PART I

ITEM 1. BUSINESS
GENERAL

Cal Dive International, Inc. ("CDI" or the "Company") is a leading subsea
contractor providing services from the shallowest to the deepest waters in the
Gulf of Mexico. Over three decades, CDI has developed a reputation for
innovation in underwater construction techniques and equipment. With its
diversified fleet of 11 vessels and access to barges under its alliance with
Horizon Offshore Inc. ("Horizon"), CDI performs services which cover the life of
an offshore natural gas or oil field. Through its subsidiary, Energy Resource
Technology, Inc. ("ERT"),it acquires mature offshore properties to provide
customers a cost effective alternative to the decommissioning process. The
Company's customers include major and independent natural gas and oil producers,
pipeline transmission companies and offshore engineering and construction firms.

In water depths up to 1,000 feet ("OCS"), CDI is a dominant provider of
subsea services which include air and SAT diving in support of marine
construction activities. Each of the Company's 11 vessels perform these
services, six of which support SAT diving. CDI owns a large minority share in
Aquatica, Inc., a new shallow water diving company, which grew significantly in
1998. CDI also has a new service beginning in 1999 which involves a methodology
for shallow water full field development designed to reduce new field cost and
completion time.

Activity in Gulf water depths greater than 1,000 feet (the "Deepwater")
involves technological challenges which have required subsea contractors to
develop new technology. With a fleet of four Deepwater-capable vessels, CDI has
assembled a technically diverse fleet permanently deployed in the Gulf for the
delivery of these subsea solutions. CDI has formed alliances with other offshore
service and equipment providers which enhance its ability to provide full field
and life of field services, including a strategic alliance with Coflexip, a
world leader serving the Deepwater market. CDI is also developing a new
Deepwater construction vessel, the Q4000 and assisting industry groups to
develop new technology to solve challenges of Deepwater projects which can be
deployed from its DP vessels.

OFFSHORE Magazine recently affirmed Cal Dive as the number one player in
the decommissioning market as CDI was responsible for 24% of the structures
removed from the Gulf during the years 1996 through mid-1998. CDI's alliance
with Horizon provides access to expanded derrick and heavy lift salvage
capabilities. ERT acquires, produces and develops mature properties prior to
their decommissioning and as such is one of few companies with the combined
attributes of financial strength, reservoir engineering, operations expertise
and company-owned salvage assets that is acquiring mature properties in the Gulf
of Mexico.

RECENT EVENTS

Excess supplies of crude oil and lower demand internationally drove oil
prices to $11 a barrel by late fall of 1998. At the outset of 1999, the state of
the world's economies and the actions of our customers, who are cutting budgets
and reducing capital expenditures, continues to affect almost all aspects of the
oil and gas industry. While losses from customer inability to pay (bad debt
expenses) have historically been insignificant, the current downturn could also
result in bankruptcy or liquidation of certain of the smaller production
companies that operate in the Gulf. Although CDI believes these pressures may
not be resolved in 1999, it has developed measured responses to these
conditions. For example, CDI has implemented cost reduction and containment
initiatives and expects to continue to do so as conditions dictate. Most of Cal
Dive's employees and management were with the Company when it experienced
cyclical downturns such as those in 1985-6 and 1992. Lessons learned from those
times will be applied. However, it is difficult to forecast the

1

full impact of such a severe cyclical downturn. Some opportunities which CDI
plans to pursue in 1999 are described below.

ERT ACQUISITIONS

In 1998, ERT acquired interests in six blocks involving two fields. Early
in 1999, ERT completed three additional acquisitions (including its largest
acquisition to date) by purchasing interests in seventeen blocks involving seven
separate fields. With these acquisitions, ERT as of March 19, 1999 owned
interests in 35 offshore leases including 32 platforms, 22 caissons, and 184
wells which currently produce about 21 MMCFD and 755 BOPD and has accumulated a
significant backlog of CDI decommissioning work. Given recent oil and gas
company down sizing and layoffs, management believes many of its customers are
reassessing the cost of retaining marginal properties and expects ERT will
benefit from this activity.

SHALLOW WATER FULL-FIELD DEVELOPMENT

CDI believes it has assembled a unique new product/service designed to
bring a new field online efficiently and in periods of as little as seventeen
weeks. Working with proven designs that meet or exceed industry standards, Cal
Dive now stocks or has ready access to the necessary production equipment such
as subsea trees, prefabricated facility modules, well controls, and decks to
assist in the rapid assembly of a new field. Currently under contract to SOCO
Offshore, CDI has completed the staging of a subsea tree and production
equipment within the 12 week target and will mobilize the installation spread
upon completion of drilling operations on the host facility. This equipment,
combined with CDI's years of experience and assets which can complete all phases
of the operation should allow clients to minimize contractor interfaces and
accurately assess costs for the life of their field.

HORIZON ALLIANCE

In the fourth quarter of 1998, CDI entered into an Alliance agreement that
provides access to expanded derrick and heavy lift barge capabilities. Under the
agreement, Horizon exclusively contracts Cal Dive for all dive support vessels
and barge diving services. In return, Cal Dive has agreed to utilize Horizon
pipelay and derrick barges exclusively for large diameter pipelay and salvage
lifts beyond current CDI capabilities. In this regard Cal Dive has guaranteed a
certain level of barge activity which it expects to use in conjunction with its
salvage operations. In the fourth quarter of 1998, Cal Dive vessels and divers
were used for over 180 combined days of work in conjunction with Horizon pipelay
operations and for 20 days on salvage work.

Q4000 MSV

The Q4000, a sixth generation multi-service Deepwater completion and
construction support vessel, is now in the final design stages. Much of 1998 was
spent refining the design of this new build vessel to incorporate more unique
features. A technology sharing alliance with R& B Falcon allowed the Company to
utilize the experiences of operating the UNCLE JOHN and the IOLAIR, two
third-generation semi-submersible vessels. CDI is presently in the process of
evaluating final cost estimates from a select group of shipyards with final
evaluations scheduled for mid-year 1999.

DESCRIPTION OF OPERATIONS

2

THE INDUSTRY AND CDI

The subsea services industry in the Gulf of Mexico originated in the early
1960s to assist natural gas and oil companies with offshore operations. The
industry has grown significantly since the early 1970s as the domestic oil and
gas industry has increasingly relied upon offshore fields for new production.
Subsea services are required throughout the economic life of an offshore field
and include the following services, among others:

o Exploration. Pre-installation survey; rig positioning and installation
assistance; drilling inspection; subsea equipment maintenance; search
and recovery operations.

o Development. Installation of production platforms; installation of
subsea production systems; pipelay support including connecting
pipelines to risers and subsea assemblies; pipeline stabilization,
testing and inspection; cable and umbilical lay and connection.

o Production. Inspection, maintenance and repair of production
structures, risers and pipelines and subsea equipment.

o Decommissioning. Decommissioning and remediation services; plugging and
abandonment services; platform salvage and removal; pipeline
abandonment; site inspections.

Terms defined below are helpful to understanding the services CDI performs in
support of the phases of offshore field development:

4-POINT: Anchors set (two each) from the fore and aft position of the
vessel.

DECOMMISSIONING: The process, supervised by the Minerals Management
Service ("MMS"), of plugging the well, capping and burying the pipelines
serving the field, removing the platform and clearing the site of all
debris.

DIVE SUPPORT VESSEL (DSV): Specially equipped vessel which performs
services and acts as an operational base for divers, ROVs and specialized
equipment.

DYNAMIC POSITIONING (DP): Computer-directed thruster systems, that use
satellite-based positioning combined with other positioning technologies,
to ensure the proper counteraction to wind, current and wave forces
enabling the vessel to maintain its position without the use of anchors.
Two additional DP systems are used to provide the redundancy necessary to
support safe deployment of divers where only a single DP system is
necessary to support ROV equipment

MOONPOOL: An opening in the center of a vessel through which a SAT diving
system or ROV may be deployed, allowing the safest diver or ROV deployment
in adverse weather conditions.

REMOTELY OPERATED VEHICLE (ROV): Robotic vehicles used to complement,
support and increase the efficiency of diving and subsea operations and
for tasks beyond the capability of manned diving operations.

SATURATION (SAT) DIVING: SAT diving, required for work in water depths
greater than 300 feet, involves divers working from special chambers for
extended periods at a pressure equivalent to the depth of the work site.


3

SPOT MARKET: Market unique to the Gulf of Mexico characterized by projects
generally short in duration and of a turnkey nature. These projects
require constant rescheduling and the availability or interchangeability
of multiple vessels.

