     This report contains certain forward-looking statements that involve risks
and uncertainties. Actual results could differ from those anticipated due to a
number of factors including the capital intensive nature of the Company's
business and its need for additional funds for operations and debt service
requirements, fluctuations in operating results, dependence upon principal
customers and on the activity of the oil and gas industry, risks associated with
international operations and regulatory, competitive and contractual risks.
 
                                     PART I
 
ITEM 1.  BUSINESS
 
OVERVIEW
 
     Venture Seismic Ltd. ("Venture" or "the Company") is a provider of seismic
data to oil and gas companies, primarily in North America. Seismic data enables
oil and gas companies to evaluate the earth's subsurface to determine the
potential of a hydrocarbon bearing structure and assist oil and gas companies in
determining the size and structure of previously identified oil and gas fields.
The seismic data is obtained by using an energy source, such as dynamite or
vibroseis units, to send acoustic energy deep into the earth's subsurface. As
these acoustic signals reflect off different subsurface structures their
reflection time can be measured by an array of small motion sensitive
transducers, called geophones, placed at specific intervals on the earth's
surface. The resulting electrical signals are then amplified, converted into
digital form and relayed to a central recording unit for storage on magnetic
tape. The data can then be processed by high powered computers to generate a
visual image of the earth's subsurface. Seismic data has been used historically
to determine drilling locations for potential oil and gas wells and more
recently it is being increasingly used in reservoir management for the
development and production of oil and gas reserves.
 
     Until recently the majority of seismic data acquisition had been
2-dimensional ("2D") in nature, where a line of geophones captured information
to generate a 2-dimensional image of the earth's subsurface structure
immediately below the geophones. In recent years there has been a significant
increase in the demand for 3-dimensional ("3D") surveys. In a 3-dimensional
survey multiple lines of geophones are combined with multiple energy sources to
generate a 3-dimensional ("3D") image of the earth's subsurface structure. As
advances have occurred in computing power, surveying techniques, geophone
systems, recording technology and acquisition techniques the industry is
undergoing a dramatic shift from 2D data acquisition to 3D data acquisition.
More comprehensive information provided by 3D surveys allows oil and gas
companies to evaluate the potential for the existence of hydrocarbon reserves
with a much higher degree of accuracy. The use of 3D surveys can significantly
increase drilling success rates and reduce the occurrence of costly dry holes
thereby lowering the cost of exploring for oil and gas. While 3D provides more
comprehensive information the cost of a 3D survey is also much greater than 2D
surveys. As a result 2D surveys remain more cost efficient for preliminary,
reconnaissance type exploratory evaluations.
 
SEISMIC OPERATIONS
 
     The Company currently operates nine land and transition zone crews in North
America; six crews in Western Canada and three crews in the Southern United
States. Channel capacity of its crews in Canada is approximately 3,100 channels
and channel capacity in the United States is approximately 1,900 channels. Three
of the Company's Canadian crews and one of the United States crews employ both
24 bit technology and telemetry transmission to transmit the seismic data from
the remote acquisition modules to the central recording unit. The telemetry
technology permit the Company to operate efficiently in marsh/swamp areas,
rivers/lakes and transition zones. The majority of data acquisition equipment
operated in North America uses cables to transmit data and these systems do not
operate as efficiently in wetland areas as do telemetry systems. Currently the
Company is the sole provider of telemetry technology in Western Canada.
 
     During fiscal 1996 one of the Company's Canadian telemetry systems was
mobilized to Pakistan and the Company performed its first project outside
continental North America. This project was completed in September 1996 and the
equipment has been returned to the Canadian marketplace.
 
                                        3
<PAGE>   4
 
     Also in December 1996 the Company acquired a set of vibroseis units. This
gave the Company, for the first time the capability of performing vibroseis
projects. The Company estimates that vibroseis projects currently account for
approximately 25% of the seismic data acquisition market in Western Canada.
 
CONTRACTS AND SIGNIFICANT CUSTOMERS
 
     Contracts for seismic data can be conducted on a turnkey or term basis or a
combination of the two. Turnkey projects are based on a fixed fee and the
Company bears substantially all of the risk of business interruption caused by
bad weather or other hazards. Turnkey projects can be more profitable to the
Company where the Company understands the cost variables associated with a
particular contract and is able to minimize productivity risk. Currently
approximately 70% of the Company's projects are conducted on a turnkey or
turnkey combined with term basis. Under the terms of the Company's contracts the
oil and gas company retain proprietary rights for the data collected by the
seismic survey.
 
     The Company markets its services to approximately 100 oil and gas companies
in Canada and approximately 50 in the United States.
 
