  Certain technical terms are defined in the "Glossary of Certain Technical
Terms" appearing at the end of this Report.
 
GENERAL
 
  Gulf Island Fabrication, Inc. (together with its subsidiaries, the
"Company") is a leading fabricator of offshore drilling and production
platforms and other specialized structures used in the development and
production of offshore oil and gas reserves. Structures and equipment
fabricated by the Company include jackets and deck sections of fixed
production platforms, hull and deck sections of floating production platforms
(such as tension leg platforms ("TLPs")), piles, wellhead protectors, subsea
templates and various production, compressor and utility modules. The Company
believes it is one of only three domestic companies capable of fabricating
fixed offshore production platforms, including jackets, for installation in
water depths greater than 300 feet. The Company's focus on controlling costs
and providing high quality, reliable products and services has enabled it to
be profitable for each year since 1988.
 
  Demand for the Company's products and services is primarily a function of
the level of offshore oil and gas activity in the Gulf of Mexico and, to a
lesser extent, offshore areas in West Africa and Latin America. The Company
believes that the number of acreage blocks leased by oil and gas companies in
the Gulf of Mexico and the number of active drilling rigs in the Gulf of
Mexico are leading indicators of demand for the Company's products, with
fabricating activity trailing leasing and drilling activity by one to three
years. Over the past five years, improvements in seismic and drilling
technology, production techniques and oil and gas prices have resulted in an
increased number of acreage blocks leased, more intensive drilling activity in
shallow water areas, and increased exploration of deepwater areas of the Gulf
of Mexico. As a result, demand for the Company's products improved.
 
  The Company was founded in 1985 by a group of investors, including Alden J.
"Doc" Laborde and Huey J. Wilson, and began operations at its fabrication yard
on the Houma Navigation Canal in Southern Louisiana, approximately 30 miles
from the Gulf of Mexico. On January 2, 1997, Gulf Island Fabrication, Inc.
acquired Dolphin Services, Inc. and two related companies (collectively,
"Dolphin Services"), which perform offshore and inshore fabrication and
construction services (the "Dolphin Acquisition"), and in April 1997,
completed the initial public offering (the "Initial Public Offering") of its
common stock, no par value per share (the "Common Stock"). The Company's
primary facilities are located on 597 acres, of which 250 are currently
developed for fabrication activities with 347 acres available for future
expansion. These facilities allow the Company to build jackets for
installation in water depth of up to 800 feet and deck sections for fixed or
floating production platforms for use in unlimited water depth. In addition,
the Company is able to build certain hull sections of tension leg platforms,
typically for use in water depth greater than 1,000 feet.
 
  Effective January 1, 1998, the Company acquired all of the outstanding stock
of Southport, Inc. and its wholly owned subsidiary Southport International,
Inc. (collectively, "Southport"). Southport specializes in the fabrication of
living quarters for offshore platforms. The purchase price was $6.0 million
cash, plus contingent payments of up to an additional $5.0 million based on
Southport's net income over a four-year period ending December 31, 2001.
 
DESCRIPTION OF OPERATIONS
 
  The Company's primary activity is the fabrication of offshore drilling and
production platforms, including jackets and deck sections of fixed production
platforms, hull and deck sections of floating production platforms (such as
TLPs), piles, wellhead protectors, subsea templates and various production,
compressor and utility modules. The Company also has the ability to produce
and repair pressure vessels used in the oil and gas
 
                                       1
<PAGE>
 
industry, refurbish existing platforms and fabricate various other types of
steel structures. With its acquisition of Southport, the Company has also
increased its presence in the market for the fabrication of living quarters
for installation on such platforms.
 
  The Company uses the latest welding and fabrication technology available,
and all of the Company's products are manufactured in accordance with industry
standards and specifications, including those published by the American
Petroleum Institute, the American Welding Society and the American Society of
Mechanical Engineers. The Company has also been certified as an ISO 9002
fabricator for its quality assurance programs. See "-- Safety and Quality
Assurance."
 
  Fabrication of Offshore Platforms. The Company fabricates structural
components of fixed platforms for use in the offshore development and
production of oil and gas. A fixed platform is the traditional type of
platform used for the offshore development and production of oil and gas,
although recently there has been an increase in the use of floating production
platforms and TLPs as a result of increased drilling and production activities
in deeper waters. Most fixed platforms built today can accommodate both
drilling and production operations. These combination platforms are large and
generally more costly than single-purpose structures. However, because
directional drilling techniques permit a number of wells to be drilled from a
single platform and because drilling and production can take place
simultaneously, combination platforms are often more cost effective.
 
  The most common type of fixed platform consists of a jacket (a tubular
steel, braced structure extending from the mudline on the seabed to a point
above the water surface) which is supported on tubular pilings driven deep
into the seabed and supports the deck structure located above the level of
storm waves. The deck structure, extending above the surface of the water and
attached to the top end of the jacket, is designed to accommodate multiple
functions, including drilling, production, separating, gathering, piping,
compression, well support and crew quartering. Platforms can be joined by
bridges to form complexes of platforms for very large developments or to
improve safety by dividing functions among specialized platforms. Jacket-type
platforms are generally the most viable solution for water depths of 1,000
feet or less. Although there is no height limit to the size of the jackets
that can be fabricated at the Company's facilities, the dimensions of the
Houma Navigation Canal prevent the transportation to the Gulf of Mexico of
most jackets designed for water depths exceeding 800 feet. The Company can,
however, build decks, piping and equipment modules, living quarters, piles and
other components of platforms for installation in any water depth. Often,
customers split projects among fabricators, contracting with different
companies for the fabrication of the jacket, deck sections, living quarters
and piles for the same platform. Therefore, the Company is able, through the
construction of decks, living quarters and piles, to participate in the
construction of platforms requiring jackets that are larger than those the
Company can transport through the Houma Navigation Canal.
 
  Most of the steel used in the Company's operations arrives at the Company's
fabrication yards as steel plate. The plate is cut and rolled into tubular
sections at rolling mills in the fabrication yards. The tubular sections
(which vary in diameter, up to 12 feet) are welded together in long straight
tubes to become legs or into shorter tubes to become part of the network of
bracing that supports the legs. Various cuts and welds in the fabrication
process are made by computer-controlled equipment that operates from data
developed during the design of the structure. The Company's ability to
fabricate and assemble the large tubular sections needed for jackets built for
use in water depths over 300 feet distinguish the Company from all but two of
its domestic competitors.
 
  Jackets are built on skidways (which are long parallel rails along which the
jacket will slide when it is transferred to a barge for towing out to sea) and
are generally built in sections so that, to the extent possible, much of their
fabrication is done on the ground. As each section of legs and bracing is
complete, large crawler cranes pick up an entire side and "roll up" the
section, which is then joined to another uprighted section. When a jacket is
complete and ready for launch, it is pulled along the skidway onto a launch
barge, which is gradually deballasted to compensate for the weight of the
structure as more of it moves aboard the barge. Using ocean-going tugs, the
barge and jacket are transported to the offshore installation site.
 
                                       2

  Decks are built either as single structures or in sections and are installed
on location by marine construction contractors. The composition and quantity
of petroleum in the well stream generally determine the makeup of the
production deck on a processing platform. Typical deck equipment includes
crude oil pumps, gas and oil separators and gas compressors. Unlike large
jackets, which are transported in a horizontal position, decks are transported
upright and, as a result, are not subject to the width restrictions of the
Houma Navigation Canal. Therefore, the only limitation on the Company's
ability to fabricate decks is the weight capacity of the barges that transport
the decks from the Company's yard, to the installation site. Barges currently
exist that have the weight capacity and other characteristics required to
transport even the largest of the decks currently installed in the Gulf of
Mexico, and management believes that currently there are no decks installed in
the Gulf of Mexico that could not have been constructed at the Company's
facilities. While larger deck structures to be built in the future could
exceed the capacities of currently existing barges, management does not
believe that this will materially affect its share of the market for deck
construction.
 
  The Company can also fabricate sections of, and structures used in
connection with, TLPs. TLPs consist of a deck that sits atop one or more
column-shaped hulls, which are positioned on site with vertical tendons
running from the hulls to the seabed. The tendons hold the hulls partially
submerged and are highly tensioned using the buoyancy of the hulls. This
system develops a restoring force against wave, wind and current actions in
proportion to the lateral displacement of the vessel. Wells for a TLP are
often pre-drilled through a subsea template. Long, flexible production risers,
which carry the petroleum to the deck of the TLP, are supported in tension by
mechanical tensioner machines on the platform's deck and are directly subject
to wave, wind and current forces. TLPs can be used in any water depth and are
generally better suited than fixed platforms for water depth greater than
1,000 feet.
 
  The size of a TLP depends on a number of factors, including the intended
scope of production of the platform, the length of the production risers
connected to the platform, the size of the deck to be installed on the
platform and the water depth for which the platform is designed. The Company
can fabricate deck sections for use with TLPs of any size. The constraints of
the Houma Navigation Canal, however, limit the Company's ability to deliver
certain hulls for use with TLPs, depending on the size and weight of the hull
sections. For example, the hulls that are used to support the TLPs currently
operating in the Gulf of Mexico were too large to transport through the Houma
Navigation Canal. All of these hull sections were fabricated by overseas
shipbuilding companies. The Company, however, is currently constructing the
deck section and floating hull of a TLP designed for installation in 1,700-
1,800 feet of water. The Company has also entered into a letter of intent to
construct a similar hull to be installed in 3,200 feet of water. To the
Company's knowledge, these are the first two TLPs of this size to be
constructed entirely in the United States. The Company should be able to
compete for further TLP projects of this size, including the fabrication of
hull sections.
 
  The Company has fabricated subsea templates for use in connection with TLPs,
which are structures that are installed on the seabed before development
drilling begins. As exploration and drilling move into the deep water of the
Gulf of Mexico, the Company believes that there will be increased
opportunities to fabricate subsea templates, as well as decks and other
structures, for use in connection with TLPs.
 
  The Company also fabricates piles and other rolled goods, templates, bridges
for connecting offshore platforms, wellhead protectors, various production,
compressor and utility modules and other structures used in offshore oil and
gas production and development activities. All of the Company's products are
installed by marine construction contractors.
 
  Through Dolphin Services, the Company also provides interconnect piping
services on offshore platforms, inshore steel and wood structure construction,
and steel warehousing and sales. Interconnect piping services involve sending
employee crews to offshore platforms that have been installed in the Gulf of
Mexico in order to perform welding and other activities required to connect
production equipment, service modules and other equipment to a platform prior
to its becoming operational. Dolphin Services also contracts with oil and gas
companies that have platforms and other structures located in the inland lakes
and bays throughout the Southeast
 
                                       3
<PAGE>
 
for various on-site construction and maintenance activities. At its existing
facility, a quarter of a mile from the Company's main yard, Dolphin Services
can fabricate jackets up to 100 feet tall along with decks and other steel
structures. Dolphin Services has also been active in the refurbishment of
existing platforms. Platform operators occasionally remove platforms
previously installed in the Gulf of Mexico and return the platforms to a
fabricator for refurbishment, which usually consists of general repairs,
maintenance work and modification.
 
FACILITIES AND EQUIPMENT
 
  Facilities. The Company's corporate headquarters and main fabrication yard
are located on the east bank of the Houma Navigation Canal at Houma,
Louisiana, approximately 30 miles from the Gulf of Mexico. That facility
includes approximately 140 acres with approximately 100 acres developed for
fabrication, one 13,200 square foot building that houses administrative staff,
approximately 180,000 square feet of covered fabrication area, and over 17,000
square feet of warehouse storage area and 8,000 square feet of training and
medical facilities. The main yard also has approximately 2,800 linear feet of
water frontage, of which 1,500 feet is steel bulkhead which permits outloading
of heavy structures.
 
  The Company's west yard is located across the Houma Navigation Canal from
the main yard and includes 437 acres, with 130 acres developed for fabrication
and over 300 acres of unimproved land, which could be used for expansion. The
west yard, which has approximately 72,000 square feet of covered fabrication
area and 3,500 square feet of warehouse storage area, spans 6,750 linear feet
of the Houma Navigation Canal, of which 2,350 feet is steel bulkhead.
 
  Dolphin Services operates from a 20-acre site located approximately a
quarter of a mile from the Company's main yard on a channel adjacent to the
Houma Navigation Canal. The facility includes a 7,000-square foot building
that houses administrative staff, approximately 14,000 square feet of covered
fabrication area, 1,500 square feet of warehouse storage area, a 10,000-square
foot blasting and coating facility and 600 linear feet of steel bulkhead.
 
  Southport is located on a 13-acre site located in Harvey, Louisiana, a
suburb of New Orleans, on the Harvey Canal, which has access to the Gulf of
Mexico through the Intracoastal Canal. The facility includes 7,550 square feet
of administrative offices, 22,300 square feet of covered fabrication area and
1,450 linear feet of steel bulkhead.
 
  The Company owns all of the foregoing properties except the property where
the Southport facility is located, which is held subject to a three-year
lease. The Company has an option to purchase this property that is exercisable
prior to May 14, 1999 at a purchase price of $1,150,000.
 
  Equipment. The Company's main yard houses its Bertsch Model 34 and Model 20
plate bending rolls, a Frye Wheelabrator grit blast system, a hydraulic plate
shear, a hydraulic press brake and various other equipment needed to build
offshore structures and fabricate steel components. The Company's west yard
has a Bertsch Model 38 plate bending roll, a computerized Vernon brace coping
machine used for cutting steel in complex geometric sections and various other
equipment used in the Company's fabrication business. The Company also
currently uses 19 crawler cranes, which range in tonnage capacity from 150 to
300 tons and service both of the Company's yards. The Company owns nine of
these cranes and rents the remaining 10 cranes on a monthly basis. The Company
recently purchased and installed a plasma-arc cutting system that cuts steel
up to one inch thick at a rate of two hundred inches per minute. The Company
performs routine repairs and maintenance on all of its equipment.
 
  The Company's plate bending rolls allow it to roll and weld into tubular
pipe sections approximately 50,000 tons of plate per year. By having such
capacity at its fabrication facility, the Company is able to coordinate all
aspects of platform construction, which can reduce the risk of cost overruns,
delays in project completion and labor costs. In addition, these facilities
often allow the Company to participate as subcontractors on projects awarded
to other contractors. The Company's grit blast system can blast steel at a
rate approximately ten times
 
                                       4
<PAGE>
 
faster than conventional sandblasting. This greatly reduces labor costs and
also decreases the Company's use of conventional sandblasting, which is
considered to be a more hazardous and slower method of preparing steel for
painting.
 
  For use in connection with its inshore construction activities, Dolphin
Services owns two spud barges. Dolphin Services also leases five barges for
use with inshore construction activities. Each barge is equipped with a crane
with a lifting capacity of 60 to 100 tons. Dolphin Services also owns two
Manitowoc 4100 cranes with lifting capacities of 200 to 230 tons and five
smaller cranes ranging from 60 to 100 tons lifting capacity. Southport rents
two crawler cranes with lifting capacities of 100 and 150 tons, respectively.
 
MATERIALS AND SUPPLIES
 
  The principal materials and supplies used by the Company in its fabrication
business, standard steel shapes, steel plate, welding gases, fuel oil,
gasoline and paint, are currently available in adequate supply from many
sources. The Company does not depend upon any single supplier or source.
 
SAFETY AND QUALITY ASSURANCE
 
  Management is concerned with the safety and health of the Company's
employees and maintains a stringent safety assurance program to reduce the
possibility of costly accidents. The Company's safety department establishes
guidelines to ensure compliance with all applicable state and federal safety
regulations and provides training and safety education through orientations
for new employees and subcontractors, weekly crew safety meetings and first
aid and CPR training. The Company also employs two in-house medical personnel.
The Company has a comprehensive drug program and conducts periodic employee
health screenings. A safety committee, whose members consist of management
representatives and peer-elected field representatives, meet monthly to
discuss safety concerns and suggestions that could prevent accidents. Through
1997 the Company rewarded its supervisory employees with safety bonuses based
on the amount that the Company saves under its self-insured workers'
compensation program compared to the existing rates of the Louisiana Worker's
Compensation Corporation.
 
  The Company fabricates to the standards of the American Petroleum Institute,
the American Welding Society, the American Society of Mechanical Engineers and
specific customer specifications. The Company uses welding and fabrication
procedures in accordance with the latest technology and industry requirements.
Training programs have been instituted to upgrade skilled personnel and
maintain high quality standards. In addition, the Company maintains on-site
facilities for the non-destructive testing of all welds, which process is
performed by an independent contractor.
 
  The Company's main and west yards are certified as an ISO 9002 fabricator.
ISO 9002 is an internationally recognized verification system for quality
management overseen by the International Standard Organization based in
Geneva, Switzerland. The certification is based on a review of the Company's
programs and procedures designed to maintain and enhance quality production
and is subject to annual review and recertification. Dolphin Services is
currently applying for ISO 9002 certification.
 
CUSTOMERS AND CONTRACTING
 
  The Company's customers are primarily major and independent oil and gas
companies. Over the past five years, sales of structures used in the Gulf of
Mexico by oil and gas companies accounted for approximately 77% of the
Company's revenue. The balance of its revenue was derived from the fabrication
of structures installed outside the Gulf of Mexico, including offshore West
Africa and Latin America.
 
  A large portion of the Company's revenue has historically been generated by
a few customers, although not necessarily the same customers from year-to-
year. For example, the Company's largest customers (those which individually
accounted for more than 10% of revenue in a given year) collectively accounted
for 67% (Texaco, Inc., British Petroleum Company and Atlantia Corporation),
35% (Shell Offshore, Inc., Global Industries
 
                                       5
<PAGE>
 
Offshore, Inc., Coastal Corporation) and 40% (Texaco, Inc., British Gas Ltd.)
of revenue for fiscal 1997, 1996 and 1995, respectively. In addition, at
December 31, 1997, 54% of the Company's backlog was attributable to three
projects, two of which were for the same customer. Because the level of
fabrication that the Company may provide to any particular customer depends,
among other things, on the size of that customer's capital expenditure budget
devoted to platform construction plans in a particular year and the Company's
ability to meet the customer's delivery schedule, customers that account for a
significant portion of revenue in one fiscal year may represent an immaterial
portion of revenue in subsequent years.
 
