ITEM 1. BUSINESS
 
     IRI International Corporation (including its predecessor by merger, the
"Company" or "IRI") is one of the world's largest manufacturers of land-based
drilling and well-servicing rigs and rig component parts for use in the global
oil and gas industry and is principally engaged in the design, manufacture,
service, sale and rental of onshore and offshore oilfield equipment for the
domestic and international markets. Through its IRI and Cardwell operations, the
Company designs and produces rigs to meet the special requirements of its global
clientele for service in remote areas and harsh climatic conditions. Through its
Bowen Tools Division, the Company is a leading manufacturer of downhole fishing
and drilling tools and offers a complete line of oilfield power equipment,
including top drives, power swivels, wireline and pressure control equipment and
coiled tubing systems, which complement the Company's drilling and
well-servicing rigs. The Company also manufactures and maintains a significant
inventory of replacement parts for rigs produced by the Company and by others,
enabling it to meet the needs of its customers on a timely basis. Through its
Specialty Steel Division, the Company produces premium alloy steel for
commercial and military use and for use in manufacturing oilfield equipment
products.
 
     The Company markets its oilfield equipment primarily through its own sales
force and through designated agents and distributors in every major oil and gas
producing region in the world. The Company supplements its marketing efforts by
maintaining 27 domestic sales, parts and service centers in areas of significant
drilling and production operations and 7 international parts and service
centers. The Company's network of service centers in the United States provides
its customers with refurbishment or repair services as well as ready access to
replacement parts for equipment in the field. The Company's worldwide sales and
marketing activities are closely coordinated with and supported by a staff of
more than 70 engineers and design technicians, resulting in a competitive
advantage for the Company to provide its customers with products meeting
customized design specifications for drilling and well-servicing rigs and
associated equipment.
 
     The Company's predecessor was founded in 1985 through the combination of
Ingersoll-Rand Oilfield Products Company and the Ideco Division of Dresser
Industries, Inc. and was acquired by an affiliate of the Company's current
stockholders in 1994. The Company acquired the business and operations of the
Bowen Tools Division (the "Bowen Acquisition") on March 31, 1997 and Cardwell
International, Ltd. (the "Cardwell Acquisition") on April 17, 1997 (together,
the "Acquisitions").
 
DRILLING AND WELL-SERVICING RIGS
 
  Products
 
     The Company designs, constructs and sells a total of 48 standard models of
drilling and well-servicing rigs which utilize component parts manufactured by
the Company under the IDECO(R), FRANKS(R), CARDWELL(TM) and IRI(TM) brand names.
The Company's products include (i) land-based skid mounted rigs, (ii) offshore
drilling and well-servicing rigs, (iii) self-propelled drilling and
well-servicing rigs, (iv) slant hole drilling rigs and (v) heli-rigs. In
addition to the standard models, the Company manufactures customized drilling
and well-servicing rigs to customer specifications to accommodate, among other
things, extreme weather conditions, moving systems or hook load capacities. The
Company also designs, manufactures and sells component products used in the
original construction, modernization or repair of land and offshore rigs,
including masts, derrick, substructures and other components used in hoisting,
power transmission, pumping and mud systems. The sale of drilling and
well-servicing rigs and component parts accounted for $74.2 million of the
Company's revenues for the year ended December 31, 1997.
 
  Competition
 
     The Company's revenues and earnings are affected by the actions of
competitors, including price changes, introduction of new or improved products
and changes in the supply of, and improvements in the deliverability of,
competing products. The Company's principal competitors in the manufacture of
drilling rigs and components are National-Oilwell, Inc., Continental Emsco
Company and Varco International, Inc.
 
                                        2
<PAGE>   3
 
  Backlog
 
     Sales of the Company's drilling and well-servicing rigs are made almost
exclusively on the basis of written purchase orders or contracts. The Company
includes in its rig backlog those orders or purchase commitments which
management believes to be reasonably certain of consummation based on industry
practice, the historical relationship between the Company and the customer or
the financial terms of the sale, including cash advances, letters of credit or
similar credit support arrangements. The total value of its rig backlog of the
Company as of December 31, 1997 and 1996 was $69.4 million and $12.7 million,
respectively. No assurance can be given that contracts included in the Company's
backlog will ultimately generate anticipated revenues in the period expected or
otherwise.
 
     The Company attempts to mitigate certain financial risks in sales to
customers by requiring, where commercially feasible, cash advances, irrevocable
letters of credit or similar credit support arrangements. As of December 31,
1997, the Company has received approximately $7.5 million in cash down payments
and approximately $2.6 million of letters of credit or assignments of letters of
credit to support customer orders.
 
  Raw Materials
 
     The Company's manufacturing operations require a variety of components,
parts and raw materials which the Company purchases from multiple commercial
sources. The Company believes that the loss of any of its suppliers would not
have a material adverse effect on the Company's operations.
 
FISHING AND DRILLING TOOLS
 
     Through Bowen, the Company designs, manufactures, sells and rents fishing
and drilling tools under the BOWEN(R) brand name. Fishing and drilling tools
manufactured by the Company include (i) external and internal catch fishing
tools, (ii) junk catch fishing tools, (iii) milling and cutting tools, (iv)
accessory tools such as jars, jar intensifiers and bumper subs and (v) repair
and remedial tools. Fishing and drilling tool sales and rentals accounted for
$47.8 million of the Company's revenues for the year ended December 31, 1997.
 
  Competition
 
     In the fishing and drilling tool business, like the rig manufacturing
business, the Company's revenues and earnings can be affected by actions of
competitors, including price changes, the introduction of new products or
improved products and changes in supply of, and improvements in the
deliverability of, competing products. The Company's primary competitors in the
manufacture of fishing tools are Gotco International Inc. and Houston Engineers
Inc. In the drilling tool market, the Company's primary competitors are Houston
Engineers Inc. and Dailey Corporation.
 
POWER AND WIRELINE/PRESSURE CONTROL EQUIPMENT
 
  Power Equipment
 
     The Company, through its Bowen Tools Division, manufactures products for
the power equipment market, including power-swivel systems used in
well-servicing and drilling applications, portable top drive drilling systems,
power subs, bucking units, power tongs and coiled tubing systems. Sales and
rentals of power equipment products accounted for $12.4 million of the Company's
revenues for the year ended December 31, 1997.
 
     The market for top drive drilling systems is very competitive. Competition
is based on product design and quality, ability to meet delivery requirements
and pricing. The Company's principal competitor in this segment is Tesco
Corporation. In addition, the Company's portable top drive drilling systems
compete with products manufactured by Maritime Hydraulics US, Inc., Canrig Ltd.
and Varco International, Inc.
 
                                        3
<PAGE>   4
 
  Wireline/Pressure Control Equipment
 
     The Company manufactures products in this group under the BOWEN(R) brand
name. The products include small blowout preventers, unions, tool traps, tool
catchers, lubricator risers, control heads, stuffing boxes and wellhead
adapters.
 
     The market for pressure control equipment is very competitive. Competition
is based on product design, quality, ability to meet delivery requirements and
pricing. The Company's principal competitors in the market include Hydrolex,
Inc., Elmar Ltd. and Texas Oil Tools.
 
REPLACEMENT PARTS AND REFURBISHMENT
 
     The Company manufactures and maintains a significant inventory of
replacement parts and replacement components. The Company also refurbishes older
rigs for its customers. The Company believes that the replacement parts and
refurbishment businesses will grow significantly over the next several years as
a result of increased worldwide rig utilization and the age of the international
rig fleet, which was generally constructed prior to 1982. The Company believes
it is well positioned to provide replacement parts and refurbishment services as
a result of the large number of operating rigs manufactured under the Company's
brand names and the preference of equipment owners to obtain replacement parts
and refurbishment services from the original manufacturer. Replacement parts and
refurbishment accounted for $32.3 million of the Company's revenues for the year
ended December 31, 1997.
 
SPECIALTY STEEL PRODUCTS
 
     Through its Specialty Steel Division, the Company manufactures premium
specialty steel forgings for commercial and military use and for use in
manufacturing oilfield equipment products. Specialty steel products accounted
for $13.5 million of the Company's revenues for the year ended December 31,
1997.
 
