FREQUENTLY USED TERMS:

     DEEPWATER.  Water depths of greater than 1,000 feet.

     DIVING SUPPORT VESSELS ("DSVS").  Subsea services are typically performed
with the use of specially constructed DSVs, which provide an above water
platform that functions as an operational base for divers, ROVs and specialized
equipment.

     DYNAMIC POSITIONING ("DP").  A DP system allows a vessel to stay in
position without the use of anchors. Satellite based differential global
positioning systems ensure the proper counteraction to wind, current and wave
forces to maintain position.

     REMOTELY OPERATED VEHICLES ("ROVS").  ROVs are robotic vehicles used to
complement, support and increase the efficiency of diving and subsea operations
and for tasks at depths where the use of divers is impossible.

     SATURATION DIVING ("SAT DIVING").  SAT diving, required at 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.

                                   THE COMPANY

GENERAL

     Cal Dive is a leading provider of subsea construction, maintenance and
salvage services to the offshore natural gas and oil industry in the U.S. Gulf
of Mexico (the "Gulf of Mexico" or the "Gulf"). Its services are primarily
performed in support of offshore infrastructure construction projects involving
pipelines, production platforms and risers and subsea production systems.
Through ERT, Cal Dive acquires, operates and produces natural gas and oil from
mature offshore properties, providing 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.

     The Company owns a diversified fleet of nine vessels servicing the offshore
natural gas and oil industry, principally in the Gulf of Mexico. This market is
experiencing strong exploration and development activity levels, including rapid
growth for services in the Deepwater Gulf. Beginning in 1995, Cal Dive acted to
fill a market void by assembling a fleet of dynamically positioned vessels which
serve as work platforms for Deepwater projects. The vessels acquired include a
semi-submersible multi-service vessel (UNCLE JOHN) and two mono-hull DP vessels
(WITCH QUEEN and BALMORAL SEA). Management believes that the limited number of
competing DP vessels in the Gulf affords Cal Dive a key strategic advantage,
which has led to rising utilization for its vessels. In addition, interest in
the Cal Dive fleet has increased among potential customers and alliance partners
evaluating a "fast track" approach to field development.

     In the last twelve months, the Company has positioned itself to work on
full field development projects by entering into a number of strategic
alliances. See "Business -- Strategic Alliances." As part of this strategy, in
April 1997, Cal Dive and certain shareholders sold 32% of its Common Stock to
Coflexip. The companies agreed to form a joint venture to pursue large Deepwater
construction projects in the Gulf (the "Business Cooperation Agreement"). Each
company expects to contribute its expertise to the alliance, with Coflexip
performing engineering, design, and manufacturing of flexible pipe and Cal Dive
providing subsea construction, installation, life of field well services,
abandonment and salvage services. See "-- Recent Developments."

     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. Since that time, the Company's growth
strategy has consisted of three basic elements: (i) identifying 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 business
alliances which fill the market gap.

                                        1
<PAGE>
     This growth strategy has frequently involved expanding beyond the Company's
main contracting base and developing innovative service capabilities to meet
customer needs, including the following significant milestones:

       o   1984 --  SATURATION VESSELS: Custom designed the first DSVs with
                    moonpool deployed SAT diving systems dedicated for use in
                    the Gulf of Mexico.

       o   1986 --  TURNKEY CONTRACTING: Began providing subsea construction
                    work on a fixed price basis enabling customers to better
                    control project costs.

       o   1989 --  SALVAGE OPERATIONS: Chartered, and later acquired, the CAL
                    DIVE BARGE I ("BARGE I") for shallow water salvage
                    operations, a business synergistic with the Company's
                    traditional diving services.

       o   1992 --  NATURAL GAS PRODUCTION: Formed a natural gas production
                    company, ERT, to expand customer options for decommissioning
                    and remediation of mature offshore properties and to expand
                    off-season salvage activity.

       o   1993 --  WELL SERVICING: Added a new upstream service, well servicing
                    and plugging and abandoning ("P&A"), as a complement to
                    the Company's salvage services and to exploit the value of
                    ERT properties through enhanced recovery techniques.

       o   1994 --  DYNAMIC POSITIONING: Chartered a DP DSV for use in the Gulf
                    of Mexico, enabling the Company to work through the winter
                    months and in deeper water. This vessel, the BALMORAL SEA,
                    was subsequently acquired in August 1996.

       o   1995 --  DP DSV: Acquired and enhanced a DP DSV, the WITCH QUEEN, to
                    expand the Company's marine construction and subsea services
                    to include flexible pipelay, umbilical lay, coiled line pipe
                    installation, subsea P&A and ROV support.

       o   1996 --  MULTI-SERVICE VESSEL: Acquired and enhanced a
                    semi-submersible MSV, the UNCLE JOHN, as the cornerstone of
                    the Company's Deepwater strategy, thereby expanding its
                    product line to include geotechnical investigation, J-lay of
                    infield flowlines, installation of flexible and hard
                    jumpers, platform risers, and turnkey field development.

       o   1997 --  STRATEGIC ALLIANCES: Formed an alliance with Coflexip which
                    complements other formal alliance agreements with a team of
                    specialty contractors to provide the Company with access to
                    advanced resources and a full range of services for
                    Deepwater construction projects.

COMPANY STRENGTHS

  DIVERSIFIED FLEET OF VESSELS

     Cal Dive has focused on owning and operating a diversified fleet which
provides a full complement of subsea construction, maintenance, and salvage
project capabilities. This fleet enables the Company to operate in all Gulf of
Mexico water depths where development is currently contemplated. The services
provided by these vessels both overlap and are complementary in a number of
market segments, enabling the Company to deploy its DSVs to areas of highest
utility and margin potential.

                                        2
<PAGE>
  EXPERIENCED PERSONNEL AND TURNKEY CONTRACTING

     The Company believes its highly qualified personnel enable it to compete
effectively in the Gulf's unique "spot market" for offshore construction in
which projects are generally of a short duration and of a turnkey nature. The
Company's personnel have the technical and operational experience to manage
turnkey projects and deliver bids which are priced to achieve targeted
profitability. The Company believes these factors position it well to capitalize
on the trend in the oil and gas industry towards outsourcing additional
responsibility to contractors.

  DEEPWATER TECHNICAL SERVICES

     The Company believes that it has established a unique niche by assembling
the specialized assets, technical personnel and exclusive alliance agreements
that provide a cost effective solution to the rising demand for Deepwater
services. As a result, the Company is able to meet the fast track requirements
of Deepwater development projects.

  MAJOR PROVIDER OF SATURATION DIVING SERVICES

     Cal Dive owns and operates over 50% of the U.S. based SAT DSVs currently
operating in the Gulf of Mexico. In recent years there has been an increasing
level of activity as development of recently discovered Deepwater fields
commences and new Deepwater production is tied into the existing Gulf
infrastructure. Management believes that this trend will result in increasing
demand for SAT diving services.

  LEADER IN SHALLOW WATER SALVAGE OPERATIONS

     Since 1989, the Company has established a leading position in the
decommissioning and remediation of facilities in the shallow water Gulf of
Mexico. The Company expects the demand for this service to increase due to the
significant number of platforms which must be removed in accordance with
government regulations.

  MANAGEMENT OF MATURE NATURAL GAS AND OIL PROPERTIES

     Management believes that Cal Dive is the only company acquiring mature
properties in the Gulf of Mexico with the combined attributes of financial
strength, reservoir engineering and operations expertise and the availability of
company-owned salvage assets, resulting in significant strategic and cost
advantages. The Company has personnel experienced in geology, reservoir and
production engineering and facilities management to support ERT operations,
exploit the value of acquired properties and oversee full field development
projects.

GROWTH STRATEGY

  FOCUS ON THE GULF OF MEXICO

     Cal Dive intends to maintain its current focus on the Gulf of Mexico where
the Company is well positioned to respond to rising market demand for services
in all water depths, including Deepwater. Recent Gulf of Mexico lease sales by
the Minerals Management Service of the Department of the Interior ("MMS")
attracted record bidding levels both in terms of the number of leases bid and
the amount of capital exposed, including a record level of interest in Deepwater
blocks. This has led to new market opportunities as well as increased demand for
the Company's traditional services, as reflected in both higher vessel
utilization rates and operating margins.

  CAPTURE A SIGNIFICANT SHARE OF THE DEEPWATER MARKET

     As Gulf of Mexico Deepwater developments have created a need for new
applications of subsea technology, there is a corresponding need for a new
generation of subsea contractor to develop and deploy that technology.
Management, through its Deepwater Technical Services Group, has targeted a
market niche in which the Company functions as a focal point in the

                                        3
<PAGE>
assembly and delivery of the technology required for Deepwater projects. In
particular, the Company believes that well completion, subsea installation and
infield connection services have become more critical in an era of limited
availability of Deepwater drilling equipment and hardware. The Company's MSV has
the capacity to undertake certain well completion activities, thereby reducing
cost to the operator and freeing-up more expensive drilling rig time. Cal Dive
has also negotiated alliance agreements with a number of specialized contractors
to provide a full range of services necessary to Deepwater subsea construction
projects. The objective of this strategy is to increase the proportion of the
Deepwater field development expenditures captured by Cal Dive while reducing the
project duration and overall cost to the operator.

  CAPITALIZE ON SYNERGIES WITH COFLEXIP

     Cal Dive entered into a strategic alliance with Coflexip to strengthen its
position in the Deepwater Gulf and to respond to the trend toward full field
development services. Management believes that Coflexip and Cal Dive together
offer complementary products and services which significantly expand Cal Dive's
ability to provide full field development and life of field services. Coflexip
is a world leader in the design and manufacture of flexible pipe and umbilicals
and is one of the leading subsea construction contractors. Headquartered in
Paris, France, Coflexip employs approximately 3,500 employees spread over five
continents. In 1996, Coflexip had sales of $945 million and total assets of $1.1
billion at year-end.

  OFFER FULL FIELD DEVELOPMENT SERVICES

     Management believes that the significant number of new leases, the number
of Deepwater leases due to expire by 2000 and shortages of well completion
equipment, drilling rigs and production infrastructure will create demand for
fast track, full field development solutions. Cal Dive's recent asset
acquisitions and its personnel and technical expertise, combined with strategic
alliances, put the Company in a strong competitive position to respond to this
market need. In addition, the Company intends to apply the technologies and
capabilities developed for the Deepwater to the "midwater" Gulf (500 to 1,000
feet) as a cost effective alternative to fixed platforms.

  EXPAND THE COMPANY'S NATURAL GAS AND OIL PRODUCTION

     Management believes Cal Dive's reputation in the industry and its
experience in decommissioning and remediation work make the Company a preferred
buyer of mature natural gas and oil properties. The Company intends to exploit
its recent experience managing heavy lift salvage to expand the number of mature
offshore properties for which the Company will bid. In addition, the Company
will continue, on a selective basis, to acquire non-operated working interests
in fields where there is the potential of Cal Dive being awarded the salvage
work.

RECENT DEVELOPMENTS

  PURCHASE OF STOCK BY COFLEXIP AND BUSINESS COOPERATION AGREEMENT

     In April 1997, certain members of management, other shareholders and the
Company sold an equity interest of approximately 32% of Company Common Stock to
Coflexip for $35 million. As part of this transaction, the Company also acquired
two heavy work class construction ROVs manufactured by Coflexip's Perry Tritech
subsidiary, thereby re-establishing ROVs in Cal Dive's product line. Coflexip
and Cal Dive also entered into the Business Cooperation Agreement for combined
services to be offered on Gulf projects exceeding $25 million in value and
meeting certain other criteria. The entity contemplated by the Business
Cooperation Agreement is expected to be formed by June 30, 1997. See
"Business -- Coflexip Strategic Alliance."

                                  RISK FACTORS

     AN INVESTMENT IN THE COMMON STOCK OFFERED HEREBY INVOLVES A HIGH DEGREE OF
RISK. PROSPECTIVE INVESTORS SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS
IN ADDITION TO THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS.

INDUSTRY VOLATILITY

     The Company's subsea and abandonment activities depend on offshore natural
gas and oil exploration, development and production expenditures, which are
dependent on natural gas and oil prices. The level of exploration and
development activity has traditionally been volatile as a result of fluctuations
in natural gas and oil prices and their uncertainty in the future. A significant
or prolonged reduction in natural gas or oil prices in the future would likely
depress offshore drilling and development activity, reduce the demand for the
Company's services and could have a material adverse effect on the Company's
financial condition and results of operations. See "Business -- The Industry"
and "Business -- Natural Gas and Oil Operations."

VESSEL OPERATING RISKS

     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.
Litigation arising from such an occurrence may result in lawsuits asserting
large claims. The Company maintains such insurance protection as it deems
prudent, including 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 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 that it considers
reasonable. See "Business -- Insurance and Litigation."

SEASONALITY

     Marine operations conducted in the Gulf of Mexico are seasonal and depend,
in part, on weather conditions. Historically, Cal Dive has enjoyed its highest
vessel utilization rates during the third and fourth quarters 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. Accordingly, the results of any one quarter are not necessarily
indicative of annual results or continuing trends. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

CONTRACT BIDDING RISKS

     A majority of the Company's projects are performed on a qualified turnkey
basis. The revenue, costs and gross profit realized on a contract can vary from
the estimated amount because of changes in offshore job conditions and
variations in labor and equipment productivity from the original estimates. In
addition, between April 15 and October 15, the Company typically bears the risk
of delays caused by adverse weather conditions other than those resulting from
named tropical storms. These variations and risks inherent in the marine
construction industry may result in the Company experiencing reduced
profitability or losses on projects.

UNCERTAINTY OF ESTIMATES OF NATURAL GAS AND OIL RESERVES

     This Prospectus 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, 1996 by Miller & Lents that relies upon
various assumptions, including assumptions

                                        8
<PAGE>
required by the Securities and Exchange Commission (the "Commission") as 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
reserves set forth in this Prospectus. See "Business -- Natural Gas and Oil
Operations."

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 with respect
to offshore properties, the additional hazards relating to, or loss from, severe
weather. In accordance with industry practice, the Company maintains insurance
against some, but not all, of the risks described above. See
"Business -- Insurance and Litigation."

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
international companies relocate vessels to the Gulf of Mexico, levels of
competition may increase and the Company's business could be adversely affected.
See "Business -- Competition."

CUSTOMER CONCENTRATION

     The Company's customers consist primarily of major, well-established oil
and pipeline companies and independent oil and gas producers. During 1996, the
Company derived approximately 24% of its contract revenue from one customer.
While the Company 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 the Company's operating performance. See "Business -- Customers."

DEPENDENCE ON KEY PERSONNEL

     The Company's success depends on the continued active participation of key
management personnel. The loss of key people could adversely affect the
Company's operations. The Company has two-year employment and non-compete
agreements with each of Messrs. Owen Kratz, Gerald G. Reuhl and S. James Nelson
and six of its senior officers. The Company has also obtained and is the sole
beneficiary under key person life insurance policies with Messrs. Kratz and
Reuhl, each in the amount of $6 million. The Company believes that its success
is also dependent upon its ability to employ and retain skilled personnel. See
"Management."

REGULATORY AND ENVIRONMENTAL MATTERS

     The Company's subsea construction, inspection, maintenance, salvage, and
abandonment operations and its natural gas and oil production from offshore
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 the Company. Significant fines and penalties may be imposed
for non-compliance. See "Business -- Government Regulation" and
"Business -- Environmental Regulations."

<PAGE>
ABSENCE OF A PRIOR PUBLIC TRADING MARKET; POSSIBLE VOLATILITY OF MARKET PRICE;
DILUTION

     Prior to this Offering, there has been no public market for the Common
Stock. Although the Company has applied for quotation of the shares of Common
Stock offered hereby on the Nasdaq National Market, there can be no assurance
that an active public market will develop or be maintained for the Common Stock.
The initial public offering price will be determined by negotiations among the
Company, the Selling Shareholders and the Underwriters. For the factors
considered in such negotiations, see "Underwriting." There can be no assurance
that future market prices will equal or exceed the initial public offering price
set forth on the cover page of this Prospectus. Following this Offering, the
market price of the Common Stock may fluctuate depending on various factors,
including the general economy, stock market conditions, general trends in the
oilfield services industry, announcements by the Company or its competitors and
variations in the Company's quarterly and annual operating results. Purchasers
of the Common Stock offered hereby will experience an immediate and substantial
dilution in the net tangible book value per share. In addition, to the extent
equity financing is pursued by the Company in connection with the acquisition or
building of additional vessels, dilution may occur to investors. See
"Dilution."

VOTING CONTROL BY PRINCIPAL SHAREHOLDERS

     After giving effect to this Offering, the current shareholders of the
Company will own approximately      % of the outstanding Common Stock (     % if
the Underwriters' over-allotment option is exercised in full). The current
shareholders are parties to a shareholders agreement which, among other things,
provides for the election of directors. As a result, the current shareholders
may be able to control the outcome of certain matters requiring a shareholder
vote, including the election of directors. See "Business -- Coflexip Strategic
Alliance," "Certain Relationships and Related Transactions" and "Principal
and Selling Shareholders."

ABSENCE OF DIVIDENDS

     The Company has never paid cash dividends on its Common Stock and intends
for the foreseeable future to retain any earnings otherwise available for
dividends for the future operation and growth of the Company's business. In
addition, the Company's financing arrangements prohibit the payment of cash
dividends on its capital stock. See "Dividend Policy."

SHARES ELIGIBLE FOR FUTURE SALE

     Upon completion of this Offering, the current shareholders, directors and
officers of the Company will beneficially own            shares of the Common
Stock, which will represent approximately      % of the then issued and
outstanding shares (     % if the Underwriters' over-allotment option is
exercised in full). The Company, its officers and directors, the Selling
Shareholders, certain other shareholders of the Company and Coflexip have agreed
with the Underwriters not to offer, sell or otherwise dispose of any shares of
Common Stock for 180 days from the date of this Prospectus without the prior
consent of the Representatives of the Underwriters. After the expiration of such
agreement, however, such shareholders may sell shares pursuant to Rule 144 under
the Securities Act of 1933, as amended (the "Securities Act"), or otherwise.
In addition, the current shareholders, including Coflexip, have been granted
demand and "piggyback" registration rights by the Company with respect to all
of the shares of Common Stock owned by them. Although the Company cannot predict
the timing or amount of future sales of Common Stock or the effect that the
availability of such shares for sale will have on the market price prevailing
from time to time, sales of substantial amounts of Common Stock in the public
market following this Offering could adversely affect the market price of the
Common Stock. See "Principal and Selling Shareholders," "Description of
Capital Stock -- Registration Rights" and "Shares Eligible for Future Sale."

ANTI-TAKEOVER CONSIDERATIONS

     The Board of Directors of the Company 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, the Company's Articles of Incorporation divide the
Company's Board of Directors into three classes. Except for a transaction
involving Coflexip (which is specifically excluded), the Company also is subject
to certain anti-takeover provisions of the Minnesota Business Corporations Act
("MBCA"). In addition, the Company is a party to a Shareholders Agreement that
provides Coflexip with a right of first refusal in connection with certain
acquisition proposals for the Company. 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 the
Company, 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. See "Description of Capital
Stock -- Certain Anti-Takeover Provisions" and "Certain Relationships and
Related Transactions."

                                   THE COMPANY

     Cal Dive is a leading provider of subsea construction, maintenance and
salvage services to the offshore natural gas and oil industry in the Gulf of
Mexico. In July 1990, the Company was purchased by a group of investors
including current management and key employees. In September 1992, Cal Dive
formed ERT as a wholly owned subsidiary, to purchase producing offshore natural
gas and oil properties which are in the later stages of their economic lives. In
January 1995, First Reserve Corporation ("First Reserve"), on behalf of
certain of the investment funds it manages, acquired 50% of the Company's Common
Stock. In April 1997, Coflexip purchased approximately 32% of the Company's
Common Stock. Most of the Company's senior and middle operations management have
been actively involved with Cal Dive since the mid-1980s.

     The Company was organized under the laws of Minnesota in June 1990. The
principal executive offices of the Company are located at 13430 Northwest
Freeway, Suite 350, Houston, Texas 77040, and its telephone number is (713)
690-1818.

                                USE OF PROCEEDS

     The net proceeds from the sale of the shares of Common Stock offered by the
Company (assuming an initial public offering price of $      per share) will be
approximately $      million ($      million if the Underwriters' over-allotment
option is exercised in full). Of such net proceeds, the Company intends to repay
indebtedness incurred in connection with the purchase of the UNCLE JOHN and the
BALMORAL SEA, to fund capital improvements to the UNCLE JOHN and other vessels
and for the purchase of natural gas and oil properties. Any remaining net
proceeds will be used for other general corporate purposes and the possible
purchase of additional vessels. Pending such uses, the Company intends to invest
the net proceeds of this Offering in short-term investment grade, interest
bearing securities. As of December 31, 1996, borrowings under the Company's
Amended Loan and Security Agreement with Fleet Capital Corporation (the
"Revolving Credit Agreement") which matures in December 2000, had an aggregate
outstanding principal balance of $25 million, bearing interest at rates of 7.37%
($22 million) and 8.75% ($3 million). In April 1997, the Company and Fleet
Capital Corporation amended the Revolving Credit Agreement to, among other
things, (i) increase the credit line to $40 million, (ii) reduce the interest
rate, (iii) release liens on ERT properties and (iv) reduce the financial
covenants from four to two (a fixed charge coverage ratio and a $60 million debt
limitation). The Company will not receive any of the proceeds from the sale of
shares of Common Stock by the Selling Shareholders. See "Principal and Selling
Shareholders" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations."

                                DIVIDEND POLICY

     The Company has never paid cash dividends on its Common Stock and does not
intend to pay cash dividends in the foreseeable future. The Company currently
intends to retain earnings, if any, for the future operation and growth of its
business. In addition, the Company's financing arrangements prohibit the payment
of cash dividends on its capital stock. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."

                                    DILUTION

     The net tangible book value of the Company at December 31, 1996, was
$       or $       per share of Common Stock. Net tangible book value per share
of Common Stock is determined by dividing the tangible net worth (total tangible
assets less total liabilities) of the Company by the              shares of
Common Stock outstanding prior to the consummation of this Offering. After
giving effect to the sale of Common Stock by the Company in this Offering
(assuming no exercise of the Underwriters' over-allotment option and net
proceeds to the Company of $           ), the pro forma net tangible book value
of the Company at December 31, 1996, would have been approximately $       or
$       per share of Common Stock. This represents an immediate increase in net
tangible book value of $       per share of Common Stock to present holders of
Common Stock and an immediate dilution of approximately $       per share to new
investors purchasing shares in this Offering. The following table illustrates
this per share dilution to new investors:

     The above computations do not give effect to the 911,500 shares issuable
pursuant to outstanding stock options, all of which are exercisable at exercise
prices ranging from $      to $      per share. To the extent any options are
exercised in the future at an exercise price less than the initial public
offering price, there will be further dilution to new investors. See

                     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. Cal Dive's construction services
generally follow successful drilling activities by six to eighteen months. The
level of drilling activity is related to both short and long-term trends in
natural gas and oil prices. A decline in natural gas and oil prices generally
leads to a reduction in offshore drilling activity which can lower demand for
construction services. Recently, this relationship has been less pronounced due
to a number of industry trends, including advances in technology that have
increased drilling success rates and efficiency, and a worldwide growth in the
demand for both natural gas and oil. The number of offshore rigs working in the
Gulf of Mexico has averaged close to practical full utilization since mid-1995
which management expects will lead to increased construction activity over the
next several years. Given worldwide shortages of drilling rigs, subsea hardware
and experienced personnel, efforts to drill Gulf of Mexico leases on a timely
basis have accelerated demand for the Company's subsea services resulting in
improved pricing.

     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 tended to reduce the number of mature properties available
for sale, these higher prices contributed to improved operating results for the
Company in 1996.

     Salvage operations consist of platform decommissioning, removal and
abandonment, P&A services performed by the Company's 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 one year from the date
production ceases and also require remediation of the seabed at the well site to
its original state. In 1996, the Company contracted and managed, on a turnkey
basis, all aspects of the decommissioning and abandonment of certain fields for
two major oil companies using third party heavy lift derrick barges, a service
the Company intends to expand in the future.

     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

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 approximately 60 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, Cal Dive 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.

RESULTS OF OPERATIONS

  COMPARISON OF YEAR ENDED DECEMBER 31, 1996 TO YEAR ENDED DECEMBER 31, 1995

     REVENUES.  Consolidated revenues of $76.1 million in 1996 were more than
double the $37.5 million reported in the prior year due primarily to the
addition of new DP vessels and to higher commodities prices and increased
production from natural gas and oil properties. A full year of operations from
the WITCH QUEEN (placed in service in November 1995) and the additions of the
BALMORAL SEA and UNCLE JOHN increased revenues from the DP vessels to 33% of
consolidated 1996 revenues compared to 10% in 1995. This trend is expected to
continue in 1997 because the Company will have full year operations from the
BALMORAL SEA and UNCLE JOHN, which were only in service for eight and two
months, respectively, in 1996. The establishment of a new management team
resulted in improved performance in the operation of the salvage assets (BARGE I
and well servicing equipment) which included the removal of four large
structures by subcontracting heavy lift barges. Natural gas and oil production
from 14 offshore blocks owned at year-end 1996 was $12.3 million compared to
$4.8 million in 1995. This increase of $7.5 million, or 156%, was a result of
natural gas prices increasing by approximately 58% and to production from the
five properties acquired in 1996 as well as the full year contributions of the
Company's other properties.

     GROSS PROFIT.  Gross profit increased by $13.2 million in 1996, from $8.8
million in 1995 to $22.1 million in 1996. Improved rates and performance on
turnkey contracts resulted in subsea and salvage margins increasing from 22% in
1995 to 27% in 1996. This increase reflects in part the benefit of operating
five specialized SAT vessels. Gross profit from salvage assets was $2.2 million
in 1996 or 13% of that generated by subsea and salvage operations in contrast to
"break-even" results for the prior year. Natural gas and oil production gross
profit was $5.0 million in 1996 compared to $1.7 million in the prior year, with
the $3.3 million increase resulting from higher natural gas prices and greater
production levels.

     SELLING AND ADMINISTRATIVE EXPENSES.  Selling and administrative expenses
increased 68% in 1996 to $8.3 million from $4.9 million in 1995. Payments of
$2.3 million were made to 223 offshore, supervisory and management personnel
under 1996 incentive plans (an increase of $2.0 million over 1995). The balance
of the increase reflects higher sales and administrative costs necessary to
support the 103% increase in 1996 revenues.

     NET INTEREST.  Net interest expense increased by $610,000 (from $135,000 in
1995 to $745,000 in 1996) due to the borrowings incurred in conjunction with the
acquisition of the BALMORAL SEA and UNCLE JOHN. Borrowings under the Revolving
Credit Agreement averaged $13 million in 1996 compared to $6 million in 1995.

     INCOME TAXES.  Income taxes of $4.6 million compares to $1.0 million in
1995 as a result of significant increases in 1996 margins and profitability. The
effective tax rate increased significantly, from 28% to 35% because the Company
no longer qualified for the "Small Producer" tax benefit of percentage
depletion. Higher depreciation related to the new DP vessels had the result of
reducing the amount of cash taxes paid. In 1996, cash payments for Federal
income taxes were $2.2 million or 48% of the total $4.6 million tax provision.

     NET INCOME.  In 1996, net income of $8.4 million increased $5.8 million, or
215%, from 1995 as a result of the factors described above.

  COMPARISON OF YEAR ENDED DECEMBER 31, 1995 TO YEAR ENDED DECEMBER 31, 1994

     REVENUES.  During 1995, the Company's revenues decreased $500,000 to $37.5
million compared to $38 million in 1994. A $2.5 million increase in natural gas
and oil revenues offset decreases in subsea services, particularly derrick barge
and well servicing revenues, which together decreased $1.3 million. The increase
in natural gas and oil revenues was due to the Company's acquisition of seven
offshore properties in 1995. The Company's subsea revenues in 1995 were
negatively impacted by Hurricanes ROXANNE and OPAL. While dealing with adverse

                                       18
<PAGE>
weather in the Gulf of Mexico is an accepted risk in the marine contracting
business, these storms were unusual in that while little damage was incurred in
the Gulf of Mexico, the Company's vessels were unable to leave the dock for 20
days during what are generally the two busiest months of the year (September and
October). In addition, the number of platforms with two or more piles removed in
the Gulf of Mexico decreased by almost 30% for the year which included a 50%
reduction during the last six months, primarily as a result of contractors
shifting assets to higher margin construction projects. The Company's revenues
in 1995 were also negatively impacted by operating difficulties with the BARGE I
which have been resolved.

     GROSS PROFIT.  Gross profit decreased by $2.2 million in 1995 as compared
to 1994, from $11 million to $8.8 million. Approximately $1.0 million of the
decrease was due to vessel drydockings during 1995 with the balance related to
the down time caused by two hurricanes and operational difficulties with respect
to BARGE I. Three of the Company's vessels, CAL DIVER II, CAL DIVER V and BARGE
I, underwent major U.S. Coast Guard ("USCG") drydock inspections during 1995.
In addition to the work required to maintain the USCG Certificates of
Inspection, the Company completed a major capital upgrade program. As a result,
these three vessels were out of service for a combined aggregate of ten months
during 1995. Natural gas and oil operations contributed 19% of consolidated
gross profit in 1995 as compared to 7% for 1994 due to the increase in the
number of properties owned at December 31, 1995.

     SELLING AND ADMINISTRATIVE EXPENSES.  Selling and administrative expenses
increased 6% to $4.9 million in 1995 compared to $4.7 million in 1994. This
increase was due primarily to improved results in the Company's natural gas and
oil business resulting in an additional $200,000 of incentive compensation
earned by key ERT personnel.

     NET INTEREST.  During 1995, net interest expense declined 69% to $135,000
as compared to $428,000 in 1994. Interest income generated by the cash deposits
set aside to fund abandonment liabilities was $202,000 in 1995, an increase of
$100,000 from 1994.

     INCOME TAXES.  Income taxes of $1 million reflect an effective tax rate of
28.1% in 1995 compared to 30.5% in 1994. The decrease in tax rate was due to the
impact of percentage depletion of natural gas and oil operations comprising a
larger percentage of the Company's 1995 income.

     NET INCOME.  Net income decreased to $2.7 million from $4 million in 1994
as a result of the factors described above.

LIQUIDITY AND CAPITAL RESOURCES

     OPERATING ACTIVITIES.  The Company has historically funded its operating
activities principally from internally generated cash flow, even in an
industry-depressed year such as 1992. Management purchased the Company in July
1990, in a leveraged buyout funded with $10.7 million in debt and $1 million in
equity. By July 1993, cash flow from operating activities enabled the Company to
reduce total debt to $3.5 million while increasing equity to $9 million. In
August 1993, management acquired all of the Common Stock of the Company held by
the two financial institutions that financed the buyout, a transaction which
increased the Company's debt to $8.2 million and reduced equity to $5.1 million.
Internally generated cash flow (EBITDA divided by revenue) was 22%, 18% and 25%
of revenues in 1994, 1995 and 1996. This cash generation, when combined with the
1995 equity infusion from First Reserve and its investment funds, enabled the
Company to formulate and implement its expansion strategy.

     Net cash provided by operating activities was $7.6 million in 1996 compared
to $12.0 million in 1995 with the decrease principally a result of $15.3 million
necessary to fund an increase in trade receivables. Trade receivables increased
140% over the prior year, a level greater than the 103% increase in revenues due
to the significant increase in offshore activity. Depreciation and amortization,
which is included in cost of subsea and salvage sales, also increased by $2.5
million as a result of the new vessel additions. However, as noted previously,
overall subsea and salvage

                                       19
<PAGE>
margins increased from 22% in 1995 to 27% in 1996 notwithstanding higher
depreciation charges. The additional depreciation increased the provision for
deferred income taxes which was $2.1 million in 1996 compared to $600,000 in the
prior year.

     CAPITAL EXPENDITURES.  Capital expenditures consisted principally of
strategic asset acquisitions including the WITCH QUEEN, BALMORAL SEA and UNCLE
JOHN, improvements to existing vessels and the acquisition of offshore natural
gas and oil properties. Since 1993, the Company has invested $17 million to
acquire 15 offshore natural gas and oil properties in seven separate
transactions. 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 MMS requires an operator bond, and 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, 1996 includes $5.2 million of cash deposits restricted for
abandonment obligations which aggregated $6.0 million on that date. In addition
the Company had also issued letters of credit totaling $2.8 at December 31, 1996
in lieu of cash deposits in connection with property acquisitions.

     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. Since 1993, Fleet Capital Corporation has provided all debt funding
pursuant to a Revolving Credit Agreement which initially was $15 million and
which, as amended in April 1997, is currently $40 million. 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, among
other restrictions, certain financial covenants. During 1995 and 1996, those
covenants typically required the Company to (i) maintain income from operations
at specified levels, (ii) limit leverage, as defined, to no more than a
specified ratio of net worth, (iii) maintain certain interest coverage and debt
service ratios, as defined, and (iv) maintain a minimum ratio of current assets
to current liabilities. The Company was in compliance with, or obtained waivers
of default from, the covenants under the Revolving Credit Agreement during 1995
and 1996. The Revolving Credit Agreement, as amended, contains only two
financial covenants (a fixed charge coverage ratio and a limitation that debt
not exceed $60 million). The interest rate during 1996 was equal to the lender's
floating prime rate plus .5%, or the Eurodollar Base Rate plus 2.25% for
borrowings less than $10 million, and 2% if borrowings exceed $10 million.
Pursuant to these terms, borrowings at December 31, 1996 included $22 million at
7.37% (Eurodollar option) and $3 million at 8.75% (prime option). The Revolving
Credit Agreement, as amended, reduces these rates to LIBOR plus 1.75% in 1997
with incentive pricing thereafter pursuant to a formula based upon EBDIT (as
defined therein). 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.

     CAPITAL COMMITMENTS.  In connection with its business strategy, management
expects the Company to acquire or build additional vessels, acquire other assets
such as the ROV purchase from Coflexip, as well as seeking to buy additional
natural gas and oil properties. 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. If the Company seeks equity financing in connection with such
acquisitions, investors in this Offering may experience dilution. Other than
potential asset acquisitions, management believes 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.

                                    BUSINESS

GENERAL

     Cal Dive is a leading provider of subsea construction, maintenance and
salvage services to the offshore natural gas and oil industry in the Gulf of
Mexico. Its services are primarily performed in support of offshore
infrastructure construction projects involving pipelines, production platforms
and risers and subsea production systems. Through ERT, Cal Dive acquires,
operates and produces natural gas and oil from mature offshore properties,
providing customers a cost effective alternative to the decomissioning process.
The Company's customers include major and independent natural gas and oil
producers, pipeline transmission companies and offshore engineering and
construction firms. See Note 10 of the notes to Financial Statements for
financial information with respect to the Company's business segments.

     The Company owns a diversified fleet of nine vessels servicing offshore
natural gas and oil industry, principally in the Gulf of Mexico. This market is
experiencing strong exploration and development activity levels, including rapid
growth in Deepwater. Beginning in 1995, the Company acted to fill a market void
by assembling a fleet of dynamically positioned vessels which serve as work
platforms for Deepwater projects. The vessels acquired include a
semi-submersible multi-service vessel (UNCLE JOHN) and two mono-hull DP vessels
(WITCH QUEEN and BALMORAL SEA). Management believes that the limited number of
competing DP vessels in the Gulf affords the Company a key strategic advantage
which has led to rising vessel utilization for its vessels. In addition,
interest in the Cal Dive fleet has increased among potential customers and
alliance partners evaluating a fast track approach to field development.
Management believes that strong worldwide demand for DP vessels will cause this
trend to continue.

     In the last twelve months, the Company has positioned itself to work on
full field development projects by entering into a number of strategic
alliances. See "-- Strategic Alliances". As part of this strategy, in April
1997, certain shareholders and Cal Dive sold 32% of its Common Stock to Coflexip
and executed the Business Cooperation Agreement. Each company expects to
contribute its separate expertise to the alliance as follows:

  DP construction vessels                            applicable)                

     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. Since that time, the Company's growth
strategy has consisted of three basic elements: (i) identifying 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 business
alliances which fill the market gap.

COMPANY STRENGTHS

  DIVERSIFIED FLEET OF VESSELS

     Cal Dive has focused on owning and operating a diversified fleet which
provides a full complement of subsea construction, maintenance, and salvage
project capabilities. The Company operates a fleet of one semi-submersible DP
MSV (the UNCLE JOHN), two DP DSV's (the WITCH QUEEN and BALMORAL SEA), two
four-point moored saturation DSVs (the CAL DIVER I and II), three other DSVs,
two work class ROVs and a salvage barge. This fleet enables the Company to
operate in all Gulf water depths where development is currently contemplated.
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. The vessels serve as work platforms for
activities performed by divers in water depths of less than 1,000 feet and by
ROVs for projects at all depths. The Company intends to continue to expand the
capabilities of its diversified fleet through the acquisition of additional
vessels and assets.

EXPERIENCED PERSONNEL AND TURNKEY CONTRACTING

     The shortage of experienced personnel has resulted in a trend in the oil
and gas industry of transferring more responsibility to contractors and
suppliers. The Gulf of Mexico spot market is unique in the world in that
projects are typically of short duration and generally of a turnkey nature.
Management believes that a key element of its growth strategy and success has
been its pioneering role in providing turnkey contracting and its ability to
attract and retain experienced industry personnel. The Company personnel have
the technical expertise and operational experience to effectively manage turnkey
projects and thereby deliver bids which are priced to achieve targeted
profitability. Because of its experience with turnkey contracting and its
people, the Company believes it is well positioned as to capitalize on the trend
in the natural gas and oil industry towards outsourcing additional
responsibility to contractors.

  DEEPWATER TECHNICAL SERVICES

     The Company believes that it has established a unique niche in the
Deepwater Gulf by assembling the specialized assets, technical personnel and
exclusive alliance agreements that represent a cost effective solution to the
rising demand for Deepwater services. The Company's mono-hulled DP vessels
provide a flexible work platform to launch ROVs and support subsea construction
in most weather conditions. Likewise, the Company's MSV, the UNCLE JOHN, has
demonstrated its ability to perform certain well completion tasks previously
undertaken using more expensive drilling equipment. These vessels in combination
with the ROVs acquired from Coflexip allow the Company to control key assets
involved in Deepwater subsea construction and field development. Over the last
two years, the Company has employed personnel with experience in Deepwater
subsea construction and ROV operation. Further, the Company has entered into
alliance agreements with a team of specialized contractors that provide access
to necessary equipment, technology and services to meet the fast track
requirements of Deepwater development activities.

  MAJOR PROVIDER OF SATURATION DIVING SERVICES

     Cal Dive owns and operates over 50% of the U.S. based SAT DSVs currently
operating in the Gulf of Mexico. Saturation diving is required for subsea
operations in water depths beyond 300 feet. In recent years there has been an
increasing level of construction activity, a trend which is expected to
accelerate as development of recently discovered Deepwater fields commences and
new Deepwater production is tied into the existing Gulf infrastructure.
Management believes that this trend will result in increasing demand for SAT
diving services.

<PAGE>
  LEADER IN SHALLOW WATER SALVAGE OPERATIONS

     Since 1989, the Company has established a leading position in the
decommissioning and abandonment of facilities in the shallow water Gulf of
Mexico. The Company expects the demand for salvage and P&A services to increase.
Over 75% of the 3,800 platforms in the Gulf of Mexico are over ten years old and
there are approximately 15,000 wells that must ultimately be plugged and
abandoned in accordance with government regulations related to the
decommissioning of offshore production facilities. During 1996, the Company
contracted for and managed, on a turnkey basis, all aspects of the
decommissioning and abandonment of several fields for two major oil companies
utilizing third party heavy lift derrick barges. These projects involved larger
platforms than Cal Dive had historically decomissioned, and represent a service
that management expects to expand in the future.

  MANAGEMENT OF MATURE NATURAL GAS AND OIL PROPERTIES

     The Company 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. The Company has assembled a management team of personnel
experienced in geology, reservoir and production engineering and facilities
management. The Company has acquired interests in 15 mature producing properties
in the last four years, one of which has been plugged and abandoned. Mature
properties are generally those properties where decommissioning and abandonment
costs are significant relative to the value of remaining natural gas and oil
reserves. Cal Dive seeks to acquire properties that it can operate to enhance
remaining production, control operating expenses and manage the cost and timing
of the decommissioning and abandonment of such properties. Management believes
that Cal Dive is the only company acquiring mature properties in the Gulf of
Mexico which combines financial strength, reservoir engineering and operations
expertise with the availability of company-owned salvage assets, resulting in
significant strategic and cost advantages. Since acquiring its initial property
in late 1992, the Company has increased estimated proved reserves to
approximately 24.6 Bcfe at December 31, 1996.

GROWTH STRATEGY

  FOCUS ON THE GULF OF MEXICO

     Cal Dive intends to maintain its primary focus on the Gulf of Mexico where
the Company is well positioned to respond to rising market demand for services
in all water depths, and increasingly to address Deepwater demand. Natural gas
and oil exploration, development and production activity levels in the Gulf of
Mexico have increased significantly as a result of several factors, including:
(i) improvements in exploration technologies such as computer aided exploration
and 3D seismic, which have enhanced reservoir mapping, increased drilling
success rates and led to entirely new prospects such as the "Subsalt" play;
(ii) improvements in subsea completion and production technologies, which have
resulted in increased Deepwater drilling and development; (iii) expansion of the
region's production infrastructure, which has improved the economics of
developing both Deepwater and smaller natural gas and oil fields; and (iv) the
short reserve life characteristic of Gulf of Mexico natural gas production,
which requires continuous drilling to replace reserves and maintain production.
Recent lease sales by the MMS of Gulf of Mexico properties attracted record
bidding levels both in terms of the number of leases bid and the amount of
capital exposed, including a record level of interest in Deepwater blocks. This
has led to new market opportunities as well as increased demand for the
Company's traditional marine services, as reflected in both higher vessel
utilization rates and operating margins.

  CAPTURE A SIGNIFICANT SHARE OF THE DEEPWATER MARKET

     As Gulf of Mexico Deepwater developments have created a need for new
applications of subsea technology, there is a corresponding need for a new
generation of subsea contractor to

                                       23
<PAGE>
develop and deploy that technology. Management, through its Deepwater Technical
Services Group, has targeted a market niche in which the Company functions as a
focal point in the assembly and delivery of technology required for Deepwater
projects. In particular, well completions, subsea installation and infield
connection services are more critical in an era of limited availability of
Deepwater drilling equipment and hardware. The Company's MSV has the capacity to
undertake certain well completion activities, thereby reducing cost to the
operator and freeing-up more expensive drilling rig time for drilling
operations. Cal Dive has negotiated formal alliance agreements with a number of
specialized contractors to provide a full range of services necessary to
Deepwater construction projects. These strategic alliances include the recent
Coflexip transaction and agreements with Schlumberger, Shell Offshore, Inc.,
Reading & Bates Development Co., Fugro-McClelland Marine GeoSciences, Inc.,
Sonat, Inc. and Quality Tubing, Inc. 5Cal Dive is also a preferred installation
contractor to Total Offshore Productions Systems ("TOPS"), a company formed by
Reading & Bates Development Co. and Intec Engineering, Inc. to conduct Deepwater
full field development projects. The objective of Cal Dive's strategy is to
increase the proportion of Deepwater field development expenditures captured by
Cal Dive while reducing overall costs and project duration for the operator.

  CAPITALIZE ON SYNERGIES WITH COFLEXIP

     Cal Dive entered into a strategic alliance with Coflexip to strengthen its
position in the Deepwater Gulf and to respond to the trend toward full field
development services. Management believes that Coflexip and Cal Dive together
offer complementary products and services which significantly expand Cal Dive's
ability to provide full field development and life of field services. Coflexip
is a world leader in the design and manufacture of offshore flexible pipe and
umbilicals and is one of the leading subsea construction contractors.
Headquartered in Paris, France, Coflexip employs approximately 3,500 employees
spread over five continents. In 1996, Coflexip had sales of $945 million and
total assets of $1.1 billion at the end of the year.

  OFFER FULL FIELD DEVELOPMENT SERVICES

     Management believes the significant number of new leases, the number of
Deepwater leases due to expire by 2000 and shortages of well completion
equipment, drilling rigs and production infrastructure will create a demand for
fast track, full field development solutions. Cal Dive's recent acquisitions of
assets and its personnel and technical expertise, combined with strategic
alliances, put the Company in a strong competitive position to respond to this
market need. In addition, the Company intends to apply the technologies and
capabilities developed for Deepwater to "midwater" Gulf (500 to 1,000 feet) as
a cost effective alternative to fixed platforms.

  EXPAND THE COMPANY'S NATURAL GAS AND OIL PRODUCTION

     Management believes Cal Dive's reputation in the industry and its size and
experience in salvage and remediation work make the Company a preferred buyer of
mature natural gas and oil properties. Specifically, customers can sell an
offshore property at a reasonable price with the assurance that the offshore
property will be decommissioned and abandoned in accordance with regulatory
requirements. The Company intends to exploit its recent experience contracting
and managing heavy lift salvage to expand the number of mature offshore
properties for which the Company will bid. In addition, the Company will
continue, on a selective basis, to acquire non-operated working interests in
fields where there is the potential of Cal Dive being awarded decommissioning or
development work. These fields expand the universe of potential ERT property
acquisitions.

THE INDUSTRY

  BACKGROUND

     The subsea services industry in the Gulf of Mexico originated in the early
1960s to assist natural gas and oil companies with their offshore operations.
The industry has grown significantly

                                       24
<PAGE>
since the early 1970s as these companies have increasingly relied upon offshore
fields for production. Subsea services are required throughout the economic life
of an offshore field and include at various phases 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.

     The industry has grown principally due to the economic benefits of new and
advanced technologies and custom designed equipment and recently has focused
more on Deepwater projects and the integrated "full field development" service
concept described below.

  FULL FIELD DEVELOPMENT

     The Company and its alliance partners can offer oil and gas companies a
range of services from subcontracting to complete field development solutions.
In offering field development services, Cal Dive and its partners intend to
provide a full range of subsea systems and services, from procurement and
installation of flowlines, wellheads, control systems, umbilicals and manifolds
to installation and commissioning of the complete production system.

     Many oil and gas companies prefer to contract with a consortium capable of
undertaking major portions or all of an entire field development project.
Contracting for engineering, procurement, installation and commissioning
("EPIC") services can relieve a customer of substantially all of the burdens
of management of field development and thereby avoid many of the risks inherent
in traditional contracting strategies. Field development partnerships can also
allow oil and gas companies to increase outsourcing of development work. EPIC
contracting for field development projects requires that contractors offer a
full range of services to customers. The Company's strategic alliances provide
Cal Dive with the necessary capabilities to pursue field development contracts.

  OPERATIONS AND EQUIPMENT

     SUBSEA CONSTRUCTION VESSELS.  Subsea services are typically performed with
the use of specialized subsea construction vessels which provide an above water
platform that functions as an operational base for divers in water depths up to
1,000 feet and ROVs at all water depths. Distinguishing characteristics of
subsea construction vessels include DP systems, SAT diving capabilities, deck
space, deck load, craneage and moonpool launching. Deck space, deck load and
craneage are important features of the vessel's ability to transport and
fabricate hardware, supplies and equipment necessary to complete subsea
projects. Vessels with greater deck space and load capacities have the
flexibility to service more complex projects in deeper water. A moonpool is a
structure built into the center of the vessel, which enables safe and efficient
launching of ROVs and SAT diving systems in harsh weather conditions. These
characteristics will generally dictate the types of jobs undertaken and the
conditions and water depths in which the vessel is capable of working.

     DYNAMIC POSITIONING.  DP systems allow a vessel to maintain position
without the use of anchors, and therefore enhance productivity in extreme
weather conditions and are preferred for Deepwater applications. Computer
controlled thrusters mounted on the vessel's hull ensure the proper
counteraction to wind, current and wave forces to maintain position. Since no
anchors are required, risks associated with objects snagging on pipelines or
other underwater structures are

                                       25
<PAGE>
minimized. The capabilities provided by the Company's DP vessels have allowed
Cal Dive to penetrate new markets and provide additional services to the
Deepwater market such as flexible pipelay, well servicing, coring and general
field support.

     REMOTELY OPERATED VEHICLES.  ROVs are robotic vehicles used to complement,
support and increase the efficiency of diving and subsea operations and at
depths for tasks where the use of divers is uncompetitive or impossible. One of
the ROVs acquired from Coflexip will be permanently installed on the UNCLE JOHN.
The second ROV will be a mobile system working on the other Cal Dive vessels.
The Company believes that purchasing ROVs will enable it to better control the
quality and cost of its services, replacing the need to rely upon third party
equipment and personnel for critical path operations.

     SATURATION DIVING.  Subsea operations are conducted by manned or unmanned
intervention. SAT diving, required at 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. The divers are transferred from the
surface to the work site by a diving bell. After completion of the work, the
bell is lifted back to the DSV and the divers return to the chamber to be
replaced by a new group of divers who are lowered to the job site to continue
the work. SAT diving systems allow for continuous operations to be conducted 24
hours a day. The primary advantage of SAT diving is that divers can remain under
pressure and make repeated dives for extended periods before beginning
decompression. Overall productivity and safety is therefore enhanced due to
fewer decompressions, diver continuity and a lower likelihood of delays caused
by adverse weather conditions.

     SURFACE DIVING.  Surface diving is the primary diving technique performed
in water depths less than 300 feet. Divers are linked to the surface by a diving
umbilical containing compressed air lines and communications equipment. The
diver enters the water directly and descends to the work site, accomplishes the
prescribed tasks and begins to decompress in the water during a gradual ascent
to the surface. The length of time a diver is able to remain at the work site
depends upon, and is limited by, the water depth.

     The following table summarizes the equipment and techniques primarily used
in providing subsea services by water depth:

               EQUIPMENT/                     WATER DEPTH
             TECHNIQUE USED                    (IN FEET)

MARINE VESSELS AND EQUIPMENT

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

     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. Five of the Company's
vessels have been modified to provide saturation diving services. Three of these
vessels were specifically upgraded to respond to the emerging Deepwater market.

(1) The Company's DSVs also meet standards for seaworthiness and safety set by
    the USCG.

(2) This vessel has been 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.

     Under government regulations and the Company'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. The Company 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 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.

     The Company 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
1995 and 1996, the Company incurred approximately $2.4 million and $3.7 million,
respectively, in drydocking, marine inspection and general repair and
maintenance costs. See "-- Government Regulation."

     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. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources."

COFLEXIP STRATEGIC ALLIANCE

  BACKGROUND

     As part of the Company's strategy to strengthen its position in the Gulf of
Mexico Deepwater and to respond to the growing trend towards integrated
contracting of packages of field development services, in April 1997 Cal Dive
entered into a strategic alliance with Coflexip. Coflexip is the worldwide
leader in the design and manufacture of flexible pipe and umbilicals and is a
leading integrated subsea contractor to the offshore oil and gas industry.
Deepwater field developments have shifted toward greater use of subsea and
floating production systems and away from conventional fixed production platform
development systems. As a result, the services and products offered by Companies
such as Cal Dive and Coflexip increasingly are required.

                                       27
<PAGE>
     The alliance consisted of Coflexip acquiring approximately 32% of the
Common Stock of the Company, pursuant to a purchase agreement dated as of April
11, 1997 (the "Purchase Agreement") and entering into the Business Cooperation
Agreement. See "Certain Relationships and Related Transactions." In connection
with the closing under the Purchase Agreement, Coflexip and the Company entered
into certain related agreements, including two-year employment agreements with
the Company's nine senior executives, a registration rights agreement,
shareholders agreement and amended the Company's Articles of Incorporation and
By-Laws. See "Management" and "Description of Capital Stock."

  THE BUSINESS COOPERATION AGREEMENT

     As part of the transaction, the companies entered into the Business
Cooperation Agreement which provides that the parties will form a new entity by
June 30, 1997 to which certain assets will be contributed by both parties. The
new entity will be governed by a Board of Directors consisting initially of two
members (one from each company). Cal Dive and Coflexip will bid each project as
a subcontractor to the venture for their respective services. In Cal Dive's case
the services will include ROV operations, diving, coiled line pipe installation,
umbilical and flexible flowline lay operations, riser installation, well
servicing and the provision of DP and other vessels. In Coflexip's case, the
services will include flexible flowline lay, product sales (umbilicals, flexible
pipe and ROVs), EPIC project design and engineering, reeled and rigid pipelay
and providing larger construction vessels. The joint venture will pursue Gulf of
Mexico and Caribbean EPIC projects that require at least one Cal Dive service
and one Coflexip service, where the aggregate contract value of the combined
services involved in the project is at least $25 million, and any such other
projects as the parties may agree as being within the intended scope of the
joint venture.

  COMPLEMENTARY PRODUCTS AND SERVICES

     Management believes that Coflexip and Cal Dive offer highly complementary
products and services and that the strategic alliance with Coflexip
significantly expands Cal Dive's ability to provide full field development and
life of field services. The table below illustrates some of the individual
strengths, products and services offered by Coflexip and Cal Dive that combined
permit them to offer a new approach for Deepwater Gulf Subsea contracting
activities:

  INFORMATION ON COFLEXIP

     Coflexip is a world leader in the design and manufacture of flexible pipe
and umbilicals, and one of the leading subsea contractors to the offshore oil
and gas industry, providing integrated subsea services on large subsea projects
throughout the world. Coflexip was established in 1971 to manufacture and market
flexible pipe designed by the Institute Francais du Petrole (the "IFP"), a
French research and development organization that holds a controlling interest
in one of Coflexip's principal shareholders. In December 1994, Coflexip acquired
Stena Offshore N.V., a contractor providing subsea services to the oil and gas
industry, from Stena International B.V. ("Stena International"), and Stena
International became a significant shareholder of Coflexip.

                                       28
<PAGE>
     Coflexip targets the subsea production systems segment of the subsea
oilfield services industry involving the installation of a wellhead on the
seabed rather than on a platform. Subsea productions systems generally require
flowlines that are less than 12 inches in internal diameter and less than 20
kilometers in length. This segment corresponds with the Company's technological
capabilities and represents its key market.

     Coflexip designs and manufactures offshore flexible pipe, a number of
products that apply similar technology including umbilicals, and ROVs. Coflexip
also performs project management and engineering services in connection with
large subsea contracts, installs rigid and flexible pipes, umbilicals and
provides a number of related services such as lifting, diving and testing. Its
fleet of vessels and equipment is one of the largest and most advanced
technologically in the industry.

     Coflexip has manufacturing and assembly facilities in five countries and
markets its integrated services worldwide. Its principal markets are the North
Sea, (UK and Norwegian sectors), offshore Brazil, the Asia-Pacific region and
other markets including North America and North and West Africa. Coflexip
employs approximately 3,500 employees in five continents and has subsidiaries in
France, the United Kingdom, Brazil, Norway, the United States, Australia and
India.

STRATEGIC ALLIANCES

     Cal Dive has entered into a number of strategic alliances in order to

DEEPWATER TECHNICAL SERVICES GROUP

     The Deepwater Technical Services Group was formed in early 1996 to serve
the emerging Deepwater market. It is intended to be a focal point to assemble
and deliver the varied technological disciplines required for Deepwater
projects. The limited availability of Deepwater rigs makes well completions,
subsea installations and infield connection services take on a more critical
role. Cal Dive acted to fill a market void by assembling a fleet of proven,
dynamically positioned vessels -- a key asset common to the application of
Deepwater technologies. The Company's alliances are managed through this group.
Services covered by Cal Dive's Deepwater Technical Services Group include
geotechnical investigation, turnkey field development, umbilical, controls and
flexible pipe installations, well servicing, P&A, subsea tree installation,
manifold systems, J-lay infield flowlines, ROV flexible and hard jumper
installation by ROVs, subsea piling, pipeline repair systems, catenary and
platform risers, and J-tubes.

NATURAL GAS AND OIL OPERATIONS

     ERT was formed in 1992 in response to a market opportunity to provide a
more efficient solution to offshore abandonment liability and Cal Dive's desire
to expand its off-season salvage and decommissioning activity. Within ERT, the
Company has assembled experienced personnel with proven track records in
geology, reservoir and production engineering as well as offshore facilities
management. Cal Dive generates numerous opportunities to acquire mature
properties through its established contacts in the industry together with the
market's awareness of the Company's comprehensive abandonment management
capability. The Company's property analysis utilizes both the expertise of its
executives and Cal Dive's years of experience in performing turnkey contracts
for decommissioning work. Production is generally sold at prevailing spot market
prices in the Gulf of Mexico. In 1994, 1995 and 1996, revenue from natural gas
and oil production accounted for 6.1%, 12.7% and 16.1%, respectively, of the
Company's total revenues.

     The Company's natural gas and oil business has also been successful because
of regulatory requirements imposed by the MMS which supervises abandonment of
offshore natural gas and oil fields in federal waters. Property owners are
required to bond and/or fund the MMS' estimate of the abandonment liability. The
Company believes its financial ability to meet the MMS' requirements and its
ownership of the required equipment provides it with a competitive advantage
over smaller competitors.

     To maximize the economic value of its properties, Cal Dive uses its
operating expertise to reduce operating costs, maximize production from the
properties and minimize the costs of decommissioning and abandonment. This
technical expertise would enable Cal Dive to take an equity (reserve) position
in conjunction with turnkey field development projects. The Company has acquired
interests in 15 mature producing properties in the last five years, ten of which
are currently in production and one of which has been plugged and abandoned.
Based on the Miller & Lents report, the remaining average useful life of the
current properties is approximately 5.6 years based on 1996 production.

     The table below sets forth information, as of December 31, 1996, with
respect to the Company's estimated net proved reserves and the present value of
estimated future net cash flows at such date, as estimated by Miller & Lents.

     As of December 31, 1996, the Company owned an interest in 48 gross (37.1
net) natural gas wells and one gross (0.5 net) oil well located in federal
offshore waters in the Gulf of Mexico. The Company is responsible for the
payment of abandonment costs on the natural gas and oil properties pro rata to
its working interest. The Company accrues its estimated share of the future
abandonment liabilities on the date the applicable property was purchased. As of
December 31,

                                       30
<PAGE>
1996, the recorded abandonment liability was approximately $6.0 million.
Estimates of abandonment costs and their timing may change due to many factors
including production results, inflation rates, and changes in environmental laws
and regulations.

CUSTOMERS

     The Company's customers are primarily major and independent oil and gas
exploration, transportation and marine construction companies operating in the
Gulf of Mexico. 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 1996 it provided subsea services to approximately
100 customers. For the years ended December 31, 1995 and 1996, approximately 21%
and 24%, respectively, of the Company's total revenues were attributable to J.
Ray McDermott, S.A. The Company's projects are typically of short duration and
are generally awarded shortly before remobilization. Accordingly, backlog is not
a meaningful indicator of future activities.

MARKETING

     Contracts for work in the Gulf of Mexico are typically awarded on a
competitive bid basis with customers usually requesting bids on projects several
months prior to commencement. The Company maintains a focused marketing effort
through a 12-person direct sales force operating from Houston, Texas together
with sales offices in Lafayette and New Orleans, Louisiana. Most contracts are
awarded on a turnkey basis, but the Company also performs work on a cost-plus or
day rate basis, or on a combination of such bases.

     The Company sells substantially all of its natural gas under short-term
contracts (maximum of one year in duration) at pricing based on spot market
indexes. Cal Dive has not engaged in hedging transactions.

