HIGHLIGHTS

SOME OF THE HIGHLIGHTS INCLUDE THE FOLLOWING ITEMS IN Q1, 2002 AS COMPARED TO
Q1, 2001:

o    INCREASED Q1 PRODUCTION BY 97% FROM 1,232 BOE/DAY TO 2,422 BOE/DAY

o    INCREASED Q1 REVENUE BY 31% FROM $4.3 MILLION TO $5.6 MILLION

o    INCREASED Q1 OPERATING CASH FLOW BY 35% FROM $1.8 MILLION TO $2.4 MILLION

o    INCREASED Q1 EARNINGS BY 422% FROM $0.6 MILLION TO $3.2 MILLION

o    DECREASED Q1 OPERATING COSTS PER BOE BY 36% FROM $12.32 TO $7.88

o    DECREASED Q1 ADMINISTRATIVE EXPENSES PER BOE BY 51% FROM $2.32 TO $1.13

o    STRENGTHENED BALANCE SHEET BY REDEEMING PREFERRED SHARES AT A SUBSTANTIAL
     DISCOUNT, RESULTING IN A GAIN OF $2.9 MILLION


OPERATIONS

Net earnings for the quarter were $3.1 million (a 416% increase over the same
period in 2001) or $0.34 on a per share basis (compared to $0.11 per share in
2001). Included in the Q1, 2002 earnings was a one-time gain of $2.9 million as
a result of the Company redeeming 83% of its Series 1 preferred shares for $2.3
million. Enterra was able to redeem over 6 million Series 1 preferred shares for
approximately $0.37 per share, a 56% discount over their stated redemption value
of $0.85 per share. Enterra saved $2.9 million by acting quickly when a unique
opportunity presented itself. The Company's balance sheet is now much stronger
as a result of this transaction.

Enterra increased its cash flow by 35% in Q1, 2002 to $2.4 million (compared to
$1.8 million in Q1, 2001 after excluding last to the settlement of hedges) or
$0.27 on a per share basis (compared to $0.33 per share in 2001, again excluding
the impact of the gain on settlement of hedges).

As mentioned in the Company's criteria and the best measure of success for
Enterra. The Company was able to actually increase operating cash flow in a
quarter where prices were, on average, 34% lower than one year ago. We feel this
is a tremendous accomplishment. We have managed to reduce our administrative
expenses by 51% and our operating costs by 36% while increasing our production
by 97%.

Drilling activity in the first quarter resulted in a significant discovery at
Gordondale where gas was found in four separate formations. The discovery well
is already on production at more than 2 mmcf/day. Enterra has identified 15 or
more additional potential drilling locations ranging from 200 meters to 2,450
meters. The area has multi-zone potential with more than 10 different producing
formations. Enterra is the operator of the well and holds interests ranging from
30% (including the discovery well) to 100% over 5,600 acres.

BALANCE SHEET CLASSIFICATION

Readers may notice that the Company's current liability, whereby the same bank
debt was a long-term liability at December 31, 2001. Nothing has changed with
the nature or the terms of our banking arrangement with our lender. The
reclassification of our bank debt from long-term liability to current liability
is the result of new accounting rules which came into effect January 1, 2002.
These rules specify that all borrowings where, among other things, the lender
has a right to demand repayment within 12 months (which is the case with our
revolving production facility) are to be classified as current liabilities.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
For the Three Months Ended March 31, 2002 and 2001
(Unaudited)


The interim consolidated financial statements have been prepared by management
in accordance with Canadian generally accepted accounting principles. The
interim consolidated financial statements have been prepared following the same
accounting policies and methods used in preparing the consolidated financial
statements for the fiscal year ended December 31, 2001, except as described
below, and should be read in conjunction with those statements. The other
disclosures below are incremental to those reflected in the annual statements.

1.   SIGNIFICANT ACCOUNTING POLICIES

     (a)  Capital assets

          As disclosed in the December 31, 2001 financial statements, the
          Company has changed its method of accounting for petroleum and natural
          gas properties from the "successful efforts" method to the "full cost"
          method. The full cost method has been adopted retroactively and prior
          financial statements have been restated. There was no impact of this
          change on the March 31, 2001 consolidated income statement.

2.   SERIES 1 PREFERRED SHARES:

          On March 26, 2002 the Company purchased 6,123,870 of its Series 1
          preferred shares for $2.3 million, resulting in a gain on redemption
          of $2,905,290. The purchase was paid for with cash of $1,750,000 and a
          note payable of $550,000. The note payable bears no interest and is
          due December 31, 2002. As at March 31, 2002 there were 1,294,466
          Series 1 preferred shares outstanding. These shares are non-voting.
          They are transferable. Holders of these shares are not entitled to
          receive any dividends until the first anniversary of the date of
          issue. These shares are redeemable at any time by the Company for
          $0.85 per share. Holders of these shares may require the Company to
          redeem all or any of these shares, at $0.85 per share, at any time
          following the first anniversary of the date of issue (August 16,
          2001). There is no market for these shares and none is expected to
          develop.

3.   WARRANTS

          On March 28, 2002 the Company agreed to issue 400,000 share purchase
          warrants to an length U.S.-based consulting firm in connection with a
          potential debt financing in the United States. The warrants are to
          have a two-year term and are subject to different pricing (100,000
          warrants at US$2.60, 100,000 at US$3.30 and 200,000 at US$4.00). The
          US$2.60 warrants are to vest upon the execution of a non-binding
          letter of intent relating to the proposed financing. The US$3.30 and
          US$4.00 warrants are to vest only on the successful closing and
          funding of the proposed financing.

4.   STOCK BASED COMPENSATION

          Effective January 1, 2002 the Company prospectively adopted the new
          recommendations of the CICA with respect to the accounting for
          stock-based compensation and other stock-based payments. In accordance
          with the new standard, the Company elected to continue its policy that
          no compensation is recorded on the grant of employee stock options and
          consideration paid on the exercise of such options is recorded as
          share capital. In addition, the new standard requires a fair value
          based method of accounting for other stock-based payments. Had
          compensation expense for the stock-based compensation plan been
          determined based on the fair value at the grant dates for awards under
          the plan after January 1, 2002, the Company's been the same as those
          reported as there were no stock options issued during the quarter.

5.   BANK INDEBTEDNESS

          Bank indebtedness represents the outstanding balance under a line of
          credit of $21,500,000 with the Alberta Treasury Branches. Drawings
          bear interest at 0.25% above the Security is provided by a first
          charge over all of the Company's demand. While the loan is due on
          demand, the Company is not subject to scheduled repayments.

          This loan was classified as a long-term liability in the December 31,
          2001 financial statements. However, effective for fiscal periods
          commencing January 1, 2002, the Company adopted the new CICA
          recommendation regarding Balance Sheet Classification of Callable Debt
          Obligations and Debt Obligations Expected to be Refinanced. All
          borrowings where the lender has a right to demand repayment within 12
          months are required to be classified as current liabilities. The
          impact of this change has been to increase current liabilities by the
          amount of any such borrowings then in place. At March 31, 2002, this
          change has increased current liabilities by $21,143,550 and reduced
          long-term debt by a corresponding amount.

          The Company is currently not subject to principal repayments and no
          payments are required in 2002.
