                                ---------------
 
    Chiles Offshore LLC, a Delaware limited liability company (the "Company"),
and Chiles Offshore Finance Corp., a special purpose Delaware corporation and a
wholly owned subsidiary of the Company ("Finance" and, together with the
Company, the "Issuers") and the Guarantors (as hereinafter defined) hereby
offer, upon the terms and subject to the conditions set forth in this Prospectus
and the accompanying Letter of Transmittal (which together constitute the
"Exchange Offer"), to exchange $1,000 principal amount of registered 10% Senior
Notes Due 2008 (the "New Notes") issued by the Issuers, for each $1,000
principal amount of unregistered 10% Senior Notes Due 2008 (the "Old Notes")
issued by the Issuers of which an aggregate principal amount of $110,000,000 is
outstanding. The form and terms of the New Notes are identical to the form and
terms of the Old Notes except that the New Notes are being registered under the
Securities Act of 1933, as amended (the "Securities Act"), and will not bear any
legends restricting their transfer. The New Notes will evidence the same debt as
the Old Notes and will be issued pursuant to, and entitled to the benefits of,
the indenture governing the Old Notes. Interest on the New Notes shall accrue
from the date of issuance of the Old Notes. The Exchange Offer is being made in
order to satisfy certain contractual obligations of the Issuers. See "The
Exchange Offer" and "Description of New Notes." The New Notes and the Old Notes
are sometimes collectively referred to herein as the "Notes."
 
    Interest on the New Notes will be payable semi-annually on May 1 and
November 1 of each year, commencing November 1, 1998. The Company will not be
required to make any sinking fund payment with respect to the New Notes. The New
Notes will not be redeemable at the option of the Issuers prior to May 1, 2003,
except that until May 1, 2001, the Issuers may redeem, at their option, in the
aggregate up to 35% of the original principal amount of the Notes, on a pro rata
basis, at the redemption price set forth herein with the net proceeds of one or
more Public Equity Offerings (as defined) if at least $71.5 million aggregate
principal amount of the Notes remains outstanding after each such redemption. On
and after May 1, 2003, the Notes may be redeemed at the option of the Issuers,
in whole or in part, at the redemption prices set forth herein, plus accrued and
unpaid interest to the date of redemption. See "Description of New
Notes--Optional Redemption."
 
    The net proceeds to the Issuers from the sale of the Old Notes (the
"Original Offering") were placed in escrow to be used to (a) partially fund the
construction of two premium jackup offshore drilling rigs (the "Rigs"), (b) pay
interest on the Notes through the first two semi-annual interest payment dates
(see "Description of New Notes--Escrow of Proceeds") and (c) provide working
capital. One of the Rigs will be wholly owned and operated by Chiles Columbus
LLC and the other by Chiles Magellan LLC, each a Delaware limited liability
company and a wholly owned subsidiary of the Company (each, an "Owner" and,
collectively, the "Owners").
 
    In the event that a Construction Contract (as defined) with respect to a Rig
is terminated prior to delivery of such Rig, or in certain circumstances,
following an Event of Loss (as defined), after delivery of a Rig, each Holder
(as defined) shall have the right to require the Issuers to purchase the
Allocated Principal Amount (as defined) of such Holder's Notes for such Rig at a
purchase price equal to 101% of the principal amount thereof, plus accrued and
unpaid interest to the date of purchase. See "Description of New Notes--Right to
Require Repurchase Upon Contract Termination." Upon a Change of Control (as
defined), each Holder shall have the right to require the Issuers to purchase
such Holder's Notes, in whole or in part, at a purchase price equal to 101% of
the principal amount thereof, plus accrued and unpaid interest to the date of
purchase. See "Description of New Notes--Change of Control."
 
    The New Notes will be senior obligations of the Issuers, will rank PARI
PASSU with all existing and future senior indebtedness of the Issuers and will
be senior in right of payment to all future subordinated indebtedness. Except as
described herein with respect to the Collateral under the Escrow Security
Agreement (each as defined), the New Notes will be unsecured, and effectively
subordinated to the claims of secured creditors to the extent of the collateral
securing such claims. Concurrently with, and as a condition to, the closing of
the Original Offering, the Company entered into a $25.0 million bank credit
agreement (the "Bank Facility"), which is secured by substantially all the
assets of the Company and its subsidiaries, including the Rigs, other than the
Collateral under the Escrow Security Agreement. See "Description of New
Notes--Ranking" and "Description of Bank Facility." Payment of the principal of,
premium, if any, and interest on the New Notes will be guaranteed, jointly and
severally, on an unsecured basis by the Company's Restricted Subsidiaries (as
defined), which includes the Owners, both of which have also guaranteed, jointly
and severally, the Bank Facility on a secured basis. The guarantees of the
Company's Restricted Subsidiaries will be irrevocable and unconditional, but
limited in amount to the extent required by laws relating to fraudulent transfer
or similar laws. See "Risk Factors--Effective Subordination of the Notes;
Dependence on Subsidiaries" and "Description of New Notes--
Guarantees."                                            (CONTINUED ON NEXT PAGE)
 
    SEE "RISK FACTORS" BEGINNING ON PAGE 11 FOR A DISCUSSION OF CERTAIN
INFORMATION THAT SHOULD BE CONSIDERED IN CONNECTION WITH AN INVESTMENT IN THE
NEW NOTES.

(CONTINUED FROM FRONT COVER)
 
    The Company is a recently formed entity with no significant prior operating
history. Finance was formed to consummate the Original Offering as a co-issuer
of the Notes, and will conduct no other business. Certain institutional
investors that might otherwise be limited in their ability to invest in
securities issued by limited liability companies, by reason of the legal
investment laws of their states of incorporation or their charter documents, may
be able to invest in the Notes because Finance is a co-obligor. Certain of the
Company's subsidiaries (the "Guarantors") will guarantee, jointly and severally
on an unsecured basis, the New Notes (collectively, the "Subsidiary
Guarantees"). The Company and the Guarantors will accept for exchange any and
all Old Notes validly tendered and not withdrawn prior to 5:00 p.m., New York
City time, on         , 1998, unless extended (as so extended, the "Expiration
Date"). Tenders of Old Notes may be withdrawn at any time prior to the
Expiration Date. The Exchange Offer is subject to certain customary conditions.
See "The Exchange Offer."
 
    In order for a holder of Old Notes to participate in the Exchange Offer,
such holder must represent to the Issuers that, among other things, (i) the New
Notes acquired pursuant to the Exchange Offer are being obtained in the ordinary
course of business of the person receiving New Notes, whether or not such person
is the holder of the Old Notes, (ii) neither the holder nor any such other
person is engaging in or intends to engage in a distribution of such New Notes,
(iii) neither the holder nor any such other person has an arrangement or
understanding with any person to participate in the distribution of such New
Notes and (iv) neither the holder nor any such other person is an "affiliate,"
as defined under Rule 405 promulgated under the Securities Act, of either of the
Issuers. See "The Exchange Offer--Purpose and Effect."
 
    Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. The letter of transmittal
accompanying this Prospectus (the "Letter of Transmittal") states that by so
acknowledging and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.
This Prospectus, as it may be amended or supplemented from time to time, may be
used by a broker-dealer in connection with resales of New Notes received in
exchange for Old Notes where such Old Notes were acquired by such broker-dealer
as a result of market-making activities or other trading activities. The Issuers
have agreed that, for a period of 180 days after the Expiration Date (as defined
herein), they will make this Prospectus available to any broker-dealer for use
in connection with any such resale. See "Plan of Distribution."
 
    No public market has existed for the Old Notes before the Exchange Offer.
The Company and the Guarantors currently do not intend to list the New Notes on
any securities exchange or to seek approval for quotation through any automated
quotation system, and no active public market for the New Notes is currently
anticipated. The Issuers and the Guarantors will pay all the expenses incident
to the Exchange Offer.
 
    The Exchange Offer is not conditioned upon any minimum principal amount of
Old Notes being tendered for exchange pursuant to the Exchange Offer.

                                  THE COMPANY
 
    The Company was formed in 1997 for the purpose of constructing, owning and
operating a fleet of state-of-the-art premium jackup offshore drilling rigs. In
1997, the Company commenced construction of the first two such rigs at the
AMFELS, Inc. ("AMFELS") shipyard in Brownsville, Texas under fixed-price
contracts. The first rig, the CHILES COLUMBUS, is a LeTourneau Enhanced 116-C
design, and the second, the CHILES MAGELLAN, is a LeTourneau Super 116 design
(together, the "Rigs"). The Company expects that it will pay, net of capitalized
interest, $83.5 million and $87.8 million, respectively, in total construction
and outfitting costs for the Rigs. The Company and AMFELS have scheduled the
Rigs for delivery in April and September 1999, respectively.
 
    SEACOR SMIT Inc. ("SEACOR"), operator of the second largest fleet of
offshore service vessels in the world, has invested $35.0 million for
approximately 55.4% of the outstanding equity interests in the Company. SEACOR
is a Delaware corporation whose common stock is listed for trading on the New
York Stock Exchange under the symbol "CKH." The remaining equity interests in
the Company are held by private investors, including the original founders and
senior management.
 
    The Company's management team has extensive experience in the offshore
contract drilling industry. William E. Chiles, the President and CEO of the
Company, has over 25 years of experience in the industry. During his career, Mr.
Chiles founded or co-founded three offshore contract drilling companies and
supervised the construction of four jackup rigs at the Brownsville, Texas
shipyard facility where the Rigs are being constructed. The Company's operating
and engineering personnel have substantial experience operating, marketing,
building, refurbishing and upgrading premium jackup rigs, including the
LeTourneau 116-C design.
 
                                    THE RIGS
 
    Jackup rigs are the largest category of mobile offshore drilling units,
representing approximately 60% of such units. Oil and gas exploration companies
use jackup rigs extensively for offshore drilling in water depths from 20 feet
to 350 feet. Jackup rigs are mobile, self-elevating drilling platforms equipped
with legs that are lowered to the ocean floor until a foundation is established
to support the drilling platform. A jackup rig consists of the hull, jacking
system, drilling equipment, crew quarters, loading and unloading facilities,
storage areas, heliport and other related equipment. A jackup rig is towed to
the drillsite with its hull riding in the sea and its legs retracted. At the
drillsite, the legs are jacked down to the ocean floor until the hull has been
elevated a sufficient distance above the water to allow storm waves to pass
beneath. Jackup rigs vary a great deal in size and capability. Premium jackup
drilling rigs are distinguished by their technological features, which generally
allow for increased productivity, flexibility and safety of operation. Most
premium jackup rigs have a drillstring cantilevering feature that enables the
drilling of multiple exploratory or development wells from the same location
over an existing fixed production platform. The Company defines premium jackup
rigs as cantilevered jackup rigs capable of operating in water depths of 300
feet or greater, excluding (due to their substantially higher construction cost)
the class of jackup rigs built for service in "harsh environments," such as the
North Sea and Eastern Canada.
 
                                       1

    The Rigs will be state-of-the-art premium jackup drilling rigs capable of
operating at a water depth of 360 feet. Both Rigs incorporate the LeTourneau
Super 116's hull design and enhanced design features together with a
technologically advanced equipment package, which the Company believes provide
greater versatility and production efficiency compared to other rigs of similar
class. Each of the Rigs will feature 70-foot cantilevering capability, the
maximum reach currently available in the premium jackup rig market. The Rigs
will have capabilities that substantially exceed those of typical existing
premium jackup rigs, including increased engine horsepower, increased hydraulic
horsepower and enlarged mud handling and solids control systems. The Rigs will
also incorporate such features as digital drilling controls, dual pipe handling,
pipe handling robotics and drillpipe identification and tracking systems. The
Company expects that the Rigs will differentiate themselves in particular by
their increased productivity, mainly resulting from their superior engine and
hydraulic horsepower.
 
    The Company expects to operate the Rigs initially in the Gulf of Mexico, but
with certain modifications, the Rigs are capable of operating in essentially all
markets for jackup rigs, except for "harsh environment" drilling areas. Other
non-"harsh environment" markets include West Africa, Southeast Asia, Latin
America, the Middle East/Persian Gulf and the southern sector of the North Sea.
The Company believes that the superior operating performance of the Rigs will
enable it to enter into attractive drilling contracts with high quality
customers at the appropriate time.
 
                                MARKET OVERVIEW
 
    The world's jackup rig fleet currently consists of 380 rigs, which vary
significantly in terms of technological advancement, water depth capability and
age. A total of 117 are premium jackup rigs and as of March 1998, 29 such rigs
were employed in the Gulf of Mexico, the largest single market for jackup rigs.
The current average age of the world's jackup rig fleet is 17.5 years with
premium jackup rigs having an average age of 16.4 years, which compares to an
expected original useful life for such units of approximately 25 years. In
addition to the Company's Rigs, seven other jackup rig newbuildings are on order
with shipyards around the world (collectively representing 2.4% of the existing
fleet), of which six are jackup rigs designed for work in "harsh environment"
areas.
 
    Based on published industry data, the Company estimates that as of March 31,
1998, the average dayrate for premium jackup rigs worldwide was $73,000 and that
it averaged $62,000 in 1997 and $39,000 in 1996. (1997 and 1996 dayrate data
include a small number of "harsh environment" jackup rigs, which increases
slightly the average historical dayrate information for premium jackup rigs.)
Based on published industry data, the Company estimates that premium jackup rig
utilization levels have averaged 93% over the last ten years and that as of
March 31, 1998, average utilization exceeded 96%. Major factors underlying these
improvements include an increase in demand due to greater offshore exploration
and development expenditures by the world's oil and gas companies, and a
reduction in rig supply, due to the advancing age of the existing fleet and the
small number of newbuildings. Growth in offshore expenditures by oil and gas
companies has been due in part to substantial technological advances in
exploration and production (including 3-D seismic, horizontal drilling and
subsea completion procedures), which have reduced the overall cost of finding
and producing oil and gas. In addition, the offshore drilling industry has
experienced a worldwide consolidation during the last ten years which has
substantially reduced the number of drilling contractors.
 
                               BUSINESS STRATEGY
 
    The Company intends to become a leading provider of state-of-the-art premium
jackup rigs and to maximize dayrates and rig utilization by offering its
customers the most productive premium jackup rigs available. The Company will
focus on establishing a reputation for customer service, higher productivity and
safety of operation in the offshore contract drilling market. The key elements
of the Company's strategy are as follows:
 
    - FOCUS ON PREMIUM JACKUP RIG MARKET. The Company will focus on premium
      jackup rigs, which the Company believes enjoy strong and growing worldwide
      demand, have the versatility to work in a
 
                                       2
<PAGE>
      variety of different markets, represent a relatively low investment
      compared to new semisubmersibles, drillships and "harsh environment"
      jackup rigs, possess a favorable relationship between potential revenues
      and operating costs, and are familiar to the management of the Company
      through prior operations and newbuildings.
 
    - OWN AND OPERATE HIGH QUALITY ASSETS. The Rigs will represent a new
      generation of premium jackup rigs with significantly enhanced capabilities
      incorporating the latest technologies. Such capabilities will assist the
      Company in offering its customers equipment with superior productivity and
      safety features.
 
    - BUILD TO MEET STRONG DEMAND GROWTH. The Company intends to be among the
      first offshore drilling contractors to provide new generation premium
      jackup rigs to the industry. The Company believes that this is the early
      stage of a period of strong growth in the demand for, and utilization of,
      premium jackup rigs. The Company believes that it has been able to secure
      favorable contract terms by placing orders during this early stage, at a
      time when relatively few new premium jackup rigs are being built.
 
    - EXPAND RIG FLEET. The Company expects to expand its rig fleet prudently
      over time. The Company may achieve this growth through the exercise of
      three sequential options (the "Construction Options") that the Company
      holds to construct additional LeTourneau Super 116 design premium jackup
      rigs at a total delivered cost of approximately $100.0 million per rig.
 
    - FOCUS ON THE GULF OF MEXICO. The Company will focus its operations
      initially on the Gulf of Mexico market, which is the largest single market
      for jackup rigs in the world. Furthermore, the presence of an established
      pipeline and production infrastructure makes the Gulf of Mexico an
      economically attractive market for continued exploration and production
      activity.
 
    - UTILIZE SEACOR EXPERTISE. SEACOR will directly advise the Company
      concerning strategic, financial and marketing matters through
      representation on the Company's Management Committee (I.E., its board of
      directors). Additionally, pursuant to the Services Agreement (as defined),
      SEACOR has made available its Vice President, Finance to serve as the
      Company's Senior Vice President and Chief Financial Officer. The Company
      believes that SEACOR's marketing expertise and its extensive oil and gas
      company client base will greatly assist the Company in the marketing of
      the Rigs.
 
    - EMPLOY, RETAIN AND MOTIVATE EXPERIENCED AND INCENTIVIZED MANAGEMENT. The
      Company will seek to employ, retain and motivate experienced senior
      management and key employees through the implementation of an equity
      participation and performance incentive program.
 
                                 THE FINANCING
 
    The Company intends to finance construction of the Rigs and the start-up
phase of its operations through aggregate capital contributions of $63.9 million
(of which $55.4 million has been received in cash) from SEACOR, the original
founders and other equity investors (the "Equity Financing"), $110.0 million in
gross proceeds from the Original Offering and borrowings under its $25.0 million
Bank Facility. The Company consummated the final phase of the Equity Financing
on December 16, 1997 and the Original Offering on April 29, 1998, the date of
original issuance of the Notes (the "Issue Date"). As of March 31, 1998, a total
of approximately $36.6 million of the cash proceeds of the Equity Financing had
been spent on construction of the Rigs, offering costs associated with the
Equity Financing and supporting activities and at such date the Company had
approximately $18.8 million cash on hand. The Company anticipates that less than
half of the Bank Facility will be drawn at the time the second Rig is scheduled
to be delivered, and therefore the undrawn portion thereof would be available
for debt service and other general corporate purposes.

                           THE CONSTRUCTION PROJECTS
 
    The scheduled delivery dates (each, a "Scheduled Delivery Date") of the Rigs
will be April 30, 1999 for the CHILES COLUMBUS and September 10, 1999 for the
CHILES MAGELLAN. The Company expects the total construction cost of the CHILES
COLUMBUS to be approximately $83.5 million and the total construction cost of
the CHILES MAGELLAN to be approximately $87.8 million, in each case net of
capitalized interest. The major components of the construction costs are the
fixed contract prices payable to AMFELS pursuant to the respective Platform
Construction Agreement (the "Construction Contract") for each Rig, the cost of
owner furnished equipment ("OFE"), which includes the major components of the
drilling and power system (including engines, generators, draw works and top
drives), and the Company's internal expenditures during the construction period.
The Company currently has contracted for over 95% of the total cost of OFE on a
fixed-price basis. The total amount of these expenditures is summarized in the
following table:

    The AMFELS shipyard, originally built and operated by Marathon LeTourneau,
Inc., has a long-term commitment to the offshore drilling industry and many of
the key personnel who designed and built LeTourneau jackup rigs in the past are
currently working there. The shipyard's newbuilding construction

experience includes 24 jackup rigs and two semisubmersibles. AMFELS is 100%
owned by Keppel FELS, Ltd., an established international shipyard and
engineering group based in Singapore. To mitigate the risk of a delay in
construction, the Company has procured standard "delay-in-delivery" insurance
that provides for coverage of $30,000 per day per Rig up to a maximum of 360
days for certain delays in excess of 30 days up to a total combined limit of
$21.6 million for both Rigs.
 
                               THE EXCHANGE OFFER
 
    The Exchange Offer applies to $110.0 million aggregate principal amount of
the Old Notes. The form and terms of the New Notes are the same as the form and
terms of the Old Notes except that the New Notes are being registered under the
Securities Act and, therefore, will not bear legends restricting their transfer.
The New Notes will evidence the same debt as the Old Notes and will be entitled
to the benefits of the Indenture pursuant to which the Old Notes were issued.
Interest on the New Notes shall accrue from the date of issuance of the Old

                                  RISK FACTORS
 
    HOLDERS OF OLD NOTES SHOULD CONSIDER CAREFULLY THE RISK FACTORS SET FORTH
BELOW, AS WELL AS THE OTHER INFORMATION SET FORTH HEREIN, BEFORE DECIDING TO
TENDER OLD NOTES IN THE EXCHANGE OFFER. THE RISK FACTORS SET FORTH BELOW ARE
GENERALLY APPLICABLE TO THE OLD NOTES AS WELL AS THE NEW NOTES.
 
    THIS PROSPECTUS CONTAINS STATEMENTS THAT CONSTITUTE FORWARD-LOOKING
STATEMENTS. THOSE STATEMENTS ARE SUBJECT TO A NUMBER OF RISKS AND UNCERTAINTIES,
INCLUDING, WITHOUT LIMITATION, THE FACTORS SET FORTH BELOW, MANY OF WHICH ARE
BEYOND THE COMPANY'S CONTROL. SEE "DISCLOSURE REGARDING FORWARD-LOOKING
STATEMENTS."
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
    Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject to the restrictions
on transfer of such Old Notes as set forth in the legend thereon. In general,
Old Notes may not be offered or sold unless registered under the Securities Act,
except pursuant to an exemption from, or in a transaction not subject to, the
registration requirements of the Securities Act and applicable state securities
laws. The Company does not currently intend to register the Old Notes under the
Securities Act. Based on interpretations by the staff of the Commission, the
Company believes that New Notes issued pursuant to the Exchange Offer in
exchange for Old Notes may be offered for resale, resold or otherwise
transferred by Holders thereof (other than any such Holder which is an
"affiliate" of either of the Issuers or either of the Guarantors within the
meaning of Rule 405 under the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that such Old Notes were acquired in the ordinary course of such Holders'
business and such Holders have no arrangement with any person to participate in
the distribution of such New Notes. Each broker-dealer that receives New Notes
for its own account in exchange for Old Notes, where such Old Notes were
acquired by such broker-dealer as a result of market-making activities or other
trading activities, must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. See "Plan of Distribution." To the
extent that Old Notes are tendered and accepted in the Exchange Offer, the
trading market for untendered and tendered but unaccepted Old Notes will be
adversely affected.
 
DEPENDENCE ON OIL AND NATURAL GAS INDUSTRY; INDUSTRY CONDITIONS; MARKET
  VOLATILITY
 
    The Company's business and operations are materially dependent upon the
condition of the oil and natural gas industry and, specifically, the exploration
and production expenditures of oil and gas companies. Due to the Company's
initial focus on the Gulf of Mexico, the Company's business and operations will
be particularly dependent upon the condition of the oil and natural gas industry
in the Gulf of Mexico and on the exploration and production expenditures of oil
and gas companies there. Historically, the offshore contract drilling industry
has been highly competitive and cyclical, with periods of high demand, short rig
supply and high dayrates followed by periods of low demand, excess rig supply
and low dayrates. The offshore contract drilling business is influenced by a
number of factors, including the current and anticipated prices of oil and
natural gas, the expenditures by oil and gas companies for exploration and
production and the availability of drilling rigs. Throughout the 1980s and early
1990s, depressed oil and natural gas prices and an oversupply of rigs adversely
affected the offshore drilling market, particularly in the U.S. Gulf of Mexico,
where the prolonged weakness and uncertainty in the demand for and price of
natural gas resulted in a significant decline in exploration and production
activities and, accordingly, a decline in dayrates. The Company cannot predict
the future level of demand for its services or future conditions of the oil and
natural gas industry. Any decrease in exploratory and production expenditures by
oil and gas companies could have a material adverse effect on the Company's
business and results of operations.

LIMITED LIABILITY OF AMFELS; CONSEQUENCES OF DELAY OR NONCOMPLETION OF RIGS;
  NON-PERFORMANCE BY AMFELS
 
    As with any major construction undertaking, completion of the Rigs could be
delayed or prevented, or cost overruns could be incurred, as a result of
numerous factors including shortages of materials, failure or delay of
LeTourneau, Inc. ("LeTourneau") or other third party providers, labor disputes,
weather interferences, difficulties in obtaining necessary permits or in meeting
permit conditions or unforeseen engineering problems. No representation or
assurance can be made that the Rigs will be successfully constructed or, if
constructed, completed on time. If the Rigs are not completed on time or are not
capable of operating according to their respective design specifications, in
certain circumstances, the applicable Scheduled Delivery Date may be extended
and, in certain other circumstances, termination of the applicable Construction
Contract may be the Company's sole remedy for such failure. The Company will
maintain insurance to protect against certain delays in delivery caused by
specified events, including physical loss or damage to the Rigs in the shipyard
during construction as a result of named perils, including labor disturbances,
delays in delivery of materials required for construction as a result of such
events and delays resulting from restricted access to the shipyard as a result
of such events. However, the coverage provided under such insurance is subject
to significant exceptions and would not provide protection against certain
delays in delivery.
 
    If completion of one or both of the Rigs is delayed or prevented due to (i)
any act or omission of the Company, including failure to timely deliver to
AMFELS any equipment to be furnished by the Company, or (ii) delays caused by
the American Bureau of Shipping or any governmental agency, changes, any of a
wide variety of events of FORCE MAJEURE under the applicable Construction
Contract, or inability or failure of LeTourneau to perform its obligations under
the applicable LeTourneau Agreement (as defined), or if all subjects and
conditions under the applicable LeTourneau Agreements are not fully and timely
met by LeTourneau, the applicable Scheduled Delivery Date(s) will be extended by
the applicable period. In the event of the occurrence of any of the foregoing,
or if the Rigs cannot achieve operation in accordance with their respective
design specifications, AMFELS would not be obligated to pay liquidated damages.
AMFELS would be excused from performance and would not be in default under the
applicable Construction Contract. In addition, the date for achievement of
substantial completion and the Scheduled Delivery Date, as defined in the
respective Construction Contract, would be subject to adjustment as a result
thereof. See "Business--The Construction Contracts--Scheduled Delivery Dates."
If AMFELS does not achieve substantial completion by the Scheduled Delivery
Date, or if a Rig does not perform in accordance with its design specifications,
or if after achieving substantial completion a failure of a Rig to perform in
accordance with its design specifications causes a suspension or curtailment of
operations of such Rig after the applicable Scheduled Delivery Date, the
Company's ability to make payments of principal and interest on the Notes may be
materially adversely affected.
 
    Under the Construction Contracts, the Company is responsible for a number of
matters in connection with the construction and completion of the Rigs. While
the Company believes that it has made adequate arrangements to assure timely
performance of such responsibilities, the Company is relying on the other
parties to certain contracts to enable it to perform its responsibilities under
the Construction Contracts and there can be no assurance that such other parties
will meet their obligations under such contracts.
 
    If completion of one or both of the Rigs is delayed or prevented due to the
failure by AMFELS to perform, or the breach by AMFELS of, any of its covenants,
agreements or undertakings under the applicable Construction Contract beyond the
applicable cure period, the Company's sole remedy may be to terminate the
related Construction Contract. Under the Construction Contracts, the Company may
terminate the Construction Contracts upon the occurrence of an event of default
by AMFELS, including such a failure by AMFELS to perform, or the breach by
AMFELS of, any of its covenants, agreements or undertakings under the applicable
Construction Contract, which AMFELS has failed to commence diligently to cure
within thirty (30) days or which remains uncured for ninety (90) days, in each
case, after notice thereof by the Company. In addition, each of the Construction
Contracts provides for its automatic
 
                                       12
<PAGE>
termination if, prior to delivery, an actual or constructive total loss occurs
with respect to a Rig. See "Business--The Construction Contracts." In the event
of any such termination, the Company's ability to make payments of principal and
interest on the Notes may be materially adversely affected.
 
COMPANY DEPENDENCE ON RIGS' PERFORMANCE FOR REVENUES; CONSTRUCTION AND MARKETING
  RISKS
 
    Until the first Rig to be delivered from the shipyard commences operation,
debt service on the Notes will be payable solely from the Escrowed Property (as
defined) in the Interest Escrow Account (as defined). Thus, in the event of a
prolonged delay beyond the Rigs' respective Scheduled Delivery Dates, no
assurance can be given that sufficient sources of funds will be available to
make payments of principal and interest on the Notes. See "--Limited Liability
of AMFELS; Consequences of Delay or Noncompletion of Rigs; Non-Performance by
AMFELS." Thereafter, payments pursuant to drilling contracts are expected to
provide substantially all of the Company's revenues. Any material failure by the
Rigs to maintain anticipated utilization levels and to receive anticipated
average dayrates would therefore have a material adverse effect on the Company's
revenues and the Company's ability to make payments of principal of and interest
on the Notes. Moreover, the recent improvement in the current results of
operations and prospects for the offshore contract drilling industry as a whole
may lead to increased rig construction and enhancement programs by the Company's
competitors. A significant increase in the supply of premium jackup rigs could
have an adverse effect on the average utilization and average dayrates for the
Rigs. In such case, the Company's results of operations would be adversely
affected. Profitability of the Company in the future will depend upon the
utilization and dayrates for the Rigs and the Company's ability to control
operating costs. There is no assurance that current utilization and dayrates
will not decline, or that current average operating costs will not escalate, or
that the Company will be able to meet its debt service obligations in the
future.
 
    The Company at present is constructing only the two Rigs. If either of the
Rigs suffers an actual or total casualty loss or significant damage or suffers
mechanical or other difficulties, or if for any other reason such Rig is not
capable of normal operations for any extended period, the Company's results of
operations would be, and its ability to meet its debt service obligations could
be, materially and adversely affected.
 
    The Rigs currently are under construction and the Company will not receive
any material revenues unless and until the Rigs achieve commercial operation.
The Company has not executed a drilling contract for either of the Rigs. In
addition, there is no assurance that any drilling contract that may be signed
will be a term contract, I.E., any such contract or contracts may be
"well-to-well," and the Company may market the Rigs on that basis at any time
and from time to time. Thus, there may be periods in the future when one or both
of the Rigs are not under contract and thus, not producing revenues. Moreover,
during any such period, the Company will continue incurring the expense of
maintaining the affected Rig in the "stacked" mode pending execution of a
contract. Finally, if a Rig is not working because of adverse demand conditions
in the local market, the Company may incur unreimbursed expenses to mobilize the
Rig from that market to another where demand conditions are more favorable.
 
EARLY STAGE OF DEVELOPMENT; OPERATING LOSSES
 
    The Company is at an early stage of development. The Company has no
significant operating history for periods prior to the Original Offering.
Finance and the Owners have no operating history or financial statements for any
periods prior to the Original Offering. Consequently, the Company has no
substantial commercial operating history for investors to evaluate in making an
investment decision.
 
    The Company is subject to all of the risks inherent in the establishment of
a new business enterprise. Since its inception, the Company has recognized no
operating revenue, has incurred losses and has had a negative cash flow from
operations, exclusive of accounts payable. The Company reported a loss from
operations of approximately $0.08 million and $0.38 million for the three months
ended March 31, 1998
 
                                       13
<PAGE>
and for the period from inception to December 31, 1997, respectively. There can
be no assurance that the Company will generate significant revenues or achieve
or sustain profitability in the future. In addition, there can be no assurance
that the Company will successfully complete the transition from a development
stage company to successful operations. As a result of the aforementioned
factors and the related uncertainties, there can be no assurance of the
Company's future success.
 
    The development of the Company's business, including construction of the
Rigs, will require significant capital expenditures, virtually all of which will
be incurred before the realization of revenue. The Company expects that the
expenditures required to complete construction of the Rigs, together with the
associated early operating expenses, will result in negative cash flow until at
least one of the Rigs has been deployed. There can be no assurance that the
Company's estimates of its future losses or of its expected negative cash flow
will be accurate or that the Company's need for additional capital to fund
operating losses or capital needs will not continue substantially longer than
expected.
 
    The Company is currently pursuing a business strategy that includes
obtaining drilling contracts with oil and gas operators, employment of rig
personnel, obtaining additional financing to complete the construction of the
Rigs and fund the purchase of drilling equipment, and overseeing the
construction of the Rigs and installation of the drilling equipment. There are
no assurances that this business strategy will be achieved. While pursuing this
business strategy, the Company will experience cash flow deficits until the
Rigs' construction is completed and the Rigs are placed in operation. As a
result of the aforementioned factors and related uncertainties, the Company's
auditors have raised a substantial doubt as to the Company's ability, in their
audit report to the Members of Chiles Offshore LLC dated February 11, 1998, to
continue as a going concern. The Company's financial statements included
elsewhere herein do not include any adjustments relating to the recoverability
and classification of asset carrying amounts or the amount and classification of
liabilities that might result should the Company be unable to continue as a
going concern.
 
FINANCIAL FORECAST
 
    The financial forecast set forth under "Certain Financial Forecast
Information" (the "Forecast") is based upon certain assumptions and estimates,
some of which may not materialize, and unanticipated events may occur that could
materially adversely affect the actual results achieved by the Company during
the forecast period. Consequently, the Company's actual results of operations
during the forecast period will vary from the Forecast and such variations may
be material. In addition, prospective investors should understand that the
degree of uncertainty increases with each successive period presented. The
Company's independent public accountants have not examined, compiled, reviewed,
or applied agreed-upon procedures to the Forecast, and consequently, assume no
responsibility for the Forecast. The Forecast has not been prepared in
compliance with the published guidelines of the American Institute of Certified
Public Accountants. The Forecast has been prepared by the Company as of March
31, 1998 and presents management's best estimate as of such date of the
Company's revenue, operating expenses and net income for each of the years in
the three-year period ending December 31, 2001. The Company does not intend to
update or otherwise revise the Forecast to reflect events or circumstances
existing or arising after March 31, 1998 or to reflect the occurrence of
unanticipated events. Prospective investors should make their own independent
assessment of the ability of the Company to make principal and interest payments
on the Notes. The Forecast should not be relied upon for any purpose following
the consummation of the Original Offering. No assurance can be given that the
Company's cash flow from operations will be sufficient to pay, when due, the
principal of and interest on the Notes. See "Disclosure Regarding
Forward-Looking Statements."
 
SUBSTANTIAL LEVERAGE; ABILITY TO SERVICE DEBT
 
    The Company is highly leveraged following consummation of the Original
Offering. Upon consummation of the Original Offering, the Company's outstanding
total long-term debt was comprised of
 
                                       14
<PAGE>
$110.0 million of Notes. In addition, the Company has $25.0 million of unused
senior secured borrowing capacity under the Bank Facility. The degree to which
the Company is leveraged could have important consequences to holders of the
Notes, including (i) the Company's ability to obtain additional financing in the
future for working capital, capital expenditures, acquisitions, general
corporate purposes or other purposes may be impaired; (ii) a substantial portion
of the Company's cash flow from operations will be dedicated to the payment of
principal and interest on its indebtedness, thereby reducing the funds available
to the Company for its operations and expansion plans; and (iii) the Company may
be more vulnerable to a downturn in general economic conditions or its business.
The Company's borrowings under the Bank Facility are at floating rates of
interest, which could result in a higher interest expense in the event of an
increase in interest rates.
 
    The Company's ability to make scheduled payments or to refinance its
obligations with respect to its indebtedness depends on its financial and
operating performance, which, in turn, is subject to prevailing economic
conditions and to financial, business and other factors beyond its control and
to the ability of Chiles to access payments and advances from its subsidiaries
in amounts and at times sufficient to fund its debt obligations. Further, there
can be no assurance that the Company's operating results or Chiles's access to
payments and advances from its subsidiaries will be sufficient for payment of
the Company's indebtedness, including the Notes. See "--Effective Subordination
of the Notes; Dependence on Subsidiaries."
 
EFFECTIVE SUBORDINATION OF THE NOTES; DEPENDENCE ON SUBSIDIARIES
 
    The Notes will be effectively subordinated to all current and future secured
indebtedness of the Company and of any future subsidiaries of Chiles, including
indebtedness under the Bank Facility, to the extent of any mortgaged or pledged
assets. The Company's obligations under the Bank Facility will be secured by
first priority mortgages on the Rigs and by a pledge of substantially all of the
Owners' other assets. Therefore, in the event of a bankruptcy, liquidation or
reorganization of the Company, the assets of the Company would be available to
pay obligations on the Notes only after all such indebtedness has been paid in
full, and in such event there may not be sufficient assets remaining to pay
amounts due on any or all of the Notes then outstanding. The indebtedness under
the Bank Facility will become due prior to the time the principal obligations
under the Notes become due. Upon consummation of the Original Offering, there
was (and upon consummation of the Exchange Offer, there will be) $25.0 million
of unused senior secured borrowing capacity under the Bank Facility.
 
    In addition, the operations of the Company will be conducted primarily
through the Owners and any future Chiles subsidiaries. Therefore, the Company's
ability to make required principal and interest payments with respect to the
Notes will depend on the earnings of such subsidiaries and on its ability to
receive funds from such subsidiaries through dividends or other payments.
 
RESTRICTIVE COVENANTS
 
    Among other things, the covenants contained in the Indenture restrict,
condition or prohibit the Company from incurring additional indebtedness,
creating certain liens on its assets, making certain asset dispositions,
entering into transactions with affiliates, merging or consolidating with any
other person or selling, assigning, transferring, leasing, conveying or
otherwise disposing of substantially all the assets of the Company. In addition,
the Bank Facility contains certain financial and operating covenants and
prohibitions. There can be no assurance that the Company's leverage and such
restrictions will not materially and adversely affect the Company's ability to
finance its future operations or capital needs or to engage in other business
activities. Moreover, a failure to comply with the obligations contained in the
Indenture governing the Notes or any other agreements with respect to additional
financing (including the Bank Facility or any replacement facility) could result
in an event of default under such agreements, which could permit acceleration of
the related debt and acceleration of debt under future debt agreements that
 
                                       15
<PAGE>
may contain cross-acceleration or cross-default provisions. See "Description of
Bank Facility" and "Description of New Notes."
 
DEPENDENCE ON KEY PERSONNEL
 
    While the Company's senior management has worked together extensively in the
past, the complete management team has not yet been fully assembled. The
Company's success depends to a large extent upon the continued services of its
senior management including, in particular, William E. Chiles, the President and
Chief Executive Officer of the Company, and its ability to attract and retain
key operating personnel. The loss of the services of any such employee could
have a material adverse effect on the Company. The Company does not maintain
"key man" insurance with respect to any such individuals. While the success of
the Company depends in large part upon such personnel, the Company believes that
there are other qualified managers in the offshore drilling industry whom the
Company might retain to fill such positions, if needed. However, there can be no
assurance that the Company would be able to engage such qualified managers and,
if so, on what terms. See "Management."
 
DEPENDENCE ON SKILLED LABOR
 
    The Company's financial performance is affected by the availability of
qualified personnel and the cost of labor. In recent years, unemployment rates
in the offshore contract drilling industry have reached unusually low levels
leading to lower availability of skilled labor and increased labor costs. While
the Company does not believe that contraction of the labor market will have a
material adverse effect on its financial performance, there can be no assurance
that sufficient labor will be available in the future or that the cost of labor
will not rise, either of which could have an adverse effect on the Company.
 
COMPETITION
 
    The contract drilling industry is highly competitive. Customers sometimes
award contracts on a competitive bid basis, and although a customer selecting a
rig may consider, among other things, a contractor's safety record, crew quality
and quality of service and equipment, price is the major factor in determining
the selection of a drilling contractor. The Company believes that competition
for drilling contracts will continue to be intense for the foreseeable future
because of the ability of contractors to move rigs from areas of low utilization
and dayrates to areas of greater activity and relatively higher dayrates. Such
movement or a decrease in drilling activity in any major market could depress
dayrates and could adversely affect utilization of the Company's Rigs. Most of
the Company's competitors are much larger and more established companies with
greater financial resources than the Company. See "Business-- Offshore Contract
Drilling Services."
 
    In addition, the current favorable conditions in the premium jackup rig
market may lead to additional newbuildings of rigs of this class. A significant
increase in the supply of state-of-the-art, technologically advanced premium
jackup rigs capable of competing with the Rigs may have an adverse effect on the
average operating dayrates for the Rigs, and on their average utilization
levels. In such case, the Company's results of operations would be adversely
affected.
 
RISKS IN INTERNATIONAL OPERATIONS
 
    All or a portion of the revenues from operation of the Rigs may be derived
from foreign operations and be subject, in varying degrees, to risks inherent in
doing business abroad. The Company's non-U.S. operations will be subject to
certain political, economic and other uncertainties not encountered in U.S.
operations, including risks of war and civil disturbances (or other risks that
may limit or disrupt markets), expropriation and the general hazards associated
with the assertion of national sovereignty over certain areas in which
operations are conducted. The Company's operations outside the United States may
face the additional risk of fluctuating currency values, hard currency
shortages, controls of currency exchange
 
                                       16
<PAGE>
and repatriation of income or capital. No prediction can be made as to what
governmental regulations may be enacted in the future that could adversely
affect the international drilling industry.
 
OPERATIONAL RISKS; INDEMNIFICATION AND INSURANCE
 
    The Company's operations will be subject to the many hazards inherent in the
offshore drilling business, including blowouts, craterings, fires, collisions
and groundings of drilling equipment, which could cause substantial damage to
the environment, and damage or loss from adverse weather and sea conditions.
These hazards could also cause personal injury and loss of life, suspend
drilling operations or seriously damage or destroy the property and equipment
involved and, in addition to environmental damage, could cause substantial
damage to producing formations and surrounding areas. The Company's offshore
drilling equipment will also be subject to hazards inherent in marine
operations, such as capsizing, grounding, collision, damage from weather or sea
conditions or unsound location. In addition, the Company may be subject to
liability for oil spills, reservoir damage and other accidents that could cause
substantial damages.
 
    The Company generally expects to be able to obtain contractual
indemnification pursuant to which the Company's customers would agree to protect
and indemnify the Company to some degree from liability for reservoir, pollution
and environmental damages, but there can be no assurance that the Company can
obtain such indemnities in all of its contracts, that the level of
indemnification that can be obtained will be meaningful, that such
indemnification agreements will be enforceable or that the customer will be
financially able to comply with its indemnity obligations. In addition, the
Company expects to maintain insurance coverage against loss of hire, property
damage, war risk (in the case of certain operations outside the U.S.), general
liability and environmental liabilities, including pollution caused by sudden
and accidental oil spills, 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 loss or liability in many
circumstances. Moreover, any such insurance is expected to be subject to
substantial deductibles and to provide for premium adjustments based on claims.
 
ENVIRONMENTAL AND OTHER REGULATIONS
 
    The Rigs and the operation of the Rigs must comply with extensive
environmental protection laws and regulations. Compliance with these laws and
regulations may entail significant expenses, including expenses for rig
modifications and changes in operating procedures. These laws and regulations
could have a material adverse effect on the business and the operations of the
Owners and the Company. Additional laws and regulations may be adopted in the
future which would have a material adverse effect on the business and the
operations of the Company. See "Business--Governmental Regulation."
 
POSSIBLE INABILITY TO REPURCHASE NOTES UPON CERTAIN EVENTS
 
    Upon the occurrence of a Change of Control, Contract Termination or, under
certain circumstances, an Event of Loss (each as defined), each holder of the
Notes will have the right to require the Company to repurchase any or all of the
Notes owned by such holder at a price equal to 101% of the principal amount
thereof, together with accrued and unpaid interest. However, the Company expects
that its ability to repurchase the Notes upon the occurrence of any such event
will be limited by the Bank Facility and by the terms of any other then existing
contractual obligations of the Company. In addition, the Company may not have
adequate financial resources to effect such a repurchase, and there can be no
assurance that the Company would be able to obtain such resources through a
refinancing of the Notes to be repurchased or otherwise. If the Company fails to
repurchase all of the Notes tendered for purchase upon the occurrence of any
such event, such failure will constitute an Event of Default (as defined) under
the Indenture. See "Description of New Notes--Change of Control," "--Right to
Require Repurchase Upon Contract Termination" and "--Certain
Covenants--Application of Event of Loss Proceeds."
 
                                       17
<PAGE>
    With respect to the sale of assets referred to in the definition of "Change
of Control," the phrase "all or substantially all" as used in such definition
varies according to the facts and circumstances of the subject transaction, has
no clearly established meaning under the relevant law and is subject to judicial
interpretation. Accordingly, in certain circumstances there may be a degree of
uncertainty in ascertaining whether a particular transaction would involve a
disposition of "all or substantially all" of the assets of a person and
therefore it may be unclear whether a Change of Control has occurred and whether
the Notes are subject to an offer to purchase.
 
    Except as described under "Description of New Notes--Change of Control," the
Indenture does not contain provisions that permit the holders of the Notes to
require the Company to repurchase or redeem the Notes in the event of a
takeover, recapitalization or similar transaction.
 
FRAUDULENT CONVEYANCE CONSIDERATIONS RELATING TO SUBSIDIARY GUARANTEES
 
    The obligations of Chiles and Finance under the Notes will be guaranteed
(the "Subsidiary Guarantees") on an unsecured basis by the Owners. Various
fraudulent conveyance laws have been enacted for the protection of creditors and
may be utilized by a court of competent jurisdiction to subordinate or avoid the
Subsidiary Guarantees issued by the Owners. It is also possible that under
certain circumstances a court could hold that the direct obligations of the
Owners could be superior to the obligations under the Subsidiary Guarantees.
 
    To the extent that a court were to find that (x) a Subsidiary Guarantee was
incurred by an Owner with the intent to hinder, delay or defraud any present or
future creditor or that such Owner contemplated insolvency with a design to
favor one or more creditors to the exclusion in whole or in part of others or
(y) an Owner did not receive fair consideration or reasonably equivalent value
for issuing its Subsidiary Guarantee and at the time it issued such Subsidiary
Guarantee, such Owner (i) was insolvent by reason of the issuance of the
Subsidiary Guarantee, (ii) was engaged or about to engage in a business or
transaction for which the remaining assets of such Owner constituted
unreasonably small capital or (iii) intended to incur, or believed that it would
incur, debts beyond its ability to pay such debts as they matured, the court
could avoid or subordinate the Subsidiary Guarantee in favor of the Owner's
other creditors. Among other things, a legal challenge of the Subsidiary
Guarantee issued by an Owner on fraudulent conveyance grounds may focus on the
benefits, if any, realized by the Owner as a result of the issuance by Chiles
and Finance of the Notes. To the extent a Subsidiary Guarantee is avoided as a
fraudulent conveyance or held unenforceable for any other reason, the holders of
the Notes would cease to have any claim in respect of such Owner and would be
creditors solely of Chiles and Finance and the other Owner, assuming its
Subsidiary Guarantee was not also avoided or held unenforceable.
 
    On the basis of financial information and other information currently
available to it, the Company believes that the Old Notes and the Subsidiary
Guarantees issued concurrently with the issuance of the Old Notes were incurred
for proper purposes and in good faith and that, after giving effect to
indebtedness incurred in connection with the issuance of the Old Notes and the
issuance of the Subsidiary Guarantees, the Company (including each Owner) was
and is solvent and will continue to be solvent, will have sufficient capital for
carrying on their respective business and will be able to pay their debts as
such debts become absolute and mature. There can be no assurance, however, that
a court passing on such questions would reach the same conclusions.
 
ABSENCE OF PUBLIC MARKET
 
    The New Notes will constitute a new issue of securities for which there is
no established trading market. The Company does not intend to list the New Notes
on any national securities exchange or to seek the admission of the New Notes
for quotation through the National Association of Securities Dealers Automated
Quotation System. Although the Initial Purchasers have advised the Company that
they currently intend to make a market in the New Notes, they are not obligated
to do so and may discontinue
 
                                       18
<PAGE>
such market making activity at any time without notice. In addition, such market
making activity will be subject to the limits imposed by the Securities Act and
the Exchange Act, and may be limited during the Exchange Offer and the pendency
of any shelf registration statement. Although the Old Notes have been designated
for trading in the PORTAL market, there can be no assurance as to the
development or liquidity of any market for the New Notes, the ability of the
Holders of the New Notes to sell their New Notes or the price at which the
Holders would be able to sell their New Notes. Future trading prices of the New
Notes will depend on many factors, including, among other things, prevailing
interest rates, the Company's operating results and the market for similar
securities.
 
                                       19
<PAGE>
                                USE OF PROCEEDS
 
    There will be no proceeds to the Company from the exchange of Old Notes
pursuant to the Exchange Offer.
 
    The net proceeds from the sale of the Old Notes in the Original Offering
were approximately $106.3 million, which the Company expects to use to (a)
partially fund the construction of the Rigs, (b) pay interest on the Notes
through the first two semi-annual interest payment dates and (c) provide working
capital. Pursuant to the Escrow Agreement, the Company deposited with the Escrow
Agent an amount in cash equal to the net proceeds of the Original Offering,
together with approximately $0.2 million for additional Notes issuance costs, as
follows: (i) into the Interest Escrow Account, approximately $11.1 million,
representing the amount sufficient to provide for payment in full of the first
two scheduled semi-annual interest payments on the Notes and (ii) into the
Construction Escrow Account (as defined), the balance of approximately $95.4
million. See "Description of New Notes--Escrow of Proceeds."
 
    As of May 31, 1998, the Company had no outstanding indebtedness under the
Bank Facility and had $25.0 million of undrawn availability thereunder. See
"Description of Bank Facility."

                     CERTAIN FINANCIAL FORECAST INFORMATION
 
GENERAL
 
    The Forecast represents the Company's best assumptions and estimates as of
March 31, 1998, of its anticipated results of operations for each of the years
in the three-year period ended December 31, 2001. The Forecast was not prepared
with a view toward compliance with published guidelines of the American
Institute of Certified Public Accounts or generally accepted accounting
principles ("GAAP"). In addition, Arthur Andersen LLP, independent accountants
for the Company, have not examined, reviewed, compiled or applied agreed-upon
procedures to the Forecast and, accordingly, assume no responsibility for and
disclaim any association with such Forecast, and no other independent expert has
reviewed the Forecast. The Forecast should be read together with the information
contained in "Disclosure Regarding Forward-Looking Statements," "Risk Factors,"
"Use of Proceeds," "Selected Financial Data," "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business."
 
    The Company will not update or otherwise revise the Forecast, including any
revisions to reflect circumstances existing after March 31, 1998, or to reflect
the occurrence of unanticipated events, even if any or all of the underlying
assumptions do not materialize. Furthermore, the Company will not update or
revise the Forecast to reflect changes in general economic or industry
conditions. The Forecast should not be relied upon for any purpose following
consummation of the Original Offering.
 
    For additional assumptions on which the Forecast information is based, see
"--Summary of Significant Assumptions for the Financial Forecast Information."
All assumptions and the Company's current and future businesses and operations
are subject to a number of uncertainties. See "Risk Factors."
 
LIMITATIONS OF FORECAST INFORMATION
 
    The Forecast is based upon a number of estimates and assumptions that, while
presented with numerical specificity and, as of March 31, 1998, considered
reasonable by management of the Company, are inherently subject to significant
business, economic, competitive, regulatory and other uncertainties and
contingencies, all of which are difficult to predict and many of which are
beyond the control of the Company. The assumptions disclosed herein are those
that the Company believes are significant to the Forecast and reflect
management's judgment as of March 31, 1998. The Forecast is necessarily
speculative in nature, and it is usually the case that one or more of the
assumptions do not materialize. Not all assumptions used in the preparation of
the Forecast have been set forth herein.
 
    The actual results achieved during the forecasted periods will vary from
those set forth in the Forecast, and those variations may be material. As
disclosed elsewhere in this Prospectus under "Risk Factors," the business and
operations of the Company are subject to substantial risks that increase the
uncertainty inherent in the Forecast. Many of the factors disclosed under "Risk
Factors" in this Prospectus could cause actual results to differ materially from
those expressed in the Forecast. The Forecast assumes the successful
implementation of the Company's business strategy, including the completion of
the construction of the Rigs on their respective Scheduled Delivery Dates with
the proceeds from the Original Offering and cash on hand. No assurance can be
given that the Company's strategy will be effective, that such construction will
be completed at the assumed construction costs or at the Rigs' respective
Scheduled Delivery Dates or at all, or that the anticipated income from the Rigs
or benefits from the Company's strategy will be realized in the period from
which the Forecast has been prepared, if ever.
 
    THE INCLUSION OF THE FORECAST HEREIN SHOULD NOT BE REGARDED AS A
REPRESENTATION BY THE COMPANY OR ANY OTHER PERSON THAT THE FORECAST WILL BE
ACHIEVED. PROSPECTIVE INVESTORS ARE CAUTIONED NOT TO PLACE UNDUE RELIANCE ON THE
FORECAST AND SHOULD MAKE THEIR OWN INDEPENDENT ASSESSMENT OF THE COMPANY'S
FUTURE RESULTS OF OPERATIONS, CASH FLOWS AND FINANCIAL CONDITION.
 
    The Forecast in general also assumes that, among other things, the Company
will not be negatively or positively affected by legal proceedings (see
"Business--Legal Proceedings"); the Company will not be
 
                                       22
<PAGE>
negatively affected by any material proceedings with respect to compliance with
environmental laws and rules; there will be no material changes in the United
States, foreign state or local tax, environmental or regulatory laws, rules or
interpretations thereof that would materially affect the Company, including, but
not limited to, those with respect to OPA '90 (as defined) (in each case, see
"Risk Factors--Environmental and Other Regulations" and "Business--Governmental
Regulations"); there will be no material change in any of the Construction
Contracts or other material contracts of the Company, and the parties thereto
will perform their obligations thereunder; there will be adequate trained
personnel available to man the Rigs at costs commensurate with the costs paid by
the Company's competitors, and no labor or industrial disputes, political unrest
or other disturbances that would materially affect the operations or revenues of
the Company, nor any disputes affecting the Company's suppliers or customers,
will occur; the Company will not make any material acquisitions or dispositions;
the Company will be able to employ the Rigs at the dayrates and at the
utilization levels assumed in the Forecast and that the Rigs can be operated at
the level of expense assumed in the Forecast; the Company will collect its
accounts receivable in a timely manner; key members of management will continue
to be employed by the Company (see "Management" and "Certain Relationships and
Related Transactions"); the Company will be able to comply with covenants under
agreements under which it will have indebtedness outstanding (see "Risk
Factors--Substantial Leverage; Ability to Service Debt"); the Company's business
will not be subject to materially adverse changes in the oil and gas industry
and the market for oil and gas production, or other macroeconomic trends; and
there will be no developments having a material adverse impact on the Company's
business.
 
PROJECTED FINANCIAL AND OPERATING DATA
 
    The Forecast set forth in the table below is derived from the forecasted
results of the Rigs, which are expected to be completed in substantial part with
the proceeds of the Original Offering. The Forecast has been developed by the
Company for the years 1999 through 2001 with the CHILES COLUMBUS assumed to
begin operations in May 1999 and the CHILES MAGELLAN assumed to begin operations
in October 1999. The Forecast has been prepared by the Company as of March 31,
1998 and represents the Company's best estimate as of such date of the Company's
projected revenues, operating expenses, net income and certain operating data
for each of the years in the three-year period ending December 31, 2001.
 
    The Forecast was prepared by the Company solely for use in connection with
the private placement of the Old Notes and not for publication or with a view to
complying with the published guidelines of the Commission regarding projections
or with the guidelines established by the American Institute of Certified Public
Accountants and is included in this Prospectus only because it was furnished to
purchasers of Old Notes. The inclusion of this information should not be
regarded as an indication that the Company or anyone who received this
information considered it a reliable predictor of future events, and this
information should not be relied on as such. This information has not been
updated subsequent to consummation of the Original Offering and will not be
updated in this Prospectus, in any supplement or amendment hereto or otherwise
in any manner.

SUMMARY OF SIGNIFICANT ASSUMPTIONS FOR THE FINANCIAL FORECAST INFORMATION
 
    CONTRACT DRILLING REVENUES.  Contract drilling revenues are calculated based
on both Rigs operating under daywork contracts at dayrates of $75,000 per day,
which is not escalated over the period covered by
 
                                       24
<PAGE>
the Forecast. Such assumption represents the Company's estimate as of March 31,
1998 of expected average dayrates over the period covered by the Forecast based
on recent contract fixings for comparable rigs of which the Company was aware as
of March 31, 1998.
 
    RIG OPERATING EXPENSES.  The Forecast assumes daily drilling operating
expenses of $17,150 per Rig. Such expenses include, among other things, amounts
payable for crew costs, maintenance, insurance, inventory, medical costs and
catering. In the Forecast, costs are assumed to escalate at a rate of 3% per
year but revenues are assumed to remain flat. The Forecast assumes that the Rigs
will operate in the Gulf of Mexico during the period covered thereby.
 
    GENERAL AND ADMINISTRATIVE EXPENSE.  The Forecast includes general and
administrative expenses of approximately $2,000 per Rig per day, which
represents the Company's estimate of likely general and administrative expenses
based on its management's past experience in the offshore contract drilling
industry. In the Forecast, costs are assumed to escalate at a rate of 3% per
year but revenues are assumed to remain flat. This amount includes expected
payments under the Services Agreement with SEACOR based on expected utilization
of SEACOR services and employees and incorporates the Company's estimate of
expenses associated with the issuance of publicly traded securities and related
securities laws reporting obligations.
 
    UTILIZATION  The Forecast assumes that the utilization rate for the Rigs
during the period covered by the Forecast will equal 98%. Over the past ten
years, the average utilization rate for comparable premium jackup rigs equalled
93% and as of March 31, 1998 it exceeded 96%. The Company's assumption of a 98%
utilization rate during the period covered by the Forecast is based on such
historical utilization rates and the Company's belief that the Rigs will be the
newest, most productive and versatile units available during such period in the
premium jackup rig segment.
 
    WORKING CAPITAL ASSUMPTIONS.  The Forecast assumes that the Company will be
required to carry unpaid contract drilling accounts payable for an average of 45
days, resulting in an average working capital requirement during the period
covered by the Forecast of $6.1 million when both Rigs are operational.
 
    DEPRECIATION AND AMORTIZATION.  Under the Forecast, the assumed construction
and outfitting cost for the Rigs of $171.3 million has been depreciated on a
straight line basis over 25 years. Depreciation is recorded based on the month
the Rig is assumed to be placed in service. As of March 31, 1998, the Company
anticipated no significant capital expenditures during the period covered by the
Forecast, which, if incurred, would increase depreciation expense and therefore
reduce operating income.
 
    INTEREST INCOME.  The Forecast assumes interest income of $0.91 million in
1999, substantially all of which is attributable to interest accruing on the
Construction Escrow Account at an assumed rate of 5% per annum. Thereafter, the
Forecast assumes interest income of $0.25 million in 2000 and $1.5 million in
2001, consisting of interest earned on cash balances maintained by the Company,
accruing in each case at an annual rate of 5%.
 
    INTEREST EXPENSE.  The Forecast assumes that the entire aggregate original
principal amount of the Old Notes will remain issued and outstanding throughout
the periods presented and that during such time the Notes will accrue interest
at a rate of 10% per annum, payable semi-annually on May 1 and November 1 of
each year. In addition, the Forecast anticipates that an initial borrowing under
the Bank Facility of $6.1 million will occur during the second quarter of 1999
and that a subsequent borrowing of $4.6 million will occur during the third
quarter of 1999. At year-end 1999, the Forecast assumes total borrowings
outstanding under the Bank Facility of $9.8 million, declining to $0.18 million
by the end of the first quarter of 2000 and fully retired during the second
quarter of 2000. All borrowings under the Bank Facility are projected to bear
interest at an annual rate of 6.95%.
 
    At maximum expected usage of the Bank Facility, the Company anticipates that
it would have unused borrowing capacity of at least half of the committed amount
thereunder. The Company's projected interest expense includes commitment fees
payable under the Bank Facility on the undrawn portion of the commitment
thereunder, which fees are payable quarterly in arrears on such undrawn amount,
at a rate of 0.25% per annum until delivery by AMFELS of the first Rig and at a
rate of 0.50% per annum thereafter.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    THE FOLLOWING DISCUSSION AND ANALYSIS SHOULD BE READ IN CONJUNCTION WITH THE
FINANCIAL STATEMENTS AND NOTES THERETO INCLUDED ELSEWHERE IN THIS PROSPECTUS.
 
OVERVIEW
 
    The Company was formed in August 1997 for the purpose of constructing,
owning and operating a fleet of state-of-the-art premium jackup offshore
drilling rigs. At formation, SEACOR contributed $8.85 million in cash to the
capital of the Company (which amount was paid directly to third parties on
behalf of the Company) and COI, LLC (an entity formed by William E. Chiles
(30%), Donald B. Gregg (7.5%), Bassoe Rig Partners Ltd. ("Bassoe") (37.5%) and
Richard and Shannon Fairbanks (25%)) ("COI") contributed $0.36 million in cash
to the capital of the Company, together with the Construction Contracts,
construction in progress, certain office equipment and other rights, properties
and liabilities with an agreed-upon value of $8.49 million. The historic cost of
such assets contributed by COI was $2.26 million. The difference between the
$8.49 million agreed-upon value and the historic cost of COI's contributed
assets, $6.23 million, has been recorded in the accompanying balance sheet as
rigs under construction and equipment. COI and a predecessor (formed in March
1997) had been organized by Mr. Chiles and its other owners for the purpose of
entering into the Construction Contracts, engaging in related rig design,
engineering, procurement and financing activities and preparing for commencement
of business operations. Pursuant to the final phase of the Equity Financing,
SEACOR contributed an additional $12.15 million in cash to the Company and $14.0
million in cash advances previously made to the Company by SEACOR, and the
Company accepted cash subscriptions for the purchase of equity interests from
institutional and individual accredited investors aggregating $20.0 million. At
March 31, 1998, the Company had cash on hand of approximately $18.8 million and
no indebtedness for borrowed money.
 
    Finance has been recently formed by the Company as a Delaware corporation
for the sole purpose of acting as co-issuer of the Notes. Finance has nominal
assets, no liabilities and does not conduct any operations. Finance will not
receive any proceeds of the Notes as such proceeds are distributed from time to
time from the Construction Escrow Account. Each Owner has been recently formed
as a Delaware limited liability company for the purpose of owning and operating
one of the Rigs. As of the date of this Prospectus, neither Finance nor either
of the Owners has any operating history. Prior to the date of the Original
Offering, the Owners and Finance each had nominal capitalization.
 
    The Company previously succeeded to all rights and obligations of COI under
the Construction Contracts and Chiles has assigned to each Owner the
Construction Contract for such Owner's Rig. In addition, the Company entered
into the Services Agreement with SEACOR. See "Certain Relationships and Related
Transactions--Services Agreement."
 
RESULTS OF OPERATIONS
 
    Since inception, the Company has engaged in no operations other than
managing construction of the Rigs and related matters. To date, the Company has
not generated any operating revenues. The Company had a net loss of
approximately $0.31 million in 1997 as a result of general and administrative
expenses and depreciation in excess of interest income. For the three months
ended March 31, 1998, the Company had net income of approximately $0.28 million
as a result of interest income in excess of general and administrative expenses.
 
    Owing to the Company's lack of significant operating history, the Company's
historical financial data may not be meaningful or indicative of future results.
The Company's results of operations in the future will depend on the earnings
from the Rigs and its level of operating expenses.
 
                                       26
<PAGE>
DEVELOPMENT STAGE COMPANY
 
    The Company has operated as a development stage company since inception by
devoting substantially all of its efforts to designing, engineering and
contracting with shipyards and vendors for the Rigs, raising capital and
securing contracts for the Rigs. The Company has not generated revenues, nor is
there any assurance that the Company will generate significant revenues in the
future. In addition, there can be no assurance that the Company will
successfully complete the transition from a development stage company to
successful operations. Additional risk factors associated with the Company's
operations include, but are not limited to, oil and gas prices, capital
expenditure plans of oil and gas operators, access to capital, completion of
construction of the Rigs and competition. As a result of the aforementioned
factors and the related uncertainties, there can be no assurance of the
Company's future success. See "Risk Factors."
 
    The Company has a loss from operations of $0.08 million and $0.38 million
for the three months ended March 31, 1998 and for the period from inception to
December 31, 1997, respectively. The Company's management is currently pursuing
a business strategy that includes obtaining drilling contracts with oil and gas
operators, employment of rig personnel, obtaining additional financing to
complete the construction of the Rigs and fund the purchase of drilling
equipment, and overseeing the construction of the Rigs and installation of the
drilling equipment. There can be no assurances that this business strategy will
be achieved. While pursuing this business strategy, the Company will experience
cash flow deficits until construction is completed and the Rigs are placed in
operation. As a result of the aforementioned factors and related uncertainties,
there is substantial doubt as to the Company's ability to continue as a going
concern. The Company's financial statements included elsewhere herein do not
include any adjustments relating to the recoverability and classification of
asset carrying amounts or the amount and classification of liabilities that
might result should be the Company be unable to continue as a going concern.
 
CAPITAL RESOURCES AND LIQUIDITY
 
    Exclusive of increases in accounts payable, the Company has had negative
operating cash flow since inception, and has financed its operations with a
combination of Member advances, the sale of equity interests in the Company and
accounts payable.
 
    From January 1, 1998 through the April 1999 Scheduled Delivery Date of the
CHILES COLUMBUS, the Company expects to incur approximately $73.0 million in
aggregate costs to complete construction and outfitting this Rig, including
internal construction costs and excluding net capitalized interest. From January
1, 1998 through the September 1999 Scheduled Delivery Date of the CHILES
MAGELLAN, the Company expects to incur approximately $73.5 million in aggregate
costs to complete construction and outfitting of this Rig, including internal
construction costs and excluding net capitalized interest. The related
Construction Contracts are fixed-price contracts and approximately 95% of the
aggregate OFE cost is fixed under firm delivery contracts with the various
vendors. The Company expects to finance these costs with the net cash proceeds
of the Equity Financing and with the net proceeds of the Original Offering and
the Bank Facility. At March 31, 1998, the Company had cash on hand of
approximately $18.8 million and no indebtedness for borrowed money.
Additionally, upon delivery of the first Rig under construction, cash flow from
operations generated by this Rig and borrowings under the Bank Facility would be
available to cover remaining construction, outfitting and overhead costs
associated with the second Rig.
 
    As of June 19, 1998, the balance of funds in the Construction Escrow Account
was $84.4 million.
 
    Because the Rigs are newbuildings, the Company does not expect to incur
material additional capital expenditures associated with the Rigs for the
foreseeable future. The Company has budgeted $0.23 million, $0.52 million and
$0.53 million for the three years ended December 31, 1999, 2000 and 2001,
respectively, for routine inspection and maintenance requirements for its Rigs,
and expects to fund these expenditures with cash flow from operations.
Additionally, the Company has not budgeted for any mobilization of either Rig
from the Gulf of Mexico to another market, which if it occurs could materially
increase rig operating expense levels, and reduce revenues while the Rig is in
transit and not working. Any unanticipated capital
 
                                       27
<PAGE>
expenditure or Rig mobilization could adversely affect cash flow from operations
and operating income in the period incurred, although the Company believes that
borrowings under the Bank Facility would be adequate to address any short-term
capital or liquidity needs created as a result of any such event.
 
    In addition to capital requirements associated with Rig construction, the
Company has significant debt service obligations, principally with respect to
the Notes. As the Notes bear interest at a rate of 10% per annum, the Company
will require $11.0 million per year to cover interest on the Notes as long as
all of the Notes are outstanding. Interest on the Notes through the first two
semi-annual interest payment dates will be paid from amounts on deposit in the
Interest Escrow Account. Thereafter, the Company expects to finance debt service
on the Notes and on borrowings outstanding under the Bank Facility from cash
flow from operations and, if necessary, additional borrowings under the Bank
Facility. At the September 1999 Scheduled Delivery Date of the CHILES MAGELLAN,
the Company anticipates that it will have undrawn committed availability under
the Bank Facility of at least half of the $25.0 million commitment thereunder.
 
    The Company projects a borrowing of approximately $6.1 million under the
Bank Facility in connection with the delivery of the CHILES COLUMBUS, scheduled
for April 1999. Proceeds of this borrowing together with a portion of the
proceeds of the Original Offering and cash flow from operations would be used to
cover start-up working capital needs in connection with commencement of
operations of this Rig. Although the Bank Facility is a committed facility, no
amounts may be borrowed thereunder until and upon the delivery of the first of
the two Rigs by AMFELS and the acceptance thereof by the Company. The entire
committed facility amount of $25.0 million would be available at delivery by
AMFELS of the first Rig, subject to satisfaction of certain other conditions
precedent provided for under the Bank Facility. See "Description of Bank
Facility."
 
    The Company believes that cash flow from operations will be sufficient to
retire all indebtedness under the Bank Facility by the second quarter of 2000,
assuming that the Rigs are delivered at their respective Scheduled Delivery
Dates and promptly commence working at expected dayrate and operating expense
levels. The Company expects to finance start-up working capital needs associated
with commencement of operations of the second Rig to be delivered out of cash
flow from operations and, if necessary, additional borrowings under the Bank
Facility.
 
RECENT DEVELOPMENTS
 
    The Original Offering was consummated on April 29, 1998. See "Prospectus
Summary--The Financing" and "Use of Proceeds." In addition, the Company entered
into the Bank Facility on the Issue Date. See "Description of Bank Facility."

                                    BUSINESS
 
THE COMPANY
 
    The Company was formed in 1997 for the purpose of constructing, owning and
operating a fleet of state-of-the-art premium jackup offshore rigs. In 1997, the
Company commenced construction of the first two such rigs at the AMFELS shipyard
in Brownsville, Texas under fixed-price contracts. The first Rig, the CHILES
COLUMBUS, is a LeTourneau Enhanced 116-C design and the second, the CHILES
MAGELLAN, is a LeTourneau Super 116 design. The Company expects that it will
pay, net of capitalized interest, $83.5 million and $87.8 million, respectively,
in total construction and outfitting costs for the Rigs. The Company and AMFELS
have scheduled the Rigs for delivery in April and September 1999, respectively.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operation--Overview." Chiles also holds three sequential Construction Options to
construct additional LeTourneau Super 116 design jackup rigs at a total cost of
approximately $100.0 million per rig. See "--The Construction Options."
 
    SEACOR, operator of the second largest fleet of offshore service vessels in
the world, has invested $35.0 million for approximately 55.4% of the outstanding
equity interests in the Company. SEACOR is a Delaware corporation whose common
stock is listed for trading on the New York Stock Exchange under the symbol
"CKH." The remaining equity interests in the Company are held by private
investors, including the original founders and senior management. See "Principal
Members" and "Certain Relationships and Related Transactions--Brokerage Fee."
 
    The Company's management team has extensive experience in the offshore
contract drilling industry. William E. Chiles, the President and CEO of the
Company, has over 25 years of experience in the industry. During his career Mr.
Chiles founded or co-founded three offshore contract drilling companies and
supervised the construction of four jackup rigs at the Brownsville, Texas
shipyard facility where the two Rigs are being constructed. The Company's
operating and engineering personnel have substantial experience operating,
marketing, building, refurbishing and upgrading premium jackup rigs, including
the LeTourneau 116-C design.
 
THE RIGS
 
    Jackup rigs are the largest category of mobile offshore drilling units,
representing approximately 60% of such units. A mobile offshore drilling unit
consists of a drilling package mounted on a hull, which is maintained at a
specific location during drilling operations. The drilling package typically
consists of a power plant, hoisting equipment, a rotary system, tubulars and
systems for mud treating and pumping, well control and the handling of bulk
materials. The specifications of the drilling package determine the capability
of the rig to drill to various depths and penetrate certain sub-surface
environments. The drilling unit also includes the living quarters, heliport,
cranes and tensioning and compensation systems of the drilling package. The
design of the particular drilling unit determines the marine environment in
which it can operate.
 
    Several factors determine the type of rig most suitable for a particular
project, the more significant of which are the marine environment, water depth
and seabed conditions at the proposed drilling location, whether the drilling is
being done over a platform or other structure, the intended well depth and
variable deck load and well control requirements. Considerable variation in
utilization and dayrates often exists for different types of rigs, primarily as
a function of their capabilities and location.
 
    Jackup rigs are mobile, self-elevating drilling platforms equipped with legs
that are lowered to the ocean floor until a foundation is established to support
the drilling platform. A jackup rig consists of the hull, jacking system,
drilling equipment, crew quarters, loading and unloading facilities, storage
areas, heliport and other related equipment. Oil and gas exploration companies
use jackup rigs extensively for offshore drilling in water depths from 20 feet
to 350 feet. A jackup rig is towed to the drillsite with its hull
 
                                       29
<PAGE>
riding in the sea and its legs retracted. At the drillsite, the legs are jacked
down to the ocean floor until the hull has been elevated a sufficient distance
above the water to allow storm waves to pass beneath. After completion of
drilling operations, the hull is lowered until it rests in the water and then
the legs are retracted for relocation to another drillsite.
 
    The nature of the seabed at a particular drilling location dictates the
appropriate rig-leg configuration of the jackup rig to be used. Some jackup rigs
have a lower hull (mat) attached to the bottom of the rig legs, while others
have independent legs. A mat-supported rig provides a stable foundation in flat
soft-bottom areas, while independent-leg rigs are better suited for harder or
uneven seabed conditions.
 
    Jackup rigs can be generally characterized as either slot jackup rigs or
cantilevered jackup rigs. Slot-design rigs are configured for drilling
operations to take place through a slot in the hull. A slot design is
appropriate for drilling exploratory wells in the absence of any existing
permanent structure, such as a production platform, although some slot design
rigs are capable of drilling over certain production platforms. A cantilevered
jackup rig can extend its drill floor and derrick over an existing, fixed
structure, thereby permitting the rig to drill or work over a well located on
such a structure.
 
    Jackup rigs vary a great deal in size and capability. The Company defines
premium jackup rigs as cantilevered jackup rigs capable of operating in water
depths of 300 feet or greater, excluding (due to their substantially higher
construction cost) the class of jackup rigs built for service in "harsh
environments," such as the North Sea and Eastern Canada.

    The Rigs to be constructed by the Company consist of one LeTourneau Enhanced
116-C jackup rig and one LeTourneau Super 116 jackup rig, both of which are
improved versions of the most versatile and popular design in the worldwide
jackup rig fleet (the LeTourneau 116-C). The hulls, machinery and outfitting are
identical on the two Rigs and are based on the larger LeTourneau Super 116
design. The only difference is that the LeTourneau Super 116 design has a leg
that has been designed to a higher specification while the LeTourneau Enhanced
116-C design is based on a LeTourneau 116-C design that has subsequently been
strengthened to carry the larger LeTourneau Super 116 hull and longer legs. The
Rigs will have capabilities that substantially exceed those of typical existing
premium jackup rigs, including increased engine horsepower, increased hydraulic
horsepower and an enlarged mud handling and solids control system. The Rigs will
also incorporate such features as digital drilling controls, dual pipe handling,
pipe handling robotics, and a drillpipe identification and tracking system. The
Rigs will further differentiate themselves by their increased productivity, due
mainly to their superior engine and hydraulic horsepower.

    It is anticipated that the Rigs will fly the Panamanian flag, with an
"A1--Self Elevating Drilling Unit" certification from the American Bureau of
Shipping.
 
RIG PRODUCTIVITY ENHANCEMENTS
 
    The Rigs contain numerous productivity-enhancing features that the Company
believes make their capabilities superior to those of existing premium jackup
rigs. A hydraulic horsepower of two times the typical premium jackup rig (6,600
hp vs. 3,200 hp) increases drilling performance. The higher horsepower increases
pressure at the drill bit, leading to faster drilling. The larger mud pump
system capacity (three mud pumps versus a standard of two) coupled with
increased solids control capacity allows for faster circulation of cuttings and
a quicker cleaning of mud resulting in more productive drilling. The extended
cantilevering capability permits the drilling package to extend up to 70 feet
from the hull without moving the Rig.
 
    The Company expects that the technological sophistication of the systems
available on the Rigs will result in improved performance. Fiber optics wiring
and an internet connection will provide customers timely information about Rig,
well and equipment performance, and also enable equipment vendors and other
service providers to diagnose equipment problems remotely. The drillpipe
identification and tracking system tracks the number of feet drilled by each
section of drillpipe and identifies the joints that require inspection rather
than the entire drillstring, thus decreasing the cost and frequency of mandatory
inspections of drillpipe. The "Iron Roughneck" robot performs the work of three
people in connecting and disconnecting new joints of drillpipe, increasing the
speed of drilling and improving safety. Powerslips replace the need for crew to
manually set slips to hold the drillstem in place. The dual pipehandling system
allows for the assemblage of the 90-foot "stands" of drillpipe (made up of three
individual 30-foot joints) that are required for the Rigs' top-drive drilling
systems as drilling is taking place. When moving to a new drilling location,
higher capacity water pumps fill the hull with water faster to settle the legs
into the sea bottom, expediting the preparation for the drilling process. The
new design of the blowout preventers, which must be installed three or four
times for a typical Gulf of Mexico well, reduces their installation time from
approximately 10 to 12 hours to three to four hours.
 
    The Company believes that its focus on construction utilizing the proven
LeTourneau 116-C design, but with the addition of an enhanced equipment package
compared to existing rigs of this design, should provide the Company with a
competitive advantage, particularly in bidding for horizontal and extended reach
drilling projects. The Company expects that the increased drilling efficiencies
attributable to these enhancements may enable the Company to bid more
aggressively on incentive-based contracts, as opposed to standard dayrate
contracts, where profit potential may be greater.
 
MARKET OVERVIEW
 
    The demand for offshore drilling services is substantially dependent upon
the continued exploration for and development of hydrocarbons in geological
formations offshore. In the early 1980s, in the aftermath of the second oil
price shock, it was anticipated that oil prices would rise substantially. This
was the basis for the dramatic newbuilding activity that followed, which
resulted in the construction of 236 rigs between 1980 and 1983. Oversupply of
rigs caused worldwide rig utilization to decline rapidly thereafter and
substantially depressed the offshore contract drilling market until the
beginning of the 1990s. During the last two to three years, global demand for
offshore drilling equipment has increased to the point of finally absorbing the
excess capacity created out of the substantial newbuilding activity of the early
1980s.

    Based on published industry data, the Company estimates that, as of March
31, 1998, the average dayrate for premium jackup rigs worldwide was $73,000 and
that it averaged $62,000 in 1997 and $39,000 in 1996. (1997 and 1996 dayrate
data include a small number of "harsh environment" jackup rigs, which increases
slightly the average historical dayrate information for premium jackup rigs.)
Based on published industry data, the Company estimates that premium jackup rig
utilization levels have averaged 93% over the last ten years and that, as of
March 31, 1998, average utilization exceeded 96%. The major factors underlying
these improvements are an increase in demand, due to greater offshore
exploration and development expenditures by the world's oil and gas companies,
and a reduction in rig supply, due to the advancing age of the existing fleet
and the small number of newbuildings. Growth in offshore expenditures by oil and
gas companies has been due in part to substantial technological advances in
exploration and production (including 3-D seismic, horizontal drilling and
subsea completion procedures), which have reduced the overall cost of finding
and producing oil and gas. In addition, the offshore drilling industry has
experienced a worldwide consolidation during the last ten years which has
substantially reduced the number of drilling contractors. See "Risk
Factors--Dependence on Oil and Natural Gas Industry; Industry Conditions; Market
Volatility."
 
    The world's offshore drilling rig fleet has declined in size to the point at
which current demand yields high utilization, and consequently high dayrates,
which creates the conditions necessary to support a demand-driven renewal of the
fleet. In addition, structural changes in the worldwide exploration and
production industry have brought the offshore contract drilling market to the
beginning of a cycle that the Company believes justifies the economics of
building new premium jackup rigs to serve the industry into the next century.
The world's jackup rig fleet currently consists of 380 rigs, which vary
significantly in terms of technological advancement, water depth capability and
age. A total of 117 are premium jackup rigs and as of March 1998, 29 such rigs
were employed in the Gulf of Mexico, the largest single market for jackup rigs.
The current average age of the world's jackup rig fleet is 17.5 years with
premium jackup rigs having an average age of 16.4 years, which compares to an
expected original useful life for such units of approximately 25 years. In
addition to the Company's Rigs, seven other jackup rig newbuildings are on order
with shipyards around the world (collectively representing 2.4% of the existing
fleet), of which six are jackup rigs designed for work in "harsh environment"
areas.

BUSINESS STRATEGY
 
    The Company intends to become a leading provider of state-of-the-art premium
jackup rigs and to maximize dayrates and rig utilization by offering its
customers the most productive premium jackup rigs available. The Company will
focus on establishing a reputation for customer service, higher productivity and
safety of operation in the offshore contract drilling market. The key elements
of the Company's strategy are as follows:
 
    - FOCUS ON PREMIUM JACKUP RIG MARKET. The Company will focus on premium
      jackup rigs, which the Company believes enjoy strong and growing worldwide
      demand, have the versatility to work in a variety of different markets,
      represent a relatively low investment compared to new semisubmersibles,
      drillships and "harsh environment" jackup rigs, possess a favorable
      relationship between potential revenues and operating costs, and are
      familiar to the management of the Company through prior operations and
      newbuildings.
 
    - OWN AND OPERATE HIGH QUALITY ASSETS. The Rigs will represent a new
      generation of premium jackup rigs with significantly enhanced capabilities
      incorporating the latest technologies. Such capabilities will assist the
      Company in offering its customers equipment with superior productivity and
      safety features.
 
    - BUILD TO MEET STRONG DEMAND GROWTH. The Company intends to be among the
      first offshore drilling contractors to provide new generation premium
      jackup rigs to the industry. The Company believes that this is the early
      stage of a period of strong growth in the demand for, and utilization of,
      premium jackup rigs. The Company believes that it has been able to secure
      favorable contract terms by placing orders during this early stage, at a
      time when relatively few new premium jackup rigs are being built.
 
    - EXPAND RIG FLEET. The Company expects to expand its rig fleet prudently
      over time. The Company may achieve this growth through the exercise of
      three Construction Options that the Company holds to construct additional
      LeTourneau Super 116 design premium jackup rigs at a total delivered cost
      of approximately $100.0 million per rig.
 
    - FOCUS ON THE GULF OF MEXICO. The Company will focus its operations
      initially on the Gulf of Mexico market, which is the largest single market
      for jackup rigs in the world. Furthermore, the presence of an established
      pipeline and production infrastructure makes the Gulf of Mexico an
      economically attractive market for continued exploration and production
      activity.
 
                                       33
<PAGE>
    - UTILIZE SEACOR EXPERTISE. SEACOR will directly advise the Company
      concerning strategic, financial and marketing matters through
      representation on the Company's Management Committee (I.E., its board of
      directors). Additionally, pursuant to the Services Agreement, SEACOR has
      made available its Vice President, Finance to serve as the Company's
      Senior Vice President and Chief Financial Officer. The Company believes
      that SEACOR's marketing expertise and its extensive oil and gas company
      client base will greatly assist the Company in the marketing of the Rigs.
 
    - EMPLOY, RETAIN AND MOTIVATE EXPERIENCED AND INCENTIVIZED MANAGEMENT. The
      Company will seek to employ, retain and motivate experienced senior
      management and key employees through the implementation of an equity
      participation and performance incentive program.
 
THE CONSTRUCTION CONTRACTS
 
    SHIPYARD.  The AMFELS shipyard, originally built and operated by Marathon
LeTourneau, Inc., has a long-term commitment to the offshore drilling industry
and many of the key personnel who designed and built LeTourneau jackup rigs in
the past are currently working there. The shipyard's newbuilding construction
experience includes 24 jackup rigs and two semisubmersibles. AMFELS is 100%
owned by Keppel FELS, Ltd., an established international shipyard and
engineering group based in Singapore.
 
    SCHEDULED DELIVERY DATES.  The Scheduled Delivery Dates of the Rigs will be
staggered. The Scheduled Delivery Date of the CHILES COLUMBUS is April 30, 1999
and the Scheduled Delivery Date of the CHILES MAGELLAN is September 10, 1999;
PROVIDED, HOWEVER, that the Scheduled Delivery Date will be extended by the
applicable period in the event of any delay caused by act or omission of the
Company, including failure to timely deliver to AMFELS any equipment to be
furnished by the Company, delays caused by the American Bureau of Shipping or
any governmental agency, changes, events of FORCE MAJEURE under the applicable
Construction Contract, or inability or failure of LeTourneau to perform its
obligations under the applicable (i) License Agreement or (ii) Kit Construction
Agreement, in each case between AMFELS and LeTourneau and dated April 30, 1997
(with respect to the CHILES COLUMBUS) and August 1, 1997 (with respect to the
CHILES MAGELLAN) (collectively, the "LeTourneau Agreements"), or if all subjects
and conditions under the applicable LeTourneau Agreements are not fully and
timely met. In addition, the Company has procured "delay-in-delivery" insurance
that provides for coverage of $30,000 per day per Rig up to a maximum of 360
days for delays in excess of 30 days up to a total combined limit of $21.6
million for both Rigs. Generally, such insurance provides coverage in the event
of delays resulting from certain events, including physical loss or damage to
the Rigs or the AMFELS shipyard during construction as a result of named perils,
including labor disturbances; delays in delivery of materials required for
construction as a result of such events; and delays resulting from restricted
access to the shipyard as a result of such events. However, the coverage
provided under such insurance is subject to significant exceptions and would not
provide protection against certain delays in delivery.
 
    PURCHASE PRICE.  The construction costs for the CHILES COLUMBUS are expected
to be approximately $83.5 million and the construction costs for the CHILES
MAGELLAN are expected to be approximately $87.8 million, in each case net of
capitalized interest.
 
    TERMINATION OF THE CONSTRUCTION CONTRACTS.  The Company may terminate a
Construction Contract upon the occurrence of certain events of default by
AMFELS. The events of default include the failure by AMFELS to perform, or the
breach by AMFELS of, any of its covenants, agreements or undertakings under the
applicable Construction Contract which AMFELS has failed to commence diligently
to cure within thirty (30) days or which remains uncured for ninety (90) days,
in each case after notice thereof by the Company to AMFELS, including such a
failure to deliver the respective Rig by its Scheduled Delivery Date.
 
    In addition, a Construction Contract will be automatically terminated if,
prior to delivery of the related Rig, an actual or constructive total loss
occurs with respect to such Rig.
 
                                       34
<PAGE>
    WARRANTY OF QUALITY.  For a period of 12 months following the date of
delivery of a Rig, AMFELS warrants to the Company that (i) AMFELS's workmanship
and materials shall be free from material defects, (ii) that systems designed,
supplied and installed by AMFELS will perform the functions intended by the
applicable Construction Contract and the specifications thereunder, and (iii)
that the components of the equipment manufactured by LeTourneau shall be free
from material defects in LeTourneau's workmanship and material and shall perform
in accordance with the applicable LeTourneau Agreement and the related
specifications (the "Warranty"). The Warranty commences on the date of delivery
of the applicable Rig to the Company and expires 12 months thereafter (provided,
however, that if any of the equipment of the Rig is put into service prior to
such delivery, the Warranty period begins with the commencement of such service
or operation insofar as such equipment is concerned) and is subject to certain
limitations set forth in the applicable Construction Contract.
 
    The Warranty does not apply to any part of a Rig which has been misused, or
structurally repaired or altered by anyone other than AMFELS or its duly
authorized representative, or has been damaged because of its use, or the use of
any other materials or equipment, after the Company (or any other person or firm
operating the Rig or its equipment) has knowledge of such defect. Except for
certain components of the equipment manufactured by LeTourneau, equipment or
other components of the Rig sold to the Company pursuant to the Construction
Contract but not manufactured by AMFELS are not warranted to any extent by
AMFELS.
 
    Pursuant to the Assignment, Assumption, Acknowledgement and Consent
Agreement, dated as of April 23, 1998, among the Company, the Owners and AMFELS,
the Company assigned to each Owner the Construction Contract for such Owner's
Rig.
 
THE CONSTRUCTION OPTIONS
 
    The Company holds three sequential Construction Options for the following
rigs (collectively, the "Option Rigs") pursuant to an agreement, dated December
18, 1997 (the "Option Agreement"), with AMFELS: (i) a LeTourneau Super 116
("Option Rig No. 1"), which option will expire on July 31, 1998; (ii) contingent
upon the Company's entering into a construction contract for Option Rig No. 1,
one sister rig ("Option Rig No. 2"), which option must be exercised prior to
December 15, 1998; and (iii) contingent upon the Company's entering into a
construction contract for Option Rig No. 2, one sister rig, which option must be
exercised prior to March 31, 1999.
 
    In the Option Agreement, AMFELS and the Company agreed to enter into an
amendment of the Construction Contract for the CHILES MAGELLAN to reflect the
terms of the Option Agreement to, among other things, provide for the ability to
provide a construction lender with a first preferred security interest in the
Option Rigs during the construction period.
 
    In the Option Agreement, the Company agreed that as long as any Construction
Option remains outstanding and in effect, the Company will not order any similar
premium jackup rigs at a competing shipyard without first having received
AMFELS's approval in writing and that AMFELS will supply the requirements of the
Company for LeTourneau premium jackup rigs as contemplated by the Option
Agreement.
 
    The Company estimates that it would incur total average costs of
approximately $100.0 million to construct and outfit each rig pursuant to the
exercise of any Construction Option, which includes construction costs payable
to AMFELS, the expected price of the required LeTourneau "Kit," costs of related
OFE, construction overhead and capitalized interest.
 
COMPETITION
 
    The contract drilling industry is highly competitive. Customers sometimes
award contracts on a competitive bid basis, and although a customer selecting a
rig may consider, among other things, a
 
                                       35
<PAGE>
contractor's safety record, crew quality and quality of service and equipment,
price is the major factor in determining the selection of a drilling contractor.
The Company believes that competition for drilling contracts will continue to be
intense for the foreseeable future because of the ability of contractors to move
rigs from areas of low utilization and dayrates to areas of greater activity and
relatively higher dayrates. Such movement or a decrease in drilling activity in
any major market could depress dayrates and could adversely affect utilization
of the Company's Rigs. See "--Offshore Contract Drilling Services."
 
OFFSHORE CONTRACT DRILLING SERVICES
 
    The Company's contracts to provide offshore drilling services are expected
to vary in their terms and provisions. The Company expects that it may obtain
contracts through competitive bidding, although the Company may also be awarded
drilling contracts without competitive bidding. Drilling contracts generally
provide for a basic drilling rate on a fixed dayrate basis regardless of whether
such drilling results in a successful well. Drilling contracts may also provide
for lower rates during periods when the rig is being moved or when drilling
operations are interrupted or restricted by equipment breakdowns, adverse
weather or water conditions or other conditions beyond the control of the
Company. Under dayrate contracts, the Company would generally expect to pay the
operating expenses of the rig, including wages and the cost of incidental
supplies. Revenues from dayrate contracts are expected to account for a
substantial portion of the Company's revenues. In addition, the Company may work
a Rig under dayrate contracts pursuant to which the customer also agrees to pay
the Company an incentive bonus based upon performance.
 
    A dayrate drilling contract generally extends over a period of time covering
either the drilling of a single well, a group of wells (a "well-to-well
contract") or a stated term (a "term contract") and may be terminated by the
customer in the event the drilling unit is destroyed or lost or if drilling
operations are suspended for a specified period of time as a result of a
breakdown of major equipment or in some cases due to other events beyond the
control of either party. In addition, it is expected that certain of the
Company's contracts may permit the customer to terminate the contract early by
giving notice and in some circumstances may require the payment of an early
termination fee by the customer. The contract term in many instances may be
extended by the customer exercising options for the drilling of additional wells
at fixed or mutually agreed terms, including dayrates.
 