COMPETITION

     The subsea services industry is highly competitive. Competition for subsea
construction work in the Gulf of Mexico has historically been based on the
location and type of equipment available, ability to deploy such equipment, the
safety and quality of service in recent years and price. While price has been an
important factor in obtaining contracts, the ability to acquire specialized
vessels, to attract and retain skilled personnel, and to demonstrate a good
safety record have also been important competitive factors. The Company's
competitors for shallow water projects include American Oilfield Divers, Inc.
Subsea International, Global Industries Ltd., 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., Subsea International, and J. Ray McDermott, S.A. Other large
foreign based subsea contractors, including Stolt Comex Seaway, S.A. have
announced their intention to perform services in the Gulf. The Company generally
has fewer competitors in Deepwater projects given the more sophisticated vessels
and technology required. The Company believes that its ability to provide a full
range of services and advanced vessels will generally result in less price
competition, higher margins and will enable it to compete effectively,
particularly in water depths greater than 300 feet.

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

                                       31
<PAGE>
evaluate and select suitable properties and to consummate transactions in a
highly competitive environment.

TRAINING AND QUALITY ASSURANCE

     The Company 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 the
Company's safety programs are among the best in the industry.

FACILITIES

     Cal Dive is headquartered at 13430 Northwest Freeway in Houston, Texas. The
Company's subsea and marine services operations are based in Morgan City,
Louisiana. All of Cal Dive's facilities are leased.

     The Company expects shortly to move to a larger and more modern operating
facility near its current facility in Morgan City. The new facility will provide
many advantages when compared to the present location including, more room (28.5
acres), more office space (30,000 square feet), more bulkhead (over 1000 feet)
for vessel repair and maintenance, new warehouses and mechanics buildings and
more parking. This facility is important to enable Cal Dive to manage operations
effectively as it continues to grow. The Company also has sales offices in
Lafayette and New Orleans, Louisiana.

     The Company also expects to move to a new and more modern headquarters in
Houston in July 1997. The facility will have over 30,000 square feet and parking
to house administrative, project engineering, account management, sales and ERT
personnel.

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 USCG, the Environmental Protection Agency, MMS and the U.S. Customs Service,
as well as private industry organizations such as the American Bureau of
Shipping.

     The Company also supports and voluntarily complies with The Association of
American Diving Contractor Standards. The USCG sets safety standards and is
authorized to investigate vessel and during accidents and recommend improved
safety standards, and the U.S. Customs Service is authorized to inspect vessels
at will. As the Company expands its operations to foreign waters, it will also
be subject to regulation by other governments.

     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 or can obtain all
permits, licenses and certificates necessary to the

                                       32
<PAGE>
conduct of its business. The Company is subject to regulation by the Maritime
Administration, USCG and U.S. Customs Services.

     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 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 Outer Continental Shelf ("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 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 for failure to comply with
applicable bonding requirements or other regulations applicable to plugging and
abandonment. 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, and proposed
additional safety-related regulations concerning the design and operating
procedures for OCS production platforms and pipelines. 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 has recently proposed to amend such regulations to prohibit the
flaring of liquid hydrocarbons and oil without prior authorization. Similarly,
the MMS has promulgated other regulations 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. Any such suspension or termination 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 April 1997, after two years of study, the MMS withdrew proposed changes
to the way it values natural gas for royalty payments that would have
established an alternative market-based method to calculate royalties on certain
natural gas sold to affiliates or pursuant to non-arm's length sales contracts.

     Historically, the transportation and sale for resale of natural gas in
interstate commerce have 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

                                       33
<PAGE>
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" as of January 1,
1993.

     Commencing in April 1992, the FERC issued Order Nos. 636, 636-A, 636-B and
636-C (collectively, "Order No. 636"), which, among other things, require
interstate pipelines to "restructure" to provide open-access transportation
separate or "unbundled" from the pipelines' sales of gas. Order No. 636
further requires pipelines to provide open-access transportation on a basis that
is equal for all gas supplies. Order No. 636 could subject the Company to more
restrictive pipeline imbalance tolerances and greater penalties for violations
of those tolerances. The Company does not believe, however, that it will be
affected by Order No. 636 materially differently than other natural gas
producers, gatherers and marketers with which it competes.

     In July 1996, the United States Court of Appeals for the District of
Columbia Circuit largely upheld Order No. 636. Certain issues as well as
individual pipeline restructuring proceedings are still subject to judicial
review, and upon judicial review, the FERC's orders may be remanded or reversed
in whole or part. Consequently, it is difficult to predict Order No. 636's
ultimate effects.

     Additional proposals and proceedings that might affect the oil and gas
industry are pending before various federal and state regulatory agencies and
the courts. 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, and regulations will have a material effect upon the capital
expenditures, earnings, or competitive position of the Company.

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 which are often difficult and costly to comply with and which carry
substantial penalties for failure to comply. For example, state and federal
agencies have issued rules and regulations pursuant to environmental laws that
regulate environmental and safety matters, including restrictions on the types,
quantities, and concentration of various substances that can be released into
the environment in connection with production and abandonment activities and
remedial measures to prevent pollution from current and former operations.
Federal environmental laws include, without limitation, the Clean Water Act, the
Resource Conservation and Recovery Act ("RCRA"), the Comprehensive
Environmental Response, Compensation and Liability Act ("CERCLA"), OCSLA and
the Oil Pollution Act of 1990 ("OPA"). See "Risk Factors -- Government
Regulation."

     The Clean Water Act imposes strict controls on the discharge of pollutants
into the navigable waters of the U.S., and imposes potential liability for the
costs of remediating releases of petroleum and other substances. The Clean Water
Act provides for civil, criminal and administrative penalties for any
unauthorized discharge of oil and other hazardous substances in reportable
quantities and imposes substantial potential liability for the costs of removal,
remediation and damages. Many states have laws which are analogous to the Clean
Water Act and also require remediation of accidental releases of petroleum in
reportable quantities 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. In addition, offshore facilities and vessels operated by the
Company have facility and vessel response plans to deal with potential spills of
oil or its derivatives.

                                       34
<PAGE>
     RCRA regulates the generation, transportation, storage and disposal of
hazardous and non-hazardous wastes, and requires states to develop programs to
ensure the safe disposal of wastes. The Company generates non-hazardous wastes
and small quantities of hazardous wastes in connection with routine operations,
and while certain of its onshore waste handling practices may require upgrading,
management believes that the wastes it generates are generally handled in
substantial compliance with RCRA and analogous state statutes.

     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. In addition,
companies that incur CERCLA liability frequently also confront third party
claims because 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.

     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 an action could have a
material adverse effect on the Company's financial condition and the results of
operations. As of this date, the Company is not the subject of any civil or
criminal enforcement actions under OCSLA.

     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 a facility or vessel, or the lessee or permittee of the
area in which an offshore facility is located. OPA assigns liability to each
responsible party for oil spill removal costs and a variety of public and
private damages from oil spills. While liability limits apply in some
circumstances, a party cannot take advantage of liability limits 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 to cooperate fully in the cleanup. Few defenses
exist to the liability imposed under OPA for oil spills. The failure to comply
with these requirements or inadequate cooperation in a spill event may subject a
responsible party to civil or criminal enforcement actions. Management of the
Company is currently unaware of any oil spills for which the Company has been
designated as a responsible party under OPA and that will have a material
adverse impact on the Company or its operations. OPA also imposes ongoing
requirements on facility operators, such as the preparation of an oil spill
contingency plan. The Company is in the process of updating such plans.

     OPA, as recently amended in 1996, requires the lessee or permittee of the
offshore area in which an oil or natural gas facility is located and which has a
"worst case" oil spill discharge potential of more than 1,000 barrels of oil
to establish and maintain evidence of financial responsibility in amounts
ranging from $10.0 million in specified state waters to $35.0 million in federal
OCS waters to cover liabilities related to an oil spill for which such person is
statutorily responsible. Higher amounts of financial responsibility, up to
$150.0 million, will be required in certain limited

                                       35
<PAGE>
circumstances where the MMS believes such a level is justified by the risks
posed by the quantity or quality of oil that is handled by the facility. On
March 25, 1997, the MMS proposed regulations to implement these financial
responsibility requirements. Under the proposed regulations, the amount of
financial responsibility required for a facility would depend on the worst case
oil spill discharge volume calculated for the facility. For an offshore facility
in OCS waters, worst case discharge volumes of up to 35,000 barrels will require
a financial responsibility demonstration of $35.0 million, while worst case
discharge volumes in excess of 35,000 barrels will require demonstrations
ranging from $70.0 million to $150.0 million, depending on the worst case
volume. Similarly, for an offshore facility in specified state waters, volumes
of up to 10,000 barrels require a financial responsibility demonstration of
$10.0 million, while worst case discharge volumes in excess of 10,000 barrels
but not more than 35,000 barrels will require demonstrations of $35.0 million,
and worst case discharge volumes in excess of 35,000 barrels will require
demonstrations ranging from $70.0 million to $150.0 million, depending on the
worst case volume. The Company cannot predict whether these financial
responsibility requirements under the OPA amendment or proposed rule will result
in the imposition of substantial additional annual costs to the Company in the
future or otherwise materially adversely affect the Company, but the impact is
not expected to be any more burdensome to the Company than it will be to other
similar situated companies involved in oil and gas explorations and production
in the Gulf of Mexico.

     OPA also requires owners and operators of vessels over 300 gross tons to
provide the U.S. Coast Guard with evidence of financial responsibility to cover
the 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 U.S. Coast Guard for all of
the Company's vessels.

     While certain of its onshore waste handling practices may require
upgrading, 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.

INSURANCE AND LITIGATION

     The Company'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. The Company 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
the Company considers financially prudent.

     The Company'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 Cal Dive 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 the Company is underinsured or uninsured could have a material adverse
effect on the Company.

     The Company 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. The Company believes that
the outcome of all such proceedings, even if

                                       36
<PAGE>
determined adversely, would not have a material adverse effect on its business
or financial condition.

EMPLOYEES

     Cal Dive relies on the quality and skill of its workforce and has
successfully hired, trained, and retained highly skilled managers and divers. As
of March 31, 1997, the Company had 385 employees, 93 of which were salaried.
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 is excellent. Of the
Company's employees, 19 persons own shares of the Company's Common Stock and 37
other employees hold options to acquire Common Stock under the Company's 1995

Company's other senior officers substantially similar to the above agreements.

COMPENSATION PURSUANT TO PLANS

  BONUS PLAN

     Cal Dive has established three types of bonus compensation plans, each of
which is based on the Company's performance. The first bonus plan applies to the
three principal executive officers and is determined by the Compensation
Committee. The second bonus plan applies to subsea operating and administrative
personnel. This plan affords covered project management and sales personnel the
ability to participate in a bonus pool division if gross profits exceeds
specified targets and allows operating and administrative personnel to earn up
to 50% of their base salaries. The third plan is applicable to the three
principal employees of ERT and provides for a bonus of between 1% to 10% of net
income before taxes of ERT up to a maximum total of 15% of such net income.

  PROFIT SHARING AND RETIREMENT PLAN

     The Company's Retirement Plan (the "Retirement Plan") is a 401(k) savings
plan. The Retirement Plan permits each employee to become a participant in the
savings plan feature on

                                       41
<PAGE>
January 1, April 1, July 1, or October 1 following the employee's completion of
90 consecutive days of employment.

     Under the Retirement Plan, each active participant may elect, subject to
certain limitations required by law, to defer payment of from 1% to 15% of his
or her compensation. Upon such an election, the Company contributes such
deferred amounts to the Retirement Plan on behalf of such participant. Such
contributions to the 401(k) savings plan are invested according to the
instructions of the participant in investment funds designated by the plan
administrator. Subject to reduction or elimination based on its financial
performance and needs as described in the Plan, the Company's contributions are
determined annually as 50% of each employee's contribution (up to a maximum of
5% of the employee's annual salary).

     Employee contributions to the 401(k) savings plan and earnings thereon are
100% vested at all times. Contributions by the Company to the profit sharing
feature, and earnings thereon, vest based on the participant's years of service
with the Company, vesting 20% after two years of service, increasing to 50% with
three years of service, and becoming 100% vested following four years of
service. All contributions vest, regardless of years of service, upon
termination of employment by reason of death or disability, attainment of age 65
or the termination or discontinuance of the Retirement Plan. After termination
of employment, an employee is entitled to receive a lump-sum distribution of his
or her entire vested interest in the Retirement Plan.

  STOCK OPTION PLAN

     The Company's 1995 Long Term Incentive Plan, as amended (the "Stock Option
Plan") is administered by the Board and provides for grants of incentive and
nonqualified options as defined by the Internal Revenue Code of 1986, as
amended, to employees as determined by the Compensation Committee. The Stock
Option Plan provides that options for a maximum of 10% of the total shares of
Common Stock issued and outstanding may be granted. No options may be granted
under the Stock Option Plan after October 2005. Options granted to employees
under the Stock Option Plan have a maximum term of five years and, subject to
certain exceptions, are not transferable.

     The number and exercise price of options granted to employees will be
determined by the Compensation Committee; provided, however, that (i) the
exercise price of an incentive option may not be less than the fair market value
of the shares subject to the option on the date of the grant, and (ii) the
exercise price of a non-qualified option may not be less than 85% of the fair
market value of the shares subject to the option on the date of the grant. The
Stock Option Plan provides that, upon a change of control, the options
immediately vest and become exercisable.

     To date, options to purchase approximately 911,500 shares of Common Stock
at exercise prices ranging from $4.50 to $9.50 have been granted to 34
employees.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     During the period from 1991 to 1994, the Company loaned $150,000 to each of
S. James Nelson and Owen Kratz. These loans bore an interest rate of 1.5% above
the prime rate per annum and were repaid in full in July 1995. The Company
believes the terms of the loans with Messrs. Nelson and Kratz were at least as
favorable as could have been obtained from unaffiliated third parties.

     DESCRIBED BELOW ARE CERTAIN RELATED AGREEMENTS. THE FOLLOWING DESCRIPTIONS
ARE QUALIFIED IN THEIR ENTIRETY BY REFERENCE TO THE COMPLETE TEXT OF THE
RELEVANT AGREEMENTS, COPIES OF WHICH ARE FILED AS EXHIBITS TO THE REGISTRATION
STATEMENT OF WHICH THIS PROSPECTUS IS A PART AND ARE INCORPORATED BY REFERENCE

share unless the managing underwriters for such offering believe it would affect
the marketability of such offering.

  LIMITATIONS ON TRANSFERS

                          DESCRIPTION OF CAPITAL STOCK

     Cal Dive's Amended and Restated Articles of Incorporation (the "Articles
of Incorporation") provide for authorized capital stock of 60,000,000 shares of
Common Stock, no par value per share, of which              shares will be
outstanding upon completion of this Offering, and 5,000,000 shares of Preferred
Stock, $.01 par value per share ("Preferred Stock"), of which no shares will
be outstanding upon completion of this Offering. The following summary
description of the capital stock of the Company is qualified in its entirety by
reference to the Amended and Restated Articles of Incorporation and the
Company's Amended and Restated Bylaws (the "Bylaws"), a copy of each of which
is filed as an exhibit to the Registration Statement of which this Prospectus
forms a part.

  COMMON STOCK

     The holders of Common Stock are entitled to one vote for each share on all
matters voted on by shareholders, and except as otherwise required by law or as
provided in any resolution adopted by the Board of Directors with respect to any
series of Preferred Stock, the holders of shares of Common Stock exclusively
possess all voting power.

     Subject to any preferential rights of any outstanding series of Preferred
Stock created by the Board of Directors from time to time, the holders of Common
Stock are entitled to such dividends as may be declared from time to time by the
Board of Directors from funds available therefor, and upon liquidation will be
entitled to receive pro rata all assets of the Company available for
distribution to such holders. The Common Stock is not convertible or redeemable
and there are no sinking fund provisions therefor. Holders of the Common Stock
are not entitled to any preemptive rights except under the Shareholders
Agreement. See "Certain Relationships and Related Transactions."

  PREFERRED STOCK

     The Board of Directors of the Company, without any action by the
shareholders of the Company, is authorized to issue up to 5,000,000 shares of
Preferred Stock, in one or more series and to determine the voting rights,
preferences as to dividends and in liquidation and the conversion and other
rights of each such series. There are no shares of Preferred Stock outstanding.
See "-- Certain Anti-Takeover Provisions" with regard to the effect that the
issuance of Preferred Stock might have on attempts to take over the Company.

  REGISTRATION RIGHTS

     The Company has entered into a Registration Rights Agreement with certain
of its current shareholders, including Gerald G. Reuhl, Owen Kratz, S. James
Nelson and the Selling Shareholders, pursuant to which the holders are entitled
to certain demand and "piggyback" rights with respect to the registration of
such shares under the Securities Act. This Registration Rights Agreement
provides that if the Company proposes to register any of its securities under
the Securities Act, the holder is entitled to include shares of Common Stock
owned by such holder in such offering provided, among other conditions, that the
underwriters of any offering have the right to limit the number of such shares
included in such registration. Such registration rights agreements further
provide for registration upon the request of holders of at least 10% of the
shares of Common Stock subject to the agreement. The Selling Shareholders, which
collectively hold 4,492,548 shares of Common Stock, are exercising their
respective registration rights with respect to a portion of the shares held by
them in connection with this Offering. The other shareholders, with the
exception of the Selling Shareholders, have waived their right to include shares
of Common Stock owned by each of them in this Offering. The Company and Coflexip
have entered into a Registration Rights Agreement substantially similar to the
agreement described above.

CERTAIN ANTI-TAKEOVER PROVISIONS

     The Articles of Incorporation and Bylaws contain a number of provisions
that could make the acquisition of the Company by means of a tender or exchange
offer, a proxy contest or otherwise more difficult. The description of such
provisions set forth below is intended to be only a summary

                                       46
<PAGE>
and is qualified in its entirety by reference to the pertinent sections of the
Articles of Incorporation and the Bylaws, copies of which are filed as exhibits
to the Registration Statement of which this Prospectus forms a part.

     CLASSIFIED BOARD OF DIRECTORS; REMOVAL OF DIRECTORS.  The classification of
directors will have the effect of making it more difficult for shareholders to
change the composition of the Board of Directors. At least two annual meetings
of shareholders generally will be required to effect a change in a majority of
the Board of Directors. Such a delay may help ensure that the Company's
directors, if confronted by a shareholder attempting to force a proxy contest, a
tender or exchange offer or an extraordinary corporate transaction, would have
sufficient time to review the proposal as well as any available alternatives to
the proposal and to act in what they believe to be the best interest of the
shareholders. The classification provisions will apply to every election of
directors, however, regardless of whether a change in the composition of the
Board of Directors would be beneficial to the Company and its shareholders and
whether a majority of the Company's shareholders believes that such a change
would be desirable.

     The Articles of Incorporation provide that directors of the Company may
only be removed for cause by the affirmative vote of the holders of 68% of the
voting power of all of the then outstanding shares of stock entitled to vote
generally in the election of directors (the "Voting Stock").

     The classification provisions could also have the effect of discouraging a
third party from initiating a proxy contest, making a tender or exchange offer
or otherwise attempting to obtain control of the Company, even though such an
attempt might be beneficial to the Company and its shareholders. These
provisions could thus increase the likelihood that incumbent directors will
retain their positions. In addition, the classification provisions may
discourage accumulations of large blocks of the Common Stock that are effected
for purposes of changing the composition of the Board of Directors. Accordingly,
shareholders could be deprived of certain opportunities to sell their shares of
Common Stock at a higher market price than might otherwise be the case.

     PREFERRED STOCK.  The Articles of Incorporation authorize the Board of
Directors to establish one or more series of Preferred Stock and to determine,
with respect to any series of Preferred Stock, the terms and rights of such
series, including (i) the designation of the series, (ii) the number of shares
of the series, which number the Board may thereafter (except where otherwise
provided in the certificate of designation) increase or decrease (but not below
the number of shares thereof then outstanding), (iii) whether dividends, if any,
will be cumulative or noncumulative and the dividend rate of the series, (iv)
the dates at which dividends, if any, will be payable, (v) the redemption rights
and price or prices, if any, for shares of the series, (vi) the terms and
amounts of any sinking fund provided for the purchase or redemption of shares of
the series, (vii) the amounts payable on shares of the series in the event of
any voluntary or involuntary liquidation, dissolution or winding up of the
affairs of the Company, (viii) whether the shares of the series will be
convertible into shares of any other class or series, or any other security, of
the Company or any other corporation, and, if so, the specification of such
other class or series or such other security, the conversion price or prices or
rate or rates, any adjustments thereof, the date or dates as of which such
shares shall be convertible and all other terms and conditions upon which such
conversion may be made, (ix) restrictions, if any, on the issuance of shares of
the same series or of any other class or series, and (x) voting rights, if any,
of the shareholders of such series, which may include the right of such
shareholders to vote separately as a class on any matter.

     The Company believes that the ability of the Board of Directors to issue
one or more series of Preferred Stock will provide the Company with flexibility
in structuring possible future financing and acquisitions and in meeting other
corporate needs which might arise. The authorized shares of Preferred Stock, as
well as shares of Common Stock, will be available for issuance without further
action by the Company's shareholders, unless such action is required by
applicable law or the rules of any stock exchange or automated quotation system
on which the Company's securities may be listed or traded.

                                       47
<PAGE>
     Although the Board of Directors has no intention at the present time of
doing so, it could issue a series of Preferred Stock that, depending on the
terms of such series, might impede the completion of a merger, tender offer or
other takeover attempt. The Board of Directors will make any determination to
issue such shares based on its judgment as to the best interests of the Company
and its shareholders. The Board of Directors, in so acting, could issue
Preferred Stock having terms that could discourage an acquisition attempt
through which an acquiror may be otherwise able to change the composition of the
Board of Directors, including a tender or exchange offer or other transaction
that some, or a majority, of the Company's shareholders might believe to be in
their best interests or in which shareholders might receive a premium for their
stock over the then current market price of such stock.

     NO SHAREHOLDER ACTION BY WRITTEN CONSENT; SPECIAL MEETINGS.  The Bylaws
provide that shareholder action can be taken only at an annual or special
meeting of shareholders and prohibit shareholder action by written consent in
lieu of a meeting. The Bylaws provide that special meetings of shareholders can
be called only upon a written request stating the purpose of such meeting
delivered to the Chairman of the Board, the President or the Secretary, and
signed by a member of the Board of Directors. Shareholders are not permitted to
call a special meeting or to require that the Board call a special meeting.
Moreover, the business permitted to be conducted at any special meeting of
shareholders is limited to the business brought before the meeting pursuant to
the notice of meeting given by the Company.

     The provisions of the Articles of Incorporation and the Bylaws prohibiting
shareholder action by written consent may have the effect of delaying
consideration of a shareholder proposal, including a shareholder proposal that a
majority of shareholders believes to be in the best interest of the Company,
until the next annual meeting unless a special meeting is called at the request
of a majority of the Board of Directors or by resolution of the Board or the
Executive Committee thereof. These provisions would also prevent the holders of
a majority of the voting stock from unilaterally using the written consent
procedure to take shareholder action. Moreover, a shareholder could not force
shareholder consideration of a proposal over the opposition of the Board by
calling a special meeting of shareholders prior to the time a majority of the
Board believes such consideration to be appropriate.

     Amendment of Certain Provisions of the Articles of Incorporation and
Bylaws. Under the MBCA, the shareholders have the right to adopt, amend or
repeal the Bylaws and, with the approval of the Board of Directors, the Articles
of Incorporation. The Articles of Incorporation provide that the affirmative
vote of the holders of at least 80% of the voting power of the then outstanding
shares of Voting Stock, voting together as a single class, and in addition to
any other vote required by the Articles of Incorporation or Bylaws, is required
to amend provisions of the Articles of Incorporation or Bylaws relating to: (i)
the prohibition of shareholder action without a meeting; (ii) the prohibition of
shareholders calling a special meeting; (iii) the number, election and term of
the Company's directors; or (iv) the removal of directors. The vote of the
holders of a majority of the voting power of the then outstanding shares of
Voting Stock is required to amend all other provisions of the Articles of
Incorporation. The Bylaws further provide that the Bylaws may be amended by the
Board of Directors or by the affirmative vote of the holders of at least a
majority of the voting power of the then outstanding shares of Voting Stock,
voting together as a single class. These super-majority voting requirements will
have the effect of making more difficult any amendment by shareholders of the
Bylaws or of any of the provisions of the Articles of Incorporation described
above, even if a majority of the Company's shareholders believes that such
amendment would be in their best interests.

     ANTI-TAKEOVER LEGISLATION.  As a public corporation, the Company will be
governed by the provisions of Section 302A.673 of the MBCA. This anti-takeover
provision may eventually operate to deny shareholders the receipt of a premium
on their Common Stock and may also have a depressive effect on the market price
of the Company's Common Stock. Section 302A.673 prohibits a public corporation
from engaging in a "business combination" with an "interested

                                       48
<PAGE>
shareholder" for a period of four years after the date of the transaction in
which the person became an interested shareholder, unless the business
combination is approved in a prescribed manner. A "business combination"
includes mergers, asset sales and other transactions. An "interested
shareholder" is a person who is the beneficial owner of 10% or more of the
corporation's Voting Stock. Reference is made to the detailed terms of Section
302A.673 of the MBCA.

LIMITATION ON DIRECTORS' LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Articles of Incorporation and Bylaws each contain a provision that
eliminates, to the extent currently allowed under the MBCA, the personal
monetary liability of a director to the Company and its shareholders for breach
of his fiduciary duty of care as a director. If a director were to breach the
duty of care in performing his duties as a director, neither the Company nor its
shareholders could recover monetary damages from the director, and the only
course of action available to the Company's shareholders would be equitable
remedies, such as an action to enjoin or rescind a transaction involving a
breach of the fiduciary duty of care. To the extent certain claims against
directors are limited to equitable remedies, this provision of the Articles of
Incorporation may reduce the likelihood of derivative litigation and may
discourage shareholders or management from initiating litigation against
directors for breach of their duty of care. Additionally, equitable remedies may
not be effective in many situations. If a shareholder's only remedy is to enjoin
the completion of the Board of Directors's action, this remedy would be
ineffective if the shareholder does not become aware of a transaction or event
until after it has been completed. In such a situation, such shareholder would
have not effective remedy against the directors.

     All of the foregoing indemnification provisions include statements that
such provisions are not to be deemed exclusive of any other right to indemnity
to which a director or officer may be entitled under any by-law, agreement, vote
of shareholders or disinterested directors or otherwise.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the Common Stock is                   

                         SHARES ELIGIBLE FOR FUTURE SALE

     Upon completion of this Offering, the Company will have shares of Common
Stock outstanding. The shares sold in this Offering (plus any additional shares
sold upon exercise of the Underwriters' over-allotment option) will be freely
tradeable in the public market without restriction or further registration under
the Securities Act, except for any shares purchased by "affiliates" of the
Company, as that term is defined in Rule 144 promulgated under the Securities
Act. The remaining outstanding shares of Common Stock (the "Restricted Shares"),
are deemed to be "restricted securities" within the meaning of Rule 144 and may
be publicly resold only if registered under the Securities Act or sold in
accordance with an eligible exemption from registration, such as Rule 144. Of
the Restricted Shares, approximately shares will be eligible for resale in the
public market immediately, and shares will be eligible for resale commencing in
July 1997, subject in each case to certain volume and other restrictions under
Rule 144.

     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are required to be aggregated), including an affiliate of the
Company, who beneficially owns "restricted securities" acquired from the
Company or an affiliate of the Company at least one year prior to the sale is
entitled to sell within any three-month period a number of shares that does not
exceed the greater of (i) one percent of the then outstanding shares of Common
Stock (          shares based on the number of shares outstanding immediately
after completion of this Offering, assuming no exercise of the Underwriters'
over-allotment option), and (ii) the average weekly reported trading volume of
the Common Stock during the four calendar weeks immediately preceding the date
on which notice of such sale is filed with the Commission, provided certain
manner of sale and notice requirements and requirements as to the availability
of current public information concerning the Company are satisfied (which
requirements as to the availability of current public information are expected
to be satisfied commencing 90 days after the date of this Prospectus). Under
Rule

                                       49
<PAGE>
144(k), a person who has not been an affiliate of the Company for a period of
three months preceding a sale of securities by him, and who beneficially owns
such "restricted securities" acquired from the Company or an affiliate of the
Company at least two years prior to such sale, would be entitled to sell shares
without regard to volume limitations, manner of sale provisions, notification
requirements or requirements as to the availability of current public
information concerning the Company. Shares held by persons who are deemed to be
affiliates of the Company, including any shares acquired by affiliates in this
Offering, are subject to such volume limitations, manner of sale provisions,
notification requirements and requirements as to availability of current public
information concerning the Company, regardless of how long the shares have been
owned or how they were acquired, and, in addition, the sale of any "restricted
securities" beneficially owned by affiliates is subject to the one-year holding
period requirement. As defined in Rule 144, an "affiliate" of an issuer is a
person that directly or indirectly through the use of one or more intermediaries
controls, or is controlled by, or is under common control with, such issuer.

     The Company, its executive officers and directors, the Selling
Shareholders, certain other shareholders of the Company and Coflexip have agreed
that, for a period of 180 days after the date of this Prospectus, they will not,
directly or indirectly, offer, sell, contract to sell, grant any option to sell
or otherwise dispose of, directly or indirectly, any shares of Common Stock (or
securities convertible into or exchangeable for, or any rights to purchase or
acquire, Common Stock, other than options under the Stock Option Plan and upon
exercise of options granted under the Stock Option Plan) without prior written
consent of the Representatives of the Underwriters.

     In connection with the purchase of Common Stock by First Reserve in January
1995 and the purchase of Common Stock by Coflexip in April 1997, the Company
entered into Registration Rights Agreements which include certain demand and
"piggyback" registration rights, on customary terms and conditions, to the
Company's existing shareholders who currently hold an aggregate of
shares of Common Stock. Such registration rights are subject to certain notice
requirements, timing restrictions and volume limitations. See "Certain
Relationships and Related Transactions" and "Description of Capital
Stock -- Registration Rights."

     The Company has granted options to purchase an aggregate of 911,500 shares
of Common Stock under the Stock Option Plan. See "Management -- Compensation
Pursuant to Plans." The Company intends to register under the Securities Act
the shares issuable upon exercise of options granted under the Stock Option Plan
and, upon such registration, such shares will be eligible for resale in the
public market, except that any such shares issued to affiliates are subject to
the volume limitations and other restrictions of Rule 144.

     Prior to this Offering, there has been no public market for the Common
Stock, and no prediction can be made as to the effect, if any, that the sale of
shares or the availability of shares for sale will have on the market price of
the Common Stock prevailing from time to time. Nevertheless, sales of
substantial amounts of the Common Stock in the public market could adversely
affect prevailing market prices and the ability of the Company to raise equity
capital in the future. See "Underwriting."

     The Underwriting Agreement provides that the Underwriters' obligation to
pay for and accept delivery of the shares of Common Stock offered hereby is
subject to certain conditions precedent and that the Underwriters will be
obligated to purchase all such shares, excluding shares covered by the
over-allotment option, if any are purchased. The Underwriters have informed the
Company that no sales of Common Stock will be confirmed to discretionary
accounts.

     The Company has been advised by the Underwriters that they propose
initially to offer the Common Stock to the public at the public offering price
set forth on the cover page of this Prospectus and to certain dealers at such
price, less a concession not in excess of $        per share. The Underwriters
may allow and such dealers may reallow a concession not in excess of $       per
share to certain other brokers and dealers. After the Offering, the public
offering price, the concession and reallowances to dealers and other selling
terms may be changed by the Underwriters.

     The Company and the Selling Shareholders have granted to the Underwriters
an option exercisable for 30 days after the date of this Prospectus to purchase
up to an aggregate of              additional shares of Common Stock to cover
over-allotments, if any, at the same price per share to be paid by the
Underwriters for the other shares of Common Stock offered hereby. If the
Underwriters purchase any such additional shares pursuant to the over-allotment
option, each Underwriter will be committed, subject to certain conditions, to
purchase a number of the additional shares of Common Stock proportionate to such
Underwriter's initial commitment.

     The Company, its directors and executive officers, certain shareholders who
will beneficially own an aggregate of                            shares of the
Common Stock outstanding after the Offering and Coflexip have agreed with the
Representatives, for a period of 180 days after the date of this Prospectus, not
to issue, sell, offer to sell, grant any options for the sale of, or otherwise
dispose of any shares of Common Stock or any rights to purchase shares of Common
Stock (other than stock issued or options granted pursuant to the Company's
stock incentive plans), without the prior written consent of the
Representatives. See "Shares Eligible for Future Sale."

                                       51

     The Company and the Selling Shareholders have severally agreed to indemnify
the Underwriters against certain liabilities that may be incurred in connection
with the sale of the Common Stock, including liabilities arising under the
Securities Act, and to contribute to payments that the Underwriters may be
required to make with respect thereto.

     Prior to this Offering, there has been no public market for the Common
Stock. The initial public offering price for the Common Stock will be determined
by negotiation between the Company and the Representatives. Among other factors
considered in determining the public offering price will be prevailing market
and economic conditions, revenues and earnings of the Company, the state of the
Company's business operations, an assessment of the Company's management and
consideration of the above factors in relation to market valuation of companies
in related businesses and other factors deemed relevant. There can be no
assurance, however, that the prices at which the Common Stock will sell in the
public market after the Offering will not be lower than the public offering
price.

     In order to facilitate the Offering of the Common Stock, the Underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the Common Stock. Specifically, the Underwriters may overallot in
connection with the Offering, creating a short position in the Common Stock for
their own account. In addition, to cover overallotments or to stabilize the
price of the Common Stock, the Underwriters may bid for, and purchase, shares of
Common Stock in the open market. Finally, the underwriting syndicate may reclaim
selling concessions allowed to an underwriter or a dealer for distributing the
Common Stock in the Offering, if the syndicate repurchases previously
distributed Common Stock in transactions to cover syndicate short positions, in
stabilization or otherwise. Any of these activities may stabilize or maintain
the market price of the Common Stock above independent market levels. The
Underwriters are not required to engage in these activities, and may end any of
these activities at any time.

     In connection with the Coflexip transaction, Schroder Wertheim & Co.
Incorporated provided advisory services to Coflexip for which it has received
customary compensation. From time to time, Simmons & Company International has
provided advisory services to the Company and First Reserve for which it has
received customary compensation.

     The Company has filed an application for quotation of its Common Stock on
the Nasdaq National Market under the symbol "CDIS."

                                 LEGAL MATTERS

     The validity of the Common Stock offered hereby will be passed upon for the
Company and the Selling Shareholders by Robins, Kaplan, Miller & Ciresi L.L.P.,

                    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 subsidiary as of December 31,
1996 and 1995, and the related consolidated statements of operations,
shareholders' equity and cash flows for the three years in the period ended
December 31, 1996. 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 subsidiary as of December 31, 1996 and 1995, and the
results of their operations and their cash flows for the three years in the
period ended December 31, 1996, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  ORGANIZATION:

     Cal Dive International, Inc. (Cal Dive or the Company), headquartered in
Houston, Texas, owns, staffs and operates eight marine construction vessels and
a derrick barge in the Gulf of Mexico. The Company provides a full range of
services to offshore oil and gas exploration and production and pipeline
companies, including underwater construction, maintenance and repair of
pipelines and platforms, and salvage operations. The Company was purchased for
approximately $10.7 million by a group of investors including current management
and key employees in a transaction which was effective July 27, 1990. This
transaction was accounted for using the purchase method of accounting.

     In September 1992, Cal Dive formed a wholly owned subsidiary, Energy
Resource Technology, Inc. (ERT), to purchase producing offshore oil and gas
properties which are in the later stages of their economic lives. ERT is a fully
bonded offshore operator and, in conjunction with the acquisition of properties,
assumes the responsibility to abandon the property in full compliance with all
governmental regulations.

     During 1995, First Reserve Corporation, on behalf of certain of the
investment funds it manages, acquired a 50 percent ownership position in the
Company by purchasing shares held by the employees and treasury shares held by
the Company (see Note 9).

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  PRINCIPLES OF CONSOLIDATION

     The accompanying consolidated financial statements include the accounts of
the Company and its subsidiary. All significant intercompany accounts and
transactions have been eliminated.

  PROPERTY AND EQUIPMENT

     Property and equipment are recorded at cost. Depreciation is provided
primarily on the straight-line method over the estimated useful lives of the
assets.

     ERT offshore property acquisitions are recorded at the value exchanged at
closing together with an estimate of its proportionate share of the
decommissioning liability assumed in the purchase based upon its working
interest ownership percentage. These costs, together with any associated capital
expenditures, are then amortized on a unit-of-production basis (UOP) based on
the estimated remaining oil and gas reserves.

     The following is a summary of the components of property and equipment:

     The cost of repairs and maintenance of vessels and equipment is charged to
operations as incurred, while the cost of improvements is capitalized.
Drydocking costs (exclusive of the cost of new steel and new equipment added to
a vessel) are also charged to operations as incurred. Total repair and
maintenance charges were $3,655,000, $2,368,000 and $1,518,000 for the years
ended December 31, 1996, 1995 and 1994, respectively. Upon the disposition of
property and equipment,

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
the related cost and accumulated depreciation accounts are relieved, and the
resulting gain or loss is included in other income (expense).

     In March 1995, Statement of Financial Accounting Standards (SFAS) No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
to Be Disposed Of," was issued. SFAS No. 121, which becomes effective for
fiscal years beginning after December 15, 1995, requires that certain long-lived
assets be reviewed for impairment whenever events indicate that the carrying
amount of an asset may not be recoverable and that an impairment loss be
recognized under certain circumstances in the amount by which the carrying value
exceeds the fair value of the asset. The Company adopted SFAS No. 121 in January
1996, as required, and the adoption had no effect on the Company's results of
operations or financial position.

  USE OF ESTIMATES

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

  REVENUE RECOGNITION

     The Company earns the majority of its service revenues during the summer
and fall months. Revenues are derived from billings under contracts (which are
typically of short duration) that provide for either lump-sum turnkey charges or
specific time, material and equipment charges which are billed in accordance
with the terms of such contracts. The Company recognizes revenue as it is earned
at estimated collectible amounts. Revenue on significant turnkey contracts is
recognized on the percentage-of-completion method based on the ratio of costs
incurred to total estimated costs at completion. Contract price and cost
estimates are reviewed periodically as work progresses and adjustments are
reflected in the period in which such estimates are revised. Provisions for
estimated losses on such contracts are made in the period such losses are
determined. Unbilled revenue represents revenue attributable to work completed
prior to year-end which has not yet been invoiced and work in process at the
balance sheet date which will be billed at the conclusion of the project. All
amounts included in unbilled revenue at December 31, 1996 and 1995, are expected
to be billed and collected within one year.

  MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK

     The market for the Company's services is the offshore oil and gas industry,
and the Company's customers consist primarily of major, well-established oil and
pipeline companies and independent oil and gas producers. The Company performs
ongoing credit evaluations of its customers and provides allowances for possible
credit losses when necessary; however, such losses have historically been
insignificant.

     Two customers which represented 26 percent and 10 percent, respectively, of
1994 revenues merged during 1995 and accounted for 21 percent and 24 percent of
consolidated revenues in the years 1995 and 1996, respectively.

  INCOME TAXES

     Deferred taxes are recognized for revenues and expenses reported in
different years for financial statement purposes and income tax purposes in
accordance with SFAS No. 109, "Accounting for Income Taxes." The statement
requires, among other things, the use of the liability

                                       F-8

                  CAL DIVE INTERNATIONAL, INC., AND SUBSIDIARY
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
method of computing deferred income taxes. The liability method is based on the
amount of current and future taxes payable using tax rates and laws in effect at
the balance sheet date.

  STATEMENT OF CASH FLOW INFORMATION

     The cash flow provided (used) by the various components of assets and
liabilities, excluding cash and cash equivalents and the effects of investing
and financing activities, is as follows:

</TABLE>
     The Company defines cash and cash equivalents as cash and all highly liquid
financial instruments with original maturities of less than three months. During
the years ended December 31, 1996, 1995 and 1994, the Company's cash payments
for interest were approximately $1,069,000, $526,000 and $559,000, respectively,
and cash payments for federal income taxes were approximately $2,200,000,
$663,000 and $1,633,000, respectively. In connection with 1996 and 1995 offshore
property acquisitions, ERT assumed net abandonment liabilities estimated at
approximately $1,200,000 and $3,800,000, respectively (see Note 3).

     The Company follows SFAS No. 115, "Accounting for Certain Investments in
Debt and Equity Securities." Under SFAS No. 115, debt securities, including
treasury bills and notes, that the Company has both the intent and ability to
hold to maturity, are carried at amortized cost and are included in cash
deposits restricted for salvage operations in the accompanying consolidated
balance sheets. As all of these securities as of December 31, 1996, are U.S.
Treasury securities and notes, the majority of which mature beyond one year, the
Company believes the recorded balance of these securities approximates their
fair market value.

  RECLASSIFICATIONS

     Certain reclassifications were made to previously reported amounts in the
consolidated financial statements and notes to make them consistent with the
current presentation format.

3.  OFFSHORE PROPERTY ACQUISITIONS:

     In 1992 and 1994, ERT acquired a 100 percent net working interest in three
offshore properties for value exchanged and for ERT assuming the liability to
plug the wells, abandon the platform and remediate the site. Upon depletion
during 1994, the property purchased in 1992 was salvaged and abandoned in full
compliance with all regulatory requirements and included a transaction
structured as a Section 1031 "Like Kind" exchange for tax purposes.
Accordingly, the cash received ($508,000) plus accrued interest at December 31,
1994, was restricted and used for the acquisition of ERT properties during 1995.
During 1995, net working interests of 50 percent to 100 percent in seven
offshore blocks were acquired in exchange for cash of $1,780,000 and ERT
assuming the related abandonment liabilities. The 1996 property acquisitions
included net working

                                       F-9
<PAGE>
                  CAL DIVE INTERNATIONAL, INC., AND SUBSIDIARY
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
interests of 33 percent to 100 percent in four offshore blocks which were
acquired for cash of $3,600,000 and assumption of a pro rata share of the
decommissioning liability.

     ERT production activities are regulated by the federal government and
require a significant amount of third-party involvement, such as refinery
processing and pipeline transportation. The Company records revenue from its
offshore properties net of royalties paid to the Minerals Management Service.
Royalty fees paid totaled approximately $1,996,000, $875,000 and $460,000 for
the years ended 1996, 1995 and 1994, respectively. In accordance with federal
regulations that require operators in the Gulf of Mexico to post an areawide
bond of $3,000,000, cash deposits restricted for salvage operations include U.S.
Treasury bonds of $3,300,000 at December 31, 1996 and 1995, respectively (see
Note 2). In addition, the terms of certain of the 1992 and 1993 purchase and
sale agreements require that ERT deposit a portion of a property's net
production revenue into an interest-bearing escrow account until such time as a
specified level of funding has been set aside for salvaging and abandoning the
properties. As of December 31, 1996, such deposits totaled $1,900,000 and are
included in cash deposits restricted for salvage operations in the accompanying
balance sheet.

4.  ACCRUED LIABILITIES:

     Accrued liabilities consisted of the following:

                                            1996            1995

5.  REVOLVING CREDIT FACILITY:

     During 1995, the Company entered into a $30 million revolving credit
facility, maturing in May 2000, which is secured by property and equipment and
trade receivables. At the Company's option, interest is at a rate equal to 2.00
percent above a Eurodollar base rate (2.25 on borrowings less than $10 million)
or .5 percent above prime. Pursuant to these terms, borrowings at December 31,
1996, included $22 million at 7.37 percent (Eurodollar option) and $3 million at
8.75 percent. 1995 year-end borrowings were comprised of $4.5 million at 8.2
percent (Eurodollar option) and $800,000 at 9 percent. The Company drew upon the
revolving credit facility throughout 1996 and for a total of 238 days during
1995 with maximum borrowings of $25,000,000 and $8,000,000 in those years. At
March 7, 1997, $5.9 million was available under the revolving credit facility.

     Under this credit facility, letters of credit (LOC) are also available
which the Company typically uses if performance bonds are required and, in
certain cases, in lieu of purchasing U.S. Treasury bonds in conjunction with ERT
property acquisitions. At December 31, 1996, LOC totaling $4.25 million were
outstanding pursuant to these terms.

     The revolving credit facility contains, among other restrictions, financial
covenants which require the Company to (a) maintain income from operations at
specified levels, (b) limit leverage, as defined, to no more than a specified
ratio of net worth, (c) maintain certain interest coverage and debt service
ratios, as defined, and (d) maintain a minimum ratio of current assets to
current liabilities. The Company was in compliance with, or obtained waivers of
default from the bank for, these debt covenants at December 31, 1996.

     Borrowings during 1994 bore interest at prime plus 1 percent pursuant to a
revolving credit and term loan facility in place during those years. During
1994, the Company drew upon this facility for 151 days with a maximum borrowing
of $2,377,000. The amount outstanding on the term loan was converted to the new
revolving credit facility in May of 1995.

6.  FEDERAL INCOME TAXES:

     Federal income taxes have been provided based on the statutory rate of 34
percent adjusted for items which are allowed as deductions for federal income
tax reporting purposes, but not for book purposes. The primary differences
between the statutory rate and the Company's effective rate are as follows:

                                             1996         1995         1994

     Components of the provision for income taxes reflected in the statements of
operations consist of the following:

                             1996            1995            1994

     Deferred income taxes result from those transactions which affect financial
and taxable income in different years. The nature of these transactions and the
income tax effect of each as of December 31, 1996 and 1995, is as follows:

                                               1996            1995

     Internal Revenue Service (IRS) conducted an examination of the Company's
federal income tax returns for the period from inception (July 27, 1990) through
December 1991. In connection with this examination, the IRS proposed additional
taxes due based upon its interpretation of the recording of certain transactions
at the date the Company was acquired. This matter was settled during 1996 with
insignificant impact upon the Company's consolidated financial position or
results of operations.

7.  COMMITMENTS AND CONTINGENCIES:

  LEASE COMMITMENTS

     The Company occupies several facilities under noncancelable operating
leases, with the more significant leases expiring in 1997. Future minimum
rentals under these leases are $223,000 at December 31, 1996, with $164,000 in
1997 and the balance thereafter. Total rental expense under operating leases was
$262,000, $240,000 and $226,000 for the years ended December 31, 1996, 1995 and
1994, respectively.

  INSURANCE

     The Company carries hull protection on vessels, indemnity insurance and a
general umbrella policy. All onshore employees are covered by workers'
compensation, and all offshore employees, including divers and tenders, are
covered by Jones Act employee coverage, the maritime equivalent of workers'
compensation. The Company is exposed to deductible limits on its insurance
policies, which vary from $5,000 to a maximum of $50,000 per accident
occurrence. Effective August 1, 1992, the Company adopted a self-insured (within
specified limits) medical and health benefits program for its employees whereby
the Company is exposed to a maximum of $15,000 per claim.

  LITIGATION

     Various actions and claims are pending against the Company which management
believes are covered by insurance. In the opinion of management, the ultimate
liability to the Company, if any, which may result from these actions and claims
will not materially affect the Company's consolidated financial position,
results of operations or cash flows.

8.  EMPLOYEE BENEFIT PLANS:

  DEFINED CONTRIBUTION PLAN

     The Company sponsors a defined contribution 401(k) retirement plan covering
substantially all of its employees. The Company's contributions and cost are
determined annually as 50 percent of each employee's contribution up to 5
percent of the employee's salary. The Company's costs related to this plan
totaled $197,000, $168,000 and $150,000 for the years ended December 31, 1996,
1995 and 1994, respectively.

  INCENTIVE AND STOCK OPTION PLAN

     During 1995, the board of directors and shareholders approved the 1995
Long-Term Incentive Plan (the Incentive Plan). Under the Incentive Plan, a total
of 600,000 shares of common stock is available for awards to key executives and
selected employees who are likely to make a significant positive impact on the
reported net income of the Company. The Incentive Plan is administered by a
committee which determines, subject to board approval, the type of award to be
made to each participant and sets forth in the related award agreement the
terms, conditions and limitations applicable to each award. The committee may
grant stock options, stock appreciation rights, or stock and cash awards.

     The stock option plan is accounted for using APB Opinion No. 25, and
therefore no compensation expense is recorded. If SFAS Statement No. 123 had
been used for the accounting of these plans, the Company's pro forma net income
for 1996, 1995 and 1994 would have been $8,330,000, $2,607,000 and $4,034,000,
respectively, and the Company's pro forma earnings per share would have been
$.74, $.24 and $.46, respectively. These pro forma results exclude

</TABLE>
     All of the options outstanding at December 31, 1996, have an exercise price
of $4.50 and a weighted average remaining contractual life of 3.9 years.

     The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option pricing model with the following weighted average
assumptions used for grants in 1996 and 1995: risk-free interest rates of 5.9
percent; expected dividend yields of 0 percent; expected lives of five years;
and expected volatility of 0 percent.

9.  COMMON STOCK:

     During 1991, certain key employees were granted options to purchase 60,000
shares at a price of $.75 per share. In addition, a member of the management
group sold 1,000,000 shares to the Company during 1992 at a price established by
the board of directors and was granted an option to repurchase 500,000 of those
shares at the same price. All of these options were exercised in 1995 in
conjunction with the sale of stock to First Reserve Corporation as discussed
below.

     During 1995, the board of directors and shareholders approved an amendment
to the Articles of Incorporation increasing the number of authorized shares from
2,000,000 to 20,000,000. In connection with this measure, a 10-for-1 stock split
was also approved. Accordingly, all of the share and per share information
included in the financial statements and notes thereto has been restated
retroactively to reflect the 10-for-1 stock split.

     During 1995, First Reserve Corporation, on behalf of certain of the
investment funds it manages, acquired a 50 percent ownership position in the
Company by purchasing 3,329,780 shares held by employees and 2,219,850 treasury
shares held by the Company, increasing shareholders' equity by $10,000,000.

     In conjunction with this transaction, the Company entered into an Amended
and Restated Shareholders' Agreement which increased the board of directors from
five to seven members and which provides that First Reserve Corporation can
cause a sale of the Company in certain circumstances (as defined) subsequent to
December 31, 1999.

  ESTIMATED QUANTITIES OF PROVED OIL AND GAS RESERVES

     Proved oil and gas reserve quantities are based on estimates prepared by
Company engineers in accordance with guidelines established by the Securities
and Exchange Commission. The Company's estimates of reserves at December 31,
1996, have been reviewed by Miller and Lents, Ltd., independent petroleum
engineers. All of the Company's reserves are located in the United States.
Proved reserves cannot be measured exactly because the estimation of reserves
involves numerous judgmental determinations. Accordingly, reserve estimates must
be continually revised as a result of new information obtained from drilling and
production history, new geological and geophysical data and changes in economic
conditions.

14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Minnesota Statutes Section 302A.521 provides that a corporation organized
under Minnesota law shall indemnify any director, officer, employee or agent of
the corporation made or threatened to be made a party to a proceeding, by reason
of the former or present official capacity (as defined) of the person, against
judgments, penalties, fines, settlements and reasonable expenses incurred by the
person in connection with the proceedings if certain statutory standards are
met. "Proceeding" means a threatened, pending or completed civil, criminal,
administrative, arbitration or investigative proceeding, including one by or in
the right of the corporation. Section 302A.521 contains detailed terms regarding
such rights of indemnification and reference is made thereto for a complete
statement of such indemnification rights.

     Reference is made to the Underwriting Agreement filed as Exhibit 1 to this
Registration Statement for a description of indemnification arrangements related
to this Offering.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Act") may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that, in the opinion of the
Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

15.  RECENT SALES OF UNREGISTERED SECURITIES.

     During the last three years, the Company has sold the following securities
(as adjusted for a     -for-1 reverse stock split effective                  ,
1997) that were not registered under the Act.

     1.  On January 12, 1995, the Company issued an aggregate of 3,795,393
shares of Common Stock to First Reserve Secured Energy Assets, First Reserve
Fund V, First Reserve Fund V-2 and First Reserve Fund VI at a price of $4.50 per
share for an aggregate consideration of $10 million.

     2.  From November 1995 through May 1996, pursuant to the provisions of the
1995 Long Term Incentive Plan, the Company granted options to purchase an
aggregate of 476,500 shares of Common Stock at an exercise price of $4.50 per
share to certain employees, including officers and directors.

     3.  In January 1995, the Company granted options to purchase 15,046 shares
of Common Stock at an exercise price of $4.50 per share to Gerald G. Hage.

     4.  In April 1997, the Company granted options to employees to purchase an
aggregate of 435,000 shares at an exercise price of $9.50 per share.

     5.  On April 11, 1997, the Company issued an aggregate of 528,541 shares of
Common Stock to Coflexip at a per share price equal to $9.46 per share in
consideration for the purchase of certain assets valued at an aggregate of $5
millon and in entering into a Business Cooperation Agreement pursuant to which
the Company and Coflexip intend to form a joint venture for combined services on
Gulf of Mexico projects.

     No underwriting commissions or discounts were paid with respect to the
sales of unregistered securities described herein.

     Except as otherwise noted, all of the above sales were made in reliance on
Section 4(2) of the Act for transactions not involving a public offering. With
regard to the reliance by the Company upon such exemption for registration,
certain inquiries were made by the Company to establish that such sales
qualified for such exemption from the registration requirements. In particular,
the Company confirmed that (i) each purchaser provided the Company with written
assurance of investment intent, and the certificates for the shares sold
accordingly bear restrictive legends and (ii) sales were made to a limited
number of persons.

17.  UNDERTAKINGS.

     (a)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933, as amended (the "Act") may be permitted to directors,
officers and controlling persons of the Registrant pursuant to the foregoing
provisions, or otherwise, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

     (b)  The Registrant hereby undertakes to provide of the Underwriter at the
closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriter to
permit prompt delivery to each purchaser.

     (c)  The undersigned registrant hereby undertakes that:

     i.  For purposes of determining liability under the Securities Act of 1933,
the information omitted from the form of prospectus filed as part of a
registration statement filed pursuant to Rule 430A and contained in the form of
a prospectus filed by the registrant pursuant to Rule 424(b)(1) or Rule 497(h)
under the Securities Act of 1933 shall be deemed to be part of the Registration
Statement as of the time it was declared effective.

     ii.  For the purpose of determining liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus shall be
deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

Securities sold to the Underwriters pursuant to this paragraph being sold on a

purchase the Option Securities may be exercised by your giving 48 hours' prior
written or telephonic notice (subsequently confirmed in writing) to the Company
of your determination to purchase all or a portion of the Option Securities.
Such notice may be given at any time within a period of 30 days following the

                  Securities for sale upon the terms and conditions set forth in

                  13)      The Registration Statement has become effective
                  under the Act, the Prospectus has been filed in accordance
                  with Rule 424(b) of the Rules and Regulations of the
                  Commission under the Act, including the applicable time
                  periods set forth therein, or such filing is not required and,
                  to the best knowledge of such counsel, no stop order
                  suspending the effectiveness of the Registration Statement has
                  been issued and no proceedings for that purpose have been
                  instituted or are pending or threatened under the Act, and the
                  Registration Statement, the Prospectus and each amendment or
                  supplement thereto, as of their respective effective or issue
                  dates, complied as to form in all material respects with the
                  requirements of the Act and the Rules and Regulations
                  thereunder; it being understood that such counsel need express
                  no opinion as to the financial statements and schedules or
                  other financial data contained in the Registration Statement
                  or the Prospectus.

                  Such counsel shall also state that nothing has come to such
            counsel's attention that would lead such counsel to believe that
            either the Registration Statement or any amendment or supplement
            thereto, at the time such Registration Statement or amendment or
            supplement became effective, or the Prospectus or any amendment or
            supplement thereto, as of its date and as of the Time of Delivery,
            contains or contained any untrue statement of material fact or
            omitted or omits to state a material fact required to be stated
            therein or necessary to make the statements therein, in light of the
            circumstances under which they were made, not misleading.

                  In rendering their opinions set forth in Section 7(d) above,
            such counsel may rely, to the extent deemed advisable by such
            counsel, (a) as to factual matters, upon certificates of public
            officials and officers of the Company, and (b) as to the laws of

                        be furnished to you at the Time of Delivery certificates
                        signed by the chief executive officer and the chief

                        of options granted thereunder or to any gift of Common
                        Stock or any private sale of Common Stock not made on

                        that agrees in writing for the benefit of the

                        (xiii)The Company shall have delivered to you
                        evidence that the Securities have been authorized for
                        quotation on the Nasdaq National Market as of the

            viii.  The Company will indemnify and hold harmless each
            Underwriter against any losses, claims, damages or liabilities,
            joint or several, to which such Underwriter may become subject,

            or liabilities (or actions in respect thereof) arise out of or are
            based upon (i) any untrue statement or alleged untrue statement of a
            material fact contained in any Preliminary Prospectus, the
            Registration Statement or the Prospectus, or any amendment or
            supplement thereto, or in any Blue Sky application or other document
            executed by the Company specifically for that purpose or based upon
            written information furnished by the Company filed in any state or
            other jurisdiction in order to qualify any or all the Securities
            under the security laws thereof or filed with the Commission or any
            securities association or securities exchange (each, an
            "Application"), or the omission or alleged omission to state therein
            a material fact required to be stated therein or necessary to make
            the statements made therein not misleading, or (ii) any untrue
            statement or alleged untrue statement made by the Company in Section
            1 of this Agreement, or (iii) the employment by the Company of any
            device, scheme or artifice to defraud, or the engaging by the
            Company in any act, practice or course of business which operates or
            would operate as a fraud or deceit, or any conspiracy with respect
            thereto, in which the Company shall participate, in connection with

            any of the Securities, and will reimburse each Underwriter for any
            legal or other expenses reasonably incurred by such Underwriter in
            connection with investigating, preparing to defend, defending or
            appearing as a third-party witness in connection with any such
            action or claim; PROVIDED, HOWEVER, that the Company shall not be
            liable in any such case to the extent that any such loss, claim,
            damage or liability arises out of or is based upon an untrue
            statement or alleged untrue statement or omission or alleged
            omission relating to an Underwriter made in any Preliminary
            Prospectus, the Registration Statement, the Prospectus or such
            amendment or supplement or any Application in reliance upon and in
            conformity with written information furnished to the Company by such
            Underwriter through you expressly for use therein.

                  (i)   In addition to any obligations of the Company under
                  Section 8(a), the Company agrees that it shall perform its
                  indemnification obligations under Section 8(a) (as modified by
                  the last paragraph of this Section 8(b)) with respect to
                  counsel fees and expenses and other expenses reasonably
                  incurred by making payments within 45 days to the Underwriter
                  in the amount of the statements of the Underwriter's counsel
                  or other statements which shall be forwarded by the
                  Underwriter, and that they shall make such payments
                  notwithstanding the absence of a judicial determination as to
                  the propriety and enforceability of the obligation to
                  reimburse the Underwriters for such expenses and the
                  possibility that such payments might later be held to have
                  been improper by a court and a court orders return of such
                  payments.

            The indemnity agreement in Section 8(a) shall be in addition to any
      liability which the Company may otherwise have and shall extend upon the
      same terms and conditions to each person, if any, who controls any
      Underwriter within the meaning of the Act or the Exchange Act.

