ITEM 1.  BUSINESS

GENERAL

         Marine Drilling Companies, Inc. (collectively with its subsidiaries,
the "Company") was incorporated in Texas in January 1990.  Since 1966, the
Company or its predecessors has been engaged in offshore contract drilling of
oil and gas wells for independent and major oil and gas companies.  As of March
6, 1995, the Company owned and operated a fleet of thirteen mobile offshore
jack-up drilling rigs, consisting of four independent leg cantilever jack-ups
and nine mat supported jack-ups.  On that date, eleven of the Company's
thirteen rigs were located in the U.S. Gulf of Mexico, one was in the Bay of
Campeche and one was in transit to the U.S. Gulf of Mexico from Southeast Asia.
The Company currently derives substantially all of its revenues from offshore
drilling in the U.S. Gulf of Mexico and in the Bay of Campeche.  The Company's
rigs could, with certain modifications, work in other areas, however, the
Company's rigs are not suitable for those areas, such as the North Sea, that
require hostile environment operating capabilities.

         The Company's strategy is to strive to maintain its position as a
significant provider of offshore drilling services in its present markets and
to continue to diversify, insofar as financially and operationally practicable,
into other international offshore drilling markets.  The Company also intends
to seek business combinations and to make acquisitions of additional drilling
rigs which, over the long term, the Company believes will benefit its
shareholders.

         The Company was significantly restructured and recapitalized in 1992
and early 1993 (the "Recapitalization").  See Item 7 "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- The
Recapitalization" for further information.

INDUSTRY CONDITIONS AND COMPETITION

         Demand for offshore drilling services is primarily driven by the
economics of oil and gas exploration, development and production, which in
turn, are closely tied to oil and gas prices.  Since the mid-1980's oil and gas
prices have been volatile and generally lower than prices experienced during
the early 1980's.  As a result, demand for offshore drilling services has been
volatile and generally lower than during the early 1980's.  In addition, during
the late 1970's and early 1980's, the industry built a substantial number of
new offshore drilling rigs.  The combination of (i) generally lower oil and gas
prices, (ii) increased rig supply and (iii) lower demand for offshore drilling
services has resulted in many periods of depressed pricing and utilization for
most of the world's offshore drilling markets.

         Pricing and rig water depth capabilities are generally the most
important competitive factors in the drilling industry.  Other competitive
factors include the technical capabilities of specialized drilling equipment
and personnel, operational experience, rig suitability, efficiency, equipment
condition, safety record, reputation and customer relations.  The Company
believes that it competes favorably with respect to these factors.

         The magnitude of the Company's contract drilling revenues is dependent
upon rig utilization and pricing.  These variables are affected by competitive
conditions and the amount of exploration and development activity conducted by
oil and gas companies.  As previously stated, this activity is strongly
influenced by the current and projected prices of oil and natural gas.  To
provide a recent historical perspective, oil and gas prices for 1990 through
1994 are set forth in the following graph:

    Worldwide Offshore Market Conditions

         As the following graph illustrates, from the beginning of 1992 to the
end of 1994, the number of jack-up rigs available worldwide has declined only
slightly (approximately 2.5%).  Jack-up rig demand during that period has
varied from a low of 257 rigs (64% utilization) during the second quarter of
1992 to a high of 312 rigs (80% utilization).  During 1994, the average
worldwide supply, demand and utilization of jack-up rigs was 391, 296 and 75%,
respectively, as compared to 1993 during which these statistics were 393, 308
and 78%, respectively.  Although it would appear that the small variance
between the statistics for 1994 and 1993 might imply a minimal decrease in day
rates in 1994, other trends emerge due to the mobile nature of jack-up rigs.
As discussed later in this section, there was a significant movement of jack-up
rigs during 1993 and 1994 into the U.S. Gulf of Mexico from other worldwide
drilling markets.  These mobilizations generally occurred for two reasons --
(i) strong natural gas prices throughout 1993 and early 1994 led to increased
demand for jack-ups in the U.S. Gulf of Mexico and (ii) oil prices were
generally weak during the latter half of 1993 and the first quarter of 1994
which had a depressing effect on the demand for drilling services in many
jack-up markets outside the U.S. Gulf of Mexico.

         Due to the extremely competitive nature of the offshore drilling
business, changes in the demand for drilling services among different markets
cause many drilling contractors to react by moving several rigs away from their
weaker markets to stronger markets, thereby creating an increased supply of
rigs in the stronger market.  This increased rig supply in the stronger market
will quickly cause day rates to deteriorate unless rig demand increases at or
above the rate of growth in rig supply.  It seems that the participants in the
offshore drilling industry often have a tendency to move too many rigs into the
stronger market -- causing it to suffer utilization and day rate deterioration.
The tendency of the offshore drilling industry to "over-mobilize" rigs among
markets has been exacerbated by the volatile nature of oil and gas prices since
the mid-1980's.  As the prices of these commodities fluctuate, oil and gas
companies quickly adjust their drilling budgets to reflect the changed
economics of exploration and production.  Thus, a drilling market which is
driven primarily by the exploration and production of only one of those
commodities will generally see a change in the demand for drilling services
triggered by the change in the price of the underlying commodity.  These
changes in demand for drilling services often occur quickly and can have
significant magnitude.  For example, the weak price of natural gas during most
of 1991 and early 1992 had a significant depressing effect on jack-up demand
during 1991 and early 1992.

         During the periods discussed herein, the Company operated primarily in
the U.S. Gulf of Mexico and the Bay of Campeche, offshore Mexico.  These
markets are further discussed below. The profitability of offshore drilling in
these markets, as well as most of the world's offshore drilling markets, has
been volatile since the mid-1980's and is expected to remain volatile until the
supply of jack-up rigs and demand therefor move closer to equilibrium levels.
The Company is unable to predict future oil and gas prices or future levels of
offshore drilling activity.

         The jack-up drilling market in the U.S. Gulf of Mexico is highly
competitive.  A significant number of offshore drilling companies have rigs in
this market and, as a result, no one contractor is able to materially affect
pricing levels.  Indeed, day rates can and have exhibited major changes on
relatively small changes in the rig supply and demand situation in this market.

         As illustrated in the preceding graphs, since 1992, demand for jack-up
rigs in this market has shown general improvement.  Day rates during this
period generally increased until late 1993, however, they began to decline
thereafter.  The decline in day rates during 1994 was due primarily to the
supply of marketed jack-up rigs growing faster than the rate of growth of
jack-up rig demand.  The "Marketed Rigs" graph illustrates the variance in the
growth in the supply of marketed rigs versus working rigs.  As noted on that
graph, during 1992, 1993 and 1994, the average utilization of marketed rigs was
approximately 71%, 90% and 81%, respectively.  The growth in the marketed
jack-up rig supply was due to two factors -- (i) net rig mobilizations into
this market and (ii) reactivations (primarily during 1993) of previously
noncompetitive rigs.

         In late 1994 and early 1995, the price of natural gas continued to
deteriorate due to a mild winter in the U.S.  As a result, jack-up rig demand
in the U.S. Gulf of Mexico has shown a significant decline since year-end 1994.
According to Offshore Data Services, as of February 28, 1995, there were 141
jack-up rigs in the U.S. Gulf of Mexico of which 90 were contracted (a 64%
utilization rate).  Day rates during early 1995 have also deteriorated and may
decline further.  Moreover, as previously discussed, jack-up rigs are mobile
and competitors could move additional rigs from other markets to the U.S. Gulf
of Mexico.  In addition, there are additional non-marketed rigs stacked in the
U.S. Gulf of Mexico which, subject to some expenditure, have been or could be
reactivated.  Such movement or reactivation could further depress pricing
levels.

         The Bay of Campeche drilling market experienced rapid growth in rig
demand during the period from late 1992 to mid-1993.  Since that time, the
market has shown general deterioration.  The Company was able to contract two
of its rigs (the MARINE 301 and MARINE 303) into this market in late 1992 and
another in mid-1993.  The first two rigs completed their contracts in late 1993
and early 1994, respectively, and subsequently returned to the U.S. Gulf of
Mexico.  The third rig (the MARINE 300) continues to operate in this market at
the present time pursuant to extensions of the initial contract.  The Company
currently expects that contract to expire in June 1995 and intends, if no
additional jobs are available in this market at that time, to mobilize that rig
to the U.S.  Gulf of Mexico or other international markets.

         All of the rigs in the Bay of Campeche are performing drilling
services for Petroleos Mexicanos ("Pemex"), the national oil company of the
Republic of Mexico.  Of the rigs working for Pemex in the Bay of Campeche, some
are subject to contracts between the respective drilling contractors and Pemex
and the other rigs are working for turnkey companies which, in turn, have
entered into turnkey drilling contracts with Pemex.  The MARINE 300 is
contracted to Industrial Perforadora, S.A. de CV ("IPC") which, in turn, is
supplying the rig and its services to Pemex pursuant to a contract between
Pemex and IPC.

         Recently, Mexico's currency, the peso, has suffered a significant
devaluation.  If this devaluation were to adversely affect Pemex's drilling
programs, the demand for jack-up rigs in this market could further deteriorate.
The Company is unable at this time to predict the effect of this occurrence on
the Company's operations.

(1)  Average of weekly data published by Offshore Data Services.

(2)  The numbers included in the table represent the average number of rigs
     (rounded to the nearest whole number) operated by the Company for the
     periods indicated.

(3)  From January 1 to March 12, 1990, the Company operated 16 rigs.  In March
     1990, the Company acquired four additional rigs and assumed charter
     agreements covering three additional rigs.  The Company's rig fleet was
     substantially reduced during 1991 and 1992.  See Item 2 "Properties -- Rig
     Fleet."

(4)  "Average day rate" is determined by dividing the total gross revenue
     earned by the Company's rigs during a given period by the total number of
     days that the Company's rigs were under contract during that period.

DRILLING OPERATIONS AND CUSTOMERS

         Most of the Company's drilling contracts provide for compensation on a
"daywork" basis.  Under daywork contracts, the Company receives a fixed amount
per day for providing drilling services using the rigs it operates.  The
Company does not market its rigs under fixed price or turnkey contracts.  In
recent years, the Company's rigs have generally been contracted on a
well-to-well basis due to highly competitive conditions.  In early 1993,
however, the Company obtained longer term contracts in Mexico, including two
multi-well contracts and a one-year contract with extensions.  To the extent
available, the Company will continue to focus upon obtaining, both foreign and
domestic, additional term contracts in the future.

         The Company provides drilling services to a customer base which
includes independent and major oil and gas companies. As is typical in the
industry, the Company does business with a relatively small number of customers
at any given time. The loss of any one of the Company's customers could, at
least on a short-term basis, have a material adverse effect on the Company's
profitability.  Management believes, however, that at current levels of
activity, the Company would have alternative customers for its services if it
lost any single customer and that the loss of any one customer would not have a
material adverse effect on the Company on a long-term basis. See Note 9 of
Consolidated Financial Statements included in this report for further
information regarding the Company's major customers. The Company's management
believes that its customer relationships are good.

ENVIRONMENTAL MATTERS

    General

         The Company is subject to numerous domestic and foreign governmental
regulations that relate directly or indirectly to its operations, including
certain regulations (i) controlling the discharge of materials into the
environment, (ii) requiring removal and cleanup under certain circumstances,
(iii) requiring the proper handling and disposal of waste materials, or (iv)
otherwise relating to the protection of the environment. For example, the
Company, as an operator of mobile offshore drilling rigs in waters of the
United States and certain offshore areas, may be liable for damages and for the
cost of removing oil spills for which it is held responsible, subject to
certain limitations.  Laws and regulations protecting the environment have
become more stringent in recent years and may, in certain circumstances, impose
"strict liability," rendering a company liable for environmental damage without
regard to negligence or fault on the part of such company.  Such laws and
regulations may expose the Company to liability for the conduct of or
conditions caused by others or for acts of the Company that were in compliance
with all applicable laws at the time such acts were performed.  The application
of these requirements or the adoption of new requirements could have a material
adverse effect on the Company.  The Company believes that it has conducted its
operations in substantial compliance with all applicable environmental laws and
regulations.

         The Company has generally been able to obtain contractual
indemnification in its drilling contracts against pollution and environmental
damages that are not caused by the gross negligence or willful misconduct of
the Company, but there can be no assurance that such indemnification will be
enforceable in all instances, that the customer will be financially able in all
cases to comply with its indemnity obligations, or that the Company will be
able to obtain such indemnification agreements in the future.

         The Company maintains insurance coverage against certain environmental
liabilities, but there can be no assurance that such insurance will continue to
be available or carried by the Company or, if available and carried, will be
adequate to cover the Company's liability in the event of a catastrophic
occurrence.

    U.S. Oil Pollution Act of 1990

         The U.S. Oil Pollution Act of 1990 ("OPA '90") and regulations
promulgated pursuant thereto impose a variety of regulations on "responsible
parties" related to the prevention of oil spills and liability for damages
resulting from such spills.  A "responsible party" includes the owner or
operator of a facility or vessel, or the lessee or permittee of the area in
which an offshore facility is located.  OPA '90 assigns liability to each
responsible party for oil removal costs and a variety of public and private
damages.  While liability limits apply in some circumstances, a responsible
party for an Outer Continental Shelf facility must pay all spill removal costs
incurred by a federal, state or local government.  OPA '90 establishes
liability limits (subject to indexing) for mobile offshore drilling rigs.  If
functioning as an offshore facility, the mobile offshore drilling rigs are
considered "tank vessels" for spills of oil on or above the water surface, with
liability limits of $1,200 per gross ton or $10,000,000.  To the extent damages
and removal costs exceed this amount, the mobile offshore drilling rigs will be
treated as an offshore facility and the offshore lessee will be responsible up
to higher liability limits of all removal costs plus $75,000,000.  A party
cannot take advantage of liability limits if the spill was caused by gross
negligence or willful misconduct or resulted from violation of a federal
safety,





                                       8
<PAGE>   11
construction, or operating regulation.  If the party fails to report a spill or
to cooperate fully in the cleanup, liability limits likewise do not apply.  Few
defenses exist to the liability imposed by OPA '90.

         OPA '90 also imposes ongoing requirements on a responsible party.
These include proof of financial responsibility (to cover at least some costs
in a potential spill), and preparation of an oil spill contingency plan.  A
failure to comply with ongoing requirements or inadequate cooperation in a
spill event may subject a responsible party to civil or criminal enforcement
action.  In short, OPA '90 places a burden on drilling rig owners or operators
to conduct safe operations and take other measures to prevent oil spills.  If a
spill occurs, OPA '90 then imposes liability for resulting damages.

    Outer Continental Shelf Lands Act (U.S.)

         The Outer Continental Shelf Lands Act authorizes regulations relating
to safety and environmental protection applicable to lessees and permittees
operating on the Outer Continental Shelf.  Specific design and operational
standards may apply to Outer Continental Shelf vessels, rigs, platforms,
vehicles and structures.  Violations of lease terms relating to environmental
matters or regulations issued pursuant to the Outer Continental Shelf Lands Act
can result in substantial civil and criminal penalties as well as potential
court injunctions curtailing operations and the cancellation of leases.  Such
enforcement liabilities can result from either governmental or citizen
prosecution.

    CERCLA and RCRA (U.S.)

         The Comprehensive Environmental Response, Compensation, and Liability
Act of 1980 ("CERCLA"), as amended, currently exempts crude oil, and the
Resource Conservation and Recovery Act ("RCRA"), as amended, currently exempts
certain drilling materials, such as drilling fluids and produced water, from
the definitions of hazardous substances and hazardous wastes for purposes of
these statutes.  The Company's operations, however, may involve the use or
handling of other material that may be classified as environmentally hazardous
substances or wastes.  There can be no assurances that these exemptions will be
preserved in future amendments of such acts, if any, or that more stringent
federal or state laws and regulations protecting the environment will not be
adopted.  CERCLA assigns strict liability to each responsible party for all
response and remediation costs, as well as natural resource damage.  Few
defenses exist to the liability imposed by CERCLA.

GOVERNMENTAL REGULATION

         The Company's business is affected by political developments and by
federal, state, foreign and local laws and regulations that relate directly to
the oil and gas industry.  The adoption of laws and regulations curtailing
exploration and developmental drilling for oil and gas for economic,
environmental or other policy reasons would and have adversely affected the
operations of the Company by limiting available drilling opportunities for its
customers and/or increasing the costs of such activities to the Company or its
customers.  The Company believes that it has conducted its operations in
substantial compliance with applicable governmental laws and regulations.

OPERATIONAL RISKS AND INSURANCE

         Contract drilling operations are subject to various risks including
blowouts, cratering, fires and explosions, each of which could result in damage
to or destruction of drilling rigs and oil and gas wells, damage to life and
property, suspension of operations, and environmental damage through oil
spillage and extensive uncontrolled fires.  The Company insures its drilling
rigs and plant assets for amounts approximating used equipment replacement cost
and also insures against catastrophic losses resulting from employer's
liability and other risks customary in the energy service industry.  The
Company currently maintains insurance coverage it believes to be customary in
the industry against certain general and marine public liabilities, including
liabilities for personal injuries.  Except in limited circumstances, this
insurance does not cover liability for pollution or environmental damage that
originates below the water surface, although the Company is





                                       9
<PAGE>   12
generally indemnified against such pollution and environmental liabilities by
its customers.  There is no assurance that such insurance or indemnification
will be adequate to protect the Company against liability from all consequences
of well disasters, extensive fire damage or damage to the environment.
Recognizing these risks, the Company has programs that are designed to promote
a safe environment for its personnel and equipment.

EMPLOYEES

         As of March 6, 1995, the Company had approximately 670 employees.  The
number of employees varies throughout the year depending on the level of
drilling activity.  The Company considers relations with its employees to be
good.  None of the Company's employees is presently represented by labor
unions.

