Items 1 and 2. Business and Properties
 
General
 
  Trico Marine Services, Inc. ("Trico" or the "Company") is a leading provider
of marine support vessels to the oil and gas industry in the U.S. Gulf of
Mexico (the "Gulf"), the North Sea and offshore Brazil. The services provided
by Trico's diversified fleet include the transportation of drilling materials,
supplies and crews to offshore facilities, towing mobile drilling rigs and
equipment from one location to another, and support for the construction,
installation, maintenance and removal of those facilities.
 
  The Company has pursued a strategy of growth through acquisitions. As a
result of these acquisitions, Trico is now the second largest owner and
operator of supply boats in the Gulf and a leading operator in the North Sea.
In December 1997, the Company acquired all of the outstanding stock of Saevik
Supply ASA (together with its subsidiaries, "Saevik Supply"), a then publicly-
traded Norwegian company, for approximately $293.7 million, which amount
includes certain costs of the transaction. The acquisition of Saevik Supply
firmly established Trico in the North Sea market and significantly expanded
its international operations. Since its initial public offering in May 1996,
the Company has also acquired 37 supply boats for use in the Gulf at an
aggregate cost of $177.0 million. Trico currently has a total fleet of 101
vessels, including 55 supply vessels, 11 large capacity platform supply
vessels ("PSV"), seven large anchor handling, towing and supply vessels
("AHTS"), 13 crew boats, six lift boats and nine line-handling vessels.
 
  Trico has also expanded its fleet through the construction of six new
vessels consisting of (i) a 275-foot, technologically advanced AHTS for use in
the North Sea, which is expected to be delivered in June 1999, (ii) two 230-
foot deepwater supply boats, one of which was delivered in December 1998 and
the second to be delivered in the second quarter of 1999, (iii) a "small water
area twin hull" crew boat ("SWATH vessel"), which began a five year contract
for Petrobras in Brazil in January 1999, (iv) a 276-foot PSV in Norway, which
began a three-year charter contract in the U.K. sector of the North Sea in
March 1998, and (v) a 200-foot supply boat, which began a four year contract
for Petrobras in Brazil in July 1998. The Company's new vessels are specially
designed vessels to increase the Company's presence in certain international
and deepwater markets.
 
  Trico has been able to increase total revenues and achieve strong operating
results due to its aggressive strategy of growth through acquisitions and
strong vessel day rates and utilization levels. Beginning in the middle of
1998, however, day rates and utilization for the Gulf supply boat fleet began
to decrease in response to declining industry activity in the Gulf primarily
as a result of low oil prices. The entry of newly-built vessels has also
contributed to the increased competitive environment in the Gulf. However, day
rates and fleet utilization for the Company's Gulf supply boat fleet have
continued to decrease in 1999 primarily as a result of decreased industry
activity in the Gulf, and the Company expects day rates and utilization of its
North Sea fleet to also decline in 1999 compared to 1998. The Company cannot
predict when, or if, oil and gas prices will return to levels sufficient to
cause industry activity levels to increase. The Company believes the diversity
and quality of its fleet, the long-term contracts for many of its vessels in
the North Sea and Brazil, and the addition of its new, larger vessels, which
earn higher day rates, will help to mitigate the impact of the current
industry downturn in the Gulf.
 
The Industry
 
  Marine support vessels are primarily used to transport personnel, equipment
and supplies to drilling rigs, to support the construction and ongoing
operation of offshore oil and gas production platforms and as work platforms
for offshore construction and platform maintenance. The principal services
provided are the transportation of equipment, fuel, water and supplies to
offshore facilities; the transfer of personnel between shore bases and
offshore facilities; and towing services for drilling rigs and platforms. The
principal types of vessels operated by the Company and its competitors can be
summarized as follows:
 
    Supply Boats. Supply boats are generally at least 150 feet in length,
  serve drilling and production facilities and support offshore construction
  and maintenance work. Supply boats are differentiated from other types of
  vessels by cargo flexibility and capacity. In addition to transporting deck
  cargo, such as pipe or drummed materials, supply boats transport liquid
  mud, potable and drilling water, diesel fuel,
 
                                       1
<PAGE>
 
  dry bulk cement and dry bulk mud. Accordingly, larger supply boats which
  have greater liquid mud and dry bulk cement capacities, as well as larger
  areas of open deck space than smaller supply boats, are generally in higher
  demand than vessels without those capabilities. However, other
  characteristics such as maneuverability, fuel efficiency, anchor handling
  ability and firefighting capacity may also be in demand in certain
  circumstances.
 
    Platform Supply Vessels. PSVs serve drilling and production facilities
  and support offshore construction and maintenance work. They are
  differentiated from other offshore support vessels by their cargo handling
  capabilities, particularly their large capacity and versatility. Utilizing
  space on and below deck, they are used to transport supplies such as fuel,
  water, drilling fluids, equipment and provisions. PSVs range in size from
  150 feet to 275 feet and are particularly suited for supporting large
  concentrations of offshore production locations because of their large deck
  space and below deck capacities. The Company's PSVs are primarily in this
  classification but also are capable of providing construction support
  services.
 
    Anchor Handling, Towing and Supply Vessels. AHTSs are used to set anchors
  for drilling rigs and tow mobile drilling rigs and equipment from one
  location to another. In addition, these vessels typically can be used in
  limited supply roles when they are not performing anchor handling and
  towing services. They are characterized by large horsepower (generally up
  to 18,000 brake horsepower ("BHP") for the most powerful North Sea Class
  AHTS vessels), shorter after decks and special equipment such as towing
  winches.
 
    Crew Boats. Crew boats are generally at least 100 feet in length and are
  chartered principally for the transportation of personnel and light cargo,
  including food and supplies, to and among production platforms, rigs and
  other offshore installations. These boats can be chartered together with
  supply boats as support vessels for drilling or construction operations,
  and also can be chartered on a stand-alone basis to support the various
  requirements of offshore production platforms. Crew boats are constructed
  from aluminum, and as a result generally have useful lives beyond those of
  steel-hulled supply boats. These vessels also provide a cost-effective
  alternative to airborne transportation services and can operate reliably in
  virtually all types of weather conditions. Generally, utilization and day
  rates for crew boats are more stable than those of other types of vessels
  because crew boats are typically used to provide services for production
  platforms and construction projects, as well as for exploration and
  drilling activities. The majority of the Company's crew boats are the
  larger 120-foot vessels.
 
    Lift Boats. Lift boats are self-propelled, self-elevating and self-
  contained vessels that can efficiently assist offshore platform
  construction and well servicing tasks that traditionally have required the
  use of larger, more expensive, mobile offshore drilling units or derrick
  barges. For example, lift boats can dismantle offshore rigs, set production
  facilities and handle a variety of tasks for existing platform upgrade
  work. These boats have also been used successfully as the main work
  platform for applications such as diving and salvaging, and have been used
  as an adjacent support platform for applications ranging from crew
  accommodations to full workovers on existing platforms. Historically, lift
  boats command higher day rates but experience lower average utilization
  rates than other classes of marine support vessels. Lift boats have
  different water depth capacities, with leg lengths ranging from 65 to 200
  feet. The Company's lift boats have leg lengths ranging from 130 to 170
  feet, enabling them to operate in water depths where the majority of the
  offshore structures currently in the Gulf are located.
 
    Line Handling Boats. Line handling boats are generally outfitted with
  special equipment to assist tankers while they are loading from single buoy
  mooring systems. These vessels support oil off-loading operations from
  production facilities to tankers and transport supplies and materials to
  and between deepwater platforms.
 
  Gulf of Mexico. As a result of newly-constructed vessels entering the
market, combined with the low price of oil that led to a decrease in drilling
activity in the Gulf, the Company's average supply boat day rates in the Gulf
decreased to $4,341 for the fourth quarter of 1998 compared to $8,037 in the
fourth quarter of 1997. While average supply boat day rates received by the
Company decreased substantially in 1998, average day rates had increased
substantially between 1995 and 1997. The Company's average Gulf supply boat
day rate, which management believes reflected industry-wide day rates,
increased to $8,037 for the fourth quarter of 1997 compared to $6,014 in the
fourth quarter of 1996 and $3,322 in the fourth quarter of 1995. The increased
day
 
                                       2
<PAGE>
 
rates in 1995 through 1997 were due in part to overall increased activity
levels in the Gulf and in part to the reduction in the number of vessels
serving the Gulf and overall industry consolidation. In response, however, to
the increase in day rates and high utilization levels experienced in 1996 and
1997, newly-built vessels have entered the market. The number of offshore
supply boats available for service in the Gulf decreased from a peak of
approximately 700 in 1985 to approximately 320 at the end of 1997 and then
increased to approximately 349 at the end of 1998. During the same period, the
number of companies operating supply boats of at least 150 feet in length
decreased from approximately 80 to 17. The Company estimates that
approximately 30 new supply boats are still in the process of being
constructed for the Gulf market. Many of these supply boats are 220 feet or
greater in length and are specially designed for the deepwater market.
 
  Although the ongoing transportation, maintenance and repair requirements of
offshore production platforms create a baseline demand for marine support
vessels, incremental demand is primarily impacted by the level of offshore oil
and gas drilling activity. The level of drilling activity is influenced by a
number of factors, including oil and gas prices and drilling budgets of
exploration and production companies. As a result, utilization and day rates
generally correlate to oil and gas prices and drilling activity, both of which
declined in 1998. Natural gas currently accounts for approximately 70% of all
hydrocarbon production in the Gulf, and as a result, activity in this region
is highly dependent upon natural gas prices.
 
  North Sea. The North Sea market area consists of offshore Norway, Denmark,
the Netherlands, Germany, Great Britain and Ireland, and the area west of the
Shetlands. Historically, it has been the most demanding of all exploration
frontiers due to harsh weather, erratic sea conditions, significant water
depth and long sailing distances. Exploration and production operators in the
North Sea market are typically large and well capitalized entities (such as
major oil companies and state owned oil companies), in large part because of
the significant financial commitment required in this market. In comparison to
the Gulf, projects in the region tend to be fewer in number, but larger in
scope, with longer planning horizons. Consequently, vessel demand in the North
Sea is generally more steady and less susceptible to abrupt swings than vessel
demand in other regions. Activity in the North Sea generally is at its highest
level during the months from April to August and at their lowest levels during
November to February.
 
  The North Sea market area can be broadly divided into three areas:
exploration, production platform support and field development or
construction. Support of the volatile exploration segment of the market
represents the primary demand for AHTS vessels. While PSVs also support the
exploration segment, they additionally support the production and field
construction segments, which generally are not affected by frequent short-term
swings in demand. However, because AHTS vessels are capable of performing in a
supply role during periods of weakness in the exploration segment, AHTS
vessels can put downward pressure on PSV demand.
 
  The number of vessels in the North Sea has decreased significantly from the
mid-1980s, from a peak of approximately 290 in 1986 to approximately 215 in
1998. As a result of this reduction, together with increased activity in the
North Sea over the past two years, day rates for AHTSs and PSVs of comparable
size to those operated by the Company have increased significantly since
September 1996. Recently, however, there has been an increase in new building
activity in the North Sea market, and as a result of this, and the decrease in
the price of oil, the Company expects day rates and utilization of its North
Sea fleet to decline in 1999 compared to 1998.
 
