                                  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.

                                       5
<PAGE>
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 half 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.



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 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.

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

                                       13
<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.

                                       15
<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

                                       16
<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

                                       19
<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;

                                       20
<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.

                                       21
<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 computer aided
exploration technologies, commonly referred to as CAEX technology. The 3-D
seismic data, when completed, will cover over 820 square miles. CAEX technology
is the use of powerful computer workstations and software to collect, organize,
analyze and interpret geological and geophysical data obtained from seismic
surveys and petrophysical and downhole log data obtained from previously drilled
wells. 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

                                       23
<PAGE>
$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 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.

                                       24
<PAGE>
    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 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

                                       25
<PAGE>
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 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.

                                       26
<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:

      negotiating such purchase in exchange for Preferred Stock.


    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 drilling a test well in May
1998 and completed the well in November 1998 as a Cotton Valley discovery.

                                       28
<PAGE>
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.


    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.

- ------------------------

(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, 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 reserves" are the estimated quantities of crude oil, natural gas,
    and natural gas liquids which geological and engineering data demonstrate
    with reasonable certainty to be recoverable in future years from known
    reservoirs under existing economic and operating conditions, I.E., prices
    and costs as of the date the estimate is made. Prices include consideration
    of changes in existing prices provided only by contractual arrangements, but
    not on escalations based upon future conditions.



    Reservoirs are considered proved if economic producibility is supported by
    either actual production or conclusive formation test. The area of a
    reservoir considered proved includes (A) that portion delineated by drilling
    and defined by gas-oil and/or oil-water contacts, if any; and (B) the
    immediately adjoining portions not yet drilled, but which can be reasonably
    judged as economically productive on


                                       30
<PAGE>

    the basis of available geological and engineering data. In the absence of
    information on fluid contacts, the lowest known structural occurrence of
    hydrocarbons controls the lower proved limit of the reservoir.



    Reserves which can be produced economically through application of improved
    recovery techniques (such as fluid injection) are included in the "proved"
    classification when successful testing by a pilot project, or the operation
    of an installed program in the reservoir, provides support for the
    engineering analysis on which the project or program was based.



    "Proved developed reserves" means reserves that can be expected to be
    recovered through existing wells with existing equipment and operating
    methods, including oil and gas expected to be obtained through the
    application of fluid injection or other improved recovery techniques for
    supplementing the natural forces and mechanisms of primary recovery after
    testing by a pilot project or after the operation of an installed program
    has confirmed through production response that increased recovery will be
    achieved.



    "Proved undeveloped reserves" means reserves that are expected to be
    recovered from new wells on undrilled acreage, or from existing wells where
    a relatively major expenditure is required for recompletion. Proved
    undeveloped reserves on undrilled acreage are limited to those drilling
    units offsetting productive units that are reasonably certain of production
    when drilled. Proved undeveloped reserves for other undrilled units are
    included only where it can be demonstrated with certainty that there is
    continuity of production from the existing productive formation.



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



    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 for being exact.

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.

(1) An "exploratory well" is a well drilled to find and produce oil or gas in an
    unproven area, to find a new reservoir in a field previously found to be
    productive of oil or gas in another reservoir or to extend a known
    reservoir.



(2) A "development well" is a well drilled within the proved area of an oil or
    gas reservior to the depth of a stratograph horizon known to be productive.


    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.

    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 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

                                       35
<PAGE>
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 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.

                                       36
<PAGE>
    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 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-

                                       37
<PAGE>
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;

    - 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.

                                       38
<PAGE>
        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.

        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.

                                       39

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 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.


    During the fourth quarter of 1998, we notified Mr. LaFlure of our intent to
terminate his employment. The principal terms of his termination were agreed
upon in 1998. Discussions included a settlement based on the terms of his
employment agreement. Final details were agreed upon in early 1999 and we
terminated Mr. LaFlure's employment without cause effective January 15, 1999.
Mr. LaFlure was requested 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.

                                       43
<PAGE>
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 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.

OPTION GRANTS

    No options were granted to our executive officers in 1998.

                              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

                                       45
<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

                                       46
<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.


    COSTS OF THE LASCO, CALIBRE AND STARBUCKS ACQUISITIONS.  The values of the
Lasco, Calibre and Starbucks properties, using the future pretax cash flows
discounted at 10% of the properties, were estimated at $10.8 million, after
adjustment, $16.7 million and $4.7 million, respectively. The assets acquired in
these transactions were acquired by the sellers during the two years before the
acquisition by the Company. The Starbucks and Calibre acquisitions were reveiwed
and approved by an independent committee of the Board of Directors. The Calibre
assets had a cost basis of $4.1 million. The Starbucks assets had a cost basis
of $.8 million. The Lasco assets had a cost basis of $12.8 million.


    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

                                       47
<PAGE>
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 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.

    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.

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.

                                       53

    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

                                       55
<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.

                                       56
<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.

                                       57
<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>

Net assets acquired.............................................................  $ 5,342,158

                                                                                  -----------
</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:

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

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

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

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
arrears in equal semi-annual installments on March 31st and September 30th of
each year. The debentures have a maturity date of March 31, 2003. The debentures
are convertible at the option of the holder into the Company's Common

Stock prior to March 27, 2003 at a conversion price of Cdn.$1.70 per share,
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
upon the exercise of the Special Notes and (ii) the date 18 months after the
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.

    COGNISEIS DEVELOPMENT.  On May 1, 1996, Texstar LLC purchased equipment and
financed the purchase through the vendor. The amount financed was $110,365. As

    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.

NOTE 16. RELATED PARTY TRANSACTIONS (CONTINUED)
    During the four-month period ended December 31, 1997, the Company made

off as of December 31, 1997. During the year ended December 31, 1998, the
Company made advances to Calibre Ecuador of $319,327. These advances were
written off during the year.

    Additionally, during the four-month period ended December 31, 1997, the
Company's net advances to Calibre increased to $1,768,772. At December 31, 1997,
$1,450,000 of this amount was reclassified as a prepayment relating to the
acquisition of properties from Calibre. The balance of $318,772 was written off
as a bad debt.

    The Company participates in various oil and gas activities with related
parties. All transactions related to such activities are in the normal course of
business. As of December 31, 1998 and 1997, balances with related parties were

    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.

NOTE 22. SUBSEQUENT EVENTS

    The following events took place subsequent to December 31, 1998:

    - 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
      the swap was based on the 10 day trailing closing average through March 26
      1999.

    - Effective March 31, 1999, a certain debenture holder has agreed to
      exchange $250,000 of debentures for 541,700 common shares.

    - The Company and Series 1 debenture holders have agreed to lower the
      conversion price of the debentures from Cdn.$1.70 per common share to

      indenture agreement. The Company intends to approach the Series 3
      debenture holders and Series B Special Note holders for the same changes.
      The Company has approached the Series 1 debenture holders to exchange
      their debentures for non-redeemable convertible preferred stock in
      exchange for new equity to be placed into the Company. The Company intends
      to similarly approach the Series 3 Debenture holders. The early redemption
      provision of the redeemable preferred stock decribed in Note 12 relating
      to a qualified public offering of the Company's common stock was waived by
      the holder in May 1999 subject to the completion of the exchange offer.

    - The Company is in negotiations with Pioneer Natural Resources to structure
      a plan to pay the balance owing Pioneer (approximately $4 million).

      issuing a promissory note for payment over an extended period, paying a
      portion in cash or trading prospects for some or all of the amounts due.

    - The first payment to Western under the Western Geophysical contract
      (estimated $3.35 million) in Old Ocean has been deferred by Western to
      approximately June 10, 1999. The Company paid $700,000 on June 18, 1999
      and $2.6 million on July 9, 1999. The Company has reached an oral
      agreement to pay the remaining balance of approximately $3.4 million by
      July 31, 1999.

    - The Company sold its Lisbon properties for proceeds of $507,500 in April
      1998.

    - On May 18, 1999, the Company migrated from the Yukon Territory, Canada and

      of amounts due them. These amounts are reflected in the Company's accounts
      payable.

    - In August 1999, the Company sold 37.5% of its interest in the Old Ocean
      Prospect for approximately $5.5 million. The purchaser has the option to

NOTE 22. SUBSEQUENT EVENTS (CONTINUED)
     provisions relating to the overriding royalty interests in the prospect and
      the marketing of 3-D seismic geophysical data covering the prospect.

    - In July, 1999, 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 Mobil
      financing described in Note 9 and the re-conveyance of the applicable net
      profits interest. The balance of the financing and re-conveyance was
      settled through a cash payment.

    - 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 and issued an aggregate of 238,201 shares of class
      A, series II preferred stock, which included 44,600 shares issued under
      the primary offering and the remainder of which were issued pursuant to
      the exchange offer. The proceeds from the exchange offer and offering of
      convertible preferred stock were used to retire a portion of the Mobil
      financing, to repurchase a portion of the Old Ocean net profits interest,
      to pay a portion of the seismic costs relating to the Old Ocean Prospect
      and to pay fees and expenses of the transactions.


    - In August 1999, the Company completed a new, long-term production
      financing in the amount of $26.2 million. This amount may be increased to
      $27.7 million, based on certain short-term production results. This
      facility also provides for the lender to fund additional drilling in the
      Oakvale Dome field to a maximum of $3.8 million and the option to fund
      $1.1 million for the drilling of one additional well. The new production
      financing is secured by the 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 Company's proven properties, following full
      repayment. Proceeds from the financing were used to retire existing debt
      and accrued interest.


    - In August 1999, the Company completed a private placement of $4 million in
      new equity through this issuance of $4.4 million of redeemable class A
      preferred stock, series I to investment entities affiliated with and
      managed by EnCap L.C. A placement fee of $100,000 was paid to EnCap L.C.
      Proceeds were used to fund arrangements under the credit agreement
      described below and for other general corporate purposes.

    - The Company conducted a meeting with its trade creditors to outline a
      proposed repayment plan for past due amounts. The plan includes proposed
      discounts, payment over an extended time with interest and other options.
      As of September 8, 1999, creditors electing to participate in the
      repayment plan represented approximately 93% of past due amounts for an
      aggregate of approximately $11.3 million.

    - The Company entered into a new promissory note with EnCap in the amount of
      approximately $2.9 million. The note matures on December 31, 2000 and
      accrues interest at a rate of 10% per year.

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.

    FUTURE NET CASH FLOWS--Future cash inflows are based on year-end prices
except in those instances where the sale of natural gas or oil is covered by
physical or derivative contract terms providing for higher or lower amounts.
Operating costs, production and ad valorem taxes and future development costs
are based on current costs with no escalation.

    The following table sets forth unaudited information concerning future net
cash flows for oil and gas reserves, net of income tax expense. Income tax
expense has been computed using expected future tax rates and giving effect to
tax deductions and credits available, under current laws, and that relate to oil
and gas producing activities. This information does not purport to present the

    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.

                                  (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.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Partners of Lasco Energy Partners, L.P., and
  The Board of Directors and Stockholders of Benz Energy Ltd.

    We have audited the accompanying Statement of Revenues and Direct Operating
Expenses of the Oak Hill and Lisbon Properties for the period from acquisition
by Lasco Energy Partners, L.P. (August 14, 1996) to December 31, 1996 and for
the year ended December 31, 1997. This statement is the responsibility of the
management of the owners of the properties. Our responsibility is to express an
opinion on the statement based on our audits.

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

    The accompanying statement as described in Notes 1 and 2 was prepared for
the purpose of complying with certain rules and regulations of the Securities
and Exchange Commission for inclusion in a registration statement on Form SB-2
to be issued in connection with an offering by Benz Energy Ltd. under the
Securities Act of 1933. It is not intended to be a complete presentation of the
financial condition, operations and cash flows of the properties.

    In our opinion, the statement audited by us presents fairly, in all material
respects, the revenues and direct operating expenses of the Oak Hill and Lisbon
Properties as described in Notes 1 and 2 for the period from inception to
December 31, 1996 and for the year ended December 31, 1997, in conformity with
generally accepted accounting principles.

              NOTES TO STATEMENT OF REVENUES AND DIRECT OPERATING
                 EXPENSES OF THE OAKHILL AND LISBON PROPERTIES

NOTE 1--THE PROPERTIES

    On January 23, 1998, and effective December 1, 1997, Benz Energy Ltd.
("Benz") purchased interests in Oakhill and Lisbon oil and gas properties
located in Texas and Louisiana, respectively (the Properties) from Lasco Energy
Partners, L.P. (Lasco or the Partnership). Only the Partnership's net interests
in these properties are presented herein and are referred to as the Properties.

NOTE 2--BASIS OF PRESENTATION

    During the periods presented, the Properties were not accounted for as a
separate entity. Certain costs were not allocated to the Properties by Lasco.
Accordingly, full separate financial statements prepared in accordance with
generally accepted accounting principles do not exist and are not practicable to
obtain in these circumstances.

    The Statement of Revenues and Direct Operating Expenses (the "Statement")
was derived from the historical accounting records of the Partnership and
represents only the net interests in the Properties acquired by Benz.
Depreciation, depletion and amortization, general and administrative expenses
and other non-operating expenses are not included. Accordingly, the Statement is
not intended to present financial position and results of operations in
accordance with generally accepted accounting principles.

    Revenues in the Statement are recognized on the entitlement method.

    The accompanying Statement has been prepared on the accrual basis in
accordance with generally accepted accounting principles. Preparation of the
Statement in conformity with generally accepted accounting principles and
estimation of oil and gas reserves require management to make estimates and
assumptions that affect the amounts reported in the Statement and accompanying
notes. Actual results could differ from those estimates.

NOTE 3--RELATED PARTY TRANSACTIONS

    Willow Springs Production Services, L.L.C. ("WSPS") had been the general
partner and operator of the Partnership from acquisition (August 14, 1996) to
August 31, 1997 when it was removed from this capacity. From September 1, 1997
to December 31, 1997, Riverhill Energy Corporation has been the general partner
and Coastal Management Corporation ("Coastal"), an affiliate of Riverhill Energy
Corporation, has been the operator. In their capacity as the operators for the
related periods, as stated above, WSPS and Coastal receive certain revenues and
pay expenses associated with the Lasco's properties and then allocate such
activity as appropriate to the respective working interest and royalty owners.
The two limited partners in the Partnership were EnCap Equity 1996 Limited
Partnership and Energy Capital Investment Company PLC. EnCap Investments L.C.
("EnCap") is the general partner of EnCap Equity 1996 Limited Partnership.

NOTE 4--COMMITMENT AND CONTINGENCIES

    In the course of their operations, the properties are subject to possible
contingencies arising from federal, state and local environmental, health and
safety laws and regulations. Additionally, the Properties were subject to
possible title issues which could affect the legal title of Benz to the
Properties. There are no such matters which, in the opinion of Encap management,
will have a material adverse impact on the revenues and direct operating
expenses in the Statement.

NOTE 4--COMMITMENT AND CONTINGENCIES (CONTINUED)
    While there are certain claims related to the Properties and operations of
the Partnership, none of these matters, in the opinion of EnCap management,
could have a material adverse effect on the revenues and direct operating
expenses in the Statement.

NOTE 5--SUPPLEMENTAL OIL AND GAS INFORMATION (UNAUDITED)

    OIL AND GAS RESERVE INFORMATION--Proved oil and gas reserve quantities are
based on estimates prepared by the Company's engineers in accordance with
guidelines established by the Securities and Exchange Commission ("SEC"). There
are numerous uncertainties inherent in estimating quantities of proved reserves
and projecting future rates of production and timing of development
expenditures. The following reserve data represent estimates only and should not
be construed as being exact.

authority conferred upon the Board of Directors by the Certificate of
Incorporation, as amended, and pursuant to Section 151, 242, 141 and 228 of the
DGCL, that the Class A Preferred Stock, Series I shall have the powers and

                            "CLASS A PREFERRED SHARES

     Section 1.1    Directors' Authority to Issue in One or More Series

     The board of directors of the Corporation may issue the Class A Preferred
shares at any time and from time to time in one or more series.  Before the
first shares of a particular series are issued, the board of directors of the
Corporation shall fix the number of shares in such series and shall determine,
subject to the limitations set out in the articles, the designation, rights,
privileges, restrictions and conditions to be attached to the shares of such
series including, without limitation, the rate of rates, amount or method or
methods of calculation of dividends thereon, the time and place of payment of
dividends, whether cumulative or non-cumulative or partially cumulative and
whether such rate, amount or method of calculation shall be subject to change or
adjustment in the future, the currency or currencies of payment of dividends,
the consideration and the terms and conditions of any purchase for cancellation,
retraction or redemption (if any), the conversion, exchange or reclassification
rights attached thereto (if any), the voting rights attached thereto (if any),
the terms and conditions of any share purchase plan or sinking fund with respect
thereto, and any other terms not inconsistent with these provisions.  Before the
issue of the first shares of a series, the board of directors of the Corporation
shall execute, acknowledge, file and cause to become effective, in accordance
with Section 103 of DGCL, a certificate of designation setting forth a copy of
such resolution or resolutions adopted by the Board of Directors and the number
of shares of stock of such series as to which the resolution or resolutions
apply containing a description of such series including the designation, rights,
privileges, restrictions and conditions determined by the Board of Directors of
the Corporation.

<PAGE>

     Section 1.2    RANKING OF CLASS A PREFERRED SHARES

     No rights, privileges, restrictions or conditions attached to a series of
Class A Preferred shares shall confer upon a series a priority in respect of
dividends or return of capital over any other series of Class A Preferred shares
then outstanding.  The Class A Preferred shares shall be entitled to priority
over the common shares of the Corporation and over any other shares of the
Corporation ranking junior to the Class A Preferred shares with respect to
priority in the payment of dividends and the distribution of assets in the event
of the liquidation, dissolution or winding-up of the Corporation, whether
voluntary or involuntary, or any other distribution of the assets of the
Corporation among its shareholders for the purpose of winding-up its affairs.
If any cumulative dividends or amounts payable on a return of capital in respect
of a series of Class A Preferred shares are not paid in full, the Class A
Preferred shares of all series shall participate rateably in respect of such
dividends, including accumulations, if any, in accordance with the sums that
would be payable on such shares if all such dividends were declared and paid in
full, and in respect of any repayment of capital in accordance with the sums
that would be payable on such repayment of capital if all sums so payable were
paid in full; provided however, that in the event of there being insufficient
assets to satisfy in full all such claims to dividends and return of capital,
the claims of the holders of the Class A Preferred shares with respect to
repayment of capital shall first be paid and satisfied and any assets remaining
thereafter shall be applied towards the payment and satisfaction of claims in
respect of dividends.  The Class A Preferred shares of any series may also be
given each other preferences, not inconsistent with sections 1.1 to 1.4 hereof,
over the common shares and over any other shares ranking junior to the Class A
Preferred shares as may be determined in the case of such series of Class A
Preferred shares.

     Section 1.3    VOTING RIGHTS

     Except as hereinafter referred to or as otherwise required by law or in
accordance with any voting rights which may from time to time be attached to any
series of Class A Preferred shares, the holders of the Class A Preferred shares
as a class shall not be entitled as such to receive notice of, to attend or to
vote at any meeting of the shareholders of the Corporation.

     Section 1.4    APPROVAL OF HOLDERS OF CLASS A PREFERRED SHARES

     The rights, privileges, restrictions and conditions attaching to the Class
A Preferred shares as a class may be added to, changed or removed but only with
the approval of the holders of the Class A Preferred shares given as hereinafter
specified.

     The approval of the holders of Class A Preferred shares to add to, change
or remove any right, privilege, restriction  or condition attaching to the Class
A Preferred shares as a class or to any other matter requiring the consent of
the holders of the Class A Preferred shares as a class may be given in such
manner as may then be required by law, subject to a minimum requirement that
such approval shall be given by resolution passed by the affirmative voice of at
least two-thirds of the votes cast at a meeting of the holders of Class A
Preferred shares duly called for that purpose.  The formalities to be observed
in respect of the giving of notice of any such meeting or any adjourned meeting
and the conduct thereof shall be these from time to time required by the DGCL
and prescribed in the by-laws of the Corporation with respect to meetings of
shareholders.  On every poll taken at a meeting of holders of Class A Preferred
shares as a class, each holder entitled to vote thereat shall have one vote

                                       3

in respect of each $1.00 of stated capital added to the appropriate stated

individual whose signature (either manual or in facsimile) may appear on the
Debentures is not, at the date of this Indenture or at the date of the
Debentures or at the date of the certifying and delivery thereof the
Chairman, the President, a Vice President, the Secretary, the Treasurer, an
Assistant Secretary or an Assistant Treasurer or Controller, as the case may
be, of the Corporation, such Debentures shall be valid and binding upon the
Corporation and entitled to the benefits of this Indenture.

2.6      CERTIFICATION

No Debenture shall be issued or, if issued, shall be obligatory or shall
entitle the Holder thereof to the benefits of this Indenture until it has
been certified by or on behalf of the Trustee substantially in the form
approved by the Trustee, whose approval shall be conclusively evidenced by
the certification thereof. Such certificate on any Debenture shall be
conclusive evidence that such Debenture is duly issued and is a valid
obligation of the Corporation.

                                     - 10 -

The certificate of the Trustee on any Debenture shall not be construed as a
representation or warranty by the Trustee as to the validity of this
Indenture or of the Debentures (except the due certification thereof) and the
Trustee shall in no respect be liable or answerable for the use made of the
Debentures or any of them or the proceeds thereof.

2.7      CONCERNING INTEREST

         (a)  Any Coupons which have matured at the date of delivery by the
              Trustee of any Bearer Debenture shall be detached from the same
              and cancelled before delivery, unless such Bearer Debenture is
              being issued in exchange or in substitution for another Bearer
              Debenture and such matured Coupons represent unpaid interest to
              which the Holder of such exchanged or substituted Debenture is
              entitled.

         (b)  Every Registered Debenture of any series issued prior to the
              first Interest Payment Date for such series in exchange or
              substitution for, or upon the transfer of, the whole or any
              part of one or more other Debentures of the same series,
              bearing the same rate of interest and having the same Interest
              Payment Dates and Stated Maturity, shall be dated as of the
              date from which interest is payable on such other Debenture or
              Debentures and every Registered Debenture issued after the
              first Interest Payment Date for such series in exchange or
              substitution for, or upon the transfer of, the whole or any
              part of one or more other Debentures of the same series bearing
              the same rate of interest and having the same Interest Payment
              Dates and Stated Maturity, shall be dated as of the Interest
              Payment Date next preceding the date of certification thereof
              to which interest has been paid on the Debentures of such
              series, unless the date of certification is an Interest Payment
              Date to which interest has been paid, in which case it shall be
              dated as of the date of certification. Every Registered
              Debenture shall bear interest from its date. Nevertheless in
              the case of any Registered Debenture issued originally, or upon
              exchange, substitution, transfer or otherwise, if the dating of
              such Debenture as of the actual date of certification would
              result in the Holder either losing or gaining interest, the
              Trustee shall date such Debenture such date, other than the
              actual date of certification, as will prevent any such loss or
              gain, and such Debenture shall bear interest in accordance with
              the foregoing provisions of this section 2.7.

2.8      DEBENTURES TO RANK EQUALLY

The Debentures may be issued in such amounts, to such Persons, on such terms not
inconsistent with the provisions of this Indenture, and either at par or at a
discount or at a premium as the Directors may determine. The Debentures shall be
direct obligations of the Corporation, shall rank pari passu without
discrimination, preference or priority with one another and with other unsecured
and unsubordinated indebtedness for borrowed money of the Corporation. Each
Debenture as soon as issued shall, subject to the terms hereof, be equally and
rateably entitled to the benefits hereof as if all the Debentures had been
issued and negotiated simultaneously.

2.9      REGISTRATION OF DEBENTURES

         (a)  The Corporation shall cause to be kept by and at the principal
              office of the Trustee in the City of Calgary a central
              register, and by and at the principal office of the Trustee in
              each of the cities of Vancouver, Calgary and Toronto and in
              such other place or places by the Trustee or by such other
              registrar or registrars, if any, as the Corporation with the
              approval of the Trustee may designate, branch registers in
              which shall be entered the names and latest known addresses of
              the Holders of Registered Debentures and the other particulars,
              as prescribed by law, of the Debentures held by them
              respectively and of all transfers of Registered Debentures.
              Such registration shall be noted on the Debentures by the
              Trustee or other registrar. No transfer of a Registered
              Debenture shall be effective as against the Corporation unless
              made on one of the appropriate registers by the Holder of such
              Registered Debenture or his executors or administrators or
              other legal representatives or his or their attorney duly
              appointed by an instrument in form and execution satisfactory
              to the Trustee

<PAGE>

                                     - 11 -

              and upon compliance with such requirements as the Trustee or
              other registrar may prescribe, and unless such transfer shall
              have been duly noted on such Debenture by the Trustee or other
              registrar.

         (b)  The registers referred to in this section shall at all
              reasonable times be open for inspection by the Corporation, the
              Trustee and any Debentureholder.

         (c)  The Holder of a Registered Debenture may at any time and from
              time to time have such Debenture transferred at any of the
              places at which a register is kept pursuant to the provisions
              of this section in accordance with such reasonable regulations
              as the Trustee may prescribe. The Holder of a Registered
              Debenture may at any time and from time to time have the
              registration of such Debenture transferred from the register in
              which the registration thereof appears to another register
              maintained in another place authorized for that purpose under
              the provisions of this Indenture upon payment of a reasonable
              fee to be fixed by the Trustee.

         (d)  Neither the Corporation nor the Trustee nor any registrar shall
              be required to transfer or exchange any Registered Debentures
              on any Interest Payment Date or during the 15 Business Days
              immediately preceding any Interest Payment Date.

         (e)  None of the Trustee, any registrar for any of the Registered
              Debentures and the Corporation shall be charged with notice of
              or be bound to see to the execution of any trust, whether
              express, implied or constructive, in respect of any Registered
              Debenture and may transfer any Registered Debenture on the
              direction of the Holder thereof, whether named as trustee or
              otherwise, as though that Person were the beneficial owner
              thereof.

         (f)  Except in the case of the central register required to be kept
              at the city of Calgary, the Corporation shall have power at any
              time to close any branch register and in that event it shall
              transfer the records thereof to another existing register or to
              a new register and thereafter such Debentures shall be deemed
              to be registered on such existing or new register, as the case
              may be. In the event that the register in any place is closed
              and the records transferred to a register in another place,
              notice of such change shall be given to the Holders of the
              Registered Debentures registered in the register so closed and
              the particulars of such change shall be recorded in the central
              register required to be kept in the city of Calgary.

         (g)  Every registrar shall, when requested to do so by the
              Corporation or the Trustee, furnish the Corporation or the
              Trustee, as the case may be, with a list of the names and
              addresses of the Holders of Registered Debentures showing the
              principal amounts and serial numbers of such Debentures held by
              each Holder.

2.10     PAYMENT OF PRINCIPAL AND INTEREST IN RESPECT OF REGISTERED DEBENTURES

         (a)  As the interest on Registered Debentures of any series becomes
              due (except interest payable at Maturity which may be paid upon
              presentation and surrender of such Debentures for payment), the
              Corporation, at least three days prior to each date on which
              interest on such Debentures becomes due, shall forward or cause
              to be forwarded by first class mail, postage prepaid, (or in
              the event of mail service interruption by such other means as
              the Trustee and the Corporation shall determine to be
              appropriate) to the Holder for the time being at his address
              appearing on the appropriate register hereinbefore mentioned a
              cheque for such interest (less any tax required by law to be
              deducted) payable to the order of such Holder and negotiable at
              par at each of the places at which interest upon such
              Registered Debentures is payable. The forwarding of such cheque
              shall satisfy and discharge the liability for the interest on
              such Registered Debentures to the extent of the sum represented
              thereby (plus the amount of any tax deducted as aforesaid)
              unless such cheque is not paid on presentation. In the event of
              the non-receipt of such cheque by the Holder or the loss or
              destruction

<PAGE>

                                     - 12 -

              thereof, the Corporation, upon being furnished with evidence of
              such non-receipt, loss or destruction and an indemnity
              reasonably satisfactory to it, shall issue or cause to be
              issued to such Holder a replacement cheque for the amount of
              such cheque.

         (b)  Where Registered Debentures are registered in more than one
              name, the principal and interest from time to time payable in
              respect thereof shall be paid by cheque payable to the order of
              all such Holders, unless the Corporation has received written
              instructions from them to the contrary, and the receipt of any
              one of such Holders therefor shall be a valid discharge to the
              Trustee, any registrar of Debentures and the Corporation.

2.11     PAYMENT OF PRINCIPAL AND INTEREST IN RESPECT OF BEARER DEBENTURES

         (a)  Interest payments in respect of Bearer Debentures of any series
              shall be made (less any tax required by law to be deducted)
              against presentation and surrender of the appropriate Coupons
              at the place or places specified with respect to such series.

         (b)  Any payment of principal in respect of a Bearer Debenture shall
              be made against presentation and surrender of such Bearer
              Debenture, together with all unmatured Coupons (if any)
              appertaining thereto, failing which the amount of the missing
              unmatured Coupons will be deducted from the principal amount
              due for payment, at the place or places specified with respect
              to such series. Amounts of principal so deducted will be paid
              against surrender of the relevant missing Coupons within a
              period of six years from the date upon which such amount would
              otherwise have been payable.

         (c)  Interest payable in respect of any interest payment which is in
              default shall be paid to the Holder of the Coupon representing
              such interest payment and interest payable in respect of any
              other amount in default shall be paid to the Holder of the
              Bearer Debenture in respect of which such payment is due.

