Items 1. and 2. BUSINESS AND PROPERTIES


A. GENERAL

During fiscal year 1995, McDermott International, Inc.  contributed
substantially all of its marine construction services business to J. Ray
McDermott, S.A. ("JRM"), a new company incorporated under the laws of the
Republic of Panama in 1994.  On January 31, 1995, JRM acquired Offshore
Pipelines, Inc. ("OPI") in a merger transaction (the "Merger"). Prior to the
Merger with OPI, JRM was a wholly owned subsidiary of McDermott International,
Inc.; as a result of the Merger, JRM is a majority owned subsidiary of McDermott
International, Inc.  JRM's Common Stock and 9.375% Senior Subordinated Notes due
July 2006 are publicly traded.

McDermott International, Inc. received as consideration for its contribution to
JRM: 3,200,000 shares of JRM Series A $2.25 Cumulative Convertible Preferred
Stock; $231,000,000 of  9% Senior Subordinated Notes due 2001; 24,668,297 shares
of JRM common stock; and other consideration. OPI investors received 13,867,946
shares of JRM common stock; options to acquire 897,818 shares of JRM common
stock and 458,632 shares of JRM Series B $2.25 Cumulative Convertible
Exchangeable Preferred Stock in exchange for all of the outstanding common
stock, common stock options and preferred stock of OPI. During fiscal year 1996,
458,382 shares of Series B Preferred Stock were converted into 1,065,193 shares
of common stock and the remaining 250 shares were redeemed for cash.  During
fiscal year 1997, the 9% Senior Subordinated Notes due 2001 held by McDermott
International, Inc. together with accrued interest were paid in full by JRM from
proceeds of a debt offering by JRM of $250,000,000 in principal amount of 9.375%
Senior Subordinated Notes due July 2006.

The discussion set forth below under Items 1. and 2., Business and Properties,
describes the business of JRM as currently conducted after the Merger.

Unless the context otherwise requires, hereinafter, "JRM" means J. Ray
McDermott, S.A. and its consolidated subsidiaries; "International" means
McDermott International, Inc., a Panama corporation that is the parent company
of the McDermott group of companies and the majority owner of JRM; and
"McDermott International" means the consolidated enterprise.

JRM, together with its subsidiaries and joint ventures, supplies worldwide
services for the offshore oil and gas exploration and production and hydrocarbon
processing industries, and to other marine construction companies.  Principal
activities include the design, engineering, fabrication and installation of
offshore drilling and production platforms and other specialized structures,
modular facilities, marine pipelines and subsea production systems.

JRM has a continuing program of reviewing joint venture, acquisition and
disposition opportunities.

B. DESCRIPTION OF OPERATIONS


GENERAL

JRM's services include the basic and detailed design, engineering, fabrication
and installation of offshore drilling and production platforms and other
specialized structures, modular facilities, marine pipelines, and subsea
production systems.  JRM also provides comprehensive project management
services, feasibility studies, engineering services, subsea trenching services,
diving services, procurement activities  and removal, salvage and refurbishment
services for offshore fixed platforms.  JRM and its joint ventures operate
throughout the world in all major offshore oil and gas producing regions,
including the Gulf of Mexico, the North Sea, West Africa, South America, the
Middle East, India and the Far East.

JRM conducts operations both directly and through its participation in joint
ventures, some of which it manages and others of which are managed by other
marine construction contractors.  Some of JRM's joint ventures are consolidated
for financial reporting purposes while others are accounted for using either the
equity or the cost method.  JRM's joint ventures are largely financed through
their own resources, including, in some cases, stand-alone borrowing
arrangements.  JRM's two most significant joint venture investments were in the
HeereMac joint venture, which was accounted for by the cost method, and the
McDermott-ETPM joint venture, which was comprised of several joint venture
operating companies, all of which were consolidated for financial reporting
purposes other than McDermott-ETPM West, Inc. which was accounted for by the
equity method.

On December 19, 1997, JRM and Heerema Offshore Construction Group, Inc.
("Heerema") terminated the HeereMac joint venture.  The HeereMac joint venture
was formed in January 1989 and utilized the specialized, heavy-lift marine
construction  vessels which were previously owned by the two parties.  Each
party had a 50% interest in the joint venture, and Heerema had responsibility
for its day-to-day operations.  Pursuant to the termination, Heerema acquired
and assumed JRM's 50% interest in the joint venture in exchange for cash of
$318,500,000 and title to several pieces of equipment.  The equipment
transferred to JRM includes two launch barges and the derrick barge 101, a 3,500
ton lift capacity, semi-submersible derrick barge.

JRM formed its initial joint venture with ETPM S.A., McDermott-ETPM, in April
1989 to provide general marine construction services to the petroleum industry
in West Africa, South America, the Middle East and India and offshore pipelaying
services in the North Sea.  With the addition of two new joint venture operating
companies in March 1995, JRM and ETPM S.A. expanded their joint venture's
operations to include the Far East and began jointly pursuing subsea contracting
work on a worldwide basis.  Most of the operating companies in the McDermott-
ETPM joint venture were majority-owned and controlled by JRM.  However, the
operations of McDermott-ETPM West, Inc., which conducts operations in the North
Sea, South America and West Africa, were managed and controlled by ETPM S.A.

On April 3, 1998, JRM and ETPM S.A. terminated the McDermott-ETPM joint venture.
Pursuant to the termination, JRM received net cash of approximately $105,000,000

<PAGE>
 
ETPM East, Inc. and McDermott-ETPM Far East, Inc. ETPM S.A. received the lay
barge 200 and took ownership of McDermott Subsea Constructors Limited ("MSCL")
and McDermott-ETPM West, Inc.

JRM participates in other joint ventures involving operations in foreign
countries that require majority-ownership by local interests.  Through a
subsidiary, JRM also participates in an equally owned joint venture with the
Brown & Root Energy Services unit of Halliburton Company ("Brown & Root"), which
was formed in February 1995 to combine the operations of JRM's Inverness and
Brown & Root's Nigg fabrication facilities in Scotland.

In May 1998, JRM sold its interest in McDermott Engineering (Europe) Limited and
announced its intention to exit other European engineering operations.  See Note
16 to the consolidated financial statements regarding these events.  These
actions leave only Mentor Subsea Technology Services, Ltd. to maintain JRM's
presence in the European subsea markets.

At March 31, 1998, JRM owned or operated 6 fabrication facilities throughout the
world.  JRM's principal domestic fabrication yard and offshore base is located
on 1,114 acres of land, under lease, near Morgan City, Louisiana.  JRM also owns
or operates fabrication facilities near Corpus Christi, Texas, near Inverness,
Scotland, in Indonesia on Batam Island, in Jebel Ali, U.A.E. and in Warri,
Nigeria.  JRM also owns and operates a ship repair and fabrication yard in
VeraCruz, Mexico.

JRM's fabrication facilities are equipped with a wide variety of heavy-duty
construction and fabrication equipment, including cranes, welding equipment,
machine tools and robotic and other automated equipment, most of which is
movable.  JRM has the capability to fabricate a full range of offshore
structures, from conventional jacket-type fixed platforms to deepwater platform
configurations employing compliant-tower, tension leg, floating production
platform and spar technology.  JRM also fabricates platform deck structures and
modular components, including complete production processing systems,
hydrocarbon separation and treatment systems, pressure and flow control systems
and personnel quarters.

At March 31, 1998, expiration dates, including renewal options, of leases
covering land for JRM's fabrication yards were as follows:

                 Morgan City, Louisiana       Years 2000-2033
                 Jebel Ali, U.A.E.            Year 2005
                 Batam Island, Indonesia      Year 2008
                 Warri, Nigeria               Year 2065
 
Pursuant to the termination of the McDermott-ETPM joint venture in April 1998,
ETPM S.A. acquired the fabrication facility located at Warri, Nigeria.

JRM owns or, through its ownership interests in joint ventures, has interests in
one of the largest fleets of marine equipment used in major offshore
construction.  The nucleus of a "construction spread" is a large derrick barge,
pipelaying barge or combination derrick-pipelaying barge capable of offshore
operations for an extended period of time in remote locations.  At March 31,
1998, JRM owned or, through ownership interests in joint ventures, had interests
in 5 derrick vessels, 4 pipelaying vessels, 9 combination derrick-pipelaying
vessels 

                                       3
<PAGE>
 
and 3 pipe burying vessels. The lifting capacities of the derrick and
combination derrick-pipelaying vessels range from 250 to 5,000 tons. These
vessels range in length from 400 to 698 feet and are fully equipped with stiff
leg or revolving cranes, auxiliary cranes, welding equipment, pile-driving
hammers, anchor winches and a variety of additional gear. The largest vessels
are the semi-submersible derrick barge 101, and the lay barge 200, a semi-
submersible pipelaying vessel. Pursuant to the termination of the McDermott-ETPM
joint venture, ETPM S.A. received the lay barge 200 and two other vessels owned
by MSCL and JRM received ETPM S.A.'s derrick/lay barge 1601. In addition,
subsequent to fiscal year end, JRM's Malaysian joint venture sold two
combination derrick-pipelaying vessels and JRM sold two pipe burying vessels.

To support the operations of these major marine construction vessels, JRM and
its joint ventures also own or lease a substantial number of other vessels, such
as tugboats, utility boats, launch barges and cargo barges.   In connection with
its construction and pipelaying activities, JRM conducts diving operations
which, because of the water depths involved, require sophisticated equipment,
including diving bells and an underwater habitat.


FOREIGN OPERATIONS

The amount of JRM's revenues and segment income derived from operations located
outside of the United States, and the approximate percentages to JRM's total
revenues and total segment income, respectively, follow:

 
                         REVENUES             SEGMENT INCOME
  FISCAL YEAR       AMOUNT      PERCENT     AMOUNT    PERCENT
                                   (Dollars in thousands)
 
     1998        $ 1,122,084      60%     $317,482      231%

     1997            852,062      60%       14,525      45%
 
     1996            855,244      68%       16,883      35%
 

RAW MATERIALS

The raw materials used by JRM, such as carbon and alloy steel in various forms,
welding gases, concrete, fuel oil and gasoline, are available from many sources
and JRM is not dependent upon any single supplier or source.  Although shortages
of certain of these raw materials and fuels have existed from time to time, no
serious shortage exists at the present time.


CUSTOMERS AND COMPETITION

JRM's principal customers are oil and gas companies, including foreign
government owned companies.  Customers generally contract with JRM for the
design, engineering, fabrication and installation of offshore drilling and
production platforms and other specialized structures, modular facilities,
marine pipelines and subsea production systems.  Contracts are usually awarded
on a competitive bid basis.  There are a number of companies which compete
effectively with JRM and its joint ventures in each of the separate marine
construction phases in various parts of the world.