     During fiscal 1994, 1995 and 1996, two, three and two customers each
accounted for in excess of 10% of the Company's revenues and in fiscal 1995 and
1996 the same customer accounted for 43% and 54% of the revenues respectively.
Although the projects performed by the Company were generally short term, the
inability to replace significant customers would cause the Company's revenues
and operating results to fluctuate significantly from period to period, and the
loss of certain customers would have a material adverse impact on its business.
Because of the limited number of data acquisition crews owned by the Company,
and thus the limited number of data acquisition crews that the Company is able
to deploy at any given time, the Company anticipates that a substantial portion
of future revenues will continue to be attributable to a few customers, who may
change from time to time.
 

COMPETITION
 
     The seismic data acquisition industry is highly competitive and is
characterized by constantly evolving technology and significant capital
requirements for new equipment. There are approximately 50 to 60 data
acquisition companies in North America and contracts are generally awarded to
geophysical services companies on the basis of technology, price, performance,
safety record, dependability, reputation and crew availability. The seismic data
acquisition services industry is highly competitive and several of the Company's
competitors are substantially larger than the Company, have longer operating
histories, greater financial and technical resources and larger sales volumes
than the Company.
 
WEATHER, PRODUCTIVITY AND SEASONALITY OF OPERATIONS
 
     The majority of the Company's operations are conducted under varied weather
conditions and difficult terrain, both of which could result in equipment
failures, accidents, or loss of productivity. Fixed costs, including costs
associated with operating leases, labor costs, depreciation and interest expense
account for a substantial portion of the Company's costs and expenses. As a
result downtime or low productivity resulting from reduced demand, equipment
failures, weather interruptions or otherwise, can result in significant
operating losses. The Company's operations have traditionally been highly
seasonal, with the majority of the demand for its services occurring from
November to March. The seasonality of the Company's operations is
 
                                        4
<PAGE>   5
 
primarily because oil and gas companies prefer delaying exploration activities
in Western Canada until the ground is frozen.
 
     The Company believes that the addition of telemetry technology has lessened
the risks associated with weather, low productivity and seasonality due to
diversified operating capabilities of the equipment. In addition the expansion
of operations into the United States will reduce the effect of the seasonality
associated with Canadian operations. On June 12, 1996 the Company completed the
acquisition of Boone Geophysical, Inc. ("Boone"). This acquisition consisted of
the operating assets of Boone, a seismic acquisition contractor operating in the
south eastern United States. This acquisition will assist the Company in
expanding its operations in the United States.
 
     In 1996 the Company completed an international project in Pakistan however
as a result of a loss incurred from this project the Company is refocusing on
the Canadian and U.S. markets and is not currently marketing its services
internationally.
 
SUPPLIERS
 
     The Company expects it will continue to be required to upgrade its seismic
data acquisition equipment to incorporate technological advances. The Company
obtains its seismic data acquisition equipment from a few select vendors, and in
the case of its telemetry based data acquisition systems, from a sole source
Sercel-Opseis Inc. The Company does not have long term supply contracts with any
of its suppliers and purchases its equipment on a purchase order basis. No
assurance can be given that shortages will not occur in the future or that the
sole or limited sources will be able to support the equipment requirements of
the Company. In addition there can be no assurance that the Company will not
experience delays or other supply problems that may materially adversely affect
the Company's operations or that the Company will be able to obtain suppliers in
a timely manner in the event of an increase in demand of its services. The
inability to obtain seismic data acquisition equipment as required, or to
develop alternative sources as required in the future, could materially
adversely affect the Company's business, operating results and financial
condition.
 
EMPLOYEES
 
     The number of persons employed by the Company at any given time is highly
dependent upon the time of year and availability of seismic data acquisition
projects, and typically ranges from 40 to 250 people. Although the Company does
maintain a core staff of 15 to 20 people who perform a variety of administrative
and management services, the number of additional persons employed is a function
of on-going work.
 
     None of the Company's employees are covered by collective bargaining
agreements. The Company has not experienced any work stoppages and considers its
relations with employees to be good. The Company has employment contracts with
five of its senior corporate executives.

RESULTS OF OPERATIONS
 
     Revenue increased by 50% to $14,146,971 in fiscal 1996 from $9,458,452 in
1995 which represents a 36% increase over revenues of $6,972,345 in 1994. The
increase in revenue between 1996 and 1995 was due to the following factors: a
greater number of seismic crews utilized (six in 1996 compared to five in 1995);
the acquisition of vibroseis units which enabled Venture to participate in this
segment of the industry for the first time, the acquisition of Boone
Geophysical, Inc. ("Boone") in June 1996, and the Company's participation in its
first foreign contract ("the Pakistan project") outside of North America. The
acquisition of Boone and the Pakistan project generated revenue of $1,178,367
and $1,593,825, respectively, in fiscal 1996 representing 59% of the increase.
Comparing fiscal 1994 and 1995, higher revenue resulted from the acquisition of
new equipment and the commensurate increase in the number of seismic data
acquisition systems owned or leased by the Company from four to five.
 
