly or indirectly, adversely affect the base electrical or
mechanical systems, Landlord's prior approval will be required. Tenant
covenants and agrees that at all times its use of electrical current will
never intentionally exceed the capacity of existing feeders to the Building
or the risers or wiring installations.

     Landlord will not be liable in any way to Tenant for any failure or
defect in the supply or character of electrical energy furnished to the
Premises by reason of any requirement, act or omission of the public utility
serving the Building with electricity. The obligations of Landlord to furnish
electrical service will be subject to the rules and regulations of the
supplier of such electricity and of any municipal or other governmental
authority regulating the business of providing electrical utility service.

     13.  LAWS AND REGULATIONS. Tenant agrees to comply with all applicable
laws, ordinances, rules, and regulations of any government entity or agency
having jurisdiction with respect to the Premises.

     14.  BUILDING RULES. Tenant will comply with the rules and regulations of
the Building as adopted and altered by Landlord from time to time and will
cause all of its agents, employees, invitees and visitors to do so. All
changes to such rules will be sent by Landlord to Tenant in writing. The
current rules and regulations for the Building are attached hereto as EXHIBIT
"D".

     15.  ENTRY BY LANDLORD. Tenant agrees to permit Landlord or its
employees, agents or representatives to enter into and upon any part of the
Premises at all reasonable hours (and in emergencies at all times) to inspect
the same, or to show the Premises to prospective purchasers, mortgagees,
tenants or insurers, to clean or make repairs, alterations or additions
thereto, and Tenant shall not be entitled to any abatement or reduction of
Rent by reason thereof.

     16.  ASSIGNMENT AND SUBLETTING.

          (a)   Tenant shall not (i) assign this Lease or any interest
therein, or (ii) sublease the Premises or any portion thereof without the
prior written consent of Landlord, which consent shall not be unreasonably
withheld. Any attempted assignment or sublease by Tenant in violation of the
terms and covenants of this paragraph shall be void. If Tenant is not a
natural person, the acquisition of a controlling interest in Tenant shall be
deemed to be an assignment for purposes hereof. As used herein, the phrase
"controlling interest" shall mean ownership of in excess of forty-nine
percent (49%) of the voting interest in Tenant. Notwithstanding the
foregoing, Tenant may, upon notice to Landlord but without the necessity of
obtaining Landlord's prior consent thereto, assign this Lease or sublet the
Premises to an "Affiliate." As used herein, the term "Affiliate" shall mean
any entity under the common control of a person or entity which controls
Tenant or which is controlled by Tenant. With respect to a request for
Landlord's consent to any assignment or sublease the following reasons for
denial shall, without limitation, be deemed to be reasonable:

               i)     the proposed assignee or subtenant does not have adequate
     financial ability to fulfill the monetary obligations related to such
     space; or

               ii)    the proposed assignee or subtenant is a tenant in the
     Building or a prospective tenant in the Building (a prospective tenant
     shall be any entity which has directly or indirectly contacted Landlord
     about space in the Building; or

               iii)   the space to be sublet is less than 2,000 square feet
     of Rentable Area; or

               iv)    if prior subleases have been consented to by Landlord,
     such proposed sublease space is not contiguous to all space on a single
     floor under such prior subleases; or

               v)     any proposed assignment appears to be an assignment of
     less than the entire Lease or less than Tenant's entire interest herein;
     or

               vi)    any proposed assignee or subtenant whose use of the
     Premises in Landlord's opinion might violate the Use clause of the
     Lease; or

               vii)   the proposed assignee or subtenant is either a
governmental agency, a school or similar operation or a medical-related
practice; or

               viii)  in Landlord's judgment, the proposed assignee or
     subtenant would diminish the value or reputation of the Building; or

               ix)    the occupancy of the Premises by the proposed subtenant
     or assignee would require substantial alterations to the Premises or the
     applicable portion thereof; or

               x)     the proposed subtenant's or assignee's use of the
     Premises would conflict with any other Building tenants' exclusive
     rights; or

               xi)    the occupancy of the Premises by the proposed subtenant
     or assignee would cause Landlord's fire and extended coverage insurance
     to be canceled or the rate therefor to be increased; or

               xii)   an event of default at such time exists; or

               xiii)  the proposed assignment or sublease is for any period
     other than any period during the Initial Term hereof.

          (b)   If Tenant requests Landlord's consent to an assignment of
the Lease or subletting of all or part of the Premises, Landlord shall either
(i) approve such sublease or assignment (but no approval of an assignment or
sublease shall relieve Tenant of any liability hereunder), or (ii) negotiate
directly with the proposed subtenant or assignee and (in the event Landlord is
able to reach agreement with such proposed subtenant or assignee) upon
execution of a lease with such proposed subtenant or assignee, terminate this
Lease (in part or in whole, as appropriate) upon thirty (30) days' notice, or
(iii) if Landlord shall fail to notify Tenant in writing of its decision
within a thirty (30) day period after Landlord is notified in writing of the


OFFICE LEASE AGREEMENT - Page 4

<PAGE>

proposed assignment or sublease, Landlord shall be deemed to have refused to
consent to such assignment or subleasing, and to have elected to keep this
Lease in full force and effect.

         (c)   All cash or other proceeds of any assignment, sale or sublease
of Tenant's interest in the Lease and/or the Premises, whether consented to
by Landlord or not, shall be paid to Landlord notwithstanding the fact that
such proceeds exceed the Base Rental called for hereunder, unless Landlord
agrees to the contrary in writing, and Tenant hereby assigns all rights it
might have or ever acquire in any such proceeds to Landlord. This covenant
and assignment shall benefit Landlord and its successors in ownership of the
Building and shall bind Tenant and Tenant's heirs, executors, administrators,
personal representatives, successors and assigns. Any assignee, sublessee or
purchaser of Tenant's interest in this Lease (all such assignees, sublessees
or purchasers being hereinafter referred to as "Successors"), by occupying
the Premises and/or assuming Tenant's obligations hereunder, shall be deemed
to have assumed liability to Landlord for all amounts paid to persons other
than Landlord by such Successor in consideration of any such sale, assignment
or subletting, in violation of the provision hereof. No assignment or
subletting, whether or not with Landlord's consent, shall ever relieve Tenant
of any liability hereunder.

    17.  MECHANIC'S LIENS. Tenant will not permit any mechanic's liens or
other liens to be placed upon the Premises or the Building and nothing in
this Lease shall be deemed or construed in any way as constituting the
consent or request of Landlord, express or implied, by inference or
otherwise, to any person for the performance of any labor or the furnishing
of any materials to the Premises, or any part thereof, nor as giving Tenant
any right, power, or authority to contract for or permit the rendering of any
services or the furnishing of any materials that would give rise to any
mechanic's or other liens against the Premises. In the event any such lien is
attached to the Premises, then, in addition to any other right or remedy of
Landlord, Landlord may, but shall not be obligated to, discharge the same.
Any amount paid by Landlord for any of the aforesaid purposes shall be paid
by Tenant to Landlord on demand as additional Rent.

    18.  PROPERTY INSURANCE. In the event that Landlord has placed or
hereafter places a mortgage, deed of trust or other lien on the Building,
then during the existence thereof, Landlord shall maintain such fire and
extended coverage insurance on the Building and the Premises as Landlord's
mortgagees shall require thereunder, and in all other instances Landlord
shall maintain such fire and extended coverage insurance on the Building and
the Premises as Landlord desires in its sole discretion. Such insurance shall
be maintained at the expense of Landlord (as a part of the Basic Costs), and
payments for losses thereunder shall be made solely to Landlord or the
mortgagees of Landlord as their interests shall appear. Tenant shall maintain
at its expense, in an amount equal to full replacement cost, fire and
extended coverage insurance on all of its personal property, including
removable trade fixtures, located on the Premises and in such additional
amounts as are required to meet Tenant's obligations pursuant to Paragraph 22
hereof. Tenant shall, at Landlord's request from time to time, provide
Landlord with a current certificate of insurance evidencing Tenant's
compliance with this Paragraph 18 and Paragraphs 19 and 21 hereof. Tenant
shall obtain the agreement of Tenant's insurers to notify Landlord that a
policy is due to expire at least thirty (30) days prior to such expiration.

    19.  LIABILITY INSURANCE. Tenant and Landlord shall (Landlord as a part
of Basic Costs and Tenant at its own expense) maintain a policy or policies
of comprehensive general liability insurance with respect to the respective
activities of each in the Building and on the Property, with the premiums
thereon fully paid on or before the due date, issued by and binding upon an
insurance company approved by Landlord, such insurance to afford minimum
protection of not less than $1,000,000 combined single limit coverage of
bodily injury, property damage or combination thereof. In addition, Tenant
agrees to obtain a fire legal liability endorsement, or other coverage
satisfactory to Landlord which removes the "leased or occupied" property
exclusion from Tenant's liability policy. Landlord shall not be required to
maintain insurance against thefts within the Premises or the Building or the
Property. Tenant's insurance shall contain a provision naming Landlord as an
additional insured and include coverage for the contractual liability of
Tenant to indemnify Landlord pursuant to Paragraph 20 below. Tenant shall
obtain the agreement of Tenant's insurers to notify Landlord that a policy is
due to expire at least thirty (30) days prior to such expiration.

    20.  INDEMNITY. Landlord shall not be liable to Tenant, or to Tenant's
agents, servants, employees, customers, or invitees for any injury to person
or damage to property caused by any act, omission, or neglect of Tenant, its
agents, servants, employees, invitees, licensees or any other person entering
the Building under the invitation of Tenant or arising out of the use of the
Premises by Tenant and the conduct of its business or out of a default by
Tenant in the performance of its obligations hereunder. Tenant hereby
indemnifies and holds Landlord harmless from all liability and claims for any
such damage or injury.

    21.  WAIVER OF SUBROGATION RIGHTS. Subject to the conditions hereinafter
specified in this Paragraph 21 and only to the extent that and so long as the
same is permitted under the laws and regulations governing the writing of
insurance within the State of Texas with respect to the respective insurance
that is to be carried by either Landlord or Tenant covering losses arising
out of the destruction or damage to the Premises or its contents or to other
portions of the Building or to Tenant's occupancy and operation of the
Premises without invalidating or nullifying any such policy, or providing a
defense to the applicable insurance carrier with respect to the coverage of
any such policy, all such insurance carried by either Landlord or Tenant
shall provide for a waiver of rights of subrogation against Landlord and
Tenant on the part of the insurance carrier. Notwithstanding the foregoing,
nothing contained herein shall require either party to obtain the inclusion
of such a waiver of rights of subrogation in the event that, because of the
cost or premium attributable to such waiver, the obtaining of such waiver is
not feasible and reasonable. Unless such waivers contemplated by this
sentence will invalidate, nullify, or provide a defense to coverage under any
such insurance policy or are not obtainable for the reasons described in this
paragraph 21, Landlord and Tenant each hereby waive any and all rights of
recovery, claims, actions or causes of action against the other, its agents,
officers, or employees, for any loss or damage that may occur to the Premises
or the Building, or any improvements thereto, which loss or damage is covered
by valid and collectible insurance policies, to the extent that such loss and
damage is actually recovered under such insurance policy. The waivers set
forth in the immediately preceding sentence shall be in addition to, and not
substitution for, any other waivers, indemnities, or exclusions of
liabilities as set forth in this Lease. Notwithstanding the foregoing, the
failure of Tenant to take out or maintain any insurance policy required under
paragraph 18 hereof shall be a defense to any claim asserted by Tenant
against Landlord by reason of any loss sustained by Tenant that would have
been covered by any such required policy.

    22.  CASUALTY DAMAGE. If the Premises or any part thereof shall be
damaged by fire or other casualty, Tenant shall give prompt written notice
thereof to Landlord. In case the Building shall be damaged such that
substantial alteration or reconstruction of the Building shell, in Landlord's
sole opinion, is required (whether or not the Premises shall have been
damaged by such casualty) or in the event any mortgagee of Landlord's should
require that the insurance proceeds payable as a result of a casualty be
applied to the payment of the mortgage debt or in the event of any material
uninsured loss to the Building, Landlord may, at its option, terminate this
Lease by notifying Tenant in writing of such termination within ninety (90)
days after the date of such casualty. If Landlord does not thus elect to
terminate this Lease, Landlord shall


OFFICE LEASE AGREEMENT - Page 5

<PAGE>

commence and proceed with reasonable diligence to restore the Building shell
and Shell Improvements located on the Premises; except that Landlord's
obligation to restore shall not require Landlord to spend for such work an
amount in excess of the insurance proceeds actually received by Landlord as a
result of the casualty. When the repairs described in the preceding sentence
have been completed by Landlord, Landlord shall then complete the restoration
of all improvements in excess of the Shell Improvements which are necessary
to permit Tenant's reoccupancy of the Premises (including the installation of
acoustical ceiling tile) pursuant to the final working drawings and
specifications approved by Landlord pursuant to the Work Letter ("Improvements
Restoration"). Landlord shall not be obligated to expend for the completion
of the Improvements Restoration a sum in excess of a dollar amount equal to
the dollar amount, if any, of the "Allowance" ("Reconstruction Allowance").
Except for the Reconstruction Allowance, all cost and expense of completing
the Improvements Restoration shall be borne by Tenant and the amount of such
excess, as determined by Landlord, is herein referred to as the
"Reconstruction Excess". Fifty percent (50%) of the Reconstruction Excess (as
then estimated by Landlord) shall be paid by Tenant to Landlord, in cash,
prior to commencement of the Improvements Restoration. After substantial
completion of the Improvements Restoration, but prior to reoccupancy of the
Premises by Tenant, Tenant shall pay Landlord, in cash, an amount equal to
ninety percent (90%) of the then unpaid balance of the Reconstruction Excess
(as then estimated by Landlord). As soon as a final accounting can be
prepared and submitted to Tenant, Tenant shall pay Landlord, in cash, the
entire unpaid balance of the Reconstruction Excess, based on Landlord's final
cost. Each increment of the Reconstruction Excess payable by Tenant to
Landlord shall be paid by Tenant within ten (10) days after a written request
therefore by Landlord to Tenant. Tenant shall not be entitled to receive any
credit or payment with respect to any portion of the Reconstruction Allowance
not actually spent upon restoration of the Premises. Landlord shall not be
liable for any inconvenience or annoyance to Tenant or injury to the business
of Tenant resulting in any way from such damage or the repair thereof, except
that, subject to the provisions of the next sentence, and provided that cash
in the amount of each increment of the Reconstruction Excess shall have been
paid to Landlord by Tenant within ten (10) days after a written request
therefor by Landlord to Tenant, Landlord shall allow Tenant a fair diminution
of Rent during the time and to the extent the Premises are unfit for
occupancy (based upon that portion of Base Rental applicable to the portion
of the Premises subject to such casualty); provided, however, the Premises
shall not be considered unfit for occupancy at any time that (i) such of the
Improvements Restoration has been completed so as to permit occupancy as
evidenced by the issuance of a Certificate of Occupancy or its equivalent for
the Premises by the appropriate governmental entity having jurisdiction over
the Premises for the purpose of issuing such certificate, or (ii) if no such
certificate can be issued by any appropriate governmental entity under
applicable laws, ordinances, or regulations, at such time as the Improvements
Restoration have been substantially completed and tendered to Tenant.

     23.  CONDEMNATION. If the whole or substantially the whole of the
Building or the Premises should be taken for any public or quasi-public use,
by right of eminent domain or otherwise or should be sold in lieu of
condemnation, then this Lease shall terminate as of the date when physical
possession of the Building or the Premises are taken by the condemning
authority. If less than the whole or substantially the whole of the Building
or the Premises are thus taken or sold, Landlord (whether or not the Premises
are affected thereby) may terminate this Lease by giving written notice
thereof to Tenant; in which event this Lease shall terminate as of the date
when physical possession of such portion of the Building or Premises are
taken by the condemning authority. If this Lease is not so terminated upon
any such taking or sale, the Base Rental payable hereunder shall be
diminished by an amount representing that portion of Base Rental applicable
to the portion of the Premises subject to such taking or sale, and Landlord
shall, to the extent Landlord deems feasible, restore the Building and the
Premises to substantially their former condition, but such work shall not
exceed the scope of the work done by Landlord in originally constructing the
Building and installing Shell Improvements and Initial Improvements in the
Premises, nor shall Landlord in any event be required to spend for such work
an amount in excess of the amount received by Landlord as compensation for
such taking. All amounts awarded upon a taking of any part or all of the
Property, Building or the Premises shall belong to Landlord, and Tenant shall
not be entitled to and expressly waives all claims to any such compensation.

     24.  DAMAGES FROM CERTAIN CAUSES. Landlord shall not be liable to Tenant
for any loss or damage to any property or person occasioned by theft, fire,
act of God, public enemy, injunction, riot, strike, insurrection, war, court
order, requisition, or order of governmental body or authority or by any other
cause, except as specifically provided in Paragraph 33 hereof. Nor shall
Landlord be liable for any damage or inconvenience which may arise through
(a) the leasing of other space within the Building to whomsoever Landlord
chooses for whatever use is allowed by Landlord or (b) repair or alteration
of any part of the Building or Premises or to the construction of Leasehold
Improvements for other tenants in the Building, it being specifically
acknowledged and agreed by Tenant that Tenant is leasing space in a Building
which is not fully occupied and that Landlord will, as a part of Landlord's
leasing of other space within the Building, be conducting construction work
in order to prepare other space in the Building, from time to time, for other
tenants.

     25.  EVENTS OF DEFAULT/REMEDIES.

          (a)   The following events shall be deemed to be events of default
by Tenant under this Lease: (i) Tenant shall fail to pay any Rent or other
sum of money due hereunder and such failure shall continue for a period of
five (5) days after the date such sum is due; (ii) Tenant shall fail to
comply with any provision of this Lease or any other agreement between
Landlord and Tenant (including the Work Letter) not requiring the payment of
money, all of which terms, provisions and covenants shall be deemed material
and such failure shall continue for a period of ten (10) days after written
notice of such default is delivered to Tenant; (iii) the Leasehold hereunder
demised shall be taken on execution or other process of law in any action
against Tenant; (iv) Tenant notifies Landlord, at any time prior to the
Commencement Date, that Tenant does not intend to take occupancy of the
Premises upon the commencement of the Lease Term; or Tenant shall fail to
promptly move into and take possession of the Premises when the Premises are
Ready for Occupancy or shall cease to do business in or abandon any portion
of the Premises; (v) Tenant shall become insolvent or unable to pay its debts
as they become due, or Tenant notifies Landlord that it anticipates either
condition; (vi) Tenant takes any action to, or notifies Landlord that Tenant
intends to file a petition under any section or chapter of the Bankruptcy
Code, as amended from time to time, or under any similar law or statute of
the United States or any State thereof; or a petition shall be filed against
Tenant under any such statute; or Tenant or any creditor of Tenant notifies
Landlord that it knows such a petition will be filed; or Tenant notifies
Landlord that it expects such a petition to be filed; or (vii) a receiver or
trustee shall be appointed for Tenant's Leasehold Interest in the Premises or
for all or a substantial part of the assets of Tenant.

          (b)   Upon the occurrence of any event or events of default by
Tenant, whether enumerated in this Paragraph or not, Landlord shall have the
option to pursue any one or more of the following remedies without any notice
[except for such notice expressly required by Subparagraph 25(a)(ii)] or
demand for possession whatsoever (and without limiting the generality of the
foregoing, Tenant hereby specifically waives notice and demand for payment of
Rent or other obligations due and waives any and all other notices or demand
requirements imposed by applicable law): (i) terminate this Lease in which
event Tenant shall immediately surrender the Premises to Landlord; (ii)
terminate Tenant's right to occupy the Premises and re-enter and take
possession of the Premises (without terminating this Lease); (iii) enter upon
the Premises and do whatever


OFFICE LEASE AGREEMENT - Page 6

<PAGE>

Tenant is obligated to do under the terms of this Lease; and Tenant agrees to
reimburse Landlord on demand for any expenses which Landlord may incur in
effecting compliance with Tenant's obligations under this Lease, and Tenant
further agrees that Landlord shall not be liable for any damages resulting to
the Tenant from such action; and (iv) exercise all other remedies available
to Landlord at law or in equity, including, without limitation, injunctive
relief of all varieties.

          (c)   In the event Landlord elects to re-enter or take possession
of the Premises after Tenant's default, Tenant hereby waives notice of such
re-entry or repossession and of Landlord's intent to re-enter or retake
possession. Landlord may, without prejudice to any other remedy which it may
have for possession or arrearages in or future Rent, expel or remove Tenant
and any other person who may be occupying said Premises or any part thereof.
In addition, the provisions of Paragraph 27 hereof shall apply with respect
to the period from and after the giving of notice of such repossession by
Landlord. In addition, Landlord may change or alter the locks and other
security devices on the doors to the Premises and/or remove Tenant's; master
entry cards from the security and master entry card system; and Tenant hereby
waives, to the fullest extent allowed by law, any requirement that notice be
posted on the Premises as to the location of a key to such new locks and any
right to obtain such a key. All Landlord's remedies shall be cumulative and
not exclusive. Forbearance by Landlord to enforce one or more of the remedies
herein provided upon an event of default shall not be deemed or construed to
constitute a waiver of such default. Tenant hereby expressly waives all
rights under Section 93.002 of the Taxes Property Code (Commercial Lockout
Statute).

         (d)   In the event that Landlord elects to terminate this Lease,
then, notwithstanding such termination, Tenant shall be liable for and shall
pay to Landlord the sum of all Rents and other indebtedness accrued to the
date of such termination, plus, as damages, an amount equal to the total of
(i) the cost of recovering the Premises, (ii) the cost of removing and
storing Tenant's and other occupant's property located therein, (iii) the
costs of reletting the Premises, or portion thereof (including, without
limitation, brokerage commissions), (iv) the cost of decorations, repairs,
changes, alterations, and additions to the Premises whether accomplished in
one or more steps or phases, (v) the cost of collecting such amounts from
Tenant hereunder, and (vi) any other sums of money or damages that may be
owed to Landlord as the result of default by Tenant or the exercise of
Landlord's rights at law or in equity.

         (e)   In the event that Landlord elects to take possession of the
Premises and terminate Tenant's right to occupy the Premises without
terminating this Lease, Tenant shall remain liable, and shall pay to
Landlord, from time to time, on demand, any deficiency between the total Base
Rental due under this Lease for the remainder of the Lease Term and rents, if
any, which Landlord is able to collect from another tenant(s) for the
Premises, or portion thereof, during the remainder of the Lease Term ("Rental
Deficiency"). In addition, Tenant shall be liable for and shall pay to
Landlord, on demand, an amount equal to (i) the cost of recovering possession
of the Premises, (ii) the cost of removing and storing Tenant's or any other
occupant's property located therein, (iii) the costs of relating the
Premises, or applicable portion thereof, and whether accomplished in one or
more phases (including, without limitation, brokerage commissions), (iv) the
cost of decorations, changes, alterations, and additions to the Premises, or
applicable portion thereof, and whether accomplished in one or more phases,
(v) the cost of collection of the rent accruing from any such reletting, (vi)
the cost of collecting any sums billable to Tenant by Landlord hereunder, and
(vii) any other sum of money or damages that may owed to Landlord as a result
of Tenant's default or the exercise of Landlord's rights at law or in equity.
Landlord may file suit to recover any sums falling due under the terms hereof
from time to time, and no delivery to or recovery by Landlord of any portion
of the sums due Landlord hereunder shall be any defense in any action to
recover any amount not heretofore reduced to judgment in favor of Landlord.
Nothing contained herein shall be deemed to require Landlord to relet the
Premises. Any sums received by Landlord through reletting shall reduce the
sums owing by Tenant to Landlord hereunder, but in an event shall Tenant be
entitled to any excess of any sums obtained by reletting over and above the
Base Rental provided in this Lease to be paid by Tenant to Landlord. For the
purpose of such reletting, Landlord is authorized to decorate or to make any
repairs, changes, alterations, or additions in and to the Premises or
applicable portion thereof, that Landlord may deem necessary or advisable. No
reletting shall be construed as an election on the part of Landlord to
terminate this Lease unless a written notice of such intention is given to
Tenant by Landlord. Notwithstanding any such reletting without termination,
Landlord may at any time thereafter elect to terminate this Lease for such
previous default. In the alternative (but only in the event that Tenant's
default constitutes a material breach), Landlord may elect to terminate
Tenant's right to occupy the Premises and to immediately recover as damages,
in lieu of the Rental Deficiency, a sum equal to the difference between (i)
the total Base Rental due under this Lease for the remainder of the Lease
Term and (ii) the then fair market rental value of the Premises during such
period, discounted to present value at a rate determined by Landlord, in its
sole discretion ("Discounted Future Rent"). In such event, Landlord shall
have no responsibility to attempt to relet the Premises or to apply any
rentals received by Landlord as a result of any such reletting to Tenant's
obligations hereunder; and the aggregate amount of all damages due to
Landlord, including the Discounted Future Rent hereunder, shall be
immediately due and payable to Landlord upon demand. To the extent Landlord
is obligated by law to mitigate its damages, mitigation for these purposes
shall only mean that Landlord agrees to list or advertise the Premises for
rent in accordance with Landlord's standard advertising and rental policies,
and to rent the Premises to prospective tenants only if there are no other
comparable available leasehold premises in the Building or in other projects
of Landlord or its affiliates in the vicinity of the Building.

         (f)   In addition to the remedies set forth in Paragraph 25(b) of
the Lease, upon the occurrence of any event or events of default by Tenant
under the Lease with respect to which Landlord elects to either terminate the
Lease, or without terminating the Lease, to terminate Tenant's possession of
the Premises, Landlord shall be entitled to (i) receive a cash payment from
Tenant on demand in an amount equal to all "Reimbursable Costs" (as defined
below) which have not yet vested in Tenant, (ii) terminate any remaining
lease concessions which have not yet accrued under the Lease, and (iii)
terminate all of Tenant's parking and signage rights under the Lease. As used
herein, the term "Reimbursable Costs" shall mean the total of (i) the
difference between the average monthly Base Rental payable by Tenant over the
entire Lease Term and the average monthly Base Rental payable by Tenant from
the Commencement Date to the date of default MULTIPLIED BY the number of
months from the Commencement Date through the date of default; and (ii) the
aggregate dollar amount which has been paid and/or is payable by Landlord to
or on behalf of Tenant under the Lease, including, without limitation, (a)
any brokerage commissions in connection with the execution of the Lease, and
(y) any allowances (for leasehold improvements or otherwise). Since the
Reimbursable Costs were incurred by Landlord in reliance upon Tenant fully
performing Tenant's obligations under the Lease. Tenant hereby acknowledges
that Landlord will be damaged, upon a default by Tenant, in an amount equal
to the aggregate dollar value of the Reimbursable Costs which have not yet
vested in Tenant. Reimbursable Costs shall be deemed to be vested in Tenant
on a pro rata bases for each calendar month during the Lease Term for which
Tenant has paid rent and is not otherwise in default hereunder. No vesting
shall occur with respect to any month for which Tenant has not paid rent or
in which Tenant is otherwise in default hereunder.

          (g)   This Paragraph 25 shall be enforceable to the maximum extent
not prohibited by applicable law, and the unenforceability of any portion
thereof shall not thereby render unenforceable any other portion. No act or
thing done by Landlord or its agents during the Lease Term shall be deemed an
acceptance


OFFICE LEASE AGREEMENT - Page 7

<PAGE>

of an attempted surrender of the Premises, and no agreement to accept a
surrender of the Premises shall be valid unless made in writing and signed
by Landlord. No re-entry or taking of possession of the Premises by Landlord
shall be construed as an election on Landlord's part to terminate this Lease
unless a written notice of such termination is given to Tenant.

         (h)   Landlord shall be in default hereunder in the event Landlord
has not begun and pursued with reasonable diligence the cure of any failure
of Landlord to meet its obligations hereunder within thirty (30) days of the
receipt by Landlord of written notice from Tenant of the alleged failure to
perform. In no event shall Tenant have the right to terminate or rescind this
Lease as a result of Landlord's default as to any covenant or agreement
contained in this Lease. Tenant hereby waives such remedies of termination
and rescission and hereby agrees that Tenant's remedies for default hereunder
any for breach of any promise or inducement shall be limited to a suit for
damages and/or injunction. In addition, Tenant hereby covenants that, prior
to the exercise of any such remedies, it will give the mortgagees holding
mortgages on the Building notice and a reasonable time to cure any default
by Landlord.

    26.  PEACEFUL ENJOYMENT. Tenant shall, and may peacefully have, hold, and
enjoy the Premises, subject to the other terms hereof, provided that Tenant
pays the Rent and other sums herein recited to be paid by Tenant and
performs all of Tenant's covenants and agreements herein contained. This
covenant and any and all other covenants of Landlord shall be binding upon
Landlord and its successors only with respect to breaches occurring during its
or their respective periods of ownership of the Landlord's interest
hereunder. Landlord shall be entitled to cause Tenant to relocate from the
Premises to a comparable space (a "Relocation Space") within the Building at
any time upon reasonable written notice to Tenant (which notice shall not be
given in excess of one hundred twenty (120) days prior to such relocation).
Landlord or the third party tenant replacing Tenant in the Premises shall
pay all reasonable costs of accomplishing such relocation. Such a relocation
shall not terminate or otherwise effect or modify this Lease except that from
and after the date of such relocation, "Premises" shall refer to the
Relocation Space into which Tenant has been moved, rather than the original
Premises as herein defined.

    27.  HOLDING OVER. In the event of holding over by Tenant after
expiration or other termination of this Lease or in the event Tenant
continues to occupy the Premises after the termination of Tenant's right of
possession pursuant to Paragraph 25(b) hereof, Tenant shall, throughout the
entire holdover period, pay Rent equal to one hundred fifty percent (150%) of
the Base Rental and additional Base Rental which would have been applicable
had the term of this Lease continued through the period of such holding over
by Tenant. No holding over by Tenant after the expiration of the term of
this Lease shall be construed to extend the term of this Lease.

    28.  SUBORDINATION TO MORTGAGE. Tenant accepts this Lease subject and
subordinate to any mortgage, deed of trust or other lien presently existing
or hereafter arising upon the Premises, or upon the Building and/or the
Property and to any renewals, modifications, consolidations, refinancing, and
extensions thereof, but Tenant agrees that any such mortgagee shall have the
right at any time to subordinate such mortgage, deed of trust or other lien
to this Lease on such terms and subject to such conditions as such mortgagee
may deem appropriate in its discretion. Landlord is hereby irrevocably vested
with full power and authority to subordinate this Lease to any mortgage, deed
of trust or other lien now existing or hereafter placed upon the Premises, or
the Building and/or the Property and Tenant agrees upon demand to execute
such further instruments subordinating this Lease or attorning to the holder
of any such liens as Landlord may request. The terms of this Lease are
subject to approval by the Landlord's permanent lender(s), and such approval
is a condition precedent to Landlord's obligations hereunder. In the event
that Tenant should fail to execute any subordination or other agreement
required by this Paragraph promptly as requested, Tenant hereby irrevocably
constitutes Landlord as its attorney-in-fact to execute such instrument in
Tenant's name, place and stead, it being agreed that such power is one
coupled with an interest. Tenant agrees that it will from time to time upon
request by Landlord execute and deliver to such persons as Landlord shall
request a statement in recordable form certifying that this Lease is
unmodified and in full force and effect (or, if there have been
modifications, that the same is in full force and effect as so modified),
stating the dates to which Rent and other charges payable under this Lease
have been paid, stating the Landlord is not in default hereunder (or if
Tenant alleges a default stating the nature of such alleged default) and
further stating such other matters as Landlord shall reasonably require.

    29.  ESTOPPEL CERTIFICATES. Tenant agrees that it will from time to time
upon request by Landlord execute and deliver to such persons as Landlord
shall request a statement in recordable form certifying that this Lease is
unmodified and in full force and effect (or if there have been modifications,
that the same is in full force and effect as so modified), stating the date
to which rental and other charges payable under this Lease have been paid,
stating that the Landlord is not in default hereunder (or, if Tenant alleges
a default stating the nature of such alleged default in particularity) and
further stating such other matters as Landlord shall reasonably require.
Tenant agrees to deliver such statement within ten (10) days after written
request from Landlord. Failure to timely deliver such estoppel certificate
shall be a default under this Lease and shall entitle Landlord to pursue any
and all remedies it deems appropriate.

    30.  LANDLORD'S LIEN. Tenant hereby grants to Landlord a lien and
security interest on all property of Tenant now or hereafter placed in or
upon the Premises and such property shall be and remain subject to such lien
and security interest of Landlord for payment of all Rent and other sums
agreed to be paid by Tenant herein. The provisions of this Paragraph relating
to such lien and security interest shall constitute a security agreement
under and subject to the Texas Business and Commerce Code so that Landlord
shall have and may enforce a security interest on all property of Tenant now
or hereafter placed in or on the Premises, in addition to and cumulative of
the Landlord's liens and rights provided by law or by other terms and
provisions of this Lease. Tenant agrees to execute as debtor such financing
statement or statements as Landlord may now or hereafter request. Landlord
may at its election at any time file a copy of this Lease as a financing
statement. Notwithstanding the above, Landlord shall neither sell nor
withhold from Tenant, Tenant's business records. Tenant hereby waives its
lien rights under Section 91.004 of the Texas Property Code.

    31.  ATTORNEY'S FEES. In the event either party files suit to enforce the
performance of or obtain damages caused by a default under any of the terms
of this Lease, the party against whom a judgment is rendered shall pay the
prevailing party's reasonable costs and attorneys' fees. The reasonableness
of such costs and attorneys' fees shall be determined by the court and not
the jury, with respect to any monetary claim, in order for a party to
prevail, such party must be award at least fifty percent (50%) of the highest
amount which such party claimed at any time in such suit.

    32.  NO IMPLIED WAIVER. The failure of Landlord to insist at any time upon
the strict performance of any covenant or agreement herein or to exercise any
option, right, power or remedy contained in this Lease shall not be construed
as a waiver or a relinquishment thereof for the future. No payment by Tenant
or receipt by Landlord of a lesser amount than the monthly installment of Rent
due under this Lease shall be deemed to be other than on account of the
earliest Rent due hereunder, nor shall any endorsement or statement on any
check or any letter accompanying any check or payment as Rent be deemed an
accord and satisfaction, and Landlord may


OFFICE LEASE AGREEMENT - Page 8

<PAGE>

accept such check or payment without prejudice to Landlord's right to recover
the balance of such Rent or pursue any other remedy in this Lease provided.

     33.  PERSONAL LIABILITY. In no event shall Landlord be liable to Tenant
either for (a) any loss or damage that may be occasioned by or through the
acts or omissions of other tenants of the Building or of any other persons
whomever or (b) any consequential damages regardless of causation. With
respect to tort claims against Landlord, Landlord shall not be liable to
Tenant or to any other person for any act or omission of Landlord or of its
agents or employees, negligent or otherwise, except for actual damages or
costs incurred as a direct result of and caused directly by the willful
misconduct or gross negligence of Landlord (or of Landlord's agents or
employees) in circumstances in which Landlord is deemed to be liable at law
for such acts or omissions and such liability cannot be waived by Tenant.
Nothing contained in the immediately preceding sentence shall ever be
construed as creating liability in excess of that existing at law or, in any
event, increasing the liability of Landlord, under any theory or cause of
action, however denominated, from that existing at law, further, the
liability of Landlord to Tenant for (a) any default by Landlord under the
terms of this Lease, (b) for any tort liability of Landlord to Tenant, or (c)
in any other circumstance in which Landlord is judicially determined to have
some liability to Tenant, for whatever reason, shall, in each such instance,
be limited to the interest of Landlord in the Building and Property and
Tenant agrees to look solely to Landlord's interest in the Building and the
Property for the recovery of any judgment from the Landlord, if being
intended that Landlord shall never be personally liable for any judgment or
deficiency.

     34.  SECURITY DEPOSIT. The Security Deposit shall be held by Landlord
without liability for interest and as security for the performance by Tenant
of Tenant's covenants and obligations under this Lease, it being expressly
understood that the Security Deposit shall not be considered an advance
payment of Rental or a measure of Tenant's liability for damages in case of
default by Tenant. Landlord may commingle the Security Deposit with
Landlord's other funds. Landlord may, from time to time, without prejudice to
any other remedy, use the Security Deposit to the extent necessary to make
good any arrearages of Rent or to satisfy any other covenant or obligation of
Tenant hereunder. Following any such application of the Security Deposit,
Tenant shall pay to Landlord on demand the amount so applied in order to
restore the Security Deposit to its original amount. If Tenant is not in
default at the termination of this Lease, the balance of the Security Deposit
remaining after any such application shall be returned by Landlord to Tenant.
If Landlord transfers its interest in the Premises during the term of this
Lease, Landlord may assign the Security Deposit to the transferee and
thereafter shall have no further liability for the return of such Security
Deposit.

     35.  NOTICE. Any notice in the Lease provided for must, unless otherwise
expressly provided herein, be in writing, and may, unless otherwise in this
Lease expressly provided, be given or be served by depositing the same in the
United States mail, postage prepaid and certified and addressed to the party
to be notified, with return receipt requested, or by prepaid telegram, or by
overnight courier (such as Federal Express or similar company) or by hand
delivery, with evidence in either event of delivery to addressee, when
appropriate, addressed to the party to be notified at the address stated in
this Lease or such other address notice of which has been given to the other
party. Notice deposited in the mail in the manner hereinabove described shall
be effective from and after the expiration of three (3) calendar days after
it is so deposited. Notice by overnight courier shall be effective on the
next business day after being sent. Notice by personal delivery shall be
effective on the day of receipt.

     36.  SEVERABILITY. If any term or provision of this Lease, or the
application thereof to any person or circumstances shall, to any extent, be
invalid or unenforceable, the remainder of this Lease, or the application of
such term or provision to persons or circumstances other than those as to
which it is held invalid or unenforceable, shall not be affected thereby, and
each term and provision of this Lease shall be valid and enforced to the
fullest extent permitted by law.

     37.  RECORDATION. Tenant agrees not to record this Lease or any
memorandum hereof.

     38.  GOVERNING LAW. This Lease and the rights and obligations of the
parties hereto shall be interpreted, construed, and enforced in accordance
with the laws of the State of Texas.

     39.  FORCE MAJEURE. Whenever a period of time is herein prescribed for
the taking of any action by Landlord, Landlord shall not be liable or
responsible for, and there shall be excluded from the computation of such
period of time, any delays due to strikes, riots, acts of God, shortages of
labor or materials, war, governmental laws, regulations or restrictions,
litigation brought by third parties to enjoin Landlord's activities at the
Building, or any other cause whatsoever beyond the control of Landlord.

     40.  TIME OF PERFORMANCE. Except as expressly otherwise herein provided,
with respect to all required acts of Tenant, time is of the essence of this
Lease.

     41.  TRANSFERS BY LANDLORD. Landlord shall have the right to transfer
and assign, in whole or in part, all its rights and obligations hereunder and
in the Building and Property referred to herein, and in such events and upon
such transfer Landlord shall be released from any further obligations
hereunder, and Tenant agrees to look solely to such successor in interest of
Landlord for the performance of such obligations.

     42. TRANSFERS BY TENANT. Tenant shall not transfer, convey, mortgage,
pledge, hypothecate, or encumber Tenant's leasehold interest hereunder or
grant any license, concession, or other right to occupancy of any portion of
the Premises without the prior written consent of Landlord, which may be
granted or withheld in Landlord's sole discretion. The prohibitions specified
in this Paragraph 42 shall be in addition to, and independent of, the
provisions of Paragraph 13 hereof and shall be construed to include, without
limitation, any such prohibited transfers occurring by operation of law. Any
attempt by Tenant to accomplish a transfer prohibited by the provisions of
this Lease, without having obtained the prior written consent of Landlord
thereto shall be void and of no force or effect any may, at the option of
Landlord, constitute a material default hereunder.

     43.  COMMISSIONS. Tenant represents and warrants that no broker has
represented it in this lease transaction and that no broker is owed a
commission or fee in connection with the consummation of this lease
transaction. Tenant hereby indemnifies and holds Landlord harmless against
any loss, claim, expense or liability with respect to any commissions or
brokerage fees claimed on account of the execution and/or renewal of this
Lease or the expansion of the Premises hereunder, if applicable, due to any
action by Tenant. The provisions of this paragraph shall survive the
termination of this Lease.

     44.  EFFECT OF DELIVERY OF THIS LEASE. Landlord has delivered a copy of
this Lease to Tenant for Tenant's review only, and the delivery hereof does
not constitute an offer to Tenant or option. This Lease shall not be effective
until a copy executed by both Landlord and Tenant is delivered to and
accepted by Landlord, and this Lease has been approved by Landlord's
mortgagee.

     45.  ENTIRE AGREEMENT. This Lease embodies the entire agreement between
the parties hereto with

OFFICE LEASE AGREEMENT - Page 9

<PAGE>

relation to the transaction contemplated hereby, and there have been and are
no covenants, agreements, representations, warranties or restrictions between
the parties hereto with regard thereto other than those specifically set forth
herein.

    46.  RECEIPT OF PREMISES. The occupancy of the Premises by Tenant shall
constitute the acknowledgment and agreement of Tenant that Tenant is fully
familiar with the physical condition of the Premises, that Tenant has received
the same in good order and condition, and that the Premises comply in all
respects with the requirements of this Lease and are suitable for the purposes
for which the Premises are hereby leased. In that regard, Landlord hereby
disclaims, and Tenant hereby waives, any warranty of suitability with respect
to the Premises.

    47.  MERGER OF ESTATES. The voluntary or other surrender of this Lease by
Tenant or a mutual cancellation thereof, shall not constitute a merger; and
upon such surrender or cancellation of this Lease, Landlord shall have the
option, in Landlord's sole discretion, to (i) either terminate all or any
existing subleases or subtenancies, or (ii) assume Tenant's interest in any
or all subleases or subtenancies.

    48.  WASTE MANAGEMENT. Without limiting its obligations under Paragraph
14 (and the rules and regulations attached to this Lease as EXHIBIT "D"),
Tenant covenants and agrees to comply with all laws, rules, regulations and
guidelines now or hereafter made applicable to the Premises respecting the
disposal of waste, trash, garbage and other matter (liquid or solid),
generated by Tenant, the disposal of which is not otherwise the express
obligation of Landlord under this Lease (it is expressly understood that the
provision of janitorial services by Landlord is not an express obligation of
Landlord under this Lease for the purpose of this Paragraph 48), including,
but not limited to, laws, rules, regulations and guidelines respecting
recycling and other forms of reclamation (all of which are herein
collectively referred to as "Waste Management Requirements"). Tenant
covenants and agrees to comply with Waste Management Requirements applicable
to Landlord (i) as owner of the Premises and (ii) in performing Landlord's
obligations under this Lease, if any. Tenant further covenants and agrees to
comply with all rules and regulations established by Landlord to enable
Landlord from time to time to avail itself of the lowest rate available for
the disposal of waste, trash, garbage and other matter (liquid or solid),
generated by Tenant. Tenant covenants and agrees to indemnify, defend,
protect and hold Landlord harmless (in accordance with Paragraph 20) from and
against all liability (including costs, expenses and attorney fees) that
Landlord may sustain by reason of Tenant's breach of its obligations under
this paragraph 48. Tenant's obligations under this paragraph 48 shall survive
the termination of this Lease.

    49.  AMERICANS WITH DISABILITIES ACT AND TEXAS ARCHITECTURAL BARRIERS
ACT. Tenant agrees to comply with all requirements of the Americans with
Disabilities Act (Public Law 101-336 (July 26, 1990)) and the Texas
Architectural Barriers Act (Article 9102, Tex. Rev. Civ. St. (1991))
applicable to the Premises and applicable to the Building and Property to
accommodate its employees, invitees and customers. Tenant acknowledges that
it shall be wholly responsible for any accommodations or alterations which
need to be made to the Premises to accommodate Tenant's employees, customers
and invitees and for making any additional accommodations or alterations
which need to be made to the Building or the Property to accommodate Tenant's
employees, invitees and customers. Tenant agrees to indemnify and hold
Landlord harmless from any and all expenses, liabilities, costs or damages
suffered by Landlord as a result of Tenant's failure to fulfill its aforesaid
responsibilities regarding making such accommodations and alterations
referenced in the preceding sentence. No provision in this Lease should be
construed in any manner as permitting, consenting to or authorizing Tenant to
violate requirements under either such Act and any provision of the Lease
which could arguably be construed as authorizing a violation of either Act
shall be interpreted in a manner which permits compliance with such Act and
is hereby amended to permit such compliance.

    50.  TEMPORARY SPACE. The parties acknowledge that from the date of
execution of this Lease through the Commencement Date (the "Temporary Space
Term"), Tenant shall have the right to occupy that certain space as shown on
EXHIBIT "H" attached hereto ("Temporary Space") of the Building at no charge.
During the Temporary Space Term, all terms and provisions of this Lease other
than those with respect to Rent, the Allowance and the Lease Term shall apply
with respect to the Temporary Space. Further, nothing contained herein shall
be construed as releasing Tenant from any obligations of Tenant arising under
Paragraph 20, Indemnity, of this Lease or with respect to any physical damage
to the Temporary Space, which shall survive the Temporary Space Term.

                           OFFICE LEASE AGREEMENT BETWEEN
                        METROPOLITAN LIFE INSURANCE COMPANY,
                    AND METROPOLITAN TOWER REALTY COMPANY, INC.
                                 AS LANDLORD, AND
                              CALIBRE ENERGY, L.P.,
                                     AS TENANT

                          PAYMENT OF EXCESS BASIC COSTS

     1.   BASIC COSTS. The Base Rental payable hereunder shall be adjusted
from time to time in accordance with the following provisions:

          (a)   Tenant's Base Rental is based, in part, upon the estimate
     that annual "Basic Costs" (as hereinafter defined) will be equal to the
     "Expense Stop". During the Lease Term, Tenant shall pay as an adjustment
     to Base Rental hereunder an amount (per each square foot of Rentable
     Area within the Premises) equal to the excess ("Excess") from time to
     time of Basic Costs per square foot of Rentable Area in the Building
     over the Expense Stop. Landlord may collect such additional Base Rental
     in arrears on a yearly basis. Landlord shall also have the option to
     make a good faith estimate of the Excess from time to time for each
     upcoming calendar year (or remainder thereof, if applicable) and, upon
     thirty (30) days' written notice to Tenant, may require the monthly
     payment of Base Rental to be adjusted in accordance with such estimate.
     Any amounts paid based on such an estimate shall be subject to
     adjustment pursuant to Paragraph 2 below when Basic Costs are available
     for such calendar year.

          (b)   "Basic Costs" shall mean all direct and indirect costs and
     expenses in each calendar year of operating, maintaining, repairing,
     managing and owning the Building and the Property plus all operating
     costs of the Exterior Common Area (below defined). Basic Costs shall not
     include the cost of capital improvements, depreciation, interest, lease
     commissions, and principal payments on mortgage and other non-operating
     debts of Landlord. Basic Costs shall, however, include the amortization
     of capital improvements which are primarily for the purpose of reducing
     Basic Costs, or which are required by governmental authorities.
     "Exterior Common Areas" shall mean that portion of the Property (and
     other tracts of real property comprising the multi-building project in
     the event the Building is located in such a project) which are not
     located within the Building (or other building in a multi-building
     project) and which are provided and maintained for the common use and
     benefit of Landlord and tenants of the Building (or multi-building
     project) generally and the employees, invitees and licensees of Landlord
     and such tenants; including without limitation, all parking areas
     (enclosed or otherwise, including, without limitation, the parking areas
     beneath the Building and those in the 1400 Louisiana Garage) and all
     streets, sidewalks, walkways, pedestrian tunnels and landscaped areas.

     2.   PROCEDURE. The following additional provisions shall apply to
     Paragraph 1 of this EXHIBIT "C":

          (a)   By April 1 of each calendar year during Tenant's occupancy, or
     as soon thereafter as practical, Landlord shall furnish to Tenant a
     statement of Landlord's Basic Costs for the previous calendar year. If
     for any calendar year additional Base Rental was collected for the prior
     year, as a result of Landlord's estimate of Basic Costs, in excess of
     the additional Base Rental due during such prior year, then Landlord
     shall refund to Tenant any over payment (or at Landlord's option, apply
     such amount against rentals due or to become due hereunder). Likewise,
     Tenant shall pay to Landlord, on demand, any underpayment with respect
     to the prior year. In no event shall Basic Costs per square foot of
     Rentable Area within the Building be deemed to be less than the Expense
     Stop, it being the intent of Landlord and Tenant that Tenant shall at
     all times be responsible for the payment of, and shall pay, not less
     than the amount of Base Rental for the applicable period (before
     adjustment) specified in this Lease.

          (b)   Notwithstanding any language in the Lease or in this EXHIBIT
     "C" seemingly to the contrary, Landlord shall determine and estimate
     Basic Costs for any calendar year within the Lease Term by increasing
     the variable components of Basic Costs to the amount which Landlord
     projects would have been incurred had the Building been occupied to the
     extent of ninety-five percent (95%) of the Rentable Area therein during
     all of the applicable calendar year. In such event, the term "Basic
     Costs", as used in this EXHIBIT "C" and in the Lease, shall include
     (i) the actual Basic Cost incurred during any portion of such calendar
     year in which the Building is occupied to the extent of ninety-five percent
     (95%) or more of the Rentable Area therein plus (ii) the Basic Costs
     which would have been incurred had the Building been occupied to the
     extent of ninety-five percent (95%) of the Rentable Area thereof during
     the portion of that calendar year in which the actual occupancy of the
     Building is less than ninety-five percent (95%) of the Rentable Area
     therein; and Landlord shall have the option of making such estimate in
     advance for any upcoming calendar year.

          (c)   In the event that the Lease Term commences on a day other
     than January 1 or terminates on a day other than December 31, the Excess
     for that part of the first (1st) calendar year or last calendar year
     during the Lease Term shall be determined as follows:

               (i)     The Expense Stop shall be prorated based upon the
     number of months in such partial calendar year. With respect to any
     partial calendar month occurring during such partial calendar year, the
     Expense Stop shall also be prorated based upon the number of days in
     that partial calendar month.

               (ii)    The Excess, if any, for the applicable partial
     calendar year shall then be the amount by which (A) actual Basic Costs
     per square foot of Rentable Area in the Building for such calendar year,
     prorated based upon the number of months and days in the applicable
     partial calendar year, exceed (B) the Expense Stop, as prorated pursuant
     to the provisions of this Subparagraph 2(c).

               (iii)   With respect to a proration for the first (1st)
     calendar year and in the event that Landlord's estimate of the Basic
     Costs to be incurred during such partial calendar year exceeds the
     Expense Stop, as prorated pursuant to the provisions of this
     Subparagraph 2(c), Landlord may, upon thirty (30) days prior written
     notice to Tenant, require the monthly payments of Base Rental occurring
     during such partial calendar year to be adjusted in accordance with such
     estimate.

               (iv)    The provisions of this EXHIBIT "C" shall survive the
     termination of the Lease Term.

                               CALIBRE ENERGY, L.P.,
                                    AS TENANT


                             RULES AND REGULATIONS

    1.   The sidewalks, halls, passages, exits, entrances, elevators,
escalators and stairways of the Building shall not be obstructed by any of
the tenants or used by them for any purpose other than for ingress to and
egress from their respective premises. The halls, passages, exits, entrances,
elevators, escalators and stairways are not for the use of the general
public, and Landlord shall in all cases retain the right to control and
prevent access thereto of all persons whose presence in the judgment of
Landlord shall be prejudicial to the safety, character, reputation and
interests of the Building and its tenants, provided that nothing herein
contained shall be construed to prevent such access to persons with whom any
tenant normally deals in the ordinary course of its business, unless such
persons are engaged in illegal activities. No tenants and no employee, agent
or invitee of any tenant shall go upon the roof of the Building. The two (2)
emergency stairwells located on each floor of the Building shall not be
obstructed by tenants or used by tenants or tenant's agents, servants,
employees, invitees or contractors or the public in general for any reason or
purpose except as an escape route in the event of an emergency.

    2.   No sign, placard, picture, name, advertisement or notice, visible
from the exterior of any tenant's premises shall be inscribed, painted,
affixed or otherwise displayed by any tenant on any part of the Building
without the prior written consent of Landlord, and Landlord shall have the
right to remove any such sign, placard, picture, name, advertisement or
notice at the expense of the tenant responsible for same and without notice
to such tenant. If Landlord shall have given such consent at anytime, such
consent shall be deemed to relate only to the particular sign, placard,
picture, name, advertisement or notice so consented to by Landlord and shall
not be construed as dispensing with the necessity of obtaining the specific
written consent of Landlord with respect to each and every other sign,
placard, picture, name, advertisement or notice. Landlord will adopt and
furnish to Tenant uniform rules and regulations relating to signs on the
office floors which shall be applicable to all tenants occupying space on the
office floors of the Building and tenant agrees to conform to such rules and
regulations. All approved signs or lettering on doors of Tenant's Premises
shall be printed, painted, affixed or inscribed at the expense of Tenant by a
person approved by Landlord.

    3.   The premises shall not be used for the storage of merchandise or for
lodging. No cooking, other than for warming purposes, shall be done or
permitted by any tenant in the Building, except that the preparation of
coffee, tea, hot chocolate and similar items for tenants and their employees
shall be permitted.

    4.   No tenant shall employ any person or persons other than the janitor
of Landlord for the purpose of cleaning the premises, unless otherwise agreed
to by Landlord in writing. Except with the written consent of Landlord, no
person or persons other than those approved by Landlord shall be permitted to
enter the Building for the purpose of cleaning the same. No tenant shall
cause any unnecessary labor by reason of such tenant's carelessness or
indifference in the preservation of good order and cleanliness. Landlord
shall in no way be responsible to any tenant for any loss of property on the
premises, however occurring, or for any damage done to the furniture or other
effects of any tenant by the janitor or any other employee or any other
person. Janitor service shall include ordinary dusting and cleaning by the
janitor assigned to such work and shall not include shampooing of carpets or
rugs or moving of furniture or other special services. Janitor services will
not be furnished on nights when rooms are occupied after 9:30 p.m.

    5.   No animals, or birds, or bicycles shall be allowed in the offices,
halls, corridors, elevators or elsewhere in the Building, except for seeing
eye dogs or other service animals for disabled persons.

