ITEM 1. BUSINESS.

GENERAL

     TransCoastal Marine Services, Inc. ("TCMS") is a marine construction
company with operations focused in the transition zone (water depths up to 20
feet) and shallow water (from 20 to 200 feet) in the Gulf of Mexico. The
Company's primary services include pipeline construction, repair, maintenance,
trenching, testing, commissioning and related services, and fabrication and
refurbishment of offshore drilling rigs, barge drilling rigs and structural
components of fixed platforms.

     TCMS commenced operations concurrently with the acquisition (the
"Acquisitions") of four privately owned marine construction businesses (each a
"Founding Company") and the completion of an initial public offering in November
1997 (the "Offering"). Unless otherwise indicated by the context, references
herein to (i) "TCMS" mean TransCoastal Marine Services, Inc. (and its
predecessor), prior to consummation of the Acquisitions, and (ii) the "Company"
mean TCMS (and its predecessor), together with the Founding Companies and its
other subsidiaries.

     The Company currently conducts operations from port facilities and
fabrication yards strategically positioned along the U.S. Gulf Coast. The
Company's principal executive offices are located at 2925 Briarpark Drive, Suite
930, Houston, Texas 77042, and its telephone number is (713) 784-7429.

OPERATIONS

     Pipeline Installation and Repair. The efficient development of an offshore
oil and gas field frequently involves the addition or extension of an
infrastructure of gathering lines and trunklines (large diameter pipelines). The
Company's pipeline installation operations are focused on the transition zone
and shallow water regions along the U.S. Gulf Coast. The Company believes it is
the only company providing pipeline installation and repair services from water
depths of 200 feet through the transition zone and to onshore gathering and
processing facilities in the Gulf of Mexico.

     The Company's fleet includes (i) 15 spud barges and ancillary equipment,
operated in water depths of up to 20 feet, and (ii) three anchor barges and
three multipurpose vessels (used in both pipeline installation and repair and
hydrostatic testing, commissioning and related operations), primarily operated
in water depths beyond 20 feet. The Company also owns specialized equipment for
offshore pipeline jetting (a specialized pipeline burying technique) and testing
services, marine dredging and trench digging. See Item 2. Properties for a
listing of the Company's significant vessels and equipment.

     Hydrostatic Testing and Commissioning Services. The Company performs
onshore and offshore hydrostatic testing and commissioning of pipelines for oil
and gas producers and pipeline construction companies along the U.S. Gulf Coast
and in certain international markets. During hydrostatic testing, water is
pumped into a newly installed or existing pipeline to increase the internal
pressure beyond the designed capacity of the pipeline in order to test its
structural integrity. Pipeline commissioning involves final preparation of a
completed and successfully tested pipeline for operation in accordance with
applicable regulatory standards. In connection with its hydrostatic testing and
commissioning services, the Company also performs pipeline cleaning, drying and
dehydration services.

     Offshore Fabrication. The Company fabricates and refurbishes (i) structural
components of fixed platforms for use in the offshore development and production
of oil and gas and (ii) structural components, primarily deck structures, for
offshore drilling rigs and barge drilling rigs. The Company also manufactures
amphibious undercarriages for marine construction equipment used in transition
zone waters.

INDUSTRY OVERVIEW

     The market for offshore pipeline installation and related services along
the U.S. Gulf Coast is primarily dependent on the levels of oil and gas
exploration, development and production activities and pipeline capacity
utilization in the Gulf of Mexico. The Company believes recent increases in oil
and gas production in the Gulf

                                        1
<PAGE>   4

of Mexico have significantly reduced available pipeline capacity to transport
the hydrocarbons to onshore gathering, transmission and processing facilities.
In a report published in January 1997, the Minerals Management Service of the
U.S. Department of the Interior (the "MMS") projected an increase in Gulf of
Mexico oil production of up to 76% from 1,097 Mbpd (thousand barrels per day) in
1996 to 1,932 Mbpd by 2000, and an increase in natural gas production of up to
25% from 13.8 Bcfd (billion cubic feet per day) in 1996 to 17.2 Bcfd by 2000,
assuming increased use of new technologies, such as 3-D seismic and horizontal
drilling techniques, would offset declines in production from currently
producing fields. This outlook is supported by increases in offshore leases
awarded by the Department of the Interior in its semi-annual Outer Continental
Shelf ("OCS") lease auctions during 1996. The number of offshore leases awarded
to operators increased from 202 in 1992, covering approximately 1.0 million
acres, to 1,508 in 1996, covering approximately 8.0 million acres.

     The MMS anticipates that a substantial portion of the increased oil and gas
production in the Gulf of Mexico will come from deep water projects. The Company
believes the continued development of deep water (depths of 200 feet to 1,000
feet) and very deep water (depths of 1,000 feet and deeper) oil and gas fields
will require construction of new pipelines and tie-ins to existing pipeline
systems in the transition zone and shallow water regions along the U.S. Gulf
Coast to transport future hydrocarbon production to shore. The Company also
expects increases in demand for its services resulting from new pipeline
construction needed to support incremental development activity within these
transition zone and shallow water regions, as well as the repair service
requirements of the existing pipeline infrastructure. According to a June 1997
report by Offshore Data Services, Inc., there were 255 pipeline construction
projects in the design or planning phase in the Gulf of Mexico, including 165 in
water depths of less than 150 feet.

MATERIALS

     The principal materials used by the Company in its business are carbon and
alloy steel in various forms, welding supplies, fuel oil, gasoline and paint,
which are currently available in adequate supply from many sources. The Company
does not depend on any single supplier or source. Pipe used in the Company's
pipeline construction operations is generally provided by the Company's
customers.

SAFETY AND QUALITY ASSURANCE

     Management sets as a high priority the safety and health of the Company's
employees and maintains a stringent safety assurance program to reduce the
possibility of costly accidents. The Company has established guidelines to
ensure compliance with all applicable state and federal safety regulations, and
provides ongoing training and safety education through orientations for new
employees and subcontractors, periodic crew safety training meetings and first
aid and CPR training. The Company has a comprehensive drug testing program and
conducts periodic employee health screenings.

     The Company's operations are conducted in compliance with the applicable
standards of the American Petroleum Institute, the American Welding Society and
the American Society of Mechanical Engineers, as well as customer
specifications. Training programs have been instituted to upgrade the skills of
the Company's personnel and maintain high-quality standards. Management believes
these programs enhance the quality of its services and reduce the total cost of
work performed.

CUSTOMERS AND CONTRACTS

     The Company's primary customers are major and independent oil and gas
exploration and production companies, drilling contractors, hydrocarbon
transportation companies and other marine construction companies. The level of
construction services required by any one customer depends on the amount of that
customer's capital expenditure budget devoted to marine construction in any
single year. Consequently, customers that account for a significant portion of
revenue in one fiscal year may represent an immaterial portion of revenue in
subsequent fiscal years. The five most significant customers of the Company on a
combined basis during fiscal 1997 (in alphabetical order) were: Bridgeline Gas
Distribution L.L.C., Koch Gateway Pipeline Co., Mobil Corporation, Nautilus Pipe
Line Co. L.L.C., and Texaco Trading & Transporta-

                                        2
<PAGE>   5

tion, Inc. The Company had only two customers that represented more than 10% of
its revenues in fiscal 1997. While the Company is not dependent on any one
customer, the loss of one of its significant customers could, at least on a
short-term basis, have an adverse effect on the Company's results of operations.

     The Company's contracts are typically of short duration, being completed in
one to six months. A substantial number of the Company's projects are performed
on a fixed-price basis, although some projects are performed on an
alliance/partnering or cost-plus basis. Under a fixed-price contract, the
Company receives the price fixed in the contract, subject to adjustment only for
change orders placed by the customer. As a result, the Company is responsible
for all cost overruns under fixed-price contracts. Under a typical alliance/
partnering arrangement, the Company and the customer agree in advance to a
target price that includes specified levels of labor and material costs and
profit margins. If the project is completed at less than the cost levels
targeted in the contract, the contract price is reduced by a portion of the
savings. If the cost to completion is greater than targeted costs, the contract
price is increased, but generally to the target price plus the actual
incremental cost of material and direct labor. Accordingly, under an
alliance/partnering arrangement, the Company has some protection against cost
overruns but must share a portion of any cost savings with the customer. Under
cost-plus arrangements, the Company receives a specified fee in excess of its
direct labor and material cost and therefore is protected against cost overruns
but does not benefit directly from cost savings. The revenue, costs and gross
profit realized on a contract will often vary from the estimated amounts on
which such contracts were originally based because of various reasons, including
errors in estimates or bidding, changes in the availability and cost of labor
and material and variations in productivity from the original estimates. These
variations and the risks inherent in the marine construction industry may result
in revenue and gross profits different from those originally estimated and can
result in reduced profitability or losses on projects. Depending on the size of
a project, variations from estimated contract performance can have a significant
impact on the Company's operating results for any particular fiscal quarter or
year.

COMPETITION

     The marine construction services business is highly competitive and in
recent years has been characterized by overcapacity, which has resulted in
substantial pressure on pricing and operating margins. The Company expects the
overcapacity in the industry to reoccur from time to time in the future.
Contracts for marine construction services are usually awarded on a competitive
bid basis. Although the Company believes customers consider, among other things,
the availability and technical capabilities of equipment and personnel,
efficiency, condition of equipment, safety record and reputation, price
competition is currently a primary factor in determining which qualified
contractor with available equipment is awarded a contract. Some of the Company's
competitors are larger and have greater financial and other resources than the
Company.

     The Company categorizes the market for offshore construction services into
four segments: (i) transition zone (less than 20 feet), (ii) shallow water (20
feet to 200 feet), (iii) deep water (200 feet to 1,000 feet) and (iv) very deep
water (1,000 feet or deeper). The Company generally focuses on projects in
transition zone and shallow water regions along the U. S. Gulf Coast. Activity
in these regions has increased significantly in recent years primarily because
of increases in oil and gas production in the Gulf of Mexico. Several companies
that have one or more derrick or pipelaying barges compete in the transition
zone and shallow water regions. The Company believes that it is the largest
transition zone marine construction services company focused on the U.S. Gulf
Coast and a significant provider of shallow water marine construction services
in that area. The Company believes that competition for projects in the deep
water (greater than 200 feet) and the very deep water (greater than 1,000 feet)
regions of the Gulf of Mexico is primarily limited to two large competitors,
Global Industries, Ltd. and J. Ray McDermott, S.A., with several other
international contractors capable of relocating equipment to the Gulf of Mexico
to work on specific deep or very deep water contracts. Because projects in the
deep and very deep water regions involve different vessels and equipment, as
well as different technical expertise, the Company does not presently intend to
compete in those markets.

     The Company also competes with numerous competitors in connection with its
hydrostatic testing and commission services and fabrication operations.

BACKLOG

     As of December 31, 1997, the Company's unfilled contracts and backlog
orders (including verbal orders) amounted to approximately $47.3 million;
however, the Company does not consider its backlog amounts to be a reliable
indicator of future revenue because most of the Company's projects are awarded
and performed within a relatively short period of time. The Company's backlog
fluctuates significantly based on the timing of contract awards and varying
levels of operating activity throughout the year. The Company is generally able
to complete its projects within a 12-month period.

FLUCTUATIONS IN OPERATING RESULTS

     The Company's results of operations may fluctuate significantly from
quarter to quarter or year to year because of a number of factors, including the
timing of future acquisitions, seasonal fluctuations in the demand for marine
construction services (particularly during the winter months) and competitive
factors. Accordingly, quarterly comparisons of the Company's revenue and
operating results should not be relied on as an indication of future
performance, and the results of any quarterly period may not be indicative of
results to be expected for a full year. The Company recognizes most of its
contract revenue on a percentage-of-completion basis. Accordingly, contract
price and cost estimates are reviewed periodically as the work progresses, and
adjustments proportionate to the percentage of completion are reflected in
income in the period when the facts giving rise to a revised estimate become
known. To the extent that these adjustments result in a reduction or elimination
of previously reported profits with respect to a project, the Company would
recognize a charge against current earnings, which could be material. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business -- Customers and Contracts."

GOVERNMENTAL REGULATION AND ENVIRONMENTAL MATTERS

  General

     Many aspects of the Company's operations are subject to governmental
regulation, including regulation by the U.S. Coast Guard, the National
Transportation Safety Board, the U.S. Customs Service and the Occupational
Safety and Health Administration, as well as by private industry organizations
such as the American Bureau of Shipping. The Coast Guard and the National
Transportation Safety Board set safety standards and are authorized to
investigate vessel accidents and recommend improved safety standards relating to
vessels. The Occupational Safety and Health Administration performs similar
functions with respect to the Company's onshore facilities and operations. In
addition, the Company depends on the demand for its services from the oil and
gas industry and, therefore, the Company's business is affected by the laws and
regulations, as well as changing taxes and governmental policies, relating to
the oil and gas industry generally.

     Certain of the Company's barges and vessels are subject to safety and
classification standards imposing requirements for periodic inspections and the
maintenance of certain certificates and insurance coverages, generally depending
on the type and size of and service performed by the barge or vessel. In
addition, in order for a vessel to engage in the U.S. Coastwise Trade (providing
transportation services between the states), the vessel must have been built in
the United States. All the Company's barges and vessels are eligible for service
in the U.S. Coastwise Trade, except for the M/V Discovery, a Panamanian flagged
vessel. As a multi-purpose construction vessel providing non-transportation
services to the offshore oil and gas industry, the Company believes the market
for the services performed by the M/V Discovery is not materially limited by its
Panamanian registration.

     The Company is required by various governmental and quasi-governmental
agencies to obtain certain permits, licenses and certificates with respect to
its operations. The Company believes that it has obtained all permits, licenses
and certificates necessary to the conduct of its business.

     In addition to government regulation, various private industry
organizations, such as the American Petroleum Institute, the American Society of
Mechanical Engineers and the American Welding Society, promulgate technical
standards that must be adhered to during the course of the Company's fabrication
operations.

                                        4

  Environmental

     The operations of the Company are also affected by numerous federal, state
and local laws and regulations relating to protection of the environment. The
requirements of these laws and regulations have become more complex, stringent
and expensive in recent years, and may, in certain circumstances, impose strict
liability, rendering a company liable for environmental damages and remediation
costs without regard to negligence or fault on the part of such party. Aside
from possible liability for damages and costs associated with releases of
hazardous materials including oil into the environment, such laws and
regulations may expose the Company to liability for the conduct of or conditions
caused by others or acts of the Company that were in compliance with all
applicable laws at the time such acts were performed. Sanctions for
noncompliance with these laws and regulations may include revocation of permits,
corrective action orders, administrative or civil penalties, and criminal
prosecution. The Company is not aware of any noncompliance with applicable
environmental laws and regulations that would likely have a material adverse
effect on the Company's business or financial conditions, and the Company does
not currently anticipate any material adverse effect on its business or
consolidated financial position as a result of future compliance with existing
environmental laws and regulations controlling the discharge of materials into
the environment or otherwise relating to the protection of the environment.
However, it is possible that changes in the environmental laws and regulations
and enforcement policies thereunder, or claims for damages to persons, property,
natural resources or the environment could result in substantial costs and
liabilities to the Company, and thus there can be no assurance that the Company
will not incur significant environmental compliance costs in the future. The
Company's insurance policies provide liability coverage for sudden and
accidental occurrences of pollution and cleanup and containment of the foregoing
in amounts the Company believes are comparable to policy limits carried by other
construction contractors in the offshore industry.

