Item 1. Business

GENERAL

National Oilwell designs, manufactures and sells comprehensive systems, components, and equipment used in oil and gas drilling and production, as well as distributes products and provides services to the exploration and production segment of the oil and gas industry.

Our Products and Technology segment designs and manufactures complete land drilling and workover rigs, as well as drilling related systems for offshore rigs. Technology has increased the desirability of one vendor assuming responsibility for the entire suite of components used in the drilling process, as mechanical and hydraulic components are replaced by or augmented with integrated computerized systems. In addition to traditional components such as drawworks (the hoisting winch used to raise and lower drill pipe), mud pumps (used to circulate drilling fluids), top drives (used to turn drill pipe), derricks, cranes, jacking and mooring systems (used to raise and lower offshore jackup drilling rigs and anchor floating drilling rigs), and other structural components, we provide automated pipehandling, control and electrical power systems. We have also developed new technology for drawworks and mud pumps applicable to the highly demanding offshore markets.

Non-capital revenue sources within our Products and Technology segment include drilling motors and specialized downhole tools that are sold or rented, spare parts and service on the large installed base of our equipment, expendable parts for mud pumps and other equipment, and smaller downhole, progressive cavity and transfer pumps.

Our Distribution Services segment provides maintenance, repair and operating supplies and spare parts to drill site and production locations throughout North America and to offshore contractors worldwide. Increasingly, this business also is expanding to locations outside North America, including the Middle East, Southeast Asia, and South America. Using our information technology platforms and processes, we can provide complete procurement, inventory management, and logistics services to our customers.

BUSINESS STRATEGY

National Oilwell’s business strategy is to enhance its market positions and operating performance in the upstream oil and gas business by:

Leveraging our Capital Equipment Installed Base

We believe our market position and comprehensive product offering present substantial opportunities to capture a significant portion of expenditures for the construction of new drilling rigs and equipment as well as the upgrade and refurbishment of existing drilling rigs and equipment. Over the next few years, the advanced age of the existing fleet of drilling rigs, coupled with drilling activity involving greater depths and extended reach, is expected to generate demand for new equipment. National Oilwell’s automation and control systems offer the potential to improve the performance of new and existing drilling rigs. The large installed base of our equipment also provides recurring demand for spare parts and expendable products necessary for proper and efficient operation.

1

Expanding our Non-Capital Products Business

Our non-capital equipment revenues continue to represent approximately half of our products and technology business. We rent and sell high-performance drilling motors and downhole tools and manufacture certain expendable products and spare parts needed in the drilling and production process. We believe additional expansion in the non-capital upstream oil and gas industry would be beneficial to our business and our customers.

Furthering our Information Technology and Process Improvement Strategy

National Oilwell has developed an integrated information technology and process improvement strategy to enhance procurement, inventory management and logistics activities. As a result of the need to improve industry efficiency, oil and gas companies and drilling contractors are frequently seeking alliances with suppliers, manufacturers and service providers to achieve cost and capital improvements. We believe we are well positioned to provide these services as a result of our:

In addition, the integration of our distribution expertise, extensive network and growing base of customer alliances provides an increased opportunity for cost-effective marketing of our manufactured parts and equipment.

Continuing our Acquisitions Strategy

We believe the oilfield service and equipment industry will continue to experience consolidation as businesses seek to align themselves with other market participants in order to gain access to broader markets and integrated product offerings. Since 1997, we have completed forty-two acquisitions and plan to continue to participate in this consolidation trend. The aggregate effect of these acquisitions has positively impacted our ability to provide complete drilling equipment systems to our customers.

OPERATIONS

Products and Technology

National Oilwell designs, manufactures and sells drilling systems and components for both land and offshore drilling rigs as well as complete land drilling and well servicing rigs. Mechanical components include drawworks, mud pumps, top drives, solids control equipment (used to remove particulates from drilling fluids), traveling equipment (hooks and blocks used to hoist and lower drill pipe) and rotary tables (used to rotate drill pipe). These components are essential to pump fluids and hoist, support and rotate the drill string. Many of these components are designed specifically for applications in offshore, extended reach and deep land drilling operations. This equipment is installed on new rigs and often replaced during the upgrade and refurbishment of existing rigs.

We design and manufacture masts, derricks and substructures for use on land rigs and on fixed and mobile offshore platforms suitable for drilling applications to depths of up to 30,000 feet or more. Other products include cranes,

2

jacking and mooring systems, reciprocating and centrifugal pumps and fluid end expendables for all major manufacturers’ pumps. Our business includes the sale of replacement parts for our own manufactured machinery and equipment.

We also design and manufacture electrical systems and control and data acquisition systems for drilling related operations and automated and remotely controlled machinery for drilling rigs. Our control systems can control and monitor many simultaneous operations on a drilling rig and often form the basis for our state-of-the-art driller’s cabin. Our automated pipe handling system provides an efficient and cost effective method of joining lengths of drill pipe or casing, as does our iron roughneck. These and similar technologically advanced products can greatly improve the safety on rigs, often by reducing the number of persons working on the drilling floor.

While offering a complete line of conventional rigs, National Oilwell has extensive experience in providing rig designs to satisfy requirements for harsh or specialized environments. Such products include drilling and well servicing rigs designed for the Arctic, highly mobile drilling and well servicing rigs for jungle and desert use, modular well servicing rigs for offshore platforms and modular drilling facilities for North Sea platforms. We also design and produce fully integrated drilling equipment packages for offshore rigs.

National Oilwell designs and manufactures drilling motors, drilling jars and specialized drilling tools for rent and sale. We also design and manufacture a complete line of fishing tools, used to remove objects stuck in the wellbore, and progressive cavity pumps.

Distribution Services

National Oilwell provides distribution services through its network of 147 distribution service centers. National Oilwell’s distribution service centers are located throughout the oil and gas producing regions of North America, with 90 in the United States, 41 in Canada, and the remainder in various international locations. These distribution service centers stock and sell a variety of expendable items for oilfield applications and spare parts for our proprietary equipment. As oil and gas companies and drilling contractors have refocused on their core competencies and emphasized efficiency initiatives to reduce costs and capital requirements, our distribution services have expanded to offer outsourcing and alliance arrangements that include comprehensive procurement, inventory management and logistics support. In addition, we believe we have a competitive advantage in the distribution services business by distributing products manufactured by us and from the association of this business with our Products and Technology segment.

The supplies and equipment stocked by our distribution service centers vary by location. Each distribution point generally offers a large line of oilfield products including valves, fittings, flanges, spare parts for oilfield equipment and miscellaneous expendable items.

Most drilling contractors and oil and gas companies typically buy supplies and equipment pursuant to non-exclusive contracts, which normally specify a discount from list price for each product or product category. Our goal is to create strategic alliances with our customers whereby we become the customer’s primary supplier of those items. In certain cases, we assume responsibility for procurement, inventory management and product delivery for the customer, occasionally by working directly out of the customer’s facilities.

We believe e-commerce brings a significant advantage to larger companies that are technologically proficient. Our e-commerce system can interface directly with customers’ systems to maximize efficiencies for us and for our customers. We believe we have an advantage in this effort due to our investment in technology, geographic size, knowledge of the industry and customers, existing relationships with vendors and existing means of product delivery.

Marketing

Substantially all of our capital equipment and spare parts sales, and a large portion of our smaller pumps and parts sales, are made through our direct sales force and distribution service centers. Sales to foreign state-owned oil companies are typically made in conjunction with agent or representative arrangements. Our downhole products are generally rented and sold worldwide through our own sales force and through commissioned representatives. Distribution sales are made through our network of distribution service centers. Customers for our products and services include drilling and other service contractors, exploration and production companies, supply companies and nationally owned or controlled drilling and production companies.

Competition

The oilfield services and equipment industry is highly competitive and our revenues and earnings can be affected by price changes, introduction of new technologies and products and improved availability and delivery. Our Products and Technology business segment competes with several companies in North America that have drilling products that compete directly with certain of our products. Our Distribution Services business segment competes with various smaller regional competitors who may have strong direct ties with smaller or decentralized drilling and production companies and other multinational distribution companies on the basis of service and price. None of these competing companies dominate in any of the business segments or geographic areas in which we operate.

Manufacturing and Backlog

National Oilwell has manufacturing facilities located in the United States, Canada, England, France, Norway and China. The manufacture of parts or purchase of components is sometimes outsourced to qualified subcontractors. The manufacturing operations require a variety of components, parts and raw materials which we purchase from multiple commercial sources. We have not experienced and do not expect any significant delays in obtaining deliveries of materials.

Sales of products are made on the basis of written orders and oral commitments. Our backlog for equipment at recent year-ends has been:

Distribution Suppliers

National Oilwell obtains products sold by its Distribution Services business from a number of suppliers, including our own Products and Technology segment. No single supplier of products is significant to our operations. We have not experienced and do not expect a shortage of products that we sell.

Engineering

National Oilwell maintains a staff of engineers and technicians to:

Our product engineering efforts focus on developing technology to improve the economics and safety of drilling and production processes, and to emphasize technology and complete drilling solutions.