  Brazil. Offshore exploration and production activity in Brazil is
concentrated in the deep water Campos Basin, located 60 to 100 miles from the
Brazilian coast. Over 50 fields have been discovered in this Basin, including
an estimated 600 currently producing offshore oil wells. A number of fields in
the Campos Basin are being produced using floating production facilities. In
addition, exploration activity has expanded south to the Santos Basin and to
the northeastern and northern continental shelves. Activity levels in the
Brazilian market have primarily been driven by the establishment by the
Brazilian government of national goals for self-sufficiency in oil production.
The primary operator in this market is Petrobras, the Brazilian national oil
company, but in the future the Brazilian government will allow foreign
participation in exploration and production activities in Brazilian waters.

    delivery in the second quarter of 1999.
(2) Includes the Northern Admiral, a 275-foot AHTS that is scheduled for
    delivery in the second quarter of 1999.
(3) Includes the Stillwater River, a SWATH crew boat with 10,600 horsepower.
 
  All the Company's PSVs and AHTSs operate in the North Sea, and the average
age of the Company's North Sea fleet is approximately 11 years. All of the
Company's line-handling vessels are located in Brazil and operate under
charters with Petrobras. The average age of the Company's supply boat Gulf
fleet is approximately 18 years. However, the Company believes that its
upgrade and refurbishment program has significantly extended the service lives
of many of its Gulf supply boats.
 
  Vessel Construction. Trico is completing the construction of the Northern
Admiral, a 275-foot multi-purpose AHTS, with 23,800 horsepower that is
scheduled for delivery in Norway in June 1999. The Company is also completing
the construction of the second of two 230-foot deepwater supply vessels in the
Gulf. The first vessel, the Spirit River, was delivered in December 1998,
while the second vessel, the Hondo River, is scheduled to be completed in the
1999 second quarter.
 
  Lift Boat Management. All of the Company's lift boats are managed by Power
Offshore, Inc. ("Power Offshore"), a leading operator of lift boats in the
Gulf, pursuant to a management agreement that expires in March 1999. Power
Offshore receives a management fee of 10% of the lift boats' monthly gross
income and is eligible to receive an incentive fee based on a percentage of
the lift boats' net operating income. Total management and incentive fees paid
to Power Offshore cannot exceed 13% of the lift boats' gross monthly income.
The Company is also required to reimburse Power Offshore for all operating
expenses relating to the lift boats, excluding marketing and general and
administrative expenses. In addition, Power Offshore has a right of first
refusal if the Company intends to sell to a third party any of the lift boats
that are managed by Power Offshore. The Company is currently in the process of
negotiating a new contract with Power Offshore and expects to renew the
existing contract under similar terms and conditions.
 
  Vessel Maintenance. The Company incurs routine drydock inspection,
maintenance and repair costs under U.S. Coast Guard Regulations and to
maintain American Bureau of Shipping ("ABS") certification for its vessels. In
addition to complying with these requirements, the Company also has its own
comprehensive vessel maintenance program which management believes will help
Trico to continue to provide its customers with well maintained, reliable
vessels. The Company incurred approximately $2.3 million, $10.0 million and
$24.2 million in drydocking and marine inspection costs for the years ended
December 31, 1996, 1997 and 1998, respectively.
 
Operations Bases
 
  The Company supports its operations in the Gulf from a 62.5 acre docking,
maintenance and office facility in Houma, Louisiana located on the
intracoastal waterway that provides direct access to the Gulf. The Company
also leases a 3,600 square foot office in Houston, Texas.
 
                                       4
<PAGE>
 
  The Company's North Sea operations are supported from leased offices in
Fosnavag, Norway, Kristiansand, Norway and Aberdeen, Scotland. Brazilian
operations are supported from a maintenance and administrative facility in
Macae, Brazil, and a sales and administrative office in Rio de Janeiro.
 
Customers and Charter Terms
 
  The Company has entered into master service agreements with substantially
all of the major and independent oil companies operating in the Gulf. The
majority of the Company's charters in the Gulf are short-term contracts (60-90
days) or spot contracts (less than 30 days) and are cancelable upon short
notice. Because of frequent renewals, the stated duration of charters
frequently has little relationship to the actual time vessels are chartered to
a particular customer.
 
  The principal customers in the North Sea market are major integrated oil
companies and large independent oil and natural gas exploration and production
companies as well as foreign government owned or controlled organizations and
companies that provide logistic, construction and other services to such oil
companies and foreign government organizations. The charters with these
customers are industry standard time charters. Current charters in the North
Sea market include periods ranging from just a few days or months to several
years. Eight of the Company's North Sea vessels are on long-term contracts (at
least one year in duration). Five of these eight vessels are on long-term
charters to Statoil and Norsk Hydro, which run to 2000 and 2005, respectively,
with options. Either charterer can, however, terminate its contract during the
period upon payment of agreed compensation. The Company's remaining North Sea
vessels are chartered on a short-term basis.
 
  Charters are obtained through competitive bidding or, with certain
customers, through negotiation. The percentage of revenues attributable to an
individual customer varies from time to time, depending upon the level of
exploration and development activities undertaken by a particular customer,
the availability and suitability of the Company's vessels for the customer's
projects, and other factors, many of which are beyond the Company's control.
For the years ended December 31, 1996 and December 31, 1997, no customer
accounted for more than 10% of the Company's revenues. For the year ended
December 31, 1998, approximately 16% of the Company's total revenues were
received from Statoil AS.
 
Competition
 
  The Company's business is highly competitive. Competition in the marine
support services industry primarily involves factors such as price, service
and reputation of vessel operators and crews, and availability and quality of
vessels of the type and size needed by the customer. Although some of the
Company's principal competitors are larger and have greater financial
resources and international experience than the Company, the Company believes
that its operating capabilities and reputation enable it to compete
effectively with other fleets in the markets in which the Company operates. In
addition to the new vessels the Company has built or is building, certain of
the Company's competitors have built, or are building, new vessels for use in
the Gulf, North Sea and other areas in which the Company operates. This new
construction of vessels has increased the levels of competition within these
markets.
 
Regulation
 
  The Company's operations are materially affected by federal, state and local
regulation, as well as certain international conventions, private industry
organizations and laws and regulations in jurisdictions where the Company's
vessels operate and are registered. These regulations govern worker health and
safety and the manning, construction and operation of vessels. For example,
the Company is subject to the jurisdiction of the U.S. Coast Guard, the
National Transportation Safety Board, the U.S. Customs Service and the
Maritime Administration of the U.S. Department of Transportation, as well as
private industry organizations such as the American Bureau of Shipping. These
organizations establish safety criteria and are authorized to investigate
vessel accidents and recommend improved safety standards.
 
  The U.S. Coast Guard regulates and enforces various aspects of marine
offshore vessel operations, such as classification, certification, routes,
drydocking intervals, manning requirements, tonnage requirements
 
                                       5
<PAGE>
 
and restrictions, hull and shafting requirements and vessel documentation.
Coast Guard regulations require that each of the Company's vessels be
drydocked for inspection at least twice within a five-year period. The Company
believes it is in compliance in all material respects with all U.S. Coast
Guard Regulations.
 
  Under the Merchant Marine Act of 1920, as amended, the privilege of
transporting merchandise or passengers in domestic waters extends only to
vessels that are owned by U.S. citizens and are built in and registered under
the laws of the U.S. A corporation is not considered a U.S. citizen unless,
among other things, no more than 25% of any class of its voting securities are
owned by non-U.S. citizens. If the Company should fail to comply with these
requirements, during the period of such noncompliance it would not be
permitted to continue operating its vessels in coastwise trade.
 
  The Company's operations are also subject to a variety of federal and state
statutes and regulations regarding the discharge of materials into the
environment or otherwise relating to environmental protection. Included among
these statutes are the Clean Water Act, the Resource Conservation and Recovery
Act ("RCRA"), the Comprehensive Environmental Response, Compensation and
Liability Act ("CERCLA"), the Outer Continental Shelf Lands Act ("OCSLA") and
the Oil Pollution Act of 1990 ("OPA").
 
  The Clean Water Act imposes strict controls on the discharge of pollutants
into the navigable waters of the U.S., and imposes potential liability for the
costs of remediating releases of petroleum and other substances. The Clean
Water Act provides for civil, criminal and administrative penalties for any
unauthorized discharge of oil and other hazardous substances in reportable
quantities and imposes substantial potential liability for the costs of
removal and remediation. Many states have laws that are analogous to the Clean
Water Act and also require remediation of accidental releases of petroleum in
reportable quantities. The Company's vessels routinely transport diesel fuel
to offshore rigs and platforms, and also carry diesel fuel for their own use.
The Company's supply boats transport bulk chemical materials used in drilling
activities, and also transport liquid mud which contains oil and oil by-
products. All offshore companies operating in the U.S. are required to have
vessel response plans to deal with potential oil spills.
 
  RCRA regulates the generation, transportation, storage, treatment and
disposal of onshore hazardous and non-hazardous wastes, and requires states to
develop programs to ensure the safe disposal of wastes. The Company generates
non-hazardous wastes and small quantities of hazardous wastes in connection
with routine operations, and management believes that all of the wastes that
the Company generates are handled in compliance with RCRA and analogous state
statutes.
 
  CERCLA contains provisions dealing with remediation of releases of hazardous
substances into the environment and imposes strict, joint and several
liability for the costs of remediating environmental contamination upon owners
and operators of contaminated sites where the release occurred and those
companies who transport, dispose of or who arrange for disposal of hazardous
substances released at the sites. Although the Company handles hazardous
substances in the ordinary course of business, the Company's management is not
aware of any hazardous substance contamination for which it may be liable.
 
  OCSLA provides the federal government with broad discretion in regulating
the release of offshore resources of oil and gas production. Because the
Company's operations rely on offshore oil and gas exploration and production,
if the government were to exercise its authority under OCSLA to restrict the
availability of offshore oil and gas leases, such an action would have a
material adverse effect on the Company's financial condition and the results
of operations.
 
  OPA contains provisions specifying responsibility for removal costs and
damages resulting from discharges of oil into navigable waters or onto the
adjoining shorelines. Among other requirements, OPA requires owners and
operators of vessels over 300 gross tons to provide the U.S. Coast Guard with
evidence of financial responsibility to cover the costs of cleaning up oil
spills from such vessels. The Company has provided satisfactory evidence of
financial responsibility to the U.S. Coast Guard for all of its Gulf vessels
over 300 tons.
 
  Among the more significant of the conventions applicable to the Company's
North Sea operations are: (i) the International Convention for the Prevention
of Pollution of the Sea, 1973, 1979 Protocol, (ii) the
 
                                       6
<PAGE>
 
International Convention on the Safety of Life at Sea, 1974, 1978 and
1981/1983 Protocol, and (iii) the International Convention on Standards of
Training, Certification and Watchkeeping for Seafarers.
 
  The Company believes it is in compliance in all material respects with all
applicable environmental laws and regulations to which it is subject.
Moreover, operations of Company vessels in foreign territories are potentially
subject to similar regulatory controls concerning environmental protection
similar to those in force in the Gulf. The Company believes that compliance
with any existing environmental requirements of foreign governmental bodies
will not materially affect the Company's capital expenditures, earnings, cash
flows or competitive position.
 
Insurance
 
  The operation of the Company's vessels is subject to various risks, such as
catastrophic marine disaster, adverse weather conditions, mechanical failure,
collision and navigation errors, all of which represent a threat to personnel
safety and to Company vessels and cargo. The Company maintains insurance
coverage against certain of these risks, which management considers to be
customary in the industry. The Company believes that its insurance coverage is
adequate and the Company has not experienced a loss in excess of its policy
limits; however, there can be no assurance that the Company will be able to
maintain adequate insurance at rates which management considers commercially
reasonable, nor can there be any assurance that such coverage will be adequate
to cover all claims that may arise.
 