The Company traces its origins to California Divers Inc., which pioneered
the use of mixed gas diving in the early 1960s when oilfield exploration off the
Santa Barbara coast moved to water depths beyond 250 feet. Cal Dive commenced
operations in the Gulf of Mexico in 1975. The Company's growth strategy has
consisted of three basic elements: (i) identifying the niche markets that are
underserviced or where no service exists, (ii) developing the technical
expertise to provide the service and (iii) acquiring assets or seeking alliances
which fill the market gap. As a result, CDI's revenues have increased by a
compound annual growth rate of 60% from $37.5 million in 1995 to $151.9 million
in 1998. Similarly, net income has increased by a compound annual growth rate of
108% from $2.7 million in 1995 to $24.1 million in 1998. A more detailed
description of the Company's business activities is provided below.

SUBSEA SERVICES

The principal activity of CDI's subsea services involves air and
saturation diving in support of pipelay and related marine construction
activities. Saturation diving is required for diving operations in water depths
beyond 300 feet. CDI believes that it is the largest provider of SAT diving
services and operates the largest fleet of SAT diving vessels permanently
deployed in the Gulf. Cal Dive's diversified fleet includes one DP MSV, three DP
DSVs, two four-point moored saturation DSVs, three other DSVs, two work class
ROVs, a DSV Deepwater service barge and a derrick barge. All of CDI's SAT diving
vessels have moonpool systems, which allow safe diver deployment in adverse
weather conditions. The Company expects delivery in 1999 of a replacement for
its smallest DSV, the CAL DIVER IV. The services provided by these vessels both
overlap and are complementary in a number of market segments, enabling the
Company to deploy its vessels to areas of highest utility and margin potential.
In 1998, demand and rates for these services held fairly firm throughout most of
the year due to shortages of diving personnel. Since CDI dominates the
saturation market where divers receive premium pay, personnel shortages did not
curtail its operations.

Ongoing reductions of experienced personnel at CDI's customers have
continued a trend of transferring more responsibility to contractors and
suppliers. Management believes that a key element of CDI's strategy and success
has been its pioneering role in providing turnkey contracting and its ability to
attract and retain experienced industry personnel. The Company's highly
qualified personnel enable it to compete effectively in the Gulf's unique "spot
market" for offshore construction projects and to manage turnkey projects to
satisfy customer needs and achieve CDI's targeted profitability. Because of its
experience with turnkey contracting and the recognized skill of its personnel,
the Company believes it has proven it can capitalize on the demand for
outsourcing additional responsibility to contractors.

In February 1998, CDI purchased a significant minority stake in Aquatica,
a new shallow water diving company formed by Sonny Freeman, the former Chief
Operating Officer of Ceanic Corporation (formerly American Oilfield Divers)
which was purchased in 1998 by Stolt Comex Seaway, Inc. In 1998, Aquatica's
equity contribution to CDI's pre-tax income was over $2.6 million on a $5.0
million investment. Management believes that its investment in Aquatica permits
the Company to benefit from the skills of proven management in this market while
allowing Cal Dive to continue to focus on its Deepwater strategy. Dependent upon
various preconditions, CDI has agreed to lend an additional $5.0 million to
Aquatica and its shareholders have the right to convert their shares into CDI
shares at a prescribed ratio which, among other things, must be accretive to
CDI's earnings per share.

DEEPWATER TECHNOLOGIES


4

In 1994, CDI began to assemble a fleet of DP vessels which are required to
deliver subsea services in the Deepwater. The Company's Deepwater fleet consists
of one semisubmersible DP MSV (the UNCLE JOHN), three DP DSV's (the WITCH QUEEN,
the BALMORAL SEA, and the MERLIN), one Deepwater service barge (the SEA
SORCERESS), two 4-point moored saturation DSVs (the CAL DIVER I and the CAL
DIVER II) and two work class ROVs. The Company intends to continue to expand the
capabilities of its diversified fleet through the acquisition of additional
vessels and assets. All of CDI's DP vessels (except the MERLIN) can support SAT
diving on the Outer Continental Shelf ("OCS") as compared to most competitors'
DP vessels which can only support ROV work. CDI's mono-hulled DP vessels provide
a flexible work platform to launch ROVs and support subsea construction in
adverse weather conditions. Likewise, the Company's MSV UNCLE JOHN has
demonstrated the ability to perform certain well completion tasks previously
done by more expensive drilling equipment. These vessels, in combination with
the ROVs, allow CDI to control key assets involved in Deepwater subsea
construction and full field development.

CDI formed its Deepwater Technical Services Group in early 1996 to serve
as the focal point for delivering the varied technological disciplines required
for Deepwater projects. Services provided by this Group include geotechnical
investigation, turnkey field development, installation of umbilicals, controls
and flexible pipe, well servicing, decommissioning, subsea wellhead
installations and pipeline repair systems and riser installation. In 1998, the
Company completed or was awarded 15 Deepwater projects requiring DP vessels.
These projects allowed CDI to perform work numerous times at what management
believes to be record depths. Work by Company's alliance partners described
below are also coordinated through this group.

As part of its strategy in the Deepwater Gulf of Mexico, CDI entered into
a number of strategic alliances, including establishment of a joint venture with
Coflexip in April 1997 to pursue EPIC projects in the Gulf and the Caribbean.
Coflexip, headquartered in Paris, France, is a world leader in the design and
manufacture of flexible pipe and umbilicals and is one of the leading subsea
construction contractors. In 1998, Coflexip had sales of $1.34 billion and total
assets of $1.32 billion at year-end. The Coflexip joint venture has not produced
any revenue to date but the Company expects that EPIC projects may develop along
with increased Deepwater activity by 2001. However, Coflexip did make two of
their DP vessels available to the Company which added $8 million to 1998
revenues.

CDI's other alliances, intended to enhance its ability to offer a complete
range of subsea full field development services, are described below:

CDI is also involved in a number of efforts to provide for technical
challenges as the industry moves into the Deepwater. In 1998, the design of
CDI's new build, the Q4000, was refined to include new Deepwater features. CDI
is also involved in seeking solutions to other unique Deepwater issues. In 1998
a number of wells were lost to shallow sand flow, a geological phenomenon unique
to the Deepwater Gulf. CDI is involved with DeepStar, the consortium of 22 oil
companies having significant interest in the Deepwater Gulf in designing a
hammer to drive a 36" caisson 2,000 feet into the ocean floor in order to
provide a drilling conduit through the aquifer. A second major issue is that of
hydrates, the waxy substance which impedes pipeline flow as the high paraffin
content of the oil interacts with the extreme cold of the Deepwater. This
situation presently limits offsets and step out wells as flowline insulation
costs escalate to non-economic levels. CDI and alliance partner Ambar are
developing an extended reach method of cleaning hydrates from the pipeline. In
each case CDI's goal is to develop new Deepwater products which can be deployed
from our fleet of DP vessels.

ABANDONMENT SOLUTIONS

The Company has established a leading position in the decommissioning of
facilities in the shallow water Gulf of Mexico. According to OFFSHORE MAGAZINE,
CDI performed 24% of all structure removal projects in the Gulf from January 1,
1996 through June 30, 1998. The Company expects the demand for decommissioning
services to increase due to the significant number of platforms that must be
removed in accordance with government regulations. Over 75% of the 4,200
platforms in the Gulf of Mexico are over ten years old and there are
approximately 20,000 wells that must ultimately be plugged and abandoned. Since
1989, Cal Dive


6

has undertaken a wide variety of decommissioning assignments, most on a turnkey
basis.

When the structure to be removed exceeds the capacity of CDI's equipment,
the Company can utilize its 1998 alliance with Horizon. Horizon operates three
derrick barges, the PACIFIC HORIZON, ATLANTIC HORIZON and PHOENIX HORIZON, that
have lift capacities ranging up to 800 tons. As a result, CDI should no longer
have to subcontract those projects where the lift exceeds the 200-ton capacity
of the CAL DIVE BARGE-I.

CDI formed ERT in 1992 to exploit a market opportunity to provide a more
efficient solution to the abandonment of offshore properties, to expand Cal
Dive's off season salvage and decommissioning activity and to support full field
development projects. CDI has assembled and recently expanded its team of
personnel experienced in geology, geophysics, reservoir, drilling and production
engineering, facilities management and lease operations to allow ERT to maximize
production at these properties until they are decommissioned. Mature properties
are generally those properties where decommissioning costs are significant
relative to the value of remaining natural gas and oil reserves. CDI seeks to
acquire properties that it can operate to enhance remaining production, control
operating expenses and manage the cost and timing of the decommissioning.
Management believes that CDI is one of the few companies which combines
financial strength, reservoir engineering, operations expertise and the
availability of company-owned salvage assets that is acquiring mature properties
in the Gulf of Mexico. These attributes result in significant strategic and cost
advantages. Since acquiring its initial property in late 1992, the Company has
increased estimated proved reserves to approximately 30.4 Bcfe of natural gas
and oil at March 19, 1999.