     The Company manufactures over 100 different alloys to form forged products
in round, square and rectangular solid, trepanned, counter bored and stepped
forms to meet customer specifications. The Company sells its specialty steel
products primarily to customers in the heavy equipment, aircraft, petroleum and
power generation industries in North America and to the United States military.
Specialty steel products are also sold as feedstock directly to forgers and
extruders. The Division's largest customer accounted for 28.1% of the Division's
revenue for the year ended December 31, 1997. In addition, 13.9% of production
for 1997 was sold to the government and military sectors.
 
  Raw Materials
 
     Raw materials used to manufacture specialty steel products consist of
premium steel scrap and various alloys, of which the Company believes there is
an adequate supply in the North American market.
 
  Competition
 
     The U.S. specialty steel market is highly competitive due primarily to the
high cost of freight associated with moving small amounts of high tonnage
finished goods. Competitive factors include price, delivery, quality and
service. Steel ingots and billets are commodities and are extremely price
competitive. The Company's major competitors in the specialty steel market are
National Flame and Forge Company Inc., Ellwood Group Inc., Scot Forge Company
Inc., Erie Forge and Steel Inc., First Miss Steel Inc. and British Steel PLC.
 
ENGINEERING AND PRODUCT DEVELOPMENT
 
     The Company maintains a staff of more than 70 engineers and design
technicians to (i) design and test new products, components and systems for use
in manufacturing and drilling applications, (ii) enhance the capabilities of
existing products and (iii) assist the Company's sales organization and
customers with special requirements and products. The Company intends to
continue its research, engineering and product development programs to develop
proprietary products that are complementary to the Company's existing products,
particularly with respect to harsh environment rigs and equipment. The Company's
total engineering
                                        4
<PAGE>   5
 
and product development expenses for the year ended December 31, 1997 were $4.3
million, which includes the Bowen and Cardwell expenses only since the dates of
their respective acquisitions. The Company has budgeted $7.1 million for
engineering and product development expenses for 1998.
 
MARKETING, SALES AND DISTRIBUTION
 
     The Company markets its oilfield products primarily through its own sales
force and through designated agents and distributors in every major oil and gas
producing region in the world. The Company's customers include international and
domestic drilling contractors and international and domestic oil and gas
exploration and production companies, including foreign state-owned oil and gas
enterprises. The Company supplements its marketing efforts by maintaining 27
domestic sales and service centers in areas of significant drilling and
production operations and 7 international parts and service centers.
 
     See Note 13 to the Consolidated Financial Statements for financial
information related to the Company's revenues by geographic region.
 
INTELLECTUAL PROPERTY
 
     The Company owns or has license to use a number of U.S. and foreign patents
covering a variety of products. Although in the aggregate the patents are of
importance to the Company, the Company does not consider any single patent to be
essential. In general, the Company depends upon product name recognition,
manufacturing quality control and application of its expertise rather than
patented technology in the conduct of its business. The Company enjoys product
brand name recognition, principally through its BOWEN(R), IDECO(R), FRANKS(R),
CARDWELL(TM), and IRI(TM) trademarks, and considers such trademarks to be
important to its business.
 
EMPLOYEES
 
     As of December 31, 1997 the Company employed a total of 1,489 persons, of
whom 30 were employed outside the United States. Approximately 30% of these
employees were salaried and the balance were compensated on an hourly basis.
Approximately 23% of the Company's employees are represented by a union or are
parties to a collective bargaining agreement, which is effective for the period
from July 1997 until July 2000, covers approximately 340 employees and contains
customary provisions with respect to wages, hours and working conditions for
certain production and maintenance employees in the Bowen Tools Division. The
wage rates governing the first year of the contract represented a 4.5% increase
over the rates previously in effect, and the agreement provides for further 3%
increases in each of the second and third year thereof. The Company considers
its relations with its employees to be good.
 
RISKS AND INSURANCE
 
     The Company's operations are subject to the usual hazards inherent in
manufacturing products and providing services for the oil and gas industry.
These hazards can cause personal injury and loss of life, business
interruptions, property and equipment damage and pollution or environmental
damage. The Company maintains comprehensive insurance covering its assets and
insuring against risks at levels which management believes to be appropriate and
in accordance with industry practice. No assurance can be given, however, that
insurance coverage will be adequate in all circumstances or against all hazards
or risks, or that the Company will be able to maintain adequate insurance
coverage in the future at commercially reasonable rates or on acceptable terms.
 
     The Company's services and products are used in drilling, production and
well-servicing operations which are subject to inherent risks that could result
in property damage, personal injury, suspension of operations or loss of
production. The Company maintains product liability and worker's compensation
insurance. Although the limits of its insurance coverage against an accident are
generally in accordance with industry practice, such insurance may not be
adequate to protect the Company against liability or losses accruing from all
the consequences of such an incident.
 
                                        5

ENVIRONMENTAL MATTERS
 
     The manufacture of oilfield equipment and specialty steel products is
subject to a broad range of federal, state and local environmental laws and
regulations, both in the United States and in foreign jurisdictions, including
those governing discharges into the air and water, the handling and disposal of
solid and hazardous wastes and the remediation of soil and groundwater
contaminated by petroleum products or hazardous substances or wastes
(collectively referred to as "Environmental Laws"). It has been the Company's
policy to eliminate and minimize generation of wastes at its facilities through
plant operations, process design and maintenance. The Company continually
strives to reduce wastes by sending these materials off-site for recycling
and/or reuse. The Company has taken and continues to take into account the
requirements of such environmental laws and regulations in the improvement,
modernization, expansion and start-up of its facilities, and believes that it is
currently in substantial compliance with such laws and regulations. As is the
case with most industrial manufacturers, the Company could incur significant
costs related to environmental compliance in the future. No assurance can be
given that the Company will not be required to incur significant costs in the
future for remediation of existing conditions at company's facilities or
modifications to company operations that may be required by Environmental Laws.
These potential costs may have a material adverse effect on the Company's
financial condition and results of operations.
 
     The Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA") imposes liability without regard to fault, on certain classes of
persons with respect to the release of a hazardous substance into the
environment. These persons include the owner and operator of the disposal site
or sites where the release occurred and companies that disposed or arranged for
the disposal of the hazardous substances found at such site. Persons who are
responsible for releases of hazardous substances under CERCLA may be subject to
joint and several liability for the costs of cleaning up the hazardous
substances that have been released into the environment and for damages to
natural resources, 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 hazardous substances released into the environment.
 
     The Company currently owns or leases, and has in the past owned or leased,
numerous properties that for many years have been used for the manufacture and
storage of products and equipment containing or requiring oil and/or hazardous
substances. Although the Company has utilized operating and disposal practices
that were standard in the industry at the time, hydrocarbons or other wastes may
have been disposed of or released on or under the properties owned or leased by
the Company or on or under other locations where such wastes have been taken for
disposal. In addition, many of these properties have been operated by third
parties whose treatment and disposal or release of hydrocarbons or other wastes
was not under the Company's control. These properties and the wastes disposed
thereon may be subject to CERCLA, the Resource Conservation and Recovery Act and
analogous state laws. Under such laws, the Company could be required to remove
or remediate previously disposed wastes (including groundwater contamination) or
to perform remedial operations to prevent future contamination.
 
     Various federal, state and local laws, regulations and ordinances govern
the removal, encapsulation or disturbance of asbestos containing materials
("ACM"). Such laws and regulations may impose liability for the release of ACMs
and may provide for third parties to seek recovery from owners or operators of
facilities at which ACM was or is located for personal injury associated with
exposure to ACM. The Company is aware of the presence of ACM at its facilities,
but it believes that such material is in acceptable condition at this time. The
Company believes that any future costs related to remediation of ACM at these
sites will not be material, either on an annual basis or in the aggregate,
although there can be no assurance with respect thereto.
 
     The Company has sought to reduce the impact of costs arising from or
related to actual or potential environmental conditions at the Bowen Tools
Division facilities caused or created by Bowen or its predecessors in title
through the Company's contractual arrangements with Air Liquide America
Corporation ("Air Liquide"). Pursuant to such arrangements, Air Liquide and
Bowen agreed to indemnify the Company for such costs. Air Liquide provided the
Company with certain environmental assessments with respect to most of the Bowen
properties conveyed to the Company. In some cases, these initial assessments
recommended the performance of further investigation to evaluate the need for
and to determine the extent of the removal or
 
                                        6
<PAGE>   7
 
remediation of hazardous substances required to address historical operations of
Bowen. Air Liquide is conducting a further environmental review of the Bowen
Tools Division facilities to determine the potential scope of remediation to be
conducted at such facilities by Air Liquide or Bowen. There can be no assurance
that Air Liquide or Bowen will meet its obligations under the indemnification
arrangements or that there will not be future contamination for which the
Company might be fully liable and that may require the Company to incur
significant costs that could have a material adverse effect on the Company's
financial condition and results of operations.
 
