PART I

ITEM 1. BUSINESS

Rowan Companies, Inc. (hereinafter referred to as "Rowan" or "the Company") is a
major provider of international and domestic contract drilling and aviation
services. Rowan also operates a mini-steel mill, a manufacturing facility that
produces heavy equipment for the mining, timber and transportation industries
and a drilling products group that has designed or built about one-third of all
mobile offshore jack-up drilling rigs. Rowan was organized in 1947 as a Delaware
corporation and a successor to a contract drilling business conducted since 1923
under the name Rowan Drilling Company, Inc.

Our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports
on Form 8-K and amendments to those reports filed or furnished pursuant to
Section 13(a) or 15(d) of the Exchange Act are made available free of charge on
our internet website at http://www.rowancompanies.com as soon as reasonably
practicable after we electronically file such material with, or furnish it to,
the Securities and Exchange Commission.

Information regarding each of Rowan's industry segments, including revenues,
operating profit (loss), assets and foreign-source revenues for 2003, 2002 and
2001 is incorporated herein by reference from Footnote 10 of the Notes to
Consolidated Financial Statements on pages 35 and 36 of Rowan's 2003 Annual
Report to Stockholders ("Annual Report"), incorporated portions of which are
filed as Exhibit 13 hereto.

During 2003, 14% of Rowan's consolidated revenues were derived from El Paso
Corporation and 10% were derived from Anadarko Petroleum Corporation, primarily
from drilling services. In 2002, 13% of Rowan's consolidated revenues were
derived from El Paso Corporation, primarily from drilling services. In 2001, 14%
of Rowan's consolidated revenues were derived from Anadarko Petroleum
Corporation, primarily from drilling services.

DRILLING OPERATIONS

Rowan provides contract drilling services utilizing a fleet of 23 self-elevating
mobile offshore drilling platforms ("jack-up rigs"), one mobile offshore
floating platform ("semi-submersible rig") and 18 land drilling rigs. Rowan's
drilling operations are conducted primarily in the Gulf of Mexico, the North
Sea, offshore eastern Canada and in Texas and Louisiana. In 2003, drilling
operations generated an operating profit (income from operations before
deducting general and administrative expenses) of $30.6 million.

Offshore Operations

Since 1970, Rowan's drilling operations have featured jack-up rigs performing
both exploratory and development drilling and, in certain areas, well workover
operations. Rowan operates larger, deep-water type jack-up rigs capable of
drilling to depths of 20,000 to 35,000 feet in maximum water depths ranging from
250 to 550 feet, depending on the size of the rig and its location.

Rowan's jack-up rigs are designed with a floating hull with three independently
elevating legs, drilling equipment, supplies, crew quarters, loading and
unloading facilities, a helicopter landing deck and other related equipment.
Drilling equipment includes engines, drawworks or hoist, derrick, pumps to
circulate the drilling fluid, drill pipe and drilling bits. Rowan's rigs are
equipped with propulsion thrusters to assist in towing. At the drilling site,
the legs are lowered until they penetrate the ocean floor and the hull is
jacked-up on the legs to the desired elevation above the water. The hull then
serves as a drilling platform until the well is completed, at which time the
hull is lowered into the water, the legs are elevated and the rig is towed to
the next drilling site.

1


Rowan's cantilever jack-ups can extend a portion of the sub-structure containing
the drawworks, derrick and related equipment over fixed production platforms so
that development or workover operations on the platforms can be carried out with
a minimum of interruption to production. In 1989, Rowan acquired and developed a
"skid base" technology, whereby the rig floor drilling equipment on a
conventional jack-up rig can be "skidded" out over the top of a fixed platform.
Thus, conventional jack-up rigs can be used on certain drilling assignments that
previously required a cantilever jack-up or platform rig.

At March 12, 2004, Rowan's offshore drilling fleet included the following:

- 16 cantilever jack-up rigs, featuring three harsh environment "Gorilla
class" rigs and four enhanced "Super Gorilla class" rigs

- seven conventional jack-up rigs, including five rigs with skid base
capability

- one semi-submersible rig

The fleet increased to 24 units following the delivery in August 2003 of the Bob
Palmer. The Company operates two of the cantilever jack-up rigs under operating
leases expiring in 2008.

Rowan's Gorilla class rigs are a heavier-duty class of jack-up rig, capable of
operating in water depths up to 328 feet in extreme hostile environments (winds
up to 100 miles per hour and seas up to 90 feet) such as in the North Sea and
offshore eastern Canada. Gorillas II and III can drill up to 30,000 feet and
Gorilla IV is equipped to reach 35,000 feet.

During the fourth quarter of 1998, Rowan completed construction of its first
Super Gorilla class rig, Rowan Gorilla V. Construction of Rowan Gorilla VI was
completed in June 2000, and Rowan Gorilla VII was delivered in December 2001.
Gorillas V, VI and VII are enhanced versions of Rowan's Gorilla class rigs,
featuring a combination drilling and production capability. They can operate
year-round in 400 feet of water south of the 61st parallel in the North Sea,
within the worst-case combination of 100-year storm criteria for waves, wave
periods, winds and currents. Rowan financed $153.1 million of the cost of
Gorilla V, $171.0 million of the cost of Gorilla VI and $185.4 million of the
cost of Gorilla VII through bank loans guaranteed by the U.S. Department of
Transportation's Maritime Administration under its Title XI Program.

In August 2003, Rowan completed construction of the Bob Palmer (formerly Gorilla
VIII), an enhanced version of the Super Gorilla class jack-up designated a Super
Gorilla XL. The Bob Palmer has 713 feet of leg, 139 feet more than Gorillas V,
VI or VII, and has 30% larger spud cans, enabling operation in the Gulf of
Mexico in water depths up to 550 feet. The Bob Palmer can also operate in water
depths up to 400 feet in the hostile environments offshore eastern Canada and in
the North Sea. Rowan financed $187.3 million of the cost of the Bob Palmer
through bank loans guaranteed under the Title XI Program.