CUSTOMERS

The Company's customers include major and independent natural gas and oil
producers, pipeline transmission companies and offshore engineering and
construction firms. The level of construction services required by any
particular customer depends on the size of that customer's capital expenditure
budget devoted to construction plans in a particular year. Consequently,
customers that account for a significant portion of contract revenues in one
fiscal year may represent an immaterial portion of contract revenues in
subsequent fiscal years. The Company estimates that in 1998 it provided subsea
services to approximately 100 customers. Chevron USA, Inc. accounted for 11% of
consolidated revenues in 1998. J. Ray McDermott, S.A. accounted for 19% and 24%
of consolidated revenues in the years 1997 and 1996, respectively. In addition,
Shell Oil Co. accounted for 11% of consolidated revenues in 1997. The Company's
projects are typically of short duration and are generally awarded shortly
before mobilization. Accordingly, backlog is not a meaningful indicator of
future activities.

COMPETITION

The subsea services industry is highly competitive. Competition has
historically been based on factors such as the location and type of equipment
available, the ability to deploy such equipment, the safety and quality of
service in recent years and price. While price is a factor, the ability to
acquire specialized vessels, to attract and retain skilled personnel, and to
demonstrate a good safety record are important competitive factors. CDI's
competitors in the shallower waters of the Gulf include Stolt Comex Seaway, Inc.
(formerly Ceanic Corporation), Torch, Inc., Global Industries Ltd. and
Oceaneering International, Inc. as well as a number of smaller companies, some
of which only operate a single vessel, that often compete solely on price. For
Deepwater projects, Cal Dive's principal U.S. based competitors include
Oceaneering International, Inc., Global Industries, Ltd. and Stolt Comex Seaway,
Ltd. Other large foreign based subsea contractors, including, DSND, ASA and
Rockwater, Ltd., may perform services in the Gulf. Of those competitors,
Oceaneering has recently introduced the OCEAN INTERVENTION I and has announced
plans to have a second vessel (OCEAN INTERVENTION II) in the marketplace late in
1999. SCS now has the CONDOR in the Gulf with the PUMA a possible arrival later


7

in the year. CDI also encounters significant competition for the acquisition of
producing natural gas and oil properties. The Company's ability to acquire
additional properties also depends upon its ability to evaluate and select
suitable properties and to consummate transactions in a highly competitive
environment. Many of the Company's competitors are well-established companies
with substantially larger operating staffs and greater capital resources than
CDI which, in many instances, have been engaged in the energy business for a
much longer time than CDI.

TRAINING, SAFETY AND QUALITY ASSURANCE

CDI maintains a stringent safety and quality assurance program. In 1994,
the Company devised and instituted a comprehensive revision to its safety
program which emphasizes team building by assembling a core group of personnel
specifically for each vessel to promote offshore efficiency and safety.
Assembling core groups of personnel specifically assigned to each vessel has
also reduced recorded incidents. As a result, management believes that CDI's
safety programs are among the best in the industry.

GOVERNMENT REGULATION

Many aspects of the offshore marine construction industry are subject to
extensive governmental regulation. The Company is subject to the jurisdiction of
the United States Coast Guard ("USCG"), the Environmental Protection Agency,
Minerals Management Service ("MMS") and the U.S. Customs Service ("USCS") as
well as private industry organizations such as the American Bureau of Shipping
("ABS").

CDI supports and voluntarily complies with the Association of American
Diving Contractor Standards. The USCG sets safety standards and is authorized to
investigate vessel and diving accidents and recommend improved safety standards,
and the USCS is authorized to inspect vessels at will. CDI 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 or can obtain all permits, licenses and certificates
necessary for the conduct of its business.

In addition, CDI depends on the demand for its services from the oil and
gas industry and, therefore, the Company's business is affected by laws and
regulations, as well as changing taxes and policies relating to the oil and gas
industry generally. In particular, the development and operation of natural gas
and oil properties located on the OCS of the United States is regulated
primarily by the MMS.

The MMS requires lessees of OCS properties to post bonds in connection
with the plugging and abandonment of wells located offshore and the removal of
all production facilities. Operators in the OCS waters of the Gulf of Mexico are
currently required to post an area wide bond of $3.0 million or $500,000 per
producing lease. The Company currently has bonded its offshore leases as
required by the MMS. Under certain circumstances, the MMS has the authority to
suspend or terminate operations on federal leases. Any such suspensions or
terminations of the Company's operations could have a material adverse effect on
the Company's financial condition and results of operations.
The Company acquires production rights to offshore mature oil and gas
properties under federal oil and gas leases, which the MMS administers. These
leases contain relatively standardized terms and require compliance with
detailed MMS regulations and orders pursuant to the Outer Continental Shelf
Lands Act ("OCSLA") (which are subject to change by the MMS). The MMS has
promulgated regulations requiring offshore production facilities located on the
OCS to meet stringent engineering and construction specifications. These latter
regulations were withdrawn pending further discussions among interested federal
agencies. The MMS also has issued regulations restricting the flaring or venting
of natural gas and prohibiting the burning of liquid hydrocarbons without prior
authorization. Similarly, the MMS has promulgated other regulations


8

governing the plugging and abandonment of wells located offshore and the removal
of all production facilities. Finally, under certain circumstances, the MMS may
require any operations on federal leases to be suspended or terminated, and the
MMS has recently proposed, but not yet enacted, regulations that would allow it
to expel unsafe operators from existing OCS platforms and bar them from
obtaining future leases. Any such suspension or termination or ban could
materially and adversely affect the Company's financial condition and
operations.

The MMS has also issued a notice of proposed rulemaking in which it
proposes to amend its regulations governing the calculation of royalties and the
valuation of crude oil produced from federal leases. The proposed rule would
modify the valuation procedures for both arm's length and non-arm's length crude
oil transactions to decrease reliance on oil posted prices and assign a value to
crude oil that better reflects market value, establish a new MMS form for
collecting value differential data, and amend the valuation procedure for the
sale of federal royalty oil. The Company cannot predict at this stage of the
rulemaking proceeding how it might be affected by this amendment to the MMS'
regulations. In addition, the MMS recently issued a final rule amending its
regulations regarding costs for gas transportation which are deductible for
royalty valuation purposes when gas is sold offlease. Among other matters, for
purposes of computing royalty owed, the rule disallows as deductions certain
costs, such as aggregator/marketer fees and transportation imbalance charges and
associated penalties.

Historically, the transportation and sale for resale of natural gas in
interstate commerce has been regulated pursuant to the Natural Gas Act of 1938,
the Natural Gas Policy Act of 1978 (the "NGPA"), and the regulations promulgated
thereunder by the Federal Energy Regulatory Commission (the "FERC"). In the
past, the federal government has regulated the prices at which gas and oil could
be sold. While sales by producers of natural gas, and all sales of crude oil,
condensate, and natural gas liquids can currently be made at uncontrolled market
prices, Congress could reenact price controls in the future. Deregulation of
wellhead sales in the natural gas industry began with the enactment of the NGPA.
In 1989, the Natural Gas Wellhead Decontrol Act was enacted. This act amended
the NGPA to remove both price and non-price controls from natural gas sold in
"first sales" no later than January 1, 1993.

Sales of natural gas are affected by the availability, terms and cost of
transportation. The price and terms for access to pipeline transportation remain
subject to extensive federal and state regulation. Several major regulatory
changes have been implemented by Congress and the FERC from 1985 to the present
that affect the economics of natural gas production, transportation and sales.
In addition, the FERC continues to promulgate revisions to various aspects of
the rules and regulations affecting those segments of the natural gas industry,
most notably interstate natural gas transmission companies that remain subject
to the FERC's jurisdiction. These initiatives may also affect the intrastate
transportation of gas under certain circumstances. The stated purpose of many of
these regulatory changes is to promote competition among the various sectors of
the natural gas industry. The ultimate impact of the complex rules and
regulations issued by the FERC since 1985 cannot be predicted. In addition, many
aspects of these regulatory developments have not become final but are still
pending judicial and FERC final decisions.

The Company cannot predict what further action the FERC will take on these
matters, however, the Company does not believe that it will be affected by any
action taken materially differently than other companies with which it competes.

Additional proposals and proceedings before various federal and state
regulatory agencies and the courts could affect the oil and gas industry. The
Company cannot predict when or whether any such proposals may become effective.
In the past, the natural gas industry has been heavily regulated. There is no
assurance that the regulatory approach currently pursued by the FERC will
continue indefinitely. Notwithstanding the foregoing, the Company does not
anticipate that compliance with existing federal, state and local laws, rules,


9

and regulations will have a material effect upon the capital expenditures,
earnings, or competitive position of the Company.