2.12     OWNERSHIP OF REGISTERED DEBENTURES

         (a)  The Person in whose name any Registered Debenture shall be
              registered shall be deemed to be the owner thereof for all
              purposes of this Indenture and payment of or on account of the
              principal of and interest on such Registered Debenture shall be
              made only to or upon the order in writing of the Holder thereof
              and such payment shall be a complete discharge to the Trustee,
              any registrar of Debentures, the Corporation and any Paying
              Agent for the amounts so paid.

         (b)  The Holder for the time being of any Registered Debenture shall
              be entitled to the principal, interest and premium, if any,
              evidenced by such Registered Debenture, free from all equities
              or rights of set-off or counterclaim between the Corporation
              and the original or any intermediate Holder thereof (except any
              equities of which the Corporation is required to take notice by
              law) and all Persons may act accordingly and a transferee of a
              Registered Debenture shall, after the appropriate form of
              transfer is lodged with the Trustee or other registrar of
              Debentures and upon compliance with all other conditions in
              that behalf required by this Indenture or by any conditions
              contained in such Registered Debenture or by law, be entitled
              to be entered on the appropriate register or on any one of the
              appropriate registers as the owner of such Registered Debenture
              free from all equities or rights of set-off or counterclaim
              between the Corporation and his transferor or any previous
              Holder thereof, save in respect of equities of which the
              Corporation is required to take notice by law.

2.13     NEGOTIABILITY AND OWNERSHIP OF BEARER DEBENTURES AND COUPONS

         (a)  Bearer Debentures and Coupons shall be negotiable and title
              thereto shall pass by delivery.

         (b)  Except as may be ordered by a court of competent jurisdiction
              or as required by law, the Corporation and the Trustee may deem
              and treat the bearer of any Bearer Debenture or Coupon as the
              absolute owner thereof for all purposes and none of the
              Corporation, the Trustee or any Paying Agent shall be affected
              by any notice to the contrary.

         (c)  The Holder of any Bearer Debenture and the bearer of any Coupon
              shall be entitled to the principal, interest or premium, if
              any, evidenced by such instrument free from all equities or
              rights of set-off or counterclaim between the Corporation and
              the original or any intermediate or subsequent Holder or bearer
              thereof (except any equities of which the Corporation is
              required to take notice of by law) and all persons may act
              accordingly and the receipt of any such Holder or bearer for
              any such principal or interest shall be a complete discharge to
              the Corporation and the Trustee for the same and none of the
              Corporation, the Trustee or any Paying Agent shall be bound to
              inquire into the title of any such Holder or bearer.

2.14     EXCHANGE OF DEBENTURES

         (a)  Bearer Debentures may be exchanged for Registered Debentures
              and Registered Debentures may be exchanged for Bearer
              Debentures (provided, in either case, that such Debentures are
              issuable), and Debentures of any denomination may be exchanged
              for Debentures of any other authorized denomination or
              denominations, any such exchange to be for Debentures of an
              equivalent aggregate principal amount of Debentures of the same
              series, carrying the same rate of interest and having the same
              Stated Maturity and the same redemption and sinking fund
              provisions, if any. Exchanges of Debentures may be made at the
              principal offices of the Trustee in the cities of Vancouver,
              Calgary and Toronto. Any Debentures tendered for exchange shall
              be surrendered to the Trustee and shall be cancelled. The
              Corporation shall execute, and the Trustee shall certify, all
              Debentures necessary to carry out such exchanges.

         (b)  Except as otherwise provided herein, upon any exchange of
              Bearer Debentures for Registered Debentures or Registered
              Debentures for Bearer Debentures or Debentures of any
              denomination for Debentures of any other authorized
              denominations and upon any transfer of Registered Debentures,
              the Trustee or other registrar of Debentures may make a
              sufficient charge to reimburse it for any stamp tax, security
              transfer tax or other governmental charge required to be paid,
              and in addition a reasonable charge for its services for each
              Debenture exchanged or transferred, and payment of such charges
              shall be made by the party requesting such exchange or transfer
              as a condition precedent thereto.

         (c)  Notwithstanding the foregoing, no charge (other than for
              insurance on any Debentures forwarded by mail) shall be made by
              the Trustee, any registrar of Debentures or the Corporation (i)
              for any exchange, registration or transfer of any Debenture
              applied for within a period of 30 days from the date hereof; or
              (ii) for any exchange, after such period, of Debentures for
              Debentures in lesser denominations, provided that the
              Debentures surrendered for exchange shall not have been issued
              as a result of any previous exchange, other than an exchange
              pursuant to clause (i) of this subsection or section 3.7.

         (d)  Bearer Debentures surrendered for exchange shall be accompanied
              by all unmatured Coupons appertaining thereto and Bearer
              Debentures issued on an exchange shall have detached therefrom
              and cancelled all Coupons appertaining thereto which have
              matured and in respect of which the interest has been paid.
              Each Debenture delivered under this Indenture in exchange for
              or in lieu of

<PAGE>

                                     - 14 -

              any other Debenture shall carry the rights to principal and
              interest accrued and unpaid, and to accrue, which were carried
              by such other Debenture.

         (e)  Neither the Corporation, the Trustee nor any other registrar of
              Debentures shall be required to make exchanges of Debentures on
              any Interest Payment Date or during the 15 Business Days
              immediately preceding any Interest Payment Date.

2.15     REPLACEMENT OF DEBENTURES AND COUPONS

If any of the Debentures or Coupons shall become mutilated or be lost, stolen or
destroyed and in the absence of notice that such Debentures have been acquired
by a bona fide purchaser within the meaning of the BUSINESS CORPORATIONS ACT
(Yukon), the Corporation in its discretion may issue, and thereupon the Trustee
shall certify and deliver, a new Debenture or Coupon upon surrender and
cancellation of the mutilated Debenture or Coupon, or, in the case of a lost,
stolen or destroyed Debenture or Coupon, in lieu of and in substitution for the
same, and the substituted Debenture or Coupon shall be in a form approved by the
Trustee and shall be entitled to the benefits of this Indenture equally with all
other Debentures or Coupons issued or to be issued hereunder. Each Debenture
delivered under this Indenture in exchange for or in lieu of any other Debenture
shall carry the rights to principal and interest accrued and unpaid, and to
accrue, which were carried by such other Debenture. In case of loss, theft or
destruction the applicant for a new Debenture or Coupon shall furnish to the
Corporation and to the Trustee such evidence of such loss, theft or destruction
as shall be satisfactory to them in their discretion and shall also furnish an
indemnity in amount and form satisfactory to them in their discretion. The
applicant shall pay all expenses incidental to the issuance of any such new
Debenture or Coupon.

2.16     INTERIM DEBENTURES

Pending delivery to the Trustee of definitive Debentures of any series or
part of a series, the Corporation may execute in lieu thereof (but subject to
the same provisions, conditions and limitations), and the Trustee may
certify, interim printed, mimeographed or typewritten Debentures, in such
form and in such denominations as may be approved by the Trustee and the
Chairman, the President or a Vice President of the Corporation (whose
certification or signature, either manual or in facsimile, as the case may
be, on any such interim Debentures shall be conclusive evidence of such
approval) entitling the Holders thereof to definitive Debentures of such
series or part of a series in any authorized denominations when the same are
ready for delivery, without expense to such Holders, but the total amount of
interim Debentures of any series or part of a series so issued shall not
exceed the aggregate principal amount of Debentures of such series or part of
a series for the time being authorized. Forthwith after the issuance of any
such interim Debentures the Corporation shall cause to be prepared the
appropriate definitive Debentures for delivery to the Holders of such interim
Debentures.

Interim Debentures which have been duly issued shall, until exchanged for
definitive Debentures, entitle the Holders thereof to rank for all purposes
as Debentureholders and otherwise in respect of this Indenture to the same
extent and in the same manner as though such exchange had actually been made.
When exchanged for definitive Debentures such interim Debentures shall
forthwith be cancelled by the Trustee. Any interest paid upon interim
Debentures shall be noted thereon by the Paying Agent at the time of payment
unless paid by cheque to the Holders thereof.

2.17     OPTION OF HOLDER AS TO PLACE OF PAYMENT

Except as otherwise provided herein, all sums which may at any time become
payable, whether at Maturity or on a declaration by the Trustee pursuant to
section 6.3 or on redemption or otherwise, on account of any Debenture or
Coupon or any principal, interest or premium shall be payable at the option
of the Holder or the bearer thereof at any of the places at which the
principal of and interest or premium (if any) on such Debenture or Coupon are
payable.

2.18     PAYMENT AGREEMENTS FOR DEBENTURES

Notwithstanding anything contained herein, the Corporation may enter into an
agreement with the Holder of a Registered Debenture or with the Person for
whom such Holder is acting as nominee providing for the payment to such
Holder of the principal of and interest or premium (if any) on such Debenture
at a place or places other than the place or places specified herein or any
supplemental indenture and in such Debenture as the place or places for such
payment. Any payment of the principal of and interest or premium (if any) on
any such Registered Debenture at such other place or places pursuant to such
agreement shall, notwithstanding any other provision of this Indenture or any
supplemental indenture, be valid and binding on the Corporation, the Trustee
and the Holders of Debentures.

                                   ARTICLE 3
          REDEMPTION AND PURCHASE FOR CANCELLATION OF THE DEBENTURES

3.1      GENERAL

The Corporation, when not in default hereunder, shall have the right at its
option to redeem, either in whole at any time or in part from time to time
before Maturity, Debentures issued hereunder of any series or part of a
series which by their terms are made so redeemable at such rate or rates of
premium, if any, and at such date or dates and on such terms and conditions
as shall have been determined at the time of the issue of such Debentures and
as shall be expressed in this Indenture and/or in the Debentures and/or in
the supplemental indenture authorizing or providing for the issue thereof.

"Premium" as used in this Article 3 with reference to any Debenture shall
mean the excess of the then applicable redemption price of such Debenture
(excluding interest) over the principal amount of such Debenture.

3.2      NOTICE OF REDEMPTION

Notice of intention to redeem any Debenture shall be given by or on behalf of
the Corporation to the Holders of the Debenture which are to be redeemed, not
more than 60 days nor less than 30 days prior to the date fixed for
redemption, in the manner provided in section 10.2. Every notice of
redemption shall designate the series and Stated Maturity of the Debentures
so called for redemption, and unless all of the Debentures or all of the
Debentures of a series or all of the Debentures of one Stated Maturity so
designated for the time being outstanding are to be redeemed, state the
designating numbers of the Debentures so called for redemption and in case a
Debenture is to be redeemed in part only that part of the principal amount
thereof so to be redeemed, and shall specify the redemption date, the
redemption price and the place or places of payment and shall state that all
interest thereon shall cease from and after the said date.

3.3      DEBENTURES DUE ON REDEMPTION DATES

Notice having been given as aforesaid, all the Debentures so called for
redemption shall thereupon become due and payable at the redemption price, on
the redemption date specified in such notice, at any of the places where the
principal of such Debentures is expressed to be payable in the same manner
and with the same effect as if it were the Stated Maturity specified in such
Debentures respectively, anything therein or herein to the contrary
notwithstanding, and from and after such redemption date, if the moneys
necessary to redeem such Debentures shall have been deposited as provided in
section 3.4 and the Trustee shall have been furnished with affidavits or
other proof satisfactory to it as to the publication and/or mailing of such
notices, interest on the said Debentures shall cease and Coupons for interest
to accrue after such redemption date on said Debentures shall become and be
void.

In case any question shall arise whether any notice has been given as above
provided and such deposit made, such question shall be decided by the Trustee
whose decision shall be final and binding upon all parties in interest.

                                     - 16 -

3.4      DEPOSIT OF REDEMPTION MONIES

Such redemption shall be provided for by the Corporation irrevocably
depositing with the Trustee or any Paying Agent to the order of the Trustee
in trust for the Holders of the Debentures called for redemption, before the
redemption date specified in such notice, such sums as may be sufficient to
pay the redemption price of such Debentures including accrued interest and
premium, if any, on the Debentures so called for redemption to the date fixed
for redemption. The Corporation shall also deposit with the Trustee if
required by it a sum sufficient to pay any charges or expenses which may be
incurred by the Trustee in connection with such redemption. From the sums so
deposited the Trustee shall pay or cause to be paid to the Holders of such
Debentures so called for redemption, upon surrender of such Debentures with
all unmatured Coupons, if any, appertaining thereto (or without such
surrender if the registered Holder of the Debentures to be redeemed or the
person for whom such registered Holder is acting as nominee has entered into
an agreement with the Corporation to that effect) the principal, interest and
premium, if any, to which they are respectively entitled on redemption.
Provided that in the case of Bearer Debentures the accrued interest as
represented by Coupons matured prior to, or on, the redemption date shall
continue to be payable (but without interest thereon, unless the Corporation
shall make default in the payment thereof upon demand) to the respective
bearers of such Coupons upon presentation and surrender thereof.

3.5      CANCELLATION AND DESTRUCTION OF DEBENTURES AND COUPONS

All Debentures surrendered for cancellation upon any redemption under this
Article, together with the unmatured Coupons, if any, thereto appertaining,
shall forthwith be delivered to the Trustee and shall be cancelled by it and
no Debentures shall be issued in substitution therefor.

All Debentures and Coupons which shall have been delivered to and cancelled
by the Trustee shall be destroyed by the Trustee and if required by the
Corporation the Trustee shall furnish to it a destruction certificate setting
out the designating numbers and denominations of the Debentures so destroyed.

3.6      SURRENDER OF DEBENTURES FOR CANCELLATION

If the principal moneys of Debentures issued hereunder shall become payable
by redemption or otherwise before the Stated Maturity thereof, the person
presenting such Debenture for payment must surrender the same for
cancellation together with all unmatured Coupons, if any, appertaining
thereto, the Corporation nevertheless paying the interest accrued and unpaid
thereon if the date fixed for payment be not an Interest Payment Date.

3.7      PURCHASE OF DEBENTURES FOR CANCELLATION

At any time when the Corporation is not in default hereunder it may purchase
all or any of the Debentures in the market (which shall include purchase from
or through an investment dealer or a firm holding membership on a recognized
stock exchange) or by invitation for tenders or by private contract and, in
each case, at any price. All Debentures so purchased, together with the
unmatured Coupons (if any) appertaining thereto, shall forthwith be delivered
to the Trustee and shall be cancelled by it and, except as hereinafter
provided, no Debentures shall be issued in substitution therefor.

If and upon an invitation for tenders, more Debentures are tendered at the
same lowest price that the Corporation is prepared to accept, the Debentures
to be purchased by the Corporation shall be selected by the Trustee by lot,
or in such other manner as the Trustee may consider equitable, from the
Debentures tendered by each Debentureholder who tendered at such lowest
price. For this purpose the Trustee may make, and from time to time amend,
regulations with respect to the manner in which Debentures may be so selected
and regulations so made shall be valid and binding upon all Debentureholders,
notwithstanding the fact that, as a result thereof, one or more of such
Debentures become subject to purchase in part only. The Holder of any
Debenture of which a part only is purchased, upon surrender of such Debenture
for payment, shall be entitled to receive, without expense to such Holder,
one or more new Debentures for

<PAGE>

                                     - 17 -

the unpurchased part so surrendered and the Trustee shall certify and deliver
such new Debenture or Debentures upon receipt of the Debenture so surrendered.

                                   ARTICLE 4
                   CONVERSION OF THE CONVERTIBLE DEBENTURES

4.1      CONVERSION PRIVILEGES AND CONVERSION PRICES

The Holders of any Debentures shall have the right, at the holder's option,
to convert such Debentures into Common Shares at such times, at such rates
and on such terms and conditions as shall have been determined at the time of
the issue of such Debentures and as shall be expressed in this Indenture
and/or in the Debentures and/or in the supplemental indenture authorizing or
providing for the issue thereof.

Such right of conversion shall extend only to the maximum number of whole
Common Shares into which the aggregate principal amount of the Convertible
Debenture surrendered for conversion at any one time by the holder thereof
may be converted in accordance with the foregoing provisions of this
subsection and Article 4 hereof. Fractional interests in Common Shares shall
be adjusted for in the manner provided in section 4.4.

4.2      REVIVAL OF RIGHT TO CONVERT

If payment of the purchase price or the redemption price of any Convertible
Debenture which has been tendered in acceptance of an offer by the
Corporation to purchase Convertible Debentures for cancellation or called for
redemption is not made, in the case of a purchase on the date on which such
purchase is required to be made or, in the case of a redemption on the date
when the due surrender of a Convertible Debenture is required to be made, the
right to convert such Convertible Debenture shall revive and continue as if
such Convertible Debenture had not been tendered in acceptance of the
Corporation's offer or called for redemption as the case may be.

4.3      ADJUSTMENT OF CONVERSION PRICE

The Conversion Price for any Convertible Debenture in effect at any date
shall be subject to adjustment from time to time as follows:

         (a)  If and whenever at any time prior to the Time of Expiry
              specified for the series of Convertible Debentures the
              Corporation shall (i) subdivide or redivide the outstanding
              Common Shares into a greater number of shares, (ii) reduce,
              combine or consolidate the outstanding Common Shares into a
              smaller number of shares, or (iii) issue Common Shares or other
              securities convertible into or exchangeable for Common Shares
              to the holders of all or substantially all of the outstanding
              Common Shares by way of a stock dividend (other than the issue
              of Common Shares to holders of Common Shares pursuant to their
              exercise of options to receive dividends in the form of Common
              Shares in lieu of dividends paid in the ordinary course on the
              Common Shares), the 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
              Shares by way of a stock dividend, as the case may be, shall be
              adjusted by multiplying the Conversion Price then in effect by
              a fraction the numerator of which is the number of Common
              Shares 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 Shares 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 Common
              Shares under subsections (c) and (d) of this section 4.3.

         (b)  If and whenever at any time prior to the Time of Expiry
              specified for the series of the Convertible Debentures the
              outstanding Common Shares are reclassified into different
              shares any holder of a Convertible Debenture who has not
              exercised his right of conversion prior to the effective date of

<PAGE>

                                     - 18 -

              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 Common Shares to which he was theretofore entitled
              upon conversion, the aggregate number of shares of the
              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 registered holder of
              the number of Common Shares 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 4.3 and in section 4.4.

         (c)  If and whenever at any time prior to the Time of Expiry
              specified for the series of Convertible Debentures 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 Shares entitling them, for a period expiring
              not more than 45 days after such record date, to subscribe for
              or purchase Common Shares (or securities exchangeable for or
              convertible into Common Shares) at a price per share (or having
              a conversion or exchange price per share) less than 95% of the
              then Current Market Price of a Common Shares on such record
              date, the Conversion Price shall be adjusted immediately after
              such record date so that it shall equal the price determined by
              multiplying the Conversion Price in effect on such record date
              by a fraction, of which the numerator shall be the total number
              of Common Shares outstanding on such record date plus a number
              of Common Shares equal to the number of additional Common
              Shares offered for subscription or purchase (or the aggregate
              conversion or exchange price of the convertible securities so
              offered) by such Current Market Price per Common Shares, and of
              which the denominator shall be the total number of Common
              Shares outstanding on such record date plus the total number of
              additional Common Shares offered for subscription or purchase
              (or into which the convertible securities so offered are
              convertible); any Common Shares 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
              adjustment 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 Conversion Price
              shall be readjusted to the Conversion Price which would then be
              in effect if such record date had not been fixed or to the
              Conversion Price which would then be in effect based upon the
              number of Common Shares (or securities convertible into Common
              Shares) actually issued upon the exercise of such rights or
              warrants, as the case may be, provided that this subsection (c)
              of section 4.3 will not apply to adjust the Conversion Price if
              each holder of a Convertible Debenture is permitted to
              participate in the receipt and exercise of such rights or
              warrants as though such holder had converted the whole of his
              Convertible Debenture in accordance with this Article 4 prior
              to such record date.

         (d)  If and whenever at any time prior to the Time of Expiry
              specified for the series of Convertible Debentures the
              Corporation shall fix a record date for the making of a
              distribution to all or substantially all the holders of its
              outstanding Common Shares of (i) shares of any class other than
              Common Shares and other than shares distributed to holders of
              Common Shares 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 Shares and other than
              shares issued upon any subdivision of Common Shares referred to
              in subsection (a) of this section 4.3 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) then, in each such case,
              the Conversion Price shall be adjusted immediately after such
              record date so that it shall equal the price determined by
              multiplying the Conversion Price in effect on such record date
              by a fraction, of which the numerator shall be the total number
              of Common Shares outstanding on such record date multiplied by
              the Current Market Price for such Shares, 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 Common Shares
              outstanding on such record date multiplied by such Current
              Market Price

<PAGE>

                                     - 19 -

              per Common Share; any Common Shares 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 Conversion Price shall be readjusted to the
              Conversion Price which would then be in effect if such record
              date had not been fixed or the Conversion Rate 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 4.3
              will not apply to adjust the Conversion Price if each holder of
              a Convertible Debenture is permitted to participate in such
              Distribution as though such holder had converted the whole of
              his Convertible Debenture in accordance with this Article 4
              prior to such record date.

         (e)  In case of any reclassification of, or any other material
              change in, the outstanding Common Shares of the Corporation
              other than a subdivision, redivision, reduction, combination or
              consolidation, the Conversion Price shall be adjusted in such
              manner as the board of directors, with the approval of the
              Trustee, determines to be appropriate on a basis consistent
              with this section 4.3.

         (f)  If and whenever at any time prior to the Time of Expiry
              specified for the series of Convertible Debentures, there is a
              capital reorganization of the Corporation not covered by the
              foregoing provisions of this section 4.3 or a consolidation or
              merger or amalgamation of the Corporation with or into any
              other company including by way of a sale whereby all or
              substantially all of the Corporation's undertaking and assets
              would become the property of any other company, and holder of a
              Convertible Debenture 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 accept, upon the exercise of such right at
              any time on such effective date or thereafter, in lieu of the
              number of Common Shares to which he was theretofore entitled
              upon conversion, the aggregate number of shares or other
              securities or 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 Common Shares 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 4.3 and in
              section 4.4.

         (g)  In any case in which this section 4.3 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 occurrence of such event, issuing to the holder of
              any Convertible Debenture converted after such record date and
              before the occurrence of such event the additional Common
              Shares 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 Common Shares
              upon the occurrence of the event requiring such adjustment and
              the right to receive any distributions made on such additional
              Common Shares declared in favour of holders of record of Common
              Shares 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 Common
              Shares.

         (h)  The adjustments provided for in this section 4.3 and in section
              4.4 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 Conversion

<PAGE>

                                     - 20 -

              Price shall be required unless such adjustment would require an
              increase or decrease of at least 1% in the 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.

         (i)  In the event of any question arising with respect to the
              adjustments provided in this section 4.3, such question shall
              be conclusively determined by a firm of chartered accountants
              appointed by the Corporation and acceptable to the Trustee (who
              may be the auditors of the Corporation); such accountants shall
              have access to all necessary records of the Corporation and
              such determination shall be binding upon the Corporation, the
              Trustee and the Debentureholders.

4.4      NO REQUIREMENT TO ISSUE FRACTIONAL SHARES

The Corporation shall not be required to issue fractional Common Shares upon the
conversion of Convertible Debentures pursuant to this Article. If more than one
Convertible Debenture shall be surrendered for conversion at one time by the
same holder, the number of whole Common Shares issuable upon conversion thereof
shall be computed on the basis of the aggregate principal amount of such
Convertible Debentures to be converted. If any fractional interest in a Common
Share would, except for the provisions of this section, be deliverable upon the
conversion of any principal amount of Convertible Debentures the Corporation
shall, in lieu of delivering any certificate of such fractional interest,
satisfy such fractional interest by paying to the holder of such surrendered
Convertible Debenture an amount in lawful money of Canada equal (computed to the
nearest cent) to the appropriate fraction of the value (being the last reported
sale price or, if none, the mean between the closing bid and ask quotations on
The Vancouver Stock Exchange, on such stock exchange on which the Common Shares
are listed, as may be selected for such purpose by the Directors of, if the
Common Shares are not listed on any stock exchange, a value determined by the
Directors and approved by the Trustee) of a Common Share on the business day
next preceding the Date of Conversion.

4.5      CORPORATION TO RESERVE SHARES

The Corporation covenants with the Trustee that it will at all times reserve and
keep available out of its authorized Common Shares, solely for the purpose of
issue upon conversion of Convertible Debentures as in this Article provided, and
conditionally allot to Debentureholders who may exercise their conversion rights
hereunder, such number of Common Shares as shall then be issuable upon the
conversion of all outstanding Convertible Debentures. The Corporation covenants
with the Trustee that all Common Shares which shall be so issuable shall be duly
and validly issued as fully-paid and non-assessable.

4.6      TAXES AND CHARGES ON CONVERSION

The Corporation will from time to time promptly pay or make provision
satisfactory to the Trustee for the payment of any and all taxes and charges
which may be imposed by the laws of Canada or any province thereof (except
income tax, withholding tax, security transfer tax, if any, or taxes or levies
which are in substance of the same nature as any of the foregoing) which shall
be payable with respect to the issuance and/or delivery to the holders of
Convertible Debentures, upon the exercise of their right to conversion, of
Common Shares of the Corporation pursuant to the terms of the Convertible
Debentures and of this Indenture.

4.7      CANCELLATION OF CONVERTED DEBENTURES

All Convertible Debentures converted in whole or in part under the provisions of
this Article shall be forthwith delivered to and cancelled by the Trustee and,
subject to the provisions of any particular Debentures, no Debenture shall be
issued in substitution therefor.

4.8      CERTIFICATE AS TO ADJUSTMENT

The Corporation shall from time to time immediately after the occurrence of any
event which requires an adjustment or readjustment as provided in section 4.3,
deliver an Officers' Certificate to the Trustee and, where specified with
respect to any series of Convertible Debentures, each Paying Agent and
Conversion Agent specifying the nature of the event requiring the same and the
amount of the adjustment necessitated thereby and setting forth in reasonable
detail the method of calculation and the facts upon which such calculation is
based, which certificate and the amount of the adjustment specified therein
shall be verified by an opinion of a firm of chartered accountants appointed by
the Corporation and acceptable to the Trustee (who may be the auditors of the
Corporation) and, when approved by the Trustee, shall be conclusive and binding
on all parties in interest. When so approved, the Corporation shall, except in
respect of any subdivision, redivision, reduction, combination or consolidation
of the Common Shares, forthwith give notice to the holders of Convertible
Debentures in the manner provided in section 10.2 specifying the event requiring
such adjustment or readjustment and the results thereof, including the resulting
Conversion Price of the series of Convertible Debentures of which the holder is
registered; provided that, if the Corporation has given notice under section 4.9
covering all the relevant facts in respect of such event, no such notice need be
given under this section 4.8.

4.9      NOTICE OF SPECIAL MATTERS

The Corporation covenants with the Trustee that so long as any Convertible
Debenture remains outstanding, it will give notice in the manner provided in
section 10.3 to the Trustee, and to the holders of Convertible Debentures of its
intention to fix a record date or an effective date for any event referred to in
subsections (a), (b), (c), (d) or (f) of section 4.3 (other than the
subdivision, redivision, reduction, combination or consolidation of its Common
Shares) which may give rise to an adjustment in the Conversion Price, and, in
each case, such notice shall specify the particular of such event; provided that
the Corporation shall only be required to specify in such notice such
particulars of such event as shall have been fixed and determined on the date on
which such notice is given. Such notice shall be given not less than 10 days in
each case prior to such applicable record date or effective date.

4.10     PROTECTION OF TRUSTEE

Subject to section 11.7, the Trustee (i) shall not at any time be under any duty
or responsibility to any holder of a Convertible Debenture to determine whether
any facts exist which may require any adjustment in the Conversion Price, or
with respect to the nature or extent of any such adjustment when made, or with
respect to the method employed in making the same; (ii) shall not be accountable
with respect to the validity or value (or kind or amount) of any Common Shares
or of any shares or other securities or property which may at any time be issued
or delivered upon the conversion of any Convertible Debenture; or (iii) shall
not be responsible for any failure of the Corporation to make any cash payment
or to issue, transfer or deliver Common Shares or share certificates upon the
surrender of any Convertible Debenture for the purpose of conversion, or to
comply with any of the covenants contained in this Article.

5.2      MAINTENANCE OF CORPORATE EXISTENCE

Except as herein otherwise expressly provided, the Corporation will at all times
maintain, preserve and keep in full force and effect its corporate existence,
rights (charter and statutory) and franchises and the Corporation will carry on
and conduct or will cause to be carried on and conducted its business and the
business of its Subsidiaries in a proper and efficient manner and will keep or

such agent or attorney.

The Corporation will furnish to the Trustee a copy of all financial statements,
whether annual or interim, of the Corporation and the report, if any, of the

expenditure until repayment, and such moneys and the interest thereon, including
the Trustee's remuneration, shall be payable out of any funds coming into the
possession of the Trustee in priority to any of the Debentures or interest
thereon. The said remuneration shall continue to be payable until the trusts
hereof be finally wound up and whether or not the trusts of this Indenture shall
be in the course of administration by or under the direction of the court.

5.5      MAINTENANCE OF OFFICE OR AGENCY

If the Debentures of a series are issuable only as Registered Debentures, the
Corporation will maintain in each Place of Payment for such Debentures an office
or agency where Debentures of that series may be presented or surrendered for
payment, where Debentures of that series may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Corporation in
respect of the Debentures of that series and this Indenture may be served.