                  (ii) Each Selling Shareholder will indemnify and hold
                  harmless each Underwriter or the Company, as the case may be,
                  against any losses, claims, damages or liabilities, joint or
                  several, to which such Underwriter or the Company, as the case
                  may be, may become subject, under the Act or otherwise,
                  insofar as such losses, claims, damages or liabilities (or
                  actions in respect thereof) arise out of or are based upon

                  (i) any untrue statement or alleged untrue statement of a
                  material fact contained in any Preliminary Prospectus, the
                  Registration Statement or the Prospectus, or any amendment or
                  supplement thereto, or in any Blue Sky application or other
                  document executed by the Company specifically for that purpose
                  or based upon written information furnished to the Company by
                  the Selling Shareholder filed in any state or other
                  jurisdiction in order to qualify any or all the Securities
                  under the security laws thereof or filed with the Commission
                  or any securities association or securities exchange (each, an
                  "Application"), or the omission or alleged omission to state
                  therein a material fact required to be stated therein or
                  necessary to make the statements made therein not misleading
                  in each case to the extent, but only to the extent, that such
                  untrue statement or alleged untrue statement or omission was
                  made in reliance upon and in conformity with written
                  information furnished to the Company by such Selling
                  Shareholder specifically for use therein or (ii) any untrue
                  statement or alleged untrue statement made by the Selling
                  Shareholder in Section 1.A of this Agreement; PROVIDED,
                  HOWEVER, that the Selling Shareholder shall not be liable in
                  any such case to the extent that any such loss, claim, damage
                  or liability arises out of or is based upon an untrue
                  statement or alleged untrue statement or omission or alleged
                  omission relating to an Underwriter made in any Preliminary
                  Prospectus, the Registration Statement, the Prospectus or such
                  amendment or supplement or any Application in reliance upon
                  and in conformity with written information furnished to the
                  Company by such Underwriter through you expressly for use
                  therein. In addition, in no event shall the liability of any
                  Selling Shareholder for indemnification in this Section 8(c)
                  exceed the proceeds received by such Selling Shareholder in
                  the Offering.

                  (iii)In addition to any obligations of each of the
                  Selling Shareholders under Section 8(c), each of the Selling
                  Shareholders agrees that it shall perform its indemnification
                  obligations under Section 8(c) (as

                  respect to counsel fees and expenses and other expenses
                  reasonably incurred by making payments within 45 days to the
                  Underwriter in the amount of the statements of the
                  Underwriter's counsel or other statements which shall be

                  payments notwithstanding the absence of a judicial
                  determination as to the propriety and enforceability of the
                  obligation to reimburse the Underwriters for such expenses and

                  been improper by a court and a court orders return of such
                  payments.

            The indemnity agreement in Section 8(c) shall be in addition to any
      liability which the Company may otherwise have and shall extend upon the
      same terms and conditions to each person, if any, who controls any
      Underwriter within the meaning of the Act or the Exchange Act.

                  (iv) Each Underwriter will indemnify and hold harmless
                  the Company or the Selling Shareholders, as the case may be,
                  against any losses, claims, damages or liabilities to which
                  the Company or any of the Selling Shareholders may become
                  subject, under the Act or otherwise, insofar as such losses,
                  claims, damages or liabilities (or actions in respect thereof)
                  arise out of or are based upon an untrue statement or alleged
                  untrue statement of a material fact contained in any
                  Preliminary Prospectus, the Registration Statement or the
                  Prospectus, or any amendment or supplement thereto, or any
                  Application, or arise out of or are based upon the omission or
                  alleged omission to state therein a material fact required to
                  be stated therein or necessary to make the statements therein
                  not misleading, in each case to the extent, but only to the
                  extent, that such untrue statement or alleged untrue statement
                  or omission or alleged omission was made in any Preliminary

                  relating to such Underwriter through you

                  expressly for use therein, and will reimburse the Company or
                  the Selling Shareholder for any legal or other expenses
                  reasonably incurred by the Company or the Selling Shareholder
                  in connection with investigating or defending any such action
                  or claim.

            The indemnity agreement in this Section 8(e) shall be in addition to
      any liability which the respective Underwriters may otherwise have and
      shall extend, upon the same terms and conditions, to each officer and
      director of the Company and to each person, if any, who controls the
      Company within the meaning of the Act or the Exchange Act.

                  (v)  Promptly after receipt by an indemnified party under
                  Section 8(a), 8(c) or 8(e) of notice of the commencement of
                  any action (including any governmental investigation), such
                  indemnified party shall, if a claim in respect thereof is to
                  be made against the indemnifying party under such subsection,
                  notify the indemnifying party in writing of the commencement
                  thereof; but the omission so to notify the indemnifying party
                  shall not relieve it from any liability which it may have to
                  any indemnified party under Section 8(a), 8(c) or 8(e) except
                  to the extent it was unaware of such action and has been
                  prejudiced in any material respect by such failure or from any
                  liability which it may have to any indemnified party otherwise
                  than under such Section 8(a), 8(c) or 8(e). In case any such
                  action shall be brought against any indemnified party and it
                  shall notify the indemnifying party of the commencement
                  thereof, the indemnifying party shall be entitled to
                  participate therein and, to the extent that it shall wish,
                  jointly with any other indemnifying party similarly notified,
                  to assume the defense thereof, with counsel satisfactory to
                  such indemnified party, and after notice from the indemnifying
                  party to such indemnified party of its election so to assume
                  the defense thereof, the indemnifying party shall not be
                  liable to such indemnified party under such subsection for any
                  legal or other expenses subsequently incurred by such
                  indemnified party in connection with the defense thereof other
                  than reasonable costs of investigation. If, however, (i) the
                  indemnifying party has authorized the employment of counsel
                  for the indemnified party

                  at the expense of the indemnifying party or (ii) an
                  indemnified party shall have reasonably concluded that
                  representation of such indemnified party and the indemnifying
                  party by the same counsel would be inappropriate under
                  applicable standards of professional conduct due to actual or
                  potential differing interests between them and the indemnified
                  party so notifies the indemnifying party, then the indemnified
                  party shall be entitled to employ counsel different from
                  counsel for the indemnifying party at the expense of the
                  indemnifying party and the indemnifying party shall not have
                  the right to assume the defense of such indemnified party. In
                  no event shall the indemnifying parties be liable for fees and
                  expenses of more than one counsel (in addition to local
                  counsel) for all indemnified parties in connection with any
                  one action or separate but similar or related actions in the
                  same jurisdiction arising out of the same set of allegations
                  or circumstances. The counsel with respect to which fees and
                  expenses shall be so reimbursed shall be designated in writing
                  by Schroder Wertheim in the case of parties indemnified
                  pursuant to Section 8(a) and 8(c) and by the Company and the
                  Selling Shareholders in the case of parties indemnified
                  pursuant to Section 8(e).

            No indemnifying party shall, without the prior written consent of
      the indemnified party, effect any settlement of any pending or threatened
      proceeding in respect of which any indemnified party is or could have been
      a party and indemnity could have been sought hereunder by such indemnified
      party, unless such settlement includes an unconditional release of such

      of such proceeding.

                  (vi) In order to provide for just and equitable
                  contribution under the Act in any case in which (i) any
                  Underwriter (or any person who controls any Underwriter within
                  the meaning of the Act or the Exchange Act) makes claim for
                  indemnification pursuant to Section 8(a) or 8(c) hereof, but
                  is judicially determined (by the entry of a final judgment or
                  decree by a court of competent jurisdiction and the expiration
                  of time to appeal or the denial of the last right of appeal)
                  that such indemnification may not be

                  enforced in such case notwithstanding the fact that Section
                  8(a) or 8(c) provides for indemnification in such case or (ii)
                  contribution under the Act may be required on the part of any
                  Underwriter or any such controlling person in circumstances
                  for which indemnification is provided under Section 8(e),
                  then, and in each such case, each indemnifying party shall
                  contribute to the aggregate losses, claims, damages or
                  liabilities to which they may be subject as an indemnifying
                  party hereunder (after contribution from others) in such
                  proportion as is appropriate to reflect the relative benefits
                  received by the Company or any of the Selling Shareholders on
                  the one hand and the Underwriters on the other from the
                  offering of the Securities. If, however, the allocation
                  provided by the immediately preceding sentence is not
                  permitted by applicable law or if the indemnified party failed
                  to give the notice required under Section 8(d) above, then
                  each indemnifying party shall contribute to such amount paid
                  or payable by such indemnified party in such proportion as is
                  appropriate to reflect not only such relative benefits but
                  also the relative fault of the Company on the one hand and the
                  Underwriters on the other in connection with the statements or
                  omissions which resulted in such losses, claims, damages or
                  liabilities (or actions in respect thereof), as well as any
                  other relevant equitable considerations. The relative benefits
                  received by the Company or any of the Selling Shareholders on
                  the one hand and the Underwriters on the other shall be deemed
                  to be in the same proportion as the total net proceeds from
                  the offering of the Securities purchased under this Agreement
                  (before deducting expenses) received by the Company or any of
                  the Selling Shareholders bear to the total underwriting
                  discounts and commissions received by the Underwriters with
                  respect to the Securities purchased under this Agreement, in
                  each case as set forth in the table on the cover page of the
                  Prospectus. The relative fault shall be determined by
                  reference to, among other things, whether the untrue or
                  alleged untrue statement of a material fact or the omission or
                  alleged omission to state a material fact relates to
                  information supplied by the Company or any

<PAGE>
                  of the Selling Shareholders on the one hand or the
                  Underwriters on the other and the parties' relative intent,
                  knowledge, access to information and opportunity to correct or
                  prevent such statement or omission. The Company, each of the
                  Selling Shareholders and the Underwriters agree that it would
                  not be just and equitable if contributions pursuant to this
                  Section 8(g) were determined by PRO RATA allocation (even if
                  the Underwriters were treated as one entity for such purpose)
                  or by any other method of allocation which does not take
                  account of the equitable considerations referred to above in
                  this Section 8(g). The amount paid or payable by an
                  indemnified party as a result of the losses, claims, damages
                  or liabilities (or actions in respect thereof) referred to
                  above in this Section 8(g) shall be deemed to include any
                  legal or other expenses reasonably incurred by such
                  indemnified party in connection with investigating or
                  defending any such action or claim. Notwithstanding the
                  provisions of this Section 8(g), no Underwriter shall be
                  required to contribute any amount in excess of the amount by
                  which the total price at which the Securities underwritten by
                  it and distributed to the public were offered to the public
                  exceeds the amount of any damages which such Underwriter has
                  otherwise been required to pay by reason of such untrue or
                  alleged untrue statement or omission or alleged omission and
                  no Selling Shareholder shall be required to contribute any
                  amount in excess of the proceeds received by such Selling
                  Shareholder in the Offering. No person guilty of a fraudulent
                  misrepresentation (within the meaning of Section 11(f) of the
                  Act) shall be entitled to contribution from any person who was
                  not guilty of such fraudulent misrepresentation. The
                  Underwriters' obligations in this Section 8(e) to contribute
                  are several in proportion to their respective underwriting
                  obligations and not joint.

                  (vii)Promptly after receipt by any party to this
                  Agreement of notice of the commencement of any action, suit or
                  proceeding, such party will, if a claim for contribution in

                  against another party (the "contributing party"), notify the
                  contributing party of the commencement thereof; but the
                  omission so to notify the contributing party will not relieve
                  it from any liability which it may have to any other party for
                  contribution under the Act except to the extent it was unaware
                  of such action and has been prejudiced in any material respect
                  by such failure or from any liability which it may have to any
                  other party other than for contribution under the Act. In case
                  any such action, suit or proceeding is brought against any
                  party, and such party notifies a contributing party of the
                  commencement thereof, the contributing party will be entitled
                  to participate therein with the notifying party and any other
                  contributing party similarly notified.

      ix.    If any Underwriter shall default in its obligation to purchase
      the Firm Securities which it has agreed to purchase hereunder, you may in
      your discretion arrange for you or another party or other parties to
      purchase such Firm Securities on the terms contained herein. If the
      aggregate number of Firm Securities as to which Underwriters default is
      more than one-eleventh of the aggregate number of all the Firm Securities
      and within 36 hours after such default by any Underwriter you do not
      arrange for the purchase of such Firm Securities, then the Company shall
      be entitled to a further period of 36 hours within which to procure
      another party or other parties satisfactory to you to purchase such Firm
      Securities on such terms. In the event that, within the respective
      prescribed periods, you notify the Company that you have so arranged for
      the purchase of such Firm Securities, or the Company notifies you that it
      has so arranged for the purchase of such Firm Securities, you or the
      Company shall have the right to postpone the Time of Delivery for a period
      of not more than seven days, in order to effect whatever changes may
      thereby be made necessary in the Registration Statement or the Prospectus
      or in any other documents or arrangements, and the Company agrees to file
      promptly any amendments to the Registration Statement or the Prospectus
      which in your opinion may thereby be made necessary. The term
      "Underwriter" as used in this Agreement shall include any person
      substituted under this Section with like effect as if such person had
      originally been a party to this Agreement with respect to such Firm
      Securities.

            (i)    If, after giving effect to any arrangements for the
            purchase of the Firm Securities of such defaulting Underwriter or
            Underwriters by you or the Company or both as provided in subsection
            (a) above, the

            aggregate number of such Firm Securities which remain unpurchased
            does not exceed one-eleventh of the aggregate number of all the Firm
            Securities, then the Company shall have the right to require each
            non-defaulting Underwriter to purchase the number of the Firm
            Securities which such Underwriter agreed to purchase hereunder and,
            in addition, to require each non-defaulting Underwriter to purchase
            its pro rata share (based on the number of Firm Securities which
            such Underwriter agreed to purchase hereunder) of the Firm
            Securities of such defaulting Underwriter or Underwriters for which
            such arrangements have not been made; but nothing shall relieve a
            defaulting Underwriter from liability for its default.

            (ii)   If, after giving effect to any arrangements for the
            purchase of the Firm Securities of a defaulting Underwriter or
            Underwriters by you or the Company as provided in subsection (a)
            above, the aggregate number of such Firm Securities which remain
            unpurchased exceeds one-eleventh of the aggregate number of all the
            Firm Securities, or if the Company shall not exercise the right
            described in subsection (b) above to require non-defaulting
            Underwriters to purchase Firm Securities of a defaulting Underwriter
            or Underwriters, then this Agreement shall thereupon terminate
            without liability on the part of any non- defaulting Underwriter or
            the Company, except for the expenses to be borne by the Company and
            the Underwriters as provided in Section 6 hereof and the indemnity
            agreement in Section 8 hereof; but nothing herein shall relieve a
            defaulting Underwriter from liability for its default.

      x.     The respective indemnities, agreements, representations,
      warranties and other statements of the Company, the Selling Shareholders
      and the several Underwriters, as set forth in this Agreement or made by or
      on behalf of them, respectively, pursuant to this Agreement, shall remain
      in full force and effect, regardless of any investigation (or any
      statement as to the results thereof) made by or on behalf of any
      Underwriter or any controlling person of any Underwriter, or the Company,
      or an officer or director or controlling person of the Company, or any
      Selling Shareholder, or an officer or director

      or controlling person of the Selling Shareholder, and shall survive
      delivery of and payment for the Securities.

      xi.    This Agreement shall become effective (a) if the Registration
      Statement has not heretofore become effective, at the earlier of 12:00
      Noon, New York City time, on the first full business day after the
      Registration Statement becomes effective, or at such time after the
      Registration Statement becomes effective as you may authorize the sale of
      the Securities to the public by Underwriters or other securities dealers,
      or (b) if the Registration Statement has heretofore become effective, at
      the earlier of 24 hours after the filing of the Prospectus with the
      Commission or at such time as you may authorize the sale of the Securities
      to the public by Underwriters or securities dealers, unless, prior to any
      such time you shall have received notice from the Company that it elects
      that this Agreement shall not become effective, or you, or through you
      such of the Underwriters as have agreed to purchase in the aggregate fifty
      percent or more of the Firm Securities hereunder, shall have given notice
      to the Company that you or such Underwriters elect that this Agreement
      shall not become effective; PROVIDED, HOWEVER, that the provisions of this
      Section and Section 6 and Section 8 hereof shall at all times be
      effective.

      If this Agreement shall be terminated pursuant to Section 9 hereof, or if
this Agreement, by election of you or the Underwriters, shall not become
effective pursuant to the provisions of this Section, the Company shall not then
be under any liability to any Underwriter except as provided in Section 6 and
Section 8 hereof, but if this Agreement becomes effective and is not so
terminated but the Securities are not delivered by or on behalf of the Company
as provided herein because the Company has been unable for any reason beyond its
control and not due to any default by it to comply with the terms and conditions
hereof, the Company will reimburse the Underwriters through you for all
out-of-pocket expenses approved in writing by you, including fees and
disbursements of counsel, reasonably incurred by the Underwriters in making
preparations for the purchase, sale and delivery of the Securities, but the
Company shall then be under no further liability to any Underwriter except as
provided in Section 6 and Section 8 hereof.

      xii.   The statements set forth in the last paragraph on the front
      cover page of the Prospectus, the paragraph on the inside front cover of
      the Prospectus containing stabilization language and the third and eighth
      paragraphs under the caption "Underwriting" in the Prospectus constitute
      the only information furnished by any Underwriter through the
      Representatives to the Company for purposes of Sections 1(b), 1(c) and 8
      hereof.

      xiii.  In all dealings hereunder, you shall act on behalf of each of
      the Underwriters, and the parties hereto shall be entitled to act and rely
      upon any statement, request, notice or agreement on behalf of any
      Underwriter made

otherwise specified in this Agreement, shall be in writing and, if to the

HOWEVER, that any notice to any Underwriter pursuant to Section 8(d) hereof

Underwriter at its address set forth in its Underwriters' Questionnaire, or
telex constituting such Questionnaire, which address will be supplied to the
Company by you upon request. Any such statements, requests, notices or
agreements shall take effect at the time of receipt thereof.

      xiv.   This Agreement shall be binding upon, and inure solely to the
      benefit of, the Underwriters, the Company, the Selling Shareholders and,
      to the extent provided in Section 8 and Section 10 hereof, the officers
      and directors of the Company and each person who controls the Company or
      any Underwriter, and their respective heirs, executors, administrators,
      successors and assigns, and no other person shall acquire or have any
      right under or by virtue of this Agreement. No purchaser of any of the
      Securities from any Underwriter shall be deemed a successor or assign by
      reason merely of such purchase.

      xv.    Time shall be of the essence of this Agreement. As used herein,
      the term "business day" shall mean any day when the Commission's office in
      Washington, D.C. is open for business.

      XVI.   THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS
      OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE CONFLICTS OF LAWS
      PRINCIPLES THEREOF.

      xvii.  This Agreement may be executed by any one or more of the
      parties hereto in any number of counterparts, each of which shall be
      deemed to be an original, but all such counterparts shall together
      constitute one and the same instrument.

                          CAL DIVE INTERNATIONAL, INC.

      I, Gerald G. Reuhl, the Chairman of Cal Dive International, Inc., a
Minnesota corporation, do hereby certify that by resolutions in lieu of a
special meeting of the shareholders of said Corporation, effective as of April

      RESOLVED:

      The Articles of Incorporation of this Corporation shall be amended and

                           "1997 AMENDED AND RESTATED
                            ARTICLES OF INCORPORATION
                                       OF
                          CAL DIVE INTERNATIONAL, INC."

                                   ARTICLE II

      The Corporation shall have general business purposes and shall have

<PAGE>
                                   ARTICLE V
                                    CAPITAL

      A. The total authorized capital stock of the Corporation is sixty million
(60,000,000) shares of Common Stock, without par value, and five million
(5,000,000) shares of Preferred Stock with $0.01 par value.

      B. Shares of Preferred Stock may be divided into and issued from time to
time in one or more series. In addition to, and not by way of limitation of, the
power granted to the Board of Directors of this Corporation by Minnesota
Statutes, Chapter 302A, the Board of Directors of the Corporation shall have the
power and authority to fix by resolution the preferences, limitations and
relative rights of the Preferred Stock of each series. The Board of Directors is
hereby authorized to fix and determine such variations in the designations,
preferences, and relative participating, optional or other special rights
(including, without limitation, special voting rights, preferential rights to
receive dividends or assets upon liquidation, rights of conversion into Common
Stock or other securities, redemption provisions or sinking fund provisions) as
between series and as between the Preferred Stock or any series thereof and the
Common Stock, and the qualifications, limitations or restrictions of such
rights, and the shares of Preferred Stock or any series thereof may have full or
limited voting powers. Upon adoption of such resolution, a statement shall be
filed with the Secretary of State in compliance with Minnesota Statutes Section
302A.401, before the issuance of any shares for which the resolution creates
rights or preferences not set forth in these Articles of Incorporation;
provided, however, where the shareholders have received notice of the creation
of shares with rights or preferences not set forth in these Articles of
Incorporation before the issuance of the shares, the statement may be filed any
time within one year after the issuance of the shares.

      C. Except in respect of characteristics of a particular series fixed by
the Board of Directors, all shares of Preferred Stock shall be of equal rank and
shall be identical. All shares of any one series of Preferred Stock so
designated by the Board of Directors shall be alike in every particular, except
that the shares of any one series issued at different times may differ as to the
dates from which dividends thereon shall be cumulative.

      D. Subject to the preferences of any series of Preferred Stock, the Board
of Directors may, in its discretion, out of funds legally available for the
payment of dividends and at such times and in such manner as determined by the
Board of Directors, declare and pay dividends on the Common Stock of the
Corporation. No dividend (other than a dividend in capital stock ranking on a
parity with the Common Stock or cash in lieu of fractional shares with respect
to such stock dividend) shall be declared or paid on any share or shares of any
class of stock or series thereof ranking on a parity with the Common Stock in
respect of payment of dividends for any period unless there shall have been
declared, for the same dividend period, like proportionate dividends on all
shares of Common Stock then outstanding.

      E. In the event of any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary after payment or provision for
payment of the debts and other liabilities of the Corporation and payment or
setting aside for payment of any preferential amount due to the holders of any
other class or series of stock, the holders of the Common Stock shall be
entitled to receive ratably any or all assets remaining to be paid or
distributed.

      F. The holders of the Common Stock of the Corporation shall be entitled to
one vote for each share of such stock held by them.

                                      2
<PAGE>
      G. Whenever reference is made in this Article V to shares "ranking prior
to" another class of stock or "on a parity with" another class of stock, such
reference shall mean and include all other shares of the Corporation in respect
of which the rights of the holders thereof as to the payment of dividends or as
to distributions in the event of a voluntary or involuntary liquidation,
dissolution or winding up of the affairs of the Corporation are given preference
over, or rank on an equal basis with, as the case may be, the rights of the
holders of such other class of stock. Whenever reference is made to shares
"ranking junior to" another class of stock, such reference shall mean and
include all shares of the Corporation in respect of which the rights of the
holders thereof as to the payment of dividends and as to distributions in the
event of a voluntary or involuntary liquidation, dissolution or winding up of
the affairs of the Corporation are junior and subordinate to the rights of the
holders of such class of stock. Except as otherwise provided in these Articles
of Incorporation, or in the statement filed with the Secretary of State in
compliance with Minnesota Statutes Section 306A.401, each series of Preferred
Stock ranks on a parity with each other and each ranks prior to the Common
Stock. Common Stock ranks junior to Preferred Stock.

      H. The Corporation shall at all times reserve and keep available, out of
its authorized but unissued shares of Common Stock or out of shares of Common
Stock held in its treasury, the full number of shares of Common Stock into which
all shares of any series of Preferred Stock having conversion privileges from
time to time outstanding are convertible. Unless otherwise provided in these
Articles of Incorporation or in the statement filed with the Secretary of State
in compliance with, Minnesota Statutes Section 306A.401, with respect to a
particular series of Preferred Stock, all shares of Preferred Stock, redeemed or
acquired (as a result of conversion or otherwise) shall be retired and restored
to the status of authorized but unissued shares.

                                  ARTICLE VI
                                   DIRECTORS

      A. The number of directors of the Corporation shall be fixed as specified
or provided for in the By-Laws of the Corporation. Election of directors need
not be by written ballot unless the By-Laws shall so provide.

      B. Any director or the entire Board of Directors may be removed, but only
by a 68% vote of the holders of the shares then entitled to vote at an election
of directors.

      C. Any director absent from a meeting of the Board of Directors or any
committee thereof may be represented by any other Director, who may cast the
vote of the absent director according to the written instructions, general or
special, of the absent director (except that the same person may not be
designated to act as proxy for more than one (1) director at any meeting of the
Board of Directors or any committee thereof).

      D. The Board of Directors, when evaluating a tender offer or an offer to
make a tender or exchange offer or to effect a merger, consolidation or share
exchange or sale of all or substantially all of the assets of the Corporation,
may, in exercising its judgment in determining what is in the best interests of
the Corporation and its shareholders, consider the following factors and any
other factors that it deems relevant: (1) not only the consideration being
offered in the proposed transaction, in relation to the then current market
price for the outstanding capital stock of the Corporation, but also the market
price for the 

                                      3
<PAGE>
capital stock of the Corporation over a period of years, the estimated price
that might be achieved in a negotiated sale of the Corporation as a whole or in
part or through orderly liquidation, the premiums over market price for the
securities of other corporations in similar transactions, current political,
economic and other factors bearing on securities prices and the Corporation's
financial condition and future prospects; (2) the social and economic effects of
such transaction on the Corporation, its subsidiaries, or their employees,
customers, creditors and the communities in which the Corporation and its
subsidiaries do business; (3) the business and financial condition and earnings
prospects of the acquiring party or parties; including, but not limited to, debt
service and other existing or likely financial obligations of the acquiring
party or parties, and the possible effect of such condition upon the Corporation
and its subsidiaries and the communities in which the Corporation and its
subsidiaries do business; and (4) the competence, experience, and integrity of
the acquiring party or parties and its or their management. Notwithstanding any
provision of this Article VI(D), this Article is not intended to confer any
rights on any subsidiary of the Corporation, or on any of the Corporation's or
its subsidiaries' employees, customers, creditors or other members of the
communities in which it or they do business.

                                  ARTICLE VII
                              SHAREHOLDER VOTING

       No shareholder of this Corporation shall be entitled to any cumulative
voting rights. Action shall not be taken by written consent of the Shareholders,
but, in all cases, shall be taken at a meeting of the Shareholders as described
in the By-Laws of the Corporation.

                                 ARTICLE VIII
                               PREEMPTIVE RIGHTS

      Except as provided in that certain 1997 Amended and Restated Shareholders
Agreement dated as of April 11, 1997 (as amended pursuant thereto from time to
time), no shareholder of this Corporation shall have any preferential,
preemptive, or other rights of subscription to any shares of any class or series
of stock of this Corporation allotted or sold or to be allotted or sold, whether
now or hereafter authorized, or to any obligations or securities convertible
into any class or series of stock of this Corporation.

                                  ARTICLE IX
                              DIRECTOR LIABILITY

      A director of this Corporation shall not be personally liable to the
Corporation or its shareholders for monetary damages for breach of fiduciary
duty as a director, except for (i) liability based on a breach of the duty of
loyalty to the Corporation or the shareholders; (ii) liability for acts or
omissions not in good faith or that involve intentional misconduct or a knowing
violation of law; (iii) liability based on the payment of an improper dividend
or an improper repurchase of the Corporation's stock under Minnesota Statutes,
Section 302A.559, or on material violations of federal or state securities laws;
(iv) liability for any transaction from which the director derived a material
improper personal benefit; or (v) liability for any act or omission occurring
prior to the date this Article IX becomes effective. If Minnesota Statutes,
Chapter 302A, hereafter is amended to authorize the further elimination or
limitation of the liability of directors, then the liability of a director of
the Corporation in addition to the limitation on personal liability 

                                      4
<PAGE>
provided herein, shall be limited to the fullest extent permitted by the amended
Chapter 302A. Any repeal of this provision as a matter of law or any
modification of this Article IX by the shareholders of the Corporation shall be
prospective only, and shall not adversely affect any limitation on the personal
liability of a director of the Corporation existing at the time of such repeal
or modification.

                                   ARTICLE X
                        BOARD ACTION WITHOUT A MEETING

      Any action required or permitted to be taken at any meeting of the Board
of Directors may be taken without a meeting by written action signed by all of
the Directors then in office.

                                  ARTICLE XI
               AMENDMENT TO ARTICLES OF INCORPORATION OR BYLAWS

      In furtherance of, and not in limitation of, the powers conferred by
statute, the Board of Directors is expressly authorized to adopt, amend or
repeal the By-Laws of the Corporation or adopt new By-Laws, without any action
on the part of the shareholders; provided, however, that no such adoption,
amendment, or repeal shall be valid with respect to By-Law provisions which have
been adopted, amended, or repealed by the shareholders; and further provided,
that By-Laws adopted or amended by the Board of Directors and any powers thereby
conferred may be amended, altered, or repealed by the shareholders. In addition,
the affirmative vote of the holders of at least (a) 80% of the voting power of
the then outstanding shares of voting stock, voting together as a single class,

voting together as a single class, and in addition to any other vote required by
these Articles of Incorporation or the By-Laws, is required to amend the
provisions of these Articles of Incorporation relating to the Minnesota Control
Share Acquisition Act or the Minnesota Business Combinations Act contained in
Article XII hereof.

                                  ARTICLE XII

                MINNESOTA STATUTES  SS.SS.  302A.671 AND 302A.673
            (CONTROL SHARE ACQUISITIONS AND BUSINESS COMBINATIONS)

      The Corporation and its shareholders hereby expressly elect to not have

hereafter amended from time to time, the Control Share Acquisition Act, apply to
any Control Share Acquisition (as in such statute defined) involving the
Corporation. The Corporation and its shareholders also hereby expressly elect

                                  ARTICLE 3.

                             SHAREHOLDERS MEETINGS

      SECTION 3.01.  REGULAR MEETINGS
      (1) Regular meetings of the Shareholders of the Corporation for the
purpose of election of Directors and transaction of such other business as may
properly come before the regular meetings may be held annually at the principal
executive office of the Corporation or at such other place within or without the
State of Minnesota or Texas as may be designated by the Board of Directors.
Regular meetings of Shareholders, when held, shall be held on the second Tuesday
in May of each year at 10:00 a.m., or at such date and time as the Board of
Directors may from time to time designate. Regular meetings of the Shareholders
(but not special meetings) may also be called by the Shareholders in accordance
with the provisions of Minnesota Statutes Chapter 302A. Regular meetings of the
Shareholders shall be known as "annual meetings."

      (2) At the annual meeting of the Shareholders, only such business shall be
conducted as shall have been properly brought before the annual meeting. To be
properly brought before the annual meeting of Shareholders, business must be (i)
specified in the notice of meeting (or any supplement thereto) given by or at
the direction of the Board of Directors, (ii) otherwise brought before the
meeting by or at the direction of the Board of Directors, or (iii) otherwise
properly brought before the meeting by a Shareholder of the Corporation who is a
Shareholder of record at the time of giving of notice provided for in this
Section 3.01 of Article 3, who shall be entitled to vote at such meeting and who
complies with the notice procedures set forth in this Section 3.01 of Article 3.
For business to be properly brought before an annual meeting by a Shareholder,
the Shareholder, in addition to the requirements set forth above, must have
given timely notice thereof in writing to the Secretary of the Corporation. To
be timely, a Shareholder's notice must be delivered to or mailed and received at
the principal executive offices of the Corporation not less than ninety (90)
days prior to the anniversary date of the immediately preceding annual meeting
of Shareholders of the Corporation. A Shareholder's notice to the Secretary
shall set forth as to each matter the Shareholder proposes to bring before the
annual meeting: (a) a brief description of the business desired to be brought
before the annual meeting and the reasons for conducting such business at the
annual meeting, (b) the name and address, as they appear on the Corporation's
books, of the Shareholder proposing such business, (c) the class and number of
shares of voting stock of the Corporation which are 

                                      2
<PAGE>
beneficially owned by the Shareholder, (d) a representation that the Shareholder
intends to appear in person or by proxy at the meeting to bring the proposed
business before the annual meeting, and (e) a description of any material
interest of the Shareholder in such business. Notwithstanding anything in these
By-Laws to the contrary, no business shall be conducted at an annual meeting
except in accordance with the procedures set forth in this Article 3. The
presiding officer of an annual meeting shall, if the facts warrant, determine
and declare to the meeting that business was not properly brought before the
meeting in accordance with the provisions of this Article 3, and if he should so
determine, he shall so declare to the meeting and any such business not properly
brought before the meeting shall not be transacted.

      SECTION 3.02. SPECIAL MEETINGS. Special meetings of the Shareholders may
be called for any purpose at any time by the Chief Executive Officer or a
majority of the Board of Directors. The Board of Directors or the Chief
Executive Officer shall within thirty (30) days of receipt of such written
request cause a special meeting of Shareholders to be called, said meeting to be
held no later than ninety (90) days after receipt of the written request.

      SECTION 3.03. NOTICE OF SHAREHOLDER MEETINGS. Written notice of
Shareholders' meetings, whether regular or special, shall be mailed to all
Shareholders entitled to vote at any such meeting at least ten (10) days, and
not more than sixty (60) days, before the date of the meeting. The written
notice shall contain the date, time and place of the meeting and, in the case of
a special meeting, the purpose or purposes thereof.

      SECTION 3.04. WAIVER OF NOTICE. Failure to receive notice of the time,
place and purpose of any meeting of Shareholders may be waived by any
Shareholder in writing or orally before, at, or after the meeting. Attendance by
a Shareholder at a meeting is a waiver of notice of that meeting, except where
the Shareholder objects at the beginning of the meeting to the transaction of
business because the meeting is not lawfully called or convened, or objects
before a vote on an item of business because the item may not lawfully be
considered at that meeting and does not participate in the consideration of the
item at that meeting.

                                      3
<PAGE>
      SECTION 3.05. RECORD DATE. The Board of Directors may fix in advance a
date not more than sixty (60) days prior to the date of any meeting of
Shareholders as the record date for the determination of Shareholders entitled
to vote at the meeting.

      SECTION 3.06. QUORUM. The presence, in person or by proxy, of the holders
of a majority of the outstanding shares entitled to vote thereat shall
constitute a quorum for the transaction of business at all meetings of
Shareholders. If, however, a quorum is not present or represented at any meeting
of Shareholders, the Shareholders entitled to vote at the meeting, either
present in person or represented by proxy, shall have the power to adjourn the
meeting to a future date. The time and place to which an adjournment is taken
shall be publicly announced at the meeting, and no further notice thereof shall
be necessary. 

      Provided that a quorum is present or represented at an adjourned meeting,
any business may be transacted which might have been transacted at the original
meeting. If a quorum is present when a duly called or held meeting of
Shareholders is convened, the Shareholders present may continue to transact
business until adjournment, even though the withdrawal of a number of
Shareholders originally present leaves less than the proportion or number
otherwise required for a quorum.

      SECTION 3.07. VOTING. A Shareholder entitled to vote at a meeting of
Shareholders may vote in person or by proxy. Except as otherwise provided by law
or the Articles of Incorporation, every Shareholder shall be entitled to one
vote for each share outstanding in his name on the record of Shareholders of the
Corporation. The votes of a corporate Shareholder may be cast in person or by
proxy, and shall be executed by any duly elected officer of a corporate
Shareholder.

      SECTION 3.08. PROXIES. Every appointment of a proxy must be in writing and
must be dated and signed by the Shareholder and filed with an officer of the
Corporation at or before the Shareholders' meeting at which the appointment is
to be effective. No appointment of a proxy shall be valid after the expiration
of eleven (11) months from the date of its execution, unless a longer period is
expressly provided in the appointment.

      SECTION 3.09. NOMINATION FOR ELECTION AS A DIRECTOR. Except as provided in
the Shareholders Agreement, only persons who are nominated in accordance with
the procedures set forth in these ByLaws 

                                      4
<PAGE>
shall be eligible for election as, and to serve as, directors. Nominations of
persons for election to the Board of Directors of the Corporation may be made at
a meeting of Shareholders (a) by or at the direction of the Board of Directors
or (b) by any Shareholder of the Corporation who is a Shareholder of record at
the time of giving of notice provided for in this Section 3.09, who shall be
entitled to vote for the election of directors at the meeting and who complies
with the notice procedures set forth in this Section 3.09. Such nominations,
other than those made by or at the direction of the Board of Directors, shall be
made pursuant to timely notice in writing to the Secretary of the Corporation.
To be timely, a Shareholder's notice shall be delivered to or mailed and
received at the principal executive offices of the Corporation (i) with respect
to an election to be held at the annual meeting of the Shareholders of the
Corporation, not less than ninety (90) days prior to the anniversary date of the
immediately preceding annual meeting of Shareholders of the Corporation; and
(ii) with respect to an election to be held at a special meeting of Shareholders
of the Corporation, not later than the close of business on the tenth (10th) day
following the date on which notice of the date of the special meeting (whether
or not such notice of the date of the special meeting constitutes the "notice of
special meeting" required by Section 3.02 of Article 3 of these By-Laws) was
mailed to Shareholders or public disclosure of the date of the special meeting
was made, whichever first occurs. Such Shareholder's notice to the Secretary
shall set forth (i) as to each person whom the Shareholder proposes to nominate
for election or re-election as a director, all information relating to such
person that is required to be disclosed in solicitations of proxies for election
of directors, or is otherwise required, pursuant to Regulation 14A under the
Securities Exchange Act of 1934, as amended (including such person's written
consent to being named in the proxy statement as a nominee and to serve as a
director if elected); and (ii) as to the Shareholder giving the notice (a) the
name and address, as they appear on the Corporation's books, of such Shareholder
and (b) the class and number of shares of voting stock of the Corporation which

Directors, any person nominated by the Board of Directors for election as a
director shall furnish to the Secretary of the Corporation that information
required to be set forth in a Shareholder's notice of nomination which pertains
to the nominee. In the event that a person is validly designated as a nominee to
the Board of Directors in accordance with the procedures set forth in this
Section 3.09 and shall thereafter become unable or unwilling to stand for
election to the Board of Directors, the Board of Directors or the Shareholder
who proposed such nominee, as the case may be, may designate a substitute
nominee. Other than directors chosen pursuant to this Section 3.09, no person
shall be eligible to serve as a director of the Corporation unless nominated in
accordance with the procedures set forth in this Section 3.09 of Article 3.

The presiding officer of the meeting of Shareholders shall, if the facts
warrant, determine and declare to the meeting that a nomination was not made in
accordance with the procedures prescribed by these By-Laws, and if he should so
determine, he shall so declare to the meeting and the defective nomination shall
be disregarded. Notwithstanding the foregoing provisions of this Section 3.09, a
Shareholder shall also comply with all applicable requirements of the Securities
Exchange Act of 1934, as amended, and the rules and regulations thereunder with
respect to the matters set forth in this Section 3.09.

      SECTION 3.10. NO SHAREHOLDER ACTION BY WRITTEN CONSENT. Action shall not
be taken by written consent of the Shareholders but, in all cases, shall be
taken at a meeting of the Shareholders as described in this Article 3.

                                  ARTICLE 4.

                                   DIRECTORS

      SECTION 4.01. DUTIES AND POWERS. The business and affairs of the
Corporation shall be managed by or under the direction of the Board of Directors
(hereinafter, the "Board of Directors" or "Board"), subject to any Shareholder
control agreement entered into in accordance with Minnesota Statutes Chapter
302A, including, without limitation, the Shareholders Agreement. The Board shall
take action by the affirmative vote of a majority of the Directors present at a
meeting, except as otherwise provided by law, or the Shareholders Agreement, or
the Articles of Incorporation; provided a quorum is present. The Board may adopt
such rules and regulations for the conduct of its meetings and the management of
the Corporation as it deems appropriate, consistent with law, the Shareholders
Agreement, these By-Laws and the Articles of Incorporation.

      SECTION 4.02. ELECTION OF DIRECTORS. Directors need not be U.S. citizens
or Shareholders of the Corporation. The number of directors of the Corporation
shall be fixed as provided in the Shareholders Agreement or when such agreement
is no longer in effect, from time to time by the Directors or Shareholders
pursuant to these By-laws. The Directors shall be classified, with respect to
the time for which they severally hold office, into three classes, as nearly
equal in number as possible, as shall be provided in the manner specified in the
Shareholders Agreement and these By-laws, one class to be originally elected for
a term expiring at the annual meeting of Shareholders to be 

                                      6
<PAGE>
held in 1997, another class to be originally elected for a term expiring at the
annual meeting of Shareholders to be held in 1998, and another class to be
originally elected for a term expiring at the annual meeting of Shareholders to
be held in 1999, with the members of each class to hold office until their
successors are elected and qualified. At each annual meeting of Shareholders of
the Corporation, the successors of the class of directors whose term expires at
the meeting shall be elected to hold office for a term expiring at the annual
meeting of Shareholders held in the third year following the year of their
election.

      SECTION 4.03. TERM OF OFFICE. Subject to the Shareholders Agreement, newly
created directorships resulting from any increase in the number of directors and
any vacancies on the Board of Directors resulting from death, resignation,
disqualification, removal or other cause shall be filled by the affirmative vote
of a majority of the remaining directors then in office, even though less than a
quorum of the Board of Directors. Any Director elected in accordance with the
preceding sentence shall hold office for the remainder of the full term of the
class of Directors in which the new directorship was created or the vacancy
occurred and until such Director's successor shall have been elected and
qualified. No decrease in the number of Directors constituting the Board of
Directors shall shorten the term of any incumbent Director.

      SECTION 4.04. REGULAR MEETINGS. The Board of Directors may, pursuant to a
standing resolution of the Board, provide for Board meetings to be held at
regular intervals. Such meetings shall be known as "regular meetings" and may be
held at such place or places, within or without the State of Texas or Minnesota,
as the Board shall designate from time to time. No notice of the purpose of
regular meetings of the Board shall be required.

      SECTION 4.05. SPECIAL MEETINGS. Special meetings of the Board of Directors
of the Corporation may be called BY ANY TWO (2) Directors by giving ten (10)
days notice to all Directors of the date, time, place and purpose of the
meeting. Such notice shall be given to each Director by registered mail or by
facsimile or by a notice in writing delivered to the Director personally or to
his usual place of business.

      SECTION 4.06. PREVIOUSLY SCHEDULED MEETINGS. If the day or date, time and
place of a Board meeting have been provided in these By-Laws or announced at a
previous meeting of the Board, no notice 

                                      7
<PAGE>
is required. Notice of an adjourned meeting need not be given other than by
announcement at the meeting at which adjournment is taken.

      SECTION 4.07. WAIVER OF NOTICE AND ASSENT TO ACTION. Failure to receive
notice of any meeting of the Board may be waived by any Director before, at or
after the meeting in writing or orally. Attendance by a Director at a meeting is
a waiver of notice of that meeting, except where the Director objects at the
beginning of the meeting to the transaction of business because the meeting is
not lawfully called or convened and does not participate thereafter in the
meeting.

      SECTION 4.08. QUORUM. The presence of a majority of the Directors shall
constitute a quorum for the transaction of business. In the absence of a quorum,
a majority of the Directors present may adjourn a meeting of the Board from time
to time until a quorum is present. If a quorum is present when a duly called or
held Board meeting is convened, the Directors present may continue to transact
business until adjournment, even though the withdrawal of a number of Directors
originally present leaves less than the proportion or number otherwise required
for a quorum.

      SECTION 4.09. ABSENT DIRECTORS. A Director may give advance written
consent or opposition to a proposal to be acted on at a Board meeting. If the
Director is not present at the meeting, consent or opposition to a proposal does
not constitute presence for purposes of determining the existence of a quorum,
but consent or opposition shall be counted as a vote in favor of or against the
proposal and shall be entered in the minutes or other record of action at the
meeting, if the proposal acted on at the meeting is substantially the same or
has substantially the same effect as the proposal to which the Director has
consented or objected.

      SECTION 4.10. VOTING. At all meetings of the Board of Directors, each
Director shall have one (1) vote irrespective of the number of shares that he
may hold. The Board of Directors shall take action by the affirmative vote of a
majority of Directors present at a duly held meeting at which a quorum is
present or voting pursuant to Section 4.08 of these By-Laws, except where the
affirmative vote of a larger proportion or number is required by law or the
Articles of Incorporation or the Shareholders Agreement.

      SECTION 4.11. COMPENSATION. The compensation of Directors shall be as
fixed from time to time by the Board of Directors.

      SECTION 4.12. VACANCIES. Subject to the Shareholders Agreement, vacancies
on the Board of Directors resulting from the death, resignation, removal, or
disqualification of a Director may be filled by the affirmative vote of a
majority of the remaining Directors, even though less than a quorum. Each
Director elected under this section to fill a vacancy shall hold office until a
qualified successor is elected by the Shareholders.

      SECTION 4.13. REMOVAL. Subject to the Shareholders Agreement, a Director
may be removed only by the Shareholders as provided in the Corporation's
Articles of Incorporation.

      SECTION 4.14. RESIGNATION. A Director may resign at any time by giving
written notice to the Corporation. The resignation is effective without
acceptance when the notice is given to the Corporation, unless a later effective
time is specified in the notice.

      SECTION 4.15. ELECTRONIC COMMUNICATIONS. A conference among Directors by
any means of communication through which the Directors may simultaneously hear
each other during the conference constitutes a Board meeting, if the same notice
is given of the conference as would be required under these By-Laws for a Board
meeting, and if the number of Directors participating in the conference would be
sufficient to constitute a quorum at a meeting. A Director may participate in a
Board meeting at which he is not personally present by any means of
communication through which the Director, other Directors so participating, and
all Directors physically present at the meeting may simultaneously hear each
other during the meeting. Participation in a Board meeting by any of the
foregoing means constitutes presence in person at the meeting.

      SECTION 4.16. WRITTEN ACTIONS. Any action required or permitted to be
taken at a Board meeting may be taken by a written action signed collectively,
or individually in counterparts, by all Directors. Any such written action shall
be effective when signed by all the Directors, unless a different effective time
is provided in the written action.

                                      9
<PAGE>
      SECTION 4.17. COMMITTEES. The Board of Directors may from time to time, by
resolution, adopted by the affirmative vote of a majority of the Directors
present at a duly called Board Meeting, establish one or more committees having
the authority of the Board in the management of the business of the Corporation
to the extent provided in the resolution. Any committee so established shall
consist of one (1) or more natural persons and shall be subject at all times to
the direction and control of the Board of Directors. At any meeting of any such
committee the presence of a majority of the members of the committee shall be
necessary to constitute a quorum for the transaction of business. Unless a
larger or smaller proportion or number is provided for in the resolution
establishing a committee, such committee shall take action by the affirmative
vote of a majority of committee members present at a duly held meeting.

      SECTION 4.18. POWER TO AMEND BY-LAWS. In furtherance and not in limitation
of the powers conferred by statute, the Board of Directors is expressly
authorized to make, alter or repeal from time to time the By-Laws of the
Corporation in any manner not inconsistent with the laws of the State of
Minnesota or the Articles of Incorporation of the Corporation or the
Shareholders Agreement.

                                  ARTICLE 5.

                                   OFFICERS

Agreement, any officer of the Corporation may be removed at any time, with or
without cause, by the affirmative vote of a majority of 

                                      10

may be filled by the Board of Directors.

Chairman who shall report directly to the Board of Directors) .

      SECTION 5.08. COMPENSATION. The Compensation of all officers of the
Corporation shall be fixed by the Board of Directors or by such committee or
person as the Board may from time to time designate.

                                  ARTICLE 6.

                                    SHARES

      SECTION 6.01. CERTIFICATES. The shares of the Corporation shall be
represented by certificates approved by the Board of Directors and signed by any
two (2) of the Chairman, President or Chief Financial Officer. Each certificate
shall state the name of the Corporation, that the Corporation is incorporated in
Minnesota, the name of the person to whom it is issued, the number and class or
series of shares represented thereby, the date of issue, the par value of such
shares, if any, and may contain such other provisions as the Board or the
Shareholders Agreement may designate.

      SECTION 6.02. SIGNATURE. For the purpose of facilitating the execution of
stock certificates, the Board of Directors may appoint one or more additional
persons, having power to sign stock certificates, or to execute any instrument
on behalf of the Corporation which shall have been approved by the Board of

<PAGE>
      SECTION 6.03. TRANSFER OF SHARES. The shares of the Corporation shall be

shares surrendered to the person or persons entitled thereto.

complained of in the proceeding, the person:

      (a)   Has not, pursuant to the provisions of Section 7.1.1 (c) of these
            By-Laws, been indemnified by another organization or employee
            benefit plan for the same judgments, penalties, fines (including,
            without limitation, excise taxes assessed against the person with
            respect to an employee benefit plan), settlements, and reasonable
            expenses (including attorneys' fees and disbursements), incurred by
            the person in connection with the proceeding with respect to the
            same acts or omissions;

(a) upon receipt by the Corporation of a written affirmation by the person of a
good faith belief that the criteria for indemnification set forth in Section
7.02 have been satisfied and a written undertaking by the person to repay all
amounts so paid or reimbursed by the Corporation, if it is ultimately determined
that the criteria for indemnification set forth in Section 7.02 have not been
satisfied, and (b) after a determination that the facts then known to those
making the determination pursuant to Section 7.05 would not preclude
indemnification under this Article 7. The written undertaking required by clause
(a) is an unlimited general obligation of the person making it, but need not be
secured and shall be accepted without reference to financial ability to make the
repayment.

      SECTION 7.04. REIMBURSEMENT TO WITNESSES. This Article 7 does not require,

                  time parties to the proceeding (Board members who are part of
                  the proceeding shall not be counted for determining either a
                  majority or the presence of a quorum); or

            (b)   If a quorum under Clause (a) cannot be obtained, in accordance
                  with Minnesota Statutes Chapter 302A; or

            (c)   If an adverse determination is made or if no determination is
                  made within 60 (sixty) days after the termination of a
                  proceeding or after a request for an advance of expenses, as
                  the case may be, by a court in this state, which may be the
                  same court in which the proceeding concerning the person's
                  liability took place, upon application of the person and any
                  notice the court requires.

            7.5.2. ALTERNATIVE PROCEDURE FOR NON-MANAGEMENT. With respect to a
      person who is not, and was not at the time of the acts or omissions

      possessing, directly or indirectly, the power to direct or cause the
      direction of the management or policies of the Corporation, the
      determination whether indemnification of this person is required because
      the criteria set forth in Section 7.02 have been satisfied and whether
      this person is entitled to payment or reimbursement or expenses in advance
      of the final disposition of a proceeding as provided in Section 7.03 may
      be made by an annually appointed committee of the Board, having at least
      one member who is a director. The committee shall report at least annually
      to the Board concerning its actions.

      7.06. DISCLOSURE. If the Corporation indemnifies or advances expenses to a
person in accordance with this Article 7 in connection with a proceeding by or
on behalf of the Corporation, it shall report the amount of the indemnification
or advance and to whom and on whose behalf it was made as part of the annual
financial statements furnished to Shareholders pursuant to Minnesota Statutes
Chapter 302A covering the period when the indemnification or advance was paid or
accrued under the accounting method of the Corporation reflected in the
financial statements.

Corporation or is or was serving at the request of the Corporation as a
director, officer, senior management, employee or agent of another corporation,

the Corporation would have the power to indemnify such person against such
expense, liability or loss under the Minnesota Business Corporation Act.

      7.08. SAVINGS CLAUSE. If this Article 7 or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify and hold harmless each director and
officer of the Corporation, as to costs, charges and expenses (including,
without limitation, attorney's fees and disbursements), judgments, fines, and
amounts paid in settlement with respect to any action, suit or proceeding,
whether civil, criminal, administrative or investigative to the full extent
permitted by any applicable portion of this Article 7 that shall not have been
invalidated and to the fullest extent permitted by applicable law.

Standards Board and/or the American Institute of Certified Public Accountants or
any similar accounting body of comparable standing, and shall be recommended by
Borrower's certified public accountants, to the extent that such changes would
modify such accounting terms or the interpretation or computation thereof as
contemplated by this Agreement at the time of execution hereof, then in such
event such changes shall be followed in defining such accounting terms only
after Lender and Borrower amend this Agreement to reflect the original intent of
such terms in light of such changes, and such terms shall continue to be applied
and interpreted without such change until such agreement.

        1.3. OTHER TERMS. All other terms contained in this Agreement shall
have, when the context so indicates, the meanings provided for by the Code to
the extent the same are used or defined therein.

        1.4. CERTAIN MATTERS OF CONSTRUCTION. The terms "herein", "hereof" and
"hereunder" and other words of similar import refer to this Agreement as a whole
and not to any particular section, paragraph or subdivision. Any pronoun used
shall be deemed to cover all genders. The section titles, table of contents and
list of exhibits appear as a matter of convenience only and shall not affect the
interpretation of this Agreement. All references to statutes and related
regulations shall include any amendments of same and any successor statutes and
regulations. All references to any instruments or agreements, including, without
limitation, references to any of the Loan Documents, shall include any and all
modifications or amendments thereto and any and all extensions or renewals
thereof.

        1.5 THE TERM "BORROWER" OR BORROWERS". All references to "Borrower" or
"Borrowers" herein shall refer to and include each Borrower separately and all
representations contained herein shall be deemed to be separately made by each
of them, and each of the covenants, agreements and obligations set forth herein
shall be deemed to be the joint and several covenants, agreements and
obligations of them. Any notice, request, consent, report or other information
or agreement delivered to Lender by any Borrower shall be deemed to be ratified
by, consented to and also delivered by the other Borrower. Each Borrower
recognizes and agrees that each covenant and agreement of "Borrower" or
"Borrowers" under this Agreement and the Other Agreements shall create a joint
and several obligation of the Borrowers, which may be enforced against
Borrowers, jointly, or against each Borrower separately. Without limiting the
terms of this Agreement and the Other Agreements, security interests granted
under this Agreement and Other Agreements in properties, interests, assets and
collateral shall extend to the properties, interests, assets and collateral of
each Borrower. Similarly, the term "Obligations" shall include, without
limitation, all obligations, liabilities and indebtedness of such corporations,
or any one of them, to Lender, whether such obligations, liabilities and
indebtedness shall be joint, several, joint and several or individual.

        1.6 CAL DIVE OBLIGATIONS. Notwithstanding any other provision of the
Equipment Note or this Agreement to the contrary, it is hereby agreed that ERT
is not assuming payment of the unpaid principal balance of the Obligations which
was incurred by Cal Dive prior to the Closing Date pursuant to the Original Loan
Documents (the "CAL DIVE OBLIGATIONS"). However, the parties hereto agree and
acknowledge that the preceding sentence shall not (A) limit any contingent
liability of ERT for payment of any of the Cal Dive Obligations which arises
pursuant to the Guaranty Agreement, or (B) limit the Liens in favor of Lender
granted by ERT against the assets of ERT as a result of ERT becoming an
additional named "Borrower", which Liens shall secure payment of all Obligations
arising in connection with this Agreement, whether currently existing or
hereafter arising. For purposes of determining on or after the date hereof which
Obligations outstanding constitute Cal Dive Obligations, all payments received
by Lender on account of the Obligations shall be deemed to be applied first in
payment of the Cal Dive Obligations until such time as the Cal Dive Obligations
shall have been reduced to zero, and thereafter to the other Obligations as
hereinafter set forth.

                           SECTION 2. CREDIT FACILITY

        Subject to the terms and conditions of, and in reliance upon the
representations and warranties made in, this Agreement and the other Loan
Documents, Lender agrees to make a total credit facility of up to Thirty Million
Dollars ($30,000,000.00) available upon Borrower's request therefor, as follows:

        2.1.   REVOLVING CREDIT LOANS.

        (A) Subject to all of the terms and conditions of this Agreement, Lender
agrees, for so long as no Event of Default exists, to make Revolving Credit
Loans to Borrower from time to time, as requested by Borrower in accordance with
the terms of SECTION 2.3, up to a maximum principal amount at any time
outstanding equal to the Borrowing Base at such time. It is expressly understood
and agreed that Lender shall use the Borrowing Base as a maximum ceiling on
Revolving Credit Loans outstanding to Borrower at any time. If the unpaid
balance of the Revolving Credit Loans should exceed the Borrowing Base or any
other limitation set forth in this Agreement, such Revolving Credit Loans shall
nevertheless constitute Obligations that are secured by the Collateral and
entitled to all the benefits thereof; PROVIDED, HOWEVER, if such an overadvance
occurs, Borrower shall immediately repay, without premium or penalty, Revolving
Credit Loans in an amount equal to such excess, along with accrued unpaid
interest on the amount so repaid to the date of such repayment. In no event
shall Borrower be authorized to request a Revolving Credit Loan at any time that
there exists an Event of Default.

        (B) Notwithstanding the foregoing provisions of SECTION 2.1(A), Lender
shall have the right to establish reserves (in addition to the Contingency
Reserve) in such amounts, and with respect to such matters, as Lender shall deem
necessary or appropriate, against the amount of Revolving Credit Loans which
Borrower may otherwise request under SECTION 2.1(A), including, without
limitation, with respect to (i) price adjustments, damages, unearned discounts,
returned products or other matters for which credit memoranda are issued in the
ordinary course of Borrower's business; (ii) other sums chargeable against
Borrower's Loan Account as Revolving Credit Loans under any section of this
Agreement; (iii) sales tax liabilities; (iv) price adjustments, damages,
returned products or other matters related to contractual obligations of
Borrower; (v) offset exposure relating to contractual obligations of Borrower;
and (vi) such other matters, events, conditions or contingencies as to which
Lender, in its credit judgment, determines reserves should be established from
time to time hereunder.

        (C) The Revolving Credit Loans shall be used solely for (i) the payment
of costs, expenses and fees relating to the Loans to be made under this
Agreement, (ii) the payment of principal and interest under the Equipment Loans,
(iii) the purchase of the capital stock of Borrower, and (iv) Borrower's general
operating capital needs, to the extent not inconsistent with the provisions of
this Agreement.

        2.2. EQUIPMENT LOANS.

        (A) Subject to all of the terms and conditions of this Agreement, Lender
agrees, for so long as no Event of Default exists, to make Equipment Loans to
Borrower, from time to time, in accordance with the terms of SECTION 2.3, up to
a maximum principal amount which, the aggregate of, shall not exceed the
Equipment Borrowing Base at such time. It is expressly understood and agreed
that Lender shall use the Equipment Borrowing Base as a maximum ceiling on
Equipment Loans outstanding to Borrower at any time. If the unpaid balance of
the Equipment Loans should exceed the Equipment Borrowing Base or any other
limitation set forth in this Agreement, such Equipment Loans shall nevertheless
constitute Obligations that are secured by the Collateral and entitled to the
benefits thereof; PROVIDED, HOWEVER, if such an overadvance occurs, (i) a
request for a Revolving Credit Loan shall be deemed to be made by Borrower in an
amount equal to such excess PLUS accrued unpaid interest on the amount of such
excess, to repay such overadvance, provided there is sufficient availability
under the Borrowing Base for such Revolving Credit Loan or (ii) if there is
insufficient availability under the Borrowing Base for such Revolving Credit
Loan, then Borrower shall immediately repay, without premium or penalty,
Equipment Loans in an amount equal to such excess, along with accrued unpaid
interest on the amount so repaid to the date of such repayment. The Equipment
Commitment will mature simultaneously with the termination of the Revolving
Credit Commitment. In no event shall a Borrower be authorized to request an
Equipment Loan at any time there exists an Event of Default.

        (B) If Borrower sells any of the Equipment, or any Offshore Platform, or
if any of the Collateral is taken by condemnation, Borrower shall pay to Lender,
unless otherwise agreed by Lender, as and when received by Borrower and as a
mandatory payment of the Loans (or, at Lender's option, such of the other
Obligations as Lender may elect), a sum equal to the proceeds received by
Borrower from such sale or condemnation.

