     This prospectus contains forward-looking statements. All statements other
than statements of historical facts contained in this prospectus, including
statements regarding our future financial position, business strategy, budgets,
projected costs and plans and objectives of management for future operations,
are forward-looking statements. Although we believe our expectations reflected

cannot assure you that these expectations will prove to have been correct.
Risks, uncertainties and assumptions that could cause actual results to differ
materially from the expectations reflected in the forward-looking statements
include, among other things:

     - the demand for our products and services is cyclical and vulnerable to
       changes in the economy;

     - the dollar amount of our backlog, as stated at any given time, is not
       necessarily indicative of our future earnings;

     - political and economic conditions in countries in which we operate could
       adversely affect us; and

     - our projects expose us to potential product liability and warranty
       claims.

     We undertake no obligation to update or revise our forward-looking
statements, whether as a result of new information, future events or otherwise.

                               PROSPECTUS SUMMARY

     You should read the following summary together with the more detailed
information and financial statements and notes appearing elsewhere in this
prospectus before making an investment decision. The terms "Shaw," "we," "us"
and "our" as used in this prospectus refer to The Shaw Group Inc., including our
subsidiaries. Unless we indicate otherwise, all information in this prospectus
assumes no exercise of the over-allotment option granted to the underwriters by
us.

THE SHAW GROUP INC.

     We are the largest supplier of fabricated piping systems in the United
States and one of the leading suppliers of integrated piping systems and
services for new construction, site expansion and retrofit projects in the
world. We are a cost-effective, single-source provider of fabricated piping
systems and services for projects primarily in the following industries:

     - power generation;
     - chemical processing;
     - crude oil refining;
     - petrochemical processing; and
     - oil and gas exploration and production.

     By serving a diverse portfolio of industries worldwide, we reduce our
dependence on any one industry or geographic region. We are currently
benefitting from substantial demand for our products and services in the power
generation industry, particularly for activity related to the installation of
gas turbine power systems in the United States. We believe that we have provided
more piping systems for the power generation market worldwide than any other
domestic competitor, positioning us to capitalize on the significant and growing
demand in this sector.

     We differentiate ourselves from our competition by offering our customers
comprehensive piping solutions consisting of integrated engineering, design,
fabrication, erection and maintenance of piping systems and the manufacture of
pipe fittings. Over the past several years, our customers have included:

<TABLE>
<S>                                     <C>
AlliedSignal, Inc.                      Mitsubishi Heavy Industries, Inc.
Black & Veatch Corporation              Monsanto
Chevron Chemical                        Raytheon Engineers & Constructors,
Duke/Fluor Daniel                       Inc.
FMC Corporation                         Rolls Royce
Hitachi                                 Southern Companies Service, Inc.
                                        Toshiba Corporation
</TABLE>

     We have also formed strategic alliances with:

<TABLE>
<S>                                     <C>
ABB AG                                  The Dow Chemical Company
Air Products and Chemicals, Inc.        General Electric Company
Alstom S.A.                             Orion Refining Corporation
BASF AG                                 Parsons Corporation
Bechtel Corporation                     Praxair, Inc.
</TABLE>

     We were founded in 1987 and have expanded rapidly through internal growth
and the completion and integration of a series of strategic acquisitions. We
have increased our revenues from $131.1 million for fiscal 1994 to $494.0
million for fiscal 1999, representing a 30% compound annual growth rate. Over
this same time period, we have also achieved a 30% compound annual growth rate
in earnings per share. In addition, our backlog has increased from $75.0 million
as of August 31, 1994 to $818.3 million as of August 31, 1999.

OUR COMPETITIVE ADVANTAGES

     Over the past several years, we have increased our pipe fabrication
capacity, expanded our products and services, and broadened the scope of our
projects to include engineering, pipe erection, maintenance and related
construction services. These initiatives have enabled us to become a
technologically advanced producer of complex piping systems, to achieve
substantial economies of scale in purchasing raw materials and to provide our
customers with a broad range of products and services. As a result, we benefit
from the following competitive advantages:

          Coordination and integration of piping systems and services. Our
     ability to provide our customers with a single source of comprehensive
     piping products and services and to coordinate and integrate our products
     and services allows us to maximize project efficiency and reduce lead time
     and costs for our customers.

          State-of-the-art induction pipe bending technology. We believe that we
     offer our customers the most sophisticated and efficient induction pipe
     bending machines and technology available in the world today. Induction
     bending is a technique using simultaneous super-heating and compression of
     pipe to produce tight-radius bends to our customers' specifications. When
     compared to the traditional cut and weld method, our technology provides a
     more uniform and cost-effective product that is generally considered to be
     stronger and less prone to structural fatigue.

          Established, diversified customer base. Our customers include a group
     of large, multi-national companies with whom we have long-standing
     relationships. Because many of our customers are active in more than one of
     the industries we serve, they have historically remained significant
     purchasers of our piping systems and services despite fluctuations in
     activity within any particular industry.

          Strategically positioned worldwide operations. We have established a
     leading market position in the United States and have devoted substantial
     resources to select international markets in South America, Europe, Asia
     and Australia. We believe that our international presence strengthens our
     ability to pursue new markets and customers on a global basis, particularly
     multi-national customers seeking suppliers who can provide worldwide
     solutions for their piping requirements.

          Proprietary software technology. Our proprietary SHAW-DRAW(TM) and
     SHAW-MAN(TM) software programs enhance our customers' ability to plan,
     schedule and track their projects and reduce installation costs and cycle
     times. Many of our customers have found our software to be of such value
     that they have electronically linked their own planning and control
     processes with our systems and software.

          Specialty manufacturing capability. While our competitors are
     generally dependent on third-party manufacturers of specialty fittings, we
     have the capability to manufacture many of these products in-house. By
     manufacturing these critical elements of the pipe fabrication process, we
     are able to maintain greater control over the sourcing of fittings, which
     reduces our supply costs and minimizes delays in fabrication.

OUR BUSINESS STRATEGY

     Our business strategy is to enhance our leading position as a provider of
comprehensive piping solutions within existing markets and to enter select new
markets. We intend to achieve this goal by:

          Growing through internal development. Our fabrication facilities are
     currently operating at or near capacity while our backlog has more than
     tripled in the last year. In order to meet projected demand, we anticipate
     developing or acquiring one or more facilities in the next year. We will
     also evaluate opportunities to enter new international markets,
     particularly those in which significant power plant construction is
     anticipated.

          Pursuing alliance agreements. We intend to enter into additional
     alliance agreements with current and future customers. Our alliance
     agreements enhance our ability to obtain contracts for individual projects
     by eliminating formal bid preparation. These agreements have tended to
     provide us
                                        2
<PAGE>   6

     with a steady source of projects, minimize the impact of short-term pricing
     volatility and enable us to anticipate a larger portion of our future
     revenues.

          Strengthening our technological position. We will continue to
     strengthen our technological position through investment in new equipment,
     technology and information systems, which we believe will allow us to
     increase our fabrication and manufacturing capabilities and capacity,
     better integrate our product and service offerings and improve overall
     project efficiency.

          Expanding our erection, maintenance and related construction
     services. We have developed expertise in providing erection, maintenance
     and construction services related to our core fabrication projects. We
     believe that our ability to offer these services appeals to many of our
     customers and provides us with significant growth opportunities.

          Pursuing selective acquisitions. Since October 1996 we have completed
     11 acquisitions for total consideration of approximately $93 million. We
     intend to continue to pursue selective acquisitions of businesses that will
     expand or complement our current portfolio of products and services.

     We are a Louisiana corporation. Our principal executive offices are located
at 8545 United Plaza Boulevard, Baton Rouge, Louisiana 70809, and our telephone
number is (225)932-2500.

                                  RISK FACTORS

     Investing in our common stock will provide you with an equity ownership
interest in us. As our shareholder, you will be subject to risks inherent in our
business. The performance of your shares will reflect the performance of our
business relative to, among other things, general economic and industry
conditions, market conditions and competition. The value of your investment may
increase or decline and could result in a loss. You should carefully consider
the following factors as well as other information contained in this prospectus
before deciding to invest in shares of our common stock.

     This prospectus also contains forward-looking statements that involve risks
and uncertainties. Our actual results could differ materially from those
anticipated in the forward-looking statements as a result of many factors,
including the risk factors described below and the other factors described
elsewhere in this prospectus. See "Forward-Looking Statements."

DEMAND FOR OUR PRODUCTS AND SERVICES IS CYCLICAL AND VULNERABLE TO CHANGES IN
THE ECONOMY.

     The demand for our products and services depends primarily on the existence
of erection and retrofit projects, particularly in the power generation,
chemical processing, crude oil refining and petrochemical processing industries.
These industries historically have been, and will likely continue to be,
cyclical in nature and vulnerable to general downturns in the economy. Our
results of operations have varied and may continue to vary depending on the
demand for future projects from these industries. For example, demand in the
petrochemical processing sector has declined significantly in recent periods.

THE DOLLAR AMOUNT OF OUR BACKLOG, AS STATED AT ANY GIVEN TIME, IS NOT
NECESSARILY INDICATIVE OF OUR FUTURE EARNINGS.

     We cannot assure you that the revenues projected in our backlog will be
realized. To the extent that we experience significant terminations or
adjustments in the scope of our projects as reflected in our backlog contracts,
we could be materially adversely affected.

     We define our backlog as a "working backlog," which includes projects for
which we have received a commitment from our customers. This commitment takes
the form of a written contract for a specific project, a purchase order or a
specific indication of the amount of time or material we need to make available
for a customer's anticipated project. In certain instances the engagement is for
a particular product or project for which we estimate anticipated revenue, often
based on engineering and design specifications that have not been finalized and
may be revised over time. Our backlog for maintenance work is derived from
maintenance contracts and our customers' historic maintenance requirements.

     Approximately $300 million, or 37%, of our backlog at August 31, 1999 is
attributable to a contract with General Electric that requires us to fabricate
90% of the pipe necessary to install the combined-cycle gas turbines to be built
by General Electric domestically through 2004. Approximately 53% of this backlog
is for power generation projects for which General Electric has been engaged and
is in various stages of design, engineering and construction, and for which we
have received a work release or have been notified that a work release is
pending. The balance is for work for which General Electric has requested that
we reserve capacity. We cannot assure you that all of these projects will be
constructed or that they will be completed in our currently anticipated
time-frame.

     On occasion, customers will cancel or delay projects for reasons beyond our
control. In the event of project cancellation, we may be reimbursed for certain
costs but typically have no contractual right to the total revenues reflected in
our backlog. In addition, projects may remain in our backlog for extended
periods of time. If we were to experience significant cancellations or delays of
our projects in backlog, our financial condition would be significantly
adversely affected.

OUR RESULTS OF OPERATIONS DEPEND ON OUR ABILITY TO OBTAIN FUTURE CONTRACTS.

     In the case of large-scale domestic and international projects where timing
is often uncertain, it is particularly difficult to predict whether and when we
will receive a contract award. The uncertainty of our
                                        7
<PAGE>   11

contract award timing can present difficulties in matching workforce size with
contract needs. In some cases, we maintain and bear the cost of a ready
workforce that is larger than called for under existing contracts in
anticipation of future workforce needs under expected contract awards. If an
expected contract award is delayed or not received, we would incur costs that
could have a material adverse effect on us.

     Projects in the power generation, chemical processing, crude oil refining
and petrochemical processing industries frequently involve a lengthy and complex
bidding and selection process. Because a significant portion of our sales is
generated from large projects, our results of operations can fluctuate from
quarter to quarter. While our revenues are derived from a concentrated customer
base, our significant customers vary between years. The loss of any one or more
of our key customers could have a material adverse impact on us.

POLITICAL AND ECONOMIC CONDITIONS IN COUNTRIES IN WHICH WE OPERATE COULD
ADVERSELY AFFECT US.

     In fiscal 1999, approximately 26% of our sales was attributable to projects
in international markets. We expect international sales and operations to
continue to contribute materially to our growth and earnings for the foreseeable
future. International contracts, operations and expansion expose us to risks
inherent in doing business outside the United States, including:

     - uncertain economic conditions in the foreign countries in which we make
       capital investments, operate and sell products and services;

     - the lack of well-developed legal systems in some countries in which we
       operate and sell products and services, which could make it difficult for
       us to enforce our contractual rights;

     - expropriation of property;

     - restrictions on the right to convert or repatriate currency; and

     - political risks, including risks of loss due to civil strife, acts of
       war, guerrilla activities and insurrection.

     The risks associated with operating internationally are reflected in the
recent decrease in our international sales from $215.1 million in fiscal 1998 to
$127.8 million in fiscal 1999. The decrease was primarily attributable to the
economic downturn in the Far East/Pacific Rim, resulting in fewer power
generation projects, and general economic conditions and political events in
South America, causing a reduction in sales to the petrochemical processing
sector.

FOREIGN EXCHANGE RISKS MAY AFFECT OUR ABILITY TO REALIZE A PROFIT FROM CERTAIN
PROJECTS.

     While we attempt to denominate our contracts in United States dollars, from
time to time we enter into contracts denominated in a foreign currency without
escalation provisions. This practice subjects us to foreign exchange risks.
Foreign exchange controls may also adversely affect us. For instance, prior to
the lifting of foreign exchange controls in Venezuela in November 1995, these
controls adversely affected our ability to repatriate profits from our
Venezuelan subsidiary or otherwise convert local currency into United States
dollars. We generally do not obtain insurance for or hedge against foreign
exchange risks. In addition, our ability to obtain international contracts is
impacted by the relative strength or weakness of the United States dollar
relative to foreign currencies.

THE NATURE OF OUR CONTRACTS COULD ADVERSELY AFFECT US.

     We enter into fixed price or lump-sum contracts on a significant number of
our domestic contracts and substantially all of our international projects. Our
profit for the projects could decrease, or we could experience losses, if we are
unable to secure fixed pricing commitments from our suppliers at the time the
contracts are entered into or if we experience cost increases for material or
labor during the performance of the contracts.

                                        8
<PAGE>   12

     We enter into contractual agreements with customers for some construction
services to be performed based on agreed upon reimbursable costs and labor
rates. In some instances, the terms of these contracts provide for the
customer's review of the accounting and cost control systems to verify the
completeness and accuracy of the reimbursable costs invoiced. These reviews
could result in proposed reductions in reimbursable costs and labor rates
previously billed to the customer.

OUR DEPENDENCE ON A FEW SPECIALIZED SUPPLIERS FOR SOME OF OUR MATERIALS COULD
ADVERSELY AFFECT US.

     Our principal raw materials are carbon steel, stainless steel and other
alloy piping, which we obtain from a number of domestic and foreign primary
steel producers. To the extent that we cannot acquire raw materials, our ability
to complete a project in a timely fashion or at a profit may be jeopardized. In
addition, if a manufacturer is unable to deliver the materials according to the
negotiated terms, we may be required to purchase the materials from another
source at a higher price. This may reduce the profit to be realized or result in
a loss on a project for which the materials were needed.

OUR PROJECTS EXPOSE US TO POTENTIAL PRODUCT LIABILITY, WARRANTY CLAIMS AND
LIABILITY CLAIMS ARISING FROM OUR CONSTRUCTION PROJECTS.

     Our products are typically installed in large industrial facilities in
which system failure can be disastrous. Any catastrophic occurrences in excess
of insurance limits at locations where our products are installed could result
in significant product liability or warranty claims against us. In addition,
under some of our contracts, we must use new metals or processes for producing
or fabricating pipe for our customers. The failure of any of these metals or
processes could result in warranty claims against us for significant replacement
or reworking costs.

     The increasing number of erection and construction projects we are
performing exposes us to additional risk including cost overruns, equipment
failures, personal injuries, property damage, shortages of materials and labor,
work stoppages, labor disputes, weather problems and unforeseen engineering,
architectural, environmental and geological problems. In addition, once our
construction is complete, we may face claims with respect to the performance of
these facilities.

PROBLEMS INTEGRATING ACQUISITIONS AND MANAGING OUR GROWTH COULD ADVERSELY AFFECT
US.