4

Patents and Trademarks

National Oilwell owns or has a license to use a number of patents covering a variety of products. Although in the aggregate these patents are of importance, we do not consider any single patent to be of a critical or essential nature. In general, our business has historically relied upon technological capabilities, quality products and application of expertise rather than patented technology.

Employees

As of December 31, 2004, we had a total of 7,550 employees, 4,630 of whom were salaried and 2,920 of whom were paid on an hourly basis. Of this workforce, 1,575 employees are employed in Canada, 790 in Norway, 450 in the United Kingdom and 800 in other locations outside the United States. In addition, we also had approximately 1,215 employees in our joint venture operation in Lanzhou, China.

RISK FACTORS

You should carefully consider the risks described below, in addition to other information contained or incorporated by reference herein. Realization of any of the following risks could have a material adverse effect on our business, financial condition, cash flows and results of operations.

Risks Related to the Merger and the Related Transactions

On August 11, 2004, we agreed to combine our businesses with Varco International, Inc. by merging Varco with and into National Oilwell, with National Oilwell continuing as the surviving corporation. Consummation of the merger requires approval by the stockholders of both companies and also approval from various regulatory agencies. We anticipate completion of the merger during March 2005.

We may not be able to successfully integrate our operations with Varco and realize the anticipated benefits of the merger.

Achieving the benefits we expect from the merger will depend in large part on integrating our technology, operations and personnel in a timely and efficient manner to minimize the impact on customers, employees and management. Integration of the two previously independent companies will be a complex, time consuming and costly process. Failure to timely and successfully integrate these companies may have a material adverse effect on the combined company’s business, financial condition and results of operations. The difficulties of combining the companies will present challenges to the combined company’s management, including:

5

The combined company will also be exposed to other risks that are commonly associated with transactions similar to the merger, such as unanticipated liabilities and costs, some of which may be material, and diversion of management’s attention. As a result, we cannot assure you that we will realize any of the anticipated benefits of the merger, including anticipated cost savings, and failure to do so could adversely affect the business of the combined company after the merger.

The costs of the merger could adversely affect combined financial results.

We expect the total merger-related costs, exclusive of employee benefit costs, to be approximately $30.0 million, consisting primarily of financial advisory, legal and accounting fees, financial printing costs and other related charges. The amount of these expenses is a preliminary estimate and is subject to change. In addition, the combined company will incur certain integration costs, including, but not limited to, costs associated with consolidating administrative and operational functions and the closure of certain facilities. If the benefits of the merger do not exceed the costs associated with the merger, including any dilution to the stockholders of both companies resulting from the issuance of shares in connection with the merger, the combined company’s financial results, including earnings per share, could be adversely affected.

The exchange ratio for National Oilwell common stock to be received in the merger is fixed and will not be adjusted in the event of any change in stock price.

Upon completion of the merger, each share of Varco common stock will be exchanged for 0.8363 of a share of National Oilwell common stock. This conversion number is fixed and will not be adjusted as a result of any change in the price of National Oilwell common stock or Varco common stock. In addition, neither National Oilwell nor Varco may terminate the merger agreement solely because of changes in the market price of either company’s common stock.

National Oilwell stockholders will be diluted by the merger.

The merger will dilute the ownership position of the present stockholders of National Oilwell. Based on the number of shares of Varco common stock outstanding as of January 27, 2005, National Oilwell will issue to Varco stockholders approximately 82,099,809 shares of National Oilwell common stock in the merger. As a result, Varco stockholders and National Oilwell stockholders will hold approximately 49% and 51%, respectively, of the combined company’s common stock outstanding after the completion of the merger, based on the common stock of National Oilwell and Varco outstanding as of January 27, 2005.

Failure to complete the merger or delays in completing the merger could negatively impact National Oilwell’s stock price and future business and operations.

If the merger is not completed for any reason, National Oilwell and Varco may be subject to a number of material risks, including the following:

6

In addition, in response to the announcement of the merger, customers may delay or defer purchasing decisions. Any delay or deferral of purchasing decisions by customers could negatively affect the business and results of operations of National Oilwell, regardless of whether the merger is ultimately completed. Similarly, current and prospective employees of National Oilwell may experience uncertainty about their future roles with the companies until after the merger is completed or if the merger is not completed. This may adversely affect the ability of National Oilwell to attract and retain key management, marketing and technical personnel.

Furthermore, while the merger agreement is in effect, subject to certain limited exceptions, National Oilwell is prohibited from soliciting, initiating or encouraging or entering into any extraordinary transactions, such as a merger, sale of assets or other business combination, with any third party, subject to exceptions set forth in the merger agreement. As a result of these limitations, National Oilwell may lose opportunities to enter into a more favorable transaction. Finally, if the merger is terminated and the National Oilwell board of directors determines to seek another merger or business combination, we cannot assure you that it will be able to find a transaction providing as much stockholder value as this merger.

National Oilwell and Varco could be required to divest, hold separate or license assets to complete the merger.

We cannot complete the merger until the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 or any other applicable waiting period has expired or is otherwise terminated. On September 10, 2004, National Oilwell and Varco made the required filings relating to the merger with the FTC and the DOJ. On October 12, 2004, National Oilwell and Varco received a request for additional information and documentary material from the DOJ, which they furnished. National Oilwell and Varco have also made required filings relating to the merger with various government authorities in a number of foreign jurisdictions in which one or both companies have sufficient market presence to require filings. We continue to work with these various governmental agencies to obtain regulatory clearance to complete the merger. As a prerequisite to obtaining the expiration or termination of this waiting period, or to avoid an injunction by the Department of Justice or another governmental entity, whether foreign or domestic, National Oilwell, Varco or both companies may be required to divest, hold separate or license certain assets. Although each of National Oilwell and Varco have agreed to use their reasonable best efforts to obtain the expiration or termination of this waiting period and to obtain any other governmental clearance or approvals under federal, state or foreign antitrust laws, neither National Oilwell nor Varco is required to divest, hold separate or license any of their respective businesses, product lines or assets, take or agree to take any other action or agree to any limitation, that would reasonably be expected to have a material adverse effect on the financial condition, results of operations or prospects of National Oilwell or Varco.

Divestitures or licensing of assets can be time consuming and may delay or prevent completion of the proposed merger. Because there may be a limited number of potential buyers or licensees for the assets subject to divestiture or license and because potential buyers will likely be aware of the circumstances of the sale or license, these assets could be sold or licensed at prices or rates lower than their fair market values or the prices National Oilwell or Varco paid for these assets. Asset divestitures or licenses of National Oilwell’s or Varco’s assets could also significantly reduce the value of the combined company, eliminate potential cost savings opportunities or lessen the anticipated benefits of the merger.

7

Some of the directors and executive officers of National Oilwell have interests that differ in several respects from their respective stockholders.

In considering the recommendation of the board of directors of National Oilwell to adopt the merger agreement, the stockholders of National Oilwell should consider that some of their respective directors and executive officers have interests that differ from, or are in addition to, their interests as stockholders of National Oilwell generally. These interests include the expectation of being elected a director or appointed an officer of the combined company, the benefits that directors and officers may receive in connection with any acceleration of the vesting of their outstanding equity awards as a result of the merger or their terminations of service, and the potential payments that certain officers of National Oilwell may receive as a result of the merger. As a result, these officers and directors may be more likely to vote to adopt the merger agreement than if they did not hold these interests. You should consider whether these interests may have influenced these officers and directors to support or recommend the merger.

If National Oilwell or Varco fails to obtain all required consents and waivers, third parties may terminate or alter existing contracts.

Certain agreements with suppliers, customers, licensors or other business partners may require National Oilwell or Varco to obtain the approval or waiver of these other parties in connection with the merger. National Oilwell and Varco have agreed to use reasonable efforts to secure the necessary approvals and waivers. However, we cannot assure you that National Oilwell and/or Varco will be able to obtain all of the necessary approvals and waivers, and failure to do so could have a material adverse effect on the business of the combined company after the merger.

Risks Related to National Oilwell

National Oilwell is dependent upon the oil and gas industry, which may be volatile.

The oil and gas industry historically has experienced significant volatility. Demand for our services and products depends primarily upon the number of oil rigs in operation, the number of oil and gas wells being drilled, the depth and drilling conditions of these wells, the volume of production, the number of well completions, capital expenditures of other oilfield service companies and the level of workover activity. Drilling and workover activity can fluctuate significantly in a short period of time, particularly in the United States and Canada. The willingness of oil and gas operators to make capital expenditures to explore for and produce oil and natural gas and the willingness of oilfield service companies to invest in capital equipment will continue to be influenced by numerous factors over which we have no control, including:

8

If there is a significant reduction in demand for drilling services, in cash flows of drilling contractors or production companies or in drilling or well servicing rig utilization rates, then demand for the products and services of the combined company after the merger will decline.

Volatile oil and gas prices affect demand for our products.

Oil and gas prices have been volatile since 1990. In general, oil prices approximated $18-22 per barrel from 1991 through 1997, experienced a decline into the low teens in 1998 and 1999, and have generally ranged between $25-50 per barrel since 2000. Spot gas prices generally ranged between $1.80-2.60 per mmbtu of gas from 1991 through 1999, then experienced severe spikes into the $10 range in 2001 and 2003. Absent occasional spikes and dips due to imbalances in supply and demand, prices have generally ranged between $4.00-6.00 per mmbtu during the last two years.

