     Sales of the Company's products depend on the level of construction of
new drilling rigs and the replacement and upgrading of equipment for existing
rigs, particularly for offshore rigs and intermediate to deep land rigs (rigs
designed for drilling in excess of 8,000 feet). The level of construction of
drilling rigs and the rate at which equipment on existing rigs is replaced or
upgraded depends, in substantial part, on the level of worldwide exploration and
development drilling activity. Rental revenue, which is generated predominately
by the M/D Totco Division, is directly related to the level of drilling
activity, particularly in the U.S. and Canada. Sales of equipment and sales and
rentals of instrumentation products have also depended on the design,
development and successful introduction of new products for the drilling
industry. Equipment and instrumentation are also sold to existing rigs for use
as spare or replacement parts.

     The level of worldwide drilling activity can be influenced by numerous
factors, including the prices of oil and gas, economic and political conditions,
finding and development costs of oil companies, development of alternative
energy sources, availability of equipment and materials, availability of new
onshore and offshore acreage or concessions, and new and continued governmental
regulations regarding environmental protection, taxation, price controls and
product allocations. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

The Drilling Process

                                                                               1
<PAGE>
 
     An oil or gas well is drilled by a bit attached to the end of the
drill stem which is made up of 30-foot lengths of drill pipe joined by threaded
connections known as "tool joints." Heavy drill collars at the bottom of the
drill stem put weight on the bit. Using the conventional rotary drilling method,
the drill stem is turned from the rotary table in the floor of the drilling rig
by torque applied to the "kelly" (a square or hexagonal section of pipe located
at the top of the drill stem) by means of the master bushing and kelly bushing.
During the drilling process heavy fluids ("drilling mud") are pumped down
through the drill stem and forced out through the bit. The drilling mud returns
to the surface through the hole area surrounding the drill stem, carrying with
it the cuttings drilled out by the bit. The cuttings are removed from the mud by
a filtering system and the mud is continuously recirculated back into the hole.
The drilling mud also serves to contain pressure surges ("kicks") that may
intrude into the formation.

     As the hole depth increases, the kelly must be removed frequently so
that additional 30-foot sections of pipe can be added to the drill stem, which
may reach lengths in excess of five miles. When the bit becomes dull, the entire
drill stem is pulled out of the hole and disassembled, the disconnected sections
of pipe are set aside or "racked," the old bit is replaced and the drill stem
reassembled and lowered back into the hole (a process called "tripping"). During
drilling and tripping operations, tool joints must be screwed together and
tightened ("spun in" and "made up"), and loosened and unscrewed ("broken out"
and "spun out"). When the hole has reached certain depths, all of the drill pipe
is pulled out of the hole and larger diameter pipe known as casing is lowered
into the hole and cemented in place in order to protect against collapse and
contamination of the hole.

     The raising and lowering of the drill stem while drilling or tripping,
and the lowering of casing into the well bore, are accomplished with the rig's
hoisting system. A conventional hoisting system is a block and tackle mechanism
and the derrick must have sufficient structural integrity to support the entire
weight of the drill stem or casing string.

     During the drilling process it is possible for formation fluids, such
as natural gas, water or oil, to get into the wellbore creating additional
pressure which, if not controlled, could lead to a "blowout" of the well. To
prevent blowouts a series of high-pressure valves known as blowout preventers
("BOPs") are positioned at the top of the well and, when activated, form
pressure tight seals which prevent the escape of fluids. When closed,
conventional BOPs prevent normal rig operations and are activated only if
drilling mud and normal well control procedures cannot safely contain the
pressure. BOPs must be designed to contain pressure of up to 15,000 psi.

     After the well has reached its total depth and the final section of
casing has been set, the drilling rig is moved off of the well and the well is
prepared to begin producing oil or gas in a process known as "well completion."
A producing well may undergo workover procedures to extend its life and increase
its production rate.

     The Top Drive Drilling System, originally introduced by Varco in 1982,
significantly alters the traditional drilling process. Using the Top Drive
Drilling System, the drill stem is rotated from its top by means of a large
electric motor. This motor is affixed to rails installed in the derrick and
traverses from near the top of the derrick to the rig floor as the drill stem
penetrates the earth. Therefore, the Top Drive eliminates the use of the rotary
table for drilling. Components of the Top Drive also are used to connect
additional lengths of pipe to the drill stem during drilling operations.

Varco Systems

     The Varco Systems Division designs and manufactures integrated systems for
rotating and handling the various sizes and types of pipe used on a drilling
rig.  They are designed to enhance the safety and productivity of the drilling
rig through mechanization and automation.

     The Varco Top Drive Drilling System ("TDS") combines elements of pipe
handling tools, as well as hoisting and rotary equipment, in a single system.
Torque to turn the drill stem is imparted directly by 

                                                                               2
<PAGE>
 
means of a large electric motor which moves up and down along rails installed in
the derrick and into which the drill stem is connected. During drilling
operations, elements of the TDS perform functions such as spinning-in and 
making-up tool joints. It also incorporates a drill pipe elevator, providing the
capability to maneuver a stand of pipe into position to be added to the drill
string when drilling, or to hold and hoist the entire drill stem. Drilling with
a Top Drive Drilling System provides several advantages over conventional
drilling. It enables drilling with three lengths of drill pipe, reducing by two-
thirds the time spent in making connections of drill pipe. In addition it
facilitates "horizontal" and "extended reach" drilling (the practice of drilling
wells which deviate substantially from the vertical) by providing the ability to
rotate the pipe as it is removed from, or replaced into, the hole, thus reducing
friction and the incidence of pipe sticking. The Top Drive Drilling System also
increases the safety of drilling operations.

     The Top Drive Drilling System has demonstrated substantial economic
advantages.  Users of the system generally report reductions in drilling time
ranging from 20% to 40%.  By facilitating extended reach drilling, the TDS
increases the area which can be drilled from a given location, such as a fixed
platform or man-made island.  Thus, the production from a given reservoir of oil
can be increased and the number of costly fixed platforms required to develop
the field can be minimized.

     The Top Drive Drilling System has evolved continuously since its
initial introduction.  Today, the Top Drive product line includes several
models, each designed to satisfy specific customer requirements.  The version
initially introduced to the market in 1982, the TDS-3, remains a part of the
product line. The TDS-4, introduced in 1990, is a two-speed model which permits
a variation in speed and torque that is desirable for differing drilling
conditions.  The TDS-6S, first delivered in 1991,  is a dual motor version which
provides double the power and torque of a single motor unit.  The TDS-7S,
initially introduced in 1993, is powered by an alternating current ("AC") motor
instead of the direct current ("DC") motor used on previous models.  In the
fourth quarter of 1997 the first TDS-8S was delivered.  The TDS-8S is the AC
motor version of Varco Systems' most popular Top Drive, the TDS-4S.  The AC
system offers lower maintenance cost, as well as providing higher torque for
longer periods and a running speed more than twice that of conventional DC motor
powered systems. Six TDS-8S units were delivered in 1998.

     The Integrated Drilling System ("IDS") is an adaptation of the Top
Drive concept which is more compact than its Top Drive counterparts, and which
is affixed to a separately installed torque tube rather than rails permanently
installed in the derrick.  It can be used on rigs which are smaller and which do
not have the structural integrity necessary to support a traditional Top Drive.

     In 1995 the TDS-9S was introduced.  It is powered by dual AC motors,
is reduced in length and rides on a separately installed torque tube.  For these
reasons it is especially well suited for sale or rental to the conventional land
rig market, where portability is critical. It is designed for ease of
installation in existing derricks, can be rigged up and rigged down in a matter
of hours, and is easily transported from one location to another.  During 1997
the TDS-10S was introduced. The TDS-10S is a smaller version of the TDS-9S
designed for use in a variety of smaller land and workover rig applications. The
TDS-10S has a 250-ton hoisting capacity as compared to the 400-ton hoisting
capacity of the TDS-9S.  In 1998 a higher hoisting capacity AC powered Top Drive
was introduced, the TDS-11S.  The TDS-11S has a hoisting capacity of 500 tons.
Two TDS-10S units and ten TDS-11S units were sold in 1998.

     Pipe racking systems are used to handle drill pipe, casing and other types
of pipe (collectively "tubulars") on a drilling rig.  Vertical pipe racking
systems move drill pipe and casing between the well and a storage ("racking")
area on the rig floor.  Horizontal racking systems are used to handle tubulars
while stored horizontally (for example, on the pipe deck of an offshore rig) and
transport it up to the rig floor and raise it to a vertical position from which
it may be passed to a vertical racking system.

     Mechanical vertical pipe racking systems include those developed and sold
by BJ Machinery prior to its acquisition by Varco in 1988.  Such systems reduce,
but do not eliminate, the manual effort involved in pipe handling.  The Pipe
Handling Machine ("PHM"), introduced by Varco in 1985, provides a fully
automated mechanism for handling and racking of drill pipe and drill collars
during drilling and tripping 

                                                                               3
<PAGE>
 
operations. It incorporates the spinning and torquing functions of the Automated
Roughneck with the automatic hoisting and racking of disconnected sections of
pipe. These functions are integrated via computer controlled sequencing, and the
Pipe Handling Machine is operated by a person in an environmentally secure
cabin.

     The Automated Roughneck is an automated version of the Iron Roughneck(R),
which was originally introduced by Varco in 1976.  It is a microprocessor
controlled device which automatically performs the torquing and spinning
functions required to connect and disconnect sections of drill pipe during
drilling and tripping operations, as well as during the setting of casing.

     The Pipe Racking System ("PRS") is a semi-automated vertical pipe racking
system which has evolved from the "Star" system to which the Company acquired
the rights in 1990.  When used in conjunction with an Automated Roughneck, it
provides an alternative to the more fully automated PHM.  Like the PHM, it is
operated remotely from the driller's cabin by a single operator, but it requires
more operator intervention.  Its design makes it more easily adapted to a land
rig or for retrofitting to an existing offshore rig.  The current version of the
PRS was introduced in 1996.  Seventeen units of the PRS were delivered in 1998.

     Vertical pipe racking systems are used predominantly on offshore rigs and
are virtually mandatory on floating rigs such as semisubmersibles. Horizontal
pipe racking systems were introduced by Varco in 1993.  They include the Pipe
Deck Machine ("Pipe Mite") which is used to manipulate and move tubulars while
stored in a horizontal position; the Pipe Conveyor which transports sections of
pipe to the rig floor; and a Pickup Laydown System ("PLS") which raises the pipe
to a vertical position for transfer to a vertical racking system.  These
components may be employed separately, or incorporated together to form a
complete horizontal racking system, known as the Pipe Transfer System ("PTS").

Varco BJ

     The Varco BJ product line consists of a full complement of conventional rig
tools and equipment. It was formed by the combination of the original Varco oil
tool products and the related products acquired in the BJ Machinery and the
Martin-Decker acquisitions. These products include pipe handling tools, hoisting
equipment and rotary equipment.

     Varco's pipe handling tools are designed to enhance the safety, efficiency
and reliability of pipe handling operations. Many of these tools have provided
innovative methods of performing the designated task through mechanization of
functions previously performed manually.

     Varco BJ manufactures various tools used in the making up and breaking out
of drill pipe, including spinning wrenches, manual tongs, torque wrenches and
kelly spinners. The spinning wrench is a tool used to screw together and unscrew
sections of drill pipe. Powered pneumatically or hydraulically, it replaces a
hazardous device known as a spinning chain. Manual tongs are used to make up or
break out tool joints, while the torque wrench is a hydraulically powered device
which performs this function with enhanced safety and precision. The kelly
spinner is a pneumatically or hydraulically powered tool used to connect and
disconnect the kelly to and from the drill stem as additional lengths of pipe
are added while drilling.

     The Company also manufactures other tools used in various pipe handling
functions. Slips are gripping devices which hold pipe or casing in suspension
while in the hole, and they may be either manual, spring or hydraulically
operated. Other products, which include safety clamps, casing bushings and
casing bowls, are used to hold and guide drill pipe or casing while in the hole.

     When drilling, tripping or setting casing, lengths of pipe must be hoisted
into position above the hole, lowered into or lifted from the hole and held in
suspension while in the hole. Hoisting equipment includes devices used to grip
and hold various types of pipe ("tubulars") while being raised or lowered. 

                                                                               4
<PAGE>
 
Drill pipe elevators are used to hold lengths of drill pipe as they are hoisted
into position to be attached to the drill stem, and to hold the entire drill
stem as it is lowered into or lifted from the hole. Similarly, casing elevators
and spiders are gripping devices used to hold the casing as additional lengths
are added and lowered into the hole. Links are elongated steel forgings from
which the elevator is suspended and which, in turn, hangs from beneath the hook
which is connected to the hoisting mechanism of the drilling rig. The Company
manufactures elevators to accommodate a variety of tubulars, as well as a
complete line of links and hooks, together with casing elevators and spiders, to
handle a variety of casing sizes and accommodate casing weighing up to 1,000
tons.

     Varco BJ expanded its casing spider line in 1994 with the introduction of
the Flush Mounted Spider ("FMS 375"). It is designed to improve safety and
efficiency during casing operations, by eliminating scaffolding which otherwise
must be used as a raised work platform for the rig crew.

     During  1996 the Varco BJ product line was further expanded with the
introduction of the BX Hydraulic Elevator and the PS 21 and PS 30 Hydraulic
Power Slips.  The BX Hydraulic Elevator increases safety and eliminates the
normal rig complement of several different types and sizes of elevators through
the use of removable bushings. The PS 21 and PS 30 Power Slips improve both
safety and rig efficiency by permitting the handling of all sizes and types of
tubulars with a single tool and by incorporating the FMS concept. During 1998,
46 BX elevators, 25 PS 21's and 19 PS 30's were delivered to customers.

     Rotary equipment products consist of kelly bushings and master bushings.
The kelly bushing applies torque to the kelly to rotate the drill stem and fits
in the master bushing which is turned by the rotary table on the floor of the
rig. Varco BJ produces kelly bushings and master bushings for most sizes of
kellys and makes of rotary tables.

     In 1998 Varco BJ introduced the Rotary Support Table for use on rigs with
Top Drive Drilling Systems. The Rotary Support Table is used in concert with the
TDS to eliminate the need for the larger conventional rotary table. Thirteen
units were delivered in 1998.

     A substantial portion of the Company's sales in some of the Varco BJ
products is attributable to sales of replacement parts which are subject to
normal wear and to sales of spare parts. Replacement parts for kelly bushings,
rotary slips, casing tools and spinning wrenches are a material part of the
sales of those product lines.

M/D Totco

     The M/D Totco Division designs, manufactures and sells or rents hydraulic
and electronic  instrumentation and control systems, primarily for use in oil
and gas well drilling operations; and, to a lesser extent, provides
instrumentation to certain general industrial markets and for use in non-
drilling related oilfield applications.