     We have experienced substantial growth through internal expansion and
acquisitions, and we plan to pursue select acquisitions in the future. Because
we pursue acquisitions around the world and may actively pursue a number of
opportunities simultaneously, we may encounter unforeseen expenses,
complications and delays, including difficulties in staffing and providing
operational and management oversight. As we expand our operations through
acquisitions, we may encounter difficulties integrating acquisitions and
successfully managing our growth. We cannot assure you that our current
management, personnel and other corporate infrastructure will be adequate to
manage our growth or that our systems, procedures and controls will be adequate
to support our expanding operations. To the extent we encounter problems in
integrating acquisitions and managing our growth, we could be materially
adversely affected.

     We are currently operating at or near full capacity in all of our operating
facilities. Our production needs will likely exceed our current capacity in the
future. To satisfy our production needs, we plan to purchase or build additional
plants. We cannot assure you that we will complete the acquisition or
construction of these plants on a timely basis or at our budgeted costs.

OUR COMPETITORS MAY HAVE GREATER RESOURCES AND EXPERIENCE THAN WE DO.

     In pipe engineering and fabrication, we experience significant competition
from competitors in both international and domestic markets. In the United
States, there are a number of smaller pipe fabricators. Internationally, our
principal competitors are divisions of large industrial firms. Some of our
competitors, primarily in the international sector, have greater financial and
other resources than we do.

                                        9
<PAGE>   13

     In our erection, maintenance and related construction services, we have
numerous regional, national and international competitors, many of which have
greater financial and other resources than we do. Moreover, we are a recent
entrant into this business, and many of our competitors also possess
substantially greater experience, market knowledge and customer relationships
than we do.

ENVIRONMENTAL FACTORS AND CHANGES IN LAWS AND REGULATIONS COULD INCREASE OUR
COSTS AND LIABILITIES.

     We are subject to environmental laws and regulations, including those
concerning:

     - emissions into the air;
     - discharges into waterways;
     - generation, storage, handling, treatment and disposal of waste materials;
       and
     - health and safety.

     These laws and regulations generally impose limitations and standards for
certain pollutants or waste materials and require us to obtain a permit and
comply with various other requirements. Governmental authorities may seek to
impose fines and penalties on us, or revoke or deny the issuance or renewal of
operating permits, for failure to comply with applicable laws and regulations.

     In addition, under the Comprehensive Environmental Response, Compensation
and Liability Act of 1980 and comparable state laws, we may be required to
investigate and remediate hazardous substances. CERCLA and these comparable
state laws typically impose liability without regard to whether a company knew
of or caused the release, and liability has been interpreted to be joint and
several unless the harm is divisible and there is a reasonable basis of
allocation. Our foreign operations are also subject to various requirements
governing environmental protection.

     The environmental health and safety laws and regulations to which we are
subject are constantly changing, and it is impossible to predict the effect of
such laws and regulations on us in the future. We have not conducted
environmental audits of all of our properties. We cannot assure you that our
operations will continue to comply with future laws and regulations or that
these laws and regulations will not significantly adversely affect us.

WORK STOPPAGES AND OTHER LABOR PROBLEMS COULD ADVERSELY AFFECT US.

     Some of our employees in the United States are represented by a union. We
experienced a strike, without material impact on production, by union members in
February 1997 relating to the termination of collective bargaining agreements
covering our facilities in Walker and Prairieville, Louisiana. A lengthy strike
or other work stoppage at any of our facilities could have a material adverse
effect on us. From time to time we have also experienced attempts to unionize
our non-union shops. While these efforts have achieved limited success to date,
we cannot assure you that we will not experience additional union activity in
the future.

PROTECTION OF OUR INDUCTION PIPE BENDING AND SOFTWARE TECHNOLOGY IS LIMITED AND
OUR COMPETITORS MAY DEVELOP OR OTHERWISE ACQUIRE EQUIVALENT OR SUPERIOR
TECHNOLOGY.

     Our induction pipe bending technology and capabilities impact our ability
to compete successfully. This technology and our proprietary software are not
currently patented. While we may have some legal protections, litigation brought
by us in this regard could be time-consuming and expensive and could prove
unsuccessful. Likewise, although we protect some proprietary materials and
processes through non-disclosure and confidentiality agreements, we cannot
assure you that these agreements will not be breached. Finally, there is nothing
to prevent our competitors from independently attempting to develop or obtain
access to technologies that are similar or superior to our technology.

                                       10
<PAGE>   14

OUR SUCCESS DEPENDS ON KEY MEMBERS OF OUR MANAGEMENT, INCLUDING J.M. BERNHARD,
JR.

     Our success is dependent upon the continued services of J. M. Bernhard,
Jr., our founder, Chairman, President and Chief Executive Officer, and other key
officers. The loss of Mr. Bernhard or other key officers could adversely affect
us.

OUR ARTICLES OF INCORPORATION AND BY-LAWS AND LOUISIANA LAW CONTAIN PROVISIONS
THAT CONCENTRATE VOTING POWER IN MANAGEMENT AND COULD DISCOURAGE A TAKEOVER.

     At September 30, 1999, our officers and directors beneficially owned
approximately 25% of our outstanding common stock but, due to the voting
provisions described below, controlled in excess of 56% of the voting power.
Consequently, these persons, in particular Mr. Bernhard, will be able to
exercise significant influence over corporate actions and the outcome of matters
requiring a shareholder vote, including the election of directors. See
"Principal Shareholders" and "Description of Capital Stock."

     Our articles of incorporation provide that each share of common stock that
has been held by the same person for at least four consecutive years is entitled
to five votes on each matter to be voted upon at shareholders' meetings, and all
shares held for less than four years are entitled to one vote per share for each
matter. This charter provision concentrates control in current management and
could:

     - increase the difficulty of removing the incumbent board of directors or
       management;
     - diminish the likelihood that a potential buyer would make an offer for
       the common stock; and
     - impede a transaction favorable to the interests of some shareholders.

Each purchaser of shares of common stock offered under this prospectus will be
entitled to one vote for each share of common stock at all shareholders'
meetings until the shares have been continuously owned for a period of four
years. After the shares have been continuously owned by the same person for a
period of four years, the holder will be entitled to five votes for each share
on all matters submitted to shareholders. See "Description of Capital
Stock -- Common Stock."

     In addition, certain provisions of our articles of incorporation and
by-laws and Louisiana law may tend to deter potential unsolicited offers or
other efforts to obtain control of us that are not approved by our board of
directors. The provisions may deprive our shareholders of opportunities to sell
shares of common stock at prices higher than prevailing market prices. See
"Description of Capital Stock."

OUR ISSUANCE OF PREFERRED STOCK COULD ADVERSELY AFFECT YOUR RIGHTS AS A HOLDER
OF COMMON STOCK.

     Our board of directors is authorized to issue up to 5,000,000 shares of
preferred stock without any further action on the part of our shareholders. In
the event we issue preferred stock in the future that has preference over the
common stock with respect to payment of dividends or upon our liquidation,
dissolution or winding up, your rights as holders of common stock could be
adversely affected. See "Description of Capital Stock -- Preferred Stock."

OUR COMPUTER SYSTEMS AND THOSE OF THIRD PARTIES MAY NOT BE YEAR 2000 COMPLIANT,
WHICH MAY CAUSE SYSTEM FAILURES AND DISRUPTIONS IN OPERATIONS.

     The inability of some computer programs and embedded computer chips to
distinguish between the year 1900 and the year 2000 poses a serious threat of
business disruption to any organization that utilizes computer technology in its
business systems or equipment. If our information systems fail or if suppliers
on which we depend for essential goods and services experience information
system failures, we could be materially adversely affected. We could face
substantial claims by customers, as well as loss of revenues, due to:

     - service interruptions;
     - inability to fulfill contractual obligations;
     - inability to account for transactions; and

                                       11
<PAGE>   15

     - increased expenses associated with
          -- litigation;
          -- harm to persons or to property;
          -- stabilization of operations following system failures; and
          -- the execution of contingency plans.

     In addition:

     - we depend on third parties, including customers, suppliers and service
       providers, who may fail to address adequately their year 2000 problems;
       and

     - we rely on automated plant systems, computerized billing procedures and
       other embedded chip technologies that could necessitate expensive
       corrective actions.

     Any or all of these consequences, should they materialize, could have a
material adverse effect on us. For a more detailed discussion on the state of
our year 2000 readiness, the costs we anticipate incurring to become year 2000
ready and our year 2000 contingency plans, see "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Year 2000."

                                USE OF PROCEEDS


     We estimate that we will receive approximately $58.7 million from this
offering, after deducting the underwriting discount and estimated expenses of
the offering. If the underwriters' over-allotment option is exercised, we
estimate that we will receive an additional $8.9 million. We intend to use
approximately $47.6 million of the proceeds to repay borrowings under our
revolving credit facility and the remaining proceeds for general corporate
purposes. Following this repayment, we will have approximately $100 million of
borrowing capacity under this facility to fund capital requirements including:


     - expanding our domestic and international operating capacity;
     - increasing available working capital; and
     - financing future acquisitions.

     The amount outstanding under the revolving credit facility at September 30,
1999 was $47.6 million, bore interest at a weighted average rate of 6.53% for
fiscal 1999 and matures on May 31, 2002. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."

                                DIVIDEND POLICY

     We have not paid any dividends on the common stock and currently anticipate
that any earnings will be retained for the development of our business.
Accordingly, no dividends are expected to be declared or paid on the common
stock for the foreseeable future. The declaration of dividends is at the
discretion of our board of directors. Our dividend policy will be reviewed by
our board of directors as may be appropriate in light of relevant factors at the
time. We are, however, subject to limitations on the payment of dividends under
the terms of our revolving credit facility.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     This prospectus contains forward-looking statements regarding Shaw's
performance, strategy, plans, objectives, expectations, beliefs and intentions.
When used in this prospectus, the words "intend," "anticipate," "believe,"
"estimate," "plan" and "expect" and similar expressions as they relate to us are
included to identify forward-looking statements. Our actual results could differ
materially from the results discussed in the forward-looking statements as a
result of the risk factors set forth elsewhere in this prospectus. See
"Forward-Looking Statements" and "Risk Factors." The following discussion and
analysis should be read in conjunction with "Selected Consolidated Financial
Data" and our consolidated financial statements and the notes thereto included
elsewhere in this prospectus.

GENERAL

     We are the largest supplier of fabricated piping systems in the United
States and one of the leading providers of integrated piping systems and
services for new construction, site expansion and retrofit projects in the
world. We were founded in 1987 and have expanded rapidly through both internal
growth and a series of strategic acquisitions. Most of our operations are
conducted through wholly-owned subsidiaries, although we own a 49% interest in
Shaw-Nass, a joint venture for pipe fabrication in Bahrain. We provide our
products and services to customers in the power generation, chemical processing,
crude oil refining, petrochemical processing, oil and gas exploration and
production and other industries, including pulp and paper, food processing and
pharmaceuticals. We serve our customers on a worldwide basis and have
established a leading market position in the United States as well as select
international markets in South America, Europe, Asia and Australia.

     As discussed below, our financial performance is impacted by the broader
economic trends affecting our customers. All of the major industries in which we
operate are cyclical. Because our customers participate in a broad portfolio of
industries, our experience has been that downturns in one of our sectors may be
mitigated by opportunities in others. The domestic power generation market
currently represents our most significant growth opportunity. Despite a
softening in the international power generation market, our operating results in
the fourth quarter of fiscal 1999 show significant additional activity primarily
attributable to combined-cycle gas turbines being built by General Electric.
Because the outlook for power generation investments is strong (the Energy
Information Agency estimates that $1.4 trillion will be spent globally between
1995 and 2010), we believe that we are well positioned to capitalize on these
opportunities. While our chemical processing and crude oil refining customers
have experienced limited growth in recent years, we continue to experience
relatively steady activity in those sectors as our customers complete retrofit
and expansion work required to produce new products, modernize aging facilities
and meet increasingly stringent environmental requirements. The petrochemical
processing sector accounted for a declining percentage of our revenues in 1999
as that sector has experienced a significant downturn over the past several
years. We do not expect increased activity in this sector in the near-term.
Finally, we entered the oil and gas exploration and production sector in July
1998 and expect our activity in this sector to increase after oil and gas
companies increase capital spending based on recent increases in prices of oil
and gas.

     Due to increased demand for our services, our backlog has increased from
$75.0 million as of August 31, 1994 to $818.3 million as of August 31, 1999.
Approximately 64% of this backlog is attributable to the power generation
sector, 12% to the chemical processing sector, 19% to the crude oil refining
sector, 4% to the oil and gas exploration and production sector and 1% for other
industries. Our backlog is largely a reflection of the broader economic trends
being experienced by our customers and is important to us in anticipating our
operational needs. Backlog is not a measure defined in generally accepted
accounting principles and our backlog may not be comparable to backlog of other
companies. While we believe backlog information may be helpful in understanding
our business, it is not necessarily indicative of our future earnings. See "Risk
Factors" and "Business -- Backlog."

     Since our formation in 1987, we have experienced significant growth both
from internal expansion and the completion and integration of a series of
strategic acquisitions. While we did not complete any
                                       18
<PAGE>   22

acquisitions in fiscal 1999, from October 1996 through July 1998 we completed 11
acquisitions for aggregate consideration of approximately $93 million. As
discussed below, these acquisitions continue to have a significant impact on our
results of operations. The acquisitions reflected in the discussion of our
results of operations presented below include:

     - Pipe Shields, an industrial pipe insulation company located in
       California, purchased in October 1996;
     - NAPTech, a pipe fabricator and pipe module engineering firm located in
       Utah, purchased in January 1997;
     - United Crafts, an industrial erection and maintenance company located in
       Louisiana, purchased in February 1997;
     - MERIT Industrial Constructors, an industrial erection and maintenance
       firm located in Louisiana, purchased in March 1997;
     - Pipework Engineering and Development, a pipe fabrication company located
       in the United Kingdom, purchased in October 1997;
     - Prospect, a power piping contractor headquartered in the United Kingdom
       with operations in Australia and Virginia, purchased in November 1997;
     - Lancas, a construction company located in Venezuela, purchased in January
       1998;
     - Cojafex, a manufacturer of induction bending equipment, purchased in
       January 1998; and
     - Bagwell, an offshore fabrication and construction firm located in
       Louisiana, purchased in July 1998.

     Revenues from domestic projects increased $79.7 million, or 28%, from
$286.5 million for fiscal 1998 to $366.2 million for fiscal 1999. Increases were
experienced in all domestic industry sectors except petrochemical processing.
Revenues from international projects decreased $87.3 million, or 41%, from
$215.1 million for fiscal 1998 to $127.8 million for fiscal 1999. The decline in
international sales was primarily attributable to decreases in activity in the
power generation sector in the Far East/Pacific region, in the crude oil
refining sector in South America and the Middle East and in the chemical
processing sector in South America.

     Although our total revenues from power generation projects declined in
fiscal 1999 compared to fiscal 1998, revenues from domestic power generation
projects increased nearly 51% for fiscal 1999 compared to fiscal 1998 due to new
domestic power generation projects, including the start-up of our announced $300
million, five-year contract for General Electric in August 1999. In fiscal 1999,
we experienced a decline in international power generation project revenues,
particularly in the Far East/Pacific Rim market due to general economic
conditions. Revenues associated with international power generation projects
declined 33% in fiscal 1999 compared to fiscal 1998.

     Revenues from the chemical processing industry increased in fiscal 1999
over the prior year due to increased domestic activity offset in part by
decreased international activity. The decrease in international chemical
processing revenues was due primarily to weak activity in the South American
region as a result of general economic conditions.

     Revenues from the crude oil refining industry for fiscal 1999 increased
over the prior year due to increases in domestic project activity exceeding
declines in international project activity. Domestically, our activity was
positively impacted by a large construction project for a refinery in Norco,
Louisiana that accounted for approximately 14% of our revenues in fiscal 1999.
We experienced a decrease in revenues from international crude oil refining
primarily due to weak activity in South America (resulting from general economic
conditions and recent political events, particularly in Venezuela) and the
Middle East.