    6.   Landlord will furnish each tenant with two (2) keys free of charge.
Landlord may make a reasonable charge for any additional keys. No tenant
shall have any keys made except by Landlord. No tenant shall alter any lock
or install any lock or install a new or additional lock or any bolt on any
door of its premises without prior written consent of Landlord. If Landlord
shall give its consent, the tenant shall in each case furnish Landlord with a
key for any such lock. Each tenant upon the termination of its tenancy, shall
deliver to Landlord all keys to doors in the Building which shall have been
furnished to tenant.

    7.   No safes, electronic equipment or other objects larger or heavier
than that which the freight elevators of the Building are limited to carry
shall be brought into or installed on any premises without Landlord's prior
written approval, it being agreed that Landlord shall approve the moving in
and installation of tenant's vault. The moving of such equipment shall occur
only between such hours as may be designated by, and only upon previous
notice to, the manager of the Building. No freight, furniture or bulky matter
of any description shall be received into the Building or carried into the
elevators, except during hours and in a manner approved by Landlord. Landlord
shall have the right to prescribe the weight, size and position of all safes
and other heavy equipment brought into the Building. Safes or other heavy
objects shall, if considered necessary by Landlord, stand on wood strips of
such thickness as is necessary to properly distribute the weight. Landlord
will not be responsible for loss of or damage to any such safe or property
from any cause, and all damage done to the Building by moving or maintaining
such safe or other property shall be repaired at the expense of tenant.

    8.   No tenant shall use or keep in, on or about the premises of the
Building any kerosene, gasoline or inflammable or combustible fluid or
material, or use any method of heating or air conditioning other than that
supplied by Landlord. No tenant shall use, keep or permit to be used or kept
any foul or noxious gas or substance in, on or about the premises, or permit
or suffer the premises to be occupied or used in a manner offensive or
objectionable to Landlord or other occupants of the Building by reason of
noise, odors and/or vibrations, or interfere in any way with other tenants or
those having business therein.

    9.   Landlord shall have the right, exercisable without notice and
without liability to any tenant, to change the name and street address of the
Building.

    10.  Landlord reserves the right to exclude from the Building between the
hours of 7:00 p.m. and 7:00 a.m. and at all hours on Sundays, legal holidays
and after 1:00 p.m. on Saturdays all persons who do not present a pass to the

any tenant requests the same in writing. Each tenant shall be responsible for
all persons for whom it requests passes and

shall be liable to Landlord for all acts to such person. Landlord shall in no
case be liable for damages for any error with regard to the admission to or
exclusion from the Building of any person. In the case of invasion, mob,
riot, public excitement, or other circumstances rendering such action
advisable in Landlord's opinion, Landlord reserves the right to prevent
access to the Building during the continuance of the same by such actions as
Landlord may deem appropriate, including closing and locking doors.

     11.  The directory board of the Building will be provided for the
display of the name and location of tenants only, and Landlord reserves the
right to exclude any other names therefrom. Any additional name which tenant
shall desire to place upon said directory board over and above the allowance
set forth in the Lease must first be approved by Landlord, and if so
approved, a charge will be made therefor.

     12.  No curtains, draperies, blinds, shutters, shades, screens or other
coverings, hanging or decorations shall be attached to, hung or placed in, or
used in connection with any window of the Building without the prior written
consent of Landlord. In any event, with the prior written consent of
Landlord, said above items shall be installed inboard of Landlord's standard
window covering and shall in no way be visible from the exterior of the
Building.

     13.  No tenant shall obtain for use in the premises, ice, drinking

or bootblacking services in the premises, except from persons authorized by
Landlord, and at hours and under regulations fixed by Landlord, except as
otherwise set forth in the Lease.

off-duty policemen attend the party. One (1) policeman should remain in the
suite during the party, and one (1) should position himself near the proper
elevator bank.

     15.  Tenant shall see that the doors of its premises are closed and
securely locked and must observe strict care and caution that all water
faucets, water apparatus and utilities are shut off before tenant or tenant's
employees leave the premises, do as to prevent waste or damage. On
multiple-tenancy floors, all tenants shall keep the door or doors to the
Building corridors closed at all times except for ingress and egress.

     16.  The toilet rooms, toilets, urinals, wash bowls and other apparatus
shall not be used for any purpose other than that for which they were
constructed. No foreign substance of any kind whatsoever shall be thrown
therein. The expense of any breakage, stoppage or damage resulting from the
violation of this rule shall be borne by the tenant who, or whose employees,
agents or invitees, shall have caused it.

     17.  Except with the prior written consent of Landlord, no tenant shall
sell, or permit the sale of newspapers, magazines, periodicals, theatre
tickets or any other goods of merchandise in or on the premises, nor shall
any tenant carry on, or permit or allow any employee or other person to carry
on, the business of stenography, typewriting or any similar business in or
from the premises for the services or accommodation of occupants of any other
portion of the Building.

     18.  No tenant shall install any radio or television antenna,
loudspeaker or other device on the roof or exterior walls of the Building.

     19.  No hand trucks or dollies, except those equipped with rubber tires
and side guards, shall be used in any space or in public halls of the
Building by any tenant. No other vehicles of any kind shall be brought into
the Building or kept in or about any premises by any tenant, their employees,
agents or invitees.

     20.  Each tenant shall store all its trash and garbage within its
premises. No material shall be placed in the trash boxes or receptacles if
such material is of such nature that it may not be disposed of in the
ordinary and customary manner of removing and disposing of trash and garbage
in the City of Houston, without being in violation of any law or ordinance
governing such disposal.  All garbage and refuse disposal shall be made only
through entryways and elevators provided for such purposes and at such times
as Landlord shall designate.

     21.  Canvassing, soliciting and peddling in the Building are prohibited
and each tenant shall cooperate to prevent the same.

     22.  The requirements of the tenants will be attended to only upon
application at the office of the Building. Employees of Landlord shall not
perform any work or do anything outside of their regular duties unless under
special instructions from Landlord.

     23.  Landlord may waive any one or more of these Rules and Regulations
for the benefit of any particular tenant or tenants, but no such waiver by
Landlord shall be construed as a waiver of such Rules and Regulations in
favor of any other tenant or tenants, nor prevent Landlord from thereafter
enforcing any such Rules and Regulations against any or all of the tenants of
the Building.

     24.  These Rules and Regulations are in addition to and shall not be
construed to in any way modify, alter or amend, in whole or in part, the
terms, covenants, agreements and conditions of any lease of premises in the
Building.

     25.  Landlord reserves the right to make such other and reasonable rules
and regulations as in its judgment may from time to time be needed for the

                                   WORK LETTER

                              (Minor Refurnishment)

    This Work Letter ("Work Letter") describes and specifies the rights and
obligations of Landlord and Tenant with respect to certain remodeling and
refurbishment items to be completed in the Premises.

    1.   DEFINITIONS. Terms which are defined in the Lease shall have the
same meaning in this Work Letter. Additionally, as used in this Work Letter,
the following terms shall have the following meanings:

         (a)   ALLOWANCE: An amount equal to but not in excess of $5,164.00
to be used to complete the Refurbishment Items.

         (b)   COST OF THE WORK: The cost of all materials and labor needed to
complete the installation of the Refurbishment Items.

         (c)   REFURBISHMENT ITEMS: The items of work to be completed in the
Premises are itemized on Schedule "E-1" attached hereto.

    2.   COLOR, FINISHES AND MATERIALS. Each of the Refurbishment Items shall
be completed using building standard materials and workmanship. As
applicable, Tenant agrees to select all colors, finishes and building
material types within five (5) days of the execution of this Lease, and if
such selections are not made within such date, Landlord may in its sole
discretion select any building standard materials, colors and finishes
available for such Refurbishment Items. Tenant shall furnish a space plan or
diagram depicting the desired location for the Refurbishment Items within
five (5) days after the execution of this Lease, and if not furnished within
such date, or if the locations so designated are not acceptable to Landlord
for any reason, then Landlord may instead install such items in locations
acceptable to Landlord.

    3.   PERFORMANCE OF THE WORK AND COSTS. Landlord shall perform as
construction manager to cause the Refurbishment Items to be completed, and
the Cost of the Work shall include a management fee payable to Landlord in
the amount of five percent (5%) of the cost of the materials and labor needed
to complete the installation of the Refurbishment Items. Tenant shall be
obligated to pay the Cost of the Work in excess of the Allowance. Provided,
however, nothing in this Work Letter should be construed as imposing an
obligation on Landlord to complete the Refurbishment Items if the Cost of the
Work is reasonably estimated by Landlord to exceed the Allowance. If the Cost
of the Work is likely to exceed the Allowance, Landlord may, in its
discretion, either complete those items which, in the aggregate, Landlord
determines will not exceed the Allowance, or Landlord may make demand upon
tenant to deposit an amount equal to the estimated excess necessary to
complete the Refurbishment Items, and Tenant's failure to deposit such amount
shall relieve Landlord from any further obligation to complete any of the
Refurbishment Items. Any cost savings achieved after completion of all
Refurbishment Items shall be the property of Landlord, not Tenant, unless the
final Cost of the Work exceeds the Allowance amount and sums are deposited by
Tenant as aforesaid, in which case any surplus monies remaining after
completion of construction shall be the property of Tenant.

    4.   OTHER. Except for the Refurbishment Items, Tenant is taking the
Premises "As-Is" in its current condition and without benefit of further
improvements. The agreement of Landlord to perform the Refurbishment Items
should not be construed as representing or warranting that such work will
render the Premises in compliance with any applicable laws, including the
Americans with Disabilities Act and the Texas Architectural Barriers Act, and
it shall remain the sole responsibility of Tenant to determine whether the
Premises, with or without completion of the Refurbishment Items, comply with
all applicable laws. Within fifteen (15) days after Landlord advises Tenant
that the Refurbishment Items are completed, Tenant shall give Landlord a
written punchlist specifying any details which remain to be performed by
Landlord with respect to any work described in this Work Letter; and except
for the details contained in such written punchlist from Tenant, all
obligations of Landlord in regard to such work shall be deemed to have been
satisfied. Landlord shall have the right to enter the Premises to complete
any such unfinished details, and entry by Landlord, its agents, servants,
employees or contractors for such purpose shall not relieve Tenant of any of
its obligations under the Lease or impose any liability on Landlord or its
agents, servants, employees or contractors. This Work Letter embodies all
representations, warranties and agreements of Landlord and Tenant with respect
to the matters described herein, and this Work Letter may not be altered or
modified except by an agreement in writing signed by both parties. In the
event of conflict between the terms of this Work Letter and any other
exhibits or addenda to this Lease, this Work Letter shall prevail.

                               EXHIBIT "F"

                                   TO
                      OFFICE LEASE AGREEMENT BETWEEN
                   METROPOLITAN LIFE INSURANCE COMPANY
                AND METROPOLITAN TOWER REALTY COMPANY, INC.,
                             AS LANDLORD, AND
                           CALIBRE ENERGY, L.P.,
                                 AS TENANT


                                 PARKING


     This EXHIBIT "F" ("Parking Exhibit") describes and specifies Tenant's
non-exclusive right to use zero (O) reserved parking spaces and six (6)
unreserved parking spaces (collectively, "Spaces") located on such levels
inside one or more of the Building's parking garages as set forth on SCHEDULE
1 attached to this Parking Exhibit and incorporated herein by reference, all
upon the terms and conditions set forth below. The parking garage beneath the
Building shall be referred to as the "Building Garage." The parking garage
located at 1400 Louisiana shall be referred to as the "1400 Louisiana
Garage." The parking garage located at 777 Clay shall be referred to as the
"777 Clay Garage." The Building Garage, 1400 Louisiana Garage and 777 Clay
Garage may be hereinafter referred to individually and collectively as the
"Parking Garage."

     1.   DEFINITIONS. The terms which are defined in the Lease shall have
the same meaning in this Parking Exhibit.

     2.   GRANT AND RENTAL FEE. Provided no event of default has occurred and
is continuing under the Lease, Tenant shall be permitted the non-exclusive use
of the Spaces during the Lease Term at such monthly rates (together with any
applicable tax thereon) and subject to such terms, conditions, and
regulations as are, from time to time, promulgated by Landlord or the manager
of the Parking Garage, as applicable, and charged or applicable to patrons of
the Parking Garage for spaces similarly situated therein. In the event the
Premises are increased or decreased during the Lease Term, the number of
Spaces available to Tenant shall likewise be increased or decreased so that
the aggregate number of spaces to which Tenant is entitled shall equal one
(1) Space for each 2,700 square feet of Rentable Area within the Premises.
Notwithstanding the foregoing, Landlord reserves the right, in its sole
discretion, to terminate Tenant's use of any or all of the Spaces located in
the 777 Clay Garage on thirty (30) days notice to Tenant.

     3.   TENANT'S FAILURE TO USE SPACES. In the event that Tenant (after the
Commencement Date and at any time during the Lease Term) fails to utilize all
or any of the Spaces, Landlord shall have no further obligation to make
available to Tenant the Spaces not utilized. The failure, for any reason, of
Landlord to provide or make available such Spaces to Tenant or the inability
of Tenant to utilize all or any portion of the Spaces shall under no
circumstances be deemed a default by Landlord under the Lease so as to permit
Tenant to terminate the Lease, in whole or in part.

    4.   RISK. All motor vehicles (including all contents thereof) shall be
parked in the Spaces at the sole risk of Tenant, its employees, agents,
invitees and licensees, it being expressly agreed and understood that
Landlord has no duty to insure any of said motor vehicles (including the
contents thereof), and that Landlord is not responsible for the protection
and security of such vehicles. Landlord shall have no liability whatsoever
for any property damage and/or personal injury which might occur as a result
of or in connection with the parking of said motor vehicles in any of the
Spaces, and Tenant hereby agrees to indemnify and hold Landlord harmless from
and against any and all costs, claims, expenses, and/or causes of action
which Landlord may incur in connection with or arising out of Tenant's use of
the Spaces pursuant to this Agreement.

     5.   NO BAILMENT. It is further agreed that this Parking Exhibit shall
not be deemed to create a bailment between the parties hereto, it being
expressly agreed and understood that the only relationship created between
Landlord and Tenant hereby is that of licensor and licensee, respectively.

     6.   RULES AND REGULATIONS. In its use of the Spaces, Tenant shall
follow all of the Rules and Regulations of the Building (attached to the
Lease as Exhibit "D") applicable thereto, any rules and regulations
promulgated by Landlord or the manager of the Parking Garage, as applicable,
as the same may be amended from time to time. Upon the occurrence of any
breach of such rules, failure to make parking rental payments due hereunder
or default by Tenant under the Lease, Landlord shall be entitled to terminate
this Parking Exhibit, in which event Tenant's right to utilize the Spaces
shall thereupon automatically cease.

     7.   ACCESS. Landlord shall be entitled to utilize whatever access
device Landlord deems necessary (including but not limited to the issuance of
parking stickers or access cards), to assure that only those persons who have
contracted to use spaces in the Parking Garage are using the parking spaces
therein. Landlord currently limits access to the Parking Garage through the
use of a parking entry card system, the cards for which shall be provided by
Landlord. These cards are different from and do not, without a specific
request from Tenant, entitle the holder thereof to an after-hours entry card
to the Building (pursuant to the terms of Paragraph 6(f). Landlord agrees to
provide to Tenant five (5) parking entry cards. Tenant further agrees to
surrender all parking entry cards in its possession upon the expiration or
earlier termination of this Lease. Landlord shall be entitled to cancel any
lost or stolen cards of which it becomes aware. Tenant shall promptly notify
Landlord of any lost or stolen cards. Tenant shall pay Landlord for each
additional card(s) or for each replacement card(s) for any card(s) lost by or
stolen from Tenant, in such amount as Landlord shall, from time to time
determine, the present charge for such lost or stolen cards being $10.00 per
card. Tenant acknowledges that the parking entry card may also be the same as
the master entry card used for access to the Building during other than
normal business hours, and to the extent the cards are the same, agrees that
the provisions of Paragraph 6(f) of the Lease shall also be applicable and in
the event of a conflict with the provisions of this Parking Exhibit, the
provisions of Paragraph 6(f) shall control. In the event Tenant, its agents
or employees wrongfully park in any of the Parking Garage's spaces, Landlord
shall be entitled and is hereby authorized to have any such vehicle towed
away, at Tenant's sole risk and expense, and Landlord is further authorized
to impose upon Tenant a penalty of $25.00 for each such occurrence. Tenant
hereby agrees to pay all amounts falling due hereunder upon demand therefor,
and the failure to pay any such amount shall additionally be deemed an event
of default hereunder and under the Lease, entitling Landlord to all of its
rights and remedies hereunder and thereunder.

                           OFFICE LEASE AGREEMENT BETWEEN

                                 AS LANDLORD AND
                               CALIBRE ENEROY, L.P.,
                                    AS TENANT

                              RIGHT OF FIRST REFUSAL


     This EXHIBIT "G" ("Refusal Exhibit") describes and specifies the right of
first refusal hereby granted by Landlord to Tenant with respect to the space
within the Building described below, which right of first refusal is being
granted upon the following terms and conditions:

     1.   DEFINED TERM. For purposes of this Refusal Exhibit, all terms
defined in the Lease will be utilized herein without further definition.
Terms specifically applicable to this Refusal Exhibit shall have the meanings
specified in this Refusal Exhibit and shall be delineated by initial capital
letters.

     2.   GRANT OF RIGHT OF FIRST REFUSAL. Landlord hereby grants to Tenant a
one time right of first refusal ("Refusal Right") with respect to
approximately 2,000 square feet of Rentable Area located contiguous to the
Premises which is described on SCHEDULE 1 attached hereto and incorporated
herein by reference for all purposes ("Refusal Space") during the period
commencing on the Commencement Date and ending as of the expiration or
termination date of this Lease. Notwithstanding the foregoing, the Refusal
Right shall not be applicable during any time when there is an uncured event
of default under the Lease. Notwithstanding anything to the contrary in the
foregoing, the Refusal Right shall be subject to the rights of any tenants
presently occupying space in the Building.

     3.   EXERCISE OF REFUSAL RIGHT. In the event that Refusal Space in the

Building becomes available, availability, for purposes hereof, to be at the
sole determination of Landlord, and Landlord receives a bona fide offer from
a third party to lease all or a part of the Refusal Space which Landlord
desires to accept, Landlord shall so notify Tenant and shall include in such
notice the rental rate for the subject Refusal Space, expense stop, term of
the proposed Lease (together with any renewal rights being granted), and any
lease concessions to be granted. Tenant shall have five (5) days from the
receipt of such notice to notify Landlord in writing of the exercise by
Tenant of Tenant's Refusal Right with respect to the subject Refusal Space,
which shall be on the same terms and with respect to the entire space
specified in Landlord's notice. In the event that Tenant fails to so notify
Landlord within such five (5) day period, Tenant shall be deemed to have
irrevocably waived its Refusal Right with respect to the subject Refusal
Space; and Landlord shall have the right to enter into a lease with any party
with respect to that Refusal Space. In the event that Tenant elects to
exercise its Refusal Right with respect to the subject Refusal Space and does
in fact exercise such Refusal Right in the manner and within the time period
specified herein, Landlord and Tenant shall, within thirty (30) days after
Tenant delivers to Landlord notice of its election, enter into a written
amendment modifying and supplementing the Lease and containing such other
terms and provisions as Landlord may deem appropriate. In the event that
Tenant fails to enter into said amendment within such thirty (30) day period,
Tenant shall be deemed to have irrevocably waived its Refusal Right with
respect to the subject Refusal Space; and Landlord shall have the right to
enter into a lease with any party with respect to that Refusal Space. Except
as may be specifically modified in such amendment and except with respect to
the rental, expense stop, lease term, and lease concessions applicable to the
subject Refusal Space, as herein specified, the terms and provisions of the
Lease shall, on the day of delivery of the subject Refusal Space to Tenant,
automatically apply and become applicable to the subject Refusal Space; and
the subject Refusal Space, as of the date of such delivery, shall
automatically and without the necessity of further documentation, become and
be deemed to be a part of the Premises. Effective as of the date of delivery
of the subject Refusal Space to Tenant, the Rentable Area within  the subject
Refusal Space shall be included within the determination of Tenant's prorate
of Basic Costs, as provided in EXHIBIT "C" to this Lease.

     4.   DELIVERY OF REFUSAL SPACE. Any Refusal Space shall be delivered to
Tenant vacant and unoccupied and "as is" without benefit of improvements
(except Shell Improvements, if any) unless the refusal notice specifies that
an allowance is to be granted for the improvement or refurbishment of the
subject Refusal Space, in which event Tenant will receive the allowance
specified in Landlord's notice. In the event that any improvements or
restoration work is to be incorporated into the Premises, the amendment shall
contain provisions reflecting the agreement of Landlord and Tenant with
respect thereto. Landlord shall use reasonable diligence to deliver the
subject Refusal Space on the date specified in Landlord's notice of its
availability, but in no event shall Landlord have any liability for the
failure to deliver the subject Refusal Space to Tenant on such date, nor
shall any such failure impair the validity of the Lease, extend the Lease
Term (except with respect to the subject Refusal Space, which shall be the
term specified in Landlord's notice irrespective of the Lease Term specified
in Paragraph 1 of the Lease), or impair any obligations of Tenant under the
Lease, it being understood that the Rent applicable to the subject Refusal
Space shall be abated until possession is delivered to Tenant in full
settlement of all claims that Tenant might otherwise have against Landlord by
reason of the failure to deliver possession of the subject Refusal Space to
Tenant.

     5.   TERMINATION OF REFUSAL RIGHT. The Refusal Right shall
automatically terminate upon (a) the termination of the Lease Term, whether by
Landlord upon the occurrence of an Event of Default or otherwise, (b) the
expiration of the time period specified in Paragraph 2 above, (c) the failure
of Tenant to exercise the Refusal Right with respect to any Refusal Space as
and within the time period specified in Paragraph 3 above, but only
with respect to the subject Refusal Space, and (d) upon the assignment,
subletting, or other transfer by Tenant, whether or not with the approval of
Landlord.

               (i)     The fees for Tenant's Architect and any consultants or
          engineers retained by or on behalf of Tenant or Tenant's Architect
          (including, but not limited to, the electrical, mechanical and
          structural engineers required to be retained under this paragraph)
          shall be paid by Tenant. Tenant shall also pay for any preliminary
          drawings by Landlord's Architect for review of the design drawings,
          the Plans and Specifications, and any revisions to such documents,
          and the fees and expenses of Landlord's Architect for inspection of
          the Work, as required by Landlord.

               (ii)    Tenant shall have the sole responsibility for
          compliance of the Plans and Specifications with all applicable
          statutes, codes, ordinances and other regulations, and the approval
          of the Plans and Specifications or calculations included therein by
          Landlord shall not constitute an indication, representation or
          certification by Landlord that such Plans and Specifications or
          calculations are in compliance with said statutes, codes,
          ordinances and other regulations. In instances where several sets
          of requirements must be met, the requirements of Landlord's
          insurance underwriter or the strictest applicable requirements
          shall apply where not prohibited by applicable codes.

              (iii)   Upon completion of the Initial Improvements, if so
          required by Landlord, Tenant shall deliver to Landlord an
          "as-built" set of Plans and Specifications for the Premises,
          together with such other information required by Landlord to place
          the information from the "as-built" Plans and Specifications on to
          Landlord's data base; the cost of providing the "as-built" Plans
          and Specifications and other information, together with Landlord's
          cost to place the information on to Landlord's date base, shall be
          born solely by Tenant.

     3.   PRICING. On or before the date which is ten (10) Working Days after
finalization of the Plans and Specifications, as evidenced by Landlord's
written approval thereof, Landlord shall notify Tenant in writing of the Cost
of the Work. The contract for the Work shall obligate the contractor to
purchase from Landlord all materials and supplies which are held in "stock"
by Landlord and which are required for the Work by the Plans and
Specifications. Within ten (10) Working Days after its receipt of Landlord's
written notice identifying the Cost of the Work, Tenant shall either approve
such Cost of the Work in writing or cause the Plans and Specifications to be
revised and resubmitted to Landlord for Approval. On or before the date which
is ten (10) Working Days from Landlord's receipt of such revised Plans and
Specifications, Landlord shall either approve the revised Plans and
Specifications and give to Tenant a revised Cost of the Work or give to
Tenant Landlord's comments on such revised Plans and Specifications. If for
any reason Landlord and Tenant have not agreed in writing upon final Plans
and Specifications and/or the Tenant has not approved in writing the Cost of
the Work on or before the date which is ten (10) Working Days from the date
hereof, then Landlord shall have the right to terminate the Lease and this
Workletter, without further obligation.

     4.   PAYMENTS. Tenant may use up to that part of the Allowance up to an
amount equal to one dollar ($1.00) per square foot of Rentable Area of the
Premises for the payment of fees and expenses payable by Tenant under the
terms of Paragraph 2(b)(1) of this Workletter. Tenant shall pay the aggregate
amount of Tenant's Costs to Landlord upon demand. Landlord shall determine
the percentage of the Cost of the Work which is allocable to Landlord and the
percentage of the Cost of the Work which is allocable to Tenant. Landlord
shall also revise its determination of such percentages based on any changes
in the Cost of the Work due to change orders affecting the Plans and
Specifications. Within ten (10) days after Tenant's receipt of an invoice
from Landlord which identifies that portion of the Cost of the Work to be
incurred, respectively, by Landlord and Tenant, Tenant shall pay to Landlord
the percentage of the Cost of the Work allocable to Tenant, as Tenant's
Costs, as determined by Landlord from time to time. Landlord's obligation for
payment with respect to the Work shall not exceed the aggregate amount of
Landlord's Costs; and after Landlord has paid Landlord's Costs, Tenant shall
thereafter pay all Cost of the Work as and when invoiced to Tenant by
Landlord, including, without limitation, any Change Costs. The amounts
payable to Landlord hereunder shall constitute Rent due pursuant to the Lease,
and failure to make any such payment when due shall constitute a default
under the Lease, entitling Landlord to exercise any or all of its remedies
hereunder, as well as all remedies otherwise available to Landlord. Any cost
savings achieved after completion of the Work shall be solely the property of
Landlord, not Tenant.

     5.  PERFORMANCE OF WORK AND DELAYS. Landlord shall cause the Contractor
to perform the Work in substantial accordance with the Plans and
Specifications. In that regard, Landlord shall perform as construction
manager for the construction of the Initial Improvements in accordance with
the Plans and Specifications. If a delay shall occur in the completion of the
Work by Landlord as the probable result of (i) any failure to furnish when
due Tenant's design drawings, Tenant's electrical, mechanical and/or
structural requirements, Tenant's Plans and Specifications or any revision to
any such documents, (ii) any change by Tenant in any of the Plans and
Specifications, (iii) any state of facts which gives rise to a change
referred to in the definition of Change Costs or any changes resulting in a
Change Cost, (iv) the fact that materials to be incorporated into the Work
which are non-Building Grade require a lead time (not due to Landlord default
or error) to obtain or construction time to perform, in excess of that
required for work which is Building Grade, as determined by Landlord, or (v)
any other act or omission of Tenant, its agents or employees, including any
violation of the provisions of the Lease or any delay in giving
authorizations or approvals pursuant to this Workletter, then any such delay
shall not justify any extension of the Commencement Date of the Lease.

     6.   CHANGE ORDERS. All changes and modifications in the Work from that
contemplated in the Plans and Specifications, whether or not such change or
modification gives rise to a Change Cost, must be evidenced by a written
Change Order executed by both Landlord and Tenant. In that regard, Tenant
shall submit to Landlord such information as Landlord shall require with
respect to any Change Order requested by Tenant. After receipt

EXHIBIT "C" TO SECOND AMENDMENT TO OFFICE LEASE AGREEMENT - Page 2

<PAGE>

of requested Change Order, together with such information as Landlord shall
require with respect thereto, Landlord shall return to Tenant either the
executed Change Order, which will evidence Landlord's approval thereof, or
the Plans and Specifications with respect thereto with Landlord's suggested
modification.

    7.   PUNCHLIST. Within thirty (30) days after the Commencement Date,
Tenant shall give Landlord written notice specifying any details of
construction, decoration or mechanical adjustment which remain to be
performed by Landlord with respect to any Work; and except for the details
contained in such written notice from Tenant, all obligations of Landlord in
regard to the Work shall be deemed to have been satisfied. Landlord shall
have the right to enter the Premises to complete any such unfinished details,
and entry by Landlord, its agents, servants, employees or contractors for
such purpose shall not relieve Tenant of any of its obligations under the
Lease or impose any liability on Landlord or its agents, servants, employees
or contractors.

    8.   WHOLE AGREEMENT; NO ORAL MODIFICATION. This Workletter embodies all
representations, warranties and agreements of Landlord and Tenant with
respect to the matter described herein, and this Workletter may not be
altered or modified except by an agreement in writing signed by the parties.

    9.   PARAGRAPH HEADINGS. The paragraph headings contained in this
Workletter are for convenient reference only and shall not in any way affect
the meaning or interpretation of such paragraphs.

    10.  NOTICES. All notices required or contemplated hereunder shall be
given to the parties in the manner specified for giving notices under the
Lease.

    11.  BINDING EFFECT. This Workletter shall be construed under the laws of
the State of Texas and shall be binding upon and shall inure to the benefit
of the parties hereto and their respective permitted successors and assigns.

    12.  CONFLICT. In the event of conflict between this Workletter and any
other exhibits or addenda to this Lease, this Workletter shall prevail.

     2.   PROCEDURE AND SCHEDULES FOR THE COMPLETION OF PLANS AND
SPECIFICATIONS.  The Plans and Specifications shall be completed in accordance
with the following procedure and time schedules:

          (a)  DESIGN DRAWINGS. Within ten (10) Working Days from execution
     of the Lease, Tenant shall submit to Landlord four (4) sets of prints of
     design drawings, specifying the intended design, character and finishing
     of the Initial Improvements within the Premises. Such package shall
     include separate drawings for signs in accordance with Landlord's sign
     criteria. The design drawings shall set forth the requirements of Tenant
     with respect to the installation of the Initial Improvements within the
     Premises, and such drawings shall include, without limiting their scope,
     a Tenant approved space plan, architectural design of the space,
     including office front, plans, elevations, sections, and renderings
     indicating materials, color selections and finishes.

               (i) After receipt of design drawings, Landlord shall return
          to Tenant one set of prints of design drawings with Landlord's
          suggested modifications and/or approval.

               (ii) If design drawings are returned to Tenant with comments,
          but not bearing approval of Landlord, the design drawings shall be
          immediately revised by Tenant and resubmitted to Landlord for approval
          within ten (10) Working Days of their receipt by Tenant. Unless such
          action is taken, Tenant will be deemed to have accepted and approved
          all of Landlord's comments on the design drawings.

         (b)  COMPLETION OF PLANS AND SPECIFICATIONS.  All Plans and
     Specifications shall be prepared in strict compliance with applicable
     Building standards and requirements as set forth in the Lease, this
     Workletter and otherwise, and shall also adhere to the design drawings
     approved by Landlord. In order to assure the compatibility of Tenant's
     electrical and mechanical systems and the compatibility of Tenant's
     structural requirements with the existing Building and in order to
     expedite the preparation of Tenant's electrical, mechanical and
     structural drawings, Tenant or Tenant's Architect shall deliver to
     Landlord's approval of design drawings, a detailed plan setting forth
     any and all electrical, mechanical and structural requirements, and
     Landlord's Architect shall retain, at Tenant's expense. Landlord's
     electrical, mechanical and structural engineers to prepare all necessary
     electrical, mechanical and structural construction drawings which shall
     be included as a part of the Plans and Specifications. All construction
     documents and calculations prepared by Tenant's Architect shall be
     submitted by Tenant, in the form of four (4) sets of blueline prints, to
     Landlord for approval within ten (10) Working Days after the date of
     receipt by Tenant of Landlord's approval of design drawings. If the
     Plans and Specifications are returned to Tenant with comments, but not
     bearing approval of Landlord, the Plans and Specifications shall be
     immediately revised by Tenant and resubmitted to Landlord for approval
     within ten (10) Working Days of their receipt by Tenant.

               (i) The fees for Tenant's Architect and any consultants
          or engineers retained by or on behalf of Tenant or Tenant's
          Architect (including, but not limited to, the electrical,
          mechanical and structural engineers required to be retained under
          this paragraph) shall be paid by Tenant. Tenant shall also pay for
          any preliminary drawings by Landlord's Architect for review of the
          design drawings, the Plans and Specifications, and any revisions to
          such documents, and the fees and expenses of Landlord's Architect
          for inspection of the Work, as required by Landlord.

               (ii) Tenant shall have the sole responsibility for
          compliance of the Plans and Specifications with all applicable
          statutes, codes, ordinances and other regulations, and the approval
          of the Plans and Specifications or calculations included therein by
          Landlord shall not constitute an indication, representation or
          certification by Landlord that such Plans and Specifications or
          calculations are in compliance with said statutes, codes, ordinances
          and other regulations. In instances where several sets of
          requirements must be met, the requirements of Landlord's insurance
          underwriter or the strictest applicable requirements shall apply
          where not prohibited by applicable codes.

               (iii) Upon completion of the Initial Improvements, if so
          required by Landlord, Tenant shall deliver to Landlord an
          "as-built" set of Plans and Specifications for the Premises,
          together with such other information required by Landlord to place
          the information from the "as-built" Plans and Specifications on to
          Landlord's data base; the cost of providing the "as-built" Plans
          and Specifications and other information, together with Landlord's
          cost to place the information on to Landlord's data base, shall be
          borne solely by Tenant.

     3.   PRICING. On or before the date which is ten (10) Working Days after
finalization of the Plans and Specifications, as evidenced by Landlord's
written approval thereof, Landlord shall notify Tenant in writing of the Cost
of the Work. The contract for the Work shall obligate the Contractor to
purchase from Landlord all materials and supplies which are held in "stock"
by Landlord and which are required for the Work by the Plans and
Specifications. Within ten (10) Working Days after its receipt of Landlord's
written notice identifying the Cost of the Work, Tenant shall either approve
such Cost of the Work in writing or cause the Plans and Specifications to be
revised and resubmitted to Landlord for Approval. On or before the date which
is ten (10) Working Days from Landlord's receipt of such revised Plans and
Specifications, Landlord shall either (i) notify Tenant that Landlord
approves the revised Plans and


EXHIBIT "C" TO THIRD AMENDMENT TO OFFICE LEASE - Page 2

<PAGE>

Specifications and give to Tenant a revised Cost of the Work or (ii) notify
Tenant of Landlord's comments on such revised Plans and Specifications. If
for any reason Landlord and Tenant have not agreed in writing upon final
Plans and Specifications and/or the Tenant  has not approved in writing the
Cost of the Work on or before the date which is ten (10) Working Days from
the date of Landlord's notice referenced in the prior sentence, then Landlord
shall have the right to terminate the Lease and this Workletter, without
further obligation.

     4.   PAYMENTS. Tenant may use that part of the Allowance up to an amount
equal to One Dollar ($1.00) per square foot of Rentable Area of the Premises
for the payment of fees and expenses payable by Tenant under the terms of
Paragraph 2(b)(i) of this Workletter. Tenant shall pay the aggregate amount
of Tenant's Costs to Landlord upon demand. Landlord shall determine the
percentage of the Cost of the Work which is allocable to Landlord and the
percentage of the Cost of the Work which is allocable to Tenant. Landlord
shall also revise its determination of such percentages based on any changes
in the Cost of the Work due to change orders affecting the Plans and
Specifications. With ten (10) days after Tenant's receipt of an invoice from
Landlord which identifies that portion of the Cost of the Work to be
incurred, respectively, by Landlord and Tenant, Tenant shall pay to Landlord
the percentage of the Cost of the Work allocable to Tenant, as Tenant's
Costs, as determined by Landlord from time to time. Landlord's obligation for
payment with respect to the Work shall not exceed the aggregate amount of
Landlord's Costs; and after Landlord has paid Landlord's Costs. Tenant shall
thereafter pay all Cost of the Work as and when invoiced to Tenant by
Landlord, including, without limitation, any Change Costs. The amounts
payable to Landlord hereunder shall constitute Rent due pursuant to the
Lease, and failure to make any such payment when due shall constitute a
default under the Lease, entitling Landlord to exercise any or all of its
remedies hereunder, as well as all remedies otherwise available to Landlord.
Any cost savings achieved after completion of the Work shall be solely the
property of Landlord, not Tenant.

     5.   PERFORMANCE OF WORK AND DELAYS. Landlord shall cause the Contractor
to perform the Work in substantial accordance with the Plans and
Specifications. In that regard, Landlord shall perform as construction
manager for the construction of the Initial Improvements in accordance with
the Plans and Specifications. If a delay shall occur in the completion of the
Work by Landlord as the probable result of (i) any failure to furnish when
due Tenant's design drawings, Tenant's electrical, mechanical and/or
structural requirements, Tenant's Plans and Specifications or any revision to
any such documents, (ii) any change by Tenant in any of the Plans and
Specifications, (iii) any state of facts which gives rise to a change
referred to in the definition of Change Costs or any changes resulting in a
Change Cost, (iv) the fact that materials to be incorporated into the Work
which are non-Building Grade require a lead time (not due to Landlord default
or error) to obtain or construction time to perform, in excess of that
required for Work which is Building Grade, as determined by Landlord, or (v)
any other act or omission of Tenant, its agents or employees, including any
violation of the provisions of the Lease or any delay in giving
authorizations or approvals pursuant to this Workletter, then any such delay
shall not justify any extension of the Commencement Date of the Lease.

     6.   CHANGE ORDERS. All changes and modifications in the Work from that
contemplated in the Plans and Specifications, whether or not such change or
modification gives rise to a Change Cost, must be evidenced by a written
Change Order executed by both Landlord and Tenant. In that regard, Tenant
shall submit to Landlord such information as Landlord shall require with
respect to any Change Order requested by Tenant. After receipt of requested
Change Order, together with such information as Landlord shall require with
respect thereto, Landlord shall return to Tenant either the executed Change
Order, which will evidence Landlord's approval thereof, or the Plans and
Specifications with respect thereto with Landlord's suggested modification.

     7.   PUNCHLIST. Within thirty (30) days after the Commencement Date,
Tenant shall give Landlord written notice specifying any details of
construction, decoration or mechanical adjustment which remain to be
performed by Landlord with respect to any Work; and except for the details
contained in such written notice from Tenant, all obligations of Landlord in
regard to the Work shall be deemed to have been satisfied. Landlord shall
have the right to enter the Premises to complete any such unfinished details,
and entry by Landlord, its agents, servants, employees or contractors for
such purpose shall not relieve Tenant of any of its obligations under the
Lease or impose any liability on Landlord or its agents, servants, employees
or contractors.

     8.   WHOLE AGREEMENT; NO ORAL MODIFICATION. This Workletter embodies all
representations, warranties and agreements of Landlord and Tenant with
respect to the matter described herein, and this Workletter may not be
altered or modified except by an agreement in writing signed by the parties.

     9.   PARAGRAPH HEADINGS. The paragraph headings contained in this
Workletter are for convenient reference only and shall not in any way affect
the meaning or interpretation of such paragraphs.

     10.  NOTICES. All notices required or contemplated hereunder shall be
given to the parties in the manner specified for giving notices under the
Lease.

     11.  BINDING EFFECT. This Workletter shall be construed under the laws
of the State of Texas and shall be binding upon and shall inure to the
benefit of the parties hereto and their respective permitted successors and
assigns.

     12.  CONFLICT. In the event of conflict between this Workletter and any
other exhibits or addenda to this Lease, this Workletter shall prevail.

                                        TO
                      THIRD AMENDMENT TO OFFICE LEASE BETWEEN
                        METROPOLITAN LIFE INSURANCE COMPANY
                    AND METROPOLITAN TOWER REALTY COMPANY, INC.,
                                 AS LANDLORD, AND
                             TEXSTAR PETROLEUM, L.L.C.,
                                     AS TENANT

                                      PARKING

     This EXHIBIT "D" ("Parking Exhibit") describes and specifies Tenant's
non-exclusive right to use seventeen (17) unreserved parking spaces and the
exclusive right to use zero (0) reserved parking space ("Space") located on
such levels inside one or more of the Building's parking garages as set forth
on SCHEDULE 1 attached to this Parking Exhibit and incorporated herein by
reference, all upon the terms and conditions set forth below.  The parking
garage beneath the Building shall be referred to as the "Building Garage."
The parking garage located at 1400 Louisiana shall be referred to as the
"1400 Louisiana Garage." The Building Garage and 1400 Louisiana Garage may be
hereinafter referred to individually and collectively as the "Parking Garage."

     1.   DEFINITIONS. The terms which are defined in the Lease shall have
the same meaning in this Parking Exhibit.

     2.   GRANT AND RENTAL FEE. Provided no event of default has occurred and
is continuing under the Lease, effective on the Second Expansion Space
Commencement Date. Landlord shall provide and Tenant shall be obligated to
contract and pay for the spaces during the Term at such monthly rates
(together with any applicable tax thereon) and subject to such terms,
conditions, and regulations as are, from time to time, promulgated by
Landlord or the manager of the Parking Garage, as applicable, and charged or
applicable to patrons of the Parking Garage for spaces similarly situated
therein. In the event the Leased Premises are decreased during the Term, the
number of Spaces available to Tenant shall likewise be decreased so that the
aggregate number of Spaces to which Tenant is entitled shall equal one (1)
Space in the Building Garage for each 11,000 square feet of Rentable Area
within the Leased Premises and one (1) Space in the 1400 Louisiana Garage for
each 1,650 square feet of Rentable Area within the Leased Premises.

     3.   RISK. All motor vehicles (including all contents thereof) shall be
parked in the Spaces at the sole risk of Tenant, its employees, agents,
invitees and licensees, it being expressly agreed and understood that
Landlord has no duty to insure any of said motor vehicles (including the
contents thereof), and that Landlord is not responsible for the protection
and security of such vehicles. Landlord shall have no liability whatsoever
for any property damage and/or personal injury which might occur as a result
of or in connection with the parking of said motor vehicles in any of the
Spaces, and Tenant hereby agrees to indemnify and hold Landlord harmless from
and against any and all costs, claims, expenses, and/or causes of action
which Landlord may incur in connection with or arising out of Tenant's use of
the Spaces pursuant to this Agreement.

     4.   NO BAILMENT. It is further agreed that this Parking Exhibit shall
not be deemed to create a bailment between the parties hereto, it being
expressly agreed and understood that the only relationship created between
Landlord and Tenant hereby is that of licensor and licensee, respectively.

     5.   RULES AND REGULATIONS. In its use of the Spaces, Tenant shall
follow all of the Rules and Regulations of the Building (attached to the
Lease as EXHIBIT "D") applicable thereto, any rules and regulations
promulgated by Landlord or the manager of the Parking Garage, as applicable,
as the same may be amended from time to time. Upon the occurrence of any
breach of such rules, failure to make parking rental payments due hereunder
or default by Tenant under the Lease, Landlord shall be entitled to terminate
this Parking Exhibit, in which event Tenant's right to utilize the Space
shall thereupon automatically cease.

     6.   ACCESS. Landlord shall be entitled to utilize whatever access
device Landlord deems necessary (including but not limited to the issuance of
parking stickers or access cards), to assure that only these persons who have
contracted to use spaces in the Parking Garage are using the parking space
therein. Landlord currently limits access to the Parking Garage through the
use of a parking entry card system, the cards for which shall be provided by
Landlord. These cards are different from and do not, without a specific
request from Tenant, entitle the holder thereof to an after-hours entry card
to the Building. Landlord agrees to provide to Tenant seventeen (17) parking
entry cards. Tenant further agrees to surrender all parking entry cards in
its possession upon the expiration or earlier termination of this Lease.
Landlord shall be entitled to cancel any lost or stolen cards of which it
becomes aware. Tenant shall promptly notify Landlord of any lost or stolen
cards. Tenant shall pay Landlord for each additional card(s) or for each
replacement card(s) for any card(s) lost by or stolen from Tenant, in such
amount as Landlord shall, from time to time determine, the present charge for
such lost or stolen cards being $10.00 per card. In the event Tenant, its
agents or employees wrongfully park in any of the Parking Garage's spaces,
Landlord shall be entitled and is hereby authorized to have any such vehicle
towed away, at Tenant's sole risk and expense, and Landlord is further
authorized to impose upon Tenant a penalty of $25.00 for each such
occurrence. Tenant hereby agrees to pay all amounts falling due hereunder
upon demand therefor, and the failure to pay any such amount shall
additionally be deemed an event of default hereunder and under the Lease,
entitling Landlord to all of its rights and remedies hereunder and thereunder.

initial conversion price of Cdn. $0.35 (the "Preferred Conversion Price"), as
compared to a conversion price of Cdn. $1.40 for the Notes (the "Note

HIGH DEGREE OF RISK. AN INVESTMENT IN THE PREFERRED STOCK SHOULD BE

The Preferred Stock will be offered to a limited number of investors who are
not Canadian residents or "U.S. persons" (as defined in Regulation S under
the Securities Act) in reliance upon an exemption from the registration
requirements of the Securities Act pursuant to Regulation S under the
Securities Act and exemptions from the registration and prospectus
requirements of applicable securities legislation in Canada. The Preferred
Stock will have restrictions on its resale. Regulation S, the safe harbor
pursuant to which the Preferred Stock is being offered, prohibits the
Preferred Stock from coming into the hands of U.S. persons for a period of
one year (unless registered under the Securities Act or sold pursuant to an
exemption from such registration requirements), deems the Preferred Stock
"restricted securities" as defined in Rule 144 of the Securities Act, and
imposes legend requirements. Hedging transactions involving the Preferred
Stock may not be conducted unless in compliance with the Securities Act.
Certain provisions have been included in the terms and conditions of the
Preferred Stock in order to assure compliance with Regulation S. The Company
may, in its discretion, revise the selling restrictions on the Preferred
Stock if the Securities and Exchange Commission (the "Commission") or any
other regulatory authority should, subsequent to the date of this Offering
Circular, amend or give advice or interpretations respecting the selling
restrictions applicable to the Preferred Stock. If the Company so revises the
selling restrictions, it will give notice to the holders of the Preferred
Stock addressed to each holder of record at his or her address appearing on
the books of the Company and it shall cause a copy of such notice (or a
reasonable summary thereof) to be published in THE FINANCIAL TIMES (EUROPEAN
EDITION) of London, England.

The Preferred Stock will bear a legend indicating that it has not been
qualified for distribution in British Columbia or in any other Province of
Canada and may not be offered, sold, transferred, pledged, converted or
otherwise disposed of in British Columbia or in any other Province of Canada

Province of Canada except in accordance with applicable resale restrictions

                                   be paid free of withholding taxes. The

                                   Capital."

CONVERSION:                        Through March 31, 2000, the Preferred Stock

                                   Conversion Price") equal to Cdn. $0.35. If
                                   on March 31, 2000, the average of the Market
                                   Prices during the preceding 20 consecutive
                                   Stock Exchange Business Days is lower than
                                   the Preferred Conversion Price, then the
                                   Preferred Conversion Price will be adjusted
                                   downward to such average price. The Company
                                   will use its best efforts to ensure that

                                   the Preferred Stock and any Common Stock
                                   issuable as dividends or on conversion are
                                   Freely Tradable. If such securities are not
                                   Freely Tradable within that time period, the
                                   Preferred Conversion Price shall be reduced
                                   thereafter by 5% for each six month period
                                   or portion thereof until such securities are
                                   Freely Tradable. Upon the conversion of any
                                   Preferred Stock, payment will be made by the
                                   Company within 60 days following conversion
                                   for dividends accrued during the period from
                                   the most recent dividend payment date to the
                                   conversion date.

REQUIRED CONVERSION:               The Company may cause all of the Preferred
                                   Stock to be converted into Common Stock at
                                   the then Preferred Conversion Price at any
                                   time after March 31, 2000, if the average

HOW TO TENDER:                     Tendering holders of Notes must complete and

                                   Letter of Transmittal and any other required
                                   documents to the Exchange Agent and tender
                                   such Notes pursuant to the procedures for
                                   guaranteed delivery or book-entry transfer,
                                   and if choosing option 1 and the holder is a
                                   member of the ICSD system, instruct Cedel or
                                   Euroclear to debit such holder's ICSD
                                   account by the required amount on the
                                   instructions of the Exchange Agent and
                                   thereafter deliver such amount to the
                                   Exchange Agent's account, or if the holder
                                   of Notes is not a member of the ICSD system,
                                   then such holder must contact the Agent to

                                   not recommended due to the fact that the
                                   Notes are in bearer form. Confirmation of a
                                   book-entry transfer of such Notes to the
                                   Exchange Agent's account at the Book-Entry

HOW TO TENDER

         Tendering holders of Notes must complete and sign a Letter of
Transmittal or a facsimile thereof (all references in this Offering Circular
to the Letter of Transmittal shall be deemed to include a facsimile thereof),
forward the Letter of Transmittal and any other required documents to the
Exchange Agent at the address set forth in the Letter of Transmittal and
tender such Notes pursuant to the procedures for guaranteed delivery or
book-entry transfer. Physical delivery of Notes is not recommended due to the
fact that the Notes are in bearer form. Confirmation of a book-entry transfer
of such Notes to the Exchange Agent's account at the Book-Entry Facility (as
defined below) will effectuate delivery of the Notes in a timely fashion. If
electing Option 1 and if the holder of Notes has an ICSD account, then such
holder shall instruct Cedel or Euroclear to debit such holder's ICSD account
by the required cash payment on the instructions of the Exchange Agent and
thereafter deliver such amount to the Exchange Agent's account or if the
holder of Notes is not a member of the ICSD system, then such holder must
contact the Agent to arrange for payment. Questions regarding how to tender
and requests for information should be directed to the Company.

         The Exchange Agent will establish an account with respect to the
Notes at Euroclear and Cedelbank (each individually, a "Book-Entry Facility")
as soon as practicable after the date of this Offering Circular, and any
financial institution which is a participant in the Book-Entry Facility may
make book-entry delivery of the Notes by causing the Book-Entry Facility to
transfer such Notes into the Exchange Agent's account in accordance with the
Book-Entry Facility's procedure for such transfer. Although delivery of Notes
may be effected through book-entry transfer into the Exchange Agent's account
at the Book-Entry Facility, the Letter of Transmittal, any required cash
payment (either through the ICSD account system or in readily available
funds) and any other required documents, must in any case be transmitted to
and received by the appropriate party on or prior to the Expiration Date.
Delivery of documents to the Book-Entry Facility does not constitute delivery
to the Exchange Agent. All references in this Offering Circular to deposit or
delivery of Notes shall be deemed to include the Book-Entry Facility's
book-entry delivery method.

         THE METHOD OF DELIVERY OF NOTES AND ALL OTHER DOCUMENTS, INCLUDING
DELIVERY THROUGH THE BOOK-ENTRY FACILITY, IS AT THE ELECTION AND RISK OF THE
HOLDER OF NOTES.

         The Notes will be offered for exchange in minimum denominations of
$5,000 each and integral multiples thereof. Tendering holders of Notes may
tender less than all of the Notes represented by the certificates they hold
provided they appropriately indicate this fact on the Letter of Transmittal
accompanying the tendered Note certificates.

         With respect to tenders of Notes, the Company reserves full
discretion to determine whether the documentation is complete and generally
to determine all questions as to tenders, including the date of receipt of a
tender, the propriety of execution of any document, and other questions as to
the validity, form, eligibility or acceptability of any tender. The Company
reserves the right to reject any tender not in proper form or otherwise not
valid or the acceptance for exchange of which may, in the reasonable opinion
of the Company's counsel, be unlawful or to waive any irregularities or
conditions, and the Company's interpretation of the terms and conditions of
the Offering (including the instructions on the Letter of Transmittal) will
be final. The Company shall not be obligated to give notice of any defects or
irregularities in tenders and shall not incur any liability for failure to
give any such notice. Notes shall not be deemed to have been duly or validly
tendered unless and until all defects and irregularities have been cured or
waived.

TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL

         The Letter of Transmittal contains, among other things, certain
terms and conditions, which are summarised below and are part of the Offering.

         On or prior to the Expiration Date, (i) a beneficial owner of the
Notes or an Agent Member Bank ("Agent Member Bank") of the Euroclear System
or Cedelbank must have effectuated the transaction on behalf of the tendering
beneficial owner(s) and (ii) the Letter of Transmittal, with other required
documents, must be transmitted to and received by the Exchange Agent at the
address as set forth in the Letter of Transmittal. If choosing Option 1 and a
member of the ICSD system, the holder must instruct Cedel or Euroclear to
debit such holder's ICSD account by the required amount on the instructions
of the Exchange Agent and thereafter deliver such amount to the Exchange
Agent's account, or if the holder of Notes is not a member of the ICSD
system, then such holder must contact the Agent to arrange for the delivery
of the required cash payment. The party tendering the Notes for exchange on
behalf of the beneficial owner(s) (the "Holder") by execution of the Letter
of Transmittal sells, assigns and transfers the Notes to the Exchange Agent
and irrevocably constitutes and appoints the Exchange Agent as the Holder's
agent and attorney-in-fact to cause the Notes to be transferred and
exchanged. The Holder warrants that it has full power and authority to
tender, exchange, sell, assign and transfer the Notes and to acquire shares
of Preferred Stock issuable upon the exchange of such tendered Notes and the
delivery of any required cash payment, that the Company will acquire good and
unencumbered title to the tendered Notes, free and clear of all liens,
restrictions, charges and encumbrances, and that the Notes tendered for
exchange are not subject to any adverse claims when accepted by the Company.
The Holder also warrants that it will, upon request, execute and deliver any
additional documents deemed by the Company to be necessary or desirable to
complete the exchange, sale, assignment and transfer of the tendered Notes.
All authority conferred or agreed to be conferred in the Letter of
Transmittal by the Holder will survive the death or incapacity of the Holder
and any obligation of the Holder shall be binding upon the heirs, personal
representatives, successors and assigns of such Holder.

         All questions as to the validity, form, eligibility (including time
of receipt) and acceptability of any tender will be determined by the
Company, in its reasonable discretion, and such determination will be final
and binding. Unless waived by the Company, irregularities and defects must be
cured by the Expiration Date. The Company will pay all stock transfer taxes
applicable to the transfer and exchange of Notes tendered.