    The duration of offshore drilling contracts is generally determined by
market demand and the respective management strategy of the offshore drilling
contractor and its customers. In periods of rising demand for offshore rigs,
contractors typically prefer well-to-well contracts that give contractors the
flexibility to profit from increasing dayrates. In contrast, during these
periods customers with reasonably definite drilling programs typically prefer
longer term contracts to maintain drilling prices at the lowest level possible.
Conversely, in periods of decreasing demand for offshore rigs, contractors
generally prefer longer term contracts to preserve dayrates at existing levels
and ensure utilization, while the customers prefer well-to-well contracts that
allow them to obtain the benefit of lower dayrates. In general, the Company
expects to seek to have a reasonable balance of single well, well-to-well and
term contracts to minimize the downside impact of a decline in the market while
still participating in the benefit of increasing dayrates in a rising market.
 
QUALITY
 
    The Company expects to maintain a program to continuously improve quality
and safety on the Rigs and to foster a commitment to quality of service, safety
and the environment. It is expected that the Company's quality system will
provide for formal procedures to assist in continuous improvement in the
Company's efforts to exceed customer expectations in safety, environmental
concerns, equipment maintenance, rig enhancements, material handling and
personnel training and performance.
 
                                       36
<PAGE>
GOVERNMENTAL REGULATION
 
    The Company's operations will be subject to numerous federal, state and
local environmental laws and regulations that relate directly or indirectly to
its operations, including certain regulations controlling the discharge of
materials into the environment, requiring removal and clean-up under certain
circumstances, or otherwise relating to the protection of the environment. For
example, the Company may be liable for damages and costs incurred in connection
with oil spills for which it is held responsible. Laws and regulations
protecting the environment have become increasingly stringent in recent years
and may in certain circumstances impose "strict liability" and render 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 United States Oil Pollution Act of 1990 ("OPA '90") and similar
legislation enacted in Texas, Louisiana and other coastal states address oil
spill prevention and control and significantly expand liability exposure across
all segments of the oil and gas industry. OPA '90, such similar legislation and
related regulations impose a variety of obligations on the Company related to
the prevention of oil spills and liability for damages resulting from such
spills. OPA '90 imposes strict, and with limited exceptions, joint and several
liability upon each responsible party for oil removal costs and a variety of
public and private damages. OPA '90 also imposes ongoing financial
responsibility requirements on a responsible party. A failure to comply with
such ongoing requirements or inadequate cooperation in a spill may subject a
responsible party, including in some cases the Company, to civil or criminal
enforcement action. OPA '90 also requires the U.S. Minerals Management Service
to promulgate regulations to implement the financial responsibility requirements
for offshore facilities. If implemented as written, the financial responsibility
requirements of OPA '90 could have the effect of significantly increasing the
amount of financial responsibility that oil and gas operators must demonstrate
to comply with OPA '90. While industry groups and marine insurance carriers are
seeking modification of these requirements, implementation of these requirements
in their current form could adversely affect the ability of some of the
Company's prospective customers to operate in U.S. waters, which could have a
material adverse effect on the Company.
 
    The Federal Water Pollution Control Act of 1972, commonly referred to as the
Clean Water Act ("CWA"), prohibits the discharge of certain substances into the
navigable waters of the U.S. without a permit. The regulations implementing the
CWA require permits to be obtained by an operator before certain exploration or
drilling activities occur. Violations of monitoring, reporting and permitting
requirements can result in the imposition of civil and criminal penalties. The
provisions of the CWA can also be enforced by citizens' groups. Many states have
similar laws and regulations.
 
    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. Violation 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.
 
    The Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended ("CERCLA"), currently exempts crude oil, and the Resource
Conservation and Recovery Act, as amended ("RCRA"), currently exempts certain
drilling materials, such as drilling fluids and production waters, from the
definitions of hazardous substances and hazardous wastes. However, the Company's
operations may involve the use or handling of other materials, such as
fracturing fluids or acids, that may be classified as environmentally hazardous
substances or wastes. There can be no assurance that such exemption will be
preserved in future amendments of such acts, if any, or that more stringent laws
and regulations protecting
 
                                       37
<PAGE>
the environment will not be adopted. CERCLA assigns strict liability to each
responsible party, as defined, for all response and remediation costs, as well
as natural resource damages. Few defenses exist to the liability imposed by
CERCLA.
 
    The Company's operations may involve the generation, use or handling of
materials, such as unused fracturing fluids or acids, that may be classified as
hazardous waste, and that are subject to RCRA and comparable state statutes. The
Environmental Protection Agency ("EPA") and various state agencies have limited
the disposal options for certain hazardous and nonhazardous wastes and are
considering the adoption of stricter handling and disposal standards for
nonhazardous wastes. RCRA currently exempts certain drilling materials, such as
drilling fluids and production waters, from the definitions of hazardous wastes.
There can be no assurance that such exemption will be preserved in future
amendments of such acts, if any, or that more stringent laws and regulations
protecting the environment will not be adopted.
 
    The operations of the Company are subject to the Clean Air Act, as amended,
and comparable state statutes. Traditional air quality programs relating to the
prevention of significant deterioration of air quality in areas with
unacceptable pollution levels ("nonattainment areas") restrict drilling in
affected areas. Amendments to the Clean Air Act were adopted in 1990 and contain
provisions that may result in the imposition over the next decade of certain
requirements with respect to air emissions, which requirements may require
capital expenditures by the Company. The EPA is currently developing regulations
to implement these requirements. Pursuant to a mandate of the Clean Air Act, the
EPA, together with other agencies of the federal government, is conducting a
study of the effects of emissions from drilling activities in nonattainment
areas on the Outer Continental Shelf. Upon completion of the study, these
agencies will determine whether additional regulatory requirements are necessary
for these nonattainment areas. Any greater degree of regulation in nonattainment
areas would increase the cost associated with operation in those areas.
 
INDEMNIFICATION AND INSURANCE
 
    The Company generally expects to be able to obtain contractual
indemnification pursuant to which the Company's customers would agree to protect
and indemnify the Company to some degree from liability for reservoir, pollution
and environmental damages, but there can be no assurance that the Company can
obtain such indemnities in all of its contracts, that the level of
indemnification that can be obtained will be meaningful, that such
indemnification agreements will be enforceable or that the customer will be
financially able to comply with its indemnity obligations. In addition, the
Company expects to maintain insurance coverage against "loss-of-hire," property
damage, war risk (in the case of certain operations outside the U.S.), general
liability and environmental liabilities, including pollution caused by sudden
and accidental oil spills, 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 loss or liability in many
circumstances. Moreover, any such insurance is expected to be subject to
substantial deductibles and to provide for premium adjustments based on claims.

    The Company leases approximately 4,500 square feet of office space located
at 11200 Westheimer, Suite 410, Houston, Texas 77042-3227, where its telephone

- ------------------------
 
(1) Pursuant to Instruction 1 to Item 402(a)(3) of Regulation S-K, no disclosure
    is provided for any other executive officer of the Company because no other
    executive officer of the Company had total annual salary and bonus in excess
    of $100,000 for the fiscal year ended December 31, 1997.
 
(2) Amounts exclude perquisites and other personal benefits because such
    compensation did not exceed the lesser of $50,000 or 10% of the total annual
    salary reported for the Named Executive Officer.
 
(3) The amount shown was paid for life insurance.
 
    Effective May 1, 1998, the Company adopted a defined contribution plan (the
"Retirement Plan"), designed to qualify under Section 401(k) of the Code,
covering substantially all of its employees. Pursuant to the Retirement Plan,
the Company will match employees' contributions to the Retirement Plan in an
amount equal to 50% of such contributions, up to 6% of the participant's
eligible compensation.
 
EMPLOYMENT AGREEMENT
 
    William E. Chiles is presently serving as President and Chief Executive
Officer of the Company under an Employment Agreement, effective as of November
1, 1997, between Mr. Chiles and the Company (the "Employment Agreement"),
pursuant to which Mr. Chiles will continue to serve in such capacity until
November 2000 at his current base salary of $200,000 per annum. The Employment
Agreement also provides Mr. Chiles with severance benefits, disability and
health insurance, approximately $1.2 million in term life insurance,
reimbursement for various expenses and such other compensation, including
bonuses, that may be agreed to by the Management Committee of Chiles, in its
sole discretion. Under the Employment Agreement, Mr. Chiles's salary will be
reviewed for adjustment annually in accordance with industry standards, taking
into account his performance, the Company's scope of operations, industry
conditions and the overall performance of the Company relative to its peers.
 
MEMBERSHIP INTEREST OPTION PLAN
 
    The Company recently adopted the Chiles Offshore LLC 1998 Equity Option Plan
(the "Option Plan"). The objectives of the Option Plan are (i) to attract and
retain management personnel with the training, experience and ability to enable
them to make a substantial contribution to the success of the Company's
business, (ii) to motivate management personnel by means of growth-related
incentives to achieve long range goals and (iii) to further the alignment of
interests of participants with those of the Company's equity holders through
opportunities for increased equity or equity-based ownership in the Company.
 
    The Option Plan authorizes the issuance of options to acquire up to 5.0% of
the then outstanding Membership Interests on a fully diluted basis, without
triggering pre-emptive rights under the Operating Agreement, so long as such
options are exercisable at a price that is not less than the price per
percentage Membership Interest paid in the Equity Financing. The Option Plan is
administered by an Option Committee of the Management Committee of Chiles (the
"Option Committee"). Pursuant to the Option Plan, the Company may grant to key
employees and consultants of the Company or any of the Company's subsidiaries
options to acquire Group D Membership Interests. Such options are not considered
incentive stock options under Section 422 of the Internal Revenue Code of 1986,
as amended (the "Code"). The terms of any such grant will be determined by the
Option Committee and set forth in a separate grant agreement except for such
options that were granted to employees under an Initial Grant (as defined in
 
                                       40
<PAGE>
the Option Plan). The Option Plan sets forth the exercise price and maximum
amount of the Initial Grant. Other than the Initial Grant, the exercise price
will be at least equal to 100% of the fair market value of the Membership
Interests on the date of grant.
 
    The Option Committee may provide that an optionee may pay for shares upon
exercise of an option: (i) in cash; (ii) by certified bank check; (iii) by
immediately available federal funds delivered to an account designated by the
Company; or (iv) by personal check of the optionee, provided that such check
will not be deemed to have been received until the Company shall have collected
thereon. The options expire ten years after the date of grant. No options
granted under the Option Plan may be transferred except under limited exceptions
to family members or trusts for the benefit of family members. See "Certain
Relationships and Related Transactions--Option Repurchase Obligation."
 
    The following table sets forth the options to acquire Membership Interests
in the Company that were outstanding as of March 31, 1998, all of which
constitute Initial Grants under the Option Plan:

(1) One "unit" is equivalent to a .001 Membership Interest in the Company on a
    fully diluted basis. The Option Plan authorizes the issuance of options to
    acquire up to 5,000 such "units" which, in the aggregate, are equivalent to
    5.0% of the Membership Interests in the Company on a fully diluted basis. As
    of March 31, 1998, options for 947 "units" were reserved for future Rig
    supervisors and options for 100 "units" were reserved for other future
    personnel.
 
(2) The percentage is based on the total of 5,000 "units" for which options may
    be granted under the Option Plan. As of March 31, 1998, the options for 947
    "units" reserved for issuance to future Rig supervisors constitute 18.94% of
    such total number of "units" and the options for 100 "units" reserved for
    issuance to other future personnel constitute 2.00% of such total number of
    "units"
 
(3) The exercise price is approximately equivalent to the price per "unit" paid
    by investors on December 16, 1997 in connection with the final phase of the
    Equity Financing.
 
(4) The options vest at a rate of 1/3 of the "units" granted per year, beginning
    on the first anniversary of the date of grant. No option may be exercised
    unless and until both of the Rigs are delivered by AMFELS and accepted by
    the Company.
 
MANAGEMENT COMMITTEE
 
    The Management Committee of Chiles presently consists of seven Managers.

THE EQUITY FINANCING
 
    The Company was formed in August 1997 for the purpose of constructing,
owning and operating a fleet of state-of-the-art premium jackup offshore
drilling rigs. At formation, SEACOR contributed $8.85 million in cash to the
capital of the Company (which amount was paid directly to third parties on
behalf of the Company) and COI contributed $0.36 million in cash to the capital
of the Company, together with the Construction Contracts, construction in
progress, certain office equipment and other rights, properties and liabilities
with an agreed-upon value of $8.49 million. The historic cost of such assets
contributed by COI was $2.26 million. The difference between the $8.49 million
agreed-upon value and the historic cost of COI's contributed assets, $6.23
million, has been recorded in the accompanying balance sheet as rigs under
construction and equipment. COI and a predecessor (formed in March 1997) had
been organized by Mr. Chiles and its other owners for the purpose of entering

majority of the Membership Interests in Chiles, SEACOR Rigs, which is controlled
by SEACOR, will be in a position to control actions that require consent of a
Majority in Interest (as defined in the Operating Agreement) of the Members of
Chiles, and, by virtue of the terms of the Operating Agreement, SEACOR Rigs has

offshore West Africa, Mexico, the Far East, Latin America and the Mediterranean.
SEACOR's offshore service vessels deliver cargo and personnel to offshore
installments, handle anchors for drilling rigs and other marine equipment,
support offshore construction and maintenance work and provide standby support.
SEACOR also furnishes vessels for special projects such as well stimulation,
seismic data gathering, freight hauling and line handling. In connection with
its offshore marine services, SEACOR, through Energy Logistics, Inc., a joint
venture with Baker Energy, a unit of the Michael Baker Corporation, a U.S.
public company, also offers logistics services for the offshore industry,
including the coordination and provision of marine, air and land transportation,

<PAGE>
the capitalization of the Company and the Company will pay SEACOR a management
fee for the value of Mr. Fagerstal's services (together with reimbursement of
all related out-of-pocket expenses) based on a formula which will, among other
things, take into account the typical compensation for this position and the
percentage of Mr. Fagerstal's time which is allocated to activities related to
the Company.
 
    Charles Fabrikant, the Chairman and CEO of SEACOR, serves as the Chairman of
the Management Committee of the Company. Randall Blank, Executive Vice President
and Chief Financial Officer of SEACOR, is a member of the Management Committee
of the Company.
 
    In addition to the management fee to be paid as described above with respect
to the services of Mr. Fagerstal, in the event SEACOR or any of its consolidated
subsidiaries, including SEACOR Rigs, provides management, administrative,
financial or investment banking-type services to the Company or services in
connection with any future rig transactions, such SEACOR entities shall be
entitled to receive reasonable fees and reimbursement of expenses not in excess
of fees charged by unrelated third parties for comparable services.
 
SERVICES AGREEMENT
 
    The Company and SEACOR have entered into a Management and Administrative
Services Agreement, dated as of February 27, 1998 (the "Services Agreement"),
pursuant to which SEACOR agreed to continue to provide the services of Dick H.
Fagerstal to assist in the management of the Company and SEACOR agreed to
perform certain administrative and technical services on behalf of the Company.
Such services include general management and financial services, including
periodic advice and consultation in connection with corporate, legal, finance,
accounting, tax, marketing, operations and other matters that may be required
for the Company's day-to-day operations. Under the Services Agreement, the
Company agreed to pay a fee to SEACOR for Mr. Fagerstal's services not to exceed
$15,000 per month and such other fees for services of others not to exceed the
reasonable value thereof and to reimburse SEACOR for all out-of-pocket expenses
related to the provision of such services. The Services Agreement may be
terminated at either party's option upon 60 days' notice to the other party. In
addition, the Company has agreed to indemnify and hold harmless SEACOR for all
claims and damages arising from the provision of services by SEACOR under the
Services Agreement, unless due to the gross negligence or willful misconduct of
SEACOR.
 
OPERATING AGREEMENT
 
    SEACOR Rigs, COI and the investors pursuant to the Equity Financing
(together with SEACOR Rigs and COI, herein referred to collectively as the
"Members" and individually as a "Member") have entered into an Amended and
Restated Operating Agreement, dated as of December 16, 1997 (as amended by
Amendment No. 1 thereto, dated effective as of April 28, 1998, the "Operating
Agreement"), providing for the management of the Company and certain limitations
on the transferability of the membership interests in the Company held by them
(the "Membership Interests"). The following is a description of certain material
terms of the Operating Agreement of the Company, which sets forth matters
related to the conduct of the Company's business and the purpose and powers of
the Company, its Management Committee and officers and the rights, privileges
and preferences of its Members.
 
    ORGANIZATION AND DURATION.  The Company was organized as a limited liability
company under the Delaware Limited Liability Company Act (the "Delaware Act") on
August 5, 1997. The term of the Company will continue until the close of
business on August 1, 2032 or until an earlier dissolution pursuant to the
Operating Agreement. The existence of the Company as a separate legal entity
will continue until cancellation of the Certificate of Formation of the Company
in the manner required by the Delaware Act.
 
    PURPOSE.  The purposes of the Company, and the nature of the business to be
conducted and promoted by the Company, are (a) to manage and supervise either
directly or through one or more other entities owned and controlled directly or
indirectly by the Company, all aspects of the construction of premium jackup
rigs, and, upon their completion, manage all aspects of their operation and
receive
 
                                       45
<PAGE>
therefor certain construction supervision fees and management fees, (b) to form
and act as managing general partner of any such entity that is a partnership,
(c) to engage in any other lawful act or activity for which limited liability
companies may be formed under the Delaware Act and (d) to engage in any and all
activities necessary, advisable, convenient or incidental to the foregoing.
 
    RESTRICTIONS ON TRANSFERABILITY.  Generally, the Members may not sell,
transfer, hypothecate or pledge any of their Membership Interests.
Notwithstanding the foregoing, a Member that is a natural person may freely
transfer its Membership Interest to certain immediate family members and a
Member that is not a natural person may freely transfer its Membership Interests
to certain affiliates. Members may also transfer Membership Interests pursuant
to the Right of First Offer, Tag-Along Rights and Drag-Along Rights described
below.
 
    RIGHT OF FIRST OFFER.  In the event a Member proposes to transfer its
Membership Interest to a proposed purchaser, in whole or part, each other Member
will have the option to purchase a portion of such Membership Interest on a pro
rata basis at the same price and on the same terms as such proposed purchaser
(provided that the current Members, taken as a whole, purchase the entire
interest offered for sale).
 
    TAG-ALONG RIGHTS.  Generally, no Member or group of Members may sell, in one
transaction or a series of related transactions, 20% or more of all the
Membership Interests, unless the terms of such sale require that the proposed
purchaser offer to each other Member the right to participate in the sale on a
pro rata basis.
 
    DRAG-ALONG RIGHTS.  Generally, any Member or group of Members selling all of
their holdings aggregating more than a majority of all the Membership Interests
may require all of the other Members to sell all their Membership Interests to
the proposed purchaser on the same terms and conditions.
 
    PRE-EMPTIVE RIGHTS.  Generally, each Member will have a right to purchase
all or a portion of its pro rata share of additional Membership Interests to be
sold by the Company. Members have no pre-emptive rights with respect to
Membership Interests granted pursuant to the Option Plan.
 
    "PIGGYBACK" REGISTRATION RIGHTS.  Generally, if the Company seeks to
register any class of its equity securities in a primary public offering under
the Securities Act pursuant to an effective registration statement, each Member
will have the right to "piggy back" or sell its Membership Interest, or shares
received in exchange therefor, as part of the registered offering.
 
    GOVERNANCE.  The Company will be managed by a Management Committee comprised
of up to seven Managers. SEACOR Rigs (together with its permitted successors or
assigns, the "Group A Members") shall designate up to four Managers and COI
(together with its permitted successors or assigns, the "Group B Members") shall
designate up to two Managers, of which one will be William E. Chiles so long as
he is President and Chief Executive Officer of the Company. In addition, the new
investors pursuant to the Equity Financing (together with their respective
permitted successors or assigns, the "Group C Members"), by vote of the holders
of a majority of Membership Interests held by such investors, will have the
right to designate one Manager. The Managers initially designated by SEACOR Rigs
were Charles Fabrikant, Randall Blank, Timothy J. McKeand and Dick H. Fagerstal.
The Managers initially designated by COI were William E. Chiles and Jonathan B.
Fairbanks. The initial designee of the new investors was Robert Pierot, Jr. The
Management Committee acts by majority vote. A quorum for taking action at any
meeting of the Management Committee requires the presence of at least four
Managers. Charles Fabrikant, Chairman and CEO of SEACOR, serves as the Chairman
of the Management Committee of the Company.
 
    OFFICERS.  The Management Committee has the authority to appoint the
officers of the Company. The Management Committee may appoint such officers as
it deems appropriate, which may include a President and Chief Executive Officer,
Senior Vice President, Vice President, Chief Operating Officer, Chief Financial
Officer, Treasurer, Controller or Secretary.
 
                                       46
<PAGE>
    MEMBERSHIP INTEREST OPTION PLAN.  The Company may issue up to five (5%)
percent, on a fully-diluted basis, of additional Membership Interests in the
Company in the form of options to employees, directors, advisors or consultants
to the Company or its subsidiaries, without triggering pre-emptive rights under
the Operating Agreement, so long as such options are exercisable at a price that
is not less than the price per percentage Membership Interest paid in the Equity
Financing. The Option Committee will control the granting and vesting terms of
any such options. See "Management--Membership Interest Option Plan" and
"--Option Repurchase Obligation."
 
    LIMITED LIABILITY.  Generally, the debts, obligations and liabilities of a
Delaware limited liability company, whether arising in contract, tort or
otherwise, are solely the debts, obligations and liabilities of the limited
liability company, and no owner of an equity interest therein is obligated
personally for any such debt, obligation or liability of the limited liability
company solely by reason of being an owner thereof.
 
    INDEMNIFICATION.  The Operating Agreement provides that the Company will
indemnify the Members, members of the Management Committee and the officers of
the Company, and certain other persons, from liabilities arising in the course
of such persons' service to the Company, provided that (i) the indemnitee acted
in good faith and in a manner which such indemnitee believed to be in or not
opposed to the interests of the Company and, with respect to any criminal
proceeding, had no reasonable cause to believe such indemnitee's conduct was
unlawful and (ii) the indemnitee's conduct did not constitute actual fraud,
gross negligence or willful or wanton misconduct. Such liabilities include all
losses, claims, demands, costs, damages, liabilities, expenses of any nature
(including reasonable attorneys' fees and disbursements), judgments, fines,
settlements and other amounts arising from any and all claims, demands, actions,
suits or proceedings, whether civil, criminal, administrative or investigative,
in which an indemnitee may be involved, or threatened to be involved, as a party
or otherwise, arising out of or incidental to the business of the Company,
including, without limitation, liabilities under the Federal and state
securities laws.
 
BROKERAGE FEE
 
    Bassoe will be paid a brokerage fee of $505,000 upon delivery of each Rig
presently under construction at AMFELS. Such brokerage fees and commissions will
be included in the cost of the Rigs paid to AMFELS. Bassoe also has an exclusive
right to broker future sale, purchase and charter transactions with respect to
the Rigs, provided that its rates are not in excess of rates charged by
unrelated third parties in similar transactions.
 
OPTION REPURCHASE OBLIGATION
 
    Pursuant to the Option Plan, the Company has agreed to repurchase any
options granted under the Option Plan that have vested and are exercisable at
their expiration if there has been no initial public offering of the Company's
Membership Interests prior to such time. The value attributed to such options
under such repurchase shall be determined by reference to the last sale price of
the Membership Interests on such date on a national securities exchange or
inter-dealer quotation system, or, if no such Membership Interests are so listed
or traded, then by reference to the fair market value of such Membership
Interests. The determination of fair market value by the Option Committee shall
be conclusive. For a description of other terms of the Option Plan, see
"Management--Membership Interest Option Plan."
 
GUARANTEE OF OFFICE LEASE
 
    On October 1, 1997, SEACOR Marine, Inc. ("SEACOR Marine"), a subsidiary of
SEACOR, agreed to guarantee the Company's lease (the "Lease Guarantee") of its
principal office space. The Lease Guarantee obligates SEACOR Marine as if it
were the lessee of the office space, but it also allows the Company and the
lessor to modify, extend or amend such lease without notice to SEACOR Marine.

                          DESCRIPTION OF BANK FACILITY
 
    The following description of certain material provisions of certain
indebtedness of the Company does not purport to be complete, and is subject to,
and is qualified in its entirety by reference to, the forms of such instruments,
copies of which may be obtained as described under "Available Information."
 
    The Company entered into the Bank Facility, which was arranged by
Nederlandse Scheepshypotheek Bank N.V. and MeesPierson Capital Corp., effective
as of the closing date of the Original Offering. The Bank Facility provides for
a $25.0 million revolving credit facility maturing December 31, 2004. Borrowings
under the Bank Facility may be repaid and reborrowed during the term thereof and
will bear interest at a per annum rate equal to LIBOR plus a margin of 1.25%.
Subject to satisfaction of customary conditions precedent, including that there
shall have occurred no material adverse change with respect to the Company or
its business, assets, properties or prospects since the date of execution of the
Bank Facility, availability under the Bank Facility will commence upon the first
delivery of a Rig. Until the commencement of availability, the Company will be
required to pay quarterly in arrears a commitment fee equal to 0.25% per annum
on the undrawn amount of the facility, thereafter increased to 0.50% per annum.
 
    The Bank Facility is guaranteed by the Owners and such guarantees are
secured by first priority mortgages on the Rigs, assignments of earnings of the
Rigs (which may continue to be collected by the Company unless there occurs an
event of default) and assignments of insurance proceeds.
 
    The Bank Facility contains customary affirmative covenants, representations
and warranties and is cross-defaulted to the Notes; PROVIDED, HOWEVER, should
there occur an event of default under the Bank Facility (other than arising from
enforcement actions undertaken by a holder of other indebtedness of the Company,
enforcement actions arising from IN REM claims against either of the Rigs or
bankruptcy events with respect to the Company or an Owner), the lenders under
the Bank Facility have agreed on a one-time basis not to enforce remedies for a
period of 60 days during which the Noteholders or the Company may cure such
event of default or prepay all of the indebtedness outstanding under the
facility. In addition, the Bank Facility requires that the fair market value of
the Rigs, as determined by appraisers appointed by the lenders thereunder, at
all times equals or exceeds an amount equal to 130% of outstanding indebtedness
under the facility.

                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT
 
    The Old Notes were sold by the Issuers on April 29, 1998, in a private
placement. In connection with that placement, the Issuers entered into the
Registration Rights Agreement, which requires that the Issuers file a
registration statement under the Securities Act with respect to the New Notes
and, upon the effectiveness of that registration statement, offer to the Holders
of the Old Notes the opportunity to exchange their Old Notes for a like
principal amount of New Notes, which will be issued without a restrictive legend
and may be reoffered and resold by the Holder without registration under the
Securities Act. The Registration Rights Agreement further provides that the
Company must use its reasonable best efforts to cause the Registration Statement
with respect to the Exchange Offer to be declared effective on or before August
27, 1998 and the Exchange Offer consummated on or before            , 1998.
Except as provided below, upon the completion of the Exchange Offer, the
Company's obligations with respect to the registration of the Old Notes and the
New Notes will terminate. A copy of the Registration Rights Agreement has been
filed as an exhibit to the Registration Statement of which this Prospectus is a
part and although the Issuers believe that the summary herein of certain
provisions thereof describes all material elements of the Registration Rights
Agreement, such summary does not purport to be complete and is subject thereto,
and is qualified in its entirety by reference thereto. As a result of the filing
and the effectiveness of the Registration Statement, certain additional interest
provided for in the Registration Rights Agreement will not become payable by the
Company. Following the completion of the Exchange Offer (except as set forth in
the paragraph immediately below), holders of Old Notes not tendered will not
have any further registration rights and those Old Notes will continue to be
subject to certain restrictions on transfer. Accordingly, any liquidity of the
market for the Old Notes could be adversely affected upon completion of the
Exchange Offer.
 
    In order to participate in the Exchange Offer, a holder must represent to
the Issuers, among other things, that (i) the New Notes acquired pursuant to the
Exchange Offer are being obtained in the ordinary course of business of the
person receiving the New Notes, whether or not such person is the Holder of the
Old Notes, (ii) neither the Holder nor any such other person is engaging in or
intends to engage in a distribution of the New Notes, (iii) neither the Holder
nor any such other person has an arrangement or understanding with any person to
participate in the distribution of the New Notes and (iv) neither the Holder nor
any such other person is an "affiliate," as defined under Rule 405 promulgated
under the Securities Act, of either of the Issuers or either of the Guarantors.
In the event that (i) because of any change of law or in applicable
interpretations of the staff of the Commission, the Issuers are not permitted to
effect the Exchange Offer, or (ii) if for any other reason the Exchange Offer is
not consummated within 150 days of the date of the Original Offering, or (iii)
if any Initial Purchaser in the Original Offering so requests with respect to
Old Notes not eligible to be exchanged for New Notes in the Exchange Offer and
held by it following consummation of the Exchange Offer, or (iv) if any Holder
of Old Notes (other than a broker-dealer that receives New Notes for its own
account in exchange for Old Notes, where such Old Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities (a "Participating Broker-Dealer") is not eligible to participate in
the Exchange Offer or any such Holder (other than a Participating Broker-Dealer)
does not receive freely tradeable New Notes in the Exchange Offer, the Issuers
are required, pursuant to the Registration Rights Agreement, to file a "shelf"
registration statement for a continuous offering pursuant to Rule 415 under the
Securities Act in respect of the Old Notes (and use their reasonable best
efforts to cause such shelf registration statement to be declared effective by
the Commission and keep it continuously effective, supplemented and amended for
prescribed periods). See "--Procedures for Tenders."
 
    Based on an interpretation by the Commission's staff set forth in no-action
letters issued to third parties unrelated to the Issuers, the Issuers believe
that, with the exceptions set forth below, New Notes issued pursuant to the
Exchange Offer in exchange for Old Notes may be offered for resale, resold and
otherwise transferred by any person receiving such New Notes, whether or not
such person is the Holder (other than any such holder or such other person that
is an "affiliate" of either of the Issuers or either of
 
                                       49
<PAGE>
the Guarantors within the meaning of Rule 405 under the Securities Act) without
compliance with the registration and prospectus delivery provisions of the
Securities Act, provided that the New Notes are
acquired in the ordinary course of business of the Holder or such other person
and neither the Holder nor such other person has an arrangement or understanding
with any person to participate in the distribution of such New Notes. Any Holder
who tenders in the Exchange Offer for the purpose of participating in a
distribution of the New Notes cannot rely on this interpretation by the
Commission's staff and must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction. Each Participating Broker-Dealer must acknowledge that it will
deliver a prospectus in connection with any resale of such New Notes. See "Plan
of Distribution."
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
    Following the completion of the Exchange Offer, (except as set forth in the
second paragraph under "--Purpose and Effect" above), holders of Old Notes not
tendered will not have any further registration rights and those Old Notes will
continue to be subject to certain restrictions on transfer. Accordingly, any
liquidity of the market for a holder's Old Notes could be adversely affected
upon completion of the Exchange Offer if the holder does not participate in the
Exchange Offer.
 
TERMS OF THE EXCHANGE OFFER
 
    Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Old Notes
validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on
the Expiration Date. The Company will issue $1,000 principal amount of New Notes
in exchange for each $1,000 principal amount of outstanding Old Notes accepted
in the Exchange Offer. Holders may tender some or all of their Old Notes
pursuant to the Exchange Offer. However, Old Notes may be tendered only in
integral multiples of $1,000 in principal amount.
 
    The form and terms of the New Notes are substantially the same as the form
and terms of the Old Notes except that the New Notes will have been registered
under the Securities Act and will not bear legends restricting their transfer.
The New Notes will evidence the same debt as the Old Notes and will be issued
pursuant to, and entitled to the benefits of, the Indenture pursuant to which
the Old Notes were issued. Interest on the New Notes shall accrue from the date
of issuance of the Old Notes
 
    As of May 31, 1998, Old Notes representing $110,000,000 aggregate principal
amount were outstanding. This Prospectus, together with the Letter of
Transmittal, is being sent to each registered Holder and to others believed to
have beneficial interests in the Old Notes. Holders of Old Notes do not have any
appraisal or dissenters' rights under the General Corporation Law of the State
of Delaware or the Indenture in connection with the Exchange Offer. The Company
intends to conduct the Exchange Offer in accordance with the applicable
requirements of the Exchange Act and the rules and regulations of the Commission
promulgated thereunder.
 
    The Company shall be deemed to have accepted validly tendered Old Notes
when, as, and if the Company has given oral or written notice thereof to U.S.
Bank Trust National Association, the Exchange Agent. The Exchange Agent will act
as agent for the tendering Holders for the purpose of receiving the New Notes
from the Company. If any tendered Old Notes are not accepted for exchange
because of an invalid tender, the occurrence of certain other events set forth
herein or otherwise, certificates for any such unaccepted Old Notes will be
returned, without expense, to the tendering Holder thereof as promptly as
practicable after the Expiration Date.
 
    Holders who tender Old Notes in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the Letter
of Transmittal, transfer taxes with respect to the exchange of Old Notes
pursuant to the Exchange Offer. The Company will pay all charges and expenses,
other than certain applicable taxes, in connection with the Exchange Offer. See
"The Exchange Offer--Fees and Expenses."
 
                                       50
<PAGE>
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
    The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
September   , 1998, unless the Company, in its sole discretion, extends the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date and time to which the Exchange Offer is extended. In order to extend the
Exchange Offer, the Company will notify the Exchange Agent and each registered
Holder of any extension by oral or written notice prior to 9:00 a.m., New York
City time, on the next business day after the previously scheduled Expiration
Date. The Company reserves the right, in its sole discretion, (i) to delay
accepting any Old Notes, to extend the Exchange Offer or, if any of the
conditions set forth under "The Exchange Offer--Conditions to Exchange Offer"
shall not have been satisfied, to terminate the Exchange Offer, by giving oral
or written notice of such delay, extension or termination to the Exchange Agent,
or (ii) to amend the terms of the Exchange Offer in any manner.
 
PROCEDURES FOR TENDERS
 
    Only a Holder of Old Notes may tender the Old Notes in the Exchange Offer.
Except as set forth under "The Exchange Offer--Book Entry Transfer," to tender
in the Exchange Offer a Holder must complete, sign and date the Letter of
Transmittal, or a copy thereof, have the signatures thereon guaranteed if
required by the Letter of Transmittal, and mail or otherwise deliver the Letter
of Transmittal or a copy thereof to the Exchange Agent prior to the Expiration
Date. In addition, either (i) certificates for such Old Notes must be received
by the Exchange Agent along with the Letter of Transmittal, or (ii) a timely
confirmation of a book-entry transfer (a "Book-Entry Confirmation") of such Old
Notes, if that procedure is available, into the Exchange Agent's account at DTC
(the "Book-Entry Transfer Facility") pursuant to the procedure for book-entry
transfer described below, must be received by the Exchange Agent prior to the
Expiration Date, or (iii) the Holder must comply with the guaranteed delivery
procedures described below. To be tendered effectively, the Letter of
Transmittal and other required documents must be received by the Exchange Agent
at the address set forth under "The Exchange Offer-- Exchange Agent" prior to
the Expiration Date.
 
    The tender by a Holder that is not withdrawn before the Expiration Date will
constitute an agreement between that Holder and the Company in accordance with
the terms and subject to the conditions set forth herein and in the Letter of
Transmittal.
 
    THE METHOD OF DELIVERY OF OLD NOTES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE
HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN
OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO
LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO THE COMPANY. HOLDERS MAY
REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR
NOMINEES TO EFFECT THESE TRANSACTIONS FOR SUCH HOLDERS.
 
    Any beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to tender
should contact the registered Holder promptly and instruct the registered Holder
to tender on the beneficial owner's behalf. If the beneficial owner wishes to
tender on the owner's own behalf, the owner must, prior to completing and
executing the Letter of Transmittal and delivering the owner's Old Notes, either
make appropriate arrangements to register ownership of the Old Notes in the
beneficial owner's name or obtain a properly completed bond power from the
registered Holder. The transfer of registered ownership may take considerable
time.
 
    Signatures on a Letter of Transmittal or a notice of withdrawal, as the case
may be, must be guaranteed by an Eligible Institution (as defined) unless Old
Notes tendered pursuant thereto are tendered (i) by a registered Holder who has
not completed the box entitled "Special Delivery Instructions" on the Letter of
Transmittal or (ii) for the account of an Eligible Institution. If signatures on
a Letter of Transmittal or a notice of withdrawal, as the case may be, are
required to be guaranteed, the guarantee
 
                                       51
<PAGE>
must be made by any eligible guarantor institution that is a member of or
participant in the Securities Transfer Agents Medallion Program, the New York
Stock Exchange Medallion Signature Program, the Stock Exchange Medallion
Program, or an "eligible guarantor institution" within the meaning of Rule
17Ad-15 under the Exchange Act (an "Eligible Institution").
 
    If the Letter of Transmittal is signed by a person other than the registered
Holder of any Old Notes listed therein, the Old Notes must be endorsed or
accompanied by a properly completed bond power, signed by the registered Holder
as that registered Holder's name appears on the Old Notes.
 
    If the Letter of Transmittal or any Old Notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations, or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and evidence satisfactory to the
Company of their authority to so act must be submitted with the Letter of
Transmittal unless waived by the Company.
 
    All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Old Notes will be determined by
the Company in its sole discretion, which determination will be final and
binding. The Company reserves the absolute right to reject any and all Old Notes
not properly tendered or any Old Notes the Company's acceptance of which would,
in the opinion of counsel for the Company, be unlawful. The Company also
reserves the right to waive any defects, irregularities or conditions of tender
as to particular Old Notes. The Company's interpretation of the terms and
conditions of the Exchange Offer (including the instructions in the Letter of
Transmittal) will be final and binding on all parties. Unless waived, any
defects or irregularities in connection with tenders of Old Notes must be cured
within such time as the Company shall determine. Although the Company intends to
notify Holders of defects or irregularities with respect to tenders of Old
Notes, neither the Company, the Exchange Agent, nor any other person shall incur
any liability for failure to give such notification. Tenders of Old Notes will
not be deemed to have been made until such defects or irregularities have been
cured or waived. Any Old Notes received by the Exchange Agent that are not
properly tendered or as to which the defects or irregularities have not been
cured or waived will be returned by the Exchange Agent to the tendering Holders,
unless otherwise provided in the Letter of Transmittal, as soon as practicable
following the Expiration Date.
 
    In addition, the Company reserves the right in its sole discretion to
purchase or make offers for any Old Notes that remain outstanding after the
Expiration Date or, as set forth under "The Exchange Offer-- Conditions to the
Exchange Offer," to terminate the Exchange Offer and, to the extent permitted by
applicable law, purchase Old Notes in the open market, in privately negotiated
transactions, or otherwise. The terms of any such purchases or offers could
differ from the terms of the Exchange Offer.
 
    By tendering, each Holder will represent to the Company that, among other
things, (i) the New Notes acquired pursuant to the Exchange Offer are being
obtained in the ordinary course of business of the person receiving such New
Notes, whether or not such person is the Holder, (ii) neither the Holder nor any
such other person is engaging in or intends to engage in a distribution of such
New Notes, (iii) neither the Holder nor any such other person has an arrangement
or understanding with any person to participate in the distribution of such New
Notes and (iv) neither the Holder nor any such other person is an "affiliate" as
defined under Rule 405 of the Securities Act, of the Company, Finance or either
Guarantor.
 
    In the event that (i) because of any change of law or in applicable
interpretations of the staff of the Commission, the Issuers are not permitted to
effect the Exchange Offer, or (ii) if for any other reason the Exchange Offer is
not consummated within 150 days of the date of the Original Offering, or (iii)
if any Initial Purchaser in the Original Offering so requests with respect to
Old Notes not eligible to be exchanged for New Notes in the Exchange Offer and
held by it following consummation of the Exchange Offer, or (iv) if any Holder
of Old Notes (other than a Participting Broker-Dealer) is not eligible to
participate in the Exchange Offer or any such Holder (other than a Participating
Broker-Dealer) does not receive freely tradeable New Notes in the Exchange
Offer, the Issuers are required, pursuant to the Registration Rights Agreement,
to file a "shelf" registration statement for a continuous offering pursuant
 
                                       52
<PAGE>
to Rule 415 under the Securities Act in respect of the Old Notes (and use their
reasonable best efforts to cause such shelf registration statement to be
declared effective by the Commission and keep it continuously effective,
supplemented and amended for prescribed periods).
 
    In all cases, issuance of New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of certificates for such Old Notes or a timely Book-Entry
Confirmation of such Old Notes into the Exchange Agent's account at the
Book-Entry Transfer Facility, a properly completed and duly executed Letter of
Transmittal (or, with respect to the DTC and its participants, electronic
instructions in which the tendering Holder acknowledges its receipt of and
agreement to be bound by the Letter of Transmittal) and all other required
documents. If any tendered Old Notes are not accepted for any reason set forth
in the terms and conditions of the Exchange Offer or if Old Notes are submitted
for a greater principal amount than the Holder desires to exchange, such
unaccepted or non-exchanged Old Notes will be returned without expense to the
tendering Holder thereof (or, in the case of Old Notes tendered by book-entry
transfer into the Exchange Agent's account at the Book-Entry Transfer Facility
pursuant to the book-entry transfer procedures described below, such
non-exchanged Old Notes will be credited to an account maintained with such
Book-Entry Transfer Facility) as promptly as practicable after the expiration or
termination of the Exchange Offer.
 
    Each broker-dealer that receives New Notes for its own account in exchange
for Old Notes, where such Old Notes were acquired by such broker-dealer as a
result of market-making activities or other trading activities, must acknowledge
that it will deliver a prospectus in connection with any resale of such New
Notes. See "Plan of Distribution."
 
BOOK-ENTRY TRANSFER
 
    The Exchange Agent will make a request to establish an account with respect
to the Old Notes at the Book-Entry Transfer Facility for purposes of the
Exchange Offer within two business days after the date of this Prospectus, and
any financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of Old Notes being tendered by
causing the Book-Entry Transfer Facility to transfer such Old Notes into the
Exchange Agent's account at the Book-Entry Transfer Facility in accordance with
such Book-Entry Transfer Facility's procedures for transfer. However, although
delivery of Old Notes may be effected through book-entry transfer at the
Book-Entry Transfer Facility, the Letter of Transmittal or a copy thereof, with
any required signature guarantees and any other required documents, must, in any
case other than as set forth in the following paragraph, be transmitted to and
received by the Exchange Agent at the address set forth under "The Exchange
Offer--Exchange Agent" on or prior to the Expiration Date or the guaranteed
delivery procedures described below must be complied with.
 
    DTC's Automated Tender Offer Program ("ATOP") is the only method of
processing exchange offers through DTC. To accept the Exchange Offer through
ATOP, participants in DTC must send electronic instructions to DTC through DTC's
communication system in place of sending a signed, hard copy Letter of
Transmittal. DTC is obligated to communicate those electronic instructions to
the Exchange Agent. To tender Old Notes through ATOP, the electronic
instructions sent to DTC and transmitted by DTC to the Exchange Agent must
contain the character by which the participant acknowledges its receipt of and
agrees to be bound by the Letter of Transmittal.
 
GUARANTEED DELIVERY PROCEDURES
 
    If a registered Holder of the Old Notes desires to tender such Old Notes and
the Old Notes are not immediately available, or time will not permit such
Holder's Old Notes or other required documents to reach the Exchange Agent
before the Expiration Date, or the procedure for book-entry transfer cannot be
completed on a timely basis, a tender may be effected if (i) the tender is made
through an Eligible Institution, (ii) prior to the Expiration Date, the Exchange
Agent received from such Eligible Institution a properly completed and duly
executed Letter of Transmittal (or a copy thereof) and Notice of Guaranteed
Delivery, substantially in the form provided by the Company (by telegram, telex,
facsimile transmission,
 
                                       53
<PAGE>
mail or hand delivery), setting forth the name and address of the holder of Old
Notes and the amount of Old Notes tendered, stating that the tender is being
made thereby and guaranteeing that within three New York Stock Exchange ("NYSE")
trading days after the date of execution of the Notice of Guaranteed Delivery,
the certificates for all physically tendered Old Notes, in proper form for
transfer, or a Book-Entry Confirmation, as the case may be, and any other
documents required by the Letter of Transmittal will be deposited by the
Eligible Institution with the Exchange Agent, and (iii) the certificates for all
physically tendered Old Notes, in proper form for transfer, or a Book-Entry
Confirmation, as the case may be, and all other documents required by the Letter
of Transmittal, are received by the Exchange Agent within three NYSE trading
days after the date of execution of the Notice of Guaranteed Delivery.
 
WITHDRAWAL RIGHTS
 
    Tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New
York City time, on the Expiration Date.
 
    For a withdrawal of a tender of Old Notes to be effective, a written or (for
DTC participants) electronic ATOP transmission notice of withdrawal must be
received by the Exchange Agent at its address set forth in this Prospectus prior
to 5:00 p.m., New York City time, on the Expiration Date. Any such notice of
withdrawal must (i) specify the name of the person having deposited the Old
Notes to be withdrawn (the "Depositor"), (ii) identify the Old Notes to be
withdrawn (including the certificate number or numbers and principal amount of
such Old Notes), (iii) be signed by the Holder in the same manner as the
original signature on the Letter of Transmittal by which such Old Notes were
tendered (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Trustee register the transfer of
such Old Notes into the name of the person withdrawing the tender, and (iv)
specify the name in which any such Old Notes are to be registered, if different
from that of the Depositor. All questions as to the validity, form, and
eligibility (including time of receipt) of such notices will be determined by
the Company, whose determination shall be final and binding on all parties. Any
Old Notes so withdrawn will be deemed not to have been validly tendered for
exchange for purposes of the Exchange Offer. Any Old Notes which have been
tendered for exchange but which are not exchanged for any reason will be
returned to the Holder thereof without cost to such Holder as soon as
practicable after withdrawal, rejection of tender, or termination of the
Exchange Offer. Properly withdrawn Old Notes may be retendered by following one
of the procedures under "The Exchange Offer--Procedures for Tendering" at any
time on or prior to the Expiration Date.
 
CONDITIONS TO THE EXCHANGE OFFER
 
    Notwithstanding any other provision of the Exchange Offer, the Company shall
not be required to accept for exchange, or to issue New Notes in exchange for,
any Old Notes and may terminate or amend the Exchange Offer if at any time
before the acceptance of such Old Notes for exchange or the exchange of the New
Notes for such Old Notes, the Company determines that the Exchange Offer
violates applicable law, any applicable interpretation of the staff of the
Commission or any order of any governmental agency or court of competent
jurisdiction.
 
    The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company regardless of the circumstances giving rise to any such
condition or may be waived by the Company in whole or in part at any time and
from time to time in its reasonable discretion. The failure by the Company at
any time to exercise any of the foregoing rights shall not be deemed a waiver of
any such right and each such right shall be deemed an ongoing right which may be
asserted at any time and from time to time.
 
    In addition, the Company will not accept for exchange any Old Notes
tendered, and no New Notes will be issued in exchange for any such Old Notes, if
at such time any stop order shall be threatened or in effect with respect to the
Registration Statement of which this Prospectus constitutes a part or the
qualification of the Indenture under the Trust Indenture Act of 1939, as amended
(the "Trust Indenture
 
                                       54
<PAGE>
Act"). In any such event the Company is required to use every reasonable
commercial effort to obtain the withdrawal of any stop order at the earliest
possible time.

                            DESCRIPTION OF NEW NOTES
 
GENERAL
 
    The Notes will be issued under the Indenture, dated as of April 29, 1998
(the "Indenture"), among the Company, Finance, the Subsidiary Guarantors and
U.S. Bank Trust National Association, as Trustee (the "Trustee"). Upon the
issuance of the New Notes, the Indenture will be subject to and governed by the
Trust Indenture Act. The New Notes are subject to all such terms, and Holders of
New Notes are referred to the Indenture and the Trust Indenture Act for a
statement thereof. The following summary of certain provisions of the Indenture
and the New Notes does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, all the provisions of the Indenture
and the Notes, including the definitions of certain terms therein and those
terms made a part thereof by the Trust Indenture Act. As used in this
"Description of New Notes" section, references to the "Company" include only
Chiles Offshore LLC and not its Subsidiaries.
 
    Principal of, premium, if any, and interest on the New Notes will be
payable, and the New Notes may be exchanged or transferred, at the office or
agency of the Issuers in the Borough of Manhattan, The City of New York, which
initially shall be the corporate trust office of the Trustee's agent, at 100
Wall Street, New York, New York 10041, except that, at the option of the
Issuers, payment of interest may be made by check mailed to the address of the
Holders as such address appears in the Note register; PROVIDED that all payments
with respect to Global Notes and certificated Notes the Holders of which have
given wire transfer instructions to the Company and its paying agent prior to
the applicable record date for such payment will be required to be made by wire
transfer of immediately available funds to the accounts specified by the Holders
thereof.
 
    The New Notes will be issued only in fully registered form, without coupons,
in denominations of $1,000 and any integral multiple of $1,000. See "--Book
Entry, Delivery and Form." No service charge shall be made for any registration
or exchange of the Notes, but the Company may require payment of a sum
sufficient to cover any transfer tax or other similar governmental charge
payable in connection therewith.
 
TERMS OF THE NOTES
 
    The New Notes will be joint and several senior obligations of the Issuers,
and will be unsecured except with respect to the Escrowed Property. See
"--Escrow of Proceeds." The Indenture provides for the issuance of the $110.0
million principal amount of Old Notes pursuant to the Original Offering and, in
exchange therefor, a like principal amount of New Notes being offered hereby and
additional Notes, subject to compliance with the covenant described below under
the caption "--Certain Covenants-- Limitation on Indebtedness"; PROVIDED,
HOWEVER, that no Default or Event of Default exists under the Indenture at the
time of issuance or would result therefrom and that the aggregate principal
amount of Notes issued under the Indenture does not exceed $250.0 million. All
New Notes will be substantially identical in all material respects other than
issuance dates. The Notes will mature on May 1, 2008. The Notes will bear
interest at the rate per annum shown on the cover page hereof from April 29,
1998, or from the most recent date to which interest has been paid or provided
for, payable semiannually to Holders of record at the close of business on the
April 15 or October 15 immediately preceding the interest payment date on May 1
and November 1 of each year, commencing November 1, 1998. The Issuers will pay
interest on overdue principal at 1.0% per annum in excess of such rate and, to
the extent permitted by applicable law, on overdue installments of interest at
such higher rate. Interest on the Notes will be computed on the basis of a
360-day year of twelve 30-day months.

ESCROW OF PROCEEDS
 
    Concurrently with the closing of the Original Offering, the Company entered
into an escrow agreement (the "Escrow Agreement") with U.S. Bank Trust National
Association, as Escrow Agent, pursuant to which the Company initially deposited
with the Escrow Agent an aggregate amount equal to the net cash proceeds of the
Original Offering, together with approximately $0.2 million for additional Notes
issuance costs, as follows: (i) into the Interest Escrow Account, approximately
$11.1 million in cash, being the amount as will be sufficient to provide for
payment in full of the first two scheduled interest payments on the Notes and
(ii) into the Construction Escrow Account, approximately $95.4 million in cash,
representing the balance. The Interest Escrow Account and the Construction
Escrow Account are sometimes referred to herein together as the "Escrow
Accounts," and the cash and Temporary Cash Investments deposited therein,
together with the interest, dividends and distributions thereon are sometimes
referred to herein as the "Escrowed Property." Pursuant to a related escrow
security agreement (the "Escrow Security Agreement") with U.S. Bank Trust
National Association, as Collateral Agent, the Company granted a security
interest in the Escrow Accounts and all funds and investments contained therein,
the Escrow Agreement and all proceeds of the foregoing to the Collateral Agent
for the benefit of the Holders pursuant to the Indenture.
 
    The Escrow Agent will make payments from the Interest Escrow Account as
follows: (i) on each of the first two Interest Payment Dates, an amount equal to
the installment then due, to be remitted to the Paying Agent for the Notes, and
(ii) in the event the Company is required to repurchase Notes pursuant to the
Indenture, on the repurchase date, an amount equal to the aggregate amount of
accrued interest paid to the Holders whose Notes were repurchased. A failure to
pay interest on the Notes in a timely manner through the first two scheduled
Interest Payment Dates will constitute an immediate Event of Default under the
Indenture, with no grace or cure period. The Escrowed Property in the Interest
Escrow Account also will secure the repayment of the principal amount of, and
premium, if any, on, the Notes.
 
    The Escrow Agent will make payments from the Construction Escrow Account as
follows: On the first Business Day of each calendar month beginning after the
date that the Company shall have paid to the Builder an aggregate of at least
$50.0 million in installment payments to AMFELS of the Purchase Price of the
Rigs and payments for OFE and Construction Overhead (each as defined in the
Escrow Agreement) (or, in the case of the first calendar month in which the
Company shall have so paid such amount, on any Business Day thereafter during
such calendar month), an amount equal to the sum of (i) each installment payment
of the Purchase Price of the Rigs required to be paid on each Rig Purchase
Installment Date in such calendar month pursuant to the Construction Contracts,
as adjusted for any change orders provided pursuant to the Construction
Contracts, (ii) the aggregate amount estimated in good faith by the Company to
be required in such calendar month to pay for the purchase price of OFE and
Construction Overhead, up to an aggregate amount not to exceed $55.0 million and
(iii) with respect to any calendar month beginning on or after the Delivery Date
of the first Rig to be completed (the "First Completed Rig") and prior to the
Delivery Date of the second Rig to be completed, an aggregate amount estimated
by the Company to be required to fund the working capital in such calendar month
for the operation of the First Completed Rig, up to an aggregate amount not to
exceed $10.0 million; PROVIDED, HOWEVER, that at least three Business Days prior
thereto, the Company shall have delivered to the Trustee and the Escrow Agent an
Officers' Certificate setting forth in reasonable detail (i) the amount,
category and purpose of each requested payment, (ii) in the case of any payments
other than installment payments of the Purchase Prices of the Rigs, the amount
available for payment, after giving effect to all previous payments, and (iii) a
reconciliation of payments made from the Construction Escrow Account to actual
expenditures, which reconciliation shall be made on a cumulative basis through
the end of the second calendar month preceding the month in which such Officers'
Certificate is delivered. Notwithstanding the foregoing, in the event the
Company is required to repurchase Notes upon a Contract Termination, the Escrow
Agent will make a payment on the repurchase date, in an amount equal to the
Allocated Portion of the remaining funds in the Construction Escrow Account, to
be deposited with the Paying Agent for application to pay
 
                                       57
<PAGE>
the purchase price of Notes accepted for repurchase. See "--Right to Require
Repurchase Upon Contract Termination." Pending application of the Escrowed
Property so released from the Construction Escrow Account pursuant to the Escrow
Agreement, such Escrowed Property shall be invested in Temporary Cash
Investments.
 
    Upon receipt by the Escrow Agent of an Officers' Certificate of the Company
that the Company has made the first two scheduled interest payments on the
Notes, the Escrowed Property in the Interest Escrow Account shall be released
from the Interest Escrow Account. Upon receipt by the Escrow Agent of an
Officers' Certificate of the Company that the Company has made the final
installment of the Purchase Price for each of the Rigs in accordance with the
related Construction Contracts, the Escrowed Property in the Construction Escrow
Account will be released from the Construction Escrow Account. Upon release of
all the Escrowed Property from the Escrow Accounts, the Notes will be unsecured.
 
REDEMPTION
 
    OPTIONAL REDEMPTION
 
    Except as set forth in the following paragraph, the Notes will not be
redeemable at the option of the Issuers prior to May 1, 2003. Thereafter, the
Notes will be redeemable, at the Issuers' option, in whole or in part, at any
time or from time to time, upon not less than 30 nor more than 60 days' prior
notice mailed by first class mail to each Holder's registered address, at the
following redemption prices (expressed in percentages of principal amount), plus

</TABLE>
 
    In addition, at any time and from time to time prior to May 1, 2001, the
Issuers may redeem in the aggregate up to 35% of the original principal amount
of the Notes with the proceeds of one or more Public Equity Offerings, at a
redemption price (expressed as a percentage of principal amount) of 110% plus
accrued interest to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on the relevant
interest payment date); PROVIDED, HOWEVER, that at least $71.5 million aggregate
principal amount of the Notes must remain outstanding after each such redemption
and, PROVIDED FURTHER, that such redemption shall occur within 90 days following
the closing of such Public Equity Offering.
 
    SELECTION AND NOTICE
 
    In the case of any partial redemption, selection of the Notes for redemption
will be made by the Trustee on a pro rata basis, by lot or by such other method
as the Trustee in its sole discretion shall deem to be fair and appropriate,
although no Note of $1,000 in original principal amount or less shall be
redeemed in part. If any Note is to be redeemed in part only, the notice of
redemption relating to such Note shall state the portion of the principal amount
thereof to be redeemed. A new Note in principal amount equal to the unredeemed
portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note.
 
RIGHT TO REQUIRE REPURCHASE UPON CONTRACT TERMINATION
 
    In the event a Construction Contract is terminated (a "Contract
Termination") prior to the Delivery Date of the related Rig, each Holder shall
have the right to require that the Issuers repurchase the Allocated Principal
Amount of such Holder's Notes at a purchase price equal to 101% of the principal
 
                                       58
<PAGE>
amount thereof, plus accrued and unpaid interest to and including the date of
repurchase (subject to the right of a Holder of record on the relevant record
date to receive interest due on the relevant Interest Payment Date), on a
payment date no later than 90 days after the termination of such Construction
Contract(s).
 
    Within 30 days following any Contract Termination, unless notice of
redemption of the Notes has been given pursuant to the provisions of the
Indenture described under "--Optional Redemption" above, the Company shall mail
a notice to the Trustee and to each Holder stating: (1) that a Contract
Termination has occurred and that such Holder has the right to require the
Issuers to repurchase such Holder's Notes at a purchase price in cash equal to
101% of the principal amount thereof plus accrued and unpaid interest, if any,
to the date of purchase (subject to the right of holders of record on the
relevant record date to receive interest on the relevant Interest Payment Date);
(2) the circumstances and relevant facts regarding such Contract Termination;
(3) the repurchase date (which shall be no earlier than 30 days nor later than
60 days from the date such notice is mailed); and (4) the instructions
determined by the Company, consistent with the covenant described hereunder,
that a Holder must follow in order to have its Notes repurchased.
 
    The Company shall comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations
in connection with the repurchase of Notes pursuant to the covenant described
hereunder. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of the covenant described hereunder,
the Company shall comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations under the covenant
described hereunder by virtue thereof.
 
SUBSIDIARY GUARANTEES
 
    Each of the Company's Restricted Subsidiaries that is organized and existing
under the laws of any State of the United States or the District of Columbia and
that is an obligor or guarantor with respect to the Bank Facility will
irrevocably and unconditionally Guarantee, as a primary obligor and not merely
as a surety, on an unsecured senior basis the performance and punctual payment
when due, whether at Stated Maturity, by acceleration or otherwise, of all
obligations of the Company under the Indenture and the Notes, whether for
payment of principal of or interest on the Notes, expenses, indemnification or
otherwise (all such obligations guaranteed by the Subsidiary Guarantors being
herein called the "Guaranteed Obligations"). The Subsidiary Guarantors will
agree to pay, in addition to the amount stated above, any and all expenses
(including reasonable counsel fees and expenses) incurred by the Trustee or the
Holders in enforcing any rights under the Subsidiary Guarantees. Each Subsidiary
Guarantee will be limited in amount to an amount not to exceed the maximum
amount that can be Guaranteed by the applicable Subsidiary Guarantor without
rendering such Subsidiary Guarantee voidable under applicable law relating to
fraudulent conveyance or fraudulent transfer or similar laws affecting the
rights of creditors generally. After the Issue Date, the Company will cause each
Restricted Subsidiary that is organized and existing under the laws of any State
of the United States or the District of Columbia and that becomes an obligor or
guarantor with respect to any of the obligations under the Bank Facility to
execute and deliver to the Trustee a supplemental indenture pursuant to which
such Restricted Subsidiary will Guarantee on an unsecured senior basis the
payment of the Notes. See "Certain Covenants--Future Subsidiary Guarantors"
below.
 
    Each Subsidiary Guarantee is a continuing guarantee and shall (a) remain in
full force and effect until payment in full of all the Guaranteed Obligations,
(b) be binding upon each Subsidiary Guarantor and (c) inure to the benefit of
and be enforceable by the Trustee, the Holders and the respective successors,
transferees and assigns thereof.
 
    Each Subsidiary Guarantor may consolidate with or merge into or sell its
assets to the Company or another Subsidiary Guarantor without limitation. Each
Subsidiary Guarantor may consolidate with or merge into or sell all or
substantially all its assets to a Person other than the Company or another
 
                                       59
<PAGE>
Subsidiary Guarantor (whether or not affiliated with the Guarantor). Upon the
sale or disposition (by merger or otherwise) of a Subsidiary Guarantor (or all
or substantially all of its assets) to a Person (whether or not an Affiliate of
the Subsidiary Guarantor) which is not a Subsidiary of the Company, which sale
or disposition is otherwise in compliance with the Indenture (including the
covenant described under "--Certain Covenants--Limitation on Sales of Assets and
Subsidiary Stock"), such Subsidiary Guarantor shall be deemed released from all
its obligations under the Indenture and its Subsidiary Guarantee and such
Subsidiary Guarantee shall terminate; PROVIDED, HOWEVER, that any such
termination shall occur only to the extent that all obligations of such
Subsidiary Guarantor under the Bank Facility and all of its Guarantees of, and
under all of its pledges of assets or other security interests which secure, any
other Indebtedness of the Company shall also terminate upon such release, sale
or transfer.
 
RANKING
 
    The indebtedness evidenced by the New Notes and the Subsidiary Guarantees
will be senior obligations of the Company and the Subsidiary Guarantors,
respectively, will be unsecured (except with respect to the Escrowed Property)
and will rank PARI PASSU with the Old Notes, if any, and all other senior
unsecured Indebtedness of the Company and the Subsidiary Guarantors,
respectively, and senior to all Subordinated Obligations. Except with respect to
the Escrowed Property, the Notes and the Subsidiary Guarantees will also be
effectively subordinated to all Secured Indebtedness of the Company and the
Subsidiary Guarantors, respectively, to the extent of the value of the assets
securing such Secured Indebtedness and to all Indebtedness and other obligations
(including trade payables) of the Company's Subsidiaries other than the
Subsidiary Guarantors. The Indebtedness under the Company's Bank Facility will
be secured by substantially all the assets of the Company and its subsidiaries,
including the Rigs, other than the Escrowed Property.
 
    As of March 31, 1998, after giving pro forma effect to the Original Offering
and the application of the net proceeds therefrom, as if they had occurred on
such date, the Company and the Subsidiary Guarantors would have had no
outstanding Secured Indebtedness. However, the Bank Facility provides for
borrowing availability of $25.0 million of Secured Indebtedness of the Company
guaranteed on a secured basis by the Subsidiary Guarantors. Although the
Indenture contains limitations on the amount of additional Indebtedness that the
Company and its Restricted Subsidiaries may incur, under certain circumstances
the amount of such Indebtedness could be substantial and, under such
circumstances, such Indebtedness may be Secured Indebtedness. See "--Certain
Covenants--Limitation on Indebtedness."
 
BOOK-ENTRY, DELIVERY AND FORM
 
    The New Notes will be issued in the form of a Global Note. The Global Note
will be deposited with, or on behalf of, the Depository and registered in the
name of the Depository or its nominee. Except as set forth below, the Global
Note may be transferred, in whole and not in part, only to the Depository or
another nominee of the Depository. Investors may hold their beneficial interests
in the Global Note directly through the Depository if they have an account with
the Depository or indirectly through organizations that have accounts with the
Depository.
 
    New Notes that are issued as described below under "Certificated Notes" will
be issued in definitive certificated form. Upon the transfer of a New Note in
definitive certificated form, such New Note will, unless the Global Note has
previously been exchanged for Notes in definitive certificated form, be
exchanged for an interest in the Global Note representing the principal amount
of Notes being transferred.
 
    The Depository has advised the Company as follows: The Depository is a
limited purpose trust company organized under the laws of the State of New York,
a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code and "a clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. The
Depository was created to hold securities of institutions that have accounts
with the Depository ("participants") and to
 
                                       60
<PAGE>
facilitate the clearance and settlement of securities transactions among its
participants in such securities through electronic book-entry changes in
accounts of the participants, thereby eliminating the need for physical movement
of securities certificates. The Depository's participants include securities
brokers and dealers (which may include the Initial Purchasers), banks, trust
companies, clearing corporations and certain other organizations. Access to the
Depository's book-entry system is also available to others such as banks,
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with a participant, whether directly or indirectly.
 
    Upon the issuance of the Global Note, the Depository will credit, on its
book-entry registration and transfer system, the principal amount of the New
Notes represented by such Global Note to the accounts of participants. The
accounts to be credited initially shall be designated by or on behalf of the
Initial Purchasers. Ownership of beneficial interests in the Global Note will be
limited to participants or persons that may hold interests through participants.
Ownership of beneficial interests in the Global Note will be shown on, and the
transfer of those ownership interests will be effected only through, records
maintained by the Depository (with respect to participants' interests) and such
participants (with respect to the owners of beneficial interests in the Global
Note other than participants). The laws of some jurisdictions may require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and laws may impair the ability to transfer or
pledge beneficial interests in the Global Note.
 
    So long as the Depository, or its nominee, is the registered Holder and
owner of the Global Note, the Depository or such nominee, as the case may be,
will be considered the sole legal owner and holder of the related New Notes for
all purposes of such New Notes and the Indenture. Except as set forth below,
owners of beneficial interests in the Global Note will not be entitled to have
the New Notes represented by the Global Note registered in their names, will not
receive or be entitled to receive physical delivery of certificated New Notes in
definitive form and will not be considered to be the owners or holders of any
New Notes under the Global Note. The Company understands that under existing
industry practice, in the event an owner of a beneficial interest in the Global
Note desires to take any action that the Depository, as the holder of the Global
Note, is entitled to take, the Depository would authorize the participants to
take such action, and that the participants would authorize beneficial owners
owning through such participants to take such action or would otherwise act upon
the instructions of beneficial owners owning through them.
 
    Payment of principal of and interest on New Notes represented by the Global
Note registered in the name of and held by the Depository or its nominee will be
made to the Depository or its nominee, as the case may be, as the registered
owner and holder of the Global Note.
 
    The Company expects that the Depository or its nominee, upon receipt of any
payment of principal of or interest on the Global Note, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of the Global Note as
shown on the records of the Depository or its nominee. The Company also expects
that payments by participants to owners of beneficial interests in the Global
Note held through such participants will be governed by standing instructions
and customary practices and will be the responsibility of such participants. The
Company will not have any responsibility or liability for any aspect of the
records relating to, or payments made on account of, beneficial ownership
interests in the Global Note for any New Note or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests or for any
other aspect of the relationship between the Depository and its participants or
the relationship between such participants and the owners of beneficial
interests in the Global Note owning through such participants.
 
    Unless and until it is exchanged in whole or in part for certificated New
Notes in definitive form, the Global Note may not be transferred except as a
whole by the Depository to a nominee of such Depository or by a nominee of such
Depository to such Depository or another nominee of such Depository.
 
    Although the Depository has agreed to the foregoing procedures in order to
facilitate transfers of interests in the Global Note among participants of the
Depository, it is under no obligation to perform or
 
                                       61
<PAGE>
continue to perform such procedures, and such procedures may be discontinued at
any time. Neither the Trustee nor the Company will have any responsibility for
the performance by the Depository or its participants or indirect participants
of their respective obligations under the rules and procedures governing their
operations.
 
CERTIFICATED NOTES
 
    The New Notes represented by the Global Note are exchangeable for
certificated New Notes in definitive form of like tenor as such New Notes in
denominations of $1,000 and integral multiples thereof if (i) the Depository
notifies the Company that it is unwilling or unable to continue as Depository
for the Global Note or if at any time the Depository ceases to be a clearing
agency registered under the Exchange Act or (ii) the Company in its discretion
at any time determines not to have all of the New Notes represented by the
Global Note. Any New Note that is exchangeable pursuant to the preceding
sentence is exchangeable for certificated New Notes issuable in authorized
denominations and registered in such names as the Depository shall direct.
Subject to the foregoing, the Global Note is not exchangeable, except for a
Global Note of the same aggregate denomination to be registered in the name of
the Depository or its nominee.
 
    Neither the Company nor the Trustee will be liable for any delay by the
Depository or its nominee in indemnifying the beneficial owners of the Notes,
and the Company and the Trustee may conclusively rely on, and will be protected
in relying on, instructions from the Depository or its nominee for all purposes.
 
REGISTERED EXCHANGE OFFER; REGISTRATION RIGHTS
 
    The Issuers and the Subsidiary Guarantors have agreed pursuant to a
registration rights agreement (the "Registration Rights Agreement") with the
Initial Purchasers, for the benefit of the Holders of the Notes, that the
Issuers would, at their cost, (i) within 60 days after the Issue Date, file the
registration statement of which this Prospectus is a part (the "Exchange Offer
Registration Statement") with the SEC with respect to the Exchange Offer; and
(ii) use their reasonable best efforts to cause the Exchange Offer Registration
Statement to be declared effective under the Securities Act within 120 days
after the Issue Date. The Issuers have agreed to keep the Exchange Offer open
for not less than 30 days (or longer if required by applicable law) after the
date notice of the Exchange Offer was mailed to the Holders of the Old Notes.
For each Old Note surrendered to the Issuers pursuant to the Exchange Offer, the
Holder of such Old Note will receive a New Note having a principal amount equal
to that of the surrendered Old Note. Interest on each New Note will accrue from
the Issue Date. Under existing SEC interpretations, the New Notes would be
freely transferable by Holders other than affiliates of the Issuer after the
Exchange Offer without further registration under the Securities Act if the
Holder of the New Notes represents that it is acquiring the New Notes in the
ordinary course of its business, that it has no arrangement or understanding
with any person to participate in the distribution of the New Notes and that it
is not an affiliate of the Issuer, as such terms are interpreted by the SEC;
PROVIDED, HOWEVER, that broker-dealers ("Participating Broker-Dealers")
receiving New Notes in the Registered Exchange Offer will have a prospectus
delivery requirement with respect to resales of such New Notes. The SEC has
taken the position that Participating Broker-Dealers may fulfill their
prospectus delivery requirements with respect to New Notes (other than a resale
of an unsold allotment from the original sale of the Old Notes) with this
Prospectus. Under the Registration Rights Agreement, the Issuers are required to
allow Participating Broker-Dealers and other persons, if any, with similar
prospectus delivery requirements to use this Prospectus in connection with the
resale of such New Notes.
 
    A Holder of Old Notes who wishes to exchange such Old Notes for New Notes in
the Exchange Offer will be required to represent (i) that any New Notes to be
received by it will be acquired in the ordinary course of its business; (ii)
that at the time of the commencement of the Exchange Offer it had no arrangement
or understanding with any person to participate in the distribution (within the
meaning of the Securities Act) of the New Notes; (iii) that it is not an
"affiliate" of the Issuers, as defined in Rule 405 of the Securities Act, or if
it is an affiliate, that it will comply with the registration and prospectus
delivery
 
                                       62
<PAGE>
requirements of the Securities Act to the extent applicable; (iv) if such Holder
is not a broker-dealer, that it is not engaged in, and does not intend to engage
in, the distribution of the New Notes; and (v) if such Holder is a
broker-dealer, that it will receive New Notes for its own account in exchange
for Old Notes that were acquired as a result of market-making activities or
other trading activities and that it will be required to acknowledge that it
will deliver a Prospectus in connection with any resale of such New Notes.
 
    In the event that because of any change in law or in applicable
interpretations thereof by the staff of the Commission, the Issuers are not
permitted to effect the Exchange Offer, or the Exchange Offer is not consummated
within 150 days of the Issue Date, or if the Initial Purchasers so request with
respect to Old Notes not eligible to be exchanged for New Notes in the Exchange
Offer, or if any Initial Purchaser so requests with respect to the Old Notes not
eligible to be exchanged for New Notes and held by it following consummation of
the Exchange Offer, or if any Holder of Old Notes (other than a Participating
Broker-Dealer) is not eligible to participate in the Exchange Offer or does not
receive freely tradeable New Notes in the Exchange Offer, the Issuers will, at
their cost, (a) as promptly as practicable, file a shelf registration statement
covering resales of the Old Notes or the New Notes, as the case may be (a "Shelf
Registration Statement"), (b) use their reasonable best efforts to cause the
Shelf Registration Statement to be declared effective under the Securities Act
and (c) use their reasonable best efforts to keep the Shelf Registration
Statement continuously effective for a period of two years or such shorter
period that will terminate when all Notes covered by the Shelf Registration
Statement have been sold pursuant thereto or are no longer restricted securities
(as defined in Rule 144 under the Securities Act, or any successor rule
thereof). In the event a Shelf Registration Statement is filed, the Issuers
will, among other things, provide to each Holder for whom such Shelf
Registration Statement was filed copies of the prospectus which is a part of the
Shelf Registration Statement, notify each such Holder when the Shelf
Registration Statement has become effective and take certain other actions as
are required to permit unrestricted resales of the Notes. A Holder selling such
Notes pursuant to the Shelf Registration Statement generally would be required
to be named as a selling security holder in the related prospectus and to
deliver a prospectus to purchasers, will be subject to certain of the civil
liability provisions under the Securities Act in connection with such sales and
will be bound by the provisions of the Registration Rights Agreement which are
applicable to such Holder (including certain indemnification obligations).
 
    If after either the Exchange Offer Registration Statement or the Shelf
Registration Statement is declared effective, such Registration Statement
thereafter ceases to be effective or usable (subject to certain exceptions) in
connection with resales of Old Notes or New Notes in accordance with and during
the periods specified in the Registration Rights Agreement (a "Registration
Default"), additional interest will accrue on the Notes at the rate of 0.50% per
annum from and including the date on which any such Registration Default shall
occur to but excluding the date on which all Registration Defaults have been
cured. Such interest is payable in addition to, and at the same times as, any
other interest payable from time to time with respect to the Notes.
 
    The Issuers are entitled to close the Exchange Offer 30 days after the
commencement thereof; PROVIDED, HOWEVER, that they have accepted all Old Notes
theretofore validly tendered in accordance with the terms of the Exchange Offer.
 
    The summary herein of certain provisions of the Registration Rights
Agreement does not purport to be complete and is subject to, and is qualified in
its entirety by reference to, all the provisions of the Registration Rights
Agreement, a copy of which is available as set forth under "Available
Information."

<PAGE>
CHANGE OF CONTROL
 
    Upon the occurrence of any of the following events (each a "Change of
Control"), each Holder shall have the right to require that the Issuers
repurchase such Holder's Notes at a purchase price in cash equal to 101% of the
principal amount thereof plus accrued and unpaid interest, if any, to the date
of purchase (subject to the right of holders of record on the relevant record
date to receive interest due on the relevant Interest Payment Date):
 
        (i) any "person" (as such term is used in Sections 13(d) and 14(d) of
    the Exchange Act), other than one or more Permitted Holders, is or becomes
    the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange
    Act, except that for purposes of this clause (i) such person shall be deemed
    to have "beneficial ownership" of all shares that such person has the right
    to acquire, whether such right is exercisable immediately or only after the
    passage of time), directly or indirectly, of more than 45% of the total
    voting power of the then outstanding Voting Stock of the Company; PROVIDED,
    HOWEVER, that the Permitted Holders beneficially own (as defined above),
    directly or indirectly, in the aggregate a lesser percentage of the total
    voting power of the Voting Stock of the Company than such other person and
    do not have the right or ability by voting power, contract or otherwise to
    elect or designate for election a majority of the Board of Directors (for
    the purposes of this clause (i), such other person shall be deemed to
    beneficially own any Voting Stock of a specified corporation held by a
    parent corporation, if such other person is the beneficial owner (as defined
    in this clause (i)), directly or indirectly, of more than 45% of the voting
    power of the Voting Stock of such parent corporation and the Permitted
    Holders beneficially own (as defined above), directly or indirectly, in the
    aggregate a lesser percentage of the voting power of the Voting Stock of
    such parent corporation and do not have the right or ability by voting
    power, contract or otherwise to elect or designate for elect on a majority
    of the board of directors of such parent corporation);
 
        (ii) during any period of two consecutive years, individuals who at the
    beginning of such period constituted the Board of Directors (together with
    any new directors whose election by such Board of Directors or whose
    nomination for election by the shareholders (or members, as applicable) of
    the Company was approved by a vote of 66 2/3% of the directors of the
    Company (or the Company's managers, as applicable) then still in office who
    were either directors at the beginning of such period or whose election or
    nomination for election was previously so approved) cease for any reason to
    constitute a majority of the Board of Directors then in office; or
 
        (iii) the merger or consolidation of the Company with or into another
    Person or the merger of another Person with or into the Company, or the sale
    of all or substantially all the assets of the Company to another Person (in
    each case other than a Person that is controlled by the Permitted Holders),
    and, in the case of any such merger or consolidation, the securities of the
    Company that are outstanding immediately prior to such transaction and which
    represent 100% of the aggregate voting power of the Voting Stock of the
    Company are changed into or exchanged for cash, securities or property,
    unless pursuant to such transaction such securities are changed into or
    exchanged for, in addition to any other consideration, securities of the
    surviving corporation or a parent corporation that owns all of the capital
    stock of such corporation that represent immediately after such transaction,
    at least a majority of the aggregate voting power of the Voting Stock of the
    surviving corporation or such parent corporation, as the case may be.
 
    Within 30 days following any Change of Control, unless notice of redemption
of the Notes has been given pursuant to the provisions of the Indenture
described under "--Optional Redemption" above, the Company shall mail a notice
to the Trustee and to each Holder stating: (1) that a Change of Control has
occurred and that such Holder has the right to require the Company to purchase
such Holder's Notes at a purchase price in cash equal to 101% of the principal
amount thereof plus accrued and unpaid interest, if any, to the date of purchase
(subject to the right of holders of record on the relevant record date to
receive interest on the relevant Interest Payment Date); (2) the circumstances
and relevant facts regarding such
 
                                       64
<PAGE>
Change of Control; (3) the repurchase date (which shall be no earlier than 30
days nor later than 60 days from the date such notice is mailed); and (4) the
instructions determined by the Company, consistent with the covenant described
hereunder, that a Holder must follow in order to have its Notes repurchased.
 
    The Company shall comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations
in connection with the repurchase of Notes pursuant to the covenant described
hereunder. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of the covenant described hereunder,
the Company shall comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations under the covenant
described hereunder by virtue thereof.
 
    The Change of Control purchase feature is a result of negotiations between
the Company and the Initial Purchasers. Management has no present intention to
engage in a transaction involving a Change of Control, although it is possible
that the Company would decide to do so in the future. Subject to the limitations
discussed below, the Company could, in the future, enter into certain
transactions, including acquisitions, refinancings or other recapitalizations,
that would not constitute a Change of Control under the Indenture, but that
could increase the amount of Indebtedness outstanding at such time or otherwise
affect the Company's capital structure or credit ratings. Restrictions on the
ability of the Company and its Restricted Subsidiaries to incur additional
Indebtedness are contained in the covenant described under "--Certain
Covenants--Limitation on Indebtedness." Such restrictions can only be waived
with the consent of the Holders of a majority in principal amount of the Notes
then outstanding. Except for the limitations contained in such covenants,
however, the Indenture does not contain any covenants or provisions that may
afford Holders protection in the event of a highly leveraged transaction.
 
    If a Change of Control offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the purchase price for all
of the Notes that might be delivered by Holders seeking to accept the Change of
Control offer. The failure of the Company to make or consummate the Change of
Control offer or pay the purchase price when due will give the Trustee and the
Holders the rights described under "--Defaults."
 
    The existence of a Holder's right to require the Company to offer to
repurchase such Holder's Notes upon a Change of Control may deter a third party
from acquiring the Company in a transaction which constitutes a Change of
Control.
 
    The Bank Facility contains, and future indebtedness of the Company may
contain, prohibitions on the occurrence of certain events that would constitute
a Change of Control or require such indebtedness to be repaid or repurchased
upon a Change of Control. Moreover, the exercise by the Holders of their right
to require the Company to repurchase the Notes will cause a default under the
Bank Facility, and could cause a default under such other indebtedness, even if
the Change of Control itself does not, due to the financial effect of such
repurchase on the Company. Finally, the Company's ability to pay cash to the
Holders following the occurrence of a Change of Control may be limited by the
Company's then existing financial resources. There can be no assurance that
sufficient funds will be available when necessary to make any required
repurchases. The provisions under the Indenture relating to the Company's
obligation to make an offer to repurchase the Notes as a result of a Change of
Control may be waived or modified with the written consent of the Holders of a
majority in principal amount of the Notes.
 
CERTAIN COVENANTS
 
    The Indenture contains covenants including, among others, the following:
 
    LIMITATION ON INDEBTEDNESS.  (a) The Company shall not, and shall not permit
any Restricted Subsidiary to, Incur, directly or indirectly, any Indebtedness
unless, after giving effect to such Incurrence, the Consolidated Coverage Ratio
would exceed 2.0 to 1.0.
 
                                       65
<PAGE>
    (b) Notwithstanding the foregoing paragraph (a), the Company and the
Restricted Subsidiaries may Incur any or all of the following Indebtedness:
 
        (1) Indebtedness (including reimbursement obligations in respect of
    letters of credit outstanding under the Bank Facility that are Indebtedness)
    of the Company Incurred pursuant to the Bank Facility or any other credit or
    loan agreement (and any Guarantees in respect thereof by Restricted
    Subsidiaries that are Subsidiary Guarantors in accordance with the
    Indenture) in an aggregate principal amount which, when taken together with
    the principal amount of all other Indebtedness Incurred pursuant to this
    clause (1) and then outstanding, does not exceed $25.0 million;
 
        (2) Indebtedness of the Company or any Restricted Subsidiary owed to and
    held by the Company or any Wholly Owned Restricted Subsidiary; PROVIDED,
    HOWEVER, that any subsequent issuance or transfer of any Capital Stock which
    results in any such Wholly Owned Restricted Subsidiary ceasing to be a
    Wholly Owned Restricted Subsidiary or any subsequent transfer of such
    Indebtedness (other than to another Wholly Owned Restricted Subsidiary)
    shall be deemed, in each case, to constitute the Incurrence of such
    Indebtedness by the Company or such Restricted Subsidiary;
 
        (3) the Notes and the Subsidiary Guarantees;
 
        (4) Indebtedness outstanding on the Issue Date (other than Indebtedness
    described in clause (1), (2), or (3) of this covenant);
 
        (5) Refinancing Indebtedness in respect of Indebtedness Incurred
    pursuant to paragraph (a) or pursuant to clause (3) or (4) or this clause
    (5);
 
        (6) Hedging Obligations consisting of Interest Rate Agreements directly
    related to Indebtedness permitted to be Incurred by the Company or any
    Restricted Subsidiary pursuant to the Indenture;
 
        (7) Indebtedness of the Company or any Restricted Subsidiary consisting
    of obligations in respect of purchase price adjustments in connection with
    the acquisition or disposition of assets by the Company or any Restricted
    Subsidiary permitted under the Indenture; and
 
        (8) Indebtedness in an aggregate principal amount which, together with
    all other Indebtedness of the Company and its Restricted Subsidiaries
    outstanding on the date of such Incurrence (other than Indebtedness
    permitted by clauses (1) through (7) above or paragraph (a)), does not
    exceed $10.0 million at any one time outstanding.
 
    (c) Notwithstanding the foregoing, neither the Company nor any Restricted
Subsidiary shall Incur any Indebtedness pursuant to the foregoing paragraph (b)
if the proceeds thereof are used, directly or indirectly, to Refinance any
Subordinated Obligations unless such Indebtedness shall be subordinated to the
Notes or the Subsidiary Guarantees, as applicable, to at least the same extent
as such Subordinated Obligations.
 
    (d) For purposes of determining compliance with the covenant entitled
"--Limitation on Indebtedness," (i) in the event that an item of Indebtedness
meets the criteria of more than one of the types of Indebtedness described
above, the Company, in its sole discretion, will classify such item of
Indebtedness and only be required to include the amount and type of such
Indebtedness in one of the above clauses and (ii) an item of Indebtedness may be
divided and classified in more than one of the types of Indebtedness described
above.
 
    LIMITATION ON LIENS.  The Company shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, create or permit to exist any
Lien upon any of its property or assets, now owned or hereafter acquired,
securing any obligation unless concurrently with the creation of such Lien
effective provision is made to secure the Notes and the Subsidiary Guarantees
equally and ratably with such obligation for so long as such obligation is so
secured; PROVIDED, HOWEVER, that, if such obligation is a Subordinated
Obligation, the Lien securing such obligation shall be subordinated and junior
to the Lien
 
                                       66
<PAGE>
securing the Notes and the Subsidiary Guarantees with the same or lesser
relative priority as such Subordinated Obligation shall have been with respect

                                       69
<PAGE>
Restricted Subsidiary, as the case may be) (A) First, to either (i) prepay,

balance of such Net Available Cash after application in accordance with clauses
(A) or (B) to any other application or use not prohibited by the Indenture.
Notwithstanding the foregoing provisions of this paragraph, the Company and the
Restricted Subsidiaries shall not be required to apply the Net Available Cash in
accordance with this paragraph except to the extent that the aggregate Net
Available Cash from all Asset Dispositions which is not applied in accordance
with this paragraph exceeds $5.0 million (at which time, the entire unutilized
Net Available Cash, and not just the amount in excess of $5.0 million, shall be
applied pursuant to this paragraph). Pending application of Net Available Cash
pursuant to this covenant, such Net Available Cash shall be invested in
Permitted Investments.

purchase Notes tendered pursuant to an offer by the Company for the Notes at a
purchase price of 100% of their principal amount plus accrued but unpaid
interest in accordance with the procedures (including prorating in the event of

Notes tendered pursuant to such offer is less than the Net Available Cash
allotted to the purchase thereof, the Company will be required to apply the
remaining Net Available Cash in accordance with clause (a)(ii)(C) above. The
Company shall not be required to make such an offer to purchase Notes pursuant
to this covenant if the Net Available Cash available therefor is less than $5.0
million (which lesser amount shall be carried forward for purposes of
determining whether such an offer is required with respect to any subsequent
Asset Disposition).
 
    (c) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Notes pursuant to this
covenant. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this covenant, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under this clause by virtue thereof.

subject to the conditions contained in the Indenture; and (iii) THIRD, to the
extent of the balance of such Event of Loss Proceeds after application in
accordance with clauses (i) or (ii) to any other application or use not
prohibited by the
 
                                       70
<PAGE>
Indenture. Pending application of Event of Loss Proceeds pursuant to this
covenant, such Event of Loss Proceeds shall be invested in Permitted
Investments.
 
    (b) In the event of an Event of Loss that requires the purchase of the Notes
pursuant to clause (a)(ii) above, the Company will be required to purchase Notes
tendered pursuant to an offer by the Company for the Notes at a purchase price
of 101% of their principal amount plus accrued but unpaid interest in accordance
with the procedures (including prorating in the event of oversubscription) set
forth in the Indenture. If the aggregate purchase price of Notes tendered
pursuant to such offer is less than the Event of Loss Proceeds allotted to the
purchase thereof, the Company will be required to apply the remaining Event of
Loss Proceeds in accordance with clause (a)(iii) above.
 
    (c) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Notes pursuant to this
covenant. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this covenant, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under this clause by virtue thereof.
 
    INSURANCE.  The Company shall, or shall cause the Restricted Subsidiary
owning a drilling rig or drilling rigs to, carry and maintain with respect to
each Rig owned by it insurance payable in United States Dollars in amounts,
against risks (including marine hull and machinery (including excess value)
insurance, marine protection and indemnity insurance, war risks insurance and
liability insurance and liability arising out of pollution and the spillage or
leakage of cargo and cargo liability insurance) and in a form which is
substantially equivalent to the coverage carried by other responsible and
experienced companies engaged in the operation of drilling rigs similar to the
Rigs and with insurance companies, underwriters, funds, mutual insurance
associations or clubs of recognized standing. No insurance shall provide for a
deductible in excess of $1.0 million per occurrence. No insurance policy shall
be subject to lapse without at least seven Business Days' prior notice to the
Trustee.
 
    For purposes of insurance against total loss, each drilling rig is to be
insured for an amount not less than the fair market value (as determined in good
faith by the Board of Directors of the Company) and not less, when aggregated
with the insurance on the other drilling rigs, than the outstanding principal
amount of the Notes, Indebtedness under the Bank Facility and any other PARI
PASSU Indebtedness, in each case together with premium, if any, and accrued
interest thereon.
 
    LIMITATION ON TRANSACTIONS WITH AFFILIATES.  (a) The Company shall not, and

rendering of any service) with any Affiliate of the Company other than the
Company or a Restricted Subsidiary (an "Affiliate Transaction") unless the terms
thereof (1) are no less favorable to the Company or such Restricted Subsidiary
than those that could be obtained at the time of such transaction in a
comparable transaction in arm's-length dealings with a Person who is not such an
Affiliate, (2) if such Affiliate Transaction involves an amount in excess of
$1.0 million, (i) are set forth in writing and (ii) have been approved by a

"Change of Control" (in either case, other than a failure to purchase Notes) or
under "--Certain Covenants--Limitation on Indebtedness," "--Limitation on
Restricted Payments," "--Limitation on Restrictions on Distributions from
Restricted Subsidiaries," "--Limitation on Sales of Assets and Subsidiary
Stock," "--Insurance," "--Limitations on Transactions with Affiliates,"
"--Limitation on the Sale or Issuance of Capital Stock of Restricted
Subsidiaries," "--Limitation on Business Activities," "-- Future Subsidiary
Guarantors," "--Limitation on Finance," "--Impairment of Security Interest in
Collateral" and "--Amendments to Escrow Agreement and Escrow Security
Agreement," (v) the failure by the Company to comply for 60 days after the
Company receives written notice with its other agreements contained in the
Indenture, (vi) Indebtedness of the Company or any Restricted Subsidiary is not
paid within any applicable grace period after final maturity or is accelerated
by the Holders thereof because of a default and the total amount of such
Indebtedness unpaid or accelerated exceeds $10.0 million (the "cross
acceleration provision"), (vii) certain events of bankruptcy, insolvency or
reorganization of the Company or any Restricted Subsidiary that is a Significant
Subsidiary (the "bankruptcy provisions"), (viii) any judgment or decree for the
payment of money in excess of $10.0 million is entered against the Company or
any Restricted Subsidiary, remains outstanding for a period of 60 days following
entry of such judgment and is not discharged, bonded, waived or stayed within 30
days after notice (the "judgment default provision"), (ix) a Subsidiary
Guarantee ceases to be in full force and effect (other than in accordance with
the terms of such Subsidiary Guarantee or the Indenture) or a Subsidiary
Guarantor denies or disaffirms its obligations under its Subsidiary Guarantee
(the "guarantee default provision"), or (x) the security interest under the
Escrow Security Agreement shall, at any time, cease to be in full force and
effect for any reason (other than by operation of the provisions of the
Indenture and the Escrow Security Agreement), or any security interest created
thereunder shall be declared invalid or unenforceable, or the Company or any
Restricted Subsidiary shall assert, in any pleading in any court of competent
jurisdiction that any such security interest is invalid or unenforceable (the
"security default provision"). However, a default under clause (iv) or (v) will
not constitute an Event of Default until the Trustee or the Holders of 25% in
principal amount of the outstanding Notes notify the Company of the default and
the Company does not cure such default within the time specified after receipt
of such notice.
 