     The Oil Pollution Act of 1990 ("OPA"), as amended, and regulations
promulgated pursuant thereto impose a variety of regulations on "responsible
parties" related to the prevention of oil spills and liability for damages
resulting from such spills. A "responsible party" includes the owner or operator
of an onshore facility, pipeline, or vessel, or the lessee or permittee of the
area in which an offshore facility is located. The OPA assigns liability to each
responsible party for oil removal costs and a variety of public and private
damages. Vessels subject to OPA other than tank vessels are subject to liability
limits of the greater of $500,000 or $600 per gross ton. A party cannot take
advantage of liability limits if the spill was caused by gross negligence or
willful misconduct or resulted from violation of a federal safety, construction,
or operating regulation. If the party fails to report a spill or to cooperate
fully in the cleanup, the liability limits likewise do not apply. Few defenses
exist to the liability imposed under OPA. The OPA also imposes ongoing
requirements on a responsible party including preparation of an oil spill
contingency plan and proof of financial responsibility (to cover at least some
costs in a potential spill) for vessels in excess of 300 gross tons. The Company
believes that it currently has in place appropriate spill contingency plans and
has established adequate proof of financial responsibility for its vessels.

     The Outer Continental Shelf Lands Act ("OCSLA") provides the federal
government with broad discretion in regulating the release of offshore resources
of oil and gas production. Because the Company's operations rely on offshore oil
and gas exploration and production, if the government were to exercise its
authority under OCSLA to restrict the availability of offshore oil and gas
leases, such an action could have a material adverse effect on the Company's
financial condition and the results of operations.

     The Comprehensive Environmental Response, Compensation, and Liability Act
of 1980 ("CERCLA"), as amended, and comparable state laws impose liability for
releases of hazardous substances into the environment. CERCLA currently exempts
crude oil from the definition of hazardous substances for purposes of the
statute, but the Company's operations may involve the use or handling of other
materials that may be classified as hazardous substances. CERCLA assigns strict
liability to each responsible party for all response and remediation costs, as
well as natural resource damages. Few defenses exist to the liability imposed by
CERCLA. The Company believes that it is in compliance with CERCLA and currently
is not aware of any events that, if brought to the attention of regulatory
authorities, would lead to the imposition of CERCLA liability against the
Company.

  Health and Safety

     The Company's operations are also governed by laws and regulations relating
to workplace and worker health, primarily the Occupational Safety and Health Act
and the regulations promulgated thereunder. In addition, various other
governmental and quasi-governmental agencies require the Company to obtain
certain permits, licenses and certificates from time to time with respect to its
operations. The Company believes it has all material permits, licenses and
certificates necessary to the conduct of its existing business.

     Certain employees of the Company are covered by provisions of the Jones
Act, the Death on the High Seas Act and general maritime law, which laws operate
to make the liability limits established by state workers' compensation laws
inapplicable to these employees and, instead, permit them or their
representatives to pursue actions against the Company for damages or job-related
injuries, with generally no limitations on the Company's potential liability.
The Company's ownership and operation of vessels can give rise to large and
varied liability risks, such as risks of collisions with other vessels or
structures, sinking, spills, fires and other marine casualties, which can result
in significant claims for damages against both the Company and third parties
for, among other things, personal injury, death, property and natural resource
damage, pollution and loss of business.

RISK MANAGEMENT

     The Company's operations are subject to inherent risks of offshore and
inland marine activity, including hazards such as vessels capsizing, sinking,
grounding, colliding and sustaining damage from severe weather conditions. These
hazards can cause personal injury or loss of life, severe damage to and
destruction of property and equipment, pollution or environmental damage and
suspension of operations. The Company maintains such insurance protection as it
deems prudent, including hull insurance. However, certain risks are either not
insurable or insurance is available only at rates that the Company considers not
to be economical. There can be no assurance that any such insurance will be
sufficient or effective under all circumstances or against all hazards to which
the Company may be subject. A successful claim for which the Company is not
fully insured could have a material adverse effect on the Company. Moreover, no
assurance can be given that the Company will be able to maintain adequate
insurance in the future at rates it considers reasonable.

INTELLECTUAL PROPERTY

     Although the Company's intellectual property rights are, in the aggregate,
important to the Company's business, the Company believes its technical
knowledge and experience, reputation and customer relationships are more
important to its competitive position than any patents, licenses, trademarks or
other intellectual property rights.

EMPLOYEES

     The size of the Company's work force, other than its clerical and
administrative personnel, is variable and depends on the Company's workload at
any particular time. As of February 28, 1998, the Company had approximately 758
employees. In addition, many workers are hired on a contract basis and are
available to the Company on short notice. None of the Company's employees are
covered by a collective bargaining agreement.

FORWARD-LOOKING STATEMENTS

     The Annual Report on Form 10-K includes certain statements that may be
deemed to be "forward-looking statements" within the meaning of Section 27A of
the Securities Act of 1933, as amended, and Section 21E of the Securities
Exchange Act of 1934. All statements other than statements of historical facts,
included in this Annual Report on Form 10-K that relate to business plans or
strategies, projected or anticipated benefits or other consequences of such
plans or strategies, projected or anticipated benefits from acquisitions made by
or to be made by the Company, or projections involving anticipated revenues,
earnings, or other aspects of operating results are forward-looking statements.
The Company cautions readers that such statements are not guarantees of future
performance or events and are subject to a number of factors that may
                                        6
<PAGE>   9

tend to influence the accuracy of the statements and the projections upon which
the statements are based. As noted elsewhere in this report, all phases of the
Company's operations are subject to a number of uncertainties, risks and other
influences, many of which are outside the control of the Company, and any one of
which, or a combination of which, could materially affect the results of the
Company's operations and whether forward-looking statements made by the Company
ultimately prove to be accurate.

ITEM 2. PROPERTIES.

MARINE VESSELS AND EQUIPMENT

     The Company's fleet includes three multi-purpose vessels, three anchor
barges and 15 spud barges. During March 1997, the Company acquired the M/V
Discovery, a multi-purpose Panamanian flagged construction ship, for the purpose
of expanding the capabilities of the Company's offshore pipeline testing
operations. During February 1998, the Company expanded its oil and gas pipeline
installation capabilities with the acquisition of the LB-207 pipelaying barge
(now renamed the Vermilion Bay) from Essar Oil Ltd. The Vermilion Bay is
currently in transport from India and is expected to be available for service in
the Gulf of Mexico by May 1998.

     The following table describes the Company's principal marine vessels and
construction equipment.

FACILITIES

     Administration. The Company owns administrative buildings in Lafayette and
Belle Chasse, Louisiana, and leases office space in New Iberia, Louisiana and in
Houston, Texas.

     Construction Support Facilities. The Company's marine construction
activities are supported by five onshore bases which provide administrative
functions for projects and dock space for the Company's floating equipment with
the ability to supply the vessels with provisions and fuel, and to perform
maintenance and repairs to vessels and equipment. The facility located in Belle
Chasse, Louisiana is owned by the Company. The facilities and dock frontage at
Berwick and Delcambre, Louisiana, and Mobile Bay, Alabama are leased, with
remaining lease terms ranging from month-to-month to 16 years.

     Fabrication Yards. The Company's fabrication operations are primarily
conducted from three locations in Louisiana, one in New Iberia and two in the
greater New Orleans area. The New Iberia fabrication facility includes
approximately 14 acres of leased land and a 23,200 square foot fabrication shop
which is supplied with automatic welding, heavy fabrication and material
handling equipment. This fabrication yard, with waterfront docking and direct,
deep channel access to the Gulf of Mexico, has specially designed concrete
reinforcements and approximately 700 linear feet of water frontage. The Company
is improving the fabrication yard to provide it with the ability to load out
structures weighing up to 5,000 tons. The fabrication yard also has a rail spur,
which provides it direct access to rail transportation.

     During the first quarter of 1998, the Company significantly expanded its
fabrication operations through two separate lease transactions. During January
1998, long-term lease rights were secured to a shipyard in New Orleans capable
of servicing deepwater drilling rigs, jack-ups, semi-submersibles and drill
ships. This 29-acre yard is located at the intersection of the Intracoastal
Waterway and the Michoud Canal. A 32-foot water depth is maintained at the site,
which has no height or width restrictions and a maximum 3,000 feet of bulkhead
dock space. During February 1998, the Company signed a long-term lease for a
manufacturing facility located on an 18-acre site on the Inner Harbor Navigation
Canal in eastern New Orleans. The site has 1,400 feet of waterfront and includes
a covered, 68,000 square foot fabrication shop with eave height exceeding 40
feet and overhead crane capacity totaling 75 tons with a hook height of 28 feet.

     The Company also owns an 18,000 square foot fabrication facility situated
on approximately two acres of land in Lafayette, Louisiana, and has an option to
purchase a 10,000 square foot fabrication facility situated on approximately
five acres of land in Belle Chasse, Louisiana.

ITEM 3. LEGAL PROCEEDINGS.

     The Company is currently involved in two class action lawsuits for
unspecified personal injury and property damages arising from events in October
1991 and January 1992 during the course of a pipeline installation project for a
third party gas transmission company. One of the class actions, involving
approximately 9,840 class members, entitled Rivera v. United Gas Pipeline Co.,
No. 28738, was instituted against Woodson Construction Company, Inc. on October
29, 1991 in the 40th Judicial District Court, Parish of St. John the Baptist,
State of Louisiana, and the other class action, involving approximately 7,858
class members, entitled Husseiney v. United Gas Pipeline Co., No. 29089, was
instituted on January 27, 1992 against Woodson Construction Company, Inc. in the
40th Judicial District Court, Parish of St. John the Baptist, State of
Louisiana. The claims of 24 representative class members in each case were tried
in 1995, and judgments were rendered against Woodson Construction Company, Inc.,
which were later affirmed by the court of appeal. In the Rivera lawsuit, five of
the 24 representative plaintiffs were awarded compensatory damages of $7,500 in
the aggregate, but punitive damages were denied. In the Husseiney lawsuit,
compensatory damages of $18,589 and punitive damages of $9,500 in the aggregate
were assessed against Woodson Construction Company, Inc. in favor of 16 of the
24 representative plaintiffs. In both lawsuits, the compensatory damages awarded
are expected to be covered by the Company's insurance, but punitive damage
awards are not expected to be covered by insurance. The compensatory and
punitive damages awarded to the 16 representative class members varied according
to the representatives' proximity to the incident and individual experience with
respect to it. The amount of compensatory and punitive damages applicable to the
remaining 7,834 class members who seek to adjudicate their damage claims will be
litigated on an individual
                                        8
<PAGE>   11

basis. Until those remaining damage claims are finally adjudicated, settled,
dismissed or otherwise terminated, the total amount of the punitive damages to
which the Company may be subject cannot reasonably be estimated, and there can
be no assurance that it will not be materially adverse to the Company's
financial position or results of operations. In July 1997, all parties involved
applied to the Louisiana Supreme Court for further discretionary review of the
existing judgments. In December 1997, the Louisiana Supreme Court declined to
review the judgments in both cases.

     The Company is involved in various other lawsuits arising in the ordinary
course of business, some of which involve substantial claims for damages. While
the outcome of these other lawsuits cannot be predicted with certainty,
management believes these other matters will not have a material adverse effect
on the consolidated financial position or results of operations of the Company.

</TABLE>

     At March 16, 1998, there were approximately 2,200 stockholders of record of
the Company's Common Stock. On March 16, 1998, the last reported sale price of
the Common Stock on the Nasdaq National Market was $10 5/8 per share.

DIVIDENDS

     TCMS currently intends to retain its earnings, if any, to finance the
expansion of its business and for general corporate purposes, including future
acquisitions, and does not anticipate paying any cash dividends on its Common
Stock for the foreseeable future. Any future dividends will be at the discretion
of the Board of Directors, after taking into account various factors, including,
among others, the Company's financial condition, results of operations, cash
flows from operations, current and anticipated cash needs and expansion plans,
the income tax laws then in effect, the requirements of Delaware law, the
restrictions currently imposed by the Credit Agreement and any restrictions that
may be imposed by the Company's future credit arrangements. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations".

SALE OF UNREGISTERED SECURITIES

     The following information relates to securities of the Company issued or
sold by the Company during the past year which were not registered under the
Securities Act:

          (i) 2,142,441 shares of Common Stock were issued to the Founding
     Companies on closing of the Acquisitions and the initial public offering
     (the "Offering"). Shareholders of the Founding Companies have certain
     registration rights with respect to 1,975,775 shares of Common Stock
     received by them in the Acquisitions, subject to the one-year Lockup Period
     described below; and

          (ii) 1,256,000 shares of Common Stock which were issued to founders of
     TCMS and certain of its executive officers and consultants in conjunction
     with the Offering.

     All of the aforementioned shares, as well as: (1) an aggregate of 50,000
shares issuable pursuant to a warrant (the "MG Warrant") issued by TCMS to
McFarland, Grossman & Company, Inc. ("MGCO"), a financial advisory firm that
assisted the Company in connection with the Acquisitions and in arranging the
Credit Agreement, and (2) an aggregate of 175,000 shares issuable pursuant to a
warrant (the "Lender Warrant") issued by TCMS to Joint Energy Development
Investments, Limited Partnership, an affiliate of Enron Capital & Trade
Resources Corp., in connection with the Credit Agreement, may be resold publicly
only following their effective registration under the Securities Act or pursuant
to an exemption from the registration requirements of that act, such as Rule 144
thereunder.

     At the time of and in conjunction with the Offering, TCMS and its directors
and executive officers, MGCO, J&D Capital Investments, L.C. (which is majority
owned by G. Darcy Klug, a promoter of TCMS), all of TCMS' other current
stockholders and all persons who received shares of Common Stock in connection
with the Acquisitions (other than Common Stock issuable upon exercise of the
Lender Warrant) agreed not

                                       10
<PAGE>   13

to offer or sell any of those shares for a period of one year from October 31,
1997 (the "Lockup Period") without the prior written consent of Jefferies &
Company, Inc., with the following exceptions: the Company may issue Common Stock
in connection with future acquisitions, subject to certain conditions, and
pursuant to awards under the 1997 Stock Option Plan.

ITEM 6. SELECTED FINANCIAL DATA.

     In accordance with the applicable accounting rules of the Securities and
Exchange Commission (the "Commission"), Woodson Construction Company
(collectively with three affiliated companies, "Woodson"), one of the Founding
Companies, has been identified as the "accounting acquiror" for financial
statement presentation purposes. Consequently, the Company's historical
financial statements for periods ended on or before October 31, 1997, the
effective date of the acquisitions of the Founding Companies for accounting
purposes, are the consolidated historical financial statements of Woodson. As
used in this discussion, the "Company" means (i) Woodson prior to October 31,
1997 and (ii) TCMS and its consolidated subsidiaries on that date and
thereafter. The following selected historical financial information has been
derived from the audited financial statements of the Company for each years
presented. The summary financial information below should be read in conjunction
with the historical financial statements and notes thereto included elsewhere
herein.