WITHDRAWAL RIGHTS

         All tenders of Notes may be withdrawn at any time prior to the
Expiration Date unless otherwise agreed by a Holder. To be effective, a
notice of withdrawal must be timely received by the Exchange Agent at the
address as set forth in the Letter of Transmittal. Any notice of withdrawal
must specify the person named in the Letter of Transmittal as having tendered
the Notes, the number of Notes to be withdrawn and the name of the holder of
such Notes. If the Notes have been delivered pursuant to the book-entry
procedures set forth above under "The Offering - How to Tender," any notice
of withdrawal must specify the name and number of the participant's account
at the Book-Entry Facility to be credited with the withdrawn Notes. The
Exchange Agent will confirm to each Noteholder in writing as to any properly
withdrawn Notes as soon as practicable following receipt of notice of
withdrawal. All questions as to the validity, including time of receipt, of
notices of withdrawals will be determined in the Company's reasonable
judgement.

                                      18

            CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

         This Offering Circular includes "forward-looking statements." All
statements other than statements of historical facts included in this
Offering Circular, including without limitation statements under "Summary,"
"Risk Factors," "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and "Business and Properties" regarding planned
capital expenditures, the availability of capital resources to fund capital
expenditures, estimates of proved reserves, the number of anticipated wells
to be drilled in the future, the Company's financial position, business
strategy and other plans and objectives for future operations, are
forward-looking statements. Although the Company believes that the
expectations reflected in such forward-looking statements are reasonable, it
can give no assurance that such expectations will prove to be correct. There
are numerous uncertainties inherent in estimating quantities of proved oil
and natural gas reserves and in projecting future rates of production and
timing of development expenditures, including many factors beyond the
Company's control. Reserve engineering is a subjective process of estimating
underground accumulations of oil and natural gas that cannot be measured in
an exact way, and the accuracy of any reserve estimate is a function of the
quality of available data and of engineering and geological interpretation
and judgement. As a result, estimates made by different engineers often vary
from one another. In addition, results of drilling, testing and production
after the date of an estimate may justify revisions of such estimate and such
revisions, if significant, would change the schedule of any further
production and development drilling. Accordingly, reserve estimates are
generally different from quantities of oil and natural gas that ultimately
are recovered. Additional important factors that could cause actual results
to differ materially from the Company's expectations are disclosed elsewhere
in this Offering Circular. All subsequent written and oral forward-looking
statements attributable to the Company or persons acting on its behalf are
expressly qualified in their entirety by such factors.

                                RISK FACTORS

LIMITED OPERATING HISTORY; HISTORY OF LOSSES; ACCUMULATED LOSSES AND WORKING
CAPITAL DEFICITS

         The Company commenced operations in 1991 and acquired a substantial
portion of its operating assets through the acquisition of Texstar in October
1996. Potential purchasers, therefore, have limited historical financial and
operating information upon which to base an evaluation of the Company's
performance and whether to invest in the Company's securities. The Company
has incurred substantial operating and net losses to date. The following
table reflects total net losses and net losses per share of Common Stock for
the periods indicated:

<TABLE>

<PAGE>

         The Company will continue to require substantial expenditures to
develop and expand its business. The Company's future financial results will
depend primarily on the following:

         -        its ability to economically locate hydrocarbons in
                  commercial quantities;

         -        its ability to reduce drilling risks and costs through 3-D
                  seismic data and CAEX technologies in selecting site and
                  depth of wells;

         -        its ability to secure adequate financial resources to fund
                  activities; and

         -        externally, on oil and gas prices.

         There can be no assurance that the Company will achieve or sustain
profitability or positive cash flows from operating activities in the future.
See "Risk Factors - Substantial Capital Requirements" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

SUBSTANTIAL CAPITAL REQUIREMENTS

         The Company has experienced and expects to continue to experience
substantial working capital needs. Its ongoing capital requirements consist
primarily of the following items:

         -        funding the 1999 capital and exploration budget;

         -        payment for the recently completed 3-D survey at Old Ocean
                  Field in installments totaling approximately $6,700,000
                  beginning in June of 1999. The first scheduled payment is
                  past due. The Company has reached an oral agreement with
                  respect to payment terms described below under "Impending
                  Maturity Dates".

         -        payment of EnCap Credit Facility, the BOCP Credit Facility
                  and the Old Ocean Loan, all due June 30, 1999 in the
                  principal amounts of $12.0 million, $6.0 million and $2.2
                  million, plus accrued interest, respectively. The Company is
                  negotiating a production financing facility to fund the
                  repayment of the first two facilities and is negotiating to
                  use Preferred Stock to repay all but $100,000 of the Old
                  Ocean Loan;

         -        potential repurchase of the Shell Production Payment;

         -        payment of certain trade payables of which $11,360,000 is
                  past due as of June 10, 1999;

         -        payment of preferred dividends not otherwise paid in Common
                  Stock; and

         -        payment of interest on the Convertible Debentures and bank
                  obligations.

         The Company's 1999 capital and exploration budget is $11.3 million
(excluding capitalized interest and overhead). The Company plans to finance
anticipated ongoing expenses and its 1999 capital and exploration budget with
funds generated from the following sources:

         -        available cash and cash investments;

         -        cash provided by operation activities;

         -        capital the Company believes it can raise through an
                  increase in the Shell Production Payment or the sale of a
                  term production payment, and sale of equity;

         -        non-core asset sales and sales of excess interests in core
                  assets;

         -        a $4.0 million capital infusion from an affiliate of EnCap;
                  and

         -        capital raised in connection with the Offering.

         No assurance can be given as to the availability or terms of
additional financing that may be required. If such capital resources are not
available, the Company may be required to curtail its drilling, development
and other operations; may not be able to participate in operations proposed
by others with an interest in its properties and be subjected to applicable
non-consent penalties; and may not be able to meet certain of its existing
contractual

                                      21
<PAGE>

obligations, which as to any of the foregoing could have a material adverse
effect on the Company and its financial condition.

IMPENDING MATURITY DATES

         The Company's EnCap, BOCP and Old Ocean Credit Facilities will come
due on June 30, 1999. The Company anticipates that as to the indebtedness
reflected by the Old Ocean Loan, that all lenders, other than affiliates of
EnCap that are owed $100,000, will elect to convert their respective
indebtedness and the mineral interests obtained in connection with the Old
Ocean Loan into Preferred Stock. The Company anticipates that it will pay off
the $100,000 owed to affiliates of EnCap under the Old Ocean Loan and the
indebtedness reflected by the EnCap Credit Facility and the BOCP Credit
Facility with funds obtained in connection with the Offering and new funds
anticipated to be received in connection with either an increase of the Shell
Production Payment or through funds received in connection with a new
production payment arrangement with a new lender. The Company is currently
engaged in negotiations as to both financing options, but does not have a
binding agreement with respect to either option. There can be no assurance
that either financing option will be consummated. The Company anticipates
that any such financing will not close until after June 30, 1999. The Company
currently does not have an extension of the maturity dates with respect to
the EnCap and BOCP Credit Facilities, but the lenders thereunder have in the
past granted maturity date extensions, and the Company believes that EnCap
Energy and BOCP will continue to extend the maturity dates to provide the
Company with sufficient time to obtain the new financings. If the maturity
dates under the EnCap and BOCP Credit Facilities are not extended or the
Company is unable to obtain sufficient new financings to pay off the EnCap
Credit Facility and the BOCP Credit Facility, then the Company will be in
default under the applicable Credit Facility and the applicable lenders will
have the right to seek immediate repayment of the entire indebtedness due
thereunder and enforce its other remedies, which include the right to
foreclose on substantially all of the properties of the Company. Such a
default will also cause defaults under other material contracts to which the
Company and its subsidiaries are parties. Any of the foregoing actions could
cause the Company to cease operations.

         On June 10, 1999, the Company was obligated to pay one-half of the
$6.7 million cost of acquiring certain seismic materials relating to the Old
Ocean Prospect and was obligated to pay the remaining amounts 60 days after
delivery of the processed data. The Company failed to make the payment due on
June 10, 1999. The Company has, however, reached a verbal arrangement for the
extension of the date of the first required payment until the end of the week
of June 14, 1999, at which time the Company has agreed to pay a portion, but
not all, of the first payment. The verbal agreement requires that the balance
of the initial payment be paid by the end of July rather than the currently
scheduled payment date of 60 days following delivery of the processed data.
Funds for the payment are anticipated to come from a sale by the Company of
approximately 37.5% of its interest in the Old Ocean Prospect. The Company
currently is in negotiation for the sale of such interest, but has not
entered into a definitive agreement with any party with respect to the sale.
Although the Company believes the sale will be consummated in time for the
Company to meet its payment obligations, there can be no assurance that the
sale of the interest will be consummated by such time or at all. If the
Company is unable to complete such transaction and is unable to satisfy its
payment obligations by some other means, the Company will be in default with
respect to its obligations to the company that has completed the seismic
survey and with the other owner of an interest in the Old Ocean Prospect.
Such defaults would subject the Company to the possibility of losing its
rights in the seismic materials and in a substantial portion of its rights in
the Old Ocean Prospect. Such defaults will also cause defaults under other
material contracts to which the Company and its subsidiaries are parties. Any
of the foregoing actions would have a material adverse effect on the Company
and its financial condition.

TRADE PAYABLES

         At June 10, 1999, the Company had outstanding approximately
$12,980,000 of accounts payable to industry partners and trade creditors.
Approximately $11,360,000 of this amount is past due. The Company intends to
request the holders of such accounts payable to accept payment over an
extended time and to accept a discount on the total payment due or accept a
further delay in the payment of such payables and receive payment in full.
There can be no assurance that any of the Company's creditors will accept the
proposed discounts or other payment terms. The Company anticipates funding
these payment obligations by using the proceeds to be received from either
the increase in the Shell Production Payment, the new production payment that
the Company is attempting to arrange, sale of assets and production revenue.
If a creditor is unwilling to participate in any such arrangement and the
Company does not have sufficient funds to pay such creditor, then a creditor
may declare the Company in default

                                      22
<PAGE>

and pursue its available remedies against the Company. Those remedies could
include, under certain circumstances, placing the Company into involuntary
bankruptcy.

ABILITY TO CONTINUE AS A GOING CONCERN

         The report of the Company's independent public accountants in the
Company's financial statements includes an explanatory paragraph that states
that the Company's ability to continue as a going concern is in question.
Note 18 to the Company's consolidated financial statements states that the
financial statements were prepared assuming that the Company is able to
continue as a going concern assuming certain events, such as refinancing of
the Company's indebtedness and the anticipated success of certain of the
Company's oil and gas wells will occur. There can be no assurance that the
events described in the going concern note will occur, and if they do not
occur, the Company may be unable to continue as a going concern.

VOLATILITY OF OIL AND GAS MARKETS

         MARKET PRICES ARE VOLATILE

         The Company's profitability and cash flow depend greatly on the
market price of oil and natural gas. Prices for oil and natural gas are
subject to wide fluctuations in response to relatively minor changes in
supply and demand, market uncertainty and a variety of additional factors
that it cannot control. These factors include:

         -        the level of consumer product demand;

         -        weather conditions;

         -        domestic and foreign governmental regulations;

         -        the price and availability of alternative fuels;

         -        political conditions in the Middle East;

         -        the foreign supply of oil and natural gas;

         -        the price of oil and gas imports; and

         -        overall economic conditions.

         The Company's ability to maintain or increase its borrowing capacity
and to obtain additional capital on attractive terms, or not at all, is also
substantially dependent upon oil and gas prices. Compared to 1997, the
average prices for the Company's production have generally declined.
Continued low prices could seriously effect the Company's cash flow,
financial condition and access to additional capital.

         HEDGING TRANSACTIONS MAY MITIGATE FLUCTUATION IN PRICES

         Substantially all of the Company's sales of oil and natural gas are
made in the spot market or pursuant to contracts based on spot market prices.
To reduce price risk, the Company sometimes executes contracts on a portion
of its production to hedge against market price changes. Hedging transactions
are intended to limit the negative effect of future price declines, but could
also limit the Company's participation in significant price increases for the
covered period. The Company cannot be certain that hedging transactions will
reduce the effect of any substantial declines in oil and natural gas prices.
As of December 31, 1998, the Company was not a party to any natural gas
futures contracts, crude oil swap agreements or other commodity hedging
agreement; however, the Company has agreed to backstop the limited gas hedges
entered into by Shell Capital covering gas dedicated to its term production
payment in the event such gas volumes delivered to Shell Capital are less
than the amounts hedged. In March, the Company entered into a forward sale of
ten contracts for delivery in May 1999 and twelve contracts for delivery in
June, July and August, of its anticipated gas production at an average price
of $2.07/MMBTU. Each contract equates to 10,000 million BTU of gas.

                                      23
<PAGE>

UNCERTAINTY OF ESTIMATES OF OIL AND GAS RESERVES

         There is substantial uncertainty in estimating quantities of proved
reserves and projecting future production rates and the timing of development
expenditures. No one can measure underground accumulations of oil and natural
gas in an exact way. Accordingly, oil and gas reserve engineering requires
subjective estimations of those accumulations. Estimates of other engineers
might differ widely from those of the Company's internal engineers as well as
Lenser & Associates, the Company's independent engineers. Accuracy of reserve
estimates depends on the quality of available data and on engineering and
geological interpretation and judgment. Lenser & Associates may make material
changes to reserve estimates based on the results of actual drilling, testing
and production. As a result, the Company's reserve estimates often differ
from the quantities of oil and gas it ultimately recovers. Also, the Company
makes certain assumptions regarding future oil and gas prices, production
levels, and operating and development costs that may prove incorrect. Any
significant variance from these assumptions could greatly affect the
Company's estimates of reserves and future net revenues.

EXPLORATION RISKS; RELIANCE ON 3-D SEISMIC DATA AND CAEX TECHNOLOGY

         The Company's strategy is to enhance the value of its prospects
through the use of 3-D seismic data and CAEX technology with emphasis on
direct hydrocarbon detection technologies. These technologies create computer
generated 3-D displays of subsurface geological formations that enable the
Company's explorationists to detect seismic anomalies and structural features
that are not apparent in 2-D seismic surveys. These technologies, however,
require greater pre-drilling expenditures than traditional drilling
strategies. Even when fully used and properly interpreted, 3-D seismic data
and CAEX visualization techniques only assist geo-scientists in identifying
subsurface structures and hydrocarbon indicators, and do not conclusively
allow the interpreter to know if hydrocarbons will in fact be present and
recoverable in such structures.

OPERATING AND UNINSURED RISKS

         The Company must continually acquire or explore for and develop new
oil and natural gas reserves to replace those produced and sold. The
Company's hydrocarbon reserves and revenues will decline if it is not
successful in its drilling, acquisition or exploration activities. The
Company cannot be certain that its exploration and development projects will
result in significant additional reserves or that the Company will have
success drilling productive wells at economically viable costs. Casualty risk
and other operating risks could cause reserves and revenues to decline.

         CASUALTY RISKS

         The Company's operations are subject to the following inherent
casualty risks:

         -        fires;

         -        explosions and blow-outs;

         -        abnormally pressured formation;

         -        uncontrollable flows of oil, natural gas or well fluids;

         -        pollution and other environmental risks; and

         -        pipe failure.

         The Company could suffer substantial financial losses due to any of
the following:

         -        injury or loss of life;

         -        severe damage to and destruction of property and equipment;

         -        pollution and other environmental damage;

         -        regulatory investigations and penalties; and

         -        suspension of operations.

                                       24

<PAGE>

         UNINSURED RISKS

         As is customary in the industry, the Company maintains insurance
against some, but not all, casualty risks incidental to its business.

         OTHER OPERATING RISKS

         Numerous risks affect the Company's drilling activities, including
the risk of drilling non-productive wells or dry holes. The cost of drilling,
completing and operating wells and of installing production facilities and
pipelines is often uncertain. Also, the Company's drilling operations could
diminish or cease because of any of the following:

         -        title problems;

         -        compliance with governmental regulations;

         -        shortages or delays in the delivery or availability of
                  drilling rigs and other equipment; and

         -        weather conditions.

         Moreover, effective marketing of the Company's natural gas
production depends on a number of factors such as the following:

         -        existing market supply of and demand for natural gas;

         -        the proximity of its reserves to pipelines;

         -        the available capacity of such pipelines; and

         -        government regulations.

         The marketing of oil and gas production similarly depends on the
availability of pipelines and other transportation, processing and refining
facilities, and the existence of adequate markets. As a result, even if
hydrocarbons are discovered in commercial quantities, a substantial period of
time may elapse before commercial production commences. If pipeline
facilities in an area are insufficient, the Company may have to wait for
construction or expansion of pipeline capacity before the Company can market
production from the area.

GOVERNMENTAL REGULATIONS AND ENVIRONMENTAL RISKS

         LEGAL LIMITATIONS

         The Company is subject to various United States federal, state and
local laws and regulations on taxation, exploration and development, and
environmental and safety matters. Many laws and regulations require drilling
permits and govern the spacing of wells, the prevention of waste, rates of
production and other matters. These statutes and regulations, and any others
that are passed by the jurisdictions where the Company has production, could
limit the total number of wells drilled or the total allowable production
from successful wells, which could limit revenues. Currently, the Company has
not curtailed production on any of its oil and gas wells.

         ENVIRONMENTAL LIABILITIES

         The Company could incur liability to the government or third parties
for any unlawful discharge of oil, gas or other pollutants into the air, soil
or water, including responsibility for remedial costs. The Company could
potentially discharge oil or natural gas into the environment in any of the
following ways:

         -        from a well or drilling equipment at a drill site;

         -        leakage from storage tanks, pipelines or other gathering and
                  transportation facilities;

         -        damage to oil or natural gas wells resulting from accidents
                  during normal operations; or

                                       25

<PAGE>

         -        blow-outs or explosions.

         Environmental discharges may move through soil to water supplies or
adjoining properties giving rise to additional liabilities. Some laws and
regulations could impose liability for failure to notify the proper
authorities of a discharge and other failures to comply with those laws.
Environmental laws may also affect the costs of the Company's acquisitions of
properties. The Company does not believe that its environmental risks are
materially different from those of comparable companies in the oil and gas
industry. However, the Company cannot be certain that environmental laws will
not, in the future, result in decreased production, substantially increased
costs of operations or other adverse effects to its operations and financial
condition. Pollution and similar environmental risks generally are not fully
insurable.

COMPETITION

         The oil and gas industry is highly competitive. The Company competes
with major oil and gas companies, other independent oil and gas concerns, and
individual producers and operators. Many of these competitors have financial
and other resources substantially greater than those available to the
Company. Moreover, the oil and gas industry competes with other industries in
supplying the energy and fuel needs of industrial, commercial and other
consumers. Increased competition causing over supply and depressed prices
could greatly affect the Company's operations revenues.

DEPENDENCE ON THE K.S. BYRD 31-1 #1 WELL AND HOWELL #1 WELL

         For the first quarter of 1999, revenue from the K.S. Byrd 31-1#1
well totaled approximately $640,800, 47% of the Company's total revenue, on
net production of 4,290 MCFGED. The K.S. Byrd 31-1#1 well accounted for
approximately $2.4 million of the Company's revenue for the year ended
December 31, 1998, 49% of total revenue, on net production of 3,226 MCFGED.
After dedication of certain volumes to the Shell Production Payment or a
replacement production payment, the K.S. Byrd 31-1 #1 will continue to be a
major contributor to the Company's net production. Subsequent to year-end
1998, the Company put the Howell #1 on production at a high rate of gas flow.
The Howell well is expected to contribute greater net production than the
Byrd, and thus, should become the largest production source for the Company.

CONFLICTS OF INTEREST WITH RESPECT TO CERTAIN TRANSACTIONS

         The Company has engaged in acquisitions, financings, and other
transactions with entities that are owned in part by certain of the Company's
officers, directors and affiliates. The Company believes that these
transactions were fair to the Company; however, the transactions did not
result from arms length negotiations. See "Interests in Management and Others
in Material Transactions".

CONTROL BY EXISTING MANAGEMENT AND STOCKHOLDERS

         The Chairman and Chief Executive Officer, Prentis B. Tomlinson, Jr.
and his wife Heather Tomlinson, beneficially own approximately 35.8% and
6.6%, respectively, of the Company's outstanding Common Stock. Mr. and Mrs.
Tomlinson are able to exercise significant influence over the Company's
affairs, including election of the board of directors and other matters
submitted to a vote of the stockholders. Assuming full conversion of all
Convertible Debentures and the exercise of all warrants, Mr. and Mrs.
Tomlinson will beneficially own approximately 6% and 1.1%, respectively, of
the then outstanding shares of Common Stock.

SHARES ELIGIBLE FOR FUTURE SALE

         As of March 31, 1999, the Company had 33,727,724 shares of Common
Stock outstanding. Of the outstanding Common Stock, 16,430,717 shares are
owned by affiliates, as defined in regulations under the Securities Act, and
will be considered "Restricted Stock" within the meaning of Rule 144 under
the Securities Act. Common Stock held by affiliates may not be sold in the
United States in the absence of registration under the Securities Act, unless
an exemption from registration is available. The remaining outstanding Common
Stock is freely transferable in the United States by persons other than
affiliates without restriction or further registration under the Securities
Act. Although the Company cannot predict the timing or amount of future sales
of Common Stock, if any, by selling shareholders or affiliates of the Company
or the effect that the availability of such Common Stock for sale

                                       26

<PAGE>

will have on the market price from time to time, sales of substantial amounts
of Common Stock could adversely affect the market price of the Common Stock.
See "Principal Shareholders" and "Description of Share Capital". In addition
to the Common Stock described above, 7,311,578 shares of Common Stock are
reserved for issuance or are issuable upon the exercise of outstanding
warrants, options and other convertible securities. Upon completion of the
Offering, an additional 216,903,158 shares of Common Stock will be issuable
upon conversion of the Preferred Stock, assuming 55,000 shares of Preferred
Stock are purchased in the Offering, all holders of Notes elect Option 1 in
the Exchange and the Series 2 Debentures are converted (or 157,963,678 shares
of Common Stock if all holders of Notes select Option 2 in the Exchange).

         To the extent that outstanding options and warrants are exercised,
the percentage ownership of Common Stock of the Company's stockholders will
be diluted. Moreover, the terms upon which the Company will be able to obtain
additional equity capital may be adversely affected because the holders of
outstanding options and warrants can be expected to exercise them at a time
when the Company would, in all likelihood, be able to obtain any needed
capital on terms more favorable to the Company than the exercise terms
provided by such outstanding securities. In the event of the exercise of a
substantial number of stock options or warrants or the conversion of any
convertible securities, including the Notes and the Preferred Stock, within a
reasonably short period of time after the right to exercise commences, the
resulting increase in the amount of Common Stock of the Company in the
trading market could substantially affect the market price of the Common
Stock. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations - Overview - Capitalization."

ABSENCE OF UNITED STATES TRADING MARKET

         The Common Stock is currently traded on the VSE. There is no
established trading market for the Common Stock in the United States. The
future value of the Common Stock and Preferred Stock will depend on many
factors including:

         -        prevailing foreign currency exchange rates,

         -        operating results, and

         -        the market for similar domestic securities.

         The Company cannot assure purchasers that the Common Stock will be
listed on a U.S. exchange, that an active United States public market will
develop or that if a purchaser's Preferred Stock is converted into Common
Stock, that it will be able to resell such securities in the United States.
See "Summary - The Offering".

ABSENCE OF PUBLIC MARKET FOR THE PREFERRED STOCK; RESTRICTIONS ON TRANSFER

         There is currently no existing market for the Preferred Stock. The
Company has agreed to a reduction in the Preferred Conversion Price if the
Preferred Stock and the Common Stock issuable on conversion is not Freely
Tradable within four months after the Closing Date. See "Summary - The
Offering." Prior to the registration of the Preferred Stock and the Common
Stock issuable thereunder, the Preferred Stock offered hereby and underlying
Common Stock may only be offered or sold pursuant to an exemption from the
registration requirements of the Securities Act or pursuant to an effective
registration statement. See "Restrictions on Transfer."

CERTAIN ANTI-TAKEOVER PROVISIONS

         The Certificate of Incorporation authorizes the issuance of
preferred stock at the discretion of the Company's board of directors. The
board of directors can, without shareholder approval, issue preferred stock
with dividend, liquidation, conversion, voting or other rights that could
adversely affect the voting power or other rights of holders of the Company's
securities. In the event of issuance, the preferred stock could be used,
under certain circumstances, as a method of discouraging, delaying or
preventing a change in control of the Company. This could discourage bids for
the Company and, thereby, prevent shareholders from receiving the maximum
value for their shares. The board of directors may institute further
protections on behalf of shareholders to assure their fair consideration in
certain circumstances. The terms of the Preferred Stock prohibit the Company
from issuing additional preferred stock that would be senior to the Preferred
Stock without the consent of the holders of the Preferred Stock.

                                       27

<PAGE>

SUBORDINATION OF THE PREFERRED STOCK

         The Preferred Stock will rank PARI PASSU with Lasco Preferred and
any new issue of preferred stock that stipulates a liquidation preference
PARI PASSU with the Preferred Stock, and senior to all other present and any
future equity of the Company that does not stipulate it will be PARI PASSU
with the Preferred Stock. The Preferred Stock will be subordinate to claims
of creditors, including holders of the Company's outstanding debt instruments
(including the Notes, all production financings and other creditors). As of
March 31, 1999, the Company had $61,871,600 of indebtedness outstanding,
including $27,250,000 of indebtedness outstanding under the Notes. In
addition, at March 31, 1999, the Company had approximately $12,300,000 of
trade payables outstanding.

         Additional indebtedness will be incurred by the Company and its
subsidiaries from time to time subject to certain restrictions contained in
its credit arrangements, the Trust Indenture and the terms of the Preferred
Stock. In the event of a liquidation, dissolution or winding up of the
Company, lenders to and other creditors of the Company and its subsidiaries
would be entitled to payment in full before satisfaction of the liquidation
preference on the Preferred Stock.

EFFECT OF SUBSTANTIAL INDEBTEDNESS

         The Company's indebtedness will have several important consequences
to the holders of Notes electing to exchange Notes for Preferred Stock,
including, but not limited to, the following: (i) the holders of Preferred
Stock will be subordinate to any such debt; (ii) the Company's ability to
obtain additional financing in the future, as needed, may be limited; (iii)
the Company's leverage position and the covenants contained in its existing
contractual arrangements may limit the Company's ability to expand its
business and take advantage of certain business opportunities; and (iv) the
Company's leverage may make it more vulnerable to economic downturns, limit
its ability to withstand competitive pressures, and reduce its flexibility in
responding to changing business and economic conditions.

NO DIVIDENDS

         The Company may only pay dividends out of surplus, as defined in the
Delaware General Corporation Law, or, if no surplus is available, out of its
net profits for the fiscal year which the dividend or distribution is
declared and the preceding fiscal year. No dividends or distributions may be
declared or paid if the Company is or would be rendered insolvent by virtue
of the dividend distribution. The Company does not believe that these
restrictions will limit its ability to pay dividends on the Preferred Stock
in the future. The Company has not paid any cash dividends on its Common
Stock and does not expect to declare or pay any cash dividends on the Common
Stock or the Preferred Stock in the foreseeable future. See "Common Stock
Price Range and Dividend Policy." The Company currently intends to pay
dividends on the Preferred Stock with Common Stock. The EnCap Credit Facility
and the BOCP Credit Facility currently contain restrictions on the payment of
dividends; however, the Company intends to pay off these credit facilities
shortly after the Closing Date at which time the restriction will no longer
be applicable.

LIMITATION ON MONETARY LIABILITY OF OFFICERS AND DIRECTORS TO STOCKHOLDERS

         Section 145 of the Delaware General Corporation Law contains
provisions entitling directors and officers of the Company to indemnification
from judgments, fines, amounts paid in settlement and reasonable expenses,
including attorney's fees, as the result of an action or proceeding in which
they may be involved by reason of being or having been a director or officer
of the Company provided the officers or directors acted in good faith. The
Certificate of Incorporation contains provisions indemnifying officers and
directors of the Company to the fullest extent permitted by Delaware law.
These provisions provide, among other things, that a director of the Company
shall not be liable either to the Company or its stockholders for monetary
damages for breach of fiduciary duty as a director. These provisions may
limit the ability of the Company's stockholders to collect on any monetary
liability owed to them by an officer or director of the Company.

                                       28

<PAGE>

POSSIBLE DE-LISTING OF SECURITIES FROM THE LUXEMBOURG STOCK EXCHANGE

         If less than 100% of the holders of the Notes accept the Exchange
Offer, and if less than the equivalent of 10,000,000 Luxembourg Francs of
Notes (equal to $265,675 at the exchange rate as of April 15, 1999) remain
outstanding, the remaining holders of Notes will be subject to the risk of an
automatic delisting of the Notes from the Luxembourg Stock Exchange.

                               USE OF PROCEEDS

         The net proceeds to the Company through the sale of Preferred Stock
vary depending upon how many Notes are tendered using each option and the
amount of Preferred Stock sold. Under Assumption 1, the Company has assumed
that all Notes (Series 1 Debentures totaling $27.25 million) are exchanged
under Option 1. Under Assumption 2, the Company has assumed that all Notes
are exchanged under Option 2. In both cases the Company assumes that 55,000
shares of Preferred Stock are sold. Such proceeds are anticipated to be used
as follows (all amounts are approximate and are subject to the discretion of
the board of directors):

</TABLE>

Notes:

(1)  Anticipated to include completion of Fortenberry #1 and some or all of
     additional wells at Oakvale Dome, LaHinch, Rayburn and such other prospects
     deemed appropriate by the Company. Prospects selected are subject to change
     at the sole election of the Company.

(2)  Assumes that all lenders participating in the Old Ocean Loan other than
     lenders affiliated with EnCap will convert their indebtedness into
     Preferred Stock, and includes repurchase of the net profits interest held
     by such Old Ocean lenders. Principal amount of the Old Ocean loan is
     $2,200,000. The Old Ocean loans bears interest at the rate of 10 % per
     annum and matures on June 30, 1999.

(3)  Amount due as initial payment to Western Geophysical on 3-D seismic survey
     with respect to the Old Ocean Prospect.

(4)  Working capital needs including reduction of existing trade payables.

Pending their use, the Company intends to invest the net proceeds in short
term, high grade, interest bearing investments.

         Even if the Company receives the maximum anticipated proceeds of
$13.2 million in this Offering, such proceeds will be insufficient for the
Company to satisfy all of its trade payables, pay Western Geophysical in full
for the 3-D seismic survey with respect to the Old Ocean prospect or fund the
Company's exploration budget for the balance of 1999. The Company will
require additional financing from its existing or new lenders to obtain the
funds for such purposes. If loans from these sources plus cash from
operations are insufficient for these purposes, the Company may be required
to curtail its exploration activities.

                                       29

<PAGE>

         The actual allocation of the proceeds from this Offering will depend
on the amount of such proceeds and the Company's success in exploring for,
finding and developing oil and gas reserves. The board of directors may
reallocate the proceeds of this Offering, but currently does not intend to do
so.

DIVIDEND POLICY

     To date, the Company has not paid any dividends on its Common Stock. The
Company intends to retain its earnings, if any, to provide funds for
reinvestment in the Company's exploration, development and production
activities, and, therefore, does not anticipate declaring or paying dividends
on its Common Stock in the foreseeable future. Furthermore, payment of
dividends, if any, in the future is within the discretion of the board of
directors and will depend on the Company's earnings, if any, its capital
requirements and financial condition and other relevant factors. Presently,
the payment of dividends in cash by the Company on its Common Stock is
restricted under the terms of certain of the Company's credit facilities. The
Company has the right through December 31, 1999 to pay dividends due on its
Class A, Series I Preferred Stock with Common Stock priced at a trailing
average closing price. To date the Company has elected this option with
respect to all dividends due on the Series I Preferred Shares. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operation - Liquidity and Capital Resources."

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS


    The following discussion should be read in conjunction with information
provided above under "Cautionary Statement Regarding Forward-Looking Statements"
and "Risk Factors," and with the Company's Consolidated Financial Statements and
notes thereto attached as Appendix B and Appendix C to this Offering Circular.

OVERVIEW

    The following matters had a significant impact on the Company's results of
operations and financial position for the three months ended March 31, 1999:

         VOLUME AND PRICE INFORMATION

         Revenue for the first quarter of 1999 was significantly impacted by low
average natural gas prices. Natural gas production accounts for 87% of the
Company's total production on an equivalent MCF basis. The Company's revenues
are therefore more sensitive to gas price fluctuations than to oil price
changes. For the first quarter of 1999 natural gas prices received by the
Company for its production averaged $1.70 per MCF compared to $2.27 for the
comparable period in 1998.

         The following table summarizes volume and price information with
respect to the Company's oil and gas production for the three months ended March
31, 1999 and 1998:

</TABLE>

         OUTSTANDING DEBT

         At March 31, 1999, the Company had outstanding debt of $61.9 million.
The Company's EnCap, BOCP and Old Ocean Credit Facilities will come due on June
30, 1999. The Company anticipates that as to the indebtedness reflected by the
Old Ocean Loan, that all lenders, other than affiliates of EnCap that are owed
$100,000, will elect to convert their respective indebtedness and the mineral
interests obtained in connection with the Old Ocean Loan into Preferred Stock.
The Company anticipates that it will repay the $100,000 owed to affiliates of
EnCap under the Old Ocean Loan and the indebtedness reflected by the EnCap
Credit Facility and the BOCP Credit Facility in June with funds obtained in
connection with the Offering and new funds received in connection with either an
increase of the Shell Production Payment or through funds received in connection
with a new production payment arrangement with a new lender. The Company is
currently engaged in negotiations as to both financing options and believes such
new financing will be available in time to meet the current maturity dates. If
the Company is unable to obtain sufficient new financing to pay off the EnCap
Credit Facility and the BOCP Credit Facility, then the Company will be in
default under the applicable Credit Facility and the applicable lenders will
have the right to seek immediate repayment of the entire indebtedness due
thereunder and enforce its other remedies, which include the right to foreclose
on substantially all of the properties of the Company. Any of the foregoing
actions could cause the Company to cease operations.

         The following had a significant impact on the Company's results of
operations and financial position for the year ended December 31, 1998:

         CAPITALIZATION

         The Company completed in March and April of 1998 the private placement
of $37.5 million principal amount of Convertible Debentures, which include the
Notes. After expenses and escrow of $1.056 million for the satisfaction of
certain put rights of holders of Convertible Debentures (of which approximately
$988,000 has been


                                      33
<PAGE>

put), $32.5 million of the proceeds remained available to the Company. In
April 1999, the Company and the holders of the Notes agreed to lower the
conversion price of their debentures from Cdn. $1.70 per common share to Cdn.
$1.40 per common share in exchange for certain changes to the indentures.
Series 3 Debentureholders and the Series A Special Noteholders have agreed to
the same changes by written consent. The Notes are convertible into
29,003,555 shares of Common Stock, based on a conversion price of Cdn.$1.40
and an exchange rate of $0.6711 per Cdn.$1.00 (the exchange rate as of April
15, 1999). The remaining Convertible Debentures are convertible into
10,551,121 shares of Common Stock based on a current conversion price of
Cdn.$1.40 adjusted for the 10% penalty on conversion due to delayed
registration.

          DISCOVERY WELL

         The K. S. Byrd Well, which began producing in September of 1997,
contributed an average of 2,402 MCF per day during 1998, before including 747
MCF per day for acquired interests. The Company's interest in this well
increased with the Calibre Acquisition and the Southern Gas Acquisition.

         ACQUISITIONS

         The Company acquired certain producing properties from Lasco Energy
Partners in January 1998, Calibre Energy, L.L.C. in April 1998 and Southern Gas
Company in May 1998 (together with the Starbucks Acquisition and the Mobil
Acquisition, (the "Acquisitions"). The assets acquired in these transactions
contributed an average of 2,982 MCF per day during 1998, of which 747 MCF per
day was additional production to the Company related to the K. S. Byrd well not
included in the discussion above.

         VOLUME AND PRICE INFORMATION

         The Company's average realized price for natural gas decreased $0.56
per MCF from $2.80 per MCF for the year ended December 31, 1997 to $2.24 per MCF
for the comparable period in 1998. Income in 1998 from hedging gains increased
gas realizations by $0.18 per Mcf. The average realized oil price decreased
$8.25 per barrel from $19.08 per barrel in 1997 to $10.83 per barrel in 1998.

    The following table summarizes volume and price information with respect to
the Company's oil and gas production for the years ended December 31, 1998 and
1997, the four month period ended December 31, 1997 and the ten month period
ended August 31, 1997:

         OUTSTANDING DEBT

         At December 31, 1998, the Company had outstanding debt of $59.5 million
compared to $12.7 million at December 31, 1997. The increase reflects the
issuance of $37.5 million of Convertible Debentures, proceeds from which were
used to fund oil and gas prospect drilling, leasing and seismic data acquisition
activities in the onshore Texas and Mississippi Gulf of Mexico region, repayment
of a portion of the Company's outstanding debt and other working capital uses.
In addition, the Company entered into a financing agreement with Shell Capital
whereby the Company sold a term production payment to Shell Capital for $7.0
million. The Company's debt-to-capitalization ratio at December 31, 1998 was
78.3%.

THREE MONTHS ENDED MARCH 31, 1999 VS. THREE MONTHS ENDED MARCH 31, 1998

         For the three months ended March 31, 1999, revenue from crude oil and
natural gas production increased 32% over the same period in 1998. Natural gas
contributed 88% and crude oil contributed 12% of total oil and gas production
revenue.

         Natural gas sales increased 30%, from $932,400 for the three months
ended March 31, 1998 to approximately $1.2 million for the same period in 1999;
however, the impact of increased production was significantly reduced by the
decline in natural gas prices. Production for the first quarter of 1999
increased significantly over the comparable prior year period due primarily to
production from the assets purchased in the second quarter of 1998 and
production from new wells drilled and completed. This increase in production
improved revenue from the 1999 period by $681,800. The average realized price
for natural gas sales declined from $2.27 per MCF in the first quarter of 1998
to $1.70 per MCF in the comparable 1999 period decreasing revenues by $406,700.

         For the three months ended March 31, 1999, oil sales increased 51% to
$163,500, compared to $108,400 for the same period in 1998, due primarily to
sales of production from properties acquired in the second quarter of 1998 and
from new wells drilled and completed. This increase in production improved
revenue for the first quarter of 1999 by approximately $99,500. The Company's
average realized price for sales of crude oil in the first quarter of 1999
decreased by $2.58 per barrel, or 21%, decreasing revenue by $44,400 compared to
the same period in 1998.

         The Company's depreciation, depletion and amortization ("DD&A") expense
for the first quarter of 1999 totaled $1.2 million compared to $676,600 in the
comparable period for 1998. Full cost DD&A totaled $1.1 million for the three
months ended March 31, 1999 compared to $621,600 for the same period in 1998.
The increase in DD&A is consistent with a higher amortizable asset base and an
increase in production for the 1999 period compared to the prior year period. On
an equivalent MCF basis, full cost DD&A decreased $0.04 per MCFE, from $1.34 per
MCFE for the three months ended March 31, 1998 to $1.30 per MCFE in the
comparable 1999 period. DD&A of other assets for the first quarter of 1999
totaled $102,500, an increase of $47,500 over the comparable period in 1998, due
primarily to an increase in the related asset base.

         Operating costs, including lease operating expense ("LOE") and
production taxes, increased 30% from $129,200 in the first quarter of 1998 to
$168,200 for the same period in 1999. The increase was due primarily to
increased production from wells drilled or acquired since the prior year period.
For the three months ended March 31, 1999, LOE, excluding severance taxes,
totaled $138,000 compared to $111,100 for the comparable period in 1998. On an
equivalent MCF basis, average LOE for the first quarter of 1999 decreased from
$0.24 per MCFE in 1998 to $0.17 per MCFE in the same 1999 period.

         General and administrative expense for the three months ended March 31,
1999 decreased $552,200, or 37%, compared to the same period in 1998. On an
equivalent MCF basis, general and administrative expenses declined 64% to $1.15
per MCFE for the three months ended March 31, 1999 compared to $3.19 per MCFE
for the same period in 1998. The decrease in G&A costs was due primarily to
lower compensation expense generated by staff reductions during the fourth
quarter of 1998 and the first quarter of 1999. These staff reductions, as well
as salary reductions for certain of the remaining employees, are expected to
significantly reduce G&A costs in 1999.

         Interest expense for the three months ended March 31, 1999 totaled $1.0
million compared to $1.2 million in the comparable prior year period. Average
debt was approximately $59.8 million for the first quarter of 1999, resulting in
gross interest costs of $2.0 million. Other financing costs include the
amortization of discount of $77,800. Partially offsetting these costs was
capitalized interest of $1.0 million, which is based on the carrying value of
unproved properties. Financing costs also included amortization of debt issuance
costs totaling $582,030


                                      35
<PAGE>

for the first quarter of 1999. For the first quarter of 1998, average debt
was approximately $25.6 million, resulting in gross interest costs of
$857,000. Other financing costs included the amortization of the original
issue discount for the EnCap NPI and warrants of $512,400. Partially
offsetting these costs was capitalized interest of $171,400. Amortization of
debt issuance costs totaled $53,800 for the first quarter of 1998.

         Other income (expense) for the three months ended March 31, 1999
included interest income of $88,200 partially offset by losses on the sale of
marketable securities totaling $58,600. For the comparable period in 1998 other
income included interest income of $29,000 and gains on the sale of marketable
securities totaling $108,800.

         For the three months ended March 31, 1999, the Company reported a net
loss applicable to common stockholders of $2.7 million, or $0.08 per share,
compared to a net loss of $2.4 million, or $0.08 per share, in the comparable
1998 period. Weighted average shares outstanding increased from approximately
30.6 million in the first quarter of 1998 to over 33.7 million in the comparable
1999 period as a result of the issuance of Common Stock as dividend payment on
preferred shares as well as the exercise of warrants and options in the second
half of 1998.

YEAR ENDED DECEMBER 31, 1998 VS. YEAR ENDED DECEMBER 31, 1997

         For the year ended December 31, 1998, the Company reported a net loss
applicable to common stockholders, of $11.9 million, or $0.37 per share,
compared to a net loss of $4.4 million, or $0.18 per share, in the comparable
1997 period. Weighted average shares outstanding increased from approximately
24.1 million in 1997 to over 32.4 million in 1998 as a result of the conversion
and exercise of warrants in late 1997 and the issuance of Common Stock to
acquire certain properties in 1998 and to pay interest and dividends on the
Lasco Acquisition note and subsequent preferred shares.

         For the year ended December 31, 1998, revenue from crude oil and
natural gas production increased 378% over the same period in 1997. Natural gas
contributed 91% and crude oil contributed 9% of total oil and gas production
revenue.

         Natural gas sales increased over 460%, from $804,700 for the year ended
December 31, 1997 to approximately $4.5 million for the same period in 1998, as
the impact of increased production more than offset the impact of the decline in
natural gas prices. Production for 1998 increased significantly over the
comparable prior year period due primarily to production from the assets
purchased in the Acquisitions and production from the K. S. Byrd Well. This
increase in production improved revenue for 1998 by $4.8 million. The average
realized price for natural gas sales declined from $2.80 per MCF in 1997 to
$2.24 per MCF in the comparable 1998 period, decreasing revenues by $1.1
million. Income in 1998 from hedging gains increased gas realizations by $0.18
per Mcf.

         For the year ended December 31, 1998, oil sales increased 91% to
$440,500, compared to $231,100 for the same period in 1997, due primarily to
sales of production for properties acquired in the Acquisitions and production
from the Reedy Creek properties. This increase in production improved revenue
for 1998 by approximately $544,700. The Company's average realized price for
sales of crude oil in 1998 decreased by $8.25 per barrel, or 43%, decreasing
revenue by $335,300 compared to the same period in 1997.

         The Company's depreciation, depletion and amortization ("DD&A") expense
for 1998 totaled $3.2 million compared to $854,100 in the comparable period for
1997. Full cost DD&A totaled $2.8 million for the year ended December 31, 1998
compared to $709,200 for the same period in 1997. The increase in DD&A is
consistent with the increased production for 1998 compared to the prior year
period. Included in DD&A for the year ended December 31, 1997, was $221,000 of
non-cash charges attributable to a price-related reduction in the book value of
the Company's oil and gas reserves. On an equivalent MCF basis, full cost DD&A
decreased $0.71 per MCFE, from $1.97 per MCFE for the year ended December 31,
1997 to $1.26 per MCFE in the comparable 1998 period. DD&A of other assets for
1998 totaled $305,700, an increase of $160,800 over the comparable period in
1997 due primarily to an increase in the related asset base.

         Operating costs, including lease operating expense ("LOE") and
production taxes, increased 763% from $111,500 in 1997 to $962,700 for the same
period in 1998. The increase was due primarily to increased production from
wells drilled or acquired since the prior year period. For the year ended
December 31, 1998, LOE, excluding severance taxes, totaled $860,200 compared to
$86,500 for the comparable period in 1997. On an equivalent MCF basis, average
LOE for 1998 increased from $0.24 per MCFE in 1997 to $0.38 per MCFE in 1998.
This increase is primarily due to the Lasco Acquisition that was comprised of
older, lower rate wells.


                                      36
<PAGE>

         General and administrative expense for the year ended December 31, 1998
increased over $1.9 million, or 52%, compared to the same period in 1997. On an
equivalent MCF basis, general and administrative costs declined 76% to $2.56 per
MCFE for the year ended December 31, 1998 compared to $10.51 per MCFE for the
same period in 1997. The increase in G&A costs was due primarily to higher
compensation expense generated by a larger staff. The Company began 1998 with 26
employees, increasing to 37 employees during the year. Staff reductions during
the fourth quarter of 1998 reduced total employees to 29 at year-end. Further
staff reductions during the first quarter of 1999 reduced total employees to 21
at March 31, 1999. These staff reductions, as well as salary reductions for the
majority of the remaining employees, are expected to significantly reduce G&A
costs in 1999. The overall high level of general and administrative expenses in
1997 was due to the initial costs associated with creating and managing the
Company's extensive capital program.

         Interest expense for the year ended December 31, 1998 totaled $5.8
million compared to $689,219 in the comparable prior year period. The increase
is due primarily to the financing arrangements under the EnCap Credit Facility
entered into in December 1997 and interest on the $37.5 million principal amount
of Convertible Debentures issued in March and April of 1998. Average debt was
approximately $44.6 million for 1998, resulting in gross interest costs of $4.8
million. Other financing costs include the amortization of the original issue
discount for the EnCap NPI (defined below) of $1.7 million and the amortization
of deferred loan and issuance costs of $1.2 million. Partially offsetting these
costs were capitalized interest of $1.9 million, which is based on the carrying
value of unproved properties.

         Other income (expense) for the year ended December 31, 1998 included a
charge of $1.0 million due to the termination of a key employee of the Company
recorded in December 1998 to reflect settlement of his employment contract. Such
settlement will be paid out through January 2001. Offsetting this expense were
interest income of $573,609 and gains on the sales of marketable securities
totaling $24,971. For the comparable period in 1997, interest income of $77,844
was offset by losses on the sales of marketable securities totaling $86,824.

FOUR MONTHS ENDED DECEMBER 31, 1997 AND TEN MONTHS ENDED AUGUST 31, 1997

         The Company reported a net loss of $2,739,300, or $0.10 per share, for
the four months ended December 31, 1997 and $1,917,100 or $0.09 per share, for
the ten months ended August 31, 1997. Weighted average shares outstanding were
27.9 million for the four months ended December 31, 1997 and 21.9 million for
the ten months ended August 31, 1997.

         Natural gas sales for the four months ended December 31, 1997 and the
ten months ended August 31, 1997 totaled $624,400 and $256,000, respectively.
Production averaged 1,833 MCFD for the four-month period ended December 31, 1997
at an average price of $2.79 per MCF and 276 MCFD for the ten-month period ended
August 31, 1997 at an average price of $3.05 per MCF. The K.S. Byrd Well began
production in September 1997 and averaged 1,605 MCFD for the four months ended
December 31, 1997.

         The Company's crude oil sales for the four months ended December 31,
1997 and the ten months ended August 31, 1997 totaled $83,500 and $188,200,
respectively. Production averaged 36.9 barrels per day and 30.5 barrels per day,
respectively, for the four-month period ended December 31, 1997 and the
ten-month period ended August 31, 1997. The Company's average realized price for
sales of crude oil for the four month period ended December 31, 1997 and the
ten-month period ended August 31, 1997 were $18.54 per barrel and $20.28 per
barrel, respectively.

         For the four months ended December 31, 1997, DD&A expense totaled
$634,500 and for the ten months ended August 31, 1997, DD&A expense was
$240,400. Full cost DD&A averaged $2.32 per MCFE for the four months ended
December 31, 1997 and $1.07 per MCFE for the ten months ended August 31, 1997,
due primarily to a ceiling test write-down of $221,000 at December 31, 1997.

         Operating costs totaled $49,800 and $68,500, respectively, for the four
month period ended December 31, 1997 and the ten month period ended August 31,
1997. LOE, excluding severance taxes, totaled $42,700 and $45,600 for the same
periods, respectively. On an equivalent barrel basis, LOE for the four months
ended December 31, 1997 averaged $0.17 per MCFE and for the ten months ended
August 31, 1997 averaged $0.33 per MCFE.


                                      37
<PAGE>

         General and administrative costs totaled $2,087,100 for the four months
ended December 31, 1997 and $2,026,400 for the ten months ended August 31, 1997.
On an equivalent MCF basis, general and administrative expenses were $8.32 per
MCFE for the four months ended December 31, 1997 and $14.53 per MCFE for the ten
months ended August 31, 1997. General and administrative costs were significant
during these periods and reflected establishment of the infrastructure necessary
to sustain the planned expansion of oil and gas operations and the Company's
desired position as operator of many of its prospects. Costs included signing
bonuses paid to professional and senior management staff as inducements to leave
their previous employment and join the Company, legal and accounting fees, and
the settlement of a lawsuit filed by a former employee.

         Net financing costs for the four months ended December 31, 1997 were
$625,100, and consisted of gross interest expense of $286,700, the amortization
of the original issue discount for the EnCap NPI of $427,500 and amortization of
deferred loan costs of $42,900. Partially offsetting these costs was capitalized
interest of $108,200 and interest income of $23,800. For the ten months ended
August 31, 1997, gross interest expense of $49,300 was more than offset by
interest income of $59,200. The higher financing costs in the four month period
ended December 31, 1997 reflects the Company's increase in long-term debt from
$759,300 at August 31, 1997 to $14.7 million at December 31, 1997. This increase
in debt relates to the EnCap Credit Facility, entered into in late 1997, that
was used to finance the Oakvale Dome Field and Old Ocean acquisitions and
related development.

         Other revenue for the four-month period ended December 31, 1997 and the
ten-month period ended August 31, 1997 represents losses on the sale of
marketable securities of $50,900 and $35,900, respectively.

LIQUIDITY AND CAPITAL RESOURCES

         The Company's primary cash needs are for exploration, development and
acquisition of oil and gas properties, payment for the acquisition and
processing of seismic data, the repayment of trade payables and repayment of
principal and interest on outstanding debt. The Company has budgeted $11.3
million to fund planned capital expenditures on its prospects during 1999. The
Company's sources of financing include net proceeds from the Offering, a
tentative commitment of equity from an affiliate of EnCap, revenue generated
from operations, ongoing sales of non-core assets and proceeds from production
payment facilities. Based on the foregoing, the Company will require additional
capital from more than one of the sources identified above to fund its ongoing
activities and capital budget. If the Company is unable to obtain such
additional capital, the Company will either have to sell interests in its
prospects to fund its drilling program, curtail its exploration activities
and/or curtail ongoing activities. Such curtailing of activities could include
reducing the number of wells drilled, slowing activities on projects that the
Company operates, selling additional interests in the Company's prospect
inventory or a combination of the foregoing. In the absence of any new funding,
the Company will have inadequate liquidity to satisfy its existing contractual
obligations and to continue operations in its current form.

         Many of the factors that may affect the Company's future operating
performance and long-term liquidity are beyond the Company's control, including,
but not limited to, oil and natural gas prices, governmental actions and taxes,
the availability and attractiveness of financing and its operational results.
The Company continues to examine alternative sources of long-term capital,
including bank borrowings, the issuance of debt instruments, the sale of Common
Stock or other equity securities, the issuance of net profits interests, sales
of promoted interests in its prospects, and various forms of joint venture
financing. In addition, the prices the Company receives for its future oil and
natural gas-production and the level of the Company's production will have a
significant impact on future operating cash flows.

         LIQUIDITY

         At March 31, 1999, the Company had cash and cash equivalents on hand of
$565,200 and working capital deficit of $35.1 million, as compared to a cash
balance of $2.3 million and a working capital deficit of $27.4 million as at
December 31, 1998 and a cash balance of $3.2 million and a working capital
deficit of $15.3 million at December 31, 1997. The Company's ratio of current
assets to current liabilities was 0.16:1 at March 31, 1999, 0.25:1 at December
31, 1998 and 0.37:1 at December 31, 1997. The working capital deficit and low
current ratio is primarily due to the EnCap Credit Facility discussed below,
repayment of which is due by June 30, 1999.


                                      38

         CASH FLOWS

         Cash flows used in operations totaled $153,600 for the three months
ended March 31, 1999, compared to $4.1 million for the year ended December 31,
1998. Cash used in investing activities for the quarter ended March 31, 1999 and
year ended December 31, 1998 was $4.1 million and $35.4 million, respectively.
During the first quarter of 1999, costs incurred for exploration and development
expenditures totaled $4.1 million and capital expenditures for furniture and
equipment totaled $64,200. Partially offsetting these costs was proceeds of
$128,100 from the sale of marketable securities. Cash outlays for exploration
and development expenditures totaled approximately $36.3 million and capital
expenditures for furniture and equipment totaled $745,400 during the year ended
December 31, 1998. Partially offsetting these costs were $1.1 million in
proceeds from the sale of non-core properties and $1.1 million in proceeds from
the sale of marketable securities.