     A drilling rig instrumentation package is generally comprised of four
elements: (1) sensors, which measure selected variables at the point of origin;
(2) a mechanical or electronic means of transmitting that data to the display
device; (3) a display, which may range in sophistication from a simple gauge to
a computer terminal or workstation; and (4) a method for permanently recording
and/or electronically transmitting the data for subsequent review and analysis.
This equipment must be sufficiently rugged to withstand the hostile
environmental conditions of a drilling rig.

     The driller relies on certain instruments to provide information critical
to the operation of the drilling rig. At a minimum, this information includes
the status of such basic data as weight-on-bit, rotary RPM, rotary torque, hook
load, rate of penetration, mud pit volume, and mud flow. The indicators which
display this data are generally contained in a common housing called a drilling
console. A drilling console may range in sophistication from a collection of
analog gauges to a microprocessor based system such as the M/D Totco "Spectrum
1000".

                                                                               5
<PAGE>
 
     Computer based electronic data acquisition systems provide real-time
analysis and display of the various drilling data at the driller's station, as
well as other locations around the rig. In 1991 M/D Totco introduced the TOTAL
system, a computer-based data acquisition system incorporating up-to-date
electronic technology with comprehensive analytical capabilities. The emphasis
in TOTAL is on the analysis and interpretation of data via computer software, so
that the information displayed to the driller enables him to operate the rig
more safely and efficiently.

     In 1992, the Company licensed from the Sedco Forex Division of Schlumberger
Limited the rights to develop, manufacture and market the MDS(TM) System, an
advanced computer-based drilling information and alarm system which is
integrated with TOTAL. Its software programs incorporate the knowledge and
experience of drilling personnel and engineers to provide critical information
in a user-friendly format.

     In addition to MDS(TM) a number of additional analytical capabilities have
been developed for the TOTAL System. Drill-Off, a computerized drilling
optimization program was jointly developed by M/D Totco and Exxon. An agreement
with Schlumberger's Anadril Division, authorizing M/D Totco to manufacture and
market a sophisticated kick detection system known as Kick-Alert(SM) was
finalized in 1993. A joint effort by M/D Totco and British Petroleum to
incorporate a software program known as Early Kick Detection (EKD) on the TOTAL
system was completed in 1995. An exclusive Worldwide Marketing agreement with
Logware, Inc. to market a Windows(TM) based drilling information system was
completed in 1993.

     The TOTAL system is designed so that it may be scaled to the requirements
of a particular drilling operation. For relatively routine drilling requirements
it can represent a cost-effective means of providing basic information; however,
it can be expanded to encompass the full range of analytical capability for
complex and costly offshore drilling.

     Other drilling related products of M/D Totco include drift indicators,
which are used to measure and record the degree of drift of the well from
vertical; mechanical recorders, which produce a permanent record in chart form
when an electronic system is not being used; drilling control systems (auto-
drillers) which automatically maintain a constant pressure on the drill bit, and
drilling chokes which provide a remotely actuated method of controlling "kicks."

     In 1997 M/D Totco also introduced the Varco Integrated Control and
Information System ("V-ICIS"), a computer-based system which combines the
physical control of all of Varco's automated equipment and potentially that of
third parties, into a common, user-friendly system which also integrates the
analytical capabilities of the TOTAL system. Five V-ICIS systems were delivered
in 1998.

     Products of the M/D Totco Division used outside  the drilling process
include load and radius indicating systems for pedestal type cranes, anchor
tension monitoring systems for use in mooring and positioning applications, and
specialty scales for industrial use.

     In 1993, the Company acquired all of the outstanding shares of Metrox,
Inc., a manufacturer of strain gauge systems. The acquisition of strain gauge
technology provides further penetration into the industrial crane and weight
monitoring markets as well as enhancing the overall M/D Totco sensor technology.
Strain gauge sensors provide an extremely precise measurement of many factors
critical to the drilling operations.

     Drilling consoles, and recently, the V-ICIS product, are typically sold as
original equipment to the rig manufacturer. However, electronic drilling
consoles may be sold as upgrades to existing rigs. In the United States and
Canada, most other instrumentation products are rented to the drilling
contractor or oil company when necessary, and are therefore not permanently
installed on the rig. Internationally, nearly all 

                                                                               6
<PAGE>
 
instrumentation equipment is sold to the rig owner and becomes a permanent part
of the drilling rig. A significant portion of the sales of some instrumentation
product lines is in spare and replacement parts.

Shaffer

     The Shaffer Division designs, manufactures, sells and distributes pressure
control equipment (including ram blowout preventers, annular or spherical
blowout preventers and rotating blowout preventers); blowout preventer control
systems; riser; and motion compensation systems (including riser tensioners,
drillstring compensators and crown mounted compensators).

     Blowout preventers ("BOPs") are devices used to seal the space between the
drill string and the borehole to prevent an uncontrolled flow of formation
fluids and gases. Shaffer manufactures three types of BOPs. Ram and annular BOPs
are back-up devices and are activated only if other techniques for controlling
pressure in the well bore are inadequate. When closed, these devices prevent
normal rig operations. Ram BOPs seal the wellbore by hydraulically closing rams
against each other across the wellbore.  Specially designed packers seal around
specific sizes of pipe in the wellbore, shear pipe in the wellbore or close off
an open hole. Annular BOPs seal the wellbore by hydraulically closing a rubber
packing unit around the drill pipe or kelly or by sealing against itself if
nothing is in the hole. The rotating BOP allows operators to drill or strip into
or out of the well at low pressures without interrupting normal operations.

     Shaffer expanded its BOP line in 1995 with the introduction of a system for
achieving Pressure Control While Drilling (PCWD(R)). This new BOP allows normal
drilling operations to proceed while controlling pressures up to 2,000 psi, and
will operate as a normal Spherical BOP at pressures up to 5,000 psi. During
1998, PCWD revenue was approximately $1.5 million.

     In 1998 Shaffer introduced the "NXT" ram type BOP which eliminates door
bolts providing weight and space savings. Its unique features make subsea
operation more efficient though faster ram configuration changes without
tripping the stack.   Shaffer has booked three orders for NXTs, all of which are
expected to be delivered in 1999.

     Shaffer sells conventional BOP control systems under the registered
trademark Koomey(R). The Koomey control system is hydraulically actuated and is
used to remotely operate BOPs and associated valves for both land systems and
offshore systems. With the recent increase in deep-water drilling depths,
traditional hydraulic control systems are inadequate to activate BOPs, which
rest on the ocean floor and may be 5,000 feet or more below the surface. In
1997, Shaffer introduced the IVth Generation MUX, an electronic control system
designed specifically for deep-water applications. Twelve such systems were
delivered in 1998.

     Riser is large diameter pipe which, when drilling from a floating rig such
as a semisubmersible or drillship, connects the rig to the well on the ocean
floor. Therefore, the riser string, which consists of sections approximately 75
feet in length connected together, may extend to as much as 10,000 feet. Shaffer
purchases the blank pipe, manufactures and attaches connectors to each section,
and completes it with the attachment of related components.

     Shaffer sells motion compensation equipment under the registered trademark
Rucker(R). Motion compensation equipment stabilizes the bit on the bottom of the
hole, increasing drilling effectiveness of floating offshore rigs by
compensating for wave and wind action. Shaffer also manufactures tensioners
which provide continuous reliable axial tension to the marine riser pipe and
guide lines on floating drilling rigs, tension leg platforms and jack-up rigs.
An important product extension in 1996 was the Riser Recoil System, which
provides a safe disconnect when the floating rig encounters an unanticipated
need to leave location.

                                                                               7
<PAGE>
 
     Shaffer also manufactures and sells flowline devices, primarily Best(TM)
chokes, used in the production phase of the oil and gas industry. These chokes
are designed for both topside-platform and subsea production, for both standard
service and sulfur (H2S) service. Prior to 1993, these chokes were manufactured
and sold by Varco BJ.

     Sales of spare and replacement parts, and the repair and reconditioning of
used equipment constitute a significant part of Shaffer's revenue.

Rigtech

     The Rigtech Division designs, sells and rents solids control equipment and
fluid handling systems. Solids control equipment removes cuttings ("solids")
from the drilling fluid so that it may be recirculated, and fluid handling
systems automate the process of handling drilling fluids on a drilling rig.
Rigtech products are generally subcontracted to third parties for manufacturing.


     In the drilling operation, mud is pumped down the drill pipe and exits
through nozzles in the drill bit. The mud acts as a lubricant to the drill bit,
as a pressure equalizer and as a vehicle which carries the drilled solids back
to the surface. Shale shakers are the principal solids control machines used to
clean the cuttings from the mud, enabling it to be reused. The VSM 100 is
designed to pass large volumes of mud over fine mesh screens to extract as many
of the cuttings from the mud, thus minimizing the use of the other solids
removal equipment before the mud is recirculated. Other equipment that may be
employed to remove solids are the VSM 200 mud cleaner and de-sander and de-
silter hydrocyclones. During 1997 Rigtech introduced the VSM 300, a new
generation shale shaker designed to operate more efficiently in a wider variety
of geologic conditions. In 1998, 77 units were sold.

     The Rigtech fluid handling systems include the AMS 2000 mud chemical
handling system, which is designed to handle, store and mix mud chemicals. The
mud chemicals are provided to the rig in "big-bags" which are placed in a hopper
fitted with a vibrating mechanism. A computer controlled valve in the base of
the bag is used to discharge the chemical powder to the mud mixer at the desired
rate. The AMS 2000 eliminates the manual handling of large sacks of powdered
chemicals, improving efficiency and reducing exposure to a potentially hazardous
work environment.

     The AMS 1000 automated mud system is a computer controlled system which
oversees and controls the entire mud management. The aim of the system is to
release manpower from manual operations while continuously monitoring the
process to ensure that it is performing properly. During 1998 Rigtech delivered
three AMS 1000 systems.

     Rigtech equipment and systems are designed to minimize the cost of drilling
through lowering mud costs and improving operational efficiency, while at the
same time reducing the labor requirement and improving the safety of the
drilling operation.


Research and New Product Development

     Varco believes that it is a leader in the development of new technology and
equipment to enhance the safety and productivity of the drilling process, and
that its sales and earnings have been dependent, in part, upon the successful
introduction of new or improved products. Varco's significant product
developments have included the safety spinning wrench, the torque wrench, the
spring slip, pneumatically operated casing elevators and spiders, the Automated
Roughneck, the Top Drive Drilling System, the Pipe Handling Machine, the Pipe
Racking System, the TOTAL system and the V-ICIS control system. At December 31,
1998, the Company employed 372 persons on its engineering and design staffs who
were principally engaged in research and development. Total expenditures for
research and development were $34.6 million in 1998, $21.1 million in 1997 and
$14.3 million in 1996.

                                                                               8
<PAGE>
 
     As of December 31, 1998, the Company held 110 United States patents and had
6 patent applications pending. Expiration dates of such patents range from 1999
to 2015. As of such date the Company also had  189 foreign patents and 17 patent
applications pending relating to inventions covered by the United States
patents. The preceding include patent rights received in connection with the BJ
Machinery, Martin-Decker, TOTCO and Shaffer acquisitions. There are no
assurances that patents will be granted in response to pending applications.

     Although the Company believes that its patents and applications have value,
competitive products with different designs have been successfully developed and
marketed by others. The Company considers the quality and timely delivery of its
products, the service it provides to its customers and the technical knowledge
and skills of its personnel to be more important than its patents in its ability
to compete. While the Company stresses the importance of its research and
development programs, the expense and market uncertainties associated with the
development and successful introduction of new products are such that there can
be no assurance that the Company will realize future revenues from new products.

Acquisitions


     On November 30, 1994 the Company acquired all of the outstanding shares of
Rig Technology Limited ("Rigtech"), a company incorporated in Scotland, for a
cost of approximately $8,954,000.  Rigtech provides equipment and systems used
in the handling, mixing, transport and conditioning of drilling fluids and
operates as the Company's Rigtech Division.

International Operations

     The Company's products are sold for use in approximately 96 countries by
United States customers operating in the United States and abroad, as well as by
foreign customers such as privately-owned corporations and national oil
companies. The Company includes as an international sale any sale where the
product is designated for use other than in the United States. Revenues from
products sold for use outside the United States accounted for approximately 54%,
56% and 67% of the Company's total revenues for the years ended December 31,
1998, 1997, and 1996, respectively. For further information regarding the
Company's worldwide operations and international sales and rentals, see Note j
of Notes to Consolidated Financial Statements.

     The Company's international operations are subject to the usual risks of
changes in international conditions such as changes in governmental policies
affecting the oil industry (e.g., environmental regulations or the
nationalization of the operations of the Company's customers). Most
international sales are payable in United States dollars.

     The Company has a policy prohibiting the payment of any bribe, kickback or
similar gratuity to any person in order to facilitate the sale of the Company's
products or to secure favorable action by a government official. The Company
believes that this policy does not impede its competitive position in the sale
of its products abroad.

Sales and Distribution

     To facilitate the distribution of its drilling equipment and pressure
control products, the Company maintains domestic sales and service facilities in
California, Louisiana, Oklahoma, Texas and Wyoming. The rental of drilling rig
instrumentation requires local availability of equipment, transportation of the
equipment to the rig site and installation by qualified personnel. To service
this market, the Company maintains M/D Totco sales and service facilities in 11
states, including those mentioned above, as well as 3 locations in Canada.
Internationally, the Company maintains offices in Abu Dhabi, Brazil, China,
Holland, Moscow, Norway, Scotland, Singapore and Venezuela. The Company employs
independent agents in 

                                                                               9
<PAGE>
 
Mexico, South America, Europe, the Middle East, the Far East and Asia, the South
Pacific and in parts of the United States.

     The Company's customers include private and government-owned oil companies,
drilling contractors, drilling rig manufacturers, rental tool companies, and
supply companies which supply oilfield products to the end users of the
Company's products.

     Drilling systems, such as the Automated Roughneck, Top Drive Drilling
System and pipe racking systems and pressure control and motion compensation
equipment, represent significant capital expenditures and are usually sold
directly to an oil company, drilling contractor or rig builder. Other drilling
equipment products may be sold through supply stores or directly to government-
owned oil companies or drilling contractors.


     During 1998 sales to two customers were $122,010,000 and $100,304,000,
respectively. During 1996 sales to one customer amounted to $45,228,000. There
were no sales to a single customer in 1997 in excess of 10% of total sales.

Backlog

     Sales of the Company's products are made on the basis of written purchase
orders or contracts and, consistent with industry practice, by telex, letter or
oral commitment later confirmed by a written order. In accordance with industry
practice, orders and commitments generally can be cancelled by customers at any
time. However, the Company is generally entitled to cancellation fees for
expenses and costs incurred prior to the cancellation of orders. In addition,
orders and commitments are sometimes modified before or during manufacture of
the products.

     The backlog of unshipped orders was approximately as follows on the dates
indicated:

     The Company expects that substantially all of the backlog will be shipped
by December 31, 1999.  At December 31, 1998 the Company had received $95.8
million in customer cash deposits related to orders included in backlog.

Competition

     The products of the Company are sold in highly-competitive markets and its
sales and earnings can be affected by competitive actions such as price changes,
new product development or improved availability and delivery. The Company
competes with a large number of companies, some of which are larger than the
Company and have greater resources and more extensive and diversified
operations.