    If an Event of Default (other than the bankruptcy provisions relating to the
Company) occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the outstanding Notes may declare the principal of and
accrued but unpaid interest on all the Notes to be due and payable. Upon such a
declaration, such principal and interest shall be due and payable immediately.
If an Event of Default relating to the bankruptcy provisions relating to the
Company occurs and is continuing, the principal of and interest on all the Notes
will IPSO FACTO become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders. The Holders
of a majority in principal amount of the outstanding Notes may by notice to the
Trustee rescind any acceleration and its consequences if the rescission would
not conflict with any judgment or decree and if all existing Events of Default
have been cured or waived except non-payment of principal or interest that has
become due solely because of acceleration. No such rescission shall affect any
subsequent Default or impair any right consequent thereto.
 
    Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default occurs and is continuing, the Trustee will
be under no obligation to exercise any of the rights or powers under the
Indenture at the request or direction of any of the Holders unless such Holders
have offered to the Trustee reasonable indemnity or security against any loss,
liability or expense. Except to
 
                                       74
<PAGE>
enforce the right to receive payment of principal, premium (if any) or interest
when due, no Holder of a Note may pursue any remedy with respect to the
Indenture or the Notes unless (i) such Holder has previously given the Trustee
notice that an Event of Default is continuing, (ii) Holders of at least 25% in
principal amount of the outstanding Notes have requested the Trustee to pursue
the remedy, (iii) such Holders have offered the Trustee reasonable security or
indemnity against any loss, liability or expense, (iv) the Trustee has not
complied with such request within 60 days after the receipt thereof and the
offer of security or indemnity and (v) the Holders of a majority in principal
amount of the outstanding Notes have not given the Trustee a direction
inconsistent with such request within such 60-day period. Subject to certain
restrictions, the Holders of a majority in principal amount of the outstanding
Notes are given the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or of exercising any trust or
power conferred on the Trustee. The Trustee, however, may refuse to follow any
direction that conflicts with law or the Indenture or that the Trustee
determines is unduly prejudicial to the rights of any other Holder or that would
involve the Trustee in personal liability.
 
    The Indenture provides that if a Default occurs and is continuing and is
known to the Trustee, the Trustee must mail to each Holder notice of the Default
within 90 days after it occurs. Except in the case of a Default in the payment
of principal of or interest on any Note, the Trustee may withhold notice if and
so long as the board of directors, the executive committee or a committee of its
trust officers determines that withholding notice is not opposed to the interest
of the Holders. In addition, the Company is required to deliver to the Trustee,
within 120 days after the end of each fiscal year, a certificate indicating
whether the signers thereof know of any Default that occurred during the
previous year. The Company also is required to deliver to the Trustee, within 30
days after the occurrence thereof, written notice of any event that would
constitute certain Defaults, their status and what action the Company is taking
or proposes to take in respect thereof.
 
AMENDMENTS AND WAIVERS
 
    Subject to certain exceptions, the Indenture may be amended with the consent
of the Holders of a majority in principal amount of the Notes then outstanding
(including consents obtained in connection with a tender offer or exchange offer
for the Notes) and any past default or compliance with any provisions may also
be waived with the consent of the Holders of a majority in principal amount of
the Notes then outstanding.
 
    Without the consent of each Holder of an outstanding Note affected thereby,
no amendment may (i) reduce the amount of Notes whose Holders must consent to an
amendment, (ii) reduce the rate of or extend the time for payment of interest on
any Note, (iii) reduce the principal of or extend the Stated Maturity of any
Note, (iv) reduce the premium payable upon the redemption of any Note or change
the time at which any Note may be redeemed as described under "--Redemption"
above, (v) make any Note payable in money other than that stated in the Note,
(vi) impair the right of any Holder to receive payment of principal of and
interest on such Holder's Notes on or after the due dates therefor or to
institute suit for the enforcement of any payment on or with respect to such
Holder's Notes, (vii) make any change in the amendment provisions which require
each Holder's consent or in the waiver provisions, (viii) affect the ranking of
the Notes in any material respect or (ix) make any change in any Subsidiary
Guarantee or the Escrow Security Agreement that would adversely affect the
Holders or terminate the Lien of the Indenture or the Escrow Security Agreement
on the Collateral or deprive the Holders of the security afforded by such Lien.
 
    Without the consent of any Holder, the Company and the Trustee may amend the
Indenture to cure any ambiguity, omission, defect or inconsistency, to provide
for the assumption by a successor corporation of the obligations of the Company
under the Indenture, to provide for uncertificated Notes in addition to or in
place of certificated Notes (provided that the uncertificated Notes are issued
in registered form for purposes of Section 163(f) of the Code, or in a manner
such that the uncertificated Notes are described in Section 163(f)(2)(B) of the
Code), to add guarantees with respect to the Notes, to secure the Notes, to add
 
                                       75
<PAGE>
to the covenants of the Company for the benefit of the Holders or to surrender
any right or power conferred upon the Company, to make any change that does not
adversely affect the rights of any Holder or to comply with any requirement of
the SEC in connection with the qualification of the Indenture under the Trust
Indenture Act.
 
    The consent of the Holders is not necessary under the Indenture to approve
the particular form of any proposed amendment. It is sufficient if such consent
approves the substance of the proposed amendment.
 
    After an amendment under the Indenture becomes effective, the Company is
required to mail to Holders a notice briefly describing such amendment. However,
the failure to give such notice to all Holders, or any defect therein, will not
impair or affect the validity of the amendment.
 
TRANSFER
 
    The New Notes will be issued in registered form and will be transferable
only upon the surrender of the New Notes being transferred for registration of
transfer. The Company may require payment of a sum sufficient to cover any tax,
assessment or other governmental charge payable in connection with certain
transfers and exchanges. The Company is not required to transfer or exchange any
Note selected for redemption or repurchase or to transfer or exchange any Note
for a period of 15 days prior to selection of Notes to be redeemed or
repurchased.
 
DEFEASANCE
 
    The Issuers at their option at any time may terminate all of their
obligations under the Notes and the Indenture ("legal defeasance"), except for
certain obligations, including those respecting the defeasance trust and
obligations to register the transfer or exchange of the Notes, to replace
mutilated, destroyed, lost or stolen Notes and to maintain a registrar and
paying agent in respect of the Notes. In addition, the Issuers at their option
at any time may terminate their obligations under "--Change of Control" and
under the covenants described under "--Certain Covenants" (other than the
covenant described under "--Merger and Consolidation") (and any omission to
comply with such obligations shall not constitute a Default or Event of Default
with respect to the Notes), the operation of the cross acceleration provision,
the bankruptcy provisions with respect to Significant Subsidiaries and the
judgment default provision, the guarantee default provision and the security
default provision described under "--Defaults" above and the limitations
contained in clauses (iii) and (iv) of the first paragraph under "--Certain
Covenants--Merger and Consolidation" above ("covenant defeasance").
 
    The Issuers may exercise their legal defeasance option notwithstanding their
prior exercise of their covenant defeasance option. If the Issuers exercise
their legal defeasance option, payment of the Notes may not be accelerated
because of an Event of Default with respect thereto. If the Issuers exercise
their covenant defeasance option, payment of the Notes may not be accelerated
because of an Event of Default specified in clause (iv), (vi), (vii) (with
respect only to Significant Subsidiaries) or (viii), (ix) and (x) under
"--Defaults" above or because of the failure of the Company to comply with
clause (iii) or (iv) of the first paragraph under "--Certain Covenants--Merger
and Consolidation" above. If the Issuers exercise their legal defeasance option
or their covenant defeasance option, each Subsidiary Guarantor will be released
from all its obligations with respect to its Subsidiary Guarantee.
 
    In order to exercise either defeasance option, the Issuers must irrevocably
deposit in trust (the "defeasance trust") with the Trustee money or U.S.
Government Obligations for the payment of principal of and interest on the Notes
to redemption or maturity, as the case may be, and must comply with certain
other conditions, including delivery to the Trustee of an Opinion of Counsel to
the effect that Holders will not recognize income, gain or loss for Federal
income tax purposes as a result of such deposit and defeasance and will be
subject to Federal income tax on the same amount and in the same manner and at
the same times as would have been the case if such deposit and defeasance had
not occurred (and, in the case of legal defeasance only, such Opinion of Counsel
must be based on a ruling of the Internal Revenue Service or other change in
applicable Federal income tax law).
 
                                       76
<PAGE>
SATISFACTION AND DISCHARGE
 
    The Indenture will cease to be of further effect (except as to surviving
rights of registration of transfer or exchange of the Notes, as expressly
provided for in the Indenture) as to all outstanding Notes when: (i) either (a)
all the Notes theretofore authenticated and delivered (except lost, stolen or
destroyed Notes which have been replaced or paid) have been delivered to the
Trustee for cancellation or (b) all Notes not theretofore delivered to the
Trustee for cancellation have become due and payable and the Issuers have
irrevocably deposited or caused to be deposited with the Trustee an amount in
United States dollars sufficient to pay and discharge the entire indebtedness on
the Notes not theretofore delivered to the Trustee for cancellation, for the
principal of, premium, if any, and interest to the date of deposit; (ii) the
Issuers have paid or caused to be paid all other sums payable under the
Indenture by the Issuers; and (iii) the Issuers have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel each stating that all conditions
precedent under the Indenture relating to the satisfaction and discharge of the
Indenture have been complied with.
 
NO PERSONAL LIABILITY
 
    The Indenture provides that no recourse for the payment of the principal of,
premium, if any, or interest on any of the Notes or for any claim based thereon
or otherwise in respect thereof, and no recourse under or upon any obligation,
covenant or agreement of the Issuers in the Indenture, or in any of the Notes or
because of the creation of any Indebtedness represented thereby, shall be had
against any incorporator, stockholder, member, officer, director, manager,
employee or controlling person of the Issuers or any successor Person thereof.
 
    Each Holder, by accepting the Notes, waives and releases all such liability.
Such waiver may not be effective to waive liabilities under the federal
securities laws and it is the view of the SEC that such waiver is against public
policy.
 
CONCERNING THE TRUSTEE
 
    U.S. Bank Trust National Association is the Trustee under the Indenture, the
Escrow Agent under the Escrow Agreement and the Collateral Agent under the
Escrow Security Agreement and has been appointed by the Company as Registrar and
Paying Agent with regard to the Notes. Such bank may also act as a depository of
funds for, or make loans to and perform other services for, the Company or its
affiliates in the ordinary course of business in the future. The corporate trust
office of the Trustee is located at 100 Wall Street, New York, New York 10041.
 
    The Holders of a majority in principal amount of the outstanding Notes will
have the right to direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee, subject to certain
exceptions. The Indenture provides that if an Event of Default occurs (and is
not cured), the Trustee will be required, in the exercise of its power, to use
the degree of care of a prudent man in the conduct of his own affairs. Subject
to such provisions, the Trustee will be under no obligation to exercise any of
its rights or powers under the Indenture at the request of any Holder of Notes,
unless such Holder shall have offered to the Trustee security and indemnity
satisfactory to it against any loss, liability or expense and then only to the
extent required by the terms of the Indenture. The Trustee may resign at any
time or may be removed by the Company. If the Trustee resigns, is removed or
becomes incapable of acting as Trustee or if a vacancy occurs in the office of
the Trustee for any cause, a successor Trustee shall be appointed in accordance
with the provisions of the Indenture.
 
    If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and the Indenture. The Indenture also
contains certain limitations on the right of the Trustee, as a creditor of the
Company, to obtain payment of claims in certain cases, or to realize on certain
property received by it in respect of any such claims, as security or otherwise.
 
                                       77

GOVERNING LAW
 
    The Indenture provides that it and the Notes will be governed by, and
construed in accordance with, the laws of the State of New York without giving
effect to applicable principles of conflicts of law to the extent that the
application of the law of another jurisdiction would be required thereby.

of Indebtedness, or both, EBITDA and Consolidated Interest Expense for such
period shall be calculated after giving effect on a pro forma basis to such

<PAGE>
attributable to the assets which are the subject of such Asset Disposition for

occurred on the first day of such period or (4) if since the beginning of such
period any Person (that subsequently became a Restricted Subsidiary or was
merged with or into the Company or any Restricted Subsidiary since the beginning
of such period) shall have made any Asset Disposition, Investment or acquisition
of assets that would have required an adjustment pursuant to clause (2) or (3)
above if made by the Company or a Restricted Subsidiary during such period,
EBITDA and Consolidated Interest Expense for such period shall be calculated
after giving pro forma effect thereto as if such Asset Disposition, Investment
or acquisition occurred on the first day of such period. For purposes of this
definition, whenever pro forma effect is to be given to an acquisition of
assets, the amount of income or earnings relating thereto and the amount of
Consolidated Interest Expense associated with any Indebtedness Incurred in
connection therewith, the pro forma calculations shall be determined in good
faith by a responsible financial or accounting officer of the Company. If any
Indebtedness bears a floating rate of interest and is being given pro forma
effect, the interest on such Indebtedness shall be calculated as if the rate in
effect on the date of determination had been the applicable rate for the entire
period (taking into account any Interest Rate Agreement applicable to such
Indebtedness if such Interest Rate Agreement has a remaining term in excess of
12 months). For purposes of this definition, in the case of the acquisition
since the beginning of such period of a drilling rig (or a Restricted Subsidiary
owning a rig) by the Company or by a Restricted Subsidiary pursuant to a binding
purchase agreement or the delivery since the beginning of such period of a
drilling rig to the Company or a Restricted Subsidiary pursuant to a drilling
rig construction contract, if such drilling rig is subject to a binding drilling
contract, the Company shall give pro forma effect to the earnings (losses) of
such drilling rig as if such drilling rig was acquired on the first day of such
period by basing such earnings (losses) on (A) (x) revenues to be earned from
any binding drilling contract of at least one year's duration that will be
applicable to any such drilling rig (including a drilling rig owned by a
Restricted Subsidiary) and in effect during such period and (y) a good faith
estimate of the operating costs of such drilling rig (as determined in the
reasonable judgment of a responsible financial officer of the Company) or (B)

than one year's duration, the earnings (losses) for such period based on
industry average earning (losses) for comparable drilling rigs (as determined in
the reasonable judgment of a responsible financial officer of the Company).

distribution paid to a Restricted Subsidiary, to the limitations contained in
clause (iii) below) and (B) with respect to the calculation of EBITDA only, the
Company's equity in a net loss of any such Person for such period shall be

invested by the Company or any Restricted Subsidiary in such Person during such
period; (ii) any net income (or loss) of any Person acquired by the Company or a

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
    The following discussion is a summary of certain federal income tax
considerations relevant to the exchange of Old Notes for New Notes, but does not
purport to be a complete analysis of all potential tax effects. The analysis is
based upon the Code, Treasury regulations, Internal Revenue Service rulings and
pronouncements, and judicial decisions now in effect, all of which are subject
to change at any time by legislative, judicial or administrative action. Any
such changes may be applied retroactively in a manner that could adversely
affect a Holder of the New Notes. The description does not consider the effect
of any applicable foreign, state, local or other tax laws or estate or gift tax
considerations.
 
    EACH HOLDER SHOULD CONSULT ITS OWN TAX ADVISOR AS TO THE PARTICULAR TAX
CONSEQUENCES TO IT OF EXCHANGING OLD NOTES FOR NEW NOTES, INCLUDING THE
APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS.
 
EXCHANGE OF OLD NOTES FOR NEW NOTES
 
    The exchange of Old Notes for New Notes pursuant to the Exchange Offer
should not constitute a material modification of the terms of the Old Notes and,
therefore, such exchange should not constitute an exchange for federal income
tax purposes. Accordingly, such exchange should have no federal income tax
consequences to Holders of Old Notes.
 
                              PLAN OF DISTRIBUTION
 
    Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of New Notes received in exchange for Old Notes where
such Old Notes were acquired as a result of market-making activities or other
trading activities. The Issuers have agreed that, for a period of 180 days after
the Expiration Date, they will make this Prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resale. In
addition, until November     , 1998, all dealers effecting transactions in the
New Notes may be required to deliver a prospectus.
 
    The Issuers will not receive any proceeds from any sale of New Notes by
broker-dealers. New Notes received by broker-dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the New Notes or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer or the purchasers of any such New Notes. Any broker-dealer that
resells New Notes that were received by it for its own account pursuant to the
Exchange Offer and any broker or dealer that participates in a distribution of
such New Notes may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit on any such resale of New Notes and any
commissions or concessions received by any such persons may be deemed to be
underwriting compensation under the Securities Act. The Letter of Transmittal
states that, by acknowledging that it will deliver and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.
 
    For a period of 180 days after the Expiration Date the Issuers will promptly
send additional copies of this Prospectus and any amendment or supplement to
this Prospectus to any broker-dealer that requests such documents in the Letter
of Transmittal. The Issuers have agreed to pay all expenses incident to the
Exchange Offer (including the expenses of one counsel for the Holders of the
Notes) other than commissions or concessions of any brokers or dealers and will
indemnify the Holders of the Notes (including any broker-dealers) against
certain liabilities, including liabilities under the Securities Act.

                          NOTICE TO CANADIAN RESIDENTS
 
RESALE RESTRICTIONS
 
    The distribution of the Notes in Canada is being made only on a private
placement basis exempt from the requirement that the Issuers prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of Notes are effected. Accordingly, any resale of the Notes in Canada
must be made in accordance with applicable securities laws which will vary
depending on the relevant jurisdiction, and which may require resales to be made
in accordance with available statutory exemptions or pursuant to a discretionary
exemption granted by the applicable Canadian securities regulatory authority.
Purchasers are advised to seek legal advice prior to any resale of the Notes.
 
REPRESENTATIONS OF PURCHASERS
 
    Each purchaser of Notes in Canada who receives a purchase confirmation will
be deemed to represent to the Issuers and the dealer from whom such purchase
confirmation is received that (i) such purchaser is entitled under applicable
provincial securities laws to purchase such Notes without the benefit of a
prospectus qualified under such securities laws, (ii) where required by law,
that such purchaser is purchasing as principal and not as agent and (iii) such
purchaser has reviewed the text above under "Resale Restrictions."
 
RIGHTS OF ACTION (ONTARIO PURCHASERS)
 
    The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Section 32 of the Regulation under the SECURITIES ACT (Ontario). As a result,
Ontario purchasers must rely on other remedies that may be available, including
common law rights of action for damages or rescission or rights of action under
the civil liability provisions of the U.S. federal securities laws. Following a
decision of the U.S. Supreme Court, it is possible that Ontario purchasers will
not be able to rely upon the remedies set out in Section 12(2) of the United
States Securities Act of 1933 where securities are being offered under a U.S.
private placement memorandum such as this document.
 
ENFORCEMENT OF LEGAL RIGHTS
 
    All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be possible
for Canadian purchasers to effect service of process within Canada upon the
issuer or such persons. All or a substantial portion of the assets of the issuer
and such persons may be located outside of Canada and, as a result, it may not
be possible to satisfy a judgment against the issuer or such persons in Canada
or to enforce a judgment obtained in Canadian courts against such issuer or
persons outside of Canada.
 
NOTICE TO BRITISH COLUMBIA RESIDENTS
 
    A purchaser of Notes to whom the SECURITIES ACT (British Columbia) applies
is advised that such purchaser is required to file with the British Columbia
Securities Commission a report within ten days of the sale of any Notes acquired
by such purchaser pursuant to the Offering. Such report must be in the form
attached to British Columbia Securities Commission Blanket Order BOR #95/17, a
copy of which may be obtained from the Company. Only one such report must be
filed in respect of Notes acquired on the same date and under the same
prospectus exemption.
 
TAXATION AND ELIGIBILITY FOR INVESTMENT
 
    Canadian purchasers of Notes should consult their own legal and tax advisors
with respect to the tax consequences of an investment in the Notes in their
particular circumstance and with respect to the eligibility of the Notes for
investment by the purchaser under the relevant Canadian legislation.

                                 LEGAL MATTERS
 
    Certain legal matters with respect to the New Notes and Subsidiary
Guarantees offered hereby will be passed upon for the Company by Weil, Gotshal &
Manges LLP, 700 Louisiana, Suite 1600, Houston, Texas 77002.
 
                                    EXPERTS
 
    The financial statements of the Company as of December 31, 1997, and for the
period from inception (August 5, 1997) to December 31, 1997, included in this
Prospectus and elsewhere in the registration statement have been audited by
Arthur Andersen LLP, independent public accountants, as indicated in their
report with respect thereto (which contains an explanatory paragraph describing
conditions that raise substantial doubt about the Company's ability to continue
as a going concern as described in Note 1 to the financial statements), and are
included herein in reliance upon the authority of said firm as experts in giving
said report.
 
                             AVAILABLE INFORMATION
 
    As a result of the filing of their Registration Statement with the
Securities and Exchange Commission (the "Commission"), the Issuers and the
Guarantors will become subject to the informational reporting requirements of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and, in
accordance therewith, will be required to file reports and other information
with the Commission. Such reports and other information can be inspected and
copied at the principal office of the Commission at Judiciary Plaza, 450 Fifth
Street, N.W., Washington, D.C. 20549, and the following Regional Offices of the
Commission: Chicago Regional Office, Northwestern Atrium Center, 500 West
Madison Street, Suite 1400, Chicago, Illinois 60611 and New York Regional
Office, 7 World Trade Center, 13th Floor, New York, New York 10048. Copies of
such material may also be obtained at prescribed rates from the Public Reference
Section of the Commission at its principal office at Judiciary Plaza, 450 Fifth
Street, N.W., Washington, D.C. 20549. The Commission also maintains a Web site
that contains reports, proxy and information statements and other information
regarding registrants that file electronically with the Commission at
http://www.sec.gov.
 
    The Issuers and the Guarantors have filed with the Commission a Registration
Statement (which term shall encompass any amendments thereto) on Form S-4 under
the Securities Act with respect to the securities offered hereby. This
Prospectus does not contain all information set forth in the Registration
Statement and the exhibits thereto, to which reference is hereby made. Although
the Company believes that statements made in this Prospectus as to the contents
of any contract, agreement or other document describe all material elements of
such documents, such statements are not necessarily complete. With respect to
each such contract, agreement or other document filed as an exhibit to the
Registration Statement, reference is hereby made to such exhibit for a more
complete description of the matter involved, and each such statement shall be
deemed qualified in its entirety by such reference.
 
    The Company will furnish holders of the securities offered hereby with
annual reports containing, among other information, audited financial statements
certified by an independent public accounting firm and quarterly reports
containing unaudited financial information for the first three quarters of each
fiscal year. The Company will also furnish such other reports as it may
determine or as may be required by law or by the Indenture, in each case from
and after the effective date of the Registration Statement. Based upon certain
provisions of the Staff Accounting Bulletins of the Commission and
interpretations of the staff of the Commission set forth in no-action letters
issued to third parties unrelated to the Issuers and the Guarantors, Finance and
the Guarantors do not intend to file separate periodic and other reports with
the Commission under the Exchange Act because (i) the Company is a holding
company with no independent operations, (ii) the Guarantors are direct
wholly-owned consolidated subsidiaries of the Company that will fully and
unconditionally guarantee the New Notes on a joint and several basis and (iii)
Finance and the Guarantors comprise all of the Company's direct and indirect
subsidiaries.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Members of
Chiles Offshore LLC:
 
    We have audited the accompanying balance sheet of Chiles Offshore LLC (a
Delaware limited liability company in the development stage) as of December 31,
1997, and the related statements of operations, members' equity and cash flows
for the period from inception (August 5, 1997) to December 31, 1997. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Chiles Offshore LLC as of
December 31, 1997, and the results of its operations and its cash flows for the
period from inception (August 5, 1997) to December 31, 1997, in conformity with
generally accepted accounting principles.
 
    The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As shown in the accompanying financial
statements, the Company is a development-stage enterprise with no significant
operating results to date. The factors discussed in Note 1 to the financial
statements raise a substantial doubt about the ability of the Company to
continue as a going concern. Management's plans in regards to those matters are
also described in Note 1. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
 
1. ORGANIZATION AND BUSINESS:
 
    Chiles Offshore LLC (Chiles or the Company) is engaged in the construction
of offshore drilling rigs which will be contracted to oil and gas operators upon
completion of construction. The Company was formed under the laws of the state
of Delaware on August 5, 1997. The duration of the Company is 35 years from the
date of formation.
 
    On August 5, 1997, two members, Group A and Group B, entered into the
Operating Agreement of Chiles Offshore LLC (the Operating Agreement) for the
purpose of forming the Company. Group A and Group B each made capital
contributions of $8,850,000 and received a 50 percent percentage interest, as
defined in the Operating Agreement, in the Company. Additionally, the president
of Group B was hired as president of the Company.
 
    Group A's capital contribution consisted of $8,850,000 in cash, which was
paid directly to third parties on behalf of the Company. Group B's capital
contribution consisted of $364,000 in cash and net assets with an agreed-upon
value of $8,486,000. The value of Group B's net assets was mutually agreed upon
by Group A and Group B based upon Group B's construction contract rights,
construction in progress and shipyard slots secured through such construction
contracts. The historical cost of such net assets contributed by Group B was
$2,256,000. Accordingly, the difference between the agreed-upon value and
historical cost of Group B's net assets, $6,230,000, has been recorded in the
accompanying balance sheet as rigs under construction and equipment.
 
    On December 16, 1997, in accordance with the Amended and Restated Agreement
of Chiles Offshore LLC (the Agreement) another member group, Group C contributed
capital of $20,000,000 in cash for a percentage interest in the Company. Also on
December 16, 1997, Group A contributed additional capital of $26,150,000
consisting of $12,158,284 in cash and advances Group A had made to the Company
in the amount of $13,991,716. In accordance with the Agreement and effective
December 16, 1997, the percentage interests in the Company were 55.38 percent,
13.85 percent and 30.77 percent for Group A, Group B and Group C, respectively.
 
    The contributions of Groups A, B and C resulted in the issuance to these
members of membership interests in the Company. Membership interest is the
member's limited liability company interest in the Company which refers to all
of a member's rights and interest in the Company in such member's capacity as a
member, all as provided in the Agreement and the Delaware Limited Liability
Company Act. In conjunction with the issuance of the membership interest to a
member, the member received a percentage interest in the Company. The percentage
interest of a member means the aggregate limited liability company percentage
interest set forth in the Agreement, as modified from time to time.
 
    The Company has operated as a development stage company since its inception
by devoting substantially all of its efforts to designing, engineering and
contracting with shipyards and vendors for two offshore drilling rigs, raising
capital and securing contracts for the rigs. The Company has not generated
revenues, nor is there any assurance that the Company will generate significant
revenues in the future. In addition, there can be no assurance that the Company
will successfully complete the transition from a development stage company to
successful operations. Additional risk factors associated with the Company's
operations include, but are not limited to, oil and gas prices, capital
expenditure plans of oil and gas operators, access to capital, completion of
construction of the rigs and competition. As a result of the aforementioned
factors and the related uncertainties, there can be no assurance of the
Company's future success.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
1. ORGANIZATION AND BUSINESS: (CONTINUED)
    The Company has a loss from operations of $382,042 for the period from
inception to December 31, 1997. Management is currently pursuing a business
strategy which includes obtaining drilling contracts with oil and gas operators,
employment of rig personnel, obtaining additional financing to complete the
construction of the rigs and fund the purchase of drilling equipment, and
overseeing the construction of the rigs and installation of the drilling
equipment. There are no assurances that this business strategy will be achieved.
While pursuing this business strategy, the Company will experience cash flow
deficits until the rig construction is completed and the rigs are placed in
operation. As a result of the aforementioned factors and related uncertainties,
there is substantial doubt as to the Company's ability to continue as a going
concern. The financial statements do not include any adjustments relating to the
recoverability and classification of asset carrying amounts or the amount and
classification of liabilities that might result should the Company be unable to
continue as a going concern.
 
2. SIGNIFICANT ACCOUNTING POLICIES:
 
CASH AND CASH EQUIVALENTS
 
    For purposes of reporting cash flows, all liquid investments with maturities
at the date of purchase of three months or less are considered cash equivalents.
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
PROPERTY, EQUIPMENT AND REALIZATION OF LONG-LIVED ASSETS
 
    Property and equipment includes costs incurred for the construction of the
rigs, including internal expenditures relating to construction support. All
expenditures not related to construction are expensed in the accompanying
Statements of Operations. Disposals are removed at cost less accumulated
depreciation, and any resulting gain or loss is reflected in the accompanying
statement of operations. Depreciation is calculated from the date the asset is
placed in service, using the straight-line method over the estimated useful
lives of the depreciable assets, which range from three to 25 years. The Company
capitalizes interest applicable to the construction of the rigs as a cost of
such assets. The Company has included in the property and equipment account all
costs incurred to support the construction of the rigs. Depreciation expense for
the period ended December 31, 1997, was $5,953.
 
    In March 1995, Statement of Financial Accounting Standards (SFAS) No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of," was issued. SFAS No. 121, which became effective in 1996,
requires that certain long-lived assets be reviewed for impairment whenever
events indicate that the carrying amount of an asset may not be recoverable and
that an impairment loss be recognized under certain circumstances in the amount
by which the carrying value

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
exceeds the fair value of the asset. The Company adopted SFAS No. 121 in 1996,
and the adoption had no effect on the Company's results of operations or
consolidated financial position.
 
INCOME TAXES
 
    No provision for income taxes is made since the Company is treated as a
partnership for tax purposes, and such taxes are liabilities of the individual
equity members, and the amounts thereof depend on their respective income tax
situations.
 
    Capital accounts included in the accompanying financial statements differ
from amounts in the Company's federal income tax return primarily because of
differences in accounting policies adopted for financial and tax reporting
purposes.
 
    The tax returns, the qualification of the Company as a partnership for tax
purposes and the amount of distributable partnership income or loss are subject
to examination by federal taxing authorities. If such examinations result in
changes with respect to the partnership qualification or in changes to
distributable partnership income or loss, the tax liability of the partners
could be changed accordingly.
 
3. RELATED-PARTY TRANSACTIONS:
 
    The Company paid the Group A Members $50,000 in connection with assistance
in obtaining $20,000,000 of members' equity and other legal, financial and
administrative matters. As of December 31, 1997, no agreement exists between the
Company and Group A for Group A to provide any additional services; however, the
Company intends to enter into such an agreement with Group A to provide similar
services in 1998.
 
4. RIGS UNDER CONSTRUCTION AND EQUIPMENT:

5. COMMITMENTS AND CONTINGENCIES:
 
    The Company has entered into agreements with a shipyard and various
equipment vendors for delivery of two mobile offshore drilling rigs, the Chiles
Columbus and Chiles Magellan, for a total estimated cost of approximately $175
million. At December 31, 1997, the Company had purchase commitments of
approximately $128 million with respect to these rigs and equipment. These
amounts will become payable in future periods in accordance with terms of the
construction contract and vendor agreements, and management is currently
negotiating to obtain additional financing to meet these terms. The Chiles
Columbus is scheduled for delivery during the second quarter of 1999, and Chiles
Magellan is scheduled for delivery during the third quarter of 1999.

    As of December 31, 1997, the Company has no commitments to provide any
executives with severance benefits; however, the Company expects to enter into
an employment contract with one of its executives in 1998.
 
6. MEMBERS' EQUITY:
 
ALLOCATION OF NET INCOME OR LOSS
 
    In accordance with the Operating Agreement and the Agreement (collectively
referred to herein as the Agreements), profits or losses for any taxable year
were allocated in proportion to percentage interests, on a monthly basis and
after giving effect to special allocations set forth in the Agreements.
 
    The special allocations primarily result from the effect of U.S. federal
income tax rules for certain types of events that may occur to the Company. If
there is a Minimum Gain or Member Nonrecourse Debt Minimum Gain, as defined in
the IRS code, then the Agreements provide specific allocations to members in
order to comply with the IRS regulations. The Agreements provide that in the
event a member unexpectedly receives any adjustments, allocations or
distributions resulting from the special allocation rules of IRS regulations as
noted in the Agreements, then Company income and losses shall be specifically
allocated to such member, in an amount and manner sufficient to eliminate, to
the extent provided by the IRS regulations, the adjusted capital account deficit
of the member. The Agreements provide that, in the event any member has a
deficit capital account at the end of any taxable year, which is in excess of
the sum of the amount such member is obligated to restore pursuant to any
provision of the Agreements and the amount such member is obligated to restore
pursuant to the IRS code sections noted in the Agreements, each such member
shall be specially allocated items of the Company income and gain in the amount
of such excess as quickly as possible and to the extent allowed in the
Agreements. The Agreements provide that Nonrecourse Deductions, as defined in
the Agreements, for any taxable year shall be specially allocated to the members
in proportion to their respective percentage interests and that any member
Nonrecourse Deductions for any taxable year shall be specially allocated to the
member who bears the economic loss with respect to the member nonrecourse debt
to which such member Nonrecourse Deductions are attributable in accordance with
the regulations. In the event some, but not all, of the members would have
adjusted capital account deficits as a consequence of the special allocation
rules, then losses not allocable to any member due to such limitation shall be
allocated to other members pro rata in accordance with the balance of such
members' capital accounts.

DISTRIBUTIONS
 
    The Agreements provide for quarterly cash distribution of Net Cash Flow, as
defined in the Agreements, to members in proportion to, and to the extent of,
their relative percentage interests, an amount not in excess of the Tax
Distribution, as defined in the Agreements, for the taxable year, and upon the
approval by the Management Committee, as defined in the Agreements.
 
7. SUBSEQUENT EVENTS (UNAUDITED)
 
MANAGEMENT AGREEMENT
 
    The Company and Group A entered into a Management and Administrative
Services Agreement, dated as of February 27, 1998 (the Services Agreement),
pursuant to which Group A agreed to continue to perform certain administrative
and technical services on behalf of the Company. Such services include general
management and financial services, including periodic advice and consultation in
connection with corporate, legal, finance, accounting, tax, marketing,
operations and other matters that may be required for the Company's day-to-day
operations. Under the Services Agreement, the Company agreed to pay a fee to
Group A not to exceed $15,000 per month and such other fees for services of
others not to exceed the reasonable value thereof and to reimburse Group A for
all out-of-pocket expenses related to the provision of such services. The
Services Agreement may be terminated at either party's option upon 60 days'
notice to the other party.
 
OPTIONS PLAN
 
    Subsequent to year-end, the Company adopted the Chiles Offshore LLC 1998
Equity Option Plan (the Option Plan). The Option Plan authorizes the issuance of
Options to acquire up to 5.0% of the then outstanding membership interests on a
fully diluted basis. As of March 31, 1998, 3,953 units have been issued under
the Option Plan with an exercise price per unit of $650, which the Management
Committee believes approximates the fair market value per unit on the date of
grant based on recent transactions.
 
DEBT OFFERING
 
    In April, 1998, the Company formed three wholly owned subsidiaries, Chiles
Magellan LLC, Chiles Columbus LLC and Chiles Offshore Finance Corp. The Company
and Chiles Offshore Finance Corp. (Issuers) co-issued Senior Notes with a
principal amount of $110 million (Notes) on April 29, 1998. Prior to the
issuance of the Notes, the Company's three wholly owned subsidiaries were
nominally capitalized. The rig construction contracts, formerly owned by Chiles
Offshore LLC, for the Chiles Magellan and Chiles Columbus have been assigned to
Chiles Magellan LLC and Chiles Columbus LLC (Rig Owners), respectively.
 
    As a result, the Issuers received net proceeds of approximately $106.3
million after deducting estimated offering-related expenses. The Notes bear an
interest rate of 10%, payable semiannually on May 1 and November 1, commencing
on November 1, 1998 and mature in full in the year 2008. The net proceeds of the
Notes have been placed in escrow for use to partially fund the construction of
the two rigs and pay the first two semi-annual interest installments. The Notes
are redeemable in May, 2003, except that until May, 2001, up to 35% of the notes
may be redeemable with the proceeds of a public equity offering, both at the
option of the Issuers. The Notes are guaranteed by the Rig Owners, jointly and

severally, on an unsecured basis. Debt issuance costs related to the Notes are
being deferred and will be amortized over the life of the Notes.
 
BANK FACILITY
 
    The Company has entered into an agreement with two banks to provide a
revolving credit facility up to $25 million. The facility will be available to
the Company upon delivery of the first of the the two rigs. The facility will
bear interest at the rate of LIBOR plus 1.25% and matures on December 31, 2004,
at which time the outstanding principal amount will be due. The facility is
guaranteed by the Rig Owners.
 
EMPLOYMENT AGREEMENT
 
    The Company has entered into an employment agreement with its President for
a three year period. The Agreement provides, among other things, the amount of
compensation and other benefits to be provided to the President as well as other
conditions of the employment term.
 
EMPLOYEE 401(K) AND PROFIT SHARING PLAN
 
    Effective May 1, 1998, the Company adopted a 401(k) Profit Sharing Plan
(Plan), covering substantially all of its employees. The Company will match
employees' contributions to the Plan in an amount equal to 50%, up to 6% of
eligible compensation.
 
NEWLY ISSUED ACCOUNTING STANDARD
 
    In June 1997, Statement of Financial Accounting Standards No. 130, REPORTING
COMPREHENSIVE INCOME ("SFAS 130") was issued. SFAS 130 establishes standards for
reporting and display of comprehensive income and its components in a full set
of general purpose financial statements. Comprehensive income is the total of
net income and all other non-owner changes in equity. The Company has no
non-owner changes in equity during the three months ended March 31, 1998 and
therefore, no reporting and display of comprehensive income was required.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Chiles Offshore LLC and both of the Owners are Delaware limited liability
companies.
 
    Section 18-108 of the Delaware Limited Liability Company Act (the "Delaware
Act") grants a Delaware limited liability company the power, subject to such
standards and restrictions, if any, as are set forth in its limited liability
company agreement, to indemnify and hold harmless any member or manager or other
person from and against any and all claims and demands whatsoever. The Company's
Amended and Restated Operating Agreement, as amended, provides that the Company
will indemnify its Members, members of the Management Committee and the officers
of the Company, and certain other persons, from liabilities arising in the
course of such persons' service to the Company, provided that (i) the indemnitee
acted in good faith and in a manner which such indemnitee believed to be in or
not opposed to the interests of the Company and, with respect to any criminal
proceeding, had no reasonable cause to believe such indemnitee's conduct was
unlawful and (ii) the indemnitee's conduct did not constitute actual fraud,
gross negligence or willful or wanton misconduct. Such liabilities include all
losses, claims, demands, costs, damages, liabilities, expenses of any nature
(including reasonable attorneys' fees and disbursements), judgments, fines,
settlements and other amounts arising from any and all claims, demands, actions,
suits or proceedings, whether civil, criminal, administrative or investigative,
in which an indemnitee may be involved, or threatened to be involved, as a party
or otherwise, arising out of or incidental to the business of the Company,
including, without limitation, liabilities under the Federal and state
securities laws. The limited liability company agreements of the Owners provide
that, except as otherwise provided by the Delaware Act, the debts, obligations
and liabilities of the Owners, whether arising in contract, tort or otherwise,
shall be the debts, obligations and liabilities solely of the respective Owner,
and the Company, as sole member, shall not be obligated personally for any of
such debts, obligations or liabilities solely by reason of being a member.
 
    Finance is a Delaware corporation.
 
    Section 102 of the Delaware General Corporation Law ("DGCL") allows a
corporation to eliminate the personal liability of directors of a corporation to
the corporation or to its stockholders for monetary damages for a breach of his
fiduciary duty as a director, except in the case where the director breached his
duty of loyalty, failed to act in good faith, engaged in intentional misconduct
or knowingly violated a law, authorized the payment of a dividend or approved a
stock repurchase in violation of the DGCL or obtained an improper personal
benefit. Finance's Certificate of Incorporation contains a provision which, in
substance, eliminates directors' personal liability as set forth above.
 
    Section 145 of the DGCL allows a corporation to indemnify any person who was
or is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation), by
reason of the fact that he is or was a director or officer of the corporation,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. Finance's Certificate of
Incorporation contains a provision which, in substance, provides for
indemnification as set forth above to the fullest extent and in the manner set
forth in and permitted by the DGCL, and any other applicable law, as from time
to time in effect.
 
    Under Section 12.10 of the Indenture, the Holders of the Notes have agreed
to waive all liability for any obligations incurred by the Issuers under the
Notes or the Indenture or for any claim based on, in respect of or by reason of
such obligations or their creation, against any incorporator, director, officer,
 
                                      II-1
<PAGE>
employee, stockholder or controlling person, as such, of the Issuers or any
successor person thereof, and have agreed to the release of such persons from
any such liability.
 
    Under Section 5 of the Registration Rights Agreement, the Holders of the
Notes have agreed, severally and not jointly, to indemnify and hold harmless the
Issuers and controlling persons (within the meaning of the Securities Act and
the Exchange Act) of the Issuers from and against any losses, claims, damages or
liabilities, or any actions in respect thereof, to which the Issuers or any such
controlling person may become subject under the Securities Act, the Exchange Act
or otherwise, arising out of or based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in any exchange offer registration
statement or shelf registration statement for the Notes or any prospectus
forming part thereof or in any amendment or supplement thereto or (ii) the
omission or alleged omission to state therein a material fact necessary to make
the statements therein not misleading, in each case to the extent that such
untrue statement or omission or alleged untrue statement or omission was made in
reliance upon and in conformity with written information provided by such
Holders for inclusion therein.
 
    The Company does not currently maintain directors and officers liability
insurance, although it may consider obtaining such insurance upon commencement
of operation of one or both of the Rigs.

ITEM 22.  UNDERTAKINGS.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the
co-registrants have been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the co-registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

<PAGE>



          (i)  any Person that is not an Affiliate or Immediate Family Member
of a Member, as the case may be, with the approval of the Management
Committee; or

          (ii) any Person that is a Member or is an Affiliate of a Member or

shall also include their approval of any related valuations of Gross Asset
Value by the Management Committee and, if such Members approve the Transfer
without approving said valuation, Gross Asset Value shall be determined by a
third Person familiar with the valuation of such transactions selected jointly
by the Management Committee and a Majority in Interest of the Unaffiliated

such loans are made.

     (b)  A Member may (but shall not be obligated to) guarantee a loan made
to the Company.  If a Member guarantees a loan made to the Company and is
required to make payment pursuant to such guarantee to the maker of the loan,

by such Member to the Company and not as an additional capital contribution.

     3.4  Maintenance of Capital Accounts.

     are secured by any Property distributed to such Member.  The principal
     amount of a promissory note which is not readily traded on an established
     securities market and which is contributed to the Company by the maker of
     the note (or a Member related to the maker of the note within the meaning
     of Regulation Section 1.704-1(b)(2)(ii)(c)) shall not be included in the
     Capital Account of any Member until the Company makes a taxable
     disposition of the note or until (and only to the extent) principal
     payments are made on the note, all in accordance with Regulation Section
     1.704-1(b)(2)(iv)(d)(2);

          (ii) To each Member's Capital Account there shall be debited (A) the

                                      14
<PAGE>


     provision of this Agreement (including without limitation any
     distributions pursuant to Section 4.1(a)), (B) such Member's distributive
     share of Losses and any items in the nature of expenses or losses which
     are specially allocated pursuant to Section 5.3 or Section 5.4 hereof,
     and (C) the amount of any liabilities of such Member assumed by the
     Company or which are secured by any Property contributed by such Member
     to the Company;

     Transferred Membership Interests; and

          (iv) In determining the amount of any liability for purposes of
     Sections 3.4(a)(i) and 3.4(a)(ii) there shall be taken into account Code
     Section 752(c) and any other applicable provisions of the Code and
     Regulations.

     (b)  The foregoing Section 3.4(a) and the other provisions of this
Agreement relating to the maintenance of Capital Accounts are intended to
comply with Regulation Section 1.704-1(b) and, to the greatest extent
practicable, shall be interpreted and applied in a manner consistent with such
Regulation.  The Management Committee in its discretion and to the extent
otherwise consistent with this Agreement shall (i) make any adjustments that
are necessary or appropriate to maintain equality between the Capital Accounts
of the Members and the amount of capital reflected on the Company's balance
sheet, as computed for book purposes, in accordance with Regulation Section
1.704-1(b)(2)(iv)(q), and (ii) make any appropriate modifications in the event
unanticipated events might otherwise cause this Agreement not to comply with
Regulation Section 1.704-1(b).

expressly provided in this Agreement, no Member shall be entitled (a) to
withdraw or reduce such Member's Capital Contribution or to receive any

                                   ARTICLE 5
                                  ALLOCATIONS

     5.1  Profits.  After giving effect to the special allocations set forth
in Sections 5.3 and 5.4 hereof and subject to Section 5.7 hereof, Profits for
any Taxable Year shall be allocated to the Members in proportion to their
Percentage Interests.

     5.2  Losses.  After giving effect to the special allocations set forth in
Sections 5.3 and 5.4, subject to the limitation in Section 5.5 hereof and
subject to Section 5.7 hereof, Losses for any Taxable Year shall be allocated
to the Members in proportion to their Percentage Interests.

     5.3  Special Allocations.  The following special allocations shall be
made in the following order:

          (a)  Minimum Gain Chargeback.  Except as otherwise provided in
     Section 1.704-2(f) of the Regulations, notwithstanding any other
     provision of this Article 5, if there is a net decrease in Company
     Minimum Gain during any Taxable Year, each Member shall be specially
     allocated items of Company income and gain for such year (and, if
     necessary for subsequent years) in proportion to, and to the extent of,
     an amount equal to each Member's share of the net decrease in Company
     Minimum Gain during such taxable year as determined in accordance with
     the provisions of Regulation Section 1.704-2(g).  Allocations pursuant to
     the previous sentence shall be made in proportion to the respective
     amounts required to be allocated to each Member pursuant thereto.  The
     items to be so allocated shall be determined in accordance with Sections
     1.704-2(f) (6) and 1.704-2(j) (2) of the Regulations.  This Section
     5.3(a) is intended to comply with the minimum gain chargeback requirement
     in Section 1.704-2(f) of the Regulations and shall be interpreted
     consistently therewith.

          (b)  Member Minimum Gain Chargeback.  Except as otherwise provided
     in Section 1.704-2(i) (4) of the Regulations, notwithstanding any other
     provision of


                                      19
<PAGE>


     this Section 5, if there is a net decrease in Member Nonrecourse Debt
     Minimum Gain attributable to a Member Nonrecourse Debt during any Taxable
     Year, each Member who has a share of the Member Nonrecourse Debt Minimum
     Gain attributable to such Member Nonrecourse Debt, determined in
     accordance with Section 1.704-2(i) (5) of the Regulations, shall be
     specially allocated items of Company income and gain for such Taxable
     Year (and, if necessary, subsequent Taxable Years) in an amount equal to
     such Member's share of the net decrease in Member Nonrecourse Debt,
     determined in accordance with Regulation Section 1.704-2(i) (4).
     Allocations pursuant to the previous sentence shall be made in proportion
     to the respective amounts required to be allocated to each Member
     pursuant thereto.  The items to be so allocated shall be determined in
     accordance with Sections 1.704-2(i) (4) and 1.704-2(j) (2) of the
     Regulations.  This Section 5.3(b) is intended to comply with the minimum
     gain chargeback requirement in Section 1.704-2(i) (4) of the Regulations
     and shall be interpreted consistently therewith.

          (c)  Qualified Income Offset.  In the event any Member unexpectedly
     receives any adjustments, allocations, or distributions described in
     Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or
     1.704-1(b)(2)(ii)(d)(6) of the Regulations, items of Company income and
     gain shall be specially allocated to such Member in an amount and manner
     sufficient to eliminate, to the extent required by the Regulations, the
     Adjusted Capital Account Deficit of the Member as quickly as possible,
     provided that an allocation pursuant to this Section 5.3(c) shall be made
     only if and to the extent that the Member would have an Adjusted Capital
     Account Deficit after all other allocations provided for in this Section
     5 have been tentatively made.

          (d)  Gross Income Allocation.  In the event any Member has a deficit
     Capital Account at the end of any Taxable Year which is in excess of the
     sum of (i) the amount such Member is obligated to restore pursuant to any
     provision of this Agreement and (ii) the amount such Member is obligated
     to restore pursuant to the penultimate sentences of Regulations Sections
     1.704-2(g)(1) and 1.704-2(i)(5), each such Member shall be specially
     allocated items of Company income and gain in the amount of such excess
     as quickly as possible; provided, however, that an allocation pursuant to
     this


                                      20
<PAGE>


     Section 5.3(d) shall be made only if and to the extent that such Member
     would have a deficit Capital Account in excess of such sum after all
     other allocations provided for in this Section 5 have been made other
     than those allocations pursuant to Section 5.3(c) and this Section
     5.3(d).

          (e)  Nonrecourse Deductions.  Nonrecourse Deductions for any Taxable
     Year shall be specially allocated to the Members in proportion to their
     respective Percentage Interests.

          (f)  Member Nonrecourse Deductions.  Any Member Nonrecourse
     Deductions for any Taxable Year shall be specially allocated to the
     Member who bears the economic risk of loss with respect to the Member
     Nonrecourse Debt to which such Member Nonrecourse Deductions are
     attributable in accordance with Regulation Section 1.704-2(i) (1).

     5.4  Curative Allocations.  The allocations set forth in Sections 5.3(a),
5.3(b), 5.3(c), 5.3(d), 5.3(e), 5.3(f) and 5.5 (the "Regulatory Allocations")
are intended to comply with certain requirements of the Regulations.  It is
the intent of the Members that, to the extent possible, all Regulatory
Allocations shall be offset either with other Regulatory Allocations or with
special allocations of other items of Company income, gain, loss or deduction
pursuant to this Section 5.4.  Therefore, notwithstanding any other provision
of this Section 5 (other than the Regulatory Allocations), following any
Regulatory Allocation, the Management Committee shall use its best efforts to
make such offsetting special allocations of Company income, gain, loss or
deduction in whatever reasonable manner it determines so that, after such
offsetting allocations are made, each Member's Capital Account balance is, to
the extent possible, equal to the Capital Account balance such Member would
have had if the Regulatory Allocations had not been made and all Company items
were allocated pursuant to Sections 5.1 and 5.2.

     5.5  Loss Limitation.  Losses allocated pursuant to Section 5.2 hereof
shall not exceed the maximum amount of Losses that can be allocated without
causing any Member to have an Adjusted Capital Account Deficit at the end of
any Taxable Year.  In the event some but not all the Members would have
Adjusted Capital Account Deficits as a consequence of an allocation of Losses
pursuant to Section 5.2 hereof, the limitation set forth in this Section 5.5


                                      21
<PAGE>


shall be applied on a Member by Member basis and Losses not allocable to any
Member as a result of such limitation shall be allocated to the other Members
pro rata in accordance with the positive balances in such Members' Capital
Accounts so as to allocate the maximum permissible Losses to each Member under
Section 1.704-1(b)(2)(ii)(d) of the Regulations.

     5.6  Tax Allocations:  Code Section 704(c).

     (a)  In accordance with Code Section 704(c) and the Regulations
thereunder, income, gain, loss and deduction with respect to any Property
contributed to the capital of the Company shall, solely for tax purposes, be
allocated among the Members so as to take account of any variation between the
adjusted basis of such Property to the Company for federal income tax purposes
and its initial Gross Asset Value (computed in accordance with the definition
of Gross Asset Value).

     (b)  In the event the Gross Asset Value of any Company asset is adjusted
pursuant to subparagraph (b) of the definition of Gross Asset Value,
subsequent allocations of income, gain, loss and deduction with respect to
such asset shall take account of any variation between the adjusted basis of
such asset for federal income tax purposes and its Gross Asset Value in the
same manner as under Code Section 704(c) and the Regulations thereunder.

     (c)  Any elections or other decisions relating to such allocations shall
be made by the Management Committee in any manner that reasonably reflects the
purpose and intention of this Agreement; provided, that the Company, in the
discretion of the Management Committee, may make, or not make, "curative" or
"remedial" allocations (within the meaning of the Regulations under Code
Section 704(c)) including, but not limited to, "curative" allocations which
offset the effect of the "ceiling rule" for a prior Taxable Year (within the
meaning of Regulation Section 1.704-3(c)(3)(ii) and "curative" allocations
from disposition of contributed property (within the meaning of Regulation
Section 1.704-3(c)(3)(iii)(B).  Allocations pursuant to this Section 5.6 are
solely for purposes of federal, state, and local taxes and shall not affect,
or in any way be taken into account in computing, any Member's Capital Account
or share of Profits, Losses, other items, or distributions (other than Tax
Distributions) pursuant to any provision of this Agreement.


                                      22
<PAGE>


     5.7  Change in Percentage Interests.  In the event that the Members'
Percentage Interests change during a Taxable Year, Profits and Losses shall be
allocated taking into account the Members' varying Percentage Interests for
such Taxable Year, determined on a daily, monthly or other basis as determined
by the Management Committee, using any permissible method under Code Section
706 and the Regulations thereunder.


     5.8  Withholding.  Each Member hereby authorizes the Company to withhold
and to pay over any taxes payable by the Company or any of its Affiliates as a
result of such Member's participation in the Company; if and to the extent
that the Company shall be required to withhold any such taxes, such Member
shall be deemed for all purposes of this Agreement to have received a payment
from the Membership as of the time such withholding is required to be paid,
which payment shall be deemed to be a distribution to such Member to the
extent that the Member is then entitled to receive a distribution.  To the
extent that the aggregate of such payments in respect of a Member for any
period exceeds the distributions to which such Member is entitled for such
period, the amount of such excess shall be considered a demand loan from the
Company to such Member, with interest at 8% per annum, which interest shall be
treated as an item of Company income, until discharged by such Member by
repayment, which may be made in the sole discretion of the Management
Committee out of distributions to which such Member would otherwise be
subsequently entitled.  The withholdings referred to in this Section 5.8 shall
be made at the maximum applicable statutory rate under the applicable tax law
unless the Management Committee shall have received an opinion of counsel or
other evidence, satisfactory to the Management Committee, to the effect that a
lower rate is applicable, or that no withholding is applicable.

     (a)  The Company shall indemnify and hold harmless each Manager and
Member and their respective Affiliates and all officers, directors, members,
partners, stockholders, managers and employees thereof, and each officer of
the Company and any Person serving in any similar capacity for another Person
affiliated with the Company at the request of the Company (solely for purposes
of this Section 8.2, each such Person being referred to as, a "Company
Affiliate"), from and against any and all losses, claims, demands, costs,
damages, liabilities, expenses of any nature (including reasonable attorneys'
fees and disbursements), judgments, fines, settlements and other amounts
arising from any and all claims, demands, actions, suits or proceedings,
whether civil, criminal, administrative or investigative, in which a Company
Affiliate may be involved, or threatened to be involved, as a party or
otherwise, arising out of or incidental to the business of the Company,
including, without limitation, liabilities under the Federal and state
securities laws, regardless of whether a Company Affiliate continues to be a
Company Affiliate, at the time any such liability or expense is paid or
incurred, if (i) the Company Affiliate acted in good faith and in a manner it
or he reasonably believed to be in, or not opposed to, the interests of the
Company and, with respect to any criminal proceeding, had no reason to believe
its or his conduct was unlawful, and (ii) the Company Affiliate's conduct did
not constitute actual fraud, gross negligence or willful or wanton misconduct.
The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere, or its equivalent,
shall not, in and of itself, create a presumption or otherwise constitute
evidence that the Company Affiliate acted in a manner contrary to that
specified in (i) or (ii) above.

     (b)  Expenses (including reasonable legal fees and expenses) incurred in
defending any proceeding subject to subsection (a) of this Section 8.2 shall
be paid by the Company in advance of the final disposition of such


                                      29
<PAGE>


proceeding upon receipt of a written affirmation by the Company Affiliate of
his or its good faith belief that he or it has met the standard of conduct
necessary for indemnification under this Section 8.2 and a written undertaking
(which need not be secured) by or on behalf of the Company Affiliate to repay
such amount if it shall ultimately be determined, by a court of competent
jurisdiction or otherwise, that the Company Affiliate is not entitled to be
indemnified by the Company as authorized hereunder.

     (c)  The indemnification provided by this Section 8.2 shall be in
addition to any other rights to which each Company Affiliate may be entitled
under any agreement or vote of the Management Committee by the vote of
Managers that are disinterested and unaffiliated with such Company Affiliate,
as a matter of law or otherwise, both as to action in the Company Affiliate's
capacity as a Company Affiliate or as a Person serving at the request of the
Company and shall continue as to a Company Affiliate who has ceased to serve
in such capacity and shall inure to the benefit of the heirs, successors,
assigns, administrators and personal representatives of such Company
Affiliate.

     (d)  The Company may purchase and maintain directors and officers
insurance or, similar coverage, for its Managers and its officers in such
amounts and with such deductibles or self-insured retentions as are customary
for Persons engaged in businesses similar in size and type to those engaged in
by the Company.

     (e)  Except as provided in Section 3.4, any indemnification hereunder
shall be satisfied only out of the assets of the Company and the Members shall
not be subject to personal liability by reason of these indemnification
provisions.  To the extent the Company does not have adequate cash available
to satisfy its obligations under this Article 8, the Company shall pay its
obligations under this Article 8 out of Net Cash Flow prior to making any
distributions (other than distributions under Section 4.1(a) hereof) to the
Members.

     (f)  A Company Affiliate shall not be denied indemnification in whole or
in part under this Section 8.2 because the Company Affiliate had an interest
in the transaction with respect to which the indemnification applies if the
transaction was otherwise permitted by the terms of this Agreement and all
material facts relating to such indemnitee's interest were adequately
disclosed to the


                                      30
<PAGE>


Management Committee at the time the transaction was consummated.

     (g)  The provisions of this Section 8.2 are for the benefit of the
Company Affiliates and the heirs, successors, assigns, administrators and
personal representatives of the Company Affiliates and shall not be deemed to
create any rights for the benefit of any other Persons.

     (h)  Any repeal or amendment of any provisions of this Section 8.2 shall
be prospective only and shall not adversely affect any Company Affiliates's
right existing at the time of such repeal or amendment.

                                   ARTICLE 9
                       TRANSFERS OF MEMBERSHIP INTERESTS

     9.1  General Restrictions.

     (a)  No Member may Transfer all or any part of such Member's Membership
Interest, except as provided in this Agreement.  Any purported Transfer or
purported purchase of a Membership Interest or a portion thereof in violation
of the terms of this Agreement shall be null and void and of no effect.  A
permitted Transfer shall be effective as of the date specified in the
instruments relating thereto.  Any transferee desiring to make a further
Transfer shall become subject to all the provisions of this Article 9 to the
same extent and in the same manner as any Member desiring to make any
Transfer.  No Member shall have the right to withdraw as a Member of the
Company.

     (b)  In the event that the Membership Interests (or securities issued in
exchange for Membership Interests upon conversion of the Company into a
corporation) are registered under the Securities Act, the Transfer
restrictions set forth in this Article 9 shall terminate.

     9.2  Permitted Transferees.

     (a)  Notwithstanding the provisions of Section 9.8 and 9.9, each Member
that is a natural person shall have the right to Transfer (but not to
substitute the transferee as a substitute Member in such Member's place,
except in accordance with Section 9.3), by a written instrument, all or any
part of such Member's Membership Interest, to an Immediate Family Member; it
being understood that any such Permitted Transferee shall be deemed to be an
additional or substitute Member as of the date of such Transfer and each
Member agrees to take such action and execute such documents as such
transferee may deem reasonably necessary and appropriate for such transferee
to become a substitute or additional Member.

     (b)  Notwithstanding the provisions of Sections 9.8 and 9.9, each Member
that is not a natural Person (other than COI) shall have the right to Transfer
(but not to substitute the transferee as a substitute Member in such Member's
place, except in accordance with Section 9.3), by a written instrument, all or
any part of a Member's Membership Interest, to any of its Affiliates; it being
understood that any such Permitted Transferee shall be deemed to be an
additional or substitute Member as of the date of such Transfer and each
Member agrees to take such action and execute such documents as such
transferee may deem reasonably necessary and appropriate for such transferee
to become a substitute or additional Member.

     (c)  Notwithstanding the provisions of Sections 9.8 and 9.9, COI shall
have the right to Transfer (but not to substitute the transferee as a
substitute Member in COI's place, except in accordance with Section 9.3), by a
written instrument, all of its Membership Interest, to its members pro rata in
accordance with their percentages of membership interests set forth on
Schedule 2; it being understood that each such Permitted Transferee shall be
deemed an additional or substitute Member as of the date of such Transfer and
each Member agrees to take such action and execute such documents as such
transferee may deem reasonably necessary and appropriate for such transferee
to become a substitute or additional Member.

     (d)  Notwithstanding the provisions of Sections 9.8 and 9.9, a Member
shall have the right to pledge such Member's Membership Interest, in whole or
in part, to a financial institution as collateral security for a loan to such
Member by such financial institution so long as the Management


                                      32
<PAGE>


Committee has given its prior written consent to said pledge, which consent
shall not be unreasonably withheld; provided, however, that no such pledge
shall be made for the purpose of effecting a disguised sale to the pledgee
and; provided further, that any such pledgee or a transferee of such pledgee,
as appropriate, shall agree in a writing delivered to the Company to be bound
by all of the terms and conditions of this Agreement.

     (e)  Unless and until admitted as a substitute Member pursuant to
Section 9.3, a transferee of a Member's Membership Interest in whole or in
part shall be an assignee with respect to such Transferred Membership Interest
and shall not be entitled to participate in the management of the business and
affairs of the Company or to become or to exercise the rights of a Member,
including the right to vote, the right to require any information or
accounting of the Company's business or the right to inspect the Company's
books and records.  Such transferee shall only be entitled to receive, to the
extent of the Membership Interest transferred to such transferee, the share of
distributions and profits, including distributions representing the return of
Capital Contributions, to which the transferor would otherwise be entitled
with respect to the Transferred Interest.  The transferror shall have the
right to vote such Transferred Interest until the transferee is admitted to
the Company as a substituted Member with respect to the Transferred Interest.

     9.3  Substitute Members.  No transferee of all or part of a Member's
Membership Interest shall become a substitute Member in place of the
transferor unless and until:

          (a)  the transferee has executed an instrument in form and substance
     reasonably satisfactory to the Management Committee accepting and
     adopting the terms and provisions of the Certificate and this Agreement;
     and

          (b)  the transferee has caused to be paid all reasonable expenses of
     the Company in connection with the admission of the transferee as a
     substitute Member.

     Upon satisfaction of all the foregoing conditions with respect to a
particular transferee, the President and Chief Executive Officer shall cause
the books and records of the Company to reflect the admission of the
transferee as a substitute Member to the extent of the Transferred Interest
held by the transferee.


                                      33
<PAGE>


     9.4  Effect of Admission as a Substitute Member.  A transferee who has
become a substitute Member has, to the extent of the transferred Membership
Interest, all the rights, powers and benefits of, and is subject to the
restrictions and liabilities of a Member under the Certificate, this Agreement
and the Act.  Upon admission of a transferee as a substitute Member, the
transferor of the Membership Interest so held by the substitute Member shall
cease to be a Member of the Company to the extent of such transferred
Membership Interest.

     9.5  Consent.  Each Member hereby agrees that upon satisfaction of the
terms and conditions of this Article 9 with respect to any proposed Transfer,
the Person proposed to be such transferee may be admitted as a Member.

     9.6  No Dissolution.  If a Member transfers all of its Membership
Interest pursuant to this Article 9 and the transferee of such Membership
Interest is admitted as a Member pursuant to Section 9.3, such Person shall be
admitted to the Company as a Member effective on the effective date of the
Transfer or such other date as may be specified when the Member is admitted.
In such event, the Company shall not dissolve if the business of the Company
is continued without dissolution in accordance with clause (c) of Section 10.1
hereof.

     9.7  Additional Members; Certain Representations of Members.  Subject to
Section 3.6, from and after the date hereof, any Person acceptable to the
Management Committee may become an additional Member of the Company for such
consideration as the Management Committee shall determine, provided that such
additional Member complies with all the requirements of a transferee under
Sections 9.3(a) and (b).

     9.8  Right of First Offer.

     (a) If at any time any Member (hereinafter for purposes of this Section
9.8, the "Section 9.8 Selling Members") proposes to Transfer to any Person
other than a Permitted Transferee (hereinafter for purposes of this Section
9.8, the "Section 9.8 Proposed Purchaser") its Membership Interest (or any
portion thereof), such Section 9.8 Selling Member shall provide Notice of the
proposed Transfer to the other Members (hereinafter for purposes of Section
9.8, the "Section 9.8 Offerees") setting forth the price, terms and conditions
of the proposed sale of the Membership Interest.  Each of the Section 9.8
Offerees shall have the option to acquire such Member's pro rata portion
(which shall be in


                                      34
<PAGE>


proportion to the Percentage Interests of all Section 9.8 Offerees) at the
time of such Notice on the terms and conditions set forth in such Notice.  The
option of Section 9.8 Offerees to purchase their pro rata portions of the
Membership Interest shall be exercised by delivery of a Notice to the Section
9.8 Selling Member and the Company of exercise within twenty (20) days
following receipt of the Section 9.8 Selling Member's Notice of the price,
terms and conditions of the sale.  A Section 9.8 Offeree may exercise such
Member's option to purchase such Membership Interest only as to the entire
portion thereof that such Member is entitled to purchase.  If any Section 9.8
Offeree fails or declines to purchase such Member's pro rata portion of such
Membership Interest, then such Member's portion of such Membership Interest
shall be offered to the Section 9.8 Offerees who have exercised their options
to purchase their pro rata portions.  This procedure shall continue until such
time as the entire Membership Interest offered hereby has been purchased by
such Section 9.8 Offerees or until no such Member desires to purchase any
additional Membership Interest hereunder.  Each Section 9.8 Offeree shall have
the right to offer to acquire such Membership Interest by delivering to the
Section 9.8 Selling Member and the Company such Member's Notice of acceptance
within five (5) Business Days following receipt of the Company's Notice that
additional portions are available.  If less than the entire Membership
Interest to be sold by the Section 9.8 Selling Member is to be purchased by
the Section 9.8 Offerees, the Section 9.8 Selling Member may sell the entire
Membership Interest to be sold within sixty (60) days from the Notice referred
in the preceding sentence, upon terms and conditions no less favorable to the
Section 9.8 Selling Member than were set forth in the initial Notice (it being
understood that such terms may include the receipt by the Selling Member of
consideration consisting of only cash and/or securities with a readily
ascertainable market value).

     (b) The sale of any Membership Interest to Section 9.8 Offerees who
exercise their options to purchase any Membership Interest shall occur twenty-
one (21) days after the expiration of the last option to expire under Section
9.8(a) above.  At the closing, each of the Section 9.8 Offerees shall deliver
a certified or bank cashier's check in, or wire transfer immediately available
funds in the appropriate amount to the Section 9.8 Selling Member against the
simultaneous delivery of an assignment in form and substance reasonably
satisfactory to each Section 9.8 Offeree of the Member Interest (or portion
thereof) being


                                      35
<PAGE>


transferred to such Section 9.8 Offeree, such assignment shall be made free
and clear of all liens, claims and encumbrances, except as provided by this
Agreement or as otherwise agreed to by such Section 9.8 Offeree; provided,
however, that each such Section 9.8 Selling Member shall not be required to
make any other representations or warranties in connection with such sale
except that it has the authority to sell its Membership Interest, is the sole
owner of such Membership Interest and has good and valid title to such
Membership Interest and that the sale of its Membership Interest does not
violate any agreement to which it is a party or by which it is bound.

     9.9   Tag-Along Rights. (a)  In the event of any proposed Transfer in any
one transaction or in a series of related transactions by any Member or
Members (hereinafter for purposes of this Section 9.9, collectively, the
"Section 9.9 Selling Member") of its or their Membership Interests
constituting in the aggregate twenty percent (20%) or more of all the
Membership Interests to any Person (such Person being hereinafter referred to
as the "Section 9.9 Proposed Purchaser"), other than to a Permitted Transferee
or in a bona fide public distribution pursuant to an effective Registration
Statement under the Securities Act, each of the other Members (hereinafter for
purposes of this Section 9.9, the "Section 9.9 Tagged Members") shall have the
irrevocable and exclusive right, but not the obligation (the "Tag-Along
Right"), to require the Section 9.9 Proposed Purchaser to purchase from each
of them such Section 9.9 Tagged Member's pro rata portion (i.e., such Tagged
Member's Percentage Interest) of the Membership Interests proposed to be sold
by the Section 9.9 Selling Members to the Section 9.9 Proposed Purchaser
(collectively, the "Section 9.9 Tag-Along Membership Interest").  The Section
9.9 Selling Members shall give Notice (the "Initial Tag-Along Notice") to the
Section 9.9 Tagged Members at least thirty (30) days prior to the date of the
proposed Transfer and at least three (3) Business Days after the expiration of
the last option to expire under Section 9.8(a) above, stating:

          (i) the name and address of the Section 9.9 Proposed Purchaser;

          (ii) the proposed amount of consideration and terms and conditions
     of payment offered by such Section 9.9 Proposed Purchaser (if the
     proposed consideration is not cash, the Notice shall describe the terms
     of the proposed consideration) and any other material terms and
     conditions of the Section 9.9 Proposed Purchaser's offer;


                                      36
<PAGE>


          (iii) the Membership Interest proposed to be transferred; and

          (iv) that the Section 9.9 Proposed Purchaser has been informed of
     the Tag-Along Right and has agreed to purchase Membership Interests in
     accordance with the terms hereof.

     The Tag-Along Right shall be exercised by any or all of the Section 9.9
Tagged Members by giving Notice to the Company ("Tag-Along Notice") with a
copy to each Section 9.9 Selling Member, within five (5) days following
receipt of the Initial Tag-Along Notice, indicating its election to exercise
the Tag-Along Right (hereinafter referred to for purposes of this Section 9.9,
the "Section 9.9 Participating Tagged Members").  The Tag-Along Notice shall
state the amount of Membership Interests that such Section 9.9 Participating
Tagged Member proposes to include in such transfer to the Section 9.9 Proposed
Purchaser.  Failure by any Section 9.9 Tagged Member to give such Tag-Along
Notice within such 5 day period shall be deemed an election by such Section
9.9 Tagged Member not to sell its Membership Interests pursuant to the Initial
Tag-Along Notice.  The closing with respect to any sale to a Section 9.9
Proposed Purchaser pursuant to this Section shall be held at the time and
place specified in the Initial Tag-Along Notice but in any event within sixty
(60) days of the date the Initial Tag-Along Notice is given.  Consummation of
the sale of Membership Interests by any Section 9.9 Selling Member to a
Section 9.9 Proposed Purchaser shall be conditioned upon consummation of the
sale by each Section 9.9 Participating Tagged Member to such Section 9.9
Proposed Purchaser of the Section 9.9 Tag-Along Membership Interest, if any.

     (b) In the event that the Section 9.9 Proposed Purchaser does not
purchase the Section 9.9 Tag-Along Membership Interest from the Section 9.9
Participating Tagged Members on the same terms and conditions as purchased
from the Section 9.9 Selling Member, then the Section 9.9 Selling Member
making such Transfer shall purchase on such terms and conditions such Section
9.9 Tag-Along Membership Interest if the Transfer occurs.

     (c) The Section 9.9 Selling Members who are parties to a sale to a
Section 9.9 Proposed Purchaser shall arrange for payment (by bank cashier's
check or certified check or by wire transfer of immediately available funds)
directly by the Section 9.9 Proposed Purchaser to each Section 9.9
Participating Tagged Member, upon delivery of an appropriate


                                      37
<PAGE>



assignment in form and substance reasonably satisfactory to the Section 9.9
Proposed Purchaser, which assignment shall be made free and clear of all
liens, claims and encumbrances except as provided by this Agreement or as
otherwise agreed to by such Section 9.9 Proposed Purchaser; provided, however,
that each such Section 9.9 Participating Tagged Member shall not be required
to make any other representations or warranties in connection with such sale
except that it has the authority to sell its Membership Interest, is the sole
owner of such Membership Interest and has good and valid title to such
Membership Interest and that the sale of its Membership Interest does not
violate any agreement to which it is a party or by which it is bound.

     (d) If at the end of 60 days following the date on which an Initial Tag-
Along Notice was given, the sale of Membership Interests by the Section 9.9
Selling Members and the sale of the Section 9.9 Tag-Along Membership Interests
have not been completed in accordance with the terms of the Section 9.9
Proposed Purchaser's offer, all the restrictions on sale, transfer or
assignment contained in this Agreement with respect to Membership Interests
owned by the Members shall again be in effect.

     9.10 Drag-Along Rights.

     (a)  In the event of any proposed Transfer of Membership Interest
constituting a majority of all Membership Interests by any Member or Members
(hereinafter for purposes of this Section 9.10, collectively a "Section 9.10
Selling Members") of all of its or their Membership Interest to a Person (such
Person being hereinafter referred to as the "Section 9.10 Proposed
Purchaser"), other than a Permitted Transferee or in a bona fide public
distribution pursuant to an effective Registration Statement under the
Securities Act, such Section 9.10 Selling Members shall have the right (the
"Drag-Along Right"), to require each other Member (hereinafter for purposes of
this Section 9.10, the "Section 9.10 Dragged Members") to Transfer to the
Section 9.10 Proposed Purchaser each such Section 9.10 Dragged Member's entire
Membership Interest (such Membership Interests as may be required to be so
Transferred being hereinafter referred to as the "Section 9.10 Drag-Along
Membership Interests").  The Section 9.10 Selling Members shall exercise their
Drag-Along Right by giving Notice (the "Drag-Along Notice") to each Section
9.10 Dragged Member at least twenty (20) days prior to the date of the
proposed Transfer and at least


                                      38
<PAGE>

under Section 9.8(a) above, stating:

          (i)  the name and address of the Section 9.10 Proposed Purchaser;

          (ii)  the proposed amount of consideration and terms and conditions
     of payment offered by such Section 9.10 Proposed Purchaser (if the
     proposed consideration is not cash, the notice shall describe the terms
     of the proposed consideration);

          (iii)  the Membership Interests proposed to be transferred; and

          (iv) that the Section 9.10 Proposed Purchaser has been informed of
     the Drag-Along Right and has agreed to purchase Membership Interests in
     accordance with the terms hereof.

     The closing with respect to any sale to a Section 9.10 Proposed Purchaser
pursuant to this Section shall be held at the time and place specified in the
Drag-Along Notice but in any event within sixty (60) days of the date the
Drag-Along Notice is given.  Consummation of the sale of Membership Interests
by any Member to a Section 9.10 Proposed Purchaser shall be conditioned upon
consummation of the sale by each Section 9.10 Selling Member to such Section
9.10 Proposed Purchaser of the Membership Interests proposed to be sold by the
Section 9.10 Selling Members.

     (b)  In the event that the Section 9.10 Proposed Purchaser does not
purchase the Section 9.10 Drag-Along Membership Interests from the Section
9.10 Dragged Members on the same terms and conditions as purchased from the
Section 9.10 Selling Members, then such Section 9.10 Dragged Members shall
have the right to require the Company to cause the Section 9.10 Selling
Members making such Transfer to purchase on such terms and conditions such
Section 9.10 Drag-Along Membership Interests if the Transfer occurs.

     (c)  The Section 9.10 Selling Members who are parties to a sale to a
Section 9.10 Proposed Purchaser shall arrange for payment directly by the
Section 9.10 Proposed Purchaser to each Section 9.10 Dragged Member, upon
delivery of the an appropriate assignment in form and substance reasonably
satisfactory to the Section 9.10 Proposed Purchaser, which assignment shall be
made free and clear of all liens, claims and encumbrances, except as provided
by this Agreement or as


                                      39
<PAGE>


otherwise agreed to by such Section 9.10 Proposed Purchaser; provided,
however, that each such Dragged Stockholder shall not be required to make any
other representations or warranties in connection with such sale except that
it has the authority to sell its Membership Interest, is the sole owner of
such Shares and has good and valid title to such Membership Interest, and that
the sale of such Membership Interest does not violate any agreement to which
it is a party or by which it is bound.

     (d)  If at the end of 60 days following the date on which a Drag-Along
Notice was given, the sale of Membership Interests by the Section 9.10 Selling
Members and the sale of the Section 9.10 Drag-Along Membership Interests have
not been completed in accordance with the terms of the Drag-Along Notice, all
the restrictions on sale, transfer or assignment contained in this Agreement
with respect to Membership Interests owned by the Section 9.10 Selling Members
shall again be in effect.

          (i)  "Common Stock" shall mean the common stock of the Company
     issued upon conversion of the Company to a corporation;

          (ii) "Other Shares" shall mean at any time those shares of Common
     Stock or other securities of the Company which do not constitute Primary
     Shares or Registrable Shares;

          (iii)     "Primary Shares" shall mean at any time authorized but
     unissued shares of Common Stock or shares of Common Stock held by the
     Company in its treasury;

          (iv) "Registrable Shares" shall mean the shares of Common Stock held
     by the Members in the Company which constitute Restricted Shares and
     which are not then eligible for sale to the public pursuant to Rule 144
     (other than Rule 144(k)) in a single transaction (and including
     Membership Interests held by Members prior to the conversion of the
     Company to a corporation).

          (v)  "Restricted Shares" shall mean any Membership Interests, shares
     of Common Stock or other securities




                                      40

<PAGE>



     received in respect thereof held or which may be acquired from the
     Company by the Members as of the applicable date, and which theretofore

register the Primary Shares or Other Shares and, upon the written request,
given within 30 days after delivery of any such Notice by the Company, of the
Members to include in such registration Registrable Shares (which request
shall specify the number of Registrable Shares proposed to be included in such
registration), the Company shall use its best efforts to cause all such
Registrable Shares to be included in such registration on the same terms and
conditions as the securities otherwise being sold in such registration;
provided, however, that if the managing underwriter advises the Company that
the inclusion of all Registrable Shares or Other Shares proposed to be
included in such registration would interfere with the successful marketing
(including pricing) of Primary Shares proposed to be registered by the
Company, then the number of Primary Shares, Registrable Shares and Other
Shares proposed to be included in such registration shall be included in the
following order:

          (i)  first, the Primary Shares; and

          (ii) second, the Registrable Shares and Other Shares requested to be
     included in such registration pro rata, based upon the respective numbers
     of Restricted Shares owned at the time by each Member and the respective

     (c)  If at any time after giving Notice pursuant to this Section 9.11 of

determination not to register, shall be relieved of its obligation to register
any Registrable Securities in connection with such registration and (ii) in
the case of a determination to delay registering, shall be permitted to delay
registering any Registerable Securities, for the same period as the delay in

     (d)  If a registration under this Section 9.11 involves an underwritten
offering, the underwriter or underwriters and any additional investment
bankers and managers to be used in connection with such registration shall be

                          DISSOLUTION AND TERMINATION

     10.1 Events Causing Dissolution.  The Company shall be dissolved and its
affairs wound up upon the first to occur of the following events:

          (a)  The vote to dissolve Members holding not less than ninety
     percent (90%) of the Membership Interests;

          (b)  The sale, Transfer or other disposition of substantially all of
     the assets of the Company and the receipt and distribution of all the
     proceeds therefrom;

          (c)  The death, retirement, resignation, insanity, expulsion,
     bankruptcy or dissolution of a Member, or any other event which
     terminates the continued membership of a Member in the Company, unless
     there is at least one remaining Member;

          (d)  The entry of a decree of judicial dissolution pursuant to
     Section 18-802 of the Act; or

          (e) The expiration of the term of the Company as provided in Section
     2.5.

     10.2 Notices to Secretary of State.  When all the remaining property and
assets of the Company have been distributed, the Certificate shall be
cancelled by filing a certificate of cancellation with the Secretary of State
of Delaware.

     10.3 Cash Distributions Upon Dissolution.  Upon the dissolution of the
Company as a result of the occurrence of any of the events set forth in
Section 10.1, the Management Committee shall proceed to wind up the affairs of
and liquidate the Company and any cash and proceeds therefrom shall be applied
and distributed in the following order of priority:

          (a)  First, to the payment (or the making of reasonable provision
     for payment) of debts and liabilities of the Company in the order of
     priority as provided by law (including any loans or advances that may
     have been made by any of the Members to the Company) and the expenses of


                                      43
<PAGE>


     liquidation including the establishment of any Reserves which the
     Management Committee may reasonably deem necessary for any contingent,
     conditional or unasserted claims or obligations of the Company.  Such
     Reserves may be paid over by the Company to an escrow agent to be held
     for disbursement in payment of any of the aforementioned liabilities and,
     at the expiration of such period as shall be reasonably deemed advisable
     by the Management Committee, for distribution of the balance in the
     manner provided in this Article 10;

          (b)  Finally, the remaining balance, if any, to the Members in
     proportion to their respective positive Capital Accounts, after giving
     effect to all contributions, distributions and allocations for all
     periods, in accordance with the requirements of Regulation Section
     1.704-1(b)(2)(ii)(b)(2).

     10.4 In-Kind.  Notwithstanding the foregoing but subject to Section 18-
804(a)(1) of the Act, in the event the Management Committee shall determine
that an immediate sale of part of or all the Property would cause undue loss
to the Members, or the Management Committee determines that it would be in the
best interest of the Members to distribute the Property to the Members in-kind
(which distributions do not, as to the in-kind portions, have to be in the
same proportions as they would be if cash were distributed, but all such in-
kind distributions shall be equalized, to the extent necessary, with cash),
then the Management Committee may either defer liquidation of, and withhold
from distribution for a reasonable time, any of the Property except that
necessary to satisfy the Company's debts and obligations, or distribute the
Property to the Members in-kind.

     10.5 No Action for Dissolution.  The Members acknowledge that irreparable
damage would be done to the goodwill and reputation of the Company if any
Member should bring an action in court to dissolve the Company under
circumstances where dissolution is not required by Section 10.1.  Accordingly,
except where the Managers have failed to liquidate the Company as required by
Section 10.1 and except as specifically provided in Section 18-802 and Section
18-803(a) of the Act, each Member hereby to the fullest extent permitted by
law waives and renounces his right to initiate legal action to seek
dissolution of the Company or


                                      44
<PAGE>


to seek the appointment of a receiver or trustee to wind up the affairs of the
Company, except in the cases of fraud, violation of law, bad faith, gross
negligence, willful misconduct or willful violation of this Agreement.

          (f)  to take any other action on behalf of the Members (with respect
     to the Company) or the Company in connection with any administrative or
     judicial tax proceeding to the extent permitted by applicable law or the
     Regulations.

     Each Member shall have the right to participate in any such actions and
proceedings to the extent provided for under the Code and Regulations.

     11.3 Indemnity of Tax Matters Member.  To the maximum extent permitted by
applicable law and without limiting Article 8, the Company shall indemnify and
reimburse the Tax Matters Member for all expenses (including reasonable legal
and accounting fees) incurred as Tax Matters Member pursuant to this Article
11 in connection with any administrative or judicial proceeding with respect
to the tax liability of the Members as long as the Tax Matters Member has
determined in good faith that the Tax Matters Member's course of conduct was
in, or not opposed to, the best interest of the Company.  The taking of any
action and the incurring of any expense by the Tax Matters Member in
connection with any such proceeding, except to the extent provided herein or
required by law, is a matter in the sole discretion of the Tax Matters Member.

     11.4 Information Furnished.  To the extent and in the manner provided by
applicable law and Regulations, the Tax Matters Member shall furnish the name,
address, profits and loss interest, and taxpayer identification number of each

     11.5 Notice of Proceedings, etc.  The Tax Matters Member shall use best
efforts to keep each Member informed of any administrative and judicial
proceedings for the adjustment at the Company level of any item required to be
taken into account by a Member for income tax purposes or any extension of the
period of limitations for making assessments of any tax against a Member with
respect to any Company item, or of any agreement with the Internal Revenue
Service that would result in any material change either in Income or Loss as
previously reported.

     11.6 Notices to Tax Matters Member.  Any Member that receives a notice of
an administrative proceeding under Section 6233 of the Code relating to the
Company shall promptly provide Notice to the Tax Matters Member of the
treatment of any Company item on such Member's Federal income tax return that
is or may be inconsistent with the treatment of that item on the Company's

and its terms within sixty (60) days after its date.

recognition of income, gain, losses and deductions and other items shall be on
the cash or accrual method of accounting for Federal income tax purposes, as
the Management Committee shall determine in its sole discretion in accordance
with applicable law.

     11.8 Tax Elections.  The Management Committee shall, in its sole
discretion, determine whether to make any available election.

return or otherwise.  No

state tax laws or to be treated as a corporation for federal tax purposes.

                                          TO
                       AMENDED AND RESTATED OPERATING AGREEMENT
                                          OF
                                 CHILES OFFSHORE LLC


          This Amendment No. 1 ("this Amendment") to the Amended and Restated
Operating Agreement dated as of December 16, 1997 (the "Operating Agreement") of
Chiles Offshore LLC, a Delaware limited liability company (the "Company") is
adopted by the Members signatory hereto, which in the aggregate hold not less
than 90% of the Membership Interests.

          WHEREAS, the Managers have unanimously proposed and recommended to the
Members that the Operating Agreement be amended as set forth in this Amendment;

          NOW THEREFORE, the Members signatory hereto, which in the aggregate
hold not less than 90% of the Membership Interests, agree as follows:

          1.   Capitalized Terms.  All capitalized terms used and not otherwise
defined herein are used with the meanings ascribed thereto in the Operating
Agreement.

          2.   Amendment.  The Operating Agreement is hereby amended by deleting
therefrom in its entirety the definition of "Tax Distribution" and replacing the
following therefor:

          "Tax Distribution"  means an amount equal to (i) the product of (x)
     the taxable income of the Company and (y) the highest effective marginal
     combined rate of Federal, state and city income tax, imposed on an
     individual taxpayer (taking into account for purposes of determining the
     rate of "state and city income tax" the highest combined New York State and
     New York City income tax rate imposed upon individuals) reduced by (ii) to
     the extent not previously taken into account, any income tax benefit
     attributable to the Company which could be realized (without regard to the
     actual realization) by its Members in the current or any prior Taxable Year
     or a portion thereof, commencing on or after April 28, 1998 (including any
     tax losses or tax credits) computed at the applicable percentage calculated
     pursuant to 


<PAGE>


     subclause (y) of clause (i) above for the Taxable Year that such benefit is
     taken into account for purposes of this computation.  Cash Distributions in
     respect of the Tax Distribution shall be made quarterly as provided in
     Section 4.1 hereof, based on a reasonable estimate of the amount of Tax
     Distribution for such Taxable Year.  The amount of Tax Distribution shall
     be computed by the accountants that regularly prepare the Company's tax
     returns and related information.

          3.   Miscellaneous.  From and after the Effective Date (as defined
below), all references in the Operating Agreement to "this Agreement" shall be
deemed references to the Amended and Restated Operating Agreement of Chiles
Offshore LLC, as amended by this Amendment No. 1.  Except as specifically
amended by this Amendment, the Operating Agreement remains in full force and
effect.  The section and other headings contained in this Amendment are for
reference purposes only and shall not affect the meaning or interpretation of
this Amendment.  This Amendment may be executed in several counterparts, all of
which together shall constitute one instrument binding on all Members,
notwithstanding that all the Members have not signed the same counterpart, or
any counterpart hereof; provided, however, this Amendment shall not become
effective unless and until Members that in the aggregate hold not less than 90%
of the Membership Interests shall have executed a counterpart hereof.  This
Amendment shall be construed according to and governed by the laws of the State
of Delaware without regard to principles and conflict of laws.

          IN WITNESS WHEREOF, this Amendment is executed by the Members
signatory hereto, which in the aggregate hold not less than 90% of the
Membership Interests, to be effective April 28, 1998 (the "Effective Date").

          SECTION 2.  Special Meetings.  Special meetings of stockholders for 
the transaction of such business as may properly come before the meeting may

together at least a majority of all the shares of the Corporation entitled to

          SECTION 3.  Notice of Meetings.  Written notice of all meetings of

or, if not so specified, at the place where the meeting is to be held.  The 
list shall also be produced and kept at the time and place of the meeting 
during the whole time thereof, and may be inspected by any stockholder who is 
present.

          The stock ledger shall be the only evidence as to who are the 
stockholders entitled to examine the stock ledger, the list required by this

entitled to vote registered in the name of such stockholder on the books of

appoint one or more inspectors.  In case any person who may be appointed as 
an inspector fails to appear or act, the vacancy may be filled by appointment 
made by the directors in advance of the meeting or at the meeting by the 
person presiding thereat.  Each inspector, if any, before entering upon the 
discharge of his or her duties, shall take and sign an oath faithfully to 
execute the duties of inspector at such meeting with strict impartiality and 
according to the best of his ability.  The inspectors, if 

                                          3

person presiding at the meeting, the inspector or inspectors, if any, shall 
make a report in writing of any challenge, question or matter determined by 
such inspector or inspectors and execute a certificate of any fact found by 
such inspector or inspectors.

of any other lawful action, the Board of Directors may fix a record date, 
which record date shall be not more than 60 days prior to such action.  If no 
record date is fixed, the record date for determining stockholders for any 
such purpose shall be at the close of business on the day on which the Board

          SECTION 1.  Certificates; Signatures.  The shares of the 
Corporation shall be represented by certificates, provided that the Board of 
Directors of the Corporation may provide by resolution or resolutions that 
some or all of any or all classes or series of its stock shall be 
uncertificated shares.  Any such resolution shall not apply to shares 
represented by a certificate until such certificate is surrendered to the 
Corporation.  Notwithstanding the adoption of such a resolution by the Board 
of Directors, every holder of stock represented by certificates and upon 
request every holder of uncertificated shares shall be entitled to have a 
certificate, signed by or in the name of the Corporation by the Chairman or 
Vice-Chairman of the Board of Directors, or the President or Vice-President, 
and by the Treasurer, if any, or an Assistant Treasurer, or the Secretary or 
an Assistant Secretary of the Corporation, representing the number of shares 
registered in certificate form.  Any and all signatures on any such 
certificate may be facsimiles.  In case any officer, transfer agent or 
registrar who has signed or whose facsimile signature has been placed upon a 
certificate shall have ceased to be such officer, transfer agent or registrar 
before such certificate is issued, it may be issued by the Corporation with 
the same effect as if he were such officer, transfer agent or registrar at 
the date of issue. The name of the holder of record of the shares represented 
thereby, with the number of such shares and the 

                                          11

          SECTION 2.  Transfers of Stock.  Upon compliance with provisions 
restricting the transfer or registration of transfer of shares of stock, if 
any, shares of capital stock shall be transferable on the books of the 
Corporation only by the holder of record thereof in person, or by duly 
authorized attorney, upon surrender and cancellation of certificates for a 
like number of shares, properly endorsed, and the payment of all taxes due 
thereon.

          SECTION 3.  Fractional Shares.  The Corporation may, but shall not 
be required to, issue certificates for fractions of a share where necessary 
to effect authorized transactions, or the Corporation may pay in cash the 
fair value of fractions of a share as of the time when those entitled to 
receive such fractions are determined, or it may issue scrip in registered or 
bearer form over the manual or facsimile signature of an officer of the 
Corporation or of its agent, exchangeable as therein provided for full 
shares, but such scrip shall not entitle the holder to any rights of a 
stockholder except as therein provided.

