the option of the Issuer, on any Interest Payment Date (as defined) following
the delivery of the first Vessel, to the extent cash available for distribution
to Holders of Second Priority Exchange Notes on such date is insufficient to pay
all accrued and unpaid interest on the Second Priority Exchange Notes due on
such date, the Issuer may pay such interest by issuing additional Second
Priority Notes having an aggregate principal amount equal to the amount of such
deficiency.

         The Issuer may not issue more than $20.9 million aggregate principal
amount of such additional Second Priority Notes. The First Exchange Priority
Notes are not redeemable at the option of the Issuer prior to June 30, 2002,
except that (i) until June 30, 2000, the Issuer may redeem, at its option, in
the aggregate up to 35% of the aggregate principal amount of each series of
Notes, on a PRO RATA basis, at the redemption prices set forth herein with the
proceeds of one or more Public Equity Offerings (as defined) if at least $100.0
million aggregate principal amount of the First Exchange Priority Notes and
untendered First Priority Existing Notes and $45.0 million aggregate principal
amount of the Second Priority Exchange Notes and untendered Second Priority
Exchange Notes remain outstanding after any such redemption and (ii) the Issuer
may redeem each series of Notes at any time if the Issuer or any Owner (as
defined) becomes subject to withholding taxes on any amounts payable under the
Notes or on any Guarantee (as defined) as a result of certain changes in law in
respect of withholding taxes. On and after June 30, 2002, the First Priority
Exchange Notes are redeemable at the option of the Issuer, in whole or in part,
at the redemption prices set forth herein. Commencing on June 30, 2001, and
semi-annually thereafter, the Issuer will be required, to the extent of any
Available Cash (as defined) on each such date, to make an offer to each Holder
(as defined) of First Priority Exchange Notes to purchase such Holder's First
Priority Exchange Notes (or at such Holder's option, any part thereof) at a
purchase price equal to 102% of the principal amount thereof plus accrued and
unpaid interest to the date of purchase.

each an Isle of Man private limited company and a wholly owned subsidiary of the
Issuer (each, an "Owner" and, collectively, the "Owners" and, together with
Navigator Holdings PLC and the Issuer, the "Company"). See "PROSPECTUS SUMMARY--
SECURITY." See "DESCRIPTION OF THE EXCHANGE NOTES--TRUST ACCOUNTS" and
"--APPLICATION OF PROCEEDS."

         The Issuer will accept for exchange any and all Existing Notes validly
tendered and not withdrawn prior to 5:00 p.m., New York City time, on
______________, 1997, unless extended (as so extended, the "Expiration Date").
Tenders of Existing Notes may be withdrawn at any time prior to 5:00 p.m., New
York City time, on the Expiration Date. The Exchange Offer is subject to certain
customary conditions.  See "THE EXCHANGE OFFER."

         Based on interpretations by the staff of the Securities and Exchange
Commission (the "Commission") set forth in no-action letters issued to third
parties, the Company believes that Exchange Notes issued pursuant to the
Exchange Offer may be offered for resale, resold or otherwise transferred by a
Holder who is not 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 the Holder
is acquiring the Exchange Notes in its ordinary course of business 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. However, the
staff of the Commission has not considered the Exchange Offer in the context of
a no-action letter addressed to the Company, and there can be no assurance that
the staff of the Commission would make a similar determination with respect to
the Exchange Offer as it has in its prior interpretations. Persons who desire to
exchange Existing Notes in the Exchange Offer must represent to the Company,
among other things, that such conditions have been met.

         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 accompanying this Prospectus 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 Existing Notes where such Existing Notes were acquired by such broker-dealer
as a result of market-making activities or other trading activities. The Company
has agreed that, starting on the Expiration Date and ending on the close of
business on the first anniversary of the Expiration Date, it will make this
Prospectus, as supplemented or amended, available to any broker-dealer for use
in connection with any resale. See "PLAN OF DISTRIBUTION."

                       ENFORCEABILITY OF CIVIL LIABILITIES

         The Issuer and each of the Owners is organized under the laws of the
Isle of Man. A substantial portion of the assets of their respective assets is
or may be located outside the United States. As a result, it may be difficult
for investors to enforce outside the United States judgments against the Issuer
or the Owners obtained in the United States in any actions, including actions
predicated on the civil liability provisions of the federal securities laws of
the United States. Certain directors of the Issuer and the Owners are residents
of jurisdictions other than the United States, and all or a significant portion
of the assets of such persons are or may be located outside the United States.
As a result, it may be difficult for investors to effect service of process
within the United States upon such persons or to enforce against them in United
States courts judgments predicated upon the civil liability provisions of the
federal securities laws of the United States. There is currently no treaty
between the United States and the Isle of Man providing for reciprocal
recognition and enforcement of judgments in civil and commercial matters, and
therefore a final judgment for the payment of money rendered by any federal or
state court in the United States based on civil liability, whether or not
predicated solely upon the federal securities laws, would not be automatically
enforceable in the Isle of Man. Each of the Issuer and the Owners has
irrevocably submitted to the non-exclusive jurisdiction of the federal and state
courts in The City of New York for the purpose of any legal suit, action or
proceeding against it in connection with the offering and sale of the Notes.