                                       4

BACKLOG

As of March 31, 1998 and 1997, JRM's backlog amounted to $1,267,148,000 and
$1,776,663,000, respectively. Backlog decreased primarily as a result of a
decline in engineering, procurement and construction activities in the Middle
East, procurement activities in the Far East, engineering activities in the
North Sea and management's focus on higher margin projects.  Of the March 31,
1998 backlog, management expects that approximately $942,077,000 will be
recognized in revenues in fiscal year 1999, $225,602,000 in fiscal year 2000
and $99,469,000 thereafter.

During fiscal year 1998, JRM received contract awards valued at $50,000,000 from
British-Borneo Exploration, Inc. for work on the Morpeth Field Development in
the Gulf of Mexico.  Under the contract, JRM will transport and install a
SeaStar mini-tension leg platform and associated pipelines at Ewing Banks Block
921 in 1,670 feet of water.  JRM also has the responsibility for subsea system
design, procurement and commissioning through its subsidiary Mentor Subsea
Technology Services, Ltd.  JRM will also install 21 miles of 8-inch and 12-inch
diameter pipeline utilizing conventional S-lay technology.  The installation
will be complete in the summer of 1998.  JRM has also been awarded a contract
from Shell Offshore Inc., valued at approximately $25,000,000, for construction
of a fixed-base platform for an offshore development in the Gulf of Mexico.  The
platform is being designed by JRM under a separate contract with Shell.  The
installation will take place in July 1998 and the lift will be the heaviest to
date in the Gulf of Mexico.  When complete, this platform will be the world's
deepest tripod, standing 750 feet above the floor of the Gulf of Mexico.
Backlog also includes a $112,300,000 contract attributable to an agreement with
a customer for exclusive use of a company vessel over a two-year period.  As of
March 31, 1998, the customer could release the vessel to the company for a
stand-by payment of $16,200,000.  In management's opinion, the vessel will be
utilized at levels to achieve the backlog amount.

Not included in backlog at March 31, 1998, is a $70,000,000 contract awarded in
May 1998 from British-Borneo Exploration, Inc., for work on the Allegheny field
development in the Gulf of Mexico.  Under the contract, JRM will transport and
install the hull, deck, pilings and tendons for a SeaStar mini-tension leg
platform in 3,300 feet of water.  JRM will also design steel catenary risers
("SCRs") and design, procure and commission five subsea completions and two
riser-end manifolds.  In addition, the contract includes the installation of two
12-inch diameter export pipeline SCRs and six miles of interfield flowlines and
associated SCRs.  The work is scheduled for completion in the summer of 1999.

Not included in JRM's backlog at March 31, 1998 and 1997 was backlog relating to
contracts to be performed by unconsolidated joint ventures of approximately
$587,000,000 (excluding  McDermott-ETPM West, Inc.) and $1,426,000,000,
respectively.  Included in the 1997 backlog was $645,000,000 and $300,000,000
related to the HeereMac and McDermott-ETPM West, Inc. joint ventures,
respectively.

Work has historically been performed on a fixed-price, cost-plus or day-rate
basis or a combination thereof.  More recently, certain "partnering type"
contracts have introduced a risk and reward element wherein a portion of total
compensation is tied to the overall performance of the alliance partners.  JRM
attempts to cover increased costs of anticipated changes in labor, material and
service costs of long-term contracts either through an estimate of such changes,

                                       5
<PAGE>
 
which is reflected in the original price, or through price escalation clauses.
Most long-term contracts have provisions for progress payments.

FACTORS AFFECTING DEMAND

The activity of JRM depends mainly on the capital expenditures of oil and gas
companies and foreign governments for developmental construction.  These
expenditures are influenced by the selling price of oil and gas along with the
cost of production and delivery, the terms and conditions of offshore leases,
the discovery rates of new reserves offshore, the ability of the oil and gas
industry to raise capital, and local and international political and economic
conditions.  In some Far East countries, internal consumption of oil and gas
products has decreased due to the current economic crisis.

Oil and gas company capital exploration and production budgets for calendar year
1998 were projected to increase for the fourth consecutive year to the highest
level in the past ten years but may now be curtailed by falling oil and gas
prices.  Increased production and lower worldwide demand for petroleum products
has led to a significant drop in oil prices and downward pressure on natural gas
prices.  Economic and political instability in Indonesia and political turmoil
on the Indian subcontinent are expected to have an adverse effect on exploration
and production spending.  Worldwide demand for offshore drilling rigs,
particularly for deepwater exploration, has remained strong and this,
historically, has been a leading indicator for an increase in the need for
marine construction services.  JRM's markets are expected to continue to emerge
from the competitive environment that has put pressure on margins in prior
periods.

C.   PATENTS AND LICENSES

JRM owns or has exclusive rights to use, for marine construction purposes, a
number of patents relating to offshore platform design, fabrication and
installation and pipelaying operations.  JRM also co-owns several other patents
relating to such operations.  Although in the aggregate these patents are
important to JRM, JRM does not consider any single patent to be of a critical or
essential nature.  In general, JRM depends on its technological capabilities and
the application of know-how as well as patents in the conduct of its business.

D.   INSURANCE

JRM maintains liability and property insurance against such risk and in such
amounts as it considers adequate.  However, certain risks are either not
insurable or insurance is available only at rates which JRM considers
uneconomical.  Among such risks are war and confiscation of property in certain
areas of the world and pollution liability in excess of relatively low limits.
Depending on competitive conditions and other factors, JRM endeavors to obtain
contractual protection against uninsured risks from its customers.  However,
there is no assurance that insurance or contractual indemnity protection, when
obtained, will be sufficient or effective under all circumstances or against all
hazards to which JRM may be subject.

JRM's offshore construction business is subject to the usual risks of operations
at sea, with additional exposure due to the utilization of expensive
construction equipment, sometimes under extreme weather conditions, often in
remote areas of the world.  In addition, JRM 

                                       6
<PAGE>
 
operates in many cases on or in proximity to existing offshore facilities which
are subject to damage by JRM and such damage could result in the escape of oil
and gas into the sea.

E.   EMPLOYEES

At March 31, 1998, JRM employed, under its direct supervision, approximately
11,700 persons compared with 11,600 at March 31, 1997.  Approximately 700
employees were members of labor unions at March 31, 1998 compared with 500 at
March 31, 1997. JRM considers its relationship with its employees to be
satisfactory.

F.   ENVIRONMENTAL REGULATIONS AND MATTERS

JRM is subject to the existing and evolving standards relating to the
environment.  These laws include the Comprehensive Environmental Response,
Compensation, and Liability Act of 1980 and similar laws which provide for
responses to and liability for releases of hazardous substances into the
environment; and the Clean Air Act, the Clean Water Act, the Resource
Conservation and Recovery Act and other federal laws, each as amended, and
similar foreign, state or local counterparts to these federal laws, which
regulate air emissions, water discharges, hazardous substances and wastes, and
require public disclosure related to the use of various hazardous substances.
JRM's operations are also governed by laws and regulations relating to workplace
safety and worker health, primarily Occupational Safety and Health Act and
regulations promulgated thereunder.  JRM believes that its facilities are in
substantial compliance with current regulatory standards.

JRM's compliance with U.S. federal, state and local environmental control and
protection regulations did not necessitate any capital expenditures in fiscal
year 1998, and management expects such capital expenditures will not be material
for the foreseeable future.   Management cannot predict all of the environmental
requirements or circumstances which will exist in the future, but anticipates
that environmental control and protection standards will become increasingly
stringent and costly.  Complying with existing environmental regulations
resulted in pretax charges  of approximately $1,443,000 in fiscal year 1998.

Compliance with existing government regulations controlling the discharge of
materials into the environment, or otherwise relating to the protection of the
environment does not have, nor does management expect it to have, a material
adverse effect upon JRM's consolidated financial position or results of
operations.

G.   TRANSACTIONS WITH RELATED PARTIES

JRM has material transactions occurring during the normal course of operations
with McDermott International and other affiliated companies. JRM has also
entered into various agreements with International and its subsidiaries. (See
Note 5 to the consolidated financial statements.)

While JRM's employee liability, comprehensive, general liability, property,
marine and other insurance programs are placed through commercial insurance
carriers, substantially all of such employee liability exposure is reinsured,
and significant deductibles under JRM's other insurance programs are insured, by
wholly owned insurance subsidiaries of McDermott International. The premiums
charged by such insurance companies of McDermott International for such
insurance 

                                       7
<PAGE>
 
are based upon the claims experience and forecasted activities of JRM and its
subsidiaries. Management believes this approach is more cost effective as there
is generally no commercial market for insurance on the same economic terms for
these types of exposure.

Item 3.   LEGAL PROCEEDINGS

In March 1997, JRM and International, with the help of outside counsel, began an
investigation into allegations of wrongdoing by a limited number of former
employees of JRM and International and others.  The allegations concerned the
heavy-lift business of the HeereMac joint venture.  Upon becoming aware of these
allegations, JRM and International notified authorities, including the Antitrust
Division of the U.S. Department of Justice and the European Commission.  As a
result of JRM's and International's prompt disclosure of the allegations, both
companies and the individuals who were officers, directors and employees of JRM
or International at the time of the disclosure were granted immunity from
criminal prosecution by the Department of Justice for any anti-competitive acts
involving worldwide heavy-lift activities.

After receiving the allegations, JRM initiated action to terminate its interest
in HeereMac, and on December 19, 1997, JRM's partner in the joint venture,
Heerema Offshore Construction Group, Inc. ("Heerema"), acquired JRM's interest
in exchange for $318,500,000 in cash and title to several pieces of equipment,
including launch barges and the derrick barge 101, a 3,500 ton lift capacity
semi-submersible derrick barge.  On December 21, 1997, HeereMac and a HeereMac
employee pled guilty to criminal charges by the Department of Justice that they
and others had participated in a conspiracy to rig bids in connection with the
heavy-lift business of HeereMac in the Gulf of Mexico, North Sea and Far East.
HeereMac was fined $49,000,000 and the employee $100,000.  As part of the plea,
both HeereMac and certain employees of HeereMac agreed to cooperate fully with
the Department of Justice investigation.  Neither JRM, International nor any of
their officers, directors or employees was a party to those proceedings.

JRM and International have cooperated and are continuing to cooperate with the
Department of Justice in its investigation.  Near the end of calendar 1997, the
Department of Justice requested additional information from the companies
relating to possible anti-competitive activity in the marine construction
business of McDermott-ETPM East, Inc., one of the operating companies within
JRM's former McDermott-ETPM joint venture with ETPM S.A., a French company.
Pursuant to the termination of the McDermott-ETPM joint venture on April 3,
1998, JRM assumed 100% ownership of McDermott-ETPM East, Inc., which has been
renamed J. Ray McDermott Middle East, Inc.