         Cash provided by financing activities totaled $2.4 million for the
first quarter of 1999 and included borrowings under the BOCP Credit Facility of
approximately $2.7 million and repayments under the Shell Production Payment
totaling approximately $352,500. For the year ended December 31, 1998 cash
provided by financing activities totaled approximately $38.7 million and
consisted primarily of proceeds from the issuance of Convertible Debentures
including the Notes. The Company also borrowed $3.0 million under the EnCap
Credit Facility and repaid $5.0 million thereunder during the first quarter of
1998. In December 1998, the Company entered into a financing agreement with
Shell Capital whereby the Company sold a term production payment to Shell
Capital for $7.0 million. Also in December, the Company repaid $2.9 million on
Tranche A and Tranche B loans under its BOCP Credit Facility resulting in net
borrowings under that Facility of $2.3 million for the year ended December 31,
1998. The Company also borrowed $2.2 million for the acquisition of property
interests from Mobil through a short term, secured advance from investors
introduced by the Agent (referred to herein as the Old Ocean Loan).

CREDIT FACILITIES

         ENCAP CREDIT FACILITY

         In 1999, the Company entered into a $20 million credit agreement (the
"EnCap Credit Facility") with EnCap Capital Fund III, L.P. ("EnCap Energy")
consisting of a promissory note for $12,000,000 (the "Original Note") and a
promissory note for $8,000,000 (the "Supplemental Note"; collectively, the
"Notes"). The Original Note bears interest at 10% per annum through December 31,
1998 and at 18% per annum thereafter. The Note is due, with accrued interest, by
June 30, 1999. The Supplemental Note was repaid in full and is no longer
outstanding. Under the terms of the Convertible Debentures (other than the
Notes), the Company has agreed to limit borrowings under the EnCap Credit
Facility to $12,000,000, all of which is outstanding and due June 30, 1999
following an extension obtained by the Company. The proceeds from the facility
were applied to the acquisition of Oakvale Dome ($8,000,000), and Old Ocean
properties and the drilling and completion of certain development wells
($4,000,000). A first lien on certain properties and a second lien on certain
other properties secure the Original Note. Mr. Tomlinson, Calibre and certain
affiliates of Calibre guarantee the Original Note.

         Under the terms of the Original Note, the Company agreed to convey to
EnCap Energy, on January 1, 1999, a 25% net profit interest (the "EnCap NPI")
from the properties acquired with the proceeds of the borrowing. In connection
with the original granting of the EnCap NPI, the Company recorded a discount on
the Original Note of $2,102,180 as of December 31, 1997. The discount has been
amortized over the term of the Original Note. The carrying amount of the oil and
gas interests has been reduced by the same amount.

         Under the terms of the Supplemental Note, EnCap Energy was issued
warrants to purchase up to 1.5 million shares of Common Stock at an exercise
price of $1.28 per share. In connection with the issuance of these warrants, the
Company recorded a discount on the Supplemental Note of $367,881 as of December
31, 1997. This discount is being amortized over the term of the Supplemental
Note. Pursuant to a financing agreement dated November 4, 1998 with EnCap Energy
and as consideration for enabling additional funding through the BOCP Credit
Facility, the warrants were re-priced to $0.46475 per share.

         BOCP CREDIT FACILITY

         In December 1998, the Company's loan agreement with Bank One NA ("Bank
One") was purchased by BOCP Energy Partners, L.P. ("BOCP"), an affiliate of
EnCap. Pursuant to an assignment of note and liens dated


                                      39
<PAGE>

December 29, 1998, Bank One assigned the original loan agreement, together
with all loan documents referred to therein, to BOCP. In December 1998, the
principal amount then outstanding under Tranche A of $2.9 million plus
interest was repaid and, per amendments to the loan agreement, no further
advances will be requested or made under Tranche A. Interest accrued on
Tranche A at prime plus 2.0% and on Tranche B at a rate of 15% per annum,
payable monthly.

The amendments also modified the terms of Tranche B of the credit facility as
follows:

(1)  Maximum availability of $6,000,000;

(2)  No advances on Tranche B will be requested or made on or after April 30,
     1999;

(3)  Maturity date of June 30, 1999; and

(4)  Interest rate of prime plus eight percent per annum through and including
     December 31, 1998, and fifteen percent per annum from and after January 1,
     1999.

The present outstanding balance of the BOCP Credit Facility is $6.0 million. All
interest accrued on Tranche B remains unpaid and owing and is due on June 30,
1999. The Company has reached a standstill agreement covering certain covenants
of which the Company is currently in violation and received an extension in the
maturity date to June 30, 1999.

         SHELL FINANCING

         In December 1998, the Company entered into a financing agreement with
Shell Capital, Inc. ("Shell Capital") whereby the Company sold a term production
payment ("Shell Production Payment") to Shell Capital for $7.0 million. The
production payment comprised a dedication of 42% of the net revenues from the
Wausau, Oak Hill and East Morgantown properties, 23.1% of Oakvale Dome's Howell
well, 12.2% of Oakvale Dome's Fortenberry well and 38.5% of Oakvale Dome's Byrd
well. The interests conveyed are subject to future adjustment. The Shell
Production Payment is secured solely by the properties and is non-recourse to
the Company. Following full pay-out ($7.0 million plus a 15% rate of return) of
the production payment, the dedicated revenue interest is returned to the
Company less a permanent royalty interest equal to 8.75% of the Company's net
revenue interest in Wausau, Oak Hill and East Morgantown; 4.8% of the Howell and
Byrd wells; and 2.5% of the Fortenberry well. The Company has the right to buy
back the production payment at a stated rate of return of 25% plus a payment of
$1.0 million. In connection with the right to buy back the permanent overriding
royalty interest conveyance, the Company recorded a discount on the financing of
$1.0 million. The carrying amount of the oil and gas interests has been reduced
by the same amount. Shell Capital further agreed to expand the Shell Production
Payment up to $25.0 million provided that the Company sell certain properties,
enter into a payment schedule for amounts owed to an industry partner, raise
additional capital and obtain certain minimum results from current development
drilling activity. The Company is currently negotiating with Shell Capital and
other parties to complete the expansion of the Shell Production Payment or the
creation of a new production payment.

         This financing has been classified as debt on the balance sheet and
began being reduced in 1999 as production is delivered to Shell under the terms
of the contract. Volumes delivered to Shell are reported as revenue at prices
received by Shell. Interest expense is recorded based on a rate of 15% per
annum.

         OLD OCEAN LOAN

         On December 31, 1998, the Company obtained a $2.2 million loan from a
group of lenders led by the Agent, the proceeds being used to acquire additional
interests in the Old Ocean Project from Mobil. The loan is due, through
extension, on June 30, 1999, and is secured by the acquired interests and a
junior lien on certain other properties. The Company has proposed that it repay
the loan through the issuance of Preferred Stock. The Company also granted the
providers of the facility with an overriding royalty that is to be converted
into a participating net profits interest, which interest can be repurchased by
the Company for $1.1 million in cash or stock and $1.1 million principal amount
of warrants. The Company has proposed repurchasing the overriding interest and
participating net profits interest with Preferred Stock as well. One lender of
$100,000 has elected to accept cash for repayment of its portion of the loan and
purchase of the overriding interest.

CONVERTIBLE DEBENTURES

         In April 1998, the Company issued the Series A Special Notes (which
Notes and the Debentures into which they are exchangeable are referred to herein
as the Series 2 Debentures) to Canadian investors and the Series 3 Debentures to
United States investors on substantially similar terms to the Notes. It is the
Company's intention to offer holders of the Series 3 Debenture the ability to
exchange their special notes or debentures into Preferred Stock on terms which
are not any more favorable, in whole or in part, than those attaching to the
Preferred Stock and to the terms set out in the Letter of Transmittal. The
holders of Series 2 Debentures (which amount to $1,652,000) are not being
offered the opportunity to exchange their Series 2 Debentures into Preferred
Stock.

CHANGES IN ISSUED SHARE CAPITAL

         On March 31, 1999, the Company agreed to issue 1,057,000 shares of
Common Stock to certain holders of the Series 3 Debentures in exchange for
interest owed and due on March 31, 1999. Also on March 31, 1999, the Company
agreed to issue 541,700 shares of Common Stock to a holder of Series 3
Debentures to retire $250,000 principal amount of the debentures. The shares
will be issued following receipt of VSE acceptance.

YEAR 2000

         The Company operates on an externally designed software package that is
compliant with the year 2000. The year 2000 problem is the result of software
that uses two digits (rather than four) to define the applicable year. Any
software or hardware that uses time-sensitive coding may recognize a day using
"00" as the year 1900 rather than the year 2000, which could result in
miscalculations or system failures. The Company is attempting to identify other
potential areas of risk and has begun addressing these in its planning,
purchasing and daily operations. Based on preliminary information, costs of
addressing potential problems are not currently expected to have a material
adverse impact on the Company's financial position, results of operations, or
cash flows in future periods. If, however, the Company, its customers, or
vendors are unable to adequately resolve such processing issues in a timely
manner, the Company's operations and financial results may be adversely
affected.

                             BUSINESS AND PROPERTIES

GENERAL

         The Company is an independent energy company engaged in the exploration
for and development of oil and natural gas. The Company has interests in over 25
oil and gas prospects and projects primarily in the United States Gulf Coast
areas of Mississippi, Texas and Louisiana. Most of these prospects have been,
are being, or are expected to be, enhanced with 3-D seismic data and CAEX
technologies. The 3-D seismic data, including current surveys, will cover over
820 square miles. The Company's 1999 capital budget provides for a total of
$11.3 million for drilling and prospect development. Of such amount,
approximately $7.3 million is budgeted for development drilling, approximately
$1.0 million is budgeted for exploratory drilling, testing, and subsequent
completions, $2.3 million is budgeted for seismic data acquisitions and the
remainder is budgeted primarily for leasehold purchases. The Company believes
that its prospects represent a diverse array of technology enhanced, 3-D seismic
confirmed oil and gas exploration prospects.

         A substantial portion of the Company's growth has been through
acquisitions, including the following 1998 acquisitions:

(i)      in January 1998 the acquisition of certain oil and gas prospects from
         Lasco Energy Partners, L.P. ("Lasco") (the "Lasco Acquisition");

(ii)     the acquisition on April 22, 1998 of certain oil and gas property
         interests of Calibre (the "Calibre Acquisition") (certain closing
         matters to be completed);

(iii)    the acquisition on May 1, 1998 of certain oil and gas properties from
         Southern Gas Corporation (the "Southern Gas Acquisition");

(iv)     the acquisition effective in July 1998 of certain oil and gas property
         interests from Starbucks Trust (the "Starbucks Acquisition") (certain
         closing matters to be completed); and

(v)      the acquisition on December 29, 1998 of the Mobil interest in the Old
         Ocean project (the "Mobil Acquisition", the Lasco Acquisition, the
         Calibre Acquisition, Southern Gas Acquisition, Starbucks Acquisition
         and Mobil Acquisition are referred to collectively herein as the
         "Acquisitions").

         The foregoing transactions, other than the Mobil Acquisition have
received regulatory acceptance by the VSE. Regulatory acceptance for the Mobil
Acquisition is pending and Company expects to receive this acceptance in due
course. If this acceptance is not received, the Company may be required to
modify certain aspects of these transactions, failing which the VSE may impose
regulatory sanctions, which could include delisting of the Company's Common
Stock from the VSE.

 RECENT DEVELOPMENTS

         In December 1998, the Company entered into a financing agreement with
Shell Capital, Inc. ("Shell Capital") whereby the Company sold a term production
payment to Shell Capital for $7.0 million. The Shell Production Payment
comprised a dedication of 42% of net revenues from the Wausau, Oak Hill and East
Morgantown Properties; 23.1% of Oakvale Dome's Howell well; 12.2% of Oakvale
Dome's Fortenberry well; and 38.5% of Oakvale Dome's Byrd well. The production
payment is secured solely by the properties and is non-recourse to the Company.
Following full payout of the production payment, the dedicated revenue interest
will be returned to the Company less a permanent royalty interest equal to 8.75%
of the Company's net revenue interest in Wausau, Oak Hill and East Morgantown;
4.8% of the interest in the Howell and Byrd wells; and 2.5% of the Fortenberry
interest. The Company has the right to buy back the production payment at a
stated rate of return of 25.0% plus $1 million. Shell Capital has agreed to
expand its term production payment up to $25.0 million provided that the Company
sell certain properties, enter into a payment schedule for amounts owed to an
industry partner, raise additional capital and obtain certain minimum results
from current development drilling activity. The Company is currently negotiating
with Shell Capital and other parties to complete the expansion of the term
production payment and believes that it will meet the specified requirements.

         In December 1998, the Company acquired for $2.0 million all of Mobil's
right, title and interest in the deep rights below the existing production in
the Old Ocean Prospect. The Company has combined this interest with its


                                      42
<PAGE>

contractual rights and ownership in the immediate area and is currently
attempting to secure one or more industry partners to purchase 37.5% of the
Company's ownership in the Old Ocean Prospect. The Company paid for this
acquisition through the Old Ocean Loan.

         In January 1999, the Company acquired, on behalf of the Company and its
partner in the Wausau prospect, a gas pipeline in Mississippi for approximately
$425,000 to provide access for gas sales. Included in the purchase were a 100%
and a 93.75% BPO working interest in two producing gas wells. The Company does
not anticipate these wells reaching pay-out. The Company owns a 53.8% interest
in the pipeline and the Fairchild #1 well and a 50.5% interest in the A. Foote
Estate #1 well. Gas reserves net to the Company are estimated to be in excess of
150 MMCFG and net production of over 150 MCFGPD.

         In May 1999, the Company closed the sale of its interests in the Lisbon
Field, comprising essentially all of its proven reserves in Louisiana, for
$507,500 in gross proceeds to an unrelated party.

         In June 1999, the Company completed the drilling of its Fortenberry #1
well to a depth of 16,126 feet at Oakvale Dome Field in Jefferson Davis County,
Mississippi. The Company elected to not drill deeper to the projected depth of
16,250 feet due to concerns that additional drilling difficulties could be
encountered in the side-track hole. Open hole electric and porosity logs which
run to a depth of 16,088 feet, indicate a total of 80 net feet of hydrocarbon
bearing sands in the primary objectives in the Hosston Formation at depths
between 15,792 feet and 15,992 feet. An additional four feet of net pay was
measured by electric and porosity logs in the lower Booth zone starting at a
depth of 16,075 feet based on mud logs from the original side-track hole. The
remainder of the zone could not be logged due to existing hole conditions. The
Company owns a 70% working interest in the well and an average 64% working
interest in the field. The Company is proceeding to complete the well for
production.

         The Company plans to co-mingle the 42 net feet in the Harper and the 38
net feet in the Booth for production. Both of these zones are producing in the
adjacent fault block to the north out of the Company's first two wells in the
field, the K. S. Byrd #1 and the Howell #1. The top 22 feet of the
partially-logged lower Booth have been cased and are expected to be added to the
producing stream with the Harper and Booth.

STRATEGY

         The Company's strategy is to expand its reserves, production and cash
flow through the implementation of an exploration and exploitation program that
focuses on:

         (i) obtaining dominant positions in core areas of exploration and
         development in under-exploited areas in or adjacent to fields and
         trends that have historically produced hydrocarbons in significant
         quantities;

         (ii) enhancing the value of its prospects and reducing exploration
         risks through the use of 3-D seismic data and CAEX technologies;

         (iii) maintaining an experienced technical staff with the expertise
         necessary to take advantage of the Company's proprietary 3-D seismic
         data and CAEX technologies;

         (iv) adding reserves and production using modern reservoir stimulation
         methods; and

         (v) retaining control over critical exploration decisions.

         OBTAIN DOMINANT POSITION IN CORE AREAS

         The Company has identified core areas for exploration and development
in geological trends with demonstrated histories of prolific natural gas
production from high porosity reservoir rocks with profiles suitable for seismic
evaluation. The Company believes that by obtaining substantial working
interests, related 3-D seismic data and significant acreage positions within its
core areas, it will be able to achieve a dominant position in focused portions
of those areas. With a dominant leasehold position, the Company believes it can
better control the core areas, drilling opportunities and future production and
can attempt to minimize costs through economies of scale and other efficiencies
inherent in its focused approach. Such cost savings and efficiencies include the
ability to use the Company's 3-D seismic data to reduce drilling risks and lower
its leasehold acquisition costs by identifying and purchasing leasehold
interests only in those focused areas in which the Company believes drilling is
most likely to be successful.


                                      43
<PAGE>

         USE OF 3-D SEISMIC AND CAEX TECHNOLOGIES

         The Company attempts to enhance the value of its prospects through the
use of 3-D seismic data and CAEX technologies, with an emphasis on direct
hydrocarbon detection technologies. These technologies create computer generated
3-dimensional displays of subsurface geological formations that enable the
Company's professional staff to detect seismic anomalies in structural features
that are not apparent in 2-D seismic surveys. The Company believes that 3-D
seismic data, if properly used, will reduce drilling risks and costs by reducing
the number of dry holes, optimizing well locations and reducing the number of
wells required to exploit a discovery.

         EXPERIENCED TEAM

         The Company maintains an experienced staff, including engineers,
geologists, geophysicists, a landman and other technical personnel. Such
professional staff has on average 18 years of experience in the oil and gas
industry.

         USE OF MODERN RESERVOIR STIMULATION METHODS AND NEW DRILLING TECHNOLOGY

         In addition to applying the latest in 3-D seismic and CAEX technology,
the Company uses the latest in industry reservoir stimulation and directional
drilling techniques. For example, many of the Company's development and
exploitation opportunities are "tight" reservoirs in which modern stimulation
practices may significantly increase production.

         CONTROL OF DRILLING FUNCTIONS

         The Company believes that controlling the most critical functions in
the drilling process will enhance its ability to develop successfully its
prospects. The Company has acquired a majority interest in many of its
prospects, including interests in most of the 3-D seismic data relating to those
prospects. In many cases where the Company does not own a majority interest in a
prospect the Company still owns a greater interest than that of any other
working interest owner. As a result, in many of its prospects, the Company will
be able to influence the areas to explore, manage the land permitting and option
process, determine seismic survey areas, oversee data acquisition and
processing, prepare, integrate and interpret the data and identify each prospect
drillsite. In addition, the Company will be the operator of many of the wells
drilled on these prospects.

         BACKGROUND

         The Company was originally formed on February 9, 1981 for the purpose
of conducting mineral exploration in Canada. In 1989, the Company changed its
focus and concentrated on investment and merchant banking activities. At that
time, the Company wrote off its mineral property costs and ceased all mineral
exploration activities. From 1991 to 1993, the Company diversified into the
acquisition and development of oil and gas properties. During 1996, the Company
sold substantially all of its investments outside of oil and gas and refocused
operations on oil and gas exploration and development in the United States.
Effective as of October 31, 1996, the Company acquired Texstar and as a result,
the Company focused its operations on oil and gas exploration and development in
the United States, specifically the Gulf Coast areas of Mississippi, Texas and
Louisiana. Former shareholders of Texstar acquired control of the Company and
Texstar became a wholly owned subsidiary of the Company. In July 1997, the
Company changed its name from Benz Equities Ltd. to Benz Energy Ltd. The Company
has migrated to the state of Delaware and is now a Delaware Corporation under
the name Benz Energy Inc.

THE PROSPECTS

         The Company's prospects are located primarily in the Gulf Coast areas
of Mississippi, Texas and Louisiana. As of December 31, 1998, the Company owned
interests in 21 producing wells it operated and also owned non-operated
interests in 13 producing wells in Louisiana, Mississippi, and Texas. Daily
production from both operated and non-operated wells net to the Company's
interest averaged 5,506 MCFGD and 111.4 BOPD for the year ended December 31,
1998. Daily production as of March 31, 1999, was approximately 9,547 MCFGD and
219 BOPD. Each of the Company's prospects differs in scope and character and
consists of one or more types of assets, such as 3-D seismic data, working
interests in oil and gas leases, oil and gas lease options, contractual rights
to earn a working interest in oil and gas leases, royalty interests or other
mineral interests. Most of the Company's prospects


                                      44
<PAGE>

have been, are being, or are expected to be enhanced with 3-D seismic data
and CAEX technologies. The 3-D seismic data acquired will, when completed for
the existing prospects, cover over 820 square miles (gross). The table below
gives certain information regarding the location, objectives, and present
status of the Company's most significant prospects as of December 31, 1998:

         Preferred Stock.


         Below are descriptions, as of December 31, 1998, unless otherwise
indicated, of the Company's most significant prospects.

         OAKVALE DOME

         The Oakvale Dome Prospect, located in Jefferson Davis County,
Mississippi, is the Company's most significant producing property. The Company
owns approximately 4,853 gross (2,675 net) acres in the Prospect. The Company is
the operator.

         A 2-D seismic survey shot and processed originally in 1979 was
reprocessed in 1996 and confirmed the discovery well, which was the K.S. Byrd
Well. The K.S. Byrd Well was completed in June 1997 in the Harper formation from
15,964 feet to 15,988 feet, flowing 5.708 MMCFGD. Initial reserve estimates as
of August 1, 1997 conducted by an independent petroleum engineer gave the well
proved producing reserves of 8.7 BCFG and 34,800 barrels of condensate. Later
reserve estimates as of January 1, 1999 conducted by an independent petroleum
engineer revised the well's proved producing reserves to 12.1 BCFG and 41,500
barrels of condensate. The well began sales of production in September 1997 and,
as of December 31, 1998, was flowing at the rate of 10.4 MMCFGD and 42 BOPD. In
February of 1999 the Howell #1 well was completed and initial tests indicate a
commercial production rate of 21.1 MMCFGD and 19 barrels of condensate per day.
The Fortenberry #1 has just been drilled to total depth with promising
indications but due to mechanical problems is currently being sidetracked for
the lowest 500 feet and logged with 80 net feet of hydrocarbon bearing
reservoir. The well is being completed for production.

          GLANCY

         The Company owns approximately 5,175 gross (4,692 net) acres in the
Glancy Prospect in Copiah County, Mississippi. The Company is the operator.
Glancy Field has produced gas and condensate from the Lower Cretaceous Rodessa
formation on acreage not owned by the Company. The Glancy Prospect is
characterized as a simple anticline structure that formed as a result of a
deep-seated salt pillow. The presence of reservoir quality sandstones at both
the deeper Hosston and Cotton Valley levels has been demonstrated by two well
penetrations, both of which have produced gas and had multiple shows of
hydrocarbons. Early attempts (in 1971) to fracture stimulate one of the test
wells, having an initial production of 3.1 MMCFGD on an extended test from the
Cotton Valley, damaged the formation in the near-wellbore area. The Company
intends to re-enter a deep test well and to apply modern fracture stimulation to
establish commercial production.

         WAUSAU

         The Company owns approximately 1,240 gross (471 net) acres in the
Wausau Prospect in Wayne County, Mississippi (surface to 15,360 feet only). The
Company is the operator. The Company has rights in a 3-D survey acquired by
Compagnie Generale de Geophysiqe over this prospect area. This project is
located on two flanks of a large salt ridge trending northwest to southeast.
Based upon 3-D seismic data, the Cotton Valley appears to be trapped in both a
simple closure and an updip pinchout along the salt ridge flank. The Company
commenced drilling a test well in May 1998 and completed the well in November
1998 as a Cotton Valley discovery. Production commenced in November and was
increased to a rate of over 400 BOPD and 2,000 MCFD with the connection to a gas
sales pipeline in February 1999. The well has three additional shallower Cotton
Valley reservoirs behind pipe.

         SARDIS CHURCH DOME

         The Company owns approximately 4,000 gross (2,835 net) acres in the
Sardis Church Dome Prospect in Copiah County, Mississippi. The Company is the
operator. The Company's drilling objectives are the Paluxy, Hosston and Cotton
Valley sands. The Company anticipates it will sell at least 50% of the working
interest to an industry participant before spudding the test well. This prospect
is an analog to the Oakvale Dome discovery and is located along trend. A nearby
offstructure well has tested significant oil and gas shows in the Hosston
objective section.

         LAHINCH

         The Company owns deep rights under approximately 1,382 gross (1,036
net) acres in the LaHinch Prospect in Duval County, Texas. The Company is the
operator. The objectives for the prospect are sands in the Upper Wilcox
formation. The adjoining operator has drilled an Upper Wilcox test on the same
structure that, if successful, will confirm the Company's prospect and
reclassify it as a proven location. This well reached total depth in April 1999
and is currently being completed. Upon its successful test, the Company will
commence a development program on its acreage.

         OLD OCEAN

         The Company owns leases, options for oil and gas leases and has
contractual rights to earn working interests in approximately 42,889 gross
(10,089 net) acres in the Old Ocean Prospect in Brazoria and Matagorda Counties,
Texas. The Company owns a 37.02% working interest within the Old Ocean Unit and
a 69.23% working interest outside the unit, but within the 3-D area. A 3-D
seismic survey is underway and the Company is the operator of the seismic
survey. The Old Ocean Prospect is the largest Frio gas field in the Gulf Coast,
having produced more than five TCFGE since its discovery in 1934. In excess of
200 wells have been drilled in the Old Ocean field. These reserves have been
produced from four normally pressured reservoirs between 9,500 and 11,000 feet.
The Old Ocean Prospect actually consists of numerous prospects and the main
objective is in the overpressured Frio. Deep well information confirms reservoir
quality sands and scattered production of 45 BCFG in the immediate vicinity.
Precise structural mapping from the 3-D seismic survey will allow accurate
delineation of prospects. Affiliates of EnCap and the Agent and certain of its
clients own a 50% overriding royalty interest in certain of the Company's
properties that make up the Old Ocean Prospect, which interest is convertible
into a participating net profits interest. The Company has the right to buy back
the participating net profits interests and is negotiating such purchase in
exchange for a cash payment to affiliates of EnCap and using Preferred Stock for
the other Old Ocean Lenders.

         OAK HILL FIELD

         The Company owns approximately 793 gross (698 net) acres in the Oak
Hill Field in Gregg and Rusk Counties, Texas. The Company is the operator. This
prospect produces from the Lower Cotton Valley sands at depths of approximately
10,150 to 10,500 feet and from the Upper Cotton Valley sands at depths of
approximately 9,000 to 10,000 feet. The Company has completed a recompletion
program covering six wells and involving up to eleven distinct zones. Six
recompleted zones have been fracture stimulated and have increased the Company's
net production by over 1,100 MCFD. Additionally, the Company expects an increase
of approximately 800 MCFD net production when the original producing interval is
reactivated and the pressures across the zones equalize. There are currently six
producing wells in Oak Hill Field owned by the Company.

         RAYBURN

         The Company owns approximately 3,048 gross (1,068 net) acres and has
options for oil and gas leases on an additional 4,843 gross (3,886 net) acres in
the Rayburn Prospect in Liberty Co., Texas. The Company is the operator. This
prospect is within a 30 square mile 3-D survey acquired in 1998 of which the
Company intends to sell up to 60% to industry partners. The objectives are sands
primarily in the Wilcox, Cockfield and Miocene formations ranging in depth from
2,000 to 16,000 feet.

OIL AND GAS RESERVES

         The following table sets forth information regarding estimated oil and
gas reserve quantities, reserve values and discounted future net revenues as
estimated by the Company's independent engineering consultant, Lenser &
Associates, as of January 1, 1999.

         There are numerous uncertainties inherent in estimating quantities of
proven reserves and projecting future rates of production and timing of
development expenditures. The following reserve information represents estimates
only and should not be construed as being exact.

(1)  Oil production is converted to MCFE at the rate of six MCF of natural gas
     per Bbl of oil, based upon the approximate energy content of natural gas
     and oil.

(2)  Estimated future net revenue represents estimated future gross revenue to
     be generated from the production of proved reserves, net of estimated
     production and future development costs, using prices and costs in effect
     as of January 1, 1999. The amounts shown do not give effect to expenses
     unrelated to property, such as general and administrative expenses, debt
     service and future income tax expense or to depreciation, depletion and
     amortization. The estimates shown do not include amounts dedicated to Shell
     Capital pursuant to the Shell Production Payment (see description of Shell
     Production Payment above), but do include the effect of the EnCap NPI which
     vested on January 1, 1999. The EnCap NPI comprises a 6.25% interest in the

DRILLING ACTIVITY

         The Company participated in one Gross (0.14 Net) dry and three Gross
(1.8383 Net) productive exploratory wells and three Gross (0.25954 Net)
productive development wells during the year ended December 31, 1998. For the
four-month period ended December 31, 1997, the Company drilled one Gross
(0.48500 Net) productive exploratory well, two Gross (1.3575 Net) dry
exploratory wells and three Gross (0.342202 Net) productive development wells.
For the ten months ended August 31, 1997, the Company drilled one Gross (0.14725
Net) productive exploratory well and one Gross (0.20110 Net) dry exploratory
well. The Company is entitled to a working interest in certain additional wells
completed during these time periods when and if those wells pay-out.
Furthermore, the number of Net wells was calculated based-on the Company's
before pay-out working interest and in some cases the Company will have a
greater working interest or is entitled to a working interest in certain wells
completed during these time periods when and if these wells pay-out. In certain
cases, the Company, subsequent to completion, sold the prospect on which certain
of these wells were drilled. As such, while the Company did participate in the
drilling, it does not currently have an interest in all of the productive wells
mentioned above.

         On December 31, 1998, the Company was drilling two Gross (1.2595076
Net) development wells. These wells are step out wells from the Byrd discovery
well at Oakvale Dome Field in Mississippi.

CAEX AND 3-D SEISMIC TECHNOLOGY

         The Company, either directly or through other prospect participants,
uses 3-D seismic data and CAEX technology to collect and analyze geological,
geophysical, engineering, production and other data obtained about potential gas
or oil prospects. The Company uses this technology to correlate density and
sonic characteristics of subsurface formations obtained from 2-D seismic surveys
with like data from similar properties, and uses computer programs and modeling
techniques to determine the likely geological composition of a prospect and
potential locations of hydrocarbons.

         Once all available data has been analyzed to determine the areas with
the highest potential within a prospect area, the Company may conduct 3-D
seismic surveys to enhance and verify the geological interpretation of the
structure, including its location and potential size. The 3-D seismic process
produces a three-dimensional image based upon seismic data obtained from
multiple horizontal and vertical points within a geological formation. The
calculations needed to process such data are made possible by computer programs
and advanced computer hardware.

         While large oil companies have used 3-D seismic data and CAEX
technologies for approximately 20 years, these methods were not affordable by
smaller, independent oil and gas companies until more recently, when improved
data acquisition equipment and techniques and computer technology became
available at reduced costs. The Company believes that its use of 3-D seismic
data and CAEX technology may provide it with certain advantages in the
exploration process over those companies that do not use this technology. These
advantages include better delineation of the subsurface, which can reduce
exploration risks and help optimize well locations in productive reservoirs. The
Company believes these advantages can be readily validated based upon general
industry experience. Because computer modeling generally provides clearer and
more accurate projected images of geological formations, the Company believes it
is better able to identify potential locations of hydrocarbon accumulations and
the desirable locations for wellbores. However, the Company has not used the
technology extensively enough to arrive at any conclusion regarding the
Company's ability to interpret and use the information developed from the
technology.

CUSTOMERS

         During the year ended December 31, 1998, H&N Gas Ltd. "H&N Gas" and
Tejas Gas Marketing Co. accounted for approximately 51% and 24%, respectively of
the Company's total revenue. For the four month period ended December 31, 1997,
H&N Gas and KCS Resources, Inc. ("KCS") accounted for 75% and 10%, respectively,
of the Company's total revenue. For the ten months ended August 31, 1997, KCS,
Samedan Oil Corporation and Energy Operating Limited Partnership accounted for
50%, 30% and 15%, respectively, of the Company's total revenue. No other
purchasers accounted for more than 10% of the Company's total revenue in the
periods indicated above. The Company does not believe the loss of any existing
purchaser would have a material adverse effect on the Company.

MARKETING

         The Company markets its natural gas and oil through monthly spot sales.
Because sales made under spot sales contracts result in fluctuating revenues to
the Company depending upon the market price of oil and gas, the Company from
time to time enters into various forward contracts covering a portion of its
production to minimize the fluctuations and the effect of price declines. Under
the terms of the term production payment with Shell Capital, the Company markets
its natural gas through Coral Energy Resources, L.P. ("Coral") whereby Coral
markets at both fixed and floating prices.

COMPETITION

         The oil and gas industry is highly competitive in all of its phases.
The Company encounters strong competition from other oil and gas companies in
all areas of its operations, including the acquisition of exploratory and
producing properties, the permitting and conducting of seismic surveys and the
marketing of oil and gas. Many of these competitors possess greater financial,
technical and other resources than the Company. Competition for the acquisition
of producing properties is affected by the amount of funds available to the
Company, information about producing properties available to the Company and any
standards the Company establishes from time to time for the minimum projected
return on investment. Competition also may be presented by alternative fuel
sources, including heating oil and other fossil fuels. There has been increased
competition for lower risk development opportunities and for available sources
of financing. In addition, the marketing and sale of natural gas and processed
gas are competitive. Because the primary markets for natural gas liquids are
refineries, petrochemical plants and fuel distributors, prices generally are set
by or in competition with the prices for refined products in the petrochemical,
fuel and motor gasoline markets.

REGULATION

         GENERAL

         The oil and gas industry is extensively regulated by federal, state and
local authorities. In particular, oil and gas production operations and
economics are affected by environmental protection statutes, tax statutes and
other laws, rules and regulations relating to the petroleum industry, as well as
changes in such laws, changing rules and regulations and the interpretations and
applications of such laws, rules and regulations. Oil and gas industry
legislation and agency regulation are under constant review for amendment and
expansion for a variety of political, economic and other reasons. Numerous
regulatory authorities, and federal, state and local governments issue rules and
regulations binding on the oil and gas industry, some of which carry substantial
penalties for failure to comply. The regulatory burden on the oil and gas
industry increases the Company's cost of doing business and, consequently,
affects its profitability. The Company believes it is in compliance with all
federal, state and local laws, regulations and orders applicable to the Company
and its properties and operations, the violation of which would have a material
adverse effect on the Company or its financial condition.

         SEISMIC PERMITS

         Current law in Louisiana requires permits from owners of at least an
undivided 80% interest in each tract over which the Company intends to conduct
seismic surveys. As a result, the Company may not be able to conduct seismic
surveys covering its entire area of interest in that state. Moreover, 3-D
seismic surveys typically are conducted from various locations both inside and
outside the area of interest to obtain the most detailed data of the


                                      52

<PAGE>

geological features within the area. To the extent that the Company is unable
to obtain permits to access locations to conduct the seismic surveys, the
data obtained may not be as detailed as might otherwise be available. In
addition, a recent decision of a federal court in Louisiana casts doubt on
traditional seismic permitting practices, which decision, in some instances,
could lead to the surface owner claiming ownership of the data.

         EXPLORATION AND PRODUCTION

         The Company's operations are subject to various regulations at the
federal, state and local levels. Such regulations include (i) requiring permits
for the drilling of wells; (ii) maintaining bonding requirements to drill or
operate wells; and (iii) regulating the location of wells, the method of
drilling and casing wells, the surface use and restoration of properties upon
which wells are drilled, the plugging and abandoning of wells and the disposal
of fluids used in connection with well operations. The Company's operations also
are subject to various conservation regulations. These include the regulation of
the size of drilling and spacing units, the density of wells that may be
drilled, and the unitization or pooling of oil and gas properties. In addition,
state conservation laws establish maximum rates of production from oil and gas
wells, generally prohibiting the venting or flaring of gas, and impose certain
requirements regarding the ratability of production. The effect of these
regulations is to limit the amount of oil and gas the Company can produce from
its wells and to limit the number of wells or the locations at which the Company
can drill.

         NATURAL GAS MARKETING, GATHERING AND TRANSPORTATION

         Federal legislation and regulatory controls in the United States have
historically affected the price of the natural gas produced by the Company and
the manner in which such production is marketed. The transportation and resale
of natural gas in interstate commerce are regulated by the Federal Energy
Regulatory Commission (the "FERC") pursuant to the Natural Gas Act and the
Natural Gas Policy Act of 1978 (the "NGPA"). Sales of the Company's natural gas
currently are made at market prices, subject to applicable contract provisions
and are not subject to federal or state price control. The FERC's jurisdiction
over natural gas transportation was unaffected by the Decontrol Act.

         The FERC also regulates interstate natural gas transportation rates and
service conditions, which affect the marketing of natural gas produced by the
Company, as well as the revenues received by the Company for sales of such
natural gas. Since the latter part of 1985, the FERC has endeavored to make
interstate natural gas transportation more accessible to gas buyers and sellers
on an open and nondiscriminatory basis. The FERC's efforts have significantly
altered the marketing and transportation of natural gas. Commencing in April
1992, the FERC issued Order Nos. 636, 636-A, 636-B and 636-C (collectively,
"Order No. 636"), which, among other things, required interstate pipelines to
"restructure" their services to provide transportation separate or "unbundled"
from the pipelines' sales of gas. Also, Order No. 636 requires interstate
pipelines to provide open-access transportation on a nondiscriminatory basis
that is equal for all natural gas shippers. Order No. 636 has been implemented
through decisions and negotiated settlements in individual pipeline services
restructuring proceedings. In many instances, the result of Order No. 636 and
related initiatives has been to substantially reduce or eliminate the interstate
pipelines' traditional role as wholesalers of natural gas, and has substantially
increased competition and volatility in natural gas markets. The FERC has issued
final orders in virtually all Order No. 636 pipeline restructuring proceedings.
In July 1996, the United States Court of Appeals for the District of Columbia
Circuit largely upheld Order No. 636 and remanded certain issues for further
explanation or clarification. Numerous petitions for review of the individual
pipeline restructuring orders are currently pending in that court. The issues
remanded for further action do not appear to materially affect the Company.
Proceedings on the remanded issues are currently ongoing before the FERC
following its issuance of Order No. 636-C in February 1997. Although it is
difficult to predict when all appeals of pipeline restructuring orders will be
completed or their impact on the Company, the Company does not believe that it
will be affected by the restructuring rule and orders any differently than other
natural gas producers and marketers with which it competes.

         Although Order No. 636 does not regulate natural gas production
operations, the FERC has stated that Order No. 636 is intended to foster
increased competition within all phases of the natural gas industry. It is
unclear what impact, if any, increased competition within the natural gas
industry under Order No. 636 will have on the Company and its natural gas
marketing efforts. Although Order No. 636 could provide the Company with
additional market access and more fairly applied transportation service rates,
terms and conditions, it could also subject the Company to more restrictive
pipeline imbalance tolerances and greater penalties for violation of those
tolerances.


                                      53

<PAGE>

The Company does not believe, however, that it will be affected by any action
taken with respect to Order No. 636 materially differently than other natural
gas producers and marketers with which it competes.

         The FERC has recently announced its intention to re-examine certain of
its transportation-related policies, including the appropriate manner for
setting rates for new interstate pipeline construction, the manner in which
interstate pipeline shippers may release interstate pipeline capacity under
Order No. 636 for resale in the secondary market, the price that shippers can
charge for their released capacity, and the use of negotiated and market-based
rates and terms and conditions for interstate gas transmission. Several
pipelines have obtained FERC authorization to charge negotiated rates as an
alternative to traditional, cost-of-service rate making methodology. In February
1997, the FERC announced a broad inquiry into issues facing the natural gas
industry to assist the FERC in establishing regulatory goals and priorities in
the post-Order No. 636 environment. In December 1997, the FERC requested
comments on the financial outlook of the natural gas pipeline industry,
including among other matters, whether the FERC's current rate making policies
are suitable in the current industry environment. In April 1998, the FERC issued
a new rule to further standardize pipeline transaction tariffs that, as the
result of newly standardized provisions regarding firm intra day transportation
nominations, could adversely affect the reliability of scheduled interruptible
transportation service on some pipelines. While any resulting FERC action would
affect the Company only indirectly, any new rules and policy statements may have
the effect of enhancing competition in natural gas markets.

         Additional proposals and proceedings that might affect the natural gas
industry are considered from time to time by Congress, the FERC and state
regulatory bodies. The Company cannot predict when or if any such proposals
might become effective, or their effect, if any, on the operations of the
Company. The natural gas industry historically has been very heavily regulated;
therefore, there is no assurance that the less stringent regulatory approach
recently pursued by the FERC and Congress will continue indefinitely. The
regulatory burden on the oil and natural gas industry increases the Company's
cost of doing business and, consequently, affects its profitability and cash
flow. In as much as such laws and regulations are frequently expanded, amended
or reinterpreted, the Company is unable to predict the future cost or impact of
complying with such regulations.

         LOUISIANA LEGISLATION

         The Louisiana legislature passed Act 404 in 1993, which permits a party
transferring an oil field site to establish a site-specific trust account for
such oil field. If the site-specific trust account is established in accordance
with the requirements of the statute, the party transferring the oil field site
may not thereafter be held liable by the state for any site restoration costs or
actions associated with the transferred oil field site. The parties to a
transfer may elect not to establish a site-specific trust account. However, in
the absence of such an account, the transferring party will continue to have
liability for the costs of restoration of the site. If the parties to a transfer
elect to establish a site-specific trust account pursuant to the statute, the
Louisiana Department of Natural Resources (the "DNR") requires an oil field site
restoration assessment to be made at the time of the transfer or within one year
thereafter, to determine the site restoration requirements existing at the time
of transfer. Based upon the site restoration assessment, the parties to the
transfer must propose to the DNR a funding schedule for the site-specific trust
account, providing for some contribution to the account at the time of transfer
and at least quarterly payment thereafter. If the DNR approves the establishment
and funding of the site-specific trust account, the purchaser will thereafter be
the responsible party to the state, except that the failure of a transferring
party to make a good faith disclosure of all oil field site conditions existing
at the time of the transfer will render that party liable for the costs of
restoration of such undisclosed conditions in excess of the balance of the
site-specific trust fund.

         OIL SALES AND TRANSPORTATION RATES

         The FERC also regulates rates and service conditions for interstate
transportation of crude oil, liquids and condensate, which can affect the amount
the Company receives from the sale of these products. Rates for such
transportation are generally subject to an indexing system under which rates may
be increased as long as they do not exceed an index rate that is tied to
inflation. Over time, this indexing system could have the effect of increasing
the cost of transporting crude oil, liquids and condensate by pipeline. Sales of
crude oil, condensate and gas liquids by the Company are not regulated and are
made at market prices. The price the Company receives from the sale of these
products is affected by the cost of transporting the products to market.


                                      54

         ENVIRONMENTAL MATTERS

         The Company's oil and natural gas exploration, development and
production operations are subject to stringent federal, state and local laws
governing the discharge of materials into the environment or otherwise relating
to environmental protection. Numerous governmental agencies, such as the
Environmental Protection Agency (the "EPA"), issue regulations to implement and
enforce such laws, which often require difficult and costly compliance measures
that carry substantial civil and criminal penalties for failure to comply. These
laws and regulations may require the acquisition of a permit before drilling
commences, restrict the types, quantities and concentrations of various
substances that can be released into the environment in connection with drilling
and production activities, limit or prohibit drilling activities on certain
lands lying within wilderness, wetlands, ecologically sensitive and other
protected areas, require some form of remedial action to prevent pollution from
former operations, such as plugging abandoning wells, and impose substantial
liabilities for pollution resulting from the Company's operations. In addition,
these laws, rules and regulations may restrict the rate of oil and natural gas
production below the rate that would otherwise exist. The regulatory burden on
the oil and gas industry increases the cost of doing business and consequently
affects its profitability. Changes in environmental laws and regulations occur
frequently, and any changes that result in more stringent and costly waste
handling, disposal or cleanup requirements could adversely affect the Company's
operations and financial position, as well as those of the oil and gas industry
in general. While management believes that the Company is in substantial
compliance with current applicable environmental laws and regulations and the
Company has not experienced any material adverse effect from compliance with
these environmental requirements, there is no assurance that this will continue
in the future.

         The primary environmental statutory and regulatory programs that affect
the Company's operations include the following:

         The Comprehensive Environmental Response, Compensation and Liability
Act, as amended ("CERCLA") also known as "Superfund", imposes liability without
regard to fault or the legality of the original conduct, on certain classes of
persons who are considered to be responsible for the release of a "hazardous
substance" into the environment. These persons include (i) the current owner and
operator of a facility from which hazardous substances are released, (ii) owners
and operators of the facility at the time the disposal of hazardous substances
took place, (iii) generators of hazardous substances who arranged for the
disposal or treatment at or transportation to such facility of hazardous
substances and (iv) transporters of hazardous substances to disposal or
treatment facilities selected by them.

         Under CERCLA, such persons may be subject to joint and several
liability for the costs of cleaning up the hazardous substances that have been
released into the environment, for damages to natural resources and for the
costs of certain health studies, and it is not uncommon for neighboring
landowners and other third parties to file claims for personal injury and
property damage allegedly caused by the release of hazardous substances or other
pollutants into the environment. Furthermore, although petroleum, including
crude oil and natural gas, is exempt from CERCLA, at least two courts have ruled
that certain wastes associated with the production of crude oil may be
classified as "hazardous substances" under CERCLA, and thus such wastes may
become subject to liability and regulation under CERCLA. Regulatory programs
aimed at remediation of environmental releases could have a similar impact on
the Company.

         The Federal Water Pollution Control Act of 1972 ("FWPCA") as amended,
also known as the Clean Water Act (the "CWA"), imposes restrictions and strict
controls regarding the discharge of pollutants, including produced waters and
other oil and gas wastes, into waters of the United States (as defined in the
CWA). The discharge of pollutants into regulated waters is prohibited, except in
accordance with the terms of a permit issued by the EPA or the state. These
proscriptions also prohibit certain activities in wetlands unless authorized by
a permit issued by the U.S. Army Corps of Engineers. Sanctions for unauthorized
discharges include administrative, civil and criminal penalties, as well as
injunctive relief.

         The Oil Pollution Act of 1990 (the "OPA") amends certain provisions of
the CWA, and other statutes as they pertain to the prevention of and response to
spills or discharges of hazardous substances or oil into navigable waters. Under
the OPA, a person owning or operating a facility or equipment (including land
drilling equipment) from which there is a discharge or threat of a discharge of
oil into or upon navigable waters or adjoining shorelines is liable, regardless
of fault, as a "responsible party" for removal costs and damages. Federal law
impose strict, joint and several liability on facility owners for containment
and clean-up cost and certain other damages, including natural resource damages,
arising from a spill.


                                      55

<PAGE>

         The EPA is also authorized to seek preliminary and permanent injunctive
relief and, in certain cases, criminal penalties and fines. State laws governing
the control of water pollution also provide varying civil and criminal penalties
and liabilities in the case of releases of petroleum or its derivatives into
surface waters or into the ground. If a discharge occurs at a well site at which
the Company is conducting production operations, the Company may be exposed to
claims that it is liable under the OPA, the CWA or similar state laws.

         The Resource Conservation and Recovery Act ("RCRA"), as amended,
generally does not regulate most wastes generated by the exploration and
production of oil and gas. RCRA specifically excludes from the definition of
hazardous waste "drilling fluids, produced waters, and other wastes associated
with the exploration, development, or production of crude oil, natural gas or
geothermal energy." However, these wastes may be regulated by the EPA or state
agencies as solid waste. Moreover, ordinary industrial wastes, such as paint
wastes, waste solvents, laboratory wastes, and waste compressor oils, may be
regulated as hazardous waste. Pipelines used to transfer oil and gas may also
generate some hazardous wastes. Although the costs of managing solid and
hazardous waste may be significant, the Company does not expect to experience
more burdensome costs than similarly situated companies involved in oil and gas
exploration and production.

TITLE TO PROPERTIES

         Title to properties is subject to royalty, overriding royalty, carried
working, net profits, working and other similar interests and contractual
arrangements customary in the oil and gas industry, liens for current taxes not
yet due and other encumbrances. As is customary in the industry in the case of
undeveloped properties, little investigation of record title is made at the time
of acquisition (other than a preliminary review of local records).
Investigations, including a title opinion covering the drill site by local
counsel, generally are made before commencement of drilling operations. With
respect to acquisitions of producing properties, it is customary to review title
opinions, review engineering reserve reports and conduct environmental and
operational reviews before the closing of the purchase.

OPERATING HAZARDS AND INSURANCE

         The oil and gas business involves a variety of operating risks,
including the risk of fire, explosions, blow-outs, pipe failure, abnormally
pressured formations, and environmental hazards such as oil spills, gas leaks,
ruptures or discharges of toxic gases, the occurrence of any of which could
result in substantial losses to the Company due to injury or loss of life,
severe damage to or destruction of property, natural resources and equipment,
pollution or other environmental damage, cleanup responsibilities, regulatory
investigation and penalties and suspension of operations.

         The Company maintains an oil and gas lease operator insurance policy
that insures the Company against certain sudden and accidental risks associated
with drilling, completing and operating its wells. In addition, we require
certain parties conducting operations for us to maintain general comprehensive
liability policies with contractual coverage to support the contractors'
obligations to indemnify and defend us in certain circumstances. There can be no
assurance that this insurance will be adequate to cover any losses or exposure
to liability. The Company also carries comprehensive general liability policies
and an umbrella policy. Although the Company believes that the amount of
coverage it maintains is customary in the industry, it does not provide complete
coverage against all operating risks. An uninsured or partially insured claim,
if successful and of sufficient magnitude, could have a material adverse effect
on the Company and its financial condition. If the Company experiences
significant claims or losses, the Company's insurance premiums could be
increased, which may adversely affect the Company and its financial condition,
or limit the ability of the Company to obtain coverage. Any difficulty in
obtaining coverage may impair the Company's ability to engage in its business
activities.

LEGAL PROCEEDINGS

         The Company is involved in routine litigation arising in the ordinary
course of business. Management believes that the results of each proceedings,
individually and in the aggregate, will not have a material adverse effect on
the Company's financial position or results of operations.

FACILITIES

         The Company maintains approximately 25,100 square feet of office space
in Houston, Texas, which is leased at an annual rent of $396,187. The lease
expires January 31, 2003. The Company believes it will be able to renew the
lease on acceptable terms, and is currently offering up to half of the space for
sublease.

EMPLOYEES

         The Company terminated Mr. LaFlure's employment without cause effective

1997. The new stock option agreement dated February 15, 1999 is for 500,000
shares of Common Stock at an exercise price of Cdn.$0.53 per share. The
remaining amounts due under the settlement agreement payable on January 15,
2001, shall be reduced by the difference between the option price under the new
option agreement for 500,000 shares of Common Stock and the 500,000 option
shares as of the date the payment of the balance of the agreed amounts. All cash
payments payable to Mr. LaFlure shall be reduced by applicable federal, state of
local withholding taxes. The Company also agreed that at its sole cost and

disability or death at any time before the expiration thereof, then the Company
must pay to Mr. Herlin the remaining amount of salary accrued or otherwise to be
paid throughout the remainder of the term of the agreement; provided that the
remaining amount may be no less than 12 months of Mr. Herlin's salary. If such
termination is due to a change of control of the Company, the minimum remaining
amount must be equal to 24 months of Mr. Herlin's salary.

         In the event of termination of Mr. Herlin for cause, such agreement
terminates immediately and the Company's sole remaining obligation is to pay any
amounts accrued thereunder through the date of termination.

         On December 16, 1998, the Company entered into an agreement with EnCap,
the largest secured creditor of the Company, that should Mr. Tomlinson's
employment be terminated, except for cause, following certain events, then EnCap

severance, enter into a consulting agreement with a three year term providing

RELATED PARTY TRANSACTIONS

         ENCAP CREDIT FACILITY

         In 1997, the Company entered into a $20.0 million credit agreement with
EnCap consisting of an Original Note for $12.0 million and a Supplemental Note
for $8.0 million. The Original Note bears interest at 10.0% per annum, and was
due, with accrued interest, in December 1998. The Supplemental Note, which has
been repaid in full, bore interest at 10.0% per annum until July 1, 1998 and at
18.0% per annum thereafter. Under the terms of the Supplemental Note, EnCap was
issued warrants for the purchase of 1.5 million shares of common stock at an
exercise price of $1.28 per share. The Original Note is secured by a first lien
on the properties acquired and a second lien on certain other properties. The
Original Note has been guaranteed by Mr. Tomlinson, Calibre and certain of
Calibre's affiliates.

         Under the Original Note, the Company agreed to convey to EnCap a 25.0%
net profit interest from the properties acquired with the proceeds of the
borrowing. EnCap also required Slattery Trust, Texstar Holdings and certain of
the Company's shareholders to enter into a Put/Call Agreement pursuant to which
those shareholders, under certain conditions, have the right to obtain or "call"
the EnCap NPI in exchange for 1.5 million shares of the Company's common stock.
The Put/Call Agreement also gives EnCap the right, under certain conditions, to
sell, or put, portions of the EnCap NPI to the shareholders for $1.5 million or
3.5 million shares of the Company's common stock as of December 31, 1998 or
March 31, 1999, respectively. The shareholders' rights and obligations under the
Put/Call Agreement have been transferred to the Company.

         STANFORD ENERGY DEBENTURE

         In August 1997, Stanford Energy issued the Company an unsecured
convertible debenture in the principal amount of Cdn.$200,000. The debenture
bore interest at a rate of 8.0% per annum, payable quarterly. The debenture was
repaid on August 6, 1997.

         ADVANCES TO CALIBRE EQUADOR

         In the Spring of 1997, the Company and Slattery Trust, Starbucks Trust,
Mr. Grabois, Mr. Novak and James Alexander formed Calibre Ecuador, Inc. to
develop certain oil and gas prospects in Ecuador. The Company owned 50% of the
outstanding common stock of Calibre Ecuador and the other parties collectively
owned the other 50%. The development of the prospects required enactment of
certain enabling legislation that would permit non-Ecuador citizens to own oil
and gas properties in Ecuador. Pending the enactment of such legislation, the
Company advanced funds to Calibre Ecuador to generate the prospect, all rights
to were contributed to Calibre Ecuador by the parties other than the Company. As
of December 31, 1997 the Company had written off advances totaling $402,192 made
to Calibre Ecuador. Calibre Ecuador had no means with which to repay the
advances. The advances were non-interest bearing and due upon demand. Due to the
write-off, the Company obtained rights to substantially all of Calibre Equador's
common stock.

         In November, 1998, the Company entered into a Participation Agreement
with Burlington Resources International Inc. to develop the gas fields in
Ecuador. The Company and Burlington have participation interests of 25% and 75%,
respectively. Burlington has indicated it might not renew the agreement and the
action could have an


                                       63

<PAGE>

impact on the Company's ability to maintain an interest in the region.
However, the Company would retain a 25% interest in any project related to
the subject area pursued by Burlington for one year.

         CALIBRE TRANSACTIONS

         In December 1997, the Company advanced funds to Calibre Oil & Gas, Inc.
Net advances to Calibre Oil & Gas, Inc. totaled $1,768,772 at December 31, 1997.
The advances bore no interest and were due upon demand.