  Most of the Company's projects are awarded on a fixed-price or
alliance/partnering basis, and while customers may consider other factors,
including the availability, capability, reputation and safety record of a
contractor, price and the ability to meet a customer's delivery schedule are
the principal factors on which the Company is awarded contracts. The Company's
contracts generally vary in length from one month to eighteen months depending
on the size and complexity of the project. Generally, the Company's contracts
and projects are subject to termination at any time prior to completion at the
option of the customer. Upon termination, however, the customer is generally
required to pay the Company for work performed and materials purchased through
the date of termination and, in some instances, cancellation fees.
 
  Under fixed price contracts, the Company receives the price fixed in the
contract, subject to adjustment only for change orders approved by the
customer. As a result, the Company retains all cost savings but is also
responsible for all cost overruns. Under typical alliance/partnering
arrangements, the Company and the customer agree in advance to a target price
that includes specified levels of labor and material costs and profit margins.
If the project is completed at less cost than those targeted in the contract,
the contract price is reduced by a portion of the savings. If the cost of
completion is greater than those targeted in the contract, the contract price
is increased, but generally to the target price plus the actual incremental
cost of materials and direct labor costs. Accordingly, under
alliance/partnering arrangements, the Company has some protection from cost
overruns but also shares a portion of any cost savings with the customer.
Under cost-plus arrangements, the Company receives a specified fee in excess
of its direct labor and material cost and so is protected against cost
overruns but does not benefit directly from cost savings. Because the Company
generally prices materials as pass-through items on its contracts, the cost
and productivity of the Company's labor force are the primary factors
affecting the Company's operating costs. Consequently, it is essential that
the Company control the cost and productivity of the direct labor hours worked
on the Company's projects. As an aid to achieving this control, the Company
places a single project manager in charge of the production operations related
to each project and gives significant discretion to the project manager, with
oversight by the Company's Vice President of Operations. As an incentive to
control man-hours through 1997 the Company paid production bonuses to its
supervisory and salary employees if the actual hours worked on a contract are
less than the estimated hours used to formulate a bid for the project.
 
SEASONALITY
 
  Although high activity levels in the oil and gas industry and capacity
limitations have somewhat diminished the seasonality of the Company's
operations in recent years, the Company's operations have historically been
subject to seasonal variations in weather conditions and daylight hours. Since
most of the Company's construction activities take place outdoors, the number
of direct labor hours worked generally declines during the winter months due
to an increase in rainy and cold conditions and a decrease in daylight hours.
In addition, the Company's customers often schedule the completion of their
projects during the summer months in order to take advantage of the milder
weather during such months for the installation of their platforms. As a
result, a disproportionate portion of the Company's income has historically
been earned during the second and third quarters of the year, and the Company
has occasionally incurred losses during the first and fourth quarters of its
fiscal year. For example, the portion of net income earned during the second
and third quarters amounted to 57%, 61%, and 81% of the Company's total net
income for fiscal 1997, 1996 and 1995, respectively. Because of this
seasonality, full year results are not likely to be a direct multiple of any
particular quarter or combination of quarters.

COMPETITION
 
  The offshore platform fabrication industry is highly competitive and
influenced by events largely outside of the control of offshore platform
fabrication companies. Platform fabrication companies compete intensely for
available projects, which are generally awarded on a competitive bid basis
with customers usually requesting bids on projects one to three months prior
to commencement. The Company's marketing staff contacts oil and gas companies
believed to have fabrication projects scheduled to allow the Company an
opportunity to bid for the projects. Although price and the contractor's
ability to meet a customer's delivery schedule are the principal factors in
determining which qualified fabricator is awarded a contract for a project,
customers also consider, among other things, the availability of technically
capable personnel and facility space, a fabricator's efficiency, condition of
equipment, reputation, safety record and customer relations.
 
  The Company currently has two primary competitors, Aker Gulf Marine and J.
Ray McDermott, S.A., for the fabrication of platform jackets to be installed
in the Gulf of Mexico in water depths greater than 300 feet. In addition to
these two companies, the Company primarily competes with five other
fabricators for platform jackets for intermediate water depths from 150 feet
to 300 feet. A number of other companies compete for projects designed for
shallower waters as well as for the projects typically performed by Southport.
Certain of the Company's competitors have greater financial and other
resources than the Company.
 
  Management believes that, while new competitors can enter the market for
smaller structures relatively easily, it is more difficult for several reasons
to enter the market for jackets designed for use in water depths greater than
300 feet, including the substantial investment required to establish an
adequate facility, the difficulty of locating a facility adjacent to an
adequate waterway due to environmental and wetland regulations, and the
limited availability of experienced supervisory and management personnel.
 
  Management believes that the Company's competitive pricing, expertise in
fabricating offshore structures and its certification as an ISO 9002
fabricator will enable it to continue to compete effectively for projects
destined for international waters. The Company recognizes, however, that
foreign governments often use subsidies and incentives to create jobs where
oil and gas production is being developed. In addition, the additional
transportation costs that are incurred when exporting structures from the U.S.
to foreign locations may hinder the Company's ability to successfully bid for
projects against foreign competitors. Because of subsidies, import duties and
fees, taxes on foreign operators and lower wage rates in foreign countries
along with fluctuations in the value of the U.S. dollar and other factors, the
Company may not be able to remain competitive with foreign contractors for
projects designed for use in international waters as well as those designed
for use in the Gulf of Mexico.
 
BACKLOG
 
  As of December 31, 1997 the Company's backlog was $86.3 million, $79.7
million of which management expects to be performed during 1998. Of the $86.3
million backlog at December 31, 1997, approximately 54% was attributable to
three projects, two of which were for the same customer.
 
  The Company's backlog is based on management's estimate of the direct labor
hours required to complete, and the remaining revenue to be recognized with
respect to, those projects as to which a customer has authorized the Company
to begin work or purchase materials pursuant to written contracts, letters of
intent or other forms of authorization. Often, however, management's estimates
are based on incomplete engineering and design specifications. As engineering
and design plans are finalized or changes to existing plans are made,
management's estimate of the direct labor hours required to complete and price
at completion for such projects is likely to change. In addition, all projects
currently included in the Company's backlog are subject to termination at the
option of the customer, although the customer in that case is generally
required to pay the Company for work performed and materials purchased through
the date of termination and, in some instances, pay the Company cancellation
fees.

GOVERNMENT AND ENVIRONMENTAL REGULATION
 
  Many aspects of the Company's operations and properties are materially
affected by federal, state and local regulation, as well as certain
international conventions and private industry organizations. The exploration
and development of oil and gas properties located on the outer continental
shelf of the United States is regulated primarily by the Minerals Management
Service (United States Department of the Interior) ("MMS"). The MMS has
promulgated federal regulations under the Outer Continental Shelf Lands Act
requiring the construction of offshore platforms located on the outer
continental shelf to meet stringent engineering and construction
specifications. Violations of these regulations and related laws can result in
substantial civil and criminal penalties as well as injunctions curtailing
operations. The Company believes that its operations are in compliance with
these and all other regulations affecting the fabrication of platforms for
delivery to the outer continental shelf of the United States. In addition, the
Company depends on the demand for its services from the oil and gas industry
and, therefore, can be affected by changes in taxes, price controls and other
laws and regulations relating to the oil and gas industry. Offshore
construction and drilling in certain areas has also been opposed by
environmental groups and, in certain areas, has been restricted. To the extent
laws are enacted or other governmental actions are taken that prohibit or
restrict offshore construction and drilling or impose environmental protection
requirements that result in increased costs to the oil and gas industry in
general and the offshore construction industry in particular, the business and
prospects of the Company could be adversely affected, although such
restrictions in the areas of the Gulf of Mexico where the Company's products
are used have not been substantial. The Company cannot determine to what
extent future operations and earnings of the Company may be affected by new
legislation, new regulations or changes in existing regulations.
 
  The Houma Navigation Canal provides the only means of access for the
Company's products from the Company's facilities to open waters. The Houma
Navigation Canal is considered to be a navigable waterway of the United States
and, as such, is protected by federal law from unauthorized obstructions that
would hinder water-borne traffic. Federal law also authorizes federal
maintenance of the canal by the United States Corps of Engineers. The canal
requires annual dredging to maintain its water depth and, while federal
funding for this dredging has been provided for over 30 years, no assurance
that Congressional appropriations sufficient for adequate dredging and other
maintenance of the canal will be continued indefinitely. If sufficient funding
were not appropriated for that purpose, the Houma Navigation Canal could
become impassable by barges required to transport many of the Company's
products, with the result that the Company's operations and financial position
could be materially and adversely affected.
 
  The Company's operations and properties are subject to a wide variety of
increasingly complex and stringent foreign, federal, state and local
environmental laws and regulations, including those governing discharges into
the air and water, the handling and disposal of solid and hazardous wastes,
the remediation of soil and groundwater contaminated by hazardous substances
and the health and safety of employees. These laws may provide for "strict
liability" for damages to natural resources and threats to public health and
safety, rendering a party liable for the environmental damage without regard
to negligence or fault on the part of such party. Sanctions for noncompliance
may include revocation of permits, corrective action orders, administrative or
civil penalties and criminal prosecution. Certain environmental laws provide
for strict, joint and several liability for remediation of spills and other
releases of hazardous substances, as well as damage to natural resources. In
addition, the Company may be subject to claims alleging personal injury or
property damage as a result of alleged exposure to hazardous substances. Such
laws and regulations may also expose the Company to liability for the conduct
of or conditions caused by others, or for acts of the Company that were in
compliance with all applicable laws at the time such acts were performed.
 
  The Comprehensive Environmental Response, Compensation, and Liability Act of
1980, as amended, and similar laws provide for responses to and liability for
releases of hazardous substances into the environment. Additionally, the Clean
Air Act, the Clean Water Act, the Resource Conservation and Recovery Act, the
Safe Drinking Water Act, the Emergency Planning and Community Right to Know
Act, each as amended, and similar foreign, state or local counterparts to
these federal laws, regulate air emissions, water discharges, hazardous
substances and wastes, and require public disclosure related to the use of
various hazardous substances.
 
                                       8
<PAGE>
 
Compliance with such environmental laws and regulations may require the
acquisition of permits or other authorizations for certain activities and
compliance with various standards or procedural requirements. The Company
believes that its facilities are in substantial compliance with current
regulatory standards.
 
  The Company's operations are also governed by laws and regulations relating
to workplace safety and worker health, primarily the Occupational Safety and
Health Act and regulations promulgated thereunder. In addition, various other
governmental and quasi-governmental agencies require the Company to obtain
certain permits, licenses and certificates with respect to its operations. The
kind of permits, licenses and certificates required in the Company's
operations depend upon a number of factors. The Company believes that it has
all material permits, licenses and certificates necessary to the conduct of
its existing business.
 
  The Company's compliance with these laws and regulations has entailed
certain additional expenses and changes in operating procedures, which
historically have resulted in approximately $100,000 in expenditures per year.
The Company believes that compliance with these laws and regulations will not
have a material adverse effect on the Company's business or financial
condition for the foreseeable future. However, future events, such as changes
in existing laws and regulations or their interpretation, more vigorous
enforcement policies of regulatory agencies, or stricter or different
interpretations of existing laws and regulations, may require additional
expenditures by the Company, which expenditures may be material.
 
  Certain activities engaged in by employees of the Company, including
interconnect piping and other service activities conducted on offshore
platforms and activities performed on the spud barges owned by the Company,
are covered by the provisions of the Jones Act, the Death on the High Seas Act
and general maritime law, which laws operate to make the liability limits
established under state workers' compensation laws inapplicable to these
employees and, instead, permit them or their representatives to pursue actions
against the Company for damages or job related injuries, with generally no
limitations on the Company's potential liability. The Company's ownership and
operation of vessels can give rise to large and varied liability risks, such
as risks of collisions with other vessels or structures, sinkings, fires and
other marine casualties, which can result in significant claims for damages
against both the Company and third parties for, among other things, personal
injury, death, property damage, pollution and loss of business.
 
  In addition to government regulation, various private industry
organizations, such as the American Petroleum Institute, the American Society
of Mechanical Engineers and the American Welding Society, promulgate technical
standards that must be adhered to in the fabrication process.
 
INSURANCE
 
  The Company maintains insurance against property damage caused by fire,
flood, explosion and similar catastrophic events that may result in physical
damage or destruction to the Company's facilities. All policies are subject to
deductibles and other coverage limitations. The Company also maintains a
builder's risk policy for its construction projects and general liability
insurance. Gulf Island Fabrication, Inc. is self-insured for workers'
compensation liability except for losses in excess of $300,000 per occurrence
for Louisiana workers' compensation and for U.S. longshoreman and harbor
workers' coverage. Dolphin Services is conventionally insured for workers'
compensation liability with a $100,000 deductible. The Company also maintains
maritime employer's liability insurance. Although management believes that the
Company's insurance is adequate, 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
 
  The Company's workforce varies based on the level of ongoing fabrication
activity at any particular time. During 1997, the number of Company employees
ranged from approximately 525 to more than 1,000, approximately 335 of which
were added through the acquisition of Dolphin Services. As of March 1, 1998,
the
 
                                       9
<PAGE>
 
Company had approximately 1,250 employees, approximately 200 of which were
added through the acquisition of Southport. Although the seasonality of the
Company's operations may cause a decline in Company output during the winter
months, the Company generally does not lay off employees during those months
but reduces the number of hours worked per day by many employees to coincide
with the reduction in daylight hours during that period. None of the Company's
employees is employed pursuant to a collective bargaining agreement, and the
Company believes that its relationship with its employees is good.
 
  The Company's ability to remain productive and profitable depends
substantially on its ability to attract and retain skilled construction
workers, primarily welders, fitters and equipment operators. In addition, the
Company's ability to expand its operations depends primarily on its ability to
increase its labor force. The demand for such workers is high and the supply
is extremely limited. While the Company believes its relationship with its
skilled labor force is good, a significant increase in the wages paid by
competing employers could result in a reduction in the Company's skilled labor
force, increases in the wage rates paid by the Company, or both. If either of
these occurred, in the near-term, the profits expected by the Company from
work in progress could be reduced or eliminated and, in the long-term, to the
extent such wage increases could not be passed on to the Company's customers,
the production capacity of the Company could be diminished and the growth
potential of the Company could be impaired.
 
  As part of an effort to increase and improve its workforce, the Company
employs a full-time recruiter responsible for coordinating all aspects of the
Company's recruiting efforts, has instituted and enhanced several incentive
programs for its current employees and expanded its training facility. The
Company has facilities to train its employees on productivity and safety
matters. The Company is committed to training its employees and offers
advancement through in-house training programs.
 
CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING INFORMATION
 
  Certain statements included in this report and in oral statements made from
time to time by management of the Company that are not statements of
historical fact are forward-looking statements. In this report, forward-
looking statements are included primarily in the sections entitled "Business
and Properties," "Legal Proceedings," and "Management's Discussion and
Analysis of Financial Condition and Results of Operations." The words
"expect," "believe," "anticipate," "project," "plan," "estimate," "predict"
and similar expressions often identify forward-looking statements. All such
statements are subject to factors that could cause actual results and outcomes
to differ materially from the results and outcomes predicted in the statements
and investors are cautioned not to place undue reliance upon them.
 
ITEM 3. LEGAL PROCEEDINGS
 
  The Company is one of four defendants in a lawsuit (AGIP Petroleum Co. Inc.
v. Gulf Island Fabrication, Inc., McDermott Incorporated, Snamprogetti USA,
Inc. and Petro-Marine Engineering of Texas, Inc., Civil Action No. H-94-3382,
United States Federal District Court for the Southern District of Texas) in
which AGIP Petroleum Co. Inc. (the "Plaintiff") claims that the Company
improperly installed certain attachments to a jacket that it had fabricated
for the Plaintiff. The decision was made, without the Company's participation,
to remove the attachments prior to placing the jacket in its intended location
in the Gulf of Mexico and to modify the offshore installation plan. The
installation was unsuccessful and the jacket, after retrieval, required repair
and refurbishment. The Plaintiff, which has recovered most of its out-of-
pocket losses from its own insurer, seeks to recover the remainder of its
claimed out-of-pocket losses (approximately $1 million) and approximately $63
million for economic losses which it alleges resulted from the delay in oil
and gas production that was caused by these events and punitive damages. Co-
defendants with the Company include the installation contractor, the firm that
acted as the Plaintiff's agent in supervising the fabrication and installation
of the jacket and the design engineer that provided engineering services
related to the design and installation of the jacket. The Company has received
certain favorable rulings from the Court, particularly the Court's ruling that
the Company is not liable for economic losses with respect to certain of the
Plaintiff's principal causes of action; however, the Plaintiff could appeal
these rulings in the future. The Company believes that it has meritorious
defenses to the remaining
 
                                      10
<PAGE>
 
claims of the Plaintiff. In addition, the Company has asserted that it is
entitled to coverage as an additional named insured under the Plaintiff's
builders risk insurance policy relating to this project, although the insurer
is contesting coverage. The Company is vigorously contesting the Plaintiff's
claims. Based on the Company's analysis of the Plaintiff's claims, the
Company's defenses thereto and the Court's rulings received to date, the
Company believes that its liability for such claims, if any, will not be
material to its financial position. In view of the uncertainties inherent in
litigation, however, no assurance can be given as to the ultimate outcome of
such claims.
 
  The Company is a party to various other routine legal proceedings primarily
involving commercial claims, workers' compensation claims, and claims for
personal injury under the General Maritime Laws of the United States and the
Jones Act. While the outcome of these lawsuits, legal proceedings and claims
cannot be predicted with certainty, management believes that the outcome of
all such proceedings, even if determined adversely, would not have a material
adverse effect on the Company's business or financial condition.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS
 
  The Company's common stock, no par value per share (the "Common Stock"), is
traded on the Nasdaq National Market under the symbol "GIFI." At March 13,
1998, the Company had approximately 5,200 holders of its Common Stock of
record and individual participants including securities position listings.
 
