         THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M. NEW YORK CITY TIME
                    ON              , 1998, UNLESS EXTENDED
                          ---------------------------
          [GULFMARK OFFSHORE LOGO]
 
     GulfMark Offshore, Inc., a Delaware corporation (the "Company"), hereby
offers, upon the terms and subject to the conditions set forth in this
Prospectus and the accompanying Letter of Transmittal, to exchange $1,000
principal amount of its 8 3/4% Senior Notes Due 2008, (the "Exchange Notes"), in
a transaction registered under the Securities Act of 1933, as amended (the
"Securities Act"), pursuant to a Registration Statement (as defined herein) of
which this Prospectus constitutes a part, for each $1,000 principal amount of
the outstanding 8 3/4% Senior Notes due 2008 (the "Old Notes"), of which
$130,000,000 aggregate principal amount is outstanding (the "Exchange Offer").
The Exchange Notes and the Old Notes are sometimes referred to herein
collectively as the "Notes."
 
     The Notes will be general unsecured obligations of the Company and will be
pari passu in right of payment with all existing and future unsecured senior
Indebtedness (as defined herein) of the Company, which may include certain
borrowings under the New Credit Facility (as defined herein), and senior to all
future subordinated indebtedness of the Company. The Company conducts its
operations solely through its Subsidiaries (as defined herein) and, accordingly,
the Notes will be effectively subordinated to (i) all future secured obligations
of the Company to the extent of the assets securing such obligations and (ii)
all existing and future indebtedness and other obligations of the Company's
Subsidiaries and trade payables incurred in the ordinary course of business.
Under certain circumstances, the Company's payment obligations under the Notes
may in the future be jointly and severally guaranteed on a senior unsecured
basis by one or more of the Company's Subsidiaries. See "Description of the
Notes." As of March 31, 1998, on a pro forma basis, after giving effect to the
Offering (as defined herein) and the application of the net proceeds therefrom,
and excluding borrowings that are available under the New Credit Facility, the
Company (exclusive of its Subsidiaries) would have had no Indebtedness
outstanding other than the Notes, and the Company's Subsidiaries would have had
Indebtedness of $0.6 million outstanding. See "Prospectus Summary -- The Private
Placement" and "Description of Other Indebtedness -- New Credit Facility."
 
     The Company will accept for exchange any and all Old Notes that are validly
tendered and not withdrawn prior to 5:00 p.m., New York City time, on the date
the Exchange Offer expires, which will be             , 1998 unless the Exchange
Offer is extended (the "Expiration Date"). Tenders of Old Notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the business day before
the Expiration Date. The Exchange Offer is not conditioned upon any minimum
principal amount of Old Notes being tendered for exchange. However, the Exchange
Offer is subject to the terms and provisions of the Registration Rights
Agreement (as defined herein). See "The Exchange Offer." Old Notes may be
tendered only in denominations of $1,000 and integral multiples thereof. The
Company has agreed to pay the expenses of the Exchange Offer. There will be no
cash proceeds to the Company from the Exchange Offer. See "Use of Proceeds."
 
     The Exchange Notes will be obligations of the Company entitled to the
benefits of the Indenture (as defined herein) relating to the Notes. The form
and terms of the Exchange Notes are identical in all material respects to the
form and terms of the Old Notes, except that (i) the offering of the Exchange
Notes has been registered under the Securities Act, (ii) the Exchange Notes will
not be subject to transfer restrictions and (iii) the Exchange Notes will not be
entitled to registration or other rights under the Registration Rights Agreement
for payment of Liquidated Damages (as defined in the Registration Rights
Agreement (as defined herein)) upon failure by the Company to consummate the
Exchange Offer or the occurrence of certain other events. Following the Exchange
Offer, any holders of Old Notes will continue to be subject to the existing
restrictions on transfer thereof and, as a general matter, the Company will not
have any further obligation to such holders to provide for registration under
the Securities Act of transfers of the Old Notes held by them. To the extent
that Old Notes are tendered and accepted in the Exchange Offer, a holder's
ability to sell untendered and tendered but unaccepted Old Notes could be
adversely affected. See "Risk Factors -- Consequences of Failure to Exchange"
and "The Exchange Offer -- General."
 
     The Old Notes were sold by the Company on June 8, 1998, to Lehman Brothers
Inc., Chase Securities Inc., Jefferies & Company, Inc. and The Robinson-Humphrey
Company (the "Initial Purchasers") in transactions not registered under the
Securities Act in reliance upon the exemption provided in Section 4(2) of the
Securities Act (the "Offering"). The Initial Purchasers placed the Old Notes
with qualified institutional buyers (as defined in Rule 144A under the
Securities Act) ("Qualified Institutional Buyers" or "QIBs"), each of whom
agreed to comply with certain transfer restrictions and other restrictions.
Accordingly, the Old Notes may not be reoffered, resold or otherwise transferred
in the United States unless such transaction is registered under the Securities
Act or an applicable exemption from the registration requirements of the
Securities Act is available. The Exchange Notes are being offered hereby in
order to satisfy the obligations of the Company under the Registration Rights
Agreement among the Company and the Initial Purchasers dated as of June 8, 1998
relating to the Old Notes (the "Registration Rights Agreement").
 
                                                        (Continued on next page)

    FOR A DISCUSSION OF CERTAIN FACTORS THAT SHOULD BE CONSIDERED IN CONNECTION
WITH AN INVESTMENT IN THE NOTES, SEE "RISK FACTORS," BEGINNING ON PAGE 14.
                          ---------------------------
  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
   AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
         ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO
                      THE CONTRARY IS A CRIMINAL OFFENSE.
 
                  THE DATE OF THIS PROSPECTUS IS JULY   , 1998
<PAGE>   4
 
     The Exchange Notes will bear interest at a rate of 8 3/4% per annum,
payable semi-annually on June 1 and December 1 of each year, commencing December
1, 1998. Holders of Exchange Notes of record on November 15, 1998, will receive
on December 1, 1998, an interest payment in an amount equal to (x) the accrued
interest on such Exchange Notes from the date of issuance thereof to December 1,
1998, plus (y) the accrued interest on the previously held Old Notes from the
date of issuance of such Old Notes (June 8, 1998) to the date of exchange
thereof. Interest will not be paid on Old Notes that are accepted for exchange.
The Notes mature on June 1, 2008.
 
     The Old Notes were initially represented by one global note in registered,
global form without interest coupons (the "Old Global Note") registered in the
name of Cede & Co., as nominee for The Depository Trust Company (the
"Depositary"), as depositary. The Exchange Notes exchanged for Old Notes
represented by the Old Global Note will also be initially represented by one
global note in registered, global form without interest coupons (the "Exchange
Global Note") registered in the name of Cede & Co. as nominee for the
Depositary. See "Description of the Notes -- Book-Entry; Delivery and Form." The
Old Global Note and the Exchange Global Note are sometimes referred to herein
collectively as the "Global Notes."
 
     Based on interpretations of the Securities Act by the staff of the
Securities and Exchange Commission (the "Commission"), Exchange Notes issued
pursuant to the Exchange Offer in exchange for Old Notes may be offered for
resale, resold and otherwise transferred by a holder thereof (other than (i) a
broker-dealer who purchased such Old Notes directly from the Company for resale
pursuant to Rule 144A or any other available exemption under the Securities Act
or (ii) a person that is an "affiliate" (within the meaning of Rule 405 of the
Securities Act) of the Company), without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that the holder
is acquiring the Exchange Notes in its ordinary course of business and is not
participating, and has no arrangement or understanding with any person to
participate, in the distribution of the Notes. Holders of Old Notes wishing to
accept the Exchange Offer must represent to the Company that such conditions
have been met.
 
     Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer must agree that it will deliver a prospectus in
connection with any resale of such Exchange Notes. 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
Exchange 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 Company has agreed that, for a period of 180 days after
the date the Registration Statement has been declared effective by the
Commission, it will make this Prospectus available to any broker-dealer for use
in connection with any such resale. See "Plan of Distribution."
 
     The Exchange Notes will be a new issue of securities for which there
currently is no market. The Company does not intend to list the Notes on any
national securities exchange or to seek admission thereof to trading on the
Nasdaq National Market. Although the Initial Purchasers have informed the
Company that they currently intend to make a market in the Exchange Notes, they
are not obligated to do so, and any such market making may be discontinued at
any time without notice. Accordingly, there can be no assurance as to the
development, liquidity or maintenance of any market for the Exchange Notes on
any securities exchange. See "Risk Factors -- Absence of a Public Market for the
Exchange Notes."

involved in the offshore exploration and production of oil and natural gas. The
Company's vessels provide various services, including the transportation of
materials, supplies and personnel, and the positioning of drilling structures,
that support the construction and ongoing operation of offshore oil and natural
gas facilities and drilling rigs (collectively "Offshore Marine Services"). The
majority of the Company's operations are conducted in the North Sea and the
balance are conducted in Southeast Asia and offshore Brazil. After giving effect
for the Brovig Acquisition (as defined herein), the Company generated $29.8
million of pro forma EBITDA for the 12 months ended December 31, 1997. See
"-- Summary of Historical Condensed Consolidated Financial and Other Data."
 
     The size, diversity and technologically advanced nature of GulfMark's fleet
enables it to provide offshore exploration and production operators with a broad
range of Offshore Marine Services in several key markets. The Company's fleet
has grown in size and capability from an original 11 vessels acquired in late
1990 to 34 vessels as of March 31, 1998, through strategic acquisitions and new
construction of technologically advanced vessels. Twenty-seven vessels in
GulfMark's fleet are owned, two vessels are bareboat chartered, and five vessels
are managed by the Company. The Company believes its fleet is among the youngest
in the industry, with an average age of 14 years. Excluding the six vessels
acquired by the Company from Maritime (Pte), Limited in August 1996, all of the
Company's owned vessels have been built or substantially refurbished since 1984.
 
     The Company's North Sea fleet is comprised of vessels with a wide range of
technological capabilities and sizes. This fleet is heavily oriented toward
supply vessels, which tend to work in the more stable industry sub-segments of
platform supply and field development. The average age of the Company's North
Sea fleet is just over ten years.
 
     On March 7, 1998, GulfMark took delivery of its most modern,
technologically sophisticated vessel to date, the Highland Rover, a modified and
extended (236(#)) UT 755 platform supply vessel. The Company also acquired five
vessels as part of the Brovig Acquisition during the first quarter of 1998. See
"-- Recent Developments." As a result of the delivery of the Highland Rover and
the Brovig Acquisition, the Company's fleet includes four owned UT 755s, the
Highland Rover, the Highland Drummer, the North Challenger, and the Highland
Piper, each built and delivered since 1996. These four vessels are currently
under contract in the North Sea.
 
     The Company's Southeast Asia fleet consists of vessels that can
individually provide the greatest functional flexibility for the varied needs of
this geographically diverse region. Substantially all of the Company's vessels
in the Southeast Asia fleet have sufficient anchor handling and towing
capability to compete for work in areas such as Indonesia, where drilling and
production support are major users of offshore support vessels. Additionally,
the vessels are attractive as supply vessels in locales such as Thailand and
Malaysia because of their combination of on-deck and below-deck capacities and
relatively high horsepower.

     The Company plans to add six newly built vessels to the fleet during the
balance of 1998 and six additional newbuilds in 1999. Three of those 12 new
vessels will be owned by the Company. The Company has commenced construction in
the United Kingdom to complete an unfinished vessel hull (the "Gallant
Project"). The Company currently intends to complete the vessel as a
multi-purpose support vessel for the floating production, storage and offloading
("FPSO") market, although it still has the capacity and flexibility to complete
the vessel as a platform supply vessel ("PSV"). The Company anticipates that
delivery of the Gallant Project will occur in October 1998. The Company believes
that the comparatively low hull acquisition and completion cost (estimated at
$16.0 million, excluding capitalized interest), and the 1998 delivery of the
Gallant Project should provide the Company with a significant competitive
advantage in serving the rapidly growing FPSO market. In addition, two large
PSVs are currently under construction for the Company by Bender Shipbuilding and
Repair Co., Inc. ("Bender") in Mobile, Alabama. These vessels will be able to
operate in harsher climates and deeper water environments than traditional
supply vessels built in the U.S. for use in the Gulf of Mexico. The two Bender
vessels are scheduled for delivery in early and mid 1999, respectively, at an
estimated cost, excluding capitalized interest, of $11.0 million each. The
Company has an option with Bender to construct two additional vessels of similar
design, which, if such option is exercised, could be available in 2000.
 
     The financial performance of the Company reflects both the growth of its
fleet and strong demand in its primary markets. GulfMark's average day rate for
its owned North Sea PSVs for the quarter ended March 31, 1998 was $10,511 per
day, compared to $9,575 per day for the quarter ended March 31, 1997. The
average day rate for its Southeast Asia fleet was $4,771 per day for the quarter
ended March 31, 1998 compared to $3,538 per day for the quarter ended March 31,
1997. The Company's owned vessels operating in the North Sea accounted for 70.6%
of the Company's vessel earnings (revenues less direct costs) in the quarter
ended March 31, 1998. The Company expects this percentage to increase as a
result of the Brovig Acquisition and the delivery of the Highland Rover.
 
     The Company is a Delaware corporation with principal executive offices
located at 5 Post Oak Park, Suite 1170, Houston, Texas 77027-3414, and its
telephone number at that address is (713) 963-9522.
 
BUSINESS STRATEGY
 
     GulfMark's goal is to enhance its position as a premier supplier of
Offshore Marine Services in international markets. The Company's strategy is to
profitably increase revenues and enhance shareholder value by (i) developing and
maintaining a large, diversified and technologically sophisticated fleet, (ii)
focusing on attractive international markets and (iii) managing its risk profile
through a balance of long-term and short-term charters. The Company believes
this strategy, coupled with an emphasis on providing dependable, high quality
services, will produce higher vessel utilization rates, relatively stable growth
rates and returns on investments that are superior to those of the Company's
competitors.
 
  Developing and Maintaining a Large, Diversified and Technologically Advanced
Fleet
 
     The Company regularly upgrades its fleet to improve capability, reliability
and customer satisfaction. The Company also seeks to take advantage of
attractive opportunities to acquire or build new vessels to expand its fleet.
With the delivery of the Highland Rover and the other planned 1998 and 1999
fleet additions, the Company will own and/or operate nine of the fourteen UT 755
design PSVs currently in service or on order worldwide. The UT 755 is a
technologically sophisticated design the Company helped introduce in the North
Sea with the construction of the Highland Piper and Highland Drummer, two of the
first three UT 755s built (in 1996 and 1997, respectively). The design has been
favorably received by the market and is now gaining wide acceptance.
 
  Focusing on Attractive International Markets
 
     GulfMark has elected to focus its current operations in the North Sea,
Southeast Asia and Brazil markets because the Company believes there are lower
levels of competition, higher barriers to entry, lower volatility of day rates
and greater potential for increasing day rates in those markets than in other
markets, such as in the
 
                                        2
<PAGE>   9
 
Gulf of Mexico. Furthermore, the Company's operating experience in these markets
has enabled it to anticipate and profitably respond to trends in these markets,
such as the increasing demand for multi-function vessels met by the Company's
addition of UT 705s and UT 755s in its North Sea fleet. In addition, the Company
has the capacity, under appropriate market conditions, to alter the geographic
focus of its operations to a limited degree by shifting vessels between its
existing markets and by entering new ones as they develop economically and
become more profitable.
 
     North Sea. Historically, this market has been the most demanding of all oil
and natural gas exploration frontiers due to harsh weather, erratic sea
conditions, significant water depths and long sailing distances. Exploration and
production operators in the North Sea market are typically large and well
capitalized entities (such as major oil companies and state-owned oil
companies), in large part because of the significant financial commitment
required for projects in this market. North Sea projects require comparatively
long planning horizons, and while still large compared to projects in other
markets, are becoming smaller in scale and greater in number due to the
reduction in breakeven economics encouraged by advancing technology.
Consequently, vessel demand in the North Sea tends to be relatively steady and
less susceptible to abrupt swings than vessel demand in other regions. The
Company's management has been active in this market since the mid-1970s.
 
     Southeast Asia. Vessel requirements in this fragmented market are trending
towards higher quality, younger vessels as local certification standards have
generally become more demanding. As a result, vessel requirements in Southeast
Asia are now generally similar to the requirements in the Gulf of Mexico.
However, varying weather conditions (such as annual monsoons) and long distances
between supply centers and delivery locations demand more versatile vessel
designs than those used in the Gulf of Mexico. The Company believes that vessel
demand in this market will remain strong and potentially improve further as a
function of the number of major exploration and production projects currently in
the planning stages and the reliable supply of stable foreign currency generated
for the region's economies by the production of hydrocarbons. The Company's
management has been involved in Offshore Marine Services activities in this
market since the mid-1970s, and the Company maintains long-standing business
relationships with a number of local companies.
 
     Brazil. Vessel requirements in this market are similar to those of the
North Sea due to the harsh operating environment. In addition, this market is
expected to expand at a rapid rate due to the privatization of Petroleo
Brasiliero S.A. ("Petrobras"), the Brazilian national oil company, and the
potential grant of concessions of Brazil's offshore acreage to international oil
companies. The Company's Brazil fleet currently consists of one vessel, the
Seapower, which has been operating in this market since 1995 and is currently
under charter to Petrobras through May 1999. Following its delivery in mid-1998,
the Leopard Bay will operate in this market under a three-year contract with
Petrobras. The Company believes that both its current vessel and the planned
vessel additions in 1998 and 1999 are well-suited to this market. The Company
expects that it will expand its presence in this market going forward.
 
  Managing Its Risk Profile Through a Balance of Long-Term and Short-Term
Charters
 
     The Company seeks to balance its portfolio of charters with both long-term
charters, which provide a significant degree of cash flow certainty, and
short-term charters and sharing arrangements, which provide the opportunity to
benefit when day rates are increasing. The Company utilizes its many years of
operating experience to apply this strategy within the markets in which it
operates. Approximately 63% of the Company's revenues for the first three months
of 1998 were derived from charters that will continue until at least the fourth
quarter of 1998. These contracts are typically associated with the Company's
newer vessels, predominantly in the North Sea. Moreover, certain of these
contracts include extension options. As of March 31, 1998, the Company estimates
that it will have $56.6 million and $39.2 million of revenues under such
contracts in 1999 and 2000, respectively, assuming that the options are
exercised.
 
     The Company has also selectively employed sharing arrangements with its
customers to enhance its profitability on longer term charters. These innovative
charters provide the Company and its customers the opportunity to benefit from
rising charter rates by subchartering the contracted vessels to third parties at
prevailing market rates during any downtime in the customers' operations. If the
subcharter rate is below the
 
                                        3
<PAGE>   10
 
original charter rate, the customer remains obligated for the contracted rate
shortfall. However, if the subcharter rate is higher than the original charter
rate, the Company and the customer share the additional revenues. These
arrangements permit both the customer and the Company to benefit from improving
market conditions and reduce any disincentive to customers from entering into
longer term charters by minimizing down time costs.
 
RECENT DEVELOPMENTS
 
  The Brovig Acquisition
 
     In February 1998, the Company acquired substantially all of Brovig Supply
ASA (renamed Gulf Offshore Norge AS) ("Brovig"), at the time a Norwegian-owned,
publicly traded company(the "Brovig Acquisition"). The Company completed the
Brovig Acquisition in March 1998. Brovig was formed through a spin-off from its
former parent on July 1, 1997 in connection with a new tax regime for
ship-owning companies in Norway. The Brovig fleet consists of four large PSVs,
including a UT 755 (the North Challenger) delivered in December 1997, and one
large anchor handling, towing and supply ("AHTS") vessel. All of these vessels
are currently operating in the North Sea. Four of the vessels are under charters
with expiration dates ranging from February 1999 to May 2000, and one vessel has
recently been awarded a construction support contract at premium rates for
summer 1998. The purchase consideration for the Brovig Acquisition was
approximately $73.0 million, including the assumption of approximately NOK 277
million ($37.4 million) of indebtedness.
 
  Delivery of the Highland Rover
 
     On March 7, 1998, the Company took delivery of the Highland Rover, a
modified, extended UT 755 PSV. The UT 755 is a technologically sophisticated
design that has been favorably received by the market and is now gaining wide
acceptance. Additionally, with increasing demand for use of subsea remotely
operated vehicles ("ROVs"), vessels such as the Highland Rover, with its
specialized "moon pool" ROV launching arrangement, are expected to be especially
attractive because they provide customers with increased launch certainty in
harsh and unpredictable weather, such as that experienced in the North Sea. Upon
delivery, the Company paid the balance of the construction cost, 93.4 million
Norwegian Kroner ("NOK") (or $14.0 million), with additional borrowings under an
existing credit facility. The Highland Rover was immediately employed under a
three-year charter at an attractive rate with a marine contractor.
 
  New Credit Facility
 
     The Company applied the net proceeds of the Offering to repay in full the
amounts owing at the time of the closing of the Offering under each of its
then-existing credit facilities and such facilities have since been terminated.
See "-- The Private Placement." In place of these multiple facilities, on June
8, 1998 the Company entered into a single multicurrency revolving loan agreement
(the "New Credit Facility"), initially in an aggregate principal amount of $50.0
million and potentially up to an aggregate principal amount of $75.0 million.
The New Credit Facility is available to provide financing for future
acquisitions, working capital and other general corporate purposes. See
"Description of Other Indebtedness -- New Credit Facility."
 
  Sale of Interest in SeaMark Ltd.
 
     On July 8, 1998 the Company sold for $3 million in cash, its interest in
its 51% owned joint venture, SeaMark Ltd., which operated two bareboat chartered
vessels in Southeast Asia. Gain from the transaction is expected to approximate
the proceeds of sale and will be included in the Company's results for the
quarter ended September 30, 1998.

                             THE PRIVATE PLACEMENT
 
     The Old Notes were sold by the Company on June 8, 1998 to the Initial
Purchasers and were thereupon offered and sold by the Initial Purchasers only to
certain Qualified Institutional Buyers. Of the $125.7 million net proceeds
received by the Company in connection with the sale of the Old Notes, $119.6
million was used to repay in full amounts owing at the time of the closing of
the Offering under each of the Company's then-existing credit facilities. The
remaining $6.1 million of such net proceeds will be used for general corporate
purposes, including a portion of the capital expenditures associated with
vessels currently under construction. As of March 31, 1998, on a pro forma
basis, after giving effect to the Offering and the application of the net
proceeds as just described, and excluding borrowings that are available under
the New Credit Facility, the Company (exclusive of its Subsidiaries) would have
had no Indebtedness outstanding other than the Notes, and the Company's
Subsidiaries would have had Indebtedness of $0.6 million outstanding. See
"Capitalization."

REGISTRATION RIGHTS
AGREEMENT..................  The Old Notes were sold by the Company on June 8,
                             1998 to the Initial Purchasers pursuant to a
                             Purchase Agreement, dated June 2, 1998 (the
                             "Purchase Agreement"). Pursuant to the Purchase
                             Agreement, the Company and the Initial Purchasers
                             entered into the Registration Rights Agreement
                             which, among other things, grants the holders of
                             the Old Notes certain exchange and registration
                             rights. The Exchange Offer is intended to satisfy
                             certain obligations of the Company under the
                             Registration Rights Agreement.
 
THE EXCHANGE OFFER.........  $1,000 principal amount of Exchange Notes will be
                             issued in exchange for each $1,000 principal amount
                             of Old Notes validly tendered and accepted pursuant
                             to the Exchange Offer. As of the date hereof,
                             $130,000,000 in aggregate principal amount of Old
                             Notes are outstanding. The Company will issue the
                             Exchange Notes to tendering holders of Old Notes
                             promptly following the Expiration Date. The terms
                             of the Exchange Notes are identical in all material
                             respects to the Old Notes except for certain
                             transfer restrictions and registration rights
                             relating to the Old Notes.
 
                             No federal or state regulatory requirements must be
                             complied with or approval obtained in connection
                             with the Exchange Offer, other than the
                             registration requirements under the Securities Act.
 
RESALE.....................  Based on existing interpretations of the Securities
                             Act by the staff of the Commission set forth in
                             several no-action letters to third parties, and
                             subject to the immediately following sentence, the
                             Company believes that Exchange Notes issued
                             pursuant to the Exchange Offer in exchange for Old
                             Notes may be offered for resale, resold and
                             otherwise transferred by holder thereof (other than
                             (i) a broker-dealer who purchased such Old Notes
                             directly from the Company for resale pursuant to
                             Rule 144A or any other available exemption under
                             the Securities Act or (ii) a person that is an
                             "affiliate" (within the meaning of Rule 405 of the
                             Securities Act) of the Company), without compliance
                             with the registration and prospectus delivery
                             provisions of the Securities Act, provided that the
                             holder is acquiring the Exchange Notes in its
                             ordinary course of business and is not
                             participating, and has no arrangement or
                             understanding with any person to participate, in
                             the distribution of the Exchange Notes. However,
                             any purchaser of Notes who is an affiliate of the
                             Company or who intends to participate in the
                             Exchange Offer for the purpose of distributing the
                             Exchange Notes, or any broker-dealer who purchased
                             the Old Notes from the Company to resell pursuant
                             to Rule 144A or any other available exemption under
                             the Securities Act,

<PAGE>   13
 
                             (i) will not be able to rely on the interpretations
                             by the staff of the Commission set forth in the
                             above-mentioned no-action letters, and (ii) must
                             comply with the registration and prospectus
                             delivery requirements of the Securities Act in
                             connection with any sale or transfer of the Notes
                             unless such sale or transfer is made pursuant to an
                             exemption from such requirements. The Company does
                             not intend to seek its own no-action letter and
                             there is no assurance that the staff of the
                             Commission would make a similar determination with
                             respect to the Exchange Notes as it has in such
                             no-action letters to third parties. See "The
                             Exchange Offer -- General" and "Plan of
                             Distribution." Each broker-dealer that receives
                             Exchange 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 Exchange Notes. 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 Exchange Notes received in exchange
                             for Old Notes where such Old Notes were acquired by
                             such broker-dealer as a result of market-making

                             other things, the Exchange Notes acquired pursuant
                             to the Exchange Offer are being acquired in the
                             ordinary course of business of the person receiving
                             such Exchange Notes, whether or not such person is
                             the holder, that neither the holder nor any such
                             other person has any arrangement or understanding
                             with any person to participate in the distribution
                             of such Exchange Notes and that neither the holder
                             nor any such other person is an "affiliate," as
                             defined in rule 405 under the Securities Act, of
                             the Company. See "The Exchange Offer -- Procedures
                             for Tendering."
 
                             Following consummation of the Exchange Offer,
                             holders of Old Notes not tendered as a general
                             matter will not have any further registration
                             rights, and the Old Notes will continue to be
                             subject to certain restrictions on transfer.
                             Accordingly, the liquidity of the market for the
                             Old Notes could be adversely affected. See "Risk
                             Factors -- Absence of Public Market for the
                             Exchange Notes" and "-- Consequences of Failure to
                             Exchange" and "The Exchange Offer -- Consequences
                             of Failure to Exchange."
 
SPECIAL PROCEDURES FOR
BENEFICIAL OWNERS..........  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 in the Exchange Offer should contact such
                             registered holder promptly and instruct such
                             registered holder to tender on his behalf. If such
                             beneficial owner wishes to tender on his own
                             behalf, such beneficial owner must, prior to
                             completing and executing the Letter of Transmittal
                             and delivering his Old Notes, either (a) make
                             appropriate arrangements to register ownership of
                             the Old Notes in such holder's name or (b) obtain a
                             properly completed bond power from the registered

                             Old Notes to be tendered. The transfer of record
                             ownership may take considerable time, and
                             completion of such transfer prior to the Expiration
                             Date may not be possible. See "The Exchange

                             Holders."
 
RANKING....................  The Notes will be general unsecured obligations of
                             the Company and will be pari passu in right of
                             payment to all existing and future senior
                             Indebtedness, including all obligations of the
                             Company under the New Credit Facility. The Company
                             conducts its operations solely through its
                             subsidiaries and, accordingly, the Notes will be
                             effectively subordinated to all existing and future
                             Indebtedness and other liabilities of its
                             subsidiaries. As of March 31, 1998, after giving
                             pro forma effect to the Offering and the
                             application of the net proceeds therefrom, and
                             excluding borrowings that are available under the
                             New Credit Facility, the Company (exclusive of its
                             Subsidiaries) would have had no Indebtedness
                             outstanding other than the Notes, and the Company's
                             Subsidiaries would have had Indebtedness of
                             approximately $0.6 million outstanding. See
                             "Prospectus Summary -- The Private Placement,"
                             "Capitalization" and "Description of the
                             Notes -- General."
 
SUBSIDIARY GUARANTEES......  Under certain circumstances, the Company's payment
                             obligations under the Notes may in the future be
                             jointly and severally guaranteed on a senior
                             unsecured basis by one or more of the Company's
                             Subsidiaries. See "Description of the
                             Notes -- Subsidiary Guarantees."
 
CERTAIN COVENANTS..........  The Indenture pursuant to which the Notes will be
                             issued (the "Indenture") contains certain covenants
                             that, among other things, limit the ability of the
                             Company and the Company's Subsidiaries to (i) incur
                             additional indebtedness, (ii) pay dividends or make
                             certain other re-

                             stricted payments, (iii) enter into transactions
                             with affiliates, (iv) create certain liens, (v)
                             make certain asset dispositions and (vi) merge or
                             consolidate with, or transfer substantially all of
                             its assets to, another person. The Indenture also
                             limits the ability of the Company's Subsidiaries to
                             issue preferred stock and to create restrictions on
                             the ability of such Subsidiaries to pay dividends
                             or make any other distributions. In addition, the
                             Company is obligated, under certain circumstances,
                             to offer to purchase the Notes with the net cash
                             proceeds of certain sales and other dispositions of
                             assets at a purchase price of 101% of the principal
                             amount of the Notes, plus accrued and unpaid
                             interest and, in the case of the Old Notes only,
                             Liquidated Damages, if any, to the date of
                             purchase. See "Description of the
                             Notes -- Repurchase at the Option of Holders" and
                             "-- Certain Covenants."
 
EXCHANGE OFFER,
REGISTRATION RIGHTS........  Pursuant to the Registration Rights Agreement, the
                             Company agreed (i) to file a registration statement
                             (the "Exchange Offer Registration Statement") with
                             respect to the Exchange Offer to exchange the Old
                             Notes for Exchange Notes within 60 days after the
                             date of the original issuance of the Old Notes
                             (which was June 8, 1998) and (ii) to use their best
                             efforts to cause such registration statement to
                             become effective within 150 days after such issue
                             date. The Registration Statement of which this
                             Prospectus is a part constitutes such Exchange
                             Offer Registration Statement. If (i) the Exchange
                             Offer is not permitted by applicable law or (ii)
                             any holder of the Notes notifies the Company that
                             (A) it is prohibited by law or policy of the
                             Commission from participating in the Exchange
                             Offer, (B) it may not resell the Exchange Notes
                             acquired by it in the Exchange Offer to the public
                             without delivering a prospectus and the prospectus
                             contained in the Exchange Offer Registration
                             Statement is not appropriate or available for such
                             resales or (C) it is a broker-dealer and owns Notes
                             acquired directly from the Company or an affiliate
                             of the Company, the Company will use its best
                             efforts to cause to become effective a shelf
                             registration statement (the "Shelf Registration
                             Statement") to cover resales of the Notes by the
                             holders thereof. If the Company fails to satisfy
                             these registration obligations within prescribed
                             time periods, it may be required to pay Liquidated
                             Damages to holders of Old Notes under certain
                             circumstances. See "Description of the
                             Notes -- Registration Rights; Liquidated Damages."
 
TRANSFER RESTRICTIONS......  Following the Exchange Offer, any Old Notes not
                             exchanged for Exchange Notes will continue to be
                             subject to the existing restrictions on transfers
                             thereof and may not be offered or sold within the
                             U.S. or to, or for the benefit of, U.S. persons
                             except pursuant to an exemption from, or in a
                             transaction not subject to, the registration
                             requirements of the Securities Act. See "The
                             Exchange Offer -- Consequences of Failure to
                             Exchange." The Exchange Notes would, in general, be
                             freely tradable after the Exchange Offer. See
                             "Exchange Offer."

     SUMMARY OF HISTORICAL CONDENSED CONSOLIDATED FINANCIAL AND OTHER DATA
 
     The summary historical financial information presented below under
Operating Data, for each of the three years in the period ended December 31,
1997, has been derived from the historical consolidated financial statements of
the Company, which have been audited by Arthur Andersen LLP, independent
auditors. The historical information for the three months ended March 31, 1997
and 1998 is unaudited. The unaudited historical information is taken from
unaudited financial statements that include all adjustments, which are of a
normal recurring nature, which the Company considers necessary for a fair
presentation of the results of operations for these periods. Operating results
for the three months ended March 31, 1998 are not necessarily indicative of the
results that may be expected for the entire year ending December 31, 1998. The
information presented should be read together with "Selected Consolidated
Financial Data" and the Consolidated Financial Statements including the notes
thereto incorporated by reference in this Prospectus. The Consolidated Financial
Statements included in this Prospectus, as well as the financial data presented
in the table below, present the net assets and results of operations of the
non-marine businesses of the Company's Predecessor as discontinued operations of
the Company for all periods presented. See "The Company."

(a)  EBITDA represents operating income plus depreciation and amortization.
     While EBITDA should not be construed as a substitute for operating income
     or as a better indicator of liquidity than cash flows from operating
     activities, which are determined in accordance with generally accepted
     accounting principles, EBITDA is included herein to provide additional
     information with respect to the ability of the Company to meet its future
     debt service, capital expenditures and working capital requirements. EBITDA
     is not necessarily a measure of the Company's ability to fund its cash
     needs. EBITDA is included herein because the Company believes that certain
     investors find it to be a useful tool for measuring the ability to service
     debt.
 
(b)  This computation is submitted in accordance with Item 503(d) of Regulation
     S-K. Earnings are computed as income from continuing operations before
     taxes and minority interest plus fixed charges and minority interest in
     income of subsidiary. Fixed charges are computed as interest, whether
     expensed or capitalized, amortization of debt discount and issuance costs
     and the portion of rental expense representative of interest.
 
(c)  Includes current portion of long-term debt.
 
(d)  Excludes discontinued operations which were disposed of on May 1, 1997.

                                  RISK FACTORS
 
     Prospective investors in the Notes should carefully review the information
contained elsewhere in this Prospectus and should particularly consider the
following matters:
 
DEPENDENCE ON OIL AND GAS INDUSTRY; MARKET VOLATILITY
 
     The Company's operations are dependent on activity in the offshore oil and
natural gas exploration and production industry. The level of exploration and
development of offshore areas is affected by both short-term and long-term
trends in oil and natural gas prices which, in turn, are related to the demand
for petroleum products and the current availability of oil and natural gas
resources. The level of offshore activity is also related to local policies that
influence drilling activities. In recent years, oil and natural gas prices have
reacted to actual and perceived changes in the supply of and demand for oil and
natural gas, which has resulted in volatile levels of offshore exploration and
drilling activity. A significant or prolonged decline in future oil and natural
gas prices would likely result in reduced exploration and development of
offshore areas and a decline in the demand for Offshore Marine Services. Such
reduced activity could have a material adverse effect on the Company's financial
condition and results of operations.
 
     Charter rates for the Company's vessels are also dependent on the supply of
offshore support vessels. Excess vessel capacity in the industry can result from
refurbishment of "mothballed" vessels, conversion of vessels formerly dedicated
to services other than Offshore Marine Services, construction of new vessels and
migration of vessels between markets. The continued recent additions of new
capacity to the worldwide offshore marine fleet could increase competition in
those markets where the Company presently operates, which in turn, could have a
material adverse effect on the Company's financial condition and results of
operations.
 
HIGHLY LEVERAGED POSITION
 
     The Company is highly leveraged. As of March 31, 1998, after giving pro
forma effect to the Offering and the application of net proceeds therefrom, and
excluding borrowings that are available under the New Credit Facility, the
Company (exclusive of its Subsidiaries) would have no Indebtedness outstanding
other than the Notes, and the Company's Subsidiaries would have had Indebtedness
of $0.6 million outstanding. See "Capitalization" and "Selected Historical
Consolidated Financial Information." The Company's ability to make required
principal and interest payments on its indebtedness is dependent on the future
performance of the Company and its Subsidiaries. The Company's performance is
subject to a number of factors beyond its control, including the performance of
the global economy and financial markets, worldwide demand for oil and gas and
other factors affecting the Company and its Subsidiaries. Additionally, the
Indenture will impose certain operating and financial restrictions on the
Company and its Subsidiaries. Such restrictions will affect, and in many
respects will limit or prohibit, among other things, the ability of the Company
and its Subsidiaries to incur additional Indebtedness, pay dividends, permit
Subsidiaries to issue preferred stock, repay certain indebtedness prior to its
stated maturity, create liens, sell assets or engage in mergers or acquisitions
and make certain capital expenditures. These restrictions, in combination with
the leveraged nature of the Company, could limit the ability of the Company to
effect future financings or otherwise restrict corporate activity.
 
     The Company's level of indebtedness and the restrictive covenants contained
in its debt instruments, including the Indenture, could significantly limit the
Company's ability to withstand competitive pressures or adverse economic
consequences, including the ability of the Company to make capital expenditures
for new vessel construction and other investments in its fleet. In addition,
borrowings under the New Credit Facility will be floating rate obligations of
the Company and its Subsidiaries, causing the Company and its Subsidiaries to be
sensitive to changes in prevailing interest rates. The Company currently
believes that, based on current levels of operations and anticipated growth, its
cash flow from operations, together with borrowings that are available from time
to time under the New Credit Facility, will be adequate to allow for anticipated
capital expenditures for vessel construction and fleet upgrades, to fund working
capital requirements and to make required payments of principal and interest on
its debt. However, if the Company is unable to generate sufficient cash flow
from operations in the future, it may be required to refinance all or a portion
of its debt or
 
                                       14
<PAGE>   21
 
to obtain additional financing. There can be no assurance that any such
refinancing would be possible or that any additional financing would be
obtained.
 
HOLDING COMPANY STRUCTURE; RANKING OF THE NOTES; EFFECTIVE SUBORDINATION
 
     The Company will be the sole obligor on the Notes. The Company's operations
are conducted through, and substantially all of the Company's assets are owned
by, its operating Subsidiaries, most of which are organized under foreign
jurisdictions. As a result, the Company will be dependent on the earnings and
cash flow from such Subsidiaries to meet its obligations under the Notes and to
pay its general expenses. It is expected that Subsidiary cash flow will be made
available to the Company through payments on Intercompany Loans (as defined
herein). The Notes will be general unsecured obligations of the Company ranking
pari passu with all existing and future unsecured senior Indebtedness of the
Company, which may include certain borrowings under the New Credit Facility, and
senior to all future Subordinated Indebtedness of the Company. The Notes will be
effectively subordinated, however, to all future secured obligations of the
Company to the extent of the assets securing such obligations. Furthermore,
because the Company's operations are conducted through, and substantially all of
the Company's assets are owned by, its operating Subsidiaries, the Notes will
also be effectively subordinated to all current and future obligations of such
Subsidiaries (including claims of the lenders under the New Credit Facility and
claims of trade creditors). In the event of liquidation or insolvency of the
Company or if any secured indebtedness is accelerated, the secured assets of the
Company will be available to pay obligations on the Notes only after such
secured indebtedness has been paid in full. At March 31, 1998, after giving pro
forma effect to the Offering and the application of the estimated net proceeds
therefrom, and excluding borrowings that are available under the New Credit
Facility, the Company (exclusive of its Subsidiaries) would have had no
Indebtedness outstanding other than the Notes and the Company's Subsidiaries
would have had Indebtedness of $0.6 million outstanding.
 
CONSTRAINTS TO REALIZING CASH FROM SUBSIDIARIES
 
     As the Company's operations are conducted through its Subsidiaries, the
Company will be dependent upon the earnings and cash flow from such Subsidiaries
to meet its obligations under the Notes and to pay its general expenses. In
addition to the risks described above in "-- Holding Company Structure; Ranking
of the Notes; Effective Subordination," the ability of the Company's
Subsidiaries to make payments to the Company may be constrained by (i) the level
of taxation, particularly corporate profits and withholding taxes, in the
jurisdictions in which they operate, (ii) exchange controls and repatriation
restrictions in effect in the jurisdictions in which they operate, and (iii) the
ownership interests of other investors in the Company's Subsidiaries.
 
     Substantially all of the Subsidiaries of the Company have issued
intercompany notes to the Company ("Intercompany Loans"). It is anticipated that
in connection with the application of net proceeds of the Offering, certain
Subsidiaries will issue additional Intercompany Loans to the Company. There can
be no assurance that any of the Intercompany Loans can be enforced easily, if at
all. Substantially all of the Subsidiary makers of the Intercompany Loans are
incorporated in jurisdictions outside the United States. In the event of a
default under an Intercompany Loan, any enforcement action in all likelihood
will have to occur in the jurisdiction where the maker's assets are located. The
limited jurisprudence and experience with such enforcement actions in the
relevant jurisdiction may significantly complicate, delay or limit the scope of
such enforcement action. The ability of a foreign claimant to enforce a judgment
or arbitral award obtained outside those jurisdictions may be limited.
 
RELIANCE ON CERTAIN CUSTOMERS
 
     The Company's principal customers are major integrated oil companies and
large independent oil and natural gas exploration and production companies
operating in international markets, as well as foreign government owned or
controlled organizations and companies that provide logistics, construction and
other services to such oil companies and foreign government organizations. The
percentage of the Company's revenues attributable to a particular customer
varies from time to time depending on the level of oil and
                                       15
<PAGE>   22
 
natural gas exploration undertaken by that customer, the suitability of the
Company's vessels for the customer's projects and other factors, many of which
are beyond the Company's control. For the year ended December 31, 1997,
approximately 16.5%, 15.4% and 13.2% of the Company's total revenues were
received from Aberdeen Services Company (North Sea) ("ASCO"), Shell U.K.
Exploration & Production ("Shell") and European Marine Contractors ("EMC"),
respectively. For the quarter ended March 31, 1998, approximately 17.5%, 14.0%
and 10.5% of the Company's total revenues were received from ASCO, Petronas
Caragali and Shell, respectively.
 
ENVIRONMENTAL AND GOVERNMENT REGULATION
 
     The Company's operations are materially affected by government regulation
in the form of international conventions, federal and state laws and regulations
in jurisdictions where the Company's vessels operate and/or are registered.
These conventions, laws and regulations govern oil spills and other matters of
environmental protection, worker health and safety, as well as the manning,
construction and operation of vessels.
 
     The Company believes that it is presently in material compliance with the
environmental laws and regulations to which the Company's operations are
subject. The Company is not a party to any pending environmental litigation or
other proceeding and is unaware of any threatened litigation or proceeding,
which, if adversely determined, would have a material adverse effect on the
financial condition or results of operations of the Company. However, the risk
of incurring substantial compliance costs, liabilities and penalties for
noncompliance are inherent in Offshore Marine Services operations. There can be
no assurance that significant costs, liabilities and penalties will not be
incurred by or imposed on the Company in the future.
 
OPERATIONAL RISKS AND INSURANCE
 
     The Company's operations are subject to various risks, including
catastrophic marine disaster, adverse weather conditions, mechanical failure,
collision, oil and hazardous substance spills and navigation errors, all of
which represent a threat to the safety of personnel and to the Company's
vessels, cargo, equipment under tow and other property, as well as the
environment. The occurrence of any of the foregoing events could result in loss
of revenue and casualty loss, increased costs or significant liability of the
Company to third parties. Because a significant majority of the Company's vessel
earnings are produced by the 15 owned vessels in its North Sea fleet, the
occurrence of such events with respect to any of those vessels, could have a
disproportionate effect on the Company's revenues and earnings. The Company
maintains insurance coverage that it considers adequate against the casualty and
liability risks listed above, and it has not in the past experienced a loss in
excess of policy limits. There can be no assurance, however, that the Company's
existing insurance coverage can be renewed at commercially reasonable rates or
that such coverage will be adequate to cover future claims that may arise.
 
RELIANCE ON FOREIGN OPERATIONS
 
     For each of the past five years, substantially all of the Company's
revenues from continuing operations were derived from foreign sources. The
Company's foreign operations are subject to various risks inherent in conducting
business in foreign nations. These risks include, among others, political
instability, potential vessel seizure, nationalization of assets, import-export
quotas and other forms of public and governmental regulation, all of which are
beyond the control of the Company. Although the Company's operations,
historically, have not been affected materially by such conditions or events, it
is not possible to predict whether any such conditions or events might develop
in the future. Also, the Company has organized its subsidiary structure and its
operations in part based on certain assumptions about various foreign and
domestic tax laws, currency exchange, and capital repatriation laws and other
relevant laws. While the Company believes that such assumptions are correct,
there can be no assurance that taxing or other authorities will reach the same
conclusion. If such assumptions are incorrect, or if the relevant countries were
to change or modify such laws or the current interpretation thereof, the Company
may suffer adverse tax and financial consequences, including the reduction of
cash flow available to meet required debt service and other obligations.
Finally, the Company conducts operations in the Southeast Asia market and has
significant customers located in
                                       16
<PAGE>   23
 
Indonesia, Thailand and Malaysia. While to date the Company has not experienced
an adverse impact associated with the recent economic events in the region,
there can be no assurance that the recent volatility in Southeast Asian
economies will not adversely affect the Company's business, financial condition
or results of operations.
 
CURRENCY FLUCTUATIONS
 
     Due to its foreign operations, the Company is exposed to foreign currency
exchange rate fluctuations and exchange rate risks. To minimize the Company's
exposure to these risks, the Company attempts to match the currency of the
vessel debt and operating costs with the currency of the charter revenue. For
financial statement reporting purposes, these accounts are translated into U.S.
Dollars at the weighted average exchange rates for the relevant period. From
time to time, the Company enters into forward foreign exchange contracts to
hedge specific exposures but does not engage in currency speculation. Because
the Company conducts a large portion of its operations in foreign currencies, to
the extent the U.S. Dollar appreciates in relation to applicable foreign
currencies, such appreciation could potentially adversely affect the Company's
operating revenues, cash flows and earnings when translated into U.S. Dollars.
To date, currency fluctuations have not had a material impact on the Company's
financial condition or results of operations.
 
ONGOING CAPITAL EXPENDITURE REQUIREMENTS
 
     As of March 31, 1998, the average age of the Company's owned offshore
support vessel fleet was approximately 14 years. The Company believes that after
an offshore support vessel has been in service for approximately 25 years, the
amount of expenditures (which typically increase with vessel age) necessary to
satisfy required marine certification standards may not be economically
justifiable. Although the Company believes that available cash and projected
free cash flow from operations will provide funds sufficient to finance the
remaining cost of the vessels currently scheduled to be delivered, and that
borrowings available under the New Credit Facility will enable the Company to
add additional vessels to its fleet, there can be no assurance that the
Company's financial resources will be sufficient to enable it to maintain its
fleet by extending the economic life of existing vessels through major
refurbishment or by acquiring new or used vessels.
 
COMPETITION
 
     The Company operates in a highly competitive industry. In addition to
price, service and reputation, the principal competitive factors for offshore
support vessel fleets include the existence of national flag preferences,
operating conditions and intended use (all of which determine the suitability of
vessel types), complexity of maintaining logistical support and the cost of
transferring equipment from one market to another. Some of the Company's
competitors have greater financial resources than the Company.
 
RISKS OF CONSTRUCTION DELAYS
 
     The Company's vessel construction projects are subject to the risks of
delay and cost overruns inherent in any large construction project, including
shortages of equipment, unforeseen engineering problems, work stoppages, weather
interference, unanticipated cost increases and shortages of materials or skilled
labor. Significant cost overruns or delays would adversely affect the Company's
financial condition and results of operations. Significant delays could also
result in penalties under, or the termination of, most of the long-term
contracts under which the Company plans to operate these vessels.
 
INDEMNITY OBLIGATIONS TO EVI
 
     See "The Company" for the definitions of certain of the following
capitalized terms.
 
     The Company has agreed to indemnify Energy Ventures, Inc. (now known as
EVI, Inc. ("EVI")) against any tax liabilities in the event the Contribution,
Distribution or Merger is determined to be taxable. EVI and the Predecessor
received a tax opinion that the Contribution, Distribution and Merger would be
tax-free under the Internal Revenue Code of 1986, as amended. If, however,
contrary to the opinion, the
 
                                       17
<PAGE>   24
 
Contribution, Distribution or Merger were ever determined to be taxable, the
potential tax liability to the Company has been estimated to be between $23
million and $36 million.
 
     Additionally, pursuant to the Distribution Agreement, the Company has
agreed to indemnify the Predecessor, EVI and certain of their affiliates against
(i) liabilities for all past and future claims and litigation against EVI or the
Predecessor stemming from the Predecessor's or the Company's Offshore Marine
Services operations, and (ii) liabilities for claims and litigation against EVI
or the Predecessor and its current or past subsidiaries and affiliates,
including the Predecessor's erosion control business ("Ercon"), for periods
prior to May 1, 1997 (the "Distribution Indemnity"). Although the Company has
established a reserve on its Consolidated Balance Sheet which it believes to be
adequate to cover such contingencies, there can be no assurance that the reserve
is adequate.
 
FRAUDULENT CONVEYANCE CONSIDERATIONS
 
     Although there are currently no Subsidiary Guarantees (as defined) with
respect to the Notes, the Company's obligations under the Notes may, under
certain circumstances, be guaranteed on a general unsecured basis in the future
by certain of the Company's domestic subsidiaries. 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 any Subsidiary Guarantee
issued by a Subsidiary Guarantor (as defined). It is also possible that under
certain circumstances a court could hold that the direct obligations of a
Subsidiary Guarantor could be superior to the obligations under the Subsidiary
Guarantee. In addition, to the extent any Subsidiary Guarantor is organized
under the laws of a foreign jurisdiction and the Subsidiary Guarantees were
determined to be subject to the laws of such jurisdiction, the laws of
fraudulent transfer and creditor's rights may be less developed and consequently
the enforcement of Subsidiary Guarantees may be more uncertain in such
jurisdictions.
 
     Generally, to the extent that a United States court were to find that at
the time a Subsidiary Guarantor entered into a Subsidiary Guarantee either (x)
the Subsidiary Guarantee was incurred by a Subsidiary Guarantor with the intent
to hinder, delay or defraud any present or future creditor or that a Subsidiary
Guarantor contemplated insolvency with a design to favor one or more creditors
to the exclusion in whole or in part of others or (y) the Subsidiary Guarantor
did not receive fair consideration or reasonably equivalent value for issuing
the Subsidiary Guarantee and, at the time it issued the Subsidiary Guarantee,
the Subsidiary Guarantor (i) was insolvent or rendered 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 the Subsidiary
Guarantor 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 Subsidiary Guarantor's other obligations. Among other things, a legal
challenge of a Subsidiary Guarantee on fraudulent conveyance grounds may focus
on the benefits, if any, realized by the Subsidiary Guarantor as a result of the
issuance by the Company 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
Subsidiary Guarantor and would be creditors solely of the Company.
 
POTENTIAL INABILITY TO REPURCHASE NOTES UPON CHANGE IN CONTROL
 
     Upon a Change of Control, each holder of the Notes will have the right to
require the Company to repurchase all or any part of such holder's Notes at 101%
of the principal amount thereof, plus accrued and unpaid interest thereon to the
date of repurchase. However, there can be no assurance that sufficient funds
will be available to the Company at the time of any Change of Control to make
any required repurchases of Notes tendered. Moreover, restrictions in the New
Credit Facility prohibit the Company from making such required repurchases.
Therefore, any such repurchases would constitute an event of default under the
New Credit Facility. See "Description of Other Indebtedness -- New Credit
Facility."
 