     Varco's principal competitor with respect to most Varco Systems products is
Maritime Hydraulics A/S, a division of Acker Maritime A/S, a Norwegian company.
Other competitors with respect to the Top Drive Drilling System include
National-Oilwell Inc., A/S Hydralift, another Norwegian company which acquired
the rights to the product previously marketed by ACB offshore, a French company,
and Tesco 

                                                                              10
<PAGE>
 
Corporation, a Canadian company, that competes principally in the land Top Drive
market against Varco Systems' TDS-9S, TDS-10S and TDS-11S. Since its
introduction in 1982 and as of December 31, 1998, Varco had sold and delivered
over 620 Top Drive Drilling Systems, and the Company believes that its
competitors had sold and delivered less than 300 systems during the same time
period.

     Varco's most significant domestic competitors with respect to oil tools
include Phoenix Energy Services, a subsidiary of National-Oilwell Inc., DenCon
Oil Tools and Weatherford International, Inc. In foreign markets Varco
experiences competition from most of its domestic competitors and from foreign
companies as well.

     M/D Totco competes, in the domestic rental market, with the Swaco
Geolograph Division of Smith International, Inc., Petron Industries Inc. and
Adair Supply Inc. In domestic product sales, the competition consists of Wagner
International Inc., Atlas Company and a number of smaller regional companies. In
the international market it competes with these same companies along with such
foreign competitors as Hitec A/S, a Norwegian company.

     Shaffer competes, in the BOP and related controls market, with Cooper
Cameron Corporation, Hydril Company, a privately held company, and Stewart and
Stevenson Services, Inc. Shaffer's principal competitors with respect to motion
compensation equipment are Maritime Hydraulics A/S and A/S Hydralift.

     Rigtech competes in the solids control equipment market principally with
Derrick Manufacturing Inc. and Brandt/EPI, a division of Tuboscope Vetco
International Corporation.

     Although accurate industry figures are not available, the Company believes
that it has a substantial share of the market for most of its equipment and
instrumentation products.

Manufacturing and Raw Materials

     The manufacturing processes for the Company's drilling and pressure control
equipment products generally consist of machining, welding and fabrication, heat
treating, assembly of manufactured and purchased components, and testing. The
Company's drilling and pressure control equipment products are manufactured
primarily from alloy steel, and the availability of alloy steel castings,
forgings, purchased components and bar stock is critical to the production and
timing of shipments. The Company believes that there are currently adequate
sources of supply for alloy steel castings, forgings, purchased components and
bar stock. The primary manufacturing processes associated with instrumentation
and solids control products are fabrication, machining, assembly of manufactured
and purchased components, and testing. The Company believes that adequate
sources of supply exist for all such purchased components.

     Rigtech products are generally subcontracted to third parties for
manufacturing.  The Company believes that an adequate number of subcontractors
exist for the manufacture of Rigtech products.

Employees

     At December 31, 1998 the Company had a total of 2,951 employees (of which
155 were temporary employees). Of such employees, 821 employees were engaged in
sales and marketing, 372 employees were engaged in engineering and design, 153
employees were engaged in administrative or clerical capacities, and 1,605 were
engaged in manufacturing. The Company considers its relations with its employees
to be excellent and has never suffered a work stoppage or interruption due to a
labor dispute.

                                                                              11

ITEM 2.  PROPERTIES

     The Company's principal manufacturing facilities are located in Orange,
California (the "Orange Facility"), Etten-Leur, The Netherlands (the "Etten-Leur
Facility"), Cedar Park, Texas (the "Cedar Park Facility") and Houston.  The
Orange Facility and the Etten-Leur Facility are used primarily for manufacturing
the Company's drilling equipment; the Cedar Park Facility manufactures primarily
instrumentation products; and the Houston Facilities are used for manufacturing
pressure control, motion compensation and drilling equipment and flow line
devices.  Rigtech products are generally subcontracted to third parties for
manufacturing.

     The Orange Facility occupies approximately nine acres in Orange County,
California which are leased under a long-term lease. The Orange Facility
includes three manufacturing/warehouse buildings comprising a total of
approximately 160,000 square feet and a four-story high-rise facility with
automatic storage and retrieval capabilities. The Orange Facility is currently
leased, and the lessors include certain officers, shareholders, and directors of
the Company and affiliated trusts. During 1997 the Varco Systems Division leased
an additional 19,000 square foot manufacturing building located nearby for a
term of five years. The Orange Facility is the primary manufacturing location
for the Varco Systems Division, and the Company estimates that based upon direct
labor hours and a two shift operation, utilization of this facility was in
excess of a two shift operation for 1998 and 1997 as compared to approximately
95% of capacity in 1996.

     The Etten-Leur Facility consists of approximately 73,000 square feet of
manufacturing and warehousing space and approximately 12,900 square feet of
office space on approximately six acres of land. This facility is the primary
manufacturing location for the Varco BJ Division, and the Company estimates that
based upon direct labor hours and a two shift operation, utilization of this
facility was in excess of a two shift operation for 1998 as compared to near
capacity in 1997 and 1996.

     The M/D Totco products are manufactured at the Cedar Park Facility. The
Company leased this facility from Cooper Industries, Inc. until 1995 when the
Company purchased this facility for approximately $3.6 million. The Cedar Park
Facility consists of approximately 200,000 square feet of manufacturing and
warehousing space and approximately 33,000 square feet of office space located
on approximately 40 acres. The Company estimates that based upon direct labor
hours and a two shift operation, utilization of this facility was in excess of a
two shift operation in 1998 and 1997 and approximately 95% of capacity during
1996.

     The Shaffer Division's products are principally manufactured at the
"Shaffer Facility", which consists of approximately 286,000 square feet of
manufacturing and warehousing space and approximately 77,000 square feet of
office space located on approximately 34 acres located in Houston, Texas. In
addition, certain products of the Varco BJ Division are manufactured at this
facility. The Shaffer facility has been operated by the Company since the
acquisition of Shaffer in 1992. The Company estimates that based upon direct
labor hours and a two shift operation, utilization of this facility for 1997 and
1996 was in excess of a two shift operation as compared to 80% in 1995. In
February 1997, Shaffer purchased all of the assets of a Houston machine shop
operation and simultaneously entered into a five-year lease for the related
80,000 square foot manufacturing facility. Shaffer began operation of the
facility in March 1997. During 1997 Shaffer further expanded its manufacturing
space by acquiring additional satellite facilities in 

                                                                              13

the Houston area. At the end of 1997 Shaffer leased the above 80,000 square foot
facility plus four additional satellite facilities ranging in size from 8,000
square feet to 33,000 square feet (together with the Shaffer Facility, the
"Houston Facilities.") Two of the satellite facilities have been listed for
sale.


     An additional manufacturing facility located in Houston (the "Houston BJ
Facility") was closed during the fourth quarter of 1992 and activities
previously performed at that plant have been moved to other Company locations,
principally the Shaffer Facility. The Houston BJ Facility, which consists of
approximately 135,000 square feet of manufacturing and office space, and the
32.2 acres of land on which it is located are owned by the Company. This
facility has been listed for sale.

     The Drilling Systems Division's administration and the Company's executive
offices are located in Orange, California adjacent to the Orange Facility. They
comprise approximately 36,000 square feet of office space and are leased from
certain officers, shareholders and directors of the Company, affiliated trusts
and other lessors.

     The Company owns sales and service facilities in Oklahoma, Wyoming,
Scotland and Singapore and leases approximately 22 such facilities throughout
the United States in addition to facilities in Brazil, Canada, China, Mexico and
Venezuela.

Operations on pages 24 through 28 of the Registrant's Annual Report to
Shareholders for the year ended December 31, 1998, is hereby incorporated by
reference.


ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

       The Company is exposed to certain market risks which are inherent in the
Company's financial instruments and which arise from transactions entered into
in the normal course of business.  The Company does not considered these risks
significant, and the Company does not enter into derivative financial instrument
transactions to offset these risks.

     Borrowings under the Company's revolving credit facility do not give rise
to significant interest rate risks because these borrowings have a variable
interest rate. The Company is subject to interest rate risk on its fixed
interest rate debt. Generally, the fair market value of debt with a fixed
interest rate will increase as interest rates fall, and the fair market value
will decrease as interest rates rise. Fixed interest rate borrowings have not
been significant during the three years ended December 31, 1998.

(d)  Schedules

The Report of Independent Auditors and the schedule listed in the Index to
Financial Statements and Schedules (Item 14(a)) are filed as part of this Annual
Report on Form 10-K.

                         REPORT OF INDEPENDENT AUDITORS

Shareholders and Board of Directors
Varco International, Inc.

We have audited the accompanying consolidated balance sheets of Varco
International, Inc. and subsidiaries as of December 31, 1998 and 1997, and the
related consolidated statements of income, shareholders' equity and cash flows
for each of the three years in the period ended December 31, 1998. Our audits
also included the financial statement schedule listed in the Index at Item
14(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 based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Varco
International, Inc. and subsidiaries at December 31, 1998 and 1997, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1998, in conformity with 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.

                AMENDED AND RESTATED ARTICLES OF INCORPORATION
                                      OF
                           VARCO INTERNATIONAL, INC.


         The undersigned, Richard A. Kertson and Donald L. Stichler, do hereby 
certify that:

         1.    They are the duly elected and acting Vice President-Finance and 
Secretary, respectively, of Varco International, Inc., a California corporation 
(the "Corporation").

         2.    The Amended and Restated Articles of Incorporation of the 
Corporation are amended by revising Article Three thereof to read in its 
entirety as follows:

                              "Authorized Shares

         Three:      This corporation is authorized to issue two classes of
                     shares designated respectively "Common Stock" and
                     "Preferred Stock," referred to herein as Common Stock or
                     Common Shares and Preferred Stock or Preferred Shares,
                     respectively. The number of shares of Common Stock is
                     one hundred twenty million (120,000,000) and the number
                     of shares of Preferred Stock is ten million
                     (10,000,000). The Preferred Shares may be issued from
                     time to time in one or more series. The Board of
                     Directors is authorized to fix the number of shares of
                     any series of Preferred Shares and to determine the
                     designation of any such series. The Board of Directors
                     is also authorized to determine or alter the rights,
                     preferences, privileges, and restrictions granted to or
                     imposed upon any wholly unissued series of Preferred
                     Shares and, within the limits and restrictions stated in
                     any resolution or resolutions of the Board of Directors
                     originally fixing the number of shares constituting any
                     series, to increase or decrease (but not below the
                     number of shares of such series then outstanding) the
                     number of shares of any such series subsequent to the
                     issue of shares of that series."

         3.    The foregoing amendment has been duly approved by the Board of 
Directors of the Corporation.

                                     
<PAGE>
 
     4.  The foregoing amendment has been duly approved by the required vote of
shareholders of the Corporation in accordance with Section 902 of the California
Corporations Code; the total number of outstanding shares of each class entitled
to vote with respect to the foregoing amendment was 64,324,335 shares of Common
Stock and there were no outstanding shares of Preferred Stock. The number of
shares of Common Stock voting in favor of the foregoing amendment equaled or
exceeded the vote required, such required vote being a majority of the
outstanding shares of Common Stock.

     We further declare under penalty of perjury that the matters set forth in 
the foregoing Certificate of Amendment are true and correct of our own 
knowledge.

     Executed at Orange, California on May 19, 1998.

                           VARCO INTERNATIONAL, INC.


  The undersigned, Richard A. Kertson and Donald L. Stichler do hereby certify:

  1.  That they are the duly elected and acting Vice President-Finance and
Secretary, respectively, of Varco International, Inc., a California corporation
(the "Corporation").

  2.  That pursuant to the authority conferred upon the Board of Directors by
the Amended and Restated Articles of Incorporation of the said Corporation, the
said Board of Directors on November 6, 1997 adopted the following resolutions
creating a series of 80,000 shares of Preferred Stock designated as "Series A
Participating Preferred Stock":

  "RESOLVED, that pursuant to the authority vested in the Board of Directors of
the Corporation by the Amended and Restated Articles of Incorporation, the Board
of Directors does hereby provide for the creation of a series of Preferred Stock
of the Corporation, to be designated "Series A Participating Preferred Stock,"
initially consisting of 80,000 shares, and does hereby fix and herein state and
express such designations, powers, preferences and relative and other special
rights and the qualifications, limitations and restrictions of such series of
Preferred Stock as follows:

  Section 1.  Designation and Amount.  The shares of such series of Preferred
Stock shall be designated as "Series A Participating Preferred Stock," and the
number of shares constituting such series shall be 80,000.  Such number of
shares may be increased or decreased by resolution of the Board of Directors;
provided, however, that no decrease shall reduce the number of shares of Series
A  Participating Preferred Stock to less than the number of shares then issued
and outstanding plus the number of shares issuable upon exercise of outstanding
rights, options or warrants or upon conversion of outstanding securities issued
by the Corporation.

  Section 2.  Dividends and Distributions.

          (a)  Subject to the prior and superior right of the holders of any
shares of any series of Preferred Stock ranking prior and superior to the shares
of Series A Participating Preferred Stock with respect to dividends, the holders
of shares of Series A Participating Preferred Stock shall be entitled to receive
when, as and if declared by the Board of Directors out of funds legally
available for the purpose, quarterly dividends payable in cash on the last day
of January, April, July and October in each year (each such date being referred
to herein as a "Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment 

                                       1
<PAGE>
 
Date after the first issuance of a share or fraction of a share of Series A
Participating Preferred Stock, in an amount per share (rounded to the nearest
cent) equal to the then applicable Adjustment Number (as hereinafter defined)
times the aggregate per share amount of all cash dividends, and the then
applicable Adjustment Number times the aggregate per share amount (payable in
kind) of all non-cash dividends or other distributions other than a dividend
payable in shares of Common Stock or a subdivision of the outstanding shares of
Common Stock (by reclassification or otherwise), declared on the Common Stock of
the Corporation (the "Common Stock") since the immediately preceding Quarterly
Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment
Date, since the first issuance of any share or fraction of a share of Series A
Participating Preferred Stock. The "Adjustment Number" shall initially be 1,000.
In the event the Corporation shall at any time after November 6, 1997 (the
"Rights Dividend Declaration Date") (i) declare and pay any dividend on Common
Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common
Stock, or (iii) combine the outstanding Common Stock into a smaller number of
shares, then in each such case the Adjustment Number in effect immediately prior
to such event shall be adjusted by multiplying such Adjustment Number by a
fraction, the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

          (b)  The Corporation shall declare a dividend or distribution on the
Series A Participating Preferred Stock as provided in paragraph (a) above after
it declares a dividend or distribution on the Common Stock (other than a
dividend payable in shares of Common Stock).