         On April 22, 1998, in a single transaction, the Company acquired all of
the outstanding shares of Calibre Oil & Gas, Inc. from Calibre and certain oil
and gas properties owned by the Slattery Trust, the Starbucks Trust, Todd
Grabois, Robert Novak, Prentis B. Tomlinson, Jr., and Calibre Oil & Gas, Inc.
The shares of Calibre Oil & Gas, Inc. were valued at $3,820,713 and were paid
for through the issuance to Calibre of 1,927,426 shares of common stock of the
Company valued at Cdn. $2.80 per share. The total purchase price for the oil and
gas properties acquired from the other parties was $2,261,000, paid $261,000 in
cash and $2,000,000 in promissory notes issued by Texstar Petroleum Inc. in
differing amounts to each party. These notes were guaranteed by the Company,
paid 10% annual interest and were to be repaid in two equal installments due on
April 1, 1998 and September 1, 1998. The purchase price was to be adjusted by a
credit for proceeds from production attributable to each property through
January 31, 1998.

         In connection with the acquisition of the oil and gas properties and
shares of Calibre Oil & Gas, Inc., $1.45 million of the advances to Calibre Oil
& Gas, Inc. were reclassified as an assumption of payables and the remaining
$318,772 was written off as a bad debt. Calibre Oil & Gas, Inc. was subsequently
merged into the Company and ceased to exist on January 7, 1999.

         LASCO ACQUISITION

         In January 1998, and effective on December 1, 1997, the Company
acquired proved reserves in Texas and Louisiana from Lasco for 2.57 million
shares of Common Stock and 12.0 million shares of the Company's Series 1
preferred stock. In December 1998, the Company reconveyed a portion of those
interests to Lasco in exchange for approximately 2.5 million shares of the
Company's Series 1 preferred stock.

         STARBUCKS NOTE

         On January 1, 1998, the Company loaned Starbucks Trust $2.5 million
pursuant to a promissory note due December 31, 1998 that bears interest at 9.0%
per annum. Starbucks Trust is a grantor trust with the sole beneficiary and
trustee being Heather Tomlinson, Prentis Tomlinson's spouse. Total advances and
accrued interest under the note are $2.9 million as of March 31, 1999. Funds
that the Company lent to Starbucks Trust were a portion of the proceeds the
Company received from the Offering of the Notes that are being exchanged in the
Offering. The loan was intended to (i) give the Company a greater return on
investment than it was receiving at the time; (ii) acquire shares of the
Company's common stock in the open market to support the public trading price;
and (iii) acquire Common Stock that was reconveyed by Starbucks Trust to certain
of the Company's lenders in an effort to deliver to those lenders freely
tradeable Company common stock. The entire principal interest outstanding under
the note remains due and payable and is carried on the Company's books as an
account receivable; however, Starbucks Trust lost money on the securities
transactions it made with the proceeds of the loan and currently is unable to
repay the loan.

         Starbucks has claimed and requested credits, for expenses incurred on
behalf of the Company, against the amounts owed under the note of Cdn. $740,240.
Separately, and pursuant to the terms of the Starbucks Trust Acquisition
Agreement, the Company owes the Starbucks Trust $1,283,462 inclusive of accrued
interest as of December 31, 1998. Pursuant to the Calibre Acquisition Agreement,
as of December 31, 1998, the Company further owes the Starbucks Trust $213,918
and Prentis Tomlinson $1,588,489 inclusive of accrued interest. On December 28,
1998, as part of the Shell transaction, the above parties and Texstar Holdings,
LLC and Security Oil, LLC signed a standstill agreement wherein all parties
mutually deferred payments and further agreed not to pursue collection of any
amounts until the Termination Date of the Shell transaction and to toll the
applicable statutes of limitations related to claims arising from any such
amounts until the earlier of the Termination Date or December 31, 2003.

         STARBUCKS ACQUISITION

         In July 1998, the Company entered into the Starbucks Acquisition
pursuant to which the Company acquired certain proved non-producing oil and gas
properties in Mississippi, Texas and Louisiana from Starbucks Trust for $2.33
million and 600,000 shares of Common Stock. The purchase is subject to approval
by the Vancouver Stock Exchange and is subject to certain post-closing
adjustments relating to purchase value. The purchase value is guaranteed and
secured by 2.1 million shares of Common Stock owned by the Starbucks Trust.

         OTHER RELATED PARTY TRANSACTIONS

September 1998. Thereafter, the agreement continues in effect from year to year
unless terminated by either party upon 60 days' written notice. During the last
fiscal year the Company paid Chase Management Cdn.$60,000 and for the remaining
term of the agreement, the Company will pay Chase Management Cdn.$5,000 per

                          DESCRIPTION OF CAPITAL STOCK

         The Company's Certificate of Incorporation provides for authorized
capital stock of 400,000,000 shares, consisting of 300,000,000 shares of Common
Stock, par value $0.01 per share and 100,000,000 shares of Preferred Stock, par
value $1.00 per share. The following summary description of the capital stock is

the attached Certificate of Designation. As of May 31, 1999, 33,727,724 shares
of Common Stock and 9,488,140 Class A, Series I Preferred Shares
(non-convertible 10% dividend) were issued and outstanding.

COMMON STOCK

         Holders of Common Stock are entitled to one vote per share in the
election of directors and on all other matters on which stockholders are
entitled or permitted to vote. Holders of Common Stock are not entitled to
cumulative voting rights. Therefore, holders of a majority of the shares voting
for the election of directors can elect all the directors. Subject to the terms
of any outstanding series of preferred stock, the holders of Common Stock are
entitled to dividends in such amounts and at such times as may be declared by
our board of directors out of funds legally available therefor. Upon liquidation
or dissolution, holders of Common Stock are entitled to share ratably in all net
assets available for distribution to stockholders after payment of any
liquidation preferences to holders of preferred stock. Holders of Common Stock
have no redemption, conversion or preemptive rights.

PREFERRED STOCK

         The board of directors has the authority to cause the Company to issue
up to the authorized number of shares of preferred stock in one or more series,
to designate the number of shares constituting any series, and to fix the
rights, preferences, privileges and restrictions thereof, including dividend
rights, voting rights, redemption and conversion rights and liquidation
preferences of such series, without further action by the stockholders. The
issuance of preferred stock with voting and conversion rights may adversely
affect the voting power of the holders of the common stock.

         SERIES I PREFERRED STOCK

         On March 6, 1998, the Company's board of directors authorized the
issuance of 12,000,000 shares of Series I preferred stock. Set forth below is a

                                       65

<PAGE>

                  DIVIDENDS. The shares of Series I preferred stock are entitled
         to dividends at the Designated Rate (as defined below), to be paid in
         cash quarterly on March 31, June 30, September 30, and December 31 of
         each year and are cumulative whether or not declared or whether or not
         there are funds legally available to pay the dividend on the aggregate
         price paid or deemed to be paid (the "Purchase Price") for the shares.
         Such dividends will be prior and in preference to any declaration or
         payment of any dividends paid on Junior Stock. The Designated Rate is
         10% per annum, but upon the occurrence or continuance of a Voting Event
         (as defined below), the rate shall be 14% per annum. For the first
         eight quarters dividends are due, the board of directors may elect to
         make payment in Common Stock.

                  LIQUIDATION PREFERENCE. In the event of any liquidation,
         dissolution, or winding up, voluntary or involuntary, the shares of
         Series I preferred stock are entitled to preference to the Junior Stock
         of a cash amount equal to the Purchase Price plus dividends accumulated
         but not paid (the "Liquidation Amount"). A consolidation or merger of
         the Company with or into any other entity, or a sale or transfer in a
         single transaction or a series of related transactions of all or
         substantially all of the Company's assets, shall be deemed to be a
         liquidation for purposes hereof.

                  OPTIONAL REDEMPTION. Upon five business days advance notice,
         the Company has the option to redeem any or all of the shares of Series
         I preferred stock at any time at a cash redemption price per share
         equal to the Liquidated Amount divided by the number of shares of
         Series I preferred stock originally issued.

                  MANDATORY REDEMPTION. If the Series I preferred stock has not
         been redeemed within five years of being issued, the Company is
         required to redeem the shares at a cash redemption price per share
         equal to the Liquidation Amount divided by the number of shares of
         Series I preferred stock originally issued. If a qualified public
         offering of at least $25 million has not been completed by January 23,
         2001, the Series I preferred stock may be put back to the Company for
         cash redemption. The holder of the Series I preferred stock has agreed
         to waive this put redemption right contingent upon the completion of
         the Offering. Redemption of the Series II Preferred Stock will require
         either the redemption for cash of the Series I preferred stock or
         consent of the holders of the Series I preferred stock.

                  VOTING RIGHTS. The Series I preferred stock have no voting
         rights, except as set forth below. Upon the occurrence of a Voting
         Event, the Series I shareholders shall be, voting as a single class,
         entitled to elect (i) two directors at any time there are more than
         1,200,000 Series I shares outstanding, or (ii) one director if there
         are 1,200,000 Series I shares or less. Any director so elected shall
         serve until all Voting Events have ceased to be continuing. Voting
         Events include: (i) the failure to pay at least two dividends on the
         Series I shares as they become due and payable; (ii) the failure to
         redeem the Series I shares when required for the put redemption, (iii)
         the failure to redeem the Series I preferred stock when required for
         the mandatory redemption, (iv) bankruptcy, insolvency, appointment of a
         receiver, liquidator or similar official, monetary judgments in excess
         of $500,000 not covered by insurance, or writs or warrants of
         attachment or similar process against all or a substantial part of our
         assets.

         SERIES II PREFERRED STOCK

         See "Summary - the Offering" and "Comparison of the Notes and Preferred
Stock" for a summary of certain terms of the Preferred Stock. The Certificate of
Designation is attached hereto as Appendix A.


PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND DELAWARE LAW

         The Company's Certificate of Incorporation authorizes the board of
directors, without stockholder approval, to establish and to issue shares of one
or more series of preferred stock, each such series having such voting rights,
dividend rates, liquidation, redemption, conversion and other rights as may be
fixed by the board. The Company's Bylaws direct that special meetings of the
stockholders may only be called by a majority of the members of the board of
directors, the chairman of the board of directors, the president or the holders
of not less than 30% of the total voting power of all shares of its capital
stock entitled to vote in the election of directors. The Bylaws further provide
that stockholders' nominations to the board of directors and other stockholder
business proposed to be


                                       66

<PAGE>

transaction at stockholder meetings must be timely received by the Company in
a proper written form which meets the prescribed content requirements.

         The above provisions may have the effect of deterring certain tender
offers or hostile takeovers or may delay or prevent changes in control of our
management.

LIMITATION OF DIRECTOR LIABILITY

         Section 102(b)(7) of the Delaware General Corporation Law ("Section
102(b)") authorizes corporations to limit or eliminate the personal liability of
directors to corporations and their stockholders for monetary damages for breach
of directors' fiduciary duty of care. Although Section 102(b) does not change
directors' duty of care, it enables corporations to limit available relief to
equitable remedies such as injunction or rescission. The Company's Certificate
of Incorporation limits the liability of its directors or its stockholders (in
their capacity as directors but not in their capacity as officers) to the
fullest extent permitted by Section 102(b). Specifically, the Company's
directors will not be personally liable for monetary damages for breach of a
director's fiduciary duty as a director, except for liability: (i) for any
breach of the director's duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or that involve intentional,
misconduct or a knowing violation of law, (iii) for unlawful payments of
dividends or unlawful stock repurchases or redemptions as provided in Section
174 of the Delaware General Corporation Law, or (iv) for any transaction from
which the director derived an improper personal benefit.

INDEMNIFICATION

         To the maximum extent permitted by law, the Certificate of
Incorporation and Bylaws provide for mandatory indemnification of directors, and
permit indemnification of the Company's officers, employees and agents against
all expense, liability and loss to which they may become subject or which they
may incur as a result of being or having been a director, officer, employee or
agent. In addition, the Company must advance or reimburse directors, and may
advance or reimburse officers, employees and agents, for expenses incurred by
them in connection with indemnifiable claims.

DELAWARE ANTI-TAKEOVER LAW

         Section 203 of the Delaware General Corporation Law ("Section 203")
generally provides that a stockholder acquiring more than 15% of the outstanding
voting stock of a corporation subject to the statute (an "Interested
Stockholder") but less than 85% of such stock may not engage in certain
"Business Combinations" with the corporation for a period of three years after
the date on which the stockholder became an Interested Stockholder unless (i)
before such date, the corporation's board of directors approved either the
Business Combination or the transaction in which the stockholder became an
Interested Stockholder, or (ii) the Business Combination is approved by the
corporation's board of directors and authorized at a stockholders' meeting by a
vote of at least two-thirds of the corporation's outstanding voting stock not
owned by the Interested Stockholder. Under Section 203, these restrictions will
not apply to certain Business Combinations proposed by an Interested Stockholder
following the earlier of the announcement or notification of one of certain
extraordinary transactions involving the corporation and a person who was not an
Interested Stockholder during the previous three years or who became an
Interested Stockholder with the approval of the corporation's board of
directors, if such extraordinary transaction is approved or not opposed by a
majority of the directors who were directors prior to any person becoming an
Interested Stockholder during the previous three years or were recommended for
election or elected to succeed such directors by a majority of such directors.

         Section 203 defines the term "Business Combination" to encompass a wide
variety of transactions with or caused by an Interested Stockholder, including
transactions in which the Interested Stockholder receives or could receive a
benefit on other than a pro rata basis with other stockholders, such as mergers,
certain asset sales, certain issuances of additional shares to the Interested
Stockholder, transactions with the corporation which increase the proportionate
interest in the corporation directly or indirectly owned by the Interested
Stockholder, or transactions in which the Interested Stockholder receives
certain other benefits.

         The provisions of Section 203, together with the ability of the
Company's board of directors to issue preferred stock without further
stockholder action, could delay or frustrate the removal of incumbent directors
or a change in the Company's control. The provisions also could discourage,
impede or prevent a merger, tender offer or


                                       67

<PAGE>

proxy contest, even if such event would be favorable to the interests of
stockholders. The Company's stockholders, by adopting an amendment to the
Company's Certificate of Incorporation or Bylaws, may elect not to be
governed by Section 203 effective 12 months after such adoption. Neither the
Company's Certificate of Incorporation nor Bylaws currently exclude the
Company from the restrictions imposed by Section 203.

                              SUBSCRIPTION AND SALE

         Pursuant to the terms of the Agency Agreement, the Company will pay the
Agent an advisory fee of $200,000 payable in Common Stock and will reimburse the
Agent for all reasonable out-of-pocket expenses, including legal expenses. In
addition, the Company will pay the Agent a fee payable in cash equal to 8% of
the gross cash proceeds resulting from the sale of the Preferred Stock offered
by the Company pursuant to the terms of this Offering and a fee payable in
Common Stock equal to 4% of the nominal value of the Notes tendered in exchange
for the Preferred Stock. Common Stock issued with respect to the 4% fee shall be
offset against the shares issued to the Agent with respect to the $200,000 fee
referenced above. The Company shall also pay the Agent a fee payable in Common
Stock of $100,000 for advice on structuring and documentation and for ongoing
financial services. All Common Stock issued with respect to the fees referenced
in this paragraph will be valued at a per share price of Cdn. $0.35. The Company
will indemnify the Agent against certain liabilities in connection with the
offer and sale of the Preferred Stock. Pursuant to the terms of the Agency
Agreement, the Company will issue to the Agent phantom common share purchase
warrants with each warrant representing the right to receive a cash payment from
the Company equal to the difference (i) between the closing Market Price of the
Common Stock on the Stock Exchange Business Day prior to the date of exercise
and (ii) the lower of Cdn.$0.35 or the Preferred Conversion Price as of April 1,
2000. The number of warrants issued shall be equal to the quotient of (a) the
sum of 10% of the aggregate cash proceeds of the Offering plus 1% of the nominal
value of Notes exchanged for Preferred Stock divided by (b) Cdn. $0.35. The
warrants will have a term of two years. In addition to the foregoing, in
exchange for the Agent agreeing to provide services as a European conversion
agent, the Company shall pay the Agent an annual fee of $15,000 with the first
payment due on the Closing Date and subsequent payments due on each anniversary
thereof that Preferred Stock remains outstanding.

                              TAX CONSIDERATIONS

UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

         GENERAL

         The following are the material United States federal income tax
consequences of an exchange (the "Exchange") of Preferred Stock for Notes
pursuant to the Offering to the Company and to U.S. Holders and Non-U.S. Holders
(as such terms are defined below) and the material United States federal income
and estate tax consequences to Non-U.S. Holders of holding and disposing of the
Notes or Preferred Stock. This discussion is based on the United States Internal
Revenue Code of 1986, as amended (the "Code"), existing and proposed Treasury
Regulations ("Regulations") promulgated thereunder, Internal Revenue Services
("IRS") rules and pronouncements, reports of congressional committees, judicial
decisions and current administrative rulings and practice, all as in effect on
the date hereof. This discussion is based on current law, which is subject to
change. Any such change could be retroactive and, accordingly, could modify the
tax consequences discussed herein. No advance ruling from the IRS with respect
to the matters discussed herein has been requested. THIS DISCUSSION OF UNITED
STATES FEDERAL INCOME TAX CONSEQUENCES REPRESENTS COUNSEL'S BEST LEGAL JUDGEMENT
AND IS NOT BINDING ON THE IRS OR ANY COURT AND NO ASSURANCE CAN BE GIVEN THAT
THE IRS WILL NOT CHALLENGE PART OR ALL OF THE CONCLUSIONS REACHED HEREIN OR THAT
A CHALLENGE WOULD NOT BE SUCCESSFUL. FURTHERMORE, THIS DISCUSSION RELIES UPON
AND IS PREMISED UPON THE ACCURACY OF STATEMENTS AND REPRESENTATIONS OF THE
COMPANY.

         This discussion does not address tax considerations applicable to U.S.
Holders (as defined below) who actually or constructively own 10% or more (by
vote or value) of the stock of the Company. Furthermore, this discussion does
not address all of the United States federal income tax consequences that may be
relevant to particular shareholders in light of their personal circumstances or
to certain types of shareholders (such as dealers in securities, insurance
companies, foreign individuals and entities, financial institutions and
tax-exempt entities) who may be subject to special treatment under the federal
income tax laws. This discussion also does not address the federal income tax
consequences to holders of stock options or to shareholders who acquired their
stock of the Company through the exercise of employee stock options or otherwise
as compensation. Furthermore, this discussion does not address any tax
consequences under state, local or foreign law.

         For purposes of this discussion, the term "U.S. Holder" means a
beneficial owner of the stock or notes of the Company that is for United States
federal income tax purposes (i) a citizen or resident of the United States; (ii)
a corporation or partnership created or organized in the United States or under
the laws of the United States or of any State thereof; or (iii) an estate or
trust described in Section 7701(a)(3) of the Code. The term "Non-U.S. Holder"
means a beneficial owner of the stock or notes of the Company that is not a U.S.
Holder. Furthermore, the following discussion of the United States federal
income tax consequences is limited to (a) U.S. Holders and Non-U.S. Holders who
hold notes and/or shares of stock and/or will hold notes and/or shares of stock
as "capital assets" within the meaning of Section 1221 of the Code; (b) U.S.
Holders whose ownership, receipt or disposition of stock and/or notes is not
attributable to a permanent establishment in a country other than the United
States for purposes of an income tax treaty to which the United States is a
party; (c) Non-U.S. Holders whose ownership, receipt or disposition of stock
and/or notes is not attributable either to the conduct of a trade or business in
the United States or to a permanent establishment in the United States;
(d) Non-U.S. Holders who do not actually or constructively own (and have not
at any time in the preceding five-year period actually or constructively
owned) five percent or more (by vote or value) of the stock of the Company;
(e) U.S. Holders who are not residents of a country other than the United
States for purposes of an income tax treaty to which the United States is a
party; and (f) Non-U.S. Holders who are not residents of the United States
for purposes of United States federal income tax law or an income tax treaty
to which the United States is a party. U.S. Holders and Non-U.S. Holders who
do not meet one or more of the foregoing criteria are urged to consult their
tax advisors regarding their particular United States federal income tax
consequences.


                                       74

<PAGE>

THE FOLLOWING DISCUSSION IS FOR GENERAL INFORMATION AND IS NOT TAX ADVICE.
ACCORDINGLY, EACH HOLDER OF STOCK, INCLUDING PREFERRED STOCK, OR NOTES IS
ADVISED TO CONSULT HIS TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES OF THE
EXCHANGE AND OF HOLDING AND DISPOSING OF NOTES OR STOCK OF THE COMPANY INCLUDING
THE APPLICATION AND EFFECT OF STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX LAWS
AND ANY PENDING OR PROPOSED LEGISLATION.


UNITED STATES INCOME TAX CONSEQUENCES OF THE EXCHANGE

         EXCHANGE OF THE NOTES FOR PREFERRED STOCK - COMPANY

         The transfer of Preferred Stock to the holders of Notes in the Exchange
should constitute a reorganization within the meaning of Section 368(a)(1)(E) of
the Code. The Exchange will give rise to discharge of indebtedness income to the
Company to the extent the issue price of the Notes exceeds the fair market value
of the Preferred Stock. Based on the Company's representations that the issue
price of the Notes will not exceed the fair market value of the Preferred Stock,
the Company should not recognize income from discharge of indebtedness, or
otherwise, in the Exchange.

         EXCHANGE OF THE NOTES FOR PREFERRED STOCK - U.S. HOLDERS

         Based on the foregoing conclusion that the Exchange will qualify as a
reorganization, a U.S. Holder should not recognize gain or loss upon the
exchange of Notes or Notes and cash for Preferred Stock. The U.S. Holder's tax
basis in shares of Preferred Stock received in the exchange should be the same
as the U.S. Holder's tax basis of the Notes exchanged therefor (increased by the
amount of any cash exchanged and reduced by the portion of such tax basis
allocable to any fractional Preferred Stock interest for which the U.S. Holder
receives a cash payment from the Company). In addition, the holding period of
the Preferred Stock received in the Exchange should include the holding period
of the Notes exchanged therefor (to the extent that Notes, and not cash, were
exchanged). A U.S. Holder generally should recognize gain (or loss) upon the
Exchange to the extent that any cash paid in lieu of a fractional share of
Preferred Stock exceeds (or is less than) such holder's tax basis allocable to
such fractional share. In addition, because the Exchange is not substantially
the same as the receipt of a stock dividend, the Preferred Stock should not be
"section 306 stock."

UNITED STATES FEDERAL INCOME TAX CONSEQUENCES TO U.S. HOLDERS OF OWNING AND
DISPOSING OF PREFERRED STOCK OR NOTES

         CASH DIVIDENDS PAID ON PREFERRED STOCK

         Cash dividends paid on the Preferred Stock will be taxable to a U.S.
Holder as ordinary income, to the extent paid out of the Company's current or
accumulated earnings and profits. Subject to certain restrictions, dividends
received by a corporate U.S. Holder generally should be eligible for the seventy
percent (70%) dividends-received deduction.

         IN-KIND DIVIDENDS PAID ON PREFERRED STOCK

         In-kind dividends paid on the Preferred Stock in Common Stock will be
taxable to a U.S. Holder as ordinary income. The U.S. Holder's basis in the
Common Stock received will be the value of the shares distributed and the
holding period for such shares will commence on the day ownership of the Common
Stock is acquired by the U.S. Holder. Subject to certain restrictions, dividends
received by a corporate U.S. Holder generally should be eligible for the seventy
percent (70%) dividends-received deduction.

         SALE OF PREFERRED STOCK

         In general, a U.S. Holder of Preferred Stock who sells or otherwise
disposes of such stock in a taxable transaction will recognize long-term capital
gain or loss on the difference between the cash and the fair market value of any
property received from that sale and the U.S. Holder's tax basis in such
Preferred Stock deemed held for more than twelve (12) months as of the date of
sale or disposition.


                                       75

<PAGE>

         CONVERSION OF PREFERRED STOCK TO COMMON STOCK

         A U.S. Holder should not recognize gain or loss upon the conversion of
Preferred Stock for Common Stock. The U.S. Holder's tax basis in shares of
Common Stock received in any such conversion should be the same as the U.S.
Holder's tax basis of the Preferred Stock exchanged therefor (reduced by the
portion of such tax basis allocable to any fractional Common Stock interest for
which the U.S. Holder receives a cash payment from the Company). In addition,
the holding period of the Common Stock received in the exchange should include
the holding period of the Preferred Stock that was exchanged therefor. A U.S.
Holder generally should recognize gain (or loss) upon the exchange to the extent
that any cash paid in lieu of a fractional share of Common Stock exceeds (or is
less than) its tax basis allocable to such fractional share.

         ADJUSTMENTS TO CONVERSION PRICE

         Pursuant to Treasury Regulations promulgated under Section 305 of the
Code, a U.S. Holder of Preferred Stock should be treated as having received a
constructive distribution from the Company upon an adjustment in the conversion
price of the Preferred Stock if (i) as a result of such adjustment, the
proportionate interest of such U.S. Holder in the assets or earnings and profits
of the Company is increased and (ii) the adjustment is not made pursuant to a
bona fide, reasonable antidilution formula. An adjustment in the conversion
price would not be considered made pursuant to such formula if the adjustment
were made to compensate for certain taxable distributions with respect to the
Common Stock into which the Preferred Stock is convertible. Thus, under certain
circumstances, a decrease in the conversion price of the Preferred Stock may be
taxable to a U.S. Holder of Preferred Stock as a dividend to the extent of the
current or accumulated earnings and profits of the Company. In addition, the
failure to adjust fully the conversion price of the Preferred Stock to reflect
distributions of stock dividends with respect to the Common Stock may result in
a taxable dividend to the U.S. Holders of the Common Stock.

         TAXATION OF INTEREST ON NOTES

         In general, interest paid on the Notes will be taxable to a U.S. Holder
as ordinary interest income in accordance with the holder's method of tax
accounting at the time that such interest is accrued or (actually or
constructively) received.

         ORIGINAL ISSUE DISCOUNT ON THE NOTES

         The Notes may be initially issued with original issue discount for
United States federal income tax purposes. The amount of original issue discount
with respect to each Note will be equal to the excess of the "stated redemption
price at maturity" of such Note over its "issue price." For these purposes, the
"issue price" of a Note is the initial offering price at which the first Note is
sold. The "stated redemption price at maturity" of each Note will include all
cash payments (other than stated interest to the extent that it is
unconditionally payable at least annually at a single fixed rate ("qualified
stated interest")) required to be made thereunder until maturity. The amount of
original issue discount with respect to a debt instrument is considered to be
zero if such discount is less than one-fourth of one percent of its stated
redemption price at maturity (as defined above) multiplied by the number of
complete years from the issue date to the maturity date of the debt instrument
("de minimis" original issue discount).

         TAXATION OF ORIGINAL ISSUE DISCOUNT ON NOTES

         If there is more than de minimis original issue discount, each holder
of a Note will be required to include in gross income (as ordinary interest
income) an amount equal to the sum of the "daily portions" of the original issue
discount on the Notes for each day such holder holds a Note. The daily portions
of original issue discount required to be included in a holder's gross income
will be determined on a constant yield basis by allocating to each day during
the taxable year in which the holder holds the Notes a pro rata portion of the
original issue discount thereon which is attributable to the "accrual period."
Thus, such original issue discount may be included in income prior to the
receipt of any cash.

         The amount of the original issue discount attributable to each accrual
period will be the product of the "adjusted issue price" of the Notes at the
beginning of such accrual period and the "yield to maturity" of the Notes, less
the amount of any qualified stated interest allocable to the accrual period.
Appropriate adjustments will be made in computing the amount of original issue
discount attributable to the initial accrual period. The adjusted issue price of
the Notes at the beginning of the first accrual period is the issue price.
Thereafter the adjusted issue price of


                                       76

<PAGE>

a Note is the issue price of the Note plus the aggregate amount of original
issue discount that accrued in all prior accrual periods, less payments
(other than payments of qualified stated interest) on the Note. The yield to
maturity of a Note will be the discount rate that, when used to compute the
present value (on a semi-annual compounded basis) of all principal and
interest payments to be made under a Note, produces a present value equal to
the issue price of the Note.

         The "accrual periods" of a Note (other than the initial accrual period)
are each of the six-month periods during the term of the Notes that end on March
31 and September 30 of each year.

         BOND PREMIUM ON NOTES

         If a holder acquires a Note at a premium (as defined below), either at
original issuance or subsequently, the holder may elect to amortize such premium
under recently issued Treasury Regulations. If the election is made, the holder
of a Note generally offsets bond premium allocable to an accrual period against
qualified stated interest income allocable to such accrual period.

         Amortizable bond premium in excess of qualified stated interest for an
accrual period is allowed as a bond premium deduction. However, the amount
allowable as a bond premium deduction for any accrual period is limited to the
amount by which the holder's aggregate interest inclusions on the Note for prior
accrual periods exceeds the aggregate bond premium deductions in such prior
accrual periods. Any excess deduction is carried forward as bond premium in
successive accrual periods.

         The amortizable bond premium on a Note will generally be equal to the
amount, if any, by which the sum of all amounts payable on a Note (other than
qualified stated interest) exceeds the holder's initial tax basis in such Note.
Under the Regulations, amortizable bond premium deduction will be treated as
accruing in each accrual period under a constant yield method over the term of
such Note. However, in certain circumstances, such as a call or prepayment of a
Note, the offset or deduction for unamortized bond premium may be accelerated.

         The "accrual periods" of a Note are each of the six-month periods
during the term of the Notes that end on March 31 and September 30 of each year.

         For the above consequences to apply, the holder must make an election
in the manner prescribed in Regulations Section 1.171-4. Such election applies
not only to the Notes, but to all bonds held by the holder during or after the
taxable year to which the election applies, including all bonds thereafter
acquired. The election is binding for all subsequent taxable years may only be
revoked with the consent of the Commissioner of the Internal Revenue Service.

         MARKET DISCOUNT

         The resale of a Note, or Preferred Stock exchanged for Notes with
"market discount," to a U.S. Holder may be affected by the "market discount"
provisions of the Code. For this purpose, the market discount on a Note will
generally be equal to the amount, if any, by which the stated redemption price
at maturity of the Note immediately after its acquisition exceeds the holder's
tax basis in the Note. Subject to a de minimis exception, these provisions
generally require a U.S. Holder of a Note acquired at a market discount to treat
as ordinary income any principal payment on, or any gain recognized on the
disposition of such Note to the extent of the "accrued market discount" on such
Note at the time of disposition. In general, market discount on a Note will be
treated as accruing on a straight-line basis over the term of such Note, or, at
the election of the holder, under a constant yield method. If a Note exchanged
for Preferred Stock has "market discount," such discount will carry over to the
Preferred Stock and be taxed as interest income when the Preferred stock is
disposed of.

         In addition, any U.S. Holder of a Note acquired at a market discount
may be required to defer the deduction of a portion of the interest on any
indebtedness incurred or maintained to purchase or carry the Note until the Note
is disposed of in a taxable transaction. The foregoing rule will not apply if
the holder elects to include accrued market discount in income currently. This
election to include market discount in income currently, once made, applies to
all market discount obligations acquired on or after the first taxable year to
which the election applies and may not be revoked without the consent of the
IRS.


                                       77

<PAGE>

         SALE, EXCHANGE OR REDEMPTION OF NOTES

         In general, a U.S. Holder of a Note will recognize gain or loss upon
the sale, redemption, retirement or other disposition of a Note measured by the
difference between (i) the amount of cash and the fair market value of any
property received (except to the extent attributable to the payment of accrued
interest) and (ii) the holder's tax basis in the Note. A holder's tax basis in a
Note generally will equal the cost of the Note to the holder increased by the
amount of market discount or original issue discount, if any, previously taken
into income by the holder, or decreased by any bond premium offset or deduction
theretofore allowable to the holder with respect to the Note. Subject to the
market discount rules discussed above, the gain or loss on the disposition of
the Notes will be capital gain or loss and will be long-term gain or loss if the
Notes have been held for more than one year at the time of such disposition.

         BACKUP WITHHOLDING AND INFORMATION REPORTING

         A U.S. Holder of a Note or Preferred Stock may be subject to
information reporting and possible backup withholding. If applicable, backup
withholding would apply at a rate of thirty-one percent (31%) with respect to
interest or dividends on, or the proceeds of a sale, exchange, redemption,
retirement, or other disposition of, such Note or Preferred Stock, as the case
may be, unless (i) such U.S. Holder is a corporation or comes within certain
other exempt categories and, when required, demonstrates this fact, or (ii)
provides a taxpayer identification number, certifies as to no loss of exemption
from backup withholding, and otherwise complies with applicable backup
withholding rules.

UNITED STATES FEDERAL TAX CONSEQUENCES TO NON-U.S. HOLDERS OF OWNING AND
DISPOSING OF PREFERRED STOCK OR NOTES

         DIVIDENDS PAID IN CASH OR COMMON STOCK ON PREFERRED STOCK

         In general, dividends paid to a Non-U.S. Holder with respect to
Preferred Stock, including dividends that are paid in Common Stock, will be
subject to United States withholding tax at a rate of 30 percent (or a lower
rate prescribed by an applicable income tax treaty) unless the dividends are
either (i) effectively connected with a trade or business carried on by the
Non-U.S. Holder within the United States, or (ii) if certain income tax treaties
apply, attributable to a permanent establishment in the United States maintained
by the Non-U.S. Holder. Dividends effectively connected with a United States
trade or business or attributable to a United States permanent establishment
generally will not be subject to United States withholding tax if the Non-U.S.
Holder files certain forms with the payor of the dividend, and generally will be
subject to United States federal income tax on a net income basis, in the same
manner as if the Non-U.S. Holder were a resident of the United States. A
Non-U.S. Holder that is a corporation may be subject to an additional branch
profits tax at a rate of 30% (or such lower rate as may be specified by an
applicable income tax treaty). Under the income tax treaty between the United
States and Canada, the withholding tax rate on dividends paid to most
shareholders who are resident in Canada will be 15%. To determine the
applicability of a tax treaty providing for a lower rate of withholding under
the currently effective Regulations (the "Current Regulations"), dividends paid
to an address in a foreign country are presumed to be paid to a resident of that
country absent knowledge to the contrary. Under Regulations issued on October 7,
1997 (the "Final Regulations") generally effective for payments made after
December 31, 1999, a Non-U.S. Holder (including, in certain cases of Non-U.S.
Holders that are fiscally transparent entities, the owner or owners of such
entities) will be required to provide to the payor certain documentation that
such Non-U.S. Holder (or the owner or owners of such fiscally transparent
entities) is a foreign person in order to claim a reduced rate of withholding
pursuant to an applicable income tax treaty. With respect to dividends paid in
Common Stock, the Non-U.S. Holders' tax basis in such shares will be the value
of the shares for purposes of the dividend and the holding period will commence
on the day ownership of the Common Stock is acquired by the holder.

         SALE OF PREFERRED STOCK

         In general, a Non-U.S. Holder will not be subject to United States
federal income tax on any gain realized upon the sale or other disposition of
such holder's shares of Preferred Stock unless (i) such gain either is
effectively connected with a trade or business carried on by the Non-U.S. Holder
within the United States or, if certain income tax treaties apply, is
attributable to a permanent establishment in the United States maintained by the
Non-U.S. Holder (and in either case, the branch profits tax discussed above may
also apply if the Non-U.S. Holder is a corporation); (ii) the Non-U.S. Holder is
an individual who holds shares of Preferred Stock as a capital asset and is


                                       78

<PAGE>

present in the United States for at least 183 days during the taxable year of
the disposition, and certain other tests are met; or (iii) the Company is or has
been a "United States real property holding corporation" for federal income tax
purposes, as such term is defined by Section 897(c) of the Code, and the
Non-U.S. Holder owned directly or pursuant to certain attribution rules at any
time during the five-year period ending on the date of disposition more than 5%
of the Company's Common Stock (assuming that the Common Stock is regularly
traded on an established securities market, within the meaning of Section
897(c)(3) of the Code and Regulations Sections 1.897-1(m) and 1.897-9T(d)).
Because the Company believes it has been, and that the Company will be, a United
States real property holding corporation and because the Preferred Stock is
convertible into Common Stock and may pay dividends in Common Stock, certain
provisions of the Foreign Investment in Real Property Tax Act of 1980 ("FIRPTA")
discussed below may be relevant to Non-U.S. Holders.

         FIRPTA

         Although capital gains of Non-U.S. Holders from the sale of stock are
generally not subject to U.S. income tax, gains from the sale of a United States
real property holding corporation ("USRPHC") are taxable to such persons,
subject to certain exceptions. The Company is almost certainly a USRPHC since
the value of its indirectly held U.S. mineral holdings equals or exceeds 50% of
the value of its assets used in a trade or business and its real property
interests. Buyers of USRPHC securities are obligated to obtain certain
certifications from sellers, or withhold tax from the sales proceeds. However,
gain on the sale of securities of a USRPHC that are regularly traded on an
established securities market are not subject to the FIRPTA tax, unless the
seller has held more than 5% of such class of stock during the five years
preceding the sale. Thus, the FIRPTA rules are a concern only for the larger
Non-U.S. Holders. Non-U.S. Holders should also be aware that by conversion of
Preferred Stock to Common Stock or by receipt of Common Stock paid as a dividend
on Preferred Stock, or the combined effect of conversions and dividends, such
holders may become holders of more than 5% of the Company's Common Stock and
thus become subject to the FIRPTA rules.

         CONVERSION OF PREFERRED STOCK TO COMMON STOCK

         A Non-U.S. Holder should not recognize gain or loss upon the conversion
of the Preferred Stock into Common Stock except with respect to cash received in
lieu of a fractional share. The Non-U.S. Holder's tax basis in Common Stock
should be the same as the Non-U.S. Holder's tax basis of the Preferred Stock
exchanged therefor (reduced by the portion of such tax basis allocable to any
fractional interest for which the Non-U.S. Holder receives a cash payment from
the Company). In addition, the holding period of the Common Stock received in
the exchange should include the holding period of the Preferred Stock was
exchanged therefor. A holder of Notes generally will recognize capital gain or
loss in connection with any cash received in lieu of a fractional share in an
amount equal to the difference between the amount of cash received and the
adjusted basis of such fractional share. Non-U.S. Holders of Common Stock are
subject to the same rules with respect to taxation of dividends and sales as
described above in the case of holders of Preferred Stock.

         ADJUSTMENTS TO CONVERSION PRICE

         Pursuant to Regulations promulgated under Section 305 of the Code, a
Non-U.S. Holder of Preferred Stock should be treated as having received a
constructive distribution from the Company upon an adjustment in the conversion
price of the Preferred Stock if (i) as a result of such adjustment, the
proportionate interest of such Non-U.S. Holder in the assets or earnings and
profits of the Company is increased and (ii) the adjustment is not made pursuant
to a bona fide, reasonable antidilution formula. An adjustment in the conversion
price would not be considered made pursuant to such formula if the adjustment
were made to compensate for certain taxable distributions with respect to the
Common Stock into which the Preferred Stock is convertible. Thus, under certain
circumstances, a decrease in the conversion price of the Preferred Stock may be
taxable to a Non-U.S. Holder of Preferred Stock as a dividend to the extent of
the current or accumulated earnings and profits of the Company. In addition, the
failure to adjust fully the conversion price of the Preferred Stock to reflect
distributions of stock dividends with respect to the Common Stock may result in
a taxable dividend to the Non-U.S. Holders of the Common Stock.

         INTEREST ON NOTES

         Interest that is paid to a Non-U.S. Holder on a Note that is not United
States trade or business income will not be subject to United States tax if the
interest qualifies as "portfolio interest."


                                       79

<PAGE>

         Generally, interest on Notes in bearer form that is paid by the Company
will qualify as portfolio interest if (i) arrangements were made to ensure that
the Notes would be sold (or resold in connection with the original issue of the
Notes) only to persons that are not U.S. persons; (ii) interest on the Notes is
payable only outside the United States and its possessions; and (iii) the face
of the Notes bears a prescribed legend to the effect that any U.S. persons
holding the Notes will be subject to certain United States tax laws.

         The Company has represented that (i) the Notes were sold only to
persons who were not U.S. persons, (ii) interest on the Notes is payable only
outside the United States and its possessions, and (iii) there will be affixed
to the Notes the following statement: "Any United States person who holds this
obligation will be subject to limitations under the United States income tax
laws, including the limitations provided in section 165(j) and 1287(a) of the
Internal Revenue Code." Based on these representations, interest paid on the
Notes issued in bearer form should qualify for the "portfolio interest"
exception. If a Non-U.S. Holder of Notes owns ten percent or more of the total
combined voting power of all classes of the Company entitled to vote, such
Non-U.S. Holder will not qualify for the portfolio interest exception. Ownership
of stock may occur indirectly, by attribution of ownership of shares held by
other persons and Non-U.S. Holders of Notes should consult their tax advisors in
this regard.

         Generally, interest on notes in registered form will qualify as
portfolio interest if (i) the Non-U.S. Holder does not own, actually or
constructively, 10% or more of the total combined voting power of all classes of
stock of the Company entitled to vote within the meaning of section 871(h)(3) of
the Code and the regulations thereunder; (ii) the Non-U.S. Holder is not a
controlled foreign corporation that is related to the Company through actual or
constructive stock ownership; (iii) the Non-U.S. Holder is not a bank which
acquired the notes in consideration for an extension of credit made pursuant to
a loan agreement entered into in the ordinary course of business; and (iv) the
Company, or its paying agent, receives a properly executed certification as set
forth in Section 871(h) and 881(c) of the Code and the regulations thereunder,
signed under penalties of perjury that the beneficial owner is not a "U.S.
person" for United States federal income tax purposes and which provides the
beneficial owner's name and address.

         Payments of interest, including original issue discount, to a Non-U.S.
Holder that do not qualify for the portfolio interest exception discussed above
and which are not effectively connected with a United States trade or business
will be subject to withholding of United States federal income tax at a rate of
30% unless a United States income tax treaty applies to reduce the rate of
withholding. To claim a treaty reduced rate or an exemption from withholding
because the interest is effectively connected with a United States trade or
business, the Non-U.S. Holder must provide a properly executed Form 1001 (or
successor form) or Form 4224 (or successor form), respectively.

         SALE, EXCHANGE OR REDEMPTION OF NOTES

         Any gain realized by a Non-U.S. Holder on the sale, exchange or
redemption of Notes, generally will not be subject to United States federal
income tax provided that (i) such gain is not effectively connected with a
United States trade or business; (ii) the Non-U.S. Holder is not an individual
who is present in the United States for 183 days or more in the taxable year of
the disposition and meets certain other requirements; and (iii) the Non-U.S.
Holder is not subject to tax pursuant to the provisions of United States tax law
applicable to certain United States expatriates.

ESTATE TAX

         Preferred Stock or Common Stock owned (or treated as owned) by an
individual who, at the time of death, is neither a citizen or a domiciliary of
the United States will be includable in his gross estate for United States
federal estate tax purposes and thus may be subject to United States estate tax,
unless an applicable estate tax treaty provides otherwise. Notes held (or
treated as held) by an individual who is a Non-U.S. Holder at the time of his
death (or theretofore transferred subject to certain retained rights or powers)
will not be subject to United States federal estate tax provided that any
interest thereon would be exempt as portfolio interest if such interest were
received by the Non-U.S. Holder at the time of his death. Such individual's
estate may be subject to United States federal estate tax on the property
includable in the estate for United federal estate tax purposes.

INFORMATION REPORTING AND BACKUP WITHHOLDING

         The Company must report annually to the Internal Revenue Service and to
each shareholder the amount of cash proceeds paid as a result of the Exchange
and dividends paid to, and the tax withheld with respect to, each


                                       80

<PAGE>

shareholder. These reporting requirements apply regardless of whether
withholding was reduced or eliminated by an applicable tax treaty. Copies of
these information returns may also be made available under the provisions of
a specific treaty or agreement with the tax authorities in the country in
which a Non-U.S. Holder resides or is established.

         Under the Current Regulations, United States backup withholding tax
(which generally is imposed at the rate of 31% on certain payments to persons
that fail to furnish the information required under the United States
information reporting requirements) and information reporting requirements
(other than those discussed above under "Dividends Paid in Cash or Common Stock
on Preferred Stock") generally will not apply to dividends paid on Preferred
Stock or Common Stock to a Non-U.S. Holder at an address outside the United
States. Backup withholding and information reporting generally will apply,
however, to dividends paid on shares of Preferred Stock or Common Stock to a
Non-U.S. Holder at an address in the United States, if such holder fails to
establish an exemption or to provide certain other information to the payor.

         Under the Current Regulations, the payment of proceeds from the
disposition of Notes or Preferred Stock to or through a United States office of
a broker will be subject to information reporting and backup withholding unless
the beneficial owner, under penalties of perjury, certifies, among other things,
its status as a Non-U.S. Holder or otherwise establishes an exemption. The
payment of proceeds from the disposition of Notes or Preferred Stock to or
through a non-U.S. office of a non-U.S. broker generally will not be subject to
backup withholding and information reporting except as noted below. In the case
of proceeds from a disposition of Notes or Preferred Stock paid to or through a
non-U.S. office of a broker that is (i) a United States person, (ii) a
"controlled foreign corporation" for United States federal income tax purposes,
or (iii) a foreign person 50% or more of whose gross income from certain periods
is effectively connected with a United States trade or business, information
reporting (but not backup withholding) will apply unless the broker has
documentary evidence in its files that the owner is a Non-U.S. Holder or the
broker otherwise establishes an exemption, provided such broker does not have
actual knowledge that the owner is a U.S. Holder.

         Under the Final Regulations, the payment of dividends, interest, or the
payment of proceeds from the disposition of Notes or Preferred Stock to a
Non-U.S. Holder may be subject to information reporting and backup withholding
unless such recipient provides to the payor certain documentation as to its
status as a Non-U.S. Holder or otherwise establishes an exemption.

         Backup withholding is not an additional tax. Any amounts withheld under
the backup withholding rules from a payment to a Non-U.S. Holder will be
refunded or credited against the Non-U.S. Holder's United States federal income
tax liability, if any, provided that the required information is furnished to
the Internal Revenue Service in a timely manner.

phrases occur. The word "or" is not exclusive, and the word "including" (in
its various forms) means "including without limitation". Pronouns in
masculine, feminine and neuter genders shall be construed to include any
other gender, and words in the singular form shall be construed to include
the plural and vice versa, unless the context otherwise requires.

         Section 1.5. CALCULATIONS AND DETERMINATIONS. All calculations under
the Loan Documents of interest chargeable with respect to Loans and of fees
shall be made on the basis of actual days elapsed (including the first day
but excluding the last) and a year of 360 days. Each determination by Lender
of amounts to be paid under Section 3.2 or any other matters which are to be
determined hereunder by Lender (such as any Business Day) shall, in the
absence of manifest error, be conclusive and binding. Unless otherwise
expressly provided herein or unless Lender otherwise consents, all financial
statements and reports

                                       10

furnished to any Lender hereunder shall be prepared and all financial
computations and determinations pursuant hereto shall be made in accordance
with GAAP.

                             ARTICLE II - The Loans

         Section 2.1. COMMITMENT TO LEND; NOTE. Subject to the terms and
conditions hereof, upon Borrower's request from time to time prior December
31, 1997, Lender agrees to make loans to Borrower (collectively, the "LOANS")
as follows: (a) a loan in an amount of up to $8,000,000 to finance the
acquisition of the Oakvale Properties, and (b) one or more additional loans
in an aggregate amount of up to $4,000,000 pursuant to and as set forth in
Schedule 4 attached hereto. The amount of each Loan must be greater than or
equal to $500,000. The obligation of Borrower to repay to Lender the
aggregate amount of all Loans made by Lender, together with interest accruing
in connection therewith, shall be evidenced by a single promissory note (the
"Note") made by Borrower payable to the order of Lender in the form of
Exhibit A with appropriate insertions. The amount of principal owing on the
Note at any given time shall be the aggregate amount of all Loans theretofore
made by Lender minus all payments of principal theretofore received by Lender
on the Note. Interest on the Note shall accrue and be due and payable as
provided herein and therein, with Loans bearing interest at the rate set
forth in the Note (as limited by the provisions of Section 9.8). Borrower may
NOT borrow, repay, and reborrow hereunder.

         Section 2.2. REQUESTS FOR LOANS. Borrower must give to Lender
written notice (or telephonic notice promptly confirmed in writing) of any
requested Loan to be advanced by Lender. Each such notice constitutes a "Loan
Request" hereunder and must:

                  (a)  specify the aggregate amount of any such new Loan and
         the date on which such Loan is to be advanced; and

                  (b)  be received by Lender not later than 10:00 a.m.,
         Houston, Texas time, on the day on which any such Loan is to be
         made.

Each such written request or confirmation must be made in the form and
substance of the "Loan Request" attached hereto as Exhibit B, duly completed.
Each such telephonic request shall be deemed a representation, warranty,
acknowledgment and agreement by Borrower as to the matters which are required
to be set out in such written confirmation. If all conditions precedent to
such Loan have been met, Lender shall promptly make such Loan available to
Borrower.

         Section 2.3. USE OF PROCEEDS. Borrower shall use the first Loan to
finance the acquisition of the Oakvale Properties and any additional Loans to
finance additional acquisition and development-related capital expenditures
pursuant to and as set forth in Schedule 4 attached hereto. In no event shall
the funds from any Loan be used directly or indirectly by any Person for
personal, family, household or agricultural purposes or for the purpose,
whether immediate, incidental or ultimate, of purchasing, acquiring or
carrying any "margin stock" or any "margin securities" (as such terms are
defined respectively in Regulation U and Regulation G promulgated by the
Board of Governors of the Federal Reserve System) or to extend credit to
others directly or indirectly for the purpose of

                                       11
<PAGE>

purchasing or carrying any such margin stock or margin securities. Borrower
represents and warrants that Borrower is not engaged principally, or as one
of Borrower's important activities, in the business of extending credit to
others for the purpose of purchasing or carrying such margin stock or margin
securities.

         Section 2.4. ARRANGEMENT FEE. In consideration of Lender's
commitment to make Loans, Borrower will pay to EnCap Investments, L.C. an
arrangement fee in the amount of $200,000, due and payable on the date hereof.

         Section 2.5. OPTIONAL PREPAYMENTS. Borrower may, upon five Business
Days' notice to Lender, from time to time and without premium or penalty
prepay the Note, in whole or in part, so long as the aggregate amounts of all
partial prepayments of principal on the Note equals $500,000 or any higher
integral multiple of $100,000, and so long as Borrower does not make any
prepayments which would reduce the unpaid principal balance of the Loan to
less than $100,000 without first either (a) terminating this Agreement or (b)
providing assurance satisfactory to Lender in its discretion that Lender's
legal rights under the Loan Documents are in no way affected by such
reduction. Each prepayment of principal under this section shall be
accompanied by all interest then accrued and unpaid on the principal so
prepaid. Any principal or interest prepaid pursuant to this section shall be
in addition to, and not in lieu of, all payments otherwise required to be
paid under the Loan Documents at the time of such prepayment.

                        ARTICLE III - PAYMENTS TO LENDER

         Section 3.1. GENERAL PROCEDURES. Each payment which Borrower owes
under the Loan Documents to Lender must be received by Lender not later than
11:00 a.m., Houston, Texas time on the date such payment becomes due and
payable, in lawful money of the United States of America, without set-off,
deduction or counterclaim, and in immediately available funds. Any payment
received by Lender after such time will be deemed to have been made on the
next following Business Day. Should any such payment become due and payable
on a day other than a Business Day, the maturity of such payment shall be
extended to the next succeeding Business Day, and, in the case of a payment
of principal or past due interest, interest shall accrue and be payable
thereon for the period of such extension as provided in the Loan Document
under which such payment is due. Each payment under a Loan Document shall be
due and payable at the place provided therein and, if no specific place of
payment is provided, shall be due and payable at the place of payment of the
Note. When Lender collects or receives money on account of the Obligations,
Lender shall apply all such money so distributed, as follows:

                  (a)  first, for the payment of all Obligations which are
         then due (and if such money is insufficient to pay all such
         Obligations, first to any reimbursements due Lender under Section
         6.9 or 9.4 and then to the partial payment of all other Obligations
         then due in proportion to the amounts thereof);

                  (b)  then for the prepayment of principal on the Note,
         together with accrued and unpaid interest on the principal so
         prepaid; and

                                      12
<PAGE>

                  (c)  last, for the payment or prepayment of any other
         Obligations.

All payments applied to principal or interest on the Note shall be applied
first to any interest then due and payable, then to principal then due and
payable, and last to any prepayment of principal and interest in compliance
with Section 2.5.

         Section 3.2.  REIMBURSABLE TAXES.  Borrower covenants and agrees
that:

                  (a)  Borrower will indemnify Lender against and reimburse
         Lender for all present and future stamp and other taxes, levies,
         costs and charges whatsoever imposed, assessed, levied or collected
         on or in respect of this Agreement (whether or not legally or
         correctly imposed, assessed, levied or collected), excluding,
         however, any taxes imposed on or measured by the overall net income
         of Lender by any jurisdiction in which Lender is located (all such
         non-excluded taxes, levies, costs and charges being collectively
         called "Reimbursable Taxes" in this section). Such indemnification
         shall be on an after-tax basis, taking into account any taxes
         imposed on the amounts paid as indemnity.

                  (b)  All payments on account of the principal of, and
         interest on, Lender's Loans and Note, and all other amounts payable
         by Borrower to Lender hereunder, shall be made in full without
         set-off or counterclaim and shall be made free and clear of and
         without deductions or withholdings of any nature by reason of any
         Reimbursable Taxes, all of which will be for the account of
         Borrower. In the event of Borrower being compelled by Law to make
         any such deduction or withholding from any payment to Lender,
         Borrower shall pay on the due date of such payment, by way of
         additional interest, such additional amounts as are needed to cause
         the amount receivable by Lender after such deduction or withholding
         to equal the amount which would have been receivable in the absence
         of such deduction or withholding. If Borrower should make any
         deduction or withholding as aforesaid, Borrower shall within 60 days
         thereafter forward to Lender an official receipt or other official
         document evidencing payment of such deduction or withholding.