ITEM 2.  PROPERTIES

RIG FLEET

         All of the Company's rigs are jack-up rigs, which are mobile
self-elevating drilling platforms equipped with legs that can be lowered to the
ocean floor until a foundation is established to support the drilling platform.
The Company owns and operates thirteen rigs, nine of which are mat supported
rigs (i.e., they have a lower hull attached to the rig legs) and four are of
independent leg design.  Five of the mat supported rigs and one of the
independent leg rigs are slot type jack-up units which are configured for the
drilling operations to take place through a slot in the hull.  The Company's
other four mat supported rigs and three of the independent leg rigs have a
cantilever feature which allows the extension of the drilling equipment over a
customer's platform to perform development drilling or workover operations.
The Company's rigs are currently capable of drilling to depths of 20,000 to
30,000 feet in maximum water depths ranging from 200 to 300 feet.  Three of the
Company's rigs are presently configured to work in international markets
outside the U.S. Gulf of Mexico.  The Company's other rigs could, if applicable
modifications were made and certifications obtained, operate in certain
non-hostile areas outside of their current markets.  The Company believes that
all of its rigs are in good operating condition and have been well maintained.

[PICTURE]

Mat Supported Rig -- This type of rig consists of a floating upper hull with
three legs which are attached to a lower hull commonly referred to as a mat.
After being towed to the drilling location, the legs are lowered until the mat
contacts the seabed and the upper hull is jacked to the desired elevation above
sea level.  One advantage of mat supported rigs is the ability to operate in
areas having soft seabed conditions where independent leg rigs are prone to
have excessive penetration and subject to leg damage.





Independent Leg Rig -- This type of rig consists of a floating  hull with three
independent elevated legs.  After being towed to the drilling location, the legs
are lowered until they penetrate the seabed and the hull is jacked to the
desired elevation above sea level.

     The Company's fleet was substantially reduced in 1991 and 1992, during
which the Company reduced the number of rigs from twenty-one to eleven.  See
Item 7 " -- The Recapitalization."  In August 1993, the Company acquired and
refurbished the MARINE 304.  Later in 1993, the Company refurbished and
reactivated the MARINE 225 (previously named the MARINE 1).  During the fourth
quarter of 1994, the Company acquired the MARINE 3 (which the Company had
chartered from its former owner since early 1993) for approximately $5,500,000.
In addition, the Company acquired the MARINE 201 in December 1994 for
approximately $7,000,000.

OTHER PROPERTY

         The Company leases approximately 28,000 square feet of office space in
Sugar Land, Texas for its headquarters.  Due to the pending expiration of this
lease in May 1995, the Company has leased approximately 19,000 square feet in
an office building in Sugar Land and plans to move thereto in April 1995.  In
addition, the Company leases a warehouse, storage and repair facility,
including approximately 31 acres of land and 60,000 square feet of buildings,
in Rosharon, Texas (near Houston).

         ITEM 3. LEGAL PROCEEDINGS

GENERAL

         Various claims have been filed against the Company and its
subsidiaries in the ordinary course of business, particularly claims alleging
personal injuries.  Management believes that the Company has established
adequate reserves for any liabilities which may reasonably be expected to
result from these claims.  In the opinion of management, no pending claims,
actions or proceedings against the Company or its subsidiaries are expected to
have a material adverse effect on its financial position or results of
operations.

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

FINANCIAL CONDITION -- GENERAL

         The following is a discussion of the Company's financial condition,
results of operations, historical financial resources and working capital.
This discussion and analysis should be read in conjunction with the Company's
Consolidated Financial Statements and Notes thereto included in Item 8 of this
report.

    Overview

         During most of 1992, demand for drilling services in the U.S. Gulf of
Mexico was generally depressed due primarily to the uncertainty and occasional
volatility of oil and gas prices, as well as an oversupply of jack-up drilling
rigs.  During the latter part of 1992, the demand for drilling services in the
U.S. Gulf of Mexico improved markedly from earlier levels, which, combined with
a continued decline in the supply of jack-up rigs, resulted in generally higher
jack-up rig utilization and day rates.  The Company attributes this improvement
in demand primarily to the increase in the price of domestic natural gas during
that period.  Market conditions continued to improve during early 1993 due
primarily to increased drilling activity in the Bay of Campeche by Pemex.  This
increased drilling activity further reduced the supply of jack-up rigs in the
U.S. Gulf of Mexico.  In addition, demand for jack-up rigs in the U.S. Gulf of
Mexico showed general improvement throughout 1993.  During 1994, oil prices
showed general improvement from the levels experienced in late 1993; gas
prices, however, experienced a general decline during the last three quarters.
In 1994, demand for offshore drilling services worldwide was generally lower
than in 1993 due to the prices of these commodities.  Jack-up rig demand in the
U.S. Gulf of Mexico was somewhat stronger in 1994 compared to 1993, but jack-up
rig demand in the Bay of Campeche was generally weaker.  Both markets, however,
had an excess supply of rigs available for work in 1994.

    The Company

         Prior to 1993, the Company derived most of its revenues from contract
drilling in the U.S. Gulf of Mexico.  During 1993, the Company operated two to
three rigs in the Bay of Campeche and received a significant amount of revenues
therefrom.  During 1994, the Company had one rig operating in this market.  See
Note 9 to the Company's Consolidated Financial Statements included in Item 8 of
this report.

         During 1992 and the first quarter of 1993, the Company completed a
series of related transactions that provided for the Recapitalization.  See "
- -- The Recapitalization" below.  Primarily as a result of the Recapitalization,
between January 1, 1992 and early 1993, the Company eliminated its preferred
stock obligations of approximately $64,000,000 and its indebtedness of
approximately $148,000,000.  The Company's rig fleet was also reduced during
that period from 21 rigs to 11 rigs.

         The Company's financial results improved markedly during the fourth
quarter of 1992 and throughout 1993 due to the improvements in business
conditions noted above and the effects of the Recapitalization.

         The Company's results in 1994 reflected the impact of increased
competition in the U.S. Gulf of Mexico and reduced activity levels in Mexico's
Bay of Campeche.  Increased competition in the U.S. Gulf of Mexico was due to
(i) an influx of jack-up rigs into that market from other markets, (ii) an
increased supply of marketed rigs due to reactivations of previously
noncompetitive rigs and (iii) lower than expected growth in jack-up demand due
to generally lower natural gas prices.  Even though demand for jack-ups in the
U.S. Gulf of Mexico grew by approximately 14% (1994 vs. 1993), the supply of
marketed jack-ups grew by 26% during that period.  The effects of this
increased competition in that market included generally lower utilization and
day rates experienced by the Company and most of the other competitors in this
market.

         THE RECAPITALIZATION

         The Recapitalization of the Company in 1992 and the first quarter of
1993 included several transactions which significantly reduced the Company's
debt and eliminated its preferred stock obligations.  The table presented below
reflects certain effects of the Recapitalization transactions and other
payments of debt as if each of the transactions had been consummated on January
1, 1992.  The capitalized terms used in the table are defined in the narrative
following the table which further describes each of the Recapitalization
transactions.

    Background

         In June 1992, the Company entered into an agreement (the
"Recapitalization Agreement") with certain of its lenders, including The Chase
Manhattan Bank, N.A. ("Chase"), and certain preferred shareholders, including
Warburg, Pincus Capital Company, L.P. ("Warburg"), Aeneas Venture Corporation
("Aeneas"), Capricorn Investors, L.P. ("Capricorn," and together with Warburg
and Aeneas, the "Marine Investors") and William O. Keyes ("Mr. Keyes").  At the
time the Company entered into the Recapitalization Agreement, a substantial
portion of its debt was in default.  The Company had unsuccessfully sought a
business combination during the prior year and was close to exhausting its cash
reserves.  The Recapitalization collectively consisted of the following
described transactions, substantially all of which were contemplated by the
Recapitalization Agreement.





                                       17

    Bridge Loan and Bank One Transaction

         Concurrently with the execution of the Recapitalization Agreement, the
Company entered into a $4,000,000 bridge loan agreement with the Marine
Investors (the "Bridge Loan") to provide sufficient funding to enable the
Company to complete the Recapitalization.  The Company also then purchased
approximately $13,942,000 of indebtedness (approximately $12,901,000 principal
plus accrued interest) owed by one of its subsidiaries for $500,000 (the "Bank
One Transaction").

    Marine 200 Restructuring

         On July 14, 1992, a subsidiary of the Company owning a single jack-up
rig filed for protection under Chapter 11 of the United States Bankruptcy Code
in order to restructure certain indebtedness held by MarAd, an agency of the
U.S. Department of Transportation.  On March 11, 1993, the creditors of this
subsidiary unanimously approved its plan of reorganization and on March 16,
1993 the plan was confirmed by the bankruptcy court.  Under the plan (the
"Marine 200 Restructuring"), the subsidiary's outstanding indebtedness to MarAd
of approximately $10,554,000 was reduced by approximately $7,471,000 to
approximately $3,083,000, which was fully retired later in 1993.

  Chemical Bank Restructuring, First City Redemption and Chemical Bank Extension

         In August 1992, the Company agreed to a restructuring (the "Chemical
Bank Restructuring") of indebtedness owed to Chemical Bank and First City --
Texas, Houston N.A. ("First City"), which was in default and which aggregated
approximately $22,533,000 as of the date of the restructuring.  The Chemical
Bank Restructuring extended the maturity of approximately $18,400,000 of such
indebtedness to April 30, 1993 and provided for payment of the balance
(approximately $4,070,000) during 1992.  In January 1993, the Company acquired
all of such indebtedness then held by the successor to First City,
approximately $4,215,000 (approximately $4,205,000 principal plus accrued
interest), at a five percent discount (the "First City Redemption").  Later in
1993, the Company retired the remaining indebtedness owed to Chemical Bank.

    Storm Drilling Restructuring

         In September 1992, the Company effectively discharged approximately
$52,106,000 (approximately $47,841,000 principal plus accrued interest, net of
deferred financing costs) of indebtedness owed to MarAd by a subsidiary of the
Company (the "Storm Drilling Restructuring") in consideration for the transfer
to entities designated by MarAd of the seven jack-up rigs that secured such
debt and the transfer to MarAd of an interest in certain then pending
litigation against the manufacturer of one of the Company's jack-up rigs (the
"Marine 7 Litigation").  As a result of the settlement of the Marine 7
Litigation in early 1993, MarAd received approximately $3,802,000.

    Preferred Stock Reclassification, Chase Exchange and Bridge Loan Exchange

         On October 29, 1992, immediately following the meeting of the
Company's shareholders at which certain elements of the Recapitalization were
approved, the Company (i) effected the Reverse Stock Split which reclassified
the then outstanding 18,838,643 shares of Common Stock (pre Reverse Stock
Split) into 753,546 shares of Common Stock, (ii) reclassified all outstanding
shares of the Company's 14% nonconvertible redeemable preferred stock (the "Old
Preferred Stock") into an aggregate of 19,369,893 shares of Common Stock (the
"Preferred Stock Reclassification"), (iii) issued 4,994,752 shares of Common
Stock in exchange for approximately $51,919,000 (approximately $46,801,000
principal plus accrued interest, net of deferred financing costs) of
indebtedness of a subsidiary of the Company held primarily by Chase (the "Chase
Exchange"), (iv) issued 3,270,054 shares of Common Stock to the Marine
Investors in exchange for the approximately $4,087,000 ($4,000,000 principal
plus accrued interest) outstanding under the Bridge Loan (the "Bridge Loan
Exchange"), (v) paid contingent dividend rights (the "Litigation Dividend
Rights") to the holders of record of Common Stock immediately prior to the
consummation of the





                                       18
<PAGE>   21
other Recapitalization transactions occurring on such date, and (vi) entered
into a Registration Rights Agreement and a Shareholders' Agreement with the
Marine Investors, Chase, Mr. Keyes and certain other participants in the
Recapitalization.

         The Litigation Dividend Rights provided for a payment to be made if
the net litigation proceeds from the Marine 7 Litigation exceeded certain
threshold amounts.  As a result of the settlement of this litigation in January
1993, no amounts have been or will be paid pursuant to the Litigation Dividend
Rights.

    Rights Offering

         In December 1992, the Company concluded a rights offering (the "Rights
Offering") in which it sold 9,638,214 shares of Common Stock, at $1.25 per
share, out of a maximum offering of 12,810,277 shares.  The transferable rights
had been distributed to the holders of record of the Common Stock immediately
prior to the consummation of the Recapitalization transactions effected on
October 29, 1992.  Pursuant to the Recapitalization Agreement, the Marine
Investors purchased 4,800,000 shares of Common Stock in the Rights Offering.

    Quasi-Reorganization

         As of December 31, 1992, the Company adopted quasi-reorganization
accounting procedures which allowed the Company to eliminate its accumulated
deficit against paid-in capital and to revalue its assets and liabilities to
estimated fair values.

FINANCIAL CONDITION - LIQUIDITY AND CAPITAL RESOURCES

    Historical Information

         The Company had positive working capital at December 31, 1994 of
$48,413,000 as compared to working capital of $32,089,000 at December 31, 1993.
The change in working capital was due primarily to borrowings under a credit
facility and cash generated by operations, net of capital expenditures.

         Net cash provided by operating activities was $14,858,000 in 1994 and
$23,493,000 in 1993 as compared to net cash used in operations of $6,254,000
during 1992.  Non-cash items included in the Company's Statement of Cash Flows
in 1992 consist of extraordinary gains on debt extinguishment of $104,523,000
and writedowns of rigs of $68,320,000.

         Cash provided by or (used in) investing activities was $(32,968,000),
$(17,772,000) and $677,000 during 1994, 1993 and 1992, respectively.  Cash used
in investing activities reflected the net impact of the following transactions
- -- (i) purchases of short-term investments of $29,537,000, (ii) proceeds of
$11,400,000 received from maturing short-term investments and (iii) capital
expenditures of $15,385,000.  Capital expenditures in 1994 consisted primarily
of two offshore drilling rig purchases in the fourth quarter, the MARINE 3 for
$5,500,000 and the MARINE 201 (formerly the Nordic Explorer) for $6,900,000.
Other major expenditures included $1,800,000 for the purchase of top drive
drilling systems and other rig upgrades and drill pipe purchases of
approximately $1,000,000.  Cash used in 1993 consisted primarily of capital
expenditures of $18,329,000, with the largest expenditures being the
acquisition and refurbishment of the MARINE 304 (formerly Key Largo) in August
1993, consisting of acquisition costs of $9,950,000 and refurbishment costs of
$2,400,000.  In addition in 1993, the MARINE 225 was reactivated and
refurbished at a cost of $3,900,000 and the MARINE 303 was upgraded at a cost
of $1,200,000.  The balance of $879,000 was used primarily for drill pipe and
other purchases.  Cash provided from investing activities in 1992 was generated
primarily from proceeds from sales of two rigs.





                                       19
<PAGE>   22
         Cash provided by financing activities was $15,013,000, $6,825,000, and
$10,247,000 during 1994, 1993 and 1992, respectively.  Cash provided by
financing activities in 1994 consisted primarily of borrowings from a credit
facility to purchase two drilling rigs and to partially upgrade other rigs.
Cash provided by financing activities in 1993 consisted of the sale of Common
Stock which was partially offset by the payments of debt discussed below.
During 1992, the Company (i) received $4,000,000 from the Bridge Loan in
connection with the Recapitalization, (ii) received net proceeds of $11,537,000
from the Rights Offering, and (iii) made debt payments of $12,277,000.

         In connection with the Recapitalization, in November and December 1992
the Company sold stock pursuant to the Rights Offering.  Approximately
9,638,000 shares of Common Stock were purchased for gross proceeds of
approximately $12,048,000.  Approximately $186,000 of broker solicitation fees
were paid on approximately 3,055,000 shares and approximately $325,000 of
expenses were incurred in connection with the Rights Offering.

         In early July 1993, the Company completed a sale of 5,000,000 shares
of Common Stock which provided net proceeds of approximately $28,200,000.  The
proceeds of the offering were used for (i) the reduction of bank indebtedness
during the third quarter as discussed in the following paragraph, (ii) the
reactivation and refurbishment of the MARINE 225, (iii) the purchase and
refurbishment of the MARINE 304 and (iv) the balance was dedicated for general
corporate purposes, including possible acquisitions of offshore drilling rigs.
Approximately $422,000 of expenses were incurred in connection with the
offering.

         On December 31, 1992, the Company's indebtedness was $21,280,000, with
shareholders' equity of $60,695,000.  During the first quarter of 1993, the
Company reduced its debt pursuant to a redemption and retirement of $4,205,000
of indebtedness at 95% of face value followed by additional debt retirements of
$4,184,000.  During the third quarter of 1993, the Company retired its
remaining indebtedness of $10,274,000.  As a result of debt retirements, the
sale of Common Stock and improved cash flows from operations, the Company had
no debt and had shareholders' equity of $106,417,000 as of December 31, 1993.
On December 31, 1994, the Company's indebtedness was $15,000,000 with
shareholders' equity of $112,731,000.

    Outlook

         In late 1994, the Company commenced a program (the "Rig Upgrade
Program") to upgrade the operational capabilities of ten of its rigs during the
next two years at an aggregate cost of approximately $30,000,000.  This program
includes the following upgrades: (i) converting the power systems of seven
mechanically powered rigs, (ii) adding top drive drilling systems to the
Company's seven mechanically powered rigs, (iii) adding a top drive drilling
system to the MARINE 303, (iv) increasing the water depth rating and adding a
cantilever feature to the MARINE 304 and (v) increasing the water depth rating
of the MARINE 300.  At the present time, the Company has committed and/or
expended approximately $7,700,000 in connection with this program.  During
these projects, the affected rigs will be taken out of service in order to
complete the modifications.  At the present time, the Company anticipates that
most of the projects will involve approximately two to three weeks of downtime
per affected rig except for the MARINE 304 which could require up to four
months downtime.  The MARINE 304 modifications, however, could be split into
two or three phases, each of which could be separately completed.  The Company
may elect to complete these modifications in this manner in order to maximize
its working capital and optimize rig downtime.  The Company's profitability
could be reduced during these periods due to lost revenues.  Future
expenditures for the Rig Upgrade Program will be subject to the Company's
outlook for drilling market conditions, as well as changes in the Company's
financial condition.  Accordingly, the Company may elect to defer or cancel
substantial portions of this program.