JRM and International are also cooperating with the Securities and Exchange
Commission ("SEC"), which also requested information and documents from the
companies with respect to certain of the foregoing matters. JRM and
International are subject to a judicial order entered  in 1976, with the consent
of McDermott Incorporated (which at that time was the parent of the McDermott
group of companies), pursuant to an SEC complaint ("Consent Decree").  The
Consent Decree prohibits the companies from making false entries in their books,
maintaining secret or unrecorded funds or using corporate funds for unlawful
purposes.  Violations of the Consent Decree could result in substantial civil
and/or criminal penalties to the companies.

In June 1998, Phillips Petroleum Company (individually and on behalf of certain
co-venturers) and certain related entities  filed a complaint in the United
States District Court for the Southern District of Texas against JRM,
International, McDermott Incorporated, McDermott-ETPM, Inc., 

                                       8
<PAGE>
 
certain JRM subsidiaries, HeereMac, Heerema, certain Heerema affiliates, and
others. The complaint alleges that the defendants engaged in anti-competitive
acts in violation of Sections 1 and 2 of the Sherman Act and Sections 15.05(a)
and (b) of the Texas Business and Commerce Code, engaged in fraudulent activity
and tortiously interfered with the plaintiffs' businesses in connection with
certain offshore transportation and installation projects in the Gulf of Mexico,
North Sea and Far East. In addition to seeking actual damages and attorneys'
fees, the plaintiffs have requested punitive as well as treble damages.

It is not possible to predict the ultimate outcome of the Department of Justice
investigation,  the SEC inquiry, the companies' internal investigation, the
above referenced lawsuit, or the actions that may be taken by others as a result
of HeereMac's guilty plea or otherwise.  However, these matters could result in
civil and/or criminal liability and have a material adverse effect on JRM's
consolidated financial position and results of operations.

In addition to the foregoing, due to the nature of its business, JRM is, from
time to time, involved in routine litigation related to its business activity.
It is management's opinion that none of this litigation will have a material
adverse effect on JRM's consolidated financial position or results of
operations.

Item 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matter was submitted during the fourth quarter of the fiscal year covered by
this report to a vote of security holders, through the solicitation of proxies
or otherwise.

JRM has never paid any dividends on its Common Stock, and management does not
anticipate any such dividends will be paid for the foreseeable future. As of
March 31, 1998, the approximate number of record holders of Common Stock was
577.

See Note 17 to the consolidated financial statements for significant items
included in fiscal year 1998 and 1997 results.  See Note 2 regarding
acquisitions in fiscal year 1998 accounted for in a manner similar to a pooling
of interests.  Earnings per share for the previous periods presented have been
restated due to the adoption of Statement of Financial Accounting Standards

the consolidated financial statements regarding the change to the cost method of
accounting for JRM's investment in the HeereMac joint venture in fiscal year
1997.  Equity income of HeereMac was $1,083,000, $6,244,000, and $79,386,000 in
fiscal years 1996, 1995, and 1994, respectively.  See Note 3 regarding the April
3, 1998 termination of the McDermott-ETPM joint venture.  Fiscal year 1995
includes the cumulative effect of the adoption of SFAS No. 112.  See Note 11
regarding the uncertainty as to the results of the ongoing investigation by JRM,
International and the U.S. Department of Justice into possible anti-competitive
practices by JRM and International, and a related lawsuit filed in federal court
on June 1, 1998.

JRM was incorporated on March 22, 1994 in the Republic of Panama and had no
significant operations prior to January 31, 1995 when International contributed
substantially all of its marine construction services business to JRM and JRM
acquired OPI.  The contribution of International's marine construction services
business to JRM was accounted for in a manner similar to a pooling of interests.
For the period prior to the contribution, JRM's results of operations include
charges from International for direct costs and allocations of corporate

                                       11
<PAGE>
 
overhead and other costs. Management believes that the allocation methods were
reasonable and that the allocations were representative of what the costs would
have been on a stand alone basis.

Earnings per Common Share are not presented for fiscal years 1994 and 1995
because JRM was not a separate entity with its own capital structure during
those periods.

Item 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION  AND
          RESULTS OF OPERATIONS

GENERAL

Revenues of JRM are largely a function of the level of oil and gas development
activity in the world's major hydrocarbon producing regions.  In general, JRM's
business is capital intensive and relies on large contracts for a substantial
amount of its revenues. Consequently, revenues reflect the variability
associated with the timing of significant development projects.  During fiscal
year 1998, U.S. and North Sea markets remained steady while Far East and Middle
East markets started to weaken.  Economic and political instability in Indonesia
and political turmoil on the Indian subcontinent are also expected to have an
adverse effect on exploration and production spending.

A significant portion of JRM's revenues and operating results are derived from
its foreign operations.  As a result, JRM's operations and financial results are
affected by international factors, such as changes in foreign currency exchange
rates.  JRM attempts to minimize its exposure to changes in foreign currency
exchange rates by attempting to match foreign currency contract receipts with
like foreign currency disbursements. To the extent that it is unable to match
the foreign currency receipts and disbursements related to its contracts, its
practice of entering into forward exchange contracts to hedge foreign currency
transactions reduces the impact of foreign exchange rate movements on operating
results.

Statements made herein which express a belief, expectation or intention, as well
as those which are not historical fact, are forward looking.  They involve a
number of risks and uncertainties which may cause actual results to differ
materially from such forward looking statements.  These risks and uncertainties
include, but are not limited to: decisions about offshore developments to be
made by oil and gas companies; the highly competitive nature of the marine
construction services business; operating risks associated with the marine
construction services business; economic and political instability in Indonesia;
political turmoil on the Indian subcontinent;  and the results of the ongoing
investigation by JRM and International and the U.S. Department of Justice into
possible anti-competitive practices by JRM and International, and a related
lawsuit filed in federal court in June 1998.

FISCAL YEAR 1998 VS FISCAL YEAR 1997

Revenues increased $447,017,000 to $1,855,486,000, primarily due to higher
volume in virtually all activities in all operating areas, except in offshore
activities in the Far East, engineering activities in the Middle East and
engineering and procurement activities in Europe and West Africa.

                                       12
<PAGE>
 
Segment operating income increased $96,303,000 to $107,122,000. Virtually all
activities in all operating areas, except the Far East and Engineering,
reflected this increase.

Gain (loss) on asset disposals and impairments-net decreased $69,140,000 from a
gain of $29,021,000 to a loss of $40,119,000, primarily due to the impairment
loss of $262,901,000 relating to goodwill associated with the acquisition of
OPI.  Prior year gains from the sale of the derrick barges 15 and 21,
participation in a gain from the sale of the derrick barge 100 by the HeereMac
joint venture and the realization of a portion of the deferred gain resulting
from the sale of the derrick barges 101 and 102 also contributed to the
decrease.  These decreases were partially offset by the $224,472,000 gain
recognized from the termination of the HeereMac joint venture.

Income (loss) from investees increased $78,069,000 from a loss of $7,833,000 to
income of $70,236,000, primarily due to a $61,637,000 distribution of earnings
related to the termination of the HeereMac joint venture.  Equity in loss from
the McDermott-ETPM West, Inc. joint venture decreased $9,248,000 to a loss of
$7,584,000 in fiscal year 1998.

See Note 3 to the consolidated financial statements regarding the April 3, 1998
termination of the McDermott-ETPM joint venture.  See Note 16 to the
consolidated financial statements regarding the sale and intention to exit
certain European operations.

Backlog at March 31, 1998 and 1997 was $1,267,148,000 and $1,776,663,000,
respectively.  Backlog decreased primarily as a result of a decline in
engineering, procurement and construction activities in the Middle East,
procurement activities in the Far East, engineering activities in the North Sea
and management's focus on higher margin projects.  Not included in backlog at
March 31, 1998 and 1997 was backlog relating to contracts to be performed by its
unconsolidated joint ventures of approximately $587,000,000 (excluding
McDermott-ETPM West, Inc.) and $1,426,000,000, respectively.  Included in the
1997 backlog was $645,000,000 and $300,000,000 related to the HeereMac and
McDermott-ETPM West, Inc. joint ventures, respectively.

General corporate expenses decreased $3,546,000 to $13,064,000, primarily due to
certain one-time costs incurred in the prior period.

Interest income increased $9,694,000 to $26,252,000, primarily due to increases
in cash equivalents, investments in government obligations and other debt
securities.

Interest expense decreased $10,785,000 to $30,793,000, primarily due to changes
in debt obligations and interest rates prevailing thereon.

Other-net income decreased $4,278,000 to $4,177,000, primarily due to a decrease
in certain reimbursed financing costs and minority shareholder participation in
the improved results of MSCL.  These decreases were partially offset by higher
foreign currency transaction gains in the current year.

The provision for income taxes increased $23,119,000 to $34,851,000 while income
(loss) before the provision for income taxes increased $124,979,000 to income of
$123,811,000 from a loss of $1,168,000.  The increase in income taxes is
primarily due to an increase in income.  In addition, JRM operates in many
different tax jurisdictions.  Within these jurisdictions, tax provisions vary
because of nominal rates, allowability of deductions, 

                                       13
<PAGE>
 
credits and other benefits, and even tax basis (for example, revenue versus
income). These variances, along with variances in the mix of income within
jurisdictions, are responsible for shifts in the effective tax rate.

FISCAL YEAR 1997 VS FISCAL YEAR 1996

Revenues increased $149,018,000 to $1,408,469,000, primarily due to higher
volume in virtually all activities in all operating areas, except in fabrication
activities in the Far East and all activities in Europe and West Africa.

Segment operating income decreased $26,095,000 to $10,819,000.  The decrease was
primarily due to lower volume in Europe and West Africa and lower margins in the
Far East.  These decreases were partially offset by higher volume in North
American Operations and in the Middle East.  In addition, there were higher net
operating expenses.

Gain on asset disposals and impairments-net increased $26,491,000 to
$29,021,000, primarily due to gains from the sale of the derrick barges 15 and
21, participation in a gain from the sale of the derrick barge 100 by the
HeereMac joint venture and the realization of a portion of the deferred gain
resulting from the sale of the derrick barges 101 and 102.  These increases were
partially offset by certain asset write-downs.

Income (loss) of investees decreased $16,957,000 from income of $9,124,000 to a
loss of $7,833,000. This decrease was primarily due to lower results from the
McDermott-ETPM West, Inc. joint venture.  Revenues of the McDermott-ETPM West,
Inc. joint venture increased $97,207,000 to $347,849,000 in fiscal year 1997,
primarily due to increased volume in the North Sea and West Africa.  Equity in
Income (loss) from this joint venture decreased $19,366,000 to a loss of
$16,833,000 in fiscal year 1997, primarily due to lower margins in West Africa.
These decreases were partially offset by favorable results from a Mexican joint
venture.

General corporate expenses increased $4,596,000 to $16,610,000, primarily due to
certain one-time costs incurred in the current period.

Interest income increased $10,466,000 to $16,558,000, primarily due to interest
on the promissory note received as part of the consideration from the sale of
the derrick barge 101 and derrick barge 102.