     Although the Company believes that it is in substantial compliance with
existing environmental laws and regulations, there can be no assurance that
substantial costs for compliance will not be incurred in the future. Moreover,
it is possible that other developments, such as stricter environmental laws,
regulations and enforcement policies thereunder, could result in additional,
presently unquantifiable, costs or liabilities to the Company.
 
HITEC TRANSACTION
 
     On March 8, 1998, the Board of Directors of the Company and of Hitec ASA, a
Norwegian Corporation ("Hitec"), approved a transaction (the "Hitec
Transaction") whereby the businesses of the Company and Hitec will be combined
and the resulting company will be named "IRI Hitec, Inc." Pursuant to the Hitec
Transaction, Hitec Shareholders will receive 0.5748 of a newly issued share of
IRI Common Stock for each common share of Hitec. The Hitec Transaction is
subject to, among other things, the approval of the Company's stockholders and
the tender of at least 90% of Hitec's outstanding common shares. In connection
with the Hitec Transaction, the Company's principal stockholder, Hushang Ansary,
agreed to vote the shares of IRI Common Stock beneficially owned by him (which
shares constitute a majority of the shares issued and outstanding) in favor of
the Hitec Transaction. In addition, pursuant to the Hitec Transaction each of
Arve Johnsen, Chairman of the Board of Hitec, and Jon Gjedebo, Chief Executive
Officer of Hitec, agreed to tender the shares of Hitec common shares
beneficially owned by them to the Company (which shares in aggregate represent
approximately 27.3% of the outstanding Hitec common shares.)
 
     Hitec is engaged primarily in the design and engineering of advanced
technology for the offshore oil and gas industry. See Item 7 "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

     The Company also owns or leases facilities at 34 domestic and international
locations, substantially all of which are sales, service or warehouse locations.
 
ITEM 3. LEGAL PROCEEDINGS
 
     There are pending or threatened against the Company various claims,
lawsuits and administrative proceedings all arising from the ordinary course of
business with respect to commercial product liability and employee matters which
seek remedies or damages. Although no assurance can be given with respect to the
outcome of these or any other pending legal and administrative proceedings and
the effects such outcomes may have on the Company, management believes that any
ultimate liability resulting from the outcome of such proceedings to the extent
not otherwise provided for will not have a material adverse effect on the
Company's consolidated financial statements.
 
     The Company maintains comprehensive liability insurance. The Company
believes such coverage to be of a nature and amount sufficient to ensure that it
is adequately protected from any material financial loss as a result of such
claims. The Company currently is not the subject of any legal actions for which
it is neither insured nor indemnified and which the Company believes will
individually or in the aggregate have a material adverse effect on the Company's
financial condition, results of operations or liquidity, nor to the Company's
knowledge is any such litigation threatened.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     The number of record holders of the Company's Common Stock as of March 17,
1998 was 64. Pursuant to the Company's Incentive Plan, 1,933,000 shares of the
Common Stock are subject to outstanding options at March 17, 1998.
 
     The Company has never declared or paid cash dividends on its capital stock.
The Company currently expects to retain future earnings to provide for the
continual growth and development of the Company's business.
 
     During 1997, the Company made no sales of equity securities not registered
under the Securities Act of 1933.
 
     On November 19, 1997, the Company and certain of its stockholders (the
"Selling Stockholders") completed the sale of 13,800,000 shares of Common Stock
(after exercise of options granted to the underwriters' to cover overallotments)
at a per share price of $18.00 in a firm commitment underwritten initial public
offering pursuant to a Registration Statement on Form S-1 which was declared
effective on November 12, 1997 (the "Offering"). The managing underwriters for
the Offering were Lehman Brothers Inc., Credit Lyonnais Securities (USA) Inc.,
Howard, Weil, Labouisse, Friedrichs Incorporated and Prudential Securities
Incorporated. Of the $248,400,000 in aggregate proceeds raised in connection
with the offering, (i) $16,698,000 was paid to the underwriters in connection
with underwriting discounts, (ii) $65,481,000 in aggregate net proceeds were
received by the Selling Stockholders, (iii) $166,221,000 in net proceeds was
received by the Company and (iv) approximately $2,284,000 was paid by the
Company in connection with expenses, including legal, printing and filing fees,
in connection with the offering. There were no direct or indirect payments to
directors or officers of the Company. Approximately $110,000,000 of the net
proceeds from the offering were used by the Company to repay certain outstanding
indebtedness as follows:
 
          (i) $31.0 million to redeem the Senior Notes (as defined herein) in
     full;
 
          (ii) $64.0 million to repay in full the principal amount outstanding
     under the Term Loan (as defined herein); and
 
          (iii) $15.0 million to repay all amounts then outstanding under the
     Revolving Credit Facility (as defined herein).
 
     The Company is currently investing the remaining net proceeds from the
offering for future use as additional working capital. Such remaining net
proceeds have been invested in highly liquid instruments with an average
maturity of six months or less, such as commercial paper and U.S. Treasury
bills, and marketable securities.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
     The following discussion and analysis of the Company's financial condition
and results of operations should be read in conjunction with "Selected
Consolidated Financial Information," the Consolidated Financial Statements and
Notes thereto and the other information included elsewhere in this Annual Report
on Form 10-K.
 
OVERVIEW
 
  General
 
     The Company manufactures land-based drilling and well-servicing rigs and
rig component parts for use in the domestic and international markets. The
Company's revenues are substantially dependent upon the condition of the oil and
gas industry and worldwide levels of exploration, development and production
activity, including the number of oil and gas wells being drilled, the depth and
drilling conditions of such wells, the number of well completions and the level
of workover activity. Exploration, development and production activity is
largely dependent on the prevailing view of future oil and natural gas prices
which have been characterized by significant volatility over the last 20 years.
Oil and natural gas prices are influenced by numerous factors affecting the
supply of and demand for oil and gas, including the level of drilling activity,
worldwide economic activity, interest rates and the cost of capital,
environmental regulation, tax policies, political requirements of national
governments, coordination by OPEC and the cost of producing oil and gas. Demand
for the Company's products in certain emerging market countries may depend
somewhat less on the prevailing view of future oil and natural gas prices as
such countries may generally place greater emphasis on their need for internal
development, energy self-sufficiency or hard currency earnings.
 
     The Company has achieved significant growth in recent years, taking
advantage of the favorable industry climate. The Company's revenues were $36.7
million, $52.5 million, $75.7 million and $185.4 million, respectively, in the
fiscal year ended March 31, 1995 (which included the results of operations of
the Company's predecessor from April 1, 1994 through September 19, 1994), for
the year ended March 31, 1996, for the twelve month period ended December 31,
1996 and for the year ended December 31, 1997. Operating income for the same
periods was $2.0 million, $7.6 million, $11.8 million and $22.6 million,
respectively. As discussed below, the Company Acquisition (as defined below) was
recorded using the purchase method of accounting, making operating income for
the fiscal year ended March 31, 1995 not comparable to operating income for
later periods.
 
     An important component of the Company's growth strategy has been, and will
continue to be, to evaluate and, where feasible, make strategic acquisitions
that (i) strengthen the Company's market share for existing products, (ii)
diversify the Company's product lines in key business segments or (iii) increase
the Company's geographic diversity. In furtherance of these strategies, the
Company recently acquired the businesses and operations of Bowen and Cardwell
and has agreed to a combination with Hitec. See "-- Acquisitions and Capital
Expenditures" and "Hitec Transaction."
 
     The Hitec Transaction will, in management's judgment, bring to the Company
an important line of products used for the offshore exploration and production
of oil and gas, as well as significant related engineering and product
development capability. This will complement the Company's existing product
lines, which are used principally for land-based drilling and well-servicing
applications. In addition, management believes that having the ability to serve
the offshore market as well as its traditional onshore customers with higher
technology products and services will give the Company an increased ability to
withstand a moderation of or reduction in the worldwide levels of exploration,
development and production activity.