         The foregoing discussion is based on the advice of Cains, counsel to
the Company, with respect to matters of Isle of Man law.

                              AVAILABLE INFORMATION

                  The Issuer and the Owners are not currently subject to the
periodic reporting and other informational requirements of the Exchange Act.
Each of the Issuer and the Owners has agreed that, whether or not it is required
to do so by the rules and regulations of the Commission, for so long as any of
the Notes remain outstanding, it will furnish to the Trustees (as defined) and
the Holders of the Notes and file with the Commission, or cause to be so filed
as part of the financial statements of the Company (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 Issuer and the Owners were required

DEFINITIONS OF CERTAIN TERMS USED IN THIS PROSPECTUS.

                                   THE COMPANY

         The Company was formed in 1997 for the purpose of building and
operating a fleet of five state-of-the-art 22,000 cubic meter ("cbm")
semi-refrigerated ethylene-capable gas carriers. The Vessels are designed to
transport the entire range of petrochemical gases, including ethylene,
propylene, vinyl chloride monomer ("VCM"), butadiene and crude C4, as well as
liquified petroleum gases ("LPG"), such as ethane, propane and butane. There are
no ethylene-capable semi-refrigerated gas carriers currently operating or under
construction that will be larger than the Vessels. Each Vessel will have four
separate gas cargo tanks, segregated pumping and piping systems and a separate
deck tank, allowing each Vessel to carry up to three separate cargoes
simultaneously.

         Upon their construction, the Vessels will be among the most versatile
gas carriers in the world in terms of cargo options, ease and speed of loading
and discharging cargoes and adaptability for route scheduling. The foregoing
capabilities will permit the Company to minimize operating costs, reduce voyage
times and maximize Vessel utilization. In addition, the Vessels' larger cargo
capacities, compared to the existing ethylene-capable fleet, offer significant
economies of scale, especially for long-haul transport.

         Navigator Gas Transport issued the Existing Notes, the proceeds of
which have and will be loaned to the Owners to fund the construction of their
Vessels, to pay certain expenses and to pay interest on the Notes during the
scheduled construction period of the Vessels. The Vessels will be constructed by
Jiangnan Shipyard ("Jiangnan") and China Shipbuilding Trading Company, Limited
("CST" and, together with Jiangnan, the "Builders") under the technical
supervision of MARTIME-Gesellschaft fur maritime Dienstleistung mbH "Martime" or
the "Technical Advisor"), an affiliate of Gesellschaft fur Konzeption, Beratung,
Vermittlung und Betreuung privater Investitionen mbH ("GEBAG"), in coordination
with Germanischer Lloyd, an independent vessel classification society (the
"Classification Society").

                   THE PETROCHEMICAL MARKET AND SEABORNE TRADE

         The Company believes that the gas freight market represents one of the
most attractive sectors of the shipping industry in terms of its robust
underlying demand growth dynamics and the outlook for limited expansion in
freight capacity. The Vessels will address increasing customer demand for larger
semi-refrigerated gas carriers designed for long-haul trade in petrochemical
gases. The transportation of petrochemical gases is a rapidly-growing market
with a few large participants. The Company intends to become a leading
participant in this market to service the major producers, refiners, traders and
end-users of petrochemical gases. The Company believes that the following
factors create an attractive opportunity for the construction of the Vessels:

         DEMAND FOR GAS TRANSPORTATION. Demand for the seaborne transportation
of ethylene and other petrochemical gases is driven by growth in gross domestic
product and increased standards of living, particularly in net importing regions
such as the Far East, the Mediterranean and the Indian subcontinent.
Petrochemical gases are used in the production of a vast array of chemicals and
finished products, including plastics and synthetic-based materials. New
production technologies are


<PAGE>

allowing plastic and synthetic-based materials to displace metal, cotton, wood
and other materials in an increasing number of end-products. From 1990 to 1996,
global production of major petrochemical gases increased at a compound annual
growth rate of 4.4%. Import growth in Asia of such major petrochemical gases,
over this same period, increased at a compound annual growth rate of 9.4%.
By-products of petroleum refining, ethylene and other petrochemical gases are
primarily produced in major petroleum-processing regions such as the Middle
East, North America, South America and northwestern Europe. The Company believes
that large and growing net exports from these regions to meet the increasing
global demand for petrochemical gases will continue to generate strong growth in
seaborne trade.