          (c)  Dividends shall begin to accrue on outstanding shares of Series A
Participating Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares of Series A Participating Preferred
Stock, unless the date of issue of such shares is prior to the record date for
the first Quarterly Dividend Payment Date, in which case dividends on such
shares shall begin to accrue from the date of issue of such shares, or unless
the date of issue is a Quarterly Dividend Payment Date or is a date after the
record date for the determination of holders of shares of Series A Participating
Preferred Stock entitled to receive a quarterly dividend and before such
Quarterly Dividend Payment Date, in either of which events such dividends shall
begin to accrue from such Quarterly Dividend Payment Date. Accrued but unpaid
dividends shall not bear interest. Dividends paid on the shares of Series A
Participating Preferred Stock in an amount less than the total amount of such
dividends at the time accrued and payable on such shares shall be allocated pro
rata on a share-by-share basis among all such shares at the time outstanding.
The Board of Directors may fix a record date for the determination of holders of
shares of Series A Participating Preferred Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be no more
than 60 days prior to the date fixed for the payment thereof.

  Section 3.  Voting Rights.  The holders of shares of Series A Participating
Preferred Stock shall have the following voting rights:

                                       2
<PAGE>
 
          (a)  Each share of Series A Participating Preferred Stock shall
entitle the holder thereof to a number of votes equal to the then Applicable
Adjustment Number on all matters submitted to a vote of the shareholders of the
Corporation.

          (b)  Except as otherwise provided herein or required by law, the
holders of shares of Series A Participating Preferred Stock and the holders of
shares of Common Stock shall vote together as one class on all matters submitted
to a vote of shareholders of the Corporation.

          (c)  Except as otherwise provided herein or required by law, holders
of Series A Participating Preferred Stock shall have no special voting rights
and their consent shall not be required (except to the extent they are entitled
to vote with holders of Common Stock as set forth herein) for taking any
corporate action.

  Section 4.  Certain Restrictions.

          (a)  The Corporation shall not declare any dividend on, make any
distribution on, or redeem or purchase or otherwise acquire for consideration,
any shares of Common Stock after the first issuance of a share or fraction of a
share of Series A Participating Preferred Stock unless concurrently therewith it
shall declare a dividend on the Series A Participating Preferred Stock as
required by Section 2 hereof.

          (b)  Whenever quarterly dividends or other dividends or distributions
payable on the Series A Participating Preferred Stock as provided in Section 2
are in arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Series A Participating
Preferred Stock outstanding shall have been paid in full, the Corporation shall
not

               (i)    declare or pay dividends on, make any other distributions
on, or redeem or purchase or otherwise acquire for consideration any shares of
stock ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Participating Preferred Stock;

               (ii)   declare or pay dividends on, or make any other
distributions on, any shares of stock ranking on a parity (either as to
dividends or upon liquidation, dissolution or winding up) with Series A
Participating Preferred Stock, except dividends paid ratably on the Series A
Participating Preferred Stock and all such parity stock on which dividends are
payable or in arrears in proportion to the total amounts to which the holders of
all such shares are then entitled;

               (iii)  redeem or purchase or otherwise acquire for consideration
shares of any stock ranking on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Series A Participating
Preferred Stock, provided that the Corporation may at any time redeem, purchase
or otherwise acquire shares of any such parity stock in exchange 

                                       3
<PAGE>
 
for shares of any stock of the Corporation ranking junior (either as to
dividends or upon dissolution, liquidation or winding up) to the Series A
Participating Preferred Stock;

               (iv)   redeem or purchase or otherwise acquire for consideration
any shares of Series A Participating Preferred Stock, or any shares of stock
ranking on a parity (either as to dividends or upon liquidation, dissolution or
winding up) with the Series A Participating Preferred Stock, except in
accordance with a purchase offer made in writing or by publication (as
determined by the Board of Directors) to all holders of the Series A
Participating Preferred Stock or to such holders and holders of any shares
ranking on a parity therewith upon such terms as the Board of Directors, after
consideration of the respective annual dividend rates and other relative rights
and preferences of the respective series and classes, shall determine in good
faith will result in fair and equitable treatment among the respective series or
classes.

          (c)  The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under paragraph (a) of
this Section 4, purchase or otherwise acquire such shares at such time and in
such manner.

     Section 5.  Reacquired Shares.  Any shares of Series A Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and cancelled promptly after the acquisition
thereof.  All such shares shall upon their retirement become authorized but
unissued shares of Preferred Stock and may be reissued as part of a new series
of Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to the conditions and restrictions on issuance set forth
herein and in the Amended and Restated Articles of Incorporation, as then
amended.

     Section 6.  Liquidation, Dissolution or Winding Up.

          (a)  Upon any liquidation, dissolution or winding up of the
Corporation, voluntary or otherwise, no distribution shall be made to the
holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Participating Preferred
Stock unless, prior thereto, the holders of shares of Series A Participating
Preferred Stock shall have received an amount per share equal to accrued and
unpaid dividends and distributions thereon, whether or not declared, to the date
of such payment, plus an amount equal to the greater of (1) $1,000, provided
that in the event the Corporation does not have sufficient assets, after payment
of its liabilities and distribution to holders of Preferred Stock ranking prior
to the Series A Participating Preferred Stock, available to permit payment in
full of the $1,000 per share amount, the amount required to be paid under this
Section 6(a)(1) shall, subject to Section 6(b) hereof, equal the value of the
amount of available assets divided by the number of outstanding shares of Series
A Participating Preferred Stock or (2) the then applicable Adjustment Number
times the aggregate per share amount to be distributed to the holders of Common
Stock (the greater of (1) or (2), the "Series A Liquidation Preference").

                                       4
<PAGE>
 
          (b)  In the event, however, that there are not sufficient assets
available to permit payment in full of the Series A Liquidation Preference and
the liquidation preferences of all other series of Preferred Stock, if any,
which rank on a parity with the Series A Participating Preferred Stock in
respect thereof, then the assets available for such distribution shall be
distributed ratably to the holders of the Series A Participating Preferred Stock
and the holders of such parity shares in proportion to their respective
liquidation preferences.

          (c)  Neither the merger or consolidation of the Corporation into or
with another corporation nor the merger or consolidation of any other
corporation into or with the Corporation shall be deemed to be a liquidation,
dissolution or winding up of the Corporation within the meaning of this Section
6.

     Section 7.  Consolidation, Merger, etc.  In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Participating Preferred Stock shall at the same time be similarly
exchanged or changed in an amount per share equal to the then applicable
Adjustment Number times the aggregate amount of stock, securities, cash and/or
any other property (payable in kind), as the case may be, into which or for
which each share of Common Stock is changed or exchanged.

     Section 8.  No Redemption.  The shares of Series A Participating Preferred
Stock shall not be redeemable.

     Section 9.  Ranking.  The Series A Participating Preferred Stock shall rank
junior to all other series of the Corporation's Preferred Stock as to the
payment of dividends and the distribution of assets upon liquidation,
dissolution or winding up, unless the terms of any such series shall provide
otherwise.

     Section 10. Amendment.  At any time that any shares or fractions of shares
of Series A Participating Preferred Stock are outstanding, the Amended and
Restated Articles of Incorporation of the Corporation shall not be further
amended in any manner which would materially alter or change the powers,
preferences or special rights of the Series A Participating Preferred Stock so
as to affect them adversely without the affirmative vote of the holders of a
majority of the outstanding shares of Series A Participating Preferred Stock,
voting separately as a class.

     Section 11. Fractional Shares.  Series A Participating Preferred Stock may
be issued in fractions of a share which shall entitle the holder, in proportion
to such holder's fractional shares, to exercise voting rights, receive
dividends, participate in distributions and to have the benefit of all other
rights of holders of Series A Participating Preferred Stock.

     Section 12.  Consent for Certain Repurchases of Common Stock.  Each holder
of outstanding shares of Series A Participating Preferred Stock shall be deemed
to have consented, 

                                       5
<PAGE>
 
for the purposes of Sections 502, 503 and 506 of the California General
Corporation Law, to distributions made by the Corporation in connection with the
repurchase of shares of Common Stock of the Corporation issued to or held by
employees, consultants, officers and directors of the Corporation upon
termination of their employment or services with the Corporation pursuant to
agreements providing for the rights of repurchase between the Corporation and
such persons.

     RESOLVED FURTHER, that the President or any Vice President and the
Secretary or any Assistant Secretary of this corporation be, and they hereby
are, authorized and directed to prepare and file a Certificate of Determination
of Rights, Preferences and Privileges in accordance with the foregoing
resolution and the provisions of California law and to take such actions as they
may deem necessary or appropriate to carry out the intent of the foregoing
resolution."

     3.   That the number of shares constituting the Series A Participating
Preferred Stock is 80,000.  Such number of shares may be increased or decreased
by resolution of the Board of Directors; provided, however, that no decrease
shall reduce the number of shares of Series A Participating Preferred Stock to
less than the number of shares then issued and outstanding plus the number of
shares issuable upon exercise of outstanding rights, options or warrants or upon
conversion of outstanding securities issued by the Corporation.

     4.   None of the shares of the Series A Participating Preferred Stock has
been issued.

     We further declare under penalty of perjury that the matters set forth in
the foregoing Certificate of Determination are true and correct of our own
knowledge.

                           VARCO INTERNATIONAL, INC.


  The undersigned, Richard A. Kertson and Donald L. Stichler do hereby certify
that:

  1.  They are the duly elected and acting Vice President-Finance and Secretary,
respectively, of Varco International, Inc., a California corporation (the
"Corporation").

  2.  The Certificate of Determination of Rights, Preferences and Privileges of
Series A Participating Preferred Stock being corrected was filed with the
Secretary of State on November 6, 1997.

  3.  Section 2(a) of the Certificate of Determination of Rights, Preferences
and Privileges of Series A Participating Preferred Stock is corrected to read in
its entirety as follows:

        "Section 2.  Dividends and Distributions.

        (a)  Subject to the prior and superior right of the holders of any
     shares of any series of Preferred Stock ranking prior and superior to the
     shares of Series A Participating Preferred Stock with respect to dividends,
     the holders of shares of Series A Participating Preferred Stock shall be
     entitled to receive when, as and if declared by the Board of Directors out
     of funds legally available for the purpose, quarterly dividends payable in
     cash on the last day of January, April, July and October in each year (each
     such date being referred to herein as a "Quarterly Dividend Payment Date"),
     commencing on the first Quarterly Dividend Payment Date after the first
     issuance of a share or fraction of a share of Series A Participating
     Preferred Stock, in an amount per share (rounded to the nearest cent) equal
     to the then applicable Adjustment Number (as hereinafter defined) times the
     aggregate per share amount of all cash dividends, and the then applicable
     Adjustment Number times the aggregate per share amount (payable in kind) of
     all non-cash dividends or other distributions other than a dividend payable
     in shares of Common Stock or a subdivision of the outstanding shares of
     Common Stock (by reclassification or otherwise), declared on the Common
     Stock of the 
<PAGE>
 
     Corporation (the "Common Stock") since the immediately preceding Quarterly
     Dividend Payment Date, or, with respect to the first Quarterly Dividend
     Payment Date, since the first issuance of any share or fraction of a share
     of Series A Participating Preferred Stock. The "Adjustment Number" shall
     initially be 1,000. In the event the Corporation shall at any time after
     November 6, 1997 (the "Rights Dividend Declaration Date") (i) declare and
     pay any dividend on Common Stock payable in shares of Common Stock, (ii)
     subdivide the outstanding Common Stock, or (iii) combine the outstanding
     Common Stock into a smaller number of shares, then in each such case the
     Adjustment Number in effect immediately prior to such event shall be
     adjusted by multiplying such Adjustment Number by a fraction, the numerator
     of which is the number of shares of Common Stock outstanding immediately
     after such event and the denominator of which is the number of shares of

To:    Compensation Committee
From:  Dick Kertson
Date:  February 3, 1999
Re:    Proposed Financial Criteria--1999 Management Incentive
       Bonus Plan

The general structure of the Plan and the financial performance criteria
employed remain generally unchanged from recent years.  The cash bonus payout is
expressed as a percentage of annual salary and is a function of Salary Grade and
the financial performance level achieved.  Financial performance is measured by
profitability (Net Income at the total Company level and Operating Income at the
Division level) and return on investment (Economic Value Added or "EVA" at both
the total Company and Division level).  To earn the bonus points associated with
a given level of financial performance, both the minimum profit and return on
                                        ----                                 
investment associated with that level must be achieved.

In 1998, achieving the Annual Financial Plan equated to 9 Bonus Points on a
scale of 2-15 for all Divisions and the total Company.  Reflecting the disparate
performance among Divisions and the overall Company shortfall to Plan, only the
Drilling Systems Division was above Plan, realizing 14 Bonus Points.  The Varco
BJ Oil Tools Division was at the 6 point level and the total Company's
performance was at 5 points.  Neither the MD/Totco, Shaffer, or Rigtech Divisons
reached the minimum financial performance necessary to qualify for a bonus.

A summary of the key elements of the proposed 1999 Management Incentive Bonus
Plan follows:

 .  Achieving the "Financial Plan" (the Original Annual Financial Plan as revised
   in the January quarterly update) would result in 7 Bonus Points for the total
   Company, on a scale of 2-15. The Drilling Systems and Oil Tools Divisions
   would each realize 10 points for reaching the Financial Plan; and M/D Totco,
   Shaffer and Rigtech would each achieve 6 points at their Financial Plan
   performance. The disparity between target points reflects the fact that the
   1999 Financial Plan for Drilling Systems and Oil Tools is at 
<PAGE>
 
   or above 1997 performance, and for the other three Divisions and the total
   Company the planned 1999 performance is below that of 1997.

 .  The bonus percentages (bonus/salary ratio) associated with each Bonus Point
   level have been revised for all Salary Grades. The ratio which equates to the
   75th percentile in the salary survey data is set at 11 Bonus Points; the
   average ratio is set at 7 Bonus Points..


In addition to the cash bonus, it is proposed that each participant in the Plan
be once again eligible for a Stock Bonus, based on total Company performance.
As has been the case for several years, the Stock Bonus would be paid in Varco
stock having a value equal to 1/3 of the bonus amount due a participant based on
his/her Salary Grade and the total Company financial performance level achieved.

For Division Presidents, 25% of the cash bonus amount is based upon the points
attributable to total Company performance.

Again in 1998 we propose that Corporate Officers have the opportunity to
increase their cash bonus by 50%, or decrease it by 33%, depending on the
performance of Varco Stock relative to a group of 9 peer companies.
Specifically, if the year-to-year increase in the price of Varco Stock (as
measured by the average of the last 5 trading days of 1999 divided by the
average for the last 5 trading days of 1998) is among the top 3 of 10 companies,
Corporate Officers' cash bonuses would be increased by 50%; if Varco's Stock
price increase is among the bottom 3 of the group such bonuses would be reduced
by 33%.  (Note that this element of the Plan comes into play only during stock
price appreciation).  We believe that this aspect of the bonus program achieved
its objective of focusing increased attention on stock price performance.

The peer group would include:  Baker Hughes, Halliburton, Schlumberger, Smith
International, Cooper Cameron, Tuboscope Vetco, National Oilwell, Weatherford
International, and IRI.