     Revenues from the petrochemical processing industry decreased significantly
in both the domestic and international markets during fiscal 1999 compared to
the prior year. The decrease in revenues from petrochemical processing was
primarily attributable to weak global demand.

     Revenues from the oil and gas exploration and production industry increased
in fiscal 1999 over fiscal 1998 due to the results of a subsidiary that we
acquired in July 1998 and were partially offset by reductions in oil and gas
project work performed by our other subsidiaries. Most of our revenues from this
sector are domestic.

     Our gross profit margin for fiscal 1999 increased to 19.0% from 15.9% for
the prior year. The gross profit margin was positively impacted by increased
revenues from higher-margin projects in the domestic power generation, chemical
processing and crude oil refining industries. The overall increase in demand for
domestic power generation related projects has had a favorable impact on margins
for those projects. We anticipate that margins on domestic power generation
projects should remain stable provided that the current level of demand for
these projects remains steady. We have historically realized lower overall
margins on our erection and construction services because we generally assume
responsibility for providing all materials and subcontractor costs on these
projects. These costs are typically passed through to the customer with minimal
profit recognized by us. During fiscal 1999, we entered into a contract for the
expansion of a refinery in Norco, Louisiana which excluded materials and
subcontractor costs from the scope of our services. We do not expect to continue
to enter into erection and construction contracts which exclude a significant
amount of customer furnished material or subcontractor costs in the future. The
increase in the gross profit margin was partially offset by continued lower
margins on our manufactured products due to pricing pressures from foreign
imports and lower margins from our foreign operations due to reduced activity in
the foreign power generation and petrochemical processing industries. During the
second half of fiscal 1999, we began to experience easing of pricing pressures
for foreign imports. As previously discussed, we do not expect to see short-term
improvements in our various foreign operating locations and anticipate margins
will remain unchanged in our foreign operating locations.

     General and administrative expenses were $60.1 million for fiscal 1999, up
24% from $48.5 million for fiscal 1998. The increase primarily related to growth
of our erection and construction services and the integration of Shaw Bagwell,
Inc., our oil and gas services subsidiary, and Shaw Lancas, C.A., our Venezuelan
construction subsidiary, into our business for all of fiscal 1999. We believe
that general and administrative expenses as a percentage of revenues will trend
downward toward historical levels as revenues from Shaw Bagwell, Inc. and Shaw
Lancas, C.A. increase, but we cannot assure you that this will occur.

     For fiscal 1999, interest expense was $8.6 million, up $0.1 million from
$8.5 million in the previous year. Interest expense varies in relation to the
balances in, and variable interest rates under, our principal revolving line of
credit facility, which has generally been used to provide working capital and
fund fixed asset purchases and subsidiary acquisitions. Additionally, during
fiscal 1999, we used our line of credit facility to purchase treasury stock
totaling $13.7 million.

     Our effective tax rates for fiscal 1998 and fiscal 1999 were 30.2% and
33.1%, respectively. The increase in our effective tax rate from fiscal 1998 to
fiscal 1999 was due to the reduced amount of foreign export sales and a reduced
amount of income earned in foreign jurisdictions with lower tax rates than the
United States Federal rate.

    FISCAL 1998 COMPARED TO FISCAL 1997

     Revenues increased 49.4% for fiscal 1998 to $501.6 million from $335.7
million for fiscal 1997. Gross profit increased 24.4% to $79.6 million for
fiscal 1998 from $64.0 million for fiscal 1997. Approximately $112 million of
the increase in revenues related to sales of subsidiaries that we acquired
during fiscal 1998.

     Revenues from domestic projects increased $54.0 million, or 23%, from
$232.5 million for fiscal 1997 to $286.5 million for fiscal 1998. Revenues in
fiscal 1998 from all geographic areas increased over fiscal 1997 levels
primarily due to our continued expansion through acquisitions. The increase in
revenues from Europe in fiscal 1998, compared to the prior year, was primarily
due to the acquisition of our United Kingdom operations (Pipework Engineering
and Development and Prospect) in the first quarter of fiscal 1998. During fiscal
1998, we began streamlining our United Kingdom operations.

*  Sales for our petrochemical processing and oil and gas exploration and
   production sectors are not segregated and are included in the other sectors
   in the above chart for fiscal 1997.

     Revenues from the power generation sector in fiscal 1998 increased over the
prior year primarily due to increased revenues from the international power
generation market. Revenues from the international power generation market
increased primarily as a result of the acquisitions of Pipework Engineering and
Development and Prospect. Domestic power generation revenues also increased
primarily due to the expansion of construction services performed by our
subsidiaries that were acquired in February and March of 1997.

     Revenues from the chemical processing sector increased slightly over fiscal
1997 as a result of increased activity in both the domestic and international
markets.

     Revenues from the crude oil refining sector for fiscal 1998 increased over
fiscal 1997 due to increased activity in the international markets.

     Revenues from the petrochemical processing and oil and gas exploration and
production sectors were not segregated during fiscal 1997; therefore,
explanations of variances are not available. The decline in other sector
revenues in fiscal 1998 is the result of a decline in revenues from our pipe
fabrication and bending operations in 1998 due to the substantial completion of
a large mining contract in fiscal 1997.

     Gross profit margins in fiscal 1998 decreased to 15.9% from 19.1% for
fiscal 1997 due primarily to the following factors:

     - a higher volume of pipe erection, maintenance and related construction
       services work in fiscal 1998, which typically produces a lower gross
       profit margin;
     - reduced gross profit margins on our manufactured products due to pricing
       pressure from foreign imports in fiscal 1998; and
     - lower profit margins realized from our United Kingdom operations since
       the acquisition of Pipework Engineering and Development and Prospect.

     General and administrative expenses were $48.5 million for fiscal 1998, up
29.7% from $37.4 million for fiscal 1997. Approximately $9 million of the
increase relates to general and administrative expenses of newly acquired
subsidiaries, including those owned for only part of fiscal 1997. The remaining
increase is related to increased corporate overhead costs due to the general
expansion of our operations. However, as a percentage of revenues, general and
administrative expenses decreased from 11.2% in fiscal 1997 to 9.7% in fiscal
1998.

     Interest expense for fiscal 1998 was $8.5 million, up 25.0% from $6.8
million in fiscal 1997, primarily due to increased borrowings to expand our
business and to complete the acquisitions of Prospect, Cojafex, Pipework
Engineering and Development and Lancas in 1998.

     Our effective tax rates for fiscal 1997 and fiscal 1998 were 30.6% and
30.2%, respectively. The decrease in the fiscal 1998 rates from fiscal 1997 was
primarily due to additional tax savings from higher foreign export sales and
foreign sourced income taxed at lower rates, partially offset by lower state
income tax incentives and refunds.

LIQUIDITY AND CAPITAL RESOURCES

     Net cash provided by operations was $26.9 million for fiscal 1999, compared
to net cash used in operations of $3.2 million for fiscal 1998. For fiscal 1999,
net cash was favorably impacted primarily by net income of $18.1 million,
depreciation and amortization of $13.3 million, deferred income taxes of $3.7
million, a decrease in receivables of $15.6 million and an increase in accrued
liabilities of $4.3 million. Offsetting these positive factors were increases of
$12.2 million in inventories and $4.5 million in cost and estimated earnings in
excess of billings on uncompleted contracts and decreases of $7.7 million in
accounts payable and $4.0 million in advanced billings and billings in excess of
cost and estimated earnings on uncompleted contracts.

     The decrease in receivables was primarily attributable to increased
collection efforts. The increase in inventory was due to the recent purchase of
a large quantity of materials from foreign markets at favorable prices and a
higher amount of work-in-progress inventory at year-end due to the increased
volume of work on hand, particularly in our fabrication facilities. Accounts
payables and accrued liabilities changed due to normal operating activities and
the timing of receipts and payment of invoices from vendors. Changes in cost and
estimated earnings in excess of billings, advanced billings and billings in
excess of cost and estimated earnings on uncompleted contracts relate to the
changes in contractual terms negotiated with customers each year.

     Net cash used in investing activities was $30.3 million for fiscal 1999,
compared to $38.0 million for fiscal 1998. During fiscal 1999, we purchased
$18.0 million of property and equipment, including $6.5 million for a new
corporate facility in Baton Rouge, Louisiana, $5.7 million of construction
equipment and $5.8 million of other property and equipment. During fiscal 1999,
we also embarked on our first significant project financing participation. In
connection with our construction and maintenance work on a refinery project in
Norco, Louisiana, we acquired $12.5 million of 15% senior secured notes due
December 1, 2003 and shares of preferred stock. The notes are secured by a first
priority security interest in some of the refinery's assets. Through December 1,
2000, we expect to receive additional notes in lieu of interest. Our investment
in the notes was $13.8 million as of August 31, 1999. This investment represents
a one-time investment, although we may from time to time pursue similar
investments on a

                                       23
<PAGE>   27

selective basis. This type of investment will generally be limited in size to
the profit we expect to receive from the projects and will carry a return that
we believe reflects the risk inherent in our investment. These uses of cash were
partially offset by proceeds from the sale of property and equipment of $1.5
million. In fiscal 1998, in addition to $14.6 million of purchases of property
and equipment, we invested $27.7 million, net of cash received, in the Pipework
Engineering and Development, Prospect, Lancas, Cojafex and Bagwell acquisitions.

     Net cash provided by financing activities totaled $6.8 million for fiscal
1999, compared to $40.8 million provided in fiscal 1998. Net borrowings from our
revolving lines of credit totaled $22.7 million in fiscal 1999. Our revolving
line of credit has been generally used to provide working capital and fund fixed
asset and subsidiary acquisitions. During fiscal 1999, we also used our
revolving credit facility to repurchase 1,561,320 shares of our common stock for
$13.7 million (including brokerage commissions) through open market and block
transactions in accordance with a plan adopted by our board of directors. In
September 1999, our board of directors voted to terminate our stock repurchase
plan. Cash was also provided by $5.6 million of new debt and a $2.6 million
increase in short-term liabilities while funds of $10.7 million were used to
repay outstanding debt. In fiscal 1998, $62.2 million of cash was provided from
the issuance of new debt, primarily $60 million of senior secured notes funded
in May 1998. The proceeds from the senior secured notes were used primarily to
pay down our revolving line of credit, which had reached a balance of $69.5
million. Cash provided by financing activities in fiscal 1998 was $40.8 million,
primarily from the $62.2 million of new debt, net repayments on the revolving
lines of credit of $10.2 million and the repayment of debt and leases of $13.8
million.

     In September 1999, the maturity date of our revolving line of credit was
extended to May 31, 2002. The amendment also modified the interest rate spread
not to exceed, at our election, 2.50% over the London Interbank Offering Rate or
1.75% over the Prime Rate. The facility permits us to borrow up to $100 million
in principal amount subject to our satisfaction of the conditions to borrowing
set forth in the facility. The credit facility contains covenants that are
customary for revolving loan agreements of this nature. Our credit facility and
senior secured notes are equally ranked and are secured by domestic subsidiary
accounts receivable, inventory, intangible assets and bank deposits, as well as
by the pledge of the capital stock of some of our domestic subsidiaries. We
believe that our current financing arrangements are sufficient to support our
operations for the next twelve months.

YEAR 2000 COMPLIANCE

     The year 2000 or Y2K issue is the result of computerized systems being
written to store and process the year portion of dates using two digits rather
than four. Date-sensitive systems may fail or produce erroneous results because
the year 2000 may be interpreted as the year 1900. During 1998, we began
implementation of a program to identify, evaluate and address our Y2K risks to
ensure that our information technology systems and non-information technology
systems are able to process dates from and after January 1, 2000 without
critical systems failure. In addition to evaluating our own systems, we assessed
the Y2K risks associated with our significant customers and suppliers.

     In general, our program for identifying, evaluating and addressing our Y2K
risks for all of our systems involved preliminary assessments by our personnel
and detail audits and assessments by consultants. We completed this phase in the
fourth quarter of fiscal 1999. Total outside costs of approximately $412,000,
consisting primarily of consultant expenses, were incurred and expensed in
fiscal 1999 during this evaluation and assessment process. We incurred no
outside costs in fiscal 1998.

     We segmented the analysis of our systems into local, national and
international categories. We divided each category into major business areas
consisting of systems, products, facilities, and suppliers. We divided these
business areas into smaller categories for data collection and evaluation, such
as computers, network equipment, production equipment, manufacturing equipment,
alarm systems and phone systems.

                                       24
<PAGE>   28

We entered the data into a repository that was created to track evaluation and
remediation efforts. The following is an example of the methodology and results
gathered during our year 2000 program:

 Systems

     We identified our proprietary and off-the-shelf systems during the
inventory phases of our Y2K program. Our proprietary software has been
remediated and tested for year 2000 problems. Year 2000 compliant software has
been installed on all production systems. A testing methodology used for these
proprietary systems, in an identical but separate environment, was established
to evaluate operational functionality and current, future and crossover dates
between the years 1999 and 2000. We upgraded other business critical
off-the-shelf applications according to the directions of manufacturers to meet
year 2000 compliance specifications.

 Products

     After an inventory and evaluation, we believe that the majority of our
products are generally not vulnerable to year 2000 problems. Design
modifications are being implemented to our Cojafex bending machines, our only
significant products with imbedded technology, to assure Y2K compliance of
future machines. We believe that, while certain reporting functions may be
impacted, the production functionality of Cojafex machines previously sold will
not be adversely affected by Y2K problems.

 Facilities

     We have evaluated our facilities for Y2K purposes, including phone systems,
HVAC, alarm systems, fire systems, elevators and electrical power. We evaluated
these items because of their potential impact on business operations if they
were to fail. To date, we have not discovered that any of our business
facilities are materially noncompliant with our Y2K requirements.

 Suppliers

     We believe the most likely Y2K problem that we may experience would be a
temporary disruption in certain materials and services provided to us by third
parties. These disruptions could have a material adverse effect on us. We have
attempted to identify and classify business suppliers based on relevant priority
factors and have contacted numerous suppliers and potential suppliers regarding
their Y2K compliance. We believe that we will be able to replace non-compliant
vendors; however, certain types of raw materials are available from only one or
a few specialized suppliers. To date, we believe that we have contacted all
suppliers material to our operations about their compliance efforts and status.
We have not discovered any problems that we believe will materially adversely
affect us, but we cannot assure you that problems of this nature will not arise.

 Current Assessment

     We will continue our Y2K contingency planning and compliance monitoring
through January 2000.

     Based upon the outcome of our assessments and the information derived from
our significant customers and suppliers, we are currently developing contingency
plans to address certain risks. However, we cannot assure you that we will not
be materially adversely affected by Y2K problems.

     We also believe that the cost to modify or replace our non-compliant
systems should not exceed $700,000, bringing our total expected Y2K expenditures
paid to outside sources to a maximum of $1,112,000. We have incurred
approximately $435,000 in Y2K-related expenses to date. We cannot assure you,
however, that such costs will not escalate and materially and negatively impact
us.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1997, SFAS No. 131 -- "Disclosures about Segments of an Enterprise
and Related Information" was issued. SFAS 131 requires us to report financial
and descriptive information about our
                                       25
<PAGE>   29

operating segments in our financial statements. The required disclosures are
made for the first time in our fiscal 1999 financial statements included in this
prospectus.

     In early 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities." The statement is effective for fiscal years beginning after
December 15, 1998 and will require costs of start-up activities and organization
costs to be expensed as incurred. Any unamortized costs on the date of adoption
of the new standard will be written off and reflected as a cumulative effect of
a change in accounting principle. As of August 31, 1999, we had total deferred
organizational costs of approximately $492,000. We intend to adopt this new
requirement in fiscal 2000.

     During fiscal 1999, the Financial Accounting Standards Board issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities." The
statement establishes accounting and reporting standards for derivative
instruments and for hedging activities. It requires that an entity recognize all
derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. Changes in a derivative's
fair value are to be recognized currently in earnings unless specific hedge
accounting criteria are met. We will be required to adopt SFAS No. 133, as
amended by SFAS No. 137 which defers the effective date, on September 1, 2000.
We have not yet quantified the impact on our financial statements that may
result from adoption of SFAS No. 133; however, we do not use derivative
instruments or hedging activities extensively in our business.