Expectations for future oil and gas prices cause many shifts in the strategies and expenditure levels of oil and gas companies and drilling contractors, particularly with respect to decisions to purchase major capital equipment of the type we manufacture. Industry activity and our revenues have responded slowly to the higher commodity prices that have existed since the second quarter of 2002, presumably due to concerns that these prices will not continue in the current range. Oil and gas prices, which are determined by the marketplace, may fall below a range that is acceptable to our customers, which could reduce demand for our products.

Competition in our industry could ultimately lead to lower revenues and earnings.

The oilfield products and services industry is highly competitive. National Oilwell competes with national, regional and foreign competitors in each of their current major product lines. These competitors may have greater financial, technical, manufacturing and marketing resources than National Oilwell, and may be in a better competitive position. The following competitive actions can each affect our revenues and earnings:

In addition, certain foreign jurisdictions and government-owned petroleum companies located in some of the countries in which we operate have adopted policies or regulations which may give local nationals in these countries competitive advantages. Competition in our industry could lead to lower revenues and earnings.

National Oilwell has aggressively expanded its businesses, and intends to maintain an aggressive growth strategy.

National Oilwell has aggressively expanded and grown its businesses during the past several years, primarily through acquisitions. We anticipate that we will continue to pursue an aggressive growth strategy but we cannot assure you that attractive acquisitions will be available to us at reasonable prices or at all. In addition, we cannot assure you that we will successfully integrate the operations and assets of any acquired business with our own or that our management will be able to manage effectively the increased size of the combined company or operate any new lines of business. Any inability on the part of management to integrate and manage acquired businesses and their assumed liabilities could adversely affect our business and financial performance. In addition, we may need to incur substantial indebtedness to finance future acquisitions. We cannot assure you that we will be able to obtain this financing on terms acceptable to us or at all. Future acquisitions may result in increased depreciation and

9

amortization expense, increased interest expense, increased financial leverage or decreased operating income for the combined company, any of which could cause our business to suffer.

Our operating results have fluctuated during recent years and these fluctuations may continue.

We have experienced fluctuations in quarterly operating results in the past. We cannot assure you that we will realize expected earnings growth or that earnings in any particular quarter will not fall short of either a prior fiscal quarter or investors’ expectations. The following factors, in addition to others not listed, may affect our quarterly operating results in the future:

There are risks associated with our presence in international markets, including political or economic instability and currency restrictions.

Approximately 44% of National Oilwell’s revenues in 2004 were derived from operations outside the United States. National Oilwell’s foreign operations include significant operations in Europe, the Middle East, Africa, Southeast Asia, South America and other international markets. Our revenues and operations are subject to the risks normally associated with conducting business in foreign countries, including uncertain political and economic environments, which 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 compensation. Government-owned petroleum companies located in some of the countries in which we operate have adopted policies, or are subject to governmental policies, giving preference to the purchase of goods and services from companies that are majority-owned by local nationals. As a result of these policies, we may rely on joint ventures, license arrangements and other business combinations with local nationals in these countries. In addition, political considerations may disrupt the commercial relationships between National Oilwell and government-owned petroleum companies.

An impairment of goodwill could reduce the combined company’s earnings.

National Oilwell has recorded approximately $639 million of goodwill on its consolidated balance sheet as of December 31, 2004.We currently expect to record approximately $1,579 million of goodwill upon completion of the merger with Varco, but that estimate is subject to change based upon the final number of shares of National Oilwell common stock issued at the time of closing and the final valuation of Varco’s identified assets and liabilities. Consequently, following the merger, we expect that approximately $2,218 million, representing approximately 38% of the combined company’s consolidated assets on a pro forma as adjusted basis, may be recorded as goodwill. Goodwill is recorded when the purchase price of a business exceeds the fair market value of the tangible and separately measurable intangible net assets. Generally accepted accounting principles requires us to test goodwill for impairment on an annual basis or when events or circumstances occur indicating that goodwill might be impaired. If we were to determine that any of our remaining balance of goodwill was impaired, we would record an immediate charge to earnings with a corresponding reduction in stockholders’ equity and increase in balance sheet leverage as measured by debt to total capitalization.

10

We could be adversely affected if we fail to comply with any of the numerous federal, state and local laws, regulations and policies that govern environmental protection, zoning and other matters applicable to our businesses.

Our businesses are subject to numerous federal, state and local laws, regulations and policies governing environmental protection, zoning and other matters. These laws and regulations have changed frequently in the past and it is reasonable to expect additional changes in the future. If existing regulatory requirements change, we may be required to make significant unanticipated capital and operating expenditures. We cannot assure you that our operations will continue to comply with future laws and regulations. Governmental authorities may seek to impose fines and penalties on us or to revoke or deny the issuance or renewal of operating permits for failure to comply with applicable laws and regulations. Under these circumstances, we might be required to reduce or cease operations or conduct site remediation or other corrective action which could adversely impact our operations and financial condition.

Our businesses expose us to potential environmental liability.

Our businesses expose us to the risk that harmful substances may escape into the environment, which could result in:

Our current and past activities, as well as the activities of our former divisions and subsidiaries, could result in our facing substantial environmental, regulatory and other liabilities. These could include the costs of cleanup of contaminated sites and site closure obligations. These liabilities could also be imposed on the basis of one or more of the following theories:

We may not have adequate insurance for potential environmental liabilities.

While we maintain liability insurance, this insurance is subject to coverage limits. In addition, certain policies do not provide coverage for damages resulting from environmental contamination. We face the following risks with respect to our insurance coverage:

Even a partially uninsured claim, if successful and of significant size, could have a material adverse effect on our consolidated financial statements.

11

Item 2. Properties

National Oilwell owned or leased approximately 268 facilities worldwide as of December 31, 2004, including the following principal manufacturing and administrative facilities:

We own or lease 79 repair and manufacturing facilities that refurbish and manufacture new equipment and parts and approximately 147 distribution service centers worldwide. We believe the capacity of our facilities is adequate to meet demand currently anticipated for 2005.

Item 3. Legal Proceedings

National Oilwell has various claims, lawsuits and administrative proceedings that are pending or threatened, all arising in the ordinary course of business, with respect to commercial, product liability and employee matters. Although no assurance can be given with respect to the outcome of these or any other pending legal and administrative proceedings and the effect such outcomes may have, we believe any ultimate liability resulting from the outcome of such proceedings will not have a material adverse effect on our consolidated financial statements.

Item 4. Submission Of Matters To A Vote Of Security Holders

No matters were submitted to a vote of security holders during the quarter ended December 31, 2004.

Part II

Item 5. Market for Registrant’s Common Equity and Related Stockholder Matters

Market Information

National Oilwell common stock is listed on the New York Stock Exchange (ticker symbol: NOI). The following table sets forth the stock price range during the past three years:

As of March 1, 2005, there were 478 holders of record of National Oilwell common stock. Many stockholders choose to own shares through brokerage accounts and other intermediaries rather than as holders of record so the actual number is unknown but significantly higher. National Oilwell has never paid cash dividends, and none are anticipated during 2005.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

General Overview

We design, manufacture and sell drilling systems, drilling equipment and downhole products as well as distribute maintenance, repair and operating products to the oil and gas industry. Our revenues and operating results are directly related to the level of worldwide oil and gas drilling and production activities and the profitability and cash flow of oil and gas companies and drilling contractors, which in turn are affected by current and anticipated prices of oil and gas. Oil and gas prices have been and are likely to continue to be volatile. See “Risk Factors”.

We conduct our operations through the following segments:

Products and Technology

Our Products and Technology segment designs and manufactures complete land drilling and workover rigs, and drilling related systems for offshore rigs. Technology has increased the desirability of one vendor assuming responsibility for the entire suite of components used in the drilling process, as mechanical and hydraulic components are replaced by or augmented with integrated computerized systems. In addition to traditional components such as drawworks, mud pumps, top drives, derricks, cranes, jacking and mooring systems, and other structural components, we provide automated pipehandling, control and electrical power systems. We have also developed new technology for drawworks and mud pumps applicable to the highly demanding offshore markets. We have made strategic acquisitions during the past several years in an effort to expand our product offering and our global manufacturing capabilities, including new operations in Norway, the United Kingdom and China. Product and Technology revenues are directly dependent on the levels of worldwide drilling activity.

Distribution Services

Our Distribution Services segment provides maintenance, repair and operating supplies and spare parts from our network of distribution service centers to drill site and production locations throughout North America and to offshore contractors worldwide. Products are purchased from numerous manufacturers and vendors, including our Products and Technology segment. We have expanded this business to locations outside North America, including Europe, the Middle East, Southeast Asia, and South America. We have made significant investments in systems, staffing and inventory in the international market and, using our information technology platforms and processes, we can provide complete procurement, inventory management, and logistics services to our customers.