The Company has assessed what computer software will require modification
or replacement so that its computer systems will properly utilize dates beyond
December 31, 1999. The Company has purchased, and has implemented, a new project
management accounting system which is Year 2000 compliant. This system, which
fully integrates all of its modules, provides project managers and accounting
personnel with up-to-date information enabling them to better control jobs in
addition to providing benefits in inventory control and planned vessel
maintenance. CDI's vessel computer DP systems are partially dependent on
government satellites and the government has not yet confirmed that they have
solved Year 2000 data problems. If necessary, the vessels could operate for
sometime safely on redundant systems other than satellite information.
Accordingly, the Company believes that the Year 2000 issue will be resolved in a
timely manner and presently does not believe that the cost to become Year 2000
compliant will have a material adverse effect on the Company's consolidated
financial statements. The foregoing statements are intended to be and are hereby
designated "Year 2000 Readiness Disclosure" within the meaning of the Year 2000
Information Readiness and Disclosure Act.

ENVIRONMENTAL REGULATIONS

The Company's operations are subject to a variety of federal, state and
local laws and regulations governing the discharge of materials into the
environment or otherwise relating to environmental protection. Numerous
governmental departments issue rules and regulations to implement and enforce
such laws that are often complex and costly to comply with, and that carry
substantial administrative, civil and possibly criminal penalties for failure to
comply. Aside from possible liability for damages and costs associated with
releases of hazardous materials including oil into the environment, such laws
and regulations may impose liability on the Company for the conduct of or
conditions caused by others, or by acts of the Company that were in compliance
with all applicable laws at the time such acts were performed.

The Oil Pollution Act of 1990, as amended ("OPA"), imposes a variety of
requirements on "responsible parties" related to the prevention of oil spills
and liability for damages resulting from such spills in waters of the United
States. A "responsible party" includes the owner or operator of an onshore
facility, vessel or pipeline, or the lessee or permittee of the area in which an
offshore facility is located. OPA imposes liability on each responsible party
for oil spill removal costs and for other public and private damages from oil
spills. Failure to comply with OPA may result in the assessment of civil and
criminal penalties. OPA establishes liability limits of up to $350.0 million for
onshore facilities, all removal costs plus up to $75.0 million for offshore
facilities, and the greater of $500,000 or $600 per gross ton for vessels other
than tank vessels. The liability limits are not applicable, however, if the
spill is caused by gross negligence or willful misconduct, if the spill resulted
from violation of a federal safety, construction, or operating regulation, or if
a party fails to report a spill or fails to cooperate fully in the cleanup. Few
defenses exist to the liability imposed under OPA. Management of the Company is
currently unaware of any oil spills for which the Company has been designated as
a responsible party under OPA that will have a material adverse impact on the
Company or its operations.

OPA also imposes ongoing requirements on a responsible party including
preparation of an oil spill contingency plan and proof of financial
responsibility to cover a majority of the costs in a potential spill. The
Company believes it has appropriate spill contingency plans in place. Vessels
subject to OPA other than tank vessels are subject to financial responsibility
limits of the greater of $500,000 or $600 per gross ton, while offshore
facilities are subject to financial responsibility limits of not less than $35.0
million, with that limit potentially increasing up to $150.0 million if a formal
risk assessment indicates that a greater amount is required. The MMS has
promulgated regulations implementing these financial responsibility requirements
for


10

covered offshore facilities. Under the MMS regulations, the amount of financial
responsibility required for an offshore facility is increased above the minimum
amounts of the "worst case" oil spill volume calculated for the facility exceeds
certain limits established in the regulations. The Company believes that it
currently has established adequate proof of financial responsibility for its
vessels and onshore and offshore facilities and that it satisfies the MMS
requirements for financial responsibility under OPA and the proposed
regulations.


OPA also requires owners and operators of vessels over 300 gross tons to
provide the USCG with evidence of financial responsibility to cover the cost of
cleaning up oil spills from such vessels. The Company currently owns and
operates five vessels over 300 gross tons. Satisfactory evidence of financial
responsibility has been provided to the USCG for all of the Company's vessels.

The Clean Water Act imposes strict controls on the discharge of pollutants
into the navigable waters of the U.S., and imposes potential liability for the
costs of remediating releases of petroleum and other substances. The Clean Water
Act provides for civil, criminal and administrative penalties for any
unauthorized discharge of oil and other hazardous substances and imposes
substantial potential liability for the costs of removal, remediation and
damages. Many states have laws which are analogous to the Clean Water Act and
also require remediation of releases of petroleum and other hazardous substances
in state waters. The Company's vessels routinely transport diesel fuel to
offshore rigs and platforms, and also carry diesel fuel for their own use. The
Company's supply boats transport bulk chemical materials used in drilling
activities, and also transport liquid mud which contains oil and oil
by-products. Offshore facilities and vessels operated by the Company have
facility and vessel response plans to deal with potential spills of oil or its
derivatives.

OCSLA provides the federal government with broad discretion in regulating
the release of offshore resources of natural gas and oil production as well as
regulating safety and environmental protection applicable to lessees and
permittees operating in the OCS. Specific design and operational standards may
apply to OCS vessels, rigs, platforms, vehicles and structures. Violations of
lease conditions or regulations issued pursuant to OCSLA can result in
substantial civil and criminal penalties, as well as potential court injunctions
curtailing operations and cancellation of leases. 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 action could have a material
adverse effect on the Company's financial condition and the results of
operations. As of this date, the Company believes it is not the subject of any
civil or criminal enforcement actions under OCSLA.

The Comprehensive Environmental Response, Compensation, and Liability Act
("CERCLA") contains provisions dealing with remediation of releases of hazardous
substances into the environment and imposes liability without regard to fault or
the legality of the original conduct, on certain classes of persons including
owners and operators of contaminated sites where the release occurred and those
companies who transport, dispose of or who arrange for disposal of hazardous
substances released at the sites. Under CERCLA, such persons may be subject to
joint and several liability for the costs of cleaning up the hazardous
substances that have been released into the environment, for damages to natural
resources and for the costs of certain health studies, and it is not uncommon
for third parties to file claims for personal injury and property damage
allegedly caused by the release of hazardous substances. Although the Company
handles hazardous substances in the ordinary course of business, the Company is
not aware of any hazardous substance contamination for which it may be liable.

Management believes the Company is in compliance in all material respects
with all applicable environmental laws and regulations to which it is subject.
The Company does not anticipate that compliance with existing environmental laws
and regulations will have a material effect upon the capital expenditures,
earnings or competitive position of the Company. However, changes in the
environmental laws and regulations,


11

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.

EMPLOYEES

CDI relies on the high quality of its workforce and has successfully
hired, trained, and retained skilled managers and divers. As of December 31,
1998 the Company had 478 employees, 127 of which were salaried. As of that
date the Company also utilized approximately 105 non-US citizens to crew its
foreign flag vessels under a crewing contract with C-MAR Services (UK), Ltd. of
Aberdeen, Scotland. None of the Company's employees belong to a union or are
employed pursuant to any collective bargaining agreement or any similar
arrangement. Management believes that the Company's relationship with its
employees and foreign crew members is good.

Of the Company's employees, approximately 225 persons own shares of Common
Stock and 43 other employees hold options to acquire Common Stock under the
Company's 1995 Long Term Incentive Plan, as amended.

FACTORS INFLUENCING FUTURE RESULTS AND ACCURACY OF
FORWARD LOOKING INFORMATION

Shareholders should carefully consider the following risk factors in
addition to the other information contained in this Annual Report. This Annual
Report on Form 10-K includes certain statements that may be deemed
"forward-looking statements" within the meaning of Section 27A of the Securities
Act and Section 21E of the Exchange Act. All statements other than statements of
historical facts, included in this Annual Report 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 CDI or projections involving anticipated revenues, earnings, or
other aspects of operating results are forward-looking statements. The words
"expect," "believe," "anticipate," "project," "estimate," and similar
expressions are intended to identify 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 tend to influence the
accuracy of the statements and the projections upon which the statements are
based, including but not limited to those discussed below. As noted elsewhere,
all phases of CDI's operations are subject to a number of uncertainties, risks
and other influences, many of which are outside the control of CDI, and any one
or a combination of which could materially affect the results of CDI's
operations and the accuracy of forward-looking statements made by CDI. The
following discussion outlines certain factors that could affect CDI's
consolidated results of operations for 1999 and beyond and cause them to differ
materially from those that may be set forth in forward-looking statements made
by or on behalf of the Company.