                                    BUSINESS

THE SHAW GROUP INC.

     We are the largest supplier of fabricated piping systems in the United
States and one of the leading suppliers of integrated piping systems and
services for new construction, site expansion and retrofit projects in the
world. We are a cost-effective single-source provider of fabricated piping
systems and services for projects primarily in the following industries:

     - power generation;
     - chemical processing;
     - crude oil refining;
     - petrochemical processing; and
     - oil and gas exploration and production.

     By serving a diverse portfolio of industries worldwide, we reduce our
dependence on any one industry or geographic region. We are currently
benefitting from substantial demand for our products and services in the power
generation industry, particularly for activity related to the installation of
gas turbine power systems in the United States. We believe that we have provided
more piping systems for the power generation market worldwide than any other
domestic competitor, positioning us to capitalize on the significant and growing
demand in this sector.

     We differentiate ourselves from our competition by offering our customers
comprehensive piping solutions consisting of integrated engineering, design,
fabrication, erection and maintenance of piping systems and the manufacture of
pipe fittings. Over the past several years, our customers have included:

<TABLE>

Hitachi                                         Toshiba Corporation
</TABLE>

     We have also formed strategic alliances with:

<TABLE>
<S>                                             <C>
ABB AG                                          The Dow Chemical Company
Air Products and Chemicals, Inc.                General Electric Company
Alstom S.A.                                     Orion Refining Corporation
BASF AG                                         Parsons Corporation
Bechtel Corporation                             Praxair, Inc.
</TABLE>

     We were founded in 1987 and have expanded rapidly through internal growth
and the completion and integration of a series of strategic acquisitions. We
have increased our revenues from $131.1 million for fiscal 1994 to $494.0
million for fiscal 1999, representing a 30% compound annual growth rate. Over
this same time period, we have also achieved a 30% compound annual growth rate
in earnings per share. In addition, our backlog has increased from $75.0 million
as of August 31, 1994 to $818.3 million as of August 31, 1999.

OUR COMPETITIVE ADVANTAGES

     Over the past several years, we have increased our pipe fabrication
capacity, expanded our products and services, and broadened the scope of our
projects to include engineering, pipe erection, maintenance and related
construction services. These initiatives have enabled us to become a
technologically advanced producer of complex piping systems, to achieve
substantial economies of scale in purchasing raw materials

                                       27
<PAGE>   31

and to provide our customers with a broad range of products and services. As a
result, we benefit from the following competitive advantages:

          Coordination and integration of piping systems and services. Our
     ability to provide our customers with a single source of comprehensive
     piping products and services and to coordinate and integrate our products
     and services allows us to maximize project efficiency and reduce lead time
     and costs for our customers.

          State-of-the-art induction pipe bending technology. Traditionally,
     pipe fabricators cut and connect pipe through the use of fittings that are
     welded into place. While a significant amount of our fabrication is still
     based on this method, pipe bending techniques such as ours have grown in
     acceptance in recent years. Pipe bending techniques require fewer cut and
     weld connections than the traditional method and as a result require less
     labor and material expenditures. Induction bending is a technique using
     simultaneous super-heating and compression of pipe to produce tight-radius
     bends to our customers' specifications. We believe that we offer our
     customers the most sophisticated and efficient induction pipe bending
     machines and technology available in the world today. Our induction pipe
     bending machines are capable of bending pipe as large as 66 inches in
     diameter with a wall thickness of up to five inches. In addition, when
     compared to the traditional cut and weld method, our technology provides a
     more uniform and cost-effective product that is generally considered to be
     stronger and less prone to structural fatigue.

          Established, diversified customer base. Our customers include a group
     of large, multi-national companies with whom we have long-standing
     relationships. In some cases, these relationships have taken the form of
     strategic alliances through which we provide a significant portion of our
     customers' piping requirements. Because many of our customers are active in
     more than one of the industries we serve, they have historically remained
     significant purchasers of our piping systems and services despite
     fluctuations in activity within any particular industry.

          Strategically positioned worldwide operations. We have established a
     leading market position in the United States and have devoted substantial
     resources to select international markets in South America, Europe, Asia
     and Australia. Our pipe fabrication facilities currently include eight
     locations in the United States and four in international markets. These
     facilities consist of over 1.5 million square feet of fabrication space and
     can produce more than 97,000 tons of fabricated pipe annually. In the past
     two fiscal years, we have fabricated products in our overseas facilities
     representing approximately one-half of our international sales. We believe
     that our international presence strengthens our ability to pursue new
     markets and customers on a global basis, particularly multi-national
     customers seeking suppliers who can provide worldwide solutions for their
     piping requirements. For example, in the past six years one of our alliance
     partners has installed our systems in 24 power plants in 13 countries on
     three continents.

          Proprietary software technology. Our proprietary SHAW-DRAW(TM) and
     SHAW-MAN(TM) software programs enhance our customers' ability to plan,
     schedule and track their projects and reduce installation costs and cycle
     times. SHAW-DRAW(TM) converts customer designs into production drawings
     while SHAW-MAN(TM) manages and controls the movement of project materials.
     Many of our customers have found our software to be of such value that they
     have electronically linked their own planning and control processes with
     our systems and software.

          Specialty manufacturing capability. While our competitors are
     generally dependent on third-party manufacturers of specialty fittings, we
     have the capability to manufacture many of these products in-house. By
     manufacturing these critical elements of the pipe fabrication process, we
     are able to maintain greater control over the sourcing of fittings, which
     reduces our supply costs and minimizes delays in fabrication.

                                       28

OUR BUSINESS STRATEGY

     Our business strategy is to enhance our leading position as a provider of
comprehensive piping solutions within existing markets and to enter select new
markets. We intend to achieve this goal by:

          Growing through internal development. Our fabrication facilities are
     currently operating at or near capacity while our backlog has more than
     tripled in the last year. In order to meet projected demand, we anticipate
     developing or acquiring one or more facilities in the next year. We will
     also hire additional sales, marketing and project maintenance personnel
     worldwide as well as purchase and upgrade equipment and technology. In
     addition to increasing our plant capacity and strengthening our sales,
     manufacturing and technology infrastructure, we intend to evaluate
     opportunities to enter new international markets, particularly those in
     which significant power plant construction is anticipated.

          Pursuing alliance agreements. We intend to enter into additional
     alliance agreements with current and future customers. Our alliance
     agreements enhance our ability to obtain contracts for individual projects
     by eliminating formal bid preparation. The alliance process involves joint
     steering committees in which we work closely with our customers to achieve
     process improvements and systems integration. We believe that our ongoing
     dialogue with our alliance partners greatly enhances our customer
     relationships. These agreements have tended to provide us with a steady
     source of projects, minimize the impact of short-term pricing volatility
     and enable us to anticipate a larger portion of our future revenues.

          Strengthening our technological position. We will continue to
     strengthen our technological position through investment in new equipment,
     technology and information systems, which we believe will allow us to
     increase our fabrication and manufacturing capabilities and capacity,
     better integrate our product and service offerings and improve overall
     project efficiency. In addition, to address our customers' desire to share
     project information with us electronically, we are developing information
     systems to enable our customers to monitor closely the progress of their
     piping projects and to integrate fully the installation and erection of the
     entire piping project.

          Expanding our erection, maintenance and related construction
     services. We have developed expertise in providing erection, maintenance
     and construction services related to our core fabrication projects. We
     believe that our ability to offer these services appeals to many of our
     customers and provides us with significant growth opportunities.

          Pursuing selective acquisitions. Since October 1996 we have completed
     11 acquisitions for total consideration of approximately $93 million. We
     intend to continue to pursue selective acquisitions of businesses that will
     expand or complement our current portfolio of products and services.

INDUSTRY OVERVIEW

     Our industry provides piping systems and services for projects in the power
generation, chemical processing, crude oil refining, petrochemical processing,
oil and gas exploration and production, and other industries including pulp and
paper, food processing and pharmaceutical industries. Because these industries
have historically been cyclical and affected by general downturns in the
economy, our revenues and the revenues of our competitors have fluctuated with
the demand by these industries for new construction and site expansions, while
maintenance work has typically been more recurring in nature.

  Power Generation

     According to the Department of Energy, demand for domestic electricity
generation has increased 17% since 1990 while capacity has increased less than
one percent. This imbalance, coupled with deregulation of the power industry and
decommissioning of nuclear plants, has resulted in a surge in domestic
construction of power plants. According to the Energy Information
Administration, or EIA, a projected 1,344 new plants with a total of 403
gigawatts of capacity will be needed by 2020 to meet growing demand and to
offset retirements of nuclear and fossil fuel plants. Approximately 85% of new
capacity is projected to be combined-cycle or combustion turbine technology
fueled by natural gas or both
                                       29
<PAGE>   33

oil and gas. The EIA estimates that between 1995 and 2010 approximately $1.4
trillion will be spent on electricity generation investments worldwide. Our
backlog reflects this activity; at August 31, 1999, we had approximately $527
million in backlog attributable to the power generation industry, representing
approximately 64% of our total backlog on that date.

  Chemical Processing

     While our chemical processing customers have experienced limited growth
overall, we have continued to experience relatively steady activity in this
sector. We anticipate that the majority of our work in this sector in the
near-term will consist of maintenance and retrofit work necessary to modernize
existing facilities and to comply with increasingly stringent environmental
requirements. Approximately 12% of our backlog at August 31, 1999 consisted of
work in the chemical processing industry.

  Crude Oil Refining

     Demand for our services in the crude oil refining industry has remained
steady in recent years. The consistent demand for our services in this industry
has been driven by refiners' need to process a broader spectrum of crude and to
produce a greater number of products. In addition, increasingly stringent
environmental regulations, including significantly reduced emissions allowances
required by the Clean Air Act, have increased retrofit activity. The refining
industry represented approximately 19% of our backlog at August 31, 1999.

  Petrochemical Processing

     The petrochemical processing industry has experienced a downturn over the
past several years and our activity in this sector also diminished in fiscal
1999. Similar to the chemical processing industry, most of our work in this
sector will be driven by maintenance and retrofit requirements. Projects in the
petrochemical processing sector represented an insignificant percentage of our
backlog at August 31, 1999.

  Oil and Gas Exploration and Production

     We entered the domestic offshore oil and gas exploration and production
market with the acquisition of Bagwell Brothers, Inc. in fiscal 1998. Although
demand in this industry is directly related to capital spending in the oil and
gas sector which, in turn, is directly influenced by the levels of oil and gas
prices, demand for our products and services lags behind significant commodity
price increases. Since January 1, 1999, West Texas Intermediate crude oil and
Henry Hub natural gas prices have increased approximately 86% and 35%,
respectively. As a result of the improving commodity price outlook, a number of
independent and major oil and gas companies have increased capital expenditure
budgets for the second half of 1999 and for 2000. As a result of increases in
capital expenditures, our bidding activity in this sector has increased in
recent months. Approximately four percent of our backlog at August 31, 1999
consisted of projects in the oil and gas exploration and production industry.
While we do not expect to experience significantly higher activity rates in this
sector in the near-term, we believe we are well positioned to take advantage of
significant opportunities for growth both domestically and internationally.

PRODUCTS AND SERVICES

     We have set forth below a brief description of each of our major products
and services.

  Fabrication

     Our primary service is the fabrication of complex piping systems from raw
materials including carbon steel, stainless steel and other alloys, nickel,
titanium and aluminum. We fabricate pipe by cutting it to length, welding
fittings on the pipe and bending the pipe, each to precise customer
specifications. We currently operate pipe fabrication facilities in Louisiana,
Oklahoma, South Carolina, Texas, Utah, Virginia,

                                       30
<PAGE>   34

the United Kingdom, Venezuela and Bahrain, where we have a 49% interest in a
joint venture. Our fabrication facilities are capable of fabricating pipe
ranging in diameter from 1/2 inch to 72 inches, with overall wall thicknesses
from 1/8 inch to 7 inches. We can fabricate pipe assemblies up to 100 feet in
length and weighing up to 45 tons.

     A significant portion of our work consists of the fabrication of critical
piping systems for use in high pressure, high temperature or corrosive
applications, including systems designed to withstand pressures of up to 2,700
pounds per square inch and temperatures of up to 1,020 degrees Fahrenheit. In
order to ensure that our products can withstand these types of extreme
conditions, we have set rigid quality control standards for all of our products.
In addition to visual inspection, we use other advanced methods to confirm that
our products meet specifications such as:

     - radiography;
     - hydro testing;
     - dye penetration; and
     - ultrasonic flaw detection.

  Induction Pipe Bending

     In fiscal 1994, we began purchasing state-of-the-art induction pipe bending
equipment, which significantly increased our capacity to fabricate piping
systems in both volume and complexity. In addition, this equipment enables us to
substitute pipe bending for the more traditional cutting and welding techniques
on certain projects, resulting in labor, time and raw material savings. In
January 1998, we acquired Cojafex B.V. of Rotterdam, Holland. Cojafex owns the
technology for certain induction pipe bending machines used for bending pipe and
other carbon steel and alloy items for industrial, commercial and architectural
applications.

     Primarily because of the significant reductions in labor, time and material
costs associated with pipe bending techniques, the market for pipe fabrication
is increasingly moving in the direction of bending according to customer
specifications. We believe that our technology is the most advanced of its kind
available in the world and gives us a technological advantage in this growing
segment of the market.

     We currently have eight induction pipe bending machines in operation
capable of bending pipe up to 66 inches in diameter with wall thicknesses of up
to five inches. Their model numbers, locations and pipe bending capabilities are
presented in the following table:

  Engineering and Design

     In 1994, as an integral part of our strategy to offer comprehensive piping
solutions, we expanded our services to include engineering and design
capabilities for power projects, primarily for our customers outside the United
States. We also design and engineer pipe hangers and pipe support systems and
specialize in engineering analyses of complex piping systems and related
services, primarily for the power generation industry. These engineering, design
and pipe support capabilities complement our fabrication

                                       31
<PAGE>   35

services, particularly for power generation projects, enabling us to provide
more comprehensive piping packages with reduced overall lead times and lower
total installed costs.

     We use sophisticated plant design software to create virtual
three-dimensional piping system models. The models provide customers with a
clear, understandable picture of the complete project, enabling them to "walk
through" the project on a three-dimensional basis to accurately review designs.
We currently operate approximately 25 workstations that utilize this plant
design software.

     Our engineering capabilities are directly linked to our fabrication shops
and our proprietary computer aided design system, SHAW-DRAW(TM). SHAW-DRAW(TM)
converts customer design drawings into our detailed production drawings in
seconds, significantly reducing the lead-time required before fabrication can
begin and substantially eliminating detailing errors. We have also implemented
SHAW-MAN(TM), which efficiently manages and controls the movement of all
required materials through each stage of the fabrication process utilizing bar
code technology. These proprietary programs enhance our customers' planning and
scheduling, reducing total installed costs and project cycle times.

  Erection and Maintenance

     Our acquisition of several industrial erection and maintenance businesses
in fiscal 1997 and 1998 has enabled us to expand our piping solutions to include
on-site piping system erection services and total project construction and plant
maintenance services. We currently offer erection and maintenance services in
the Gulf Coast region of the United States and in the United Kingdom, Australia
and Venezuela.

     Our erection projects are generally capital-intensive and include the
construction of new facilities, plant expansions and upgrades. Our services
incorporate most of the construction disciplines, including:

     - civil, structural and steel erection;
     - mechanical and equipment installation and assembly;
     - piping erection;
     - skid and modular unit fabrication and assembly;
     - constructability reviews;
     - materials and labor procurement and management;
     - American Society of Mechanical Engineers code work; and
     - plant maintenance.