If Debentures of a series are issuable as Bearer Debentures, the Corporation
will maintain:

         (a)  in the city of Calgary, an office or agency where any
              Registered Debentures of that series may be presented or
              surrendered for payment, where any Registered Debentures of
              that series may be surrendered for registration of transfer,
              where Debentures of that series may be surrendered for
              exchange, where notices and demands to or upon the Corporation
              in respect of the Debentures of that series and this Indenture
              may be served and where Bearer Debentures of that series and
              related Coupons may be presented or surrendered for payment in
              the circumstances described in the following paragraph (and not
              otherwise);

         (b)  subject to any laws or regulations applicable thereto, in a
              Place of Payment for that series which is located outside
              Canada, an office or agency where Debentures of that series and
              related Coupons may be presented or surrendered for payment;
              provided, however, that, if the Debentures of that series

<PAGE>

                                     - 24 -

              are listed on any stock exchange located outside Canada and
              such stock exchange shall so require, the Corporation will
              maintain a Paying Agent for the Debentures of that series in
              any required city located outside Canada so long as the
              Debentures of that series are listed on such exchange; and

         (c)  subject to any laws or regulations applicable thereto, in a
              Place of Payment for that series located outside Canada, an
              office or agency where any Registered Debentures of that series
              may be surrendered for registration of transfer, where
              Debentures of that series may be surrendered for exchange and
              where notices and demands to or upon the Corporation in respect
              of the Debentures of that series and this Indenture may be
              served. The Corporation will give prompt written notice to the
              Trustee of the location, and any change in the location, of
              such office or agency. If at any time the Corporation shall
              fail to maintain any such required office or agency or shall
              fail to furnish the Trustee with the address thereof, such
              presentations, surrenders, notices and demands may be made or
              served at the principal office of the Trustee in the city of
              Calgary, except that Bearer Debentures of that series and the
              related Coupons may be presented and surrendered for payment at
              the offices specified in the Debenture, and the Corporation
              hereby appoints the same as its agent to receive such
              respective presentations, surrenders, notices and demands.

The Corporation may also from time to time designate one or more other offices
or agencies where the Debentures of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Corporation of its obligation to maintain an office or
agency in accordance with the requirements set forth above for Debentures of any
series for such purposes. The Corporation will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location
of any such other office or agency. Unless otherwise specified with respect to
any Debentures as contemplated by section 2.2 with respect to a series of
Debentures, the Corporation hereby designates as a Place of Payment for each
series of Debentures the principal office of the Trustee in the city of Calgary,
and initially appoints the Trustee at its principal office as Paying Agent in
such city and as its agent to receive all such presentations, surrenders,
notices and demands.

5.6      MONEY FOR DEBENTURES PAYMENTS TO BE HELD IN TRUST

If the Corporation shall at any time act as its own Paying Agent with respect to
any series of Debentures and any related Coupons, it will, on or before each due
date of the principal of (and premium, if any) or interest on any of the
Debentures of that series, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum in the currency in which the Debentures of such
series are payable (except as otherwise specified pursuant to section 2.2 for
the Debentures of such series) sufficient to pay the principal (and premium, if
any) or interest so becoming due until such sums shall be paid to such Persons
or otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure to so act.

Whenever the Corporation shall have one or more Paying Agents for any series of
Debentures and any related Coupons, it will, prior to or on each due date of the
principal of (and premium, if any) or interest on any Debentures of that series,
deposit with a Paying Agent a sum (in the currency described in the preceding
paragraph) sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Corporation will promptly notify the Trustee of its action
or failure to so act.

The Corporation will cause each Paying Agent (other than the Trustee) for any
series of Debentures to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this section, that such Paying Agent will:

         (a)  hold all sums held by it for the payment of the principal of
              (and premium, if any) and interest on securities of such series
              (where such sums have been paid to it by the Corporation or by
              any other

<PAGE>

                                     - 25 -

              obligor on the Debentures) in trust for the benefit of the
              Persons entitled thereto until such sums shall be paid to such
              Persons or otherwise disposed of as herein provided;

         (b)  give the Trustee notice of any default by the Corporation (or
              any other obligor upon the securities of such series) in the
              making of any payment of principal of (or premium, if any) or
              interest on the Debentures of such series; and

         (c)  at any time during the continuance of such default, upon the
              written request of the Trustee, forthwith pay to the Trustee
              all sums so held in trust by such Paying Agent.

The Corporation may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Written
Order of the Corporation direct any Paying Agent to pay, to the Trustee all sums
held in trust by the Corporation or such Paying Agent, such sum to be held by
the Trustee upon the same trusts as those upon which sums were held by the
Corporation or such Paying Agent; and, upon such payment by any Paying Agent to
the Trustee, such Paying Agent shall be released from all further liability with
respect to such sums.

Except as provided in the Debentures of any series, any money deposited with the
Trustee or any Paying Agent, or then held by the Corporation, in trust for the
payment of the principal of (and premium, if any) or interest on any Debenture
of any series and remaining unclaimed for two years after such principal (and
premium, if any) or interest have become due and payable shall be paid to the
Corporation on Written Request of the Corporation, or (if then held by the
Corporation) shall be discharged from such trust; and the Holder of such
Debenture shall thereafter, as an unsecured general creditor, look only to the
Corporation for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Corporation as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the
expense of the Corporation cause to be published once, in an Authorized
Newspaper, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Corporation.

5.7      STATEMENT AS TO COMPLIANCE

The Corporation covenants that, on or before December 31, 1998, and on or before
December 31 in each subsequent year and at any other time if requested by the
Trustee, the Corporation will furnish to the Trustee a Certificate of the
Corporation stating that the Corporation has performed its obligations under and
complied with all covenants, conditions and other requirements contained in this
Indenture, non-compliance with which would, with the giving of notice or the
lapse of time or both, constitute an Event of Default hereunder or, if such is
not the case, specifying the covenant, condition or other requirement which has
not been complied with and giving particulars of such non-compliance and the
action, if any, the Corporation proposes to take with respect thereto. If the
officer signing the Certificate of the Corporation knows of such an Event of
Default, whether then existing or occurring during such preceding fiscal year,
the Certificate of the Corporation shall describe such Event of Default and its
status with particularity. The Corporation shall also promptly notify the
Trustee if the Company's fiscal year is changed so that the end thereof is on
any date other than the then current fiscal year end date. For purposes of this
section, such compliance shall be determined without regard to any period of
grace granted by the Trustee or requirement of notice under this Indenture. The
Corporation will deliver to the Trustee, forthwith upon becoming aware of any
default in the performance or observance of any covenant, agreement or condition
contained in this Indenture, or any Event of Default, a Certificate of the
Corporation specifying with particularity such Event of Default and further
stating what action the Corporation has taken or is taking or proposes to take
with respect thereto.

5.8      ADDITIONAL AMOUNTS

If any Debentures of a series provide for the payment of additional amounts to
any Holder in respect of any tax, assessment or governmental charge ("Additional
Amounts"), the Corporation will pay to the Holder of any Debenture of such
series or any Coupon appertaining thereto such Additional Amounts as may be
specified as contemplated by section 2.2. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest on, or in respect of, any Debenture of a series or payment of any
related Coupon or the net proceeds received on the sale or exchange of any
Debenture of a series, such mention shall be deemed to include mention of the
payment of Additional Amounts provided for by the terms of such series
established pursuant to section 2.2 to the extent that, in such context,
Additional Amounts are, were or would be payable in respect thereof pursuant to
such terms and express mention of the payment of Additional Amounts (if
applicable) in any provisions hereof shall not be construed as excluding
Additional Amounts in those provisions hereof where such express mention is not
made.

Except as otherwise specified as contemplated by section 2.2, if the Debentures
of a series provide for the payment of Additional Amounts, at least 10 days
prior to the first Interest Payment Date with respect to that series of
Debentures (or if the Debentures of that series will not bear interest prior to
Maturity, the first day on which a payment of principal and any premium is
made), and at least 10 days prior to each date of payment of principal and any
premium or interest if there has been any change with respect to the matters set
forth in the below-mentioned Certificate of the Corporation, the Corporation
will furnish the Trustee and the Corporation's principal Paying Agent or Paying
Agents, if other than the Trustee, with a Certificate of the Corporation
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal of and any premium of interest on the Debentures of that
series shall be made to the Holders of Debentures of that series or any related
Coupons without withholding for or on account of any tax, assessment or other
governmental charge described in the Debentures of the series. If any such
withholding shall be required, then such Certificate of the Corporation shall
specify by country the amount, if any, required to be withheld on such payments
to such Holders of Debentures of that series or related Coupons and the
Corporation will pay to the Trustee or such Paying Agent the Additional Amounts
required by the terms of such Debentures. In the event that the Trustee or any
Paying Agent, as the case may be, shall not so receive the above-mentioned
certificate, then the Trustee or such Paying Agent shall be entitled to (i)
assume that no such withholding or deduction is required with respect to any
payment of principal or interest with respect to any Debentures of a series or
related Coupons until it shall have received a certificate advising otherwise
and (ii) to make all payments of principal and interest with respect to the
Debentures of a series or related Coupons without withholding or deductions
until otherwise advised. The Corporation covenants to indemnify the Trustee and
any Paying Agent for, and to hold them harmless against, any loss, liability or
expense reasonably incurred without negligence or bad faith on their part
arising out of or in connection with actions taken or omitted by any of them in
reliance on any Certificate of the Corporation furnished pursuant to this
section.

5.9      LONG TERM DEBT AND TANGIBLE ASSETS

The Corporation will, so long as any Debenture is outstanding, maintain Tangible
Assets equal to or greater than 140% of Long Term Debt at all times including
after redemption of any redeemable preference shares of the Corporation or any
Subsidiary. This ratio shall be calculated no later than the 135th day following
the end of each of the Corporation'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.

                                     - 27 -

                  in an amount not to exceed US$6,000,000 to reduce the EnCap
                  Credit Facility to an amount outstanding of not less than
                  US$12,000,000.

5.11     WAIVER OF CERTAIN COVENANTS

The Corporation may omit in any particular instances to comply with any term,
provision or condition set forth in section 5.10, if the Holders of Debentures
outstanding, by Extraordinary Resolution, waive such compliance in such
instances with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Corporation and the duties of the Trustee in respect of any such term,
provision or condition shall remain in full force and effect.

5.12     PAYMENT OF TAXES AND OTHER CLAIMS

The Corporation will pay or discharge or cause to be paid or discharged, before
the same shall become delinquent, (a) all taxes, assessments and governmental
charges levied or imposed upon the Corporation or any Subsidiary or upon the
income, profits or property of the Corporation or any Subsidiary and (b) all
lawful claims for labour, materials and supplies which, if unpaid, might by law
become a Lien upon the property of the Corporation or any Subsidiary; PROVIDED,
HOWEVER, that the Corporation shall not be required to pay or discharge or cause
to be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

The Corporation will cause all properties owned by the Corporation or any
Subsidiary or used or held for use in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order (ordinary wear and tear excepted) and supplied with all
necessary equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Corporation may be necessary so that the business carried on in connection
therewith may be conducted at all times; PROVIDED, HOWEVER, that nothing in this
section shall prevent the Corporation from discontinuing the maintenance of any
of such properties if such discontinuance is, in the judgment of the
Corporation, desirable in the conduct of its business or the business of any
Subsidiary and not disadvantageous in any material respect to the
Debentureholders.

5.14     INSURANCE

The Corporation will at all times keep all of the Corporation's and its
Subsidiaries' properties which are of an insurable nature insured with insurers,
believed by the Corporation to be responsible, against loss or damage to the
extent that property of similar character is usually so insured by corporations
similarly situated and owning like properties in similar geographic areas in
which the Corporation or each such Subsidiary operates; provided that such
insurance is generally available at commercially reasonable rates, and provided
further that the Corporation or such Subsidiary may self-insure directly or
through captive insurers or insurance cooperatives, to the extent that the
Corporation determines that such practice is consistent with prudent business
practices. Such insurance shall be in such amount, on such terms, in such forms
and for such periods as are customary for similarly situated Persons in the
Corporation's industry or in insurance markets available to the Corporation.

5.15     RESTRICTIONS ON CHARTER AMENDMENTS

The Corporation will not amend its Memorandum and Articles of Association except
as required by law or except to the extent that such amendment would not have a
material adverse effect on (a) the ability of the Corporation to perform its
obligations under this Indenture or the Debentures or (b) the rights of the
Debenture Holders, except that neither (i) increases in the number of common
shares and issuance thereof with related securities, nor (ii) designations of
preferred stock of the Company, modifications of the terms of such designations
and issuance thereof with related


<PAGE>

securities, nor (iii) modification or expansion of the indemnity provisions
provided by the Corporation to its directors and officers, nor (iv) change of
the Corporation's registered agent shall be deemed an amendment hereunder.

5.16     CANADIAN WITHHOLDING AND REPORTING REQUIREMENTS

To the extent permitted by law, the Corporation will provide to the Trustee, the
Paying Agent or to any Debenture Holder such statements, certificates or other
documentation concerning the organization or operations of the Corporation as
may be reasonably necessary to establish any exceptions or exemptions from
Canadian federal income tax withholding and reporting requirements.

5.17     MAINTENANCE OF LISTINGS FOR COMMON SHARES AND DEBENTURES

While any Convertible Debenture remains outstanding, the Corporation will
maintain a listing for its common shares on a nationally recognized stock
exchange in Canada or the United States and, while any Convertible Debenture
Series 1 is outstanding, will use its best efforts to maintain a listing for the
Convertible Debentures Series 1 on the Luxembourg Stock Exchange or such
alternative stock exchange as the Trustee may approve.

5.18     TRUSTEE MAY PERFORM COVENANTS

If the Corporation shall fail to perform any of its covenants contained herein,
the Trustee may in its discretion, but (subject to section 6.3) need not, notify
the Debentureholders of such failure or may itself perform any of such covenants
capable of being performed by it and, if any such covenant requires the payment
of money, it may make such payment with its own funds, or with money borrowed by
it for such purpose, but shall be under no obligation to perform such covenants
or to make any such payments with its own funds or with money borrowed by it;
and all sums so paid shall be payable by the Corporation in accordance with the
provisions of section 5.4. No such performance by the Trustee of any covenant
contained herein or payment by the Corporation of any sums advanced or borrowed
by the Trustee pursuant to the foregoing provisions shall be deemed to relieve
the Corporation from any default hereunder.

                  Material Subsidiary fails to pay when due (or, as the case may
                  be, within any applicable grace period) any amount payable by
                  it under any present or future guarantee for, or indemnity in
                  respect of, any Indebtedness of any Person or (iv) any
                  security given by the Corporation or any Material Subsidiary

                  indemnity of Debt of any Person by the Corporation or any
                  Material Subsidiary becomes enforceable by reason of default
                  in relation thereto and steps are taken to enforce such
                  security save in any such case where there is a bona fide
                  dispute as to whether the relevant Debt or any such guarantee
                  or indemnity as aforesaid shall be due and payable (following
                  any applicable grace period), PROVIDED that in each such case
                  the Debt exceeds in the aggregate US$1,500,000 and in each
                  such case such event continues unremedied for a period of 30
                  calendar days (or such longer period as the Trustee may in its
                  sole discretion consent to in writing upon receipt of written
                  notice from the Company); or

         (g)      if there is any final judgment or judgments for the payment of
                  money exceeding in the aggregate U.S.$1,5000,000 outstanding
                  against the Corporation or any Material Subsidiary which has
                  been outstanding for more than 60 calendar days from the date
                  of its entry and shall not have otherwise been discharged in
                  full or stayed by appeal, bond or otherwise; or

         (h)      if the Issuer or any Material Subsidiary shall generally fail
                  to pay its Debts as such Debts come due (except Debts which
                  the Issuer or such Material Subsidiary, as the case may be,
                  may contest in good faith generally) or shall be declared or

                  documents is false in any material respect when made and
                  (except where the Trustee shall have certified to the Issuer
                  that it considers such falsity to be incapable of remedy, in
                  which case no such notice or continuation as is hereinafter
                  mentioned will be required) such falsity continues for a
                  period of 30 calendar days (or such longer period as the
                  Trustee may in its absolute discretion permit) next following
                  the service by the Trustee on the Issuer of notice requiring
                  the same to be remedied; or

         (j)      any other Event of Default provided with respect to Debentures
                  of that series.

6.2      NOTICE OF EVENTS OF DEFAULT

The Corporation shall, within 30 days after it becomes aware that an Event of
Default has occurred, notify the Trustee of the occurrence of such Event of
Default and upon receipt of such notice and if the Event of Default is
continuing the Trustee shall, within 30 days after it becomes aware of the
occurrence of such Event of Default, give notice thereof to the
Debentureholders, provided that, notwithstanding the foregoing, the Trustee
shall not be required to give such notice if the Trustee in good faith shall
have decided that the withholding of such notice is in the best interests of the
Debentureholders and shall have so advised the Corporation in writing. Where
notice of the occurrence of an Event of Default has been given and the Event of
Default is thereafter cured, notice that the Event of Default is no longer
continuing shall be given by the Trustee to the Debentureholders within 30 days
after the Trustee becomes aware that the Event of Default has been cured.

6.3      ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT

If an Event of Default described in clause (a), (b) or (j) of section 6.1 with
respect to Debentures of any series at the time outstanding occurs and is
continuing, then in every such case the Trustee or the Holders of not less than
25% in principal amount of the outstanding Debentures of that series may declare
the principal amount of all the Debentures of that series to be due and payable
immediately, by a notice in writing to the Corporation (and to the Trustee if
given by Holders), and upon any such declaration such principal amount (or
specified portion thereof) shall become immediately due and payable. If an Event
of Default described in clause (c), (d), (e), (f), (g), (h) or (i) of section
6.1 occurs and is continuing, then in every such case the Trustee or the Holders
of not less than 25% in principal amount of all the Debentures then outstanding
may declare the principal amount of all the outstanding Debentures to be due and
payable immediately, by a notice in writing to the Corporation (and to the
Trustee if given by the Holders) and upon any such declaration such principal
amount (or specified portion thereof) shall become immediately due and payable.

At any time after such a declaration of acceleration with respect to Debentures
of any series (or of all series, as the case may be) has been made and before a
judgment or decree for payment of the money due has been obtained by the Trustee
as hereinafter in this Article provided, the Holders of the outstanding
Debentures of that series (or of all series, as the case may be), by
Extraordinary Resolution, may rescind and annul such declaration and its
consequences if:

         (a)      the Corporation has paid or deposited with the Trustee a sum
                  sufficient to pay in the currency in which the Debentures of
                  such series are payable (except as otherwise specified
                  pursuant to section 2.2 for the Debentures of such series):

                  (i)      all overdue interest on all outstanding Debentures of
                           that series (or  of all series, as the case may be)
                           and any related Coupons,

                  (ii)     all unpaid principal of (and premium, if any, on) any
                           outstanding Debentures of that series (or of all
                           series, as the case may be) which has become due
                           otherwise than by such declaration of acceleration,
                           and interest on such unpaid principal at the rate or
                           rates prescribed therefor in such Debentures,



<PAGE>


                                     - 31 -

                  (iii)    interest upon overdue interest at the rate or rates
                           prescribed therefor in such Debentures, and

                  (iv)     all sums paid or advanced by the Trustee hereunder
                           and the reasonable compensation, expenses,
                           disbursements and advances of the Trustee, its agents
                           and counsel and any sales, value-added or goods and
                           services tax thereon; and

         (b)      all Events of Default with respect to Debentures of that
                  series (or of all series, as the case may be), other than the
                  non-payment of amounts of principal of (or premium, if any) or
                  interest on Debentures of that series (or of all series, as
                  the case may be) which have become due solely by such
                  declaration of acceleration, have been cured or waived as
                  provided in section 6.14.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

6.4      COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE

The Corporation covenants that if:

         (a)      default is made in the payment of any instalment of interest
                  on any Debenture and any related Coupon when such interest
                  becomes due and payable and such default continues for a
                  period of 30 days or

         (b)      default is made in the payment of the principal of (or
                  premium, if any, on) any Debenture at the Maturity thereof,

then the Corporation will, upon demand of the Trustee, pay to the Trustee for
the benefit of the Holders of such Debentures and Coupons the whole amount then
due and payable on such Debentures and Coupons for principal (and premium, if
any) and interest on any overdue principal (and premium, if any) and on any
overdue interest, at the rate or rates prescribed therefor in such Debentures,
and, in addition thereto, such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Corporation fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Corporation or any other obligor upon such Debentures and collect
the moneys adjudged or decreed to be payable in the manner provided by law out
of the property of the Corporation or any other obligor upon such Debentures,
wherever situated.

If an Event of Default with respect to Debentures of any series (or of all
series, as the case may be) occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders of Debentures of such series (or of all series, as the case may be) by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

6.5      TRUSTEE MAY FILE PROOFS OF CLAIM

In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustments, composition or other
judicial proceeding relative to the Corporation or any other obligor upon the
Debentures or the property of the Corporation or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Debentures
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Corporation for the payment


<PAGE>


                                     - 32 -

of overdue principal, premium, if any or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise,

         (a)      to file and prove a claim for the whole amount of principal
                  (and premium, if any) and interest owing and unpaid in respect
                  of the Debentures and to file such other papers or documents
                  as may be necessary or advisable in order to have the claims
                  of the Trustee (including any claim for the reasonable
                  compensation, expenses, disbursements and advances of the
                  Trustee, its agents and counsel and any sales, value added or
                  goods and services tax thereon) and of the Holders allowed in
                  such judicial proceedings; and

         (b)      to collect and receive any moneys or other property payable or
                  deliverable on any such claim and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under section 5.4.

Nothing herein contained shall be deemed to authorize the Trustee to authorize

Coupons may be prosecuted and enforced by the Trustee without the possession of

relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel and
any sales, value-added or goods and services tax thereon, be for the rateable
benefit of the Holders of the Debentures and Coupons in respect of which such

No Holder of any Debenture of any series or any related Coupons shall have any
right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless

         (a)      such Holder has previously given written notice to the Trustee
                  of a continuing Event of Default with respect to the
                  Debentures of that series;

         (b)      the Holders of not less than 25% in principal amount of the

                  Trustee to institute proceedings in respect of such Event of
                  Default in its own name as Trustee hereunder;

         (c)      such Holder or Holders have offered to the Trustee reasonable
                  indemnity against the costs, expenses and liabilities to be
                  incurred in compliance with such request;

         (d)      the Trustee for 60 days after its receipt of such notice,
                  request and offer of indemnity has failed to institute any
                  such proceeding, and

         (e)      no direction inconsistent with such written request has been
                  given, by Extraordinary Resolution, to the Trustee during such
                  60 day period by the Holders of the outstanding Debentures of
                  that series in the case of any Event of Default described in

                  (h) or (i) of section 6.1, by the Holders of all outstanding
                  Debentures;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of Debentures of the same series, in the case of any Event of Default
described in clause (a), (b) or (j) of section 6.1 or of Holders of all
Debentures in the case of an Event of Default described in clause (c), (d), (e),
(f), (g), (h) or (i) of section 6.1, or to obtain or to seek to obtain priority
or preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and rateable
benefit of all Holders of Debentures of the same series, in the case of any
Event of Default described in clause (a), (b) or (j) of section 6.1, or of
Holders of all Debentures in the case of any Event of Default described in
clause (c), (d), (e), (f), (g), (h) or (i) of section 6.1.

6.9      RESTORATION OF RIGHTS AND REMEDIES

If the Trustee or any Holder has instituted any proceeding to enforce any right
or remedy under this Indenture and such proceeding has been discontinued or
abandoned for any reason, or has been determined adversely to the Trustee or to
such Holder, then and in every such case, subject to any determination in such

6.10     RIGHTS AND REMEDIES CUMULATIVE

No right or remedy herein conferred upon or reserved to the Trustee or to the
Holders of Debentures or Coupons is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in additional to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

6.11     DELAY OR OMISSION NOT WAIVER

No delay or omission of the Trustee or of any Holder of any Debentures or
Coupons to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this
Indenture or by law to the Trustee or to the Holders may be exercised from time
to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be.

6.12     CONTROL BY HOLDERS

With respect to the Debentures of any series, the Holders of the outstanding
Debentures of such series shall have the right, by Extraordinary Resolution, to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred on the
Trustee relating to or arising under clause (a), (b) or (j) of section 6.1, and,
with respect to all Debentures, the Holders of all outstanding Debentures shall
have the right to direct, by Extraordinary Resolution, the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee, or exercising any trust
or power conferred on the Trustee, not relating to or arising under clause (a),
(b) or (j) of section 6.1, provided that in each case:

         (a)      such direction shall not be in conflict with any rule of law
                  or with this Indenture,

         (b)      the Trustee may take any other action deemed proper by the
                  Trustee which is not inconsistent with such direction, and

         (c)      the Trustee need not take any action which might involve it in
                  personal liability or be unjustly prejudicial to the Holders
                  of Debentures of such series not consenting.

6.13     WAIVER OF PAST DEFAULTS

Subject to section 6.3, the Holders of the outstanding Debentures of any series
may on behalf of the Holders of all the Debentures of such series, by
Extraordinary Resolution, waive any past default described in clause (a), (b) or
(j) of section 6.1 (or, in the case of a default described in clause (c), (d),
(e), (f), (g), (h) or (i) of section 6.1, the Holders of all outstanding
Debentures may, by Extraordinary Resolution, waive any such past default), and
its consequences, except a default:

         (a)      in respect of the payment of the principal of (or premium, if
                  any) or interest of any Debenture or any related Coupon, or

         (b)      in respect of a covenant or provision hereof which under
                  Article 12 cannot be modified or amended without the consent
                  of the Holder of each outstanding Debenture of such series
                  affected.

Upon any such waiver, any such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or Event of Default or impair any right consequent thereon.

6.14     WAIVER OF STAY OR EXTENSION

The Corporation covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Corporation (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                          SATISFACTION AND DISCHARGE

7.1      CANCELLATION AND DESTRUCTION

All matured Debentures and Coupons shall forthwith after payment thereof be
delivered to the Trustee and cancelled by it. All Debentures and Coupons which
are cancelled or required to be cancelled under this or any other provision of

Corporation, the Trustee shall furnish to the Corporation a destruction
certificate setting out the designating numbers and denominations of the
Debentures and Coupons so destroyed.

7.2      NON-PRESENTATION OF DEBENTURES AND COUPONS

If the Holder of any Debenture or Coupon shall fail to present the same for
payment on the date on which the principal thereof and/or the interest thereon
or represented thereby becomes payable either at Maturity or otherwise or shall
not accept payment on account thereof and give such receipt therefor (if any) as
the Trustee may require:

         (a)      the Corporation shall be entitled to pay to the Trustee and
                  direct it to set aside; or

         (b)      in respect of moneys in the hands of the Trustee which may or
                  should be applied to the payment of the Debentures, the
                  Corporation shall be entitled to direct the Trustee to set
                  aside;

the principal moneys and/or the interest, as the case may be, in trust to be
paid to the Holder of such Debenture or Coupon upon due presentation and
surrender thereof in accordance with the provisions of this Indenture; and
thereupon the principal moneys and/or the interest payable on or represented by
each Debenture and each Coupon in respect whereof such moneys have been set
aside shall be deemed to have been paid and thereafter such Debentures and
Coupons shall not be considered as outstanding hereunder and the Holders thereof
shall thereafter have no right in respect thereof except that of receiving
payment of the moneys so set aside by the Trustee (without interest thereon)
upon due presentation and surrender thereof, subject always to the provisions of
section 5.6 as they relate to the repayment of unclaimed moneys. Any moneys so
set aside may, and, if remaining unclaimed for 60 days shall, be invested by the
Trustee in accordance with section 11.8.

7.3      DEFEASANCE

The Trustee shall, at the request and at the expense of the Corporation, execute
and deliver to the Corporation such deeds or other instruments as shall be
necessary to release the Corporation, subject to section 7.4, from its covenants
contained herein except those relating to the indemnification of the Trustee and
to the maintenance of an office or agency for the Debentures as contemplated by
sections 5.4 and 5.5 upon:

         (a)      proof being given to the reasonable satisfaction of the
                  Trustee that the Corporation has deposited funds or made
                  provision for payment of the expenses of the Trustee, for
                  payment of all principal and interest and other amounts due or
                  to become due on the Debentures (including amounts due or to


<PAGE>


                                     - 36 -

                  become due with respect to any series of Debentures as a
                  result of a provision contemplated by section 2.2) and for the
                  payment of Taxes arising with respect to such deposited funds
                  or other provision for payment (collectively, the "Payments")
                  pursuant to the terms of an irrevocable trust agreement in
                  form and substance satisfactory to the Trustee; and

         (b)      delivery by the Corporation to the Trustee of an opinion of
                  Counsel, which opinion shall be satisfactory to the Trustee in
                  its sole discretion, that the Debentureholders will not be
                  subject to any Taxes as a result of the Corporation's exercise
                  of this defeasance option and that they will be subject to
                  Taxes, including those in respect of income (including taxable
                  capital gains), in the same amount, in the same manner and at
                  the same time or times as would have been the case if such
                  option had not been exercised.

The Corporation shall be deemed to have made such due provision for payment if,
and only if, it has deposited or caused to be deposited with the Trustee under
the terms of the irrevocable trust agreement, and solely for the benefit of the
Debentureholders for the purpose stated therein, cash or securities issued or
guaranteed by the Government of Canada which will be sufficient, in the opinion
of an independent chartered accountant or investment dealer acceptable to the
Trustee, to provide for the Payments.

The Trustee shall hold in trust, all monies or securities deposited with it
pursuant to this section 7.3, and shall apply the deposited monies and the money
from such securities in accordance with this Indenture to the payment of
principal of, interest and premium, if any, on the Debentures.