                                       20
<PAGE>   23
         The Company continues to pursue the acquisition of additional drilling
rigs to enhance its fleet.  As of the date of this report, the Company has no
planned or pending rig acquisitions.  Future acquisitions, if any, would likely
be funded from the Company's working capital resources, or through debt and/or
equity financing.  The Company cannot predict whether it would be successful in
acquiring additional rigs, and obtaining financing therefor, on acceptable
terms.  Depending upon the Company's success in acquiring rigs in the future,
as well as future industry conditions, the Company may elect to defer or
suspend portions of the Rig Upgrade Program discussed in the preceding
paragraph in order to preserve its working capital resources.

         As of the date of this report, the Company estimates its 1995 capital
expenditures to be as follows:

         *       Planned expenditures include committed amounts and are subject
                 to adjustment based upon industry conditions as described
                 herein.

         Additional expenditures related to the Rig Upgrade Program, to the
extent completed, would be disbursed subsequent to 1995.

         On December 1, 1994, Keyes Holding Corporation ("KHC"), a wholly-owned
subsidiary of the Company, entered into a revolving/term loan agreement (the
"Loan") with a U.S. financial institution for $35,000,000.  That agreement
includes an eighteen- month revolving credit facility which is convertible at
the end of that period into a three-year term loan facility.  The term loan is
amortized monthly at the rate of 20% of the initial term loan amount per year
with a balloon payment for the remaining principal (40% of the initial term
loan amount) due at the maturity of the term loan.  As of December 31, 1994,
the related debt outstanding was $15,000,000 and the amount of unused line of
credit subject to the Loan was $20,000,000.  Loan proceeds may be used to
purchase additional jack-up drilling rigs or to make capital improvements to
the Company's existing drilling rig fleet.  The Company guarantees up to
$8,750,000 of the borrowings under the loan agreement.  On February 28, 1995,
the Company repaid $5,000,000 of the revolving credit facility associated with
the Loan.  The Company anticipates that it will re-borrow this amount in
addition to other borrowings in 1995 to fund capital expenditures.  See Note 5
to the Consolidated Financial Statements included in Item 8 of this report.

         Recent substantial weakness in the U.S. Gulf of Mexico drilling market
has adversely affected the Company's operations and cash flow.  As a result,
the Company has elected to suspend the marketing of certain rigs.  These rigs
will generally be deactivated in a common offshore location and, after
preparation for extended idle time, will be maintained periodically by a small
maintenance crew.  The Company believes that these actions will benefit cash
flow and working capital during periods of depressed market conditions.  The
Company anticipates that additional rigs could be deactivated if industry
conditions remain depressed.  The remaining rigs will be aggressively marketed
to maximize cash flow.  In addition to the foregoing, the Company will continue
to aggressively control and/or reduce its cost structure.

         Recently, Mexico's currency, the peso, has suffered a significant
devaluation.  If this devaluation were to adversely affect Pemex's drilling
programs, the Company's business could be adversely impacted.  The Company is
unable to predict at this time the effect of this occurrence on the Company's
operations.





                                       21
<PAGE>   24
         On March 7, 1995, the Company announced that its Board of Directors
had authorized the repurchase of up to 4,000,000 shares of the Company's Common
Stock.  The action reflects the Company's view that its remaining shareholders
will benefit from such repurchases.  The repurchases may be effected, from time
to time, in accordance with applicable securities laws, through solicited or
unsolicited transactions in the market or in privately negotiated transactions.
No limit was placed on the duration of the repurchase program.  Subject to
applicable securities laws, such repurchases shall be at such time and in such
amounts as the Company deems appropriate.  The Company will fund such
repurchases from working capital.

         The Company believes that its projected cash flows and current working
capital resources are sufficient to meet its working capital, debt service,
Common Stock repurchase program and capital expenditure requirements for the
foreseeable future.

         On November 2, 1994, the Company and Falcon Drilling Company, Inc.
("Falcon") signed a letter of intent to merge.  On February 15, 1995, Falcon
and the Company agreed to terminate the letter of intent and related
discussions because then current market conditions led both parties to conclude
that a definitive agreement could not be reached at that time.  From time to
time, the Company has had discussions, and anticipates that such discussions
will continue in the future, with other parties regarding rig acquisitions and
business combinations.  The Company cannot predict the outcome of such
discussions.

Income Taxes

         In February 1992, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes".  Statement 109 required a change from the deferred method of accounting
for income taxes of APB Opinion 11 to the asset and liability method of
accounting for income taxes.  Under the asset and liability method of Statement
109, deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases.  Deferred tax assets and liabilities are measured using enacted tax
rates expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled.  Under Statement 109, the
effect on deferred tax assets and liabilities of a change in tax rates is
recognized in income in the period that includes the enactment date.

         Effective December 31, 1992, in conjunction with the adoption of
quasi-reorganization accounting, the Company adopted Statement 109.  The change
in the method of accounting for income taxes had no cumulative effect on the
1992 consolidated statement of operations.

    Federal Income Tax Effects of the Recapitalization

         The Company has taken the position that the Recapitalization and the
Rights Offering did not cause an ownership change under Section 382 of the
Internal Revenue Code of 1986, as amended, (the "Code") based on the
applicability of Section 382(l)(3)(C) and Regulation Section
1.382-2T(h)(4)(i)(B).  Since neither the Internal Revenue Service nor the
Department of Treasury has established any rules or guidance on Section
382(l)(3)(C), there can be no assurance that an ownership change will not be
deemed to have occurred.  If an ownership change were deemed to have occurred,
the utilization of the Company's net operating losses and investment tax credit
carryforwards, would be substantially limited.

         In addition, the Recapitalization and certain transactions related
thereto have resulted in substantial reductions of the Company's tax net
operating loss carryforwards.  Moreover, if the Company fails to prevail on
certain of the tax positions it has taken with respect to the tax effects of
those transactions, the Company's net operating loss carryforwards could be
further reduced in a substantial manner.  Appropriate valuation allowances for
deferred tax assets have been established in the consolidated financial
statements based on management's consideration of whether it is more likely
than not that some portion or all of the net operating losses and investment
tax credit carryforwards will not be realized.





                                       22
<PAGE>   25
         Sales of significant numbers of shares of Common Stock by the Company
or certain significant shareholders of the Company could result in an ownership
change under Section 382 of the Code.  An ownership change under Section 382 of
the Code would limit the Company's ability to use its remaining net operating
losses against its future income in each taxable year to no more than an amount
equal to the product of the fair market value of the Company's equity
immediately prior to such an ownership change multiplied by the long-term
federal exempt rate then in effect.  Such an ownership change would also limit
the Company's ability to use its investment tax credit and general business
credit carryforwards for federal income tax purposes.

         For further discussion of the federal income tax effects of the
Recapitalization, see Note 6 to the Company's Consolidated Financial Statements
included in Item 8 of this report.

RESULTS OF OPERATIONS -- 1994 COMPARED WITH 1993

    Revenues

         During 1994, the Company generated drilling revenues of $70,597,000
which represented a decrease of $12,401,000 or 15% compared to 1993 drilling
revenues of $82,998,000.  The change in revenues reflected the net effect of
the following factors:  (i) an increase in the number of marketed rigs from 10
during the 1993 period to 11 rigs during 1994; (ii) a decrease in utilization
of marketed rigs from 97% during the 1993 period to 87% during 1994; and (iii)
a 14% decrease in average day rates from $23,019 during the 1993 period to
$19,686 in 1994.  The  decreases in utilization and average day rates resulted
principally from increased competition in the U.S. Gulf of Mexico and reduced
activity levels in Mexico's Bay of Campeche.  Revenues from the Bay of Campeche
market accounted for 10% ($7,306,000) and  28% ($23,459,000) of the Company's
revenues in 1994 and 1993, respectively, and 34% ($2,698,000) and 37%
($8,538,000) of the Company's operating income for 1994 and 1993, respectively.
If Pemex further reduces the level of its drilling activities, the Company's
operations could be adversely affected.

    Costs and Expenses

         Contract drilling expenses of $50,575,000 in 1994 represented an
increase of $5,245,000 or 12% compared to contract drilling expenses of
$45,330,000 in 1993.  This increase was primarily the result of  the addition
of two rigs to the Company's active fleet in late 1993 and through most of
1994.  The MARINE 225 (formerly the MARINE 1) was refurbished and operated from
October 1993 to May 1994 and again in November and December 1994.  The MARINE
304 was purchased, refurbished and activated in late 1993.

         Depreciation and amortization expense increased $2,421,000 or 46% from
$5,312,000 in 1993 to $7,733,000 in 1994.  The increase was primarily due to
the MARINE 304 and the MARINE 225 having a full year of depreciation in 1994
and, to a lesser extent, the MARINE 303 upgrade and the MARINE 3 acquisition in
November 1994.

         General and administrative expenses in 1994 decreased $4,623,000 or
51% from $8,999,000 in 1993 to $4,376,000 compared to 1994.  General and
administrative expenses were higher in 1993 primarily as a result of executive
bonuses of $4,436,000 paid pursuant to bonus agreements which were based upon
the price of the Company's stock in November 1993.  Excluding these bonuses,
general and administrative expenses were $4,376,000 and $4,563,000 during 1994
and 1993, respectively.  Excluding these bonuses, 1994's general and
administrative expenses decreased 4% or $187,000 as compared to 1993.

    Interest Expense

         Interest expense decreased $510,000 or 88% from $580,000 in 1993 to
$70,000 in 1994.  The decrease was related primarily to decreased debt as a
result of the Recapitalization.

    Interest Income

         Interest income increased $832,000 or 161% from $518,000 in 1993 to
$1,350,000 in 1994.  The increase was related primarily to increased cash
balances during 1994, as well as higher interest rates on short-term
investments.

    Income Taxes

         Income taxes of $3,193,000 for the year ended December 31, 1994,
consisted of current state and federal income taxes of $154,000, tax benefits
related to Common Stock issued pursuant to the Marine Drilling 1992 Long Term
Incentive Plan of $50,000 and deferred federal income taxes of $2,989,000.

RESULTS OF OPERATIONS -- 1993 COMPARED WITH 1992

    Revenues

         During 1993, the Company generated drilling revenues of $82,998,000
which represented an increase of $51,377,000 or 162% compared to 1992 drilling
revenues of $31,621,000.  The increases in revenues resulted primarily from the
following factors:  (i) an increase in the number of marketed rigs from 8
during the 1992 period to 10 rigs during 1993; (ii) an increase in utilization
of marketed rigs from 73% during the 1992 period to 97% during 1993; and (iii)
a 67% increase in average day rates from $13,816 during the 1992 period to
$23,019 in 1993.  The  increases in utilization and average day rates resulted
principally from increased drilling activity in the U.S. Gulf of Mexico and the
Bay of Campeche.  Revenues from the Bay of Campeche market accounted for 28%
($23,459,000) of the Company's revenues and 37% ($8,538,000) of the Company's
operating income for 1993.  The Company had no rigs in this market during 1992.

    Costs and Expenses

         Contract drilling expenses of $45,330,000 in 1993 represented an
increase of $16,141,000 or 55% compared to contract drilling expenses of
$29,189,000 in 1992.  This increase was primarily the result of increased rig
utilization in 1993.

         Depreciation and amortization expense in 1993 decreased $7,003,000 or
57% from $12,315,000 to $5,312,000 compared to 1992.  The decrease was
primarily due to the effect of the adoption of quasi-reorganization accounting
procedures on December 31, 1992 which resulted in a decrease in the carrying
value of property and equipment of $56,051,000.

         General and administrative expenses in 1993 increased $2,096,000 or
30% from $6,903,000 to $8,999,000 compared to 1992.  General and administrative
expenses increased primarily as a result of executive bonuses of $4,436,000
paid pursuant to bonus agreements which were based upon the price of the
Company's stock in November 1993 and a reversal of compensation expense
($741,000) related to expired options in 1992.  Excluding these items, general
and administrative expenses were $4,563,000 and $7,644,000 during 1993 and
1992, respectively.

     Interest Expense

         Interest expense decreased $9,147,000 or 94% from $9,727,000 in 1992
to $580,000 in 1993.  The decrease was related primarily to decreased debt as a
result of the Recapitalization and lower interest rates.

    Interest Income

         Interest income increased $419,000 or 423% from $99,000 in 1992 to
$518,000 in 1993.  The increase was primarily the result of larger cash
balances available for investment which was partially offset by lower interest
rates.

    Income Taxes

         Income taxes of $8,278,000 for the year ended December 31, 1993,
consisted of current foreign, federal and state income taxes of $800,000,
deferred federal income taxes of $5,376,000, the realization of
pre-quasi-reorganization net operating loss carryforwards of $1,612,000 and tax
benefits of $490,000 related to Common Stock issued pursuant to the Marine
Drilling 1992 Long Term Incentive Plan.  The latter amount was recorded to
shareholders' equity, while taxes currently payable represent federal
alternative minimum tax of $408,000, state income taxes of $12,000 and foreign
income taxes of $380,000.  As a result of the Recapitalization, the realization
of pre-quasi-reorganization net operating loss carryforwards of $1,612,000 were
charged directly to shareholders' equity.

(1)      BASIS OF PRESENTATION AND RECAPITALIZATION TRANSACTIONS

    Basis of Presentation

         References herein to the "Company" refer to Marine Drilling Companies,
Inc. ("Parent") and its wholly-owned subsidiaries, Marine Drilling Management
Company ("MDMC"), Keyes Holding Corporation ("KHC") and Marine Drilling
International, Inc. unless the context otherwise requires a reference only to
the Parent.

    Recapitalization Transactions

         On June 19, 1992, the Company entered into an agreement with certain
of its lenders and preferred shareholders providing for a significant
recapitalization ("Recapitalization").  On June 19, 1992, $500 was paid to one
of the lenders in exchange for the discharge of approximately $13,942 of bank
indebtedness.  On October 29, 1992, the Recapitalization was approved by the
Company's shareholders and, as a result, the Company's debt (including
interest) and preferred stock obligations were reduced during 1992 by
approximately $187,000 and the Company's rig fleet was substantially reduced.
The Recapitalization included a one-for-twenty-five reverse split of the
Company's $.10 par value common stock into $.01 par value common stock ("Common
Stock").

         In connection with the approval of the Recapitalization, the Company's
remaining bank indebtedness and related interest totalling approximately
$51,919 as of September 30, 1992 was completely discharged for approximately
5,000,000 shares of Common Stock which were issued to a group of the Company's
lenders.  The Recapitalization also included the reclassification of the
Company's 14% cumulative exchangeable preferred stock, par value $1.00 per
share ("Old Preferred Stock") with a liquidation preference as of October 29,
1992 of approximately $65,582 into 19,369,893 shares of Common Stock.

         The Company sold 9,638,214 shares of Common Stock of which 4,800,000
shares were purchased by three of the Company's principal shareholders pursuant
to a rights offering ("Rights Offering").  The Rights Offering was closed in
December 1992 with the Company receiving net proceeds of approximately $11,537.

         As part of the Recapitalization, the Company entered into a $4,000
bridge loan facility with three of its principal shareholders which was
intended to fund the Company's operations through the completion thereof.  On
October 29, 1992, the $4,000 principal amount and interest thereon were
exchanged for shares of Common Stock at an exchange price of $1.25 per share.

         During 1992 the Company defaulted on all series of its U.S. Government
guaranteed Title XI ("Title XI") ship financing bonds owed by two of its
subsidiaries.  The Company transferred custody and financial responsibility for
seven of its eight Title XI financed rigs to the Maritime Administration of the
United States Department of Transportation ("MarAd"), agreed to pay to MarAd
certain additional amounts in connection with certain litigation (see below),
proposed to restructure approximately $2,300 in debt and pay approximately $460
in consideration for the discharge of approximately $63,019 in debt and related
interest.  In September 1992, some of the Company's subsidiaries and MarAd
entered into an agreement (the "Storm Drilling Restructuring").  MarAd agreed
to (i) release one of the subsidiaries from its limited guarantee of interest
on another subsidiary's Title XI debt, (ii) not to take adverse actions against
the Company or its other subsidiaries or affiliates with respect to any
deficiencies remaining on the Title XI debt after the foreclosure or sale of
the subsidiary's rigs and (iii) take custody of the subsidiary's rigs.  In
addition to the foregoing, MDMC paid approximately $3,802 to MarAd from
litigation involving the MARINE 7.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  (CONTINUED)

    Quasi-Reorganization

         On December 31, 1992, the Company adopted quasi-reorganization
accounting procedures.  Quasi-reorganization accounting allowed the Company to
eliminate the accumulated deficit against additional paid-in capital and to
revalue assets and liabilities to estimated fair values.  Therefore, the
adoption of quasi-reorganization accounting procedures following the
Recapitalization gave the Company a "fresh start" for accounting purposes.

         The adoption of quasi-reorganization accounting procedures resulted in
a decrease to property and equipment of $56,051, a decrease in assets held for
sale of $240, a decrease in other assets of $9,043, a decrease in debt of
$8,054, a decrease in deferred expenses of $145, a decrease in receivables of
$112 and an increase in other liabilities of $25.

(2)      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND OPERATIONS

    Principles of Consolidation

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

    Operations

         As of December 31, 1994, the Company's fleet consisted of 13 jack-up
rigs.