          The Board of Directors shall have power and authority to make all 
such rules and regulations as it may deem expedient concerning the issue, 
transfer and registration of certificates representing shares of the 
Corporation.

          SECTION 4.  Lost, Stolen or Destroyed Certificates.  The 
Corporation may issue a new certificate of stock in place of any certificate, 
theretofore issued by it, alleged to have been lost, stolen or destroyed, and 
the Board of Directors may require the owner of any lost, stolen or destroyed 
certificate, or his legal representative, to give the Corporation a bond 
sufficient to indemnify the Corporation against any claim that may be made 
against it on account of the alleged loss, theft or destruction of any such 
certificate or the issuance of any such new certificate.

Incorporation, the Board of Directors shall 

                                          12

<PAGE>


have full power to determine whether any, and, if any, what part of any, 
funds legally available for the payment of dividends shall be declared as 
dividends and paid to stockholders; the division of the whole or any part of 
such funds of the Corporation shall rest wholly within the lawful discretion 
of the Board of Directors, and it shall not be required at any time, against 
such discretion, to divide or pay any part of such funds among or to the 
stockholders as dividends or otherwise; and before payment of any dividend, 
there may be set aside out of any funds of the Corporation available for 
dividends such sum or sums as the Board of Directors from time to time, in 
its absolute discretion, thinks proper as a reserve or reserves to meet 
contingencies, or for equalizing dividends, or for repairing or maintaining 
any property of the Corporation, or for such other purpose as the Board of 
Directors shall think conducive to the interest of the Corporation, and the 
Board of Directors may modify or abolish any such reserve in the manner in 
which it was created.

                                     Ratification

          Any transaction, questioned in any lawsuit on the ground of lack of 
authority, defective or irregular execution, adverse interest of director, 
officer or stockholder, non-disclosure, miscomputation, or the application of 
improper principles or practices of accounting, may be ratified before or 
after judgment, by the Board of Directors or by the stockholders, and if so 
ratified shall have the same force and effect as if the questioned 
transaction had been originally duly authorized.  Such ratification shall be 
binding upon the Corporation and its stockholders and shall constitute a bar 
to any claim or execution of any judgment in respect of such questioned 
transaction.

                                      ARTICLE IX

figures as the Board of Directors shall determine.  The corporate seal may be 
used by printing, engraving, lithographing, stamping or otherwise 

                                          13

CORP., a Delaware corporation ("Finance" and, together with the Company, the
"Issuers"), the GUARANTORS listed on the signature pages hereto and U.S. BANK
TRUST NATIONAL ASSOCIATION, a national banking corporation, as trustee (the

         Each party agrees as follows for the benefit of the other party and for
the equal and ratable benefit of the Holders of the 10% Senior Notes Due 2008
(the "Notes") of the Issuers, as joint and several obligors:

                                    ARTICLE I

                   DEFINITIONS AND INCORPORATION BY REFERENCE

SECTION 1.1       Definitions.

         "Additional Assets" means (i) any property or assets (other than
Indebtedness and Capital Stock) in a Related Business, (ii) the Capital Stock of
a Person that becomes a Restricted Subsidiary as a result of the acquisition of
such Capital Stock by the Company or another Restricted Subsidiary or (iii)
Capital Stock constituting a minority interest in any Person that at such time
is a Restricted Subsidiary; provided, however, that any such Restricted
Subsidiary described in clause (ii) or (iii) above is primarily engaged in a
Related Business.

         "Additional Interest" has the meaning provided in Section 6 of the
Registration Rights Agreement.

         "Affiliate" of any specified Person means any other Person, directly or
indirectly, controlling or controlled by or under direct or indirect common
control with such specified Person. For the purposes of this definition,
"control" when used with respect to any Person means the power to direct the
management and policies of such Person, directly or indirectly, whether through
the ownership of voting securities, by contract or otherwise; and the terms
"controlling" and "controlled" have meanings correlative to the foregoing.

         "Allocated Portion" means, with respect to any Rig, a fraction, the
numerator of which is the Purchase Price of such Rig and the denominator is the
sum of the Purchase Prices of both Rigs.

         "Allocated Principal Amount" means, with respect to the principal
amount of any Note and any Rig, an amount equal to the product of (i) the
principal amount of such Note and (ii) the Allocated Portion.

         "Asset Disposition" means any sale, lease, transfer or other
disposition (or series of related sales, leases, transfers or dispositions) by
the Company or any Restricted Subsidiary, including any 


<PAGE>


disposition by means of a merger or consolidation (each referred to for the
purposes of this definition as a "disposition"), of (i) any shares of Capital
Stock of a Restricted Subsidiary (other than directors' qualifying shares or
shares required by applicable law to be held by a Person other than the Company
or a Restricted Subsidiary), (ii) all or substantially all the assets (other
than Capital Stock of an Unrestricted Subsidiary) of any division or line of
business of the Company or any Restricted Subsidiary or (iii) any other assets
(other than Capital Stock of an Unrestricted Subsidiary) of the Company or any
Restricted Subsidiary outside of the ordinary course of business of the Company
or such Restricted Subsidiary (other than, in the case of (i), (ii) and (iii)
above, (A) a disposition by a Restricted Subsidiary to the Company or by the
Company or a Restricted Subsidiary to a Restricted Subsidiary, (B) for purposes
of Section 4.6 only, a disposition that constitutes a Restricted Payment
permitted by Section 4.4 or a disposition specifically excepted from the
definition of Restricted Payment and (C) a disposition by the Company or a
Restricted Subsidiary of a Construction Option to an Unrestricted Subsidiary or
other Affiliate of the Company); provided, however, that Asset Disposition shall
not include (x) a transaction or series of related transactions for which the
Company or its Restricted Subsidiaries receive aggregate consideration less than

rise to the need to calculate the Consolidated Coverage Ratio is an Incurrence
of Indebtedness, or both, EBITDA and Consolidated Interest Expense for such
period shall be calculated after giving effect on a pro forma basis to such
Indebtedness as if such Indebtedness had been Incurred on the first day of such
period and the discharge of any other Indebtedness repaid, repurchased, defeased
or otherwise discharged with the proceeds of such new Indebtedness as if such
discharge had occurred on the first day of such period or (y) has repaid,
repurchased, defeased or otherwise discharged any Indebtedness since the

Consolidated Interest Expense for such period shall be calculated after giving
effect to such discharge of such Indebtedness, including with the proceeds of

Indebtedness of such Restricted Subsidiary to the extent the Company and
its continuing Restricted Subsidiaries are no longer liable for such
Indebtedness after such sale), (C) if since the beginning of such period the
Company or any Restricted Subsidiary (by merger or otherwise) shall have made an

Company or a Restricted Subsidiary during such period, EBITDA and Consolidated
Interest Expense for such period shall be calculated after giving pro forma
effect thereto as if such Asset Disposition, Investment or acquisition occurred
on the first day of such period. For purposes of this definition, whenever pro
forma effect is to be given to an acquisition of assets, the amount of income or
earnings relating thereto and the amount of Consolidated Interest Expense
associated with any Indebtedness Incurred in connection therewith, the pro forma
calculations shall be determined in good faith by a responsible financial or
accounting officer of the Company. If any Indebtedness bears a floating rate of
interest and is being given pro forma effect, the interest on such Indebtedness
shall be calculated as if the rate in effect on the date of determination had
been the applicable rate for the entire period (taking into account any Interest
Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement
has a remaining term in excess of 12 months). For purposes of this definition,

Subsidiary pursuant to a binding purchase agreement or the delivery since the
beginning of such period of a drilling rig to the Company or a Restricted
Subsidiary pursuant to a drilling rig construction contract, if such drilling
rig is subject to a binding drilling contract, the Company shall give pro forma
effect to the earnings (losses) of such drilling rig as if such drilling rig was
acquired on the first day of such period by basing such earnings (losses) on
(x)(a) revenues to be earned from any binding drilling contract of at least one
year's duration that will be applicable to any such drilling rig (including a
drilling rig owned by a Restricted Subsidiary) and in effect during such period
and (b) a good faith estimate of the operating costs of such drilling rig (as

Company).

                                     THE SECURITIES

SECTION 2.1       Form and Dating.

         Provisions relating to the Initial Notes, the Private Exchange Notes
and the Exchange Notes are set forth in Appendix 1, the Rule 144A/ Regulation S
Appendix, attached hereto (the "Appendix") which is hereby incorporated in and
expressly made part of this Indenture. The Initial Notes and the Trustee's
certificate of authentication shall be substantially in the form of Exhibit A to
the Appendix which is hereby incorporated in and expressly made a part of this
Indenture. The Exchange Notes, the Private Exchange Notes and the Trustee's
certificate of authentication shall be substantially in the form of Exhibit B,
which is hereby incorporated in and expressly made a part of this Indenture. The
Notes may have notations, legends or endorsements requirement by law, stock
exchange rule, agreements to which the Issuers are subject, if any, or usage
(provided that any such notation, legend or endorsement is in a form acceptable
to the Issuers). Each Note shall be dated the date of its authentication. The
terms of the Notes set forth in the Appendix, Exhibit A and Exhibit B are part
of the terms of this Indenture.

SECTION 2.2       Execution and Authentication.

         An officer of each of the Company and Finance shall sign the Notes for
the Issuers by manual or facsimile signature. If an Officer whose signature is
on a Note no longer holds that office at the time the Trustee authenticates the
Note, the Note shall be valid nevertheless. A Note shall not be valid until an
authorized signatory of the Trustee manually signs the certificate of
authentication on the Note. The signature shall be conclusive evidence that the
Note has been authenticated under this Indenture. The Trustee shall authenticate
and make available for delivery Notes for original issue in an aggregate
principal amount of $110 million, upon a written order signed by each of the
Company and Finance. Such order shall specify the amount of the Notes to be
authenticated and the date on which the original issue of Notes is to be
authenticated. The aggregate principal amount of Notes outstanding at any time
may not exceed that amount except as provided in Section 2.6. The Trustee may
appoint an authenticating agent acceptable to the Issuers to authenticate the
Notes, upon the consent of the Issuers to such appointment. Unless limited by
the terms of such appointment, an authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as any Registrar, Paying Agent or agent
for service of notices and demands.


                                       23

SECTION 2.3       Registrar and Paying Agent.

         The Issuers shall maintain an office or agency where Notes may be
presented for registration of transfer or for exchange (the "Registrar") and an
office or agency where Notes may be presented for payment (the "Paying Agent").
The Registrar, acting on behalf of and as agent for the Issuers, shall keep a
register (the "Notes Register") of the Notes and of their transfer and exchange.
The Issuers may have one or more co-registrars and one or more additional paying
agents.

         The term "Paying Agent" includes any additional paying agent. The
Issuers shall enter into an appropriate agency agreement with any Registrar,
Paying Agent or co-registrar not a party to this Indenture, which shall
incorporate the terms of the TIA. The agreement shall implement the provisions
of this Indenture that relate to such agent. The Issuers shall notify the
Trustee of the name and address of any such agent. If the Issuers fail to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.7. The
Issuers may act as Paying Agent, Registrar, co-Registrar or transfer agent.

         The Issuers initially appoint the Trustee as Registrar and Paying Agent
in connection with the Notes.

SECTION 2.4       Paying Agent to Hold Money in Trust.

         On or prior to each due date of the principal and interest on any Note,
the Issuers shall deposit or shall cause to be deposited with the Paying Agent a
sum sufficient to pay such principal and interest when so becoming due. The
Issuers shall require each Paying Agent (other than the Trustee) to agree in
writing that the Paying Agent shall hold in trust for the benefit of the
Noteholders or the Trustee all money held by the Paying Agent for the payment of
principal of or interest on the Notes and shall notify the Trustee of any
default by the Issuers in making any such payment. The Issuers at any time may
require a Paying Agent to pay all money held by it to the Trustee and to account
for any funds disbursed by the Paying Agent. Upon complying with this Section,
the Paying Agent shall have no further liability for the money delivered to the
Trustee.

SECTION 2.5       Noteholder Lists.

         The Trustee shall preserve, in as current a form as is reasonably
practicable, the most recent list available to it of the names and addresses of
the Noteholders. If the Trustee is not the Registrar, the Issuers shall furnish
to the Trustee, in writing at least five Business Days before each Interest
Payment Date and at such other times as the Trustee may request in writing, a
list in such form and as of such date as the Trustee may reasonably require of
the names and addresses of the Noteholders; provided that as long as the Trustee
is the Registrar, no such list need be furnished.


                                       24

SECTION 2.6       Replacement Notes.

         If a mutilated Note is surrendered to the Trustee or Registrar or if
the Holder of a Note claims that the Note has been lost, destroyed or wrongfully
taken, the Issuers shall issue, and the Trustee shall authenticate, a
replacement Note, if the requirements of Section 8-405 of the Uniform Commercial
Code are met and the Holder satisfies any other reasonable requirements of the
Trustee and the Issuers. Such Holder shall furnish an indemnity bond sufficient
in the judgment of the Issuers and the Trustee to protect the Issuers, the
Trustee, the Paying Agent, the Registrar and any co-registrar from any loss
which any of them may suffer if a security is replaced. The Issuers and the
Trustee may charge the Holder for their expenses in replacing a Note.

         Every replacement Note issued pursuant to the terms of this Section is
an obligation of the Issuers under this Indenture.

         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Notes.

SECTION 2.7       Outstanding Notes.

         Notes outstanding at any time are all Notes authenticated by the
Trustee except for those canceled by it, those delivered to it for cancellation
and those described in this Section as not outstanding. Subject to the
provisions of Section 12.6, a Note does not cease to be outstanding because the
Issuers or an Affiliate of the Issuers holds the security.

         If a Note is replaced pursuant to Section 2.6, it ceases to be
outstanding unless the Trustee and the Issuers receive proof satisfactory to
them that the replaced Note is held by a bona fide purchaser.

         If the Paying Agent (other than the Issuers, a Subsidiary or an
Affiliate of any thereof) segregates and holds in trust, in accordance with this
Indenture, on a redemption date or maturity date or, pursuant to Section 8.1(a),
within 91 days prior thereto, money sufficient to pay all principal and interest
payable on that redemption or maturity date with respect to the Notes (or
portions thereof) to be redeemed or maturing, as the case may be, then on and
after such date such Notes (or portions thereof) cease to be outstanding and on
and after such redemption or maturity date interest on them ceases to accrue.

SECTION 2.8       Temporary Notes.

      Until definitive Notes are ready for delivery, the Issuers may prepare and
the Trustee shall authenticate temporary Notes. Temporary Notes shall be
substantially in the form of definitive Notes but may have variations that the
Issuers consider appropriate for temporary Notes. Without

                                       25
<PAGE>

unreasonable delay, the Issuers shall prepare and the Trustee shall authenticate
definitive Notes and deliver them in exchange for temporary securities.

SECTION 2.9       Cancellation.

         The Issuers at any time may deliver Notes to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for registration of transfer, exchange or payment.
The Trustee, and no one else, shall cancel all Notes surrendered for
registration of transfer, exchange, payment or cancellation and destroy such
canceled Notes and provide a destruction certificate to the Issuers in respect
of such canceled Notes. The Trustee shall from time to time provide the Issuers
a list of all Notes that have been canceled as requested by the Issuers. The
Issuers may not issue new Notes to replace Notes it has redeemed, paid or
delivered to the Trustee for cancellation.

SECTION 2.10      Defaulted Interest.

         If the Issuers default in a payment of interest on the Notes, the
Issuers shall pay defaulted interest (plus 1.0% per annum in excess of such rate
on such defaulted interest to the extent lawful) in any lawful manner. The
Issuers may pay the defaulted interest to the persons who are Noteholders on a
subsequent special record date. The Issuers shall fix or cause to be fixed any
such special record date and payment date to the reasonable satisfaction of the
Trustee and shall promptly mail to each Noteholder a notice that states the
special record date, the payment date and the amount of defaulted interest to be
paid.

SECTION 2.11      CUSIP Numbers.

         The Issuers in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers,
either as printed on the Notes or as contained in any notice of a redemption,
and that reliance may be placed only on the other identification numbers printed
on the Notes, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Issuers will promptly notify the Trustee of any
change in the CUSIP numbers.

                                   ARTICLE III

                                   REDEMPTION

SECTION 3.1       Optional Redemption.

         If the Issuers elect to redeem Notes pursuant to paragraph 5 of the
Notes, they shall notify the Trustee in writing of the redemption date, the
principal amount of Notes to be redeemed and the paragraph of the Notes pursuant
to which the redemption will occur. The Issuers shall give each


                                       26
<PAGE>

notice to the Trustee provided for in this Section not less than 45 and not more
than 60 days before the redemption date unless the Trustee consents to a shorter
period. Such notice shall be accompanied by an Officers' Certificate from the
Issuers to the effect that such redemption will comply with the provisions
herein.

SECTION 3.2       Selection of Notes to Be Redeemed.

         If fewer than all the Notes are to be redeemed, the Trustee shall
select the Notes to be redeemed pro rata or by lot or by a method that complies
with applicable legal and securities exchange requirements, if any, and that the
Trustee considers fair and appropriate and in accordance with methods generally
used at the time of selection by fiduciaries in similar circumstances. The
Trustee shall make the selection from outstanding Notes not previously called
for redemption. The Trustee may select for redemption portions of the principal
of Notes that have denominations larger than $1,000. Notes and portions of Notes
the Trustee selects shall be in amounts of $1,000 or a whole multiple of $1,000.
Provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption. The Trustee shall notify the
Issuers promptly of the Notes or portions of Notes to be redeemed. In the event
the Issuers are required to make an offer to repurchase Notes pursuant to
Sections 4.8, 4.10 or 4.18 and the amount available for such offer is not evenly
divisible by $1,000, the Trustee shall promptly refund to the Issuers any
remaining funds, which in no event will exceed $1,000.

SECTION 3.3       Notice of Redemption.

         At least 30 days but not more than 60 days before a date for redemption
of Notes, the Issuers shall mail a notice of redemption by first-class mail to
the registered address appearing in the Note Register of each Holder of Notes to
be redeemed. The notice shall identify the Notes (including CUSIP numbers, if
any) to be redeemed and shall state:

                           (1)      the redemption date;

                           (2)      the redemption price;

                           (3)      the name and address of the Paying Agent;

                           (4)      that Notes called for redemption must be
         surrendered to the Paying Agent to collect the redemption price;

                           (5)      if fewer than all the outstanding Notes are 
         to be redeemed, the identification and principal amounts of the 
         particular Notes to be redeemed;

                           (6)     that, unless the Issuers defaults in making 
         such redemption payment, interest on Notes (or portion thereof) called 
         for redemption ceases to accrue on and after the redemption date;


                                       27

<PAGE>

                           (7) the paragraph of the Notes pursuant to which the
         Notes called for redemption are being redeemed;

                           (8)      the CUSIP number, if any, printed on the 
         Notes being redeemed; and

                           (9) that no representation is made as to the
         correctness or accuracy of the CUSIP number, if any, listed in such
         notice or printed on the Notes.

         At the Issuers's request, the Trustee shall give the notice of
redemption in the Issuers's names and at the Issuers's expense. In such event,
the Issuers shall provide the Trustee with the information required by this
Section.

SECTION 3.4       Effect of Notice of Redemption.

         Once notice of redemption is mailed, Notes called for redemption become
due and payable on the redemption date and at the redemption price stated in the
notice. Upon surrender to the Paying Agent, such Notes shall be paid at the
redemption price stated in the notice, plus accrued interest to the redemption
date. Such notice if mailed in the manner herein provided shall be conclusively
presumed to have been given, whether or not the Holder receives such notice.
Failure to give notice or any defect in the notice to any Holder shall not
affect the validity of the notice to any other Holder.

SECTION 3.5       Deposit of Redemption Price.

         Prior to 11:00 a.m. (New York City time) on the redemption date, the
Issuers shall deposit with the Trustee or Paying Agent (or, if either of the
Issuers or a Subsidiary is the Paying Agent, shall segregate and hold in trust)
money sufficient to pay the redemption price of and accrued interest (if any) on
all Notes or portions thereof to be redeemed on that date other than Notes or
portions of Notes called for redemption which have been delivered by the Issuers
to the Trustee for cancellation.

SECTION 3.6       Notes Redeemed in Part.

         Upon surrender of a Note that is redeemed in part (with, if the Issuers
or the Trustee so require, due endorsement by, or a written instrument of
transfer in form satisfactory to the Issuers and the Trustee duly executed by,
the Holder thereof or his attorney duly authorized in writing), the Issuers
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Note without service charge, a new Note or Notes of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Note so
surrendered.

                                    COVENANTS

SECTION 4.1       Payment of Notes.

         The Issuers shall promptly pay the principal of and interest on the
Notes on the dates and in the manner provided in the Notes and in this
Indenture. Principal and interest shall be considered paid on the date due if on
such date the Trustee or the Paying Agent holds in accordance with this
Indenture money sufficient to pay all principal and interest then due. The
Issuers shall pay interest on overdue principal at 1.0% per annum in excess of
the rate specified therefor in the Notes, and it shall pay interest on overdue
installments of interest at 1.0% per annum in excess of such rate to the extent
lawful.

SECTION 4.2       SEC Reports.

to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the
Company shall file with the SEC (unless the SEC will not accept such a filing)
and provide within 15 days to the Trustee and the Noteholders such annual
reports and such information, documents and other reports as are specified in
Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. company
subject to such Sections, such information, documents and other reports to be so
filed and provided at the times specified for the filing of such information,
documents and reports under such Sections. In addition, whether or not required
by the rules and regulations of the SEC, the Company will file a copy of all
such information and reports with the SEC for public availability (unless the
SEC will not accept such filing). In addition, the Company shall furnish to the
Noteholders and to prospective investors, upon the requests of such Noteholders,
any information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act so long as the Notes are not freely transferable under the
Securities Act. The Company also shall comply with the other provisions of TIA
Section 314(a).

         Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Issuers's
compliance with any of their covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

SECTION 4.3       Limitation on Indebtedness.

                  (a) The Company shall not, and shall not permit any Restricted
Subsidiary to, Incur, directly or indirectly, any Indebtedness unless, after
giving effect to such Incurrence, the Consolidated Coverage Ratio would exceed
2.0 to 1.0.

the Restricted Subsidiaries may Incur any or all of the following 
Indebtedness:

               (1) Indebtedness (including reimbursement obligations in 
     respect of letters of credit outstanding under the Bank Facility that 
     are Indebtedness) of the Company Incurred pursuant to the Bank Facility 
     or any other credit or loan agreement (and any Guarantees in respect 
     thereof by Restricted Subsidiaries that are Subsidiary Guarantors in 
     accordance with this Indenture) in an aggregate principal amount which, 
     when taken together with the principal amount of all other Indebtedness 
     Incurred pursuant to this clause (1) and then outstanding, does not 
     exceed $25 million;

               (2) Indebtedness of the Company or any Restricted Subsidiary 
     owed to and held by the Company or any Wholly Owned Restricted 
     Subsidiary; provided, however, that any subsequent issuance or transfer 
     of any Capital Stock which results in any such Wholly Owned Restricted 
     Subsidiary ceasing to be a Wholly Owned Restricted Subsidiary or any 
     subsequent transfer of such Indebtedness (other than to another Wholly 
     Owned Restricted Subsidiary) shall be deemed, in each case, to 
     constitute the Incurrence of such Indebtedness by the Company or such 
     Restricted Subsidiary;

               (3) the Notes and the Subsidiary Guarantees;

               (4) Indebtedness outstanding on the Issue Date (other than

     (a)), does not exceed $10 million at any one time outstanding.

          (c) Notwithstanding the foregoing, neither the Company nor any 
Restricted Subsidiary shall Incur any Indebtedness pursuant to the foregoing

thereof are used, directly or indirectly, to Refinance any Subordinated

(i) in the event that an item of Indebtedness meets the criteria of more than 
one of the types of Indebtedness described above, the Company, in its sole 
discretion, will classify such item of Indebtedness and only be required to

SECTION 4.4       Limitation on Restricted Payments.

          (a) The Company shall not, and shall not permit any Restricted 
Subsidiary to, directly or indirectly, make a Restricted Payment if at the 
time the Company or such Restricted Subsidiary makes, and after giving effect 
to, the proposed Restricted Payment:

               (i) a Default shall have occurred and be continuing (or would 
     result therefrom);

               (ii) the Company, or such Restricted Subsidiary, as 
     applicable, are not able to Incur an additional $1.00 of Indebtedness 
     under Section 4.3(a); or

               (iii) the aggregate amount of such Restricted Payment and all 
     other Restricted Payments since the Issue Date would exceed the sum of:

                    (A) 50% of the Consolidated Net Income accrued during the 
          period (treated as one accounting period) from the beginning of the 
          fiscal quarter immediately following the fiscal quarter during 
          which the Notes are originally issued to the end of the most 
          recently ended fiscal quarter for which financial statements are 
          available at the time of such Restricted Payment (or, in case such 
          Consolidated Net Income shall be a deficit, minus 100% of such 
          deficit);

                    (B) the aggregate Net Cash Proceeds received by the 
          Company from capital contributions or the issuance or sale of its 
          Capital Stock (other than Disqualified Stock) subsequent to the 
          Issue Date (other than an issuance or sale to a Subsidiary of the 
          Company);

                    (C) the amount by which Indebtedness of the Company is 
          reduced on the Company's balance sheet upon the conversion or 
          exchange (other than by a Subsidiary of the Company) subsequent to 
          the Issue Date, of any Indebtedness of the Company or a Restricted 
          Subsidiary for Capital Stock (other than Disqualified Stock) of the 
          Company (less the amount of any cash, or the fair value of any 
          other property,

                                       31


<PAGE>



          distributed by the Company upon such conversion or exchange), 
          whether pursuant to the terms of such Indebtedness or pursuant to 
          an agreement with a creditor to engage in an equity for debt 
          exchange; and

                    (D) an amount equal to the sum of (x) the net reduction 
          in Investments in Unrestricted Subsidiaries resulting from the 
          receipt of dividends, repayments of loans or advances or other 
          transfers of assets or proceeds from the disposition of Capital 
          Stock or other distributions or payments, in each case to the 
          Company or any Restricted Subsidiary from, or with respect to, 
          interests in Unrestricted Subsidiaries, and (y) the portion 
          (proportionate to the Company's equity interest in such Subsidiary) 
          of the fair market value of the net assets of an Unrestricted 
          Subsidiary at the time such Unrestricted Subsidiary is designated a 
          Restricted Subsidiary; provided, however, that the foregoing sum 
          shall not exceed, in the case of any Unrestricted Subsidiary, the 
          amount of Investments previously made (and treated as a Restricted 
          Payment) by the Company or any Restricted Subsidiary in such 
          Unrestricted Subsidiary subsequent to the Issue Date.

          (b) The provisions of Section 4.4(a) shall not prohibit:

               (i) any purchase or redemption of Capital Stock or 
     Subordinated Obligations of the Company made by exchange for, or out of 
     the proceeds of the substantially concurrent sale of, Capital Stock of 
     the Company (other than (A) Disqualified Stock or (B) Capital Stock 
     issued or sold to a Subsidiary of the Company) or out of the proceeds of 
     a substantially concurrent capital contribution to the Company; 
     provided, however, that (x) such purchase, capital contribution or 
     redemption shall be excluded in the calculation of the amount of 
     Restricted Payments and (y) the Net Cash Proceeds from such sale of 
     Capital Stock or capital contribution shall be excluded from Section 
     4.4(a)(iii)(B);

               (ii) any purchase, repurchase, redemption, defeasance or other 
     acquisition or retirement for value of Subordinated Obligations made by 
     exchange for, or out of the net proceeds of the substantially concurrent 
     sale of, Indebtedness of the Company which is permitted to be Incurred 
     pursuant to Section 4.3; provided, however, that such purchase, 
     repurchase, redemption, defeasance or other acquisition or retirement 
     for value shall be excluded in the calculation of the amount of 
     Restricted Payments;

               (iii) dividends paid within 60 days after the date of 
     declaration thereof if at such date of declaration such dividend would 
     have complied with Section 4.4(a); provided, however, that such dividend 
     shall be included in the calculation of the amount of Restricted 
     Payments;

               (iv) for so long as the Company is a partnership or 
     substantially similar pass-through entity for Federal income tax 
     purposes, the making of Permitted Quarterly Tax


                                       32
<PAGE>

     Distributions in compliance with this Section; provided, however, that 
     such distributions shall be excluded in the calculation of the amount of 
     Restricted Payments; and

               (v) the repurchase of Capital Stock of the Company from 
     directors, officers or employees of the Company pursuant to the terms of 
     an employee benefit plan or employment or other agreement; provided that 
     the aggregate amount of all such repurchases shall not exceed $1 million 
     in any fiscal year, and $5 million in the aggregate.

          (c) For so long as the Company is a partnership or substantially 
similar pass-through entity for Federal income tax purposes, the Company may 
make cash distributions to its members, during each Quarterly Payment Period, 
in an aggregate amount not to exceed the Permitted Quarterly Tax Distribution 
in respect of the related Estimation Period. If any portion of a Permitted 
Quarterly Tax Distribution is not distributed during such Quarterly Payment 
Period, the Permitted Quarterly Tax Distribution payable during the 
immediately following Quarterly Payment Period shall be increased by such 
undistributed portion.

     Within 10 days following the Company's filing of Internal Revenue 
Service Form 1065 for the immediately preceding taxable year, the Tax Amounts 
CPA shall file with the Trustee a written statement indicating in reasonable 
detail the calculation of the True-Up Amount. In the case of a True-Up Amount 
due to the members, the Permitted Quarterly Tax Distribution payable during 
the immediately following Quarterly Payment Period shall be increased by such 
True-Up Amount. In the case of a True-Up Amount due to the Company, the 
Permitted Quarterly Tax Distribution payable during the immediately following 
Quarterly Payment Period shall be reduced by such TrueUp Amount and the 
excess, if any, of the True-Up Amount over such Permitted Quarterly Tax 
Distribution shall be applied to reduce the immediately following Permitted 
Quarterly Tax Distributions until such True-Up Amount is entirely offset.

SECTION 4.5       Limitation on Restrictions on Distributions from Restricted 
Subsidiaries.

     The Company shall not, and shall not permit any Restricted Subsidiary 
to, create or otherwise cause or permit to exist or become effective any 
consensual encumbrance or restriction on the ability of any Restricted 
Subsidiary to (a) pay dividends or make any other distributions on its 
Capital Stock to the Company or a Restricted Subsidiary or pay any 
Indebtedness owed to the Company, (b) make any loans or advances to the 
Company or (c) transfer any of its property or assets to the Company, except:

               (i)  any encumbrance or restriction pursuant to the Bank 
     Facility or any other agreement in effect at or entered into on the 
     Issue Date;

               (ii) any encumbrance or restriction with respect to a 
     Restricted Subsidiary pursuant to an agreement relating to any 
     Indebtedness Incurred by such Restricted Subsidiary on or prior to the 
     date on which such Restricted Subsidiary was acquired by the Company 
     (other than Indebtedness Incurred as consideration in, or to provide all 
     or any portion of the

                                       33

<PAGE>

     funds or credit support utilized to consummate, the transaction or 
     series of related transactions pursuant to which such Restricted 
     Subsidiary became a Restricted Subsidiary or was acquired by the 
     Company) and outstanding on such date;

               (iii) any encumbrance or restriction pursuant to an agreement 
     effecting Refinancing Indebtedness Incurred pursuant to an agreement 
     referred to in clause (i) or (ii) of this Section 4.5 or this clause 
     (iii) or contained in any amendment to an agreement referred to in 
     clause (i) or (ii) of this Section 4.5 or this clause (iii); provided, 
     however, that the encumbrances and restrictions with respect to any such 
     Restricted Subsidiary contained in any such refinancing agreement or 
     amendment are no less favorable to the Noteholders than encumbrances and 
     restrictions with respect to such Restricted Subsidiary contained in 
     such agreements;

               (iv) any such encumbrance or restriction consisting of 
     customary non-assignment provisions in leases to the extent such 
     provisions restrict the subletting, assignment or transfer of the lease 
     or the property leased thereunder or in purchase money financings;

               (v) in the case of Section 4.5(c), restrictions contained in 
     security agreements or mortgages securing Indebtedness of a Restricted 
     Subsidiary to the extent such restrictions restrict the transfer of the 
     property subject to such security agreements or mortgages;

               (vi) encumbrances or restrictions imposed by operation of any 
     applicable law, rule, regulation or order; and

               (vii) any restriction with respect to a Restricted Subsidiary 
     imposed pursuant to an agreement entered into for the sale or 
     disposition of all or substantially all the Capital Stock or assets of 
     such Restricted Subsidiary pending the closing of such sale or 
     disposition.

SECTION 4.6       Limitation on Sales of Assets and Subsidiary Stock.

          (a) The Company shall not, and shall not permit any Restricted 
Subsidiary to, directly or indirectly, sell, lease, transfer or otherwise 
dispose of the Escrowed Property other than in accordance with the Escrow 
Agreement and the Escrow Security Agreement. The Company shall not, and shall 
not permit any Restricted Subsidiary to, directly or indirectly, consummate 
any Asset Disposition of property other than the Escrowed Property, unless

               (i) the Company or such Restricted Subsidiary receives 
     consideration at the time of such Asset Disposition at least equal to 
     the fair market value (including the value of all non-cash 
     consideration), as determined in good faith by the Board of Directors, 
     of the shares and assets subject to such Asset Disposition, and at least 
     85% of the consideration

                                       34
<PAGE>

     thereof received by the Company or such Restricted Subsidiary is in the 
     form of cash or cash equivalents and

               (ii) an amount equal to 100% of the Net Available Cash from 
     such Asset Disposition is applied by the Company (or such Restricted 
     Subsidiary, as the case may be) (A) First, to either (i) prepay, repay, 
     redeem or purchase (and permanently reduce the commitments under) 
     Indebtedness under the Bank Facility or that is otherwise secured by its 
     assets subject to such Asset Disposition within 180 days from the date 
     of the receipt of such Net Available Cash (the "Receipt Date") or (ii) 
     to the extent the Company elects, to acquire Additional Assets within 
     180 days from the Receipt Date; (B) Second, to the extent of the balance 
     of such Net Available Cash after application in accordance with clause 
     (A), to make an offer pursuant to paragraph (b) below to the Holders to 
     purchase Notes pursuant to and subject to the conditions contained in 
     this Indenture; and (C) Third, to the extent of the balance of such Net 
     Available Cash after application in accordance with clauses (A) or (B) 
     to any other application or use not prohibited by this Indenture. 
     Notwithstanding the foregoing provisions of this paragraph, the Company 
     and the Restricted Subsidiaries shall not be required to apply the Net 
     Available Cash in accordance with this paragraph except to the extent 
     that the aggregate Net Available Cash from all Asset Dispositions which 
     is not applied in accordance with this paragraph exceeds $5 million (at 
     which time, the entire unutilized Net Available Cash, and not just the 
     amount in excess of $5 million, shall be applied pursuant to this 
     paragraph). Pending application of Net Available Cash pursuant to this 
     Section, such Net Available Cash shall be invested in Permitted 
     Investments.

     For the purposes of this Section, the following are deemed to be cash or 
cash equivalents: (x) the express assumption of Indebtedness of the Company 
or any Restricted Subsidiary and the release of the Company or such 
Restricted Subsidiary from all liability on such Indebtedness in connection 
with such Asset Disposition and (y) securities received by the Company or any 
Restricted Subsidiary from the transferee that are converted by the Company 
or such Restricted Subsidiary into cash within 90 days of closing the 
transaction.

          (b) In the event of an Asset Disposition that requires the purchase 
of the Notes pursuant to clause (a)(ii)(B) above, the Company will be 
required to purchase Notes tendered pursuant to an offer (an "Asset 
Disposition Offer") by the Company for the Notes at a purchase price of 100% 
of their principal amount plus accrued but unpaid interest in accordance with 
the procedures (including prorating in the event of oversubscription) set 
forth in Section 4.6(c). If the aggregate purchase price of Notes tendered 
pursuant to such offer is less than the Net Available Cash allotted to the 
purchase thereof, the Company will be required to apply the remaining Net 
Available Cash in accordance with clause (a)(ii)(C) above. The Company shall 
not be required to make such an offer to purchase Notes pursuant to this 
Section if the Net Available Cash available therefor is less than $5 million 
(which lesser amount shall be carried forward for purposes of determining 
whether such an offer is required with respect to any subsequent Asset 
Disposition).

                                       35

<PAGE>

          (c) Promptly, and in any event within 30 days after the Issuers 
become obligated to make an Asset Disposition Offer, the Issuers shall be 
obligated to deliver to the Trustee and send, by first-class mail to each 
Holder, at the address appearing in the Note Register, a written notice 
stating that the Holder may elect to have his Notes purchased by the Issuers 
either in whole or in part (subject to prorationing as hereinafter described 
in the event the Asset Disposition Offer is oversubscribed) in integral 
multiples of $1,000 of principal amount, at the applicable purchase price. 
The notice, which shall govern the terms of the Asset Disposition Offer, 
shall include such disclosures as are required by law and shall specify (i) 
that the Asset Disposition Offer is being made pursuant to this Section 4.6; 
(ii) the purchase price (including the amount of accrued interest, if any) 
for each Note and the purchase date not less than 30 days nor more than 60 
days after the date of such notice (the "Asset Disposition Purchase Date"); 
(iii) that any Note not tendered or accepted for payment will continue to 
accrue interest in accordance with the terms thereof; (iv) that, unless the 
Issuers default on making the payment, any Note accepted for payment pursuant 
to the Asset Disposition Offer shall cease to accrue interest on and after 
the Asset Disposition Purchase Date; (v) that Noteholders electing to have 
Notes purchased pursuant to an Asset Disposition Offer will be required to 
surrender their Notes to the Paying Agent at the address specified in the 
notice at least three business days prior to the Asset Disposition Purchase 
Date and must complete any form letter of transmittal proposed by the Issuers 
and acceptable to the Trustee and the Paying Agent; (vi) that Noteholders 
will be entitled to withdraw their election if the Paying Agent receives, not 
later than one business day prior to the Asset Disposition Purchase Date, a 
tested telex, facsimile transmission or letter setting forth the name of the 
Noteholder, the principal amount of Notes the Noteholder delivered for 
purchase, the Note certificate number (if any) and a statement that such 
Noteholder is withdrawing its election to have such Notes purchased; (vii) 
that if Notes in a principal amount in excess of the aggregate principal 
amount which the Issuers has offered to purchase are tendered pursuant to the 
Asset Disposition Offer, the Issuers shall purchase Notes on a pro rata basis 
among the Notes tendered (with such adjustments as may be deemed appropriate 
by the Issuers so that only Notes in denominations of $1,000 or integral 
multiples of $1,000 shall be acquired); (viii) that Noteholders whose Notes 
are purchased only in part will be issued new Notes equal in principal amount 
to the unpurchased portion of the Notes surrendered; and (ix) the 
instructions that Note holders must follow in order to tender their Notes.

          (d) Not later than the date upon which written notice of an Asset 
Disposition Offer is delivered to the Trustee as provided below, the Issuers 
shall deliver to the Trustee an Officers' Certificate as to (i) the amount of 
the Asset Disposition Offer (the "Asset Disposition Offer Amount"), (ii) the 
allocation of the Net Available Cash from the Asset Dispositions pursuant to 
which such Asset Disposition Offer is being made and (iii) the compliance of 
such allocation with the provisions of Section 4.6(a). Upon the expiration of 
the period for which the Asset Disposition Offer remains open (the "Asset 
Disposition Offer Period"), the Issuers shall deliver to the Trustee for 
cancellation the Notes or portions thereof which have been properly tendered 
to and are to be accepted by the Issuers. Not later than 11:00 a.m. (New York 
City time) on the Asset Disposition Purchase Date, the Issuers shall 
irrevocably deposit with the Trustee or with a paying agent (or, if the 
Issuers are acting as Paying Agent, segregate and hold in trust) an amount in 
cash sufficient to pay the Asset Disposition Offer Amount for all Notes 
properly tendered to and accepted by the

                                       36
<PAGE>

Issuers. The Trustee shall, on the Asset Disposition Purchase Date, mail or 
deliver payment to each tendering Holder in the amount of the purchase price.

          (e) Holders electing to have a Note purchased will be required to 
surrender the Note, together with all necessary endorsements and other 
appropriate materials duly completed, to the Issuers at the address specified 
in the notice at least three Business Days prior to the Asset Disposition 
Purchase Date. Holders will be entitled to withdraw their election in whole 
or in part if the Trustee or the Issuers receives not later than one Business 
Day prior to the Asset Disposition Purchase Date, a facsimile transmission or 
letter setting forth the name of the Holder, the principal amount of the Note 
(which shall be $1,000 or an integral multiple thereof) which was delivered 
for purchase by the Holder, the aggregate principal amount of such Note (if 
any) that remains subject to the original notice of the Asset Disposition 
Offer and that has been or will be delivered for purchase by the Issuers and 
a statement that such Holder is withdrawing his election to have such Note 
purchased. If at the expiration of the Asset Disposition Offer Period the 
aggregate principal amount of Notes surrendered by Holders exceeds the Asset 
Disposition Offer Amount, the Issuers shall select the Notes to be purchased 
on a pro rata basis (with such adjustments as may be deemed appropriate by 
the Issuers so that only securities in denominations of $1,000, or integral 
multiples thereof, shall be purchased). Holders whose Notes are purchased 
only in part will be issued new Notes equal in principal amount to the 
unpurchased portion of the Notes surrendered.

          (f) A Note shall be deemed to have been accepted for purchase at 
the time the Trustee, directly or through an agent, mails or delivers payment 
therefor to the surrendering Holder.

          (g) The Company shall comply, to the extent applicable, with the 
requirements of Section 14(e) of the Exchange Act and any other securities 
laws or regulations in connection with the repurchase of Notes pursuant to 
this Section. To the extent that the provisions of any securities laws or 
regulations conflict with provisions of this Section, the Company shall 
comply with the applicable securities laws and regulations and shall not be 
deemed to have breached its obligations under this Section 4.6 by virtue 
thereof.

SECTION 4.7       Limitation on Transactions with Affiliates.

          (a) The Company shall not, and shall not permit any Restricted 
Subsidiary to, enter into any transaction (including the purchase, sale, 
lease or exchange of any property or the rendering of any service) with any 
Affiliate of the Company other than the Company or a Restricted Subsidiary 
(an "Affiliate Transaction") unless the terms thereof (1) are no less 
favorable to the Company or such Restricted Subsidiary than those that could 
be obtained at the time of such transaction in a comparable transaction in 
arm's-length dealings with a Person who is not such an Affiliate, (2) if such 
Affiliate Transaction involves an amount in excess of $1 million, (i) are set 
forth in writing and (ii) have been approved by a majority of the members of 
the Board of Directors of the Company, or such Restricted Subsidiary as the 
case may be, having no material personal financial stake in such Affiliate 
Transaction, and (3) if such Affiliate Transaction involves an amount in

                                       37

<PAGE>

excess of $5 million, have been determined by a nationally recognized 
investment banking firm to be fair, from a financial standpoint, to the 
Company or its Restricted Subsidiary, as the case may be.

          (b) The foregoing provisions of Section 4.7(a) shall not prohibit 
(i) any Permitted Investment or Restricted Payment permitted to be made 
pursuant to Section 4.4, or any payment or transaction specifically excepted 
from the definition of Restricted Payment, (ii) any issuance of securities, 
or other payments, awards or grants in cash, securities or otherwise pursuant 
to, or the funding of, employment arrangements, stock options, stock 
ownership or other employee benefit plans, and approved by the Board of 
Directors of the Company, (iii) the grant of stock options or similar rights 
to employees and directors pursuant to plans approved by the Board of 
Directors of the Company, (iv) loans or advances to officers, directors or 
employees in the ordinary course of business or pursuant to compensation 
plans or employment agreements approved by the Board of Directors of the 
Company, in an aggregate amount not to exceed $1 million in any calendar 
year, (v) the payment of reasonable fees to directors of the Company and its 
Restricted Subsidiaries who are not employees of the Company or its 
Restricted Subsidiaries, (vi) any transaction between the Company and a 
Wholly Owned Restricted Subsidiary or between Wholly Owned Restricted 
Subsidiaries, (vii) management and administrative services agreements in 
effect on the Issue Date that are disclosed in the Offering Memorandum 
relating to the Notes under the caption "Certain Relationships and Certain 
Transactions" and any amendments thereto (so long as any such amendment is 
not more disadvantageous to the holders of the Notes in any material respect 
than the original agreement as in effect on the Issue Date and complies with 
clause (a)(1) above).

SECTION 4.8       Right to Require Repurchase upon Change of Control.

          (a) Upon the occurrence of a Change of Control, each Holder shall 
have the right to require that the Issuers repurchase such Holder's Notes at 
a purchase price in cash equal to 101% of the principal amount thereof, plus 
accrued and unpaid interest, if any, to the date of repurchase (subject to 
the right of Holders of record on the relevant record date to receive 
interest due on the related Interest Payment Date), in accordance with the 
terms contemplated in Section 4.8(b).

          (b) Within 30 days following any Change of Control, unless notice 
of redemption of the Notes has been given pursuant to paragraph 5 of the 
Notes, the Issuers shall mail a notice to each Holder with a copy to the 
Trustee stating:

               (1) that a Change of Control has occurred and that such Holder 
     has the right to require the Issuers to purchase such Holder's Notes at 
     a purchase price in cash equal to 101% of the principal amount thereof, 
     plus accrued and unpaid interest, if any, to the date of purchase 
     (subject to the right of Holders of record on a record date to receive 
     interest on the relevant Interest Payment Date);

do not default in their redemption obligations pursuant to such election.

          (a) The Issuers shall deliver to the Trustee within 120 days after

SECTION 4.11      Limitation on Liens.

     The Company shall not, and shall not permit any Restricted Subsidiary 
to, directly or indirectly, create or permit to exist any Lien upon any of 
its property or assets, now owned or hereafter acquired, securing any 
obligation unless concurrently with the creation of such Lien effective 
provision is made to secure the Notes and the Subsidiary Guarantees equally 
and ratably with such obligation for so long as such obligation is so 
secured; provided, however, that, if such obligation is a Subordinated 
Obligation, the Lien securing such obligation shall be subordinated and 
junior to the Lien securing the Notes and the Subsidiary Guarantees with the 
same or lesser relative priority as such Subordinated Obligation shall have 
been with respect to the Notes and the Subsidiary Guarantees. The preceding 
restriction shall not require the Company or any Restricted Subsidiary to 
secure the Notes or the Subsidiary Guarantees if the Lien consists of the 
following:

          (a) Liens created by this Indenture and the Escrow Security 
Agreement;

          (b) Liens under the Bank Facility;

          (c) Liens existing as of the Issue Date;

          (e) Liens to secure Indebtedness issued by the Company or a 
Restricted Subsidiary for the purpose of financing all or a part of the 
purchase price of assets or property acquired or constructed in the ordinary 
course of business after the Issue Date; provided, however, that (i) the 
aggregate principal amount (or accreted value in the case of Indebtedness 
issued at a discount) of Indebtedness so issued shall not exceed the lesser 
of the cost or fair market value, as determined in good faith by the Board of 
Directors of the Company, of the assets or property so acquired or 
constructed, (ii) the Indebtedness secured by such Liens shall have been 
permitted to be Incurred under Section 4.3 and (iii) such Liens shall not 
encumber any other assets or property of the Company or any of its Restricted 
Subsidiaries other than such assets or property or any improvement on such 
assets or property and shall attach to such assets or property within 90 days 
of the construction or acquisition of such assets or property;

                                       41
<PAGE>

          (f) Liens on the assets or property of a Restricted Subsidiary 
existing at the time such Restricted Subsidiary becomes a Restricted 
Subsidiary and not issued as a result of (or in connection with or in 
anticipation of) such Restricted Subsidiary becoming a Restricted Subsidiary; 
provided, however, that such Liens do not extend to or cover any other 
property or assets of the Company or any of its other Restricted 
Subsidiaries; or

          (g) Liens securing Indebtedness issued to Refinance Indebtedness 
which has been secured by a Lien permitted under this Indenture and is 
permitted to be Refinanced under this Indenture; provided, however, that such 
Liens do not extend to or cover any property or assets of the Company or any 
of its Restricted Subsidiaries not securing the Indebtedness so Refinanced.

SECTION 4.12      Limitation on Sale/Leaseback Transactions.

     The Company shall not, and shall not permit any Restricted Subsidiary 
to, enter into any Sale/Leaseback Transaction with respect to any property 
unless (i) the Company or such Restricted Subsidiary would be (A) in 
compliance with Section 4.3 immediately after giving effect to such 
Sale/Leaseback Transaction and (B) entitled to create a Lien on such property 
securing the Attributable Debt with respect to such Sale/Leaseback 
Transaction without securing the Notes pursuant to Section 4.11, (ii) the net 
proceeds received by the Company or any Restricted Subsidiary in connection 
with such Sale/Leaseback Transaction are at least equal to the fair market 
value (as determined by the Board of Directors of the Company) of such 
property and (iii) the Company or such Restricted Subsidiary applies the 
proceeds of such transaction in compliance with Section 4.6.

SECTION 4.13      Limitation on Sale or Issuance of Capital Stock of Restricted 
Subsidiaries.

     The Company shall not sell or otherwise dispose of any shares of Capital 
Stock of a Restricted Subsidiary, and shall not permit any Restricted 
Subsidiary, directly or indirectly, to issue or sell or otherwise dispose of 
any shares of its Capital Stock to any Person (other than to the Company or a 
Wholly Owned Subsidiary) or permit any Person (other than the Company or a 
Wholly Owned Subsidiary) to own any Capital Stock of a Restricted Subsidiary, 
if in either case as a result thereof such Restricted Subsidiary would no 
longer be a Restricted Subsidiary; provided, however, that this provision 
shall not prohibit (x) the Company or any Restricted Subsidiary from selling, 
leasing or otherwise disposing of all of the Capital Stock of any Restricted 
Subsidiary or (y) the designation of a Restricted Subsidiary as an 
Unrestricted Subsidiary in compliance with this Indenture. The foregoing 
shall not apply to any Lien granted on the Capital Stock of a Restricted 
Subsidiary.

SECTION 4.14      Payment of Taxes and Other Claims.

     The Issuers shall, and shall cause each of their Restricted Subsidiaries 
to, pay or discharge or cause to be paid or discharged, before the same shall 
become delinquent, all taxes, assessments and governmental charges levied or 
imposed upon a Restricted Subsidiary's income, profits or property; provided, 
however, that neither the Issuers nor any of their Subsidiaries shall be 
required

                                       42
<PAGE>

to pay or discharge or cause to be paid or discharged any such tax, 
assessment, charge or claim whose amount, applicability or validity is being 
contested in good faith by appropriate negotiations or proceedings and for 
which disputed amounts adequate reserves have been made in accordance with 
GAAP.

SECTION 4.15      Maintenance of Office or Agency.

     The Issuers shall maintain in the Borough of Manhattan, the City of New 
York, an office or agency (which may be an office or agency of the Trustee, 
Registrar or co-Registrar), where Notes may be surrendered for registration 
of transfer or exchange or for presentation for payment and where notices and 
demands to or upon the Issuers in respect of the Notes and this Indenture may 
be served. The Company will give prompt written notice to the Trustee of the 
location, and any change in the location, of such office or agency. If at any 
time the Issuers shall fail to maintain any such required office or agency or 
shall fail to furnish the Trustee with the address thereof, such 
presentations, surrenders, notices and demands may be made or served at the 
address of the Trustee's office in New York City as set forth in Section 12.2.

     The Issuers may also from time to time designate one or more other 
offices or agencies where the Notes may be presented or surrendered for any 
or all such purposes and may from time to time rescind such designations; 
provided, however, that no such designation or rescission shall in any manner 
relieve the Issuers of their respective obligations to maintain an office or 
agency in the Borough of Manhattan, the City of New York, for such purposes. 
The Company will give prompt written notice to the Trustee of any such 
designation or rescission and of any change in the location of any such other 
office or agency. The Issuers hereby initially designate the Trustee's office 
in New York City as set forth in Section 12.2 as an agency of the Issuers in 
accordance with Section 2.3.

SECTION 4.16      Corporate Existence.

     Subject to Article 5 and Section 4.6, the Issuers shall do or cause to 
be done, at their own cost and expense, all things necessary to, and will 
cause each of their Restricted Subsidiaries to, preserve and keep in full 
force and effect the corporate, limited liability company or partnership 
existence and rights (charter and statutory), licenses and/or franchises of 
the Issuers and each of their Restricted Subsidiaries; provided, however, 
that the Issuers or any of their Restricted Subsidiaries shall not be 
required to preserve any such rights, licenses or franchises if the Board of 
Directors of the Company shall reasonably determine that the preservation 
thereof is no longer desirable in the conduct of the business of the Issuers 
and the Restricted Subsidiaries, taken as a whole.

SECTION 4.17      Future Subsidiary Guarantors.

     The Company shall cause each Restricted Subsidiary that is organized and 
existing under the laws of any State of the United States or the District of 
Columbia and that at any time becomes an obligor or guarantor with respect to 
any obligations under the Bank Facility to execute and deliver to the Trustee 
a supplemental indenture pursuant to which such Restricted Subsidiary will 
Guarantee

                                       43
<PAGE>

payment of the Notes on the same terms and conditions as those set forth in 
this Indenture. Each Subsidiary Guarantee will be limited in amount to an 
amount not to exceed the maximum amount that can be Guaranteed by the 
applicable Subsidiary Guarantor without rendering such Subsidiary Guarantee 
voidable under applicable law relating to fraudulent conveyance or fraudulent 
transfer or similar laws affecting the rights of creditors generally.

SECTION 4.18      Application of Event of Loss Proceeds.

          (a) If an Event of Loss occurs at any time with respect to a Rig 
(the Rig suffering such Event of Loss being the "Lost Rig"), the Company 
shall apply an amount equal to 100% of the Event of Loss Proceeds from such 
Event of Loss received by the Company (or such Restricted Subsidiary, as the 
case may be) (i) First, to either (A) prepay, repay, redeem or purchase (and 
permanently reduce the commitments under) Indebtedness under the Bank 
Facility or that is otherwise secured by the Rig subject to such Event of 
Loss within 180 days from the date of the receipt of such Event of Loss 
Proceeds (the "Loss Receipt Date") or (B) to the extent the Company elects, 
to acquire a Qualified Substitute Rig within 180 days from the Loss Receipt 
Date; (ii) Second, to the extent of the balance of such Event of Loss 
Proceeds after application in accordance with clause (i), to make an offer 
pursuant to paragraph (b) below to the Holders to purchase Notes pursuant to 
and subject to the conditions contained in this Indenture; and (iii) Third, 
to the extent of the balance of such Event of Loss Proceeds after application 
in accordance with clauses (i) or (ii) to any other application or use not 
prohibited by this Indenture. Pending application of Event of Loss Proceeds 
pursuant to this Section, such Event of Loss Proceeds shall be invested in 
Permitted Investments.

          (b) In the event of an Event of Loss that requires the purchase of 
the Notes pursuant to clause (a)(ii) above, the Issuers will be required to 
purchase Notes tendered pursuant to an offer (an "Event of Loss Offer") by 
the Issuers for the Notes at a purchase price of 101% of their principal 
amount plus accrued but unpaid interest in accordance with the procedures 
(including prorating in the event of oversubscription) set forth in this 
Indenture. If the aggregate purchase price of Notes tendered pursuant to such 
offer is less than the Event of Loss Proceeds allotted to the purchase 
thereof, the Issuers will be required to apply the remaining Event of Loss 
Proceeds in accordance with clause (a)(iii) above.

          (c) Promptly, and in any event within 30 days after the Issuers 
become obligated to make an Event of Loss Offer, the Issuers shall be 
obligated to deliver to the Trustee and send, by first-class mail to each 
Holder, at the address appearing in the Note Register, a written notice 
stating that the Holder may elect to have his Notes purchased by the Issuers 
either in whole or in part (subject to prorationing as hereinafter described 
in the event the Event of Loss Offer is oversubscribed) in integral multiples 
of $1,000 of principal amount, at the applicable purchase price. The notice, 
which shall govern the terms of the Event of Loss Offer, shall include such 
disclosures as are required by law and shall specify (i) that the Event of 
Loss Offer is being made pursuant to this Section 4.18; (ii) the purchase 
price (including the amount of accrued interest, if any) for each Note and 
the purchase date not less than 30 days nor more than 60 days after the date 
of such notice

                                       44


<PAGE>

(the "Event of Loss Purchase Date"); (iii) that any Note not tendered or 
accepted for payment will continue to accrue interest in accordance with the 
terms thereof; (iv) that, unless the Issuers default on making the payment, 
any Note accepted for payment pursuant to the Event of Loss Offer shall cease 
to accrue interest on and after the Event of Loss Purchase Date; (v) that 
Noteholders electing to have Notes purchased pursuant to an Event of Loss 
Offer will be required to surrender their Notes to the Paying Agent at the 
address specified in the notice at least three business days prior to the 
Event of Loss Purchase Date and must complete any form letter of transmittal 
proposed by the Issuers and acceptable to the Trustee and the Paying Agent; 
(vi) that Noteholders will be entitled to withdraw their election if the 
Paying Agent receives, not later than one business day prior to the Event of 
Loss Purchase Date, a tested telex, facsimile transmission or letter setting 
forth the name of the Noteholder, the principal amount of Notes the 
Noteholder delivered for purchase, the Note certificate number (if any) and a 
statement that such Noteholder is withdrawing its election to have such Notes 
purchased; (vii) that if Notes in a principal amount in excess of the 
aggregate principal amount which the Issuers has offered to purchase are 
tendered pursuant to the Event of Loss Offer, the Issuers shall purchase 
Notes on a pro rata basis among the Notes tendered (with such adjustments as 
may be deemed appropriate by the Issuers so that only Notes in denominations 
of $1,000 or integral multiples of $1,000 shall be acquired); (viii) that 
Noteholders whose Notes are purchased only in part will be issued new Notes 
equal in principal amount to the unpurchased portion of the Notes 
surrendered; and (ix) the instructions that Noteholders must follow in order 
to tender their Notes.

          (d) Not later than the date upon which written notice of an Event 
of Loss Offer is delivered to the Trustee as provided below, the Issuers 
shall deliver to the Trustee an Officers' Certificate as to (i) the amount of 
the Event of Loss Offer (the "Event of Loss Offer Amount"), (ii) the 
allocation of the Net Available Cash from the Event of Loss pursuant to which 
such Event of Loss Offer is being made and (iii) the compliance of such 
allocation with the provisions of Section 4.18(a). Upon the expiration of the 
period for which the Event of Loss Offer remains open (the "Event of Loss 
Offer Period"), the Issuers shall deliver to the Trustee for cancellation the 
Notes or portions thereof which have been properly tendered to and are to be 
accepted by the Issuers. Not later than 11:00 a.m. (New York City time) on 
the Event of Loss Purchase Date, the Issuers shall irrevocably deposit with 
the Trustee or with a paying agent (or, if the Issuers is acting as Paying 
Agent, segregate and hold in trust) an amount in cash sufficient to pay the 
Event of Loss Offer Amount for all Notes properly tendered to and accepted by 
the Issuers. The Trustee shall, on the Event of Loss Purchase Date, mail or 
deliver payment to each tendering Holder in the amount of the purchase price.

          (e) Holders electing to have a Note purchased will be required to 
surrender the Note, together with all necessary endorsements and other 
appropriate materials duly completed, to the Issuers at the address specified 
in the notice at least three Business Days prior to the Event of Loss 
Purchase Date. Holders will be entitled to withdraw their election in whole 
or in part if the Trustee or the Issuers receives not later than one Business 
Day prior to the Event of Loss Purchase Date, a facsimile transmission or 
letter setting forth the name of the Holder, the principal amount of the Note 
(which shall be $1,000 or an integral multiple thereof) which was delivered 
for purchase

                                       45
<PAGE>

by the Holder, the aggregate principal amount of such Note (if any) that 
remains subject to the original notice of the Event of Loss Offer and that 
has been or will be delivered for purchase by the Issuers and a statement 
that such Holder is withdrawing his election to have such Note purchased. If 
at the expiration of the Event of Loss Offer Period the aggregate principal 
amount of Notes surrendered by Holders exceeds the Event of Loss Offer 
Amount, the Issuers shall select the Notes to be purchased on a pro rata 
basis (with such adjustments as may be deemed appropriate by the Issuers so 
that only securities in denominations of $1,000, or integral multiples 
thereof, shall be purchased). Holders whose Notes are purchased only in part 
will be issued new Notes equal in principal amount to the unpurchased portion 
of the Notes surrendered.

          (f) A Note shall be deemed to have been accepted for purchase at 
the time the Trustee, directly or through an agent, mails or delivers payment 
therefor to the surrendering Holder.

          (g) The Issuers shall comply, to the extent applicable, with the 
requirements of Section 14(e) of the Exchange Act and any other securities 
laws or regulations in connection with the repurchase of Notes pursuant to 
this Section. To the extent that the provisions of any securities laws or 
regulations conflict with provisions of this Section, the Company shall 
comply with the applicable securities laws and regulations and shall not be 
deemed to have breached its obligations under this clause by virtue thereof.

SECTION 4.19      Insurance.

    The Company shall, or shall cause the Restricted Subsidiary owning a 
drilling rig or drilling rigs to, carry and maintain with respect to each Rig 
owned by it insurance payable in United States Dollars in amounts, against 
risks (including marine hull and machinery (including excess value) 
insurance, marine protection and indemnity insurance, war risks insurance and 
liability insurance and liability arising out of pollution and the spillage 
or leakage of cargo and cargo liability insurance) and in a form which is 
substantially equivalent to the coverage carried by other responsible and 
experienced companies engaged in the operation of drilling rigs similar to 
the Rigs and with insurance companies, underwriters, funds, mutual insurance 
associations or clubs of recognized standing. No insurance shall provide for 
a deductible in excess of $1,000,000 per occurrence. No insurance policy 
shall be subject to lapse without at least seven Business Days' prior notice 
to the Trustee.

     For purposes of insurance against total loss, each drilling rig is to be 
insured for an amount not less than the fair market value (as determined in 
good faith by the Board of Directors of the Company) and not less, when 
aggregated with the insurance on the other drilling rigs, than the 
outstanding principal amount of the Notes, Indebtedness under the Bank 
Facility and any other pari passu Indebtedness, in each case together with 
premium, if any, and accrued interest thereon.

to, take or knowingly omit to take, any action which action or omission might 
or would have the result of materially impairing the security interest with 
respect to the Collateral (as defined in the Escrow Security Agreement) for 
the benefit of the Collateral Agent, the Trustee and the Holders of the 
Notes, and the Company shall not, and shall not permit any Restricted 
Subsidiary to, grant to any Person other than the Collateral Agent, for the 
benefit of the Collateral Agent, the Trustee and the Holders of the Notes, 
any interest whatsoever in any of the Collateral.

SECTION 4.21      Deposit of Funds with Escrow Agent.

     The Issuers shall initially place that portion of the net proceeds 
realized from the Offering in the Interest Escrow Account held by the Escrow 
Agent for the benefit of the Holders of the Notes in cash as will be 
sufficient to pay in full the first two scheduled interest payments due on 
the Notes. The disbursement of such funds shall be governed by the Escrow 
Agreement and the Escrow Security Agreement.

     The Issuers shall place the balance of the net proceeds realized from 
the Offering in the Construction Escrow Account held by the Escrow Agent for 
the benefit of the Holders of the Notes in cash. The disbursement of such 
funds shall be governed by the Escrow Agreement and the Escrow Security 
Agreement.

SECTION 4.22      Amendments to Escrow Agreement and Escrow Security Agreement.

     The Company shall not, and shall not permit any Restricted Subsidiary 
to, amend, modify or supplement, or permit or consent to any amendment, 
modification or supplement of, the Escrow Agreement or the Escrow Security 
Agreement in any way that would be adverse to the Holders of the Notes.

Subsidiaries to, engage to any material extent in any business other than a 
Related Business.

business not related directly or indirectly to obtaining money or arranging
financing for the Company.

     Upon request of the Trustee, the Issuers will execute and deliver such 
further instruments and do such further acts as may be reasonably necessary 
or proper to carry out more effectively the purpose of this Indenture.

               (i) the resulting, surviving or transferee Person (the 
     "Successor Company") shall be a Person organized and existing under the 
     laws of the United States of America, any State thereof or the District 
     of Columbia, and the Successor Company (if not the Company or Finance, 
     as the case may be) shall expressly assume, by a supplemental indenture, 
     executed and delivered to the Trustee, in form satisfactory to the 
     Trustee, all the obligations of the Company or Finance, as the case may 
     be, under the Notes, this Indenture, the Escrow Agreement and the Escrow 
     Security Agreement;

               (ii) immediately after giving effect to such transaction (and 
     treating any Indebtedness which becomes an obligation of the Successor 
     Company or any Restricted Subsidiary as a result of such transaction as 
     having been Incurred by such Successor Company or such Subsidiary at the 
     time of such transaction), no Default shall have occurred and be 
     continuing;

               (iii) in the case of the Company, immediately after giving 
     effect to such transaction, the Successor Company would be able to Incur 
     an additional $1.00 of Indebtedness pursuant to paragraph (a) of Section 
     4.3;

               (iv) in the case of the Company, immediately after giving 
     effect to such transaction, the Successor Company shall have 
     Consolidated Net Worth in an amount that is not less than the 
     Consolidated Net Worth of the Company prior to such transaction, minus 
     any costs incurred in connection with such transaction; and

                                       48

<PAGE>

               (v) the Company or Finance, as the case may be, shall have 
     delivered to the Trustee an officer's certificate and an opinion of 
     counsel, each stating that such consolidation, merger or transfer and 
     such supplemental indenture (if any) comply with this Indenture.

     The Successor Company shall be the successor to the Company or Finance, 
as the case may be, and shall succeed to, and be substituted for, and may 
exercise every right and power of, the Company or Finance, as the case may 
be, under this Indenture, but the predecessor company, only in the case of a 
conveyance, transfer or lease, shall not be released from the obligation to 
pay the principal of and interest on the Notes.

     Notwithstanding the foregoing, (a) any Restricted Subsidiary may 
consolidate or merge with, or transfer its assets substantially as an 
entirety to, the Issuers and (b) the Issuers may consolidate or merge with, 
or transfer their assets substantially as an entirety to, an Affiliate solely 
for the purpose of effecting a Corporate Conversion, provided that, in either 
case, the requirements set forth in clauses (i) and (v) of the first 
paragraph of this Section are complied with.

                                       ARTICLE VI

                                 DEFAULTS AND REMEDIES

SECTION 6.1       Events of Default.

     An "Event of Default" occurs if:

               (i) the Issuers default in the payment of interest on the 
     Notes when due, and such default continues for a period of 30 days;

               (ii) the Issuers default in the payment of the principal of 
     any Note when due at its Stated Maturity, upon optional redemption, upon

               (iv) the Issuers fail to comply for 30 days after the notice 
     specified below with Section 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.10, 4.13, 
     4.17, 4.19, 4.20, 4.21, 4.22, 4.23, 4.24 or 5.1 (other than a failure to 
     purchase Notes when required under Section 4.8, 4.10 and 4.18);

               (v) the Issuers fail to comply for 60 days after the Issuers 
     receive the notice specified below with any of their other agreements in 
     this Indenture (other than those referred to in (i), (ii), (iii) or (iv) 
     above);

                                       49


<PAGE>

               (vi) Indebtedness of the Issuers or any Restricted Subsidiary 
     is not paid within any applicable grace period after final maturity or 
     is accelerated by the holders thereof because of a default and the total 
     amount of such Indebtedness unpaid or accelerated exceeds $10 million or 
     its foreign currency equivalent at the time;

               (vii) The Issuers or any Restricted Subsidiary that is a 
     Significant Subsidiary of the Issuers pursuant to or within the meaning 
     of any Bankruptcy Law:

                    (A) commence a voluntary case;

                    (B) consent to the entry of an order for relief against 
           the Issuers or such Subsidiary in an involuntary case in which it 
           is the debtor;

                    (C) consent to the appointment of a Custodian of the 
           Issuers or such Subsidiary or for any substantial part of their 
           property;

                    (D) make a general assignment for the benefit of their 
           creditors;

                    (E) or take any comparable action under any foreign laws 
           having a similar effect or purpose as the Bankruptcy Laws;

               (viii) a court of competent jurisdiction enters an
     order or decree under any Bankruptcy Law that:

                    (A) is for relief against the Issuers or any Significant 
           Subsidiary of the Issuers in an involuntary case;

                    (B) appoints a Custodian of the Issuers or any 
           Significant Subsidiary of the Issuers or for any substantial part 
           of the property of the Issuers or Significant Subsidiary; or

                    (C) orders the winding up or liquidation of the Issuers 
           or any Significant Subsidiary of the Issuers;

     (or any similar relief is granted under any foreign laws having a 
     similar effect or purpose as the Bankruptcy Laws) and the order or 
     decree remains unstayed and in effect for 60 days; or

          (ix) the rendering of any judgment or decree for the payment of 
     money in excess of $10 million, or its foreign equivalent at the time, 
     is entered against the Issuers or any Restricted Subsidiary if such 
     judgment or decree remains outstanding for a period of 60 days following 
     entry of such judgment and is not discharged, bonded, waived or stayed 
     within 30 days after notice thereof to the Issuers;

                                       50
<PAGE>

          (x) a Subsidiary Guarantee ceases to be in full force and effect 
     (other than in accordance with the terms of such Subsidiary Guarantee or 
     this Indenture) or a Subsidiary Guarantor denies or disaffirms its 
     obligations under its Subsidiary Guarantees; or

          (xi) the security interest under the Escrow Security Agreement 
     shall, at any time, cease to be in full force and effect for any reason 
     (other than by operation of the provisions of this Indenture and the 
     Escrow Security Agreement), or any security interest created thereunder 
     shall be declared invalid or unenforceable, or the Issuers or any 
     Restricted Subsidiary shall assert, in any pleading in any court of 
     competent jurisdiction that any such security interest is invalid or 
     unenforceable.

     However, a default under clause (iv) or (v) will not constitute an Event 
of Default until the Trustee or the Holders of 25% in principal amount of the 
outstanding Notes notify the Issuers of the default and the Issuers do not 
cure such default within the time specified after receipt of such notice.

     The foregoing will constitute Events of Default whatever the reason for 
any such Event of Default and whether it is voluntary or involuntary or is 
effected by operation of law or pursuant to any judgment, decree or order of 
any court or any order, rule or regulation of any administrative or 
governmental body. The term "Bankruptcy Law" means Title 11, United States 
Code, as amended, or any similar Federal or state law for the relief of 
debtors. The term "Custodian" means any receiver, trustee, assignee, 
liquidator, custodian or similar official under any Bankruptcy Law.

SECTION 6.2       Acceleration.

     If an Event of Default (other than an Event of Default specified in 
Section 6.1(vii) or (viii) with respect to the Issuers) occurs and is 
continuing, the Trustee by notice to the Issuers, or the Holders of at least 
25% in aggregate principal amount of the outstanding Notes by notice to the 
Issuers and the Trustee, may declare the principal of and accrued but unpaid 
interest on all the Notes to be due and payable. Upon such a declaration, 
such principal and interest shall be due and payable immediately. If an Event 
of Default specified in Section 6.1(vii) or (viii) relating to the Issuers 
occurs and is continuing, the principal of and interest on all the Notes will 
ipso facto become and be immediately due and payable without any declaration 
or other act on the part of the Trustee or any Noteholders. The Holders of a 
majority in principal amount of the outstanding Notes may by notice to the 
Trustee rescind an acceleration and its consequences if the rescission would 
not conflict with any judgment or decree and if all existing Events of 
Default have been cured or waived except nonpayment of principal or interest 
that has become due solely because of acceleration. No such rescission shall 
affect any subsequent Default or impair any right consequent thereto.

SECTION 6.3       Other Remedies.

     If an Event of Default occurs and is continuing, the Trustee may pursue 
any available remedy to collect the payment of principal of or interest on 
the Notes or to enforce the performance of any provision of the Notes or this 
Indenture.

                                       51
<PAGE>

     The Trustee may maintain a proceeding even if it does not possess any of 
the Notes or does not produce any of them in the proceeding. A delay or 
omission by the Trustee or any Noteholder in exercising any right or remedy 
accruing upon an Event of Default shall not impair the right or remedy or 
constitute a waiver of or acquiescence in the Event of Default. No remedy is 
exclusive of any other remedy. All available remedies are, to the extent 
permitted by law, cumulative.

SECTION 6.4       Waiver of Past Defaults.

     The Holders of a majority in principal amount of the outstanding Notes 
by notice to the Trustee may waive any past or existing Default and its 
consequences or compliance with any provisions of this Indenture except (i) a 
Default in the payment of the principal of or interest on a Note or (ii) a 
Default in respect of a provision that under Section 9.2 cannot be amended 
without the consent of each Noteholder affected. When a Default is waived, it 
is deemed cured, and any Event of Default arising therefrom shall be deemed 
to have been cured, but no such waiver shall extend to any subsequent or 
other Default or impair any consequent right.

SECTION 6.5       Control by Majority.

     The Holders of a majority in aggregate principal amount of the Notes 
then outstanding may direct the time, method and place of conducting any 
proceeding for any remedy available to the Trustee or of exercising any trust 
or power conferred on the Trustee. However, the Trustee may refuse to follow 
any direction that conflicts with law or this Indenture or, subject to 
Section 7.1, that the Trustee determines is unduly prejudicial to the rights 
of other Noteholders or would involve the Trustee in personal liability; 
provided, however, that the Trustee may take any other action deemed proper 
by the Trustee that is not inconsistent with such direction. Prior to taking 
any action hereunder, the Trustee shall be entitled to indemnification from 
the Noteholders satisfactory to it in its sole discretion against all losses 
and expenses caused by taking or not taking such action.

SECTION 6.6       Limitation on Suits.

     Subject to the provisions of this Indenture relating to the duties of 
the Trustee, in case an Event of Default occurs and is continuing, the 
Trustee will be under no obligation to exercise any of the rights or powers 
under this Indenture at the request or direction of any of the Holders unless 
such Holders have offered to the Trustee reasonable indemnity or security 
against any loss, liability or expense. Except to enforce the right to 
receive payment of principal, premium (if any) or interest when due, no 
Holder of a Note may pursue any remedy with respect to this Indenture or the 
Notes unless:

               (1) the Holder gives to the Trustee written notice stating 
     that an Event of Default is continuing;

               (2) the Holders of at least 25% in aggregate principal amount 
     of the Notes then outstanding make a written request to the Trustee to 
     pursue the remedy;

                                       52
<PAGE>

               (3) such Holder or Holders offer to the Trustee reasonable 
     security or indemnity against any loss, liability or expense;

               (4) the Trustee does not comply with the request within 60 
     days after receipt of the request and the offer of security or 
     indemnity; and

               (5) the Holders of a majority in aggregate principal amount of 
     the Notes then outstanding do not give the Trustee a direction 
     inconsistent with the request during such 60-day period.

     A Noteholder may not use this Indenture to prejudice the rights of 
another Noteholder or to obtain a preference or priority over another 
Noteholder.

SECTION 6.7       Rights of Holders to Receive Payment.

     Notwithstanding any other provision of this Indenture, the right of any 
Holder to receive payment of principal of and interest on the Notes held by 
such Holder, on or after the respective due dates expressed in the Notes, or 
to bring suit for the enforcement of any such payment on or after such 
respective dates, shall not be impaired or affected without the consent of 
such Holder.

SECTION 6.8       Collection Suit by Trustee.

     If an Event of Default specified in Section 6.1(i) or (ii) occurs and is 
continuing, the Trustee may recover judgment in its own name and as trustee 
of an express trust against the Issuers for the whole amount then due and 
owing (together with interest on any unpaid interest to the extent lawful) 
and the amounts provided for in Section 7.7.

SECTION 6.9       Trustee May File Proofs of Claim.

     The Trustee may file such proofs of claim and other papers or documents 
as may be necessary or advisable in order to have the claims of the Trustee 
and the Noteholders allowed in any judicial proceedings relative to the 
Issuers, their creditors or its property and, unless prohibited by law or 
applicable regulations, may vote on behalf of the Holders in any election of 
a trustee in bankruptcy or other Person performing similar functions, and any 
Custodian in any such judicial proceeding is hereby authorized by each Holder 
to make payments to the Trustee and, in the event that the Trustee shall 
consent to the making of such payments directly to the Holders, to pay to the 
Trustee any amount due it for the reasonable compensation, expenses, 
disbursements and advances of the Trustee, its agents and its counsel, and 
any other amounts due the Trustee under Section 7.7.

                                       53
<PAGE>

SECTION 6.10      Priorities.

     If the Trustee collects any money or property pursuant to this Article 
6, it shall pay out the money or property in the following order, subject to 
applicable law:

               FIRST: to the Trustee for amounts due under Section 7.7;

               SECOND: to the Noteholders for amounts due and unpaid on the 
     Notes for principal and interest, ratably, without preference or 
     priority of any kind, according to the amounts due and payable on the 
     Notes for principal and interest, respectively; and

               THIRD: to the Issuers.

     The Trustee may, upon prior written notice to the Issuers, fix a record 
date and payment date for any payment to the Noteholders pursuant to this 
Section. At least 15 days before such record date, the Issuers shall mail to 
each Noteholder and the Trustee a notice that states the record date, the 
payment date and amount to be paid.

SECTION 6.11      Undertaking for Costs.

     In any suit for the enforcement of any right or remedy under this 
Indenture or in any suit against the Trustee for any action taken or omitted 
by it as Trustee, a court in its discretion may require the filing by any 
party litigant in the suit of an undertaking to pay the costs of the suit, 
and the court in its discretion may assess reasonable costs, including 
reasonable attorneys' fees and expenses, against any party litigant in the 
suit, having due regard to the merits and good faith of the claims or 
defenses made by the party litigant. This Section does not apply to a suit by 
the Trustee, a suit by a Holder pursuant to Section 6.7 or a suit by Holders 
of more than 10% in aggregate principal amount of the outstanding Notes.

SECTION 6.12      Waiver of Stay or Extension Laws.

     The Issuers (to the extent they may lawfully do so) shall not at any 
time insist upon, or plead, or in any manner whatsoever claim or take the 
benefit or advantage of, any stay or extension law wherever enacted, now or 
at any time hereafter in force, which may affect the covenants or the 
performance of this Indenture; and the Issuers (to the extent that they may 
lawfully do so) hereby expressly waive all benefit or advantage of any such 
law, and shall not hinder, delay or impede the execution of any power herein 
granted to the Trustee, but shall suffer and permit the execution of every 
such power as though no such law had been enacted.

                                        TRUSTEE

SECTION 7.1       Duties of Trustee.

          (a) If an Event of Default has occurred and is continuing, the 
Trustee shall, in the exercise of its the rights and powers vested in it by 
this Indenture and use the same degree of care of a prudent Person in the 
conduct of such Person's own affairs.

          (b) Except during the continuance of an Event of Default:

               (1) the Trustee undertakes to perform such duties and only 
     such duties as are specifically set forth in this Indenture and no 
     implied covenants or obligations shall be read into this Indenture 
     against the Trustee; and

               (2) in the absence of bad faith on its part, the Trustee may 
     conclusively rely, as to the truth of the statements and the correctness 
     of the opinions expressed therein, upon certificates or opinions 
     furnished to the Trustee and conforming to the requirements of this 
     Indenture. However, in the case of any such certificates or opinions 
     which by any provision hereof are specifically required to be furnished 
     to the Trustee, the Trustee shall examine the certificates and opinions 
     to determine whether or not they conform to the requirements of this 
     Indenture.

          (c) The Trustee may not be relieved from liability for its own 
negligent action, its own negligent failure to act or its own willful 
misconduct, except that:

               (1) this paragraph does not limit the effect of paragraph 
     (b) of this Section;

                (2) the Trustee shall not be liable for any error of judgment 
     made in good faith by a Trust Officer unless it is proved that the 
     Trustee was negligent in ascertaining the pertinent facts; and

               (3) the Trustee shall not be liable with respect to any action 
     it takes or omits to take in good faith in accordance with a direction 
     received by it pursuant to Section 6.5.

          (d) Every provision of this Indenture that in any way relates
to the Trustee is subject to paragraphs (a), (b) and (c) of this Section and to
the provisions of the TIA.

          (e) Money held in trust by the Trustee need not be segregated
from other funds except to the extent required by law.

                                       55
<PAGE>

          (f) No provision of this Indenture shall require the Trustee to 
expend or risk its own funds or otherwise incur financial liability in the 
performance of any of its duties hereunder or in the exercise of any of its 
rights or powers, if it shall have reasonable grounds to believe that 
repayment of such funds or adequate indemnity against such risk or liability 
is not reasonably assured to it.

          (g) Every provision of this Indenture relating to the conduct or 
affecting the liability of or affording protection to the Trustee shall be 
subject to the provisions of this Section and to the provisions of the TIA.

SECTION 7.2       Rights of Trustee.

     Subject to Section 7.1,

          (a) The Trustee may rely on any document believed by it to be 
genuine and to have been signed or presented by the proper person. The 
Trustee need not investigate any fact or matter stated in the document.

          (b) Before the Trustee acts or refrains from acting, it may require 
an Officers' Certificate or an Opinion of Counsel. The Trustee shall not be 
liable for any action it takes or omits to take in good faith in reliance on 
the Officers' Certificate or Opinion of Counsel.

          (c) The Trustee may act through agents and shall not be responsible 
for the misconduct or negligence of any agent appointed with due care.

          (d) The Trustee shall not be liable for any action it takes or 
omits to take in good faith which it believes to be authorized or within its 
rights or powers; provided, however, that the Trustee's conduct does not 
constitute willful misconduct or negligence.

          (e) The Trustee may consult with counsel of its selection, and the 
advice or opinion of counsel with respect to legal matters relating to this 
Indenture and the Notes shall be full and complete authorization and 
protection from liability in respect to any action taken, omitted or suffered 
by it hereunder in good faith and in accordance with the advice or opinion of 
such counsel.

          (f) The Trustee shall be under no obligation to exercise any of the 
rights or powers vested in it by this Indenture at the request or direction 
of any of the Holders pursuant to this Indenture, unless such Holders shall 
have offered to the Trustee reasonable security or indemnity against the 
costs, expenses and liabilities which might be incurred by it in compliance 
with such request or direction.

          (g) Except with respect to Section 4.1, the Trustee shall have no 
duty to inquire as to the performance of the Issuers's covenants in Article 
4. In addition, the Trustee shall not be deemed to have knowledge of any 
Default or Event of Default except (i) any Default or Event of

                                       56

<PAGE>

Default occurring pursuant to Sections 6.1(i), 6.1(ii) and 4.1 or (ii) any 
Default or Event of Default of which the Trustee shall have received written 
notification or obtained actual knowledge.

SECTION 7.3       Individual Rights of Trustee.

     The Trustee in its individual or any other capacity may become the owner 
or pledgee of Notes and may otherwise deal with the Issuers or their 
respective Affiliates with the same rights it would have if it were not 
Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do 
the same with like rights. However, the Trustee must comply with Sections 
7.10 and 7.11.

SECTION 7.4       Trustee's Disclaimer.

     The Trustee shall not be responsible for and makes no representation as 
to the validity or adequacy of this Indenture or the Notes, it shall not be 
accountable for the Issuers' use of the proceeds from the Notes, and it shall 
not be responsible for any statement of the Issuers in this Indenture or in 
any document issued in connection with the sale of the Notes or in the Notes 
other than the Trustee's certificate of authentication.

SECTION 7.5       Notice of Defaults.

     If a Default occurs and is continuing and is known to the Trustee, the 
Trustee shall mail to each Noteholder notice of the Default within 90 days 
after it occurs. Except in the case of a Default in payment of principal of 
or interest on any Note, the Trustee may withhold the notice if and so long 
as the board of directors, the executive committee or a committee of its 
Trust Officers in good faith determines that withholding notice is not 
opposed to the interests of the Noteholders.

SECTION 7.6       Reports by Trustee to Holders.

     As promptly as practicable after each May 15 beginning with the May 15 
following the date of this Indenture, and in any event prior to July 15 in 
each year, the Trustee shall mail to each Noteholder a brief report dated as 
of May 15 that complies with TIA Section 313(a). The Trustee also shall 
comply with TIA Section 313(b). Prior to delivery to the Holders, the Trustee 
shall deliver to the Issuers a copy of any report it delivers to Holders 
pursuant to this Section 7.6.

     A copy of each report at the time of its mailing to the Noteholders 
shall be filed with the SEC and each stock exchange (if any) on which the 
Notes are listed. The Issuers agree to notify promptly the Trustee whenever 
the Notes become listed on any stock exchange and of any delisting thereof.

SECTION 7.7       Compensation and Indemnity.

     The Issuers shall pay to the Trustee from time to time such reasonable 
compensation for its services as the Issuers and the Trustee shall from time 
to time agree in writing. The Trustee's compensation shall not be limited by 
any law on compensation of a trustee of an express trust. The

                                       57
<PAGE>

Issuers shall reimburse the Trustee upon request for all reasonable 
out-of-pocket expenses incurred or made by it, including costs of collection, 
in addition to such compensation for its services, except any such expense, 
disbursement or advance as may arise from its negligence, willful misconduct 
or bad faith. Such expenses shall include the reasonable compensation and 
expenses, disbursements and advances of the Trustee's agents, counsel, 
accountants and experts. The Trustee shall provide the Issuers reasonable 
notice of any expenditure not in the ordinary course of business; provided 
that prior approval by the Issuers of any such expenditure shall not be a 
requirement for the making of such expenditure nor for reimbursement by the 
Issuers thereof. The Issuers shall indemnify each of the Trustee and any 
predecessor Trustees against any and all loss, damage, claim, liability or 
expense (including attorneys' fees and expenses) (other than taxes applicable 
to the Trustee's compensation hereunder) incurred by it in connection with 
the acceptance or administration of this trust and the performance of its 
duties hereunder. The Trustee shall notify the Issuers promptly of any claim 
for which it may seek indemnity. Failure by the Trustee to so notify the 
Issuers shall not relieve the Issuers of their obligations hereunder. The 
Issuers shall defend the claim and the Trustee shall cooperate in the defense 
of such claim. The Trustee may have separate counsel at its own expense. The 
Issuers need not reimburse any expense or indemnify against any loss, 
liability or expense incurred by the Trustee through the Trustee's own 
willful misconduct, negligence or bad faith. The Issuers need not pay for any 
settlement made without their written consent.

     To secure the Issuers's payment obligations in this Section, the Trustee 
shall have a lien prior to the Notes on all money or property held or 
collected by the Trustee other than money or property held in the Escrow 
Accounts or held in trust to pay principal of and interest on particular 
Notes.

     The Issuers's payment obligations pursuant to this Section shall survive 
the discharge of this Indenture. When the Trustee incurs expenses after the 
occurrence of a Default specified in Section 6.1(vii) or (viii) with respect 
to the Issuers, the expenses are intended to constitute expenses of 
administration under the Bankruptcy Law.

SECTION 7.8       Replacement of Trustee.

     The Trustee may resign at any time upon 30 days notice to the Issuers. 
The Holders of a majority in principal amount of the Notes then outstanding 
may remove the Trustee by so notifying the Trustee and may appoint a 
successor Trustee. The Issuers shall remove the Trustee if:

                    (1)    the Trustee fails to comply with Section 7.10;

                    (2)    the Trustee is adjudged bankrupt or insolvent;

                    (3)    a receiver or other public officer takes charge of 
     the Trustee or its property; or

                    (4)    the Trustee otherwise becomes incapable of acting.


                                       58
<PAGE>

     If the Trustee resigns, is removed by the Issuers or by the Holders of a 
majority in principal amount of the Notes and such Holders do not reasonably 
promptly appoint a successor Trustee, or if a vacancy exists in the office of 
Trustee for any reason (the Trustee in such event being referred to herein as 
the retiring Trustee), the Issuers shall promptly appoint a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its 
appointment to the retiring Trustee and to the Issuers. Thereupon the 
resignation or removal of the retiring Trustee shall become effective, and 
the successor Trustee shall have all the rights, powers and duties of the 
Trustee under this Indenture. The successor Trustee shall mail a notice of 
its succession to the Noteholders. The retiring Trustee shall promptly 
transfer all property held by it as Trustee to the successor Trustee, subject 
to the lien provided for in Section 7.7.

     If a successor Trustee does not take office within 60 days after the 
retiring Trustee resigns or is removed, the retiring Trustee or the Holders 
of 10% in principal amount of the Notes may petition any court of competent 
jurisdiction for the appointment of a successor Trustee. If the Trustee fails 
to comply with Section 7.10, any Noteholder may petition any court of 
competent jurisdiction for the removal of the Trustee and the appointment of 
a successor Trustee.

     Notwithstanding the replacement of the Trustee pursuant to this Section, 
the Issuers' obligations under Section 7.7 shall continue for the benefit of 
the retiring Trustee.

SECTION 7.9       Successor Trustee by Merger.

     If the Trustee consolidates with, merges or converts into, or transfers 
all or substantially all its corporate trust business or assets to, another 
corporation or banking association, the resulting, surviving or transferee 
corporation without any further act shall be the successor Trustee, provided 
that such corporation shall be eligible under this Article 7 and TIA Section 
3.10(a). In case at the time such successor or successors by merger, 
conversion or consolidation to the Trustee shall succeed to the trusts 
created by this Indenture any of the Notes shall have been authenticated but 
not delivered, any such successor to the Trustee may adopt the certificate of 
authentication of any predecessor trustee, and deliver such Notes so 
authenticated; and in case at that time any of the Notes shall not have been 
authenticated, any successor to the Trustee may authenticate such Notes 
either in the name of any predecessor hereunder or in the name of the 
successor to the Trustee; and in all such cases such certificates shall have 
the full force which it is anywhere in the Notes or in this Indenture 
provided that the certificate of the Trustee shall have.

SECTION 7.10      Eligibility; Disqualification.

     The Trustee shall at all times satisfy the requirements of TIA Section 
310(a). The Trustee shall have a combined capital and surplus of at least 
$25,000,000 as set forth in its most recent published annual report of 
condition. The Trustee shall comply with TIA Section 310(b); provided, 
however, that there shall be excluded from the operation of TIA Section 
310(b)(1) any indenture or indentures under which other securities or 
certificates of interest or participation in other securities

                                       59
<PAGE>

of the Issuers are outstanding if the requirements for such exclusion set 
forth in TIA Section 310(b)(1) are met.

SECTION 7.11      Preferential Collection of Claims Against Issuers.

     The Trustee shall comply with TIA Section 311(a), excluding any creditor 
relationship listed in TIA Section 311(b). A Trustee who has resigned or been 
removed shall be subject to TIA Section 311(a) to the extent indicated.

                                      ARTICLE VIII

                           DISCHARGE OF INDENTURE; DEFEASANCE

SECTION 8.1       Discharge of Liability on Notes; Defeasance.