                            Varco achieved record 


                           performance in 1998 and 


                         strengthened its position as 


                          a leading manufacturer of 


                          oil and gas well drilling 


                             equipment worldwide.

                          Although 1999 will benefit 


                      from previously committed orders, 


                     drilling activity has been adversely 


                    affected by lower oil and gas prices. 


                       Once again, our challenge is to 


                        manage successfully through a 


                       downturn while taking advantage 


                         of new market opportunities. 


                    Overall, our strategy remains constant.

           APPEARS HERE]   

      ===================================================================



                 TO OUR SHAREHOLDERS, CUSTOMERS AND EMPLOYEES


For the oil service industry, 1998 was a year of dramatic contrasts. It began on
a high note, with more rigs drilling throughout the world than at any time in
this decade. The offshore rig fleet was effectively fully employed, with
utilization above 95 per cent, and commitments for the construction of new
offshore rigs were being announced regularly. Despite some weakening in oil
prices beginning in November of 1997, the mood of the industry was decidedly
buoyant. However, by the end of 1998, inflation-adjusted oil prices plunged to
their lowest level in decades, worldwide drilling activity declined to record
lows and offshore rig utilization and dayrates were falling rapidly. The mood
turned somber, as oil service companies made a strategic about-face, from a
focus on growth and expansion to one of retrenchment.

     Varco has not been immune to any of these influences. Therefore, it is
important to review our 1998 performance against the backdrop of these overall
industry conditions.

                               Financial Results

Both Revenues and Net Income for 1998 were the highest in the Company's 91-year
history. Revenues of $741.0 million were up 36 per cent from $545.8 million in
the prior year and more than double the $368.4 million of two years ago. Net
Income was $60.3 million, $.92 per share, including a pre-tax charge of $8.5
million, $.09 per share, for severance and other expenses anticipated during
1999 as we reduce our cost structure to conform with current market conditions.
Excluding this charge, 1998 income was 32 per cent above the $49.9 million, $.76
per share, earned in 1997.

     Order bookings for 1998 were $757.4 million before cancellations of $118.0
million, versus $820.9 million in 1997 and $478.5 million in 1996. Through the
first half of the year incoming orders maintained a rate somewhat above the 1997
level, before declining in each of the final two quarters. The cancellations,
which occurred primarily in the second half of the year, virtually all relate to
orders for equipping new offshore rigs. Although nearly all of the rigs under
construction have long-term contracts with oil companies, those that do not have
been the source of most of the cancellations.

     Although the December 31, 1998 backlog of $367.4 million is below the
$462.9 million at the end of 1997, it is still the second highest year-end total
in the Company's history. Most of this backlog is due to be delivered during the
next twelve months. Accordingly, it will be toward the end of 1999 or early 2000
before the full impact of the industry slowdown is reflected in our financial
results.

     Meanwhile, our financial condition remains strong. The year-end 1998

reflects debt of just $9.9 million and cash and cash equivalents of $29.1
million, providing a solid financial base during this period of market
uncertainty.

     Although 1998 was another year of substantial revenue and profit growth,
and represented outstanding financial performance by virtually all measures, any
feeling of satisfaction is tempered by the expectation that current market
conditions make the road ahead much more difficult.

                         Market Conditions and Outlook

As indicated previously, weak oil prices are responsible for the deteriorating
market conditions experienced during 1998. After averaging more than $20 per
barrel during each of the previous two years, oil prices averaged approximately
$14.40 for all of 1998 and $13.50 for the fourth quarter. As a result, in its
annual Survey of Worldwide Exploration and Production Expenditures, Salomon
Smith Barney predicts that 1999 spending will be down 11 per cent from 1998
levels. That represents the first forecasted year-to-year decline since 1993,
and the largest projected drop since 1986.

     Although our order backlog provides a buffer against the full effect of
these reductions during 1999, until oil prices recover and oil companies regain
sufficient confidence to increase spending we expect that revenues will be
significantly below those of 1998.

                                   Strategies

With lower oil prices, oil companies will be even more tenacious in their drive
to reduce drilling costs. That focus plays into our historical strength and
reinforces our continuing efforts to develop products and technologies that help
achieve that goal. By being successful in that endeavor we can reduce the
negative effect of the market conditions.

     A primary challenge for us in 1999 is to deliver, install and support the
Varco equipment already committed to offshore rigs under construction. These
rigs will be the most advanced, automated rigs in the world, and by
demonstrating superior performance they can enhance our opportunity to retrofit
older rigs with this type of equipment.

     The realities of our market require that we reduce our cost structure to a
level consistent with the sustaining level of business. Accomplishing that while
developing new products and ensuring the success of the new advanced technology
rigs will require a high level of dedication and skill on the part of our
people. We are confident in our ability to achieve these goals.

     We appreciate your continued support.

Interview with George Boyadjieff
Chairman, President and Chief Executive Officer:

[PHOTO OF GEORGE BOYADJIEFF APPEARS HERE]

Q: 1998 was a year in which record performance was achieved by the Company in a
number of areas. What do you consider to be the Company's most significant
accomplishments over that period of time?

A: The most significant was successfully expanding our capabilities and capacity
in order to meet the growth in customer demand. We were able to capture a
significant share of the equipment orders for new rigs, and firmly establish
ourselves as the major supplier of drilling equipment in the world. We did this
without incurring additional debt, which provides the Company with a very strong
balance sheet going forward.

Q: What were some of your disappointments?

A: We were not able to leverage our revenue growth into improved profit margins.
Although we anticipated that some inefficiencies were bound to occur with our
dramatic growth in employment, which increased by more than seventy per cent
over an eighteen-month period, we still expected that we could improve our
margins. However, we were not able to make that happen. And, of course the
declining industry conditions resulting from low oil prices were both a surprise
and a disappointment.

Q: Speaking of oil prices, what has been the impact on Varco of the low oil
prices which have prevailed for the past 12 months or so?

A: There was not much impact until the second half of the year when we began to
see a reduced incoming order rate, particularly orders for equipment related to
new rig construction. We have also seen some order cancellations where new rig
building programs were terminated. The primary impact on 1998 results was in the
M/D Totco Division's rental business, which is directly related to the North
American rig count. We saw a significant quarter-to-quarter revenue decline
there.

Q: What are the most significant challenges the Company faces in 1999?

A: One challenge for 1999 is to focus on product development, particularly those
products that can significantly reduce drilling costs, so that we bring to the
market new products which generate revenues to help offset the expected market
decline. At the same time, we must deliver the equipment for the rigs currently
under construction in a timely manner and ensure that the equipment performs
well when it begins operation.

                            [GRAPHIC APPEARS HERE]

Q: What are the Company's strategies for dealing with the current market
environment?

A: We will stick with the strategies that have made us successful so far. Again,
the primary strategy is to continue to introduce new products which reduce
drilling costs. Those are the products that can be sold best in a tough market.
Of course, we will downsize and reduce costs as appropriate to the market
conditions that prevail.

Q: Where do you see opportunities for product development and the introduction
of new technology?

A: The key opportunity is in upgrading existing drilling rigs with automation
for improved efficiency, and integrating information technology with automation
by using computer-based data collection and analysis to directly control more of
the rig functions. This has been done in a number of industries and has resulted
in improved efficiency and safety. The drilling industry is no different. Time
and again it has been proven that experience can improve a process--but only to
a point. Beyond that, the ability to collect data instantaneously, analyze the
data and respond appropriately to the conditions it suggests, can produce
dramatic improvement. We are only beginning to see this potential with respect
to the drilling process.

Q: Are you satisfied with the Company's position today?

A: As anyone at Varco will tell you, I am, by nature, never satisfied. I do
believe that Varco has never been better positioned than it is today. At the
same time, we need to increase the intensity of our product development efforts
to generate more true "break through" products which dramatically reduce
drilling costs. The Top Drive Drilling System has done this and I believe that
automated pipe racking can too. Those are the kinds of products that enable us
to be successful in a difficult market.

Q: When do you expect the current market to turn around?

A: I don't know, and to be honest I don't spend a lot of time worrying about it.
Nobody has demonstrated an ability to consistently predict oil prices. I believe
that Varco's success depends upon our ability to create our own future--to get
the best possible results in whatever market environment exists. That's our goal
and that's something we can control.

[GRAPHIC APPEARS HERE]        Operations Review

================================================================================

                                Industry Trends

Conditions in the oil service industry changed dramatically over the course of
1998. Following two years of improvement, the year began with industry activity
demonstrating continued strength. Although there was weakness in oil prices, it
was generally expected to be mild and short-lived, and the consensus outlook was
for continued growth. However, by year-end oil prices plunged to unforeseen
levels, and the industry's orientation switched from growth to contraction.

     Oil prices averaged $18.40, $22.10, and $20.60 per barrel for the years
1995-1997, respectively, and natural gas prices averaged $1.50, $2.50 and $2.50
per thousand cubic feet over the same periods. These commodity prices produced
strong cash flow for the major and independent oil companies of the world, and
they responded with increased investment in exploration and production ("E &
P"). According to Salomon Smith Barney's Annual Survey of Worldwide Oil and Gas
Exploration and Production Expenditures, the increases were 9 per cent, 15 per
cent and 19 per cent, respectively, for the 1995-1997 period. This investment
produced a period of solid growth for the oil service industry.

     A number of factors converged in late 1997 to precipitate a decline in oil
prices. The economic crisis in Asia produced a weakening of demand from an area
that had been responsible for much of the growth in recent years. Warmer than
normal winter weather throughout the world compounded the problem. Meanwhile,
the OPEC members elected to increase their output quotas in November of 1997,
and the higher E & P spending increased the supply of oil flowing from the
non-OPEC world. The combination of these factors was more severe than originally
anticipated, and oil prices, on an inflation-adjusted basis, declined to 25-year
lows by late 1998 and early 1999.

     In this environment, Salomon Smith Barney estimates that growth in E & P
spending slowed to 5 per cent for 1998, and indications are that any increase
occurred early in the year and that the rate of spending over the second half of
the year was well below 1997 levels.

     In December of 1997 there were 2,318 rigs drilling in the world and the
offshore rig fleet was at 95 per cent utilization--effectively fully employed.
By December of 1998 the number of rigs drilling had declined by 32 per cent to
1,566 and offshore rig utilization was 83 per cent.

     The Salomon Smith Barney survey for 1999 projects that worldwide E & P
spending will be down 11 per cent from 1998. The survey further indicates that
spending plans are based on an average oil price of $14.67, which is above the
level existing during early 1999, indicating the potential for further spending
reductions if prices do not improve over the course of the year.

     All indications are for a difficult period ahead for the oil service
industry. On a more positive 

                                     no 9.

note, however, most industry analysts believe that the gap between supply and
demand across all segments of the industry is narrower than during previous
periods of low oil prices and curtailed activity. Reduced E & P spending will
ultimately result in a sufficient reduction in oil supply to provide a basis for
recovery.


                               Varco International

Varco operates through five independent but complementary Divisions, each
providing a portion of the equipment and systems which are integral to the
drilling process. When sold as replacement equipment or as a typical upgrade to
an existing rig, the products of each Division are usually purchased
independently. However, when equipping a new rig or providing a major retrofit
of an existing offshore rig, Varco products and systems are frequently sold as a
"package" which often involves some level of physical and electronic
integration.

     Although Varco products are used both offshore and onshore, the cost and
complexity of offshore drilling requires a substantially greater investment in
drilling equipment. Additionally, drilling in extremely deep water from a
floating rig, such as a semi-submersible or drillship, requires significantly
more equipment than a jackup rig or fixed platform. For example, the value of
the equipment which Varco could potentially supply to a deep water rig is
approximately $50 million, as compared to approximately $19 million for a harsh
environment jackup or platform rig. By comparison, a typical new land rig would
create a potential of approximately $3 million of revenue for Varco.

     While Varco's five Divisions are all influenced primarily by general
industry and market conditions, each is also uniquely affected by factors
specific to its primary markets and products.


Varco Systems designs and manufactures systems and equipment for rotating and
handling the various types and sizes of pipe used on a drilling rig. Its
products are designed to make the drilling process more productive and safer. At
the time of their introduction, Varco Systems' products have typically
represented innovative new methods for performing critical drilling functions.

The principal products of the Varco Systems Division are the Top Drive Drilling
System ("TDS") and pipe handling systems. Introduced in 1982, the TDS is
recognized as a more productive means of drilling an oil or gas well than the
traditional rotary table. Although its initial applications were primarily
offshore and high-cost land drilling where the initial investment could be more
quickly returned, more recently the TDS concept has gained acceptance in
conventional land drilling.

Sales of the TDS are primarily influenced by the construction of new offshore
rigs, retrofitting of land rigs and existing offshore rigs, and replacement of
previously sold units with newer, upgraded models. To a lesser extent, revenue
is derived from the rental of TDS units.

                        Varco BJ manufactures a complete
                   line of drilling rig tools and equipment,
                   including pipe handling tools and hoisting
                             and rotary equipment.

     Pipe handling systems are automated or semi-automated devices which provide
both vertical and horizontal pipe handling. Vertical pipe racking systems are
used to move sections of pipe between the storage ("racking") area on the rig
floor and the well center, and to provide the spinning and torquing functions
necessary to couple and uncouple sections of pipe. Horizontal pipe racking
systems are used to handle various sizes and types of pipe while stored on the
pipe deck of an offshore rig, transport pipe sections up to the rig floor, and
raise them to a vertical position from which they are passed to a vertical
racking system. 

     Automated pipe handling systems were introduced by Varco in 1987 and most
units sold to date have been for new offshore rigs. Although new rig
construction has been the predominant market, systems more specifically directed
to the retrofit market are currently under development.

     Revenues of the Varco Systems Division were $266.8 million in 1998, up 61
per cent from $165.5 million in 1997 and 127 per cent from $117.7 million in
1996. This Revenue growth is primarily attributable to automated pipe handling
systems and related equipment for new offshore rigs.

Varco BJ manufactures a complete line of conventional drilling rig tools and
equipment. It has evolved from the combination of the original Varco products
with several complementary and competitive product lines acquired over the past
10 years. Examples of Varco BJ's products include: elevators, devices which hold
pipe while it is being lifted from, or lowered into, the bore hole; slips, which
grip pipe and hold it in suspension while in the well; the spinning wrench, a
pneumatic or hydraulic powered device used to screw together and unscrew
threaded pipe connections; manual tongs, used to make up or break out
connections; and casing elevators and spiders, gripping devices used to hold
heavy sections of casing while being lowered into the well. Many of these
products were original Varco innovations at the time of their introduction, and
Varco BJ is regarded as the industry leader in providing quality and
reliability.

     As the Varco product line has moved toward automation and the elimination
of personnel from the rig floor, Varco BJ's products have evolved to facilitate
this result by providing mechanization and remote activation to tools previously
operated manually. While products with these capabilities would be considered
mandatory when used in conjunction with a fully automated pipe handling system,
they provide sufficient safety and efficiency benefits that they are also sold
independently for upgrading existing rigs.