         Cross-trading of petrochemical gases between and among producing and
consuming regions to satisfy supply and demand imbalances will also contribute
to growth in demand for deep sea transport. Cross-trading will be influenced by
price imbalances among regions, mismatches in domestic production capabilities
and consumption requirements, and planned and unplanned outages in production
and manufacturing facilities. The Company believes that worldwide growth in
consumption of end-products produced from petrochemicals will result in growth
in cross-trading of petrochemical gases.

         Furthermore, because many gas carriers trade in both petrochemical
gases and alternate cargoes such as LPG and ammonia, growth in the demand for
seaborne transport of LPG and ammonia will tend to reduce the vessel capacity
available to transport petrochemical gases and may positively affect freight
rates for ethylene and other petrochemical gases.

         CONSTRUCTION OF MAJOR PETROCHEMICAL PRODUCTION AND TERMINAL FACILITIES.
As a result of the expansion of existing facilities and the construction of
major new petrochemical production facilities and associated large-scale
terminals, the amount of petrochemical gases transported by sea has increased.
New petrochemical production capacity of 46.8 million tonnes is expected to be
on line by the beginning of the next decade, representing a 28.7% increase over
global capacity at the end of 1996. Examples of such large-scale modern
facilities include a 3.3 million tonne petrochemical plant, which includes a 1.4
million tonne ethylene plant, currently under construction in Taiwan; an 830,000
tonne ethylene plant planned to be built by a Mobil Corporation venture in
Venezuela; and Exxon Chemical Company's planned 800,000 tonne ethylene and
400,000 tonne propylene facility in Singapore. These expanded and new facilities
are typically incorporating large-scale storage terminals which include multiple
tanks capable of handling many different petrochemical products. The Company
believes that the Vessels' large capacity as well as their ability to carry a
full range of petrochemical gas cargoes will make them attractive to major
participants in the petrochemical industry.

         AN ATTRACTIVE MARKET FOR SEABORNE TRADE OF ETHYLENE. The Company
believes that the market for seaborne transportation of ethylene, the key
building block for plastics and a feedstock to other petrochemicals, is
particularly attractive. World ethylene production capacity has doubled over the
past 15 years to a total capacity of approximately 81 million tonnes in 1996,
with production capacity increasing by 5.5% during 1996. This trend is expected
to continue with additional production capacity of approximately 27 million
tonnes expected by the beginning of the next decade. Due to its low temperature
requirement (-104(degree)C), ethylene is the most demanding gas cargo to
transport and is carried primarily by smaller, more specialized vessels. As a
result, ethylene has typically commanded higher charter rates than other
petrochemical gases. There are no ethylene-capable vessels which are currently
operating or under construction that are over 12,500 cbm. In addition, the
Vessels will be capable of carrying ethane, a feedstock for ethylene which also
has a low


                                       -2-
<PAGE>

temperature requirement (-82(degree)C). The Company believes the market for the
transportation of ethane will become a premium-rate market.

         BARRIERS TO ENTRY. Over the past several years, the gas carrier
industry has experienced an increased emphasis on higher quality vessels and
enhanced operating efficiencies as both customers and regulatory authorities
have increasingly focused on safety issues and environmental
protection.
As the industry faces more stringent operating standards, including
International Safety Management ("ISM") code certification, Chemical
Distribution Industry ("CDI") certification and inspection certification by
major customers, the Company believes that the existing fleet will find it
increasingly difficult to compete without major capital investment for upgrades.
Whereas in the oil carrier industry the entrance of new owners is commonplace,
few vessel owners have the resources and the access to commercial and technical
expertise necessary to build and operate an efficient-size fleet of
petrochemical gas carriers and to attract major customers. In addition, few
shipyards have the capabilities and experience required to build gas carriers,
which incorporate sophisticated gas plant systems. Existing shipyard capacity is
also currently constrained by the strong demand for less technically-demanding
vessels such as oil tankers, drybulk vessels and container carriers. Given these
entry barriers and the unique capabilities of the Vessels, the Company believes
that it will have a competitive advantage over other industry participants. See
"Business--The Vessels."

         STRONG SECONDHAND VESSEL VALUES. Producers, refiners, traders and
end-users of petrochemical gases do not typically own or control their own
vessels. Instead, vessels are owned by a limited number of experienced
operators, each with a relatively large fleet. This market structure, combined
with the complexity of building and operating vessels capable of carrying
petrochemical gases, has resulted in these vessels maintaining strong secondhand
values over time. For example, a 15,000 cbm semi-refrigerated gas carrier built
in 1990 was sold in the secondary market in early 1997 at a price equal to 93%
of its delivered cost, reflecting the high expected return and the high
replacement cost of these vessels.