     This Indenture will cease to be of further effect as to all outstanding 
Notes when:

          (a) When (i) the Issuers deliver to the Trustee all outstanding 
Notes (other than Notes replaced pursuant to Section 2.6) for cancellation or 
(ii) all outstanding Notes have become due and payable, whether at maturity 
or as a result of the mailing of a notice of redemption pursuant to Article 3 
hereof, and, in each case of this clause (ii), the Issuers irrevocably 
deposit or cause to be deposited with the Trustee United States dollars or 
Temporary Cash Investments sufficient to pay and discharge the entire 
indebtedness on the Notes not heretofore delivered to the Trustee for 
cancellation, for the principal of, premium, if any, and interest to the date 
of deposit (other than Notes replaced pursuant to Section 2.6), and if in 
either case the Issuers pay all other sums payable hereunder by the Issuers, 
then this Indenture shall, subject to Section 8.1(c), cease to be of further 
effect. The Trustee shall acknowledge satisfaction and discharge of this 
Indenture on demand of the Issuers accompanied by an Officers' Certificate 
and an Opinion of Counsel from the Issuers that all conditions precedent 
provided herein for relating to satisfaction and discharge of this Indenture 
have been complied with and at the cost and expense of the Issuers.

          (b) Subject to Sections 8.1(c) and 8.2, the Issuers at their option 
at any time may terminate (i) all of their obligations under the Notes and 
this Indenture ("legal defeasance option") or (ii) their obligations under 
Article 4 (and any omission to comply with such obligations shall not 
constitute a Default or Event of Default with respect to the Notes) and the 
operation of Sections 6.1(vi), 6.1(vii) (but only with respect to a 
Significant Subsidiary), 6.1(viii) (but only with respect to a Significant 
Subsidiary), 6.1(ix) and 5.1(iii) and 5.1(iv) ("covenant defeasance option"). 
The Issuers may exercise their legal defeasance option notwithstanding their 
prior exercise of their covenant defeasance option.

     If the Issuers exercise their legal defeasance option, payment of the 
Notes may not be accelerated because of an Event of Default with respect 
thereto. If the Issuers exercise their covenant defeasance option, payment of 
the Notes may not be accelerated because of an Event of Default

                                       60

<PAGE>

specified in Sections 6.1(iv), 6.1(vi) and 6.1(vii) (but only with respect to 
a Significant Subsidiary), or 6.1(viii) (but only with respect to a 
Significant Subsidiary) or 6.1(ix) or 6.1(x) or because of the failure of the 
Issuers to comply with Sections 5.1(iii) or 5.1(iv).

     If the Issuers exercise their legal defeasance option or their covenant 
defeasance option, each Subsidiary Guarantor will be released from all its 
obligations with respect to its Subsidiary Guarantee.

     Upon satisfaction of the conditions set forth herein and upon request of 
the Issuers, the Trustee shall acknowledge in writing the discharge of those 
obligations that the Issuers terminate.

          (c) Notwithstanding clauses (a) and (b) above, the Issuers's 
obligations in Sections 2.3, 2.4, 2.5, 2.6, 2.7, 7.7, 7.8, 8.4, 8.5 and 8.6 
shall survive until the Notes have been paid in full. Thereafter, the 
Issuers's obligations in Sections 7.7, 8.4 and 8.5 shall survive.

SECTION 8.2       Conditions to Defeasance.

     The Issuers may exercise their legal defeasance option or their covenant 
defeasance option only if:

               (1) the Issuers irrevocably deposit or cause to be deposited 
     in trust with the Trustee money or U.S. Government Obligations which, 
     through the scheduled payment of principal and interest in respect 
     thereof in accordance with their terms, will provide cash at such times 
     and in such amounts as will be sufficient to pay principal and interest 
     when due on all outstanding Notes (except Notes replaced pursuant to 
     Section 2.6) to maturity or redemption, as the case may be;

               (2) the Issuers deliver to the Trustee a certificate from a 
     nationally recognized firm of independent accountants expressing their 
     opinion that the payments of principal and interest when due and without 
     reinvestment on the deposited U.S. Government Obligations plus any 
     deposited money without investment will provide cash at such times and 
     in such amounts as will be sufficient to pay principal and interest when 
     due on all outstanding Notes (except Notes replaced pursuant to Section 
     2.6) to maturity or redemption, as the case may be;

               (3) 91 days pass after the deposit is made and during the 
     91-day period no Default specified in Section 6.1(vii) or (viii) with 
     respect to the Issuers occurs which is continuing at the end of the 
     period;

               (4) the deposit does not constitute a default under any 
     other material agreement binding on the Issuers;

                                       61

<PAGE>

               (5) the Issuers deliver to the Trustee an Opinion of Counsel 
     to the effect that the trust resulting from the deposit does not 
     constitute, or is qualified as, a regulated investment company under the 
     Investment Company Act of 1940;

               (6) in the case of the legal defeasance option, the Issuers 
     shall have delivered to the Trustee Opinions of Counsel stating that (i) 
     the Issuers have received from, or there has been published by, the 
     Internal Revenue Service a ruling, or (ii) since the date of this 
     Indenture there has been a change in the applicable Federal income tax 
     law, in either case to the effect that, and based thereon such Opinions 
     of Counsel shall confirm that, the Noteholders will not recognize 
     income, gain or loss for Federal income tax purposes as a result of such 
     deposit and defeasance and will be subject to Federal income tax on the 
     same amounts and in the same manner and at the same times as would have 
     been the case if such deposit and defeasance had not occurred;

               (7) in the case of the covenant defeasance option, the Issuers 
     shall have delivered to the Trustee Opinions of Counsel to the effect 
     that the Noteholders will not recognize income, gain or loss for Federal 
     income tax purposes as a result of such deposit and defeasance and will 
     be subject to Federal income tax on the same amounts and in the same 
     manner and at the same times as would have been the case if such deposit 
     and defeasance had not occurred; and

               (8) the Issuers deliver to the Trustee an Officers' 
     Certificate from an officer of each of the Company and Finance and an 
     Opinion of Counsel from an officer of each of the Company and Finance, 
     each stating that all conditions precedent to the defeasance and 
     discharge of the Notes as contemplated by this Article 8 have been 
     complied with.

     Opinions of Counsel required to be delivered under this Section may have 
qualifications customary for opinions of the type required and counsel 
delivering such Opinions of Counsel may rely on certificates of the Issuers 
or government or other officials customary for opinions of the type required, 
including certificates certifying as to matters of fact.

     Before or after a deposit, the Issuers may make arrangements 
satisfactory to the Trustee for the redemption of Notes at a future date in 
accordance with Article 3.

SECTION 8.3       Application of Trust Money.

     The Trustee shall hold in trust money or U.S. Government Obligations 
deposited with it pursuant to this Article 8. It shall apply the deposited 
money and the money from U.S. Government Obligations either directly or 
through the Paying Agent (including the Issuers acting as their own Paying 
Agents as the Trustee may determine) and in accordance with this Indenture to 
the payment of principal of and interest on the Notes.

                                       62

<PAGE>

SECTION 8.4       Repayment to Issuers.

     The Trustee and the Paying Agent shall notify the Issuers of any excess 
money or Notes held by them at any time and shall promptly turn over to the 
Issuers upon request any excess money or securities held by them at any time.

     Subject to any applicable abandoned property law, the Trustee and the 
Paying Agent shall pay to the Issuers upon written request any money held by 
them for the payment of principal or interest that remains unclaimed for two 
years, and, thereafter, Noteholders entitled to the money must look to the 
Issuers for payment as general creditors.

SECTION 8.5       Indemnity for Government Obligations.

     The Issuers shall pay and shall indemnify the Trustee against any tax, 
fee or other charge imposed on or assessed against deposited U.S. Government 
Obligations or the principal and interest received on such U.S. Government 
Obligations other than any such tax, fee or other charge which by law is for 
the account of the Holders of the defeased Notes; provided that the Trustee 
shall be entitled to charge any such tax, fee or other charge to such 
Holder's account.

SECTION 8.6       Reinstatement.

     If the Trustee or Paying Agent is unable to apply any money or U.S. 
Government Obligations in accordance with this Article 8 by reason of any 
legal proceeding or by reason of any order or judgment of any court or 
governmental authority enjoining, restraining or otherwise prohibiting such 
application, the Issuers's obligations under this Indenture and the Notes 
shall be revived and reinstated as though no deposit had occurred pursuant to 
this Article 8 until such time as the Trustee or Paying Agent is permitted to 
apply all such money or U.S. Government Obligations in accordance with this 
Article 8; provided, however, that, (a) if the Issuers have made any payment 
of interest on or principal of any Notes following the reinstatement of their 
obligations, the Issuers shall be subrogated to the rights of the Holders of 
such Notes to receive such payment from the money or U.S. Government 
Obligations held by the Trustee or Paying Agent and (b) unless otherwise 
required by any legal proceeding or any order or judgment of any court or 
governmental authority, the Trustee or Paying Agent shall return all such 
money and U.S. Government Obligations to the Issuers promptly after receiving 
a written request therefor at any time, if such reinstatement of the 
Issuers's obligations has occurred and continues to be in effect.

<PAGE>

SECTION 9.1       Without Consent of Holders.

     The Issuers and the Trustee may amend this Indenture or the Notes 
without notice to or consent of any Noteholder:

          (1)      to cure any ambiguity, omission, defect or inconsistency;

          (2)      to comply with Article 5;

          (3)      to provide for uncertificated Notes in addition to or in 
     place of certificated Notes; provided, however, that the uncertificated 
     Notes are issued in registered form for purposes of Section 163(f) of 
     the Code or in a manner such that the uncertificated Notes are as 
     described in Section 163(f)(2)(B) of the Code;

          (4)      to add guarantees with respect to the Notes,       
including the Subsidiary Guaranties;

          (5)      to secure the Notes;

          (6)      to add to the covenants of the Issuers or the Subsidiary 
     Guarantors for the benefit of the Holders or to surrender any right or 
     power herein conferred upon the Issuers or the Subsidiary Guarantors;

          (7)      to make any change that does not adversely affect the 
     rights of any Noteholder; or

          (8)      to comply with any requirements of the SEC in connection 
     with qualifying this Indenture under the TIA.

     After an amendment under this Section becomes effective, the Issuers 
shall mail to the Noteholders a notice briefly describing such amendment. The 
failure to give such notice to all Noteholders, or any defect therein, shall 
not impair or affect the validity of an amendment under this section.

SECTION 9.2       With Consent of Holders.

     The Issuers and the Trustee may amend this Indenture or the Notes 
without notice to any Noteholder but with the written consent of the Holders 
of at least a majority in principal amount of the Notes then outstanding. 
However, without the consent of each Holder of an outstanding Note affected 
thereby, an amendment may not:

          (1)      reduce the amount of Notes whose Holders must consent to an 
amendment;

                                       64

<PAGE>



          (2)      reduce the rate of or extend the time for payment of 
interest on any Note;

          (3)      reduce the principal of or extend the Stated Maturity of 
any Note;

          (4)      reduce the premium payable upon the redemption of any Note 
or change the time at which any Note may be redeemed in accordance with 
Article 3;

          (5)      make any Note payable in money other than that stated in 
the Note;

          (6)      impair the right of any Holder to receive payment of 
principal of and interest on such Holder's Notes on or after the due dates 
therefor or to institute suit for the enforcement of any payment on or with 
respect to such Holder's Notes;

          (7)      make any change in Section 6.4 or 6.7 or the second 
sentence of this Section;

          (8)      affect the ranking of the Notes in any material respect; or

          (9)      make any change in any Subsidiary Guarantee or the Escrow 
Security Agreement that would adversely affect the Holders or terminate the 
Lien of this Indenture or the Escrow Security Agreement on the Collateral or 
deprive the Holders of the security afforded by such Lien.

     The consent of the Holders under this Section is not necessary to 
approve the particular form of any proposed amendment. It is sufficient if 
such consent approves the substance of the proposed amendment. After an 
amendment under this Section becomes effective, the Issuers shall mail to the 
Noteholders a notice briefly describing such amendment. However, the failure 
to give such notice to all Noteholders, or any defect therein, shall not 
impair or affect the validity of an amendment under this Section.

SECTION 9.3       Compliance with Trust Indenture Act.

     Every amendment to this Indenture or the Notes shall comply with the TIA 
as then in effect.

SECTION 9.4       Revocation and Effect of Consents and Waivers.

     A consent to an amendment or a waiver by a Holder of a Note shall bind 
the Holder and every subsequent Holder of that Note or portion of the Note 
that evidences the same debt as the consenting Holder's Note, even if 
notation of the consent or waiver is not made on the Note. An amendment or 
waiver becomes effective once the requisite number of consents are received 
by the Issuers or the Trustee. After an amendment or waiver becomes 
effective, it shall bind every Noteholder.

                                       65

<PAGE>

     The Issuers may, but shall not be obligated to, fix a record date for 
the purpose of determining the Noteholders entitled to give their consent or 
take any other action described above or required or permitted to be taken 
pursuant to this Indenture. If a record date is fixed, then notwithstanding 
the immediately preceding paragraph, those Persons who were Noteholders at 
such record date (or their duly designated proxies), and only those Persons, 
shall be entitled to give such consent or to revoke any consent previously 
given or to take any such action, whether or not such Persons continue to be 
Holders after such record date. No such consent shall be valid or effective 
for more than 120 days after such record date.

SECTION 9.5       Notation on or Exchange of Notes.

     If an amendment changes the terms of a Note, the Trustee may require the 
Holder of the Note to deliver it to the Trustee. The Trustee may place an 
appropriate notation on the Note regarding the changed terms and return it to 
the Holder. Alternatively, if the Issuers or the Trustee so determine, the 
Issuers in exchange for the Note shall issue and the Trustee shall 
authenticate a new Note that reflects the changed terms. Failure to make the 
appropriate notation or to issue a new Note shall not affect the validity of 
such amendment.

SECTION 9.6       Trustee to Sign Amendments.

     The Trustee shall sign any amendment authorized pursuant to this Article 
9 if the amendment does not adversely affect the rights, duties, liabilities 
or immunities of the Trustee. If it does, the Trustee may but need not sign 
it. In signing such amendment the Trustee shall be entitled to receive 
indemnity reasonably satisfactory to it and to receive, and (subject to 
Section 7.1) shall be fully protected in relying upon, an Officers' 
Certificate from each of the Company and Finance and an Opinion of Counsel 
provided by each of the Company and Finance stating that such amendment 
complies with the provisions of Article 9 of this Indenture.

                                       ARTICLE X

                                 SUBSIDIARY GUARANTEES

SECTION 10.1      Guarantees.

     Each Subsidiary Guarantor hereby unconditionally and irrevocably 
guarantees, jointly and severally, to each Holder and to the Trustee and its 
successors and assigns (a) the full and punctual payment of principal of and 
interest on the Notes when due, whether at maturity, by acceleration, by 
redemption or otherwise, and all other monetary obligations of the Issuers 
under this Indenture and the Notes and (b) the full and punctual performance 
within applicable grace periods of all other obligations of the Issuers under 
this Indenture and the Notes (all the foregoing being hereinafter 
collectively called the "Obligations"). Each Subsidiary Guarantor further 
agrees that the Obligations may be extended or renewed, in whole or in part, 
without notice or further assent from such

                                       66

<PAGE>

Subsidiary Guarantor and that such Subsidiary Guarantor will remain bound 
under this Article 10 notwithstanding any extension or renewal of any 
Obligation.

     Each Subsidiary Guarantor waives presentation to, demand of, payment 
from and protest to the Issuers of any of the Obligations and also waives 
notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of 
any default under the Notes or the Obligations. The obligations of each 
Subsidiary Guarantor hereunder shall not be affected by (a) the failure of 
any Holder or the Trustee to assert any claim or demand or to enforce any 
right or remedy against the Issuers or any other Person under this Indenture, 
the Notes or any other agreement or otherwise; (b) any extension or renewal 
of any thereof; (c) any rescission, waiver, amendment or modification of any 
of the terms or provisions of this Indenture, the Notes or any other 
agreement; (d) the release of any security held by any Holder or the Trustee 
for the Obligations or any of them; (e) the failure of any Holder or the 
Trustee to exercise any right or remedy against any other guarantor of the 
Obligations; or (f) any change in the ownership of such Subsidiary Guarantor.

     Each Subsidiary Guarantor further agrees that its Subsidiary Guaranty 
herein constitutes a guarantee of payment, performance and compliance when 
due (and not a guarantee of collection) and waives any right to require that 
any resort be had by any Holder or the Trustee to any security held for 
payment of the Obligations.

     Except as expressly set forth in Sections 8.1(b), 10.2 and 10.6, the 
obligations of each Subsidiary Guarantor hereunder shall not be subject to 
any reduction, limitation, impairment or termination for any reason, 
including any claim of waiver, release, surrender, alteration or compromise, 
and shall not be subject to any defense of set off, counterclaim, recoupment 
or termination whatsoever or by reason of the invalidity, illegality or 
unenforceability of the Obligations or otherwise. Without limiting the 
generality of the foregoing, the obligations of each Subsidiary Guarantor 
herein shall not be discharged or impaired or otherwise affected by the 
failure of any Holder or the Trustee to assert any claim or demand or to 
enforce any remedy under this Indenture, the Notes or any other agreement, by 
any waiver of modification of any thereof, by any default, failure or delay, 
willful or otherwise, in the performance of the obligations, or by any other 
act or thing or omission or delay to do any other act or thing which may or 
might in any manner or to any extent vary the risk of such Subsidiary 
Guarantor or would otherwise operate as a discharge of such Subsidiary 
Guarantor as a matter of law or equity.

     Each Subsidiary Guarantor further agrees that its Guarantee herein shall 
continue to be effective or be reinstated, as the case may be, if at any time 
payment, or any part thereof, of principal of or interest on any Obligation 
is rescinded or must otherwise be restored by any Holder or the Trustee upon 
the bankruptcy or reorganization of the Issuers or otherwise. In furtherance 
of the foregoing and not in limitation of any other right which any Holder or 
the Trustee has at law or in equity against any Subsidiary Guarantor by 
virtue hereof, upon the failure of the Issuers to pay the principal of or 
interest on any Obligation when and as the same shall become due, whether at 
maturity, by acceleration, by redemption or otherwise, or to perform or 
comply with any other Obligation, each Subsidiary Guarantor hereby promises 
to and will, upon receipt of written demand


                                       67

<PAGE>

by the Trustee, forthwith pay, or cause to be paid, in cash to the Holders or 
the Trustee an amount equal to the sum of (i) the unpaid amount of such 
Obligations, (ii) accrued and unpaid interest on such Obligations (but only 
to the extent not prohibited by law) and (iii) all other monetary Obligations 
of the Issuers to the Holders and the Trustee.

     Each Subsidiary Guarantor agrees that, as between it, on the one hand, 
and the Holders and the Trustee, on the other hand, (x) the maturity of the 
Obligations Guaranteed hereby may be accelerated as provided in Article 6 for 
the purposes of such Subsidiary Guarantor's Subsidiary Guaranty herein, 
notwithstanding any stay, injunction or other prohibition preventing such 
acceleration in respect of any Obligations Guaranteed hereby, and (y) in the 
event of any declaration of acceleration of such obligations as provided in 
Article 6, such Obligations (whether or not due and payable) shall forthwith 
become due and payable by such Subsidiary Guarantor for the purposes of this 
Section.

     Each Subsidiary Guarantor may consolidate with or merge into or sell its 
assets to Issuers or another Subsidiary Guarantor without limitation. Each 
Subsidiary Guarantor may consolidate with or merge into or sell all or 
substantially all its assets to a Person other than Issuers or another 
Subsidiary Guarantor (whether or not affiliated with the Subsidiary 
Guarantor). Upon the sale or disposition (by merger or otherwise) of a 
Subsidiary Guarantor (or all Subsidiary or substantially all of its assets) 
to a Person (whether or not an Affiliate of the Subsidiary Guarantor) which 
is not a Subsidiary of Issuers, which sale or disposition is otherwise in 
compliance with this Indenture (including Section 4.6), such Subsidiary 
Guarantor shall be deemed released from all its obligations under this 
Indenture and its Subsidiary Guarantee and such Subsidiary Guarantee shall 
terminate; provided, however, that any such termination shall occur only to 
the extent that all obligations of such Subsidiary Guarantor under the Bank 
Facility and all of its Guarantees of, and under all of its pledges of assets 
or other security interests which secure, any other Indebtedness of the 
Issuers shall also terminate upon such release, sale or transfer.

     Each Subsidiary Guarantor also agrees to pay any and all costs and 
expenses (including reasonable attorneys' fees) incurred by the Trustee or 
any Holder in enforcing any rights under this Section.

SECTION 10.2      Limitation on Liability.

     Any term or provision of this Indenture to the contrary notwithstanding, 
the maximum, aggregate amount of the Obligations guaranteed hereunder by any 
Subsidiary Guarantor shall not exceed the maximum amount that can be hereby 
guaranteed without rendering this Indenture or the Guarantee, as they relate 
to such Subsidiary Guarantor, voidable under applicable law relating to 
fraudulent conveyance or fraudulent transfer or similar laws affecting the 
rights of creditors generally.

SECTION 10.3      Successors and Assigns.

     This Article 10 shall be binding upon each Subsidiary Guarantor and its 
successors and assigns and shall enure to the benefit of the successors and 
assigns of the Trustee and the Holders and, in the event of any transfer or 
assignment of rights by any Holder or the Trustee, the rights and privileges 
conferred upon that party in this Indenture and in the Notes shall 
automatically extend to and be vested in such transferee or assignee, all 
subject to the terms and conditions of this Indenture.

SECTION 10.4      No Waiver.

     Neither a failure nor a delay on the part of either the Trustee or the 
holders in exercising any right, power or privilege under this Article 10 
shall operate as a waiver thereof, nor shall a single or partial exercise 
thereof preclude any other or further exercise of any right, power or 
privilege. The rights, remedies and benefits of the Trustee and the Holders 
herein expressly specified are cumulative and not exclusive of any other 
rights, remedies or benefits which either may have under this Article 10 at 
law, in equity, by statute or otherwise.

SECTION 10.5      Modification.

     No modification, amendment or waiver of any provision of this Article 
10, nor the consent to any departure by any Subsidiary Guarantor therefrom, 
shall in any event be effective unless the same shall be in writing and 
signed by the Trustee, and then such waiver or consent shall be effective 
only in the specific instance and for the purpose for which given. No notice 
to or demand on any Subsidiary Guarantor in any case shall entitle such 
Subsidiary Guarantor to any other or further circumstances.

SECTION 10.6      Release of Subsidiary Guarantor.

     Upon the sale or other disposition (including by way of consolidation or 
merger) of all of the Capital Stock of such a Subsidiary Guarantor, the sale 
or disposition of all or substantially all the assets of such Subsidiary 
Guarantor (in each case other than to the Issuers or a Subsidiary Guarantor) 
or the designation of a Subsidiary Guarantor as an Unrestricted Subsidiary in 
each case in compliance with this Indenture, such Subsidiary Guarantor shall 
be deemed released from all obligations under this Article 10 without any 
further action required on the part of the Trustee or any Holder. At the 
request of the Issuers, the Trustee shall execute and deliver an appropriate 
instrument evidencing such release.

                                COLLATERAL AND SECURITY

SECTION 11.1      Escrow Agreement and Escrow Security Agreement.

     On the Issue Date, the Issuers shall (i) enter into the Escrow Agreement 
and the Escrow Security Agreement and comply with the terms and provisions 
thereof, (ii) deposit into the Interest Escrow Account such amount in cash 
from the proceeds of the Offering as will be sufficient to provide for 
payment in full of the first two scheduled interest payments due on the Notes 
and (iii) deposit the balance into the Construction Escrow Account. On the 
first date on which the amount deposited into the Interest Escrow Account is 
invested in Temporary Cash Investments, such Temporary Cash Investments shall 
be in an amount sufficient upon receipt of scheduled interest and/or 
principal payments of such Collateral to provide for payment in full of the 
first two scheduled interest payments due on the Notes. The Issuers shall 
grant a first priority security interest in the Collateral to the Collateral 
Agent for the benefit of the Holders and the Collateral shall be held by the 
Collateral Agent in the Escrow Accounts pending disposition pursuant to the 
Escrow Agreement.

     In the event the Registered Exchange Offer is not consummated, and the 
Registration Statement is not declared effective within 120 days (or if the 
120th day is not a Business Day, the first Business Day thereafter) after the 
Issue Date of the Notes, and the interest rate on the Notes is increased as 
required by the Registration Rights Agreement, the Issuers shall deposit into 
the Interest Escrow Account, on or before the next succeeding scheduled 
interest payment date, additional cash in such amount as will be sufficient 
upon receipt of scheduled interest and/or principal payments of all 
Collateral thereafter held in the Interest Escrow Account, to provide payment 
for the first two scheduled interest payments due on the Notes (assuming the 
Additional Interest remains in effect for the entire period). The additional 
Collateral shall be subject to the security interest granted by the Issuers 
to the Collateral Agent for the benefit of the Holders and shall be held by 
the Collateral Agent in the Interest Escrow Account.

     Each Holder, by its acceptance of a Note, consents and agrees to the 
terms of the Escrow Agreement and the Escrow Security Agreement (including, 
without limitation, the provisions providing for foreclosure and release of 
the Collateral) as the same may be in effect or may be amended from time to 
time in accordance with its terms, and authorizes and directs the Trustee to 
enter into the Escrow Agreement and the Escrow Security Agreement and to 
perform its respective obligations and exercise its respective rights 
thereunder in accordance therewith. The Issuers will do or cause to be done 
all such acts and things as may be necessary or proper, or as may be required 
by the provisions of the Escrow Agreement and the Escrow Security Agreement, 
to assure and confirm to the Trustee the security interest in the Collateral 
contemplated hereby or by the Escrow Agreement or the Escrow Security 
Agreement or any part thereof, as from time to time constituted, so as to 
render the same available for the security and benefit of this Indenture and 
of the Notes secured hereby, according to the intent and purposes herein 
expressed. The Issuers shall take, or shall cause to be taken, upon request 
of the Trustee, any and all actions reasonably required to cause the


                                       70
<PAGE>

Escrow Agreement and the Escrow Security Agreement to create and maintain, as 
security for the obligations of the Issuers under this Indenture and the 
Notes, valid and enforceable first priority liens in and on all the 
Collateral, in favor of the Trustee, superior to and prior to the rights of 
third Persons and subject to no other Liens.

SECTION 11.2      Recording and Opinions.

          (a) The Issuers shall furnish to the Trustee simultaneously with 
the execution and delivery of this Indenture an Opinion of Counsel either (i) 
stating that in the opinion of such counsel all action has been taken with 
respect to the recording, registering and filing of this Indenture, financing 
statements or other instruments necessary to make effective the Liens 
intended to be created by the Escrow Security Agreement and reciting the 
details of such action, except for the filing of any necessary UCC-1 
financing statements, or (ii) stating that in the opinion of such counsel no 
such action is necessary to make such Liens effective.

          (b) The Issuers shall furnish to the Escrow Agent and the Trustee 
on April 29, 1998 (unless on such date the balance of the Interest Escrow 
Account and the Construction Escrow Account shall be zero) an Opinion of 
Counsel, dated as of such date, either (i) stating that, except for the 
filing of any necessary UCC-1 financing statements, (A) in the opinion of 
such counsel, action has been taken with respect to the recording, 
registering, filing, re-recording, re-registering and refiling of all 
supplemental indentures, financing statements, continuation statements or 
other instruments of further assurance as are necessary to maintain the Liens 
of the Escrow Security Agreement and reciting the details of such action or 
referring to prior Opinions of Counsel in which such details are given and 
(B) based on relevant laws as in effect on the date of such Opinion of 
Counsel, all financing statements and continuation statements have been 
executed and filed that are necessary as of such date and during the 
succeeding 12 months fully to preserve and protect, to the extent such 
protection and preservation are possible by filing, the rights of the Holders 
of Notes and the Trustee hereunder and under each of the Escrow Agreement and 
the Escrow Security Agreement with respect to the security interests in the 
Collateral or (ii) stating that, in the opinion of such counsel, no such 
action is necessary to maintain such Liens and assignments.

SECTION 11.3      Release of Collateral.

          (a) Subject to subsections (b), (c) and (d) of this Section 11.3, 
Collateral may be released from the Liens and security interests created by 
the Escrow Security Agreement only in accordance with the provisions of the 
Escrow Agreement and the Escrow Security Agreement.

          (b) Except to the extent that any Lien on proceeds of Collateral is 
automatically released by operation of Section 9-306 of the Uniform 
Commercial Code or other similar law, no Collateral shall be released from 
the Liens and security interests created by the Escrow Security Agreement 
pursuant to the provisions of the Escrow Security Agreement, other than to 
the Holders pursuant to the terms thereof, unless there shall have been 
delivered to the Trustee the certificate required by Section 11.3(d) and 
Section 11.4.

                                       71

<PAGE>

          (c) At any time when an Event of Default shall have occurred and be 
continuing and the maturity of the Notes shall have been accelerated (whether 
by declaration or otherwise), no Collateral shall be released pursuant to the 
provisions of the Escrow Security Agreement, and no release of Collateral in 
contravention of this Section 11.3(c) shall be effective as against the 
Holders of Notes, except for the disbursement of all Available Funds (as 
defined in the Escrow Agreement) and other Collateral to the Trustee pursuant 
to Section 11 of the Escrow Agreement.

          (d) The release of any Collateral from the Liens and security 
interests created by this Indenture and the Escrow Security Agreement shall 
not be deemed to impair the security under this Indenture in contravention of 
the provisions hereof if and to the extent the Collateral is released 
pursuant to the terms hereof or pursuant to the terms of the Escrow Agreement 
and the Escrow Security Agreement. To the extent applicable, the Issuers 
shall cause TIA Section 314(d) relating to the release of property or Notes 
from the Liens and security interests of the Escrow Security Agreement to be 
complied with. Any certificate or opinion required by TIA Section 314(d) may 
be made by an Officer of each of the Issuers except in cases where TIA 
Section 314(d) requires that such certificate or opinion be made by an 
independent Person, which Person shall be an independent appraiser or other 
expert selected or approved by the Trustee in the exercise of reasonable care.

SECTION 11.4      Certificates of the Issuers.

     The Issuers shall furnish to the Trustee, prior to any proposed release 
of Collateral other than pursuant to the express terms of the Escrow 
Agreement, (i) all documents required by TIA Section 314(d) and (ii) an 
Opinion of Counsel, which may be rendered by internal counsel to either of 
the Issuers, to the effect that such accompanying documents constitute all 
documents required by TIA Section 314(d). The Trustee may, to the extent 
permitted by Section 7.1 and Section 7.2, accept as conclusive evidence of 
compliance with the foregoing provisions the appropriate statements contained 
in such documents and such Opinion of Counsel.

SECTION 11.5      Authorization of Actions to Be Taken by the Trustee 
Under the Escrow Agreement and the Escrow Security Agreement.

     Subject to the provisions of Section 7.1 and Section 7.2, the Trustee 
may, without the consent of the Holders of Notes, on behalf of the Holders of 
Notes, take all actions it deems necessary or appropriate in order to (a) 
enforce any of the terms of each of the Escrow Agreement and the Escrow 
Security Agreement and (b) collect and receive any and all amounts payable in 
respect of the obligations of the Issuers hereunder. The Trustee shall have 
power to institute and maintain such suits and proceedings as it may deem 
expedient to prevent any impairment of the Collateral by any acts that may be 
unlawful or in violation of the Escrow Agreement, the Escrow Security 
Agreement or this Indenture, and such suits and proceedings as the Trustee 
may deem expedient to preserve or protect its interests and the interests of 
the Holders of Notes in the Collateral (including power to institute and 
maintain suits or proceedings to restrain the enforcement of or compliance 
with any legislative or other governmental enactment, rule or order that may 
be unconstitutional or otherwise

                                       72

invalid if the enforcement of, or compliance with, such enactment, rule or 
order would impair the security interest hereunder or be prejudicial to the 
interests of the Holders of Notes or of the Trustee).

                  Escrow Agreement.

distributions of such funds to the Holders of Notes according to the 
provisions of this Indenture.

SECTION 11.7      Termination of Security Interest.

     Upon the earliest to occur of (i) the date upon which the balance in the 
Interest Escrow Account shall have been reduced to zero, (ii) legal 
defeasance pursuant to Section 8.1(b), (iii) covenant defeasance pursuant to 
Section 8.1(b) or (iv) the date upon which the first two semiannual interest 
payments have been made, the Trustee shall, at the written request of each of 
the Issuers, release the Liens on the Interest Escrow Account pursuant to 
this Indenture, the Escrow Agreement and the Escrow Security Agreement upon 
the Issuers' compliance with the provisions of the TIA pertaining to release 
of collateral.

     Upon the earliest to occur of (i) the date upon which the balance in the 
Construction Escrow Account shall have been reduced to zero, (ii) legal 
defeasance pursuant to Section 8.1(b), (iii) covenant defeasance pursuant to 
Section 8.1(b) or (iv) the full and final payment and performance of all the 
Obligations and Construction Expenses (as defined in the Escrow Agreement), 
the Trustee shall, at the written request of each of the Issuers, release the 
Liens on the Construction Escrow Account pursuant to this Indenture, the 
Escrow Agreement and the Escrow Security Agreement upon the Issuers' 
compliance with the provisions of the TIA pertaining to release of collateral.

Notes have concurred in any direction, waiver or consent, Notes owned by the 
Issuers or by any Person directly or indirectly controlling or controlled by 
or under direct or indirect common control with the Issuers shall be 
disregarded and deemed not to be outstanding, except that, for the purpose of 
determining whether the Trustee shall be protected in relying on any such 
direction, waiver or consent, only Notes which the Trustee actually knows are

exchange of Global Notes or beneficial interests therein shall be effected

applicable restrictions on transfer set forth herein, if any) and the

in a Global Note shall deliver to the Registrar a written order given in 
accordance with the Depositary's procedures containing information regarding 
the participant account of the Depositary to credited with a beneficial 
interest in the Global Note. The Registrar shall, in accordance with such 
instructions instruct the Depositary to credit to the account of the Person

interest in the Global Note being transferred.

     (other than the provisions set forth in Section 2.4), a Global Note may

     or Section 2.8 of the Indenture, prior to the consummation of a 
     Registered Exchange Offer or the effectiveness of a Shelf Registration 
     Statement with respect to such Notes, such Notes may be exchanged only 
     in accordance with such procedures as are substantially consistent with 
     the provisions of this Section 2.3 (including the certification 
     requirements set forth on the reverse of the Initial Notes intended to 
     ensure that such transfers comply with Rule 144A or Regulation S, as the 
     case may be) and such other procedures as may from time to time be

     WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM
     REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933
     (THE "SECURITIES ACT"), AND THIS SECURITY MAY NOT BE 

                                        4

<PAGE>

     OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE
     ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION
     THEREFROM. EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED
     THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE
     EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES
     ACT PROVIDED BY RULE 144A.

     THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE
     ISSUER THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED
     OR OTHERWISE TRANSFERRED ONLY (i) INSIDE THE UNITED STATES TO
     A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A "QUALIFIED
     INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE
     SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF
     RULE 144A, (ii) OUTSIDE THE UNITED STATES IN AN OFFSHORE
     TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES
     ACT, (iii) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER
     THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF
     AVAILABLE), OR (iv) PURSUANT TO AN EFFECTIVE REGISTRATION
     STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (i)
     THROUGH (iv) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS
     OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL,
     AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY
     PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS
     REFERRED TO IN (A) ABOVE."

               (ii) Upon any sale or transfer of a Transfer Restricted Note 
     (including any Transfer Restricted Note represented by a Global Note) 
     pursuant to Rule 144 under the Securities Act, in the case of any 
     Transfer Restricted Note that is represented by a Global Note, the 
     Registrar shall permit the Holder thereof to exchange such Transfer 
     Restricted Note for a certificated Note that does not bear the legend 
     set forth above and rescind any restriction on the transfer of such 
     Transfer Restricted Note, if the Holder certifies in writing to the 
     Registrar that its request for such exchange was made in reliance on 
     Rule 144 (such certification to be in the form set forth on the reverse 
     of the Note).

               (iii) After a transfer of any Initial Notes or Private 
     Exchange Notes during the period of the effectiveness of a Shelf 
     Registration Statement with respect to such Initial Notes or Private 
     Exchange Notes, as the case may be, all requirements pertaining to 
     legends on such Initial Note or such Private Exchange Note will cease to 
     apply, the requirements 

                                        5
<PAGE>

     requiring any such Initial Note or such Private Exchange Note issued to 
     certain Holders be issued in global form will cease to apply, and a 
     certificated Initial Note or Private Exchange Note without legends will 
     be available to the transferee of the Holder of such Initial Notes or 
     Private Exchange Notes upon exchange of such transferring Holder's 
     certificated Initial Note or Private Exchange Note or directions to 
     transfer such Holder's interest in the Global Note, as applicable.

               (iv) Upon the consummation of a Registered Exchange Offer with 
     respect to the Initial Notes pursuant to which Holders of such Initial 
     Notes are offered Exchange Notes in exchange for their Initial Notes, 
     all requirements pertaining to such Initial Notes that Initial Notes 
     issued to certain Holders be issued in global form will cease to apply 
     and certificated Initial Notes with the restricted securities legend set 
     forth in Exhibit 1 hereto will be available to Holders of such Initial 
     Notes that do not exchange their Initial Notes, and Exchange Notes in 
     certificated or global form will be available to Holders that exchange 
     such Initial Notes in such Registered Exchange Offer.

               (v) Upon the consummation of a Private Exchange with respect 
     to the Initial Notes pursuant to which Holders of such Initial Notes are 
     offered Private Exchange Notes in exchange for their Initial Notes, all 
     requirements pertaining to such Initial Notes that Initial Notes issued 
     to certain Holders be issued in global form will still apply, and 
     Private Exchange Notes in global form with the Restricted Notes Legend 
     set forth in Exhibit I hereto will be available to Holders that exchange 
     such Initial Notes in such Private Exchange.

     (c) Cancellation or Adjustment of Global Note. At such time as all 
beneficial interests in a Global Note have either been exchanged for 
certificated Notes, redeemed, repurchased or canceled, such Global Note shall 
be returned to the Depository for cancellation or retained and canceled by 
the Trustee. At any time prior to such cancellation, if any beneficial 
interest in a Global Note is exchanged for certificated Notes, redeemed, 
repurchased or canceled, the principal amount of Notes represented by such 
Global Note shall be reduced and an adjustment shall be made on the books and 
records of the Trustee (if it is then the Notes Custodian for such Global 
Note) with respect to such Global Note, by the Trustee or the Notes 
Custodian, to reflect such reduction.

     (d) Obligations with Respect to Transfers and Exchanges of Notes.

               (i) To permit registrations of transfers and exchanges, the 
     Issuers shall execute and the Trustee shall authenticate certificated 
     Notes and Global Notes at the Registrar's or co-registrar's request. No 
     service charge shall be made for any registration of transfer or 
     exchange, but the Issuers may require payment of a sum sufficient to 
     cover any transfer tax, assessments, or similar governmental charge 
     payable in connection therewith (other than any such transfer taxes, 
     assessments or similar governmental charge payable upon exchange or 
     transfer pursuant to Sections 3.6, 6.11 and Section 9.5 of the 
     Indenture).

                                        6

<PAGE>

               (ii) The Registrar or co-registrar shall not be required to 
     register the transfer of or exchange of (a) any certificated Note 
     selected for redemption in whole or in part pursuant to Article 3 of the 
     Indenture, except the unredeemed portion of any certificated Note being 
     redeemed in part, or (b) any Note for a period beginning 15 Business 
     Days before the mailing of a notice of an offer to repurchase or redeem 
     Notes or 15 Business Days before an interest payment date.

               (iii) Prior to the due presentation for registration of 
     transfer of any Note, the Issuers, the Trustee, the Paying Agent, the 
     Registrar or any co-registrar may deem and treat the person in whose 
     name a Note is registered as the absolute owner of such Note for the 
     purpose of receiving payment of principal of and interest on such Note 
     and for all other purposes whatsoever, whether or not such Note is 
     overdue, and none of the Issuers, the Trustee, the Paying Agent, the 
     Registrar or any co-registrar shall be affected by notice to the 
     contrary.

               (iv) All Notes issued upon any transfer or exchange pursuant 
     to the terms of the Indenture shall evidence the same debt and shall be 
     entitled to the same benefits under the Indenture as the Notes 
     surrendered upon such transfer or exchange.

     (e)      No Obligation of the Trustee.

               (i) The Trustee shall have no responsibility or obligation to 
     any beneficial owner of a Global Note, a member of, or a participant in 
     the Depository or other Person with respect to the accuracy of the 
     records of the Depository or its nominee or of any participant or member 
     thereof, with respect to any ownership interest in the Notes or with 
     respect to the delivery to any participant, member, beneficial owner or 
     other Person (other than the Depository) of any notice (including any 
     notice of redemption) or the payment of any amount, under or with 
     respect to such Notes. All notices and communications to be given to the 
     Holders and all payments to be made to Holders under the Notes shall be 
     given or made only to or upon the order of the registered Holders (which 
     shall be the Depository or its nominee in the case of a Global Note). 
     The rights of beneficial owners in any Global Note shall be exercised 
     only through the Depository subject to the applicable rules and 
     procedures of the Depository. The Trustee may rely and shall be fully 
     protected in relying upon information furnished by the Depository with 
     respect to its members, participants and any beneficial owners.

               (ii) The Trustee shall have no obligation or duty to monitor, 
     determine or inquire as to compliance with any restrictions on transfer 
     imposed under the Indenture or under applicable law with respect to any 
     transfer of any interest in any Note (including any transfers between or 
     among Depository participants, members or beneficial owners in any 
     Global Note) other than to require delivery of such certificates and 
     other documentation or evidence as are expressly required by, and to do 
     so if and when expressly required by,

                                        7

     the terms of the Indenture, and to examine the same to determine 
     substantial compliance as to form with the express requirements hereof.

     2.4.     Certificated Notes.

          (a) A Global Note deposited with the Depository or with the Trustee 
as custodian for the Depository pursuant to Section 2.1 shall be transferred 
to the beneficial owners thereof in the form of certificated Notes in an 
aggregate principal amount equal to the principal amount of such Global Note, 
in exchange for such Global Note, only if such transfer complies with Section 
2.3 and (i) the Depository notifies the Issuers that it is unwilling or 
unable to continue as Depository for such Global Note or if at any time such 
Depository ceases to be a "clearing agency" registered under the Exchange Act

such notice, or (ii) the Issuers, in their sole discretion, notify the 
Trustee in writing that they elects to cause the issuance of certificated

          (b) Any Global Note that is transferable to the beneficial owners

Global Note shall, except as otherwise provided by Section 2.3(d), bear the 
restricted securities legend set forth in Exhibit 1 hereto.

          (c) Subject to the provisions of Section 2.4(b), the registered

                   [FORM OF REVERSE SIDE OF INITIAL SECURITY]

                            10% SENIOR NOTE DUE 2008

         1.       Interest

         CHILES OFFSHORE LLC, a Delaware limited liability company, and CHILES
OFFSHORE FINANCE CORP., a Delaware corporation (such entities, and their
successors and assigns under the Indenture hereinafter referred to, and each
other entity which is required to become one of the Issuers pursuant to the
Indenture, and its successors and assigns under the Indenture, being herein
called the "Issuers"), jointly and severally promise to pay interest on the
principal amount of this Note at the rate per annum shown above. The Issuers
will pay interest semiannually on May 1 and November 1 of each year, commencing
November 1, 1998. Interest on the Notes will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from April 29,
1998. Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Issuers shall pay interest on overdue principal at the rate of 1.0%
per annum in excess of the rate borne by the Notes, and it shall pay interest on
overdue installments of interest at 1.0% per annum in excess of such rate to the
extent lawful.

         2.       Method of Payment

         The Issuers will pay interest on the Notes (except defaulted interest)
to the Persons who are registered holders of Notes at the close of business on
the record date immediately preceding the interest payment date even if Notes
are canceled after the record date and on or before the interest payment date.
Holders must surrender Notes to a Paying Agent to collect principal payments.
The Issuers will pay principal and interest in money of the United States that
at the time of payment is legal tender for payment of public and private debts.
Payments in respect of the Notes represented by a Global Note (including
principal, premium and interest) will be made by wire transfer of immediately
available funds to the accounts specified by The Depository Trust Company. The
Issuers will make all payments in respect of a certificated Note (including
principal, premium and interest) by mailing a check to the registered address of
each Holder thereof; provided, however, that payments on a certificated Note
will be made by wire transfer to a U.S. dollar account maintained by the payee
with a bank in the United States if such Holder elects payment by wire transfer
by giving written notice to the Trustee or the Paying Agent to such effect
designating such account no later than 30 days immediately preceding the
relevant due date for payment (or such other date as the Trustee may accept in
its discretion).

         3.       Paying Agent and Registrar

         Initially, U.S. Bank Trust National Association, a national banking
corporation ("Trustee"), will act as Paying Agent and Registrar. The Issuers may
appoint and change any Paying Agent, Registrar or co-Registrar without notice.
The Issuers may act as Paying Agent, Registrar, co-Registrar or transfer agent.

                                       A-5


<PAGE>



         4.       Indenture

         The Issuers issued the Notes under an Indenture dated as of April 29,
1998 (the "Indenture"), among the Issuers, the Subsidiary Guarantors named
therein and the Trustee. The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. Section 77aa77bbbb) as in effect on the date of
the Indenture (the "TIA"). Terms defined in the Indenture and not defined herein
have the meanings ascribed thereto in the Indenture. The Notes are subject to
all such terms, and Noteholders are referred to the Indenture and the TIA for a
statement of those terms. Any conflict between this Note and the Indenture will
be governed by the Indenture.

         The Notes are general senior obligations of the Issuers limited to $110
million aggregate principal amount. The Indenture imposes certain limitations on
the Incurrence of Indebtedness by the Issuers and their Restricted Subsidiaries,
the existence of liens, the payment of dividends on, and redemption of, the
Capital Stock of the Issuers and their Subsidiaries, restricted payments, the
sale or transfer of assets and Subsidiary stock, the issuance or sale of Capital
Stock of Restricted Subsidiaries, sale and leaseback transactions, the
investments of the Issuers and their Restricted Subsidiaries, consolidations,
mergers and transfers of all or substantially all the assets of the Issuers, and
transactions with Affiliates. In addition, the Indenture limits the ability of
the Issuers and certain of their Subsidiaries to restrict distributions and
dividends from Restricted Subsidiaries.

         5.       Optional Redemption

         Except as set forth in the next paragraph, the Notes may not be
redeemed prior to May 1, 2003. Thereafter, the Issuers may redeem as provided
in, and subject to the terms of, the Indenture the Notes in whole or in part, at
any time or from time to time, at the following redemption prices (expressed in
percentages of principal amount), plus accrued interest to the redemption date
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date) if redeemed during
the 12-month period commencing on May 1 of the years set forth below:

<TABLE>
<CAPTION>

                               Period                     Percentage
                  ------------------------------      -------------------
                <S>                                  <C>    
                  2003..........................            105.00%
                  2004..........................            103.33%
                  2005..........................            101.67%
                  2006 and thereafter...........            100.00%
</TABLE>

         In addition, at any time and from time to time prior to May 1, 2001,
the Issuers may redeem in the aggregate up to 35% of the principal amount of the
Notes with the proceeds of one or more Public Equity Offerings, at a redemption
price (expressed as a percentage of principal amount) of 110% plus accrued
interest to the redemption date (subject to the right of Holders of record on
the relevant record date to receive interest due on the relevant interest
payment date) as provided in,

                                       A-6


<PAGE>



and subject to the terms of, the Indenture; provided, however, that at least
$71.5 million aggregate principal amount of the Notes must remain outstanding
after each such redemption and, provided further, that such redemption shall
occur within 90 days following the closing of such Public Equity Offering.

         6.       Notice of Redemption

         Notice of redemption will be mailed by first-class mail at least 30
days but not more than 60 days before the redemption date to each Holder of
Notes to be redeemed at his registered address. Notes in denominations larger
than $1,000 may be redeemed in part but only in whole multiples of $1,000. If
money sufficient to pay the redemption price of and accrued interest on all
Notes (or portions thereof) to be redeemed on the redemption date is deposited
with the Paying Agent on or before the redemption date and certain other
conditions are satisfied, on and after such date interest ceases to accrue on
such Notes (or such portions thereof) called for redemption. If a notice or
communication is sent in the manner provided in the Indenture, it is duly given,
whether or not the addressee receives it. Failure to send a notice or
communication to a Noteholder or any defect in it shall not affect its
sufficiency with respect to other Noteholders. In addition, in the event of
certain Asset Dispositions, the Issuers will be required to make an offer to
purchase Notes at a purchase price of 100% of their principal amount plus
accrued interest to the date of purchase (subject to the rights of Holders of
record on the relevant record date to receive interest due on the relevant
interest payment date) as provided in, and subject to the terms of, the
Indenture.

         7.       Change of Control

         Upon a Change of Control, each Holder of Notes will have the right to
require the Issuers to repurchase all or any part of the Notes of such Holder at
a repurchase price in cash equal to 101% of the principal amount of the Notes to
be repurchased plus accrued and unpaid interest to the date of repurchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date) as provided in, and
subject to the terms of, the Indenture.

         8.       Contract Termination

         In the event that a Construction Contract is terminated prior to
delivery of the Rig, each Holder will have the right to require the Issuers to
purchase the Allocated Principal Amount of such Holder's Notes for such Rig at a
purchase price equal to 101% of the principal amount thereof, plus accrued and
unpaid interest to the date of purchase.

         9.       Event of Loss of a Rig

         Upon the occurrence of an Event of Loss of a Rig after the delivery of
such Rig, the Issuers will be required to apply the insurance and other proceeds
either to repay indebtedness outstanding under the Bank Facility or other
secured debt (and permanently reduce the commitments thereunder) or to acquire a
Qualified Substitute Rig, and to apply the balance to purchase the

                                       A-7


<PAGE>

Allocated Principal Amount of Notes tendered by Holders at a purchase price
equal to 101% of the principal amount thereof, plus accrued and unpaid interest
to the date of purchase.

         10.      Denominations; Transfer; Exchange

         The Notes are in registered form without coupons in denominations of
$1,000 and whole multiples of $1,000. A Holder may transfer or exchange Notes in
accordance with the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements or transfer documents and to pay any
taxes and fees required by law or permitted by the Indenture, including any
transfer tax or other similar governmental charge payable in connection
therewith. The Registrar need not register the transfer of or exchange any Notes
selected for redemption (except, in the case of a Note to be redeemed in part,
the portion of the Note not to be redeemed) or any Notes for a period of 15 days
before a selection of Notes to be redeemed or 15 days before an interest payment
date.

         11.      Persons Deemed Owners

         The registered Holder of this Note may be treated as the owner of it
for all purposes.

         12.      Unclaimed Money

         If money for the payment of principal or interest remains unclaimed for
two years, the Trustee or Paying Agent shall pay the money back to the Issuers
at their written request unless an applicable abandoned property law designates
another Person. After any such payment, Holders entitled to the money must look
only to the Issuers and not to the Trustee for payment.

         13.      Discharge and Defeasance

         Subject to certain conditions, the Issuers at any time may terminate
some or all of their obligations under the Notes and the Indenture if the
Issuers deposit with the Trustee money or U.S. Government Obligations for the
payment of principal and interest on the Notes to redemption or maturity, as the
case may be.

         14.      Amendment, Waiver

         Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Notes may be amended with the consent of the Holders of at
least a majority in principal amount outstanding of the Notes and (ii) any past
default or compliance with any provision may be waived with the consent of the
Holders of a majority in principal amount outstanding of the Notes. Subject to
certain exceptions set forth in the Indenture, without the consent of any
Noteholder, the Issuers and the Trustee may amend the Indenture or the Notes to
cure any ambiguity, omission, defect or inconsistency, to comply with Article 5
of the Indenture, to provide for uncertificated Notes in addition to or in place
of certificated Notes, to add guarantees with respect to the Notes, to secure

                                       A-8


<PAGE>



the Notes, to add additional covenants or surrender rights and powers conferred
on the Issuers, to make any change that does not adversely affect the rights of
any Noteholder or to comply with any request of the SEC in connection with
qualifying the Indenture under the TIA.

         15.      Defaults and Remedies

         Under the Indenture, Events of Default include (i) default for 30 days
in payment of interest on the Notes; (ii) default in payment of principal on any
Note when due at its Stated Maturity, upon redemption pursuant to paragraphs 5
or 6 above, upon required repurchase, upon acceleration or otherwise, (iii)
failure by the Issuers to comply with Article 5 of the Indenture; (iv) failure
by the Issuers to comply for 30 days after the notice specified in the paragraph
below with certain covenants (other than a failure to purchase Notes when
required upon the occurrence of certain events) of the Indenture; (v) failure by
the Issuers to comply for 60 days after the Issuers receive the notice specified
in the paragraph below with any of their other agreements in the Indenture
(other than those referred to in (i), (ii), (iii) or (iv) above); (vi) failure
by the Issuers or any Significant Subsidiary to pay any Indebtedness within any
applicable grace period after final maturity or acceleration by the Holders
thereof because of a default and the total amount of such Indebtedness unpaid or
accelerated exceeds $10 million; (vii) certain events of bankruptcy, insolvency
or reorganization of the Issuers or any Significant Subsidiary; (viii) the
rendering of any judgments or decrees for the payment of money in excess of $10
million, or its foreign equivalent at the time, is entered against the Issuers
or any Significant Subsidiary if such judgment or decree remains outstanding for
a period of 60 days following entry of such judgment and is not discharged,
bonded, waived or stayed within 30 days after notice thereof, (ix) a Subsidiary
Guarantee ceases to be in full force and effect (other than in accordance with
the terms of such Subsidiary Guarantee or the Indenture) or a Subsidiary
Guarantor denies or disaffirm its obligations under its Subsidiary Guarantee,
and (x) the security interest under the Escrow Security Agreement between the
Issuers and U.S. Bank Trust National Association, dated April 29, 1998 (the
"Escrow Security Agreement") shall, at any time, cease to be in full force and
effect for any reason (other than by operation of the provisions of the
Indenture and the Escrow Security Agreement), or any security interest created
thereunder shall be declared invalid or unenforceable, or the Issuers or any
Restricted Subsidiary shall assert, in any pleading in any court of competent
jurisdiction that any such security interest is invalid or unenforceable.

         A Default under clause (iv) or (v) of Section 6.1 of the Indenture will
not constitute an Event of Default until the Trustee or the Holders of at least
25% in aggregate principal amount of the outstanding Notes notify the Issuers of
the Default and the Issuers do not cure such Default within the time specified
after receipt of such notice. Such notice must specify the Default, demand that
it be remedied and state that such notice is a "Notice of Default".

         If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Notes then outstanding may
declare all the Notes to be due and payable. Certain events of bankruptcy or
insolvency are Events of Default which will result in the Notes being due and
payable immediately upon the occurrence of such Events of Default.

                                       A-9


<PAGE>



         Noteholders may not enforce the Indenture or the Notes except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Notes unless it receives reasonable indemnity or security. Subject to
certain limitations, Holders of a majority in principal amount of the Notes may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from the Noteholders notice of any continuing Default (except a Default
in payment of principal or interest) if it determines that withholding notice is
not opposed to the interests of the Holders.

         16.      Guarantee and Security

         The obligations of the Issuers pursuant to the Indenture and the Notes,
including the repurchase obligations under the Indenture, will be

         1.       Interest

         CHILES OFFSHORE LLC, a Delaware limited liability company, and CHILES

successors and assigns under the Indenture hereinafter referred to, and each
other entity which is required to become one of the Issuers pursuant to the

called the "Issuers"), jointly and severally promise to pay interest on the
principal amount of this Note at the rate per annum shown above. The Issuers

which interest has been paid or, if no interest has been paid, from, April 29,

overdue installments of interest at 1.0% per annum in excess of such rate to the
extent lawful.

         2.       Method of Payment

         The Issuers will pay interest on the Notes (except defaulted interest)
to the Persons who are registered holders of Notes at the close of business on
the record date immediately preceding the interest payment date even if Notes

available funds to the accounts specified by The Depository Trust Company. The
Issuers will make all payments in respect of a certificated Note (including
principal, premium and interest) by mailing a check to the registered address of
each Holder thereof; provided, however, that payments on a certificated Note
will be made by wire transfer to a U.S. dollar account maintained by the payee
with a bank in the United States if such Holder elects payment by wire transfer
by giving written notice to the Trustee or the Paying Agent to such effect
designating such account no later than 30 days immediately preceding the
relevant due date for payment (or such other date as the Trustee may accept in
its discretion).

         3.       Paying Agent and Registrar

         4.       Indenture

         The Issuers issued the Notes under an Indenture dated as of April 29,
1998 (the "Indenture"), among the Issuers, the Subsidiary Guarantors named
therein and the Trustee. The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. Section 77aa77bbbb) as in effect on the date of
the Indenture (the "TIA"). Terms defined in the Indenture and not defined herein
have the meanings ascribed thereto in the Indenture. The Notes are subject to
all such terms, and Noteholders are referred to the Indenture and the TIA for a
statement of those terms. Any conflict between this Note and the Indenture will
be governed by the Indenture.

         The Notes are general senior obligations of the Issuers limited to $110
million aggregate principal amount. The Indenture imposes certain limitations on
the Incurrence of Indebtedness by the Issuers and their Restricted Subsidiaries,
the existence of liens, the payment of dividends on, and redemption of, the
Capital Stock of the Issuers and their Subsidiaries, restricted payments, the
sale or transfer of assets and Subsidiary stock, the issuance or sale of Capital
Stock of Restricted Subsidiaries, sale and leaseback transactions, the
investments of the Issuers and their Restricted Subsidiaries, consolidations,
mergers and transfers of all or substantially all the assets of the Issuers, and
transactions with Affiliates. In addition, the Indenture limits the ability of
the Issuers and certain of their Subsidiaries to restrict distributions and
dividends from Restricted Subsidiaries.

         5.       Optional Redemption

         Except as set forth in the next paragraph, the Notes may not be
redeemed prior to May 1, 2003. Thereafter, the Issuers may redeem as provided
in, and subject to the terms of, the Indenture the Notes in whole or in part, at
any time or from time to time, at the following redemption prices (expressed in
percentages of principal amount), plus accrued interest to the redemption date
(subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date) if redeemed during
the 12-month period commencing on May 1 of the years set forth below:

Notes with the proceeds of one or more Public Equity Offerings, at a redemption
price (expressed as a percentage of principal amount) of 110% plus accrued
interest to the redemption date (subject to the right of Holders of record on
the relevant record date to receive interest due on the relevant interest
payment date) as provided in,

         Notice of redemption will be mailed by first-class mail at least 30
days but not more than 60 days before the redemption date to each Holder of

Notes (or portions thereof) to be redeemed on the redemption date is deposited
with the Paying Agent on or before the redemption date and certain other
conditions are satisfied, on and after such date interest ceases to accrue on
such Notes (or such portions thereof) called for redemption. If a notice or
communication is sent in the manner provided in the Indenture, it is duly given,

communication to a Noteholder or any defect in it shall not affect its
sufficiency with respect to other Noteholders. In addition, in the event of
certain Asset Dispositions, the Issuers will be required to make an offer to
purchase Notes at a purchase price of 100% of their principal amount plus
accrued interest to the date of purchase (subject to the rights of Holders of

be repurchased plus accrued and unpaid interest to the date of repurchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date) as provided in, and
subject to the terms of, the Indenture.

         8.       Contract Termination

         In the event that a Construction Contract is terminated prior to
delivery of the Rig, each Holder will have the right to require the Issuers to
purchase the Allocated Principal Amount of such Holder's Notes for such Rig at a
purchase price equal to 101% of the principal amount thereof, plus accrued and
unpaid interest to the date of purchase.

         9.       Event of Loss of a Rig

         Upon the occurrence of an Event of Loss of a Rig after the delivery of
such Rig, the Issuers will be required to apply the insurance and other proceeds
either to repay indebtedness outstanding under the Bank Facility or other
secured debt (and permanently reduce the commitments thereunder) or to acquire a
Qualified Substitute Rig, and to apply the balance to purchase the


                                       B-6


<PAGE>



Allocated Principal Amount of Notes tendered by Holders at a purchase price

transfer tax or other similar governmental charge payable in connection
therewith. The Registrar need not register the transfer of or exchange any Notes

the portion of the Note not to be redeemed) or any Notes for a period of 15 days
before a selection of Notes to be redeemed or 15 days before an interest payment
date interest payment date.

         11.      Persons Deemed Owners

         The registered Holder of this Note may be treated as the owner of it
for all purposes.

         12.      Unclaimed Money

         If money for the payment of principal or interest remains unclaimed for
two years, the Trustee or Paying Agent shall pay the money back to the Issuers
at their written request unless an applicable abandoned property law designates
another Person. After any such payment, Holders entitled to the money must look
only to the Issuers and not to the Trustee for payment.

         13.      Discharge and Defeasance

         Subject to certain conditions, the Issuers at any time may terminate
some or all of their obligations under the Notes and the Indenture if the
Issuers deposit with the Trustee money or U.S. Government Obligations for the
payment of principal and interest on the Notes to redemption or maturity, as the
case may be.

         14.      Amendment, Waiver

         Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Notes may be amended with the consent of the Holders of at
least a majority in principal amount outstanding of the Notes and (ii) any past
default or compliance with any provision may be waived with the consent of the
Holders of a majority in principal amount outstanding of the Notes. Subject to
certain exceptions set forth in the Indenture, without the consent of any
Noteholder, the Issuers and the Trustee may amend the Indenture or the Notes to
cure any ambiguity, omission, defect or inconsistency, to comply with Article 5
of the Indenture, to provide for uncertificated Notes in addition to or in place
of certificated Notes, to add guarantees with respect to the Notes, to secure


                                       B-7


<PAGE>



the Notes, to add additional covenants or surrender rights and powers conferred
on the Issuers, to make any change that does not adversely affect the rights of
any Noteholder or to comply with any request of the SEC in connection with
qualifying the Indenture under the TIA.

         15.      Defaults and Remedies

         Under the Indenture, Events of Default include (i) default for 30 days
in payment of interest on the Notes; (ii) default in payment of principal on any
Note when due at its Stated Maturity, upon redemption pursuant to paragraphs 5
or 6 above, upon required repurchase, upon acceleration or otherwise, (iii)
failure by the Issuers to comply with Article 5 of the Indenture; (iv) failure
by the Issuers to comply for 30 days after the notice specified in the paragraph
below with certain covenants (other than a failure to purchase Notes upon the
occurrence of certain events) of the Indenture; (v) failure by the Issuers to
comply for 60 days after the Issuers receive the notice specified in the
paragraph below with any of their other agreements in the Indenture (other than
those referred to in (i), (ii), (iii) or (iv) above); (vi) failure by the
Issuers or any Significant Subsidiary to pay any Indebtedness within any
applicable grace period after final maturity or acceleration by the Holders
thereof because of a default and the total amount of such Indebtedness unpaid or
accelerated exceeds $10 million; (vii) certain events of bankruptcy, insolvency
or reorganization of the Issuers or any Significant Subsidiary; (viii) the
rendering of any judgments or decrees for the payment of money in excess of $10
million, or its foreign equivalent at the time, is entered against the Issuers
or any Significant Subsidiary if such judgment or decree remains outstanding for
a period of 60 days following entry of such judgment and is not discharged,
bonded, waived or stayed within 30 days after notice thereof, (ix) a Subsidiary
Guarantee ceases to be in full force and effect (other than in accordance with
the terms of such Subsidiary Guarantee or the Indenture) or a Subsidiary
Guarantor denies or disaffirm its obligations under its Subsidiary Guarantee,
and (x) the security interest under the Escrow Security Agreement between the
Issuers and U.S. Bank Trust National Association, dated April 29, 1998 (the
"Escrow Security Agreement"), shall, at any time, cease to be in full force and
effect for any reason (other than by operation of the provisions of the
Indenture and the Escrow Security Agreement), or any security interest created
thereunder shall be declared invalid or unenforceable, or the Issuers or any
Restricted Subsidiary shall assert, in any pleading in any court of competent
jurisdiction that any such security interest is invalid or unenforceable

         A Default under clause (iv) or (v) of Section 6.1 of the Indenture will
not constitute an Event of Default until the Trustee or the Holders of at least
25% in aggregate principal amount of the outstanding Notes notify the Issuers of
the Default and the Issuers do not cure such Default within the time specified
after receipt of such notice. Such notice must specify the Default, demand that
it be remedied and state that such notice is a "Notice of Default".

         If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Notes then outstanding may
declare all the Notes to be due and payable. Certain events of bankruptcy or
insolvency are Events of Default which will result in the Notes being due and
payable immediately upon the occurrence of such Events of Default.

                                       B-8


<PAGE>



         Noteholders may not enforce the Indenture or the Notes except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Notes unless it receives reasonable indemnity or security. Subject to
certain limitations, Holders of a majority in principal amount of the Notes may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from the Noteholders notice of any continuing Default (except a Default
in payment of principal or interest) if it determines that withholding notice is
not opposed to the interests of the Holders.

         16.      Guarantee

         The obligations of the Issuers pursuant to the Indenture and the Notes,
including the repurchase obligations under the Indenture, will be
unconditionally guaranteed, on a senior unsecured basis, by each Subsidiary
Guarantor. The obligations of the Issuers pursuant to the Indenture and the
Notes will be secured to the extent provided in the Indenture and the Escrow
Security Agreement.

         17.      Trustee Dealings with the Issuers

         Subject to certain limitations imposed by the TIA, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Notes and may otherwise deal with and collect obligations owed to it
by the Issuers or any of their Affiliates and may otherwise deal with the
Issuers or any of their Affiliates with the same rights it would have if it were
not Trustee.

         18.      No Recourse Against Others

         No recourse for the payment of the principal of, premium, if any, or
interest on any of the Notes or for any claim based thereon or otherwise in
respect thereof, and no recourse under or upon any obligation, covenant or
agreement of the Issuers in the Indenture, or in any of the Notes or because of
the creation of any Indebtedness represented hereby and thereby, shall be had
against any incorporator, stockholder, member, officer, director, manager,
employee or controlling person of the Issuers or any Successor Person thereof.
Each Holder, by accepting a Note, waives and releases all such liability.

         19.      Governing Law

         THE INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO
APPLICABLE PRINCIPLES OF CONFLICT OF LAWS TO THE EXTENT THAT THE APPLICATION OF
THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

CREDIT SUISSE FIRST BOSTON CORPORATION
WASSERSTEIN PERELLA SECURITIES, INC.
c/o Credit Suisse First Boston Corporation
    Eleven Madison Avenue
    New York, New York 10010-3629

Dear Sirs:

     Chiles Offshore LLC, a Delaware limited liability company ("Chiles"), 
and Chiles Offshore Finance Corp., a Delaware corporation ("Finance" and, 
together with Chiles, the "Issuers"), propose to issue and sell to Credit 
Suisse First Boston Corporation and Wasserstein Perella Securities, Inc. 
(collectively, the "Initial Purchasers"), upon the terms set forth in a 
purchase agreement of even date herewith (the "Purchase Agreement"), 
$110,000,000 aggregate principal amount of their 10% Senior Notes due 2008 
(the "Initial Securities") to be unconditionally guaranteed (the 
"Guaranties") by Chiles Columbus LLC, a Delaware limited liability company 
("Columbus") and Chiles Magellan LLC, a Delaware limited liability company 
("Magellan" and, together with Columbus, the "Guarantors" and together with 
the Issuer, the "Company"). The Initial Securities will be issued pursuant to 
an Indenture, dated as of April 29, 1998, (the "Indenture") among the Issuer, 
the Guarantors named therein and U.S. Bank Trust National Association (the 
"Trustee"). As an inducement to the Initial Purchasers, the Issuers agree 
with the Initial Purchasers, for the benefit of the holders of the Initial 
Securities (including, without limitation, the Initial Purchasers), the 
Exchange Securities (as defined below) and the Private Exchange Securities 
(as defined below) (collectively, the "Holders"), as follows:

     1. Registered Exchange Offer. The Issuers shall, at their own cost, 
prepare and, not later than 60 days after (or if the 60th day is not a 
business day, the first business day thereafter) the date of original issue 
of the Initial Securities (the "Issue Date"), file with the Securities and 
Exchange Commission (the "Commission") a registration statement (the 
"Exchange Offer Registration

<PAGE>

Statement") on an appropriate form under the Securities Act of 1933, as 
amended (the "Securities Act"), with respect to a proposed offer (the 
"Registered Exchange Offer") to the Holders of Transfer Restricted Securities 
(as defined in Section 6 hereof), who are not prohibited by any law or policy 
of the Commission from participating in the Registered Exchange Offer, to 
issue and deliver to such Holders, in exchange for the Initial Securities, a 
like aggregate principal amount of debt securities (the "Exchange 
Securities") of the Issuers issued under the Indenture and identical in all 
material respects to the Initial Securities (except for the transfer 
restrictions relating to the Initial Securities and the provisions relating 
to the matters described in Section 6 hereof) that would be registered under 
the Securities Act. The Issuers shall use their reasonable best efforts to 
cause such Exchange Offer Registration Statement to become effective under 
the Securities Act within 120 days (or if the 120th day is not a business 
day, the first business day thereafter) after the Issue Date of the Initial 
Securities and shall keep the Exchange Offer Registration Statement effective 
for not less than 30 days (or longer, if required by applicable law) after 
the date notice of the Registered Exchange Offer is mailed to the Holders 
(such period being called the "Exchange Offer Registration Period").

     If the Issuers effect the Registered Exchange Offer, the Issuers will be 
entitled to close the Registered Exchange Offer 30 days after the 
commencement thereof provided that the Issuers have accepted all the Initial 
Securities theretofore validly tendered and not withdrawn in accordance with 
the terms of the Registered Exchange Offer.

     Following the declaration of the effectiveness of the Exchange Offer 
Registration Statement, the Issuers shall promptly commence the Registered 
Exchange Offer, it being the objective of such Registered Exchange Offer to 
enable each Holder of Transfer Restricted Securities (as defined in Section 6 
hereof) electing to exchange the Initial Securities for Exchange Securities 
(assuming that such Holder is not an affiliate of the Issuers within the 
meaning of the Securities Act, acquires the Exchange Securities in the 
ordinary course of such Holder's business and has no arrangements with any 
person to participate in the distribution of the Exchange Securities and is 
not prohibited by any law or policy of the Commission from participating in 
the Registered Exchange Offer) to trade such Exchange Securities from and 
after their receipt without any limitations or restrictions under the 
Securities Act and without material restrictions under the securities laws of 
the several states of the United States.

     The Issuers and the Initial Purchasers acknowledge that, pursuant to 
current interpretations by the Commission's staff of Section 5 of the 
Securities Act, in the absence of an applicable exemption therefrom, (i) each 
Holder which is a broker-dealer electing to exchange Securities, acquired for 
its own account as a result of market making activities or other trading 
activities, for Exchange Securities (an "Exchanging Dealer"), is required to 
deliver a prospectus containing the information set forth in (a) Annex A 
hereto on the cover, (b) Annex B hereto in the "Exchange Offer Procedures" 
section and the "Purpose of the Exchange Offer" section, and (c) Annex C 
hereto in the "Plan of Distribution" section of such prospectus in connection 
with a sale of any such Exchange Securities received by such Exchanging 
Dealer pursuant to the Registered Exchange Offer and (ii) an Initial 
Purchaser that elects to sell Exchange Securities acquired in exchange for 
Initial Securities constituting any portion of an unsold allotment is 
required to deliver a prospectus containing the

                                        2

<PAGE>

information required by Items 507 or 508 of Regulation S-K under the Securities
Act, as applicable, in connection with such sale.

     The Issuers shall use their reasonable best efforts to keep the Exchange 
Offer Registration Statement effective and to amend and supplement the 
prospectus contained therein, in order to permit such prospectus to be 
lawfully delivered by all persons subject to the prospectus delivery 
requirements of the Securities Act for such period of time as such persons 
must comply with such requirements in order to resell the Exchange 
Securities; provided, however, that (i) in the case where such prospectus and 
any amendment or supplement thereto must be delivered by an Exchanging Dealer 
or an Initial Purchaser, such period shall be the lesser of 180 days and the 
date on which all Exchanging Dealers and the Initial Purchasers have sold all 
Exchange Securities held by them (unless such period is extended pursuant to 
Section 3(j) below) and (ii) the Issuers shall make such prospectus and any 
amendment or supplement thereto, available to any broker-dealer for use in 
connection with any resale of any Exchange Securities for a period of not 
less than 90 days after the consummation of the Registered Exchange Offer.

     If, upon consummation of the Registered Exchange Offer, any Initial 
Purchaser holds Initial Securities acquired by it as part of its initial 
distribution, the Issuers, simultaneously with the delivery of the Exchange 
Securities pursuant to the Registered Exchange Offer, shall issue and deliver 
to such Initial Purchaser upon the written request of such Initial Purchaser, 
in exchange (the "Private Exchange") for the Initial Securities held by such 
Initial Purchaser, a like principal amount of debt securities of the Issuers 
issued under the Indenture and identical in all material respects (including 
the existence of restrictions on transfer under the Securities Act and the 
securities laws of the several states of the United States, but excluding 
provisions relating to the matters described in Section 6 hereof) to the 
Initial Securities (the "Private Exchange Securities"). The Initial 
Securities, the Exchange Securities and the Private Exchange Securities are 
herein collectively called the "Securities".

     In connection with the Registered Exchange Offer, the Issuers shall:

           (a) mail to each Holder a copy of the prospectus forming part of 
the Exchange Offer Registration Statement, together with an appropriate 
letter of transmittal and related documents;

           (b) keep the Registered Exchange Offer open for not less than 30 
days (or longer, if required by applicable law) after the date notice thereof 
is mailed to the Holders;

           (c) utilize the services of a depositary for the Registered 
Exchange Offer with an address in the Borough of Manhattan, The City of New 
York, which may be the Trustee or an affiliate of the Trustee;

                                        3

<PAGE>

           (d) permit Holders to withdraw tendered Securities at any time 
prior to the close of business, New York time, on the last business day on 
which the Registered Exchange Offer shall remain open; and

           (e) otherwise comply with all applicable laws.

     As soon as practicable after the close of the Registered Exchange Offer 
or the Private Exchange, as the case may be, the Issuers shall:

           (x) accept for exchange all the Securities validly tendered and 
     not withdrawn pursuant to the Registered Exchange Offer and the Private  
     Exchange;

           (y) deliver to the Trustee for cancellation all the Initial      
     Securities so accepted for exchange; and

           (z) cause the Trustee to authenticate and deliver promptly to each 
     Holder of the Initial Securities, Exchange Securities or Private Exchange 
     Securities, as the case may be, equal in principal amount to the Initial 
     Securities of such Holder so accepted for exchange.

     The Indenture will provide that the Exchange Securities will not be 
subject to the transfer restrictions set forth in the Indenture and that all 
the Securities will vote and consent together on all matters as one class and 
that none of the Securities will have the right to vote or consent as a class 
separate from one another on any matter.

     Interest on each Exchange Security and Private Exchange Security issued 
pursuant to the Registered Exchange Offer and in the Private Exchange will 
accrue from the last interest payment date on which interest was paid on the 
Initial Securities surrendered in exchange therefor or, if no interest has 
been paid on the Initial Securities, from the date of original issue of the 
Initial Securities.

     Each Holder participating in the Registered Exchange Offer shall be 
required to represent to the Issuers that at the time of the consummation of 
the Registered Exchange Offer (i) any Exchange Securities received by such 
Holder will be acquired in the ordinary course of business, (ii) such Holder 
will have no arrangements or understanding with any person to participate in 
the distribution of the Securities or the Exchange Securities within the 
meaning of the Securities Act, (iii) such Holder is not an "affiliate," as 
defined in Rule 405 of the Securities Act, of either of the Issuers or if it 
is an affiliate, such Holder will comply with the registration and prospectus 
delivery requirements of the Securities Act to the extent applicable, (iv) if 
such Holder is not a broker-dealer, that it is not engaged in, and does not 
intend to engage in, the distribution of the Exchange Securities and (v) if 
such Holder is a broker-dealer, that it will receive Exchange Securities for 
its own account in exchange for Initial Securities that were acquired as a 
result of market-making activities or other trading activities and that it 
will be required to acknowledge that it will deliver a prospectus in 
connection with any resale of such Exchange Securities.

                                        4

<PAGE>

     Notwithstanding any other provisions hereof, the Issuers will ensure 
that (i) any Exchange Offer Registration Statement and any amendment thereto 
and any prospectus forming part thereof and any supplement thereto complies 
in all material respects with the Securities Act and the rules and 
regulations thereunder, (ii) any Exchange Offer Registration Statement and 
any amendment thereto does not, when it becomes effective, contain an untrue 
statement of a material fact or omit to state a material fact required to be 
stated therein or necessary to make the statements therein not misleading and 
(iii) any prospectus forming part of any Exchange Offer Registration 
Statement, and any supplement to such prospectus, does not include an untrue 
statement of a material fact or omit to state a material fact required to be 
stated therein or necessary in order to make the statements therein, in the 
light of the circumstances under which they were made, not misleading.

     2. Shelf Registration. If, (i) because of any change in law or in 
applicable interpretations thereof by the staff of the Commission, the 
Issuers are not permitted to effect a Registered Exchange Offer, as 
contemplated by Section 1 hereof, (ii) the Registered Exchange Offer is not 
consummated within 150 days of the Issue Date, (iii) any Initial Purchaser so 
requests with respect to the Initial Securities (or the Private Exchange 
Securities) not eligible to be exchanged for Exchange Securities in the 
Registered Exchange Offer and held by it following consummation of the 
Registered Exchange Offer or (iv) any Holder (other than an Exchanging 
Dealer) is not eligible to participate in the Registered Exchange Offer or, 
in the case of any Holder (other than an Exchanging Dealer) that participates 
in the Registered Exchange Offer, such Holder does not receive freely 
tradeable Exchange Securities on the date of the exchange, the Issuers shall 
take the following actions:

        (a) The Issuers shall, at their cost, as promptly as practicable (but 
in no event more than 60 days after so required or requested pursuant to this 
Section 2) file with the Commission and thereafter shall use their reasonable 
best efforts to cause to be declared effective a registration statement (the 
"Shelf Registration Statement" and, together with the Exchange Offer 
Registration Statement, a "Registration Statement") on an appropriate form 
under the Securities Act relating to the offer and sale of the Transfer 
Restricted Securities (as defined in Section 6 hereof) by the Holders thereof 
from time to time in accordance with the methods of distribution set forth in 
the Shelf Registration Statement and Rule 415 under the Securities Act 
(hereinafter, the "Shelf Registration"); provided, however, that with respect 
to Exchange Securities received by an Initial Purchaser in exchange for 
Initial Securities constituting any portion of an unsold allotment, the 
Issuers may, if permitted by current interpretations by the Commission's 
staff, file a post-effective amendment to the Exchange Offer Registration 
Statement containing the information required by Regulation S-K Items 507 
and/or 508, as applicable, in satisfaction of its obligations under this 
paragraph (a) with respect thereof, and any such Exchange Offer Registration 
Statement, as so amended, shall be referred to herein as, and governed by, 
the provisions herein applicable to, a Shelf Registration Statement; and 
provided further, however, that no Holder (other than an Initial Purchaser) 
shall be entitled to have the Securities held by it covered by such Shelf 
Registration Statement unless such Holder agrees in writing to be bound by 
all the provisions of this Agreement applicable to such Holder as provided in 
a written notice and questionnaire delivered to all Holders (including the 
Initial Purchasers) notifying such Holders that a Shelf Registration 
Statement will be filed by the Issuers, requesting such information with 
respect to the Holders as required to be disclosed by the

                                        5

<PAGE>

Shelf Registration Statement and setting forth a deadline for response 
therein (which in no event shall be less than 30 calendar days).

        (b) The Issuers shall use their reasonable best efforts to keep the 
Shelf Registration Statement continuously effective in order to permit the 
prospectus included therein to be lawfully delivered by the Holders of the 
relevant Securities, for a period of two years (or for such longer period if 
extended pursuant to Section 3(j) below) from the date of its effectiveness 
or such shorter period that will terminate when all the Securities covered by 
the Shelf Registration Statement (i) have been sold pursuant thereto or (ii) 
are no longer restricted securities (as defined in Rule 144 under the 
Securities Act, or any successor rule thereof). During any consecutive 
365-day period, the Issuers will have the ability to suspend the availability 
of the Shelf Registration Statement for up to two periods of up to 45 
consecutive days, but no more than an aggregate of 60 days during any 365- 
day period. The Issuers shall be deemed not to have used their reasonable 
best efforts to keep the Shelf Registration Statement effective during the 
requisite period if they voluntarily take any action that would result in 
Holders of Securities covered thereby not being able to offer and sell such 
Securities during that period, unless (i) such action is required by 
applicable law, or (ii) upon the occurrence of any event contemplated by 
Section 3(b)(ii) through (v) below, such action is taken by the Issuer in 
good faith and for valid business reasons (not including avoidance of the 
Issuers' obligations hereunder), so long as the Issuers promptly thereafter 
comply with the requirements of Section 3(j) hereof, if applicable, if the 
Issuers have determined in good faith that there are no material legal or 
commercial impediments in so doing.

        (c) Notwithstanding any other provisions of this Agreement to the 
contrary, the Issuers shall cause the Shelf Registration Statement and the 
related prospectus and any amendment or supplement thereto, as of the 
effective date of the Shelf Registration Statement, amendment or supplement, 
(i) to comply in all material respects with the applicable requirements of 
the Securities Act and the rules and regulations of the Commission and (ii) 
not to contain any untrue statement of a material fact or omit to state a 
material fact required to be stated therein or necessary in order to make the 
statements therein, in light of the circumstances under which they were made, 
not misleading (other than with respect to information supplied in writing by 
the selling Holders for expressly use in the Shelf Registration Statement 
pursuant to this Agreement).

     3. Registration Procedures. In connection with any Shelf Registration 
contemplated by Section 2 hereof and, to the extent applicable, any 
Registered Exchange Offer contemplated by Section 1 hereof, the following 
provisions shall apply:

        (a) The Issuers shall (i) furnish to each Initial Purchaser, prior to 
the filing thereof with the Commission, a copy of the Registration Statement 
and each amendment thereof and each supplement, if any, to the prospectus 
included therein and, in the event that an Initial Purchaser (with respect to 
any portion of an unsold allotment from the original offering) is 
participating in the Registered Exchange Offer or the Shelf Registration 
Statement, the Issuers shall use their reasonable best efforts to reflect in 
each such document, when so filed with the Commission, such comments as such 
Initial Purchaser reasonably may propose; (ii) include the information set 
forth in Annex A

                                        6

<PAGE>

hereto on the cover, in Annex B hereto in the "Exchange Offer Procedures" 
section and the "Purpose of the Exchange Offer" section and in Annex C hereto 
in the "Plan of Distribution" section of the prospectus forming a part of the 
Exchange Offer Registration Statement and include the information set forth 
in Annex D hereto in the Letter of Transmittal delivered pursuant to the 
Registered Exchange Offer; (iii) if requested by an Initial Purchaser, 
include the information required by Items 507 or 508 of Regulation S-K under 
the Securities Act, as applicable, in the prospectus forming a part of the 
Exchange Offer Registration Statement; (iv) include within the prospectus 
contained in the Exchange Offer Registration Statement a section entitled 
"Plan of Distribution," reasonably acceptable to the Initial Purchasers, 
which shall contain a summary statement of the positions taken or policies 
made by the staff of the Commission with respect to the potential 
"underwriter" status of any broker-dealer that is the beneficial owner (as 
defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended 
(the "Exchange Act")) of Exchange Securities received by such broker-dealer 
in the Registered Exchange Offer (a "Participating Broker-Dealer"), whether 
such positions or policies have been publicly disseminated by the staff of 
the Commission or such positions or policies, in the reasonable judgment of 
the Initial Purchasers based upon advice of counsel (which may be in-house 
counsel), represent the prevailing views of the staff of the Commission; and 
(v) in the case of a Shelf Registration Statement, include the names of the 
Holders, who propose to sell Securities pursuant to the Shelf Registration 
Statement, as selling securityholders.

        (b) The Issuers shall give written notice to the Initial Purchasers, 
and, in the case of a Shelf Registration Statement only, the Holders of the 
Securities and, in the case of a Exchange Offer Registration Statement only, 
any Participating Broker-Dealer from whom the Issuers have received prior 
written notice that it will be a Participating Broker-Dealer in the 
Registered Exchange Offer (which notice pursuant to clauses (ii)-(v) hereof 
shall be accompanied by an instruction to suspend the use of the prospectus 
until the requisite changes have been made):

            (i) when the Registration Statement or any amendment thereto has
     been filed with the Commission and when the Registration Statement or any
     post-effective amendment thereto has become effective;

            (ii) of any request by the Commission for amendments or supplements
     to the Registration Statement or the prospectus included therein or for
     additional information;

            (iii) of the issuance by the Commission of any stop order  
     suspending the effectiveness of the Registration Statement or the 
     initiation of any proceedings for that purpose;

            (iv) of the receipt by the Issuers or their legal counsel of any 
     notification with respect to the suspension of the qualification of the
     Securities for sale in any jurisdiction or the initiation or threatening 
     of any proceeding for such purpose; and

                                        7

<PAGE>

            (v) of the happening of any event that requires the Issuers to make
     changes in the Registration Statement or the prospectus in order that the
     Registration Statement or the prospectus do not contain an untrue 
     statement of a material fact nor omit to state a material fact required to
     be stated therein or necessary to make the statements therein (in the case 
     of the prospectus, in light of the circumstances under which they were 
     made) not misleading (which written notice shall be accompanied by an 
     instruction to suspend the use of the prospectus until the requisite 
     changes have been made and which need not provide any detail as to the 
     nature of such event).

        (c) The Issuers shall make every reasonable commercial effort to 
obtain the withdrawal, at the earliest possible time, of any order suspending 
the effectiveness of the Registration Statement.

        (d) The Issuers shall furnish to each Holder of Securities included 
within the coverage of the Shelf Registration and each Initial Purchaser, 
without charge, one copy of the Shelf Registration Statement and any 
post-effective amendment thereto, including financial statements and 
schedules, and, if the Holder or Initial Purchaser so requests in writing, 
all exhibits thereto (excluding those, if any, incorporated by reference and 
available on-line via EDGAR).

        (e) The Issuers shall deliver to each Exchanging Dealer and each 
Initial Purchaser, without charge, one copy of the Exchange Offer 
Registration Statement and any post-effective amendment thereto, including 
financial statements and schedules, and, if any Initial Purchaser or any such 
Exchanging Dealer requests, all exhibits thereto (excluding, those, if any, 
incorporated by reference and available on-line via EDGAR).

        (f) The Issuers shall, during the Shelf Registration Period, deliver 
to each Holder of Securities included within the coverage of the Shelf 
Registration, without charge, as many copies of the prospectus (including 
each preliminary prospectus) included in the Shelf Registration Statement and 
any amendment or supplement thereto as such person may reasonably request. 
The Issuers consent, subject to the provisions of this Agreement, to the use 
of the prospectus or any amendment or supplement thereto by each of the 
selling Holders of the Securities in connection with the offering and sale of 
the Securities covered by the prospectus, or any amendment or supplement 
thereto, included in the Shelf Registration Statement.

        (g) The Issuers shall deliver to each Initial Purchaser, any 
Exchanging Dealer, any Participating Broker-Dealer and such other persons 
required to deliver a prospectus following the Registered Exchange Offer, 
without charge, as many copies of the final prospectus included in the 
Exchange Offer Registration Statement and any amendment or supplement thereto 
as such persons may reasonably request. The Issuers consent, subject to the 
provisions of this Agreement, to the use of the prospectus or any amendment 
or supplement thereto by any Initial Purchaser, if necessary, any 
Participating Broker-Dealer and such other persons required to deliver a 
prospectus following the Registered Exchange Offer in connection with the 
offering and sale of the Exchange

                                        8

<PAGE>

Securities covered by the prospectus, or any amendment or supplement thereto, 
included in such Exchange Offer Registration Statement.

        (h) Prior to any public offering of the Securities, pursuant to any 
Registration Statement, the Issuers shall register or qualify or cooperate 
with the Holders of the Securities included therein and their respective 
counsel in connection with the registration or qualification of the 
Securities for offer and sale under the securities or "blue sky" laws of such 
states of the United States as any Holder of the Securities reasonably 
requests in writing and do any and all other acts or things necessary or 
advisable to enable the offer and sale in such jurisdictions of the 
Securities covered by such Registration Statement; provided, however, that 
the Issuers shall not be required to (i) qualify generally to do business in 
any jurisdiction where it is not then so qualified or (ii) take any action 
which would subject it to general service of process or to taxation in any 
jurisdiction where it is not then so subject.

        (i) The Issuers shall cooperate with the Holders of the Securities to 
facilitate the timely preparation and delivery of certificates representing 
the Securities to be sold pursuant to any Registration Statement free of any 
restrictive legends and in such denominations and registered in such names as 
the Holders may request a reasonable period of time prior to sales of the 
Securities pursuant to such Registration Statement.

        (j) Upon the occurrence of any event contemplated by paragraphs (ii) 
through (v) of Section 3(b) above during the period for which the Issuers are 
required to maintain an effective Registration Statement, the Issuers shall 
promptly prepare and file a post-effective amendment to the Registration 
Statement or a supplement to the related prospectus and any other required 
document so that, as thereafter delivered to Holders of the Securities or 
purchasers of Securities, the prospectus will not contain an untrue statement 
of a material fact or omit to state any material fact required to be stated 
therein or necessary to make the statements therein, in light of the 
circumstances under which they were made, not misleading. If the Issuers 
notify the Initial Purchasers, the Holders of the Securities and any known 
Participating Broker-Dealer in accordance with paragraphs (ii) through (v) of 
Section 3(b) above to suspend the use of the prospectus until the requisite 
changes to the prospectus have been made, then the Initial Purchasers, the 
Holders of the Securities and any such Participating Broker-Dealers shall 
suspend use of such prospectus, and the period of effectiveness of the 
Exchange Offer Registration Statement provided for in Section 1 above shall 
be extended by the number of days from and including the date of the giving 
of such notice to and including the date when the Initial Purchasers, the 
Holders of the Securities and any known Participating Broker-Dealer shall 
have received such amended or supplemented prospectus pursuant to this 
Section 3(j).

        (k) Not later than the effective date of the applicable Registration 
Statement, the Issuers will provide a CUSIP number for the Initial 
Securities, the Exchange Securities or the Private Exchange Securities, as 
the case may be, and provide the applicable trustee with printed certificates 
for the Initial Securities, the Exchange Securities or the Private Exchange 
Securities, as the case may be, in a form eligible for deposit with The 
Depository Trust Company.

                                        9

<PAGE>

        (l) The Issuers will comply with all rules and regulations of the 
Commission to the extent and so long as they are applicable to the Registered 
Exchange Offer or the Shelf Registration and will make generally available to 
its security holders (or otherwise provide in accordance with Section 11(a) 
of the Securities Act) an earnings statement satisfying the provisions of 
Section 11(a) of the Securities Act, no later than 45 days after the end of a 
12-month period (or 90 days, if such period is a fiscal year) beginning with 
the first month of the Issuers' first fiscal quarter commencing after the 
effective date of the Registration Statement, which statement shall cover 
such 12-month period.