                                       18
<PAGE>   25
 
ABSENCE OF PUBLIC MARKET FOR THE EXCHANGE NOTES
 
     The Exchange Notes will constitute a new class of securities with no
established trading market. The Company does not intend to list the Notes on any
national securities exchange or to seek the admission thereof to trading in the
Nasdaq National Market. The Exchange Notes are expected to be eligible for
trading in the PORTAL market. The Company has been advised by the Initial
Purchasers that the Initial Purchasers currently intend to make a market in the
Exchange Notes. The Initial Purchasers are not obligated to do so, however, and
any market-making activities with respect to the Exchange Notes may be
discontinued 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. See "Description of the Notes -- Registration Rights; Liquidated
Damages." Accordingly, no assurance can be given that an active public or other
market will develop for the Exchange Notes or as to the liquidity of the trading
market for the Exchange Notes. If a trading market does not develop or is not
maintained, holders of the Exchange Notes may experience difficulty in reselling
the Exchange Notes or may be unable to sell them at all. If a market for the
Exchange Notes develops, any such market may be discontinued at any time. If a
public trading market develops for the Exchange Notes, future trading prices of
the Exchange Notes will depend on many factors, including among other things,
prevailing interest rates, the Company's financial condition and results of
operations, and the market for similar notes. Depending on those and other
factors, the Exchange Notes may trade at a discount from their principal amount.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     The Old Notes have not been registered under the Securities Act or any
state securities laws and, unless so registered, may not be offered or sold
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. Following the consummation of the Exchange Offer, holders who did not
exchange their Old Notes for Exchange Notes generally will not have any further
rights under the Registration Rights Agreement and will remain subject to the
existing restrictions upon transfer of such Old Notes. Because the Company
anticipates that most holders of Old Notes will elect to exchange such Old Notes
for Exchange Notes due to the general lack of restrictions on the resale of
Exchange Notes under the Securities Act, the Company anticipates that the
liquidity of the market for any Old Notes remaining after the consummation of
the Exchange Offer may be substantially limited. See "The Exchange
Offer -- Consequences of Failure to Exchange."

<PAGE>   26
 
                                  THE COMPANY
 
     The Company was incorporated in 1996 as "New GulfMark, Inc.", a wholly
owned subsidiary of the corporation then known as GulfMark International, Inc.
(the "Predecessor"). The Company was formed to facilitate the Predecessor's
separation of its international Offshore Marine Services business from its only
U.S. operations, an erosion control business, and its holdings of EVI common
stock. In order to accomplish this separation, the Predecessor agreed to
transfer the assets, liabilities and operations of its Offshore Marine Services
business to the Company (the "Contribution"). On April 30, 1997, stockholders of
the Predecessor approved the Contribution and the separation of the Offshore
Marine Services business which was accomplished through the distribution of all
the then outstanding Common Stock of the Company to the Predecessor's common
stockholders (the "Distribution") in accordance with the Agreement and Plan of
Distribution dated December 5, 1996 (the "Distribution Agreement") among the
Company, the Predecessor and EVI. Following the Distribution, on May 1, 1997, a
subsidiary of EVI was merged (the "Merger") with and into the Predecessor, whose
assets then consisted solely of Ercon and its investment in approximately 2.2
million shares of EVI common stock.
 
     GulfMark provides marine support and transportation services to companies
involved in the offshore exploration and production of oil and natural gas. The
Company's vessels provide various services, including the transportation of
materials, supplies and personnel, and the positioning of drilling structures,
that support the construction and ongoing operation of offshore oil and natural
gas facilities and drilling rigs. The majority of the Company's operations are
conducted in the North Sea and the balance are conducted in Southeast Asia and
offshore Brazil.
 
     The size, diversity and technologically advanced nature of GulfMark's fleet
enables it to provide offshore exploration and production operators with a broad
range of Offshore Marine Services in several key markets. The Company's fleet
has grown in size and capability from an original 11 vessels acquired in late
1990 to 34 vessels as of March 31, 1998 through strategic acquisitions and new
construction of technologically advanced vessels. Twenty-seven vessels in
GulfMark's fleet are owned, two vessels are bareboat chartered, and five vessels
are managed by the Company. The Company believes its fleet is among the youngest
in the industry, with an average age of 14 years. Excluding the six vessels
acquired by the Company from Maritime (Pte), Limited in August 1996, all of the
Company's owned vessels have been built or substantially refurbished since 1984.
 
     GulfMark's goal is to enhance its position as a premier supplier of
Offshore Marine Services in international markets. The Company's strategy is to
profitably increase revenues and enhance shareholder value by (i) developing and
maintaining a large, diversified and technologically sophisticated fleet, (ii)
focusing on attractive international markets and (iii) managing its risk profile
through a balance of long-term and short-term charters. The Company believes
this strategy, coupled with an emphasis on providing dependable, high quality
services, will produce higher vessel utilization rates, relatively stable growth
rates and returns on investments that are superior to those of the Company's
competitors.
 
     The Company is a Delaware corporation with principal executive offices
located at 5 Post Oak Park, Suite 1170, Houston, Texas 77027-3414, and its
telephone number at that address is (713) 963-9522.
 
                                USE OF PROCEEDS
 
     The Company will not receive any cash proceeds from the issuance of the
Exchange Notes offered hereby. In consideration for issuing the Exchange Notes
as contemplated in this Prospectus, the Company will receive in exchange a like
principal amount of Old Notes, the terms of which are identical in all material
respects to the Exchange Notes. The Old Notes surrendered in exchange for the
Exchange Notes will be retired and canceled and cannot be reissued. Accordingly,
issuance of the Exchange Notes will not result in any change in capitalization
of the Company.
 
                                       20
<PAGE>   27
 
                               PRIVATE PLACEMENT
 
     On June 8, 1998, the Company completed the private sale to the Initial
Purchasers of $130,000,000 principal amount of the Old Notes in a transaction
not registered under the Securities Act in reliance upon Section 4(2) of the
Securities Act. The Initial Purchasers thereupon offered and resold the Old
Notes to Qualified Institutional Buyers. Of the $125.7 million net proceeds
received by the Company in connection with the sale of the Old Notes, $119.6
million was used to repay in full amounts owing at the time of the closing of
the Offering under the Company's then existing credit facilities. The remaining
$6.1 million of such net proceeds will be used for general corporate purposes,
including a portion of the capital expenditures associated with vessels
currently under construction. See "Capitalization."
 
                                 CAPITALIZATION
 
     The following table sets forth the consolidated unaudited capitalization of
the Company at March 31, 1998 and as adjusted to reflect the Offering, assuming
application of the net proceeds therefrom as described under "Prospectus
Summary -- The Private Placement." The Company will fund the remaining cost of
vessels under construction through (i) available cash, (ii) free cash flow from
operations, and (iii) to the extent any additional funds are required,
borrowings under the New Credit Facility. See "Description of Other
Indebtedness -- New Credit Facility." This table should be read in conjunction
with the Consolidated Financial Statements of the Company, including the notes
thereto, incorporated by reference in this Prospectus.

(a)  Earnings per share is based on the weighted average number of shares of

(b)  EBITDA represents operating income plus depreciation and amortization.
     While EBITDA should not be construed as a substitute for operating income
     or as a better indicator of liquidity than cash flows from operating
     activities, which are determined in accordance with generally accepted
     accounting principles, EBITDA is included herein to provide additional
     information with respect to the ability of the Company to meet its future
     debt service, capital expenditures and working capital requirements. EBITDA
     is not necessarily a measure of the Company's ability to fund its cash
     needs. EBITDA is included herein because the Company believes that certain
     investors find it to be a useful tool for measuring the ability to service
     debt.
 
(c)  This computation is submitted in accordance with Item 503(d) of Regulation

     expensed or capitalized, amortization of debt discount and issuance costs
     and the portion of rental expense representative of interest.

                               THE EXCHANGE OFFER
 
GENERAL
 
     The Old Notes were sold by the Company on June 8, 1998, to the Initial
Purchasers pursuant to the Purchase Agreement. The Initial Purchasers
subsequently resold the Old Notes to Qualified Institutional Buyers (as defined
in Rule 144A), each of whom agreed to comply with certain transfer restrictions
and other conditions. As a condition to the purchase of the Old Notes by the
Initial Purchasers, the Company entered into the Registration Rights Agreement
with the Initial Purchasers, which requires, among other things, that promptly
following the issuance and sale of the Old Notes, the Company file with the
Commission the Registration Statement with respect to the Exchange Notes, use
its best efforts to cause the Registration Statement to become effective under
the Securities Act and, upon the effectiveness of the Registration Statement,
offer to the holders of the Old Notes the opportunity to exchange their Old
Notes for a like principal amount of Exchange Notes, which will be issued
without a restrictive legend and may be reoffered and resold by the holder
without restrictions or limitations under the Securities Act subject to certain
exceptions described below. A copy of the Registration Rights Agreement has been
filed as an exhibit to the Registration Statement of which this Prospectus is a
part. The term "holder" with respect to the Exchange Offer means any person in
whose name Old Notes are registered on the Company's books or any other person
who has obtained a properly completed bond power from the registered holder or
any person whose Old Notes are held of record by the Depositary who desires to
deliver such Old Notes by book-entry transfer of the Depositary.
 
     Based on existing interpretations of the Securities Act by the staff of the
Commission set forth in several no-action letters to third parties the Company
believes that Exchange Notes issued pursuant to the Exchange Offer in exchange
for Old Notes may be offered for resale, resold and otherwise transferred by a
holder thereof (other than a "Restricted Holder," being (i) a broker-dealer who
purchased such Old Notes directly from the Company for resale pursuant to Rule
144A or any other available exemption under the Securities Act or (ii) a person
that is an "affiliate" (within the meaning of Rule 405 of the Securities Act) of
the Company), without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that the holder is acquiring the
Exchange Notes in its ordinary course of business and is not participating, and
has no arrangement or understanding with any person to participate, in the
distribution (within the meaning of the Securities Act) of the Exchange Notes.
Eligible Holders wishing to accept the Exchange Offer must represent that the
conditions of the foregoing proviso have been met. However, any purchaser of Old
Notes who is an affiliate of the Company or who intends to participate in the
Exchange Offer for the purpose of distributing the Exchange Notes, or any
broker-dealer who purchased the Old Notes from the Company to resell pursuant to
Rule 144A or any other available exemption under the Securities Act, (i) will
not be able to rely on the interpretations by the staff of the Commission set
forth in such no-action letters and (ii) must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
sale or transfer of the Old Notes unless such sale or transfer is made pursuant
to an exemption from such requirements. Accordingly, any holder who tenders in
the Exchange Offer with the intention to participate, or for the purpose of
participating, in a distribution of the Exchange Notes must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with a secondary resale transaction. See "Plan of Distribution."
 
     As a result of the filing and effectiveness of the Registration Statement
of which this Prospectus is a part, the Company will not be required to pay an
increased interest rate on the Old Notes. Following the consummation of the
Exchange Offer, holders of Old Notes not tendered will not have any further
registration rights except in certain limited circumstances requiring the filing
of a Shelf Registration Statement (as defined), and the Old Notes will continue
to be subject to certain restrictions on transfer. See "Description of the
Notes -- Registration Rights; Liquidated Damages" and "The Exchange
Offer -- Consequences of Failure to Exchange." Accordingly, the liquidity of the
market for the Old Notes could be adversely affected.
 
     This Prospectus, together with the accompanying Letter of Transmittal, is
being sent to all registered holders as of the date of this Prospectus.

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 all Old Notes properly
tendered prior to 5:00 p.m. New York City time, on the Expiration Date and not
timely withdrawn. After authentication of the Exchange Notes by the Trustee or
an authenticating agent, the Company will issue and deliver $1,000 principal
amount of Exchange 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 in denominations of $1,000
and integral multiples thereof.
 
     Each holder of Old Notes who wishes to exchange Old Notes for Exchange
Notes in the Exchange Offer will be required to represent that (i) any Exchange
Notes to be received by it are being acquired in the ordinary course of its
business and (ii) it is not engaged in, and does not intend to engage in, and
has no arrangement or understanding with any person to participate in the
distribution (within the meaning of the Securities Act) of the Exchange Notes
and (iii) it is not an affiliate of the Company or, if it is an affiliate, that
it will comply with applicable registration and prospectus delivery requirements
of the Securities Act.
 
     Each broker-dealer that receives Exchange 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"), must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. Under the
Registration Rights Agreement, the Company is required to allow Participating
Broker-Dealers to use this Prospectus, as it may be amended or supplemented from
time to time, in connection with the resale of such Exchange Notes. See "Plan of
Distribution."
 
     The form and terms of the Exchange Notes are identical in all material
respects to the form and terms of the Old Notes, except that (i) the offering of
the Exchange Notes has been registered under the Securities Act, (ii) the
Exchange Notes will not be subject to transfer restrictions and (iii) the
holders of the Exchange Notes will not be entitled to registration or other
rights under the Registration Rights Agreement including payment of Liquidated
Damages upon failure by the Company to consummate the Exchange Offer or the
occurrence of certain other events. The Exchange Notes will evidence the same
debt as the Old Notes. The Exchange Notes will be issued under and entitled to
the benefits of the Indenture.
 
     As of the date of this Prospectus, $130,000,000 aggregate principal amount
of the Old Notes is outstanding. In connection with the issuance of the Old
Notes, the Company arranged for the Old Notes to be issued and transferable in
book-entry form through the facilities of the Depositary, acting as depositary.
The Exchange Notes will also be issuable and transferable in book-entry form
through the Depositary.
 
     This Prospectus, together with the accompanying Letter of Transmittal, is
initially being sent to all registered holders of the Old Notes as of the close
of business on the date of this Prospectus. 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 thereunder, including Rule
14e-1, to the extent applicable. The Exchange Offer is not conditioned upon any
minimum aggregate principal amount of Old Notes being tendered, and holders of
the Old Notes do not have any appraisal or dissenters' rights under the Delaware
General Corporation Law or under the Indenture in connection with the Exchange
Offer. 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 the
Exchange Agent. See "-- Exchange Agent." The Exchange Agent will act as agent
for the tendering holders for the purpose of receiving Exchange Notes from the
Company and delivering Exchange Notes to such holders.
 
     If any tendered Old Notes are not accepted for exchange because of an
invalid tender or the occurrence of certain other events set forth herein,
certificates for any such unaccepted Old Notes will be returned, at the
Company's cost, 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
 
                                       25
<PAGE>   32
 
certain applicable taxes, in connection with the Exchange Offer. See
"-- Solicitation of Tenders; Fees and Expenses."
 
     NEITHER THE BOARD OF DIRECTORS OF THE COMPANY NOR THE COMPANY MAKES ANY
RECOMMENDATION TO HOLDERS OF OLD NOTES AS TO WHETHER TO TENDER OR REFRAIN FROM
TENDERING ALL OR ANY PORTION OF THEIR OLD NOTES PURSUANT TO THE EXCHANGE OFFER.
MOREOVER, NO ONE HAS BEEN AUTHORIZED TO MAKE ANY SUCH RECOMMENDATION. HOLDERS OF
OLD NOTES MUST MAKE THEIR OWN DECISION WHETHER TO TENDER PURSUANT TO THE
EXCHANGE OFFER AND, IF SO, THE AGGREGATE AMOUNT OF OLD NOTES TO TENDER AFTER
READING THIS PROSPECTUS AND THE LETTER OF TRANSMITTAL AND CONSULTING WITH THEIR
ADVISORS, IF ANY, BASED ON THEIR OWN FINANCIAL POSITION AND REQUIREMENTS.
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
     The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
            , 1998, unless the Company, in its sole discretion, extends the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date to which the Exchange Offer is extended. The Company may extend the
Exchange Offer at any time and from time to time by giving oral or written
notice to the Exchange Agent and by timely public announcement.
 
     The Company expressly reserves the right, in its sole discretion (i) to
delay acceptance of any Old Notes, to extend the Exchange Offer or to terminate
the Exchange Offer and to refuse to accept Old Notes not previously accepted, if
the conditions set forth herein under "-- Conditions of the Exchange Offer"
shall have occurred and shall not have been waived by the Company (if permitted
to be waived by the Company), by giving oral or written notice of such delay,
extension or termination to the Exchange Agent and (ii) to amend the terms of
the Exchange Offer in any manner. Any such delay in acceptance, extension,
termination or amendment will be followed as promptly as practicable by oral or
written notice thereof by the Company to the registered holders of the Old
Notes. If the Exchange Offer is amended in a manner determined by the Company to
constitute a material change, the Company will promptly disclose such amendment
in a manner reasonably calculated to inform the holders of such amendment and
the Company will extend the Exchange Offer to the extent required by law.
 
     Without limiting the manner in which the Company may choose to make public
announcements of any delay in acceptance, extension, termination or amendment of
the Exchange Offer, the Company shall have no obligation to publish, advise or
otherwise communicate any such public announcement, other than by making a
timely release thereof to the Dow Jones News Service.
 
INTEREST ON THE EXCHANGE NOTES
 
     The Exchange Notes will bear interest at a rate of 8 3/4% per annum,
payable semi-annually on June 1 and December 1 of each year, commencing December
1, 1998. Holders of Exchange Notes of record on November 15, 1998, will receive
on December 1, 1998, an interest payment in an amount equal to (i) the accrued
interest on such Exchange Notes from the date of issuance thereof to December 1,
1998, plus (ii) the accrued interest on the previously held Old Notes from the
date of issuance of such Old Notes (June 8, 1998) to the date of exchange
thereof. Interest will not be paid on Old Notes that are accepted for exchange.
The Notes mature on June 1, 2008.
 
PROCEDURES FOR TENDERING
 
     Each holder of Old Notes wishing to accept the Exchange Offer must
complete, sign and date the Letter of Transmittal, or a facsimile thereof, in
accordance with the instructions contained herein and therein, and mail or
otherwise deliver such Letter of Transmittal, or such facsimile, together with
the Old Notes (unless such tender is being effected pursuant to the procedure
for book-entry transfer, as provided for herein) to be exchanged and any other
required documentation, to State Street Bank and Trust Company, as Exchange
 
                                       26
<PAGE>   33
 
Agent prior to 5:00 p.m. New York City time on the Expiration Date, at the
address set forth herein and in the Letter of Transmittal. Only a holder may
tender its Old Notes in the Exchange Offer.
 
     Any financial institution that is a participant in the Depositary's
book-entry transfer facility system may make book-entry delivery of the Old
Notes by causing the Depositary to transfer such Old Notes into the Exchange
Agent's account in accordance with the Depositary's procedure for such transfer.
Although delivery of Old Notes may be effected through book-entry transfer into
the Exchange Agent's account at the Depositary, the Letter of Transmittal (or
facsimile thereof), with any required signature guarantees and any other
required documents, must, in any case, be transmitted to and received by the
Exchange Agent at its address set forth herein under "-- Exchange Agent" prior
to 5:00 p.m., New York City time, on the Expiration Date. DELIVERY OF DOCUMENTS
TO THE DEPOSITARY IN ACCORDANCE WITH ITS PROCEDURES DOES NOT CONSTITUTE DELIVERY
TO THE EXCHANGE AGENT. See "-- Book Entry Transfer."
 
     Any beneficial owner whose Old Notes are registered in the name of his
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact such registered holder promptly and instruct such
registered holder to tender on his behalf. If such beneficial owner wishes to
tender on his own behalf, such beneficial owner must, prior to completing and
executing the Letter of Transmittal and delivering his Old Notes, either make
appropriate arrangements to register ownership of the Old Notes in such owner's
name or obtain a properly completed bond power from the registered holder. The
transfer of record ownership may take considerable time.
 
     If less than all of the Old Notes are tendered, a tendering holder should
fill in the amount of Old Notes being tendered in the appropriate box on the
Letter of Transmittal. The entire amount of Old Notes delivered to the Exchange
Agent will be deemed to have been tendered unless otherwise indicated.
 
     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by a member firm of a registered national
securities exchange or of the National Association of Securities Dealers, Inc.,
a commercial bank or trust company having an office or correspondent in the
United States or an "eligible guarantor institution" within the meaning of Rule
17Ad-15 under the Exchange Act (each an "Eligible Institution"), unless the Old
Notes tendered pursuant thereto are tendered (i) by a registered holder who has
not completed the box entitled "Special Registration Instructions" or "Special
Delivery Instructions" of the Letter of Transmittal or (ii) for the account of
an Eligible Institution. If the Letter of Transmittal is signed by a person
other than the registered holder listed therein, such Old Notes must be endorsed
or accompanied by appropriate bond powers which authorize such person to tender
the Old Notes on behalf of the registered holder, in either case signed as the
name of the registered holder or holders appears on the Old Notes. If the Letter
of Transmittal or any Old Notes or bond powers are signed or endorsed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
person should so indicate when signing, and unless waived by the Company,
evidence satisfactory to the Company of their authority to so act must be
submitted with the Letter of Transmittal.
 
     BY EXECUTING THE LETTER OF TRANSMITTAL, EACH HOLDER WILL REPRESENT TO THE
COMPANY THAT, AMONG OTHER THINGS, (1) THE EXCHANGE NOTES ACQUIRED PURSUANT TO
THE EXCHANGE OFFER ARE BEING ACQUIRED IN THE ORDINARY COURSE OF BUSINESS OF THE
PERSON RECEIVING SUCH EXCHANGE NOTES (WHETHER OR NOT SUCH PERSON IS THE HOLDER),
(2) NEITHER THE HOLDER NOR ANY SUCH OTHER PERSON IS ENGAGED IN, INTENDS TO
ENGAGE IN OR HAS ANY ARRANGEMENT OR UNDERSTANDING WITH ANY PERSON TO PARTICIPATE
IN THE DISTRIBUTION OF SUCH EXCHANGE NOTES, (3) NEITHER THE HOLDER NOR ANY SUCH
OTHER PERSON IS AN "AFFILIATE" (AS DEFINED IN RULE 405 UNDER THE SECURITIES ACT)
OF THE COMPANY OR, IF IT IS AN AFFILIATE OF THE COMPANY, THAT IT WILL COMPLY
WITH THE APPLICABLE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF THE
SECURITIES ACT, AND (4) IF THE TENDERING HOLDER IS A BROKER OR DEALER (AS
DEFINED IN THE EXCHANGE ACT) (A) IT ACQUIRED THE OLD
 
                                       27
<PAGE>   34
 
NOTES FOR ITS OWN ACCOUNT AS A RESULT OF MARKET-MAKING ACTIVITIES OR OTHER
TRADING ACTIVITIES AND (B) IT HAS NOT ENTERED INTO ANY ARRANGEMENT OR
UNDERSTANDING WITH THE COMPANY OR ANY "AFFILIATE" THEREOF TO DISTRIBUTE THE
EXCHANGE NOTES TO BE RECEIVED IN THE EXCHANGE OFFER. IN THE CASE OF A
BROKER-DEALER THAT RECEIVES EXCHANGE NOTES FOR ITS OWN ACCOUNT IN EXCHANGE FOR
OLD NOTES WHICH WERE ACQUIRED BY IT AS A RESULT OF MARKET-MAKING OR OTHER
TRADING ACTIVITIES, THE LETTER OF TRANSMITTAL WILL ALSO INCLUDE AN
ACKNOWLEDGMENT THAT THE BROKER-DEALER WILL DELIVER A COPY OF THIS PROSPECTUS IN
CONNECTION WITH THE RESALE BY IT OF EXCHANGE NOTES RECEIVED PURSUANT TO THE
EXCHANGE OFFER; HOWEVER, BY SO ACKNOWLEDGING AND BY DELIVERING A PROSPECTUS,
SUCH HOLDER WILL NOT BE DEEMED TO ADMIT THAT IT IS AN "UNDERWRITER" WITHIN THE
MEANING OF THE SECURITIES ACT. SEE "PLAN OF DISTRIBUTION." IN CONNECTION WITH
THE OFFERING OF OLD NOTES, THE COMPANY AGREED TO FILE AND MAINTAIN, SUBJECT TO
CERTAIN LIMITATIONS, A REGISTRATION STATEMENT THAT WOULD ALLOW LEHMAN BROTHERS
INC. TO ENGAGE IN MARKET-MAKING TRANSACTIONS WITH RESPECT TO THE NOTES.
 
     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 HOLDERS. 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 ENSURE DELIVERY TO THE EXCHANGE AGENT PRIOR TO THE EXPIRATION DATE.
NO LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO THE COMPANY. HOLDERS MAY
ALSO REQUEST THAT THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST
COMPANIES OR NOMINEES EFFECT SUCH TENDER FOR HOLDERS, IN EACH CASE AS SET FORTH
HEREIN AND IN THE LETTER OF TRANSMITTAL.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of the 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 absolute right to waive 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 be
under any duty to give notification of defects or irregularities with respect to
tenders of Old Notes, nor shall any of them incur any liability for failure to
give such notification. Tenders of Old Notes will not be deemed to have been
made until such irregularities have been cured or waived. Any Old Notes received
by the Exchange Agent that the Company determines are not properly tendered or
the tender of which is otherwise rejected by the Company, and as to which the
defects or irregularities have not been cured or waived by the Company, will be
returned by the Exchange Agent to the tendering holder 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 (i) to
purchase or make offers for any Old Notes that remain outstanding subsequent to
the Expiration Date, or, as set forth under "-- Conditions of the Exchange
Offer," terminate the Exchange Offer and (ii) to the extent permitted by
applicable law, to purchase Old Notes in the open market, in privately
negotiated transactions or otherwise. The terms of any such purchases or offers
may differ from the terms of the Exchange Offer.
 
                                       28

BOOK-ENTRY TRANSFER
 
     The Company understands that the Exchange Agent will make a request
promptly after the date of this Prospectus to establish accounts with respect to
the Old Notes at the Depositary for the purpose of facilitating the Exchange
Offer, and subject to the establishment thereof, any financial institution that
is a participant in the Depositary's system may make book-entry delivery of Old
Notes by causing such Depositary to transfer such Old Notes into the Exchange
Agent's account with respect to the Old Notes in accordance with the
Depositary's procedures for such transfer. ALTHOUGH DELIVERY OF OLD NOTES MAY BE
EFFECTED THROUGH BOOK-ENTRY TRANSFER INTO THE EXCHANGE AGENT'S ACCOUNT AT THE
DTC, AN APPROPRIATE LETTER OF TRANSMITTAL PROPERLY COMPLETED AND DULY EXECUTED
WITH ANY REQUIRED SIGNATURE GUARANTEE AND ALL OTHER REQUIRED DOCUMENTS MUST IN
EACH CASE BE TRANSMITTED TO AND RECEIVED OR CONFIRMED BY THE EXCHANGE AGENT AT
ITS ADDRESS SET FORTH HEREIN ON OR PRIOR TO THE EXPIRATION DATE, OR, IF THE
GUARANTEED DELIVERY PROCEDURES DESCRIBED BELOW ARE COMPLIED WITH, WITHIN THE
TIME PERIOD PROVIDED UNDER SUCH PROCEDURES. DELIVERY OF DOCUMENTS TO THE BOOK-
ENTRY TRANSFER FACILITY DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT. All
references in the Prospectus to deposit or delivery of Old Notes shall be deemed
to include DTC's book-entry delivery method.
 
GUARANTEED DELIVERY PROCEDURES
 
     Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available, or (ii) who cannot deliver their Old Notes, the Letter of
Transmittal or any other required documents to the Exchange Agent prior to the
Expiration Date, or who cannot complete the procedure for book-entry transfer on
a timely basis, may effect a tender if:
 
          (a) the tender is made through an Eligible Institution;
 
          (b) prior to the Expiration Date, the Exchange Agent receives from
     such Eligible Institution a properly completed and duly executed Notice of
     Guaranteed Delivery (by facsimile transmittal, mail or hand delivery)
     setting forth the name and address of the holder, the certificate number or
     numbers of such holder's Old Notes and the principal amount of such 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 Expiration Date, the Letter of Transmittal (or facsimile
     thereof), together with the certificate(s) representing the Old Notes to be
     tendered in proper form for transfer (or confirmation of a book-entry
     transfer into the Exchange Agent's account at the Depositary of Old Notes
     delivered electronically) and any other documents required by the Letter of
     Transmittal, will be deposited by the Eligible Institution with the
     Exchange Agent; and
 
          (c) such properly completed and executed Letter of Transmittal (or
     facsimile thereof), together with the certificate(s) representing all
     tendered Old Notes in proper form for transfer (or confirmation of a
     book-entry transfer into the Exchange Agent's account at the Depositary of
     Old Notes delivered electronically) and all other documents required by the
     Letter of Transmittal are received by the Exchange Agent within three NYSE
     trading days after the Expiration Date.
 
     Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Old Notes according to the guaranteed
delivery procedures set forth above.
 
WITHDRAWAL OF TENDERS
 
     Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the business day before
the Expiration Date.
 
     For a withdrawal to be effective, a written or facsimile transmission
notice of withdrawal must be received by the Exchange Agent at its address set
forth herein prior to 5:00 p.m., New York City time, on the business
 
                                       29
<PAGE>   36
 
day before 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 or, in the
case of Old Notes transferred by book-entry transfer, the name and number of the
account at the Depositary to be credited), (iii) be signed by the Depositor in
the same manner as the original signature on the Letter of Transmittal, by which
such Old Notes were tendered (including any required signature guarantee) or be
accompanied by documents of transfer sufficient to permit the Trustee with
respect to the Old Notes to register the transfer of such Old Notes into the
name of the Depositor 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 withdrawal 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 purposes of the
Exchange Offer, and no Exchange Notes will be issued with respect thereto unless
the Old Notes so withdrawn are validly retendered. Any Old Notes that have been
tendered but are not accepted for exchange 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 described above under "-- Procedures for Tendering" at any time prior
to the Expiration Date.
 
CONDITIONS TO THE EXCHANGE OFFER
 
     Notwithstanding any other term of the Exchange Offer, the Company will not
be required to accept for exchange, or to issue Exchange Notes for, any Old
Notes, and may terminate the Exchange Offer before the acceptance of such Old
Notes if, in the Company's judgment, the Exchange Offer, or the making of any
exchange by a holder, violates applicable law or any applicable policy or
interpretation of the staff of the Commission.
 
     If the Company determines that it may terminate the Exchange Offer for any
of the reasons set forth above, the Company may (i) refuse to accept any Old
Notes and return any Old Notes that have been tendered to the holders thereof,
(ii) extend the Exchange Offer and retain all Old Notes tendered prior to the
Expiration Date of the Exchange Offer, subject to the rights of such holders of
tendered Old Notes to withdraw their tendered Old Notes or (iii) waive such
termination event with respect to the Exchange Offer and accept all properly
tendered Old Notes that have not been withdrawn. If such waiver constitutes a
material change in the Exchange Offer, the Company will disclose such change by
means of a supplement to this Prospectus that will be distributed to each
registered holder, and the Company will extend the Exchange Offer for a period
of five to ten business days, depending upon the significance of the waiver and
the manner of disclosure to the registered holders, if the Exchange Offer would
otherwise expire during such period.
 
EXCHANGE AGENT
 
     State Street Bank and Trust Company, the Trustee under the Indenture, has
been appointed as Exchange Agent for the Exchange Offer. In such capacity, the
Exchange Agent has no fiduciary duties and will be acting solely on the basis of
directions of the Company. Requests for assistance and requests for additional
copies of this Prospectus or of the Letter of Transmittal should be directed to
the Exchange Agent addressed as follows:

     DELIVERY OF THE LETTER OF TRANSMITTAL TO AN ADDRESS OTHER THAN AS SET FORTH
ABOVE OR TRANSMISSION OF INSTRUCTIONS VIA FACSIMILE OTHER THAN AS SET FORTH
ABOVE WILL NOT CONSTITUTE A VALID DELIVERY OF SUCH LETTER OF TRANSMITTAL.
 
SOLICITATION OF TENDERS; FEES AND EXPENSES
 
     The expenses of soliciting tenders pursuant to the Exchange Offer will be
borne by the Company. The principal solicitation pursuant to the Exchange Offer
is being made by mail. Additional solicitations may be made by officers and
regular employees of the Company and its affiliates in person, by telegraph,
telephone or telecopier.
 
     The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or other
persons soliciting acceptances of the Exchange Offer. The Company will, however,
pay the Exchange Agent reasonable and customary fees for its services, reimburse
the Exchange Agent for its reasonable out-of-pocket costs and expenses in
connection therewith and indemnify the Exchange Agent for all losses and claims
incurred by it as a result of the Exchange Offer. The Company may also pay
brokerage houses and other custodians, nominees and fiduciaries the reasonable
out-of-pocket expenses incurred by them in forwarding copies of this Prospectus,
the Letter of Transmittal and related documents to the beneficial owners of the
Old Notes and in handling or forwarding tenders for exchange.
 
     The expenses to be incurred in connection with the Exchange Offer,
including fees and expenses of the Exchange Agent and Trustee and accounting and
legal fees and printing costs, will be paid by the Company.
 
     The Company will pay all transfer taxes, if any, applicable to the exchange
of Old Notes pursuant to the Exchange Offer. If, however, certificates
representing Exchange Notes or Old Notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be registered or issued
in the name of, any person other than the registered holder of the Old Notes
tendered, or if tendered Old Notes are registered in the name of any person
other than the person signing the Letter of Transmittal, or if a transfer tax is
imposed for any reason other than the exchange of Old Notes pursuant to the
Exchange Offer, then the amount of any such transfer taxes (whether imposed on
the registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemption therefrom
is not submitted with the Letter of Transmittal, the amount of such transfer
taxes will be billed by the Company directly to such tendering holder.
 
ACCOUNTING TREATMENT
 
     The Exchange Notes will be recorded at the same carrying value as the Old
Notes, as reflected in the Company's accounting records on the date of the
exchange. Accordingly, no gain or loss for accounting purposes will be
recognized by the Company as a result of the consummation of the Exchange Offer.
The expenses of the Exchange Offer will be amortized by the Company over the
term of the Exchange Notes.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     Participation in the Exchange Offer is voluntary. Holders of the Old Notes
are urged to consult their financial and tax advisors in making their own
decisions as to what action to take.
 
     As a result of the making of, and upon acceptance for exchange of all
validly tendered Old Notes pursuant to the terms of, this Exchange Offer, the
Company will have fulfilled a covenant contained in the Registration Rights
Agreement. Holders of the Old Notes who do not tender their Old Notes in the
Exchange Offer will continue to hold such Old Notes and will be entitled to all
the rights, and subject to the limitations applicable thereto, under the
Indenture and the Registration Rights Agreement, except for any such rights
under the Registration Rights Agreement that by their terms terminate or cease
to have further effect as a result of the making of this Exchange Offer. See
"Description of the Notes." All untendered Old Notes will continue to be subject
to the restrictions on transfer set forth in the Indenture. The Old Notes may
not be offered, resold, pledged or otherwise transferred, except (i) to the
Company, (ii) pursuant to an effective
 
                                       31
<PAGE>   38
 
registration statement under the Securities Act, (iii) to Qualified
Institutional Buyers in reliance upon the exemption from the registration
requirements of the Securities Act provided by Rule 144A, (iv) in an offshore
transaction complying with Rule 903 or 904 of Regulation S under the Securities
Act, (v) pursuant to an exemption from registration under the Securities Act
provided by Rule 144 thereunder (if available) or (vi) in accordance with
another exemption from the registration requirements under the Securities Act
(and based upon an opinion of counsel) and, in each case, in accordance with any
applicable securities laws of any State of the United States or any other
applicable jurisdiction. To the extent that Old Notes are tendered and accepted
in the Exchange Offer, the liquidity of the trading market for untendered Old
Notes could be adversely affected.
 
     The Company may in the future seek to acquire untendered Old Notes in the
open market or through privately negotiated transactions, through subsequent
exchange offers or otherwise. The Company intends to make any such acquisitions
of Old Notes in accordance with the applicable requirements of the Exchange Act
and the rules and regulations of the Commission thereunder, including Rule
14e-1, to the extent applicable. The Company has no present plan to acquire any
Old Notes that are not tendered in the Exchange Offer or to file a registration
statement to permit resales of any Old Notes that are not tendered in the
Exchange Offer.

                       DESCRIPTION OF OTHER INDEBTEDNESS
 
     The following is a description of the principal terms of certain other
indebtedness of the Company:
 
NEW CREDIT FACILITY
 
     On June 8, 1998, the Company entered into the New Credit Facility with
Christiania Bank og Kreditkasse ASA ("CBK") as Administrative Agent and Arranger
and The Chase Manhattan Bank, London Branch ("Chase") as Security and
Documentation Agent and Arranger (CBK and Chase collectively are referred to as
the "Lenders"). The Company will be the borrower under Tranche 1 of the New
Credit Facility, and the Company and certain of its subsidiaries ("Subsidiary
Borrowers") will be the borrowers under Tranche 2. The following is a summary of
the material terms and conditions of the New Credit Facility and is subject to
the detailed provisions of the New Credit Facility agreements and documents
entered into in connection therewith.
 
     Loans; Interest Rates; Repayment. The New Credit Facility is structured as
a multicurrency revolving loan agreement, initially in an aggregate principal
amount of $50.0 million and potentially up to an aggregate principal amount of
$75.0 million, which is available in two tranches. The proceeds of the New
Credit Facility, together with proceeds of the Offering, provided the financing
to repay in full amounts owing at the time of the closing of the Offering under
the Company's then existing credit facilities and will provide financing for
future acquisitions, working capital and other general corporate purposes. See
"Prospectus Summary -- The Private Placement."
 
     Both Tranches will fully amortize over a period of five years. Thirty-nine
months after the closing of the New Credit Facility, and quarterly thereafter
for 8 quarters until maturity, the amount of each Tranche of the New Credit
Facility will be ratably reduced so that in the last quarter prior to maturity
of the New Credit Facility, the facility amount available in each Tranche will
be one-eighth of the original principal amount of each Tranche. Both Tranche 1
and Tranche 2 are revolving loans which may be borrowed, repaid and reborrowed
from time to time until five years after the closing of the New Credit Facility,
subject to certain customary conditions on the date of any such borrowing.
 
     Tranche 1, initially in the amount of $25.0 million, and potentially up to
$30.0 million, bears interest at LIBOR plus a margin ranging from 1.0% to 1.375%
per annum which margin will be determined by the Company's ratio of funded debt
to total capitalization ("Leverage Ratio"). Tranche 1 is available to the
Company for general corporate purposes. Tranche 2, initially in the amount of
$25.0 million and potentially up to $45.0 million, bears interest at LIBOR plus
a margin ranging from .80% to 1.25% per annum, which will be determined by the
Company's Leverage Ratio. Tranche 2 is available to finance acquisition of (i)
up to 50% of the acquisition cost of shares in companies operating within the
same industry as the Company ("Share Acquisition") or (ii) up to 65% of the
purchase price or cost of a vessel ("Vessel Acquisition").
 
     Security. The obligations under Tranche 1 of the New Credit Facility are
obligations of the Company as Borrower and are unsecured. The obligations under
Tranche 2 of the New Credit Facility are obligations of either the Company or
the Subsidiary Borrowers and are secured as described below. If the facility
amount available under Tranche 2 is used for a Share Acquisition, then the
Company or a Subsidiary Borrower, as the case may be, will be required to pledge
all of the stock acquired or, if the stock being acquired represents ownership
in a foreign subsidiary not taxable in the United States (a "Foreign
Subsidiary"), 66% of the stock of the Foreign Subsidiary will be required. If
any of the facility amount available under Tranche 2 is used for a Vessel
Acquisition, then the Company, or the Subsidiary Borrower, as applicable, shall
be required to grant the Lenders on the vessel(s) acquired: (i) a first priority
mortgage, (ii) an assignment of earnings and insurance and (iii) an assignment
of charters over one year.
 
     Guarantees. The obligations of the Company will be guaranteed by all
material Subsidiaries of the Company, excluding foreign Subsidiaries not taxable
in the United States. Initially, the obligations of the Company under the New
Credit Facility will not be guaranteed by any of the Company's Subsidiaries. The
obligations of Subsidiary Borrowers under Tranche 2 are guaranteed by the
Company.
 
     Prepayments. The Company is required to make prepayments on Tranche 2
borrowings in the event of a sale or loss of a vessel, (i) if secured by a
single vessel, in an amount equal to the amount advanced on such
 
                                       33
<PAGE>   40
 
vessel or (ii) if secured by multiple vessels, the prepayment shall be in an
amount which corresponds to the ratio of the fair market value of the sold or
lost vessel divided by the aggregate fair market value of all vessels secured by
the advance. The Company is required to make a prepayment on a Tranche 2
borrowing for a Share Acquisition upon the sale of the shares in proportion to
the shares sold.
 
     Conditions and Covenants. The obligations of the Lenders under the New
Credit Facility are subject to the satisfaction of certain conditions precedent
customary in similar credit facilities or otherwise appropriate under the
circumstances. The Company and each of its Subsidiaries are subject to certain
negative covenants contained in the New Credit Facility, including without
limitation covenants that restrict, subject to specified exceptions: (i) the
incurrence of additional indebtedness and other obligations, (ii) the granting
of any liens on the current or future assets of the Company or any of its
Subsidiaries, (iii) dispositions of assets, and (iv) dividends by the Company.
The New Credit Facility also contains customary affirmative covenants, including
compliance with environmental laws, reimbursement of increased costs of lenders,
financial reporting and the pledge of additional collateral under certain
circumstances. In addition, the New Credit Facility requires the Company to
maintain compliance with certain specified financial covenants including the
Leverage Ratio, a minimum interest coverage ratio, and a minimum net worth.
Certain of these financial, negative and affirmative covenants are more
restrictive than those set forth in the Indenture.
 
     Events of Default. The New Credit Facility also includes events of default
that are typical for senior credit facilities, including without limitation,
nonpayment of principal, interest, or fees; violation of covenants; inaccuracy
of representations and warranties in any material respect; cross default to
certain other indebtedness and agreements; bankruptcy and insolvency events;
material judgments and liabilities; defaults and change of control. The
occurrence of any of such events of default could result in acceleration of the
Company's obligations under the New Credit Facility and foreclosure on any
collateral securing such obligations, which could have material adverse results
to the holders of the Notes.
 
     As of June 30, 1998, the Company had no Indebtedness outstanding under the
New Credit Facility.

                            DESCRIPTION OF THE NOTES
 
GENERAL
 
     The Exchange Notes will be issued, and the Old Notes were issued, pursuant
to an Indenture (the "Indenture") among the Company and State Street Bank and
Trust Company, as trustee (the "Trustee") dated as of June 8, 1998. References
to the Notes include the Old Notes and the Exchange Notes unless the context
indicates otherwise. 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 (the "Trust Indenture Act"). The Notes are subject to all
such terms, and Holders of Notes are referred to the Indenture and the Trust
Indenture Act for a statement thereof. The following summary of the provisions
of the Indenture does not purport to be complete and is qualified in its
entirety by reference to the Indenture, including the definitions therein of
certain terms used below. Copies of the Indenture are available as set forth
below under "-- Additional Information." The definitions of certain terms used
in the following summary are set forth below under "-- Certain Definitions." For
purposes of this summary, the term "Company" refers only to GulfMark Offshore,
Inc. and not to any of its Subsidiaries.
 
     The Notes are general unsecured obligations of the Company ranking pari
passu in right of payment with all current or future senior Indebtedness of the
Company, including borrowings under the Credit Facility, and senior in the right
of payment to all Subordinated Indebtedness of the Company issued in the future,
if any. The Company is a holding company that conducts substantially all of its
operations through its direct and indirect U.S. and foreign subsidiaries, and
substantially all of the Company's assets consist of equity in its direct
subsidiaries. The Notes are not guaranteed as of the Issue Date by any
Subsidiaries of the Company. The Indenture provides that the Notes will be
guaranteed by any existing or future Subsidiary of the Company that guarantees
any Indebtedness of the Company. As of March 31, 1998, on a pro forma basis
after giving effect to the Offering and the application of the net proceeds
therefrom, and excluding borrowings that are available under the New Credit
Facility, the Company (exclusive of its Subsidiaries) would have had no
Indebtedness outstanding other than the Notes, and the Company's Subsidiaries
would have had Indebtedness of $0.6 million outstanding. The Indenture limits,
subject to certain financial tests and exceptions, the amount of additional
Indebtedness that the Company and its Restricted Subsidiaries may incur. See
"-- Certain Covenants -- Incurrence of Indebtedness and Issuance of Preferred
Stock."
 
     As of the Issue Date, all of the Company's Subsidiaries will be Restricted
Subsidiaries. Under certain circumstances, the Company will be able to designate
current or future Subsidiaries as Unrestricted Subsidiaries. Unrestricted
Subsidiaries will not be subject to any of the restrictive covenants set forth
in the Indenture.
 
PRINCIPAL, MATURITY AND INTEREST
 
     The Notes will be limited in aggregate principal amount to $200 million,
$130 million of which were issued in the Offering, and will mature on June 1,
2008. Additional amounts may be issued after the date of the Indenture in one or
more series from time to time subject to the limitations set forth under the
caption "-- Certain Covenants -- Incurrence of Indebtedness and Issuance of
Preferred Stock" and restrictions contained in any Credit Facility, including
the New Credit Facility, and any other agreement to which the Company is a party
at the time of such issuance. The Company has agreed not to offer, issue or sell
any notes, bonds or other amounts under the Indenture other than the $130
million of Notes offered in the Offering and the Exchange Notes for a period of
180 days from the date of the Indenture without the prior written consent of
Lehman Brothers. Interest on the Notes will accrue at the rate of 8 3/4% per
annum and will be payable semi-annually in arrears on each June 1 and December
1, commencing on December 1, 1998, to Holders of record on the immediately
preceding May 15 and November 15. Interest on the Notes will accrue from the
most recent date to which interest and, in the case of the Old Notes only,
Liquidated Damages, if any, has been paid or, if no interest has been paid, from
the date of original issuance. Interest will be computed on the basis of a
360-day year comprised of twelve 30-day months. Principal, premium, if any, and
interest and, in the case of the Old Notes only, Liquidated Damages, if any, on
the Notes will be payable at the office or agency of the Company maintained for
such purpose within the City and State of New York or, at the option of the
                                       35
<PAGE>   42
 
Company, payment of interest and, in the case of the Old Notes only, Liquidated
Damages, if any, may be made by check mailed to the Holders of the Notes at
their respective addresses set forth in the register of Holders of Notes;
provided that all payments with respect to Notes the Holders of which have given
wire transfer instructions to the Company will be required to be made by wire
transfer of immediately available funds to the accounts specified by the Holders
thereof. Until otherwise designated by the Company, the Company's office or
agency in New York will be the office of the Trustee maintained for such
purpose. The Notes will be issued in denominations of $1,000 and integral
multiples thereof.
 
SUBSIDIARY GUARANTEES
 
     As of the Issue Date the Company's payment obligations under the Notes were
not guaranteed by any of the Company's Subsidiaries. The Indenture provides that
if any Subsidiary of the Company, after the Issue Date, guarantees any
Indebtedness of the Company, including Indebtedness under any credit facility,
then such Subsidiary shall (i) execute a supplemental indenture in form and
substance satisfactory to the Trustee providing that such Subsidiary shall
become a Guarantor under the Indenture and (ii) deliver an opinion of counsel to
the effect that such supplemental indenture has been duly authorized and
executed by such Subsidiary. In the event a Subsidiary becomes a Guarantor in
the future, the obligations of such Guarantor under its Subsidiary Guarantee
will be a general unsecured obligation of the Guarantor ranking pari passu in
right of payment with all other current or future senior Indebtedness of such
Guarantor, and senior in the right of payment to any Subordinated Indebtedness
of such Guarantor. The obligations of each Guarantor under any future Subsidiary
Guarantee will be limited to the maximum amount the Guarantors are permitted to
guarantee under applicable law without creating a "fraudulent conveyance." See
"Risk Factors -- Fraudulent Conveyance Considerations."
 
     The Indenture provides that no Guarantor may consolidate with or merge with
or into (whether or not such Guarantor is the surviving Person) another Person
whether or not affiliated with such Guarantor unless (i) subject to the
provisions of the following paragraph, the Person formed by or surviving any
such consolidation or merger (if other than such Guarantor) assumes all the
obligations of such Guarantor pursuant to a supplemental indenture in form and
substance reasonably satisfactory to the Trustee, under the Notes and the
Indenture; (ii) immediately after giving effect to such transaction, no Default
or Event of Default exists; (iii) such Guarantor, or any Person formed by or
surviving any such consolidation or merger, would have Consolidated Net Worth
(immediately after giving effect to such transaction) equal to or greater than
the Consolidated Net Worth of such Guarantor immediately preceding the
transaction; and (iv) the Company would be permitted by virtue of the Company's
pro forma Fixed Charge Coverage Ratio, immediately after giving effect to such
transaction, to incur at least $1.00 of additional Indebtedness pursuant to the
Fixed Charge Coverage Ratio test set forth in the first paragraph of the
covenant described above under the caption "-- Certain Covenants -- Incurrence
of Indebtedness and Issuance of Preferred Stock."
 
     Notwithstanding the foregoing paragraph, (i) any Guarantor may consolidate
with, merge into or transfer all or a part of its properties and assets to the
Company or any other Guarantor and (ii) any Guarantor may merge with a Wholly
Owned Restricted Subsidiary of the Company that has no significant assets or
liabilities and was incorporated solely for purpose of reincorporating or
redomesticating such Guarantor in another State of the United States or, if such
Guarantor was organized under the laws of a jurisdiction other than a State of
the United States, in any foreign country that is a member of the Organization
for Economic Cooperation and Development; provided that, in each case, such
merged entity continues to be a Guarantor.
 
     The Indenture provides that upon (i) the release by the lenders under all
Indebtedness of the Company of all guarantees of a Guarantor and all Liens on
the property and assets of such Guarantor relating to such Indebtedness, or (ii)
a sale or other disposition of all of the assets of any Guarantor, by way of
merger, consolidation or otherwise, or a sale or other disposition of all of the
capital stock of any Guarantor in compliance with the Indenture to any entity
that is not the Company or a Subsidiary, then such Guarantor (in the event of a
sale or other disposition, by way of such a merger, consolidation or otherwise,
of all of the capital stock of such Guarantor), or the Person acquiring the
property (in the event of such a sale or other disposition of all of the assets
of such Guarantor), will be released and relieved of any obligations under its
Subsidiary Guarantee; provided, however, that any such termination shall occur
only to the extent that all obligations of
                                       36
<PAGE>   43
 
such Guarantor under such Indebtedness and all of its guarantees of, and under
all of its pledges of assets or other security interests which secure,
Indebtedness of the Company shall also terminate upon such release, sale or
transfer and, in the event of any sale or other disposition, that the Net
Proceeds of such sale or other disposition are applied in accordance with the
applicable provisions of the Indenture. See "-- Repurchase at the Option of
Holders -- Asset Sales."
 