    Property and Equipment

         Property and equipment are stated at historical cost or the cost
assigned to the assets at December 31, 1992 in connection with the adoption of
quasi-reorganization accounting procedures.  Depreciation is provided on the
straight-line method over the estimated remaining useful lives of the assets
which are as follows:

         Maintenance and repairs amounted to $8,600, $8,030 and $1,943 in 1994,
1993 and 1992, respectively.  Expenditures for major renewals and betterments
are capitalized.  Expenditures for normal maintenance and repairs are charged
to expense as incurred.  When property or equipment is retired, the related
assets and accumulated depreciation are removed from the accounts and a gain or
loss is reflected in other income (expense).  The Company continues to
depreciate idle drilling equipment using the same rates as while operating.

    Employer's Liability Claims

         Employer's liability claims, principally arising from actual or
alleged personal injuries, are estimates of the Company's liabilities for such
occurrences.  These claims are classified as current or long-term based upon
the periods in which such claims are expected to be funded.

    Deferred Financing Costs

         Deferred financing costs are amortized over the life of the related
debt.  Deferred financing costs were $228 at December 31, 1994.  Deferred
financing costs in 1992 of $1,003 were eliminated at December 31, 1992 in
connection with the adoption of quasi- reorganization accounting procedures or
were written off in connection with early extinguishments of debt.

    Income Taxes

         In February 1992, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes."  Statement 109 required a change from the deferred method of accounting
for income taxes of APB Opinion 11 to the asset and liability method of
accounting for income taxes.  Under the asset and liability method of Statement
109, deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases.  Deferred tax assets and liabilities are measured using enacted tax
rates expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled.  Under Statement 109, the
effect on deferred tax assets and liabilities of a change in tax rates is
recognized in income in the period that includes the enactment date.

         Effective December 31, 1992, in conjunction with the adoption of
quasi-reorganization accounting procedures, the Company adopted Statement 109.
The change in the method of accounting for income taxes had no cumulative
effect on the 1992 consolidated statements of operations.  Pursuant to the
deferred method under APB Opinion 11, which was applied during 1992 and prior
years, deferred income taxes are recognized for income and expense items that
are reported in different years for financial reporting purposes and income tax
purposes using the tax rate applicable for the year of the calculation.  Under
the deferred method, deferred taxes are not adjusted for subsequent changes in
tax rates.

    Revenue Recognition

         Drilling revenues are recorded pursuant to day rate contracts, under
which the Company receives a fixed amount per day for providing drilling
services using the rigs it operates.

    Cash Equivalents

         Cash equivalents of $18,531 and $21,396 at December 31, 1994 and 1993,
respectively, consist of loan participations, Eurodollar investments, mortgage
backed and corporate debt securities.  Their carrying value is a reasonable
approximation of their fair value.  For purposes of the statement of cash
flows, the Company generally considers all investments with an original
maturity of three months or less at date of purchase and other highly liquid
investments readily convertible to determinable amounts of cash, excluding
restricted cash investments, to be cash equivalents.

    Short-Term Investments

         Short-term investments consist of corporate debt securities,
mortgage-backed securities and corporate paper.  The Company classifies its
short-term investments as held-to-maturity securities.  Held-to-maturity
securities are those securities in which the Company has the ability and intent
to hold the security until maturity.  Held-to-maturity securities are recorded
at amortized cost, adjusted for the amortization or accretion of premiums or
discounts.  Premiums and discounts are amortized or accreted over the life of
the related held-to-maturity security as an adjustment to yield using the
effective interest method.  Dividend and interest income are recognized when
earned.  The fair value of the short-term investments at December 31, 1994 was
$18,133.

    Income (Loss) Per Common Share

         Income (loss) per common share is based on the weighted average number
of common shares outstanding and common stock equivalents, if dilutive.  For
the year ended December 31, 1992, the net income (loss) applicable to common
shareholders has been adjusted to reflect the dividends on and the accretion of
discount on Old Preferred Stock.  Net income per common share for the years
ended December 31, 1994 and 1993 do not include the effect of outstanding stock
options as the potential dilution from their exercise is less than three
percent.

    Reclassification of Accounts 

         Certain reclassifications have been made to the 1993 and 1992 
consolidated financial statements to conform with the current presentation.

    Concentrations of Credit Risk

         The market for the Company's services and products in the offshore oil
and gas industry, and the Company's customers consist primarily of independent
and major oil and gas companies.  The Company performs ongoing credit
evaluations of its customers and obtains collateral security as deemed prudent.
The Company has established an adequate allowance for bad debts, and such
losses have been within management's expectations (see Note 9).

         At December 31, 1994 and 1993, the Company had cash deposits
concentrated primarily in one major bank.  In addition, the Company had
certificates of deposits, commercial paper and Eurodollar time deposits with a
variety of companies and financial institutions with strong credit ratings, and
such securities are held until maturity.  The Company believes that credit and
market risk in such instruments is minimal.

(3)      PROPERTY AND EQUIPMENT

         Property and equipment are stated at historical cost or the cost
assigned to the assets at December 31, 1992 in connection with the adoption of
quasi-reorganization accounting procedures, and are summarized as follows:

    KHC - Note Payable to Lender

         On December 1, 1994, KHC entered into a $35,000 revolving/term loan
agreement (the "Loan") with a U.S. financial institution ("Lender").  As of
December 31, 1994, the related debt outstanding was $15,000 and the amount of
unused line of credit subject to the Loan was $20,000.  Loan proceeds may be
used to purchase additional jack-up drilling rigs or to make capital
improvements to the Company's existing drilling rig fleet.  The Company is a
guarantor for up to an aggregate of $8,750 under the Loan.  On June 1, 1996,
all amounts borrowed under the Loan may be converted to a term loan.

         If converted, the term loan will be due in thirty-six (36) consecutive
monthly installments, beginning July 1, 1996 and ending June 1, 1999 amortizing
at the rate of 20% of the term loan balance per year with the remaining 40%
principal balance due and payable concurrently with the last payment.  KHC must
maintain a minimum borrowing of $10,000 (the "minimum borrowing") on the Loan
after June 1, 1996.  If the Company's average borrowings under the revolving
loan or the term loan are less than the minimum borrowing, KHC will be required
to pay a non-utilization fee of 2% of the difference between the actual average
borrowed balance and the minimum borrowing.  The term loan may be prepaid at
any time after the eighteenth payment (December 1, 1997).  A prepayment premium
of 1% of the prepaid principal amount will be due with each such prepayment.
Repayments may not be re-borrowed during the term loan period.

         Interest is due monthly on the outstanding principal balance at the
London Interbank Offered Rate ("LIBOR") plus 2.5%.  The interest rate as of
December 31, 1994 was 7.938%.  A revolving loan fee is due quarterly during the
revolving loan period based on the unused credit facility at .25%.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  (CONTINUED)

         The note is secured by a first preferred fleet mortgage on the MARINE
300, 301 and 303 drilling rigs.  The three drilling rigs must be appraised on
the term loan conversion date, June 1, 1996.  The term loan will be limited to
50% of the appraised value of the rigs.  The Company and KHC are required to
comply with various covenants, including, but not limited to, the maintenance
of financial ratios related to (i) debt to total equity and (ii) working
capital to fixed expenses and projected debt services.


         Interest payments on the loan amounted to $70 for the year ended
December 31, 1994, including a revolving loan fee of $5.  A facility fee of
$175 was paid to the lender during the fourth quarter 1994 and will be
amortized over the life of the loan.

         The scheduled repayment of long-term debt as of December 31, 1994 is

         As a result of the adoption of quasi-reorganization accounting
procedures on December 31, 1992, the tax effect of the realization of tax
attributes generated prior thereto are recorded directly to shareholders'
equity and are not reflected as a reduction of income tax expense.

         For the years ended December 31, 1994 and 1993, the effective tax rate
for financial reporting purposes approximates the U.S. federal statutory rate
of 35%.

</TABLE> 

         The valuation allowance for deferred tax assets as of December 31,
1994 and 1993 was $38,649 and $42,209, respectively.  The net change in the
total valuation allowance for the years ended December 31, 1994 and 1993 was a
decrease of $3,560 and an increase of $2,615, respectively.  In assessing the
realizability of deferred tax assets, management considers whether it is more
likely than not that some portion or all of the deferred tax assets will not be
realized.  Management considers the scheduled reversal of deferred tax
liabilities, projected future taxable income, and tax planning strategies in
making this assessment.  Based upon projections for future taxable income over
the periods which the deferred tax assets are deductible and the Section 382
limitation as discussed below, management believes it is more likely than not
that the Company will realize the benefits of these deductible differences, net
of the existing valuation allowances at December 31, 1994.

         At December 31, 1994, the Company had net operating loss carryforwards
for federal income tax purposes of $82,296 which are available to offset future
federal taxable income, if any, through 2007.  The Company also had investment
tax credit and general business credit carryforwards for federal income tax
purposes of approximately $13,410 (including $1,844 which are subject to the
limitation as to their use imposed in connection with the 1989 Ownership Change
as discussed below) at December 31, 1994 which are available to reduce future
federal income taxes, if any, through 2000.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  (CONTINUED)

         The Company has taken the position that the Recapitalization did not
cause an ownership change under Section 382 of the Internal Revenue Code of
1986, as amended ("Code").  The Company's position is based on the
applicability of Section 382(l)(3)(C) of the Code, which provides generally
that any change in the proportionate ownership attributable solely to
fluctuations in relative fair market value of different classes of stock are
not to be taken into account for purposes of Section 382.  To date, neither the
Internal Revenue Service nor the United States Department of Treasury has
established any rules or guidance as to how such Section will be interpreted or
applied to situations similar to the Recapitalization.  Accordingly, there can
be no assurance that an ownership change for purposes of Section 382 will not
be deemed to have occurred as a result of the Recapitalization.  If an
ownership change were deemed to have occurred, the utilization of the Company's
net operating losses, against its future income, if any, would be limited
annually to approximately $1,500.  Since such limitation would be less than the
Section 382 limitation (approximately $9,000) imposed as a result of the
Company's 1989 sale of Common Stock which resulted in an ownership change
("1989 Ownership Change") pursuant to Section 382 of the Code, the Section 382
limitation imposed in connection with the Recapitalization would apply to all
net operating losses applicable to the period before the Recapitalization.

 (7)     LONG TERM INCENTIVE PLANS

         On September 14, 1992, the Company's Board of Directors adopted the
Marine Drilling 1992 Long Term Incentive Plan ("1992 Plan"), which was
subsequently approved by the shareholders on October 29, 1992.  Pursuant to the
terms of the 1992 Plan, an aggregate of 10,000,000 shares (subject to the
restrictions described herein) of Common Stock are available for distribution
pursuant to stock options, SARs and restricted stock.  The number of shares of
Common Stock available for distribution as described above is further limited
in that no stock options, SARs or restricted stock may be issued if,
immediately after such issuance, the number of shares subject to outstanding
stock options, SARs and restricted stock awards would exceed 5% of the Common
Stock then outstanding.  The shares of Common Stock subject to any stock option
or SAR that terminates without a payment being made in the form of Common Stock
would again become available for distribution pursuant to the 1992 Plan.
During 1994 and 1993, respectively, the Company issued 83,000 and 385,000
shares of restricted Common Stock.  Compensation expense related to the
issuance of restricted Common Stock for the years ended December 31, 1994 and
1993 was $318 and $233, respectively.  During 1994 and 1993, respectively,
31,250 and 30,000 shares of restricted Common Stock were forfeited.

         Holders of SARs and options granted under the plans existing prior to
the adoption of the 1992 Plan surrendered such SARs and options in exchange for
options under the 1992 Plan and those prior plans have been terminated.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  (CONTINUED)


         During the fourth quarter 1992, 1,440 SARs and 21,640 shares subject
to options outstanding under prior plans were exchanged for 23,080 shares
subject to option at $1.25 per share under the 1992 Plan.  Additionally,
options for 1,590,000 shares exercisable at $1.25 were granted on November 3,
1992, options for 190,000 shares exercisable at $6.00 were granted on June 29,
1993 and options for 75,000 shares exercisable at $4.25 were granted on October
12, 1994.  All such options expire November 2002, June 2003 and October 2004,
respectively, unless earlier exercised.  During 1993, 261,030 shares were
exercised at $1.25 per share and options for 1,400 shares were forfeited.
During 1994, 10,000 shares were exercised at $1.25 per share and options for
30,000 shares were forfeited.

         There were no significant international operations during 1992.

         The Company conducts business in one industry segment, oil and gas
well contract drilling.  The Company negotiates drilling contracts with a
number of customers for varying terms, and management believes it is not
dependent upon any single customer.  For the years 1994, 1993 and 1992, sales
to customers that represented 10% or more of consolidated drilling revenues
were as follows:

   *  Less than 10%

         As is typical in the industry, the Company does business with a
relatively small number of customers at any given time.  The loss of any one of
such customers could, at least on a short-term basis, have a material adverse
effect on the Company's profitability.  Management believes, however, that at
current levels of drilling activity, the Company would have alternative
customers for its services if it lost any single customer and that the loss of
any one customer would not have a material adverse effect on the Company on a
long-term basis.

(1)   Quarterly net income per common share may not total to annual results due
      to rounding.
(2)   "Average day rate" is determined by dividing the total gross revenue
       earned by the Company's rigs during a given period by the total number
       of days that the Company's rigs were under contract during that
       period.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  (CONTINUED)

   In 1994, the average day rates earned by the Company's rigs generally
declined throughout the year, however, the adverse effects of these declines
were partially offset by sequentially higher rig utilization rates through
those quarters.  The decline in day rates during 1994 was due primarily to (i)
increased competition in the U.S. Gulf of Mexico arising from an increased
supply of jack-up rigs in that market and (ii) reduced activity levels in
Mexico's Bay of Campeche.

   Quarterly results during 1993 were virtually the reverse of 1994's due to
general day rate increases occurring throughout the year experienced
concurrently with consistently high levels of rig utilization.  These
attributes were the results of (i) a better balance between jack-up rig supply
and demand in the U.S. Gulf of Mexico and (ii) high activity levels in the Bay
of Campeche.

(12) SUBSEQUENT EVENTS (UNAUDITED)

   On November 2, 1994, the Company and Falcon Drilling Company, Inc.
("Falcon") signed a letter of intent to merge.  On February 15, 1995, Falcon
and the Company agreed to terminate the letter of intent and related
discussions because then current market conditions led both parties to conclude
that a definitive agreement could not be reached at that time.

   On February 28, 1995, the Company repaid $5,000 of the revolving credit
facility associated with the Loan described in Note 5 hereto.  The Company
anticipates that amount will be re-borrowed in addition to other borrowings in
1995 to fund capital expenditures.

   Weakness in natural gas prices contributed to a substantial downturn in U.S.
Gulf of Mexico drilling activity in early 1995.  As a result, the Company's
operations and cash flow have been adversely affected.  In response to these
conditions, the Company has elected to temporarily deactivate some of its rigs
and may deactivate additional rigs until market conditions improve.

   On March 7, 1995, the Company announced that its Board of Directors had
authorized the repurchase of up to 4,000,000 shares of the Company's Common
Stock.  The purchases may be effected, from time to time, in accordance with
applicable securities laws, through solicited or unsolicited transactions in
the market or in privately negotiated transactions.  No limit was placed on the
duration of the repurchase program.  Subject to applicable securities laws,
such repurchases shall be at such times and in such amounts as the Company
deems appropriate.  The Company will fund such repurchases from working
capital.

2.01 of this Agreement, the Lender agrees to make Advances to the Borrower in

and (2) USD 35,000,000 (the "Loan").

         Section 1.02 Revolving Loan Period.  (a)  During the Revolving Loan
Availability Period, the Lender agrees to make Advances to the Borrower from
time to time on any Business Day in the aggregate not to exceed the amount of
the Loan available to the Borrower referred to in Section 1.01 hereof.  All
Advances shall be used by the Borrower for the purchase of jack-up drilling
rigs and to make capital improvements to the existing drilling rig fleet of the
Borrower and its affiliates.  Each Advance shall be in an integral multiple of
One Million United States Dollars (USD 1,000,000) and no more than one Advance
shall be made by the Lender during any thirty (30) calendar days.  Within the
limits referred to above, the Borrower may borrow, prepay and reborrow under

         (b)     The Borrower shall make a request for an Advance by sending to

Time, three (3) Business Days prior to the date such Advance is requested
setting forth the date the Advance is required and the bank account or accounts
to which the Advance is to be remitted.  The first Notice of Drawing shall be
received by the Lender no later than three (3) Business Days immediately
preceding the Closing Date.  All Notices of Drawing shall be irrevocable.  As
used in this Agreement, the term "Closing Date" shall mean any Business Day
occurring on or prior to December 1, 1994 which shall be the day on which the
first Advance is to be made as designated by the Borrower in its Notice of
Drawing.

         Section 1.03 Term Loan Period.  (a)  On the Term Loan Conversion Date,
all amounts outstanding under the Loan will be converted to a thirty six (36)
month term loan.  During the Term





                                      -5-
<PAGE>   9
Loan Period, the Lender shall make no further Advances to the Borrower
hereunder.

         (b)  In the event that the amount of the Loan outstanding on the Term
Loan Conversion Date is less than USD 10,000,000, the Borrower shall pay to the
Lender on the Term Loan Conversion Date a non-utilization fee equal to the
difference between USD 10,000,000 and the amount of the Loan then outstanding,
multiplied by two percent (2%).

         (c)  The Borrower shall repay the principal amount of the Note in
thirty-six (36) consecutive monthly installments, each such installment to be
paid by the Borrower to the Lender on a Payment Date commencing July 1, 1996
and ending on the Maturity Date.  The amount of principal to be repaid on each
Payment Date shall be the amount necessary to amortize (over thirty-six equal
monthly installments) sixty percent (60%) of the balance of the Loan
outstanding on the Term Loan Conversion Date, provided, however, that such
final installment shall include a balloon amount sufficient to discharge the
accrued and unpaid interest, unpaid principal and unpaid premium, if any, in
respect of the Note.

