                                AUDITORS' REPORT



To the Directors of
Novalta Resources Inc.

We have audited the consolidated balance sheets of Novalta Resources Inc. as at
December 31, 1993 and 1992 and the consolidated statements of income, deficit
and cash flows for the  years then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these 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 an audit to obtain
reasonable assurance 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.

In our opinion, these consolidated financial statements present fairly, in all
material respects, the financial position of the Company as at December 31,
1993 and 1992 and the results of its operations and the changes in its
financial position for the years then ended in accordance with accounting
principles generally accepted in Canada.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of Novalta Resources
Inc. (the "Company") and its subsidiaries. Substantially all of the exploration
and production activities of the Company are conducted jointly with others, and
accordingly, these financial statements reflect only the Company's
proportionate interest in such activities.

All amounts are reported in Canadian dollars.

FIXED ASSETS

Under the successful efforts method of accounting, costs of land acquisition,
costs to drill and equip exploratory wells that find proved reserves, and costs
to drill and equip development wells are capitalized. All other exploration
costs, including costs to drill unsuccessful exploratory wells, geological and
geophysical costs, and the costs of carrying and retaining unproved properties
are expensed as incurred.  Acquisition costs of unproved properties are
amortized over the remaining term of the lease or until reserves are proved or
the property is impaired and a loss is recognized at the time of impairment.
Proved properties are carried at the lesser of cost or an ultimate recoverable
amount.

Capitalized costs of proved oil and gas properties are amortized by the
unit-of-production method based on reserve estimates prepared by an independent
consultant using end of the year prices.

Other fixed assets are being depreciated using the declining balance method at
annual rates varying from 10% to 50%, which are designed to amortize the costs
of the assets over their estimated useful lives.

Future removal and site restoration costs for petroleum and natural gas
properties are provided on the unit-of-production method.

INVESTMENTS

Investments are accounted for using the equity method of accounting.

COMPARATIVE FIGURES

Certain comparative figures have been reclassified to conform with the
financial statement presentation adopted for the current year.

The Revolving Term Credit Facility, at the Company's request, was terminated on
September 16, 1993.

At December 31, 1992, the Company had two interest rate swap agreements
outstanding which had effectively fixed the interest rates on $40,000,000 of
available borrowing at 11.01% and 11.10% for the years 1993 and 1994
respectively. The agreements were terminated during 1993.

SFAS 109 "Accounting for Income Taxes" requires the use of the liability
method under which deferred tax assets and liabilities are recognized for the
estimated future tax consequences attributable to differences between the
financial statement carrying amounts of existing assets and liabilities and
their respective tax bases. Deferred tax assets and liabilities are measured
using enacted tax rates in effect for the year in which the temporary
differences are expected to be recovered or settled. Effective January 1, 1992,
the Company adopted the provisions of FAS 109 for US basis accounting purposes.
The cumulative effect of this change in accounting principle is included in the
Company's consolidated net loss for US reporting purposes for the year ended
December 31, 1992.

On a U.S. basis, proceeds on dispositions would be reflected net of the
$4,149,000 Investment in EBOC Energy Ltd., and a corresponding amount would be
reflected as non-cash investing activities.

Deferred credits in the amount of $1,189,000 in 1993 ($1,271,000 in 1992),
which are reflected as a component of cash used in financing activities, would
be reflected as a change in working capital other than cash on a U.S. basis. As
a result of this adjustment, cash provided by operating activities would be
$19,906,000 in 1993 ($17,002,000 in 1992) and cash used in financing activities
would be $5,607,000 in 1993 ($11,893,000 in 1992).

The Company's standardized measure of future net cash flows and changes therein
as of December 31, 1993 and 1992 are provided on the present value of future
net revenues from proved gas and oil reserves estimated by independent
petroleum engineers in accordance with the guidelines
established by the Securities and Exchange Commission. These estimates were
computed by applying appropriate current prices for gas and oil to estimated
future production of proved gas and oil reserves over the economic lives of the
reserves assuming continuation of existing conditions. Year end 1993
calculations were made utilizing average prices for gas and oil, condensate and
natural gas liquids that existed at December 31, 1993 of $2.12 per Mcf and
$12.57 per barrel , respectively. Income taxes are computed by applying the
statutory federal and provincial tax rates to the net cash inflows relating to
proved gas and oil reserves less the tax bases of the properties involved and
giving effect to any tax credits and allowances relating to such properties.
The reserve volumes provided by the independent petroleum engineers are
estimates only and should not be construed as being exact quantities. These may
or may not be recovered and may increase or decrease as a result of future
operations of the Company and changes in market conditions.