                  ARTICLE IV - CONDITIONS PRECEDENT TO LENDING

         Section 4.1. DOCUMENTS TO BE DELIVERED. Lender has no obligation to
make its first Loan unless Lender shall have received all of the following,

<PAGE>

         Section 5.1. NO DEFAULT. Neither Borrower nor any Guarantor is in
default in the performance of any of the covenants and agreements contained
in any Loan Document. No event has occurred and is continuing which

Guarantor is duly organized, validly existing and in good standing under the
Laws of its jurisdiction of organization, having all powers required to carry
on its business and enter into and carry out the transactions contemplated
hereby. Each Restricted Person is duly qualified, in good standing, and
authorized to do business in all other jurisdictions within the United States
wherein the character of the properties owned or held by it or the nature of
the business transacted by it makes such qualification necessary, except
where the failure so to qualify will not cause a Material Adverse Change.

         Section 5.3. AUTHORIZATION. Borrower and each Guarantor has duly
taken all action necessary to authorize the execution and delivery by it of
the Loan Documents to which it is a party and to authorize the consummation
of the transactions contemplated thereby and the performance of its

         Section 5.4. NO CONFLICTS OR CONSENTS. The execution and delivery by
Borrower and each Guarantor of the Loan Documents to which each is a party,
the performance by each of its obligations under such Loan Documents, and the
consummation of the transactions contemplated by the various Loan Documents,

organizational documents of any Restricted Person or the Slattery Trust, or
(3) any agreement, judgment, license, order or permit applicable to or
binding upon any Borrower or any Guarantor, (ii) result in the acceleration
of any Indebtedness owed by any Borrower or any Guarantor, or (iii) result in
or require the creation of any Lien upon any assets or properties of Borrower
or any Guarantor except as expressly contemplated in the Loan Documents.
Except as expressly contemplated in the Loan Documents no consent, approval,
authorization or order of, and no notice to or filing with, any Tribunal or
third party is required in connection with the execution, delivery or
performance by Borrower or any Guarantor of any Loan Document or to
consummate any transactions contemplated by the Loan Documents.

general application relating to the enforcement of creditors' rights.

         Section 5.6. INITIAL FINANCIAL STATEMENTS. Borrower has heretofore
delivered to Lender true, correct and complete copies of the Initial
Financial Statements. The Initial Financial Statements fairly present Benz
Energy's and Borrower's Consolidated financial position at the respective
dates thereof and the Consolidated results of Benz Energy's and Borrower's
operations and Benz Energy's and Borrower's Consolidated cash flows for the
respective periods thereof. Since the date of the annual Initial Financial
Statements no

                                      17
<PAGE>

Material Adverse Change has occurred. All Initial Financial Statements were

with respect to Benz Energy's or Borrower's Consolidated financial condition
and not shown in the Initial Financial Statements or disclosed in the
Disclosure Schedule or a Disclosure Report. Except as shown in the Initial
Financial Statements or disclosed in the Disclosure Schedule or a Disclosure
Report, no Restricted Person is subject to or restricted by any franchise,
contract, deed, charter restriction, or other instrument or restriction which
could cause a Material Adverse Change.

         Section 5.8. FULL DISCLOSURE. No certificate, statement or other
information delivered herewith or heretofore by Borrower or any Guarantor to
Lender in connection with the negotiation of this Agreement or in connection
with any transaction contemplated hereby contains any untrue statement of a
material fact or omits to state any material fact known to Borrower or any
Guarantor (other than industry-wide risks normally associated with the types
of businesses conducted by Restricted Persons) necessary to make the
statements contained herein or therein not misleading as of the date made or
deemed made. There is no fact known to Borrower or any Guarantor that has not
been disclosed to Lender in writing which could cause a Material Adverse
Change. There are no statements or conclusions in any Reserve Report which
are based upon or include misleading information or fail to take into account
material information regarding the matters reported therein, it being
understood that each Reserve Report is necessarily based upon professional
opinions, estimates and projections and that none of Borrower, Benz Energy or
Calibre warrants that such opinions, estimates and projections will
ultimately prove to have been accurate. Borrower has heretofore delivered to
Lender true, correct and complete copies of the Initial Reserve Report.

         Section 5.9. LITIGATION. Except as disclosed in the Initial
Financial Statements or in the Disclosure Schedule: (i) there are no actions,

Indebtedness under the Bank One Credit Facility; PROVIDED, any such Liens on the
Oakvale Properties, Old Ocean Properties or any other Oil and Gas Properties
acquired after the date hereof with proceeds of the Loans shall be subordinated,
in form and substance satisfactory to Lender, to the Liens in favor of Lender
under the Security Documents.

         (c) statutory Liens for taxes, statutory mechanics' and materialmen's
Liens incurred in the ordinary course of business, and other similar Liens
incurred in the ordinary course of business, provided such Liens do not secure
Indebtedness and secure only Liabilities which are not delinquent or which are
being contested as provided in Section 6.7.

         (d) as to property which is Collateral, any Liens expressly permitted
to encumber such Collateral under any Security Document covering such
Collateral.

         Section 7.3. LIMITATION ON MERGERS, ISSUANCES OF SECURITIES. Except as
expressly provided in this subsection no Restricted Person will merge or
consolidate with or into any other business entity. Any Subsidiary of Borrower
may, however, be merged into or consolidated with (i) another Subsidiary of
Borrower, so long as a Guarantor is the surviving business entity, or (ii)
Borrower, so long as Borrower is the surviving business entity. Borrower will
not issue any securities other than shares of its common stock and any options
or warrants giving the holders thereof only the right to acquire such shares. No
Subsidiary of Borrower will issue any additional shares of its capital stock or
other securities or any options, warrants or other rights to acquire such
additional shares or other securities except to Borrower and only to the extent
not otherwise forbidden under the terms hereof. No Subsidiary of Borrower which
is a partnership will allow any diminution of Borrower's interest (direct or
indirect) therein.

         Section 7.4. LIMITATION ON SALES OF PROPERTY. No Restricted Person will
sell, transfer, lease, exchange, alienate or dispose of any Collateral or any of

equipment of equal suitability and value.

         (b) inventory (including oil and gas sold as produced and seismic data)
which is sold in the ordinary course of business on ordinary trade terms.

Neither Borrower nor any of Borrower's Subsidiaries will sell, transfer or
otherwise dispose of capital stock of any of Borrower's Subsidiaries except that
any Subsidiary of Borrower may sell or issue its own capital stock to the extent
not otherwise prohibited hereunder. No Restricted Person will discount, sell,
pledge or assign any notes payable to it, accounts receivable or future income
except to the extent expressly permitted under the Loan Documents.

         Section 7.5. LIMITATION ON DIVIDENDS AND REDEMPTIONS. No Restricted
Person will declare or pay any dividends on, or make any other distribution in
respect of, any class of its


                                      28
<PAGE>

capital stock or any partnership or other interest in it, nor will any
Restricted Person directly or indirectly make any capital contribution to or
purchase, redeem, acquire or retire any shares of the capital stock of or
partnership interests in any Restricted Person (whether such interests are now
or hereafter issued, outstanding or created), or cause or permit any reduction
or retirement of the capital stock of any Restricted Person, except as expressly
provided in this section. Such dividends, distributions, contributions,
purchases, redemptions, acquisitions, retirements or reductions may be made by
Borrower and the Guarantors (i) without limitation to Borrower; (ii) to
Guarantors which are Subsidiaries of Borrower, to the extent permitted under the
investment restrictions of Section 7.6. So long as no Default has occurred: (A)
prior to the receipt by Benz Energy of cumulative proceeds of at least
$25,000,000 CND pursuant to one or more equity offerings, Calibre may make
dividends or distributions in an aggregate amount not to exceed $500,000, and
(B) following the receipt by Benz Energy of at least $25,000,000 CND pursuant to
one or more equity offerings, Calibre may make unlimited dividends or
distributions. In addition to the foregoing each Restricted Person may declare
and pay to any Persons dividends payable only in its common stock, so long as
neither Borrower's nor any Guarantor's interest in any of its Subsidiaries is
not thereby reduced.

         Section 7.6. LIMITATION ON INVESTMENTS AND NEW BUSINESSES. No
Restricted Person will (i) make any expenditure or commitment or incur any
obligation or enter into or engage in any transaction except in the ordinary
course of business, (ii) engage directly or indirectly in any business or
conduct any operations except in connection with or incidental to its present
businesses and operations, (iii) make any acquisitions of or capital
contributions to or other investments in any Person, other than Cash
Equivalents, or (iv) make any significant acquisitions or investments in any
properties other than oil and gas properties.

         Section 7.7. LIMITATION ON CREDIT EXTENSIONS. Except for Cash
Equivalents, no Restricted Person will extend credit, make advances or make
loans other than (i) normal and prudent extensions of credit to customers buying
goods and services in the ordinary course of business, including extensions of
credit to Affiliates buying goods and services in the ordinary course of
business and permitted under Section 7.8, which extensions shall not be for
longer periods than those extended by similar businesses operated in a normal
and prudent manner, and (ii) loans to Borrower.

         Section 7.8. TRANSACTIONS WITH AFFILIATES. No Restricted Person will
engage in any material transaction with any of its Affiliates on terms which are
less favorable to it than those which would have been obtainable at the time in
arm's-length dealing with Persons other than such Affiliates.

         Section 7.9. CERTAIN CONTRACTS; AMENDMENTS; MULTIEMPLOYER ERISA PLANS.
Except as expressly provided for in the Loan Documents, no Restricted Person
will, directly or indirectly, enter into, create, or otherwise allow to exist
any contract or other consensual restriction on the ability of any Subsidiary of
Borrower to: (i) pay dividends or make other distributions to Borrower, (ii) to
redeem equity interests held in it by Borrower, (iii) to repay loans and other
indebtedness owing by it to Borrower, or (iv) to transfer any of its assets to
Borrower. No Restricted Person will amend or permit any amendment to any
contract or lease which releases, qualifies, limits, makes contingent or
otherwise detrimentally affects the


                                      29
<PAGE>

rights and benefits of Lender under or acquired pursuant to any Security
Documents. No ERISA Affiliate will incur any obligation to contribute to any
"multiemployer plan" as defined in Section 4001 of ERISA. The Bank One Credit
Facility shall not be amended, extended, renewed or increased without the prior
written consent of Lender.

         Section 7.10. GENERAL AND ADMINISTRATIVE EXPENSES. Consolidated general

Obligations shall thereupon be immediately due and payable, without demand,
presentment, notice of demand or of dishonor and nonpayment, protest, notice of
protest, notice of intention to accelerate, declaration or notice of
acceleration, or any other notice or declaration of any kind, all of which are
hereby expressly waived by Borrower and each Guarantor who at any time ratifies
or approves this Agreement. Upon any such acceleration, any obligation of Lender

which it may have. All rights, remedies and powers conferred upon Lender under
the Loan Documents shall be deemed cumulative and not exclusive of any other
rights, remedies or powers available under the Loan Documents or at Law or in
equity.

         Section 9.1.  WAIVERS AND AMENDMENTS; ACKNOWLEDGEMENTS.

         (a) WAIVERS AND AMENDMENTS. No failure or delay (whether by course of
conduct or otherwise) by Lender in exercising any right, power or remedy which
Lender may have under any of the Loan Documents shall operate as a waiver
thereof or of any other right, power or remedy, nor shall any single or partial
exercise by Lender of any such right, power or remedy preclude any other or
further exercise thereof or of any other right, power or remedy. No waiver of
any provision of any Loan Document and no consent to any departure therefrom
shall ever be effective unless it is in writing and signed as provided below in
this section, and then such waiver or consent shall be effective only in the
specific instances and for the purposes for which given and to the extent
specified in such writing. No notice to or demand on any Restricted Person shall
in any case of itself entitle any Restricted Person to any other or further
notice or demand in similar or other circumstances. This Agreement and the other
Loan Documents set forth the entire understanding between the parties hereto
with respect to the transactions contemplated herein and therein and supersede
all prior discussions and understandings with respect to the subject matter
hereof and thereof, and no waiver, consent, release, modification or amendment
of or supplement to this Agreement or the other Loan Documents shall be valid or
effective against any party hereto unless the same is in writing and signed by
such party.

         (b) ACKNOWLEDGEMENTS AND ADMISSIONS. Borrower hereby represents,
warrants, acknowledges and admits that (i) it has been advised by counsel in the
negotiation, execution and delivery of the Loan Documents to which it is a
party, (ii) it has made an independent decision to enter into this Agreement and

representation, warranty, covenant or undertaking by Lender or Lender, whether
written, oral or implicit, other than as expressly set out in this Agreement or
in another Loan Document delivered on or after the date hereof, (iii) there are
no representations, warranties, covenants, undertakings or agreements by Lender
as to the Loan Documents except as expressly set out in this Agreement or in
another Loan Document delivered on or after the date hereof, (iv) no Lender has
any fiduciary obligation toward Borrower with respect to any Loan Document or
the transactions contemplated thereby, (v) the relationship pursuant to the Loan
Documents between Borrower and the other Restricted Persons, on one hand, and
Lender, on the other hand, is and shall be solely that of debtor and creditor,
respectively, (vi) no partnership or joint venture exists with respect to the
Loan Documents between any Restricted Person and Lender, (vii) should an Event
of Default or Default occur or exist, Lender will determine in its sole
discretion and for its own reasons what remedies and actions it will or will not
exercise or take at that time, (viii) without limiting any of the foregoing,
Borrower is not relying upon any representation or covenant by Lender, or any
representative thereof, and no such representation or covenant has been made,
that Lender will, at the time of an Event of Default or Default, or at any other
time, waive, negotiate, discuss, or take or refrain from taking any action
permitted under the Loan Documents with respect to any such Event of Default or
Default or any other provision of the Loan Documents, and (ix) all Lender have
relied upon the truthfulness of the acknowledgements in this section in deciding
to execute and deliver this Agreement and to become obligated hereunder.

         (c) REPRESENTATION BY LENDER. Lender hereby represents that it will
acquire its Note for its own account in the ordinary course of its commercial
lending business; however, the disposition of Lender's property shall at all
times be and remain within its control and, in particular and without
limitation, Lender may sell or otherwise transfer the Note as provided in
Section 9.5.

         (d) JOINT ACKNOWLEDGMENT. THIS WRITTEN AGREEMENT AND THE OTHER LOAN
DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.

         Section 9.2. SURVIVAL OF AGREEMENTS; CUMULATIVE NATURE. All of
Restricted Persons' various representations, warranties, covenants and
agreements in the Loan Documents shall survive the execution and delivery of
this Agreement and the other Loan Documents and the performance hereof and
thereof, including the making or granting of the Loans and the delivery of the
Notes and the other Loan Documents, and shall further survive until all of the
Obligations are paid in full to Lender and all of Lender' obligations to
Borrower are terminated. All statements and agreements contained in any
certificate or other instrument delivered by any Restricted Person to Lender
under any Loan Document shall be deemed representations and warranties by
Borrower or agreements and covenants of Borrower under this Agreement. The
representations, warranties, indemnities, and covenants made by Restricted
Persons in the Loan Documents, and the rights, powers, and privileges granted to
Lender in the Loan Documents, are cumulative, and, except for expressly
specified waivers and consents, no Loan Document shall be construed in the
context of another to diminish, nullify, or otherwise reduce the benefit to
Lender of any such representation, warranty, indemnity, covenant, right, power
or privilege. In particular and without limitation, no exception set out in this
Agreement to any representation, warranty, indemnity, or covenant herein
contained shall apply to any similar representation, warranty, indemnity, or
covenant contained in any other Loan Document, and each such similar
representation, warranty, indemnity, or covenant shall be subject only to those
exceptions which are expressly made applicable to it by the terms of the various
Loan Documents.

         Section 9.3. NOTICES. All notices, requests, consents, demands and
other communications required or permitted under any Loan Document shall be in

Persons at the address of Borrower specified on the signature pages hereto and

hours at the address provided herein, (b) in the case of telecopy or telex, upon
receipt, or (c) in the case of registered or certified United States mail, three
days after deposit in the mail; provided, however, that no Loan Request shall
become effective until actually received by Lender.

         Section 9.4.  PAYMENT OF EXPENSES; INDEMNITY.

         (a) PAYMENT OF EXPENSES. Whether or not the transactions contemplated
by this Agreement are consummated, Borrower will promptly (and in any event,

transfer, stamp, mortgage, documentary or other similar taxes, assessments or
charges levied by any governmental or revenue authority in respect of this
Agreement or any of the other Loan Documents or any other document referred to
herein or therein, (ii) all reasonable costs and expenses incurred by or on
behalf of Lender (including attorneys' fees, consultants' fees and engineering

borrowings hereunder and other action reasonably required in the course of
administration hereof, (4) monitoring or confirming (or preparation or
negotiation of any document related to) Borrower's compliance with any covenants
or conditions contained in this Agreement or in any Loan Document, and (iii) all
reasonable costs and expenses incurred by or on behalf of Lender (including
attorneys' fees, consultants' fees and accounting fees) in connection with the
defense or enforcement of any of the Loan Documents (including this section) or
the defense of Lender's exercise of its rights thereunder. In addition to the
foregoing, until and all Obligations have been paid in full, Borrower will also
pay or reimburse Lender for all reasonable out-of-pocket costs and expenses of
Lender or its agents or employees in connection with the continuing
administration of the Loans and the related due diligence of Lender, including
travel and miscellaneous expenses and fees and expenses of Lender's outside
counsel, reserve engineers and consultants engaged in connection with the Loan
Documents.

         (b) INDEMNITY. Borrower agrees to indemnify Lender, upon demand, from
and against any and all liabilities, obligations, claims, losses, damages,
penalties, fines, actions, judgments, suits, settlements, costs, expenses or
disbursements (including reasonable fees of attorneys, accountants, experts and
advisors) of any kind or nature whatsoever (in this section collectively called
"liabilities and costs") which to any extent (in whole or in part) may be
imposed on, incurred by, or asserted against Lender growing out of, resulting
from or in any other way associated with any of the Collateral, the Loan
Documents and the transactions and events (including the enforcement or defense
thereof) at any time associated therewith or contemplated therein (including any
violation or noncompliance with any Environmental Laws by any Restricted Person
or any liabilities or duties of any Restricted Person or Lender with respect to
Hazardous Materials found in or released into the environment).


                                      35
<PAGE>

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM
OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY LENDER,

provided only that no Lender shall be entitled under this section to receive
indemnification for that portion, if any, of any liabilities and costs which is
proximately caused by its own individual gross negligence or willful misconduct,
as determined in a final judgment. If any Person (including Borrower or any of
its Affiliates) ever alleges such gross negligence or willful misconduct by
Lender, the indemnification provided for in this section shall nonetheless be
paid upon demand, subject to later adjustment or reimbursement, until such time
as a court of competent jurisdiction enters a final judgment as to the extent
and effect of the alleged gross negligence or willful misconduct. As used in
this section the term "Lender" shall refer not only to the Persons designated as
such in Section 1.1 but also to each director, officer, agent, attorney,
employee, representative and Affiliate of such Persons.

         Section 9.5. JOINT AND SEVERAL LIABILITY; PARTIES IN INTEREST;
ASSIGNMENTS. All Obligations which are incurred by two or more Restricted
Persons shall be their joint and several obligations and liabilities. All
grants, covenants and agreements contained in the Loan Documents shall bind and
inure to the benefit of the parties thereto and their respective successors and
assigns; provided, however, that no Restricted Person may assign or transfer any
of its rights or delegate any of its duties or obligations under any Loan
Document without the prior consent of Lender. Lender may sell or otherwise
transfer the Note, any participation interest or other interest therein, or any
of its other rights and obligations under the Loan Documents without the consent
of Borrower or any Guarantor.

         Section 9.6. CONFIDENTIALITY. Lender agrees that it will take all
reasonable steps to keep confidential any proprietary information given to it by
any Restricted Person, provided, however, that this restriction shall not apply
to information which (i) has at the time in question entered the public domain,
(ii) is required to be disclosed by Law (whether valid or invalid) of any
Tribunal, (iii) is disclosed to Lender's Affiliates, auditors, attorneys, or
agents, (iv) is furnished to any other Lender or to any purchaser or prospective
purchaser of participations or other interests in any Loan or Loan Document, or
(v) is disclosed in the course of enforcing its rights and remedies during the
existence of an Event of Default.

         Section 9.7. GOVERNING LAW; SUBMISSION TO PROCESS. EXCEPT TO THE EXTENT
THAT THE LAW OF ANOTHER JURISDICTION IS EXPRESSLY ELECTED IN A LOAN DOCUMENT,
THE LOAN DOCUMENTS SHALL BE DEEMED CONTRACTS AND INSTRUMENTS MADE UNDER THE LAWS
OF THE STATE OF TEXAS AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH AND
GOVERNED BY THE LAWS OF THE STATE OF TEXAS AND THE LAWS OF THE UNITED STATES OF
AMERICA, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. CHAPTER 15 OF TEXAS

NOTES. BORROWER HEREBY IRREVOCABLY SUBMITS ITSELF AND EACH OTHER RESTRICTED
PERSON TO THE NON-EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS SITTING
IN THE STATE OF TEXAS AND AGREES AND CONSENTS THAT SERVICE OF PROCESS MAY BE
MADE UPON IT OR ANY RESTRICTED PERSON IN ANY LEGAL PROCEEDING RELATING TO THE
LOAN DOCUMENTS OR THE OBLIGATIONS BY ANY MEANS ALLOWED UNDER TEXAS OR FEDERAL
LAW.

         Section 9.8. LIMITATION ON INTEREST. Lender, Restricted Persons and any
other parties to the Loan Documents intend to contract in strict compliance with
applicable usury law from time to time in effect. In furtherance thereof such
Persons stipulate and agree that none of the terms and provisions contained in
the Loan Documents shall ever be construed to create a contract to pay, for the
use, forbearance or detention of money, interest in excess of the maximum amount
of interest permitted to be charged by applicable law from time to time in
effect. Neither any Restricted Person nor any present or future guarantors,
endorsers, or other Persons hereafter becoming liable for payment of any
Obligation shall ever be liable for unearned interest thereon or shall ever be
required to pay interest thereon in excess of the maximum amount that may be
lawfully charged under applicable law from time to time in effect, and the
provisions of this section shall control over all other provisions of the Loan
Documents which may be in conflict or apparent conflict herewith. Lender
expressly disavow any intention to charge or collect excessive unearned interest
or finance charges in the event the maturity of any Obligation is accelerated.
If (a) the maturity of any Obligation is accelerated for any reason, (b) any
Obligation is prepaid and as a result any amounts held to constitute interest
are determined to be in excess of the legal maximum, or (c) Lender or any other
holder of any or all of the Obligations shall otherwise collect moneys which are
determined to constitute interest which would otherwise increase the interest on
any or all of the Obligations to an amount in excess of that permitted to be
charged by applicable law then in effect, then all sums determined to constitute
interest in excess of such legal limit shall, without penalty, be promptly
applied to reduce the then outstanding principal of the related Obligations or,
at Lender's or holder's option, promptly returned to Borrower or the other payor
thereof upon such determination. In determining whether or not the interest paid
or payable, under any specific circumstance, exceeds the maximum amount
permitted under applicable law, Lender and Restricted Persons (and any other
payors thereof) shall to the greatest extent permitted under applicable law, (i)
characterize any non-principal 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 instruments evidencing the
Obligations in accordance with the amounts outstanding from time to time
thereunder and the maximum legal rate of interest from time to time in effect
under applicable law in order to lawfully charge the maximum amount of interest
permitted under applicable law. In the event applicable law provides for an
interest ceiling under Texas Revised Civil Statutes Annotated article 5069-1.04,
that ceiling shall be the indicated rate ceiling and shall be used when
appropriate in determining the Highest Lawful Rate. As used in this section the
term "applicable Law" means the Laws of the State of Texas or the Laws of the
United States of America, whichever Laws allow the greater interest, as such
Laws now exist or may be changed or amended or come into effect in the future.

         Section 9.9. TERMINATION; LIMITED SURVIVAL. In its sole and absolute
discretion Borrower may at any time that no Obligations are owing elect in a
written notice delivered to Lender to terminate this Agreement. Upon receipt by
Lender of such a notice, if no Obligations are then owing this Agreement and all
other Loan Documents shall thereupon be terminated and the parties thereto
released from all prospective obligations thereunder. Notwithstanding the
foregoing or anything herein to the contrary, any waivers or admissions made by
any Restricted Person in any Loan Document, any Obligations under Section 3.2,
and any obligations which any Person may have to indemnify or compensate Lender
shall survive any termination of this Agreement or any other Loan Document. At
the request and expense of Borrower, Lender shall prepare and execute all
necessary instruments to reflect and effect such termination of the Loan
Documents. Lender is hereby authorized to execute all such instruments on behalf
of all Lender, without the joinder of or further action by Lender.

         Section 9.10. SEVERABILITY. If any term or provision of any Loan
Document shall be determined to be illegal or unenforceable all other terms and
provisions of the Loan Documents shall nevertheless remain effective and shall
be enforced to the fullest extent permitted by applicable Law.

         Section 9.11. COUNTERPARTS. This Agreement may be separately executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to constitute one
and the same Agreement.

         Section 9.12. WAIVER OF JURY TRIAL, PUNITIVE DAMAGES, ETC. BORROWER AND
LENDER HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, AND IRREVOCABLY (A) WAIVES,
TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR DIRECTLY OR INDIRECTLY AT ANY
TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH THE LOAN DOCUMENTS OR ANY
TRANSACTION CONTEMPLATED THEREBY OR ASSOCIATED THEREWITH, BEFORE OR AFTER
MATURITY; (B) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT
MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY "SPECIAL DAMAGES", AS
DEFINED BELOW, (C) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR
AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE,
OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO
ENFORCE THE FOREGOING WAIVERS, AND (D) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO
ENTER INTO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS AND THE TRANSACTIONS
CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS CONTAINED IN THIS SECTION. AS USED IN THIS SECTION, "SPECIAL
DAMAGES" INCLUDES ALL SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES
(REGARDLESS OF HOW NAMED), BUT DOES NOT INCLUDE ANY PAYMENTS OR FUNDS WHICH ANY
PARTY HERETO HAS EXPRESSLY PROMISED TO PAY OR DELIVER TO ANY OTHER PARTY HERETO.

                        [BENZ ENERGY, LTD. LETTERHEAD]


                                                               November 10, 1998


Mr. Joe U. Flores
Mobil Exploration & Production U.S. Inc.
12450 Greenspoint Drive
Houston, Texas 77060-1991


RE:  Old Ocean
     Matagorda and Brazoria County, Texas


Dear Mr. Flores:

     Pursuant to our discussion of November 9, 1998, Benz Energy, Ltd.
("Benz") hereby offers the sum of Two Million Dollars ($2,000,000), net of
any other consideration or credit as hereinafter provided, for the
acquisition of all rights, title and interests in and to any mineral
interest, real or beneficial, that Mobil Producing Texas & New Mexico Inc.
("Mobil") owns: (i) below the base of the deepest unitized formation in the
Old Ocean Unit, which is defined in that certain Old Ocean Field Unitization
Agreement dated January 30, 1947 and recorded in Volume 176 at page 55 of the
Deed Records of Matagorda County, Texas. The deepest producing formation is
commonly referred to as the "Larsen Sand," which is identified by electric
log as the interval between 10,320' and 10,690' measured depth, in the J.S.
Abercrombie Co. and Magnolia Petroleum Co. BRLD - #16 (currently referred to
as Old Ocean Unit Well #79), and (ii) in that certain unrecorded Agreement,
by and between Mobil Producing Texas & New Mexico Inc., Amoco Production
Company and Cheyenne Petroleum Company and dated by amendment effective
October 15, 1997, governing operations for a geophysical 3D survey and
exploration for oil and gas. For purposes of this offer it is the
understanding of Benz that Mobil's undivided working interest is not less than
39.325 Armstrong Zone 36% of 8/8ths interest in the leasehold estate covering
the Old Ocean Unit. Any representation of offer by Benz is contingent upon
Mobil selling all of its rights, title and interests in (i) and (ii) above to
Benz.

     As additional consideration Benz will provide Mobil with a seismic
license to the 3D survey currently being acquired covering lands defined as
the Old Ocean Unit and provide adequate "tails" to ensure a sufficient amount
of coverage for interpretation of the shallow rights reserved by Mobil. Said
license will be transferable one (1) time to any party who acquires all of
the rights, title

<PAGE>

and interests of Mobil from the surface of the earth to the base of the
Larsen Sand in the Old Ocean Unit and will cover only those lands defined as
the Old Ocean Unit.

     Any conveyance of interest by Mobil would be subject to the following:

     1.  Mobil will retain an overriding royalty interest on any mineral
interest covering the Old Ocean Unit equal to the difference between twenty
percent (20%) and burdens, but in no event greater than three percent (3%) of
8/8ths.

     2.  Mobil will retain overriding royalty interest on any oil, gas and
mineral leases acquired by Benz covering lands outside the Old Ocean Unit but
within the AMI boundary of the Agreement, which Mobil is selling to Benz of
two percent (2%) of 8/8ths. By previous letter dated July 17, 1998 Mobil
elected to participate for its proportionate share in certain Geophysical
Option Agreements acquired by Benz within the AMI pursuant to the above
referenced Agreement. Pursuant to the terms and conditions of this letter
proposal, Benz shall credit Mobil for its proportionate share of the option
election in the amount of $565,035.53.

     3.  Sale of Mobil's mineral interest in the Old Ocean Unit below the
base of the Larsen Sand will be conveyed by means of a Term Assignment and
Sublease. The "Term Assignment and Sublease" will be for a period of ten (10)
years from the effective date of such assignment. Upon termination of the ten
(10) year term all lands within the Old Ocean Unit previously assigned and
subleased by Mobil to Benz not allocated to a Development Area, not to exceed
2,000 acres in size, unless otherwise mutually agreed to by Mobil and Benz
shall automatically revert to Mobil. For definition purposes, a "Development
Area" shall be defined as any number of acres reasonably attributable and
supporting development of a particular well which is completed as a producer
in paying quantities from depths below the Larsen Sand.

     4.  Upon execution of this letter and when contractually permitted,
Mobil will provide Benz access to, and copies of, all geological and
subsurface (well and reservoir) information in its possession covering the
Old Ocean Unit. Benz will have the right to disclose such information to
third parties without restriction.

     This offer will expire at the close of business Tuesday, November 10,
1998 in the event Mobil fails to accept this offer as hereinafter provided.


                                      -2-

<PAGE>

     Upon acceptance as herein provided the parties shall immediately begin
negotiating in good faith to formalize a "Purchase and Sale Agreement" which
will be executed within ten (10) business days. The Term Assignment and
Sublease will be executed simultaneously with closing which will occur on or
before December 15, 1998.

Should you have any questions or comments, please advise.


Very truly yours,

         /s/ R. Hiram Lucius

         WRITTEN OPINION OF COUNSEL, WHICH OPINION AND COUNSEL ARE SATISFACTORY
         TO THE CORPORATION, TO THE EFFECT THAT SUCH REGISTRATION IS NOT

Defects which Buyer determines it is unwilling to waive, Buyer shall notify
Seller in writing of such Defects (in this SECTION 7.1, a "DEFECT NOTICE") as
soon as they are identified by Buyer, but in no event later than April 1, 1998
(the "POST-CLOSING EXAMINATION POINT"). Such Defects of which Buyer so provides
notice are herein called "ASSERTED DEFECTS." All Defects, other than an
Indemnified Item, with respect to which Buyer fails to so give Seller notice
will be deemed waived for all purposes. Each Defect Notice shall specify in
reasonable detail the matter which, in Buyer's opinion, constitutes a Defect.


                                    -19-
<PAGE>

         (b) The term "DEFECT" as used in this Section shall mean the following:

                  (i) Seller's ownership of the Properties on or prior to the
         Closing Date is such that, with respect to a well listed on EXHIBIT
         7.1(b)(i) hereto, it (A) entitles Seller to receive a percentage share
         of the oil, gas and other hydrocarbons produced from, or allocated to,
         such well which is less than the percentage share set forth on EXHIBIT
         7.1(b)(i) in connection with such well in the column headed "NRI" or
         (B) causes Seller to be obligated to bear a percentage share of the
         cost of operation of such well greater than the percentage share set
         forth on EXHIBIT 7.1(b)(i) in connection with such well in the column
         headed "WI" (unless the share of production from such well to which
         Seller is entitled is proportionately larger than the "NRI" shown for
         such well on EXHIBIT 7.1(b)(i)); or

                  (ii) Seller's ownership of an Oil and Gas Property on or prior
         to the Closing Date is subject to a lien other than a Permitted
         Encumbrance.

                  (iii) Seller's ownership of an Oil and Gas Property on or
         prior to the Closing Date is subject to a preferential right to
         purchase such property or a requirement that consent to assignment of
         such property be obtained, unless a waiver of such right has been
         obtained with respect to the transaction contemplated hereby or, in the
         case of a preferential right to purchase, an appropriate tender of the
         applicable interest has been made to the party holding such right and
         the period of time required for such party to exercise such right has
         expired without such party exercising such right; or

                  (iv) Seller's ownership of an Oil and Gas Property on or prior
         to the Closing Date is subject to an imperfection in title which, if
         asserted, would cause a Defect, as defined in CLAUSE (i) above, to
         exist, and such imperfection in title is not such as would normally be
         waived by Persons engaged in the oil and gas business who are
         purchasing producing properties; or

                  (v) With respect to any well listed on EXHIBIT 7.1(b)(v),
         Seller and its predecessors in title to the Properties have as of the
         Closing Date collectively taken more gas from such well than the
         ownership of the Properties would entitle it them to receive (an
         "overproduced position").

                   (vi) With respect to the Properties as of the Closing Date:
          (A) Seller is in violation of, and there exists a current unsatisfied
          obligation to perform any cleanup, removal, containment or other
          remediation pursuant to, Environmental Laws; (B) there are proceedings
          pending relating (whether on-site or off-site) to any of the
          Properties under any Environmental Law by any federal, state,
          provincial or local environmental agency or third party; (C) there are
          written demands, notices or claims pending or threatened relating to
          any of the Properties under any Environmental Law, including any
          written notices, demand letters or site-specific requests for
          information from any federal, state, provincial, or local
          environmental agency relating to any liabilities under or


                                    -20-
<PAGE>

          violations of Environmental Laws; or (D) Seller is in breach of its
          representation and warranty set forth in SECTION 4.9(b).

         (c) Buyer waives and releases all claims against Seller, its partners
and its and such partners' parent or subsidiary companies or other affiliates,
and its and their respective shareholders, members, owners, directors, officers,
managers, employees and agents, for injury to, or death of, Persons or for
damage to property arising in any way from the conduct of the investigations and
examinations contemplated by this Section (or the exercise of Buyer's rights of
access under ARTICLE VI) or the conduct of its employees, agents or contractors
in connection with such investigations and examinations (or the exercise of such
rights of access). Buyer shall indemnify Seller, its partners and its and such
partners' parent and subsidiary companies and other affiliates, and its and
their respective shareholders, members, owners, directors, officers, managers,
employees and agents from and against any and all claims, actions, liabilities,
losses, damages, costs or expenses (including court costs and attorney fees)
whatsoever arising out of the exercise of such rights of investigation and
examination (or exercise of such rights of access).

         SECTION 7.2.  CERTAIN PRICE ADJUSTMENTS.

         (a) In the event that, as a part of the due diligence review provided
for in SECTION 7.1 above, Asserted Defects are presented to Seller and Seller is
unable (or unwilling) to cure such Asserted Defects to the reasonable
satisfaction of Buyer prior to September 1, 1998, then Buyer and Seller shall,
with respect to each Oil and Gas Property affected by one or more Defects,
attempt to agree upon an appropriate adjustment to the Base Purchase Price to
account for such Defects. Notwithstanding anything herein to the contrary, Buyer
and Seller shall elect to specify as an appropriate adjustment to the Base
Purchase Price (A) for a Defect of the type which is specified in SECTION
7.1(b)(i) or SECTION 7.1(b)(iv), and which relates to the NRI specified on
EXHIBIT 7.1(b)(i), an amount equal to X multiplied by Y, where "X" is the amount
specified on EXHIBIT 7.1(b)(i) for the Oil and Gas Property to which such Defect
relates, and where "Y" is the proportionate reduction in NRI (e.g., the amount
by which the share of production to which Seller is actually entitled is less
than the NRI specified for such Oil and Gas Property on EXHIBIT 7.1(b)(i),
divided by such NRI specified on EXHIBIT 7.1(b)(i)), (B) for a Defect of the
type specified in SECTION 7.1(b)(ii), the amount required to discharge such
lien, or (C) for a Defect of the type specified in SECTION 7.1(b)(v), the amount
represented by the loss of volumes required to discharge such overproduced
position, which amounts shall be the discounted present value of the volumes
required to discharge such obligation, determined by using a 10% discount rate
and assuming the same would be discharged as promptly as possible (under the
terms of applicable agreements) after the Closing Date assuming production
occurs at the same rate as projected in projections of production furnished by
Buyer as (and represented by Buyer to be) its projections used in making its
decision to purchase (and valuing such production using prices for production
utilized in such projections).

         (b) Should Seller determine (or should Buyer, in the course of its due
diligence review contemplated by SECTION 7.1, determine) that (i) the ownership
of the Properties by Seller entitles

                                     -21-
<PAGE>

Seller to a share of the production from a well listed on EXHIBIT 7.1(b)(i)
greater than the share shown for such well under the column headed "NRI" on
EXHIBIT 7.1(b)(i), or (ii) with respect to any well listed in EXHIBIT 7.1(b)(v)
Seller and its predecessors in title have taken less gas than their ownership in
such Oil and Gas Property would entitle them to take, or is in an overproduced
position less than that shown on EXHIBIT 7.1(b)(v), then Seller may propose an
upward adjustment to the Base Purchase Price to account for such fact, in which
case such adjustment shall be handled in the same manner as provided above with
respect to adjustments for Asserted Defects.

         (c) Any reduction to the Base Purchase Price under this SECTION 7.2
(in this SUBSECTION (c) called the "REDUCTION AMOUNT") shall be effected in
the following manner:

                  (i) If the Note is still outstanding at the time of the
         reduction, the outstanding principal amount of the Note shall be
         reduced on a dollar-for-dollar basis in an amount equal to the
         Reduction Amount (provided, that in connection therewith (A) first,
         the Preferred Portion of the Purchase Price shall be deemed reduced
         on a dollar-for-dollar basis; and (B) second, to the extent the
         Reduction Amount has not been fully offset pursuant to the
         immediately preceding CLAUSE (a), the Common Portion of the Purchase
         Price shall be deemed reduced on a dollar-for-dollar basis).

                  (ii) If the Note has been converted at the time of the
         reduction, the number of Seller's Common Shares and Preferred Shares
         received hereunder shall be reduced as follows: (A) first, the number
         of Preferred Shares shall be reduced on a share-for-share basis in an
         amount derived by dividing the Remaining Amount by $1.00; and (B)
         second, to the extent the Reduction Amount has not been fully offset
         pursuant to the immediately preceding CLAUSE (a) (the amount of the
         Reduction Amount not offset being called the "REMAINING AMOUNT") the
         number of Common Shares shall be reduced on a share-for-share basis by
         the number of shares equal to the lesser of (1) the number of shares
         derived by dividing the Remaining Amount by the Average Closing Price
         and (2) the number of Common Shares into which the Note was converted
         hereunder.

         (d) Notwithstanding SUBSECTION (c) above, Seller shall have the right
to transfer and assign to Buyer additional oil and gas properties located in the
same general area as the Oil and Gas Properties (in this Section, "SUBSTITUTE
PROPERTIES"), which transfer and assignment would be in lieu of, or in
conjunction with, an adjustment to the Base Purchase Price under this Section.
If substitute properties are transferred and assigned to Buyer under this
SUBSECTION (d), the Reduction Amount shall be offset by the PV-10 Value (as
defined below) of the substitute properties. Any transfer and assignment by
Seller under this SUBSECTION (d) shall, however, be subject to the Buyer having
(A) concurred in good faith with the PV-10 Value of the substitute properties
and (B) made a good faith determination that (1) Buyer will receive good and
defensible title to the substitute properties, (2) there are no material
environmental or similar liabilities associated with the substitute properties
and (3) there are no other matters or items that a reasonable and prudent
purchaser of oil and gas properties would consider as materially adversely
affecting the value of, or proposed operations on, the substitute properties;
such transfer and

                                     -22-
<PAGE>

assignment by Seller shall also be further subject to receipt by Buyer of the
concurrence of its lender under the Senior Credit Facility as to the PV-10
Value of the substitute properties and lender's approval of the substitute
properties as acceptable additional collateral for the Senior Credit
Facility. As used in this SUBSECTION (d), the term "PV-10 VALUE" shall mean,
when used with respect to any substitute properties, the pre-income tax value
of projected net revenues (utilizing a 10% discount factor) from Proved
Reserves (as defined in the definition for Oil and Gas Reserves promulgated
by the Society of Petroleum Engineers, or any generally recognized successor)
attributable to such substitute properties as set forth in an Approved
Reserve Report. As used in this SUBSECTION (d), the term "APPROVED RESERVE
REPORT" shall mean a reserve report prepared in accordance with customary and
generally accepted standards and practices for petroleum engineers, and shall
be based on prices, costs and other assumptions as shall be designated by
Seller and approved by Buyer (which approval shall not be unreasonably
withheld. The petroleum engineer or engineers that prepare an Approved
Reserve Report shall be designated by Seller and approved by Buyer (which
approval shall not be unreasonably withheld).

         SECTION 7.3. WAIVER. Without limiting SECTION 7.1 and
notwithstanding anything else herein to the contrary, all Defects (except for
a Defect which is an Indemnified Item) not raised or asserted by Buyer within
the requisite time periods specified in SECTION 7.1 shall be waived by Buyer
for all purposes, and Buyer shall have no right to seek an adjustment to the
Purchase Price, make a claim against Seller or seek indemnification from
Seller with respect thereto (except as otherwise provided (a) in ARTICLE XI,
with respect to claims arising under Environmental Laws, and (b) ARTICLE XII,
with respect to an Indemnified Item). It is not the intent of this SECTION
7.3, however, to waive Buyer's right to enforce the other terms and
conditions of this Agreement with respect to matters other than Defects,
including Seller's representations, warranties, covenants, agreements and
indemnifications insofar as they relate to matters other than Defects.

                                  ARTICLE VIII

         CONDITIONS PRECEDENT TO THE OBLIGATIONS OF THE PARTIES; TERMINATION

not met as of the Closing Date, or in the event the Closing does not occur on
or before the Closing Date, and (in either case) Buyer is not in breach of
its obligations hereunder in the absence of Seller also being in breach of its
obligations hereunder, this Agreement may, at the option of Buyer, be
terminated, in which case the parties shall have no further obligations to
one another hereunder (other than the obligations under SECTIONS 6.1 and
7.1(c) and ARTICLE XVII which will survive such termination).

         SECTION 8.2. CONDITIONS PRECEDENT TO THE OBLIGATIONS OF SELLER. The

connection with the consummation of the transactions contemplated by this
Agreement.

         (d) Seller shall have received an opinion of counsel or counsels
reasonably acceptable to Seller dated the Closing Date covering the matters
described in EXHIBIT 8.2(d) and in a form reasonably acceptable to Seller.

         (e) The letter of intent dated as of November 17, 1997, by and among
Buyer, Calibre Energy, L.L.C., Slattery Trust, Starbucks Trust, Todd Grabois,
Robert Novak and Prentis B. Tomlinson, Jr., shall be in full force and

<PAGE>

either case) Seller is not in breach of its obligations hereunder in the
absence of Buyer also being in breach of its obligations hereunder, this
Agreement may, at the option of Seller, be terminated, in which case the
parties shall have no further obligations to one another hereunder (other
than the obligations under SECTIONS 6.1 and 7.1(c) and ARTICLE XVII which
will survive such termination).


                                 ARTICLE IX

                             CLOSING OF TRANSACTION


         SECTION 9.1. THE CLOSING. The closing (herein called the "CLOSING")
of the transaction contemplated hereby shall take place in the offices of
Thompson & Knight, P.C., at 1700 Texas Commerce Tower, 600 Travis Street,

                  (a) execute, acknowledge and deliver to Buyer Assignments
         of the Properties (the "ASSIGNMENTS"), in the form attached hereto
         as EXHIBIT 9.2(a), being effective as to runs of oil and deliveries
         of gas as of 12:01 o'clock a.m., Central Daylight Time on December

                  (c) to the extent requested by Buyer, execute and deliver
         an affidavit or other certification (as permitted by such code) that
         Seller is not a "foreign Person" within the meaning of Section 1445
         (or similar provisions) of the Internal Revenue Code of 1986 as
         amended (I.E., Seller is not a non-resident alien, foreign
         corporation, foreign partnership, foreign trust or foreign estate as

         Agreement substantially in the form of the document attached hereto
         as EXHIBIT 9.2(d).

         SECTION 9.3. BUYER'S CLOSING OBLIGATIONS. At the Closing, Buyer shall:

                  (a) deliver to the Seller, a convertible promissory note
         substantially in the form attached hereto as EXHIBIT 9.3(a) in the
         principal amount equal to the Base Purchase Price, as adjusted in
         ARTICLE X (the "NOTE");

                                     -25-
<PAGE>

                  (b) (i) furnish to Seller such evidence (including, without
         limitation, evidence of satisfaction of all applicable bonding
         requirements) as Seller may require that Buyer is qualified with the
         applicable authorities to succeed Seller as the owner and, where

         SECTION 9.4. DELIVERY OF FILES. Within 30 days after the Closing,
Seller shall deliver to Buyer the files and other materials referenced in
SUBSECTION (e) of ARTICLE II. Notwithstanding the foregoing, to the extent
such files or other materials include items which Seller cannot provide to
Buyer without, in the opinion of Seller, breaching confidentiality agreements
with other parties, Seller shall have no obligation to furnish such items.
Seller may retain copies of all or any parts of the files or other materials
so furnished, and all costs of copying such files shall be borne by Seller.
So long as such files or other materials so delivered by Seller to Buyer are
maintained by Buyer, Buyer shall permit Seller and its representatives to
have access to the same; for a period of three years after Closing Buyer
shall advise Seller before it destroys any such files or other materials (and
will, if requested by Seller, deliver to Seller any files or other materials
it intends to destroy).


                                    ARTICLE X

                         CERTAIN ACCOUNTING ADJUSTMENTS.


         SECTION 10.1. ADJUSTMENTS. Appropriate adjustments shall be made
between Buyer and Seller so that (a) all expenses (including, without
limitation, all drilling costs, all capital expenditures, and all overhead
charges under applicable operating agreements, and all other overhead charges
actually charged by third parties) which are incurred in the operation of the
Properties after the Effective Date will be borne by Buyer, and all proceeds
(net of applicable production, severance, and similar taxes) from sale of
oil, gas and/or other minerals produced from the Oil and Gas Properties after
the Effective Date will be received by Buyer, and (b) all expenses which are
incurred in the operation of the Properties before the Effective Date will be
borne by Seller and all proceeds (net of applicable production, severance,
and similar taxes) from the sale of oil, gas and/or other minerals produced
therefrom before the Effective Date will be received by Seller. It is agreed
that, in making such adjustments: (i) oil which was produced from the Oil and
Gas Properties and which was, on the Effective Date, stored in tanks located
on the Oil and Gas Properties (or located elsewhere but used to store oil
produced from the Oil and Gas Properties prior to delivery to oil purchasers)
and above pipeline connections shall be deemed

                                     -26-
<PAGE>

to have been produced before the Effective Date (it is recognized that such
tanks were not gauged on the Effective Date for the purposes of this
Agreement and that determination of the volume of such oil in storage will be
based on the best available data, which may include estimates), and (ii) ad
valorem taxes assessed with respect to a period which the Effective Date
splits shall be prorated based on the number of days in such period which
fall on each side of the Effective Date (with the day on which the Effective
Date falls being counted in the period after the Effective Date), and (iii)
no consideration shall be given to the local, state or federal income tax
liabilities of any party.

         SECTION 10.2.  CLOSING AND POST-CLOSING ACCOUNTING SETTLEMENTS.

         (a) At or before Closing, the parties shall determine, based upon
the best information reasonably available to them, the amount of the
adjustments provided for in SECTION 10.1. If the amount of adjustments so
determined which would result in a credit to Buyer exceed the amount of
adjustments so determined which would result in a credit to Seller, Buyer
shall receive a credit, for the amount of such excess, against the Preferred
Portion of the Purchase Price, and, if the converse is true, the Preferred
Portion of the Purchase Price shall be increased by the amount of such
excess. If no adjustment of the type contemplated under this SUBSECTION (a)
is made at or before Closing and Seller should thereafter receive any net
proceeds attributable to oil or gas produced after the Effective Date, Seller
shall promptly remit such net proceeds to Buyer.

         (b) On or before 90 days after Closing, Buyer and Seller shall
review any additional information which may then be available pertaining to
the adjustments provided for in SECTION 10.1, shall determine if any
additional adjustments (whether the same be made to account for expenses or
revenues not considered in making the adjustments made at Closing, or to
correct errors made in such adjustments) should be made beyond those made at
Closing, and shall make any such adjustments in the manner provided in
SUBSECTION (a) above. Following such additional adjustments, no further
adjustments shall be made under this ARTICLE X.


                                   ARTICLE XI

                         ASSUMPTION AND INDEMNIFICATION


         Seller agrees, as of the date of Closing (and, upon the execution
and delivery of the Assignments by Seller, Seller shall be deemed to have
agreed), to indemnify, defend and hold Buyer and its shareholders, directors,
officers, employees and agents harmless from and against any and all claims,
actions, liabilities, losses, damages, costs or expenses (including court
costs and attorneys' fees) of any kind or character arising out of or
otherwise relating to the ownership and/or operation of the Properties before
the Effective Date; provided, however, that the Seller's indemnification
obligation under this ARTICLE XI with respect to claims arising under
Environmental Laws shall extend only to conditions as they exist on the
Properties as of the Effective Date and to events giving rise to such
conditions which occurred prior to the Effective Date and shall terminate and
expire on the second anniversary date of this Agreement, except as

                                     -27-
<PAGE>

to any such claim made hereunder prior to such date. Buyer agrees, as of the
date of Closing (and, upon the execution and delivery of the Assignments by
Seller, Buyer shall be deemed to have agreed), (a) to assume, and to timely
pay and perform, all duties, obligations and liabilities relating to the
ownership and/or operation of the Properties after the Effective Date
(including, without limitation, those arising under the contracts and
agreements described in ARTICLE II(c) and those discussed in SECTION 18.4),
and (b) to indemnify, defend and hold Seller, its partners and its and such
partners' parent and subsidiary companies and other affiliates, and its and
their respective shareholders, members, owners, directors, officers,
managers, employees and agents harmless from and against any and all claims,
actions, liabilities, losses, damages, costs or expenses (including court
costs and attorneys' fees) of any kind or character arising out of or
otherwise relating to the ownership and/or operation of the Properties after
the Effective Date. In connection with (but not in limitation of) the

         SECTION 12.1. INDEMNIFICATION FOR CERTAIN LAWSUITS. Subject to
SECTION 12.3 and the other terms and provisions hereof, Seller agrees, as of

         SECTION 12.2. INDEMNIFICATION FOR CERTAIN TITLE RELATED ITEMS.
Subject to SECTION 12.3 and the other terms and provisions hereof, Seller
agrees, as of the date of Closing (and, upon the execution and delivery of
the Assignments by Seller, Seller shall be deemed to have agreed), to
indemnify, defend and hold Buyer and its shareholders, directors, officers,
employees and agents harmless from and against any and all claims, actions,
liabilities, losses, damages, costs or expenses (including reasonable court
costs and attorneys' fees) of any kind or character arising out of or
otherwise relating to the following:

         (a) claims and demands affecting or relating to the interest of
Seller in and to the Lake Cherokee Gas Unit, as described in the Declaration
of Unitization dated December 7, 1983,

                                     -28-
<PAGE>

recorded in Volume 1511, page 1 of the Deed Records of Gregg County, Texas,
to the extent and only to the extent that such claims and demands arise by,
through or under Goldking Properties Co., a partnership, or any other
Goldking entity other than Goldking Oil and Gas Corp.; and

         (b) any Defect of the type described in SECTION 7.1(b)(i) or SECTION
7.1(b)(iv) with respect to that portion of the Property described in item 1
following the heading "Gregg and Rusk Counties, Texas" on EXHIBIT II attached
hereto.

         SECTION 12.3. CERTAIN PROVISIONS. Notwithstanding SECTION 12.1 or
SECTION 12.2 or anything else herein to the contrary:

          (a) In connection with any indemnification under SECTION 12.1, in
no event shall the amount of Seller's indemnification exceed the sum of the
amounts set forth in EXHIBIT 7.1(b)(i) attributable to the Oil and Gas
Properties affected by the suit, action or proceeding for which such
indemnification is given.

         (b) In connection with any indemnification under SECTION 12.2:

                  (i)  Buyer and Seller shall attempt to agree upon the
         amount of the indemnification;

                  (ii)  If Buyer and Seller are unable to agree upon the
         amount of the indemnification, and the Defect with respect to a
         given Oil and Gas Property relates to the NRI specified on EXHIBIT
         7.1(b)(i) for such Oil and Gas Property, then the amount of the
         indemnification shall equal X multiplied by Y, where "X" is the
         amount specified on EXHIBIT 7.1(b)(i) for such Oil and Gas Property,
         and where "Y" is the proportionate reduction in NRI (e.g., the
         amount by which the share of production to which Seller is actually
         entitled is less than the NRI specified for such Oil and Gas
         Property on EXHIBIT 7.1(b)(i), divided by such NRI specified on
         EXHIBIT 7.1(b)(i)); and

                  (iii) Notwithstanding SUBPARAGRAPHS (i) and (ii) above, in
         no event shall the amount of Seller's indemnification with respect
         to a given Oil and Gas Property exceed the amount specified on
         EXHIBIT 7.1(b)(i) for such Oil and Gas Property.

         (c)  Any indemnification under this ARTICLE XII shall be effected in
the following manner:

                  (i)   If the Note is still outstanding at the time of the
         indemnification, the outstanding principal amount of the Note shall
         be reduced on a dollar-for-dollar basis by the amount of the
         indemnification obligation (provided, that in connection therewith
         (A) first, the Preferred Portion of the Purchase Price shall be
         deemed reduced on a dollar-for-dollar basis; and (B) second, to the
         extent the indemnification obligation has not been fully

                                     -29-
<PAGE>

         offset pursuant to the immediately preceding CLAUSE (A), the Common
         Portion of the Purchase Price shall be deemed reduced on a
         dollar-for-dollar basis).