  Specialty Fittings Manufacturing and Distribution

     We manufacture specialty stainless, alloy and carbon steel pipe fittings
for use in pipe fabrication. These pipe fittings include stainless and other
alloy elbows, tees, reducers and stub ends ranging in size from 1/2 inch to 48
inches and heavy wall carbon and chrome elbows, tees, caps and reducers with
wall thicknesses of up to 3 1/2 inches. We operate a manufacturing facility in
Shreveport, Louisiana, which distributes our fittings to our pipe services
operations and to third parties. We also operate several distribution centers in
the United States, which distribute our products as well as products
manufactured by third parties. Manufacturing pipe fittings enables us to realize
greater efficiencies in the purchase of raw materials, reduces overall lead
times and lowers total installed costs. Our manufacturing capabilities also
reflect our commitment to be a comprehensive piping solution for our customers.

MARKETS

     Our principal markets are the erection of new systems and retrofits in the
power generation, chemical processing, crude oil refining, petrochemical
processing and oil and gas exploration and production industries, both in the
United States and internationally. We also have supplied piping systems to other
industries including the pulp and paper, food processing and pharmaceutical
industries.

</TABLE>

     Prior to February 1994, we conducted our international business exclusively
from our plants in the United States. Critical or high pressure piping systems
are typically fabricated in industrialized nations that tend to have greater
capacity for manufacturing piping that satisfies stringent tolerance and
consistency requirements. United States pipe fabricators have generally
fabricated these systems more efficiently than their Western European and
Japanese competitors due to lower labor costs and greater availability of raw
materials. However, geographical sourcing requirements, local labor rates and
transportation considerations may make it difficult for us to use our domestic
facilities to compete on many international projects, particularly those
involving non-critical piping systems. Therefore, we have established facilities
abroad to allow us to bid more competitively for international projects. We
currently operate facilities in Venezuela, the United Kingdom, Australia and
Bahrain.

     In November 1993, we entered into a joint-venture agreement to construct
and operate a fabrication facility in Bahrain. Our joint venture partner is
Abdulla Ahmed Nass, a Bahrainian industrialist. Our Bahrainian joint-venture
facility is one of the first modern pipe fabrication facilities in the Middle
East and has received the Gulf States Certification from the Gulf Cooperation
Council. The Gulf States Certification enables the joint venture to export
products to other Arab countries without paying additional tariffs. In fiscal
1999, the joint venture had sales of approximately $9.6 million and our share of
the joint venture's net income was approximately $681,000.

     In the future, our pursuit of joint-venture relationships to conduct
foreign operations will be determined on a case-by-case basis depending on
market, operational, legal and other relevant factors.

BACKLOG

     We define our backlog as a "working backlog," which includes projects for
which we have received a commitment from our customers. This commitment
typically takes the form of a written contract for a

                                       33
<PAGE>   37

specific project, a purchase order or a specific indication of the amount of
time or material we need to make available for a customer's anticipated project.
In certain instances the engagement is for a particular product or project for
which we estimate anticipated revenue, often based on engineering and design
specifications that have not been finalized and may be revised over time. Our
backlog for maintenance work is derived from maintenance contracts and our
customers' historic maintenance requirements. We estimate that our backlog was
approximately $818.3 million at August 31, 1999, compared to $253.4 million and
$254.3 million at August 31, 1997 and 1998, respectively. We estimate that
$403.5 million, or 49%, of our backlog at August 31, 1999 will be completed in
fiscal 2000.

     Approximately $300 million, or 37%, of our backlog at August 31, 1999 was
attributable to a contract with General Electric that requires us to fabricate
90% of the pipe necessary to install the combined-cycle gas turbines to be built
by General Electric domestically through 2004. Approximately 53% of this backlog
is for power generation projects for which General Electric has been engaged and
is in various stages of design, engineering and construction and for which we
have received a work release or have been notified that a work release is
pending. The balance is for work for which General Electric has requested that
we reserve capacity. We cannot assure you that all of these projects will be
constructed or that they will be completed in our currently anticipated time
frame.

     On occasion, customers will cancel or delay projects for reasons beyond our
control. Most of our contracts provide for cancellation fees in the event
projects in backlog are canceled but we typically have no contractual right to
the total revenues reflected in our backlog. These fees typically provide for
reimbursement of our out-of-pocket costs, revenue associated with work performed
to date and a varying percentage of the profits we would have realized had the
contract been completed. Where we do not have a written agreement, we often have
been able to recover similar amounts from our clients. In addition to
cancellation risks, projects may remain in our backlog for extended periods of
time. Historically, delays have impacted our operations from time to time, but
cancellations have been immaterial. Cancellation is more likely to occur during
the initial phases of projects, when erection and related construction services
are provided, than during later phases, when fabrication services are provided.
Accordingly, cancellation rates for projects reflected in our backlog may
increase in the future if our business mix includes a larger percentage of
erection and related construction services.

     The following table breaks out the percentage of our backlog in the
following industry sectors and geographic regions for the periods indicated:

TYPES OF CONTRACTS

     Our contracts are generally priced on a unit price, fixed price or lump-sum
or cost-plus basis.

                                       34
<PAGE>   38

     A significant portion of our contracts, particularly for domestic piping
fabrication, are bid on a unit price basis under which the customer pays a
negotiated rate for the product or service, such as a weld, radiograph
inspection, bend or engineering revision. We generally bill raw materials to
customers at published prices in effect on the date of the contract, and we
generally obtain fixed pricing commitments from our suppliers at that time for
most of the items necessary to complete the project in order to minimize the
risk of raw material price increases during the fabrication process.

     We quote many of our projects on a fixed price or lump-sum basis. To
minimize the risk of increases in the cost of our supplies, we generally do not
quote the actual contract price until we have secured fixed pricing commitments
from our suppliers for most of the items necessary to complete the project.

     Additionally, a significant portion of our erection contracts are bid on a
cost-plus basis. Revenues are recognized on the basis of costs incurred plus the
fee earned.

     We obtain orders through competitive bidding, negotiated contracts and
awards under alliance agreements. In addition to price, the awarding of
contracts is often based on other factors, including reputation, experience and
ability to meet project deadlines.

     We also obtain orders under alliance agreements entered into with our
customers to expedite individual project contract negotiations through means
other than the formal bidding process. These agreements typically contain a
standardized set of purchasing terms and pre-negotiated pricing provisions and
often provide for annual price adjustments. Our current alliance partners
include ABB AG, Air Products and Chemicals, Inc., Alstom S.A., BASF AG, Bechtel
Corporation, The Dow Chemical Company, General Electric, Orion Refining
Corporation, Parsons Corporation and Praxair, Inc. These agreements are
typically implemented by establishing a joint steering committee to provide
guidance and direction on alliance issues. Normally this committee meets on a
periodic basis to monitor alliance progress and assign resources to effect
continuous improvements in the various work processes associated with project
execution. Alliance agreements allow our customers to achieve greater cost
efficiencies and reduced cycle times in the design and fabrication of complex
piping systems for power, chemical and refinery projects. In addition, we
believe that these agreements provide us with a steady source of new projects
and help minimize the impact of short-term pricing volatility. The recurring
nature of our alliance agreements also enables us to anticipate a larger portion
of our future revenues. In fiscal 1999, approximately 35% of our revenues were
generated under our alliance agreements.

CUSTOMERS AND MARKETING

     Our customers are principally major multi-national engineering and
construction firms, equipment manufacturers and industrial corporations. For
fiscal 1999, Orion Refining Corporation represented 14% of our sales while no
other customer represented more than ten percent of our sales.

     We conduct our marketing efforts principally through a sales force
comprised of 35 employees at August 31, 1999. In addition, we engage independent
contractors to cover certain customers and territories. We pay our sales force a
base salary plus, when applicable, an annual bonus, while we pay independent
contractors commissions.

RAW MATERIALS AND SUPPLIERS

     Our principal raw materials are carbon steel, stainless steel and other
alloy piping, which we obtain from a number of domestic and foreign primary
steel producers. The market for most raw materials is extremely competitive and
our relationships with our suppliers are good. Certain types of raw materials,
however, are available from only one or a few specialized suppliers. Our
inability to obtain materials from these suppliers could jeopardize our ability
to timely complete a project or realize a profit.

     We purchase directly from manufacturers, or manufacture ourselves, a
majority of our pipe fittings. This generally lowers our pipe fabrication costs.
Because of the volume of piping we purchase, we are often able to negotiate
advantageous purchase prices. If a manufacturer is unable to deliver the
materials according to the negotiated terms, we may be required to purchase the
materials from another source at a
                                       35
<PAGE>   39

higher price. We keep items in stock at each of our facilities and transport
items between our facilities as required. We obtain more specialized materials
from suppliers when required for a project.

COMPETITION

     In pursuing piping engineering and fabrication projects, we experience
significant competition from competitors in both international and domestic
markets. In the United States, there are a number of smaller pipe fabricators
while, internationally, our principal competitors are divisions of large
industrial firms. Some of our competitors, primarily in the international
sector, have greater financial and other resources than we do.

     In erection, maintenance and related construction services, we have
numerous regional, national and international competitors, many of which have
greater financial and other resources than we do. Moreover, we are a recent
entrant into this business, and many of our competitors also possess
substantially greater experience, market knowledge and customer relationships
than we do.

                          DESCRIPTION OF CAPITAL STOCK

     Our authorized capital stock consists of 50,000,000 shares of common stock,
no par value, and 5,000,000 shares of preferred stock, no par value. The
following summary of certain provisions of our capital stock does not purport to
be complete and is subject to and is qualified in its entirety by our articles
of incorporation and by-laws, which are incorporated in this prospectus by
reference as exhibits to the registration statement of which this prospectus
forms a part, and by the provisions of applicable law.

COMMON STOCK

     At August 31, 1999, there were 11,736,046 shares of common stock
outstanding. In addition, at August 31, 1999, 1,645,000 shares of common stock
were reserved for issuance pursuant to our 1993 Employee Stock Option Plan and
50,000 shares of common stock were reserved for issuance under our 1996
Non-Employee Director Stock Option Plan. Cumulative voting is prohibited in the
election of directors. Our common stock is not redeemable, does not have any
conversion rights and is not subject to call by us. Holders of our common stock
have no preemptive rights to maintain their respective percentage of ownership
in future offerings or sales of stock by us. In addition to the voting rights
described below, ownership of our common stock entitles holders to the right:

     - to receive ratably such dividends, if any, as may be declared from time
       to time by our board of directors out of funds legally available for
       dividends; and

     - in the event of our liquidation, dissolution or winding up, to share
       equally and ratably in the assets available for distribution after
       payment of all liabilities and subject to any prior rights of any holders
       of preferred stock then outstanding.

     The shares of common stock presently outstanding are fully paid and
non-assessable. Our common stock trades on the New York Stock Exchange under the
symbol "SGR."

     Each outstanding share of common stock for which there has been no change
in beneficial ownership during the four years preceding the record date will
entitle its holder to five votes on each matter properly submitted to our
shareholders for their vote, waiver, release or other action. Holders of shares
that have changed beneficial ownership within the four-year period will be
entitled to only one vote per share. A change in beneficial ownership of an
outstanding share of common stock is deemed to have occurred whenever a change
occurs in any person or persons who, directly or indirectly, through any
contract, agreement, arrangement, understanding, relationship or otherwise, has
or shares any of the following:

     - voting power, which includes, without limitation, the right to vote or
       the power to direct the voting power of the share of common stock;

     - investment power, which includes, without limitation, the power to direct
       the sale or other disposition of the share of common stock;

     - the right to receive or to retain the proceeds of any sale or other
       disposition of the share of common stock; or

     - the right to receive or to retain any distributions, including, without
       limitation, cash dividends, in respect of the share of common stock.

     Applying the general rules set forth above, the following events or
conditions are specifically deemed to involve a change in beneficial ownership
of a share of common stock:

     - in the absence of proof to the contrary provided in accordance with
       procedures set forth below, an outstanding share of common stock is
       transferred of record into the name of any other person, or upon the
       issuance of shares in a public offering;

     - in the case of an outstanding share of common stock held of record in the
       name of a corporation, general partnership, limited partnership, voting
       trustee, bank, trust company, broker, nominee or

                                       42
<PAGE>   46

       clearing agency, if it has not been established according to the
       procedures set forth below that there has been no change in the person or
       persons who direct the exercise of the rights referred to in the
       preceding set of bullet points with respect to the outstanding share of
       common stock during the four years immediately preceding the record date;

     - in the case of an outstanding share of common stock held of record in the
       name of any person as a trustee, agent, guardian or custodian under the
       Uniform Gifts to Minors Act as in effect in any jurisdiction, there is a
       change in the beneficiary of the trust, the principal of the agent, the
       ward of the guardian, the minor for whom the custodian is acting or a
       change in the trustee, agent, guardian or custodian; or

     - in the case of outstanding shares of common stock beneficially owned by a
       person or group of persons, who, after acquiring, directly or indirectly,
       the beneficial ownership of five percent of the outstanding shares of
       common stock, fails to notify us of the person's or group's ownership
       within ten days after the acquisition.

     Contrary provisions in our articles of incorporation aside, no change in
beneficial ownership of an outstanding share of common stock will be deemed to
have occurred solely as a result of:

     - any transfer without valuable consideration, including, without
       limitation, transfers effected by:

        -- bequest or inheritance;

        -- operation of law upon the death of an individual; or

        -- other transfers without valuable consideration, such as gifts made in
           good faith and not for the purpose of circumventing provisions of our
           articles of incorporation;

     - any changes in the beneficiary of a trust, or any distribution of an
       outstanding share of common stock from the trust, by reason of the birth,
       death, marriage or divorce of any natural person;

     - the adoption of any natural person prior to the age of 18;

     - the passage of a given period of time;

     - the attainment by any natural person of a specific age;

     - the creation or termination of any guardianship or custodial arrangement;

     - any appointment of a successor trustee, agent, guardian or custodian with
       respect to an outstanding share of common stock if neither the successor
       has nor its predecessor had the power to vote or to dispose of the share
       of common stock without further instructions from others;

     - any change in the person to whom dividends or other distributions in
       respect of an outstanding share of common stock are to be paid pursuant
       to the issuance or modification of a revocable dividend payment order;

     - any issuance of a share of common stock by us or any transfer by us of a
       share of common stock held in treasury other than in a public offering of
       the share, unless otherwise determined by the board of directors at the
       time of authorizing the issuance or transfer;

     - any giving of a proxy in connection with a solicitation of proxies
       subject to the provisions of Section 14 of the Securities Exchange Act of
       1934, as amended, and the rules and regulations thereunder;

     - any transfer, whether or not with consideration, among individuals
       related or formerly related by blood, marriage or adoption, defined as
       relatives, or between a relative and any person controlled by one or more
       relatives where the principal purpose for the transfer is to further the
       estate tax planning objectives of the transferor or of relatives of the
       transferor;

     - any appointment of a successor trustee as a result of the death of the
       predecessor trustee who was a natural person;

     - any appointment of a successor trustee who was specifically named in a
       trust instrument prior to the effective date of this offering; or

                                       43
<PAGE>   47

     - any appointment of a successor trustee as a result of the resignation,
       removal or failure to qualify of a predecessor trustee or as a result of
       mandatory retirement pursuant to the express terms of a trust instrument;
       provided, that less than 50% of the trustees administering any single
       trust will have changed, including in the percentage the appointment of
       the successor trustee, during the four-year period preceding the
       appointment of the successor trustee.

     All determinations concerning changes in beneficial ownership, or the
absence of any change, are made by our board of directors or by a transfer agent
for our common stock at our request. Written procedures designated to facilitate
the determinations have been established and may be amended by our board of
directors. These procedures should provide the manner of proof of facts that
will be accepted and the frequency with which such proof may be required to be
renewed. We and any transfer agent will be entitled to rely on any information
concerning beneficial ownership of the outstanding shares of our common stock
coming to our attention from any source and in any manner reasonably deemed by
us to be reliable. However, neither we nor any transfer agent will be charged
with any other knowledge concerning the beneficial ownership of outstanding
shares of our common stock.

     In the event of any stock split or stock dividend of our common stock, each
share acquired by reason of the split or dividend will be deemed to have been
beneficially owned by the same person from the acquisition date of the share
from which it originated.