Results of Operations

Operating results by segment are as follows (in millions):

(1) Includes $170 million Hydralift backlog @ 12/31/02

Products and Technology

      Year 2004 versus 2003

Products and Technology revenues in 2004 were $222.4 million (17%) higher than the previous year. Yearly average oil and gas prices in 2004 were $41.37 and $5.95, an increase of 34% and 8% over 2003. These higher oil and gas prices have encouraged many of our customers to order new capital equipment, or refurbish their existing equipment, generating additional capital equipment revenues in 2004 of $72 million. The number of worldwide rigs actively searching for oil and gas increased approximately 10% in 2004 to a yearly average of 2,395 rigs. This metric is a key driver of our noncapital equipment revenues which were $150 million higher in 2004. Drilling spare parts, expendable pumps and related parts, downhole motors and fishing tools, and service work all showed significant increases during 2004. Despite the higher revenues, operating income declined approximately $8 million (5%). Gross margins were negatively impacted by the increase of lower margin capital equipment revenues, higher steel prices during the first half of the year and higher agent commissions. Operating expenses increased primarily due to higher employee benefit costs.

One of our primary metrics is the capital equipment backlog. New orders are added to backlog only when we receive a firm customer purchase order for major drilling rig components or a signed contract related to a construction project. New orders received in 2004 for capital equipment totaled $961 million, far exceeding the previous year’s record of $598 million. The capital equipment backlog was $605 million at December 31,

15

2004, $339 million at December 31, 2003 and $364 million at December 31, 2002. All of the current backlog will be delivered by the end of 2006.

      Year 2003 versus 2002

Revenues in the Products and Technology segment in 2003 increased $397.4 million over the prior year, with virtually all of the increase attributable to our acquisitions of Hydralift and Monoflo. Major international construction projects are generally long-term contracts, thus less susceptible to changes in oil and gas prices or rig count movements. Our revenues from backlog increased $233 million, primarily resulting from the addition of the Hydralift operations. Sales and rentals of downhole motors and fishing tools increased approximately $32 million, primarily due to the resurging North American drilling rig count. Spare part and service revenues accounted for the remaining incremental revenues. Operating income in 2003 increased $38.1 million over 2002 and generated a flow-through percentage of 9.6%. Flow-through, defined as incremental operating profit divided by incremental revenues, is a key financial metric for our company. While we target a flow-through rate of 25% for this group, this was not expected in 2003 as the increased revenues came from acquisitions which in turn included large amounts of overhead and administrative costs. Product mix unfavorably impacted gross margin as the lower margins on the major projects reduced gross margin % by almost 4%. Operating expenses incurred to generate the margins resulting from the incremental sales volume were approximately $81 million higher than the prior year, due primarily to the addition of Hydralift and Monoflo.

The Products and Technology capital equipment backlog was $339 million at December 31, 2003, $364 million at December 31, 2002 and $385 million at December 31, 2001. Backlog at December 31, 2002 includes $170 million acquired in late December through the purchase of Hydralift ASA. Backlog from Hydralift is also contained in subsequent backlog totals but quantification is not possible due to the overlap with products from our other operations.

Distribution Services

      Year 2004 versus 2003

Revenues in 2004 of $905.1 million for the Distribution Services segment established a new record, increasing $113 million (14%) over 2003. The number of drilling rigs actively searching for oil and gas is a key metric for this business. According to the Baker Hughes rig count report, the average number of rigs operating in the world in 2004 continued to climb to levels not seen since 1985. The average rig count in the United States in 2004 was up 15% over the prior year to 1,190 rigs with our U.S. revenues up $49 million (11%). While the Canadian rig count was virtually flat during 2004, our Canadian revenues were up $44 million (24%) primarily due to strong tubular sales and the inclusion of a late 2003 acquisition, Corlac Equipment Ltd., in our Canadian results for the full year. In the international market, our revenue increase of 11% linked favorably with the international rig count increase in 2004 of 8%. From a product perspective, maintenance, repair and operating supplies (“MRO”) products recorded the most growth, a $78 million increase over the prior year. Sales of our manufactured products increased $20 million and tubular products recorded a $15 million increase over 2003. Operating income increased $23.1 million in 2004 to $29.6 million. Excluding the non-recurring clearing account matter recorded in 2003, operating income increased $16.8 million. Margin on the incremental revenues was partially offset by higher distribution service center costs to handle the increased market activity.

      Year 2003 versus 2002

Revenues for the Distribution Services segment increased $105.8 million (15%) over the prior year. North American revenues recorded the largest gains, reflecting the increase in the number of operating rigs. According to the Baker Hughes rig count report, the average number of rigs operating in 2003 in the United

16

States and Canada were 1,032, and 372 — increases of 202 and 106 over the prior year. Canadian revenues were up $37 million, or 24%, while the U.S. revenues improved $51 million, or 14%. We expanded our presence in the international market as we recorded revenue gains of $18 million (12%) over the year 2002, primarily due to an alliance in Indonesia and our new operations in Mexico. Our base margin % remained flat as our customers remained sensitive to price changes, which had no significant effect on 2003 revenues. Substantially all of the 2003 revenue growth was in the maintenance, repair and operating supplies (“MRO”) products. Despite the revenue increase, operating income in 2003 fell $11.6 million to a disappointing $6.5 million. This reduction was primarily due to recording a $6.3 million pre-tax charge related to a clearing account problem uncovered in our purchasing system that had accumulated over a three year period. This amount relates to periods prior to 2003 and we have not restated prior periods as the impact is not considered material. A key financial metric for this low-margin business is “% of operating expenses to revenue,” which remained flat at 18% for 2003. In November 2003, we acquired Corlac Equipment Ltd., a Canadian pump distributor, and their 2003 revenues and operating income were not significant.

Corporate

Corporate charges represent the unallocated portion of centralized and executive management costs. Costs for 2004 totaled $18.4 million, an increase of $5.8 million from the prior year. The majority of this increase is due to expenses incurred in conjunction with our efforts to comply with the Sarbanes Oxley Act of 2002 and consulting fees incurred with various tax initiatives.

Interest Expense

Interest expense incurred in 2004 of $34.4 million is slightly below expense level incurred in the prior year. Our average borrowing cost for the year of 5.6 % was essentially the same as 2003. The $150 million 6 7/8% unsecured Senior Notes will mature on July 1, 2005. In addition, our $175 million unsecured North American revolving credit facility expires July 31, 2005. We plan to arrange financing at reasonable terms and conditions with our existing bank syndication, plus other banks as needed, or utilize surplus cash and certain discretionary credit facilities to refinance these expiring obligations. Interest expense should decline in 2005 due to this repayment.

Year 2003 interest expense of $35.5 million increased $11.4 million from the prior year. Annual interest due on the November 2002 issuance of senior notes accounted for $9.9 million of the increase. Borrowings in Norway attributable to the Hydralift operations incurred approximately $3 million in additional interest which was offset in part by lower borrowing rates on the U.S. revolving credit facility. Our average borrowing cost during 2003 of 5.6% reflected a decrease of 0.8 percentage points from the prior year due to the lower interest rates on the credit facilities.

Interest expense in 2002 totaled $24.1 million, an increase of $1.3 million from the prior year. All of this increase is a direct result of our mid-November 2002 sale of $200 million of 5.65% unsecured senior notes. Our average borrowing cost during 2002 of 6.4% remained the same as 2001.

Other Income (Expense)

The U.S. dollar continued its decline in 2004 against most of the currencies in countries where we operate, especially Canada, Norway and the United Kingdom. We recorded foreign exchange losses of $9.3 million in 2004 and $7.2 million in 2003, primarily related to cash balances and intercompany accounts held in U.S. dollars at these subsidiary locations. The remeasurement of these amounts into the local currency results in an income statement gain or loss, which is offset when the amount is translated back into U.S. currency for consolidation purposes by way of an increase or decrease to Other Comprehensive Income in the equity

17

section of the balance sheet. During 2004 we recorded a $2.7 million gain on the sale of certain non-strategic assets and a $10.7 million gain on the disposal of an equity investment.

Income Taxes

National Oilwell is subject to U.S. federal, state and foreign taxes and recorded a combined tax rate of 15% in 2004, 29% in 2003 and 35% in 2002. The reduction in the 2004 effective tax rate is primarily due to a non-recurring tax credit of $17 million resulting from the release of a valuation allowance related to the American Jobs Creation Act of 2004. We anticipate our effective tax rate for 2005 will approximate 32%.

The reduction in the 2003 effective tax rate was primarily due to the lower tax rate on increased foreign income and the benefit associated with export sales.

Liquidity and Capital Resources

At December 31, 2004, our working capital totaled $737 million, a decrease of $57 million from December 31, 2003. However, the general increase in market activity has increased our working capital needs. An increase of $19 million in receivables and $111 million in inventories has been offset by an increase in accounts payable of $187 million. Our capital equipment contracts have generated a net asset position of $195 million, an increase of $136 million from December 2003. We have recorded $150 million of our debt obligations to a current liability as the 6 7/8 unsecured senior notes will mature on July 1, 2005. Cash has increased $69 million during the year and our principal source of cash is from operations. Our ability to collect our customer receivables and obtain prepayments from our customers to help fund major projects are critical to our cash generation needs. Our primary cash uses include acquisitions, capital expenditures to enhance our existing operations, and repayment of debt obligations.