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

     The following discussion should be read in conjunction with the
consolidated financial statements and related notes thereto and "Selected
Financial Data" appearing elsewhere in this Annual Report on Form 10-K. The
following information contains forward-looking statements. For a discussion of
certain limitations inherent in such statements, see
"Business -- Forward-Looking Statements."

INTRODUCTION

     The Company's revenues are primarily derived from providing services
related to pipeline installation and repair, hydrostatic testing and
commissioning of pipelines, and fabrication and refurbishment of components for
oil and gas production platforms and drilling rigs. To a lesser extent, the
Company generates revenue from (i) the manufacture and sale of amphibious
undercarriages for marine construction equipment used in stump-studded swamp
terrain and (ii) onshore environmental site assessments and on-site remediation
of petroleum-contaminated areas.

     Most of the Company's services are provided under fixed-priced contracts
and are generally completed within one year. These contracts are usually
accounted for using the percentage-of-completion method of accounting. Under
this method, the percentage-of-completion is determined by comparing contract
costs incurred to date with total estimated contract costs. Any significant
revision in cost and income estimates is reflected in the accounting period in
which the facts that require the revision become known. Income is recognized by
applying the percentage completed to the projected total income for each
contract in progress. Cost of revenues consist of direct material, labor and
subcontracting costs and indirect costs related to contract performance, such as
indirect labor, supplies and tools. Cost of revenues also include the
manufacturing costs related to the amphibious undercarriages sold and costs
associated with the services provided for site assessments and remediation
activities. Selling, general and administrative expenses have historically
consisted primarily of compensation and benefits to owners as well as to sales
and administrative employees, fees for professional services and other general
office expenses. Selling, general and administrative expenses have also
historically included incentive and discretionary bonuses paid to owners,
including amounts paid in lieu of S corporation distributions to enable them to
meet their income tax obligations.

     This Annual Report on Form 10-K and Management's Discussion and Analysis of
Results of Operations and Financial Condition include certain forward-looking
statements, which are identified by the use of the words "believes", "expects"
and similar expressions that contemplate future events. Numerous important
factors, risks and uncertainties affect the Company's operating results and
could cause the Company's actual results to differ materially from the results
implied by these or any other forward-looking statements made by, or on behalf
of the Company. There can be no assurance that future results will meet
expectations. These important factors, risks and uncertainties include, but are
not limited to, those described in the following paragraphs and in the
discussion above in this Annual Report under the heading "Business".

     The marine construction industry along the U. S. Gulf Coast is highly
seasonal as a result of weather conditions, the availability of daylight hours
and the timing of capital expenditures by oil and gas companies. Historically,
the Founding Companies have performed a substantial portion of their services
during the period from March through November, and, therefore, a
disproportionate portion of their contract revenues, gross profit and net income
generally has been earned during the second and third quarters of the calendar
year. Because of this seasonality, the Company's future full year results are
not likely to be a direct multiple of any particular quarter or combination of
quarters.

     Additionally, the Company's results of operations will also be affected by
the level of oil and gas exploration and development activity maintained by oil
and gas companies in the Gulf of Mexico. The level of exploration and
development activity is related to several factors, including trends of oil and
gas prices, exploration and production companies' expectations of future oil and
gas prices, and changes in technology which reduce costs and improve expected
returns on investment.

     Certain risks are definitely inherent under contracts which are priced on a
fixed-price basis. The revenues, costs and gross profit realized on a contract
will often vary from the estimated amounts for various reasons, including errors
in estimates or bidding, changes in the availability and cost of labor and
material and

                                       12
<PAGE>   15

variations in productivity from the original estimates. These variations and the
risks inherent in the marine construction industry may result in revenues and
gross profits different from those originally estimated and can result in
reduced profitability or losses on projects.

     In accordance with the applicable accounting rules of the Commission,
Woodson Construction Company (collectively with three affiliated companies,
"Woodson") has been identified as the "accounting acquiror" for financial
statement presentation purposes. Consequently, the Company's historical
financial statements for periods ended on or before October 31, 1997, the
effective date of the acquisitions of the Founding Companies for accounting
purposes, are the consolidated historical financial statements of Woodson. As
used in this discussion, the "Company" means (i) Woodson prior to October 31,
1997 and (ii) TCMS and its consolidated subsidiaries on that date and
thereafter.

consolidated financial statements.

  Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

     Revenues. Revenues increased $39.6 million, or 220.7%, from $17.9 million
for the year ended December 31, 1996 to $57.5 million for the year ended
December 31, 1997. Approximately $14.0 million of the increase in revenues was
attributable to the acquisitions of the Founding Companies on November 4, 1997.
The remaining increase was primarily attributable to higher pipeline
construction revenues resulting from improved market activity in 1997.

     Cost of revenues. Cost of revenues increased $32.9 million, or 242.9%, from
$13.6 million for the year ended December 31, 1996 to $46.5 million for the year
ended December 31, 1997. The increase in cost of revenues was consistent with
the revenue increase. As a percentage of revenues, cost of revenues increased to
80.9% during 1997 from 75.6% for 1996. The increase was due primarily to lower
margins achieved during 1997 on projects that were considerably larger in size
and scope than in 1996.

     Selling, general and administrative expenses. Selling, general and
administrative expenses increased $3.3 million, or 112.6%, for the year ended
December 31, 1997 compared to the 1996 period. The single largest component of
the increase was a $2.2 million non-cash compensation charge reflected during
the fourth quarter of 1997 related to the issuance of shares of Common Stock to
management of the Company. As a percentage of revenues, selling, general and
administrative expenses (exclusive of the non-cash compensation charge) were
7.1% during 1997, compared to 16.6% during 1996. The percentage decrease was
primarily due to the significant increase in revenues without a commensurate
increase in overhead expenses.

                                       13
<PAGE>   16

     Depreciation and amortization. Depreciation and amortization expenses
increased $1.5 million, or 274.0%, from $0.6 million for the year ended December
31, 1996 to $2.1 million for the year ended December 31, 1997. The increase was
due to: (1) additional property, plant and equipment placed in service during
late 1996 and early 1997, and (2) the acquisition of equipment owned by the
Founding Companies effective November 4, 1997 under the purchase method of
accounting.

     Interest income (expense), net. Interest expense, net of interest income
totaled $0.5 million during the year ended December 31, 1997, as compared to net
interest income of $0.05 million during 1996. The significant increase was due
to: (1) higher average debt levels resulting from drawdowns on the corporate
revolver after the completion of the Offering, and (2) amortization of debt
issuance costs related to the credit agreement, Lender Warrant, and MGCO
Warrant. See "Liquidity and Capital Resources -- The Company" below for
discussion of credit agreement and related financings.

     Other income, net. During 1996 and 1997, other income, net consisted
primarily of gains recognized on the sale of available-for-sale securities.

  Year Ended December 31, 1996 Compared to Year Ended December 31, 1995

     Revenues. Revenues totaling $17.9 million for the year ended December 31,
1996 were virtually unchanged from the 1995 results as a $0.7 million decline in
environmental services revenues resulting from less work with the Louisiana
Department of Environmental Quality was offset by a $0.6 million increase in
revenues from sales of amphibious undercarriages.

     Cost of revenues. Cost of revenues increased $0.8 million, or 6.6%, in 1996
compared to 1995. The increase was primarily due to additional maintenance costs
during equipment downtime. As a percentage of revenue, cost of revenues was
75.6% in 1996 compared to 70.4% in 1995.

     Selling, general and administrative expenses. Selling, general and
administrative expenses totaling $3.0 million reflected an increase of $0.3
million, or 11.1%, in 1996 compared to 1995. The increase was primarily due to a
one-time bonus paid to officers and the employment of a safety consultant. As a
percentage of revenues, selling, general and administrative expenses were 16.6%
in 1996 compared to 14.8% in 1995.

     Depreciation and amortization. Depreciation and amortization expenses were
essentially unchanged for 1996 compared to 1995.

LIQUIDITY AND CAPITAL RESOURCES -- THE COMPANY

     On November 4, 1997, TCMS completed the Offering, which involved the
issuance of 5,750,000 shares of Common Stock at a price of $18.00 per share
(before deducting underwriting discounts and commissions), including 750,000
shares pursuant to an over-allotment option granted by the Company to the
underwriters in connection with the Offering. The net proceeds to TCMS after
deducting underwriter discounts and commissions totaled $94.7 million, of which
$85.7 million was used to pay the cash portion of the purchase prices relating
to the Acquisitions with the remainder being used to pay certain indebtedness of
the Founding Companies.

     The Company generated $5.8 million in net cash from operating activities
during the year ended December 31, 1997. Net cash used in investing activities
totaled approximately $96.2 million, principally for the cash purchase price of
the Acquisitions as noted above. Reflecting the net proceeds from the Offering,
net cash provided by financing activities totaled $91.7 million. At December 31,
1997, the Company had working capital of $3.4 million, including $2.5 million in
current maturities of long-term debt.

     The Company generated $2.7 million in net cash from operating activities in
the year ended December 31, 1996. Net cash used in investing activities was
approximately $1.8 million, principally for capital expenditures. Net cash used
in financing activities was $0.6 million, primarily for the payment of
dividends. At December 31, 1996, the Company had working capital of $3.8
million, including $0.7 million in short-term borrowings.

                                       14
<PAGE>   17

     On October 28, 1997, TCMS entered into a credit agreement (the "Credit
Agreement") with Joint Energy Development Investments, Limited Partnership, an
affiliate of Enron Capital & Trade Resources Corp. (the "Lender"). The Credit
Agreement extends through October 1999 and provides for borrowings up to $75.0
million, with the initial borrowing availability being $50.0 million (the
"Initial Availability") and the remaining $25.0 million being made available
from time to time and in such amounts as the Lender shall determine in its sole
discretion. The Credit Agreement is divided into two tranches: (a) a senior
secured revolving credit facility (the "Revolving Credit Facility"), providing
for borrowings of up to $60.0 million ($40.0 million of which comprises part of
the Initial Availability) and (b) $15.0 million of senior subordinated term loan
borrowings (the "Term Loan Facility"), of which $10.0 million comprises the
remainder of the Initial Availability. During 1997, borrowings were only made
under the Revolving Credit Facility and the outstanding balance totaled $10.0
million at December 31, 1997.

     At December 31, 1997, the Company had commitments of $0.7 million for the
purchase or construction of capital assets. The Company plans to fund these
capital expenditures through cash flow from operations and, if necessary,
additional borrowings under the Credit Agreement.

     The Company intends to continue pursuing attractive corporate and asset
acquisition opportunities. The timing, size or success of any acquisition effort
and the associated potential capital commitments are unpredictable. The Company
expects to fund future acquisitions through the issuance of additional equity as
well as through a combination of working capital, cash flow from operations and
borrowings, including borrowings under the Credit Agreement.

     The Company is, from time to time, exposed to various contingencies arising
in the ordinary course of business, including, among others, legal actions
arising from accidents and other events resulting from the operational risks
inherent in the marine construction business. For a discussion of two class
action lawsuits involving large claims for compensatory and punitive damages
against one of the Founding Companies arising from events that occurred during
the course of a pipeline installation project for a third party gas transmission
company (and as to which the total amount of damages to which the Company may
have exposure cannot reasonably be estimated at this time), see
"Business -- Legal Proceedings." There can be no assurance that these lawsuits
or other legal actions or contingencies that may arise in the future will not
have a material adverse effect on the Company's business, financial condition,
results of operations and liquidity.

YEAR 2000

     The Company is now assessing the potential impact of the situation commonly
referred to as the "Year 2000 Problem." The Year 2000 Problem, which is common
to most organizations, concerns the inability of information systems, primarily
computer software programs, to properly recognize and process date sensitive
information related to the year 2000 and beyond. The Company is currently
evaluating the expected cost to be incurred in connection with the Year 2000
Problem.

INFLATION

     Inflation has not had a material impact on the Company's results of
operations for the last three years.

(1) The financial information is presented for the twelve months ended May 31.

(2) Reflects results of operations for the twelve months ended December 31,
    1996.

  CSI's results for the six months ended June 30, 1997 compared to the six
months ended June 30, 1996

     Revenue. Revenue increased $5.8 million, or 152%, for the six months ended
June 30, 1997 compared to the corresponding period in the prior year. The
increase was primarily due to the additional revenue generated by the M/V
Discovery, which was acquired in early January 1997.

     Cost of revenue. Cost of revenue increased $3.2 million, or 129%, for the
six months ended June 30, 1997 compared to the corresponding period in the prior
year. The increase was primarily due to costs associated with the operation of
the M/V Discovery. As a percentage of revenue, cost of revenue was 58.8% for the
six months ended June 30, 1997 compared to 64.6% for the corresponding period in
the prior year. The decrease as a percentage of revenue was due to increased
marine construction activity.

     Selling, general and administrative expenses. Selling, general and
administrative expenses increased $0.1 million, or 9.5%, for the six months
ended June 30, 1997 compared to the corresponding period in the prior year. As a
percentage of revenue, selling, general and administrative expenses were 13.2%
for the six months ended June 30, 1997 compared to 30.4% for the corresponding
period in the prior year. The percentage decrease was primarily attributable to
the significant increase in revenue relating to the M/V Discovery without a
commensurate increase in overhead expenses.

     Depreciation and amortization. Depreciation and amortization expenses
increased $43,000, or 21.3%, for the six months ended June 30, 1997 compared to
the corresponding period in the prior year. The increase was related to the
acquisition of, and improvements to, the M/V Discovery.

  CSI's results for the year ended December 31, 1996 compared to the year ended
May 31, 1995

     Revenue. Revenue increased $3.2 million, or 61.3%, in 1996 compared to the
1995 period. The increase was primarily due to an increase in marine
construction activity in the Gulf of Mexico.

     Cost of revenue. Cost of revenue increased $1.9 million, or 57.9%, in 1996
compared to the 1995 period. The increase in cost of revenue was primarily due
to the corresponding increase in revenue and related direct costs resulting from
the increased activity. As a percentage of revenue, cost of revenue was 62.3% in
1996 compared to 63.8% in the 1995 period.

     Selling, general and administrative expenses. Selling, general and
administrative expenses increased $0.2 million, or 6.6%, in 1996 compared to the
1995 period. As a percentage of revenue, selling, general and administrative
expenses were 28.8% in 1996 compared to 43.7% in the 1995 period. The percentage
decrease was primarily due to the significant increase in revenue experienced in
1996 without a commensurate increase in overhead expenses.

                                       16
<PAGE>   19

     Depreciation and amortization. Depreciation and amortization expenses
increased $0.1 million, or 33.5%, for 1996 compared to the 1995 period. The
increase was related to additions of property, plant and equipment in 1995 and
1996.

  CSI's results for the year ended May 31, 1995 compared to the year ended May
31, 1994

     Revenue. Revenue decreased nominally in 1995 compared to the 1994 period.

     Cost of revenue. Cost of revenue increased $0.4 million, or 12.5%, in 1995
compared to the 1994 period. As a percentage of revenue, cost of revenue was
63.8% in 1995 compared to 55.6% in the 1994 period. The percentage increase was
primarily due to lower margins on contracts for hydrostatic testing services
performed in the 1995 period, resulting from price discounting.