BUSINESS STRATEGY

         The Company's business strategy is to take advantage of the strong
demand for seaborne transportation of petrochemical gases and LPG resulting from
the worldwide expansion in the production, use and trade of petroleum
by-products. The Company's fleet is expected to supply transportation services
to existing customers of certain entities that will become shareholders of
Holdings (the "Shareholders") through the Equity Financing (as defined),
including major oil, chemical and trading companies. The key elements of this
strategy include:

         INTEGRATED CHARTERING STRATEGY. Charterers of gas carriers such as the
Vessels rely on short and long-term contracts of affreightment and, to a lesser
extent, time and spot charters, allowing them to respond quickly and efficiently
to the changing trading patterns of the petrochemical gas market. The Company
intends to take advantage of these market dynamics by building a portfolio of
contracts of affreightment with major customers. Such contracts are expected to
be from three to five years in length and would provide the Vessels with a high
level of continuous employment. The Company also intends to use the spot market
and, to a lesser extent, time charters of the Vessels to achieve maximum
capacity utilization and minimize ballast trips and idle time. This strategy
will be implemented by MarLink Schiffahrtskontor GmbH ("MarLink"), an affiliate
of GEBAB, the commercial manager of the Vessels. MarLink is a leading commercial
manager of vessels in the petrochemical gas market.


                                      -3-
<PAGE>

         The Manager is currently negotiating two contracts of affreightment for
the employment of the Vessels in the ethylene and propylene trades. One contract
would guarantee a minimum of 10 voyages and a maximum of 20 voyages per annum
for a full cargo of propylene from the Americas to the Mediterranean region. The
second contract would ensure a minimum of 18 voyages and a maximum of 28 voyages
per annum for a full cargo of ethylene from various loading ports to the
Mediterranean region. Each contract would be for a five-year period with freight
rates for each voyage to be based on then-prevailing market rates. If
consummated, these contracts could provide a base-load of continuous employment
for the Vessels during the terms thereof. However, there can be no assurance
that these contracts will be consummated.

         MAXIMIZE ETHYLENE BUSINESS. Historically, ethylene has generally
achieved an approximate 10-15% premium over charter rates for other
petrochemical gas cargoes. As ethylene frequently trades along the same routes
as other petrochemical gases, the Vessels' multiple tank configuration should
enable the Company to maximize the proportion of its freight mix accounted for
by ethylene, without sacrificing cargo capacity utilization or route efficiency.
Based on historical trends, as well as the increasing size of production
facilities, the Company also believes that the average size of ethylene freights
will increase, thereby enhancing the competitiveness of the Vessels.

         BUILD VERSATILE VESSELS WITH MULTI-CARGO CAPABILITY. The Vessels will
be among the most versatile petrochemical gas carriers in the world given their
ability to carry the full range of petrochemical gases and transport up to three
segregated cargoes simultaneously. The Company believes that these larger,
multiple-tank vessels will provide a competitive advantage over other operators
in the petrochemical gas freight market. In addition, the Vessels will offer
improved operating efficiencies due to their higher speed and shorter loading
and discharge times as compared to many less sophisticated vessels. The Company
has chosen the Builders because of their previous experience in the building of
gas carriers with Tractebel Gas Engineering GmbH ("TGE"), a leading engineering
firm in the production of gas plants. See "Business--The Vessels" and "--The
Builders and TGE."

         MAXIMIZE VESSEL UTILIZATION. The Company believes that its fleet size
of five Vessels, each with four tanks and the ability to carry up to three fully
segregated cargoes, will allow it to adopt triangular trade patterns which
minimize ballast trips. In addition, the Vessels' ability to carry up to three
cargoes simultaneously will give the Company the potential to service up to 15
charterers at any one time. The Company believes that the size of the Vessels
will also be attractive to charterers with substantial long-haul transport
requirements. The Company's fleet size and configuration should provide the
operational flexibility necessary to meet the logistical demands of managing
complex trading patterns.

                                   THE VESSELS

         The Vessels will be state-of-the-art gas carriers. The Company believes
that the size and configuration of the Vessels, as well as the features
incorporated therein, will make them more attractive to charterers than other
vessels. As a result, the Company expects the Vessels to realize
higher-than-average levels of utilization in the transport of high value
petrochemical gas cargoes as compared to other gas carriers, significantly
enhancing the earnings potential of each Vessel.

         The Vessels will be semi-refrigerated, combining refrigeration and
pressurization to maintain their cargoes in a liquified state. This will allow
the Vessels to load products at varying temperatures from different terminals.
In addition to pre-cooled cargoes, the Vessels will have the


                                       -4-
<PAGE>

ability to load cargoes that cannot maintain their required liquid temperatures
prior to loading, due to distances traveled by pipeline from production
facilities to vessels, by accepting these cargoes under pressure and cooling
them on board the Vessels during the voyage. The load time of these cargoes is
thereby reduced since the cargoes do not need to be cooled prior to loading.
Unlike semi-refrigerated vessels, fully-refrigerated vessels are only able to
load cargoes in a cooled state, requiring those vessels to cool products prior
to loading. This requirement slows product loading and limits the number of
terminals which can be efficiently serviced by such vessels.