     Each outstanding share of our common stock, whether at any particular time
the holder thereof is entitled to exercise five votes or one vote, shall be
identical to all other shares of our common stock in all respects, and together
the outstanding shares of common stock will constitute a single class of our
shares.

PREFERRED STOCK

     Our board of directors is authorized to provide for the issuance of
5,000,000 shares of preferred stock in one or more series. Our board may,
without any further vote or action by our shareholders, fix for any series the:

     - number of shares;
     - voting powers;
     - designations;
     - preferences; and
     - relative, participating, optional or other special rights and
       qualifications including:
        -- dividend rights;
        -- the dividend rate;
        -- terms of redemption;
        -- the redemption price or prices;
        -- conversion rights; and
        -- liquidation preferences.

     The issuance of preferred stock by our board of directors could adversely
affect the rights of holders of our common stock. For example, issuance of
preferred stock could result in a series of securities having preferences over
our common stock with respect to dividends and in liquidation or that could,
upon conversion or otherwise, enjoy all of the rights appurtenant to our common
stock. Our board of directors has the authority to issue preferred stock that
could be used to discourage attempts by others to obtain control of us through
merger, tender offer, proxy, consent or otherwise by making these attempts more
difficult to achieve or more costly. Our board may issue preferred stock without
shareholder approval and with voting and conversion rights that could adversely
affect the voting power of holders of common stock. There are no agreements or
understandings for the issuance of preferred stock, and our board has no present
intention to issue any shares of preferred stock.

LOUISIANA FAIR PRICE AND CONTROL ACQUISITION STATUTES

     Under Louisiana law, the acquisition of voting power, which is called a
"control share acquisition," of an "issuing public corporation" that results in
the purchaser acquiring voting power in excess of 20%, 33%
                                       44
<PAGE>   48

or 51% of the total voting power of the issuing public corporation requires
approval of a majority of the voting power of the issuing public corporation and
each class entitled to vote separately on the proposal, excluding the shares of
the acquiring person, any officer of the issuing public corporation and any
employee of the issuing public corporation who is also a director of the
corporation. Shares acquired in a control share acquisition without such
approval will have no voting rights and under certain circumstances may be
subject to redemption by the corporation. The restrictions imposed under the law
are applicable to all Louisiana corporations that fall within the definition of
an "issuing public corporation," as we do, unless the issuing public
corporation's articles of incorporation or by-laws contain a provision expressly
disclaiming them, which ours do not. Therefore, these restrictions contained in
Louisiana law apply to us.

     In addition, if particular elections were to be made by our board of
directors under the Louisiana Business Corporation Law, unless specified price
and procedural requirements were met, business combinations involving us and any
holder of 20% or more of our outstanding voting stock could be required to be
approved by at least:

     - 80% of the votes entitled to be cast by holders of the outstanding voting
       stock; and

     - two-thirds of the votes entitled to be cast by holders of our voting
       stock other than the voting stock of the 20% holder.

This provision could be regarded as a deterrent to a takeover of us and could be
applied selectively by our board of directors.

LIMITATION OF DIRECTOR AND OFFICER LIABILITY

     Our articles of incorporation contain provisions that eliminate the
personal liability of our directors and officers for:

     - monetary damages resulting from breaches of their fiduciary duty other
       than liability for breaches of the duty of loyalty, acts or omissions not
       in good faith or which involve intentional misconduct or a knowing
       violation of law;

     - violations under Section 92(D) of the Louisiana Business Corporation Law,
       relating to unlawful distributions; or

     - any transaction from which the director or officer derived an improper
       personal benefit.

Our articles of incorporation contain provisions requiring the indemnification
of our directors and officers to the fullest extent permitted by Section 83 of
the Louisiana Business Corporation Law, including circumstances in which
indemnification is otherwise discretionary. We believe that these provisions are
necessary to attract and retain qualified persons as directors and officers.

CLASSIFIED BOARD OF DIRECTORS

     Our articles of incorporation provide that if the number of directors
constituting our entire board of directors is increased to twelve or more
members, then at the next meeting of our shareholders at which directors are to
be elected, the board of directors will be divided into three classes, the
members of which will serve staggered three-year terms. We believe that a
classified board of directors could help to ensure the continuity and stability
of our board and the business strategies and policies determined by them. The
classified board provision, if implemented, could have the effect of making the
removal of incumbent directors more time-consuming and could discourage a third
party from making a tender offer or otherwise attempting to obtain control of
us, even though an attempt might be beneficial to us and our shareholders.

ADVANCE NOTICE PROVISIONS FOR PARTICULAR SHAREHOLDER ACTIONS

     Our by-laws establish an advance notice procedure with regard to the
nomination, other than by or at the direction of our board or a committee
thereof, of candidates for election as directors. This is called the

                                       45
<PAGE>   49

"nomination procedure" with respect to the election of directors, or with
respect to other matters to be brought before an annual meeting of our
shareholders, the "business procedure."

     The nomination procedure requires that a shareholder give prior written
notice, in proper form, of a planned nomination for our board of directors to
our secretary. The requirements as to the form and timing of that notice are
specified in our by-laws. If the election inspectors determine that a person was
not nominated in accordance with the nomination procedure, the person will not
be eligible for election as a director.

     Although our by-laws do not give our board any power to approve or
disapprove shareholder nominations for the election of directors or of any other
business desired by shareholders to be conducted at an annual or any other
meeting, our by-laws may:

     - have the effect of precluding a nomination for the election of directors
       or precluding the conduct of business at a particular annual meeting if
       the proper procedures are not followed; and

     - may discourage or deter a third party from conducting a solicitation of
       proxies to elect its own slate of directors or otherwise attempting to
       obtain control of us, even if the conduct of the solicitation or the
       attempt might be beneficial to us and our shareholders.

     Under the business procedure, a shareholder seeking to have any business
conducted at an annual meeting must give prior written notice, in proper form,
to our secretary. The requirements as to the form and timing of that notice are
specified in our by-laws. If the chairman or other officer presiding at a
meeting determines that an item of business was not properly brought before the
meeting in accordance with the business procedure, then that item of business
will not be conducted at the meeting.

SUPER MAJORITY PROVISIONS

     Our articles of incorporation contain provisions requiring the affirmative
vote of the holders of at least 75% of the voting power of our capital stock to
amend specific provisions of the articles, including provisions relating to the
removal of directors.

     Our articles of incorporation require the approval of the holders of at
least 75% of our outstanding shares of our common stock, not including shares
held by a related person, to approve some business combinations and related
transactions. The term "related person" includes any individual, corporation,
partnership or other entity which owns beneficially, directly or indirectly,
more than five percent of the outstanding shares of our common stock. The term
"business combination" includes, among other things:

     - any merger or consolidation of us or a subsidiary of ours which
       constitutes more than 50% of our assets, other than a merger or
       consolidation which results in our voting securities outstanding
       immediately prior to the merger or consolidation continuing to represent
       more than 50% of the combined voting power of the voting securities of
       the surviving entity;

     - any sale, lease, exchange, transfer or other disposition of more than 50%
       of our assets;

     - any reclassification of our common stock; and

     - our liquidation or dissolution.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the common stock is First Union
National Bank, Charlotte, North Carolina.

</TABLE>


     In the purchase agreement, the underwriters have agreed to purchase all of
the shares of our common stock being sold under the agreement if any of the
shares of our common stock being sold under the agreement are purchased. In the
event of a default by an underwriter, the purchase agreement provides that, in
some circumstances, the purchase commitments of nondefaulting underwriters may
be increased or the purchase agreement may be terminated.

     We have agreed to indemnify the underwriters against some liabilities,
including some liabilities under the Securities Act of 1933, or to contribute to
payments the underwriters may be required to make in respect of those
liabilities.

     The shares of common stock are being offered by the several underwriters,
subject to prior sale, when, as and if issued to and accepted by them, subject
to receipt of legal opinions and officers certificates, or waiver of these
conditions, as specified in the purchase agreement. The underwriters reserve the
right to withdraw, cancel or modify offers and to reject orders in whole or in
part.

COMMISSIONS AND DISCOUNTS


     The underwriters propose initially to offer the shares of our common stock
to the public at the offering price set forth on the cover page of this
prospectus, and to certain dealers at such price less a concession not in excess
of $.75 per share. The underwriters may allow, and such dealers may reallow, a
discount not in excess of $.10 per share to certain other dealers. After the
initial public offering, the public offering price, concession and discount may
be changed.


     The following table shows the per share and total public offering price,
the underwriting discount to be paid by us to the underwriters and the proceeds
before expenses to us. This information is presented assuming either no exercise
or full exercise by the underwriters of their over-allotment option.

OVER-ALLOTMENT OPTION


     We have granted an option to the underwriters, exercisable for 30 days
after the date of this prospectus, to purchase up to an aggregate of 450,000
additional shares of our common stock at the public offering price set forth on
the cover page of this prospectus, less the underwriting discount. The
underwriters may exercise this option solely to cover over-allotments, if any,
made on the sale of our common stock offered by this prospectus. To the extent
that the underwriters exercise this option, each underwriter will be obligated,
subject to receipt of legal opinions and officers certificates, or waiver of
these conditions, as specified in the purchase agreement, to purchase a number
of additional shares of our common stock proportionate to the underwriter's
initial amount reflected in the foregoing table.


NO SALES OF SIMILAR SECURITIES

     We, our executive officers and our directors have agreed, with exceptions
specified in the lock-up agreements, not to directly or indirectly engage in the
following activities for a period 90 days after the date of this prospectus
without the prior written consent of Merrill Lynch, Pierce, Fenner & Smith
Incorporated:

     - offer, pledge, sell, contract to sell, sell any option or contract to
       purchase, purchase any option or contract to sell, grant any option,
       right or warrant for the sale of, lend or otherwise dispose of or
       transfer any shares of our common stock or securities convertible into or
       exchangeable or exercisable for or repayable with our common stock,
       whether now owned or later acquired by the person executing the agreement
       or with respect to which the person executing the agreement later
       acquires the power of disposition, or file a registration statement under
       the Securities Act of 1933 relating to any shares of our common stock; or

     - enter into any swap or other agreement that transfers, in whole or in
       part, the economic consequence of ownership of our common stock whether
       any such swap or transaction is to be settled by delivery of our common
       stock or other securities in cash or otherwise.

PRICE STABILIZATION AND SHORT POSITIONS


     Until the distribution of our common stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the underwriters and
selling group members to bid for and purchase our common stock. As an exception
to these rules, the underwriters are permitted to engage in certain transactions
that stabilize the price of our common stock. Such transactions consist of bids
or purchases for the purpose of pegging, fixing or maintaining the price of our
common stock.



     If the underwriters create a short position in our common stock in
connection with this offering, i.e., if they sell more shares of common stock
than are set forth on the cover page of this prospectus, the underwriters may
reduce that short position by purchasing our common stock in the open market.
The underwriters may also elect to reduce any short position by exercising all
or part of the over-allotment option described above.



     Neither we nor any of the underwriters make any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of our common stock. In addition, neither
we nor any of the underwriters make any representation that the underwriters
will engage in such transactions or that such transactions, once commenced, will
not be discontinued without notice.



     John W. Sinders, Jr., one of our directors, is Managing Director of RBC
Dominion Securities Corporation. As noted above, RBC Dominion Securities
Corporation is one of the underwriters. Mr. Sinders beneficially owns 23,750
shares of our common stock.



     Jefferies & Company, Inc. is one of the underwriters in connection with our
stock repurchase program. As noted above, Jefferies & Company, Inc. is one of
the underwriters.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Shareholders
of The Shaw Group Inc.:

     We have audited the accompanying consolidated balance sheet of The Shaw
Group Inc. (a Louisiana corporation) and subsidiaries as of August 31, 1999, and
the related consolidated statements of income, shareholders' equity and cash
flows for the year ended August 31, 1999. 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.

     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 financial statements referred to above present fairly,
in all material respects, the financial position of The Shaw Group Inc. and
subsidiaries as of August 31, 1999, and the results of their operations and
their cash flows for the year ended August 31, 1999, in conformity with
generally accepted accounting principles.

To the Board of Directors and Shareholders
of The Shaw Group Inc.:

                      THE SHAW GROUP INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Principles of Consolidation

     The consolidated financial statements include the accounts of The Shaw
Group Inc. (a Louisiana corporation) and its wholly-owned subsidiaries
(collectively, the Company). All material intercompany accounts and transactions
have been eliminated in these financial statements.

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

 Nature of Operations

     The Company is a supplier of fabricated piping systems, integrated piping
systems and related services for new construction, site expansion and retrofit
projects throughout the world, primarily in the United States, the Far
East/Pacific Rim, Europe, South America and the Middle East for customers in the
power generation, chemical processing, crude oil refining, petrochemical
processing, oil and gas exploration and development and other industries. The
Company offers comprehensive design and engineering services, piping system
fabrication, industrial construction and maintenance services, manufacturing and
sale of specialty pipe fittings and design and fabrication of pipe support
systems. The Company's operations are conducted primarily through wholly-owned
subsidiaries and one joint venture.

 Cash and Cash Equivalents

     For purposes of reporting cash flows, all highly liquid investments with a
maturity of three months or less when purchased are cash equivalents. At August
31, 1998 and 1999, the Company included in cash and cash equivalents
approximately $1,200,000 and $1,300,000, respectively, the proceeds of which
came from industrial development bond financing. These funds are required to be
invested in short-term marketable securities until used for other capital
improvements.

 Accounts Receivable and Credit Risk

     The Company's customers include major multi-national construction and
engineering firms and industrial corporations. Work is performed under contract
and the Company believes that its credit risk is normally minimal. The Company
grants short-term credit to its customers.

     At August 31, 1998 and 1999, accounts receivable included approximately
$18,000,000 and $13,000,000, respectively, of receivables and claims due under
contracts which are subject to contract renegotiations or legal proceedings and
which are recorded at estimated net realizable value. At August 31, 1999,
contracts with seven customers made up the $13,000,000 balance discussed above.
Management believes that the ultimate resolution of these disputes will not have
a significant impact on future results of operations.

 Allowance for Uncollectable Receivables and Contract Adjustments

     The allowance for uncollectable receivables and contract adjustments of
approximately $7,100,000 and $5,800,000 at August 31, 1998 and 1999,
respectively, is based on management's estimate of the amount expected to be
uncollectable considering historical experience and the information management
is able to obtain regarding the financial condition of significant customers.
The Company includes contract

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

adjustments as a reduction of sales. Net provisions to this allowance were
approximately $1,700,000 in fiscal 1998. Increases to the allowance for the year
ended August 31, 1999 were $4,600,000 with total reductions of $5,900,000.
Provisions for uncollectible receivables included in bad debt expense was not
material for 1997, 1998 and 1999.

 Inventories

     Inventories are stated at the lower of cost or market. Cost is determined
using the first-in, first-out (FIFO) or weighted-average cost methods.

 Property and Equipment

     Property and equipment are recorded at cost. Additions and improvements are
capitalized. Maintenance and repair expenses are charged to income as incurred.
The cost of property and equipment sold or otherwise disposed of and the
accumulated depreciation thereon are eliminated from the property and related
accumulated depreciation accounts, and any gain or loss is credited or charged
to income.

     For financial reporting purposes, depreciation is provided by utilizing the
straight-line method over the following estimated useful service lives:

Furniture and fixtures..................................   3-7 Years
Machinery and equipment.................................  3-18 Years
Buildings and improvements..............................  8-40 Years
</TABLE>

     At August 31, 1999, the Company had equipment not yet placed into service
of $5,267,000.

 Income Taxes

     The Company provides for deferred taxes in accordance with Statement of
Financial Accounting Standards No. 109 -- "Accounting for Income Taxes," which
requires an asset and liability approach for measuring deferred tax assets and
liabilities due to temporary differences existing at year end using currently
enacted tax rates.