     Selling, general and administrative expenses. Selling, general and
administrative expenses increased $0.6 million, or 32.5%, in 1995 compared to
the 1994 period. The increase was primarily due to an expansion of the
administrative staff and the payment of a one-time bonus of $100,000 to CSI's
principal officers. As a percentage of revenue, selling, general and

     Revenue. Revenue for the seven months ended December 31, 1995 included
three significant high-margin jobs totaling $2.5 million, or 41.4% of the total
revenue for the period. These unusually high-margin, short-duration jobs were
bid on the basis of standard rental rates and included substantially higher
built-in margins compared to competitive bid projects.

     Cost of revenue. As a percentage of revenue, cost of revenue was 49.8%,
compared to 63.8% for the twelve months ended May 31, 1995. The decrease as a
percentage of revenue was due primarily to the higher-margin jobs included in
the job mix in the seven-month period.

     Selling, general and administrative expenses. As a percentage of revenue,
selling, general and administrative expenses were 21.2%, compared to 43.7% for
the twelve months ended May 31, 1995. The seven months represented an active
period during which revenues increased substantially while selling, general and
administrative expenses remained relatively constant.

     Depreciation and Amortization. On a per-month basis, depreciation and
amortization expenses were relatively constant in the seven months ended
December 31, 1995 and the twelve months ended May 31, 1995.

</TABLE>

  HBH's results for the six months ended June 30, 1997 compared to the six
months ended June 30, 1996

     Revenue. Revenue increased $4.8 million, or 25.1%, for the six months ended
June 30, 1997 compared to the corresponding period in the prior year. The
revenue increase was attributable to improved pipeline construction activity in
1997, with two major projects contributing $16.8 million in revenue.

     Cost of revenue. Cost of revenue increased $3.1 million, or 18.7%, for the
six months ended June 30, 1997 compared to the corresponding period in the prior
year. The increase was primarily attributable to costs related to the higher
level of activity in pipeline construction in 1997. Improved pricing and less
subcontracting costs as a percentage of overall cost on the major projects in
the current period have contributed to higher margins. As a percentage of
revenue, cost of revenue was 81.3% for the six months ended June 30, 1997
compared to 85.7% for the corresponding period in the prior year.

     Selling, general and administrative expenses. Selling, general and
administrative expenses increased $0.2 million, or 38.6%, for the six months
ended June 30, 1997 compared to the corresponding period in the prior year. The
increase was primarily attributable to accruals of performance bonuses in 1997,
which were partially offset by the elimination of consulting fees paid in 1996
to HBH's former sole shareholder. As a percentage of revenue, selling, general
and administrative expenses were 2.8% for the six months ended June 30, 1997
compared to 2.5% for the corresponding period in the prior year.

     Depreciation and amortization. Depreciation and amortization expenses
increased $31,000, or 4.3%, for the six months ended June 30, 1997 compared to
the corresponding period in the prior year due to additions to its property,
plant and equipment.

  HBH's results for 1996 compared to 1995

     Revenue. Revenue increased $22.1 million, or 150%, in 1996 compared to
1995. The increase was due primarily to full year operating results of the
BH-400, which was placed in service in October 1995, and the completion of a
large pipeline installation project which generated $13.0 million in revenue.

     Cost of revenue. Cost of revenue increased $16.9 million, or 101%, in 1996
compared to 1995. The increase was primarily attributable to direct costs, such
as labor, associated with the operations of the BH-400. As a percentage of
revenue, cost of revenue was 91.5% in 1996 compared to 113.7% in 1995.

     Selling, general and administrative expenses. Selling, general and
administrative expenses increased $0.1 million, or 15.3%, in 1996 compared to
1995. The increase was primarily attributable to increased salaries. As a
percentage of revenue, selling, general and administrative expenses were 2.7% in
1996 compared to 5.9% in 1995.

     Depreciation and amortization. Depreciation and amortization expenses
increased $0.6 million, or 70.2%, in 1996 compared to 1995, due primarily to the
acquisition of the BH-400 in October 1995.

  HBH's results for 1995 compared to 1994

     Revenue. Revenue decreased $0.5 million, or 3.2%, in 1995 compared to 1994.
The decrease was due primarily to the completion of a large pipeline
installation project in 1994, which generated $5.6 million in revenue.

     Cost of revenue. Cost of revenue increased $4.2 million, or 33.5%, in 1995
compared to 1994. The increase was primarily attributable to the late delivery
of the BH-400, which delayed the start of two fixed-price contract jobs, thereby
increasing costs relating to standby time, weather downtime and sub-contract
services. As a percentage of revenue, cost of revenue was 114% in 1995 compared
to 82.5% in 1994.

     Selling, general and administrative expenses. Selling, general and
administrative expenses decreased $0.1 million, or 6.7%, in 1995 compared to
1994. The decrease was primarily attributable to the payment of performance
bonuses in 1994. As a percentage of revenue, selling, general and administrative
expenses were 5.9% in 1995 compared to 6.1% in 1994.

     Depreciation and amortization. Depreciation and amortization expenses
increased $0.4 million, or 73.2%, in 1995 compared to 1994, due primarily to the
acquisition of the BH-400 in October 1995 and other additions to property, plant
and equipment in 1994 and 1995.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the stockholders of TransCoastal Marine Services, Inc. and subsidiaries:

     We have audited the accompanying consolidated balance sheets of
TransCoastal Marine Services, Inc. (a Delaware corporation) and subsidiaries as
of December 31, 1996 and 1997, and the related consolidated statements of
operations, stockholders' equity and cash flows for each of the three years then
ended. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

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

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
TransCoastal Marine Services, Inc. and subsidiaries as of December 31, 1996 and
1997, and the consolidated results of their operations and their cash flows for
each of the three years in the period then ended, in conformity with generally
accepted accounting principles.

     As discussed in Note 1, the accompanying consolidated financial statements
reflect the Company on a historical basis with the Woodson Companies ("Woodson")
as the accounting acquiror.

              TRANSCOASTAL MARINE SERVICES, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION

     TransCoastal Marine Services, Inc. ("TCMS") was organized in April 1996 to
create a fully integrated marine construction company focusing on transition
zone and shallow water regions of the U.S. Gulf Coast. On November 4, 1997, TCMS
acquired, simultaneously with the closing of its initial public offering (the
"Offering"), four privately owned marine construction businesses (the "Founding
Companies") and certain real properties used in the businesses of the Founding
Companies in exchange for consideration consisting of cash, common stock of TCMS
(the "Common Stock") and debt assumption. Unless otherwise indicated, all
references herein to the "Company" include the Founding Companies, and
references to "TCMS" mean TransCoastal Marine Services, Inc., prior to the
consummation of the acquisitions of the Founding Companies.

     The Woodson Companies ("Woodson"), one of the Founding Companies, has been
identified as the "accounting acquiror" for financial statement presentation
purposes. The acquisitions of the remaining Founding Companies were accounted
for using the purchase method of accounting, with the results of operations
included from October 31, 1997, the effective closing date of the acquisitions
for accounting purposes. The allocation of purchase price to the assets acquired
and liabilities assumed has been initially assigned and recorded based on
preliminary estimates of fair value and may be revised as additional information
concerning the valuation of such assets and liabilities becomes available.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Principles of Consolidation

     The accompanying consolidated financial statements include the accounts of
TCMS and its wholly owned subsidiaries. All significant intercompany accounts
and transactions have been eliminated in consolidation.

  Use of Estimates

     The Company's financial statements are prepared in accordance with
generally accepted accounting principles ("GAAP"). Financial statements prepared
in accordance with GAAP require the use of management 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.
Additionally, management estimates affect the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

  Cash and Cash Equivalents

     The Company considers all highly liquid investments with an original
maturity of three months or less as cash equivalents excluding certain
restricted amounts. Restricted cash represents cash equivalent investments to
support letters of credit established by the Company in the normal course of
business with certain vendors.

  Property, Plant and Equipment

     Property, plant and equipment are recorded at cost less accumulated
depreciation. Depreciation is computed using the straight-line method over the
estimated useful lives of the assets ranging from 3 years to 31.5 years.
Leasehold improvements are capitalized and amortized over the lesser of the
lives of the leases or the estimated useful lives of the assets.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated.

              TRANSCOASTAL MARINE SERVICES, INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  Goodwill

     Goodwill represents the excess of the aggregate purchase price paid by the
Company over the fair market value of the net tangible assets acquired. Goodwill
is being amortized on a straight-line basis over 40 years, which represents
management's estimation of the related benefit to be derived from the acquired
businesses. Under Accounting Principles Board ("ABP") Opinion No. 17 and SFAS
No. 121, the Company periodically evaluates whether events and circumstances
after the acquisition date indicate that the remaining balance of goodwill may
not be recoverable. If factors indicate that goodwill should be evaluated for
possible impairment, the Company would compare estimated undiscounted future
cash flow from the related operations to the carrying amount of goodwill. If the
carrying amount of goodwill were greater than undiscounted future cash flow, an
impairment loss would be recognized. Any impairment loss would be computed as
the excess of the carrying amount of goodwill over the estimated fair value of
the goodwill (calculated based on discounting estimated future cash flows).
Accumulated amortization of goodwill was $275,000 as of December 31, 1997.

  Dry-dock Costs

     Dry-dock costs are third-party costs associated with scheduled maintenance
on the Company's marine construction vessels. Costs incurred in connection with
dry dockings are capitalized and amortized over the period to the next scheduled
dry docking.

  Mobilization Costs

     Mobilization costs incurred on moving marine vessels and associated
equipment to their contractual locations to commence operations are capitalized
and amortized over the contract term.

  Debt Issuance Costs

     Debt issuance costs are included in other noncurrent assets and are
amortized to interest expense over the scheduled maturity of the debt. As of
December 31, 1997, debt issuance costs and accumulated amortization totaled $3.3
million and $0.2 million, respectively.

  Revenue Recognition

     Revenues from construction contracts, which are typically of short
duration, are recognized on the percentage-of-completion method. Under this
method, the percentage of completion is determined by comparing contract costs
incurred to date with total estimated contract costs. Income is recognized by
applying the percentage complete to the projected total income for each contract
in progress. Contract costs include all direct material, labor and subcontract
costs and those indirect costs related to contract performance, such as indirect
labor, supplies and tools. Revisions in cost and income estimates are reflected
in the accounting period in which the facts requiring revision become known. In
addition, anticipated losses to be incurred on contracts in progress are charged
to income in the period such losses are determined. With regard to pipeline
testing services performed, the Company recognizes revenues on an as-billed
basis, with an accrual made at each period end for unbilled revenue.

  Fair Value of Financial Instruments

     The Company considers the fair value of all financial instruments to not be
materially different from their carrying values at each year-end based on
management's estimate of the Company's ability to borrow funds under terms and
conditions similar to those applicable to the Company's existing debt.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  Income Taxes

     The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes."
Under SFAS No. 109, the Company recognizes deferred tax liabilities and assets
for the expected future tax consequences of events that have been recognized
differently in the financial statements or tax returns. Under this method,
deferred tax liabilities and assets are determined based on the difference
between the financial statement carrying amounts and tax basis of assets and
liabilities using enacted tax rates and laws in effect in the years in which the
differences are expected to reverse. Deferred tax assets are evaluated for
realization based on a more-likely-than-not criteria in determining if a
valuation allowance should be provided. Income tax expense is the tax payable
for the year and the change during the year in deferred tax assets and
liabilities.

     Two of the three companies comprising the Woodson Companies elected to be
taxed as S Corporations for federal and state income tax purposes whereby
shareholders are liable for individual federal and state income taxes on their
allocated portions of the applicable entity's taxable income. Upon the closing
of the Offering, the S Corporation status was changed to that of a C
Corporation. Accordingly, the historical financial statements as they relate to
the period prior to the Offering do not include provisions for income taxes
relating to those entities.

     Pro forma net income consists of the historical net income of the Company,
including two S Corporations, adjusted for income taxes that would have been
recorded had each company operated as a C Corporation.

  Concentrations of Credit and Business Risk

     The Company's customers are primarily major and independent oil and gas
exploration and production companies, drilling contractors, hydrocarbon
transportation companies and other marine construction companies, which
potentially expose the Company to concentrations of credit risk. The Company
performs ongoing credit evaluation of its customers and requires posting of
collateral when deemed appropriate. The Company provides allowances for possible
credit losses when necessary. Additionally, the Company's results of operations
will also be affected by the level of oil and gas exploration and development
activity maintained by oil and gas companies in the Gulf of Mexico. The level of
exploration and development activity is related to several factors, including
trends of oil and gas prices, exploration and production companies' expectations
of future oil and gas prices, and changes in technology which reduce costs and
improve expected returns on investment. Although the Company is directly
affected by the financial stability of the oilfield services industry,
management does not believe significant credit risk exists at December 31, 1997.

  Earnings Per Share

     SFAS No. 128 "Earnings Per Share" was issued in February 1997.
Implementation of SFAS No. 128 is required for periods ending after December 15,
1997. SFAS No. 128 requires dual presentation of earnings per share (EPS); basic
EPS and diluted EPS. Basic EPS excludes dilution and is computed by dividing net
income by the weighted average number of common shares outstanding for the
period. Diluted EPS reflects the potential dilution that could occur if
securities or other contracts to issue common stock were exercised or converted
into common stock.

     The calculation of diluted earnings per share is similar to basic earnings
per share except that the denominator includes dilutive common stock equivalents
such as stock options and warrants. Weighted average shares outstanding for
calculation of diluted earnings per share totaled 1,031,000, 1,722,000, and
3,393,000 for 1995, 1996, and 1997, respectively. Weighted average diluted
shares outstanding at December 31, 1997 included 30,000 shares related to a
warrant issued to a financial advisory firm that provided services in
conjunction with the Acquisitions (see Note 9).

  Available-for-Sale Securities

     In accordance with SFAS No. 115, "Accounting for Certain Investments in
Debt and Equity Securities," the Company's marketable equity securities are
included in an available-for-sale caption in the accompanying consolidated
balance sheets and are carried at market value, with the difference between cost
and market value, net of related tax effects, included as a component of
stockholders' equity.

  Recent Accounting Pronouncements

     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income", which is effective for the Company's year ending December 31, 1998.
SFAS No. 130 establishes standards for the reporting and displaying of
comprehensive income and its components. The Company will be analyzing SFAS No.
130 during 1998 to determine what, if any, additional disclosures will be
required.

     In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information", which is effective for the Company's
year ended December 31, 1998. This statement establishes standards for the
reporting of information about operating segments. The Company will be analyzing
SFAS No. 131 during 1998 to determine what, if any, additional disclosures will
be required.