         (d)  The Loan shall be evidenced by and repayable in accordance with
the terms hereof and of the Note.

         Section 1.04 Interest.

         (a)  The Borrower shall pay interest, in arrears, on the unpaid
principal amount of the Note from the Closing Date until the principal amount
of the Note is paid in full on the last Business Day of each calendar month,
commencing December 30, 1994 to and including the Maturity Date (each such date
a "Payment Date") at a rate of interest per annum (computed on the basis of a
360-day year of twelve 30 day months) equal to the Interest Rate provided,
however, that all interest accrued on the Loan and unpaid on the Maturity Date
shall be paid on the Maturity Date.

         (b)     The term "Interest Rate" shall mean, for an Interest Period
(as hereinafter defined), an interest rate equal to the LIBOR Rate (as
hereinafter defined) plus 2.5% per annum, subject to periodic adjustment as
provided below.  "LIBOR Rate" means the thirty (30) day rate of interest per
annum at which deposits in United States Dollars are offered in London, England
to prime banks in the London interbank market as published in The Wall Street
Journal for the fifteenth (15th) day of each calendar month during the term of
the Loan.  (If the 15th day of the calendar month is not a day for which The
Wall Street Journal reports the LIBOR Rate, then for the first preceding day on
which The Wall Street Journal reports the LIBOR Rate).  The LIBOR Rate shall
become effective as of the first day of the calendar month next succeeding each
such





                                      -6-
<PAGE>   10
determination and shall continue in effect to, and including the last day of
the calendar month.  If at any time the Lender shall determine that by reason
of circumstances affecting the London interbank market (u) adequate and
reasonable means do not exist for ascertaining the LIBOR Rate for the
succeeding Interest Period or (v) the making or continuance of the Loan at the
LIBOR Rate has become impracticable as a result of a contingency occurring
after the date of this Agreement which materially and adversely affects the
London interbank market, the Lender shall notify the Borrower.  As used in this
Agreement, "Interest Period" shall mean each respective and successive one
month calendar period commencing on the Closing Date or the last day of the
immediately preceding Interest Period, as the case may be, provided, however,
that (y) if any Interest Period includes a Payment Date, but does not end on
such date, then the principal amount of the Loan required to be paid on such
date shall have an Interest Period ending on such date and (z) no Interest
Period shall commence or extend past the Maturity Date of the Note.

         (c)     Any amount of principal or any other amount due hereunder
which is not paid when due, whether at stated maturity, by acceleration or
otherwise, shall bear interest from the date when due until such amount is paid
in full, payable on demand, at a rate per annum equal at all times to 2% above
the Interest Rate.

         (d)     In no event shall any interest rate provided for in this
Agreement or the Note exceed the maximum rate permitted by the then applicable
law.  It is the intention of the parties hereto to strictly comply with
applicable usury laws; accordingly, it is agreed that, notwithstanding any
provision to the contrary in this Agreement, in the Note, or in any other Loan
Document, in no event shall this Agreement, the Note, or the other Loan
Documents be construed to charge, contract for or require the payment or permit
the collection of interest in excess of the maximum amount permitted by
applicable law.  If any such excess interest is contracted for, charged or
received under this Agreement, the Note or the other Loan Documents, or in the
event that all of the principal balance shall be prepaid, so that under any of
such circumstances the amount of interest contracted for, charged or received
on the principal balance shall exceed the maximum amount of interest permitted
by applicable law, then in such event (i) the provisions of this Section
1.04(d) shall govern and control, (ii) neither the Borrower nor any other
person or entity now or hereafter liable for the payment thereof shall be
obligated to pay the amount of such interest to the extent that it is in excess
of the maximum amount of interest permitted by applicable law, (iii) any such
excess which may have been collected shall be either applied as a credit
against the then unpaid principal balance or refunded to the Borrower, at the
option of the Lender, and (iv) the effective rate of interest shall be
automatically reduced to the





                                      -7-
<PAGE>   11
maximum lawful contract rate allowed under applicable law as now or hereafter
construed by the courts having jurisdiction thereof.  It is further agreed that
without limitation of the foregoing, all calculations of the rate of interest
contracted for, charged or received under this Agreement, the Note and the
other Loan Documents which are made for the purpose of determining whether such
rate exceeds the maximum lawful contract rate, shall be made, to the extent
permitted by applicable law, by amortizing, prorating, allocating and spreading
in equal parts during the period of the full stated term of the indebtedness
evidenced hereby, all interest at any time contracted for, charged or received
from the Borrower or otherwise by the Lender in connection with such
indebtedness; provided, however, that if any applicable state law is amended or
the law of the United States of America preempts any applicable state law, so
that it becomes lawful for the Lender to receive a greater simple interest per
annum rate than is presently allowed, the Borrower agrees that, on the
effective date of such amendment or preemption as the case may be, the lawful
maximum hereunder shall be increased to the maximum simple interest per annum
rate allowed by the higher of the amended state law or the law of the United
States of America.

         Section 1.05 Payments.

         (a)  The payment obligations of the Borrower under the Note and all
other amounts payable under this Agreement to the Lender shall be paid, in
immediately available funds, to the Lender at Chemical Bank, 640 Madison
Avenue, New York, New York 10021, ABA No. 021-000-128, for credit to the
account of The CIT Group/Equipment Financing, Inc., Account No. 134-086460
(ref. Keyes Holding, Contract No. 8122) or at such other place as the Lender
may designate not less than one (1) Business Day prior to the due date
therefor, in immediately available funds, not later than the close of business
on the due date thereof, in lawful money of the United States.  All payments
shall be made (i) without set-off, counterclaim or condition and (ii) free and
clear of, and without deduction for or on account of, any present or future
taxes, levies, duties, imposts, charges, fees, deductions or withholdings of
any nature ("Taxes"), unless the Borrower is required by law or regulation to
make payment subject to any Taxes.  In the event that the Borrower is required
by law or regulation to make any deduction or withholding on account of any
Taxes from any payment due under this Agreement, then:  (a) the Borrower shall
notify the Lender promptly as soon as it becomes aware of such requirement and
shall remit promptly the amount of such Taxes to the appropriate taxation
authority, and in any event prior to the date on which penalties attach
thereto; and (b) such payment shall be increased by such amount as may be
necessary to ensure that the Lender receives a net amount, free and clear of
all Taxes, equal to the full amount which the Lender would have received had
such payment not been subject to





                                      -8-
<PAGE>   12
such Taxes (other than Excluded Income Taxes as such term is defined below).
Notwithstanding the foregoing, the Borrower shall not be liable for, or
required to pay, any Taxes which are overall income or franchise taxes imposed
at any time on the Lender in the United States of America or any state or local
government or taxing authority in any state in which the Lender conducts
business ("Excluded Income Taxes").  Each such payment or reimbursement by the
Borrower shall be net of any credit or the value of any deduction received by
the Lender thereon to the extent that the same can be determined by the Lender
(as certified by the Lender to the Borrower, such certificate to be conclusive
absent manifest error).  The Borrower shall indemnify the Lender against any
liability of the Lender in respect of such Taxes and shall supply copies of
applicable tax receipts.

         (b)     If any payment to be made by the Borrower shall become due on
a day which is not a Business Day, such payment shall be made on the next
succeeding Business Day.

         (c)     Each payment to be made on a Payment Date and all prepayments
and other payments shall be applied first to the payment of accrued and unpaid
interest on the Note, then to the payment of all other amounts due under this
Agreement and the Loan Documents, and the balance shall be applied to the
payment of principal due under the Note.

         (d)     The Borrower shall indemnify the Lender on demand against all
costs, expenses, liabilities and losses (including funding losses) sustained or
incurred by the Lender as a result of or in connection with:  (a) the
occurrence and/or continuance of any Event of Default (or event which, with the
giving of notice and/or lapse of time or other applicable condition might
constitute an Event of Default); and/or (b) any judgment or order which relates
to any sum due hereunder being expressed in a currency other than the currency
expressed to be due hereunder and as a result of a variation in rates of
exchange between the rate at which such amount is converted into such other
currency for the purposes of such judgment or order and the rate prevailing on
the date of actual payment of such amount pursuant thereto; and/or (c) any
postponement of the Closing Date occurring because of one or more of the
conditions precedent set forth in Section 2.01 shall not have been satisfied or
waived; and/or (d) any payment of principal of or interest on the Note made on
a date which is not a Payment Date.  The above indemnities are separate and
independent obligations of the Borrower and apply irrespective of any
indulgence granted by the Lender.

         Section 1.06 Prepayment.

         (a)  Mandatory Prepayment.

                 (i)      Total Loss.  If there shall have occurred a Total
         Loss as herein defined, on the earlier of (x) the date insurance
         proceeds are received or (y) ninety (90) days after the date of
         occurrence of the Total Loss, the Borrower shall (A) prepay the
         outstanding principal balance under the Note in an amount equal to the
         outstanding principal amount of the Loan on the date of prepayment
         (without counting any amount being prepaid on such date), multiplied
         by a fraction, the numerator of which is Fair Market Value of the lost
         Vessel as most recently determined under Section 1.06(a)(iii) and the
         denominator of which is the Vessel Value as of such date (including
         the lost Vessel), and (B) pay accrued interest thereon to the date of
         such prepayment together with any other amount due hereunder or under
         any Loan Document.  The Lender shall apply payments received pursuant
         to this Section 1.06(a)(i) in accordance with Section 1.05(c)
         hereof, provided, however, that the principal repayments shall be
         applied so that the remaining installments of principal, if any, are
         reduced on a pro rata basis, such reduction to be confirmed by the
         Lender in a certificate delivered to the Borrower which certificate
         shall be conclusive absent manifest error.  No Prepayment Premium
         shall be payable with respect to any Mandatory Prepayments made by the
         Borrower pursuant to this Section 1.06(a)(i). "Total Loss" means in
         respect of a Vessel (i) actual or constructive or compromised or
         arranged total loss of such Vessel; or (ii) requisition for title or
         other compulsory acquisition of such Vessel otherwise than by
         requisition for hire; or (iii) capture, seizure, arrest, detention or
         confiscation of such Vessel by any government or by persons acting or
         purporting to act on behalf of any government unless such Vessel is
         released from such capture, seizure, arrest, detention or confiscation
         within thirty days of the occurrence thereof.  A Total Loss shall be
         deemed to have occurred (a) in the event of an actual total loss of a
         Vessel, on the date of such loss, (b) in the event of damage to a
         Vessel which results in a constructive or compromised or arranged
         total loss of such Vessel, on the date of the occurrence of the event
         giving rise to such damage, or (c) in the case of any event referred
         to in Clauses (ii) or (iii) above, on the date of the occurrence of
         such event.  In the event of any Total Loss or requisition of a
         Vessel, the Borrower shall give written or telegraphic notice to the
         Lender not later than ten (10) days after a Responsible Officer of the
         Borrower has actual knowledge of such occurrence.





                                      -10-
<PAGE>   14
                  (ii) Collateral Value.  On or before the Closing Date and
         again on the Term Loan Conversion Date, the Lender shall arrange
         to have the Fair Market Value of each of the Vessels determined at the
         Borrower's expense by one independent drilling rig brokering firm
         nominated by the Borrower from a list of three independent drilling
         rig brokering firms compiled by the Lender.  Each such valuation shall
         be based on the Fair Market Value of each Vessel.  The aggregate of
         the most recent valuations of each Vessel is hereinafter referred to
         as the "Vessel Value".  If, on the Term Loan Conversion Date, the
         outstanding principal amount of the Loan shall exceed fifty percent
         (50%) of Vessel Value, then the Borrower shall either prepay within
         five days of Lender's demand the amount of the Loan necessary to
         restore the ratio referred to herein together with payment of accrued
         interest thereon and the Prepayment Premium or provide additional
         security for the Loan which shall be acceptable in the sole opinion of
         the Lender for these purposes.  The Lender shall apply payments
         received under this Section 1.06(a)(ii) in accordance with Section
         1.05(c) hereof, provided, however, that the principal repayments shall
         be applied so that the remaining installments of principal, if any,
         shall be reduced on a pro rata basis, such reduction to be confirmed by
         the Lender in a certificate delivered to the Borrower which
         certificate shall be conclusive absent manifest error.

                  (iii)  Fair Market Value.  The "Fair Market Value" of any
         Vessel shall be the value determined by the independent drilling rig
         brokering firm chosen by the Borrower in accordance with clause (ii)
         above on the basis of an arm's-length purchase by a willing buyer from
         a willing seller and without consideration of any drilling contract,
         charter party or other vessel employment contract.  The drilling rig
         brokering firm's valuation shall be made without physical inspection,
         unless otherwise required by the Lender.

         (b)  Voluntary Prepayment during Term Loan Period.  After the
eighteenth (18th) Payment Date of the Term Loan Period, the Borrower may prepay
in full or in part in amounts of not less than USD 1,000,000, its indebtedness
under the Note on the next Payment Date after giving at least thirty (30)
Business Days prior notice of such prepayment and payment to the Lender of
accrued and unpaid interest under the Note and all other amounts due under this
Agreement and the other Loan Documents including a premium in an amount equal
to one percent (1%) of the principal amount prepaid (the "Prepayment Premium").
Any notice of prepayment hereunder shall be irrevocable.

         The Lender shall apply payments received pursuant to this Section
1.06(b) in accordance with Section 1.05(c) hereof,





                                      -11-
<PAGE>   15
provided, however, that the principal repayments shall be applied so that the
remaining installments of principal, if any, shall be reduced on a pro rata
basis, such reduction to be confirmed by the Lender in a certificate delivered
to the Borrower which certificate shall be conclusive absent manifest error.

         (c)  Voluntary Prepayment during Revolving Loan Availability Period.
During the Revolving Loan Availability Period the Borrower may prepay amounts
outstanding under the Loan on the following terms and conditions: (i) the
Borrower shall give the Lender at least three (3) Business Days' prior written
notice of its intent to prepay the Loan and the amount of such prepayment; (ii)
such repayments are made no more than once each calendar month; and (iii) each
prepayment of the Loan shall be in a principal amount of at least USD
1,000,000.  No Prepayment Premium shall be due for any prepayment under this
Section 1.06(c).

         Section 1.07 Security.   All amounts due hereunder and under the Note
shall be secured by the following, each in form and substance satisfactory to
the Lender (A) the Mortgage, (B) the Earnings Assignment, (C) the Insurance
Assignment and (D) the Guaranty.

         Section 1.08 Facility Fee.  The Borrower shall pay to the Lender a
non-refundable facility fee equal to USD 175,000 which shall be paid to the
Lender on or before the Closing Date.

         Section 1.09 Revolving Loan Fee.  The Borrower shall pay to the Lender
a revolving loan fee of one quarter of one percent (.25%) per annum on the
unused portion of the Loan during the Revolving Loan Availability Period,
computed on the difference between USD 35,000,000 and the average daily
outstanding balance of the Loan, payable quarterly in arrears on the last
Business Day of each calendar quarter, beginning December 30, 1994.

assessment received by it to the extent that such taxes have become due and
except as to such taxes being contested in good faith by appropriate
proceedings for which adequate reserves are being maintained.  The Borrower has
set up reserves to the extent believed by it to be adequate for the





                                      -16-
<PAGE>   20
payment of additional taxes for years which have not been audited by the
respective tax authorities.

         (i)  The Borrower has no subsidiaries other than its permanent

         the use or ownership of the Vessels or other properties owned or
         operated by the Borrower.

                 (iii)  The Borrower has been issued all required permits,
         licenses, certificates and approvals of all Governmental Agencies
         relating to (a) air emissions, (b) discharges to surface water or

                 the Vessels or any other properties owned or operated by the
                 Borrower except as may arise upon enforcement of the Lender's  
                 rights under the Mortgage.

                          (B)     Should, however, the Lender hereafter
                 exercise any ownership interest in or operational control over

                 Borrower, e.g., including but not limited to, through
                 foreclosure, then the above stated indemnity and hold harmless
                 shall be limited with respect to any actions or

                 failures to act by the Lender subsequent to exercising such
                 interest or operational control, to the extent such action or
                 inaction by the Lender is found by a court or Governmental
                 Agency with competent jurisdiction to have caused or made
                 worse any condition for which liability is asserted, including
                 but not limited to, the presence, escape, seepage, spillage,
                 leaking, discharge or migration on or from the Vessels or

         timely manner any such case under the Bankruptcy Code or any such

         case or proceeding is entered; or

                 (v)    either the Borrower or the Guarantor by any act or

         Section 5.03 Applicable Law and Jurisdiction.  (a)  This Agreement and
the Loan Documents provided for herein (including, but not limited to, the
validity and enforceability hereof and thereof) shall be governed by, and
construed in accordance with, the laws of the State of New York, other than
conflict of laws rules thereof.  Any legal action or proceeding against the
Borrower or the Guarantor with respect to this Agreement or any Loan Document
may be brought in the courts of the State of New York, the U.S. Federal Courts
in such state, sitting in the County of New York, or in the courts of any other
jurisdiction where such action or proceeding may be properly brought, and each
of the Borrower or the Guarantor hereby irrevocably accepts the jurisdiction of
such courts for the purpose of any action or proceeding.  Each of the Borrower
and the Guarantor hereby designates and irrevocably appoints and empowers C T
Corporation System (the "Process Agent"), currently located at 1633 Broadway,
New York, New York 10019 in each case as its authorized agent to accept,
receive and acknowledge for and on behalf of each and its property service of
any and all process which may be served but only in any action, suit or
proceeding of the nature referred to above in the State of New York and further
agrees that failure of such firm to give the Borrower and the Guarantor, as the
case may be, any notice of any such service shall not impair or affect the
validity of such service or of any judgment rendered in any action or
proceeding based thereon.  Each of the Borrower and the Guarantor hereby
irrevocably authorizes and directs the Process Agent to accept such service on
its behalf.  Each of the Borrower and the Guarantor further irrevocably
consents to the service of process out of said courts by the mailing thereof by
the Lender by U.S. registered or certified mail postage prepaid to the party to
be served at its address designated in Section 5.01.  Each of the Borrower and
the Guarantor agree that a final judgment in any action or proceeding shall be
conclusive and may be enforced in any other jurisdiction by suit on the
judgment or in any other manner provided by law.  Nothing in this Section 5.03
shall affect the right of the Lender to serve legal process in any other manner
permitted by law or affect the right of the Lender to bring any action or
proceeding against the Borrower or the Guarantor or their respective properties
in the courts of any other jurisdiction.  To the extent that the Borrower or
the Guarantor has or hereafter may acquire any immunity from jurisdiction of
any court or from any legal process (whether through service of notice,
attachment prior to judgment, attachment in aid of execution, execution or
otherwise) with respect to either itself or its respective property, each of
the Borrower and the Guarantor hereby irrevocably waive such immunity in
respect of its obligations under this Agreement and the other Loan Documents.
Each of the Borrower and the Guarantor hereby irrevocably waive any objection
which it may now or hereafter have to the laying of venue of any suit, action
or proceeding arising out of or relating to this Agreement or any Loan Document
brought





                                      -30-
<PAGE>   34
in the Supreme Court of the State of New York, County of New York or the U.S.
District Court for the Southern District of New York, and hereby further
irrevocably waives any claim that any such suit, action or proceeding brought
in any such court has been brought in an inconvenient forum.