                  (ii)  If the Note has been converted at the time of the
         indemnification obligation, the number of Seller's Common Shares and
         Preferred Shares received hereunder shall be reduced as follows: (A)
         first, the number of Preferred Shares shall be reduced on a
         share-for-share basis in amount derived by dividing the amount of
         the indemnification obligation by $1.00 and (B) second, to the
         extent the indemnification obligation has not been fully offset
         pursuant to the immediately preceding CLAUSE (A) (the amount of the
         indemnification obligation not offset being called the "REMAINING
         PORTION"), the number of Common Shares shall be reduced on a
         share-for-share basis by the number of shares equal to the lesser of
         (1) the number of shares derived by dividing the Remaining Amount by
         the Average Closing Price and (2) the number of Common Shares into
         which the Note was converted hereunder.

         (d) Notwithstanding SUBSECTION (c) above, Seller shall have the
right to transfer and assign to Buyer additional oil and gas properties
located in the same general area as the Oil and Gas Properties (in this
Section, "SUBSTITUTE PROPERTIES"), which transfer and assignment would be in
lieu of, or in conjunction with, an adjustment under SUBSECTION (c) above. If
substitute properties are transferred and assigned to Buyer under this
SUBSECTION (d), the amount of the indemnification shall be offset by the
PV-10 Value (as defined below) of the substitute properties. Any transfer and
assignment by Seller under this SUBSECTION (d) shall, however, be subject to
the Buyer having (A) concurred in good faith with the PV-10 Value of the
substitute properties and (B) made a good faith determination that (1) Buyer
will receive good and defensible title to the substitute properties, (2)
there are no material environmental or similar liabilities associated with
the substitute properties and (3) there are no other matters or items that a
reasonable and prudent purchaser of oil and gas properties would consider as
materially adversely affecting the value of, or proposed operations on, the
substitute properties; such transfer and assignment by Seller shall also be
further subject to receipt by Buyer of the concurrence of its lender under
the Senior Credit Facility as to the PV-10 Value of the substitute properties
and lender's approval of the substitute properties as acceptable additional
collateral for the Senior Credit Facility. As used in this SUBSECTION (d),
the term "PV-10 VALUE" shall mean, when used with respect to any substitute
properties, the pre-income tax value of projected net revenues (utilizing a
10% discount factor) from Proved Reserves (as defined in the definition for
Oil and Gas Reserves promulgated by the Society of Petroleum Engineers, or
any generally recognized successor) attributable to such substitute
properties as set forth in an Approved Reserve Report. As used in this
SUBSECTION (d), the term "APPROVED RESERVE REPORT" shall mean a reserve
report prepared in accordance with customary and generally accepted standards
and practices for petroleum engineers, and shall be based on prices, costs
and other assumptions as shall be designated by Seller and approved by Buyer
(which approval shall not be unreasonably withheld. The petroleum engineer or
engineers that prepare an Approved Reserve Report shall be designated by
Seller and approved by Buyer (which approval shall not be unreasonably
withheld).

<PAGE>

         (e) In connection with any indemnification under this ARTICLE XII,
the amount of such indemnification insofar as it pertains to a given Oil and
Gas Property, shall be reduced by the amount of the net cash flow received by
Buyer from such Oil and Gas Property from the Effective Date until the date
the indemnification is effected hereunder.

         (f) Seller shall retain full and complete control of the defense of
any of the suits, actions or proceeding listed in EXHIBIT 4.6. However,
amounts expended by Seller to date or hereafter in connection with the
defense of a suit, action or proceeding listed in EXHIBIT 4.6 (including
reasonable attorneys' fees and expenses and amounts paid in settlement of
such suit, action or proceeding or arising from a judgment against Seller (or
an affiliate thereof) in respect of such suit, action or proceeding, shall
not be applied against, and shall not be deemed to offset, the maximum amount
of any indemnification owed by Seller to Buyer under this ARTICLE XII in
respect of such suit, action or proceeding.

         (g) Seller's indemnification obligation under SECTION 12.2 shall
expire and terminate on the second anniversary date of this Agreement, except
as to any claim for indemnification under such Section made by Buyer prior to
such date. Further, Buyer agrees not to assert any claim for indemnification
under SECTION 12.2 prior to September 1, 1998.

         (h) Any claim by Buyer for indemnification under this ARTICLE XII
must be given in writing to Seller and shall specify in reasonable detail the
grounds for indemnification and the amount of indemnification sought.

         SECTION 13.1. SHARES ISSUABLE UPON CONVERSION. Upon receipt by Buyer
of the Vancouver Exchange Acceptance and the Preferred Share Approval, the
Note shall automatically be converted into a combination of Common Shares and
Preferred Shares determined as set forth below.

                  (i) The number of Common Shares to be issued upon conversion
         of the Note shall be equal to the Common Portion of the Purchase Price
         divided by the Average Closing Price.

                  (ii) The number of Preferred Shares to be issued upon
         conversion of the Note shall be equal to the Preferred Portion of the
         Purchase Price divided by $1.00.

In connection with the foregoing, it is specifically agreed by the parties
that upon conversion of the Note (A) any accrued but unpaid interest on the
Note existing on the date of conversion (in this Section, "ACCRUED INTEREST")

if, on the first Quarterly Payment Date, Buyer has the right to elect to make
a Payment in Kind (as such term is used in EXHIBIT 2.1--PREFERRED SHARES),
Buyer may also include the accrued interest as a part of the Payment in Kind.

         SECTION 13.2. DELIVERY OF NOTE; ISSUANCE OF SHARES. Upon the
conversion of the Note into Shares as provided in SECTION 13.1, Seller shall
surrender the Note, duly endorsed to Buyer, or in blank and accompanied by
proper instruments of transfer to Buyer, at its address set forth herein.
Promptly thereafter (and in any event no later five days after receipt by
Buyer of the Note), Buyer shall issue and deliver to Seller certificates for
the number of full Common Shares and full Preferred Shares to which Seller
shall be entitled. Buyer shall not be required to issue fractional shares of
Common Shares upon conversion of the Note. As to any final fraction of a
Common Share which Seller would otherwise be entitled to receive upon
conversion of the Note, Buyer shall pay a cash adjustment in respect of such
final fraction in an amount equal to the same fraction of the Average Closing
Price.

         SECTION 18.1. SURVIVAL OF PROVISIONS. All representations and
warranties made herein by Buyer and Seller shall be continuing and shall be
true and correct on and as of the date of

                                     -38-
<PAGE>

Closing with the same force and effect as if made at that time; further,
except as hereinafter provided, all of such representations and warranties
shall survive the Closing and the delivery of the Assignments.
Notwithstanding anything else herein to the contrary, the representations and
warranties contained in the following Sections shall not survive past the
Post-Closing Examination Point: SECTIONS 4.4 through 4.12 and SECTION 4.17.
The provisions of, and the obligations of the parties under, ARTICLE VII,
ARTICLE IX (to the extent the same are, by mutual agreement, not performed at
Closing), and ARTICLES X through XVIII inclusive shall survive the Closing
and the delivery of the Assignments.

         SECTION 18.2. FURTHER ASSURANCES. From time to time after the
Closing, at the request of any party hereto and without further
consideration, Seller, on the one hand, and Buyer, on the other hand, shall
execute and deliver to the requesting party such instruments and documents

obligation) as such requesting party may reasonably request in order to
consummate more fully and effectively the transactions contemplated hereby.

         SECTION 18.3. BINDING EFFECT; SUCCESSORS AND ASSIGNS. The Agreement
shall be binding on the parties hereto and their respective successors and

Seller with respect to all gas imbalances. As a result of such succession
Buyer shall (i) be entitled to receive any and all benefits, including

otherwise be entitled to produce and receive by virtue of ownership of the
Oil and Gas Properties, which Seller would have been entitled to receive by
virtue of such positions and (ii) shall be obligated to suffer any detriments
(whether the same be in the form of obligations to deliver production which
would have otherwise been attributable to its ownership of the Oil and Gas
Properties without receiving full payment therefor, or be in the form of the
obligation to make payment in cash) which Seller would have been obligated to
suffer by virtue of such positions.

other than an occasional sale, Buyer agrees to be solely responsible, and
shall indemnify and hold Seller (and their respective partners, and

sales or transfer taxes or fees (including related penalty, interest or legal
costs) due by virtue of this transaction on the Properties transferred
pursuant hereto and Buyer shall remit such sales or transfer taxes at that
time. Seller and Buyer agree to cooperate with each other in demonstrating
that the requirements for an occasional or isolated sale or any other sales
tax exemption have been met.

         (c) Buyer shall be solely responsible for all filings and recordings
of assignments and other documents related to the Properties and for all fees
connected therewith, and Buyer shall furnish Seller with 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.

         SECTION 18.6. ENTIRE AGREEMENT. This Agreement contains the entire
understanding of the parties hereto with respect to subject matter hereof and

provisions of this Agreement, and shall be entitled to enforce specifically
the provisions of this Agreement, in any court of the United States or any
state thereof having jurisdiction, in addition to any other remedy to which

DOES EXPRESSLY WAIVE THE PROVISIONS OF THE TEXAS DECEPTIVE TRADE

OF BUYER REGARDING VANCOUVER EXCHANGE ACCEPTANCE AND PREFERRED SHARE
APPROVAL. Buyer hereby represents and warrants to Seller that Buyer has
received Vancouver Exchange Acceptance. Buyer has informed Seller that as of
the date hereof Buyer only has the requisite corporate authority under its
charter documents to issue the Common Shares contemplated hereby upon
conversion of the Note, but not the Preferred Shares. Buyer represents and
warrants to Seller that the only actions necessary for Buyer in connection
with obtaining the approval of the issuance of Preferred Shares to Seller
upon conversion of the Note are (1) to amend the charter documents of Buyer
to authorize the Preferred Shares (which will require approval of both the
board of directors and shareholders of the Company) and (2) to authorize the
issuance of the Preferred Shares upon conversion of the Note (which will
require the approval of the board of directors of Buyer). The actions
described in the immediately preceding sentence are herein called the
"PREFERRED SHARE APPROVAL". Buyer covenants and agrees with Seller that the
Preferred Share Approval, as it relates to the actual terms and conditions of
the Preferred Shares, will be consistent with the terms, rights and
preferences set forth in EXHIBIT 2.1--PREFERRED SHARES and in a form
reasonably acceptable to Seller, and that Buyer will use its best efforts to
obtain the Preferred Share Approval as promptly as possible and, in any
event, no later than February 20, 1998. Buyer further represents and warrants
to Seller that it has no reason to believe that the Preferred Share Approval
will not be obtained by February 20, 1998. After receipt of the Preferred
Share Approval and the Vancouver Exchange Acceptance and upon request of
Seller, Buyer agrees to provide an opinion of legal counsel, which opinion
and legal counsel shall be reasonably acceptable to Seller, substantially to
the effect that the Preferred Share Approval and the Vancouver Exchange
Acceptance have been obtained and that the Common Shares and the Preferred
Shares have been duly authorized and issued and are fully paid and
nonassessable and covering such other matters relating to the authorization
and issuance of such shares as Seller may reasonably request.

         SECTION 18.12. ADDITIONAL COVENANT AND AGREEMENT OF SELLER REGARDING
EXISTING AND NET WORTH. Seller covenants and agrees with Buyer (a) to
maintain its existence (and not liquidate and terminate) during the two-year
period commencing on the date hereof and (b) that during the aforementioned
two-year period, it will either (1) retain and not transfer the Note or the
Common Shares and Preferred Shares issuable upon conversion of the Note or
(2) if it sells or otherwise transfers the Note (except upon conversion
thereof) or the Common Shares and Preferred Shares upon conversion of the
Note (or a portion thereof) it will maintain

                                     -41-
<PAGE>

a net worth of not less than $2,500,000 (which net worth shall be computed
based on the fair market value of the assets of Seller).

         SECTION 18.13. GOVERNING LAW. This Agreement shall be governed by
and construed in accordance with the laws of the State of Texas.

         SECTION 18.14. COUNTERPARTS. This Agreement may be executed in
counterparts, all of which are identical and all of which constitute one and
the same instrument. It shall not be necessary for Buyer and Seller to sign
the same counterpart.

                                     ARTICLE 2.
                          PURCHASE PRICE; PAYMENT; OPTION


       2.1    PURCHASE PRICE.  The total purchase price for the Subject
Interests shall be $5,478,098.00 (the "Purchase Price") payable in accordance
with the following terms:

              (a)    An initial payment shall be due and payable to Seller at
       Closing in an amount equal to $3,500,000.00 to be remitted as follows:
       (i) $133,862.00 to Seller; (ii) $3,366,138.00 for the account of Seller
       to Western Geophysical Company, each by wire transfer of immediately
       available funds.

              (b)    The second payment shall be due and payable to Seller on
       September 15, 1999, in an amount equal to $1,978,098.00 (the "Deferred
       Portion") to be remitted to Seller by wire transfer of immediately
       available funds; provided, however, in the event Buyer has not received
       on or before September 15, 1999, a fully executed Subordination Agreement
       in recordable form (the "Subordination Agreement"), the form of which is
       attached hereto as EXHIBIT F, Buyer shall pay only one-half of the
       Deferred Portion to Seller.  Subsequent to September 15, 1999, at the
       time Buyer receives the Subordination Agreement, Buyer shall use its best
       efforts as are reasonably practical under the circumstances to pay Seller
       as soon as possible the remaining one-half of the Deferred Portion, plus
       interest on said one half of the Deferred Portion at the prime rate, per
       annum in effect from time to time, which interest shall begin to accrue
       after September 15, 1999, but in all events such payment shall be made by
       Buyer to Seller within seven business days of Buyer's receipt of the
       Subordination Agreement.  Notwithstanding anything herein to the
       contrary, including the terms and provisions of Article 12, after Seller
       delivers to Buyer the Subordination Agreement and thereafter Buyer does
       not pay the Deferred Portion of the Purchase Price to Seller in the
       amount and within the time set forth herein, Seller, at its sole option,
       may elect to either (i) enforce its rights to receive the Deferred
       Portion of the Purchase Price or (ii) receive from Buyer an assignment of
       the Subject Interests, including the Seismic Data, (in the same form as
       the Assignment attached hereto as EXHIBIT E) conveyed to Buyer at
       Closing, such reconveyance to Seller to be free and clear of all liens
       and burdens placed thereon after Closing, for and in consideration of
       return from Seller to Buyer of the portion of the Purchase Price actually
       paid by Buyer for the Subject Interests, without interest, and (iii)
       pursue any other available legal or equitable remedies insofar as same
       relate to the elections Seller makes in either (i) or (ii) above.  In
       such event, Buyer agrees to pay all costs of pursuing such remedies
       incurred by Seller including reasonable attorneys fees, expenses and

       interest.  In addition, Buyer agrees to return the Seismic Data, destroy
       any notes or interpretations arising out of such data, and, from and
       after the reconveyance to Seller, maintain the data as a proprietary and
       confidential trade secret of Seller.

       2.2    OPTION.  The parties hereto recognize that Buyer is acquiring
37 1/2% of all of Seller's rights, titles and interests in the Properties.
In addition to the purchase of the Subject Interests and for the
consideration described below, Buyer also is acquiring and Seller hereby
grants to Buyer an option, at Buyer's sole election, to purchase an
additional 12.5% interest (the "Option Interest") of all of Seller's rights,
titles and interests in the Properties, including, without limitation, an
undivided twelve and one-half percent (12 1/2%) of all of the rights, titles
and interests which Seller acquired pursuant to the Acquisition Documents,
such percentage being calculated prior to the initial conveyance of the
Subject Interests, which means that after the purchase of the Subject
Interests hereunder and the Option Interest (if Buyer elects to purchase the
Option Interest), Buyer will have fifty percent (50%) of Seller's rights,
titles and interests in the Properties.  This option may be exercised by
payment by Buyer to Seller on or before February 25, 2000, of an amount of
$1,826,033.00 plus an additional amount of $214,276.00 payable in a manner
mutually agreed to by Seller and Buyer.  In the event that the parties cannot
mutually agree as to a manner of payment, Buyer shall pay Seller by wire
transfer in immediately available funds.  During the period from the Closing
hereof until February 25, 2000, Buyer shall make any payments for drilling,
completion, re-working, logging, testing, lease operating, oil and gas lease
acquisition, geophysical option acquisition, independent landman fees, and
title examination and opinion fees that are required of Seller and relate to
the Option Interest; provided, however, in the event Buyer notifies Seller
that Buyer is relinquishing the Option Interest, Buyer's obligation to make
said payments shall cease on the fifth day following Seller's receipt of said
notice. Upon exercise by Buyer of the Option Interest and payment therefore
to Seller, Seller will execute and deliver to Buyer an Assignment of the
Properties covered by the Option Interest using a form substantially similar
to the one attached hereto as EXHIBIT E.  All of Seller's representations,
warranties and covenants contained in this Agreement shall apply to the
Option Interest.  The Option Interest may not be transferred or assigned by
Buyer without the express written consent of Seller, which consent may be
withheld, except that Seller does hereby consent to such a transfer or
assignment by Buyer to an entity in which the general partner of Elliot
Associates, L.P. has an interest.

execution, delivery, and performance by Seller of this Agreement and each
other agreement, instrument, or document executed or to be executed by Seller

terms; (B) Seller is not in material breach or default with respect to any of

       3.16   [THIS SECTION INTENTIONALLY LEFT BLANK]

have been initiated by Seller.  Seller has initiated a reorganization of a
portion of its debt with certain creditors.  Seller has made available for
review to Buyer true and correct copies of all documents and instruments
related to such reorganization.

       execute and receive:

                     (1)    this Agreement

                     (2)    an Assignment and Bill of Sale (the "Assignment")
              in substantially the form annexed hereto as EXHIBIT E, with the

              (c)    Except for the Seismic Data, Seller shall deliver to Buyer

                         ASSUMPTION OF CERTAIN OBLIGATIONS


Upon and after Closing, Buyer shall own the Subject Interests, together with

including the Assumed Obligations.  Buyer agrees to assume and pay, perform,
fulfill and discharge all Assumed Obligations arising from and after the

                                       10
<PAGE>

Closing Date; including, but not limited to, the obligations to make payments
on behalf of Seller in accordance with Section 2.2.


                                     ARTICLE 9.
                    OPERATIONS; NO REDUCTION OF BUYER'S INTEREST


       9.1    OPERATOR.  It is understood and agreed that, unless otherwise
required by the Unitization Agreement or any other agreement to which the
Subject Interests are subject (the Unitization Agreement and each such other
agreement being hereinafter in this Section 9.1 referred to individually as a
"Third Party Agreement"), Buyer shall be the Operator for the drilling and
operation of all wells hereafter drilled on the Properties.  In the event a
Third Party Agreement provides for the selection of an Operator, Seller shall
vote and take all such other necessary actions as are reasonably practical
under the circumstances under such Third Party Agreement to select Buyer as
the Operator under such Third Party Agreement.  With respect to any portion
of the Properties in which the oil, gas and mineral leasehold estate therein
is owned solely by Seller and Buyer, operations on such portion of the
Properties shall be conducted pursuant to the Operating Agreement, with Buyer
as the Operator. Notwithstanding anything to the contrary contained in this
Purchase and Sale Agreement, Seller shall not be required to vote or take any
action to approve or maintain Buyer as Operator in the event Buyer does not
adequately fulfill its obligations as a reasonably prudent Operator under the
same or similar circumstances as more particularly set forth in the Operating
Agreement; or if Seller or another party to the Operating Agreement initiates
an action to remove Buyer as Operator for good cause as more particularly set
forth in the Operating Agreement.  Additionally, the parties agree that this
Article 9.1 shall be stated in the Operating Agreement.

       9.2    AVOIDANCE OF REDUCTION OF BUYER'S INTEREST.  The Mobil Term
Assignment provides that upon the occurrence of certain events that the
Assignee under said Assignment may be required to reassign to the Assignor
under said Agreement portions of the assigned premises not producing in
paying quantities (all as more particularly set forth and defined in the
Mobil Term Assignment). Seller hereby covenants and agrees to and with Buyer,
that in the event Buyer's interest in the production of oil, gas and/or other
minerals in lands which Buyer  retained pursuant to the Mobil Term Assignment
is to be reduced for any reason as a result of the Unitization Agreement,
Seller shall execute an additional assignment or assignments to Buyer
covering a sufficient amount of Seller's interest in the Properties to
prevent such interests of Buyer from being reduced.

       9.3    NOTICE OF CONTRACTUAL RIGHTS.  Seller hereby covenants and
agrees to and with Buyer that at Closing Seller will execute and deliver to
Buyer a "Notice of Contractual Rights", in recordable form, which reflects
that Seller's interest in the Properties is burdened by the agreements and
covenants set forth in this Article 9.  In the event Seller obtains and
delivers to Buyer an amendment to the Mobil Term Assignment which renders the
reason for Article 9.2 unnecessary, Buyer shall execute and deliver to Seller
a release of said Notice of Contractual Rights.

fees, claims or proceedings of any nature relating to the ownership or

or circumstance involving Buyer, whether based on negligence or otherwise,
and occurring prior to the Closing Date; and

       (iv)   Any claims, losses, damages, lawsuits, liens, judgments, costs,
reasonable attorneys' fees, claims or proceedings of any nature made by third
parties, including any and all governmental agencies or entities, relating to
the ownership and operation of the Subject Interests occurring before the
Closing Date.

       10.2   BUYER'S INDEMNIFICATION OF SELLER.  Buyer agrees to indemnify
and hold harmless Seller and its shareholders, directors, officers, partners,
employees, and their agents and assigns, from and against any Loss of Seller
resulting from, based upon, or arising from, directly or indirectly:

       (i)    Any inaccuracy in, or breach any of the representations or
warranties of Buyer set forth in this Agreement;

       (ii)   Any other matter as to which Buyer in other provisions of this
Agreement has expressly agreed to indemnify Seller;

       (iii)  Any lawsuits, liens, judgments, costs, reasonable attorneys'
fees, claims or proceedings of any nature relating to the ownership or
operations of the Subject Interests and arising out of any act, transaction
or circumstance involving Seller, whether based on negligence or otherwise,
and occurring after the Closing Date; and

       10.3   NOTICE AND OPPORTUNITY TO DEFEND.  After receipt by any party
thereto (the "Indemnified Party") of notice of any demand, claim, or
circumstances that, with the lapse of time, could give rise to a claim, or
the commencement (or threatened commencement) of any action, proceeding, or
investigation, that in either case could give rise to a right to
indemnification pursuant to this Article 10 (an "Asserted Liability"), the
Indemnified Party will give the party that may become obligated to provide
indemnification under this Article 10 (the "Indemnifying Party") written
notice describing the Asserted Liability in reasonable detail and indicating
the amount (estimated, if necessary) of the Loss that has been or may be
suffered by the Indemnified Party.  After accepting in writing an obligation
to indemnify the Indemnified Party against the assumed liability, the
Indemnifying Party may defend, at its own expenses and by its own counsel,
any Asserted Liability, and the Indemnified Party will cooperate in such
defense against such Asserted Liability.  If the Indemnified Party fails to
defend the Asserted Liability with thirty (30) calendar days after notice
thereof (or sooner if the nature of the Asserted Liability so requires) or
contests its obligation to indemnify under this Agreement, the Indemnified
Party may pay, compromise, or defend such Asserted Liability for the account,
and at the expense of, the Indemnifying Party. Notwithstanding the foregoing,
neither the Indemnifying Party nor the Indemnified Party may settle or
compromise any claim over the objection of the other; provided, however, that
consent to settlement or compromise will not be unreasonably withheld.  In
connection with the defense of any claim, the Indemnified Party will make
available to the Indemnifying Party any books, records, or other documents
within its control that are necessary or appropriate for such defense.  In
addition, any Indemnifying Party will be subrogated to the rights of the
Indemnified Party with respect to the respective Loss.

       10.4   RECOVERABLE AMOUNT.  Neither Buyer nor Seller shall be entitled
to recover from Seller or Buyer, respectively, for any losses, costs,
expenses, or damages arising under this Agreement or in connection with or
with respect to the transactions contemplated in this Agreement any amount in
excess of the actual compensatory damages, court costs and reasonable
attorney fees, suffered by such party.  Buyer and Seller shall have no right
to recover punitive, special, exemplary and consequential damage arising in
connection with or with respect to the transactions contemplated in this
Agreement.

       10.5   NO SETTLEMENT IF ADVERSE IMPACT.  No person entitled to
indemnification hereunder or otherwise to damages in connection with or with
respect to the transactions contemplated in this Agreement shall settle,
compromise or take any other action with respect to any claim, demand,
assertion of liability or legal proceeding that could prejudice or otherwise
adversely impact the ability of the person providing such indemnification or
potentially liable for such damages to defend or otherwise settle or
compromise with respect to such claim, demand, assertion of liability or
legal proceeding.

       10.6   WAIVER OF BREACH.  Neither Seller nor Buyer shall have any
obligation or liability under this Agreement or in connection with or with
respect to the transactions contemplated in this Agreement for any breach,
misrepresentation or noncompliance with respect to any representation,
warranty, covenant or obligation if such breach, misrepresentation or
noncompliance shall have been expressly waived by the other party.

Texstar Petroleum, Inc.
1000 Louisiana, Suite 3950
Houston, Texas 77002


RE:  Sale of Wausau Pipeline System, A. Foote Estate #1 and Fairchild #1 Wells
     Wayne and Jones Counties, Mississippi


Dear Mr. Foster:

     Reference is made to the December 14, 1998 letter of intent by Texstar
offering to purchase the TransTexas eight-inch pipeline, and related
facilities, running from the TransTexas Foote Estate #1 well in Wayne County,
Mississippi to the Tennessee Gas Transmission Line in Jones County,
Mississippi, and the TransTexas A. Foote Estate #1 and Fairchild #1 wells.

     TransTexas is interested in selling the pipeline and wells subject to
general terms and conditions stated in your letter of intent, but altered as
set forth below:

     (i)    Cash consideration for the pipeline and wells in the amount of
            Four Hundred Twenty-five Thousand Dollars ($425,000) for
            TransTexas' right, title and interest (assumed to be 100% in the
            pipeline and a net revenue interest of 70% in each well);

     (ii)   Free gas transportation as set forth in paragraph 3 of your
            letter of intent is no longer necessary because Texstar will be
            buying the wells;

     (iii)  The execution by both parties of definitive conveyancing
            documents which set forth mutually acceptable terms and
            conditions of the transaction; and

     (iv)   The approval by the Board of Directors of TransTexas Gas
            Corporation.

     If the foregoing alterations to the provisions set forth in the Texstar
December 14, 1998 letter of intent represent acceptable revised general terms
and conditions for the purchase and sale of these assets, please sign in the
space provided below and return one executed copy to TransTexas.

                                       Very truly yours,

                                       /s/ Arnold Brackenridge

severally liable for the Allowed Amount of Participating Creditors' Claims.

       6.02   DEBT.  The full amount acknowledged by Texstar to be due and
owing to Participating Creditors as of June 14, 1999, is set forth in Exhibit

       6.03   ARBITRATION OF CLAIM AMOUNT DISPUTES.  Any claim by a
Participating Creditor that the Allowed Amount of its claim should be greater
than the amount listed on Exhibit 2 shall be resolved in accordance with this
Section.

              (a)    The Companies and the Participating Creditor in question
                     will attempt in good faith to resolve any controversy or
                     dispute concerning the amount owed promptly by negotiations
                     between themselves.  No arbitration may be commenced by any
                     party unless and until a negotiation complying with the
                     foregoing subparagraph has been completed.

              (b)    If a controversy or dispute with respect to the Allowed
                     Amount of a claim is not resolved after completion of the
                     negotiation process described above, then, upon notice by
                     any party to the other parties (an "Arbitration Notice")
                     and to the American Arbitration Association, the
                     controversy or dispute shall be submitted for binding
                     arbitration in Houston, Texas, in accordance with the
                     American Arbitration Association's Commercial Arbitration
                     Rules (the "Rules").  The parties agree that they will
                     abide by and perform any award rendered by the arbitrator.
                     The arbitration shall be governed by the Federal
                     Arbitration Act, 9 U.S.C. Section 1-16 (or by the same
                     principles enunciated by such Act in the event it may not
                     be technically applicable).  The determination of the
                     Allowed Amount of a claim by the arbitrator shall be

                                       11

<PAGE>

                     final and binding on all parties and judgment upon the
                     award or judgment of the arbitrator may be entered and
                     enforced by any court having jurisdiction.  The fees and
                     expenses of the arbitrator will be shared by all parties
                     engaged in the dispute or controversy on a basis determined
                     to be fair and equitable by the arbitrator, taking into
                     account the relative fault of each party, the relative
                     credibility and merit of all claims and defenses made by
                     each party and the cooperation, speed and efficiency of
                     each party in conducting the arbitration proceedings and
                     complying with the Rules and with orders and requests of
                     the arbitrator.

              (c)    Promptly after the Arbitration Notice is given, the
                     American Arbitration Association will select three possible
                     arbitrators that have experience in the oil and gas
                     business, to whom the American Arbitration Association will
                     give the identities of the parties and the general nature
                     of the controversy.  If any of those arbitrators
                     disqualifies himself or declines to serve, the American
                     Arbitration Association shall continue to designate
                     potential arbitrators until the parties have three to
                     select from.  After the panel of three potential
                     arbitrators has been completed, a two-page summary of the
                     background of each of the potential arbitrators will be
                     given to each of the parties, and the parties will have a
                     period of ten (10) days after receiving the summaries in
                     which to attempt to agree upon the arbitrator to conduct
                     the arbitration.  If the parties are unable to agree upon
                     an arbitrator, then one of the parties shall notify the
                     American Arbitration Association, and the American
                     Arbitration Association shall select the arbitrator from
                     one of the three, or less, if one or more has been found to
                     be disqualified or removes himself from consideration (if
                     all three are disqualified or remove themselves, then the
                     American Arbitration Association shall start the
                     arbitration selection process over again).  The decision of
                     the American Arbitration Association with respect to the
                     selection of the arbitrator will be final and binding in
                     such case.

              (d)    Within ten (10) days after the selection of the arbitrator,
                     the parties and their counsel will appear before the
                     arbitrator at a place and time in Houston, Texas, as may be
                     designated by the arbitrator for the purpose of each party
                     making a one hour or less presentation and summary of the
                     case.  Thereafter, the arbitrator will set dates and times
                     for additional hearings until the proceeding is concluded.
                     The desire and goal of the parties is, and the arbitrator
                     will be advised that his goal should be, to conduct and
                     conclude the arbitration proceedings as expeditiously as
                     possible.  If any party or his counsel fails to appear at
                     any hearing, the arbitrator shall be entitled to reach a
                     decision based on the evidence which has been presented to
                     him by the parties who did appear.  Any arbitral award may
                     be confirmed by a Texas state court.

              (e)    The amount of Participating Creditor claims shall be
                     adjusted pursuant to any arbitration award made pursuant to
                     this Agreement

Eligible Claim in an Allowed Amount greater than $10,000 may elect to reduce
the amount of such holder's claim to $10,000 and to receive treatment as a
Convenience Claim.  Such election shall constitute a waiver of the right to
collect, and a release of, the amount of the Eligible Claim in excess of
$10,000, and the holder of such claim shall be deemed to have released the
Companies and their property from any and all liability for such excess
amount.

              (l)    An event of default as to Benz shall constitute an event of

                                    ARTICLE XXIII

                                       REMEDIES

       23.01  DEFAULT BY BENZ OR TEXSTAR.  In addition to any other provision
of this Agreement or the Collateral Documents, upon the occurrence of an
Event of Default, the Collateral Agent may, upon ten (10) days written notice
to Aquila, exercise any or all of the following rights, remedies and recourse:

              a.     Enter upon the collateral or any part thereof and take
       exclusive possession thereof and of all books, records and accounts
       relating thereto.  If Benz or Texstar remains in possession of all or any
       part of the collateral after an Event of Default occurs and is continuing
       and without the Collateral Agent's prior written consent thereto, the
       Collateral Agent may invoke any and all legal remedies to dispossess the
       Companies, including specifically one or more actions for forcible entry
       and detainer, trespass to try title and writ of restriction.  Nothing
       contained in the foregoing sentence shall, however, be construed to
       impose any greater obligation or any prerequisites to acquiring
       possession of the collateral or any part thereof after an Event of
       Default occurs than would have existed in the absence of such sentence.

              b.     Hold, lease, manage, operate or otherwise use or permit the
       use of the collateral, or any part thereof, either by itself or by other
       persons, in such manner, for such time and upon such other terms as the
       Collateral Agent may deem to be prudent and reasonable under the
       circumstances (making such repairs, alterations, additions and
       improvements thereto and taking any and all other action with reference
       thereto, from time to time, as the Collateral Agent shall deem necessary
       or desirable), and apply all proceeds from the collateral in accordance
       with the provisions hereof.

              c.     Sell or offer for sale the collateral, or any part thereof,
       in such portions, order and parcels as the Collateral Agent may
       determine, with or without having first taken possession of same, in
       accordance with the provisions of the applicable Collateral Documents and
       applicable legal requirements.

              d.     Make application to a court of competent jurisdiction, as a
       matter of strict right and, except as otherwise provided by applicable
       law, without notice to the Companies or without regard to the adequacy of
       the collateral for payment of the obligations to the Collateral Agent
       hereunder for the appointment of a receiver of the collateral, or any
       part thereof, and, to the extent permitted by applicable law, the
       Companies do hereby irrevocably consent to such appointment.  Any such
       receiver shall have all the usual powers and duties of receivers in
       similar cases, including the full power to rent, maintain, sell, dispose
       and otherwise operate the collateral, any part thereof, upon such terms
       that may be approved by the court, and shall apply all proceeds from such
       operation of the collateral in accordance

                                       24

<PAGE>

       with the provisions hereof.

              e.     Exercise any and all other rights, remedies and recourses
       granted hereunder or under the Collateral Documents or otherwise now or
       hereafter existing in equity, at law, by virtue of statute or otherwise.

       23.02  The collateral may be sold in one or more parcels and in such
manner and order as the Collateral Agent, in its sole discretion, may elect,
it being expressly understood and agreed that the right of sale arising out
of any Event of Default shall not be exhausted by any one or more sales.

       23.03  The Collateral Agent shall have all rights, remedies and
recourses granted in the Collateral Documents, and available at law or equity
(including specifically those granted by the UCC in effect and applicable to
the collateral, or any portion thereof) and same (a) shall be cumulative and
concurrent, (b) may be pursued separately, successively or concurrently
against Benz or Texstar or against the collateral or against any one or more
of them, at the sole discretion of the Collateral Agent, (c) may be exercised
as often as the occasion therefor shall arise, it being agreed by the
Companies that the exercise or failure to exercise any of same shall in no
event be construed as a waiver or release thereof or of any other right,
remedy or recourse, and (d) are intended to be, and shall be, non-exclusive.

       23.04  The Companies shall not, except as otherwise provided by
applicable law, be relieved of their obligations by reason of (a) the failure
of a trustee to comply with any request of the Companies, to foreclose the
liens on the collateral or to enforce any provisions of the Collateral
Documents, (b) the release, regardless of consideration, of any person or
entity obligated with respect to the obligations, or of the collateral or any
part thereof, or the addition of any other property to the collateral, (c)
any agreement or stipulation between any subsequent owner of the collateral
and the Collateral Agent extending, renewing, rearranging or in any other way
modifying the terms of the Collateral Documents without first having obtained
the consent of, given notice to or paid any consideration to Benz or Texstar,
or such other person, and in such event, Benz or Texstar, and all such other
persons shall continue to be liable to make payments in accordance with the
terms of any such extension or modification agreement unless expressly
released and discharged in writing by the Collateral Agent, and (d) any other
act or occurrence, save and except the satisfaction of the Companies'
obligations hereunder.  The Companies waive any right to require the
Collateral Agent to proceed against any other person, exhaust any of the
collateral, or pursue any other remedy in the Collateral Agent's power.

       23.05  The release or substitution of all or any part of the
collateral, regardless of consideration, shall not in any way impair, affect,
subordinate, or release the Collateral Agent's liens or its priority status
in and to any remaining collateral.  For payment and performance of the
Companies' obligations hereunder, the Collateral Agent may resort to any
other security therefor held by a trustee in such order and manner as the
Collateral Agent may elect.

       23.06  In case the Collateral Agent shall have proceeded to invoke any
right, remedy or recourse permitted under the Collateral Documents and shall
thereafter elect to discontinue or abandon same for any reason, the
Collateral Agent shall have the unqualified right to do so and, in

                                       25

<PAGE>

such event, the Companies and the Collateral Agent shall be restored to their
former positions with respect to the Companies' obligations hereunder, the
Collateral Documents, the collateral and otherwise, and the rights, remedies,
recourses and powers of the Collateral Agent shall continue as if same had
never been invoked.

       23.07  NO ELECTION OF REMEDIES.  The Participating Creditors shall
have all rights, remedies and recourses granted in the Collateral Documents,
and available at law or equity and same (a) shall be cumulative and
concurrent, (b) may be pursued separately, successively or concurrently
against the Companies or against the subject collateral or against any one or
more of them, at the sole discretion of the Collateral Agent, (c) may be
exercised as often as the occasion therefor shall arise, it being agreed by
the Companies that the exercise or failure to exercise any of same shall in
no event be construed as a waiver or release thereof or of any other right,
remedy or recourse, and (d) are intended to be, and shall be, non-exclusive.

       23.08  DEFAULT BY A PARTICIPATING CREDITOR.  The representations,
warranties and covenants of the Participating Creditors are several and not
joint.  Should an Event of Default as to a Participating Creditor occur, (i)
the defaulting Participating Creditor shall remain obligated to perform its
obligations under this Agreement including those set forth in Article XVII,
(ii) the rights of all parties other than the defaulting Participating
Creditor shall be unaffected, (iii) the Companies may suspend making any
further payments to the defaulting Participating Creditor until such time as
the damages incurred by the default are recovered, and (iv) the Participating
Creditors shall be liable for any actual damages sustained as a result of its
default.

       23.09  DEFAULT BY COLLATERAL AGENT. Should an Event of Default as to
the Collateral Agent occur (i) the Collateral Agent, to the extent permitted
by the Collateral Agent Agreement, shall be liable for the actual damages
sustained as a result of his willful misconduct and/or fraud, and (ii) the
total amount of Participating Creditor Claims shall be reduced Pro Rata by
the damages sustained by the Companies.

                                     ARTICLE XXIV

aggregate of all interest and any other charges constituting interest under
the

                                       29

<PAGE>

applicable law contracted for chargeable or receivable under this Agreement
and the Collateral Documents or otherwise in connection with this transaction
shall under no circumstances exceed the maximum amount of interest permitted
by law.  If any excess of interest or in such respect is provided for or
shall be adjudicated to be so provided for in this Agreement and the
Collateral Documents or in any of the documents securing payment hereof or
otherwise relating hereto, then in such event,

              (a)    The provisions of this paragraph shall govern and control;

              (b)    The Companies shall not be obligated to pay the amount of
       such interest to the extent that it is in excess of the maximum permitted
       by law;

              (c)    Any excess of said interest shall be deemed a mistake and
       is hereby canceled automatically and if theretofore paid, shall at the

              (d)    The effective rate of interest shall be automatically
       subject to reduction to the maximum lawful contract rate allowed under
       said laws or as is or as they may hereafter be construed by courts of
       appropriate jurisdiction.  To the extent permitted by law, the
       determination of the rate of interest shall be made by amortizing,
       prorating, allocating, and spreading in equal parts during the period of
       the full stated term of the loan, all interest at any time contracted
       for, charged, or received from the Companies in connection with said
       loan.

8.1; and

         (b)      statutory liens for taxes, statutory mechanics' and
materialmen's liens incurred in the ordinary course of business, and other
similar liens incurred in the ordinary course of business, provided such
liens do not secure Indebtedness and secure only Liabilities which are not
delinquent or which are being contested as provided in SECTION 7.6.

         SECTION 8.3. LIMITATIONS ON INVESTMENTS AND NEW BUSINESSES. Neither
Seller nor any Subsidiary will engage directly or indirectly in any business
other than the oil and gas exploration and development business.

         SECTION 8.4. TRANSACTIONS WITH AFFILIATES. Neither Seller nor any

         SECTION 8.5. LIMITATION ON DIVIDENDS AND REDEMPTIONS. Neither Seller
nor any of its Subsidiaries will declare or pay dividends on, or make any
other distribution in respect of, any class of its capital stock or any
partnership or other interest in it, nor will Seller or any Subsidiary
directly or indirectly make any capital contribution to or purchase, redeem,
acquire or retire any shares of the capital stock of or partnership interests
in Seller or any Subsidiary, or cause or permit any reduction or retirement
of the capital stock of Seller or any Subsidiary, except as otherwise
expressly provided in this Section. Such dividends, distributions,
contributions, purchases, redemptions, acquisitions, retirements or
reductions may be made by Seller: (a) without limitation to Seller; (ii) to
Subsidiaries of Seller, to the extent permitted under this SECTION 8.3; and
(iii) as required under the terms of Seller's Class A Series I Convertible
Preferred Stock, including the Preferred Shares, and Seller's Class A Series
II Convertible Preferred Stock. Seller or any Subsidiary thereof may declare
and pay to any Person dividends payable only in its common stock, so long as
Seller's interest in any of its Subsidiaries is not thereby reduced.

         SECTION 8.6. CERTAIN CONTRACTS; AMENDMENTS; MULTIEMPLOYER ERISA
PLANS. Neither Seller nor any Subsidiary thereof will, directly or
indirectly, enter into, create, or otherwise allow to exist any contract or
other consensual restriction on the ability of any Subsidiary of Seller to:
(a) pay dividends or make other distributions to Seller; (b) to redeem equity
interests held in it by Seller; (c) to repay loans and other indebtedness
owing by it to Seller; or (d) to transfer any of its assets to Seller. No
ERISA Affiliate will incur any obligation to contribute to any "multiemployer
plan" as defined in Section 4001 of ERISA.

         SECTION 8.7. COVERAGE RATIO. The Coverage Ratio will never be less
than 1.4 to 1. As used in this Section, the term "COVERAGE RATIO" shall mean
Tangible Assets of Seller divided by Long Term Debt of Seller. As used in
this Section: (a) the term "TANGIBLE ASSETS" shall mean the sum of: (i) the
present value (utilizing a 10% discount rate) of the estimated proved
reserves; (ii) cash; (iii) securities; and (iv) net book value of unproved
properties and equipment as if Seller were following the full cost method of
property accounting beginning January 1, 1999, and (b) the term "LONG TERM
DEBT" shall mean long-term debt as the same is defined in Seller's audited
financial statements. For purposes hereof, the Coverage Ratio will be
calculated no later than April 15 of each year as of December 31 of the
previous year using Seller's audited fiscal year-end audited financial
statements and year end estimates of proved reserves by Seller's independent
engineers.

approved in writing by the Lender. Development Loan proceeds may be used by the
Borrower for the purposes of funding the Borrower's share of costs and expenses
relating to the conduct of the Development Operations described on
SCHEDULE 2.1(b) hereof, or such other development operations as may be
subsequently approved in writing by the Lender. The Borrower shall also be
allowed to pay with Development Loan proceeds to the extent permissible under
applicable law, any mortgage filing fees which may be required to properly file
any and all Security Documents.

Borrower shall repay the Loans plus all interest accrued thereon by the Loan
Termination Date. Provided that no Unmatured Event of Default or Event of
Default exists or would result therefrom, the Borrower shall repay the EnCap
Junior Note at the stated maturity thereof.

         Section 2.4 PREPAYMENT OF THE LOANS. The Borrower, from time to time
after the Closing Date and without premium or penalty, may prepay the Advancing
Note, in whole or in part. Other than from the proceeds from the sale of, or
exercise of remedies with respect to, the "EnCap Properties" (as defined in the
Assignment of Junior Note and Liens) the Borrower may not prepay the EnCap
Junior Note without the prior written consent of the holder of the Advancing
Note, in which event the Borrower may prepay the EnCap Junior Note without
premium or penalty to the extent provided in such consent. Any principal prepaid
pursuant to this section shall be in addition to, and not in lieu of, all
payments otherwise required to be paid under the Loan Documents at the time of
such prepayment, including any Swap Settlement Payables associated with any Swap
Agreement that must be terminated as a result of such prepayment. If the
Borrower (i) prepays any principal pursuant to this SECTION 2.4 and (ii) elects
to maintain in effect any Swap Agreement not required to be terminated as a
result of such prepayment, the Security Documents securing the Borrower's
obligation to pay any Swap Settlement Payables associated with any such Swap
Agreement shall remain in force and effect (and shall be promptly amended by the
Borrower and the Lender to the extent necessary) so long as any Swap Agreements
remain outstanding. Similarly, in the event of any such prepayment after which
any Swap Agreement remains outstanding, the Borrower shall be entitled to
receive and retain any Swap Settlement Proceeds associated with the relevant
Swap Agreement, subject to the terms of any applicable Security Documents.

         Section 2.5 COMMENCEMENT OF OVERRIDING ROYALTY INTEREST PAYMENTS. The
Overriding Royalty Interest will be applicable with respect to all oil, gas and
other minerals produced, saved and sold or used off the premises of the relevant
Lease or Unit from or attributable to the Properties from the first day of the
calendar month following the Loan Termination Date. The Borrower may purchase
the Overriding Royalty Interest from the Lender in accordance with SECTION 8.4.

production is sold to someone other than Aquila or an Affiliate of Aquila; and
(ii) all direct lease operating costs, transportation, processing and marketing
costs, ad valorem and severance taxes, royalties and overriding royalties with
respect to each Property, together with such other detailed information as is
prescribed in the form of Property Operating Statement attached hereto as
EXHIBIT C. The first Property Operating Statement shall be delivered on
September 20, 1999, and, excluding any payments made pursuant to the properties
acquired pursuant to the Shell Transaction, will detail Gross Receipts
attributable to the production of Hydrocarbons from the Properties during the
month of August, 1999, and Operating Expenses, Direct Taxes, royalties,

Gross Receipts reflected in the relevant Property Operating Statement and Gross
Receipts relating to production sold to Aquila and its Affiliates shall be
applied as follows:

                  (a) First, to the Borrower, for payments of such sums, the
         amount necessary to pay the Operating Expenses, Direct Taxes,
         royalties, overriding royalties and other interests payable out of or
         measured by production, if any, associated with the Properties, and

         reflected in the relevant Property Operating Statement;

                  (b) Second: (i) eighty-five percent (85%) of the Base Net
         Revenue; and (ii) fifty percent (50%) of the Excess Net Revenue, as
         reflected in the relevant Property Operating Statement and the records
         of the Lender and its Affiliates (in the case of production sold to the
         Lender and its Affiliates), to the Lender for payment of amounts which
         are included within Advancing Note Debt Service and other Obligations
         payable to the holder of the Advancing Note for the relevant Interest
         Period. The percentage stated in clause (i) of the preceding sentence
         shall be known as the "BASE DEDICATION RATES" and the percentage stated
         in clause (ii) of the preceding sentence shall be known as the "EXCESS

         the Base Dedication Rate shall be one hundred percent (100%) and upon
         the occurrence and during the continuation of any other Event of
         Default the Base Dedication Rate shall be ninety-five percent (95%).
         The amount paid to the Lender pursuant to this subpart (b) shall be
         applied first to any interest due on the Advancing Note until all
         accrued interest is paid in full, and any remaining amounts paid to the
         Lender pursuant to this subpart (b) shall be applied to remaining
         principal of the Advancing Note; and

                  (c) Third, any remaining amount of Gross Receipts properly
         reflected in the relevant Property Operating Statement shall be paid to

         Section 2.7 BORROWER SUB-ACCOUNT.

                  (a) Until the Loan Termination Date, the Borrower shall, and
         shall cause each Operator to, direct and cause all Purchasers of
         Hydrocarbons, to deposit all payments of any nature whatsoever due and
         owing by such Persons with respect to the Properties or Hydrocarbons
         produced therefrom to the Borrower directly into the Cash Collateral
         Account; provided, however, that Purchasers of Hydrocarbons may make
         distributions to royalty interest owners and third-party working
         interest owners and may withhold severance taxes. The Cash Collateral
         Account shall be administered in accordance with the terms of the Cash
         Collateral Account Agreement. The Lender shall establish a sub-account
         (the "BORROWER SUB-ACCOUNT") on its internal books and records and
         shall credit to such the Borrower Sub-Account all collected funds which
         constitute payments referred to in the preceding SECTION 2.6. The
         Borrower authorizes the Lender to debit the Borrower Sub-Account for
         the payment of all Obligations hereunder when due and payable,
         including all amounts paid by the Lender pursuant to SECTION 8.2, and
         including any such debit that would cause the Borrower Sub-Account to
         be in a negative status.

                  (b) On each Repayment Date, and after satisfying all
         distributions to the Lender pursuant to SECTION 2.6, the Lender will
         release or cause to be released to the Borrower from the Cash
         Collateral Account an amount of funds from amounts credited to the
         Borrower Sub-Account in order to pay the expenses provided for in
         SECTION 2.6(a) incurred for the preceding calendar month, plus an
         amount equal to the difference between one hundred percent (100%) of
         Net Revenue and the sum of: (i) the product of the Base Dedication Rate
         and the Base Net Revenue; and (ii) the product of the Excess Dedication
         Rate and the Excess Net Revenue, such sum to be applied to repayment of
         the Advancing Note Debt Service pursuant to SECTION 2.6 hereof ("NET
         REVENUE REIMBURSEMENT AMOUNT"). The Borrower will have one hundred
         eighty (180) days after each receipt of such funds to contest the
         amount of funds released, after which time the amount released will be
         deemed conclusively correct.

                  Notwithstanding anything to the contrary contained herein and
         regardless of whether any Event of Default exists hereunder, any
         amounts deposited into the Cash Collateral Account owing to third party
         working interest and royalty interest holders or to taxing authorities
         for Severance Taxes and Property Taxes shall be released by the Lender
         to the Borrower within five (5) Business Days after receipt of a
         certificate from the Borrower or such other Person (which may, but need
         not, be an Affiliate of the Borrower) as Borrower may designate on no
         less than ten (10) Business Days prior written notice to the Lender,
         which certificate details such amounts and the party to be paid so that
         the Borrower may return such amounts to such third party working
         interest and royalty interest holders and taxing authorities. The
         Lender shall have the right to undertake audit procedures during normal
         business hours and upon prior written notice to confirm periodically
         that the Borrower or any such designee on behalf of the Borrower has
         paid all obligations for which funds were released to the Borrower or
         any such designee as Net Revenue Reimbursement Amounts. The Lender
         shall have the right at its option, but not the obligation, to make
         such payments directly from the Cash Collateral Account to the third
         party working interest and royalty interest holders and taxing
         authorities upon the occurrence of and during the continuance of an
         Event of Default


                                      19
<PAGE>

         hereunder; provided that if the Lender elects not to make such
         payments, The Lender shall release such funds to the Borrower to
         make payments to third party working interest and royalty interest
         holders and taxing authorities.

         Section 2.8 PURCHASERS OF PRODUCTION. The Borrower shall notify the
Lender promptly of any changes to the list of Persons who purchase Hydrocarbons
produced from or allocated to the Properties, as set forth on SCHEDULE 2.8
attached hereto, if, as and when any change occurs in the Persons who purchase
such Hydrocarbons.

         Section 2.9 MANDATORY PREPAYMENT OF THE LOANS. The Borrower shall pay
promptly to the Lender the product of the Base Dedication Rate multiplied by all
proceeds of sales of any assets of the Borrower (except to the extent proceeds
of sales of Equipment are utilized within 60 days of such sale to purchase
replacements of such Equipment) that comprise any part of the Collateral and not
otherwise constituting Gross Receipts and paid into the Cash Collateral Account
(provided, however, that this provision is subject to SECTION 7.2(a) and shall
not be deemed to be a consent by the Lender to any such sale). All proceeds of
any such sale shall be immediately applied to repayment of the Loans and accrued
interest thereon in accordance with SECTION 2.6(b) hereof.

         Section 2.10 INITIAL SWAP AGREEMENT. At Closing, the Borrower and the
Lender shall enter into a Swap Agreement in form and substance mutually

reasonably requests for the purpose of perfecting, confirming, protecting or
establishing the priority of any Liens or other rights in the Collateral
securing any Obligations.

full by the Borrower of all Obligations under the Loan Documents, other than the
Overriding Royalty Interest Conveyance, the Lender shall deliver or cause to be
delivered to the Borrower, at the Borrower's expense, releases and satisfactions
of all financing statements, mortgages and other


                                      20
<PAGE>

registrations of security with respect to the Collateral and the Borrower
shall deliver to the Lender a general release of all of the Lender's
liabilities and obligations under the Loan Documents, other than the

the Borrower's Net Revenue Interests in the Properties will receive notification

         party on its behalf in connection with the obtaining of the credit
         facility provided for in this Agreement or in connection with the
         business transactions giving rise to the Borrower's seeking such credit
         are, taken as a whole, complete and accurate in all material respects
         and contain no material omission or misstatement. The Initial Reserve

         Engineers. The Initial Reserve Report is based on historical
         information which, to the best of the Borrower's knowledge, is complete
         and accurate in all material respects and contains no material omission
         or misstatement; provided, however, that the Borrower makes no
         representation or warranty regarding the accuracy of the forecasts,
         projections or quantity of reserves or producibility thereof reflected
         by such Initial Reserve Report;

                  (q) HOLDING COMPANY. The Borrower is not a "holding company"
         or a "subsidiary company" of a "holding company" or an "affiliate" of a

         Public Utility Holding Company Act of 1935, as amended; and

                  (r) INVESTMENT COMPANY. The Borrower is not an "investment
         company" within the meaning of the Investment Company Act of 1940, as
         amended.

         compensation, stock option, bonus, consulting or retirement agreements
         or plans, or other employee benefit plans of any kind, including
         without limitation any pension or welfare benefit plans with any
         employee of Borrower whose employment is not terminable at-will. Except
         as disclosed on SCHEDULE 4.1(k), Borrower does not maintain nor has it

         Adverse Effect.