3. BUSINESS COMBINATIONS

     On November 4, 1997, TCMS acquired in separate transactions (collectively,
the "Acquisitions"), simultaneously with the closing of the Offering, the
Founding Companies and certain real properties used in the businesses of the
Founding Companies. The Acquisitions have been accounted for under the purchase
method of accounting. The aggregate consideration paid for the Acquisitions was
$85.7 million in cash, issuance of $3.0 million in 8% notes payable over a
ten-year term ending in 2007, and 2,142,441 shares of Common Stock. Funding of
the cash portion of the consideration was provided by funds raised through the
Offering. The accompanying consolidated balance sheet at December 31, 1997
includes allocations of the respective purchase prices and is subject to final
adjustment. One of the Acquisitions is subject to a post-closing adjustment,
based on a multiple of estimated earnings before interest, taxes, depreciation
and amortization ("EBITDA") and payable in shares of Common Stock. Based on a
preliminary determination,

                                       31
<PAGE>   34
              TRANSCOASTAL MARINE SERVICES, INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

the Company currently estimates that such post-closing adjustment will not
exceed $0.5 million. The allocations resulted in goodwill recognized of $71.1
million representing the excess of purchase price over fair value of the net
assets acquired. The goodwill allocation includes $14.0 million of excess
purchase price attributable to the 975,000 shares of Common Stock issued to the
founders of TCMS during 1996 which were revalued to a fair market value of
$14.40 per share.

     Set forth below are unaudited pro forma combined revenues and income data
reflecting the pro forma effect of the Acquisitions on the Company's results
from operations for the years ended December 31, 1996 and 1997. The unaudited
pro forma data presented below consists of the income statement data from
operations as presented in these consolidated financial statements plus the
Founding Companies for the year ended December 31, 1996 and the ten months ended
October 31, 1997 (in thousands, except per share amounts). These pro forma
results are not necessarily indicative of the results which would actually have
occurred if the Acquisitions had taken place at the beginning of the periods
presented, nor are they necessarily indicative of future results.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  Credit Agreement

     On October 28, 1997, TCMS entered into a credit agreement ("Credit
Agreement") with Joint Energy Development Investments, Limited Partnership, an
affiliate of Enron Capital & Trade Resources Corp. (the "Lender"). The Credit
Agreement provides for borrowings up to $75.0 million, with the initial
borrowing availability being $50.0 million (the "Initial Availability") and the
remaining $25.0 million being made available from time to time and in such
amounts as the Lender shall determine at its sole discretion. The Credit
Agreement is divided into two tranches: (a) a senior secured revolving credit
facility (the "Revolving Credit Facility"), providing for borrowings of up to
$60.0 million ($40.0 million of which comprises part of the Initial
Availability) and (b) $15.0 million of senior subordinated term loan borrowings
(the "Term Loan Facility"), of which $10.0 million comprises the remainder of
the Initial Availability.

     Borrowings under the Revolving Credit Facility bear interest, at the option
of the Company, at either the Base Rate plus 25 basis points (8.75% at December
31, 1997) or at LIBOR plus 275 basis points. The Base Rate is defined as the
higher of the federal funds rate plus 50 basis points or the prime rate.
Borrowings under the Term Loan Facility bear interest, at the option of the
Company, at either the Base Rate plus 75 basis points or at LIBOR plus 375 basis
points. Interest under both facilities is payable quarterly. During 1997,
borrowings were made only under the Revolving Credit Facility and were based
upon the Base Rate option. Commitment fees on the daily average unused
commitment under the Revolving Credit Facility and the Term Loan Facility is
payable quarterly at a rate per annum of .375% and .5%, respectively. Borrowings
under the Credit Agreement are secured by liens on substantially all of the
Company's assets (including accounts receivable and after-acquired property) and
a pledge of the capital stock of the Founding Companies and each of the
Company's remaining subsidiaries.

     The Credit Agreement requires the Company to comply with various loan
covenants, including (a) maintenance of certain financial ratios, (b)
restrictions on additional indebtedness and (c) restrictions on liens,
guarantees, advances and dividends. The Company did not borrow under the Term
Loan Facility during 1997; the balance outstanding under the Revolving Credit
Facility totaled $10.0 million at December 31, 1997.

     The Credit Agreement extends through October 1999 and all outstanding
principal and accrued and unpaid interest under the Revolving Credit Facility
and the Term Loan Facility is due and payable on that date. The Credit Agreement
contains mandatory prepayment provisions requiring prepayment of outstanding
borrowings from the issuance of debt or equity securities for cash and any
proceeds from other borrowings. In connection with the Credit Agreement, the
Company issued to the Lender a warrant to acquire 175,000 shares of Common Stock
at an exercise price equal to the initial per share price to the public in the
Offering of $18.00. The consideration for that warrant was $1,750 and the
warrant is exercisable for five years from its date of issuance. Upon issuance,
the warrant was valued at $1.1 million based on fair market value as determined
by management.

6. STOCKHOLDERS' EQUITY

  Preferred Stock

     The Company's Board of Directors is authorized to issue preferred stock of
the Company, of which none was outstanding at December 31, 1996 and 1997.

  Common Stock

     On November 4, 1997, TCMS completed the Offering, which involved the
issuance of 5,750,000 shares of Common Stock at a price of $18.00 per share
(before deducting underwriting discounts and commissions), including 750,000
shares pursuant to an over-allotment option granted by the Company to the
underwriters in connection with the Offering. The net proceeds to TCMS after
deducting underwriter discounts and commissions totaled $94.7 million.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     In August 1997, TCMS effected a 1,000-for-one stock split of the
outstanding shares of Common Stock. In addition, TCMS increased the number of
authorized shares of Common Stock to 20,000,000 and authorized 3,000,000 shares
of restricted common stock ("Restricted Common Stock"). The effect of the stock
split has been retroactively reflected in the accompanying financial statements
and related notes thereto.

     In March and April 1997, 175,000 shares and 100,000 shares of Common Stock,
respectively, were sold to management at $.001 per share. TCMS recorded a
non-recurring, non-cash compensation charge of $2.2 million effective with the
closing of the Offering, representing the difference between the amount paid for
the shares and the estimated fair value of the shares on the date of sale of
such Common Stock.

     In April 1997, TCMS issued 3,000 shares of Common Stock to a consultant for
services performed in connection with the Offering. The $12,200 difference
between the amount paid and the estimated fair market value of the shares on the
date of issue was recorded as deferred offering costs in the second quarter of
1997. In July 1997, an additional 3,000 shares of Common Stock were issued with
the same terms to another consultant for services performed in connection with
the Offering. An additional $32,000 was recorded as deferred offering costs in
the third quarter of 1997. Such costs were charged to additional paid in capital
upon consummation of the Offering.

  Restricted Common Stock

     Shares of Restricted Common Stock have no voting rights. Shares of
Restricted Common Stock are convertible into shares of Common Stock on a
share-for-share basis (a) in the event of certain ownership changes, (b) 18
months after the Offering or (c) in the event of approval by a majority of
holders of the Common Stock.

     Effective November 4, 1997, the Company executed and delivered an agreement
whereby certain shareholders exchanged an aggregate of 250,000 shares of their
registered Common Stock for Restricted Common Stock effective with the closing
of the Offering. No shares of Restricted Common Stock were outstanding at
December 31, 1996.

  Stock Options

     In August 1997, the Board of Directors and the stockholders of TCMS
approved the 1997 Stock Option Plan (the "Plan"). The Plan provides for the
granting of stock options to directors, executive officers, certain other
employees and certain non-employee consultants of the Company. The Plan, which
permits up to 750,000 shares of Common Stock to be issued, terminates on August
2007. In general, the terms of the option awards (including vesting schedules)
will be established by the Compensation Committee of the Company's Board of
Directors.

     The following table summarizes activity under the Plan for the year ended
December 31, 1997:

     At December 31, 1997, no option shares were exercisable. Unexercised
options expire during 2007.

     SFAS No. 123, "Accounting for Stock-Based Compensation," allows entities to
choose between a fair value-based method of accounting for employee stock
options or similar equity instruments and the current intrinsic, value-based
method of accounting prescribed by Accounting Principles Board ("APB") Opinion
No. 25. Entities electing to remain with the accounting in APB Opinion No. 25
must make pro forma disclosures of net income and earnings per share as if the
fair value method of accounting had been applied. TCMS has elected to account
for the issuance of stock options pursuant to APB Opinion No. 25. Therefore,
there is no effect on the Company's financial position and results of operations
as a result of this pronouncement.

     The following pro forma summary of the Company's consolidated results of
operations have been prepared as if the fair value based method of accounting
for stock based compensation as required by SFAS No. 123 had been applied (in
thousands, except per share amounts):

  Common Stock Warrants

     During the first quarter of 1997, TCMS entered into an advisory agreement
with an investment banking firm, which was amended in June 1997 to provide for
the sale of a warrant to acquire 50,000 shares of Common Stock (see Note 9).
Additionally, in connection with the Credit Agreement, the Company issued to its
primary lender a warrant to acquire 175,000 shares of Common Stock at an
exercise price equal to the initial per share price to the public in the
Offering of $18.00. As of December 31, 1997, no warrants had been exercised.
These warrants were valued at approximately $1.2 million and are being amortized
over the two-year term of the Credit Agreement.

9. COMMITMENTS AND CONTINGENCIES

  Litigation

     The Company is currently involved in two class action lawsuits for
unspecified personal injury and property damages arising from events in October
1991 and January 1992 during the course of a pipeline installation project for a
third party gas transmission company. One of the class actions, involving
approximately 9,840 class members, entitled Rivera v. United Gas Pipeline Co.,
No. 28738, was instituted against Woodson Construction Company, Inc. on October
29, 1991 in the 40th Judicial District Court, Parish of St. John the Baptist,
State of Louisiana, and the other class action, involving approximately 7,858
class members, entitled Husseiney v. United Gas Pipeline Co., No. 29089, was
instituted on January 27, 1992 against Woodson Construction Company, Inc. in the
40th Judicial District Court, Parish of St. John the Baptist, State of
Louisiana. The claims of 24 representative class members in each case were tried
in 1995, and judgments were rendered against Woodson Construction Company, Inc.,
which were later affirmed by the court of appeal. In the Rivera lawsuit, five of
the 24 representative plaintiffs were awarded compensatory damages of $7,500 in
the aggregate, but punitive damages were denied. In the Husseiney lawsuit,
compensatory damages of $18,589 and punitive damages of $9,500 in the aggregate
were assessed against Woodson Construction Company, Inc. in favor of 16 of the
24 representative plaintiffs. In both lawsuits, the compensatory damages awarded
are expected to be covered by the Company's insurance, but punitive damage
awards are not expected to be covered by insurance. The compensatory and
punitive damages awarded to the 16 representative class members varied according
to the representatives' proximity to the incident and individual experience with
respect to it. The amount of compensatory and punitive damages applicable to the
remaining 7,834 class members who seek to adjudicate their damage claims will be
litigated on an individual basis. Until those remaining damage claims are
finally adjudicated, settled, dismissed or otherwise terminated, the total
amount of the punitive damages to which the Company may be subject cannot
reasonably be estimated, and there can be no assurance that it will not be
materially adverse to the Company's financial position or results of operations.
In July 1997, all parties involved applied to the Louisiana Supreme Court for
further discretionary review of the existing judgments. In December 1997, the
Louisiana Supreme Court declined to review the judgments in both cases.

     The Company is involved in various other lawsuits arising in the ordinary
course of business, some of which involve substantial claims for damages. While
the outcome of these other lawsuits cannot be predicted with certainty,
management believes these other matters will not have a material adverse effect
on the consolidated financial position or results of operations of the Company.

  Advisory Agreement

     In February 1997, TCMS entered into an advisory agreement with a financial
advisory firm ("the firm") for a period of six months in connection with the
Acquisitions and related financings. Under the terms of the agreement between
the Company and the firm, as amended on June 25, 1997, TCMS paid the firm an
initial financial advisory fee of $15,000, plus monthly fees aggregating
$30,000, and reimbursed the firm for its out-of-pocket expenses relating to the
services provided. TCMS also issued a warrant to the firm for $100 in cash. The
warrant provides for the purchase of up to 50,000 shares of Common Stock, at a
per share exercise price equal to $8.00. The warrant may be exercised in whole
or, from time to time, in part, at any time during the five-year period
beginning six months after the Offering closes. In connection with the warrant,
TCMS granted certain registration rights to the firm.

     The firm received a $400,000 success fee upon the closing of the
Acquisitions and an $800,000 senior debt placement fee upon the closing of the
Credit Agreement. The firm is entitled to receive a private placement fee equal
to five percent of the amount of any private placement made by the Company
within two years of August 12, 1997 with any capital source introduced to the
Company by the firm, together with a warrant to purchase an amount equal to 10%
of the securities issued in any such private placement.

  Consulting Agreements

     During February 1997, TCMS entered into a consulting and financial advisory
agreement (the "Consulting Agreement") with a promoter of TCMS ("J&D"). The
Consulting Agreement provided for a monthly fee of $12,500 through the closing
of the Offering and was to provide for a monthly consulting fee and
non-qualified stock options under the 1997 Stock Option Plan. Shortly after the
Offering, the Consulting Agreement was terminated in exchange for the payment to
J&D of approximately $.8 million. In connection with the Consulting Agreement, a
total of 36,667 options were issued to J&D. The options expired concurrent with
the termination of the Consulting Agreement.

     In April 1997, TCMS entered into consulting services agreements with
certain officers of the Company. Pursuant to these agreements, the officers
provided executive services in connection with the formation of TCMS and the
closing of the Offering. Expenses related to these contract services totaled
$64,000 through the closing of the Offering, at which time these agreements
terminated.

  Employment Agreements

     In August 1997, TCMS entered into employment agreements with three officers
of the Company. Two of the agreements were effective August 1, 1997 and one upon
closing of the Offering. The term of the agreements extends three years
following the closing of the Offering. Additionally, the Company offered
employment agreements to certain members of management and key operating
personnel of the Founding Companies on similar terms and conditions to existing
agreements.

10. EMPLOYEE BENEFIT PLANS

     Woodson had an employee profit sharing plan (the "Plan") which provided for
contributions of up to 10 percent of the annual compensation of each
participant. The Plan includes employees of at least 21 years of age with one
year of completed service. Participants who became eligible after January 1,
1990 remain nonvested until the completion of five years of service, at which
time the participants become 100 percent vested. Woodson has obtained a
favorable tax determination letter from the Internal Revenue Service with
respect to the Plan. Woodson made Plan contributions of $30,000, $26,000 and
$59,000 for the years ended December 31, 1995, 1996 and 1997, respectively.

     Subsequent to December 31, 1997, the Plan was merged into the TCMS 401K
Plan, which was established effective January 1, 1998, for the benefit of its
employees. The Company has agreed to fund 50%
                                       40

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

per dollar of contribution by eligible employee, up to contributions totaling 6%
of the employee's annual salary. Employees of the Founding Companies were
eligible to commence participation in the TCMS 401K plan at either January 1 or
March 1, 1998, dependent upon the termination date of their specific benefit
plan.

11. SALES TO MAJOR CUSTOMERS

     The customer bases for the Company are primarily concentrated in the oil
and gas industry. The revenues earned from each customer vary from year to year
based on the contracts awarded. Sales to customers comprising 10% or more of the
Company's total revenues are summarized as follows:

13. SUBSEQUENT EVENTS

  Fabrication Facilities

     During the first quarter of 1998, the Company significantly expanded its
fabrication operations through two separate lease transactions. During January
1998, long-term lease rights were secured to a shipyard in the New Orleans,
Louisiana area capable of servicing deepwater drilling rigs, jack-ups,
semi-submersibles and drill ships. The lease term on this 29-acre yard is for
five years with committed lease payments totaling $0.2 million. During February
1998, the Company signed a long-term lease for a manufacturing facility located
on an 18-acre site in eastern New Orleans, Louisiana. The lease term is for
three years with committed lease payments totaling $.5 million.