     Venture's direct expenses, which consist primarily of labor, drilling and
surveying costs, totaled $11,991,236 in fiscal 1996, $6,713,181 in 1995 and
$5,428,108 in 1994. These amounts reflect the Company's increasing level of
activity over the past three years, and significant costs associated with the
Pakistan operation in 1996. Overall gross margins were 15.2% in 1996, 29.0% in
1995 and 22.1% in 1994. The decrease in gross margin between 1996 and 1995 is
primarily due to a loss on the Pakistan project of $703,851, reduced margins on
Canadian based operations due to poor weather conditions in the first and second
quarters of fiscal 1996 and the temporary leasing of equipment to ensure
customer demands were met during the second quarter of fiscal 1996. The increase
in gross margin percentage between 1995 and 1994 resulted from increased
activity which diminished the effect of the fixed cost component of direct
costs, as well as a greater number of three-dimensional seismic projects which
generate higher margins than two-dimensional projects. Also 1994 direct expenses
included the cost of leasing a data acquisition system.
 
     The write down for impairment in capital assets of $100,000 in fiscal 1996
relates to the estimated realizable value on sale of capital equipment purchased
locally for the Pakistan project. With completion of
 
                                        7
<PAGE>   8
 
the project, and a determination by the Company not to pursue additional
contracts in Pakistan at this time, certain of the equipment purchased will be
sold locally since transport of the equipment to the Company's North American
markets is not economical.
 
     General and administrative expenses totaled $1,342,082 in fiscal 1996,
$825,193 in 1995 and $428,169 in 1994. The 1996 amount includes the Company's
increased marketing activities outside of Western Canada, additional personnel
costs related to the expansion of operations and the costs associated with
Venture's public company status. The increase in fiscal 1995 is mainly
attributable to the addition of management personnel to direct the Company's
expansion in North America and other international areas, as well as general
costs associated with structuring and preparing the Company for its initial
public offering early in fiscal 1996. The amount recorded in fiscal 1995 does
not reflect a compensation charge of $212,692 or $0.15 per share in connection
with the estimated fair value on transfer of common shares from an officer and
principal shareholder to another officer of the Company. The compensation charge
would have been required to comply with generally accepted accounting principles
in the United States.
 
     In fiscal 1996, 1995 and 1994 respectively, depreciation and amortization
totaled $1,513,247, $901,896 and $200,635. The increase between 1995 and 1996
reflects substantial additions to fixed assets that occurred during the period
July 1994 to July 1996. During this time, four digital telemetry data
acquisition systems, one set of vibroseis units and additional auxiliary
equipment were purchased. In the fiscal 1996 total, Venture amortized $51,440 of
goodwill related to the acquisition of Boone Geophysical, Inc. in June 1996.
Annual amortization of goodwill is expected to be approximately $154,000.
 
     Interest expense has increased from $44,742 in fiscal 1994 to $290,115 in
1995 and $327,931 in 1996. These costs have risen due to increased debt
associated with the Company's equipment purchases.
 
     The loss before income taxes of $1,022,158 has resulted in a recovery of
previously paid income taxes and a reduction in deferred income taxes. A
reconciliation of actual income tax expense as compared to expected income taxes
is provided in Note 11 of the consolidated financial statements.
 
     In fiscal 1996 the Company recorded a loss of $664,699 or $0.23 per share
as compared to net income of $436,306 or $0.31 per share in fiscal 1995 and
$515,617, or $0.38 per share, in fiscal 1994. The loss in 1996 primarily
reflects a loss on the Company's Pakistan project, costs incurred to expand its
North American operations and reduced margins associated with its Canadian based
operations. The Company has refocused its marketing and operational efforts to
the North American market and has increased personnel and equipment in
anticipation of increased demand. The decrease between fiscal 1994 and 1995
occurred due to higher general and administrative expenses, interest and
depreciation and amortization.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     At September 30, 1996 the Company had a working capital deficit of $700,720
which included an aggregate of $1,684,630 relating to the current portion of
long term debt and amounts outstanding under the Company's operating line of
credit. The Company maintains an operating line of credit which provides for an
aggregate of approximately $900,000 in advances, subject to the Company's
overall working capital position and accounts receivable. Borrowings under the
operating line are payable on demand and bear interest at the bank's prime rate
plus 0.75%. As at September 30, 1996 the Company was not in compliance with the
covenant relating to the maintenance of a working capital ratio of not less than
1:1 however the Company has subsequently requested and received a waiver from
the bank provided the Company is in compliance with the working capital covenant
by March 31, 1997.
 