         The nitrogen generator and deck tank on the Vessels will allow them to
prepare their tanks for the next cargo while en route to the next load port.
This will result in time savings of as much as three days on some voyages, as
tank preparation would otherwise have to be carried out in port. These features
provide a significant benefit to charterers and terminal operators by improving
their terminal utilization. The 22,000 cbm carrying capacity of the Vessels will
also be beneficial to charterers and terminal operators by reducing the number
of loading and discharging operations, the duration of such operations and the
associated costs.

         The contractual delivery dates (each, a "Contractual Delivery Date") of
the Vessels will be staggered as follows (assuming the absence of delays caused

                                      Second Priority Notes under the
                                      Registration Rights Agreement.

                                      Based on interpretations by the
                                      Commission's staff set forth in no-action
                                      letters issued to third parties unrelated
                                      to the Company, the Company believes that
                                      the First Priority Exchange Notes and the
                                      Second Priority Exchange Notes
                                      (collectively, the "Exchange Notes")

                                      or Existing Second Priority Notes
                                      (collectively, the "Existing Notes") may
                                      be offered for resale, resold or otherwise
                                      transferred by any Holder (other than any
                                      such Holder or such other person (i) that
                                      is an "affiliate" of the Company within
                                      the meaning of Rule 405 under the
                                      Securities Act or (ii) that is a
                                      broker-dealer who acquired such Existing
                                      Notes directly from the Issuer (or any
                                      affiliate thereof)), without compliance
                                      with the registration and prospectus
                                      delivery provisions of the Securities Act,
                                      PROVIDED that (i) the Exchange Notes are
                                      acquired in the ordinary course of
                                      business of the Holder and (ii) the Holder
                                      is not engaged in and does not intend to
                                      engage in a distribution of the Exchange
                                      Notes and has no arrangement or
                                      understanding with any person to
                                      participate in the distribution of the
                                      Exchange Notes. The Commission, however,
                                      has not considered the Exchange Offer in
                                      the context of a no-action letter, and
                                      there can be no assurance that the staff
                                      of the Commission would make a similar
                                      determination with respect to the Exchange
                                      Offer as in such other circumstances. See

                                      THE EXCHANGE OFFER." Each broker-dealer
                                      that receives Exchange Notes for its own
                                      account in exchange for Existing Notes,
                                      where those Existing Notes were acquired
                                      by the broker-dealer as a result of its
                                      market-making activities or other trading
                                      activities, must acknowledge that it will

                                      any resale of those Exchange Notes. See

Registration Rights Agreement........ The Existing Notes were sold by the Issuer
                                      on August 7, 1997 in a private placement.

Effect of Not Tendering.............  Existing Notes that are not tendered or

                                      further obligation to provide for the

                                      things, limit the ability of the Issuer
                                      and the Owners to (i) incur any additional
                                      Indebtedness, (ii) pay dividends or make
                                      certain other Restricted Payments, (iii)

                                      consolidations, (x) conduct certain
                                      business activities, (xi) impair the
                                      security interests in the Collateral and

                                      Agreements. In addition, the Indentures
                                      limit the business activities of Holdings,
                                      including its ability to incur
                                      Indebtedness. See "Description of the

LIMITED PURPOSE NATURE OF THE ISSUER, THE OWNERS AND HOLDINGS; LACK OF OPERATING
HISTORY OF OWNERS

         The Exchange Notes and the untendered Existing Notes, if any, represent
obligations of the Issuer guaranteed by the Owners. The activity of the Issuer
is limited to issuing the Notes, entering into the Letter of Credit
Reimbursement Agreement, owning the Owners and lending the net proceeds of the
Offerings and making other advances to the Owners. See "Description of the
Exchange Notes--Certain Covenants." The Issuer has no source of payment for the
Exchange Notes and the untendered Existing Notes, if any, other than payments it
receives from the Owners under the Intercompany Notes and through dividends. The
Issuer has no operating history or financial statements for any period prior to
the Offerings.

         The Exchange Notes and the untendered Existing Notes, if any, are
guaranteed by the Owners, which guarantees are secured by certain of the
Collateral. See "Description of the Exchange Notes--Guarantees" and
"--Security." The activity of the Owners is limited to guaranteeing the Exchange
Notes and the untendered Existing Notes, if any, guaranteeing the Issuer's
obligations under the Letter of Credit Reimbursement Agreement, owning,
operating and maintaining the Vessels and fulfilling its obligations under the
Indentures, the Security Agreements and the Letter of Credit Reimbursement
Agreement. See "Description of the Exchange Notes--Certain Covenants." On and
after the Delivery Date of a Vessel, the Owners' sources of funds will be
earnings on the Vessels, earnings on Temporary Cash Investments (as defined) and
the proceeds from any loss with respect to the Vessels. None of the Owners has
any operating history or financial statements for any period prior to the
Offerings.