  Vessel Acquisition

     During February 1998, the Company expanded its oil and gas pipeline
installation capabilities with the acquisition of the LB-207 pipelaying barge
(now renamed the Vermilion Bay). The purchase price was $8.0 million and was
financed through borrowings under the Credit Agreement. The Vermilion Bay is
expected to be available for service in the Gulf of Mexico by May 1998.

  Stock Option Grants

     During the first quarter of 1998, a total of 184,000 stock options were
granted to employees of TCMS, including members of management. The option price
was set at the market price on date of grant and ranged from $10.75 to $11.00.

  Cash Performance Bonus Plan

     During the first quarter of 1998, the Board of Directors approved a cash
performance bonus plan (the "Bonus Plan") for key management employees. The cash
performance bonus is based on three principal components, namely TCMS' overall
financial performance, the financial performance of each business unit, and the
performance of the individual employee. The Bonus Plan is effective for the
fiscal year commencing January 1, 1998.

               TRANSCOASTAL MARINE SERVICES, INC. AND SUBSIDIARY

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION

     TransCoastal Marine Services, Inc., a Delaware corporation ("TCMS"),
commenced operations in April 1996. TCMS intends to acquire four businesses (the
"Founding Companies") in separate transactions (collectively, the
"Acquisitions") simultaneously with an Offering (the "Offering") of its common
stock (the "Common Stock"). Unless otherwise indicated, all references herein to
the "Company" include the Founding Companies, and references herein to "TCMS"
mean TransCoastal Marine Services, Inc., prior to the consummation of the
Acquisitions.

     TCMS operations to date have related to the Offering and the Acquisitions.
All expenditures to date have been funded through loans from J&D Capital
Investments, L.C. ("J&D"). J&D is owned by two of the Company's founders. At
December 31, 1996, no costs had been incurred in connection with the Offering.
At June 30, 1997, approximately $462,000 has been incurred in connection with
the Offering. TCMS has accounted for these costs as deferred offering costs.
TCMS is dependent on the Offering to complete the pending Acquisitions and to
repay J&D. There is no assurance that the pending Acquisitions will be completed
or that the Company will be able to generate future operating revenues.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Principles of Consolidation

     The accompanying consolidated financial statements include the accounts of
TCMS and its wholly owned subsidiary, Red Fox International, Inc., a Louisiana
corporation. All significant intercompany accounts and transactions have been
eliminated in consolidation.

  Use of Estimates

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

  Income Taxes

     TCMS accounts for income taxes in accordance with Statement of Financial
Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes." Under SFAS
No. 109, the Company recognizes deferred tax liabilities and assets for the
expected future tax consequences of events that have been recognized differently
in the financial statements or tax returns. Under this method, deferred tax
liabilities and assets are determined based on the difference between the
financial statement carrying amounts and tax basis of assets and liabilities
using enacted tax rates and laws in effect in the years in which the differences
are expected to reverse. Deferred tax assets are evaluated for realization based
on a more-likely-than-not criteria in determining if a valuation allowance
should be provided. Income tax expense is the tax payable for the year and the
change during the year in deferred tax assets and liabilities.

  Recent Accounting Pronouncements

     SFAS No. 123, "Accounting for Stock-Based Compensation," allows entities to
choose between a new fair value-based method of accounting for employee stock
options or similar equity instruments and the current intrinsic, value-based
method of accounting prescribed by Accounting Principles Board ("APB") Opinion
No. 25. Entities electing to remain with the accounting in APB Opinion No. 25
must make pro forma disclosures of net income and earnings per share as if the
fair value method of accounting had been applied. TCMS has elected to account
for the issuance of stock options pursuant to APB Opinion No. 25 and will

                                       48
<PAGE>   51
               TRANSCOASTAL MARINE SERVICES, INC. AND SUBSIDIARY

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

provide pro forma disclosure of net income and earnings per share, as
applicable, in the notes to future consolidated financial statements.

     In February 1997, the Financial Accounting Standards Board issued SFAS No.
128, "Earnings Per Share." For the Company, SFAS No. 128 will be effective for
the year ended December 31, 1997. SFAS No. 128 simplifies the standards required
under current accounting rules for computing earnings per share and replaces the
presentation of primary earnings per share and fully diluted earnings per share
with a presentation of basic earnings per share ("basic EPS") and diluted
earnings per share ("diluted EPS"). Basic EPS excludes dilution and is
determined by dividing income available to common stockholders by the weighted
average number of common shares outstanding during the period. Diluted EPS
reflects the potential dilution that could occur if securities and other
contracts to issue common stock were exercised or converted into common stock.
Diluted EPS is computed similarly to fully diluted earnings per share under
current accounting rules. The implementation of SFAS No. 128 is not expected to
have a material effect on the Company's earnings per share as determined under
current accounting rules.

  Interim Financial Information

     The interim consolidated balance sheet as of June 30, 1997, and statements
of operations for the six months ended June 30, 1996 and 1997, are unaudited,
and certain information and footnote disclosures, normally included in financial
statements prepared in accordance with generally accepted accounting principles,
have been omitted. In the opinion of management, all adjustments, consisting
only of normal recurring adjustments, necessary to fairly present the
consolidated financial position, results of operations and cash flows with
respect to the interim financial statements have been included. The results of
operations for the interim periods are not necessarily indicative of the results
for the entire fiscal year.

3. SUMMARY OF FINANCING ARRANGEMENTS

     In February 1997, TCMS and J&D entered into an agreement providing for an
unsecured revolving credit facility (the "J&D Loan Agreement"), which was
amended in June 1997 to provide for borrowings up to $1.0 million, with interest
of 10 percent per annum due on the unpaid principal balance outstanding computed
from the date of each advance until maturity. Amounts outstanding under the J&D
Loan Agreement are due and payable on the earlier of June 19, 1998 or 30 days
following the successful completion of the Offering. As of June 30, 1997,
advances of $187,000 were outstanding.

4. SHAREHOLDERS' EQUITY

  Preferred Stock

     TCMS's Board of Directors is authorized to designate the voting power,
preferences, dividends, liquidation rights, redemption and other features
related to the TCMS's preferred stock. As of December 31, 1996 and June 30,
1997, no TCMS preferred stock had been issued.

  Common Stock

     TCMS effected a 1,000-for-one stock split in August 1997 of the outstanding
shares of Common Stock. In addition, TCMS increased the number of authorized
shares of Common Stock to 20,000,000 and authorized 3,000,000 shares of
restricted common stock ("Restricted Common Stock"). The effects of the stock
split and the increase in the shares of authorized Common Stock and Restricted
Common Stock have been retroactively reflected on the accompanying balance
sheets and in those notes.

     In March and April 1997, 175,000 shares and 100,000 shares of Common Stock,
respectively, were sold to management at $.001 per share. TCMS will record a
non-recurring, non-cash compensation charge of

                                       49
<PAGE>   52
               TRANSCOASTAL MARINE SERVICES, INC. AND SUBSIDIARY

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

$2.2 million effective with the closing of the Offering, representing the
difference between the amount paid for the shares and the estimated fair value
of the shares on the date of sale of such Common Stock.

     In April 1997, TCMS issued 3,000 shares of Common Stock to a consultant for
services performed in connection with the Offering. The $12,200 difference
between the amount paid and the estimated fair market value of the shares on the
date of issue was recorded as deferred offering costs in the second quarter of
1997. In July 1997, an additional 3,000 shares of Common Stock were issued with
the same terms to another consultant for services performed in connection with
the Offering. An additional $32,000 will be recorded as deferred offering costs
in the third quarter of 1997.

  Restricted Common Stock

     Shares of Restricted Common Stock, if issued, will have no voting rights.
Shares of Restricted Common Stock, if issued, would be convertible into shares
of Common Stock on a share-for-share basis (i) in the event of certain ownership
changes, (ii) 18 months after the Offering or (iii) in the event of approval by
a majority of holders of the Common Stock. As of December 31, 1996 and June 30,
1997, no Restricted Common Stock has been issued.

  Employee Stock Option Plan

     In August 1997, TCMS' stockholders approved the TCMS 1997 Stock Option Plan
(the "Plan"), which provides for the granting of stock options to directors,
executive officers, certain other employees and certain non-employee consultants
of the Company. The Plan permits the granting of options for up to 750,000
shares of Common Stock. The terms of the option awards will be established by
the compensation committee of the board of directors of TCMS. TCMS has granted
stock options to purchase an estimated 97,000 shares of Common Stock to certain
members of the executive management team of the Company. The number of shares
estimated to be issued is based upon 2.5 times the annual compensation of the
respective executives divided by the Offering price. These options will be
exercisable at an exercise price equal to the per share Offering price, vest
over a five-year period from the date of grant and expire 10 years from the date
of grant. Additionally, the Company expects to grant stock options to purchase
an estimated 360,000 shares of Common Stock to certain other members of
management and key operating personnel of the Founding Companies.

5. COMMITMENTS AND CONTINGENCIES

  Advisory Agreement

     In February 1997, the Company entered into an advisory agreement with a
financial advisory firm (the firm) for a period of six months in connection with
the Acquisitions and related financings. Under the terms of the agreement
between the Company and the firm, as amended on June 25, 1997, the Company paid
the firm an initial financial advisory fee of $15,000, plus monthly fees
aggregating $30,000, and reimbursed the firm for its out-of-pocket expenses
relating to the services provided. The Company also issued a warrant to the firm
for $100 in cash. The warrant provides for the purchase of up to 50,000 shares
of Common Stock, at a per share exercise price equal to the lesser of $8.00 or
70% of the Offering price. The warrant may be exercised in whole or, from time
to time, in part, at any time during the five-year period beginning six months
after the Offering closes. In connection with the warrant, the Company granted
certain registration rights to the firm.

     The firm will be entitled to receive the following fees in the future: (i)
a $400,000 success fee, payable on closing the Acquisitions; (ii) a senior debt
placement fee of up to 2% of a new credit agreement (the "Credit Agreement")
(see Note 6), payable on closing of the Credit Agreement; and (iii) a private
placement fee equal to five percent of the amount of any private placement made
by the Company within two years of

                                       50
<PAGE>   53
               TRANSCOASTAL MARINE SERVICES, INC. AND SUBSIDIARY

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

August 12, 1997 with any capital source introduced to the Company by the firm,
together with a warrant to purchase an amount equal to 10% of the securities
issued in any such private placement.

  Consulting Agreements

     In February 1997, TCMS entered into a consulting and financial advisory
agreement (the "Consulting Agreement") with J&D. The Consulting Agreement
provides for a monthly fee of $12,500, payable on the closing of the Offering
and terminates on the earlier of the closing of the Offering or December 31,
1997. All amounts incurred through June 30, 1997 were capitalized as deferred
offering costs. On September 24, 1997, TCMS and J&D amended the consulting
agreement, so that, following the completion of the Offering, J&D will provide
the Company financial advisory and related services in connection with its
acquisition program. J&D will receive a consulting fee of $23,500 per month and
non-qualified options under the 1997 Stock Option Plan, to purchase 44,000
shares (assuming an Offering price of $15.00 per share) for an exercise price
equal to the Offering price per share. These options will vest at the rate of
20% per year, commencing on the first anniversary of the closing of the
Offering, and will expire at the earlier of ten years from the date of grant or
three months following termination of the consulting and financial services
agreement. In addition, J&D will be eligible to receive annual performance-based
bonuses.

     In April 1997, TCMS entered into consulting services agreements with
certain officers of the Company. Pursuant to these agreements, the officers will
provide executive services in connection with the formation of TCMS and the
closing of the Offering. Expenses related to these contract services are
estimated to be approximately $30,000 per month until the date the Offering
closes, at which time these agreements automatically terminate.

  Employment Agreements

     In August 1997, TCMS entered into employment agreements with three officers
of the Company. Two of the agreements are effective August 1, 1997 and one upon
closing of the Offering. The term of the agreements extends three years
following the closing of the Offering. Additionally, the Company is committed to
offer employment agreements to certain members of management and key operating
personnel of the Founding Companies on similar terms and conditions to existing
agreements.

6. SUBSEQUENT EVENTS

  Acquisitions

     The Company has entered into definitive agreements to acquire the Founding
Companies and related real estate on the date the Offering closes. The Founding
Companies are The Woodson Companies, The CSI Companies, HBH, Inc. and The Red
Fox Companies of New Iberia, Inc. The aggregate consideration expected to be
paid by TCMS to acquire the Founding Companies is approximately $85,650,000 in
cash, $3,000,000 in debt and 2,570,933 shares of Common Stock (including certain
estimated post-closing adjustments). In addition, the Company will be assuming
debt on certain of the Founding Companies.

  Credit Agreement

     Prior to the closing of the Offering, TCMS intends to enter into the Credit
Agreement with Joint Energy Development Investments, Limited Partnership, an
affiliate of Enron Capital & Trade Resources Corp. (the "Lender"). TCMS expects
that the Credit Agreement will provide for borrowings up to $75.0 million, with
the initial borrowing availability being $50.0 million (the "Initial
Availability") and the remaining $25.0 million being made available from time to
time and in such amounts as the Lender shall determine in its sole discretion.
The Credit Agreement will be divided into two tranches: (i) a senior secured
revolving credit facility (the "Revolving Credit Facility"), providing for
borrowings of up to $60.0 million ($40.0 million of

                                       51
<PAGE>   54
               TRANSCOASTAL MARINE SERVICES, INC. AND SUBSIDIARY

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

which will comprise part of the Initial Availability), and (ii) $15.0 million of
senior subordinated term loan borrowings (the "Term Loan Facility") ($10.0
million of which will comprise the remainder of the Initial Availability). The
Company also expects (i) borrowings under the Credit Agreement will bear
interest at LIBOR plus 275 basis points (8.37% at October 3, 1997), payable
quarterly, and (ii) borrowings under the Term Loan Facility will bear interest
at LIBOR plus 375 basis points (9.37% at October 3, 1997), payable quarterly.
Borrowings under the Credit Agreement will be secured by liens on substantially
all the Company's assets (including accounts receivable and after-acquired
property) and a pledge of the capital stock of the Founding Companies and each
of the Company's other subsidiaries. Borrowings under the Credit Agreement are
expected to be used to pay a portion of the aggregate purchase price for the
Acquisitions and for general corporate purposes, which may include future
acquisitions. The Company expects that the Credit Agreement will require the
Company to comply with various loan covenants, including (i) maintenance of
certain financial ratios; (ii) restrictions on additional indebtedness; and
(iii) restrictions on liens, guarantees, advances and dividends. The Company
anticipates the Credit Agreement will extend through October 1999 and all
outstanding principal and accrued and unpaid interest under the Revolving Credit
Facility and the Term Loan Facility as of that date will be due and payable on
that date. The Company also anticipates the Credit Agreement will contain
mandatory prepayment provisions requiring prepayment of outstanding borrowings
from the issuance of debt or equity securities for cash and any proceeds from
other borrowings. In connection with the Credit Agreement, the Company will
issue to the Lender a warrant to acquire 175,000 shares of Common Stock at an
exercise price equal to the initial per share price to the public in the
Offering. The consideration for that warrant will be $1,750 and the warrant is
expected to be exercisable for five years from its date of issuance.