Employees
 
  As of March 11, 1999, the Company had 1,203 employees worldwide, including
1,075 operating personnel and 128 corporate, administrative and management
personnel. None of the Company's U.S. employees are unionized or employed
pursuant to any collective bargaining agreement or any similar arrangement.
The Company's Norwegian seamen are covered by three union contracts that are
between the Norwegian Employer Association for Ship and Offshore Vessels and
(i) masters and mates on offshore vessels, (ii) able-bodied seamen,
electricians and cooks and (iii) engineers, respectively. The Company's U.K.
seamen are covered by two union contracts between Guernsey Ship Management
Limited acting on behalf of the Company and two separate unions, respectively.
The Company believes its relationship with its employees is satisfactory and
to date has not been interrupted by strikes or work stoppages.
 
Cautionary Statements
 
  Certain statements made in this Report that are not historical facts are
"forward-looking statements" as defined in Section 27A of the Securities Act
of 1933 and Section 21E of the Securities Exchange Act of 1934. Such forward-
looking statements may include statements that relate to:
 
  . our objectives, business plans or strategies, and projected or
    anticipated benefits or other consequences of such plans or strategies;
 
  . projected or anticipated benefits from future or past acquisitions; and
 
  . projections involving anticipated capital expenditures or revenues,
    earnings or other aspects of capital projects or operating results.
 
  Also, you can generally identify forward-looking statements by such
terminology as "may," "will," "expect," "believe," "anticipate," "project,"
"estimate" or similar expressions. We caution you that such statements are
only predictions and not guarantees of future performance or events. In
evaluating these statements, you should consider various risk factors,
including but not limited to the risks listed below. These risk factors may
affect the accuracy of the forward-looking statements and the projections on
which the statements are based.
 
  All phases of our operations are subject to a number of uncertainties, risks
and other influences, many of which are beyond our control. Any one of such
influences, or a combination, could materially affect the
 
                                       7
<PAGE>
 
results of our operations and the accuracy of forward-looking statements made
by us. Some important factors that could cause actual results to differ
materially from the anticipated results or other expectations expressed in our
forward-looking statements include the following:
 
  . dependence on the oil and gas industry, including the volatility of
    prices of oil and gas and their effect on industry conditions;
 
  . industry volatility, including the level of offshore drilling and
    development activity and changes in the size of the offshore vessel fleet
    in areas where we operate due to new vessel construction and the
    mobilization of vessels between market areas;
 
  . risks of our growth strategy, including the risks of rapid growth;
 
  . operating hazards, including the significant possibility of accidents
    resulting in personal injury, property damage or environmental damage;
 
  . the effect on our performance of regulatory programs and environmental
    matters;
 
  . the highly competitive nature of the offshore vessel industry;
 
  . the age of our fleet;
 
  . seasonality of the offshore industry in the Gulf;
 
  . the risks of international operations, including currency fluctuations,
    risk of vessel seizure and political instability; and
 
  . the continued active participation of our executive officers and key
    operating personnel.
 
  Many of these factors are beyond our ability to control or predict. We
caution investors not to place undue reliance on forward-looking statements.
We disclaim any intent or obligation to update the forward-looking statements
contained in this Report, whether as a result of receiving new information,
the occurrence of future events or otherwise.
 
  A more detailed discussion of certain of the foregoing factors follows.
 
Market volatility may adversely affect operations
 
  Our operations depend on activity in offshore oil and gas exploration,
development and production. The level of exploration and development activity
has traditionally been volatile as a result of fluctuations in oil and natural
gas prices and their uncertainty in the future. As a result of the decline in
energy prices that began in the middle of 1998, day rates and utilization of
our Gulf supply boat fleet have decreased in response to declining industry
activity. We are unable to predict when, or if, this condition will change. A
further significant decline in the worldwide demand for oil and gas or
prolonged low oil or natural gas prices in the future would likely continue to
depress offshore drilling and development activity. A prolonged low level of
activity in the Gulf and other areas where we operate is likely to adversely
affect the demand for our marine support services and our financial condition
and results of operations.
 
  Charter rates for marine support vessels also depend on the supply of
vessels. Excess vessel capacity in the industry can result primarily from the
construction of new vessels and the mobilization of vessels between market
areas. During the last few years there has been a significant increase in
construction of vessels of the type operated by us, for use both in the Gulf
and the North Sea. The addition of new capacity to the worldwide offshore
marine fleet has increased competition in those markets where we operate. This
new capacity coupled with a prolonged period of low oil and gas prices in the
future would likely have a material adverse effect on our financial condition
and results of operations.
 
Management of growth may increase operating expenses
 
  We have rapidly expanded our operations through acquisitions in the past few
years. The acquisition of Saevik Supply significantly increased the geographic
scope of our operations and our overall size. Our growth has placed, and may
continue to place, substantial demands on our managerial, operational,
financial and other
 
                                       8
<PAGE>
 
resources. In order to manage this growth, we will have to continue to invest
in our operations, including our financial and management information systems.
In addition, we will have to continue our efforts to retain, motivate and
effectively manage our employees. This may affect our operating expenses. If
we fail to achieve and manage this growth as planned, this could adversely
affect our business, financial condition and results of operations.
 
We operate in a highly competitive industry
 
  Our business is highly competitive. Certain of our competitors have
significantly greater financial resources than us and more experience
operating in international areas. Competition in the marine support services
industry primarily involves factors such as:
 
  . price, service and reputation of vessel operators and crews; and
 
  . the quality and availability of vessels of the type and size needed by
    the customer.
 
Operating hazards may increase operating costs; limited insurance coverage
 
  Marine support vessels are subject to operating risks such as catastrophic
marine disaster, adverse weather conditions, mechanical failure, collisions,
oil and hazardous substance spills and navigation errors. The occurrence of
any of these events may result in damage to or loss of our vessels and our
vessels' tow or cargo or other property and in injury to passengers and
personnel. Such occurrences may also result in a significant increase in
operating costs or liability to third parties. We maintain insurance coverage
against certain of these risks, which our management considers to be customary
in the industry. We cannot assure you, however, that we can renew our existing
insurance coverage at commercially reasonable rates or that such coverage will
be adequate to cover future claims that may arise.
 
Compliance with governmental regulations may impose additional expenditures
 
  Federal, state and local regulations, as well as certain international
conventions, private industry organizations and agencies and laws and
regulations in jurisdictions where our vessels operate and are registered,
materially affect our operations. These regulations govern worker health and
safety and the manning, construction and operation of vessels. These
organizations establish safety criteria and are authorized to investigate
vessel accidents and recommend approved safety standards. If we fail to comply
with the requirements of any of these laws or the rules or regulations of
these agencies and organizations, this could adversely affect our operations.
 
  Our operations also are subject to federal, state and local laws and
regulations that control the discharge of pollutants into the environment and
that otherwise relate to environmental protection. While our insurance
policies provide coverage for accidental occurrence of seepage and pollution
or clean up and containment of the foregoing, pollution and similar
environmental risks generally are not fully insurable. We may incur
substantial costs in complying with such laws and regulations, and
noncompliance can subject us to substantial liabilities. The laws and
regulations applicable to us and our operations may change. If we violate any
of such laws or regulations, this could result in significant liability to us.
In addition, any amendment to such laws or regulations that mandates more
stringent compliance standards would likely cause an increase in our vessel
maintenance expenses.
 
Seasonality may adversely affect operations
 
  Our marine operations are seasonal and depend, in part, on weather
conditions. Historically, we have enjoyed our highest utilization rates during
the second and third quarters, as mild weather provides favorable conditions
for offshore exploration, development and construction in the Gulf. Adverse
weather conditions during the winter months generally curtail offshore
development operations and can particularly impact lift boat utilization
rates. Activity in the North Sea is also subject to delays during periods of
adverse weather, but is not affected by seasonality to the extent activity in
the Gulf is affected. Accordingly, the results of any one quarter are not
necessarily indicative of annual results or continuing trends.
 
                                       9
<PAGE>
 
Age of fleet
 
  The average age of our Gulf fleet vessels (based on the date of
construction) is approximately 18 years (approximately 11 years for our North
Sea fleet). Management believes that after a vessel has been in service for
approximately 30 years, repair, vessel certification and maintenance costs may
become no longer economically justifiable. We cannot assure you that we will
be able to maintain our fleet by extending the economic life of existing
vessels through major refurbishment or by acquiring new or used vessels.
 
Currency fluctuations could adversely affect results of operations
 
  The acquisition of Saevik Supply substantially increased the percentage of
our operations conducted in currencies other than the United States dollar.
Changes in the value of foreign currencies relative to the United States
dollar could adversely affect our results of operations and financial
position. In addition, transaction gains and losses could contribute to
fluctuations in our results of operations. Fluctuations in foreign currency
rates may have a material adverse effect on our results of operations.
 
  Our international operations are subject to a number of risks inherent to
any business operating in foreign countries. These risks include, among
others:
 
  . political instability;
 
  . potential vessel seizure or nationalization of assets;
 
  . currency restrictions and exchange rate fluctuations; and
 
  . import and export quotas and other forms of public and governmental
    regulation.
 
  All of these risks are beyond our control. We cannot predict the nature and
the likelihood of any such events. However, if such an event should occur, it
could have a material adverse effect on our financial condition and results of
operations.
 
We depend on key personnel
 
  We depend on the continued services of our executive officers and other key
management personnel. If we were to lose any of these officers or other
management personnel, it could adversely affect our operations.
 
Item 3. Legal Proceedings
 
  The Company is involved in various legal and other proceedings that are
incidental to the conduct of its business. The Company believes that none of
these proceedings, if adversely determined, would have a material adverse
effect on its financial condition, results of operations or cash flows.
 
Item 4. Submission of Matters To a Vote Of Security Holders
 
  None.

Item 7. Management's Discussion and Analysis of Financial Condition and
Results of Operations
 
General
 
  The Company's business strategy has focused on growth and diversifying its
operations through acquisitions. Trico is now the second largest owner and
operator of supply boats in the Gulf and a leading operator in the North Sea.
Trico implemented this strategy by acquiring Saevik Supply in December 1997
for a total acquisition cost of approximately $293.7 million in cash and
purchasing, during 1996 and 1997, 37 supply boats for use in the Gulf at an
aggregate cost of $177.0 million. The Company has also constructed, or is
completing the construction of, six new vessels, and has upgraded and
refurbished the majority of its Gulf supply boat fleet. The Company's newly-
constructed vessels are specially designed vessels to increase the Company's
international and deepwater capabilities.
 
  The Company's results of operations are affected primarily by day rates and
fleet utilization. Demand for the Company's vessels is primarily impacted by
the level of offshore oil and gas drilling activity, which can be influenced
by a number of factors, including oil and gas prices and drilling budgets of
exploration and production companies, and, to a lesser extent, the market for
the maintenance, repair and salvage of existing platforms. As a result, trends
in oil and gas prices may significantly affect utilization and day rates. The
weakness in oil and gas prices experienced in 1998, which resulted in the
lowest price for both oil and gas in recent years, has led to
 
                                      13
<PAGE>
 
a general decline in activity in most areas of the Company's business and has
significantly affected the Company's 1998 results of operations. Day rates and
fleet utilization for the Company's Gulf supply boat fleet have continued to
decrease in 1999 primarily as a result of decreased drilling and development
activity in the Gulf. The Company cannot predict when, or if, oil and gas
prices will return to levels sufficient to cause industry activity levels to
increase.
 