LOW OIL AND NATURAL GAS PRICES AND CYCLICALITY OF THE OIL AND GAS INDUSTRY

The Company's business is substantially dependent upon the condition of
the oil and gas industry and, in particular, the willingness of oil and gas
companies to make capital expenditures on exploration, drilling and production
operations offshore. The level of capital expenditures is generally dependent on
the prevailing view of future oil and gas prices, which are influenced by
numerous factors affecting the supply and demand for oil and gas, including
worldwide economic activity, interest rates and the cost of capital,
environmental regulation, tax policies, coordination by the Organization of
Petroleum Exporting Countries ("OPEC"), the cost of exploring for and producing
oil and gas, the sale and expiration dates of offshore leases in the United
States and overseas, the discovery rate of new oil and gas reserves in offshore
areas and technological advances. Oil


12

and gas prices and the level of offshore drilling and production activity have
recently dropped significantly. There can be no assurance that activity levels
will increase any time soon. A sustained period of low hydrocarbon prices would
likely have a material adverse effect on the Company's financial position and
results of operations.

VESSEL OPERATING RISKS AND LIMITATION OF INSURANCE COVERAGE

Marine construction involves a high degree of operational risk. Hazards,
such as vessels sinking, grounding, colliding and sustaining damage from severe
weather conditions are inherent in marine operations. 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.
Damage arising from such an occurrence may result in lawsuits asserting large
claims. CDI maintains such insurance protection as it deems prudent, including
Jones Act employee coverage (the maritime equivalent of workers compensation)
and hull insurance on its vessels. There can be no assurance that any such
insurance will be sufficient or effective under all circumstances or against all
hazards to which CDI may be subject. A successful claim for which CDI is not
fully insured could have a material adverse effect on the Company. Moreover, no
assurance can be given that CDI will be able to maintain adequate insurance in
the future at rates that it considers reasonable. As construction activity moves
into deeper water in the Gulf of Mexico, construction projects tend to be larger
and more complex than shallow water projects. As a result, the Company's
revenues and profits are increasingly dependent on its larger vessels. While the
Company currently insures its vessels against property loss due to a
catastrophic marine disaster, mechanical failure or collision, the loss of any
of the Company's large vessels as a result of such event could result in a
substantial loss of revenues, increased costs and other liabilities and could
have a material adverse effect on the Company's operating performance.

SEASONALITY AND ADVERSE WEATHER RISKS

Marine operations conducted in the Gulf of Mexico are seasonal and depend,
in part, on weather conditions. Historically, CDI has enjoyed its highest vessel
utilization rates during the summer and fall of the year when weather conditions
are favorable for offshore exploration, development and construction activities
and has experienced its lowest utilization rates in the first quarter. During
certain periods of the year, CDI typically bears the risk of delays caused by
adverse weather conditions. Accordingly, the results of any one quarter are not
necessarily indicative of annual results or continuing trends.

CONTRACT BIDDING AND ALLIANCE RISKS

A majority of CDI's projects are currently performed on a qualified
turnkey basis. The revenue, cost and gross profit realized on a contract can
vary from the estimated amount because of changes in offshore job conditions,
variations in labor and equipment productivity from the original estimates and
performance of others such as alliance partners. These variations and risks
inherent in the marine construction industry may result in CDI experiencing
reduced profitability or losses on projects. Although CDI has entered into a
number of strategic alliances, there can be no assurance that CDI will be able
to enter into such alliances in the future, that these alliances will be
successful or that contracts resulting from these alliances will not result in
unforeseen operational difficulties.

UNCERTAINTY OF ESTIMATES OF NATURAL GAS AND OIL RESERVES

This Annual Report contains an estimate of the Company's proved natural
gas and oil reserves and the estimated future net cash flows therefrom based
upon a report prepared as of December 31, 1998 by Miller & Lents, which report
relies upon various assumptions, including assumptions required by the
Commission as


13

to natural gas and oil prices, drilling and operating expenses, capital
expenditures, taxes and availability of funds. The process of estimating natural
gas and oil reserves is complex, requiring significant decisions and assumptions
in the evaluation of available geological, geophysical, engineering and economic
data for each reservoir. As a result, such estimates are inherently imprecise.
Actual future production, cash flows, development expenditures, operating
expenses and quantities of recoverable natural gas and oil reserves may vary
substantially from those estimated in the report. Any significant variance in
these assumptions could materially affect the estimated quantity and value of
the Company's proved reserves.

NATURAL GAS AND OIL OPERATING RISKS

The Company's natural gas and oil operations are subject to the usual
risks incident to the operation of natural gas and oil wells, including, but not
limited to, uncontrollable flows of oil, natural gas, brine or well fluids into
the environment, blowouts, cratering, mechanical difficulties, fires,
explosions, pollution and other risks, any of which could result in substantial
losses to the Company. In accordance with industry practice, CDI maintains
insurance against some, but not all, of the risks described above.

COMPETITION

The business in which the Company operates is highly competitive. Several
of the Company's competitors are companies that are substantially larger and
have greater financial and other resources than the Company. If other companies
relocate or acquire vessels for operations in the Gulf of Mexico, levels of
competition may increase and the Company's business could be adversely affected.

CUSTOMER CONCENTRATION

CDI's customers consist primarily of major and independent natural gas and
oil producers, pipeline transmission companies and offshore engineering and
construction companies. During 1997, the Company derived approximately 19% of
its consolidated revenues from one customer and 11% from another. CDI derived
11% of its consolidated revenue in 1998 from another customer. While CDI
currently has a good relationship with its customers, the loss of any one of its
largest customers, or a sustained decrease in demand, could result in a
substantial loss of revenues and could have a material adverse effect on CDI's
operating performance. While losses from customer inability to pay (bad debt
expenses) have historically been insignificant, the current downturn in
commodity prices could result in bankruptcy or liquidation of certain of the
smaller production companies that operate in the Gulf.

DEPENDENCE ON KEY PERSONNEL AND RETENTION OF EMPLOYEES

CDI's success depends on the continued active participation of key
management personnel. The loss of key people could adversely affect CDI's
operations. The Company has two-year employment and non-compete agreements with
twelve of its senior officers. CDI believes that its success and continued
growth is also dependent upon its ability to employ and retain skilled
personnel. While the Company believes that its wage rates are competitive and
that its relationship with its workforce is good, a significant increase in the
wages paid by other employers could result in a reduction in the Company's
workforce, increases in the wage rates paid by the Company, or both. If either
of these events occur for any significant period of time, the Company's
profitability could be diminished and the growth potential of the Company could
be impaired.

REGULATORY AND ENVIRONMENTAL MATTERS

CDI's subsea construction, inspection, maintenance and decommissioning
operations and its natural gas


14

and oil production from offshore properties (including decommissioning of such
properties) are subject to and affected by various types of government
regulation, including numerous federal, state and local environmental protection
laws and regulations. These laws and regulations are becoming increasingly
complex, stringent and expensive and there can be no assurance that continued
compliance with existing or future laws or regulations will not adversely affect
the operations of CDI. Significant fines and penalties may be imposed for
non-compliance.

ANTI-TAKEOVER CONSIDERATIONS

The Board of Directors of CDI has the authority, without any action by the
shareholders, to fix the rights and preferences on up to 5,000,000 shares of
undesignated preferred stock, including dividend, liquidation and voting rights.
In addition, CDI's Articles of Incorporation divide the Company's Board of
Directors into three classes. Except for a transaction involving Coflexip (which
is specifically excluded), CDI also is subject to certain anti-takeover
provisions of the Minnesota Business Corporations Act ("MBCA"). In addition, CDI
is a party to a Shareholders Agreement that provides Coflexip with a right of
first refusal in connection with certain acquisition proposals for CDI and has
employment contracts with twelve (12) of its officers which require cash
payments in the event of a "change of control". Any or all of the provisions or
factors described above may have the effect of discouraging a takeover proposal
or tender offer not approved by management and the Board of Directors of CDI,
and could result in shareholders who may wish to participate in such a proposal
or tender offer receiving less for their shares than otherwise might be
available in the event of a takeover attempt.

ITEM 2. PROPERTIES

MARINE VESSELS AND EQUIPMENT

GENERAL

The Company owns a fleet of 11 vessels and two ROVs. The size of the
Company's fleet and its capabilities have increased in recent years with the
addition of the WITCH QUEEN, BALMORAL SEA, UNCLE JOHN, SEA SORCERESS and MERLIN.

Management believes that the Gulf of Mexico market increasingly will
require specially designed or equipped vessels to deliver the necessary subsea
construction services, especially in the Deepwater. Six of CDI's vessels have
the permanent capability to provide SAT diving services. Four of CDI's vessels
have DP capabilities specifically designed to respond to the Deepwater market.