         (b)  THE LENDER AND THE BORROWER AND THE GUARANTOR IRREVOCABLY WAIVE
ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING
OUT OF OR RELATING TO THIS AGREEMENT, THE NOTE OR ANY OTHER LOAN DOCUMENT OR
THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

         (c)  If for the purposes of obtaining a judgment in any court it
becomes necessary to convert the sum due hereunder or under any of the other
Loan Documents or under any instrument delivered hereunder or thereunder in
United States Dollars into another currency, the parties hereto agree, to the
fullest extent permitted by law, that the rate of exchange used shall be that
at which in accordance with normal banking procedures the Lender would purchase
United States Dollars with such other currency on the Business Day preceding
that on which the final judgment is given.  The obligation of the Borrower or
the Guarantor in respect of any sum due to the Lender hereunder or under any of
the Loan Documents or under any instrument delivered hereunder or thereunder
shall, notwithstanding any judgment in currency other than United States
Dollars, be discharged only to the extent that on the Business Day following
receipt by the Lender of any sum adjudged to be so due in such other currency,
the Lender may in accordance with normal banking procedures purchase United
States Dollars with such other currency; if the United States Dollars so
purchased are less than the sum originally due to the Lender in United States
Dollars, the Borrower and the Guarantor agree, as a separate obligation and
notwithstanding any such judgment, to indemnify the Lender against such loss
and if the United States Dollars so purchased exceed the sum originally due to
the Lender, in United States Dollars, the Lender agrees to remit to the
Borrower or the Guarantor, as the case may be, such excess.

         Section 5.04 Severability.  In the event that any provision of this
Agreement is held to be void or unenforceable in any jurisdiction, all other
provisions shall remain unaffected and be enforceable in accordance with their
terms in such jurisdiction, and all provisions of this Agreement shall remain
unaffected and shall be enforceable in accordance with their terms in all other
jurisdictions.

         Section 5.05 Amendment.  Neither this Agreement nor any provision
hereof, including without limitation this Section 5.05, may be amended,
modified, waived, discharged or terminated orally, but only by an instrument in
writing signed by the party against





                                      -31-
<PAGE>   35
which enforcement of the amendment, modification, waiver, discharge or
termination is sought.  This Agreement shall be binding upon and inure to the
benefit of the Borrower, the Guarantor and the Lender and their respective
successors and assigns, except that neither the Borrower or the Guarantor shall
have the right to assign their respective rights hereunder or any interest
herein without the prior written consent of the Lender.

         Section 5.06 Assignment and Participation.  The Lender shall have the
right to assign or grant participations in all or any portion of the Loan
outstanding under this Agreement or the Note to any affiliate of the Lender or
to any foreign, federal or state banking institution, savings and loan
institution or finance company upon thirty (30) days written notice to the
Borrower of such assignment or participation.

         Section 5.07 Costs, Expenses and Taxes.  The Borrower agrees to pay on
demand all reasonable fees, costs and expenses in connection (i) with the
preparation, execution, delivery, administration, amendment and enforcement of
this Agreement, the Note, any other Loan Document and any other documents to be
delivered hereunder and thereunder (including, without limitation, the
appraisal and inspection and survey reports required hereunder) and any
amendment, modification or supplement hereto or thereto, including, without
limitation, the reasonable fees and out-of-pocket expenses of counsel for the
Lender, and any special counsel associated with them, and with respect thereto
and the filing of any document or instrument in connection with any of the
foregoing, (ii) with respect to fees and expenses of counsel for advising the
Lender as to its rights and responsibilities under this Agreement and the
transactions contemplated thereby after an Event of Default or an event which,
with the giving of notice or lapse of time, or both, shall have occurred, and
(iii) with any filing or recording of any document or instrument.  In addition,
the Borrower shall pay any and all stamp and other taxes (including, without
limitation penalties and interest assessed thereon) other than Excluded Taxes
payable or determined to be payable in connection with the execution, delivery
or performance of this Agreement and the Loan Documents and any other documents
to be delivered hereunder and thereunder and agrees to save the Lender harmless
from and against any and all liabilities with respect to or resulting from any
delay in paying or omission to pay such taxes.

         Section 5.08 Counterparts.  This Agreement may be executed in two or
more counterparts, each of which shall constitute an original, but all of
which, when taken together, shall constitute but one instrument.

         Section 5.09 Section Heading.  The heading of the various Sections and
subsections of this Agreement are for convenience of reference only and shall
not define or limit any of the terms or provisions hereof.

         Section 5.10 Merger.  THIS AGREEMENT AND THE LOAN DOCUMENTS EMBODY THE
ENTIRE AGREEMENT BETWEEN THE BORROWER AND THE GUARANTOR ON THE ONE HAND AND THE
LENDER ON THE OTHER HAND AND SUPERSEDE ALL PRIOR AGREEMENTS, REPRESENTATIONS
AND UNDERSTANDINGS, IF ANY, RELATING TO THE SUBJECT MATTER HEREOF AND THEREOF.

                            SECURED PROMISSORY NOTE

USD 35,000,000

         The undersigned (the "Borrower") for value received, hereby promises
to pay to the order of THE CIT GROUP/EQUIPMENT FINANCING, INC. (the "Lender")
or any subsequent holder hereof the principal sum of Thirty Five Million United
States Dollars (USD 35,000,000) or such lesser amount as may be loaned to the
Borrower pursuant to a Loan Agreement dated as of December 1, 1994 among the
Borrower, Marine Drilling Companies, Inc., as Guarantor and the Lender (the
"Loan Agreement").

                             PRINCIPAL AND INTEREST

         1.1     (a)      Interest on this Note shall be payable at the times
and the rates as provided in Section 1.04 of the Loan Agreement.

         (b)     Subject to the terms of Section 1.5 hereof, in case any
payment of principal or interest is not paid when due, additional interest at
the rate determined as provided in Section 1.04(c) of the Loan Agreement shall
be payable on all overdue principal and, to the extent that the same may be
lawful, on all overdue interest.

         1.2     Interest shall be calculated as provided in Section 1.04(b) of
the Loan Agreement.

         1.3     The principal of this Note shall be payable in installments as
provided in Section 1.03(c) of the Loan Agreement and in such amounts as are
set forth in Schedule 1 hereto.

         1.4     All principal, interest, premium, if any, and other amounts
due hereunder shall be payable in lawful money of the United States of America
in immediately available funds to the Lender at Chemical Bank, 640 Madison
Avenue, New York, New York 10021, ABA No. 021-000-128, for credit to The CIT
Group/Equipment Financing, Inc., Account No. 134-086460 (ref. Keyes Holding,
Contract No. 8122) as provided in Section 1.05 of the Loan Agreement.

         1.5     In no event shall any interest rate provided for in this
Note exceed the maximum rate permitted by the then applicable law.  It is
the intention of the Lender and the Borrower to strictly comply with applicable
usury laws; accordingly, it is agreed that, notwithstanding any provision to
the contrary in this Note, the Loan Agreement or in the other Loan Documents,
in no event shall this Note require the payment or permit the collection of
interest in excess of the maximum amount permitted by applicable law.  If any
such excess interest is contracted for, charged or received under this Note, or
in the event that all of the principal balance shall be prepaid, so that under
any of such circumstances the 




<PAGE>   38
amount of interest contracted for, charged or received on the principal balance
shall exceed the maximum amount of interest permitted by applicable law, then
in such event (i) the provisions of Section 1.04(d) of the Loan Agreement shall
govern and control, (ii) neither the Borrower nor any other person or entity
now or hereafter liable for the payment thereof shall be obligated to pay the
amount of such interest to the extent that it is in excess of the maximum
amount of interest permitted by applicable law, (iii) any such excess which may
have been collected shall be either applied as a credit against the then unpaid
principal balance or refunded to the Borrower, at the option of the Lender, and
(iv) the effective rate of interest shall be automatically reduced to the
maximum lawful contract rate allowed under applicable law as now or hereafter
construed by the courts having jurisdiction thereof.  Without limitation of the
foregoing, all calculations of the rate of interest contracted for, charged or
received under this Note which are made for the purpose of determining whether
such rate exceeds the maximum lawful contract rate, shall be made, to the
extent permitted by applicable law, by amortizing, prorating, allocating and
spreading in equal parts during the period of the full stated term of the
indebtedness evidenced hereby, all interest at any time contracted for, charged
or received from the Borrower or otherwise by the Lender in connection with
such indebtedness; provided, however, that if any applicable state law is
amended or the law of the United States of America preempts any applicable
state law, so that it becomes lawful for the Lender to receive a greater simple
interest per annum rate than is presently allowed, on the effective date of
such amendment or preemption as the case may be, the lawful maximum hereunder
shall be increased to the maximum simple interest per annum rate allowed by the
higher of the amended state law or the law of the United States of America.

                                    SECURITY

         2.1     This Note is the secured promissory note issued under and

                 (ii)   any change in the time, manner or place of payment of,
         or in any other term of, all or any of the Obligations, or any other
         amendment or waiver of or any consent to departure from the Loan
         Agreement or the Note;

                 (iii)  any other circumstance which might otherwise constitute
        a defense available to, or a discharge of, the Borrower in respect of
        the Obligations or the Guarantor in respect of this Guaranty.

         (b)  This Guaranty shall continue to be effective or be reinstated, as
the case may be, if at any time any payment of any of the Obligations is
rescinded or must otherwise be returned by the Lender upon the insolvency,
bankruptcy or reorganization of the Borrower or otherwise, all as though such
payment had not been made.

         SECTION 3. Waiver.  The Guarantor hereby waives promptness, diligence,
notice of acceptance and any other notice with respect to any of the
Obligations and this Guaranty and any requirement that the Lender or any other
person exhaust any right or take any action against the Borrower or any other
person or entity or any collateral.  This is a guaranty of payment and not of
collection only.

         SECTION 4. Subrogation.  The Guarantor will not exercise any rights
which it may acquire by way of subrogation under this Guaranty, by any payment
made hereunder or otherwise, until all the Obligations shall have been paid in
full.  If any amount shall be paid to the Guarantor on account of such
subrogation rights at any time when all the Obligations shall not have been
paid in full, such amount shall be forthwith paid to the Lender to be credited
and applied against the Obligations.  If (i) the Guarantor shall make payment
to the Lender, of all or any part of the Obligations and (ii) all the
Obligations shall be paid in full, the Lender will, at the Guarantor's request,
execute and deliver to the Guarantor appropriate documents, without recourse
and without representation or warranty, transferring to the Guarantor any and
all rights the Lender, may have against the Borrower or necessary

<PAGE>   42
to evidence the transfer by subrogation to the Guarantor of any interest in the
Obligations resulting from such payment by the Guarantor.

         SECTION 5. Payments Free and Clear of Taxes, Etc.  (a)  All sums
payable by the Guarantor under this Guaranty, whether of principal, interest,
fees or otherwise, shall be paid in full without set-off or counterclaim and in
such amounts as may be necessary in order that all such payments (after
deduction or withholding for or on account of any present or future taxes,
levies, imposts, duties or other charges of whatsoever nature imposed by any
Governmental Agency or taxing authority thereof, other than any tax or fee on
or measured by the net income of the Lender; collectively the "Taxes") shall
not be less than the amounts otherwise specified to be paid under this
Guaranty.

         (b)  A certificate as to any additional amounts payable to the Lender
under this Section 5 submitted to the Guarantor by the Lender shall show in
reasonable detail the amount payable and the calculations used to determine in
good faith such amount and shall be deemed prima facie correct.

         (c)  With respect to each deduction or withholding for or on account
of any Taxes, the Guarantor shall promptly furnish to the Lender such
certificates, receipts and other documents as may be required (in the
reasonable judgment of the Lender) to establish any income tax credit to which
any of the Lender may be entitled.

         SECTION 6. APPLICABLE LAW AND JURISDICTION.  (a)  THIS GUARANTY
(INCLUDING, BUT NOT LIMITED TO, THE VALIDITY AND ENFORCEABILITY HEREOF) SHALL

represents and warrants as follows:

         (a)  It is a corporation duly incorporated, validly existing and in
good standing under the laws of the State of Texas, duly qualified to do
business wherever its business or ownership of property requires it to be so
qualified.

         (b)  The execution, delivery and performance by the Guarantor of this
Guaranty and any other documents contemplated herein and the completion of all
other transactions herein contemplated are within the Guarantor's corporate

<PAGE>   44
and represents the valid and binding obligation of the Guarantor, enforceable
in accordance with its terms and will not result in the Guarantor's liabilities
(including the maximum amount of liabilities that may be reasonably expected to
result from all contingent liabilities and giving effect to rights of
contribution and subrogation) exceeding the fair market value of its assets.
The enforceability of this Guaranty, however, is subject to all applicable
bankruptcy, insolvency, reorganization, moratorium and other laws affecting the
rights of creditors generally and to general equity principles.

        (d)  The legality, validity, enforceability or admissibility of this

        (e)  There are no pending, or to the best of the Guarantor's knowledge,

interest under the Borrower's Note is hereby fully and completely subordinated
by the Guarantor to the repayment by the Borrower of all amounts due to the
Lender under the Loan Agreement.

        SECTION 9.   The Loan Agreement and the Note.  The Guarantor hereby
acknowledges receipt of the Loan Agreement and the Note in execution form and
hereby consents and agrees to the Loan Agreement and the Note and to all the
terms and provisions thereof.

instance and for the specific purpose for which given.

notice in writing given to the other parties to this Agreement.

         SECTION 12.  No Waiver; Remedies.  No failure on the part of the
Lender to exercise, and no delay in exercising, any right hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right hereunder preclude any other or further exercise thereof or the exercise
of any other right.  The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

         SECTION 13.  Continuing Guaranty.  This Guaranty is a continuing
guaranty and shall (i) remain in full force and effect until payment in full of
the Obligations and payment in full of all other amounts due under this

compliance therewith.

         Section 1.5  Operation of the Vessels.  The Mortgagor will not cause
or permit the Vessels to be operated in any manner contrary to applicable law
or regulation, or in any manner not permitted by the Loan Agreement or by any
insurances required thereby and hereby, will not engage in any unlawful trade,
violate any applicable law or carry any cargo that will expose the Vessels to
penalty, forfeiture or capture and will not do, or suffer or permit to be done,
anything which can or may injuriously affect the documentation of the Vessels
under the laws and regulations of the United States of America.  Mortgagor
shall keep the operation of the Vessels within the permitted navigational
limits set forth in the trading warranties of the policies of insurance
covering each of the Vessels and in any case will not operate the Vessels, or
permit the Vessels to be operated, in any area where such insurance would not
be fully applicable and enforceable with respect to each of the Vessels and its
operation.

         Section 1.6  Claims Taxes Fees Etc. The Mortgagor will pay and
discharge or cause to be paid and discharged all claims against, and fees,
taxes, assessments, governmental charges, fines and penalties imposed on each
Vessel, its cargoes or any income therefrom when due and payable, except those
claims, fees, taxes, assessments, governmental charges and penalties being
contested in good faith by appropriate proceedings for which adequate reserves
are being maintained.

         Section 1.7  Liens.  Neither the Mortgagor, any charterer, the master
of any Vessel nor any other person has or shall have any right, power or
authority to create, incur or permit to be placed or imposed or continued upon
any Vessel, its freights, profits or hires, any lien, security interest,
encumbrance or charge whatsoever other than the lien of this Mortgage and liens
for wages of the crew, including the master of such Vessel, for wages of
stevedores when employed directly by a person listed in Section 31341 of Title
46 of the United States Code, or for general average or salvage (such lien

Mortgage in safekeeping with each Vessel's papers at the principal office of
Mortgagor and on demand to exhibit the same to any person having business with
such Vessel, or to any representative of Mortgagee.  Mortgagor shall also place

Under the terms of said First Preferred Fleet Mortgage neither Owner, any

therein any lien whatsoever other than liens for wages of the crew, for wages
of stevedores when employed directly by a person listed in Section 31341 of
Title 46 of the United States Code, or for general average or salvage."

         Such notice shall be amended at the sole cost and expense of
Mortgagor, upon request of Mortgagee, to reflect the identity of any successor
Mortgagee.