  The Company's day rates and utilization rates are also affected by the size,
configuration and capabilities of the Company's fleet. In the case of supply
boats, PSVs and AHTSs, the deck space and liquid mud and dry bulk cement
capacity are important attributes. In certain markets and for certain
customers, horsepower and dynamic positioning systems are also important
requirements. For crew boats, size and speed are important factors, and in the
case of lift boats, longer leg length and greater crane capacity add
versatility and marketability. The Company's day rates and utilization can
also be affected by the supply of other vessels available in a given market
with a similar configuration and capabilities.
 
  The Company's operating costs primarily are a function of fleet size and
utilization levels. The most significant direct operating costs are wages paid
to vessel crews, maintenance and repairs and marine insurance. Generally,
increases or decreases in vessel utilization only affect that portion of the
Company's direct operating costs that is incurred when the vessels are active.
As a result, direct operating costs as a percentage of revenues may vary
substantially due to changes in day rates and utilization.
 
  In addition to these variable costs, the Company incurs fixed charges
related to the depreciation of its fleet and costs for the routine drydock
inspection, maintenance and repair designed to ensure compliance with U.S.
Coast Guard regulations and to maintain ABS certification for its vessels.
Maintenance and repair expense and marine inspection amortization charges are
generally determined by the aggregate number of drydockings and other repairs
undertaken in a given period. Costs incurred for drydock inspection and
regulatory compliance are capitalized and amortized over the period between
such drydockings, typically two to three years.

-------
(1) Includes results of operations of the vessels purchased through the
    acquisition of Saevik Supply in December 1997. Data for 1997 is for
    December only.
 
 Comparison of the Year Ended December 31, 1998 to the Year Ended December 31,
1997
 
  Revenues for 1998 were $186.2 million, an increase of 48.4%, compared to
$125.5 million in revenues for 1997. This increase was primarily due to the
addition, for a full year, of North Sea operations that were acquired in
December 1997. The increase in revenues from the Company's North Sea
operations was partially offset by a decrease in revenues from the Gulf of
Mexico, principally due to the decrease in average day rates and utilization
for the Company's supply boats. This decrease in supply boat day rates and
utilization was the result of reduced industry activity in the Gulf. Day rates
and utilization for the Company's supply boats was also impacted by the market
entry of newly-constructed vessels, which have increased the competitive
environment in the Gulf.
 
  Average supply boat day rates in the Gulf decreased 7.2% to $6,844 for 1998,
compared to $7,377 for 1997; average lift boat day rates increased 4.1% to
$6,199, compared to $5,955 for 1997; and average day rates for the Company's
crew boats and line handling vessels increased 4.7% to $2,056, compared to
$1,964 during 1997.
 
  Utilization rates for the Company's Gulf supply boats was also impacted by
the significant vessel downtime associated with the Company's extensive vessel
upgrade and refurbishment program for the Gulf of Mexico supply boat fleet.
Utilization for the Company's Gulf supply boat fleet decreased to 62% in 1998
from 85% in 1997. Utilization for the Company's lift boats was 63% during
1998, compared to 71% for the year-ago period. Utilization for the crew boats
and line handling vessels decreased to 94% in 1998, compared to 97% in 1997.
 
  During 1998, direct vessel operating expenses increased to $71.8 million
(38.6% of revenues), compared to $42.2 million (33.6% of revenues) for 1997,
due to the addition of the North Sea fleet and the consolidation for
accounting purposes of the Company's Brazilian subsidiary on July 1, 1998.
Direct vessel operating expenses increased as a percentage of revenues as a
result of the decrease in average vessel day rates and utilization levels
during 1998 in the Gulf.
 
  Depreciation and amortization expense increased to $29.5 million for 1998,
up from $12.7 million for 1997, due to the acquisition of the North Sea
vessels in December 1997, and the expanded vessel fleet in the Gulf of Mexico
and Brazil. Amortization of marine inspection costs increased to $8.9 million
for 1998, from $3.0 million in 1997, because of the amortization of increased
drydocking and marine inspection costs associated with the Company's fleet
upgrade and refurbishment program.
 
                                      15
<PAGE>
 
  General and administrative expenses increased to $10.9 million (5.9% of
revenues) in 1998, from $5.7 million (4.6% of revenues) for 1997, as a result
of the addition of the North Sea operations and the consolidation of the
Company's Brazilian subsidiary beginning July 1, 1998. General and
administrative expenses, as a percentage of revenues, increased in 1998 due to
the decrease in average supply boat day rates and utilization levels in the
Gulf of Mexico.
 
  Interest expense increased to $27.7 million during 1998 compared to $8.0
million for 1997. This increase was due to increased debt in 1998 associated
with the acquisition of the North Sea fleet in December 1997 and increased
borrowings that were used to partially fund the Company's vessel construction
and vessel upgrade and refurbishment program.
 
  In 1998, the Company had income tax expense of $11.8 million, compared to
income tax expense of $19.0 million in 1997.
 
 Comparison of the Year Ended December 31, 1997 to the Year Ended December 31,
1996
 
  Revenues for 1997 were $125.5 million, an increase of 134.6%, compared to
$53.5 million in revenues for 1996. This increase was primarily due to the
growth in the Company's Gulf fleet, improved average vessel day rates for the
Company's vessels and the addition of North Sea operations beginning in
December 1997.
 
  Average supply boat day rates in the Gulf rose 50% to $7,377 for 1997,
compared to $4,917 for 1996; average lift boat day rates increased 19.2% to
$5,955, compared to $4,995 for 1996; and average day rates for the Company's
crew boats and line handling vessels increased 24.3% to $1,964, compared to
$1,579 during 1996. The increase in vessel day rates was primarily the result
of strong market conditions in the Gulf for marine support vessels and, with
respect to the lift boats, improved market conditions in the Gulf for offshore
platform repair and maintenance and well-servicing activities.
 
  While the Company's supply boats experienced strong demand and effectively
full utilization during the year, utilization for the Company's Gulf of Mexico
supply boat fleet decreased in 1997 due to the large number of scheduled
vessel drydockings in 1997 compared to 1996. Utilization for the Company's
lift boats was 71% during 1997, compared to 67% for the year-ago period.
Utilization for the crew boats and line handling vessels increased to 97% in
1997, compared to 95% in 1996 due to continued strong demand for crew boats in
the Gulf and the long-term contracts for the line handling vessels in Brazil.
 
  During 1997, direct vessel operating expenses increased to $42.2 million
(33.6% of revenues), compared to $24.5 million (45.7% of revenues) for 1996,
due to the expanded vessel fleet and increased labor, repair and maintenance
costs. Direct vessel operating expenses decreased as a percentage of revenues
due to the increase in average vessel day rates during 1997 and the growth in
the Company's supply boat fleet which enjoys higher profit margins than the
overall fleet.
 
  Depreciation and amortization expense increased to $12.7 million for 1997,
up from $4.5 million for 1996 due to the expanded vessel fleet. Amortization
of marine inspection costs increased to $3.0 million for 1997, from $2.2
million in 1996, due to the amortization of increased drydocking and marine
inspection costs associated with the Company's larger vessel fleet and the
Company's fleet refurbishment program.
 
  General and administrative expenses increased to $5.7 million (4.6% of
revenues) in 1997, from $3.3 million (6.1% of revenues) for 1996, due to
additions of personnel in connection with the growth in the Company's
operations. General and administrative expenses, as a percentage of revenues,
decreased in 1997 as the increase in revenues and additions to the vessel
fleet did not require proportionate increases in administrative expenses.
 
  Interest expense increased to $8.0 million during 1997 compared to $2.3
million for 1996. This increase was due to increased borrowings in 1997 which
were used to fund the Company's acquisition of supply boats in the Gulf, the
Company's various vessel construction and upgrade projects and the acquisition
of Saevik Supply. In July 1997, the Company issued $110.0 million principal
amount of 8 1/2% Senior notes due 2005 (the "Notes"), the proceeds of which
were used to purchase 11 supply boats in the Gulf and to repay outstanding
amounts
 
                                      16
<PAGE>
 
under the Company's revolving credit facility. In November and December 1997,
the Company issued an additional $170 million principal amount of the Notes,
the proceeds of which were used to fund the acquisition of Saevik Supply.
Interest expense decreased in 1996 due to the repayment of all borrowings
under the Company's credit facility and all of its subordinated debt in May
1996 with proceeds from the Company's initial public offering.
 
  In 1997, the Company had income tax expense of $19.0 million, compared to
income tax expense of $5.8 million in 1996.
 
 Comparison of the Year Ended December 31, 1996 to the Year Ended December 31,
1995
 
  Revenues for 1996 were $53.5 million, an increase of 100% compared to $26.7
million in revenues for 1995. This increase was primarily due to the expansion
in the Company's vessel fleet, both in the Gulf and offshore Brazil, the
strong improvement in average day rates and utilization for the Company's
supply boats, and the increase in utilization for the Company's lift boats.
 
  In 1996, the Company added 26 vessels to its total fleet. In March 1996, the
Company acquired eight line handling vessels, including one vessel owned by
the Company's then 40%-owned affiliate, that currently operate under charters
offshore Brazil. In May 1996 with the proceeds from the Company's initial
public offering, the Company acquired four supply boats and in the remainder
of 1996, acquired a total of 13 additional supply boats in three separate
transactions.
 
  All classes of vessels in the Company's fleet reported higher utilization
during 1996 compared to 1995. The greatest increase in utilization was
experienced by the Company's supply boats and lift boats. Supply boat
utilization averaged 94% for 1996, up from 78% for 1995. Average supply boat
day rates for 1996 increased 60.7% to $4,917 compared to $3,060 for 1995.
These increases reflected strong market conditions in the Gulf during 1996 and
the substantial downtime incurred in 1995 for the vessel upgrade program,
during which three of the Company's supply boats were lengthened from 165 feet
to 180, one was lengthened from 165 feet to 190 feet, and the boats'
capacities for liquid mud and bulk cargo were increased. Additionally, the
Company rebuilt and lengthened a crew boat which was placed in service late in
1995.
 
  Utilization of the Company's lift boats increased to 67% for 1996, from 45%
during 1995. The lift boats experienced unusually low utilization in 1995 due
to drydocking related downtime and weak market conditions which existed in the
first half of 1995. The Company's lift boats are operated by Power Offshore, a
leading operator of lift boats in the Gulf. Management and incentive fees
payable to Power Offshore in 1996 totaled $979,000 as compared to $468,000 for
1995 due to the increased revenue and operating income generated by the lift
boats.
 
  Utilization of the crew boats and line handling vessels increased to 95% for
1996, compared to 85% during the same period in 1995, due to the improved
market conditions in the Gulf for crew boats and the additional eight line
handling vessels acquired in March 1996, which operate under long-term
charters offshore Brazil.
 
  During 1996, direct vessel operating expenses increased to $24.2 million
from $17.0 million during 1995, due to the expanded vessel fleet and increased
labor, repair and maintenance costs. Due to the increase in average vessel day
rates, direct vessel operating expenses decreased as a percentage of revenues
from 63.6% during 1995 to 45.2% during 1996.
 
  Depreciation expense increased to $4.5 million during 1996 from $2.7 million
for 1995 due to the expanded vessel fleet. Amortization of marine inspection
costs increased to $2.2 million during 1996 from $1.9 million for 1995 due to
the amortization of increased drydocking and marine inspection costs.
 