Interest expense decreased $1,729,000 to $41,578,000, primarily due to changes
in debt obligations and interest rates prevailing thereon.

Other-net income increased $3,397,000 to $8,455,000, primarily due to foreign
currency transaction gains in the current year compared to foreign currency
transaction losses in the prior year.

The provision for income taxes increased $6,055,000 to $11,732,000 while income
before provision for income taxes decreased $5,565,000 from income of $4,397,000
to a loss of $1,168,000.  JRM operates in many different tax jurisdictions.
Within these jurisdictions, tax provisions vary because of nominal rates,
allowability of deductions, credits and other benefits, and even tax basis (for
example, revenue versus income). These variances, along 

                                       14
<PAGE>
 
with variances in the mix of income within jurisdictions, are responsible for
shifts in the effective tax rate.

EFFECTS OF INFLATION AND CHANGING PRICES

JRM's financial statements are prepared in accordance with generally accepted
accounting principles, using historical dollar accounting (historical cost).
Statements based on historical cost, however, do not adequately reflect the
cumulative effect of increasing costs and changes in the purchasing power of the
dollar, especially during times of significant and continued inflation.

In order to minimize the negative impact of inflation on its operations, JRM
attempts to cover the increased cost of anticipated changes in labor, material
and service costs, either through an estimation of such changes, which is
reflected in an original price, or through price escalation clauses in its
contracts.

LIQUIDITY AND CAPITAL RESOURCES

During fiscal year 1998, JRM's cash and cash equivalents increased $15,216,000
to $152,011,000 and total debt decreased $122,998,000 to $277,094,000, primarily
due to repayment of $84,352,000 in long-term debt and a net reduction in short-
term borrowings of $26,068,000.  During this period, JRM provided cash of
$371,999,000 from operating activities and received cash of $287,241,000 from
the disposition of assets and $5,599,000 from the issuance of stock upon
exercise of stock options.  JRM used cash of $465,776,000 for net purchases of
investments, $27,145,000 for additions to property, plant and equipment,
$13,537,000 for purchases of treasury stock, and $7,200,000 for cash dividends
on preferred stock.  In addition, JRM used cash of $14,543,000 for acquisitions
of net assets from International.

On December 19, 1997, JRM and Heerema terminated the HeereMac joint venture.
Pursuant to the termination, Heerema acquired and assumed JRM's 50% interest in
the joint venture in exchange for cash of $318,500,000 and title to several
pieces of equipment, including two launch barges and the derrick barge 101, a 3,
500-ton lift capacity, semi-submersible derrick barge.  The consideration
received included a $61,637,000 distribution of earnings of the HeereMac joint
venture and payment of principal and interest under a promissory note previously
due to JRM (approximately $100,000,000).  As a result of the termination, a gain
on asset disposal of $224,472,000 and a distribution of earnings of $61,637,000
were recorded.  JRM invested the cash proceeds it received in debt securities.

Expenditures for property, plant and equipment decreased $37,116,000 to
$27,145,000 in fiscal year 1998.  The majority of fiscal year 1998 expenditures
were to maintain, replace and upgrade existing facilities and equipment.  JRM
has committed to make capital expenditures of approximately $24,541,000 during
fiscal year 1999.

At March 31, 1998 and 1997, JRM had available various uncommitted short-term
lines of credit from banks totaling $25,234,000 and $43,091,000, respectively.
Borrowings against these lines of credit at March 31, 1998 and 1997 were
$2,251,000 and $28,610,000, respectively.  JRM was also a party to an unsecured
and committed revolving credit facility (the "JRM Revolver").  There were no
borrowings outstanding at March 31, 1998 and 1997 under the JRM Revolver.  The
JRM Revolver expired on June 8, 1998.  JRM 

                                       15
<PAGE>
 
is currently negotiating a $200,000,000 three year unsecured committed revolving
credit and letter of credit facility. Borrowings against the facility cannot
exceed $50,000,000. The remaining $150,000,000 will be reserved for the issuance
of letters of credit. Management does not anticipate that JRM will need to
borrow funds under the new facility during fiscal year 1999.

JRM is restricted, as a result of covenants in its indenture relating to its
$250,000,000 9.375% Senior Subordinated Notes due July 2006, from paying cash
dividends on, or repurchasing or redeeming, its capital stock (including the
shares of Common Stock and Series A Preferred Stock held by International), or
in transferring funds through unsecured loans to or investments in
International.  At March 31, 1998, JRM could pay cash dividends on, or
repurchase shares of, its capital stock (including shares held by International)
in the amount of $37,633,000, could pay up to an additional $9,600,000 of cash
dividends on its Series A Preferred Stock held by International, and could make
unsecured loans to or investments in International of approximately $30,000,000.
Additionally under such indenture, JRM is required to offer to purchase its
outstanding 9.375% Senior Subordinated Notes at 100% of their principal amount,
plus accrued and unpaid interest, to the extent that it has proceeds from
certain asset sales and dispositions equal to or exceeding $25,000,000 that it
has not used to permanently reduce certain senior or other indebtedness or
reinvested in its business within a specified time period, generally 18 months,
following each such asset sale or disposition.  Currently, JRM has approximately
$240,000,000 in proceeds from such asset sales and dispositions, which, if not
used for repayment of debt or reinvested as described above, would be subject to
this obligation commencing June 1999.

During fiscal year 1998, JRM's Board of Directors approved a limited stock buy
back program.  Under the program, JRM can purchase up to two million shares of
its Common Stock from time to time on the open market or through negotiated
transactions, depending on the availability of cash and market conditions.
JRM's plan is also dependent on its ability to satisfy its debt covenants.  As
of March 31, 1998, JRM had purchased 362,500 shares of its Common Stock at an
average share price of $37.31 under the program.

JRM maintains an investment portfolio of government obligations and other
investments.  The fair value of long-term investments in debt securities at
March 31, 1998 was $543,658,000.

Working capital decreased $112,265,000 to $7,173,000 at March 31, 1998 from
$119,438,000 at March 31, 1997.  During 1999, JRM expects to obtain funds to
meet working capital, capital expenditure and debt maturity requirements from
operating activities and from cash and cash equivalents.  Leasing agreements for
equipment, which are short-term in nature, are not expected to impact JRM's
liquidity or capital resources.

JRM joint ventures are largely financed through their own resources, including,
in some cases, stand-alone borrowing arrangements.

During fiscal year 1998 and 1997, JRM paid dividends of $7,200,000 on its Series
A Preferred Stock.  JRM has annual preferred stock dividend requirements of
$7,200,000 on its Series A Preferred Stock.

                                       16
<PAGE>
 
At March 31, 1998, the ratio of long-term debt to total stockholders' equity was
0.40 as compared with 0.50 at March 31, 1997.

JRM has provided a valuation allowance ($17,196,000 at March 31, 1998) for
deferred tax assets which cannot be realized through carrybacks and future
reversals of existing taxable temporary differences. Management believes that
remaining deferred tax assets are realizable through carrybacks and future
reversals of existing taxable temporary differences and future taxable income.
An uncertainty that affects the ultimate realization of deferred tax assets is
the risk of incurring losses in the future.  This factor has been considered in
determining the valuation allowance.  Management will continue to assess the
adequacy of the valuation allowance on a quarterly basis.

IMPACT OF THE YEAR 2000

The Year 2000 issue is the result of computer systems being written using two
digits rather than four to define the applicable year.  This could result in a
system failure or miscalculations causing disruptions of operations, including,
among other things, a temporary inability to process transactions, send
invoices, or engage in similar normal business activities.  JRM has established
a Year 2000 risk management program to identify and correct problems associated
with the Year 2000 issue.  The scope of JRM's Year 2000 risk management program
covers computer systems, process control systems and products liability.

Based on assessments, JRM has determined that it will be required to modify or
replace significant portions of its computer systems so that those systems will
function properly with respect to dates in the Year 2000 and thereafter.  JRM
presently believes that with modifications to existing software and conversions
to new software, the Year 2000 issue will not pose significant operational
problems for its computer systems.  Operating system upgrades, application
remediation and application replacement projects are in progress.  If
modifications and conversions are not made, or are not completed timely, the
Year 2000 issue could have a material impact on the operations of JRM.

JRM has initiated a program to determine the nature of potential exposure
related to the Year 2000 issue for products it has sold, to develop a
communication program for customers potentially impacted, and to assess process
control systems.  JRM does not expect this exposure to have a material adverse
effect on its results of operations.

JRM will use both internal and external resources to reprogram, replace, and
test the software for Year 2000 modifications.  JRM is anticipating having its
critical systems Year 2000 compliant no later than June 30, 1999, which is prior
to any anticipated impact on its business.  The cost of the Year 2000
remediation project is estimated at $6,000,000 and is being funded through
operating cash flows.  The cost incurred to date is approximately $1,200,000.

The costs of the project and the dates on which JRM believes it will complete
its Year 2000 project are based on management's best estimates.  These estimates
were derived using numerous assumptions of future events, included continued
availability of resources, third party modification plans, and other factors.
However, there can be no assurance that these estimates will be achieved and
actual results could differ materially from those anticipated.  Specific factors
that might cause such material differences include, but are not limited to, 

                                       17
<PAGE>
 
the availability and cost of personnel, the ability to identify and correct all
Year 2000 impacted areas, and other similar uncertainties.

NEW ACCOUNTING STANDARD

In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income," which is effective for fiscal years beginning
after December 15, 1997. SFAS No. 130 establishes standards for reporting and
display of comprehensive income and its components in a full set of general-
purpose financial statements.  JRM has not yet finalized its review of the
impact of this statement, but it is not expected to have a material impact on
the consolidated financial statements.

                                       18
<PAGE>
 
Item 8.   CONSOLIDATED FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA
          COMPANY REPORT ON CONSOLIDATED FINANCIAL STATEMENTS

JRM has prepared the consolidated financial statements and related financial
information included in this report.  JRM has the primary responsibility for the
financial statements and other financial information and for ascertaining that
the data fairly reflects its financial position and results of operations. The
financial statements were prepared in accordance with generally accepted
accounting principles, and necessarily reflect informed estimates and judgments
by appropriate officers of JRM with appropriate consideration given to
materiality.

JRM believes that it maintains an internal control structure designed to provide
reasonable assurance that assets are safeguarded against loss or unauthorized
use and that the financial records are adequate and can be relied upon to
produce financial statements in accordance with generally accepted accounting
principles.  The concept of reasonable assurance is based on the recognition
that the cost of an internal control structure must not exceed the related
benefits.  Although internal control procedures are designed to achieve these
objectives, it must be recognized that fraud, errors or illegal acts may
nevertheless occur.  JRM seeks to assure the objectivity and integrity of its
accounts by its selection of qualified personnel, by organizational arrangements
that provide an appropriate division of responsibility and by the establishment
and communication of sound business policies and procedures throughout the
organization.  JRM believes that its internal control structure provides
reasonable assurance that fraud, errors or illegal acts that could be material
to the financial statements are prevented or would be detected.