         Section 1.8  Exhibit of Mortgage.  The Mortgagor shall exhibit and
shall require that any other person having custody or control of such Vessel to
exhibit a copy of this Mortgage to any person having business with the Vessel
which might give rise to a maritime lien upon such Vessel or otherwise be
deemed a sale, conveyance, mortgage or lease thereof and, on demand, to any
representative of the Mortgagee.

         Section 1.9  Removal of Liens.  The Mortgagor will not suffer to be
continued any lien (other than Permitted Liens but only to the extent permitted
under Subsection 1.7), encumbrance or charge on any Vessel other than this
Mortgage, and in due course and in any event within thirty (30) days after the
same shall become due and payable, (except for those claims or demands being
contested in good faith by appropriate proceedings for which adequate reserves
are being maintained), will pay or caused to be discharged or make adequate
provisions for the satisfaction or discharge of all claims or demands secured
by any lien, charge or encumbrance on such Vessel and will cause the Vessel to

Vessel or if any Vessel shall be attached, levied upon or taken into custody by
virtue of any proceeding in any court or tribunal or by any government or other
authority, the Mortgagor shall promptly notify the Mortgagee thereof by
telecopier, confirmed by overnight letter addressed to the Mortgagee, and
within three (3) Business Days after any such libel, levy, attachment or taking
into custody will cause any such Vessel to be released and will promptly notify
the Mortgagee of such release in the manner aforesaid.

         Section 1.11  Maintenance and Classification of Vessel.  The Mortgagor
will at all times and without cost or expense to the





                                       5
<PAGE>   53
Mortgagee (a) maintain each Vessel and its machinery in such condition and
repair as will keep the Vessel entitled to the highest classification in the
American Bureau of Shipping, or other classification society of like standing
approved in writing by the Mortgagee for such vessels, (b) keep each Vessel,
its machinery, boilers, appurtenances and spare parts in a good state of
repair, wear and tear and depreciation excepted, and in efficient operating
condition in accordance with good commercial maintenance practices employed in
the offshore oil and gas contract drilling industry, (c) keep each Vessel
tight, staunch, strong and in all respects seaworthy, in so far as due
diligence can make it, (d) maintain each Vessel with full unexpired
classification and other required certificates and (e) furnish prior to
December 1 of each year to the Mortgagee, a written statement of the
classification society that any classification referred to in (a) above is in
effect.  All maintenance and repairs will be made in a good and workmanlike
manner by persons of appropriate skill and experience whose work will not
adversely affect the service life or marketability of each Vessel.  All
repairs, parts, mechanisms, devices, replacements, improvements, changes,
additions and alterations to the Vessels shall immediately and without further
act, become part of the Vessels and subject to this Mortgage.  Mortgagor shall
promptly furnish to the Mortgagee copies of each damage survey with respect to
damage to any Vessel where the survey does not specifically quantify the cost
of total damages or where the survey states total damage in excess of USD
100,000.00.

         Section 1.12  Changes in Vessels.  The Mortgagor will not make, or
permit to be made, any material change in the structure or type of any Vessel
or in its rig, unless it shall have received the prior written consent thereto
of the Mortgagee.

         Section 1.13  Inspection.  The Mortgagor at all times shall afford the
Mortgagee or its authorized representatives full and complete access to the
Vessels for the purpose of inspecting or surveying the same and their papers
and, at the request of the Mortgagee, the Mortgagor shall deliver for
inspection copies of any and all contracts and documents relating to each
Vessel, whether on board or not and shall cause any charterer to comply
herewith during the term of any charter to the maximum extent permitted
thereunder.

         Section 1.14  Change of Flag or Port of Documentation.  The Mortgagor
will not change the flag or port of documentation of the Vessels without the
prior written consent of the Mortgagee and the payment by the Mortgagor of all
expenses of registration or re-registration of this Mortgage.  Such consent may
be denied or withheld for any reason or for no reason, except that Mortgagee
shall not unreasonably withhold its consent to a change in the port of
documentation, although reasonable conditions may be attached to such consent.
Any such written consent to any one transfer or change of flag or port of
documentation shall not be construed as





                                       6
<PAGE>   54
a waiver of these provisions with respect to any other or subsequent proposed
transfer or change of flag or port of documentation.

         Section 1.15  Sale or Other Disposition of Vessels.

         (a)  Except as provided below, the Mortgagor will not sell, charter,
mortgage, transfer or in any other way dispose of all or any part of or
interest in any Vessel without the prior written consent of the Mortgagee.  Any
sale, mortgage, charter, transfer or other disposition of all or any part of or
interest in any Vessel shall be subject to the provisions of this Mortgage and
the lien hereof.  The Mortgagor will not charter any Vessel to, or permit any
Vessel to serve under any contract of affreightment with, a person included
within the definition of "designated foreign country" or a "national" of a
"designated foreign country" in the "Foreign Assets Control Regulations" or
"Cuban Assets Control Regulations" of the United States Treasury Department, 31
C.F.R. Chapter V, as amended, within the meaning of said regulations or of any
regulation, interpretation or ruling issued thereunder.

         (b)  Mortgagor shall not enter into any charter for any Vessel in
excess of twelve months (inclusive of all extension and renewal opt-on periods)
without the prior written consent of the Mortgagee, and in the case where such
consent is given, not without providing Mortgagee a copy thereof and without
first obtaining the written agreement of such charterer in each case to the
collateral assignment by Mortgagor to Mortgagee of a first priority lien and
security interest in the charter, charter hire and earnings of such charter,
such consent to be in form acceptable to Mortgagee.  Mortgagor undertakes and
covenants that any such charter shall contain a provision prohibiting the
charterer and any other persons from incurring or acquiring any lien on any
Vessel.

         Section 1.16  Requisition of Title or Use. In the event that the title
to or ownership of any Vessel, or the use of any Vessel (whether on a bareboat,
time or voyage charter basis or any other basis), shall be requisitioned,
purchased or taken by, or any Vessel shall be seized by or forfeited to any
government of any country or any department, agency or representative thereof,
pursuant to any present or future law, proclamation, decree, order or
otherwise, or by any other person or persons, whether or not acting under color
of governmental authority, the compensation, purchase price, reimbursement or
award for such requisition, purchase, seizure, forfeiture or other taking of
such title, ownership or use shall forthwith be and become payable to the
Mortgagee, who shall be entitled to receive the same and shall apply it as
provided in Section 1.05(c) of the Loan Agreement.

         Section 1.17  Notice of Loss Requisition or Damage. In the event of (a)
the disappearance or actual or constructive loss of any Vessel, (b) any event
referred to in Section 1.16 hereof with





                                       7
<PAGE>   55
respect to any Vessel, or (c) any casualty, accident or damage to any Vessel in
excess of USD 100,000.00, the Mortgagor will give written notice thereof
(containing full particulars), within three (3) Business Days of the occurrence
thereof, to the Mortgagee.

         Section 1.18  Insurance.

         I. Form and Amount.

         I(A). Hull & Machinery Insurance. At its own expense, Mortgagor shall
maintain or cause to be maintained with financially sound and reputable
insurers satisfactory to Mortgagee all risk equivalent marine hull and
machinery insurance (and, if necessary to satisfy the proviso of this
subparagraph, policies of increased value insurance) and war risk hull and
machinery insurance covering confiscation, nationalization, expropriation and
seizure on an agreed value basis on each Vessel against loss, damage, fire and
such other perils and in such amounts as are usually maintained on vessels
engaged in the same or a similar business under blanket fleet policies with
respect to vessels of like size, character and marine activity; provided,
however, that in no event shall the amount of such insurance, subject to such
deductible, if any, as permitted by Mortgagee, at any time be less than the
greater of (a) the Fair Market Value (as defined in the Loan Agreement) or (b)
the amount of the outstanding principal, interest and all other obligations
covered by this Mortgage.

         Such insurance shall name the Mortgagee, Mortgagor and other
interested persons as insureds as their respective interests may appear, but
(subject only to paragraph II of Subsection 1.18) shall be payable solely to
Mortgagee for further disbursement by it to the other insureds as their
interests may appear and shall be applied as set forth in Subpart II of this
Section 1.18.

         Unless a Default hereunder shall have occurred and is continuing
hereunder, Mortgagee consents to a deductible of USD 250,000.00 per incident
with respect to policies required under this Subsection I(A).

         I(B).  Liability Insurance.  At its own expense, Mortgagor shall
maintain entries with financially sound and reputable insurers or protection
and indemnity associations satisfactory to the Mortgagee protection and
indemnity, collision, tower's liability including crew, cargo, contractual
liabilities, and removal of wreck insurance and protection and indemnity war
risk insurance protecting the interests of Mortgagor and Mortgagee against
liability for property damage to third persons (including liability to any
governmental authority or other person with respect to pollution liability) and
personal injury or death to any person arising out of the maintenance, use,
operation and ownership of the Vessels, cargo damage or loss, contractual
liability and wreck removal in such amounts as are usually carried by persons





                                       8
<PAGE>   56
engaged in the same or similar businesses; provided, however, that in no event
shall the amount of such insurance per person and per occurrence (subject to
such deductible, if any, permitted by Mortgagee) be less than the customary
amount of coverage available on the market from time to time with respect to
vessels of the same type, age and trade as the Vessels and acceptable to the
Mortgagee.  Such liability insurance shall name each of the Mortgagee,
Mortgagor and other interested persons as additional insureds, as their
respective interests may appear, but the proceeds of such policies shall be
payable to the person actually suffering the loss in respect of which such
proceeds are payable provided, however, that if Mortgagee shall have first
notified the underwriters or brokers that a Default hereunder has occurred then
all such proceeds to which the Mortgagor would have otherwise been entitled
shall be thereafter payable to Mortgagee for distribution to itself and others
as their interests may appear as hereinafter set forth or otherwise with the
consent of Mortgagee in each case.

         I(C).  Other Insurance.  At its own expense, the Mortgagor shall, at
all times during which the Vessels are operating within the jurisdiction of the
United States of America, maintain

                (i)       insurance or post bond or maintain approved evidence
         of financial responsibility with respect to the Vessels to cover the
         actual cost of removal of discharged oil for which the Mortgagor or
         the Vessels may be held strictly liable (or held liable due to
         negligence of the Mortgagor or any other person) under the Clean Water
         Act of 1977, the Oil Pollution Act of 1990 or the Outer Continental
         Shelf Lands Act, or under any other federal or state law which, in the
         future, may apply to the Vessels or to the Mortgagor; and the
         Mortgagor shall maintain insurance or post bond or maintain approved
         evidence of financial responsibility covering similar pollution risks
         or liabilities incident thereto under any law, regulation or judicial
         decision of any foreign jurisdiction or jurisdictions or political
         subdivision thereof applicable to the Mortgagor, the Vessels or their
         operations;

                (ii)      such workmen's compensation or longshoremen's and
         harbor workers' insurance as shall be required by applicable law,
         including endorsements for Outer Continental Shelf operations,
         borrowed servant, voluntary compensation and in rem claims;

                (iii)      insurance (with a limit of USD 5,000,000 per
         occurrence) naming the Mortgagor and the Mortgagee assureds and loss
         payees, as their interests may appear, against contingent Operator's
         Extra Expense ("O.E.E.") liabilities in connection with operations
         conducted by the Vessels with respect to Vessels operating under a
         drilling contract with a financially responsible operator acceptable
         to the Mortgagee that indemnifies against such "O.E.E." arising out of
         blowout





                                       9
<PAGE>   57
         (above and below ground), cratering, redrilling/recompletion, cost of
         control, clean-up, containment seepage, pollution, spillage or leakage
         in connection with operations conducted by any Vessel, in form and
         substance satisfactory to the Mortgagee, and third party liabilities
         ("T.P.L.") that may be assumed by a contract which is legally
         enforceable and in form and substance satisfactory to the Mortgagee.
         Deductibles or self-insured retentions shall not exceed USD 250,000
         ("O.E.E.")/ ("T.P.L.") and shall be for the account of the Mortgagor;

                 (iv)     excess seepage, pollution, clean-up and containment
         liability coverage in the amount of USD 50,000,000 in respect of
         offshore operations in excess of and following the seepage, pollution,
         clean-up and containment liability coverage recited in Subsection 
         (iii) above; and

                 (v)      mortgagee's interest insurance or breach of warranty
         endorsement in favor of the Mortgagee with such underwriters and under
         forms of policies approved by the Mortgagee in an amount equal to at
         least 125% of the Loan.

         II.   Application of Proceeds. All policies of insurance required under
this Section 1.18 shall be placed through first-class marine brokers acceptable
to Mortgagee and shall name the Mortgagor and Mortgagee as Additional Insureds.
All policies maintained under Subsection I above shall also name the Mortgagee
as a loss payee for all hull and machinery policies, and, in the case of
policies procured under Subpart I(A) hereof, shall provide that all payments in
respect of loss or damage shall be made solely to the Mortgagee for all amounts
in excess of USD 100,000.00 and that upon the occurrence and continuance of a
Default hereunder, all proceeds shall be payable solely to Mortgagee.  Any
insurance recoveries under any policies to which the Mortgagee shall be so
entitled shall be applied as provided in Section 1.05(c) of the Loan Agreement.
Until a Default has occurred, the Mortgagee and the Mortgagor shall cooperate
in adjusting any claim with the underwriters of insurances for the Vessels and
underwriters may rely on any agreement reached with the Mortgagor as binding
both the Mortgagee and the Mortgagor.  Following the occurrence of a Default,
the Mortgagee and the Mortgagor shall continue to cooperate to adjust any claim
but only the Mortgagee shall have the power to agree any adjustment with
underwriters on behalf of the Vessels, the Mortgagor and itself.

         III.  Constructive Total Loss. In the event of an accident, occurrence
or event resulting in a constructive total loss of any Vessel, the Mortgagee
shall have the right to claim for a constructive total loss of the Vessel and
to require that Mortgagor declare such to be a constructive total loss, and if
both (1) such claim is accepted by all underwriters under all policies then in
force as to the Vessel under which payment is due for total loss





                                       10
<PAGE>   58
and (2) payment in full is made in cash under such policies, then the Mortgagee
shall have the right at its election, to abandon the Vessel to the underwriters
under such policies, free from the lien of this Mortgage and apply the proceeds
of such insurance as provided in Section 1.05(c) of the Loan Agreement.

         IV.   Agreed or Compromised Total Loss. In the event of an accident,
occurrence or event of damage to any Vessel, the Mortgagee shall have the right
in its discretion to enter into an agreement or compromise with underwriters
providing for an agreed or compromised total loss of the Vessel.

         V.    Carriers; Approvals. All insurance required under this Section
shall be placed and kept with the United States Government or with American,
British, or other insurance companies, underwriters' associations, clubs or
underwriting funds approved by the Mortgagee.  Any approval of a policy under
this Section 1.18 shall be effective until the end of the policy period or
until thirty (30) days after the Mortgagee shall notify the Mortgagor of the
desired change in the form and/or amount thereof, whichever shall first occur.
Notwithstanding the foregoing, Mortgagee may require changes on shorter notice
if such changes are necessary or desirable to comply with requirements of or
insure against liabilities created or increased by any change, modification,
amendment in the law (including judicial or administrative decisions),
regulations, rules, policies or practices of the United States government or
the government of any state, territory, possession thereof or of any other
place where the Vessel may be operating or whose laws may apply.

         VI.   Taking, Requisition, etc. During the continuance of a taking,
requisition or charter of the use of any Vessel by the United States
Government, with the prior written consent of the Mortgagee, the provisions of
this Section shall be deemed to have been complied with in all respects as to
any Vessel if the United States Government shall have agreed, pursuant to an
agreement in form and substance satisfactory to the Mortgagee, to reimburse the
Mortgagee and the Mortgagor for loss or damage resulting from the risks
indicated in subsection I of this Section. In the event of any taking,
requisition, charter or loss of any Vessel contemplated by this paragraph the
Mortgagor shall promptly furnish to the Mortgagee an Officers Certificate
stating that such taking, requisition, charter or loss has occurred and, if
such is the case, that the United States Government has agreed to reimburse the
Mortgagee and the Mortgagor for loss or damage resulting from the risks covered
pursuant to the requirements of Subpart I of this Section 1.18.

         VII.  Additional Provisions.    All insurance required under this
Section 1.18 shall, unless otherwise first agreed in writing by the Mortgagee,
provide that (1) there shall be no recourse against the Mortgagee for the
payment of premiums, supplemental or





                                       11
<PAGE>   59
back calls or commissions or warranties or representations to underwriters, (2)
if such insurance provides for the payment of club calls, assessments or
advances, there shall be no recourse against the Mortgagee for the payment
thereof, (3) at least thirty (30) days' prior written notice of any
cancellation, reduction in amount or change in coverage or other material
change of such insurance shall be given to the Mortgagee by the insurance
underwriters, (4) the interests of the Mortgagee shall be continued insured
regardless of any breach of or violation by Mortgagor or any other insured of
any warranties, declarations or conditions contained in such insurances, (5) no
insurance shall be excess over other coverage but shall be primary insurance
and shall not require any contribution from any excess insurance on any Vessel
which may be carried by Mortgagee, (6) no insurance shall be invalidated by any
assignment of any charters of any Vessel, and (7) the insurers agree to advise
Mortgagee promptly in writing of any default in the payment of any premium and
of any other act or omission of which such insurer has knowledge which might
invalidate or render unenforceable, in whole or in part, any such policy.  The
policies shall provide for severability of interest as though separate policies
were issued to each additional insured except with respect to the limits of
liability.

         The Mortgagor shall not, without the prior written consent of the
Mortgagee, do any act, nor voluntarily suffer nor permit any act to be done,
whereby any insurance required by this Section shall or may be suspended,
impaired or defeated, or suffer or permit any Vessel to engage in any voyage or
any activity not permitted under policies of insurance satisfactory to the
Mortgagee in all respects for such voyage or the engaging in of such activity.