         Section 6.1 LOCATION: RECORDS. Except in the ordinary course of
business or as otherwise permitted by this Agreement or another Loan Document or
by the prior written consent of the Lender, all Equipment owned by or on behalf
of the Borrower will be kept at the Properties, and except that, so long as no
Unmatured Event of Default or Event or Default shall have occurred and be

of the applicable Operating Agreements and may dispose of obsolete, broken or
worn Equipment, in either case without the Lender's consent but upon prior
written notice to the Lender; provided that either (i) the proceeds of any such
disposition shall be used to purchase substantially similar Equipment or (ii)
the amount of the proceeds multiplied by the applicable Dedication Rate shall be
delivered to the Lender to be applied to the Obligations in accordance with

continuance of an Event of Default or an Unmatured Event of Default, the
Borrower may dispose of Equipment in accordance with the terms of the applicable
Operating Agreements only with the Lender's prior written consent upon ten (10)
days prior written notice to the Lender, which consent shall not be unreasonably
withheld. All of the records of the Borrower regarding the Equipment shall be
available during the Borrower's usual business hours to any officer, employee,
agent or representative of the Lender following reasonable advance written
notice from the Lender.

         Section 6.2 MAINTENANCE. The Borrower, acting in accordance with the
prudent operator standard, will keep its Equipment in a good state of repair and
good operating condition, will make repairs and replacements when and where
necessary, will not waste or destroy it or any part thereof, and will not be
negligent in the care or use thereof. The Borrower shall repair and maintain its
Equipment in a manner sufficient to continue the operation of the Properties.
The Borrower shall use its Equipment in accordance with Law and the
manufacturer's instructions.

         Section 6.3 DISPOSITIONS. Where the Borrower is permitted to dispose of
any Equipment under this Agreement or by prior written consent thereto hereafter
given by the Lender, the Borrower shall do so in an arm's length transaction, in
good faith and by obtaining the maximum amount of recovery practicable therefor
and without impairing the operating integrity of its remaining Equipment or the
Properties.

                        ARTICLE 7: COVENANTS OF BORROWER

         Section 7.1 AFFIRMATIVE COVENANTS. The Borrower warrants, covenants and
agrees that until full and final repayment of the Obligations and the

covenants:

                  (a) PAYMENT AND PERFORMANCE. The Borrower will pay all amounts
         due to the Lender under the Loan Documents in accordance with the terms
         thereof and will observe,


                                      26
<PAGE>

         perform and comply with every covenant, term and condition expressed
         or implied in the Loan Documents.

                  (b) PREFERENTIAL RIGHT TO PURCHASE HYDROCARBONS. The Borrower
         will enter into and perform the Hydrocarbon Purchase and Sale Agreement
         in the form of the Base Agreement for Natural Gas Purchase Transactions
         and will, upon the written request of the Lender, enter into and
         perform a similar document (on terms reasonably acceptable to the
         Borrower) with the Lender or such Affiliate of the Lender as the Lender
         may designate. For the avoidance of doubt, the Borrower agrees that
         prices based on the parameters set forth in SCHEDULE 7.1(f)(i) shall be
         deemed reasonable for purposes of any agreement for the purchase and
         sale of oil.

                  (c) COMPLIANCE WITH TAX LAWS. The Borrower shall comply with
         all federal, state or local laws and regulations regarding the
         collection, payment and deposit of employee' income, employment, and
         social security and sales and use taxes and taxes related to royalty
         payments.

                  (d) BOOKS, FINANCIAL STATEMENTS AND REPORTS. The Borrower will
         at all times maintain full and accurate books of account and records
         and a standard system of accounting and will furnish the following
         statements and reports to the Lender at the Borrower's expense:

                           (i) As soon as available, and in any event within one
                  hundred twenty (120) days after the end of each Fiscal Year,
                  complete audited consolidated and consolidating financial
                  statements of the Parent and the Borrower, prepared in
                  reasonable detail in accordance with GAAP. These financial
                  statements shall contain a balance sheet as of the end of such
                  Fiscal Year and statements of earnings, of cash flows, and of
                  changes in the capital accounts for such Fiscal Year, each
                  setting forth in comparative form the corresponding figures
                  for the preceding Fiscal Year. The auditors shall be
                  independent certified public accountants acceptable to the
                  Lender in its reasonable discretion, provided that the
                  accountants that audited the Fiscal Year 1998 financial
                  statements of the Parent and the Borrower are deemed
                  acceptable to the Lender.

                           (ii) As soon as available, and in any event within
                  sixty (60) days after the end of each Fiscal Quarter, the
                  Parent and the Borrower's consolidated and consolidating
                  balance sheet as of the end of such Fiscal Quarter and
                  statements of the Borrower's earnings and cash flows for the
                  period from the beginning of the then current Fiscal Year to
                  the end of such Fiscal Quarter, all in reasonable detail and
                  prepared in accordance with GAAP, subject to changes resulting
                  from normal year-end adjustments.

                           (iii) As and when furnished, copies of all reports
                  and other information provided by any Person (other than the
                  Lender) to the Parent or the Borrower in connection with the
                  Loan Documents, except such as are subject to attorney-client
                  privilege, attorney work product privilege or any other
                  privilege. The Borrower


                                      27
<PAGE>

                  may arrange for such reports and information to be provided
                  directly to the Lender by the Person providing the same to
                  the Parent and the Borrower.

                  (e) OTHER INFORMATION AND INSPECTIONS. The Borrower will
         furnish to the Lender any information which the Lender may from time to
         time reasonably request in writing concerning any covenant, provision
         or condition of the Loan Documents or any matter in connection with the
         Parent or the Borrower's assets, business and/or operations (other than
         geological, geophysical and other technical data relating to assets
         other than the Properties). The Borrower will (and will cause the
         Parent to) permit representatives appointed by the Lender (including
         independent accountants, agents, attorneys, appraisers and any other
         Persons), at the risk and expense of the Lender or such
         representatives, to visit and inspect, during reasonable business hours
         and upon reasonable prior written notice, its books of account and
         other books and records relating to the Properties and other
         Collateral, and any facilities or other business assets relating to the
         Collateral, and to make photocopies and/or photographs thereof, and to
         write down and record any information such representatives obtain, and
         the Borrower shall (and will cause the Parent to) permit the Lender or
         its representatives to investigate and verify the accuracy of the
         information furnished to the Lender in connection with the Loan
         Documents and to discuss all such matters with its officers, employees
         and representatives. In addition, the Borrower will (and will cause the
         Parent to) permit any such representatives appointed by the Lender, at
         the risk and expense of the Lender or such representatives, to visit
         and inspect, during reasonable hours and upon similar advance written
         notice, the Properties and other Collateral. The Lender agrees that it
         will take all reasonable steps to keep confidential any proprietary
         information given to it by the Borrower and the Parent; provided,
         however, that this restriction shall not apply to information which (i)
         is at the time in question publicly available, (ii) is required to be
         disclosed by law or by any order, rule or regulation (whether valid or
         invalid) of any court or governmental agency, or authority, (iii) is
         disclosed to the Lender's Affiliates, auditors, attorneys, lenders or
         agents, or (iv) is disclosed in the course of the defense or
         enforcement of the Loan Documents or the defense or enforcement of the
         Lender's exercise of its rights thereunder, provided that, with respect
         to information furnished to Persons identified in clause (iii) (except
         when furnished pursuant to clause (iv)), such Person shall be subject
         to the foregoing confidentiality obligations applicable to the Lender.
         Nothing in this SECTION 7.1(e) shall be construed to require (i) the
         Borrower (or the Parent) to deliver to the Lender any data, records, or
         other information in violation of confidentiality agreements or other
         restrictions against disclosure or transfer under agreements between
         the Borrower and any third person, (ii) such delivery in the absence of
         compliance by the Lender with the conditions to such disclosure or
         transfer under such agreements, or (iii) the Borrower (or the Parent)
         to pay any licensing fee due in connection with any such disclosure or
         transfer, all such licensing fees being for the account of the Lender
         to the extent disclosed in writing to the Lender prior to such
         disclosure or transfer.

                  (f) RESERVE REPORTS. On or before each March 30 after the
         Closing Date until the Loan Termination Date, the Borrower shall cause
         the preparation and delivery to the Lender of petroleum engineering
         reports, in a form satisfactory to the Lender, relating to the
         Properties and prepared as of the preceding December 31 (collectively,
         the "RESERVE REPORTS" and individually, a "RESERVE REPORT"). The Lender
         may request one additional


                                      28
<PAGE>

         Reserve Report per calendar year. Each annual Reserve Report
         required hereby shall be prepared by Engineers and shall be prepared
         at the Borrower's sole expense. Any additional Reserve Reports shall
         be prepared by Engineers but at the expense of the requesting party.
         Each Reserve Report shall set forth updated estimates of proved
         developed producing reserves, proved developed non-producing
         reserves, proved undeveloped reserves, projected production profiles
         and overall economics of the Properties. Each Reserve Report will be
         based on the following assumptions:

                           (i) Hydrocarbon pricing used will be determined by
                  the Lender using the parameters set forth on SCHEDULE
                  7.1(f)(i).

                           (ii) Average lease operating expenses and production
                  taxes will be derived by the Engineers who prepare such report
                  from the Operator's best estimate and historical operating
                  expenses.

                  (g) NOTICE OF INVESTIGATIONS OR PROCEEDINGS. The Borrower
         shall give the Lender prompt written notice of any proceeding at law or
         in equity against the Borrower, or any investigation or proceeding
         before or by any administrative or governmental agency relating to the
         Borrower or any of the Collateral if, in any case, such could
         reasonably be expected to have an Adverse Effect.

                  (h) NOTICE OF DAMAGE TO COLLATERAL. The Borrower shall give
         the Lender prompt written notice of any destruction or substantial
         damage to any material portion of the Collateral and of the occurrence
         of any condition or event which has caused, or may cause, material loss
         or depreciation in the value of any property subject to the Lender's
         Liens or the Mortgage.

                  (i) MAINTENANCE OF LICENSES. The Borrower shall maintain all
         licenses, permits, charters and registrations which are required for
         the conduct of its business and where the failure to have such could
         reasonably be expected to have an Adverse Effect.

                  (j) MAINTENANCE OF RIGHTS; DEFENSE OF PRIORITY. The Borrower
         will maintain, preserve, protect and keep all of its contractual and
         property rights with respect to the Collateral, other than those
         released to the Lender in connection with the Loan Documents, and will
         not waive, amend or release any such rights, except when to do so could
         not reasonably be expected to have an Adverse Effect. Notwithstanding
         the fact that the liens, claims and encumbrances described in the Debt
         Restructure Agreement are Permitted Encumbrances, if any Participating
         Creditor asserts a lien, claim or encumbrance with respect to the
         Collateral that purports to have priority over the claims or Liens
         granted pursuant to the Loan Documents, then the Borrower will take all
         necessary action to defend in good faith, at the Borrower's sole cost,
         the priority of the claims of Lender and Lender's Affiliates granted
         pursuant to the Loan Documents.

                  (k) MAINTENANCE OF EXISTENCE AND QUALIFICATIONS. The Borrower
         will maintain and preserve its corporate existence and its rights and
         franchises in full force and effect and will qualify and/or remain
         qualified to do business as a foreign corporation in all


                                      29
<PAGE>

         states or jurisdictions where required by applicable law and the
         failure to do so could reasonably be expected to have an Adverse
         Effect.

                  (l) PAYMENT OF TAXES AND TRADE DEBT. The Borrower will (i)
         make all payments to the Participating Creditors required under Section
         8.01 of the Debt Restructure Agreement on or before the earlier of the
         fifteenth day after the Closing Date and the day by which such payments
         are required to have been made under the Debt Restructure Agreement;
         (ii) make all payments of Convenience Claims (as defined in the Debt
         Restructure Agreement) on or before the forty-fifth day after the
         Closing Date; and (iii) timely pay all other sums coming due under the
         Debt Restructure Agreement. Except to the extent being contested in
         good faith, the Borrower will (x) timely pay all taxes, assessments and
         other governmental charges or levies imposed upon it or upon its
         income, profits or property; (y) within thirty (30) days after the same
         becomes due (or, with respect to a particular vendor, such longer
         period that is acceptable to such vendor) pay all Debt (other than the
         Obligations) owed by it. The Borrower will maintain appropriate
         accruals and reserves for all of the foregoing Debt in accordance with
         GAAP.

                  (m) CREDITORS. In addition to the matters disclosed in the
         Debt Restructure Agreement, the Borrower shall notify the Lender
         promptly if the Borrower fails to make any payment to lessors,
         suppliers, vendors, owners of royalty interest, tax authorities or
         other Persons, where such nonpayment could reasonably be expected to
         result in any Lien, other than a Permitted Encumbrance, against any
         item of Collateral or otherwise have an Adverse Effect. At any time
         such notification is due, the Borrower shall also provide the Lender
         with a statement showing the identity of such creditors, the amount due
         to each and the date each payment was due.

                  (n) INTEREST. The Borrower hereby promises to pay interest to
         the Lender pursuant to the terms and at the rate stated in each Note on
         all Obligations that relate to such Note (including Obligations to pay
         fees or to reimburse or indemnify the Lender) after such Obligations
         become due. The Borrower further agrees that (i) any interest which has
         accrued on the Advancing Note and is not paid when due shall be added
         to and become part of the Loans and (ii) any interest which has accrued
         on the EnCap Junior Note and is not paid when due shall be added to the
         principal balance thereof.

                  (o) COMPLIANCE WITH AGREEMENTS AND LAW. The Borrower will
         perform all material obligations it is required to perform under the
         terms of the Loan Documents. The Borrower will conduct its business and
         affairs in compliance with all laws, regulations and orders applicable
         thereto, including Environmental Laws, except where the failure to do
         so would not have an Adverse Effect.

                  (p) INSURANCE. The Borrower shall keep, or cause to be kept,
         all of the Mortgaged Properties (as that term is defined in the
         Mortgages) that are fixtures or personal property insured by insurance
         companies having a rating no lower than AAA by A.M. Best Company or
         otherwise acceptable to the Lender against loss or damage by fire or
         other risk usually insured against by owners or users of similar
         properties in similar businesses under extended coverage endorsement

                  (s) ENVIRONMENTAL AND OTHER LAWS. Except as disclosed in
         SCHEDULE 7.1(s) and except where non-compliance would not reasonably be

         business in compliance with all applicable federal, state or local

         determining and minimizing the tax liability, if any, of the Lender to

         cooperate with the reasonable requests of the Lender for purpose of
         preparing any return with respect to any such tax liability.

         $50,000 in the aggregate for legal, title, environmental and other due
         diligence expenses incurred by the Lender, and, thereafter, will
         reimburse the Lender for all reasonable legal expenses incurred in
         connection with any subsequent amendment, mortgage, extension or

         the terms thereof. Notwithstanding anything to the contrary in this
         Agreement or in any other Loan Document, the undertakings of the
         Borrower in this SECTION 7.1(cc) shall be and are full recourse
         obligations of the Borrower.

                  (dd) OPERATING REPORTS; QUARTERLY MEETINGS. Within thirty (30)

         with a rolling revenue, lease operating expense and capital
         expenditure forecast by month covering the Borrower's interest in
         the Properties for the succeeding twelve (12) month period (each
         such forecast, an "OPERATING REPORT"). Such Operating Reports shall
         include a brief discussion by the Borrower of operating and
         financial variances from the prior Operating Report delivered to the
         Lender. On or before the tenth Business Day of each calendar quarter
         the Borrower shall make available responsible management to discuss

         the Lender.

         Section 7.2 NEGATIVE COVENANTS. The Borrower warrants, covenants and

         to the extent pursuant to or as expressly allowed under this Agreement
         and the Security Documents encumbering such Collateral;

                  (c) COMPENSATION. The Borrower shall not, directly or
         indirectly, enter into any employment agreement or other arrangement
         with or for the benefit of an officer, director or employee of the
         Borrower other than for reasonable compensation for services as an
         officer, director or employee;

                  (d) LIMITATION ON CREDIT EXTENSIONS. Neither the Borrower nor
         any of its Affiliates will extend credit, make advances or make loans
         to any Person other than in the ordinary course of business; provided,
         however, that amounts outstanding on the Starbucks Note Receivable on
         the Closing Date may remain outstanding but no additional sums may be
         advanced thereunder.

                  (e) CERTAIN CONTRACTS; AMENDMENTS. The Borrower shall not
         amend or permit any amendment to any contract or lease with respect to

         the ordinary course of the Borrower's business, the Grabois Note, the

         Borrower shall not assume, guaranty, or endorse or otherwise become
         directly or contingently liable in connection with any other liability
         of any other Person other than majority owned Affiliates, except for
         the indemnification contained herein; provided, however, that the
         foregoing shall not prohibit the endorsement of negotiable instruments
         for deposit or collection or incurrence of obligations under operating
         agreements and similar transactions in the ordinary course of business.
         For the purposes hereof, "guaranty" shall include any agreement,

         lessor, property or services in any such case primarily for the purpose
         of enabling another Person to make payment of any such debt or
         liability, or to make any payment (whether as a capital contribution,
         purchase of any equity interest or otherwise) to assure a minimum
         equity, asset base, working capital or other balance sheet or financial
         condition, in connection with Debt or liability of another Person, or
         to supply funds to or in any manner invest in another Person in
         connection with such Person's Debt or liability;

         of a total of $50,000 during the term of the Loans, except for
         reasonable consideration and in the ordinary course of its business;

                  (i) DEFAULTS. Except as previously disclosed to the Lender,
         the Borrower shall not cause a default under any lease, mortgage, deed
         of trust or lien with respect to the Properties;

         right to contest in good faith or cure within thirty (30) days of the
         filing of any Lien, and except as provided in the Debt Restructure
         Agreement, the Borrower shall not suffer to exist any valid Lien
         against the Properties or consent to the filing of any financing
         statements on any of the Collateral, other than the Liens created by
         the Security Documents and other Permitted Encumbrances;

                  (k) LIMITATION ON FUNDAMENTAL CHANGES. The Borrower will not
         enter into any merger, consolidation or amalgamation, or liquidate,
         wind up or dissolve itself (or suffer any liquidation or dissolution),
         or make any material change in its present method or conducting
         business;

                  (l) LIMITATION ON LOCATION CHANGES. The Borrower shall not
         transfer its principal office or its registered offices outside of the

         at which the same are presently kept in accordance with SECTION 6.1
         without prior written notice to the Lender and the execution and
         delivery to the Lender of such additional Security Documents as may be
         reasonably required by the Lender in connection therewith; and

                  (m) AFFILIATE TRANSACTIONS. The Borrower shall not sell or
         transfer any property or assets to, or purchase or acquire any property
         or assets from, or otherwise engage in any


                                      35
<PAGE>

         transactions with any of its Affiliates except in the ordinary
         course of business and on terms no less favorable to the Borrower
         than could be obtained on an arm's length basis from unrelated third
         parties.

                ARTICLE 8: FURTHER RIGHTS OF LENDER AND BORROWER

         Section 8.1 MAINTENANCE OF SECURITY INTERESTS. Until the Obligations
are repaid in full, the Borrower, at its own expense, shall do all things
reasonably requested by the Lender in writing and shall deliver all instruments
reasonably requested by the Lender in writing to protect or perfect any security
interest, mortgage or lien given hereunder or under any Security Documents,
including, without limitation, financing statements under the Uniform Commercial
Code. The Borrower hereby authorizes the Lender, during the continuance of any
Event of Default, to appoint such Person or Persons as the Lender may designate
as its attorney-in-fact to endorse the name of the Borrower on any checks,
notes, drafts or other forms of payment or security that may rightfully come
into the possession of either the Lender or any Affiliate of the Lender, to sign
the Borrower's name on invoices or bills of lading, drafts against customers,
notices of assignment, verifications and schedules that relate exclusively to
the Collateral and, generally, to do all things reasonably necessary to carry
out this Agreement and the Security Documents to the extent required of the
Borrower pursuant to this SECTION 8.1 and SECTION 11.10. The powers granted
herein, being coupled with an interest, are irrevocable so long as any
Obligations are outstanding. Neither the Lender nor its attorney-in-fact shall
be liable for any act or omission, error in judgment or mistake of law so long
as the same is not the result of a malicious act, willful misconduct, or gross
negligence of the Lender or its attorney-in-fact. Upon payment and performance
of all Obligations of the Borrower to the Lender, such power of attorney will
become null and void, and, upon request by the Borrower, the Lender or any
Noteholder will provide an instrument in recordable form that terminates such
procuration.

         Section 8.2 PERFORMANCE OF OBLIGATIONS. In the event that the Borrower
fails to purchase or maintain insurance in accordance with the requirements of
this Agreement, or to pay any tax, assessment, government charge or levy, except
as the same may be otherwise permitted hereunder, or in the event that any Lien
prohibited hereby shall not be paid in full or discharged, or in the event that
the Borrower shall fail to perform or comply with any other covenant, promise or
Obligation to the Lender hereunder or under any Loan Document, which failure may
reasonably be expected to cause an Adverse Effect, the Lender may, following
written notice to the Borrower affording the Borrower ten (10) days after the
date of such notice to cure the relevant circumstance, but shall not be required
to, perform, pay, satisfy, discharge or bond the same for the account of the
Borrower, and all monies so paid by the Lender, including, without limitation,
reasonable attorneys' fees and disbursements, shall, at the Lender's option,
either be treated as an additional Obligation of the Borrower to the Lender
hereunder and under the other Loan Documents, or be treated as a debit to the
Borrower Sub-Account in accordance with SECTION 2.7(a). If the Lender has
attempted to send the notice required hereby but, as the result of inadvertence
not constituting gross negligence or willful misconduct, such notice is
improperly addressed or is not timely delivered, the failure of the Borrower to
have timely received such notice shall not in any way prohibit or otherwise
limit the exercise by the Lender of its rights under this Section.


                                      36
<PAGE>

         Section 8.3 OVERRIDING ROYALTY INTEREST. At Closing, the Borrower shall
assign the Overriding Royalty Interest to the Lender by executing, and
delivering to the Lender, the Overriding Royalty Interest Conveyance.

         Section 8.4 ORRI OPTION. Pursuant to the terms of the Overriding
Royalty Interest Conveyance, the Borrower shall have an option to repurchase the
Overriding Royalty Interest after the Closing Date at a price (the "PURCHASE
PRICE") to be determined by a Reserve Report that incorporates, without
limitation, forward pricing determined by the Engineers pursuant to the
parameters set forth on SCHEDULE 7.1(f)(i), historical operating expenses
verified by the Engineers and proven reserves attributable to the Overriding
Royalty Interest that is prepared by Engineers, such as Ryder Scott, Netherland
Sewell or the Engineers that prepared the Reserve Report most recently delivered
hereunder, using a ten percent (10%) discount rate; provided, however, that the
ORRI Option is a non-assignable option granted by the Lender solely to the
Borrower and, notwithstanding any right that may be granted to the Borrower in
the Overriding Royalty Interest Conveyance to assign, sell, transfer or
otherwise convey any of the Properties, the exercise of the ORRI Option shall be
solely by the Borrower and shall be with relation to the entire Overriding
Royalty Interest as granted in the Overriding Royalty Interest Conveyance.
Furthermore, any notice to the Borrower hereunder shall be deemed as actual
notice to its assignees of the Properties ("ASSIGNEES"), if any. The Borrower
may exercise its option by sending written notice of such exercise to the Lender
specifying an effective date for the determination of the Purchase Price that is
the first day of the month preceding the month in which the notice is delivered
to the Lender ("ORRI SALE DATE"), accompanied by the Reserve Report that
establishes the Purchase Price, and stating that the Borrower is ready, willing
and able to close such purchase and pay the Purchase Price within thirty (30)
days from the date of the notice, without any conditions with respect to
obtaining financing, or otherwise. If the Purchase Price established in the
Reserve Report was appropriately determined based on the parameters set forth in
SCHEDULE 7.1(f)(i), then the parties shall proceed to close such purchase and
sale transaction within thirty (30) days from the Lender's receipt of the
Borrower's option exercise notice. At the closing, the Borrower shall pay the
Purchase Price to the Lender in cash or by wire transfer to an account
designated by the Lender, and the Lender shall assign the Overriding Royalty
Interest to the Borrower by recordable form of assignment with a special
warranty of title by, through or under the Lender, but not otherwise. The
Purchase Price shall be adjusted downward by the amount of any net revenues
received by the Lender prior to the closing for production attributable to the
Overriding Royalty Interest subsequent to the ORRI Sale Date, and shall be
adjusted upward for any revenues that have accrued with respect to the
Overriding Royalty Interest for production prior to the ORRI Sale Date, that
have not yet been paid to the Lender. After the closing, any revenues received
by the Lender that are attributable to the Overriding Royalty Interest shall be
promptly remitted to the Borrower. If the Lender does not agree with the
Purchase Price proposed by the Borrower in the option exercise notice, it shall
notify the Borrower promptly and in any event within ten (10) days after the
receipt of such notice, and the parties shall endeavor to reach agreement on the
Purchase Price within thirty (30) days thereafter. If they are able to do so,
closing, as provided above, shall occur within ten (10) days after they have
reached agreement on the Purchase Price. If they are unable to reach agreement
on the Purchase Price, either party may elect to have the Purchase Price
determined through arbitration in accordance with ARTICLE 12 hereof, and the
closing shall then occur within ten (10) days after the arbitrator(s) have
notified the Lender and the Borrower of the Purchase Price that has been so
determined. After the Borrower has notified the Lender of the Borrower's

election to exercise its option to purchase the Overriding Royalty Interest,
such election shall not be revocable, and the Lender shall have the right to
enforce specific performance of the Borrower's resulting obligation to purchase,
so long as the Lender can deliver title to the Overriding Royalty Interest to
the Borrower without being in violation of its special warranty of title.

         Section 8.5 NON-RECOURSE. It is expressly understood and agreed that,
except as set forth in SECTION 7.1(cc), the undertaking of the Borrower to pay
any indebtedness or perform any obligation under the Loan Documents is included
herein for the sole purpose of establishing the continuing existence of the debt
and the maturity of such debt. Except as set forth in SECTION 7.1(cc), and
notwithstanding anything else in the Loan Documents to the contrary, including,
but not limited to, this Agreement and any certificate, opinion, or documents of
any nature whatsoever, neither the Lender nor its successors or assigns, nor any
Noteholder, nor any other holder or holders of the indebtedness will have any
claim, remedy, or right to proceed against the Borrower for the payment of any
deficiency or any other sum or performance of any obligation of any nature
whatsoever under the Loan Documents from any source other than the Collateral,
for the payment of such indebtedness or the satisfaction of such liability or
for the satisfaction of any obligation by the Borrower to the Lender, whether
sounding in contract, tort or otherwise; provided, however, that nothing
contained herein will limit, restrict, or impair the rights of the holders of
the debt: (i) to accelerate the maturity of the debt during the continuance of
an Event of Default, to bring suit and obtain a judgment against the Borrower on
the debt for purposes of enforcement of any Security Document, provided that the
satisfaction of such judgment is limited solely to the Collateral, and the
exercise of all of the Lender's rights and remedies to foreclose or otherwise
realize upon the Collateral, including rights to collect sums due or to become
due under the Collateral; or (ii) in the event of fraud or misapplication of
funds on the part of the Borrower.

         Section 8.6 REMOVAL AND APPOINTMENT OF OPERATOR. Subject to the terms
of operating agreements affecting the Properties, the Lender shall, in its
reasonable discretion, have the right to approve or disapprove any action taken
by the Borrower to appoint, remove or replace the Operator of any of the
Properties. The Borrower shall not directly or indirectly modify or amend
(including, without limitation, by waiver of any term thereof) any Operating
Agreement, or appoint, remove or replace any Operator, without the prior written
consent of the Lender.

         Section 8.7 SET-OFF RIGHTS. Upon the occurrence and during the
continuance of an Event of Default, the Lender shall have the right to set-off
and apply against the Obligations in such manner as the Lender may determine,
upon written notice at any time to the Borrower, any and all deposits (general
or special, time or demand, provisional or final) or other sums at any time
credited by or owing from the Lender or any depositary to the Borrower whether
or not the Obligations are then due, except there shall not be such right
against any amounts owing to third-party working interest and royalty interest
holders of which the Lender shall have been notified. The Lender shall provide
notice to the Borrower not later than five (5) days following any application of
such funds.

         conditions to the obligations of the Parent, the Borrower, the
         Participating Creditors or the Collateral Agent under the Debt
         Restructure Agreement have been satisfied; or

                  (v)      the Borrower shall not have (i) paid in full the
         indebtedness identified on Schedule 2 and (ii) obtained the release of
         any Liens filed of record in respect thereof on or before December 31,
         1999.

         Section 10.2 ACCELERATION.

                  (a) AUTOMATIC ACCELERATION. Upon the occurrence of an Event of
         Default described in SUBSECTION (j)(i), (j)(ii) or (j)(iii) of SECTION
         10.1, all of the Obligations shall thereupon be immediately due and
         payable, without demand, presentment, notice of demand or of dishonor
         and nonpayment, protest, notice of protest, notice of intention to
         accelerate, declaration or notice of acceleration, or any other notice
         or declaration of any kind, all of which are hereby expressly waived by
         the Borrower and each obligor who at any time ratifies or approves this
         Agreement. After any acceleration under this subsection, any obligation
         of the Lender to make any further Loans or advances of any kind under
         any Loan Document shall at the option of the Lender be permanently
         terminated.

                  (b) PARTIAL ACCELERATION. Upon the occurrence and during the
         continuance of any Event of Default described in SUBSECTION (a), (c),
         (d) or (e) of SECTION 10.1 with respect to any Obligation owing or Loan
         Document executed in connection therewith, the Lender at any time and
         from time to time may declare any and all such Obligations immediately
         due and payable, without demand, presentment, notice of demand or of
         dishonor and nonpayment, protest, notice of protest, notice of
         intention to accelerate, declaration or notice of acceleration, or any
         other notice or declaration of any kind, all of which are hereby
         expressly waived by the Borrower. Upon the Lender's acceleration of any
         or all of the Obligations, it shall use commercially reasonable efforts
         to give the Borrower reasonably contemporaneous written notice thereof,
         but any inadvertent error in the timing or manner of giving such notice
         shall not affect, in any way, the otherwise proper acceleration under
         the terms of this Agreement of such Obligations.

                  (c) TAX CLAIMS. Upon the occurrence and during the continuance
         of an Event of Default described in SUBSECTION (g) of SECTION 10.1, the
         Lender may at any time and from time to time and without notice to the
         Borrower, except as may otherwise be required hereunder, declare any or
         all of the Obligations associated with such Tax Claim (or which the
         Lender in its reasonable discretion believes will be likely to become
         associated with such Tax Claim or any similar future Tax Claim)
         immediately due and payable, and all such Obligations shall thereupon
         be immediately due and payable, without demand, presentment, notice of
         demand or of dishonor and nonpayment, protest, notice of protest,
         notice of intention to accelerate, declaration or notice of
         acceleration, or any other notice or declaration of any kind, all of
         which are hereby expressly waived by the Borrower. Upon the Lender's
         acceleration of any or all of the Obligations, it shall use
         commercially

                                       47
<PAGE>

         reasonable efforts to give the Borrower reasonably contemporaneous
         written notice thereof, but any inadvertent error in the timing or
         manner of giving such notice shall not affect, in any way, the+
         otherwise proper acceleration under the terms of this Agreement of
         such Obligations.

                  (d) OTHER ACCELERATION. Upon the occurrence and during the
         continuance of any Event of Default not described in the preceding
         SUBSECTIONS (a), (b) or (c) of this SECTION 10.2, the Lender may at any
         time and from time to time and without notice to the Borrower, except
         as may otherwise be required hereunder, declare any or all of the
         Obligations immediately due and payable, and all such Obligations shall
         thereupon be immediately due and payable, without demand, presentment,
         notice of demand or of dishonor and nonpayment, protest, notice of
         protest, notice of intention to accelerate, declaration or notice of
         acceleration, or any other notice or declaration of any kind, all of
         which are hereby expressly waived by the Borrower. Upon the Lender's
         acceleration of any or all of the Obligations, it shall use
         commercially reasonable efforts to give the Borrower reasonably
         contemporaneous written notice thereof, but any inadvertent error in
         the timing or manner of giving such notice shall not affect, in any
         way, the otherwise proper acceleration under the terms of this
         Agreement of such Obligations.

         Section 10.3 REMEDIES. If any Event of Default shall occur and be
continuing, the Lender's obligation to make any Development Loans shall be
suspended, except as expressly provided to the contrary herein, and the
Lender may protect and enforce its rights under the Loan Documents by any
appropriate proceedings, including proceedings for specific performance of
any covenant or agreement contained in any Loan Document, and the Lender may
enforce the payment of any Obligations due or enforce any other legal or
equitable right. All rights, remedies and powers conferred upon the Lender
under the Loan Documents shall be deemed cumulative and not exclusive of any
other rights, remedies or powers available under the Loan Documents or at law
or in equity. Notwithstanding the foregoing, the payment of the Obligations
of the Borrower shall be made solely from the cash flows from the Collateral,
or in the Event of Default by the Borrower, from any amounts derived from the
exercise by the Lender of its rights hereunder, or under any other Loan
Document, with regard to the Collateral including proceeds of foreclosure;
but without recourse by the Lender to any of the cash flows, properties or
other assets of the Borrower not included in or derived from the Collateral.
If any Unmatured Event of Default shall occur and be continuing, the Lender's
obligation to make any Development Loans shall be suspended, except as
expressly provided to the contrary herein, so long as any such Unmatured
Events of Default or resulting Event of Default is continuing.

         Section 10.4 INDEMNITY. Except to the extent expressly provided
otherwise in another Loan Document, the Borrower agrees to indemnify the
Lender, upon written demand, from and against any and all liabilities,
obligations, claims, losses, damages, penalties, fines, actions, judgments,
suits, settlements, costs, expenses or disbursements (including reasonable
fees of attorneys, experts and advisors) of any kind or nature whatsoever (in
this section collectively called "liabilities and costs") which to any extent
(in whole or in part) may be imposed on, incurred by or asserted against the
Lender growing out of, resulting from or in any other way associated with any
of the Collateral, the Loan Documents or the transactions and events
including the enforcement or defense thereof at any time associated therewith
or contemplated therein (including any violation or noncompliance with any
Environmental Laws by any Person

                                       48
<PAGE>

or any liabilities or duties of any Person with respect to Hazardous
Materials found in or released into the environment). THE FOREGOING
INDEMNIFICATION SHALL APPLY WHETHER SUCH LIABILITIES AND COSTS ARE IN ANY WAY
OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR
OMISSION OF ANY KIND BY THE LENDER; PROVIDED, HOWEVER, THAT, UNDER THIS
SECTION, NO PERSON SHALL BE ENTITLED TO RECEIVE INDEMNIFICATION FOR THAT
PORTION, IF ANY, OF ANY LIABILITIES AND COSTS WHICH IS CAUSED BY SUCH
PERSON'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. As used in this section the
term "Lender" shall refer not only to the Person designated as such in
Section 1.1, but also to its lender(s) and shareholders and, with respect to
each of the foregoing, each director, officer, agent, attorney, employee,
representative and Affiliate of such Person.


                           ARTICLE 11: MISCELLANEOUS

                  (a) WAIVERS AND AMENDMENTS. No failure or delay (whether by
         course of conduct or otherwise) by the Lender in exercising any right,
         power or remedy which the Lender may have under any of the Loan
         Documents shall operate as a waiver thereof or of any other right,
         power or remedy, nor shall any single or partial exercise by the Lender
         of any such right, power or remedy preclude any other or further
         exercise thereof or of any other right, power or remedy. No waiver of
         any provision of any Loan Document and no consent to any departure
         therefrom shall ever be effective unless it is in writing and signed by
         the Lender, and then such waiver or consent shall be effective only in
         the specific instances and for the purposes for which given and to the
         extent specified in such writing. No notice to or demand on the
         Borrower shall in any case of itself entitle the Borrower to any other
         or further notice or demand in similar or other circumstances. This
         Agreement and the other Loan Documents set forth the entire
         understanding and agreement of the parties hereto and thereto with
         respect to the transactions contemplated herein and therein and
         supersede all prior discussions and understandings with respect to the
         subject matter hereof and thereof, and no modification or amendment of
         or supplement to this Agreement or the other Loan Documents shall be
         valid or effective unless the same is in writing and signed by the
         party against whom it is sought to be enforced.

                  (b) ACKNOWLEDGMENTS AND ADMISSIONS. The Borrower hereby
         represents, warrants and acknowledges that (i) it has been advised by
         counsel in the negotiation, execution and delivery of the Loan
         Documents to which it is a party, (ii) it has made independent
         decisions to enter into this Agreement and the other Loan Documents to
         which it is a party, without reliance on any representation, warranty,
         covenant or undertaking by the Lender, whether written, oral or
         implicit, other than as expressly set out in this Agreement or in
         another Loan Document delivered on or after the date hereof, (iii)
         there are no representations, warranties, covenants, undertakings or
         agreements by the Lender to the Borrower as to the Loan Documents
         except as expressly set out in this Agreement or in another Loan
         Document delivered on or after the date hereof, (iv) the Lender owes no
         fiduciary duty to the Borrower with respect to any Loan Document or the

                                       49
<PAGE>

         transactions contemplated thereby, (v) the relationship pursuant to the
         Loan Documents between the Borrower, on one hand, and the Lender, on
         the other hand, is and shall be solely that of debtor and creditor,
         respectively, (vi) no partnership or joint venture exists with respect
         to the Loan Documents between the Borrower and the Lender, (vii) should
         an Event of Default or Unmatured Event of Default occur or exist the
         Lender will determine in its sole discretion and for its own reasons
         what remedies and actions it will or will not exercise or take at that
         time, (viii) without limiting any of the foregoing, the Borrower is not
         relying upon any representation or covenant by the Lender, or any
         representative thereof, and no such representation or covenant has been
         made, that the Lender will, at the time of an Event of Default or
         Unmatured Event of Default, or at any other time, waive, negotiate,
         discuss or take or refrain from taking any action permitted under the
         Loan Documents with respect to any such Event of Default or Unmatured
         Event of Default or any other provision of the Loan Documents, and (ix)
         the Lender has relied upon the truthfulness of the acknowledgments in
         this section in deciding to execute and deliver this Agreement and to
         make the Loans.

THIS WRITTEN AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL
AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

         Section 11.2 SURVIVAL OF AGREEMENTS: CUMULATIVE NATURE. The Lender
may assign and/or transfer its rights and privileges under the Loan Documents
at any time and from time to time; provided that the Lender shall remain
liable to perform, or cause to be performed, its obligations to the Borrower
under the terms of the Loan Documents. All of the various representations,
warranties, covenants and agreements of the Borrower in the Loan Documents
shall survive the execution and delivery of this Agreement and the other Loan
Documents and the performance hereof and thereof, including the making or
granting of the Loans and the delivery of the Notes and the other Loan
Documents, and shall further survive until all of the Obligations are paid in
full to the Lender and all of the Lender's obligations to the Borrower are
terminated. The representations, warranties and covenants made by the
Borrower in the Loan Documents, and the rights, powers and privileges granted
to the Lender in the Loan Documents, are cumulative, and, except for
expressly specified waivers and consents, no Loan Document shall be construed
in the context of another to diminish, nullify or otherwise reduce the
benefit to the Lender of any such representation, warranty, covenant, right,
power or privilege. In particular and without limitation, no exception set
out in this Agreement to any representation, warranty or covenant herein
contained shall apply to any similar representation, warranty or covenant
contained in any other Loan Document, and each such similar representation,
warranty or covenant shall be subject only to those exceptions which are
expressly made applicable to it by the terms of the various Loan Documents.

         Section 11.3 NOTICES. All notices, requests, consents, demands and
other communications required or permitted under any Loan Document shall be

and agreements contained in the Loan Documents shall bind and inure to the
benefit of solely the parties thereto and their respective successors and
assigns; provided, however, that the Borrower shall not assign or transfer

or right under any doctrines or theories of intended or third-party

         Section 11.5 GOVERNING LAW; SUBMISSION TO PROCESS. EXCEPT TO THE
EXTENT THAT THE LAW OF ANOTHER JURISDICTION IS EXPRESSLY STIPULATED IN A LOAN
DOCUMENT OR MANDATORILY GOVERNS A LOAN DOCUMENT, THE LOAN DOCUMENTS SHALL BE
DEEMED CONTRACTS AND INSTRUMENTS MADE UNDER THE LAWS OF THE STATE OF TEXAS
AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH AND GOVERNED BY THE
LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.
THIS AGREEMENT HAS BEEN ENTERED INTO IN HOUSTON, TEXAS AND SHALL BE
PERFORMABLE FOR ALL PURPOSES IN HARRIS COUNTY, TEXAS. SUBJECT TO THE
PROVISIONS OF ARTICLE 12, COURTS WITHIN THE STATE OF TEXAS SHALL HAVE
JURISDICTION OVER ANY AND ALL DISPUTES BETWEEN THE BORROWER AND THE LENDER,
WHETHER IN LAW OR EQUITY, INCLUDING, BUT NOT LIMITED TO, ANY AND ALL DISPUTES
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT; AND
VENUE IN ANY SUCH DISPUTE WHETHER IN FEDERAL OR STATE COURT SHALL BE LAID IN
HARRIS COUNTY, TEXAS.

         Section 11.6 LIMITATION ON INTEREST. The Lender, the Borrower and
any other parties to any Loan Documents intend to contract in strict
compliance with applicable usury law from time to time in effect. In
furtherance thereof, the parties stipulate and agree that none of the terms
and provisions contained in the Loan Documents shall ever be construed to
create a contract to pay, for the use, forbearance or detention of money,
interest in excess of the maximum amount of interest permitted to be charged
by applicable law from time to time in effect. Neither the Borrower nor any
present or future guarantors, endorsers or other Persons hereafter becoming
liable for payment of any Obligation shall ever be liable for unearned
interest thereon or shall ever be required to pay interest thereon in excess
of the maximum amount that may be lawfully charged under applicable law from
time to time in effect, and the provisions of this section shall control over
all other provisions of the Loan Documents which may be in conflict or
apparent conflict herewith. The Lender expressly disavows any intention to
charge or collect excessive unearned interest or finance charges in the event
the maturity of any Obligation is accelerated. If (a) the maturity of any
Obligation is accelerated for any reason, (b) any Obligation is prepaid and
as a result any amounts held to constitute interest are determined to be in
excess of the legal maximum, or (c) the Lender or any other holder of any or
all of the Obligations shall otherwise collect moneys which are determined to
constitute interest which would otherwise increase the interest on any or all
of the Obligations to an amount in excess of that permitted to be charged by
applicable law then in effect, then all such sums determined to constitute
interest in excess of such legal limit shall, without penalty, be promptly
applied to reduce the then outstanding principal of the related Obligations
or, at the Lender's or such holder's option, promptly returned to the
Borrower or the other payor thereof upon such determination. In determining
whether or not the interest paid or payable under any specific circumstance
exceeds the maximum amount permitted under applicable law, the Lender and the
Borrower (and any other payors thereof) shall to the greatest extent
permitted under applicable law, (x) characterize any non-principal payment as
an expense, fee or premium rather than as interest, (y) exclude voluntary
prepayments and the effects thereof, and (z) amortize, prorate, allocate and
spread the total amount of interest throughout the entire contemplated term
of the instruments evidencing the Obligations in accordance with the amounts
outstanding from time to time thereunder and the maximum legal rate of
interest from time to time in effect under applicable law in order to
lawfully charge the maximum amount of interest permitted under applicable law.

         Section 11.7 TERMINATION; LIMITED SURVIVAL. In their sole and
absolute discretion, the Borrower and the Lender may each, at any time that
no Obligations are owing, elect in a notice

                                       52
<PAGE>

delivered to the other to terminate this Agreement; provided that prior to
the Drawdown Termination Date the Lender shall not, without the written
consent of the Borrower, be entitled to terminate its commitment to make
additional Development Loans. Upon receipt of such a notice, if no
Obligations are then owing, this Agreement and all other Loan Documents shall
thereupon be terminated and the parties thereto released from any prospective
obligations thereunder. Notwithstanding the foregoing or anything herein to
the contrary, any waivers or admissions made by the Borrower or the Lender in
any Loan Documents, and any obligations which any Person may have to
indemnify or compensate the Lender shall survive any termination of this
Agreement or any other Loan Document. At the request and expense of the
Borrower, the Lender shall prepare and execute all necessary instruments to
release and effect such termination of the Loan Documents; provided however,
that nothing in this SECTION 11.7 shall affect any and all continuing rights,
validity and enforceability of the Overriding Royalty Interest.

         Section 11.8 SEVERABILITY. If any term or provision of any Loan
Document shall be determined to be illegal or unenforceable, all other terms
and provisions of the Loan Documents shall nevertheless remain effective and
shall be enforced to the fullest extent permitted by applicable law.

         Section 11.9 COUNTERPARTS. This Agreement may be separately executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to constitute
one and the same Agreement.

         Section 11.10 FURTHER ASSURANCES. The parties agree (a) to furnish
upon written request to each other such information, (b) to execute and
deliver to each other such documents, and (c) to do such other acts and
things, all as the other party may reasonably request for the purpose of
carrying out the intent of this Agreement and the Loan Documents.

         Section 11.11 WAIVER OF PUNITIVE DAMAGES, ETC. THE BORROWER AND THE
LENDER HEREBY (a) IRREVOCABLY WAIVE, TO THE MAXIMUM EXTENT PERMITTED BY LAW
ANY RIGHT THEY MAY HAVE TO CLAIM OR RECOVER IN ANY ARBITRATION ANY SPECIAL,
EXEMPLARY, PUNITIVE, STATUTORY OR CONSEQUENTIAL DAMAGES OR DAMAGES OTHER
THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (b) CERTIFY THAT NO PARTY HERETO NOR
ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED,
EXPRESSLY OR OTHERWISE OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF
ARBITRATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (c) ACKNOWLEDGE THAT
EACH HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS
AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER
INDUCEMENTS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION.

         Section 11.12 REPRESENTATIONS AND WARRANTIES OF LENDER. To confirm
the Borrower's understanding concerning Lender and Lender's business and
obligations, and to induce the Borrower to enter into this Agreement and to
make the Loans, Lender represents and warrants to the Borrower that:

                                       53

<PAGE>

                  (a) ORGANIZATION AND GOOD STANDING. Lender is a corporation
         duly organized, validly existing and in good standing under the laws of
         Delaware, having all powers necessary to carry on its business and to
         enter into and consummate the transactions contemplated by the Loan
         Documents.

                  (b) AUTHORIZATION. Lender has taken all actions necessary to
         authorize the execution and delivery of the Loan Documents and to
         authorize the consummation of the transactions contemplated thereby and
         the performance of its obligations thereunder, subject to satisfaction
         of the terms and conditions of the Loan Documents. Lender is duly
         authorized to lend funds hereunder, subject to satisfaction of the
         terms and conditions of the Loan Documents.

                  (c) NO CONFLICTS OR CONSENTS. Except as expressly contemplated
         in the Loan Documents, no consent, approval, authorization or order of,
         and no notice to or filing with, any court or governmental authority or
         third-party is required in connection with the execution, delivery or
         performance by Lender of any Loan Document or to consummate any
         transaction contemplated by the Loan Documents.

                  (d) ENFORCEABLE OBLIGATIONS. This Agreement is, and the other
         Loan Documents when executed and delivered by Lender will be, legal,
         valid and binding obligations of Lender, enforceable in accordance with
         their terms except as such enforcement may be limited by bankruptcy,
         insolvency or similar laws of general application relating to the
         enforcement of debtor's rights or by principles of equity applicable to
         the enforcement of debtor's rights generally.

                  (e) COMPLIANCE WITH AGREEMENT AND LAW. The Lender will perform
         all material obligations it is required to perform under the terms of
         the Loan documents. Lender will conduct its business and affairs in
         material compliance with laws, regulations and orders applicable
         thereto.

         Section 11.13 IMI PROPERTY. The Lender has no obligation to fund any
advance in connection with the exploration or development of the IMI
Property. In the event that the Borrower requests the Lender to fund an
advance in connection with the exploration or development of the IMI Property
and the Lender does not elect to fund such advance, the Lender will, upon the
Borrower's written request and at the cost and expense of the Borrower,
execute such documents and take such actions as may be reasonably requested

                            ARTICLE 12: ARBITRATION

         Section 12.1 ARBITRATION.

                  (a) The Borrower and Lender and any other obligor party (the
         "PARTIES") will attempt in good faith to resolve any controversy or
         dispute arising out of or relating to this Agreement promptly by
         negotiations between themselves. The negotiation process may be started
         by the giving of written notice by any party to the other parties in
         accordance with the terms of SECTION 11.3 hereof, and the parties agree
         to negotiate in good faith, and select an independent mediator to
         facilitate the negotiations and conduct up to eight consecutive hours
         of mediated negotiations in Houston, Texas within thirty (30) days
         after the notice is first sent. If, within ten (10) days after the
         initial notice, the parties are not able to agree upon a mediator, the
         parties shall immediately proceed to arbitration. Fees and expenses of
         the mediator shall be borne equally by the Borrower and Lender.

                  (b) No litigation or other proceeding may ever be instituted
         at any time in any court for any purpose, except as may be set forth in
         SECTION 12.1(h) hereof.

                  (c) If a controversy or dispute is not resolved after
         completion of the negotiation process described in SUBSECTION (a)
         above, then, upon notice by any party to the other parties (an
         "ARBITRATION NOTICE") and to AAA, the controversy or dispute shall be
         submitted to an arbitration panel for binding arbitration in Houston,
         Texas, in accordance with AAA's Commercial Arbitration Rules (the
         "RULES"). The parties agree that they will faithfully observe this
         Agreement and the Rules and that they will abide by and perform any
         award rendered by the arbitration panel. The arbitration shall be
         governed by the Federal Arbitration Act, 9 U.S.C. Section 1-16. The
         award or judgment of the arbitration panel shall be final and binding
         on all parties and judgment upon the award or judgment of the
         arbitration panel may be entered and enforced by any court having
         jurisdiction. If any party becomes the subject of a bankruptcy,
         receivership or other similar proceeding under the laws of the United
         States of America, any state or commonwealth or any other nation or
         political subdivision thereof, then, to the extent permitted or not
         prohibited by applicable law, any factual or substantive legal issues
         arising in or during the pendency of any such proceeding shall be
         subject to all of the foregoing mandatory mediation and arbitration
         provisions and shall be resolved in accordance therewith. The
         agreements contained herein have been given for valuable consideration,
         are coupled with an interest and are not intended to be executory
         contracts. The fees and expenses of the arbitration panel will be
         shared by all parties engaged in the dispute or controversy on a basis
         determined to be fair and equitable by the arbitrators, taking into
         account the relative fault of each party, the relative credibility and
         merit of all claims and defenses made by each party and the
         cooperation, speed and efficiency of each party in conducting the
         arbitration proceeding and complying with the Rules and with orders and
         requests of the arbitrators.

                  (d) Promptly after the Arbitration Notice is given, each party
         will select an arbitrator and the arbitrators so selected will in turn
         select an independent and impartial third arbitrator. If the
         arbitrators selected by the parties are unable to agree on a third

                                       55

<PAGE>

         arbitrator, then one of the parties shall notify AAA and AAA shall
         select the third arbitrator. Such third arbitrator selected in such
         manner shall not be entitled to compensation in excess of compensation
         paid to either of the other two arbitrators. The decision of AAA with
         respect to the selection of the third arbitrator will be final and
         binding in such case. Such three arbitrators will constitute the
         arbitration panel. Any arbitration regarding the Purchase Price for the
         Overriding Royalty Interest shall be conducted by arbitrators who are
         petroleum engineers employed by one or more of the firms designated in
         SECTION 7.1(f) hereof.

                  (e) Within 10 days after the selection of the arbitration
         panel, the parties and their counsel will appear before the arbitration
         panel at a place and time in Houston, Texas, as may be designated by
         the arbitration panel for the purpose of each party making a one hour
         or less presentation and summary of the case. Thereafter, the
         arbitration panel will set dates and times for additional hearings
         until the proceeding is concluded. The desire and goal of the parties
         is, and the arbitration panel will be advised that its goal should be,
         to conduct and conclude the arbitration proceeding as expeditiously as
         possible.

                  (f) Any arbitral award may be enforced in a District Court of
         the State of Texas sitting in Houston, Texas or in the United States
         District for the Southern District of Texas, Houston Division, and, by
         execution and delivery of this Agreement, the parties hereby accept for
         themselves and in respect of their property, generally and
         unconditionally, the nonexclusive jurisdiction of the aforesaid courts
         for said purpose and the parties hereby irrevocably waive to the
         fullest extent permitted by law any objection, including without
         limitation, any objection to the laying of venue or based on the
         grounds of forum non conveniens, which they may now or hereafter have
         to the bringing of any such action or proceeding in such respective
         jurisdictions.

                  (g) The arbitration panel will have no authority to award
         punitive or other damages not measured by the prevailing party's actual
         damages and may not, in any event, make any ruling, finding, or award
         that does not conform to the terms and conditions of this Agreement.

                  (h) The provisions of this SECTION 12.1 relating to
         arbitration of disputes shall not apply to litigation or any other
         submission to judicial or administrative process that is instituted for
         the sole purpose of: (i) compelling a party to submit to arbitration in
         accordance with the provisions of this SECTION 12.1, (ii) obtaining
         enforcement of any award or judgment of the arbitrator(s) issued
         pursuant to this SECTION 12.1, (iii) accelerating the maturity of any
         debt of the Borrower during the continuance of an Event of Default,
         (iv) bringing suit and obtaining a judgment against the Borrower on its
         debt for purposes of enforcement of any Security Document (provided
         that the satisfaction of such judgment is limited solely to the
         Collateral), or (v) exercising all of the Lender's rights and remedies
         to foreclose or otherwise realize upon the Collateral, including rights
         to collect sums due or to become due under the Collateral.

                  (i) The provisions of this ARTICLE 12 shall terminate
         immediately if, as and when the party originally identified herein as
         "Lender" no longer owns any rights or interests under this Agreement
         and the Obligations of the Borrower arising pursuant hereto;

                                       56

<PAGE>

         provided that if any arbitration under the provisions of this Article
         has been initiated prior to the time that such Lender no longer owns
         any such rights or interests under this Agreement and the Obligations,
         the provisions of this Article shall continue to be applicable to any
         such arbitration that has been commenced.