JRM's accompanying consolidated financial statements have been audited by its
independent auditors, who provide JRM with expert advice on the application of
U.S. generally accepted accounting principles to JRM's business and also provide
an objective assessment of the degree to which JRM meets its responsibility for
the fairness of financial reporting.  They regularly evaluate the internal
control structure and perform such tests and other procedures as they deem
necessary to reach and express an opinion on the fairness of the financial
statements.  The report of the independent auditors appears elsewhere herein.

The Board of Directors pursues its responsibility for JRM's consolidated
financial statements through its Audit Committee, which is composed solely of
directors who are not officers or employees of JRM or its parent, International.
The functions of the Audit Committee include the review of matters relating to
the quality of financial reporting and internal control structure and the
nature, extent and results of the audit effort.  In addition, the Audit
Committee is responsible for recommending the engagement of independent auditors
for JRM to the Board of Directors, who in turn submit the engagement to the
stockholders for their approval.  The independent auditors have free access to
the Audit Committee.

                        REPORT OF INDEPENDENT AUDITORS


The Board of Directors and Stockholders
J. Ray McDermott, S.A.


We have audited the accompanying consolidated balance sheet of J. Ray McDermott,
S.A. as of March 31, 1998 and 1997, and the related consolidated statements of
income (loss), stockholders' equity and cash flows for each of the three years
in the period ended March 31, 1998.  These financial statements are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of J. Ray McDermott,
S.A. at March 31, 1998 and 1997, and the consolidated results of its operations
and its cash flows for each of the three years in the period ended March 31,
1998, in conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                FOR THE THREE FISCAL YEARS ENDED MARCH 31, 1998
- --------------------------------------------------------------------------------

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements are presented in U.S. Dollars in
accordance with accounting principles generally accepted in the United States.
The consolidated financial statements include the accounts of JRM, and its
subsidiaries and controlled joint ventures.  Investments in joint ventures and
other entities which JRM does not control, but has significant influence over,
are accounted for on the equity method. Differences between the cost of equity
method investments and the amount of underlying equity in net assets of the
investees are amortized systematically to income. All significant intercompany
transactions and accounts have been eliminated. Certain amounts previously
reported have been reclassified to conform with the presentation at March 31,
1998.

Unless the context otherwise requires, hereinafter "JRM" means J. Ray McDermott,
S.A. and its consolidated subsidiaries; "International" means McDermott
International, Inc., a Panamanian corporation that is the parent company of the
McDermott group of companies and the majority owner of JRM; and "McDermott
International" means the consolidated enterprise.


Use of Estimates

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


Accounting Changes

Earnings Per Share - In December 1997, JRM adopted Statement of Financial
Accounting Standards ("SFAS") No. 128, "Earnings per Share."  SFAS No. 128
replaced the previously reported primary and fully diluted earnings per share
with basic and diluted earnings per share.  Unlike primary earnings per share,
basic earnings per share excludes the dilutive effects of options, warrants, and
convertible securities.  Diluted earnings per share is very similar to the
previously reported fully diluted earnings per share.  All previously reported
earnings per share amounts have been restated to conform to the new
requirements.

Segments - During the fiscal year ended March 31, 1998, JRM adopted SFAS No.
131, "Disclosures about Segments of an Enterprise and Related Information."
SFAS No. 131 establishes standards for the way that public business enterprises
report information about operating segments in annual financial statements  and
requires that those enterprises report selected information about operating
segments in interim financial reports.  SFAS No. 131 also establishes standards
for related disclosures about products and services, geographic areas, and major
customers.  The adoption of SFAS No. 131 did not affect results of operations or
financial position, but did affect the disclosure of segment information.

                                       28

Investments

JRM's investments, primarily government obligations and other debt securities,
are classified as available-for-sale and are carried at fair value, with the
unrealized gains and losses, net of tax, reported in stockholders' equity.
Investment securities available for current operations are classified in the
balance sheet as current assets while securities held for long-term investment
purposes are classified as non-current assets.  The amortized cost of debt
securities is adjusted for amortization of premiums and accretion of discounts
to maturity.  Such amortization is included in interest income.  Realized gains
and losses are included in other income.  The cost of securities sold is based
on the specific identification method.  Interest on securities is included in
interest income.

Foreign Currency Translation

Assets and liabilities of foreign operations, other than operations in highly
inflationary economies, are translated into U.S. Dollars at current exchange
rates and income statement  items are translated at average exchange rates for
the year.  Adjustments resulting from the translation of foreign currency
financial statements are recorded in a separate component of equity.  Foreign
currency transaction adjustments are reported in income.  Included in Other
Income (Expense) are transaction gains (losses) of $4,520,000, $1,108,000, and
($1,916,000) for fiscal years 1998, 1997 and 1996, respectively.  In fiscal year
1998, a gain of $1,005,000 was transferred from currency translation adjustment
and included in gain (loss) on asset disposals and impairments - net due to the
sale of a foreign investment.

Contracts and Revenue Recognition

Contract revenues and related costs are principally recognized on a percentage
of completion method for individual contracts or components thereof based upon
work performed or a cost to cost method, as applicable to the product or
activity involved.  Revenues and related costs so recorded, plus accumulated
contract costs that exceed amounts invoiced to customers under the terms of the
contracts, are included in Contracts in Progress.  Billings that exceed
accumulated contract costs and revenues and costs recognized under percentage of
completion are included in Advance Billings on Contracts.  Most long-term
contracts have provisions for progress payments.  There are no unbilled revenues
which will not be billed.  Contract price and cost estimates are reviewed
periodically as the work progresses and adjustments proportionate to the
percentage of completion are reflected in income in the period when such
estimates are revised.  Provisions are made currently for all known or
anticipated losses.  Variations from estimated contract performance could result
in a material adjustment to operating results for any fiscal quarter or year.
Claims for extra work or changes in scope of work are included in contract
revenues when collection is probable.  Certain partnering contracts contain a
risk and reward element, whereby a portion of total compensation is tied to
overall performance of the alliance partners.

All of the 1998 retainages are expected to be collected within the next year.

Depreciation, Maintenance and Repairs and Drydocking Expenses

Except for major marine vessels, property, plant and equipment is depreciated on
the straight-line method, using estimated economic useful lives of 8 to 30 years
for buildings and 2 to 20 years for machinery and equipment.  Major marine
vessels are depreciated on the units-of-production method based on the
utilization of each vessel.  Depreciation expense calculated under the units-of-
production method may be less than, equal to, or greater than depreciation
expense calculated under the straight-line method in any period. The annual
depreciation based on utilization of each vessel will not be less than the
greater of 25% of annual straight-line depreciation, or 50% of cumulative
straight-line depreciation.

Maintenance, repairs and renewals which do not materially prolong the useful
life of an asset are expensed as incurred except for drydocking costs for the
marine fleet, which are estimated and accrued over the period of time between
drydockings, and such accruals are charged to operations currently.

Amortization of Excess Cost Over Fair Value of Net Assets of Purchased
Businesses

Excess of cost over fair value of net assets of purchased businesses at March
31, 1998 primarily pertains to the acquisitions of Talleres Navales del Golfo,
S.A. de C.V. and Northern Ocean Services Limited and is being amortized on a
straight-line basis over 10 years.

Management periodically reviews goodwill to assess recoverability, and
impairments would be recognized in operating results if a permanent diminution
in value were to occur. During fiscal year 1998, management concluded goodwill
associated with the acquisition of Offshore Pipelines, Inc. ("OPI") in 1995 no
longer had value and recorded a charge for the remaining goodwill of
$262,901,000 (see Note 8).

Capitalization of Interest Cost

In fiscal years 1998, 1997 and 1996, total interest cost incurred was
$31,687,000, $42,295,000 and $44,632,000, respectively, of which $894,000,
$717,000 and $1,325,000, respectively, was capitalized.

Cash Equivalents

Cash equivalents are highly liquid investments, with maturities of three months
or less when purchased, which are not held as part of the investment portfolio.

Derivative Financial Instruments

Derivatives, primarily forward exchange contracts, are utilized to minimize
exposure and reduce risk from foreign exchange fluctuations in the regular
course of business.  Gains and losses relating to qualifying hedges of firm
commitments are deferred and recognized in income or as adjustments of carrying
amounts when the hedged transactions occur.  Gains and losses on forward
exchange contracts which hedge foreign currency assets or liabilities are
recognized in income as incurred.  Such amounts effectively offset gains and
losses on the foreign currency assets or liabilities that are hedged.

Stock-Based Compensation

JRM follows Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees" ("APB 25")  and related Interpretations in accounting for
its employee stock plans.  Under APB 25, if the exercise price of the Company's
employee stock options equals or exceeds the fair value of the underlying stock
on the measurement date, no compensation expense is recognized.  If the
measurement date is later than the date of grant, compensation expense is
recorded to the measurement date based on the quoted market price of the
underlying stock at the end of each period.

NOTE 2 - ACQUISITIONS

During fiscal year 1998, JRM acquired a controlling interest in Talleres Navales
del Golfo, S.A. de C.V., a Mexican shipyard, a 100% interest in Menck GmbH, a
manufacturer of marine hammers, and the remaining interest in McDermott
Engineering Houston, LLC, an engineering joint venture, from International for
an aggregate purchase price of $14,543,000.  These acquisitions have been
accounted for in a manner similar to a pooling of interests and accordingly, the
consolidated financial statements have been restated.

NOTE 3 - INVESTMENT IN UNCONSOLIDATED AFFILIATES

Transactions with unconsolidated affiliates included sales to ($140,389,000,
$110,150,000 and $134,358,000 in fiscal years 1998, 1997 and 1996, respectively,
including approximately $10,491,000, $9,609,000 and $44,491,000, respectively,
attributable to leasing activities) and purchases from ($17,003,000, $8,765,000,
and $9,054,000 in fiscal years 1998, 1997 and 1996, respectively) these
entities.  Included in accounts payable at March 31, 1998 and 1997 were
$16,959,000 and $11,792,000, respectively, of payables to unconsolidated
affiliates.

During fiscal year 1998, JRM and its joint venture partner, Heerema Offshore
Construction Group, Inc. ("Heerema"), terminated the HeereMac joint venture.
Each party had a 50% interest in the joint venture, and Heerema had
responsibility for its day-to-day operations.  Pursuant to the termination,
Heerema acquired and assumed JRM's 50% interest in the joint venture in exchange
for cash of $318,500,000 and title to several pieces of equipment, including two
launch barges and the derrick barge 101, a 3500-ton lift capacity, semi-
submersible derrick barge.  The consideration received included a distribution
of earnings of the HeereMac joint venture and payment of principal and interest
under a promissory note previously due to JRM (approximately $100,000,000).  As
a result of the termination, a gain on asset disposal of $224,472,000 and a
distribution of earnings of $61,637,000 were recorded.