 Revenues

     For unit-priced pipe fabrication contracts, the Company recognizes revenues
upon completion of individual spools of production. A spool consists of piping
materials and associated shop labor to form a prefabricated unit according to
contract specifications. Spools are generally shipped to job site locations when
complete. During the fabrication process, all direct and indirect costs related
to the fabrication process are capitalized as work in progress. For lump-sum
fabrication contracts, the Company recognizes revenues based on the percentage
of completion method, measured primarily by the cost of materials for which
production is complete compared with the total estimated material costs of the
contract.

     For project management and construction services, the Company recognizes
revenues under the percentage of completion method measured primarily on
contract costs incurred to date, excluding the costs of any purchased but
uninstalled materials, compared with total estimated contract costs. Revenues
from cost-plus-fee contracts are recognized on the basis of costs incurred
during the period plus the fee earned.

     The Company recognizes revenues for pipe fittings, manufacturing operations
and other services primarily at the time of shipment or upon completion of the
services.

                      THE SHAW GROUP INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Provisions for estimated losses for uncompleted contracts are made in the
period in which such losses are identified. Other changes, including those
arising from contract penalty provisions, final contract settlements and reviews
performed by customers, are recognized in the period in which the revisions are
identified. To the extent that these adjustments result in a reduction or
elimination of previously reported profits, the Company would report such a
change by recognizing a charge against current earnings, which might be
significant depending on the size of the project or the adjustment.

 Goodwill

     Goodwill represents the excess of the purchase price of acquisitions over
the fair value of the net assets acquired. Such excess costs are being amortized
on a straight-line basis over a twenty-year period. The Company periodically
assesses the recoverability of the unamortized balance based on expected future
profitability and undiscounted future cash flows of the acquisitions and their
contribution to the overall operation of the Company.

 Financial Instruments, Forward Contracts -- Non-Trading Activities

     When considered appropriate, the Company utilizes forward foreign exchange
contracts to hedge firm purchases and sales of certain pipe bending machines.
Financial instruments are designated as a hedge at inception where there is a
direct relationship to the price risk associated with the Company's future sales
and purchases. Gains and losses on the early termination or maturity of forward
contracts designated as hedges are deferred and included in revenues in the
period the hedged transaction is recorded. If the direct relationship to price
risk ceases to exist, the difference in the carrying value and fair value of a
forward contract is recognized as a gain or loss in revenues in the period the
direct relationship ceases to exist. Future changes in fair value of the forward
contracts are recognized as gains or losses in revenues in the period of change.

 Comprehensive Income

     SFAS No. 130, "Reporting Comprehensive Income," which was required to be
adopted by the Company in the first quarter of fiscal 1999, establishes
standards for the reporting and display of comprehensive income as part of a
full set of financial statements. Comprehensive income for a period encompasses
net income and all other changes in a company's equity other than from
transactions with the company's owners.

     The foreign currency translation adjustments relate to the varying strength
of the U.S. dollar in relation to the British pound, Australian dollar and Dutch
guilder. The Company's comprehensive income is included in the consolidated
statements of shareholders' equity.

 Reclassifications

     Certain reclassifications have been made to the prior years' financial
statements in order to conform to current reporting practices.

 New Accounting Standards

     In early 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities" ("SOP"). The SOP is effective for fiscal years beginning after
December 15, 1998 and will require costs of start-up activities and organization
costs to be expensed as incurred. Any such unamortized costs on the date of
adoption of the new standard will be written off and reflected as a cumulative
effect of a change in accounting principle. As of August 31, 1999, the Company
had total deferred organizational costs of approximately $492,000.

                                      F-11

                      THE SHAW GROUP INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     During fiscal 1999, the Financial Accounting Standards Board ("FASB")
issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities." The Statement establishes accounting and reporting standards for
derivative instruments and for hedging activities. It requires that an entity
recognize all derivatives as either assets or liabilities in the statement of
financial position and measure those instruments at fair value. Changes in a
derivative's fair value are to be recognized currently in earnings unless
specific hedge accounting criteria are met. The company will be required to
adopt SFAS No. 133, as amended by SFAS No. 137 which defers the effective date,
on September 1, 2000. The Company has not yet quantified the impact on its
financial statements that may result from adoption of SFAS No. 133, however, the
Company does not use derivative instruments or hedging activities extensively in
its business.

NOTE 2 -- PUBLIC OFFERING OF COMMON STOCK

     On December 23, 1996, the Company closed the sale of 2,000,000 shares of
its common stock, no par value (the "Common Stock"), in an underwritten public
offering at a price of $21.00 per share less underwriting discounts and
commissions. On January 10, 1997, the underwriters for such offering exercised
an option to purchase an additional 398,000 shares of Common Stock from the
Company pursuant to such terms to cover over-allotments. The net proceeds to the
Company, less underwriting discounts and other expenses of the offering, totaled
approximately $47,000,000 and were used to pay down amounts outstanding under
the Company's revolving line of credit. The Company's revolving line of credit
has been used to provide working capital, as well as to fund fixed asset and
subsidiary acquisitions.

NOTE 3 -- ACQUISITIONS

     Effective October 1, 1996, the Company acquired all of the outstanding
capital stock of Pipe Shields Incorporated (Pipe Shields), an industrial pipe
insulation company located in Vacaville, California, for approximately
$2,500,000 in cash, net of cash received. The purchase method was used to
account for the acquisition. The excess of cost over the estimated fair value of
the assets acquired (goodwill) was approximately $2,000,000 and is being
amortized on a straight-line basis over 20 years. The operating results of Pipe
Shields have been included in the consolidated statements of income of the
Company from the effective date of the acquisition. The pro-forma effect of the
acquisition of Pipe Shields, had it occurred on September 1, 1996, is not
material to the operations of the Company.

     On January 27, 1997, the Company completed the acquisition of NAPTech,
Inc., a fabricator of industrial piping systems and engineered piping modules
located in Clearfield, Utah. The Company issued 432,881 shares of its Common
Stock in exchange for NAPTech, Inc. and the 335,000 square foot facility that
NAPTech, Inc. had leased from a related entity, Freeport Properties, L.C.
(Freeport). The acquisition was accounted for using the pooling-of-interests
method; accordingly, the Company's financial information for all prior periods

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 5 -- INVESTMENT IN UNCONSOLIDATED ENTITIES

     During the years ended August 31, 1998 and 1999, the Company has not made
any additional investments in Shaw-Nass Middle East, W.L.L., the Company's
Bahrain joint venture (Shaw-Nass). The Company owns 49% of Shaw-Nass and
accounts for this investment on the equity basis. As such, during the years
ended August 31, 1997, 1998, and 1999, the Company recognized earnings (losses)
of $437,000, $(40,000), and $681,000, respectively, from Shaw-Nass. No
distributions have been received through August 31, 1999 from Shaw-Nass. As of
August 31, 1998 and 1999, the Company had outstanding receivables from Shaw-Nass
totaling $1,758,000 and $4,310,000, respectively. These receivables relate to
inventory and equipment sold and net short-term advances to Shaw-Nass. In
addition, at August 31, 1998, the Company had a note receivable from Shaw-Nass
of $436,000 included in other assets.

     During 1997, 1998 and 1999, revenues of $782,000, $1,626,000, and
$1,188,000 were recognized on sales of products from the Company to Shaw-Nass.
The Company's 49% of profit on these sales was eliminated. At August 31, 1999,
undistributed earnings of Shaw-Nass included in the consolidated retained
earnings of the Company amounted to approximately $960,000.

NOTE 6 -- INVESTMENT FOR SECURITIES AVAILABLE FOR SALE

     In connection with its construction services, the Company embarked on its
first significant project financing participation. As a result, the Company
acquired $12,500,000 of 15% Senior Secured Notes (the "Notes") due December 1,
2003, from a customer, together with certain preferred stock related thereto.
The Notes are secured by a first priority security interest in some of the
refinery's assets. The amount and value of the preferred stock is not material.
Through December 1, 2000, additional bonds are expected to be received in lieu
of interest, increasing the Company's investment in the Notes. Since these
securities are available for sale, SFAS No. 115 -- "Accounting for Certain
Investments in Debt and Equity Securities" requires that the securities be
measured at fair value in the balance sheet and that unrealized holding gains
and losses, net of taxes, for these investments be reported in a separate
component of shareholders equity until realized. Based on sales of additional
securities by the debtor during fiscal 1999 and the estimates obtained by the
Company from an investment banking firm, the securities had an aggregate value
approximating the outstanding principal amount of $13,830,000 at August 31,
1999. As a result, no unrealized gain or loss is recognized in shareholders'
equity. Since the financing arrangement is related to construction services, the
interest income of $1,330,000 in 1999 from the Notes is included in sales and
the interest cost of $621,000 in 1999 associated with carrying the Notes is
included in cost of sales in the statement of income. The interest cost was
calculated at the Company's estimated effective borrowing rate of 7%.

     Certain of the debt agreements contain restrictive covenants which the
Company is required to meet including financial ratios and minimum capital
levels among other restrictions. As of August 31, 1999, the Company was in
compliance with the covenants or had obtained the required waivers.

     The estimated fair value of long-term debt as of August 31, 1998 and 1999
was approximately $103,700,000 and $91,712,000 respectively, based on borrowing
rates currently available to the Company for notes with similar terms and
average maturities.

NOTE 8 -- REVOLVING LINES OF CREDIT

     In May 1998, the Company entered into a three-year revolving credit
facility with its U.S. banks, which allows the Company to borrow up to
$100,000,000 at an interest rate not to exceed 2% over the London Interbank
Offering Rate (LIBOR) or .75% over the Prime rate. The index used to determine
the interest rate is selected by the Company and the spread over the index is
dependent upon certain financial ratios of the Company. During fiscal 1998 and
1999, the maximum amount outstanding under the revolving credit facility was
approximately $87,873,000 and $80,532,000 respectively, and the average amount
outstanding was approximately $51,523,000 and $55,006,000 respectively, at
weighted average interest rates of 7.19% and 6.53% respectively. The revolving
credit facility ranks in pari passu with the

Company's Senior Secured Notes and is secured by the Company's domestic accounts
receivable, inventory, intangible assets and bank deposits, as well as by the
pledge of the capital stock of certain of the Company's domestic subsidiaries.

     In September 1999, the Company's revolving credit facility was amended to
extend the expiration date to May 31, 2002. The amendment also modified the
interest rate spread, not to exceed 2.50% over the London Interbank Offering
Rate (LIBOR) or 1.75% over the Prime rate, and certain financial covenants and
ratios.

     In 1998, a foreign subsidiary of the Company initiated an overdraft credit
facility with a bank for up to L3.0 million ($4.9 million), with interest at the
bank's base rate plus 1.25%. The facility is secured by the assets of the
subsidiary and a L10.0 million ($16.3 million) limited guarantee given by the
Company. The facility expired December 17, 1998 and was extended for one year in
January 1999. The extension reduced the facility to L2.0 million ($3.3 million)
at the same interest rate spread as the previous facility. The outcome of the
negotiations to renew or replace this overdraft credit facility is not expected
to have any material adverse effect on the future operations of the Company.

</TABLE>

     As of August 31, 1999, for Federal income tax return purposes, the Company
had approximately $1,900,000 of U.S. net operating loss carryforwards available
to offset future taxable income of its Connex subsidiary. The carryforwards
expire beginning in 2011 through 2013. As of August 31, 1999, the Company's
United Kingdom operations had net operating loss carryforwards of approximately
L1.6 million, ($2.6 million), which can be used to reduce future taxable income
in the United Kingdom. As of August 31, 1999, no benefit had been given to these
losses in the accompanying financial statements due to the current operating
environment in that market. Therefore, a valuation allowance is provided for
these loss carryforwards.

     Unremitted foreign earnings reinvested abroad upon which deferred income
taxes have not been provided aggregated approximately $7,000,000 at August 31,
1999. Due to the timing and circumstances of repatriation of such earnings, if
any, it is not practicable to determine the unrecognized deferred tax liability
relating to such amounts. Withholding taxes, if any, upon repatriation would not
be significant.

NOTE 10 -- COMMON STOCK

     The Company has one class of common stock. Each outstanding share of common
stock which has been held for four consecutive years entitles its holder to five
votes on each matter properly submitted to the Company's shareholders for their
vote, waiver, release or other action. Each outstanding share of common stock
which has been held for less than four consecutive years entitles its holder to
only one vote. Also, the Board of Directors is authorized to approve the
issuance of preferred stock.

     The Company enters into short-term lease agreements for equipment needed to
fulfill the requirements of specific jobs. Any payments owed or committed under
these lease arrangements as of August 31, 1999 are not included as part of total
minimum lease payments. Rent expense for the fiscal years ended August 31, 1997,
1998 and 1999 was $3,587,000, $7,902,000 and $8,297,000, respectively.

NOTE 12 -- COMMITMENTS AND CONTINGENCIES

     In the normal course of business activities, the Company enters into
contractual agreements with customers for certain construction services to be
performed based on agreed upon reimbursable costs and labor rates. In some
instances, the terms of these contracts provide for the customer's review of the
accounting and cost control systems to verify the completeness and accuracy of
the reimbursable costs invoiced. These reviews could result in proposed
reductions in reimbursable costs and labor rates previously billed to the
customer. The Company does not believe that any such reviews will result in a
material change to the Company's financial position or results of operations.

     The Company has posted letters of credit aggregating approximately
$5,600,000 as of August 31, 1999 to secure its performance under certain
contracts and insurance arrangements.

     During 1998 and 1999, the Company was self-insured for workers'
compensation claims in certain states up to certain policy limits. Claims in
excess of $250,000 per incident are insured by third party reinsurers. The
Company has accrued a liability for outstanding and incurred, but not reported,
claims based on historical experience totaling approximately $780,000 and
$821,000 at August 31, 1998 and 1999, respectively.

     During 1998 and 1999, certain subsidiaries of the Company were self-insured
for health claims up to certain policy limits. Claims in excess of $125,000 per
incident and approximately $10,000,000 in the aggregate per year are insured by
third party reinsurers. The Company had accrued a liability of $812,000 and
$1,198,000, respectively, for outstanding and incurred, but not reported, claims
based on historical experience.

     In connection with the acquisition of the principal operating businesses of
Prospect (see Note 3 of Notes to Consolidated Financial Statements), the Company
entered into several indemnification agreements in favor of Prospect, PEL, and
Prospect's principal lender (the Lender). The first agreement required the
Company to indemnify the Lender for any losses that the Lender may incur in
connection with certain letters of credit, bonds and guarantees previously
issued by the Lender relating to projects entered into by PEL, Connex, CBP,
Aiton Australia and other subsidiaries of Prospect. The Company has

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

determined that its exposure for indemnity under the agreement with the Lender
as of August 31, 1999 was approximately $400,000.

     Additionally, the Company has agreed to indemnify each of Prospect, PEL and
the Lender with respect to certain preferential creditors of Prospect and PEL.
Immediately after the closing of the acquisition by the Company of Prospect, the
Lender had an administrative receiver appointed for Prospect, PEL and the
subsidiaries not acquired by the Company. The Company is obligated to indemnify
Prospect and PEL for preferential debts of PEL and Prospect in connection with
the receivership proceedings. Further, the Company has agreed to indemnify the
Lender for any loss the Lender may suffer as a result of the Company's failure
to perform its indemnity obligations under the Company's agreement with Prospect
and PEL concerning preferential creditors. As of August 31, 1999, the Company
estimates the aggregate preferential debt of Prospect and PEL to be
approximately $3,800,000; this amount is included in accrued liabilities in the
accompanying financial statements.

     In the normal course of its business, the Company becomes involved in
various litigation matters including, among other things, claims by third
parities for alleged property damages, personal injuries, and other matters.
While the Company believes it has meritorious defenses against these claims,
management has used estimates in determining the Company's potential exposure
and has recorded reserves in its financial statements related thereto where
appropriate. It is possible that a change in the Company's estimates of that
exposure could occur, but the Company does not expect such changes in estimate
costs will have a material effect on the Company's financial position or results
of operations.