OPTIONAL REDEMPTION
 
     The Notes are not redeemable at the Company's option prior to June 1, 2003.
Thereafter, the Notes are subject to redemption at any time at the option of the
Company, in whole or in part, upon not less than 30 nor more than 60 days'
notice, at the redemption prices (expressed as percentages of principal amount)
set forth below plus accrued and unpaid interest and, in the case of the Old
Notes only, Liquidated Damages, if any, thereon to the applicable redemption
date, if redeemed during the twelve-month period beginning on June 1 of the
years indicated below:
 
<TABLE>
<CAPTION>
                       YEAR                         PERCENTAGE
                       ----                         ----------

2005..............................................   101.458%
2006 and thereafter...............................   100.000%
</TABLE>
 
     Notwithstanding the foregoing, at any time before June 1, 2001, the Company
may on any one or more occasions redeem up to an aggregate of 35% of the
principal amount of Notes outstanding at a redemption price of 108.75% of the
principal amount thereof, plus accrued and unpaid interest, if any, and, in the
case of the Old Notes only, Liquidated Damages, if any, thereon, to the
redemption date, with the net cash proceeds of any Public Equity Offering;
provided that at least 65% of the aggregate principal amount of Notes
outstanding on the Issue Date remain outstanding immediately after each
occurrence of such redemption; and provided, further, that each such redemption
shall occur within 60 days of the date of the closing of such Public Equity
Offering.
 
SELECTION AND NOTICE
 
     If less than all of the Notes are to be redeemed at any time, selection of
Notes for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed, or, if the Notes are not so listed, on a pro rata basis, by
lot or by such method as the Trustee shall deem fair and appropriate; provided
that no Notes of $1,000 or less shall be redeemed in part. Notices of redemption
shall be mailed by first class mail at least 30 but not more than 60 days before
the redemption date to each Holder of Notes to be redeemed at its registered
address. Notices of redemption may not be conditional. If any Note is to be
redeemed in part only, the notice of redemption that relates 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. Notes called
for redemption become due on the date fixed for redemption. On and after the
redemption date, interest and, in the case of the Old Notes only, Liquidated
Damages, if any, cease to accrue on Notes or portions of them called for
redemption.
 
MANDATORY REDEMPTION
 
     Except as set forth below under "-- Repurchase at the Option of Holders,"
the Company is not required to make mandatory redemption or sinking fund
payments with respect to the Notes.
 
REPURCHASE AT THE OPTION OF HOLDERS
 
     Change of Control. Upon the occurrence of a Change of Control, each Holder
of Notes will have the right to require the Company to repurchase all or any
part (equal to $1,000 or an integral multiple thereof) of such Holder's Notes
pursuant to the offer described below (the "Change of Control Offer") at an
offer price
 
                                       37
<PAGE>   44
 
in cash equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest and, in the case of the Old Notes only, Liquidated Damages, if
any, thereon, to the date of purchase (the "Change of Control Payment"). Within
30 days following any Change of Control, the Company will mail a notice to each
Holder describing the transaction or transactions that constitute the Change of
Control and offering to repurchase Notes on the date specified in such notice,
which date shall be no earlier than 30 days and no later than 60 days from the
date such notice is mailed (the "Change of Control Payment Date"), pursuant to
the procedures required by the Indenture and described in such notice. The
Company will comply with the requirements of Rule 14e-1 under the Exchange Act
and any other securities laws and regulations thereunder to the extent such laws
and regulations are applicable in connection with the repurchase of the Notes as
a result of a Change of Control.
 
     On the Change of Control Payment Date, the Company will, to the extent
lawful, (i) accept for payment all Notes or portions thereof properly tendered
pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all Notes or
portions thereof so tendered and (iii) deliver or cause to be delivered to the
Trustee the Notes so accepted together with an Officers' Certificate stating the
aggregate principal amount of Notes or portions thereof being purchased by the
Company. The Paying Agent will promptly mail to each Holder of Notes so tendered
the Change of Control Payment for such Notes, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each Holder
a new Note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any; provided that each such new Note will be in a principal
amount of $1,000 or an integral multiple thereof. The Indenture will provide
that, prior to complying with the provisions of this covenant, but in any event
within 90 days following a Change of Control, the Company will either repay all
outstanding Indebtedness or obtain the requisite consents, if any, under all
agreements governing outstanding Indebtedness to permit the repurchase of Notes
required by this covenant. The Company will publicly announce the results of the
Change of Control Offer on or as soon as practicable after the Change of Control
Payment Date.
 
     The Change of Control provisions described above will be applicable whether
or not any other provisions of the Indenture are applicable. Except as described
above with respect to a Change of Control, the Indenture does not contain
provisions that permit the Holders of the Notes to require that the Company
repurchase or redeem the Notes in the event of a takeover, recapitalization or
similar transaction. The definition of Change of Control includes a phrase
relating to the sale, lease, transfer, conveyance or other disposition of "all
or substantially all" of the assets of the Company. There is little case law
interpreting the phrase "all or substantially all" in the context of an
indenture. Because there is no precise established definition of this phrase,
the ability of a holder of Notes to require the Company to repurchase such Notes
as a result of a sale, lease, exchange or other transfer of all or substantially
all of the Company's assets to a Person or a Group may be uncertain.
 
     The Credit Facility limits the ability of the Company to purchase any Notes
and provides that certain change of control events with respect to the Company
would constitute a default thereunder. Any future Credit Facilities or other
agreements relating to Indebtedness to which the Company becomes a party may
contain similar restrictions and provisions. In the event a Change of Control
occurs at a time when the Company is prohibited from purchasing Notes, the
Company could seek the consent of its lenders to the purchase of Notes or could
attempt to refinance the borrowings that contain such prohibition. If the
Company does not obtain such a consent or repay such borrowings, the Company
will remain prohibited from purchasing Notes. In such case, the Company's
failure to purchase tendered Notes would constitute an Event of Default under
the Indenture which would, in turn, constitute a default under the Credit
Facility. In such circumstances, the subordination provisions in the Indenture
would likely restrict payments to the Holders of Notes.
 
     The Company will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in the Indenture applicable to a Change of Control Offer made by the Company and
purchases all Notes validly tendered and not withdrawn under such Change of
Control Offer.
 
                                       38
<PAGE>   45
 
     Asset Sales. The Indenture provides that the Company will not, and will not
permit any of its Restricted Subsidiaries to, engage in an Asset Sale unless (i)
the Company or such Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the fair market
value (which shall be determined in good faith by the Company's Board of
Directors) of the assets or Equity Interests issued or sold or otherwise
disposed of and (ii) at least 75% of the consideration therefor received by the
Company or such Restricted Subsidiary is in the form of cash or Cash
Equivalents; provided that the amount of (x) any liabilities (as shown on the
Company's or such Restricted Subsidiary's most recent balance sheet), of the
Company or any Restricted Subsidiary of the Company (other than contingent
liabilities and liabilities that are by their terms subordinated to the Notes or
any Subsidiary Guarantee) that are assumed by the transferee of any such assets
pursuant to a customary novation agreement that releases the Company or such
Restricted Subsidiary from further liability and (y) any securities, notes or
other obligations received by the Company or any such Restricted Subsidiary from
such transferee that are immediately converted by the Company or such Restricted
Subsidiary into cash (to the extent of the cash received), shall be deemed to be
cash for purposes of this provision and provided, further, that any Asset Sale
pursuant to a condemnation, appropriation or other similar taking, including by
deed in lieu of condemnation, or pursuant to the foreclosure or other
enforcement of a Permitted Lien or exercise by the related lienholder of rights
with respect thereto, including by deed or assignment in lieu of foreclosure
shall not be required to satisfy the conditions set forth in clauses (i) and
(ii) of this paragraph.
 
     Within 270 days after the receipt of any Net Proceeds from an Asset Sale,
the Company or such Restricted Subsidiary, as the case may be, may apply such
Net Proceeds, at its option, (a) to permanently repay Indebtedness for borrowed
money other than Subordinated Indebtedness (and to correspondingly permanently
reduce the commitments with respect thereto in the case of revolving
borrowings), (b) to acquire a controlling interest in another business or all or
substantially all of the assets of a business, engaged in a Permitted Business,
or (c) to acquire other non-current assets to be used in a Permitted Business,
provided that the Company or such Restricted Subsidiary will have complied with
clause (b) or (c) if, within 270 days of such Asset Sale, the Company or such
Restricted Subsidiary shall have commenced and not completed or abandoned an
investment in compliance with clause (b) or (c) and such Investment is
substantially completed within 90 days after the first anniversary of such Asset
Sale. Pending the final application of any such Net Proceeds, the Company may
temporarily reduce Indebtedness under any Credit Facility or otherwise invest
such Net Proceeds in any manner that is not prohibited by the Indenture. Any Net
Proceeds from Asset Sales that are not applied or invested as provided in the
first sentence of this paragraph shall be deemed to constitute "Excess
Proceeds." When the aggregate amount of Excess Proceeds exceeds $10 million, the
Company shall be required to make an offer to all Holders of Notes and other
Indebtedness that ranks by its terms pari passu in right of payment with the
Notes and the terms of which contain substantially similar requirements with
respect to the application of net proceeds from asset sales as are contained in
the Indenture (an "Asset Sale Offer") to purchase on a pro rata basis the
maximum principal amount of the Notes, that is an integral multiple of $1,000,
that may be purchased out of the Excess Proceeds, at an offer price in cash in
an amount equal to 100% of the principal amount thereof plus accrued and unpaid
interest and, in the case of Old Notes only, Liquidated Damages, if any, to the
date of purchase, in accordance with the procedures set forth in the Indenture.
To the extent that the aggregate amount of Notes and other such Indebtedness
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Company may use any remaining Excess Proceeds for general corporate purposes. If
the aggregate principal amount of Notes surrendered by Holders thereof exceeds
the amount of Excess Proceeds, the Trustee shall select the Notes to be
purchased on a pro rata basis. Upon completion of such offer to purchase, the
amount of Excess Proceeds shall be reset at zero.
 
CERTAIN COVENANTS
 
     Restricted Payments. The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly: (i) declare or pay any
dividend or make any other payment or distribution on account of the Company's
or any of its Restricted Subsidiaries' Equity Interests (including, without
limitation, any payment in connection with any merger or consolidation involving
the Company) or to the direct or indirect holders of the Company's or any of its
Restricted Subsidiaries' Equity Interests in their capacity as such
                                       39
<PAGE>   46
 
(other than dividends or distributions payable in Equity Interests (other than
Disqualified Stock) of the Company); (ii) purchase, redeem or otherwise acquire
or retire for value (including without limitation, in connection with any merger
or consolidation involving the Company) any Equity Interests of the Company
(other than any such Equity Interests owned by a Wholly Owned Restricted
Subsidiary of the Company); (iii) make any payment on or with respect to, or
purchase, redeem, defease or otherwise acquire or retire for value any
Indebtedness that is subordinated to the Notes, except a payment of interest or
principal at Stated Maturity; or (iv) make any Restricted Investment (all such
payments and other actions set forth in clauses (i) through (iv) above being
collectively referred to as "Restricted Payments"), unless, at the time of and
after giving effect to such Restricted Payment:
 
          (a) no Default or Event of Default shall have occurred and be
     continuing or would occur as a consequence thereof; and
 
          (b) the Company would, at the time of such Restricted Payment and
     after giving pro forma effect thereto as if such Restricted Payment had
     been made at the beginning of the applicable four-quarter period, have been
     permitted to incur at least $1.00 of additional Indebtedness pursuant to
     the Fixed Charge Coverage Ratio test set forth in the first paragraph of
     the covenant described below under the caption "-- Incurrence of
     Indebtedness and Issuance of Preferred Stock"; and
 
          (c) such Restricted Payment, together with the aggregate amount of all
     other Restricted Payments made by the Company or any of its Restricted
     Subsidiaries after the Issue Date (excluding Restricted Payments permitted
     by clauses (ii), (iii), (iv), (v), (vi) or (vii) of the next succeeding
     paragraph), is less than the sum of (i) 50% of the Consolidated Net Income
     of the Company for the period (taken as one accounting period) from the
     beginning of the first fiscal quarter immediately following the Issue Date
     to the end of the Company's most recently ended fiscal quarter for which
     internal financial statements are available at the time of such Restricted
     Payment (or, if such Consolidated Net Income for such period is a deficit,
     less 100% of such deficit), plus (ii) 100% of the aggregate net proceeds
     received by the Company (including the fair market value of non-cash
     proceeds as determined in good faith by the Board of Directors of the
     Company less issuance costs) from the issue or sale, in either case, since
     the Issue Date of (A) Equity Interests of the Company (other than
     Disqualified Stock), or (B) Disqualified Stock or debt securities of the
     Company that have been converted into such Equity Interests (other than
     Equity Interests (or Disqualified Stock or convertible or exchangeable debt
     securities) sold to a Restricted Subsidiary of the Company and other than
     Disqualified Stock or debt securities that have been converted or exchanged
     into Disqualified Stock), plus (iii) in case any Unrestricted Subsidiary
     has been redesignated a Restricted Subsidiary pursuant to the terms of the
     Indenture or has been merged, consolidated or amalgamated with or into, or
     transfers or conveys assets to or is liquidated into, the Company or a
     Restricted Subsidiary and provided that no Default or Event of Default
     shall have occurred and be continuing or would occur as a consequence
     thereof, the lesser of (A) the book value (determined in accordance with
     GAAP) at the date of such redesignation, combination or transfer of the
     aggregate Investments made by the Company and its Restricted Subsidiaries
     in such Unrestricted Subsidiary (or of the assets transferred or conveyed,
     as applicable) and (B) the fair market value of such Investment in such
     Unrestricted Subsidiary at the time of such redesignation, combination or
     transfer (or of the assets transferred or conveyed, as applicable), in each
     case as determined in good faith by the Board of Directors of the Company,
     whose determination shall be conclusive and evidenced by a resolution of
     such Board and, in each case, after deducting any Indebtedness associated
     with the Unrestricted Subsidiary so designated or combined or with the
     assets so transferred or conveyed, plus (iv) to the extent not already
     included in Consolidated Net Income for such period, without duplication,
     any Restricted Investment that was made after the Issue Date is sold for
     cash or otherwise liquidated or repaid for cash, the lesser of (A) the cash
     return of capital with respect to such Restricted Investment (less the cost
     of disposition, if any) and (B) the initial amount of such Restricted
     Investment, plus (v) $10 million.
 
     The foregoing provisions shall not prohibit (i) the payment of any dividend
within 60 days after the date of declaration thereof, if at said date of
declaration such payment would have complied with the provisions of the
Indenture; (ii) the redemption, repurchase, retirement, defeasance or other
acquisition of any Indebted-
 
                                       40

ness which is subordinated to the Notes or Equity Interests of the Company in
exchange for, or out of the net cash proceeds of the substantially concurrent
sale (other than to a Restricted Subsidiary of the Company) of, Equity Interests
of the Company (other than any Disqualified Stock); provided that the amount of
any such net cash proceeds that are utilized for any such redemption,
repurchase, retirement, defeasance or other acquisition shall be excluded from
clause (c)(ii) of the preceding paragraph; (iii) the defeasance, redemption,
repurchase or other acquisition of Indebtedness which is subordinated to the
Notes with the net cash proceeds from an incurrence of Permitted Refinancing
Indebtedness; (iv) the payment of any dividend or distribution by a Restricted
Subsidiary of the Company to the holders of its common Equity Interests on a pro
rata basis; (v) the repurchase, redemption or other acquisition or retirement
for value of any Equity Interests of the Company or any Restricted Subsidiary of
the Company held by any employee or director of the Company (or any of its
Subsidiaries), or any former employee or director of the Company (or any of its
Subsidiaries) issued pursuant to any management equity plan or stock option plan
or any other management or employee benefit plan, agreement or trust; provided,
however, that the aggregate price paid for all such repurchased, redeemed,
acquired or retired Equity Interests pursuant to this clause (v) shall not
exceed $1 million in any twelve-month period; (vi) repurchases of Equity
Interests deemed to occur upon the cashless exercise of stock options; and (vii)
reasonable and customary directors' fees to the members of the Company's Board
of Directors, provided that such fees are consistent with past practice,
provided, further, that, with respect to clauses (ii), (iii), (v), (vi) and
(vii) above, no Default or Event of Default shall have occurred and be
continuing immediately after such transaction.
 
     In determining whether any Restricted Payment is permitted by the foregoing
covenant, the Company may allocate or reallocate all or any portion of such
Restricted Payment among the clauses (i) through (vii) of the preceding
paragraph or among such clauses and the first paragraph of this covenant
including clauses (a), (b) and (c), provided that at the time of such allocation
or reallocation, all such Restricted Payments, or allocated portions thereof,
would be permitted under the various provisions of the foregoing covenant.
 
     The amount of all Restricted Payments (other than cash) shall be the Fair
Market Value (as evidenced by a resolution of the Board of Directors of the
Company set forth in an Officers' Certificate delivered to the Trustee) on the
date of the Restricted Payment of the asset(s) or securities proposed to be
transferred or issued by the Company or such Restricted Subsidiary, as the case
may be, pursuant to the Restricted Payment, such determination to be based upon
an opinion or appraisal by an Independent Financial Advisor if the fair market
value of any Restricted Payment is greater than $10 million. Not later than (i)
the end of any calendar quarter in which any Restricted Payment is made or (ii)
the making of a Restricted Payment which, when added to the sum of all previous
Restricted Payments made in a calendar quarter, would cause the aggregate of all
Restricted Payments made in such quarter to exceed $5 million, the Company shall
deliver to the Trustee an Officers' Certificate stating that such Restricted
Payment is permitted and setting forth the basis upon which the calculations
required by this covenant were computed, which calculations may be based upon
the Company's latest available financial statements.
 
     The Board of Directors may designate any Unrestricted Subsidiary to be a
Restricted Subsidiary only if (i) immediately after giving effect to such
designation, the Company is able to incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test under the first
paragraph of the covenant described below under the caption "-- Incurrence of
Indebtedness and Issuance of Preferred Stock", (ii) immediately before and
immediately after giving effect to such designation, no Default or Event of
Default shall have occurred and be continuing and (iii) the Company certifies
that such designation complies with this covenant. Any such designation by the
Board of Directors shall be evidenced to the Trustee by promptly filing with the
Trustee a copy of the resolution giving effect to such designation and an
Officers' Certificate certifying that such designation complied with the
foregoing provisions. Notwithstanding the foregoing, if, at any time, any
Unrestricted Subsidiary would fail to meet the requirements under the definition
of Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted
Subsidiary for purposes of the Indenture and any Indebtedness of such Subsidiary
shall be deemed to be incurred as of such date.
 
     For purposes of making the determination as to whether such designation
would cause a Default or Event of Default, all outstanding Investments by the
Company and its Restricted Subsidiaries (except to the extent
                                       41
<PAGE>   48
 
repaid in cash) in the Subsidiary so designated will be deemed to be Restricted
Payments at the time of such designation and will reduce the amount available
for Restricted Payments under the first paragraph of this covenant. All such
outstanding Investments will be deemed to constitute Investments in an amount
equal to the greatest of (i) the net book value (determined in accordance with
GAAP) of such Investments at the time of such designation, (ii) the fair market
value of such Investments at the time of such designation and (iii) the original
fair market value of such Investments at the time they were made. Such
designation will only be permitted if such Restricted Payment would be permitted
at such time and if such Restricted Subsidiary otherwise meets the definition of
an Unrestricted Subsidiary.
 
     Incurrence of Indebtedness and Issuance of Preferred Stock. The Indenture
provides that the Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "incur") any Indebtedness (including Acquired
Debt) and that the Company shall not issue any Disqualified Stock and shall not
permit any of its Restricted Subsidiaries to issue any shares of preferred
stock; provided, however, that (a) the Company and any Guarantor may incur
Indebtedness (including Acquired Debt), (b) the Company may issue shares of
Disqualified Stock or (c) a Restricted Subsidiary may incur Acquired Debt, if,
in each case, the Company's Fixed Charge Coverage Ratio for the Company's most
recently ended four full fiscal quarters for which internal financial statements
are available immediately preceding the date on which such additional
Indebtedness is incurred or such Disqualified Stock is issued would have been at
least 2.25 to 1, determined on a pro forma basis (including a pro forma
application of the net proceeds therefrom), as if the additional Indebtedness
had been incurred, or the Disqualified Stock had been issued, as the case may
be, at the beginning of such four-quarter period.
 
     The provisions of the first paragraph of this covenant shall not apply to
the incurrence of any of the following items of Indebtedness (collectively,
"Permitted Debt"):
 
          (i) the incurrence by the Company and the Guarantors of Indebtedness
     represented by the Notes and the Subsidiary Guarantees;
 
          (ii) the incurrence by the Company of Indebtedness and letters of
     credit pursuant to any Credit Facility (with letters of credit being deemed
     to have a principal amount equal to the maximum potential liability of the
     Company thereunder) in an aggregate principal amount not to exceed $75.0
     million, less the sum of (a) the amount of Purchase Money Indebtedness
     incurred by the Company or any of its Restricted Subsidiaries under clause
     (vi) below and outstanding and (b) the aggregate amount of all proceeds of
     Assets Sales that have been applied since the Issue Date to permanently
     reduce the outstanding amount of such Indebtedness pursuant to the covenant
     described above under the caption "-- Repurchase at the Option of
     Holders -- Asset Sales";
 
          (iii) the incurrence by the Company or any of its Restricted
     Subsidiaries of Existing Indebtedness;
 
          (iv) the incurrence by the Company or any of its Restricted
     Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
     net proceeds of which are used to extend, refinance, renew, replace,
     defease or refund, Indebtedness that was permitted by the Indenture to be
     incurred;
 
          (v) the incurrence by the Company or any of its Restricted
     Subsidiaries of intercompany Indebtedness between or among the Company and
     any of its Restricted Subsidiaries; provided, however, that (i) if the
     Company or any Guarantor is the obligor on such Indebtedness, such
     Indebtedness is expressly subordinate to the payment in full of all
     Obligations with respect to the Notes and (ii) (A) any subsequent issuance
     or transfer of Equity Interests that results in any such Indebtedness being
     held by a Person other than the Company or a Restricted Subsidiary and (B)
     any sale or other transfer of any such Indebtedness to a Person that is not
     either the Company or a Restricted Subsidiary shall be deemed, in each
     case, to constitute an incurrence of such Indebtedness by the Company or
     such Restricted Subsidiary, as the case may be;
 
          (vi) the incurrence by the Company or any of its Restricted
     Subsidiaries of Purchase Money Indebtedness, in an aggregate principal
     amount (or amount of Capital Lease Obligation), including all
 
                                       42
<PAGE>   49
 
     Permitted Refinancing Indebtedness incurred to refund, refinance or replace
     Purchase Money Indebtedness incurred pursuant to this clause (vi), not to
     exceed $45.0 million at any time outstanding.
 
          (vii) the incurrence by the Company or any of its Restricted
     Subsidiaries of obligations in the ordinary course of business under (A)
     trade letters of credit which are to be repaid in full not more than one
     year after the date on which such Indebtedness is originally incurred to
     finance the purchase of goods by the Company or a Restricted Subsidiary of
     the Company; (B) standby letters of credit issued for the purpose of
     supporting (1) workers' compensation liabilities of the Company or any of
     its Restricted Subsidiaries, or (2) performance, payment, deposit or surety
     obligations of the Company or any of its Restricted Subsidiaries; and (C)
     bid, advance payment and performance bonds and surety bonds of the Company
     and its Restricted Subsidiaries, and refinancings thereof;
 
          (viii) the incurrence by the Company or any of its Restricted
     Subsidiaries of (x) Financial Hedging Obligations that are incurred for the
     purpose of fixing or hedging interest rate risk (including with respect to
     any floating rate Indebtedness that is permitted by the terms of the
     Indenture to be outstanding), but only to the extent such obligations do
     not exceed 105% of the aggregate principal amount of the Indebtedness to
     which such obligations relate, and (y) Currency Hedging Obligations in
     connection with the conduct of the Permitted Business in currencies other
     than the United States Dollar, and, in the case of each of clauses (x) and
     (y) not for speculative purposes and incurred in the ordinary course of
     business consistent with prudent business practices;
 
          (ix) the guarantee by the Company or any Restricted Subsidiary of the
     Company of Indebtedness of the Company or a Restricted Subsidiary of the
     Company that was permitted to be incurred by another provision of this
     covenant; provided, that the guarantee of any Indebtedness under this
     clause (ix) by a Restricted Subsidiary of the Company that ceases to be a
     Restricted Subsidiary shall be deemed a Restricted Investment at the time
     such Restricted Subsidiary's status terminates in an amount equal to the
     maximum principal amount so guaranteed, for so long as, and to the extent
     that, such guarantee remains outstanding;
 
          (x) the issuance by a Restricted Subsidiary of the Company of
     preferred stock to the Company or to any of its Wholly Owned Restricted
     Subsidiaries; provided, however, that any subsequent event or issuance or
     transfer of any Equity Interests that results in the owner of such
     preferred stock ceasing to be the Company or any of its Wholly Owned
     Restricted Subsidiaries or any subsequent transfer of such preferred stock
     to a Person, other than the Company or one of its Restricted Subsidiaries,
     shall be deemed to be an issuance of preferred stock by such Subsidiary
     that was not permitted by this clause (x); and
 
          (xi) the incurrence by the Company or any of its Restricted
     Subsidiaries of Indebtedness (in addition to Indebtedness permitted by any
     other clause of this paragraph) in an aggregate principal amount (or
     accreted value, as applicable) at any time outstanding not to exceed $10
     million.
 
     For purposes of determining compliance with this covenant, in the event
that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (i) through (xi) above or is
entitled to be incurred pursuant to the first paragraph of this covenant, the
Company shall, in its sole discretion, classify such item of Indebtedness in any
manner that complies with this covenant and such item of Indebtedness shall be
treated as having been incurred pursuant to only one of such clauses or pursuant
to the first paragraph hereof. Accrual of interest, the accretion of accreted
value and the payment of interest in the form of additional Indebtedness will
not be deemed to be an incurrence of Indebtedness for purposes of this covenant.
 
     Liens. The Indenture provides that the Company will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, create,
incur, assume or suffer to exist any Lien on any asset now owned or hereafter
acquired, or any income or profits therefrom or assign or convey any right to
receive income therefrom, except Permitted Liens, to secure (a) any Indebtedness
of the Company or such Restricted Subsidiary, unless prior to, or
contemporaneously therewith, the Notes are equally and ratably secured, or (b)
any Indebtedness of any Guarantor, unless prior to, or contemporaneously
therewith, the Subsidiary
                                       43
<PAGE>   50
 
Guarantees are equally and ratably secured; provided, however, that if such
Indebtedness is expressly subordinated to the Notes or any Subsidiary
Guarantees, the Lien securing such Indebtedness will be subordinated and junior
to the Lien securing the Notes or any Subsidiary Guarantees, as the case may be,
with the same relative priority as such Indebtedness has with respect to the
Notes or any Subsidiary Guarantees.
 
     Dividend and Other Payment Restrictions Affecting Subsidiaries. The
Indenture provides that the Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any encumbrance or restriction on the
ability of any Restricted Subsidiary of the Company or the Company to (i)(x) pay
dividends or make any other distributions to the Company or any of its
Restricted Subsidiaries (1) on its Capital Stock or (2) with respect to any
other interest or participation in, or measured by, its profits, or (y) pay any
Indebtedness owed to the Company or any of its Restricted Subsidiaries, (ii)
make loans or advances to the Company or any of its Restricted Subsidiaries or
(iii) transfer any of its properties or assets to the Company or any of its
Restricted Subsidiaries, except for such encumbrances or restrictions existing
under or by reason of (a) the Indenture, the Notes, Existing Indebtedness and
the Credit Facility as in effect on the Issue Date and any future Liens that may
be permitted to be granted under any other provisions of the Indenture (provided
however, that if the New Credit Facility is established on or prior to the Issue
Date, the foregoing exception shall not apply thereto), (b) applicable law, (c)
any instrument governing Indebtedness or Capital Stock of a Person acquired by
the Company or any of its Restricted Subsidiaries as in effect at the time of
such acquisition (except with respect to Indebtedness incurred in connection
with or in contemplation of such acquisition), which encumbrance or restriction
is not applicable to any Person, or the properties or assets of any Person,
other than the Person, or the property or assets of the Person or such Person's
subsidiaries, so acquired, provided that, in the case of Indebtedness, such
Indebtedness was permitted by the terms of the Indenture to be incurred, (d)
restrictions of the nature described in clause (iii) above by reason of
customary non-assignment provisions in contracts, agreements, and leases entered
into in the ordinary course of business and consistent with past practices, (e)
purchase money obligations for property acquired in the ordinary course of
business that impose restrictions of the nature described in clause (iii) above
on the property so acquired, (f) 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 of the Capital Stock or assets of such
Restricted Subsidiary pending the closing of such sale or disposition, (g)
agreements relating to secured Indebtedness otherwise permitted to be incurred
pursuant to the covenants described under the Indebtedness otherwise permitted
to be incurred pursuant to the covenants described under the captions
"-- Incurrence of Indebtedness and Issuance of Preferred Stock" and "-- Liens"
that limit the right of the debtor to dispose of assets securing such
Indebtedness and (h) Permitted Refinancing Indebtedness in respect of
Indebtedness referred to in clause (a), (c) and (e) of this paragraph, provided
that the restrictions contained in the agreements governing such Permitted
Refinancing Indebtedness are no more restrictive than those contained in the
agreements governing the Indebtedness being refinanced.
 
     Merger, Consolidation, or Sale of Assets. The Indenture provides that the
Company will not consolidate or merge with or into (whether or not the Company
is the surviving corporation), or sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of its properties or assets in one
or more related transactions, to another corporation, Person or entity unless
(i) the Company is the surviving corporation or the entity or the Person formed
by or surviving any such consolidation or merger (if other than the Company) or
to which such sale, assignment, transfer, lease, conveyance or other disposition
shall have been made is a corporation organized or existing under the laws of
the United States, any state thereof or the District of Columbia; (ii) the
entity or Person formed by or surviving any such consolidation or merger (if
other than the Company) or the entity or Person to which such sale, assignment,
transfer, lease, conveyance or other disposition shall have been made assumes
all the obligations of the Company under the Notes and the Indenture pursuant to
a supplemental indenture in a form reasonably satisfactory to the Trustee; (iii)
immediately before and after such transaction no Default or Event of Default
shall have occurred; and (iv) except in the case of a merger of the Company with
or into a Wholly Owned Restricted Subsidiary, the Company or the entity or
Person formed by or surviving any such consolidation or merger (if other than
the Company), or to which such sale, assignment, transfer, lease, conveyance or
other disposition shall have been made (A) will have Consolidated Net Worth
immediately after the transaction equal to or greater than the
                                       44
<PAGE>   51
 
Consolidated Net Worth of the Company immediately preceding the transaction and
(B) will, at the time of such transaction and after giving pro forma effect
thereto as if such transaction had occurred at the beginning of the applicable
four-quarter period, be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the
first paragraph of covenant described above under the caption "-- Incurrence of
Indebtedness and Issuance of Preferred Stock."
 
     Transactions with Affiliates. The Indenture provides that the Company will
not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, make any payment to, or sell, lease, transfer or otherwise dispose
of any properties or assets to, or purchase any property or assets from, or
enter into or make or amend any transaction, contract, agreement, understanding,
loan, advance or guarantee with, or for the benefit of, any Affiliate of any
such Person (each of the foregoing, an "Affiliate Transaction"), unless (i) such
Affiliate Transaction is on terms that are no less favorable to the Company or
the relevant Restricted Subsidiary than those that would have been obtained in a
comparable transaction by the Company or such Restricted Subsidiary with an
unrelated Person and (ii) the Company delivers to the Trustee (a) with respect
to any Affiliate Transaction or series of related Affiliate Transactions
involving aggregate consideration in excess of $1 million, a resolution of its
Board of Directors set forth in an Officers' Certificate certifying that such
Affiliate Transaction complies with clause (i) above, (b) with respect to any
Affiliate Transaction or series of related Affiliate Transaction involving
aggregate consideration in excess of $5 million, a resolution of its Board of
Directors set forth in an Officers' Certificate certifying that such Affiliate
Transaction complies with clause (i) above and that such Affiliate Transaction
has been approved by a majority of the disinterested members of its Board of
Directors, and (c) with respect to any Affiliate Transaction or series of
related Affiliate Transactions involving aggregate consideration in excess of
$10 million, an opinion as to the fairness to the Holders of such Affiliate
Transaction from a financial point of view issued by an Independent Financial
Advisor; provided that none of the following shall be deemed to be Affiliate
Transactions: (1) any employment agreement entered into by the Company or any of
its Restricted Subsidiaries in the ordinary course of business and consistent
with the past practice of the Company or such Restricted Subsidiary, as the case
may be, (2) transactions between or among the Company and/or its Restricted
Subsidiaries, (3) Restricted Payments that are permitted by the covenant
described above under the caption "-- Restricted Payments", (4) fees and

advances to employees for moving, entertainment and travel expenses, drawing
accounts and similar expenditures in the ordinary course of business and
consistent with past practices, (6) maintenance in the ordinary course of
business of customary benefit programs or arrangements for employees, officers

deferred compensation plans and retirement or savings plans and similar plans,
(7) fees and compensation paid to, and indemnity provided on behalf of,
officers, directors or employees of the Company or any of its Restricted
Subsidiaries, as determined by the Board of Directors of the Company or of any
such Restricted Subsidiary, to the extent such fees and compensation are
reasonable and customary as determined by the Board of Directors of the Company
or such Restricted Subsidiary, and (8) transactions between the Company and its
Restricted Subsidiaries, on the one hand, and any Permitted Holders, on the
other, for the purposes of providing investment banking, financial advisory,
banking and other financial services, to the extent such fees and compensation
to such Permitted Holders in such transactions are reasonable and customary as
determined by the Board of Directors of the Company or such Restricted
Subsidiary.
 
     Sale-and-Leaseback Transactions. The Indenture provides that the Company
will not, and will not permit any of its Restricted Subsidiaries to, enter into
any sale-and-leaseback transaction; provided, however, that the Company or any
Restricted Subsidiary, as applicable, may enter into a sale-and-leaseback
transaction if (i) the Company or such Restricted Subsidiary could have (a)
incurred Indebtedness in an amount equal to the Attributable Indebtedness
relating to such sale-and-leaseback transaction pursuant to the covenant
described above under the caption "-- Incurrence of Indebtedness and Issuance of
Preferred Stock" and (b) incurred a Lien to secure such Indebtedness pursuant to
the covenant described under the caption  "-- Liens," (ii) the gross cash
proceeds of such sale-and-leaseback transaction are at least equal to the Fair
Market Value (as determined in accordance with the definition of such term, the
results of which determination shall be set forth in an Officers' Certificate
delivered to the Trustee) of the property that is the
                                       45
<PAGE>   52
 
subject of such sale-and-leaseback transaction and (iii) the transfer of assets
in such sale-and-leaseback transaction is permitted by, and the Company applies
the proceeds of such transaction in compliance with, the covenant described
above under the caption "-- Repurchase at the Option of Holders -- Asset Sales."
 
     Business Activities. The Indenture provides that the Company will not, and
the Company will not permit any of its Restricted Subsidiaries to, directly or
indirectly, engage in any line of business other than a Permitted Business,
except to such extent as would not be material to the Company and its Restricted
Subsidiaries taken as a whole.
 
     Payments for Consent. The Indenture provides that the Company will not, and
will not permit any of its Restricted Subsidiaries to, directly or indirectly,
pay or cause to be paid any consideration, whether by way of interest, fee or
otherwise, to any Holder of any Notes for or as an inducement to any consent,
waiver or amendment of any of the terms or provisions of the Indenture, the
Subsidiary Guarantees or the Notes unless such consideration is offered to be
paid or is paid to all Holders of the Notes that consent, waive or agree to
amend in the time frame set forth in the solicitation documents relating to such
consent, waiver or agreement.
 
     Reports. The Indenture will provide that whether or not the Company is
required by the rules and regulations of the Commission, so long as any Notes
are outstanding, the Company will furnish to each of the Holders of Notes (i)
all quarterly and annual financial information that would be required to be
contained in a filing with the Commission on Forms 10-Q and 10-K if the Company
were required to file such financial information, including a "Management's
Discussion and Analysis of Financial Condition and Results of Operations" that
describes the financial condition and results of operations of the Company and
any consolidated Subsidiaries and, with respect to the annual information only,
reports thereon by the Company's independent public accountants (which shall be
firm(s) of established national reputation and (ii) all information that would
be required to be filed with the Commission on Form 8-K if the Company were
required to file such reports. All such information and reports shall be
delivered to the Holders of Notes on or prior to the dates on which such filings
would have been required to be made had the Company been subject to the rules
and regulations of the Commission. In addition, whether or not required by the
rules and regulations of the Commission, the Company shall file a copy of all
such information and reports with the Commission for public availability within
the time periods specified in the Commission's rules and regulations (unless the
Commission will not accept such a filing) and make such information available to
securities analysts and prospective investors upon request. In addition, the
Company has agreed that, for so long as any Old Notes remain outstanding, they
will furnish to the Holders and to securities analysts and prospective
investors, upon their request, the information required to be delivered pursuant
to Rule 144A(d)(4) under the Securities Act.
 
EVENTS OF DEFAULT AND REMEDIES
 
     The Indenture provides that each of the following constitutes an Event of
Default: (i) default for 30 days in the payment when due of interest on, or, in
the case of the Old Notes only, Liquidated Damages with respect to, the Notes,
(ii) default in payment when due of the principal of or premium, if any, on the
Notes; (iii) failure by the Company or any of its Restricted Subsidiaries to
comply with the provisions described under the captions "-- Certain
Covenants -- Restricted Payments," "-- Certain Covenants -- Incurrence of
Indebtedness and Issuance of Preferred Stock," "-- Certain Covenants -- Merger,
Consolidation, or Sale of Assets," and "-- Repurchase at the Option of Holders";
(iv) failure by the Company or any of its Restricted Subsidiaries for 30 days
after notice to comply with any of its other agreements in the Indenture or the
Notes; (v) default under any mortgage, indenture or instrument under which there
may be issued or by which there may be secured or evidenced any Indebtedness for
money borrowed by the Company or any of its Restricted Subsidiaries (or the
payment of which is guaranteed by the Company or any of its Restricted
Subsidiaries) whether such Indebtedness or guarantee now exists, or is created
after the date of the Indenture, which default (a) is caused by a failure to pay
principal of or premium, if any, or interest on such Indebtedness prior to the
expiration of the grace period provided in such Indebtedness on the date of such
default (a "Payment Default") or (b) results in the acceleration of such
Indebtedness prior to its express maturity and, in each case, the principal
amount of any such Indebtedness, together with the principal amount of any other
such Indebtedness under which there has been a Payment Default or the maturity
of which has been so accelerated, aggregates without duplication $5 million or
more and such default shall not have been cured or acceleration
                                       46

rescinded within five business days after such occurrences; (vi) failure by the
Company or any of its Restricted Subsidiaries to pay final judgments aggregating
in excess of $5 million (excluding amounts covered by insurance), which
judgments are not paid, discharged or stayed for a period of 60 days; (vii)
certain events of bankruptcy or insolvency with respect to the Company or any of
its Restricted Subsidiaries or Significant Subsidiaries; and (viii) except as
permitted by the Indenture, any Subsidiary Guarantee shall be held in any
judicial proceeding to be unenforceable or invalid or shall cease for any reason
to be in full force and effect or any Guarantor, or any Person acting on behalf
of any Guarantor, shall deny or disaffirm its obligations under its Subsidiary
Guarantee (other than by reason of the termination of the Indenture or the
release of any such Subsidiary Guarantee in accordance with the Indenture).
 
     If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately. Notwithstanding the
foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency, with respect to the Company, any Significant
Subsidiary or any group of Subsidiaries that, taken together, would constitute a
Significant Subsidiary, all outstanding Notes will become due and payable
without further action or notice. Holders of the Notes may not enforce the
Indenture or the Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Notes notice of any continuing Default or Event
of Default (except a Default or Event of Default relating to the payment of
principal or interest or, in the case of the Old Notes only, Liquidated Damages)
if it determines that withholding notice is in their interest.
 
     The Holders of a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
Notes waive any existing Default or Event of Default and its consequences under
the Indenture except a continuing Default or Event of Default in the payment of
interest and, in the case of the Old Notes only, Liquidated Damages, if any, on,
or the principal of, the Notes.
 
     The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a
statement specifying such Default or Event of Default.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS
 
     No director, officer, employee, incorporator or stockholder of the Company
or the Guarantors, as such, shall have any liability for any obligations of the
Company under the Notes, the Subsidiary Guarantees or the Indenture or for any
claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder of Notes by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for issuance of
the Notes. Such waiver may not be effective to waive liabilities under the
federal securities laws and it is the view of the Commission that such a waiver
is against public policy.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
     The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Notes ("Legal
Defeasance") except for (i) the rights of Holders of outstanding Notes to
receive payments in respect of the principal of, premium, if any, and interest
and, in the case of the Old Notes only, Liquidated Damages, if any, on such
Notes when such payments are due from the trust referred to below, (ii) the
Company's obligations with respect to the Notes concerning issuing temporary
Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the
maintenance of an office or agency for payment and money for security payments
held in trust, (iii) the rights, powers, trusts, duties and immunities of the
Trustee, and the Company's obligations in connection therewith and (iv) the
Legal Defeasance provisions of the Indenture. In addition, the Company may, at
its option and at any time, elect to have the obligations of the Company
released with respect to certain covenants that are described in the Indenture
("Covenant Defeasance") and thereafter any omission to comply with such
obligations shall not constitute a Default or Event of Default with respect to
the Notes. In the event Covenant Defeasance occurs,
 
                                       47
<PAGE>   54
 
certain events (not including non-payment, bankruptcy, receivership,
rehabilitation and insolvency events) described under "Events of Default" will
no longer constitute an Event of Default with respect to the Notes.
 
     In order to exercise either Legal Defeasance or Covenant Defeasance, (i)
the Company must irrevocably deposit with the Trustee, in trust, for the benefit
of the Holders of the Notes, cash in U.S. dollars, non-callable Government
Securities, or a combination thereof, in such amounts as will be sufficient, in
the opinion of a nationally recognized firm of independent public accountants,
to pay the principal of, premium, if any, and interest and, in the case of the
Old Notes only, Liquidated Damages, if any, on the outstanding Notes on the
stated maturity or on the applicable redemption date, as the case may be, and
the Company must specify whether the Notes are being defeased to maturity or to
a particular redemption date; (ii) in the case of Legal Defeasance, the Company
shall have delivered to the Trustee an opinion of counsel in the United States
reasonably acceptable to the Trustee confirming that (A) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of the Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such opinion of counsel shall confirm that, the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Legal Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Legal Defeasance had not occurred; (iii) in the
case of Covenant Defeasance, the Company shall have delivered to the Trustee an
opinion of counsel in the United States reasonably acceptable to the Trustee
confirming that the Holders of the outstanding Notes will not recognize income,
gain or loss for federal income tax purposes as a result of such Covenant
Defeasance and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Covenant
Defeasance had not occurred; (iv) no Default or Event of Default shall have
occurred and be continuing on the date of such deposit (other than a Default or
Event of Default resulting from the borrowing of funds to be applied to such
deposit) or insofar as Events of Default from bankruptcy or insolvency events
are concerned, at any time in the period ending on the 91st day after the date
of deposit; (v) such Legal Defeasance or Covenant Defeasance will not result in
a breach or violation of, or constitute a default under any material agreement
or instrument (other than the Indenture) to which the Company or any of its
Restricted Subsidiaries is a party or by which the Company or any of its
Restricted Subsidiaries is bound; (vi) the Company must have delivered to the
Trustee an opinion of counsel to the effect that after the 91st day following
the deposit, the trust funds will not be subject to the effect of any applicable
bankruptcy, insolvency, reorganization or similar laws affecting creditors'
rights generally; (vii) the Company must deliver to the Trustee an Officers'
Certificate stating that the deposit was not made by the Company with the intent
of preferring the Holders of Notes over the other creditors of the Company with
the intent of defeating, hindering, delaying or defrauding creditors of the
Company or others; and (viii) the Company must deliver to the Trustee an
Officers' Certificate and an opinion of counsel, each stating that all
conditions precedent provided for relating to the Legal Defeasance or the
Covenant Defeasance have been complied with.
 
SATISFACTION AND DISCHARGE
 
     The Indenture will be discharged and will cease to be of further effect as
to all Notes issued thereunder, when (a) either (i) all such Notes theretofore
authenticated and delivered (except lost, stolen or destroyed Notes which have
been replaced or paid and Notes for whose payment money has heretofore been
deposited in trust and thereafter repaid to the Company) have been delivered to
the Trustee for cancellation; or (ii) all such Notes not theretofore delivered
to such Trustee for cancellation have become due and payable by reason of the
making of a notice of redemption or otherwise or will become due and payable
within one year and the Company has irrevocably deposited or caused to be
deposited with such Trustee as trust funds in trust solely for the benefit of
the Holders, cash in U.S. dollars, non-callable Government Securities, or a
combination thereof, in such amounts as will be sufficient without consideration
of any reinvestment of interest, to pay and discharge the entire indebtedness on
such Notes not theretofore delivered to the Trustee for cancellation for
principal, premium, if any, and accrued interest to the date of maturity or
redemption; (b) no Default or Event of Default with respect to the Indenture or
the Notes shall have occurred and be continuing on the date of such deposit or
shall occur as a result of such deposit and such deposit will not result in a
breach or violation of, or constitute a default under, any other instrument to
which the Company is a party or by which the
                                       48
<PAGE>   55
 
Company is bound; (c) the Company has paid or caused to be paid all sums payable
by it under the Indenture; and (d) the Company has delivered irrevocable
instructions to the Trustee under the Indenture to apply the deposited money
toward the payment of such Notes at maturity or the redemption date, as the case
may be. In addition, the Company must deliver an Officers' Certificate and an
opinion of counsel to the Trustee stating that all conditions precedent to
satisfaction and discharge have been satisfied.
 
TRANSFER AND EXCHANGE
 
     A Holder may transfer or exchange Notes in accordance with the Indenture.
The Registrar and the Trustee may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and the Company may
require a Holder to pay any taxes and fees required by law or permitted by the
Indenture. The Company is not required to transfer or exchange any Note selected
for redemption. Also, the Company is not required to transfer or exchange any
Note for a period of 15 days before a selection of Notes to be redeemed.
 
     The registered Holder of a Note will be treated as the owner of it for all
purposes.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
     Except as provided in the next two succeeding paragraphs, the Indenture,
the Notes or the Subsidiary Guarantees may be amended or supplemented with the
consent of the Holders of at least a majority in principal amount of the Notes
then outstanding (including, without limitation, consents obtained in connection
with a purchase of, or tender offer or exchange offer for, Notes), and any
existing default or compliance with any provision of the Indenture or the Notes
may be waived with the consent of the Holders of a majority in principal amount
of the then outstanding Notes (including consents obtained in connection with a
tender offer or exchange offer for Notes).
 
     Without the consent of each Holder affected, an amendment or waiver may not
(with respect to any Notes held by a non-consenting Holder): (i) reduce the
principal amount of Notes whose Holders must consent to an amendment, supplement
or waiver, (ii) reduce the principal of or change the fixed maturity of any Note
or alter the provisions with respect to the redemption of the Notes (other than
provisions relating to the covenants described above under the caption
"-- Repurchase at the Option of Holders"), (iii) reduce the rate of or change
the time for payment of interest or, in the case of the Old Notes only,
Liquidated Damages on any Note, (iv) waive a Default or Event of Default in the
payment of principal of or premium, if any, or interest or, in the case of the
Old Notes only, Liquidated Damages, if any, on the Notes (except a rescission of
acceleration of the Notes by the Holders of at least a majority in aggregate
principal amount of the Notes and a waiver of the payment default that resulted
from such acceleration), (v) make any Note payable in money other than that
stated in the Notes, (vi) make any change in the provisions of the Indenture
relating to waivers of past Defaults or the rights of Holders of Notes to
receive payments of principal of or premium, if any, or interest or, in the case
of the Old Notes only, Liquidated Damages, if any, on the Notes, (vii) waive a
redemption payment with respect to any Note (other than a payment required by
one of the covenants described above under the caption "-- Repurchase at the
Option of Holders") or (viii) make any change in the foregoing amendment and
waiver provisions.
 
     Notwithstanding the foregoing, without the consent of any Holder of Notes,
the Company and the Trustee may amend or supplement the Indenture, the Notes or
the Subsidiary Guarantees to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Notes in addition to or in place of certificated
Notes, to provide for the assumption of the Company's obligations to Holders of
Notes in the case of a merger or consolidation, to make any change that would
provide any additional rights or benefits to the Holders of Notes or that does
not adversely affect the legal rights under the Indenture of any such Holder, or
to comply with requirements of the Commission in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act or to allow any
Guarantor to guarantee the Notes.

CONCERNING THE TRUSTEE
 
     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim as security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest it must eliminate
such conflict within 90 days, apply to the Commission for permission to continue
or resign.
 
     The Holders of a majority in principal amount of the then 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 in case an Event of Default
shall occur (which shall not be 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.

     Anyone who receives this Prospectus may obtain a copy of the Indenture
without charge by writing to GulfMark Offshore, Inc., 5 Post Oak Park, Suite

President.
 
BOOK-ENTRY, DELIVERY AND FORM
 
     The Old Notes held by Qualified Institutional Buyers are represented by the
Old Global Note and the Exchange Notes will be represented by the Exchange
Global Note. The Old Global Note initially was deposited, and the Exchange
Global Note will be deposited, upon issuance with the Trustee as custodian for
the Depositary, in New York, New York, and registered in the name of the
Depositary or its nominee, in each case for credit to an account of a direct or
indirect participant as described below.
 
     Except as set forth below, the Global Notes may be transferred, in whole
and not in part, only to another nominee of the Depositary or to a successor of
the Depositary or its nominee. Beneficial interests in the Global Notes may not
be exchanged for Notes in certificated form except in the limited circumstances
described below. See "-- Depositary Procedures -- Exchange of Book-Entry Notes
for Certificated Notes."
 
     The Old Global Note (including beneficial interests in the Old Global
Notes) will bear a restrictive legend describing certain restrictions on
transfer to which it is subject. See "The Exchange Offer -- Consequences of
Failure to Exchange." In addition, transfer of beneficial interests in the
Global Notes will be subject to the applicable rules and procedures of the
Depositary and its direct or indirect participants (including, if applicable,
those of the Euroclear System ("Euroclear") and Cedel Bank, S.A. ("CEDEL")),
which may change from time to time.
 
     The Notes may be presented for registration of transfer and exchange at the
offices of the Registrar.
 
DEPOSITARY PROCEDURES
 
     The Depositary has advised the Company that the Depositary is a
limited-purpose trust company created to hold securities for its participating
organizations (collectively, the "Participants") and to facilitate the clearance
and settlement of transactions in those securities between Participants through
electronic book-entry changes in accounts of Participants. The Participants
include securities brokers and dealers (including the Initial Purchasers),
banks, trust companies, clearing corporations and certain other organizations.
Access to the Depositary's system is also available to other entities such as
banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a Participant, either directly or indirectly
(collectively, "Indirect Participants"). Persons who are not Participants may
beneficially own securities held by or on behalf of the Depositary only through
the Participants or Indirect Participants. The ownership interest
 
                                       50
<PAGE>   57
 
and transfer of ownership interest of each actual purchaser of each security
held by or on behalf of the Depositary are recorded on the records of the
Participants and Indirect Participants.
 
     The Depositary has also advised the Company that pursuant to procedures
established by it, (i) upon deposit of the Global Notes, the Depositary will
credit the accounts of Participants with portions of the principal amount of
Global Notes of the individual beneficial interests represented by such Global
Notes and (ii) ownership of such interests in the Global Notes will be shown on,
and the transfer of ownership thereof will be effected only through, records
maintained by the Depositary (with respect to Participants) or by Participants
and the Indirect Participants (with respect to other owners of beneficial
interests in the Global Notes).
 