During fiscal year 1997, JRM changed from the equity to the cost method of
accounting for its investment in the HeereMac joint venture as a result of JRM's
determination that it was unable to exercise significant influence over
HeereMac's operating and financial policies.  Equity income of HeereMac was
$1,083,000 in fiscal year 1996.

In fiscal year 1997, JRM realized a gain of $16,682,000 on the sale of a marine
vessel by HeereMac on behalf of JRM.  During fiscal year 1996, JRM sold to the
HeereMac joint venture the major marine vessels that it had been leasing to the
joint venture.  JRM received cash of $135,969,000, including a $30,000,000
advance deposit on the sale of certain marine equipment which was completed
during fiscal year 1997, and a 7.75% note receivable of $105,000,000 and
recorded a deferred gain of $103,239,000, which was being amortized over
HeereMac's depreciable lives of the vessels prior to the change to the cost
method of accounting for JRM's investment in HeereMac.  Subsequent to the
change, the deferred gain 

                                       32
<PAGE>
 
was recognized by JRM as the note was repaid. The note receivable ($92,500,000
at March 31, 1997), net of the deferred gain ($90,803,000 at March 31, 1997) was
included in investment in unconsolidated affiliates. In addition to the vessel
sale in fiscal year 1996, JRM received $37,097,000 as a return of capital from
the HeereMac joint venture.

At March 31, 1998 and 1997, property, plant and equipment included $137,513,000
and $141,409,000, and accumulated depreciation included $113,528,000 and
$102,242,000, respectively, of marine equipment that is leased to unconsolidated
investees.  Dividends received from unconsolidated investees accounted for by
the equity method were $1,290,000 and $2,291,000 in fiscal years 1998 and 1996,
respectively. Undistributed earnings in unconsolidated affiliates accounted for
by the equity method were $16,238,000 and $12,937,000, respectively, at March
31, 1998 and 1997.

most recent financial information, for investments in entities accounted for by
the equity method are presented below:

West, Inc. The Consolidated Statement of Income (Loss) for fiscal years 1998,
1997, and 1996, respectively, includes revenues of $74,096,000, $44,033,000 and
$23,290,000 and operating income (loss) of $18,751,000, ($22,956,000) and
($1,086,000) attributable to operations transferred to ETPM S.A..

Subsequent to the fiscal year end, JRM's Malaysian joint venture sold two
combination pipelay  and derrick barges.  The joint venture, in which JRM holds
a 49% interest, received approximately $47,000,000 in cash for the barges.

NOTE 4 - INCOME TAXES

Income taxes have been provided based upon the tax laws and rates in the
countries in which operations are conducted. All income has been earned outside
of Panama and JRM is not subject to income tax in Panama on income earned
outside of Panama.  Therefore, there is no expected relationship between the
provision for income taxes and income before income taxes.  The major reason for
the variations in such relationships is that income is earned within and subject
to the taxation laws of various countries, each of which has a regime of
taxation which varies from that of any other country (not only with respect to
nominal rate but also with respect to the allowability of deductions, credits
and other benefits) and because the proportional extent to which income is
earned in, and subject to tax by, any particular country or countries varies
from year to year. JRM and certain of its subsidiaries keep books and file tax
returns on the completed contract method of accounting.

Deferred income taxes reflect the net tax effects of temporary differences
between the financial and tax bases of assets and liabilities.  Significant
components of deferred tax assets and liabilities as of March 31, 1998 and 1997
were as follows:

Provision for Income Taxes        $34,851      $ 11,732    $  5,677
====================================================================

The current provision for other than U.S. income taxes in 1998, 1997 and 1996
includes a reduction of $10,427,000, $2,021,000 and $3,763,000, respectively,
for the benefit of net operating loss carryforwards.  Initial recognition of OPI
pre-acquisition tax benefits in fiscal year 1997 resulted in a reduction of
excess cost over fair value of assets acquired of $3,115,000.

JRM has provided a valuation allowance ($17,196,000 at March 31, 1998) for
deferred tax assets which cannot be realized through carrybacks and future
reversals of existing taxable temporary differences. Management believes that
remaining deferred tax assets are realizable through carrybacks and future
reversals of existing taxable temporary differences and future taxable income.
An uncertainty that affects the ultimate realization of deferred tax assets is
the risk of incurring losses in the future.  This factor has been considered in
determining the valuation allowance.  Management will continue to assess the
adequacy of the valuation allowance on a quarterly basis.

JRM would be subject to U.S. withholding taxes on distributions of earnings from
its U.S. subsidiaries.  No U.S. withholding taxes have been provided as these
earnings are considered indefinitely reinvested.

During fiscal year 1997, JRM paid a $231,000,000 note payable to International
and purchased from International certain diving support equipment and systems
for $3,573,000 and nine cranes for use in JRM's fabrication and construction
activities for $8,295,000.  During fiscal year 1998, a tax adjustment of
$1,128,000 on the above purchase was included in Capital in Excess of Par Value.

Under a non-competition agreement entered into in connection with the
acquisition of OPI, a director who resigned in April 1996 received $1,500,000 in
fiscal years 1998, 1997 and 1996 and will receive additional payments of
$1,500,000 per year over the next two years.

In fiscal year 1995, JRM entered into an office sublease with an affiliate of
one of its directors (who resigned in April 1996).  Such sublease expired in
March 1997.  During fiscal years 1997 and 1996, the affiliate paid $216,000 and
$185,000, respectively, under the sublease.  Under another agreement, JRM paid
$576,000 to the affiliate in each of fiscal years 1997 and 1996 and reimbursed
the affiliate for out-of-pocket expenses for the management and operation of
JRM's offshore producing oil and gas property.  Also during fiscal year 1996,
JRM fabricated a caisson for the affiliate for $84,000.  In addition, JRM
received approximately $2,000,000 from the affiliate during fiscal year 1996
pursuant to a contract to refurbish, transport and install an offshore jacket
and deck.

JRM entered into agreements with an affiliate of another director (whose term as
director ended in August 1997) pursuant to which JRM acquired interests in
certain offshore oil and gas property.  During fiscal year 1996, JRM paid
$2,036,000 to the affiliate under the agreements in connection with the
acquisition of its interests and the development of such property.  During
fiscal year 1996, JRM sold its interest in the property to the affiliate in
exchange for an $8,000,000 convertible production payment relating to such
property.  Pursuant to the terms of the agreements entered into in connection
with such sale, JRM received a right to a production payment that allows it to
share in up to $8,000,000 of the net proceeds on any production from the
property based upon a percentage of its original interest in such property.  In
December 1995, this property was placed on production and JRM earned
approximately $1,262,000, $1,093,000 and $179,000 in fiscal years 1998, 1997 and
1996, respectively, 

                                       37

under these agreements. In addition, during fiscal year 1998, JRM sold its
investment in common stock of this affiliate and its interest in a limited
partnership which is also an affiliate of this director. JRM also entered into
agreements with two affiliates of the same former director to design, fabricate
and install several offshore pipelines or structures. The value of these
agreements was approximately $82,000,000. At March 31, 1997, all work under
these agreements had been completed and invoiced.

McDermott International provides administrative services to JRM under a service
agreement.  These services include, but are not limited to: accounting,
treasury, tax administration and other financial services; human relations;
public relations; corporate secretarial; and corporate officer services.  The
cost of these services to JRM was $13,148,000, $11,900,000 and $11,900,000 for
fiscal years 1998, 1997 and 1996, respectively. McDermott International also
provides other administrative services which are billed directly to JRM.  These
services include, but are not limited to, telecommunications and automation.
The cost of these services to JRM was $5,197,000, $6,629,000 (including
$2,087,000 for corporate officer severance) and $6,615,000 for fiscal years
1998, 1997 and 1996, respectively.

Certain officers and employees of JRM participate in certain benefit plans which
involve the issuance of International Common Stock.

During fiscal year 1997, JRM issued $250,000,000 principal amount 9.375% Senior
Subordinated Notes due 2006 ("9.375% Notes").  The 9.375% Notes are redeemable,
for cash, at the option of JRM in whole or in part, at any time on or after July
15, 2001 at a price of 104.688% of the principal amount, and thereafter at
prices declining annually to 100% of the principal amount on or after July 15,
2004.

Maturities of long-term debt during the five fiscal years subsequent to March
31, 1998 are as follows: 1999 - $29,021,000; 2000 - $721,000; 2001 - $38,000;
2002 - $38,000; 2003 - $39,000.

At March 31, 1998 and 1997, JRM had available various uncommitted short-term
lines of credit from banks totaling $25,234,000 and $43,091,000, respectively.
Borrowings by JRM against these lines of credit at March 31, 1998 and 1997 were
$2,251,000 and $28,610,000, respectively.  JRM is also a party to an unsecured
and committed revolving credit facility (the "JRM Revolver").  There were no
borrowings outstanding at March 31, 1998 and 1997 under the JRM Revolver.  As a
condition to borrowing under the JRM Revolver, JRM must comply with certain
covenant requirements.  Presently, JRM cannot satisfy these requirements and
cannot borrow under the JRM Revolver.  The JRM Revolver also limits the amount
of funds which JRM can borrow from other sources and JRM is presently at these
limits.  The JRM Revolver will expire on June 8, 1998.  JRM is currently
negotiating a new three year unsecured committed revolving credit and letter of
credit facility.

JRM is restricted, as a result of covenants in its indenture relating to its
9.375% Notes, from paying cash dividends on, or repurchasing or redeeming, its
capital stock (including the shares of Common Stock and Series A Preferred Stock
held by International), or in transferring funds through unsecured loans to or
investments in International.  At March 31, 1998, JRM could pay cash dividends
on, or repurchase shares of, its capital stock (including shares held by
International) in the amount of $37,633,000, could pay up to an additional
$9,600,000 of cash dividends on its Series A Preferred Stock held by
International, and could make unsecured loans to or investments in International
of approximately $30,000,000.  Additionally under such indenture, JRM is
required to offer to purchase its outstanding 9.375% Notes at 100% of their
principal amount, plus accrued and unpaid interest, to the extent that it has
proceeds from certain asset sales and 

                                       39

dispositions equal to or exceeding $25,000,000 that it has not used to
permanently reduce certain senior or other indebtedness or reinvested in its
business within a specified time period, generally 18 months, following each
such asset sale or disposition. Currently, JRM has approximately $240,000,000 in
proceeds from such asset sales and dispositions, which, if not used for
repayment of debt or reinvested as described above, would be subject to this
obligation commencing June 1999.