NEW VESSELS

In 1998, the design of CDI's new MSV, the Q4000 was refined to include
more features. It is a sixth generation, multi-service vessel which is a newer
version of the MSV UNCLE JOHN'S column stabilized, semisubmersible design and is
unique due to the absence of lower hull cross bracing which decreases vessel
weight and increases operating efficiency. Variable deck load of 4,000 tons and
a large deck area would make the vessel particularly well suited for large
offshore construction projects in Deepwater. High transit speed would allow it
to move rapidly from one location to another while operability (thruster power
and motion characteristics) would provide for well intervention in an extremely
cost effective manner. Management expects that there would be a derrick similar
to that installed on the MSV UNCLE JOHN for well completion and well servicing
projects. Final evaluation is scheduled for mid-1999 but there is no assurance
that the Q4000 will be constructed.

The DSV SEA SORCERESS began a contract in the third quarter of 1998 to
assist a large new field development project offshore of Newfoundland, Canada.
This contract was cancelled in early 1999. Due to the cancellation, it is
expected this vessel may remain idle for some time. The vessel was purchased as
a candidate to convert to DP and target Deepwater heavy construction projects.
Long lead time components such as the thrusters have been purchased and the
engineering completed so the Company believes the conversion can be completed in
a six to nine month time frame. However, this $30 to $35 million capital
expenditure will not be undertaken until commodity prices and market conditions
improve.

In early 1998, CDI contracted to have a replacement vessel built for its
utility boat CAL DIVER IV as part of its ongoing program to upgrade the quality
of its fleet. The original CAL DIVER IV was sold to Aquatica, Inc. in January
1999. The new vessel is 120 feet long, 32 feet wide, has 1,440 feet of clear
deck space, a 60 ton deck load capacity and galley accommodations for 24 people.
It will be capable of 10 knots cruising speed and is expected to be delivered in
mid-1999.

(1) This vessel was operated by the Company under charters from September 1994
to February 1995 and from April 1996 to August 8, 1996, at which time it
was acquired by the Company.

(2) Delivery of this vessel is expected in mid-1999.

(3) Under government regulations and CDI's insurance policies, the Company is
required to maintain its vessels in accordance with standards of
seaworthiness and safety set by government regulations and classification
organizations. CDI maintains its fleet to the standards for seaworthiness,
safety and health set by both the American Bureau of Shipping ("ABS"), Det
Norske Veritas ("DNV") and the United States Coast Guard ("USCG"). The ABS
is one of several classification societies used by ship owners to certify
that their vessels meet certain structural, mechanical and safety equipment
standards, including Lloyd's Register, Bureau Veritas and DNV among others.

CDI incurs routine drydock inspection, maintenance and repair costs under
USCG Regulations and to maintain ABS or DNV classification for its vessels. In
addition to complying with these requirements, the Company has its own vessel
maintenance program which management believes permits Cal Dive to continue to
provide its customers with well maintained, reliable vessels. In the normal
course of its operations, the Company also charters other vessels on a
short-term basis, such as tugboats, cargo barges, utility boats and dive support
vessels. All of the Company's vessels are subject to ship mortgages.

SUMMARY OF NATURAL GAS AND OIL RESERVE DATA

(1) Seventeen (17) blocks purchased in 1999 described below are not included in
the above December 31, 1998 summary. As a result of this purchase, ERT's
Estimated Proven Reserves have increased approximately 32% to 29,300 MMCF
of natural gas and 152 MBbls of oil and the standardized measure of
discounted future net cash flow has increased to $22,779.

(2) The standardized measure of discounted future net cash flows attributable
to the Company's reserves was prepared using constant prices as of the
calculation date, discounted at 10% per annum.

As of March 19, 1999, the Company owned an interest in 145 gross (125 net)
natural gas wells and 45 gross (25 net) oil wells located in federal offshore
waters in the Gulf of Mexico.

ITEM 3. LEGAL PROCEEDINGS.

CDI's operations are subject to the inherent risks of offshore marine
activity, including accidents resulting in personal injury and the loss of life
or property, environmental mishaps, mechanical failures and collisions. The
Company insures against these risks at levels consistent with industry
standards. CDI believes its insurance is adequate to protect it against, among
other things, the cost of replacing the total or constructive total loss of its
vessels. The Company also carries workers' compensation, maritime employer's
liability, general liability and other insurance customary in its business. All
insurance is carried at levels of coverage and deductibles that CDI considers
financially prudent. CDI's services are provided in hazardous environments where
accidents involving catastrophic damage or loss of life could result, and
litigation arising from such an event may result in the Company being named a
defendant in lawsuits asserting large claims. To date, the Company has been
involved in no such catastrophic lawsuit. Although there can be no assurance
that the amount of insurance carried by CDI is sufficient to protect it fully in
all events, management believes that its insurance protection is adequate for
the Company's business operations. A successful liability claim for which CDI is
underinsured or uninsured could have a material adverse effect on the Company.

CDI is involved in various legal proceedings primarily involving claims
for personal injury under the General Maritime Laws of the United States and the
Jones Act as a result of alleged negligence. In addition, the Company from time
to time incurs other claims, such as contract disputes, in the normal course of
business. The Company believes that the outcome of all such proceedings, even if
determined adversely, would not have a material adverse effect on its business
or financial condition.

OWEN KRATZ has served as the Company's Chairman since May of 1998, Chief
Executive Officer since April 1997, President since 1993 and Chief Operating
Officer and director since 1990. He joined the Company in 1984 and has held
various offshore positions, including SAT diving supervisor, and management
responsibility for client relations, marketing and estimating. From 1982 to
1983, Mr. Kratz was the owner of an independent marine construction company

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

OVERVIEW

Natural gas and oil prices, the offshore mobile rig count and Gulf of
Mexico lease activity are three of the primary indicators management uses to
predict the level of the Company's business. CDI's construction services
generally follow successful drilling activities by six to eighteen months on the
Continental Shelf and twelve to twenty-four in the Deepwater arena. The level of
drilling activity is related to both short and long-term trends in natural gas
and oil prices. Recently commodity prices have declined significantly resulting
in the utilization of offshore mobile rigs dropping to approximately 70% in
contrast to almost full utilization in 1997 and the first half of 1998. Should
this period of low oil and gas prices persist, demand for the Company's services
could be negatively impacted in 1999.

Product prices impact the Company's natural gas and oil operations in
several respects. The Company seeks to acquire producing natural gas and oil
properties that are generally in the later stages of their economic life. These
properties typically have few, if any, unexplored drilling locations, so the
potential abandonment liability is a significant consideration with respect to
the offshore properties which the Company has purchased to date. Although higher
natural gas prices tend to reduce the number of mature properties available for
sale, these higher prices contributed to improved operating results for the
Company in 1996 and 1997. In contrast, lower natural gas prices, as experienced
in 1998, contributed to lower operating results for ERT in 1998 and has
increased the number of mature properties available for sale such that the
Company has completed three transactions involving interests in 17 offshore
blocks early in 1999. Salvage operations consist of platform decommissioning,
removal and abandonment and P&A services performed by the Company's salvage
assets, i.e., a stiff-leg derrick barge and well servicing equipment. In
addition, salvage related support, such as debris removal and preparation of
platform legs for removal, is often provided by the Company's surface diving
vessels. In 1989, management targeted platform removal and salvage operations as
a regulatory driven activity which offers a partial hedge against fluctuations
in the commodity price of natural gas. In particular, MMS regulations require
removal of platforms within twelve months after lease expiration and also
require remediation of the seabed at the well site to its original state. The
Company contracts and manages, on a turnkey basis, all aspects of the
decommissioning and abandonment of fields of all sizes using third party heavy
lift derrick barges if necessary. The Company has entered into an alliance with
Horizon Offshore gaining


23

access to expanded derrick barge and pipelay capacity. In this regard Cal Dive
has guaranteed a certain level of barge activity which it expects to use in
conjunction with CDI salvage operations.

The following table sets forth for the periods presented (i) average U.S.
natural gas prices, (ii) the Company's natural gas production, (iii) the average
number of offshore rigs under contract in the Gulf of Mexico, (iv) the number of
platforms installed and removed in the Gulf of Mexico and (v) the vessel
utilization rates for each of the major categories of the Company's fleet.

(4) Average vessel utilization rate is calculated by dividing the total
number of days the vessels in this category generated revenues by the
total number of days in each quarter.

Vessel utilization is historically lower during the first quarter due to
winter weather conditions in the Gulf of Mexico. Accordingly, the Company plans
its drydock inspections and other routine and preventive maintenance programs
during this period. During the first quarter, a substantial number of the
Company's customers finalize capital budgets and solicit bids for construction
projects. The bid and award process during the first two quarters leads to the
commencement of construction activities during the second and third quarters. As
a result, the Company has historically generated more than 50% (up to 65%) of
its consolidated revenues in the last six months of the year. The Company's
operations can also be severely impacted by weather during the fourth quarter.
The Company's salvage barge, which has a shallow draft, is particularly
sensitive to adverse weather conditions, and its utilization rate will be lower
during such periods. To minimize the impact of weather conditions on the
Company's operations and financial condition, CDI began operating DP vessels and
expanded into the acquisition of mature offshore properties. The unique station-
keeping ability offered by dynamic positioning enables these vessels to operate
throughout the winter months and in rough seas. Operation of natural gas and oil
properties tends to offset the impact of weather since the first and fourth
quarters are typically periods of high demand for natural gas and of strong
natural gas prices. Due to this seasonality, full year results are not likely to
be a direct multiple of any particular quarter or combination of quarters.