  Registration Statement

     In August 1997, the Company filed a registration statement on Form S-1 for
the Offering. An investment in shares of Common Stock involves a high degree of
risk, including, among others, absence of a combined operating history, risks
relating to the Company's acquisition strategy, risks relating to acquisition
financing, reliance on key personnel and a substantial portion of the proceeds
from the Offering payable to affiliates of the Founding Companies.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To The Woodson Companies:

     We have audited the accompanying combined balance sheets of The Woodson
Companies (as defined in Note 1) as of December 31, 1995 and 1996, and the
related combined statements of operations, shareholders' equity and cash flows
for the three years in the period ended December 31, 1996. These financial
statements are the responsibility of the management of The Woodson Companies.
Our responsibility is to express an opinion on these combined financial
statements based on our audits.

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

     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of The Woodson
Companies as of December 31, 1995 and 1996, and the combined results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1996, in conformity with generally accepted accounting principles.

                             THE WOODSON COMPANIES

                     NOTES TO COMBINED FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION

  Principles of Combination

     The accompanying combined financial statements include the accounts of the
following corporations, all headquartered in Lafayette, Louisiana, which are
related by the common ownership of immediate family members:

        Woodson Construction Company, Inc. (WCC)
        Laine Construction Company, Inc. (Laine)
        Kori Corporation (Kori)
        EnviroSystems, Inc. (Enviro)

     Financial statements for the aforementioned companies (collectively, "The
Woodson Companies" or the "Companies") have been prepared on a combined basis
due to the Companies' common ownership by immediate family members acting as a
control group.

  Description of Operations

     WCC and Laine are in the business of constructing pipelines for the oil and
gas industry primarily offshore Louisiana, Texas, Mississippi and Alabama. WCC
secures contracts with customers and subcontracts substantially all the work to
Laine, which is owned by several officers of WCC.

     Kori manufactures amphibious undercarriages for use primarily in marine
construction in the transition zone (from zero to 20 feet in depth). As an
Original Equipment Manufacturer ("OEM"), Kori supplies amphibious undercarriages
to companies that manufacture and/or distribute excavators

     Enviro performs sight assessments and on-site remediation of
petroleum-based products. Enviro also assists customers in the preparation and
submission of applications for reimbursement to the Louisiana Department of
Environmental Quality. All of Enviro's revenue is derived from sources within
the State of Louisiana.

     Although the Companies have experienced growth in revenue over the past few
years, there is an inherent concentration of credit risk associated with
contracts receivable from their major customers. At December 31, 1995 and 1996,
two customers comprised approximately 42 percent and 61 percent, respectively,
of the total contracts receivable balance. As the Companies have historically
funded their operations with cash flows from operations, the combined entity may
be impacted by its dependence on a limited number of customers. Management
believes the risk is mitigated by the long-standing business relationships with
and reputation of the Companies' major customers. Although there is no assurance
with regard to the future business associations between the Companies and their
major customers, management believes the Companies do not have a significant
concentration of risk at December 31, 1995 and 1996. See Note 13 for a summary
of sales to major customers.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Use of Estimates

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

                             THE WOODSON COMPANIES

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

  Cash and Cash Equivalents

     Cash equivalents consist of highly liquid debt instruments purchased with
original maturities of three months or less.

  Inventory

     Inventories represent raw materials and production supplies and are stated
at cost using the specific-identification method. Cost is not in excess of
market. At December 31, 1995 and 1996, the amount of inventory (including
materials and work-in-process) held was approximately $179,000 and $243,000,
respectively. Work-in-process inventory historically has not been significant.

  Property, Plant and Equipment

     Property, plant and equipment is stated at cost less accumulated
depreciation. Depreciation is computed using the straight-line and accelerated
methods based on the estimated useful lives of the assets, which range from five
to 31.5 years. Additions, improvements and renewals significantly adding to the
asset value or extending the life of the asset are capitalized. Ordinary
maintenance and repairs which do not extend the physical or economic lives of
the plant or equipment are charged to expense as incurred (see Note 5 for a
summary of property, plant and equipment).

  Revenue Recognition

     Revenues from construction contracts, which are typically of short
duration, are recognized on the percentage-of-completion method. Under this
method, the percentage of completion is determined by comparing contract costs
incurred to date with total estimated contract costs. Income is recognized by
applying the percentage complete to the projected total income for each contract
in progress. Contract costs include all direct material, labor and subcontract
costs and those indirect costs related to contract performance, such as indirect
labor, supplies and tools. Revisions in cost and income estimates are reflected
in the accounting period in which the facts requiring revision become known. In
addition, anticipated losses to be incurred on contracts in progress are charged
to income as soon as such losses can be determined.

  Fair Value of Financial Instruments

     The Woodson Companies consider the fair value of all financial instruments
to not be materially different from their carrying values at each year-end based
on management's estimate of the Companies' ability to borrow funds under terms
and conditions similar to those applicable to the Companies' existing debt.

  Income Taxes

     The Companies account for income taxes in accordance with Statement of
Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes."
Under SFAS No. 109, the Companies recognize deferred tax liabilities and assets
for the expected future tax consequences of events recognized differently in the
financial statements or tax returns. Under this method, deferred tax liabilities
and assets are determined based on the difference between the financial
statement carrying amounts and tax basis of assets and liabilities using enacted
tax rates and laws in effect in the years in which the differences are expected
to reverse. Deferred tax assets are evaluated for realization based on a
more-likely-than-not criteria in determining if a valuation allowance should be
provided. Income tax expense is the tax payable for the year and the change
during the year in deferred tax assets and liabilities.

     The Woodson Companies' shareholders have elected to have two of the
combined companies (Laine and Enviro) taxed as S Corporations for federal and
state income tax purposes whereby shareholders are liable for individual federal
and state income taxes on their allocated portions of the applicable entity's
taxable income.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

Accordingly, the historical financial statements do not include provisions for
income taxes relating to those entities.

     Pro forma net income (loss) consists of the historical net income (loss) of
the Companies, including two S Corporations, adjusted for income taxes that
would have been recorded had each company operated as a C Corporation.

  Recent Accounting Pronouncements

     In March 1995, the Financial Accounting Standards Board issued SFAS No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of." SFAS No. 121 requires that long-lived assets and
certain identifiable intangibles to be held and used by an entity be reviewed
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. The Woodson Companies
adopted SFAS No. 121 on January 1, 1996. The impact of adopting this standard
did not have a material impact on the Companies' combined results of operations.

  Interim Financial Information

     The interim combined balance sheet as of June 30, 1997 and combined
statements of operations for the six months ended June 30, 1996 and 1997 are
unaudited, and certain information and footnote disclosures, normally included
in financial statements prepared in accordance with generally accepted
accounting principles, have been omitted. In the opinion of management, all
adjustments, consisting only of normal recurring adjustments, necessary to
fairly present the financial position, results of operations and cash flows with
respect to the interim combined financial statements have been included. The
results of operations for the interim periods are not necessarily indicative of
the results for the entire fiscal year.

</TABLE>

     The portion of the retainage due in excess of one year is not significant.

     The Woodson Companies' accounts receivable balances as of December 31, 1995
and 1996 were approximately $343,000 and $103,000, respectively. The Woodson
Companies charge uncollectible receivables (contracts and accounts) to expense
when available information indicates that it is probable that the assets have
been impaired. Bad debt expense amounted to $217,000, $4,000 and $-- for the
years ended December 31, 1994, 1995 and 1996, respectively.

     During December 1996, the Companies issued three unsecured promissory notes
to their shareholders, payable on demand and bearing interest at 8 percent. The
balance on the notes payable to the shareholders at December 31, 1996, was
$450,000.

     The companies lease office space from certain of their shareholders. The
amount recorded as expense related to this lease was $142,200 for each of the
three years ended December 31, 1994, 1995 and 1996.

     In addition to the above transactions, WCC sold certain buildings, land and
improvements during the years ended December 31, 1995 and 1996 to companies

10. RETIREMENT PLAN

     The Woodson Companies Employee Profit Sharing Plan ("the Plan") provides
for contributions of up to 10 percent of the annual compensation of each
participant. The Plan includes employees of at least 21 years of age with one
year of completed service. Participants who became eligible after January 1,
1990 remain nonvested until the completion of five years of service, at which
time the participants become 100 percent vested. The Companies have obtained a
favorable tax determination letter from the Internal Revenue Service with
respect to the Plan.

     The Woodson Companies made Plan contributions of $--, $30,000 and $26,000
for the years ended December 31, 1994, 1995 and 1996, respectively.

12. COMMITMENTS AND CONTINGENCIES

  Insurance

     The Woodson Companies are subject to numerous risks and uncertainties
because of the nature and status of their operations. The Woodson Companies
maintain insurance coverage for events and in amounts that they deem
appropriate. With the exception of certain uninsured punitive damage claims
which cannot reasonably be estimated at this time as described under the heading
"Litigation," management believes that uninsured losses, if any, will not be
materially adverse to the Companies' financial position or results of
operations.

     The Woodson Companies maintain a self-insurance program for their workers'
compensation claims. The insurance carrier requires the Companies to retain
$81,000 in a money market account and a $37,000 escrow fund, which the Companies
have included in other assets in the accompanying balance sheets. The program
provides for self-insurance coverage of $10,000 per occurrence, subject to a
maximum exposure of $50,000 per year. No expenses were accrued relative to the
self-insurance program for the periods shown in the statements of operations.

  Litigation

     The Companies are currently involved in two class action lawsuits for
unspecified personal injury and property damages arising from events in October
1991 and January 1992 during the course of a pipeline installation project for a
third party gas transmission company. One of the class actions, involving
approximately 9,840 class members, entitled Rivera v. United Gas Pipeline
Co.,No. 28738, was instituted against Woodson Construction Company, Inc. on
October 29, 1991 in the 40th Judicial District Court, Parish of St. John the
Baptist, State of Louisiana, and the other class action, involving approximately
7,858 class members, entitled Husseiney v. United Gas Pipeline Co., No. 29089,
was instituted on January 27, 1992 against Woodson Construction Company, Inc. in
the 40th Judicial District Court, Parish of St. John the Baptist, State of
Louisiana. The claims of 24 representative class members in each case were tried
in 1995, and judgments were rendered against Woodson Construction Company, Inc.,
which were later affirmed by the court of appeal. In the Rivera lawsuit, five of
the 24 representative plaintiffs were awarded compensatory damages of $7,500 in
the aggregate, but punitive damages were denied. In the Husseiney lawsuit,
compensatory damages of $18,589 and punitive damages of $9,500 in the aggregate
were assessed against Woodson Construction Company, Inc. in favor of 16 of the
24 representative plaintiffs. In both lawsuits, the compensatory damages awarded
are expected to be covered by the Companies' insurance, but punitive damage
awards are not expected to be covered by insurance. The compensatory and
punitive damages awarded to the 16 representative class members varied according
to the representatives' proximity to the incident and individual experience with
respect to it. The amount of compensatory and punitive damages applicable to the
remaining 7,834 class members who seek to adjudicate their damage claims will be
litigated on an individual basis. Until those remaining damage claims are
finally adjudicated, settled, dismissed or otherwise terminated, the total
amount of the punitive damages to which the Companies may be subject cannot
reasonably be estimated, and there can be no assurance that it will not be
materially adverse to the Woodson Companies' financial position or results of
operations. In July 1997, all parties involved applied to the Louisiana Supreme
Court for further discretionary review of the existing judgments. The Companies
believe that there are meritorious arguments favorable to their position, but
are unable to predict whether the Louisiana Supreme Court will grant relief from
the judgments.

     The Companies are involved in various other lawsuits arising in the
ordinary course of business, some of which involve substantial claims for
damages. While the outcome of these other lawsuits cannot be predicted with
certainty, management believes these other matters will not have a material
adverse effect on the combined financial position or results of operations of
the Companies.

14. SUBSEQUENT EVENTS

     The Woodson Companies and their shareholders expect to enter into
definitive agreements with TransCoastal Marine Services, Inc. ("TCMS"), pursuant
to which all the outstanding shares of the common stock of WCC, Kori and Enviro
will be acquired for TCMS common stock in three separate merger transactions,
and all the outstanding shares of the common stock of Laine will be purchased
for cash and shares of TCMS common stock concurrently with the closing of the
Offering (the "Offering") of the common stock of TCMS.

     Shortly before the closing of the Offering, the Companies' shareholders
will elect to terminate the status as an S corporation for Laine and Enviro and
those companies will become subject to federal and state income taxes. Prior to
their termination as S corporations, subject to the terms of the acquisition
agreements, the Companies must refrain from declaring or paying any dividends or
Subchapter S distributions to any shareholders, directors, management sales
agents, employees or other personnel, except for dividends and distributions to
shareholders paid or declared in 1997 which in the aggregate do not exceed 43.2%
of the Companies' pretax income during 1997 excluding certain other mutually
agreed-to distributions, through the earlier of September 30, 1997 or the
Closing Date.

     We have audited the accompanying combined balance sheets of The CSI
Companies (as defined in Note 1), as of December 31, 1995 and 1996, and the
related combined statements of operations, owners' equity and cash flows for
each of the two years in the period ended May 31, 1995, the seven months ended
December 31, 1995, and the year ended December 31, 1996. These financial
statements are the responsibility of the management of The CSI Companies. Our
responsibility is to express an opinion on these combined financial statements
based on our audits.

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

     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of The CSI
Companies, as of December 31, 1995 and 1996, and the combined results of their
operations and their cash flows for each of the two years in the period ended
May 31, 1995, the seven months ended December 31, 1995 and the year ended
December 31, 1996, in conformity with generally accepted accounting principles.

                               THE CSI COMPANIES

                     NOTES TO COMBINED FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION

  Principles of Combination

     The accompanying combined financial statements include the accounts of the
following companies, all headquartered in Lafayette, Louisiana, which are
related by the common ownership of a major shareholder and immediate family
members:

        CSI Hydrostatic Testers, Inc. (CSI) and its wholly owned subsidiary,
         Blue-Water Hydro Test

        Corporation (Blue-Water)

        Hargett Mooring and Marine, Inc. (HMMI)

        Hargett Investments LLC (HI)

     Financial statements for the aforementioned companies ("The CSI Companies"
or the "Companies") have been prepared on a combined basis due to the Companies'
common ownership.

  Description of Operations

     CSI is primarily engaged in testing offshore oil and gas pipelines and
providing sandblasting and painting services to companies in the oil and gas
industry. CSI's main operating area is in and around the Gulf of Mexico.
Blue-Water had no operations as of December 31, 1996. HMMI is a marine vessel
company, focused on chartering vessels for certain energy-related services. HI's
operations consist of leasing office space to CSI.