  General and administrative expense increased to $3.3 million during 1996
from $2.5 million during 1995 due to the additional personnel needed in
connection with the growth in the Company's vessel fleet and the addition of
operations in Brazil. General and administrative expenses, as a percentage of
revenues,
 
                                      17
<PAGE>
 
decreased from 9.4% during 1995 to 6.1% in 1996 because the increase in
revenues and additions to the vessel fleet did not require proportionate
increases in administrative expenses.
 
  Interest expense decreased to $2.3 million for 1996, from $3.9 million for
1995. The decrease in interest expense was due to a reduction in the Company's
average bank debt outstanding and lower borrowing costs for the Company in
1996 as compared to 1995. As a result of the Company's two public offerings of
Common Stock completed in May and November 1996, respectively, average bank
debt outstanding decreased to $18.5 million for 1996, compared to $26.6
million for 1995. In 1995 the Company recorded gains on the sales of certain
crew boats of $247,000 versus gains of $50,000 in 1996.
 
  In 1996, the Company had income tax expense of $5.8 million compared to an
income tax benefit of $670,000 in 1995.
 
  As a result of the prepayment of all debt outstanding under the Company's
bank credit facility and its subordinated debt in the second quarter of 1996,
the Company recorded an extraordinary charge of $917,000, net of taxes of
$494,000, for the write-off of unamortized debt issuance costs.
 
Liquidity and Capital Resources
 
  The Company's business strategy for the past several years has been to
enhance its position as a leading supplier of marine support services by
pursuing opportunities to acquire vessel fleets and by diversifying into
international markets. Primarily as a result of acquisitions, the Company's
total assets have grown from $52.1 million at December 31, 1995, to $768.9
million at December 31, 1998. During 1996 and 1997, the Company completed the
acquisition of Saevik Supply, a publicly traded Norwegian company, for a total
acquisition cost of approximately $293.7 million, including transaction costs,
and acquired 37 supply boats in the Gulf for $177.0 million.
 
  The Company has also constructed, or is in the process of constructing, six
new vessels, to increase its international market presence and increase its
deepwater capabilities. Additionally, in 1998, the Company completed its
vessel upgrade and refurbishment program involving a significant portion of
its Gulf supply boat fleet. While this program resulted in significant vessel
downtime in 1998, the Company believes it has extended the service lives of
many of its vessels and has significantly reduced required maintenance
spending in the future.
 
  Capital expenditures for 1998 consisted principally of $101.4 million for
the construction of new vessels and other vessel improvements, and $24.2
million of U.S. Coast Guard drydocking and vessel refurbishment costs. During
1998, $158.2 million in funds were provided by borrowings under the Company's
bank credit facilities, $84.9 million in funds from operating activities and
$6.9 million from the sale of assets. During the period, the Company repaid
$123.3 million of debt.
 
  The Company has outstanding $280.0 million in aggregate principal amount of
the Notes. The Notes are unsecured and are required to be guaranteed by all of
the Company's Significant Subsidiaries (as such term is defined in the
indenture governing the Notes, the "Subsidiary Guarantors"). Except in certain
circumstances, the Notes may not be prepaid until August 1, 2001, at which
time they may be redeemed, at the option of the Company, in whole or in part,
at a redemption price equal to 104.25% plus accrued and unpaid interest, with
the redemption price declining ratably on August 1 of each of the succeeding
three years. The indenture governing the Notes contains certain covenants
that, among other things, limit the ability of the Company to incur additional
indebtedness, pay dividends or make other distributions, create certain liens,
sell assets, or enter into certain mergers or acquisitions.
 
  The Company maintains a bank credit facility that provides up to a $100.0
million revolving line of credit that can be used for acquisitions and general
corporate purposes (the "Bank Credit Facility"). The Bank Credit Facility is
collateralized by a mortgage on certain of the Company's vessels. Amounts
borrowed under the Bank Credit Facility mature on December 1, 2002 and bear
interest at a Eurocurrency rate plus a margin that depends on the Company's
leverage ratio. The weighted average interest rate for the Bank Credit
Facility was 6.8% as of March 1, 1999. The Bank Credit Facility was amended in
December 1998 to reduce permitted borrowings to $85
 
                                      18

million and increasing to $100 million after June 30, 1999 depending on the
Company's leverage ratio. The Bank Credit Facility requires the Company to
maintain certain financial ratios and limits the ability of the Company to
incur additional indebtedness, make capital expenditures, pay dividends or
make certain other distributions, create certain liens, sell assets or enter
into certain mergers or acquisitions. Although the Bank Credit Facility does
impose some limitations on the ability of the Company's subsidiaries to make
distributions to the Company, it expressly permits distributions to the
Company by the Subsidiary Guarantors for scheduled principal and interest
payments on the Notes.
 
  In June 1998, the Company refinanced Saevik Supply's existing bank credit
facilities with a revolving credit facility in the amount of NOK 650 million,
or $81.8 million (the "Saevik Bank Facility"). As of March 1, 1999, the
Company had approximately NOK 395 million ($49.7 million) of debt outstanding
under the Saevik Bank Facility. The Saevik Bank Facility is collateralized by
a security interest in certain of the Company's North Sea vessels, requires
Saevik Supply to maintain certain financial ratios and limits the ability of
Saevik Supply to create liens, or merge or consolidate with other entities.
Amounts borrowed under the Saevik Bank Facility bear interest at NIBOR
(Norwegian Interbank Offered Rate) plus a margin. The weighted average
interest rate for the Saevik Bank Facility was 7.66% as of March 1, 1999. The
commitment amount for the Saevik Bank Facility reduces by NOK 50 million ($6.3
million) every six months beginning December 1998, with the balance of the
commitment to expire in June 2003.
 
  In connection with the construction of the Company's SWATH vessel, in April
1998 the Company issued $10.0 million aggregate principal amount of 8 year,
6.08% Ship Financing Bonds (the "Ship Bonds") guaranteed by the United States
Government. The Ship Bonds are due in 16 semi-annual installments of principal
and interest, with the first principal payment due March 1, 1999, and are
secured by a first preferred ship mortgage on the SWATH vessel and by an
assignment of the vessel's charter. The proceeds of the Ship Bonds were used
to repay a portion of the amounts outstanding under the Company's Bank Credit
Facility.
 
  Due to industry conditions, the Company intends to limit 1999 capital
expenditures to those required to complete existing vessel construction
projects and regulatory-mandated drydocking costs. In order to further reduce
its maintenance capital expenditures, the Company expects to deactivate, or
"stack," an average of between 10 and 12 of its Gulf supply boats during 1999
that were not refurbished as part of its vessel upgrade and refurbishment
program.
 
  Capital expenditures planned for 1999 consist primarily of the remaining
costs to complete two new vessels currently under construction. Expenditures
for the two new vessels in 1999 are expected to total approximately $24.4
million. The Company is completing construction in Norway of the Northern
Admiral, a 275-foot, technologically advanced AHTS with 23,800 horsepower that
is scheduled to be delivered in June 1999. The Company is also completing
construction in the Gulf of the Hondo River, the second of two deepwater 230-
foot supply vessels. The first vessel, the Spirit River, was delivered in
December 1998, while the Hondo River will be completed in the second quarter
of 1999. The Company has a pending application and expects to receive a
commitment from the U.S. Maritime Administration's Title XI ship financing
program to provide long-term financing for approximately $18.8 million of the
cost of the Spirit River and the Hondo River.
 
  The Company believes that cash generated from operations together with
available borrowings under its bank credit facilities will be sufficient to
fund the Company's currently planned capital projects and working capital
requirements. The Company's business strategy has historically been to grow
through acquisitions to expand its operating capabilities and international
operations. As a result of depressed worldwide oil prices and reduced drilling
and development activity in most international areas, the Company believes
that in 1999 it may identify additional acquisition opportunities. Depending
upon the size of any acquisition, it is likely that the Company would require
additional equity financing and may incur additional debt financing in order
to complete the acquisition. The Company believes that any such financing
would involve the issuance of either common stock, convertible preferred stock
or other securities entitling the holders to acquire common stock.
 
Year 2000 Compliance
 
  In accordance with the U.S. Securities and Exchange Commission's ("SEC")
Staff Legal Bulletin No. 5 and the SEC's subsequent interpretive release, the
Company has assessed both the cost of addressing and the cost
 
                                      19
<PAGE>
 
or the consequence of incomplete or untimely resolution of the Year 2000
("Y2K") issue. This process includes (i) the development of Y2K awareness,
(ii) a comprehensive review to identify systems that could be affected by the
Y2K issue, (iii) an assessment of potential risk factors (including non-
compliance by the Company's suppliers, subcontractors and customers), (iv) the
allocation of required resources, (v) a determination of the extent of
remediation work required, (vi) the development of an implementation plan and
time table, and (vii) the development of contingency plans.
 
  The Company, in the normal course of business, is in the process of
replacing its accounting and certain other information systems, and has
established a target date of mid-1999 for their installation at all locations.
While the Company's growth is driving the Company's efforts to replace these
systems, the Company does expect the implementation of the new systems to
mitigate any potential Y2K issues related to any of its existing systems.
 
  In addition, the Company's information systems personnel are currently
working with its third party vendors to resolve the potential problems
associated with the year 2000 and the processing of date sensitive information
by the Company's computer and other systems. The Company is still evaluating
the Y2K effect on other computer systems and non-information technology
systems, including telephone systems, office and vessel-based electronic
equipment and devices with embedded microprocessors. Additionally, the Company
has contacted key vendors and suppliers to ensure that they have a Y2K
compliance plan in an effort to minimize the Company's exposure to their
potential Y2K problems. The Company anticipates completion of its evaluation
of non-information technology equipment, key vendors and suppliers and any
remedial action and/or a contingency plan, if necessary, by mid-1999.
 
  Because of the Company's purchase of new software and conversions to new
software, the Y2K issue is not expected to pose significant operational
problems for the Company's computer systems. However, if such modifications or
conversions are not made or are not completed on time, the Y2K issue could
have an adverse impact on the Company's operations. Among other things the
Company could be impacted by: the inability of the Company to retain qualified
personnel and outside consultants to successfully remediate Y2K issues and
implement a new business system as demand for their services rises; the
inability of the Company's customers to accurately and timely pay invoices;
the inability of the Company to access necessary capital from lenders or other
sources when required; and the inability of the Company's significant
suppliers, subcontractors and others to provide the necessary materials,
services or systems required to operate the Company's business.
 
  The Company believes that it will be able to implement successfully the
changes necessary to address the Y2K issues with reliance on its third party
vendors and does not expect the cost of such changes to have a material impact
on the Company's financial position, results of operations or cash flows in
future periods.
 
New Accounting Standards
 
  In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards, No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS No. 133"), effective for all fiscal
quarters of fiscal years beginning after June 15, 1999. The Company is
currently evaluating the impact SFAS No. 133 will have on its financial
statements, if any.
 
Item 7A. Quantitative and Qualitative Disclosures About Market Risk
 
  The Company's market risk exposures primarily include interest rate and
exchange rate fluctuation on derivative and financial instruments as detailed
below. The Company's market risk sensitive instruments are classified as
"other than trading". The following sections address the significant market
risks associated with the financial activities of the Company during 1998. The
Company's exposure to market risk as discussed below includes "forward-looking
statements" and represents estimates of possible changes in fair values,
future earnings or cash flows that would occur assuming hypothetical future
movements in foreign currency exchange rates or interest rates. The Company's
views on market risk are not necessarily indicative of actual results that may
occur and do not represent the maximum possible gains and losses that may
occur, since actual gains and losses will differ from those estimated, based
upon actual fluctuations in foreign currency exchange rates, interest rates
and the timing of transactions.
 
                                      20

Interest Rate Sensitivity
 
  The Company has entered into a number of variable and fixed rate debt
obligations, denominated in both the U.S. Dollar and the Norwegian Kroner
(Norwegian debt payable in Norwegian Kroner), as detailed in Note 7 to the
Company's December 31, 1998 financial statements. These instruments are
subject to interest rate risk.
 
  The Company manages this risk by monitoring its ratio of fixed and variable
rate debt obligations in view of changing market conditions and from time to
time altering that ratio by, for example, refinancing balances outstanding
under its variable rate bank credit facilities with fixed-rate debt or by
entering into interest rate swap agreements.
 
  As of December 31, 1998 the Company had $60.0 million (NOK 455.0 million) in
variable rate, Norwegian denominated debt. The Company has entered into an
interest rate swap agreement in order to manage its interest rate exposure on
this debt. The agreement requires the Company to pay a fixed rate of interest
on a notional amount of principal to a counterparty. The counterparty, in
turn, pays the Company a variable rate of interest on the same notional amount
of principal. The effect of the swap is to limit the interest rate exposure to
a fixed percentage on the related debt obligation.
 
  As of December 31, 1998, the carrying value of the Company's long-term fixed
rate debt, including accrued interest, was approximately $303.7 million, which
included the Notes ($289.9 million), the Ship Bonds ($10.2 million) and the
Norwegian fixed rate debt ($3.6 million). The fair value of this debt was
approximately $253.4 million. Fair value was determined using quoted market
prices, where available, or discounted future cash flows based on the
Company's current incremental borrowing rates for similar types of borrowing
arrangements as of the balance sheet date. A hypothetical 1% increase in the
applicable interest rates would decrease the fair value of the Company's long-
term fixed rate debt by approximately $9.3 million. The hypothetical fair
values are based on the same assumptions utilized in computing fair values at
December 31, 1998.
 
  As of December 31, 1998, the carrying value of the Company's long-term
variable rate debt, including accrued interest, was approximately $111.5
million and included the Company's Bank Credit Facility and the Saevik Bank
Facility. The fair value of this debt approximates the carrying value because
the interest rates are based on floating rates identified by reference to
market rates. A hypothetical 1% increase in the applicable interest rates
would increase interest expense by approximately $1.1 million.
 
  As of December 31, 1998, the Company's interest rate swap agreement had a
fair value of $179,000 based on estimated amounts that the Company would
receive or pay to terminate the contract at the reporting date. A hypothetical
1% increase in the pay rate would result in an increase in interest expense of
approximately $264,000. A hypothetical 1% increase in the receive rate would
decrease interest expense by a corresponding amount.
 
Foreign Currency Exchange Rate Sensitivity
 
  The Company's foreign subsidiaries collect revenues and pay expenses in
several different foreign currencies. The Company monitors the exchange rate
of its foreign currencies and, when deemed appropriate, entries into hedging
transactions in order to mitigate the risk from foreign currency fluctuations.
The Company also manages its foreign currency risk by attempting to contract
foreign revenue in U.S. Dollars whenever practicable.
 
  The Company has exposure to fluctuations in foreign currency exchange rates
resulting from several of its Norwegian vessels operating in the United
Kingdom under long-term contracts denominated in the Great Britain Pound
(GBP). As of December 31, 1998, the Company had approximately $7.1 million of
firmly committed sales contracts through December 31, 1999, denominated in the
GBP. A hypothetical 10% increase in the applicable exchange rates would result
in an increase in future cash flows of approximately $706,000. A 10% decrease
would result in a corresponding decrease in future cash flows. The Company
manages this risk through the use of foreign currency forward exchange
contracts.
 
                                      21
<PAGE>
 
  The Company's foreign currency forward exchange contracts would offset the
resulting increases/decreases in cash flows generated by exchange rate
fluctuations of firmly committed sales contracts. A hypothetical 10% increase
in the applicable exchange rates would result in approximately $918,000
decrease in future cash flows. A 10% decrease would result in a corresponding
increase in future cash flows. Foreign currency forward exchange contracts had
a fair value of $139,000 as of December 31, 1998. Fair value is estimated by
obtaining quotes from brokers.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. The Company:
 
  Trico Marine Services, Inc. (the "Company") is a leading provider of marine
support vessels and related services to the oil and gas industry in the U.S.
Gulf of Mexico (the "Gulf"), offshore Brazil and the North Sea. The Company is
the second largest owner and operator of supply boats in the Gulf and a
leading operator in the North Sea. At December 31, 1998, the Company had a
total fleet of 99 vessels, including 54 supply vessels, 11 large capacity
platform supply vessels ("PSV"), six large anchor handling, towing and supply
vessels ("AHTS"), 13 crew boats, six lift boats and nine line-handling
vessels. The services provided by the Company's diversified fleet include
transportation of drilling materials, supplies and crews to offshore
facilities and support for the construction, installation, maintenance and
removal of those facilities.
 
  The Company's financial position, results of operations and cash flows are
affected primarily by day rates and fleet utilization in the Gulf of Mexico
and the North Sea which primarily depend on the level of drilling activity,
which ultimately is dependent upon both short-term and long-term trends in oil
and natural gas prices.
 
2. Summary of Significant Accounting Policies:
 
 Consolidation Policy
 
  The consolidated financial statements include the Company and its
subsidiaries, including wholly-owned Trico Marine Assets, Inc. ("Trico
Assets"), Trico Marine Operators, Inc. ("Trico Operators"), Saevik Supply, ASA
("Saevik") which was acquired December 1, 1997, and Trico Servicos Maritimos,
Ltd. ("TSM") which became wholly-owned effective July 1, 1998. Prior to July
1, 1998 the Company's 40% investment in TSM was accounted for using the equity
method. (See Note 3). All significant intercompany accounts and transactions
have been eliminated.
 
 Cash and Cash Equivalents
 
  All highly liquid debt instruments with original maturity dates of three
months or less are considered to be cash equivalents.
 
 Property and Equipment
 
  Marine vessels, transportation and other equipment are stated at cost.
Depreciation for financial statement purposes is provided on the straight-line
method, assuming 10% salvage value for marine vessels. Marine vessels are
depreciated over a useful life of fifteen to thirty years from the date of
acquisition. Buildings and improvements are depreciated over a useful life of
fifteen to forty years. Major modifications which extend the useful life of
marine vessels are capitalized and amortized over the adjusted remaining
useful life of the vessel. When assets are retired or disposed, the cost and
accumulated depreciation thereon are removed and any resultant gains or losses
are recognized in current operations. Depreciation expense amounted to
approximately $26,286,000, $12,378,000 and $4,478,000 in 1998, 1997 and 1996,
respectively.
 
  Interest is capitalized in connection with the construction of vessels. The
capitalized interest is recorded as part of the asset to which it relates and
is amortized over the asset's estimated useful life. In 1998 and 1997,
$3,271,000 and $421,000 of interest was capitalized, respectively. No interest
was capitalized in 1996.
 
  Marine vessel spare parts are stated at average cost.
 
  Drydocking expenditures incurred in connection with marine inspections are
capitalized and amortized on a straight-line basis over the period to be
benefited (generally 24 to 36 months).
 
 Deferred Financing Costs
 
  Deferred financing costs include costs associated with the issuance of the
Company's debt and are amortized on a straight-line basis over the life of the
related debt agreement.

 Goodwill
 
  Goodwill, or cost in excess of fair value of the net assets of companies
acquired, is amortized on a straight-line basis over 8 to 37.5 years. On an
annual basis, the Company reviews the recoverability of goodwill based
primarily upon an analysis of undiscounted cash flows from the acquired
businesses. Accumulated amortization amounted to approximately $3,642,000 and
$399,000 at December 31, 1998 and 1997, respectively.
 
 Income Taxes
 
  The Company accounts for income taxes using the provisions of Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS
No. 109"). Deferred income taxes are provided at the currently enacted income
tax rates for the difference between the financial statement and income tax
bases of assets and liabilities and carryforward items.
 
 Revenue and Expense Recognition
 
  Charter revenue is earned and recognized on a daily rate basis. Operating
costs are expensed as incurred.
 
 Direct Vessel Operating Expenses
 
  Direct vessel operating expenses principally include crew costs, insurance,
repairs and maintenance, management fees, and casualty losses.
 
 Foreign Currency Translation
 
  All assets and liabilities of the Company's foreign subsidiaries are
translated into U.S. dollars at the exchange rate in effect at the end of the
period, and revenue and expenses are translated at weighted average exchange
rates prevailing during the period. The resulting translation adjustments are
reflected within the stockholders' equity component, accumulated other
comprehensive loss.
 
 Stock Compensation
 
  On January 1, 1996, the Company elected to continue to use the intrinsic
value method of accounting for stock-based compensation prescribed by
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" ("APB 25") and, accordingly, adopted only the disclosure provisions
of Statement of Financial Accounting Standards No. 123 "Accounting for Stock-
based Compensation" ("SFAS No. 123").
 
 Earnings Per Share
 
  Basic earnings per share excludes dilution and is computed by dividing
income available to common stockholders by the weighted-average number of
common shares outstanding for the period. Diluted earnings per share reflects
the potential dilution that could occur if securities or other contracts to
issue common stock were exercised or converted into common stock or resulted
in the issuance of common stock that then shared in the earnings of the
Company.
 
 Authorized Shares and Stock Splits
 
  On April 26, 1996, the Company's Board of Directors approved a 3.0253-for-1
split of the Company's common stock in the form of a stock dividend. The
financial statements have been restated to reflect the effects of this stock
split, including all share amounts and per share data.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
 
  On May 22, 1997, the Company's stockholders approved an amendment to the
Company's Certificate of Incorporation to increase the number of shares of
common stock which the Company is authorized to issue from 15 million to 40
million (the "Amendment"). A two-for-one split of the Company's common stock
in the form of a 100% stock dividend that was previously declared by the
Company's Board of Directors, subject to approval of the Amendment by the
Company's stockholders, was paid on June 9, 1997. The financial statements
have been restated to reflect the effects of this stock split, including all
share amounts and per share data.
 
 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 reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 New Accounting Standards
 
  During the year, the Company adopted Statement of Financial Accounting
Standards, No. 130, "Reporting Comprehensive Income" ("SFAS No. 130"). SFAS
No. 130 requires the reporting of comprehensive income in addition to net
income from operations. Comprehensive income is a more inclusive financial
reporting methodology that includes disclosures of certain financial
information that historically has not been recognized in the calculation of
net income. Prior periods presented herein have been reclassified in
accordance with SFAS No. 130.
 
  The Company also adopted Statement of Financial Accounting Standards No.
131, "Disclosures About Segments of an Enterprise and Related Information"
("SFAS No. 131") and No. 132, "Employers' Disclosures About Pensions and Other
Postretirement Benefits" ("SFAS No. 132"). SFAS No. 131 establishes standards
for the way enterprises report information about operating segments and
related disclosures about products and services, geographic areas and major
customers. SFAS No. 132 revises employers' disclosures about pension and other
postretirement benefit plans. It does not change the measurement or
recognition of these plans.
 