  The following table sets forth the high and low bid prices per share of the
Common Stock, as reported by the Nasdaq National Market, for each fiscal
quarter since trading in the Common Stock began on April 4, 1997 (adjusted to
give retroactive effect for a two-for-one stock split of the Common Stock
effected in the form of a stock dividend paid on October 28, 1997).

  The Company currently intends to retain earnings, if any, to meet its
working capital requirements and to finance the future operation and growth of
its business and, therefore, does not plan to pay cash dividends to holders of
its Common Stock in the foreseeable future. Prior to the Initial Public
Offering, the Company made cash distributions to its shareholders in order to
provide a cash return to them as well as to fund their federal and state
income tax liability that resulted from the Company's prior status as an S
Corporation. These distributions totaled $2.7 million in the year ended
December 31, 1996, and $16.6 million through the termination of the Company's
S Corporation Status on April 4, 1997.

    $6.6 million attributable to portions of orders expected to be completed
    after December 31, 1998.
 
ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
 
GENERAL
 
  The Company's results of operations are affected primarily by (i) the level
of oil and gas exploration and development activity maintained by oil and gas
companies in the Gulf of Mexico, and to a lesser extent, West Africa and Latin
America; (ii) the Company's ability to win contracts through competitive
bidding or alliance/partnering arrangements and (iii) the Company's ability to
manage those contracts to successful completion. The level of exploration and
development activity is related to several factors, including trends of oil
and gas prices, exploration and production companies' expectations of future
oil and gas prices, and changes in technology which reduce costs and improve
expected returns on investment. Over the past five years, generally favorable
trends in these factors have led to increased activity levels in the Gulf of
Mexico.
 
  Improvements in three-dimensional seismic, directional drilling, production
techniques, and other advances in technology have increased drilling success
rates and reduced costs. Drilling activity has increased in and around
existing fields in shallow water (less than 300 feet) where technology has
allowed for the identification of smaller, previously overlooked oil and gas
deposits. Technological improvements have also led to larger discoveries of
oil and gas in subsalt geological formations (which generally are located in
300 to 800 feet of water) and in deep water (800 to 6,000 feet) areas of the
Gulf of Mexico. Increased activity in water depths greater than 300 feet,
where larger structures requiring more steel tonnage are needed, has placed
increased demand on the available capacity of the major platform fabricators
serving the Gulf of Mexico with a resulting improvement in pricing levels for
their services. Although the physical limitations of the Houma Navigation
Canal prevent the transporting of jackets for use in water depths greater than
800 feet, the increased activity in the deepwater areas of the Gulf of Mexico
has also benefitted the Company's pricing levels as the Company is able to
fabricate deck sections for installation on platforms used in any water depths
and sections of floating platforms, which are generally better suited than
fixed platforms for deepwater projects. In addition, to the extent the
Company's competitors are involved in deepwater projects, these projects
occupy a portion of the resources that the Company's competitors could apply
to projects designed for shallower waters, resulting in less industry capacity
for such projects.
 
                                      14
<PAGE>
 
  Demand for the Company's products and services is primarily a function of
the level of offshore oil and gas activity in the Gulf of Mexico and, to a
lesser extent, offshore areas in West Africa and Latin America. The Company
believes the number of blocks leased by oil and gas companies in the Gulf of
Mexico and the number of active drilling rigs in the Gulf of Mexico are
leading indicators of demand for the Company's products, with fabricating
activity trailing leasing and drilling activity by one to three years. Over
the past five years, improvements in seismic and drilling technology,
production techniques and oil and gas prices have resulted in an increased
number of acreage blocks leased, more intensive drilling activity in shallow
water areas, and increased exploration of deepwater areas of the Gulf of
Mexico. As a result, demand for the Company's products improved. Revenue in
1997 was $136.4 million, a 72.7% increase over 1996 revenue, and pro forma net
income was $12.2 million, a 180% increase over 1996 pro forma net income. The
Company's backlog at December 31, 1997 was $86.3 million as compared to $87.1
million at the end of 1996.
 
  Most of the Company's contracts are awarded on a fixed-price or
alliance/partnering basis although some contracts are bid on a cost-plus
basis. Under fixed-price contracts, the Company receives the price fixed in
the contract, subject to adjustment only for change orders placed by the
customer. As a result, the Company retains all cost savings but is also
responsible for all cost over-runs. Under typical alliance/partnering
arrangements, the Company and the customer agree in advance to a target price
that includes specified levels of labor and materials costs and profit
margins. If the project is completed at a lower cost than that targeted in the
contract, the contract price is reduced by a portion of the savings. If the
cost to completion is greater than target costs, the contract price is
increased, but generally to the target price plus the actual cost of
incremental materials and direct labor. Accordingly, under alliance/partnering
arrangements, the Company has some protection from cost overruns but also must
share a portion of any cost savings with the customer. Under cost-plus
arrangements, the Company receives a specified fee in excess of its direct
labor and materials cost and so is protected against cost overruns but does
not benefit directly from cost savings. Because the Company generally prices
materials as pass-through items on its contracts, the cost and productivity of
the Company's labor force are key factors affecting the Company's operating
profits. Consequently, it is essential that the Company control the cost and
productivity of the direct labor hours worked on the Company's projects.
 
  The ability of the Company to operate profitably and to expand its
operations depends substantially on its ability to attract skilled production
workers, primarily welders, fitters and equipment operators. As part of an
effort to increase and improve its workforce, the Company employs a full-time
recruiter responsible for coordinating all aspects of the Company's recruiting
efforts, has instituted and enhanced several recruitment incentive programs
for its current employees and expanded its training facility. While the supply
of production workers is limited, the demand for their services has increased
as oil and gas development and production activity has increased. As a result,
the Company has increased the average hourly wages of its employees and, in
some circumstances, has subcontracted work to others on a fixed-price basis
and, in 1994 and 1995, engaged contract labor. During 1997, the Company
increased its work force to approximately 1,000 employees, including
approximately 335 employees added through the acquisition of Dolphin Services.
The Company also added approximately 200 employees in January 1998 as a result
of its acquisition of Southport. Because the Company has succeeded in
increasing its production workforce through the acquisitions of Southport and
Dolphin Services and its own recruiting efforts, the Company does not
anticipate the need to engage a material amount of contract labor in the
foreseeable future.
 
  Although recent high activity levels in the oil and gas industry and
capacity limitations have somewhat diminished the seasonality of the Company's
operations in recent years, the Company's operations have traditionally been
subject to seasonal variations in weather conditions and daylight hours.
Because most of the Company's construction activities take place outdoors, the
number of direct labor hours worked generally declines during the winter
months due to an increase in rainy and cold conditions and a decrease in
daylight hours. In addition, the Company's customers often schedule the
completion of their projects during the summer months in order to take
advantage of the milder weather during such months for the installation of
their platforms. As a result, a disproportionate amount of the Company's net
income and, to a lesser extent, revenue and gross profit, has historically
been earned during the second and third quarters of the year, and the Company
 
                                      15
<PAGE>
 
has occasionally incurred losses during the first and fourth quarters of its
fiscal year. Because of this seasonality, full year results are not likely to
be a direct multiple of any particular quarter or combination of quarters. The
table below indicates for each quarter of the Company's last three fiscal
years the percentage of the annual revenue, gross profit and net income, and
the number of direct labor hours worked.

</TABLE>
 
  Most of the Company's revenue is recognized on a percentage-of-completion
basis based on the ratio of direct labor hours worked to the total estimated
direct labor hours required for completion. Accordingly, contract price and
cost estimates are reviewed monthly as the work progresses, and adjustments
proportionate to the percentage of completion are reflected in revenue for the
period when such estimates are revised. If these adjustments were to result in
a reduction of previously reported profits, the Company would have to
recognize a charge against current earnings, which may be significant
depending on the size of the project or the adjustment.
 
  The Company has developed a plan to modify its information technology to
recognize the year 2000. The Company has committed to purchase software and
upgrade its hardware to address the year 2000. The project is to be
substantially complete and operational by mid to late 1998 and is expected to
cost approximately $77,000. Management does not expect this project to have a
significant effect on the Company's operations. The Company is currently
evaluating its position with significant suppliers and large customers to
ensure that those parties have appropriate plans to address year 2000 issues
where they may otherwise impact the operations of the Company. The Company
does not have any significant suppliers or large customers that directly
interface with the Company's information technology systems. There is no
guarantee that the systems of the Company's suppliers and customers will be
year 2000 compliant and that such non-compliance will not have an adverse
effect on the Company.
 
RESULTS OF OPERATIONS
 
 Comparison of the Years Ended December 31, 1997 and 1996
 
  The Company's revenue for the year ended December 31, 1997 was $136.4
million, an increase of 72.7%, compared to $79.0 million in revenue for the
year ended December 31, 1996. Revenue increased as a result of the acquisition
of Dolphin Services and high activity levels in the oil and gas industry
during 1997 which created increased demand and, thus, upward pressure on the
pricing of the Company's goods and services. In addition, the on-going labor
recruiting and retention efforts at the Company generated an increase in the
volume of direct labor hours applied to contracts for the year ended December
31, 1997, compared to 1996 (2.1 million in 1997 versus 1.1 million in 1996).
The combination of increased volume and strong pricing enabled the Company to
increase gross profit by 135% to $24.3 million (17.8% of revenue) for the year
ended December 31, 1997, compared to the $10.3 million (13.1% of revenue) of
gross profit for the year ended December 31, 1996.
 
  Cost of revenue was $112.0 million in 1997 compared to $68.7 million in
1996. Cost of revenue consists of costs associated with the fabrication
process, including direct costs (such as direct labor hours and raw materials)
allocated to specific projects and indirect costs (such as supervisory labor,
utilities, welding supplies and equipment costs) that are associated with
production but are not directly related to a specific project. As a percentage
of revenue, these costs decreased to 82.2% compared to 86.9% in 1996.
 
  The Company's general and administrative expenses were $4.7 million for the
year ended December 31, 1997, compared to $2.7 million for the year ended
December 31, 1996. Although the absolute dollar cost of the Company's general
and administrative expenses increased by $2.0 million for 1997, as a
percentage of revenue,
 
                                      16
<PAGE>
 
it remained constant at 3.4%. The increase of $2.0 million for the year was
caused by (i) additional general and administrative costs associated with
Dolphin Services, (ii) greater accrual of performance-based employee
incentives which resulted from increased profits for the year ended December
31, 1997, and (iii) additional costs associated with increased production
levels and the reporting requirements of a public company for 1997.
 
  The Company's net interest expense decreased to $100,000 for 1997 compared
to $400,000 for 1996. As a result of the use of the net proceeds from the
Company's Initial Public Offering to repay all of the Company's outstanding
debt and net cash provided by operations of $18.3 million in 1997, as compared
to $7.2 million in 1996, the weighted average borrowings for 1997 were lower
in comparison to 1996.
 
  The Company converted to C Corporation status on April 4, 1997. Pro forma
provision for income taxes and pro forma net income give effect to federal and
state income taxes as if all entities presented had been taxed as C
Corporations during all the periods presented of both 1996 and 1997. Pro forma
net income excludes a non-recurring charge of $1.1 million to record the
cumulative deferred income tax provision upon the election on April 4, 1997 to
convert from S Corporation status to C Corporation status.
 
 Comparison of the Years Ended December 31, 1996 and 1995
 
  During the year ended December 31, 1996, the Company generated revenue of
$79.0 million, an increase of 23.8% compared to the $63.8 million generated in
1995. This increase was caused by a 16.6% increase in production volume (1.1
million direct labor hours worked in 1996 versus 0.9 million in 1995) and an
increase of 6.2% in the Company's average selling rate. The Company's average
selling rate is computed by dividing revenue for any period by the number of
direct labor hours worked in such period. As a result of stronger demand for
fabricated structures in the oil and gas industry, the Company was able to
increase the number of direct labor hours worked by hiring additional
employees and increase its average selling rate by raising the prices charged
to its customers. The 6.2% increase in average selling rate is not fully
indicative of the prices charged by the Company on all of its projects since
it includes work performed and projects completed in the early part of 1996
for contracts awarded during 1995 as well as work performed and projects
completed in late 1996 for projects awarded during the improving market
conditions of early 1996.
 
  Cost of revenue was $68.7 million in 1996 compared to $60.0 million in 1995.
These costs decreased to 89.9% of revenue in 1996 from 94.1% of revenue in
1995, primarily as a result of the increase in pricing discussed above and a
decrease in the cost of revenue that resulted primarily from (i) productivity
increases caused by labor saving equipment and production incentives, (ii) a
reduction in equipment rental costs which was partially offset by increased
depreciation expense which resulted from equipment purchases and (iii) an
increase in the amount of scrap steel sold.
 
  Excluding a $500,000 non-recurring compensation expense in 1996, general and
administrative expenses were $2.2 million in 1996 compared to $1.7 million in
1995, remaining a constant 2.7% of revenue for each period.
 
  Interest expense decreased to $384,000 in 1996 from $430,000 in 1995 as the
weighted average of the Company's borrowings decreased during 1996.
 
PRO FORMA TAX ADJUSTMENTS
 
  From April 1989 until April 4, 1997, the Company operated as an S
Corporation for federal and state income tax purposes. As a result, the
Company paid no federal or state income tax, and the entire earnings of the
Company were subject to tax directly at the shareholder level. Immediately
prior to the Initial Public Offering, the Company's shareholders elected to
terminate the Company's S Corporation status. As a result, the Company
recorded a one-time deferred tax liability in the amount of approximately $1.1
million in the second quarter of 1997. Pro forma income taxes related to
operations as an S Corporation for 1997 and 1996 would have been $1.4 million
and $2.9 million, respectively.
 
                                      17
<PAGE>
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company completed the Initial Public Offering on April 9, 1997 in which
it sold 4.6 million shares of Common Stock and received net proceeds of $31.3
million after underwriting discounts and other costs of $3.2 million. Of the
net proceeds, the Company used $31.1 million to repay all of the indebtedness
outstanding under the Company's Bank Credit Facility (as defined herein). The
balance of the proceeds was used by the Company as additional working capital.
Working capital increased 60% from the prior year end to $17.6 million at
December 31, 1997.
 
  Historically the Company has funded its business activities through funds
generated from operations and borrowings under its Bank Credit Facility. Net
cash provided by operations increased by 156% to $18.3 million for the year
ended December 31, 1997, primarily attributable to cash received from
customers related to increased sales. Net cash used in investing activities
for the year ended December 31, 1997 was $20.7 million, related to the $5.8
million purchase of Dolphin Services, $15.2 million of capital expenditures
and $300,000 of other miscellaneous items. The Company's capital expenditures
were for improvements to its production facilities and for equipment designed
to increase the capacity of its facilities and the productivity of its labor
force. During 1997 the Company purchased five new Manitowoc cranes and a used
American Model 5300 crane, constructed a pressure vessel fabrication facility,
expanded its fabrication shop and pipe mill, installed construction skidways,
and acquired various other fabrication equipment and facilities.
 
  Net cash provided by financing activities of $7.9 million during 1997
represented the net proceeds of $31.3 million from the Initial Public Offering
offset by $16.6 million of dividends paid to shareholders in connection with
the termination of the Company's S Corporation status prior to the Initial
Public Offering and $6.8 million net payments of notes payable under the Bank
Credit Facility.
 
  The Company's bank credit facility (the "Bank Credit Facility") currently
provides for a revolving line of credit of up to $20.0 million which bears
interest equal to, at the Company's option, the prime lending rate established
by Citibank, N.A. or LIBOR plus 1 1/2%. The Bank Credit Facility matures
December 31, 1999 and is secured by a mortgage on the Company's real estate,
equipment and fixtures, and by the stock of Dolphin Services. As additional
security, the Company has caused Dolphin Services to guarantee the Company's
obligations under the Bank Credit Facility. At December 31, 1997, there were
no borrowings outstanding under the Bank Credit Facility.
 
  Effective January 1, 1998, the Company acquired all the outstanding stock of
Southport. The purchase price was $6.0 million in cash, plus contingent
payments of up to $5.0 million based on Southport's net income over a four
year period ending December 31, 2001. The initial payment of $6.0 million was
funded through working capital generated from operations.
 
  The Company's Board of Directors has approved a capital budget of $14.6
million for 1998, including the purchase of five Manitowoc 888 crawler cranes,
an additional skidway system for large jackets, automated painting, welding
and steel cutting systems and another barge, equipped with an 80-ton crane,
for use in inland construction operations. Management believes that its
available funds, cash generated by operating activities and funds available
under the Bank Credit Facility will be sufficient to fund these capital
expenditures and its working capital needs. However, the Company may expand
its operations through acquisitions in the future, which may require
additional equity or debt financing.

                        REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders
Gulf Island Fabrication, Inc.
 
  We have audited the accompanying consolidated balance sheet of Gulf Island
Fabrication, Inc. as of December 31, 1997 and the related consolidated
statements of income, shareholders' equity, and cash flows for the year then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audit. The consolidated financial statements of Gulf
Island Fabrication, Inc. as of December 31, 1996, and for each of the two
years in the period ended December 31, 1996, were audited by other auditors
whose report dated January 23, 1997, except for the third paragraph of Note 1
which is as of February 13, 1997, the second paragraph of Note 4 which is as
of February 14, 1997, and the third paragraph of Note 4 which is as of October
28, 1997, expressed an unqualified opinion on those statements.
 
  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.
 
  In our opinion, the 1997 financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Gulf
Island Fabrication, Inc. at December 31, 1997, and the consolidated results of
its operations and its cash flows for the year then ended in conformity with
generally accepted accounting principles.

                         GULF ISLAND FABRICATION, INC.
 
                NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
 
                  FOR THE THREE YEARS ENDED DECEMBER 31, 1997
 
NOTE 1--ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Basis of Presentation
 
  Gulf Island Fabrication, Inc. ("Gulf Island"), located in Houma, Louisiana,
is engaged in the fabrication and refurbishment of offshore oil and gas
platforms for oil and gas industry companies. Gulf Islands principal markets
are concentrated in the offshore regions of the coast of the Gulf of Mexico.
The consolidated financial statements include the accounts of Gulf Island and
its wholly owned subsidiary (collectively "the Company"). All significant
intercompany balances and transactions have been eliminated in consolidation.
 