                                      -20-

         The Exchange Notes and the untendered Existing Notes, if any, are not
obligations of, and are not guaranteed by, any of the Shareholders. See
"Description of the Exchange Notes--Guarantees" and "--Security." Holdings has
no operating history or financial statements for any period prior to the
Offerings. The activity of Holdings is limited to owning the Issuer and
making the Holdings Pledge.

RISKINESS OF REVENUES RELATING TO THE VESSELS

         Historically, the revenues generated by gas carriers have been
cyclical, with attendant volatility in their profitability resulting from
changes in supply and demand. The transportation rates received by the Company
will be primarily dependent upon the supply of vessels capable of transporting
cargoes such as those the Company intends to transport and the level of demand
for the seaborne trade of such cargoes. These variables will be influenced by
global and regional economic conditions, increases and decreases in the
industrial production of and demand for the cargoes to be transported by such
vessels and the products that are made therefrom, political changes and armed
conflicts, developments in international trade, changes in seaborne and other
transportation patterns and geopolitical events which interrupt production,
trade routes or consumption. Because many of the factors influencing the supply
of, demand and trade patterns for tonnage and cargo are unforeseeable and beyond
the control of the Company, the Company cannot predict the nature, direction,
timing or degree of changes in the revenues generated by the Vessels. In
addition to transportation rates, the revenues generated by the Vessels will
depend on the level of utilization of the Vessels and the mix of cargoes
transported thereon.


NON-PERFORMANCE BY BUILDERS AND PROVIDERS OF THE BUILDING CONTRACT GUARANTEES
AND THE PERFORMANCE BONDS; UNCERTAINTY OF OUTCOME OF ARBITRATION

         Under each Building Contract, the Owner may rescind such Building
Contract upon the occurrence of an event of default by the Builders, including
the failure by the Builders to (i) make timely payment of liquidated damages to
such Owner for delays in the delivery of the Vessel beyond 210 days after the
Contractual Delivery Date, (ii) deliver the Vessel by March 31, 2001 or (iii)
construct the Vessel in conformity with certain specifications. In addition,
each Building Contract provides for the automatic termination of such Building
Contract if, prior to the Delivery Date, (A)(i) a Vessel is seized by the
Chinese government, (ii) the Builders fail to obtain the necessary licenses,
permits and other authorizations from the Chinese government for the
construction, delivery and export from China of such Vessel or (iii) a total
loss occurs with respect to a Vessel and (B) the Builders do not elect to
continue performing under such Building Contract. In addition, if any Building
Contract is rescinded by the Owner or automatically terminated, each other Owner
that has not accepted delivery of its Vessel will be deemed to have also
rescinded its Building Contract through the cross-default provisions. See
"Business--Building Contracts."

         In the event that an Owner rescinds a Building Contract pursuant to its
terms or a Building Contract is automatically terminated, the Owner is entitled
to receive the Refund Amount under such Building Contract from the Builders. If
the Builders default on their obligations to pay the Owner the Refund Amount,
the Building Contract Guarantor and the Performance Bond Guarantors (each, as
defined) have severally and not jointly guaranteed the payment of amounts which
in the aggregate will equal the Refund Amount payable by the Builders. The
Refund Amount together with the amounts held in the Pre-Funding Account and the
Capitalized Interest Account will be used to pay the Allocated Principal Amount
of the Notes, subject to the mandatory redemption plus any accrued


                                      -21-
<PAGE>

and unpaid interest thereon, and certain fees and expenses incurred in
connection with such redemption. To the extent the Builders fail to pay the
Owners the Refund Amount and the Owners do not receive the amounts payable under
the Building Contract Guarantee and the Performance Bonds, there will not be
sufficient funds to redeem the Allocated Principal Amount of such Notes. See
"Business--Building Contracts; Building Contract Guarantees and Performance
Bonds."

         Should a dispute arise under a Building Contract, the related Owner and
the Builders have agreed, pursuant to such Building Contract, to submit such
dispute to arbitration by either the Classification Society or the London
Maritime Arbitrators Association Inc. (each, an "Arbitrator"), as may be
mutually agreed to by the parties involved. The applicable Arbitrator may in any
particular dispute decide in favor of the Builders and as a result, delay or
eliminate such Owner's right to receive the payment of (i) any liquidated
damages, whether by an adjustment in the Purchase Price of the related Vessel or
a cash payment, or (ii) the Refund Amount. In such an event, to the extent that
such liquidated damages or the Refund Amount is necessary for the Issuer to make
interest payments on, or to redeem, any series of Exchange Notes and the
untendered Existing Notes, if any, as the case may be, the Issuer may not have
sufficient funds to satisfy its obligations under one or both of the Indentures.
See "Business--Building Contracts."