        (C) The Equipment Loans shall be used solely by Borrower for purposes
for which the proceeds of the Revolving Credit Loans are authorized to be used,
and to finance Borrower's purchase of Equipment and oil and gas Properties.

        2.3. MANNER OF BORROWING REVOLVING CREDIT LOANS AND EQUIPMENT LOANS.
Borrowings under the Revolving Credit Commitment and Equipment Commitment shall
be as follows:

        (A) A request for a Eurodollar Loan shall be made, or shall be deemed to
be made, if Borrower gives Lender notice of its intention to borrow in the form
of EXHIBIT A (a "BORROWING NOTICE"), in which notice Borrower shall specify (i)
the aggregate amount of such Eurodollar Loan, (ii) the requested date of such
Eurodollar Loan, (iii) the Applicable Annual Rate selected in accordance with
SECTION 3.1, and (iv) the Eurodollar Interest Period applicable thereto. If
Borrower selects a Eurodollar Loan, Borrower shall give Lender the Borrowing
Notice at least two (2) Business Days prior to the requested date of the
Eurodollar Loan.

        (B) A request for a Base Rate Loan shall be made, or shall be deemed to
be made, if (i) Borrower sends by facsimile transmission to (214) 828-6531, or
such other number as Lender may designate, a request for a Base Rate Loan prior
to 12:00 p.m. Central Standard Time on the Business Day on which Borrower is
requesting such Base Rate Loan (if a request is received after such time on a
Business Day, Lender, in its sole discretion, may make the requested Base Rate
Loan on the day of such notice or on the next following Business Day); (ii)
Borrower fails to pay any interest accruing under this Agreement or the
Equipment Note on the date such interest becomes due and payable, or (iii)
Borrower fails to pay any other Obligations under this Agreement on the date
such Obligations become due and payable. The amount of Base Rate Loans advanced
according to clause (i) shall be for the amount requested. The amount of Base
Rate Loans advanced according to clauses (ii) and (iii) shall be deemed to be an
amount equal to the amount of interest that was not actually paid by Borrower or
the amount of funds actually disbursed, respectively.

        (C) Borrower hereby irrevocably authorizes Lender to disburse the
proceeds of each Loan requested, or deemed to be requested, pursuant to this
SECTION 2.3 as follows: (i) the proceeds of each Loan requested under SECTIONS
2.3(A) or 2.3(B)(I) shall be disbursed by Lender in lawful money of the United
States of America in immediately available funds, in the case of the initial
borrowing, in accordance with the terms of the written disbursement letter from
Borrower, and in the case of each subsequent borrowing, by wire transfer to such
bank account as may be agreed upon by Borrower and Lender from time to time; and
(ii) the proceeds of each Revolving Credit Loan requested under SECTION
2.3(B)(II) or (III) shall be disbursed by Lender by way of direct payment of the
relevant Obligation.

        2.4. LETTERS OF CREDIT; LC GUARANTIES. If requested to do so by Borrower
and subject to the terms of this Agreement and any documents executed in
connection with any Letter of Credit or LC Guaranty, Lender may attempt to cause
Bank to issue, in its good faith discretion, Letters of Credit for the account
of Borrower or execute LC Guaranties; PROVIDED, THAT, no Event of Default then
exists. The aggregate face amount of all Letters of Credit issued by Lender or
Bank and LC Guaranties outstanding at any time shall not exceed Five Million
Dollars ($5,000,000.00). No Letter of Credit issued by Lender or Bank and no LC
Guaranty shall have a term exceeding one year and shall, upon expiration, be
renewable for an additional period. Notwithstanding the foregoing, no Letter of
Credit issued by Lender or Bank and no LC Guaranty may have an expiration date
that is after the last day of the Original Term, or, if this Agreement remains
in effect after the Original Term, after the last day of any Renewal Term then
in effect. Any amounts paid by Lender under any LC Guaranty or in connection
with any Letter of Credit shall be deemed to be advances of Revolving Credit
Loans and Obligations under this Agreement.

        2.5. ALL LOANS TO CONSTITUTE ONE OBLIGATION. All Loans shall constitute
one general joint and several obligation of Borrowers, and shall be secured by
Lender's security interest in and Lien upon all of the Collateral, and by all
other security interests and Liens heretofore, now or at any time or times
hereafter granted by Borrower to Lender.

        2.6. LOAN ACCOUNT. Lender shall enter all Loans as debits to the Loan
Account and shall also record in the Loan Account all payments made by Borrowers
on each Loan and all proceeds of Collateral which are finally paid to Lender,
and may record therein, in accordance with customary accounting practices, all
charges and expenses properly chargeable to Borrower hereunder.

        2.7    JOINT AND SEVERAL LIABILITY; RIGHTS OF CONTRIBUTION.

        (A) Each Borrower states and acknowledges that: (i) pursuant to this
Agreement, Borrowers desire to utilize their borrowing potential on a
consolidated basis to the same extent possible if they were merged into a single
corporate entity; (ii) it has determined that it will benefit specifically and
materially from the advances of credit contemplated by this Agreement; (iii) it
is both a condition precedent to the obligations of Lender hereunder and a
desire of the Borrowers that each Borrower execute and deliver to Lender this
Agreement; and (iv) Borrowers have requested and bargained for the structure and
terms of and security for the advances contemplated by this Agreement.

        (B) Each Borrower hereby irrevocably and unconditionally: (i) agrees
that it is jointly and severally liable to Lender for the full and prompt
payment of the Obligations and the performance by each Borrower of its
obligations hereunder in accordance with the terms hereof; (ii) agrees to fully
and promptly perform all of its obligations hereunder with respect to each
advance of credit hereunder as if such advance had been made directly to it; and
(iii) agrees as a primary obligation to indemnify Lender on demand for and
against any loss incurred by Lender as a result of any of the obligations of any
Borrower being or becoming void, voidable, unenforceable or ineffective for any
reason whatsoever, whether or not known to Lender or any Person, the amount of
such loss being the amount which Lender would otherwise have been entitled to
recover from Borrower.

        (C) It is the intent of each Borrower that the indebtedness, obligations
and liability hereunder of no one of them be subject to challenge on any basis.
Accordingly, as of the date hereof, the liability of each Borrower under this
SECTION 2.7, together with all of its other liabilities to all Persons as of the
date hereof and as of any other date on which a transfer is deemed to occur by
virtue of this Agreement, calculated in amount sufficient to pay its probable
net liabilities on its existing Indebtedness as the same become absolute and
matured ("DATED LIABILITIES ") is, and is to be, less than the amount of the
aggregate of a fair valuation of its property as of such corresponding date
("DATED ASSETS"). To this end, each Borrower under this SECTION 2.7, (i) grants
to and recognizes in each other Borrower, ratably, rights of subrogation and
contribution in the amount, if any, by which the Dated Assets of such Borrower,
but for the aggregate of subrogation and contribution in its favor recognized
herein, would exceed the Dated Liabilities of such Borrower or, as the case may
be, (ii) acknowledges receipt of and recognizes its right to subrogation and
contribution ratably from the other Borrower in the amount, if any, by which the
Dated Liabilities of such Borrower, but for the aggregate of subrogation and
contribution in its favor recognized herein, would exceed the Dated Assets of
such Borrower under this SECTION 2.7. In recognizing the value of the Dated
Assets and the Dated Liabilities, it is understood that Borrowers will
recognize, to at least the same extent of their aggregate recognition of
liabilities hereunder, their rights to subrogation and contribution hereunder.
It is a material objective of this SECTION 2.7 that each Borrower recognizes
rights to subrogation and contribution rather than be deemed to be insolvent (or
in contemplation thereof) by reason of an arbitrary interpretation of its joint
and several obligations hereunder.

                  SECTION 3.  INTEREST, FEES, TERM, REDUCTION AND REPAYMENT

        3.1. INTEREST, FEES AND CHARGES.

        (A) INTEREST. Outstanding principal on the Loans shall bear interest at
the option of Borrower (subject to the terms and conditions herein) at either
the Base Rate or Eurodollar Base Rate, calculated daily, at the following rates
per annum (individually called, as applicable, an "APPLICABLE ANNUAL RATE"): (i)
each Eurodollar Loan shall bear interest at a rate per annum equal to two and
one quarter percent (2.25%) above the Eurodollar Base Rate for the Eurodollar
Interest Period applicable thereto if the principal aggregate amount of Loans
outstanding is less than Ten Million Dollars ($10,000,000) on the date of the
Borrowing Notice for such Eurodollar Loan, (ii) each Eurodollar Loan shall bear
interest at a rate per annum equal to two percent (2.00%) above the Eurodollar
Base Rate for the Eurodollar Interest Period applicable thereto if the aggregate
principal amount of Loans outstanding is Ten Million Dollars ($10,000,000) or
more on the date of the Borrowing Notice for such Eurodollar Loan, and (iii) the
Base Rate Loans shall bear interest at a fluctuating rate per annum equal to
one-half of one percent (0.50%) above the Base Rate. The interest rate
applicable to Base Rate Loans shall be increased or decreased, as the case may
be, by an amount equal to any increase or decrease in the Base Rate, with such
adjustments to be effective as of the opening of business on the day that any
such change in the Base Rate becomes effective. The Base Rate in effect on the
date hereof shall be the Base Rate effective as of the opening of business on
the date hereof, but if this Agreement is executed on a day that is not a
Business Day, the Base Rate in effect on the date hereof shall be the Base Rate
effective as of the opening of business on the last Business Day immediately
preceding the date hereof. Interest on the Loans shall be calculated daily,
based on the actual days elapsed over a three hundred-sixty (360) day year.
Further, for the purpose of computing interest, all items of payment received by
Lender shall be applied by Lender (subject to final payment of all drafts and
other items received in form other than immediately available funds) against the
Obligations on the day of receipt. The determination of when a payment is
received by Lender will be made in accordance with SECTION 3.6.

        (B) DEFAULT RATE OF INTEREST. Upon and after the occurrence of an Event
of Default, and during the continuation thereof, the principal amount of the
Loans and other Obligations shall bear interest, calculated daily (computed on
the actual days elapsed over a three hundred-sixty (360) day year), at two
percent (2.00%) above the Applicable Annual Rate or other applicable rate of
interest (a "DEFAULT RATE").

        (C) MAXIMUM RATE OF INTEREST. Notwithstanding anything to the contrary
in this Agreement or otherwise, (i) if at any time the amount of interest
computed on the basis of an Applicable Annual Rate or a Default Rate would
exceed the amount of such interest computed upon the basis of the maximum rate
of interest permitted by applicable state or federal law in effect from time to
time hereafter (the "MAXIMUM LEGAL RATE"), the interest payable under this
Agreement shall be computed upon the basis of the Maximum Legal Rate, but any
subsequent reduction in such Applicable Annual Rate or Default Rate, as
applicable, shall not reduce such interest thereafter payable hereunder below
the amount computed on the basis of the Maximum Legal Rate until the aggregate
amount of such interest accrued and payable under this Agreement equals the
total amount of interest which would have accrued if such interest had been at
all times computed solely on the basis of an Applicable Annual Rate or Default
Rate, as applicable; and (ii) unless preempted by federal law, an Applicable
Annual Rate or Default Rate, as applicable, from time to time in effect
hereunder may not exceed the "indicated ceiling rate" from time to time in
effect under Tex. Rev. Civ. Stat. Ann. art 5069-1.04(c) (Vernon 1987). If the
applicable state or federal law is amended in the future to allow a greater rate
of interest to be charged under this Agreement than is presently allowed by
applicable state or federal law, then the limitation of interest hereunder shall
be increased to the maximum rate of interest allowed by applicable state or
federal law as amended, which increase shall be effective hereunder on the
effective date of such amendment, and all interest charges owing to Lender by
reason thereof shall be payable upon demand.

        (D) EXCESS INTEREST. No agreements, conditions, provisions or
stipulations contained in this Agreement or any other instrument, document or
agreement between Borrower and Lender or default of Borrower, or the exercise by
Lender of the right to accelerate the payment of the maturity of principal and
interest, or to exercise any option whatsoever contained in this Agreement or
any other Loan Document, or the arising of any contingency whatsoever, shall
entitle Lender to contract for, charge, or receive, in any event, interest
exceeding the Maximum Legal Rate. In no event shall Borrower be obligated to pay
interest exceeding such Maximum Legal Rate and all agreements, conditions or
stipulations, if any, which may in any event or contingency whatsoever operate
to bind, obligate or compel Borrower to pay a rate of interest exceeding the
Maximum Legal Rate, shall be without binding force or effect, at law or in
equity, to the extent only of the excess of interest over such Maximum Legal
Rate. In the event any interest is contracted for, charged or received in excess
of the Maximum Legal Rate ("EXCESS"), Borrower acknowledges and stipulates that
any such contract, charge, or receipt shall be the result of an accident and
bona fide error, and that any Excess received by Lender shall be applied, first,
to reduce the principal then unpaid hereunder; second, to reduce the other
Obligations; and third, returned to Borrower, it being the intention of the
parties hereto not to enter at any time into a usurious or otherwise illegal
relationship. Borrower recognizes that, with fluctuations in the Base Rate and
the Maximum Legal Rate, such a result could inadvertently occur. By the
execution of this Agreement, Borrower covenants that (i) the credit or return of
any Excess shall constitute the acceptance by Borrower of such Excess, and (ii)
Borrower shall not seek or pursue any other remedy, legal or equitable, against
Lender, based in whole or in part upon contracting for, charging or receiving of
any interest in excess of the maximum authorized by applicable law. For the
purpose of determining whether or not any Excess has been contracted for,
charged or received by Lender, all interest at any time contracted for, charged
or received by Lender in connection with this Agreement shall be amortized,
prorated, allocated and spread in equal parts during the entire term of this
Agreement.

        (E) INCORPORATION BY THIS REFERENCE. The provisions of SECTION 3.1(D)
shall be deemed to be incorporated into every document or communication relating
to the Obligations which sets forth or prescribes any account, right or claim or
alleged account, right or claim of Lender with respect to Borrower (or any other
obligor in respect of Obligations), whether or not any provision of this SECTION
3.1 is referred to therein. All such documents and communications and all
figures set forth therein shall, for the sole purpose of computing the extent of
the Obligations and obligations of the Borrowers (or other obligor) asserted by
Lender thereunder, be automatically re-computed by any Borrower or obligor, and
by any court considering the same, to give effect to the adjustments or credits
required by SECTION 3.1(D).

        (F) UNUSED COMMITMENT FEE. From the date hereof, Borrower agrees to pay
to Lender an annual unused commitment fee of Ten Thousand Dollars ($10,000.00).
Such unused commitment fee shall be payable (i) on the Closing Date, and (ii) on
each anniversary date of the Closing Date during the term of this Agreement.

        (G) CAPITAL ADEQUACY CHARGE. In the event that Lender shall have
determined in good faith that the adoption of any law, rule or regulation
regarding capital adequacy, or any change therein or in the interpretation or
application thereof or compliance by Lender with any request or directive
regarding capital adequacy (whether or not having the force of law) from any
central bank or governmental authority, does or shall have the effect of
reducing the rate of return on Lender's capital as a consequence of its
obligations hereunder to a level below that which Lender could have achieved but
for such adoption, change or compliance (taking into consideration Lender's
policies with respect to capital adequacy) by an amount deemed by Lender, in its
sole discretion, to be material, then from time to time, after submission by
Lender to Borrower of a certificate certifying the amount by which such rate of
return is actually reduced with respect to this transaction, together with the
calculation and a written demand therefor, Borrower shall promptly pay to Lender
such additional amount or amounts as will compensate Lender for such reduction;
PROVIDED, THAT, Lender's other debtors are required to reimburse Lender for the
same type of reduction. The certificate of Lender claiming entitlement to
payment as set forth above shall be conclusive in the absence of manifest error.
Such certificate shall set forth the nature of the occurrence giving rise to
such payment, the additional amount or amounts to be paid to Lender, and the
method by which such amounts were determined. In determining such amount, Lender
may use any reasonable averaging and attribution method, so long as it
accurately reflects the reduction. Lender agrees to provide Borrower such
additional information with respect thereto upon request.

        (H) LETTER OF CREDIT; LC GUARANTY FEES. As additional consideration for
Lender's issuing its, or causing Bank to issue its Letters of Credit for
Borrower's account or for issuing its LC Guaranties at Borrower's request
pursuant to SECTION 2.4, Borrower agrees to pay to Lender, in addition to
Lender's costs and expenses incurred in issuing such Letters of Credit and LC
Guaranties, fees equal to two percent (2.00%) per annum of the face amount of
each Letter of Credit and LC Guaranty, which fee shall be deemed fully earned
upon issuance of each such Letter of Credit or LC Guaranty, and shall be due and
payable in equal monthly installments beginning on the first Business Day of the
month following the date of issuance of such Letter of Credit or LC Guaranty and
continuing on the first Business Day of each month thereafter during the term
thereof. No fee payable by Borrower to Lender under this SECTION 3.2(H) shall be
subject to rebate or proration upon the termination of this Agreement for any
reason.

        3.2. ADDITIONAL PROVISIONS REGARDING EURODOLLAR LOANS.

        (A) Borrower may select a Eurodollar Base Rate with respect to all or
any portion of the Loans as provided in this SECTION 3.2; PROVIDED, HOWEVER,
that (i) each Eurodollar Loan shall be in a principal amount of not less than
One Million Dollars ($1,000,000) (and, if greater than One Million Dollars
($1,000,000), in integral multiples of One Hundred Thousand Dollars ($100,000)),
(ii) no more than five (5) Eurodollar Interest Periods may be in existence at
any one time, and (iii) Borrower may not select a Eurodollar Base Rate for a
Loan if there exists a Default or Event of Default. Borrower shall select
Eurodollar Interest Periods with respect to Eurodollar Loans so that no
Eurodollar Interest Period expires after the end of the Original Term, or if
extended pursuant to SECTION 3.3, any Renewal Term. With respect to a Eurodollar
Loan, the Borrowing Notice shall be delivered to Lender not later than two (2)
Business Days before the proposed borrowing date referenced therein. An
outstanding Base Rate Loan may be converted to a Eurodollar Loan at any time
subject to the provisions of this SECTION_3.2.

        (B) Each Eurodollar Loan shall bear interest from and including the
first day of the Eurodollar Interest Period applicable thereto (but not
including the last day of such Eurodollar Interest Period) at the interest rate
determined as applicable to such Eurodollar Loan, but interest on such
Eurodollar Loan shall be payable as provided in SECTION 3.6. If at the end of an
Eurodollar Interest Period for an outstanding Eurodollar Loan, Borrower has
failed to deliver to Lender a new Borrowing Notice with respect to such
Eurodollar Loan or to pay such Eurodollar Loan, then such Eurodollar Loan shall
be converted to a Base Rate Loan on and after the last day of such Eurodollar
Interest Period and shall remain a Base Rate Loan until paid or until the
effective date of a new Borrowing Notice with respect thereto.

        (C) If Lender determines that maintenance of any of its Eurodollar Loans
would violate any applicable law, rule, regulation or directive, whether or not
having the force of law, Lender shall suspend the availability of Eurodollar
Loans and require any Eurodollar Loans outstanding to be repaid; or if Lender
determines that (i) deposits of a type or maturity appropriate to match fund
Eurodollar Loans are not available, or (ii) the Eurodollar Base Rate does not
accurately reflect the cost of making a Eurodollar Loan, then Lender shall
promptly provide notice to Borrower of its decision to suspend Borrower's
ability to make Eurodollar Loans and/or require Borrower to repay all Eurodollar
Loans and shall suspend the availability of Eurodollar Loans after the date of
any such determination.

        (D) If any payment of a Eurodollar Loan occurs on a date which is not
the last day of the applicable Eurodollar Interest Period, whether because of
acceleration, prepayment or otherwise, or a Eurodollar Loan is not made on the
date specified by Borrower because Borrower has not satisfied the conditions
precedent to such Eurodollar Loan contained in this Agreement or a Default or
Event of Default has occurred and is continuing, Borrower will indemnify Lender
for any loss or cost incurred by it resulting therefrom, including without
limitation any loss or cost in liquidating or employing deposits required to
fund or maintain the Eurodollar Loan.

        (E) Lender shall deliver a written statement as to the amount due, if
any, under SECTIONS 3.2(C) or (D). Such written statement shall set forth in
reasonable detail the calculations upon which Lender determined such amount and
shall be final, conclusive and binding on Borrower in the absence of manifest
error. Determination of amounts payable under such Sections in connection with a
Eurodollar Loan shall be calculated as though Lender funded its Eurodollar Loan
through the purchase of a deposit of the type and maturity corresponding to the
deposit used as a reference in determining the Eurodollar Base Rate applicable
to such Loan whether in fact that is the case or not. Unless otherwise provided
herein, the amount specified in the written statement shall be payable on demand
after receipt by Borrower of the written statement.

        3.3. TERM OF AGREEMENT. Subject to Lender's right to cease making Loans
to Borrower at any time upon or after the occurrence of an Event of Default,
this Agreement shall be in effect for (a) a period of five (5) years from the
date hereof, through and including May 22, 2000 (the " ORIGINAL TERM"), and (b)
an additional one year period, through and including May 22, 2001 unless
terminated by either Lender or Borrower by giving written notice of such
termination to the other party no less than ninety (90) days prior to the end of
the Original Term (the "RENEWAL TERM"). Upon written request by Borrower, Lender
may, in its sole and absolute discretion, renew this Agreement for any number of
successive one year periods thereafter (each such successive one year period, a
"Renewal Term"), but Lender shall have no obligation to do so. Notwithstanding
anything contained herein to the contrary, Lender may terminate this Agreement
without notice upon or after the occurrence of an Event of Default.

        3.4.   EARLY TERMINATION BY BORROWER.

        (A) Borrower may prepay the Loans at any time during the term of this
Agreement, in whole or in part, without premium, penalty or liquidated damages.
However, if Borrower chooses to terminate the Revolving Credit Commitment, the
Equipment Commitment and this Agreement (which all must terminate
simultaneously) in its entirety, Borrower shall give Lender at least ninety (90)
days prior written notice thereof if such termination occurs during the first
twelve-month period of the Original Term, and at least six (6) months prior
written notice thereof if such termination occurs during any other time, and, on
the designated termination date, all of the Obligations shall become due and
payable, in immediately available funds, and all Credit Enhancements issued by
Lender or Bank shall have expired or otherwise been terminated.

        (B) At the effective date of any termination by Borrower under SECTION
3.4(A) of the entire Revolving Credit Commitment, the Equipment Commitment and
this Agreement, Borrower shall pay to Lender (in addition to the then
outstanding principal, accrued interest and other charges owing under the terms
of this Agreement and any of the other Loan Documents, as liquidated damages for
the loss of the bargain and not as a penalty, an amount equal to 1.50% of the
Termination Amount if such termination occurs during the first twelve-month
period of the Original Term (May 23, 1995 through May 22, 1996). If termination
occurs at any other time during the Original Term, during any Renewal Term, or
within one hundred-eighty (180) days from the date Lender submits a certificate
to Borrower certifying a reduction in Lender's rate of return pursuant to
SECTION 3.1(G), no liquidated damages shall be payable.

        3.5 EFFECT OF TERMINATION. All of the Obligations shall be forthwith due
and payable upon any termination of this Agreement in accordance with SECTION
3.4. Except as otherwise expressly provided for in this Agreement or the other
Loan Documents, no termination or cancellation (regardless of cause or
procedure) of this Agreement or any of the other Loan Documents shall in any way
affect or impair the rights, powers or privileges of Lender or the obligations,
duties or liabilities of Borrower or Lender in any way relating to (A) any
transaction or event occurring prior to such termination or cancellation or (B)
any of the undertakings, agreements, covenants, warranties or representations of
Borrower contained in this Agreement or any of the other Loan Documents. All
such undertakings, agreements, covenants, warranties and representations of
Borrower shall survive such termination or cancellation and Lender shall retain
its Liens in the Collateral and all of its rights and remedies under this
Agreement and the other Loan Documents notwithstanding such termination or
cancellation until all of the Obligations known existing, threatened or claimed
which can be given a monetary value have been paid in full, in immediately
available funds.

        3.6. PAYMENTS. Principal and interest on the Equipment Loans shall be
payable as provided in the Equipment Note. Except where evidenced by notes or
other instruments issued or made by Borrower to Lender specifically containing
payment provisions which are in conflict with this SECTION 3.6 (in which event
the conflicting provisions of said notes or other instruments shall govern and
control), the Obligations shall be payable as follows:

        (A) principal payable on account of Revolving Credit Loans made by
Lender to Borrower pursuant to SECTION 2.1 of this Agreement shall be payable by
Borrower to Lender immediately upon the earliest of (i) the receipt by Lender or
Borrower of any proceeds of any of the Collateral, to the extent of said
proceeds, (ii) the occurrence of an Event of Default in consequence of which
Lender elects to accelerate the maturity and payment of such Loans, or (iii)
termination of this Agreement.

        (B) interest accrued on the Revolving Credit Loans shall be due on the
earliest of (i) the first day of each month (for the immediately preceding
month), computed through the last calendar day of the preceding month, (ii) the
occurrence of an Event of Default in consequence of which Lender elects to
accelerate the maturity and payment of the Obligations, or (iii) termination of
this Agreement.

        (C) reasonable and itemized costs, fees and expenses payable pursuant to
this Agreement shall be promptly payable by Borrower to Lender or to any other
Person designated by Lender in writing.

        (D) the balance of the Obligations requiring the payment of money, if
any, shall be payable by Borrower to Lender as and when provided in this
Agreement, the Other Agreements or the Security Documents, or, if not otherwise
provided, then on demand.

        Borrower hereby irrevocably authorizes Lender, in Lender's good faith
discretion, to advance to Borrower and to charge to the Loan Account as a
Revolving Credit Loan, sums sufficient to pay all amounts due and payable under
SECTIONS 3.6(B), (C) and (D) above and under the Equipment Note, whether or not
any such advance would cause the outstanding Revolving Credit Loans to exceed
the Borrowing Base.

        3.7. APPLICATION OF PAYMENTS AND COLLECTIONS. Except as otherwise
provided in this SECTION 3.7, Borrower irrevocably waives the right to direct
the application of any and all payments and collections at any time or times
hereafter received by Lender from or on behalf of Borrower, and Borrower does
hereby irrevocably agree that Lender shall have the continuing exclusive right
to apply and reapply any and all such payments and collections received at any
time or times hereafter by Lender or its agent against the Obligations, in such
manner as Lender may deem advisable, notwithstanding any entry by Lender upon
any of its books and records. If as the result of collections of Accounts as
authorized by SECTION 5.2 a credit balance exists in the Loan Account with
respect to the Revolving Credit Commitment, such credit balance shall not accrue
interest in favor of Borrower, but shall be returned to Borrower within one (1)
Business Day for so long as no Default or Event of Default exists. In no event
shall such credit balance be applied or be deemed to have been applied as a
payment of the Equipment Loans unless so requested by Borrower, but Lender may
offset such credit balance against the Obligations upon or after the occurrence
of an Event of Default. Payments and collections received by Lender from the
Dominion Account or otherwise in Chicago, Illinois (A) before 2:00 p.m. Central
Standard Time on a Business Day shall be deemed received on such Business Day,
and (B) after 2:00 p.m. Central Standard Time on a Business Day shall be deemed
received on the next succeeding Business Day, in each case for purposes of
determining the amount of Revolving Credit Loans and Equipment Loans available
for borrowing hereunder and for purposes of computing interest on the Loans
(subject in each case to final payment of all items and collections received in
form other than immediately available funds). For so long as no Event of Default
has occurred, all payments and collections deposited into the Dominion Account
shall be transferred to a bank account specified by Borrower, and upon the
occurrence of an Event of Default, Lender may, in its sole discretion, direct
all such payments and collections to be transferred to a bank account specified
by Lender. Borrower hereby agrees that it shall not (on a Consolidated basis)
maintain more than One Million Dollars ($1,000,000) in its bank operating
account.

        3.8. STATEMENTS OF ACCOUNT. Lender will account to Borrower monthly with
a statement of Loans, charges and payments made pursuant to this Agreement, and
such account rendered by Lender, absent manifest error, shall be deemed final,
binding and conclusive upon Borrower unless Lender is notified by Borrower in
writing to the contrary within seventy-five (75) days after the date each
account is mailed to Borrower. Such notice shall only be deemed an objection to
those items specifically objected to therein.

                      SECTION 4. COLLATERAL: GENERAL TERMS

        4.1. SECURITY INTEREST IN COLLATERAL. To secure the prompt payment and
performance to Lender of the Obligations, Borrower hereby grants to Lender a
continuing security interest in and Lien upon all the following Property and
interests in Property of Borrower, whether now owned or existing or hereafter
created, acquired or arising and wheresoever located:

        (A) Accounts;

        (B) Inventory;

        (C) Equipment (other than Equipment leased by Borrower);

        (D) General Intangibles;

        (E) all monies and other Property of any kind, now or at any time or
times hereafter, in the possession or under the control of Lender or a bailee of
Lender;

        (F) all accessions to, substitutions for and all replacements, products
and cash and non-cash proceeds of CLAUSES (A), (B), (C), (D) and (E) above,
including, without limitation, proceeds of and unearned premiums with respect to
insurance policies insuring any of the Collateral; ----------- --- --- --- ---
and

        (G) all books and records (including, without limitation, customer
lists, credit files, computer programs, print-outs, and other computer materials
and records) of Borrower pertaining to any of CLAUSES (A), (B), (C), (D), (E) or
(F) above.

The Collateral shall not include the monies held at Southwest Bank of Texas,
N.A. for the benefit of the Management Group and certain other employees of Cal
Dive pursuant to that certain Collateral Security Agreement, dated as of January
12, 1995 among Cal Dive, Southwest Bank of Texas, N.A., the Management Group and
the other parties named therein.

The security interests in the Collateral granted to Lender by Cal Dive are given
in renewal, extension and modification of the security interests previously
granted to Lender by Cal Dive in the Original Loan Documents; such prior
security interests are not extinguished hereby; and the making, perfection and
priority of such prior security interests shall continue in full force and
effect.

        4.2. LIEN ON MARINE VESSELS. The due and punctual payment and
performance of the Obligations shall be secured by the Lien created by the Ship
Mortgage upon all marine vessels owned by Cal Dive described therein. Except as
otherwise permitted herein, if Borrower shall acquire at any time or times
hereafter any interest in other marine vessels, Borrower hereby agrees to
promptly execute and deliver to Lender, as additional security and Collateral
for the Obligations, Ship Mortgages or other collateral assignments satisfactory
in form and substance to Lender and its counsel (herein collectively referred to
as "NEW SHIP MORTGAGES") covering such marine vessels. The Ship Mortgage and
each New Ship Mortgage shall be duly recorded in each port where such recording
is required to constitute a valid Lien on the marine vessels. Borrower shall
deliver to Lender such other documents as Lender and its counsel may reasonably
request relating to the Property subject to the Ship Mortgage and any New Ship
Mortgages.

        4.3. LIEN ON OIL AND GAS PROPERTIES. Upon the request of Lender, the due
and punctual payment and performance of the Obligations shall also be secured by
a Lien upon any interest of Borrower in the Offshore Platforms and all other oil
and gas Properties of Borrower. Borrower agrees that upon the request of Lender
such Borrower shall promptly execute and deliver to Lender, as additional
security and Collateral for the Obligations, deeds of trust, security deeds,
mortgages or other collateral assignments satisfactory in form and substance to
Lender and its counsel (herein collectively referred to as "NEW MORTGAGES")
covering such interests in the Offshore Platforms and other oil and gas
Properties. Each New Mortgage shall be duly recorded in each office where such
recording is required to constitute a valid Lien on Borrower's interest in the
Offshore Platforms and other oil and gas Properties covered thereby. Borrower
further agrees that until such time as Lender requests that a New Mortgage be
executed, such Borrower shall promptly execute and deliver to Lender a Negative
Pledge Agreement covering such Borrower's interest in the Offshore Platforms and
other oil and gas Properties. Each Negative Pledge Agreement shall be duly
recorded in each office where a New Mortgage covering such interest in the
Offshore Platforms and other oil and gas Properties would be required to be
filed. Upon request, Borrower shall deliver to Lender agreements, documents,
opinions, certificates and such other information as Lender and its legal
counsel may reasonably request, relating to Borrower's interest in the Offshore
Platforms and other oil and gas Properties subject to any Negative Pledge
Agreement or any New Mortgage.

        4.4. REPRESENTATIONS, WARRANTIES AND COVENANTS. To induce Lender to
enter into this Agreement, Borrower represents, warrants, and covenants to
Lender:

               (A) Subject to the statutory right of the MMS to approve the
acquisition of an Offshore Platform and related oil and gas Properties and the
provisions of the Buy-Sell Agreements, the Collateral is now and, so long as any
of the Obligations are outstanding, will continue to be owned solely by
Borrower, and no other Person has or will have any right, title, interest,
claim, or Lien therein, thereon or thereto other than a Permitted Lien.

               (B) Except for Permitted Liens or as specifically consented to in
writing by Lender, the Liens granted to Lender shall be first and prior on the
Collateral and as to the Accounts and proceeds, including insurance proceeds,
resulting from the sale, disposition, or loss thereof. No further action need be
taken to perfect the Liens granted to Lender, other than the filing of
continuation statements under the Code or other applicable law, continued
possession by Lender of that portion of the Collateral constituting instruments
or documents, the recording of the Ship Mortgage and each New Ship Mortgage
under the 1989 Act, and the recording of each New Mortgage with the applicable
filing offices.

               (C) All goods evidenced by the Collateral constituting chattel
paper, documents or instruments, the possession of which has been given to
Lender, are owned by Borrower and the same are free and clear of any prior Lien,
except for Statutory Liens contested by Borrower as required by SECTION 8.2(H).
Borrower further warrants and guarantees the value, quantities, adequate
condition, grades and qualities of the goods and services described therein.
Borrower shall pay and discharge when due all taxes, levies, and other charges
upon said Collateral and upon the goods evidenced by any documents constituting
Collateral, except and to the extent only that such taxes, levies and other
charges are being actively contested in good faith and by appropriate lawful
proceedings, and Borrower has established adequate reserves therefor, which are
properly reflected on the Consolidated Financial Statements, and the nonpayment
of such taxes, levies and charges does not result in a lien upon any Collateral
other than a Permitted Lien. Borrower shall defend Lender against and save it
harmless from all claims of any Person with respect to the Collateral. This
indemnity shall include reasonable attorneys' fees and legal expenses.

        4.5. LIEN PERFECTION. Borrower agrees to execute the UCC-1 financing
statements provided for by the Code or otherwise together with any and all other
instruments, assignments or documents and shall take such other action as may be
required to perfect or to continue the perfection of Lender's security interest
in the Collateral. Unless prohibited by applicable law, Borrower hereby
authorizes Lender to execute and file any such financing statement on Borrower's
behalf. The parties agree that a carbon, photographic or other reproduction of
this Agreement shall be sufficient as a financing statement and may be filed in
any appropriate office in lieu thereof.

        4.6. REAL PROPERTY LIEN DOCUMENTATION. Borrower agrees to execute for
Lender's benefit the leasehold mortgages, deeds of trust or other documents
evidencing a collateral assignment of Borrower's interest in certain real
Property owned or leased by Borrower and any additional real Property owned or
leased by Borrower as Lender may request. Such documents shall be recorded, at
the expense of Borrower, with such filing offices as may be required to evidence
Lender's Lien upon the real Property owned or leased or hereafter acquired by
Borrower.

        4.7. LOCATION OF COLLATERAL. All Collateral, other than Inventory in
transit, motor vehicles, marine vessels and diving equipment, will at all times
be kept by Borrower at one or more of the business locations set forth in
EXHIBIT D attached hereto and shall not, without the prior written approval of
Lender, be moved therefrom except, prior to an Event of Default, for (A) sales
of Inventory and the providing of services in the ordinary course of business;
(B) the storage of Inventory at locations within the continental United States
other than those shown on EXHIBIT D attached hereto if (i) Borrower gives Lender
written notice of the new storage location at least sixty (60) days prior to
storing Inventory at such location, (ii) except for Statutory Liens contested by
Borrower as required by SECTION 8.2(H), Lender's security interest in such
Inventory is and continues to be a duly perfected, first priority Lien thereon,
(iii) neither Borrower's nor Lender's right of entry upon the premises where
such Inventory is stored, or its right to remove the Inventory therefrom, is in
any way restricted, (iv) the owner of such premises agrees with Lender not to
assert any landlord's, bailee's or other Lien in respect of the Inventory for
unpaid rent or storage charges, and (v) all negotiable documents and receipts in
respect of any Collateral maintained at such premises are promptly delivered to
Lender; (C) temporary transfers (for period not to exceed three months in any
event) of Equipment from a location set forth on EXHIBIT D attached hereto to
another location if done for the limited purpose of repairing, refurbishing or
overhauling such Equipment in the ordinary course of Borrower's business; and
(D) removals in connection with dispositions of Equipment that are authorized by
SECTION 6.4.

        4.8. INSURANCE OF COLLATERAL. Borrower agrees to maintain and pay for
insurance upon all Collateral (other than Offshore Platforms) wherever located,
in storage or in transit, including goods evidenced by documents, covering
casualty, hazard, public liability and such other risks and in such amounts and
with insurance companies acceptable to Lender. Borrower shall deliver to Lender
certificates regarding such insurance and the originals of such policies when
available, with satisfactory endorsements naming Lender as loss payee or
co-insured and as mortgagee pursuant to a standard mortgagee clause. Each policy
of insurance or endorsement shall contain a clause requiring the insurer to give
not less than thirty (30) days prior written notice to Lender in the event of
cancellation of the policy for any reason whatsoever and a clause that the
interest of Lender shall not be impaired or invalidated by any act or neglect of
Borrower or owner of the Property nor by the occupation of the premises for
purposes more hazardous than are permitted by said policy. If Borrower fails to
provide and pay for such insurance, Lender may, at Borrower's expense, procure
the same, but shall not be required to do so. Borrower agrees to deliver to
Lender, promptly as rendered, true copies of all reports made in any reporting
forms to insurance companies. Borrower will maintain, with financially sound and
reputable insurers, insurance with respect to its Properties and business
against such casualties and contingencies of such type (including public
liability, product liability, larceny, embezzlement, or other criminal
misappropriation insurance) and in such amounts as is customary in the business
or as otherwise required by Lender.

        4.9. PROTECTION OF COLLATERAL. All insurance expenses and all expenses
of protecting, storing, warehousing, insuring, handling, maintaining and
shipping the Collateral, any and all excise, property, sales, and use taxes
imposed by any state, federal, or local authority on any of the Collateral or in
respect of the sale thereof shall be borne and paid by Borrower. If Borrower
fails to promptly pay any portion thereof when due or is not actively contesting
such taxes in good faith and by appropriate proceedings and has not established
adequate reserves, which are properly reflected on the Consolidated Financial
Statements, Lender may, at its option, but shall not be required to, pay the
same and charge the Loan Account therefor. Borrower agrees to reimburse Lender
promptly therefor with interest accruing thereon daily at the Applicable Annual
Rate for Base Rate Loans. All sums so paid or incurred by Lender for any of the
foregoing and all costs and expenses (including reasonable attorneys' fees,
legal expenses, and court costs) which Lender may incur in enforcing or
protecting its Lien on or rights and interest in the Collateral or any of its
rights or remedies under any Loan Document or in respect of any of the
transactions to be had hereunto, together with interest at the Default Rate
applicable to Base Rate Loans, shall be considered Obligations hereunder secured
by all Collateral. Lender shall not be liable or responsible in any way for the
safekeeping of any of the Collateral or for any loss or damage thereto (except
for reasonable care in the custody thereof while any Collateral is in Lender's
actual possession) or for any diminution in the value thereof, or for any act or
default of any warehouseman, carrier, forwarding agency, or other person
whomsoever, but the same shall be at Borrower's sole risk.

                   SECTION 5. PROVISIONS RELATING TO ACCOUNTS

        5.1. REPRESENTATIONS, WARRANTIES AND COVENANTS. With respect to all
Accounts, Borrower represents and warrants to Lender that Lender may rely, in
determining which Accounts are Eligible Accounts, on all statements and
representations made by Borrower with respect to any Account or Accounts, and,
unless otherwise indicated in writing to Lender, that with respect to each
Account:

               (A) it is genuine and in all respects what it purports to be, 
and it is not evidenced by a judgment;

               (B) it arises out of a completed, bona fide sale and delivery of
goods or rendition of services by Borrower in the ordinary course of its
business and in accordance with the terms and conditions of all purchase orders,
contracts or other documents relating thereto and forming a part of the contract
between Borrower and the Account Debtor;

               (C) except for the long-term Accounts due from Ivory Production
Co. and guaranteed by Blue Dolphin Energy Corporation outstanding as of the
Closing Date, it has been generated in compliance with Borrower's normal credit
policies as historically in effect (or as modified from time to time on prior
written notice to Lender) or on such other reasonable terms disclosed in writing
to Lender in advance of the creation of such Account, and such terms are
expressly set forth on the face of the invoice covering such sale or rendition
of services;

               (D) it is for a liquidated amount maturing as stated in the
duplicate invoice covering such sale or rendition of services, a copy of which
has been furnished or is available to Lender;

               (E) Borrower has made no agreement with any Account Debtor
thereunder for any deduction therefrom, except discounts or allowances which are
granted by Borrower in the ordinary course of its business and which are
disclosed to Lender;

               (F) to the best of Borrower's knowledge, there are no facts,
events or occurrences which have not been disclosed to Lender which in any way
impair the validity or enforceability thereof or tend to reduce the amount
payable thereunder from the face amount of the invoice and statements delivered
to Lender with respect thereto;

               (G) to the best of Borrower's knowledge, the Account Debtor
thereunder (i) is Solvent and (ii) had the capacity to contract at the time any
contract or other document giving rise to the Account was executed; and

               (H) Borrower has no knowledge of any fact or circumstance which
would impair the validity or collectability of the Account, and to the best of
Borrower's knowledge there are no proceedings or actions which are threatened or
pending against any Account Debtor thereunder which might result in any material
adverse change in such Account Debtor's financial condition or the
collectability of such Account.

        5.2. ASSIGNMENTS, RECORDS AND SCHEDULES OF ACCOUNTS. If so requested by
Lender, Borrower shall execute and deliver to Lender formal written assignments
of all of its Accounts on a monthly or more frequent basis, which shall include
all Accounts that have been created since the date of the last assignment,
together with copies of invoices or invoice registers related thereto. Borrower
shall keep accurate and complete records of its Accounts and all payments and
collections thereon and shall submit to Lender on a monthly basis, unless
requested on a more frequent basis by Lender, a sales and collections report for
the preceding month, in form satisfactory to Lender. On or before the last day
of each month from and after the date hereof, Borrower shall deliver to Lender,
in form satisfactory to Lender, a detailed listing of all Unbilled Accounts
existing as of the last day of the preceding month, a detailed aged trial
balance of all Accounts existing as of the last day of the preceding month,
specifying the names, face value, dates of invoices and due dates for each
Account Debtor obligated on an Account so listed and a listing of all disputed
amounts due and owing (a "SCHEDULE OF ACCOUNTS"), and upon Lender's request
therefor, the reason for any disputed amounts, all claims related thereto and
the amount in controversy, and addresses, copies of proof of delivery and the
original copy of all documents, including, without limitation, repayment
histories and present status reports relating to the Accounts so scheduled, and
such other matters and information relating to the status of then existing
Accounts as Lender shall reasonably request.

        5.3.   ADMINISTRATION OF ACCOUNTS.

               (A) Borrower shall report discounts, allowances or credits
granted by Borrower that are not shown on the face of the invoice for the
Account involved to Lender at the time of its submission to Lender of the next
Schedule of Accounts as provided in SECTION 5.2 or more frequently upon the
request of Lender. Upon and after the occurrence of an Event of Default, Lender
shall have the right to settle or adjust all disputes and claims directly with
the Account Debtor and to compromise the amount or extend the time for payment
of the Accounts upon such terms and conditions as Lender may deem advisable, and
to charge the deficiencies, costs and expenses thereof, including reasonable
attorney's fees, to Borrower.

               (B) If an Account includes a charge for any tax payable to any
governmental taxing authority, Lender is authorized, in its sole discretion, to
pay the amount thereof to the proper taxing authority for the account of
Borrower and to charge the Loan Account therefor. Borrower shall notify Lender
if any Account includes any tax due to any governmental taxing authority and, in
the absence of such notice, Lender shall have the right to retain the full
proceeds of the Account and shall not be liable for any taxes to any
governmental taxing authority that may be due by Borrower by reason of the sale
and delivery creating the Account.

               (C) Whether or not an Event of Default has occurred, any of
Lender's officers, employees or agents shall have the right, at any time or
times hereafter, in the name of Lender, any designee of Lender or Borrower, to
verify the validity, amount or any other matter relating to any Accounts by
mail, telephone, telegraph or otherwise. Borrower shall cooperate fully with
Lender in an effort to facilitate and promptly conclude any such verification
process.

        5.4.   COLLECTION OF ACCOUNTS.

               (A) To expedite collection, Borrower shall endeavor in the first
instance to make collection of its Accounts for Lender. All remittances received
by Borrower on account of Accounts shall be held as Lender's property by
Borrower as trustee of an express trust for Lender's benefit and Borrower shall
immediately deposit same in the Dominion Account. Lender shall have the right at
any time after the occurrence of an Event of Default to notify Account Debtors
that Accounts have been assigned to Lender and to collect Accounts directly in
its own name and to charge the collection costs and expenses, including
reasonable attorneys' fees, to Borrower. Lender has no duty to protect, insure,
collect or realize upon the Accounts or preserve rights in them.

               (B) Borrower shall deposit all proceeds of the Collateral or
cause the same to be deposited in kind in a Dominion Account pursuant to a
lockbox arrangement with such banks as may be selected by Borrower and be
acceptable to Lender. Borrower shall issue to any such bank, an irrevocable
letter of instruction directing such banks to deposit all payments or other
remittances received in the lockbox to the Dominion Account for application on
account of the Obligations. All funds deposited in the Dominion Account shall
immediately become the property of Lender and Borrower shall obtain the
agreement by such banks to waive any offset rights against the funds so
deposited. Lender assumes no responsibility for such lockbox arrangement,
including, without limitation, any claim of accord and satisfaction or release
with respect to deposits accepted by any bank thereunder.

       SECTION 6. PROVISIONS RELATING TO EQUIPMENT AND OFFSHORE PLATFORMS

               6.1. REPRESENTATIONS, WARRANTIES AND COVENANTS. With respect to
the Equipment and the Offshore Platforms, Borrower represents, warrants and
covenants to and with Lender that:

               (A) substantially all of the Equipment is in adequate operating
condition and repair, and all necessary replacements of and repairs thereto
shall be made so that the value and operating efficiency of the Equipment shall
be maintained and preserved, reasonable wear and tear excepted; and

               (B) except for Equipment affixed to Offshore Platforms in the
ordinary course of ERT's business (which Equipment shall not be included in the
Equipment Borrowing Base), Borrower will not permit any of the Equipment to
become affixed to any real Property leased to Borrower so that an interest
arises therein under the real estate laws of the applicable jurisdiction unless
the landlord of such real Property has executed a landlord waiver or leasehold
mortgage in favor of Lender, and Borrower will not permit any of the Equipment
to become an accession to any personal Property other than Equipment subject to
first priority Liens in favor of Lender or subject to Permitted Liens.

        6.2. EVIDENCE OF OWNERSHIP OF EQUIPMENT. Immediately on request therefor
by Lender, Borrower shall deliver to Lender any and all evidence of ownership,
if any, of any of the Equipment.
               

        6.3. RECORDS AND SCHEDULES OF EQUIPMENT. Borrower shall maintain
accurate records itemizing and describing the kind, type, quality, quantity and
value of its Equipment and all dispositions made in accordance with SECTION 6.4,
and shall furnish Lender with a current schedule, in form and substance
satisfactory to Lender, containing the foregoing information on at least an
annual basis and more often if requested by Lender.

        6.4. DISPOSITIONS. Borrower will not sell, lease or otherwise dispose of
or transfer any of the Equipment, any Offshore Platform or any oil and gas
Properties, or any part thereof without the prior written consent of Lender;
PROVIDED, HOWEVER, that the foregoing restriction shall not apply to
dispositions required by the United States government, or, for so long as no
Event of Default exists, to (A) (i) dispositions of Offshore Platforms, oil and
gas Properties and related Equipment by ERT in the ordinary course of business,
or (ii) dispositions of any other Equipment which, in the aggregate during any
consecutive twelve-month period, has a fair market value or book value,
whichever is less, of One Hundred Fifty Thousand Dollars ($150,000) or less;
PROVIDED, THAT, all proceeds thereof are turned over to Lender, or (B)
replacements of Equipment that is substantially worn, damaged or obsolete with
Equipment of like kind, function and value; PROVIDED, THAT, (i) the replacement
Equipment shall be acquired prior to or concurrently with any disposition of the
Equipment that is to be replaced, (ii) the replacement Equipment shall be free
and clear of Liens other than Permitted Liens, (iii) Borrower shall give Lender
at least five (5) days prior written notice of such disposition and (iv)
Borrower shall turn over to Lender all proceeds realized from any such
disposition.

                         SECTION 7.  REPRESENTATIONS AND WARRANTIES

        7.1. GENERAL REPRESENTATIONS AND WARRANTIES. To induce Lender to enter
into this Agreement and to make advances hereunder, Borrower warrants,
represents and covenants to Lender as follows:
               

               (A) ORGANIZATION AND QUALIFICATION. Borrower is a corporation
duly organized, validly existing and in good standing under the laws of the
state of its incorporation. Borrower has duly qualified and is authorized to do
business and is in good standing as a foreign corporation in each state or
jurisdiction listed on EXHIBIT E attached hereto and made a part hereof and in
all other states and jurisdictions where the character of its Properties or the
nature of its activities make such qualification necessary.

               (B) CORPORATE NAMES. Since July 27, 1990, Cal Dive, and since
September 30, 1992, ERT, have not been known as or used any corporate,
fictitious or trade names except as disclosed on EXHIBIT F attached hereto and
made a part hereof. Except as set forth on EXHIBIT F attached hereto, Borrower
has not, during the preceding three years, been the surviving corporation of a
merger or consolidation or acquired all or substantially all of the assets of
any Person.

               (C) CORPORATE POWER AND AUTHORITY. Borrower has the right and
power and is duly authorized and empowered to enter into, execute, deliver and
perform this Agreement and each of the other Loan Documents to which it is a
party. The execution, delivery and performance of this Agreement and each of the
other Loan Documents have been duly authorized by all necessary corporate action
and do not and will not (i) require any consent or approval of the shareholders
of Borrower; (ii) contravene Borrower's charter, articles of incorporation or
by-laws; (iii) violate, or cause Borrower to be in default under, any provision
of any law, rule, regulation, order, writ, judgment, injunction, decree,
determination or award in effect having applicability to Borrower; (iv) result
in a breach of or constitute a default under any indenture or loan or credit
agreement or any other agreement, lease or instrument to which Borrower is a
party or by which it or its Properties may be bound or affected; or (v) result
in, or require, the creation or imposition of any Lien (other than Permitted
Liens) upon or with respect to any of the Properties now owned or hereafter
acquired by Borrower.

               (D) LEGALLY ENFORCEABLE AGREEMENT. This Agreement is, and each of
the other Loan Documents when delivered under this Agreement will be, a legal,
valid and binding obligation of Borrower enforceable against it in accordance
with their respective terms, except to the extent that such enforcement may be
limited by applicable bankruptcy, insolvency and other similar laws affecting
creditors' rights generally or by principles of equity pertaining to the
availability of equitable remedies.

               (E) USE OF PROCEEDS. Borrower's uses of the proceeds of any Loans
pursuant to this Agreement are, and will continue to be, legal and proper
corporate uses, duly authorized by its Board of Directors, and such uses will
not violate any applicable laws, including, without limitation, the Foreign
Assets Control Regulations, the Foreign Funds Control Regulations and the
Transaction Control Regulations of the United States Treasury Department (31
CFR, Subtitle B, Chapter V, as amended), where the failure to do so would have a
material adverse effect on its business, condition (financial or otherwise),
operations, prospects, or Properties.

               (F) MARGIN STOCK. Borrower is not engaged principally, or as one
of its important activities, in the business of purchasing or carrying "margin
stock" (within the meaning of Regulation G or U of the Board of Governors of the
Federal Reserve System), and no part of the proceeds of any Loans to Borrower
will be used to purchase or carry any margin stock or to extend credit to others
for the purpose of purchasing or carrying any margin stock or be used for any
purpose which violates or is inconsistent with the provisions of Regulation G,
T, U or X of said Board of Governors.

               (G) GOVERNMENTAL CONSENTS. Except where failure to do so would
have a material adverse effect on its business, condition (financial or
otherwise), operations, prospects, or Properties, Borrower has, and is in good
standing with respect to, all governmental consents, approvals, authorizations,
permits, certificates, inspections, and franchises necessary to continue to
conduct its business as heretofore or proposed to be conducted by it and to own
or lease and operate its Properties as now owned or leased by it.

               (H) PATENTS, TRADEMARKS, COPYRIGHTS AND LICENSES. Borrower owns
or possesses all the patents, trademarks, service marks, trade names, copyrights
and licenses necessary for the present and planned future conduct of its
business without any known conflict with the rights of others. All such patents,
trademarks, service marks, trade names, copyrights, licenses and other similar
rights are listed on EXHIBIT G attached hereto and made a part hereof. ---------

               (I) CAPITAL STRUCTURE. EXHIBIT H attached hereto and made a part
hereof states (i) the correct name of each of the Subsidiaries of Borrower, the
jurisdiction of incorporation and the percentage of its Voting Stock owned by
Borrower, (ii) the name of each of Borrower's corporate or joint venture
Affiliates and the nature of the affiliation, (iii) the number, nature and
holder of all outstanding Securities of Borrower and each Subsidiary of
Borrower, and (iv) the number of authorized, issued and treasury shares of
Borrower and each Subsidiary of Borrower. Borrower has good title to all of the
shares of stock it purports to own of each Subsidiary, free and clear in each
case of any Lien other than Permitted Liens. All such shares have been duly
issued and are fully paid and nonassessable. Except as provided in EXHIBITS H
and I attached hereto, there are not outstanding any options to purchase, or any
rights or warrants to subscribe for, or any commitments or agreements to issue
or sell, or any Securities or obligations convertible into, or any powers of
attorney relating to, shares of the capital stock of Borrower. Except as
provided in EXHIBITS H and I attached hereto, there are not outstanding any
agreements or instruments binding upon any of Borrower's shareholders relating
to the ownership of its shares of capital stock.

               (J) SOLVENT FINANCIAL CONDITION. Borrower is now and, after
giving effect to initial Loans to be made hereunder, at all times will be,
Solvent.

               (K) RESTRICTIONS. Borrower is not a party or subject to any
contract, agreement, or charter or other corporate restriction, which materially
and adversely affects its business or the use or ownership of any of its
Properties other than as set forth on EXHIBIT J attached hereto. Borrower is not
a party or subject to any contract or agreement which restricts its right or
ability to incur Indebtedness, other than as set forth on EXHIBIT J attached
hereto, none of which prohibit the execution of or compliance with this
Agreement by Borrower. Neither Borrower nor any of its Subsidiaries has agreed
or consented to cause or permit in the future (upon the happening of a
contingency or otherwise) any of its Property, whether now owned or hereafter
acquired, to be subject to a Lien that is not a Permitted Lien.

               (L) LITIGATION. Except as set forth on EXHIBIT K attached hereto
and made a part hereof, there are no actions, suits, proceedings or
investigations pending, or to the knowledge of Borrower, threatened, against or
affecting Borrower or any of its Subsidiaries, or the business, operations,
Properties, prospects, profits or condition of Borrower or any of its
Subsidiaries, in any court or before any governmental authority or arbitration
board or tribunal, and no action, suit, proceeding or investigation shown on
EXHIBIT K attached hereto, except as indicated on such EXHIBIT K, involves the
possibility of materially and adversely affecting the Properties, business,
prospects, profits or condition (financial or otherwise) of Borrower or the
ability of Borrower to perform this Agreement. Neither Borrower nor any of its
Subsidiaries is in default with respect to any order, writ, injunction,
judgment, decree or rule of any court, governmental authority or arbitration
board or tribunal.

               (M) TITLE TO PROPERTIES. Subject to the statutory right of the
MMS to approve the acquisition of an Offshore Platform and related oil and gas
Properties and the provisions of the Buy-Sell Agreements, Borrower and its
Subsidiaries each has good, indefeasible and marketable title to and fee simple
ownership of, or valid and subsisting leasehold interests in, all of its oil and
gas Properties and real Property, and good title to all of its other Property,
in each case, free and clear of all Liens except Permitted Liens. EXHIBITS D and
S attached hereto identifies all of the Offshore Platforms, other oil and gas
Properties and real Property leased or owned by Borrower and its Subsidiaries
and, if leased, identifies the lessor thereof.

               (N) FINANCIAL STATEMENTS; FISCAL YEAR. The Consolidated balance
sheet of Borrower and such other Persons described therein (including the
accounts of all Subsidiaries for the respective periods during which a
Subsidiary relationship existed) as of December 31, 1994, and the related
statements of income, changes in stockholder's equity, and changes in cash flow
for the periods ended on such dates, have been prepared in accordance with GAAP
(except for changes in application in which Borrower's independent certified
public accountants concur), and present fairly the financial positions of
Borrower and its Subsidiaries at such dates and the results of Borrower's
operations for such periods. Since December 31, 1994 there has been no material
change in the condition, financial or otherwise, of Borrower, its Subsidiaries
and such other Persons as shown on the Consolidated balance sheet as of such
date and no change in the aggregate value of Equipment and other Property owned
by Borrower or its Subsidiaries or such other Persons, except as otherwise
disclosed in the footnotes to such financial statements and changes in the
ordinary course of business, which individually or in the aggregate has not been
materially adverse. The fiscal year of Borrower and each of its Subsidiaries
ends on December 31 of each year.

               (O) FULL DISCLOSURE. The financial statements referred to in
SECTION 7.1(N), do not, nor does this Agreement or any other written statement
of Borrower to Lender (including, without limitation, Borrower's filings, if
any, with the Securities and Exchange Commission), contain any untrue statement
of a material fact or omit a material fact necessary to make the statements
contained therein or herein not misleading. There is no fact which Borrower has
failed to disclose to Lender in writing which materially affects adversely or,
so far as Borrower can now foresee, will materially affect adversely the
Properties, business, prospects, profits, or condition (financial or otherwise)
of Borrower or any of its Subsidiaries or the ability of Borrower or its
Subsidiaries to perform this Agreement.

               (P) ERISA. Except as disclosed in EXHIBIT L attached hereto,
there are no Pension Plans or Multiemployer Plans and no fact exists that could
result in any material liability (other than as disclosed on Borrower's
financial statements) to Borrower relating to any former Plan. No Reportable
Event has occurred with respect to any Pension Plan that is not a Multiemployer
Plan. No Prohibited Transaction has occurred. The PBGC has not instituted
proceedings to terminate any Pension Plan. No ERISA Affiliate nor any duly
appointed administrator of a Pension Plan has (i) incurred any liability to the
PBGC with respect to a Pension Plan other than for premiums not yet due and
payable, or (ii) instituted or intends to institute proceedings under Section
4041(c) of ERISA to terminate any Pension Plan, or (iii) instituted proceedings
to withdraw from any Pension Plan that is a Multiemployer Plan. No "accumulated
funding deficiency" within the meaning of Section 302(a)(2) of ERISA exists with
respect to any Pension Plan. No liability has been incurred by any ERISA
Affiliate which remains unsatisfied for any taxes or penalties, with respect to
any Plan that is not a Multiemployer Plan or, to the best of Borrower's
knowledge and belief, with respect to any Multiemployer Plan. No litigation is
pending or threatened concerning or involving any Plan. No amendment to any
Pension Plan has been adopted such that security is required to be given
pursuant to IRC Section 401(a)(29) and no lien exists under IRC Section 412(n)
with respect to any Plan. Except as shown on EXHIBIT L attached hereto with
respect to the date and using the assumptions described thereon, and to the best
of Borrower's knowledge and belief, no unfunded or unreserved liability exists
for benefits under any Plan that would have a material adverse effect. No ERISA
Affiliate contributes to, has contributed to, or is or has been obligated to
contribute to, any Multiemployer Plan. No ERISA Affiliate maintains any Plan
which provides benefits to an employee or the employee's dependents after the
employee terminates employment other than as required by law and no written or
oral representations have been made to any employee or former employee promising
or guaranteeing any employer payment or funding for the continuation of medical,
dental, or disability coverage beyond that legally required.

               (Q) TAXES. The federal tax identification numbers for Cal Dive
and ERT are 95-3409686 and 76-0413713, respectively. Borrower and its
Subsidiaries each has filed all federal, state and local tax returns and other
reports it is required by law to file and has paid, or made provision for the
payment of, all taxes, assessments, fees and other governmental charges that are
due and payable. The provision for taxes on the books of Borrower and its
Subsidiaries are adequate for all years not closed by applicable statutes, and
for its current fiscal year. There are no material unresolved questions or
claims concerning any tax liability of Borrower except as described in EXHIBIT M
attached hereto. None of the transactions contemplated hereby or under any
agreements referred to hereunder will result in any material tax liability for
Borrower or result in any other material adverse tax consequence for Borrower.
EXHIBIT N attached hereto contains an accurate list of all taxing authorities to
which Borrower and its Subsidiaries and their respective Properties are subject.
No Properties of Borrower or its Subsidiaries are or could become subject to any
Lien in favor of any such taxing authorities for nonpayment of taxes, except as
specified on EXHIBIT N attached hereto.

               (R) LABOR RELATIONS. Except as described on EXHIBIT O attached
hereto, neither Borrower nor any of its Subsidiaries is a party to any
collective bargaining agreement, and there are no material grievances, disputes
or controversies with any union or any other organization of Borrower's
employees, or threats of strikes, work stoppages or any asserted pending demands
for collective bargaining by any union or organization.

               (S) COMPLIANCE WITH LAWS. Except as disclosed on EXHIBIT P
attached hereto as to existing violations of Environmental Laws (the "EXISTING
ENVIRONMENTAL VIOLATIONS"), Borrower has duly complied with, and its Property,
business operations and leaseholds are in compliance in all material respects
with, the provisions of all federal, state and local laws, rules, regulations
orders, citations and notices applicable to Borrower, its Properties or the
conduct of its business, including, without limitation, OSHA, Environmental
Laws, the Securities Act of 1933, the Securities Exchange Act of 1934, the Fair
Labor Standards Act, laws relating to income, unemployment, payroll or social
security taxes and Plans under ERISA, the Flood Disaster Protection Act of 1973,
the Consumer Credit Protection Act, the Federal Trade Commission Act, statutes
creating and governing the Bureau of Alcohol, Tobacco and Firearms, and any and
all state statutes or pronouncements addressing, or related to, subjects the
same as or comparable to those covered by such enumerated federal statutes, and
there have been no citations, notices or orders of noncompliance issued to
Borrower or any of its Subsidiaries under any such law, rule or regulation.

               (T) SURETY OBLIGATIONS. Except as described in EXHIBIT Q attached
hereto, Borrower is not obligated as surety or indemnitor under any surety or
similar bond or other contract issued or entered into any agreement to assure
payment, performance or completion of performance of any undertaking or
obligation of any Person.

               (U) NO DEFAULTS. No event has occurred and no condition exists
which would, upon the execution and delivery of this Agreement or Borrower's
performance hereunder, constitute a Default or an Event of Default. Neither
Borrower nor any of its Subsidiaries is in default, and no event has occurred
and no condition exists which constitutes, or which with the passage of time or
the giving of notice or both would constitute, a default in the payment of any
Indebtedness to any Person for Money Borrowed.

               (V) BROKERS. There are no claims for brokerage commissions,
finder's fees or investment banking fees in connection with the transactions
contemplated by this Agreement.

               (W) BUSINESS LOCATIONS; AGENT FOR PROCESS. During the preceding
three year period, Borrower has had no office, place of business or agent for
service of process located in any state or county other than as shown on EXHIBIT
D attached hereto.

               (X) TRADE RELATIONS. There exists no actual or threatened
termination, cancellation or limitation of, or any modification or change in,
the business relationship between Borrower and any customer or any group of
customers whose purchases individually or in the aggregate are material to the
business of Borrower, or with any material supplier, and there exists no present
condition or state of facts or circumstances which would materially affect
adversely Borrower or prevent Borrower from conducting such business after the
consummation of the transaction contemplated by this Agreement in substantially
the same manner in which it has heretofore been conducted.

               (Y) LEASES. EXHIBIT R attached hereto is a complete listing of
all capitalized leases of Borrower and EXHIBIT S attached hereto is a complete
listing of all operating leases of Borrower.


               (Z) INVESTMENT COMPANY ACT. Borrower is not an "investment
company" or a company "controlled" by an "investment company", within the
meaning of the Investment Company Act of 1940, as amended.

               (AA) OSHA AND ENVIRONMENTAL COMPLIANCE.

               (i) Except for the Existing Environmental Violations, Borrower is
in compliance with, and its facilities, business, operations, assets, Property,
leaseholds, Offshore Platforms and Equipment are in compliance in all material
respects with, the provisions of OSHA, the Resource Conservation and Recovery
Act, all Environmental Laws and all permits issued to Borrower under any
Environmental Laws; there have been no and are not now any outstanding

Borrower aware of any potential or threatening citations, notices or orders of
noncompliance that may be issued to Borrower or relating to its business,
assets, Property, leaseholds, Offshore Platforms or Equipment under such laws,
rules or regulations.

                      (ii) Borrower has been issued all required federal, state

Environmental Laws.

                      (iii) Except for the Existing Environmental Violations,

items, substances or chemicals used or useful in the ordinary course of business
by Borrower (collectively the "LAWFUL SUBSTANCES")); and (d) no Hazardous
Substances are present on the Real Property in violation of any Environmental
Laws.

        7.2. REAFFIRMATION. Each request for a Loan made by Borrower pursuant to
this Agreement or any of the other Loan Documents shall constitute (i) an
automatic representation and warranty by Borrower to Lender that there does not
then exist any Default or Event of Default unless otherwise disclosed to Lender
in writing and (ii) a reaffirmation as of the date of said request that all of
the representations and warranties of Borrower contained in this Agreement and
the other Loan Documents are true in all material respects except for any
changes in the nature of Borrower's business or operations that would render the
information contained in any exhibit attached hereto either inaccurate or
incomplete, so long as Lender has consented to such changes in writing or such
changes are expressly permitted by this Agreement.

        7.3. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. Borrower covenants,
warrants and represents to Lender that all representations and warranties of
Borrower contained in this Agreement or any of the other Loan Documents shall be
true at the time of Borrower's execution of this Agreement and the other Loan

Lender and the parties thereto and the closing of the transactions described
therein or related thereto until four (4) years and one (1) day after all of the
Obligations have been paid in full.

                 SECTION 8. COVENANTS AND CONTINUING AGREEMENTS

               8.1. AFFIRMATIVE COVENANTS. During the term of this Agreement,
and thereafter for so long as there are any Obligations to Lender, Borrower
covenants that, unless otherwise consented to by Lender in writing, it shall:

               (A) TAXES AND LIENS. Pay and discharge, and cause each Subsidiary
to pay and discharge, all taxes, assessments and governmental charges upon it,
its income and Properties as and when such taxes, assessments and charges are
due and payable (and, if requested by Lender, provide Lender with proof that
Borrower or such Subsidiary has done so), except and to the extent only that
such taxes, assessments and charges are being actively contested in good faith
and by appropriate proceedings, Borrower maintains adequate reserves on its
books therefor and the nonpayment of such taxes, assessments and charges does
not result in a Lien upon any Properties or Borrower other than a Permitted
Lien. Borrower shall also pay and discharge any lawful claims which, if unpaid,
might become a Lien against any of Borrower's Properties, except for Permitted
Liens. Borrower shall also make timely payment or deposit of all FICA payments
and withholding taxes required of it by the applicable laws, and will, upon
request, furnish Lender with proof satisfactory of it that Borrower has made
such payments or deposits.

               (B) TAX RETURNS. File, and cause each Subsidiary to file, all
federal, state and local tax returns and other reports Borrower or such
Subsidiary is required by law to file and maintain adequate reserves for the
payment of all taxes, assessments, governmental charges, and levies imposed upon
it, its income, or its profits, or upon any Property belonging to it.

               (C) PAYMENT OF BANK CHARGES. Pay to Lender, on demand, any and
all reasonable and customary fees, costs or expenses which Lender pays to a bank
or other similar institution arising out of or in connection with (i) the
forwarding to Borrower or any other Person on behalf of Borrower, by Lender
proceeds of loans made by Lender to Borrower pursuant to this Agreement and (ii)
the depositing for collection, by Lender of any check or item of payment
received or delivered to Lender on account of the Obligations.

               (D) BUSINESS AND EXISTENCE. Preserve and maintain, and cause each
Subsidiary to preserve and maintain, its separate corporate existence and all
rights, privileges, and franchises in connection therewith, and maintain, and
cause each Subsidiary to maintain, its qualification and good standing in all
states in which such qualification is necessary.

               (E) MAINTAIN PROPERTIES. Maintain, and cause each Subsidiary to
maintain, its Properties in adequate operating condition and make, and cause
each Subsidiary to make, all necessary renewals, repairs, replacements,
additions and improvements thereto.


               (F) COMPLIANCE WITH LAWS AND REMEDIATION OF EXISTING
ENVIRONMENTAL VIOLATIONS. (i) Except for the Existing Environmental Violations
and the storage of the Lawful Substances, comply, and cause each Subsidiary to
comply, with all laws, ordinances, governmental rules and regulations to which
it is subject, including, without limitation, all Environmental Laws, and obtain
and keep in force any and all licenses, permits, franchises, or other
governmental authorizations necessary to the ownership or lease of its
Properties or to the conduct and operation of its business, which violation or
failure to obtain might materially and adversely affect the business, prospects,
profits, Properties, or condition (financial or otherwise) of Borrower.

Service pursuant to ERISA, and the regulations promulgated thereunder, in
connection with each of its Plans that is not a Multiemployer Plan for each Plan
year, (iii) notify Lender prior to any request for a waiver of the funding
requirements of IRC Section 412 or the commencement of any distress termination
pursuant to ERISA Section 4041(c), (iv) notify Lender immediately of any
Reportable Event, Prohibited Transaction, and of any fact arising in connection
with any of its Plans that is not a Multiemployer Plan, which might constitute
grounds for termination thereof by the PBGC or for the appointment by the
appropriate United States District Court of a trustee to administer such Plan,
together with a statement, if requested by Lender, as to the reason therefor and
the action, if any, proposed to be taken with respect thereto, (v) notify Lender
immediately of any event which is likely to give rise to an assertion of
withdrawal liability in connection with a Multiemployer Plan, and (vi) furnish
to Lender, promptly upon Lender's request therefor, such additional information
concerning any Plan as may be reasonably requested.

               (H) BUSINESS RECORDS. Keep, and cause each Subsidiary to keep,
adequate records and books of account with respect to its business activities in
which proper entries are made in accordance with GAAP reflecting all its
financial transactions.

be reasonably requested, but only during normal business hours, to visit and
inspect the Properties of Borrower, inspect and make extracts from its books and
records, and discuss with its officers, its employees and its independent
accountants, Borrower's business, assets, liabilities, financial condition,
business prospects and results of operations; PROVIDED, HOWEVER, if a Default or
Event of Default exists, Lender shall not be required to give notice to Borrower
prior to inspection or visitation by Lender of Borrower's Properties.

               (J) FINANCIAL STATEMENTS. Cause to be prepared and furnished to
Lender the following (all to be kept and prepared in accordance with GAAP

consolidated financial position and results of operations of Borrower and its
Subsidiaries for such month and period subject only to changes from audit and
year-end adjustments and except that such statements need not contain notes;

                       (iii) promptly after the sending or filing thereof, as
the case may be, copies of any proxy statements, financial statements or reports

                       (iv) such other data and information (financial and
otherwise) as Lender, from time to time, may reasonably request, bearing upon or
related to the Collateral, Borrower's financial condition or results of
operations, including, without limitation, federal income tax returns of

the financial statements of Borrower and its Subsidiaries performed in
connection with their examination of said financial statements, they are not
aware of any Default or Event of Default, or, if they are aware of such Default
or Event of Default, specifying the nature thereof. Concurrently with the

               (K) NOTICES TO LENDER. Notify Lender in writing: (i) promptly
after Borrower's learning thereof, of the commencement of any litigation
affecting Borrower or any of its Properties, whether or not the claim is
considered by Borrower to be covered by insurance, and of the institution of any

federal, state or local agency which may materially and adversely affect
Borrower's operations, financial condition, Properties or business or Lender's

               (L) LANDLORD AND STORAGE AGREEMENTS. Provide Lender with copies

               (M) SUBORDINATIONS. Except for Permitted Purchase Money
Indebtedness, provide Lender with a debt subordination agreement, in form and
substance satisfactory to Lender, executed by Borrower and any Person who is an
officer, director or Affiliate of Borrower to whom Borrower is or hereafter

all of such Indebtedness and any future advances thereon to the full and final
payment and performance of the Obligations. For purposes of this SECTION 8.1(M),
the term "Affiliate" shall include First Reserve.

               (N) FURTHER ASSURANCES. At Lender's request, promptly execute or
cause to be executed and deliver to Lender any and all documents, instruments
and agreements deemed necessary by Lender to give effect to or carry out the
terms or intent of this Agreement or any of the other Loan Documents. Without
limiting the generality of the foregoing, if any of the Accounts, the face value
of which exceeds One Thousand Dollars ($1,000), arises out of a contract with
the United States of America, or any department, agency, subdivision or
instrumentality thereof, Borrower shall promptly notify Lender thereof in
writing and shall execute any instruments and take any other action required or
requested by Lender to comply with the provisions of the Federal Assignment of
Claims Act.

               (O) TAX CERTIFICATE. Within ninety (90) days after the end of
each fiscal year of Borrower, or more frequently if requested by Lender, cause

               (R) MARINE VESSEL MAINTENANCE. Keep adequate records with respect
to maintenance of marine vessels which detail drydocking, machinery overhauls
and maintenance history for each marine vessel owned by Borrower.

               (S) PROJECTIONS. As soon as available, and in any event no later

               (U)    ENVIRONMENTAL MATTERS.

                       (i) Ensure that the Real Property remains in compliance
with all Environmental Laws where the failure to do so would have a material
adverse effect on its business, condition (financial or otherwise), operations,
prospects or Properties, and it will not place or permit to be placed any
Hazardous Substance on any Real Property except as not prohibited by applicable
law or appropriate governmental authorities. Notwithstanding the foregoing,
Lender and Borrower recognize the Existing Environmental Violations and the
storing of the Lawful Substances and Borrower hereby agrees to ensure that all
Existing Environmental Violations are remediated in a diligent and timely
manner.

                       (ii) Establish and maintain an adequate system to assure
and monitor continued compliance with all applicable Environmental Laws
appropriate to the nature of Borrower's business.

                       (iii) (a) employ in connection with its use of the Real
Property appropriate technology necessary to maintain compliance with any
applicable Environmental Laws, and (b) dispose of any and all Hazardous
Substance generated at the Real Property only at facilities and with carriers
that maintain valid permits under the Resource Conservation and Recovery Act and
any other applicable Environmental Laws. Borrower shall obtain certificates of
disposal, such as hazardous waste manifest receipts, from all treatment,
transport, storage or disposal facilities or operators in connection with the
transport or disposal of any Hazardous Substance generated at the Real Property.

                       (iv) In the event the Borrower obtains, gives or receives
notice of any Release or threat of Release of a reportable quantity of any
Hazardous Substances at the Real Property (any such event being hereinafter
referred to as a "HAZARDOUS DISCHARGE") or receives any notice of violation,
request for information or notification that it is potentially responsible for
investigation or cleanup of environmental conditions, demand letter or
complaint, order, citation, or other written notice with regard to any Hazardous
Discharge or violation of Environmental Laws (any of the foregoing is referred
to herein as an "ENVIRONMENTAL COMPLAINT") from any Person or entity, including
any state or local agency responsible in whole or in part for environmental
matters in the state in which the Real Property is located or the United States
Environmental Protection Agency (any such person or entity hereinafter the
"AUTHORITY"), then the Borrower shall, within five (5) Business Days, give
written notice of same to the Lender setting forth facts and circumstances
giving rise to the Hazardous Discharge or Environmental Complaint. Such notice
is not intended to create nor shall it create any obligation upon Lender with
respect thereto.

                       (v) Promptly forward to Lender copies of any request for
information, notification of potential liability, demand letter relating to
potential responsibility with respect to the investigation or cleanup of
Hazardous Substances at any other site owned, operated or used by Borrower to
dispose of Hazardous Substances and shall continue to forward copies of
correspondence between Borrower and the Authority regarding such claims to the
Lender until the claim is settled. The Borrower shall promptly forward to the
Lender copies of all documents and reports concerning a Hazardous Discharge that
the Borrower is required to file under any Environmental Laws. Such information
is to be provided solely to allow the Lender to protect Lender's security
interest in the Collateral and is not intended to create nor shall it create any
obligation upon Lender with respect thereto.

                       (vi) Respond promptly to any Hazardous Discharge or
Environmental Complaint and take all necessary action in order to safeguard the
health of any Person and to avoid subjecting the Collateral or Real Property to
any Lien. Borrower shall be deemed to be taking all necessary action only if,
and for so long as, the execution or enforcement of an Environmental Complaint
is, and continues to be, effectively stayed and the Borrower maintains adequate
reserves therefore, which are properly reflected on Borrower's Consolidated
Financial Statements, the validity and amount of the claims secured thereby are
being actively contested in good faith and by appropriate lawful proceedings,
and such Liens do not, in the aggregate, materially detract from the value of
the Property of Borrower or materially impair the use thereof in the operation
of Borrower's business. If Borrower shall fail to so respond to any Hazardous
Discharge or Environmental Complaint or Borrower shall fail to comply with any
of the requirements of any Environmental Laws where the failure to do so would
have a material adverse effect on its business, condition (financial or
otherwise), operations, prospects or Properties, Lender may, but without the
obligation to do so, for the sole purpose of protecting Lender's interest in
Collateral: (a) give such notices or (b) enter onto the Real Property (or
authorize third parties to enter onto the Real Property) and take such actions
as Lender (or such third parties as directed by the Lender) deem reasonably
necessary or advisable, to clean up, remove, mitigate or otherwise deal with any
such Hazardous Discharge or Environmental Complaint. All reasonable costs and
expenses incurred by Lender (or such third parties) in the exercise of any such
rights, including any sums paid in connection with any judicial or
administrative investigation or proceedings, fines and penalties, together with
interest thereon from the date expended at the Applicable Annual Rate for Base
Rate Loans shall be paid upon demand by the Borrower, and until paid shall be
added to and become a part of the Obligations secured by the Liens created by
the terms of this Agreement or any other agreement between Lender and Borrower.

                      (vii) Promptly upon the written request of the Lender, in
connection with any Hazardous Discharge or Environmental Complaint as described
in CLAUSE (VI) immediately preceding, provide to Lender, at the Borrower's
expense, with an environmental site assessment or environmental
audit report prepared by an environmental engineering firm acceptable to Lender
to assess with a reasonable degree of certainty the existence of a Hazardous
Discharge and the potential costs in connection with abatement, cleanup and
removal of any Hazardous Substances found on, under, at or within the Real
Property. Any report or investigation of such Hazardous Discharge proposed and
acceptable to an appropriate Authority that is charged to oversee the clean-up
of such Hazardous Discharge shall be acceptable to the Lender.

                       (viii) Defend and indemnify Lender and hold Lender, and
its respective employees, agents, directors and officers harmless from and
against all loss, liability, damage and expense, claims, costs, fines and
penalties, including attorney's fees, suffered or incurred by Lender under or on
account of any Environmental Laws, including, without limitation, the assertion
of any Lien thereunder, with respect to any Hazardous Discharge, the presence of
any Hazardous Substances affecting its business and operations or the Real
Property, whether or not the same originates or emerges from the Real Property
or any contiguous real estate, including any loss of value of the Real Property
as a result of the foregoing. Borrower's obligations under this SECTION 8.1(U)
shall arise upon the discovery of the presence of any Hazardous Substances at
the Real Property or Borrower's use of Hazardous Substances in its business and
operations, whether or not any federal, state, or local environmental agency has
taken or threatened any action in connection with the presence of any Hazardous
Substances. Borrower's obligation and the indemnifications hereunder shall
survive the termination of this Agreement.

                       (ix) For purposes of SECTION 7.1(AA), 8.1(U) and 8.2(AA),
all references to "REAL PROPERTY" shall be deemed to be all of Borrower's right,
title and interest in and to all leased and owned premises, including, without
limitation, the Offshore Platforms.


               (V) KEY MAN LIFE INSURANCE. Maintain and pay for life insurance
on each of Gerald G. Reuhl and Owen E. Kratz in a minimum amount of Six Million
Dollars ($6,000,000) per insured with insurance companies acceptable to Lender,
which life insurance policies shall be assigned to Lender within sixty (60) days
from the Closing Date pursuant to an assignment agreement in form and substance
satisfactory to Lender and the insurance company issuing such life insurance
policy.

               (W) EXCESS AVAILABILITY. Maintain Excess Availability of (i) no
less than Two Million Dollars ($2,000,000) immediately prior to and after giving
effect to the acquisition of any oil and gas Properties by ERT, and (ii) no less

effect to the acquisition (excluding a lease arrangement) and deployment of both
a barge and a dive support vessel by Cal Dive.

                       8.2. NEGATIVE COVENANTS. During the term of this
Agreement, and thereafter for so long as there are any Obligations to Lender,

adequate by Borrower and its independent public accountants; (iii) Obligations
to pay Rentals permitted by SECTION 8.2(U); (iv) Permitted Purchase Money

any Affiliate or First Reserve, except (i) transactions in the ordinary course
of and pursuant to the reasonable requirements of Borrower's or such
Subsidiary's business and upon fair and reasonable terms which are fully
disclosed to Lender and are no less favorable to Borrower than would obtain in a
comparable arm's length transaction with a Person not an Affiliate or
stockholder of Borrower or such Subsidiary, (ii) transactions contemplated by
the Shareholders Agreement, in effect on the Closing Date, and (iii) equity
contributions to Borrower by First Reserve on terms and conditions acceptable to

enter into any transaction, or permit any Subsidiary to enter into any

adversely affect the Collateral or Borrower's ability to repay the Obligations

any change or modification of any kind or nature with respect to any Account,

Schedules of Accounts submitted to Lender pursuant to SECTION 5.2.

                       (G) GUARANTIES. Except as described on EXHIBIT V attached

the payment thereof is not at the time required and only if such Liens are
junior to the Liens in favor of Lender, or if, and for so long as, the execution
or other enforcement of such Liens is, and continues to be, effectively stayed,
the validity and amount of the claims secured thereby are being actively
contested in good faith and by appropriate lawful proceedings, and such Liens do
not, in the aggregate, materially detract from the value of the Property of
Borrower or materially impair the use thereof in the operation of Borrower's
business; (iv) Liens resulting from deposits made in the ordinary course of
business in connection with workmen's compensation, unemployment insurance,
social security and other like laws; (v) attachment, judgment and other similar
non-tax Liens arising in connection with court proceedings, but only if and for

occurrence of an Event of Default as above provided, all or any portion of the
Obligations due or to become due from Borrower to Lender (whether under this
Agreement, or any of the other Loan Documents or otherwise) shall, at Lender's
option (or, in the case of an Event of Default under SECTION 10.1(J) hereof,
immediately upon the occurrence thereof), become at once due and payable without
presentment, demand, protest, notice of dishonor, notice of default, notice of
intent to accelerate, notice of acceleration, or any other notice whatsoever,
and Borrower shall forthwith pay to Lender, in addition to any and all sums and
charges due, the entire principal of and interest accrued on the Obligations.

               10.3. REMEDIES. Upon and after the occurrence of an Event of
Default, Lender shall have and may exercise from time to time the following
rights and remedies:

               (A) All of the rights and remedies of a secured party under the
Code, the 1989 Act or under other applicable law, and all other legal and
equitable rights to which Lender may be entitled, all of which rights and
remedies shall be cumulative, and none of which shall be exclusive, and shall be
in addition to any other rights or remedies contained in this Agreement or any
of the other Loan Documents.

               (B) The right to take immediate possession of the Collateral, and
(i) to require Borrower to assemble the Collateral, at Borrower's expense, and
make it available to Lender at a place designated by Lender which is reasonably
convenient to both parties, and (ii) to enter any of the premises of Borrower or
wherever any of the Collateral shall be located, and to keep and store the same
on said premises until sold (and if said premises be the Property of Borrower,
Borrower agrees not to charge Lender for storage thereof).

               (C) The right to sell or otherwise dispose of all or any
Inventory or Equipment in its then condition, or after any further manufacturing
or processing thereof, at public or private sale or sales, with such notice as
may be required by law, in lots or in bulk, for cash or on credit, all as
Lender, in its discretion, may deem advisable. Borrower agrees that ten days
written notice to Borrower of any public or private sale or other disposition of
such Collateral shall be reasonable notice thereof, and such sale shall be at
such locations as Lender may designate in said notice. Lender shall have the
right to conduct such sales on Borrower's premises, without charge therefor, and
such sales may be adjourned from time to time in accordance with applicable law.
Lender shall have the right to sell, lease or otherwise dispose of such
Collateral, or any part thereof, for cash, credit or any combination thereof,
and Lender may purchase all or any part of such Collateral at public or, if
permitted by law, private sale and, in lieu of actual payment of such purchase
price, may set off the amount of such price against the Obligations.

               (D) Lender is hereby granted a license or other right to use,
without charge, Borrower's labels, patents, copyrights, rights of use of any
name, trade secrets, trade names, trademarks and advertising matter, or any
Property of a similar nature, as it pertains to the Collateral, in advertising
for sale and selling any Collateral and Borrower's rights under all licenses and
all franchise agreements shall inure to Lender's benefit.

               (E) The proceeds realized from the sale of any Collateral may be
applied, after allowing two Business Days for collection, first to the costs,
expenses and reasonable attorneys' fees incurred by Lender in collecting the
Obligations, in enforcing the rights of Lender under the Loan Documents and in
collecting, retaking, completing, protecting, removing, storing, advertising for
sale, selling and delivery any of the Collateral; secondly, to interest due upon
any of the Obligations; and thirdly, to the principal of the Obligations.

               (F) With respect to the face amount of all LC Guaranties and
Letters of Credit issued by Lender or Bank Lender may, at its option, require
Borrower to deposit with Lender funds equal to such face amount, and if Borrower
fails to promptly make such deposit, Lender may advance such amount as a
Revolving Credit Loan (whether or not such advance would cause the outstanding
balance of Revolving Credit Loans to exceed the Borrowing Base). Any such
deposit or advance shall be held by Lender as a reserve to fund future payments
on such LC Guaranties and future drawings against such Letters of Credit. At
such time as all LC Guaranties have been paid or terminated and all Letters of
Credit issued by Lender or Bank have been drawn upon or expired, any amounts
remaining in such reserve shall be applied against any outstanding Obligations,
or to the extent all Obligations have been indefeasibly paid in full, returned
to Borrower.

        10.4. REMEDIES CUMULATIVE; NO WAIVER. All covenants, conditions,
provisions, warranties, guaranties, indemnities, and other undertakings of
Borrower contained in this Agreement and the other Loan Documents, or in any
document referred to herein or contained in any agreement supplementary hereto
or in any schedule or in any Guaranty Agreement given to Lender or contained in
any other agreement between Lender and Borrower, heretofore, concurrently, or
hereafter entered into, shall be deemed cumulative to and not in derogation or
substitution of any of the terms, covenants, conditions, or agreements of
Borrower herein contained or of any of the other rights or remedies of Lender as
provided by any applicable law or in equity. The failure or delay of Lender to
exercise or enforce any rights, Liens, powers, or remedies hereunder or under
any of the aforesaid agreements or other documents or security or Collateral or
other rights or remedies shall not operate as a waiver of such Liens, rights,
powers and remedies, but all such Liens, rights, powers, and remedies shall
continue in full force and effect until all Loans and all other Obligations
owing or to become owing from Borrower to Lender shall have been fully
satisfied, and all Liens, rights, powers, and remedies herein provided for are
cumulative and none are exclusive.

                                  SECTION 11.  MISCELLANEOUS

        11.1. POWER OF ATTORNEY. Borrower hereby irrevocably designates, makes,
constitutes and appoints Lender (and all Persons designated by Lender) as
Borrower's true and lawful attorney (and agent-in-fact) and Lender, or Lender's
agent, may, in either Borrower's or Lender's name, but at the cost and expense
of Borrower:

               (A) At such time or times hereafter as Lender or said agent may
determine and after notice to Borrower, endorse Borrower's name on any checks,
notes, acceptances, drafts, money orders or any other evidence of payment or
proceeds of the Collateral which come into the possession of Lender or under
Lender's control; and

               (B) At such time or times upon or after the occurrence of an
Event of Default as Lender or its agent may determine: (i) demand payment of the
Accounts from the Account Debtors, enforce payment of the Accounts by legal
proceedings or otherwise, and generally exercise all of Borrower's rights and
remedies with respect to the collection of the Accounts; (ii) settle, adjust,
compromise, discharge or release any of the Accounts or other Collateral or any
legal proceedings brought to collect any of the Accounts or other Collateral;
(iii) sell or assign any of the Accounts and other Collateral upon such terms,
for such amounts and at such time or times as Lender deems advisable; (iv) take
control, in any manner, of any item of payment or proceeds relating to any
Collateral; (v) prepare, file and sign Borrower's name to a proof of claim in
bankruptcy or similar document against any Account Debtor or to any notice of
lien, assignment or satisfaction of lien or similar document in connection with
any of the Collateral; (vi) receive, open and dispose of all mail addressed to
Borrower and to notify postal authorities to change the address for delivery
thereof to such address as Lender may designate; (vii) endorse the name of
Borrower upon any of the items of payment or proceeds relating to any Collateral
and deposit the same to the account of Lender on account of the Obligations;
(viii) endorse the name of Borrower upon any chattel paper, document,
instrument, invoice, freight bill, bill of lading or similar document or
agreement relating to the Accounts, Inventory and any other Collateral; (ix) use
Borrower's stationery and sign the name of Borrower to verifications of the
Accounts and notices thereof to Account Debtors; (x) use the information
recorded on or contained in any data processing equipment and computer hardware
and software relating to the Accounts, Inventory, Equipment and any other
Collateral and to which Borrower has access; (xi) make and adjust claims under
policies of insurance; and (xii) do all other acts and things necessary, in
Lender's determination, to fulfill Borrower's obligations under this Agreement.

        11.2. INDEMNITY. Borrower hereby indemnifies, holds harmless, and shall
defend Lender and its directors, officers, agents, counsel and employees
("INDEMNIFIED PERSONS") from and against any and all losses, liabilities,
damages, costs, expenses, suits, actions and proceedings ("LOSSES") ever
suffered or incurred by any Indemnified Person arising out of or relating to
this Agreement or any other transaction contemplated hereby, including, without
limitation, any Losses caused by the negligence of such Indemnified Person, but
not including any Losses caused by the gross negligence or willful misconduct of
such Indemnified Person, and Borrower shall reimburse Lender and each other
Indemnified Person for any expenses (including in connection with the
investigation of, preparation for or defense of any actual or threatened claim,
action or proceeding arising therefrom, including any such costs of responding
to discovery requests or subpoenas, regardless of whether Lender or such other
Indemnified Person is a party thereto). Without limiting the generality of the
foregoing, this indemnity shall extend to any claims asserted against Lender or
any other Indemnified Person by any Person under any Environmental Laws or
similar laws by reason of Borrower's or any other Person's failure to comply
with laws applicable to solid or hazardous waste materials or other toxic
substances. Borrower may select counsel with respect to any Losses; PROVIDED,
HOWEVER, each Indemnified Person shall have the right to monitor the progress of
any claims, suits and administrative proceedings defended by Borrower hereunder
with counsel of such Indemnified Person's choice, or conduct its defense through
counsel of such Indemnified Person's choice, in the event that (i) such
Indemnified Person determines in good faith that the conduct of its defense by
Borrower could be materially prejudicial to such Indemnified Person's interests
or that other reasonable grounds exist which demonstrate a lack of effectiveness
or high level of quality in the conduct of such defense by Borrower, and (ii)
prior to retaining such counsel for such purpose, such Indemnified Person shall
consult with Borrower and shall attempt in good faith to agree upon counsel to
conduct the defense on behalf of Borrower and such Indemnified Person, and in
each case the fees and disbursements of such counsel shall be paid by Borrower;
PROVIDED, HOWEVER, that if such mutual agreement is not reached within a
reasonable time on selecting counsel, then such Indemnified Person may retain
its own counsel at Borrower's expense. Notwithstanding any contrary provision of
this Agreement, the obligation of Borrower under this SECTION 11.2 shall survive
the payment in full of the Obligations and the termination of this Agreement.

        11.3. MODIFICATION OF AGREEMENT. This Agreement and the other Loan
Documents may not be modified, altered or amended, except by an agreement in
writing signed by Borrower and Lender.

        11.4. REIMBURSEMENT OF EXPENSES. Without limiting Borrower's obligations
for payment of expenses as provided elsewhere in this Agreement or in any other
Loan Document, if, at any time or times prior or subsequent to the date hereof,
regardless of whether or not an Event of Default then exists or any of the
transactions contemplated hereunder are concluded, Lender incurs any
out-of-pocket expenses (including, without limitation, the fees and expenses of
Lender's attorneys if Lender retains legal counsel) in connection with: (A) the
negotiation and preparation of the Loan Documents, any amendment or modification
of any Loan Documents; or (B) the administration of the Loan Documents and the
transactions contemplated thereby; (C) any litigation, contest, dispute, suit,
proceeding or action (whether instituted by Lender, Borrower or any other
Person) in any way relating to the Collateral, any Loan Documents, Lender's and
Borrower's relationship, or Borrower's affairs; (D) any attempt to enforce any
rights of Lender against Borrower or any other Person which may be obligated to
Lender by virtue of any Loan Documents, including, without limitation, the
Account Debtors; (E) the exercise or enforcement of any rights, remedies or
privileges of Lender under the Loan Documents or applicable law; (F) the
analysis of information received in connection with any Loan Documents; (G) the
audit or appraisal of any Collateral or Borrower's books and records; (H) the
granting of any consents or waivers requested in connection with the Loan
Documents; (I) the collection of any Obligations; or (J) any attempt to inspect,
verify, protect, preserve, restore, collect, sell, liquidate or otherwise
dispose of or realize upon the Collateral; then, in any such event, all
expenses, costs, charges and other fees incurred by Lender or its attorneys or
relating to any of the events or actions described in this SECTION 11.4 shall be
payable, on demand, by Borrower to Lender, and shall be additional Obligations
hereunder secured by the Collateral. Without limiting the generality of the
foregoing, such expenses, costs, charges and fees may include: recording costs;
appraisal costs; accountants' fees, costs and expenses; court costs and
expenses; photocopying and duplicating expenses; court reporter fees, costs and
expenses; attorney and paralegal fees, costs and expenses; long distance
telephone charges; air express charges; telegram and facsimile charges; wire
transfer fees; secretarial overtime charges; and expenses for travel, lodging
and food. Additionally, if any taxes (excluding taxes imposed upon or measured
by the net income of Lender) shall be payable on account of the execution or
delivery of any of the Loan Documents, or the creation of any of the Obligations
hereunder, by reason of any existing or hereafter enacted federal or state
statute, Borrower will pay all such taxes, including, but not limited to, any
interest and penalties thereon, and will indemnify and hold Lender harmless from
and against liability in connection therewith.

        11.5. INDULGENCES NOT WAIVERS. Lender's failure, at any time or times
hereafter, to require strict performance by Borrower of any provision of this
Agreement shall not waive, affect or diminish any right of Lender thereafter to
demand strict compliance and performance therewith. Any suspension or waiver by
Lender of an Event of Default by Borrower under this Agreement or any of the
other Loan Documents shall not suspend, waive or affect any other Event of
Default by Borrower under this Agreement or any of the other Loan Documents,
whether the same is prior or subsequent thereto and whether of the same or of a
different type. None of the undertakings, agreements, warranties, covenants and
representations of Borrower contained in this Agreement or any of the other Loan
Documents and no Event of Default by Borrower under this Agreement or any of the
other Loan Documents shall be deemed to have been suspended or waived by Lender,
unless such suspension or waiver is by an instrument in writing specifying such
suspension or waiver and is signed by a duly authorized representative of Lender
and directed to Borrower.

        11.6. SEVERABILITY. Wherever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating the remainder of
such provision or the remaining provisions of this Agreement.

        11.7. SUCCESSORS AND ASSIGNS. This Agreement and the other Loan
Documents shall be binding upon and inure to the benefit of the successors and
assigns of Borrower and Lender; PROVIDED, HOWEVER, that Borrower may not sell,
assign or transfer any interest in this Agreement or any other Loan Document, or
any portion thereof, including, without limitation, Borrower's rights, title,
interests, remedies, powers and duties hereunder or thereunder. Any purported
assignment by Borrower in violation of this SECTION 11.7 shall be void, without
Lender's prior written consent. Borrower hereby consents to Lender's sale,
assignment, transfer or of the disposition, at any time or times hereafter, of
this Agreement, any other Loan Document, or any other Obligations, or of any
portion hereof or thereof, including, without limitation, Lender's rights,
title, interests, remedies, powers, and duties hereunder or thereunder,
PROVIDED, HOWEVER, (a) no such sale, assignment, transfer or disposition may be
made to any supplier, customer or competitor of Borrower unless such Person is
an institutional investor or investment firm, and (b) Lender shall not sell any
participation in this Agreement, any other Loan Documents or any of the
Obligations without Borrower's prior written consent. In the case of an
assignment, the assignee shall have, to the extent of such assignment, the same
rights, benefits and obligations as it would have if it were the original
"Lender" hereunder and Lender shall be relieved of all obligations hereunder
upon any such assignment. In the case of a participation, Lender shall remain
solely responsible to Borrower for the performance of its obligations hereunder
and Borrower shall continue to deal solely and directly with Lender in
connection with Lender's rights and obligations under this Agreement. Without
limiting the foregoing, Borrower hereby consents to Lender's sale and assignment
of this Agreement, the other Loan Documents and the Obligations, including,
without limitation, Lender's rights, title, interests, remedies, powers and
duties hereunder, to Fleet Financial Group, or a Subsidiary thereof, and agrees
and acknowledges that such assignee shall have all rights, benefits and
obligations as its would have if it were the original "Lender" hereunder.

        11.8. CUMULATIVE EFFECT; CONFLICT OF TERMS. The provisions of the Other
Agreements and the Security Documents are hereby made cumulative with the
provisions of this Agreement. Except as otherwise provided in SECTION 3.6 and
except as otherwise provided in any of the other Loan Documents by specific
reference to the applicable provision of this Agreement, if any provision
contained in this Agreement is in direct conflict with, or inconsistent with,
any provision in any of the other Loan Documents, the provision contained in
this Agreement shall govern and control.

        11.9. EXECUTION IN COUNTERPARTS. This Agreement may be executed in any
number of counterparts and by different parties hereto in separate counterparts,

                            CONTINGENCY RESERVE TERMS

                     Calculation of the Contingency Reserve

        PURPOSE: A Contingency Reserve will be established on the A/R ("01")
line at any time Excess Availability is less than $2,000,000 to serve as a guard
against potential priming liens on the Collateral. The approval of the loan
transaction with Cal Dive and ERT was subject to the establishment of "triggers"
signaling the evaluation and adjustment of the Contingency Reserve.

ACCOUNTS RECEIVABLE: - The calculation of the exposure is quite involved,
therefore triggers have been approved whereby potentially diluting items are to
be reviewed against benchmarks monthly:

a) should Excess Availability exceed or equal $2,000,000 during any given month,
no Contingency Reserve will be required; and

b) should Excess Availability be less than $2,000,000 during any given month,
then the Contingency Reserve shall be determined as follows:

[Rental & third party + vessel rental + surveying] x ACCTS. PAYABLE TURNOVER
DAYS

                                       30

TERM LOAN EXPOSURE - There exists the risk of potential priming liens on the
Collateral as the result of the Jones Act. As of the Closing Date, no additional
reserves are considered necessary. For so long as Excess Availability exceeds
$2,000,000, no further reserves in connection with the Jones Act will be
established. If however, Excess Availability drops below $2,000,000, the
Contingency Reserve shall be adjusted in accordance with the following formula:

               a)  =  unpaid offshore salary/wages + vessel crew salary/wages
               b)  =  materials + fuel + diving gases + catering + gear rental
               c)  =  b x ACCTS. PAYABLE TURNOVER DAYS

                                    30

The specific calculation will be as follows:

           In Year one:  a + c + equip. loan - 110% of OLV = incremental reserve
           Thereafter:  a + c + equip. loan - 100% of OLV = incremental reserve

        Borrower has duly complied with, and its Property, business operations
and leaseholds are in compliance in all material respects with, the provisions
of all Environmental Laws applicable to Borrower, its Properties or the conduct
of its business, except for the following:

CAL DIVE INTERNATIONAL, INC.

Since August, 1993, Cal Dive has been required pursuant to Section 8.1(U) to
ensure that all Real Property remains in compliance with all Environmental Laws
and to promptly notify Lender upon the receipt of any written notice with regard
to any Hazardous Discharge or violation of Environmental Laws. Reference is made
to the monthly Compliance Certificate for the reporting of any such violations,
all of which have been satisfactorily resolved as of April 30, 1995.

ENERGY RESOURCE TECHNOLOGY

Since commencing offshore operations there have been minor oil spills (less than
10 gallons) required to be reported to either the MMS and/or EPA (see enclosed).
Both of these matters have been satisfactorily resolved as of April 30, 1995.

OPA 90

Borrower is not in compliance with the financial responsibility requirement of
the Offshore Pollution Act of 1990 ("OPA") and the interim regulations currently
in effect related thereto, which requires Borrower to establish and maintain
evidence of financial responsibility of $150,000,000 to meet the amount of
liability to which Borrower could be subjected under Section 2704(a) of OPA
because insurance for such amount is not available at a reasonable cost. Since
the situation affects a substantial majority of offshore operators and property
owners, the MMS has conducted public hearings to consider how this Section of
the law should be implemented. It is our understanding that a bill before the
U.S. House of Representatives would return the financial responsibility
threshold to a $35,000,000 requirement which existed prior to the enactment of
OPA.. Borrower agrees to use its best efforts to inform Lender of any changes to
the financial responsibility reqirement of OPA and its compliance therewith.

      C. Borrowers have requested that Lender consent to, and waive any Default
(as defined in the Loan Agreement) or Event of Default (as defined in the Loan
Agreement) which may occur as a result of, the following transactions:

            (i) The sale by Cal Dive, First Reserve (as defined in the Loan

to existing negative pledge agreements, subject to, among other things, the
condition that upon the occurrence of a Default or Event of Default under the
Loan Agreement and the request of Lender, ERT shall promptly execute new
negative pledge agreements.

      NOW, THEREFORE, in consideration of the premises herein contained and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties, intending to be legally bound, agree as

            Further, for the purpose of computing interest, all items of payment
            received by Lender shall be applied by Lender (subject to final
            payment of all drafts and other items received in form other than
            immediately available funds) against the Obligations on the day of
            receipt. The determination of when a payment is received by Lender

            necessary and desirable action to cause the aggregate number of
            Directors of the Company under paragraph (a) of this Section 2.1 to
            decrease by such number of CSO Directors as then resign or (iii) if
            the CSO Shareholders cease to own at least 5% of the outstanding
            capital stock of the Company, all the CSO Directors shall
            immediately resign and the Board shall

            thereafter take all necessary and desirable action to cause the

            of Executive Directors as then resign or (iii) if the CDI
            Shareholders cease to own at least 5% of the outstanding capital
            stock of the Company, all the Executive Directors shall immediately
            resign and the Board shall immediately thereafter take all necessary

           PROVIDED, FURTHER, that in the event the Company issues or sells any
           shares of its capital stock or any securities that, directly or
           indirectly, are exercisable, convertible or exchangeable into or for
           shares of its capital stock in a Public Offering, the percentage
           ownership threshold amounts of outstanding capital stock of the
           Company contained in the provisos set forth above in this paragraph
           (b) shall, to the extent each Shareholder group continues to own at
           least 5% of the issued and outstanding capital stock of the Company
           immediately prior to such Public Offering, be proportionately
           decreased by multiplying each such percentage ownership threshold
           amount by a fraction the numerator of which shall be the total number
           of shares of capital stock of the Company outstanding immediately
           prior to such Public Offering and the denominator of which shall be
           the total number of shares of capital stock of the Company
           outstanding immediately after the completion of such Public Offering
           (including any over-allotment option relating thereto);

            (c) the removal from the Board or a Subsidiary Board, subject to
            applicable law, of (i) any Director designated hereunder at the

            above or (ii) any Director for Cause at the written request of the
            Board, following a Supermajority Vote of the Board, but only upon
            such written request and under no other circumstances; PROVIDED
            that, notwithstanding clause 2.1(b)(iii) above, if any Executive
            Director elected pursuant to clause 2.1(b)(iii) above ceases to be
            an employee of the Company or any of its Subsidiaries or a
            shareholder of at least 5% of the issued and outstanding Shares,

                                    - 8 -

            such Director shall be removed as a Director promptly upon the later
            of the termination of his employment or cessation of ownership of at
            least 5% of the issued and outstanding Shares;

            (d) in the event that any Director designated hereunder for any
            reason ceases to serve as a member of the Board or a Subsidiary
            Board during his term of office, the Person or Persons who
            previously designated such Director pursuant to paragraph 2.1(b)
            above shall be entitled to designate a successor Director to fill
            the vacancy created thereby on the terms and subject to the
            conditions of this Section 2.1.

            (e) so long as the CSO Shareholders or the Fund Shareholders or the
            CDI Shareholders have the right to designate more than one (1)
            Director pursuant to paragraph 2.1(b) above, the Company shall cause
            the Directors designated by such Shareholder group then serving on
            the Board to be apportioned among the various classes of Directors
            in order to ensure that their respective terms expire in consecutive
            years.

           2.2 COMMITTEES OF THE BOARD. The Board shall in accordance with the

            2.4 COMPETITORS AS DIRECTORS. Notwithstanding anything to the
contrary contained in this Article 2, no Shareholder shall vote or be required
to vote to elect any officer, director, employee, consultant, advisor, Affiliate
or partner of a Competitor (or Affiliate thereof), to the Board or any
Subsidiary Board; PROVIDED that the Person who designated such proposed Director
pursuant to paragraph 2.1 (b) hereof shall be entitled to designate a

           2.5 COMPANY INFORMATION. The Company shall deliver to the Directors
any and all financial and other information relating to the Company and its

                                  ARTICLE 3.
                               IRREVOCABLE PROXY

           In order to effectuate the provisions of Section 2.1(a), (b), (c),
(d) and (e), the CDI Shareholders, the Fund Shareholders and the CSO
Shareholders each hereby appoint the appropriate Proxy as his or its true and
lawful proxy and attorney-in fact, with full power of substitution, to vote at
any annual or special meeting of shareholders of the Company, or, if permitted
by law and the Company's Articles of Incorporation or By-Laws, to take action by
written consent in lieu of such meeting with respect to, or to otherwise take
action in respect of, all of the Shares owned or held of record by them in

                                  ARTICLE 4.
                      RESTRICTIONS ON TRANSFER OF SHARES

           4.1 LIMITATIONS ON TRANSFER OF SHARES. (a) Except as provided in this
Agreement and except for transfers contemplated or permitted by the Purchase
Agreement, each Shareholder hereby agrees that such Shareholder will not,
directly or indirectly, Transfer any Shares or Voting Trust Certificates (or any
interest therein).

           (b) Each Shareholder hereby agrees that: (i) any Transfer in
violation of this Agreement shall not be recognized on the books of the Company
and shall be void and (ii) no Transfer shall occur unless the transferee shall
agree pursuant to Article 7 to become a party to and be bound by the terms of
this Agreement, and, with respect to Employee Shareholders, the Voting Trust
Agreement and an Employee Stock Agreement.

           4.2 RIGHTS OF FIRST REFUSAL. (a) Subject to the provisions of this
Article 4 and Section 2 of the Employee Stock Agreement, at least 60 days prior
to making any Transfer of any interest in any Shares or Voting Trust
Certificates (other than pursuant to Rule 144 promulgated under the Securities
Act ("Rule 144") or an underwritten Public Offering or as provided in the
proviso in paragraph 4.2 (c) below), the transferring Shareholder (the
"Transferring Shareholder") shall deliver a written notice (the "Offer Notice")
to the Company and the other Shareholders. The Offer Notice shall set forth in
reasonable detail the name of the Transferring Shareholder, the number of Shares
or Voting Trust Certificates proposed to be so Transferred (the "Offered
Securities"), the name and address of the proposed transferee (in the case of a
Transfer other than pursuant to a Public Offering which is not underwritten),
the proposed amount of consideration (which shall be payable solely in cash and
which, in the case of a Transfer pursuant to a Public Offering which is not
underwritten, shall be based on the average daily trading price of the Common
Stock over the 30-day period ending on the business day immediately preceding
the date of the Offer Notice) and the other terms and conditions of payment
offered by the proposed transferee.

           (b) If the Transferring Shareholders (in whole or in part) consist of
any Executive Shareholder, Ahalt or any Other Company Shareholder (the "Employee
Group"), the non-selling members of the Employee Group may elect to purchase all
(but not less than all) of their Pro Rata Share (as defined below) of the
Offered Securities being sold by members of the Employee Group at the price and
on the other terms specified in the Offer Notice by delivering written notice of
such election to the Transferring Shareholder and the other members of the
Employee Group (or the Company's Secretary) as soon as practicable but in no
event later than 10 days after the delivery of the Offer Notice. If any members
of the Employee Group did not elect to purchase their Pro Rata Share of the
Offered Securities within such 10-day period, each of the other members of the
Employee Group who has so elected may elect to purchase all or part of the
remaining Offered Securities at the price and on the other terms specified in
the Offer Notice by delivering written notice of such election to the
transferring Shareholder and the other members of the Employee Group (or the
Company's secretary) as soon as practicable but in no event later than 20 days

                                    - 11 -
<PAGE>
after initial delivery of the Offer Notice; PROVIDED, that, in case there are
more elections than there are Offered Securities, such additional Shares shall
be allocated to such members of the Employee Group in accordance with their Pro
Rata Share; it being the intention of the parties that the Offered Securities
that are proposed to be Transferred by the members of the Employee Group be
offered first to non-selling members of the Employee Group.

           (c) If the Transferring Shareholders consist of one or more of the
Fund Shareholders (the "Fund Group") and the proposed transferee is not another
Fund Shareholder, or an Affiliate of any of the Fund Shareholders, such Transfer
is subject to this Article 4; PROVIDED, HOWEVER, that the rights of first
refusal provided in this Section 4.2 shall not apply to a Transfer by any member
of the Fund Group or any Permitted Transferee thereof (as defined in Section
4.6) to a financial or other similar institutional investor or investment fund
which is not a Competitor and which, in connection with such Transfer, is
expressly not assigned, and is expressly prohibited from succeeding to, any of
the rights of the Fund Shareholders or their Permitted Transferees to designate
Directors under Article 2.

           (d) If the Transferring Shareholders consist of CSO or a CSO
Affiliate (the "CSO Group") and the proposed transferee is not another CSO
Affiliate, such transfer is subject to this Article 4.

           (e) If the Employee Group as a whole, in the case of paragraph 4.2
(b), has not elected to purchase all of the Offered Securities within the
first-offer periods specified therein, or if the Fund Group or CSO Group
proposes a Transfer that is subject to this Article 4, any Offered Securities
shall be offered during the following 10-day period to the Company. If the
Company does not elect to purchase all of the Offered Securities within such
10-day period pursuant to a Supermajority Vote of the Board in accordance with
Article 8, any remaining Offered Securities shall then be offered during the
following 10-day period to all other Shareholders in accordance with their Pro
Rata Share. If any such other Shareholders do not elect to purchase all of their
respective Pro Rata Share of such Offered Securities within such 10-day period,
any remaining Offered Securities shall then be offered to all those Shareholders
electing to purchase Offered Securities during the next succeeding 10-day
period, in accordance with their respective Pro Rata Share or as the
Shareholders electing to purchase at that time may otherwise agree. The offering
periods referred to in this Section 4.2 are collectively referred to as the
"Election Period". Each Shareholder agrees not to consummate any Transfer until
expiration of the Election Period unless the parties to the Transfer have been
finally determined pursuant to this Section at any time prior to the expiration
of such Election Period.

           (f) If, but only if, the other Shareholders and/or the Company, as
the case may be, have elected to purchase all of the Offered Securities from the
Transferring Shareholder, the Transfer of such Offered Securities shall be
consummated as soon as practicable after the delivery of the election notices,
but in no event later than 30 days after the expiration of the Election Period.

           (g) If the other Shareholders and/or the Company, as the case may be,
have not elected to purchase all of the Offered Securities, the Transferring
Shareholder may, within 90 days after the 

                                    - 12 -
<PAGE>
expiration of the Election Period and subject to the provisions of Section 4.3,
Transfer such Offered Securities to the Person(s) named in the Offer Notice at a
price not less than the price per Share specified in the Offer Notice and on
other terms no more favorable to the transferee than offered to the Company and
the other Shareholders in the Offer Notice. If such Transfer does not occur
within such 90-day period, this Section 4.2 shall be applicable with respect to
all future Transfers of such Offered Securities.

           (h) The purchase price specified in any Offer Notice shall be payable
solely in cash at the closing of the transaction; PROVIDED, that, with respect
solely to Transfers among Shareholders of the Company pursuant to the provisions
of this Section 4.2, other bona fide arrangements and terms which are acceptable
to the Transferring Shareholder can be considered. For purposes hereof, each
Shareholder's "Pro Rata Share" shall be based upon such Shareholder's percentage
ownership of Shares on a fully-diluted basis relative to other Shareholders to
whom an offer has been made pursuant to this Section 4.2.

            4.3 TAG-ALONG RIGHTS. (a) Subject to the provisions of Article 5 and
limitations in Section 4.1 and the procedures of Section 4.2, at least 10 days
prior to a Transfer by a Shareholder that is subject to this Article 4 (other
than pursuant to a Public Offering or Rule 144), the Shareholder desiring to
make such Transfer shall deliver a written notice (the "Sale Notice") to the
Company and the other Shareholders, setting forth the name of the Transferring
Shareholder, the number of Shares proposed to be so Transferred, the name and
address of the proposed transferee, the proposed amount and form of
consideration and other terms and conditions of payment offered by the proposed
transferee, and a representation that the proposed transferee has been informed
of the tag-along rights provided for in this Section 4.3 and has agreed to
purchase Shares in accordance with the terms hereof.

           (b) The other Shareholders may elect to participate in the
contemplated Transfer by delivering written notice indicating their desire to
exercise their rights pursuant to this Section to the Transferring Shareholder
at any time within 10 days after delivery of the Sale Notice. If any other
Shareholder has elected to participate in such Transfer (a "Tagging
Shareholder"), the Transferring Shareholders and the Tagging Shareholders shall
be entitled to sell in the contemplated Transfer, at the same price and on the
same terms, a number which is the product of (i) the quotient determined by
dividing the percentage of Shares beneficially owned on a fully diluted basis by
such Person by the aggregate percentage of Shares owned by the Transferring
Shareholders and the Tagging Shareholders participating in such Transfer and
(ii) the number of shares to be sold in the contemplated Transfer.

            FOR EXAMPLE, if the Sale Notice contemplated a sale of 10,000 Shares
            by the Transferring Shareholder, and if the Transferring Shareholder
            at such time beneficially owns 20% of all Shares and if one other
            Shareholder elects to participate and beneficially owns 5% of all
            Shares, the Transferring Shareholder would be entitled to sell 8,000
            shares (20% divided by 25% x 10,000 shares) and the Tagging
            Shareholder would be entitled to sell 2,000 shares (5% divided by
            25% x 10,000 shares).

                                    - 13 -
<PAGE>
           (c) In order to be entitled to exercise its right to sell Shares to
the proposed transferee pursuant to Section 4.3(b), a Tagging Shareholder must
agree to make to the transferee substantially the same representations,
warranties, covenants, indemnities and agreements as the Transferring
Shareholder agrees to make in connection with the proposed Transfer (except that
in the case of representations and warranties pertaining specifically to the
Transferring Shareholder, a Tagging Shareholder shall make the comparable
representations and warranties pertaining specifically to itself); PROVIDED that
all representations and warranties shall be made by Tagging Shareholders
severally and not jointly and that the liability of the Transferring
Shareholders and the Tagging Shareholders (whether pursuant to a representation,
warranty, covenant, indemnification provision or agreement) for liabilities in
respect of the Company shall be evidenced in writings executed by them and the
transferee and shall be borne by each of them on a pro rata basis.

           (d) If the proposed transferee fails to purchase Shares from any
Tagging Shareholder that has properly exercised its tag-along rights pursuant to
this Section 4.3, then the Transferring Shareholder shall not be permitted to
make the proposed Transfer, and any such attempted Transfer shall be void and of
no effect, as provided in Article 7.

           (e) Each Transferring Shareholder agrees not to consummate any such
Transfer until 10 days after delivery to the other Shareholders of the Sale
Notice, unless the parties to the Transfer have been finally determined pursuant
to this Agreement prior to the expiration of such period. If any of the Tagging
Shareholders exercise their rights under this Section 4.3, the closing of the
sale of the Shares or Voting Certificates, as the case may be, by such Tagging
Shareholder with respect to which such rights have been exercised shall take
place concurrently with the closing of the sale of the Shares or Voting Trust
Certificates, as the case may be, by the Transferring Shareholder with respect
to which the Sale Notice was given. No Transfer shall occur pursuant to this
Section 4.3 unless the transferee shall agree to become a party to, and be bound
to the same extent as its transferor by the terms of, this Agreement pursuant to
the provisions of Article 7.

           4.4 DRAG-ALONG RIGHTS. Subject to the provisions of Section 5.3 and
notwithstanding, in the case of the CSO Shareholders, the provisions of Section
10.2, each Shareholder hereby agrees that, in connection with any Sale of the
Company in accordance with Article 5 or, in the case of all Shareholders other
than the CSO Shareholders, in accordance with, Section 10.1 it will Transfer all
of its Shares to such Third Party Purchaser or to CSO and/or its Affiliate(s),
as applicable, in any such transaction; PROVIDED that the terms of such offer
applicable to any Shares owned by the Transferring Shareholder or CSO
Shareholders, as applicable, and its Permitted Transferees are not more
favorable than the terms of such offer applicable to the Shares owned by the
other Shareholders (including, without limitation, with respect to the amount
and nature of consideration and the time of receipt thereof).

           4.5 TRANSFER TO COMPETITORS. No Shareholder shall, directly or
indirectly, Transfer in any transaction or series of transactions (related or
not) any Shares or Voting Trust Certificates to any Competitor other than
pursuant to a Sale of the Company or a Public Offering.

           4.6 PERMITTED TRANSFERS. The restrictions and procedures contained in
this Article 4 shall not apply with respect to any Transfer of Shares or Voting
Trust Certificates by any Shareholder (i) in the case of the Executives, Ahalt
and the Other Company Shareholders, pursuant to applicable laws of descent and
distribution or to an Immediate Family Member or to the Company pursuant to the
Employee Stock Agreement or to any Other Company Shareholder or Executive
Shareholder, (ii) in the case of the Fund Shareholders, to any other Fund
Shareholder or to any Affiliate thereof, or (iii) in the case of any CSO
Shareholder, to any Affiliate of CSO; provided that the restrictions contained
in this Article 4 shall continue to be applicable to the Shares after any such
Transfer; and PROVIDED, FURTHER that the transferees of such Shares (each such
permitted transferee in accordance with this Section 4.6 being referred to as a
"Permitted Transferee"), shall, prior to any such Transfer, agree to become a
party to, and be bound to the same extent as its transferor by the terms of,
this Agreement pursuant to the provisions of Article 7.

                                  ARTICLE 5.
                     RIGHTS TO CAUSE A SALE OF THE COMPANY

           5.1 RIGHTS OF THE CSO OR FUND SHAREHOLDERS. In the event that no Sale
of the Company or Public Offering has occurred prior to December 31, 1999,
either the Fund Shareholders holding a majority of the Fund Shares or the
holders of a majority of the CSO Shares shall have the right to cause a Sale of
the Company pursuant to the provisions of Section 5.3.

           5.2 RIGHTS OF THE EXECUTIVE SHAREHOLDERS. If no Sale of the Company
or Public Offering has occurred prior to December 31, 1999, the holders of

Sale of the Company pursuant to the provisions of Section 5.3; PROVIDED, at such
time, all holders of Executive Shares own at least 10% of the total outstanding
shares of Common Stock of the Company; and, PROVIDED, FURTHER, that such Third
Party Transaction (as defined below) does not provide for or contemplate, and
does not result in, any Executive Shareholder receiving compensation or other
consideration at any time within two years thereafter, whether as an employee,
director, consultant or agent or in any other capacity other than as a
shareholder, materially in excess of such Executive's then current per annum
compensation from the Company.

           5.3 PROCEDURES FOR SALE OF THE COMPANY. (a) Notwithstanding anything
to the contrary contained in any Employee Stock Agreement, if the Fund
Shareholders, the CSO Shareholders or the Executive Shareholders shall have the
right to cause a Sale of the Company pursuant to Section 5.1 or 5.2, such
Shareholder group (collectively, the "Proposing Shareholder") shall request the
Company to take all steps necessary or desirable to consummate a Sale of the
Company within 180 days following the date 

                                    - 15 -
<PAGE>
such request was delivered by the Proposing Shareholder to the Company. Promptly
after receipt of such request, the Company will give written notice of such
requested Sale to all other Shareholders and will, as expeditiously as possible,
use its best efforts to (i) retain a nationally recognized investment banking
firm to assist in such Sale of the Company and to render an opinion as to the
fairness, from a financial point of view, of the consideration to be received by
the Shareholders in any Sale of the Company (a "Fairness Opinion"); (ii) seek
and produce a Third Party (a "Third Party Purchaser") to acquire (x) all of the
issued and outstanding capital stock of the Company (whether by merger,
consolidation or sale or transfer of the Company's capital stock) or (y) all or
substantially all of the Company's assets on a consolidated basis (a transaction
of the type referred to in clause (x) or (y) above shall be referred to herein
as a "Third Party Transaction"); and (iii) negotiate the terms of such Third
Party Transaction with a view to reaching an agreement in principle documented
in a writing between such parties as soon as practicable. Except as required by
law, the Company shall not be obligated to seek the consent of the Shareholders
prior to commencing any of the foregoing actions in connection with a Sale of
the Company.

            (b) If the Company identifies and reaches an agreement in principle
with a potential Third Party Purchaser, then the Company shall deliver written
notice to the Shareholders setting forth in reasonable detail the terms of the
proposed Third Party Transaction (the "Company Sale Notice"), together with the
Fairness Opinion. Within 30 days following receipt of the Company Sale Notice
(the "Sale Election Period"), any of the Shareholders shall deliver to the
Company and the other Shareholders written notice setting forth such holders'
election, if any, to deliver a written offer (a "Shareholder Offer"), upon
substantially the same terms as described in the Company Sale Notice, to acquire
the Company (a "Shareholder Transaction"). In addition, upon receipt of the
Company Sale Notice, the CSO Shareholders shall have the rights provided in
Section 10.2.

           (c) If the Fund Shareholders, the CSO Shareholders or and the
Executive Shareholders have not delivered a Shareholder Offer within the Sale
Election Period, the Company shall consummate the Third Party Transaction on the
terms specified in the Company Sale Notice as soon as practicable following such
Sale Election Period and in any event within 45 days thereafter. If for any
reason the Third Party Transaction is not consummated within such 45 day period,
or the Company does not take steps to or is otherwise unable to effect a Sale of
the Company in accordance with Section 5.3, the Proposing Shareholders shall
have the right to take all steps which the Company was required to take to
effect a Sale of the Company in accordance with the provisions of this Section
5.3 (including the requirement to obtain a Fairness Opinion). If any of the
Shareholders has delivered a Shareholder Offer within the Sale Election Period,
the Company and the other Shareholders shall consummate the Shareholder
Transaction within 90 days of receipt by the Proposing Shareholder of the
Shareholder Offer. If the Shareholder Transaction is not consummated within such
90 day period, the other Shareholders must again comply with the provisions of
this Section 5.3. Subject to the provisions of Sections 4.4 and 5.3(d) and, in
the case of the CSO Shareholders, the provisions of Section 10.2, (i) in the
case of a Third Party Transaction, the Proposing Shareholders and all other
Shareholders shall be required to sell all of their Shares in such transaction
and (ii) in the case of a Shareholder Transaction, the Proposing Shareholder
shall and all other Shareholders 

                                    - 16 -
<PAGE>
other than the Shareholder that made the Shareholder Offer shall be required to
sell all of their Shares in such transaction.

           (d) The other Shareholders or the Proposing Shareholder, as the case
may be, shall not be obligated to participate in a Third Party Transaction or a
Shareholder Transaction, respectively, if upon consummation of the Third Party
Transaction, all holders of Common Stock do not receive the same form and amount
of consideration per share of Common Stock (including for this purpose amounts
allocated to noncompetition, consulting and other arrangements), or if certain
holders of Common Stock are given an option as to the form and consideration to
be received, and the other holders of Common Stock have not been given the same
option.

                                   TRANSFERS

           In the event of any purported Transfer of any Shares in violation of

                                  ARTICLE 9.

            9.1 LIMITED PREEMPTIVE RIGHTS. (a) Except for issuances of capital
stock of the Company (i) in accordance with any Stock Option Plan, (ii) solely
to the extent provided in to the last sentence of this 

                                    - 19 -

Section 9.1(a), pursuant to a Public Offering, or (iii) in connection with an
acquisition of another Person (subject to the provisions of Section 10.1) by the
Company or any of its Subsidiaries, or in settlement of indebtedness of the
Company or any of its Subsidiaries or in settlement of a lawsuit or other claim
involving the Company or any of its Subsidiaries, if at any time the Company
authorizes the issuance or sale of any shares of capital stock of the Company or
any securities that, directly or indirectly, are convertible into or
exchangeable for capital stock of the Company or any securities containing
options, rights or warrants to acquire any shares of capital stock of the
Company or any securities that, directly or indirectly, are convertible into or
exchangeable for capital stock of the Company (other than as a dividend on the
outstanding Common Stock) the Company shall first offer to sell, on a pro rata
basis, to the Fund Shareholders and the CSO Shareholders (collectively, the
"Purchaser Parties") and the Executive Shareholders a portion of such stock or
securities equal to the quotient determined by dividing (1) in the case of the
Fund Shareholders or the CSO Shareholders, the number of shares of Common Stock
Beneficially Owned by the Fund Shareholders or the CSO Shareholders, as
applicable (collectively the "Purchaser Common Stock") and (2) in the case of
Executive Shareholders, the number of shares of Common Stock held by the
Executive Shareholders ("Employee Stock") divided by the total number of shares
of Common Stock outstanding. Each holder of Purchaser Common Stock and Employee
Stock shall be entitled to purchase such stock or securities at the most
favorable price and on the most favorable terms as such stock or securities are
to be offered to any other Person. The purchase price for all stock and
securities offered to the holders of the Purchaser Common Stock or Employee
Stock shall be payable in cash unless other suitable terms are offered to such
Shareholders. In addition to the foregoing, the Company shall afford the
Purchaser Parties the opportunity to purchase their pro rata portion of any
stock or securities (as determined above) to be offered by the Company pursuant
to a Public Offering (other than the initial Public Offering of the Company),
unless the managing underwriter(s) for such offering state in writing that, in
their opinion, such set-aside would materially adversely affect the
marketability of such offering.

      (b) In order to exercise its purchase rights hereunder, a holder of
Purchaser Common Stock or Employee Stock must within 15 days after receipt of
written notice from the Company describing in reasonable detail the stock or
securities being offered, the purchase price thereof, the payment terms and such
holder's percentage allotment, deliver a written notice to the Company
describing its election hereunder. If all of the stock and securities offered to
the holders of Purchaser Common Stock or Employee Stock is not fully subscribed
by such holders, the remaining stock and securities shall be reoffered by the
Company to the holders purchasing their full allotment upon the terms set forth
in this paragraph, except that such holders must exercise their purchase rights
within five days after receipt of such re-offer. This Section 9.1 shall not be
applicable to any transactions to be consummated under any other provision of
this Agreement.

      (c) Upon the expiration of the offering periods described above, the
Company shall be entitled to sell such stock or securities which the holders of
Purchaser Common Stock or Employee Stock have not elected to purchase, during
the 90 days following such expiration on terms and conditions no more 

                                    - 20 -
<PAGE>
favorable to the purchaser thereof than those offered to such holders. Any stock
or securities offered or sold by the Company after such 90-day period must be
re-offered to the holders of Purchaser Common Stock or Employee Stock pursuant
to the terms of this Section 9.1.

days after the date of such Board approval; or (b) (i) the commencement of
efforts to seek or solicit in any manner a Sale of the Company with or without

other Person or assets or group of assets which at the time of such acquisition

excess of 50% of the market value of the Company (based on the average daily
trading price of the Common Stock over the 30 day period immediately preceding
such transaction, if the initial Public Offering of the Company shall then have
been completed or, if such initial Public Offering shall not have then been
completed, based on the valuation of the Company prepared by an Independent
Appraiser (as defined below)) (a "Significant Acquisition"), the CSO
Shareholders and/or their Affiliates shall have the right to acquire the Company
subject to applicable law at a purchase price equivalent to the fair market
value thereof based on a valuation of the Company prepared by a nationally

Company) and provide its or their approvals as a shareholder of the Company as
may be required in connection with any acquisition of the Company by the CSO
Shareholders and/or their Affiliates pursuant to this Section 10.1. In the event
the CSO Shareholders and/or their 

                                    - 21 -
<PAGE>
Affiliates shall have notified the Company of its or their election to acquire
the Company pursuant to this Section 10.1, the Company shall not complete or
take any further action with respect to any Agreed Sale of the Company,

valuation prepared by an Independent Appraiser in which the fair market value of
the Joint Venture is defined as the fair market value of the Company (including
the fair market value of the Joint Venture) less the fair market value of the
Company without the fair market value of Joint Venture, by delivering written
notice of such election to the Company within 15 days after the date of such
Board approval or the date of the Company Sale Notice, as applicable, provided
that at such time the CSO Shareholders own in the aggregate at least 5% of the
total outstanding shares of Common Stock of the Company.

      10.3 CSO ANTI-DILUTION PROTECTION. It is currently the Company's
expectation (without any obligation) that it may, subject to and in the
discretion of its Board, undertake to effect an initial Public Offering of its
Common Stock under the Securities Act pursuant to which the Company will raise
capital to be used for future company development. Notwithstanding the
foregoing, in the event of any such initial Public Offering, the CSO
Shareholders shall not be diluted to less than 24% of the issued and outstanding
Common Stock on a fully diluted basis as a result of such initial Public
Offering (including any over-allotment option relating thereto).

holders of the Fund Shares, CSO Shares and/or Executive Shares, respectively, so
long as each such group of Shareholders continue to own as a group at least 5%
of the outstanding Common Stock (after which this Agreement shall no longer
apply to any such Shareholder group which does not own as a group at least 5% of
the outstanding Common Stock but shall continue to apply to each such other
Shareholder group which does own as a group at least 5% of the outstanding
Common Stock).

           11.2 ADDITIONAL SECURITIES SUBJECT TO AGREEMENT. Each Shareholder
agrees that any other equity securities of the Company which it shall hereafter
acquire by means of a stock split, stock dividend, distribution, purchase,

held on the date hereof.

           11.3 INJUNCTIVE RELIEF. Each Shareholder acknowledges and agrees that

respect to the Shares or any other securities of the Company, unless otherwise
provided for herein or permitted hereby.

           11.5 AMENDMENT AND WAIVER. Except as otherwise provided herein, no

party to enforce any of the provisions of this Agreement shall not affect the
right of such party thereafter to enforce each and every provision of this
Agreement in accordance with its terms.

                          REGISTRATION RIGHTS AGREEMENT

        THIS REGISTRATION RIGHTS AGREEMENT, dated as of January 12, 1995 (this
"Agreement"), among Cal Dive International, Inc., a Minnesota corporation (the
"Company"), First Reserve Secured Energy Assets Fund, Limited Partnership, a
Delaware limited partnership ("SEA"), First Reserve Fund V, Limited Partnership,
Delaware limited partnership ("Fund V"), First Reserve Fund V-2, Limited
Partnership, a Delaware limited partnership ("Fund V-2"). First Reserve Fund VI,

SEA, Fund V and Fund V-2, the "Funds"), Gerald G. Reuhl, Owen Kratz and S. James

Dive International, Inc. Voting Trust (the "Trust").

                                    RECITALS

        The Funds, the Executives and the Company are parties to a Purchase
Agreement, dated as of the date hereof (the "Purchase Agreement"), pursuant to
which the Funds are purchasing 221,985 shares of the common stock of the Company
without par value ("Common Stock") from the Company's treasury and an aggregate
of 332,978 shares of Common Stock from the CDI Shareholders (as defined in the
Shareholders Agreement (as defined below)). In order to induce the Funds and the
Executives to enter into the Purchase Agreement, the Company has agreed to
provide the registration rights set forth in this Agreement.

        The Funds, the CDI Shareholders and the Company are parties to an
Amended and Restated Shareholders Agreement, dated as of the date hereof (the
"Shareholders Agreement").

        The execution and delivery of this Agreement is a condition precedent to
the obligation of the Funds to purchase Common Stock from the Company and the
CDI Shareholders pursuant to the Purchase Agreement and to enter into the
Shareholders Agreement.

                                    AGREEMENT

        NOW THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, receipt of which is
hereby acknowledged, the parties hereto agree as follows:

        1.     DEFINITIONS.  (a)  Unless otherwise defined herein, terms
defined in the Shareholders Agreement are used herein as defined therein.
For purposes of this Agreement, the following terms have the meanings set
forth below:

                                        1

        "Executive Registrable Securities" means (i) any Common Stock issued to
the Executives (or their Permitted Transferees (as defined in the Shareholders
Agreement)) and/or issued in the future to other employee shareholders of the
Company and held by the Trust, (ii) any common Stock issued or issuable with
respect to the Common Stock referred to in clause (i) above by way of stock
dividend or stock split, or in connection with a combination of shares,
recapitalization, merger, consolidation, or other reorganization. and (iii) any
other shares of Common Stock held by the Executives (or their Permitted
Transferees) or by the Trust.

        "Funds' Registrable Securities" means (i) any Common Stock purchased by
the Funds pursuant to the Purchase Agreement, (ii) any Common Stock issued or
issuable with respect to the Common Stock referred to in clause (i) above by way
of stock dividend or stock split or in connection with a combination of shares,
recapitalization, merger, consolidation, or other reorganization, and (iii) any
other shares of Common Stock held by the Funds.

        "Registrable Securities" means the Executive Registrable Securities and
the Funds' Registrable Securities. As to any particular Registrable Securities,
such securities shall cease to be Executive Registrable Securities or Funds'
Registrable Securities, as the case may be, when they have been distributed to
the public pursuant to an offering registered under the Securities Act or sold
to the public through a broker, dealer or market maker in compliance with Rule
144 under the Securities Act (or any similar rule then in force). For purposes
of this Agreement, a holder shall be deemed to be a holder of Registrable
Securities whenever such Person has the right to acquire directly or indirectly
such Registrable Securities (upon conversion or exercise in connection with a
transfer of securities or otherwise, but disregarding any restrictions or
limitations upon the exercise of such right), whether or not such acquisition
has actually been effected.

        2.     DEMAND REGISTRATIONS.

        (a) REQUEST FOR REGISTRATION. At any time after the earlier of (i) the
fifth anniversary of the date hereof or (ii) a Public Offering, the holders of
(x) the Funds' Registrable Securities or (y) the holders of Executive
Registrable Securities, in each case who own, in the aggregate, not less than
10% of the total outstanding shares of Common Stock, as the case may be, may
request registration under the Securities Act of all or part of their Funds'
Registrable Securities or Executive Registrable Securities, respectively. Within
ten days after receipt of any such request (which shall specify the amount of
Registrable Securities to be registered), the Company shall give written notice
of such requested registration to all other holders of Registrable Securities
and shall include in such registration all Registrable Securities with respect
to which the Company has received written requests for inclusion therein

                                        2

within 15 days after the receipt of the Company's notice. All registrations
requested pursuant to this Section 2(a) are referred to herein as -Demand
Registrations."

        (b) DEMAND REGISTRATIONS. The holders of Funds' Registrable Securities
and Executive Registrable Securities will each be entitled to request two Demand
Registrations; PROVIDED, that, at the time of such request, the holders making
such request own, in the aggregate, not less than 10% of the total outstanding
shares of Common Stock. A registration will not count as one of the permitted
Demand Registrations until it has become effective, and a registration initiated
as a Demand Registration will not count as one of the permitted Demand
Registrations unless the holders of the Funds' Registrable Securities or the
Executive Registrable Securities, as the case may be, initiating such Demand
Registration are able to register and sell at least 50% of the Registrable
Securities requested by such holder to be included in such registration;
PROVIDED that in any event the Company shall pay all Registration Expenses in
connection with any registration initiated as a Demand Registration. All Demand
Registrations shall be underwritten registrations. The Company and each holder
will pay a pro rata portion of the Registration Expenses in accordance with
Section 6(c).

        (c) PRIORITY ON DEMAND REGISTRATIONS. The Company shall not include in
any Demand Registration any securities which are not Registrable Securities
without the prior written consent of the holders of a majority of the
Registrable Securities initially requesting such registration. If in connection
with a Demand Registration the managing underwriters advise the Company in
writing that in their opinion the number of Registrable Securities and, if
permitted hereunder, other securities requested to be included in such offering,
exceeds the number of Registrable Securities and other securities, if any, which
can be sold in an orderly manner in such offering within a price range
acceptable to the holders of a majority of the Registrable Securities initially
requesting registration, the Company shall include in such registration (i)
first, up to 50% of the Registrable Securities requested to be included in such
registration, pro rata among the holders of such securities on the basis of the
number of Shares owned by the Funds (with respect to those Registrable
Securities requested to be included which are held by the Funds), on the one
hand, and the Executives (with respect to those Registrable Securities requested
to be included which are held by the Executives), on the other, (ii) second, all
remaining Fund Registrable Securities and any Executive Registrable Securities
requested to be included in such registration, pro rata among the holder of such
securities on the basis of the number of Shares owned by the Funds, on the one
hand, and the Executives, on the other (excluding the Funds' Registrable
Securities and the Executive Registrable Securities included pursuant to (i)
above) and (iii) third, other securities requested to be included in such
registration.

                                        3

        (d) RESTRICTIONS ON DEMAND REGISTRATION. The Company shall not be
obligated to effect any Demand Registration within six months after the
effective date of a previous Demand Registration or a registration in which the
holders of Registrable Securities were given piggyback rights pursuant to
Section 3 and in which there was no reduction in the number of Registrable
Securities requested to be included. The Company may postpone for up to six
months the filing or the effectiveness of a registration statement for a Demand
Registration if the Company and the holders of a majority of each of the Funds'
Registrable Securities and the Executive Registrable Securities agree that such
Demand Registration would reasonably be expected to have an adverse effect on
any proposal or plan by the Company or any of its Subsidiaries to engage in any
acquisition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or similar transaction; PROVIDED that in
such event, the holders of the Funds' Registrable Securities or the Executive
Registrable Securities requesting such Demand Registration shall be entitled to
withdraw such request and, if such request is withdrawn, such Demand
Registration shall not count as a Demand Registration.

        (e) SELECTION OF UNDERWRITERS. The holders of a majority of the
Registrable Securities included in any Demand Registration shall have the right
to recommend the investment banker(s) and manager(s) to administer the offering,
subject to the approval of a majority of the Board which shall not be
unreasonably withheld; PROVIDED, that if any of the Funds' Registrable
Securities are to be included in such Demand Registration, such underwriter
shall be acceptable to the Funds.

        (f) OTHER REGISTRATION RIGHTS. Except as provided in this Agreement, the
Company shall not grant to any Person the right to request the Company to
register any equity securities of the Company, or any securities convertible or
exchangeable into or exercisable for such securities, without the prior written
consent of the holders of a majority of each of the Funds' Registrable
Securities and the Executive Registrable Securities; PROVIDED that the Company
may grant rights to other Persons to (i) participate in Piggyback Registrations
so long as such rights are subordinate to the rights of the holders of
Registrable Securities with respect to such Piggyback Registrations and (ii)
request registrations so long as the holders of Registrable Securities are
entitled to participate in any such registrations with such Persons pro rata on
the basis of the number of Shares owned by such Persons and such participating
holders of Registrable Securities (assuming for this purpose that all Shares
owned by all Funds are aggregated, on the one hand, and all Shares owned by all
Executives are aggregated, on the other hand).

        (g)    REGISTRATION STATEMENT FORM.  If any registration requested
pursuant to this Section 2 which is proposed by the Company to be effected
by the filing of a registration statement on Form S-3 (or any successor or
similar short-form registration statement) shall be in connection with an

                                        4

underwritten public offering, and if the managing underwriter shall advise the
Company in writing that, in its opinion, the use of another form of registration
statement is of material importance to the success of such proposed offering,
then such registration shall be effected on such other form.

        (h) EFFECTIVE REGISTRATION STATEMENT. A registration requested pursuant
to this Section 2 will not be deemed to have been effected unless it has become
effective; PROVIDED that if within 180 days after it has become effective, the
offering of Registrable Securities pursuant to such registration is interfered
with by any stop order, injunction or other order or requirement of the
Securities and Exchange Commission or other governmental agency or court, such
registration will be deemed not to have been effected.

        3.     PIGGYBACK REGISTRATIONS.

        (a) RIGHT TO PIGGYBACK. Whenever the Company proposes to register any of
its securities under the Securities Act (other than pursuant to a Demand
Registration) and the registration form to be used may be used for the
registration of Registrable Securities (a "Piggyback Registration"}, the Company
shall give prompt written notice (in any event within three business days after
its receipt of notice of any exercise of demand registration rights other than
under this Agreement) to all holders of Registrable Securities (and to other
holders of such securities) of its intention to effect such a registration and
shall include in such registration all Registrable Securities with respect to
which the Company has received written requests for inclusion therein within 15
days after such holder's receipt of the Company's notice.

        (b)    PIGGYBACK EXPENSES.  The Registration Expenses of the holders
of Registrable Securities shall be paid by the Company in all Piggyback
Registrations.

        (c) PRIORITY ON PRIMARY REGISTRATIONS. If a Piggyback Registration is an
underwritten primary registration on behalf of the Company, and the managing
underwriters advise the Company in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number
which can be sold in an orderly manner in such offering within a price range
acceptable to the holders of a majority of the Registrable Securities initially
requested to be included in such registration, the Company shall include in such
registration (i) first, the securities the Company proposes to sell, (ii)
second, the Funds' Registrable Securities and the Executive Registrable
Securities requested to be included in such registration, pro rata among the
holders of such securities on the basis of the number of shares owned by each
such holder (assuming for this purpose that all Shares owned by all Funds are
aggregated, on the one hand, and all Shares owned by all Executives are

                                        5

aggregated, on the other hand) and (iii) third, other securities requested to be
included in such registration.

        (d) PRIORITY ON SECONDARY REGISTRATIONS. If a Piggyback Registration is
an underwritten secondary registration on behalf of holders of the Company's
securities, and the managing underwriters advise the Company in writing that in
their opinion the number of securities requested to be included in such
registration exceeds the number which can be sold in an orderly manner in such
offering within a price range acceptable to the holders of a majority of the
securities initially requesting such registration, the Company shall include in
such registration (i) first, the securities requested to be included therein by
the holders requesting such registration and the Funds' Registrable Securities
and the Executive Registrable Securities requested to be included in such
registration, pro rata among the holders of such securities on the basis of the
number of shares owned by each such holder (assuming for this purpose that
securities owned by all Funds, on the one hand, and all Executives, on the other
hand, are aggregated) and (ii) second, other securities requested to be included
in such registration.

        (e) OTHER REGISTRATIONS. If the Company has previously filed a
registration statement with respect to Registrable Securities pursuant to
Section 2 or pursuant to this Section 3, and if such previous registration has
not been withdrawn or abandoned, the Company shall not file or cause to be
effected any other registration of any of its equity securities or securities
convertible or exchangeable into or exercisable for its equity securities under
the Securities Act (except on Form S-8 or any successor form), whether on its
own behalf or at the request of any holder or holders of such securities, until
a period of at least six months has elapsed from the effective date of such
previous registration.

        4.     HOLDBACK AGREEMENTS.

        (a) Each holder of Registrable Securities agrees not to effect any
public sale or distribution (including sales pursuant to Rule 144) of equity
securities of the Company, or any securities convertible into or exchangeable or
exercisable for such securities, during the seven days prior to and the 90-day
period beginning on the effective date of any underwritten Demand Registration
or any underwritten Piggyback Registration in which Registrable Securities are
included (except as part of such underwritten registration), unless the
underwriters managing the registered public offering otherwise agree.

        (b) The Company agrees (i) not to effect any public sale or distribution
of its equity securities, or any securities convertible into or exchangeable or
exercisable for such securities, during the seven days prior to and during the
90-day period beginning on the effective date of any underwritten Demand
Registration or any underwritten Piggyback

                                        6

Registration (except as part of such underwritten registration or pursuant to
registrations on Form S-8 or any successor form), unless the underwriters
managing the registered public offering otherwise agree, and (ii) to cause each
holder of at least 2% (on a fully-diluted basis) of its equity securities, or
any securities convertible into or exchangeable or exercisable for such
securities, purchased from the Company at any time after the date hereof (other
than in a registered public offering) to agree not to effect any public sale or
distribution (including sales pursuant to Rule 144) of any such securities
during such period (except as part of such underwritten registration, if
permitted herein), unless the underwriters managing the registered public
offering otherwise agree.

        5.    REGISTRATION PROCEDURES.

        (a) Whenever the holders of Registrable Securities have requested that
any Registrable Securities be registered pursuant to this Agreement, the Company
shall use its best efforts to effect the registration and the sale of such
Registrable Securities in accordance with the intended method of disposition
thereof, and pursuant thereto the Company shall as expeditiously as possible:

             (i) prepare and file with the Securities and Exchange Commission a
        registration statement with respect to such Registrable Securities and
        use its best efforts to cause such registration statement to become
        effective (provided that before filing a registration statement or
        prospectus or any amendments or supplements thereto, the Company shall
        furnish to the counsel selected by the holders of a majority of the
        Funds' Registrable Securities covered by such registration statement
        copies of all such documents proposed to be filed, which documents shall
        be subject to the review and approval of such counsel);

             (ii) prepare and file with the Securities and Exchange Commission
        such amendments and supplements to such registration statement and the
        prospectus used in connection therewith as may be necessary to keep such
        registration statement effective for a period of not less than six
        months and comply with the provisions of the Securities Act, the
        Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
        the rules and regulations promulgated thereunder with respect to the
        disposition of all securities covered by such registration statement
        during such period in accordance with the intended methods of
        disposition by the sellers thereof set forth in such registration
        statement;

             (iii) furnish to each seller of Registrable Securities such number
        of copies of such registration statement, each amendment and supplement
        thereto (in each case including all exhibits), the

                                        7

        prospectus included in such registration statement (including each
        preliminary prospectus and summary prospectus) in conformity with the
        requirements of the Securities Act, and such other documents as such
        seller may reasonably request in order to facilitate the disposition of
        the Registrable Securities owned by such seller;

             (iv) use its best efforts to register or qualify such Registrable
        Securities under such other securities or blue sky laws of such
        jurisdictions as any seller and the managing underwriter or underwriters
        may reasonably request and do any and all other acts and things which
        may be reasonably necessary or advisable to enable such seller to
        consummate the disposition in such jurisdictions of the Registrable
        Securities owned by such seller; PROVIDED that the Company shall not be
        required to (i) qualify generally to do business in any jurisdiction
        where it would not otherwise be required to qualify but for this
        subsection, (ii) subject itself to taxation in any such jurisdiction or
        (iii) consent to general service of process in any such jurisdiction;

             (v) notify each seller of such Registrable Securities and the
        managing underwriter or underwriters, at any time when a prospectus
        relating thereto is required to be delivered under the Securities Act,
        of the happening of any event as a result of which the prospectus
        included in such registration statement contains an untrue statement of
        a material fact or omits to state any fact required to be stated therein
        to make the statements therein not misleading in the light of the
        circumstances then existing, and, at the request of any such seller, the
        Company shall prepare a supplement or amendment to such prospectus so
        that, as thereafter delivered to the purchasers of such Registrable
        Securities, such prospectus shall not contain an untrue statement of a
        material fact or omit to state any fact required to be stated therein to
        make the statements therein not misleading in the light of the
        circumstances then existing;

             (vi) cause all such Registrable Securities to be listed on each
        securities exchange on which similar securities issued by the Company
        are then listed and, if not so listed, to be listed on the NASD
        automated quotation system;

             (vii)      provide a transfer agent and registrar for all such
        Registrable Securities not later than the effective date of such
        registration statement;

             (viii) enter into such customary agreements (including underwriting
        agreements in customary form) and take all such other actions as the
        holders of a majority of the Registrable Securities being sold or the
        underwriters, if any, reasonably request in order

                                        8

        to expedite or facilitate the disposition of such Registrable
        Securities (including effecting a stock split or a combination of
        shares);

             (ix) make available for inspection by any seller of Registrable
        Securities, any underwriter participating in any disposition pursuant to
        such registration statement and any attorney, accountant or other agent
        retained by any such seller or underwriter, all financial and other
        records, pertinent corporate documents and properties of the Company,
        and cause the Company's officers, directors, employees and independent
        accountants to supply all information reasonably requested by any such
        seller, underwriter, attorney, accountant or agent in connection with
        such registration statement;

             (x) otherwise use its best efforts to comply with all applicable
        rules and regulations of the Securities and Exchange Commission, and
        make available to its security holders, as soon as reasonably
        practicable, an earnings statement covering the period of at least
        twelve months beginning with the first day of the Company's first full
        calendar quarter after the effective date of the registration statement,
        which earnings statement shall satisfy the provisions of Section 11(a)
        of the Securities Act and the rules and regulations promulgated
        thereunder;

             (xi) obtain a cold comfort letter from the Company's independent
        public accountants in customary form and covering such matters of the
        type customarily covered by cold comfort letters as the holders of a
        majority of the Registrable Securities being sold reasonably request
        (provided that such Registrable Securities constitute at least 10% of
        the securities covered by such registration statement); and

             (xii) if any such registration or comparable statement refers to
        any holder of Funds' Registrable Securities by name or otherwise as the
        holder of any securities of the Company and if in its sole and exclusive
        judgment, such holder is or might be deemed to be a controlling person
        of the Company, such holder shall have the right to require (i) the
        insertion therein of language, in form and substance satisfactory to
        such holder and presented to the Company in writing, to the effect that
        the holding by such holder of such securities is not to be construed as
        a recommendation by such holder of the investment quality of the
        Company's securities covered thereby and that such holding does not
        imply that such holder shall assist in meeting any future financial
        requirements of the Company or (ii) in the event that such reference to
        such holder by name or otherwise is not required by the Securities Act
        or any similar federal statute then in force, the deletion of the
        reference to such holder; PROVIDED

                                        9

        that with respect to this clause (ii) such holder shall furnish to the
        Company an opinion of counsel to such effect, which opinion and counsel
        shall be reasonably satisfactory to the Company.

        (b) Each seller of Registrable Securities agrees that, upon receipt of
any notice from the Company of the happening of any event of the type described
in clause (v) of Section 5(a) hereof, such seller shall forthwith discontinue
disposition of such Registrable Securities covered by such registration
statement or related prospectus until such seller's receipt of the copies of the
supplemental or amended prospectus contemplated by clause (v) of Section 5(a)
hereof, and, if so directed by the Company, such seller will deliver to the
Company (at the Company's expense) all copies, other than permanent file copies
then in such seller's possession, of the prospectus covering such Registrable

of Section 5(a) hereof and including the date when each seller of Registrable

prospectus contemplated by clause (v) of Section 5(a) hereof.

        (c) Each seller of Registrable Securities agrees to provide the Company,
upon receipt of its request, with such information about such seller to enable
the Company to comply with the requirements of the Securities Act and to execute
such certificates as the Company may reasonably request in connection with such
information and otherwise to satisfy any requirements of law.

covered by such registration for the reasonable fees (not exceeding, in the
aggregate, $25,000 for each registration) and disbursements of one counsel
chosen by the holders of a majority of the Funds' Registrable Securities.

        (c) To the extent Registration Expenses are not required to be paid by
the Company, each holder of securities included in any registration hereunder
shall pay those Registration Expenses allocable to the registration of such
holder's securities so included, and any Registration Expenses not so allocable

proportion to the aggregate selling price of the securities to be so registered.

        7.   INDEMNIFICATION.

        (a) The Company agrees to indemnify, to the extent permitted by law,
each holder of Registrable Securities, its officers and directors or general and
limited partners and each Person who controls such holder (within the meaning of
the Securities Act) against any and all losses, claims, damages, liabilities and
expenses arising out of or based upon (i) any untrue or alleged untrue statement
of material fact contained in any registration statement, prospectus or
preliminary prospectus or any amendment thereof or supplement thereto or (ii)
any omission or alleged omission of a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light
of the circumstances then existing, and the Company will reimburse such Persons
for any legal or any other expenses reasonably incurred by it in connection with
investigating or defending any such loss, claim, liability, action or
proceeding; PROVIDED, that the Company shall not be liable to any Person in any
such case to the extent that any such loss, claim, damage, liability (or action
or proceeding in respect thereof) or expense arises out of or is based upon any
untrue statement or alleged untrue statement or omission or alleged omission
made in such registration statement or amendment or supplement thereto or in any
such preliminary, final or summary prospectus in reliance upon and in conformity
with written information with respect to such seller furnished to the Company by
such seller for use in the preparation thereof. In connection with an
underwritten offering, the Company shall indemnify such underwriters, their
officers and directors and each Person who controls such underwriters (within
the meaning of the Securities Act) to the same extent as provided above with
respect to the indemnification of the holders of Registrable Securities.

        (b) In connection with any registration statement in which a holder of
Registrable Securities is participating, each such holder shall furnish to the
Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration

                                       11

statement or prospectus and, to the extent permitted by law, shall indemnify the
Company, its directors and officers and each Person who controls the Company
(within the meaning of the Securities Act) against any losses, claims, damages,
liabilities and expenses resulting from any untrue or alleged untrue statement
of material fact contained in the registration statement, prospectus or
preliminary prospectus or any amendment thereof or supplement thereto or any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, but only to the extent
that such untrue statement or omission is contained in any information or
affidavit so furnished in writing by such holder; PROVIDED that the obligation
to indemnify shall be individual to each holder and shall be limited to the net
amount of proceeds received by such holder from the sale of Registrable
Securities pursuant to such registration statement.

        (c) Any Person entitled to indemnification hereunder shall (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification; PROVIDED, that the failure of the indemnified
party to give notice as provided herein shall not relieve the indemnifying party
of its obligations under the preceding subsections of this Section 7, except to
the extent that the indemnifying party is actually prejudiced by such failure to
give notice and (ii) unless in such indemnified party's reasonable judgment a
conflict of interest between such indemnified and indemnifying parties may exist
with respect to such claim, permit such indemnifying party to assume the defense
of such claim with counsel reasonably satisfactory to the indemnified party. If
such defense is assumed, the indemnifying party shall not be subject to any
liability for any settlement made by the indemnified party without its consent
(but such consent shall not be unreasonably withheld). An indemnifying party who
is not entitled to, or elects not to, assume the defense of a claim shall not be
obligated to pay the fees and expenses of more than one counsel for all parties
indemnified by such indemnifying party with respect to such claim, unless in the
reasonable judgment of any indemnified party, a conflict of interest may exist
between such indemnified party and any other of such indemnified parties With
respect to such claim.

        (d) The indemnification provided for under this Agreement shall remain
in full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director or controlling Person of such
indemnified party and shall survive the transfer of securities. The Company also
agrees to make such provisions, as are reasonably requested by any indemnified
party, for contribution to such party in the event the Company's indemnification
is unavailable for any reason.

        (e) Indemnification similar to that specified in the preceding
subsections of this Section 7 (with appropriate modifications) shall be given by
the Company and each seller of Registrable Securities with respect

                                       12

to any required registration or other qualification of securities under any
federal or state law or regulation or governmental authority other than the
Securities Act.

        (f) The obligations of the parties under this Section 7 shall be in
addition to any liability which any party may otherwise have to any other party.

        8. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Person may
participate in any registration hereunder which is underwritten unless such
Person (a) agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Person or Persons entitled hereunder
to approve such arrangements and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
required under the terms of such underwriting arrangements; PROVIDED that no
holder of Registrable Securities included in any underwritten registration shall
be required to make any representations or warranties to the Company or the
underwriters other than representations and warranties regarding such holder and
such holder's intended method of distribution.

        9. RULE 144. If the Company shall have filed a registration statement
pursuant to the requirements of Section 12 of the Exchange Act or a registration
statement pursuant to the requirements of the Securities Act, the Company
covenants that it will file the reports required to be filed by it under the
Securities Act and the Exchange Act and the rules and regulations promulgated
thereunder (or, if the Company is not required to file such reports, it will,
upon the request of any holder of Shares, make publicly available such
information), and it will take such further action as any holder may reasonably
request, all to the extent required from time to time to enable such holder to
sell Registrable Securities without registration under the Securities Act within
the limitation of the exemptions provided by (a) Rule 144 under the Securities
Act, as such Rule may be amended from time to time, or (b) any similar rule or
regulation hereafter adopted by the Securities and Exchange Commission. Upon the
request of any holder of Shares, the Company will deliver to such holder a
written statement as to whether it has complied with such requirements.
Notwithstanding anything contained in this Section 9, the Company may deregister
under Section 12 of the Exchange Act if it then is permitted to do so pursuant
to the Exchange Act and the rules and regulations promulgated thereunder.

        10.  MISCELLANEOUS.

        (a) NO INCONSISTENT AGREEMENTS. The Company shall not hereafter enter
into any agreement with respect to its securities which is inconsistent with or
violates the rights granted to the holders of Registrable Securities under this
Agreement.

                                       13

        (b) ADJUSTMENTS AFFECTING REGISTRABLE SECURITIES. The Company shall not
take any action, or permit any change to occur, with respect to its securities
which would materially and adversely affect the ability of the holders of
Registrable Securities to include such Registrable Securities in a registration
undertaken pursuant to this Agreement or which would materially and adversely
affect the marketability of such Registrable Securities in any such registration
(including effecting a stock split or a combination of shares).

        (c) REMEDIES. Any Person having any rights under any provision of this
Agreement shall be entitled to enforce such rights specifically, to recover
damages caused by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law. The parties hereto agree and
acknowledge that money damages may not be an adequate remedy for any breach of
the provisions of this Agreement and that any party may in its sole discretion
apply to any court of law or equity of competent jurisdiction (without posting
any bond or other security) for specific performance and for other injunctive
relief in order to enforce or prevent violation of the provisions of this
Agreement.

        (d) CONSENT TO AMENDMENTS. Except as otherwise expressly provided
herein, no modification, amendment or waiver or any provision of this Agreement
shall be effective against the Company or the holders of the Registrable
Securities unless such modification, amendment or waiver is approved in writing
by the Company, the holders of a majority of the Funds' Registrable Securities,
and with respect to any amendment materially and adversely affecting the rights
of the holders of the Executive Registrable Securities, the holders of a
majority of the Executive Registrable Securities. The failure of any party to
enforce any of the provisions of this Agreement shall not affect the right of
such party thereafter to enforce each and every provision of this Agreement in
accordance with its terms.

        (e) SUCCESSORS AND ASSIGNS. The provisions of this Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective successors and assigns; provided that the rights granted under this
Agreement to the holders of Registrable Securities may not be assigned by them
except as permitted by Section 4.6 of the Shareholders Agreement. In addition,
whether or not any express assignment has been made, the provisions of this
Agreement which are for the benefit of purchasers or holders of Registrable
Securities are also for the benefit of, and enforceable by, any subsequent
holder of Registrable Securities.

        (f) SEVERABILITY. Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not

                                              14

invalidate or render unenforceable such provisions in any other jurisdiction.

        (g) COUNTERPARTS. This Agreement may be executed in two or more
counterparts, and by different parties on separate counterparts, each of which
shall be deemed an original, but all of which shall constitute one and the same
agreement.

                      1997 REGISTRATION RIGHTS AGREEMENT

      This 1997 REGISTRATION RIGHTS AGREEMENT, dated as of April 11, 1997 (this
"Agreement"), is between Cal Dive International, Inc., a Minnesota corporation
(the "Company"), and Coflexip, a French corporation ("CSO").

                                   RECITALS

      CSO and the Company are parties to a Purchase Agreement, dated as of April
11, 1997 (the "Purchase Agreement"), pursuant to which CSO is purchasing
3,699,788 shares of the common stock of the Company, without par value the
("Common Stock"), as described in the Purchase Agreement. In order to induce CSO
to enter into the Purchase Agreement, the Company has agreed to provide the
registration rights set forth in this Agreement.

      The execution and delivery of this Agreement is a condition precedent to
the obligation of CSO to accept Common Stock from the Company and the Selling
Shareholders pursuant to the Purchase Agreement and to enter into the 1997
Shareholders Agreement.

                                    AGREEMENT

      NOW THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, receipt of which is
hereby acknowledged, the parties hereto agree as follows:

      1. Definitions. (a) Unless otherwise defined herein, terms defined in the
Purchase Agreement are used herein as defined therein. For purposes of this
Agreement, the following terms have the meanings set forth below:

      "CSO Registrable Securities" means (i) any Common Stock issued by the
Company or purchased by CSO from the Selling Securityholders under the Purchase
Agreement, and (ii) any other Common Stock acquired by CSO, including, without
limitation, any Common Stock issued or issuable with respect to the Common Stock
referred to in clause (i) above by way of a stock dividend or stock split, or in
connection with a combination of shares, recapitalization, merger,
consolidation, reorganization or similar event.

      "Public Offering" means any sale of capital stock of the Company to the
public pursuant to an effective registration statement filed under the
Securities Act.

      "Registrable Securities" means the CSO Registrable Securities, Executive
Registrable Securities and the Funds' Registrable Securities (as the latter two
terms are defined in the Registration Rights Agreement dated January 12, 1995
between, among others, the Company, the Funds and the Executives (the "1995
Registration Agreement")). As to any particular Registrable Securities, such
securities shall cease to be Registrable Securities when they have been
distributed to the public pursuant to an offering registered under the
Securities Act or sold to the public through a broker, dealer, or market maker
in compliance with Rule 144 under the Securities Act (or any similar rule then
in force).

      "Shareholders Agreement" means the 1997 Shareholders Agreement among CSO,
the Company, the Executives and the Funds dated as of the date hereof.

                                       -1-

      2.    DEMAND REGISTRATIONS.

      (a) REQUEST FOR REGISTRATION. At any time, and from time to time, after
the earlier of (i) January 12, 2000 or (ii) a Public Offering, CSO or the
holders of the CSO Registrable Securities owning at least 25% of the CSO
Registrable Securities then outstanding may request registration under the
Securities Act of all or part of the CSO Registrable Securities. Within ten days
after receipt of any such request (which shall specify the amount of CSO
Registrable Securities to be registered), the Company shall give written notice
of such requested registration to all other holders of Registrable Securities
and shall include in such registration all Registrable Securities with respect
to which the Company has received written requests for inclusion therein within
15 days after the receipt of the Company's notice. All registrations requested
pursuant to this Section 2(a) are referred to herein as "Demand Registrations."

      (b) DEMAND REGISTRATIONS. The holders of the CSO Registrable Securities
are entitled to request and have effected up to three (3) Demand Registrations,
PROVIDED, that at the time of such request the holders of CSO Registrable
Securities own, in the aggregate, not less than 5% of the total outstanding
shares of Common Stock. A registration will not count as one of the permitted
Demand Registrations until it has become effective, and a registration initiated
as one of the Demand Registrations will not count as one of the permitted Demand
Registrations unless the holders of the CSO Registrable Securities are able to
register and sell at least 50% of the CSO Registrable Securities requested by
such holders to be included in such registration. All Demand Registrations shall
be underwritten registrations.

      (c) PRIORITY ON DEMAND REGISTRATIONS. The Company shall not include in any
Demand Registration any securities which are not Registrable Securities without
the prior written consent of the holders of a majority of the CSO Registrable
Securities. If in connection with a Demand Registration the managing
underwriters advise the Company and the holders of Registrable Securities in
writing that in their opinion the number of Registrable Securities and, if
permitted hereunder, other securities requested to be included in such offering,
exceeds the number of Registrable Securities and other securities, if any, which
can be sold in an orderly manner in such offering within a price range
acceptable to the holders of a majority of the CSO Registrable Securities, the
Company shall include in such registration (i) first, the Registrable Securities
requested to be included in such registration, allocated pro rata among the
Funds, the holders of CSO Registrable Securities and the Executives based on the
number Registrable Securities owned, in the aggregate, by the Funds, the holders
of CSO Registrable Securities and the Executives, respectively (with the
Registrable Securities which are included in the registration for the Funds, the
holders of CSO Registrable Securities and the Executives being allocated among
the holders within each such group pro rata based on the number of Registrable
Securities owned by each holder within the group or in such other manner as the
holders within each group shall otherwise agree), and (ii) second, other
securities requested to be included in such registration.

      (d) RESTRICTIONS ON DEMAND REGISTRATIONS. The Company shall not be
obligated to effect any Demand Registration within six months after (i) the
effective date of a previous Demand Registration, (ii) the effective date of an
S-3 Registration (as defined in Section 4(a) hereof), or (iii) a registration in
which the holders of CSO Registrable Securities were given piggyback rights
pursuant to Section 3 and in which there was no reduction in the number of CSO
Registrable Securities requested to be included. The Company may postpone for up
to 90 days the filing or the effectiveness of a registration statement for a
Demand Registration if the Company and the holders of a majority of the CSO
Registrable Securities agree that such Demand Registration would reasonably be
expected to have a material adverse effect on any proposal or plan by the
Company or any of its Subsidiaries to engage in any acquisition of assets (other
than in the ordinary course of business) or any merger, consolidation, tender
offer or similar transaction; PROVIDED, that in such event, the holders of the
CSO Registrable Securities requesting such 

                                      -2-
<PAGE>
Demand Registration shall be entitled to withdraw such request and, if such
request is withdrawn, such Demand Registration shall not count as a Demand
Registration.

      (e) SELECTION OF UNDERWRITERS. The holders of a majority of the CSO
Registrable Securities included in any Demand Registration shall have the right
to recommend the investment banker(s) and manager(s) to administer the offering,
subject to the approval of the Company, which shall not be unreasonably
withheld, delayed or conditioned.

      (f) OTHER REGISTRATION RIGHTS. Except as provided in this Agreement and
the 1995 Registration Agreement, the Company shall not grant to any Person the
right to require the Company to register any equity securities of the Company,
or any securities convertible or exchangeable into or exercisable for such
securities, without the prior written consent of the holders of a majority of
the CSO Registrable Securities; PROVIDED, that the Company may grant rights to
other Persons who agree to be bound by the provisions of Section 8(d) of this
Agreement or enter into a comparable agreement with the Company of which the
holders of CSO Registrable Shares are a third-party beneficiary to (i)
participate in Piggyback Registrations so long as such rights are subordinate to
the rights of the holders of CSO Registrable Securities with respect to such
Piggyback Registrations and (ii) request registrations so long as the holders of
CSO Registrable Securities are entitled to participate in any such registrations
with such Persons pro rata on the basis of the number of shares owned by such
Persons and such participating holders of CSO Registrable Securities (assuming
for this purpose that all shares owned by all participating holders of CSO
Registrable Securities are aggregated, on the one hand, and all shares owned by
all other Persons participating in such Registration are aggregated, on the
other hand).

      (g) REGISTRATION STATEMENT FORM. If any Demand Registration which is
proposed by the Company to be effected by the filing of a registration statement
on Form S-3 (or any successor or similar short-form registration statement)
shall be in connection with an underwritten public offering, and if the managing
underwriter shall advise the Company in writing that, in its opinion, the use of
another form of registration statement is of material importance to the success
of such proposed offering, then such registration shall be effected on such
other form.

      (h) EFFECTIVE REGISTRATION STATEMENT. A Demand Registration will not be
deemed to have been effected unless it has become effective; PROVIDED that if
within 180 days after it has become effective, the offering of CSO Registrable
Securities pursuant to such registration is interfered with by any stop order,
injunction or other order or requirement of the Securities and Exchange
Commission or other governmental agency or court, such registration will be
deemed not to have been effected.

      3.    PIGGYBACK REGISTRATIONS.

      (a) RIGHT TO PIGGYBACK. Whenever the Company proposes to register any of
its securities under the Securities Act (other than pursuant to a Demand
Registration or S-3 Registration requested by holders of CSO Registrable
Securities) and the registration form to be used may be used for the
registration of CSO Registrable Securities (a "Piggyback Registration"), the
Company shall give prompt written notice (in any event within three business
days after its receipt of notice of any exercise of demand registration rights
other than under this Agreement) to all holders of CSO Registrable Securities of
its intention to effect such a registration and shall include in such
registration all CSO Registrable Securities with respect to which the Company
has received written requests for inclusion therein within 15 days after such
holder's receipt of the Company's notice.

                                      -3-
<PAGE>
      (b) PIGGYBACK NOT A DEMAND REGISTRATION. The exercise by holders of CSO
Registrable Securities of their rights under this Section 3 shall not constitute
a Demand Registration under Section 2 hereof.

      (c) PRIORITY ON PRIMARY REGISTRATIONS. If a Piggyback Registration is an
underwritten primary registration on behalf of the Company, and the managing
underwriters advise the Company and the holders of Registrable Securities in
writing that in their opinion the number of securities requested to be included
in such registration exceeds the number which can be sold in an orderly manner
in such offering within a price range acceptable to the Company, the Company
shall include in such registration (i) first, the securities the Company
proposes to sell, (ii) second, the Registrable Securities requested to be
included in such registration, allocated pro rata among the Funds, the holders
of CSO Registrable Securities and the Executives based on the number Registrable
Securities owned, in the aggregate, by the Funds, the holders of CSO Registrable
Securities and the Executives, respectively (with the Registrable Securities
which are included in the registration for the Funds, the holders of CSO
Registrable Securities and the Executives being allocated among the holders
within each such group pro rata based on the number of Registrable Securities
owned by each holder within the group or in such other manner as the holders
within each group shall otherwise agree), and (iii) third, other securities
requested to be included in such registration.

      (d) PRIORITY ON SECONDARY REGISTRATIONS. If a Piggyback Registration is an
underwritten secondary registration on behalf of holders of the Company's
securities, and the managing underwriters advise the Company and the holders of
Registrable Securities in writing that in their opinion the number of securities
requested to be included in such registration exceeds the number which can be
sold in an orderly manner in such offering within a price range acceptable to
the holders of a majority of the securities initially requesting such
registration, the Company shall include in such registration (i) first, the
securities requested to be included therein by the holders requesting such
registration and the Registrable Securities requested to be included in such
registration, allocated pro rata among holders requesting the registration, the
Funds, the holders of CSO Registrable Securities and the Executives based on the
number Registrable Securities owned, in the aggregate, by the holders requesting
the registration, the Funds, the holders of CSO Registrable Securities and the
Executives, respectively (with the Registrable Securities which are included in
the registration for the holders requesting the registration, the Funds, the
holders of CSO Registrable Securities and the Executives being allocated among
the holders within each such group pro rata based on the number of Registrable
Securities owned by each holder within the group or in such other manner as the
holders within each group shall otherwise agree) and (ii) second, other
securities requested to be included in such registration.

      (e) OTHER REGISTRATIONS. If the Company has filed a registration statement
with respect to Registrable Securities pursuant to Section 2 or 4 or subject to
this Section 3, and if such registration statement has not been withdrawn or
abandoned, the Company shall not file or cause to be effected any other
registration of any of its equity securities or securities convertible or
exchangeable into or exercisable for its equity securities under the Securities
Act (except on Form S-8 or any successor form), whether on its own behalf or at
the request of any holder or holders of such securities, until a period of at
least six months has elapsed from the effective date of such previous
registration statement.

      4.    FORM S-3 REGISTRATIONS.

      (a) If the Company becomes eligible to use Form S-3 under the Securities
Act or a comparable successor form, the Company shall use its reasonable best
efforts to continue to qualify at all times for registration of its capital
stock on Form S-3 or such successor form. In such event, CSO or the
holders of CSO Registrable Securities owning at least 25% of the CSO Registrable
Securities then 

                                      -4-
<PAGE>
outstanding shall have the right, from time to time, to request and have
effected up to three (3) registrations of shares of CSO Registrable Securities
on Form S-3 or such successor form (which request shall specify the amount of
CSO Registrable Securities to be registered), PROVIDED, that, at the time of
such request, the holders of CSO Registrable Securities own, in the aggregate,
not less than 5% of the total outstanding shares of Common Stock. All
registrations requested pursuant to this Section 4(a) are referred to herein as
"S-3 Registrations." A registration will not count as one of the permitted S-3
Registrations until it has become effective. If so requested by any holder of
CSO Registrable Securities in connection with an S-3 Registration, the Company
shall take such steps as are required to register such holder's CSO Registrable
Securities for sale on a delayed or continuous basis under Rule 415 and shall
take such steps as are required to keep such registration effective until all of
such holder's CSO Registrable Securities registered thereunder are sold. S-3
Registrations need not be underwritten unless either the Company (if it includes
shares in the S-3 Registration pursuant to Section 4(b) hereof) or the holders
of a majority of the CSO Registrable Securities demanding the registration
request that it be underwritten.

      (b) USE OF ALTERNATE REGISTRATION STATEMENTS; PRIORITY IN S-3
REGISTRATIONS. At the Company's option, the Company may elect to include in an
S-3 Registration, Common Stock to be issued by the Company and, if required in
order to effect the registration of such securities, cause the registration to
be made pursuant to a registration statement on Form S-1 or S-2, which shall
count as one of the five S-3 Registrations. If in connection with an
underwritten S-3 Registration the managing underwriters advise the Company and
the holders of Registrable Securities in writing that in their opinion the
number of Registrable Securities and, if permitted hereunder, other securities
requested to be included in such offering, exceeds the number of Registrable
Securities and other securities, if any, which can be sold in an orderly manner
in such offering within a price range acceptable to the holders of a majority of
the CSO Registrable Securities, the Company shall include in such registration
(i) first, the Registrable Securities requested to be included in such
registration, allocated pro rata among the Funds, the holders of CSO Registrable
Securities and the Executives based on the number Registrable Securities owned,
in the aggregate, by the Funds, the holders of CSO Registrable Securities and
the Executives, respectively (with the Registrable Securities which are included
in the registration for the Funds, the holders of CSO Registrable Securities and
the Executives being allocated among the holders within each such group pro rata
based on the number of Registrable Securities owned by each holder within the
group or in such other manner as the holders within each group shall otherwise
agree), and (ii) second, other securities requested to be included in such
registration.

      (c) RESTRICTIONS ON S-3 REGISTRATIONS. The Company shall not be obligated
to effect any S-3 Registration within six months after (i) the effective date of
a previous Demand Registration, (ii) the effective date of a previous S-3
Registration hereof, or (iii) a registration in which the holders of CSO
Registrable Securities were given piggyback rights pursuant to Section 3 and in
which there was no reduction in the number of CSO Registrable Securities
requested to be included. The Company may postpone for up to 90 days the filing
or the effectiveness of a registration statement for an S-3 Registration if the
Company and the holders of a majority of the CSO Registrable Securities agree
that such S-3 Registration would reasonably be expected to have a material
adverse effect on any proposal or plan by the Company or any of its Subsidiaries
to engage in any acquisition of assets (other than in the ordinary course of
business) or any merger, consolidation, tender offer or similar transaction;
PROVIDED, that in such event, the holders of the CSO Registrable Securities
requesting such S-3 Registration shall be entitled to withdraw such request and,
if such request is withdrawn, such S-3 Registration shall not count as an S-3
Registration.

      (d)   SELECTION OF UNDERWRITERS.  In an underwriter is requested pursuant 
to Section 4(a) hereof, the holders of a majority of the CSO Registrable
Securities included in the S-3 Registration shall have the 

                                      -5-
<PAGE>
right to recommend the investment banker(s) and manager(s) to administer the
offering, subject to the approval of the Company which shall not be unreasonably
withheld, delayed or conditioned.

      (e) EFFECTIVE REGISTRATION STATEMENT. An S-3 Registration will not be
deemed to have been effected unless it has become effective; PROVIDED that if
within 180 days after it has become effective, the offering of CSO Registrable
Securities pursuant to such registration is interfered with by any stop order,
injunction or other order or requirement of the Securities and Exchange
Commission or other governmental agency or court, such registration will be
deemed not to have been effected.