RESULTS OF OPERATIONS

COMPARISON OF YEAR ENDED DECEMBER 31, 1998 TO YEAR ENDED DECEMBER 31, 1997

REVENUES. Consolidated revenues of $151.9 million in 1998 were 39% more
than the $109.4 million earned during 1997 with the Subsea operations
contributing all of the increase while natural gas and oil production revenues
declined $3.9 million. All of the increase was due to increased demand for
services provided by CDI's DP vessels, particularly the UNCLE JOHN, WITCH QUEEN
and BALMORAL SEA which together contributed 62% of the increase. In addition,
new vessels (SEA SORCERESS and MERLIN) contributed $10.3 million of the
increase. The charter of two Coflexip Stena Offshore vessels, the MARIANOS
during the first quarter and the CONSTRUCTOR in the second, added $8.0 million
to the 1998 revenues.

Natural gas and oil production was $12.6 million in 1998 as compared to
$16.5 million in 1997. The decrease was due to a decline in production from 5.7
BCFE (billion of cubic feet equivalent) during 1997 to 4.9 BCFE in 1998 and a
decline in average gas prices from $2.57/Mcf for 1997 to $2.12/Mcf during 1998.
The decline in production is a result of five wells going off line in the second
quarter and remedial work being delayed into the fourth quarter by a lack of
equipment and then by weather.

GROSS PROFIT. Gross profit increased by $15.5 million, or 46%, from $33.7
million in 1997 to $49.2 million in 1998 with the UNCLE JOHN, WITCH QUEEN and
BALMORAL SEA making up the majority of the increase. The remaining increase was
due to improved demand for the two saturation diving vessels and the vessels
which work in the shallow Gulf of Mexico (from the shore to 300 feet of water).
Subsea and salvage margins increased from 27% in 1997 to 33% during 1998 due
mainly to outstanding offshore performance and demand for the DP vessels.

Natural gas and oil production gross profit was $3.5 million in 1998 as
compared to $8.4 million in the prior year. The decrease was due to the
aforementioned declines in average natural gas prices and production during 1998
as compared to 1997 and to expensive efforts to re-establish production in the
second half of the year.

SELLING AND ADMINISTRATIVE EXPENSES. Selling and administrative expenses
increased $4.6 million to $15.8 million in 1998 as compared to 1997. The $15.8
million includes a $4.5 million provision principally for 1998 incentive
compensation compared to $2.9 million provided in 1997. The remainder of the
increase is due to the addition of new personnel to support the Company's
Deepwater strategy, growth in it base business and to the cost of a supply chain
management consulting project. Selling and administrative costs were 10% of
revenues in 1998, a level identical to that in 1997.

OTHER INCOME AND EXPENSES. The Company recorded $2.6 million in 1998
reflecting its share of earnings of Aquatica, Inc. Net interest income and other
of $1.1 million for 1998 compares to $208,000 of net interest expense and other
for 1997. This improvement was due to the Company remaining debt free since
completion of its initial public offering of common stock in July, 1997.

INCOME TAXES. Income taxes were $13 million in 1998 as compared to $7.8
million for the prior year. The increase was due to the Company's increased
profitability as the effective tax rate remained 35% in both years. Roughly 35%
of the 1998 tax provision was deferred due mainly to increased depreciation in
addition to the Company's Deepwater research and development efforts.

NET INCOME. Net income increased 67% to $24.1 million in 1998 as compared
to $14.5 million in 1997 as a result of factors described above. Diluted
earnings per share increased 48% (19 percentage points less than the net income
increase) in 1998, as compared to 1997, due to the impact on weighted average
common

25

shares outstanding of the new shares issued in the July 1997 IPO.

COMPARISON OF YEAR ENDED DECEMBER 31, 1997 TO YEAR ENDED DECEMBER 31, 1996

REVENUES. Consolidated revenues of $109.4 million in 1997 were 44% more
than the $76.1 million reported during 1996 due primarily to the addition of DP
vessels, improved demand for traditional subsea services and increased natural
gas and oil production. Revenues from DP vessels increased 89% to $47.6 million
in 1997 as compared to prior year due to the full year operations of the

BALMORAL SEA and UNCLE JOHN (vessels placed in service in April and October,
1996, respectively). This increase, combined with stronger market conditions for
surface diving and supply boats offset the impact of seven vessels being out of
service for a combined 40 weeks during the first two quarters of 1997 for
regulatory inspections, preventative maintenance and/or vessel upgrades. In
addition, six weeks of downtime were experienced during the third quarter of
1997 due to a lightning strike on the WITCH QUEEN and an electrical fire on the
CAL DIVER II. During 1996 only two CDI vessels were out of service for any
significant length of time.

Revenue from natural gas and oil production was $16.5 million for the year
ended 1997 from 13 properties as compared to $12.3 million in 1996 from nine
properties. The 1997 revenue benefited from prior year well enhancement efforts.
Average gas sales prices improved slightly in 1997 compared to 1996.

GROSS PROFIT. Gross profit increased by $11.6 million, or 53%, from $22.1
million in 1996 to $33.7 million in 1997. The addition of the UNCLE JOHN and
BALMORAL SEA to the Company's fleet were responsible for over half of the
increase. The remaining increase was due to improved demand for traditional
subsea services and increased natural gas and oil production. Subsea margins
were unchanged between 1997 and 1996 despite the Company encountering
difficulties on a large construction project in the third quarter of 1997 and
the unusually active 1997 regulatory inspection and maintenance program which
resulted in Subsea repair costs of $6.3 million as compared to $3.4 million in
1996.

Natural gas and oil production gross profit was $8.4 million for the year
ended December 31, 1997 as compared to $5.0 million for the prior year. The
increase was due mainly to the acquisition of five blocks during the second half
of 1996 and the gain recorded on the sale of two properties during the second
quarter of 1997.

SELLING & ADMINISTRATIVE EXPENSES. Selling and administrative expenses
increased 35% to $11.2 million in 1997 as compared to 1996. The increase was due
mainly to the addition of new personnel to support the Company's Deepwater
strategy and growth in its base business and to higher levels of Subsea bonuses.
The remainder of the increase was due to the ERT incentive compensation program
whereby key management personnel share in the improved earnings of the natural
gas and oil production segment. Selling and administrative expenses were 10% of
1997 revenues, an improvement from 11% in 1996.

NET INTEREST. Net interest expense decreased by $622,000 (from $745,000 in
1996 to $123,000 in 1997) due mainly to the Company retiring all debt in July
1997 with the proceeds received from the IPO. Borrowings under the Revolving
Credit Agreement averaged $10.4 million during 1997 as compared to $13.0 million
during 1996.

INCOME TAXES. Income taxes were $7.8 million for 1997 as compared to $4.6
million for the prior year. The increase was due to the Company's increased
profitability. Higher depreciation related to the newly acquired DP vessels
resulted in a reduction of the amount of cash taxes paid (as a percentage of
pre-tax income) in 1997 compared to 1996 and also a corresponding increase in
the deferred tax liability.

NET INCOME. Net income increased 72% to $14.5 million for the year ended
December 31, 1997 as compared to $8.4 million in 1996 as a result of factors
described above.


26

LIQUIDITY AND CAPITAL RESOURCES

The Company has historically funded its operating activities principally
from internally generated cash flow, even during industry-depressed years such
as 1992 and 1998. An initial public offering of common stock was completed on
July 7, 1997, with the sale of 2,875,000 shares generating net proceeds to the
Company of approximately $39.5 million, net of underwriting discounts and
issuance costs. The proceeds were used to fund capital expenditures during 1997,
and to repay all outstanding long-term indebtedness. As of December 31, 1998,
the Company had $45.9 million of working capital (including $32.8 million of
cash on hand) and no debt outstanding after funding the equity investment in
Aquatica and $14.9 million of capital expenditures in 1998, which includes ERT's
purchase of six blocks offshore. Subsequent to year end CDI's cash on hand
increased to $42 million at January 31, 1999. Additionally, CDI has
approximately $40 million available under a Revolving Credit Agreement.

OPERATING ACTIVITIES. Net cash provided by operating activities was $35.7
million in 1998, as compared to $22.3 million provided in 1997. This increase is
primarily the result of increased profitability of the Company and a decline in
the level of funding required to fund accounts receivable increases ($5.8
million required in 1997 compared to $900,000 returned in 1998). Other current
assets increased $4.2 million at December 31, 1998 as compared to December 31,
1997 due mainly to the purchases of materials and supplies for the new Full
Field Development program.