7.4      TRUSTEE UNABLE TO APPLY MONEY OR DEBENTURES

If the Trustee is unable to apply any money or securities in accordance with
section 7.3 by reason of any legal proceeding or by reason of any order or
judgment of any Court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Corporation's obligations under this
Indenture and the Debentures shall be revived and reinstated as though no
deposit of money or securities had occurred pursuant to section 7.3 until such
time as the Trustee is permitted to apply all such money or securities in
accordance with section 7.3; provided that if the Corporation has made any
principal or interest payments or paid any premium, if any, on the Debentures
because of the reinstatement of its obligations, the Corporation shall be
subrogated to the rights of the Debentureholders of such Debentures to receive
such payment from the money or securities held by the Trustee. Notwithstanding
the foregoing, upon proof being given to the reasonable satisfaction of the
Trustee that all the Debentures of a particular series and the premium, if any,
thereon, and interest (including interest on amounts in default) thereon and
other moneys payable in respect thereof have been paid or satisfied or that, all
the outstanding Debentures of a particular series having matured or having been
duly called for redemption, or the Trustee having been given irrevocable
instructions by the Corporation to publish within ninety (90) days notice of
redemption of all the outstanding Debentures of a particular series, such
payment and/or redemption has been duly and effectually provided for by payment
to the Trustee or otherwise, and upon payment of all costs, charges and expenses
properly incurred by the Trustee in relation to the supplemental indenture
providing for the issue of such series of Debentures and all interest thereon,
or upon provision satisfactory to the Trustee being made therefor, the Trustee
shall at the request and at the expense of the Corporation, execute and deliver
to the Corporation such deeds or other instruments as shall be requisite to
evidence the satisfaction and discharge of the supplemental indenture providing
for the issue of such series of Debentures and to release the Corporation from
the covenants therein contained.

7.5      DISCHARGE

Upon proof being given to the reasonable satisfaction of the Trustee that all
the Debentures and interest (including interest on amounts in default) thereon
have been paid or satisfied or that, all the outstanding Debentures having
matured, such payment has been duly provided for by payment to the Trustee or
otherwise, and upon payment of all costs, charges and expenses properly incurred
by the Trustee in relation to this Indenture and all interest thereon and the
remuneration of the Trustee, or upon provision satisfactory to the Trustee being
made therefor, the Trustee shall,

                                     - 37 -

at the request and at the expense of the Corporation, execute and deliver to the
Corporation such deeds or other instruments as shall be necessary to evidence
the satisfaction and discharge of this Indenture and to release the Corporation
from its covenants contained herein except those relating to the indemnification
of the Trustee.

otherwise, whereby all or substantially all of its undertaking, property and
assets would become the property of any other Person or, in the case of any such
amalgamation, of the continuing corporation resulting therefrom, but may do so
if:

         (a)      such other Person or continuing corporation is a corporation
                  (the "Successor Corporation") incorporated under the laws of
                  Canada or any province thereof;

         (b)      the Successor Corporation shall execute, prior to or
                  contemporaneously with the completion of such transaction,
                  such indenture supplemental hereto and other instruments (if
                  any) as are satisfactory to the Trustee and in the opinion of
                  Counsel are necessary or advisable to evidence the assumption
                  by the Successor Corporation of the liability for the due and
                  punctual payment of all the Debentures and the interest
                  thereon and all other moneys payable thereunder and the

                  agreement to observe and perform all the covenants and
                  obligations of the Corporation under this Indenture;

         (c)      such transaction shall, to the satisfaction of the Trustee and
                  in the opinion of Counsel, be upon such terms as substantially
                  to preserve and not to impair any of the rights and powers of
                  the Trustee or of the Debentureholders hereunder and upon such
                  terms as are not in any way prejudicial to the interests of
                  the Debentureholders; and

         (d)      no condition or event shall exist in respect of the
                  Corporation or the Successor Corporation, either at the time
                  of such transaction or immediately thereafter after giving
                  full effect thereto, which constitutes or would, after the
                  giving of notice or the lapse of time or both, constitute an
                  Event of Default hereunder.

8.2      VESTING OF POWERS IN SUCCESSOR

Whenever the conditions of section 8.1 have been duly observed and performed,
the Trustee shall execute and deliver the supplemental indenture provided for in
Article 12 and thereupon:

                  may exercise each and every right and power of the Corporation
                  under this Indenture in the name of the Corporation or
                  otherwise, and any act or proceeding by any provision of this
                  Indenture required to be done or performed by any Directors or
                  officers of the Corporation may be done and performed with
                  like force and effect by the like directors or officers of
                  such Successor Corporation; and

         (b)      the Corporation shall be released and discharged from
                  liability under this Indenture and the Trustee may execute any
                  documents which it may be advised are necessary or advisable
                  for effecting or evidencing such release and discharge.

Debentures, as the case may be, other than a meeting convened for the purpose of
considering a resolution proposed to be passed as an Extraordinary Resolution,
as to which the provisions of section 9.11 shall be applicable, a quorum shall
consist of Holders present in person or by proxy and representing at least 25%
in principal amount of the outstanding Debentures or Debentures of such series,
as the case may be. If a quorum of the Debentureholders or the Holders of
Debentures of such series, as the case may be, shall not be present within 30
minutes from the time fixed for holding any such meeting, the meeting, if
convened by the Debentureholders or the Holders of Debentures of such series or

Day) at the same time and place. At the adjourned meeting the Debentureholders
or the Holders of Debentures of such series, as the case may be, present in

the meeting was originally convened notwithstanding that they may not represent
25% of the principal amount of the outstanding Debentures or Debentures of such

consent of the Holders of a majority in principal amount of the Debentures or

any such meeting and no notice of such adjournment need be given except such
notice, if any, as the meeting may prescribe.

9.6      SHOW OF HANDS

Every question submitted to a meeting shall be decided in the first place by a
majority of the votes given on a show of hands except that votes on
Extraordinary Resolutions shall be given in the manner hereinafter provided. At
such meeting, unless a poll is duly demanded as herein provided, a declaration
by the chairman that a resolution has been carried or carried unanimously or by
a particular majority or lost or not carried by a particular majority shall be
conclusive evidence of the fact.

9.7      POLL

On every Extraordinary Resolution, and on any other question submitted to a
meeting, when demanded by the chairman or by a Holder and/or proxies for Holders
holding at least 5% of the principal amount of the Debentures or the Debentures
of a series, as the case may be, represented thereat, a poll shall be taken in
such manner and either at once or after an adjournment as the chairman shall
direct. Questions other than Extraordinary Resolutions shall, if a poll is
taken, be decided by the votes of the Holders of a majority in principal amount
of the Debentures or the Debentures of such series, as the case may be,
represented at the meeting and voted on the poll.

9.8      VOTING

On a show of hands every Person who is present and entitled to vote, whether as
a Holder or as proxy, shall have one vote. On a poll each Holder present in

Debentureholders or the Holders of the Debentures of a series shall be entitled
to one vote in respect of each $1,000 principal amount of Debentures or
Debentures of such series, as the case may be, of which he shall then be the
Holder. A proxy need not be a Holder of Debentures of any series. In the case of
joint registered Holders of a Debenture, any one of them present in person or by
proxy at the meeting may vote in the absence of the other or others; but in case
more than one of them are present in person or by proxy, they shall vote
together in respect of the Debentures of which they are joint registered
Holders.

                  adjournment thereof or to appoint a proxy or proxies to
                  represent them at such meeting and at any adjournment thereof,

                  the Corporation or to the Trustee at the place where the same

                  though the instruments themselves were produced at the
                  meeting.

meeting, in respect of the proceedings of which minutes shall have been made,

                  or ancillary hereto), any covenant or other provision
                  contained herein or in any indenture supplemental hereto which
                  is expressed to be effective only so long as any Debentures of

                  required resolution or consent of the Holders of the
                  Debentures of such series in the same manner as if the
                  Debentures of such series were the only Debentures outstanding

                  to be recorded at the place where, such certificate is made,
                  that the Person signing such request, direction, notice,
                  consent or other instrument or writing acknowledged to him the
                  execution thereof, or by an affidavit of a witness of such
                  execution or in any other manner which the Trustee may
                  consider adequate; and

         (b)      the fact of the holding by any Person executing such request,
                  direction, notice, consent or other instrument or writing of

                  deposit of such Bearer Debentures with the Trustee or by a
                  certificate executed by any bank, trust company or other
                  depositary satisfactory to the Trustee certifying that on the
                  date therein mentioned such Person had on deposit with such
                  depositary the Bearer Debentures described in such certificate

                  deposited until the expiration of the time specified in such
                  certificate.

The Trustee may, nevertheless, in its discretion require further proof in cases
where it considers further proof necessary or desirable or may accept such other
proof as it shall consider proper.

                  exercise that degree of care, diligence and skill that a

                  harmless the Trustee against the costs, charges and expenses
                  and liabilities to be incurred thereby and any loss and damage
                  it may suffer by reason thereof. None of the provisions
                  contained in this Indenture shall require the Trustee to
                  expend or risk its own funds or otherwise incur financial
                  liability in the performance of any of its duties or in the
                  exercise of any of its rights or powers unless indemnified as
                  aforesaid;

         (c)      The Trustee may, before commencing or at any time during the
                  continuance of any such act, action or proceeding, require the

                  Debentures the Trustee shall issue receipts; and

                  the Trustee of liability or entitles it to rely upon any
                  evidence submitted to it is subject to the provisions of

                  the Corporation shall furnish to the Trustee such additional
                  evidence of compliance with any provisions hereof, and in such
                  form, as may be prescribed by Indenture Legislation or as the

                  expressed therein, upon statutory declarations, opinions,
                  reports, certificates or other evidence referred to in
                  subsection 11.4(a) provided that the Trustee examines the same
                  and determines that such evidence complies with the applicable
                  requirements of this Indenture and of Indenture Legislation;
                  and

         (c)      The Trustee may employ or retain such counsel, auditors,
                  accountants, appraisers or other experts or advisers, whose
                  qualifications give authority to any opinion or report made by

                  discharging its duties hereunder and shall not be responsible
                  for any misconduct on the part of any of them.

11.9     ACTION BY TRUSTEE TO PROTECT INTERESTS

The Trustee shall have the power to institute and maintain all and any such
actions, suits or proceedings as it may consider necessary or expedient to
preserve, protect or enforce its interests and the interests of the Holders of
the Debentures.

11.10    REPLACEMENT OF TRUSTEE

The Trustee may resign from the trusts hereunder and thereupon be discharged
from all further duties and liabilities hereunder by giving to the Corporation
three months' notice in writing or such shorter notice as the Corporation may
accept as sufficient. The Debentureholders by Extraordinary Resolution shall
have power at any time to remove the Trustee and to appoint a new trustee
hereunder. In the event of the Trustee resigning or being removed as aforesaid
or being dissolved, becoming bankrupt, going into liquidation or otherwise
becoming incapable of acting hereunder, the Corporation shall forthwith appoint
a new trustee hereunder unless a new trustee has already been appointed by the
Debentureholders; failing such appointment by the Corporation, the retiring
trustee hereunder or any Debentureholder may apply to a Judge of the Ontario
High Court, on such notice as such Judge may direct, for the appointment of a
new trustee hereunder; but any trustee so appointed by the Corporation or by the
Court shall be subject to removal as aforesaid by the Debentureholders. Any new
trustee hereunder appointed under any provision of this section 11.10 shall be a
corporation authorized and qualified to carry on the business of a trust company
in the Province of Ontario and every other jurisdiction where such authorization
or qualification is necessary to enable it to act as a trustee hereunder and
shall certify that it will not have any material conflict of interest upon
becoming trustee hereunder. On any new appointment the new trustee shall be
vested with the same powers, rights, duties and responsibilities as if it had
been originally named herein as Trustee.

Any corporation into which the Trustee may be merged or with which it may be
consolidated or amalgamated, or any corporation resulting from any merger,
consolidation or amalgamation to which the Trustee shall be a party, shall be
the successor Trustee under this Indenture without the necessity of the
execution of any instrument or any further act.

11.11    ACCEPTANCE OF TRUSTS

The Trustee accepts the trusts in this Indenture declared and provided for and
agrees to perform the same upon the terms and conditions herein set forth and in
trust for the various Persons who shall from time to time be Debentureholders,
subject to the terms and conditions herein set forth.

11.12    INDEMNIFICATION OF TRUSTEE

Except for its gross negligence or wilful misconduct: (a) the Trustee shall not
be liable for any act done or step taken or omitted by it in good faith, or for
any mistake of fact or law; and (b) the Company agrees to indemnify and save
harmless the Trustee from and against all claims, demands, action, suits or
other proceedings by whomsoever made, prosecuted or brought and from all loss,
costs, damages and expenses in any manner based upon, occasioned by or
attributable to any act of the Trustee in the execution of its duties hereunder.
It is understood and agreed that this indemnification shall survive the
termination of this Indenture.

                                   SCHEDULE A

                         CONVERTIBLE DEBENTURES SERIES 1

to the foregoing Indenture made as of March 25, 1998 between Benz Energy Ltd.
and Montreal Trust Company of Canada, as Trustee.

1.       MATURITY, INTEREST, CURRENCY OF DENOMINATION. The first series of
         Debentures to be issued, certified and delivered hereunder (the
         "Convertible Debentures Series 1") shall have the rights, conditions,
         limitations and privileges in this Schedule set forth, shall be
         denominated in U.S. dollars, shall consist of and be limited to US
         $30,000,000 in principal amount of Debentures and shall be designated
         as Convertible Debentures Series 1, shall mature on March 31, 2003 (the
         "Maturity Date") and shall bear interest at 9% per annum from their
         date, payable in lawful money of the United States after as well as
         before maturity, default and judgment, with interest on amounts in
         default at the same rate, semi-annually in arrears on March 31 and
         September 30, in each year, the first of such payments to be made on
         September 30, 1998.

2.       INTEREST ACCRUED. The Convertible Debentures Series 1 shall cease to
         bear interest (i) from their date of redemption unless, upon due
         presentation, payment of the principal in respect of the Convertible
         Debenture Series 1 is improperly withheld or refused or unless a
         default is otherwise made in respect of such payment, in which event
         interest shall continue to accrue as provided in the Indenture, or (ii)
         where the right to convert the Convertible Debentures Series 1 shall
         have been exercised in accordance with the provisions of the Indenture;
         or (iii) respectively, from the interest payment date last proceeding
         the day of conversion of the Convertible Debentures Series 1 or, if the
         Convertible Debentures Series 1 are converted prior to the first
         interest payment date, from the date of issue.

3.       INTEREST FOR LESS THAN ONE YEAR. When interest is required to be
         calculated in respect of a period of less than a full year, it shall be
         calculated on the basis of the actual number of calendar days in such
         year and the number of days elapsed.

4.       PAYMENT OF PRINCIPAL, INTEREST.

         (a)      Payment of principal in respect of each Convertible Debenture
                  Series 1 shall only be made against presentation and surrender
                  (or, in the case of part payment only, endorsement) of the
                  relevant Convertible Debenture Series 1 at the specified
                  office of any of the Paying Agents. Payments of interest due
                  on the Convertible Debentures Series 1 on an interest payment
                  date shall only be made against presentation and surrender
                  (or, in the case of part payment only, endorsement) of the
                  relevant Coupons at the specified office of any of the Paying
                  Agents. All payments of principal or interest shall be made in
                  U.S. dollars. Such payments will be made by transfer to a U.S.
                  dollar account maintained by the payee with a bank outside of
                  the United States or by a U.S. dollar cheque mailed to an
                  address, or delivered, outside the United States, subject in
                  all cases to any fiscal or other local laws or regulations
                  applicable thereto.

         (b)      If, at any time, payments in U.S. dollars cannot, in the
                  opinion of the Issuer or of the Paying Agents, be so made,
                  payments will be made in U.S. dollars in such other manner as
                  may be approved by the Issuer and the Paying Agents, subject
                  as aforesaid in paragraph (a) above. In the event that payment
                  cannot be made as provided in paragraph (a) above, notice of
                  the alternative manner of payment will be given to the
                  Debentureholders in accordance with Condition 12 below.

         (c)      If the due date for payment of any amount of principal or
                  interest in respect of a Convertible Debenture Series 1 is not
                  at any place of payment a business day, then the holder
                  thereof will not be entitled to payment at the relevant place
                  of payment of the amount due until the next following business
                  day at the relevant place of payment and will not be entitled
                  to any further interest or other payment in respect of any
                  such delay. In this paragraph, "business day" means any day on
                  which

                                       A-2

                  banks are open for business in Toronto, London, New York and
                  the relevant place of payment or (in the case of payment by
                  transfer to a U.S. dollar account as referred to in paragraph
                  (a) above) on which dealings in foreign currencies may be
                  carried on in each of Toronto, London, New York and such place
                  of payment.

5.       PAYMENT ON REDEMPTION. Each Convertible Debenture Series 1 must be
         presented for redemption together with all unmatured Coupons relating
         to such Convertible Debenture Series 1, failing which the full amount
         of any missing unmatured Coupon (or, in the case of payment not being
         made in full, that proportion of the full amount of the missing
         unmatured Coupons which the amounts so paid bears to the total amount
         due) will be deducted from the amount due for payment. Each amount so
         deducted shall be paid in the manner mentioned above against
         presentation and surrender (or, in the case of part payment only,
         endorsement) of such missing Coupon at any time before the expiry of
         six years after the date of redemption of the Convertible Debenture
         Series 1 or, if later, five years after the date on which such Coupon
         would have become due, but not thereafter.

6.       UNCLAIMED AMOUNTS. All monies paid by the Corporation to the
         Principal Paying Agent for the payment of principal or interest on
         any Convertible Debenture Series 1 which remain unclaimed at the end
         of two years after the principal on such Convertible Debenture
         Series 1 will have become due and payable shall be repaid to the
         Corporation and the holder of such Convertible Debenture Series 1 or
         any Coupon appertaining thereto or thereafter shall have only the
         rights of a creditor of the Corporation as described in the
         Indenture or such rights as may be otherwise prescribed by
         applicable law.

         Debentures Series 1 or holders of Coupons, fractions of US $0.01 shall
         be rounded down to the nearest whole cent.

                  Common Depository and shall bear the legend set forth in (a)
                  above. Members of, or participants in, Euroclear and Cedel

                  Indenture with respect to any Global Debenture held on their
                  behalf by the Common Depository, or under the Global
                  Debenture, and the Common Depository may be treated by the

                  owner of such Global Debenture for all purposes whatsoever.
                  Notwithstanding the foregoing, nothing herein shall prevent
                  the Issuer, the Trustee or any agent of the Issuer or the
                  Trustee, from giving effect to any written certification,
                  proxy or other authorization furnished by the Common
                  Depository or shall impair, as between the Common Depository
                  and the Agent Members, the operation of customary practices
                  governing the exercise of the rights of a Debentureholder.

         c.       Transfers of the Global Debenture shall be limited to
                  transfers of such Global Debenture in whole, but not in part,
                  to the Common Depository, its successors or their respective
                  nominees. Interests of beneficial owners in the Global
                  Debenture may be transferred in accordance with the rules and
                  procedures of Euroclear or Cedel Bank and this section.

                  Debenture upon request in accordance with the procedures of
                  Euroclear or Cedel Bank. Definitive Debentures shall be
                  transferred to all beneficial owners in exchange for their
                  beneficial interests in the Global Debenture if (i) the Common
                  Depository notifies the Issuer that it is unwilling or unable
                  to continue as Common Depository for the Global Debenture and
                  a successor depository is not appointed by the Issuer within
                  90 days of such notice or (ii) an Event of Default has
                  occurred and is continuing and the Trustee has received a
                  request from the Common Depository.

         d.       In connection with any transfer of beneficial interest in the
                  Global Debenture to beneficial owners pursuant to subsection
                  (c) of this section, the Common Depository shall reflect on
                  its books and records the date and cancellation of the Global
                  Debenture, and the Issuer shall execute, and the Trustee or
                  its agent shall authenticate and deliver, one or more
                  definitive Debentures in an amount equal to the principal
                  amount of the beneficial interest in the Global Debenture to
                  be transferred.

         e.       Any definitive Debenture delivered in exchange for an interest
                  in the Global Debenture pursuant to subsection (c) or
                  subsection (d) of this section shall bear the applicable
                  legend regarding transfer restrictions applicable to the
                  definitive Debenture set forth in the terms and conditions
                  relating to the relevant series of Debentures.

         f.       The Holder of the Global Debenture may grant proxies and
                  otherwise authorize any person, including Agent Members and
                  persons that may hold interests through Agent Members, to take
                  any action which a Debentureholder is entitled to take under
                  this Indenture or the Debentures.

         g.       Any definitive Debenture delivered in exchange for an interest
                  in the Global Debenture pursuant to subsection (c) or (d) of
                  this section will prior to delivery to the Debentureholder
                  have all matured Coupons as of such delivery date, which are
                  attached to such definitive Debenture, cancelled and voided by
                  the Trustee or its agent.

         h.       Each definitive Debenture shall bear the following legend on
                  the face thereof:

                           NEITHER THE CONVERTIBLE DEBENTURES NOR THE COMMON
                           SHARES ISSUABLE UPON CONVERSION OF THE CONVERTIBLE

9.       CONVERSION:

         a.       The Convertible Debentures Series 1 shall be convertible at
                  the option of the holder into Common Shares, at any time prior
                  to the close of business on March 27, 2003 (the "Time of
                  Expiry"), at a conversion price of Cdn. $1.70 per Common
                  Share, subject to adjustment in accordance with the Indenture
                  and subsection (h) hereof (the "Conversion Price").
                  Notwithstanding the foregoing, if a Convertible Debenture
                  Series 1 is called for redemption by the Corporation (as
                  discussed below), the right of the holder to convert the
                  Convertible Debenture Series 1 shall expire at the close of
                  business on the second business day immediately prior to the
                  date of redemption.

         b.       If the holder of Convertible Debentures Series 1 elects to
                  convert the Convertible Debentures Series 1 prior to the date
                  of the third semi-annual coupon with respect thereto, the
                  holder shall receive on such conversion a premium on the
                  number of Common Shares to be issued on such conversion
                  determined based upon the aggregate principal amount of
                  Convertible Debentures Series 1 to be converted by multiplying
                  .05 by the number of Common Shares to be so issued and
                  rounding down to the nearest whole number.

         c.       The holder of a Convertible Debenture Series 1 desiring to
                  convert such Convertible Debenture Series 1 in whole or in
                  part into Common Shares shall surrender such Convertible
                  Debenture Series 1 to the specified office of any of the
                  Conversion Agents, together with the Conversion Form on the
                  back of such Convertible Debenture Series 1 or any other
                  written notice in a form satisfactory to the Conversion Agent,
                  in either case duly executed by the holder or his executors or
                  administrators or other legal representatives or his or their
                  attorney duly appointed by an instrument in writing in form
                  and executed in a manner satisfactory to the Conversion Agent,
                  exercising his right to convert such Convertible Debenture
                  Series 1 in accordance with the provisions of the Indenture
                  and any agency agreement thereunder. Thereupon such
                  Debentureholder and/or, subject to payment of all applicable
                  stamp or security transfer taxes or other governmental charges
                  and compliance with all reasonable requirements of the Trustee
                  or the Conversion Agent, his nominee(s) or assignee(s) shall
                  be entitled to be entered in the books of the Corporation as
                  at the Date of Conversion (or such later date as is specified
                  in Subsection 9(d)) as the holder of the number of Common
                  Shares into which such Convertible Debenture Series 1 is
                  convertible in accordance with the provisions thereafter, the
                  Corporation shall deliver to such Debentureholder and/or,
                  subject as aforesaid, his nominee(s) or assignee(s), a
                  certificate or certificates for such Common Shares and, if
                  applicable, a cheque for any amount payable under Section 4.4
                  of the Indenture.

         d.       For the purposes of this Schedule, a Convertible Debenture
                  Series 1 shall be deemed to be surrendered for conversion on
                  the date (herein called "Date of Conversion") on which it is
                  so surrendered in accordance with the provisions hereof and,
                  in the case of a Convertible Debenture Series 1 so surrendered
                  by post or other means of transmission, on the date on which
                  it is received at the specified office of any of the
                  Conversion Agents; provided that if a Convertible Debenture
                  Series 1 is surrendered for conversion on a day on which the
                  register of Common Shares is closed,

                                       A-5

                  the Person or Persons entitled to receive Common Shares shall
                  become the holder or holders of record of such Common Shares
                  as at the date on which such registers are next reopened.

         e.       Any part, being US $5,000 or an integral multiple thereof, of
                  a Convertible Debenture Series 1 of a denomination in excess
                  of US $5,000 may be converted as provided in this Schedule and
                  all references in this Schedule and in the Indenture to
                  conversion of Convertible Debenture Series 1 shall be deemed
                  to include conversion of such parts.

         f.       The holder of any Convertible Debenture Series 1 of which part
                  only is converted shall, upon the exercise of his right of
                  conversion, surrender the said Convertible Debenture Series 1
                  to the Trustee or its agent, and the Trustee or its agent
                  shall cancel the same and definitive Convertible Debentures
                  Series 1 for the unconverted principal balance, in
                  denominations of U.S. $5,000, U.S. $10,000 and U.S. $50,000,
                  as applicable, with unmatured Coupons attached, will be
                  available at the offices of the Paying and Conversion Agents.

         g.       The holder of a Convertible Debenture Series 1 surrendered for
                  conversion in accordance with this Schedule shall be entitled
                  to receive accrued and unpaid interest in respect thereof up
                  to the interest payment date on or next preceding the Date of
                  Conversion of such Convertible Debenture Series 1, but there
                  shall be no payment or adjustment by the Corporation on
                  account of any interest accrued or accruing on such
                  Convertible Debenture Series 1 from the latest interest
                  payment date, and the Common Shares issued upon such
                  conversion shall rank only in respect of dividends declared in
                  favour of shareholders of record on and after the Date of
                  Conversion or such later date as such holder shall become the
                  holder of record of such Common Shares pursuant to Subsection
                  (d) of this Section 9, from which applicable date they will
                  for all purposes be and be deemed to be issued and outstanding
                  as fully paid and non-assessable Common Shares.

         h.       The Conversion Price otherwise applicable hereunder shall be
                  converted to U.S. dollars based upon the Exchange Rate as of
                  the last day in the calendar quarter preceding the Date of
                  Conversion, where "Exchange Rate" means, on any date, for any
                  conversion of U.S. dollars into Canadian dollars, or VICE
                  VERSA, the applicable spot buying rate for Canadian dollars or
                  United States dollars, as the case may be, quoted by The Bank

                  such date if it is a business day or on the immediately
                  preceding business day if such date is not a business day.

         i.       Any Officers' Certificate required by the Indenture after the
                  occurrence of any event which requires an adjustment or
                  readjustment as provided in section 4.3 of the Indenture shall

         consecutive trading day period ending not more than five days prior to

                  notation of ownership or writing thereon or any notice of any
                  previous loss or theft thereof) for the purpose of making
                  payments in relation thereto and for all other purposes.

2.       STATUS

4.       INTEREST ACCRUED

The Convertible Debentures Series 1 shall cease to bear interest (i) from their
date of redemption unless, upon due presentation, payment of the principal in
respect of the Convertible Debentures Series 1 is improperly withheld or refused
or unless a default is otherwise made in respect of such payment, in which event
interest shall continue to accrue as provided in the Indenture, or (ii) where
the right to convert the Convertible Debentures Series 1 shall have been
exercised in accordance with the provisions of the Indenture; or (iii)
respectively, from the interest payment date last proceeding the day of
conversion of the Convertible Debentures Series 1, or if the Convertible

5.       PAYMENT OF PRINCIPAL, INTEREST

         (a)      Payment of principal in respect of each Convertible Debenture
                  Series 1 shall only be made against presentation and surrender
                  (or, in the case of part payment only, endorsement) of the
                  relevant Convertible Debentures Series 1 at the specified
                  office of any of the Paying Agents. Payments of interest due
                  on the Convertible Debentures Series 1 on an interest payment
                  date shall only be made against presentation and surrender
                  (or, in the case of part payment only, endorsement) of the
                  relevant Coupons at the specified office of any of the Paying
                  Agents. All payments of principal or interest shall be made in
                  U.S. dollars. Such payments will be made by transfer to a U.S.
                  dollar account maintained by the payee with a bank outside of
                  the United States or by a U.S. dollar cheque mailed to an
                  address, or delivered, outside the United States, subject in
                  all cases to any fiscal or other local laws or regulations
                  applicable thereto.

         (b)      If, at any time, payments in U.S. dollars cannot, in the
                  opinion of the Issuer or of the Paying Agents, be so made,
                  payments will be made in U.S. dollars in such other manner as
                  may be approved by the Issuer and the Paying Agents, subject
                  as aforesaid in paragraph (a) above. In the event that payment
                  cannot be made as provided in paragraph (a) above, notice of
                  the alternative manner of payment will be given to the
                  Debentureholders in accordance with Condition 15 below.

         (c)      If the due date for payment of any amount of principal or
                  interest in respect of a Convertible Debenture Series 1 is not
                  at any place of payment a business day, then the holder
                  thereof will not be entitled to payment at the relevant place
                  of payment of the amount due until the next following business
                  day at the relevant place of payment and will not be entitled
                  to any further interest or other payment in respect of any
                  such delay. In this paragraph, "business day" means any day on
                  which banks are open for business in Toronto, London, New York
                  and the relevant place of payment or (in the case of payment
                  by transfer to a U.S. dollar account as referred to in
                  paragraph (a) above) on which dealings in foreign currencies
                  may be carried on in each of Toronto, London, New York and
                  such place of payment.

6.       REDEMPTION, PURCHASE AND CANCELLATION

Unless previously redeemed, purchased, exercised or cancelled, the Convertible
Debentures Series 1 will be redeemed at their principal amount on March 31,
2003. Each Convertible Debenture Series 1 must be presented for redemption
together with all unmatured Coupons relating to such Convertible Debentures
Series 1, failing which the full amount of any missing unmatured Coupon (or, in
the case of payment not being made in full, that proportion of the full amount
of the missing unmatured Coupons which the amounts so paid bears to the total
amount due) will be deducted from the amount due for payment. Each amount so
deducted shall be paid in the manner mentioned above against presentation and
surrender (or, in the case of part payment only, endorsement) of such missing
Coupon at any time before the expiry of six years after the date of redemption
of the Convertible Debenture Series 1 or, if later, five years after the date on
which such Coupon would have become due, but not thereafter.