  Foreign Exchange Transactions
 
     Sales denominated in currencies other than U.S. dollars are made only by
the Bowen Tools Division. The Company attempts to limit its exposure to foreign
currency fluctuations by limiting the amount of sales denominated in currencies
other than U.S. dollars and by, with the exception of the Company's Canadian
subsidiary, maintaining its cash and cash equivalents in U.S. dollar denominated
accounts and investments (except to the extent needed for local operating
expenses). For the years ended December 31, 1996 and 1997, Bowen's Canadian
sales (expressed in U.S. dollars) were $4.2 million and $4.4 million,
respectively, and all other non-U.S. dollar denominated sales (expressed in U.S.
dollars) were $9.1 million and $7.4 million, respectively. The Company has not
engaged in and does not currently intend to engage in any significant hedging or
currency trading transactions designed to compensate for adverse currency
fluctuations among foreign currencies.
 
  Negative Goodwill
 
     On September 20, 1994, all of the outstanding stock of the Company was
acquired by an affiliate of the Selling Stockholders for $5.0 million in cash
(the "Company Acquisition"). The Company Acquisition was recorded using the
purchase method of accounting and the purchase price allocated to the assets
acquired and liabilities assumed based upon their estimated fair values at the
date of the Company Acquisition. The excess of the fair value of net assets
acquired over the consideration paid was applied against nonmonetary assets
(property, plant and equipment), reducing the balances of these assets at the
date of the Company Acquisition to zero, and the remaining excess of the fair
value of net assets acquired over consideration paid was recorded as negative
goodwill. The purchase price has been allocated to the assets acquired and
liabilities assumed based up on their fair values at the date of the
acquisition. Negative goodwill of $26.8 million is being amortized using the
straight-line method over five years ending September 19, 1999. The
comparability of the results of operations between the years ended March 31,
1995 (which included the results of operations of the Company's predecessor from
April 1, 1994 to September 19, 1994) and March 31, 1996 is affected by, in
addition to the amortization of negative goodwill (which reduces the
post-Company Acquisition cost of sales), the exclusion of depreciation expense
related to fixed assets written down to zero on the Company Acquisition date,
both of which have a positive effect on earnings. See Note 1 to the Consolidated
Financial Statements. Amortization of negative goodwill decreased cost of goods
sold by $5.4 million in each of the year ended December 31, 1997, the twelve
month period ended December 31, 1996 and the year ended March 31, 1996 and $2.7
million for the period from September 20, 1994 through March 31, 1995.
 
RESULTS OF OPERATIONS
 
     In June 1997 the Company changed its fiscal year from a March 31 year-end
to a December 31 year-end, effective with the period ended December 31, 1996, in
order to harmonize the fiscal years of IRI, Cardwell and Bowen. The following
discussion of the results of operations of the Company's business units does not
reflect allocation of corporate overhead expense, unallocated administrative
expense or amortization of goodwill and negative goodwill. See Note 1 to the
Company's Financial Statements for a presentation of segment information.
 
     Sales of new rigs manufactured by the Company can produce large
fluctuations in revenues depending on the size and the timing of the
construction of orders. Individual orders of rig packages range from $1 million
to $25 million and cycle times for the design, engineering and manufacturing or
rig packages range from six to nine months. These fluctuations may affect the
Company's quarterly revenues and operating income.
 
     The lack of material tax provisions for the historical periods discussed
below results primarily from (i) the amortization of negative goodwill which
does not give rise to taxable income and (ii) the availability of net operating
loss carry forwards. As discussed above, negative goodwill is being amortized
over five years ending September 19, 1999. See "-- Negative Goodwill." See Note
9 to the Company's Consolidated Financial Statements for a discussion of the
Company's net operating loss carry forwards.

  Results of Segment Operations
 
     The following discussion of the results of operations of the Company's
oilfield equipment, downhole tools and specialty steel segments does not reflect
the allocation of corporate and unallocated administrative expenses,
amortization of negative goodwill and amortization of goodwill on an individual
segment basis. Certain information that reconciles the discussion of the results
of operations of the individual segments to the Company's Consolidated Financial
Statements is as follows:

TWELVE MONTHS ENDED DECEMBER 31, 1997 COMPARED TO TWELVE MONTHS ENDED DECEMBER
31, 1996
 
  Oilfield Equipment
 
     Revenues and operating income for the oilfield equipment unit were $106.5
million and $15.6 million, respectively, for the twelve months ended December
31, 1997, as compared to $61.5 million and $9.9 million, respectively, for the
twelve months ended December 31, 1996. For the twelve months ended December 31,
1997, revenues and operating income reflect contributions thereto by Cardwell of
$30.0 million and $4.5 million. The increase in revenues resulted from the
Cardwell Acquisition and increased sales of rig packages by the IRI Division.
Increased operating income resulted from the IRI Division's increased sales in
the period. Gross margin for the twelve months ended December 31, 1997 was
18.4%, as compared to 22.1% for the twelve month period ended December 31, 1996.
This decrease resulted principally from the inclusion of Cardwell's operations
(gross margin of 14.9%) in the results for the twelve months ended December 31,
1997. Cardwell's comparatively lower gross margin resulted from lower margin rig
manufacturing contracts entered into prior to the date of the Cardwell
Acquisition, the pricing terms of which reflected Cardwell's lower fixed
overhead cost structure. The Company has implemented a uniform pricing policy
that the Company believes will result in higher overall gross margins.
 
  Downhole Tools
 
     The Company acquired the Bowen Tools Division on March 31, 1997 and prior
to such date the Company had no downhole tools unit. Revenues and operating
income for the Bowen Tools Division were $67.2 million and $11.9 million,
respectively, for the nine months ended December 31, 1997, as compared to $52.3
million and $5.7 million, respectively, for the nine months ended December 31,
1996. Increased revenues and operating income at the Bowen Tools Division were
primarily attributable to increased drilling activity in the U.S. Gross margin
for the nine months ended December 31, 1997 was 26.5%, as compared to
 
                                       13
<PAGE>   14
 
24.0% for the nine months period ended December 31, 1996. The increase in gross
margin was primarily due to improved pricing, increased volume and more
efficient capacity utilization.
 
  Specialty Steel
 
     Revenues and operating income for the specialty steel unit were $13.5
million and $4.5 million, respectively, for the twelve months ended December 31,
1997, as compared to $14.1 million and $3.5 million, respectively, for the
twelve months ended December 31, 1996. The decrease in revenues was primarily
the result of reduced demand from a major customer. Gross margin for the twelve
months ended December 31, 1997 was 33.4%, as compared to 26.2% for the twelve
months ended December 31, 1996. The increase in gross margin was primarily due
to improved pricing and more efficient capacity utilization.
 
  Corporate Administrative and Interest Expenses
 
     Corporate administrative expenses were $13.9 million for the twelve months
ended December 31, 1997, as compared to $7.0 million for the twelve months ended
December 31, 1996. The increase was due primarily to the inclusion of Bowen and
Cardwell's administrative expenses of $3.2 million and $1.2 million,
respectively, for the 1997 period.
 
     Interest expense increased from $0.6 million for the twelve months ended
December 31, 1996 to $8.8 million for the twelve months ended December 31, 1997.
The increase in interest expense is a result of (i) borrowings on March 31, 1997
under a $65.0 million five-year term loan (the "Term Loan") provided to the
Company by certain financial institutions, as lenders, Credit Lyonnais New York
Branch, as a lender and as administrative agent, and Lehman Commercial Paper
Inc., as a lender and as advisor, manager and syndication agent (collectively,
the "Lenders"), and the issuance of $31.0 million aggregate principal amount of
Senior Subordinated Increasing Rate Notes (the "Senior Notes") on such date to
fund the Acquisitions and (ii) borrowings under a $25.0 million three-year
revolving credit facility between the Company and the Lenders with a $20 million
sublimit for the issuance of letters of credit (the "Revolving Credit Facility")
during the period to fund working capital requirements of Cardwell.
 
NINE MONTHS ENDED DECEMBER 31, 1996 COMPARED TO NINE MONTHS ENDED DECEMBER 31,
1995
 
  Oilfield Equipment
 
     Revenues and operating income for the oilfield equipment unit were $52.0
million and $7.4 million, respectively, for the nine month period ended December
31, 1996, as compared to $30.7 million and $1.6 million, respectively, for the
nine month period ended December 31, 1995. The increases in revenues and
operating income were primarily attributable to an increase in sales of the
Company's oilfield equipment products to exploration and production companies
and contract drillers. The elevated levels of sales of the Company's products
reflected the increased oil and gas exploration and production activity
worldwide. Gross margin for the nine month period ended December 31, 1996 was
19.7% compared to 13.7% for the nine month period ended December 31, 1995, as a
result of price increases, greater fixed overhead absorption and more efficient
capacity utilization due to increased manufacturing volume.
 