     In addition to the operating line of credit and the current portion of long
term debt the Company had long term debt consisting of a capital loan and
equipment financing of $2,356,060 at September 30, 1996. Subsequent to September
30, 1996 the Company entered into an agreement whereby approximately $1,265,000
in additional funding was provided for the acquisition of additional equipment
and the Company's existing capital loan and equipment financing was refinanced
under a new capital loan (the "new capital loan"). This refinancing, which was
completed on December 20, 1996 resulted in a new capital loan of approximately
$5,140,000 ($7,000,000 Canadian). The
 
                                        8
<PAGE>   9
new capital loan bears interest at the lender's cost of funds plus 3.00% (which,
based on the lender's cost of funds at December 15, 1996 was 6.522% and is
repayable in monthly installments of approximately $103,000 plus interest over a
four year period beginning January 1997. The new capital loan is secured by all
of the Company's equipment. Subsequent to September 30, 1996 the Company entered
into an agreement to purchase one telemetry data acquisition system, one set of
vibroseis units and additional auxiliary equipment with an aggregate purchase
price of approximately $1,300,000. In addition the Company has entered into a
"lease to purchase" agreement for a second telemetry data acquisition system
whereby the Company can exercise a purchase option on April 30, 1997 with credit
being given for a portion of the lease payments incurred during the period
November 1, 1996 to April 30, 1997. The Company expects that additional
financing will have to be obtained to exercise the purchase option for the
equipment. No other significant capital expenditures are expected at this time
in fiscal 1997.
 
     In November and December 1995 the Company received net proceeds of
approximately $6,900,000 in connection with the Company's initial public
offering. These funds were primarily used to acquire additional capital
equipment and to fund the acquisition of Boone in June 1996. Capital
expenditures and the cost of the Boone acquisition aggregated approximately
$7,600,000. In accordance with the terms of the Boone acquisition agreement the
payment of $50,000 in cash and the issuance of $100,000 of common shares has
been deferred with payment to occur in three installments in fiscal 1997.
 
     Net operating cash flows provided by operating activities amounted to
$192,292, $1,960,267 and $564,005 in fiscal 1996, 1995 and 1994, respectively.
The decrease in operating cash flow in fiscal 1996 from fiscal 1995 is primarily
attributable to the loss incurred in 1996 and the reduction in non-cash working
capital. The increase in operating cash in fiscal 1995 as compared to fiscal
1994 reflects increased activity in fiscal 1995 which resulted in increased cash
generated from operations and increases in non-cash working capital.
 
     Net cash provided by financing activities in fiscal 1996 of $7,455,317 is
primarily attributable to proceeds from the Company's initial public offering
and increased debt levels. Net cash from financing activities in fiscal 1995 of
$509,306 and $2,809,263 in fiscal 1994 is primarily attributable to increased
debt levels.
 
     Cash used in investing activities of $7,647,609 in fiscal 1996 results from
capital equipment expenditures of $5,891,181 and the acquisition of Boone at a
cost of $1,756,428. Capital equipment purchases in fiscal 1996 include a set of
vibroseis units and three data acquisition systems. Cash used in investing
activities of $2,469,573 in fiscal 1995 and $3,373,268 in fiscal 1994 is
primarily attributable to the purchase of capital equipment.
 
     The Company will require satisfactory operating cash flows to continue
operations, complete capital expenditures and meet its principal and interest
obligations with respect to the new capital loan. The Company anticipates, based
on its current plans and assumptions, that the funds provided by the refinancing
and the funds expected to be generated from operations will be sufficient to
satisfy the Company's existing cash requirements in fiscal 1997. However, the
Company's ability to meet its debt service and other obligations depends on its
future performance which is subject to general economic conditions, oil and gas
commodity prices and other business factors beyond the Company's control. If the
Company is unable to generate sufficient cash flow from operations or to comply
with the terms of the new capital loan it may be required to refinance all or a
portion of its existing debt or to obtain additional financing, although there
can be no assurance that the Company will be able to obtain such refinancing or
additional financing.
 
IMPACT OF INFLATION AND CHANGING PRICES
 
     The general availability of seismic equipment and crews and the level of
exploration activity in the oil and gas industry directly affects the cost of
providing seismic data. The pricing of the Company's services is primarily a
function of these factors. The Company does not believe inflationary trends have
had any significant impact on its financial operating results for the three
years ended September 30, 1996.

                                AUDITORS' REPORT
 
To the Shareholders of
  VENTURE SEISMIC LTD.
 
     We have audited the consolidated balance sheets of Venture Seismic Ltd. as
at September 30, 1996 and 1995 and the consolidated statements of income and
retained earnings and cash flows for each of the years in the three year period
ended September 30, 1996. 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 out 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 September 30,
1996 and 1995 and the results of its operations and the changes in its financial
position for each of the years in the three year period ended September 30, 1996
in accordance with accounting principles generally accepted in Canada.

                               (IN U.S. DOLLARS)

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     These consolidated financial statements of the Company are expressed in
U.S. dollars and have been prepared in accordance with accounting principles
generally accepted in Canada, consistently applied. Because a precise
determination of many assets and liabilities is dependent upon future events,
the preparation of financial statements for a period necessarily involves the
use of estimates and approximations which have been made using careful judgment.
The consolidated financial statements have, in management's opinion, been
properly prepared within reasonable limits of materiality and within the
framework of the significant accounting policies summarized below.
 