In July 2001, Rowan's Board of Directors approved the development, design and
construction of a new class of jack-up rig, specifically targeted for deep
drilling in water depths up to 250 feet on the Gulf of Mexico's outer
continental shelf. The Tarzan Class rig will offer drilling capabilities similar
to our Gorilla class jack-ups, enabling more efficient drilling beyond 15,000
feet, but with reduced environmental criteria (wind, wave and current) and at
less than one-half of the construction cost. The first of as many as four new
Tarzan rigs, the Scooter Yeargain, is at Sabine Pass, Texas for final outfitting
and should be delivered in April 2004. The second Tarzan Class rig, the Bob
Keller, formerly Tarzan II, is under construction at Vicksburg, Mississippi,
with delivery expected during the third quarter of 2005. Rowan has obtained
financing for up to $180.9 of the cost of the first two Tarzan rigs through
government-guaranteed Title XI bank loans, under terms and conditions similar to
those in effect for the Bob Palmer, and has applied for Title XI financing for
Tarzans III and IV.

2


The current fleet expansion program began in 1995 and represents Rowan's first
new construction since the mid-1980s. In the intervening period, Rowan's capital
expenditures were primarily for enhancements to existing drilling rigs and
manufacturing facilities and for the purchase of aircraft. Of Rowan's 16
remaining jack-up rigs, six cantilever rigs and one conventional rig have been
modified to provide a degree of hostile environment operating capability, and
seven cantilever rigs and three conventional rigs are equipped to operate in
water depths up to 350 feet.

Rowan takes advantage of lulls in drilling activity to perform needed
maintenance and make certain enhancements to its drilling fleet. During 1998 and
1999, the Company completed the following enhancements: upgrading solids control
mud systems on all nine of the Company's 116-C class jack-up rigs; adding one to
two engines to six of the 116-C class rigs, each such rig now being equipped
with six engines; installing new generation top-drives on four of the 116-C
class rigs and one of the Gorilla class rigs; upgrading the electrical systems
on one of the 84 class rigs; adding leg length to three of the 116-C class rigs
and reconditioning the subsea equipment on the semi-submersible rig.

For a further discussion of Rowan's availability of funds in 2004 to sustain
operations, debt service and planned capital expenditures, including those
related to construction of the Tarzan Class rigs, see "Liquidity and Capital
Resources" under "Management's Discussion and Analysis of Financial Condition
and Results of Operations" on pages 20 through 22 of the Annual Report, which
information is incorporated herein by reference. Also, see ITEM 2. PROPERTIES
beginning on page 15 of this Form 10-K for additional information with respect
to the capabilities and operating status of the Company's rigs.

Rowan's semi-submersible rig is utilized principally for offshore exploratory
drilling from a floating position and is capable of drilling to a depth of
25,000 feet in water depths up to 1,200 feet. A semi-submersible drilling rig
consists of a drilling platform raised above multiple hulls by columns. The
hulls are flooded and submerged beneath the water surface, in which position the
rig is anchored during drilling operations. The drilling platform contains the
same type of equipment found on a jack-up rig. After completion of the well, the
submerged hull is deballasted to reduce vessel draft and facilitate towing to
another drilling location.

Rowan operates six anchor-handling, towing and supply (AHTS) boats obtained
under five-year lease agreements that expire in 2004 (one boat) and 2005 (five
boats) and contain purchase options. The boats are fully crewed by the lessor,
but managed by Rowan to provide towing and supply services to our drilling
operations. Rowan also directly markets the boats to third parties, with
emphasis on their anchor-handling capabilities for deepwater semi-submersibles.

Onshore Operations

Rowan has drilling equipment, personnel and camps available on a contract basis
for exploration and development of onshore areas. Rowan currently owns 18
deep-well land rigs located as follows: 12 in Texas and six in Louisiana. The
fleet features four newly constructed rigs and nine rigs that have been
substantially rebuilt in recent years.

The drilling equipment comprising an onshore rig consists basically of engines,
drawworks or hoist, derrick, pumps to circulate the drilling fluid, drill pipe
and drilling bits. The type of rig required by a customer depends upon the
anticipated well depth, terrain and conditions in the drilling area.

3


Contracts

Rowan's drilling contracts generally provide for compensation on a day rate
basis, whereby the Company earns a fixed amount per day, and are usually
obtained either through competitive bidding or individual negotiations. A number
of factors affect a drilling contractor's ability, both onshore and offshore, to
obtain contracts at a profitable rate within an area. Such factors include the
location and availability of equipment, its suitability for the project, the
comparative cost of the equipment, the competence of personnel and the
reputation of the contractor. Profitability may also be dependent upon receiving
adequate compensation for the cost of moving equipment to drilling locations.

When weak market conditions characterized by declining drilling day rates
prevail, Rowan generally accepts lower rate contracts in an attempt to maintain
its competitive position and to offset the substantial costs of maintaining and
reactivating stacked rigs. When drilling markets are strong and increasing rates
prevail, Rowan generally pursues short rather than long-term contracts for its
rigs to maximize its ability to obtain rate increases and pass through any cost
increases to customers.

Rowan's drilling contracts are either "well-to-well", "multiple well" or for a
fixed term generally ranging from one to twelve months. Well-to-well contracts
are cancelable by either party upon completion of drilling at any one site, and
fixed-term contracts usually provide for termination by either party if drilling
operations are suspended for extended periods by events of force majeure. While
most fixed-term contracts are for relatively short periods, some fixed-term and
well-to-well contracts continue for a longer period than the original term or
for a specific series of wells. Many offshore contracts contain renewal or
extension provisions exercisable at the option of the customer at prices
agreeable to the Company and most require additional payments for mobilization
and demobilization costs. Rowan's contracts for work in foreign countries
generally provide for payment in United States dollars except for minimal
amounts required to meet local expenses, such as payroll.