NOTE 13 -- BUSINESS SEGMENTS, OPERATIONS BY GEOGRAPHIC REGION AND MAJOR
CUSTOMERS

 Business Segments

     The Company adopted Statement of Financial Accounting Standards No. 131
("SFAS 131"), Disclosures about Segments of an Enterprise and Related
Information," as of August 31, 1999. SFAS 131 establishes standards for the way
public business enterprises report information about operating segments in
annual financial statements and requires those enterprises to report selected
information about operating segments in interim financial reports issued to
shareholders. It also establishes standards for related disclosures about
products and services, geographic areas and major customers. SFAS 131 defined
operating segments as components of an enterprise about which separate financial
information is available that is evaluated regularly by the chief operating
decision maker in deciding how to allocate resources and in assessing
performance. The Company has aggregated its business activities into two
operating segments: pipe services and manufacturing.

     The pipe services segment of the Company supplies integrated systems,
products and services for piping systems, primarily for the power generation,
chemical processing, crude oil refining, petrochemical processing, oil and gas
exploration and production and other industries. As a "total piping resource",
the Company also offers comprehensive design and engineering services related to
piping systems and pipe support fabrication and manufacturing, and final on-site
erection, turnkey construction and piping project maintenance.

     The manufacturing segment offers its capabilities primarily to the power
generation, chemical processing, crude oil refining, petrochemical processing,
oil and gas exploration and production and other industries, including the pulp
and paper, and food processing industries, by manufacturing and distributing
specialty stainless, alloy and carbon steel pipe fittings. These fittings
include stainless and other alloy elbows, tees, reducers and stub ends. The
Company has one manufacturing facility which distributes its products to the
pipe services segment of the Company enhancing the Company's piping package, as
well as to third parties. The Company also has several distribution centers in
the United States, which distribute its products primarily to third parties.

     Sales are attributed to geographic regions based on location of customer.
Long-lived assets include all long-term assets except those specifically
excluded under SFAS No. 131, such as deferred income taxes and securities
available for sale.

 Information about Major Customers

     The Company's customers are principally major multi-national engineering
and construction firms, equipment manufacturers and industrial corporations. For
the year ended August 31, 1997, no one customer represented more than 10% of
sales. For the year ended August 31, 1998, sales to one customer totaled $51.7
million, or 10% of sales. For the year ended August 31, 1999, sales to a
different customer were $67.7 million, or 14% of sales.

 Export Sales

     For the years ended August 31, 1997, 1998 and 1999, the Company has
included as part of its international sales approximately $89 million, $111
million and $60 million, respectively, of exports from its domestic facilities.

NOTE 14 -- EARNINGS PER COMMON SHARE

     In 1997, the Financial Accounting Standards Board issued Statement of
Accounting Standards (SFAS) No. 128, "Earnings Per Share." SFAS No. 128 replaced
the previously reported primary and fully-diluted earnings per share with basic
and diluted earnings per share.

     Basic earnings per common share were computed by dividing net income by the
weighted average number of shares of common stock outstanding during the year.
Diluted earnings per common share were

determined on the assumptions that all dilutive stock options (see Note 15 of
Notes to Consolidated Financial Statements) were exercised and stock was
repurchased using the treasury stock method, at the average price for each year.
The Company adopted SFAS No. 128 effective December 15, 1997. The following

</TABLE>

     At August 31, 1997, 1998 and 1999, the Company had dilutive stock options
of 427,003, 343,905, and 1,188,500 respectively, which were assumed exercised
using the treasury stock method. The resulting net effect of stock options was
used in the calculation of diluted income per common share for each period.
Additionally, the Company had 28,341, 74,341, and 53,000 of stock options at
August 31, 1997, 1998 and 1999, respectively, which were excluded from the
calculation of diluted income per share because they were antidilutive.

NOTE 15 -- EMPLOYEE BENEFIT PLANS

     The Company has a Stock Option Plan (the Plan) under which both qualified
and non-qualified options and restricted stock may be granted. As of August 31,
1999, 1,645,000 shares of common stock are reserved for issuance under the Plan.
The Plan is administered by a committee of the Board, which selects persons
eligible to receive options and determines the number of shares subject to each
option, the vesting schedule, the exercise price, and the duration of the
option. The exercise price of any option granted under the Plan cannot be less
than 100% of the fair market value on the date of grant and its duration cannot
exceed 10 years. Only qualified options have been granted under the Plan.

     Shares of restricted stock are subject to risk of forfeiture during the
vesting period. Restrictions related to these shares and the restriction terms
are determined by the committee. Holders of restricted stock have the right to
vote the shares. During the year ended August 31, 1998, the Company issued
30,000 shares of restricted stock which had a weighted average grant-date fair
value of $19.38. During fiscal 1999, 15,000 shares were cancelled, and at August
31, 1999, 15,000 shares remain outstanding.

     In connection with the Company's acquisition of FCI and PSSI during 1994,
options to acquire 5,000 shares with an exercise price of $18.00 were issued. In
January 1995, the exercise price of these options was amended to $5.875 per
share, which was the fair market value of the common stock at the date of such
amendment. These options were exercised in 1998. In addition, in 1994 the
Company granted options contingent upon the ability of FCI, PSSI and certain
other subsidiaries to generate consolidated

net income in excess of certain thresholds during the fiscal years ended August
31, 1995, 1996 and 1997. The maximum number of shares related to these options
issuable under this plan was 19,000 per year or 57,000. These options expire in
2004 and have an exercise price equal to the closing price quoted on the last
business day of the immediately preceding fiscal year to which the grant of
options relate. The minimum threshold for the year ended August 31, 1995 was not
met, and therefore, no options were issued for that year. For the year ended
August 31, 1996, options to acquire 12,000 shares with an exercise price of
$9.59 per share were earned and subsequently issued. For the year ended August
31, 1997, options to acquire an additional 12,000 shares with an exercise price
of $32.875 were earned and were issued in fiscal 1998.

     In fiscal 1997, the Company adopted a Non-Employee Director Stock Option
Plan. Each member of the Board of Directors who is not, and who has not been
during the one year period immediately preceding the date the director is first
elected to the Board, an officer or employee of the Company or any of its
subsidiaries or affiliates, is eligible to participate in the Plan. A committee
of two or more members of the Board who are not eligible to receive grants under
the Option Plan administers the Plan. Upon adoption, options to acquire an
aggregate of 20,000 shares of Common Stock were issued. Additionally, each
eligible director will be granted an option to acquire 1,500 shares of Common
Stock on an annual basis upon his election or re-election to the Board of
Directors. An aggregate of 50,000 shares of Common Stock have been reserved for
issuance under the Option Plan.

     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation," (SFAS No. 123) which is effective for the Company's fiscal year
beginning September 1, 1996. Under SFAS No. 123, companies can either record
expense based on the fair value of stock-based compensation upon issuance or
elect to remain under the APB 25 method whereby no compensation cost is
recognized upon grant if certain requirements are met. The Company has elected
to continue to account for its stock-based compensation under APB 25. However,
pro-forma disclosures, as if the Company adopted the cost recognition
requirements under SFAS No. 123, are presented below.

     Had compensation cost been determined based on the fair value at the grant
date consistent with the provisions of SFAS No. 123, the Company's net income
and earnings per common share would have approximated the pro-forma amounts
below:

     As of August 31, 1997, 1998 and 1999, the number of shares relating to
options exercisable under the stock option plans was 160,344; 191,996; and
262,750, respectively, and the weighted average exercise price of those options
was $10.023, $20.608 and $9.324, respectively.

     The weighted average fair value at date of grant for options granted during
1997, 1998 and 1999 was $12.72, $13.21 and $5.23 per share, respectively. The
fair value of options granted is estimated on the date of grant using the
Black-Scholes option-pricing model with the following weighted average
assumptions in 1997, 1998 and 1999, respectively: (a) dividend yield of 0.00%,
0.00% and 0.00%; (b) expected volatility of 54%, 59% and 65% (c) risk-free
interest rate of 6.7%, 5.8% and 5.1%; and (d) expected life of 5 years, 5 years
and 5 years.

     During 1994, the Company, excluding NAPTech, adopted a voluntary 401(k)
profit sharing plan for substantially all employees who are not subject to
collective bargaining agreements. The plan provides for the eligible employee to
contribute from 1% to 15% of annual compensation, subject to an annual limit,
with the Company matching 50% of the employee's eligible contribution up to 6%.
The Company's expense for this plan during 1997, 1998 and 1999 was approximately
$480,000, $813,000 and $1,278,000, respectively.

     The Company has a qualified, contributory 401(k) savings plan covering all
employees of NAPTech who belong to the Certified Metal Trades Journeymen
collective bargaining unit. The Company is required to make a contribution of 3%
of participants' compensation on an annual basis. The Company's expense for this
plan was approximately $52,000, $61,000 and $18,000 for the years ended August
31, 1997, 1998 and 1999, respectively.

     The Company has a defined benefit pension plan for employees of Connex.
Effective January 1, 1994, no new participants were admitted to the plan. The
pension plan's benefit formulas generally base payments to retired employees
upon their length of service and a percentage of qualifying compensation during
their final year of employment. The pension plan's assets are invested in fixed
income assets, equity based mutual funds, and money market funds. At August 31,
1999, the fair market value of the plan assets was $1,509,000, which exceeded
the estimated projected benefit obligation.

     The Company has two pension plans (Plan A and Plan B) for employees of one
of its United Kingdom subsidiaries. Plan A is a money purchase plan in which the
employer and employee make matching contributions between 3% and 6% of
employees' salaries depending on age. From date of acquisition through August
31, 1998, the Company's expense for this plan was $98,000. For the year ended
August 31, 1999, the expense was $78,000. Plan B is a salary-related plan for
certain employees; admittance to this plan is now closed. The employees in Plan
B contribute 7%. The Company contribution depends on length of service, the
employee's salary at retirement, and the earnings of the fund investments. If
the plan's earnings are sufficient, the Company makes no contributions. From the
date of acquisition to August 31, 1998 the Company expensed $111,000 for this
plan. For the year ended August 31, 1999, the Company reflected a credit of
$18,000. The following table sets forth Plan B's pension cost from the date of
acquisition (November 14, 1997) to August 31, 1999, and the plan's funded status
as of August 31, 1998 and 1999 in accordance with the provisions of Statement of
Financial Accounting Standards No. 132 -- "Employers' Disclosure about Pensions
and Other Postretirement Benefits":

     The Company contributes to a Group Employee superannuation fund for its
employees in Australia. This fund is a defined contribution fund with both
employees and the Company contributing a fixed percentage of salary each week.
The Company also contributes to Industry Funds for its employees. These Funds
are also defined contribution funds with the Company contributing a fixed amount
each week for each employee. All members are entitled to benefits on termination
due to retrenchment, retirement, death or disability. The Company is under no
obligation to make up any shortfall in the funds assets to meet payments due to
employees. From the date of acquisition to August 31, 1998, the Company expensed
$139,000 (US dollars) for this plan. For the year ended August 31, 1999, the
Company expensed $82,000 (US dollars) for this plan.

NOTE 16 -- RELATED PARTY TRANSACTIONS

     During 1994, the Company entered into an employment agreement with the
President and Chief Executive Officer (CEO) of the Company. Under terms of the

                      THE SHAW GROUP INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The Company has entered into several loan agreements with key management,
some of which were non-interest bearing. The impact of discounting such loans to
record interest income was not significant. The balance of these employee loan
receivables as of August 31, 1997, 1998, and 1999 was approximately $416,000,
$996,000 and $1,579,000, respectively. These balances are included in other
assets.

     During 1996 and 1997, in connection with certain acquisitions discussed in
Note 3, the Company has entered into non-competition agreements with several key
employees. Related assets totaling approximately $930,000 (net of accumulated
amortization of $1,338,000) are included in other assets and is being amortized
over five to eight years using the straight-line method. Any corresponding
liabilities are included in long-term debt as further discussed in Note 7 of
Notes to Consolidated Financial Statements.

     A director of the Company was a managing director of the investment banking
firm that was an underwriter and acted as one of the representatives of the
underwriters for the public offering of 2,000,000 shares of Common Stock
discussed in Note 2 of Notes to Consolidated Financial Statements. The Company
also granted to the underwriters an option to purchase up to an additional
398,000 shares of Common Stock pursuant to such terms to cover over-allotments,
which over-allotment option was exercised. The closing of such public offering
was completed in December 1996 and January 1997, at a price of $21.00 per share,
less the underwriting discounts and commissions of approximately $2,500,000.
Approximately 40% of these commissions were earned by the director's investment
banking firm. In connection with this public offering, certain officers and
directors of the Company sold 494,118 shares of stock. The same investment
banking firm handled the repurchase of some of the shares of the Company's
common stock which began in fiscal 1999, earning $74,330 in commissions.

     A director of the Company is an owner of construction companies that were
used primarily as a sub-contractor by the Company. During fiscal 1998, the
Company paid these construction companies approximately $4,000,000 for work
performed. During fiscal 1999, payments to these construction companies was not
material.

     In connection with the acquisition of a subsidiary in fiscal 1998, the
Company financed $1,078,000 of the purchase with two of the former owners, who
are now employees of the Company. This debt was paid off in 1999.

NOTE 17 -- FOREIGN CURRENCY TRANSACTIONS

     The Company's wholly-owned subsidiaries in Venezuela had net assets of
approximately $16,300,000 and $16,700,000 denominated in Venezuelan Bolivars as
of August 31, 1998 and 1999, respectively. In accordance with SFAS 52, "Foreign
Currency Translation," the U.S. dollar is used as the functional reporting
currency since the Venezuelan economy is defined as highly inflationary.
Therefore, the asset and liabilities must be translated into U.S. dollars using
a combination of current and historical exchange rates.

     During 1996, the Venezuelan government lifted its foreign exchange
controls. Subsequent to this action, the Bolivar devalued from 170 to 620 (at
August 31, 1999) to the U.S. dollar. During 1998 and 1999, the Company recorded
losses of approximately $734,000 and $652,000 respectively, in translating the
assets and liabilities of its Venezuelan subsidiaries into U.S. dollars. Because
these losses were partially offset by inflationary billing provisions in certain
Company contracts, the $734,000 and $652,000 were offset against sales.

     Other foreign subsidiaries maintain their accounting records in their local
currency (primarily British Sterling, Australian Dollar and Dutch Guilder). The
currencies are converted to U.S. dollars with the effect of the foreign currency
translation reflected in "accumulated other comprehensive income," a component
of shareholders' equity, in accordance with SFAS No. 52 and SFAS No
130 -- "Reporting Comprehensive Income." Foreign currency transaction gains or
losses are credited or charged to income. There were no material transaction
gains or losses incurred in fiscal 1997. At August 31, 1998 and 1999

respectively, cumulative foreign currency translation adjustments related to
these subsidiaries reflected in shareholders' equity amounted to $420,000 and
$1,535,000; transaction gains reflected in income amounted to $32,000 and
$119,000.

     At August 31, 1998 and 1999, the Company's subsidiaries in the United
Kingdom had net assets of approximately $12,100,000 and $13,900,000; the
Company's subsidiary in Australia had net assets of approximately $1,300,000 and
$900,000; and the Company's subsidiary in the Netherlands had net assets of
approximately $9,600,000 and $9,100,000, respectively.

NOTE 18 -- DISCONTINUED OPERATIONS

     In June 1998, the Company adopted a plan to discontinue its operations of
the following subsidiaries: Weldtech, a seller of welding supplies; Inflo
Control Systems Limited (Inflo), a manufacturer of boiler steam leak detection,
acoustic mill and combustion monitoring equipment and related systems; Greenbank
(a division of PEL), an abrasive and corrosion resistant pipe systems
specialist; and NAPTech Pressure Systems Corporation, a manufacturer of pressure
vessels and truck tanker trailers. The Company sold and/or discontinued its
investment in each of these operations prior to August 31, 1998. Proceeds from
the sale of these operations totaled approximately $1,200,000 in net cash and
notes receivable of approximately $7,400,000, which resulted in a net gain on
the disposal of $2,647,000, net of tax. The results of these operations have
been classified as discontinued operations in the consolidated financial
statements of the Company. Revenues of these discontinued operations totaled
approximately $2,600,000 and $7,700,000 in 1997 and 1998, respectively.