CONSOLIDATION
 
     The consolidated financial statements include the accounts of Venture
Seismic Ltd. and its wholly-owned U.S. subsidiaries, Venture Seismic Inc.
(Texas) and Boone Geophysical, Inc. All significant intercompany transactions
have been eliminated.
 
CAPITAL ASSETS
 
     Capital assets are recorded at cost. Depreciation is provided on a
declining balance basis to amortize the cost of the assets over their estimated
economic useful lives as follows:
 
<TABLE>
                <S>                                                   <C>
                Recording equipment.................................  15% - 30%
                Equipment and radios................................     25%
                Computer equipment..................................     30%
                Automotive equipment................................     30%
                Furniture and fixtures..............................     20%
</TABLE>
 
     When capital assets are sold or scrapped, the cost of the asset and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss on disposal is reflected in income.
 
INTANGIBLE ASSETS
 
     Intangible assets consist of the excess purchase of net assets acquired and
is amortized on a straight-line basis over ten years from the date of
acquisition.
 
REVENUE RECOGNITION
 
     The Company recognizes revenue on contracts using the
percentage-of-completion method, based primarily on contract costs incurred to
date compared with total estimated contract costs to be incurred. Changes to
total estimated contract costs and full provision for losses, if any, are
recognized in the period they are determined.
 
INCOME TAXES
 
     The Company follows the deferral method of tax allocation in accounting for
income taxes under which the income tax provision is based on the income
reported in the accounts. Under this method, provision is made for income taxes
deferred principally as a result of claiming depreciation and recognizing
revenue for tax purposes at amounts that differ from those provided in the
accounts.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                               (IN U.S. DOLLARS)
                               SEPTEMBER 30, 1996
 
FOREIGN CURRENCY TRANSLATION
 
     The Company's functional (measurement) currency is the Canadian dollar. It
translates foreign currency transactions into Canadian dollars using average
exchange rates for the year for items included in the consolidated income
statement, year end exchange rates for monetary assets and liabilities and
historical rates for non-monetary assets and liabilities. Translation gains or
losses are included in income for the year.
 
     The Company has selected U.S. dollars as its currency for financial
reporting and display purposes and accordingly applies the current rate method
to translate its accounts measured in Canadian dollars to U.S. dollars. Under
this method, average exchange rates are used for items included in the
consolidated income statement and year end exchange rates for the assets and
liabilities. Any significant gains or losses are included in a cumulative
translation adjustment account as a separate component of shareholders' equity.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
     In March 1995 the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121 establishing standards for the impairment
of long-lived assets. This statement requires that long-lived assets be reviewed
for impairment whenever events or changes in circumstances indicate that the
carrying value of an asset may not realizable. The Company adopted Statement No.
121 effective September 30, 1996 and determined that there was no material
effect from this change in accounting method.
 
     In October 1995 the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123 which provides for alternative methods
for recording stock-based compensation and requires additional disclosure of the
effect on net income and earnings per share of accounting for the value of stock
options as compensation expense. The Company is required to adopt Statement No.
123 for its fiscal year ending September 30, 1997 but has not yet determined the
effect, if any, adoption will have on its financial statement disclosure.
 
2.   ADVANCES TO SHAREHOLDERS
 
     Advances to shareholders are non-interest bearing and are repayable in
annual instalments of $7,342 ($10,000 Canadian) with 18,462 common shares of the
Company pledged as collateral against the advances.
 
3.   RELATED PARTY TRANSACTIONS
 
     During fiscal 1994 the Company rented seismic equipment and purchased
equipment from 300498 Alberta Ltd. ("300498"), a company owned 50% by the
President of the Company, for $100,395 and for $326,536, respectively.

     The Company's sales are to customers in the oil and gas industry for the
acquisition of seismic data, which results in a concentration of credit risk.
The Company generally extends unsecured credit to these customers and,
therefore, the collection of these receivables may be affected by changes in
economic or other conditions and may accordingly impact the Company's overall
credit risk. Management believes the risk is mitigated by the size, reputation
and diversified nature of the companies to which they extend credit. The Company
has not previously experienced any material credit losses on the collection of
receivables.

(1) Compensation expense represents the difference between the estimated fair
     market value of $3.50 per share and the consideration given for shares
     received from a principal shareholder by a member of senior management as
     part of an employment contract. The employment contract was entered into in
     July, 1994 and contains a clause whereby the employee would receive a
     certain number of shares should certain events not occur on or before July
     1, 1995. As at September 30, 1994, management was of the opinion that these
     events would occur. In April, 1995, it became evident that these events
     would not occur and that it was probable that the employee would become
     entitled to the shares and the associated compensation expense was
     recognized in the accounts for U.S. accounting purposes.
 