  Specialty Steel
 
     Revenues and operating income for the specialty steel unit were $10.3
million and $2.9 million respectively, for the nine month period ended December
31, 1996, as compared to $8.5 million and $2.0 million, respectively, for the
nine month period ended December 31, 1995. The increases in revenues and
operating income were primarily the result of increased sales to steel service
centers and a major customer. Gross margin for the nine month period ended
December 31, 1996 was 29.9%, as compared to 24.8% for the nine month period
ended December 31, 1995, as a result of more efficient capacity utilization.
 
  Corporate Administrative and Interest Expenses
 
     Corporate administrative expenses were $5.2 million, representing 8.3% of
revenues, for the nine month period ended December 31, 1996 and $2.7 million,
representing 6.9% of revenues, for the nine month period
 
                                       14
<PAGE>   15
 
ended December 31, 1995. The higher levels of expense were a consequence of
establishing a corporate headquarters in Houston, Texas, and expanding the
Company's management team and related support personnel.
 
     Interest expense was $0.6 million for the nine month period ended December
31, 1996, compared to $0.2 million of interest income for the nine month period
ended December 31, 1995, due to borrowings by the Company under a former credit
facility established in April 1996. The funds borrowed were used by the Company
to fund increased working capital needs necessitated by the increases in the
orders for its oilfield equipment products during the nine month period ended
December 31, 1996.
 
YEAR ENDED MARCH 31, 1996 COMPARED TO YEAR ENDED MARCH 31, 1995
 
     The Company Acquisition was recorded using the purchase method of
accounting and the purchase price was allocated to the assets acquired and
liabilities assumed based upon their estimated fair values at the date of the
acquisition. See Note 1 to the Consolidated Financial Statements.
 
  Oilfield Equipment
 
     Revenues and operating income for the oilfield equipment unit were $40.2
and $4.1 million, respectively, in the fiscal year ended March 31, 1996,
compared to $27.0 million and $0.6 million, respectively, in the fiscal year
ended March 31, 1995 (which included the results of operations of the Company's
predecessor from April 1, 1994 to September 19, 1994). This increase was due
primarily to an increase in sales of the Company's oilfield equipment products
to exploration and production companies and contract drillers, resulting from
the increase in oil and gas production activities worldwide and management's
focus on expanding the Company's international marketing activities and sales
and reductions in overhead and labor costs subsequent to September 19, 1994.
 
  Specialty Steel
 
     Revenues and operating income for the specialty steel unit were $12.3
million and $2.6 million, respectively, in the fiscal year ended March 31, 1996,
compared to $9.7 million and $1.5 million, respectively, in the fiscal year
ended March 31, 1995 (which included the results of operations of the Company's
predecessor from April 1, 1994 to September 19, 1995). This increase was
primarily due to increased sales to a major customer as well as increased
military and commercial sales and reductions in overhead and labor costs
subsequent to September 19, 1994.
 
ACCOUNTING POLICIES
 
     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which establishes standards for reporting and display of comprehensive
income in a full set of general-purpose financial statements. Comprehensive
income includes net income and other comprehensive income which is generally
comprised of changes in the fair value of available-for-sale marketable
securities, foreign currency translation adjustments and adjustments to
recognize additional minimum pension liabilities. This Statement is effective
for fiscal years beginning after December 15, 1997. The Company believes the
adoption of this Statement will not have a material effect on its financial
statements.
 
     In June, 1997, the FASB issued SFAS No. 131. "Disclosures about Segments of
an Enterprise and Related Information," which establishes standards for the way
that public business enterprises report information about operating segments in
annual financial statements and requires that those enterprises report selected
information about operating segments in interim financial reports issued to
stockholders. It also establishes standards for related disclosures about
products and services, geographic areas and major customers. This Statement is
effective for financial statements for periods beginning after December 15,
1997. The Company believes that the adoption of this Statement will not have a
material effect on its financial statements.
 
     In February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures
about Pensions and Other Postretirement Benefits," which standardizes the
disclosure requirements for pensions and other postretirement benefits. It does
not address measurement or recognition. This Statement is effective for fiscal
years beginning after December 15, 1997. The Company has not determined the
effect of adoption of this Statement on its financial statements.

LIQUIDITY AND CAPITAL RESOURCES
 
     At December 31, 1997, the Company had cash, cash equivalents and marketable
securities of $57.7 million, compared to $8.6 million at December 31, 1996. At
December 31, 1997, the Company's working capital was $161.9 million, compared to
$38.7 million at December 31, 1996. The increased working capital at December
31, 1997 was attributable to the net proceeds from the Offering not used to
repay indebtedness of the Company and the addition of Bowen and Cardwell's
working capital. At December 31, 1997, the Company had no long-term debt
outstanding.
 
     On March 31, 1997, the Company established the Term Loan and the Revolving
Credit Facility and issued the Senior Notes (collectively, the "Credit
Facilities") and borrowed approximately $98 million thereunder, primarily to
fund the Acquisitions. The Credit Facilities replaced a $15 million revolving
credit facility established in April 1996. On November 19, 1997, with net
proceeds from the Offering the Company fully redeemed the Senior Notes, repaid
in full the outstanding balance of the Term Loan and reduced the outstanding
balance of the Revolving Credit Facility to zero. See Item 5 "Market for
Registrant's Common Equity and Related Stockholder Matters." The extinguishment
of debt resulted in an extraordinary charge to income of $1.5 million consisting
of unamortized debt issuance costs of $2.3 million and related tax benefits of
$0.8 million. As a result of the repayment of all amounts outstanding under the
Revolving Credit Facility with a portion of the net proceeds of the Offering,
the Company may make additional borrowings under the Revolving Credit Facility
only up to a maximum aggregate amount of approximately $9.7 million less the
amount of letters of credit outstanding. At December 31, 1997, letters of credit
issued under the Revolving Credit Facility totaled $6.1 million (leaving
approximately $3.6 million available for borrowing under the Revolving Credit
Facility at such date).
 
     Management believes that current working capital in conjunction with
borrowings under the Revolving Credit Facility and credit facilities that may be
arranged in the future will be sufficient to meet the Company's short-term
(i.e., less than one year) and long-term liquidity needs. Though there can be no
assurance in this regard, management believes that any credit facilities
arranged in the near future would be on commercially reasonable terms.
 
  The Revolving Credit Facility
 
     The Revolving Credit Facility matures on March 31, 2000. The Company's
obligations under the Revolving Credit Facility are secured by first priority
security interests in substantially all of the assets of the Company, including
all personal property and material real property, the pledge by the Company of
all of the outstanding capital stock of Cardwell and the pledge by the Company
or Cardwell, as the case may be, of 66% of the outstanding capital stock of each
of the Company's direct and indirect foreign subsidiaries. Such obligations are
also guaranteed by Cardwell. The Revolving Credit Facility contains certain
representations and warranties, covenants and events of default customary for
facilities of this type.
 
YEAR 2000
 
     The Company has established a task force that is currently working to
ascertain and resolve the potential problems associated with the year 2000 and
the processing of date sensitive information by the Company's computer and other
systems. Based on preliminary information, the Company believes that it will be
able to implement successfully the systems and programming changes necessary to
address the year 2000 issues, and does not expect the cost of such changes to
have a material impact on the Company's financial position, results of
operations or cash flows in future periods.
 
ACQUISITIONS AND CAPITAL EXPENDITURES
 
     On March 31, 1997, the Company acquired substantially all of the assets and
business of Bowen from Air Liquide for a purchase price of approximately $75.1
million, and established its Bowen Tools Division. On April 17, 1997, the
Company acquired all of the outstanding capital stock of Cardwell, a privately
owned
 
                                       16
<PAGE>   17
 
company, as well as certain assets held by affiliates of Cardwell, for
approximately $12.0 million in cash and partial payment ($3.0 million) of a note
payable to one of Cardwell's bank lenders. In addition, the Company incurred
approximately $2.4 million ($1.8 million for Bowen and $0.6 million for
Cardwell) of transaction costs in connection with the Acquisitions. The
Acquisitions were financed with the proceeds of the Credit Facilities.
 