      5. HOLDBACK AGREEMENTS. Each holder of CSO Registrable Securities agrees
not to effect any public sale or distribution of equity securities of the
Company, or any securities convertible into or exchangeable or exercisable for
such securities, during the seven days prior to and the 90-day period beginning
on the effective date of the first registration statement of the Company
declared effective under the Securities Act unless the underwriters managing the
related offering otherwise agree; PROVIDED, that the holders of the CSO
Registrable Securities shall not be so restricted unless comparable agreements
are entered into by each executive officer and director of the Company and each
holder of at least 2% (on a fully-diluted basis) of its equity securities, or
any securities convertible into or exchangeable or exercisable for such
securities, purchased from the Company at any time after the date hereof.

      6.    REGISTRATION PROCEDURES.

1934, as amended (the "Exchange Act"), and the rules and regulations promulgated
thereunder with respect to the disposition of all securities covered by such
registration statement during such period in accordance with the intended
methods of disposition by the sellers thereof disclosed to the Company by such
sellers or set forth in such registration statement;

            (iii) furnish to each seller of CSO Registrable Securities such
number of copies of such registration statement, each amendment and supplement

disposition in such jurisdictions of the CSO Registrable Securities owned by
such seller; PROVIDED that the Company shall not be required to (i) qualify
generally to do business in any jurisdiction where it would not otherwise be
required to qualify but for this subsection, or (ii) subject itself to taxation
in any such jurisdiction;

            (v) notify each seller of such CSO Registrable Securities and the
managing underwriter or underwriters, at any time when a prospectus relating
thereto is required to be delivered under the Securities Act, of the happening
of any event as a result of which the prospectus included in such registration
statement contains an untrue statement of a material fact or omits to state any
fact required to be stated therein to make the statements therein not misleading
in the light of the circumstances then existing, and, at the request of any such
seller, the Company shall prepare a supplement or amendment to such prospectus
so that, as thereafter delivered to the purchaser of such CSO Registrable
Securities, such prospectus shall not contain an untrue statement of a material
fact or omit to state any fact required to be stated therein to make the
statements therein not misleading in the light of the circumstances then
existing;

            (vi) cause all such CSO Registrable Securities to be listed on each
securities exchange (including the NASDAQ National Market) on which similar
securities issued by the Company are then listed and, if not so listed, to be
listed on the NASD automated quotation system;

            (vii) provide a transfer agent and registrar for all such CSO
Registrable Securities not later than the effective date of such registration
statement;

            (viii)enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the holders of
a majority of the CSO Registrable Securities being sold or the underwriters, if
any, reasonably request in order to expedite or facilitate the disposition of
such CSO Registrable Securities (including effecting a stock split or a
combination of shares);

            (ix) make available for inspection by any seller of CSO Registrable
Securities, any underwriter participating in any disposition pursuant to such
registration statement and any attorney, accountant or other agent retained by
any such seller or underwriter, all financial and other records, pertinent
corporate documents and properties of the Company, and cause the Company's
officers, directors, employees, attorneys and independent accountants to supply
all information reasonably requested (and not privileged in the case of
information from attorneys) by any such seller, underwriter, attorney,
accountant or agent in connection with such registration statement;

            (x) otherwise use its best efforts to comply with all applicable
rules and regulations of the Securities and Exchange Commission, and make
available to its security holders, as soon as reasonably practicable, an
earnings statement covering the period of at least twelve months beginning with
the first day of the Company's first full calendar quarter after the effective
date of the registration statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act and the rules and regulations
promulgated thereunder;

            (xi)  obtain for the benefit of the holders of CSO Registrable 
Securities included in the registration a cold comfort letter from the Company's
independent public accountants in customary form 

                                      -7-
<PAGE>
and covering such matters of the type customarily covered by cold comfort
letters as the holders of a majority of the CSO Registrable Securities being
sold reasonably request;

Securities included in the registration an opinion of counsel in customary form
and covering such matters of the type customarily covered by underwriters in an
underwritten public offering; and

            (xiii)if any such registration or comparable statement refers to any
holder of CSO Registrable Securities by name or otherwise as the holder of any
securities of the Company and if in its sole and exclusive judgment, such holder
is or might be deemed to be a controlling Person of the Company, such holder
shall have the right to require (A) the insertion therein of language, in form
and substance satisfactory to such holder and presented to the Company in
writing, to the effect that the holding by such holder of such securities is not
to be construed as a recommendation by such holder of the investment quality of
the Company's securities covered thereby and that such holding does not imply
that such holder shall assist in meeting any future financial requirements of
the Company or (B) in the event that such reference to such holder by name or
otherwise is not required by the Securities Act or any similar federal statute
then in force, the deletion of the reference to such holder; PROVIDED that with
respect to this clause (B) such holder shall furnish to the Company an opinion
of counsel to such effect, which opinion of counsel shall be reasonably
satisfactory to the Company.

      (b) Each seller of CSO Registrable Securities agrees that, upon receipt of
any notice from the Company of the happening of any event of the type described
in clause (v) of Section 6(a) hereof, such seller shall forthwith discontinue
disposition of such CSO Registrable Securities covered by such registration
statement or related prospectus until such seller's receipt of the copies of the
supplemental or amended prospectus contemplated by clause (v) of Section 6(a)
hereof, and, if so directed by the Company, such seller will deliver to the
Company (at the Company's expense) all copies, other than permanent file copies
then in such seller's possession, of the prospectus covering such CSO
Registrable Securities current at the time of receipt of such notice. In the
event the Company shall give any such notice, the period mentioned in clause
(ii) of Section 6(a) hereof shall be extended by the number of days during the
period from and including the date of the giving of such notice pursuant to

Registrable Securities shall have received the copies of the supplemental or
amended prospectus contemplated by clause (v) of Section 6(a) hereof.

Company, upon receipt of its request, with such information about such seller as
is necessary to enable the Company to comply with the requirements of the
Securities Act and to execute such certificates as the Company may reasonably
request in connection with such information and otherwise to satisfy any
requirements of law.

      7.    REGISTRATION EXPENSES.

Company's performance of or compliance with this Agreement, including all

                                      -8-
<PAGE>

S-3 Registration and each Piggyback Registration in which only the Company and
holders of CSO Registrable Securities participate, the Company shall reimburse
the holders of CSO Registrable Securities covered by such registration for the

majority of the CSO Registrable Securities requested to be included in such

Registrable Securities requested to be included in such registration, which
acceptance shall not be unreasonably withheld.

      8.    INDEMNIFICATION

      (a) The Company agrees to indemnify, to the extent permitted by law, each
holder of CSO Registrable Securities, its officers and directors, general and
limited partners, employees and agents and each Person who controls such holder
(within the meaning of the Securities Act or the Exchange Act) against any and
all losses, claims, damages, liabilities and expenses (including any amount paid
in settlement of any action, suit or proceeding or any claim asserted subject to
Section 8(c) below) arising out of or based upon (i) any untrue or alleged
untrue statement of material fact contained in any registration statement,
prospectus or preliminary prospectus or any amendment thereof or supplement
thereto, (ii) any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing or (iii) any violation by the Company
of the Securities Act or any rule or regulation thereunder in connection with
such registration, and the Company will reimburse such Persons for any legal or
any other expenses reasonably incurred by it in connection with investigating or
defending any such loss, claim, liability, action or proceeding or enforcing its
rights under this Section 8; PROVIDED, that the Company shall not be liable to
any Person in any such case to the extent that any such loss, claim, damage,
liability (or action or proceeding in respect thereof) or expense arises out of
or is based upon any untrue statement or alleged untrue statement or omission or
alleged omission made in such registration statement or amendment or supplement
thereto or in any such preliminary, final or summary prospectus in reliance upon
and in conformity with written information with respect to such seller furnished
to the Company by such seller expressly for use in the preparation thereof. In
connection with an underwritten offering, the Company shall indemnify such
underwriters, their officers and directors, general and limited partners,
employees and agents and each Person who controls such underwriters (within the
meaning of the Securities Act or the Exchange Act) to the same extent as
provided above with respect to the indemnification of the holders of CSO
Registrable Securities.

      (b) In connection with any registration statement in which a holder of CSO
Registrable Securities is participating, each such holder shall furnish to the
Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or
prospectus and, to the extent permitted by law, shall indemnify the Company, its
directors and officers and each Person who controls the Company (within the
meaning of the Securities Act) against any losses, claims, damages, liabilities
and expenses resulting from any untrue or alleged untrue statement of material
fact contained in the registration statement, prospectus or preliminary
prospectus or any amendment 

                                      -9-
<PAGE>
thereof or supplement thereto or any omission or alleged omission of a material
fact required to be stated therein or necessary to make the statements therein
not misleading, but only to the extent that such untrue statement or omission is
contained in any information or affidavit so furnished in writing by such holder
expressly for use in such Registration Statement, PROVIDED that the obligation
to indemnify shall be individual to each holder and shall be limited to the net
amount of proceeds received by such holder from the sale of CSO Registrable
Securities pursuant to such registration statement.

      (c) Any Person entitled to indemnification hereunder shall (i) give prompt
written notice to the indemnifying party of any claim with respect to which it
seeks indemnification; PROVIDED, that the failure of the indemnified party to
give notice as provided herein shall not relieve the indemnifying party of its
obligations under the preceding subsections of this Section 8, except to the
extent that the indemnifying party is actually prejudiced by such failure to
give notice and (ii) unless in such indemnified party's reasonable judgment a
conflict of interest between such indemnified and indemnifying parties may exist
with respect to such claim, permit such indemnifying party to assume the defense
of such claim with counsel reasonably satisfactory to the indemnified party. If
such defense is assumed, the indemnifying party shall not be subject to any
liability for any settlement made by the indemnified party without its consent
(but such consent shall not be unreasonably withheld). An indemnifying party who
is not entitled to, or elects not, to assume the defense of a claim shall not be
obligated to pay the fees and expenses of more than one counsel for all parties
indemnified by such indemnifying party with respect to such claim, unless in the
reasonable judgment of any indemnifying party, a conflict of interest may exist
between such indemnified party and any other of such indemnified parties with
respect to such claim.

      (d) The indemnification provided for under this Agreement shall remain in
full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director or controlling Person of such
indemnified party and shall survive the transfer of securities. If the
indemnification provided for in this Section 8 for any reason is held by a court
of competent jurisdiction to be unavailable to an indemnified party in respect
of any losses, claims, damages, expenses or liabilities referred to therein,
then each indemnifying party under this Section 8, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages, expenses or
liabilities in such proportion as is appropriate to reflect (i) the relative
benefits received by the Company, the holders of Registrable Securities or other
securities sold in an offering (the "Selling Holders") and the underwriters from
the offering, (ii) the relative fault of the Company, the Selling Holders and
the underwriters in connection with the statements or omissions which resulted
in such losses, claims, damages, expenses or liabilities, and (iii) any other
relevant equitable considerations. The relative benefits received by the
Company, the Selling Holders and the underwriters shall be deemed to be in the
same respective proportions as the net proceeds from the offering (before
deducting expenses) received by the Company and the Selling Holders and the
underwriting discount received by the underwriters, in each case as set forth in
the table on the cover page of the applicable prospectus, bear to the aggregate
public offering price of the securities sold in the offering. The relative fault
of the Company, the Selling Holders and the underwriters shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company, the Selling Holders or the
underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The Company
and the holders of the CSO Registrable Securities agree that it would not be
just and equitable if contribution pursuant to this Section 8 were determined by
pro rata or per capita allocation or by any other method of allocation which
does not take account of the equitable considerations referred to in this
subsection. In no event, however, shall a Selling Holder be required to
contribute any amount under this Section 8 in excess of the net amount of
proceeds received by such Selling Holder from its sale of securities under such
registration statement. No Person found guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) 

                                      -10-
<PAGE>
of the Securities Act) shall be entitled to contribution from any Person who was
not guilty of such fraudulent misrepresentation.

      (e) Indemnification similar to that specified in the preceding subsections
of this Section 8 (with appropriate modifications) shall be given by the Company
and each seller of CSO Registrable Securities with respect to any required
registration or other qualification of securities under any federal or state law
or regulation or governmental authority other than the Securities Act.

      (f) The obligations of the parties under this Section 8 shall be in
addition to any liability which any party may otherwise have to any other party.

      9. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Person may participate
in any registration hereunder which is underwritten unless such Person (a)
agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Person or Persons entitled hereunder
to approve such arrangements and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
required under the terms of such underwriting arrangements; PROVIDED that no
holder of CSO Registrable Securities included in any underwritten registration
shall be required to make any representations or warranties to the Company or
the underwriters other than representations and warranties regarding such holder
and such holder's intended method of distribution.

      10.   RULES 144 AND 144A.

      (a) RULE 144. The Company covenants that it will file the reports required
to be filed by it under the Securities Act and the Exchange Act and the rules
and regulations promulgated thereunder (or, if the Company is not required to
file such reports, it will, upon the request of any holder of CSO Registrable
Securities, make publicly available such information), and it will take such
further action as any holder may reasonably request, all to the extent required
from time to time to enable such holder to sell CSO Registrable Securities
without registration under the Securities Act within the limitation of the
exemptions provided by (i) Rule 144 under the Securities Act, as such Rule may
be amended from time to time, or (ii) any similar rule or regulation hereafter
adopted by the Securities and Exchange Commission. Upon the request of any
holder of CSO Registrable Securities from time to time, the Company will deliver
to any such holder (i) a written statement as to whether it has complied with
such requirements, and (ii) at the Company's expense, an opinion of the
Company's counsel as to the availability of an exemption from registration in
connection with a proposed transfer of CSO Registrable Securities by such
holder. Notwithstanding anything contained in this Section 10, the Company may
deregister under Section 12 of the Exchange Act if it then is permitted to do so
pursuant to the Exchange Act and the rules and regulations promulgated
thereunder.

      (b) RULE 144A. The Company shall, at all times during which it is neither
subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, nor exempt from reporting pursuant to Rule 12g3-2(b) under the Exchange
Act, promptly upon the written request of any holder of CSO Registrable
Securities, provide in writing to such holder and to any prospective transferee
of any of the CSO Registrable Securities of such holder the information
concerning the Company described in Rule 144A(d)(4) under the Securities Act
("Rule 144A Information"). The Company also shall, upon the written request of
any such holder, cooperate with and assist such holder or any member of the
National Association of Securities Dealers, Inc. PORTAL system in applying to
designate and thereafter maintain the eligibility of the Common Stock for
trading through PORTAL. The Company's obligations under this Section 10(b) shall
at all times be contingent upon receipt from the prospective transferees of CSO
Registrable Securities of a written agreement to take all reasonable precautions
to safeguard the Rule 144A 

                                      -11-

transferee in evaluation the purchase of the CSO Registrable Securities.

any agreement with respect to its securities which is inconsistent with or
violates the rights granted to the holders of CSO Registrable Securities under
this Agreement.

      (b) ADJUSTMENTS AFFECTING CSO REGISTRABLE SECURITIES. The Company shall
not take any action, or permit any change to occur, with respect to its
securities which would materially and adversely affect the ability of the
holders of CSO Registrable Securities to include such CSO Registrable Securities
in a registration undertaken pursuant to this Agreement or which would
materially and adversely affect the marketability of such CSO Registrable
Securities in any such registration (including affecting a stock split or a
combination of shares).

      (c) REMEDIES. Any Person having any rights under any provision of this
Agreement shall be entitled to enforce such rights specifically, to recover
damages caused by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law. The parties hereto agree and
acknowledge that money damages may not be an adequate remedy for any breach of
the provisions of this Agreement and that any party may in its sole discretion
apply to any court of law or equity of competent jurisdiction (without posting
any bond or other security) for specific performance and for other injunctive
relief in order to enforce or prevent violation of the provisions of this
Agreement.

      (d) CONSENT TO AMENDMENTS. Except as otherwise expressly provided herein,
no modification, amendment or waiver of any provision of this Agreement shall be
effective against the Company or the holders of the CSO Registrable Securities
unless such modification, amendment or waiver is approved in writing by the
Company and the holders of a majority of the CSO Registrable Securities. The
failure of any party to enforce any of the provisions of this Agreement shall
not affect the right of such party thereafter to enforce each and every
provision of this Agreement in accordance with its terms.

      (e) SUCCESSORS AND ASSIGNS. The provisions of this Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their

(including without limitation Section 8(b) hereof) if requested by the Company.

      (f) SEVERABILITY. Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provisions in any
other jurisdiction.

      (g) COUNTERPARTS. This Agreement may be executed in two or more
counterparts, and by different parties on separate counterparts, each of which

                  Ordinary Course of Business;

            (viii) neither the Company nor any of its Subsidiaries has entered
                  into any transaction or made or entered into any Contract
                  which by reason of its size, subject matter or otherwise is
                  not in the Ordinary Course of Business ;

            (ix)  neither the Company nor any of its Subsidiaries has suffered
                  one or more Extraordinary Losses;

            (x)   neither the Company nor any of its Subsidiaries has made any
                  investments in or loans to, or paid any material fees or
                  expenses to, or entered into or modified any Contract with any
                  of the Shareholders or any other respective Affiliates other
                  than inter-company arrangements between the Company and its
                  Subsidiaries; and

            (xi)  neither the Company nor any of its Subsidiaries has agreed or
                  committed to do anything set forth in this Section 6F.

      6G. TAX MATTERS. The Company and each of its Subsidiaries have filed in a
timely manner all tax returns which they are required to file other than those
which, individually or in the aggregate, would not have a Material Adverse
Effect; and such returns are true and correct in all material respects. The
Company and each of its Subsidiaries have timely paid all taxes owed by them (or
have made provision for the payment thereof on the Latest Balance Sheet) and
have withheld and paid over all Taxes which they are obligated to withhold from
amounts owing to any employee, creditor or other Person. No unresolved
deficiencies or additions to Taxes have been proposed, asserted or assessed
against the Company or any of its Subsidiaries, and the assessment of any
additional Taxes for periods for which returns have been filed is not expected
to exceed the recorded liability therefor on the Latest Balance Sheet. Neither
the Company nor any of its Subsidiaries have incurred any liability for Taxes
from the date of the Latest Balance Sheet except for Taxes incurred in the
ordinary course of business consistent with past practice. The federal income
tax returns of the Company and its Subsidiaries have been audited for all tax
years through 1991; there are no pending 

                                       15
<PAGE>
federal or state tax audits being conducted with respect to the Company or any
of its Subsidiaries; and there are no material unresolved questions or claims
concerning the Company's or any of its Subsidiaries' tax liability, except as
described on SCHEDULE 6G.

      6H. LITIGATION. There are no Legal Proceedings pending or, to the best of
the Company's knowledge, threatened against or affecting the Company or any of
its Subsidiaries or the business or assets of the Company or any of its
Subsidiaries, that if adversely determined, could reasonably be expected to have
a material adverse effect on the Company's ability to perform its obligations
under this Agreement or any of the Seller Documents or any action taken or to be
taken by the Company or any of its Subsidiaries in connection with the
consummation of the transactions contemplated hereby or thereby. SCHEDULE 6H
sets forth a list of all Legal Proceedings pending or, to the knowledge of the
Company, threatened against or involving the Company or any of its Subsidiaries
or any business or assets of the Company or any of its Subsidiaries, at law, in
equity or admiralty, or otherwise which, if determined adversely to the Company
or any of its Subsidiaries, could reasonably be expected to result in a
liability to the Company or any of its Subsidiaries in excess of $100,000. There
is no outstanding or, to the knowledge of the Company, threatened Order of any
Governmental Body against, involving or naming the Company or any of its
Subsidiaries or involving any of their respective businesses or assets. SCHEDULE
6H sets forth a list of all Legal Proceedings pending or contemplated in which
the Company or any of its Subsidiaries is the plaintiff or claimant. Some of the
Legal Proceedings identified in SCHEDULE 6H against the Company or its
Subsidiaries may be subject to punitive damage awards . Since punitive damage
awards are uninsured exposures, an adverse result in any of the cases listed on
SCHEDULE 6H could have a Material Adverse Effect on the Company.

      6I. REAL PROPERTY. (a) Neither the Company nor any of its Subsidiaries
owns any real property. SCHEDULE 6I contains a correct and complete schedule of
the documents comprising all leases, subleases, licenses, rights of way or other
Contracts for the use or occupancy of any real property ("ONSHORE REAL PROPERTY
LEASES") or the exploration, development or exploitation of oil or gas
properties by the Company or any of its Subsidiaries ("OFFSHORE REAL PROPERTY
LEASES"). Neither the Company nor any of its Subsidiaries is a party to any
lease, sublease, license or other agreement for the use or occupancy of any
onshore or offshore real property other than the Onshore or Offshore Real
Property Leases. There exists no material reciprocal easement or operating
Contracts relating to the Offshore Real Property Leases between the Company
and/or any of its Subsidiaries and any third party. Except as set forth on
SCHEDULE 6I, neither the Company nor any of its Subsidiaries has assigned,
sublet, mortgaged or otherwise encumbered in any respect whatsoever its
leasehold estate under the Onshore or Offshore Real Property Leases. Except as
set forth on SCHEDULE 6I, neither the Company nor any of its Subsidiaries owns
or holds, or is obligated under or a party to, any option, right of first
refusal or other contractual right to purchase, acquire, sell, assign or dispose
of any real estate or any portion thereof or interest therein.

      (b) Each of the Onshore and Offshore Real Property Leases is a valid and
binding obligation enforceable against the Company and/or any of its
Subsidiaries which is a party thereto and, to the knowledge of the Company,
against each other party thereto in accordance with its terms, and there is no
default under any of the Onshore and Offshore Real Property Leases by the
Company, any of its Subsidiaries or, to the knowledge of the Company, by any
other party thereto and, to the knowledge of the Company, no event has occurred
that with the lapse of time or the giving of notice or both would constitute a
default thereunder, except for such defaults or events which would not have a
Material Adverse Effect. No previous or current party to the Onshore or Offshore
Real Property Leases has given written notice of or made a claim against the
Company or any of its Subsidiaries with respect to any breach or default
thereunder which remains uncured or otherwise in existence as of the date
hereof. To the knowledge of the Company, each of the Onshore or Offshore Real
Property Leases covers the entire estate it purports to cover and, entitles the

                                       16
<PAGE>
Company and its Subsidiaries to the use, occupancy and possession of the real
property or the exploration, development or exploitation of the oil or gas
properties, as applicable, specified in the Onshore or Offshore Real Property
Leases and for the purposes such property is now being used by the Company and
its Subsidiaries. To the knowledge of the Company, neither the Company nor any
of its Subsidiaries is engaged in any "slant drilling" across the properties of
any other Person or otherwise engaged in any activities which violate the
property rights of any other Person. Complete and correct copies of the Onshore
or Offshore Real Property Leases, together with all amendments, modifications,
supplements or side letters affecting the obligations of any party thereunder
have been delivered to the Purchaser. To the knowledge of the Company, the
property which is subject to the Onshore and Offshore Real Property Leases
complies with all applicable Laws, except for such failure to comply which would
not have a Material Adverse Effect. No notice of violation of any such Law has
been received by the Company or any of its Subsidiaries and, to the knowledge of
the Company, no such notice has been issued by any Governmental Body with
respect to such property.

      (c) No portion of property covered by an Onshore Real Property Lease
("Onshore Property") is dependent for its access, operation or utility on any
land, building or other improvement not part of the Onshore Property. The
Onshore Property has direct, unobstructed access, both pedestrian and vehicular,
to public rights of way. All material utility systems required in connection
with use, occupancy and operation of the Onshore Property are supplied directly
to the Onshore Property by facilities of public utilities, are sufficient for
their present purposes, are fully operational and in working order, and are
benefitted by customary utility easements providing for the continued use and
maintenance of such systems.

      (d) EXHIBIT K contains a true and correct copy of the estimate dated
December 31,1995, prepared by Miller & Lents, Ltd., independent petroleum
engineers ("MILLER & LENTS"), of the proved developed reserves and future net
revenue attributable to interests in properties located offshore Texas and
offshore Louisiana of ERT (the "RESERVES REPORT"). The historical information
underlying the estimates of the reserves of ERT supplied by the Company to
Miller & Lents, for the purposes of preparing the Reserve Report, including,
without limitation, production volumes, sales prices for production, contractual
pricing provisions under oil or gas sales or marketing contracts or under
hedging arrangements, costs of operations and development, and working interest
and revenue information relating to ERT's ownership interests in properties, was
true and correct in all material respects on the date of such Reserve Report;
the estimates of future capital expenditures and other future exploration and
development costs supplied to Miller & Lents were prepared in good faith and
with a reasonable basis; the information provided by Miller & Lents for purposes
of preparing the Reserve Report was prepared in accordance with customary
industry practices; to the best of the Company's knowledge, Miller & Lents was,
as of the date of the Reserve Report prepared by it, and are, as of the date
hereof, independent petroleum engineers with respect to the Company; and other
than normal production of reserves and intervening spot market product price
fluctuations, the Company is not aware of any facts or circumstances that would
result in a materially adverse change in the reserves in the aggregate, or the
aggregate present value of future net cash flows therefrom, as reflected in the
Reserve Report except as indicated in EXHIBIT K .

      6J. VESSELS. (a) The Company and its Subsidiaries do not own or operate
any vessels other than those listed on SCHEDULE 6J (collectively, the

any of the Vessels been sold, chartered or otherwise transferred to any Person
in violation of Law.

                                       17

further acts as may be reasonably necessary or desirable for the implementation

attorneys' fees and the fees of Simmons & Company International, incurred in
connection with the negotiation of this Agreement, the performance of its

reason of any breach of any provision of this Agreement and to exercise all
other rights granted by law.

      12C. ENTIRE AGREEMENT; AMENDMENTS AND WAIVERS. This Agreement (including
the exhibits hereto) represents the entire understanding and agreement between
the parties hereto with respect to the subject matter hereof and can be amended,
supplemented or changed, and any provision hereof can be waived, only by written
instrument making specific reference to this Agreement signed by the party
against whom enforcement of any such amendment, supplement, modification or
waiver is sought. No action taken pursuant to this Agreement, including without
limitation, any investigation by or on behalf of any party, shall be deemed to
constitute a waiver by the party taking such action of compliance with any
representation, warranty, covenant or agreement contained herein. The waiver by
any party hereto of a breach of any provision of this Agreement shall not
operate or be construed as a further or continuing waiver of such breach or as a
waiver of any other or subsequent breach. No failure on the part of any party to
exercise, and no delay in exercising, any right, power or remedy hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of such
right, power or remedy by such party preclude any other or further exercise
thereof or the exercise of any other right, power or remedy. All remedies
hereunder are cumulative and are not exclusive of any other remedies provided by
law.

      12D. SURVIVAL OF REPRESENTATION AND WARRANTIES; INDEMNIFICATION. (a) The
representations and warranties contained in this Agreement or any of the
documents delivered at Closing pursuant to Sections 2C, 2N, 3C or 3K shall
survive the execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby and continue in full force and effect,
regardless of any investigation made by the Purchaser or on its behalf, for a
period of three (3) years after the Closing Date ; PROVIDED, HOWEVER, 

                                       33
<PAGE>
that (i) the representations and warranties of the Company contained in the
first and second sentences of Section 6C, the last sentence of Section 6E,
Section 6G, paragraph (b) of Section 6J, the first sentence of paragraph (c) of
Section 6K, the second sentence of Section 6L and Section 6N shall continue in
full force and effect until 60 days after any applicable statute of limitations
(taking into account any waiver or tolling thereof) with respect to any Legal
Proceeding which may arise thereunder or relate thereto shall have run; (ii) the
representations and warranties of the Company contained in Section 6Q shall
continue in full force and effect for a period of five (5) years after Closing
Date; (iii) the representations and warranties of the Shareholders contained in
the first sentence of Section 7A and the first, second and third sentences of
Section 7B and (iv) the representations and warranties of the Purchaser
contained in the first and second sentences of Section 8B and in Section 5 of
the ROV Agreement shall continue in full force and effect until 60 days after
any applicable statute of limitations (taking into account any waiver or tolling
thereof) with respect to any Legal Proceeding which may arise thereunder or
relate thereto shall have run. To the extent the survival periods specified
herein exceed an applicable statute of limitations, the provisions of this
Section 12D(a) shall constitute a waiver by the Company, the Shareholders or the
Purchaser, as applicable, of each such statute of limitations.

      (b) The Company hereby agrees to indemnify and hold harmless the Purchaser
and its directors, officers, employees, Affiliates, agents, successors and
assigns (collectively, the "PURCHASER INDEMNIFIED PARTIES") from and against:

            (i) subject to paragraph (a) of this Section 12D, any and all
losses, liabilities, obligations, damages, deficiencies, costs and expenses
("LOSSES") based upon, attributable to or resulting from any inaccuracy in or
breach of any representation or warranty on the part of the Company under this
Agreement or in any of the documents delivered by the Company at Closing
pursuant to Sections 2C or 2N;

            (ii) any and all Losses based upon, attributable to or resulting
from (A) the breach of any covenant or agreement on the part of the Company
under this Agreement or (B) the enforcement of this Agreement (including,
without limitation, this Section 12D); and

            (iii) any and all notices, actions, suits, proceedings, demands,
assessments, judgments, costs, penalties and expenses, including attorneys' and
other professionals, fees and disbursements (collectively, "EXPENSES") incident
to the foregoing;

PROVIDED, HOWEVER, that (x) the Company shall not have any liability for
indemnity hereunder until the aggregate amount of Losses and Expenses for which
the Purchaser Indemnified Parties would otherwise be entitled to receive
indemnification hereunder exceeds $350,000 (the "BASKET"), in which event the
Company shall be obligated to pay to the Purchaser Indemnified Parties the full
amount of such Losses and Expenses, inclusive of the Basket, and (y) the Company
shall not have any liability for indemnity hereunder in an aggregate amount in
excess of $35,000,000; provided, further, however, that notwithstanding clause
(x) above, the Basket shall not apply to restrict, reduce or limit any liability
of the Company for indemnity hereunder for any Losses and Expenses of the
Purchaser Indemnified Parties, based upon, attributable to or resulting from any
willful failures ("willful" to be defined as after having been given reasonable
notice and a 60 day period to cure such failure), to fully discharge any
covenant or agreement on the part of the Company under this Agreement which by
its terms are to be performed after the Closing Date.

      (c) Each of the Shareholders hereby severally agrees to indemnify and hold
harmless the Purchaser Indemnified Parties from and against:

                                       34
<PAGE>
            (i) subject to paragraph (a) of this Section 12D, any and all Losses
based upon, attributable to or resulting from any inaccuracy in or breach of any
representation or warranty by such Shareholder under Section 7 of this Agreement
or by such Shareholder in any of the documents delivered at Closing pursuant to
Section 2C or 2N of this Agreement; provided, however, that no Shareholder shall
be required to indemnify or hold harmless any Purchaser Indemnified Party under
paragraph (c) of this Section 12D for any inaccuracy or breach of representation
or warranty by any other Shareholder or the Company;

            (ii) any and all Losses based upon, attributable to or resulting
from the enforcement of this Agreement against such Shareholder (including,
without limitation, paragraph (c) of this Section 12D); and

            (iii) any and all Expenses incident to the foregoing;

PROVIDED, HOWEVER, that in no event shall the aggregate liability of any of the
Shareholders for indemnity under paragraph (c) of this Section 12D exceed the
product of (x) the aggregate number of shares of Common Stock sold by such
Shareholder hereunder multiplied by (y) $9.46.

      (d) The Purchaser hereby agrees to indemnify and hold harmless the Company
and its directors, officers, employees, Affiliates, agents, successors and
assigns and the Shareholders (collectively, the "Seller Indemnified Parties")
from and against:

            (i) subject to paragraph (a) of this Section 12D, any and all
"Losses" based upon, attributable to or resulting from any inaccuracy in or
breach of any representation or warranty on the part of the Purchaser under this
Agreement, the ROV Agreeement or in any of the documents delivered by the
Purchaser at Closing pursuant to Sections 3C or 3K;

            (ii) any and all Losses based upon, attributable to or resulting
from (A) the breach of any covenant or agreement on the part of the Purchaser
under this Agreement or the ROV Agreement or (B) the enforcement of this
Agreement (including, without limitation , this Section 12D) or the ROV
Agreement; and

            (iii) any and all "Expenses" incident to the foregoing.

PROVIDED, HOWEVER, that (x) the Purchaser shall not have any liability for
indemnity hereunder until the aggregate amount of Losses and Expenses for which
the Seller Indemnified Parties would otherwise be entitled to receive
indemnification hereunder exceeds the Basket, in which event the Purchaser shall
be obligated to pay to the Seller Indemnified Parties the full amount of such
Losses and Expenses inclusive of the Basket, and (y) the Seller shall not have
any liability for indemnity hereunder (A) to the Company or its directors,
officers, employees, Affiliates, agents, successors and assigns in an aggregate
amount in excess of $4,999,997.86 or (B) to any of the Shareholders in an
aggregate amount in excess of the product of (1) the aggregate number of shares
of Common Stock sold by such Shareholder hereunder multiplied by (2) $9.46;
provided, further, however, that notwithstanding clause (x) above, the Basket
shall not apply to restrict, reduce or limit any liability of the Purchaser for
indemnity hereunder for any Losses and Expenses of the Seller Indemnified
Parties, based upon, attributable to or resulting from any willful failures
("willful" to be defined as after having been given reasonable notice and a 60
day period to cure such failure), to fully discharge any covenant or agreement
on the part of the Purchaser under this Agreement which by its terms are to be
performed after the Closing Date.

                                       35
<PAGE>
      (e) Subject to the limits on Losses and Expenses contained in Section 12D
(b) , (c) and (d) above, the Company, the Shareholders and the Purchaser agree
that any indemnification payment made hereunder will be treated by the parties
on their respective Tax Returns as an adjustment to the aggregate consideration
for the shares of Common Stock of the Company acquired by the Purchaser. If,
notwithstanding such treatment by the parties, any such indemnification payment
is determined to be taxable to the indemnified party by any taxing authority,
the indemnifying party shall also indemnify the indemnified party for any Taxes
and Related Costs payable by the indemnified party by reason of the receipt of
such indemnification payment.

      (f) In the event that any Legal Proceedings shall be instituted or
asserted by any Person in respect of which payment may be sought under this
Section 12D, the indemnified party shall reasonably and promptly cause written
notice of the assertion of any Legal Proceeding of which it has knowledge which
is covered by the indemnities under this Section 12D to be forwarded to the
indemnifying party; provided, however, that the failure of the indemnified party
to give such reasonable and prompt notice shall not release, waive or otherwise
offset the indemnifying party's obligations hereunder with respect thereto
except to the extent that the indemnifying party can demonstrate actual loss and
prejudice as a result of such failure. The indemnifying party shall have the
right, at its sole option and expense, to be represented by counsel of its
choice, which must be reasonably satisfactory to the indemnified party which
consent shall not be unreasonably withheld, conditioned or delayed, and to
defend against, negotiate, settle or otherwise deal with any Legal Proceeding
which relates to any Losses or Expenses indemnified against hereunder; PROVIDED,
however, that (i) prior to assuming control of such defense, the indemnifying
party shall verify in writing to the indemnified party that the indemnifying
party will be fully responsible (with no reservation of any rights) for all
Liabilities and obligations relating to such claim for indemnification and that
it will provide full indemnification with respect thereto and (ii) no settlement
shall be made without the prior written consent of the indemnified party, which
consent shall not be unreasonably withheld, conditioned or delayed. If the
indemnifying party elects to defend against, negotiate, settle or otherwise deal
with any Legal Proceeding which relates to any Losses indemnified against
hereunder, it shall within thirty (30) days (or sooner, if the nature of the
Legal Proceeding so requires) notify the indemnified party of its intent to do
so. If the indemnifying party elects not to defend against, negotiate, settle or
otherwise deal with any Legal Proceeding which relates to any Losses and
Expenses indemnified against hereunder, fails to notify the indemnified party of
its election as herein provided or contests its obligation to indemnify the
indemnified party for such Losses and Expenses under this Agreement, the
indemnified party may defend against, negotiate, settle or otherwise deal with
such Legal Proceeding. If the indemnified party defends any Legal Proceeding,
then the indemnifying party shall reimburse the indemnified party for the
reasonable Expenses of defending such Legal Proceeding upon submission of
periodic bills. The indemnified party may not settle any Legal Proceeding
without the prior written consent of the indemnifying party, which consent shall
not be unreasonably withheld, conditioned or delayed. If the indemnifying party
shall assume the defense of any Legal Proceeding, the indemnified party may
participate, at its own expense, in the defense of such Legal Proceeding;
PROVIDED, HOWEVER, such indemnified party shall be entitled to participate in
any such defense with separate counsel (other than the Nixon, Hargrave, Devans &
Doyle, LLP law firm) at the expense of the Indemnifying Party if (i) so
requested by the indemnifying party to participate or (ii) in the reasonable
opinion of counsel to the indemnified party, a conflict or potential conflict
exists between the indemnified party and the indemnifying party that would make
such separate representation advisable. The parties hereto agree to cooperate
fully with each other in connection with the defense, negotiation or settlement
of any such Legal Proceeding.

      After any final judgment or award shall have been rendered by a court,
arbitration board or administrative agency of competent jurisdiction and the
expiration of the time in which to appeal therefrom, 

                                       36
<PAGE>
or a settlement shall have been consummated, or the indemnified party and the
indemnifying party shall have arrived at a mutually binding agreement with
respect to a Legal Proceeding hereunder, the indemnified party shall forward to
the indemnifying party notice of any sums due and owing by the indemnifying
party pursuant to this Agreement with respect to such matter and the
indemnifying party shall be required to pay all of the sums so due and owing to
the indemnified party by wire transfer of immediately available funds within
five business days after the date of such notice.

      12E. SUCCESSORS AND ASSIGNS. Except as otherwise expressly provided
herein, all covenants and agreements contained in this Agreement by or on behalf
of any of the parties hereto shall bind and inure to the benefit of the
respective successors and assigns of the parties hereto whether so expressed or
not. In addition, and whether or not any express assignment has been made, the
provisions of this Agreement which are for the Purchaser's benefit as a
purchaser or holder of Common Stock are also for the benefit of, and enforceable
by, any Purchaser Party, including any subsequent holder of such Common Stock.

      12F. SEVERABILITY. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable law, such provision shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

      12G. COUNTERPARTS. This Agreement may be executed simultaneously in two or
more counterparts, any one of which need not contain the signatures of more than
one party, and all such counterparts taken together shall constitute one and the
same Agreement.

      12H. TABLE OF CONTENTS AND SECTION HEADINGS; INTERPRETATION. The table of
contents and section headings of this Agreement are inserted for convenience
only, do not constitute a part of this Agreement and are to be given no effect
in the construction or interpretation of this Agreement. The use of the word
"including" in this Agreement shall be by way of example rather than by
limitation.

      12I. GOVERNING LAW; SUBMISSION TO JURISDICTION; CONSENT TO SERVICE OF
PROCESS. (a) Except as expressly provided in Section 12J, the internal law, and
not the conflict of laws principles, of the State of New York shall govern this
Agreement as well as the construction, validity and interpretation of this
Agreement and the exhibits and schedules hereto.

            (b) Solely to the extent permitted by Section 12J hereof, each of
the parties hereto hereby irrevocably submit for itself or himself and its or
his property to the non-exclusive jurisdiction of any federal or state court
located within the State of New York over any Dispute (as hereinafter defined)
and each party hereby irrevocably agrees that all claims in respect of such
Dispute or any action, suit or proceeding related thereto, solely to the extent
expressly permitted by Section 12J hereof, may be heard and determined in such
courts. The parties hereby irrevocably waive, to the fullest extent permitted by
applicable law, any objection which they may now or hereafter have to the laying
of venue of any Dispute brought in such court or any defense of inconvenient
forum for the maintenance of such Dispute, provided that relief sought in any
action, suit or proceeding relating thereto is of the nature expressly permitted
by Section 12J hereof to be sought in such court. Each of the parties hereto
agrees that an Award or a judgment in any such Dispute may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.

            (c) Each of the parties hereto hereby consents to process being
served by any party to this Agreement in any suit, action or proceeding of the
nature expressly permitted by Section 12J hereof by the delivery or mailing of a
copy thereof; in accordance with the provisions of Section 12K.

                                       37
<PAGE>
            (d) Nothing in this Section 12I shall affect the rights of the
parties to commence any action, suit or proceeding of the nature expressly
permitted by Section 12J hereof in any other forum or to serve process in any
such action, suit or proceeding in any other manner permitted by law.

      12J. ARBITRATION. (a) Any claim, dispute or other disagreement (each, a
"DISPUTE") between a Purchaser Indemnified Party, on the one hand, and the
Company or any of the Shareholders, on the other hand, arising out of or
relating to this Agreement or any of the transactions contemplated hereby shall
be finally settled by arbitration in accordance with the terms of this Section
12J; provided that any party shall in any event have the right to seek and
obtain equitable relief during the pendency of such Dispute pursuant to Section
12J(b) hereof. In the event of any Dispute, any party may serve written notice
of such Dispute on any other party and each party to such Dispute shall
undertake in good faith to resolve such Dispute. If the parties cannot agree to
resolve such Dispute within 15 days after such written notice, any party to such
Dispute may, by further written notice (the "ARBITRATION NOTICE") to the other
party, commence an arbitration proceeding by bringing the Dispute to an
arbitration panel selected as provided below. The Arbitration Notice shall be
filed simultaneously with the International Chamber of Commerce in New York, New
York, and shall contain a description of the amount in controversy, the nature
of the Dispute and the paragraph(s) of this Agreement to which such Dispute
relates. Disputes shall be decided by an arbitration panel comprised of three
arbitrators (each of whom shall be a practicing lawyer knowledgeable and
experienced in matters of corporate, mergers and acquisitions and securities
law), one arbitrator to be selected by the Purchaser Indemnified Party, a second
arbitrator to be selected by the Company, and the third arbitrator (the
"INDEPENDENT ARBITRATOR"), who will be the Chairman of the arbitration panel, to
be appointed by the first two arbitrators. In the event the first two
arbitrators fail to agree on the appointment of the Independent Arbitrator
within 15 days, the Independent Arbitrator shall be appointed by the
International Chamber of Commerce in New York, New York. In the event that any
arbitrator shall resign, be unable or otherwise fail to perform his or her
duties, each party shall immediately notify the other parties of such
resignation, inability or failure, and a replacement shall immediately be
selected by the party who selected such arbitrator in the first instance, or, if
the arbitrator to be replaced is the Independent Arbitrator, then the parties
shall attempt in good faith to appoint a mutually agreeable replacement
Independent Arbitrator. If the parties fail to agree on such replacement within
15 days, either party may request that the International Chamber of Commerce in
New York, New York appoint such replacement Independent Arbitrator. The
arbitration panel shall conduct the arbitration in accordance with the Rules of
Arbitration of the International Chamber of Commerce then in effect, except to
the extent such rules are inconsistent with the provisions of this Section 12J.
The parties shall prepare in writing a statement of their positions, together
with counterclaims, with supporting facts, data, and affidavits, if any, for the
arbitration panel and shall submit such statement to the arbitration panel
within 15 days after it is selected, but, in any event, within 60 days after
service of the Arbitration Notice. The arbitration panel shall give all parties
the opportunity to make an oral presentation to the arbitration panel in the
presence of the other party if either party so requests. The parties shall have,
for a period of 180 days after service of the Arbitration Notice (the "DISCOVERY
PERIOD"), all rights of discovery provided by the New York Civil Practice Law
and Rules then obtaining, except, unless otherwise agreed, that all responses to
discovery requests shall be served within 10 days of such discovery request, and
no discovery request may be served after the date 10 days before the termination
of the Discovery Period. Subject to the proviso in the first sentence of this
Section 12J(a) and to Section 12J(b) hereof, the arbitration panel shall assume
exclusive jurisdiction over the Dispute, may order interim equitable relief
(which shall be specifically enforceable as if it were a final Award, as
hereinafter defined), and shall be required to make a final binding
determination (the "AWARD"). The Award shall not be subject to appeal to or
review by any court or administrative body except as set forth in Section 10(a)
of the Federal Arbitration Act, codified as 9 U.S.C.A. ss.10(a) (West Supp.
1997). The Award shall determine (i) whether each party's obligations under this
Agreement were met and 

                                       38
<PAGE>
(ii) what damages or remedies (which may include final equitable relief) are due
to the Purchaser Indemnified Party, on the one hand, or the Company or
Shareholder on the other hand, under the terms of this Agreement. The agreement
to arbitrate contained in this Section 12J shall be specifically enforceable
under the prevailing arbitration law, and shall survive termination of this
Agreement. Judgment upon the Award rendered by the arbitration panel may be
entered in accordance with applicable law in any court having jurisdiction
therefor. Each party shall bear its own costs and expenses for arbitration,
subject to reimbursement as determined by the arbitration panel in the Award.
Arbitration shall, unless the parties otherwise agree in writing, take place in
New York, New York.

            (b) Nothing contained in this Section 12J shall preclude, or be
deemed, construed or interpreted to preclude, any party from seeking interim
equitable relief from a court of competent jurisdiction against the other party,
where circumstances so require, except that no party shall be entitled to seek a
stay of any arbitration proceeding brought hereunder. The parties agree that,
upon the application of any of the parties, and whether or not an arbitration
proceeding has yet been initiated pursuant to this Section 12J, all courts
having jurisdiction are hereby authorized to (i) issue and enforce in any lawful
manner such temporary restraining orders, preliminary injunctions and other
interim measures of relief as may be necessary to prevent harm to a party's
interests or as otherwise may be appropriate pending the conclusion of
arbitration proceedings pursuant to this Section 12J, and/or (ii) enter into and
enforce in any lawful manner such judgments for permanent equitable relief as
may be necessary to prevent harm to a party's interests or as otherwise may be
appropriate following the issuance of the Award.

            12K. NOTICES. All notices, demands or other communications to be

2.      THE JOINT VENTURE ENTITY.

    (a) FORMATION. As soon as practicable after the execution of this Agreement
but in any event no later than June 30, 1997, Cal Dive and CSO shall cause the
Joint Venture Entity to be formed as a Delaware limited liability company under
a name mutually agreed to by the parties and shall cause the Formation Documents
to be duly executed and filed as necessary. The Formation Documents shall be
governed by Delaware Law without regard to its conflicts of laws principles. The
provisions of this Agreement shall be incorporated into the Formation Documents
to the extent necessary to make such provisions enforceable. To the extent that
it is necessary to form the Joint Venture Entity as a partnership for state or
foreign income tax purposes, the parties agree that the Joint Venture Entity
will be formed as a Delaware limited partnership in which each of the parties
will be limited partners and a newly-formed Delaware limited liability company
will be the general partner owning a 1% interest in the Joint Venture Entity. In
such event, the governance provisions in this Agreement shall be incorporated
into the organizational documents of the general partner and shall control the
general partner's management of the Joint Venture Entity.

    (b) CAPITAL CONTRIBUTIONS. Cal Dive and CSO shall each contribute to the
Joint Venture Entity such capital and/or property as shall be mutually agreed by
the parties and described in the Formation Documents, and in consideration
therefor the parties shall receive the respective Percentage Interests set forth
on Schedule B. The value of the capital and/or property contributed to the Joint
Venture Entity by each of Cal Dive and CSO shall have a fair market value (net
of any liabilities to which such capital or property is subject which are
assumed by the Joint Venture Entity) equal to their respective Percentage
Interests multiplied by the fair market value of all capital and/or property
contributed to the Joint Venture Entity by Cal Dive and CSO collectively. Except
as mutually agreed by the parties and disclosed in the Formation Documents, Cal
Dive and CSO shall have good and marketable title to the capital and/or property
contributed by each of them to the Joint Venture Entity, and such capital and/or
property shall be contributed to the Joint Venture Entity free and clear of all
Liens other than, in the case of Cal Dive, Liens in favor of Fleet Capital
Corporation ("Fleet") in connection with that certain Loan and Amended and
Restated Security Loan Agreement dated as of May 23, 1995 between Cal Dive and
Fleet, as the same may hereafter be amended, modified or supplemented from time
to time. Cal Dive and CSO may make future contributions to the Joint Venture
Entity to the extent agreed in writing between the parties. In the event that
the Board determines that additional capital is necessary to operate the Joint
Venture Entity and one party contributes additional capital but the other does
not, the Percentage Interests of the parties shall be adjusted proportionately
based on the additional amount contributed by the party and the agreed value of
the capital and property contributed to the Joint Venture Entity prior to such
additional contribution.

    (c) GOVERNANCE. The Joint Venture Entity shall be governed by the Board. The
Board shall initially consist of two members, with one member being appointed by
each of Cal Dive and CSO. The Board may increase or decrease its size at any
time; provided, the Board shall at all times consist of an even number of
members and each of Cal Dive and CSO shall at all times be entitled to appoint
an equal number of members to the Board. The Persons appointed as members of the
Board shall be officers or employees of Cal Dive, CSO or their Affiliates. A
majority of the Board shall constitute a quorum for the conduct of business and
the affirmative vote of a majority of the Board members present at a meeting at
which a quorum is present shall be required to take action by the Board except
as provided below:

    (i) A majority of the members of the Board appointed by Cal Dive or CSO
shall have the power to authorize and take such actions as are necessary to
cause the Joint Venture Entity to enforce any rights it has against CSO or Cal
Dive, respectively; and

    (ii) Contracts between the Joint Venture Entity and a Person relating to Cal
Dive Services and contracts between the Joint Venture Entity and a Person
relating to CSO Services, in each case after complying with paragraph 3(c) of
this Agreement, may be authorized by a majority of the members of the Board
appointed by CSO or Cal Dive, respectively.

    (d) TAX TREATMENT. Cal Dive and CSO agree to take all actions, including but
not limited to making such elections and including appropriate provisions in the
Formation Documents, which are necessary to cause the Joint Venture Entity to be
taxed as a partnership for federal, state (where possible) and foreign income
tax purposes.

    (e) DISTRIBUTION. The Formation Documents shall require that, unless
otherwise unanimously agreed by the Members, the Joint Venture Entity must make
distributions at such times and in such amounts as shall permit the Members to
satisfy their respective tax obligations resulting from income or gain of the
Joint Venture Entity allocated to them. The Joint Venture Entity shall make such
other distributions as shall be determined from time to time by the Board. All
distributions shall be allocated between or among the Members based on the
respective Percentage Interests of the Members.

    (f) FISCAL YEAR. Cal Dive and CSO agree to take all actions necessary to
cause the fiscal year end of the Joint Venture Entity to be December 31st of
each year.

    (g) DURATION. The duration of the Joint Venture Entity shall be perpetual or
for such limited period as the parties may mutually agree; provided, that upon
the expiration or termination of this Agreement pursuant to Section 5 hereof and
after such period of time as may be required for the Joint Venture Entity to
perform or complete contracts entered into or undertaken prior to the expiration
or termination of this Agreement, Cal Dive and CSO each agree to execute and
file or cause to be filed such documents as are necessary to dissolve the Joint
Venture Entity and its general partner, if applicable.

    (h) DISSOLUTION. Upon the dissolution of the Joint Venture Entity its assets
shall be liquidated and distributed to the Members as provided in the Formation
Documents. The Formation Documents shall provide for the distribution in-kind to
Cal Dive or CSO, upon their request and provided sufficient assets are
available, of any assets contributed to the Joint Venture Entity by Cal Dive or
CSO, respectively, as described in the Formation Documents. Assets distributed
in-kind shall be treated as a distribution equal to the fair market value of the
asset on the date of distribution as determined by an independent appraiser
selected the Board having expertise in valuing the type of asset being
distributed (an "Independent Appraiser"). If there are not sufficient assets of
the Joint Venture Entity to distribute assets in-kind as provided by this
paragraph, Cal Dive and CSO 
<PAGE>
                                     - 5 -

shall each have the option to purchase any assets contributed by them to the
Joint Venture Entity pursuant to this Agreement for the fair market value of
such assets as of the date of purchase as determined by an Independent
Appraiser.

    (i) TRANSFER RESTRICTIONS. The parties agree that the purpose for using the
Joint Venture Entity to carry out the activities contemplated by this Agreement
is to limit the liability of the parties in connection with such activities and
to provide the parties with favorable tax treatment for income resulting from
such activities. Because of the personal nature of the Services to be provided
to the Joint Venture Entity by the parties and the importance to the Joint
Venture Entity of its relationship with each of the parties, the parties agree
to cause the Formation Documents to contain prohibitions on transfer of
interests in the Joint Venture Entity and the general partner, if applicable
(collectively, the "Interests"), except in accordance with the following
provisions: (i) an option provision pursuant to which the Joint Venture Entity
and the non-transferring Member have an option to purchase any Interests for the
book value of such Interests upon the Bankruptcy of the holder of such Interests
or the occurrence of any event which could result in an involuntary Transfer of
such Interests; (ii) a provision granting Coflexip, a French corporation which
is an Affiliate of CSO ("Coflexip"), and/or its Affiliates the right to purchase
Cal Dive's Interests under certain circumstances as provided in Section 10.2 of
that certain Shareholders Agreement dated as of the date hereof among Cal Dive,
Coflexip and the other shareholders of Cal Dive; or (iii) a provision permitting
a party to Transfer its Interests after complying with the following procedures:
(A) a party proposing to Transfer its Interests (the "Transferring Party") must
give the other party (the "Non-Transferring Party") written notice of such
intention and the price at which it proposes to Transfer its Interests and such
other material terms regarding such Transfer as may then be in the possession of
the Transferring Party; (B) the parties will negotiate in good faith for a
period of up to one year to reach agreement on the terms and conditions of the
proposed Transfer (including, without limitation, if necessary, the survival
following the Transfer of certain obligations of the Transferring Party under
this Agreement) while using their reasonable best efforts during such
negotiations to maintain the value of the Joint Venture Entity; (C) if the
parties cannot reach agreement within such one-year period, either party may,
within ten (10) days following the end of such period, offer to sell such
party's Interests to the other party, which offer shall be in writing and shall
specifically reference this clause (iii) of this paragraph (2)(i); (D) if such
offer is not accepted by the other party within ten (10) days, the offering
party shall have the right, exercisable in writing for a period of ten (10)
days, to purchase the other party's Interests at the price for which it offered
to sell its Interests to the other party (adjusted to take into account the
different Percentage Interests of the respective parties); (E) if an offer to
sell is accepted or the offering party exercises its right to purchase pursuant
to this paragraph, the transaction shall be completed within thirty (30) days of
such acceptance or exercise; (F) if no offer to sell is accepted and no party
exercises its right to buy, the Non-Transferring Party shall have the right, for
a period of ten (10) days following the last applicable time period above (i.e.,
ten (10) days after the end of the one-year period if no offer is made or thirty
(30) days after the end of the one-year period if an offer is made), to
terminate this Agreement pursuant to paragraph 5(b); and (G) if this Agreement
is not terminated by the Non-Transferring Party pursuant to clause (iii)(F)
above, the Transferring Party may Transfer its Interests at a price no less than
the price specified in the notice given pursuant to clause (iii)(A) above. The
Formation Documents shall require that a party's interest in the general partner
of the Joint Venture Entity, if applicable, be Transferred simultaneously with a
party's interest in the Joint Venture. Upon a Transfer by a party of its
Interests, such party's rights and obligations under this Agreement and the
Formation Documents shall cease except for the obligations of such party under
the paragraphs referenced in paragraph 5(c) of this Agreement. The Person to
whom a party assigns its Interests shall have no rights (i) under this Agreement
except to the extent that such rights are assigned to such assignee in
compliance with paragraph 6(f) hereof, or (ii) under the Formation Documents,
other than to share in profits and losses, receive distributions and receive
allocations of income, gain, loss, deduction or credit to the extent assigned,
unless such Person is admitted as a Member with the prior written consent of the
other Member or Members of the Joint Venture Entity.

      (j) DEADLOCK. If the Board has been unable to act for a period of at least
six (6) months as a result of a dispute concerning the management of the Joint
Venture Entity which has not been resolved pursuant to subparagraph 4(j)(i)
hereof, either party may offer to sell such party's Interests to the other
party. Any such offer shall be in writing and shall specifically reference this
paragraph 2(j). If such offer is not accepted by the other party within fifteen
(15) days, the offering party shall have the right, exercisable in writing for a
period of fifteen (15) days, to purchase the other party's Interests at the
price for which it offered to sell its Interests to the other party (adjusted to
take into account the different Percentage Interests of the respective parties).
If an offer to sell is accepted or the offering party exercises its right to
purchase pursuant to this paragraph, the transaction shall be completed within
thirty (30) days of such acceptance or exercise. Upon a Transfer by a party of
its Interests pursuant to this paragraph 2(j), such party's rights and
obligations under this Agreement and the Formation Documents shall cease except
for the obligations of such party under the paragraphs referenced in paragraph
5(c) of this Agreement.

3.      OPERATION OF THE JOINT VENTURE ENTITY.

    (a) EPIC PROJECTS. The primary purpose of the Joint Venture Entity is to
procure contracts to undertake EPIC Projects in the Territory. Unless otherwise
negotiated and mutually agreed on a projectby-project basis, the Joint Venture
Entity shall bid as the prime contractor for such EPIC Projects and, subject to
paragraph 3(c) below, Cal Dive and CSO shall subcontract with the Joint Venture
Entity to provide, respectively, the Cal Dive Services and CSO Services required
in connection with such EPIC Projects. With respect to each EPIC Project for
which the Joint Venture Entity desires to compete, the Joint Venture Entity
shall request a bid from Cal Dive for the performance of the Cal Dive Services
required by such EPIC Project and shall request a bid from CSO for the
performance of the CSO Services required by such EPIC Project. Cal Dive and CSO
shall prepare and submit to the Joint Venture Entity bids for the Services based
on the amounts regularly charged by them for comparable Services which they
provide to their other customers, taking into account the geographic area in
which the Services are to be performed, the scope of the Services to be
performed and such other relevant pricing factors. Each party shall, upon the
written request of the Joint Venture Entity, provide the Joint Venture Entity
with information documenting that the amounts included in the bids submitted to
the Joint Venture Entity are prepared on the basis set forth above. The Joint
Venture Entity may accept such bids or may contract with other Persons pursuant
to paragraph 3(c) below.

    (b) OTHER PROJECTS. When commercially practicable, the Joint Venture Entity
may decide from time to time to seek to enter into contracts to provide Services
or engage in other business activities in geographic areas outside the Territory
or may seek to enter into contracts for projects within the Territory which are
not EPIC Projects. With respect to such projects, Cal Dive shall have the
option, but shall not be obligated, to provide the Cal Dive Services required by
such projects and CSO shall have the option, but shall not be obligated, to
provide the CSO Services required by such projects. The parties contemplate that
subcontracts between the Joint Venture Entity and the parties will be entered
into in the same manner as provided in paragraph 3(a) above except that the
parties are not required to bid for such subcontracts. The Board shall, no less
frequently than once every six (6) months, consider opportunities presented by
projects outside the Territory having a scope comparable to EPIC Projects and
shall solicit input from Cal Dive and CSO regarding any such opportunities. The
Joint Venture Entity shall not enter into any projects outside the Territory
unless specifically approved by the Board.