        (m) The Issuers shall cause the Indenture to be qualified under the 
Trust Indenture Act of 1939, as amended, in a timely manner and containing 
such changes, if any, as shall be necessary for such qualification. In the 
event that such qualification would require the appointment of a new trustee 
under the Indenture, the Issuers shall appoint a new trustee thereunder 
pursuant to the applicable provisions of the Indenture.

        (n) The Issuers may require each Holder of Securities to be sold 
pursuant to the Shelf Registration Statement to furnish to the Issuers such 
information regarding the Holder and the distribution of the Securities as 
the Issuers may from time to time reasonably require for inclusion in the 
Shelf Registration Statement, and the Issuers may exclude from such 
registration the Securities of any Holder that unreasonably fails to furnish 
such information within a reasonable time after receiving such request.

        (o) The Issuers shall enter into such customary agreements 
(including, if requested, an underwriting agreement in customary form with 
managing underwriters reasonably acceptable to the Issuers) and shall use 
reasonable best efforts to take all such other action, if any, as any Holder 
of the Securities shall reasonably request in order to facilitate the 
disposition of the Securities pursuant to any Shelf Registration.

        (p) In the case of any Shelf Registration, the Issuers and the 
Guarantors shall (i) make reasonably available for inspection by the Holders 
of the Securities, any underwriter participating in any disposition pursuant 
to the Shelf Registration Statement and any attorney, accountant or other 
agent retained by the Holders of the Securities or any such underwriter all 
relevant financial and other records, pertinent corporate documents and 
properties of the Issuers and (ii) cause the Issuers' officers, directors, 
employees, accountants and auditors to supply all relevant information 
reasonably requested by the Holders of the Securities or any such 
underwriter, attorney, accountant or agent in connection with the Shelf 
Registration Statement, in each case, as shall be reasonably necessary to 
enable such persons, to conduct a reasonable investigation within the meaning 
of Section 11 of the Securities Act; provided, however, that any information 
that is designated in writing by the Issuers, in good faith, as confidential 
at the time of delivery of such information shall be kept confidential by the 
Holders or any such underwriter, attorney, accountant or agent, unless such 
disclosure is made in connection with a court proceeding or required by law, 
or such information becomes available to the public generally or through a 
third party without an accompanying obligation of confidentiality and that 
the foregoing inspection and information

                                       10

<PAGE>

gathering (i) shall be coordinated on behalf of the Initial Purchasers by you 
and on behalf of the other parties, by one counsel (the "Designated Counsel") 
designated by the Holders of a majority in principal amount of the Securities 
covered by the Registration Statement and (ii) shall not be available for any 
such Holder that is a competitor of the Issuers.

        (q) In the case of any Shelf Registration, the Issuers and the 
Guarantors, if requested by the Designated Counsel, shall cause (i) their 
counsel to deliver an opinion and updates thereof relating to the Securities 
in customary form addressed to such Holders and the managing underwriters, if 
any, thereof and dated, in the case of the initial opinion, the effective 
date of such Shelf Registration Statement (it being agreed that the matters 
to be covered by such opinion shall include, without limitation, subject to 
usual and customary qualifications, the due incorporation and good standing 
of the Issuers and its subsidiaries; the qualification of the Issuers and its 
subsidiaries to transact business as foreign corporations; the due 
authorization, execution and delivery of the relevant agreement of the type 
referred to in Section 3(o) hereof; the due authorization, execution, 
authentication and issuance, and the validity and enforceability, of the 
applicable Securities; the absence of material legal or governmental 
proceedings involving the Issuers and its subsidiaries; the absence of 
governmental approvals required to be obtained in connection with the Shelf 
Registration Statement, the offering and sale of the applicable Securities, 
or any agreement of the type referred to in Section 3(o) hereof; the 
compliance as to form of such Shelf Registration Statement and any documents 
incorporated by reference therein and of the Indenture with the requirements 
of the Securities Act and the Trust Indenture Act, respectively; and, as of 
the date of the opinion and as of the effective date of the Shelf 
Registration Statement or most recent post-effective amendment thereto, as 
the case may be, negative assurance with respect to the absence from such 
Shelf Registration Statement and the prospectus included therein, as then 
amended or supplemented, and from any documents incorporated by reference 
therein of an untrue statement of a material fact or the omission to state 
therein a material fact required to be stated therein or necessary to make 
the statements therein not misleading (in the case of any such documents, in 
the light of the circumstances existing at the time that such documents were 
filed with the Commission under the Exchange Act)); (ii) its officers to 
execute and deliver all customary documents and certificates and updates 
thereof requested by the Designated Counsel; and (iii) its independent public 
accountants to provide to the selling Holders of the applicable Securities 
and any managing underwriter therefor a comfort letter in customary form and 
covering matters of the type customarily covered in comfort letters in 
connection with primary underwritten offerings, subject to receipt of 
appropriate documentation as contemplated, and only if permitted, by 
Statement of Auditing Standards No. 72.

        (r) In the case of the Registered Exchange Offer, if requested by any 
Initial Purchaser or any known Participating Broker-Dealer, the Issuers shall 
cause (i) their counsel to deliver to such Initial Purchaser or such 
Participating Broker-Dealer a signed opinion substantially in the form set 
forth in Section 6(c) of the Purchase Agreement with such changes as are 
customary in connection with the preparation of a Registration Statement and 
(ii) their independent public accountants to deliver to such Initial 
Purchaser or such Participating Broker- Dealer a comfort letter, in customary 
form, meeting the requirements as to the substance thereof as set forth in 
Section 6(a) of the Purchase Agreement, with appropriate date changes.

                                       11

<PAGE>

        (s) If a Registered Exchange Offer or a Private Exchange is to be 
consummated, upon delivery of the Initial Securities by Holders to the 
Issuers (or to such other Person as directed by the Issuers) in exchange for 
the Exchange Securities or the Private Exchange Securities, as the case may 
be, the Issuers shall mark, or caused to be marked, on the Initial Securities 
so exchanged that such Initial Securities are being canceled in exchange for 
the Exchange Securities or the Private Exchange Securities, as the case may 
be; in no event shall the Initial Securities be marked as paid or otherwise 
satisfied.

        (t) The Company will use its reasonable best efforts to continue to 
have the Securities rated by the rating agencies that rated the Securities in 
connection with the sale to the Initial Purchasers and, at the request of any 
Holder, confirm to such Holder the current rating of the Securities at the 
time of such request.

        (u) In the event that any broker-dealer registered under the Exchange 
Act shall underwrite any Securities or participate as a member of an 
underwriting syndicate or selling group or "assist in the distribution" 
(within the meaning of the Conduct Rules (the "Rules") of the National 
Association of Securities Dealers, Inc. ("NASD")) thereof, whether as a 
Holder of such Securities or as an underwriter, a placement or sales agent or 
a broker or dealer in respect thereof, or otherwise, the Issuers will assist 
such broker-dealer in complying with the requirements of such Rules, 
including, without limitation, by (i) if such Rules, including Rule 2720, 
shall so require, engaging a "qualified independent underwriter" (as defined 
in Rule 2720) on customary terms to participate in the preparation of the 
Registration Statement relating to such Securities, to exercise usual 
standards of due diligence in respect thereto and, if any portion of the 
offering contemplated by such Registration Statement is an underwritten 
offering or is made through a placement or sales agent, to recommend the 
yield of such Securities, (ii) indemnifying any such qualified independent 
underwriter to the extent of the indemnification of underwriters provided in 
Section 5 hereof and (iii) providing such information to such broker-dealer 
as may be required in order for such broker-dealer to comply with the 
requirements of the Rules.

        (v) The Issuers shall use their reasonable best efforts to take all 
other steps necessary to effect the registration of the Securities covered by 
a Registration Statement contemplated hereby.

     4. Registration Expenses. The Issuers shall bear all fees and expenses 
incurred in connection with the performance of their obligations under 
Sections 1 through 3 hereof (including the reasonable fees and expenses, if 
any, of Andrews & Kurth L.L.P., counsel for the Initial Purchasers, incurred 
in connection with the Registered Exchange Offer), whether or not the 
Registered Exchange Offer or a Shelf Registration is filed or becomes 
effective, and, in the event of a Shelf Registration, shall bear or reimburse 
the Holders of the Securities covered thereby for the reasonable fees and 
disbursements of Designated Counsel.

     5. Indemnification. (a) The Issuers and the Guarantors, jointly and 
severally, agree to indemnify and hold harmless each Holder of the 
Securities, any Participating Broker-Dealer and each

                                       12

<PAGE>

person, if any, who controls such Holder or such Participating Broker-Dealer 
within the meaning of the Securities Act or the Exchange Act (each Holder, 
any Participating Broker-Dealer and such controlling persons are referred to 
collectively as the "Indemnified Parties") from and against any losses, 
claims, damages or liabilities, joint or several, or any actions in respect 
thereof (including, but not limited to, any losses, claims, damages, 
liabilities or actions relating to purchases and sales of the Securities) to 
which each Indemnified Party may become subject under the Securities Act, the 
Exchange Act or otherwise, insofar as such losses, claims, damages, 
liabilities or actions arise out of or are based upon any untrue statement or 
alleged untrue statement of a material fact contained in a Registration 
Statement or prospectus or in any amendment or supplement thereto or in any 
preliminary prospectus relating to a Shelf Registration, or arise out of, or 
are based upon, the omission or alleged omission to state therein a material 
fact required to be stated therein or necessary to make the statements 
therein not misleading, and shall reimburse, as incurred, the Indemnified 
Parties for any legal or other expenses reasonably incurred by them in 
connection with investigating or defending any such loss, claim, damage, 
liability or action in respect thereof; provided, however, that (i) the 
Issuers shall not be liable in any such case to the extent that such loss, 
claim, damage or liability arises out of or is based upon any untrue 
statement or alleged untrue statement or omission or alleged omission made in 
a Registration Statement or prospectus or in any amendment or supplement 
thereto or in any preliminary prospectus relating to a Shelf Registration in 
reliance upon and in conformity with written information pertaining to such 
Holder and furnished to the Issuers by or on behalf of such Holder 
specifically for inclusion therein and (ii) with respect to any untrue 
statement or omission or alleged untrue statement or omission made in any 
preliminary prospectus relating to a Shelf Registration Statement, the 
indemnity agreement contained in this subsection (a) shall not inure to the 
benefit of any Holder or Participating Broker-Dealer from whom the person 
asserting any such losses, claims, damages or liabilities purchased the 
Securities concerned, to the extent that a prospectus relating to such 
Securities was required to be delivered by such Holder or Participating 
Broker-Dealer under the Securities Act in connection with such purchase and 
any such loss, claim, damage or liability of such Holder or Participating 
Broker-Dealer results from the fact that there was not sent or given to such 
person, at or prior to the written confirmation of the sale of such 
Securities to such person, a copy of the final prospectus if the Issuers had 
previously furnished copies thereof to such Holder or Participating 
Broker-Dealer; provided further, however, that this indemnity agreement will 
be in addition to any liability which the Issuers may otherwise have to such 
Indemnified Party. The Issuers shall also indemnify underwriters, their 
officers and directors and each person who controls such underwriters within 
the meaning of the Securities Act or the Exchange Act to the same extent as 
provided above with respect to the indemnification of the Holders of the 
Securities if requested by such Holders.

        (b) Each Holder of the Securities, severally and not jointly, will 
indemnify and hold harmless the Issuers and each person, if any, who controls 
the Issuers within the meaning of the Securities Act or the Exchange Act from 
and against any losses, claims, damages or liabilities or any actions in 
respect thereof, to which the Issuers or any such controlling person may 
become subject under the Securities Act, the Exchange Act or otherwise, 
insofar as such losses, claims, damages, liabilities or actions arise out of 
or are based upon any untrue statement or alleged untrue statement of a 
material fact contained in a Registration Statement or prospectus or in any 
amendment

                                       13

<PAGE>

or supplement thereto or in any preliminary prospectus relating to a Shelf 
Registration, or arise out of or are based upon the omission or alleged 
omission to state therein a material fact necessary to make the statements 
therein not misleading, but in each case only to the extent that the untrue 
statement or omission or alleged untrue statement or omission was made in 
reliance upon and in conformity with written information pertaining to such 
Holder and furnished to the Issuers by or on behalf of such Holder 
specifically for inclusion therein; and, subject to the limitation set forth 
immediately preceding this clause, shall reimburse, as incurred, the Issuers 
for any legal or other expenses reasonably incurred by the Issuers or any 
such controlling person in connection with investigating or defending any 
loss, claim, damage, liability or action in respect thereof. This indemnity 
agreement will be in addition to any liability which such Holder may 
otherwise have to the Issuers or any of its controlling persons.

        (c) Promptly after receipt by an indemnified party under this Section 
5 of notice of the commencement of any action or proceeding (including a 
governmental investigation), such indemnified party will, if a claim in 
respect thereof is to be made against the indemnifying party under this 
Section 5, notify the indemnifying party of the commencement thereof; but the 
omission so to notify the indemnifying party will not, in any event (except 
to the extent that a defense or counterclaim thereto has been foreclosed 
thereby), relieve the indemnifying party from any obligations to any 
indemnified party other than the indemnification obligation provided in 
paragraph (a) or (b) above. In case any such action is brought against any 
indemnified party, and it notifies the indemnifying party of the commencement 
thereof, the indemnifying party will be entitled to participate therein and, 
to the extent that it may wish, jointly with any other indemnifying party 
similarly notified, to assume the defense thereof, with counsel reasonably 
satisfactory to such indemnified party (who shall not, except with the 
consent of the indemnified party, be counsel to the indemnifying party), and 
after notice from the indemnifying party to such indemnified party of its 
election so to assume the defense thereof the indemnifying party will not be 
liable to such indemnified party under this Section 5 for any legal or other 
expenses, other than reasonable costs of investigation, subsequently incurred 
by such indemnified party in connection with the defense thereof. No 
indemnifying party shall, without the prior written consent of the 
indemnified party, effect any settlement of any pending or threatened action 
in respect of which any indemnified party is or could have been a party and 
indemnity could have been sought hereunder by such indemnified party unless 
such settlement includes an unconditional release of such indemnified party 
from all liability on any claims that are the subject matter of such action.

        (d) If the indemnification provided for in this Section 5 is 
unavailable or insufficient to hold harmless an indemnified party under 
subsections (a) or (b) above, then each indemnifying party shall contribute 
to the amount paid or payable by such indemnified party as a result of the 
losses, claims, damages or liabilities (or actions in respect thereof) 
referred to in subsection (a) or (b) above (i) in such proportion as is 
appropriate to reflect the relative benefits received by the indemnifying 
party or parties on the one hand and the indemnified party on the other from 
the exchange of the Securities, pursuant to the Registered Exchange Offer, or 
(ii) if the allocation provided by the foregoing clause (i) is not permitted 
by applicable law, in such proportion as is appropriate to reflect not only 
the relative benefits referred to in clause (i) above but also the

                                       14

<PAGE>

relative fault of the indemnifying party or parties on the one hand and the 
indemnified party on the other in connection with the statements or omissions 
that resulted in such losses, claims, damages or liabilities (or actions in 
respect thereof) as well as any other relevant equitable considerations. The 
relative fault of the parties shall be determined by reference to, among 
other things, whether the untrue or alleged untrue statement of a material 
fact or the omission or alleged omission to state a material fact relates to 
information supplied by the Issuers on the one hand or such Holder or such 
other indemnified party, as the case may be, on the other, and the parties' 
relative intent, knowledge, access to information and opportunity to correct 
or prevent such statement or omission. The amount paid by an indemnified 
party as a result of the losses, claims, damages or liabilities referred to 
in the first sentence of this subsection (d) shall be deemed to include any 
legal or other expenses reasonably incurred by such indemnified party in 
connection with investigating or defending any action or claim which is the 
subject of this subsection (d). Notwithstanding any other provision of this 
Section 5(d), the Holders of the Securities shall not be required to 
contribute any amount in excess of the amount by which the net proceeds 
received by such Holders from the sale of the Securities pursuant to a 
Registration Statement exceeds the amount of damages which such Holders have 
otherwise been required to pay by reason of such untrue or alleged untrue 
statement or omission or alleged omission. No person guilty of fraudulent 
misrepresentation (within the meaning of Section 11(f) of the Securities Act) 
shall be entitled to contribution from any person who was not guilty of such 
fraudulent misrepresentation. For purposes of this paragraph (d), each 
person, if any, who controls such indemnified party within the meaning of the 
Securities Act or the Exchange Act shall have the same rights to contribution 
as such indemnified party and each person, if any, who controls the Issuers 
within the meaning of the Securities Act or the Exchange Act shall have the 
same rights to contribution as the Issuers.

        (e) The agreements contained in this Section 5 shall survive the sale 
of the Securities pursuant to a Registration Statement and shall remain in 
full force and effect, regardless of any termination or cancellation of this 
Agreement or any investigation made by or on behalf of any indemnified party.

     6. Additional Interest Under Certain Circumstances. (a) Additional 
interest (the "Additional Interest") with respect to the Initial Securities 
shall be assessed as follows if any of the following events occur (each such 
event in clauses (i) through (iii) below a "Registration Default"):

            (i) If by June 28, 1998, neither the Exchange Offer Registration
     Statement nor a Shelf Registration Statement has been filed with the
     Commission;

            (ii) If by August 27, 1998, neither the Registered Exchange Offer 
     is consummated nor, if required in lieu thereof, the Shelf Registration
     Statement is declared effective by the Commission; or

            (iii) If after either the Exchange Offer Registration Statement or
     the Shelf Registration Statement is declared effective (A) such
     Registration Statement thereafter ceases to be effective; or (B) such
     Registration Statement or the related prospectus ceases to be


                                       15

<PAGE>

     usable (except as permitted in paragraph (b)) in connection with resales of
     Transfer Restricted Securities during the periods specified herein because
     either (1) any event occurs as a result of which the related prospectus
     forming part of such Registration Statement would include any untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein in the light of the circumstances under
     which they were made not misleading, or (2) it shall be necessary to amend
     such Registration Statement or supplement the related prospectus, to comply
     with the Securities Act or the Exchange Act or the respective rules
     thereunder.

Additional Interest shall accrue on the Initial Securities over and above the 
interest set forth in the title of the Securities from and including the date 
on which any such Registration Default shall occur to but excluding the date 
on which all such Registration Defaults have been cured, at a rate of 0.50% 
per annum.

        (b) A Registration Default referred to in Section 6(a)(iii)(B) hereof 
shall be deemed not to have occurred and be continuing in relation to a Shelf 
Registration Statement or the related prospectus if (i) such Registration 
Default has occurred solely as a result of (x) the filing of a post-effective 
amendment to such Shelf Registration Statement to incorporate annual audited 
financial information with respect to the Issuers where such post-effective 
amendment is not yet effective and needs to be declared effective to permit 
Holders to use the related prospectus or (y) other material events, with 
respect to the Issuers that would need to be described in such Shelf 
Registration Statement or the related prospectus and (ii) in the case of 
clause (y), the Issuers are proceeding promptly and in good faith to amend or 
supplement such Shelf Registration Statement and related prospectus to 
describe such events; provided, however, that in any case if such 
Registration Default occurs for a continuous period in excess of 30 days, 
Additional Interest shall be payable in accordance with the above paragraph 
from the day such Registration Default occurs until such Registration Default 
is cured.

        (c) Any amounts of Additional Interest due pursuant to clause (i), 
(ii) or (iii) of Section 6(a) above will be payable in cash on the regular 
interest payment dates with respect to the Initial Securities. The amount of 
Additional Interest will be determined by multiplying the applicable 
Additional Interest rate by the principal amount of the Initial Securities, 
multiplied by a fraction, the numerator of which is the number of days such 
Additional Interest rate was applicable during such period (determined on the 
basis of a 360-day year comprised of twelve 30-day months), and the 
denominator of which is 360.

        (d) "Transfer Restricted Securities" means each Security until (i) 
the date on which such Transfer Restricted Security has been exchanged by a 
person other than a broker-dealer for a freely transferable Exchange Security 
in the Registered Exchange Offer, (ii) following the exchange by a 
broker-dealer in the Registered Exchange Offer of an Initial Security for an 
Exchange Security, the date on which such Exchange Security is sold to a 
purchaser who receives from such broker-dealer on or prior to the date of 
such sale a copy of the prospectus contained in the Exchange Offer 
Registration Statement, (iii) the date on which such Initial Security has 
been effectively

                                       16

<PAGE>

registered under the Securities Act and disposed of in accordance with the 
Shelf Registration Statement or (iv) the date on which such Initial Security 
is distributed to the public pursuant to Rule 144 under the Securities Act or 
is saleable pursuant to Rule 144(k) under the Securities Act.

        (e) Notwithstanding anything to the contrary contained in this 
Agreement, it is hereby acknowledged and agreed that the Issuers will have no 
other liabilities for monetary damages to the Initial Purchasers or any 
Holder for a Registration Default other than the payment of Additional 
Interest; provided, however, that in the event of a Registration Default, the 
Initial Purchasers and any Holder shall be entitled to, and the Issuers shall 
not oppose the granting of, equitable relief, including injunction and 
specific performance, to enforce the Issuers' obligations under Sections 1 
and 2 hereof.

     7. Rules 144 and 144A. The Issuers shall use their reasonable best 
efforts to file the reports required to be filed by it under the Securities 
Act and the Exchange Act in a timely manner and, if at any time the Issuers 
are not required to file such reports, they will, upon the request of any 
Holder of Initial Securities, make publicly available other information so 
long as necessary to permit sales of their securities pursuant to Rules 144 
and 144A. The Issuers covenant that they will take such further action as any 
Holder of Initial Securities may reasonably request, all to the extent 
required from time to time to enable such Holder to sell Initial Securities 
without registration under the Securities Act within the limitation of the 
exemptions provided by Rules 144 and 144A (including the requirements of Rule 
144A(d)(4)). The Issuers will provide a copy of this Agreement to prospective 
purchasers of Initial Securities identified to the Issuers by the Initial 
Purchasers upon request. Upon the request of any Holder of Initial 
Securities, the Issuers shall deliver to such Holder a written statement as 
to whether it has complied with such requirements. Notwithstanding the 
foregoing, nothing in this Section 7 shall be deemed to require the Issuers 
to register any of its securities pursuant to the Exchange Act.

     8. Underwritten Registrations. If any of the Transfer Restricted 
Securities covered by any Shelf Registration are to be sold in an 
underwritten offering, the investment banker or investment bankers and 
manager or managers that will administer the offering ("Managing 
Underwriters") will be selected by the Holders of a majority in aggregate 
principal amount of such Transfer Restricted Securities to be included in 
such offering, subject to the consent of the Issuers, which shall not be 
unreasonably withheld.

     No person may participate in any underwritten registration hereunder 
unless such person (i) agrees to sell such person's Transfer Restricted 
Securities on the basis reasonably provided in any underwriting arrangements 
approved by the persons entitled hereunder to approve such arrangements and 
(ii) completes and executes all questionnaires, powers of attorney, 
indemnities, underwriting agreements and other documents reasonably required 
under the terms of such underwriting arrangements.

     9. Miscellaneous.

     Each broker-dealer that receives Exchange Securities for its own account 
pursuant to the Exchange Offer must acknowledge that it will deliver a 
prospectus in connection with any resale of such Exchange Securities. The 
Letter of Transmittal states that by so acknowledging and by delivering a 
prospectus, a broker-dealer will not be deemed to admit that it is an

    Each broker-dealer that receives Exchange Securities for its own account

                                                                        ANNEX C

                              PLAN OF DISTRIBUTION

    Each broker-dealer that receives Exchange Securities for its own account 
pursuant to the Exchange Offer must acknowledge that it will deliver a 
prospectus in connection with any resale of such Exchange Securities. This 
Prospectus, as it may be amended or supplemented from time to time, may be 
used by a broker-dealer in connection with resales of Exchange Securities 
received in exchange for Initial Securities where such Initial Securities 
were acquired as a result of market-making activities or other trading 
activities. The Issuers have agreed that, for a period of 180 days after the 
Expiration Date, they will make this prospectus, as amended or supplemented, 
available to any broker-dealer for use in connection with any such resale. In 
addition, until , 199 , all dealers effecting transactions in the Exchange 
Securities may be required to deliver a prospectus.1

    The Issuers will not receive any proceeds from any sale of Exchange 
Securities by broker-dealers. Exchange Securities received by broker-dealers 
for their own account pursuant to the Exchange Offer may be sold from time to 
time in one or more transactions in the over-the-counter market, in 
negotiated transactions, through the writing of options on the Exchange 
Securities or a combination of such methods of resale, at market prices 
prevailing at the time of resale, at prices related to such prevailing market 
prices or negotiated prices. Any such resale may be made directly to 
purchasers or to or through brokers or dealers who may receive compensation 
in the form of commissions or concessions from any such broker-dealer or the 
purchasers of any such Exchange Securities. Any broker-dealer that resells 
Exchange Securities that were received by it for its own account pursuant to 
the Exchange Offer and any broker or dealer that participates in a 
distribution of such Exchange Securities may be deemed to be an "underwriter" 
within the meaning of the Securities Act and any profit on any such resale of 
Exchange Securities and any commissions or concessions received by any such 
persons may be deemed to be underwriting compensation under the Securities 
Act. The Letter of Transmittal states that, by acknowledging that it will 
deliver and by delivering a prospectus, a broker-dealer will not be deemed to 
admit that it is an "underwriter" within the meaning of the Securities Act.

    For a period of 180 days after the Expiration Date the Issuers will promptly
send additional copies of this Prospectus and any amendment or supplement to
this Prospectus to any broker-dealer that requests such documents in the Letter
of Transmittal. The Issuers have agreed to pay all expenses incident to the
Exchange Offer (including the expenses of one counsel for the Holders of the
Securities) other than commissions or concessions of any brokers or dealers and
will indemnify the Holders of the Securities (including any broker-dealers)
against certain liabilities, including liabilities under the Securities Act.

Offering Document; and each of the Subsidiary Guarantors is duly qualified to 
do business as a foreign limited liability company in good standing in all

general equity principles.

          (f) Except as disclosed in the Offering Document, there are no

the Offered Securities.

under, any statute, any rule, regulation or order of any governmental agency 
or body or any court, domestic or foreign, having jurisdiction over the

Guarantors is a party or by which the Issuers or the Subsidiary Guarantors 
are bound or to which any of the properties of the Issuers or the Subsidiary 
Guarantors are subject, or the Amended and Restated Operating Agreement, as 
amended, of the Company, the Certificate of Incorporation and Bylaws of 
Finance or the Operating Agreement of each of the Subsidiary Guarantors; and 
the Issuers have full power and authority to authorize, issue and sell the 
Offered Securities as contemplated by this Agreement.

          (i) Each of this Agreement and Registration Rights Agreement has

Escrow Security Agreement creates in favor of the Collateral Agent (as 
defined therein) acting as agent for the Trustee as the secured party, a 
valid perfected first priority security interest in all right, title and 
interest in the Collateral (as defined therein).

          (k) Except as disclosed in the Offering Document, the Issuers and 
the Subsidiary Guarantors have good and marketable title to all real 
properties and all other properties and assets owned by them, in each case 
free from liens, encumbrances and defects that would materially affect the

by them; and except as disclosed in the Offering Document, the Issuers and 
the Subsidiary Guarantors hold any leased real or personal property under 
valid and enforceable leases with no exceptions that would materially

certificates, authorities or permits issued by appropriate governmental 
agencies or bodies necessary to conduct the business now operated by them and 
have not received any notice of proceedings relating to the revocation or 
modification of any such certificate, authority or permit that, if determined 
adversely to the Issuers or the Subsidiary Guarantors, would individually or 
in the aggregate have a material adverse effect on the Issuers and the 
Subsidiary Guarantors taken as a whole.

          (m) No labor dispute with the employees of the Issuers or the 
Subsidiary Guarantors exists or, to the knowledge of the Issuers and 
Subsidiary Guarantors, is imminent that might have a material adverse effect

                                        4

<PAGE>

          (n) None of the Issuers or the Subsidiary Guarantors is in 
violation of any statute, any rule, regulation, decision or order of any 
governmental agency or body or any court, domestic or foreign, relating to 
the use, disposal or release of hazardous or toxic substances or relating to 
the protection or restoration of the environment or human exposure to 
hazardous or toxic substances (collectively, "environmental laws"), owns or 
operates any real property contaminated with any substance that is subject to 
any environmental laws, is liable for any off-site disposal or contamination 
pursuant to any environmental laws, or is subject to any claim relating to 
any environmental laws, which violation, contamination, liability or claim 
would individually or in the aggregate have a material adverse effect on the 
Issuers and the Subsidiary Guarantors taken as a whole; and none of the 
Issuers or the Subsidiary Guarantors is aware of any pending investigation 
which might lead to such a claim.

          (o) There are no pending actions, suits or proceedings against or 
affecting the Issuers, the Subsidiary Guarantors or any of their respective 
properties that, if determined adversely to the Issuers and the Subsidiary 
Guarantors, would individually or in the aggregate have a material adverse 
effect on the condition (financial or other), business, properties or results 
of operations of the Issuers and the Subsidiary Guarantors taken as a whole, 
or would materially and adversely affect the ability of the Issuers and the 
Subsidiary Guarantors to perform their obligations under the Indenture, the 
Registration Rights Agreement or the Escrow Agreement, or which are otherwise 
material in the context of the sale of the Offered Securities; and no such 
actions, suits or proceedings are threatened or, to the Issuers' or the 
Subsidiary Guarantors' knowledge, contemplated.

          (p) The assumptions used in preparing, and the estimates disclosed 
in, the forecasted financial information under the caption "Certain Financial 
Forecast Information" represent the Issuers' current best assumptions and 
estimates of the anticipated results of operations for the Company and its 
consolidated subsidiaries for each of the years in the three-year period 
ended December 31, 2001, and the assumptions disclosed therein have been 
prepared in good faith by the Issuers and on reasonable basis, and are all 
those the Issuers and the Guarantors believe are significant to the 
forecasted financial information.

          (q) The financial statements included in the Offering Document 
present fairly the financial position of the Company and its consolidated 
subsidiaries as of the dates shown and their results of operations and cash 
flows for the periods shown, and such financial statements have been prepared 
in conformity with the generally accepted accounting principles in the United 
States applied on a consistent basis. The financial data included in the 
Offering Document relating to payments under the Construction Contracts (as 
defined in the Offering Document) and for owner furnished equipment and 
overhead, with respect to 1997, fairly present actual payments made, and, 
with respect to periods thereafter, represent the Company's best assumptions 
and estimates of the amounts and timing of such payments, and have been 
prepaid by the Issuers in good faith and on a reasonable basis. The 
statements in the Offering Document in the second paragraph under the caption 
"Management's Discussion and Analysis of Financial Condition and Results of 
Operations --Overview" with respect to Finance and the Subsidiary Guarantors 
are true and correct.

                                        5

<PAGE>

          (r) Since the date of the latest audited financial statements 
included in the Offering Document there has been no material adverse change, 
nor any development or event involving a prospective material adverse change, 
in the condition (financial or other), business, properties (including, 
without limitation, the construction in progress of the Rigs (as defined in 
the Offering Document) and any owner furnished equipment relating thereto) or 
results of operations of the Issuers and the Subsidiary Guarantors taken as a 
whole, and there has been no dividend or distribution of any kind declared, 
paid or made by the Issuers or the Subsidiary Guarantors.

          (s) Each of the Construction Contracts and binder for the 
"delay-in-delivery" insurance policy relating to the Rigs described in the 
Offering Documents is in full force and effect and no default or event that 
with notice, a lapse of time, or both, would constitute a default, exists 
thereunder.

          (t) None of the Issuers or the Subsidiary Guarantors is an open-end 
investment company, unit investment trust or face-amount certificate company 
that is or is required to be registered under Section 8 of the United States 
Investment Company Act of 1940 (the "Investment Company Act"); and none of 
the Issuers or the Subsidiary Guarantors is or, after giving effect to the 
offering and sale of the Offered Securities and the application of the 
proceeds thereof as described in the Offering Document, will be, an 
"investment company" as defined in the Investment Company Act.

          (u) No securities of the same class (within the meaning of Rule 
144A(d)(3) under the Securities Act) as the Offered Securities are listed on 
any national securities exchange registered under Section 6 of the Securities 
Exchange Act of 1934 (the "Exchange Act") or quoted in a U.S. automated 
inter-dealer quotation system.

          (v) Assuming the accuracy of the representations and warranties of 
the Purchasers and the compliance by the Purchasers with the covenants set 
forth in Section 4 hereof, the offer and sale of the Offered Securities in 
the manner contemplated by this Agreement will be exempt from the 
registration requirements of the Securities Act by reason of Section 4(2) 
thereof, Rule 144A thereunder ("Rule 144A") and Regulation S under the 
Securities Act ("Regulation S"); and prior to the effectiveness of a 
registration statement as contemplated in the Registration Rights Agreement, 
it is not necessary to qualify an indenture in respect of the Offered 
Securities under the United States Trust Indenture Act of 1939, as amended 
(the "Trust Indenture Act").

          (w) None of the Issuers, Subsidiary Guarantors or any of their 
affiliates, or any person acting on its or their behalf (i) has, within the 
six-month period prior to the date hereof, offered or sold in the United 
States or to any U.S. person (as such terms are defined in Regulation S under 
the Securities Act) the Offered Securities or any security of the same class 
or series as the Offered Securities or (ii) has offered or will offer or sell 
the Offered Securities (A) in the United States by means of any form of 
general solicitation or general advertising within the meaning of Rule 502(c) 
under the Securities Act or (B) with respect to any such securities sold in 
reliance on Rule 903 of Regulation S, by means of any directed selling 
efforts within the meaning of Rule 902(b) of

                                        6

<PAGE>

Regulation S. Assuming the accuracy of the representations and warranties of 
the Purchasers and compliance by the Purchaser with the covenants set forth 
in Section 4 hereof, the Issuers, the Subsidiary Guarantors, their affiliates 
and any person acting on their behalf have complied and will comply with the 
offering restrictions requirement of Regulation S. The Issuers and the 
Subsidiary Guarantors have not entered and will not enter into any 
contractual arrangement with respect to the distribution of the Offered 
Securities except for this Agreement and the Registration Rights Agreement.

          (x) The proceeds to the Issuers from the offering of the Offered 
Securities will not be used to purchase or carry any "margin security" or 
"margin stock", within the meaning of Regulations G, T, U or X, as 
applicable, of the Board of Governors of the Federal Reserve System.

          (y) The proceeds to the Issuers from the offering of the Offered 
Securities will be used as described in the Offering Document.

          (z) None of the Issuers, the Guarantors, any of their respective 
affiliates, or any director, officer, agent, employee or other person, in any 
case, acting on behalf of the Issuers or the Guarantors has (i) used any 
corporate funds for any unlawful contribution, gift, entertainment or other 
unlawful expense relating to political activity; (ii) made any direct or 
indirect unlawful payment to any foreign or domestic government official or 
employee from corporate funds; (iii) violated or is in violation of any 
provision of the Foreign Corrupt Practices Act of 1977; or (iv) made any 
bribe, rebate, payoff, influence payment, kickback or other unlawful payment.

          (aa) As of the Closing Date and after the application of the 
proceeds of the offering as described in the Offering Document, (i) the 
amounts held in the Interest Escrow Account will provide cash at such times 
and in such amounts as will be sufficient to pay, when due, interest on the 
Offered Securities for the first two semi-annual interest payment dates, and 
(ii) the amounts held in the Construction Escrow Account will provide cash at 
such times and in such amounts as will be sufficient, after giving effect to 
amounts paid prior to the Closing Date, cash on hand immediately prior to the 
Closing Date and borrowing availability under the Bank Facility to pay, when 
due, each installment payment for the Purchase Price (as defined in the 
Indenture) for each Rig as well as all expenses for owner furnished equipment 
and overhead allocable to such Rig prior to its Delivery Date, in each case 
as set forth in the table appearing in the Offering Document under the 
caption "Business - The Construction Contracts."

     3. Purchase, Sale and Delivery of Offered Securities. On the basis of 
the representations, warranties and agreements herein contained, but subject 
to the terms and conditions herein set forth, the Issuers agree to sell to 
the Purchasers, and the Purchasers agree, severally and not jointly, to 
purchase from the Issuers, at a purchase price of 97.25% of the principal 
amount thereof plus accrued interest from April 29, 1998 to the Closing Date 
(as hereinafter defined), the respective principal amounts of Securities set 
forth opposite the names of the several Purchasers in Schedule A hereto.

     The Issuers will deliver against payment of the purchase price the 
Offered Securities in the form of one or more permanent global Securities in 
registered form without interest coupons (the "Global Securities") which will 
be deposited with the Trustee as custodian for The Depository Trust Company 
("DTC") and registered in the name of Cede & Co., as nominee for DTC. 
Interests in any permanent global Securities will be held only in book-entry 
form through DTC, except in the limited circumstances described in the 
Offering Document. Payment for Offered Securities shall be made by the 
Purchasers in Federal (same day) funds by wire transfer to an account at a 
bank acceptable to CSFBC, at the office of Andrews & Kurth L.L.P., 425 
Lexington Avenue, New York, New York 10017, at 10:00 a.m. (New York time),

thereafter as CSFBC and the Company determine, such time being herein 
referred to as the "Closing Date", against delivery to the Trustee as

     5.  Certain Agreements of the Issuers and the Subsidiary Guarantors. The
Issuers and the Subsidiary Guarantors, jointly and severally, agree with the
several Purchasers that:

          (a) The Issuers and the Subsidiary Guarantors will advise CSFBC 
promptly of any proposal to amend or supplement the Offering Document and 
will not effect such amendment or supplementation without CSFBC's consent, 
nor to be unreasonably withheld. If, at any time prior to the completion of 
the resale of the Offered Securities by the Purchasers, any event occurs as a 
result of which the Offering Document as then amended or supplemented would 
include an untrue statement of a material fact or omit to state any material 
fact necessary in order to make the statements therein, in the light of the 
circumstances under which they were made, not misleading, the Issuers and the 
Subsidiary Guarantors promptly will notify CSFBC of such event and promptly

                                        9

<PAGE>

will prepare, at their own expense, an amendment or supplement which will 
correct such statement or omission. Neither CSFBC's consent to, nor the 
Purchasers' delivery to offerees or investors of, any such amendment or 
supplement shall constitute a waiver of any of the conditions set forth in 
Section 6.

          (b) The Issuers and the Subsidiary Guarantors will furnish to CSFBC 
copies of any preliminary offering circular, the Offering Document and all 
amendments and supplements to such documents, in each case as soon as 
available and in such quantities as CSFBC requests and, upon request, the 
Issuers and the Subsidiary Guarantors will furnish to CSFBC on the date 
hereof three copies of the Offering Document signed by a duly authorized 
officer of each of the Issuers and the Subsidiary Guarantors, one of which 
will include the independent accountants' reports therein manually signed by 
such independent accountants. At any time when the Issuers and the Subsidiary 
Guarantors are not subject to Section 13 or 15(d) of the Exchange Act, the 
Issuers and the Subsidiary Guarantors will promptly furnish or cause to be 
furnished to CSFBC (and, upon request, to each of the other Purchasers) and, 
upon request of holders and prospective purchasers of the Offered Securities, 
to such holders and purchasers, copies of the information required to be 
delivered to holders and prospective purchasers of the Offered Securities 
pursuant to Rule 144A(d)(4) under the Securities Act (or any successor 
provision thereto) in order to permit compliance with Rule 144A in connection 
with resales by such holders of the Offered Securities. The Company will pay 
the expenses of printing and distributing to the Purchasers all such 
documents.

          (c) The Issuers will arrange for the qualification of the Offered 
Securities for sale and the determination of their eligibility for investment 
under the laws of such jurisdictions in the United States and Canada as CSFBC 
designates and will continue such qualifications in effect so long as 
required for the resale of the Offered Securities by the Purchasers, provided 
that the Issuers and the Subsidiary Guarantors will not be required to 
qualify as a foreign corporation or to file a general consent to service of 
process in any such state or take any action that would subject it to general 
service of process or to taxation in any jurisdiction where it is not then so 
subject.

          (d) During the period of five years hereafter, the Company will 
furnish to CSFBC and, upon request, to each of the other Purchasers, as soon 
as practicable after the end of each fiscal year, a copy of its annual report 
to members for such year; and the Company will furnish to CSFBC and, upon 
request, to each of the other Purchasers (i) as soon as available, a copy of 
each report or financial statement furnished to or filed with the Commission 
or any securities exchange on which any class of securities of either of the 
Issuers is listed, and (ii) from time to time, such other information 
concerning the Company as CSFBC may reasonably request.

          (e) During the period of two years after the Closing Date, the 
Issuers will, upon request, furnish to CSFBC, each of the other Purchasers 
and any holder of Offered Securities a copy of the restrictions on transfer 
applicable to the Offered Securities.

          (f) During the period of two years after the Closing Date, neither 
the Issuers nor the Subsidiary Guarantors will, and they will not permit any 
of their affiliates (as defined in Rule 144

                                       10

<PAGE>

under the Securities Act) to, resell any of the Offered Securities that have 
been reacquired by any of them.

          (g) During the period of two years after the Closing Date, neither 
the Issuers nor the Subsidiary Guarantors will be or become, an open-end 
investment company, unit investment trust or face-amount certificate company 
that is or is required to be registered under Section 8 of the Investment 
Company Act.

          (h) The Issuers will pay all expenses incidental to the performance 
of their obligations under this Agreement, the Indenture, the Escrow 
Agreement and the Registration Rights Agreement, including (i) the fees and 
expenses of the Trustee and its professional advisers; (ii) all expenses in 
connection with the execution, issue, authentication, packaging and initial 
delivery of the Offered Securities, the preparation and printing of this 
Agreement, the Offered Securities, the Registration Rights Agreement and the 
Indenture, the Offering Document and amendments and supplements thereto, and 
any other document relating to the issuance, offer, sale and delivery of the 
Offered Securities; (iii) the cost of listing the Offered Securities and 
qualifying the Offered Securities for trading in The PortalSM Market 
("PORTAL") of the Nasdaq Stock Market, Inc. and any expenses incidental 
thereto; (iv) the cost of any advertising approved by the Company in 
connection with the issue of the Offered Securities; (v) for any expenses 
(including fees and disbursements of counsel) incurred in connection with 
qualification of the Offered Securities for sale under the laws of such 
jurisdictions in the United States and Canada as CSFBC designates and the 
printing of memoranda relating thereto; (vi) for any fees charged by 
investment rating agencies for the rating of the Securities, and (vii) for 
expenses incurred in distributing preliminary offering circulars and the 
Offering Document (including any amendments and supplements thereto) to the 
Purchasers. The Issuers will also pay or reimburse the Purchasers (to the 
extent incurred by them) for all air travel expenses and hotel accommodations 
of the Issuers' officers and employees and any other expenses of the Issuers 
in connection with attending or hosting meetings with prospective purchasers 
of the Offered Securities from the Purchasers.

          (i) In connection with the offering, until CSFBC shall have 
notified the Issuers and the other Purchasers of the completion of the resale 
of the Offered Securities, neither the Issuers nor any of their affiliates 
has or will, either alone or with one or more other persons, bid for or 
purchase for any account in which it or any of its affiliates has a 
beneficial interest any Offered Securities or attempt to induce any person to 
purchase any Offered Securities; and neither it nor any of its affiliates 
will make bids or purchases for the purpose of creating actual, or apparent, 
active trading in, or of raising the price of, the Offered Securities.

     6. Conditions of the Obligations of the Purchasers. The obligations of 
the several Purchasers to purchase and pay for the Offered Securities will be 
subject to the accuracy of the representations and warranties on the part of 
the Issuers and the Subsidiary Guarantors herein, to the accuracy of the 
statements of officers of the Issuers and the Subsidiary Guarantors made 
pursuant to the provisions hereof, to the performance by the Issuers and the 
Subsidiary Guarantors of their obligations hereunder and to the following 
additional conditions precedent:

          (a) The Purchasers shall have received a letter, dated the date of 
this Agreement, of Arthur Andersen LLP in form and substance satisfactory to 
the Purchasers concerning the financial information with respect to the 
Issuers and the Subsidiary Guarantors set forth in the Offering Document.

          (b) Subsequent to the execution and delivery of this Agreement, 
there shall not have occurred (i) a change in U.S. or international 
financial, political or economic conditions or currency exchange rates or 
exchange controls as would, in the judgment of CSFBC, be likely to prejudice 
materially the success of the proposed issue, sale or distribution of the 
Offered Securities, whether in the primary market or in respect of dealings 
in the secondary market, or (ii) (A) any change, or any development or event 
involving a prospective change, in the condition (financial or other), 
business, properties or results of operations of the Issuers and the 
Subsidiary Guarantors which, in the judgment of a majority in interest of the 
Purchasers including CSFBC, is material and adverse and makes it impractical 
or inadvisable to proceed with completion of the offering or the sale of and 
payment for the Offered Securities; (B) any downgrading in the rating of any 
debt securities of the Company by any "nationally recognized statistical 
rating organization" (as defined for purposes of Rule 436(g) under the 
Securities Act), or any public announcement that any such organization has 
under surveillance or review its rating of any debt securities of the Company 
(other than an announcement with positive implications of a possible 
upgrading, and no implication of a possible downgrading, of such rating); (C) 
any suspension or limitation of trading in securities generally on the New 
York Stock Exchange; (D) any banking moratorium declared by U.S. Federal or 
New York authorities; or (E) any outbreak or escalation of major hostilities 
in which the United States is involved, any declaration of war by Congress or 
any other substantial national or international calamity or emergency if, in 
the judgment of a majority in interest of the Purchasers including CSFBC, the 
effect of any such outbreak, escalation, declaration, calamity or emergency 
makes it impractical or inadvisable to proceed with completion of the 
offering or sale of and payment for the Offered Securities.

     authorized; the Offered Securities have been duly authorized for 
     issuance; and when the Offered Securities are delivered and paid for

     valid and legally binding obligations of the Issuers and the Subsidiary 
     Guarantors, as the case may be, enforceable in accordance with their 
     terms, subject to bankruptcy, insolvency, fraudulent conveyance, 
     reorganization, moratorium and similar laws of general applicability 
     relating to or affecting creditors' rights and remedies and to general 
     equity principles, including principles of commercial reasonableness,

     defined in the Investment Company Act.

               (vi) No consent, approval, authorization or order of, or

     federal governmental authority is required for the consummation of the 
     transactions contemplated by this Agreement and the Registration Rights 
     Agreement in connection with the issuance or sale of the Offered 
     Securities by the Issuers, or for the execution, delivery and 
     performance of the Indenture and the Escrow Agreement, except such as 
     may be required under state securities laws and except for such filings 
     with the Commission as are required in connection with the Registration 
     Rights Agreement, as to all of which such counsel need express no 
     opinion.

               (vii) The execution, delivery and performance of the 
     Indenture, this Agreement, the Registration Rights Agreement, the Escrow 
     Agreement and the Escrow Security Agreement and the issuance and sale of

     the terms and provisions thereof will not conflict with or constitute a 
     default under, or violate any New York, Texas, Delaware corporate or 
     United States federal statute, any rule, regulation or order of any New 
     York, Texas, Delaware corporate or United States federal governmental 
     authority having jurisdiction over the Issuers or the Subsidiary 
     Guarantors of which such counsel is aware (other than state securities 
     or "blue sky" law, rules and regulations, as to which such counsel need 
     not express any opinion in this paragraph), or any agreement or 
     instrument (including, without limitation, the Bank Facility (as defined 
     in the Offering Document)) to which the Issuers or the Subsidiary 
     Guarantors is a party or by which the Issuers or the Subsidiary

     of Finance or the Operating Agreement of each of the Subsidiary 
     Guarantors; and the Issuers have full power and authority to authorize, 
     issue and sell the Offered Securities as contemplated by this Agreement.

     Agreement and the proceeds thereof, compliance with the provisions of 
     the Escrow Agreement and the Escrow Security Agreement and the other 
     requirements set forth in such opinion, no further action is required be 
     taken under or pursuant to the laws of the State of Minnesota in order 
     to perfect such security interest therein. Such counsel need express no 
     opinion as to the priority of any such security interest referred to in 
     this paragraph.

               (ix) The descriptions in the Offering Document under the 
     captions "Business," "Management," "Principal Members," "Controlling 
     Member," "Certain Relationships and Related Transactions," "Description 
     of Bank Facility" and "Description of the Notes" insofar as they 
     describe the provisions of documents and instruments therein described, 
     constitute fair summaries thereof, and are accurate in all material 
     respects; the statements in the Offering Document under the caption 
     "Business--Governmental Regulation," insofar as they purport to describe 
     federal environmental laws of the United States, fairly present in all 
     material respects the information set forth therein; and the statements 
     in the Offering Document under the caption "Certain United States 
     Federal Income Tax Consequences to Non-U.S. Holders," insofar as they 
     purport to describe federal income tax laws of the United States, fairly 
     present in all material respects the information set forth therein; it 
     being understood that such counsel need express no opinion as to the 
     financial statements, the financial forecast or other financial or 
     statistical data contained in the Offering Document. Insofar as such 
     opinion covers federal environmental laws of the United States, such 
     counsel may rely solely upon the opinion of Gardere Wynne Sewell & Riggs 
     L.L.P.

               (x) Each of this Agreement and the Registration Rights 
     Agreement has been duly authorized, executed and delivered by the 
     Issuers and the Subsidiary Guarantors.

               (xi) Each of the Escrow Agreement and the Escrow Security 
     Agreement has been duly authorized, executed and delivered by the 
     Issuers; the Escrow Agreement will conform to the description thereof 
     contained in the Offering Document and each of the Escrow Agreement and 
     the Escrow Security Agreement will constitute a valid and legally 
     binding obligation of the Issuers, enforceable in accordance with its 
     terms, subject to bankruptcy, insolvency, fraudulent conveyance, 
     reorganization, moratorium and similar laws of general applicability 
     relating to or affecting creditors' rights and remedies and to general 
     equity principles, including principles of commercial reasonableness, 
     good faith and fair dealing (regarding of whether a proceeding is sought 
     at law or in equity).

               (xii) It is not necessary in connection with (A) the offer, 
     sale and delivery of the Offered Securities by the Issuers to the 
     several Purchasers pursuant to this Agreement or (B) the resales of the 
     Offered Securities by the several Purchasers in the manner contemplated 
     by this Agreement and the Offering Document, to register the Offered 
     Securities under the Securities Act or to qualify an indenture in 
     respect thereof under the Trust Indenture Act.

          In rendering such opinion, such counsel may rely (A) as to matters 
     involving the application of laws of any jurisdiction other than the 
     State of New York, the State of Texas or the United States or the 
     corporation law and limited liability company law of the State of 
     Delaware, to the extent they deem proper and specified in such opinion, 
     upon the opinion of other counsel of good standing whom they believe to 
     be reliable and who are satisfactory to counsel for the Purchasers and 
     (B) as to matters of fact, to the extent they deem proper, on

                                       15

<PAGE>

     certificates of responsible officers of the Company and public 
     officials. References to the Offering Document in this paragraph (c) 
     include any supplements thereto on or prior to the Closing Date.

          In addition to the foregoing, such counsel shall state that it has 
     participated in conferences with directors, executive officers and other 
     representatives of the Company, representatives of the Purchasers and 
     their counsel and representatives of the Company's independent public 
     accountants, at which conferences the contents of the Offering Document 
     and related matters were discussed, and although such counsel has not 
     independently verified and has not passed upon or assumed any 
     responsibility for the accuracy, completeness or fairness of the 
     statements contained in such documents (except to the extent set forth 
     in paragraph (ix) above), no facts have come to such counsel's attention 
     to lead it to believe that the Offering Document and any further 
     amendments or supplements thereto as of their respective dates and on 
     the date of such opinion letter contained or contains an untrue 
     statement of a material fact or omitted or omits to state a material 
     fact required to be stated therein, or necessary to make the statements 
     therein, in light of the circumstances under which they were made, not 
     misleading (it being understood that such counsel need not express any 
     view with respect to the financial statements and related notes, the 
     financial statement schedules, the financial forecasts and the other 
     financial, statistical and accounting data included in the Offering 
     Document).

          (d) The Purchasers shall have received from Andrews & Kurth L.L.P., 
counsel for the Purchasers, such opinion, dated the Closing Date, with 
respect to the formation of the Issuers and the Subsidiary Guarantors, the 
validity of the Offered Securities, the Offering Document, the exemption from 
registration for the offer and sale of the Offered Securities by the Issuers 
to the several Purchasers and the resales by the several Purchasers as 
contemplated hereby and other related matters as CSFBC may require, and the 
Issuers and the Subsidiary Guarantors shall have furnished to such counsel 
such documents as they request for the purpose of enabling them to pass upon 
such matters.

          (e) The Purchasers shall have received a certificate, dated the 
Closing Date, of the President or any Vice President and a principal 
financial or accounting officer of each of the Issuers and the Subsidiary 
Guarantors in which such officers, to the best of their knowledge after 
reasonable investigation, shall state that the representations and warranties 
of the applicable party in this Agreement are true and correct, that the 
applicable party has complied with all agreements and satisfied all 
conditions on its part to be performed or satisfied hereunder at or prior to 
the Closing Date, and that, subsequent to the date of the most recent 
financial statements in the Offering Document there has been no material 
adverse change, nor any development or event involving a prospective material 
adverse change, in the condition (financial or other), business, properties 
or results of operations of the Issuers and Subsidiary Guarantors taken as a 
whole except as set forth in or contemplated by the Offering Document or as 
described in such certificate. Such certificate from such officer of Finance 
further shall attach a balance sheet of Finance as of a recent date and 
certify that such balance sheet presents fairly the financial position of 
Finance as of such date in

                                       16

<PAGE>

conformity with generally accepted accounting principles in the United States 
and further certify that Finance had as of such date and has as of the 
Closing Date no liabilities (other than, as of the Closing Date, the Notes).

          (f) The Purchasers shall have received a letter, dated the Closing 
Date, of Arthur Andersen LLP which meets the requirements of subsection (a) 
of this Section, except that the specified date referred to in such 
subsection will be a date not more than three business days prior to the 
Closing Date for the purposes of this subsection. In the event the Issuers 
shall elect to deposit into the Interest Escrow Account any Temporary Cash 
Investments rather than cash only in the aggregate amount of the first two 
semi-annual interest payments, the Purchasers also shall have received from 
Arthur Andersen LLP a letter which shall certify that as of the Closing Date 
and after the application of the proceeds of the Offering as described in the 
Offering Document, the amounts held in the Interest Escrow Account will 
provide cash at such times and in such amounts as will be sufficient to pay, 
when due, interest on the Offered Securities for the first two semi-annual 
interest payment dates.

          (g) The Offered Securities shall have been made eligible for 
trading in PORTAL.

          (h) Each of the Construction Contracts and the binder for the 
"delay-in-delivery" insurance policy relating to the Rigs described in the 
Offering Document shall be in full force and effect, and no default or event 
that with notice, a lapse of time, or both, would constitute a default, shall 
exist thereunder.

          (i) The Company shall have entered into the Bank Facility and no 
default or event that with notice, a lapse of time, or both, would constitute 
a default, shall exist thereunder.

          (j) The Issuers shall have entered into the Escrow Agreement and no 
default or event that with notice, a lapse of time, or both would constitute 
a default, shall exist thereunder. Concurrently with the Closing, the 
aggregate net proceeds of the Offered Securities shall have been deposited in 
the Escrow Accounts.

     The Issuers will furnish the Purchasers with such conformed copies of 
such opinions, certificates, letters and documents as the Purchasers 
reasonably request. CSFBC may in its sole discretion waive on behalf of the 
Purchasers compliance with any conditions to the obligations of the 
Purchasers hereunder, whether in respect of the Closing Date or otherwise.

     7. Indemnification and Contribution. (a) The Issuers and the Subsidiary 
Guarantors , jointly and severally, will indemnify and hold harmless each 
Purchaser against any losses, claims, damages or liabilities, joint or 
several, to which such Purchaser may become subject, under the Securities Act 
or the Exchange Act or otherwise, insofar as such losses, claims, damages or 
liabilities (or actions in respect thereof) arise out of or are based upon 
any breach of any of the representations and warranties of the Issuers and 
the Subsidiary Guarantors contained herein or any untrue statement or alleged 
untrue statement of any material fact contained in the Offering Document, or 
any

                                       17

<PAGE>

amendment or supplement thereto, or any related preliminary offering 
circular, or arise out of or are based upon the omission or alleged omission 
to state therein a material fact necessary in order to make the statements 
therein, in the light of the circumstances under which they were made, not 
misleading, and will reimburse each Purchaser for any legal or other expenses 
reasonably incurred by such Purchaser in connection with investigating or 
defending any such loss, claim, damage, liability or action as such expenses 
are incurred; provided, however, that the Issuers and the Subsidiary 
Guarantors will not be liable in any such case to the extent that any such 
loss, claim, damage or liability arises out of or is based upon an untrue 
statement or alleged untrue statement in or omission or alleged omission from 
any of such documents in reliance upon and in conformity with written 
information furnished to the Company by any Purchaser through CSFBC 
specifically for use therein, it being understood and agreed that the only 
such information consists of the information described as such in subsection 
(b) below.

          (b) Each Purchaser will severally and not jointly indemnify and 
hold harmless the Issuers and the Subsidiary Guarantors against any losses, 
claims, damages or liabilities to which the Issuers and the Subsidiary 
Guarantors may become subject, under the Securities Act or the Exchange Act 
or otherwise, insofar as such losses, claims, damages or liabilities (or 
actions in respect thereof) arise out of or are based upon any untrue 
statement or alleged untrue statement of any material fact contained in the 
Offering Document, or any amendment or supplement thereto, or any related 
preliminary offering circular, or arise out of or are based upon the omission 
or the alleged omission to state therein a material fact necessary in order 
to make the statements therein, in the light of the circumstances under which 
they were made, not misleading, in each case to the extent, but only to the 
extent, that such untrue statement or alleged untrue statement or omission or 
alleged omission was made in reliance upon and in conformity with written 
information furnished to the Issuers by such Purchaser through CSFBC 
specifically for use therein, and will reimburse any legal or other expenses 
reasonably incurred by the Issuers and the Subsidiary Guarantors in 
connection with investigating or defending any such loss, claim, damage, 
liability or action as such expenses are incurred, it being understood and 
agreed that the only such information furnished by any Purchaser consists of 
the following information in the Offering Document furnished on behalf of 
each Purchaser: the last paragraph at the bottom of the cover page concerning 
the terms of the offering by the Purchasers, the legend concerning 
over-allotments and stabilizing on the inside front cover page and paragraph 
seven under the caption "Plan of Distribution."

          (c) Promptly after receipt by an indemnified party under this 
Section of notice of the commencement of any action, such indemnified party 
will, if a claim in respect thereof is to be made against the indemnifying 
party under subsection (a) or (b) above, notify the indemnifying party of the 
commencement thereof; but the omission so to notify the indemnifying party 
will not relieve it from any liability which it may have to any indemnified 
party (except to the extent that a defense or counterclaim thereto has been 
foreclosed thereby) otherwise than under subsection (a) or (b) above. In case 
any such action is brought against any indemnified party and it notifies the 
indemnifying party of the commencement thereof, the indemnifying party will 
be entitled to participate therein and, to the extent that it may wish, 
jointly with any other indemnifying party similarly notified, to assume the 
defense thereof, with counsel satisfactory to such indemnified party

                                       18

<PAGE>

(who shall not, except with the consent of the indemnified party, be counsel 
to the indemnifying party), and after notice from the indemnifying party to 
such indemnified party of its election so to assume the defense thereof, the 
indemnifying party will not be liable to such indemnified party under this 
Section for any legal or other expenses subsequently incurred by such 
indemnified party in connection with the defense thereof other than 
reasonable costs of investigation. No indemnifying party shall, without the 
prior written consent of the indemnified party, effect any settlement of any 
pending or threatened action in respect of which any indemnified party is or 
could have been a party and indemnity could have been sought hereunder by 
such indemnified party unless such settlement includes an unconditional 
release of such indemnified party from all liability on any claims that are 
the subject matter of such action.

          (d) If the indemnification provided for in this Section is 
unavailable or insufficient to hold harmless an indemnified party under 
subsection (a) or (b) above, then each indemnifying party shall contribute to 
the amount paid or payable by such indemnified party as a result of the 
losses, claims, damages or liabilities referred to in subsection (a) or (b) 
above (i) in such proportion as is appropriate to reflect the relative 
benefits received by the Issuers and Subsidiary Guarantors on the one hand 
and the Purchasers on the other from the offering of the Offered Securities 
or (ii) if the allocation provided by clause (i) above is not permitted by 
applicable law, in such proportion as is appropriate to reflect not only the 
relative benefits referred to in clause (i) above but also the relative fault 
of the Issuers and the Subsidiary Guarantors on the one hand and the 
Purchasers on the other in connection with the statements or omissions which 
resulted in such losses, claims, damages or liabilities as well as any other 
relevant equitable considerations. The relative benefits received by the 
Issuers and the Subsidiary Guarantors on the one hand and the Purchasers on 
the other shall be deemed to be in the same proportion as the total net 
proceeds from the offering (before deducting expenses) received by the 
Issuers and the Subsidiary Guarantors bear to the total discounts and 
commissions received by the Purchasers from the Issuers and the Subsidiary 
Guarantors under this Agreement. The relative fault shall be determined by 
reference to, among other things, whether the untrue or alleged untrue 
statement of a material fact or the omission or alleged omission to state a 
material fact relates to information supplied by the Issuers and the 
Subsidiary Guarantors or the Purchasers and the parties' relative intent, 
knowledge, access to information and opportunity to correct or prevent such 
untrue statement or omission. The amount paid by an indemnified party as a 
result of the losses, claims, damages or liabilities referred to in the first 
sentence of this subsection (d) shall be deemed to include any legal or other 
expenses reasonably incurred by such indemnified party in connection with 
investigating or defending any action or claim which is the subject of this 
subsection (d). Notwithstanding the provisions of this subsection (d), no 
Purchaser shall be required to contribute any amount in excess of the amount 
by which the total price at which the Offered Securities purchased by it were 
resold exceeds the amount of any damages which such Purchaser has otherwise 
been required to pay by reason of such untrue or alleged untrue statement or 
omission or alleged omission. No person guilty of fraudulent 
misrepresentation within the meaning of Section 11(f) of the Securities Act) 
shall be entitled to contribution from any person who was not guilty of such 
fraudulent misrepresentation. The Purchasers' obligations in this subsection 
(d) to contribute are several in proportion to their respective purchase 
obligations and not joint.

                                       19

<PAGE>

          (e) The obligations of the Issuers and the Subsidiary Guarantors 
under this Section shall be in addition to any liability which the Issuers 
and the Subsidiary Guarantors may otherwise have and shall extend, upon the 
same terms and conditions, to each person, if any, who controls any Purchaser 
within the meaning of the Securities Act or the Exchange Act; and the 
obligations of the Purchasers under this Section shall be in addition to any 
liability which the respective Purchasers may otherwise have and shall 
extend, upon the same terms and conditions, to each person, if any, who 
controls the Issuers and the Subsidiary Guarantors within the meaning of the 
Securities Act or the Exchange Act.

     8. Default of Purchasers. If any Purchaser or Purchasers default in 
their obligations to purchase Offered Securities hereunder and the aggregate 
amount of Offered Securities that such defaulting Purchaser or Purchasers 
agreed but failed to purchase does not exceed 10% of the total principal 
amount of Offered Securities, CSFBC may make arrangements satisfactory to the 
Issuers and the Subsidiary Guarantors for the purchase of such Offered 
Securities by other persons, including any of the Purchasers, but if no such 
arrangements are made by such Closing Date, the non-defaulting Purchasers 
shall be obligated severally, in proportion to their respective commitments 
hereunder, to purchase the Offered Securities that such defaulting Purchasers 
agreed but failed to purchase. If any Purchaser or Purchasers so default and 
the aggregate principal amount of Offered Securities with respect to which 
such default or defaults occur exceeds 10% of the total principal amount of 
Offered Securities and arrangements satisfactory to CSFBC and the Issuers and 
the Subsidiary Guarantors for the purchase of such Offered Securities by 
other persons are not made within 36 hours after such default, this Agreement 
will terminate without liability on the part of any non-defaulting Purchaser 
or the Issuers and the Subsidiary Guarantors, except as provided in Section 
9. As used in this Agreement, the term "Purchaser" includes any person 
substituted for a Purchaser under this Section. Nothing herein will relieve a 
defaulting Purchaser from liability for its default.

     9. Survival of Certain Representations and Obligations. The respective 
indemnities, agreements, representations, warranties and other statements of 
the Issuers and the Subsidiary Guarantors or its officers and of the several 
Purchasers set forth in or made pursuant to this Agreement will remain in 
full force and effect, regardless of any investigation, or statement as to 
the results thereof, made by or on behalf of any Purchaser, the Issuers and 
the Subsidiary Guarantors or any of their respective officers or directors or 
any controlling person, and will survive delivery of and payment for the 
Offered Securities. If this Agreement is terminated pursuant to Section 8 or 
if for any reason the purchase of the Offered Securities by the Purchasers is 
not consummated, the Issuers and the Subsidiary Guarantors shall remain 
responsible for the expenses to be paid or reimbursed by them pursuant to 
Section 5 and the respective obligations of the Issuers and the Subsidiary 
Guarantors and the Purchasers pursuant to Section 7 shall remain in effect. 
If the purchase of the Offered Securities by the Purchasers is not 
consummated for any reason other than solely because of the termination of 
this Agreement pursuant to Section 8 or the occurrence of any event specified 
in clause (C), (D) or (E) of Section 6(b)(ii), the Issuers and the Subsidiary 
Guarantors will reimburse the Purchasers for all out-of-pocket expenses 
(including fees and disbursements of counsel) reasonably incurred by them in 
connection with the offering of the Offered Securities.

     11. Successors. This Agreement will be binding upon the parties hereto 
and their respective successors, and will inure to the benefit of the parties 
hereto and their respective successors, and the controlling persons referred 
to in Section 7, and no other person will have any right or obligation 
hereunder, except that holders of Offered Securities shall be entitled to 
enforce the agreements for their benefit contained in the second and third 
sentences of Section 5(b) hereof against the Issuers and the Subsidiary 
Guarantors as if such holders were parties thereto.

     12. Representation of Purchasers. You will act for the several 
Purchasers in connection with this purchase, and any action under this 
Agreement taken by you jointly or by CSFBC will be binding upon all the 
Purchasers.

     13. Counterparts. This Agreement may be executed in any number of 
counterparts, each of which shall be deemed to be an original, but all such 
counterparts shall together constitute one and the same Agreement.

     14. Applicable Law. This Agreement shall be governed by, and construed 
in accordance with, the laws of the State of New York without regard to 
principles of conflicts of laws.

     Each of the Issuers and the Subsidiary Guarantors hereby submits to the 
non-exclusive jurisdiction of the Federal and state courts in the Borough of 
Manhattan in The City of New York in any suit or proceeding arising out of or

4.3 Breakfunding Costs. In the event that, on any date specified for the making
of an Advance in any Drawdown Notice, the Lenders shall not be obliged under

5        REPAYMENT, REDUCTION AND PREPAYMENT

5.1 Repayment. The Borrower shall repay all outstanding Advances (subject to
such reduction and prepayments as hereinafter set forth) on the Maturity Date.

5.2 Prepayment; Reborrowing. The Borrower may prepay, upon five (5) Banking Days
written notice, any outstanding Advance or any portion thereof, without penalty,
provided that such prepayment is made on the last day of the Interest Period of
such Advance. Each prepayment shall be in a minimum amount of One Million
Dollars ($1,000,000) plus any One Million Dollar ($1,000,000) multiples thereof
or the full amount of the Advance. Subject to the limits and upon the conditions
herein provided, the Borrower may from time to time prepay the Advances and
thereafter re-borrow such Advances or a portion thereof.

5.3 Optional Permanent Reduction of Credit Facility. The Borrower shall have the
right, at any time and from time to time, to request, without penalty, a
permanent reduction in the Credit Facility, provided (a) that the Administrative
Agent receives five (5) Banking Days prior written notice of such request and
(b), in the case of drawn amounts under the Credit Facility, that such requested
reduction occurs on the last day of the applicable Interest Period(s). Each such
partial permanent reduction shall be equal to or shall exceed Two Million Five
Hundred Thousand Dollars ($2,500,000) and multiples thereof.

5.4 Interest and Costs with Prepayments. Any prepayment of the Advances made
hereunder shall be subject to the condition that on the date of prepayment all
accrued interest to the date of such prepayment shall be paid in full with
respect to the Advances or portions thereof being prepaid, together with any and
all actual costs or expenses incurred by any Lender in connection with any
breaking of funding (as certified by such Lender, which certification shall,
absent any manifest error, be conclusive and binding on the Borrower).

6.       INTEREST AND RATE

6.1 Applicable Rate; Default Rate. Each Advance shall bear interest at the
Applicable Rate which shall be the rate per annum which is equal to the
aggregate of (a) LIBOR for the relevant Interest Period plus (b) the Margin. The
Applicable Rate with respect to each Advance shall be determined by the
Administrative Agent two Banking Days prior to the first day of the relevant
Interest Period and the Borrower shall be promptly notified in writing thereof,
such determination of each such Applicable Rate, absent manifest error, to be
conclusive and binding upon the Borrower. Any amounts due under this Agreement
not paid when due, whether by acceleration or otherwise, shall bear 


                                       24
<PAGE>


interest thereafter until paid at a rate per annum of two percent (2%) over the
Applicable Rate in effect with respect to such payment at the time of such
default (the "Default Rate").

6.2 Interest Periods. With respect to each Advance, the Borrower may select
Interest Periods of one, three or six months. The Borrower shall give the
Administrative Agent an Interest Notice specifying the Interest Period selected
at least three (3) Banking Days prior to the end of any then existing Interest
Period. If at the end of any then existing Interest Period the Borrower fails to
give an Interest Notice the relevant Interest Period shall be three (3) months.
The Borrower's right to select an Interest Period shall be subject to the
restriction that no selection of an Interest Period shall be effective unless
the Administrative Agent is satisfied that the necessary funds will be available
to the Lenders for such period and that no Event of Default or event which, with
the giving of notice or lapse of time, or both, would constitute an Event of
Default shall have occurred and be continuing.

6.3 Interest Payments. Accrued interest on each Advance shall be payable in
arrears on the last day of each Interest Period, except that if the Borrower
shall select an Interest Period in excess of three (3) months, accrued interest
shall be payable during such Interest Period on each three (3) month anniversary
of the commencement of such Interest Period and upon the end of such Interest
Period.

6.4 Payment on Banking Day. If interest would, under Section 6.3, be payable on
a day which is not Banking Day, it shall then be payable on the next following
Banking Day unless such next following Banking Day falls in the following
calendar month, in which case interest shall be payable on the immediately
preceding Banking Day.

6.5 Calculation of Interest. All interest shall accrue and be calculated on the
actual number of days lapsed and on the basis of a three hundred sixty (360) day
year.

7.       PAYMENTS

7.1 Place of Payments, No Set Off. All payments to be made hereunder by the
Borrower shall be made to the Administrative Agent, not later than 11 a.m. New
York time (any payment received after 11 a.m. New York time shall be deemed to
have been paid on the next Banking Day) on the due date of such payment, at its
office located at 3 Stamford Plaza, 301 Tresser Boulevard, Stamford, Connecticut
or to such other office of the Administrative Agent as the Administrative Agent
may direct, without set-off or counterclaim and free from, clear of, and without
deduction for, any Taxes, provided, however, that if the Borrower shall at any
time be compelled by law to withhold or 


                                       25
<PAGE>


deduct any Taxes from any amounts payable to the Lenders hereunder, then the
Borrower shall pay such additional amounts in Dollars as may be necessary in
order that the net amounts received after withholding or deduction shall equal
the amounts which would have been received if such withholding or deduction were
not required and, in the event any withholding or deduction is made, whether for
Taxes or otherwise, the Borrower shall promptly send to the Administrative Agent
such documentary evidence with respect to such withholding or deduction as may
be required from time to time by the Lenders.

7.2 Proof of Withholding. Each Lender and any transferee, assignee or
participation holder (a "Transferee") that is not incorporated under the laws of
the United States of America or a State thereof agrees that, on the initial
Drawdown Date and prior to the first date on which any payment is due to such
Lenders hereunder, such Lenders will deliver to the Borrower (i) two duly
completed copies of United States Internal Revenue Service Form 1001 or 4224, or
successor applicable form, as the case may be, certifying in each case that the
Lender or Transferee is entitled to receive payments under this Agreement and
the Notes without deduction or withholding of any United States Federal income
taxes and (ii) a United States Internal Revenue Service Form W-8 or W-9, or
successor applicable form, as the case may be, to establish an exemption from
United States backup withholding tax. Such Lender or Transferee which delivers
to the Borrower a Form 1001 or 4224 and Form W-8 or W-9 pursuant to the
preceding sentence further undertakes to deliver to the Borrower two further
copies of said Form 1001 or 4224 and Form W-8 or W-9, or successor applicable
forms, or other manner of certification, as the case may be, on or before the
date that any such form expires or becomes obsolete or after the occurrence of
any event requiring a change in the most recent form previously delivered
thereby to the Borrower and such extensions or renewals thereof as may
reasonably be requested by the Borrower certifying in the case of a Form 1001 or
4224 that such Lender or such Transferee is entitled to receive payments under
this Agreement and the Note without deduction or withholding of any United
States Federal income taxes, unless in any such case an event (including,
without limitation, any change in treaty, law or regulation) has occurred prior
to the date on which any such delivery would otherwise be required which renders
all such forms inapplicable or which would prevent such Lender or such
Transferee from duly completing and delivering any such letter or form with
respect to it, and such Lender or such Transferee advised the Borrower that it
is not capable of (i) receiving payments without any deduction or withholding of
United States Federal income tax, and (ii) in the case of a Form W-8 or W-9,
establishing an exemption from United States backup withholding tax.

7.3 Tax Credits. If any Lender obtains the benefit of a credit against the
liability thereof for federal income taxes imposed by any taxing authority for
all or part of the Taxes as to which the Borrower has paid additional amounts as
aforesaid, then such Lender shall reimburse the Borrower for the amount of the
credit so obtained.

8.1 In the event that any of the following events shall occur and be continuing:

                  (a) Non-Payment of Principal. Any payment of principal due on
the Maturity Date is not paid on the Maturity Date or is not prepaid in

Documents is not paid within three (3) Banking Days of the due date or date of
demand (as the case may be); or

                  (c) Representations. Any representation, warranty or other
statement made by the Borrower in this Agreement or by any Security Party in the
Guaranty or in any of the Security Documents or in any other instrument,
document or other agreement delivered in connection herewith or therewith proves
to have been untrue or misleading in any material respect as at the date as of
which made or confirmed; or

                  (d) Mortgage.  There is an event of default under either
Mortgage; or

                  (e) Covenants. Any Security Party defaults in the due and
punctual observance or performance of any other term, covenant or agreement
contained in the Indenture, this Agreement, in the Note, in the Guaranty, in any
of the Security Documents or in any other instrument, document or other
agreement delivered in connection herewith or therewith, or it becomes
impossible or unlawful for any Security Party to fulfill any such term, covenant
or agreement or there occurs any other event which constitutes a default under
this Agreement, under the Note, under the Guaranty or under any of the Security
Documents, in each case other than an Event of Default referred to elsewhere in
this Section 8.1, and such default, impossibility and/or unlawfulness, in the
reasonable opinion of the Majority Lenders, could have a material adverse effect
on the Lenders' rights hereunder, under the Note, under the Guaranty and/or
under the Security Documents or on the Lenders' right to enforce this Agreement,
the Note, the Guaranty and/or the Security Documents and such default is not
cured by the Borrower within thirty (30) days of the occurrence of such default;
or

                  (f) Indebtedness. Any Security Party, any Subsidiary or any
Affiliate shall default in the payment when due (subject to any applicable grace
period) of any Indebtedness or of any other indebtedness, in either case, in the

                                       27
<PAGE>


amount equal to or exceeding One Million Dollars ($1,000,000) or such
Indebtedness or indebtedness is, or by reason of such default is subject to
being, accelerated or any party becomes entitled to enforce the security for any
such Indebtedness or indebtedness and such party shall take steps to enforce the
same, unless such default or enforcement is being contested in good faith and by
appropriate proceedings or other acts and the Security Party, Subsidiary or
Affiliate, as the case may be, shall set aside on its books adequate reserves
with respect thereto; provided, however, that the provisions of this paragraph
(f) shall not apply to any indebtedness of the Borrower which is non-recourse to
the Borrower, any Security Party or any Unit; or

                  (g) Indenture Default.  An event of default under the 
Indenture shall have occurred and be continuing;

                  (h) Equity Ownership. The Borrower shall cease to own (except
as otherwise expressly permitted by this Agreement), directly or indirectly, one
hundred percent (100%) of any of the other Security Parties, and in any such
case the Majority Lenders have not prior thereto consented in writing to such
change; or

                  (i) Bankruptcy. The Borrower or any Affiliate commences any
proceeding under any reorganization, arrangement or readjustment of debt,
dissolution, winding up, adjustment, composition, bankruptcy or liquidation law
or statute of any jurisdiction, whether now or hereafter in effect
("Proceeding"), or there is commenced against any thereof any Proceeding and
such Proceeding remains undismissed or unstayed for a period of sixty (60) days
or any receiver, trustee, liquidator or sequestrator of, or for, any thereof or
any substantial portion of the property of any thereof is appointed and is not
discharged within a period of sixty (60) days or any thereof by any act
indicates consent to or approval of or acquiescence in any Proceeding or the

itself or of, or for, any substantial portion of its property; or

                  (j) Termination of Operations; Sale of Assets. Except as
expressly permitted under this Agreement, any Security Party ceases its
operations or sells or otherwise disposes of all or substantially all of its
assets or all or substantially all of the assets of any Security Party are
seized or otherwise appropriated (subject to the provisions hereof and of the
Security Documents respecting in rem proceedings); or

                  (k) Judgments. Any judgment or order is made the effect
whereof would be to render ineffective or invalid this Agreement, the Note, the
Guaranty or any of the Security Documents; or


                                       28
<PAGE>


                  (l) Inability to Pay Debts. Any Security Party is unable to
pay or admits its inability to pay its debts as they fall due or a moratorium
shall be declared in respect of any material indebtedness of any Security Party;
or

                  (m) Change in Control. A Change of Control shall occur with
respect to the Borrower;

then the Lenders' obligation to make any Advance available shall cease and the
Administrative Agent on the instructions of the Majority Lenders may, by notice
to the Borrower, declare the entire unpaid balance of the then outstanding
Advances, accrued interest and any other sums payable by the Borrower hereunder
or under the Note due and payable, whereupon the same shall forthwith be due and
payable without presentment, demand, protest or notice of any kind, all of which
are hereby expressly waived; provided that upon the happening of an event
specified in subsections (i) or (l) of this Section 8.1 with respect to the
Borrower, the Note shall be immediately due and payable without declaration or
other notice to the Borrower. In such event, the Lenders (or the Security
Trustee acting at the direction of the Lenders) may proceed to protect and
enforce their rights by action at law, suit in equity or in admiralty or other
appropriate proceeding, whether for specific performance of any covenant
contained in this Agreement, in the Note, in the Guaranty or in any Security
Document, or in aid of the exercise of any power granted herein or therein, or
the Lenders may proceed to enforce the payment of the Note or to enforce any
other legal or equitable right of the Lenders, or proceed to take any action
authorized or permitted under the terms of the Guaranty or any Security Document
or by applicable law for the collection of all sums due, or so declared due, on
the Note, including, without limitation, the right to appropriate and hold or
apply (directly, by way of set-off or otherwise) to the payment of the
obligations of the Borrower to the Lenders hereunder and/or under the Note
(whether or not then due) all moneys and other amounts of the Borrower then or
thereafter in possession of any Lender, the balance of any deposit account
(demand or time, mature or unmatured) of the Borrower then or thereafter with
any Lender and every other claim of the Borrower then or thereafter against any
of the Lenders. Notwithstanding anything herein to the contrary, upon the
occurrence of an event which with the giving of notice or the passage of time or
both would constitute an Event of Default, the Lenders will grant the note
holders under the Indenture and/or the Borrower a one time only opportunity to
cure such default expiring on the earlier of (i) the date which is 60 days from
and after the date on which the Administrative Agent shall give the Trustee and
the Borrower written notice of such default, and (ii) the Administrative Agent's
receipt of written notice from the Trustee indicating that such note holders do
not wish to exercise such cure right; provided, however, that such cure period
shall not be applicable if (i) the Borrower defaults under any other
Indebtedness and the holder thereof takes steps to enforce same, (ii) any party
seeks to enforce any in rem claim against either Unit which is not released
within five (5) days by posting of 


                                       29
<PAGE>


appropriate security or otherwise, or (iii) the Borrower or either Guarantor
becomes the subject of a bankruptcy proceeding.

Creditors harmless against any loss, as well as against any costs or expenses
(including legal fees and expenses), which any of the Creditors sustains or
incurs as a consequence of any default in payment of the principal amount of the
Advances, interest accrued thereon or any other amount payable hereunder, under
the Note, under the Guaranty or under any Security Documents including, but not
limited to, all actual losses incurred in liquidating or re-employing fixed
deposits made by third parties or funds acquired to effect or maintain the
Advances or any portion thereof. Any Lenders' certification of such costs and
expenses shall, absent any manifest error, be conclusive and binding on the
Borrower.

deliver to the Security Trustee, upon the Administrative Agent's request, such
additional collateral as may be satisfactory to the Lenders in their sole
discretion of sufficient value to restore compliance with the Required
Percentage or (b) the Lenders shall reduce their Commitments hereunder and the
Borrower shall, if necessary, prepay such Advances or part thereof (together
with interest thereon and any other monies payable in respect of such prepayment
pursuant to Section 5.4) as shall result in the FMV of the Units then mortgaged
to the Security Trustee being not less than the Required Percentage.

9.4 Reduction of Collateral. (a) In the event of the Total Loss of a Unit or the
sale by a Guarantor of its Unit, upon such Total Loss or prior to or
simultaneously with such sale the Credit Facility shall, on the date of the
Total Loss or sale, be reduced by $12,500,000, provided, however, that, if the
FMV of the remaining Unit then mortgaged to the Security Trustee is less than
200% of the maximum amount then available under the Credit Facility, after
giving effect to the reduction as aforesaid, the Credit Facility shall be
reduced by the amount of such shortfall divided by two (2), and, the Borrower
shall, if necessary, prepay such Advances or part thereof (together with
interest thereon and any other monies payable in respect of such prepayment
pursuant to Section 5.4) as required so that the principal amount thereof does
not exceed the reduced available Commitments.

                  (b) Unless otherwise agreed by the Lenders, any sale of a Unit
shall be for cash and shall not be subject to any contingencies.


                                       38
<PAGE>


                  (c) In the event of a sale or Total Loss of Unit as
contemplated by this Section 9.4, the Creditors agree to release the relevant
Guarantor from its obligations under the Guaranty and the Security Documents in
respect of its Unit upon the reduction of Commitment provided for in Section
9.4(a) or the substitution of a Unit as provided for in Section 9.4(b).

9.5 Inspection and Survey Reports. If the Lenders shall so request, the
Borrowers shall provide the Lenders with copies of all internally generated
inspection or survey reports on the Units.

10.       ASSIGNMENT.

                  This Agreement shall be binding upon, and inure to the benefit
of, the Borrower and the Creditors and their respective successors and assigns,
except that the Borrower may not assign any of its rights or obligations
hereunder. Each Lender shall be entitled to assign its rights and obligations
under this Agreement or grant participation(s) in the Credit Facility to any
subsidiary, holding company or other affiliate of such Lender, to any subsidiary
or other affiliate company of any thereof or, with the consent of the Borrower
and the Arrangers, not to be unreasonably withheld, to any other bank or
financial institution, and such Lender shall forthwith give notice of any such
assignment or participation to the Borrower; provided, however, that any such
assignment must be made pursuant to an Assignment and Assumption Agreement. The
Borrower will take all reasonable actions requested by the Administrative Agent
or any Lender to effect such assignment, including, without limitation, the
execution of a written consent to such Assignment and Assumption Agreement.

11.      ILLEGALITY, INCREASED COST, NON-AVAILABILITY, ETC.

11.1 Illegality. In the event that by reason of any change in any applicable
law, regulation or regulatory requirement or in the interpretation thereof, a
Lender has a reasonable basis to conclude that it has become unlawful for any
Lender to maintain or give effect to its obligations as contemplated by this
Agreement, such Lender shall inform the Administrative Agent and the Borrower to
that effect, whereafter the liability of such Lender to make its Commitment
available shall forthwith cease and the Borrower shall be required either to
repay to such Lender that portion of the Advances advanced by such Lender
immediately or, if such Lender so agrees, to repay such portion of the Advances
to the Lender on the last day of any then current Interest Period in accordance
with and subject to the provisions of Section 11.5. In any such event, but
without prejudice to the aforesaid obligations of the Borrower to repay such
portion of the Advances, the Borrower and the relevant Lender shall negotiate in
good faith with a view to agreeing on terms for making such portion of the
Advances available from another jurisdiction or


                                       39
<PAGE>


otherwise restructuring such portion of the Credit Facility on a basis which is
not unlawful.

11.2 Increased Costs. If any change in applicable law, regulation or regulatory
requirement, or in the interpretation or application thereof by any governmental
or other authority, shall:

                   (i)     subject any Lender to any Taxes with respect to its
                           income from the Credit Facility, or any part thereof,
                           or

                  (ii)     change the basis of taxation to any Lender of
                           payments of principal or interest or any other
                           payment due or to become due pursuant to this
                           Agreement (other than a change in the basis effected
                           by the jurisdiction of organization of such Lender,
                           the jurisdiction of the principal place of business
                           of such Lender, the United States of America, the
                           State or City of New York or any governmental
                           subdivision or other taxing authority having
                           jurisdiction over such Lender (unless such
                           jurisdiction is asserted by reason of the activities
                           of the Borrower or any of the other Security Parties)
                           or such other jurisdiction where the Credit Facility
                           may be payable), or

                 (iii)     impose, modify or deem applicable any reserve
                           requirements or require the making of any special
                           deposits against or in respect of any assets or
                           liabilities of, deposits with or for the account of,
                           or loans by, a Lender, or

                  (iv)     impose on any Lender any other condition affecting
                           the Credit Facility or any part thereof,

and the result of the foregoing is either to increase the cost to such Lender of
making available or maintaining its Commitment or any part thereof or to reduce
the amount of any payment received by such Lender, then and in any such case if
such increase or reduction in the opinion of such Lender materially affects the
interests of such Lender under or in connection with this Agreement:

                  (a)      the Lender shall notify the Administrative Agent and
                           the Borrower of the happening of such event, and

                  (b)      the Borrower agrees forthwith upon demand to pay to
                           such Lender such amount as such Lender certifies to
                           be necessary to compensate such Lender for such
                           additional cost or such reduction, provided,


                                       40
<PAGE>


                           however, that the foregoing provisions shall not be
                           applicable in the event that increased costs to the
                           Lender result from the exercise by the Lender of its
                           right to assign its rights or obligations under
                           Section 10.

11.3 Nonavailability of Funds. If the Administrative Agent shall determine that,
by reason of circumstances affecting the London Interbank Market generally,
adequate and reasonable means do not or will not exist for ascertaining the
Applicable Rate for any Advance for any Interest Period, the Administrative
Agent shall give notice of such determination to the Borrower. The Borrower and
the Agents shall then negotiate in good faith in order to agree upon a mutually
satisfactory interest rate and/or Interest Period to be substituted for those
which would otherwise have applied under this Agreement. If the Borrower and the
Agents are unable to agree upon such a substituted interest rate and/or Interest
Period within thirty (30) days of the giving of such determination notice, the
Agents shall set an interest rate and Interest Period to take effect from the
expiration of the Interest Period in effect at the date of determination, which
rate shall be equal to the Margin plus the cost to the Lenders (as certified by
each Lender) of funding such Advance. In the event the state of affairs referred
to in this Section 11.3 shall extend beyond the end of the Interest Period, the
foregoing procedure shall continue to apply until circumstances are such that
the Applicable Rate may be determined pursuant to Section 6.

11.4 Lender's Certificate Conclusive. A certificate or determination notice of
any Lender as to any of the matters referred to in this Section 11 shall, absent
manifest error, be conclusive and binding on the Borrower.

11.5 Compensation for Losses. Where any Advance or a portion thereof is to be
repaid by the Borrower pursuant to this Section 11, the Borrower agrees
simultaneously with such repayment to pay to the relevant Lender all accrued
interest to the date of actual payment on the amount repaid and all other sums
then payable by the Borrower to the relevant Lender pursuant to this Agreement,
together with such amounts as may be certified by the relevant Lender to be
necessary to compensate such Lender for any actual loss, premium or penalties
incurred or to be incurred thereby on account of funds borrowed to make, fund or
maintain its Commitment or such portion thereof for the remainder (if any) of
the then current Interest Period or Periods, if any, but otherwise without
penalty or premium.

12.       CURRENCY INDEMNITY

12.1 Currency Conversion. If for the purpose of obtaining or enforcing a
judgment in any court in any country it becomes necessary to convert into any
other currency (the "judgment currency") an amount due in Dollars under this
Agreement, the Note, the Guaranty or any of the Security Documents then the
conversion shall be made, in the discretion of the Administrative Agent, at the
rate of exchange prevailing either on the date of default or on the day before
the day on which the judgment is given or the order for enforcement is made, as
the case may be (the "conversion date"), provided that the Administrative Agent
shall not be entitled to recover under this section any amount in the judgment
currency which exceeds at the conversion date the amount in Dollars due under
this Agreement, the Note, the Guaranty and/or any of the Security Documents.

12.2 Change in Exchange Rate. If there is a change in the rate of exchange
prevailing between the conversion date and the date of actual payment of the
amount due, the Borrower shall pay such additional amounts (if any, but in any
event not a lesser amount) as may be necessary to ensure that the amount paid in
the judgment currency when converted at the rate of exchange prevailing on the
date of payment will produce the amount then due under this Agreement, the Note,
the Guaranty and/or any of the Security Documents in Dollars; any excess over
the amount due received or collected by the Lenders shall be remitted to the
Borrower.

12.3 Additional Debt Due. Any amount due from the Borrower under Section 12
shall be due as a separate debt and shall not be affected by judgment being
obtained for any other sums due under or in respect of this Agreement, the Note,
the Guaranty and/or any of the Security Documents.

12.4. Rate of Exchange. The term "rate of exchange" in this Section 12 means the
rate at which the Administrative Agent in accordance with its normal practices
is able on the relevant date to purchase Dollars with the judgment currency and
includes any premium and costs of exchange payable in connection with such
purchase.