NOTE 7 - PENSION PLANS AND POSTRETIREMENT BENEFITS

Pension Plans - JRM provides retirement benefits through employee participation
in two non-contributory pension plans for substantially all of its salaried
employees, except certain non-resident alien employees of foreign subsidiaries
who are not citizens of a European Community country or who do not earn income
in the United States or the United Kingdom. Plan benefits are based on final
average compensation and years of service.  JRM's funding policy is to fund the
applicable pension plan to meet minimum funding requirements of the Employee
Retirement Income Security Act of 1974 and to fund the other pension plan as
recommended by the respective plan actuary in accordance with applicable law.
At January 1, 1998 and 1997, approximately one-half of total plan assets were
invested in listed stocks and bonds.  The remaining assets were held in foreign
equity funds, U.S. Government securities and investments of a short-term nature.

JRM also provides benefits to employees in the United Kingdom through
participation of certain of its subsidiaries and affiliated companies in a
contributory pension plan sponsored by McDermott International.

Postretirement Health Care and Life Insurance Benefits - JRM offers
postretirement health care and life insurance benefits to substantially all of
its regular full-time employees who retire and receive retirement income from a
defined benefit pension plan funded by JRM, except certain 

                                       42
<PAGE>
 
non-resident alien retired employees who are not citizens of a European
Community country, or who, while employed, did not earn income in the United
States, Canada or the United Kingdom. JRM shares the cost of providing these
benefits, except for certain life insurance plans, with all affected retirees.
JRM does not fund any of these plans.

The following table sets forth the amounts recognized in the consolidated
financial statements at March 31:

Net periodic postretirement benefit cost for fiscal years 1998, 1997 and 1996
included the following components:

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

For measurement purposes, a weighted-average annual assumed rate of increase in
the per capita cost of covered health care claims of 6-1/2% was assumed for
1998, 7-1/2% for 1997 and 10-3/4% for 1996.  For 1999, a rate of 5-1/2% was
assumed.  The rate was assumed to decrease gradually to 4% in 2005 and remain at
that level thereafter.  The health care cost trend rate assumption has a
significant effect on the amounts reported.  For example, increasing the assumed
health care cost trend rates by one percentage point in each year would increase
the accumulated postretirement benefit obligation as of March 31, 1998 by
$3,039,000 and the aggregate of the service cost and interest cost components of
net periodic postretirement benefit cost for fiscal year 1998 by $443,000.

Subsequent Event - Effective April 1, 1998, JRM terminated all postretirement
health care and life insurance benefits for employees.  As a result of the
termination, the total accumulated postretirement benefit obligation of JRM will
decrease.  On the same date, the pension plan for the employees affected by the
termination were amended to increase the benefits payable to offset the cost of
postretirement health care and life insurance to the participants.  As a result
of the amendment to the plan, the total projected benefit obligation of JRM will
increase.  The decrease in the accumulated postretirement benefit obligation
will be measured against the increase in the total projected benefit obligation
of the pension plan, and any resulting gain or loss will be recognized in the
first quarter of fiscal year 1999.  The actuarial calculations of the decrease
in the total accumulated postretirement benefit obligation and the increase in
the projected benefit obligation of the pension plan have not yet been
finalized.

NOTE 8 - IMPAIRMENT OF LONG-LIVED ASSETS

During fiscal year 1998, management concluded that the goodwill associated with
the acquisition of OPI no longer had value and recorded a charge for the
remaining goodwill of $262,901,000.  The decision was based on the lack of
volume related to OPI, the departure of key OPI executives from JRM and the
disposal of significant OPI joint ventures and major OPI vessels.  Annual
amortization of the OPI goodwill was approximately $21,800,000.

During fiscal years 1998 and 1997, management identified certain long-lived
assets that are no longer expected to recover their entire carrying value
through future cash flows.  The assets include non-core, surplus and obsolete
property and equipment.  Fair value was generally determined based on sales
prices of comparable assets.  Impairment losses to write down the property,
plant and equipment to estimated fair value totaled $2,891,000 and $19,228,000,
respectively, in fiscal years 1998 and 1997.

During fiscal year 1998, management decided to sell a Floating Production,
Storage and Offloading System ("FPSO").  As a result, an impairment loss of
$7,000,000 was recognized to reduce the FPSO to its estimated fair value less
costs to sell.  Prior to recognition of the impairment loss, the carrying value
of the FPSO was approximately $21,500,000.  Excluding the impairment loss, net
income for fiscal year 1998 for the FPSO was $2,774,000.  Management expects to
sell the FPSO within the next year.

During fiscal year 1997, management decided to sell a certain vessel and related
equipment of a non-core business and to sell or otherwise dispose of certain
other assets.  As a result, impairment losses totaling $12,162,000 were
recognized to reduce the property and equipment to estimated fair values less
the costs to sell.  Prior to recognition of the impairment losses, the carrying
value of these assets totaled approximately $18,950,000.  Excluding the
impairment losses, results of operations for fiscal year 1997 for these assets
were not material. Substantially all of these assets were disposed of in fiscal
year 1998, with no significant gain or loss recognized.

NOTE 9 - CAPITAL STOCK

At March 31, 1998 and 1997, 14,634,966 and 15,172,402 shares, respectively, of
Common Stock were reserved for issuance in connection with the possible
conversion of Series A $2.25 Cumulative Convertible Preferred Stock ("Series A
Preferred Stock"), the exercise of stock 

                                       44
<PAGE>
 
options and awards of restricted stock under JRM's stock incentive plans and
contributions to the Thrift Plan described in Note 10.

At March 31, 1998 and 1997, 3,200,000 shares of Series A Preferred Stock were
owned by International. Shares of Series A Preferred Stock are entitled to one
vote per share, voting as a single class with the Common Stock, and a
liquidation preference of $50.00 per share. Dividends on Series A Preferred
Stock are cumulative at the annual rate of $2.25 per share.  Series A Preferred
Stock is redeemable for cash at the option of JRM, at any time through January
31, 2000 provided that the last reported sales price of JRM's Common Stock in
its principal trading market for any 20 trading days within a period of 30
consecutive trading days is at least $55.74, or any time after January 31, 2000
at a price equal to $52.00 per share, plus accrued and unpaid dividends.  Each
share of Series A Preferred Stock is convertible into 1.794 shares of Common
Stock at any time after a call by JRM for redemption of any or all of the
outstanding Series A Preferred Stock or at any time after January 31, 2000.

During fiscal year 1998, JRM's Board of Directors approved a plan to buy back a
limited number of shares of its Common Stock.  Under the plan, JRM can purchase
up to two million shares of its Common Stock from time to time on the open
market or through negotiated transactions, depending on the availability of cash
and market conditions.  JRM's plan is also dependent on its ability to satisfy
its debt covenants.  As of March 31, 1998, JRM had purchased 362,500 shares of
its Common Stock at an average share price of $37.31 under the plan.

NOTE 10 - STOCK PLANS

A total of 3,217,039 shares of Common Stock are available for stock option
grants and restricted stock awards to officers and key employees under the
Executive Long-Term Incentive Compensation Plan at March 31, 1998.  The Plan
permits the grant of nonqualified stock options, incentive stock options and
restricted stock.  Options to purchase shares are granted at not less than 100%
of the fair market value on the date of the grant, become exercisable at such
time or times as determined when granted and expire not more than ten years
after the date of grant.  Under the Plan, eligible employees may be granted
rights to purchase shares of Common Stock at $1.00 per share, which shares are
subject to restrictions on transfer that lapse at such times and circumstances
as specified when granted.  Through March 31, 1998, a total of 112,940 shares of
restricted stock (including 58,700 and 54,240 shares issued with a weighted
average fair value of $23.78 and $23.25 per share in fiscal years 1997 and 1996,
respectively) have been issued under Plan.  During fiscal year 1998,
performance-based awards represented by initial notional grants totaling 32,510
rights (with a weighted average fair value of $36.53 per right) to purchase
restricted shares of Common Stock were granted to certain officers and key
employees under the Plan.  Under the provisions of the performance-based awards,
no shares are issued at the time of the initial award and the number of shares
which will ultimately be issued shall be determined based on the change in the
market value of JRM's Common Stock over a specified performance period.

A total of 92,500 shares of Common Stock are available for grants of options,
and rights to purchase restricted shares, to non-employee directors under JRM's
Nonemployee Director Stock Plan at March 31, 1998.  Options to purchase 600,
200, and 200 shares will be granted on the first, second, and third years,
respectively, of a Director's term at not less than 100% of the 

                                       45
<PAGE>
 
fair market value on the date of grant, are fully vested and exercisable on the
date of grant and expire ten years after the date of the grant. Rights to
purchase 300, 100 and 100 shares are granted on the first, second and third
years, respectively, of a Director's term, at $1.00 per share, which shares are
subject to restrictions on transfer that lapse at the end of such term. Through
March 31, 1998, a total of 3,100 shares of restricted stock have been issued
under the Nonemployee Director Stock Plan.

Under JRM's 1995 Senior Management Stock Option Plan, senior management
employees may be granted options to purchase shares of Common Stock.  The total
number of shares available for grant is determined by the Board of Directors
from time to time.  Options to purchase shares are granted at not less than 100%
of the fair market value on the date of grant, become exercisable at such time
or times as determined when granted, and expire not more than ten years after
the date of grant.

In the event of a change in control of JRM, all three programs have provisions
that may cause restrictions to lapse and accelerate the exercisability of
options outstanding.

As discussed in Note 1, JRM applies APB 25 and related interpretations in
accounting for its stock-based compensation.  Charges to income related to stock
plan awards totaled approximately $1,541,000, $965,000 and $154,000 for the
fiscal years ended March 31, 1998, 1997 and 1996, respectively.  If JRM had
accounted for its stock plan awards using the alternative fair value method of
accounting under SFAS No. 123, "Accounting for Stock-Based Compensation," its
net income (loss) and earnings (loss) per share would have been the pro forma
amounts indicated below:

                                     1998         1997          1996

The above pro forma information is not indicative of future pro forma amounts.
SFAS No. 123 does not apply to awards prior to fiscal year 1996 and additional
awards in future years are anticipated.  The fair value of each option grant was
estimated at the date of grant using a Black-Scholes option pricing model with
the following weighted-average assumptions:

Thrift Plan

Certain employees of JRM participate in the Thrift Plan for Employees of
McDermott Incorporated and Participating Subsidiary and Affiliated Companies
(the "Thrift Plan"), which is a defined contribution plan maintained by a
subsidiary of McDermott International. On June 5, 1995, a maximum of 5,000,000
of the authorized and unissued shares of JRM's Common Stock was reserved for
possible issuance as the JRM employer match for employee contributions to the
Thrift Plan.  Such employer contributions equal 50% of the first 6% of
compensation, as defined in the Thrift Plan, contributed by participants, and
fully vest and are non-forfeitable after five years of service or upon
retirement, death, lay-off or approved disability.  During fiscal years 1998,
1997 and 1996, 65,727, 77,112 and 80,356 shares, respectively, were issued as
employer contributions pursuant to the Thrift Plan.  At March 31, 1998,
4,776,805 shares remained available for issuance.