     The Company paid interest of $331,970, $290,607 and $30,118 in the years
ended September 30, 1996, 1995 and 1994, respectively.
 
     The Company paid income taxes of $Nil, $400,270 and $8,331 in the years
ended September 30, 1996, 1995 and 1994, respectively.
 
     Included in Acquisition of Boone Geophysical, Inc. of $1,756,428 on the
Statement of Cash Flows, is $500,000 relating to the issuance of Venture common
shares.
 
     For the United States basis of accounting the Company has adopted FAS 109
"Accounting for Income Taxes" on a prospective basis, effective September 1,
1993. FAS 109 requires companies to recognize deferred tax assets and
liabilities for the expected future tax consequences, based on enacted rates, of
existing differences between financial reporting and tax reporting basis of
assets and liabilities. These provision also require the Company to establish a
valuation allowance for deferred tax assets where the recovery of these assets
are uncertain.
 
     The deferred tax liabilities (assets) relate to the following:

(1) Under U.S. generally accepted accounting principles the calculation of
     primary income per share is based on the number of issued and outstanding
     shares plus common share equivalents, including stock options, if they
     would have a dilutive effect. Under U.S. GAAP outstanding shares would be
     2,857,000 for 1996 and 1,400,000 for 1995 and 1994.

                                   DEBENTURE

$7,000,000.00                                           December 6, l996

1. Venture Seismic Ltd. (the "Company") for value received hereby promises to
pay to RoyNat Inc. ("RoyNat"), at its address specified above, the principal
amount of Seven Million Dollars ($7,000,000.00) in the manner hereinafter
provided, together with all other moneys which may from time to time be owing
hereunder or pursuant hereto.

2. Principal Payments.  Subject to the provisions of this Debenture, the
principal amount of this Debenture shall become due and payable by 50 monthly
instalments, each in the amount of $140,000.00, payable on the 15th day of each
month from and including January 15, l997 to and including  February 15, 2001
and the balance of the said principal amount, together with interest thereon
and all other moneys owing hereunder, shall become due and payable on the 15th
day of February, 2001.

3. Interest.  Interest shall be payable on the 15th day of each month on the
balance from time to time outstanding of the principal amount of this
Debenture, any overdue interest and any other moneys due and payable hereunder,
both before and after maturity, default or judgment, at the rate of interest
per annum (the "Loan Rate") which is 2.75% greater than RoyNat's Floating Base
Rate for the Applicable Period calculated and compounded monthly, computed from
the respective dates of advance of the moneys by RoyNat to the Company until
payment in full of all moneys owing hereunder.  RoyNat shall notify the Company
at least five days prior to each interest payment date of RoyNat's Floating
Base Rate for the Applicable Period but the non-receipt of any such notice by
the Company or the failure of RoyNat to give such notice shall in no way limit
or negate the obligation of the Company to pay interest on such payment date.
The first interest payment date shall be January 15, l997.

4. Redemption.  The Company may redeem this Debenture prior to maturity either
in whole at any time or, when not in default hereunder, in part from time to
time on not less than 30 days' written notice at a price equal to the principal
amount being redeemed plus an additional amount equal to three months' interest
on such principal amount at the Loan Rate in effect on the date fixed by the
Company for redemption and together in each case with accrued and unpaid
interest on such principal amount to the date fixed for redemption and, in the
case of redemption in whole, all other moneys owing hereunder.  The Company
shall have no other right of prepayment.

<PAGE>   3


                                     - 2 -

     Notwithstanding the foregoing paragraph, the Company may, when not in
default hereunder, on not less than 10 days' written notice, redeem up to 15% of
the principal amount outstanding on the date fixed by the Company for redemption
at a price equal to the principal amount being redeemed, together with accrued
and unpaid interest on such principal amount to the date fixed for redemption.
This right may be exercised once during each 12 month period following the date
of the initial advance of funds hereunder, and shall be non-cumulative.

4A. Conversion to Fixed Interest Rate.  The Company may at any time request
that RoyNat provide a quotation as to the availability of fixed interest rates
on the principal of this Debenture.  Within 60 days after receipt of such
request, RoyNat shall provide a written offer to the Company, offering
specified rates of interest for a selection of fixed interest periods as RoyNat
may then be able to provide and specifying a date from which the conversion
would be effective (the "Conversion Date").  Such rates of interest shall be
2.75% above RoyNat's Term Base Rate for the relevant periods.  The offer shall
stipulate any extensions of the term of this Debenture that RoyNat may require.
If the Company accepts such offer by selecting the applicable interest rate and
fixed interest period, the rate so specified and accepted shall be the "Loan
Rate" for all purposes of this Debenture from and after the Conversion Date for
the fixed interest period selected.  If such period expires before the end of
the agreed extended term, the rate of interest on this  Debenture shall revert
to the variable rate, provided in Section 3 hereof for the balance of the
agreed extended term, but the Company may thereafter avail itself again of the
provisions of this Section 4A.  The Company shall forthwith execute and deliver
such documentation, if any, as RoyNat shall request to give effect to any
interest rate conversion or extension of the term of this Debenture.  The
Company shall have no right to redeem this Debenture after conversion to a
constant interest rate except as may be specified in the offer from RoyNat
accepted by the Company, notwithstanding the provisions of Section 4 hereof.