Total capital expenditures were $39 million during 2004, $32 million in 2003 and $24 million in 2002. The majority of these capital expenditures represent additions and enhancements to the downhole rental tool fleet and information management and inventory control systems. Capital expenditures are expected to approximate $43 million in 2005, slightly below our anticipated depreciation expense in that year, with continued emphasis on rental tools and information technology. We believe we have sufficient existing manufacturing capacity to meet currently anticipated demand through 2005 for our products and services.

At December 31, 2004, we had two committed credit facilities, a North American and a Norwegian facility, totaling $279 million. Both facilities are available for general corporate purposes and acquisitions, including letters of credit and performance bonds.

Our North American facility is a three-year unsecured $175 million revolving credit facility with availability up to $50 million for issuance of letters of credit that expires July 31, 2005. At December 31, 2004, there were no borrowings against this facility and there were $53 million in outstanding letters of credit.

Our Norwegian facility, which expires in 2006, has revolving credit facilities totaling $104 million, with $41 million available for letter of credit purposes. At December 31, 2004, there were no borrowings against this facility and there were $18 million in outstanding letters of credit.

We also have additional uncommitted credit facilities totaling $147 million that are used primarily for letters of credit, bid bonds and performance bonds. At December 31, 2004, there were no borrowings against these additional credit facilities and there were $49 million in outstanding letters of credit and performance bonds.

18

In November 2002, we sold $200 million of 5.65% unsecured senior notes due November 15, 2012. Interest is payable on May 15 and November 15 of each year. In March 2001, we sold $150 million of 6.50% unsecured senior notes due March 15, 2011, with interest payable on March 15 and September 15 of each year. In June 1998, we sold $150 million of 6.875% unsecured senior notes due July 1, 2005, with interest payments due annually on January 1 and July 1.

The $150 million 6 7/8% unsecured senior notes will mature on July 1, 2005. In addition, our $175 million unsecured North American revolving credit facility expires July 31, 2005. We plan to arrange financing at reasonable terms and conditions with our existing bank syndication, plus other banks as needed, or utilize surplus cash and certain discretionary credit facilities to refinance these expiring obligations.

We believe cash generated from operations and amounts available under our existing credit facilities and from other sources of debt will be sufficient to fund operations, working capital needs, capital expenditure requirements and financing obligations. We also believe any significant increase in capital expenditures caused by any need to increase manufacturing capacity can be funded from operations or through debt financing.

The senior notes contain reporting covenants and the credit facilities contain financial covenants and ratios regarding maximum debt to capital and minimum interest coverage. We were in compliance with all covenants governing these facilities at December 31, 2004.

We have not entered into any transactions, arrangements, or relationships with unconsolidated entities or other persons which would materially affect liquidity, or the availability of or requirements for capital resources.

A summary of our outstanding contractual obligations and other commercial commitments at
December 31, 2004 is as follows (in millions):

We intend to pursue additional acquisition candidates, but the timing, size or success of any acquisition effort and the related potential capital commitments cannot be predicted. We expect to fund future cash acquisitions primarily with cash flow from operations and borrowings, including the unborrowed portion of the credit

19

facility or new debt issuances, but may also issue additional equity either directly or in connection with acquisitions. There can be no assurance that acquisition funds will be available at terms acceptable to us.

Inflation has not had a significant impact on National Oilwell’s operating results or financial condition in recent years.

Market Risk Disclosure

We are exposed to changes in foreign currency exchange rates and interest rates. Additional information concerning each of these matters follows:

Foreign Currency Exchange Rates

We have operations in foreign countries, including Canada, Norway and the United Kingdom, as well as operations in Latin America, China and other European countries. The net assets and liabilities of these operations are exposed to changes in foreign currency exchange rates, although such fluctuations generally do not affect income since their functional currency is the local currency. These operations also have net assets and liabilities not denominated in the local currency, which exposes us to changes in foreign currency exchange rates that do impact income. We recorded foreign exchange losses in our income statement of approximately $9.3 million in 2003 and $7.2 million in the prior year, primarily related to cash balances and intercompany accounts held in U.S. dollars at these subsidiary locations. The remeasurement of these amounts into the local currency results in an income statement gain or loss, which is offset when the amount is translated back into U.S. currency for consolidation purposes by way of an increase or decrease to Other Comprehensive Income in the equity section of the balance sheet.. We do not believe that a hypothetical 10% movement in these foreign currencies would have a material impact on our earnings.

Some of our revenues in foreign countries are denominated in US dollars, and therefore, changes in foreign currency exchange rates impact our earnings to the extent that costs associated with those US dollar revenues are denominated in the local currency. In order to mitigate that risk, we may utilize foreign currency forward contracts to better match the currency of our revenues and associated costs. We do not use foreign currency forward contracts for trading or speculative purposes. The counterparties to these contracts are major financial institutions, which minimizes counterparty credit risk.

Interest Rate Risk

Our long term borrowings consist of $150 million in 6.875% senior notes, $150 million in 6.5% senior notes and $200 million in 5.65% senior notes. We had no borrowings under our other facilities at December 31, 2004. Our revolving credit facilities may have borrowings during the year denominated in multiple currencies which could expose us to market risk with exchange rate movements. These instruments carry interest at a pre-agreed upon percentage point spread from either the prime interest rate, LIBOR, NIBOR or EURIBOR. Under our credit facilities, we may, at our option, fix the interest rate for certain borrowings based on a spread over LIBOR, NIBOR or EURIBOR for 30 days to 6 months. Our objective in maintaining a portion of our debt in variable rate borrowings is the flexibility obtained regarding early repayment without penalties and lower overall cost as compared with fixed-rate borrowings.

Critical Accounting Policies and Estimates

The preparation of our financial statements requires us to make certain estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Our estimation process generally relates to potential bad debts, obsolete and slow moving inventory, revenue recognition on long term contracts, value of intangible assets, and deferred income tax accounting. Note 1 to the consolidated financial

20

statements contains the accounting policies governing each of these matters. Our estimates are based on historical experience and on our future expectations that we believe to be reasonable under the circumstances. The combination of these factors result in the amounts shown as carrying values of assets and liabilities in the financial statements and accompanying notes. Actual results could differ from our current estimates and those differences may be material.

We believe the following accounting policies are the most critical in the preparation of our consolidated financial statements:

We maintain an allowance for doubtful accounts for accounts receivables by providing for specifically identified accounts where collectibility is doubtful and a general allowance based on the aging of the receivables compared to past experience and current trends. A majority of our revenues come from drilling contractors, independent oil companies, international oil companies and government-owned or government-controlled oil companies, and we have receivables, some denominated in local currency, in many foreign countries. If, due to changes in worldwide oil and gas drilling activity or changes in economic conditions in certain foreign countries, our customers were unable to repay these receivables, additional allowances would be required.

Allowances for inventory obsolescence are determined based on our historical usage of inventory on-hand as well as our future expectations related to our substantial installed base and the development of new products. Changes in worldwide oil and gas drilling activity and the development of new technologies associated with the drilling industry could require additional allowances to reduce the value of inventory to the lower of its cost or net realizable value.

We recognize revenue on long-term construction contracts using the percentage of completion method and is an output based measure focused on engineering estimates and manufacturing progress. This method is used because we believe this is the most meaningful measurement of the extent of progress toward completion. This methodology requires us to make estimates regarding the total costs of the project, our progress against the project schedule and the estimated completion date, all of which impact the amount of revenue and gross margin we recognize in each reporting period. Changes in job performance, job conditions, and estimated profitability, including those arising from contract penalty provisions, and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Profit incentives are included in revenues when their realization is reasonably assured. Provisions for anticipated losses on uncompleted contracts are recorded in full when such losses become evident.

We account for our defined benefit pension plans in accordance with Statement of Financial Accounting Standards No. 87, Employers’ Accounting for Pensions (FAS 87), which requires that amounts recognized in the financial statements be determined on an actuarial basis. Significant elements in determining our pension income or expense in accordance with FAS 87 are the discount rate assumption and the expected return on plan assets. The discount rate used approximates the weighted average rate of return on high-quality fixed income investments whose maturities match the expected payouts. The expected return on plan assets is based upon the geometric mean of historical returns of a number of different equities, including stocks, bonds and U.S. treasury bills. The assumed long-term rate of return on assets is applied to a calculated value of plan assets, which results in an estimated return on plan assets that is included in current year pension income or expense. The difference between this expected return and the actual return on plan assets is deferred and amortized against future pension income or expense. A substantial portion of our pension amounts relate to our defined benefit plans in the United States, Norway and the United Kingdom. Between the years 2000-2003, we assumed that the expected long-term rate of return on plan assets for these plans would be between 6.3% and 8.5%. Prior to 2001, our actual cumulative long-term rate of return on the pension assets of these plans was in excess of these amounts; however, these plans’ assets have recently earned substantially less than the assumed rates of return. The impact of our pension plans on our 2004 results of operations, cash flow and

21

liquidity has been immaterial but recent actual returns of the plan assets may effect future contributions to the plans and our earnings. The amount of unrecognized losses on pension assets is $21.0 million.