<PAGE>


                                      A-23

Provided that no Event of Default has occurred and is continuing, the Issuer may
at any time purchase all or any of the Convertible Debentures Series 1 at any
price in the open market, by invitation for tenders or by private contract.
Convertible Debentures Series 1 so purchased shall be delivered to the Trustee
and cancelled by it and may not be reissued or re-sold, and except as otherwise
provided in the Indenture, no Convertible Debentures Series 1 shall be issued in
substitution therefor.

7.       UNCLAIMED AMOUNTS

All monies paid by the Issuer to the Principal Paying Agent for the payment of
principal or interest on any Convertible Debenture Series 1 which remain
unclaimed at the end of two years after the principal on such Convertible
Debenture Series 1 will have become due and payable shall be repaid to the
Issuer and the holder of such Convertible Debenture Series 1 or any Coupon
appertaining thereto or thereafter shall have only the rights of a creditor of
the Issuer as described in the Indenture or such rights as may be otherwise
prescribed by applicable law.

8.       ROUNDING AMOUNTS

When making payments to holders of Convertible Debentures Series 1 or holders of
Coupons, fractions of US$0.01 shall be rounded down to the nearest whole cent.

9.       CONVERSION

The Convertible Debentures Series 1 are convertible at the option of the holder
into common shares of the Issuer, as constituted on the date of issue, (the
"Common Shares"), at any time prior to the close of business on March 27, 2003,
at a conversion price of Cdn.$1.70 per Common Share, subject to adjustment in
accordance with the Indenture (the "Conversion Price"). Notwithstanding the
foregoing, if a Convertible Debenture Series 1 is called for redemption by the
Issuer, the right of the holder to convert the Convertible Debenture Series 1
shall expire at the close of business on the second business day immediately
prior to the date of redemption.

The Conversion Price otherwise applicable hereunder shall be converted to U.S.
dollars based upon the Exchange Rate as of the last day in the calendar quarter
preceding the date of conversion, where "Exchange Rate" means, on any date, for
any conversion of U.S. dollars into Canadian dollars, or VICE VERSA, the
applicable spot buying rate for Canadian dollars or United States 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 a business day.

If the holder of Convertible Debentures Series 1 elects to convert the
Convertible Debentures Series 1 prior to the date of the third semi-annual
coupon with respect thereto, the holder shall receive on such conversion a
premium on the number of Common Shares to be issued on such conversion
determined based upon the aggregate principal amount of Convertible Debentures
Series 1 to be converted by multiplying .05 by the number of Common Shares to be
so issued and rounding down to the nearest whole number.

The holder of a Convertible Debenture Series 1 desiring to convert such
Convertible Debenture Series 1 in whole or in part into Common Shares shall
surrender such Convertible Debenture Series 1 to the specified office of any of
the Conversion Agents, together with the Conversion Form on the back of such
Convertible Debenture Series 1 or any other written notice in a form
satisfactory to the Conversion Agent, in either case duly executed by the holder
or his executors or administrators or other legal representatives or his or
their attorney duly appointed by an instrument in writing in form and executed
in a manner satisfactory to the Conversion Agent, exercising his right to
convert such Convertible Debenture Series 1 in accordance with the Indenture and
the Agency Agreement.

Any part, being US$5,000 or an integral multiple thereof, of a Convertible
Debenture Series 1 of a denomination in excess of US$5,000 may be converted.
Certificates for Common Shares issued on conversion will be delivered by mail


<PAGE>


                                      A-24

free of charge (but uninsured and at the risk of the person entitled thereto)
within 14 days of the date of conversion. If only a part of the Convertible
Debentures Series 1 held by a holder is converted, after the Convertible
Debentures cease to be represented by a Global Debenture, definitive Convertible
Debentures Series 1 for the unconverted principal balance, in denominations of
U.S.$5,000, U.S.$10,000 and U.S.$50,000, as applicable, with unmatured Coupons
attached, will be available at the offices of the Paying and Conversion Agents
(including the Paying and Conversion Agent in Luxembourg).

The Indenture provides for the adjustment of the Conversion Price upon the
following events:

         (a)      The subdivision or consolidation of the outstanding Common
                  Shares;

         (b)      the issue of any Common Shares to holders of Common Shares by
                  way of stock dividends, other than an issue of Common Shares
                  to holders of Common Shares who have elected to receive
                  dividends in shares in lieu of receiving cash dividends paid
                  in the ordinary course;

         (c)      the issue of rights, options or warrants to all or
                  substantially all of the holders of Common Shares entitling
                  them to acquire Common Shares or securities convertible into
                  Common Shares (unless the rights, options or warrants are
                  exercisable within a period of 45 days from their issue at a
                  price equal to or greater than 95% of the Current Market Price
                  of the Common Shares); and

         (d)      the distribution to all or substantially all of the holders of
                  Common Shares of any other class or of 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).

There will be no adjustment of the Conversion Price in respect of any event
described in (b), (c) or (d) above if the holders of the Convertible Debentures
are allowed to participate as though they had converted their Convertible
Debentures prior to the applicable record date or effective date.

The Issuer will give at least ten days notice to holders of Convertible
Debentures of the record date for any of the above events other than a
subdivision or consolidation of the Common Share. Except as stated above, no
adjustment will be made in the Conversion Price as a result of the issuance of
Common Shares at less than the then Current Market Price or Conversion Price.
The Current Market Price per Common Share at any date shall be the weighted
average price per share for Common Shares for 20 consecutive trading days
commencing not more than 30 trading days and ending not less than five trading
days before such date on the principal stock exchange in Canada on which the
Common Shares are traded. The weighted average price shall be determined by
dividing the aggregate sale price of all Common Shares so sold. The Issuer will
not be required to make adjustments in the Conversion Price unless the
cumulative effect of such adjustments would change the Conversion Price then in
effect by at least 1%. Any adjustment not so made will be carried forward and
taken into account in any subsequent adjustment.

The Indenture requires the Issuer to deliver an officers' certificate specifying
the nature of the event requiring any adjustment or readjustment as specified
above and the adjustment necessitated thereby. Such officers' certificate will
be available at the specified offices of any of the Paying or Conversion Agents.

10.      REQUIRED CONVERSION

The Issuer may, at any time after September 30, 1999 and prior to maturity, by
notice in writing given to the holders thereof, require that all outstanding
Convertible Debentures Series 1 be converted into Common Shares if the weighted
average trading price of the Common Shares on the principal stock exchange in
Canada on which the Common Shares are traded during a 20 consecutive trading day
period ending not more than five days prior to the giving of such notice is not
less than 140% of the Conversion Price then in effect.

11.      REDEMPTION

The Convertible Debentures Series 1 are redeemable, in whole or in part, at the
option of the Issuer at any time after March 31, 2002 and prior to maturity at
100% of the principal amount thereof to be redeemed, together with accrued and
unpaid interest. At the Maturity Date, 100% of the principal amount of the
Convertible Debentures Series 1 will be repaid together with accrued and unpaid
interest.

12.      MEETINGS OF DEBENTUREHOLDERS AND MODIFICATION

The Indenture contains provisions for convening meetings of the Debentureholders
to consider any matter affecting their interests, including the modification by
Extraordinary Resolution of these Terms and Conditions or the provisions of the
Indenture.

The Indenture provides that modifications and alterations thereto and to the
Convertible Debentures issued thereunder may be made if authorized by an
Extraordinary Resolution. Such a resolution must be passed by the affirmative
vote of the holders of not less than 66 2/3% of the principal amount of the
Debentures (or in the case of a serial meeting, where the rights of the
holders of Debentures of one or more series are affected differently than the
rights of the holders of any other series, of the principal amount of the
Debentures of the series so affected) issued under the Indenture represented
at a meeting at which holders of more than 25% of the principal amount of the
Debentures (or Debentures of a particular series, in the case of a serial
meeting) then outstanding are present in person or by proxy; provided,
however, that if a meeting or serial meeting is adjourned because not more
than 25% of the principal amount of such Debentures is present in person or
by proxy then at the adjourned meeting an extraordinary resolution may be
passed by the affirmative vote of the holders of not less than 66 2/3% of the
principal amount of the Debentures represented at the meeting or serial
meeting, as the case may be. The term Extraordinary Resolution shall also
include an instrument signed by the holders of not less than 66 2/3% of the
outstanding Debentures or the Debentures of a particular series, as the case
may be. An Extraordinary Resolution passed at any meeting of the
Debentureholders will be binding on all Debentureholders, whether or not they
are present at the meeting, and on all the Couponholders.

The Indenture also permits the Issuer and the Trustee, without the consent of
holders of Convertible Debentures, to enter into indentures supplemental to the
Indenture for certain purposes, including without limitation (i) making
provisions not inconsistent with the Indenture as may be necessary of desirable
with respect to matters or questions arising under the Indenture which do not
affect the substance thereof and which in the opinion of the Trustee, it may be
expedient to make, provided that the Trustee shall be of the opinion that such
provisions and modifications will not be prejudicial to the interests of the
Debentureholders, (ii) providing for the issue, as permitted by the Indenture,
of Debentures of any one or more series, (iii) making any modification of any of
the provisions of the Indenture or the Convertible Debentures which is of a
formal, minor or technical nature, (iv) making any additions to, deletions from
or alteration of the provisions of the Indenture which, in the opinion of the
Trustee, are not materially prejudicial to the interests of the Debentureholders
and which are necessary or advisable in order to incorporate, reflect or comply
with legislation applicable to indentures, (v) correcting or rectifying any
ambiguities, defective provisions, errors or omissions in the Indenture,
provided that, in the opinion of the Trustee, the rights of the Trustee and the
Debentureholders are in no way prejudiced thereby and (vi) any other purpose not
inconsistent with the terms of the Indenture provided that, in the opinion of
the Trustee, the rights of the Trustee and of the Debentureholders are in no way
prejudiced thereby.

13.      EVENTS OF DEFAULT

If an Event of Default described in clause (a) or (b) below with respect to
Debentures of any series at the time outstanding occurs and is continuing, then
in every such case the Trustee or the Holders of not less than 25% in principal
amount of the outstanding Debentures of that series may declare the principal
amount of all the Debentures of that series to be due and payable immediately,
by a notice in writing to the Issuer (and to the Trustee if given by Holders),
and upon any such declaration such principal amount (or specified portion
thereof) shall become immediately


<PAGE>


                                      A-26

due and payable. If an Event of Default described in clause (c), (d), (e), (f),
(g), (h) or (i) below occurs and is continuing, then in every such case the
Trustee or the Holders of not less than 25% in principal amount of all the
Debentures then outstanding may declare the principal amount of all the
outstanding Debentures to be due and payable immediately, by a notice in writing
to the Issuer (and to the Trustee if given by the Holders) and upon any such
declaration such principal amount (or specified portion thereof) shall become
immediately due and payable.

"Event of Default" means any one of the following events (whatever the reason
for such Event of Default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of and administrative or governmental
body):

         (a)      default in the payment of any interest upon any Debenture, or
                  any related Coupon, when such interest or Coupon becomes due

                  days; or

         (b)      default in the payment of the principal of (or premium, if
                  any, on) any Debenture, as and when it shall become due and
                  payable at its Maturity, upon redemption, by declaration or
                  otherwise; or

         (c)      default in the performance, or breach, of any covenant or
                  warranty of the Issuer in the Indenture (other than a covenant
                  or warranty a default in performance of which or breach of
                  which is elsewhere in this section specifically dealt with or
                  which has expressly been included in the Indenture solely for
                  the benefit of one or more series of Debentures other than
                  that series), and continuance of such default or breach for a
                  period of 30 days after there has been given, by registered or
                  certified mail, to the Issuer by the Trustee or to the Issuer
                  and the Trustee by the Holders of at least 25% in principal
                  amount of all outstanding Debentures a written notice
                  specifying such default or breach and requiring it to be
                  remedied and stating that such notice is a "Notice of Default"
                  hereunder; or

         (d)      the entry of a decree or order by a court having jurisdiction
                  in the premises adjudging the Issuer or any Material
                  Subsidiary a bankrupt or insolvent under any bankruptcy,
                  insolvency or analogous laws or appointing a receiver,
                  liquidator, assignee, trustee, sequestrator, rehabilitator (or
                  other similar official) of the Issuer or any Material
                  Subsidiary or of any substantial part of their respective
                  properties, or ordering the winding up or liquidation of their
                  respective affairs, and the continuance of any such decree or
                  order unstayed and in effect for a period of 90 consecutive
                  days; or

         (e)      the institution by the Issuer or any Material Subsidiary of
                  proceedings to be adjudicated a bankrupt or insolvent, or the
                  consent by it to the institution of bankruptcy or insolvency
                  proceedings against it under any bankruptcy, insolvency or
                  analogous laws, or the consent by it to the filing of any such
                  petition or to the appointment of a receiver, liquidator,
                  assignee, trustee, sequestrator, rehabilitator (or other
                  similar official) of the Issuer or any Material Subsidiary or
                  of any substantial part of their respective properties, or the
                  making by the Issuer or any Material Subsidiary of an
                  assignment for the benefit of creditors, or the admission by
                  the Issuer or any Material Subsidiary in writing of its
                  inability to pay its debts generally as they become due; or

         (f)      if (i) any other Debt of the Issuer or any Material Subsidiary
                  becomes due and payable prior to its Stated Maturity by reason
                  of an event of default (howsoever defined) or (ii) any such
                  Debt of the Issuer or any Material Subsidiary is not paid when
                  due or, as the case may be, within any applicable grace period
                  or (iii) the Issuer or any Material Subsidiary fails to pay
                  when due (or, as the case may be, within any applicable grace
                  period) any amount payable by it under any present or future
                  guarantee for, or indemnity in respect of, any Indebtedness of
                  any Person or (iv) any security given by the Issuer or any
                  Material Subsidiary for any Indebtedness of any Person or any
                  guarantee or indemnity of Debt of any Person by the Issuer or
                  any Material Subsidiary becomes enforceable by reason of
                  default in relation thereto and steps are taken to enforce
                  such security save in any such case where there is a bona fide
                  dispute as to whether the relevant Debt or any such guarantee
                  or indemnity

                                      A-27

                  as aforesaid shall be due and payable (following any
                  applicable grace period), PROVIDED that in each such case the
                  Debt exceeds in the aggregate U.S.$1,500,000 and in each such
                  case such event continues unremedied for a period of 30
                  calendar days (or such longer period as the Trustee may in its
                  sole discretion consent to in writing upon receipt of written
                  notice from the Issuer); or

         (g)      if there is any final judgment or judgments for the payment of
                  money exceeding in the aggregate U.S.$1,500,000 outstanding
                  against the Issuer or any Material Subsidiary which has been
                  outstanding for more than 60 calendar days from the date of
                  its entry and shall not have otherwise been discharged in full
                  or stayed by appeal, bond or otherwise; or

         (h)      if the Issuer or any Material Subsidiary shall generally fail
                  to pay its Debts as such Debts come due (except Debts which
                  the Issuer or such Material Subsidiary, as the case may be,
                  may contest in good faith generally) or shall be declared or
                  adjudicated by a competent court to be insolvent or bankrupt,
                  shall consent to an entry of an order of relief against it in
                  an involuntary bankruptcy case, shall enter into any
                  assignment or other similar arrangement for the benefit of its
                  creditors or shall consent to the appointment of a custodian
                  (including, without limitation, a receiver, liquidator or
                  trustee); or

         (i)      if a warranty, representation, or other statement made by or
                  on behalf of the Issuer contained in the Indenture, the
                  Debentures or any certificate or other agreement furnished in
                  compliance with such documents is false in any material
                  respect when made and (except where the Trustee shall have
                  certified to the Issuer that it considers such falsity to be
                  incapable of remedy, in which case no such notice or
                  continuation as is hereinafter mentioned will be required)
                  such falsity continues for a period of 30 calendar days (or
                  such longer period as the Trustee may in its absolute
                  discretion permit) next following the service by the Trustee
                  on the Issuer of notice requiring the same to be remedied.

14.      REPLACEMENT OF CONVERTIBLE DEBENTURES SERIES 1 AND COUPONS

If any Convertible Debenture or Coupon shall at any time become mutilated,
defaced, destroyed, stolen or lost, it may be replaced at the cost of the
claimant at the specified office of the Replacement Agent or the Trustee upon
provision of such evidence, indemnity, security or otherwise as the Issuer
determines satisfactory. Mutilated or defaced Convertible Debentures Series 1 or
Coupons must be surrendered before replacements will be issued.

15.      NOTICES

In addition to notice to the holders of Convertible Debentures Series 1 as
provided in the Indenture, all notices to holders of Convertible Debentures
Series 1 shall be published in the Financial Times, or such other leading daily
financial newspaper with general circulation in Europe as the Trustee may
approve, and a daily leading newspaper with general circulation in Luxembourg,
which is expected to be the Luxembourg Wort, for so long as the Convertible
Debenture Series 1 are listed on the Luxembourg Stock Exchange.

16.      TAXATION

Payments of interest on the Convertible Debentures will be made subject to the
deduction of applicable Canadian withholding tax.

The Issuer will, subject to certain exceptions and limitations set forth below,
pay, as additional interest, such additional amounts (the "Additional Amounts")
to the holder of any Convertible Debenture as may be necessary in order that
every net payment of the principal or interest on such Convertible Debenture,
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 Canada (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


<PAGE>


                                      A-28

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 Canada (or any political subdivision thereof) otherwise
than by the mere holding of the Convertible Debenture or the receipt of payments
made under or with respect to the Convertible Debenture.

In addition, the Issuer will indemnify and hold harmless each holder of a
Convertible Debenture (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 Canada and paid by
the holder as a result of payments made under or with respect to the Convertible
Debentures. Any payment made pursuant to this paragraph shall be considered an
Additional Amount.

If, at any time, either of the Trustee and the Principal Paying Agent is
required by law to make any deduction or withholding from any sum payable by it
hereunder (or if thereafter there is any change in the rates at which or the
manner in which such deductions or withholdings are calculated), the Issuer
shall promptly notify the Trustee and the Principal Paying Agent and shall
deliver to the Trustee and the Principal Paying Agent, within thirty days after
it has made such payment to the applicable authority, an original receipt (or a
certified copy thereof) issued by such authority evidencing the payment to such
authority of all amounts so required to be deducted or withheld in respect of
each Convertible Debenture.

If the Issuer becomes generally subject at any time to any taxing jurisdiction
other than or in addition to Canada, references in these Conditions to Canada
shall be read and construed as reference to Canada and/or to such other
jurisdiction.

Any reference in these Conditions to interest in respect of the Convertible
Debentures shall be deemed also to refer to any Additional Amounts which may be
payable under this Condition.

17.      CERTAIN COVENANTS

         (a)      The Issuer will, so long as the Convertible Debentures are
                  outstanding, maintain Tangible Assets equal to or greater than
                  140% of Long Term Debt at all times including after redemption
                  of any redeemable preference shares of the Issuer or any
                  Subsidiary. This ratio shall be calculated no later than 135
                  days following the end of each of the Issuer's fiscal years,
                  and shall be based upon the Issuer's annual audited financial
                  statements, as adjusted for Tangible Assets, and the
                  Independent Reserve Reports.

         (b)      The Issuer and its Subsidiaries will not:

                  (i)      have outstanding more than U.S.$12,000,000 under the
                           EnCap Credit Facility for the period commencing 30
                           days from the date hereof; and

                  (ii)     use any of the net proceeds from the issuance of the
                           Convertible Debentures Series 1 to reduce the
                           Issuer's or its Subsidiaries' existing indebtedness;
                           provided, however that the Issuer may use net
                           proceeds in an amount not to exceed U.S.$6,000,000 to
                           reduce the amount outstanding under the EnCap Credit
                           Facility to an amount not less than U.S.$12,000,000.

18.      INDEMNIFICATION OF THE TRUSTEE

The Indenture contains provisions for the indemnification of the Trustee and for
its relief from responsibility, including provisions relieving it from taking
action unless indemnified to its satisfaction.



<PAGE>


                                      A-29

19.      AGENTS

The Issuer shall have the right, subject to the prior approval of the Trustee,
at any time to vary or terminate the appointment of any Paying Agent, Conversion
Agent or Replacement Agent and to appoint additional or other Paying Agents,
Conversion Agents or Replacement Agents, provided that, for so long as the
Convertible Debentures Series 1 are listed on the Luxembourg Stock Exchange, it
will at all times maintain at least one Paying Agent, one Conversion Agent and
one Replacement Agent in Luxembourg and one Paying Agent and one Conversion
Agent having a specified office in one other European city approved by the
Trustee. Notice of any termination or appointment and of any changes in
specified offices will be given to the holders of the Convertible Debentures
Series 1 promptly in accordance with the terms hereof and of the Indenture.

20.      GOVERNING LAW AND JURISDICTION

The Indenture and the Convertible Debentures Series 1 are governed by, and shall
be construed in accordance with, the laws of the Province of Ontario and the
laws of Canada applicable thereto.

              interest is payable on such other Note or Notes and every
              Registered Note issued after the first Interest Payment Date
              for such series in exchange or substitution for, or upon the
              transfer of, the whole or any part of one or more other Notes
              of the same series bearing the same rate of interest and having
              the same Interest Payment Dates and Stated Maturity, shall be
              dated as of the Interest Payment Date next preceding the date
              of certification thereof to which interest has been paid on the
              Notes of such series, unless the date of certification is an
              Interest Payment Date to which interest has been paid, in which
              case it shall be dated as of the date of certification. Every
              Registered Note shall bear interest from its date. Nevertheless
              in the case of any Registered Note issued originally, or upon
              exchange, substitution, transfer or otherwise, if the dating of
              such Note as of the actual date of certification would result
              in the Holder either losing or gaining interest, the Trustee
              shall date such Note such date, other than the actual date of
              certification, as will prevent any such loss or gain, and such
              Note shall bear interest in accordance with the foregoing
              provisions of this section 2.7.

2.8    NOTES TO RANK EQUALLY

The Notes may be issued in such amounts, to such Persons, on such terms not
inconsistent with the provisions of this Indenture, and either at par or at a
discount or at a premium as the Directors may determine. The Notes shall be
direct obligations of the Corporation, shall rank pan passu without
discrimination, preference or priority with one another

                                     -11-

and with other unsecured and unsubordinated indebtedness for borrowed money
of the Corporation. Each Note as soon as issued shall, subject to the terms
hereof, be equally and rateably entitled to the benefits hereof as if all the
Notes had been issued and negotiated simultaneously.

2.9    REGISTRATION OF NOTES

       (a)    The Corporation shall cause to be kept by and at the principal
              office of the Trustee in the city of Calgary a central register
              and, in such other place or places by the Trustee or by such
              other registrar or registrars, if any, as the Corporation with
              the approval of the Trustee may designate, branch registers in
              which shall be entered the names and latest known addresses of
              the Holders of Registered Notes and the other particulars, as
              prescribed by law, of the Notes held by them respectively and
              of all transfers of Registered Notes. Such registration shall
              be noted on the Notes by the Trustee or other registrar.  No
              transfer of a Registered Note shall be effective as against the
              Corporation unless made on one of the appropriate registers by
              the Holder of such Registered Note or his executors or
              administrators or other legal representatives or his or their
              attorney duly appointed by an instrument in form and execution
              satisfactory to the Trustee and upon compliance with such
              requirements as the Trustee or other registrar may prescribe,
              and unless such transfer shall have been duly noted on such
              Note by the Trustee or other registrar.

       (b)    The registers referred to in this section shall at all
              reasonable times be open for inspection by the Corporation, the
              Trustee and any Noteholder.

       (c)    The Holder of a Registered Note may at any time and from time to
              time have such Note transferred at any of the places at which a
              register is kept pursuant to the provisions of this section in
              accordance with such reasonable regulations as the Trustee may
              prescribe.  The Holder of a Registered Note may at any time and
              from time to time have the registration of such Note transferred
              from the register in which the registration thereof appears to
              another register maintained in another place authorized for that
              purpose under the provisions of this Indenture upon payment of a
              reasonable fee to be fixed by the Trustee.

       (d)    Neither the Corporation nor the Trustee nor any registrar shall be
              required to transfetor exchange any Registered Notes on any
              Interest Payment Date or during the 15 Business Days immediately
              preceding any Interest Payment Date.

       (e)    None of the Trustee, any registrar for any of the Registered Notes
              and the Corporation shall be charged with notice of or be bound to
              see to the execution of any trust, whether express, implied or
              constructive, in respect of any Registered Note and may transfer
              any Registered Note on the direction of the Holder thereof,
              whether named as trustee or otherwise, as though that Person were
              the beneficial owner thereof.

       (f)    Except in the case of the central register required to be kept at
              the city of Calgary, the Corporation shall have power at any time
              to close any branch register and in that event it shall transfer
              the records thereof to another existing register or to a new
              register and thereafter such Notes shall be deemed to be
              registered on such existing or new register, as the case may be.
              In the event that the register in any place is closed and the
              records transferred to a register in another place, notice of such
              change shall be given to the Holders of the Registered Notes
              registered in the register so closed and the particulars of such
              change shall be recorded in the central register required to be
              kept in the city of Calgary.

       (g)    Every registrar shall, when requested to do so by the Corporation
              or the Trustee, furnish the Corporation or the Trustee, as the
              case may be, with a list of the names and addresses of the Holders

<PAGE>

                                     -12-

              of Registered Notes showing the principal amounts and serial
              numbers of such Notes held by each Holder.

2.10   PAYMENT OF PRINCIPAL AND INTEREST IN RESPECT OF REGISTERED NOTES

       (a)    As the interest on Registered Notes of any series becomes due
              (except interest payable at Maturity which may be paid upon
              presentation and surrender of such Notes for payment), the
              Corporation, at least three days prior to each date on which
              interest on such Notes becomes due, shall forward or cause to be
              forwarded by first class mail, postage prepaid, (or in the event
              of mail service interruption by such other means as the Trustee
              and the Corporation shall determine to be appropriate) to the
              Holder for the time being at his address appearing on the
              appropriate register hereinbefore mentioned a cheque for such
              interest (less any tax required by law to be deducted) payable to
              the order of such Holder and negotiable at par at each of the
              places at which interest upon such Registered Notes is payable.
              The forwarding of such cheque shall satisfy and discharge the
              liability for the interest on such Registered Notes to the extent
              of the sum represented thereby (plus the amount of any tax
              deducted as aforesaid) unless such cheque is not paid on
              presentation. In the event of the non-receipt of such cheque by
              the Holder or the loss or destruction thereof, the Corporation,
              upon being furnished with evidence of such non-receipt, loss or
              destruction and an indemnity reasonably satisfactory to it, shall
              issue or cause to be issued to such Holder a replacement cheque
              for the amount of such cheque.

       (b)    Where Registered Notes are registered in more than one name, the
              principal and interest from time to time payable in respect
              thereof shall be paid by cheque payable to the order of all such
              Holders, unless the Corporation has received written instructions
              from them to the contrary, and the receipt of any one of such
              Holders therefor shall be a valid discharge to the Trustee, any
              registrar of Notes and the Corporation.

2.11   PAYMENT OF PRINCIPAL AND INTEREST IN RESPECT OF BEARER NOTES

       (a)    Interest payments in respect of Bearer Notes of any series shall
              be made (less any tax required by law to be deducted) against
              presentation and surrender of the appropriate Coupons at the place
              or places specified with respect to such series.

       (b)    Any payment of principal in respect of a Bearer Note shall be made
              against presentation and surrender of such Bearer Note, together
              with all unmatured Coupons (if any) appertaining thereto, failing
              which the amount of the missing unmatured Coupons will be deducted
              from the principal amount due for payment, at the place or places
              specified with respect to such series. Amounts of principal so
              deducted will be paid against surrender of the relevant missing
              Coupons within a period of six years from the date upon which such
              amount would otherwise have been payable.

       (c)    Interest payable in respect of any interest payment which is in
              default shall be paid to the Holder of the Coupon representing
              such interest payment and interest payable in respect of any other
              amount in default shall be paid to the Holder of the Bearer Note
              in respect of which such payment is due.

2.12   OWNERSHIP OF REGISTERED NOTES

       (a)    The Person in whose name any Registered Note shall be registered
              shall be deemed to be the owner thereof for all purposes of this
              Indenture and payment of or on account of the principal of and
              interest on such Registered Note shall be made only to or upon the
              order in writing of the Holder thereof and such payment shall be a
              complete discharge to the Trustee, any registrar of Notes, the
              Corporation and any Paying Agent for the amounts so paid.

<PAGE>

                                     -13-

       (b)    The Holder for the time being of any Registered Note shall be
              entitled to the principal, interest and premium, if any, evidenced
              by such Registered Note, free from all equities or rights of
              set-off or counterclaim between the Corporation and the original
              or any intermediate Holder thereof (except any equities of which
              the Corporation is required to take notice by law) and all Persons
              may act accordingly and a transferee of a Registered Note shall,
              after the appropriate form of transfer is lodged with the Trustee
              or other registrar of Notes and upon compliance with all other
              conditions in that behalf required by this Indenture or by any
              conditions contained in such Registered Note or by law, be
              entitled to be entered on the appropriate register or on any one
              of the appropriate registers as the owner of such Registered Note
              free from all equities or rights of set-off or counterclaim
              between the Corporation and his transferor or any previous Holder
              thereof, save in respect of equities of which the Corporation is
              required to take notice by law.