     Investors in the Global Notes may hold their interests therein directly
through the Depositary, if they are Participants in such system, or indirectly
through organizations (including Euroclear and CEDEL that are Participants in
such system.
 
     The laws of some states require that certain persons take physical delivery
in definitive form of securities that they own. Consequently, the ability to
transfer beneficial interest in a Global Note to such persons may be limited to
that extent. Because the Depositary can act only on behalf of Participants,
which in turn act on behalf of Indirect Participants and certain banks, the
ability of a person having a beneficial interest in the Global Notes to pledge
such interest to persons or entities that do not participate in the Depositary
system, or otherwise take actions in respect of such interests, may be affected
by the lack of physical certificate evidencing such interest. For certain other
restrictions on the transferability of the Notes, see "-- Exchange of Book-Entry
Notes for Certificated Notes."
 
     EXCEPT AS DESCRIBED BELOW, OWNERS OF INTERESTS IN THE GLOBAL NOTES WILL NOT
HAVE NOTES REGISTERED IN THEIR NAMES, WILL NOT RECEIVE PHYSICAL DELIVERY OF
NOTES IN CERTIFICATED FORM AND WILL NOT BE CONSIDERED THE REGISTERED OWNERS, OR
HOLDERS THEREOF UNDER THE INDENTURE FOR ANY PURPOSE.
 
     Payments in respect of the principal and premium and, in the case of Old
Notes only, Liquidated Damages, if any, and interest on a Global Note registered
in the name of the Depositary or its nominee will be payable by the Trustee to
the Depositary or its nominee in its capacity as the registered Holder under the
Indenture. Under the terms of the Indenture, the Company and the Trustee will
treat the persons in whose names the Notes, including the Global Notes, are
registered as the owners thereof for the purpose of receiving such payments and
for any and all other purposes whatsoever. Consequently, neither the Company,
the Trustee nor any agent of the Company or the Trustee has or will have any
responsibility or liability for (i) any aspect of the Depositary's records or
any Participant's or Indirect Participant's records relating to or payments made
on account of beneficial ownership interests in the Global Notes, or for
maintaining, supervising or reviewing any of the Depositary's records or any
Participant's or Indirect Participant's records relating to the beneficial
ownership interests in the Global Notes or (ii) any other matter relating to the
actions and practices of the Depositary or any of its Participants or Indirect
Participants.
 
     The Depositary has advised the Company that its current practices, upon
receipt of any payment in respect of securities such as the Notes (including
principal and interest and, in the case of Old Notes only, Liquidated Damages,
if any), is to credit the accounts of the relevant Participants with the payment
on the payment date, in amounts proportionate to their respective holdings in
principal amount of beneficial interests in the relevant security such as the
Global Notes as shown on the records of the Depositary. Payments by Participants
and the Indirect Participants to the beneficial owners of Notes will be governed
by standing instructions and customary practices and will not be the
responsibility of the Depositary, the Trustee or the Company. Neither the
Company nor the Trustee will be liable for any delay by the Depositary or its
Participants in identifying 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 Depositary or its nominee as the registered owner of the
Notes for all purposes.
 
     Interests in the Global Notes will trade in the Depositary's Same-Day Funds
Settlement System and secondary market trading activity in such interests will,
therefore, settle in immediately available funds, subject in all cases to the
rules and procedures of the Depositary and its Participants. Transfers between
 
                                       51
<PAGE>   58
 
Participants in the Depositary will be effective in accordance with the
Depositary's procedures, and will be settled in same-day funds.
 
     The Depositary has advised the Company that it will take any action
permitted to be taken by a Holder of Notes only at the direction of one or more
Participants to whose account the Depositary interests in the Global Notes are
credited and only in respect of such portion of the aggregate principal amount
of the Notes as to which such Participant or Participants has or have given
direction. However, if there is an Event of Default under the Notes, the
Depositary reserves the right to exchange Global Notes for legend Notes in
certificated form, and to distribute such Notes to its Participants.
 
     The information in this section concerning the Depositary, Euroclear and
CEDEL and their book-entry systems has been obtained from sources that the
Company believes to be reliable, but the Company takes no responsibility for the
accuracy thereof.
 
     Although the Depositary has agreed to the foregoing procedures to
facilitate transfers of interests in the Global Notes among Participants in the
Depositary it is under no obligation to perform or to continue to perform such
procedures, and such procedures may be discontinued at any time. None of the
Company, the Initial Purchasers or the Trustee will have any responsibility for
the performance by the Depositary or its respective Participants or Indirect
Participants of their respective obligations under the rules and procedures
governing their operations.
 
     Exchange of Book-Entry Notes for Certificated Notes. A Global Note is
exchangeable for definitive Notes in registered certificated form if (i) the
Depositary (A) notifies the Company that it is unwilling or unable to continue
as depository for the Global Note and the Company thereupon fails to appoint a
successor depository or (B) has ceased to be a clearing agency registered under
the Exchange Act or (ii) the Company, at its option, notifies the Trustee in
writing that it elects to cause issuance of the Notes in certificated form. In
addition, beneficial interests in a Global Note may be exchanged for
certificated Notes upon request but only upon at least 20 days prior written
notice given to the Trustee by or on behalf of the Depositary in accordance with
customary procedures. In all cases, certificated Notes delivered in exchange for
any Global Note or beneficial interest therein will be registered in names, and
issued in any approved denominations, requested by or on behalf of the
Depositary (in accordance with its customary procedures) and will bear, in the
case of the Old Global Note, a restrictive legend specifying certain
restrictions on transfer referred to in "The Exchange Offer -- Consequences of
Failure to Exchange", unless the Company determines otherwise in compliance with
applicable law.
 
     Certificated Notes. Subject to certain conditions, any person having a
beneficial interest in the Global Note may, upon request to the Trustee,
exchange such beneficial interest for Notes in the form of certificated Notes.
Upon any such issuance, the Trustee is required to register such certificated
Notes in the name of, and cause the same to be delivered to, such person or
persons (or the nominee of any thereof). All such certificated Old Notes would
be subject to legend requirements specifying certain restrictions on transfer
described herein under "The Exchange Offer -- Consequences of Failure to
Exchange." In addition, if (i) the Company notifies the Trustee in writing that
the Depositary is no longer willing or able to act as a depository and the
Company is unable to locate a qualified successor within 90 days or (ii) the
Company, at its option, notifies the Trustee in writing that it elects to cause
the issuance of Notes in the form of certificated Notes under the Indenture,
then, upon surrender by the Global Note Holder of its Global Note, Notes in such
form will be issued to each person that the Global Note Holder and the
Depositary identify as being the beneficial owner of the related Notes.
 
     Neither the Company nor the Trustee will be liable for any delay by the
Global Note Holder or the Depositary in identifying the beneficial owners of
Notes and the Company and the Trustee may conclusively rely on, and will be
protected in relying on, instructions from the Global Note Holder or the
Depositary for all purposes.
 
     Same Day Settlement and Payment. The Indenture will require that payments
in respect of the Notes represented by the Global Note (including principal,
premium, if any, interest and, in the case of the Old Notes only, Liquidated
Damages, if any) be made by wire transfer of immediately available funds to the
 
                                       52
<PAGE>   59
 
accounts specified by the Global Note Holder. With respect to certificated
Notes, the Company will make all payments of principal, premium, if any,
interest and, in the case of the Old Notes only, Liquidated Damages, if any, by
wire transfer of immediately available funds to the accounts specified by the
Holders thereof or, if no such account is specified, by mailing a check to each
such Holder's registered address. The Company expects that secondary trading in
the certificated Notes will also be settled in immediately available funds.
 
REGISTRATION RIGHTS; LIQUIDATED DAMAGES
 
     Pursuant to the Registration Rights Agreement, the Company has agreed to
file with the Commission the Exchange Offer Registration Statement on the
appropriate form under the Securities Act to allow the Holders of Transfer
Restricted Securities who are able to make certain representations the
opportunity to exchange their Transfer Restricted Securities for Exchange Notes
and thereafter, to allow Lehman Brothers Inc. to engage in market-making
transactions with respect to sales of the Exchange Notes. Accordingly, the
Company will prepare and include within the Exchange Offer Registration
Statement a prospectus relating to the Exchange Offer and a prospectus relating
solely to sales of Exchange Notes by Lehman Brothers Inc. in market-making
transactions (including Exchange Notes received in exchange for Old Notes
acquired by Lehman Brothers Inc. in market-making transactions). If (i) the
Company is not required to file the Exchange Offer Registration Statement or
permitted to consummate the Exchange Offer because the Exchange Offer is not
permitted by applicable law or Commission policy or (ii) any Holder of Transfer
Restricted Securities notifies the Company within 20 business days following
consummation of the Exchange Offer that (A) it is prohibited by law or
Commission policy from participating in the Exchange Offer or (B) it may not
resell the Exchange Notes acquired by it in the Exchange Offer to the public
without delivering a prospectus and the prospectus contained in the Exchange
Offer Registration Statement is not appropriate or available for such resales or
(C) that it is a broker-dealer and owns Notes acquired directly from the Company
or an affiliate of the Company, the Company will file with the Commission a
Shelf Registration Statement to cover resales of the Notes by the Holders
thereof who satisfy certain conditions relating to the provision of information
in connection with the Shelf Registration Statement. The Company will use its
best efforts to cause the applicable registration statement to be declared
effective as promptly as possible by the Commission. For purposes of the
foregoing, "Transfer Restricted Securities" means each Old Note until (i) the
date on which such Old Note has been exchanged by a person other than a
broker-dealer for a Exchange Note in the Exchange Offer, (ii) following the
exchange by a broker-dealer in the Exchange Offer of an Old Note for an Exchange
Note, the date on which such Exchange Note is sold to a purchaser who receives
from such broker-dealer on or prior to the date of such sale a copy of the
appropriate prospectus contained in the Exchange Offer Registration Statement,
(iii) the date on which such Old Note has been effectively registered under the
Securities Act and disposed of in accordance with the Shelf Registration
Statement or (iv) the date on which such Old Note is distributed to the public
pursuant to Rule 144 under the Securities Act.
 
     The Registration Rights Agreement provides that (i) the Company will file
an Exchange Offer Registration Statement with the Commission on or prior to 60
days after the Closing Date, (ii) the Company will use its best efforts to have
the Exchange Offer Registration Statement declared effective by the Commission
on or prior to 150 days after the Closing Date, (iii) unless the Exchange Offer
would not be permitted by applicable law or Commission policy, the Company will
commence the Exchange Offer and use its best efforts to issue on or prior to 30
business days after the date on which the Exchange Offer Registration Statement
was declared effective by the Commission, Exchange Notes in exchange for all Old
Notes tendered prior thereto in the Exchange Offer and (iv) if obligated to file
the Shelf Registration Statement, the Company will use its best efforts to file
the Shelf Registration Statement with the Commission on or prior to 60 days
after such filing obligation arises (and in any event within 150 days after the
Closing Date) and to cause the Shelf Registration to be declared effective by
the Commission on or prior to 60 days after the date upon which the Company is
obligated to make such filing. If (a) the Company fails to file any of the
Registration Statements required by the Registration Rights Agreement on or

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     The following sets forth a summary of the material anticipated federal
income tax consequences expected to result to holders from the Exchange Offer
and from the purchase, ownership and disposition of the Exchange Notes. The tax
consequences of these transactions are uncertain. The discussion of the federal
income tax consequences set forth below is based upon the Internal Revenue Code
of 1986, as amended (the "Code"), and judicial decisions and administrative
interpretations thereunder, as of the date hereof, and such authorities may be
repealed, revoked, modified or otherwise interpreted or applied so as to result
in federal income tax consequences different from those discussed below. There
can be no assurance that the Internal Revenue Service (the "IRS") will not
challenge one or more of the tax consequences described herein, and the Company
has not obtained, nor does it intend to obtain, a ruling from the IRS or an
opinion of counsel with respect to the United States federal income tax
consequences of acquiring or holding Exchange Notes. As used herein, United
States Holders means (i) citizens or residents (within the meaning of Section
7701(b) of the Code) of the United States, (ii) corporations, partnerships or
other entities created in or under the laws of the United States or any
political subdivision thereof, (iii) estates, the income of which is subject to
United States federal income taxation regardless of its source, and (iv) in
general, trusts subject to the primary supervision of a court within the United
States and the control of a United States person as described in Section
7701(a)(30) of the Code.
 
     This discussion does not purport to deal with all aspects of United States
federal income taxation that may be relevant to a particular Holder in light of
the Holder's circumstances (for example, persons subject to the alternative
minimum tax provisions of the Code). Also, it is not intended to be wholly
applicable to all categories of investors, some of which (such as dealers in
securities, banks, insurance companies, tax-exempt organizations, and persons
holding Exchange Notes as part of a hedging or conversion transaction or
straddle or persons deemed to sell Exchange Notes under the constructive sale
provisions of the Code) may be subject to special rules. The discussion below is
premised upon the assumption that the Exchange Notes and Old Notes constitute
indebtedness for U.S. federal income tax purposes, and that the Old Notes and
Exchange Notes are held (or would be held if acquired) as capital assets within
the meaning of Section 1221 of the Code. This summary does not discuss the tax
considerations applicable to subsequent purchasers. The discussion also does not
discuss any aspect of state, local or foreign law, nor federal estate and gift
tax law.
 
EXCHANGE OF NOTES
 
     The exchange of Old Notes for Exchange Notes pursuant to the Exchange Offer
should not be a taxable exchange for United States federal income tax purposes.
Accordingly, a holder should have the same adjusted issue price, adjusted basis
and holding period in the Exchange Notes as it had in the Old Notes immediately
before the exchange.
 
STATED INTEREST
 
     The Exchange Notes will be issued without original issue discount. Stated
interest on the Old Notes and Existing Notes will be includable in the holder's
income under such holder's method of accounting.
 
     The Company will annually furnish to certain record holders of Exchange
Notes and to the IRS information with respect to qualified stated interest paid
during the calendar year as may be required under applicable regulations.
 
BOND PREMIUM
 
     Generally, if the Exchange Notes are purchased, or if the Old Notes were
purchased, for an amount in excess of the amount payable at the maturity date
(or a call date, if appropriate) of the Exchange Notes, such excess will
constitute amortizable bond premium that the holder may elect to amortize under
the constant interest method over the period from the date of acquisition to the
date of maturity (or until an earlier call date). If bond premium is amortized,
the amount required to be included in the holder's income each year with respect
to interest on the Note will be reduced by the amount of amortizable bond
premium allocable to such year. An election to amortize bond premium is
available only if the Exchange Notes are held as capital assets. This election
is revocable only with the consent of the IRS and applies to all obligations
owned or
 
                                       66
<PAGE>   73
 
subsequently acquired by the holder. To the extent the excess is deducted as
amortizable bond premium, the holder's adjusted tax basis in the Exchange Notes
will be reduced.
 
MARKET DISCOUNT ON THE EXCHANGE NOTES
 
     To the extent a holder had market discount with respect to an Old Note, the
holder generally will have market discount with respect to an Exchange Note. Any
principal payment or gain realized by a holder on disposition or retirement of
an Exchange Note will be treated as ordinary income to the extent that there is
accrued market discount on the Exchange Note. Unless a holder elects to accrue
under a constant-interest method, accrued market discount is the total market
discount multiplied by a fraction, the numerator of which is the number of days
the holder has held the obligation and the denominator of which is the number of
days from the date the holder acquired the obligation under its maturity. A
holder may be required to defer a portion of its interest deductions for the
taxable year attributable to any indebtedness incurred or continued to purchase
or carry an Exchange Note purchased with market discount. Any such deferred
interest expense would not exceed the market discount that accrues during such
taxable year and is, in general, allowed as a deduction not later than the year
in which such market discount is includable in income. If the holder elects to
include market discount in income currently as it accrues on all market discount
instruments acquired by the holder in that taxable year or thereafter, the
interest deferral rule described above will not apply.
 
SALE, EXCHANGE OR RETIREMENT OF THE EXCHANGE NOTES
 
     Upon the sale, exchange or retirement of an Exchange Note, the holder
generally will recognize gain or loss equal to the difference between the amount
realized on the sale, exchange or retirement (which does not include any amount
attributable to accrued but unpaid interest) and the holder's adjusted tax basis
in the Exchange Note.
 
     A holder's adjusted tax basis in an Exchange Note will generally equal the
holder's adjusted basis for the Old Note exchanged therefor increased by any
market discount previously included in income by such holder with respect to
such Exchange Note and decreased by any payments received thereon that are not
qualified stated interest and the amount of any amortizable bond premium applied
to reduce interest on the Exchange Note.
 
     Gain or loss realized on the sale, exchange or retirement of an Exchange
Note will be capital gain or loss (subject to the market discount rules,
discussed above), and will be long-term if, at the time of sale, exchange or
retirement, the Exchange Note has been held or deemed held for more than one
year. On August 5, 1997, legislation was enacted which, among other things,
reduces to 20% the maximum rate of tax on long-term capital gains on most
capital assets held by an individual for more than 18 months, and under which
gain on most capital assets held by an individual more than one year and up to
18 months is subject to tax at a maximum rate of 28%. Holders are urged to
consult their tax advisor with respects to the effects of legislation. The
deductibility of capital losses is subject to limitations.
 
BACKUP WITHHOLDING
 
     The backup withholding rules require a payor to deduct and withhold a tax
if (a) the payee fails to furnish a taxpayer identification number ("TIN") to
the payor, (b) the IRS notifies the payor that the TIN furnished by the payee is
incorrect, (c) the payee has failed to report properly the receipt of
"reportable payments" and the IRS has notified the payor that withholding is
required, or (d) there has been a failure of the payee to certify under the
penalty of perjury that a payee is not subject to withholding under Section 3405
of the Code. As a result, if any one of the events discussed above occurs with
respect to a holder of Notes, the Company, its paying agent or other withholding
agent will be required to withhold a tax equal to 31% of any "reportable
payment" made in connection with the Notes of such holder. A "reportable
payment" includes, among other things, amounts paid in respect of interest or
original issue discount and amounts paid through brokers in retirement of
securities. Any amounts withheld from a payment to a holder under the backup
withholding rules will be allowed as a refund or credit against such holder's
federal income tax, provided, that the required information is furnished to the
IRS. Certain holders (including, among others, corporations and certain
tax-exempt organizations) are not subject to the backup withholding rules.

     THE FOREGOING DISCUSSION OF CERTAIN FEDERAL INCOME TAX CONSEQUENCES IS FOR
GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. ACCORDINGLY, EACH HOLDER OF THE
OLD NOTES AND EACH PROSPECTIVE HOLDER AND, SUBSEQUENT TO THE EXCHANGE OFFER,
EACH HOLDER, OF EXCHANGE NOTES SHOULD CONSULT SUCH HOLDER'S OWN TAX ADVISOR WITH
RESPECT TO THE TAX CONSEQUENCES TO SUCH HOLDER OF THE ACQUISITION, OWNERSHIP AND
DISPOSITION OF THE EXCHANGE NOTES INCLUDING THE APPLICABILITY AND EFFECT OF
FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX LAWS.

                              PLAN OF DISTRIBUTION
 
     Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer may be a statutory underwriter and must
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange 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
Exchange 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 Company has agreed that it will make this Prospectus, as amended or
supplemented, available to any broker-dealer for use in connection with any such
resale for a period of 180 days after the Registration Statement is declared
effective by the Commission. A broker-dealer that delivers such a prospectus to
purchasers in connection with such resales will be subject to certain of the
civil liability provisions under the Securities Act and will be bound by the
provisions of the Registration Rights Agreement (including certain
indemnification rights and obligations).
 
     The Company will not receive any proceeds from any sale of Exchange Notes
by broker-dealers. Exchange 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 Exchange 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 and/or the purchasers of any such Exchange Notes. Any
broker-dealer that resells Exchange 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 Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of Exchange 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 Registration Statement is declared effective by
the Commission, the Company 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
Company has agreed in the Registration Rights Agreement to indemnify such
broker-dealers against certain liabilities, including liabilities under the
Securities Act.

these vessels typically can be used as supply vessels when they are not
performing anchor handling and towing services.
 
     Bareboat Charter. A charter contract whereby the vessel is chartered
without crew, stores or maintenance support, "the bare hull," for a fixed time
period. The contract results in the charterer being treated as the "disponet
owner" for the full duration of the charter.
 
     Below Deck Capacity. The capacity of the tanks located below the deck of a
vessel which are used to carry various liquid and powdered products utilized in
production and drilling activities such as gas oil, potable water, drilling muds

calculated as the difference between the amount of water displaced by the
unloaded vessel and that displaced by the fully loaded vessel.
 
     Drydocking. The process whereby a vessel is removed from the water to
accomplish repairs and complete classification inspection requirements. With the
exception of crewboats and vessels more than 20 years of age that are generally
drydocked more frequently, drydocks are required twice during the five-year
classification cycle. The time period of a drydocking differs based on type and
age of vessel and extent of survey and repairs needed.

support equipment and, in some locations, standby functions.
 
     Utilization. Total days for which charter hire is earned divided by
calendar days in the periods adjusted for part-year availability caused by
vessel additions or dispositions.
 
     UT 705. A supply vessel design developed by the Norwegian design and
construction firm Ulstein and first constructed in 1974. The vessel was first
designed to haul pipe in support of offshore pipeline construction. Post-1990
versions of this vessel have been enhanced to emphasize improved cargo handling
systems and sophisticated positioning capabilities, both of which provide for
high productivity and versatility in supply roles.
 
     UT 755. A supply vessel design developed by Norwegian design and
construction firm Ulstein. Defined in the North Sea as a medium sized vessel, it
fits the definition of a large supply vessel. Vessels built to this design
incorporate a number of environment drilling units and North Sea platforms. The
vessel has high cargo to size ratio, computer controlled pumping and delivery
systems, flexibility to add additional accommodation or specialty equipment,
circular product tanks for ease of cleaning, large product capacities and
improved maneuvering capability to maximize effective working periods alongside
installations.

PROSPECTUS
 
                            GULFMARK OFFSHORE, INC.
                          8 3/4% SENIOR NOTES DUE 2008
 
                          ---------------------------
 
     The 8 3/4% Senior Notes due 2008 (the "Exchange Notes") of GulfMark
Offshore, Inc. (the "Company") were issued in exchange for the previously
outstanding Senior Notes due 2008 (the "Old Notes" and together with the
Exchange Notes, the "Notes") by the Company.
 
     Interest on the Exchange Notes is payable semi-annually on June 1 and
December 1 of each year, commencing December 1, 1998. The Exchange Notes are
redeemable at the option of the Company, in whole or in part, at any time on or
after June 1, 2003, at the redemption prices set forth herein, plus accrued and
unpaid interest to the date of redemption. At any time prior to June 1, 2001,
the Company may, at its option, redeem up to 35% of the aggregate principal
amount of the Notes outstanding with the net cash proceeds of one or more Public
Equity Offerings (as defined herein) at a redemption price equal to 108.75% of
the principal amount thereof, plus accrued and unpaid interest to the date of
redemption; provided that at least 65% of the aggregate original principal
amount of the Notes remains outstanding immediately after each such redemption.
See "Description of the Notes -- Optional Redemption." In the event of a Change
of Control (as defined herein), each holder of the Notes will have the right to
require the Company to purchase all or any part of such holder's notes at a
purchase price in cash equal to 101% of the aggregate principal amount thereof,
plus accrued and unpaid interest to the date of purchase. See "Description of
the Notes -- Repurchase at the Option of Holders -- Change of Control."
 
     The Exchange Notes are general unsecured obligations of the Company and are
pari passu in right of payment with all existing and future unsecured senior
Indebtedness (as defined herein) of the Company, which may include certain
borrowings under the New Credit Facility (as defined herein) and senior to all
future subordinated indebtedness of the Company. The Company conducts its
operations solely through its Subsidiaries (as defined herein) and, accordingly,
the Exchange Notes are effectively subordinated to (i) all future secured
obligations of the Company to the extent of the assets securing such obligations
and (ii) all existing and future indebtedness and other obligations of the
Company's subsidiaries and trade payables incurred in the ordinary course of
business. Under certain circumstances, the Company's payment obligations under
the Exchange Notes may in the future be jointly and severally guaranteed on a
senior unsecured basis by one or more of the Company's Subsidiaries. See
"Description of the Notes." As of March 31, 1998, on a pro forma basis, after
giving effect to the Offering (as defined herein) and the application of the net
proceeds therefrom, and excluding borrowings that are available under the New
Credit Facility (as defined herein), the Company (exclusive of its
Subsidiaries), would have had no Indebtedness outstanding other than the Notes,
and the Company's Subsidiaries would have had Indebtedness of $0.6 million
outstanding. See "Prospectus Summary -- The Private Placement" and "Description
of Other Indebtedness -- New Credit Facility."

TRADING MARKET FOR THE EXCHANGE NOTES
 
     There is no existing trading market for the Exchange Notes, and there can
be no assurance regarding the future development of a market for the Exchange
Notes or the ability of the Holders of the Exchange Notes to sell their Exchange
Notes or the price at which such Holders may be able to sell their Exchange
Notes. If such market were to develop, the Exchange Notes could trade at prices
that may be higher or lower than their initial offering price depending on many
factors, including prevailing interest rates, the Company's operating results
and the market for similar securities. Although it is not obligated to do so,
Lehman Brothers Inc. intends to make a market in the Exchange Notes. Any such
market-making activity may be discontinued at any time, for any reason, without
notice at the sole discretion of Lehman Brothers Inc. No assurance can be given
as to the liquidity of or the trading market for the Exchange Notes.
 
     Lehman Brothers Inc. may be deemed to be an affiliate of the Company and,
as such, may be required to deliver a prospectus in connection with its
market-making activities in the Exchange Notes. The Company has agreed to
maintain an effective registration statement that would allow Lehman Brothers
Inc. to engage in market-making transactions in the Exchange Notes for a period
of two years from the date of effectiveness of the Registration Statement of
which this Prospectus is a part. Thereafter, the Company may, but is not
required to, maintain the effectiveness of such registration statement to enable
Lehman Brothers Inc. to deliver a prospectus in connection with market-making
transactions in the Exchange Notes. If such registration statement ceases to
remain effective or ceases to contain the current information required therein,
Lehman Brothers Inc. may be precluded from continuing to engage in market-making
transactions in the Exchange Notes, which could adversely affect the market for
the Exchange Notes. The Company has agreed to bear substantially all the costs
and expenses related to such registration statement.

                             SELLING SECURITYHOLDER
 
     This Prospectus has been prepared for and is to be used by Lehman Brothers
Inc. in connection with offers and sales of the Exchange Notes in market-making
transactions (including Exchange Notes received in exchange for Old Notes
acquired by Lehman Brothers Inc. in market-making transactions). As of the date
of this Prospectus, Lehman Brothers Inc. owned $13.6 million aggregate principal
amount of Exchange Notes, which were received in the Exchange Offer in exchange
for an equivalent amount of Old Notes originally acquired in market-making
transactions. Because Lehman Brothers Inc. may sell all or a portion of such
Exchange Notes pursuant to this Prospectus, and because this Prospectus may be
used by Lehman Brothers Inc. in connection with future offers and sales of
Exchange Notes in market-making transactions effected from time to time, no
estimate can be given as to the number and percentage of Exchange Notes that
will be held by Lehman Brothers Inc. upon termination of any such sales.
 
     Affiliates of Lehman Brothers Inc. currently own approximately 25.5% of the
Company's Common Stock. David J. Butters, Chairman of the Board of Directors of
the Company, and Robert B. Millard, a Director of the Company, are Managing
Directors of Lehman Brothers Inc. The address of Lehman Brothers Inc. is 3 World

                              PLAN OF DISTRIBUTION
 
     This Prospectus is to be used by Lehman Brothers Inc. in connection with
offers and sales of the Exchange Notes in market-making transactions effected
from time to time. Lehman Brothers Inc. may act as a principal or agent in such
transactions, including as agent for the counterparty when acting as principal
or as agent for both counterparties, and may receive compensation in the form of
discounts and commissions, including from both counterparties when it acts as
agent for both. Such sales will be made at prevailing market prices at the time
of sale, at prices related thereto or at negotiated prices.
 
     Affiliates of Lehman Brothers Inc. currently own approximately 25.5% of the
Company's Common Stock. David J. Butters, Chairman of the Board of Directors of
the Company, and Robert B. Millard, a Director of the Company, are Managing
Directors of Lehman Brothers Inc. Lehman Brothers Inc. has informed the Company
that it does not intend to confirm sales of the Exchange Notes to any accounts
over which it exercises discretionary authority without the prior specific
written approval of such transactions by the customer.
 
     The Company has been advised by Lehman Brothers Inc. that, subject to
applicable laws and regulations, Lehman Brothers Inc. currently intends to make
a market in the Exchange Notes following completion of the Exchange Offer.
However, Lehman Brothers Inc. is not obligated to do so and any such
market-making may be interrupted or discontinued 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. There can be no assurance that an
active trading market will develop or be sustained. See "Risk Factors -- Trading
Market for the Exchange Notes."
 
     Lehman Brothers Inc. has provided investment banking, financial advisory
and other services to the Company in the past and may provide such services to
the Company in the future. Lehman Brothers Inc. acted as a purchaser in
connection with the initial sale of the Notes and received an underwriting
discount of approximately $1.95 million in connection therewith.
 
     Lehman Brothers Inc. and the Company have entered into an agreement with
respect to the use by Lehman Brothers Inc. of this Prospectus. Pursuant to such
agreement, the Company agreed to bear all registration expenses incurred under
such agreement, and the Company agreed to indemnify Lehman Brothers Inc. against
certain liabilities, including liabilities under the Securities Act.

                                    PART II
 
                   INFORMATION NOT REQUIRED IN THE PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  General
 
     Article Eighth of the Company's Certificate of Incorporation, as amended
("Article Eighth") requires the Company to indemnify its directors, officers and
certain other individuals to the full extent permitted by the Delaware General
Corporation Law ("Delaware GCL") or other applicable laws and allows the Company
to enter into agreements with any person to provide greater or different
indemnification than that provided in Article Eighth or the Delaware GCL.
 
     Article Ninth of the Company's Certificate of Incorporation ("Article
Ninth") limits the personal liability of the Company's directors to the Company
or its shareholders to the full extent permitted by the Delaware GCL, which
currently permits directors to be protected from monetary damages for breach of
their fiduciary duty of care. This limitation has no effect on claims arising
under the federal securities laws.
 
  Indemnification and Insurance
 
     Under the Delaware GCL, directors and officers as well as other employees
and individuals may be indemnified against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement in connection with specified
actions, suits or proceedings, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation such
as a derivative action) if they acted in good faith and in a manner they
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 their conduct was unlawful. A similar standard of
care is applicable in the case of actions by or in the right of the corporation,
except that indemnification extends only to expenses (including attorneys' fees)
incurred in connection with defense or settlement of such an action, and the
Delaware GCL requires court approval before there can be any indemnification
where the person seeking indemnification has been found liable to the
corporation.
 
     Article Eighth provides that each person who is or was or had agreed to
become a director or officer of the Company, and each such person who is or was
serving or who had agreed to serve at the request of the Board of Directors or
an officer of the Company as an employee or agent of the Company, or as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise (including the heirs, executors,
administrators or estate of such person) shall be indemnified by the Company to
the full extent permitted by the Delaware GCL or any other applicable laws as
presently or hereafter in effect. Under Article Eighth, subject to the
limitations on indemnification imposed by the Delaware GCL, a large award
against an officer or director or other appropriate individual could be paid by
the Company, which could materially reduce the assets of the Company.
 
     Article Eighth provides that, without limiting the generality or effect of
the foregoing, the Company may enter into one or more agreements with any person
which provide for indemnification greater or different than that provided in
Article Eighth. Finally, Article Eighth and Article Ninth each provide that any
repeal or modification of such article shall not adversely affect any right or
protection existing thereunder immediately prior to such repeal or modification.
 
     At present there is no pending litigation or proceeding involving a
director or officer of the Company in which indemnification would be required or
permitted by the indemnification agreements. The Board of Directors is not aware
of any threatened litigation or proceeding which may result in a claim for
indemnification under any such indemnification agreement.
 
  Elimination of Liability in Certain Circumstances
 
     Under the Delaware GCL, Article Ninth protects the Company's directors
against monetary damages for breaches of their duty of care, except as set forth
below. The inclusion of Article Ninth in the Company's
 
                                      II-1
<PAGE>   88
 
Certificate of Incorporation means that the Company and its shareholders forego
the ability to bring a cause of action against a director for monetary damages
for certain breaches of fiduciary duty, including actions in connection with
proposals for the acquisition of control of the Company. Directors remain liable
for breaches of their duty of loyalty to the Company and its shareholders, as
well as acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law and transactions from which a director
derives improper personal benefit. Also, Article Ninth does not eliminate
director liability under Section 174 of the Delaware GCL, which makes directors
personally liable for unlawful dividends or unlawful stock repurchases or
redemptions and expressly sets forth a negligence standard with respect to such
liability.
 
     Although Article Ninth provides directors with protection from awards of
monetary damages for breaches of the duty of care, it does not eliminate the
directors' duty of care. Accordingly, Article Ninth has no effect on the
availability of equitable remedies such as an injunction or rescission based
upon a director's breach of the duty of care. The provisions of Article Ninth
which eliminate liability as described above applies to officers of the Company
only if they are directors of the Company and are acting in their capacity as
directors, and does not apply to officers of the Company who are not directors.
 
     The Purchase Agreement dated as of June 2, 1998 between the Company and the
Initial Purchasers contains reciprocal agreements of indemnity between the
Company and the Initial Purchasers as to certain liabilities, including
liabilities under the Securities Act of 1933, as amended (the "Securities Act"),
and in certain circumstances provides for indemnification of the Company's
directors and officers.
 
     The Registration Rights Agreement dated as of June 8, 1998 between the
Company and the Initial Purchasers contains reciprocal agreements of indemnity
between the Company and Holders as to certain liabilities, including liabilities
under the Securities Act, and in certain circumstances provides for
indemnification of the Company's directors and officers.

     (b) Financial Statement Schedules
 
     The following financial statement schedules are included in Part II of the

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 registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
 
     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
     The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

                   DEFINITIONS AND INCORPORATION BY REFERENCE

SECTION 1.01        Definitions.

         "Acquired Debt" means, with respect to any specified Person, (i)
Indebtedness of any other Person existing at the time such other Person is
merged with or into or became a Restricted Subsidiary of such specified Person
or (ii) Indebtedness secured by a Lien encumbering any asset acquired by such
specified Person; provided that, in each case, such Indebtedness was not
incurred in connection with, or in contemplation of, such other Person merging
with or into or becoming a Restricted Subsidiary of such specified Person, or
such encumbered asset being acquired by such Person.

         "Adjusted Net Assets" of a Guarantor at any date means the lesser of
the amount by which (i) the fair value of the property of such Guarantor exceeds
the total amount of liabilities, including, without limitation, contingent
liabilities (after giving effect to all other fixed and contingent liabilities
incurred or assumed on such date), but excluding liabilities under its
Guarantee, of such Guarantor at such date and (ii) the present fair salable
value of the assets of such Guarantor at such date exceeds the amount that will
be required to pay the probable liability of such Guarantor on its debts (after
giving effect to all other fixed and contingent liabilities incurred or assumed
on such date and after giving effect to any collection from any Subsidiary of
such Guarantor in respect of the obligations of such Subsidiary under such
Subsidiary Guarantee), excluding debt in respect of such Subsidiary Guarantee,
as they become absolute and matured.

         "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 purposes of this definition, "control"
(including, with correlative meanings, the terms "controlling," "controlled by"
and "under common control with"), as used with respect to any Person, shall mean
the possession, directly or indirectly, of the power to direct or cause the
direction of the management or policies of such Person, whether through the
ownership of voting securities, by agreement or otherwise; provided that
beneficial ownership of 10% or more of the voting securities of a Person shall
be deemed to be control.

         "Agent" means any Registrar, Paying Agent or co-registrar.

         "Applicable Procedures" means, with respect to any transfer or exchange
of or for beneficial interests in any Global Note, the rules and procedures of
the Depositary, Euroclear and CEDEL that apply to such transfer or exchange.

         "Asset Sale" means (i) the sale, lease, conveyance or other disposition
of any assets or rights (including, without limitation, by way of a sale and
leaseback) other than in the ordinary course of business consistent with past
practices (provided that the sale, lease, conveyance or other disposition of all
or substantially all of the assets of the Company and its Restricted
Subsidiaries taken as a whole will be governed by the covenants described in
Sections 4.15 and 5.01 hereof and not by the provisions of the covenant
described in Section 4.10 hereof), and (ii) the issue or sale by the Company or
any of its Restricted Subsidiaries of Equity Interests of any of the Company's
Restricted Subsidiaries, in the case of either clause (i) or (ii), whether in a
single transaction or a series of related transactions (a) that have a fair
market value in excess of $2,000,000 or (b) for Net Proceeds in excess of
$2,000,000; provided that the following will not be deemed to be Asset Sales:

                                    THE NOTES

SECTION 2.01        Form and Dating.

         The Notes and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A hereto. The Notes may have notations,
legends or endorsements required by law, stock exchange rule or usage. Each Note
shall be dated the date of its authentication. The Notes shall be in
denominations of $1,000 and integral multiples thereof. Subject to Section 4.16,
the Notes may bear notations of Subsidiary Guarantees.

         The terms and provisions contained in the Notes shall constitute, and
are hereby expressly made, a part of this Indenture and the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby. However, to the extent any
provision of any Note conflicts with the express provisions of this Indenture,
the provisions of this Indenture shall govern and be controlling.

         Notes issued in global form shall be substantially in the form of
Exhibit A-1 or A-2 attached hereto (including the Global Note Legend and the
"Schedule of Exchanges in the Global Note"



                                       21
<PAGE>   28

attached thereto). Notes issued in definitive form shall be substantially in the
form of Exhibit A-1 attached hereto (but without the Global Note Legend and
without the "Schedule of Exchanges of Interests in the Global Note" attached
thereto). Each Global Note shall represent such of the outstanding Notes as
shall be specified therein and each shall provide that it shall represent the
aggregate principal amount of outstanding Notes from time to time endorsed
thereon and that the aggregate principal amount of outstanding Notes represented
thereby may from time to time be reduced or increased, as appropriate, to
reflect exchanges and redemptions. Any endorsement of a Global Note to reflect
the amount of any increase or decrease in the aggregate principal amount of
outstanding Notes represented thereby shall be made by the Trustee, the
Depositary or the Note Custodian, at the direction of the Trustee, in accordance
with instructions given by the Holder thereof as required by Section 2.06
hereof.

         Notes offered and sold in reliance on Regulation S shall be issued
initially in the form of the Regulation S Temporary Global Note, which shall be
deposited on behalf of the purchasers of the Notes represented thereby with the
Trustee, at its New York office, as custodian for the Depositary, and registered
in the name of the nominee of the Depository for credit to the accounts of
designated agents holding on behalf of Euroclear or CEDEL, duly executed by the
Company and authenticated by the Trustee as hereinafter provided. The Restricted
Period shall be terminated upon the receipt by the Trustee of (i) a written
certificate from the Depositary, together with copies of certificates from
Euroclear and CEDEL certifying that they have received certification of
non-United States beneficial ownership of 100% of the aggregate principal amount
of the Regulation S Temporary Global Note (except to the extent of any
beneficial owners thereof who acquired an interest therein during the Restricted
Period pursuant to another exemption from registration under the Securities Act
and who will take delivery of a beneficial ownership interest in a 144A Global
Note bearing a Private Placement Legend, all as contemplated by Section 2.06(b)
hereof), and (ii) an Officers' Certificate from the Company. Following the
termination of the Restricted Period, beneficial interests in the Regulation S
Temporary Global Note shall be exchanged for beneficial interests in Regulation
S Permanent Global Notes pursuant to the Applicable Procedures. Simultaneously
with the authentication of Regulation S Permanent Global Notes, the Trustee
shall cancel the Regulation S Temporary Global Note. The aggregate principal
amount of the Regulation S Temporary Global Note and the Regulation S Permanent
Global Notes may from time to time be increased or decreased by adjustments made
on the records of the Trustee and the Depositary or its nominee, as the case may
be, in connection with transfers of interest as hereinafter provided.

         The provisions of the "Operating Procedures of the Euroclear System"
and "Terms and Conditions Governing Use of Euroclear" and the "General Terms and
Conditions of Cedel Bank" and "Customer Handbook" of CEDEL shall be applicable
to transfers of beneficial interests in the Regulation S Temporary Global Note
and the Regulation S Permanent Global Notes that are held by members of, or
Participants, in DTC through Euroclear or CEDEL.

SECTION 2.02        Execution and Authentication.

         Two Officers shall sign the Notes for the Company by manual or
facsimile signature.

         If an Officer whose signature is on a Note no longer holds that office
at the time a Note is authenticated, the Note shall nevertheless be valid.

         A Note shall not be valid until authenticated by the manual signature
of the Trustee. The signature shall be conclusive evidence that the Note has
been authenticated under this Indenture.

         The Trustee shall, upon a written order of the Company signed by two
Officers, authenticate Notes for original issue on the Issue Date up to
$130,000,000 aggregate principal amount of the Notes. The aggregate principal
amount of Notes outstanding at any time may not exceed $200,000,000 except as
provided in Section 2.07 hereof. Additional amounts may be issued after the
Issue Date in one or more series from time to time subject to the limitations
set forth under Section 4.09 hereof.

         The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes. 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 an Agent to deal with Holders or an
Affiliate of the Company.

SECTION 2.03        Registrar and Paying Agent.

         The Company shall maintain an office or agency within the City and
State of New York where Notes may be presented for registration of transfer or
for exchange ("Registrar") and an office or agency where Notes may be presented
for payment ("Paying Agent"). The Registrar shall keep a register of the Notes
and of their transfer and exchange. The Company may appoint one or more
co-registrars and one or more additional paying agents. The term "Registrar"
includes any co-registrar and the term "Paying Agent" includes any additional
paying agent. The Company may change any Paying Agent or Registrar without
notice to any Holder. The Company shall promptly notify the Trustee in writing
of the name and address of any Agent not a party to this Indenture. If the
Company fails to appoint or maintain another entity as Registrar or Paying
Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may
act as Paying Agent or Registrar.

         The Company initially appoints The Depository Trust Company ("DTC") to
act as Depositary with respect to the Global Notes.

         The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Note Custodian with respect to the Global Notes.

SECTION 2.04        Paying Agent to Hold Money in Trust.

         The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal or Liquidated Damages, if any, or interest on the Notes, and will
notify the Trustee of any default by the Company in making any such payment.
While any such default continues, the Trustee may require a Paying Agent to pay
all money held by it to the Trustee. The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee. Upon payment over to
the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall
have no further liability for the money. If the Company or a Subsidiary acts as
Paying Agent, it shall segregate and hold in a separate trust fund for the
benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy
or reorganization proceedings relating to the Company, the Trustee shall serve
as Paying Agent for the Notes.

SECTION 2.05        Holder 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
all Holders and shall otherwise comply with TIA Section 312(a). If the Trustee 
is not the Registrar, the Company shall provide to a Responsible Officer of the
Trustee at least seven 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 Holders of Notes and the Company shall otherwise comply with TIA Section 
312(a).

SECTION 2.06        Transfer and Exchange.

                  (a) Transfer and Exchange of Global Notes. A Global Note may
not be transferred as a whole except by the Depositary to a nominee of the
Depositary, by a nominee of the Depositary to the Depositary or to another
nominee of the Depositary, or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. All Global Notes
will be exchanged by the Company for Definitive Notes if (i) the Company
delivers to the Trustee notice from the Depositary that it is unwilling or
unable to continue to act as Depositary for the Global Notes or that it is no
longer a clearing agency registered under the Exchange Act and, in either case,
a successor Depositary is not appointed by the Company within 90 days after the
date of such notice from the Depositary or (ii) the Company in its sole
discretion notifies the Trustee in writing that it elects to cause issuance of
the Notes in certificated form; provided that in no event shall the Regulation S
Temporary Global Note be exchanged by the Company for Definitive Notes prior to
(x) the expiration of the Restricted Period and (y) the receipt by the Registrar
of any certificates required pursuant to Rule 903 under the Securities Act. Upon
the occurrence of either of the preceding events in (i) or (ii) above,
Definitive Notes shall be issued in such names as the Depositary shall instruct
the Trustee. Global Notes also may be exchanged or replaced, in whole or in
part, as provided in Sections 2.07 and 2.11 hereof. Every Note authenticated and
delivered in exchange for, or in lieu of, a Global Note or any portion thereof,
pursuant to Section 2.07 or 2.11 hereof, shall be authenticated and delivered in
the form of, and shall be, a Global Note. A Global



                                       24
<PAGE>   31

Note may not be exchanged for another Note other than as provided in this
Section 2.06(a), however, beneficial interests in a Global Note may be
transferred and exchanged as provided in Section 2.06(b), (c) or (f) hereof.

                  (b) Transfer and Exchange of Beneficial Interests in the
Global Notes. The transfer and exchange of beneficial interests in the Global
Notes shall be effected through the Depositary, in accordance with the
provisions of this Indenture and the Applicable Procedures. Beneficial interests
in the Restricted Global Notes shall be subject to restrictions on transfer
comparable to those set forth herein to the extent required by the Securities
Act. Transfers of beneficial interests in the Global Notes also shall require
compliance with either subparagraph (i) or (ii) below, as applicable, as well as
one or more of the other following subparagraphs as applicable:

                           (i) Transfer of Beneficial Interests in the Same
                  Global Note. Beneficial interests in any Restricted Global
                  Note may be transferred to Persons who take delivery thereof
                  in the form of a beneficial interest in the same Restricted
                  Global Note in accordance with the transfer restrictions set
                  forth in the Private Placement Legend; provided, however, that
                  prior to the expiration of the Restricted Period transfers of
                  beneficial interests in the Temporary Regulation S Global Note
                  may not be made to a U.S. Person or for the account or benefit
                  of a U.S. Person (other than an Initial Purchaser). Beneficial
                  interests in any Unrestricted Global Note may be transferred
                  only to Persons who take delivery thereof in the form of a
                  beneficial interest in an Unrestricted Global Note. No written
                  orders or instructions shall be required to be delivered to
                  the Registrar to effect the transfers described in this
                  Section 2.06(b)(i).

                           (ii) All Other Transfers and Exchanges of Beneficial
                  Interests in Global Notes. In connection with all transfers
                  and exchanges of beneficial interests (other than a transfer
                  of a beneficial interest in a Global Note to a Person who
                  takes delivery thereof in the form of a beneficial interest in
                  the same Global Note), the transferor of such beneficial
                  interest must deliver to the Registrar (A) (1) a written order
                  from a Participant or an Indirect Participant given to the
                  Depositary in accordance with the Applicable Procedures
                  directing the Depositary to credit or cause to be credited a
                  beneficial interest in another Global Note in an amount equal
                  to the beneficial interest to be transferred or exchanged and
                  (2) instructions given in accordance with the Applicable
                  Procedures containing information regarding the Participant
                  account to be credited with such increase or (B) (1) a written
                  order from a Participant or an Indirect Participant given to
                  the Depositary in accordance with the Applicable Procedures
                  directing the Depositary to cause to be issued a Definitive
                  Note in an amount equal to the beneficial interest to be
                  transferred or exchanged and (2) instructions given by the
                  Depositary to the Registrar containing information regarding
                  the Person in whose name such Definitive Note shall be
                  registered to effect the transfer or exchange referred to in
                  (1) above; provided that in no event shall Definitive Notes be
                  issued upon the transfer or exchange of beneficial interests
                  in the Regulation S Temporary Global Note prior to (x) the
                  expiration of the Restricted Period and (y) the receipt by the
                  Registrar of any certificates required pursuant to Rule 903
                  under the Securities Act. Upon an Exchange Offer



                                       25
<PAGE>   32

                  by the Company in accordance with Section 2.06(f) hereof, the
                  requirements of this Section 2.06(b)(ii) shall be deemed to
                  have been satisfied upon receipt by the Registrar of the
                  instructions contained in the Letter of Transmittal delivered
                  by the Holder of such beneficial interests in the Restricted
                  Global Notes. Upon satisfaction of all of the requirements for
                  transfer or exchange of beneficial interests in Global Notes
                  contained in this Indenture, the Notes and otherwise
                  applicable under the Securities Act, the Trustee shall adjust
                  the principal amount of the relevant Global Note(s) pursuant
                  to Section 2.06(h) hereof.

                           (iii) Transfer of Beneficial Interests to Another
                  Restricted Global Note. A beneficial interest in any
                  Restricted Global Note may be transferred to a Person who
                  takes delivery thereof in the form of a beneficial interest in
                  another Restricted Global Note if the transfer complies with
                  the requirements of clause (ii) above and the Registrar
                  receives the following:

                                    (A) if the transferee will take delivery in
                           the form of a beneficial interest in the 144A Global
                           Note, then the transferor must deliver a certificate
                           in the form of Exhibit B hereto, including the
                           certifications in Item (1) thereof; or

                                    (B) if the transferee will take delivery in
                           the form of the Regulation S Temporary Global Note or
                           the Regulation S Global Note, then the transferor
                           must deliver a certificate in the form of Exhibit B
                           hereto, including the certifications in Item (2)
                           thereof.

                           (iv) Transfer and Exchange of Beneficial Interests in
                  a Restricted Global Note for Beneficial Interests in the
                  Unrestricted Global Note. A beneficial interest in any
                  Restricted Global Note may be exchanged by any holder thereof
                  for a beneficial interest in an Unrestricted Global Note or
                  transferred to a Person who takes delivery thereof in the form
                  of a beneficial interest in an Unrestricted Global Note if the
                  exchange or transfer complies with the requirements of clause
                  (ii) above and:

                                    (A) such exchange or transfer is effected
                           pursuant to the Exchange Offer in accordance with the
                           Registration Rights Agreement and the holder of the
                           beneficial interest to be transferred, in the case of
                           an exchange, or the transferee, in the case of a
                           transfer, is not (1) a broker-dealer, (2) a Person
                           participating in the distribution of the Exchange
                           Notes or (3) a Person who is an affiliate (as defined
                           in Rule 144) of the Company;

                           to the Shelf Registration Statement in accordance
                           with the Registration Rights Agreement;

                           (D) the Registrar receives the following:

                                    (1) if the holder of such beneficial 
                  interest in a Restricted Global Note proposes to exchange such
                  beneficial interest for a beneficial interest in an
                  Unrestricted Global Note, a certificate from such holder in
                  the form of Exhibit C hereto, including the certifications in
                  Item (1)(a) thereof;

                                    (2) if the holder of such beneficial 
                  interest in a Restricted Global Note proposes to transfer such
                  beneficial interest to a Person who shall take delivery
                  thereof in the form of a beneficial interest in an
                  Unrestricted Global Note, a certificate from such holder in
                  the form of Exhibit B hereto, including the certifications in
                  Item (4) thereof; and

                                    (3) in each such case set forth in this 
                  subparagraph (D), an Opinion of Counsel in form reasonably
                  acceptable to the Registrar to the effect that such exchange
                  or transfer is in compliance with the Securities Act and that
                  the restrictions on transfer contained herein and in the
                  Private Placement Legend are not required in order to maintain
                  compliance with the Securities Act.

         If any such transfer is effected pursuant to subparagraph (B) or (D)
above at a time when an Unrestricted Global Note has not yet been issued, the
Company shall issue and, upon receipt of an authentication order in accordance
with Section 2.02 hereof, the Trustee shall authenticate one or more
Unrestricted Global Notes in an aggregate principal amount equal to the
principal amount of beneficial interests transferred pursuant to subparagraph
(B) or (D) above.