     The Acquisitions have been recorded using the purchase method of
accounting, and the results of operations of the acquired companies are included
in the statement of operations of the Company from the date of the respective
closings.
 
     In addition to funds used to finance the Acquisitions, capital expenditures
by the Company, Bowen and Cardwell during the year ended December 31, 1997
(including the period pre-Acquisition) totaled $10.6 million. During the twelve
month period ended December 31, 1996, capital expenditures by the Company, Bowen
and Cardwell were $8.2 million and included those relating to information
technology hardware and software, the re-opening of the Company's Beaumont,
Texas plant, which had been closed since 1985, and the purchase of machinery and
equipment at its Pampa, Texas facility.
 
     For the year ended December 31, 1997, the Company used cash flow in
operations of $20.8 million primarily to increase inventory levels to support
increases in sales. The Company believes that cash generated from operations and
amounts available under the Revolving Credit Facility will be sufficient to fund
operations, working capital needs, capital expenditure requirements and
financing obligations.
 
     For 1998, the Company has budgeted capital expenditures of $23.5 million,
including $11.2 million for the purchase of machinery and equipment and $12.3
million for equipment and tools manufactured at the Bowen Tools Division for use
in its rental operations. Capital expenditures are expected to be funded with
available cash, cash flow from operations and borrowings under the Revolving
Credit Facility.

The Board of Directors
IRI International Corporation:
 
     We have audited the consolidated financial statements of IRI International
Corporation and subsidiaries as listed in the accompanying index. 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 financial position of IRI
International Corporation as of December 31, 1997 and 1996 and the results of
their operations and their cash flows for the year ended December 31, 1997, the
nine months ended December 31, 1996, and the year ended March 31, 1996 in
conformity with generally accepted accounting principles.

                 IRI INTERNATIONAL CORPORATION AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) GENERAL
 
     IRI International Corporation (IRI or Company), a Delaware corporation, was
formed on July 30, 1985, through the combination of Ingersoll-Rand Oilfield
Products Company, a wholly-owned subsidiary of Ingersoll-Rand Company,
established August 1, 1980, and the Ideco Division of Dresser Industries, Inc.
On November 19, 1997, the Company sold 9.9 million shares of its common stock
through an initial public offering (IPO). Net proceeds totaled approximately
$163.9 million and were used partially to repay debt incurred in connection with
the acquisitions (see Notes 3 and 6). Remaining proceeds are invested primarily
in interest bearing deposit accounts and marketable equity securities.
 
     The Company manufactures and sells a full line of oil and gas mobile well
servicing and drilling rigs, deep oil and gas skid-mounted drilling rigs,
associated drilling equipment (Oilfield Equipment), and specialty steel products
(Specialty Steel). Raw materials are readily available and the Company is not
dependent upon a single or a few suppliers.
 
     On September 20, 1994, all of the outstanding common and preferred stock of
IRI was acquired by Energy Services International (ESI) for cash of $5 million.
The acquisition has been recorded using the purchase method of accounting and
the purchase price has been allocated to the assets acquired and liabilities
assumed based upon their estimated fair values at the date of the acquisition.
The excess of the fair value of net assets acquired over consideration was
applied against nonmonetary assets (property, plant and equipment) reducing the
balances at the acquisition date to zero. The remaining excess of the fair value
of net assets acquired over consideration paid of $26.8 million was recorded as
negative goodwill and is being amortized using the straight-line method over 5
years. Negative goodwill amortization of $5.4 million for the year ended
December 31, 1997, $4.0 million for the nine months ended December 31, 1996, and
$5.4 million for the year ended March 31, 1996, is included in cost of goods
sold in the accompanying statements of operations.
 
     IRI was subsequently merged into ESI in October 1997. ESI was the surviving
corporation and changed its name to IRI International Corporation.
 
     During 1996, the Company elected to change its fiscal year end from March
31 to December 31.
 
(2) SIGNIFICANT ACCOUNTING POLICIES
 
  (a) Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its subsidiaries. All significant intercompany balances and transactions
have been eliminated in consolidation.
 
  (b) Statements of Cash Flows
 
     Cash equivalents of $49,500,000 and $8,600,000 at December 31, 1997 and
1996, respectively, consisted of interest-bearing cash deposits. For purposes of
the statement of cash flows, the Company considers all cash and short-term
highly liquid debt instruments with original maturities of three months or less
to be cash equivalents.
 
     During the year ended December 31, 1997 and the nine months ended December
31, 1996, the Company entered into capital lease obligations of $309,000 and
$810,000, respectively.
 
  (c) Marketable Securities
 
     Marketable securities at December 31, 1997 consist of corporate equity
securities. The Company classifies its equity securities as trading securities.
Trading securities are bought and held principally for the
 
                                       24
<PAGE>   25
                 IRI INTERNATIONAL CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
purpose of selling them in the near term and are recorded at fair value.
Unrealized holding gains of approximately $770,000 are included in other income
for the year ended December 31, 1997.
 
  (d) Inventories
 
     Inventories are stated at the lower of cost or market. Cost is determined
using standard costs which approximate actual cost on a first-in, first-out
basis for all inventories excluding oilfield equipment work-in-process, parts
and raw materials, which are recorded at actual cost on a first-in, first-out
basis. Work-in-process inventories related to fixed price contracts are stated
at the accumulated cost of material, labor and manufacturing overhead, less the
estimated costs of units delivered.
 
  (e) Property, Plant and Equipment
 
     Depreciation of property, plant and equipment is provided over the
estimated service lives of assets principally using the straight-line method.
Maintenance, repairs and minor replacements are charged to operations as
incurred; major repairs, replacements or improvements are capitalized.
 
     Long-lived assets and certain identifiable intangible assets are reviewed
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Recoverability of assets to
be held and used is measured by a comparison of the carrying among of an asset
to future net cash flows expected to be generated by the asset. If such assets
are considered to be impaired, the impairment to be recognized is measured by
the amount by which the carrying amount exceeds the fair value of the assets.
Assets to be disposed of are reported at the lower of the carrying amount or
fair value less costs to sell.
 
  (f) Income Taxes
 
     Income taxes are accounted for under the asset and liability method.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.
 
  (g) Revenue Recognition
 
     The Company recognizes construction contract revenues for rigs and
significant components using the percentage-of-completion method. Under the
percentage-of-completion method, revenues and profits are recognized based on
the percentage of completion throughout the performance period of the contract.
The percentage-of-completion is calculated based on the ratio of contract costs
incurred to date to total estimated contract costs after providing for all known
or anticipated costs. Costs include material, direct labor and engineering and
manufacturing overhead. Selling expenses and general and administrative expenses
are charged to operations as incurred. The effect of changes in estimates of
contract costs is recorded currently. If estimates of costs to complete
contracts indicate a loss, provision is made currently for the total loss
anticipated. All remaining revenue is generally recorded when the equipment is
shipped.
 
     Costs and estimated earnings in excess of billing on uncompleted contracts
represent revenues earned under the percentage-of-completion method but not yet
billable under the terms of the contract. Amounts are billable under contracts
generally upon shipment of the products or completion of the contracts. Included
in revenues and cost of goods sold for the year ended December 31, 1997 is
$34,842,000 and $25,989,000, respectively, related to uncompleted contracts
($8,853,000, net) at December 31, 1997. Included in revenues
 
                                       25
<PAGE>   26
                 IRI INTERNATIONAL CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
and cost of goods sold for the nine months ended December 31, 1996 is $764,000
and $741,000, respectively, related to uncompleted contracts ($23,000 net) at
December 31, 1996.
 
  (h) Earnings per Common Share
 
     The Company adopted Statement of Financial Accounting Standard ("SFAS") No.
128, "Earnings Per Share" during the fourth quarter of 1997. Under SFAS No. 128,
basic earnings per share (EPS) is computed by dividing income available to
common shareholders by the weighted average number of common shares outstanding
for the period. Diluted EPS reflects the potential dilution that could occur if
securities or other contracts to issue common stock were exercised or converted
into common stock or resulted in the issuance of common stock that then shared
in the earnings of the entity. For the years and quarters presented herein,
basic and diluted earnings per share are the same. Options outstanding at
December 31, 1997 are anti-dilutive as the exercise price is greater than the
market price at December 31, 1997.
 