         Section 1.19 Reimbursement of Mortgagee.  In the event that Mortgagor
shall fail to obtain or maintain insurance in accordance with the provisions of
this Mortgage, Mortgagee shall have the right to obtain, and pay the premiums
on, such insurance as Mortgagee reasonably deems necessary.  The Mortgagor
shall reimburse the Mortgagee on demand, with interest at the rate (described
in Section 1.04(c) of the Loan Agreement) for any and all expenditures which
the Mortgagee may from time to time make, lay out or expend in providing
protection in respect of insurance, discharge or purchase of any liens, taxes,
dues, assessments, governmental charges, fines and penalties imposed, repairs,
attorneys' fees and other matters as the Mortgagor is obligated herein to
provide, but fails to provide.  Such obligation of the Mortgagor to reimburse
the Mortgagee, together with interest as provided above, shall be an additional
indebtedness due from the Mortgagor, secured by this Mortgage, and shall be
payable by the Mortgagor on demand.  The Mortgagee, though privileged so to do,
shall be under no obligation to the Mortgagor or to any other person to make
any such expenditures, nor shall the making thereof relieve the Mortgagor of
any Default in that respect.

         Section 1.20  Reports.  Prior to the date hereof and concurrently with
each renewal or replacement of each policy or entry thereafter, Mortgagor shall
furnish to the Mortgagee an original certificate of insurance or a report by a
nationally recognized first class marine insurance broker acceptable to the
Mortgagee, describing in reasonable detail the insurance then carried and
maintained on and with respect to the Vessels and certifying that such
insurance complies with the terms hereof and certifying that the insurances are
in the form, cover the risks and are in the amounts determined in accordance
with Section 1.18 of this Mortgage, and that, in the opinion of such firm, the
insurance then carried and maintained complies with the terms of said Section
1.18.  Mortgagor shall obtain for the benefit of Mortgagee the undertaking of
Mortgagor's insurance agent or broker to promptly advise the Mortgagee in
writing of any act or omission of which such agent or broker has knowledge
which might invalidate or render unenforceable, in whole or in part, any such
policy.

                  ARTICLE 3. REMEDIES: APPLICATION OF PROCEEDS

         Section 3.1  Sale. etc.  If a Default specified in Subsection 2.1(a)
above shall occur as a result of an Event of Default occurring under Article
IV, subsections H or I of the Loan Agreement, then, and in any such event, the
principal amount of the Note, together with accrued interest thereon and all
other obligations shall become immediately due and payable without any notice
or other action by the Mortgagee, or if any other Default shall occur and be
continuing, then, and in any such event, the Mortgagee may, by notice of
default given to the Mortgagor, declare the principal amount of the Note,
together with accrued interest thereon and any other amounts due in accordance
therewith and all other obligations to be forthwith due and payable, whereupon
all such amounts shall become immediately due and payable without presentment,
demand, protest or other notice of any kind, all of which are hereby expressly
waived.  During the continuance of any Default, Mortgagee shall have the right
to pursue and enforce any of its rights and remedies under the Loan Agreement
and any other Loan Document and, in addition, Mortgagee may do any one or more
of the following as it may elect:

         (a)     Exercise all the rights and remedies in foreclosure and
otherwise given to mortgagees by the provisions of the U.S. Code, Tit. 46, Ch.
313, as amended, or other applicable law including the laws of any other
applicable jurisdiction;

         (b)     Bring suit at law, in equity or in admiralty or initiate and
prosecute such other judicial, extra-judicial, or administrative proceedings as
it may consider appropriate to recover any and all sums due, or declared due,
on the Note, and all other obligations due, with the right to enforce payment
of said sums against any assets of the Mortgagor, whether they are covered by
this Mortgage or otherwise;

         (c)     Take possession of the Vessels with or without legal
proceedings, at any place where it or they may be found; and the Mortgagor or
any person in possession of the Vessels, forthwith upon request by the
Mortgagee, as mortgage creditor, shall deliver possession to the Mortgagee, and
the Mortgagee shall have the right, without being responsible for loss or
damage, to lay up, hold, charter, lease, operate or otherwise use the Vessels
for such period and under such conditions as it may deem most expedient for its
interest, and demand, collect and retain all hire, freights, earnings, issues,
revenues, income, profits, returns, premiums, salvage awards or recoveries,
recoveries in general average, and all other sums due or to become due in
respect of the Vessels or in respect of any insurance thereon from any person
whomsoever, accounting only for net profits, if any, arising from such use and
charging against all receipts from such use or from the sale of the





                                       14
<PAGE>   62
Vessels by court proceedings or pursuant to subsection (d) below, all costs,
expenses (including without limitation attorneys' fees and disbursements),
charges, damages or losses by reason of such use; and if at any time the
Mortgagee shall avail itself of the right herein given to it to take the
Vessels and shall take them, the Mortgagee shall have the right to dock the
Vessels at any dock, pier or other premises owned or leased by the Mortgagor
without charge, or at any other place at the cost and expense of the Mortgagor;

         (d)     Take and enter into possession of the Vessels, at any time,
wherever the same may be, without legal process, and if it seems desirable to
the Mortgagee without being responsible for loss or damage, sell it at any
place or places and at such time or times as the Mortgagee may specify, at
public or private sale, by sealed bids or otherwise, on such terms and
conditions as the Mortgagee deems best, free of any claim, commitment or
encumbrance, regardless of the nature thereof, in favor of the Mortgagor and,
except as provided by law, in favor of any other person, upon advance notice of
ten (10) consecutive days published in any newspaper authorized to publish
legal notices of that kind in the port of documentation and the places of sale
of the Vessels and by sending notice of each such sale at least fourteen (14)
days prior to the date fixed for such sale, by mail, to the Mortgagor. In the
event that the Vessels shall be offered for sale by private sale, no newspaper
publication of notice shall be required, nor notice of adjournment of sale.
Sale may be held at such place and at such time as the Mortgagee by notice may
have specified, or may be adjourned by the Mortgagee from time to time by
announcement at the time and place appointed for such sale or for such
adjourned sale, and, without further notice or publication the Mortgagee may
make any such sale at the time and place to which the same shall be so
adjourned; and any sale may be conducted without bringing the Vessels to the
place designated for such sale and in such manner as the Mortgagee may deem to
be for its best advantage, and the Mortgagee may become the purchaser at any
public sale, and shall have the right to credit on the purchase price any and
all sums of money due to the Mortgagee under the Note, or otherwise due to the
Mortgagee hereunder or under the Loan Agreement, the Guaranty or under any
other instrument evidencing any obligation.

         Section 3.2  Finality of Sale.  A sale of the Vessels made in
pursuance of this Mortgage, whether under the power of sale hereby granted or
any judicial proceedings, shall operate to divest all right, title and interest
of any nature whatsoever of the Mortgagor therein and thereto, and shall bar
the Mortgagor, its successors and assigns, and all persons claiming by, through
or under them. No purchaser shall be bound to inquire whether notice has been
given or whether any Default has occurred, or as to the propriety of the sale,
or as to application of the proceeds thereof.  In case of any such sale, any
purchaser who is the holder of this Mortgage shall be entitled, for the purpose
of making settlement or payment for





                                       15
<PAGE>   63
the Vessels, to apply the balance due under this Mortgage or a part thereof as
part or all of the purchase price to the extent of the amount remaining due and
unpaid.  At any such sale, the holder of this Mortgage may bid for and purchase
the Vessels and upon compliance with the terms of sale may hold, retain and
dispose of the Vessels without further accountability.  At any such sale, the
Mortgagee may bid for the purchase of the Vessels and upon compliance with the
terms of sale may hold and retain and dispose of the Vessels without further
accountability therefor.

         Section 3.3  Powers and Rights of Mortgagee upon Occurrence of Default.

         (a)  Sale.  For the purpose of Sections 3.1 and 3.2 the Mortgagor does
hereby irrevocably appoint the Mortgagee and its successors and assigns the
true and lawful attorneys-in-fact of the Mortgagor, in its name and stead, to
make the necessary transfers of the Vessels, and for that purpose the Mortgagee
may execute the necessary instruments of assignment and transfer (including
bills of sale), the Mortgagor hereby ratifying and confirming all that its said
attorney shall lawfully do by virtue hereof.  Nevertheless, the Mortgagor, if
so requested by the Mortgagee, shall ratify and confirm any sale of the Vessels
by executing and delivering to the purchaser thereof such proper bills of sale,
conveyances, instruments of transfer and releases as may be designated in such
request.

         (b)  Revenues and Proceeds of the Vessels. The Mortgagee is hereby
irrevocably appointed attorney-in-fact of the Mortgagor, upon the happening and
during the continuation of any Default, in the name of the Mortgagor to demand,
collect, receive, compromise and sue for, so far as may be permitted by law,
all drilling contract revenues, freights, hire, earnings, issues, revenues,
income and profits of the Vessels, and all amounts due from underwriters under
any insurance thereon as payment or losses or as return premiums or otherwise,
salvage awards and recoveries, recoveries in general average or otherwise, and
all other sums due or to become due in respect of the Vessels or in respect of
any insurance thereon from any person whomsoever, and to make, give and execute
in the name of the Mortgagor acquittances, receipts, releases or other
discharges for the same, whether under seal or otherwise, and to endorse and
accept in the name of the Mortgagor all checks, notes, drafts, warrants,
agreements and all other instruments in writing with respect to the foregoing,
the Mortgagor hereby confirming and ratifying the same.

         (c)  Additional Rights.  The Mortgagor covenants and agrees that in
addition to any and all other rights, powers and remedies elsewhere in this
Mortgage granted to and conferred upon the Mortgagee, and including, without
limitation, in any suit to enforce any of its rights, powers or remedies, if a
Default shall have occurred and be continuing and shall not have been waived by





                                       16
<PAGE>   64
the Mortgagee, the Mortgagee shall be entitled as a matter of right and not as
a matter of discretion (i) to the appointment of a receiver or receivers of the
Vessels and collection of the freights, hire, earnings, issues, revenues,
income and profits due or to become due arising from any operation of the
Vessels, and any receiver or receivers so appointed shall have full right and
power to use and operate the Vessels, and (ii) to a decree ordering and
directing the sale and disposal of the Vessels, and the Mortgagee may become
the purchaser at such sale and shall have the right to credit on the purchase
price any and all sums of money due under the Note or otherwise due to the
Mortgagee hereunder or under the Loan Agreement, the Guaranty or under any
other Loan Document.  The Mortgagee shall not be required to have the Vessels
marshalled (upon any sale of the Vessels pursuant to this Mortgage or
otherwise) or be required to realize on any other collateral prior to
realization on the Vessels.

         Section 3.4  Restoration of Position.  In case the Mortgagee shall
have proceeded to enforce any right, power or remedy under this Mortgage by
foreclosure, entry or otherwise, and such proceedings shall have been
discontinued or abandoned for any reason or shall have been determined
adversely to the Mortgagee, then and in every such case the Mortgagor and the
Mortgagee shall be restored to their former positions and rights hereunder with
respect to the property subject or intended to be subject to the Mortgage, and
all rights, remedies and powers of the Mortgagee shall continue as if no such
proceedings had been taken.

         Section 3.5  Application of Proceeds.  The proceeds of any sale and
net earnings derived from the operation, use, charter, or any other employment
of the Vessels by the Mortgagee, as mortgage creditor, and within any of the
powers and authority above given, as well as the proceeds of any judgment which
the Mortgagee may obtain by reason of the breach or failure to perform any of
the terms of this Mortgage, as well as the proceeds of any claim for damage
received by the Mortgagee while exercising the powers and the authorities above
given, shall be applied by Mortgagee as provided in the Loan Agreement.

         In the event the proceeds and the net earnings referred to in this
Section 3.5 should be insufficient to pay the sum total of the Mortgagor's
obligations to the Mortgagee, then the Mortgagee, as mortgage creditor, shall
have the right to collect and to receive from the Mortgagor, or from any other
person or persons who may be chargeable in respect thereof, such amount as will
fully pay any remaining deficiency with respect to the obligations.  In any
action to enforce the Mortgage whether in rem or in personam, in admiralty, in
equity or at law Mortgagor hereby waives any right to trial by jury.

         Section 3.6  No Transfer in Violation of Shipping Act.
Notwithstanding any other provision herein to the contrary, no sale, charter,
transfer or other disposition of any Vessel or any interest therein may be made
to any entity not a citizen of the United States within the meaning of Section
2 of the Shipping Act of 1916, as amended, without the approval of the
Secretary of Transportation of the United States.

         Section 3.7  Defeasance.  If the Note shall have been satisfied and
discharged, then this Mortgage and the estate and rights hereunder shall cease,
determine, and become null and void; and the Mortgagee, on the request of the
Mortgagor and at the Mortgagor's cost and expense, shall forthwith cause
satisfaction and discharge of this Mortgage to be entered upon its and other
appropriate records and shall execute and deliver to the Mortgagor such
instruments as may be necessary in the Mortgagor's reasonable opinion to duly
acknowledge the satisfaction and discharge of this Mortgage.

         Section 3.8  Right of Peaceful Enjoyment.  During the term of this
Mortgage and so long as no Event of Default shall have occurred and be
continuing, the Mortgagor shall have full and peaceful enjoyment, use, right to
possession and control of the Vessels.

                     ARTICLE 4. GENERAL POWERS OF MORTGAGEE

         (a)  Arrest or Detention of a Vessel.  In the event that any Vessel
shall be arrested or detained by a Marshal or other officer of any court of
law, equity or admiralty jurisdiction in any country or nation of the world or
by any government or other person, the Mortgagor does hereby authorize and
empower the Mortgagee, from the date of arrest or detention, in the name of the
Mortgagor, or its successors or assigns, to apply for and receive possession of
and to take possession of the Vessel with all the rights and powers that the
Mortgagor, or its successors or assigns, might have, possess or exercise in any
such event; and this power of attorney shall be irrevocable and may be
exercised not only by the Mortgagee but also by its appointee or appointees,
with full power of substitution, to the same extent as if the said appointee or
appointees had been named as one of the attorneys above named by express
designation.

         (b)  Suits. The Mortgagor also authorizes and empowers the Mortgagee
or its appointees or any of them to appear in the name of the Mortgagor, its
successors or assigns, in any court of any country or nation of the world where
a suit is pending against any Vessel because of or on account of any alleged
lien against the Vessel from which the Vessel has not been released and to take
such proceedings as to them may seem proper towards the defense of such suit
and the discharge of such lien, and all expenditures made or incurred by them
or any of them for the purpose of such defense or





                                       18
<PAGE>   66
discharge shall be a debt due from the Mortgagor, its successors and assigns,
to the Mortgagee, and shall be secured by the lien of this Mortgage in like
manner and extent as if the amount and description thereof were written herein.

                              ARTICLE 5. INDEMNITY

         The Mortgagor assumes liability for, and agrees to indemnify and hold
the Mortgagee harmless from, all claims, costs, expenses (including legal
expenses), damages and liabilities arising from or pertaining to this Mortgage
or the ownership, use, possession or operation of the Vessels; provided that
Mortgagor shall have no obligation hereunder with respect to amounts subject to
indemnification between such parties under any agreement of trust between such
parties or for indemnified liabilities arising from the gross negligence or
wilful misconduct of Mortgagee.  The agreements and indemnities contained in
this Article shall survive the maturity or earlier discharge of this Mortgage
and payment in full of the Note.

                          ARTICLE 6. SUNDRY PROVISIONS

         Section 6.1  Cumulative Remedies; No Waiver.  Each and every power and
remedy herein given to the Mortgagee shall be cumulative and shall be in
addition to every other power and remedy herein or now or hereafter existing at
law, in equity, in admiralty or by statute, and each and every power and remedy
whether herein given or otherwise existing may be exercised from time to time
and as often and in such order as may be deemed expedient by the Mortgagee, and
the exercise or the beginning of the exercise of any power or remedy shall not
be construed to be a waiver of the right to exercise at the same time or
thereafter any other power or remedy.  No delay or omission by the Mortgagee in
the exercise of any right or power in the pursuance of any remedy specified in
Article 3 accruing upon any Default hereof shall impair any such right, power
or remedy or be construed to be a waiver of any such Default or an acquiescence
therein; nor shall the acceptance by the Mortgagee of any security or of any
payment of or on account of any part of the indebtedness secured by this
Mortgage or of any payment on account of any past Default be construed to be a
waiver of any right to take advantage of any future Default or of any past
Default not completely cured thereby.

         Section 6.2  Further Assurances. In the event that this Mortgage, or
any provisions hereof, shall be deemed invalid in whole or in part by reason of
any present or future law or any decision of any court having jurisdiction, or
if the documents at any time held by the Mortgagee shall be deemed by the
Mortgagee for any reason insufficient to carry out the rights and powers
granted to the Mortgagee herein, then, from time to time, the Mortgagor will
do, execute, acknowledge and deliver, or cause to be done, executed,
acknowledged and delivered such other and further





                                       19
<PAGE>   67
assurances and documents as in the opinion of the Mortgagee may reasonably be
required in order to more effectively subject the Vessel to the lien of this
Mortgage or more effectively subject the Vessel to the performance of the terms
and provisions of this Mortgage, or to enable this Mortgage continuously to
enjoy the status of a First "Preferred" Mortgage.

         Section 6.3  No Waiver of Preferred Status.  No provision of this
Mortgage shall be deemed to constitute a waiver by the Mortgagee of the
preferred status hereof given by the U.S. Code, Tit. 46, Ch. 313, as amended,
and any provision of this Mortgage which would otherwise constitute such a
waiver shall to such extent be of no force or effect.


         Section 6.4  Survival of Agreements.  All representations, warranties,
covenants and agreements herein contained or made in writing in connection with
this Mortgage shall survive the execution of this Mortgage and shall continue
in full force and effect until all sums secured hereby shall have been paid in
full, and the same shall bind and inure to the benefit of the respective
successors and assigns of the Mortgagor and the Mortgagee.