         Beneficial interests in an Unrestricted Global Note cannot be exchanged
for, or transferred to Persons who take delivery thereof in the form of, a
beneficial interest in a Restricted Global Note.

         (c) Transfer or Exchange of Beneficial Interests for Definitive Notes.

                  (i) If any holder of a beneficial interest in a Restricted
         Global Note proposes to exchange such beneficial interest for a
         Definitive Note or to transfer such beneficial interest to a Person who
         takes delivery thereof in the form of a Definitive Note, then, upon
         receipt by the Registrar of the following documentation:

the appropriate principal amount.

         (g) Legends. The following legends shall appear on the face of all
Global Notes and Definitive Notes issued under this Indenture unless

                  (i) Private Placement Legend.

                           (A) Except as permitted by subparagraph (B) below,
                  each Global Note and each Definitive Note (and all Notes
                  issued in exchange therefor or substitution thereof) shall
                  bear the legend in substantially the following form:

UNDER THE SECURITIES ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE
TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE
FOREGOING."

                           (B) Notwithstanding the foregoing, any Global Note or
                  Definitive Note issued pursuant to subparagraph (b)(iv),

         (h) Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for
Definitive Notes or a particular Global Note has been redeemed, repurchased or
canceled in whole and not in part, each such Global Note shall be returned to or
retained and canceled by the Trustee in accordance with Section 2.11 hereof. At
any time prior to such cancellation, if any beneficial interest in a Global Note
is exchanged for or transferred to a Person who will take delivery thereof in
the form of a beneficial interest in another Global Note or for Definitive
Notes, the principal amount of Notes represented by such Global Note shall be
reduced accordingly and an endorsement shall be made on such Global Note, by the
Trustee, the Note Custodian or the Depositary at the direction of the Trustee,
to reflect such reduction; and if the beneficial interest is being exchanged for
or transferred to a Person who will take delivery thereof in the form of a
beneficial interest in another Global Note, such other Global Note shall be
increased accordingly and an endorsement shall be made on such Global Note, by
the Trustee, the Note Custodian or by the Depositary at the direction of the
Trustee, to reflect such increase.

         (i) General Provisions Relating to Transfers and Exchanges.

                  (i) To permit registrations of transfers and exchanges, the
         Company shall execute and the Trustee shall authenticate Global Notes
         and Definitive Notes upon the Company's order or at the Registrar's
         request.

                  (ii) No service charge shall be made to a holder of a
         beneficial interest in a Global Note or to a Holder of a Definitive
         Note for any registration of transfer or exchange, but the Company may
         require payment of a sum sufficient to cover any transfer tax or
         similar governmental charge payable in connection therewith (other than
         any such transfer taxes or similar governmental charge payable upon
         exchange or transfer pursuant to Sections 2.10, 3.06, 4.10, 4.15 and
         9.05 hereof).

                  (iii) The Registrar shall not be required to register the
         transfer or exchange of any Note selected for redemption in whole or in
         part, except the unredeemed portion of any Note being redeemed in part.

                  (iv) All Global Notes and Definitive Notes issued upon any
         registration of transfer or exchange of Global Notes or Definitive
         Notes shall be the valid obligations of the Company, evidencing the
         same debt, and entitled to the same benefits under this Indenture, as
         the Global Notes or Definitive Notes surrendered upon such registration
         of transfer or exchange.

                  (v) The Company shall not be required (A) to issue, to
         register the transfer of or to exchange Notes during a period beginning
         at the opening of business 15 days before the day of any selection of
         Notes for redemption under Section 3.02 hereof and ending at the close
         of business on the day of selection, (B) to register the transfer of or
         to exchange any Note so selected for redemption in whole or in part,
         except the unredeemed portion of any



                                       36
<PAGE>   43

         Note being redeemed in part or (C) to register the transfer of or to
         exchange a Note between a record date and the next succeeding Interest
         Payment Date.

                           (vi) Prior to due presentment for the registration of
         a transfer of any Note, the Trustee, any Agent and the Company may deem
         and treat the Person in whose name any Note is registered as the
         absolute owner of such Note for the purpose of receiving payment of
         principal of and interest on such Notes and for all other purposes, and
         none of the Trustee, any Agent or the Company shall be affected by
         notice to the contrary.

                           (vii) The Trustee shall authenticate Global Notes and
         Definitive Notes in accordance with the provisions of Section 2.02
         hereof.

                           (viii) All certifications, certificates and Opinions
         of Counsel required to be submitted to the Registrar pursuant to this
         Section 2.06 to effect a transfer or exchange may be submitted by
         facsimile.

SECTION 2.07        Replacement Notes.

         If any mutilated Note is surrendered to the Trustee or the Company and
the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Note, the Company shall issue and the Trustee, upon the written
order of the Company signed by two Officers of the Company, shall authenticate a
replacement Note if the Trustee's requirements are met. If required by the
Trustee or the Company, an indemnity bond must be supplied by the Holder that is
sufficient in the judgment of the Trustee and the Company to protect the
Company, the Trustee, any Agent and any authenticating agent from any loss that
any of them may suffer if a Note is replaced. The Company may charge for its
expenses in replacing a Note.

         Every replacement Note is an additional obligation of the Company and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder.

SECTION 2.08        Outstanding Notes.

         The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note
does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Note.

         If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

         If the principal amount of any Note is considered paid under Section
4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.



                                       37
<PAGE>   44

         If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Notes payable on that date, then on and after that date such
Notes shall be deemed to be no longer outstanding and shall cease to accrue
interest.

SECTION 2.09        Treasury Notes.

         In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company, shall be considered as
though not outstanding, except that for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent,
only Notes that a Responsible Officer of the Trustee actually knows are so owned
shall be so disregarded.

SECTION 2.10        Temporary Notes.

         Until Definitive Notes are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Notes upon a written order of the
Company signed by two Officers of the Company. Temporary Notes shall be
substantially in the form of Definitive Notes but may have variations that the
Company considers appropriate for temporary Notes and as shall be reasonably
acceptable to the Trustee. Without unreasonable delay, the Company shall prepare
and the Trustee shall authenticate Definitive Notes in exchange for temporary
Notes.

         Holders of temporary Notes shall be entitled to all of the benefits of
this Indenture.

SECTION 2.11        Cancellation.

         The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and 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, replacement or cancellation and shall return such
canceled Notes to the Company. The Company may not issue new Notes to replace
Notes that it has paid or that have been delivered to the Trustee for
cancellation.

SECTION 2.12        Defaulted Interest.

         If the Company defaults in a payment of interest on the Notes, it shall
pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.01 hereof. The Company shall promptly notify the Trustee in
writing of the amount of defaulted interest proposed to be paid on each Note and
the date of the proposed payment. The Company shall fix or cause to be fixed
each such special record date and payment date, provided that no such special
record date shall be less than 10 days prior to the related payment



                                       38
<PAGE>   45

date for such defaulted interest. At least 15 days before the special record
date, the Company (or, upon the written request of the Company, the Trustee in
the name and at the expense of the Company) shall mail or cause to be mailed to
Holders a notice that states the special record date, the related payment date
and the amount of such interest to be paid.

SECTION 2.13        CUSIP Numbers.

         The Company 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 Company will promptly notify the Trustee of any
change in the "CUSIP" numbers.

                            REDEMPTION AND PREPAYMENT

SECTION 3.01        Notices to Trustee.

         If the Company elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 30 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Notes to be redeemed and (iv) the redemption price.

SECTION 3.02        Selection of Notes to be Redeemed.

         If less than all of the Notes are to be redeemed at any time, selection
of Notes for redemption shall be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot
or in accordance with any other method the Trustee considers fair and
appropriate; provided that no Notes of $1,000 or less shall be redeemed in part.
In the event of partial redemption by lot, the particular Notes to be redeemed
shall be selected, unless otherwise provided herein, not less than 30 nor more
than 60 days prior to the redemption date by the Trustee from the outstanding
Notes not previously called for redemption.

         The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of
Notes selected shall be in amounts of $1,000 or whole multiples of $1,000.
Except as provided in the preceding sentence, provisions of this Indenture that
apply to Notes called for redemption also apply to portions of Notes called for
redemption.

SECTION 3.03        Notice of Redemption.

         Subject to the provisions of Section 3.09 hereof, at least 30 days but
not more than 60 days before a redemption date, the Company shall mail or cause
to be mailed, by first class mail, a notice of redemption to each Holder whose
Notes are to be redeemed at its registered address.

         The notice shall identify the Notes (including CUSIP numbers) to be
redeemed and shall state:

                  (a) the redemption date;

                  (b) the redemption price;

                  (c) if any Note is being redeemed in part, the portion of the
principal amount of such Note to be redeemed and that, after the redemption date
upon surrender of such Note, a new Note or Notes in principal amount equal to
the unredeemed portion shall be issued upon cancellation of the original Note;

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

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

                  (f) that, unless the Company defaults in making such
redemption payment, interest on Notes called for redemption ceases to accrue on
and after the redemption date;

                  (g) the paragraph of the Notes and/or Section of this
Indenture pursuant to which the Notes called for redemption are being redeemed;
and

                  (h) 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 Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company shall have delivered to the Trustee, at least 30 days prior to the
redemption date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

SECTION 3.04        Effect of Notice of Redemption.

         Once notice of redemption is mailed in accordance with Section 3.03
hereof, Notes called for redemption become irrevocably due and payable on the
redemption date at the redemption price. A notice of redemption may not be
conditional.

SECTION 3.05        Deposit of Redemption Price.

         No later than 10:00 a.m. New York City Time on the redemption date, the
Company shall deposit with the Trustee or with the Paying Agent money sufficient
to pay the redemption price of and accrued interest and Liquidated Damages, if
any, on all Notes to be redeemed on that date. The Trustee or the Paying Agent
shall promptly return to the Company any money deposited with the Trustee or the
Paying Agent by the Company in excess of the amounts necessary to pay the
redemption price of, and accrued interest and Liquidated Damages, if any, on,
all Notes to be redeemed.

         If the Company complies with the provisions of the preceding paragraph,
on and after the redemption date, interest shall cease to accrue on the Notes or
the portions of Notes called for redemption. If a Note is redeemed on or after
an interest record date but on or prior to the related interest payment date,
then any accrued and unpaid interest and Liquidated Damages, if any, shall be
paid to the Person in whose name such Note was registered at the close of
business on such record date. If any Note called for redemption shall not be so
paid upon surrender for redemption because of the failure of the Company to
comply with the preceding paragraph, interest shall be paid on the unpaid
principal, from the redemption date until such principal is paid, and to the
extent lawful on any interest not paid on such unpaid principal, in each case at
the rate provided in the Notes and in Section 4.01 hereof.

SECTION 3.06        Notes Redeemed in Part.

         Upon surrender of a Note that is redeemed in part, the Company shall
issue and, upon the Company's written request, the Trustee shall authenticate
for the Holder at the expense of the Company a new Note equal in principal
amount to the unredeemed portion of the Note surrendered.

SECTION 3.07        Optional Redemption.

                  (a) Except as set forth in clause (b) of this Section 3.07,
the Notes shall not be redeemable at the Company's option prior to June 1, 2003.
Thereafter, the Notes will be subject to redemption at any time at the option of
the Company in whole or in part, upon not less than 30 nor more than 60 days'
notice, at the redemption prices (expressed as percentages of principal amount)
set forth below plus accrued and unpaid interest and Liquidated Damages, if any,

2001, the Company may on any one or more occasions redeem up to an aggregate of
35% of the principal amount of Notes outstanding at a redemption price of
108.75% of the principal amount thereof, plus accrued and unpaid interest, if
any, and Liquidated Damages, if any, thereon, to the redemption date, with the
net cash proceeds of any Public Equity Offering; provided that at least 65% of
the aggregate principal amount of Notes outstanding on the Issue Date remain
outstanding immediately after each occurrence of such redemption; and provided,
further, that each such redemption shall occur within 60 days of the date of the
closing of such Public Equity Offering.

                  (c) Any redemption pursuant to this Section 3.07 shall be made
pursuant to the provisions of Sections 3.01 through 3.06 hereof.

SECTION 3.08        Mandatory Redemption.

         Except as set forth under Sections 3.09, 4.10 and 4.15 hereof, the
Company shall not be required to make mandatory redemption or sinking fund
payments with respect to the Notes.

SECTION 3.09        Offer to Purchase by Application of Excess Proceeds.

         In the event that, pursuant to Section 4.10 hereof, the Company shall
be required to commence an offer to all Holders to purchase Notes (an "Asset
Sale Offer"), it shall follow the procedures specified below.

         The Asset Sale Offer shall remain open for a period of 20 Business Days
following its commencement and no longer, except to the extent that a longer
period is required by applicable law (the "Offer Period"). No later than five
Business Days after the termination of the Offer Period (the "Purchase Date"),
the Company shall purchase the principal amount of Notes required to be
purchased pursuant to Section 4.10 hereof (the "Offer Amount") or, if less than
the Offer Amount has been tendered, all Notes tendered in response to the Asset
Sale Offer. Payment for any Notes so purchased shall be made in the same manner
as interest payments are made.

         If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest and
Liquidated Damages, if any, shall be paid to the Person in whose name a Note is
registered at the close of business on such record date, and no additional
interest or Liquidated Damages shall be payable to Holders who tender Notes
pursuant to the Asset Sale Offer.

         Upon the commencement of an Asset Sale Offer, the Company shall send,
by first class mail, a notice to the Trustee and each of the Holders, with a
copy to the Trustee. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Asset Sale
Offer. The Asset Sale Offer shall be made to all Holders. The notice, which
shall govern the terms of the Asset Sale Offer, shall state:

Date;

                  (c) that any Note not tendered or accepted for payment shall
continue to accrete or accrue interest;

                  (d) that, unless the Company defaults in making such payment,
any Note accepted for payment pursuant to the Asset Sale Offer shall cease to
accrete or accrue interest after the Purchase Date;

                  (e) that Holders electing to have a Note purchased pursuant to
an Asset Sale Offer may only elect to have all of such Note purchased and may
not elect to have only a portion of such Note purchased;

                  (f) that Holders electing to have a Note purchased pursuant to
any Asset Sale Offer shall be required to surrender the Note, with the form
entitled "Option of Holder to Elect Purchase" on the reverse of the Note
completed, or transfer by book-entry transfer, to the Company, a depositary, if
appointed by the Company, or a Paying Agent at the address specified in the
notice at least three days before the Purchase Date;

                  (g) that Holders shall be entitled to withdraw their election
if the Company, the depositary or the Paying Agent, as the case may be,
receives, not later than the expiration of the Offer Period, a telegram, telex,
facsimile transmission or letter setting forth the name of the Holder, the
principal amount of the Note the Holder delivered for purchase and a statement
that such Holder is withdrawing his election to have such Note purchased;

                  (h) that, if the aggregate principal amount of Notes
surrendered by Holders and holders of any other Indebtedness (including the
Seller Note) entitled to participate in such Asset Sale Offer, if any, exceeds
the Offer Amount, the Company shall select the Notes to be purchased on a pro
rata basis (with such adjustments as may be deemed appropriate by the Company so
that only Notes in denominations of $1,000, or integral multiples thereof, shall
be purchased); and

                  (i) that Holders whose Notes were purchased only in part shall
be issued new Notes equal in principal amount to the unpurchased portion of the
Notes surrendered (or transferred by book-entry transfer).

         On or before the Purchase Date, the Company shall, to the extent
lawful, accept for payment, on a pro rata basis to, the extent necessary, the
Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale
Offer, or if less than the Offer Amount has been tendered, all Notes tendered,
and shall deliver to the Trustee an Officers' Certificate stating that such
Notes or portions thereof were accepted for payment by the Company in accordance
with the terms of this Section 3.09. The Company, the Depositary or the Paying
Agent, as the case may be, shall promptly (but in



                                       43
<PAGE>   50

any case not later than five days after the Purchase Date) mail or deliver to
each tendering Holder an amount equal to the purchase price of the Notes
tendered by such Holder and accepted by the Company for purchase, and the
Company shall promptly issue a new Note, and the Trustee, upon written request
from the Company shall authenticate and make available for delivery such new
Note to such Holder, in a principal amount equal to any unpurchased portion of
the Note surrendered. Any Note not so accepted shall be promptly mailed or
delivered by the Company to the Holder thereof. The Company shall publicly
announce the results of the Asset Sale Offer on the Purchase Date.

         Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

                                   ARTICLE IV

                                    COVENANTS

SECTION 4.01        Payment of Notes.

         The Company shall pay or cause to be paid the principal of, premium, if
any, and interest and Liquidated Damages, if any, on the Notes on the dates and
in the manner provided in the Notes. Principal, interest and Liquidated Damages,
if any, shall be considered paid on the date due if the Paying Agent, if other
than the Company or a Subsidiary thereof, holds as of 10:00 a.m. New York City
Time on the due date money deposited by the Company in immediately available
funds and designated for and sufficient to pay all principal and interest then
due. The Company shall pay all Liquidated Damages, if any, in the same manner on
the dates and in the amounts set forth in the Registration Rights Agreement.

         The Company shall pay interest (including post-petition interest in any
proceeding under the Bankruptcy Code) on overdue principal at the rate borne on
the Notes to the extent lawful; it shall pay interest (including post-petition
interest in any proceeding under the Bankruptcy Code) on overdue installments of
interest and Liquidated Damages (without regard to any applicable grace period)
at the same rate to the extent lawful.

SECTION 4.02        Maintenance of Office or Agency.

         The Company shall maintain in the Borough of Manhattan, the City of New
York, an office or agency (which may be an office of the Trustee or an affiliate
of the Trustee, Registrar or co-registrar) where Notes may be surrendered for
registration of transfer or for exchange and where notices and demands to or
upon the Company in respect of the Notes and this Indenture may be served. The
Company shall 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 Company
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 Corporate Trust Office of the
Trustee.



                                       44
<PAGE>   51

         The Company 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
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York for such purposes. The Company shall 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 Company hereby designates the office of the Trustee at 61 Broadway,
15th Floor, New York, New York, 10006, as one such office or agency of the
Company in accordance with Section 2.03 hereof.

SECTION 4.03        Reports.

                  (a) Whether or not required by the rules and regulations of
the SEC, so long as any Notes are outstanding, the Company shall furnish to each
of the Holders of Notes within the time periods specified in the SEC's rules and
regulations, beginning with annual financial information for the year ended
December 31, 1998, (i) all quarterly and annual financial information that would
be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if
the Company were required to file such financial information, including a
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" that describes the financial condition and results of operations of
the Company and any consolidated Subsidiaries and, with respect to the annual
information only, reports thereon by the Company's independent public
accountants (which shall be firm(s) of established national reputation) and (ii)
all information that would be required to be filed with the SEC on Form 8-K if
the Company were required to file such reports. All such information and reports
shall be delivered to the Holders of Notes on or prior to the dates on which
such filings would have been required to be made had the Company been subject to
the rules and regulations of the SEC. All such information and reports shall be
filed with the SEC on or prior to the dates on which such filings would have
been required to be made had the Company been subject to the rules and
regulations of the SEC. In addition, whether or not required by the rules and
regulations of the SEC, the Company shall file a copy of all such information
and reports with the SEC for public availability within the time periods
specified in the SEC's rules and regulations (unless the SEC will not accept
such a filing) and make such information available to securities analysts and
prospective investors upon request. The Company shall at all times comply with
TIA Section 314(a).

                  (b) For so long as any Notes remain outstanding, the Company
shall furnish to the Holders and to securities analysts and prospective
investors, upon their request, the information required to be delivered pursuant
to Rule 144A(d)(4) under the Securities Act.

                  (c) 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



                                       45
<PAGE>   52

the Company's compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates).

SECTION 4.04        Compliance Certificate.

                  (a) The Company shall deliver to the Trustee, within 90 days
after the end of each fiscal year, an Officers' Certificate stating that a
review of the activities of the Company and its Subsidiaries during the
preceding fiscal year has been made under the supervision of the signing
Officers with a view to determining whether the Company has kept, observed,
performed and fulfilled its obligations under this Indenture, and further
stating, as to each such Officer signing such certificate, that to the best of
his or her knowledge the Company has kept, observed, performed and fulfilled
each and every covenant contained in this Indenture and is not in default in the
performance or observance of any of the terms, provisions and conditions of this
Indenture (or, if a Default or Event of Default shall have occurred, describing
all such Defaults or Events of Default of which he or she may have knowledge and
what action the Company is taking or proposes to take with respect thereto) and
that to the best of his or her knowledge no event has occurred and remains in
existence by reason of which payments on account of the principal of or
interest, if any, on the Notes is prohibited or if such event has occurred, a
description of the event and what action the Company is taking or proposes to
take with respect thereto.

                  (b) So long as not contrary to the then current
recommendations of the American Institute of Certified Public Accountants, the
year-end financial statements delivered pursuant to Section 4.03(a) above shall
be accompanied by a written statement of the Company's independent public
accountants (who shall be a firm of established national reputation) that in
making the examination necessary for certification of such financial statements,
nothing has come to their attention that would lead them to believe that the
Company has violated any provisions of Article 4 or Article 5 hereof or, if any
such violation has occurred, specifying the nature and period of existence
thereof, it being understood that such accountants shall not be liable directly
or indirectly to any Person for any future knowledge of any such violation.

                  (c) The Company shall, so long as any of the Notes are
outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware
of any Default or Event of Default, an Officers' Certificate specifying such
Default or Event of Default and what action the Company is taking or proposes to
take with respect thereto.

SECTION 4.05        Taxes.

         The Company shall pay, and shall cause each of its Subsidiaries to pay,
prior to delinquency, all material taxes, charges, assessments, and governmental
levies except such as are contested in good faith and by appropriate proceedings
or where the failure to effect such payment is not adverse in any material
respect to the Holders of the Notes.



                                       46
<PAGE>   53

SECTION 4.06        Waiver of Stay, Extension and Usury Laws.

         Each of the Company and the Subsidiaries covenants (to the extent that
it may lawfully do so) that it shall not at any time insist upon, plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay,
extension or usury law wherever enacted, now or at any time hereafter in force,
that may affect the covenants or the performance of this Indenture; and each of
the Company and the Subsidiaries (to the extent that it may lawfully do so)
hereby expressly waives all benefit or advantage of any such law, and covenants
that it shall not, by resort to any such law, 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.

SECTION 4.07        Restricted Payments.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or make
any other payment or distribution on account of the Company's or any of its
Restricted Subsidiaries' Equity Interests (including, without limitation, any
payment in connection with any merger or consolidation involving the Company) or
to the direct or indirect holders of the Company's or any of its Restricted
Subsidiaries' Equity Interests in their capacity as such (other than dividends
or distributions payable in Equity Interests (other than Disqualified Stock) of
the Company); (ii) purchase, redeem or otherwise acquire or retire for value
(including without limitation, in connection with any merger or consolidation
involving the Company) any Equity Interests of the Company (other than any such
Equity Interests owned by a Wholly Owned Restricted Subsidiary of the Company);
(iii) make any payment on or with respect to, or purchase, redeem, defease or
otherwise acquire or retire for value any Indebtedness that is subordinated to
the Notes, except a payment of interest or principal at Stated Maturity; or (iv)
make any Restricted Investment (all such payments and other actions set forth in
clauses (i) through (iv) above being collectively referred to as "Restricted
Payments"), unless, at the time of and after giving effect to such Restricted
Payment:

                  (a) no Default or Event of Default shall have occurred and be
continuing or would occur as a consequence thereof;

                  (b) the Company would, at the time of such Restricted Payment
and after giving pro forma effect thereto as if such Restricted Payment had been
made at the beginning of the applicable four-quarter period, have been permitted
to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge
Coverage Ratio test set forth in the first paragraph of Section 4.09 hereof; and

                  (c) such Restricted Payment, together with the aggregate
amount of all other Restricted Payments made by the Company or any of its
Restricted Subsidiaries after the Issue Date (excluding Restricted Payments
permitted by clauses (ii), (iii), (iv), (v), (vi) or (vii) of the next
succeeding paragraph), is less than the sum of (i) 50% of the Consolidated Net
Income of the Company for the period (taken as one accounting period) from the
beginning of the first fiscal quarter immediately following the Issue Date to
the end of the Company's most recently ended fiscal



                                       47
<PAGE>   54

quarter for which internal financial statements are available at the time of
such Restricted Payment (or, if such Consolidated Net Income for such period is
a deficit, less 100% of such deficit), plus (ii) 100% of the aggregate net
proceeds received by the Company (including the fair market value of non-cash
proceeds as determined in good faith by the Board of Directors of the Company
less issuance costs) from the issue or sale, in either case, since the Issue
Date of (A) Equity Interests of the Company (other than Disqualified Stock), or
(B) Disqualified Stock or debt securities of the Company that have been
converted into such Equity Interests (other than Equity Interests (or
Disqualified Stock or convertible or exchangeable debt securities) sold to a
Restricted Subsidiary of the Company and other than Disqualified Stock or debt
securities that have been converted or exchanged into Disqualified Stock), plus
(iii) in case any Unrestricted Subsidiary has been redesignated a Restricted
Subsidiary pursuant to the terms of the Indenture or has been merged,
consolidated or amalgamated with or into, or transfers or conveys assets to or
is liquidated into, the Company or a Restricted Subsidiary and provided that no
Default or Event of Default shall have occurred and be continuing or would occur
as a consequence thereof, the lesser of (A) the book value (determined in
accordance with GAAP) at the date of such redesignation, combination or transfer
of the aggregate Investments made by the Company and its Restricted Subsidiaries
in such Unrestricted Subsidiary (or of the assets transferred or conveyed, as
applicable) and (B) the fair market value of such Investment in such
Unrestricted Subsidiary at the time of such redesignation, combination or
transfer (or of the assets transferred or conveyed, as applicable), in each case
as determined in good faith by the Board of Directors of the Company, whose
determination shall be conclusive and evidenced by a resolution of such Board
and, in each case, after deducting any Indebtedness associated with the
Unrestricted Subsidiary so designated or combined or with the assets so
transferred or conveyed, plus (iv) to the extent not already included in
Consolidated Net Income for such period, without duplication, any Restricted
Investment that was made after the Issue Date is sold for cash or otherwise
liquidated or repaid for cash, the lesser of (A) the cash return of capital with
respect to such Restricted Investment (less the cost of disposition, if any) and
(B) the initial amount of such Restricted Investment, plus (v) $10,000,000.

         The foregoing provisions shall not prohibit (i) the payment of any
dividend within 60 days after the date of declaration thereof, if at said date
of declaration such payment would have complied with the provisions of the
Indenture; (ii) the redemption, repurchase, retirement, defeasance, or other
acquisition of any Indebtedness which is subordinated to the Notes or Equity
Interests of the Company in exchange for, or out of the net cash proceeds of the
substantially concurrent sale (other than to a Restricted Subsidiary of the
Company) of, Equity Interests of the Company (other than any Disqualified
Stock); provided that the amount of any such net cash proceeds that are utilized
for any such redemption, repurchase, retirement, defeasance or other acquisition
shall be excluded from clause (c) (ii) of the preceding paragraph; (iii) the
defeasance, redemption, repurchase or other acquisition of Indebtedness which is
subordinated to the Notes with the net cash proceeds from an incurrence of
Permitted Refinancing Indebtedness; (iv) the payment of any dividend or
distribution by a Restricted Subsidiary of the Company to the holders of its
common Equity Interests on a pro rata basis; (v) the repurchase, redemption or
other acquisition or retirement for value of any Equity Interests of the Company
or any Restricted Subsidiary of the Company held by any employee or director of
the Company (or any of its Subsidiaries), or any former employee or director of
the Company (or any of its Subsidiaries) issued pursuant to any management
equity plan or stock option



                                       48
<PAGE>   55

plan or any other management or employee benefit plan, agreement or trust;
provided, however, that the aggregate price paid for all such repurchased,
redeemed, acquired or retired Equity Interests pursuant to this clause (v) shall
not exceed $1,000,000 in any twelve-month period; (vi) repurchases of Equity
Interests deemed to occur upon the cashless exercise of stock options; and (vii)
reasonable and customary directors' fees to the members of the Company's Board
of Directors, provided that such fees are consistent with past practice,
provided, further, that, with respect to clauses (ii), (iii), (v), (vi) and
(vii) above, no Default or Event of Default shall have occurred and be
continuing immediately after such transaction.

         In determining whether any Restricted Payment is permitted by the
foregoing covenant, the Company may allocate or reallocate all or any portion of
such Restricted Payment among the clauses (i) through (vii) of the preceding
paragraph or among such clauses and the first paragraph of this covenant
including clauses (a), (b) and (c), provided that at the time of such allocation
or reallocation, all such Restricted Payments, or allocated portions thereof,
would be permitted under the various provisions of the foregoing covenant.

         The amount of all Restricted Payments (other than cash) shall be the
Fair Market Value (as determined by the Board of Directors of the Company and as
evidenced by a resolution of the Board of Directors of the Company set forth in
an Officers' Certificate delivered to the Trustee) on the date of the Restricted
Payment of the asset(s) or securities proposed to be transferred or issued by
the Company or such Restricted Subsidiary, as the case may be, pursuant to the
Restricted Payment, such determination to be based upon an opinion or appraisal
by an Independent Financial Advisor if the fair market value of any Restricted
Payment is greater than $10,000,000. Not later than (i) the end of any calendar
quarter in which any Restricted Payment is made or (ii) the making of a
Restricted Payment which, when added to the sum of all previous Restricted
Payments made in a calendar quarter, would cause the aggregate of all Restricted
Payments made in such quarter to exceed $5,000,000, the Company shall deliver to
the Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon which the calculations required by
this covenant were computed, which calculations may be based upon the Company's
latest available financial statements.

         The Board of Directors may designate any Unrestricted Subsidiary to be
a Restricted Subsidiary only if (i) immediately after giving effect to such
designation, the Company is able to incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the
first paragraph of Section 4.09, (ii) immediately before and immediately after
giving effect to such designation, no Default or Event of Default shall have
occurred and be continuing and (iii) the Company certifies that such designation
complies with this covenant. Any such designation by the Board of Directors
shall be evidenced to the Trustee by promptly filing with the Trustee a copy of
the resolution giving effect to such designation and an Officers' Certificate
certifying that such designation complied with the foregoing provisions.

         For purposes of making the determination as to whether such designation
would cause a Default or Event of Default, all outstanding Investments by the
Company and its Restricted Subsidiaries (except to the extent repaid in cash) in
the Subsidiary so designated will be deemed to



                                       49
<PAGE>   56

be Restricted Payments at the time of such designation and will reduce the
amount available for Restricted Payments under the first paragraph of this
covenant. All such outstanding Investments will be deemed to constitute
Investments in an amount equal to the greatest of (i) the net book value
(determined in accordance with GAAP) of such Investments at the time of such
designation, (ii) the fair market value of such Investments at the time of such
designation and (iii) the original fair market value of such Investments at the
time they were made. Such designation will only be permitted if such Restricted
Payment would be permitted at such time and if such Restricted Subsidiary
otherwise meets the definition of an Unrestricted Subsidiary.

         Any such designation by the Board of Directors shall be evidenced to
the Trustee by filing with the Trustee a certified copy of the resolution of the
Board of Directors of the Company giving effect to such designation and an
Officers' Certificate certifying that such designation complied with the
foregoing conditions.

         If, at any time, any Unrestricted Subsidiary would fail to meet the
foregoing requirements as an Unrestricted Subsidiary, it shall thereafter cease
to be an Unrestricted Subsidiary for purposes of the Indenture and any
Indebtedness of such Subsidiary shall be deemed to be incurred as of such date.

SECTION 4.08        Dividend and Other Payment Restrictions Affecting Restricted
                    Subsidiaries.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary of the Company or the Company to (i)(x) pay dividends or
make any other distributions to the Company or any of its Restricted
Subsidiaries (1) on its Capital Stock or (2) with respect to any other interest
or participation in, or measured by, its profits, or (y) pay any Indebtedness
owed to the Company or any of its Restricted Subsidiaries, (ii) make loans or
advances to the Company or any of its Restricted Subsidiaries or (iii) transfer
any of its properties or assets to the Company or any of its Restricted
Subsidiaries, except for such encumbrances or restrictions existing under or by
reason of (a) the Indenture, the Notes, Existing Indebtedness and the Credit
Facility as in effect on the Issue Date and any future Liens that may be
permitted to be granted under any other provisions of the Indenture, (b)
applicable law, (c) any instrument governing Indebtedness or Capital Stock of a
Person acquired by the Company or any of its Restricted Subsidiaries as in
effect at the time of such acquisition (except with respect to Indebtedness
incurred in connection with or in contemplation of such acquisition), which
encumbrance or restriction is not applicable to any Person, or the properties or
assets of any Person, other than the Person, or the property or assets of the
Person or such Person's subsidiaries, so acquired, provided that, in the case of
Indebtedness, such Indebtedness was permitted by the terms of the Indenture to
be incurred, (d) restrictions of the nature described in clause (iii) above by
reason of customary non-assignment provisions in contracts, agreements, and
leases entered into in the ordinary course of business and consistent with past
practices, (e) purchase money obligations for property acquired in the ordinary
course of business that impose restrictions of the nature described in clause
(iii) above on the property so acquired, (f) any restriction with respect to a
Restricted



                                       50
<PAGE>   57

Subsidiary imposed pursuant to an agreement entered into for the sale or
disposition of all or substantially all of the Capital Stock or assets of such
Restricted Subsidiary pending the closing of such sale or disposition, (g)
agreements relating to secured Indebtedness otherwise permitted to be incurred
pursuant to Sections 4.09 and 4.12 hereof that limit the right of the debtor to
dispose of assets securing such Indebtedness and (h) Permitted Refinancing
Indebtedness in respect of Indebtedness referred to in clause (a), (c) and (e)
of this paragraph, provided that the restrictions contained in the agreements
governing such Permitted Refinancing Indebtedness are no more restrictive than
those contained in the agreements governing the Indebtedness being refinanced.

SECTION 4.09        Incurrence of Indebtedness and Issuance of Preferred Stock.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "incur") any Indebtedness (including Acquired
Debt) and that the Company shall not issue any Disqualified Stock and shall not
permit any of its Restricted Subsidiaries to issue any shares of preferred
stock; provided, however, that (a) the Company and any Guarantor may incur
Indebtedness (including Acquired Debt), (b) the Company may issue shares of
Disqualified Stock or (c) a Restricted Subsidiary may incur Acquired Debt, if,
in each case, the Company's Fixed Charge Coverage Ratio for the Company's most
recently ended four full fiscal quarters for which internal financial statements
are available immediately preceding the date on which such additional
Indebtedness is incurred or such Disqualified Stock is issued would have been at
least 2.25 to 1, determined on a pro forma basis (including a pro forma
application of the net proceeds therefrom), as if the additional Indebtedness
had been incurred, or the Disqualified Stock had been issued, as the case may
be, at the beginning of such four-quarter period.

         The provisions of the first paragraph of this covenant shall not apply
to the incurrence of any of the following items of Indebtedness (collectively,
"Permitted Debt"):

                           (i) the incurrence by the Company and the Guarantors
         of Indebtedness represented by the Notes and the Subsidiary Guarantees;

                           (ii) the incurrence by the Company of Indebtedness
         and letters of credit pursuant to any Credit Facility (with letters of
         credit being deemed to have a principal amount equal to the maximum
         potential liability of the Company thereunder) in an aggregate
         principal amount not to exceed $75,000,000, less the sum of (a) the
         amount of Purchase Money Indebtedness incurred by the Company or any of
         its Restricted Subsidiaries under clause (vi) below and outstanding and
         (b) the aggregate amount of all proceeds of Assets Sales that have been
         applied since the Issue Date to permanently reduce the outstanding
         amount of such Indebtedness pursuant to Section 4.10 hereof;

                           (iii) the incurrence by the Company or any of its
         Restricted Subsidiaries of Existing Indebtedness;



                                       51
<PAGE>   58

                           (iv) the incurrence by the Company or any of its
         Restricted Subsidiaries of Permitted Refinancing Indebtedness in
         exchange for, or the net proceeds of which are used to extend,
         refinance, renew, replace, defease or refund, Indebtedness that was
         permitted by the Indenture to be incurred;

                           (v) the incurrence by the Company or any of its
         Restricted Subsidiaries of intercompany Indebtedness between or among
         the Company and any of its Restricted Subsidiaries; provided, however,
         that (i) if the Company or any Guarantor is the obligor on such
         Indebtedness, such Indebtedness is expressly subordinate to the payment
         in full of all Obligations with respect to the Notes and (ii) (A) any
         subsequent issuance or transfer of Equity Interests that results in any
         such Indebtedness being held by a Person other than the Company or a
         Restricted Subsidiary and (B) any sale or other transfer of any such
         Indebtedness to a Person that is not either the Company or a Restricted
         Subsidiary shall be deemed, in each case, to constitute an incurrence
         of such Indebtedness by the Company or such Restricted Subsidiary, as
         the case may be;

                           (vi) the incurrence by the Company or any of its
         Restricted Subsidiaries of Purchase Money Indebtedness, in an aggregate
         principal amount (or amount of Capital Lease Obligations), including
         all Permitted Refinancing Indebtedness incurred to refund, refinance or
         replace Purchase Money Indebtedness incurred pursuant to this clause
         (vi), not to exceed $45,000,000 at any time outstanding;

                           (vii) the incurrence by the Company or any of its
         Restricted Subsidiaries of obligations in the ordinary course of
         business under (A) trade letters of credit which are to be repaid in
         full not more than one year after the date on which such Indebtedness
         is originally incurred to finance the purchase of goods by the Company
         or a Restricted Subsidiary of the Company; (B) standby letters of
         credit issued for the purpose of supporting (1) workers' compensation
         liabilities of the Company or any of its Restricted Subsidiaries, or
         (2) performance, payment, deposit or surety obligations of the Company
         or any of its Restricted Subsidiaries; and (C) bid, advance payment and
         performance bonds and surety bonds of the Company and its Restricted
         Subsidiaries, and refinancings thereof;

                           (viii) the incurrence by the Company or any of its
         Restricted Subsidiaries of (x) Financial Hedging Obligations that are
         incurred for the purpose of fixing or hedging interest rate risk
         (including with respect to any floating rate Indebtedness that is
         permitted by the terms of the Indenture to be outstanding), but only to
         the extent such obligations do not exceed 105% of the aggregate
         principal amount of the Indebtedness to which such obligations relate,
         and (y) Currency Hedging Obligations in connection with the conduct of
         the Permitted Business in currencies other than the United States
         Dollar, and, in the case of clauses (x) and (y) not for speculative
         purposes and incurred in the ordinary course of business consistent
         with prudent business practices;

                           (ix) the guarantee by the Company or any Restricted
         Subsidiary of the Company or a Restricted Subsidiary of the Company
         that was permitted to be incurred by



                                       52
<PAGE>   59

         another provision of this covenant; provided, that the guarantee of any
         Indebtedness under this clause (ix) by a Restricted Subsidiary of the
         Company that ceases to be a Restricted Subsidiary shall be deemed a
         Restricted Investment at the time such Restricted Subsidiary's status
         terminates in an amount equal to the maximum principal amount so
         guaranteed, for so long as, and to the extent that, such guarantee
         remains outstanding;

                           (x) the issuance by a Restricted Subsidiary of the
         Company of preferred stock to the Company or to any of its Wholly Owned
         Restricted Subsidiaries; provided, however, that any subsequent event
         or issuance or transfer of any Equity Interests that results in the
         owner of such preferred stock ceasing to be the Company or any of its
         Wholly Owned Restricted Subsidiaries or any subsequent transfer of such
         preferred stock to a Person, other than the Company or one of its
         Restricted Subsidiaries, shall be deemed to be an issuance of preferred
         stock by such Subsidiary that was not permitted by this clause (x); or

                           (xi) the incurrence by the Company or any of its
         Restricted Subsidiaries of Indebtedness (in addition to Indebtedness
         permitted by any other clause of this paragraph) in an aggregate
         principal amount (or accreted value, as applicable) at any time
         outstanding not to exceed $10,000,000.

         For purposes of determining compliance with this covenant, in the event
that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (i) through (xi) above or is
entitled to be incurred pursuant to the first paragraph of this covenant, the
Company shall, in its sole discretion, classify such item of Indebtedness in any
manner that complies with this covenant and such item of Indebtedness shall be
treated as having been incurred pursuant to only one of such clauses or pursuant
to the first paragraph hereof. Accrual of interest, the accretion of accreted
value and the payment of interest in the form of additional Indebtedness will
not be deemed to be an incurrence of Indebtedness for purposes of this covenant.

SECTION 4.10        Asset Sales.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, engage in an Asset Sale unless (i) the Company or such
Restricted Subsidiary, as the case may be, receives consideration at the time of
such Asset Sale at least equal to the fair market value (which shall be
determined in good faith by the Company's Board of Directors) of the assets or
Equity Interests issued or sold or otherwise disposed of and (ii) at least 75%
of the consideration therefor received by the Company or such Restricted
Subsidiary is in the form of cash or Cash Equivalents; provided that the amount
of (x) any liabilities (as shown on the Company's or such Restricted
Subsidiary's most recent balance sheet), of the Company or any Restricted
Subsidiary of the Company (other than contingent liabilities and liabilities
that are by their terms subordinated to the Notes or any Subsidiary Guarantee)
that are assumed by the transferee of any such assets pursuant to a customary
novation agreement that releases the Company or such Restricted Subsidiary from
further liability and (y) any securities, notes or other obligations received by
the Company or any such Restricted Subsidiary from such transferee that are
immediately converted by the Company or such Restricted Subsidiary into cash (to
the extent of the cash received), shall be deemed to be cash for purposes of



                                       53
<PAGE>   60

this provision and provided, further, that any Asset Sale pursuant to a
condemnation, appropriation or other similar taking, including by deed in lieu
of condemnation, or pursuant to the foreclosure or other enforcement of a
Permitted Lien or exercise by the related lienholder of rights with respect
thereto, including by deed or assignment in lieu of foreclosure shall not be
required to satisfy the conditions set forth in clauses (i) and (ii) of this
paragraph.

         Within 270 days after the receipt of any Net Proceeds from an Asset
Sale, the Company or such Restricted Subsidiary, as the case may be, may apply
such Net Proceeds, at its option, (a) to permanently repay Indebtedness for
borrowed money other than Subordinated Indebtedness (and to correspondingly
permanently reduce the commitments with respect thereto in the case of revolving
borrowings), (b) to acquire a controlling interest in another business or all or
substantially all of the assets of a business, engaged in a Permitted Business,
or (c) to acquire other non-current assets to be used in a Permitted Business,
provided that the Company or such Restricted Subsidiary will have complied with
clause (b) or (c) if, within 270 days of such Asset Sale, the Company or such
Restricted Subsidiary shall have commenced and not completed or abandoned an
investment in compliance with clause (b) or (c) and such Investment is
substantially completed within 90 days after the first anniversary of such Asset
Sale. Pending the final application of any such Net Proceeds, the Company may
temporarily reduce Indebtedness under any Credit Facility or otherwise invest
such Net Proceeds in any manner that is not prohibited by the Indenture. Any Net
Proceeds from Asset Sales that are not applied or invested as provided in the
first sentence of this paragraph shall be deemed to constitute "Excess
Proceeds." When the aggregate amount of Excess Proceeds exceeds $10,000,000, the
Company shall be required to make an offer to all Holders of Notes and other
Indebtedness that ranks by its terms pari passu in right of payment with the
Notes and the terms of which contain substantially similar requirements with
respect to the application of net proceeds from asset sales as are contained in
the Indenture (an "Asset Sale Offer") to purchase on a pro rata basis the
maximum principal amount of Notes, that is an integral multiple of $1,000, that
may be purchased out of the Excess Proceeds, at an offer price in cash in an
amount equal to 100% of the principal amount thereof plus accrued and unpaid
interest and Liquidated Damages thereon, if any, to the date of purchase, in
accordance with the procedures set forth in Section 3.09 hereof. To the extent
that the aggregate amount of Notes and other such Indebtedness tendered pursuant
to an Asset Sale Offer is less than the Excess Proceeds, the Company may use any
remaining Excess Proceeds for general corporate purposes. If the aggregate
principal amount of Notes surrendered by Holders thereof exceeds the amount of
Excess Proceeds, the Trustee shall select the Notes to be purchased on a pro
rata basis. Upon completion of such offer to purchase, the amount of Excess
Proceeds shall be reset at zero.

SECTION 4.11        Transactions with Affiliates.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, make any payment to, or sell, lease,
transfer or otherwise dispose of any properties or assets to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate of any such Person (each of the foregoing, an
"Affiliate Transaction"), unless (i) such Affiliate Transaction is on terms that
are no less favorable to the Company or the relevant Restricted



                                       54
<PAGE>   61

Subsidiary than those that would have been obtained in a comparable transaction
by the Company or such Restricted Subsidiary with an unrelated Person and (ii)
the Company delivers to the Trustee (a) with respect to any Affiliate
Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $1,000,000, a resolution of its Board of Directors
set forth in an Officers' Certificate certifying that such Affiliate Transaction
complies with clause (i) above, (b) with respect to any Affiliate Transaction or
series of related Affiliate Transaction involving aggregate consideration in
excess of $5,000,000, a resolution of its Board of Directors set forth in an
Officers' Certificate certifying that such Affiliate Transaction complies with
clause (i) above and that such Affiliate Transaction has been approved by a
majority of the disinterested members of its Board of Directors, and (c) with
respect to any Affiliate Transaction or series of related Affiliate Transactions
involving aggregate consideration in excess of $10,000,000, an opinion as to the
fairness to the Holders of such Affiliate Transaction from a financial point of
view issued by an Independent Financial Advisor; provided that none of the
following shall be deemed to be Affiliate Transactions: (1) any employment
agreement entered into by the Company or any of its Restricted Subsidiaries in
the ordinary course of business and consistent with the past practice of the
Company or such Restricted Subsidiary, as the case may be, (2) transactions
between or among the Company and/or its Restricted Subsidiaries, (3) Restricted
Payments that are permitted by Section 4.07 hereof, (4) fees and compensation
paid to, and indemnity provided on behalf of, officers, directors, employees or
consultants of the Company and of its Restricted Subsidiaries in their capacity
as such, to the extent such fees and compensation are reasonable and customary,
(5) advances to employees for moving, entertainment and travel expenses, drawing
accounts and similar expenditures in the ordinary course of business and
consistent with past practices, (6) maintenance in the ordinary course of
business of customary benefit programs or arrangements for employees, officers
or directors, including vacation plans, health and life insurance plans,
deferred compensation plans and retirement or savings plans and similar plans,
(7) fees and compensation paid to, and indemnity provided on behalf of,
officers, directors or employees of the Company or any of its Restricted
Subsidiaries, as determined by the Board of Directors of the Company or of any
such Restricted Subsidiary, to the extent such fees and compensation are
reasonable and customary as determined by the Board of Directors of the Company
or such Restricted Subsidiary, and (8) transactions between the Company and its
Restricted Subsidiaries, on the one hand, and any Permitted Holders, on the
other, for the purposes of providing investment banking, financial advisory,
banking and other financial services, to the extent such fees and compensation
to such Permitted Holders in such transactions are reasonable and customary as
determined by the Board of Directors of the Company or such Restricted
Subsidiary.

SECTION 4.12        Liens.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist any Lien on any asset now owned or hereafter acquired, or any income or
profits therefrom or assign or convey any right to receive income therefrom,
except Permitted Liens, to secure (a) any Indebtedness of the Company or such
Restricted Subsidiary, unless prior to, or contemporaneously therewith, the
Notes are equally and ratably secured, or (b) any Indebtedness of any Guarantor,
unless prior to, or contemporaneously therewith, the Subsidiary Guarantees are
equally and ratably secured; provided, however, that if such



                                       55
<PAGE>   62

Indebtedness is expressly subordinated to the Notes or any Subsidiary
Guarantees, the Lien securing such Indebtedness will be subordinated and junior
to the Lien securing the Notes or any Subsidiary Guarantees, as the case may be,
with the same relative priority as such Indebtedness has with respect to the
Notes or any Subsidiary Guarantees.

SECTION 4.13        Business Activities.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, engage in any line of business other
than a Permitted Business, except to such extent as would not be material to the
Company and its Restricted Subsidiaries taken as a whole.

SECTION 4.14        Corporate Existence.

         Subject to Articles 5 and 10 hereof, the Company shall do or cause to
be done all things necessary to preserve and keep in full force and effect (i)
its corporate existence, and the corporate, partnership or other existence of
each of its Restricted Subsidiaries, in accordance with the respective
organizational documents (as the same may be amended from time to time) of the
Company or any such Restricted Subsidiary and (ii) the rights (charter and
statutory), licenses and franchises of the Company and its Restricted
Subsidiaries; provided, however, that the Company shall not be required to
preserve any such right, license or franchise, or the corporate, partnership or
other existence of any of its Restricted Subsidiaries, if the Board of Directors
shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company and its Restricted Subsidiaries, taken as
a whole, and that the loss thereof is not adverse in any material respect to the
Holders of the Notes.

SECTION 4.15        Offer to Repurchase upon Change of Control.

                  (a) Upon the occurrence of a Change of Control, each Holder of
Notes will have the right to require the Company to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of such Holder's Notes
pursuant to the offer described below (the "Change of Control Offer") at an
offer price in cash equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest and Liquidated Damages, if any, thereon, to the date
of purchase (the "Change of Control Payment").

         Within 30 days following any Change of Control, the Company will mail a
notice to each Holder stating: (i) the description of the transaction or
transactions that constitute the Change of Control and that the Change of
Control Offer is being made pursuant to this Section 4.15 and that all Notes
tendered will be accepted for payment; (ii) the purchase price and the purchase
date, which shall be no earlier than 30 days and no later than 60 days from the
date such notice is mailed (the "Change of Control Payment Date"); (iii) that
any Note not tendered will continue to accrue interest and Liquidated Damages,
if any; (iv) that, unless the Company defaults in the payment of the Change of
Control Payment, all Notes accepted for payment pursuant to the Change of
Control Offer shall cease to accrue interest after the Change of Control Payment
Date; (v) that Holders electing to have any Notes purchased pursuant to a Change
of Control Offer will be required to surrender the



                                       56
<PAGE>   63

Notes, with the form entitled "Option of Holder to Elect Purchase" on the
reverse of the Notes completed, to the Paying Agent at the address specified in
the notice prior to the close of business on the third Business Day preceding
the Change of Control Payment Date; (vi) that Holders will be entitled to
withdraw their election if the Paying Agent receives, not later than the close
of business on the second Business Day preceding the Change of Control Payment
Date, a telegram, telex, facsimile transmission or letter setting forth the name
of the Holder, the principal amount of Notes delivered for purchase, and a
statement that such Holder is withdrawing his election to have the Notes
purchased; and (vii) that Holders whose Notes are being purchased only in part
will be issued new Notes equal in principal amount to the unpurchased portion of
the Notes surrendered, which unpurchased portion must be equal to $1,000 in
principal amount or an integral multiple thereof. The Company shall comply with
the requirements of Rule 14e-1 under the Exchange Act and any other securities
laws and regulations thereunder to the extent such laws and regulations are
applicable in connection with the repurchase of Notes as a result of a Change of
Control.