  (i) Financial Instruments and Credit Risk Concentrations
 
     The Company invests its excess cash in financial instruments, primarily
overnight investments and money market mutual funds. These financial instruments
could potentially subject the Company to concentrations of credit risk; however,
the Company's management considers the financial stability and creditworthiness
of a financial institution before investing the Company's funds. The carrying
amounts of the financial instruments in the accompanying financial statements
(cash, accounts receivable and payables) approximate fair value because of the
short maturities of these instruments. The capital lease obligation bears
interest at rates that approximate market rates and, thus the carrying amount
approximates estimated fair value.
 
     A substantial portion of the Company's customers are engaged in the energy
industry. This concentration of customers may impact the Company's overall
exposure to credit risk, either positively or negatively, in that customers may
similarly affected by changes in economic and industry conditions. The Company
performs ongoing credit evaluations of its customers. The Company maintains
reserves for potential credit losses, and actual losses have historically been
within the Company's expectations. Foreign sales also present various risks,
including risks of war, civil disturbances and governmental activities that may
limit or disrupt markets, restrict the movement of funds or result in the
deprivation of contract rights or the taking of property without fair
consideration. Most of the Company's foreign sales, however, are to large
international companies or are secured by letters of credit or similar
arrangements.
 
  (j) 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.
 
(3) ACQUISITIONS
 
     On March 31, 1997, the Company acquired certain assets and assumed
liabilities of Bowen Tools, Inc. ("Bowen"), a wholly owned subsidiary of the
French chemical concern L'Air Liquide, for a total consideration of $75.1
million. On April 17, 1997, the Company also acquired the stock of Cardwell
International Ltd. ("Cardwell"), a privately owned company, as well as certain
assets held by affiliates of Cardwell for approximately $12 million in cash at
closing and partial payment ($3 million) of a note payable to bank. In addition
the Company incurred approximately $3.2 million ($2.6 million for Bowen and $.6
million for Cardwell) of transaction costs in connection with the acquisitions.
The acquisitions were financed through a $65 million senior secured term loan
facility and $31 million of interim senior subordinated increasing rate
                                       26

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
notes. The notes outstanding under the term loan facility and the senior
subordinated increasing rate notes were repaid with the proceeds from the
Company's equity offering (see note 1).
 
     Bowen, headquartered in Houston, Texas, designs, manufactures and markets
fishing tools and drilling, power and wireline/pressure control equipment used
in the drilling and completion of oil and gas wells. Cardwell, headquartered in
El Dorado, Kansas, manufactures and sells drilling rigs, related oilfield
equipment and supplies predominantly to foreign countries.
 
     The acquisitions have been recorded using the purchase method of accounting
and results of operations of the acquired companies have been included in the
consolidated statement of operations of IRI from the dates of the respective
acquisitions. The cost of the Bowen and Cardwell acquisitions have been
allocated to the assets acquired and liabilities assumed based on their
respective fair values as follows (in thousands):

     The excess of consideration given over the fair value of the net tangible
assets acquired of $6,096,000 is being amortized over five years using the
straight-line method.
 
     The following sets forth selected consolidated financial information for
the Company on a pro forma basis for the years ended December 31, 1997 and 1996,
assuming the Bowen and Cardwell acquisitions had occurred on January 1, 1996 (in

     Machinery and equipment includes capitalized lease assets of $1,119,000,

(6) NOTES PAYABLE
 
     In connection with the acquisitions described in note 3, the Company
entered into a $65 million senior secured term loan facility due in quarterly
installments beginning June 30, 1997 through March 31, 2002 and a $31 million
interim senior subordinated increasing rate note due March 31, 1998. Amounts
outstanding under these notes were repaid with proceeds from the Company's
initial public offering in November 1997. The extinguishment of this debt
resulted in an extraordinary charge of $1,512,000 consisting of unamortized
financing costs of $2,353,000 and income tax benefit of $841,000.
 
     The Company has a $9.7 million revolving credit facility which matures on
March 31, 2000. Amounts outstanding under the revolving credit facility are
secured by substantially all of the assets of the Company and accrue interest at
a rate per annum equal to the one, two, three or six month LIBOR plus 2 3/4%.
Amounts available under the revolving credit facility ($3,605,000 at December
31, 1997) are limited to the excess of the revolving credit commitment over then
outstanding letter of credit obligations. The revolving credit facility
agreement contains provisions, among others, that restrict incurrence of
indebtedness, guarantees, acquisitions, and distributions to shareholders, and
require the Company to meet specified financial maintenance tests.
 
     During the year ended March 31, 1996, the Company obtained a $15 million
revolving credit facility with a bank available through February 1998.
Borrowings under the credit facility bear interest at the prime rate (8.25% at
December 31, 1996) plus an applicable margin. As of December 31, 1996, there was
$21,000 outstanding on the line of credit. The line of credit was canceled on
March 31, 1997 in connection with the acquisitions and related financing
described in note 3.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     At December 31, 1996 the Company had a $3 million unsecured demand note
payable to Towers Financial Services bearing interest at 14% per annum. The note
and accrued interest were paid in January 1997.
 
(7) SHAREHOLDERS' EQUITY
 
     On October 14, 1997, the Company merged into ESI. ESI was the surviving
corporation and changed its name to IRI International Corporation. At the time
of the merger, ESI had 100 common shares issued and outstanding, no liabilities
and its sole asset was its investment in the Company. As a result of the merger,
each share of common stock of ESI was converted into 300,000 shares of the
surviving corporation, each treasury share of common stock was canceled and each
share of preferred stock of the Company, including accrued and unpaid dividends
thereon, was canceled. The authorized capital stock of the Company was increased
to 100,000,000 common shares and 25,000,000 preferred shares. The consolidated
financial statements, including all references to the number of shares of common
and preferred stock and all per share information, have been adjusted to reflect
the merger and the other changes in capital structure on a retroactive basis.
 
(8) STOCK OPTIONS
 
     In anticipation of the initial public stock offering, the Company granted
its Directors and certain of its officers and employees an aggregate of
1,933,000 options to purchase shares of common stock. Directors not employed by
the Company received options to purchase an aggregate of 160,000 shares of
common stock having an exercise price that will be equal to the initial public
offering price. The options granted to Directors not employed by the Company
vest as to one-half of the option shares on the effective date of the Offering
and as to a further one-quarter of the option shares on the first and second
anniversaries of the effective date of the Offering. Certain executive officers
and employees received options to purchase an aggregate of 1,773,000 shares of
common stock having an exercise price equal to the greater of the initial public
offering price and the fair market value of the option shares on the date such
options vest. The options granted to certain executive officers and employees
generally vest as to one-third of the option shares upon the effective date of
the Offering and as to a further one-third of the option shares on the first and
second anniversaries of the effective date of the Offering.
 
     The Company applies APB Opinion 25 in accounting for its plan. Accordingly,
no compensation cost has been recognized for stock options granted to employees.
Compensation expense is recorded for options granted to non-employee directors
based on the estimated fair value of the options on the date of grant. The
compensation cost that has been charged against income for non-employee director
options granted was $499,000 for the year ended December 31, 1997. Had
compensation cost for the Company's stock option plans been determined based on
the fair value at the grant dates for awards to employees under the plan
consistent with the method of SFAS No. 123, the Company's net income and
earnings per share for the year ended December 31, 1997 would have been reduced
to the pro forma amounts indicated below (in thousands except per share data):

     Because of the uncertainty of generating future taxable income, the Company
has provided a valuation allowance for deferred tax assets of $4,378,000 and
$5,669,000 at December 31, 1997 and December 31, 1996, respectively. The
valuation allowance decreased $1,291,000 during the year ended December 31, 1997
and $1,504,000 during the nine months ended December 31, 1996. In assessing the
realizability of deferred tax assets, management considers whether it is more
likely than not that some portion of all of the deferred tax assets will not be
realized. The ultimate realization of deferred tax assets is dependent upon the
generation of future taxable income during the periods in which those temporary
differences become deductible. Manage-

ment considers the scheduled reversal of deferred tax liabilities, projected
future taxable income, and tax planning strategies in making this assessment.
 
     Under the Internal Revenue Code of 1986, in general, a change of more than
50% in the composition of a company's equity owners during any three years
results in a limitation on such company's ability to utilize its loss
carryforwards in subsequent years. The Company has undergone such an ownership
change as a result of the sale described in note 1; accordingly, the amount of
the Company's preacquisition net operating loss carryforwards that may be
utilized per year is limited to approximately $300,000 (aggregate $3,600,000
available at December 31, 1997) expiring from 2003 through 2009. To the extent
such carryforwards are not utilized in a year, they may be utilized in
subsequent years.