     Revenues of the Varco BJ Division totaled $96.0 million in 1998, 39 per
cent above the $68.9 million in 1997 and 78 per cent above the $53.8 million in
1996. The year-to-year increase in Revenues in 1998 is attributable to generally
higher worldwide drilling activity; an emphasis on the replacement and upgrading
of older equipment on existing rigs; and the increase in offshore rig
construction.

M/D TOTCO designs and sells computer-based drilling information and control
systems, as well as conventional drilling rig instrumentation. Instrumentation
systems, at a minimum, consist of sensors which monitor and measure various data
relevant to drilling operations and an output or display device. Their basic
purpose is to provide the driller and other rig personnel with the information
necessary to operate the drilling rig. In recent years, the drilling industry
has moved from basic instrumentation toward computer-based information and
control systems designed to make the drilling process safer and more efficient.

     Leading that transition, M/D Totco introduced the TOTAL system in 1991. It
consists of sensors, a Data Acquisition Unit ("DAQ") or computer processor,
graphical output devices, and data storage and transmission capability. In its
basic form, TOTAL collects data and presents it to the driller in an
individually configurable graphic or digital format, while also storing it for
subsequent analysis. More advanced capabilities include software applications
that analyze and interpret the data to assist rig personnel in optimizing
drilling operations and anticipating and avoiding potential problems.

     In 1997 M/D Totco introduced the Varco Integrated Control and Information
System ("V-ICIS"), a computer-based system which combines the physical control
of all of Varco's automated equipment, and potentially that of third parties,
into a common, user-friendly system which also incorporates the analytical
capabilities of the TOTAL system. Orders for 16 systems have been received and
the initial four systems were delivered in 1998.

     Like Varco's other Divisions, M/D Totco's Revenues are influenced by the
overall level of drilling activity, rig upgrade and refurbishment, and new rig
construction. In general, the nature of its products have caused the first two
of these elements to have a relatively greater impact on M/D Totco than on Varco
as a whole. In particular, the rental business, which has typically constituted
40 to 45 per cent of its Revenues, is directly influenced by the level of
drilling activity, especially in North America. As a result of the declining rig
count, M/D Totco's rental Revenues were $30.9 million in 1998, versus $37.6
million in 1997. Overall Revenues were $94.6 million in 1998, as compared to
$90.6 million in 1997, and $62.2 million in 1996.

Shaffer manufactures and sells pressure control and motion compensation
equipment. Pressure control equipment includes blowout preventers ("BOP's") and
the control systems that enable their remote activation; and riser, large
diameter pipe used to connect a floating offshore rig (semi-submersible or
drillship) to the ocean floor. Motion compensation equipment is used on floating
rigs to offset the effect of wind and wave action on the drilling process.

     Shaffer has experienced dramatic growth over the past three years as a
result of the increase in deepwater drilling (in excess of 3,000 feet) and the
demand for rigs having such capability. Early in

that period Shaffer benefited from rig owners upgrading the water depth capacity
of existing rigs, and later from the building of new deepwater rigs. The impact
on Shaffer of either is substantial, as a new deepwater rig requires equipment
of the type supplied by Shaffer valued in excess of $30 million, and a major
upgrade offers a potential of approximately half that figure. In the ten or so
years preceding 1995 there was almost no new investment in rigs of this type;
consequently, the recent increase in demand has caused Shaffer's Revenues to
increase dramatically.

     Revenues were $256.2 million in 1998, versus $206.5 million in 1997 and
$123.8 million in 1996. This increase in Revenues is directly attributable to
the growth of deepwater drilling and the resultant upgrading and construction of
rigs capable of such drilling.


Rigtech designs and sells solids control equipment and fluid handling systems.
During drilling operations drilling fluid ("mud") is circulated through the well
bore to contain formation pressure, lubricate the drill bit, and return cuttings
to the surface. Rigtech's revenues result primarily from the sale of solids
removal equipment, primarily shale shakers, which remove cuttings ("solids")
from the drilling fluid so that it may be recirculated, and from the sale of
spare and expendable parts for such equipment.

     Rigtech has also developed equipment and systems which automate the process
of handling drilling fluids on a drilling rig ("Automated Mud System" or "AMS").
Included are devices which monitor and control the mixing of drilling fluids,
the dispensing of chemical additives, and the movement of fluids between mixing
hoppers, the mud pits (from which it is pumped into the bore hole), and back
through the cleaning process. During 1998 Rigtech delivered three such systems,
the first since the prototype was introduced in 1993.

     Rigtech's Revenues were $21.3 million in 1998, versus $13.4 million in 1997
and $9.4 million in 1996. The Revenue increase in 1998 is primarily attributable
to the AMS.

     Rigtech, based in Aberdeen, Scotland, was a privately held company prior to
its acquisition by Varco in 1994. Although it enjoys a very substantial share of
the North Sea market, Rigtech has a relatively small share of the overall
worldwide solids control market. Through a combination of product development
and geographic expansion, it is Varco's goal to expand considerably that market
position.

                                Financial Review

1998 Revenues of $741.0 million were the highest in the Company's history, 36
per cent above the $545.8 million for 1997 and more than double the $368.4
million recorded in 1996. Net Income was $60.3 million, including the special
charge described below. Excluding this charge, Net Income of $66.0 million, was
up 32 per cent from $49.9 million in 1997 and 169 per cent from $24.5 million in
1996. The growth of the past two years was driven by two primary factors: (1) a
trend toward drilling

in deeper water which led to the upgrading of existing offshore rigs and the
construction of new rigs and (2) the relatively high level of offshore drilling
activity which prevailed for most of the period.

     Incoming orders for 1998 were $757.4 million (excluding cancellations of
$118.0 million), following totals of $820.9 million and $478.5 million,
respectively, for the preceding two years. Peak order rates were reached during
the second half of 1997 and the first half of 1998, following which the
weakening market began to have a significant impact. As a result of the market
conditions and declining order rate, the Company recorded a special charge of
$8.5 million in the fourth quarter of 1998 for severance and other expenses
expected to be incurred during 1999 as the cost base is reduced.

     Following a sharp increase in 1997, Operating Profit margins (Earnings
Before Interest and Taxes, or "EBIT", as a percent of Revenues) were 12.5 per
cent in 1998, as compared to 14.7 per cent in the prior year and 11.4 per cent
in 1996. The year-to-year decline is attributable to a 3.7 per cent lower Gross
Margin and a 0.8 per cent increase in Research and Development expense as a per
cent of Revenue, which were only partially offset by a decrease in Selling,
General and Administrative expenses in relation to Revenues. The lower Gross
Margin results from two primary factors, of roughly equal magnitude: (1)
approximately $40 million of Revenue from three new products at low Gross
Margins; and (2) higher manufacturing costs and inefficiencies related to the
increase in volume and employment over the past two years. While the initial
units of a new product typically result in high manufacturing costs and below
average Gross Margins, the impact in 1998 was particularly significant due to
unusually high new product Revenues.

     Cash Flow Return on Investment (EBIT plus Depreciation, Amortization and
special charge) as a per cent of Average Net Investment (Shareholders' Equity
plus Debt less Cash), considered by the Company to be a very meaningful measure
of overall financial performance, remained very favorable in 1998 at 41 per
cent, unchanged from the prior year and well above the 27 per cent achieved in
1996.

     The Company's balance sheet remains strong, as cash and cash equivalents of
$29.1 million exceeded total Debt of $9.9 million at December 31, 1998 and
Shareholders' Equity was $319.4 million.

     Although the increase in profitability was below our expectations given the
substantial Revenue growth, by virtually all measures our 1998 financial
performance was very good. Importantly, the rapid growth we have experienced
over the past two years has been financed without incurring debt. A strong
balance sheet will serve us well in this period of uncertainty.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS


                                   Background

The business of the Company depends primarily upon the level of worldwide
drilling activity, particularly offshore drilling activity. The level of
drilling activity can be influenced by numerous factors, including the prices of
oil and gas, economic and political conditions, finding and development costs of
oil companies, development of alternative energy sources, availability of
equipment and materials, availability of new onshore and offshore acreage or
concessions, and new and continued governmental regulations regarding
environmental protection, taxation, price controls and product allocations.

     Beginning in late 1997 oil and gas prices began to weaken, particularly the
price of oil. The weakness continued through 1998 as the price of oil averaged
approximately $14.40 a barrel and ended the year between $11 and $12 a barrel.
Natural gas prices averaged approximately $2.04 per thousand cubic feet for 1998
but declined to an average of approximately $1.74 for December. The price of oil
averaged approximately $20.60 and $22.10 a barrel for 1997 and 1996,
respectively. The price of natural gas averaged approximately $2.50 per thousand
cubic feet for each of 1997 and 1996. During 1996 and 1997, these commodity
prices resulted in improved profits and cash flows for oil companies. Due in
part to these stronger financial results, oil companies increased exploration
and production expenditures, leading to increased drilling activity in 1996 and
1997. Conversely, the declining commodity prices during 1998 have led to lower
cash flows for the oil companies and a reduction in exploration and production
expenditures, leading to declining drilling activity. Commodity prices have
remained low for the early part of 1999, further negatively impacting the level
of worldwide drilling activity.

     Rig counts, as reported by industry sources, for each of the past three
years are summarized in the following table:

                                                     1998     1997     1996 
       --------------------------------------------------------------------
       Approximate Average Annual Rig Count:                                

       Worldwide average rig count                  1,843    2,126    1,836 
        United States & Canada average rig count    1,088    1,317    1,043 
        International average rig count               755      809      793 
       Approximate average number of                                        
        offshore rigs under contract                  555      606      550 
       
In 1998, overall drilling activity, as reflected by the average number of rigs
drilling worldwide, fell to its 1996 level after growing by approximately 16% in
1997. Drilling activity declined throughout 1998, ending the year with the
December rig count averaging approximately 1,566. Significant in its impact on
the Company during 1997 and 1996 was increased worldwide utilization of offshore
rigs (rigs under contract as a percent of available rigs), which was driven both
by increased demand and by a continually shrinking supply of available offshore
rigs. Utilization rates were 94% and 90% for the years 1997 and 1996,
respectively, and each of these rates was higher than any year since 1982. The
higher utilization was accompanied by increasing dayrates and longer contract
periods, particularly among the "premium" offshore rigs. This resulted in
increased cash flow for the Company's major customers, the drilling contractors,
and the announcement of plans to increase the mobile offshore rig fleet. Both
the average number of offshore rigs under contract and the utilization rates
began to decline in the second quarter of 1998 and have continued to decline
throughout the year. In December of 1998, the approximate average number of
offshore rigs under contract was 510 and the utilization rate was approximately
83%.

                             RESULTS OF OPERATIONS

The Company operates principally in the oil and gas well drilling equipment
segment of the oilfield service industry. Set forth below are the annual orders
for the Company's five Divisions which serve this segment.

          ===========================================================          

Orders declined $181.5 million, 22%, in 1998 as compared to 1997. This decline
is primarily the result of the reduction in, and cancellation of, orders
associated with upgrading and construction of offshore drilling rigs. The
cancellations in 1998 were primarily due to customers terminating the
construction of certain offshore drilling rigs and cancelling the related
equipment orders. Of the total cancellations, approximately $67.1 million were
incurred by Shaffer and $35.6 million by Varco Systems with the balance
distributed among the remaining Divisions. New orders were also negatively
impacted at all Divisions by the decline in overall drilling activity. M/D
Totco's 1998 increase in orders was due to its new drilling rig control system,
"V-ICIS," which was introduced in 1997.

     During 1998, the quarterly order rate declined throughout the year. The
first quarter order rate was $299.6 million (less $13.0 million in
cancellations) and the fourth quarter order rate was $117.5 million (less $54.4
million in cancellations).

     The higher level of orders in 1997 as compared to both 1998 and 1996 is
primarily due to orders associated with upgrading and construction of offshore
drilling rigs, particularly floating rigs that are capable of drilling in water
depths exceeding 3,000 feet. Each such rig creates significant potential for the
high dollar value products provided by the Shaffer and Varco Systems Divisions.
During 1997 Shaffer secured several orders to provide pressure control, motion
compensation and related equipment, and Varco Systems obtained several orders to
provide vertical and horizontal pipe handling systems and Top Drive Drilling
Systems ("TDS's") to these rigs. The increase in orders for the Varco BJ and M/D
Totco Divisions also resulted, in part, from the offshore rig upgrades and new
construction. Rigtech's 1997 increase is primarily due to increased orders of
"Automated Mud Systems" for such rigs.

     In addition to the construction and upgrading of offshore drilling rigs, in
1997 the Company benefited from increased sales of spare and replacement parts
and service related to the increase in worldwide drilling activity. The Company
estimates that approximately 20% to 25% of its order growth in 1997 is
attributable to such increases.














     Set forth below are the annual revenues for the Company's five Divisions.

The Company's sales and rentals increased by $190.0 million, 35% in 1998 as
compared to 1997, with the Shaffer and Varco Systems Divisions accounting for
$151.0 million of this increase. Approximately 85% of the increase at each of
these Divisions is due to the delivery of equipment for offshore rig upgrades
and construction and the remainder is due to increased sales of spare and
replacement parts. Substantially all of the increases at the other Divisions are
due to the delivery of equipment for offshore rig upgrades and construction.

     The Company's sales and rentals increased by $177.9 million, 48% in 1997 as
compared to 1996, with the Shaffer and Varco Systems Divisions accounting for
$130.5 million of this increase. Approximately 70% of the increase at each of
these Divisions is due to the delivery of equipment for offshore rig upgrades
and construction and the remainder is due to the overall drilling activity
increase. M/D Totco and Varco BJ revenues increased $28.4 and $15.1 million,
respectively. Approximately 55% of these increases are related to the overall
drilling activity increase with the balance due to upgrades and rig
construction.

     In early 1999, the price of oil remained in the $11 to $12 a barrel range
and drilling activity continued to decline. If the price of oil doesn't increase
significantly, management believes that new orders for its products are likely
to decline below the fourth quarter rate of $117.5 million and negatively impact
future revenues. The effect on 1999 revenues will be somewhat lessened by the
shipment of the December 31, 1998 backlog.

     The Company's backlog of unshipped orders was $367.4 million at December
31, 1998, as compared to $462.9 million at December 31, 1997, and $186.9 million
at December 31, 1996. The Company expects that substantially all of the backlog
will be shipped by December 31, 1999. At December 31, 1998, the Company had
received $95.8 million in customer cash deposits related to orders included in
backlog. In accordance with industry practice, orders and commitments generally
are cancellable by customers at any time. As a result of low oil prices and the
downturn in drilling activity, the Company anticipates that it will experience
additional cancellations. While the Company cannot predict the potential dollar
value of any such cancellations, it expects such cancellations will be
substantially less than the amount experienced in 1998.

     The increase in other income for 1998 as compared to prior years is
attributable to cancellation fees received for expenses and costs incurred prior
to the cancellation of orders.