                  (b) On the Change of Control Payment Date, the Company will,
to the extent lawful, (i) accept for payment all Notes or portions thereof
properly tendered pursuant to the Change of Control Offer, (ii) deposit with the
Paying Agent an amount equal to the Change of Control Payment in respect of all
Notes or portions thereof so tendered and (iii) deliver or cause to be delivered
to the Trustee the Notes so accepted together with an Officers' Certificate
stating the aggregate principal amount of Notes or portions thereof being
purchased by the Company. The Paying Agent will promptly mail to each Holder of
Notes so tendered the Change of Control Payment for such Notes, and the Trustee
will promptly authenticate and mail (or cause to be transferred by book entry)
to each Holder a new Note equal in principal amount to any unpurchased portion
of the Notes surrendered, if any; provided that each such new Note will be in a
principal amount of $1,000 or an integral multiple thereof. Prior to complying
with the provisions of this Section 4.15, but in any event within 90 days
following a Change of Control, the Company will either repay all outstanding
Indebtedness or obtain the requisite consents, if any, under all agreements
governing outstanding Indebtedness to permit the repurchase of Notes required by
this covenant. The Company will publicly announce the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Payment
Date.

                  (c) The Company will not be required to make a Change of
Control Offer upon a Change of Control if a third party makes the Change of
Control Offer in the manner, at the times and otherwise in compliance with the
requirements set forth herein applicable to a Change of Control Offer made by
the Company and purchases all Notes validly tendered and not withdrawn under
such Change of Control Offer.

SECTION 4.16        Subsidiary Guarantees of Certain Indebtedness.

         No Subsidiary of the Company may guarantee any Indebtedness of the
Company, unless such Subsidiary (i) executes and delivers to the Trustee a
supplemental indenture in form and substance satisfactory to the Trustee
providing that such Subsidiary shall become a Guarantor under the Indenture and
evidencing such Subsidiary Guarantee of the Notes in accordance with Article 10
hereof, such Subsidiary Guarantee to be a general unsecured obligation of the
Guarantor ranking



                                       57
<PAGE>   64

pari passu in right of payment with all other current or future senior
Indebtedness of such Guarantor, and senior in right of payment to any
Subordinated Indebtedness of such Guarantor and (ii) delivers an opinion of
counsel to the effect, inter alia, that such supplemental indenture has been
duly authorized and executed by such Subsidiary. Neither the Company nor any
Guarantor shall be required to make a notation on the Notes to reflect any such
subsequent Subsidiary Guarantee. Nothing in this Section 4.16 shall be construed
to permit any Restricted Subsidiary of the Company to incur Indebtedness
otherwise prohibited by Section 4.09 hereof.

SECTION 4.17        Payments for Consent.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fee or otherwise, to any Holder of
any Notes for or as an inducement to any consent, waiver or amendment of any of
the terms or provisions of this Indenture, the Subsidiary Guarantees or the
Notes unless such consideration is offered to be paid or is paid to all Holders
of the Notes that consent, waive or agree to amend in the time frame set forth
in the solicitation documents relating to such consent, waiver or agreement.

SECTION 4.18        Sale-and-Leaseback Transactions.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, enter into any sale-and-leaseback transaction; provided,
however, that the Company or any Restricted Subsidiary, as applicable, may enter
into a sale-and-leaseback transaction if (i) the Company or such Restricted
Subsidiary could have (a) incurred Indebtedness in an amount equal to the
Attributable Indebtedness relating to such sale-and-leaseback transaction
pursuant to Section 4.09 hereof and (b) incurred a Lien to secure such
Indebtedness pursuant to Section 4.12 hereof, (ii) the gross cash proceeds of
such sale-and-leaseback transaction are at least equal to the Fair Market Value
(as determined in accordance with the definition of such term, the results of
which determination shall be set forth in an Officers' Certificate delivered to
the Trustee) of the property that is the subject of such sale-and-leaseback
transaction and (iii) the transfer of assets in such sale-and-leaseback
transaction is permitted by, and the Company applies the proceeds of such
transaction in compliance with Section 4.10 hereof.

convey or otherwise dispose of all or substantially all of its properties or
assets in one or more related transactions, to another corporation, Person or
entity unless (i) the Company is the surviving corporation or the entity or the

the Company) or to which



                                       58
<PAGE>   65

such sale, assignment, transfer, lease, conveyance or other disposition shall
have been made is a corporation organized or existing under the laws of the
United States, any state thereof or the District of Columbia; (ii) the entity or
Person formed by or surviving any such consolidation or merger (if other than
the Company) or the entity or Person to which such sale, assignment, transfer,
lease, conveyance or other disposition shall have been made assumes all the
obligations of the Company under the Notes and the Indenture pursuant to a
supplemental indenture in a form reasonably satisfactory to the Trustee; (iii)
immediately before and after such transaction no Default or Event of Default
shall have occurred; and (iv) except in the case of a merger of the Company with
or into a Wholly Owned Restricted Subsidiary, the Company or the entity or
Person formed by or surviving any such consolidation or merger (if other than
the Company), or to which such sale, assignment, transfer, lease, conveyance or
other disposition shall have been made (A) will have Consolidated Net Worth
immediately after the transaction equal to or greater than the Consolidated Net
Worth of the Company immediately preceding the transaction and (B) will, at the
time of such transaction and after giving pro forma effect thereto as if such
transaction had occurred at the beginning of the applicable four-quarter period,
be permitted to incur at least $1.00 of additional Indebtedness pursuant to the
Fixed Charge Coverage Ratio test set forth in the first paragraph of Section
4.09.

SECTION 5.02        Successor Corporation Substituted.

         Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the assets
of the Company in accordance with Section 5.01 hereof, the successor corporation
formed by such consolidation or into or with which the Company is merged or to
which such sale, assignment, transfer, lease, conveyance or other disposition is
made shall succeed to, and be substituted for (so that from and after the date
of such consolidation, merger, sale, lease, conveyance or other disposition, the
provisions of this Indenture referring to the "Company" shall refer instead to
the successor corporation and not to the Company), and may exercise every right
and power of the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein.

Holders of at least 25% in aggregate principal amount of the Notes then
outstanding;

                  (e) a default occurs under any mortgage, indenture or
instrument under which there may be issued or by which there may be secured or
evidenced any Indebtedness for money borrowed by the Company or any of its
Restricted Subsidiaries (or the payment of which is guaranteed by the Company or
any of its Restricted Subsidiaries) whether such Indebtedness or guarantee now
exists, or is created after the Issue Date, which default (a) is caused by a
failure to pay principal of or premium, if any, or interest on such Indebtedness
prior to the expiration of the grace period provided in such Indebtedness on the
date of such default (a "Payment Default") or (b) results in the acceleration of
such Indebtedness prior to its express maturity and, in each case, the principal

provided that the aggregate of all such unpaid or undischarged judgments exceeds
$5,000,000 (excluding amounts covered by insurance);

                  (g) the Company or any of its Restricted Subsidiaries or any

decree under the Bankruptcy Code that:

                                    (i) is for relief against the Company or any
                  of its Restricted Subsidiaries or any of its Significant
                  Subsidiaries or any group of Subsidiaries that, when taken
                  together, would constitute a Significant Subsidiary, in an
                  involuntary case;

                                    (ii) appoints a Custodian of the Company or

                  together, would constitute a Significant Subsidiary, or for
                  all or substantially all of the property of the Company or any
                  of its Restricted Subsidiaries or any of its Significant

                  (i) except as permitted herein, any Subsidiary Guarantee shall
be held in any judicial proceeding to be unenforceable or invalid or shall cease

acting on behalf of any Guarantor, shall deny or disaffirm its obligations under
its Subsidiary Guarantee (other than by reason of the termination of this
Indenture or the release of any such Subsidiary Guarantee in accordance with
this Indenture).

         In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the Notes pursuant to Section
3.07 hereof, an equivalent premium shall also become and be immediately due and
payable, to the extent permitted by law upon the acceleration of the Notes. If
an Event of Default occurs prior to June 1, 2003 by reason of any willful action
(or inaction) taken (or not taken) by or on behalf of the Company with the
intention of avoiding the prohibition on redemption of the Notes prior to June
1, 2003, then the premium, as discussed below, will become immediately due and
payable to the extent permitted by law upon the acceleration of the Notes. The
premium payable for purposes of this paragraph for each of the years beginning
on June 1, of the years set forth below shall be as set forth in the following
table expressed as a percentage of the amount that would otherwise be due but
for the provisions of this sentence, plus accrued interest, if any, to the date
of payment:

                    2002 ......... 105.250%
</TABLE>

SECTION 6.02        Acceleration.

         If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately. Upon any such
declaration, the Notes shall become due and payable immediately. Notwithstanding
the foregoing, if an Event of Default specified in clause (g) or (h) of Section
6.01 hereof occurs with respect to the Company or any Significant Subsidiary or
any group of Subsidiaries that, taken together, would constitute a Significant
Subsidiary, all outstanding Notes shall be due and payable immediately without
further action or notice. The Holders of at least a majority in aggregate
principal amount of the then outstanding Notes by written notice to the Trustee
may on behalf of all of the Holders rescind an acceleration and its consequences
if the rescission would not conflict with any judgment or decree and if all
existing Events of Default (except nonpayment of principal, interest or
Liquidated Damages that has become due solely because of the acceleration) have
been cured or waived.

SECTION 6.03        Other Remedies.

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

         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 Holder of a Note 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. All remedies are
cumulative to the extent permitted by law.

SECTION 6.04        Waiver of Past Defaults.

         Holders of not less than a majority in aggregate principal amount of
the then outstanding Notes by notice to the Trustee may on behalf of the Holders
of all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of interest or Liquidated Damages, if any, on, or the principal of, the
Notes including in connection with an offer to purchase; provided, however, that
the Holders of a majority in aggregate principal amount of then outstanding
Notes may rescind an acceleration and its consequences, including any related
payment default that resulted from such acceleration, to the extent permitted by
applicable law. Upon any such waiver, such Default shall cease to exist, and



                                       62
<PAGE>   69

any Event of Default arising therefrom shall be deemed to have been cured for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereon.

SECTION 6.05        Control by Majority.

         Holders of a majority in principal amount of the then outstanding Notes
may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability.

SECTION 6.06        Limitation on Suits.

         A Holder of a Note may pursue a remedy with respect to this Indenture
or the Notes only if:

                  (a) the Holder of a Note has previously given to the Trustee
written notice of a continuing Event of Default;

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

                  (c) such Holder of a Note or Holders of Notes offer and, if
requested, provide to the Trustee indemnity satisfactory to the Trustee against
any loss, liability or expense to be incurred in compliance with such request;

                  (d) the Trustee does not comply with the request within 60
days after receipt of the request and the offer and, if requested, the provision
of indemnity; and

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

A Holder of a Note may not use this Indenture to prejudice the rights of another
Holder of a Note or to obtain a preference or priority over another Holder of a
Note or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all of such Holders.

SECTION 6.07        Rights of Holders of Notes to Receive Payment.

         Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium and Liquidated
Damages, if any, and interest on the Note, on or after the respective due dates
expressed in the Note (including in connection with an offer to



                                       63
<PAGE>   70

purchase), 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 6.08        Collection Suit by Trustee.

         If an Event of Default specified in Section 6.01(a) or (b) hereof
occurs and is continuing, the Trustee is authorized to recover judgment in its
own name and as trustee of an express trust against the Company for the whole
amount of principal of, premium and Liquidated Damages, if any, and interest
remaining unpaid on the Notes and interest on overdue principal and, to the
extent lawful, interest and such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09        Trustee May File Proofs of Claim.

         The Trustee is authorized to 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 (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the Notes), its creditors or its property and shall
be entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims and any custodian in any such
judicial proceeding is hereby authorized by each Holder to make such 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 to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 7.07 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall
be secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties that the Holders may be
entitled to receive in such proceeding whether in liquidation or under any plan
of reorganization or arrangement or otherwise. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10        Priorities.

         If the Trustee collects any money pursuant to this Article, it shall
pay out the money in the following order:



                                       64
<PAGE>   71

         First: to the Trustee, its agents and attorneys for amounts due under
Section 7.07 hereof, including payment of all compensation, expense, and
liabilities incurred, and all advances made, by the Trustee and the costs and
expenses of collection;

         Second: to Holders of Notes for amounts due and unpaid on the Notes for
principal, premium and Liquidated Damages, if any, and interest, ratably,
without preference or priority of any kind, according to the amounts due and
payable on the Notes for principal, premium and Liquidated Damages, if any and
interest, respectively; and

         Third: to the Company or to such party as a court of competent
jurisdiction shall direct.

         The Trustee may fix a record date and payment date for any payment to
Holders of Notes pursuant to this Section 6.10.

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 a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the cost 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 of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more
than 10% in principal amount of the then outstanding Notes.

                                   ARTICLE VII

                                     TRUSTEE

SECTION 7.01        Duties of Trustee.

                  (a) If an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

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

                           (i) The Trustee need perform only those duties that
         are specifically set forth in this Indenture and the TIA and no others,
         and no implied covenants or obligations shall be read into this
         Indenture against the Trustee. To the extent of any conflict between
         the duties of the Trustee hereunder and under the TIA, the TIA shall
         control.



                                       65
<PAGE>   72

                           (ii) 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, the Trustee shall examine the certificates and
         opinions to determine whether or not they conform to the requirements
         of this Indenture (but need not confirm or investigate the accuracy of
         mathematical calculations or other facts stated therein).

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

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

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

                           (iii) 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 6.05 hereof.

                  (d) Whether or not therein expressly so provided, every
provision of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b), and (c) of this Section.

                  (e) No provision of this Indenture shall require the Trustee
to expend or risk its own funds or incur any liability. The Trustee shall be
under no obligation to exercise any of its rights and powers under this
Indenture at the request of any Holders, unless such Holder shall have offered
to the Trustee security and indemnity satisfactory to it against any loss,
liability or expense.

                  (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.
Money held in trust by the Trustee need not be segregated from other funds
except to the extent required by law.

SECTION 7.02        Rights of Trustee.

                  (a) The Trustee may conclusively rely upon any document
(whether in its original or facsimile form) 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 or both. The Trustee
shall not be liable for any action it takes or omits to take in good faith in
reliance on such Officers' Certificate or Opinion of Counsel. The



                                       66
<PAGE>   73

Trustee may consult with counsel of its selection and the advice of such counsel
or any Opinion of Counsel shall be full and complete authorization and
protection from liability in respect of any action taken, suffered or omitted by
it hereunder in good faith and in reliance thereon.

                  (c) The Trustee may act through its attorneys and 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 that it believes to be authorized or within the
rights or powers conferred upon it by this Indenture.

any demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

                  (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 unless such Holders shall have offered to the
Trustee reasonable security or indemnity against the costs, expenses and
liabilities (including fees and expenses of its agents and counsel) that might
be incurred by it in compliance with such request or direction.

SECTION 7.03        Individual Rights of Trustee.

         The Trustee, any Paying Agent, any authenticating agent or registrar in
its individual or any other capacity may become the owner or pledgee of Notes
and may otherwise deal with the Company or any Affiliate of the Company with the
same rights it would have if it were not Trustee. However, in the event that the
Trustee acquires any conflicting interest it must eliminate such conflict within
90 days, apply to the SEC for permission to continue as trustee or resign. Any
Agent may do the same with like rights and duties. The Trustee is also subject
to Sections 7.10 and 7.11 hereof.

SECTION 7.04        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 Company's use of the proceeds from the Notes or any money
paid to the Company or upon the Company's direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.


                                       67
<PAGE>   74
SECTION 7.05        Notice of Defaults.

         If a Default or Event of Default occurs and is continuing and if it is
actually known to a Responsible Officer of the Trustee, the Trustee shall mail
to Holders of Notes a notice of the Default or Event of Default within 90 days
after it occurs. Except in the case of a Default or Event of Default in payment
of principal of, or interest or Liquidated Damages, if any, on any Note, the
Trustee may withhold the notice if and so long as a committee of its Responsible
Officers in good faith determines that withholding the notice is in the
interests of the Holders of the Notes.

SECTION 7.06        Reports by Trustee to Holders of the Notes.

         Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, and for so long as Notes remain outstanding, the
Trustee shall mail to the Holders of the Notes a brief report dated as of such
reporting date that complies with TIA Section 313(a) (but if no event described 
in TIA Section 313(a) has occurred within the twelve months preceding the 
reporting date, no report need be transmitted). The Trustee also shall comply 
with TIA Section 313(b)(2). The Trustee shall also transmit by mail all reports
as required by TIA Section 313(c).

         A copy of each report at the time of its mailing to the Holders of
Notes shall be mailed to the Company and filed with the SEC and each stock
exchange on which the Notes are listed in accordance with TIA Section 313(d). 
The Company shall promptly notify the Trustee when the Notes are listed on any 
stock exchange or delisted therefrom.

SECTION 7.07        Compensation and Indemnity.

         The Company shall pay to the Trustee from time to time such
compensation for its acceptance of this Indenture and services hereunder as the
parties shall agree from time to time. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Company
shall reimburse the Trustee promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by it in addition to the
compensation for its services. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.
The Company shall indemnify each of the Trustee and any predecessor Trustee
against any and all losses, liabilities, claims, damages or expenses (including
taxes other than taxes based upon the income or gross receipts of the Trustee)
incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture, including the costs and
expenses of enforcing this Indenture against the Company (including this Section
7.07) and defending itself against any claim (whether asserted by the Company or
any Holder or any other person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder, except to the extent any
such loss, liability, claim, damage or expense may be attributable to its
negligence or bad faith. The Trustee shall notify the Company promptly of any
claim for which it may seek indemnity. Failure by the Trustee to so notify the
Company shall not relieve the Company of its obligations hereunder. The Company
shall defend the claim and the Trustee shall cooperate in the 

                                       68

<PAGE>   75


defense. The Trustee may have separate counsel and the Company shall pay the
reasonable fees and expenses of such counsel. The Company need not pay for any
settlement made without its consent, which consent shall not be unreasonably
withheld.

         The obligations of the Company under this Section 7.07 shall survive
the satisfaction and discharge of this Indenture.

         To secure the Company'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, except that held in trust to pay principal and
interest on particular Notes. Such Lien shall survive the satisfaction and
discharge of this Indenture.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(g) or (h) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under the
Bankruptcy Code.

         The Trustee shall comply with the provisions of TIA Section 313(b)(2)
to the extent applicable.

SECTION 7.08        Replacement of Trustee.

         A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

         The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company. The Holders of Notes of a
majority in principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Company in writing. The Company may

continue for the benefit of the retiring Trustee.

                                  ARTICLE VIII

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 8.01        Option to Effect Legal Defeasance or Covenant Defeasance.

         The Company may, at the option of its Board of Directors evidenced by a
resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article 8.

SECTION 8.02        Legal Defeasance and Discharge.

         Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Company shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be deemed to have been
discharged from its obligations with respect to all outstanding Notes on the
date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance") except for (i) the rights of Holders of outstanding Notes to
receive payments in respect of the principal of, premium, if any, and interest
and Liquidated Damages, if any, on such Notes when such payments are due from
the trust referred to below, (ii) the Company's obligations with respect to the
Notes concerning issuing temporary Notes, registration of Notes, mutilated,
destroyed, lost or stolen Notes and the maintenance of an office or agency for
payment and money for security payments held in trust, (iii) the rights, powers,
trusts, duties and immunities of the Trustee, and the Company's obligations in
connection therewith and (iv) the Legal Defeasance provisions of this Indenture.
For this purpose, Legal Defeasance means that the Company shall be deemed to
have paid and discharged the entire Indebtedness represented by the outstanding
Notes, which shall thereafter be deemed to be "outstanding" only for the
purposes of Section 8.05 hereof and the other Sections of this Indenture
referred to in (a) and (b) below, and to have satisfied all its other
obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder: (a) the rights of Holders of
outstanding Notes to receive solely from the trust fund described in Section
8.04 hereof, and as more fully set forth in such Section, payments in respect of
the principal of, premium, if any, and interest and Liquidated Damages, if any,
on such Notes when such payments are due, (b) the Company's obligations with
respect to such Notes under Article 2 and Section 4.02 hereof, (c) the rights,
powers, trusts, duties and immunities of the Trustee hereunder and the Company's
obligations in connection therewith and (d) this Article 8. Subject to
compliance with this Article 8, the Company may exercise its option under this
Section 8.02 notwithstanding the prior exercise of its option under Section 8.03
hereof.

SECTION 8.03        Covenant Defeasance.

         Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be released from its
obligations under the covenants contained in Sections 4.03, 4.04, 4.05, 

                                       71

<PAGE>   78


4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17 and 4.18 hereof,
Article 5 hereof and Section 10.03 hereof with respect to the outstanding Notes
on and after the date the conditions set forth below are satisfied (hereinafter,
"Covenant Defeasance"), and the Notes shall thereafter be deemed not
"outstanding" for the purposes of any direction, waiver, consent or declaration
or act of Holders (and the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "outstanding" for all other purposes
hereunder (it being understood that such Notes shall not be deemed outstanding
for accounting purposes). For this purpose, Covenant Defeasance means that, with
respect to the outstanding Notes, the Company may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such covenant or by reason of any reference in any such
covenant to any other provision herein or in any other document and such
omission to comply shall not constitute a Default or an Event of Default under
Section 6.01 hereof, but, except as specified above, the remainder of this
Indenture and such Notes shall be unaffected thereby. In addition, upon the
Company's exercise under Section 8.01 hereof of the option applicable to this
Section 8.03 hereof, subject to the satisfaction of the conditions set forth in
Section 8.04 hereof, Sections 6.01(c) through 6.01(g) hereof and 6.01(i) hereof
shall not constitute Events of Default.

SECTION 8.04        Conditions to Legal or Covenant Defeasance.

         The following shall be the conditions to the application of either
Section 8.02 or 8.03 hereof to the outstanding Notes:

         In order to exercise either Legal Defeasance or Covenant Defeasance:

                  (a) the Company must irrevocably deposit with the Trustee, in
trust, for the benefit of the Holders, cash in U.S. dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent public
accountants, to pay the principal of, premium, if any, and interest and
Liquidated Damages, if any, on the outstanding Notes on the stated maturity or
on the applicable redemption date, as the case may be, and the Company must
specify whether the Notes are being defeased to maturity or to a particular
redemption date;

                  (b) in the case of an election under Section 8.02 hereof, the
Company shall have delivered to the Trustee an Opinion of Counsel in the United
States reasonably acceptable to the Trustee confirming that (A) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (B) 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 Opinion of Counsel shall confirm that, the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Legal Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Legal Defeasance had not occurred;

                                       72

<PAGE>   79


                  (c) in the case of an election under Section 8.03 hereof, the
Company shall have delivered to the Trustee an Opinion of Counsel in the United
States reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Covenant Defeasance had not occurred;

                  (d) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit) or insofar
as Section 6.01(g) or 6.01(h) hereof is concerned, at any time in the period
ending on the 91st day after the date of deposit;

                  (e) such Legal Defeasance or Covenant Defeasance will not
result in a breach or violation of, or constitute a default under, any material
agreement or instrument (other than this Indenture) to which the Company or any
of its Restricted Subsidiaries is a party or by which the Company or any of its
Restricted Subsidiaries is bound;

                  (f) the Company shall have delivered to the Trustee an Opinion
of Counsel to the effect that on the 91st day following the deposit, the trust
funds will not be subject to the effect of any applicable bankruptcy,
insolvency, reorganization or similar laws affecting creditors' rights
generally;

                  (g) the Company shall have delivered to the Trustee an
Officers' Certificate stating that the deposit was not made by the Company with
the intent of preferring the Holders of Notes over the other creditors of the
Company with the intent of defeating, hindering, delaying or defrauding
creditors of the Company or others; and

                  (h) the Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent provided for or relating to the Legal Defeasance or the
Covenant Defeasance have been complied with.

SECTION 8.05        Deposited Money and Government Securities to be Held in
                    Trust; Other Miscellaneous Provisions.

         Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as Paying Agent) as the
Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium, if any, and interest and
Liquidated Damages, if any, but such money need not be segregated from other
funds except to the extent required by law.

                                       73

<PAGE>   80


         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Notes.

         Anything in this Article 8 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or non-callable Government Securities held by it as provided
in Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
8.04(a) hereof), are in excess of the amount thereof that would then be required
to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

SECTION 8.06        Repayment to Company.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of, premium, if any,
or interest and Liquidated Damages, if any, on any Note and remaining unclaimed
for two years after such principal, and premium, if any, or interest and
Liquidated Damages, if any, has become due and payable shall be paid to the
Company on its request or (if then held by the Company) shall be discharged from
such trust; and the Holder of such Note shall thereafter, as a secured creditor,
look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in the New York
Times and The Wall Street Journal (national edition), notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such notification or publication, any
unclaimed balance of such money then remaining will be repaid to the Company.

SECTION 8.07        Reinstatement.

         If the Trustee or Paying Agent is unable to apply any U.S. dollars or
non-callable Government Securities in accordance with Section 8.02 or 8.03
hereof, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 8.02 or 8.03
hereof, as the case may be; provided, however, that, if the Company makes any
payment of principal of, premium, if any, or interest and Liquidated Damages, if
any, on any Note following the reinstatement of its obligations, the Company
shall be subrogated to the rights of the Holders of such Notes to receive such
payment from the money held by the Trustee or Paying Agent.

                                   ARTICLE IX

                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01        Without Consent of Holders of Notes.

         Notwithstanding Section 9.02 hereof, the Company and the Trustee may
amend or supplement this Indenture or the Notes without the consent of any
Holder of a Note:

                  (a)      to cure any ambiguity, defect or inconsistency;

                  (b) to provide for uncertificated Notes in addition to or in
place of certificated Notes or to alter the provisions of Article 2 hereof
(including the related definitions) in a manner that does not materially
adversely affect any Holder;

                  (c) to provide for the assumption of the Company's obligations
to the Holders of the Notes in the case of a merger, consolidation or sale of
assets of the Company pursuant to Article 5 hereof or of any Guarantor pursuant
to Article 10 hereof or to add any Person as a Guarantor hereunder;

                  (d) to make any change that would provide any additional
rights or benefits to the Holders of the Notes or that does not adversely affect
the legal rights hereunder of any such Holder; or

                  (e) to comply with requirements of the SEC in order to effect
or maintain the qualification of this Indenture under the TIA or to allow any
Guarantor to guarantee the Notes.

         Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon receipt by the Trustee of the documents described in Section
7.02 hereof, the Trustee shall join with the Company in the execution of any
amended or supplemental Indenture authorized or permitted by the terms of this
Indenture and to make any further appropriate agreements and stipulations that
may be therein contained, but the Trustee shall not be obligated to enter into
such amended or supplemental Indenture that affects its own rights, duties,
liabilities or immunities under this Indenture or otherwise.

SECTION 9.02        With Consent of Holders of Notes.

         Except as provided below in this Section 9.02, the Company and the
Trustee may amend or supplement this Indenture (including Sections 3.09, 4.10
and 4.15 hereof) and the Notes may be amended or supplemented with the consent
of the Holders of at least a majority in principal amount of the Notes then
outstanding (including, without limitation, consents obtained in connection with
a tender offer or exchange offer for the Notes), and, subject to Sections 6.04
and 6.07 hereof, any existing Default or Event of Default (other than a Default
or Event of Default in the payment of the 

                                       75

<PAGE>   82


principal of, premium, if any, or interest and Liquidated Damages, if any, on
the Notes, except a payment default resulting from an acceleration that has been
rescinded) or compliance with any provision of this Indenture or the Notes may
be waived with the consent of the Holders of a majority in principal amount of
the then outstanding Notes (including consents obtained in connection with a
tender offer or exchange offer for the Notes).

         Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by
a Responsible Officer of the Trustee of the documents described in Section 7.02
hereof, the Trustee shall join with the Company in the execution of such amended
or supplemental Indenture unless such amended or supplemental Indenture affects
the Trustee's own rights, duties, liabilities or immunities under this Indenture
or otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such amended or supplemental Indenture.

         It shall not be necessary for the consent of the Holders of Notes under
this Section 9.02 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

         After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Notes then outstanding may waive
compliance in a particular instance by the Company with any provision of this
Indenture or the Notes. However, without the consent of each Holder affected, an
amendment or waiver may not (with respect to any Notes held by a nonconsenting
Holder):

                  (a) reduce the principal amount of Notes whose Holders must
consent to an amendment, supplement or waiver of any provision of this
Indenture, the Notes or any Subsidiary Guarantee;

                  (b) reduce the principal of or change the fixed maturity of
any Note or alter or waive in any manner that adversely affects the rights of
any Holder of Notes any of the provisions with respect to the redemption of the
Notes except as provided above with respect to Sections 3.09, 4.10 and 4.15
hereof and the related definitions;

                  (c) reduce the rate of or change the time for payment of
interest, including default interest, or Liquidated Damages, if any, on any
Note;

                  (d) waive a Default or Event of Default in the payment of
principal of or premium, if any, or interest or Liquidated Damages, if any, on
the Notes (except a rescission of 

                                       76

<PAGE>   83


acceleration of the Notes by the Holders of at least a majority in aggregate
principal amount of the then outstanding Notes and a waiver of the payment
default that resulted from such acceleration);
                                              
                  (e) make any Note payable in money other than that stated in
the Notes;

                  (f) make any change that adversely affects the rights of any
Holder of Notes in the provisions of this Indenture relating to waivers of past
Defaults or make any change to the rights of Holders of Notes to receive
payments of principal of or interest or Liquidated Damages, if any, on the
Notes;

                  (g) waive a redemption payment with respect to any Note (other
than a payment required by Sections 3.09, 4.10 and 4.15 hereof).

                  (h) make any change in Section 6.04 or 6.07 hereof or in the
foregoing amendment and waiver provisions; or

SECTION 9.03        Compliance with Trust Indenture Act.

         Every amendment or supplement to this Indenture or the Notes shall be
set forth in a amended or supplemental Indenture that complies with the TIA as
then in effect.

SECTION 9.04        Revocation and Effect of Consents.

         Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note, even if notation of the consent is not
made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment becomes
effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

SECTION 9.05        Notation on or Exchange of Notes.

         The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company, in
exchange for all Notes, may issue and the Trustee shall authenticate new Notes
that reflect the amendment, supplement or waiver.

         Failure to make the appropriate notation or issue a new Note shall not
affect the validity and effect of such amendment, supplement or waiver.

<PAGE>   84


SECTION 9.06        Trustee to Sign Amendments, Etc.

         The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Trustee
may, but shall not be obligated to, enter into any such supplemental indenture
which affects the Trustee's own rights, duties, liabilities or immunities under
this Indenture or otherwise. The Company may not sign an amendment or
supplemental Indenture until the Board of Directors approves it. In executing
any amended or supplemental indenture, the Trustee shall be entitled to receive
and (subject to Section 7.01 hereof) shall be fully protected in relying upon,
an Officers' Certificate and an Opinion of Counsel stating that the execution of
such amended or supplemental indenture is authorized or permitted by this
Indenture.

                                    ARTICLE X

                                   GUARANTEES

SECTION 10.01       Subsidiary Guarantees.

         Subject to Section 10.05 hereof, any Restricted Subsidiary that becomes
a Guarantor shall, jointly and severally, unconditionally guarantee to each
Holder of a Note authenticated and delivered by the Trustee and to the Trustee
and its successors and assigns, the Notes and the Obligations of the Company
hereunder and thereunder, that:

                  (a) the principal of, premium, if any, interest and Liquidated
Damages, if any, on the Notes will be promptly paid in full when due, subject to
any applicable grace period, whether at maturity, by acceleration, redemption or
otherwise, and interest on the overdue principal, premium, if any (to the extent
permitted by law), interest on any interest, if any, and Liquidated Damages, if
any, on the Notes, and all other payment Obligations of the Company to the
Holders or the Trustee hereunder or thereunder will be promptly paid in full and
performed, all in accordance with the terms hereof and thereof; and

                  (b) in case of any extension of time of payment or renewal of
any Notes or any of such other Obligations, the same will be promptly paid in
full when due or performed in accordance with the terms of the extension or
renewal, subject to any applicable grace period, whether at stated maturity, by
acceleration, redemption or otherwise.

         Failing payment when so due of any amount so guaranteed or any
performance so guaranteed for whatever reason, the Guarantors will be jointly
and severally obligated to pay the same immediately. An Event of Default under
this Indenture or the Notes shall constitute an event of default under the
Subsidiary Guarantees, and shall entitle the Holders to accelerate the
Obligations of the Guarantors hereunder in the same manner and to the same
extent as the Obligations of the Company. The Guarantors shall agree that their
Obligations hereunder shall be unconditional, irrespective of the validity or
enforceability of the Notes or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder with respect to any
provisions hereof or 

                                       78

thereof, the recovery of any judgment against the Company, any action to enforce
the same or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a Guarantor. Each Guarantor shall waive
diligence, presentment, demand of payment, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever
and shall covenant that its Subsidiary Guarantee will not be discharged except
by complete performance of the Obligations contained in the Notes and this
Indenture. If any Holder or the Trustee is required by any court or otherwise to
return to the Company, the Guarantors, or any Note Custodian, Trustee,
liquidator or other similar official acting in relation to either the Company or
the Guarantors, any amount paid by the Company or any Guarantor to the Trustee
or such Holder, the Subsidiary Guarantee, to the extent theretofore discharged,
shall be reinstated in full force and effect. Each Guarantor shall agree that it
shall not be entitled to, and shall waive, any right to exercise any right of
subrogation in relation to the Holders in respect of any Obligations guaranteed
by the Subsidiary Guarantee, except as provided under Section 10.05 hereof. Each
Guarantor shall further agree that, as between the Guarantors, on the one hand,
and the Holders and the Trustee, on the other hand, (x) the maturity of the
Obligations guaranteed by the Subsidiary Guarantee may be accelerated as
provided in Article 6 hereof for the purposes of its Subsidiary Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Obligations guaranteed thereby, and (y) in the
event of any declaration of acceleration of such Obligations as provided in
Article 6 hereof, such Obligations (whether or not due and payable) shall
forthwith become due and payable by each Guarantor for the purpose of its
Subsidiary Guarantee. The Guarantors shall have the right to seek contribution
from any non-paying Guarantor pursuant to Section 10.05 after the Notes and the
Obligations hereunder shall have been paid in full to the Holders under the
Subsidiary Guarantees.

SECTION 10.02       Execution and Delivery of Subsidiary Guarantee.

         To evidence its Subsidiary Guarantee set forth in Section 10.01 hereof,
each Guarantor shall execute and deliver a supplemental indenture substantially
in the form of Exhibit D hereto, which supplemental indenture shall be entered
into in accordance with Section 4.16 hereof and shall be executed on behalf of
such Guarantor, by manual or facsimile signature, by an Officer of such
Guarantor.

         Each Guarantor shall agree that its Subsidiary Guarantee set forth in
Section 10.01 hereof shall remain in full force and effect notwithstanding any
failure to endorse on each Note a notation of such Subsidiary Guarantee.

         If an officer who shall have signed this Indenture or a supplemental
indenture no longer holds that office at the time the Trustee authenticates the
Note on which a Subsidiary Guarantee is endorsed, the Subsidiary Guarantee shall
be valid nevertheless.

         The delivery of any Note by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee set
forth in this Indenture on behalf of the Guarantors.

SECTION 10.03       Guarantors May Consolidate, Etc., on Certain Terms.

                  (a) Except as set forth in Articles 4 and 5 hereof, nothing
contained in this Indenture shall prohibit a merger between a Guarantor and
another Guarantor or a merger between a Guarantor and the Company.

                  (b) No Guarantor shall consolidate with or merge with or into
(whether or not such Guarantor is the surviving Person) or sell all or
substantially all of its assets to, another corporation, Person or entity
whether or not affiliated with such Guarantor unless, subject to the following
paragraph, (i) the Person formed by or surviving any such merger or
consolidation, or to which such sale of assets shall have been made (if other
than such Guarantor) assumes all the Obligations of such Guarantor, pursuant to
a supplemental indenture substantially in the form of Exhibit D hereto, under
this Indenture; (ii) immediately after giving effect to such transaction, no
Default or Event of Default exists; (iii) such Guarantor, or any Person formed
by or surviving any such consolidation or merger, would have Consolidated Net
Worth (immediately after giving effect to such transaction) equal to or greater
than the Consolidated Net Worth of such Guarantor immediately preceding the
transaction; and (iv) except in the case of the merger of a Guarantor with or
into another Guarantor or the Company, the Company would be permitted by virtue
of the Company's pro forma Fixed Charge Coverage Ratio, immediately after giving
effect to such transaction, to incur at least $1.00 of additional Indebtedness
pursuant to the Fixed Charge Coverage Ratio test set forth in the first
paragraph of Section 4.09 hereof.

         Notwithstanding the foregoing paragraph, (i) any Guarantor may
consolidate with, merge into or transfer all or a part of its properties and
assets to the Company or any other Guarantor and (ii) any Guarantor may merge
with a Wholly Owned Restricted Subsidiary of the Company that has no significant
assets or liabilities and was incorporated solely for the purpose of
reincorporating or redomesticating such Guarantor in another State of the United
States or, if such Guarantor was organized under the laws of a jurisdiction
other than a State of the United States, in any foreign country that is a member
of the OECD; provided that, in each case, such merged entity continues to be a
Guarantor.

                  (c) In the case of any such consolidation, merger, sale or
conveyance and upon the assumption by the successor Person, by supplemental
indenture, executed and delivered to the Trustee and substantially in the form
of Exhibit D hereto, of the Subsidiary Guarantee endorsed upon the Notes and the
due and punctual performance of all of the covenants and conditions of this
Indenture to be performed by the Guarantor, such successor Person shall succeed
to and be substituted for the Guarantor with the same effect as if it had been
named herein as a Guarantor. Such successor Person thereupon may cause to be
signed any or all of the Subsidiary Guarantees to be endorsed upon all of the
Notes issuable hereunder which theretofore shall not have been signed by the
Company and delivered to the Trustee. All of the Subsidiary Guarantees so issued
shall in all respects have the same legal rank and benefit under this Indenture
as the Subsidiary Guarantees theretofore and thereafter issued in accordance
with the terms of this Indenture as though all of such Subsidiary Guarantees had
been issued at the date of the execution hereof.

SECTION 10.04       Releases Following Release Under All Indebtedness or Sale of
                    Assets.

         In the event of (i) the release by the lenders under all Indebtedness 
of the Company of all guarantees of a Guarantor and all Liens on the property
and assets of such Guarantor relating to such Indebtedness, or (ii) a sale or
other disposition of all of the assets of any Guarantor, by way of merger,
consolidation or otherwise, or a sale or other disposition of all of the capital
stock of any Guarantor in compliance with the Indenture to any entity that is
not the Company or a Subsidiary, then such Guarantor (in the event of a sale or
other disposition, by way of such a merger, consolidation or otherwise, of all
of the capital stock of such Guarantor), or the Person acquiring the property
(in the event of such a sale or other disposition of all of the assets of such
Guarantor), will be released and relieved of any obligations under its
Subsidiary Guarantee; provided, however, that any such termination shall occur
only to the extent that all obligations of such Guarantor under such
Indebtedness and all of its guarantees of, and under all of its pledges of
assets or other security interests which secure, Indebtedness of the Company
shall also terminate upon such release, sale or transfer and, in the event of
any sale or other disposition, that the Net Proceeds of such sale or other
disposition are applied in accordance with Section 4.10 hereof. Upon delivery by
the Company to the Trustee of an Officers' Certificate to the effect of the
foregoing, the Trustee shall execute any documents reasonably required in order
to evidence the release of any Guarantor from its Obligation under its
Subsidiary Guarantee. Any Guarantor not released from its Obligations under its
Subsidiary Guarantee shall remain liable for the full amount of principal of,
premium, if any, interest and Liquidated Damages, if any, on the Notes and for
the other Obligations of such Guarantor under this Indenture as provided in this
Article 10.

SECTION 10.05       Limitation on Guarantor Liability; Contribution.

         For purposes hereof, each Guarantor's liability shall be limited to the
lesser of (i) the aggregate amount of the Obligations of the Company under the
Notes and this Indenture and (ii) the amount, if any, which would not have (A)
rendered such Guarantor "insolvent" (as such term is defined in the Bankruptcy
Code and in the Debtor and Creditor Law of the State of New York) or (B) left
such Guarantor with unreasonably small capital at the time its Subsidiary
Guarantee of the Notes was entered into; provided that, it will be a presumption
in any lawsuit or other proceeding in which a Guarantor is a party that the
amount guaranteed pursuant to the Subsidiary Guarantee is the amount set forth
in clause (i) above unless any creditor, or representative of creditors of such
Guarantor, or debtor in possession or trustee in bankruptcy of the Guarantor,
otherwise proves in such a lawsuit that the aggregate liability of the Guarantor
is the amount set forth in clause (ii) above. In making any determination as to
solvency or sufficiency of capital of a Guarantor in accordance with the
previous sentence, the right of such Guarantor to contribution from other
Guarantors as set forth below, and any other rights such Guarantor may have,
contractual or otherwise, shall be taken into account.

                                                                    
         In order to provide for just and equitable contribution among the
Guarantors, the Guarantors shall agree, inter se, that in the event any payment
or distribution is made by any Guarantor (a "Funding Guarantor") under its
Subsidiary Guarantee, such Funding Guarantor shall be entitled to a contribution
from all other Guarantors in a pro rata amount based on the Adjusted Net Assets
of

                                       81

<PAGE>   88


each Guarantor (including the Funding Guarantor) for all payments, damages
and expenses incurred by that Funding Guarantor in discharging the Company's
obligations with respect to the Notes or any other Guarantor's Obligations with
respect to its Subsidiary Guarantee.

SECTION 10.06       Trustee to Include Paying Agent.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article 10 shall in each case (unless the context shall
otherwise require) be construed as extending to and including such Paying Agent
within its meaning as fully and for all intents and purposes as if such Paying
Agent were named in this Article 10 in place of the Trustee.

on the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date; provided, further, that
the first Interest Payment Date shall be December 1, 1998. The Company shall pay
interest (including postpetition interest in any proceeding under the Bankruptcy
Code) on overdue principal and premium, if any, from time to time on demand at
the rate borne on the Notes; it shall pay interest (including post-petition
interest in any proceeding under the Bankruptcy Code) on overdue installments of
interest and Liquidated Damages (without regard to any applicable grace periods)
from time to time on demand at the same rate to the extent lawful. Interest will
be computed on the basis of a 360-day year of twelve 30-day months.

         2. Method of Payment. The Company will pay interest on the Notes
(except defaulted interest) and Liquidated Damages to the Persons who are
registered Holders of Notes at the close of business on the May 15 or November
15 next preceding the Interest Payment Date, even if such Notes are canceled
after such record date and on or before such Interest Payment Date, except as
provided in Section 2.12 of the Indenture with respect to defaulted interest.
The Notes will be payable as to principal, premium and Liquidated Damages, if
any, and interest at the office or agency of the Company maintained for such
purpose within the City and State of New York, or, at the option of the Company,
payment of interest and Liquidated Damages may be made by check mailed to the
Holders at their addresses set forth in the register of Holders, and provided
that payment by wire transfer of immediately available funds will be required
with respect to principal of and interest, premium and Liquidated Damages on,
all Global Notes and all other Notes the Holders of which shall have provided
wire transfer instructions to the Company or the Paying Agent. Such payment
shall be in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts.

         3. Paying Agent and Registrar. Initially, State Street Bank and Trust
Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice
to any Holder. The Company or any of its Subsidiaries may act in any such
capacity.

         4. Indenture. The Company issued the Notes under an Indenture dated as
of June 8, 1998 ("Indenture") between the Company 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, as amended (15 U.S.
Code Sections 77aaa-77bbbb). The Notes are subject to all such terms, and 
Holders are referred to the Indenture and such Act for a statement of such 
terms. To the extent any provision of this Note conflicts with the express 
provisions of the Indenture, the provisions of the Indenture shall govern and be
controlling. The Notes are obligations of the Company limited to $200,000,000 in
aggregate principal amount, $130,000,000 of which will be issued in the 
Offering.

         5. Optional Redemption.

                  (a) Except as set forth in subparagraph (b) of this paragraph
5 and paragraph 8 below, the Notes shall not be redeemable at the Company's
option prior to June 1, 2003. Thereafter, the Notes will be subject to
redemption at any time at the option of the Company in whole or in part, at the
redemption prices (expressed as percentages of principal amount) set forth below
plus accrued and unpaid interest and Liquidated Damages thereon, if any, to the
applicable redemption date, if redeemed during the twelve-month period beginning
on June 1 of the years indicated below:

</TABLE>

                  (b) Notwithstanding the foregoing, at any time prior to June
1, 2001, the Company may on any one or more occasions redeem an aggregate of up
to 35% of the original aggregate principal amount of Notes at a redemption price
of 108.75% of the principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages thereon, if any, to the redemption date, with the net cash
proceeds of any Public Equity Offering; provided that at least 65% of the
original aggregate principal amount of Notes originally issued on the Issue Date
remain outstanding immediately after each occurrence of such redemption; and
provided, further, that each such redemption shall occur within 60 days of the
date of the closing of such Public Equity Offering.

         6. Mandatory Redemption. Except as set forth in paragraph 7 below, the
Company shall not be required to make mandatory redemption payments with respect
to the Notes.

<PAGE>   96



         7. Repurchase at Option of Holder.

                  (a) Upon the occurrence of a Change of Control, each Holder of
Notes will have the right to require the Company to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of such Holder's Notes
pursuant to the offer described below (the "Change of Control Offer") at an
offer price in cash equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest and Liquidated Damages thereon, if any, to the date
of purchase (the "Change of Control Payment"). Within 10 days following any
Change of Control, the Company shall mail a notice to each Holder setting forth
the procedures governing the Change of Control Offer as by the Indenture.

                  (b) If the Company or a Restricted Subsidiary consummates any
Asset Sales and the aggregate amount of Excess Proceeds exceeds $10,000,000, the
Company shall commence an offer to all Holders of Notes (an "Asset Sale Offer")
pursuant to Section 3.09 of the Indenture (pro rata in proportion to outstanding
Indebtedness that is pari passu with the Notes that require asset sale offers)
to purchase the maximum principal amount of Notes that may be purchased out of
the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the
principal amount thereof plus accrued and unpaid interest and Liquidated Damages
thereon, if any, to the date of purchase, in accordance with the procedures set
forth in the Indenture. To the extent that the aggregate amount of Notes
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Company (or such Restricted Subsidiary) may use such deficiency for general
corporate purposes. If the aggregate principal amount of Notes surrendered by
Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select
the Notes to be purchased on a pro rata basis. Holders of Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Company prior to any related purchase date and may elect to have such Notes
purchased by completing the form entitled "Option of Holder to Elect Purchase"
on the reverse of the Notes.

         8. Notice of Redemption. Notice of redemption will be mailed at least
30 days but not more than 60 days before the redemption date to each Holder
whose Notes are to be redeemed at its registered address. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of
$1,000, unless all of the Notes held by a Holder are to be redeemed. On and
after the redemption date, interest and Liquidated Damages, if any, cease to
accrue on Notes or portions thereof called for redemption.

         9. Denominations, Transfer, Exchange. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, it need not
exchange or register the transfer of any Notes for a period of 15

                                      A1-4

<PAGE>   97


days before a selection of Notes to be redeemed or during the period between a
record date and the corresponding Interest Payment Date.

         10. Persons Deemed Owners. The registered Holder of a Note may be
treated as its owner for all purposes.

         11. Amendment, Supplement and Waiver. Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Notes, and any existing default or compliance with any provision of the
Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes. Without the consent
of any Holder of a Note, the Indenture or the Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for the assumption of the Company's obligations to Holders of the Notes
in case of a merger or consolidation or to add any Person as a Guarantor, to
make any change that would provide any additional rights or benefits to the
Holders of the Notes or that does not adversely affect the legal rights under
the Indenture of any such Holder, or to comply with the requirements of the SEC
in order to effect or maintain the qualification of the Indenture under the TIA.

         12. Defaults and Remedies. Events of Default include: (a) default in
the payment when due of interest on, or Liquidated Damages with respect to, the
Notes and such default continues for a period of 30 days; (b) default in the
payment when due of principal of or premium, if any, on the Notes when the same
becomes due and payable at maturity, upon redemption (including in connection
with an offer to purchase) or otherwise; (c) failure by the Company to comply
with any of the provisions of Section 5.01 of the Indenture; (d) failure by the
Company or any of its Restricted Subsidiaries to comply with any of the
provisions of Section 4.07, 4.09, 4.10 or 4.15 of the Indenture; (e) failure by
the Company or any of its Restricted Subsidiaries to observe or perform any
other covenant, representation, warranty or other agreement in the Indenture or
the Notes for 30 days after notice to the Company by the Trustee or the Holders
of at least 25% in aggregate principal amount of the Notes then outstanding; (f)
a default occurs under any mortgage, indenture or instrument under which there
may be issued or by which there may be secured or evidenced any Indebtedness for
money borrowed by the Company or any of its Restricted Subsidiaries (or the
payment of which is guaranteed by the Company or any of its Restricted
Subsidiaries), whether such Indebtedness or guarantee now exists, or is created
after the Issue Date (a) is caused by a failure to pay principal of or premium,
if any, or interest on such Indebtedness prior to the expiration of the grace
period provided in such Indebtedness on the date of such default (a "Payment
Default") or (b) results in the acceleration of such Indebtedness prior to its
express maturity and, in each case, the principal amount of any such
Indebtedness, together with the principal amount of any other such Indebtedness
under which there has been a Payment Default or the maturity of which has been
so accelerated, aggregates without duplication $5,000,000 or more and such
default shall not have been cured or acceleration rescinded within five Business
Days after such occurrences; (g) a final judgment or final judgments for the
payment of money are entered by a court or courts of competent jurisdiction
against the Company or any of its Restricted Subsidiaries or any of its
Significant Subsidiaries and such judgment or judgments remain unpaid or
undischarged for a period (during

                                      A1-5

<PAGE>   98


which execution shall not be effectively stayed) of 60 days, provided that the
aggregate of all such unpaid or undischarged judgments exceeds $5,000,000
(excluding amounts covered by insurance); (h) certain events of bankruptcy or
insolvency with respect to the Company or any of its Restricted Subsidiaries or
any of its Significant Subsidiaries; or (i) except as permitted in the
Indenture, any Subsidiary Guarantee shall be held in any judicial proceeding to
be unenforceable or invalid or shall cease for any reason to be in full force
and effect or any Guarantor, or any Person acting on behalf of any Guarantor,
shall deny or disaffirm its obligations under its Subsidiary Guarantee. If any
Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the then outstanding Notes may declare all the
Notes to be due and payable immediately. Notwithstanding the foregoing, in the
case of an Event of Default arising from certain events of bankruptcy or
insolvency, all outstanding Notes will become due and payable without further
action or notice. Holders may not enforce the Indenture or the Notes except as
provided in the Indenture. Subject to certain limitations, Holders of a majority
in principal amount of the then outstanding Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the
Notes notice of any continuing Default or Event of Default (except a Default or
Event of Default relating to the payment of principal or interest) if it
determines that withholding notice is in their interest. The Holders of a
majority in aggregate principal amount of the Notes then outstanding by notice
to the Trustee may on behalf of the Holders of all of the Notes waive any
existing Default or Event of Default and its consequences under the Indenture
except a continuing Default or Event of Default in the payment of interest on,
or the principal of, the Notes. The Company is required to deliver to the
Trustee annually a statement regarding compliance with the Indenture, and the
Company is required upon becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.

         In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the Notes pursuant to Section
3.07 of the Indenture, an equivalent premium shall also become and be
immediately due and payable, to the extent permitted by law upon the
acceleration of the Notes. If an Event of Default occurs prior to June 1, 2003
by reason of any willful action ( or inaction) taken (or not taken) by or on
behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to June 1, 2003, then the premium, as discussed
below, will become immediately due and payable to the extent permitted by law
upon the acceleration of the Notes. The premium payable for purposes of this
paragraph for each of the years beginning on June 1, of the years set forth
below shall be as set forth in the following table expressed as a percentage of
the amount that would otherwise be due but for the provisions of this sentence,
plus accrued interest, if any, to the date of payment:

         13. Trustee Dealings with Company. The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not the Trustee.

         14. No Recourse Against Others. A director, officer, employee,
incorporator, partner, member or stockholder, of the Company or any Subsidiary
of the Company or any Guarantor, as such, shall not have any liability for any
obligations of the Company under the Notes, the Subsidiary Guarantees or the
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Note waives and
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Notes.

         15. Authentication. This Note shall not be valid until authenticated by
the manual signature of a Responsible Officer of the Trustee or an
authenticating agent.

         16. Abbreviations. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN joint tenants with right of survivorship and
not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to
Minors Act).

         17. Additional Rights of Holders of Restricted Global Notes and
Restricted Definitive Notes. In addition to the rights provided to Holders of
Notes under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of June 8, 1998, between the Company and the parties named on
the signature pages thereof (the "Registration Rights Agreement").

         18. CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

         The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Registration Rights Agreement.

         Capitalized terms used herein shall have the meanings assigned to them
in the indenture referred to below unless otherwise indicated.

         1. Interest. GulfMark Offshore, Inc., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Note at 
8 3/4% per annum from June 8, 1998 until maturity and shall pay the Liquidated
Damages payable pursuant to Section 5 of the Registration Rights Agreement
referred to below. The Company will pay interest and Liquidated Damages
semi-annually in arrears on June 1 and December 1 of each year, or if any such
day is not a Business Day, on the next succeeding Business Day (each an
"Interest Payment Date"). 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 the
date of issuance; provided that if there is no existing Default in the payment
of interest, and if this Note is authenticated between a record date referred to
on the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date; provided, further, that
the first Interest Payment Date shall be December 1, 1998. The Company shall pay
interest (including postpetition interest in any proceeding under the Bankruptcy
Code) on overdue principal and premium, if any, from time to time on demand at
the rate borne on the Notes; it shall pay interest (including post-petition
interest in any proceeding under the Bankruptcy Code) on overdue installments of
interest and Liquidated Damages (without regard to any applicable grace periods)
from time to time on demand at the same rate to the extent lawful. Interest will
be computed on the basis of a 360-day year of twelve 30-day months.

         Until this Regulation S Temporary Global Note is exchanged for one or
more Regulation S Permanent Global Notes, the Holder hereof shall not be
entitled to receive payments of interest hereon; until so exchanged in full,
this Regulation S Temporary Global Note shall in all other respects be entitled
to the same benefits as other Notes under the Indenture.

         2. Method of Payment. The Company will pay interest on the Notes
(except defaulted interest) and Liquidated Damages to the Persons who are
registered Holders of Notes at the close of business on the May 15 or November
15 next preceding the Interest Payment Date, even if such Notes are canceled
after such record date and on or before such Interest Payment Date, except as
provided in Section 2.12 of the Indenture with respect to defaulted interest.
The Notes will be payable as to principal, premium and Liquidated Damages, if
any, and interest at the office or agency of the Company maintained for such
purpose within the City and State of New York, or, at the option of the Company,
payment of interest and Liquidated Damages may be made by check mailed to the
Holders at their addresses set forth in the register of Holders, and provided
that

                                      A2-3

<PAGE>   106


payment by wire transfer of immediately available funds will be required with
respect to principal of and interest, premium and Liquidated Damages on, all
Global Notes and all other Notes the Holders of which shall have provided wire
transfer instructions to the Company or the Paying Agent. Such payment shall be
in such coin or currency of the United States of America as at the time of
payment is legal tender for payment of public and private debts.

         3. Paying Agent and Registrar. Initially, State Street Bank and Trust
Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice
to any Holder. The Company or any of its Subsidiaries may act in any such
capacity.

         4. Indenture. The Company issued the Notes under an Indenture dated as
of June 8, 1998 ("Indenture") between the Company 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, as amended (15 U.S.
Code Sections 77aaa-77bbbb). The Notes are subject to all such terms, and
Holders are referred to the Indenture and such Act for a statement of such
terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be
controlling. The Notes are obligations of the Company limited to $200,000,000 in
aggregate principal amount, $130,000,000 of which will be issued in the
Offering.

         5. Optional Redemption.

                  (a) Except as set forth in subparagraph (b) of this paragraph
5 and paragraph 8 below, the Notes shall not be redeemable at the Company's
option prior to June 1, 2003. Thereafter, the Notes will be subject to
redemption at any time at the option of the Company in whole or in part, at the
redemption prices (expressed as percentages of principal amount) set forth below
plus accrued and unpaid interest and Liquidated Damages thereon, if any, to the
applicable redemption date, if redeemed during the twelve-month period beginning
on June 1 of the years indicated below:

2006 and thereafter..................               100.000%
</TABLE>

                  (b) Notwithstanding the foregoing, at any time prior to June
1, 2001, the Company may on any one or more occasions redeem an aggregate of up
to 35% of the original aggregate principal amount of Notes at a redemption price
of 108.75% of the principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages thereon, if any, to the redemption date, with the net cash
proceeds of any Public Equity Offering; provided that at least 65% of the
original aggregate principal amount of Notes originally issued on the Issue Date
remain outstanding immediately after each occurrence of such redemption; and
provided, further, that each such redemption shall occur within 60 days of the
date of the closing of such Public Equity Offering.

<PAGE>   107



         6. Mandatory Redemption. Except as set forth in paragraph 7 below, the
Company shall not be required to make mandatory redemption payments with respect
to the Notes.

         7. Repurchase at Option of Holder.

                  (a) Upon the occurrence of a Change of Control, each Holder of
Notes will have the right to require the Company to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of such Holder's Notes
pursuant to the offer described below (the "Change of Control Offer") at an
offer price in cash equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest and Liquidated Damages thereon, if any, to the date
of purchase (the "Change of Control Payment"). Within 10 days following any
Change of Control, the Company shall mail a notice to each Holder setting forth
the procedures governing the Change of Control Offer as by the Indenture.

                  (b) If the Company or a Restricted Subsidiary consummates any
Asset Sales and the aggregate amount of Excess Proceeds exceeds $10,000,000, the
Company shall commence an offer to all Holders of Notes (an "Asset Sale Offer")
pursuant to Section 3.09 of the Indenture (pro rata in proportion to outstanding
Indebtedness that is pari passu with the Notes that require asset sales offers)
to purchase the maximum principal amount of Notes that may be purchased out of
the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the
principal amount thereof plus accrued and unpaid interest and Liquidated Damages
thereon, if any, to the date of purchase, in accordance with the procedures set
forth in the Indenture. To the extent that the aggregate amount of Notes
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Company (or such Restricted Subsidiary) may use such deficiency for general
corporate purposes. If the aggregate principal amount of Notes surrendered by
Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select
the Notes to be purchased on a pro rata basis. Holders of Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Company prior to any related purchase date and may elect to have such Notes
purchased by completing the form entitled "Option of Holder to Elect Purchase"
on the reverse of the Notes.

         8. Notice of Redemption. Notice of redemption will be mailed at least
30 days but not more than 60 days before the redemption date (other than in
connection with a Special Redemption) to each Holder whose Notes are to be
redeemed at its registered address. Notes in denominations larger than $1,000
may be redeemed in part but only in whole multiples of $1,000, unless all of the
Notes held by a Holder are to be redeemed. On and after the redemption date,
interest and Liquidated Damages, if any, cease to accrue on Notes or portions
thereof called for redemption.

         9. Denominations, Transfer, Exchange. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note 


                                      A2-5
<PAGE>   108


or portion of a Note selected for redemption, except for the unredeemed portion
of any Note being redeemed in part. Also, it need not exchange or register the
transfer of any Notes for a period of 15 days before a selection of Notes to be
redeemed or during the period between a record date and the corresponding
Interest Payment Date.

         This Regulation S Temporary Global Note is exchangeable in whole or in
part for one or more Global Notes only (i) on or after the termination of the
40-day restricted period (as defined in Regulation S) and (ii) upon presentation
of certificates (accompanied by an Opinion of Counsel, if applicable) required
by Article 2 of the Indenture. Upon exchange of this Regulation S Temporary
Global Note for one or more Global Notes, the Trustee shall cancel this
Regulation S Temporary Global Note.

         10. Persons Deemed Owners. The registered Holder of a Note may be
treated as its owner for all purposes.

         11. Amendment, Supplement and Waiver. Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Notes, and any existing default or compliance with any provision of the
Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes. Without the consent
of any Holder of a Note, the Indenture or the Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for the assumption of the Company's obligations to Holders of the Notes
in case of a merger or consolidation or to add any Person as a Guarantor, to
make any change that would provide any additional rights or benefits to the
Holders of the Notes or that does not adversely affect the legal rights under
the Indenture of any such Holder, or to comply with the requirements of the SEC
in order to effect or maintain the qualification of the Indenture under the TIA.

         12. Defaults and Remedies. Events of Default include: (a) default in
the payment when due of interest on, or Liquidated Damages with respect to, the
Notes and such default continues for a period of 30 days; (b) default in the
payment when due of principal of or premium, if any, on the Notes when the same
becomes due and payable at maturity, upon redemption (including in connection
with an offer to purchase) or otherwise; (c) failure by the Company to comply
with any of the provisions of Section 5.01 of the Indenture; (d) failure by the
Company or any of its Restricted Subsidiaries to comply with any of the
provisions of Sections 4.07, 4.09, 4.10 or 4.15 of the Indenture; (e) failure by
the Company or any of its Restricted Subsidiaries to observe or perform any
other covenant, representation, warranty or other agreement in the Indenture or
the Notes for 30 days after notice to the Company by the Trustee or the Holders
of at least 25% in aggregate principal amount of the Notes then outstanding; (f)
a default occurs under any mortgage, indenture or instrument under which there
may be issued or by which there may be secured or evidenced any Indebtedness for
money borrowed by the Company or any of its Restricted Subsidiaries (or the
payment of which is guaranteed by the Company or any of its Restricted
Subsidiaries), whether such Indebtedness or guarantee now exists, or is created
after the Issue Date (a) is caused by a failure to pay principal of or premium,
if any, or interest on such Indebtedness prior to the expiration of the

                                      A2-6

<PAGE>   109


grace period provided in such Indebtedness on the date of such default (a
"Payment Default") or results in the acceleration of such Indebtedness prior to
its express maturity and, in each case, the principal amount of any such
Indebtedness, together with the principal amount of any other such Indebtedness
under which there has been a Payment Default or the maturity of which has been
so accelerated, aggregates without duplication $5,000,000 or more and such
default shall not have been cured or acceleration rescinded within five Business
Days after such occurrences; (g) a final judgment or final judgments for the
payment of money are entered by a court or courts of competent jurisdiction
against the Company or any of its Restricted Subsidiaries or any of its
Significant Subsidiaries and such judgment or judgments remain undischarged for
a period (during which execution shall not be effectively stayed) of 60 days,
provided that the aggregate of all such unpaid or undischarged judgments exceeds
$5,000,000 (excluding amounts covered by insurance); (h) certain events of
bankruptcy or insolvency with respect to the Company or any of its Restricted
Subsidiaries or any of its Significant Subsidiaries; or (i) except as permitted
in the Indenture, any Subsidiary Guarantee shall be held in any judicial
proceeding to be unenforceable or invalid or shall cease for any reason to be in
full force and effect or any Guarantor, or any Person acting on behalf of any
Guarantor, shall deny or disaffirm its obligations under its Subsidiary
Guarantee. If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately. Notwithstanding the
foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency, all outstanding Notes will become due and payable
without further action or notice. Holders may not enforce the Indenture or the
Notes except as provided in the Indenture. Subject to certain limitations,
Holders of a majority in principal amount of the then outstanding Notes may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of the Notes notice of any continuing Default or Event of
Default (except a Default or Event of Default relating to the payment of
principal or interest) if it determines that withholding notice is in their
interest. The Holders of a majority in aggregate principal amount of the Notes
then outstanding by notice to the Trustee may on behalf of the Holders of all of
the Notes waive any existing Default or Event of Default and its consequences
under the Indenture except a continuing Default or Event of Default in the
payment of interest on, or the principal of, the Notes. The Company is required
to deliver to the Trustee annually a statement regarding compliance with the
Indenture, and the Company is required upon becoming aware of any Default or
Event of Default, to deliver to the Trustee a statement specifying such Default
or Event of Default.

         In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the Notes pursuant to Section
3.07 of the Indenture, an equivalent premium shall also become and be
immediately due and payable, to the extent permitted by law upon the
acceleration of the Notes. If an Event of Default occurs prior to June 1, 2003
by reason of any willful action (or inaction) taken (or not taken) by or on
behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to June 1, 2003, then the premium, as discussed
below, will become immediately due and payable to the extent permitted by law
upon the acceleration of the Notes. The premium payable for purposes of this
paragraph for each of the years beginning on June 1, of the years set forth
below shall be as set forth in the following table expressed as a percentage of
the

                                      A2-7

<PAGE>   110


amount that would otherwise be due but for the provisions of this sentence, plus
accrued interest, if any, to the date of payment:

         13. Trustee Dealings with Company. The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not the Trustee.

         14. No Recourse Against Others. A director, officer, employee,
incorporator, partner, member or stockholder, of the Company or any Subsidiary
of the Company or any Guarantor, as such, shall not have any liability for any
obligations of the Company under the Notes, the Subsidiary Guarantees or the
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Note waives and
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Notes.

         15. Authentication. This Note shall not be valid until authenticated by
the manual signature of a Responsible Officer of the Trustee or an
authenticating agent.

         16. Abbreviations. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN joint tenants with right of survivorship and
not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to
Minors Act).

         17. Additional Rights of Holders of Restricted Global Notes and
Restricted Definitive Notes. In addition to the rights provided to Holders of
Notes under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of June 8, 1998, between the Company and the parties named on
the signature pages thereof (the "Registration Rights Agreement").

         18. CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

         SUPPLEMENTAL INDENTURE (this "Supplemental Indenture"), dated as of
_______________, _____ among GulfMark Offshore, Inc., a Delaware corporation
(the "Company"), [Guarantor] (the "Guarantor"), and State Street Bank and Trust
Company, as trustee under the indenture referred to below (the "Trustee").
Capitalized terms used herein and not defined herein shall have the meaning
ascribed to them in the Indenture (as defined below).

                              W I T N E S S E T H

         WHEREAS, the Company has heretofore executed and delivered to the
Trustee an indenture (the "Indenture"), dated as of June 8, 1998, providing for
the issuance of an aggregate principal amount of $130,000,000 of 8 3/4% Senior
Notes due 2008 (the "Notes");

         WHEREAS, Article 10 of the Indenture provides that under certain
circumstances the Company may or must cause certain of its subsidiaries to
execute and deliver to the Trustee a supplemental indenture pursuant to which
such subsidiaries shall unconditionally guarantee all of the Company's
Obligations under the Notes pursuant to a Subsidiary Guarantee on the terms and
conditions set forth herein; and

         WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

         NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the
Company, the Guarantor and the Trustee mutually covenant and agree for the equal
and ratable benefit of the Holders of the Notes as follows:

         1. Agreement to Guarantee. Subject to Section 10.05 of the Indenture,
each Guarantor hereby, jointly and severally, unconditionally guarantees to each
Holder of a Note authenticated and delivered by the Trustee and to the Trustee
and its successors and assigns, the Notes and the Obligations of the Company
under the Notes or under the Indenture, that: (a) the principal of, premium, if
any, interest and Liquidated Damages, if any, on the Notes will be promptly paid
in full when due, subject to any applicable grace period, whether at maturity,
by acceleration, redemption or otherwise, and interest on overdue principal,
premium, if any, (to the extent permitted by law) interest on any interest, if
any, and Liquidated Damages, if any, on the Notes and all other payment
Obligations of the Company to the Holders or the Trustee under the Indenture or
under the Notes will be promptly paid in full and performed, all in accordance
with the terms thereof; and (b) in case of any extension of time of payment or
renewal of any Notes or any of such other payment Obligations, the same will be
promptly paid in full when due or performed in accordance with the terms of the
extension or renewal, subject to any applicable grace period, whether at stated
maturity, by acceleration, redemption or otherwise. Failing payment when so due
of any amount so 

                                      D-1

<PAGE>   124


guaranteed or any performance so guaranteed for whatever reason, the Guarantors
will be jointly and severally obligated to pay the same immediately.

         The obligations of the Guarantors to the Holders and to the Trustee
pursuant to this Supplemental Indenture and the Indenture are expressly set
forth in Article 10 of the Indenture, and reference is hereby made to such
Indenture for the precise terms of this Subsidiary Guarantee. The terms of
Article 10 of the Indenture are incorporated herein by reference. This
Subsidiary Guarantee is subject to release as and to the extent provided in
Section 10.04 of the Indenture.

         This is a continuing Subsidiary Guarantee and shall remain in full
force and effect and shall be binding upon each Guarantor and its respective
successors and assigns to the extent set forth in the Indenture until full and
final payment of all of the Company's Obligations under the Notes and the
Indenture and shall inure 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 herein conferred
upon that party shall automatically extend to and be vested in such transferee
or assignee, all subject to the terms and conditions hereof. This is a
Subsidiary Guarantee of payment and not a guarantee of collection.

         Each Guarantor hereby waives diligence, presentment, demand of payment,
filing of claims with a court in the event of insolvency or bankruptcy of the
Company, any right to require a proceeding first against the Company, protest,
notice and all demands whatsoever and covenants that this Subsidiary Guarantee
will not be discharged except by complete performance of the Obligations
contained in the Notes and the Indenture.

         This Subsidiary Guarantee shall not be valid or obligatory for any
purpose until the certificate of authentication on the Note upon which this
Subsidiary Guarantee is noted shall have been executed by the Trustee under the
Indenture by the manual signature of one of its authorized officers.

         For purposes hereof, each Guarantor's liability shall be limited to the
lesser of (i) the aggregate amount of the Obligations of the Company under the
Notes and the Indenture and (ii) the amount, if any, which would not have (A)
rendered such Guarantor "insolvent" (as such term is defined in the Bankruptcy
Code and in the Debtor and Creditor Law of the State of New York) or (B) left
such Guarantor with unreasonably small capital at the time its Subsidiary
Guarantee of the Notes was entered into; provided that, it will be a presumption
in any lawsuit or other proceeding in which a Guarantor is a party that the
amount guaranteed pursuant to the Subsidiary Guarantee is the amount set forth
in clause (i) above unless any creditor, or representative of creditors of such
Guarantor, or debtor in possession or trustee in bankruptcy of such Guarantor,
or proves in such a lawsuit that the aggregate liability of the Guarantor is
limited to the amount set forth in clause (ii) above. The Indenture provides
that, in making any determination as to the solvency or sufficiency of capital
of a Guarantor in accordance with the previous sentence, the right of such
Guarantors to contribution from other Guarantors as set forth in the Indentures
and any other rights such Guarantors may have, contractual or otherwise, shall
be taken into account.

<PAGE>   125



         2. No Recourse Against Others. No past, present or future director,
officer, employee, incorporator, partner, member, shareholder or agent of any
Guarantor, as such, shall have any liability for any obligations of the Company
or any Guarantor under the Notes, any Subsidiary Guarantees, the Indenture or
this Supplemental Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder by accepting a Note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes.

         3. New York Law to Govern.  THE INTERNAL LAW OF THE STATE OF NEW YORK 
SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE.

         4. Counterparts. The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

         5. Effect of Headings. The Section headings herein are for convenience
only and shall not affect the construction hereof.

         6. The Trustee. The Trustee shall not be responsible in any manner
whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or for or in respect of the correctness of the recitals of fact
contained herein, all of which recitals are made solely by the New Guarantor.

SECTION 3.                REGISTERED EXCHANGE OFFER

         (a)     Unless the Exchange Offer shall not be permissible under
applicable law or Commission policy (after the procedures set forth in Section
6(a) below have been complied with), the Company shall (i) cause to be filed
with the Commission as soon as practicable after the Closing Date, but in no
event later than 60 days after the Closing Date, the Exchange Offer
Registration Statement under the Securities Act relating to the New Senior
Notes and the Exchange Offer, (ii) use its best efforts to cause such Exchange
Offer Registration Statement to become effective at the earliest possible time,
but in no event later than 150 days after the Closing Date, (iii) in connection
with the foregoing, (A) file all pre-effective amendments to such Exchange
Offer Registration Statement as may be necessary in order to cause such
Exchange Offer Registration Statement to become effective, (B) if applicable,
file a post-effective amendment to such Exchange Offer Registration Statement
pursuant to Rule 430A under the Securities Act and (C) cause all necessary
filings, if any, in connection with the registration and qualification of the
New Senior Notes to be made under the Blue Sky laws of such jurisdictions as
are necessary to permit Consummation of the





                                      -4-
<PAGE>   5
Exchange Offer and (iv) upon the effectiveness of such Exchange Offer
Registration Statement, commence and Consummate the Exchange Offer.  The
Exchange Offer shall be on the appropriate form permitting registration of the
New Senior Notes to be offered in exchange for the Transfer Restricted
Securities and to permit sales of Broker-Dealer Transfer Restricted Securities
by Broker-Dealers as contemplated by Section 3(c) below.

         (b)     The Company shall use its best efforts to cause the Exchange
Offer Registration Statement to be effective continuously for a period of 180
days from the date on which the Exchange Offer Registration Statement is
declared effective and shall keep the Exchange Offer open for a period of not
less than the minimum period required under applicable federal and state
securities laws to Consummate the Exchange Offer; provided, however, that in no
event shall such period be less than twenty (20) Business Days. The Company
shall cause the Exchange Offer to comply with all applicable federal and state
securities laws.  No securities other than the Notes shall be included in the
Exchange Offer Registration Statement.  The Company shall use its best efforts
to cause the Exchange Offer to be Consummated on the earliest practicable date
after the Exchange Offer Registration Statement has become effective, but in no
event later than thirty (30) Business Days thereafter.

         (c)     The Company shall include a "Plan of Distribution" section in
the Prospectus contained in the Exchange Offer Registration Statement and
indicate that any Broker-Dealer who holds Senior Notes that are Transfer
Restricted Securities and that were acquired for the account of such
Broker-Dealer as a result of market-making activities or other trading
activities (other than Transfer Restricted Securities acquired directly from
the Company or one of its Affiliates) may exchange such Senior Notes pursuant
to the Exchange Offer; however, such Broker-Dealer may be deemed to be an
"underwriter" within the meaning of the Securities Act and must, therefore,
deliver a prospectus meeting the requirements of the Securities Act in
connection with its initial sale of the New Senior Notes received by such
Broker-Dealer in the Exchange Offer, which prospectus delivery requirement may
be satisfied by the delivery by such Broker-Dealer of the Prospectus contained
in the Exchange Offer Registration Statement.  Such "Plan of Distribution"
section shall also contain all other information with respect to such resales
of Broker-Dealer Transfer Restricted Securities that the Commission may require
in order to permit such sales pursuant thereto but such "Plan of Distribution"
shall not name any such Broker-Dealer or disclose the amount of Notes held by
any such Broker-Dealer except to the extent required by the Commission as a
result of a change in policy after the date of this Agreement.

         The Company shall use its best efforts to keep the Exchange Offer
Registration Statement continuously effective, supplemented and amended as
required by the provisions of Section 6(c) below to the extent necessary to
ensure that it is available for resales of Broker-Dealer Transfer Restricted
Securities acquired by Restricted Broker-Dealers and to ensure that it
conforms with the requirements of this Agreement, the Securities Act and the
policies, rules and regulations of the Commission as announced from time to
time, for a period of 180 days from the date on which the Exchange Offer
Registration Statement is declared effective.





                                      -5-
<PAGE>   6
         The Company shall provide sufficient copies of the latest version of
such Prospectus to such Restricted Broker-Dealers promptly upon request at any
time during such 180 day period in order to facilitate such sales.

SECTION 4.                SHELF REGISTRATION

         (a)     Shelf Registration.  If (i) the Company is not required to
file an Exchange Offer Registration Statement or to consummate the Exchange
Offer because the Exchange Offer is not permitted by applicable law or
Commission policy (after the procedures set forth in Section 6(a) below have
been complied with) or (ii) if any Holder of Transfer Restricted Securities
shall notify the Company within twenty (20) Business Days of the Consummation
of the Exchange Offer that (A) such Holder is prohibited by applicable law or
Commission policy from participating in the Exchange Offer, or (B) such Holder
may not resell the New Senior Notes acquired by it in the Exchange Offer to the
public without delivering a prospectus and that the Prospectus contained in the
Exchange Offer Registration Statement is not appropriate or available for such
resales by such Holder, or (C) such Holder is a Broker-Dealer and holds Senior
Notes acquired directly from the Company or one of its Affiliates, then the
Company shall:

                 (x)      cause to be filed a shelf registration statement
         pursuant to Rule 415 under the Securities Act, which may be an
         amendment to the Exchange Offer Registration Statement (in either
         event, the "Shelf Registration Statement") on or prior to the earliest
         to occur of (1) the 60th day after the date on which the Company
         receives notice from the Commission or determines that it is not
         required to file the Exchange Offer Registration Statement pursuant to
         clause (i) above, (2) the 60th day after the date on which the Company
         receives notice from a Holder of Transfer Restricted Securities as
         contemplated by clause (ii) above, and (3) the 150th day after the
         Closing Date (such earliest date being the "Shelf Filing Deadline"),
         which Shelf Registration Statement shall provide for resales of all
         Transfer Restricted Securities the Holders of which shall have
         provided the information required pursuant to Section 4(b) hereof; and

                 (y)      use its best efforts to cause such Shelf Registration
         Statement to be declared effective by the Commission on or before the
         60th day after the Shelf Filing Deadline.

         The Company shall use its best efforts to keep such Shelf Registration
Statement continuously effective, supplemented and amended as required by and
subject to the provisions of Sections 6(b) and (c) hereof to the extent
necessary to ensure that it is available for sales of Transfer Restricted
Securities by the Holders thereof entitled to the benefit of this Section 4(a),
and to ensure that it conforms with the requirements of this Agreement, the
Securities Act and the policies, rules and regulations of the Commission as
announced from time to time, for a period of at least two years (as extended
pursuant to Section 6(c)(i)) following the date on which such Shelf
Registration Statement first becomes effective under the Securities Act or such
shorter period ending when all of the Transfer Restricted Securities available
for sale thereunder have been sold pursuant thereto.





                                      -6-
<PAGE>   7
         (b)     Provision by Holders of Certain Information in Connection with
the Shelf Registration Statement.  No Holder of Transfer Restricted Securities
may include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 Business Days after receipt of a request
therefor, such information as the Company may reasonably request for use in
connection with any Shelf Registration Statement or Prospectus or preliminary
Prospectus included therein.  No Holder of Transfer Restricted Securities shall
be entitled to Liquidated Damages pursuant to Section 5 hereof unless and until
such Holder shall have provided all such reasonably requested information.
Each Holder as to which any Shelf Registration Statement is being effected
agrees to furnish promptly to the Company all information required to be
disclosed in order to make the information previously furnished to the Company
by such Holder not materially misleading.

SECTION 5.                LIQUIDATED DAMAGES

         If (i) any of the Registration Statements required by this Agreement
are not filed with the Commission on or prior to the date specified for such
filing in this Agreement, (ii) any of such Registration Statements have not
been declared effective by the Commission on or prior to the date specified for
such effectiveness in this Agreement (the "Effectiveness Target Date"), (iii)
the Exchange Offer has not been Consummated within 30 Business Days after the
Effectiveness Target Date with respect to the Exchange Offer Registration
Statement or (iv) any Registration Statement required by this Agreement is
filed and declared effective but shall thereafter cease to be effective or fail
to be usable for its intended purpose without being succeeded within 30 days by
a post-effective amendment to such Registration Statement, the effectiveness of
another Registration Statement or the use of the Prospectus (as amended or
supplemented) is again permitted that cures such failure (each such event
referred to in clauses (i) through (iv), a "Registration Default"), the Company
hereby agrees to pay Liquidated Damages to each Holder of Transfer Restricted
Securities with respect to the first 90-day period immediately following the
occurrence of such Registration Default, in an amount equal to $0.05 per week
per $1,000 principal amount of Transfer Restricted Securities held by such
Holder for each week or portion thereof that the Registration Default
continues.  The amount of the Liquidated Damages shall increase by an
additional $0.05 per week per $1,000 in principal amount of Transfer Restricted
Securities with respect to each subsequent 90-day period until all Registration
Defaults have been cured, up to a maximum amount of Liquidated Damages of $0.50
per week per $1,000 principal amount of Transfer Restricted Securities.  All
accrued Liquidated Damages shall be paid to the Global Note Holder by the
Company by wire transfer of immediately available funds or by federal funds
check and to Holders of Definitive Notes by wire transfer to the accounts
specified by them or by mailing checks to their registered addresses if no such
accounts have been specified on each Damages Payment Date, as provided in the
Indenture.  Notwithstanding anything to the contrary set forth herein, (1) upon
filing of the Exchange Offer Registration Statement (and/or, if applicable, the
Shelf Registration Statement), in the case of (i) above, (2) upon the
effectiveness of the Exchange Offer Registration Statement (and/or, if
applicable, the Shelf Registration Statement), in the case of (ii) above, (3)
upon Consummation of the Exchange Offer, in the case of (iii) above, or (4)
upon the filing of a post-effective amendment to the Registration Statement or
an additional Registration Statement that causes the Exchange Offer
Registration Statement (and/or, if applicable, the Shelf Registration





                                      -7-
<PAGE>   8
Statement) to again be declared effective or the Prospectus to be made usable
in the case of (iv) above, the Liquidated Damages payable with respect to the
Transfer Restricted Securities as a result of such clause (i), (ii), (iii) or
(iv), as applicable, shall cease.

         All obligations of the Company set forth in the preceding paragraph
that are outstanding with respect to any Transfer Restricted Security at the
time such security ceases to be a Transfer Restricted Security shall survive
until such time as all such obligations with respect to such security shall
have been satisfied in full.

SECTION 6.                REGISTRATION PROCEDURES

         (a)     Exchange Offer Registration Statement.  In connection with the
Exchange Offer, the Company shall comply with all applicable provisions of
Section 6(c) below, shall use its best efforts to effect such exchange to
permit the sale of Broker-Dealer Transfer Restricted Securities being sold in
accordance with the intended method or methods of distribution thereof (which
shall be in a manner consistent with the terms of this Agreement), and shall
comply with all of the following provisions:

                 (i)      If, following the date hereof and prior to the
         Consummation of the Exchange Offer, there has been published a change
         in Commission policy with respect to exchange offers such as the
         Exchange Offer, such that in the reasonable opinion of counsel to the
         Company there is a substantial question as to whether the Exchange
         Offer is permitted by applicable law or Commission policy, the Company
         hereby agrees to seek a no- action letter or other favorable decision
         from the Commission allowing the Company to Consummate an Exchange
         Offer for such Senior Notes.  The Company hereby agrees to pursue the
         issuance of such a decision to the Commission staff level but shall
         not be required to take commercially unreasonable action to effect a
         change of Commission policy.  The Company hereby agrees, however, to
         take all such other actions as are reasonably requested by the
         Commission or otherwise required in connection with the issuance of
         such decision, including without limitation, to (A) participate in
         telephonic conferences with the Commission, (B) deliver to the
         Commission staff an analysis prepared by counsel to the Company
         setting forth the legal bases, if any, upon which such counsel has
         concluded that such an Exchange Offer should be permitted and (C)
         diligently pursue a resolution (which need not be favorable) by the
         Commission staff of such submission.

                 (ii)     As a condition to its participation in the Exchange
         Offer pursuant to the terms of this Agreement, each Holder of Transfer
         Restricted Securities shall furnish, upon the request of the Company,
         prior to the Consummation thereof, a written representation to the
         Company (which may be contained in the letter of transmittal
         contemplated by the Exchange Offer Registration Statement) to the
         effect that (A) it is not an Affiliate of the Company, (B) it is not
         engaged in, and does not intend to engage in, and has no arrangement
         or understanding with any person to participate in, a distribution of
         the New Senior Notes to be issued in the Exchange Offer and (C) it is
         acquiring the New Senior Notes in its ordinary course of business.  In
         addition, all such Holders of Transfer Restricted Securities shall





                                      -8-
<PAGE>   9
         otherwise reasonably cooperate in the Company's preparations for the
         Exchange Offer.  Each Holder hereby acknowledges and agrees that any
         Broker-Dealer and any such Holder using the Exchange Offer to
         participate in a distribution of the securities to be acquired in the
         Exchange Offer (1) could not under Commission policy as in effect on
         the date of this Agreement rely on the position of the Commission
         enunciated in Morgan Stanley and Co., Inc. (available June 5, 1991)
         and Exxon Capital Holdings Corporation (available May 13, 1988), as
         interpreted in the Commission's letter to Sherman & Sterling dated
         July 2, 1993, and similar no-action letters (including any no-action
         letter obtained pursuant to clause (i) above), and (2) must comply
         with the registration and prospectus delivery requirements of the
         Securities Act in connection with a secondary resale transaction and
         that such a secondary resale transaction should be covered by an
         effective registration statement containing the selling security
         holder information required by Item 507 or 508, as applicable, of
         Regulation S-K if the resales are of New Senior Notes obtained by such
         Holder in exchange for Senior Notes acquired by such Holder directly
         from the Company or an Affiliate thereof.

                 (iii)    Prior to effectiveness of the Exchange Offer
         Registration Statement, the Company shall provide a supplemental
         letter to the Commission (A) stating that the Company is registering
         the Exchange Offer in reliance on the position of the Commission
         enunciated in Exxon Capital Holdings Corporation (available May 13,
         1988), Morgan Stanley and Co., Inc. (available June 5, 1991) and, if
         applicable, any no-action letter obtained pursuant to clause (i)
         above, (B) including a representation that the Company has not entered
         into any arrangement or understanding with any Person to distribute
         the New Senior Notes to be received in the Exchange Offer and that, to
         the best of the Company's information and belief, each Holder
         participating in the Exchange Offer is acquiring the New Senior Notes
         in its ordinary course of business and has no arrangement or
         understanding with any Person to participate in the distribution of
         the New Senior Notes received in the Exchange Offer and (C) any other
         undertaking or representation required by the Commission as set forth
         in any no-action letter obtained pursuant to clause (i) above.

         (b)     Shelf Registration Statement.  In connection with the Shelf
Registration Statement, the Company shall comply with all the provisions of
Section 6(c) below and shall use its best efforts to effect such registration
to permit the sale of the Transfer Restricted Securities being sold in
accordance with the intended method or methods of distribution thereof, and
pursuant thereto the Company will as expeditiously as possible, and in any
event within the time periods and otherwise in accordance with the provisions
hereof, prepare and file with the Commission a Registration Statement relating
to the registration on any appropriate form under the Securities Act, which
form shall be available for the sale of the Transfer Restricted Securities in
accordance with the intended method or methods of distribution thereof.

         (c)     General Provisions.  In connection with any Registration
Statement and any Prospectus required by this Agreement to permit the sale or
resale of Transfer Restricted Securities (including, without limitation, any
Exchange Offer Registration Statement and the related Prospectus





                                      -9-
<PAGE>   10
required to permit resales of Transfer Restricted Securities by Restricted
Broker-Dealers), the Company shall:

                 (i)      use its best efforts to keep such Registration
         Statement continuously effective and provide all requisite financial
         statements for the period specified in Section 3 or 4 of this
         Agreement, as applicable; upon the occurrence of any event that would
         cause any such Registration Statement or the Prospectus contained
         therein (A) to contain a material misstatement or omission or (B) not
         to be effective and usable for resale of Transfer Restricted
         Securities during the period required by this Agreement, the Company
         shall file promptly an appropriate amendment to such Registration
         Statement, (1) in the case of clause (A), correcting any such
         misstatement or omission, and (2) in the case of either clause (A) or
         (B), use its best efforts to cause such amendment to be declared
         effective and such Registration Statement and the related Prospectus
         to become usable for their intended purpose(s) as soon as practicable
         thereafter;

                 (ii)     prepare and file with the Commission such amendments
         and post-effective amendments to the Registration Statement as may be
         necessary to keep the Registration Statement effective for the
         applicable period set forth in Section 3 or 4 hereof, as applicable,
         or such shorter period as will terminate when all Transfer Restricted
         Securities covered by such Registration Statement have been sold;
         cause the Prospectus to be supplemented by any required Prospectus
         supplement, and as so supplemented to be filed pursuant to Rule 424
         under the Securities Act, and to comply fully with the applicable
         provisions of Rules 424, 430A and 462, as applicable under the
         Securities Act in a timely manner; and comply with the provisions of
         the Securities Act with respect to the disposition of all securities
         covered by such Registration Statement during the applicable period in
         accordance with the intended method or methods of distribution by the
         sellers thereof set forth in such Registration Statement or supplement
         to the Prospectus;

                 (iii)    advise the underwriter(s), if any, and selling
         Holders promptly and, if requested by such Persons, to confirm such
         advice in writing, (A) when the Prospectus or any Prospectus supplement
         or post-effective amendment thereto has been filed, and, with respect
         to any Registration Statement or any post-effective amendment thereto,
         when the same has become effective, (B) of any request by the
         Commission for amendments to the Registration Statement or amendments
         or supplements to the Prospectus or for additional information relating
         thereto, (C) of the issuance by the Commission of any stop order
         suspending the effectiveness of the Registration Statement under the
         Securities Act or of the suspension by any state securities commission
         of the qualification of the Transfer Restricted Securities for offering
         or sale in any jurisdiction, or the initiation of any proceeding for
         any of the preceding purposes, (D) of the existence of any fact or the
         happening of any event that makes any statement of a material fact made
         in the Registration Statement, the Prospectus, any amendment or
         supplement thereto, or any document incorporated by reference therein
         untrue in any material respect, or that requires the making of any
         additions to or changes in the Registration Statement or the Prospectus
         in order to make the statements therein, in light of the circumstances
         under which they were made, not misleading.  If at any time the





                                      -10-
<PAGE>   11
         Commission shall issue any stop order suspending the effectiveness of
         the Registration Statement, or any state securities commission or
         other regulatory authority shall issue an order suspending the
         qualification or exemption from qualification of the Transfer
         Restricted Securities under state securities or Blue Sky laws, the
         Company shall use its best efforts to obtain the withdrawal or lifting
         of such order at the earliest practicable time;

                 (iv)     upon written request, furnish to the Initial
         Purchasers, and, upon written request, to each of the selling Holders
         and each of the underwriter(s) in connection with such sale, if any,
         before filing with the Commission, copies of any Registration
         Statement or any Prospectus included therein or any amendments or
         supplements to any such Registration Statement or Prospectus, which
         documents will be subject to the review of such Holders and
         underwriter(s) in connection with such sale, if any, for a period of
         at least five Business Days, and the Company will not file any such
         Registration Statement or Prospectus or any amendment or supplement to
         any such Registration Statement or Prospectus to which a selling
         Holder of Transfer Restricted Securities covered by such Registration
         Statement or the underwriter(s) in connection with such sale, if any,
         shall reasonably object within five Business Days after the receipt
         thereof.  A selling Holder or underwriter in connection with such
         sale, if any, shall be deemed to have reasonably objected to such
         filing (A) if such Registration Statement, amendment, Prospectus or
         supplement, as applicable, as proposed to be filed, contains a
         material misstatement or omission or fails to comply with the
         applicable requirements of the Securities Act or (B) if any of the
         information furnished to the Company by such selling Holder or
         underwriter in connection with such sale, if any, and included in such
         Registration statement, amendment, Prospectus or supplement, as
         applicable, as proposed to be filed is incorrect in any respect;

                 (v)      upon written request, promptly prior to the filing of
         any document that is to be incorporated by reference into a
         Registration Statement or Prospectus, provide copies of such document
         to the selling Holders and to the underwriter(s) in connection with
         such sale, if any, make the Company's representatives available for
         discussion of such document and other customary due diligence matters,
         and include such information in such document prior to the filing
         thereof as such selling Holders or underwriters, if any, reasonably
         may request;

                 (vi)     in the case of a shelf registration, make available
         at reasonable times for inspection by the selling Holders, any
         underwriter participating in any disposition pursuant to such
         Registration Statement, and any attorney or accountant retained by
         such selling Holders or any of the underwriter(s), all relevant
         financial and other records, pertinent corporate documents and
         properties of the Company and cause the Company's officers, directors
         and employees to supply all information reasonably requested by any
         such Holder, underwriter, attorney or accountant in connection with
         such Registration Statement or any post-effective amendment thereto
         subsequent to the filing thereof and prior to its effectiveness;
         provided, however, that such persons shall first agree in writing with
         the Company that any information that is reasonably and in good faith
         designated by the Company in writing as confidential at the time of
         delivery of such information shall be kept confidential by such
         persons, unless (i) disclosure of such information is required by
         court





                                      -11-
<PAGE>   12
         or administrative order or is necessary to respond to inquiries of
         regulatory authorities, (ii) disclosure of such information is
         required by law (including any disclosure requirements pursuant to
         Federal securities laws in connection with the filing of the Shelf
         Registration Statement or the use of any Prospectus), (iii) such
         information becomes generally available to the public other than as a
         result of a disclosure or failure to safeguard such information by
         such person or (iv) such information becomes available to such person
         from a source other than the Company and its subsidiaries and such
         source is not bound by a confidentiality agreement; and provided,
         further, that the foregoing inspection and information gathering shall
         be coordinated on behalf of the Initial Purchasers by Lehman Brothers
         Inc., and on behalf of any other persons, by one counsel designated by
         and on behalf of such other persons;

                 (vii)    if requested by any selling Holders or the
         underwriter(s) in connection with such sale, if any, promptly
         incorporate in any Registration Statement or Prospectus, pursuant to a
         supplement or post-effective amendment if necessary, such information
         as such selling Holders and underwriter(s), if any, may reasonably
         request to have included therein, including, without limitation,
         information relating to the "Plan of Distribution" of the Transfer
         Restricted Securities, information with respect to the principal
         amount of Transfer Restricted Securities being sold to such
         underwriter(s), the purchase price being paid therefor and any other
         terms of the offering of the Transfer Restricted Securities to be sold
         in such offering; and make all required filings of such Prospectus
         supplement or post-effective amendment as soon as practicable after
         the Company is notified of the matters to be incorporated in such
         Prospectus supplement or post-effective amendment;

                 (viii)   cause the Transfer Restricted Securities covered by
         the Registration Statement to be rated with the appropriate rating
         agencies, if so requested by the Holders of a majority in aggregate
         principal amount of Notes covered thereby or the underwriter(s) in
         connection with such sale, if any, unless such Transfer Restricted
         Securities are already so rated;

                 (ix)     furnish to each selling Holder and each of the
         underwriter(s) in connection with such sale, if any, without charge,
         at least one copy of the Registration Statement, as first filed with
         the Commission, and of each amendment thereto, including all documents
         incorporated by reference therein and all exhibits (including exhibits
         incorporated therein by reference);

                 (x)      deliver to each selling Holder and each of the
         underwriter(s), if any, without charge, as many copies of the
         Prospectus (including each preliminary prospectus) and any amendment
         or supplement thereto as such Persons reasonably may request; the
         Company hereby consents to the use of the Prospectus and any amendment
         or supplement thereto by each of the selling Holders and each of the
         underwriter(s), if any, in connection with the offering and the sale
         of the Transfer Restricted Securities covered by the Prospectus or any
         amendment or supplement thereto;





                                      -12-
<PAGE>   13
                 (xi)     enter into such agreements (including an underwriting
         agreement), and make such representations and warranties with respect
         to the business of the Company as are customarily addressed in
         representations and warranties made by issuers to underwriters in
         underwritten offerings, and take all such other actions in connection
         therewith in order to expedite or facilitate the disposition of the
         Transfer Restricted Securities pursuant to any Registration Statement
         contemplated by this Agreement, all to such extent as may be
         reasonably requested by the Initial Purchasers or by any Holder of
         Transfer Restricted Securities or underwriter in connection with any
         sale or resale pursuant to any Registration Statement contemplated by
         this Agreement; and whether or not an underwriting agreement is
         entered into and whether or not the registration is an Underwritten
         Registration, the Company shall:

                          (A)     furnish to each Initial Purchaser, each
                 selling Holder and each underwriter, if any, in such substance
                 and scope as they may reasonably request and as are
                 customarily made by issuers to underwriters in primary
                 underwritten offerings, upon the date of the Consummation of
                 the Exchange Offer and, if applicable, the effectiveness of
                 the Shelf Registration Statement:

                          (1)     a certificate, dated the date of Consummation
                 of the Exchange Offer or the date of effectiveness of the
                 Shelf Registration Statement, as the case may be, signed on
                 behalf of the Company by the Chairman of the Board, President
                 or any Vice President and Treasurer or Chief Financial Officer
                 of the Company, confirming, as of the date thereof, the
                 matters set forth in paragraph (g) of Section 7 of the
                 Purchase Agreement and such other matters as such parties may
                 reasonably request;

                          (2)     opinions, dated the date of Consummation of
                 the Exchange Offer or the date of effectiveness of the Shelf
                 Registration Statement, as the case may be, of counsel or
                 counsels for the Company and its Principal Subsidiaries (as
                 defined in the Purchase Agreement), covering the matters set
                 forth in paragraphs (c) and (d) of Section 7 of the Purchase
                 Agreement and such other matter as such parties may reasonably
                 request, and in any event including a statement to the effect
                 that such counsel for the Company has participated in
                 conferences with officers and other representatives of the
                 Company, representatives of the independent public accountants
                 for the Company and representatives of and counsel to the
                 Initial Purchasers at which the contents of such Registration
                 Statement and the related Prospectus were discussed and,
                 although such counsel is not passing upon and does not assume
                 any responsibility for the accuracy, completeness or fairness
                 of the statements contained therein (except as specifically
                 stated in such opinion), on the basis of the foregoing, no
                 facts have come to the attention of such counsel that have
                 caused such counsel to believe that the applicable
                 Registration Statement, at the time such Registration
                 Statement or any post-effective amendment thereto became
                 effective, and, in the case of the Exchange Offer Registration
                 Statement, as of the date of Consummation, contained an untrue
                 statement of a material fact or omitted to state a material
                 fact required to be stated therein or necessary to make the





                                      -13-

                 statements therein, in light of the circumstances under which
                 they were made, not misleading, or that the Prospectus
                 contained in such Registration Statement as of its date and,
                 in the case of the opinion dated the date of Consummation of
                 the Exchange Offer, as of the date of Consummation, contained
                 an untrue statement of a material fact or omitted to state a
                 material fact necessary in order to make the statements
                 therein, in light of the circumstances under which they were
                 made, not misleading (it being understood that such counsel
                 need make no comment as to the financial statements and
                 related statistical or financial information and schedules
                 included in any Registration Statement contemplated by this
                 Agreement or the related Prospectus); and

                          (3)     customary comfort letters, dated as of the
                 date of Consummation of the Exchange Offer or the date of
                 effectiveness of the Shelf Registration Statement, as the case
                 may be, from the Company's independent accountants, in the
                 customary form and covering matters of the type customarily
                 covered in comfort letters by underwriters in connection with
                 Underwritten Offerings, and affirming the matters set forth in
                 the comfort letters delivered pursuant to Section 7(e) and (f)
                 of the Purchase Agreement, without exception;

                          (B)     set forth in full or incorporate by reference
                 in the underwriting agreement, if any, the indemnification
                 provisions and procedures of Section 8 hereof with respect to
                 all parties to be indemnified pursuant to said Section; and

                          (C)     deliver such other documents and certificates
                 as may be reasonably requested by such parties to evidence
                 compliance with clause (A) above and with any customary
                 conditions contained in the underwriting agreement or other
                 agreement entered into by the Company pursuant to this clause
                 (xi), if any.

                 The above shall be done at each closing under such
         underwriting or similar agreement, as and to the extent required
         thereunder, and, if at any time the representations and warranties of
         the Company contemplated in clause (A)(1) above cease to be true and
         correct in any material respect, the Company shall so advise the
         Initial Purchasers and the underwriter(s), if any, each selling Holder
         and each Restricted Broker-Dealer promptly and, if requested by such
         Persons, shall confirm such advice in writing;

                 (xii)    prior to any public offering of Transfer Restricted
         Securities, cooperate with the selling Holders, the underwriter(s), if
         any, and its counsel in connection with the registration and
         qualification of the Transfer Restricted Securities under the
         securities or Blue Sky laws of such jurisdictions as the selling
         Holders or underwriter(s), if any, may request and do any and all
         other acts or things necessary or advisable to enable the disposition
         in such jurisdictions of the Transfer Restricted Securities covered by
         the applicable Registration Statement; provided, however, that the
         Company shall not be required to register or qualify as a foreign
         corporation where it is not now so qualified or to take any action
         that would subject it to the service of process in suits or to
         taxation, other





                                      -14-
<PAGE>   15
         than as to matters and transactions relating to the Registration
         Statement, in any jurisdiction where it is not now so subject;

                 (xiii)   shall issue, upon the request of any Holder of Senior
         Notes covered by any Shelf Registration Statement contemplated by this
         Agreement, New Senior Notes, having an aggregate principal amount
         equal to the aggregate principal amount of the Senior Notes
         surrendered to the Company by such Holder in exchange therefor or
         being sold by such Holder; such New Senior Notes to be registered in
         the name of such Holder or in the name of the purchaser(s) of such
         Notes, as the case may be; in return, the Senior Notes held by such
         Holder shall be surrendered to the Company for cancellation;

                 (xiv)    cooperate with the selling Holders and the
         underwriter(s), if any, to facilitate the timely preparation and
         delivery of certificates representing Transfer Restricted Securities
         to be sold and not bearing any restrictive legends; and enable such
         Transfer Restricted Securities to be in such denominations and
         registered in such names as the Holders or the underwriter(s), if any,
         may request at least two Business Days prior to any sale of Transfer
         Restricted Securities made by such underwriter(s);

                 (xv)     use its best efforts to cause the disposition of the
         Transfer Restricted Securities covered by the Registration Statement
         to be registered with or approved by such other governmental agencies
         or authorities as may be necessary to enable the seller or sellers
         thereof or the underwriter(s), if any, to consummate the disposition
         of such Transfer Restricted Securities, subject to the proviso
         contained in clause (xii) above;

                 (xvi)    subject to Section 6(c)(i), if any fact or event
         contemplated by clause 6(c)(iii)(D) above shall exist or have
         occurred, prepare a supplement or post-effective amendment to the
         Registration Statement or related Prospectus or any document
         incorporated therein by reference or file any other required document
         so that, as thereafter delivered to the purchasers of Transfer
         Restricted Securities, the Prospectus will not contain an 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;

                 (xvii)   provide a CUSIP number for all Transfer Restricted
         Securities not later than the effective date of the Registration
         Statement covering such Transfer Restricted Securities and provide the
         Trustee under the indenture with printed certificates for the Transfer
         Restricted Securities which are in a form eligible for deposit with
         the Depositary Trust Company;

                 (xviii)  cooperate and assist in any filings required to be
         made with the NASD and in the performance of any due diligence
         investigation by any underwriter (including any "qualified independent
         underwriter" that is required to be retained in accordance with the
         rules and regulations of the NASD), and use its best efforts to cause
         such Registration Statement to become effective and approved by such
         governmental agencies or authorities





                                      -15-
<PAGE>   16
         as may be necessary to enable the Holders selling Transfer Restricted
         Securities to consummate the disposition of such Transfer Restricted
         Securities;

                 (xix)    otherwise use its best efforts to comply with all
         applicable rules and regulations of the Commission, and make generally
         available to its security holders, as soon as practicable, a
         consolidated earnings statement meeting the requirements of Rule 158
         (which need not be audited) for the twelve-month period (A) commencing
         at the end of any fiscal quarter in which Transfer Restricted
         Securities are sold to underwriters in a firm or best efforts
         Underwritten Offering or (B) if not sold to underwriters in such an
         offering, beginning with the first month of the Company's first fiscal
         quarter commencing after the effective date of the Registration
         Statement;

                 (xx)     cause the Indenture to be qualified under the TIA not
         later than the effective date of the first Registration Statement
         required by this Agreement, and, in connection therewith, cooperate
         with the Trustee and the Holders of Notes to effect such changes to
         the Indenture as may be required for such Indenture to be so qualified
         in accordance with the terms of the TIA; and execute and use its best
         efforts to cause the Trustee to execute, all documents that may be
         required to effect such changes and all other forms and documents
         required to be filed with the Commission to enable such Indenture to
         be so qualified in a timely manner;

                 (xxi)    cause all Transfer Restricted Securities covered by
         the Registration Statement to be listed on each securities exchange on
         which similar securities issued by the Company are then listed if
         requested by the Holders of a majority in aggregate principal amount
         of Senior Notes or the managing underwriter(s), if any; and

                 (xxii)   provide promptly to each Holder upon request each
         document filed with the Commission pursuant to the requirements of
         Section 13 and Section 15(d) of the Exchange Act.

         (d)     Restrictions on Holders.  (i) Each Holder agrees by
acquisition of a Transfer Restricted Security that, upon receipt of the notice
referred to in Section 6(c)(i) or any notice from the Company of the existence
of any fact of the kind described in Section 6(c)(iii)(D) hereof, such Holder
will forthwith discontinue disposition of Transfer Restricted Securities
pursuant to the applicable Registration Statement until such Holder's receipt
of the copies of the supplemented or amended Prospectus contemplated by Section
6(c)(xvi) hereof, or until it is advised in writing (the "Advice") by the
Company that the use of the Prospectus may be resumed, and has received copies
of any additional or supplemental filings that are incorporated by reference in
the Prospectus.  If so directed by the Company, each Holder will deliver to the
Company (at the Company's expense) all copies, other than permanent file copies
then in such Holder's possession, of the Prospectus covering such Transfer
Restricted Securities that was current at the time of receipt of such notice.
In the event the Company shall give any such notice, the time period regarding
the effectiveness of such Registration Statement set forth in Section 3 or 4
hereof, as applicable, shall be extended by the number of days during the
period from and including the date of the giving of such notice pursuant





                                      -16-
<PAGE>   17
to Section 6(c)(i) or Section 6(c)(iii)(D) hereof to and including the date
when each selling Holder covered by such Registration Statement shall have
received the copies of the supplemented or amended Prospectus contemplated by
Section 6(c)(xvi) hereof or shall have received the Advice.

         (ii)    The Company may require a Holder of Transfer Restricted
Securities to be included in a Registration Statement to furnish to the Company
such information as required by law to be disclosed by such Holder in such
Registration Statement, and the Company may exclude from such Registration
Statement the Transfer Restricted Securities of any Holder who unreasonably
fails to furnish such information within a reasonable time after receiving such
request.

SECTION 7.                REGISTRATION EXPENSES

         All expenses incident to the Company's performance of or compliance
with this Agreement will be borne by the Company, regardless of whether a

SECTION 8.                INDEMNIFICATION

         (a)     The Company, jointly and severally, shall indemnify and hold
harmless each Holder, its directors, officers and employees and each person, if
any, who controls such Holder within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, from and against any and all
losses, claims, damages, liabilities, judgments and actions, joint or several,
or any action in respect thereof (including, but not limited to, any loss,
claim, damage, liability, judgment or action relating to purchases and sales of
Notes), to which that Holder, its directors, officers, employees or controlling
persons may become subject, under the Securities Act or otherwise, insofar as
such loss, claim, damage, liability, judgment or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained in any Registration Statement, Preliminary Prospectus or
Prospectus or in any amendment or supplement thereto or (ii) the omission or
alleged omission to state in any Registration Statement, Preliminary Prospectus
or Prospectus, or in any





                                      -17-
<PAGE>   18
amendment or supplement thereto, any material fact required to be stated
therein or necessary to make the statements therein not misleading, and shall
reimburse such Holder and each such director, officer, employee or controlling
person promptly upon demand for any legal or other expenses reasonably incurred
by such Holder, director, officer, employee or controlling person in connection
with investigating or defending or preparing to defend against any such loss,
claim, damage, liability, judgment or action as such expenses are incurred;
provided, however, that the Company shall not be liable in any such case to the
extent that any such loss, claim, damage, liability, judgment or action arises
out of, or is based upon, any untrue statement or alleged untrue statement or
omission or alleged omission made in any Registration Statement, Preliminary
Prospectus or Prospectus, or in any such amendment or supplement in reliance
upon and in conformity with written information concerning such Holder
furnished to the Company by or on behalf of such Holder specifically for
inclusion therein; provided further, that the indemnity agreement provided in
this Section 8(a) with respect to any Preliminary Prospectus shall not inure to
the benefit of any Holder in any case in which a subsequent purchaser asserts
that its losses, claims, damages, liabilities, or actions was based upon any
untrue statement or alleged untrue statement of material fact or omission or
alleged omission to state therein a material fact in the Preliminary
Prospectus, if a copy of the Prospectus in which such untrue statement or
alleged untrue statement or omission or alleged omission was corrected had not
been sent or given to such subsequent purchaser by such Holder, provided that
the Company delivered such Prospectus to such Holder in requisite quantity and
on a timely basis to permit such delivery or sending.  The foregoing indemnity
agreement is in addition to any liability which the Company may otherwise have
to any Holder or to any director, officer, employee or controlling person of
such Holder.

         (b)     Each Holder, severally and not jointly, shall indemnify and
hold harmless the Company, and its directors, officers and employees and each
person, if any, who controls the Company within the meaning of Section 15 of
the Securities Act or Section 20 of the Exchange Act, from and against any and
all losses, claims, damages, liabilities, judgments or actions, joint or
several, or any action in respect thereof, to which the Company, or any such
director, officer or controlling person may become subject, under the
Securities Act or otherwise, insofar as such loss, claim, damage, liability,
judgment or action arises out of, or is based upon, (i) any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement, Preliminary Prospectus or Prospectus or in any amendment or
supplement thereto or (ii) the omission or alleged omission to state in any
Registration Statement, Preliminary Prospectus or Prospectus, or in any
amendment or supplement thereto, any material fact required to be stated
therein or necessary to make the statements therein not misleading, but in each
case only to the extent that the untrue statement or alleged untrue statement
or omission or alleged omission was made in reliance upon and in conformity
with written information concerning such Holder furnished to the Company by or
on behalf of such Holder specifically for inclusion therein, and shall
reimburse the Company and any such director, officer or controlling person for
any legal or other expenses reasonably incurred by the Company, or any such
director, officer or controlling person in connection with investigating or
defending or preparing to defend against any such loss, claim, damage,
liability, judgment or action as such expenses are incurred.  The foregoing
indemnity agreement is in addition to any liability which any Holder may
otherwise have to the Company, or any such director, officer, employee or
controlling person.





                                      -18-
<PAGE>   19
         (c)     Promptly after receipt by any person in respect of which
indemnity may be sought pursuant to Section 8(a) or 8(b) (the "indemnified
party") of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in respect thereof is to be made against
any person against whom indemnity may be sought pursuant to Section 8(a) or
8(b) (the "indemnifying party"), notify the indemnifying party in writing of
the claim or the commencement of that action; provided, however, that the
failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 8 except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify the indemnifying party shall not relieve it from any
liability which it may have to an indemnified party otherwise than under this
Section 8.  If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party and the payment of all fees and expenses of such counsel shall be the
responsibility of the indemnifying party.  After notice from the indemnifying
party to the indemnified party of its election to assume the defense of such
claim or action, the indemnifying party shall not be liable to the indemnified
party under this Section 8 for any legal or other expenses subsequently
incurred by the indemnified party in connection with the defense thereof other
than reasonable costs of investigation.  In addition, an indemnified party
shall have the right to employ separate counsel in any such action and
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of the indemnified party unless (i) the employment of
such counsel shall have been specifically authorized in writing by the
indemnifying party, (ii) the indemnifying party shall have failed to assume the
defense of such action or employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying
party, and the indemnified party shall have been advised by such counsel that
there may be one or more legal defenses available to it which are different
from or additional to those available to the indemnifying party (in which case
the indemnifying party shall not have the right to assume the defense of such
action on behalf of the indemnified party). In any such case, the indemnifying
party shall not, in connection with any one action or separate but
substantially similar or related actions in the same jurisdiction arising out
of the same general allegations or circumstances, be liable for the fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) of all indemnified parties, and all such fees and expenses shall be
reimbursed as they are incurred.  Such firm shall be designated in writing by
Lehman Brothers Inc. in the case of the parties indemnified pursuant to Section
8(a) and by the Company, in the case of parties indemnified pursuant to Section
8(b).  No indemnifying party shall (i) without the prior written consent of the
indemnified parties (which consent shall not be unreasonably withheld), settle
or compromise or consent to the entry of any judgment with respect to any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding, or (ii) be liable for any settlement of any such action
effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with the consent of the indemnifying party or if
there be a final judgment





                                      -19-
<PAGE>   20
of the plaintiff in any such action, the indemnifying party agrees to indemnify
and hold harmless any indemnified party from and against any loss or liability
by reason of such settlement or judgment.

         (d)     If the indemnification provided for in this Section 8 shall
for any reason be unavailable or insufficient to hold harmless an indemnified
party under Section 8(a) or 8(b) in respect of any loss, claim, damage,
liability, judgment or any action in respect thereof, referred to therein, then
each indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage, liability, judgment or action in respect thereof,
(i) in such proportion as shall be appropriate to reflect the relative benefits
received by the Company, on the one hand, and the Holders, on the other, from
the offering of the Notes 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 Company, on the one hand, and the Holders, on
the other, with respect to the statements or omissions which resulted in such
loss, claim, damage, liability, judgment or action in respect thereof, as well
as any other relevant equitable considerations.  The relative benefits received
by the Company, on the one hand, and the Holders, on the other, with respect to
such offering shall be deemed to be in the same proportion as the total net
proceeds from the offering of the Senior Notes purchased under the Purchase
Agreement (before deducting expenses) received by the Company as set forth in
the table on the cover page of the Offering Memorandum, on the one hand, and
the total net proceeds received by such Holder upon its resale of Notes less
the amount paid by such Holder for such Notes, on the other hand, bear to the
total sum of such amounts.  The relative fault shall be determined by reference
to whether the untrue or alleged untrue statement of a material fact or
omission or alleged omission to state a material fact relates to information
supplied by the Company or such Holder, the intent of the parties and their
relative knowledge, access to information and opportunity to correct or prevent
such statement or omission.  The Company and the Holders agree that it would
not be just and equitable if contributions pursuant to this Section 8 were to
be determined by pro rata allocation or by any other method of allocation which
does not take into account the equitable considerations referred to herein.
The amount paid or payable by an indemnified party as a result of the loss,
claim, damage, liability, judgment or action in respect thereof, referred to
above in this Section 8 shall be deemed to include, for purposes of this
Section 8(d), any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim.  Notwithstanding the provisions of this Section 8(d), no Holder, and
none of its directors, officers, employees or controlling persons, shall be
required to contribute, in the aggregate, any amount in excess of the amount by
which the total net proceeds received by such Holder upon its resale of Notes
exceeds the sum of the amount paid by such Holder for such Notes and the amount
of any damages which such Holder has otherwise paid or become liable to pay by
reason of any 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
Holders' obligations to contribute as provided in this Section 8(d) are several
in proportion to the respective principal amount of Notes held by each of the
Holders hereunder and not joint.

         (e)     The remedies provided for in this Section 8 are not exclusive
and shall not limit any rights or remedies which may otherwise be available to
any indemnified party at law or in equity.

SECTION 9.       RULE 144A

         The Company hereby agrees with each Holder, for so long as any
Transfer Restricted Securities remain outstanding and during any period in
which the Company is subject to Section 13 or 15(d) of the Exchange Act, to
make available to any Holder or beneficial owner of Transfer Restricted
Securities in connection with any sale thereof and any prospective purchaser of
such Transfer Restricted Securities from such Holder or beneficial owner, the
information required by Rule 144A(d)(4) under the Securities Act in order to
permit resales of such Transfer Restricted Securities pursuant to Rule 144A.
Notwithstanding the foregoing, nothing in this Section 9 shall be deemed to
require the Company to register any of its securities pursuant to the Exchange
Act.

SECTION 10.      PARTICIPATION IN UNDERWRITTEN REGISTRATION

         No Holder may participate in any Underwritten Registration hereunder
unless such Holder (a) agrees to sell such Holder's Transfer Restricted
Securities on the basis provided in any underwriting arrangements approved by
the Persons entitled hereunder to approve such arrangements and (b) completes
and executes all reasonable questionnaires, powers of attorney, indemnities,
underwriting agreements, lock-up letters and other documents required under the
terms of such underwriting arrangements.

SECTION 11.      SELECTION OF UNDERWRITERS

         For any Underwritten Offering, the investment banker or investment
bankers and manager or managers that will administer such offering will be
selected by the Holders of a majority in aggregate principal amount of the
Transfer Restricted Securities included in such offering; provided, that such
investment bankers and managers must be reasonably satisfactory to the Company.
Such investment bankers and managers are referred to herein as the
"underwriters."

SECTION 12.      MISCELLANEOUS

         (a)     Remedies.  Each Holder, in addition to being entitled to
exercise all rights provided herein, in the Indenture, the Purchase Agreement
or granted by law, including recovery of liquidated or other damages, will be
entitled to specific performance of its rights under this Agreement.  The
Company agrees that monetary damages (including the Liquidated Damages
contemplated hereby) would not be adequate compensation for any loss incurred
by reason of a breach by them of the provisions of this Agreement and hereby
agree to waive the defense in any action for specific performance that a remedy
at law would be adequate.

         (b)     No Inconsistent Agreements.  The Company will not on or after
the date of this Agreement, enter into any agreement with respect to its
securities that is inconsistent with the rights granted to the Holders in this
Agreement or otherwise conflicts with the provisions hereof. The





                                      -21-
<PAGE>   22
Company is not currently bound by any agreement granting registration rights
with respect to its securities that conflicts with the registration rights set
forth herein.

         (c)     Adjustments Affecting the Notes.  The Company will not take
any action, or permit any change to occur, with respect to the Notes that would
materially and adversely affect the ability of the Holders to Consummate any
Exchange Offer.

         (d)     Amendments and Waivers.  The provisions of this Agreement may
not be amended, modified or supplemented, and waivers or consents to or
departures from the provisions hereof may not be given unless (i) in the case
of Section 5 hereof and this Section 12(d), the Holders of all outstanding
Transfer Restricted Securities and (ii) in the case of all other provisions
hereof, the Company has obtained the written consent of Holders of a majority
of the outstanding principal amount of Transfer Restricted Securities.
Notwithstanding the foregoing, a waiver or consent to departure from the
provisions hereof that relates exclusively to the rights of Holders whose
securities are being tendered pursuant to the Exchange Offer and that does not
affect directly or indirectly the rights of other Holders whose securities are
not being tendered pursuant to such Exchange Offer may be given by the Holders
of a majority of the outstanding principal amount of Transfer Restricted
Securities being tendered or registered.

         (e)     Notices. All notices and other communications provided for or

         Re:   8.75% Senior Notes due 2008

Gentlemen:

         Reference is made to (i) the proposed issuance under the Securities
Act of 1933, as amended  (the "Securities Act") by GulfMark Offshore, Inc., a
Delaware corporation (the "Company"), of up to $130,000,000 aggregate principal
amount of its 8.75% Senior Notes due 2008 (the "Debt Securities") in exchange
for its outstanding 8.75% Senior Notes due 2008 (the "Old Notes") and (ii) the
Company's Registration Statement on Form S-4 (the "Registration Statement")
with respect to such Debt Securities to be filed with the Securities and
Exchange Commission under the Securities Act.  The Debt Securities are to be
issued in accordance with resolutions of the Company's Board of Directors duly
adopted on May 14, 1998 and under and pursuant to the provisions of the
Indenture dated as of June 8, 1998 between the Company and State Street
Bank and Trust Company, as trustee (the "Trustee") (the "Indenture").

         We have examined the Indenture, the global note issued under the
Indenture relating to the Old Notes and such statutes, corporate records and
documents, certificates of corporate and public officials and such other
instruments and documents as we have deemed necessary or appropriate for the
purposes of the opinions expressed herein.

         Based upon the foregoing and subject to the qualifications,
limitations, assumptions and other statements set forth herein, we are of the
opinion that:

         (1)   the Company is a validly existing corporation under the laws of
         the State of Delaware; and

         (2)   the Debt Securities when issued in exchange for the Old Notes
         will be validly issued and will constitute valid and binding
         obligations of the Company, enforceable against the Company in
         accordance with their terms (subject to applicable bankruptcy,
         insolvency, reorganization, fraudulent conveyance, moratorium or other
         similar laws
<PAGE>   2
Board of Directors
July 20, 1998
Page 2


         affecting creditors' rights generally from time to time in effect and
         subject to general principles of equity, regardless of whether such
         enforceability is considered in a proceeding in equity or at law).

         The opinion expressed in paragraph (2) assumes that the Debt
Securities issued under the Indenture have been duly executed, authenticated,
issued and delivered in accordance with the provisions of the Indenture upon
exchange for the Old Notes as provided for therein.

         Except as otherwise stated below, the opinions expressed herein are
based upon, and limited to, the laws of the State of Texas, the State of New
York and the United States and the Delaware General Corporation Law, and to
case decisions reported as of this date under such laws, and to facts known to
us on this date, and we do not undertake to provide any opinion as to any
matter or to advise any person with respect to any events or changes occurring
subsequent to the date of this letter.

         The opinions expressed in this letter are provided as legal opinions
only and not as any guaranties or warranties of the matters discussed herein,
and such opinions are strictly limited to the matters stated herein, and no
other opinions may be implied. This opinion letter is intended solely for your
benefit.  Without our prior written consent, the opinions expressed herein may
not be published or relied upon by you other than in connection with the
Registration Statement or the transactions contemplated therein, or published
or relied upon by any other person in connection with any matter or in any
manner whatsoever.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to this firm under the heading
"Experts" in the Prospectus constituting part of the Registration Statement.

                                        Very truly yours,

                                        /s/ GRIGGS & HARRISON, P.C.

      If the undersigned is not a broker-dealer, the undersigned represents that
it is not engaged in, and does not intend to engage in, a distribution of
Exchange Notes. If the undersigned is a broker-dealer that will receive Exchange
Notes for its own account in exchange for Old Notes that were acquired as a
result of market-making activities or other trading activities, it acknowledges
that it will deliver a prospectus in connection with any resale of such Exchange
Notes; however, by so acknowledging and by delivering a prospectus, the
undersigned will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

                     NOTE: SIGNATURES MUST BE PROVIDED BELOW
                 PLEASE READ ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

      Subject to the terms and conditions of the Exchange Offer, the undersigned
hereby tenders to GulfMark Offshore, Inc. (the "Company") for exchange the
principal amount of Old Notes indicated above.

      Subject to and effective upon the acceptance for exchange of the principal
amount of Old Notes tendered hereby in accordance with this Letter of
Transmittal, the undersigned sells, assigns and transfers to, or upon the order
of, the Company all right, title and interest in and to the Old Notes tendered
hereby. The undersigned hereby irrevocably constitutes and appoints the Exchange
Agent as its agent and attorney-in-fact (with full knowledge that the Exchange
Agent also acts as the agent of the Company and as Trustee and Registrar under
the Indenture for the Old Notes and the Exchange Notes) with respect to the
tendered Old Notes with full power of substitution (such power of attorney being
deemed an irrevocable power coupled with an interest), subject only to the right
of withdrawal described in the Prospectus, to (i) deliver certificates for such
Old Notes to the Company or transfer ownership of such Old Notes on the account
books maintained by DTC, together, in either such case, with all accompanying
evidences of transfer and authenticity to, or upon the order of, the Company and
(ii) present such Old Notes for transfer on the books of the Company and receive
all benefits and otherwise exercise all rights of beneficial ownership of such
Old Notes, all in accordance with the terms of the Exchange Offer.

      The undersigned acknowledges that the Exchange Offer is being made in
reliance upon interpretative advice given by the staff of the Securities and
Exchange Commission to third parties in connection with transactions similar to
the Exchange Offer, so that the Exchange Notes issued pursuant to the Exchange
Offer in exchange for the Old Notes may be offered for resale, resold and
otherwise transferred by Holders thereof (other than a broker-dealer who
purchased


                                      - 5 -

<PAGE>   6



such Old Notes directly from the Company for resale pursuant to Rule 144A or any
other available exemption under the Securities Act or a person that is an
"affiliate" of the Company 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 Exchange Notes are 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 Exchange Notes.

      The undersigned agrees that acceptance of any tendered Old Notes by the
Company and the issuance of Exchange Notes in exchange therefor shall constitute
performance in full by the Company of its obligations under the Registration
Rights Agreement, (as defined in the Prospectus) and that, upon the issuance of
the Exchange Notes, the Company will have no further obligations or liabilities
thereunder (except in certain limited circumstances).

      The undersigned represents and warrants that (i) the Exchange Notes
acquired pursuant to the Exchange Offer are being acquired in the ordinary
course of business of the person receiving Exchange Notes (which shall be the
undersigned unless otherwise indicated in the box entitled "Special Delivery
Instructions" above) (the "Recipient"), (ii) neither the undersigned nor the
Recipient (if different) is engaged in, intends to engage in or has any
arrangement or understanding with any person to participate in the distribution
of such Exchange Notes and (iii) neither the undersigned nor the Recipient (if
different) is an "affiliate" of the Company as defined in Rule 405 under the
Securities Act. If the undersigned is not a broker-dealer, the undersigned
further represents that it is not engaged in, and does not intend to engage in,
a distribution of the Exchange Notes. If the undersigned is a broker-dealer, the
undersigned further (x) represents that it acquired Old Notes for the
undersigned's own account as a result of market making activities or other
trading activities, (y) represents that it has not entered into any arrangement
or understanding with the Company or any "affiliate" of the Company (within the
meaning of Rule 405 under the Securities Act) to distribute the Exchange Notes
to be received in the Exchange Offer and (z) acknowledges that it will deliver a
prospectus meeting the requirements of the Securities Act (for which purposes
delivery of the Prospectus, as the same may be hereafter supplemented or
amended, shall be sufficient) in connection with any resale of Exchange Notes
received in the Exchange Offer. Such a broker-dealer will not be deemed, solely
by reason of such acknowledgment and prospectus delivery, to admit that it is an
"underwriter" within the meaning of the Securities Act.

      The undersigned understands and agrees that the Company reserves the right
not to accept tendered Old Notes from any tendering Holder if the Company
determines, in its sole and absolute discretion, that such acceptance could
result in a violation of applicable securities laws.

      The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, exchange, assign and transfer the Old Notes
tendered hereby and to acquire Exchange Notes issuable upon the exchange of such
tendered Old Notes, and that, when the same are accepted for exchange, the
Company will acquire good and unencumbered title thereto, free and clear of all
liens, restrictions, charges and encumbrances and not subject to any adverse
claim. The undersigned also warrants that it will, upon request, execute and
deliver any additional documents deemed to be necessary or desirable by the
Exchange Agent or the Company in order to complete the exchange, assignment and
transfer of tendered Old Notes or transfer of ownership of such Old Notes on the
account books maintained by a book-entry transfer facility.

      The undersigned understands and acknowledges that the Company reserves the
right in its sole discretion to purchase or make offers for any Old Notes that
remain outstanding subsequent to the Expiration Date or, as set forth in the
Prospectus under the caption "The Exchange Offer -- Procedures for Tendering,"
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.

      The undersigned understands that the Company may accept the undersigned's
tender by delivering notice of acceptance, as provided below, to the Exchange
Agent, at which time the undersigned's right to withdraw such tender will
terminate. For purposes of the Exchange Offer, the Company shall be deemed to
have accepted validly tendered Old Notes when, as and if the Company has given
oral (which shall be confirmed in writing) or written notice thereof to the
Exchange Agent.

      The undersigned understands that the first interest payment following the
Expiration Date will include unpaid interest on the Old Notes accrued through
the date of issuance of the Exchange Notes.

      The undersigned understands that tenders of Old Notes pursuant to the
procedures described under the caption "The Exchange Offer -- Procedures for
Tendering" in the Prospectus and in the instructions hereto will constitute a
binding agreement between the undersigned and the Company upon the terms and
subject to the conditions of the Exchange Offer.

      The undersigned acknowledges that the Exchange Offer is subject to the
more detailed terms set forth in the Prospectus and, in case of any conflict
between the terms of the Prospectus and this Letter of Transmittal, the
Prospectus shall prevail.

      If any tendered Old Notes are not accepted for exchange pursuant to the
Exchange Offer for any reason, certificates for any such unaccepted Old Notes
will be returned (except as noted below with respect to tenders through DTC) at
the Company's cost and expense, to the undersigned at the address shown below or
at a different address as may be indicated herein under "Special Delivery
Instructions" as promptly as practicable after the Expiration Date.

      All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned, and every obligation of the undersigned under this Letter of
Transmittal shall be binding upon the undersigned's heirs, personal
representatives, successors and assigns. This tender may be withdrawn only in
accordance with the procedures set forth in this Letter of Transmittal.

      By acceptance of the Exchange Offer, each broker-dealer that receives
Exchange Notes pursuant to the Exchange Offer hereby acknowledges and agrees
that upon the receipt of notice by the Company of the happening of any event
which makes any statement in the Prospectus untrue in any material respect or
which requires the making of any changes in the Prospectus in order to make the
statements therein not misleading (which notice the Company agrees to deliver
promptly to such broker-dealer), such broker-dealer will suspend use of the
Prospectus until the Company has amended or supplemented the Prospectus to
correct such misstatement or omission and has furnished copies of the amended or
supplemented prospectus to such broker-dealer.

      Unless otherwise indicated under "Special Registration Instructions,"
please issue the certificates representing the Exchange Notes issued in exchange
for the Old Notes accepted for exchange and return any certificates for Old
Notes not tendered or not exchanged, in the name(s) of the undersigned (or, in
either such event in the case of Old Notes tendered by DTC, by credit to the
account at DTC). Similarly, unless otherwise indicated under "Special Delivery
Instructions," please send the certificates representing the Exchange Notes
issued in exchange for the Old Notes accepted for exchange and any certificates
for Old Notes not tendered or not exchanged (and accompanying documents, as
appropriate) to the undersigned at the address shown below the undersign's
signature(s), unless, in either event, tender is being made through DTC. In the
event that both "Special Registration Instructions" and "Special Delivery
Instructions" are completed, please issue the certificates representing the
Exchange Notes issued in exchange for the Old Notes accepted for exchange in the
name(s) of, and return any certificates for Old Notes not tendered or not
exchanged to, the person(s) so indicated. The undersigned understands that the
Company has no obligations pursuant to the "Special Registration Instructions"
or "Special Delivery Instructions" to transfer any Old Notes from the name of
the registered Holder(s) thereof if the Company does not accept for exchange any
of the Old Notes so tendered.

      Holders who wish to tender the Old Notes and (i) whose Old Notes are not
immediately available or (ii) who cannot delivery their Old Notes, this Letter
of Transmittal or any other documents required hereby to the Exchange Agent
prior to the Expiration Date, may tender their Old Notes according to the
guaranteed delivery procedures set forth in the Prospectus under the caption
"The Exchange Offer -- Guaranteed Delivery Procedures."

this letter of Transmittal or facsimile hereof and any other documents required
by this Letter of Transmittal must be received by the Exchange Agent at its
address set forth herein prior to 5:00 p.m., New York City time, on the
Expiration Date.

         The method of delivery of the tendered Old Notes, this Letter of
Transmittal and all other required documents to the Exchange Agent is at the
election and risk of the Holder and the delivery will be deemed made only when
actually received by the Exchange Agent. If Old Notes are sent by mail,
certified or registered mail with return receipt requested, properly insured, is
recommended. In all cases, sufficient time should be allowed to ensure timely
delivery. No Letter of Transmittal or Old Notes should be sent to the Company.

         The Exchange Agent will make a request to establish an account with
respect to the Old Notes at the DTC for purposes of the Exchange Offer promptly
after the date of the Prospectus, and any financial institution that is a
participant in the DTC may make book-entry delivery of Old Notes by causing the
DTC to transfer such Old Notes into the Exchange Agent's account at the DTC in
accordance with the DTC's procedures for transfer. However, although delivery of
Old Notes may be effected through book-entry transfer at the DTC, the Letter of
Transmittal, with any required signature guarantees or an Agent's Message (as
defined below) in connection with a book-entry transfer and any other required
documents, must, in any case, be transmitted to and received by the Exchange
Agent at the address specified on the cover page of the Letter of Transmittal on
or prior to the Expiration Date or the guaranteed delivery procedures described
below must be complied with.

         A Holder may tender Old Notes that are held through the DTC by
transmitting its acceptance through the DTC's Automatic Tender Offer Program,
for which the transaction will be eligible, and the DTC will then edit and
verify the acceptance and send an Agent's Message to the Exchange Agent for its
acceptance. The term "Agent's Message" means a message transmitted by the DTC
to, and received by, the Exchange Agent and forming part of the Book-Entry
Confirmation, which states that the DTC has received an express acknowledgment
from each participant in the DTC tendering the Old Notes and that such
participant has received the Letter of Transmittal and agrees to be bound by the
terms of the Letter of Transmittal and the Company may enforce such agreement
against such participant.

         Holders who wish to tender their Old Notes and (i) whose Old Notes are
not immediately available, or (ii) who cannot deliver their Old Notes, this
Letter of Transmittal or any other documents required hereby to the Exchange
Agent prior to the Expiration Date or comply with book-entry transfer procedures
on a timely basis must tender their Old Notes according to the guaranteed
delivery procedures set forth in the Prospectus. See "Exchange Offer --
Guaranteed Delivery Procedures." Pursuant to such procedure: (i) such tender
must be made by or through an Eligible Institution; (ii) prior to the Expiration
Date, the Exchange Agent must have received from the Eligible Institution a
properly completed and duly executed Notice of Guaranteed Delivery (by facsimile
transmission, overnight courier, mail or hand delivery) setting forth the name
and address of the Holder of the Old Notes, the certificate number or numbers of
such Old Notes and the principal amount of Old Notes tendered, stating that the
tender is being made thereby and guaranteeing that, within three New York Stock
Exchange trading days after the Expiration Date, this Letter of Transmittal (or
facsimile hereof) together with the certificate(s) representing the Old Notes
and any other required documents will be deposited by the Eligible Institution
with the Exchange Agent; and (iii) such properly completed and executed Letter
of Transmittal (or facsimile hereof), as well as all other documents required by
this Letter of Transmittal and the certificate(s) representing all tendered Old
Notes in proper form for transfer (or a confirmation of book-entry transfer of
such Old Notes into the Exchange Agent's account at DTC), must be received by
the Exchange Agent within three New York Stock Exchange trading days after the
Expiration Date, all in the manner provided in the Prospectus under the caption
"The Exchange Offer -- Any Holder who wishes to tender his Old Notes pursuant to
the guaranteed delivery procedures described above must ensure that the Exchange
Agent receives the Notice of Guaranteed Delivery prior to 5:00 p.m., New York
City time, on the Expiration Date. Upon request to the Exchange Agent, a Notice
of Guaranteed Delivery will be sent to Holders who wish to tender their Old
Notes according to the guaranteed delivery procedures set forth above.

         All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Old Notes, and withdrawal of tendered Old Notes
will be determined by the Company in its sole discretion, which determination
will be final and binding. All tendering Holders, by execution of this Letter of
Transmittal (or facsimile thereof), shall waive any right to receive notice of
the acceptance of the Old Notes for exchange. 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 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) shall 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. Neither the
Company, the Exchange Agent nor any other person shall be under any duty to give
notification of defects or irregularities with respect to tenders of Old Notes,
nor shall any of them 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 to the Company's satisfaction or waived. Any Old

<PAGE>   11



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 shall be
returned by the Exchange Agent to the tendering Holders pursuant to the
Company's determination, unless otherwise provided in this Letter of Transmittal
as soon as practicable following the Expiration Date. The Exchange Agent has no
fiduciary duties to the Holders with respect to the Exchange Offer and is acting
solely on the basis of directions of the Company.

         3.    Inadequate Space. If the space provided is inadequate, the
certificate numbers and/or the number of Old Notes should be listed on a
separate signed schedule and attached hereto.

         4.    Tender by Holder. Only a Holder of Old Notes may tender such Old
Notes in the Exchange Offer. Any beneficial owner of Old Notes who is not the
registered Holder and who wishes to tender should arrange with such registered
Holder to execute and deliver this Letter of Transmittal on such beneficial
owner's behalf or must, prior to completing and executing this Letter of
Transmittal and delivering his Old Notes, either make appropriate arrangements
to register ownership of the Old Notes in such beneficial owner's name or obtain
a properly completed bond power from the registered Holder or properly endorsed
certificates representing such Old Notes.

         5.    Partial Tenders; Withdrawals. Tenders of Old Notes will be
accepted only in integral multiples of $1,000. If less than the entire principal
amount of any Old Notes is tendered, the tendering Holder should fill in the
principal amount tendered in the third column of the box entitled "Description
of 8 3/4% Senior Notes due 2008" above. The entire principal amount of any Old
Notes delivered to the Exchange Agent will be deemed to have been tendered
unless otherwise indicated. If the entire principal amount of all Old Notes is
not tendered, then Old Notes for the principal amount of Old Notes not tendered
and a certificate or certificates representing Exchange Notes issued in exchange
for any Old Notes accepted will be sent to the Holder at his or her registered
address, unless a different address is provided in the "Special Delivery
Instructions" box above on this Letter of Transmittal or unless tender is made
through DTC, promptly after the Old Notes are accepted for exchange.

         Except as otherwise provided herein, tenders of Old Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the business
day prior to the Expiration Date. To withdraw a tender of Old Notes in the
Exchange Offer, a written or facsimile transmission notice of withdrawal must be
received by the Exchange Agent at its address set forth herein prior to 5:00
p.m., New York City time, on the business day prior to 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, or, in the case of Old Notes transferred by book-entry
transfer, the name and number of the account at DTC to be credited), (iii) be
signed by the Depositor 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, with respect to the Old Notes, 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
purposes of the Exchange Offer and no Exchange Notes will be issued with respect
thereto unless the Old Notes so withdrawn are validly retendered. Any Old Notes
which have been tendered but which are not accepted for exchange by the Company
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 described in the Prospectus under "The Exchange Offer -- Procedures
for Tendering" at any time prior to the Expiration Date.

         6.    Signatures on the Letter of Transmittal; Bond Powers and
Endorsements. If this Letter of Transmittal (or facsimile hereof) is signed by
the registered Holder(s) of the Old Notes tendered hereby, the signature must
correspond with the name(s) as written on the face of the Old Note without
alteration, enlargement or any change whatsoever.



                                     - 11 -

<PAGE>   12



         If any of the Old Notes tendered hereby are owned of record by two or
more joint owners, all such owners must
sign this Letter of Transmittal.

         If a number of Old Notes registered in different names are tendered, it
will be necessary to complete, sign and submit as many copies of this Letter of
Transmittal as there are different registrations of Old Notes.

         If this Letter of Transmittal (or facsimile hereof) is signed by the
registered Holder or Holders (which term, for the purposes described herein,
shall include a book-entry transfer facility whose name appears on a security
listing as the owner of the Old Notes) of Old Notes tendered and the certificate
or certificates for Exchange Notes issued in exchange therefor is to be issued
(or any untendered principal amount of Old Notes to be reissued) to the
registered Holder, then such Holder need not and should not endorse any tendered
Old Notes, nor provide a separate bond power. In any other case, such Holder
must either properly endorse the Old Notes tendered or transmit a properly
completed separate bond power with this Letter of Transmittal with the
signatures on the endorsement or bond power guaranteed by an Eligible
Institution.

         If this Letter of Transmittal (or facsimile hereof) is signed by a
person other than the registered Holder or Holders of any Old Notes listed, such
Old Notes must be endorsed or accompanied by appropriate bond powers in each
case signed as the name of the registered Holder or Holders appears on the Old
Notes.

         If this Letter of Transmittal (or facsimile hereof) or any Old Notes or
bond powers are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, or 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, evidence satisfactory to the Company of their
authority so to act must be submitted with this Letter of Transmittal.

         Endorsements on Old Notes or signatures on bond powers required by this
Instruction 6 must be guaranteed by an Eligible Institution.

         7.    Special Registration and Delivery Instructions. Tendering Holders
should indicate, in the applicable box or boxes, the name and address to which
Exchange Notes or substitute Old Notes for principal amounts not tendered or not
accepted for exchange are to be issued or sent, if different from the name and
address of the person signing this Letter of Transmittal. In the case of
issuance in a different name, the taxpayer identification or social security
number of the person named must also be indicated.

         8.    Backup Federal Income Tax Withholding and Substitute Form W-9.
Under the federal income tax laws, payments that may be made by the Company on
account of Exchange Notes issued pursuant to the Exchange Offer may be subject
to backup withholding at the rate of 31%. In order to avoid such backup
withholding, each tendering Holder should complete and sign the Substitute Form
W-9 included in this Letter of Transmittal and either (a) provide the correct
taxpayer identification number ("TIN") and certify, under penalties of perjury,
that the TIN provided is correct and that (i) the Holder has not been notified
by the Internal Revenue Service (the "IRS") that the Holder is subject to backup
withholding as a result of failure to report all interest or dividends or (ii)
the IRS has notified the Holder that the Holder is no longer subject to backup
withholding; or (b) provide an adequate basis for exemption. If the tendering
Holder has not been issued a TIN and has applied for one, or intends to apply
for one in the near future, such Holder should write "Applied For" in the space
provided for the TIN in Part I of the Substitute Form W-9, sign and date the
Substitute Form W-9 and sign the Certificate of Payee Awaiting Taxpayer
Identification Number. If "Applied For" is written in Part 1, the Company (or
the Paying Agent under the Indenture governing the Exchange Notes) shall retain
31% of payments made to the tendering Holder during the sixty-day period
following the date of the Substitute Form W-9. If the Holder furnishes the
Exchange Agent or the Company with its TIN within sixty days after the date of
the Substitute Form W-9, the Company (or the Paying Agent) shall remit such
amounts retained during the sixty-day period to the Holder and no further
amounts shall be retained or withheld from payments made to the Holder
thereafter. If, however, the Holder has not provided the Exchange Agent or the
Company with its TIN within such sixty-day period, the Company shall remit such
previously retained amounts to the IRS as backup withholding. In general, if a
Holder is an individual, the TIN is the Social Security number of said
individual. If the Exchange Agent or the Company are not provided with the
correct TIN, the Holder may be subject to a $50 penalty


                                     - 12 -
<PAGE>   13


imposed by the Internal Revenue Service. Certain Holders (including, among
others, all corporations and certain foreign individuals) are not subject to
these backup withholding and reporting requirements. In order for a foreign
individual to qualify as an exempt recipient, such Holder must submit a
statement (generally, IRS Form W-8), signed under penalties of perjury,
attesting to that individual's exempt status. Such statements can be obtained
from the Exchange Agent. For further information concerning backup withholding
and instructions for completing the Substitute Form W-9 (including how to obtain
a taxpayer identification number if you do not have one and how to complete the
Substitute For W-9 if Old Notes are registered in more than one name), consult
the enclosed "Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9."

         Failure to complete the Substitute Form W-9 will not, by itself, cause
Old Notes to be deemed invalidly tendered, but may require the Company (or the
Paying Agent) to withhold 31% of the amount of any payments made on account of
the Exchange Notes. Backup withholding is not an additional income tax. Rather,
the federal income tax liability of a person subject to backup withholding will
be reduced by the amount of tax withheld. If withholding results in an
overpayment of taxes, a refund may be obtained from the IRS.

         9.    Transfer Taxes. The Company will pay all transfer taxes, if any,
applicable to the exchange of Old Notes pursuant to the Exchange Offer. If,
however, certificates representing Exchange Notes or Old Notes for principal
amounts not tendered or accepted for exchange are to be delivered to, or are to
be registered in the name of, any person other than the registered Holder of the
Old Notes tendered hereby, or if tendered Old Notes are registered in the name
of a person other than the person signing this Letter of Transmittal, or if a
transfer tax is imposed for any reason other than the exchange of Old Notes
pursuant to the Exchange Offer, then the amount of any such transfer taxes
(whether imposed on the registered Holder or on any other persons) will be
payable by the tendering Holder. If satisfactory evidence of payment of such
taxes or exemption therefrom is not submitted with this Letter of Transmittal,
the amount of such transfer taxes will be billed directly to such tendering
Holder. See the Prospectus under "The Exchange Offer -- Solicitation of
Tenders; Fees and Expenses."

         Except as provided in this Instruction 9, it will not be necessary for
transfer tax stamps to be affixed to the Old Notes listed in this Letter of
Transmittal.

         10.   Waiver of Conditions. The Company reserves the right, in its sole
discretion, to amend, waive or modify specified conditions in the Exchange Offer
in the case of any Old Notes tendered.

         11.   Mutilated, Lost, Stolen or Destroyed Old Notes. Any tendering
Holder whose Old Notes have been mutilated, lost, stolen or destroyed should
contact the Exchange Agent at the address indicated herein for further
instructions.

         12.   Requests for Assistance or Additional Copies. Requests for
assistance and requests for additional copies of the Prospectus or this Letter
of Transmittal may be directed to the Exchange Agent at the address specified in
the Prospectus or on the first page hereof. Holders may also contact their 
broker, dealer, commercial bank, trust company or other nominee for assistance 
concerning the Exchange Offer.

                            IMPORTANT TAX INFORMATION

         Under federal income tax laws, a Holder whose tendered Old Notes are
accepted for payment is required to provide the Exchange Agent (as payer) with
such Holder's correct TIN on Substitute Form W-9 below or otherwise establish a
basis for exemption from backup withholding. If such Holder is an individual,
the TIN is his or her social security number. If the Exchange Agent is not
provided with the correct TIN, a $50 penalty may be imposed by the Internal
Revenue Service, and payments made pursuant to the Exchange Offer may be subject
to backup withholding.

         Certain Holders (including, among others, all corporations and certain
foreign persons) are not subject to these backup withholding and reporting
requirements. Exempt Holders should indicate their exempt status on Substitute
Form W-9. A foreign person may qualify as an exempt recipient by submitting to
the Exchange Agent a properly completed Internal Revenue Service Form W-8,
signed under penalties of perjury, attesting to that Holder's exempt status. A
Form W-8 can be obtained from the Exchange Agent. See the enclosed "Guidelines
for Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional instructions.

         If backup withholding applies, the Exchange Agent is required to
withhold 31% of any payments made to the Holder or other payee. Backup
withholding is not an additional federal income tax. Rather, the federal income
tax liability of persons subject to backup withholding will be reduced by the
amount of tax withheld. If withholding results in an overpayment of taxes, a
refund may be obtained from the Internal Revenue Service.

PURPOSE OF SUBSTITUTE FORM W-9

         To prevent backup withholding on payments made with respect to the
Exchange Offer, the Holder is required to provide the Exchange Agent with
either: (i) the Holder's correct TIN by completing the form below, certifying
that the TIN provided on Substitute Form W-9 is correct (or that such Holder is
awaiting a TIN) and that (A) the Holder has not been notified by the Internal
Revenue Service that the Holder is subject to backup withholding as a result of
failure to report all interest or dividends of (B) the Internal Revenue Service
has notified the Holder that the Holder is no longer subject to backup
withholding or (ii) an adequate basis for exemption.

WHAT NUMBER TO GIVE THE EXCHANGE AGENT

         The Holder is required to give the Exchange Agent the TIN (e.g., social
security number or employer identification number) of the registered Holder of
the Old Notes. If the Old Notes are held in more than one name or are not held
in the name of the actual owner, consult the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional guidance on which number to report.

         CERTIFICATION OF PAYEE AWAITING TAXPAYER INDEMNIFICATION NUMBER

         I certify, under penalties of perjury, that a Taxpayer Identification
Number has not been issued to me, and that I mailed or delivered an application
to receive a Taxpayer Identification Number to the appropriate Internal Revenue
Service Center or Social Security Administration Office (or I intend to mail or
deliver an application in the near future). I understand that if I do not
provide a Taxpayer Identification Number to the payer, 31% of all payments made
to me on account of the Exchange Notes shall be retained until I provide a
Taxpayer Identification Number to the payer and that, if I do not provide my
Taxpayer Identification Number within sixty days, such retained amounts shall be
remitted to the Internal Revenue Service as backup withholding and 31% of all
reportable payments made to me thereafter will be withheld and remitted to the
Internal Revenue Service until I provide a Taxpayer Identification Number.

2008 (the "Old Notes"), upon the terms and subject to the conditions set forth
in the accompanying Prospectus, dated July ____, 1998 (the "Prospectus"), and
related Letter of Transmittal (which together with the Prospectus constitute the

         Based on an interpretation by the staff of the Securities and Exchange
Commission, Exchange Notes issued pursuant to the Exchange Offer in exchange for
Old Notes may be offered for resale, resold and otherwise transferred by holders
thereof (other than any such holder which is an "affiliate" of the Company
within the meaning of Rule 405 under the Securities Act or a "broker" or
"dealer" registered under the Securities Exchange Act of 1934, as amended)
without compliance with the registration and prospectus delivery provisions of
the Securities Act, provided that such Exchange Notes are 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 Exchange Notes. See
the discussion in the Prospectus under "The Exchange Offer--General."

         The Exchange Offer is not conditioned on any minimum principal amount
of Old Notes being tendered.

         Notwithstanding any other term of the Exchange Offer, the Company will
not be required to accept for exchange, or exchange Exchange Notes for, any Old
Notes not theretofore accepted for exchange and may terminate or amend the
Exchange Offer before the acceptance of such Old Notes, if the conditions
described in the Prospectus under "The Exchange Offer--Conditions to the
Exchange Offer" exist.

         The Company reserves the right not to accept tendered Old Notes from
any tendering holder if the Company determines, in its sole and absolute
discretion, that such acceptance could result in a violation of applicable
securities laws.

To Our Clients:

         Enclosed for your consideration are the Prospectus, dated July ___,
1998 (the "Prospectus") and the related Letter of Transmittal (which together
with the Prospectus constitute the "Exchange Offer") in connection with the
offer by GulfMark Offshore, Inc., a Delaware corporation (the "Company"), to
exchange its outstanding 8 3/4% Senior Notes due 2008 (the "Exchange Notes") for
any and all of the outstanding 8 3/4% Senior Notes due 2008 of the Company (the
"Old Notes"), upon the terms and subject to the conditions set forth in the
Exchange Offer.

         We are the registered holders of Old Notes held for your account. An
exchange of the Old Notes can be made only by us as the registered holders and
pursuant to your instructions. The Letter of Transmittal is furnished to you for
your information only and cannot be used by you to exchange the Old Notes held
by us for your account. The Exchange Offer provides a procedure for holders to
tender by means of guaranteed delivery.

         We request information as to whether you wish us to exchange any or all
of the Old Notes held by us for your account upon the terms and subject to the
conditions of the Exchange Offer.

         Your attention is directed to the following:

         1.    The Exchange Notes will be exchanged for the Old Notes at the
rate of $1,000 principal amount of Exchange Notes for each $1,000 principal
amount of Old Notes. The Exchange Notes will bear interest (as do the Old Notes)
at a rate equal to 8 3/4% per annum, payable semi-annually on June 1 and
December 1 of each year, commencing December 1, 1998 to holders of record on the
immediately preceding May 15 and November 15 respectively. Holders of Exchange
Notes of record on November 15, 1998, will receive on December 1, 1998, an
interest payment in an amount equal to (x) the accrued interest on such Exchange
Notes from the date of issuance thereof to December 1, 1998, plus (y) the
accrued interest on the previously held Old Notes from the date of issuance of
such Old Notes (June 8, 1998) to the date of exchange thereof. Interest will not
be paid on Old Notes that are accepted for exchange. The Notes mature on June 1,
2008. The form and terms of the Exchange Notes are identical in all material
respects to the form and terms of the Old Notes, except that (i) the offering of
the Exchange Notes has been registered under the Securities Act of 1933, as
amended (the "Securities Act"), (ii) the Exchange Notes will not be subject to
transfer restrictions and (iii) the Exchange Notes will not be entitled to
registration or other rights under the Registration Rights Agreement (as defined
in the Prospectus) including payment of liquidated damages upon failure of the
Company to consummate the Exchange Offer or the occurrence of certain other
events.

         2.    Based on existing interpretations by the staff of the Securities
and Exchange Commission, Exchange Notes issued pursuant to the Exchange Offer in
exchange for Old Notes may be offered for resale, resold and otherwise
transferred by holders thereof (other than any such holder which is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act or a "broker" or "dealer" registered under the Securities Exchange Act of
1934, as amended) without compliance with the registration and prospectus
delivery provisions of the Securities Act, provided that such Exchange Notes are
acquired in the ordinary course of such holders' business and such holders have
no arrangement or understanding with any person to participate in the
distribution of such Exchange Notes. See the discussion in the Prospectus under
"The Exchange Offer--General."
<PAGE>   20

         3.    The Exchange Offer is not conditioned on any minimum principal
amount of Old Notes being tendered.

         4.    Notwithstanding any other term of the Exchange Offer, the Company
will not be required to accept for exchange, or exchange Exchange Notes for, any
Old Notes not theretofore accepted for exchange, and may terminate or amend the
Exchange Offer as provided herein before the acceptance of such Old Notes, if
any of the conditions described in the Prospectus under "The Exchange
Offer--Conditions to the Exchange Offer" exist.

         5.    The Exchange Offer will expire at 5:00 p.m., New York City time,
on August ____, 1998, unless extended as provided in the Prospectus and the
Letter of Transmittal (the "Expiration Date"). Tendered Old Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the business
day before the Expiration Date.

         6.    Any transfer taxes applicable to the exchange of the Old Notes
pursuant to the Offer will be paid by the Company, except as otherwise provided
in the Prospectus under "The Exchange Offer--Solicitation of Tenders; Fees and
Expenses" and in Instruction 9 of the Letter of Transmittal.

         If you wish to have us tender any or all of your Old Notes, please so
instruct us by completing, detaching and returning to us the instruction form
attached hereto. An envelope to return your instructions is enclosed. If you
authorize a tender of your Old Notes, the entire principal amount of Old Notes
held for your account will be tendered unless otherwise specified on the
instruction form. Your instructions should be forwarded to us in ample time to
permit us to submit a tender on your behalf by the Expiration Date.

         The Exchange Offer is not being made to, nor will tenders be accepted
from or on behalf of, holders of the Old Notes in any jurisdiction in which the
making of the Exchange Offer or acceptance thereof would not be in compliance
with the laws of such jurisdiction or would otherwise not be in compliance with
any provision of any applicable securities law.