  On January 2, 1997, Gulf Island acquired all outstanding shares of Dolphin
Services, Inc., Dolphin Steel Sales, Inc. and Dolphin Sales and Rentals Inc.
for $5.9 million (the "Dolphin Acquisition"). The acquired corporations
perform fabrication, sandblasting, painting and construction services for
offshore oil and gas platforms in inland and offshore regions of the coast of
the Gulf of Mexico. On April 30, 1997, Dolphin Steel Sales, Inc. and Dolphin
Sales and Rentals, Inc. merged into Dolphin Services, Inc. The three
corporations are referred to hereinafter collectively as "Dolphin Services."
The Dolphin Acquisition was financed by borrowings under Gulf Island's line of
credit. Gulf Island acquired assets with a fair value of $9.7 million and
assumed liabilities of $3.8 million. The acquisition was accounted for under
the purchase method of accounting. Accordingly, the operations of Dolphin
Services are included in the Company's operations from January 2, 1997.
 
  On February 13, 1997, the Board of Directors approved the filing of an
initial registration statement on Form S-1 with the Securities and Exchange
Commission to register and sell 4.6 million shares of common stock. Shortly
before closing of the offering on April 9, 1997, the Company's current
shareholders elected to terminate its status as an S Corporation, and the
Company became subject to federal and state income taxes. (See Note 2.)
 
  On April 3, 1997, the Securities and Exchange Commission declared the
Company's Registration Statement on Form S-1 (Registration No. 333-21863)
effective. On April 9, 1997, the Company sold 4.6 million common shares
pursuant to the registration statement, increasing the total shares
outstanding to 11.6 million (the "Initial Public Offering"). The Company
received $34.5 million from the sale of the shares and paid $3.2 million for
underwriting and other fees related to the Initial Public Offering resulting
in net proceeds from the sale of $31.3 million.
 
 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 liabilities at the date of the financial statements
and the reported amounts of revenue and expense during the reporting period.
Actual results could differ from those estimates.
 
 Concentration of Credit Risk
 
  The principal customers of the Company are the major and large independent
oil and gas companies. These concentrations of customers may impact the
Company's overall exposure to credit risk, either positively or negatively, in
that customers may be similarly affected by changes in economic or other
conditions. However, the Company's management believes that the portfolio of
receivables is diversified and that such diversification minimizes any
potential credit risk. Receivables are generally not collateralized.
 
  The Company believes that its provision for possible losses on uncollectible
accounts receivable is adequate for its credit loss exposure.

                         GULF ISLAND FABRICATION, INC.
 
          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 Inventory
 
  Inventory consists of materials and production supplies and is stated at the
lower of cost or market determined on the first-in, first-out basis.
 
 Property, Plant and Equipment
 
  Property, plant and equipment is stated at cost less accumulated
depreciation. Depreciation is computed on the straight-line basis over the
estimated useful lives of the assets, which range from 3 to 25 years. Ordinary
maintenance and repairs, which do not extend the physical or economic lives of
the plant or equipment, are charged to expense as incurred.
 
 Revenue Recognition
 
  Revenue from fixed-price and cost-plus construction contracts is recognized
on the percentage-of-completion method, computed by the efforts-expended
method which measures the percentage of labor hours incurred to date as
compared to estimated total labor hours for each contract.
 
Contract costs include all direct material, labor and subcontract costs and
those indirect costs related to contract performance, such as indirect labor,
supplies and tools. Also included in contract costs are a portion of those
indirect contract costs related to plant capacity, such as depreciation,
insurance and repairs and maintenance. These indirect costs are allocated to
jobs based on actual direct labor hours incurred. Profit incentives are
included in revenue when their realization is reasonably assured. Claims for
extra work or changes in scope of work are included in revenue when collection
is probable. Provisions for estimated losses on uncompleted contracts are made
in the period in which such losses are determined
 
  The asset caption entitled "costs and estimated earnings in excess of
billings on uncompleted contracts," represents revenue recognized in excess of
the amounts billed. The liability caption entitled "billings in excess of
costs and estimated earnings on uncompleted contracts" represents billings in
excess of revenue recognized.
 
 Income Taxes
 
  Income taxes have been provided using the liability method in accordance
with the Financial Accounting Standards Board's Statement No. 109, "Accounting
for Income Taxes." Prior to April 4, 1997, the Company's shareholders had
elected to have the Company taxed as an S Corporation for federal and state
income tax purposes whereby shareholders were liable for individual federal
and state income taxes on their allocated portions of the Company's taxable
income. Accordingly, the historical financial statements do not include any
provision for income taxes during the period the Company was an S Corporation
(see Note 2).
 
 Reclassifications
 
  Certain items included in the financial statements for the years ended
December 31, 1996 and 1995 have been reclassified to conform to the December
31, 1997 financial statement presentation.
 
NOTE 2--TERMINATION OF S CORPORATION STATUS
 
  On April 4, 1997, the Company's shareholders elected to terminate the
Company's status as an S Corporation, and the Company became subject to
federal and state income taxes. In conjunction with the termination of S
Corporation status, the Company paid a distribution of $14 million to its
current shareholders representing substantially all of the Company's remaining
undistributed S Corporation earnings through April 4, 1997. The S Corporation
earnings for the period April 1, 1997 to April 4, 1997 were an immaterial part
of the

total distribution. The balance sheet of the Company as of December 31, 1997
reflects a deferred income tax liability of $1.9 million, which includes $1.1
million of deferred income tax liability resulting from the termination of the
S Corporation status. The amount of the Company's retained earnings represents
primarily the C Corporation earnings prior to the Company's election of S
Corporation status in 1989 and earnings after April 4, 1997.
 
  The pro forma income statement presentation reflects an additional provision
for income taxes as if the Company had been subject to federal and state
income taxes since January 1, 1995 using an assumed effective tax rate of
approximately 38%.
 
NOTE 3--ACQUISITION OF DOLPHIN SERVICES
 
  The following unaudited pro forma information presents a summary of
consolidated results of operations of Gulf Island and Dolphin Services as if
the acquisition had occurred on January 1, 1996. Pro forma adjustments include
(1) elimination of intercompany sales between Gulf Island and Dolphin
Services, (2) adjustments for the increase in interest expense on acquisition
debt, (3) additional depreciation on property, plant and equipment, and (4)
related tax effects. The effects of termination of the S corporation status
(Note 2) are excluded.

NOTE 4--SHAREHOLDERS' EQUITY
 
  On December 1, 1996, Gulf Island's principal shareholders sold 98,000 (1.4%)
of their existing shares to officers and management employees at $3.57 per
share (number of shares and per share prices adjusted for effect of stock
splits described in following paragraphs). The per share price on that date
was based on an independent appraisal that valued Gulf Island as a privately
held business. As a result of the Initial Public Offering, the Company
determined that it should record a non-recurring, non-cash compensation charge
of $500,000 for the year ended December 31, 1996 related to the 98,000 shares.
This charge was based on the difference between the net offering price the
Company expected to receive in the public offering and the net cash price
recipients of the 98,000 shares expected to pay. The net cash price to
recipients of $1.78 per share represented the $3.57 per share price charged by
the shareholders, less $1.88 per share of tax-free dividends that the
recipients expected to receive as a result of the shareholder distributions
described in Note 2, increased by the recipient's share of taxable income for
the year of $.09 per share (in each case adjusted for the effect of the stock
splits described in the following paragraphs). The compensation charge
resulted in a corresponding increase to additional paid-in capital.
 
  On February 14, 1997, the shareholders enacted the following:
 
    (a) Authorized the issuance of 2.5 shares of no par value common stock
  for each of the then outstanding 2,000,000 shares, which resulted in
  7,000,000 total outstanding shares. This recapitalization is reflected
  retroactively in the accompanying financial statements and per share
  calculations.
 
    (b) Authorized 5,000,000 shares of no par value preferred stock. There
  are no preferred shares issued or outstanding.
 
    (c) Increased the authorized common shares from 10,000,000 shares to
  20,000,000 shares.

                         GULF ISLAND FABRICATION, INC.
 
          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  On October 6, 1997, the Company's Board of Directors authorized a two-for-
one stock split effected in the form of a stock dividend that became effective
on October 28, 1997 to shareholders of record on October 21, 1997. All share
and per share data included in the financial statements have been restated to
reflect the stock split.
 
NOTE 5-- PRO FORMA PER SHARE DATA
 
  Pro forma per share data as shown in the statement of income consists of the
Company's historical income, adjusted to reflect income taxes as if the
Company had operated as a C Corporation during all periods presented. This
calculation for the year ended December 31, 1997 excludes the charge of $1.1
million related to cumulative deferred income taxes resulting from conversion
to a C Corporation on April 4, 1997. Further, the weighted average share
calculations for 1997 include the assumed issuance of additional shares
sufficient to pay the distributions made to shareholders in connection with
the Company's Initial Public Offering, to the extent such distributions
exceeded net income for the year ended December 31, 1996.
 
NOTE 6--NEW ACCOUNTING STANDARD
 
  In 1997, the Financial Accounting Standards Board issued Statement No. 128,
"Earnings per Share." Statement No. 128 replaced APB Opinion No. 15 for the
calculation of primary and fully diluted earnings per share with basic and
diluted earnings per share. Unlike primary earnings per share, basic earnings
per share exclude any dilutive effects of options, warrants and convertible
securities. Diluted earnings per share is very similar to the previously
reported fully diluted earnings per share. All earnings per share amounts for
all periods have been presented, and where appropriate, restated to conform to
the Statement No. 128 requirements.
 
  The following table sets forth the computation of basic and diluted earnings
per share (in thousands, except per share data):

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The Company leases certain equipment used in the normal course of its
operations under month-to-month lease agreements cancelable only by the
Company. During 1997, 1996, and 1995, the Company expensed $3,203,000,
$2,801,000, and $3,000,000, respectively, related to these leases.
 
NOTE 11--INCOME TAXES
 
  On April 4, 1997, the Company's shareholders elected to terminate the
Company's status as an S Corporation, and the Company became subject to
federal and state income taxes (see Note 2). In conjunction with the Company's
change in tax status, the Company recorded a $1.1 million deferred tax
liability.
 
  Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components
of the Company's deferred tax assets and liabilities as of December 31, 1997
are as follows (in thousands):

NOTE 12--LINE OF CREDIT AND NOTES PAYABLE
 
  The Company's bank credit facility provides for a revolving line of credit
(the "Revolver") of up to $20.0 million which bears interest equal to, at the
Company's option, the prime lending rate established by Citibank, N.A. or
LIBOR plus 1.5%. The Revolver matures December 31, 1999 and is secured by a
mortgage on the Company's real estate, equipment and fixtures, and the stock
of Dolphin Services. At December 31, 1997, there were no borrowings
outstanding under the credit facility. The Company is required to maintain
certain balance sheet and cash flow ratios. The Company pays a fee quarterly
of three-eighths of one percent per annum on the average unused portion of the
line of credit.

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  During 1997, the Company used a portion of the net proceeds received from
the Initial Public Offering (see Note 1) to repay all of its indebtedness.
 
NOTE 13--LONG-TERM INCENTIVE PLAN
 
  The Company has elected to follow Accounting Principles Board Opinion No. 25
"Accounting for Stock Issued to Employees" (APB 25) and related
interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FASB
Statement No. 123, "Accounting For Stock-Based Compensation" (Statement 123),
requires use of option valuation models that were not developed for use in
valuing employee stock options. Under APB 25, because the exercise price of
the Company's employee stock options equal the market price of the underlying
stock on the date of grant, no compensation expense is recognized.
 
  On February 13, 1997, the Board of Directors adopted the Long-Term Incentive
Plan (the "Plan"). The Plan has authorized the grant of options to purchase an
aggregate of 1,000,000 shares of the Company's common stock to certain
officers and key employees of the Company chosen by a committee appointed by
the Board of Directors (the "Compensation Committee") to administer such plan.
Under the Plan, all options granted have 10-year terms, and conditions
relating to the vesting and exercise of options are determined by the
Compensation Committee for each option. Options granted under the Plan are
"non-statutory options" (options which do not afford income tax benefits to
recipients, but the exercise of which may provide tax deductions for the
Company). Each option will have an exercise price per share not less than the
fair market value of a share of common stock on the date of grant and no
individual employee may be granted options to purchase more than an aggregate
of 400,000 shares of common stock. These options vest over a five-year period.
 
  Pro forma information regarding net income and earnings per share is
required by Statement 123 and has been determined as if the Company had
accounted for its employee stock options under the fair value method of that
statement. The fair value for these options was estimated at the date of grant
using the Black-Sholes option pricing model with the following weighted
average assumptions for 1997: a risk-free interest rate of 6.36%; dividend
yield of zero; volatility factor of the expected market price of the Company's
common stock of .745; and a weighted average expected life of the options of
eight years.
 
  The Black-Scholes option valuation model was developed for use in estimating
the fair value of trade options, which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in
the subjective input assumptions can materially affect the fair value
estimated, in management's option, the existing models do not necessarily
provide a reliable single measure of the fair value of its employee stock
options.

  For purposes of pro forma disclosures, the estimated fair value of the
options (net of expected tax benefits) is amortized to expense over the
options' vested period. Since the Company's options generally vest over a
five- year period, the pro forma disclosures are not indicative of future
amounts until Statement 123 is applied to all outstanding non-vested options.

that it had fabricated for the plaintiff. The plaintiff, which has recovered
most of its out-of-pocket losses from its own insurer, seeks to recover the
remainder of its claimed out-of-pocket losses (approximately $1 million) and
approximately $63 million for punitive damages and for economic losses which
it alleges resulted from the delay in oil and gas production that was caused

                         GULF ISLAND FABRICATION, INC.
                       (AS AMENDED ON FEBRUARY 4, 1998)


                                   SECTION 1

                                    OFFICES

     1.1  PRINCIPAL OFFICE.  The principal office of the Corporation shall be
located at 583 Thompson Road, Houma, Louisiana 70363.

     1.2  ADDITIONAL OFFICES.  The Corporation may have such offices at such
other places as the Board of Directors may from time to time determine or the
business of the Corporation may require.

                                   SECTION 2

                              SHAREHOLDER MEETINGS

     2.1  PLACE OF MEETINGS.  Unless otherwise required by law or these By-laws,
all meetings of the shareholders shall be held at the principal office of the
Corporation or at such other place, within or without the State of Louisiana, as
may be designated by the board of Directors.

     2.2  ANNUAL MEETINGS; NOTICE THEREOF.  An annual meeting of the
shareholders shall be held each year on the date and at the time as the Board of
Directors shall designate, for the purpose of electing directors and of the
transaction of such other business as may be properly brought before the
meeting.  If no annual shareholders' meeting is held for a period of eighteen
months, any shareholder may call such meeting to be held at the registered
office of the Corporation as shown on the records of the Secretary of State of
the State of Louisiana.

     2.3  SPECIAL MEETINGS.  Special meetings of the shareholders, for any
purpose or purposes, may be called by or at the direction of the Board of
Directors.  Shareholders may call a special meeting of shareholders in
accordance with the applicable provisions of the Articles of Incorporation.

     2.4  NOTICE OF MEETINGS.  Except as otherwise provided by law or the
Articles of Incorporation, the authorized person or persons calling a
shareholders' meeting shall cause written notice of the time, place and purpose
of the meeting to be given to all shareholders entitled to vote at such meeting,
at least 10 days and not more than 75 days prior to the day fixed for the
meeting. Notice of the annual meeting need not state the purpose or purposes
thereof, unless action is to be 
<PAGE>
 
taken at the meeting as to which notice is required by law or the By-laws.
Notice of a special meeting shall state the purpose or purposes thereof, and the
business conducted at any special meeting shall be limited to the purpose or
purposes stated in the notice.

     2.5  LIST OF SHAREHOLDERS.  At every meeting of shareholders, a list of
shareholders entitled to vote, arranged alphabetically and certified by the
Secretary or by the agent of the Corporation having charge of transfers of
shares, showing the number and class of shares held by each such shareholder on
the record date for the meeting and confirming the number of votes per share as
to which each such shareholder is entitled, shall be produced on the request of
any shareholder.

     2.6  QUORUM.  At all meetings of shareholders, the holders of a majority of
the total voting power shall constitute a quorum; provided, however, that this
subsection shall not have the effect of reducing the vote required to approve
any matter that may be established by law, the Articles of Incorporation or
these By-laws.

     2.7  VOTING.  When a quorum is present at any shareholders' meeting, the
vote of the holders of a majority of the votes actually cast shall decide each
question brought before such meeting, unless the resolution of the question
requires, by express provision of law, the Articles of Incorporation or these
By-laws, a different vote or one or more separate votes by the holders of a
class or series of capital stock, in which case such express provision shall
apply and control the decision of such question.  Directors shall be elected by
plurality vote.

     2.8  PROXIES.  At any meeting of the shareholders, every shareholder having
the right to vote shall be entitled to vote in person or by proxy appointed by
an instrument in writing executed by such shareholder and bearing a date not
more than eleven months prior to the meeting, unless the instrument provides for
a longer period, but in no case will an outstanding proxy be valid for longer
than three years from the date of its execution.  The person appointed as proxy
need not be a shareholder of the Corporation.

     2.9  ADJOURNMENTS.  Adjournments of any annual or special meeting of
shareholders may be taken without new notice being given unless a new record
date is fixed for the adjourned meeting, but any meeting at which directors are
to be elected shall be adjourned only from day to day until such directors shall
have been elected.

     2.10 WITHDRAWAL. If a quorum is present or represented at a duly organized
shareholders' meeting, such meeting may continue to do business until
adjournment, notwithstanding the withdrawal of enough shareholders to leave less
than a quorum as fixed in Section 2.6 of these By-laws, or the refusal of any
shareholders to vote.