VOLATILITY OF VESSEL VALUES; POTENTIAL INSUFFICIENCY OF COLLATERAL

         Upon the acceptance of the Vessels by the Owners under the Building
Contracts, the Guarantees will be secured by a Mortgage on each Vessel granted
to the Collateral Agent. There can be no assurance that the value of each Vessel
will at any time equal or exceed the Allocated Principal Amount of the Notes for
such Vessel. The fair market value of the Vessels can be expected to fluctuate,
depending upon general economic and market conditions affecting the shipping
industry, competition from other shipping companies, demand for various types
and sizes of vessels, and other modes of transportation. There can be no
assurance that the proceeds from the sale of any Vessel in connection with the
Collateral Agent's exercise of remedies following an Event of Default would be
sufficient to redeem the Allocated Principal Amount of the Notes for such Vessel
or that any buyers would be available under the circumstances in which such sale
would occur. The Company is not required under the Indentures to maintain any
minimum value of any Vessel and there can be no assurance that the future value
of a Vessel will not be considerably less than its acquisition cost or the
Allocated Principal Amount of the Notes for such Vessel. If and to the extent
that amounts are owing under the Letter of Credit Reimbursement Agreement, then
the Letter of Credit Issuer shall have a claim to the proceeds of any sale of a
Vessel prior to the claim of the Holders of the Exchange Notes and the
untendered Existing Notes, if any. Furthermore, in certain circumstances the
extent to which the Mortgages may be enforced and the extent to which the
Mortgages will have priority over the claims of other creditors is limited. If
the proceeds from a sale of the Vessels are not sufficient to satisfy payments
due on the Exchange Notes and the untendered Existing Notes, if any, the Holders
of the Exchange Notes and the untendered Existing Notes, if any (to the extent
not repaid from the proceeds of the sale of the Vessels and other Collateral)
will have only unsecured claims against the remaining assets, if any, of the
Issuer and the Owners. See "The Mortgages."

DEPENDENCE ON KEY PERSONNEL OF THE MANAGER AND GEBAB

         The Company believes that its operations are dependent to some degree
upon the efforts of a small number of key management and operating personnel at
Navigator Gas Management Limited (the "Manager") and at GEBAB and its
affiliates, the loss of whom could adversely affect the Company. While the
success of the Company depends in part upon the Manager and upon GEBAB


                                      -22-
<PAGE>

and its affiliates and their personnel, the Company believes that there are
other qualified managers in the industry of seaborne transport of petrochemical
gases and LPG. However, there can be no assurance that the Company will be able
to engage such qualified managers or on what terms. See "Management."

COMPETITION

         The number of participants in the seaborne trade of petrochemical gases
is small and consists of a few large and experienced operators with greater
financial resources than the Company. Since the Company will be a new
participant in this field and has no operating history, it may not be able to
participate successfully in the gas carrier industry. See "Gas Carrier
Industry." TGE and its affiliates are not restricted from engineering, designing
and constructing gas storage and transportation plants and equipment for
competitors of the Company.

RISKS IN INTERNATIONAL OPERATIONS

         The majority of the revenues from operation of the Vessels is expected
to be derived from foreign operations and is subject, in varying degrees, to
risks inherent in doing business abroad. Future hostilities or other political
instability in the regions in which the Company conducts its operations could
affect the Company's trade patterns and could adversely affect the Company's
business and results of operations. See "Gas Carrier Industry--Demand for Gas
Carriers" and "The Mortgages--Insurance."

ENVIRONMENTAL AND OTHER REGULATIONS

         The Vessels and the operation of the Vessels must comply with extensive
and changing environmental protection laws and regulations. Compliance with
these laws and regulations may entail significant expenses, including expenses
for ship modifications and changes in operating procedures. These laws and
regulations could have a material adverse effect on the business and the
operations of the Owners. In particular, the United States Comprehensive
Environmental Response, Compensation, and Liability Act, as amended ("CERCLA"),
imposes strict liability on owners, operators, and demise charterers of vessels
for releases of hazardous substances (other than oil) from their vessels. In
addition, the United States Oil Pollution Act of 1990, as amended ("OPA 90"),
provides for strict liability for owners, operators and demise charterers of any
vessel for certain oil pollution incidents in the waters of the United States or
adjoining shorelines or in the exclusive economic zone. OPA 90 applies to all
vessels that trade in the United States or its territories or possessions or
operate in United States waters, even if such vessels do not carry oil as cargo.
Furthermore, certain states have enacted legislation that provides for liability
under circumstances comparable to those governed by CERCLA and OPA 90, without
the limitations on the amount of liability contained in the federal statutes.