Rowan believes that the contract status of its onshore and offshore rigs is more
informative than backlog calculations, and that backlog information is neither
calculable nor meaningful given the cancellation options contained in, and the
short duration of, fixed-term contracts and the indeterminable duration of
well-to-well and multiple well contracts. See ITEM 2. PROPERTIES beginning on
page 15 of this Form 10-K for the contract status of the Company's rigs as of
March 12, 2004.

Competition

The contract drilling industry is highly competitive and involves many factors,
including price, equipment capability, operating and safety performance and
reputation. Rowan believes that it competes favorably with respect to all of
these factors.

Rowan competes with more than 20 offshore drilling contractors together having
available more than 500 mobile rigs worldwide and approximately 20 domestic
drilling contractors with about 200 available deep-well land rigs in the
aggregate. Based upon the number of rigs as tabulated by ODS-Petrodata, Rowan is
the seventh largest offshore drilling contractor in the world and the sixth
largest jack-up rig operator. Some of the Company's competitors have greater
financial and other resources and may be more able to make technological
improvements to existing equipment or replace equipment that becomes obsolete.

4


Technological advances can create competitive advantages and eventually cause
less capable equipment to be less suitable for certain drilling operations. As a
result, during the 1980-1986 period, Rowan carried out a drilling rig expansion
program, culminating with the development of a heavier jack-up rig class known
as the Gorilla rig. Since that time, Rowan has employed a drilling rig
modification and enhancement program designed to provide a fleet of jack-up rigs
reflecting the latest technological advancements. In 1995, Rowan began a
drilling rig expansion program featuring the development of enhanced versions of
the Gorilla class rig and, beginning in 2001, the Tarzan Class rig.

The offshore markets in which the Company competes are characterized by their
economic viability and political stability. At March 12, 2004, Rowan had 21
jack-ups and its semi-submersible located in the Gulf of Mexico, one jack-up
located offshore eastern Canada and one jack-up located in the North Sea. Based
upon the number of rigs as tabulated by ODS-Petrodata, Rowan is the fourth
largest offshore drilling contractor in the Gulf of Mexico and the second
largest jack-up rig operator in the area. Relocation of equipment from one
geographic location to another is dependent upon changing market dynamics, with
moves occurring only when the likelihood of higher returns makes such action
economical over the longer term. During 1999 and 2000, the Company relocated its
six rigs from the North Sea to the Gulf of Mexico (five rigs) and offshore
eastern Canada (one rig) and two rigs from offshore eastern Canada to the Gulf
of Mexico to pursue more favorable market conditions. Gorilla VII was relocated
from the Gulf of Mexico to the North Sea in January 2002.

Rowan markets its drilling services by directly contacting present and potential
customers, including large international energy companies, many smaller energy
companies and foreign government-owned or controlled energy companies. Since
1992, with the many restructurings, downsizings and, more recently, mergers by
major energy companies, followed by significant reductions in their domestic
budgets, the Company has increased its marketing emphasis on independent
operators.

See "Management's Discussion and Analysis of Financial Condition and Results of
Operations" on pages 16 through 22 of Rowan's 2003 Annual Report, the
information under which caption is incorporated herein by reference, for a
discussion of current industry conditions and their impact on operations.

Regulations and Hazards

Rowan's drilling operations are subject to many hazards, including blowouts and
well fires, which could cause personal injury, suspend drilling operations,
seriously damage or destroy the equipment involved and cause substantial damage
to producing formations and the surrounding areas. Offshore drilling operations
are also subject to marine hazards, either while on site or under tow, such as
vessel capsizing, collision or grounding. Raising and lowering the legs of
jack-up rigs into the ocean bottom and ballasting semi-submersible units require
skillful handling to avoid capsizing or other serious damage. Drilling into
high-pressure formations is a complex process and problems can frequently occur.

Rowan believes that it is adequately insured for physical damage to its rigs,
and for marine liabilities, worker's compensation, maritime employers liability,
automobile liability and for various other types of exposures customarily
encountered in the Company's operations. Certain of Rowan's liability insurance
policies specifically exclude coverage for fines, penalties and punitive or
exemplary damages. Rowan anticipates that its present insurance coverage will be
maintained, but no assurance can be given that insurance coverage will continue
to be available at rates considered reasonable, that self-insured amounts or
deductibles will not increase or that certain types of coverage will be
available at any cost.

5


Foreign operations are often subject to political, economic and other
uncertainties not encountered in domestic operations, such as arbitrary taxation
policies, onerous customs restrictions, unstable currencies and the risk of
asset expropriation due to foreign sovereignty over operating areas. As noted
previously, Rowan attempts to minimize the risk of currency rate fluctuations by
generally contracting for payment in United States dollars.

Many aspects of Rowan's operations are subject to government regulation, as in
the areas of equipping and operating vessels, drilling practices and methods and
taxation. In addition, various countries (including the United States) have
regulations relating to environmental protection and pollution control. Recent
events have also increased the sensitivity of the oil and gas industry to
environmental matters. Rowan could become liable for damages resulting from
pollution of offshore waters and, under United States regulations, must
establish financial responsibility. Generally, Rowan is substantially
indemnified under its drilling contracts for pollution damages, except in
certain cases of pollution emanating above the surface of land or water from
spills of pollutants, or in the case of pollutants emanating from the Company's
drilling rigs, but no assurance can be given regarding the enforceability of
such indemnification provisions.