     2.11 LACK OF QUORUM. If a meeting cannot be organized because a quorum has
not attended, those present may adjourn the meeting to such time and place as
they may determine, subject, however, to the provisions of Section 2.9 hereof.
In the case of any meeting called for the 

                                      -2-
<PAGE>
 
election of directors, those who attend the second of such adjourned meetings,
although less than a quorum as fixed in Section 2.6 hereof, shall nevertheless
be deemed to constitute a quorum for the purpose of electing directors.

     2.12  PRESIDING OFFICER.  The Chairman of the Board or a person designated
by the Chairman of the Board, or in their absence a person designated by the
Board of Directors, shall preside at all shareholders' meetings.

     2.13  DEFINITION OF SHAREHOLDER.  As used in these By-laws, and unless the
context otherwise requires, the term shareholder shall mean a person who is (i)
the record holder of shares of the Corporation's common stock or any other
capital stock of the Corporation granted voting rights, or (ii) a registered
holder of any bonds, debentures or similar obligations granted voting rights by
the Corporation pursuant to La.R.S. 12:75H.


                                   SECTION 3

                                   DIRECTORS

     3.1  NUMBER.  All of the corporate powers shall be vested in, and the
business and affairs of the Corporation shall be managed by, a Board of
Directors.  Except as otherwise fixed by or pursuant to Article III(B) of the
Articles of Incorporation (as it may be duly amended from time to time) relating
to the rights of the holders of any class or series of stock having a preference
over the Common Stock as to dividends or upon liquidation to elect additional
directors by class vote, the Board of Directors shall consist of eight natural
persons; provided that, if after the last action of the Board of Directors with
respect to nomination of directors prior to the mailing to shareholder of proxy
materials for any meeting of shareholders at which directors are to be elected,
any person or persons named therein to be nominated at the direction of the
Board of Directors becomes unable or unwilling to serve, the foregoing number of
authorized directors shall be automatically reduced by a number equal to the
number of such persons unless the Board of Directors selects a replacement
nominee or nominees.  No director need be a shareholder.  The Secretary shall
have the power to certify at any time as to the number of directors authorized
and as to the class to which each director has been elected or assigned.

     3.2  POWERS.  The Board may exercise all such powers of the Corporation and
do all such lawful acts and things which are not by law, the Articles of
Incorporation or these By-laws directed or required to be done by the
shareholders.

     3.3  CLASSES.  The Board of Directors, other than those directors who may
be elected by the holders of any class or series of stock having preference over
the Common Stock as to dividends or upon liquidation (whose term of office may
be determined by the Board of Directors pursuant to Section 3.3), shall be
divided, with respect to the time during which they shall hold office, into
three classes as nearly equal in number as possible, with the initial term of
office of Class I directors expiring at the annual meeting of shareholders to be
held in 1998, of Class II Directors expiring at 

                                      -3-
<PAGE>
 
the next succeeding annual meeting of shareholders and of Class III directors
expiring at the second succeeding annual meeting of shareholders, with all such
directors to hold office until their successors are elected and qualified. At
each annual meeting of shareholders, directors chosen to succeed those whose
terms then expire shall be elected to hold office for a term expiring at the
annual meeting of shareholder held in the third year following the year of their
election and until their successors are duly elected and qualified. If the Board
of Directors shall appoint any director to fill a vacancy on the Board, whether
resulting from an increase in the number of directors or otherwise, such
Director shall be assigned to a class by the Board of Directors so that all
classes of directors shall be as nearly equal in number as possible. In the
event of a decrease in the number of directors, the Board of Directors may
reassign the remaining directors to classes so that all classes of directors
shall be as nearly equal in number as possible.

     3.4  GENERAL ELECTION.  At each annual meeting of shareholders, directors
shall be elected to succeed those directors whose terms then expire.  No
decrease in the number of directors constituting the Board of Directors shall
shorten the term of any incumbent director.

     3.5  VACANCIES.  Except as otherwise provided in the Articles of
Incorporation or these By-laws, the office of a director shall become vacant if
he dies, resigns or is duly removed from office.

     3.6  FILLING VACANCIES.  Except as otherwise provided in the Articles of
Incorporation or Section 3.8 of these By-laws, any vacancy on the board
(including any vacancy resulting from an increase in the authorized number of
directors or from failure of the shareholders to elect the full number of
authorized directors) may, notwithstanding any resulting absence of a quorum of
directors, be filled by a majority vote of the Board of Directors remaining in
office, provided that the shareholder shall have the right, at any special
meeting called for such purpose prior to such action by the Board, to fill the
vacancy.  A director elected pursuant to this section shall serve until the next
shareholders' meeting held for the election of directors of the class to which
he shall have been appointed and until his successor is elected and qualified.

     3.7  NOTICE OF SHAREHOLDER NOMINEES.  Except as otherwise provided in
Section 3.8 of these By-laws, only persons who are nominated in accordance with
the procedures set forth in Article IV(E) of the Articles of Incorporation shall
be eligible for election as directors.

     3.8  DIRECTORS ELECTED BY PREFERRED SHAREHOLDERS.  Notwithstanding anything
in these By-laws to the contrary, whenever the holders of any one or more
classes or series of stock having a preference over the Common Stock as to
dividends or upon liquidation shall have the right, voting separately as a
class, to elect one or more directors of the Corporation, the provisions of the
Articles of Incorporation (as they may be duly amended from time to time) fixing
the rights and preferences of such preferred stock shall govern with respect to
the nomination, election, term, removal, vacancies or other related matters with
respect to such directors.

                                      -4-
<PAGE>
 
     3.9  COMPENSATION OF DIRECTORS.  Directors shall receive such compensation
for their services, in their capacity as directors, as may be fixed by
resolution of the Board of Directors; provided, however, that nothing herein
contained shall be construed to preclude any director from serving the
Corporation in any other capacity and receiving compensation therefor.

                                   SECTION 4

                             MEETINGS OF THE BOARD

     4.1  PLACE OF MEETINGS.  The meetings of the Board of Directors may be held
at such place within or without the State of Louisiana as a majority of the
directors may from time to time appoint.

     4.2  INITIAL MEETINGS.  Except as otherwise determined by the Board of
Directors, the first meeting of each newly-elected Board shall be held
immediately following the shareholders' meeting at which the Board, or any class
thereof, is elected and at the same place as such meeting, and no notice of such
first meeting shall be necessary for the newly-elected directors in order
legally to constitute the meeting.

     4.3  REGULAR MEETINGS; NOTICE.  Regular meetings of the Board may be held
at such times as the Board may form time to time determine.  Notice of regular
meetings of the Board of Directors shall be given, but no special form of notice
or time of notice shall be necessary.

     4.4  SPECIAL MEETINGS; NOTICE.  Special meetings of the Board may be called
by or at the direction of the Chairman of the Board or the President on
reasonable notice given to each director, either personally or by telephone,
mail, telex, telecopy or any other comparable form of facsimile communication.
Special meetings shall be called by the Secretary in like manner and on like
notice on the written request of a majority of the directors and if such officer
fails or refuses, or is unable within 24 hours to call a meeting when requested,
then the directors making the request may call the meeting on two days' written
notice given to each director.  The notice of a special meeting of directors
need not state it purpose or purposes, but if the notice states a purpose or
purposes and does not state a further purpose to consider such other business as
may properly come before the meeting, the business to be conducted at the
special meeting shall be limited to the purpose or purposes stated in the
notice.

     4.5  WAIVER OF NOTICE.  Directors present at any regular or special meeting
shall be deemed to have received, or to have waived, due notice thereof,
provided that a director who participates in a meeting by telephone (as
permitted by Section 4.9 hereof) shall not be deemed to have received or waived
due notice if, at the beginning of the meeting, he objects to the transaction of
any business because the meeting is not lawfully called.

     4.6  QUORUM.  A majority of the Board shall be necessary to constitute a
quorum for the transaction of business, and except as otherwise provided by law,
the Articles of Incorporation or these By-laws, the acts of a majority of the
directors present at a duly-called meeting at which a 

                                      -5-
<PAGE>
 
quorum is present shall be the acts of the board. If a quorum is not present at
any meeting of the Board of Directors, the directors present may adjourn the
meeting from time to time without notice other than announcement at the meeting,
until a quorum is present.

     4.7  WITHDRAWAL.  If a quorum was present when the meeting convened, the
directors present may continue to do business, taking action by vote of a
majority of a quorum as fixed in Section 4.6 hereof, until adjournment,
notwithstanding the withdrawal of enough directors to leave less than a quorum
as fixed in Section 4.6 hereof or the refusal of any director present to vote.

     4.8  ACTION BY CONSENT.  Any action that may be taken at a meeting of the
Board, or any committee thereof, may be taken by a consent in writing signed by
all of the directors or by all members of the committee, as the case may be, and
filed with the records of proceedings of the Board or committee.

     4.9  MEETINGS BY TELEPHONE OR SIMILAR COMMUNICATION.  Members of the Board
may participate at and be present at any meeting of the Board or any committee
thereof by means of conference telephone or similar communications equipment if
all persons participating in such meeting can hear and communicate with each
other.

                                   SECTION 5

     5.1  GENERAL.  The Board may designate one or more committees, each
committee to consist of two or more of the directors of the Corporation (and one
or more directors may be named as alternate members to replace any absent or
disqualified regular members), which, to the extent provided by resolution of
the Board or these By-laws, shall have and may exercise the powers of the Board
in the management of the business and affairs of the Corporation, and may have
power to authorize the seal of the Corporation to be affixed to documents, but
no such committee shall have power or authority to amend the Articles of
Incorporation, adopt an agreement of merger, consolidation or share exchange,
adopt or recommend to the shareholders the sale, lease or exchange of all or
substantially all of the Corporation's assets, recommend to the shareholders a
dissolution of the Corporation or a revocation of dissolution, remove directors,
or amend these By-laws; and unless the resolution expressly so provides, no such
committee shall have the power or authority to declare a dividend or authorize
the issuance of stock.  Such committee or committees shall have such name or
names as may be stated in these By-laws, or as may be determined, from time to
time, by the Board.  Any vacancy occurring in any such committee shall be filled
by the Board, but the President may designate another director to serve on the
committee pending action by the Board. Each such member of a committee shall
hold office during the term designated by the Board.

     5.2  COMPENSATION COMMITTEE.  The Board shall establish and maintain a
Compensation Committee consisting of two or more directors, each of whom (i)
shall be qualified to the extent appropriate as a "non-employee director" under
Rule 16b-3 of the Securities Exchange Commission 

                                      -6-
<PAGE>
 
and as an "outside director" under Section 162(m) of the Internal Revenue Code
and (ii) shall meet any further qualifications designated by the Board. The
Compensation Committee shall review and analyze the compensation of the
Corporation's executive officers; review and provide general guidance as to
compensation of the Corporation's other managers; evaluate the performance of
the Corporation's executive officers; administer the Corporation's Long-Term
Incentive Compensation Plan, including grants thereunder; and perform such other
services as may be designated by the Board.

     5.3  AUDIT COMMITTEE.  The Board shall establish an Audit Committee
consisting of at least two directors, a majority of whom are not officers or
employees of the Corporation or any of its affiliates.  The Audit Committee
shall (i) facilitate communication among the Corporation's directors,
management, independent accountants and internal auditing personnel regarding
matters relating to financial accounting, reporting and controls, (ii) assist
the Board of Directors in fulfilling its fiduciary responsibilities as to
accounting policies and reporting practices of the Corporation and all
subsidiaries and the sufficiency of auditing practices with respect thereto by,
among other things, reviewing the scope of audit coverage, including
consideration of the Corporation's accounting practices and procedures and
system of internal accounting controls and reporting to the Board with respect
thereto, (iii) operate as the Board's principal agent in ensuring the
independence of the Corporation's independent accountants, the integrity of
management and the adequacy of disclosure to shareholders, and (iv) perform such
other services as may be designated by the Board.

                                   SECTION 6

                            REMOVAL OF BOARD MEMBERS

     Directors may be removed in accordance with the applicable provisions of
the Articles of Incorporation.

                                   SECTION 7

                                    NOTICES

     7.1  FORM OF DELIVERY.  Whenever under the provisions of law, the Articles
of Incorporation or these By-laws notice is required to be given to any
shareholder or director, it shall not be construed to mean personal notice
unless otherwise specifically provided in the Articles of Incorporation or these
By-laws, but such notice may be given by mail, addressed to such shareholder or
director at his address as it appears on the records of the Corporation, with
postage thereon prepaid, or in such other manner as may be specified in these
By-laws.  Notices given by mail shall be deemed to have been given at the time
they are deposited in the United States mail, and all other notices shall be
deemed to have been give upon receipt.

     7.2  WAIVER.  Whenever any notice is required to be given by law, the
Articles of Incorporation or these By-laws, a waiver thereof in writing signed
by the person or persons entitled 

                                      -7-
<PAGE>
 
to such notice, whether before or after the time stated therein, shall be deemed
equivalent thereto.

In addition, notice shall be deemed to have been given to, or waived by, any
shareholder or director who attends a meeting of shareholders or directors in
person, or is represented at such meeting by proxy, without protesting at the
commencement of the meeting the transaction of any business because the meeting
is not lawfully called or convened.

                                   SECTION 8

                                    OFFICERS

     8.1  DESIGNATIONS.  The officers of the Corporation shall be elected by the
directors and shall be the President, Secretary and Treasurer.  The Board of
Directors may appoint a Chief Executive Officer, a Chief Operating Officer, a
Chief Accounting Officer, one or more Vice Presidents and such other officers as
it shall deem necessary.  Officers shall hold their offices for such terms and
shall exercise such powers and perform such duties as shall be determined from
time to time by the Board.  To the extent permitted by law, more than one office
may be held by a single person.

     8.2  TERM OF OFFICE.  The officers of the Corporation shall hold office at
the pleasure of the Board of Directors.  Except as otherwise provided in the
resolution of the Board of Directors electing any officer, each officer shall
hold office until the first meeting of the Board of Directors after the annual
meeting of shareholders next succeeding his or her election, and until his or
her successor is elected and qualified or until his or her earlier resignation
or removal.  Any officer may resign at any time upon written notice to the
Board, Chairman of the Board, President or Secretary of the Corporation.  Such
resignation shall take effect at the time specified therein and acceptance of
such resignation shall not be necessary to make it effective.  The Board may
remove any officer with or without cause at any time.  Any such removal shall be
without prejudice to the contractual rights of such officers, if any, with the
Corporation, but the election of an officer shall not in and of itself create
contractual rights.  Any vacancy occurring in any office of the Corporation by
death, resignation, removal or otherwise may be filled for the unexpired
position of the term by the Board at any regular or special meeting.

     8.3  THE CHAIRMAN OF THE BOARD.  The Board may appoint a Chairman of the
Board who shall preside at meetings of the Board of Directors and the
shareholders and perform such other duties as may be designated by the Board of
Directors or these By-laws.  The Chairman of the Board shall not, solely by
virtue of such position, be an officer of the Corporation but may be designated
an officer by the Board of Directors.

     8.4  THE PRESIDENT.  The President shall, unless otherwise provided by the
Board, have general and active responsibility for the management of the business
of the Corporation, shall be the chief executive and chief operating officer of
the Corporation, shall supervise the daily operations 

                                      -8-
<PAGE>
 
of the business of the Corporation and shall ensure that all orders, policies
and resolutions of the Board are carried out.

     8.5  THE VICE PRESIDENTS.  The Vice Presidents (if any) shall have such
designations and perform such duties as the President or the Board of Directors
shall prescribe.

     8.6  THE SECRETARY.  The Secretary shall attend all meetings of the Board
of Directors and all meetings of the shareholders and record all votes and the
minutes of all proceedings in a book to be kept for that purpose.  He shall
give, or cause to be given, notice of all meetings of the shareholders and
regular and special meetings of the Board, and shall perform such other duties
as may be prescribed by the Board or President.  He shall keep in safe custody
the seal of the Corporation, if any, and affix such seal to any instrument
requiring it.

     8.7  THE ASSISTANT SECRETARY.  The Assistant Secretary shall have the same
powers and duties as the Secretary and shall perform such other duties as may be
prescribed by the Board or President.

     8.8  THE TREASURER.  The Treasurer shall have the custody of the corporate
funds and shall keep or cause to be kept full and accurate accounts of receipts
and disbursements in books belonging to the Corporation and shall deposit all
monies and other valuable effects in the name and to the credit of the
Corporation in such depositories as may be designated by the Board of Directors.
He shall keep a proper accounting of all receipts and disbursements and shall
disburse the funds of the Corporation only for proper corporate purposes or as
may be ordered by the Board and shall render to the President and the Board at
the regular meetings of the Board, or whenever they may require it, an account
of all his transactions as Treasurer and of the financial condition and results
of operations of the Corporation.

                                   SECTION 9

                                     STOCK

     9.1  CERTIFICATES.  Every holder of stock in the Corporation shall be
entitled to have a certificate signed by the President or a Vice President and
the Secretary or an Assistant Secretary evidencing the number and class (and
series, if any) of shares owned by him, containing such information as required
by law and bearing the seal of the Corporation.  As provided in the Articles of
Incorporation, the Board of Directors may approve the use of dual forms of stock
certificates, one for issuance to U.S. citizen stockholders, and one for
issuance to non-U.S. citizen stockholders.  If any stock certificate is manually
signed by a transfer agent or registrar other than the Corporation itself or an
employee of the Corporation, the signature of any such officer may be a
facsimile.  In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate shall have ceased
to be an officer, transfer agent or registrar of the Corporation before such
certificate is issued, it may be issued by the Corporation with the same 

                                      -9-
<PAGE>
 
effect as if such person or entity were an officer, transfer agent or registrar
of the Corporation on the date of issue.

     9.2  MISSING CERTIFICATES.  The President or any Vice President may direct
a new certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the Corporation alleged to have been lost,
stolen or destroyed, upon the Corporation's receipt of an affidavit of that fact
from the person claiming the certificate of stock to be lost, stolen or
destroyed. As a condition precedent to the issuance of a new certificate or
certificates, the officers of the Corporation shall, unless dispensed with by
the President, require the owner of such lost, stolen or destroyed certificate
or certificates, or his legal representative, to (i) give the Corporation a bond
or (ii) enter into a written indemnity agreement, in each case in an amount
appropriate to indemnify the Corporation against any claim that may be made
against the Corporation with respect to the certificate alleged to have been
lost, stolen or destroyed.