     Gross margins (net sales and rental income less costs of sales and rental
income) as a percentage of net sales and rental income for the Company were
32.5% for 1998, 36.2% for 1997 and 34.3% for 1996. 1998 gross margins were
negatively impacted by high initial costs and retrofit costs on newer products
at Shaffer, M/D Totco and Rigtech; higher manufacturing costs and increased
manufacturing inefficiencies at all Divisions related to the increase in volume;
and by the decline in rental revenue which carries a higher gross margin than
other revenues. New products and retrofit costs accounted for approximately 2.3%
of the 3.7% gross margin decline from 1997; higher manufacturing costs and
inefficiencies accounted for approximately 1.0%; and lower rental income
accounted for the balance. The higher 1997 margins as compared to 1996 were a
result of improved margins at Varco Systems, Varco BJ and M/D Totco. These
improvements favorably impacted consolidated margins by 3.2% as their combined
margins improved from 38.9% in 1996 to 43.9% in 1997. Price increases accounted
for approximately two-thirds of this improvement with the remainder attributable
to the favorable Dutch Guilder exchange rate lowering dollar cost at Varco BJ's
Netherlands manufacturing facility and to cost reductions. This improvement was
partially offset by the larger percentage increase in Shaffer's revenue and by
lower margins at the Shaffer Division. Shaffer's products carry lower gross
margins (due principally to price competition) than the combined gross margins
of the other Divisions. In addition, Shaffer's 1997 margins were negatively
impacted by high initial costs on some of its newer products.

     The Company believes that new product development is significant to the
future growth of the Company. Research and development expenses were $34.6
million, $21.1 million and $14.3 million for the years 1998, 1997 and 1996
respectively, and represented 4.7%, 3.9% and 3.9% of revenue, respectively, for
those years. The Company expects that research and development expenses will
continue at approximately 4.0% to 5.0% of revenue in 1999.

     Selling, general and administrative expenses were $109.1 million in 1998
(14.7% of revenues) as compared to $96.4 million in 1997 (17.7% of revenues) and
$70.9 million (19.2% of revenues) in 1996. The increases in 1998 and 1997 as
compared to 1996 resulted primarily from increases in employment related costs.
The Company expects

                                     [ $ ]

that total selling, general and administrative expenses will decline in the
future, commensurate with the anticipated revenue levels. It is further expected
that the relation of these expenses to revenue will be above the 1998 rate of
14.7%.

     At December 31, 1998, overall Company employment was 2,951 (including 155
temporary employees) as compared to 2,852 (including 415 temporary employees) at
December 31, 1997 and 1,936 (including 220 temporary employees) at December 31,
1996. 

     During the fourth quarter of 1998, the Company recognized an $8.5 million
special charge consisting of the following: severance cost for 1,100 employees
of $6.1 million; a non-cash write-off of rental equipment of $1.5 million and an
allowance for abandoned leases and other obligations of $900 thousand. The
Company has adopted a plan to restructure all of its Divisions' operations
consistent with the current and expected lower market conditions. The Company
spent $422 thousand of the $7.0 million of cash charges in 1998 and expects to
spend substantially all of the remaining cash charges in 1999.

     The Company's effective income tax rate was 33.8% in 1998 as compared to
35.0% in 1997 and 35.6% in 1996. The lower effective income tax rate in 1998 as
compared to 1997 and 1996 resulted from the elimination in 1998 of the Company's
valuation allowance on deferred tax assets. The Company now believes that it is
more likely than not that all of its deferred tax assets will be realized.


                        Liquidity and Capital Resources

At December 31, 1998 the Company had cash and cash equivalents of $29.1 million
as compared to $39.8 million at December 31, 1997. During 1998, the Company
generated $31.2 million from operations, invested $35.3 million in property,
plant and equipment and paid down long-term debt by $10.0 million.

     In July 1992, the Company sold $50.0 million aggregate principal amount of
its 8.95% Senior Notes Due June 30, 1999 (the "Senior Notes") to a group of ten
institutional investors pursuant to a Note Agreement dated as of July 1, 1992
(the "Note Agreement"). The remaining $10.0 million principal balance of the
Senior Notes is payable on June 30, 1999.

     On June 27, 1997 the Company entered into a seven-year unsecured revolving
credit agreement with three banks (the "Credit Agreement"). The Credit Agreement
provides for a credit facility of $65.0 million, inclusive of a $20.0 million
letter of credit sub-facility. The maximum available under the Credit Agreement
is reduced in equal quarterly amounts over the last four years of the Credit
Agreement. Proceeds from the initial advances were used to repay borrowings
under a previous credit agreement and for the June 30, 1997 principal and
interest payment on the Senior Notes. At December 31, 1998, there were no
advances outstanding and $4.2 million in letters of credit outstanding under
this facility.

     Both the Note Agreement and the Credit Agreement restrict the payment of
dividends (other than dividends payable solely in shares of Common Stock) on,
and repurchases of, Common Stock. Under the terms of the Credit Agreement, which
is generally the more restrictive of these, the amount available for the payment
of dividends on, and repurchases of, Common Stock is limited to $5.0 million
plus 25% of the Company's consolidated net income arising after June 30, 1997,
computed on a cumulative basis. At December 31, 1998, the amount available for
dividends and repurchases under the Credit Agreement was $28.0 million.

     On November 6, 1997, the Board of Directors of the Company declared a
two-for-one stock split of its Common Stock, payable on December 4, 1997 to
shareholders of record at the close of business on November 20, 1997.

     Working capital was $176.3 million at December 31, 1998 compared to $137.5
million at December 31, 1997. The Company's current ratio has increased from 1.7
to 1.0 at December 31, 1997 to 1.8 to 1.0 at December 31, 1998. The increase in
working capital and current ratio is primarily due to the higher level of
receivables and inventory to support the Company's higher revenue levels in
1998. At December 31, 1998, the Company had no long-term debt.

     Capital expenditures were $35.3 million in 1998 and $35.1 million in 1997.
These capital expenditures were primarily for the purchase of additional machine
tools to increase manufacturing capacity. The Company expects to reduce its
capital expenditures in 1999 to less than $20 million. The Company believes that
its December 31, 1998 cash and cash equivalents and its credit facility will be
sufficient to meet its capital expenditures, cash portion of the special charge,
operating cash needs, and the principal payment on the Senior Notes in 1999.

                              Year 2000 Compliance

The Year 2000 Issue is the result of computer programs that use only two digits
to identify a year rather than four. If not corrected, computer applications
could fail or create erroneous results before, during and after the Year 2000.

         The Company is continuing to assess the impact that the Year 2000 Issue
may have on its information technology ("IT") systems and its operations and has
identified the following four key areas of its business that may be affected: 

Products The Company has developed detailed testing procedures for each of its
products that have a date reference. Compliance testing of the Company's
products, in accordance with these procedures, is approximately 90% complete
with the testing of all products expected to be completed by March 31, 1999. The
most extensive testing is in the M/D Totco Division, which develops software for
control systems and drilling applications. Based upon the evaluation and testing
completed, the Company believes that its currently supported products, as
opposed to discontinued and obsolete products, are Year 2000 compliant. The
Company has mailed to its customers a list of compliant products and has advised
customers which products needed to be upgraded or replaced for Year 2000
compliance.

Internal Business Systems The Year 2000 Issue could affect the systems,
transaction processing, computer applications and devices used by the Company to
operate and monitor all major aspects of its business, including financial
systems, customer services, materials requirement planning, master production
scheduling, networks and telecommunications systems. The Company has completed
its assessment phase and believes that it has identified substantially all of
the major systems, software applications and related equipment used in
connection with its internal operations that must be modified or upgraded in
order to minimize the possibility of a material disruption to its business. The
Company is currently in the remediation phase of modifying and upgrading all
affected systems and expects to complete this phase by the beginning of the
third quarter of 1999. The Company estimates that it will be Year 2000 compliant
by the end of the third quarter of 1999. However, any unforeseen problems which
occur during the testing phase may adversely affect the Company's Year 2000
readiness.

Third-Party Suppliers and Customers The Company relies directly and indirectly,
on external systems utilized by its suppliers for materials used in the
manufacture of its products. The Company has requested confirmation from its
suppliers of their Year 2000 compliance. The Company has received replies from
approximately 15% of its suppliers. The replies received indicate that Year 2000
compliance will be achieved. However, there can be no assurance that suppliers
will resolve all Year 2000 Issues with their systems in a timely manner. Any
failure of third parties to resolve their Year 2000 Issues in a timely manner
could result in the material disruption of the business of the Company. Any such
disruption could have an adverse effect on the Company's operations.

     The Company does not intend to canvas its customers to insure that
customers are Year 2000 compliant. While the Company does not believe that
non-compliance by its customers would significantly impact their ability to
continue their drilling operations and their ability to purchase drilling
equipment, any disruption to the drilling process caused by non-compliance could
negatively impact the Company's revenues.

Facility Systems Facility systems such as manufacturing equipment, heating,
sprinklers, test equipment and security systems may also be affected by the Year
2000 Issue. The Company has commenced an assessment of the impact of all such
systems on its facilities and does not anticipate any material impact on the
Company's operations.

     The Company does not separately track internal cost incurred on the Year
2000 Issue. The Company has estimated that approximately 15% to 20% of its IT
personnel's time is spent on the Year 2000 Issue. As of December 31, 1998,
approximately $500 thousand have been accrued or paid to third parties relating
to this issue. The Company has estimated that approximately $1.0 to $2.0 million
will be paid in 1999 to third parties for software, hardware and consultation.
The Company recognizes the need for developing contingency plans to address the
Year 2000 Issues that may pose a significant risk to its on-going operations.
Such plans could include the implementation of manual procedures to compensate
for system deficiencies. During the remediation phase of the internal business
systems, the Company will be evaluating potential failures and will attempt to
develop responses in a timely manner. However, there can be no assurance that
any contingency plans evaluated and potentially implemented by the Company would
be adequate to meet the Company's needs without materially impacting its
operations, that any such plan would be successful or that the Company's results
of operations would not be materially and adversely affected by the delays and
inefficiencies inherent in conducting operations in an alternative manner.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


                                     [ a ]

                   Summary of significant accounting policies

Description of Business  Varco International, Inc. and its subsidiaries (the
"Company") are engaged in the design, manufacture, sale and rental of tools,
equipment and instrumentation used primarily in the worldwide oil and gas well
drilling equipment segment of the oil field service industry. The Company
operates through five Divisions: Varco Systems, whose products include
integrated systems for rotating and handling pipe on a drilling rig; Varco BJ,
whose products include pipe handling tools, hoisting equipment and rotary
equipment; M/D Totco, whose instrumentation products are used in the management
of drilling operations and control of equipment; Shaffer, whose products include
pressure control and motion compensation equipment and flow devices; and
Rigtech, whose products are used in the handling, mixing, transport and
conditioning of drilling fluids.

Principle of Consolidation   The consolidated financial statements include the
accounts of Varco International, Inc. and its wholly-owned subsidiaries. All
material intercompany balances and transactions have been eliminated in
consolidation.

Use of Estimates   The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual amounts could differ from those estimates.

Cash and Cash Equivalents   The Company considers all highly liquid investments
with a maturity of three months or less when purchased to be cash equivalents.

Concentrations of Credit Risk   Substantially all of the Company's accounts
receivable are due from customers in the oil and gas industry, both in the
United States and internationally. The Company performs periodic credit
evaluations of its customers and generally does not require collateral. In
certain circumstances, the Company requires letters of credit to further ensure
credit worthiness.

Inventories   Inventories are stated at the lower of cost or market. The Company
determines the cost of inventories using the last-in, first-out ("LIFO") method.

Rental equipment   Rental equipment is stated at the lower of cost or market,
net of accumulated depreciation of $23,407,000 and $18,261,000 at December 31,
1998 and 1997, respectively. Rental equipment is depreciated over estimated
useful lives ranging from 3 to 7 years. The equipment is generally leased under
short-term arrangements, usually not exceeding 90 days in duration. In 1998, the
Company determined, as a result of market conditions, that certain M/D Totco
rental equipment would not be rentable in the future. Accordingly, a special 
non-cash charge of $1,500,000 was incurred to write-off this rental equipment.

Depreciation   Depreciation is provided using the straight-line method over
estimated useful lives ranging from 3 to 30 years.

Intangible Assets   The excess of cost over net assets of businesses acquired
("goodwill") is amortized on a straight-line basis over periods ranging from 10
to 40 years. The carrying value of goodwill will be reviewed if the facts and
circumstances suggest that it may be impaired. If this review indicates that
goodwill will not be recoverable, as determined based on the undiscounted cash
flows of the entity acquired over the remaining amortization period, the
Company's carrying value of the goodwill will be reduced by the estimated
shortfall of cash flows. Included in Other Assets are other intangible assets
totaling $2,376,000, net of accumulated amortization of $6,626,000 at December
31, 1998, which are being amortized on a straight-line basis over estimated
useful lives ranging from 5 to 17 years.

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. The provision for income taxes is the tax payable or refundable for
the period plus or minus the change during the period in deferred tax assets and
liabilities.

                                     [ $ ]

Impairment of Long-Lived Assets   Impairment losses are recorded on long-lived
assets used in operations when indicators of impairment are present and the
undiscounted cash flows estimated to be generated by those assets are less than
the assets' carrying amount. Long-lived assets expected to be disposed of,
including excess equipment and production facilities held for sale, are stated
at their estimated fair value less cost to sell.

Revenue Recognition   The Company recognizes revenue upon shipment of product,
upon the use of rented equipment and upon the completion of installation work.

Fair Value of Financial Instruments   The carrying amounts of financial
instruments including cash and cash equivalents, accounts receivable and
accounts payable approximated fair value as of December 31, 1998 and 1997
because of the relatively short maturity of these instruments. The carrying
value of debt approximated fair value as of December 31, 1998 and 1997, based
upon quoted market prices for similar debt issues.

Foreign Currency   The Company has determined that the United States dollar is
the functional currency of all its foreign subsidiaries except for Rig
Technology Limited whose functional currency is the British pound sterling.
Accordingly, the financial statements of most foreign operations are remeasured
in terms of the United States dollar and exchange gains and losses are
recognized in operations. The exchange losses in 1998 were $994,000 and the
exchange gains in 1997 and 1996 were $264,000 and $283,000, respectively.
Financial statements of Rig Technology Limited are translated at current rates
of exchange, with gains or losses resulting from translation included in
retained earnings.

Stock Based Compensation   The Company accounts for stock option grants to
employees in accordance with APB Opinion No. 25, "Accounting for Stock Issued to
Employees".

Per Share Data   Basic per share amounts are computed by dividing net income by
the weighted average number of common shares outstanding. Dilutive per share
amounts are computed by dividing net income by the weighted average number of
common shares and dilutive common share equivalents, which consist solely of
converting outstanding stock options, using the treasury method.

Special Charge   During the fourth quarter of 1998, the Company adopted a plan
to restructure all of its Divisions' operations consistent with the current and
expected lower market conditions and recognized an $8,500,000 special charge
consisting of the following: severance for 1,100 employees of $6,100,000; a non-
cash write-off of rental equipment of $1,500,000; and an allowance for abandoned
leases and other obligations of $900,000. The Company spent $422,000 of the cash
provision in 1998 and expects to spend substantially all of the remaining cash
costs in 1999.