The Company experienced improved collections of its accounts receivable
during 1998 as compared to the prior year. Total accounts receivable decreased
$900,000 at December 31, 1998 as compared to December 31, 1997 while revenues
grew 39% in 1998 compared to 1997. The Company's average number of days to bill
and collect its trade receivables decreased by 10 days in 1998 as compared to
1997. While losses from customer inability to pay (bad debt expenses) have
historically been insignificant, the current downturn in commodity prices could
result in bankruptcy or liquidation of certain of the smaller production
companies that operate in the Gulf.

Net cash provided by operating activities was $22.3 million in 1997, as
compared to $7.6 million provided in 1996. This increase was primarily the
result of increased profitability and a decline in the level of funding required
to fund accounts receivable increases ($5.8 million required in 1997 compared to
$15.3 million in 1996). In addition, depreciation and amortization increased as
a result of vessel and natural gas and oil properties acquisitions.

INVESTING ACTIVITIES. Capital expenditures have consisted principally of
strategic asset acquisitions, the assembly of a fleet of DP vessels, including
the WITCH QUEEN, BALMORAL SEA, UNCLE JOHN, SEA SORCERESS and MERLIN,
improvements to existing vessels and the acquisition of offshore natural gas and
oil properties. The Company incurred $14.9 million of capital expenditures
during 1998. In January 1998, ERT acquired interests in six blocks involving two
separate fields from Sonat Exploration Company for $1.0 million and assumption
of Sonat's pro rata share of the related decommissioning liability. The
remaining balance includes costs associated with placing the MERLIN in service
and additions to the SEA SORCERESS in preparation for the Terra Nova project as
well as the cost of new steel and equipment added to the WITCH QUEEN, BALMORAL
SEA and CAL DIVER V during 1998 drydock inspections.

In February 1998, the Company purchased a significant minority equity
investment in Aquatica, Inc. (a surface diving company) for $5.0 million, in
addition to a commitment to lend additional funds of $5.0 million to allow
Aquatica to purchase vessels and fund other growth opportunities. Dependent upon
various preconditions, as defined, the shareholders of Aquatica have the right
to convert their shares into Cal Dive shares at a ratio based on a formula
which, among other things, values their interest in Aquatica and must be
accretive to Cal Dive shareholders.


27

The Company incurred $28.9 million of capital expenditures during 1997.
During the third quarter, the Company acquired a 374 foot by 104 foot
ice-strengthened vessel (the SEA SORCERESS) as a DP conversion candidate. During
the fourth quarter, the Company acquired a 198 foot by 40 foot DP vessel (the
MERLIN) purpose built for long term ROV, survey and coring support. The
remaining capital expenditures included the acquisition of two work class ROVs
from Coflexip, the costs associated with installation of a derrick on the UNCLE
JOHN and the cash portion of the fourth quarter natural gas and oil properties
acquisition discussed below. During 1997, the Company had seven vessels out of
service for either regulatory inspection or upgrade programs compared to only
two during 1996.

During the fourth quarter of 1998, the Company sold two offshore natural
gas and oil properties for approximately $600,000 and during the second quarter
of 1997, the Company sold two offshore natural gas and oil properties for
approximately $1.0 million. These transactions were structured as Section 1031
"Like Kind" exchanges for tax purposes. Accordingly, the cash received was
restricted to use for subsequent acquisitions of additional natural gas and oil
properties.

Since 1993, including the transactions closed subsequent to year end, the
Company has invested $28 million to acquire 35 offshore natural gas and oil
leases. The Company records the amount of cash paid together with the
abandonment liability assumed at the time such properties are acquired. Only the
cash paid at closing is reflected in the Company's statement of cash flows
together with bond and escrow deposits required in connection with these
purchases. The Minerals Management Service requires operators in the Gulf of
Mexico to post an areawide bond of $3 million. Beginning in 1998 the MMS allowed
the Company to utilize an insurance carrier to provide such bonding. In
addition, certain of the purchase and sale agreements have required the Company
to fund portions of the estimated decommissioning liability. Accordingly, the
Company's balance sheet as of December 31, 1998 included $2.4 million of cash
deposits restricted for abandonment obligations. In addition, the Company had
also issued letters of credit totaling $26,000 at December 31, 1998 in lieu of
cash deposits in connection with property acquisitions. In January 1999 and
March 1999, the Company acquired, in three separate transactions, interests in
17 blocks (including 94 wells) and assumed the responsibility to decommission
the properties in full compliance with all governmental regulations. The
decommissioning obligations assumed in these transactions were such that a cash
outlay was not required. The Company has had, and anticipates having additional
discussions with third parties regarding possible acquisitions (including
natural gas and oil properties and vessels). However, the Company can give no
assurance that any such transaction can be completed.

FINANCING ACTIVITIES. The Company has financed seasonal operating
requirements and capital expenditures with internally generated funds,
borrowings under credit facilities, and the sale of Common Stock described
above. The Revolving Credit Agreement, as amended, currently provides for a
$40.0 million revolving line of credit. The Revolving Credit Agreement, which
terminates in December 2000, is secured by trade receivables and mortgages on
the Company's vessels. The Revolving Credit Agreement prohibits the payment of
dividends on the Company's capital stock and contains only one financial
covenant (a fixed charge coverage ratio) and a limitation that debt not exceed
$60 million. Interest on borrowings under the Revolving Credit Agreement is
equal to Prime with incentive pricing thereafter pursuant to a formula based
upon EBITDA (as defined therein). No borrowings were outstanding at December 31,
1998. Letters of credit are also available under the Revolving Credit Agreement
which the Company typically uses if performance bonds are required or, in
certain cases, in lieu of purchasing U.S. Treasury Bonds in conjunction with gas
and oil property acquisitions.
The only financing activity in 1998 represents the exercise of stock
options. During the first two quarters of 1997, the Company repaid $5 million,
net of its borrowings under its Revolving Credit Agreement with Fleet Capital
Corporation and in the third quarter repaid the remaining $20 million
outstanding with proceeds from the initial public offering of common stock.
Also, during the second quarter the Company completed a

28

transaction with Coflexip whereby Coflexip agreed to accept treasury shares as
payment for two ROVs added in February.

CAPITAL COMMITMENTS. In connection with its business strategy, management
expects the Company to acquire or build additional vessels, acquire other assets
such as ROVs, as well as seek to buy additional natural gas and oil properties.
The Company has purchased the thrusters and completed engineering for the
conversion of the SEA SORCERESS to full DP, however, this $30 to $35 million
capital expenditure will not be undertaken until commodity prices and market
conditions improve. The Company has also announced that it is considering
building a new Deepwater construction vessel, the Q4000. Depending upon the size
of any future acquisitions, the Company may require additional debt financing,
possibly in excess of the Revolving Credit Agreement, as amended, or additional
equity financing. Other than building, converting or buying DP vessels,
management believes existing cash balances, the net cash generated from
operations and available borrowing capacity under the Revolving Credit Agreement
will be adequate to meet funding requirements for the next year.

YEAR 2000 READINESS DISCLOSURE

The Company has assessed what computer software will require modification
or replacement so that its computer systems will properly utilize dates beyond
December 31, 1999. The Company has purchased, and has implemented, a new project
management accounting system which is Year 2000 compliant. This system, which
fully integrates all of its modules, provides project managers and accounting
personnel with up-to-date information enabling them to better control jobs in
addition to providing benefits in inventory control and planned vessel
maintenance. CDI's vessel computer DP systems are partially dependent on
government satellites and the government has not yet confirmed that they have
solved Year 2000 data problems. If necessary, the vessels could operate for
sometime safely on redundant systems other than satellite information.
Accordingly, the Company believes that the Year 2000 issue will be resolved in
a timely manner and presently does not believe that the cost to become Year 2000
compliant will have a material adverse effect on the Company's consolidated
financial statements. The foregoing statements are intended to be and are
hereby designated "Year 2000 Readiness Disclosure" within the meaning of the
Year 2000 Information Readiness and Disclosure Act.


ITEM 7A. QUANTITIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of
Cal Dive International, Inc.:

We have audited the accompanying consolidated balance sheets of Cal Dive
International, Inc. (a Minnesota corporation), and subsidiaries as of December
31, 1998 and 1997, and the related consolidated statements of operations,
shareholders' equity and cash flows for the three years in the period ended
December 31, 1998. These consolidated 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Cal Dive
International, Inc., and subsidiaries as of December 31, 1998 and 1997, and the
results of their operations and their cash flows for the three years in the
period ended December 31, 1998, in conformity with generally accepted accounting
principles.