     9.3  TRANSFERS.  The shares of stock of the Corporation shall be
transferable only on the books of the Corporation by the holders thereof in
person or by their duly authorized attorneys or legal representatives upon
surrender and cancellation of certificates for a like number of shares. Upon
surrender to the Corporation or the transfer agent of the Corporation of a
certificate for shares duly endorsed or accompanied by proper evidence of
succession, assignment or authority to transfer, it shall be the duty of the
Corporation to issue a new certificate to the person entitled thereto, cancel
the old certificate and record the transaction upon its books, provided that as
a condition precedent to the transfer of shares on the records of the
Corporation, the Corporation may require representations or other proof of the
identity and citizenship of any prospective stockholder and may restrict
transfers to non-U.S. citizens as provided in the Articles of Incorporation.

                                   SECTION 10

                         DETERMINATION OF SHAREHOLDERS

     For the purpose of determining shareholders entitled to notice of and to
vote at a meeting, or to receive a dividend, or to receive or exercise
subscription or other rights, or to participate in a reclassification of stock,
or in order to make a determination of shareholders for any other proper
purpose, the Board of Directors may fix in advance a record date for
determination of shareholders for such purpose, such date to be not more than 60
days and, if fixed for the purpose of determining shareholders entitled to
notice of and to vote at a meeting, not less than 10 days, prior to the date on
which the action requiring the determination of shareholders is to be taken.

                                   SECTION 11

                                INDEMNIFICATION

     11.  DEFINITIONS.  As used in this section the following terms shall have
the meanings set forth below:

                                      -10-
<PAGE>
 
          (a) "Board" - the Board of Directors of the Corporation.

          (b) "Claim" - any threatened, pending or completed claim, action,
suit, or proceeding, whether civil, criminal, administrative or investigative
and whether made judicially or extra-judicially, or any separate issue or matter
therein, as the context requires.

          (c) "Determining Body" - (i) those members of the Board who are not
named as parties to the Claim for which indemnification is being sought
("Impartial Directors"), if there are at least three Impartial Directors, (ii) a
committee of at least three Impartial Directors appointed by the Board
(regardless whether the members of the Board of Directors voting on such
appointment are Impartial Directors) or (iii) if there are fewer than three
Impartial Directors or if the Board of Directors or the committee appointed
pursuant to clause (ii) of this paragraph so directs (regardless whether the
members thereof are Impartial Directors), independent legal counsel, which may
be the regular outside counsel of the Corporation.

          (d) "Disbursing Officer" - the President of the Corporation or, if the
President is a party to the Claim for which indemnification is being sought, any
officer not a party to such Claim who is designated by the President to be the
Disbursing Officer with respect to indemnification requests related to the
Claim, which designation shall be made promptly after receipt of the initial
request for indemnification with respect to such Claim.

          (e) "Expenses" - any expenses or costs, including, without limitation,
attorney's fees, judgments, punitive or exemplary damages, fines and amounts
paid in settlement.

          (f) "Indemnitee" - each person who is or was a director or officer of
the Corporation.

     11.2  INDEMNITY.

           (a) To the extent such Expenses exceed the amounts reimbursed or paid
pursuant to policies of liability insurance maintained by the Corporation, the
Corporation shall indemnify each Indemnitee against any Expenses actually and
reasonably incurred by him (as they are incurred) in connection with any Claim
either against him or as to which he is involved solely as a witness or person
required to give evidence, by reason of his position (i) as a director or
officer of the Corporation, (ii) as a director or officer of any subsidiary of
the Corporation, (iii) as a fiduciary with respect to any employee benefit plan
of the Corporation, or (iv) as a director, officer, partner, employee or agent
of another corporation, partnership, joint venture, trust or other for-profit or
not-for-profit entity or enterprise, if such position is or was held at the
request of the Corporation, whether relating to service in such position before
or after the effective date of this Section, if he (i) is successful in his
defense of the claim on the merits or otherwise or (ii) has been found by the
Determining Body (acting in good faith) to have met the Standard of Conduct
(defined below); provided that (A) the amount otherwise payable by the
Corporation may be reduced by the Determining Body to such amount as it deems
proper if it determines that the Claim involved the 

                                      -11-
<PAGE>
 
receipt of a personal benefit by Indemnitee, and (B) no indemnification shall be
made in respect of any Claim as to which Indemnitee shall have been adjudged by
a court of competent jurisdiction, after exhaustion of all appeals therefrom, to
be liable for willful or intentional misconduct in the performance of his duty
to the Corporation or to have obtained an improper personal benefit, unless, and
only to the extent that, a court shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
Indemnitee is fairly and reasonably entitled to indemnity for such Expenses as
the court deems proper.

          (b) For purposes of this Section 11, the Standard of Conduct is met
when the conduct by an Indemnitee with respect to which a Claim is asserted was
conduct that was in good faith and that he reasonably believed to be in, or not
opposed to, the best interest of the Corporation, and, in the case of a criminal
action or proceeding, that he had no reasonable cause to believe was unlawful.
The termination of any Claim by judgment, order, settlement, conviction, or upon
a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that Indemnitee did not meet the Standard of Conduct.

          (c) Promptly upon becoming aware of the existence of any Claim as to
which he may be indemnified hereunder, Indemnitee shall notify the President of
the Corporation of the Claim and whether he intends to seek indemnification
hereunder.  If such notice indicates that Indemnitee does so intend, the
President shall promptly advise the Board thereof and notify the Board that the
establishment of the Determining Body with respect to the Claim will be a matter
presented at the next regularly scheduled meeting of the Board.  Such a meeting
is to be held within 90 calendar days of the date of Indemnitee's request.  If a
meeting of the Board of Directors is not regularly scheduled within 120 calendar
days of such request, the President shall cause a special meeting of the Board
of Directors to be called within such period in accordance with these By-laws.
After the Determining Body has been established the President shall inform the
Indemnitee thereof and Indemnitee shall immediately provide the Determining Body
with all facts relevant to the Claim known to him.  No later than the 45th day
(the "Determination Date") after its receipt of such information, together with
such additional information as the Determining Body may request of Indemnitee,
the Determining Body shall determine, and shall advise Indemnitee of its
determination, whether Indemnitee has met the Standard of Conduct.

          (d) During such 45-day period, Indemnitee shall promptly inform the
Determining Body upon his becoming aware of any relevant facts not theretofore
provided by him to the Determining Body, unless the Determining Body has
obtained such facts by other means.  The providing of such facts to the
Determining Body shall not begin a new 45-day period.

          (e) The Determining Body shall have no authority to revoke a
determination that Indemnitee met the Standard of Conduct unless Indemnitee (i)
submits fraudulent information to the Determining Body at any time during the 45
days prior to the Determination Date or (ii) fails to comply with the provisions
of subsections (c) or (d) hereof, including without limitation Indemnitee's
obligation to submit information or documents relevant to the Claim reasonably
requested by the Determining Body prior to the Determination Date.

                                      -12-
<PAGE>
 
          (f) In the case of any Claim not involving a proposed, threatened or
pending criminal proceeding,

          (i) if Indemnitee has, in the good faith judgment of the Determining
Body, met the Standard of Conduct, the Corporation may, in its sole discretion
after notice to Indemnitee, assume all responsibility for the defense of the
Claim, and, in any event, the Corporation and the Indemnitee each shall keep the
other informed as to the progress of the defense, including prompt disclosure of
any proposals for settlement; provided that if the Corporation is a party to the
Claim and Indemnitee reasonably determines that there is a conflict between the
positions of the Corporation and Indemnitee with respect to the Claim, then
Indemnitee shall be entitled to conduct his defense, with counsel of his choice;
and provided further that Indemnitee shall in any event be entitled at his
expense to employ counsel chosen by him to participate in the defense of the
Claim; and

          (ii) the Corporation shall fairly consider any proposals by Indemnitee
for settlement of the Claim. If the Corporation (A) proposes a settlement
acceptable to the person asserting the Claim, or (B) believes a settlement
proposed by the person asserting the Claim should be accepted, it shall inform
Indemnitee of the terms thereof and shall fix a reasonable date by which
Indemnitee shall respond. If Indemnitee agrees to such terms, he shall execute
such documents as shall be necessary to effect the settlement. If he does not
agree he may proceed with the defense of the Claim in any manner he chooses, but
if he is not successful on the merits or otherwise, the Corporation's obligation
to indemnify him for any Expenses incurred following his disagreement shall be
limited to the lesser of (A) the total Expenses incurred by him following his
decision not to agree to such proposed settlement or (B) the amount the
Corporation would have paid pursuant to the terms of the proposed settlement.
If, however, the proposed settlement would impose upon Indemnitee any
requirement to act or refrain from acting that would materially interfere with
the conduct of his affairs, Indemnitee may refuse such settlement and proceed
with the defense of the Claim, if he so desires, at the Corporation's expense
without regard to the limitations imposed by the preceding sentence. In no
event, however, shall the Corporation be obligated to indemnify Indemnitee for
any amount paid in a settlement that the Corporation has not approved.

          (g) In the case of a Claim involving a proposed, threatened or pending
criminal proceeding, Indemnitee shall be entitled to conduct the defense of the
claim, and to make all decisions with respect thereto, with counsel of his
choice; provided, however, that the Corporation shall not be obligated to
indemnify Indemnitee for an amount paid in settlement that the Corporation has
not approved.

          (h) After notifying the Corporation of the existence of a Claim,
Indemnitee may from time to time request the Corporation to pay the Expenses
(other than judgments, fines, penalties or amounts paid in settlement) that he
incurs in pursuing a defense of the Claim prior to the time that the Determining
Body determines whether the Standard of Conduct has been met.  If the Disbursing
Officer believes the amount requested to be reasonable, he shall pay to
Indemnitee the amount requested (regardless of Indemnitee's apparent ability to
repay such amount) upon receipt of an 

                                      -13-
<PAGE>
 
undertaking by or on behalf of Indemnitee to repay such amount if it shall
ultimately be determined that he is not entitled to be indemnified by the
Corporation under the circumstances. If the disbursing Officer does not believe
such amount to be reasonable, the Corporation shall pay the amount deemed by him
to be reasonable and Indemnitee may apply directly to the Determining Body for
the remainder of the amount requested.

          (i) After the Determining Body has determined that the Standard of
Conduct was met, for so long as and to the extent that the Corporation is
required to indemnify Indemnitee under this Agreement, the provisions of
paragraph (h) shall continue to apply with respect to Expenses incurred after
such time except that (i) no undertaking shall be required of Indemnitee and
(ii) the Disbursing Officer shall pay to Indemnitee such amount of any fines,
penalties or judgments against him which have become final as the Corporation is
obligated to indemnify him.

          (j) Any determination by the Corporation with respect to settlements
of a Claim shall be made by the Determining Body.

          (k) The Corporation and Indemnitee shall keep confidential, to the
extent permitted by law and their fiduciary obligations, all facts and
determinations provided or made pursuant to or arising out of the operation of
this Section, and the Corporation and Indemnitee shall instruct its or his
agents and employees to do likewise.

     11.3  ENFORCEMENT.

          (a) The rights provided by this Section shall be enforceable by
Indemnitee in any court of competent jurisdiction.

          (b) If Indemnitee seeks a judicial adjudication of his rights under
this Section, Indemnitee shall be entitled to recover from the Corporation, and
shall be indemnified by the Corporation against, any and all Expenses actually
and reasonably incurred by him in connection with such proceeding but only if he
prevails therein.  If it shall be determined that Indemnitee is entitled to
receive part but not all of the relief sought, then the Indemnitee shall be
entitled to be reimbursed for all Expenses incurred by him in connection with
such judicial adjudication if the amount to which he is determined to be
entitled exceeds 50% of the amount of his claim.  Otherwise, the Expenses
incurred by Indemnitee in connection with such judicial adjudication shall be
appropriately prorated.

          (c) In any judicial proceeding described in this subsection, the
Corporation shall bear the burden of proving that Indemnitee is not entitled to
any Expenses sought with respect to any Claim.

     11.4  SAVING CLAUSE.  If any provision of this Section is determined by a
court having jurisdiction over the matter to require the Corporation to do or
refrain from doing any act that is in violation of applicable law, the court
shall be empowered to modify or reform such provision so that, 

                                      -14-
<PAGE>
 
as modified or reformed, such provision provides the maximum indemnification
permitted by law, and such provision, as so modified or reformed, and the
balance of this Section, shall be applied in accordance with their terms.
Without limiting the generality of the foregoing, if any portion of this Section
shall be invalidated on any ground, the Corporation shall nevertheless indemnify
an Indemnitee to the full extent permitted by any applicable portion of this
Section that shall not have been invalidated and to the full extent permitted by
law with respect to that portion that has been invalidated.

     11.5  NON-EXCLUSIVITY.

          (a) The indemnification and advancement of Expenses provided by or
granted pursuant to this Section shall not be deemed exclusive of any other
rights to which Indemnitee is or may become entitled under any statute, article
of incorporation, by-law, authorization of shareholders or directors, agreement,
or otherwise.

          (b) It is the intent of the Corporation by this Section to indemnify
and hold harmless Indemnitee to the fullest extent permitted by law, so that if
applicable law would permit the Corporation to provide broader indemnification
rights than are currently permitted, the Corporation shall indemnify and hold
harmless Indemnitee to the fullest extent permitted by applicable law
notwithstanding that the other terms of this Section would provide for lesser
indemnification.

     11.6  SUCCESSORS AND ASSIGNS.  This Section shall be binding upon the
Corporation, its successors and assigns, and shall inure to the benefit of the
Indemnitee's heirs, personal representatives, and assigns and to the benefit of
the Corporation, its successors and assigns.

     11.7  INDEMNIFICATION OF OTHER PERSONS.  The Corporation may indemnify any
person not covered by Sections 11.1 through 11.6 to the extent provided in a
resolution of the Board or a separate section of these By-laws.

                                   SECTION 12

                       ADOPTION AND AMENDMENT OF BY-LAWS

     By-laws of the Corporation may be adopted and amended as provided in the
Articles of Incorporation.

                                      -15-
<PAGE>
 
                                   SECTION 13

                                 MISCELLANEOUS

     13.1  DIVIDENDS.  Except as otherwise provided by law, the Articles of
Incorporation or these By-laws, dividends upon the stock of the Corporation may
be declared by the Board of Directors at any regular or special meeting.
Dividends may be paid in cash, property, or shares of stock, subject to the
limitations specified in the Articles of Incorporation.

     13.2  VOTING OF SHARES OWNED BY CORPORATION.  Unless otherwise directed by
the Board, any shares of capital stock issued by a wholly-owned subsidiary of
the Corporation may be voted by the President of the Corporation, or by any

                              W I T N E S S E T H:
                              - - - - - - - - - -

     NOW, THEREFORE, for and in consideration of the mutual covenants,
agreements and undertakings herein contained, Borrower, Banks and Agent hereby
agree as follows:

      Section 1.    Relation to Prior Credit Arrangements.  Subject to the terms
and conditions hereof, each Bank severally agrees that Borrower's obligations as
evidenced by the Revised Credit Agreement and the Prior Notes shall be modified
and restated in their entirety on the terms and conditions set forth herein.  To
the extent there is any conflict between the Revised Credit Agreement and this
Agreement or the Prior Notes and the Notes, the provisions of this Agreement and
the Notes shall govern.  To the extent this Agreement or the Notes is or are
silent on any matter or provision contained in the Revised Credit Agreement or
the Prior Notes, such matter or provision 

                                       2
<PAGE>
 
of the Revised Credit Agreement or the Prior Notes shall be deemed to be
revoked. Borrower and Banks acknowledge and agree that (i) the modification and
restatement of the Obligations under the terms and conditions set forth herein
do not constitute a payment, prepayment or novation of the Obligations evidenced
by the Revised Credit Agreement and the Prior Notes and (ii) the Obligations
continue to be secured by the Existing Security with the original rank and
priority thereof.

      1.1 Revolving Credit Facility.  Banks shall make available to Borrower a
revolving line of credit (the "Revolving Credit Facility") in the maximum
principal amount of TWENTY MILLION AND NO/100 DOLLARS ($20,000,000.00) (as
modified pursuant to Section 4.4 below, the "Revolving Commitment"), which
Revolving Credit Facility may be drawn upon by Borrower on any Business Day of
Banks during the period from the date hereof until and including December 31,
1999, or such earlier date as may be fixed by Borrower on at least one (1)
Business Day's telephonic notice to Agent, to be confirmed in writing by
Borrower, in the form of the issuance by Banks on behalf of and for the account
of Borrower of irrevocable stand-by letters of credit in the form provided for
by, and containing such terms and conditions as are acceptable to Banks and in
such amounts as Borrower may from time to time request (each such letter of
credit, as well as any letters of credit issued pursuant to and in accordance
with the Revised Credit Agreement or any predecessor agreement which remain
outstanding on the date hereof, being hereinafter referred to individually as a
"Letter of Credit" and collectively as the "Letters of Credit") or in the form
of actual fundings to Borrower by Banks in such amounts as Borrower may from
time to time request (each such funding, as well as the aggregate amount of the
Prior Notes previously funded by Banks and outstanding on the date hereof, being
hereinafter referred to individually as an "Advance" and collectively as the
"Advances"), so long as (a) the aggregate principal amount of all Letters of
Credit outstanding at any one time does not exceed the LC Commitment and (b) the
aggregate principal 

                                       3
<PAGE>
 
amount of all Letters of Credit and of all Advances outstanding at any one time
does not exceed the Revolving Commitment. The Revolving Commitment available to
Borrower from time to time under the Revolving Credit Facility shall be reduced
by the aggregate of the face amount of any outstanding Letters of Credit and of
all unpaid Advances made by Banks to Borrower pursuant to this Agreement and the
remaining amount of the Revolving Commitment shall constitute the "Unused
Commitment". Any draws made under the Letters of Credit by the beneficiaries
thereof shall constitute Advances as defined in this Agreement. The Unused
Commitment available under the Revolving Credit Facility shall be restored but
simultaneously reduced by the amount of any Advances which are made to Borrower
to reimburse Banks for draws under the Letters of Credit.