     For the purposes of this Section:

        (a) "RoyNat's Term Base Rate", when set, shall be equal to the then
        existing Government of Canada Bond Yield for terms of 1 or 2 years plus
        .55%, and for terms of 3, 4 or 5 years plus .75%, as the case may be,
        for the fixed term selected; and

        (b) "Government of Canada Bond Yield" on any date means the yield to
        maturity, assuming semi-annual compounding, which a non-callable
        Government of Canada bond would carry if issued, in Canadian dollars in
        Canada at 100% of its principal amount on such date with a term to
        maturity equal to the fixed interest rate period being
        offered by RoyNat, as quoted to RoyNat by a money market dealer or
        Canadian Charter Bank.

5. Partial Payments.  In case less than the total principal amount of this
Debenture is redeemed at any time, the principal amount so redeemed shall be
credited against the principal payable hereunder in inverse order of maturity.

6. Security.  As security for the payment of the principal, interest and all
other moneys from time to time payable under this Debenture, and the
performance by the Company of all its obligations hereunder, but subject to
Permitted Encumbrances and to the exception as to leaseholds hereinafter
contained, the Company hereby grants a security interest in and grants,
assigns, mortgages and charges,

<PAGE>   4



                                     - 3 -

as and by way of a first, fixed and specific mortgage and charge to and in
favour of RoyNat all furniture, machinery, equipment, vehicles, accessories and
other tangible personal property (other than Inventory) now owned or hereafter
acquired by the Company, together with any proceeds of sale or disposition
thereof, and including without limitation the property described in Schedule
"B" hereto.

     And for the same consideration and purposes and subject to the same
exceptions, the Company hereby charges as and by way of a first floating charge
to and in favour of RoyNat the undertaking of the Company and all its property
and assets for the time being, both present and future, and of whatsoever
nature and wherever situate (other than property and assets from time to time
effectively subjected to the fixed and specific mortgages and charges created
hereby or by any instrument supplemental hereto).

     Provided that such floating charge shall not prevent the Company from time
to time until the security hereby constituted shall have become enforceable
from selling, leasing or otherwise disposing of the property, rights and assets
included in such floating charge or from making expenditures with a view to the
expansion of its business or from giving security constituting Permitted
Encumbrances, all in the ordinary course of its business and subject to the
provisions of this Debenture. In particular, the Company may give security to
its bankers on its Inventory or by way of assignment of its accounts receivable
(except to the extent such accounts receivable represent proceeds of the sale
or disposition of property specifically mortgaged or charged hereunder or under
any instrument supplemental hereto) and such security if validly perfected
shall rank prior to the lien hereof on such assets without further action by
RoyNat.  Notwithstanding any other provision of this Debenture except as
provided in the foregoing sentence, the security interests constituted hereby
and by any supplemental security granted to RoyNat shall not be subordinate to,
nor is there any intention to subordinate such security interests to, any
Permitted Encumbrances or security interests held by others.

     All security interests created by this Debenture attach immediately upon
execution of the Debenture.  The attachment of the floating charge has not been
postponed and the floating charge shall attach to any particular property
intended to be subject to it as soon as the Company has rights in such
property.

     All property and assets of the Company whether specifically charged or
subjected to the floating charge are hereinafter referred to as the "Mortgaged
Premises".

7. Exception as to Leaseholds.  It is hereby declared that the last day of any 
term of years reserved by any lease or sublease, verbal or written, or any 
agreement therefor, now held or hereafter acquired by the Company is excepted 
out of the Mortgaged Premises, but the Company shall stand possessed of any 
such reversion upon trust to assign and dispose thereof as RoyNat may direct.

8. Payments and Notice.  Any payments not received by RoyNat by two o'clock
p.m. on a Business Day shall be deemed to have been received on the next
Business Day.  Any notice required or desired to be given hereunder or under
any instrument supplemental hereto shall be in writing and may be given by
personal delivery, by facsimile or other means of electronic communication or
by sending the same by registered mail, postage prepaid, to RoyNat or to the
Company at their respective addresses set out above and, in the case of
electronic communication, to the facsimile numbers set out above.  Any

transmission shall be deemed to have been delivered on the Business Day
following the sending of the notice, and any notice so mailed shall be
conclusively deemed given on the third Business Day following the day of

notice shall not be given by mail. Any address for notice or payments herein
referred to may be changed by notice in writing given pursuant hereto.

             redemption of this Debenture and shall be credited against
             principal payable hereunder in inverse order of maturity;  and

        (c)  if paragraph (a) requires the reduction in an amount or amounts
             payable to RoyNat, RoyNat in its sole discretion shall determine
             which amount or amounts shall be reduced to ensure compliance with
             this Section 11.