Business acquisitions are accounted for using the purchase method of accounting. The cost of the acquired company is allocated to identifiable tangible and intangible assets based on estimated fair value, with the excess allocated to goodwill. On at least an annual basis, we assess whether goodwill is impaired. Our annual impairment tests are performed at the beginning of the 4th quarter of each year. If we determine that goodwill is impaired, we measure that impairment based on the amount by which the book value of goodwill exceeds its implied fair value. The implied fair value of goodwill is determined by deducting the fair value of a reporting unit’s identifiable assets and liabilities from the fair value of that reporting unit as a whole. Additional impairment assessments may be performed on an interim basis if we encounter events or changes in circumstances that would indicate that, more likely than not, the carrying amount of goodwill has been impaired. The fair value of the reporting units is determined based on internal management estimates which consider multiple valuation techniques.

In accordance with the provisions of SFAS No. 109, Accounting for Income Taxes, we account for income taxes using the asset and liability method. In determining income (loss) for financial statement purposes, we must make certain estimates and judgments. These estimates and judgments affect the calculation of certain tax liabilities and the determination of the recoverability of certain of the deferred tax assets, which arise from temporary differences between the tax and financial statement recognition of revenue and expense. Deferred tax assets are also reduced by a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion or all of the recorded deferred tax assets will not be realized in future periods. In evaluating our ability to recover our deferred tax assets we consider all available positive and negative evidence including our past operating results, the existence of cumulative losses in the most recent years and our forecast of future taxable income. In estimating future taxable income, we develop assumptions including the amount of future state, federal and international pretax operating income, reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we are using to manage the underlying businesses.

We currently have recorded significant valuation allowances that we intend to maintain until it is more likely than not the deferred tax assets will be realized. Other than valuation allowances associated with tax attributes acquired through acquisitions, our income tax expense recorded in the future will be reduced to the extent of decreases in our valuation allowances. The realization of our remaining deferred tax assets is primarily dependent on future taxable income. Any reduction in future taxable income including but not limited to any future restructuring activities may require that we record an additional valuation allowance against our deferred tax assets. An increase in the valuation allowance would result in additional income tax expense in such period and could have a significant impact on our future earnings. If a change in a valuation allowance occurs, which was established in connection with an acquisition, such adjustment may impact goodwill rather than the income tax provision. In addition, the calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations in a multitude of jurisdictions across our global operations. We recognize potential liabilities and record tax reserves for anticipated tax audit issues in the U.S. and other tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes will be due. These tax liabilities are reflected net of related tax loss carryforwards. We adjust these reserves in light of changing facts and circumstances; however, due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. If our estimate of tax liabilities proves to be less than the ultimate assessment, an additional charge to expense would result. If payment of these amounts ultimately proves to be less than the recorded amounts, the reversal of the liabilities would result in tax benefits being recognized in the period when we determine the reserves are no longer necessary. If the tax liabilities relate to tax uncertainties existing at the date of the acquisition of a business, the adjustment of such tax liabilities will result in an adjustment to the goodwill recorded at the date of acquisition.

Recently Issued Accounting Standards

In May 2004, the FASB issued Staff Position No. 106-2, “Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003” (“FSP 106-2”). FSP 106-2 provides guidance on accounting for the effects of the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the “Act”) for employers that sponsor postretirement health care plans that provide prescription drug benefits. FSP 106-2 is effective for the first interim or annual period beginning after June 15, 2004. The adoption of FSP 106-2 did not have a material effect on our financial position, results of operations or cash flows.

In November 2004, the FASB issued Statement of Financial Accounting Standards No. 151, “Inventory Costs — an amendment of ARB 43, Chapter 4” (“SFAS 151”). SFAS 151 clarifies the accounting for abnormal amounts of idle facility expense, freight, handling costs and wasted material. Paragraph 5 of Accounting Research Bulletin (“ARB”) 43, Chapter 4 “Inventory Pricing,” previously stated that “under certain circumstances, items such as idle facility expense, excessive spoilage, double freight, and rehandling costs may be so abnormal as to require treatment as current-period charges.” SFAS 151 requires that those items be recognized as current-period charges regardless of whether they meet the criterion of “so abnormal.” In addition, SFAS 151 requires that the allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS 151 is effective for fiscal years beginning after June 15, 2005. We do not believe the implementation of SFAS 151 will have a material impact on our financial position, results of operations or cash flows.

In December 2004, the FASB issued Statement of Financial Accounting Standards No. 123-Revised 2004 (“Revised SFAS 123”), “Share-Based Payment.” This is a revision of SFAS No. 123, “Accounting for Stock-Based Compensation,” and supersedes APB No. 25, “Accounting for Stock Issued to Employees.” Currently, we do not record compensation expense for stock-based compensation. Under Revised SFAS 123, we will be required to measure the cost of employee services received in exchange for stock based on the grant-date fair value (with limited exceptions). That cost will be recognized over the period during which an employee is required to provide service in exchange for the award (usually the vesting period). The fair value will be estimated using an option-pricing model. Excess tax benefits, as defined in Revised SFAS 123, will be recognized as an addition to paid-in capital. This is effective as of the beginning of the first interim or annual reporting period that begins after June 15, 2005. Revised SFAS 123 permits public companies to adopt its requirements using one of two methods: 1) a “modified prospective” method in which compensation cost is recognized beginning with the effective date (a) based on the requirements of Revised SFAS 123 for all share-based payments granted after the effective date and (b) based on the requirements of Revised SFAS 123 for all awards granted to employees prior to the effective date of Revised SFAS 123 that remain unvested on the effective date, or 2) a “modified retrospective” method which includes the requirements of the modified prospective method described above, but also permits entities to restate based on the amounts previously recognized under Statement 123 for purposes of pro forma disclosures either (a) all prior periods presented or (b) prior interim periods of the year of adoption. We are currently in the process of evaluating the impact of Revised SFAS 123 on our financial statements, including different option-pricing models. The pro forma table in Note 1 of the Notes to Consolidated Financial Statements illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of SFAS 123.

In December 2004, the FASB issued FASB Staff Position No. FAS 109-1, “Application of FASB Statement No. 109, Accounting for Income Taxes, to the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004” (“FSP 109-1”) and FASB Staff Position No. FAS 109-2, “Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of 2004” (“FSP 109-2”). FSP 109-1 clarifies the guidance in FASB Statement of Financial Accounting Standards No. 109, “Accounting for Income Taxes” (“Statement 109”) that applies to the new deduction for qualified domestic production activities under the American Jobs Creation Act of 2004 (the “Act”). FSP 109-1 clarifies that the deduction should be accounted for as a special deduction under Statement 109, not as a tax-rate reduction, because the deduction is contingent on performing activities identified in the Act. As a result, companies qualifying for the special deduction will not have a one-time adjustment of deferred tax assets and liabilities in the period the Act is enacted. FSP 109-2 addresses the effect of the Act’s one-time deduction for qualifying repatriations of foreign earnings. FSP 109-2 allows additional time for companies to determine whether any foreign earnings will be repatriated under the Act’s one-time deduction for repatriated earnings and how the Act affects whether undistributed earnings continue to qualify for Statement 109’s exception from recognizing deferred tax liabilities. FSP 109-1 and FSP 109-2 were both effective upon issuance. We have implemented FSP 109-1 and FSP 109-2 in the quarter ended December 31, 2004 and have included the required disclosures in Note 10 of the Notes to Consolidated Financial Statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders
National-Oilwell, Inc.

We have audited the accompanying consolidated balance sheets of National-Oilwell, Inc. and subsidiaries as of December 31, 2004 and 2003 and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2004. Our audits also included the financial statement schedule listed in the index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of National-Oilwell, Inc. at December 31, 2004 and 2003, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2004, in conformity with U.S generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of National-Oilwell, Inc.’s internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 7, 2005 expressed an unqualified opinion thereon.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

National-Oilwell’s management is responsible for establishing and maintaining adequate internal control over financial reporting. National-Oilwell’s internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

Management has used the framework set forth in the report entitled “Internal Control—Integrated Framework” published by the Committee of Sponsoring Organizations (“COSO”) of the Treadway Commission to evaluate the effectiveness of the Company’s internal control over financial reporting. Management has concluded that the Company’s internal control over financial reporting was effective as of December 31, 2004. Ernst & Young LLP has issued an attestation report on management’s assessment of the Company’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON
INTERNAL CONTROL OVER FINANCIAL REPORTING

The Board of Directors and Shareholders

National-Oilwell, Inc.

We have audited management’s assessment, included in the accompanying Management’s Report on Internal Control over Financial Reporting, that National-Oilwell, Inc. maintained effective internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). National-Oilwell, Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, management’s assessment that National-Oilwell, Inc. maintained effective internal control over financial reporting as of December 31, 2004, is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, National-Oilwell, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2004, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of National-Oilwell, Inc. as of December 31, 2004 and 2003, and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2004 of National-Oilwell, Inc. and our report dated March 7, 2005 expressed an unqualified opinion thereon.