13       FEES AND EXPENSES

13.1 Commitment Fee. The Borrower shall pay to the Administrative Agent on
behalf of the Lenders a fee in the amount of (i) .25% per annum on the available
but undrawn amount of the Credit Facility from the date hereof through the
initial Drawdown Date and (ii) .50% per annum thereafter, in each case quarterly
in arrears from the date hereof. Such fee shall accrue from day-to-day and be
calculated on the actual number of days elapsed and a three hundred sixty (360)
day year.


                                       42

$10,000 payable upon the signing of this Agreement and annually thereafter,
which agency fee shall be shared equally by the Agents.

13.3 Arrangement Fee. The Borrower shall pay to the Arrangers an arrangement fee
equal to .50% of the Facility, such arrangement fee to be divided evenly between
the Arrangers and payable upon signing of this Agreement.

13.4 Other Fees. The Borrower shall pay such other fees to the Agents as the
parties have agreed pursuant to the Fee Letter.

13.5 Expenses. The Borrower agrees, whether or not the transactions hereby
contemplated are consummated, on demand to pay, or reimburse the Creditors for
their payment of, the reasonable expenses of the Agents, the Security Trustee,
the Arrangers and (after the occurrence and during the continuance of an Event
of Default) the Lenders incident to said transactions (and in connection with
any supplements, amendments, waivers or consents relating thereto or incurred in
connection with the enforcement or defense of any of the Agents' (the Security
Trustee's, the Arrangers' and the Lenders' rights or remedies with respect
thereto or in the preservation of the Agents', the Security Trustee's, the
Arrangers' and the Lenders' priorities under the documentation executed and
delivered in connection therewith), including, without limitation, all
reasonable costs and expenses of preparation, negotiation, execution and
administration of this Agreement and the documents referred to herein, the
reasonable fees and disbursements of the Agent's counsel in connection
therewith, as well as the reasonable fees and expenses of any independent
appraisers, surveyors, engineers and other consultants retained by the Agents,
the Security Trustee or the Arrangers in connection with this transaction, all
reasonable costs and expenses, if any, in connection with the enforcement of
this Agreement, the Note, the Guaranty and the Security Documents and stamp and
other similar taxes, if any, incident to the execution and delivery of the
documents (including, without limitation, the Note) herein contemplated and to
hold the Agents, the Security Trustee, the Arrangers and the Lenders free and
harmless in connection with any liability arising from the nonpayment of any
such stamp or other similar taxes. Such taxes and, if any, interest and
penalties related thereto as may become payable after the date hereof shall be
paid immediately by the Borrower to the Agents, the Security Trustee, the
Arrangers or the Lenders, as the case may be, when liability therefor is no
longer contested by such party or parties or reimbursed immediately by the
Borrower to such party or parties after payment thereof (if the Agents, the
Security Trustee, the Arrangers or the Lenders, at their sole discretion,
chooses to make such payment).

WITH THIS AGREEMENT, THE NOTE, THE GUARANTY OR THE SECURITY DOCUMENTS.

15.      THE AGENTS

15.1 (a) Appointment of Agents. Each of the Lenders hereby irrevocably appoints
and authorizes each Agent (which for purposes of this Section 15 shall be deemed
to include the Security Trustee pursuant to Section 15.1(b)) to take such action
as agent on its behalf and to exercise such powers under this Agreement, the
Note, the Guaranty and the Security Documents as are delegated to such Agent by
the terms hereof and thereof. No Agent nor any of its directors, officers,
employees or agents shall be liable for any action taken or omitted to be taken
by it or them under this Agreement, the Note, the Guaranty or the Security
Documents or in connection therewith, except for its or their own gross
negligence or willful misconduct.

                  (b) Appointment of Security Trustee. Each of the Creditors
irrevocably appoints the Security Trustee as security trustee on its behalf with
regard to (i) the security, powers, rights, titles, benefits and interests (both
present and future) constituted by and conferred on the Creditors or any of them
or for the benefit thereof under or pursuant to this Agreement, the Note, the
Guaranty or any of the Security Documents (including, without limitation, the
benefit of all covenants, undertakings, representations, warranties and
obligations given, made or undertaken to any Creditor in the Agreement, the
Note, the Guaranty or any Security Document), (ii) all moneys, property and
other assets paid or transferred to or vested in any Creditor or any agent of

person and (iii) all money, investments, property and other assets at any time
representing or deriving from any of the foregoing, including all interest,
income and other sums at any time received or receivable by any Creditor or any
agent of any Creditor in respect of the same (or any part thereof). The Security
Trustee hereby accepts such appointment.

15.2 Distribution of Payments. Whenever any payment is received by the
Administrative Agent from the Borrower or any other Security Party for the
account of the Creditors, or any of them, whether of principal or interest on
the Note, commissions, fee under Section 13.1 or otherwise, it will thereafter
cause to be distributed on the same day if received before 11 a.m. New York
time, or on the next day if received thereafter, like funds relating to such
payment to the Creditors according to their respective interest therein, in each
case to be applied according to the terms of this Agreement.


                                       45
<PAGE>


15.3 Holder of Interest in Note. The Administrative Agent may treat each Lender
as the holder of all of the interest of such Lender in the Note.

15.4 No Duty to Examine, Etc. The Agents shall not be under a duty to examine or
pass upon the validity, effectiveness or genuineness of any of this Agreement,
the Guaranty, the Note, the Security Documents or any instrument, document or
communication furnished pursuant to this Agreement or in connection therewith or
in connection with the Note, the Guaranty or any Security Document, and the
Agents shall be entitled to assume that the same are valid, effective and
genuine, have been signed or sent by the proper parties and are what they
purport to be.

15.5 Agents as Lenders. With respect to that portion of the Advances made
available by it, each Agent shall have the same rights and powers hereunder as
any other Lender and may exercise the same as though it were not an Agent, and
the term "Lender" or "Lenders" shall include such Agent in its capacity as a
Lender. Each Agent and its affiliates may accept deposits from, lend money to
and generally engage in any kind of business with, the Borrower and the other
Security Parties as if it were not an Agent.

15.6 (a) Obligations of Agents. The obligations of each Agent under this
Agreement, under the Note, under the Guaranty and under the Security Documents
are only those expressly set forth herein and therein.

     (b) No Duty to Investigate. No Agent shall at any time be under any
duty to investigate whether an Event of Default, or an event which with the
giving of notice or lapse of time, or both, would constitute an Event of
Default, has occurred or to investigate the performance of this Agreement, the
Note, the Guaranty or any Security Document by any Security Party.

15.7 (a) Discretion of Agents. Each Agent shall be entitled to use its
discretion with respect to exercising or refraining from exercising any rights
which may be vested in it by, and with respect to taking or refraining from
taking any action or actions which it may be able to take under or in respect
of, this Agreement, the Note, the Guaranty and the Security Documents, unless
such Agent shall have been instructed by the Majority Lenders to exercise such
rights or to take or refrain from taking such action; provided, however, that
such Agent shall not be required to take any action which exposes such Agent to
personal liability or which is contrary to this Agreement or applicable law.

         (b) Instructions of Majority Lenders. Each Agent shall in all cases be
fully protected in acting or refraining from acting under this Agreement, under
the Note, under the Guaranty or under any Security Document in accordance with
the instructions of the Majority Lenders, and any action taken or failure to act
pursuant to such instructions shall 


                                       46
<PAGE>


be binding on all of the Lenders. Neither this Agreement nor any of the Security
Documents nor any terms hereof or thereof may be amended unless such amendment
is approved by the Borrower and the Majority Lenders, provided that no such
amendment shall, without the consent of each Lender affected hereby, (i) extend
the Credit Facility Period, or reduce the rate or extend the time of payment of
principal or interest or fees thereon, or reduce the principal amount of the
Advances, (ii) increase the Commitment of any Lender over the amount thereof
then in effect (it being understood that a waiver of any Default or Event of
Default or any mandatory repayment of Advances shall not constitute a change in
the terms of any Commitment of any Lender), (iii) amend, modify or waive any
provision of this Section 15.7, (iv) amend the definition of Majority Lenders,
(v) consent to the assignment or transfer by the Borrower of any of its rights
and obligations under this Agreement, (vi) release any Security Party from any
of its obligations under any Security Document except as expressly provided
herein or in such Security Document or (vii) amend any provision relating to the
maintenance of collateral under Section 9.3. All amendments approved by the
Majority Lenders under this Section 15.7 must be in writing and signed by the
Borrower and each of the Lenders. In the event that any Lender is unable to or
refuses to sign an amendment approved by the Majority Lenders hereunder, such
Lender hereby appoints the Administrative Agent as its Attorney-In-Fact for the
purposes of signing such amendment. No provision of this Section 15 or any other
provisions relating to the Agents may be modified without the consent of the
Agents.

15.8 Assumption re Event of Default. Except as otherwise provided in Section
15.14, the Administrative Agent shall be entitled to assume that no Event of
Default, or event which with the giving of notice or lapse of time, or both,
would constitute an Event of Default, has occurred and is continuing, unless the
Administrative Agent has been notified by any Security Party of such fact, or
has been notified by a Lender that such Lender considers that an Event of
Default or such an event (specifying in detail the nature thereof) has occurred
and is continuing. In the event that the Administrative Agent shall have been
notified by any Security Party or any Lender in the manner set forth in the
preceding sentence of any Event of Default or of an event which with the giving
of notice or lapse of time, or both, would constitute an Event of Default, the
Administrative Agent shall notify the Lenders and shall take action and assert
such rights under this Agreement, under the Note, under the Guaranty and under
Security Documents as the Majority Lenders shall request in writing.

15.9 No Liability of Agents or Lenders.  Neither the Agents nor any of the
Lenders shall be under any liability or responsibility whatsoever:

         (A) to any Security Party or any other person or entity as a
consequence of any failure or delay in performance by, or any breach by, any
other Lenders or any other


                                       47
<PAGE>


person of any of its or their obligations under this Agreement or under any
Security Document;

         (B) to any Lender or Lenders as a consequence of any failure or delay
in performance by, or any breach by, any Security Party of any of its respective
obligations under this Agreement, under the Note, under the Guaranty or under
the Security Documents; or

         (C) to any Lender or Lenders for any statements, representations or
warranties contained in this Agreement, in the Guaranty, in any Security
Document or in any document or instrument delivered in connection with the
transaction hereby contemplated; or for the validity, effectiveness,
enforceability or sufficiency of this Agreement, the Note, the Guaranty, any
Security Document or any document or instrument delivered in connection with the
transactions hereby contemplated.

15.10 Indemnification of Agents. The Lenders agree to indemnify each Agent (to
the extent not reimbursed by the the Security Parties or any thereof), pro rata
according to the respective amounts of their Commitments, from and against any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever (including legal fees and expenses incurred in investigating claims
and defending itself against such liabilities) which may be imposed on, incurred
by or asserted against, such Agent in any way relating to or arising out of this
Agreement, the Note, the Guaranty or any Security Document, any action taken or
omitted by such Agent thereunder or the preparation, administration, amendment
or enforcement of, or waiver of any provision of, this Agreement, the Note, the
Guaranty or any Security Document, except that no Lender shall be liable for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from such Agent's
gross negligence or willful misconduct.

15.11 Consultation with Counsel. Each Agent may consult with legal counsel
selected by such Agent and shall not be liable for any action taken, permitted
or omitted by it in good faith in accordance with the advice or opinion of such
counsel.

15.12 Resignation of Administrative Agent. The Administrative Agent may resign
at any time by giving sixty (60) days' written notice thereof to the Lenders and
the Borrower. Upon any such resignation, the Lenders shall have the right to
appoint a successor Administrative Agent. If no successor Administrative Agent
shall have been so appointed by the Lenders and shall have accepted such
appointment within sixty (60) days after the retiring Administrative Agent's
giving notice of resignation, then the retiring Administrative Agent may, on
behalf of the Lenders, appoint a successor 


                                       48
<PAGE>

4.   Representatives and Progress of Platform.

     (a)  Seller will furnish office space and parking facilities at the Yard
for Buyer's authorized representatives (the "Representative"), who will have
complete and unrestricted access to the Yard of Seller, or its subcontractors,
where the Platform under this Agreement is being constructed. The office
provided to Buyer will have telephone, telefax, and duplicating facilities. 
Costs for long distance telephone calls, telefaxes, and duplication will be for
Buyer's account. Such authorized Representatives shall have the right to make
inspection of workmanship, material, equipment and supplies as the construction
of the Platform progresses and shall notify Seller in writing of any
deficiencies noted therein, and Seller will then take such steps as are
necessary to correct such deficiencies. Seller shall give notice to Buyer and
its Representative at least forty-eight (48) hours in advance of the date and
place of all tests, trials, and inspections. Inspections shall be made so as not
to impede the progress of the construction of the Platform and if defective or
non-conforming workmanship or material is rejected, rejection shall be made
promptly in order that Seller may minimize the expense and disruption of
construction. In the event Buyer's Representative shall fail to be present at
any properly notified test, trial, or inspection, the results thereof shall be
binding on Buyer. Buyer shall ensure that its Representative shall not in 

                                         4

<PAGE>

performing their inspections obstruct the construction schedule for the
Platform. If Buyer's Representative fails to promptly submit to Seller
notification of any non-conforming work discovered by Buyer's Representative,
Buyer shall be deemed to have approved such item and Buyer shall be precluded
from making demand for correction of such item, refusing to accept tender of
delivery of the Platform, or claiming such item as a warranty defect under
Seller's warranty set forth in Section 11 herein below.

     (b)  In all working hours during the construction of the Platform until
delivery thereof, the Representative and all assistants of the Representative
shall be given free and ready access to the Platform and to any other place
where construction of the Platform is being done or materials are being
processed or stored in connection with the construction of the Platform,
including the yards, workshops, stores and offices of Seller, and the premises
of subcontractors of Seller who are doing work for the Platform or storing
materials at such premises in connection with the Platform's construction.

     (c)  Seller shall appoint a project manager who shall be the direct
interface with the Buyer's Representative, with full authority to act for Seller
under this Agreement.

     (d)  Any difference in opinion between parties hereto which may arise
during the construction of the Platform concerning technical matters in respect
of the materials and workmanship covered by ABS rules, such difference in
opinion shall be referred to ABS whose opinion thereof shall be final and
binding upon both parties.

     (e)  Within thirty (30) days of the date of this Agreement the Seller shall
deliver to the Buyer a key event production schedule (the "Production Schedule")
showing planned construction progress of the Platform. The Production Schedule
shall be reasonably acceptable to the Buyer. The Seller shall develop an overall
Platform erection plan that integrates material delivery and assembly actions
needed to schedule work flow during all phases of construction. This plan shall
encompass sufficient planning data to assure that all phases of construction can
be adequately accomplished so as to deliver the Platform on or before the
Scheduled Delivery Date. The Platform erection/construction plan shall be
furnished to Buyer within sixty (60) days after the effective date of this
Agreement and shall, upon acceptance by Buyer, become by reference an integral
part of the Production Schedule. The Scheduled Delivery Date shall be extended
by any delay to Seller caused by act or omission of Buyer, failure to timely
deliver to Seller any Buyer Furnished Equipment, delays caused by ABS or any
governmental agency, changes, events of force majeure, or inability of or
failure or 


                                         5

<PAGE>

refusal of LeTourneau to fully and timely perform all of its covenants,
agreements, and undertakings under the LeTourneau Agreements or if all subjects
and conditions under the LeTourneau Agreements are not fully and timely met.

     (f)  Included in the Specifications is a list of tests and trials to be
performed by Seller in connection with the completion of the Platform. Buyer's
Representative shall be given the number of days of prior notice for each
applicable test or trial as set forth in the Specifications.

5.   Changes and Additional Work.

     (a)  Buyer shall have the right, at any time or times, to request that
reasonable change or changes be made in any of the Specifications, and Buyer
shall issue to Seller a written change order to be executed by Buyer and Seller;
provided, however, if such requested change or changes in the aggregate would
materially increase the overall scope of work so as to adversely impact Seller's
other work or commitments or if LeTourneau refuses to agree to any requested
change with respect to the Package or the Equipment or if Seller and Buyer
cannot reach agreement as to a lump sum price or credit or change in the
Scheduled Delivery Date or other terms and conditions of this Agreement or the
Specifications, Seller shall have no obligation to Buyer to perform same. If any
change necessitates an increase or decrease in the quantity or quality of the
materials or the nature of the labor to be furnished by Seller for the Platform,
then the Contract Price shall be increased or decreased on a lump sum basis in
accordance with the mutual agreement of the parties. Seller shall be entitled to
make minor changes to the Specifications, if found necessary, for the
introduction of improved production methods or otherwise, subject to Buyer's
approval not to be unreasonably withheld.

     (b)  If any such change will prolong the time for completion of the
Platform, the Scheduled Delivery Date provided hereunder shall be extended
accordingly.

6.   Buyer Furnished Equipment.

     (a)  Within forty five (45) days of the execution of this Agreement, Seller
shall furnish to Buyer a schedule of in-yard delivery dates of those items of
material, equipment, engineering data and information ("Buyer Furnished
Equipment"), as are set forth in the Specifications to be provided by Buyer. The
time for delivery of the Buyer Furnished Equipment as detailed on such delivery
schedule shall be such so as to not 

                                         6
                                          
<PAGE>

cause Seller to be delayed in the timely prosecution of the work in accordance
with the Production Schedule.

     (b)  Seller shall at its own cost install the Buyer Furnished Equipment.
Seller's scope of work includes all necessary foundations and supplies, such as,
but not limited to, electric power, air, fuel, steam, etc. All Buyer Furnished
Equipment shall be delivered by Buyer to Seller at Seller's Yard in their
assembled form, tested and in proper condition, ready for installation in or on
the Platform, in accordance with the Production Schedule. Seller will assist
Buyer in unloading all Buyer Furnished Equipment. Suitable storage will be
provided by Seller for all Buyer Furnished Equipment.

     (c)  In order to facilitate installation by Seller of the Buyer Furnished
Equipment on the Platform, Buyer shall furnish the Seller with all necessary
information including specifications, plans, drawings, instruction books,
manuals, test reports and certificates. Buyer, if so requested by Seller, shall
without any charge to Seller cause representatives of the manufacturers of the
Buyer Furnished Equipment to assist Seller in installation thereof in or on the
Platform and/or to carry out installation thereof by themselves or to make
necessary adjustments thereof at the Yard. Seller's scope of work under this
Agreement excludes any testing, adjustment of equipment, repair and modification
and supply of all inter-connecting parts.

     (d)  In the event of a delay in delivery of any Buyer Furnished Equipment,
then Buyer and Seller shall mutually agree on a new installation date of the
delayed Buyer Furnished Equipment. If no agreement is reached between both
parties within fifteen (15) days, then Seller shall have the right to proceed
with the construction of the Platform without installation thereof on the
Platform, without prejudice to Seller's other rights as hereinabove provided,
and Buyer shall accept and take delivery of Platform as so constructed.

     (e)  On delivery of each consignment of Buyer Furnished Equipment, Seller
shall assist Buyer in the inspection of the consignment delivered. Any and all
of the Buyer Furnished Equipment shall be subject to Seller's reasonable right
of rejection as and if they are found to be unsatisfactory or in improper
condition for installation. In such instances, Seller shall first give adequate
notice to Buyer before being entitled to reject the Buyer Furnished Equipment.

                                         7
<PAGE>

     (f)  Should Buyer fail to timely deliver the Buyer Furnished Equipment as
provided in this Agreement and such delay results in increased costs to Seller,
Buyer shall reimburse Seller for such increased cost as and when incurred.

7.   Liens.

     Provided Seller is paid all amounts owing to Seller by Buyer under this
Agreement as and when due, Seller shall not place or create or permit to be
placed or created, any liens, charges, or encumbrances on, or security interests
as to, or pledges of, the Platform, and any lien, charge, encumbrance or
security interest so placed or created by or though Seller, its subcontractors
and suppliers, or any of them, shall be forthwith released by the Seller. The
Seller shall release and cause to be discharged any such lien, charge,
encumbrance or security interest. In the event Seller fails to secure the
discharge or release of any such lien, charge, encumbrance or security interest,
after notice to Seller the Buyer may secure the removal of same, in which event
the Seller shall reimburse the Buyer for its costs of securing such discharge or
release (which cost shall include any expenses incurred in connection therewith)
or at Buyer's sole option by deducting such sum from any payments due or to
become due the Seller's under this Agreement. In the event such cost is in
excess of the amount of any such reimbursement by deductions, the Seller further
agrees to pay the amount of such excess to the Buyer upon demand.

8.   Insurance.

     Seller shall obtain and maintain during all times hereunder the following
insurances:

     (a)  Worker's Compensation (including occupational disease), United States
Longshoremen and Harbor Workers, and employer's liability insurance in
accordance with the applicable statutory requirements of the jurisdiction in
which the Platform is constructed, with maritime and in rem, alternate employer,
and voluntary compensation coverages, with limits on the employer's liability
coverage of not less than U.S. $1,000,000 for bodily injury per person and with
excess liability limits of not less than U.S. $l,000,000 per occurrence.

     (b)  Broad Form Comprehensive General Liability Insurance covering all of
the operations of Seller, including Contractual Liability and Contractor's
Protective Liability with a combined single limit of not less than U.S.
$1,000,000 per occurrence 

                                         8
<PAGE>

for bodily injury and/or property damage, including products and completed
operations coverage, with excess liability limits of not less than U.S.
$1,000,000 per occurrence.

     (c)  Each of the foregoing insurance policies shall, either on the face
thereof or by appropriate endorsement name (except for the policies specified in
subparagraph (a) above) Buyer as an additional assured with respect to the
indemnities of Seller assumed under this Agreement, provide that the insurance
policy shall not be cancelled or coverage reduced except upon 30 days prior
written notice to Buyer, contain waivers of subrogation pursuant to which the
insurer waives all express or implied rights of subrogation against Buyer,
provide that Buyer shall not be liable for premiums or calls, and be retained in
full force and effect by Seller until the conclusion of the Platform hereunder
as provided below. Seller shall be responsible for all deductibles and self
insured retentions, to the extent the loss or claim would otherwise be covered
by Seller's indemnities contained in this Agreement. Concurrently with the
execution of this Agreement, Seller shall furnish to Buyer certificates or other
evidence satisfactory to the other of the insurance required hereunder.

     (d)  Until final delivery of the Platform, Seller shall its own cost and
expense, keep the Platform and all materials either delivered to the Yard or
being handled by Seller for the Platform or built into, or installed in or upon
the Platform fully insured under coverage and with underwriters satisfactory to
the Buyer and not more restrictive than the current form of London or American
Institute Clauses for Builder's Risks or equivalent form, including tests and
trials clauses. The Builder's Risks insurance shall include supplemental
coverage for war risks, strikes, lockouts, labor disturbances, riot or civil
commotion, earthquakes, and protection and indemnity risks. The amount of such
insurance coverage shall be in an amount at least equal to the Contract Price
and shall be increased from time to time to cover the cost of all changes,
alterations, or modifications.

     (e)  The Builders Risks policy shall be taken out in the joint names of
Seller and Buyer and all losses under such policy shall be payable to the Seller
and Buyer in accordance with their respective interests. The policies shall
provide that there shall be no recourse against the Buyer for the payment of
premiums or other charges and shall further provide that at least thirty (30)
days' prior written notice of any material alteration, cancellation, or
cancellation for the non-payment of premiums or other charges shall be given to
the Buyer by the insurance underwriters. Any deductible under this insurance
policy shall be for the account of Seller.

9.   Title and Risk of Loss.

     (a)  Title to the Platform, to the extent complete, including all materials
destined for incorporation therein, whether located at Seller's Yard or
elsewhere, shall immediately vest in Buyer when the same is paid for by Buyer,
whether prior to or after incorporation into the Platform. The vesting of title
shall not relieve Seller of its obligation to replace damaged or defective
materials at Seller's expense and to complete and deliver the Platform in
accordance with the provisions of this Agreement. Risk of loss of the Platform
shall pass to Buyer upon delivery and acceptance thereof in accordance with this
Agreement.

     (b)  If the Platform or any Buyer Furnished Equipment shall be damaged by
any insured cause whatsoever prior to acceptance thereof by Buyer and such
damage does not constitute an actual or a constructive total loss of the
Platform, Seller and/or Buyer shall apply the amount recovered under the
insurance policy referred to in Paragraph 8(d) of this Agreement to the repair
of such damage and Buyer shall accept the Platform under this Agreement if
completed in accordance with this Agreement and the Specifications. The
Production Schedule including the Scheduled Delivery Date shall be deemed
extended by the time necessary to repair such damage.

     (c)  In the event of an actual or constructive total loss of the Platform
prior to delivery, this Agreement shall automatically be deemed terminated, and
Seller shall retain all progress payments made pursuant to Paragraph 2(b)
hereinbelow and shall be paid by Buyer for the price for that portion of the
Platform then constructed for which progress payments have not yet been made and
all work in progress (including profit on all to Seller). In the event that the
actual or constructive total loss of the Platform results from the operation of
an insurable risk covered by insurance as required under Paragraph 8(d) of this
Agreement, all of the proceeds of such insurance payable as a result of such
loss shall be paid to the Buyer and the Seller as their interests may appear.

10.  Delivery.

     (a)  Upon completion of the construction of the Platform and the tests and
trials as provided in the Specifications, Seller shall tender delivery of the
Platform to Buyer. Prior to tendering delivery, Seller shall have remedied at
Seller's sole cost and expense any defects discovered by Buyer or Seller in
Seller's workmanship or materials including installation of Buyer Furnished
Equipment or any other nonconformity of the Platform with the requirements of
the Specifications and performed any retests 

                                         10

<PAGE>

necessary to ensure that such items have been fully corrected. Buyer shall
accept such tender of delivery, and Buyer shall not have the right to refuse to
accept delivery of the Platform provided the same is substantially completed and
capable of being utilized by Buyer. Any remaining items shall be completed by
Seller following delivery and prior to departure of the Platform from Seller's
Yard, or Buyer and Seller may mutually agree on an appropriate reduction of the
Contract Price for such remaining items.

     (b)  On the Delivery Date, Buyer shall pay to Seller all amounts payable
under this Agreement and Seller and Buyer shall execute and deliver a Protocol
of Acceptance and Delivery acknowledging delivery of the Platform. Seller shall
further deliver to Buyer a Bill of Sale confirming the conveyance of title to
the Platform to the Buyer, which Bill of Sale shall (i) generally describe the
Platform as a mobile, self-contained and elevating platform, (ii) contain a
general warranty of title and freedom from liens (except as to matters arising
by, through, or under Buyer) in favor of the Buyer, and (iii) be deemed to
contain the additional warranties and covenants set forth in Section 11
hereinbelow without the necessity of making any reference to such warranties in
the Bill of Sale. Seller shall also deliver to Buyer the remaining delivery
documents set forth in the Specifications.

     (c)  Seller shall deliver the Platform along side Seller's dock at the
Yard. Following delivery, Buyer shall have the right to dock the Platform at
Seller's Yard for a period not to exceed fourteen (14) days, after which time
the Platform must depart from Seller's Yard. During such post-delivery docking
period, Buyer shall pay to Seller its standard charges for shore power, potable
water, and security guard service. All such charges must be paid by Buyer to
Seller prior to departure of the Platform from Seller's Yard.

11.  Warranty.

     Seller hereby warrants to Buyer that (i) Seller's workmanship and materials
shall be free from material defects, (ii) that systems designed, supplied, and
installed by Seller will perform the functions intended by this Agreement and
the Specifications, and (iii) that the components of the Equipment manufactured
by LeTourneau shall be free from material defects in LeTourneau's workmanship
and material and shall perform in accordance with the Kit Construction Agreement
and the specifications attached thereto as Annex C in normal use and service.
The warranty set forth in the preceding sentence (hereinafter referred to as the
"Warranty") shall commence on the date of delivery of the Platform to Buyer and
expire twelve (12) months thereafter (provided, however, that if any of the
equipment of the Platform, including without limitation any cranes or 


                                         11
<PAGE>

winches, is put into service prior to said delivery, the twelve (12) months
warranty period shall begin with the commencement of such service or operation
insofar as such equipment is concerned) and shall be subject to the following
provisions:

     (a)  The Warranty shall not apply to any part of the Platform which (i) has
been misused or structurally repaired or altered by anyone other than Seller or
its duly authorized representative, or (ii) has been damaged because of it use,
or the use of any other materials or equipment, after Buyer (or any other person
or firm operating the Platform or its equipment) has knowledge of such defect.
Except for the components of the Equipment manufactured by LeTourneau as
expressly set forth and as limited herein, equipment or other components of the
Platform sold to Buyer pursuant to this Agreement but not manufactured by Seller
are not warranted to any extent, but Seller shall assign (to the extent same are
assignable by Seller) to Buyer, without recourse, any warranties furnished to
Seller by the vendors of such equipment or other components. Buyer shall seek
performance or damages under such warranties only from such parties and not from
Seller. Seller shall use reasonable efforts to secure the best available
warranties available from such vendors and shall cooperate with Buyer in any
resulting dispute Buyer may have with such vendors.

     (b)  The extent of Seller's liability for any breach of the Warranty shall
be limited to (i) repairing or replacing (whichever of the two Seller, in its
sole discretion, shall elect) any material defects in Seller's workmanship or
materials, or causing the components of the Equipment manufactured by LeTourneau
to perform in accordance with the Kit Construction Agreement and the
specifications thereto by repairing or replacing (whichever of the two Seller,
in its sole discretion, shall elect) any material defects in LeTourneau's
workmanship or materials, as the case may be, at Seller's Yard or at any other
shipyard of Seller or its affiliates (hereinafter referred to as an "AMFELS
Yard"), with the Platform to be brought to an AMFELS Yard at Buyer's sole risk
and expense, or (ii) reimbursing Buyer for the cost of such repair or
replacement in accordance with the provisions of subparagraph (c) hereinbelow.

     (c)  Buyer, at its discretion, may elect to cause the necessary repairs or
replacements to be made at a non-AMFELS Yard. In such event, Seller's sole
obligation shall be to reimburse Buyer for the cost of such repairs or
replacements, provided, however, that in no event shall the sum to be paid to
Buyer by Seller exceed the cost that Seller would have borne, based on Seller's
normal rates, if the repairs or replacements had been made at the Seller's Yard.
If Buyer elects to proceed under the provisions of this subparagraph (c), Buyer
shall, as soon as possible after such election (but in any event prior to the
commencement of such repairs or replacements), notify 

                                         12
<PAGE>

Seller of the time, place, and estimated cost of such repairs and replacements.
Seller shall have the right to verify, at its sole cost and expense, by its own
representative, the nature and extent of the defects complained of prior to the
time that the repairs or replacements are made, and if in fact no breach of the
warranty made by Seller herein has occurred, Buyer shall pay to Seller a per
diem fee equal to Sellers then current labor rate schedule and the reasonable
expenses incurred by such representative.

     (d)  The REMEDIES provided in subparagraphs (b) and (c) hereinabove are
EXCLUSIVE. Buyer further agrees that in no event will Seller's liability to
Buyer for breach of the Warranty set forth in subparagraph (a) with respect to
the components of the Equipment manufactured by LeTourneau exceed such amount as
Seller may actually recover from LeTourneau for the same breach of warranty
under the Kit Construction Agreement. Such Warranty shall not include
transportation, towage, insurance, or other incidental expenses. In no event
shall the obligation of Seller to repair or replace (or to reimburse Buyer
pursuant to subparagraph (c) hereinabove for the cost of repairing or replacing)
defective workmanship or materials be construed to require Seller to repair or
replace more than the actual workmanship or material that is found to be
defective. The Platform as a whole or any other part thereof shall not be
construed to be "workmanship" or "material" for the purposes of the preceding
sentence and this Agreement.

     (e)  The Warranty shall not be effective unless Seller receives from Buyer
a written claim therefor (i) within thirty (30) days after the date of discovery
of such defect and (ii) prior to the expiration of the prescribed Warranty
period.

     (f)  Any work performed or materials furnished by Seller pursuant to the
Warranty shall be warranted for the remaining term of the original Warranty, and
nothing in subparagraph (b) or (c) shall extend the Warranty period beyond the
Warranty period specified in this Section 10.

     (g)  THE WARRANTY AS DEFINED HEREINABOVE IS IN LIEU OF ALL OTHER WARRANTIES
(EXCEPT OF TITLE), EXPRESS OR IMPLIED, STATUTORY OR AT COMMON LAW, AND ALL OTHER
LIABILITIES (AT COMMON LAW OR IN CONTRACT, TORT, OR OTHERWISE, RELATING IN ANY
WAY TO THE PLATFORM OR COMPONENTS THEREOF OR SERVICES TO BE PROVIDED UNDER THIS
AGREEMENT INCLUDING, WITHOUT LIMITATION, STRICT LIABILITY AND NEGLIGENCE).
WITHOUT LIMITATION OF THE GENERALITY OF THE IMMEDIATELY PRECEDING SENTENCE,
SELLER EXPRESSLY DISCLAIMS AND NEGATES (i) ANY 

                                         13
<PAGE>

IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY, (ii) ANY IMPLIED OR EXPRESS
WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE, (iii) ANY IMPLIED OR EXPRESS
WARRANTY OF CONFORMITY TO MODELS OR SAMPLES (iv) ANY IMPLIED OR EXPRESS WARRANTY
OF DILIGENCE, (v) ANY IMPLIED OR EXPRESS WARRANTY OF WORKMANLIKE SERVICE, (vi)
ANY IMPLIED OR EXPRESS WARRANTY OF SEAWORTHINESS, AND (vii) ALL OTHER LIABILITY,
AT COMMON LAW OR IN CONTRACT OR TORT OR OTHERWISE, INCLUDING, WITHOUT
LIMITATION, STRICT LIABILITY (WHETHER FOUNDED IN SECTION 402(A) OF THE
RESTATEMENT OF TORTS OR OTHERWISE) AND NEGLIGENCE, WHETHER OCCASIONED BY ACTS OR
OMISSIONS OF SOLE OR CONCURRENT NEGLIGENCE OF SELLER, ITS AFFILIATES AND/OR
OTHERS. SELLER DISCLAIMS LIABILITY FOR, AND IN NO EVENT WHATEVER SHALL BE LIABLE
FOR, ANY LOSS OF PROFITS OF BUYER OR OTHERS OR ANY OTHER INCIDENTAL,
CONSEQUENTIAL, PUNITIVE OR SPECIAL DAMAGES.

     (h)  Seller's liability with respect to the Buyer Furnished Equipment shall
extend only to installation thereof in accordance with the certified equipment
drawings furnished by Buyer in those instances where such Equipment is actually
installed by Seller. In all other instances (including, without limitation,
those instances in which Buyer does not furnish certified equipment drawings to
Seller), the sole risk and responsibility for the proper installation of the
Buyer Furnished Equipment shall, as between Seller and Buyer, be borne by Buyer.
In all instances the sole risk and responsibility for the operability of the
Buyer Furnished Equipment shall, as between Seller and Buyer, be borne by Buyer.

     (i)  No employee or representative of Seller is authorized to change the
Warranty in any way or to grant any other warranty.

     (j)  Buyer understands and agrees that any modification to the design of
the Package or modification to the Equipment made by the Buyer are the
responsibility of Buyer and not the responsibility of Seller for any purpose
whatsoever, including claims for damages or other liability asserted by Buyer,
its customers or any third party. In the event such modifications require
regulatory approval, Buyer shall be responsible for obtaining such approval
unless Seller accepts the responsibility by executing a change order to perform
the work as additional work under this Agreement.

     (k)  Buyer understands and agrees that the information contained in the
Package and relating to the Equipment do not guarantee a fixed or variable
weight of 

                                         14
<PAGE>

the Platform or designate the use of equipment other than the Equipment. The
fixed and variable weight of the Platform and the selection of equipment other
than the Equipment are decisions of the Buyer, including outfitting and
fabrication decisions. The weight information provided by Seller is for
information only and reflects historical information or estimated and
approximate data. Seller is unable to predict actual weights for the Platform to
be constructed by Seller. Seller does not warrant or represent that Seller's
sale or construction of a Platform will meet the historical or approximate data
supplied to Buyer.

     (l)  Buyer acknowledges that certain information to be provided by
LeTourneau relate to a LeTourneau 116-C Class Platform rather than to an
Enhanced 116-C Platform. (See Annex C to the Kit Construction Agreement). Such
supplemental information shall be deemed to be part of the Package for all
purposes of this Agreement, including the provisions of the Confidentiality
Agreement referred to in Section 29 hereinbelow. Such supplemental information
is to be provided to Seller by LeTourneau approximately 120 days after the
Effective Date of the Kit Construction Agreement. During the term of this
Agreement, LeTourneau may provide other supplemental information to Seller
relating to an Enhanced 116-C which shall, at such time, become part of the
Package for purposes of this Agreement.

          (ii) Buyer shall give Seller prompt written notice of any such claim

components purchased by Seller, Seller shall assign (to the extent same is
assignable) to Buyer, without recourse, any patent indemnity coverage granted to

15.  Force Majeure.

     For purposes of this Agreement, events of "force majeure" shall be defined
to mean all causes beyond the reasonable control of the party asserting the
benefit of this Article, and shall include but not be limited to fire,
explosion, breakdown of machinery or equipment, shortage or unavailability of
materials or equipment, delay in transportation, government order, edict, or
other action, storms, abnormal weather that prevents blasting or painting,
strikes or other labor disturbances, destruction or damage to Seller's Yard or
equipment or any Buyer Furnished Equipment or the Platform or any part thereof
from any cause; acts of Buyer or the classification society or regulatory bodies
having or proporting to have jurisdiction including failure to give timely
approvals; late delivery of Buyer Furnished Equipment or failure to furnish in a
timely manner necessary information concerning the Buyer Furnished Equipment or
the performance of the work; and any other causes or accidents of the same or
similar nature which are beyond the control of the Seller or Buyer or any or
their respective subcontractors or suppliers. In case either party shall be
unable, wholly or in part, because of any such event of force majeure to carry
out its obligations under this Agreement, the time for performance, other than
the obligation to make payments, shall be extended by the period of such actual
delay due to force majeure for which notices are given as provided hereinbelow.
Performance of any obligations suspended while any force majeure is operative
shall be resumed as soon as possible after such force majeure is operative shall
be resumed as soon as possible after such force majeure ceases. The party
seeking benefit of this paragraph shall notify the other of the occurrence of
each event of force majeure within seven (7) days after commencement of such
event. Any increased costs to Seller as the result of events of force majeure
will be compensated to Seller by Buyer. After ninety (90) continuous days of
delay in the construction of the Platform due to force majeure, Seller and Buyer
shall each have the right to terminate this Agreement without further liability
of either party to the other except that Seller shall retain all progress
payments pursuant to Paragraph 2(b) hereinabove and shall be paid by Buyer for
the price for that portion of the Platform then constructed for which progress
payments have not yet been made and all work in process (including profit on all
to Seller).

where the Platform under this Agreement is being constructed. The office

both parties.

     (e)  Within thirty (30) days of the date of this Agreement the Seller shall
deliver to the Buyer a key event production schedule (the "Production Schedule")
showing planned construction progress of the Platform. The Production Schedule

Platform erection plan that integrates material delivery and assembly actions
needed to schedule work flow during all phases of construction. This plan shall
encompass sufficient planning data to assure that all phases of construction can
be adequately accomplished so as to deliver the Platform on or before the
Scheduled Delivery Date. The Platform erection/construction plan shall be
furnished to Buyer within sixty (60) days after the effective date of this
Agreement and shall, upon acceptance by Buyer, become by reference an integral
part of the Production Schedule. The Scheduled Delivery Date shall be extended
by any delay caused by act or omission of Buyer, failure to timely deliver to
Seller any Buyer Furnished Equipment, delays caused by ABS or any governmental
agency, changes, events of force major, or inability of or failure or refusal of
LeTourneau to fully and timely perform all of its covenants, agreements, and
undertakings under the LeTourneau Agreements or if all subjects and conditions
under the LeTourneau Agreements are not fully and timely met.

     (f)  Included in the Specifications is a list of tests and trials to be
performed by Seller in connection with the completion of the Platform. Buyer's
Representative shall be given the number of days of prior notice for each
applicable test or trial as set forth in the Specifications.

5.   Changes and Additional Work.

     (a)  Buyer shall have the right, at any time or times, to request that
reasonable change or changes be made in any of the Specifications, and Buyer
shall issue to Seller a written change order to be executed by Buyer and Seller;
provided, however, if such requested change or changes in the aggregate would
materially increase the overall scope of work so as to adversely impact Seller's
other work or commitments or if LeTourneau refuses to agree to any requested
change with respect to the Package or the Equipment or if Seller and Buyer
cannot reach agreement as to a lump sum price or credit or change in the
Scheduled Delivery Date or other terms and conditions of this Agreement or the
Specifications, Seller shall have no obligation to Buyer to perform same. If any
change necessitates an increase or decrease in the quantity or quality of the
materials or the nature of the labor to be furnished by Seller for the Platform,
then the Contract Price shall be increased or decreased on a lump sum basis in
accordance with the mutual agreement of the parties. Seller shall be entitled to
make minor changes to the Specifications, if found necessary, for the
introduction of improved production methods or otherwise, subject to Buyer's
approval not to be unreasonably withheld.
     
     (b)  If any such change will prolong the time for completion of the
Platform, the Scheduled Delivery Date provided hereunder shall be extended
accordingly.

     (c)  Seller and Buyer recognize that the Contract Price set forth
hereinabove is based upon the scope of work for the platform designated as
Seller's Yard No. P178 and that the license agreement from LeTourneau is
specifically limited to the LeTourneau Super 116 design. Accordingly, the
parties agree that the Platform will be built as a Super 116 and that the
Specifications will be amended and changed to accommodate same at such time as
LeTourneau supplies the drawings and other information for the Super 116 design
and that this change will be reflected as Change Order No. 2. If this mandatory
change necessitates an increase or decrease in the quantity or quality of the
materials or the nature of the labor to be furnished by Seller for the Platform,
then the Contract Price shall be increased on a lump sum basis in accordance
with the mutual agreement of the parties. Seller will provide Buyer with
Seller's estimate of the change in the Contract Price within forty five (45)
days of receipt of all information and drawings from LeTourneau related to
Change Order No. 2. Buyer will within thirty (30) days thereafter advise Seller
in writing whether Buyer accepts or rejects such change in the Contract Price
and if rejected then Buyer's notice of rejection shall include Buyer's estimate
of the change in the Contract Price. In the event of rejection by Buyer, the
parties shall negotiate in good faith in an effort to reach resolution of the
dispute. In the event the parties, despite good faith negotiations, are unable
to agree to the lump sum price for this change, then Seller shall be entitled to
equitable and reasonable compensation (including profit) for performing same and
the amount of this compensation shall be determined by final and binding
arbitration utilizing in accordance with the Construction Industry Rules of the
American Arbitration Association. The arbitration shall be held in Houston,
Texas. Each of the parties shall nominate their own party arbitrator and the two
party arbitrators shall select the third arbitrator. In the event the party
arbitrators shall be unable to agree to the third arbitrator within ten (10)
days, the third arbitrator shall be appointed by the American Arbitration
Association. All arbitrators shall be commercial persons (and not attorneys)
with at least ten (10) years experience in the construction of mobile offshore
jackupdrilling rigs. The third arbitrator shall have no prior or current
business relationship to either party or their counsel of record. The decision
of the majority of the arbitrators shall be final, binding and enforceable in
any court of competent jurisdiction and the Parties agree that there shall be no
appeal from the arbitrators' decision. The arbitrators shall render their
decision within ninety (90) days after selection of the third arbitrator, but in
any event prior to delivery of the Platform.. The arbitrators must select either
Seller's or Buyer's price and shall have no authority to determine any other
figure for compensation to Seller for this mandatory change.

Platform and/or to carry out installation thereof by themselves or to make
necessary adjustments thereof at the Yard. Seller's scope of work under this
Agreement excludes any testing, adjustment of equipment, repair and modification
and supply of all inter-connecting parts.

     (d)  In the event of a delay in delivery of any Buyer Furnished Equipment,
then Buyer and Seller shall mutually agree on a new installation date of the

parties within fifteen (15) days, then Seller shall have the right to proceed
with the construction of the Platform without installation of the delayed Buyer
Furnished Equipment on the Platform, without prejudice to Seller's other rights
as hereinabove provided, and Buyer shall accept and take delivery of Platform as
so constructed.

     (e)  On delivery of each consignment of Buyer Furnished Equipment, Seller

provided in this Agreement and such delay results in increased costs to Seller,
Buyer shall reimburse Seller for such increased cost as and when incurred.

damage does not constitute an actual or a constructive total loss of the
Platform, Seller and/or Buyer shall apply the amount recovered under the
insurance policy referred to in Paragraph 8(d) of this Agreement to the repair
of such damage and Buyer shall accept the Platform under this Agreement if
completed in accordance with this Agreement and the Specifications.  The
Production Schedule including the Scheduled Delivery Date shall be deemed
extended by the time necessary to repair such damage.

     (d)  In the event of an actual or constructive total loss of the Platform
prior to delivery, this Agreement shall automatically be deemed terminated, and
Seller shall retain all progress payments made pursuant to Paragraph 2(b)
hereinbelow and shall be paid by Buyer for the price for that portion of the
Platform then constructed for which progress payments have not yet been made and
all work in progress (including profit on all to Seller). In the event that the
actual or constructive total loss of the Platform results from the operation of
an insurable risk covered by insurance as required under Paragraph 8(d) of this
Agreement, all of the proceeds of such insurance payable as a result of such
loss shall be paid to the Buyer and the Seller as their interests may appear.

10.  Delivery.

     (a)  Upon completion of the construction of the Platform and the tests and
trials as provided in the Specifications, Seller shall tender delivery of the
Platform to Buyer.  Prior to tendering delivery, Seller shall have remedied at
Seller's sole cost and expense any defects discovered by Buyer or Seller in
Seller's workmanship or materials including installation of Buyer Furnished
Equipment or any other nonconformity of the Platform with the requirements of
the Specifications and performed any retests necessary to ensure that such items
have been fully corrected. Buyer shall accept such tender of delivery, and Buyer
shall not have the right to refuse to accept delivery of the Platform provided
the same is substantially completed and 

                                          10

<PAGE>

capable of being utilized by Buyer. Any remaining items shall be completed by
Seller following delivery and prior to departure of the Platform from Seller's
Yard, or Buyer and Seller may mutually agree on an appropriate reduction of the
Contract Price for such remaining items.

     (b)  On the Delivery Date, Buyer shall pay to Seller all amounts payable
under this Agreement and Seller and Buyer shall execute and deliver a Protocol
of Acceptance and Delivery acknowledging delivery of the Platform. Seller shall
further deliver to Buyer a Bill of Sale confirming the conveyance of title to
the Platform to the Buyer. which Bill of Sale shall (i) generally describe the
Platform as a mobile, self-contained and elevating platform, (ii) contain a
general warranty of title and freedom from liens (except as to matters arising
by, through, or under Buyer) in favor of the Buyer, and (iii) be deemed to
contain the additional warranties and covenants set forth in Section 11
hereinbelow without the necessity of making any reference to such warranties in
the Bill of Sale. Seller shall also deliver to Buyer the remaining delivery
documents set forth in the Specifications.

     (c)  Seller shall deliver the Platform along side Seller's dock at the
Yard. Following delivery, Buyer shall have the right to dock the Platform at
Seller's Yard for a period not to exceed fourteen (14) days, after which time
the Platform must depart from Seller's Yard. During such post-delivery docking
period, Buyer shall pay to Seller its standard charges for shore power, potable
water, and security guard service. All such charges must be paid by Buyer to
Seller prior to departure of the Platform from Seller's Yard.

11.  Warranty.

     Seller hereby warrants to Buyer that (i) Seller's workmanship and materials
shall be free from material defects, (ii) that systems designed, supplied, and
installed by Seller will perform the functions intended by this Agreement and
the Specifications, and (iii) that the components of the Equipment manufactured
by LeTourneau shall be free from material defects in LeTourneau's workmanship
and material and shall perform in accordance with the Kit Construction Agreement
and the specifications attached thereto as Annex C in normal use and service.
The warranty set forth in the preceding sentence (hereinafter referred to as the
"Warranty") shall commence on the date of delivery of the Platform to Buyer and
expire twelve (12) months thereafter (provided, however, that if any of the
equipment of the Platform, including without limitation any cranes or winches,
is put into service prior to said delivery, the twelve (12) months warranty
period shall begin with the commencement of such service or operation insofar as
such equipment is concerned) and shall be subject to the following provisions:

     (a)  The Warranty shall not apply to any part of the Platform which (i) has
been misused or structurally repaired or altered by anyone other than Seller or
its duly authorized representative, or (ii) has been damaged because of it use,
or the use of any other materials or 

                                          11

<PAGE>

equipment, after Buyer (or any other person or firm operating the Platform or
its equipment) has knowledge of such defect. Except for the components of the
Equipment manufactured by LeTourneau as expressly set forth and as limited
herein, equipment or other components of the Platform sold to Buyer pursuant to
this Agreement but not manufactured by Seller are not warranted to any extent,
but Seller shall assign (to the extent same are assignable by Seller) to Buyer,
without recourse, any warranties furnished to Seller by the vendors of such
equipment or other components. Buyer shall seek performance or damages under
such warranties only from such parties and not from Seller. Seller shall use
reasonable efforts to secure the best available warranties available from such
vendors and shall cooperate with Buyer in any resulting dispute Buyer may have
with such vendors.

     (b)  The extent of Seller's liability for any breach of the Warranty shall
be limited to (i) repairing or replacing (whichever of the two Seller, in its
sole discretion, shall elect) any material defects in Seller's workmanship or
materials, or causing the components of the Equipment manufactured by LeTourneau
to perform in accordance with the Kit Construction Agreement and the
specifications thereto by repairing or replacing (whichever of the two Seller,
in its sole discretion, shall elect) any material defects in LeTourneau's
workmanship or materials, as the case may be, at Seller's Yard or at any other
shipyard of Seller or its affiliates (hereinafter referred to as an "AMFELS
Yard"), with the Platform to be brought to an AMFELS Yard at Buyer's sole risk
and expense, or (ii)reimbursing Buyer for the cost of such repair or replacement
in accordance with the provisions of subparagraph (c) hereinbelow.

     (c)  Buyer, at its discretion, may elect to cause the necessary repairs 
or replacements to be made at a non-AMFELS Yard. In such event, Seller's sole 
obligation shall be to reimburse Buyer for the cost of such repairs or 
replacements, provided, however, that in no event shall the sum to be paid to 
Buyer by Seller exceed the cost that Seller would have borne, based on 
Seller's normal rates, if the repairs or replacements had been made at the 
Seller's Yard. If Buyer elects to proceed under the provisions of this 
subparagraph (c), Buyer shall, as soon as possible after such election (but 
in any event prior to the commencement of such repairs or replacements), 
notify Seller of the time, place, and estimated cost of such repairs and 
replacements. Seller shall have the right to verify, at its sole cost and 
expense, by its own representative, the nature and extent of the defects 
complained of prior to the time that the repairs or replacements are made, 
and if in fact no breach of the Warranty made by Seller herein has occurred, 
Buyer shall pay to Seller a per diem fee equal to Sellers then current labor 
rate schedule and the reasonable expenses incurred by such representative.

     (d)  The REMEDIES provided in subparagraphs (b)and (c) hereinabove are
EXCLUSIVE. Buyer further agrees that in no event will Seller's liability to
Buyer for breach of the Warranty set forth in subparagraph (a) with respect to
the components of the Equipment manufactured by LeTourneau exceed such amount as
Seller may actually recover from 

                                          12

<PAGE>

LeTourneau for the same breach of warranty under the Kit Construction Agreement.
Such Warranty shall not include transportation, towage, insurance, or other
incidental expenses. In no event shall the obligation of Seller to repair or
replace (or to reimburse Buyer pursuant to subparagraph (c) hereinabove for the
cost of repairing or replacing defective workmanship or materials be construed
to require Seller to repair or replace more than the actual workmanship or
material that is found to be defective. The Platform as a whole or any other
part thereof shall not be construed to be workmanship or material for the
purposes of the preceding sentence and this Agreement.

     (e)  The Warranty shall not be effective unless Seller receives from Buyer
a written claim therefor (i) within thirty (30) days after the date of discovery
of such defect and (ii) prior to the expiration of the prescribed Warranty
period.

     (f)  Any work performed or materials furnished by Seller pursuant to the
Warranty shall be warranted for the remaining term of the original Warranty, and
nothing in subparagraph (b) or (c) shall extend the Warranty period beyond the
Warranty period specified in this Section 11.

     (g)  THE WARRANTY AS DEFINED HEREINABOVE IS IN LIEU OF ALL OTHER WARRANTIES
(EXCEPT OF TITLE), EXPRESS OR IMPLIED, STATUTORY OR AT COMMON LAW, AND ALL OTHER
LIABILITIES (AT COMMON LAW OR IN CONTRACT, TORT, OR OTHERWISE, RELATING IN ANY
WAY TO THE PLATFORM OR COMPONENTS THEREOF OR SERVICES TO BE PROVIDED UNDER THIS
AGREEMENT INCLUDING, WITHOUT LIMITATION, STRICT LIABILITY AND NEGLIGENCE).
WITHOUT LIMITATION OF THE GENERALITY OF THE IMMEDIATELY PRECEDING SENTENCE,
SELLER EXPRESSLY DISCLAIMS AND NEGATES (i) ANY IMPLIED OR EXPRESS WARRANTY OF
MERCHANTABILITY, (ii) ANY IMPLIED OR EXPRESS WARRANTY OF FITNESS FOR A
PARTICULAR PURPOSE, (iii) ANY IMPLIED OR EXPRESS WARRANTY OF CONFORMITY TO
MODELS OR SAMPLES (iv) ANY IMPLIED OR EXPRESS WARRANTY OF DILIGENCE, (v) ANY
IMPLIED OR EXPRESS WARRANTY OF WORKMANLIKE SERVICE, (vi) ANY IMPLIED OR EXPRESS
WARRANTY OF SEAWORTHINESS, AND (vii) ALL OTHER LIABILITY, AT COMMON LAW OR IN
CONTRACT OR TORT OR OTHERWISE, INCLUDING, WITHOUT LIMITATION, STRICT LIABILITY
(WHETHER FOUNDED IN SECTION 402(A) OF THE RESTATEMENT OF TORTS OR OTHERWISE) AND
NEGLIGENCE, WHETHER OCCASIONED BY ACTS OR OMISSIONS OF SOLE OR CONCURRENT
NEGLIGENCE OF SELLER, ITS AFFILIATES AND/OR OTHERS. SELLER DISCLAIMS LIABILITY
FOR, AND IN NO EVENT WHATEVER SHALL BE LIABLE FOR, ANY LOSS OF PROFITS OF BUYER
OR OTHERS OR ANY OTHER INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR SPECIAL DAMAGES.

                                          13

     (h)  Seller's liability with respect to the Buyer Furnished Equipment shall
extend only to installation thereof in accordance with the certified equipment
drawings furnished by Buyer in those instances where such Equipment is actually
installed by Seller. In all other instances (including, without limitation,
those instances in which Buyer does not furnish certified equipment drawings to
Seller), the sole risk and responsibility for the proper installation of the
Buyer Furnished Equipment shall, as between Seller and Buyer, be borne by Buyer.
In all instances the sole risk and responsibility for the operability of the
Buyer Furnished Equipment shall, as between Seller and Buyer, be borne by Buyer.

     (i)  No employee or representative of Seller is authorized to change the
Warranty in any way or to grant any other warranty.

     (j)  Buyer understands and agrees that any modification to the design of 
the Package or modification to the Equipment made by the Buyer are the 
responsibility of Buyer and not the responsibility of Seller for any purpose 
whatsoever, including claims for damages or other liability asserted by 
Buyer, its customers or any third party. In the event such modifications 
require regulatory approval, Buyer shall be responsible for obtaining such 
approval unless Seller accepts the responsibility by executing a change order 
to perform the work as additional work under this Agreement.

     (k)  Buyer understands and agrees that the information contained in the
Package and relating to the Equipment do not guarantee a fixed or variable
weight of the Platform or designate the use of equipment other than the
Equipment. The fixed and variable weight of the Platform and the selection of
equipment other than the Equipment are decisions of the Buyer, including
outfitting and fabrication decisions. The weight information provided by Seller
is for information only and reflects historical information or estimated and
approximate data. Seller is unable to predict actual weights for the Platform to
be constructed by Seller. Seller does not warrant or represent that Seller's
sale or construction of a Platform will meet the historical or approximate data
supplied to Buyer.

     (l)  Buyer acknowledges that certain information to be provided by
LeTourneau relate to a LeTourneau 116-C Class Platform rather than to a Super
116 Platform. (See Annex C to the Kit Construction Agreement). Since the
Platform is to be built as a Cypre Platform pursuant to Article 5, LeTourneau
shall supply supplemental information relating to Super 116 designs to Seller
which shall be deemed to be part of the Package for all purposes of this
Agreement, including the provisions of the Confidentiality Agreement referred to
in Section 29 hereinbelow. During the term of this Agreement, LeTourneau may
provide other supplemental information to Seller relating to a Super 116 which
shall, at such time, become part of the Package for purposes of this Agreement.

13.  Patent Indemnity.

     (a)  Seller hereby agrees to defend any claim or suit and to indemnify and
save  Buyer harmless from and against any damages (including the costs of the
suit and reasonable attorney's fees) awarded against Buyer in a suit arising out
of any infringement of any U.S. patent by reason of the incorporation into the
Platform in accordance with the Package of any Equipment components manufactured
by LeTourneau; provided, however, that

     (i)the indemnity contained in this Section 13 shall not apply to any claim
or suit arising out of the construction or use of (1 ) processes, devices,
apparatus, or equipment specified or furnished by Buyer or anyone else other
than Seller, for which Buyer shall indemnify and defend Seller, and mounted upon
or used in connection with the Platform; and (2) any combination of and falling
within subparagraph (i)(1) herewith of the Equipment or the Platform; and

     (ii) Buyer shall give Seller prompt written notice of any such claim or
suit and shall permit Seller to control settlement negotiations and any
litigation in connection therewith; provided, however, no settlement which
purports to acknowledge, on Buyer's behalf the validity of the patent involved
shall be entered into by Seller without Buyer's consent. As to any Equipment
components purchased by Seller, Seller shall assign (to the extent same is
assignable) to Buyer, without recourse, any patent indemnity coverage granted to
Seller by any vendor thereof Buyer shall seek performance of damages under such
warranties and Patent indemnities only from such parties and not from Seller.

     (b)  Seller makes no representations and extends no warranties that the
manufacture, construction, or commercialization of the Platform will not
infringe the claims of any United States or foreign Letters Patent that are not
included in Article II of the License Agreement, and Seller specifically
excludes any responsibility, liability, or obligation to defend Buyer or to hold
harmless and indemnify Buyer against charges, claims, or suits brought against
Buyer, its affiliates (an "affiliate" of Buyer being an entity which, directly
or indirectly, through one or more intermediaries, controls, is controlled by,
or is under common control with Buyer), assigns, successors, agents, employees,
representatives, subcontractors, or independent contractors for infringement of
any United States or foreign Letters Patent not included in Article II of the
License Agreement. Buyer further agrees that in no event shall Seller's
liability to indemnify and hold harmless Buyer as provided herein exceed such
amount as Seller may actually recover from LeTourneau for the same obligation to
indemnify and hold harmless under the License Agreement.

     (c)  Buyer agrees to defend any claim, suit, or proceeding brought against
Seller alleging that the construction or use by Seller, pursuant to this
Agreement, of any process, method of construction, construction equipment,
device, or apparatus (including, without 

                                          17

<PAGE>

limitation; Buyer Furnished Equipment) specified or furnished by Buyer or
mounted upon or used in connection with the Platform constitutes infringement of
any letters patent, and Buyer agrees to indemnify and save Seller harmless from
and against any judgment rendered against Seller as a result of such claim,
suit, or proceeding. Seller shall promptly notify Buyer in writing of any such
claim, suit, or proceeding and shall permit Buyer to control the conduct and
settlement of such claim, suit, or proceeding, provided, however, no settlement
shall be entered into without Seller's consent which purports to acknowledge on
Seller's behalf the validity of any patent. Seller shall provide information and
assistance to Buyer, at Seller's expense, as may be reasonably necessary to aid
in the conduct and settlement of the claim, suit, or proceeding. Seller shall be

THE LETOURNEAU AGREEMENTS, BREACH OF ANY WARRANTY, THE DESIGN OF THE PLATFORM OR
ANY PART THEREOF OR, OR THE LOSS OF OR LOSS OF USE OF THE PLATFORM OR ANY PART
THEREOF OR ANY OTHER EQUIPMENT, MATERIALS, OR PROPERTY), REGARDLESS OF CAUSE AND
REGARDLESS OF WHETHER SELLER, LETOURNEAU OR THEIR AFFILIATES, AND/OR THEIR
RESPECTIVE OFFICERS, EMPLOYEES, AGENTS, REPRESENTATIVES, SUBCONTRACTORS, AND/OR
OTHERS MAY BE WHOLLY, PARTIALLY, OR SOLELY NEGLIGENT OR OTHERWISE AT FAULT,

15.  Force Majeure.

     For purposes of this Agreement, events of "force majeure" shall be defined
to mean all causes beyond the reasonable control of the party asserting the
benefit of this Article, and shall include but not be limited to fire,
explosion, breakdown of machinery or equipment, shortage or unavailability of
materials or equipment, delay in transportation, government edict, or other
action, storms, abnormal weather that prevents blasting or painting, strikes or
other labor disturbances, destruction or damage to Seller's Yard or equipment or
any Buyer Furnished Equipment or the Platform or any part thereof from any
cause; acts of Buyer or the classification society or regulatory bodies having
or proporting to have jurisdiction including failure to give timely approvals;
late delivery of Buyer Furnished Equipment or failure to furnish in a timely
manner necessary information concerning the Buyer Furnished Equipment or the
performance of the work; and any other causes or accidents of the same or
similar nature which are beyond the control of the Seller or Buyer or any or
their respective subcontractors or suppliers.  In case either party shall be
unable, wholly or in part, because of any such event of force majeure to carry
out its obligations under this Agreement, the time for performance, other than
the obligation to make payments, shall be extended by the period of such actual
delay due to force majeure for which notices are given as provided hereinbelow.
Performance of any obligations suspended while any force majeure is operative
shall be resumed as soon as possible after such force majeure is operative shall
be resumed as soon as possible after such force majeure ceases. The party
seeking benefit of this paragraph shall notify the other of the occurrence of
each event of force majeure within seven (7) days after commencement of such
event. Any increased costs to Seller as the result of events of force majeure
will be compensated to Seller by Buyer. After ninety (90) continuous days of

shall each have the right to terminate this Agreement without further liability
of either party to the other except that Seller shall retain all progress

independent contractor with full power and authority to select the means,
methods and manner of performing its work hereunder.

independent contractor and not in the name of, or as an agent for, Buyer. In the
event Seller shall sublet or subcontract any of the construction of the Platform
provided for herein, Seller nevertheless shall remain primarily responsible for
compliance with all of the provisions hereof and for the portion of the
construction of the Platform performed by the party to whom the work is sublet

     Notwithstanding anything in this Agreement to the contrary, it is expressly
understood that the obligations of Seller hereunder are subject to and

28.  Severability.

     This Agreement shall cease and terminate if for any reason any of the terms
and conditions of Sections 11(9) and 14 of this Agreement (hereinafter
collectively referred to as the "Limitation of Liability Clauses") are held by
any court of competent jurisdiction to contravene or to be invalid under the
laws of any political body having jurisdiction over the subject matter hereof or
thereof; provided, however, that notwithstanding the termination of this
Agreement, Seller shall retain all progress payments then made and Buyer shall
be obligated to pay to Seller the price for that portion of the Platform then
constructed for which progress payments have not yet been made and all work in
process (including profit on all to Seller) on or before such termination. Buyer
and Seller agree not to take any action either on their own behalf, or by way of
providing assistance to or cooperating with any third party for the purpose of
invalidating any of the Limitations of Liability Clauses. If any of the terms
and conditions of this Agreement other than the terms and conditions referred to
in this Section 28 are held by any court of competent jurisdiction to contravene
or to be Invalid under the laws of any political body having jurisdiction over
the subject matter hereof, such contravention or invalidity shall not invalidate
the entire Agreement, but, instead, this Agreement shall be construed as if not
containing the particular provision or provisions held to be invalid and the
rights and obligations of the parties shall be construed and enforced
accordingly and this Agreement shall thereupon and thereafter remain in full
force and effect.

29.       Confidentiality and Ancillary Agreements.

     For and in consideration of the mutual covenants and provisions hereof,
Buyer and Seller shall contemporaneously with the execution of this Agreement
execute and deliver to the other a Confidentiality Agreement and Ancillary

     The parties to this Agreement having been represented by legal counsel of
their own choosing in connection with the negotiation and drafting of this
Agreement, this Agreement shall be construed and interpreted for all purposes
without regard to the author of any specific language appearing herein. The
headings contained in this Agreement are for reference purposes only and shall
not affect in any way the meaning or interpretation of this Agreement.

31.  Option Platform.

     (a)Seller hereby grants to Buyer an option (the "Option"), subject to and
conditioned upon no prior commitment of the production resources of Seller to
other customers before Buyer notifies Seller of its exercise of the Option, to
have Seller construct and sell to Buyer a 

                                          26


<PAGE>


mobile, self contained and elevating platform with the same specifications as
the Platform (the "Option Platform") for a fixed purchase price (without the
LeTourneau Kit) of (i) USD $47,000,000.00 (the "Fixed Purchase Price") if the
Option is exercised by December 1, 1997 and LeTourneau commits to deliver the
Kit for the Option Platform not later than June 30, 1999 and with a scheduled
delivery date no later than February 28, 2000 (the "Scheduled Delivery Date").
If either the Option is exercised after December 1, 1997 or LeTourneau commits
to deliver the LeTourneau Kit for the Option Platform after June 30, 1999 or the
components of the LeTourneau Kit are delivered by LeTourneau out of sequence
with Seller's construction schedule, the Fixed Purchase Price shall escalate by
one (1 ) percent per month or part thereof for the period of delay and the
initial Scheduled Delivery Date should be extended by the same number of days.
In consideration for the granting of this Option to Buyer, Buyer hereby agrees
that it will not seek to purchase or have constructed another LeTourneau 116
platform from any other source (not including Seller's affiliated companies)
during the period of the Option.  Buyer may terminate this obligation not to
construct or purchase another LeTourneau 1 16 platform at any time after
December 1, 1997 by notice to Seller, but the Option shall thereupon lapse
automatically.

     (b)       The purchase price excluding the LeTourneau Kit for the Option
Platform shall be paid on the following schedule:

     (i)       Contract Signing              15%
     (ii)      Start Fabrication/2000 tons of
               steel delivered               15%
     (iii)     Lay keel                      20%
     (iv)      Install 3rd spud can          20%
     (v)       Launch                        20%
     (vi)      Delivery                      20%

The above milestone payments mentioned above shall become due upon completion of
each event. The price for the LeTourneau Kit for the Option Platform shall be
paid by Buyer to Seller in immediately available funds as and when Seller is
obligated to make payment therefor to LeTourneau.

     (c)  The Option must be exercised by Buyer by written notice delivered to
the Seller as provided in Section 19 hereinabove by July 31, 1998 or the same
shall automatically terminate. The Option is further subject to and conditioned
on LeTourneau's commitment to a delivery date for the LeTourneau Kit of not
later than March 1, 2000 and ability of Seller due to lack of prior commitments
to deliver the Option Platform before October 31, 2000 and if either or both
condition is not fulfilled, the Option shall automatically terminate.

                                          27

<PAGE>


     (d)  The Option Platform shall be constructed by Seller and purchased by
Buyer pursuant to a Platform Construction Contract containing the terms of
Section 31 (a) above as to price and scheduled delivery date, the terms of
Section 31(b) above as to the payment schedule, and the terms and conditions of
this Agreement as to other provisions.

     (e)  Buyer's obligation to purchase the Option Platform after exercise of
the Option and Seller's obligation to construct and sell the Option Platform to
Buyer after exercise of the Option shall be subject and conditioned upon:

          (i)  Presentation by Seller within fifteen (15) days of the exercise
of the Option of written price and delivery schedule for a LeTourneau Kit for
the Option Platform (provided LeTourneau will commit to a firm price
and delivery).

          (ii) Commitment in writing by Seller within fifteen (15) days of the
exercise of the Option of a revised purchase price for the Option Platform based
on the LeTourneau Kit price and any other changes to the Option Platform
requested by Buyer.

          (iii)     Notice by Buyer that within the fifteen (15) day period
referred to in (i) above that after review of the revised price and delivery
schedule referred to in (i) above Buyer, wishes to proceed with the Option. If
Buyer fails to give such notice within the required time or notifies Seller that
it does not wish to proceed with the Option, the Option shall terminate and
Buyer shall have no further rights in or to the Option Platform.
     
          (iv) The negotiation and execution of contracts between Seller and
LeTourneau including an ancillary agreement and confidentiality agreement, in
form and substance satisfactory to Seller, Buyer, and LeTourneau.

          (v)  Performance by LeTourneau under the LeTourneau Agreements.

     (f)  As used herein, the LeTourneau Kit shall mean the elevating units, leg
material, cranes, skidding systems, and raw water tower elevating system for a
LeTourneau Super 116 platform.

December 18, 1997


Mr. John C. Purvis
Vice President - Marketing
AMFELS, Inc.
5177 Richmond Avenue, Suite 1065
Houston, TX 77056

Dear John:

     Based on our further discussions and correspondence, enclosed, please
find a revised letter agreement to modify the terms of Chiles' existing
option rig and an agreement to provide Chiles with two further options to
build similar rigs at AMFELS.

Option
Rig No. 1:               AMFELS agrees to modify Chiles' existing option in
                         the contract for Rig No. 2 for one LeTourneau
                         Super 116, as outlined herein ("Option Rig No.
                         1").  The price for Option Rig No. 1 is $48.5
                         million (excluding the "Kit" but including the
                         design changes which have been contractually
                         agreed to-date on Rig No. 1 and 2) and the option
                         will expire on July 31, 1998 but will increase in
                         price by $1 million on April 30, 1998 unless the
                         option was previously exercised.   AMFELS agrees
                         to deliver Option Rig. No. 1 on the date which is
                         the later of:  (a) December 15, 1999 or (b) 20
                         months from the date of entering into a final
                         contract, subject to timely delivery and
                         acceptable price of the LeTourneau "Kit" (see
                         schedule below).

<PAGE>

Option
Rig No. 2:               AMFELS agrees to provide Chiles with an option for
                         one sister rig ("Option Rig No. 2") by entering
                         into a contract for Option Rig No. 1.  Option Rig
                         No. 2 has to be exercised prior to December 15,
                         1998.  The price is fixed at $48.5 million
                         (excluding the "Kit" but including the design
                         changes which have been contractually agreed
                         to-date on Rig No. 1 and 2) through June 30, 1998
                         at which time the price of the rig will increase
                         by $1 million.  AMFELS agrees to deliver Option
                         Rig. No. 2 on the date which is the later of: (a)
                         April 15, 2000 or (b) 20 months from the date of
                         entering into a final contract, subject to timely
                         delivery and acceptable price of the LeTourneau
                         "Kit" (see schedule below).

Option
Rig No. 3:               AMFELS agrees to provide an option for one sister
                         rig ("Option Rig No. 3") as a result of Chiles
                         entering into a contract for Option Rig No. 2. 
                         Option Rig No. 3 has to be exercised prior to
                         March 31, 1999 and the pricing would be the best
                         price offered by AMFELS to any customer for a
                         LeTourneau Super 116 at the time for the first
                         available delivery position on a "first come -
                         first served" basis.

Contract Form:           AMFELS and Chiles agree to enter into an amendment
                         of the contract for Rig No. 2 substantially in the
                         form of Clause 31 of the contract, subject to any
                         and all changes necessary thereto in order to
                         reflect the terms of this agreement.

                         The form of contract and amendment shall among
                         other things provide for the ability to provide a
                         construction lender with a first preferred
                         security interest in the rigs during the
                         construction period.

Exclusivity:             Chiles agrees that as long as any option described
                         above remains outstanding and in effect it shall
                         not order any similar premium jackup rigs at a
                         competing shipyard without first having received
                         AMFELS' approval in writing and AMFELS shall
                         supply the requirements of Chiles for LeTourneau
                         premium jackup rigs as contemplated by this letter
                         agreement.

LeTourneaus "Kits"):     The above options are based on the following
                         prices for LeTourneau Kits

                              Option 1       $22.50 million
                              Option 2       $24.75 million
                              Option 3       $27.20 million

                         If upon exercise of an option, the "Kit" price is
                         in excess of the respective amounts listed above,
                         Chiles shall have the right to cancel the option
                         provided it concurrently exercises its next
                         option, if any.

                         If a "Kit" delivery is not available on a timely
                         basis making it impractical for AMFELS to comply
                         with the agreed upon delivery date as per the
                         specific option then Chiles may either accept a
                         revised delivery schedule by mutual consent of
                         both parties or cancel the option and concurrently
                         exercise its next option, if any.  The mechanism
                         for exercising the options shall be modified to
                         provide that Chiles must exercise its options
                         after the receipt of the applicable quote from
                         LeTourneau, subject to qualifications set forth
                         herein, concerning price and delivery of the
                         applicable "Kit".

     Should you accept this agreement it would allow Chiles to immediately
start the process of raising expansion capital on the basis of the above
described options.

     We hope that you find the above in form and substance acceptable.

                                        3

                               CHILES OFFSHORE LLC

                             1998 EQUITY OPTION PLAN





     1. PURPOSES

     1.1. Chiles Offshore LLC, a Delaware limited liability company (the
"Company"), desires, by means of this 1998 Equity Option Plan (the "Plan") and
options to be granted hereunder, to afford to certain key employees of the
Company, or any Subsidiaries (as hereinafter defined), or consultants to such
companies, who are responsible for increasing the value of the Company, an
opportunity to acquire Membership Interests (as hereinafter defined) in the
Company and, thereby, to create in such persons an increased interest in, and a
greater concern for, the welfare of the Company and its subsidiaries. The
Company, by means of this Plan and options to be granted hereunder, also seeks
to retain the services of persons now holding key positions and to secure the
services of persons capable of filling such positions.

     1.2. Options issued pursuant to this Plan ("Options") shall be a matter of
separate inducement for, and are not to be granted in lieu of any salary or
other compensation for, the services of a key employee or consultant.

     2. MEMBERSHIP INTERESTS SUBJECT TO OPTIONS

     2.1. Options granted under this Plan shall be applicable to the acquisition
of, and only to the acquisition of, (i) Membership Interests created under the
Operating Agreement (as hereinafter defined), with the owners thereof being
designated as "Group D Members," or (ii) any Substitute Interests (as hereafter
defined) delivered after the Effective Date (as hereinafter defined) in exchange
for, or otherwise in respect of such Membership Interests in accordance with the
provisions of paragraph 12.4 of this Plan (collectively, "Group D Membership
Interests").

     2.2. In addition, Options may be issued under the Plan only to the extent
that the total amount of all Group D Membership Interests which may be acquired
pursuant to the exercise of Options then and theretofore granted under the Plan
(the "Eligible Membership Interests") shall not exceed, in the aggregate, 5.0%
of the Membership Interests at the time outstanding on a fully diluted basis
(assuming the exercise of all Options); provided, however, that such 5.0%
limitation shall be 

<PAGE>

subject to adjustment by the Option Committee as provided in paragraph 12.5
hereof and that any reduction in Membership Interests outstanding shall not
invalidate any already outstanding Options. The Eligible Membership Interests as
of the Effective Date represent interests in the Company's equity that, based on
the Initial Value (as hereinafter defined) of the Company's equity, have a value
of U.S. $3,250,000.

     2.3. Options shall initially be granted under this Plan as of the Effective
Date (the "Initial Grant") to certain key executives with respect to an
aggregate amount of Eligible Membership Interests equal to approximately 3.953%
of the Member Interests in the Company as of the Effective Date, having an
Initial Value on the Effective Date of $2,569,450. The Options comprising the
Initial Grant shall expire on the tenth anniversary of the Effective Date.

     2.4. This Plan shall be effective beginning as of 9:00 A.M. E.S.T. as of
March 31, 1998 (the "Effective Date"). The "Initial Value" of the Company's
equity for purposes of this Plan has been determined to be U.S. $65 million,
representing the Value (as hereinafter defined) of all the Membership Interests
in the Company on the Effective Date as determined by the Option Committee (as
hereinafter defined).

     2.5. Subject to Section 18 hereof, Options under this Plan may be granted
from time to time during the period beginning on the Effective Date and ending
on March 31, 2008 (the "Grant Expiration Date") on the terms and conditions
hereinafter provided, unless and until Options have been granted hereunder for
all the Eligible Membership Interests, and no Options shall be granted after the
Grant Expiration Date.

     3. ADMINISTRATION

     3.1. The Management Committee of the Company (the "Management Committee")
shall designate from any of its members a committee, which may be the
Compensation Committee of the Management Committee as the same may from time to
time be constituted, to administer this Plan (the "Option Committee"). The
Option Committee shall consist of no fewer than two (2) members, each of whom
(i) shall not be a holder of an Option or a person eligible to receive a grant
of Options hereunder and (ii) if any equity security of the Company is
registered under Section 12 of the Securities Exchange Act of 1934, as amended
and as the same may be amended and any successor provision of law (the "Exchange
Act"), or are subject to the reporting requirements of Section 15(d) of the
Exchange Act, shall be with respect 


                                       2
<PAGE>

to the Company "non-employee directors" within the meaning of Rule 16b-3 (or any
successor rule or regulation) promulgated under the Exchange Act. A majority of
the members of the Option Committee shall constitute a quorum for a meeting of
the Option Committee, and the act of a majority of the members of the Option
Committee shall be the act of the Option Committee. The rules and procedures of
the Option Committee shall otherwise be determined by the Management Committee
or the Option Committee. Any member of the Option Committee may be removed at
any time either with or without cause by resolution adopted by the Management
Committee, and any vacancy on the Option Committee at any time may be filled by
resolution adopted by the Management Committee.

     3.2. Subject to the express provisions of this Plan, on an annual or more
frequent basis, as the Option Committee or the Management Committee shall
determine, the Option Committee shall determine, in its discretion, the persons
to whom Options shall be granted (together with permitted assigns thereof, the
"Participants"), the units of Eligible Membership Interests which shall be
subject to each Option, the purchase price for Eligible Membership Interests
under each Option, the period(s) during which such Options shall be exercisable
(whether in whole or in part) and the other terms and provisions thereof (which
need not be identical). The Option Committee may establish performance standards
for determining the periods during which Options shall be exercisable, including
without limitation standards based on the earnings of the Company for various
fiscal periods. The Option Committee shall define such performance criteria and,
from time to time, the Option Committee in its sole discretion and in
administering this Plan may make adjustments to such performance criteria for
any fiscal period so that extraordinary or unusual charges or credits,
acquisitions, mergers, consolidations, and other corporate transactions and
other elements of or factors influencing the calculations of earnings or any
other performance standard do not distort or affect the operation of this Plan
and Options granted hereunder in a manner inconsistent with the achievement of
the purposes of this Plan.

     3.3. Subject to the express provisions of this Plan, the Option Committee
also shall have authority to construe the terms and conditions of this Plan and
the Options granted thereunder, to amend this Plan and the Options granted
thereunder, to prescribe, amend and rescind rules and regulations relating to
this Plan, and to make all other determinations necessary or advisable for
administering this Plan. The Option Committee may employ such legal counsel,
consultants and agents as it may deem desirable for the administration of this
Plan and may rely upon any opinion or computation received from any such legal
counsel, consultant or agent. 

                                       3
<PAGE>

Expenses incurred by the Option Committee in the engagement of such counsel,
consultant or agent shall be paid by the Company. No member or former member of
the Option Committee shall be liable for any action or determination made in
good faith with respect to any grant of Options hereunder or the interpretation
or application of the terms and conditions of the Plan or any Option or
otherwise with respect to this Plan. The determination of the Option Committee
on matters referred to in this Section 3 shall be conclusive.

     4. ELIGIBILITY

     4.1. Options may be granted only to key employees of the Company or a
Subsidiary thereof, or a consultant providing substantial services thereto, and
shall not be granted to any member of the Option Committee.

     4.2. The adoption of this Plan does not create a right in any employee or
consultant to participate in the Plan, nor does it create a right in any
employee or consultant to have any Options granted to him or her under this
Plan.

     5. OPTION PRICE, UNITS AND PAYMENT

     5.1. For purposes hereof, each unit of Eligible Membership Interest (a
"Unit") shall be equal to 0.001% all the Membership Interests in the Company at
the time of grant. Accordingly, the purchase price of each Unit subject to an
Option granted as part of the Initial Grant shall be $650, representing 0.001%
of the Initial Value on the Effective Date. Upon the exercise of any Option, the
Participant shall receive a Group D Membership Interest that represents the
Group D Membership Interest the Participant would then own if the Participant
had exercised such Option on the date of grant. By way of example, if an Option
is exercised for 10 Units (i.e., representing 0.01% of all Membership Interests
in the Company on the date of grant), the Participant would receive a Group D
Membership Interest representing a 0.01% Percentage Interest in the Company if
there have been no sales or repurchase of Membership Interests by the Company
(or similar events affecting Percentage Interests) between the date of grant and
the date of exercise; however, if the Company for example sold additional
Membership Interests between the date of grant and the date of exercise
resulting in the Members on the date of grant experiencing a 20% dilution of
their Percentage Interests, the optionholder would receive a Group D Membership
Interest representing a 0.008% Percentage Interest in the Company upon such
exercise.

                                       4
<PAGE>

     5.2. The purchase price for each Eligible Membership Interest subject to an
Option granted after the Initial Grant shall be such amount, not less than the
Value thereof on the date the Option is granted, as shall be determined by the
Option Committee. For purposes of the Plan, the "Value" of an Eligible
Membership Interest shall be as determined in accordance with this paragraph. If
Eligible Membership Interests of the kind subject to the Option are at the time
listed on a national securities exchange or quoted in an inter-dealer quotation
system, which in either case is authorized under the Exchange Act, then the
Value of an Eligible Membership Interest on any date shall be the last sale
price on such date, if a trading day, or on the most recent past trading day
reported in the transaction reporting system therefor authorized under the
Exchange Act. If the Membership Interests are not so listed or traded, then the
Value of an Eligible Membership Interest shall be the fair market value of such
Eligible Membership Interest, as determined by the Option Committee in good
faith by any means reasonably determined by the Option Committee. For purposes
of this Plan, the determination by the Option Committee of the Value of an
Eligible Membership Interest shall be conclusive.

     5.3. Unless a non-cash payment has been approved by the Option Committee,
the purchase price for an Eligible Membership Interest payable upon exercise of
an Option shall be payable, unless otherwise agreed by the Company, in cash, by
certified bank check, in immediately available federal funds delivered to an
account designated by the Company or by personal check of the Participant,
subject to collection; provided that, if paid by personal check of the
Participant, unless waived by the Company, payment shall not be deemed received
until the Company shall have collected thereon.

     6. GRANT, VESTING AND OTHER TERMS OF OPTIONS; LIMITATION ON THE RIGHT OF
        EXERCISE

     6.1. An Option shall vest and be exercisable at such times, in respect of
the Units subject thereto, and at such price or prices and during such period or
periods, and on such other terms and conditions, consistent with the provisions
of this Plan, as the Option Committee shall determine on or before the date of
the grant of such Option; provided, however, that an Option shall not be
exercisable after the expiration of ten (10) years from the date such Option is
granted. A grant of Options hereunder shall be made by the delivery by the
Company to the individual granted the Option of an Option Agreement
substantially in the form attached hereto as Exhibit A, or substantially in such
other form as the Option Committee shall have approved, which Option Agreement
shall specify the time or times at which such Option shall 

                                       5
<PAGE>

vest and shall be exercisable, the Units in respect of which, the price or
prices at which and the period or periods during which such Option shall be
exercisable and any other terms of the Option; provided, however, that, if any
such term (other than the Units for which such Option may be exercisable) is not
so specified, the Option shall (i) subject to Section 11 hereof, have a term
extending from the date of grant to the tenth anniversary of the date of grant,
(ii) subject to Section 6.2, vest and become exercisable in three equal
installments, on the first, second and third anniversaries of the date of grant,
and the number of Units for which such Option shall vest and may be exercised on
such installment dates shall be equal in amount, (iii) the price at which such
Option shall be exercisable shall be the Value of the Units subject thereto on
the date of grant, and (iv) all other terms and conditions of such Option shall
be as provided by this Plan.

     6.2. Unless otherwise determined by the Option Committee, no Option may be
exercised prior to the completion of construction of the two premium jackup
drilling rigs (one LeTourneau Enhanced 116-C and one LeTourneau Super 116) that
are currently being constructed for the Company at AMFELS, Inc. (collectively,
the "Initial Premium Jackup Drilling Rigs").

     6.3. The Option Committee shall have the right to accelerate, in whole or
in part, from time to time, conditionally or unconditionally, the right to
exercise any Option granted hereunder.

     6.4. To the extent that an Option is not exercised within the period of
exercisability specified therein, it shall expire as to the then unexercised
part.

     6.5. In no event shall an Option granted hereunder be exercised for a
Membership Interest in an amount less than a Unit or a comparable amount of
Substitute Interests issued pursuant to Section 12 hereof in exchange therefor.

     7. EXERCISE OF OPTIONS

     7.1. Subject to Section 9 and any additional requirements that may be
provided by an Option Agreement, Options granted under this Plan shall be
exercised by the Participant by the giving of written notice of the exercise
thereof to the Company, Attention: Secretary, at the principal business office
of the Company, specifying the number of Units to be purchased upon such
exercise, such notice to be substantially in the form provided by Exhibit B to
the form of Option Agreement attached hereto as Exhibit A hereto. Unless the
Company shall otherwise agree in

writing, such notice shall be accompanied by (i) the tender of payment of the
purchase price for the Units to be purchased upon such exercise of the Option,
in accordance with the requirements of Section 5 hereof, and (ii) the Option
Agreement issued with respect to the Option (and not a copy thereof), which in
the case of a permitted partial exercise shall be endorsed by the Company to
reflect such partial exercise and returned to the optionholder (and in the case
of exercise in full shall be retained by the Company). The Company may also
require an optionholder in connection with the exercise of an Option to execute
and deliver to it or to the Company the documents referred to in Section 14
hereof and any documents that may be required under the Operating Agreement in
connection with the admission of a person as a member of the Company or the
transfer of an additional Membership Interest to a person who is already a
member of the Company, as may be appropriate to the circumstances. The Company
shall advise the optionholder of any such additional documentation requirements
in connection with the exercise of an Option promptly after it has received
notice of exercise of the Option. The Company may waive any of the foregoing
requirements respecting the manner of exercise of Options.

     7.2. Upon receipt by the Company of notice of exercise of an Option in
accordance with paragraph 7.1 hereof, the Company shall, subject to the terms of
Sections 9, 14 and 15 hereof, cause the Membership Interest purchased upon
exercise to be recorded in the name of the Participant or his designee in
accordance with the Operating Agreement, against payment of the full purchase
price and execution and delivery of any other required documentation, on the
date therefor specified in the notice of exercise (or on such earlier date or by
such other means of delivery as is acceptable to the Company and the
optionholder).

     8. CERTAIN DEFINITIONS

     For purposes hereof, the following terms shall have the respective meanings
provided below in this Section 8:

     8.1. "Affiliate" of a person or entity means any other person or entity
controlled by, controlling or under common control with such person or entity,
for which purpose "control" shall have the same meaning as used in the
Securities Exchange Act.

     8.2. "Business Day" shall mean any day except a Saturday, Sunday or other
day on which the principal business office of the Company is closed.

                                       7
<PAGE>

     8.3. "Membership Interest" shall have the meaning set forth in the
Operating Agreement.

     8.4. "Operating Agreement" shall mean the Amended and Restated Operating
Agreement of the Company, dated as of December 16, 1997, by and among the
persons signatory thereto and such other persons as may become members in
accordance therewith, as the same may be amended or modified from time to time
in accordance with its terms; provided, however, that, if interests in or
securities of a company other than the Company have been issued in exchange or
substitution for Membership Interests and then outstanding Options become
exercisable for such interests or securities in accordance with Section 12
hereof, then "Operating Agreement" shall refer to the certificate of
incorporation and by-laws, partnership agreement or like constitutive documents
of the issuer of such interests or securities.

     8.5. "Subsidiary" shall mean any corporation, partnership, limited
liability company or like entity controlled by the Company of which at least 50%
of the equity interest therein is owned, directly or indirectly, by the Company.

     9. REPURCHASE OF OPTIONS

     9.1. Following the Company's receipt of a notice of exercise of any Option
by a Participant in accordance with Section 7.1 (the date of such receipt, with
respect to such Option, being referred to as the "Option Exercise Date") other
than a notice of exercise furnished following a termination of employment or of
a consulting engagement due to dismissal of a Participant without Cause as
contemplated by Section 11.1(b), the Company may elect, by written notice to
such Participant given within ten (10) Business Days after the Option Exercise
Date, to repurchase the Options that would otherwise be exercised at a
repurchase price determined in accordance with the provisions of Section 9.2. In
the event that the Company makes such election, the Company shall provide notice
of such repurchase price to the Participant promptly after the determination
thereof, which notice shall specify that such repurchase price is payable in
cash or, in the event that the provisions of Section 9.4 are applicable, the
terms and conditions of such repurchase in accordance therewith. The Participant
shall have the right, exercisable by written notice to the Company within ten
(10) days following receipt of the Company's notice of such repurchase price, to
withdraw his or her notice of exercise. If the Participant waives such right or
does not so withdraw his or her notice of exercise, the Company shall repurchase
the Options to which such notice of exercise relates in accordance with the
provisions of Section 9.3.

                                       8
<PAGE>

     9.2. The repurchase price for each Unit of Eligible Membership Interests
subject to an Option shall be such amount, not less than the Value thereof on
the Option Exercise Date, as shall be determined by the Option Committee. For
purposes of the Plan, the "Value" of any Unit of Eligible Membership Interests
shall be as determined in accordance with this paragraph. If Eligible Membership
Interests of the kind subject to the Option are at the time listed on a national
securities exchange or quoted in an inter-dealer quotation system, which in
either case is authorized under the Exchange Act, then the Value of an Eligible
Membership Interest (or Unit thereof) on any date shall be determined by
reference to the last sale price on such date, if a trading day, or on the most
recent past trading day reported in the transaction reporting system therefor
authorized under the Exchange Act. If Membership Interests of the kind subject
to the Option are not so listed or traded, then the Value of any Unit of
Eligible Membership Interests shall be the fair market value of such Unit, as
determined by the Option Committee in good faith by any means reasonably
determined by the Option Committee; provided, however, that, in determining such
Value, the Option Committee shall give due consideration to the market value of
companies engaged in comparable businesses whose equity securities are at the
time listed on a national securities exchange or quoted in an inter-dealer
quotation system and, provided further, that in no event shall the value of any
Unit of Eligible Membership Interests as so determined to be less than the
Percentage Interest that would be represented by such Unit upon exercise of the
amount, if any, by which (a) the sum of (i) the product of (A) four and (B) the
amount of the Company's consolidated earnings before interest, taxes,
depreciation and amortization for the most recently completed 12 month period
that ended on or prior to the Option Exercise Date, determined in accordance
with generally accepted accounting principles, and (ii) the amount of cash and
value of marketable securities owned by the Company as of the Option Exercise
Date exceeds (b) the aggregate amount of the Company's indebtedness (including
obligations under capitalized leases) and the amount of any reserves for
contingent liabilities established as of the Option Exercise Date. For purposes
of this Plan, the determination by the Option Committee of the Value of any Unit
of Eligible Membership Interests thereof shall be conclusive.