  In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards, No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS No. 133"), effective for all fiscal
quarters of fiscal years beginning after June 15, 1999. The Company is
currently evaluating the impact SFAS No. 133 will have on its financial
statements, if any.
 
 Reclassifications
 
  Certain prior-period amounts have been reclassified to conform with the
presentation shown in the current year's financial statements. These
reclassifications had no effect on net income, total stockholders' equity or
cash flows.
 
3. Acquisitions:
 
 Saevik Acquisition
 
  On December 1, 1997, the Company acquired approximately 99% of the
outstanding shares of Saevik Supply ASA, a publicly traded Norwegian company
("Saevik") for approximately $293,654,000, including transaction costs.
Subsequent to December 31, 1997, the Company acquired the remaining
outstanding shares of Saevik. Saevik provides marine support and
transportation services to companies engaged in offshore exploration and
production of oil and gas in the North Sea.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
 
  The acquisition has been accounted for by the purchase method, and Saevik's

from the date of acquisition. Goodwill of $118,310,000 was recorded in
conjunction with the purchase of Saevik. The goodwill is being amortized over
37.5 years.
 
  The effect of the acquisition of Saevik at the date of purchase on the
consolidated financial statements was as follows for the year ended December
31, 1997 (in thousands):

 TSM Acquisition
 
  On March 15, 1996, the Company acquired seven line handling vessels and a
40% interest in TSM, a marine operating company located in Brazil, for a
combined price of $4,200,000. TSM owned an eighth line handling vessel and
operated it and the seven other acquired vessels under long-term contracts
with a customer located in Brazil. Of the purchase price, $3,565,000 was
allocated to the acquired vessels based upon their relative fair value,
$270,000 was allocated to the Company's investment in the stock of TSM with
the remaining $365,000 allocated to goodwill. In addition to the purchase
price above, $300,000 of contingent purchase price was paid on August 27, 1996
based upon the attainment by the Company of a certain contract to provide
offshore marine services in Brazil. This amount has been recorded as
additional goodwill. An additional $119,000 was recorded as goodwill in 1997
relating to the realization of certain acquired assets and liabilities. Prior

  In June 1997 the Company entered into an agreement to acquire 12 supply
vessels for $69,000,000. Eleven of the vessels were acquired for a total of

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
 
  During 1995, the Company had a revolving credit and term loan agreement with
BankBoston (the "Credit Agreement"). Availability under the revolving loan was
based on the Company's accounts receivable. Substantially all of the Company's
assets served as collateral for the Credit Agreement.
 
  Effective June 28, 1995, the Company amended its Credit Agreement ("Second
Amendment") to establish $5,000,000 of availability under the revolving credit
loan and extend principal payments. Under the Second Amendment, the Company
had the right to convert $2,000,000 of outstanding amounts under the revolving
credit loan into a term loan. The Company converted $1,700,000 of its
outstanding revolving credit loan into a term loan in November 1995 and
$300,000 of amounts outstanding under the revolving credit loan were converted
into a term loan in January 1996.
 
  Effective March 6, 1996, the Company amended its Credit Agreement ("Third
Amendment") to provide for an increased total credit facility, extend
principal payments and restructure other portions of the Credit Agreement. The
Third Amendment contained a revolving credit facility and term loan
provisions. The $3,000,000 revolving credit facility, which would have matured
in July 1997, bore interest at 1.75% above a base rate. The Third Amendment
contained $33,000,000 of term loans in three separate tranches which all bore
interest at 1.75% above a base rate.
 
  The outstanding principal balance of the Credit Agreement of $31,150,000 was
repaid on May 21, 1996, together with a prepayment fee of $75,000, from the
proceeds of the Company's initial public offering of common stock. The balance
of $6,065,000 of the Company's 9% Subordinated Notes and accrued interest
thereon was also retired with proceeds from the initial public offering. As a
result of the prepayment of all of the Company's senior and subordinated debt,
the Company recorded an extraordinary charge of $917,000, net of taxes of
$494,000, for the write-off of the unamortized balance of related debt
issuance costs.
 
  Effective July 26, 1996, the Company executed a new $30,000,000 revolving
credit agreement (the "Bank Credit Facility") with the same group of lenders
that provided the Company's previous Credit Agreement, which was prepaid on
May 21, 1996 with proceeds from the initial public offering. The Bank Credit
Facility was increased to $35,000,000 effective August 26, 1996 and to
$50,000,000 effective October 8, 1996. The Bank Credit Facility bore interest
at LIBOR plus 1 1/2% per annum with a commitment fee of 3/8% per annum on the
undrawn portion. The Bank Credit Facility contained certain covenants which
required the Company to maintain certain debt coverage ratios and net worth
levels, limit capital expenditures and prohibit equity distributions.
 
  In connection with the acquisition of Saevik, on December 1, 1997, the
Company amended and restated the Bank Credit Facility to provide for a
$150,000,000 revolving line of credit and $200,000,000 in term loans (the
"Amended and Restated Facility"). The Amended and Restated Facility matures
December 1, 2002 and bears interest at a Eurocurrency rate plus a margin that
depends on the Company's leverage ratio with a commitment fee of .25% to .5%
on the undrawn portion. The Amended and Restated Facility was collateralized,
to the extent permitted by the indentures that govern the Senior Notes (as
defined herein), by a security interest in substantially all of the assets of
the Company's subsidiaries and a pledge of the stock of certain of the
Company's subsidiaries. The Amended and Restated Facility contains certain
covenants which require the Company to maintain certain debt coverage ratios
and minimum net worth and which restrict the Company's ability to incur
additional indebtedness, pay dividends or make certain other distributions.
The Amended and Restated Facility may be used to borrow in U.S. Dollars or
Norwegian Kroner.
 
  During 1998, the Amended and Restated Facility was amended to reduce
permitted borrowings to $85,000,000, increasing to $100,000,000 after June 30,
1999, depending upon the Company's leverage ratio, and to reduce the
collateral requirements to certain U.S. flag vessels and related assets.

  During 1997, the Company issued three Series of 8 1/2% Senior Notes due
2005, Series A/B Notes--$110,000,000, Series C/D Notes--$100,000,000 and
Series E/F Notes--$70,000,000 (the "Senior Notes"). The Senior Notes are
uncollateralized and are required to be guaranteed by all of the Company's
Significant Subsidiaries (as such term is defined in the Indentures that
govern the Senior Notes). Interest on the Senior Notes is payable semi-
annually on February 1 and August 1 of each year commencing February 1, 1998.
Except in certain circumstances the Senior Notes may not be prepaid until
August 1, 2001, at which time they may be redeemed, at the option of the
Company, in whole or in part, at a redemption price equal to 104.25%, plus
accrued and unpaid interest, with the redemption price declining ratably on
August 1 of each of the succeeding three years. No sinking fund payments are
required on the Senior Notes until their final maturity. In November 1998, the
Company combined the A/B, C/D and E/F Series Notes, which comprise the Senior
Notes, into one series known as the Series G Notes. The terms and conditions
of the Series G Notes are identical to the predecessor Senior Notes. The
Senior Notes contain certain covenants that, among other things, limit the
ability of the Company to incur additional indebtedness, pay dividends or make
other distributions, create certain liens, sell assets, or enter into certain
mergers or acquisitions.
 
  In April 1998, the Company issued $10,000,000 principal amount of eight year
United States Government Guaranteed Ship Financing Bonds, SWATH Series I, at
an interest rate of 6.08% (the "Bonds"). The Bonds are due in 16 semi-annual
installments of principal and interest. The Bonds are collateralized by a
first preferred ship mortgage on the Stillwater River, a small waterplane area
twin hull ("SWATH") vessel, and by an assignment of the charter contract that
the vessel commenced upon its completion. The proceeds from the Bonds were
released to the Company upon completion and delivery of the vessel in November
1998.
 
  In June of 1998, the Company refinanced a significant portion of its debt,
which was held at the Saevik level and due to a certain lender, into a single
NOK 650,000,000 ($85,755,000) revolving credit facility (the "Saevik Bank
Facility") bearing interest at NIBOR plus .75%, which reduces in ten
semiannual installments of NOK 50,000,000 ($6,597,000) and one balloon payment
of NOK 150,000,000 ($19,800,000), due at maturity in June 2003. The Saevik
Bank Facility is collateralized by a security interest in certain of the
Company's North Sea vessels and requires Saevik to maintain certain financial
ratios and limits the ability of Saevik to create liens or merge or
consolidate with other entities.
 
  The Company has a pending application and expects to receive a commitment
from the U.S. Maritime Administration's Title XI ship financing program to
provide long-term financing for two vessels, the Spirit River and the Hondo
River. The Spirit River was delivered in December 1998 and the Hondo River is
scheduled to be delivered in the second quarter of 1999.
 
8. Financial Instruments:
 
  During 1998, the Company entered into several foreign currency forward
exchange contracts to hedge certain exposures relating to currency
fluctuations between the Norwegian Kroner and the Great Britain Pound
resulting from several of the Saevik vessels operating in the United Kingdom
under long-term contracts denominated in the Great Britain Pound. As of
December 31, 1998, the Company had foreign currency forward exchange contracts
outstanding of approximately $9,272,000. These foreign currency forward
exchange contracts expire at various points through December 31, 1999. Gains
and losses on the contracts are deferred until the hedged transaction is
completed. As of December 31, 1998, losses of $102,000 were recognized on
completed foreign currency forward exchange contracts. Deferred gains of
approximately $54,000 were included in the consolidated balance as accrued
expenses at December 31, 1998. The foreign currency forward exchange contracts
had a fair value of $139,000 at December 31, 1998.
 
  During 1998, the Company entered into a swap agreement expiring in June
2003, with an aggregate notional amount of NOK 200,000,000 ($26,400,000). The
agreement requires the Company to pay a fixed rate of interest on the notional
amount, and the Company, in turn, receives a variable rate of interest on the
same notional amount. The effect of the swap agreement is to limit the
interest rate exposure to 5.7% on NOK 200,000,000 ($26,400,000) of the Saevik
Bank Facility. Amounts to be paid or received under the swap agreement

are accrued as interest rate changes and are recognized over the life of the
agreement as an adjustment to interest expense. As a result of this swap
agreement, interest expense was increased by approximately NOK 1,500,000
($198,000) in 1998. The estimated fair value of the interest rate swap as of
December 31, 1998 was NOK 1,360,000 ($179,000).

  The Company has not recognized a deferred tax liability of approximately
$2,642,000 for the undistributed earnings of a non-U.S. subsidiary because the
Company currently does not expect those unremitted earnings to reverse and
become taxable to the Company in the foreseeable future. A deferred tax
liability will be recognized when the Company expects that it will realize
those undistributed earnings in a taxable manner, such as through receipt of
dividends or sale of investments. As of December 31, 1998, the undistributed
earnings of this subsidiary were approximately $37,743,000.

a change of control for federal income tax purposes. This will limit the
utilization of approximately $14,500,000 of net operating loss carryforwards
to a set level as provided by regulations.