NATIONAL-OILWELL, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Basis of Presentation

Nature of Business

We design, construct, manufacture and sell comprehensive systems, components, and products used in oil and gas drilling and production, as well as distribute products and provide supply chain integration services to the upstream oil and gas industry. Our revenues and operating results are directly related to the level of worldwide oil and gas drilling and production activities and the profitability and cash flow of oil and gas companies and drilling contractors, which in turn are affected by current and anticipated prices of oil and gas. Oil and gas prices have been and are likely to continue to be volatile.

Summary of Significant Accounting Policies

Basis of Consolidation

The accompanying consolidated financial statements include the accounts of National-Oilwell, Inc. and its majority-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. Investments that are not wholly-owned, but where we exercise control, are fully consolidated with the equity held by minority owners and their portion of net income (loss) reflected as minority interest in the accompanying financial statements. Investments in unconsolidated affiliates, over which we exercise significant influence, but not control, are accounted for by the equity method. Investments in which we exercise no control or significant influence would be accounted for under the cost method. Certain reclassifications have been made to the 2003 and 2002 consolidated financial statements in order for them to conform with the 2004 presentation.

Fair Value of Financial Instruments

The carrying amounts of financial instruments including cash and cash equivalents, receivables, and payables approximated fair value because of the relatively short maturity of these instruments. Cash equivalents include only those investments having a maturity date of three months or less at the time of purchase. The carrying values of other financial instruments approximate their respective fair values.

Derivative Financial Instruments

We record all derivative financial instruments at their fair value in our consolidated balance sheet. All derivative financial instruments we hold are designated as cash flow hedges and are highly effective in offsetting movements in the underlying risks. Accordingly, gains and losses from changes in the fair value of derivative financial instruments are deferred and recognized in earnings as the underlying transactions occur. Because our derivative financial instruments are so closely related to the underlying transactions, hedge ineffectiveness is insignificant.

We use foreign currency forward contracts to mitigate our exposure to changes in foreign currency exchange rates on firm sale commitments to better match the local currency cost components of our fixed US dollar contracts. Such arrangements typically have terms between three months and one year, depending upon the customer’s purchase order. We may also use interest rate contracts to mitigate our exposure to changes in interest rates on anticipated long-term debt issuances. These contracts are typically short term in nature. We do not use derivative financial instruments for trading or speculative purposes.

38

Inventories

Inventories consist of oilfield products, manufactured equipment, specialized drilling products and downhole motors and spare parts for manufactured equipment and drilling products. Inventories are stated at the lower of cost or market using the first-in, first-out or average cost methods. Allowances for excess and obsolete inventories are determined based on our historical usage of inventory on-hand as well as our future expectations related to our substantial installed base and the development of new products. The allowance, which totaled $41.2 million and $45.3 million at December 31, 2004 and 2003, is the amount necessary to reduce the cost of the inventory to its estimated realizable value.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Expenditures for major improvements that extend the lives of property and equipment are capitalized while minor replacements, maintenance and repairs are charged to operations as incurred. Disposals are removed at cost less accumulated depreciation with any resulting gain or loss reflected in operations. Depreciation is provided using the straight-line method or declining balance method over the estimated useful lives of individual items. Depreciation expense was $41.6 million, $37.4 million and $25.0 million for the years ending December 31, 2004, 2003 and 2002.

Long-lived Assets

We record impairment losses on long-lived assets used in operations when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. The carrying value of assets used in operations that is not recoverable is reduced to fair value if lower than carrying value. In determining the fair market value of the assets, we consider market trends and recent transactions involving sales of similar assets, or when not available, discounted cash flow analysis.

Assets Held for Sale

In the course of integrating acquisitions and streamlining operations, we have closed certain manufacturing facilities and non-strategic assets. Facilities that are available for immediate sale, under a formal plan that is probable of completion within one year, are classified as held for sale. When we designate an asset as held for sale, we adjust its carrying value to the lower of its current carrying amount or the estimated fair value less costs to sell and stop recording depreciation expense. Carrying values are adjusted to reflect any subsequent deterioration in fair value.

Intangible Assets

Beginning in 2002, we adopted FAS 142 “Accounting for Goodwill and Other Intangible Assets” and accordingly stopped amortizing goodwill that arose from acquisitions before June 30, 2001. On at least an annual basis, we assess whether goodwill is impaired. Our annual impairment tests are performed at the beginning of the 4th quarter of each year and have indicated no impairment. If we determine that goodwill is impaired, we measure that impairment based on the amount by which the book value of goodwill exceeds its implied fair value. The implied fair value of goodwill is determined by deducting the fair value of a reporting unit’s identifiable assets and liabilities from the fair value of that reporting unit as a whole. Additional impairment assessments may be performed on an interim basis if we encounter events or changes in circumstances that would indicate that, more likely than not, the carrying amount of goodwill has been impaired. Fair value of the reporting units is determined based on internal management estimates.

39

Goodwill is identified by segment as follows (in millions):

Identified intangible assets with determinable lives consist primarily of technical drawings acquired in the acquisitions of Hydralift, Mono and Corlac and are being amortized on a straight-line basis over the estimated useful lives of 15-20 years. The balance at December 31, 2004 and 2003 was $36 million and $28 million (net of accumulated amortization of $4 million and $2 million, respectively). Amortization expense of identified intangibles is expected to be approximately $2 million in each of the next five years.

Identified intangible assets with indefinite lives consist primarily of tradenames acquired in the acquisitions of Hydralift, Mono and Corlac. The balance at December 31, 2004 and 2003 was $55 million and $50 million. Indefinite lived intangible assets are not amortized, but are subject to an impairment test on at least an annual basis. An impairment charge would be recognized if the fair value were determined to be less than the carrying amount. Our annual impairment tests have indicated no impairment.

Deferred financing costs are amortized on a straight-line basis over the life of the related debt securities.

Foreign Currency

The functional currency for certain of our foreign operations is the local currency. The cumulative effects of translating the balance sheet accounts from the functional currency into the U.S. dollar at current exchange rates are included in accumulated other comprehensive income. Revenues and expenses are translated at average exchange rates in effect during the period. Certain other foreign operations use the U.S. dollar as the functional currency. Accordingly, financial statements of these foreign subsidiaries are remeasured to U.S. dollars for consolidation purposes using current rates of exchange for monetary assets and liabilities and historical rates of exchange for nonmonetary assets and related elements of expense. Revenue and other expense elements are remeasured at rates that approximate the rates in effect on the transaction dates. For all operations, gains or losses from remeasuring foreign currency transactions into the functional currency are included in income. Net foreign currency transaction losses were $9.3 million, $7.2 million and $0.3 million for the years ending December 31, 2004, December 31, 2003 and December 31, 2002, and are included in other income(expense) in the accompanying statement of operations. These losses are primarily related to cash balances and intercompany accounts held in U.S. dollars at these subsidiary locations. The remeasurement of these amounts into the local currency results in an income statement gain or loss, which is offset when the amount is translated back into U.S. currency for consolidation purposes by way of an increase or decrease to Other Comprehensive Income in the equity section of the balance sheet.

40

Revenue Recognition

Product and service sales are recognized on purchase orders or contracts when product delivery has occurred or services have been rendered, pricing is fixed or determinable, and collection is reasonably assured. Our arrangements do not include right of return or other similar provisions or other significant post delivery obligations. Customer advances or deposits are deferred and recognized as revenue when we have completed all of our performance obligations related to the sale. The amounts billed for shipping and handling costs are included in revenue and related costs are included in costs of sales.

Contracts to design and construct complex rig packages to a customers’ specifications are recorded on the percentage-of-completion method using an output based measure focused on engineering estimates and manufacturing progress. This method is used because we believe this is the most meaningful measurement of the extent of progress toward completion. This methodology requires us to make estimates regarding the total costs of the project, our progress against the project schedule and the estimated completion date, all of which impact the amount of revenue and gross margin we recognize in each reporting period. Contract costs include all direct material, labor and subcontract costs. Changes in job performance, job conditions, and estimated profitability, including those arising from contract penalty provisions, and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Profit incentives are included in revenues when their realization is reasonably assured. Provisions for anticipated losses on uncompleted contracts are recorded in full when such losses become evident.

The asset, “Costs in excess of billings,” represents revenues recognized in excess of amounts billed. The liability, “Billings in excess of costs,” represents billings in excess of revenues recognized.

Income Taxes

The liability method is used to account for income taxes. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more likely than not to be realized.

Concentration of Credit Risk

We grant credit to our customers, which operate primarily in the oil and gas industry. Concentrations of credit risk are limited because we have a large number of geographically diverse customers, thus spreading trade credit risk. We control credit risk thorough credit evaluations, credit limits and monitoring procedures. We perform periodic credit evaluations of our customers’ financial condition and generally do not require collateral, but may require letters of credit for certain international sales. Credit losses are provided for in the financial statements. We maintain an allowance for doubtful accounts for accounts receivables by providing for specifically identified accounts where collectibility is doubtful and an additional allowance based on the aging of the receivables compared to past experience and current trends. Accounts receivable are net of allowances for doubtful accounts of approximately $12.8 million and $18.3 million at December 31, 2004 and December 31, 2003, respectively.