Rowan believes that it complies in all material respects with legislation and
regulations affecting the drilling of oil and gas wells and the discharge of
wastes. To date, the Company has made significant modifications to its Gulf of
Mexico rigs to reduce waste and rain water discharge and believes that it could
operate those rigs at "zero discharge" without material additional expenditures.
Otherwise, regulatory compliance has not materially affected the capital
expenditures, earnings or competitive position of the Company to date, although
such measures do increase drilling costs and may reduce drilling activity.
Further regulations may reasonably be anticipated, but any effects thereof on
Rowan's drilling operations cannot be accurately predicted.

Rowan is subject to the requirements of the Federal Occupational Safety and
Health Act ("OSHA") and comparable state statutes. OSHA's hazard communication
standard, the Environmental Protection Agency's "community right-to-know"
regulations and comparable state statutes require Rowan to organize and report
certain information about the hazardous materials used in its operations to
employees, state and local government authorities and local citizens.

Since the exploration activities of Rowan's present and potential customers are
directly impacted by state, federal and foreign regulations associated with the
production and transportation of oil and gas, the demand for Rowan's drilling
services is also affected.

MANUFACTURING OPERATIONS

In 1994, LeTourneau, Inc. ("LeTourneau"), a wholly-owned subsidiary of the
Company, acquired the net assets of Marathon LeTourneau Company, headquartered
in Longview, Texas. LeTourneau operates a mini-steel mill that recycles scrap
and produces steel plate; a manufacturing facility that produces heavy equipment
such as front-end loaders with up to an 80-ton capacity; and a drilling products
group that has designed or built about one-third of all mobile offshore jack-up
drilling rigs, including all 23 operated by Rowan. In 2003, the manufacturing
division generated an operating profit of $2.3 million. External manufacturing
backlog for all product lines was approximately $52 million at February 29,
2004, all of which is expected to be realized in 2004, compared with $24 million
at February 28, 2003, all of which was realized during 2003.

6


The mining equipment product line features front-end loaders with bucket
capacities of 18, 22, 28, 33 and 53 cubic yards. LeTourneau's loaders are
generally used in coal, gold, copper, diamond and iron ore mines and utilize
LeTourneau's diesel electric-drive system with digital controls. This system
allows large, mobile equipment to stop, start and reverse without gear shifting
and high maintenance braking. LeTourneau loaders can load rear-dump trucks in
the 85-ton to 400-ton range. LeTourneau's mining equipment and parts are
distributed through a worldwide network of independent distributors and its own
distribution network serving the western United States and Australia.

The timber equipment product line features diesel electric powered log stackers
with either two or four wheel drive configurations and load capacities ranging
from 35 to 55 tons. LeTourneau is one of two manufacturers that sell
electrically powered jib cranes rated from 25,000 to 52,000 lbs. at a reach of
100 to 150 feet and with a 360-degree rotation. LeTourneau's timber equipment is
marketed primarily in North America through independent dealers and its own
dealer in the northwestern United States.

LeTourneau's transportation equipment line produces several different types of
material handling equipment, such as 50-ton capacity, diesel electric, gantry
cranes used for lifting, transporting and stacking large shipping containers and
trailers at ports and rail yards. Gantry cranes can span up to seven container
rows plus a truck aisle and stack 9-1/2-feet tall containers up to five high.
Gantry cranes equipped with a spreader can lift containers from the top and have
retractable arms for loading and unloading piggyback trailers. LeTourneau's
transportation equipment is marketed primarily in North America through
independent dealers and its own dealer in the northwestern United States.

LeTourneau also sells parts and components to repair and maintain mining, timber
and transportation equipment. Equipment parts are marketed through two
independent dealers and its own dealer in the United States with 16
parts-stocking locations, one dealer in Canada with 12 parts-stocking locations,
and 25 independent international dealers and its own Australian dealer with 40
parts-stocking locations.

LeTourneau's Longview, Texas mini-steel mill produces carbon, alloy and
specialty steel plate products. LeTourneau concentrates on "niche" markets that
require alloy, specialty steel grades, or "exotic" versions of carbon steel
products, including mold steels, tool steels, aircraft quality steels, 400
series stainless steel and hydrogen-induced, crack-resistant steels. External
steel sales, which are garnered through a direct sales force, consist primarily
of steel plate, but also include forging ingots and value-added fabrication of
steel products. Steel products are generally sold to steel service centers,
fabricators, manufacturers and forge shops. The market for carbon steel plate
products and fabricated products is regional and encompasses Texas, Oklahoma,
Louisiana, Mississippi and Arkansas. LeTourneau ships alloy and specialty grades
of plate products nationally and exports quantities to Mexico and Canada. The
forging ingot market is concentrated in the Gulf Coast region of Texas. Carbon
and alloy plate products are also used internally in the production of heavy
equipment and parts.

LeTourneau's Vicksburg, Mississippi shipyard was reactivated during 1995-1996
following Rowan's announcement of the planned construction of Rowan Gorilla V
and is dedicated to providing equipment, spare parts and engineering support to
the offshore drilling industry. The yard currently employs about 700 people,
most of whom have been hired since 1995. Some rig component manufacturing and
rig repair services, as well as design engineering, continue to be performed at
the Longview, Texas facility.

As noted previously, the drilling products group completed Rowan Gorilla V in
late 1998 and Rowan Gorilla VI in June 2000, delivered Rowan Gorilla VII during
December 2001 and the Bob Palmer during August 2003, and is currently
constructing for the Company the first two of as many as four Tarzan Class
jack-up rigs. The drilling products group also completed two Super 116-C class
jack-up rig kits for others in 1998.

7


LeTourneau engages in a limited amount of research and product development,
primarily to increase the capacity of and provide innovative improvements to its
product lines. The Company evaluates on an ongoing basis the manufacturing
product and service lines with the intention of making enhancements.

During January 2000, LeTourneau completed the purchase of The Ellis Williams
Company, Inc. and EWCO, Inc. dba Traitex Machine Co., which collectively design
and manufacture mud pumps in a wide range of sizes for a variety of
applications. The purchase price was approximately $10 million, with $7 million
in cash and the balance in promissory notes due over a three-year period. The
notes were repaid in full during 2001.

During January 2002, the Company completed the purchase of certain assets of
Oilfield-Electric-Marine, Inc. and Industrial Logic Systems, Inc. (OEM), issuing
from treasury 439,560 shares of Rowan common stock valued at approximately $8
million. OEM manufactures variable speed AC motors and variable frequency drive
systems, DC motors and drive systems, and consoles for marine boats and lay
barges, the oil and gas drilling industry, and the mining and dredging
industries. Additionally, OEM manufactures medium voltage switchgear from 5KV
through 38KV for the industrial and petrochemical markets.

Raw Materials

The principal raw material utilized in LeTourneau's manufacturing operations is
steel plate, much of which is supplied by LeTourneau's mini-steel mill. Other
required materials are generally available in sufficient quantities to meet its
manufacturing needs through purchases in the open market. LeTourneau does not
believe that it is dependent on any single supplier.

Competition

LeTourneau's mining equipment competes worldwide with several competitors.
LeTourneau's loader product line has only two direct competitors; however, the
larger loader models compete with other types of loading equipment, primarily
electric and hydraulic mining shovels. Based upon internal marketing studies,
LeTourneau's share of the small-loader market (1,000 horsepower and below) has
decreased to less than 1% in recent years due to the availability of smaller
(and cheaper) alternatives. In the large-loader market (above 1,000 horsepower),
LeTourneau has achieved about a 50% share of both domestic and export sales over
the past seven years.

The market for LeTourneau's timber equipment is also characterized by vigorous
competition. Though LeTourneau's jib crane is unique, it does encounter
competition from other equipment manufacturers that offer alternative methods
for meeting customer requirements. The number of major competitors by type of
equipment is as follows: log stackers - four and jib cranes - three.
LeTourneau's estimated share of the domestic log-stacker market is around 20%
and its estimated share of the Canadian market is around 15%.

LeTourneau's mini-steel mill encounters competition from a total of six major
competitors, with the breakdown by product line being as follows: plate products
- - four and fabricated products - two. LeTourneau's share of the overall steel
market is negligible. The internal requirements of the equipment and drilling
products groups provide a base load for the steel mill, and LeTourneau uses a
small, direct sales force to sell specialized alloy, carbon and tool steel
products to steel service centers, fabricators, manufacturers and brokers.

The competition LeTourneau encounters in the parts business is fragmented with
only three other companies being considered to be direct competitors. Vendors
supplying parts directly to end users and well-fitters who obtain and copy parts
for cheaper and lower quality substitutes provide more intense competition than
LeTourneau's direct competitors.

8


LeTourneau markets and sells its equipment and support parts primarily through
an established international dealer association. LeTourneau dealers are
predominantly independent business organizations and all have established dealer
agreements with LeTourneau. The dealers are responsible for selling equipment on
behalf of LeTourneau to end users and providing the necessary follow-up service
and parts supply directly to those end users.

To be competitive in the mining and timber equipment markets, LeTourneau offers
warranties at the time of purchase and parts guarantees. The warranties extend
for stipulated periods of ownership or hours of usage, whichever occurs first.
Parts consumption guaranties and maintenance and repair contracts are made on
the same basis. LeTourneau's parts-return policy provides that returned parts
must be in new, usable condition, in current production and readily resalable.

Since 1955, when the first LeTourneau unit was delivered, LeTourneau has been
recognized as a leading designer and builder of "jack-up" drilling rigs.
Currently, there are nine competitive jack-ups under construction worldwide, two
of which are LeTourneau's Tarzan Class rigs. At present, LeTourneau has a
limited number of competitors in the rig construction and support industry.
However, there are numerous shipyard facilities with the capability for jack-up
construction.

LeTourneau's two principal competitors in the mud pump business have a combined
market share approaching 90%.

Historically, LeTourneau's customer base has been diverse, such that none of its
product lines have been dependent upon any one customer or small group of
customers.

Regulations and Hazards

LeTourneau's manufacturing operations and facilities are subject to regulation
by a variety of local, state and federal agencies which regulate safety and the
discharge of materials into the environment, including the Environmental
Protection Agency (EPA), the Texas Commission on Environmental Quality (TCEQ)
and the Mississippi Department of Environmental Quality. LeTourneau's
manufacturing facilities are also subject to the requirements of OSHA and
comparable state statutes.

Hazardous materials are generated at LeTourneau's Longview, Texas plant in
association with the steel making process. Industrial wastewater generated at
the mini-steel mill facility for cooling purposes is recirculated and quality
tests are conducted regularly. The facility has permits for wastewater
discharges, solid waste disposal and air emissions. Waste products considered
hazardous by the EPA are disposed of by shipment to an EPA or state approved
waste disposal facility.

LeTourneau jack-up designs are subject to regulatory approval by various
agencies, depending upon the geographic areas where the rig will be qualified
for drilling. The rules vary by location and are subject to frequent change, and
primarily relate to safety and environmental issues, in addition to those which
classify the jack-up as a vessel.

LeTourneau may be liable for damages resulting from pollution of air, land and
inland waters associated with its manufacturing operations. LeTourneau believes
that compliance with environmental protection laws and regulations will have no
material effect on its capital expenditures, earnings or competitive position
during 2004. Further regulations may reasonably be anticipated, but any effects
thereof on the Company's manufacturing operations cannot be accurately
predicted.

9


As a manufacturing company, LeTourneau may be responsible for certain risks
associated with the use of its products. These risks include product liability
claims for personal injury and/or death, property damage, loss of product use,
business interruption and necessary legal expenses to defend LeTourneau against
such claims. LeTourneau carries insurance that it believes adequately covers
such risks. LeTourneau did not assume certain liabilities of Marathon LeTourneau
Company, such as product liability and tort claims, associated with all products
manufactured, produced, marketed or distributed prior to the date of the
acquisition.