     9.3. In the event that any applicable Participant does not withdraw his or
her notice of exercise within the ten-day period following his or her receipt of
the Company's notice of repurchase as provided in Section 9.1 hereof, within
five (5) Business Days after the expiration of such ten-day period, on a
Business Day and at a time during normal business hours designated by the
Company by notice to such Participant, the Company shall repurchase the Options
to be so sold to it by the Participant for cash, certified bank check or
immediately available funds in the 

                                       9
<PAGE>

amount of the repurchase price (or such other consideration as the Company may
have specified in its notice of the repurchase price in the event that the
provisions of Section 9.4 are applicable) against delivery of the Participant's
Option Agreement to the Company at its principal business office for
cancellation or, if only part of Option evidenced by such Option Agreement are
sold, for annotation to such effect. The Participant shall execute and deliver
such documents as the Company may reasonably request to document such
transaction. Upon repurchase by the Company of an Option, the Option shall
automatically expire.

     9.4. Notwithstanding anything to the contrary contained herein, the
following provisions shall apply:

     (a) The Company's obligations to make payments to any Participant under the
Plan shall at all times and in all respects be subject, subordinate and junior
in right of payment to all borrowings, secured or unsecured, now owing or which
hereafter may become owing, and all leases, of the Company and its Subsidiaries,
and the Company shall not be obligated to make any payment under the Plan if the
Company upon or after such payment would be in default under any instrument or
agreement to which the Company is a party or by which the Company or any of its
assets is materially bound or affected. If the Company does not make any agreed
payment under the Plan by reason of the preceding sentence, such payment shall
be deferred until such time as it may be made without default under any such
instrument or agreement, and in the interim period the deferred amount shall
accrue interest, at the Company's then current cost of borrowed funds, as
determined by the Option Committee.

     (b) In repurchasing any Options (or portions thereof), the Company, acting
by the Option Committee, may elect, if the total repurchase price is in excess
of $500,000, to pay such repurchase price in three (3) equal payments equal to
one-third (1/3) of the repurchase price (together with interest at the Company's
then current cost of borrowed funds, as determined by the Option Committee), the
first of such payments to be made within thirty (30) days after the date of
determination of such repurchase price and the additional installments to be
made on the first and second anniversaries of the date of the initial payment.

     (c) The Company's obligation to pay any repurchase price, if deferred,
shall be prepayable by the Company, together with accrued interest, in whole or
in part at any time without penalty. Further, in the event of a Change in
Control of the Company as described in Section 12.1, all Participants not
previously

                                       10
<PAGE>

paid their repurchase prices in full shall on the date of the occurrence of such
Change in Control receive payment in full of the Company's then remaining
obligations to them hereunder. The death or disability of a Participant or any
termination of employment shall not accelerate the Company's payment obligations
under this Section 9.4, which shall continue in effect to the Participant and/or
his or her legal representatives, as the case may be.

     10. NON-TRANSFERABILITY OF OPTIONS

     No Option granted hereunder shall be transferable, whether by operation of
law or otherwise, other than by will or the laws of descent and distribution,
and any Option granted hereunder shall be exercisable during the lifetime of the
holder only by such holder; provided, however, that an Option may be transferred
by the holder thereof by gift to a member of his or her family or to a trust
principally for the benefit thereof pursuant to such documents respecting such
transfer as are reasonably satisfactory to the Company. Except to the extent
provided above, Options may not be assigned, transferred, pledged, hypothecated
or disposed of in any way (whether by operation of law or otherwise) and shall
not be subject to execution, attachment or similar process, and any purported
assignment in contravention hereof shall be void and of no effect.

     11. TERMINATION OF EMPLOYMENT

     11.1. Upon termination of the employment of a Participant with the Company
and any Subsidiary thereof or, in the case of a Participant who is a consultant,
termination of all of his consulting engagements with the Company and any
Subsidiary thereof, the following provisions shall, unless otherwise provided in
the Option Agreement, apply to the Participant's Options (including any Options
held by a permitted transferee):

          (a) If termination of employment or of the consulting engagement is
     due to Cause (as defined below), the Option shall, unless otherwise
     specified by the Option Committee in writing not later than the date of
     such termination, automatically terminate as of the date of termination of
     employment or of the consulting engagement with respect to any then
     unexercised portion of the Option.

          (b) If termination of employment or of the consulting engagement is
     due to dismissal without Cause, the Option, to the extent 

                                       11
<PAGE>

     not theretofore exercised, shall become immediately exercisable and shall
     be considered vested and the Participant shall have the right to exercise
     the Option, to the extent not theretofore exercised, in respect of any or
     all the Eligible Membership Interests subject thereto at any time up to and
     including the ninetieth (90th) day after the date of such termination (but
     subject to paragraphs 6.2 and 11.8 hereof).

          (c) If termination of employment or of the consulting engagement is
     due to retirement, resignation of the Participant or Disability (as defined
     below) and at such time the Participant was entitled to exercise the
     Option, the Option to the extent then exercisable shall be considered
     vested and the Participant shall have the right to exercise the Option, to
     the extent not theretofore exercised, in respect of any or all the Eligible
     Membership Interests that such Participant was entitled to purchase
     pursuant to the Option at the time of such termination, at any time up to
     and including (i) in the case of retirement or resignation, the ninetieth
     (90th) day after the date of such termination or (ii) in the case of
     termination by reason of Disability, one (1) year after the date of such
     termination (but subject to paragraphs 6.2 and 11.8 hereof). All Options
     granted to such participant that are not vested as of the date of such
     termination shall automatically terminate.

          (d) If termination of employment or of the consulting engagement is
     due to the death of the Participant and at such time the Participant was
     entitled to exercise the Option, the Option to the extent then exercisable
     shall be considered vested and the Participant's legal representative, or
     the person who acquired the Option by bequest or inheritance upon the death
     of the Participant, shall have the right to exercise the Option so granted,
     to the extent not theretofore exercised, in respect of any or all the
     Eligible Membership Interests that such Participant was entitled to
     purchase pursuant to the Option at the time of such Participant's death, at
     any time up to and including one (1) year after the date of death (but
     subject to paragraphs 6.2 and 11.8 hereof). All Options granted to such
     Participant that are not vested as of the date of death shall automatically
     terminate.

     11.2. If an Option granted hereunder shall be exercised by the legal
representative of a deceased or disabled Participant, or by a person who
acquired an 

                                       12
<PAGE>

Option granted hereunder by bequest or inheritance or by reason of death of any
Participant, written notice of such exercise shall be accompanied by a certified
copy of letters testamentary or equivalent proof of the right of such legal
representative or other person to exercise such Option.

     11.3. Upon the occurrence of a termination of a Participant's employment or
of all consulting engagements as described in subparagraphs (b), (c) or (d) of
Section 11.1 above, the Participant (or his legal representative) may, if an
Initial Public Offering has not occurred, direct that the Company repurchase
such Participant's Options on the terms and conditions provided by Section 9
hereof, substituting, however, the date of such termination for the Option
Exercise Date and the most recent month-end of the Company before such
termination as the date of valuation. In such event, the optionholder shall be
required to sell, and the Company shall be required to purchase, the Option on
such terms. For purposes of this Plan, an "Initial Public Offering" means an
initial public offering of Membership Interests or Substitute Interests that is
closed by the sale of Membership Interests or Substitute Interests pursuant to
the Company's first effective Registration Statement for the sale of Membership
Interests or Substitute Interests filed under the Securities Act of 1933, as
amended, and as the same may be amended from time to time, or any successor
provision of law (the "Securities Act").

     11.4. For purposes of this Section, the term "Cause" shall mean (A) fraud,
embezzlement or gross insubordination on the part of the Participant or breach
by the Participant of his or her obligations under any Company policy or
procedure; (B) conviction of or the entry of a plea of nolo contendere by the
Participant for any felony; (C) a material breach of, or the willful failure or
refusal by the Participant to perform and discharge, his or her duties,
responsibilities or obligations as an Participant; or (D) any act of moral
turpitude or willful misconduct by the Participant which (A) is intended to
result in substantial personal enrichment of the Participant at the expense of
the Company or any of its subsidiaries or affiliates or (B) has a material
adverse impact on the business or reputation of the Company or any of its
subsidiaries or affiliates; provided, however, that with respect to a
Participant who is a party to a written employment or consulting agreement with
the Company, which agreement contains a definition of "for cause" or "cause" (or
words of like import) for purposes of termination of employment thereunder by
the Company, the term "Cause" shall mean, "for cause" or "cause" as defined in
the most recent of such agreements.

                                       13
<PAGE>

     11.5. For purposes of this Section 11, the term "Disability" shall mean the
inability (as determined in good faith by the Option Committee) of such
Participant, as a result of incapacity due to physical or mental illness or
disability, to perform the duties for which the Participant is employed for six
consecutive months or shorter periods aggregating six months during any
twelve-month period.

     11.6. A termination of employment shall not be deemed to occur by reason of
the transfer of a Participant from employment by the Company to a Subsidiary of
the Company. If an individual to whom an Option is granted transfers an Option
as permitted by this Plan, a termination of the employment or consulting
engagement of the individual to whom the Option was granted shall have the same
effect on the Option in the hands of the transferee as it would have had in the
hands of such individual.

     11.7. In the case of any Participant who is a consultant and not an
employee, the foregoing provisions of this Section 11 shall be applied with
respect to termination of such Participant's consulting services as the Option
Committee shall determine to be substantially equivalent in respect of such
relationship to the result that would have ensued if such Participant had been
an employee.

     11.8. Notwithstanding anything to the contrary contained in this Section
11, in no event shall any person be entitled to exercise any Option after the
expiration of the period of exercisability of such Option as specified herein or
in the Option Agreement relating thereto.

     12. EFFECT OF CERTAIN TRANSACTIONS

     Change in Control

     12.1. For purposes of this Plan, a "Change in Control" of the Company shall
mean any of, and shall be considered to have occurred upon the acquisition by
any person or group of persons acting in concert other than SEACOR Offshore Rigs
Inc. or COI, LLC, or any Affiliate of either such entity, of the right to elect
a majority of the Management Committee (or any successor governing body).

     12.2. Upon the occurrence of a Change of Control of the Company, the
Company (or its successor) will give written notice thereof to each Participant
promptly (and in any event within five Business Days) and each Option or portion
of 

                                       14
<PAGE>

an Option that has not vested will vest as of the date of such Change of
Control. Upon the occurrence of a Change of Control of the Company, (i) a
Participant may, by notice to the Company, require the Company (or its
successor) to purchase for cash all or any of his Options in accordance with the
provisions applicable to the purchase of Options under Section 9 hereof, but
based on the Value of the Eligible Membership Interests as of the date of such
Change of Control, and (ii) the Company (or its successor) may, by notice to any
Participant, require such Participant to sell all his Options in accordance with
the same provisions. For purposes of applying Section 9 hereof with respect to
any such purchase, the date of such Change of Control shall be substituted for
the Option Exercise Date. Notice of the exercise of the rights of a Participant
or the Company under this Section 12.2 may be furnished to the other prior to,
on or after (but not later than thirty (30) days after) the date of the Change
of Control. The closing of any purchase and sale of Options pursuant to this
Section 12.2 shall take place at such time and place as shall be specified by
notice in writing from the Company to the Participant.

     Initial Public Offering

     12.3. In the event an Initial Public Offering occurs, all Options will
continue in effect, and continue to vest and become exercisable in accordance
with the provisions of the Plan and the Option Agreement.

     Incorporation or Merger of the Company Into a Successor

     12.4. Except in the case of the occurrence of a transaction described in
Section 12.1 hereof (in which case the provisions thereof shall instead be
applicable), in the event of the incorporation of the Company or a merger,
consolidation or like transaction between the Company and another company as a
result of which Membership Interests are exchanged for or converted or changed
into shares of capital stock of a corporation or interests in a partnership,
limited liability company or trust, or notes, debentures, bonds or other debt
instruments or other securities or other property or cash, or any combination
thereof ("Substitute Interests"), the Options outstanding at that time will
continue, whether or not then vested or exercisable, as obligations of the
successor company to issue or deliver, on the terms and conditions of the Plan,
the same Substitute Interests as were exchanged for Membership Interests or into
which Membership Interests were converted or changed in such transaction. Before
entering into any such transaction, the Company shall cause the successor
company to cause there to be reserved sufficient Substitute Interests so that
there will

                                       15
<PAGE>

be available for delivery upon exercise of all the Options then
outstanding, in lieu of the Membership Interests subject to such Options, such
Substitute Interests as would have been issued in respect of the Membership
Interests subject to such Options if all of such Membership Interests have been
outstanding at the time such transaction occurred. In such circumstances, the
outstanding Options will continue to vest and become exercisable in accordance
with the vesting and exercise schedule and other terms and conditions provided
by this Plan. Notwithstanding any other provision of this Plan, upon the
occurrence of such a transaction, if the Company does not continue in existence,
then its successor shall be deemed the "Company" for all purposes of this Plan
and the Company, before engaging in such a transaction, shall cause the
successor entity to assume all of the Company's obligations under this Plan and
the successor shall have all of the Company's rights and powers under this Plan.

     Other Extraordinary Transactions

     12.5. In the event of any change in the outstanding Units of Membership
Interests that are subject to Options granted under this Plan, whether as a
result of a merger, consolidation, recapitalization (including any split or
combination of Units), dividend or distribution of any equity interest, debt
instrument or security on such Units, exchange by the Company or any Affiliate
of any equity interest, debt instrument or security for such Units, or other
like change in the capital structure of the Company, unless the provisions of
paragraphs 12.2 or 12.4 or 12.6 hereof are applicable to such change, the Option
Committee shall make such adjustments to each outstanding Option as are, in its
good faith judgment, equitable to prevent any material diminution or enlargement
of the rights of the optionholder. Such adjustments may include, if determined
to be equitable by the Option Committee, the treatment of equity interests, debt
instrument or securities distributed or exchanged for Membership Interests as
Substitute Interests (as provided by paragraph 12.4 hereof) or an increase or
decrease in the exercise price of the Option, among other things. In addition,
in any such event the Option Committee may adjust the maximum number of Units of
Eligible Membership Interests as it considers equitable and consistent with the
purpose of this Plan.

     12.6. In the event of any extraordinary distribution of assets of the
Company in respect of Membership Interests that are subject to Options granted
under the Plan or like extraordinary change in the Company's capital structure,
unless the provisions of paragraphs 12.2 or 12.4 or 12.5 hereof are applicable
to such change, the Option Committee shall make such adjustments to each
outstanding Option as are, in its good faith judgment, equitable to prevent any
material diminution or 

                                       16
<PAGE>

enlargement of the rights of the optionholder; provided,
however, that no such adjustment need be made with respect to any Option that
was exercisable at the time of such extraordinary transaction and which the
optionholder had a fair opportunity to exercise such that, if he had done so,
the optionholder would have participated in respect of the Membership Interest
subject to the Option in such transaction. For purposes hereof, a distribution
in any period of six consecutive months of assets of the Company having a fair
market value (as determined in good faith by the Option Committee) of less than
10% of the Value of the Company at the time of the first distribution made
during such period shall not be considered an extraordinary distribution.

     13. RIGHT TO TERMINATE EMPLOYMENT

     The Plan shall not impose any obligation on the Company or any Subsidiary,
to continue the employment of or any consultancy with any Participant, and it
shall not impose any obligation on the part of any Participant to remain in the
employ of or as a consultant to the Company.

     14. SECURITIES LAW MATTERS

     14.1. Except as hereinafter provided, the Option Committee may require a
Participant, as a condition of exercise of any Option granted hereunder, to
execute and deliver to the Company a written statement, in form satisfactory to
the Option Committee, in which such Participant represents and warrants that the
Membership Interest is being acquired for such Participant's own account for
investment only and not with a view to the resale or distribution thereof. The
Participant, at the request of the Option Committee, may further be required as
a condition of exercise of any Option, to agree in writing that any subsequent
resale or distribution by the Participant of a Membership Interest acquired by
it pursuant to an Option shall be made only pursuant to either (i) a
Registration Statement on an appropriate form under the Securities Act, which
Registration Statement has become effective and is current with regard to the
Membership Interest being sold, or (ii) a specific exemption from the
registration requirements of the Securities Act, and that in claiming such
exemption the Participant shall, prior to any offer of sale or sale of such
Partner Interest, obtain a prior favorable written opinion of counsel, in form
and substance satisfactory to counsel for the Company, as to the application of
such exemption thereto. The requirements of this paragraph 14.1 shall not apply
to (i) issuances of Membership Interests to Participants pursuant to the
exercise of Options if the Membership Interests being issued are
contemporaneously being registered for

                                       17
<PAGE>

public offering and sale under the Securities Act or (ii) re-offerings of
Membership Interests by Participants who are considered affiliates of the
Company (as defined in Rule 405 or any successor rule or regulation promulgated
under the Securities Act) if the Membership Interests being re-offered are
registered under the Securities Act and a prospectus in respect thereof is
current.

     14.2. In the event the Company registers under the Securities Act
Membership Interests for public offering and sale and at such time any
Participant holds Membership Interests as a result of having exercised Options
and such Participant by reason of his relationship with the Company cannot
lawfully sell the Membership Interests owned by him publicly without
registration thereof under the Securities Act, the Company shall give notice of
said proposed registered public offering to such Participant and, if requested
by the Participant, use its reasonable best efforts to include such
Participant's Membership Interest in said registered public offering so as to
permit such Participant to publicly sell his Membership Interests publicly by
means thereof.

     15. WITHHOLDING TAXES

     The Company may require, as a condition to the exercise of an Option or as
a condition to effectuating a repurchase of an Option pursuant to Sections 9 or
12 hereof, that the Company be reimbursed in cash for any taxes required by any
government to be withheld or otherwise deducted and paid by the Company in
respect of the issuance or disposition pursuant to the Option of a Membership
Interest or the repurchase by the Company of the Option. In lieu thereof, the
Company or any Affiliate thereof which employs the Participant exercising the
Option shall have the right to withhold the amount of such taxes from any other
sums due or to become due from it to the Participant.

     16. USE OF PROCEEDS

     The cash proceeds of the sale of Membership Interests pursuant to the Plan
are to be added to the general funds of the Company and shall be used for its
general corporate purposes as the Management Committee shall determine.

                                       18
<PAGE>

     17. AMENDMENT OF THIS PLAN

     The Option Committee in its discretion may, from time to time, amend this
Plan in any respect and without the consent of any Participant, provided that no
amendment shall be made that will adversely affect the rights under any Option
granted before amendment of this Plan without the consent of the holder of such
Option.

     18. TERMINATION OR SUSPENSION OF THE PLAN

     The Management Committee may at any time suspend or terminate the Plan
except with respect to Options then outstanding. This Plan, unless sooner
terminated by action of the Management Committee, shall terminate at the close
of business on the later of the Grant Termination Date or the date all Options
outstanding have been exercised or have expired, provided that the provisions of
paragraph 14.2 of this Plan and the provisions of this Plan regarding
administration shall remain in effect indefinitely. Options may not be granted

                                          3

          (c)  INSTRUCTIONS REGARDING THE ESCROW ACCOUNTS.  Notwithstanding any
other provision hereof to the contrary, the Escrow Agent shall follow the
instructions of the Issuers with respect to the disposition of any and all
monies, instruments and other property deposited or accumulated in the Escrow
Accounts as directed by the Issuers unless and until the Escrow Agent shall have
received written instructions to the contrary from the Trustee ("Trustee
Instructions Notice"), in which case the Escrow Agent shall follow the Trustee
Instructions Notice.

          The Escrow Agent agrees, and is hereby authorized and directed by the
Issuers to pay to the Trustee upon its demand, following delivery to the Escrow
Agent of a Trustee Instructions Notice, all funds that may hereafter be
withdrawable or payable out of the Escrow Accounts, and the Escrow Agent will
not release to the Issuers, and the Issuers will not withdraw or attempt to
withdraw any funds or other property from the Escrow Accounts following delivery
of such Trustee Instructions Notice.  Following an Event of Default (as defined
in the Indenture) and delivery to the Escrow Agent of a Trustee Instructions
Notice, the Trustee is hereby authorized and fully empowered without further
authority from the Issuers to request the Escrow Agent to remit to the Trustee
any funds that may be due to the Issuers, and the Escrow Agent is hereby
authorized and directed to pay to the Trustee such sums as it shall so request
without the consent of the Issuers.

          The Escrow Agent, the Issuers and the Trustee agree that (i) the
Escrow Accounts are "securities accounts" within the meaning of Article 8 of the
UCC; (ii) the Escrow Agent is acting in the capacity of a "securities
intermediary" within the meaning of Article 8 of the UCC; (iii) all assets now
or hereafter comprising the Collateral and held in either of the Escrow Accounts
are "financial assets" within the meaning of Article 8 of the UCC; and (iv) any
Trustee Instructions Notice will be deemed to be an "entitlement order" within
the meaning of Article 8 of the UCC.  The Escrow Agent agrees that (x) it will
comply with all entitlement orders originated by the Trustee regarding the
disposition of any Collateral, without further consent by the Issuers, and (y)
it will not comply with any entitlement orders within the meaning of Article 8
of the UCC, except as expressly permitted or required by this Agreement.

          (d)  APPOINTMENT AS ATTORNEY-IN-FACT.  The Issuers hereby constitute
and appoint the Trustee their true, lawful and irrevocable attorney to demand,
receive and enforce payments and to give receipts, releases, satisfactions for,
and to sue for all receipts, releases, satisfactions for, and to sue for all
monies payable to the Issuers and this may be done following delivery to the
Escrow Agent of a Trustee Instructions Notice in the name of the Trustee with
the same force and effect as the Issuers could do had the Issuers not granted a
security interest in the Escrow Accounts to the Trustee pursuant to the Security
Agreement.  Any and all monies and payment which may be received by the Issuers
from the Escrow Accounts, to which the Trustee is entitled under and by reason
of such security interest, will be received by the Issuers as trustee for the
Trustee, and will be immediately delivered in kind to the Trustee without
commingling.  The Trustee agrees that, except upon the occurrence and during the
continuance of any Event of Default, it will forbear from exercising the power
of attorney or any rights granted to the Trustee pursuant to this paragraph.


                                          4

<PAGE>

          (e)  RIGHTS OF THE ISSUERS.  Nothing herein contained shall be
construed so as to prevent the Issuers from remaining the owners, subject to the
security interest of the Trustee under the Security Agreement, of the Escrow
Accounts.  Until the Trustee elects to the contrary and delivers a Trustee
Instructions Notice in writing to the Escrow Agent, subject to Sections 2(g) and
3 of this Agreement, the Issuers may make such additional transactions in the
Escrow Accounts and with respect to the securities and other instruments on
deposit therein as they shall elect.  In the event the Trustee does make such
election and does deliver such Trustee Instructions Notice to the Escrow Agent,
the Issuers shall not thereafter execute any transactions in the Escrow Accounts
or with respect to the securities or other instruments on deposit therein and
the Escrow Agent shall not accept for execution any such transactions without
the concurrence of the Trustee.

          Following delivery to the Escrow Agent of a Trustee Instructions
Notice, the Trustee shall be entitled without the consent or concurrence of, or
prior notice to, the Issuers, to direct the Escrow Agent to liquidate any or all
securities or other instruments held in the Escrow Accounts and to direct the
Escrow Agent to pay to the Trustee the credit balance as shall exist in the
Escrow Accounts after such liquidation and after the payment to the Escrow Agent
of all the indebtedness of the Issuers to the Escrow Agent in connection with
transactions in the Escrow Accounts.

          Any sums paid by the Escrow Agent from the Escrow Accounts to the
Trustee under the Security Agreement shall be applied by the Trustee to the
payment of the Obligations, to the extent of the Obligations, as such term is
defined in the Security Agreement.  The receipt or receipts of the Trustee for
such funds paid to it by the Escrow Agent after delivery to the Escrow Agent of
a Trustee Instructions Notice shall as to the Escrow Agent operate as the
receipt of the Issuers as fully and as completely as if funds had been paid to
the Issuers in person and receipted for by the Issuers.

          (f)  ESCROW AGENT COMPENSATION.

               (i)  Escrow Agent shall be compensated pursuant to a separate
     agreement between the Issuers and Escrow Agent.

               (ii) Escrow Agent shall be entitled to disburse from the
     Construction Escrow Account all amounts due to Escrow Agent as compensation
     for services to be performed by Escrow Agent under this Agreement (as
     determined by agreement with the Issuers pursuant to this Section
     2(c)(ii)). The final payment pursuant to this Section 2(c)(ii) shall be
     prorated if for a partial month.

          The Escrow Agent waives and agrees not to assert, claim or endeavor to
exercise, and by executing this Agreement bars and estops itself from asserting,
claiming or exercising any right of setoff, banker's lien, security interest or
other purported form of claim with respect to the Escrow Accounts and funds from
time to time therein.  The Escrow Agent shall have no rights in the Escrow
Accounts or the funds therein until the Trustee notifies the Escrow Agent that
all Obligations (as defined in the Security Agreement) have been paid in full
and the Indenture is no longer in effect.  To 


                                          5

<PAGE>

the extent the Escrow Agent may ever have any such rights, the Escrow Agent
hereby expressly subordinates all such rights to all rights of the Trustee.

          (g)  INVESTMENT OF FUNDS IN ESCROW ACCOUNTS. Funds deposited in the
Escrow Accounts shall be invested and reinvested by the Escrow Agent upon the
following terms and conditions:

               (i)   ACCEPTABLE INVESTMENTS. Funds deposited in the Escrow
Accounts shall be invested, and all interest earned thereon or other
distributions or amounts paid with respect thereto may be reinvested, as
directed in writing by the Issuers in Temporary Cash Investments which the
Issuers reasonably determine at such time will produce without reinvestment of
the funds so deposited or reinvestment of income produced by such Temporary Cash
Investments and without further deposit by the Issuers, funds sufficient to
cover, (x) in the case of the Interest Escrow Account, all interest due on the
outstanding Notes, as such interest becomes due, for the Interest Payment Dates
occurring on November 1, 1998 and May 1, 1999 and (y) in the case of the
Construction Escrow Account, for such Construction Expenses (as defined below)
as such come due.  The Escrow Agent shall have no responsibility for determining
whether funds held in the Escrow Accounts shall have been invested in such a
manner so as to comply with the requirements of this clause (i). 

               (ii)  SECURITY INTEREST IN INVESTMENTS.  No investment of funds
in the Escrow Accounts shall be made unless, if requested by the Escrow Agent,
the Issuers have certified to Escrow Agent upon advice of legal counsel that,
upon such investment, the Trustee will have a perfected security interest in the
applicable investment (such advice of legal counsel relating solely to the
manner of perfecting a security interest in a particular type of investment, but
not to whether such perfection has been achieved in the instance). A certificate
as to a class of investments need not be issued with respect to individual
investments in securities in that class if the certificate applicable to the
class remains accurate with respect to such individual investments, which
continued accuracy the Escrow Agent may conclusively assume. When and if the
Indenture is qualified under the Trust Indenture Act of 1939, as amended (the
"TIA"), on such date and on each anniversary of such date until the date upon
which the balance of the Available Funds shall have been reduced to zero, each
of the Trustee and the Escrow Agent shall receive an opinion of counsel to the
Issuers, dated each such date as applicable, which opinion shall meet the
requirements of Section 314(b) of the TIA.

               (iii) INTEREST AND DIVIDENDS. All interest earned and dividends
paid on funds invested in such Temporary Cash Investments shall be deposited in
the Escrow Accounts for the exclusive benefit of the Trustee for the ratable
benefit of the holders of the Notes and shall be reinvested in accordance with
the terms hereof at the Issuers' written instruction and subject to disbursement
as provided herein. 

          (h)  LIMITATION ON ESCROW AGENT'S RESPONSIBILITIES. 


                                          6

<PAGE>

               (i)   Escrow Agent's duties and responsibilities shall be limited
to those expressly set forth in this Agreement and are purely ministerial in
nature. The Escrow Agent shall not be called upon to advise any party as to
selling or retaining, or taking or refraining from taking any action with
respect to, any securities or other property deposited hereunder. Escrow Agent
shall not be subject to, or obligated to recognize, any other agreement to which
the Issuers, the Trustee, or either of them may be a party. References in this
Agreement to any such agreement are for identification and definitional purposes
only.

               (ii)  Escrow Agent shall have no obligation with respect to the
Escrow Accounts other than to follow faithfully instructions contained in this
Agreement or delivered to Escrow Agent in accordance with this Agreement. Escrow
Agent may rely and act upon any written notice, instruction, direction, request,
waiver, consent, receipt, or other paper or document, including any Trustee
Instructions Notice ("Instructions") that it believes in good faith to be
genuine and what it purports to be. Escrow Agent shall be subject to no
liability with respect to the form, execution, or validity of any such
Instruction. The Escrow Agent shall not be liable for verifying the accuracy of
any certifications made by the Issuers in an Officers' Certificate delivered
under Section 3.

               (iii) Escrow Agent shall not be liable for any error of judgment,
or for any act done or step taken or omitted by it in good faith, or for any
mistake of fact or law, or for doing anything which, in good faith, it may do or
refrain from doing in connection with the Escrow Accounts, except in each case
in the event of Escrow Agent's gross negligence or wilful misconduct.

          (i)  SUBSTITUTION OF ESCROW AGENT.

               (i)   The Issuers shall have the right to cause Escrow Agent to
be relieved of its duties hereunder and to select a substitute escrow agent to
serve hereunder (provided such substitute escrow agent is an Acceptable
Replacement Escrow Agent), upon the expiration of 30 days following delivery of
written notice of substitution to Escrow Agent and the Trustee. Upon selection
of such substitute escrow agent, such substitute escrow agent and the parties
hereto other than the substituted escrow agent shall enter into an agreement
substantially identical to this Agreement and, thereafter, Escrow Agent shall be
relieved of its duties and obligations to perform hereunder, except that Escrow
Agent shall transfer to the substitute escrow agent upon request therefor all
assets held in the Escrow Account and copies of all books, records, plans and
other documents in Escrow Agent's possession relating to such assets or this
Agreement. 

               (ii)  Escrow Agent, or any substitute escrow agent, may at any
time resign and be discharged of its duties and obligations under this Agreement
by giving at least 30 days' notice to the Issuers and the Trustee. The Issuers
shall appoint a substitute escrow agent (provided such substitute escrow agent
shall be an Acceptable Replacement Escrow Agent) within such 30 day period and
such substitute escrow agent and the parties hereto 


                                          7

<PAGE>

(other than the resigning Escrow Agent) shall enter into an agreement
substantially identical to this Agreement.

               (iii) If the Issuers fail to appoint a substitute escrow agent as
     required under paragraph (ii) above, Escrow Agent shall deliver all assets
     held in the Escrow Accounts and copies of all books, records, plans and
     other documents in the Escrow Agent's possession relating to such assets or
     this Agreement to a substitute escrow agent (provided such substitute
     escrow agent shall be an Acceptable Replacement Escrow Agent) of either its
     choosing or as appointed by a court upon application therefor.

               (iv)  Escrow Agent shall be discharged from any further duties
     under this Agreement upon its transfer of the assets held in the Escrow
     Accounts and copies of all books, records, plans and other documents in the
     Escrow Agent's possession relating to such assets or this Agreement to an
     Acceptable Replacement Escrow Agent.

          (j)  INTEREST ESCROW ACCOUNT STATEMENT. At least 30 days prior to each
Interest Payment Date, the Escrow Agent shall deliver to the Issuers and the
Trustee a statement setting forth with reasonable particularity the Collateral
then held by the Escrow Agent, and the manner in which such funds are invested
(the "Interest Escrow Account Statement"). The books and records of the Escrow
Agent with respect to the Interest Escrow Account shall be available upon
written request by the Trustee and the Issuers or their respective
representatives. The parties hereto irrevocably instruct Escrow Agent that on
the first date upon which the balance in the Interest Escrow Account (including
the holdings of all Temporary Cash Investments) is reduced to zero, Escrow Agent
shall deliver to the Issuers and to the Trustee a notice that the balance in the
Interest Escrow Account has been reduced to zero.

          (k)  CONSTRUCTION ESCROW ACCOUNT STATEMENT. At the first Business Day
of each month, the Escrow Agent shall deliver to the Issuers and the Trustee a
statement setting forth with reasonable particularity the Collateral then held
by the Escrow Agent in the Construction Escrow Account, and the manner in which
such funds are invested (the "Construction Escrow Account Statement"). The books
and records of the Escrow Agent with respect to the Construction Escrow Account
shall be available upon written request by the Trustee and the Issuers or their
respective representatives. The parties hereto irrevocably instruct Escrow Agent
that on the first date upon which the balance in the Construction Escrow Account
(including the holdings of all Temporary Cash Investments) is reduced to zero,
Escrow Agent shall deliver to the Issuers and to the Trustee a notice that the

     construction of any of the provisions of this Agreement or any of Escrow

     liability in acting in good faith in accordance with the advice of such
     counsel. The fees and expenses for consultation with a single firm of

changes to such a certificate. Escrow Agent may rely on the accuracy and
completeness of any such certificate unless and until it has received an
acceptable replacement certificate. All certificates provided under this Section
2(m) shall be executed by the applicable party's corporate secretary or
assistant secretary or, if the party does not have a corporate secretary or

     3.   DISBURSEMENTS.

          (a)  The Escrow Agent will make payments from the Interest Escrow
Account as follows: (i) on each of the first two Interest Payment Dates, an
amount equal to the installment then due, to be remitted to the Paying Agent for
the Notes, and (ii) in the event the Issuers are required to repurchase Notes
pursuant to the Indenture, on the repurchase date, an amount equal to the
aggregate amount of accrued interest paid to the holders whose Notes were
repurchased.  A failure to pay interest on the Notes in a timely manner through
the first two scheduled Interest Payment Dates will constitute an immediate
Event of Default under the Indenture, with no grace or cure period.

          (b)  The Escrow Agent will make payments from the Construction Escrow
Account as follows: On the first Business Day of each calendar month beginning
after the date that the Issuers shall have paid an aggregate of at least $50
million for the following:  (x) installment payments to AMFELS of the amount
specified under the related Construction Contract as the total purchase price to
be paid to AMFELS of such Rig (the "Purchase Price") PLUS (y) payments for OFE
PLUS (z) Construction Overhead (or, in the case of the first calendar month in
which the Issuers shall have so paid such amount, on any Business Day thereafter
during such calendar month), an amount equal to the sum of (i) each installment
payment of the Purchase Price of the Rigs required to be paid on each Rig
Purchase Installment Date in such calendar month pursuant to the Construction
Contracts, as adjusted for any change orders provided pursuant to the
Construction Contracts, (ii) the aggregate amount estimated in good faith by the
Issuers to be required in such calendar month to pay for the purchase price of
OFE, and Construction Overhead, up to an aggregate amount not to exceed $55.0
million and (iii) with respect to any calendar month beginning on or after the
Delivery Date of the first Rig to be completed (the "First Completed Rig") and
prior to the Delivery Date of 


                                          9

<PAGE>

the second Rig to be completed (the "Second Delivery Date"), an aggregate amount
estimated by the Issuers to be required to fund the working capital in such
calendar month for the operation of the First Completed Rig, not to exceed $10.0
million, ((i) through (iii) above collectively referred to as "Construction
Expenses");  PROVIDED, HOWEVER, that at least three Business Days prior thereto,
the Issuers shall have delivered to the Trustee and the Escrow Agent an
Officers' Certificate setting forth in reasonable detail (i) the amount,
category and purpose of each requested payment, (ii) in the case of any payments
other than installment payments of the Purchase Prices of the Rigs, the amount
available for payment, after giving effect to all previous payments, and (iii) a
reconciliation of payments made from the Construction Escrow Account to actual
expenditures, which reconciliation shall be made on a cumulative basis through
the end of the second calendar month proceeding the month in which such
Officers' Certificate is delivered. Notwithstanding the foregoing, in the event
the Issuers are required to repurchase Notes upon a Contract Termination, the
Escrow Agent will make a payment on the repurchase date, in an amount equal to
the Allocated Portion of the remaining funds in the Construction Escrow Account,
to be deposited with the Paying Agent for application to pay the purchase price
of Notes accepted for repurchase.  Pending application of the Collateral so
released from the Construction Escrow Account pursuant to this Agreement, such
Collateral shall be invested in Temporary Cash Investments.  

          (c)  Upon receipt by the Escrow Agent of an Officers' Certificate of
the Issuers that the Issuers have made the first two scheduled interest payments
on the Notes, the Collateral in the Interest Escrow Account shall be released
from the Interest Escrow Account to the order of the Issuers.  Upon receipt by
the Escrow Agent of an Officers' Certificate of the Issuers that the Issuers
have made the final installment of the Purchase Price for each of the Rigs in
accordance with the related Construction Contracts, the Collateral in the
Construction Escrow Account will be released from the Construction Escrow
Account  to the order of the Issuers.  Upon release of all the Collateral from
the Escrow Accounts, the Notes will be unsecured.

          (d)  The Issuers and the Trustee each shall provide a certificate to
Escrow Agent as to the incumbency and signatures of those individuals authorized
to provide from time to time instructions relating to the Escrow Accounts or to
execute documents to be provided to Escrow Agent. The Issuers and the Trustee
also shall promptly notify the Escrow Agent of any changes to such a
certificate. Escrow Agent may rely on the accuracy and completeness of any such
certificate unless and until it has received an acceptable replacement
certificate. All certificates provided under this Section 3(d) shall be executed
by the applicable party's corporate secretary or assistant secretary or, if the
party does not have a corporate secretary or assistant secretary, by a
comparable officer.

          (e)  RETIRED NOTES, ETC. In the event that a portion of the Notes has
been retired by the Issuers and submitted to the Trustee for cancellation or, if
additional cash has been deposited into the Interest Escrow Account pursuant to
Section 3(g) below and, thereafter, the Registration Default (as defined in the
Registration Rights Agreement is cured, and there is no Default or Event of
Default under the Indenture, funds representing the lesser of (i) the excess of
the then Available Funds over the amount sufficient to pay interest through and
including May 1, 1999 on the Notes not so retired and (ii) the interest payments
which have not previously been made on such retired Notes 


                                          10

for each Interest Payment Date through the Interest Payment Date to occur on May
1, 1999 shall, upon written request of the Trustee to the Escrow Agent.  The
Trustee shall provide such notice to the Escrow Agent (A) upon receipt of notice
of similar effect from the Issuers (which notice from the Issuers shall be
accompanied by an agreed upon procedures report by a nationally recognized
independent public accounting or investment banking firm which sets forth the
calculations to determine such lesser amount and recalculates the amounts
remaining in the Interest Escrow Account as sufficient to produce without
reinvestment of the remaining funds or reinvestment of income produced by the
remaining Temporary Cash Investments and without further deposit by the Issuers,
funds sufficient to cover all interest due on the remaining outstanding Notes,
as such interest becomes due, for the Interest Payment Dates occurring on
November 1, 1998 and May 1, 1999) and (B) upon compliance with the release of
collateral provisions of the TIA to the extent required by the Indenture.

          (f)  EXCESS AMOUNTS. At such time as all interest due on the Notes
through and including May 1, 1999 has been paid to the Holders thereof pursuant
to the Indenture and in accordance herewith, the Escrow Agent shall disburse all
remaining funds in the Interest Escrow Account to the Issuers. The Trustee shall
provide notice to the Escrow Agent to such effect upon receipt of notice from
the Issuers after the time all interest due on the Notes through and including
May 1, 1999 has been paid to the Holders.

          (g)  ADDITIONAL AMOUNTS.  In the event the Issuers become obligated to
pay Additional Interest (as defined in the Registration Rights Agreement) under
the circumstances described in Section 11.1 of the Indenture, the Issuers shall
deposit into the Interest Escrow Account additional cash pursuant to Section
11.1 of the Indenture.

     4.   ESCROW AGENT. The Escrow Agent's responsibility and liability under
this Agreement shall be limited as follows: (a) the Escrow Agent does not
represent, warrant or guaranty to the holders of the Notes from time to time the
performance of the Issuers or the Trustee; (b) the Escrow Agent shall have no
responsibility to the Issuers or the holders of the Notes or the Trustee from
time to time as a consequence of performance or nonperformance by the Escrow
Agent hereunder, except for any gross negligence or wilful misconduct of the
Escrow Agent; (c) the Issuers shall remain solely responsible for all aspects of
the Issuers' business and conduct; and (d) the Escrow Agent is not obligated to
supervise, inspect or inform the Issuers or any third party of any matter
referred to above.

     No implied covenants or obligations shall be inferred from this Agreement
against the Escrow Agent, nor shall the Escrow Agent be bound by the provisions
of any agreement beyond the specific terms hereof. Specifically and without
limiting the foregoing, the Escrow Agent shall in no event have any liability in
connection with its investment, reinvestment or liquidation, in good faith and
in accordance with the terms hereof, of any funds or Temporary Cash Investments
held by it hereunder, including, without limitation any liability for any delay
not resulting from gross negligence or wilful misconduct in such investment,
reinvestment or liquidation, or for any loss of principal or income incident to
any such delay.

     The Escrow Agent shall be entitled to rely upon any judicial order or
judgment, upon any written opinion of counsel or upon any certification,
instruction, notice, or other writing delivered to it by the Issuers or the
Trustee in compliance with the provisions of this Agreement without being
required to determine the authenticity or the correctness of any fact stated
therein or the propriety or validity of service thereof. The Escrow Agent may
act in reliance upon any instrument comporting with the provisions of this
Agreement or signature believed by it to be genuine and may assume that any
person purporting to give notice or receipt or advice or make any statement or
execute any document in connection with the provisions hereof has been duly
authorized to do so.

     The Escrow Agent may act pursuant to the advice of counsel chosen by it
with respect to any matter relating to this Agreement and (subject to clause (b)

     The Escrow Agent shall not be called upon to advise any party as to selling
or retaining, or taking or refraining from taking any action with respect to,
any securities or other property deposited hereunder.

respect to any funds or property deposited hereunder, the Escrow Agent shall be
entitled to refuse to comply with any and all claims, demands or instructions
with respect to such funds or property, and the Escrow Agent shall not be or
become liable for its failure or refusal to comply with conflicting claims,
demands or instructions. The Escrow Agent shall be entitled to refuse to act
until either any conflicting or adverse claims or demands shall have been
finally determined by a court of competent jurisdiction or settled by agreement
between the conflicting claimants as evidenced in a writing, satisfactory to the
Escrow Agent, or the Escrow Agent shall have received security or an indemnity
satisfactory to the Escrow Agent sufficient to save the Escrow Agent harmless
from and against any and all loss, liability or expense which the Escrow Agent
may incur by reason of its acting. The Escrow Agent may in addition elect in its
sole option to commence an interpleader action or seek other judicial relief or
orders as the Escrow Agent may deem necessary.

     No provision of this Agreement shall require the Escrow Agent to expend or
risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder.

     5.   INDEMNITY. Each Issuer shall jointly and severally indemnify, hold
harmless and defend Escrow Agent and the Trustee, and their respective
directors, officers, agents and employees, from and against any and all claims,
actions, obligations, liabilities and expenses, including defense costs,
investigative fees and costs, legal fees, and claims for damages, arising from
Escrow Agent's and the Trustee's respective performance under this Agreement,
except to the extent that such liability, expense or claim is directly
attributable to the gross negligence or wilful misconduct of such indemnified
person. In connection with any claim, action, obligation, liability or expense
for which indemnification is sought by the Escrow Agent hereunder, the Escrow
Agent shall be entitled to recover its costs as incurred from funds available in
the Construction Escrow Account.

     6.   INSTRUCTIONS TO ESCROW AGENT.

          (a)  Each Issuer and the Trustee hereby irrevocably instruct the

Escrow Agent of any nature whatsoever now or hereafter existing, in favor of
anyone other than the Trustee; (ii) promptly notify the Trustee if Escrow Agent

interest upon any portion of the Collateral (other than any claim which Escrow
Agent may have against the Construction Escrow Account for unpaid fees and

to the Trustee and transfer title to all Temporary Cash Investments held by

necessary action within its power to preserve and protect the security interest
created hereby as a lien and encumbrance upon the Collateral. 

          (d)  Each Issuer hereby appoints the Trustee as its attorney-in-fact

hereto to do, except that the Trustee shall not direct the investment of any
monies on deposit in the Escrow Accounts, and the Trustee may exercise such
rights as each Issuer may exercise with respect to the Collateral and take any
action in each Issuer's name to protect the Trustee's security interest
hereunder.

obligations of each Issuer under Section 5 of this Agreement shall survive
termination of this Agreement or the resignation or removal of the Escrow Agent;
provided, further, however, that until such tenth day, the Issuers will cause
this Agreement (or any permitted successor agreement) to remain in effect and

               (b) Anything herein contained to the contrary notwithstanding, 
each Grantor shall remain liable under the Assigned Agreement, to perform all 
of the obligations undertaken by it thereunder, all in accordance with and 
pursuant to the terms and provisions thereof, and the Collateral Agent shall

connection therewith and to file any claims or take any action or institute 
any proceedings in connection therewith which the Collateral Agent may deem

written notice of such intent to such Grantor and to the other parties to the 
Assigned Agreement. Any curing by the Collateral Agent of such Grantor's 
default under the Assigned Agreement shall not be construed as an assumption 
by the Collateral Agent of any obligations, covenants or agreements of such 
Grantor under such Assigned Agreement, and the Collateral Agent shall not 
incur any liability to such Grantor or any other Person as a result of any 
actions undertaken by the Collateral Agent in curing or attempting to cure 
any such default. This Agreement shall not be deemed to release or to affect 
in any way the obligations of such Grantor under the Assigned Agreement.

Grantor owing to the holders of the Notes under the Notes and the Indenture 
(such obligations being herein called the "Obligations").

and as defined in the Indenture, whatever the reason for such Event of 
Default and whether it shall be voluntary or involuntary or be effected by 
operation of law or pursuant to any judgment, decree or order of any court or 
any order, rule or regulation of any administrative or governmental body, 
shall constitute an Event of Default hereunder.

         5. Remedies.

               (a) If any Event of Default has occurred and is continuing, 
the Collateral Agent may, (i) apply the Collateral to any Obligations due and 
payable, (ii) proceed to protect and enforce the rights vested in it by this 
Agreement, including the right to cause all revenues hereby pledged as 
security and all other moneys pledged hereunder to be paid directly to it, 
and to enforce its rights hereunder to such payments and all other rights 
hereunder by such appropriate judicial proceedings as it shall deem most 
effective to protect and enforce any of such rights, either at law or in 
equity or otherwise, whether for specific enforcement of any covenant or 
agreement contained in the Assigned Agreement, or in aid of the exercise of 
any power therein or herein granted, or for any foreclosure hereunder and 
sale under a judgment or decree in any judicial proceeding, or to enforce any 
other legal or equitable right vested in it by this Agreement or by law; 
(iii) cause any action at law or suit in equity or other proceeding to be 
instituted and prosecuted to collect or enforce any Obligations or rights 
included in the Collateral, or to foreclose or enforce any other agreement or

or secured, subject in each case to the provisions and requirements thereof;

in one or more sales or transactions, at such prices as the Collateral Agent 
may deem best, and for cash or on credit or for future delivery, without 
assumption of any credit risk, at any broker's board or at public or private 
sale, without demand of performance or notice of intention to sell or of time 
or place of sale (except such notice as is required by applicable statute, 
rule or regulation and cannot be waived), it being agreed that the Collateral 
Agent may be a purchaser on behalf of the holders of Notes at any such sale 
and that the Collateral Agent or anyone else who may be the purchaser of any 
or all of the Collateral so sold shall thereafter hold the same absolutely, 
free from any claim or right of whatsoever kind, including any equity of 
redemption, of either Grantor, any such demand, notice or right and equity 
being hereby expressly waived and released to the extent permitted by law; 
(v) incur expenses, including attorneys' fees, consultants' fees, and other 
costs appropriate to the exercise of any right or power under this Agreement; 
(vi) perform any obligation of either Grantor hereunder, and make payments, 
purchase, contest or compromise any Lien, and pay taxes and expenses, 
without, however, any obligation so to do; (vii) take possession of the 
Collateral, control and manage the Collateral, collect all income from the 
Collateral and apply the same to reimburse the Trustee, Collateral Agent and 
the holders of Notes for any cost or expenses incurred hereunder or under the 
Indenture and to the payment or performance of each Grantor's obligations 
hereunder or under the Indenture, and apply the balance to the Notes as 
provided in the Indenture and any remaining excess balance to whomsoever is 
legally entitled thereto; (viii) secure the appointment of a receiver of the 
assets of either such Grantor or any part thereof and/or the Collateral or 
any party thereof; or (ix) exercise any other or additional rights or 
remedies granted to a secured party under the Uniform Commercial Code. If, 
pursuant to applicable law, rule or regulation prior notice of any such 
action is required to be given to either such Grantor, each such Grantor 
hereby acknowledges that the minimum time required by such applicable law, 
rule or regulation or if no minimum is specified, ten (10) Business Days, 
shall be deemed a reasonable notice period.

               (b) All costs and expenses (including reasonable attorneys' 
fees and expenses) incurred by the Collateral Agent in connection with any 
such suit or proceeding, or in connection with the performance by the 
Collateral Agent of any of such Grantor's agreements pursuant to any exercise 
of its rights or remedies hereunder, including the Assigned Agreement 
pursuant to the terms of this Agreement, together with interest thereon (to 
the extent permitted by law) computed at a rate per annum equal to the 
interest rate on the Notes from the date on which such costs or expenses are 
incurred to the date of payment thereof, shall constitute additional 
indebtedness secured by this Agreement and shall be paid by such Grantor to 
the Collateral Agent on behalf of the holders of Notes on demand.

         6. Remedies Cumulative; Delay Not Waiver.

               (a) No right, power or remedy herein conferred upon or 
reserved to the Collateral Agent is intended to be exclusive of any other 
right, power or remedy, and every such right, power and remedy shall, to the 
extent permitted by law, be cumulative and in addition to every other right, 
power and remedy given hereunder or now or hereafter existing at law or in 
equity or otherwise. The assertion or employment of any right or remedy 
hereunder, or otherwise, shall not prevent the

                                        4
<PAGE>

concurrent assertion or employment of any other appropriate right or remedy. 
Resort to any or all security now or hereafter held by the Collateral Agent, 
may be taken concurrently or successively and in one or several consolidated 
or independent judicial actions or lawfully taken nonjudicial proceedings, or 
both.

               (b) No delay or omission of the Collateral Agent to exercise 
any right or power accruing upon the occurrence and during the continuance of 
any Event of Default as aforesaid shall impair any such right or power or 
shall be construed to be a waiver of any such Event of Default or an 
acquiescence therein; and every power and remedy given by this Agreement may 
be exercised from time to time, and as often as shall be deemed expedient, by 
the Collateral Agent.

         7. Covenants. Each Grantor, jointly and severally, covenants as 
follows:

               (a) The Grantors shall not, and shall not permit any Affiliate 
to, take or knowingly omit to take, any action which action or omission might

respect to the Collateral for the benefit of the Collateral Agent, the 
Trustee and the holders of the Notes, and the Grantors shall not, and shall 
not permit any Affiliate to, grant to any Person other than the Collateral 
Agent, for the benefit of the Collateral Agent, the Trustee and the holders 
of the Notes, any interest whatsoever in any of the Collateral. Grantors

may deem necessary.

               (c) Grantors shall not modify, amend, terminate, waive or 
supplement any provision of the Assigned Agreement if any such modification, 
amendment, termination, waiver or supplement would adversely affect the 
interest of the Collateral Agent on behalf of the holders of the Notes in a 
degree greater than the manner in which it adversely affects Grantor.

               (d) Grantors shall pay, before the imposition of any fine, 
penalty, interest or cost attached thereto, all taxes, assessments and other 
governmental or non-governmental charges or levies now or hereafter assessed

Indenture, permit to remain unpaid or any charge being contested in good

limited liability company (the "Company"), and WILLIAM E. CHILES (the
"Executive").

     The Company desires to employ the Executive and the Executive desires to

Agreement.

     Accordingly, the parties agree as follows:
     
     1.   Employment, Duties and Acceptance.

          1.1  Employment by the Company and Duties.  The Company hereby agrees
to employ the Executive for a term commencing on the Effective Date and expiring
at the end of the day on the third anniversary of the Effective Date (such date,
or later date to which this Agreement is extended in accordance with the terms
hereof, the "Termination Date"), unless earlier terminated as provided in
Section 4 or unless extended as provided herein (the "Term"). The Term shall be
automatically extended commencing on the Termination Date and on each
Termination Date thereafter (each such date being a "Renewal Date"), so as to
terminate one (1) year from such Renewal Date, unless and until (i) at least
ninety (90) days prior to a Renewal Date either party hereto gives written
notice to the other that the Term should not be further extended, in which event
the Termination Date shall be the Renewal Date following such notice, or (ii)
less than ninety (90) days prior to a Renewal Date but before the Renewal Date
either party hereto gives written notice to the other that the Term should not
be further extended, in which event the Termination Date shall be the date
ninety (90) days after such written notice is given. If no such written notice
is given by either party prior to the Renewal Date, the Term shall be
automatically extended for another year from such Renewal Date, as provided in
the foregoing sentence. During the Term, the Executive shall serve in the
capacity of President and Chief Executive Officer of the Company, and shall also
serve in those offices and directorships of subsidiaries of the Company. or

During the Term, the Executive shall devote all reasonable efforts and
substantially all of his business time and services to the Company, subject to
the direction of the Management Committee of the Company (the "Committee"). The
Executive shall not engage in any other business activities except for passive
investments in corporations or partnerships not engaged in the Company Business
(as hereinafter defined) to the extent permitted by Section 3 1.1.


<PAGE>

          1.2  Acceptance of Employment by the Executive.  The Executive hereby
accepts such employment and shall render the services and perform the duties
described above.

     2.   Compensation and Other Benefits.

          2.1  Annual Salary.  The Company shall pay to the Executive an annual
salary at a rate of not less than two hundred thousand dollars ($200,000) per
year (the "Annual Salary"), subject to review and adjustment by the Committee
annually in accordance with industry standards, taking into account the
Executive's performance, the Company's scope of operations, industry conditions
and the overall performance of the Company within the industry. In no event
shall the Executive's Annual Salary be reduced to less than $200,000 per year
without his prior written consent. The Executive hereby expressly acknowledges
that the preceding two sentences shall not be construed as requiring the Company
or the Committee to make any annual increases in the Annual Salary. The Annual
Salary shall be payable in accordance with the payroll policies of the Company
as from time to time in effect, but in no event less frequently than once each
month, less such deductions as shall be required to be withheld by applicable
law and regulations.

          2.2  Bonuses. The Executive shall receive an incentive bonus, if
earned, with respect to fiscal years ending during the Term hereof (the
"Incentive Bonus"). The amount of the Incentive Bonus for the fiscal year ending
December 31, 1997 shall be determined by the Committee, in its sole discretion. 
The criteria for determining the amount of the Incentive Bonus for each fiscal
year thereafter shall be set forth in a formalized plan which is prepared by the
Committee and approved by the Compensation Committee of the Committee, if any.
The Committee shall use reasonable guidelines for establishing such criteria
based upon the performance of the Executive, including, without limitation, the
extent to which the Company achieves its business plan.

          2.3  Vacation Policy.  The Executive shall be entitled to a paid
vacation of four weeks during each year of the Term.

          2.4  Participation in Employee Benefit Plans. The Company agrees to
permit the Executive during the Term, if and to the extent eligible, to
participate in the group life, hospitalization and disability insurance plans,
health program, pension plan, any similar benefit plan or other so called
"fringe benefits" of the Company (collectively, "Benefits") which may be
available to other executives and employees of the Company on terms no less
favorable to the Executive than the terms offered to such other executives and
employees, to the extent such Benefits are offered by the Company. Provided the
Executive is insurable at standard rates (i) the Company agrees to use its best
efforts to obtain immediate coverage for the Executive upon 

                                          2
<PAGE>

employees without premium surcharge and without exclusions for disclosed 
preexisting conditions, and (ii) the Company shall increase the coverage

one million two hundred thousand dollars), and shall pay all premiums under 
such policy (or policies) during the Term.  During the Term, the Company also 
shall provide disability insurance for the Executive, which shall provide for 
payments based on 60% of the Annual Salary paid to the Executive for the 
prior fiscal year upon his disability; provided, however, that maximum amount 
the Company shall pay for such disability insurance shall be five thousand 
dollars per year. If such disability insurance premium exceeds five thousand 
dollars per year, the Executive may elect to pay the amount in excess of five 
thousand dollars per year in order to obtain such disability insurance. If 
the Executive does not elect to pay any such excess, the Company's obligation 
shall be limited to providing the maximum amount of disability insurance that 
may be obtained for five thousand dollars per year in payments. The Executive 
shall cooperate with the Company in applying for such coverage, including 
submitting to a physical exam and providing all relevant health and personal 
data.

          2.5  General Business Expenses.  The Company shall pay or reimburse
the Executive for all expenses reasonably and necessarily incurred by the
Executive during the Term in the performance of the Executive's services under
this Agreement. Such payment shall be made upon presentation of such
documentation as the Company customarily requires of its senior executive
employees prior to making such payments or reimbursements.

          2.6  Club Dues.  During the Term, the Company shall pay the Executive
an allowance of eight hundred dollars ($800.00) per month, which the Executive
shall apply to the cost associated with country club dues and expenses at the
Houston Country Club and the Houstonian, or any comparable clubs or
organizations, so long as the Executive is a member of such club or clubs.

     3.    Non-Competition Confidentiality and Company Property.

          3.1  Covenant Against Competition.  The  Executive acknowledges that
(i) the Company is currently engaged in the business of constructing, owning,

<PAGE>

offshore (the "Company Business") and (ii) the agreements and covenants 
contained in this Section 3 are essential to protect the business and 
goodwill of the Company. The Executive further acknowledges that the 
agreements and covenants contained in this Section 3 are being given to 
induce SEACOR Offshore Rigs Inc. to invest $35,000,000 in the Company. 
Accordingly, the Executive covenants and agrees as follows:

               3.1.1     Non-Compete. As an independent covenant, and in order
to enforce the provision of Section 3.1.2 hereof and the other provisions of

any offshore drilling business of any customer of the Company or its
subsidiaries; (iii) enter the employ of, or render any other services to, any
person engaged in the Company Business except as permitted hereunder; or (iii)
become interested in any such person in any capacity, including, without
limitation, as an individual, partner, shareholder, lender, officer, member,
manager, director, principal, agent or trustee except as permitted hereunder;
provided. however, that the Executive may own, directly or indirectly, solely as
an investment, securities of any person traded on any national securities
exchange or listed on the National Association of Securities Dealers Automated
Quotation System if the Executive is not a controlling person of, or a member of
a group which controls, such person and the Executive does not, directly or
indirectly, own 5% or more of any class of equity securities, or securities
convertible into or exercisable or exchangeable for 5% or more of any class of
equity securities, of such person. As used in this Agreement, the "Restricted
Period" shall mean a period commencing on the date hereof and continuing until
the end of the Term and for such additional period thereafter, if any, during
which the Company is obligated to pay the Severance Payments (as hereinafter
defined), and is making such payments, to the Executive as provided in Section
4.3 hereof.

               3.1.2     Property of the Company. All memoranda, notes, lists,
records, engineering drawings, technical specifications and related documents
and other documents or papers (and all copies thereof) relating to the Company
or its subsidiaries, including such items stored in computer memories, computer
disks, microfiche or by any other means, made or compiled by or on behalf of the
Executive during the Restricted Period, or made available to the Executive
during the Restricted Period relating to the Company, its affiliates or its
subsidiaries or any entity which may hereafter become an affiliate or subsidiary
thereof, shall be the property of the Company, and shall be delivered, along
with any copies thereof, to the Company promptly upon the termination of the
Executive's employment with the Company for any reason whatsoever or at any
other time upon request; provided, however, that the Executive's address books,
diaries, chronological correspondence files, rolodex files and 

                                        4

be deemed to be property of the Executive.

               3.1.3     Employees of the Company. During the Restricted Period,
the Executive shall not induce or attempt to influence any employee of the
Company or any of its affiliates or subsidiaries to terminate such employee's
employment.

               3.1.4     Confidential Information.  The Executive acknowledges
that the Company and its subsidiaries have a legitimate and continuing
proprietary interest in the protection of their confidential information. In
exchange for the Company and its subsidiaries providing the Executive access to
such confidential information, the Executive agrees not to make any unauthorized
use, publication, or disclosure, during or subsequent to his employment by the
Company, of any confidential information, generated or acquired by the Executive
during the course of his employment by the Company, except to the extent that
the disclosure of such confidential information is necessary to fulfill his
responsibilities as an employee of the Company. As used herein, "confidential

and design projects, inventions and research projects, ideas, discoveries,
inventions, improvements, trade secrets and other proprietary information of the
Company or its subsidiaries. This Section 3.1.4 shall survive indefinitely the
termination of this Agreement.

               3.1.5     Company's Interest. The Executive agrees that these
covenants are made to protect the legitimate business interests of the Company,
including interests in the Company's property described in and pursuant to
Section 3.1.2, and not to restrict his mobility or to prevent him from utilizing
his general technical skills. The Executive understands as a part of these
covenants that the Company intends to exercise whatever legal recourse against
him for any breach of this Agreement and, in particular, for any breach of these
covenants.

          3.2  Rights and Remedies Upon Breach.  If the Executive breaches any
of the provisions contained in Section 3.1 of this Agreement (the "Restrictive
Covenants"), the Company shall have the following rights and remedies, each of
which rights and remedies shall be independent of the others and severally
enforceable, and each of which is in addition to, and not in lieu of, any other
rights and remedies available to the Company under law or in equity:

                                           5
<PAGE>

               3.2.1     Specific Performance. The right and remedy to have the
Restrictive Covenants specifically enforced by any court of competent
jurisdiction, it being agreed that any breach of the Restrictive Covenants would
cause irreparable injury to the Company and that money damages would not provide
an adequate remedy to the Company.

               3.2.2     Accounting. The right and remedy to require the
Executive to account for and pay over to the Company, all compensation, profits,
monies, accruals, increments or other benefits derived or received by the
Executive as the result of any action constituting a breach of the Restrictive
Covenants.

          3.3  Severability of Covenants.  The Executive acknowledges and agrees
that the Restrictive Covenants are reasonable and valid in duration and
geographical scope and in all other respects. If any court determines that any
of the Restrictive Covenants, or any part thereof, is invalid or unenforceable,
the remainder of the Restrictive Covenants shall not thereby be affected and
shall be given full effect without regard to the invalid portions.

          3.4  Court Review. If any court determines that any of the Restrictive
Covenants, or any part thereof, is unenforceable because of the duration or
geographical scope of, or scope of activities restrained by, such provision,
such court shall have the power to reduce the duration or scope of such
provision, as the case may be, and, in its reduced form, such provision shall
then be enforceable.

          3.5  Enforceability in Jurisdictions.  The Company and the Executive
intend to and hereby confer jurisdiction to enforce the Restrictive Covenants
upon the courts of any jurisdiction within the geographical scope of such
Restrictive Covenants. If the courts of any one or more of such jurisdictions
hold the Restrictive Covenants unenforceable by reason of the breadth of such
scope or otherwise, it is the intention of the Company that such determination
not bar or in any way affect the right of the Company to the relief provided
above in the courts of any other jurisdiction within the geographical scope of
such Restrictive Covenants, as to breaches of such Restrictive Covenants in such
other respective jurisdictions, such Restrictive Covenants as they relate to
each jurisdiction being, for this purpose, severable into diverse and
independent covenants.

     4.   Termination.

          4.1  Termination Upon Death.  If the Executive dies during the Term,
this Agreement shall terminate; provided, however, that in any such event, the
Company shall pay to the Executive's estate (i) any portion of the Annual Salary
and any accrued Incentive Bonuses that shall have been earned by the Executive
prior to the termination but not yet paid, 

                                            6
<PAGE>

(ii) any Benefits that have vested in the Executive at the time of such 
termination as a result of his participation in any of the Company's benefit 
plans (which shall be paid in accordance with the provisions of such plan), 
and (iii) reimbursement for any expenses with respect to which the Executive 
is entitled to reimbursement pursuant to Section 2.5 of this Agreement, 
within thirty (30) days after such termination. The Executive's right to 
indemnification, payment or reimbursement pursuant to Section 6 of this 
Agreement shall not be affected by such termination and shall continue in 
full force and effect, both with respect to proceedings that are threatened, 
pending or completed at the date of such termination and with respect to 
proceedings that are threatened, pending or completed after that date.

          4.2  Termination With Cause.  The Company has the right, at any time
during the Term, subject to all of the provisions hereof, exercisable by serving
notice, effective on or after the date of service of such notice as specified
therein, to terminate the Executive's employment under this Agreement and
discharge the Executive with Cause.  If such right is exercised, the Company's
obligation to the Executive shall be limited solely to the payment of unpaid
Annual Salary accrued, together with accrued but unpaid Incentive Bonuses, if
any, and Benefits vested up to the effective date specified in the Company's
notice of termination. As used in this Agreement, the term "Cause" shall mean
and include (i) chronic alcoholism or controlled substance abuse as determined
by a doctor of medicine selected by the Company that is authorized to practice
medicine by the State of Texas and whose practice is located in Houston, Texas,
(ii) an act of proven fraud or dishonesty on the part of the Executive, (iii)
knowing and material failure by the Executive to comply with material applicable
laws and regulations relating to the business of the Company or its
subsidiaries; (iv) the Executive's material and continuing failure to perform
(as opposed to unsatisfactory performance) his duties hereunder or a material
breach by the Executive of this Agreement except) in each case, where such
failure or breach is caused by the illness or other similar incapacity or
disability of the Executive; or (v) conviction of a crime involving moral
turpitude or a felony.  Prior to the effectiveness of termination for Cause
under subclause (i), (ii), (iii) or (iv) above, the Executive shall be given 30
days' prior written notice from the Committee specifically identifying the
reasons which are alleged to constitute Cause for any termination hereunder and
an opportunity to be heard by the Committee in the event the Executive disputes
such allegations. This Agreement shall not be terminated for Cause under
subclause (i), (iii) or (iv) above if the reasons which are alleged to
constitute Cause under such subclauses shall no longer exist and shall not be
continuing within thirty (30) days of the receipt of such notice by the
Executive; provided, however, that the Executive shall not have such right to
cure pursuant to the foregoing sentence and prevent termination for Cause if (i)
substantially the same reasons constituting Cause previously occurred and were
the basis for a previous termination notice to the Executive from the Committee,
and (ii) this Agreement was not terminated based on such previous occurrence
because the reasons which were alleged to constitute Cause no 

                                        7
<PAGE>

longer existed and were not continuing within thirty (30) days of the 
Executive's receipt of such notice.

          4.3  Termination Without Cause.  The Company has the right, at any
time during the Term, subject to all of the provisions hereof, exercisable by
serving notice, effective on or after the date of service of such notice as
specified therein, to terminate the Executive's employment under this Agreement
and discharge the Executive without Cause. If the Executive is terminated during
the Term without Cause (including any termination which is deemed to be a
constructive termination without Cause under Section 4.6 hereof), the Company's
obligation to the Executive shall be limited solely to the payment, at the times
and upon the terms provided for herein, of (i) two times the Average
Compensation (as hereinafter defined) and (ii) any unpaid Incentive Bonuses and
Benefits awarded or accrued up to the date of termination. In the event of a
termination by the Company without Cause within nine months before or after a
Change of Control of the Company (as hereinafter defined), including a
constructive termination without Cause pursuant to Section 4.6, the amount due
to the Executive pursuant to clause (i) of the preceding sentence (the
"Severance Payments") shall be increased to three times the Average
Compensation. Any amounts due to the Executive pursuant to clause (ii) of the
second sentence of this Section 4.3 shall be due and payable within thirty (30)
days after the date of termination.  The Severance Payments shall be due and
payable in twenty-four (24) equal monthly payments, or in thirty-six (36) equal
monthly payments in the event of a termination by the Company without Cause in
connection with a Change of Control of the Company pursuant to the preceding
sentence, beginning thirty (30) days after the date of termination. 
Notwithstanding anything herein to the contrary, the Restricted Period, and the
Company's obligations to pay additional Severance Payments to the Executive,
shall be subject to early termination, and shall terminate immediately, at any
time after the Executive is terminated without Cause upon the earlier to occur
of (a) the Executive giving written notice to the Company that he is terminating
the Restricted Period effective upon receipt of such notice by the Company, or
effective at any designated time thereafter (not to exceed thirty (30) days
after the Company's receipt of such notice), (b) the Executive's violation of
any of the provisions of Section 3, or (c) the end of the twenty-four or
thirty-six month period, as applicable, for payment of the Severance Payments
pursuant to the terms hereof.  Upon any termination pursuant to the preceding
clauses(a) or (b) (in either case an "Early Termination"), no further Severance
Payments shall be payable for periods after the effective date of such Early
Termination, except for amounts payable by the Company to the Executive for
periods prior to the effective date of such Early Termination.  The Executive
and the Company agree that the foregoing right of the Company to terminate the
Severance Payments shall be enforceable by the Company notwithstanding any
ruling by any court or any arbitrator that one or more of the provisions of
Section 3 are unenforceable for any reason whatsoever. For purposes hereof,
"Average Compensation" shall mean (x) the average of the 

                                            8
<PAGE>

Annual Salary earned by the Executive during the two years preceding the date 
of termination, or (y) if this Agreement has been in effect for less than two 
years on the date of such early termination, (A) the total Annual Salary 
earned by the Executive during the period from the Effective Date to the date 
of such termination, divided by (B) the total number of days in such period, 
multiplied by (C) 365.

          4.4  Termination by the Executive.  Any termination of this Agreement
by the Executive during the Term, except such termination as is deemed to be a
constrictive termination without Cause by the Company under Section 4.6 of this
Agreement, shall entitle the Company to discontinue payment of all Annual
Salary, Incentive Bonuses and Benefits not earned and payable prior to the date
of such termination.

          4.5  Termination Upon Disability.  If during the Term the Executive
becomes physically or mentally disabled, whether totally or partially, as
evidenced by the written statement of a competent physician licensed to practice
medicine in the United States who is mutually acceptable to the Company and the
Executive or his closest relative if he is not then able to make such a choice,
so that the Executive is unable substantially to perform his services hereunder
for (i) a period of four consecutive months, or (ii) for shorter periods
aggregating 120 days during any twelve-month period, the Company may at any time
after the last day of the four consecutive months of disability or the day on
which the shorter periods of disability equal an aggregate of 120 days, by
written notice to the Executive, terminate the Executive's employment hereunder
and discontinue payments of the Annual Salary, Incentive Bonuses and Benefits
accruing from and after the date of such termination. The Executive shall be
entitled to the full compensation payable to him hereunder for periods of
disability shorter than the periods specified in clauses (i) and (ii) of the
previous sentence.

          4.6  Constructive Termination Without Cause. Notwithstanding any other
provision of this Agreement, the Executive's employment under this Agreement may
be terminated during the Term by the Executive, which shall be deemed to be
constructive termination by the Company without Cause, if one of the following
events shall occur without the consent of the Executive: (i) a failure to elect
or reelect or to appoint or reappoint the Executive to the office of President
and Chief Executive Officer of the Company or other material change by the
Company of the Executive's functions, duties or responsibilities which change
would reduce the ranking or level, dignity, responsibility, importance or scope
of the Executive's position with the Company from the position and attributes
thereof described in Section 1 above; (ii) the assignment or reassignment by the
Company of the Executive to a location not within 20 miles of the Company's
current location; (iii) the liquidation, dissolution consolidation or merger of
the Company, or transfer of all or substantially all of its assets, other than
(a) a consolidation or merger in which the Company is the sole surviving entity
or 

                                       9
<PAGE>

(b) a transaction in which a successor corporation with a net worth
substantially the same as or greater than that of the Company assumes this
Agreement and all obligations and undertakings of the Company hereunder; (iv) a
reduction in the Executive's fixed salary below $200,000 per year or change by
the Company without the consent of the Executive in the method of determining
the Executive's annual bonus that results in a reduction of such annual bonus;
(v) the failure of the Company to continue to provide the Executive with office
space, related facilities, staff and secretarial assistance that are
commensurate with the Executive's responsibilities to and position with the
Company; (vi) the notification by the Company of the Company's intention not to
observe or perform one or more of the material obligations of the Company under
this Agreement; (vii) the failure by the Company to indemnify, pay or reimburse
the Executive at the time and under the circumstances required by Section 6 of
this Agreement; (viii) failure of the Company to pay the Annual Salary, the
Incentive Bonus or any other compensation or amounts payable hereunder when due;
or (ix) the occurrence of any other material breach of this Agreement by the
Company or any of its subsidiaries. Any such termination shall be made by
written notice to the Committee, specifying the event relied upon for such
termination and given within 90 days after such event. Any constructive
termination shall be effective 30 days after the date the Committee has been
given such written notice setting forth the grounds for such termination with
specificity; provided, however, that the Executive shall not be entitled to
terminate this Agreement in respect of any of the grounds set forth above if
within 30 days after such notice the action constituting such ground for
termination has been cured and is no longer continuing.

          4.7  Change of Control.  For the purposes hereof, a "Change of Control
of the Company" shall be deemed to have occurred if any person or group of
persons that are directly or indirectly actively engaged, in whole or in part,
in the Drilling Business (as hereinafter defined) acquire, directly or
indirectly, (i) the power to direct or cause the direction of the management or
policies of the Company. whether through the ownership of voting securities or
other equity interests, by contract or otherwise, including without limitation,
the acquisition of membership interests or other securities of the Company
representing 50% or more of the combined voting power of the Company's then
outstanding securities; (ii) all or substantially all of the assets of the
Company, including, without limitation, in the case of either of the preceding
subsections (i) and (ii), pursuant to a sale, transfer, assignment or other
conveyance of membership interests or other securities, merger, consolidation,
exchange of securities, sale, transfer, assignment or other conveyance of assets
or plan of liquidation or other reorganization, and whether by operation of law
or otherwise. As used herein, the term "Drilling Business" shall mean the
business of owning, leasing, managing or operating drilling rigs, which drilling
rigs and associated crews are contracted or hired by third parties for the
purpose of drilling oil and gas wells. For purposes of determining if a Change
of Control of the Company has occurred, any person owning less than 10% of the
voting securities or other 

                                        10
<PAGE>

equity interests in the Company shall be excluded from the analysis under the 
preceding subclause (i) of this Section 4.7.

          4.8  Limitation on Severe payments. Notwithstanding the provisions of
Section 4.3, if any portion of the amounts payable to the Executive pursuant to
Section 4.3 (the "Total Compensation") constitutes an excess parachute payment
subject to tax pursuant to Section 280G of the Internal Revenue Code of 1986, as
amended, or any successor statute, the Total Compensation shall be reduced to
the minimum extent necessary to insure that no portion of the Total Compensation
is a taxable excess parachute payment. Any such reduction shall be made by
reducing the last payment payable to the Executive as part of the Severance
Payments, and, if necessary, reducing such additional payments in the reverse
order that they are due until the reduction required by the preceding sentence
is accomplished.

     5.    Insurance. The Company may, from time to time, apply for and take
out, in its own name and at its own expense, naming itself or one or more of its
affiliates as the designated beneficiary (which it may change from time to
time), policies for life, health, accident, disability or other insurance upon
the Executive in any amount or amounts that it may deem necessary or appropriate
to protect its interest. The Executive agrees to aid the Company in procuring
such insurance by submitting to medical examinations and by filling out,
executing and delivering such applications and other instruments in writing as
may reasonably be required by an insurance company or companies to which any
application or applications for insurance may be made by or for the Company.

     6.   Indemnification.

          6.1  The Company shall indemnify and hold harmless the Executive from
and against any and all losses, claims, demand, costs, damages, liabilities,
expenses of any nature (including, without limitation, reasonable attorneys'
fees and disbursements), judgments, fines, settlements and other amounts arising
from any and all claims, demands, actions, suits or proceedings, whether civil,
criminal, administrative or investigative, in which the Executive may be
involved, or threatened to be involved, as a party or otherwise, arising out of
or incidental to the business of the Company or its affiliates or subsidiaries,
including, without limitation, liabilities under the federal and state
securities laws, regardless of whether the Executive continues to be employed by
the Company or such affiliate or subsidiary at the time any such liability or
expense is paid or incurred, if (i) the Executive acted in good faith and in a
manner he reasonable believed to be in, or not opposed to, the interests of the
Company and, with respect to any criminal proceeding, had no reason to believe
his conduct was unlawful, and (ii) the Executive's conduct did not constitute
actual fraud, gross negligence or willful or wanton misconduct. The termination
of any action, suit or proceeding by judgment, order, 

                                          11
<PAGE>

settlement, conviction, or upon a plea of nolo contendere, or its equivalent, 
shall not, in and of itself, create a presumption or otherwise constitute 
evidence that the Executive acted in a manner contrary to that specified in 
(i) or (ii) above.

          6.2  Expenses (including, without limitation, reasonable legal fees
and expenses) incurred in defending any proceeding subject to Section 6.1 shall
be paid by the Company in advance of the final disposition of such proceeding
upon receipt of a written affirmation by the Executive of his good fifth belief
that he has met the standard of conduct necessary for indemnification under this
Section 6 and a written undertaking (which need not be secured) by or on behalf
of the Executive to repay such amount if it shall be ultimately determined, by a
court of competent jurisdiction or otherwise, that the Executive is not entitled
to be indemnified by the Company as authorized hereunder.

          6.3  The indemnification provided by this Section 6 shall be in
addition to any other rights to which the Executive may be entitled under any
agreement or vote of the Committee by the vote of Managers that are
disinterested and unaffiliated with the Executive, as a matter of law or
otherwise, both as to action in the Executive's capacity as an officer and
employee of the Company or as a person serving at the request of the Company and
shall continue after the Executive has ceased to serve in such capacity and
shall inure to the benefit of the heirs, administrators and personal
representatives of the Executive.

          6.4  The Company may purchase and maintain directors and officers
insurance or similar coverage for its Managers and officers, including the
Executive, in such amounts and with such deductibles or self-insured retentions
as are customary for persons engaged in businesses similar in size and type to
those ended in by the Company.

          6.5  The Executive shall not be denied indemnification in whole or in
part under this Section 6 because the Executive had an interest in the
transaction with respect to which the indemnification applies if the transaction
was otherwise permitted by the terms of this Agreement and all material facts
relating to the executive's interest were adequately disclosed to the Committee
at the time the transaction was consummated.

          6.6  The provisions of this Section 6 are for the benefit of the
Executive and his heirs, administrators and personal representatives and shall
not be deemed to create any rights for the benefit of any other persons. The
provisions of this Section 6 shall survive termination of this Agreement for any
reason or cause.

     7.   Other Provisions.

                MANAGEMENT AND ADMINISTRATIVE SERVICES AGREEMENT

    This Management and Administrative Services Agreement, dated as of February
27, 1998, is entered into by and between SEACOR SMIT Inc., a Delaware
corporation ("SEACOR"), and Chiles Offshore LLC, a Delaware limited liability
company ("Chiles").

                              W I T N E S S E T H :

    WHEREAS, SEACOR has been providing the services of Dick H. Fagerstal, Vice
President, Finance, of SEACOR ("Mr. Fagerstal"), to assist in the management and
administration of Chiles; and

    WHEREAS, the parties hereto desire that (i) SEACOR continue to provide the
services of Mr. Fagerstal to Chiles, (ii) SEACOR provide additional management
or administrative services to Chiles from time to time as needed and (iii)
SEACOR and Chiles formalize their agreement with respect thereto;

    NOW, THEREFORE, in consideration of the premises and the covenants and
agreements contained herein, the parties hereto, intending to be legally bound,
hereby agree as follows:


                                    ARTICLE I
                     MANAGEMENT AND ADMINISTRATIVE SERVICES

    1.1 SEACOR agrees to continue to provide the services of Mr. Fagerstal to
Chiles substantially in accordance with current practice. At the conclusion of
each calendar month, SEACOR shall render an invoice to Chiles for its fee for
such services, which fee shall be equal to $15,000 if Mr. Fagerstal devoted
substantially all of his business time and attention to the business of Chiles
during the applicable month and shall be proportionately reduced to the extent
that Mr. Fagerstal devotes a portion of his business time and attention to other
business matters during such month. Chiles shall pay to SEACOR the amount of
each such monthly invoice promptly following receipt thereof.

    1.2 Subject to prior agreement between SEACOR and Chiles as to the specific
nature and extent of services to be provided by SEACOR and the compensation to
be paid to SEACOR therefor, SEACOR will furnish, or cause its


<PAGE>


affiliates to furnish Chiles with such of the following services as may be
requested by Chiles from time to time (such services together with the services
of Mr. Fagerstal referred to in Section 1.1 being referred to collectively as
"Management Services"):

         (i) General management and financial services, including, without
    limitation, periodic advice and consultation in connection with corporate,
    legal, finance, accounting, tax, marketing, operations and such other
    matters as may be required in connection with the day-to-day operation of
    Chiles; it being hereby understood that such advice and consultation may,
    from time to time, be provided by professional advisors engaged by SEACOR or
    its affiliates, in which case, the fees and disbursements of such advisors
    shall either be billed directly to Chiles or reimbursed to SEACOR, as SEACOR
    may direct;

         (ii) General administrative services, including without limitation,
    secretarial support services, office equipment and facilities, and access to
    salaried and non-salaried administrative and executive personnel of SEACOR
    or its affiliates;

         (iii) Services of specified individuals employed by SEACOR or its
    affiliates;

         (iv) Investment banking services, including, without limitation,
    assisting Chiles in identifying sources of debt and/or equity financing and
    in consummating debt or equity financings; and

         (v) Such additional services as may be mutually agreed upon from time
    to time by the parties hereto.

                                   ARTICLE II
                          COMPENSATION & REIMBURSEMENT

    2. In consideration for any Management Services provided in accordance with
Article I hereof, it is contemplated that Chiles shall pay SEACOR fees that do
not exceed fees charged by unrelated persons for comparable services. Except as
provided in Section 1.1, SEACOR and Chiles shall agree upon the compensation to
be paid to SEACOR by Chiles on or prior to SEACOR's provision of such services;
provided, however, in the event that, at Chiles' request, SEACOR provides
Management Services to Chiles in the absence of an agreement on compensation,
Chiles agrees to pay to SEACOR fees equal to the reasonable value of



                                        2


<PAGE>


the Management Services provided. Chiles further agrees to reimburse SEACOR for
all reasonable out-of-pocket expenses incurred in connection with any Management
Services provided hereunder promptly following receipt of documentation thereof.


                                   ARTICLE III
                                      TERM

    3. This Agreement shall commence on the date hereof and shall continue until
terminated by either party hereto upon not less than 60 days' prior written
notice of termination to the other party; provided, however, that the provisions
of Article VI hereof shall continue in full force and effect following any such
termination.


                                   ARTICLE IV
                                  FORCE MAJEURE

    4. If, at any time during the term hereof SEACOR is unable to perform
(whether in whole or in part) any of its obligations under this Agreement by
reason of the occurrence of any event or series of events beyond its control,
then, in such case, the performance of such obligations shall be suspended to
the extent and during the time that such performance is so affected; provided,
however, that SEACOR has notified Chiles promptly of such circumstances and has
used its best efforts to perform its obligations hereunder. Compensation payable
by Chiles to SEACOR for Management Services pursuant to this Agreement shall be
proportionately reduced to the extent of the non-performance by SEACOR of its
obligations as provided in this Section 4.

                                    ARTICLE V
                           OTHER ACTIVITIES OF SEACOR

    5. It is hereby acknowledged and understood that officers and employees of
SEACOR (including, without limitation, Mr. Fagerstal) may be subject to
conflicts in the allocation of management and administrative time, services or
functions between Chiles and other entities to which services of the nature
contemplated by this Agreement are provided. Nothing set forth in this Agreement
is intended to, nor shall anything set forth in this Agreement operate to,
restrict


                                        3




<PAGE>


SEACOR, its officers or its employees from providing to other entities
management and administrative services of the nature contemplated by this
Agreement.


                                   ARTICLE VI
                            INDEMNIFICATION OF SEACOR

    6.1 Chiles hereby agrees, to the fullest extent permitted by law, to
indemnify and hold harmless SEACOR, its officers, directors, employees, agents
and "affiliates" (as such term is defined in Rule 12b-2 under the Securities
Exchange Act of 1934, as amended) (collectively, for the purposes of this
Section Six, the "SEACOR Indemnitees") from and against, any and all losses,
claims, demands, costs, damages, liabilities, expenses of any nature (including,
without limitation, reasonable attorneys' fees and disbursements), judgments,
fines, settlements and other amounts arising from any and all claims, demands,
actions, suits or proceedings, whether civil, criminal, administrative or
investigative, in which a SEACOR Indemnitee may be involved, or threatened to be
involved, as a party or otherwise, arising out of, based upon or relating to the
provision of Management Services by SEACOR hereunder (collectively, the
"Indemnified Matters"), except for any such Indemnified Matters that are
adjudged by a court of competent jurisdiction to have resulted from the gross
negligence, bad faith or willful misconduct of SEACOR.

    6.2 For purposes of this Article VI, the termination of any proceeding by
settlement shall not, of itself, create a presumption that any SEACOR Indemnitee
acted in a manner which constituted gross negligence, bad faith or willful
misconduct; provided, however, that a SEACOR Indemnitee shall neither settle,
nor arrange for or stipulate to the settlement of, any Indemnified Matters
without the prior written consent of Chiles, which consent shall not be
unreasonably withheld or delayed. It is hereby acknowledged that any SEACOR
Indemnitee's right to the indemnification provided herein shall be cumulative
of, and in addition to, any and all rights to which a SEACOR Indemnitee may
otherwise be entitled by contract or as a matter of law or equity and shall
extend to its successors, assigns and legal representatives.

                                   ARTICLE VII
                                     NOTICE

    7. All notices, requests, demands and other communications provided for by
this Agreement shall be made in writing and shall be deemed to have been

any other breach or default of the same provision or any other provision of this
Agreement.

special purpose Delaware corporation and a wholly owned subsidiary of Chiles, as
co-issuers (collectively, the "Company"), the 10% Senior Notes due 2008 (the
"Old Notes") described above pursuant to the Company's offer of $1,000 principal
amount of 10% Senior Notes due 2008 (the "New Notes") in exchange for each
$1,000 principal amount of the Old Notes, upon the terms and subject to the
conditions contained in the Prospectus dated       , 1998 (the "Prospectus"),
receipt of which is hereby acknowledged, and in this Letter of Transmittal
(which together constitute the "Exchange Offer").
 
    2.  The undersigned hereby represents and warrants that it has full
authority to tender the Old Notes described above. The undersigned will, upon
request, execute and deliver any additional documents deemed by the Company to
be necessary or desirable to complete the tender of Old Notes.
 
    3.  The undersigned understands that the tender of the Old Notes pursuant to
all of the procedures set forth in the Prospectus will constitute an agreement
between the undersigned and the Company as to the terms and conditions set forth
in the Prospectus.
 
    4.  The undersigned hereby represents and warrants that:
 
       (i)  the New Notes acquired pursuant to the Exchange Offer are being
            obtained in the ordinary course of business of the undersigned,
            whether or not the undersigned is the holder;
 
       (ii)  neither the undersigned nor any such other person is engaging in or
             intends to engage in a distribution of such New Notes;
 
       (iii) neither the undersigned nor any such other person has an
             arrangement or understanding with any person to participate in the
             distribution of such New Notes; and
 
       (iv)  neither the holder nor any such other person is an "affiliate," as
             such term is defined under Rule 405 promulgated under the

account were not acquired as a result of market-making or other trading
activities, such Old Notes cannot be exchanged pursuant to the Exchange Offer.

successors, assigns, executors, administrators, trustees in bankruptcy and legal

<PAGE>
                                  INSTRUCTIONS
 
    1.  GUARANTEE OF SIGNATURES. Signatures on this Letter of Transmittal must
be guaranteed by an eligible guarantor institution that is a member of or
participant in the Securities Transfer Agents Medallion Program, the New York
Stock Exchange Medallion Signature Program, the Stock Exchange Medallion
Program, or by an "eligible guarantor institution" within the meaning of Rule
17Ad-15 promulgated under the Exchange Act (an "Eligible Institution") unless
the box entitled "Special Registration Instructions" or "Special Delivery
Instructions" above has not been completed or the Old Notes described above are
tendered for the account of an Eligible Institution.
 
    2.  DELIVERY OF LETTER OF TRANSMITTAL AND OLD NOTES. The Old Notes, together
with a properly completed and duly executed Letter of Transmittal (or copy
thereof), should be mailed or delivered to the Exchange Agent at the address set
forth above; PROVIDED, HOWEVER, that holders who tender their Old Notes using
The Depository Trust Company's ATOP procedures do not need to mail or deliver a
Letter of Transmittal to the Exchange Agent.
 
    THE METHOD OF DELIVERY OF OLD NOTES AND THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF
THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN
OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO
LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO THE COMPANY. HOLDERS MAY
REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES, OR
NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH HOLDERS.
 
    3.  SIGNATURE ON LETTER OF TRANSMITTAL, BOND POWERS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by a person other than a registered holder
of any Old Notes, such Old Notes must be endorsed or accompanied by appropriate
bond powers, signed by such registered holder exactly as such registered
holder's name appears on such Old Notes.
 
    If this Letter of Transmittal or any Old Notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations, or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and, unless waived by the Company,
proper evidence satisfactory to the Company of their authority to so act must be
submitted with this Letter of Transmittal.
 
    4.  MISCELLANEOUS. All questions as to the validity, form, eligibility
(including time of receipt), acceptance, and withdrawal of tendered Old Notes
will be determined by the Company in its sole discretion, which determination
will be final and binding on all parties. The Company reserves the absolute
right to reject any or all Old Notes not properly tendered or any Old Notes the
Company's acceptance of which would, in the opinion of counsel for the Company,
be unlawful. The Company also reserves the right to waive any defects,
irregularities, or conditions of tender as to particular Old Notes. The
Company's interpretation of the terms and conditions of the Exchange Offer
(including the instructions in this Letter of Transmittal) will be final and
binding. Unless waived, any defects or irregularities in connection with tenders
of Old Notes must be cured within such time as the Company shall determine.
Neither the Company, the Exchange Agent, nor any other person shall be under any
duty to give notification of defects in such tenders or shall incur any
liability for failure to give such notification. Tenders of Old Notes will not
be deemed to have been made until such defects or irregularities have been cured
or waived. Any Old Notes received by the Exchange Agent that are not properly
tendered and as to which the defects or irregularities have not been cured or
waived will be returned by the Exchange Agent to the tendering holder thereof as
soon as practicable following the Expiration Date.