      1.2 Borrowing Procedure Under the Revolving Credit Facility.  Agent shall
receive at least one (1) Business Day's prior telephonic notice from Borrower
(to be confirmed in writing by Borrower) of each proposed Letter of Credit and
of each Advance to be issued under the Revolving Credit Facility.  If all
conditions precedent to the issuance of any such Letter of Credit or any such
Advance have been met, Agent will, without any further consent or approval from
Banks, or either one of them, on the date requested make each Letter of Credit
or Advance available to Borrower at Agent's office at 201 St. Charles Avenue,
New Orleans, Louisiana 70170, and each Letter of Credit or Advance shall be
shared equally by Banks.

      1.3 Terms and Conditions Governing Letters of Credit.  The terms and
conditions governing the issuance of Letters of Credit by Banks on behalf of and
for the account of Borrower shall be provided for by Agent in its standard form
of Application for Stand-By Letter of Credit, a copy of which is attached hereto
as Exhibit "A", with appropriate insertions and such additional terms and
conditions governing the issuance of specific Letters of Credit as may be agreed
upon by Borrower and Agent at the time of Borrower's request to Agent for the
issuance thereof.  Upon 

                                       4
<PAGE>
 
Agent's issuance of a Letter of Credit, one-half (1/2) of the amount of such
Letter of Credit shall automatically be deemed to have been provided by Whitney,
and, without the necessity of further documentation transferring an interest in
the Letter of Credit to Whitney, Whitney shall possess a one-half (1/2) interest
in all rights and obligations accruing to and incurred by Agent with respect to
such Letter of Credit. Whitney shall record its one-half (1/2) share of any
draws on the Letter of Credit on the schedule attached to its Revolving Note as
provided in Section 2.1 below.

      Section 2.    Notes Evidencing Borrowings.

      2.1 Notes.  The Advances (including, without limitation, the outstanding
indebtedness of Borrower to Banks under the Prior Notes which, as provided in
Section 1.1, shall be deemed an "Advance" hereunder) shall be evidenced by two
(2) promissory notes of Borrower payable to the order of First NBC and Whitney,
respectively, each in the original principal amount of TEN MILLION AND NO/100
DOLLARS ($10,000,000.00) and in the forms set forth as Exhibits "B" and "C" to
this Agreement (each such note, together with any and all renewals,
modifications, extensions, amendments, supplements and/or substitutions
therefor, being sometimes referred to herein individually as a "Note" and
collectively as the "Notes"), with appropriate insertions, each of which shall
be dated the date hereof and shall be payable in full on December 31, 1999.  All
Advances made by Banks to Borrower pursuant to this Agreement and all payments
of principal shall be recorded by Banks on the schedule attached to each Note,
but Banks' failure to record or to record correctly such Advances shall in no
way affect Borrower's obligation to repay same.

      2.2 No Novation.  The execution and delivery of the Notes shall not
constitute a payment, prepayment or novation of the obligations of Borrower
heretofore evidenced by the Prior Notes, but does constitute a renewal and
restatement of the Prior Notes in their entirety.

                                       5
<PAGE>
 
      Section 3.    Interest and Fees.

      3.1 Interest -- Revolving Credit Facility.  In the absence of an Event of
Default, the unpaid principal of the Notes shall bear interest until paid at the
Prime Rate, adjusted daily, or the LIBO Rate, or some combination thereof, as
specified in Section 3.6 below.  Interest prior to maturity shall be payable
quarterly in arrears on the last day of each March, June, September and December
commencing June 30, 1997, and continuing until maturity.  Interest after
maturity of the Notes for any reason whatsoever shall be increased to the Prime
Rate plus three percent (3%) and shall be payable on demand.  Upon the issuance
of a Letter of Credit by Agent on behalf of and for the account of Borrower, a
fee of one percent (1%) per annum on the principal amount of such Letter of
Credit shall be payable by Borrower for the number of days such Letter of Credit
is to remain outstanding.  A fee on the Unused Commitment of three-eighths (3/8)
of one percent (1%) per annum shall be payable by Borrower quarterly in arrears
on the last day of each March, June, September and December commencing June 30,
1997, and continuing until maturity.

      3.2 Default Rate.  If an Event of Default shall occur in the payment on or
before the due date of any principal or interest due hereunder or under any of
the other Loan Documents, including, without limitation, the Notes, Borrower
will pay interest thereon (retroactively) from the date of the Event of Default
on such payment up to the date of the actual payment (as well after as before
judgment) at the Prime Rate plus three percent (3%) (the "Default Rate"),
without regard to whether there has been an acceleration of the payment of
principal.  Such interest at the Default Rate shall be payable on demand.

      3.3 Prime Rate.  "Prime Rate" shall mean that index which shall be
established by Citibank, N.A. at New York, New York as its "prime rate".  Each
change in the interest rate on each Note shall take effect on the effective date
of the change in the Prime Rate.

      3.4 Origination Fee.  No origination fee shall be payable by Borrower.

      3.5 Method of Calculating Interest and Fees.  Interest at the Prime Rate
and any fee shall be computed on the basis of a year consisting of 365 days and
paid for actual days elapsed, and interest at the LIBO Rate shall be computed on
the basis of a year consisting of 360 days.

      3.6 Interest Rate Options.  Until an Event of Default occurs, Borrower
shall have the following interest rate options:

          (a) Advances to Borrower under the Revolving Credit Facility may from
     time to time be (i) LIBO Rate Advances, (ii) Prime Rate Advances, or (iii)
     any combination thereof, as determined by Borrower with respect to its
     Advances and noticed to Agent in accordance with paragraphs (b), (c), and
     (d) below; provided that no Advance shall be made to Borrower as a LIBO
     Rate Advance under the Revolving Credit Facility after the day that is one
     month prior to the Termination Date.  For purposes of this paragraph (a),
     an Advance shall be deemed "made" upon an initial borrowing by Borrower
     under paragraph (b) below, any conversion of such Advance under paragraph
     (c) below, and upon any continuation of such Advance under paragraph (d)
     below.

          (b) With respect to any new Advance, Borrower shall provide Agent with
     telephonic notice of its intended borrowing, which notice must be received
     by Agent prior to 10:00 A.M., New Orleans time, at least one (1) Business
     Day prior to the requested Borrowing Date, which notice shall specify (i)
     the amount to be borrowed, (ii) the requested Borrowing Date, (iii) whether
     the borrowing is to be of LIBO Rate Advances or Prime Rate Advances or a
     combination thereof, (iv) the respective amounts of each such type of
     Advance, and (v) if the borrowing is to be entirely or partly of LIBO Rate
     Advances, the respective lengths of the Interest Periods therefor.

                                       7
<PAGE>
 
          (c) Borrower may elect from time to time to convert any of its LIBO
     Rate Advances to Prime Rate Advances by giving Agent telephonic notice of
     such election, which notice must be received by Agent prior to 10:00 A.M.,
     New Orleans time, at least one (1) Business Day prior to the requested
     conversion; provided that any such conversion, of LIBO Rate Advances shall
     only be made on the last day of an Interest Period with respect thereto.
     Borrower may elect from time to time to convert any of its Prime Rate
     Advances to LIBO Rate Advances by giving Agent telephonic notice of such
     election, which notice must be received by Agent prior to 10:00 A.M., New
     Orleans time, at least one (1) Business Day prior to the requested
     conversion.  Any such notice of conversion to LIBO Rate Advances shall
     specify the length of the initial Interest Period thereof and the amount of
     the Prime Rate Advance to be converted.  All or any part of Borrower's
     outstanding LIBO Rate Advances and Prime Rate Advances may be converted as
     provided herein; provided that (i) no Prime Rate Advance may be converted
     into a LIBO Rate Advance when any Event of Default has occurred and is
     continuing, (ii) partial conversions of Prime Rate Advances to LIBO Rate
     Advances shall be in an aggregate principal amount of $500,000 or a whole
     multiple of $100,000 in excess thereof, (iii) partial conversions of LIBO
     Rate Advances to Prime Rate Advances shall be in an aggregate principal
     amount of $500,000 or a whole multiple of $100,000 in excess thereof, (iv)
     no Prime Rate Advance under the Revolving Credit Facility may be converted
     into a LIBO Rate Advance after the date that is one month prior to the
     Termination Date, and (v) any such conversion may only be made if, after
     giving effect thereto, paragraph (e) shall not have been contravened.

          (d) Any LIBO Rate Advances may be continued as such upon the
     expiration of an Interest Period with respect thereto by Borrower giving
     Agent telephonic notice, which

                                       8
<PAGE>
 
     notice must be received by Agent prior to 10:00 A.M., New Orleans time, at
     least one (1) Business Day prior to the requested continuation; provided,
     that (i) no LIBO Rate Advance may be continued as such when any Event of
     Default has occurred and is continuing, (ii) no LIBO Rate Advances under
     the Revolving Credit Facility may be continued as such after the date which
     is one month prior to the Termination Date, and (iii) any such continuation
     shall be made only if, after giving effect thereto, paragraph (e) shall not
     be contravened. If Borrower shall fail to give such notice or if such
     continuation is not permitted, then Borrower shall be deemed to have
     requested that the LIBO Rate Advance be converted automatically to a Prime
     Rate Advance on the last day of the then current Interest Period with
     respect thereto.

          (e) All borrowings, conversions and continuations of Advances
     hereunder by Borrower and all selections of Interest Periods hereunder by
     Borrower shall be in such amounts and be made pursuant to such elections so
     that, after giving effect thereto, the aggregate principal amount of the
     Advances to Borrower constituting each LIBO Rate tranche (i.e., LIBO Rate
     Advances made on the same day and having the same Interest Period) shall be
     equal to $500,000 or a whole multiple of $100,000 in excess thereof.  If
     Borrower has no Prime Rate Advances outstanding, Borrower may have a
     maximum of five (5) LIBO Rate tranches in aggregate in effect at any one
     time, and, if Borrower has Prime Rate Advances outstanding, Borrower may
     have a maximum of four (4) LIBO Rate tranches in aggregate in effect at any
     one time.

          (f) Each determination of an interest rate by Agent pursuant to any
     provision of this Agreement shall be conclusive and binding on Borrower in
     the absence of manifest error. 

                                       9
<PAGE>
 
     Agent shall, at the request of Borrower, deliver to Borrower a statement
     showing the quotations used by Agent in determining the LIBO Rate.

          (g) If prior to the first day of any Interest Period, Agent shall have
     determined (which determination shall be conclusive and binding upon
     Borrower) that either:

          (i)  adequate and reasonable means do not exist for ascertaining the
               LIBO Rate for such Interest Period; or

          (ii) the interest rate determined for such Interest Period does not
               adequately and fairly reflect the cost to Banks (as conclusively
               certified by Agent) of making, maintaining or funding their LIBO
               Rate Advances during such Interest Period, in either case with
               respect to (i) proposed Advances that Borrower has requested be
               made as LIBO Rate Advances, (ii) LIBO Rate Advances that will
               result from the requested conversion of Prime Rate Advances  into
               LIBO Rate Advances, or (iii) the continuation of LIBO Rate
               Advances beyond the expiration of the then current Interest
               Period with respect thereto;

     Agent shall give telephonic notice thereof to Borrower as soon as
     practicable thereafter. Unless Borrower notifies Agent upon receipt of such
     notice that it wishes to rescind or modify its request, Agent shall arrange
     that (x) any affected LIBO Rate Advances requested by Borrower shall be
     made as Prime Rate Advances, (y) any Prime Rate Advances to Borrower that
     were to have been converted to LIBO Rate Advances shall be continued as, or
     converted to, Prime Rate Advances, and (z) all outstanding LIBO Rate
     Advances to Borrower shall be converted, on the last day of the then
     current Interest Period with respect thereto, to Prime Rate Advances.
     Until such notice has been withdrawn by Agent, no further LIBO Rate
     Advances shall be made to Borrower, nor shall Borrower have the right to
     convert Prime Rate Advances to LIBO Rate Advances.

          (h) Notwithstanding any other provision in this Agreement, if the
     adoption of or any change in any law or regulation or in the interpretation
     or application thereof (whether or not having the force of law) shall make
     it unlawful or impossible for Bank to make, 

                                       10
<PAGE>
 
     maintain or fund LIBO Rate Advances as contemplated by this Agreement: (a)
     the commitment of Banks hereunder to make LIBO Rate Advances, continue LIBO
     Rate Advances as such and convert Prime Rate Advances to LIBO Rate Advances
     shall forthwith be cancelled; (b) the Advances then outstanding as LIBO
     Rate Advances, if any, shall be converted automatically to Prime Rate
     Advances on the respective last days of the then current Interest Periods
     with respect to such Advances or within such earlier period as required by
     law; and (c) Borrower shall pay Banks such amounts, if any, as may be
     required pursuant to paragraph (i) below.

          (i) Borrower agrees to indemnify Banks and to hold Banks harmless from
     any loss or expense which Banks may sustain or incur as a consequence of
     (a) the making by Borrower of a prepayment (whether mandatory or optional)
     or any other payment of a LIBO Rate Advance on a day which is not the last
     day of the Interest Period with respect thereto, and/or (b) the conversion,
     whether voluntary or involuntary, of a LIBO Rate Advance into a Prime Rate
     Advance pursuant to this Section 3.6 or otherwise on a day which is not the
     last day of an Interest Period with respect thereto, including, without
     limitation, in each case any such loss or expense arising from the
     reemployment of funds obtained by it to maintain its LIBO Rate Advances
     hereunder or from fees payable to terminate the deposits from which such
     funds were obtained.  This covenant shall survive the termination of this
     Agreement and the payment of the Advances and all other obligations
     hereunder.

      Section 4.    Payments, Prepayments, and Reduction or Termination of the
                    Revolving Credit Facility.

      4.1 Method of Payment.  All payments of principal, interest and other
amounts to be made by Borrower under this Agreement or any of the Notes or other
Loan Documents shall be made to Agent for the account of Banks at Agent's office
at 201 St. Charles Avenue, New Orleans, Louisiana 70170 (or at such other
address as Agent or either of Banks may notify Borrower in writing), in
immediately available funds, without setoff, deduction or counterclaim, not
later than 2:00 p.m. (New Orleans, Louisiana time) on the date on which such
payment shall become due (each such payment made after such time on such due
date to be deemed to have been made on the next succeeding Business Day) and, in
the case of payments of principal under the Revolving Credit Facility, in an
amount of at least $100,000.00, or an integral multiple thereof.  Borrower
shall, at the time of making each such payment, specify to Agent the sums
payable by Borrower under this Agreement, the Notes or other Loan Documents to
which such payment is to be applied. Notwithstanding the foregoing sentence,
unless and until an Event of Default shall have occurred and be continuing (in
which event such payments shall be applied by Agent as Banks in their sole
discretion shall determine), all payments received by Agent shall be applied
first to the payment of all amounts (except principal and interest) at the time
due and unpaid hereunder or under any of the other Loan Documents, then to
interest hereon or thereon accrued to the date of payment and finally to the
unpaid principal hereunder or thereunder.  Whenever any payment under this
Agreement, the Notes or any other Loan Document shall be stated to be due on a
day that is not a Business Day, such payment may be made on the next succeeding
Business Day, and such extension of time shall in such case be included in the
computation of the payment of interest.  Upon receipt of each such payment,

                                       12
<PAGE>
 
Agent shall make prompt payment within three (3) Business Days to each Bank in
like funds of all amounts received by Agent for the account of such Bank.

      4.2 Sharing of Payments.  Banks shall share equally all payments made
pursuant to this Agreement and the benefits of and from the Collateral and all
proceeds from the sale thereof.  If either Bank shall receive at any time any
payment hereunder, or interest thereon, or receive any Collateral (or proceeds
thereof) in respect thereof (whether voluntarily or involuntarily, by setoff or
otherwise), or interest in any of the foregoing, in a greater proportion than
the other Bank (such Bank receiving the greater proportion being referred to
herein as the "Benefitted Bank"), such Benefitted Bank shall purchase for cash
from the other Bank such portion of such other Bank's Notes or Letters of
Credit, or shall provide such other Bank with the benefit of any such Collateral
or the proceeds thereof, as the case may be, as shall be necessary to cause such
Benefitted Bank to share the excess payment or benefits of such Collateral or
proceeds equally with the other Bank; provided, however, that if all or any
portion of such excess payment or benefits is thereafter recovered from such
Benefitted Bank, such purchases shall be rescinded, and the purchase price and
benefits returned, to the extent of such recovery.  Borrower agrees that each
Bank so purchasing a portion of another Bank's Notes or Letters of Credit, as
the case may be, may exercise all rights of payment (including, without
limitation, rights of setoff) with respect to such portion as fully as if such
Bank were the direct holder of such portion.

      4.3 Payments Without Deduction.  Borrower shall pay principal, interest
and other amounts under, and in accordance with the terms of, this Agreement,
the Notes and the other Loan Documents free and clear of and without deduction
for any and all present and future taxes, levies, imposts, deductions, charges,
withholdings and all other liabilities whatsoever.

                                       13

      4.4 Reduction of Credit.  Subject to Section 3.6(i) above, Borrower may
from time to time, upon at least three (3) Business Day's prior telephonic
notice (confirmed in writing) to Agent, permanently reduce the amount of the
maximum  Revolving Commitment available under the Revolving Credit Facility, but
only upon payment of the outstanding principal amount of each Note in excess of
one-half ( 1/2) of the then reduced amount of the maximum Revolving Commitment
available under the Revolving Credit Facility.  Any such reduction of the
Revolving Commitment shall be in an amount of $100,000.00 or an integral
multiple thereof.  Subject to Section 3.6(i) above, Borrower may at any time on
like notice terminate the entire Revolving Commitment available under the
Revolving Credit Facility upon payment in full of the Notes and other
liabilities of Borrower relating to the Revolving Credit Facility.

      Section 5.    Representations and Warranties of Borrower.