LeTourneau anticipates incurring expenses associated with the warranty of its
products. In the equipment business, dealers of LeTourneau's products perform
the warranty work while in the rig construction business, LeTourneau generally
performs warranty work directly.

AVIATION OPERATIONS

Rowan's wholly-owned subsidiary, Era Aviation, Inc. ("Era"), provides contract
and charter helicopter and fixed-wing aviation services principally in Alaska,
the coastal areas of Louisiana and Texas, and the western United States, with
its fleet consisting on March 12, 2004 of 85 helicopters and 16 fixed-wing
aircraft. In 2003, the aviation division incurred an operating loss of $5.4
million.

Era's helicopter services in recent years have featured flightseeing, forest
fire control and support for oil and gas related operations from its primary
bases in Alaska, Louisiana and Nevada. Services provided offshore Louisiana and
Texas are primarily oil and gas-related while the majority of helicopter
services in the western United States are provided to governmental agencies in
support of forest fire control, construction and other utility work.

Based on the number of helicopters operating, Era is the largest helicopter
operator in Alaska. It provides charter services from bases at Anchorage,
Deadhorse (on the North Slope), Juneau, Kenai and Valdez. Era's charter and
contract services are provided throughout Alaska with particular emphasis in the
oil, mining and high-density tourist regions within the state. During 2003, the
Alaska helicopter operations contributed approximately 26% of the Company's
aviation revenues.

Helicopters are usually operated on a seasonal basis in Alaska because of the
prevalent climatic conditions. The peak utilization period in Alaska is May
through September, with the winter months comprising the least active period.
The seasonal nature of the Alaska business has been offset in prior years by
establishing a helicopter operation in the Gulf of Mexico area and by moving
helicopters on a limited basis to the west and northwest regions of the United
States and various overseas locations.

Since 1983, Era has operated a scheduled regional airline service in Alaska
encompassing the transportation of passengers, mail and cargo. Era currently
serves Valdez, Kenai, Homer, Kodiak and Cordova. In addition, it services 17
remote villages from its hub in Bethel, Alaska. Era operates under a code
sharing agreement with Alaska Airlines, which is the largest carrier of
passengers from the contiguous United States to Alaska. Based on revenue
passenger miles, Era's regional airline is the largest airline operation of that
type within the state of Alaska and, including the large jet carriers, is the
third largest carrier of passengers into and out of the Ted Stevens Anchorage
International Airport. During 2003, the commuter airline contributed
approximately 30% of the Company's aviation revenues.

10


Since 1979, Era has been providing charter and contract helicopter services in
the Gulf of Mexico area, primarily to the offshore oil and gas industry.
Operations are conducted from the division office in Lake Charles, Louisiana and
from bases in the Louisiana cities of Morgan City, Cameron, New Iberia,
Intracoastal City, Venice, Fourchon, Houma, Schriever and Johnson Bayou and the
Texas cities of Houston, Corpus Christi, Bay City and Sabine Pass. Based on the
number of helicopters operating, Era is the third largest helicopter operator in
the Gulf of Mexico. During 2003, the Gulf of Mexico helicopter operations
contributed approximately 38% of the Company's aviation revenues.

Since 1987, Era has manufactured and marketed, from its Gulf Coast Division
facility at Lake Charles, Louisiana, a composite external auxiliary fuel tank
for use on several helicopters, including the Bell 205, 212 and 412, the
military "Huey" and the Eurocopter BK-117. The tank system provides enhanced
flight range with nominal drag while increasing the passenger capacity. Sales to
date have been to both civilian and military customers, including emergency
float systems for US Army UH-1 Helicopters. Other aircraft accessories are also
manufactured at the facility.

During 2001, the Company committed to purchase three Sikorsky S-92 helicopters
for the Gulf of Mexico deepwater drilling market, subject to obtaining long-term
operating contracts. The S-92 design features a 19-passenger capacity and a
range of 475 nautical miles. Rowan currently expects the helicopters to be
available in the first half of 2005 and that their total cost will approach $50
million.

Contracts

Era's flight services generally are provided through master service agreements,
term contracts or day-to-day charter arrangements. Master service agreements
require incremental payments based on usage, usually have fixed terms ranging
from one month to one year and generally are cancelable upon notice by either
party in 30 days or less. Term contracts generally are noncancelable and require
payments, depending upon their duration, as follows: up to one month - either
incremental payments based on usage or incremental payments plus a base daily
rental; and one month to one year - incremental payments based on usage plus a
base monthly rental. Day-to-day charters have the same compensation arrangements
as up to one-month term contracts. Because master service agreements and
day-to-day charters are Era's most prevalent contracts, the Company believes
that the contract status of its aircraft as discussed in the following paragraph
is more informative than backlog information, which it believes is neither
calculable nor meaningful.

Era aircraft at March 12, 2004 consisted of 85 helicopters (including 40 based
in Alaska and 45 in the Gulf of Mexico area) and 16 fixed-wing aircraft (based
in Alaska). The fleet contract status at that date included 20 term contracts.
The remaining aircraft were either being operated under day-to-day charters or
one or more of 80 master service agreements, or were available for operation
under day-to-day charter or other contract arrangements.

Competition

Approximately five other operators compete directly with Era in Alaska on a
contract or charter basis. Era competes over its scheduled airline routes with
up to three other carriers. In the Gulf of Mexico area, Era competes directly
with six other operators and ranks third in the number of helicopters operating
with approximately 8% of the market. A number of other helicopter operators
compete with Era in the west and northwest regions of the United States and in
overseas locations. Services under term contracts are usually obtained through a
successful bid process whereas shorter-term charters and scheduled airline
services typically involve published rates. The Company believes that
performance and safety are the key competitive factors in Era's aviation
markets.

11


Regulations and Hazards

The operation of a scheduled airline in the United States requires a certificate
under the Federal Aviation Act of 1958, as presently administered by the
Department of Transportation. The granting of a certificate is conditioned upon
a demonstration of financial ability and operational expertise. A similar
certificate authorizing the right to operate a charter service is not presently
required by any jurisdiction in Era's operating areas.

Operation of helicopters and fixed-wing aircraft, particularly under weather
conditions prevailing in Alaska, is considered potentially hazardous, although
Era conducts rigorous training and safety programs to minimize these hazards.
Era believes that it is adequately protected by public liability and property
damage insurance, including hull insurance against loss of equipment, but
carries no insurance against loss of earnings.

EMPLOYEES

Rowan had 5,282 employees at February 29, 2004 and 5,395, 5,227 and 4,943
employees at December 31, 2003, 2002 and 2001, respectively. Some of the
employees included in these numbers are not United States citizens. None of the
Company's employees are covered by collective bargaining agreements with labor
unions. Rowan considers relations with its employees to be satisfactory.

RISK FACTORS

You should consider carefully the following risk factors, in addition to the
other information contained and incorporated by reference in this Form 10-K,
before deciding to invest in our common stock.

Volatile oil and natural gas prices greatly impact demand for our offshore
drilling and related services.

The success of our drilling, manufacturing and aviation operations depends upon
the condition of the oil and gas industry, particularly the level of offshore
drilling activity. Demand for our offshore drilling and related services is
vulnerable to periodic declines in drilling activity typically associated with
depressed oil and natural gas prices. Oil and natural gas prices have
historically been volatile, and the offshore drilling market was generally
depressed from the early 1980s until the mid-1990s.

While the drilling industry benefited from increasing oil and natural gas prices
during most of the 1999-2000 period, it has never fully recovered from the
dramatic decline in prices during 1998 and the ensuing reduction in drilling
activity and day rates. Oil and natural gas prices increased steadily during
2000, but declined just as swiftly in 2001. Our drilling operations improved
over much of the 2000-2001 period, but deteriorated rapidly over the last half
of 2001. During 2002, oil and natural gas prices virtually doubled and,
throughout 2003 and early 2004, have generally remained at historically high
levels. However, demand for drilling services, particularly in our largest
market, the Gulf of Mexico, remains well below peak 2000-2001 levels, and our
drilling operating results in 2002 and the first half of 2003 were generally
unfavorable. In early 2004, our rig utilization and average day rates have
declined and our drilling operations have been adversely impacted.

12


Demand for drilling services also depends on additional factors that are beyond
our control, including:

- fluctuations in the worldwide demand for oil and natural gas;

- the willingness and ability of the Organization of Petroleum Exporting
Countries, or OPEC, to limit production levels and influence prices;

- political and military conflicts in oil-producing areas and the
effects of terrorism; and

- the level of production in non-OPEC countries.

Our drilling and aviation operations will be adversely affected by future
declines in oil and natural gas prices, but we cannot predict the extent of that
effect. We also cannot assure you that a reduction in offshore drilling activity
will not occur for other reasons.

We have incurred losses recently and over prolonged periods in the past, a
circumstance that could occur again in the future.

In 2002, we experienced a 16% decline in revenues and incurred a net loss from
operations of $12.9 million due primarily to the rapid decline in oil and
natural gas prices in 2001, as discussed above. We incurred a $7.8 million net
loss in 2003 and anticipate a net loss during the first quarter of 2004.

Our markets remain highly competitive, which may cause us difficulty in
differentiating our products and services and maintaining satisfactory price
levels.

The drilling, manufacturing and aviation markets are highly competitive, and no
single competitor is dominant. In the drilling market, a general oversupply of
rigs has lasted for well over a decade, and we believe that competition for
drilling contracts will continue to be intense for the foreseeable future.
Changes in drilling technology or in our competitors' rig fleets could affect
our ability to compete in this market. The aviation and manufacturing markets
are also characterized by vigorous competition among several competitors. Some
of our competitors possess greater financial resources than we do.

Our fleet expansion program may encounter liquidity problems.

If the operating conditions we experienced in 2002, the first half of 2003 and
early 2004 continue for a prolonged period, our results of operations and
working capital may not be adequate to finance our fleet expansion program, and
outside financing may not be available. We would be forced to suspend our
construction program.

We have in progress an offshore fleet expansion program under which we could
spend more than $280 million over the 2004-2006 period towards the completion of
the first two Tarzan Class jack-up rigs and, subject to final approval by our
Board of Directors, the construction of two additional Tarzan Class rigs, of
which only about $90 million is financed at this time. In addition, we expect to
spend another $40-50 million annually over this period for upgrades to existing
equipment and facilities and additional aircraft. We currently have no other
available lines of credit. Thus, much of our expected capital expenditures over
the 2004-2006 period will need to be financed from working capital or results of
operations. If we experience cost overruns or delays in our capital projects or
if we should need additional financing and are unable to obtain it at
commercially favorable rates, we could experience liquidity problems.

13


Our results of operations will be adversely affected if we are unable to secure
drilling contracts for our rigs on economically favorable terms.

The drilling markets in which we compete frequently experience significant
fluctuations in the demand for drilling services, as measured by the level of
exploration and development expenditures, and the supply of capable drilling
equipment. In response to fluctuating market conditions, we can, as we have done
in the past, relocate drilling rigs from one geographic area to another, but
only when such moves are economically justified over the longer term. If demand
for our rigs declines, our rig utilization and day rates are generally adversely
affected.

The addition to our available drilling fleet of the Scooter Yeargain in 2004 and
the Bob Keller in 2005 will, in each case, significantly increase our daily
operating costs. Neither rig has been contracted at this time, and day rates for
comparable rigs have, at many times over the past several years, only slightly
exceeded the expected daily operating costs of the Tarzan Class rigs. We may be
unable to secure economical drilling contracts for the rigs, in which case their
delivery will negatively impact our operating results.

We are subject to operating risks such as blowouts and well fires that could
result in environmental damage, property loss, personal injury and death.

Our drilling operations are subject to many hazards that could increase the
likelihood of accidents. Accidents can result in:

- costly delays or cancellations of drilling operations;

- serious damage to or destruction of equipment;

- personal injury or death;

- significant impairment of producing wells, leased properties or
underground geological formations; and

- major environmental damage.

Our offshore drilling operations are also subject to marine hazards, either at
offshore sites or while drilling equipment is under tow, such as vessel
capsizings, collisions or groundings. In addition, raising and lowering jack-up
rigs, an offshore drilling platform whose three legs independently penetrate the
ocean floor, flooding semi-submersible ballast tanks to help fix the floating
drilling unit over a well site and drilling into high-pressure formations are
complex, hazardous activities and we frequently encounter problems.

Our manufacturing and aviation operations also present serious risks. Our
manufacturing processes could pollute the air, land and inland waters, and the
products we manufacture could be implicated in lawsuits alleging environmental
harm, property loss, personal injury and death. Operating helicopters and
fixed-wing aircraft is similarly hazardous, particularly in Alaska where weather
conditions can be severe.

We have had accidents in the past demonstrating some of the hazards described
above, including high pressure drilling accidents resulting in lost or damaged
drilling formations, towing accidents resulting in lost drilling equipment and
flying accidents resulting in lost aircraft and deaths. Because of the ongoing
hazards associated with our operations:

- we may experience a higher number of accidents in the future than
expected;

- our insurance coverage may prove inadequate to cover losses that are
greater than anticipated;

- our insurance deductibles may increase; or

- our insurance premiums may increase to the point where maintaining our
current level of coverage is prohibitively expensive.

Any similar events could yield future operating losses and have a significant
adverse impact on our business.

14


Government regulations and environmental risks, which reduce our business
opportunities and increase our operating costs, might worsen in the future.

Government regulations dictate design and operating criteria for drilling
vessels and aircraft, determine taxation levels to which we (and our customers)
are subject, control and often limit access to potential markets and impose
extensive requirements concerning employee safety, environmental protection and
pollution control. Environmental regulations, in particular, prohibit access to
some markets and make others less economical, increase equipment and personnel
costs and often impose liability without regard to negligence or fault. In
addition, governmental regulations may discourage our customers' activities,
reducing demand for our products and services. We may be liable for damages
resulting from pollution of offshore waters and, under United States
regulations, must establish financial responsibility in order to drill offshore.

Anti-takeover provisions in our Certificate of Incorporation, bylaws and
stockholder rights plan could make it difficult for holders of our common stock
to receive a premium for their shares upon a change of control.

Holders of the common stock of acquisition targets may receive a premium for
their shares upon a change of control. Delaware law and the following
provisions, among others, of our Certificate of Incorporation, bylaws and rights
plan could have the effect of delaying or preventing a change of control and
could prevent holders of our common stock from receiving such a premium:

- The affirmative vote of 80% of the outstanding shares of our capital
stock is required to approve business combinations with any related
person that have not been approved by our board of directors. We are
also subject to a provision of Delaware corporate law that prohibits
us from engaging in a business combination with any interested
stockholder for three years from the date that person became an
interested stockholder unless specified conditions are met.

- Special meetings of stockholders may not be called by anyone other
than our board of directors, its chairman, its executive committee or
our president or chief executive officer.

- Our board of directors is divided into three classes whose terms end
in successive years, so that less than a majority of our board comes
up for election at any annual meeting.

- Our board of directors has the authority to issue up to 5,000,000
shares of preferred stock and to determine the voting rights and other
privileges of these shares without any vote or action by our
stockholders.

- We have adopted a stockholder rights plan that provides our
stockholders rights to purchase junior preferred stock in certain
circumstances, whereby the ownership of Rowan shares by a potential
acquirer can be significantly diluted by the sale at a significant
discount of additional Rowan shares to all other stockholders, which
could discourage unsolicited acquisition proposals.

ITEM 2. PROPERTIES

Rowan leases as its corporate headquarters 59,600 square feet of space in an
office tower located at 2800 Post Oak Boulevard in Houston, Texas.

facility with 19,000 square feet near Aberdeen, Scotland.

MANUFACTURING FACILITIES

LeTourneau's principal manufacturing facility and headquarters are located in
Longview, Texas on approximately 2,400 acres with approximately 1.2 million
square feet of covered working area. The facility contains:

- a mini-steel mill with 330,000 square feet of covered working area;
the mill has two 25-ton electric arc furnaces capable of producing
120,000 tons per year;

For the purposes of complying with the amendments to the rules governing
Form S-8 (effective July 13, 1990) under the Securities Act of 1933, the
undersigned registrant hereby undertakes as follows, which undertaking
shall be incorporated by reference into Registrant's Registration
Statements on Form S-8 Nos. 2-58700, as amended by Post-Effective Amendment
No. 4 (filed June 11, 1980), 33-33755, as amended by Amendment No. 1 (filed
March 29, 1990), 33-61444 (filed April 23, 1993), 33-51103 (filed November
18, 1993), 33-51105 (filed November 18, 1993), 33-51109 (filed November 18,
1993), 333-25041 (filed April 11, 1997), 333-25125 (filed April 14, 1997),
333-84369 (filed August 3, 1999), 333-84405 (filed August 3, 1999) and
333-101914 (filed December 17, 2002):

Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers
and controlling persons of the Registrant pursuant to the
foregoing provisions, or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as
expressed in the Securities Act of 1933 and is, therefore,
unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director,
officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question
whether such indemnification by it is against public policy as
expressed in the act and will be governed by the final
adjudication of such issue.