2.L3   NEGOTIABILITY AND OWNERSHIP OF BEARER NOTES AND COUPONS

       (a)    Bearer Notes and Coupons shall be negotiable and title thereto
              shall pass by delivery.

       (b)    Except as may be ordered by a court of competent jurisdiction or
              as required by law, the Corporation and the Trustee may deem and
              treat the bearer of any Bearer Note or Coupon as the absolute
              owner thereof for all purposes and none of the Corporation, the
              Trustee or any Paying Agent shall be affected by any notice to the
              contrary.

       (c)    The Holder of any Bearer Note and the bearer of any Coupon shall
              be entitled to the principal, interest or premium, if any,
              evidenced by such instrument free from all equities or rights of
              set-off or counterclaim between the Corporation and the original
              or any intermediate or subsequent Holder or bearer thereof(except
              any equities of which the Corporation is required to take notice
              of by law) and all persons may act accordingly and the receipt of
              any such Holder or bearer for any such principal or interest shall
              be a complete discharge to the Corporation and the Trustee for the
              same and none of the Corporation, the Trustee or any Paying Agent
              shall be bound to inquire into the title of any such Holder or
              bearer.

2.14   EXCHANGE OF NOTES

       (a)    Bearer Notes may be exchanged for Registered Notes and Registered
              Notes may be exchanged for Bearer Notes (provided, in either case,
              that such Notes are issuable), and Notes of any denomination may
              be exchanged for Notes of any other authorized denomination or
              denominations, any such exchange to be for Notes of an equivalent
              aggregate principal amount of Notes of the same series, carrying
              the same rate of interest and having the same Stated Maturity and
              the same redemption and sinking fund provisions, if any. Exchanges
              of Notes may be made at the principal offices of the Trustee in
              the city of Calgary. Any Notes tendered for exchange shall be
              surrendered to the Trustee and shall be cancelled. The Corporation
              shall execute, and the Trustee shall certify, all Notes necessary
              to carry out such exchanges.

       (b)    Except as otherwise provided herein, upon any exchange of Bearer
              Notes for Registered Notes or Registered Notes for Bearer Notes or
              Notes of any denomination for Notes of any other authorized
              denominations and upon any transfer of Registered Notes, the
              Trustee or other registrar of Notes may make a sufficient charge
              to reimburse it for any stamp tax, security transfer tax or other
              governmental charge required to be paid, and in addition a
              reasonable charge for its services for each Note exchanged or
              transferred, and payment of such charges shall be made by the
              party requesting such exchange or transfer as a condition
              precedent thereto.

       (c)    Notwithstanding the foregoing, no charge (other than for insurance
              on any Notes forwarded by mail) shall be made by the Trustee, any
              registrar of Notes or the Corporation (i) for any exchange,

<PAGE>
                                     -14-

              registration or transfer of any Note applied for within a period
              of 30 days from the date hereof; or (ii) for any exchange, after
              such period, of Notes for Notes in lesser denominations; or (iii)
              for Convertible Debentures, provided that the Notes surrendered
              for exchange shall not have been issued as a result of any
              previous exchange, other than an exchange pursuant to clause (i)
              of this subsection or section 3.7.

       (d)    Bearer Notes surrendered for exchange shall be accompanied by all
              unmatured Coupons appertaining thereto and Bearer Notes issued on
              an exchange shall have detached therefrom and cancelled all
              Coupons appertaining thereto which have matured and in respect of
              which the interest has been paid. Each Note delivered under this
              Indenture in exchange for or in lieu of any other Note shall carry
              the rights to principal and interest accrued and unpaid, and to
              accrue, which were carried by such other Note.

       (e)    Neither the Corporation, the Trustee nor any other registrar of
              Notes shall be required to make exchanges of Notes on any Interest
              Payment Date or during the 15 Business Days immediately preceding
              any Interest Payment Date.

2.15   REPLACEMENT OF NOTES AND COUPONS

If any of the Notes or Coupons shall become mutilated or be lost, stolen or
destroyed and in the absence of notice that such Notes have been acquired by a
bona fide purchaser within the meaning of the BUSINESS CORPORATIONS ACT (Yukon),
the Corporation in its discretion may issue, and thereupon the Trustee shall
certify and deliver, a new Note or Coupon upon surrender and cancellation of the
mutilated Note or Coupon, or, in the case of a lost, stolen or destroyed Note or
Coupon, in lieu of and in substitution for the same, and the substituted Note or
Coupon shall be in a form approved by the Trustee and shall be entitled to the
benefits of this Indenture equally with all other Notes or Coupons issued or to
be issued hereunder. Each Note delivered under this Indenture in exchange for
or in lieu of any other Note shall carry the rights to principal and interest
accrued and unpaid, and to accrue, which were carried by such other Note. In
case of loss, theft or destruction the applicant for a new Note or Coupon shall
furnish to the Corporation and to the Trustee such evidence of such loss, theft
or destruction as shall be satisfactory to them in their discretion and shall
also furnish an indemnity in amount and form satisfactory to them in their
discretion. The applicant shall pay all expenses incidental to the issuance of
any such new Note or Coupon.

2.16   INTERIM NOTES

Pending delivery to the Trustee of definitive Notes of any series or part of a
series, the Corporation may execute in lieu thereof (but subject to the same
provisions, conditions and limitations), and the Trustee may certify, interim
printed, mimeographed or typewritten Notes, in such form and in such
denominations as may be approved by the Trustee and the Chairman, the President
or a Vice President of the Corporation (whose certification or signature, either
manual or in facsimile, as the case may be, on any such interim Notes shall be
conclusive evidence of such approval) entitling the Holders thereof to
definitive Notes of such series or part of a series in any authorized
denominations when the same are ready for delivery, without expense to such
Holders, but the total amount of interim Notes of any series or part of a series
so issued shall not exceed the aggregate principal amount of Notes of such
series or part of a series for the time being authorized. Forthwith after the
issuance of any such interim Notes the Corporation shall cause to be prepared
the appropriate definitive Notes for delivery to the Holders of such interim
Notes.

Interim Notes which have been duly issued shall, until exchanged for definitive
Notes, entitle the Holders thereof to rank for all purposes as Noteholders and
otherwise in respect of this Indenture to the same extent and in the same manner
as though such exchange had actually been made. When exchanged for definitive
Notes such interim Notes shall forthwith be cancelled by the Trustee. Any
interest paid upon interim Notes shall be noted thereon by the Paying Agent at
the time of payment unless paid by cheque to the Holders thereof.

2.17   OPTION OF HOLDER AS TO PLACE OF PAYMENT

Except as otherwise provided herein, all sums which may at any time become
payable, whether at Maturity, upon retraction of Escrowed Subscription Funds,
on a declaration by the Trustee pursuant to section 6.3 or on redemption or
otherwise, on account of any Note or Coupon or any principal, interest or
premium shall be payable at the option of the Holder or the bearer thereof at
any of the places at which the principal of and interest or premium (if any)
on such Note or Coupon are payable.

2.18   PAYMENT AGREEMENTS FOR NOTES

Notwithstanding anything contained herein, the Corporation may enter into an
agreement with the Holder of a Registered Note or with the Person for whom
such Holder is acting as nominee providing for the payment to such Holder of
the principal of and interest or premium (if any) on such Note at a place or
places other than the place or places specified herein or any supplemental
indenture and in such Note as the place or places for such payment.  Any
payment of the principal of and interest or premium (if any) on any such
Registered Note at such other place or places pursuant to such agreement
shall, notwithstanding any other provision of this Indenture or any
supplemental indenture, be valid and binding on the Corporation, the Trustee
and the Holders of Notes.

                                     ARTICLE 3
               REDEMPTION AND PURCHASE FOR CANCELLATION OF THE NOTES

3.1    GENERAL

The Corporation, when not in default hereunder, shall have the right at its
option to redeem, either in whole at any time or in part from time to time
before Maturity, Notes issued hereunder of any series or part of a series
which by their terms are made so redeemable at such rate or rates of premium,
if any, and at such date or dates and on such terms and conditions as shall
have been determined at the time of the issue of such Notes and as shall be
expressed in this Indenture and/or in the Notes and/or in the supplemental
indenture authorizing or providing for the issue thereof.

"Premium" as used in this Article 3 with reference to any Note shall mean the
excess of the then applicable redemption price of such Note (excluding
interest) over the principal amount of such Note.

3.2    NOTICE OF REDEMPTION

Notice of intention to redeem any Note shall be given by or on behalf of the
Corporation to the Holders of the Note which are to be redeemed, not more
than 60 days nor less than 30 days prior to the date fixed for redemption, in
the manner provided in section 10.2 hereof.  Every notice of redemption shall
designate the series and Stated Maturity of the Notes so called for
redemption, and unless all of the Notes or all of the Notes of a series or
all of the Notes of one Stated Maturity so designated for the time being
outstanding are to be redeemed, state the designating numbers of the Notes so
called for redemption and in case a Note is to be redeemed in part only that
part of the principal amount thereof so to be redeemed, and shall specify the
redemption date, the redemption price and the place or places of payment and
shall state that all interest thereon shall cease from and after the said
date.

3.3    NOTES DUE ON REDEMPTION DATES

Notice having been given as aforesaid, all the Notes so called for redemption
shall thereupon become due and payable at the redemption price, on the
redemption date specified in such notice, at any of the places where the
principal of such Notes is expressed to be payable in the same manner and
with the same effect as if it were the Stated Maturity specified in such
Notes respectively, anything therein or herein to the contrary
notwithstanding, and from and after such redemption date, if the moneys
necessary to redeem such Notes shall have been deposited as provided in
section

<PAGE>

                                     -16-

3.4 and the Trustee shall have been furnished with affidavits or
other proof satisfactory to it as to the publication and/or mailing of such
notices, interest on the said Notes shall cease and Coupons for interest to
accrue after such redemption date on said Notes shall become and be void.

In case any question shall arise whether any notice has been given as above
provided and such deposit made, such question shall be decided by the Trustee
whose decision shall be final and binding upon all parties in interest.

3.4    DEPOSIT OF REDEMPTION MONIES

Such redemption shall be provided for by the Corporation irrevocably
depositing with the Trustee or any Paying Agent to the order of the Trustee
in trust for the Holders of the Notes called for redemption, before the
redemption date specified in such notice, such sums as may be sufficient to
pay the redemption price of such Notes including accrued interest and
premium, if any, on the Notes so called for redemption to the date fixed for
redemption.  The Corporation shall also deposit with the Trustee if required
by it a sum sufficient to pay any charges or expenses which may be incurred
by the Trustee in connection with such redemption. From the sums so deposited
the Trustee shall pay or cause to be paid to the Holders of such Notes so
called for redemption, upon surrender of such Notes with all unmatured
Coupons, if any, appertaining thereto (or without such surrender if the
registered Holder of the Notes to be redeemed or the person for whom such
registered Holder is acting as nominee has entered into an agreement with the
Corporation to that effect) the principal, interest and premium, if any, to
which they are respectively entitled on redemption. Provided that in the case
of Bearer Notes the accrued interest as represented by Coupons matured prior
to, or on, the redemption date shall continue to be payable (but without
interest thereon, unless the Corporation shall make default in the payment
thereof upon demand) to the respective bearers of such Coupons upon
presentation and surrender thereof.

3.5    CANCELLATION AND DESTRUCTION OF NOTES AND COUPONS

All Notes surrendered for cancellation upon any redemption under this
Article, together with the unmatured Coupons, if any, thereto appertaining,
shall forthwith be delivered to the Trustee and shall be cancelled by it and
no Notes shall be issued in substitution therefor.

All Notes and Coupons which shall have been delivered to and cancelled by the
Trustee shall be destroyed by the Trustee and if required by the Corporation
the Trustee shall furnish to it a destruction certificate setting out the
designating numbers and denominations of the Notes so destroyed.

3.6    SURRENDER OF NOTES FOR CANCELLATION

If the principal moneys of Notes issued hereunder shall become payable by
redemption or otherwise before the Stated Maturity thereof; the person
presenting such Note for payment must surrender the same for cancellation
together with all unmatured Coupons, if any, appertaining thereto, the
Corporation nevertheless paying the interest accrued and unpaid thereon if
the date fixed for payment be not an Interest Payment Date.

3.7    PURCHASE OF NOTES FOR CANCELLATION

At any time when the Corporation is not in default hereunder it may purchase
all or any of the Notes in the market (which shall include purchase from or
through an investment dealer or a firm holding membership on a recognized
stock exchange) or by invitation for tenders or by private contract and, in
each case, at any price. All Notes so purchased, together with the unmatured
Coupons (if any) appertaining thereto, shall forthwith be delivered to the
Trustee and shall be cancelled by it and, except as hereinafter provided, no
Notes shall be issued in substitution therefor.

If and upon an invitation for tenders, more Notes are tendered at the same
lowest price that the Corporation is prepared to accept, the Notes to be
purchased by the Corporation shall be selected by the Trustee by lot, or in
such other manner

<PAGE>

                                     -17-

as the Trustee may consider equitable, from the Notes tendered by each
Noteholder who tendered at such lowest price. For this purpose the Trustee
may make, and from time to time amend, regulations with respect to the manner
in which Notes may be so selected and regulations so made shall be valid and
binding upon all Noteholders, notwithstanding the fact that, as a result
thereof, one or more of such Notes become subject to purchase in part only.
The Holder of any Note of which a part only is purchased, upon surrender of
such Note for payment, shall be entitled to receive, without expense to such
Holder, one or more new Notes for the unpurchased part so surrendered and the
Trustee shall certify and deliver such new Note or Notes upon receipt of the
Note so surrendered.

4.1    EXERCISE OFFICES

In connection with the exchange of Note Certificates and exercise of Special
Notes and compliance with such other terms and conditions hereof as may be
required, the offices at which Note Certificates may be surrendered for
exchange or transfer or at which Special Notes may be exercised for

of each series of Notes. The Corporation may from time to time designate
alternate or additional places as the Exercise Offices and shall give notice
to the Trustee of any change of the Exercise Offices.

4.2    ADMINISTRATION OF ESCROWED SUBSCRIPTION FUNDS

All Escrowed Subscription Funds shall be held at or administered through the
principal office of the Trustee at Calgary, Alberta. The Trustee shall not be
entitled to deal with the Escrowed Subscription Funds except in accordance
with the terms of this Indenture. In the event that the Trustee determines
the necessity for the approval by the Noteholders of any matter, an
extraordinary resolution of the Noteholders shall provide sufficient
authority upon which the Trustee may act and the Trustee shall not be
responsible for any loss occasioned by so doing.

presentation and surrender of the several Coupons for such interest
instalments as are evidenced thereby as they severally mature.

5.2    MAINTENANCE OF CORPORATE EXISTENCE

Except as herein otherwise expressly provided, the Corporation will at all
times maintain, preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises and the Corporation
will carry on and conduct or will cause to be carried on and conducted its
business and the business of its Subsidiaries in a proper and efficient
manner and will keep or cause to be kept proper books of account and make or
cause to be made therein true and accurate entries of all its dealings and
transactions in relation to its business and the business of its
Subsidiaries, as the case may be, all in accordance with Generally Accepted
Accounting Principles, and at all reasonable times it will furnish or cause
to be furnished to the Trustee or its duly authorized agent or attorney such
information relating to its business and that of its Subsidiaries as the
Trustee may reasonable require and such books of account shall at all
reasonable times be open for inspection by the Trustee or such agent or
attorney.

The Corporation will furnish to the Trustee a copy of all financial statements,
whether annual or interim, of the Corporation and the report, if any, of the
Corporation's auditors thereon and of all annual and other regular periodic

they are furnished to such shareholders.  The Corporation will cause the
consolidated financial statements of the Corporation and its Subsidiaries to be

services as Trustee hereunder and will repay to the Trustee on demand all moneys
which shall have been paid by the Trustee in and about the execution of the
trusts hereby created with interest at 6% per annum from 30 days after the date
of the invoice from the Trustee to the Corporation in respect of such
expenditure until repayment, and such moneys and the interest thereon, including
the Trustee's remuneration, shall be payable out of any funds coming into the
possession of the Trustee in priority to any of the Notes or interest thereon.
The said remuneration shall continue to be payable until the trusts hereof be
finally wound up and whether or not the trusts of this Indenture shall be in the
course of administration by or under the direction of the court.

5.5    MAINTENANCE OF OFFICE OR AGENCY

If the Notes of a series are issuable only as Registered Notes, the Corporation
will maintain in each Place of Payment for such Notes an office or agency where
Notes of that series may be presented or surrendered for payment, where Notes of
that series may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Corporation in respect of the Notes of
that series and this Indenture may be served.

If Notes of a series are issuable as Bearer Notes, the Corporation will
maintain:

       (a)    in the city of Calgary, an office or agency where any Registered
              Notes of that series may be presented or surrendered for payment,
              where any Registered Notes of that series may be surrendered for
              registration of transfer, where Notes of that series may be
              surrendered for exchange, where notices and demands to or upon the
              Corporation in respect of the Notes of that series and this
              Indenture may be served and where Bearer Notes ofthat series and
              related Coupons may be presented or surrendered for payment in the
              circumstances described in the following paragraph (and not
              otherwise);

       (b)    subject to any laws or regulations applicable thereto, in a Place
              of Payment for that series which is located outside Canada, an
              office or agency where Notes of that series and relatedCoupons may
              be presented or surrendered for payment; provided, however, that,
              if the Notes of that series are listed on any stock exchange
              located outside Canada and such stock exchange shall so require,
              the Corporation will maintain a Paying Agent for the Notes of that
              series in any required city located outside Canada so long as the
              Notes of that series are listed on such exchange; and

       (c)    subject to any laws or regulations applicable thereto, in a Place
              of Payment for that series located outside Canada, an office or
              agency where any Registered Notes of that series may be
              surrendered for registration of transfer, where Notes of that
              series may be surrendered for exchange and where notices and
              demands to or upon the Corporation in respect of the Notes of that
              series and this Indenture may be served.  The Corporation will
              give prompt written notice to the Trustee of the location, and any
              change in the location, of such office or agency.  If at any time
              the Corporation shall fail to maintain any such required office or
              agency or shall fail to furnish the Trustee with the address
              thereof; such presentations, surrenders, notices and demands may
              be made or served at the principal office of the Trustee in the
              city of Calgary, except that Bearer Notes of that series and the

<PAGE>

                                     - 19 -


              related Coupons may be presented and surrendered for payment at
              the offices specified in the Note, and the Corporation hereby
              appoints the same as its agent to receive such respective
              presentations, surrenders, notices and demands.

The Corporation may also from time to time designate one or more other
offices or agencies where the Notes of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Corporation of its obligation to maintain an
office or agency in accordance with the requirements set forth above for
Notes of any series for such purposes.  The Corporation will give prompt
written notice to the Trustee of any such designation or rescission and of
any change in the location of any such other office or agency.  Unless
otherwise specified with respect to any Notes as contemplated by section 2.2
with respect to a series of Notes, the Corporation hereby designates as a
Place of Payment for each series of Notes the principal office of the Trustee
in the city of Calgary, and initially appoints the Trustee at its principal
office as Paying Agent in such city and as its agent to receive all such
presentations, surrenders, notices and demands.

5.6    MONEY FOR NOTES PAYMENTS TO BE HELD IN TRUST

If the Corporation shall at any time act as its own Paying Agent with respect
to any series of Notes and any related Coupons, it will, on or before each
due date of the principal of (and premium, if any) or interest on any of the
Notes of that series, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum in the currency in which the Notes of such
series are payable (except as otherwise specified pursuant to section 2.2 for
the Notes of such series) sufficient to pay the principal (and premium, if
any) or interest so becoming due until such sums shall be paid to such
Persons or otherwise disposed of as herein provided and will promptly notify
the Trustee of its action or failure to so act.

Whenever the Corporation shall have one or more Paying Agents for any series
of Notes and any related Coupons, it will, prior to or on each due date of
the principal of (and premium, if any) or interest on any Notes ofthat series,
deposit with a Paying Agent a sum (in the currency described in the preceding
paragraph) sufficient to pay the principal (and premium, if any) or interest
so becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying
Agent is the Trustee) the Corporation will promptly notify the Trustee of its
action or failure to so act.

The Corporation will cause each Paying Agent (other than the Trustee) for any
series of Notes to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee, subject to the provisions of
this section, that such Paying Agent will:

       (a)    hold all sums held by it for the payment of the principal of (and
              premium, if any) and interest on securities of such series (where
              such sums have been paid to it by the Corporation or by any other
              obligor on the Notes) in trust for the benefit of the Persons
              entitled thereto until such sums shall be paid to such Persons or
              otherwise disposed of as herein provided;

       (b)    give the Trustee notice of any default by the Corporation (or any
              other obligor upon the securities of such series) in the making of
              any payment of principal of (or premium, if any) or interest on
              the Notes of such series; and

       (c)    at any time during the continuance of such default, upon the
              written request of the Trustee, forthwith pay to the Trustee all
              sums so held in trust by such Paying Agent.

The Corporation may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Written
Order of the Corporation direct any Paying Agent to pay, to the Trustee all sums
held in trust by the Corporation or such Paying Agent, such sum to be held by
the Trustee upon the same trusts as

<PAGE>
                                     - 20 -

those upon which sums were held by the Corporation or such Paying Agent; and,
upon such payment by any Paying Agent to the Trustee, such Paying Agent shall
be released from all further liability with respect to such sums.

Except as provided in the Notes of any series, any money deposited with the
Trustee or any Paying Agent, or then held by the Corporation, in trust for the
payment of the principal of (and premium, if any) or interest on any Note of any
series and remaining unclaimed for two years after such principal (and premium,
if any) or interest have become due and payable shall be paid to the Corporation
on Written Request of the Corporation, or (if then held by the Corporation)
shall be discharged from such trust; and the Holder of such Note shall
thereafter, as an unsecured general creditor, look only to the Corporation for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Corporation as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Corporation cause to be published once, in an Authorized
Newspaper, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Corporation.

5.7    STATEMENT AS TO COMPLIANCE

The Corporation covenants that, on or before December 31, 1998, and on or before
December 31 in each subsequent year and at any other time if requested by the
Trustee, the Corporation will furnish to the Trustee a Certificate of the
Corporation stating that the Corporation has performed its obligations under and
complied with all covenants, conditions and other requirements contained in this
Indenture, non-compliance with which would, with the giving of notice or the
lapse of time or both, constitute an Event of Default hereunder or, if such is
not the case, specifying the covenant, condition or other requirement which has
not been complied with and giving particulars of such non-compliance and the
action, if any, the Corporation proposes to take with respect thereto. If the
officer signing the Certificate of the Corporation knows of such an Event of
Default, whether then existing or occurring during such preceding fiscal year,
the Certificate of the Corporation shall describe such Event of Default and its
status with particularity.  The Corporation shall also promptly notify the
Trustee if the Company's fiscal year is changed so that the end thereof is on
any date other than the then current fiscal year end date.  For purposes of this
section, such compliance shall be determined without regard to any period of
grace granted by the Trustee or requirement of notice under this Indenture.  The
Corporation will deliver to the Trustee, forthwith upon becoming aware of any
default in the performance or observance of any covenant, agreement or condition
contained in this Indenture, or any Event of Default, a Certificate of the
Corporation specifying with particularity such Event of Default and further
stating what action the Corporation has taken or is taking or proposes to take
with respect thereto.

5.8    ADDITIONAL AMOUNTS

If any Notes of a series provide for the payment of additional amounts to any
Holder in respect of any tax, assessment or governmental charge ("Additional
Amounts"), the Corporation will pay to the Holder of any Note of such series or
any Coupon appertaining thereto such Additional Amounts as may be specified as
contemplated by section 2.2.  Whenever in this Indenture there is mentioned, in
any context, the payment of the principal of or any premium or interest on, or
in respect of, any Note of a series or payment of any related Coupon or the net
proceeds received on the sale or exchange of any Note of a series, such mention
shall be deemed to include mention of the payment of Additional Amounts provided
for by the terms of such series established pursuant to section 2.2 to the
extent that, in such context, Additional Amounts are, were or would be payable
in respect thereof pursuant to such terms and express mention of the payment of
Additional Amounts (if applicable) in any provisions hereof shall not be
construed as excluding Additional Amounts in those provisions hereof where such
express mention is not made.

Except as otherwise specified as contemplated by section 2.2, if the Notes of a
series provide for the payment of Additional Amounts, at least 10 days prior to
the first Interest Payment Date with respect to that series of Notes (or if the
Notes of that series will not bear interest prior to Maturity, the first day on
which a payment of principal and any premium is made), and at least 10 days
prior to each date of payment of principal and any premium or interest if there
has been any change with respect to the matters set forth in the below-mentioned
Certificate of the

<PAGE>

                                     - 21 -


Corporation, the Corporation will furnish the Trustee and the Corporation's
principal Paying Agent or Paying Agents, if other than the Trustee, with a
Certificate of the Corporation instructing the Trustee and such Paying Agent
or Paying Agents whether such payment of principal of and any premium of
interest on the Notes of that series shall be made to the Holders of Notes of
that series or any related Coupons without withholding for or on account of
any tax, assessment or other governmental charge described in the Notes of
the series.  If any such withholding shall be required, then such Certificate
of the Corporation shall specify by country the amount, if any, required to
be withheld on such payments to such Holders of Notes of that series or
related Coupons and the Corporation will pay to the Trustee or such Paying
Agent the Additional Amounts required by the terms of such Notes. In the
event that the Trustee or any Paying Agent, as the case may be, shall not so
receive the above-mentioned certificate, then the Trustee or such Paying
Agent shall be entitled to (i) assume that no such withholding or deduction
is required with respect to any payment of principal or interest with respect
to any Notes of a series or related Coupons until it shall have received a
certificate advising otherwise and (ii) to make all payments of principal and
interest with respect to the Notes of a series or related Coupons without
withholding or deductions until otherwise advised.  The Corporation covenants
to indemnify the Trustee and any Paying Agent for, and to hold them harmless
against, any loss, liability or expense reasonably incurred without
negligence or bad faith on their part arising out of or in connection with
actions taken or omitted by any of them in reliance on any Certificate of the
Corporation furnished pursuant to this section.

5.9    LONG TERM DEBT AND TANGIBLE ASSETS

The Corporation will, so long as any Special Notes are outstanding, maintain
Tangible Assets equal to or greater than 140% of Long Term Debt at all times
including after redemption of any redeemable preference shares of the
Corporation or any Subsidiary.  This ratio shall be calculated no later than
the 135th day following the end of each of the Corporation'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.

5.10   LIMITATION UPON CREDIT FACILITY AND REPAYMENTS

The Corporation will not, so long as any Special Notes are outstanding:

       (a)    have outstanding more than US.$12,000,000 under the EnCap Credit
              Facility for the period commencing 30 days from the date hereof;
              and

       (b)    use any of the net proceeds from the issuance of the Notes to
              reduce the Corporation's existing indebtedness.

5.11   WAIVER OF CERTAIN COVENANTS

The Corporation may omit in any particular instances to comply with any term,
provision or condition set forth in section 5.10, if the Holders of Notes
outstanding, by Extraordinary Resolution, waive such compliance in such
instances with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the
obligations of the Corporation and the duties of the Trustee in respect of
any such term, provision or condition shall remain in full force and effect.

5.12   PAYMENT OF TAXES AND OTHER CLAIMS

The Corporation will pay or discharge or cause to be paid or discharged, before
the same shall become delinquent, (a) all taxes, assessments and governmental
charges levied or imposed upon the Corporation or any Subsidiary or upon the
income, profits or property of the Corporation or any Subsidiary and (b) all
lawful claims for labour, materials and supplies which, if unpaid, might by law
become a Lien upon the property of the Corporation or any Subsidiary; PROVIDED,
HOWEVER, that the Corporation shall not be required to pay or discharge or cause
to be paid or discharged

<PAGE>

                                     - 22 -


any such tax, assessment, charge or claim whose amount, applicability or
validity is being contested in good faith by appropriate proceedings.

5.13   MAINTENANCE OF PROPERTIES

The Corporation will cause all properties owned by the Corporation or any
Subsidiary or used or held for use in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order (ordinary wear and tear excepted) and supplied with all
necessary equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Corporation may be necessary so that the business carried on in connection
therewith may be conducted at all times; PROVIDED, HOWEVER, that nothing in this
section shall prevent the Corporation from discontinuing the maintenance of any
of such properties if such discontinuance is, in the judgment of the
Corporation, desirable in the conduct of its business or the business of any
Subsidiary and not disadvantageous in any material respect to the Noteholders.

5.14   INSURANCE

The Corporation will at all times keep all of the Corporation's and its
Subsidiaries' properties which are of an insurable nature insured with insurers,
believed by the Corporation to be responsible, against loss or damage to the
extent that property ofsimilar character is usually so insured by corporations
similarly situated and owning like properties in similar geographic areas in
which the Corporation or each such Subsidiary operates; provided that such
insurance is generally available at commercially reasonable rates, and provided
further that the Corporation or such Subsidiary may self-insure directly or
through captive insurers or insurance cooperatives, to the extent that the
Corporation determines that such practice is consistent with prudent business
practices. Such insurance shall be in such amount, on such terms, in such forms
and for such periods as are customary for similarly situated Persons in the
Corporation's industry or in insurance markets available to the Corporation.

5.15   RESTRICTIONS ON CHARTER AMENDMENTS

The Corporation will not amend its Memorandum and Articles of Association except
as required by law or except to the extent that such amendment would not have a
material adverse effect on (a) the ability of the Corporation to perform its
obligations under this Indenture or the Notes or (b) the rights of the
Noteholders, except that neither (i) increases in the number of common shares
and issuance thereof with related securities, nor (ii) designations of preferred
stock of the Company, modifications of the terms of such designations and
issuance thereof with related securities, nor (iii) modification or expansion of
the indemnity provisions provided by the Corporation to its directors and
officers, nor (iv) change of the Corporation's registered agent shall be deemed
an amendment hereunder.