      Borrower represents and warrants to Banks and Agent that:

      5.1 Corporate Existence.  Each of Borrower and its Subsidiaries is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Louisiana; and each of Borrower and its Subsidiaries has all
necessary corporate power and authority to acquire, own and hold the property
and all other properties it purports to own and hold and to carry on its
business as now conducted.

      5.2 Authorization; Validity.  Each of Borrower and its Subsidiaries is
and/or has been duly authorized to execute and deliver this Agreement and all
other Loan Documents to which such Borrower or Subsidiary is a party and to
perform its obligations under this Agreement and all other Loan Documents to
which such Borrower or Subsidiary is a party.  Borrower is duly authorized and
will continue to be duly authorized to borrow money hereunder.  Each of this
Agreement and the other Loan Documents to which Borrower or one of its
Subsidiaries is a party, as executed and 

                                       14
<PAGE>
 
delivered, constitutes the legal, valid and binding obligation of Borrower
and/or such Subsidiary, enforceable in accordance with the respective terms
thereof.

      5.3 No Conflicts.  The execution and delivery of the Loan Documents and
the per formance by each of Borrower and its Subsidiaries of its obligations
thereunder do not and will not conflict with any provision of law or of the
charter or by-laws of Borrower or such Subsidiary or of any agreement binding
upon Borrower or such Subsidiary, as the case may be.

      5.4 Financial Statements.  Borrower's audited financial statement as of
December 31, 1996, a copy of which has been furnished to Banks, has been
prepared in conformity with GAAP applied on a basis consistent with that of the
preceding fiscal year and period, presents fairly the financial condition of
Borrower as of such date and the results of its operations for the periods then
ended.  Borrower's unaudited financial statement as of March 31, 1997, a copy of
which has been previously furnished to Banks, except for the absence of
footnotes normally associated with financial statements prepared in accordance
with GAAP, has been prepared in conformity with GAAP and presents fairly the
financial condition of Borrower as of such date and the results of its
operations for the periods then ended.  Since December 31, 1996, there has been
no material adverse change in Borrower's financial condition.  Since December
31, 1996, there has been no material adverse change in the financial condition
of any of Borrower's Subsidiaries.

      5.5 Litigation.  To the best of Borrower's knowledge, after due inquiry,
no litigation or governmental proceedings are pending or threatened against
Borrower or any of its Subsidiaries, the results of which might materially
affect Borrower's or such Subsidiary's  financial condition or operations,
except those referred to in a schedule furnished contemporaneously herewith and
attached hereto as Schedule 1.  Other than any liability incident to such
litigation or proceedings or provided for or disclosed in the financial
statements referred to in Section 5.4, Borrower does not 

                                       15
<PAGE>
 
have any material contingent liabilities. No Subsidiary has any material
contingent liability other than those imposed by the Collateral Documents.

      5.6 Liens.  None of the assets of Borrower or any of its Subsidiaries with
a net book value of greater than $25,000.00 is subject to any Lien, except for
the Liens created pursuant to the Collateral Documents and Permitted Liens.

      5.7 Subsidiaries.  Borrower has no Subsidiaries other than Dolphin
Services, and Dolphin Services  has no Subsidiaries.

      5.8 Purpose.  The proceeds of the Revolving Credit Facility shall be used
by Borrower for general corporate purposes.

      5.9 Use of Proceeds; Margin Securities.  Borrower is not engaged in the
business of purchasing or selling margin stock (as defined in Regulation U of
the Board of Governors of the Federal Reserve System) or extending credit to
others for the purpose of purchasing or carrying margin stock and,
notwithstanding Section 5.8 hereof, no part of the proceeds of any borrowing
hereunder will be used to purchase or carry any margin stock or for any other
purpose which would violate any of the margin regulations of such Board of
Governors.

      5.10 Compliance with ERISA.  Each of Borrower and its Subsidiaries is in
compliance with all statutes and governmental rules and regulations applicable
to it, including, without limitation, the Employee Retirement Income Security
Act of 1974, as amended ("ERISA").  No condition exists or event or transaction
has occurred in connection with any plan, as defined in Sections 3(3) and 3(37)
of ERISA, maintained by Borrower or any of its Subsidiaries (any such plan being
hereinafter called the "Plan"), which could result in Borrower's or such
Subsidiary's incurring any material liability, fine or penalty.  No Reportable
Event (as defined in ERISA) has occurred with 

                                       16
<PAGE>
 
respect to any such Plan. Neither Borrower nor any of its Subsidiaries has
withdrawn from any such Plan or initiated steps to do so and no steps have been
taken to terminate any such Plan.

      5.11 Consents.  No consent, approval or authorization of, or registration
or declaration with, any federal or state governmental authority or other
regulatory agent for the validity of the execution and delivery or for the
performance by Borrower or any of its Subsidiaries of the Loan Documents is
required.

      5.12 Tax Returns.  Each of Borrower and its Subsidiaries has filed all tax
returns which are required to be filed by any jurisdiction, and has paid all
taxes which have become due pursuant to said returns or pursuant to any
assessments.

conducted and as presently proposed to be conducted, and neither Borrower nor
any of its Subsidiaries is  in violation of any valid rights of others with
respect to any of the foregoing.

      5.14 Rights in Properties; Liens.  Each of Borrower and its Subsidiaries
has good and indefeasible title to its properties and assets, real and personal,
including the properties and assets reflected in the financial statements
described in Section 5.4 hereof, and none of the properties, assets or leasehold
interests of Borrower or any Subsidiary is subject to any Lien, except as
permitted by Section 6.11 hereof.

      5.15 Debt.  Borrower has no Debt, except as disclosed in the financial
statements described in Section 5.4 hereof and as otherwise permitted by this
Agreement.  No Subsidiary of Borrower has any Debt except as owed to Borrower or
as otherwise permitted by this Agreement.

                                       17

      5.16 Disclosure.  No statement, information, report, representation or
warranty made by Borrower or any of its Subsidiaries in this Agreement or in any
of the other Loan Documents or furnished by Borrower or any of its Subsidiaries
to Banks or Agent in connection with the negotiation or preparation of this
Agreement, or any amendment hereto, contains any untrue statement of a material
fact or omits to state any material fact necessary to make the statements herein
or therein not misleading.  There is no fact known to Borrower or to any of its
Subsidiaries that has not been disclosed in writing to Banks which has a
material adverse effect, or which might in the future have a material adverse
effect, on the business, assets, financial condition or operations of Borrower,
any of its  Subsidiaries or on the Collateral.

of Dolphin Services' business, temporarily located at job sites outside of
Terrebonne Parish). Borrower has always maintained its registered office in
either Terrebonne or East Baton Rouge Parish, Louisiana, and Dolphin Services
has always maintained its registered office in Terrebonne Parish, Louisiana.

1940, as amended.

      5.19 Other Agreements.  With the exception of construction contracts
entered into by Borrower or one of its Subsidiaries in the ordinary course of
Borrower's or such Subsidiary's business, neither Borrower nor any of its
Subsidiaries is a party to any indenture, loan or credit agreement, or to any

     thereunder.

          (b)  Environmental Matters.

          (i)   Each of Borrower and its Subsidiaries and all of their
                respective properties, assets and operations are in full

                interfere with or prevent the compliance or continued compliance
                of Borrower or any of its Subsidiaries with all Environmental

Agent to execute the Collateral Documents on behalf of each such Bank and to
take such action as Agent on such Bank's behalf, and to exercise such powers
under the Loan Documents, as are delegated to Agent by the terms thereof,
together with such other powers as are reasonably incidental thereto, including,
without limitation, the enforcement of the Loan Documents in accordance with the
terms thereof (including, without limitation, the collection of the Notes), and
Agent hereby accepts such appointment.  As to any matters not expressly provided
for by the Loan Documents (including, without limitation, enforcement or
collection of the Notes), Agent shall not be required to exercise any discretion
or take any action, but shall be required to act or to refrain from acting (and
shall be fully protected in so acting or refraining from acting) upon the
instructions of Banks and such instructions shall be binding upon Banks;
provided, however, that Agent shall not be required to take any action which
exposes Agent to personal liability or which is contrary to any of the Loan
Documents or applicable law.  Agent shall not consent to any amendment of this
Agreement or any of the other Loan Documents (and no amendment by Banks shall be
effective without consent of Agent), the effect of which would be to increase
the amount of the Obligations or extend the maturity of any obligation, reduce
the bases on which any interest is computed, release any Collateral, waive any
provision regarding covenants or obligations of Borrower or the Owners or Events
of Default, without the express written consent of all Banks.

officers, agents or employees shall be liable for any action taken or omitted to
be taken by it or them under or in

<PAGE>
 
connection with any of the Loan Documents except for its or their own gross
negligence or willful misconduct. Without limitation of the generality of the
foregoing, Agent: (i) may treat the payee of any Note as the holder thereof
until Agent receives written notice of the assignment or transfer thereof signed
by such payee and in form satisfactory to Agent; (ii) may consult with legal
counsel (including counsel for Borrower), independent public accountants and
other experts selected by it and shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants or experts; (iii) makes no warranty or representation to
any Bank and shall not be responsible to any Bank for any statements, warranties
or representations made in or in connection with any of the Loan Documents; (iv)
shall not have any duty to ascertain or to inquire as to the performance or
observance of any of the terms, covenants or conditions of any of the Loan
Documents on the part of Borrower or to inspect the property (including the
books and records) of Borrower; (v) shall not be responsible to any Bank for the
due execution, legality, validity, enforceability, genuineness, sufficiency or
value of any of the Loan Documents or any other instruments or document
furnished pursuant hereto; and (vi) shall incur no liability under or in respect
of any of the Loan Documents by acting upon any notice, consent, certificate or
other instrument or writing (which may be by telegram, cable or telex) believed
by it to be genuine and signed by the proper party or parties.

     10.3 First NBC and Affiliates.  With respect to the Note payable to the
order of First NBC and the portion of the Revolving Commitment applicable to
First NBC, First NBC shall have the same rights and powers under the Loan
Documents as the other Bank and may exercise the same as though it were not
Agent; and the term "Bank" or "Banks" shall, unless otherwise expressly
indicated, include First NBC in its individual capacity.  Without limiting the
generality of the foregoing, First NBC and its affiliates may accept deposits
from, and generally engage in any kind 

                                       37
<PAGE>
 
of business with, Borrower, and any person, firm or corporation who may do
business with or own securities of Borrower, all as if First NBC were not Agent
and without any duty to account therefor to Banks.

     10.4 Bank Credit Decision.  Each Bank acknowledges that it has,
independently and without reliance upon Agent or any other Bank and based on the
financial statements furnished by Borrower and such other documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement.  Each Bank also acknowledges that it
will, independently and without reliance upon Agent or any other Bank and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
the Loan Documents.  Each Bank acknowledges that a copy of this Agreement has
been made available to it and each Bank acknowledges that it is satisfied with
the form and substance of this Agreement.

     10.5 Indemnification.  Banks agree to indemnify and hold Agent harmless (to
the extent not reimbursed by Borrower), ratably according to the respective
principal amounts of the Notes then held by each of them (or if no Notes are at
the time outstanding, ratably according to the respective amounts of their
commitments hereunder), from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by, or asserted against Agent in any way relating to or arising out of any of
the Loan Documents or any action taken or omitted by Agent under any of the Loan
Documents (including, without limitation, attorneys' fees and other costs
associated with defending Agent against any of the foregoing), provided that no
Bank shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from Agent's gross negligence or wilful misconduct. 

                                       38
<PAGE>
 
Without limitation of the foregoing, each Bank agrees to reimburse Agent
promptly upon demand for its ratable share of any out-of-pocket expenses
(including attorneys' fees) incurred by Agent in connection with the
preparation, execution, administration, or enforcement of, or the preservation
of any rights under, the Loan Documents, to the extent that Agent is not
reimbursed for such expenses by Borrower.

     10.6 Successor Agent.  Agent may resign at any time by giving written
notice thereof to Banks and Borrower and may be removed at any time with or
without cause by Banks by notice to Borrower.  Upon any such resignation or
removal, Banks shall have the right to appoint a successor agent by notice to
Borrower.  If no successor agent shall have been so appointed by Banks, and
shall have accepted such appointment, within thirty (30) days after Agent's
giving of notice of its resignation, then Agent may, on behalf of Banks, appoint
a successor agent, by notice to Borrower and Banks, which successor agent shall
be a commercial bank organized under the laws of the United States of America or
any state thereof having a combined capital and surplus of at least $5,000,000.
Upon the acceptance of any appointment as Agent by a successor agent, such
successor agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of Agent, and Agent shall be discharged
from its duties and obligations under the Loan Documents. After Agent's
resignation or removal hereunder as Agent, the provisions of this Section 10
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Agent under the Loan Documents.

     10.7 Benefits of Section.  None of the provisions of this Section shall
inure to the benefit of Borrower or any Person other than Banks; consequently,
neither Borrower nor any other Person shall be entitled to rely upon, or to
raise as a defense, in any manner whatsoever, the failure of any Bank to comply
with such provisions.

                               FOR THE GRANT OF
                     NON-QUALIFIED STOCK OPTIONS UNDER THE
                         GULF ISLAND FABRICATION, INC.
                           LONG-TERM INCENTIVE PLAN


     THIS AGREEMENT is entered into and effective as of ________________, by and
between Gulf Island Fabrication, Inc., a Louisiana corporation (the "Company"),
and ____________ (the "Optionee").

     WHEREAS Optionee is a key employee of the Company and the Company considers
it desirable and in its best interest that Optionee be given an inducement to
acquire a proprietary interest in the Company and an incentive to advance the
interests of the Company by possessing an option to purchase shares of the
common stock of the Company, no par value per share (the "Common Stock") in
accordance with the Gulf Island Fabrication, Inc. Long-Term Incentive Plan (the
"Plan").

     NOW, THEREFORE, in consideration of the premises, it is agreed by and
between the parties as follows:

                                       I.

                                Grant of Option

     The Company hereby grants to Optionee effective as of the date hereof (the
"Date of Grant") the right, privilege and option to purchase ________ shares of
Common Stock (the "Option") at an exercise price of $________ per share (the
"Exercise Price").  The Option shall be exercisable at the time specified in
Section II below.  The Option is a non-qualified stock option and shall not be
treated as an incentive stock option under Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code").

                                      II.

                                Time of Exercise

     2.1  Subject to the provisions of the Plan and the other provisions of this
Section II, the Option shall become exercisable as to one-fifth of the shares
covered thereby on the first anniversary of the Date of Grant, an additional
one-fifth of the shares covered thereby on the second anniversary of the Date of
Grant, an additional one-fifth of the shares covered thereby on the third
anniversary of the Date of Grant, an additional one-fifth of the shares covered
thereby on the fourth anniversary of the Date of Grant, and an additional one-
fifth of the shares covered thereby on the fifth anniversary of the Date of
Grant.

                                      -1-
<PAGE>
 
     2.2  During Optionee's lifetime, the Option may be exercised only by him or
his guardian if he has been declared incompetent.  In the event of death, the
Option may be exercised as provided herein by the Optionee's estate or by the
person to whom such right devolves as a result of the Optionee's death.

     2.3  If an Optionee ceases to be an employee because of death, disability
within the meaning of Section 22(e)(3) of the Code ("Disability") or retirement,
the Option must be exercised, to the extent otherwise exercisable at the time of
termination of employment, within one year from the date on which the Optionee
ceases to be an employee, but in no event later than ten years following the
Date of Grant.

     2.4  If Optionee's employment is terminated, other than as a result of
death, disability or retirement, the Option shall terminate immediately.

     2.5  The Option shall expire and may not be exercised later than ten years
following the Date of Grant.

                                     III.

                         Method of Exercise of Option

     3.1  Optionee may exercise all or a portion of the Option by delivering to
the Company a signed written notice of his intention to exercise the Option,
specifying therein the number of shares to be purchased.  Upon receiving such
notice, and after the Company has received full payment of the Exercise Price,
the appropriate officer of the Company shall cause the transfer of title of the
shares purchased to Optionee on the Company's stock records and cause to be
issued to Optionee a stock certificate for the number of shares being acquired.
Optionee shall not have any rights as a shareholder until the stock certificate
is issued to him.

     3.2  The Option may be exercised by the payment of the Exercise Price in
cash, in shares of Common Stock held for six months or in a combination of cash
and shares of Common Stock held for six months.  The Optionee may also pay the
Exercise Price by delivering a properly executed exercise notice together with
irrevocable instructions to a broker approved by the Compensation Committee
(with a copy to the Company) to promptly deliver to the Company the amount of
sale or loan proceeds to pay the Exercise Price.

                                      IV.

                      No Contract of Employment Intended

     Nothing in this Agreement shall confer upon Optionee any right to continue
in the employment of the Company or any of its subsidiaries, or to interfere in
any way with the right of 

                                      -2-
<PAGE>
 
the Company or any of its subsidiaries to terminate Optionee's employment
relationship with the Company or any of its subsidiaries at any time.


                                       V.

                                 Binding Effect

     This Agreement shall inure to the benefit of and be binding upon the
parties hereto and their respective heirs, executors, administrators and
successors.

                                      VI.

                              Non-Transferability

     The Option granted hereby may not be transferred, assigned, pledged or
hypothecated in any manner, by operation of law or otherwise, other than by
will, by the laws of descent and distribution or pursuant to a domestic
relations order, as defined in the Code, and shall not be subject to execution,
attachment or similar process.

                                      VII.

                            Inconsistent Provisions

     The Option granted hereby is subject to the provisions of the Plan as in
effect on the date hereof and as it may be amended.  In the event any provision
of this Agreement conflicts with such a provision of the Plan, the Plan
provision shall control.

                       REPORT OF INDEPENDENT ACCOUNTANTS



To the Board of Directors and Shareholders of
Gulf Island Fabrication, Inc.


In our opinion, the accompanying balance sheet and the related statements of
income, of changes in shareholders' equity and of cash flows present fairly, in
all material respects, the financial position of Gulf Island Fabrication, Inc.
(the "Company") at December 31, 1995 and 1996, and the results of its operations
and its cash flows for each of the two years in the period ended December 31,
1996, in conformity with generally accepted accounting principles.  These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits.  We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.