10. Preferred Stock:
 
  In February 1998, the Company's Board of Directors approved the adoption of
a Stockholder Rights Plan ("Plan"). In connection with the Plan, the Board of
Directors approved the authorization of 100,000 shares of $0.01 par value
preferred stock, designated the Series AA Participating Cumulative Preference
Stock. Under the Plan, Preference Stock Purchase Rights (the "Rights") will be
distributed as a dividend at a rate of one Right for each share of the
Company's common stock held as of record as of the close of business on March
6, 1998. Each Right will entitle holders of the Company's common stock to buy
a fraction of a share of the new series of the Company's preferred stock at an
exercise price of $105. The Rights will become exercisable and detach from the
common stock, only if a person or group, with certain exceptions, acquires 15%
or more of the outstanding common stock, or announces a tender or exchange
offer that, if consummated would result in a person or group beneficially
owning 15% or more of outstanding common stock. Once exercisable, each Right
will entitle the holder (other than the acquiring person) to acquire common
stock with a value of twice the exercise price of the Rights. The Company will
generally be able to redeem the Rights at $0.01 per Right at any time until
the close of business on the tenth day after the Rights become exercisable.
 
11. Common Stock Option Plans:
 
  The Company sponsors two stock-based incentive compensation plans, the "1993
Stock Option Plan" (the "1993 Plan") and the "1996 Stock Incentive Plan" (the
"1996 Plan"). Statement of Financial Accounting Standards No. 123 "Accounting
for Stock-Based Compensation" ("SFAS No. 123") became effective for the
Company in 1996. As allowed by SFAS No. 123, the Company has elected to
continue to follow Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" ("APB 25") in accounting for its stock option
plans. Under APB 25, the Company does not recognize compensation expense on
the issuance of its stock options because the option terms are fixed and the
exercise price equals the market price of the underlying stock on the grant
date.
 
  Under the 1993 Plan, the Company is authorized to issue shares of common
stock pursuant to "Awards" granted in the form of incentive stock options
(qualified under Section 422 of the Internal Revenue Code of 1986, as amended)
and non-qualified stock options. Awards may be granted to key employees of the
Company. The Compensation Committee administers the Plan and has broad
discretion in selecting Plan participants and determining the vesting period
and other terms applicable to Awards granted under the Plan.
 
  According to the 1993 Plan, Awards may be granted with respect to a maximum
of 1,455,018 shares of common stock. As of December 31, 1996, Awards have been
granted with respect to all 1,455,018 shares. All these Awards have a ten-year
term and are fully exercisable. As of December 31, 1998 there were 1,043,480
options outstanding under the 1993 Plan.
 
  Under the 1996 Plan, the Company is authorized to issue shares of common
stock pursuant to "Awards" granted in the form of incentive stock options
(qualified under Section 422 to the Internal Revenue Code of 1986, as
amended), non-qualified stock options, restricted stock, stock awards, or any
combination of these forms of Awards. Awards may be granted to key employees
of the Company, including directors who are also considered employees of the
Company for purposes of the Plan. The Compensation Committee administers the
Plan and has broad discretion in selecting Plan participants and determining
the vesting period and other terms applicable to Awards granted under the
Plan.
 
  According to the 1996 Plan, Awards may be granted with respect to a maximum
of 900,000 shares of common stock. No participant may be granted, in any
calendar year, Awards with respect to more than 100,000 shares of common
stock. In 1996, the Company granted a total of 221,000 Awards in the form of
incentive stock options under the Plan at exercise prices equal to the fair
value of the Company's stock at that time, which ranged from $8.00 to $10.94
per share. The Awards have a ten-year term and vested in the

first year following their grant, except for 15,000 awards which were 25%
vested at the date of grant and vest in annual increments of 25% over the
three years following their grant.
 
  In 1997, the Company granted 191,000 Awards in the form of incentive stock
options under the 1996 Plan at exercise prices equal to the fair value of the
Company's stock at that time which ranged from $20.13 to $23.13 per share. The
Awards have a ten-year term and vest in annual increments of 25% over the four
years following their grant, except for 18,000 awards which vested at the date
of grant.
 
  During 1998, the Company granted 218,500 Awards in the form of incentive
stock options under the 1996 Plan at exercise prices equal to the fair value
of the Company's stock at that time which ranged from $6.63 to $19.50. The
Awards expire in 10 years and vest in annual increments of 25% over the four
years following their grant, except for 8,000 awards which vested at the date
of grant.
 
  As of December 31, 1998, there were 562,375 options outstanding under the
1996 Plan.

  Weighted average fair value of options granted during 1998, 1997 and 1996
were $7.05, $9.30 and $4.25, respectively.
 
  The fair value of each stock option granted is estimated on the date of
grant using the minimum value method of option pricing with the following
weighted-average assumptions for grants in 1998, 1997, 1996, respectively: no
dividend yield; risk-free interest rates are 5.56%, 6.40% and 6.56%, expected
terms of the options are 5 to 6 years; and the expected volatility is 38.54%,
39.35% and 43.91%.

  Options to purchase 562,375 shares of common stock at prices ranging from
$6.63 to $23.13 were outstanding during 1998 but were not always included in
the computation of diluted earnings per share because the options' exercise
prices were greater than the average market price of common shares at certain
points during the year. The options were still outstanding at the end of 1998.
 
13. Other Related Party Transactions:
 
  Pursuant to an agreement effective October 29, 1993, Berkshire Partners, a
shareholder, was entitled to receive $16,666 each month for five years for
providing certain management and other consulting services (the "Berkshire
Agreement"). The Berkshire Agreement was automatically renewable on an annual
basis after the initial five year period upon agreement of the parties. The
Berkshire Agreement was terminated upon the successful completion of the
Company's initial public offering in May 1996.
 
14. Employee Benefit Plans:
 
 Profit Sharing Plan
 
  The Company has a defined contribution profit sharing plan under Section
401(k) of the Internal Revenue Code (the "Plan") that covers substantially all
U.S. employees meeting certain eligibility requirements. Employees may
contribute up to 15% (subject to certain ERISA limitations) of their eligible
compensation on a

pre-tax basis. The Company will match 25% of the participants' before tax
savings contributions up to 5% of the participants' taxable wages or salary.
The Company may also make a matching contribution to the Plan at its
discretion. The Company expensed contributions to the Plan for the years ended
December 31, 1998, 1997 and 1996 of $255,000, $129,000 and $113,000,
respectively.
 
 Pension Plan and Employee Benefits:
 
  Substantially all of the Company's Norwegian and United Kingdom employees
are covered by a number of noncontributory, defined benefit pension plans
which were acquired in association with the acquisition of Saevik. Benefits
are based primarily on participants' compensation and years of credited
services. The Company's policy is to fund contributions to the plans based
upon actuarial computations. Plan assets include investments in debt and
equity securities and property.

  The projected benefit obligation, accumulated benefit obligation, and fair
value of plan assets for the pension plan with accumulated benefit obligations
in excess of plan assets were $656,000, $492,000 and $364,000, respectively,
as of December 31, 1998.
 
15. Commitment and Contingencies:
 
  The Company has an agreement with an unrelated company to provide management
and operating services for certain lift boats. The agreement provides for
management and incentive fees to be paid to the unrelated company based on
percentages of gross monthly income and net operating income, respectively.
Management fees of $1,143,000, $1,271,000 and $979,000 were included in direct
vessel operating expenses for the years ended December 31, 1998, 1997 and
1996, respectively. Pursuant to the agreement, the operator has been granted a
right of first refusal on any sale of the lift boats.
 
  In the ordinary course of business, the Company is involved in certain
personal injury, pollution and property damage claims and related threatened
or pending legal proceedings. Management, after review with legal counsel and
insurance representatives, is of the opinion these claims and legal
proceedings will be settled within the limits of the Company's insurance
coverages. At December 31, 1998 and 1997, the Company has accrued a liability
in the amount of $1,997,000 and $1,560,000, respectively, based upon the
insurance deductibles that management believes it may be responsible for
paying in connection with these matters. The amounts the Company will
ultimately be responsible for paying in connection with these matters could
differ materially in the near term from amounts accrued.
 
  During 1997, Saevik commenced construction of a 275-foot, technologically
advanced anchor handling, towing and supply vessel ("AHTS"), with 23,800
horsepower that is scheduled to be delivered in June 1999. Also, the Company
began construction during 1997 of the Hondo River, a 230-foot offshore supply
vessel that is scheduled to be delivered in the second quarter of 1999. Total
remaining committed costs of the two vessels are expected to be approximately
$24,454,000.
 
16. Fair Value of Financial Instruments:
 
  The estimated fair values of financial instruments have been determined by
the Company using available market information and valuation methodologies
described below. However, considerable judgment is required in interpreting
market data to develop the estimates of fair value. Accordingly, the estimates
presented herein may not be indicative of the amounts that the Company could
realize in a current market exchange. The use of different market assumptions
or valuation methodologies may have a material effect on the estimated fair
value amounts.
 
  Cash and cash equivalents: The carrying amounts approximate fair value due
to the short-term nature of these instruments.
 
  Long-term debt: The carrying amounts of the Company's variable rate debt
approximate fair value because the interest rates are based on floating rates
identified by reference to market rates. The fair value of the Company's fixed
rate debt is based on quoted market prices, where available, or discounted
future cash flows based on the Company's current incremental borrowing rates
for similar types of borrowing arrangements as of the balance sheet date. The
carrying amounts and fair values of long-term debt, including accrued
interest, as of December 31, 1998 and 1997 were as follows:

18. Segment and Geographic Information (In Thousands):
 
  The Company is a provider of marine supply vessels and related services to
the oil and gas industry. Substantially all revenues result from the charter
of vessels owned by the Company. The Company's three reportable segments are
based on geographic area, consistent with the Company's management structure.
The accounting policies of the segments are the same as those described in the
summary of significant accounting policies except for purposes of income taxes
and intercompany transactions and balances. The North Sea segment provides for
a flat tax rate of 28% which is the Norwegian statutory tax rate.
Additionally, segment data includes intersegment revenues, receivables and
payables, and investments in consolidated subsidiaries. The Company evaluates
performance based on net income (loss). The U.S. segment represents the
domestic operations, the North Sea segment includes Norway and the United
Kingdom, and the Other segment includes primarily Brazil. Long-term debt and
the related interest expense associated with the acquisitions of foreign
subsidiaries are reflected in the U.S. segment. Segment data as of and for the
years ended December 31, 1998, 1997 and 1996 are as follows:

  For the year ended December 31, 1998, revenues from one customer of the
Company's North Sea segment represents approximately $29,757,000, or $16%, of
the Company's consolidated revenues. For the years ended December 31, 1997 and
1996, no customer accounted for more than 10% of the Company's revenues.
 
19. Separate Financial Statements For Subsidiary Guarantors:
 
  Pursuant to the terms of the indentures governing the Senior Notes, the
Senior Notes must be guaranteed by each of the Company's "significant
subsidiaries" (the "Subsidiary Guarantors"), whether such subsidiary was a
"significant subsidiary" at the time of the issuance of the Senior Notes or
becomes a "significant subsidiary" thereafter. Separate financial statements
of the Subsidiary Guarantors are not included in this report because (a) the
Company is a holding company with no assets or operations other than its
investments in its subsidiaries, (b) the Subsidiary Guarantors are wholly-
owned subsidiaries of the Company, comprise all of the Company's direct and
indirect subsidiaries (other than inconsequential subsidiaries) and, on a
consolidated basis, represent substantially all of the assets, liabilities,
earnings and equity of the Company, (c) each of the Subsidiary Guarantors must
fully and unconditionally guarantee the Company's obligations under the Senior
Notes on a joint and several basis (subject to a standard fraudulent
conveyance savings clause) and (d) management has determined that separate
financial statements and disclosures concerning the Subsidiary Guarantors are
not material to investors. During 1998, Saevik and its wholly-owned
subsidiary, Saevik Shipping, AS, executed guarantees of the Senior Notes that
were deemed to be effective December 2, 1997.