5.16   CANADIAN WITHHOLDING AND REPORTING REQUIREMENTS

To the extent permitted by law, the Corporation will provide to the Trustee, the
Paying Agent or to any Noteholder such statements, certificates or other
documentation concerning the organization or operations of the Corporation as
may be reasonably necessary to establish any exceptions or exemptions from
Canadian federal income tax withholding and reporting requirements.

5.17   MAINTENANCE OF LISTINGS FOR COMMON SHARES AND NOTES

While any Note remains outstanding, the Corporation will maintain a listing for
its common shares on a nationally recognized stock exchange in Canada or the
United States.

5.18   TRUSTEE MAY PERFORM COVENANTS

If the Corporation shall fail to perform any of its covenants contained herein,
the Trustee may in its discretion, but (subject to section 6.3) need not, notify
the Noteholders of such failure or may itself perform any of such covenants

<PAGE>

                                     - 23 -


capable of being performed by it and, if any such covenant requires the payment
of money, it may make such payment with its own funds, or with money borrowed by
it for such purpose, but shall be under no obligation to perform such covenants
or to make any such payments with its own funds or with money borrowed by it;
and all sums so paid shall be payable by the Corporation in accordance with the
provisions of section 5.4.  No such performance by the Trustee of any covenant
contained herein or payment by the Corporation of any sums advanced or borrowed
by the Trustee pursuant to the foregoing provisions shall be deemed to relieve
the Corporation from any default hereunder.


                                   ARTICLE 6
                                   REMEDIES

6.1    EVENTS OF DEFAULT

"Event of Default", wherever used herein with respect to Notes of any series,
means any one of the following events (whatever the reason for such Event of
Default and whether it shall be voluntary or involuntary or be effected by
operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of and administrative or governmental body):

       (a)    default in the payment of any interest upon any Note of that
              series, or any related Coupon, when such interest or Coupon
              becomes due and payable, and continuance of such default for a
              period of 7 days; or

       (b)    default in the payment of the principal of (or premium, if any,
              on) any Note of that series as and when it shall become due and
              payable at its Maturity, upon redemption, by declaration or
              otherwise; or

       (c)    default in the performance, or breach, of any covenant or warranty
              of the Corporation in this Indenture (other than a covenant or
              warranty a default in performance of which or breach of which is
              elsewhere in this section specifically dealt with or which has
              expressly been included in this Indenture solely for the benefit

              outstanding for more than 60 calendar days from the date of its

       (h)    if the Issuer or any Material Subsidiary shall generally fail to

              Issuer or such Material Subsidiary, as the case may be, may
              contest in good faith generally) or shall be declared or
              adjudicated by a competent court to be insolvent or bankrupt,
              shall consent to an entry of an order of relief against it in an
              involuntary bankruptcy case, shall enter into any assignment or
              other similar arrangement for the benefit of its creditors or

              such documents is false in any material respect when made and
              (except where the Trustee shall have certified to the Issuer that
              it considers such falsity to be incapable of remedy, in which case
              no such notice or continuation as is hereinafter mentioned will be
              required) such falsity continues for a period of 30 calendar days
              (or such longer period as the Trustee may in its absolute
              discretion permit) next following the service by the Trustee on
              the Issuer of notice requiring the same to be remedied;

       (j)    or any other Event of Default provided with respect to Notes of
              that series.

6.2    NOTICE OF EVENTS OF DEFAULT

The Corporation shall, within 30 days after it becomes aware that an Event of
Default has occurred, notify the Trustee of the occurrence of such Event of
Default and upon receipt of such notice and if the Event of Default is
continuing the Trustee shall, within 30 days after it becomes aware of the
occurrence of such Event of Default, give notice thereof to the Noteholders,
provided that, notwithstanding the foregoing, the Trustee shall not be
required to give such notice if the Trustee in good faith shall have decided
that the withholding of such notice is in the best interests of the
Noteholders and shall have so advised the Corporation in writing. Where
notice of the occurrence of an Event of Default has been given and the Event
of Default is thereafter cured, notice that the Event of Default is no longer
continuing shall be given by the Trustee to the Noteholders within 30 days
after the Trustee becomes aware that the Event of Default has been cured.

6.3    ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT

If an Event of Default described in clause (a), (b) or (j) of section 6.1 with
respect to Notes of any series at the time outstanding occurs and is continuing,
then in every such case the Trustee or the Holders of not less than 25% in
principal amount of the outstanding Notes of that series may declare the
principal amount of all the Notes of that series to be due and payable
immediately, by a notice in writing to the Corporation (and to the Trustee if
given by Holders), and upon any such declaration such principal amount (or
specified portion thereof) shall become immediately due and payable.  If an
Event of Default described in clause (c), (d), (e), (f), (g), (h) or (i) of
section 6.1 occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of all the Notes then
outstanding may declare the principal amount of all the outstanding Notes to be
due and payable immediately, by a notice in writing to the Corporation (and to
the Trustee if given by the Holders) and upon any such declaration such
principal amount (or specified portion thereof) shall become immediately due and
payable.

At any time after such a declaration of acceleration with respect to Notes of
any series (or of all series, as the case may be) has been made and before a
judgment or decree for payment of the money due has been obtained by the Trustee
as hereinafter in this Article provided, the Holders of the outstanding Notes of
that series (or of all series, as the case may be), by Extraordinary Resolution,
may rescind and annul such declaration and its consequences if:

       (a)    the Corporation has paid or deposited with the Trustee a sum
              sufficient to pay in the currency in which the Notes of such
              series are payable (except as otherwise specified pursuant to
              section 2.2 for the Notes of such series):

              (i)    all overdue interest on all outstanding Notes of that
                     series (or of all series, as the case may be) and any
                     related Coupons,

              (ii)   all unpaid principal of (and premium, if any, on) any
                     outstanding Notes of that series (or of all series, as the
                     case may be) which has become due otherwise than by such
                     declaration of acceleration, and interest on such unpaid
                     principal at the rate or rates prescribed therefor in such
                     Notes,

              (iii)  interest upon overdue interest at the rate or rates
                     prescribed therefor in such Notes, and

              (iv)   all sums paid or advanced by the Trustee hereunder and the
                     reasonable compensation, expenses, disbursements and
                     advances of the Trustee, its agents and counsel and any
                     sales, value-added or goods and services tax thereon; and

       (b)    all Events of Default with respect to Notes of that series (or of
              all series, as the case may be), other than the non-payment of
              amounts of principal of (or premium, if any) or interest on Notes
              of that series (or of all series, as the case may be) which have
              become due solely by such declaration of acceleration, have been
              cured or waived as provided in section 6.14.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

6.4    COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE

The Corporation covenants that if:

       (a)    default is made in the payment of any instalment of interest on
              any Note and any related Coupon when such interest becomes due and
              payable and such default continues for a period of 30 days or

       (b)    default is made in the payment of the principal of (or premium, if
              any, on) any Note at the Maturity thereof,

<PAGE>

                                     - 26 -


then the Corporation will, upon demand of the Trustee, pay to the Trustee for
the benefit of the Holders of such Notes and Coupons the whole amount then due
and payable on such Notes and Coupons for principal (and premium, if any) and
interest, and interest on any overdue principal (and premium, if any) and on any
overdue interest, at the rate or rates prescribed therefor in such Notes, and,
in addition thereto, such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Corporation fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name as trustee of an express trust, may institute ajudicial
proceeding for the collection of the sums so due and unpaid, may prosecute such
proceeding to judgment or final decree and may enforce the same against the
Corporation or any other obligor upon such Notes and collect the moneys adjudged
or decreed to be payable in the manner provided by law out of the property of
the Corporation or any other obligor upon such Notes, wherever situated.

If an Event of Default with respect to Notes of any series (or of all series, as
the case may be) occurs and is continuing, the Trustee may in its discretion
proceed to protect and enforce its rights and the rights of the Holders of Notes
of such series (or of all series, as the case may be) by such appropriate
judicial proceedings as the Trustee shall deem most effectual to protect and
enforce any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy.

6.5    TRUSTEE MAY FILE PROOFS OF CLAIM

In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustments, composition or other
judicial proceeding relative to the Corporation or any other obligor upon the
Notes or the property of the Corporation or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Notes shall
then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the
Corporation for the payment of overdue principal, premium, if any or interest)
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

       (a)    to file and prove a claim for the whole amount of principal (and
              premium, if any) and interest owing and unpaid in respect of the
              Notes and to file such other papers or documents as may be
              necessary or advisable in order to have the claims of the Trustee
              (including any claim for the reasonable compensation, expenses,
              disbursements and advances of the Trustee, its agents and counsel
              and any sales, value added or goods and services tax thereon) and
              of the Holders allowed in such judicial proceedings, and

       (b)    to collect and receive any moneys or other property payable or
              deliverable on any such claim and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under section 5.4.

Nothing herein contained shall be deemed to authorize the Trustee to authorize
or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

6.6    TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF NOTES

All rights of action and claims under this Indenture or the Notes or Coupons may
be prosecuted and enforced by the Trustee without the possession of any of the
Notes or Coupons or the production thereof in any proceedings relating thereto,
and any such proceeding instituted by the Trustee shall be brought in its own
name as trustee of an express-trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel and any sales,
value-added or goods and services tax thereon, be for the rateable benefit of
the Holders of the Notes and Coupons in respect of which such judgement has been
recovered.

6.7    APPLICATION OF MONEY COLLECTED

Any money collected by the Trustee pursuant to this Article shall be applied in
the following order, at the date or dates fixed by the Trustee and, in case of
the distribution of such money on account of principal (or premium, if any, on)
or interest, upon presentation of the Notes or Coupons, or both, as the case may
be, and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid:

       First:        To the payment of all amounts due the Trustee under section
                     5.4;

       Second:       To the payment of the amounts then due and unpaid for
                     principal of (and premium, if any) and interest on the

                     which such money has been collected, rateably, without
                     preference or priority of any kind, according to the
                     amounts due and payable on such Notes and Coupons for
                     principal (and premium, if any) and interest, respectively;
                     and

       Third:        The balance, if any, to the Person or Persons entitled
                     thereto.

6.8    LIMITATION ON SUITS

No Holder of any Note of any series or any related Coupons shall have any right
to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless

       (a)    such Holder has previously given written notice to the Trustee of
              a continuing Event of Default with respect to the Notes of that
              series;

       (b)    the Holders of not less than 25% in principal amount of the
              outstanding Notes of that series in the case of any Event of
              Default described in clause (a), (b) or (j) of section 6.1, or, in
              the case of any Event of Default described in clause (c), (d),

              than 25% in principal amount of all outstanding Notes, shall have
              made written request to the Trustee to institute proceedings in
              respect of such Event of Default in its own name as Trustee
              hereunder;

       (c)    such Holder or Holders have offered to the Trustee reasonable
              indemnity against the costs, expenses and liabilities to be
              incurred in compliance with such request;

       (d)    the Trustee for 60 days after its receipt of such notice, request
              and offer of indemnity has failed to institute any such
              proceeding, and

       (e)    no direction inconsistent with such written request has been
              given, by Extraordinary Resolution, to the Trustee during such 60
              day period by the Holders of the outstanding Notes of that series
              in the case of any Event of Default described in clause (a), (b)
              or (j) of section 6.1, or, in the case of any

              Event of Default described in clause (c), (d), (e), (f), (g), (h)
              or (i) of section 6.1, by the Holders of all outstanding Notes;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of Notes of the same series, in the case of any Event of Default
described in clause (a), (b) or (j) of section 6.1 or of Holders of all Notes in
the case of an Event of Default described in clause (c), (d), (e), (f), (g), (h)
or (i) of section 6.1, or to obtain or to seek to obtain priority or preference
over any other of such Holders or to enforce any right under this Indenture,
except in the manner herein provided and for the equal and rateable benefit of
all Holders of Notes of the same series, in the case of any Event of Default
described in clause (a), (b) or (j) of section 6.1, or of Holders of all Notes
in the case of any Event of Default described in clause (c), (d), (e), (f), (g),
(h) or (i) of section 6.1.

6.9    RESTORATION OF RIGHTS AND REMEDIES

If the Trustee or any Holder has instituted any proceeding to enforce any right
or remedy under this Indenture and such proceeding has been discontinued or
abandoned for any reason, or has been determined adversely to the Trustee or to
such Holder, then and in every such case, subject to any determination in such
proceeding, the Corporation, the Trustee and the Holders of Notes and Coupons
shall be restored severally and respectively to their former positions hereunder
and thereafter all rights and remedies of the Trustee and the Holders shall
continue as though no such proceeding had been instituted.

6.10   RIGHTS AND REMEDIES CUMULATIVE

No right or remedy herein conferred upon or reserved to the Trustee or to the
Holders of Notes or Coupons is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in additional to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

6.11   DELAY OR OMISSION NOT WAIVER

No delay or omission of the Trustee or of any Holder of any Notes or Coupons to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein.  Every right and remedy given by this Indenture or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

6.12   CONTROL BY HOLDERS

With respect to the Notes of any series, the Holders of the outstanding Notes of
such series shall have the right, by Extraordinary Resolution, to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred on the Trustee relating
to or arising under clause (a), (b) or (j) of section 6.1, and, with respect to
all Notes, the Holders of all outstanding Notes shall have the right to direct,
by Extraordinary Resolution, the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred on the Trustee, or exercising any trust or power conferred on
the Trustee, not relating to or arising under clause (a), (b) or (j) of section
6.1, provided that in each case:

       (a)    such direction shall not be in conflict with any rule of law or
              with this Indenture,

       (b)    the Trustee may take any other action deemed proper by the Trustee
              which is not inconsistent with such direction, and

<PAGE>

                                      -29-

       (c)    the Trustee need not take any action which might involve it in
              personal liability or be unjustly prejudicial to the Holders of
              Notes of such series not consenting.

6.13   WAIVER OF PAST DEFAULTS

Subject to section 6.3, the Holders of the outstanding Notes of any series may
on behalf of the Holders of all the Notes of such series, by Extraordinary
Resolution, waive any past default described in clause (a), (b) or (j) of
section 6.1 (or, in the case of a default described in clause (c), (d), (e),
(f), (g), (h) or (i) of section 6.1, the Holders of all outstanding Notes may,
by Extraordinary Resolution, waive any such past default), and its consequences,
except a default:

       (a)    in respect of the payment of the principal of (or premium, if any)
              or interest of any Note or any related Coupon, or

       (b)    in respect of a covenant or provision hereof which under Article
              12 cannot be modified or amended without the consent of the Holder
              of each outstanding Note of such series affected.

Upon any such waiver, any such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or Event of Default or impair any right consequent thereon.

6.14   WAIVER OF STAY OR EXTENSION

The Corporation covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Corporation (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of

7.1    CANCELLATION AND DESTRUCTION

All matured Notes and Coupons shall forthwith after payment thereof be delivered
to the Trustee and cancelled by it.  All Notes and Coupons which are cancelled
or required to be cancelled under this or any other provision of this Indenture
shall be destroyed by the Trustee and, if required by the Corporation, the
Trustee shall furnish to the Corporation a destruction certificate setting out
the designating numbers and denominations of the Notes and Coupons so destroyed.

7.2    NON-PRESENTATION OF NOTES AND COUPONS

If the Holder of any Note or Coupon shall fail to present the same for payment
on the date on which the principal thereof and/or the interest thereon or
represented thereby becomes payable either at Maturity or otherwise or shall not
accept payment on account thereof and give such receipt therefor (if any) as the
Trustee may require:

       (a)    the Corporation shall be entitled to pay to the Trustee and direct
              it to set aside; or

       (b)    in respect of moneys in the hands of the Trustee which may or
              should be applied to the payment of the Notes, the Corporation
              shall be entitled to direct the Trustee to set aside;

<PAGE>

                                      -30-

the principal moneys and/or the interest, as the case may be, in trust to be
paid to the Holder of such Note or Coupon upon due presentation and surrender
thereof in accordance with the provisions of this Indenture; and thereupon the
principal moneys and/or the interest payable on or represented by each Note and
each Coupon in respect whereof such moneys have been set aside shall be deemed
to have been paid and thereafter such Notes and Coupons shall not be considered
as outstanding hereunder and the Holders thereof shall thereafter have no right
in respect thereof except that of receiving payment of the moneys so set aside
by the Trustee (without interest thereon) upon due presentation and surrender
thereof, subject always to the provisions of section 5.6 as they relate to the
repayment of unclaimed moneys. Any moneys so set aside may, and, if remaining
unclaimed for 60 days shall, be invested by the Trustee in accordance with
section 11.8.

7.3    DEFEASANCE

The Trustee shall, at the request and at the expense of the Corporation, execute
and deliver to the Corporation such deeds or other instruments as shall be
necessary to release the Corporation, subject to section 7.4, from its covenants
contained herein except those relating to the indemnification of the Trustee and
to the maintenance of an office or agency for the Notes as contemplated by
sections 5.4 and 5.5 upon:

       (a)    proof being given to the reasonable satisfaction of the Trustee
              that the Corporation has deposited funds or made provision for
              payment of the expenses of the Trustee, for payment of all
              principal and interest and other amounts due or to become due on
              the Notes (including amounts due or to become due with respect to
              any series of Notes as a result of a provision contemplated by
              section 2.2) and for the payment of Taxes arising with respect to
              such deposited funds or other provision for payment (collectively,
              the "Payments") pursuant to the terms of an irrevocable trust
              agreement in form and substance satisfactory to the Trustee; and

       (b)    delivery by the Corporation to the Trustee of an opinion of
              Counsel, which opinion shall be satisfactory to the Trustee in its
              sole discretion, that the Noteholders will not be subject to any
              Taxes as a result of the Corporation's exercise of this defeasance
              option and that they will be subject to Taxes, including those in
              respect of income (including taxable capital gains), in the same
              amount, in the same manner and at the same time or times as would
              have been the case if such option had not been exercised.

The Corporation shall be deemed to have made such due provision for payment if,
and only if, it has deposited or caused to be deposited with the Trustee under
the terms of the irrevocable trust agreement, and solely for the benefit of the
Noteholders for the purpose stated therein, cash or securities issued or
guaranteed by the Government of Canada which will be sufficient, in the opinion
of an independent chartered accountant or investment dealer acceptable to the
Trustee, to provide for the Payments.

The Trustee shall hold in trust, all monies or securities deposited with it
pursuant to this section 7.3, and shall apply the deposited monies and the money
from such securities in accordance with this Indenture to the payment of
principal of, interest and premium, if any, on the Notes.

7.4    TRUSTEE UNABLE TO APPLY MONEY OR NOTES

If the Trustee is unable to apply any money or securities in accordance with
section 7.3 by reason of any legal proceeding or by reason of any order or
judgment of any Court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Corporation's obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit of
money or securities had occurred pursuant to section 7.3 until such time as the
Trustee is permitted to apply all such money or securities in accordance with
section 7.3; provided that if the Corporation has made any principal or interest
payments or paid any premium, if any, on the Notes because of the reinstatement
of its obligations, the Corporation shall be subrogated to the rights of the
Noteholders of such Notes to receive such payment from the money or securities
held by the Trustee.  Notwithstanding the foregoing, upon proof

<PAGE>

                                      -31-

being given to the reasonable satisfaction of the Trustee that all the Notes
of a particular series and the premium, if any, thereon, and interest
(including interest on amounts in default) thereon and other moneys payable
in respect thereof have been paid or satisfied or that, all the outstanding
Notes of a particular series having matured or having been duly called for
redemption, or the Trustee having been given irrevocable instructions by the
Corporation to publish within ninety (90) days notice of redemption of all
the outstanding Notes of a particular series, such payment and/or redemption
has been duly and effectually provided for by payment to the Trustee or
otherwise, and upon payment of all costs, charges and expenses properly
incurred by the Trustee in relation to the supplemental indenture providing
for the issue of such series of Notes and all interest thereon, or upon
provision satisfactory to the Trustee being made therefor, the Trustee shall
at the request and at the expense of the Corporation, execute and deliver to
the Corporation such deeds or other instruments as shall be requisite to
evidence the satisfaction and discharge of the supplemental indenture
providing for the issue of such series of Notes and to release the
Corporation from the covenants therein contained.

7.5    DISCHARGE

Upon proof being given to the reasonable satisfaction of the Trustee that all
the Notes and interest (including interest on amounts in default) thereon have
been paid or satisfied or that, all the outstanding Notes having matured, such
payment has been duly provided for by payment to the Trustee or otherwise, and
upon payment of all costs, charges and expenses properly incurred by the Trustee
in relation to this Indenture and all interest thereon and the remuneration of
the Trustee, or upon provision satisfactory to the Trustee being made therefor,
the Trustee shall, at the request and at the expense of the Corporation, execute
and deliver to the Corporation such deeds or other instruments as shall be
necessary to evidence the satisfaction and discharge of this Indenture and to
release the Corporation from its covenants contained herein except those
relating to the indemnification of the Trustee.

                               SUCCESSOR CORPORATIONS

8.1    CERTAIN REQUIREMENTS IN RESPECT OF MERGER ETC.

The Corporation shall not enter into any transaction, whether by way of
amalgamation (except a vertical short-form amalgamation with one or more of its
wholly-owned Subsidiaries pursuant to the BUSINESS CORPORATIONS ACT (Yukon)),
merger, reconstruction, reorganization, consolidation, transfer, sale, lease or
otherwise, whereby all or substantially all of its undertaking, property and
assets would become the property of any other Person or, in the case of any such
amalgamation, of the continuing corporation resulting therefrom, but may do so
if:

       (a)    such other Person or continuing corporation is a corporation (the
              "Successor Corporation.") incorporated under the laws of Canada or
              any province thereof;

       (b)    the Successor Corporation shall execute, prior to or
              contemporaneously with the completion of such transaction, such
              indenture supplemental hereto and other instruments (if any) as
              are satisfactory to the Trustee and in the opinion of Counsel are
              necessary or advisable to evidence the assumption by the Successor
              Corporation of the liability for the due and punctual payment of
              all the Notes and the interest thereon and all other moneys
              payable thereunder and the covenant of such Successor Corporation
              to pay the same and its agreement to observe and perform all the
              covenants and obligations of the Corporation under this Indenture;

       (c)    such transaction shall, to the satisfaction of the Trustee and in
              the opinion of Counsel, be upon such terms as substantially to
              preserve and not to impair any of the rights and powers of the
              Trustee or of the Noteholders hereunder and upon such terms as are
              not in any way prejudicial to the interests of the Noteholders;
              and

<PAGE>

                                      -32-

       (d)    no condition or event shall exist in respect of the Corporation or
              the Successor Corporation, either at the time of such transaction
              or immediately thereafter after giving full effect thereto, which
              constitutes or would, after the giving of notice or the lapse of
              time or both, constitute an Event of Default hereunder.

8.2    VESTING OF POWERS IN SUCCESSOR

Whenever the conditions of section 8.1 have been duly observed and performed,
the Trustee shall execute and deliver the supplemental indenture provided for in
Article 12 and thereupon:

       (a)    the Successor Corporation shall possess and from time to time may
              exercise each and every right and power of the Corporation under
              this Indenture in the name of the Corporation or otherwise, and
              any act or proceeding by any provision of this Indenture required
              to be done or performed by any Directors or officers of the
              Corporation may be done and performed with like force and effect
              by the like directors or officers of such Successor Corporation;
              and

       (b)    the Corporation shall be released and discharged from liability
              under this Indenture and the Trustee may execute any documents
              which it may be advised are necessary or advisable for effecting
              or evidencing such release and discharge.


                                     ARTICLE 9
                              MEETINGS OF NOTEHOLDERS

9.1    RIGHT TO CONVENE MEETINGS

The Trustee may at any time and from time to time and shall, (i) on receipt of a
Written Request of the Corporation or a written request signed by the Holders of
not less than 25% in principal amount of the Notes of any series then
outstanding and upon being indemnified to its reasonable satisfaction by the
Corporation or by the Holders of the Notes of such series signing such request
against the costs which may be incurred in connection with the calling and
holding of such meeting, convene a meeting of the Holders of the Notes of such
series and, (ii) on receipt of a Written Request of the Corporation or a
Noteholders' Request and upon being indemnified to its reasonable satisfaction
by the Corporation or by the Noteholders against the costs which may be incurred
in connection with the calling and holding of such meeting, convene a meeting of
the Noteholders. If the Trustee fails within 30 days after receipt of such
written request and such indemnity to give notice convening a meeting, the
Corporation, such Noteholders or the Holders of the Notes of such series, as the
case may be, may convene such meeting.  Every such meeting shall be held in the
city of Calgary or at such other place as may be approved or determined by the
Trustee.

9.2    NOTICE OF MEETINGS

At least 21 days' notice of any meeting of Noteholders or the Holders of the
Notes of a series shall be given to the Noteholders or the Holders of the Notes
of such series, as the case may be, in accordance with section 10.2 and a copy
thereof shall be sent by mail to the Trustee unless the meeting has been called
by it and to the Corporation unless the meeting has been called by it. Such
notice shall state the time when and the place where the meeting is to be held
and shall state briefly the general nature of the business to be transacted
thereat, but it shall not be necessary for any such notice to set out the terms
of any resolution to be proposed at the meeting or any of the provisions of this
Article.

9.3    CHAIRMAN

An individual, who need not be a Noteholder or a Holder of the Notes of such
series, as the case may be, nominated in writing by the Trustee shall be
chairman of the meeting and if no individual is so nominated or the individual
so nominated is unable or unwilling to act or if the individual so nominated is
not present within 15 minutes from the

<PAGE>

                                      -33-

time fixed for the holding of the meeting, the Noteholders or the Holders of
the Notes of such series, as the case may be, present in person or by proxy
shall choose an individual present to be chairman.

9.4    QUORUM

At any meeting of the Noteholders or the Holders of any series of Notes, as the
case may be, other than a meeting convened for the purpose of considering a
resolution proposed to be passed as an Extraordinary Resolution, as to which the
provisions of section 9.11 shall be applicable, a quorum shall consist of
Holders present in person or by proxy and representing at least 25% in principal
amount of the outstanding Notes or Notes of such series, as the case may be. If
a quorum of the Noteholders or the Holders of Notes of such series, as the case
may be, shall not be present within 30 minutes from the time fixed for holding
any such meeting, the meeting, if convened by the Noteholders or the Holders of
Notes of such series or pursuant to a Noteholder's Request or the request of the
Holders of the Notes of a series, shall be dissolved; but in any other case the
meeting shall be adjourned to the same day in the next week (unless such day is
not a Business Day, in which case it shall be adjourned to the next following
Business Day) at the same time and place. At the adjourned meeting the
Noteholders or the Holders of Notes of such series, as the case may be, present
in person or by proxy shall form a quorum and may transact the business for
which the meeting was originally convened notwithstanding that they may not
represent 25% of the principal amount of the outstanding Notes or Notes of such
series.

9.5    POWER TO ADJOURN

The chairman of any meeting at which a quorum of the Noteholders or the Holders
of Notes of a series, as the case may be, is present may, with the consent of
the Holders of a majority in principal amount of the Notes or the Notes of such
series, as the case may be, represented thereat, adjourn any such meeting and no
notice of such adjournment need be given except such notice, if any, as the
meeting may prescribe.

9.6    SHOW OF HANDS

Every question submitted to a meeting shall be decided in the first place by a
majority of the votes given on a show of hands except that votes on
Extraordinary Resolutions shall be given in the manner hereinafter provided. At
such meeting, unless a poll is duly demanded as herein provided, a declaration
by the chairman that a resolution has been carried or carried unanimously or by
a particular majority or lost or not carried by a particular majority shall be
conclusive evidence of the fact.

9.7    POLL

On every Extraordinary Resolution, and on any other question submitted to a
meeting, when demanded by the chairman or by a Holder and/or proxies for Holders
holding at least 5% of the principal amount of the Notes or the Notes of a
series, as the case may be, represented thereat, a poll shall be taken in such
manner and either at once or after an adjournment as the chairman shall direct.
Questions other than Extraordinary Resolutions shall, if a poll is taken, be
decided by the votes of the Holders of a majority in principal amount of the
Notes or the Notes of such series, as the case may be, represented at the
meeting and voted on the poll.

9.8    VOTING

On a show of hands every Person who is present and entitled to vote, whether as
a Holder or as proxy, shall have one vote. On a poll each Holder present in
person or represented by a duly appointed proxy at the meeting of Noteholders or
the Holders of the Notes of a series shall be entitled to one vote in respect of
each $1,000 principal amount of Notes or Notes of such series, as the case may
be, of which he shall then be the Holder.  A proxy need not be a Holder of Notes
of any series.  In the case of joint registered Holders of a Note, any one of
them present in person or by proxy at the meeting may vote in the absence of the
other or others; but in case more than one of them are present in person or by
proxy, they shall vote together in respect of the Notes of which they are joint
registered Holders.

to time make and from time to time vary such regulations as it shall from time
to time think fit providing for:

       (a)    voting by proxy and the form of the instrument appointing a proxy
              (which shall be in writing) and the manner in which the same shall
              be executed and for the production of the authority of any Person
              signing on behalf of a Holder;

       (b)    the issue of voting certificates:

              (i)    by any bank, trust company or other depositary approved by
                     the Trustee certifying that specified Bearer Notes have
                     been deposited with it by a named Person and will remain on
                     deposit until after the meeting of Noteholders or Holders
                     of Notes of a series, as the case may be, specified
                     therein;

              (ii)   by any bank, trust company, insurance company, governmental
                     department or agency approved by the Trustee certifying
                     that it is the Holder of specified Bearer Notes and will
                     continue to hold the same until after the meeting of
                     Noteholders or Holders of Notes of a series, as the case
                     may be, specified therein;

              which voting certificates shall entitle the Persons named therein
              to be present and vote at any such meeting and at any adjournment
              thereof or to appoint a proxy or proxies to represent them at such

              the same effect as though the persons so named in such voting
              certificates were the actual bearers of the Bearer Notes specified
              therein;

       (c)    the deposit of voting certificates and/or instruments appointing
              proxies at such place as the Trustee, the Corporation or the
              Noteholders or the Holders of the Notes of a series, convening a
              particular meeting, as the case may be, may in the notice
              convening the meeting direct and the time, if any, before the

              place where the same is to be held and for the voting of proxies
              so deposited as though the instruments themselves were produced at
              the meeting.