NOTE 11 - CONTINGENCIES AND COMMITMENTS

Investigations and Litigation - In March 1997, JRM and International, with the
help of outside counsel, began an investigation into allegations of wrongdoing
by a limited number of former employees of JRM and International and others.
The allegations concerned the heavy-lift business of the  HeereMac joint
venture.  Upon becoming aware of these allegations, JRM and International
notified authorities, including the Antitrust Division of the U. S. Department
of Justice and the European Commission.  As a result of JRM's and
International's prompt disclosure of the allegations, both companies and the
individuals who were officers, directors and employees of JRM or International
at the time of the disclosure were granted immunity from criminal prosecution by
the Department of Justice for any anti-competitive acts involving worldwide
heavy-lift activities.

On December 21, 1997, following JRM's termination of its joint venture with
Heerema Offshore Construction Group, Inc. ("Heerema"), HeereMac and a HeereMac
employee pled guilty to criminal charges by the Department of Justice that they
and others had participated in a conspiracy to rig bids in connection with the
heavy-lift business of HeereMac in the Gulf of Mexico, North Sea and Far East.
HeereMac was fined $49,000,000 and the employee $100,000.  As part of the plea,
both HeereMac and certain employees of HeereMac agreed to cooperate fully with
the Department of Justice investigation.  Neither JRM, International nor any of
their officers, directors or employees was a party to those proceedings.

JRM and International have cooperated and are continuing to cooperate with the
Department of Justice in its investigation.  Near the end of calendar 1997, the
Department of Justice requested additional information from the companies
relating to possible anti-competitive activity in the marine construction
business of McDermott-ETPM East, Inc., one of the operating companies within
JRM's former McDermott-ETPM joint venture with ETPM S.A., a French company.
Pursuant to the termination of the McDermott-ETPM joint venture on April 3,
1998, JRM assumed 100% ownership of McDermott-ETPM East, Inc., which has been
renamed J. Ray McDermott Middle East, Inc.

JRM and International are also cooperating with the Securities and Exchange
Commission ("SEC"), which also requested information and documents from the
companies with respect to certain of the foregoing matters.  JRM and
International are subject to a judicial order entered in 1976, with the consent
of McDermott Incorporated (which at that time was the parent of the McDermott
group of companies), pursuant to an SEC complaint ("Consent Decree").  The
Consent Decree prohibits the companies from making false entries in their books,
maintaining 

                                       48
<PAGE>
 
secret or unrecorded funds or using corporate funds for unlawful purposes.
Violations of the Consent Decree could result in substantial civil and/or
criminal penalties to the companies.

On June 1, 1998, Phillips Petroleum Company (individually, and on behalf of
certain co-venturers) and certain related entities filed a complaint in United
States District Court for the Southern District of Texas against JRM,
International, McDermott Incorporated, McDermott-ETPM, Inc., certain JRM
subsidiaries, HeereMac, Heerema, certain Heerema affiliates,  and others.  The
complaint alleges that the defendants engaged in anti-competitive acts in
violation of Sections 1 and 2 of the Sherman Act and Sections 15.05(a) and (b)
of the Texas Business and Commerce Code, engaged in fraudulent activity and
tortiously interfered with the plaintiffs' businesses in connection with certain
offshore transportation and installation projects in the Gulf of Mexico, North
Sea and Far East.  In addition to seeking actual damages and attorneys' fees,
the plaintiffs have requested punitive as well as treble damages.

It is not possible to predict the ultimate outcome of the Department of Justice
investigation, the SEC inquiry, the companies' internal investigation, the above
referenced lawsuit, or the actions that may be taken by others as a result of
HeereMac's guilty plea or otherwise.  However, these matters could result in
civil and/or criminal liability and have a material adverse effect on JRM's
consolidated financial position and results of operations.

In addition to the foregoing, JRM and certain of its officers, directors and
subsidiaries are defendants in numerous other legal proceedings.  Management
believes that the outcome of these proceedings will not have a material adverse
effect upon JRM's consolidated financial position or results of operations.

Operating Leases - Future minimum payments required under operating leases that
have initial or remaining noncancellable lease terms in excess of one year at
March 31, 1998 are as follows:  1999 - $5,565,000; 2000 - $4,575,000; 2001 -
$3,753,000; 2002 - $1,855,000;  2003 - $1,827,000; and thereafter - $47,685,000.
Total rental expense for fiscal years 1998, 1997 and 1996 was $74,262,000,
$67,990,000 and $66,617,000, respectively.  These expense amounts include
contingent rentals and are net of sublease income, neither of which are
material.

Other - JRM maintains liability and property insurance against such risk and in
such amounts as it considers adequate.  However, certain risks are either not
insurable or insurance is available only at rates which JRM considers
uneconomical.

Commitments for capital expenditures amounted to approximately $24,541,000 at
March 31, 1998, all of which relates to fiscal year 1999.

JRM is contingently liable under standby letters of credit totaling $235,736,000
(including $47,086,000 issued on behalf of unconsolidated joint ventures) at
March 31, 1998, all of which were issued in the normal course of business.

NOTE 12 - FINANCIAL INSTRUMENTS WITH CONCENTRATIONS OF CREDIT RISK

The principal customers of JRM are the offshore oil, natural gas and hydrocarbon
processing industries and other marine construction companies. These
concentrations of customers may impact JRM's overall exposure to credit risk,
either positively or negatively, in that the customers may be similarly affected
by changes in economic or other conditions.  However, 

                                       49
<PAGE>
 
JRM's management believes that the portfolio of receivables is well diversified
and that this diversification minimizes any potential credit risk. Receivables
are generally not collateralized.

JRM believes that its provision for possible losses on uncollectible accounts
receivable is adequate for its credit loss exposure.  At March 31, 1998 and
1997, the allowance for possible losses deducted from Accounts receivable-trade
on the accompanying balance sheet was $2,164,000 and $3,634,000, respectively.

NOTE 14 - DERIVATIVE FINANCIAL INSTRUMENTS

JRM operates internationally giving rise to exposure to market risks from
changes in foreign exchange rates. Derivative financial instruments, primarily
forward exchange contracts, are utilized to reduce those risks. JRM does not
hold or issue financial instruments for trading purposes.

Forward exchange contracts are entered into primarily as hedges of certain firm
purchase and sale commitments denominated in foreign currencies.  At March 31,
1998, JRM had forward exchange contracts to purchase $42,674,000 in foreign
currencies (primarily Pound Sterling and Singapore Dollars), and to sell
$18,910,000 in foreign currencies (primarily Singapore Dollars), at varying
maturities through fiscal year 1999. At March 31, 1997, JRM had forward exchange
contracts to purchase $66,969,000 in foreign currencies (primarily Pound
Sterling), and to sell $257,000 in foreign currencies (primarily Singapore
Dollars), at varying maturities through fiscal year 1998.

Deferred realized and unrealized gains and losses from hedging firm purchase and
sale commitments are included on a net basis in the balance sheet as a component
of either other current assets or accrued liabilities. They are recognized as
part of the purchase or sale transaction when it is recognized, or as other
gains or losses when a hedged transaction is no longer expected to occur. At
March 31, 1998 and 1997, JRM had deferred gains of $586,000 and $2,127,000,
respectively, and deferred losses of $24,000 and $46,000, respectively, related
to forward exchange contracts which will primarily be recognized in accordance
with the percentage of completion method of accounting.

JRM is exposed to credit-related losses in the event of nonperformance by
counterparties to derivative financial instruments, but it does not anticipate
nonperformance by any of the counterparties. The amount of such exposure is
generally the unrealized gains in such contracts.

                                       51

NOTE 15 - FAIR VALUES OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used by JRM in estimating its fair
value disclosures for financial instruments:

Cash and cash equivalents: The carrying amounts reported in the balance sheet
for cash and cash equivalents approximate their fair values.

Investment securities: The fair values of investments are estimated based on
quoted market prices.  For investments for which there are no quoted market
prices, fair values are derived from available yield curves for investments of
similar quality and terms.  The carrying amounts for investments are their
estimated fair values (see Note 13).

Note receivable from an unconsolidated affiliate: At March 31, 1997, it was not
practicable to estimate the fair value of JRM's 7.75% Note Receivable from the
HeereMac joint venture because there were no quoted market prices and the time
of its settlement could not be determined.

Long and short-term debt:  The fair values of debt instruments are based on
quoted market prices or, where quoted prices are not available, on the present
value of future cash flows discounted at estimated borrowing rates for similar
debt instruments or on estimated prices based on current yields for debt issues
of similar quality and terms. At March 31, 1998 and 1997, JRM had total debt
(including notes payable to McDermott International and excluding capitalized
leases) with carrying values of $268,194,000 and $386,816,000 and fair values of
$293,072,000 and $404,876,000, respectively.

Foreign currency exchange contracts:  The fair values of foreign currency
forward exchange contracts are estimated by obtaining quotes from brokers.  At
March 31, 1998 and 1997, JRM had net forward exchange contracts to purchase
foreign currencies with notional values of $23,764,000 and $66,712,000 and fair
values of $24,238,000 and $67,107,000, respectively.

NOTE 16 - SEGMENT REPORTING

JRM supplies worldwide services for the offshore oil and gas exploration and
production and hydrocarbon processing industries, and to other marine
construction companies.  Principal activities include the design, engineering,
fabrication and installation of offshore drilling and production platforms,
specialized structures, modular facilities, marine pipelines and subsea
production systems.  JRM also provides subsea trenching services, diving
services,  procurement activities, and removal, salvage and refurbishment
services for offshore fixed platforms.  These activities are managed and results
are evaluated primarily on a geographic area basis.  Engineering Operations
which includes project management services and engineering services is primarily
managed and evaluated on a worldwide basis.  Other is comprised of chartering
activity as well as consolidating adjustments which pertain to operations but
are excluded from management's evaluation of segment performance.

Intersegment sales are accounted for at prices which are generally established
by reference to similar transactions with unaffiliated customers.  Reportable
segments are measured based on operating income exclusive of general corporate
expenses.  Other reconciling items to income 

                                       52
<PAGE>
 
(loss) before provision for income taxes are interest income, interest expense
and other-net. Corporate assets excluded from segment assets are primarily
investments in debt securities.

On May 7, 1998, JRM sold its interest in McDermott Engineering (Europe) Limited.
Management also intends to exit other European engineering operations.  In
fiscal years 1998, 1997 and 1996, these operations had revenues of $288,687,000,
$295,343,000 and $394,580,000, and operating income of $6,177,000, $9,739,000
and $4,524,000, respectively.

JRM does not believe it is dependent on any one customer. Sales to major
customers that exceeded 10% of revenues were: 1998--customer A $208,299,000
(11%); 1997--customer A  $235,590,000 (17%), customer B $153,274,000 (11%); and
1996--customer A $190,000,000 (15%), customer B $198,453,000 (16%).  Customer A
is a customer of both the North American Operations segment and the Europe
Operations segment.  Customer B is a customer of the Europe Operations segment.