12. Extensions and Amendments.  Any agreement for the extension of the time of

                 relating to any breach by the Company of the foregoing
                 covenants in this clause 1(o) and any breach by the Company or
                 any other person now or hereafter having an interest in the
                 Mortgaged Premises which is asserted or claimed against RoyNat.
                 This indemnity shall survive the payment in full of all amounts
                 secured hereunder and the discharge of this Debenture.  RoyNat
                 shall hold the benefit of this indemnity in trust for those
                 indemnified persons who are not parties to this Debenture.

the provisions contained in this Debenture or any default by the Company in the
observance or performance of any covenant or condition required to be observed
or performed by the Company hereunder, provided that no such waiver or any
other act, failure to act or omission by RoyNat shall extend to or be taken in
any manner to affect any subsequent breach or default or the rights of RoyNat
resulting therefrom.

3. Performance of Covenants by RoyNat.  If the Company shall fail to perform
any covenant on its part herein contained, RoyNat may in its absolute
discretion perform any such covenant capable of being performed by it.  If any
such covenant requires the payment of money or if the Mortgaged Premises or any
part thereof shall become subject to any charge ranking in priority to the lien
hereof, RoyNat may make such payment and/or pay or discharge such charge, but
shall be under no obligation to do so.  All sums so paid by RoyNat, together
with interest at the Loan Rate, shall be payable on demand and shall constitute
a charge upon the Mortgaged Premises.  No such performance or payment shall
relieve the Company from any default hereunder or any consequences of such
default.

4. Appointment of Monitor.  If in the opinion of RoyNat, acting reasonably, a
material adverse change has occurred in the financial condition of the Company,
or if RoyNat in good faith believes that the ability of the Company to pay any
of its obligations to RoyNat or to perform any other covenant contained herein
has become impaired or if an event of default has occurred, RoyNat may by
written notice to the Company, appoint a monitor (the "Monitor") to investigate
any or a particular aspect of the business and affairs of the Company for the
purpose of reporting to RoyNat.  The Company shall give the Monitor its full 
co-operation, including full access to facilities, assets and records of the 
Company and to its creditors, customers, contractors, officers, directors, 
employees, auditors and agents.  The Monitor shall not exercise any decision 
making or other management responsibilities in connection with the affairs of 
the Company.  The Monitor shall have no responsibility for the affairs of the 
Company nor shall it participate in the management of the Company's affairs.  
The Monitor shall act solely on behalf of RoyNat and shall have no contractual 
relationship with the Company as a consultant or otherwise.  The appointment 
of a Monitor shall not be regarded as an act of enforcement of this Debenture.  
All reasonable fees and expenses of the

<PAGE>   13



                                     - 6 -

Monitor shall be paid by the Company upon submission to it of a written invoice
therefor.

5. Application of Insurance Proceeds.  Any insurance moneys received by RoyNat
pursuant to clause 1(i) above may at the option of RoyNat be applied to
rebuilding or repairing the Mortgaged Premises, or be paid to the Company, or
any such moneys or any insurance moneys received by RoyNat upon the death of
any person whose life is insured under any policy of insurance assigned to
RoyNat as security for the obligations of the Company hereunder may be applied
in the sole discretion of RoyNat, in whole or in part, to the repayment of the
principal amount hereby secured or any part thereof whether then due or not,
with any partial payments to be credited against principal instalments payable
hereunder in inverse order of their maturity dates.

6. No Merger or Novation.  The taking of any judgment or the exercise of any
power of seizure or sale shall not operate to extinguish the liability of the
Company to perform its obligations hereunder or to pay the moneys hereby
secured, shall not operate as a merger of any covenant herein contained or
affect the right of RoyNat to interest at the Loan Rate in effect from time to
time hereunder, and the acceptance of any payment or other security shall not
constitute or create any novation.  The execution and delivery of this
Debenture or of any instruments or documents supplemental hereto shall not
operate as a merger of any representation, warranty, term, condition or other
provision contained in any other obligation or indebtedness of the Company to
RoyNat or under the Offer of Finance.

7. Security in Addition.  The security hereby constituted is in addition to any
other security now or hereafter held by RoyNat. The taking of any action or
proceedings or refraining from so doing, or any other dealings with any other
security for the moneys secured hereby, shall not release or affect the charges
created hereby.

8. Partial Discharges.  RoyNat may in its sole discretion grant partial
discharges in respect of any of the Mortgaged Premises on such terms and
conditions as it shall deem fit and no such partial discharges shall affect the
remainder of the security constituted hereby nor shall it alter the obligations
of the Company hereunder.