Reclassification    Certain amounts in the 1997 and 1996 financial statements
have been reclassified to conform with current year classification.

     =========================================================================

A portion of the Company's inventory is not expected to be sold or used within
one year and, accordingly has been reclassified as Other Assets. The amount of
inventory estimated to exceed one year's usage was $7,500,000 and $3,500,000 at
December 31, 1998 and 1997, respectively.

                                 Long-term debt

Long-term debt consists of notes payable to institutional investors under an
8.95% Senior Note Agreement (the "Note Agreement.") Principal is due in five
equal annual installments which commenced June 30, 1995, and interest is payable
semiannually. The Note Agreement contains restrictive covenants requiring the
maintenance of certain financial ratios, limitations on additional borrowings
and capital expenditures, and restrictions on distribution of cash or other
property. The remaining principal balance of $10 million is payable on June 30,
1999.

     The Company has a seven-year unsecured revolving credit agreement, dated
June 27, 1997, with three banks (the "Credit Agreement"). The Credit Agreement
provides for a credit facility of $65.0 million, inclusive of a $20.0 million
letter of credit sub-facility. The maximum available under the Credit Agreement
is reduced in equal quarterly amounts over the last four years of the Credit
Agreement. Advances under the Credit Agreement bear interest at either a prime
rate minus .25% or a rate based on the Eurodollar Market. The agreement requires
a commitment fee of .25% of the unused portion of the credit facility, restricts
additional borrowings if minimum asset levels are not met and contains
restrictive covenants requiring the maintenance of certain financial ratios,
limitations on additional borrowings and capital expenditures, and restrictions
on distribution of cash or other property. At December 31, 1998, there were no
advances outstanding and $4.2 million in letters of credit outstanding under
this facility.

     Interest paid during 1998, 1997 and 1996 was $1,698,000, $3,664,000 and
$5,470,000, respectively.

                              Shareholders' equity

On November 6, 1997, the Board of Directors of the Company declared a
two-for-one stock split of its Common Stock, payable in the form of a 100% stock
dividend, on December 4, 1997 to shareholders of record at the close of business
on November 20, 1997. Stock options, and all other agreements payable in the
Company's Common Stock, have been adjusted to reflect the split. In addition,
the balance shown as Common Stock has been increased to reflect the split with a
corresponding decrease in additional paid-in capital. All references to number
of shares, except shares authorized, in the consolidated financial statements
and related notes have been adjusted to reflect the stock dividend on a
retroactive basis.

     The Varco 1980 Employee Stock Purchase Plan permits the Company's employees
to purchase Common Stock at a price equal to 85% of its fair market value at the
beginning or end of a six-month plan period. As of December 31, 1998, 2,584,737
shares have been sold under this plan with a maximum of 4,000,000 shares
available for sale under this plan.

     The Varco International, Inc. Stock Bonus Plan (the "Bonus Plan")
authorizes the Compensation Committee of the Board of Directors to award
additional compensation to selected key employees of the Company in the form of
stock awards payable in shares of Common Stock of the Company to a maximum of
2,000,000 shares. Through December 31, 1998, 838,415 shares have been granted
and issued to key employees under the Bonus Plan.

     The Varco International, Inc. 1990 Stock Option Plan permits, and
predecessor plans permitted, the grant of incentive and non-statutory options to
key employees and officers. Options granted under the plans must be not less
than the fair market value of the stock on the date of grant. Options are
exercisable during such periods as determined by the Compensation Committee and
expire not later than ten years from the date of the grant.

     The Varco International, Inc. 1994 Directors' Stock Option Plan provides
for the grant of a 10,000 share stock option on the initial date of election as
a director plus an annual grant of a 10,000 share stock option to each
non-employee director. Options granted under this plan are at the fair market
value of the stock on the date of grant. Options are exercisable for ten years
from the date of the grant unless sooner terminated.

     Stock option activity for the plans was as follows:

In 1996, the Company adopted the disclosure provisions of FASB Statement No. 123
"Accounting for Stock-Based Compensation". As permitted by that standard the
Company continues to follow Accounting Principles Board Opinion No. 25
"Accounting for Stock Issued to Employees" in accounting for its plans.
Accordingly, no compensation expense has been recognized for its stock option
plans and its stock purchase plan. The compensation cost that has been charged
against income for its stock bonus plan was $985,000, $1,549,000 and $569,000
for the years 1998, 1997 and 1996, respectively. Had compensation costs for the
Company's stock option plans and stock purchase plan been determined based upon
fair value at the grant date under these plans consistent with FASB Statement
No. 123 methodology, the Company's net income and income per share would have
been reduced to the pro forma amounts shown below:

For the options granted during 1998, 1997 and 1996, the weighted-average fair

The weighted-average fair value at date of grant for stock purchase shares
during 1998, 1997 and 1996 was $1.21, $2.35 and $.96 per share, respectively.
The discounted value of the stock purchase plan shares granted in 1998, 1997 and
1996 using the Black-Scholes option-pricing model was $465,000, $277,000 and
$178,000, respectively. At December 31, 1998, the Company had reserved 5,959,853
shares of Common Stock for future issuance in connection with the four
stock-based compensation plans.

     On May 29, 1996, the Company completed the sale of 989,406 shares of its
Common Stock at a price to the public of $15.875 per share. A portion of the net
proceeds from the sale of approximately $14.6 million was used to make the $10.0
million principal payment due June 30, 1996, on the Senior Notes.

     During 1997, the Company adopted a Stockholder Rights Plan ("Rights Plan").
As part of the Rights Plan, the Company's Board of Directors declared a dividend
of one preferred stock purchase right ("Right") for each share of the Company's
Common Stock outstanding on November 27, 1997. The Board also authorized the
issuance of one such Right for each share of the Company's Common Stock issued
thereafter.

     The Rights will become exercisable only if, without the prior approval of
the Board, a person or group acquires 15% or more of Varco's Common Stock or
announces a tender or exchange offer, the consummation of which would result in
ownership by a person or group of 15% or more of the Common Stock.

                                     [ $ ]


     Each Right will entitle its holder to purchase one one-thousandth of a
share of a new series of the Company's Preferred Stock at an exercise price of
$140.00. If a person or group acquires 15% or more of the Company's outstanding
Common Stock, each Right will entitle its holder (other than the acquiring
person or group) to purchase at the Right's then-current exercise price, a
number of shares of Varco Common Stock (or in certain circumstances, cash,
property or other securities) having a market value equal to twice the exercise
price. In addition, if at any time after such an acquisition, the Company is
acquired in a merger or other business combination transaction or 50% or more of
its consolidated assets or earning power are sold, each outstanding Right will
entitle its holder (other than the acquiring person or group) to purchase, at
the Right's then-current exercise price, a number of the acquiring person's
common shares having a market value equal to twice the exercise price.

     Following the acquisition by a person or group of beneficial ownership of
15% or more of the Company's Common Stock and prior to an acquisition of 50% or
more of the Common Stock, the Board of Directors may exchange the Rights (other
than Rights owned by the acquiring person or group), in whole or in part, at an
exchange ratio of one share of Common Stock (or in certain circumstances, cash,
property or other securities) per Right.

     Prior to the acquisition by a person or group of 15% or more of the Common
Stock, the Rights are subject to redemption at the option of the Board of
Directors at a price of $0.01 per Right. The Rights currently trade with the
Company's Common Stock, have no voting or dividend rights and expire on November
5, 2007.

                         Commitments and contingencies

The Company leases land and its executive offices in Orange, California under
two operating leases, from certain officers, directors, and shareholders of the
Company. The land lease expires in 2012, has an annual aggregate rental of
$480,000 (subject to upward adjustment in 2002 based on appraisals) plus real
estate taxes and other expenses. The Company has the option to purchase the
leased land at a price equal to the greater of the original cost of the property
to the lessors or the fair market value at the time of purchase. The office
lease expires in 2005 and has an aggregate annual rental of $378,000 (subject to
periodic upward adjustments based upon the consumer price index.) The Company
has an option to extend this lease for 60 months based on the then fair market
rent of the building.

     The Company leases most of its sales, service and distribution facilities
under agreements ranging from one to eight years.

     Approximate minimum annual rental payments under noncancellable operating
leases as of December 31, 1998 are as follows:

Rent expense amounted to $8,867,000, $6,696,000, and $5,185,000 for 1998, 1997,
and 1996, respectively.

     The Company is sometimes named as a defendant in litigation relating to the
products and services it provides. The Company insures against these risks to
the extent deemed prudent by its management, but no assurance can be given that
the nature and amount of such insurance will in every case fully indemnify the
Company against liabilities arising out of pending and future legal proceedings
relating to its ordinary business activities. The Company provides for costs
related to these contingencies when a loss is probable. It is the opinion of
management that it is remote that there will be an unfavorable resolution in
excess of amounts previously provided.

     The Company has been designated as a potentially responsible party ("PRP")
for two separate waste disposal sites. With respect to both of the sites,
numerous other PRPs have similarly been designated. The Company has contribution
agreements with other PRPs, and settlements and costs paid by the Company have
not been significant. In the opinion of the Company's management neither these
nor other environmental matters would have a material adverse effect on the
consolidated financial position of the Company.

                                 Benefit Plans

In February 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standard No. 132, "Employers' Disclosures about Pensions
and Other Postretirement Benefits" ("Statement 132") Statement 132 does not
change the measurement or recognition provisions of previously issued standards,
but revises disclosures about pensions and other postretirement benefit plans.
The Company adopted Statement 132 in 1998. Restatement of disclosures for the
prior years has been made for comparative purposes.

     The Company has a contributory profit sharing plan covering eligible U.S.
employees and certain foreign employees with more than one year's service. Under
the plan, the Company contributes from 2% to 20% of its net income (as defined)
at the discretion of the Board of Directors. The total contribution may not
exceed the maximum amount allowable for income tax purposes. Contributions to
the plan amounted to $6,500,000, $5,000,000, and $2,400,000, for 1998, 1997 and
1996, respectively. In 1993, the Company amended its Profit Sharing Plan to
designate a portion of profit sharing contributions for retiree healthcare and
life insurance benefits for certain eligible employees retiring after December
31, 1993. In 1995 the plan was further amended to include an employer matching
contribution. The Company's matching contribution amounted to $1,084,000,
$831,000 and $651,000 in 1998, 1997, and 1996, respectively.

     The Company also has a supplemental defined benefits plan providing
retirement and death benefits for a number of key employees. The plan is
unfunded and the net pension liability was $3,396,000 and $2,811,000 at December
31, 1998 and 1997, respectively. Expense under the plan was $723,000, $652,000,
and $602,000 in 1998, 1997, and 1996, respectively.

     For certain former employees who retired prior to December 31, 1993,
healthcare and life insurance benefits are provided through insurance companies.
In 1993 the Company adopted FASB Statement No. 106, "Accounting for
Postretirement Benefits Other Than Pensions". The transition obligation is being
amortized over 20 years.

     The assumed weighted-average annual rate of increase in the per capita cost
of covered benefits is 8% for 1998 and is assumed to decrease gradually to 4.5%
for 2010 and remain at that level thereafter. The health care cost trend rate
assumption has a significant effect on the amounts reported. For example,
increasing the assumed health care cost trend rates by one percentage point in
each year would increase the accumulated postretirement benefit obligation as of
December 31, 1998, by $870,000 and the aggregate of the service and interest
cost components of net periodic postretirement benefit cost for 1998 by $70,000.

     The weighted-average discount rate used in determining the accumulated
postretirement benefit obligation was 6.75% and 7% at December 31, 1998 and
1997, respectively.

     Net periodic postretirement benefit cost includes the following components:

The Company has an Executive Management Savings Plan and a Directors Saving Plan
(the Plans) which permit eligible executives and the Company's non-employee
directors to defer a portion of their compensation. Participants in the Plans
may also participate in the Company's "split-dollar" life insurance program
pursuant to which the Company will purchase a life insurance policy for a
premium equal to the amounts deferred plus any additional amount required to
provide a minimum death benefit. Amounts payable to a participant under the
Plans are offset by any benefits paid under the participant's life insurance
policy. The life insurance policies are intended to provide security for the
payment of benefits under the Plans.

                  Business Segment and Geographic Information

Effective January 1, 1998, the Company adopted the Financial Accounting
Standards Board's Statement of Financial Accounting Standards No. 131,
"Disclosures about Segments of an Enterprise and Related Information"
("Statement 131"). Statement 131 superseded FASB Statement No. 14, "Financial
Reporting for Segments of a Business Enterprise". Statement 131 establishes
standards for the way that public business enterprises report information about
operating segments in annual financial statements and requires that those
enterprises report selected information about operating segments in interim
financial reports. Statement 131 also establishes standards for related
disclosures about products and services, geographic areas, and major customers.
The adoption of Statement 131 did not affect results of operations or financial
position, but did affect the following disclosure of segment information.

     The Company has five reportable segments--its five Divisions described in
Note a. The accounting policies of the reportable segments are the same as those
described in the summary of significant accounting policies except that certain
expenses, such as interest, amortization of certain intangibles, special charges
and general corporate expenses are not allocated to the Divisions. In addition,
certain assets including cash and cash equivalents, deferred taxes, and certain
intangible assets are not allocated to the Divisions.

     Intersegment sales are recorded at the selling Division's cost plus profit
which is calculated as a fixed percentage mark-up on cost.

     The reportable segments are each managed separately because they
manufacture and distribute distinct products with different production
processes, and each Division has its own President that reports directly to the
Chief Executive Officer of the Company.

                         REPORT OF INDEPENDENT AUDITORS


Shareholders and Board of Directors
Varco International, Inc.

We have audited the accompanying consolidated balance sheets of Varco
International, Inc. and subsidiaries as of December 31, 1998 and 1997, and the
related consolidated statements of income, shareholders' equity and cash flows
for each of the three years in the period ended December 31, 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform 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
Varco International, Inc. and subsidiaries at December 31, 1998 and 1997, and
the consolidated results of their operations and their cash flows for each of
the three years in the period ended December 31, 1998, in conformity with
generally accepted accounting principles.

                                Dividend Policy

The payment of dividends (other than dividends payable solely in shares of
Common Stock) on, and repurchases of, Common Stock are restricted by the Note
Agreement between Varco and its institutional lenders and Varco's revolving
Credit Agreement with three financial institutions. Under the revolving Credit
Agreement, which is generally the more restrictive, the amount available for the
payment of dividends on, and repurchases of, Common Stock is limited to
$5,000,000 plus 25% of Varco's consolidated net income arising after June 30,
1997, computed on a cumulative basis. At December 31, 1998, the amount available
for dividends and repurchases under the credit agreement was $28,015,000. The
Company may also purchase or otherwise acquire shares of Common Stock from the
proceeds of the substantially concurrent sale of shares of Common Stock.

     The Company has not paid a dividend on the Common Stock since 1982, and the
Board of Directors presently has no plans to resume the payment of dividends.