Any regulations so made shall be binding and effective and the votes given in
accordance therewith shall be valid and shall be counted. Save as such
regulations may provide, the only Persons who shall be recognized at any meeting
as the Holders of any Notes, or as entitled to vote or be present at the meeting
in respect thereof, shall be persons who produce Bearer Notes or voting
certificates at the meeting and Holders of Registered Notes and persons whom
Holders of Registered Notes or voting certificates have duly appointed as their
proxies.

9.10   CORPORATION AND TRUSTEE MAY BE REPRESENTED

The Corporation and the Trustee, by their respective officers and directors, and
the legal advisers of the Corporation and the Trustee may attend any meeting of
the Noteholders or the Holders of Notes of any series, as the case may be, but

              then the meeting, if convened by the Noteholders or the Holders of
              Notes of such series or pursuant to a Noteholder's Request or a
              written request signed by the Holders of not less than 25% in

              by the terms of this Indenture, the Trustee shall exercise that
              degree of care, diligence and skill that a reasonably prudent

       (b)    Subject only to subsection 11.3(a), the obligation of the Trustee
              to commence or continue any act, action or proceeding for the

              Noteholders at whose instance it is acting to deposit with the
              Trustee the Notes held by them, for which Notes the Trustee shall
              issue receipts; and

       (d)    Every provision of this Indenture that by its terms relieves the
              Trustee of liability or entitles it to rely upon any evidence

              Legislation, this section 11.3 and section 11.4.

              of compliance with any provisions hereof, and in such form, as may
              be prescribed by Indenture Legislation or as the Trustee may
              reasonably require by written notice to the Corporation;

       (b)    In the exercise of its rights, duties and obligations, the Trustee
              may, if it is acting in good faith, rely as to the truth of the
              statements and the accuracy of the opinions expressed therein,
              upon statutory declarations, opinions, reports, certificates or
              other evidence referred to in subsection 11.4(a) provided that the

       (c)    The Trustee may employ or retain such counsel, auditors,
              accountants, appraisers or other experts or advisers, whose
              qualifications give authority to any opinion or report made by
              them, as it may reasonably require for the purpose of discharging

       (b)    nothing herein contained shall impose any obligation on the
              Trustee to see to or to require evidence of the registration or

other proceedings by whomsoever made, prosecuted or brought and from all loss,

              principal amount of Convertible Debentures Series 2 which the
              Holder thereof wishes to acquire (being not more than the
              principal amount which such Holder is entitled to acquire pursuant
              to the certificate(s) surrendered). If any of the Convertible
              Debentures Series 2 subscribed for are to be issued to a person or
              persons other than the Holder of the Special Notes Series A, such
              Holder shall pay to the Corporation or the Trustee on behalf of
              the Corporation, all applicable transfer or similar taxes and the
              Corporation shall not be required to issue or deliver certificates
              evidencing Convertible Debentures Series 2 unless or until such
              Holder shall have paid to the Corporation, or the Trustee on
              behalf of the Corporation, the amount of such tax or shall have
              established to the satisfaction of the Corporation that such tax
              has been paid or that no tax is due.

       (d)    Upon the conversion of Special Notes Series A pursuant to this
              section 9, and subject to subsections 9(e) and (f), the
              Convertible Debentures Series 2 subscribed for or, in the case of
              a conversion pursuant to subsection 9(i), all of the Convertible
              Debentures Series 2 issuable pursuant to the Special Notes Series
              A converted, shall be deemed to have been issued and after the
              date the certificate(s) representing Special Notes Series A are
              surrendered for exercise or the Expiry Date, as applicable, the
              certificate or certificates representing the Special Notes Series
              A shall be deemed to represent only the right to receive a
              certificate or certificates representing the Convertible
              Debentures Series 2 into which such Special Notes Series A are
              converted and the Corporation shall have no obligation to make any
              payment upon surrender of the certificate or certificates
              representing the Special Notes Series A.

       (e)    The Holder of any Special Notes Series A may exercise such
              Holder's right to acquire a principal amount of Convertible
              Debentures Series 2 less than the aggregate principal amount which
              the Holder is entitled to acquire pursuant to the surrendered
              certificate or certificates representing Special Notes Series A.
              In the event of any conversion of a principal amount of Special
              Notes Series A less than the principal amount which the Holder is
              entitled to convert, the Holder of the Special Notes Series A upon
              such conversion shall, in addition, be entitled to receive,
              without charge therefor, a new certificate or certificates in
              respect of the balance of the principal amount of the Special
              Notes Series A represented by the surrendered certificate or
              certificates and not then converted.

       (f)    Notwithstanding anything herein contained, the Corporation shall
              not be required, upon the conversion of any Special Notes Series
              A, to issue Convertible Debentures Series 2 in a principal amount
              which is not an integral multiple of US.$1,000 or to distribute
              certificates which evidence Convertible Debentures Series 2 in a
              principal amount which is not an integral multiple of US.$1,000.

       (g)    Subject to subsection 9(i), immediately after the Expiry Time, all
              rights under any Special Notes Series A not exercised in
              accordance with the terms and conditions of this Indenture shall
              cease and terminate and such Special Note Series A shall be void
              and of no further force or effect.

                                      A-3

       (h)    (i)    The Trustee shall promptly account to the Corporation with
                     respect to Special Notes Series A converted. Any securities
                     or other instruments, from time to time received by the
                     Trustee shall be received in trust for, and shall be
                     segregated and kept apart by the Trustee in trust for, the
                     Corporation.

              (ii)   The Trustee shall record the particulars of Special Notes
                     Series A converted, which particulars shall include the
                     principal amount converted, the date of conversion and the
                     serial numbers of all certificates surrendered or issued.
                     The Trustee shall provide such particulars in writing to
                     the Corporation within five Business Days of any request by
                     the Corporation therefor.

       (i)    At the Expiry Time, the rights of all Holders of Special Notes
              Series A (other than Special Notes Series A in respect of which
              the Holder thereof duly exercises its Retraction Right (as
              hereinafter defined) or its right to acquire Convertible
              Debentures Series 2 pursuant to subsection 9(a)) to acquire
              Convertible Debentures Series 2 shall be exercised by the Trustee
              on behalf of such Holders without any further action on the part
              of such Holders or the Corporation and the Convertible Debentures
              Series 2 issuable thereby shall be deemed to be issued to such
              Noteholders at such time. The Corporation shall cause to be
              delivered to the principal office of the Trustee in the city of
              Calgary (the "Exercise Office") where the certificate or
              certificates representing such Special Notes Series A is or are
              surrendered, to the Person or Persons specified in the exercise
              form a certificate or certificates for the appropriate principal
              amount of Convertible Debentures Series 2 upon actual receipt at
              the Exercise Office of the certificate or certificates
              representing such Special Notes Series A together with any payment
              of the nature referred to in subsection 9(c).

       (1)    Notwithstanding anything herein contained, Convertible Debentures
              Series 2 will only be issued pursuant to any conversion of Special
              Note Series A in compliance with the securities laws of any
              applicable jurisdiction, and without limiting the generality of
              the foregoing, in the event that the Special Notes Series A are
              converted pursuant to subsection 9(a) or deemed to have been
              converted pursuant to subsection 9(i) prior to the issuance of a
              receipt for a (final) prospectus regarding the distribution of
              Convertible Debentures Series 2 upon the conversion of Special
              Notes Series A (the "Prospectus") by the securities commission or
              similar securities regulatory authority (a "Securities
              Commission") in each of the provinces of British Columbia, Alberta
              and Ontario (the "Filing Jurisdictions"), the certificates
              representing the Convertible Debentures Series 2 thereby issued
              will bear such legend as may, in the opinion of Counsel to the
              Corporation, be necessary in order to avoid a violation of any
              securities laws of any province in Canada or to comply with the
              requirements of any stock exchange on which the Convertible
              Debentures Series 2 or the securities of the Corporation into
              which the Convertible Debentures Series 2 may be converted (the
              "Underlying Securities") are listed, provided that if, at any
              time, in the opinion of counsel to the Corporation, such legends
              are no longer necessary in order to avoid a violation of any such
              laws, or the Holder of any such legended certificate, at the
              Holder's expense, provides the Corporation with evidence
              satisfactory in form and substance to the Corporation (which may
              include an opinion of counsel satisfactory to the Corporation) to
              the effect that such holder is entitled to sell or otherwise
              transfer such Convertible Debentures Series 2 in a transaction in
              which such legends are not required, such legended certificate may
              thereafter be surrendered to the Corporation in exchange for a
              certificate which does not bear such legend.

       (k)    The Corporation hereby appoints the Trustee, as trustee, to
              receive, hold and deal with the Escrowed Subscription Funds in
              accordance with the terms of this Indenture and the Trustee hereby
              accepts such appointment and agrees to be bound by the terms of
              this Indenture in respect thereof. On the issuance of any Special
              Notes Series A, 40% of the aggregate principal amount of Special
              Notes Series A issued (the "Escrowed Subscription Funds") shall be
              deposited by the Agent with the Trustee. The Trustee shall not
              release any Escrowed Subscription Funds, except as provided in
              this

                                      A-4

              Section 9. Subject to subsections 9(1), (m), (n) and (o), the
              Trustee shall not deliver any of the Escrowed Subscription Funds,
              or any interest accrued thereon, unless the Trustee receives:

              (i)    a notice in writing signed by the Corporation and the Agent
                     (the "Joint Notice") confirming that a receipt for a
                     Prospectus has been issued by the Securities Commissions in
                     each of the Filing Jurisdictions on or prior to 5:00 p.m.
                     (Toronto time) on that date 120 days after the date of the
                     Indenture (the "Qualification Deadline"); or

              (ii)   an opinion of counsel (addressed to the Trustee and the
                     Agent, in form satisfactory to the Agent, acting
                     reasonably) that a receipt for a Prospectus has been issued
                     by the Securities Commissions in each of the Filing
                     Jurisdictions on or prior to 5:00 p.m. (Toronto time) on
                     the Qualification Deadline;

              in which case the Trustee shall immediately deliver all Escrowed
              Subscription Funds, together with all interest accrued thereon, to
              or to the order of the Corporation.

       (l)    If a receipt for a Prospectus has not been obtained on or prior to
              5:00 p.m. (Toronto time) on the Qualification Deadline:

              (i)    from the Securities Commission in a province which is a
                     Filing Jurisdiction, each Noteholder in such province
                     holding Special Notes Series A; or

              (ii)   from the Securities Commission in each of the provinces of
                     British Columbia and Ontario, each Noteholder holding
                     Special Notes Series A wherever situate;

              shall have the right to elect during the period commencing at the
              Qualification Deadline and expiring at 5:00 p.m. (Toronto time) on
              the date which is five Business Days following the Qualification
              Deadline (the "Election Deadline") to:

              (i)    receive upon conversion an additional 10% of the Underlying
                     Securities (the "Additional Underlying Securities") to be
                     issued on conversion of the Convertible Debentures Series 2
                     (the "Penalty"),

              OR

              (ii)   require the Corporation to repurchase 40% of the principal
                     amount of the Special Notes Series A held by the Holder at
                     the Retraction Price as hereinafter defined (the
                     "Retraction Right").

              If a Holder of Special Notes Series A fails to make an election
              prior to the Election Deadline, such Holder shall be deemed to
              have elected to receive the Penalty. If a Holder of Special Notes
              Series A elects to receive the Penalty or is deemed to have
              elected to receive the Penalty, the certificates representing the
              Convertible Debentures Series 2 issuable upon conversion of the
              Special Notes Series A shall have endorsed thereon a statement to
              the effect that upon conversion thereof the Holder shall receive
              the Additional Underlying Securities.

              The retraction price of the Special Notes Series A (the
              "Retraction Price") shall be the principal amount thereof together
              with interest equal to the product of the amount of all of the
              interest earned by the Trustee upon the Escrowed Subscription
              Funds from April 8, 1998 (the "Effective Date") to the date
              immediately preceding the date of payment (less any interest paid
              out by the Trustee pursuant to this Indenture prior to the date of
              payment) multiplied by a fraction of which the numerator is the
              principal amount of Special Notes Series A properly tendered to
              the Trustee by

<PAGE>

                                      A-5

              such Noteholder pursuant to the Retraction Right and the
              denominator is 40% of the principal amount of Special Notes
              Series A outstanding on the date of payment. Payment of the
              Retraction Price from the Escrowed Subscription Funds shall be
              made by cheque payable at par in the city of Calgary, together
              with delivery of a certificate or certificates for that
              principal amount of Convertible Debentures Series 2 equal to
              60% of the principal amount Special Notes Series A held by the
              Holder, against delivery by Noteholders to the Trustee of
              certificates representing the Special Notes Series A held by
              the Holder and such certificates shall be immediately cancelled
              and shall be void and of no further value or effect.

       (m)    If, following the payment to Holders of Special Notes Series A in
              satisfaction of the Retraction Right, there remain excess Escrowed
              Subscription Funds or interest accrued thereon, the Trustee shall
              as soon as practicable after the Expiry Date deliver to the
              Corporation all of such excess Escrowed Subscription Funds
              together with all interest accrued thereon.

       (n)    If any Holder of Special Notes Series A, at any time prior to the
              Expiry Time, elects or is deemed to elect to exercise the
              entitlement to acquire Convertible Debentures Series 2 pursuant to
              Special Note(s) Series A held by it, the Trustee shall pay to the
              Corporation from the Escrowed Subscription Funds the Retraction
              Price for each Special Note Series A converted.

       (o)    All Escrowed Subscription Funds shall be held at or administered
              through the principal office of the Trustee in the city of
              Calgary. The Trustee shall not be entitled to deal with the
              Escrowed Subscription Funds except in accordance with the terms of
              this Indenture.  In the event that the Trustee determines the
              necessity for the approval by the Holders of any matter in
              connection with this section 9, an Extraordinary Resolution of the
              Holders of Special Notes Series A shall provide sufficient
              authority upon which the Trustee may act and the Trustee shall not
              be responsible for any loss occasioned by so doing.

10.    REDEMPTION. The Special Notes Series A shall be redeemable, in whole or
       in part, at the option of the Corporation at any time after March 31,
       2002 and prior to maturity at the principal amount thereof to be
       redeemed, together with accrued and unpaid interest.

11.    CERTIFICATES. The Special Notes Series A and the certificate of the
       Trustee to be endorsed on the Special Notes Series A shall respectively
       be substantially in the form set out in Exhibit 1 hereto with such
       appropriate insertions, omissions, substitutions and variations as may be
       approved or permitted under the terms of this Indenture and/or as the
       Trustee may approve.

12.    LEGENDS. All certificates representing Special Notes Series A (and all
       certificates issued in exchange therefor or in substitution thereof)
       shall bear the following legend:

number of calendar days in such year and the number of days elapsed.

4.     INTEREST ACCRUED

The Special Notes Series A shall cease to bear interest (i) from their date of

Series A.

A thereafter shall have only the rights of a creditor of the Issuer as described
in the Indenture or such rights as may be otherwise prescribed by applicable
law.

8.     ROUNDING AMOUNTS

When making payments to holders of Special Notes Series A, fractions of US $0.01

9.     CONVERSION

Each Special Note Series A entitles the holder thereof to acquire the same

Debentures") of the Issuer, at no additional cost, at any time on or before 5:00
p.m. (Toronto time) (the "Expiry Time") on the earlier of (i) the fifth business
day after the date of issuance of a receipt from the securities commission or
similar securities regulatory authority ("Securities Commission") in the last of
the provinces of Alberta, British Columbia and Ontario (the "Qualifying
Jurisdictions") to issue such receipt for a final prospectus qualifying the
issue of Convertible Debentures to be issued upon the exercise of the Special
Notes (the "Prospectus"); and (ii) the date that is 18 months after the date of

prior to the Expiry Time shall be exercised by the trustee of the Special Notes
and the Convertible Debentures issued to the Noteholders immediately prior to
the Expiry Time without any further action on the part of the holder.

If a receipt for a Prospectus has not been obtained from the Securities
Commission in each of the Qualifying Jurisdictions on or before 5:00 p.m.
(Toronto time) on the date 120 days following the Closing Date (the
"Qualification Deadline"), then each holder of Special Notes Series A in a
Qualifying Jurisdiction in which such receipt has not been so obtained (or each
holder of Special Notes Series A wherever resident if such receipt has not been
so obtained in British Columbia and Ontario) will be entitled to receive, upon
exercise of such holder's conversion rights under the Convertible Debentures,
without payment of additional consideration, 110% of the number of Common Shares
that the principal amount thereof was previously convertible into, subject to
adjustment in certain circumstances, or, at the option of the holder of Special
Notes Series A exercisable on or before 5:00 p.m. (Toronto time) on the dates
business days following the Qualification Deadline, to retract up to 40% of the
principal amount of Special Notes Series A held thereby at the principal amount
thereof plus a pro-rata share of interest earned on 40% of the subscription
proceeds of the issue of the Special Notes Series A to the day prior to the date
of retraction.

The holder of a Special Note Series A desiring to convert such Special Note
Series A in whole or in part into Convertible Debentures shall surrender such
Special Note Series A to the specified office of the Trustee, together with the
Conversion Form on the back of such Special Note Series A or any other written
notice in a form satisfactory to the Trustee, in either case duly executed by
the holder or his executors or administrators or other legal representatives or
his or their attorney duly appointed by an instrument in writing in form and
executed in a manner satisfactory to the Trustee, exercising his right to
convert such Special Note Series A in accordance with the Indenture.

Any part, being US.$1,000 or an integral multiple thereof, of a Special Note
Series A of a denomination in excess of US. $1,000 may be converted.

10.    REDEMPTION

The Special Notes Series A are redeemable, in whole or in part, at the option of
the Issuer at any time after March 31, 2002 and prior to maturity at the
principal amount thereof to be redeemed, together with accrued and unpaid
interest.

11.    MEETINGS OF NOTEHOLDERS AND MODIFICATION

The Indenture provides that modifications and alterations thereto and to the
Special Notes issued thereunder may be made if authorized by an extraordinary
resolution. Such a resolution must be passed by the affirmative vote of the
holders of not less than 66 2/3% of the principal amount of the Notes (or in the
case of a serial meeting, where the rights of the holders of Notes of one or
more series are affected differently than the rights of the holders of any other
series, of the principal amount of the Notes of the series so affected) issued
under the Indenture represented at a meeting at which holders of more than 25%
of the principal amount of the Notes (or Notes of a particular series, in the
case of a serial meeting) then outstanding are present in person or by proxy;
provided, however, that if a meeting or serial meeting is adjourned because not
more than 25% of the principal amount of such Notes is present in person or by
proxy then at the adjourned meeting an extraordinary resolution may be passed by
the affirmative vote of the holders of not less than 662/3% of the principal
amount of the Notes represented at the meeting or serial meeting, as the case
may be. The term extraordinary resolution shall also include an instrument
signed by the holders of not less than 66 2/3% of the outstanding Notes or the
Notes of a particular series, as the case may be. An extraordinary resolution
passed at any meeting of the Noteholders will be binding on all Noteholders,
whether or not they are present at the meeting.

The Indenture also permits the Issuer and the Trustee, without the consent of
holders of Special Notes, to enter into indentures supplemental to the Indenture
for certain purposes, including without limitation (i) making provisions not
inconsistent with the Indenture as may be necessary of desirable with respect to
matters or questions arising under the Indenture which do not affect the
substance thereof and which in the opinion of the Trustee, it may be expedient
to make, provided that the Trustee shall be of the opinion that such provisions
and modifications will not be prejudicial to the interests of the Noteholders,
(ii) providing for the issue, as permitted by the Indenture, of Notes of any one
or more series, (iii) making any modification of any of the provisions of this
Indenture or the Special Notes which is of a formal, minor or technical nature,
(iv) making any additions to, deletions from or alteration of the provisions of
this Indenture which, in the op in ion of the Trustee, are not materially
prejudicial to the interests of the Noteholders and which are necessary or
advisable in order to incorporate, reflect or comply with legislation applicable
to indentures, (v) correcting or rectifying any ambiguities, defective
provisions, errors or omissions in the Indenture, provided that, in the opinion
of the Trustee, the rights of the Trustee and the Noteholders are in no way
prejudiced thereby and (vi) any other purpose not inconsistent with the terms of
this Indenture provided that, in the opinion of the Trustee, the rights of the
Trustee and of the Noteholders are in no way prejudiced thereby.

12.    EVENTS OF DEFAULT

       If an Event of Default described in clause (a) or (b) below with respect
       to Notes of any series at the time outstanding occurs and is continuing,
       then in every such case the Trustee or the Holders of not less than 25%
       in principal amount of the outstanding Notes of that series may declare
       the principal amount of all the Notes of that series to be due and
       payable immediately, by a notice in writing to the Issuer (and to the
       Trustee if given by Holders), and upon any such declaration such
       principal amount (or specified portion thereof) shall become immediately
       due and payable. If an Event of Default described in clause (c), (d),
       (e), (f), (g), (h) or (i) below occurs and is continuing, then in every
       such case the Trustee or the Holders of not less than 25% in principal
       amount of all the Notes then outstanding may declare the principal amount
       of all the outstanding Notes to be due and payable immediately, by a

              generally as they become due; or

       (f)    if (i) any other Debt of the Issuer or any Material Subsidiary

              or any such guarantee or indemnity as aforesaid shall be due and
              payable (following any applicable grace period), PROVIDED that in
              each such case the Debt exceeds in the aggregate US$1,500,000 and

<PAGE>

                                      A-16


              event continues unremedied for a period of 30 calendar days (or
              such longer period as the Trustee may in its sole discretion
              consent to in writing upon receipt of written notice from the
              Issuer); or

       (g)    if there is any final judgment or judgments for the payment of
              money exceeding in the aggregate US$1,500,000 outstanding against
              the Issuer or any Material Subsidiary which has been outstanding

              Issuer or such Material Subsidiary, as the case may be, may
              contest in good faith generally) or shall be declared or
              adjudicated by a competent court to be insolvent or bankrupt,
              shall consent to an entry of an order of relief against it in an
              involuntary bankruptcy case, shall enter into any assignment or
              other similar arrangement for the benefit of its creditors or
              shall consent to the appointment of a custodian (including,
              without limitation, a receiver, liquidator or trustee); or

       (i)    if a warranty, representation, or other statement made by or on
              behalf of the Issuer contained in the Indenture, the Notes or any
              certificate or other agreement furnished in compliance with such
              documents is false in any material respect when made and (except
              where the Trustee shall have certified to the Issuer that it
              considers such falsity to be incapable of remedy, in which case no
              such notice or continuation as is hereinafter mentioned will be
              required) such falsity continues for a period of 30 calendar days
              (or such longer period as the Trustee may in its absolute
              discretion permit) next following the service by the Trustee on
              the Issuer of notice requiring the same to be remedied.

applicable Canadian withholding tax.

more series are affected differently than the rights of the holders of any other
series, of the principal amount of the Notes of the series so affected) issued
under the Indenture represented at a meeting at which holders of more than 25%
of the principal amount of the Notes (or Notes of a particular series, in the
case of a serial meeting) then outstanding are present in person or by proxy;
provided, however, that if a meeting or serial meeting is adjourned because not
more than 25% of the principal amount of such Notes is present in person or by
proxy then at the adjourned meeting an extraordinary resolution may be passed by
the affumative vote of the holders of not less than 66 2/3% of the principal
amount of the Notes represented at the meeting or serial meeting, as the case
may be. The term extraordinary resolution shall also include an instrument

provisions, errors or omissions in the Indenture, provided that, in the opinion
of the Trustee, the rights of the Trustee and the Noteholders are in no way
prejudiced thereby and (vi) any other purpose not inconsistent with the terms of
this Indenture provided that, in the opinion of the Trustee, the rights of the
Trustee and of the Noteholders are in no way prejudiced thereby.

              into any assignment or other similar arrangement for the benefit
              of its creditors or shall consent to the appointment of a
              custodian (including, without limitation, a receiver, liquidator
              or trustee); or

       (i)    if a warranty, representation, or other statement made by or on

              documents is false in any material respect when made and (except
              where the Trustee shall have certified to the Issuer that it
              considers such falsity to be incapable of remedy, in which case no
              such notice or continuation as is hereinafter mentioned will be
              required) such falsity continues for a period of 30 calendar days
              (or such longer period as the Trustee may in its absolute
              discretion permit) next following the service by the Trustee on
              the Issuer of notice requiring the same to be remedied.

13.    TAXATION

Payments of Interest on the Special Notes Series B will be made subject to the
deduction of applicable Canadian withholding tax.

The Issuer will, subject to certain exceptions and limitations set forth below,
pay, as additional interest, such additional amounts (the "Additional Amounts")
to the holder of any Special Note Series B as may be necessary in order that
every net payment of the principal or interest on such Special Note Series B,
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 Canada (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 Canada (or any political subdivision thereof) otherwise
than by the mere holding of the Special Note Series B or the receipt of payments
made under or with respect to the Special Note Series B AND PROVIDED THAT THE
SUM OF SUCH ADDITIONAL AMOUNTS AND INTEREST OTHERWISE PAYABLE, SHALL NOT EXCEED
(AND FOR GREATER CERTAINTY THE ISSUER WILL NOT BE OBLIGATED TO PAY IN EXCESS OF)
10/9 OF THE AMOUNT OF INTEREST OTHERWISE PAYABLE.

In addition, the Issuer will indemnify and hold harmless each holder of a
Special Note Series B (subject to the exclusion and limitation set forth above)
and will, upon written request of each holder (subject to the exclusion and
limitation 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 Canada and paid by the holder as a result of payments
made under or with respect to the Special Notes Series B. Any payment made
pursuant to this paragraph shall be considered an Additional Amount.

If, at any time, the Trustee is required by law to make any deduction or
withholding from any sum payable by it hereunder (or if thereafter there is any
change in the rates at which or the manner in which such deductions or
withholdings are calculated), the Issuer shall promptly notify the Trustee and
shall deliver to the Trustee, within thirty days after it has made such payment
to the applicable authority, an original receipt (or a certified copy thereof)
issued by such authority evidencing the payment to such authority of all amounts
so required to be deducted or withheld in respect of each Special Note Series B.

If the Issuer becomes generally subject at any time to any taxing jurisdiction
other than or in addition to Canada, references in these Conditions to Canada
shall be read and construed as reference to Canada and/or to such other
jurisdiction.

Any reference in these Conditions to interest in respect of the Special Notes
Series B shall be deemed also to refer to any Additional Amounts which may be
payable under this Condition.

14.    REPLACEMENT OF SPECIAL NOTES SERIES B

If any Special Note Series B shall at any time become mutilated, defaced,
destroyed, stolen or lost, it may be replaced at the cost of the claimant at the
specified office of the Trustee upon provision of such evidence, indemnity,
security or otherwise as the Issuer determines satisfactory. Mutilated or
defaced Special Notes Series B must be surrendered before replacements will be
issued.

15.    GOVERNING LAW AND JURISDICTION

The Special Notes Series B are governed by, and shall be construed in accordance
with, the laws of the Province of Ontario and the laws of Canada applicable
thereto.

(the "Company"), in connection with the registration under the Securities Act
of 1933, as amended, on Form SB-2 file no. 333-83651 (the "Registration
Statement") of the resale by certain selling security holders of (i) 239,701
shares of the Company's Class A, Series II Convertible Preferred Stock, par
value $1.00 per share, 101,407,269 shares of the Company's common stock, par
value $.01 per share, issuable upon conversion of the Class A, Series II
Convertible Preferred Stock, and 4,583,726 shares of the Company's common
stock, par value $.01 per share (collectively the "Issued Shares") and (ii)
3,974,923 shares of the Company's common stock, par value $.01 per share,
issuable upon the exercise of outstanding warrants to purchase common stock
(the "Warrant Shares," and together with the Issued Shares, the "Shares").
The Shares are to be sold from time to time in the over-the-counter market at
prevailing prices or as otherwise described in the Registration Statement.

     In connection therewith, we have examined originals or copies, certified
or otherwise identified to our satisfaction, of the Certificate of
Incorporation of the Company, the Bylaws of the Company, the records of
corporate proceedings with respect to the offering of the Shares and such
other documents and instruments as we have deemed necessary or appropriate
for the expression of the opinions expressed herein. We have also examined
the Registration Statement, as amended, covering the resale of the Shares.

     We have assumed the authenticity and completeness of all records,
certificates and other instruments submitted to us, the conformity to
original documents of all records, certificates and other instruments
submitted to us as copies and the correctness of all statements of fact
contained in all records, certificates and other instruments we have
examined.

     Based on the foregoing, and having regard for such legal considerations
as we have deemed relevant, we are of the opinion that the Issued Shares are
duly and validly issued, fully paid and nonassessable and the Warrant Shares,
when issued in accordance with the terms of the warrant, will be duly and
validly issued, fully paid and nonassessable.

     The opinions expressed herein relate solely to, are based solely upon
and are limited exclusively to the corporate law of the State of Delaware and
the federal laws of the United States of America, to the extent applicable.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name under the caption "Legal
Matters" in the Prospectus included as a part of the Registration Statement.