    (c) CONTRACTING WITH OTHERS. The Joint Venture Entity shall be free to
contract with Persons other than Cal Dive and CSO for the performance of
Services in connection with EPIC Projects or other projects if either Cal Dive
or CSO, as applicable, is not willing to provide the Services on terms and
conditions which are as favorable to the Joint Venture Entity as those offered
by such other Persons. Prior to contracting with a 
<PAGE>
                                     - 7 -

Person other than Cal Dive or CSO for the performance of Services, the Joint
Venture Entity shall provide Cal Dive or CSO, as the case may be, with the terms
and conditions which the Joint Venture Entity is proposing to accept from a
third Person (the "Proposed Terms"). The Proposed Terms shall relate only to the
Services or the Services shall be separately valued in the Proposed Terms. Cal
Dive or CSO shall have the option of performing the Services on the same terms
and conditions as the Proposed Terms or upon such other arm's-length terms and
conditions as may be mutually agreed to in writing by the Joint Venture Entity
and Cal Dive or CSO. If Cal Dive or CSO does not exercise its right to perform
the Services in writing within ten (10) days after receiving the Proposed Terms
from the Joint Venture Entity, the Joint Venture Entity shall be free to obtain
the Services from another Person on terms and conditions which are no more
favorable to the Person providing such Services than the Proposed Terms.

    (d) INTERNAL CONTRACTING. Notwithstanding paragraph 3(c), the Joint Venture
Entity shall not contract with CSO to perform Cal Dive Services and shall not
contract with Cal Dive to perform CSO Services. Notwithstanding any provision of
this Agreement, the Joint Venture Entity shall have no obligation to contract
with Cal Dive or CSO for any Services which it is capable of performing itself.
Notwithstanding anything in this Agreement to the contrary, all transactions
between the Joint Venture Entity and either party or an Affiliate of either
party shall be no less favorable to the Joint Venture Entity than would be the
case with unrelated entities in arm's-length transactions. Transactions between
the Joint Venture Entity and a party or an Affiliate of a party shall be
presumed to be in compliance with the foregoing if such transaction or contract
was approved by the Board in accordance with paragraph 2(c) after disclosure of
all material facts as to the interest of the party or Affiliate in such
transaction.

    (e) SERVICES AGREEMENTS. Each of Cal Dive and CSO shall enter into a service
agreement with the Joint Venture Entity to provide management, administrative,
support and other services to the Joint Venture Entity, in each case covering
such services and for the compensation as the parties shall agree. The parties
may provide the Joint Venture Entity with additional services at the Joint
Venture Entity's request on such terms and conditions as a third party would be
willing to provide such services to the Joint Venture Entity.

    (f) TERMS OF CONTRACTS. The subcontracts between each of Cal Dive and CSO
and the Joint Venture Entity which relate to the performance of Services by Cal
Dive or CSO for the Joint Venture Entity shall be governed by the terms and
conditions of the prime contract between the Joint Venture Entity and the
customer of the Joint Venture Entity (including the terms regarding
indemnification and governing law); provided, that if Cal Dive or CSO contracts
with the Joint Venture Entity pursuant to paragraph 3(c) hereof, Cal Dive or
CSO, as the case may be, may elect to have the subcontract governed by the terms
and conditions of the Proposed Terms to the extent that they differ from the
terms and conditions of the prime contract.

with a reasonably satisfactory insurance company or companies, insurance

4.     COVENANTS OF CAL DIVE AND CSO.

    (a) RESTRICTION ON THE PERFORMANCE OF SERVICES. Each of Cal Dive and CSO
acknowledges that the following restrictions are essential to permit the Joint
Venture Entity to function as intended by the parties and to prevent the parties
from usurping opportunities intended to be pursued by the Joint Venture Entity.
During the Restricted Period, each of Cal Dive and CSO agrees that it will not
(i) perform Services within the 
<PAGE>
                                     - 8 -

Territory or contract to perform Services within the Territory, in each case in
connection with any EPIC Project, (ii) permit any of its Affiliates or Persons
in which it owns a Controlling Interest to perform such Services within the
territory in connection with any EPIC Project, or (iii) except for such
relationships as they exist as of the date hereof, become a shareholder,
partner, member, owner, principal, consultant or agent of any Person engaged in
performing any Services that are already performed by the other party within the
Territory (whether or not in connection with an EPIC Project); provided, that
(A) Cal Dive, its Affiliates and Persons in which it owns a Controlling Interest
are permitted to perform Cal Dive Services for the Joint Venture Entity in
connection with EPIC Projects, (B) CSO, its Affiliates and Persons in which it
owns a Controlling Interest are permitted to perform CSO Services for the Joint
Venture Entity in connection with EPIC Projects, (C) Cal Dive and CSO may
complete the performance of any Services within the Territory which they are
obligated to perform under contracts existing prior to the Restricted Period,
and (D) Cal Dive and CSO will not be prohibited from bidding for and performing
services within the Territory under subcontracting arrangements in connection
with any EPIC Project where the Joint Venture Entity, despite the reasonable
best efforts of the Joint Venture Entity and the parties, was unsuccessful in
obtaining a contract for such EPIC Project, did not have the opportunity to bid
for such EPIC Project, elected not to bid for such EPIC Project, or under such
other circumstances as the parties may agree, provided that in each such case
the party seeking to bid for such subcontracting arrangements first notifies the
other party of its intention to do so and such other party consents in writing
thereto within fifteen (15) days after receipt of such notice, which consent
shall not be unreasonably withheld, conditioned or delayed. The foregoing
restriction is specifically not intended to restrict the performance, or
contracting for the performance, of Services outside the Territory or to
restrict Cal Dive or CSO from performing or contracting to perform Services
within the Territory other than in connection with EPIC Projects.

    (b) RESTRICTION ON ACTIVITIES IN THE NORTH SEA AND BRAZIL. Cal Dive agrees
that if it becomes aware of any activities involving Services in the North Sea
or Brazil that it will present such opportunities to and discuss such
opportunities with CSO prior to taking any actions in pursuit of such
opportunities.

    (c) COOPERATION. When Cal Dive is engaged in any project where it is
required to provide CSO Services, Cal Dive shall offer CSO the opportunity to
provide such CSO Services in connection with such project. When CSO is engaged
in any project where it is required to provide Cal Dive Services, CSO shall
offer Cal Dive the opportunity to provide such Cal Dive Services in connection
with such project. When a party (the "Offeror") is required to provide the other
party (the "Offeree") with the opportunity to provide Services pursuant to this
paragraph 4(c). The Offeree shall provide the Services to the Offeror at
arm's-length rates determined as follows: the Offeror shall provide the Offeree
with the most favorable (to the Offeror) terms and conditions which the Offeror
is able to obtain from another provider (which terms and conditions relate only
to the Services to be offered to the Offeree or which separately value such
Services), and the Offeree shall have the option of providing the Services on
the same terms and conditions as those forwarded to the Offeree with the offer
or upon such other arm's-length terms and conditions as may be mutually agreed
to in writing by the Offeror and the Offeree. If the Offeree does not exercise
its right to provide the Services in writing within ten (10) days after
receiving the offer, the Offeror shall be free to obtain the Services from
another Person on terms and conditions which are no more favorable to the Person
providing such Services than the terms and conditions offered to the Offeree.

    (D)    TECHNOLOGY.

    (i) Technology owned by a party prior to this Agreement or developed by a
party in connection with this Agreement shall remain the sole and exclusive
property of such party unless sold or otherwise transferred for consideration to
the Joint Venture Entity. Without limiting the generality of the foregoing, any
Technology developed by a party in connection with providing Services to the
Joint Venture Entity shall be the sole and exclusive property of such party, and
the Joint Venture Entity shall have no interest therein.
<PAGE>
                                     - 9 -

    (ii) Technology developed independently by the Joint Venture Entity shall be
the sole and exclusive property of the Joint Venture Entity and neither party
shall have any interest therein.

    (iii) Technology developed in connection with this Agreement jointly by the
parties or by one or both parties and the Joint Venture shall, to the extent
possible, be assigned to the party making the most substantial contribution to
the development of such Technology; provided, however, the party to whom such
Technology is assigned shall grant a perpetual, royalty-free, non-exclusive
license to use such Technology to the Joint Venture Entity if it independently
made a material contribution to the development of the Technology and to the
other party if it made such a contribution. The parties and the Joint Venture
Entity shall make such assignments and execute and deliver such other documents
as. shall be necessary to implement the provisions of this subparagraph.

    (iv) This paragraph 4(d) shall be subject to the terms of any License
Agreement or any other contract between the Joint Venture Entity and either
party or between the parties, and in the event of any conflict between the terms
of such License Agreement or other contract and this Agreement, the terms of
such License Agreement or other contract shall control.

    (v) Upon the request by either party, the other party shall execute and
deliver, and shall cooperate to cause the Joint Venture Entity to execute and
deliver, a secrecy agreement restricting the release of Technology between
themselves and/or third parties in connection with the business activities
contemplated by this Agreement.

    (e) CONFIDENTIALITY. Except as otherwise agreed by the parties in writing,
the parties agree that, at all times during the term of this Agreement and for a
five-year period following termination or expiration hereof, either party
receiving information (the "Receiving Party") from the other party shall keep
completely confidential, shall not publish or otherwise disclose and shall not
use, directly or indirectly, for any purpose any information furnished to it by
the other party (the "Disclosing Party") pursuant to this Agreement or otherwise
relating to any transaction contemplated hereby, except to the extent that the
Receiving Party can establish by competent proof that such information:

    (i) was already known to the Receiving Party, other than under an obligation
of confidentiality, at the time of disclosure by the Disclosing Party;

    (ii) was part of the public domain at the time of its disclosure by the
Disclosing Party;

    (iii) became part of the public domain after its disclosure by the
Disclosing Party, other than through any act or omission of the Receiving Party
in breach of this Agreement;

    (iv) was disclosed to the Receiving Party by a third party who had no
obligation not to disclose such information to others; or

    (v) has been disclosed by the Disclosing Party to any third party without an
obligation not to disclose such information to others.

The parties agree to take such actions and execute such documents as are
necessary to cause the Joint Venture Entity to comply with this provision as a
Receiving Party. Each Receiving Party may disclose the Disclosing Party's
information to the extent that such disclosure is reasonably necessary in
pursuing or defending litigation, or complying with applicable law or
governmental or stock exchange (including The Nasdaq Stock Market)
<PAGE>
                                     - 10 -

regulations; provided, however, that, if a Receiving Party intends to make any
such disclosure, it shall (i) give reasonable advance written notice to the
Disclosing Party of such intention so that the Disclosing Party may seek an
appropriate protective order, and (ii) not disclose any information pending
conclusion of any legal proceedings regarding such protective order. In the
event that disclosure is required after the conclusion of any proceedings, the
Receiving Party shall disclose only such Confidential Information as is
specifically required by the terms of such law, order, regulation or requirement
and shall use its best efforts to obtain from the party to whom the information
is disclosed written assurance that confidential treatment will be accorded to
such information. Furthermore, nothing in this paragraph shall be construed to
preclude either party or the Joint Venture Entity from disclosing such
information to third parties as may be necessary in connection with the
transactions contemplated by this Agreement; provided, however, that the
Receiving Party or the Joint Venture Entity shall in each case obtain from the
proposed third-party recipient a written confidentiality undertaking containing
confidentiality obligations no less onerous than those set forth in this
paragraph. The parties shall, when appropriate, cause their respective officers,
directors, employees, agents and other personnel to execute and deliver
confidentiality agreements to ensure compliance with the confidentiality
obligations contained herein.

    (f) NON-SOLICITATION. During the term of this Agreement and for a three-year
period following termination or expiration hereof, neither party nor the Joint
Venture Entity shall, directly or indirectly, without the written consent of the
applicable party: (i) hire or solicit any employee of a party or encourage any
such employee to leave such employment, or (ii) solicit, induce or influence any
customer, supplier, lender, lessor or any other person or entity which has a
business relationship with a party to discontinue or reduce the extent of such
relationship with such party.

    (g) INDEPENDENT CONTRACTOR. Each party shall be responsible for its
obligations under this Agreement and under any resulting contract to which it is
a party as contemplated by this Agreement, but shall not otherwise have any
obligation or liability with respect to unrelated business activities of the
other party, it being agreed that each party is an independent contractor and
that neither party, its agents, or employees are, or shall be, either actual or
constructive servants, agents or employees of the other party. This Agreement
shall not be deemed to create a partnership between Cal Dive and CSO.

    (h) PRESS RELEASES. Neither party nor their Affiliates shall make publicly
available any press release, promotional material or similar public statement
naming or otherwise identifying the other party or any of its Affiliates without
such other party's prior consent, which consent will not be unreasonably
withheld, conditioned or delayed. Each party and any of their respective
Affiliates shall provide the other party, as early as reasonably practicable,
drafts of all press releases that include references to such other party or any
of its Affiliates, and shall consider and use reasonable efforts to incorporate
into all such press releases any comments provided by such other party in a
reasonably timely manner. The parties agree to take such actions as are
necessary to cause the Joint Venture Entity to comply with this paragraph.

    (i) FORCE MAJEURE. THE failure or delay of either party hereto to perform
any obligation under this Agreement solely by reason of acts of God, acts of
government (except as otherwise enumerated herein), riots, wars, embargoes,
strikes, lockouts, accidents in transportation, port congestion or other causes
beyond its control ("FORCE MAJEURE") shall not be deemed to be a breach of this
Agreement; provided, however, that the Party so prevented from complying
herewith shall have used reasonable diligence to avoid such event of FORCE
MAJEURE and mitigate its effects, and shall continue to take all actions within
its power to comply as fully as possible with the terms of this Agreement.
Except where the nature of the event shall prevent it from doing so, the party
suffering such FORCE MAJEURE shall notify the other party in writing within
fourteen (14) days after the occurrence of such event of FORCE MAJEURE and shall
in every instance, to the extent reasonable and lawful under the circumstances,
use its best efforts to remove or remedy such cause with all reasonable
dispatch.
<PAGE>
                                     - 11 -

    In the event of any conflict between the terms of this paragraph 4(i) and
the terms of any "force majeure" provision contained in any contract to which
the Joint Venture Entity is a party, the terms of the "force majeure" provision
contained in such other contract shall control.

        (j)   DISPUTE RESOLUTION.

    (i) The parties shall attempt in good faith to resolve any Dispute as
defined in paragraph 6(k) or any disagreement concerning the management of the
Joint Venture Entity (a "Management Disagreement") promptly by negotiation
between executives who have authority to settle the controversy and who are at a
higher level of management than the persons with direct responsibility for
administration of this Agreement. Any party may give the other party written
notice of any Dispute or Management Disagreement not resolved in the normal
course of business (the "Initial Notice"), which notice shall include (A) a
statement of such party's position and a summary of arguments supporting that
position; and (B) the name and title of the executive who will represent that
party and of any other person who will accompany the executive to a meeting to
discuss the matter. Within five (5) business days after delivery of the Initial
Notice, the receiving party shall provide the other party with a notice
containing comparable information. Within ten (10) days after delivery of the
Initial Notice, the executives of both parties shall meet at a mutually
acceptable time and place, and shall meet thereafter as often as they reasonably
deem necessary, to attempt to resolve the Dispute or Management Disagreement.
All reasonable requests for information made by one party to the other party
will be honored.

    (ii) If a Dispute (but not a Management Disagreement) is not resolved within
thirty (30) days after the date of the Initial Notice, the executives will
select an independent Person (the "Mediator") who is not a present or former
officer, director, employee or agent of either party to act as a mediator to
resolve such Dispute. Within five (5) business days after the Mediator is
appointed, the executives and the Mediator shall meet at a mutually acceptable
time and place to discuss the Dispute, and both parties shall promptly provide
the Mediator with such information as the Mediator shall reasonably request. The
Mediator shall investigate the Dispute and submit a proposed solution to the
executives within thirty (30) days after being appointed as the Mediator. If
such proposed solution is not acceptable to either party, such party may
commence arbitration proceedings pursuant to paragraph 6(k) hereof.

    (iii) All discussions, negotiations and information provided pursuant to
this paragraph 4(j) are confidential and shall be treated as compromise and
settlement negotiations for purposes of the Federal Rules of Evidence and State
Rules of Evidence.

    (k) FURTHER ASSURANCES. Cal Dive and CSO each agree to execute and deliver
such other documents or agreements and take such other actions as may be
necessary or desirable for the implementation of this Agreement and the
consummation of the transactions contemplated hereby. Without limiting the
generality of the foregoing, each of Cal Dive and CSO agree to use commercially
reasonable efforts to promote the business of the Joint Venture Entity in
connection with EPIC Projects within the territory.

    (1) WAIVER OF CONFLICTS. Each of the parties hereto, for itself, its
Affiliates and on behalf of the Joint Venture Entity, hereby waive any claim or
cause of action against the other party or its Affiliates and any member of the
Board appointed by the other party as a result of any breach of any duty to the
Joint Venture Entity by any such Person as a result of a conflict of interest
between the Joint Venture Entity and the party or its Affiliates other than the
breach of a duty expressly imposed pursuant to this Agreement or another
agreement between such party and the Joint Venture Entity. Except as provided in
paragraph 4(a), neither party nor their Affiliates shall be prohibited from
competing with the Joint Venture Entity in any respect or be obligated to
reserve any business opportunity for the Joint Venture Entity. The Formation
Documents shall contain provisions exculpating Board 
<PAGE>
                                     - 12 -

members from liability for any breach of a fiduciary duty other than for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law or for any transaction from which such member derived an
improper personal benefit.

5.     TERM; TERMINATION; SURVIVAL; DEFAULT.

    (a) TERM; EXTENSION. The initial term of this Agreement shall be for a
period of ten years from the date of the formation of the Joint Venture Entity.

year periods following the initial term or any subsequent extended term by
giving notice to the other party prior to the end of the initial or extended
term of its intention to extend the term of the Agreement for an additional five

months after receiving notice of the occurrence of such event from the other
party;

    (iv) by a Non-Transferring Party pursuant to clause (iii)(F) of paragraph

paragraph 4(i), for any reason to meet any of its obligations under this
Agreement or in connection with any contract to provide Services entered into
with the Joint Venture Entity or the non-defaulting party, the other party may
give written notice to the defaulting party of such default.

      (i) Subject to the resolution thereof pursuant to subparagraph 4(j)(i) if
such default results in a dispute hereunder, if the defaulting party does not
cure any such default within sixty (60) days following the giving of notice as
provided in paragraph 5(d), then, until such default is cured or a good faith
effort to cure such fault has commenced, the other party shall have the
following rights:
<PAGE>
                                     - 13 -

    (A) to cure any such default without prejudice to its rights against the
defaulting party for full indemnification therefrom (including interest at a

during the duration of such default as reported in the Wall Street Journal); and

reasonably necessary to cure the default as promptly as practicable, the
non-defaulting party shall have the right to terminate this Agreement, without
prejudice to its rights against the defaulting party under this Agreement or
otherwise at law.

6.      MISCELLANEOUS.

    (a) EXPENSES. Each of Cal Dive and CSO will pay all of their respective
expenses, including attorneys' fees and the fees of any consultants, incurred in
connection with the negotiation of this Agreement, the performance of their
respective obligations hereunder and the consummation of the transactions
contemplated hereby; provided, however, that the Joint Venture Entity shall be
responsible for all expenses incurred in connection with its formation and the
preparation of the Formation Documents.

      (b) REMEDIES. Each of the parties hereto shall have all rights and
remedies set forth in this Agreement (including, without limitation, paragraph
6(e)). All remedies hereunder are cumulative and are not exclusive of any other
remedies provided by law or any other agreement or contract to which such person
is a party. Any Person having any rights under any provision of this Agreement
shall be entitled to enforce such rights specifically (without the requirement
of posting a bond or other security), to recover damages by reason of any breach
of any provision of this Agreement and to exercise all other rights granted by
law. Subject to paragraph 6(k) and without limiting the generality of the
foregoing, the parties specifically agree that any breach or threatened breach
of paragraphs 4(a) through 4(c) would cause irreparable injury to the
non-breaching party or the Joint Venture Entity and that money damages would not
provide an adequate remedy to the non-breaching party or the Joint Venture
Entity, and that the non-breaching party or the Joint Venture Entity, as the
case may be, shall accordingly have the right and remedy (i) to obtain an
injunction prohibiting the breaching party from violating or threatening to
violate such provisions, (ii) to have such provisions specifically enforced by
any court of competent jurisdiction, and (iii) to require the breaching party to
account for and pay over to the Joint Venture Entity or the non-breaching party
all compensation, profits, monies, accruals, increments or other benefits

a breach of such provisions.

    (c) ENTIRE AGREEMENT; AMENDMENTS AND WAIVERS. This Agreement (including the
schedules hereto) represents the entire understanding and agreement between the
parties hereto with respect to the subject matter hereof and can be amended,
supplemented or changed, and any provision hereof can be waived, only by written
instrument making specific reference to this Agreement signed by the party
against whom enforcement of any such amendment, supplement, modification or
waiver is sought. No action taken pursuant to this Agreement, including without
limitation, any investigation by or on behalf of any party, shall be deemed to
constitute a waiver by the party taking such action of compliance with any
covenant or agreement contained herein. The waiver by any party hereto of a
breach of any provision of this Agreement shall not operate or be construed as a
further or continuing waiver of such breach or as a waiver of any other or
subsequent breach. No failure on the part of any party to exercise, and no delay
in exercising, any right, power or remedy hereunder shall operate as a 
<PAGE>
                                     - 14 -

waiver thereof, nor shall any single or partial exercise of such right, power or
remedy by such party preclude any other or further exercise thereof or the
exercise of any other right, power or remedy.

    (d) THIRD PARTY BENEFICIARY. The Joint Venture Entity is, upon its
formation, intended to be a third party beneficiary of this Agreement and shall
be entitled to enforce the obligations of the parties to this Agreement to the
same extent as if it were a party hereto.

    (e)    INDEMNIFICATION.

    (i) Cal Dive hereby agrees to indemnify and hold harmless CSO and its
directors, officers, employees, Affiliates, agents, successors and assigns from
and against (A) any and all Losses based upon, attributable to or resulting from
the breach of any covenant or other agreement on the part of Cal Dive under this
Agreement or the enforcement of this Agreement (including, without limitation,
this paragraph 6(e)), and (B) any and all Expenses incident to the foregoing.

    (ii) CSO agrees to indemnify and hold harmless Cal Dive and its directors,
officers, employees, Affiliates, agents, successors and assigns from and against
(A) any and all Losses based upon, attributable to or resulting from the breach
of any covenant or other agreement on the part of CSO under this Agreement or
the enforcement of this Agreement (including, without limitation, this paragraph
6(e)), and

(B) any and all Expenses incident to the foregoing.

      (iii) In the event that any Legal Proceedings shall be instituted or
asserted by any Person in respect of which payment may be sought under this
paragraph 6(e), the indemnified party shall reasonably and promptly cause
written notice of the assertion of any Legal Proceeding of which it has
knowledge which is covered by the indemnities under this paragraph 6(e) to be
forwarded to the indemnifying party; provided, however, that the failure of the
indemnified party to give such reasonable and prompt notice shall not release,
waive or otherwise offset the indemnifying party's obligations hereunder with
respect thereto except to the extent that the indemnifying party can demonstrate
actual loss and prejudice as a result of such failure. The indemnifying party
shall have the right, at its sole option and expense, to be represented by
counsel of its choice, which must be reasonably satisfactory to the indemnified
party, and to defend against, negotiate, settle or otherwise deal with any Legal
Proceeding which relates to any Losses or Expenses indemnified against
hereunder; PROVIDED, HOWEVER, that (i) prior to assuming control of such
defense, the indemnifying party shall verify in writing to the indemnified party
that the indemnifying party will be fully responsible (with no reservation of
any rights) for all liabilities and obligations relating to such claim for
indemnification and that it will provide full indemnification with respect
thereto and (ii) no settlement shall be made without the prior written consent
of the indemnified party, which consent shall not be unreasonably withheld,
conditioned or delayed. If the indemnifying party elects to defend against,
negotiate, settle or otherwise deal with any Legal Proceeding which relates to
any Losses indemnified against hereunder, it shall within thirty (30) days (or
sooner, if the nature of the Legal Proceeding so requires) notify the
indemnified party of its intent to do so. If the indemnifying party elects not
to defend against, negotiate, settle or otherwise deal with any Legal Proceeding
which relates to any Losses and Expenses indemnified against hereunder, fails to
notify the indemnified party of its election as herein provided or contests its
obligation to indemnify the indemnified party for such Losses and Expenses under
this Agreement, the indemnified party may defend against, negotiate, settle or
otherwise deal with such Legal Proceeding. If the indemnified party defends any
Legal Proceeding, then the indemnifying party shall reimburse the indemnified
party for the Expenses of defending such Legal Proceeding upon submission of
periodic bills. The indemnified party may not settle any Legal Proceeding
without the prior written consent of the indemnifying party, which consent shall
not be unreasonably withheld, conditioned or delayed. If the indemnifying party
shall assume the defense of any Legal Proceeding, the indemnified party may
participate, at its own expense, in the defense of 
<PAGE>
                                     - 15 -

such Legal Proceeding; PROVIDED, HOWEVER, such indemnified party shall be
entitled to participate in any such defense with separate counsel at the expense
of the indemnifying party if (i) so requested by the indemnifying party to
participate or (ii) in the reasonable opinion of counsel to the indemnified
party, a conflict or potential conflict exists between the indemnified party and
the indemnifying party that would make such separate representation advisable.
The parties hereto agree to cooperate fully with each other in connection with
the defense, negotiation or settlement of any such Legal Proceeding.

    After any final judgment or award shall have been rendered by a court,
arbitration board or administrative agency of competent jurisdiction and the
expiration of the time in which to appeal therefrom, or a settlement shall have
been consummated, or the indemnified party and the indemnifying party shall have
arrived at a mutually binding agreement with respect to a Legal Proceeding
hereunder, the indemnified party shall forward to the indemnifying party notice
of any sums due and owing by the indemnifying party pursuant to this Agreement
with respect to such matter and the indemnifying party shall be required to pay
all of the sums so due and owing to the indemnified party by wire transfer of
immediately available funds within five business days after the date of such
notice.

    (f) SUCCESSORS AND ASSIGNS. Except as otherwise expressly provided herein,
all covenants and agreements contained in this Agreement by or on behalf of any
of the parties hereto shall bind, and inure to the benefit of the respective
successors and permitted assigns of the parties hereto whether so expressed or
not. Neither party shall transfer or assign this Agreement or any of their
rights or obligations hereunder, whether by operation of law or otherwise,
without the prior written consent of the other party hereto. Any attempted
transfer or assignment of this Agreement or any rights or obligations hereunder
in violation of this provision shall be void AB INITIO.

    (g) SEVERABILITY_. Whenever possible, each provision of this Agreement shall
be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Agreement is held to be prohibited by or invalid
under applicable law, such provision shall be ineffective only to the extent of
such prohibition or invalidity, without invalidating the remainder of this
Agreement.

    (h) COUNTERPARTS. This Agreement may be executed simultaneously in two or
more counterparts, any one of which need not contain the signatures of more than
one party, but all such counterparts taken together shall constitute one and the
same Agreement.

    (i) SECTION HEADINGS: INTERPRETATION. The section headings of this Agreement
are inserted for convenience only, do not constitute a part of this Agreement
and are to be given no effect in the construction or interpretation of this
Agreement. The use of the word "including" in this Agreement shall be by way of
example rather than by limitation.

    (j) GOVERNING LAW: SUBMISSION TO JURISDICTION; CONSENT TO SERVICE OF
PROCESS.

    (i) Except as expressly provided in paragraph 6(k), the internal law, and
not the conflicts of law principles, of the State of Delaware shall govern this
Agreement as well as the construction, validity and interpretation of this
Agreement and the exhibits and schedules hereto.

    (ii) Solely to the extent permitted by paragraph 6(k) hereof, each of the
parties hereto hereby irrevocably submit for itself and its property to the
non-exclusive jurisdiction of any federal or state court located within the
State of New York over any Dispute and each party hereby irrevocably agrees that
all claims in respect of such Dispute or any action, suit or proceeding related

<PAGE>
                                     - 16 -

paragraph 6(k) hereof, may be heard and determined in such courts. The parties
hereby irrevocably waive, to the fullest extent permitted by applicable law, any
objection which they may now or hereafter have to the laying of venue of any
Dispute brought in such court or any defense of inconvenient forum for the
maintenance of such Dispute, provided that relief sought in any action, suit or
proceeding relating thereto is of the nature expressly permitted by paragraph

an Award or a judgment in any such Dispute may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.

    (iii) Each of the parties hereto hereby consents to process being served by
any party to this Agreement in any suit, action or proceeding of the nature
expressly permitted by paragraph 6(k) hereof by the delivery or mailing of a
copy thereof in accordance with the provisions of paragraph 6(1).

    (iv) Nothing in this paragraph (6j) shall affect the rights of the parties
to commence any action, suit or proceeding of the nature expressly permitted by
paragraph 6(k) hereof in any other forum or to serve process in any such action,
suit or proceeding in any other manner permitted by law.

    (k) ARBITRATION.

    (i) Any claim, dispute or other disagreement other than a Management
Disagreement (each, a "Dispute") between Cal Dive and CSO or between Cal Dive or
CSO, on the one hand, and the Joint Venture Entity, on the other hand, arising
out of or relating to this Agreement, any contract between either party and the
Joint Venture Entity or the Formation Documents, or any of the transactions
contemplated hereby or thereby, shall be finally settled by arbitration in
accordance with the terms of this subparagraph 6(k)(i); provided that any party
shall in any event have the right to seek and obtain equitable relief during the
pendency of such Dispute pursuant to subparagraph 6(k)(ii) hereof. In the event
of any Dispute, any party may serve written notice of such Dispute on any other
party and each party to such Dispute shall undertake in good faith to resolve
such Dispute. If the parties cannot agree to resolve such Dispute within 15 days
after such written notice, any party to such Dispute may, by further written
notice (the "Arbitration Notice") to the other party, commence an arbitration
proceeding by bringing the Dispute to an arbitration panel selected as provided
below. The Arbitration Notice shall be filed simultaneously with the
International Chamber of Commerce in New York, New York, and shall contain a
description of the amount in controversy, the nature of the Dispute and the
paragraph(s) of this Agreement to which such Dispute relates. Disputes shall be
decided by an arbitration panel comprised of three arbitrators (each of whom
shall be a practicing lawyer knowledgeable and experienced in matters of
commercial and construction law), one arbitrator to be selected by Cal Dive, a
second arbitrator to be selected by CSO, and the third arbitrator (the
"Independent Arbitrator"), who will be the Chairman of the arbitration panel, to
be appointed by the first two arbitrators. In the event the first two
arbitrators fail to agree on the appointment of the Independent Arbitrator
within 15 days, the Independent Arbitrator shall be appointed by the
International Chamber of Commerce in New York, New York. In the event that any
arbitrator shall resign, be unable or otherwise fail to perform his or her
duties, each party shall immediately notify the other parties of such
resignation, inability or failure, and a replacement shall immediately be
selected by the party who selected such arbitrator in the first instance, or, if
the arbitrator to be replaced is the Independent Arbitrator, then the parties
shall attempt in good faith to appoint a mutually agreeable replacement
Independent Arbitrator. If the parties fail to agree on such replacement within
15 days, either party may request that the International Chamber of Commerce in
New York, New York appoint such replacement Independent Arbitrator. The
arbitration panel shall conduct the arbitration in accordance with the Rules of
Arbitration of the International Chamber of Commerce then in effect, except to
the extent such rules are inconsistent with the provisions of this subparagraph
6(k)(i). The parties shall prepare in writing a statement of their positions,
together with counterclaims, with supporting facts, data, and affidavits, if
any, for the arbitration panel and shall submit such statement to the
arbitration panel 
<PAGE>
                                     - 17 -

within 15 days after it is selected, but, in any event, within 60 days after
service of the Arbitration Notice. The arbitration panel shall give all parties
the opportunity to make an oral presentation to the arbitration panel in the
presence of the other party if either party so requests. The parties shall have,
for a period of 180 days after service of the Arbitration Notice (the "Discovery
Period"), all rights of discovery provided by the New York Civil Practice Law
and Rules then obtaining, except, unless otherwise agreed, that all responses to
discovery requests shall be served within 10 days of such discovery request, and
no discovery request may be served after the date 10 days before the termination
of the Discovery Period. Subject to the proviso in the first sentence of this
subparagraph 6(k)(i) and to subparagraph 6(k)(ii) hereof, the arbitration panel
shall assume exclusive jurisdiction over the Dispute, may order interim
equitable relief (which shall be specifically enforceable as if it were a final
Award, as hereinafter defined), and shall be required to make a final binding
determination (the "Award"). The Award shall not be subject to appeal to or
review by any court or administrative body except as set forth in Section 10(a)
of the Federal Arbitration Act, codified as 9 U.S.C.A. ss.10(a) (West Supp.
1997). The Award shall determine (A) whether each party's obligations under this
Agreement were met and (B) what damages or remedies (which may include final
equitable relief) are due to the respective parties under the terms of this
Agreement. The agreement to arbitrate contained in this paragraph 6(k) shall be
specifically enforceable under the prevailing arbitration law, and shall survive
termination of this Agreement. Judgment upon the Award rendered by the
arbitration panel may be entered in accordance with applicable law in any court
having jurisdiction therefor. Each party shall bear its own costs and expenses
for arbitration, subject to reimbursement as determined by the arbitration panel
in the Award. Arbitration shall, unless the parties otherwise agree in writing,
take place in New York, New York.

    (ii) Nothing contained in this paragraph 6(k) shall preclude, or be deemed,
construed or interpreted to preclude, any party from seeking interim equitable
relief from a court of competent jurisdiction against the other party, where
circumstances so require, except that no party shall be entitled to seek a stay
of any arbitration proceeding brought hereunder. The parties agree that, upon
the application of any of the parties, and whether or not an arbitration
proceeding has yet been initiated pursuant to this paragraph 6(k), all courts
having jurisdiction are hereby authorized to (A) issue and enforce in any lawful
manner such temporary restraining orders, preliminary injunctions and other
interim measures of relief as may be necessary to prevent harm to a party's
interests or as otherwise may be appropriate pending the conclusion of
arbitration proceedings pursuant to this paragraph 6(k), and/or (B) enter into
and enforce in any lawful manner such judgments for permanent equitable relief
as may be necessary to prevent harm to a party's interests or as otherwise may
be appropriate following the issuance of the Award.

                      ANNUAL INCENTIVE COMPENSATION PROGRAM

                         ===============================

      By now, you should all be familiar with Cal Dive's MISSION TRIANGLE.

The concept inherent in the MISSION TRIANGLE is that our corporate goals of
Profitability and Client Satisfaction are attainable only through a team effort
and commitment to safety, planning, professionalism and quality. What also needs
to be understood is that in the long-term you cannot have profitability without
satisfied clients and conversely, you will not have the means of satisfying
those clients unless the company is generating sufficient levels of profit.

Cal Dive's 1995 Incentive Compensation Program is designed to provide financial
rewards to certain key individuals for their contribution towards achieving our
corporate goals of Profitability and Client Satisfaction. Every individual who
is eligible for Incentive Compensation should consider himself responsible for
insuring that the company achieve these goals. Anyone who does not fully
understand how they might contribute to this should visit with Jerry Reuhl about
this issue.

                            PROJECT ENGINEERING GROUP

The Project Engineering Group was formed in May 1992 to take a lead role in all
phases of a project's life, from bidding through planning and execution, on to
final invoice. The performance of this group is key to achieving our corporate
goals of Profitability and Client Satisfaction.

Each Project Engineer's incentive compensation opportunity will be based on the
following:

      1)    Attaining a "subsea division" gross profit level of $9,225,000 (the
            goal) will result in an opportunity equal to 10% of the Project
            Engineer's base salary.

      2)    A bonus pool will be established equal to (a) 5% of the first one
            million dollars in excess of the goal, plus (b) 10% of any subsea
            division gross profits in excess of the goal plus $1 million
            dollars.

                                                                        
Discretionary bonuses may be paid to members of the Project Engineering staff at
the discretion of the V. P. of Project Engineering. The remainder of the bonus
pool will be available as an incentive compensation opportunity for the Project
Engineers, (the V. P. of Project Engineering will be considered a Project
Engineer for bonus calculation purposes, including Paragraph #1 above), in
direct proportion to the ratio of the participants base salaries.

Each participants opportunity will be awarded based as follows:

      1)    50% of the total opportunity will be awarded based on achieving the 
            financial goals.

      2)    From 0 to 50% of the total opportunity will be awarded based on a
            subjective evaluation by the Company's executive management on the
            individual's efforts, contribution, and success in developing client
            satisfaction.

Any portion of the opportunity that is not awarded will be accrued for and added
to the appropriate groups opportunity for the following years Incentive
Compensation Program.

If the company purchases or otherwise acquires new assets with the expectation
of increasing the gross profit of the subsea division, the gross profit levels
in 1, 2(a) and 2(b) above will be adjusted upward to allow for a reasonable
return to the company before the bonus opportunity kicks in. This adjustment
will be based on the economics presented to the Board of Directors as
justification for the new equipment or service, and will be made by the
executive management of the Company. As you will notice, this year's goal has
been increased by $1,225,000 over the 1994 goal to reflect the addition of our
new D.P. vessel for six months. (The 1996 plan will reflect a goal based on a
full year of operation.)

pool will be available as an incentive compensation opportunity for the Account
Managers, (the Marketing and Sales Coordinator will be considered an Account
Manager for bonus calculation purposes, including Paragraph #1 above), in direct
proportion to the ratio of the participants base salaries.

Each participant's opportunity will be awarded based as follows:

      1)    1/3 of the total opportunity will be awarded based on achieving the 
            financial goals.

      2)    From 0 to 1/3 of the total opportunity will be awarded based on a
            subjective evaluation by the Company's executive management on the
            individual's efforts, contribution, and success in developing client
            satisfaction.

      3)    From 0 to 1/3 of the total opportunity will be awarded based on a

rights it may have to enforce the terms of this Section 5 (the "Waiver), during

noncompetition provisions contained in this Section 5 terminate or the Waiver is
delivered to Employee, whichever is earlier, the Company will pay to Employee an

hereby canceled and replaced in its entirety by this Agreement.

of the Company generates, authors or contributes to any invention, design, new

reduced to practice or comprising Confidential Information), any copyrightable
work (whether or not comprising Confidential Information) or any other form of
Confidential Information relating directly or indirectly to the Company's
business as prior hereto, now or hereinafter conducted (collectively,
"Intellectual Property"), Employee acknowledges that such Intellectual Property
is the exclusive property of the Company and hereby assigns all right, title and
interest in and to such Intellectual Property to the Company. Any copyrightable

copyright therein. Employee shall promptly and fully disclose all Intellectual
Property to the Company and shall cooperate with the Company to protect the
Company's interest in and rights to such Intellectual Property, including
without limitation providing reasonable assistance in securing patent protection
and copyright registrations and executing all documents as reasonably requested
by the Company, whether such requests occur prior to or after termination of
Employee's employment with the Company.

            (b) In accordance with Minnesota Statutes, Chapter 181, Section
181.78, Employee is hereby advised that no provision of this Agreement is
intended to assign any of Employee's rights in an invention for which no
equipment, supplies, facility or trade secret information of the Company was
used and which was developed entirely on the Employee's own time, and which does
not relate directly to the business of the Company or to the Company's actual or
demonstrably anticipated research or development, or which does not result from
any work performed by the Employee for the Company.

            (c) As requested by the Company from time to time and upon the
termination of Employee's employment with the Company for any reason, Employee
shall promptly deliver to the Company all copies and embodiments, in whatever
form, of all Confidential Information or Intellectual Property in Employee's
possession or within his control (including, but not limited to, written
records, notes, photographs, manuals, notebooks, documentation, program
listings, flow charts, magnetic media, disks, diskettes, tapes and all other
materials containing any Confidential Information or Intellectual Property)
irrespective of the location or form of such material and, if requested by the
Company, shall provide the Company with written confirmation that all such
materials have been delivered to the Company.

SECTION  7. TERMINATION OF AGREEMENT.

Company at any time during the Employment Term for "Cause", in which event

preceding sentence, "Cause" shall mean: (i) any breach or threatened breach by
Employee of any of his agreements contained in Section 4, 5 or 6 hereof; (ii)
repeated or willful neglect by Employee in performing any duty or carrying out
any responsibility assigned or delegated to him pursuant to Section 1(b) hereof,

any criminal act involving moral turpitude or a felony which results in an
arrest or indictment, or the commission by Employee, based on reasonable proof,
of any act of fraud or embezzlement involving the Company or its customers or
suppliers. In the event that the Company elects to terminate this Agreement for
Cause, it will give Employee written notice of such termination, and, at the
Company's discretion, Employee's employment will terminate sixty (60) days
thereafter.

      (b) TERMINATION UPON DEATH. This Agreement shall terminate automatically
upon the death of Employee during the Employment Term. In such event, the
Company shall be obligated to pay to Employee's estate, or to such person or
persons as he may designate in writing to the Company, (i) through the last day
of the fiscal year in which Employee's death shall have occurred, the salary
(payable in the same manner as described in Section 2(a) hereof) to which
Employee would have been entitled under Section 2(a) hereof had such death not
occurred, and (ii) as soon as reasonably practicable after Employee's death, any
accrued but, as of the date of such death, unpaid Incentive Bonus (or, if such
death shall have occurred after the first three (3) months of the Company's
fiscal year, any prorated portion thereof).

      (c) TERMINATION UPON DISABILITY. This Agreement may be terminated by the
Company at any time during the Employment Term in the event that Employee shall
have been unable, because of "Disability" (as hereinafter defined), to perform
his principal duties for the Company for a cumulative period of six (6) months
within any eighteen (18) month period. Prior to Employee's termination for
Disability as provided herein, he shall remain eligible to receive the
compensation and benefits set forth in Section 2 and Section 3 hereof. Upon such
termination, Employee shall be entitled to receive as soon as reasonably
practicable thereafter, any accrued, but as of the date of such termination,
unpaid Incentive Bonus (or, if such termination shall have occurred after the
first

                                        4
<PAGE>
three (3) months of the Company's fiscal year, any prorated portion thereof).
For purposes of this Section 7(c), "Disability" shall mean any physical or
mental condition of Employee which shall substantially impair his ability to
perform his principal duties hereunder. In the event that the Company elects to
terminate this Agreement by reason of Disability under this Section 7(c), it
will give written notice of such termination, and, at the Company's discretion,
Employee's employment will terminate sixty (60) days thereafter.

      (d) EFFECT OF TERMINATION. In the event that this Employee is terminated
pursuant to any paragraph of this Section 7, Employee shall thereafter have no
further rights under this Agreement, except for those explicitly set forth in
the particular paragraph of this Section 7 which served as the Company's basis
for such termination. Notwithstanding any such termination, the covenants and
agreements of Employee contained in Sections 4, 5 (a) (so long as payments under
Section 5(a) are continued as therein described), 5 (b) and 6 hereof shall
survive and remain in full force and effect.

Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provisions of any other jurisdiction, and this Agreement shall be
reformed, construed and enforced in such jurisdictions if such invalid, illegal
or unenforceable provision had never been contained herein. The parties agree

agreement and understanding among the parties and supersedes and preempts any

entitled to enforce its rights under this Agreement specifically, to recover
damages and costs (including reasonable attorneys fees) caused by any breach of
any provision of this Agreement and to exercise all other rights existing in its
favor. The parties hereto agree and acknowledge that Employee's breach of any
term or provision of this Agreement shall materially and irreparably harm the
Company, that money damages shall accordingly not be an adequate remedy for any
breach of the provisions of this Agreement and that any party in its sole
discretion and in addition to any other remedies it may have at law or in equity
may apply to any court of law or equity of competent jurisdiction (without
posting any bond or deposit) for specific performance and/or other injunctive
relief in order to enforce or prevent any violations of the provisions of this
Agreement.

            (i) AMENDMENT AND WAIVER. The provisions of this Agreement may be
amended and waived only with the prior written consent of the Company and

for such termination. In the event that during the Employment Term Employee (i)
is terminated by the Company without "Cause" or (ii) voluntary resigns from his
employment with the Company and as a director of the Company, the Company shall
be obligated to purchase as promptly as reasonably practicable after such

by the Company. Employee shall take all appropriate steps to safeguard
Confidential Information and to protect it against disclosure, misuse,
espionage, loss and theft.

      (b) As used in this Agreement, the term "Confidential Information" means

Information shall not include any information that has been published in a form
generally available to the public prior to the date Employee proposes to
disclose or use such information other than as a result of disclosure by
Employee in violation of this Agreement. Information shall not be deemed to have
been published merely because individual portions of the information have been
separately published, but only if all material features comprising such
information have been published in combination.

<PAGE>
not patentable or reduced to practice or comprising Confidential Information),

equipment, supplies, facility or trade secret information of the Company was
used and which was developed entirely on the Employee's own time, and which does
not relate directly to the business of the Company or to the Company's actual or
demonstrably anticipated research or development, or which does not result from

listings, flow charts, magnetic media, disks, diskettes, tapes and all other
materials containing any Confidential Information or Intellectual Property)

Company, shall provide the Company with written confirmation that all such
materials have been delivered to the Company.

persons as he may designate in writing to the Company, (i) through the last day
of the fiscal year in which Employee's death shall have occurred, the salary
(payable in the same manner as described in Section 2(a) hereof) to which
Employee would have been entitled under Section 2(a) hereof had such death not
occurred, and (ii) as soon as reasonably practicable after Employee's death, any

Company, that money damages shall accordingly not be an adequate remedy for any
breach of the provisions of this Agreement and that any party in its sole
discretion and in addition to any other remedies it may have at law or in equity
may apply to any court of law or equity of competent jurisdiction (without
posting any bond or deposit) for specific performance and/or other injunctive

                          1997 LONG TERM INCENTIVE PLAN
                                       OF
                          CAL DIVE INTERNATIONAL, INC.

- --------------------------------------------------------------------------------

      On November 2, 1995, the Cal Dive Board approved the 1995 LONG TERM
INCENTIVE PLAN OF CAL DIVE INTERNATIONAL, INC. (Attachment 1) which was
subsequently approved by the Shareholders of the Company.

      The Plan provided for issuance of up to 600,000 shares of Common Stock of
the Company, representing approximately 5% of the then issued and outstanding
Common Stock of the Company.

      As of this date, awards for 476,500 shares at a strike price of $4.50 per
share are issued (Attachment 2) pursuant to a standard "Award Agreement"
(Attachment 3).

      Whereas the 1997 Amended and Restated Shareholders Agreement dated as of
April 10, 1997, contemplates a "Stock Option Plan" providing for the granting to
employees or Directors rights to purchase in the aggregate, when combined with
all other outstanding options or other rights to purchase Common Stock from the
Company, up to 10% (as adjusted for any subsequent stock splits, stock
dividends, recapitalizations or similar events) of the issued and outstanding
Common Stock of the Company; and

      Whereas the 1995 Long Term Incentive Plan allows (pursuant to Article 10)
for the modification of the Plan by the Board (subject to subsequent Shareholder
approval);

      Management hereby recommends the following changes to the Plan be adopted:

      1) Amend "Participant" to read "means an employee OR DIRECTOR . . ."

      2) Amend Article 4 to read:

            COMMON STOCK AVAILABLE FOR AWARDS: There shall be available for
Awards granted wholly or partly in Common Stock (including rights or options
which may be exercised for or settled in Common Stock) during the term of this
Plan, up to (but not to exceed) 10% of the issued and outstanding Common Stock
(as adjusted for any subsequent stock splits, stock dividends,
recapitalizations, or similar events). This 10% will be calculated in the
aggregate, when combined with all other outstanding options or other rights to
purchase Common Stock. The Board of Directors and the appropriate officers of
the Company shall from time to time take whatever actions are necessary to file
required documents with governmental authorities and stock exchanges and
transaction reporting systems to make shares of Common Stock available for
issuance pursuant to Awards. Common Stock related to Awards that are forfeited
or terminated, expire unexercised or if settled in a manner such that all or
some of the shares covered by an Award are not issued to a Participant, or are
exchanged for Awards that do not involve Common Stock, shall immediately become
available for Awards hereunder. The Committee may from time to time adopt and
observe such procedures concerning the counting of shares against the Plan
maximum as it may deem appropriate under Rule 16b-3.

                                 Page 1 of 2
<PAGE>
      Furthermore, Management hereby recommends that Awards be made as follows,
using the Award Agreement (Attachment 4) based on an exercise price of $9.50 per
share, pro rata annual vesting for five (5) years:

      Lou Tapscott......................................................70,000
      Lynn Smith.........................................................5,000
      Ken Duell.........................................................25,000
      George Friedel....................................................25,000
      Chris Hale........................................................15,000
      Stanley Kellogg...................................................25,000
      Jack Lounsbury....................................................10,000
      John Odusch.....................................................  10,000
                                    TOTAL                              185,000

      As a result of these awards, the Company responsibility under all Awards
will equal 661,500 shares with a total issued and outstanding 11,627,801 shares
or + 5.7%.

number of shares of Common Stock at a specified price that is not less than the
Fair Market Value of the Common Stock on the date of grant. A stock option may
be in the form of an incentive stock option ("ISO") which, in addition to being
subject to applicable terms, conditions and limitations established by the
Committee, complies with Section 422 of the Code and may, at the discretion of
the Committee, be converted at any time to a Stock Appreciation Right as
specified in the Participant's Stock Option Agreement.

      (b) STOCK APPRECIATION RIGHT. An award may consist of a right to receive a
payment, in cash or Common Stock, equal to the excess of the Fair Market Value
or other specified valuation of a specified number of shares of Common Stock on
the date the stock appreciation right ("SAR") is exercised over a specified
"Exercise Price" as set forth in the applicable Award Agreement.

      (c) STOCK AWARD. An Award may consist of Common Stock or may be
denominated in units of Common Stock. All or part of any stock award may be
subject to conditions established by the Committee, and set forth in the Award
Agreement, which may include, but are not limited to, continuous service with
the Company and its Subsidiaries, accelerated vesting based upon events such as
a change in control of the Company, achievement of specific business objectives,
increases in specified indices, attaining specified growth rates and other
comparable measurements of performance and the right of the Committee to convert
the Award to a Stock Appreciation Right. Such Awards may be based on Fair Market
Value or other specified valuations. The certificates evidencing shares of
Common Stock issued in connection with a stock award shall contain appropriate
legends and restrictions describing the terms and conditions of the restrictions
applicable thereto.

      (d) CASH AWARD. An award may be denominated in cash with the amount of the
eventual payment subject to future service and such other restrictions and
conditions as may be established by the Committee, and set forth in the Award
Agreement, including, but not limited to the same conditions for a Stock Award.

      7.    PAYMENT OF AWARDS.

      (a) GENERAL. Payment of Awards may be made in the form of cash or Common
Stock or combinations thereof and may include such restrictions as the Committee
shall determine, including in the case of Common Stock, restrictions on transfer
and forfeiture provisions. As used herein, "Restricted Stock" means Common Stock
that is restricted or subject to forfeiture provisions.

      (b) DEFERRAL. With the approval of the Committee, payments may be
deferred, either in the form of installments or a future lump sum payment. The
Committee may permit selected Participants to elect to defer payments of some or
all types of Awards in accordance with procedures established by the Committee.
Any deferred payment, whether elected by the Participant or specified by the
Award Agreement or by the Committee, may be forfeited if and to the extent that
the Award Agreement so provides.

      (c) DIVIDENDS AND INTEREST. Dividends or dividend equivalent rights may be
extended to and made part of any Award denominated in Common Stock or units of
Common Stock, subject to such terms, conditions and restrictions as the
Committee may establish. The Committee may also establish rules and procedures
for the crediting of interest on deferred cash payments and dividend equivalents
for deferred payment denominated in Common Stock or units of Common Stock.

      (d) SUBSTITUTION OF AWARDS. At the discretion of the Committee, a
Participant may be offered an election to substitute an Award for another Award
or Awards of the same or different type.

      8. STOCK OPTION EXERCISE. The price at which shares of Common Stock may be
purchased under a stock option shall be paid in full at the time of exercise in
cash or, if permitted by the Committee, by means of tendering Common Stock or
surrendering another Award, including Restricted Stock, valued at Fair Market
Value on the date of exercise, or any combination thereof. The Committee shall
determine acceptable methods for tendering Common Stock or other Awards to
exercise a stock option as it deems appropriate. If permitted by the Committee,
payment may be made by successive exercises by the Participant. The Committee
may provide for loans from the Company to permit the exercise or purchase of
Awards and may provide for procedures to permit the exercise or purchase of
Awards by use of the proceeds to be received from the sale of Common Stock
issuable pursuant to an Award. Unless otherwise provided in the applicable Award
Agreement, in the event shares of Restricted Stock are tendered as consideration
for the exercise of a stock option, a number of the shares issued upon the
exercise of the stock option, equal to the number of shares of Restricted Stock
used as consideration therefor, shall be subject to the same restrictions as the
Restricted Stock so submitted as well as any additional restrictions that may be
imposed by the Committee.

                                 Page 6 of 2

<PAGE>
      9. TAX WITHHOLDING. The Company shall have the right to deduct applicable
taxes from any Award payment and withhold, at the time of delivery or vesting of
cash or shares of Common Stock under this Plan, an appropriate amount of cash or
number of shares of Common Stock or a combination thereof for payment of taxes
required by law or to take such other action as may be necessary in the opinion
of the Company to satisfy all obligations for withholding of such taxes. The
Committee may also permit withholding to be satisfied by the transfer to the
Company of shares of Common Stock theretofore owned by the holder of the Award
with respect to which withholding is required. If shares of Common Stock are
used to satisfy tax withholding, such shares shall be valued based on the Fair
Market Value when the tax withholding is required to be made.

      10. AMENDMENT, MODIFICATION, SUSPENSION OR TERMINATION. The Board may
amend, modify, suspend or terminate this Plan for the purpose of meeting or
addressing any changes in legal requirements or for any other purpose permitted
by law except that (i) no amendment or alteration that would impair the rights
of any participant under any Award previously granted to such Participant shall
be made without such Participant's consent and (ii) no amendment or alteration
shall be effective prior to approval by the Company's stockholders to the extent
such approval is then required pursuant to Rule 16b-3 in order to preserve the
applicability of any exemption provided by such rule to any Award then
outstanding (unless the holder of such Award consents) or to the extent
stockholder approval is otherwise required by applicable legal requirements.

      11. TERMINATION OF EMPLOYMENT. Continuous employment shall be a condition
to exercise of all Awards granted under this Plan. All Awards shall
automatically be void on the termination of employment of a Participant (for any
reason including death or disability) and such Participant shall thereafter have
no rights relative to such Award.

      12. ASSIGNABILITY. Unless otherwise determined by the Committee and
provided in the Award Agreement, no Award or any other benefit under this Plan
shall be assignable or otherwise transferable except by will or the laws of
descent and distribution or pursuant to a qualified domestic relations order as
defined by the Code or Title I of the Employee Retirement Income Security Act,
or the rules thereunder. The Committee may prescribe and include in applicable
Award Agreements other restrictions on transfer. Any attempted assignment of an
Award or any other benefit under this Plan in violation of this Paragraph 12
shall be null and void.

      13.   ADJUSTMENTS.

      (a) The existence of outstanding Awards shall not affect in any manner the
right or power of the Company or its stockholders to make or authorize any or
all adjustments, recapitalizations, changes of control or other changes in the
capital stock of the Company or any merger or consolidation of the Company, or
any issue of bonds, debentures, preferred or prior preference stock (whether or
not such issue is prior to, on a parity with or junior to the Common Stock) or
the dissolution or liquidation of the Company, or any sale or transfer of all or
any part of its assets or business, or any other corporate act or proceeding of
any kind, whether or not of a character similar to that of the acts or
proceedings enumerated above.

      (b) In the event of any subdivision or consolidation of outstanding shares
of Common Stock or declaration of a dividend payable in shares of Common Stock
or recapitalizations or 

                                 Page 7 of 2

<PAGE>
reclassification or other transaction involving an increase or reduction in the
number of outstanding shares of Common Stock, the Committee may adjust
proportionally (i) the number of shares of Common Stock reserved under this Plan
and covered by outstanding Awards denominated in Common Stock or units of Common
Stock; (ii) the exercise or other price in respect of such Awards; and (iii) the
appropriate Fair Market Value and other price determinations for such Awards. In
the event of any consolidation or merger of the Company with another corporation
or entity or the adoption by the Company of a plan of exchange affecting the
Common Stock or any distribution to holders of Common Stock of securities or
property (other than normal cash dividends or dividends payable in Common
Stock), the Committee shall make such adjustments or other provisions as it may
deem equitable, including adjustments to avoid fractional shares, to give proper
effect to such event. In the event of a corporate merger, consolidation,
acquisition of property or stock, separation, change of control or liquidation,
the Committee shall be authorized to issue or assume stock options, regardless
of whether in a transaction to which Section 424(a) of the Code applies, by
means of substitution of new options for previously issued options or an
assumption of previously issued options, or to make provision for the
acceleration of the exercisability of, or lapse of restrictions with respect to,
Awards and the termination of unexercised options in connection with such
transaction.

      14. RESTRICTIONS. No Common Stock or other form of payment shall be issued
with respect to any Award unless the Company shall be satisfied based on the
advice of its counsel that such issuance will be in compliance with applicable
federal and state securities laws. It is the intent of the Company that this
Plan comply with Rule 16b-3 with respect to persons subject to Section 16 of the
Exchange Act unless otherwise provided herein or in an Award Agreement, that any
ambiguities or inconsistencies in the construction of this Plan be interpreted
to give effect to such intention, and that if any provision of this Plan is
found not to be in compliance with rule 16b-3, such provision shall be null and
void to the extent required to permit this Plan to comply with Rule 16b-3.
Certificates evidencing shares of Common Stock delivered under this Plan may be
subject to such stop transfer orders and other restrictions as the Committee may
deem advisable under the rules, regulations and other requirements of the
Securities and Exchange Commission, any securities exchange or transaction
reporting system upon which the Common Stock is then listed and any applicable
federal and state securities law. The Committee may cause a legend or legends to
be placed upon any such certificates to make appropriate reference to such
restrictions.

      15. UNFUNDED PLAN. Insofar as it provides for Awards of Common Stock, cash
or rights thereto, this Plan shall be unfunded. Although bookkeeping accounts
may be established with respect to Participants who are entitled to cash, Common
Stock or rights thereto under this Plan, any such accounts shall be used merely
as a bookkeeping convenience. The Company shall not be required to segregate any
assets that may at any time be represented by cash, Common Stock or rights
thereto, nor shall this Plan be construed as providing for such segregation, nor
shall the Company nor the Board nor the committee be deemed to be a trustee of
any cash, Common Stock or rights thereto to be granted under this Plan. Any
liability or obligation of the Company to any Participant with respect to a
grant of cash, Common Stock or rights thereto under this Plan shall be based
solely upon any contractual obligations that may be created by this Plan and any
Award Agreement, and no such liability or obligation of the Company shall be
deemed to be secured by any pledge or other encumbrance on any property of the
Company. Neither the Company nor the Board nor the Committee shall be required
to give any security or bond for the performance of any obligation that may be
created by this Plan.

      16. GOVERNING LAW. This Plan and all determinations made and actions taken
pursuant hereto, to the extent not otherwise governed by mandatory provisions of
the Code or the securities laws of the United States, shall be governed by and
construed in accordance with the laws of the State of Minnesota.

      17. EFFECTIVE DATE OF PLAN. This Plan shall be effective as of the date
(the "Effective Date") it is approved by the Board of Directors of the Company.
Notwithstanding the foregoing, the adoption of this Plan is expressly
conditioned upon the approval by the holders of a majority of shares of Common
Stock present, or represented, and entitled to vote at a meeting of the
Company's stockholders held on or before November 3, 1995. If the stockholders
of the Company should fail to approve this Plan prior to such date, this Plan
shall terminate and cease to be of any further force or effect and all grants of
Awards hereunder shall be null and void.