(11) PENSION PLAN
 
     The Company has a noncontributory defined benefit pension plan, which
covers substantially all employees. Employees with 10 or more years of service
are entitled to pension benefits beginning at normal retirement age (65) based
on years of service and the employees' compensation for the 60 consecutive month
period in which his compensation is the highest. The plan incorporates
provisions for early retirement, the privilege to elect a life annuity,
surviving spouse benefits, and disability benefits.
 
     Employees of the Company who were employees of Ingersoll-Rand Oilfield
Products Company or the Ideco Division of Dresser Industries, Inc., immediately
prior to becoming employees of IRI, are entitled to uninterrupted service tenure
for purposes of retirement benefit calculations. Benefits payable under the IRI
retirement plan are offset by benefits payable under the retirement plans of
Dresser and Ingersoll-Rand Oilfield Products Company.
 
     The Company uses the accrued benefit cost method to compute the annual
contributions to the plan, with minimum and maximum contributions determined on
a cumulative basis and the Company having the flexibility to choose which
contribution to make and which can vary from one period to the next.
 
     The accrued benefit cost includes a normal cost which is computed as the
present value of the pro rata portion for the benefit accrual during the year
being valued and a past service cost which is the present value of

date. The unfunded past-service cost may be liquidated over a period of between
10 and 30 years.

     The Plan assets consist primarily of interest bearing demand deposit
accounts at December 31, 1997 and time-share real estate notes and fixed income
time deposits at December 31, 1996.
 
     The provisions of SFAS No. 87, "Employers' Accounting for Pensions",
require the recognition of an additional minimum liability for each defined
benefit plan for which the accumulated benefit obligation exceeds plan assets.
This amount has been recorded as a long-term liability with an offsetting
intangible asset. Because the asset recognized may not exceed the amount of
unrecognized prior service cost and transition obligation on an individual plan
basis, the balance of $1,457,000 is reported as a separate reduction of
shareholders' equity at December 31, 1997.

     As of September 1, 1995, the pension plan was frozen insofar as future
accrual of pension benefits. Because the plan amendment to freeze the plan was
planned in conjunction with the ESI acquisition discussed in note 1, the
resulting curtailment gain was taken into consideration in remeasuring the
Company's projected benefit obligation and the date of the acquisition.
 
     The development of the actuarial present value of the projected benefit
obligation at December 31, 1997 and December 31, 1996 was based upon a weighted
average discount rate of 7.30% and 7.90%, respectively, and an expected
long-term rate of return on assets of 8.0%.

     The Pension Guaranty Corporation provides protection to plan participants
by assuring employees that the fixed commitment of the Company for funding
vested accrued benefits of the plan will be paid up to specified maximum amounts
should the Company be unable to fund the fixed commitment.
 
     The plan is administered by the Pension Committee which is appointed by
IRI's Board of Directors.
 
     The Company also has a defined contribution plan which covers most of its
employees. The plan provides mandatory contributions from the Company to
eligible employees in the plan equal to 7 1/2% of their annual pay. Plan
participants become fully vested in contributions made by the Company following
three years of credited service. The Company recognized expense associated with
the plan of approximately $1,076,000, $665,000, and $418,000 for the year ended
December 31, 1997, the nine-months ended December 31, 1996 and the year ended
March 31, 1996, respectively.
 
(12) POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
 
     In addition to the Company's defined benefit pension plan, the Company
sponsors a defined benefit health care plan that provides postretirement medical
benefits to retirees or full-time employees who retire after attaining age 55
with at least 10 years of service as of September 1, 1996. Current retirees
receive benefits for life while full time employees (future retirees) only
receive benefits until age 65. The plan is a contributory, with retirees
contributing 20% of the health care costs. The Company's contribution is capped
at a 5% annual increase in health care costs, with the remaining increases to be
paid by the employee. The Company's policy is to fund the cost of medical
benefits in amounts determined at the discretion of management.

     On August 11, 1995, the plan was amended to terminate all employees from
the plan except those eligible to retire on June 30, 1995 and all current
retirees. In addition under the amended plan, active employees eligible to
retire will, after the age of 65, receive through the retirement plan, 80% of
the cost of medical insurance with a 5% cap over a base year premium of calendar
1996. Because it was expected that the plan would be terminated in conjunction
with the ESI acquisition discussed in note 1, the effects were considered in
measuring the Company's accumulated post retirement benefit obligation as of the
acquisition date.

     The discount rates used in determining the accumulated postretirement
benefit obligation were 7.30% and 7.75% at December 31, 1997 and December 31,
1996, respectively. The assumed health care cost trend rate was 10% in 1995
graded down to 5% after 12 years. Because health care cost increases over 5%
annually are borne by the employees, the amounts reported are not affected by
increases in the assumed health care cost trend rate.

(14) COMMITMENTS AND CONTINGENCIES
 
     The Company has contract commitments aggregating $69.4 million at December
31, 1997 for the manufacture and delivery of drilling and workover rigs during
fiscal year 1998.
 
     At December 31, 1997, the Company was contingently liable for approximately
$6.6 million in letters of credit which guarantee the Company's performance for
payment to third parties in accordance with specified contractual terms and
conditions. These letters of credit are primarily secured by the Company's cash,
accounts receivable and inventory. Management does not expect any material
losses to result from these off-balance-sheet instruments as it anticipates full
performance on the related contracts.
 
     Various federal, state and local laws, regulations and ordinances govern
the removal, encapsulation or disturbance of asbestos containing materials
("ACMs"). Such laws and regulations may impose liability for the release of ACMs
and may provide for third parties to seek recovery from owners or operators of
facilities at which ACMs were or are located for personal injury associated with
exposure to ACMs. The Company is aware of the presence of ACMs at its
facilities, but it believes that such materials are in acceptable condition at
this time. The Company believes that any future costs related to remediation of
ACMs at these sites will not be material, either on an annual basis or in the
aggregate, although there can be no assurance with respect thereto.
 
     The Company has sought to reduce the impact of costs arising from or
related to actual or potential environmental conditions at the Bowen Tools
Division facilities caused or created by Bowen or its predecessors in title
through the Company's contractual arrangements with Air Liquide America
Corporation ("Air Liquide"). Pursuant to such arrangements, Air Liquide and
Bowen agreed to indemnify the Company for such costs. Air Liquide provided the
Company with certain environmental assessments with respect to most of the Bowen
properties conveyed to the Company. In some cases, these initial assessments
recommended the performance of further investigation to evaluate the need for
and to determine the extent of the removal or remediation of hazardous
substances required to address historical operations of Bowen. Air Liquide is
conducting a further environmental review of the Bowen Tools Division facilities
to determine the potential scope of remediation to be conducted at such
facilities by Air Liquide or Bowen. There can be no assurance

<PAGE>   37
                 IRI INTERNATIONAL CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
that Air Liquide or Bowen will meet its obligations under the indemnification
arrangements or that there will not be future contamination for which the
Company might be fully liable and that may require the Company to incur
significant costs that could have a material adverse effect on the Company's
financial conditions and results of operations.
 
     Although the Company believes that it is in substantial compliance with
existing laws and regulations, there can be no assurance that substantial costs
for compliance will not be incurred in the future. Moreover, it is possible that
other developments, such as stricter environmental laws, regulations and
enforcement policies thereunder, could result in additional, presently
unquantifiable, costs or liabilities to the Company.
 
     The Company is involved in various other claims and legal actions arising
in the ordinary course of business. In the opinion of management, the ultimate
disposition of these matters will not have a material adverse effect on the
Company's consolidated financial position, results of operations or liquidity.
 
(15) SUBSEQUENT EVENT
 
     On March 8, 1998, the Board of Directors of the Company and of Hitec ASA, a
Norwegian Corporation ("Hitec") approved a transaction (the "Hitec Transaction")
whereby the businesses of the Company and Hitec will be combined and the
resulting company will be named "IRI Hitec, Inc." Pursuant to the Hitec
Transaction, Hitec shareholders will receive 0.5748 of a newly issued share of
IRI Common Stock for each common share of Hitec. The Hitec Transaction is
subject to, among other things, the approval of the Company's stockholders and
the tender of at least 90% of Hitec's outstanding common shares.
 
     Hitec is engaged primarily in the design and engineering of advanced
technology for the offshore oil and gas industry.