Stock-Based Compensation

We use the intrinsic value method in accounting for our stock-based employee compensation plans.

Assuming that we had accounted for our stock-based compensation using the alternative fair value method of accounting under FAS No. 123 and amortized the fair value to expense over the option’s vesting period, our net income and net income per share would have been (in millions, except per share data):

41

These pro forma results may not be indicative of future effects.

Environmental Liabilities

When environmental assessments or remediations are probable and the costs can be reasonably estimated, remediation liabilities are recorded on an undiscounted basis and are adjusted as further information develops or circumstances change.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect reported and contingent amounts of assets and liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Net Income Per Share

The following table sets forth the computation of weighted average basic and diluted shares outstanding (in millions):

In addition, we had stock options outstanding that were anti-dilutive totaling 0.8 million at December 31, 2004, 2.3 million at December 31, 2003, and 1.6 million at December 31, 2002.

Recently Issued Accounting Standards

In May 2004, the FASB issued Staff Position No. 106-2, “Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003” (“FSP 106-2”). FSP 106-2 provides guidance on accounting for the effects of the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the “Act”) for employers that sponsor postretirement health care plans that provide prescription drug benefits. FSP 106-2 is effective for the first interim or annual period beginning after June 15, 2004. The adoption of FSP 106-2 did not have a material effect on our financial position, results of operations or cash flows.

In November 2004, the FASB issued Statement of Financial Accounting Standards No. 151, “Inventory Costs — an amendment of ARB 43, Chapter 4” (“SFAS 151”). SFAS 151 clarifies the accounting for abnormal amounts of idle facility expense, freight, handling costs and wasted material. Paragraph 5 of Accounting Research Bulletin (“ARB”) 43, Chapter 4 “Inventory Pricing,” previously stated that “under certain circumstances, items such as idle facility expense, excessive spoilage, double freight, and rehandling costs may be so abnormal as to require treatment as current-period charges.” SFAS 151 requires that those items be recognized as current-period charges regardless of whether they meet the criterion of “so abnormal.” In addition, SFAS 151 requires that the allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS 151 is effective for fiscal years beginning after June 15, 2005. We do not believe the implementation of SFAS 151 will have a material impact on our financial position, results of operations or cash flows.

In December 2004, the FASB issued Statement of Financial Accounting Standards No. 123-Revised 2004 (“Revised SFAS 123”), “Share-Based Payment.” This is a revision of SFAS No. 123, “Accounting for Stock-Based Compensation,” and supersedes APB No. 25, “Accounting for Stock Issued to Employees.” Currently, we do not record compensation expense for stock-based compensation. Under Revised SFAS 123, we will be required to measure the cost of employee services received in exchange for stock based on the grant-date fair value (with limited exceptions). That cost will be recognized over the period during which an employee is required to provide service in exchange for the award (usually the vesting period). The fair value will be estimated using an option-pricing model. Excess tax benefits, as defined in Revised SFAS 123, will be recognized as an addition to paid-in capital. This is effective as of the beginning of the first interim or annual reporting period that begins after June 15, 2005. Revised SFAS 123 permits public companies to adopt its requirements using one of two methods: 1) a “modified prospective” method in which compensation cost is recognized beginning with the effective date (a) based on the requirements of Revised SFAS 123 for all share-based payments granted after the effective date and (b) based on the requirements of Revised SFAS 123 for all awards granted to employees prior to the effective date of Revised SFAS 123 that remain unvested on the effective date, or 2) a “modified retrospective” method which includes the requirements of the modified prospective method described above, but also permits entities to restate based on the amounts previously recognized under Statement 123 for purposes of pro forma disclosures either (a) all prior periods presented or (b) prior interim periods of the year of adoption. We are currently in the process of evaluating the impact of Revised SFAS 123 on our financial statements, including different option-pricing models. The pro forma table in Note 1 of the Notes to Consolidated Financial Statements illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of SFAS 123.

In December 2004, the FASB issued FASB Staff Position No. FAS 109-1, “Application of FASB Statement No. 109, Accounting for Income Taxes, to the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004” (“FSP 109-1”) and FASB Staff Position No. FAS 109-2, “Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of 2004” (“FSP 109-2”). FSP 109-1 clarifies the guidance in FASB Statement of Financial Accounting Standards No. 109, “Accounting for Income Taxes” (“Statement 109”) that applies to the new deduction for qualified domestic production activities under the American Jobs Creation Act of 2004 (the “Act”). FSP 109-1 clarifies that the deduction should be accounted for as a special deduction under Statement 109, not as a tax-rate reduction, because the deduction is contingent on performing activities identified in the Act. As a result, companies qualifying for the special deduction will not have a one-time adjustment of deferred tax assets and liabilities in the period the Act is enacted. FSP 109-2 addresses the effect of the Act’s one-time deduction for qualifying repatriations of foreign earnings. FSP 109-2 allows additional time for companies to determine whether any foreign earnings will be repatriated under the Act’s one-time deduction for repatriated earnings and how the Act affects whether undistributed earnings continue to qualify for Statement 109’s exception from recognizing deferred tax liabilities. FSP 109-1 and FSP 109-2 were both

43

effective upon issuance. We have implemented FSP 109-1 and FSP 109-2 in the quarter ended December 31, 2004 and have included the required disclosures in Note 10 of the Notes to Consolidated Financial Statements.

2. Acquisitions

On August 11, 2004, we agreed to combine our businesses with Varco International, Inc. by merging Varco with and into National Oilwell, with National Oilwell continuing as the surviving corporation. Consummation of the merger requires approval by the stockholders of both companies and also approval from various regulatory agencies. We anticipate completion of the merger during March 2005.

Year 2004

We spent $2.8 million during 2004 acquiring assets or companies, with the largest being a distribution operation in Australia.

Year 2003

On January 16, 2003, we acquired the Mono pumping products business from Halliburton Energy Services for approximately $91 million, consisting of $24 million in cash and 3.2 million shares of our common stock valued at $67 million. During the remainder of 2003 we made eight other acquisitions representing cash outlays totaling $54 million primarily expanding our Distribution network.

Year 2002

On December 18, 2002, we completed a cash tender offer for 92% of the common shares of Hydralift ASA, a Norwegian based company specializing in the offshore drilling equipment industry. By December 31, 2002, we had substantially completed the acquisition of the remaining shares for a total purchase price, including the assumption of debt and net of cash acquired, of approximately $300 million. The results of Hydralift’s operations have been included in our income statement since the acquisition date.

During 2002 we also acquired three other businesses, primarily within our Products and Technology segment, for approximately $17 million in cash.

5. Long-Term Debt

      Long-term debt consists of (in millions):

At December 31, 2004, we had two committed credit facilities, a North American and a Norwegian facility, totaling $279 million. Both facilities are available for general corporate purposes and acquisitions, including letters of credit and performance bonds.

Our North American facility is a three-year unsecured $175 million revolving credit facility with availability up to $50 million for issuance of letters of credit that expires July 31, 2005. At December 31, 2004, there were no borrowings against this facility and there were $53 million in outstanding letters of credit.

Our Norwegian facility, which expires in 2006, has revolving credit facilities totaling $104 million, with $41 million available for letter of credit purposes. At December 31, 2004, there were no borrowings against this facility and there were $18 million in outstanding letters of credit.

We also have additional uncommitted credit facilities totaling $147 million that are used primarily for letters of credit, bid bonds and performance bonds. At December 31, 2004, there were no borrowings against these additional credit facilities and there were $49 million in outstanding letters of credit and performance bonds.

In November 2002, we sold $200 million of 5.65% unsecured senior notes due November 15, 2012. Interest is payable on May 15 and November 15 of each year. In March 2001, we sold $150 million of 6.50% unsecured senior notes due March 15, 2011, with interest payable on March 15 and September 15 of each year. In June 1998, we sold $150 million of 6.875% unsecured senior notes due July 1, 2005, with interest payments due annually on January 1 and July 1.

45

The $150 million 6 7/8% unsecured senior notes will mature on July 1, 2005. In addition, our $175 million unsecured North American revolving credit facility expires July 31, 2005. We plan to arrange financing at reasonable terms and conditions with our existing bank syndication, plus other banks as needed, or utilize surplus cash and certain discretionary credit facilities to refinance these expiring obligations.

The senior notes contain reporting covenants and the credit facilities contain financial covenants and ratios regarding maximum debt to capital and minimum interest coverage. We were in compliance with all covenants governing these facilities at December 31, 2004.

6. Employee Benefit Plans

We have benefit plans covering substantially all of our employees. Defined-contribution benefit plans cover most of the U.S. and Canadian employees and benefits are based on years of service, a percentage of current earnings and matching of employee contributions. Employees in our Norwegian operations can elect to participate in a defined-contribution plan in lieu of a local defined benefit plan. For the years ended December 31, 2004, 2003 and 2002, expenses for defined-contribution plans were $14.2 million, $13.1 million and $9.1 million, and all funding is current.

Certain retired or terminated employees of predecessor or acquired companies participate in a defined benefit plan in the United States. None of the participants in this plan are eligible to accrue benefits.