     Although the Companies have experienced growth in revenue over the past few
years, there is an inherent concentration of credit risk associated with
contracts receivable from their major customers. At December 31, 1995 and 1996,
two customers comprised approximately 55 percent and three customers comprised
approximately 45 percent, respectively, of the total accounts receivable
balance. As the Companies have historically funded their operations with cash
flows from operations, the combined entity may be impacted by its dependence on
a limited number of customers. Management believes the risk is mitigated by the
long-standing business relationship with and reputation of the Companies' major
clients. Although there is no assurance with regard to the future business
associations between the Companies and their major customers, management
believes the Companies do not have a significant concentration of risk at
December 31, 1995 and 1996. See Note 12 for a summary of sales to major
customers.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Use of Estimates

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

  Cash and Cash Equivalents

     Cash equivalents consist of highly liquid debt instruments purchased with
original maturities of three months or less.

  Restricted Cash

     Restricted cash represents cash equivalent investments to support letters
of credit established by the Companies in the normal course of business with
certain vendors.

                               THE CSI COMPANIES

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

  Property, Plant and Equipment

     Property, plant and equipment is stated at cost less accumulated
depreciation. Depreciation is computed using the straight-line and accelerated
methods based on the estimated useful lives of the assets, which range from
three to 30 years. Additions, improvements and renewals significantly adding to
the asset value or extending the life of the asset are capitalized. Ordinary
maintenance and repairs which do not extend the physical or economic lives of
the plant or equipment are charged to expense as incurred.

  Revenue Recognition

     The Companies follow the percentage-of-completion method of accounting for
construction contracts which are typically of short duration. Under this method,
the percentage of completion is determined by comparing contract costs incurred
to date with total estimated contract costs. Income is recognized by applying
the percentage complete to the projected total income for each contract in
progress. Contract costs include all direct material, labor and subcontract
costs and those indirect costs related to contract performance, such as indirect
labor, supplies and tools. Revisions in cost and income estimates are reflected
in the accounting period in which the facts requiring revision become known. In
addition, anticipated losses to be incurred on contracts in progress are charged
to income as soon as such losses can be determined. With regard to pipeline
testing services performed, the companies recognize revenues on an as-billed
basis, with an accrual made at each period end for unbilled revenue.

  Fair Value of Financial Instruments

     The CSI Companies consider the fair value of all financial instruments to
not be materially different from their carrying values at each year-end based on
management's estimate of the Companies' ability to borrow funds under terms and
conditions similar to those applicable to the Companies' existing debt.

  Income Taxes

     The Companies account for income taxes in accordance with Statement of
Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes."
Under SFAS No. 109, the Companies recognize deferred tax liabilities and assets
for the expected future tax consequences of events that have been recognized
differently in the financial statements or tax returns. Under this method,
deferred tax liabilities and assets are determined based on the difference
between the financial statement carrying amounts and tax basis of assets and
liabilities using enacted tax rates and laws in effect in the years in which the
differences are expected to reverse. Deferred tax assets are evaluated for
realization based on a more-likely-than-not criteria in determining if a
valuation allowance should be provided. Income tax expense is the tax payable
for the year and the change during the year in deferred tax assets and
liabilities.

     One of the combining entities, HI, is a limited liability corporation. Its
members are liable for individual federal and state income taxes on their
allocated portions of its taxable income. Accordingly, the historical financial
statements do not include provisions for income taxes relating to HI.

     Pro forma net income (loss) consists of the historical net income (loss) of
the Companies', including HI, a limited liability corporation, adjusted for
income taxes that would have been recorded had each Company operated as a C
corporation.

  Recent Accounting Pronouncements

     In March 1995, the Financial Accounting Standards Board issued SFAS No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of." SFAS No. 121 requires that long-lived assets and
certain identifiable intangibles to be held and used by an entity be reviewed
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may

not be recoverable. The Companies adopted SFAS No. 121 on January 1, 1996. The
impact of adopting this standard did not have a material impact on the combined
results of operations.

  Interim Financial Information

     The interim combined balance sheet as of June 30, 1997 and combined
statements of operations for the six months ended June 30, 1996 and 1997 are
unaudited, and certain information and footnote disclosures, normally included
in financial statements prepared in accordance with generally accepted
accounting principles, have been omitted. In the opinion of management, all
adjustments, consisting only of normal recurring adjustments, necessary to
fairly present the financial position, results of operations and cash flows with
respect to the interim combined financial statements have been included. The
results of operations for the interim periods are not necessarily indicative of
the results for the entire fiscal year.

  Litigation

     The CSI Companies are involved in various legal actions incidental to the
ordinary course of business. A former employee brought one such lawsuit against
HMMI in 1991. The former employee alleged personal injury while in the course
and scope of his employment and submitted an opening settlement demand of
$700,000. The case is currently pending trial in state district court. In the
opinion of the Companies' management, after consultation with outside legal
counsel, the ultimate disposition of such proceedings, including the case above,
will not have a material adverse effect on the Companies' financial position or
results of operations.

assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of HBH, Inc. as of December 31,
1995 and 1996, and the results of its operations and its cash flows for each of
the three years in the period ended December 31, 1996, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION

     HBH, Inc. (the "Company"), is wholly owned by the Estate of H.D. Hughes.
The Company is engaged in the marine pipeline and oilfield construction business
in the central area of the Gulf of Mexico.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Use of Estimates

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

  Cash and Cash Equivalents

     Cash equivalents consist of highly liquid debt instruments purchased with
original maturities of three months or less.

  Accounts Receivable

     The Company provides its services to a limited number of customers. At
December 31, 1996, five customers accounted for approximately 19%, 18%, 14%, 14%
and 13% of accounts receivable, respectively.

     Accounts receivable are reduced by any allowance for doubtful accounts as
considered necessary. The need for an allowance is determined by management
based on an evaluation of individual accounts. Historical chargeoffs have not
been significant.

  Property, Plant and Equipment

     Property, plant and equipment is stated at cost less accumulated
depreciation. Depreciation is computed using the straight-line method based on
the estimated useful lives of the assets, which range from 3 to 10 years for
machinery and equipment and other assets. Additions, improvements and renewals
significantly adding to the asset value or extending the life of the asset are
capitalized. Ordinary maintenance and repairs not extending the physical or
economic lives of the plant or equipment are charged to expense as incurred.

  Revenue Recognition

     The Company follows the percentage-of-completion method of accounting for
major (generally over $100,000) construction contracts which are typically of
short duration. Under this method, the percentage of completion is determined by
comparing contract costs incurred to date with total estimated contract costs.
Income is recognized by applying the percentage complete to the projected total
income for each contract in progress. Contract costs include all direct
material, labor and subcontract costs and those indirect costs related to
contract performance, such as indirect labor, supplies and tools. Revisions in
cost and income estimates are reflected in the accounting period in which the
facts requiring the revision become known. In addition, anticipated losses to be
incurred on contracts in progress are charged to income as soon as losses can be
determined.

     Revenue is recognized on minor construction contracts using the
completed-contract method whereby billings and costs are accumulated during the
period of construction but profits are not recorded until completion of the
contracts. This method approximates the percentage of completion method because
of the short-term nature of the minor contracts.

                                       84
<PAGE>   87
                                   HBH, INC.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     Revenues from day-rate contracts are recognized currently as the work is
performed.

  Fair Value of Financial Instruments

     The Company considers the fair value of all financial instruments to be a
reasonable approximation of their carrying values since financial instruments
such as cash, accounts receivable, accounts payable and accrued expenses have a
short duration and interest on debt is generally either at a floating rate or at
a rate which approximates current market.

  Income Taxes

     The Company has elected to be taxed for federal and state income tax
purposes under Subchapter S of the Internal Revenue Code. Any current taxable
income or loss of the Company is allocated to the shareholder who is responsible
for the taxes thereon.

     The Company generally has paid dividends to its shareholder at the same
time that he was required to make income tax payments based on his taxable
income which included the results of the Company's operations.

     Pro forma net income (loss) consists of the Company's historical income
(loss) as an S Corporation, adjusted for income taxes that would have been
recorded had the Company operated as a C Corporation.

  Impairment of Long-Lived Assets

     In March 1995, the Financing Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 121, "Accounting for Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." SFAS No. 121
requires that long-lived assets and certain identifiable intangibles to be held
and used by an entity be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. The Company adopted SFAS No. 121 on January 1, 1996. The impact of
adopting this standard did not have a material impact on the Company's results
of operations.

  Interim Financial Information

     The interim financial statements as of June 30, 1997 and for the six months
ended June 30, 1996 and 1997 are unaudited, and certain information and footnote
disclosures, normally included in annual financial statements prepared in
accordance with generally accepted accounting principles, have been omitted. In
the opinion of management, all adjustments, consisting only of normal recurring
adjustments, necessary to fairly present the financial position, results of
operations and cash flows with respect to the interim financial statements have
been included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.

     Amounts due from the Company's sole shareholder in the form of notes
receivable amounted to $194,000 at December 31, 1996 and $1,103,000 at December
31, 1995, at various interest rates ranging up to 9%. Interest income on these
notes was approximately $44,000 for the year ended December 31, 1996, $101,000
for the year ended December 31, 1995 and $117,000 for the year ended December
31, 1994.

     Land and buildings were sold to the Company's sole shareholder in October
1983. The excess of the sales price over the carrying value of the property was
deferred and was being recognized as payments were received on the note. During
1996, the remaining balance of the note was collected and the remaining gain of
$508,000 was recognized as income. The Company is leasing this property from the
shareholder on a month-to-month basis. Rent expense amounted to $167,000 for
each of 1996, 1995 and 1994.

     The subordinated debt is due to the shareholder and is subordinate to the
revolving line of credit. The note bears interest at 9.45 percent, and interest
only is due in monthly installments through June 11, 2001, at which time the
terms of repayment of interest and principal are to be renegotiated.

     The Company paid consulting, debt guarantee and other fees to the Company's
sole shareholder through December 31, 1996. These fees aggregated $233,000 for
each of 1996, 1995 and 1994.

8. COMMITMENTS AND CONTINGENCIES

     The Company is a party to various legal proceedings arising in the ordinary
course of business and is not aware of any litigation threatened against it that
could have a material effect on the financial statements.

9. SUBSEQUENT EVENTS (UNAUDITED)

     In June 1997, the maturity date of the revolving line of credit was
extended until June 16, 1998.

     The Company and its shareholder have entered into a definitive agreement
(being held in escrow subject to the satisfaction of certain conditions) with
TransCoastal Marine Services, Inc. ("TCMS"), pursuant to which all the
outstanding shares of the Company's common stock will be sold to TCMS for cash
and shares of TCMS common stock concurrently with the consummation of the
Offering (the "Offering") of the common stock of TCMS.

     A sale of the stock as described above would automatically terminate the
Company's status as an S corporation. Under the terms of the definitive
agreement, the Company has agreed to restrictions upon dividends or S
corporation distributions.

10. SALES TO MAJOR CUSTOMERS

     The customer base for the Company is primarily concentrated in the oil and
gas industry. The revenue earned from each customer varies from year to year

To The Red Fox Companies of New Iberia, Inc.:

     We have audited the accompanying balance sheets of The Red Fox Companies of
New Iberia, Inc., as of December 31, 1995 and 1996, and the related statements
of operations, shareholder's equity and cash flows for the three years in the
period ended December 31, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of The Red Fox Companies of New
Iberia, Inc., as of December 31, 1995 and 1996, and the results of its
operations and its cash flows for each of the three years in the period ended

                   THE RED FOX COMPANIES OF NEW IBERIA, INC.

                       NOTES TO THE FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION

     The Red Fox Companies of New Iberia, Inc. (the "Company") is primarily
engaged in the fabrication and refurbishment of (i) structural components of
fixed platforms for use in the development of oil and gas, and (ii) structural
components, primarily deck structures, for offshore drilling rigs and barge
drilling rigs. RFCNI also fabricates marine sewage treatment units that are
installed on offshore platforms and drilling rigs.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Use of Estimates

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

  Cash and Cash Equivalents

     Cash equivalents consist of highly liquid debt instruments purchased with
original maturities of three months or less.

  Contracts Receivable

     The Company provides for doubtful accounts using the direct write-off
method. In the Company's case, use of this method does not result in a material
difference from the valuation method required by generally accepted accounting
principles.

  Property, Plant and Equipment

     Property, plant and equipment is stated at cost. Depreciation expense is
computed using the straight-line method based on the estimated useful lives of
the assets, which range from five to seven years. Additions, improvements and
renewals significantly adding to the asset value or extending the life of the
asset are capitalized. Ordinary maintenance and repairs not extending the
physical or economic lives of the plant or equipment are charged to expense as
incurred.

  Revenue Recognition

     Revenue from construction contracts, which are typically of short duration,
are recognized on the percentage-of-completion method. Under this method, the
percentage of completion is determined by comparing contract costs incurred to
date with total estimated contract costs. Income is recognized by applying the
percentage complete to the projected total income for each contract in progress.
Contract costs include all direct material, labor and subcontract costs and
those indirect costs related to contract performance, such as indirect labor,
supplies and tools. Revisions in cost and income estimates are reflected in the
accounting period in which the facts that require revision become known. In
addition, anticipated losses to be incurred on contracts in progress are charged
to income as soon as such losses can be determined.

     The asset caption entitled "Costs and estimated earnings in excess of
billings on uncompleted contracts" represents revenue recognized in excess of
amounts billed. The liability caption entitled "Billings in excess of costs and
estimated earnings on uncompleted contracts" represents billings in excess of
revenue recognized.

  Fair Value of Financial Instruments

     The Company considers the fair value of all financial instruments to not be
materially different from their carrying values at December 31, 1995 and 1996.

                                       94

                   THE RED FOX COMPANIES OF NEW IBERIA, INC.

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)

  Income Taxes

     The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes."
Under SFAS No. 109, the Company recognized deferred tax liabilities and assets
for the expected future tax consequences of events that have been recognized
differently in the financial statements or tax returns. Under this method,
deferred tax liabilities and assets are determined based on the difference
between the financial statement carrying amounts and tax basis of assets and
liabilities using enacted tax rates and laws in effect in the years in which the
differences are expected to reverse. Deferred tax assets are evaluated for
realization based on a more-likely-than-not criteria in determining if a
valuation allowance should be provided. Income tax expense is the tax payable
for the year and the change during the year in deferred tax assets and
liabilities.

  Recent Accounting Pronouncements

     In March 1995, the Financial Accounting Standards Board issued SFAS No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of." SFAS No. 121 requires long-lived assets and certain
identifiable intangibles to be held and used by an entity be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. The Company adopted SFAS No.
121 on January 1, 1996. The impact of adopting this standard did not have a
material impact on the results of operations.

  Interim Financial Information

     The interim balance sheet as of June 30, 1997 and statements of operations
for the six months ended June 30, 1996 and 1997 are unaudited, and certain
information and footnote disclosures, normally included in financial statements
prepared in accordance with generally accepted accounting principles, have been
omitted. In the opinion of management, all adjustments, consisting only of
normal recurring adjustments, necessary to fairly present the financial
position, results of operations and cash flows with respect to the interim
financial statements have been included. The results of operations for the
interim periods are not necessarily indicative of the results for the entire
fiscal year.

     Actual income tax expense differs from income tax expense computed by
applying the U.S. federal statutory corporate rate of 34 percent to income
(loss) before income taxes as follows:
