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 2002, 2001 and
2000 is incorporated herein by reference from Footnote 10 of the Notes to
Consolidated Financial Statements on pages 36 and 37 of Rowan's 2002 Annual
Report to Stockholders ("Annual Report"), incorporated portions of which are
filed as Exhibit 13 hereto.

During 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. In 2000, 11% of Rowan's consolidated revenues
were derived from The Coastal Corporation, primarily from drilling services.


DRILLING OPERATIONS

Rowan provides contract drilling services utilizing a fleet of 22
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 2002,
drilling operations incurred an operating loss (loss from operations before
deducting general and administrative expenses) of $2.4 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 30,000 feet in maximum water depths ranging
from 250 to 490 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 27, 2003, Rowan's offshore drilling fleet included the following:

o 15 cantilever jack-up rigs, featuring three harsh environment
"Gorilla class" rigs and three enhanced "Super Gorilla class" rigs
o seven conventional jack-up rigs, including five rigs with skid base
capability
o one semi-submersible rig

The fleet declined to 23 units following the loss in October 2002 of the
Rowan-Houston during Hurricane Lili. The Company operates two of the cantilever
jack-up rigs under operating leases expiring in 2008.

Rowan's Gorilla class rigs, Gorillas II, III and IV, are a heavier-duty class
of jack-up rig, intended to drill up to 30,000 feet 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.

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 during June 2000, and Rowan Gorilla VII was delivered during 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.

To date, Rowan has assembled a significant portion of the Bob Palmer (formerly
Gorilla VIII), an enhanced version of the Super Gorilla class jack-up
designated as Super Gorilla XL. The Bob Palmer will be outfitted with 708 feet
of leg, 134 feet more than Gorillas V, VI or VII, and have 30% larger spud
cans, enabling operation in the Gulf of Mexico in water depths up to 550 feet.
The Bob Palmer will also be able to operate in water depths up to 400 feet in
the hostile environments offshore eastern Canada and in the North Sea. The Bob
Palmer is being constructed at Vicksburg, Mississippi with delivery expected
during the third quarter of 2003. Rowan obtained Title XI bank financing for up
to $187.3 million of the cost of the Bob Palmer in May 2001, under terms and
conditions similar to those in effect for Gorilla VII.

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 outer continental shelf in the
Gulf of Mexico. 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
about one-third of the construction cost. The first of as many as four new
Tarzan rigs, named the Scooter Yeargain, is under construction at Vicksburg,
Mississippi, with delivery expected during mid-year 2004. Rowan recently
received a commitment for Title XI bank financing for up to 87.5% of the cost
of the first two Tarzan rigs, under terms and conditions similar to those in
effect for the Bob Palmer, and intends to apply for Title XI financing for
Tarzans III and IV.

This fleet expansion program began in 1995 and represents Rowan's first new
construction since the mid-1980s. Since that time, Rowan's capital expenditures
have been primarily for enhancements to existing drilling rigs and
manufacturing

2

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 class 116-C jack-up rigs;
adding one to two engines to six of the class 116-C rigs, each such rig now
being equipped with six engines; installing new generation top-drives on four
of the class 116-C rigs and one of the Gorilla class rigs; upgrading the
electrical systems on one of the class 84 rigs; adding leg length to three of
the class 116-C rigs and reconditioning the subsea equipment on the
semi-submersible rig.

For a further discussion of Rowan's availability of funds in 2003 to sustain
operations, debt service and planned capital expenditures, including those
related to construction of the Bob Palmer and the Scooter Yeargain, see
"Liquidity and Capital Resources" under "Management's Discussion and Analysis
of Financial Condition and Results of Operations" on pages 19 through 21 of the
Annual Report, which information is incorporated herein by reference. Also, see
ITEM 2. PROPERTIES beginning on page 14 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 and 2005 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: nine in Texas and nine in Louisiana.
The fleet features four newly constructed rigs and seven rigs that have been
substantially rebuilt over the past three years, including four rigs relocated
from Alaska during the period.

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.

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

3

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 14 of this Form 10-K for the contract status of the Company's rigs as
of March 27, 2003.

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 with more than
500 available mobile rigs and approximately 20 domestic drilling contractors
with more than 200 available deep-well land rigs. 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.

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 27, 2003, Rowan had 20
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 third
largest

4

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. 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 21 of Rowan's 2002 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.

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.

5

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 22 operated by Rowan. In
2002, the manufacturing division generated an operating profit of $0.8 million.
External manufacturing backlog for all product lines was approximately $24
million at February 28, 2003, all of which is expected to be realized in 2003,
compared with $29 million at February 28, 2002, all of which was realized
during 2002.

The mining equipment product line features front-end loaders with bucket
capacities of 17, 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 solid-state 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 65 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.

6

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 21 parts-stocking
locations, and 30 independent international dealers and its own Australian
dealer with 45 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 775 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 is currently constructing for the Company a Super Gorilla XL
class jack-up rig and the first 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.

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.

7

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.

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.

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 eight jack-ups under construction worldwide, two of which
are LeTourneau 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

8

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 2003. Further regulations may reasonably be anticipated, but any effects
thereof on the Company's manufacturing operations cannot be accurately
predicted.

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 27, 2003 of 88 helicopters and 19 fixed-wing
aircraft. In 2002, the aviation division generated an operating profit of $13.8
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 2002,
the Alaska helicopter operations contributed approximately 25% of the Company's
aviation revenues.

9

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. Era's regional airline
is the largest airline operation of that type within the state of Alaska and is
the third largest carrier of passengers into and out of the Ted Stevens
Anchorage International Airport, including the large jet carriers. During 2002,
the commuter airline contributed approximately 25% of the Company's aviation
revenues.

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 2002, the Gulf of Mexico helicopter operations
contributed approximately 42% 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 delivered in the first half of 2004 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 27, 2003 consisted of 88 helicopters (including 42 based
in Alaska and 46 in the Gulf of Mexico area) and 19 fixed-wing aircraft (based
in Alaska). The fleet contract status at that date included 21 term contracts.
The

10

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.

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 5,237 employees at February 28, 2003 and 5,227, 4,943 and 4,917
employees at December 31, 2002, 2001 and 2000, 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 offshore 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

11

the 2000-2001 period, but deteriorated rapidly over the last half of 2001.
During 2002, oil and natural gas prices virtually doubled and are now near
record levels, though, as a result of this extreme price volatility in recent
years and the economic effects of 9/11, our drilling operations in 2002 never
attained peak 2000-2001 levels. In recent months, our rig utilization and
average day rates have declined and our drilling operations have been adversely
impacted.

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

o fluctuations in the worldwide demand for oil and natural gas;
o the willingness and ability of the Organization of Petroleum
Exporting Countries, or OPEC, to limit production levels and
influence prices;
o political and military conflicts in oil-producing areas and the
effects of terrorism; and
o 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. Our 2002 revenues and earnings were negatively
affected by lower rig day rates due to the rapid decline in oil and natural gas
prices in 2001 as discussed above. We anticipate an operating loss during the
first quarter of 2003.

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. 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 we continue to experience present operating conditions for a prolonged
period, our results of operations and working capital may not be adequate to
finance our planned construction 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
currently plan to spend more than $400 million over the 2003-2005 period
towards the completion of the Bob Palmer and for the construction of as many as
four Tarzan class jack-up rigs, of which only about $220 million is financed at
this time. In addition, we expect to spend another $50-75 million annually over
this period for upgrades to existing equipment and facilities and additional
land rigs and aircraft. We currently have no other available lines of credit.
Thus, much of our planned capital expenditures over the 2003-2005 period will
need to be financed from working capital or results of operations. If we should
need additional financing and are unable to obtain it at commercially favorable
rates, we could experience liquidity problems.

12

Our results of operations will be adversely affected if we are unable to secure
- -------------------------------------------------------------------------------
contracts for the Bob Palmer and the Scooter Yeargain.
- ------------------------------------------------------

The addition to our available drilling fleet of the Bob Palmer in late 2003 and
the Scooter Yeargain in mid-2004 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 Bob Palmer and the
Scooter Yeargain. 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:

o costly delays or cancellations of drilling operations;
o serious damage to or destruction of equipment;
o personal injury or death;
o significant impairment of producing wells, leased properties or
underground geological formations; and
o 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 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:

o we may experience a higher number of accidents in the future than
expected;
o our insurance coverage may prove inadequate to cover losses that are
greater than anticipated;
o our insurance deductibles may increase; or
o 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.

13

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 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 typically 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:

o The affirmative vote of 80% of the outstanding shares of our capital
stock is required to approve business combinations 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.

o Special meetings of stockholders may not be called by anyone other
than our chairman of the board, president, board of directors or the
executive committee thereof.

o 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.

o 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.

o We have issued "poison pill" rights to purchase junior preferred
stock under our rights plan, 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.

(b) Reports on Form 8-K:

No reports on Form 8-K were filed by the Registrant during the fourth
quarter of fiscal year 2002.

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

26

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.