         CERCLA and OPA 90 each require vessel owners and operators to furnish
the United States Coast Guard (the "Coast Guard") evidence of financial
responsibility sufficient to meet their potential liability. Insurance has been
one of the principal methods used to satisfy such requirements. Although certain
newly-formed insurance companies, which have been deemed acceptable guarantors
by the Coast Guard, have furnished the guarantees pursuant to the terms outlined
in the rule issued by the Coast Guard on March 7, 1996 relating to financial
assurance (the "Final Rule"), most of the protection and indemnity organizations
that traditionally provided insurance to ship owners and operators have refused
to furnish evidence of insurance to owners and operators of vessels entering
United States ports under the Final Rule. If an Owner intends to employ its
Vessel


                                      -23-
<PAGE>

within the territorial waters of the United States, such Owner must furnish
evidence of financial responsibility with respect to the Vessels to the Coast
Guard as required by the Final Rule. If such Owner is unable to comply with the
Final Rule, such Vessel will not be permitted to enter United States territorial
waters.

         In addition, the International Maritime Organization (the "IMO"), an
agency of the United Nations, recently adopted regulations designed to reduce
oil pollution in international waters. In complying with the IMO regulations,
the Owners and any charterer of the Vessels may be forced to incur additional
costs in meeting new maintenance and inspection requirements, in developing
contingency arrangements for potential spills and in obtaining insurance
coverage.

         Certain states in the United States and other countries have adopted or
are considering adopting stricter technical and operational requirements for
tankers. Additional laws and regulations may be adopted which would have a
material adverse effect on the business and the operations of
the Owners.

RISK OF LOSS AND LIABILITY; INSURANCE

         The operation of any ocean-going vessel carries an inherent risk of
catastrophic marine disasters, environmental mishaps, cargo and property losses
or damage and business interruptions caused by adverse weather and ocean
conditions, mechanical failures, human error, political action in various
countries, war, terrorism, piracy, labor strikes and other circumstances or
events. The Vessels will be operated throughout the world in any lawful trade
for which the Vessels are suitable, PROVIDED that, pursuant to the terms of the
Mortgages, the Vessels may not be employed in any manner or for any purpose
excepted by the insurance thereon. In the past, political conflicts have
disrupted shipping in the surrounding regions. Vessels trading in such regions
have also been subject to acts of terrorism and piracy. Any such event may
result in increased costs or the loss of revenues or assets, including a Vessel.

         The Company intends to maintain insurance consistent with industry
standards against these risks. However, there can be no assurance that all risks
will be adequately insured against, that any particular claim will be paid out
of such insurance or that the Company will be able to procure adequate insurance
coverage at commercially reasonable rates in the future. More stringent
environmental and other regulations may result in increased costs for, or the
lack of availability of, insurance against risks of environmental damage,
pollution, damages asserted against the Company or the loss of income resulting
from a vessel being removed from operations. Moreover, even if insurance
proceeds are paid to the Company to cover the financial losses incurred
following the occurrence of one of these events, there can be no assurance that
the Company's business reputation, and therefore its ability to obtain future
charters, will not be materially adversely affected by such event. Such an
impact on the Company's business reputation could have a material adverse effect
on the Company's business and results of operations. See "Mortgages--Insurance."

ENFORCEMENT OF MORTGAGES

         Each of the Vessels will be registered under the laws of the Republic
of Liberia. The Mortgages will be recorded pursuant to the laws of the Republic
of Liberia and the Isle of Man and will create preferred ship mortgage liens
under the maritime law thereof. In addition, in order to perfect the Mortgages
granted by the Owners, the Mortgages will also be filed in the Isle of Man.
Historically, Liberian ship mortgages have been enforced in major commercial
ports throughout the world. However, the priority that such mortgages will have
against the claims of other lien creditors


                                      -24-
<PAGE>

in an enforcement proceeding is generally determined by, and will vary in
accordance with, the laws of the country where a proceeding is brought.
Generally, such a preferred ship mortgage lien will rank prior to all subsequent
maritime liens other than certain other preferred maritime liens, including
liens for damages arising out of tort (including claims for oil pollution),
liens for crew's wages, liens for general average and salvage. Under Liberian
law, a preferred ship mortgage lien will also rank after certain other maritime
liens, including maritime liens for failure to pay tonnage taxes and annual
fees. Under United States law, a foreign preferred ship mortgage lien will also
rank after certain other maritime liens, including those for repairs, supplies,
towage, use of drydock or marine railways or other necessaries, performed or
supplied in the United States. Since each Vessel will trade throughout the world
and since a mortgage generally will be enforceable against a Vessel only in the
jurisdiction in which it is physically present, there can be no assurance that
if enforcement proceedings are commenced against a Vessel, the Vessel will be
located in a jurisdiction having the same mortgage enforcement procedures and
lien priorities as, for example, Liberia or the United States. However, upon the
occurrence of an event of default under a Mortgage, the Collateral Agent may be
able to effect control over the related Vessel to direct it to a desirable
jurisdiction for arrest of the Vessel pursuant to judicial foreclosure
proceedings. See "Mortgages--Remedies."

FRAUDULENT CONVEYANCE STATUTES

         The granting of the security interest in and to the Collateral could be
subject to review under relevant fraudulent conveyance statutes and other
applicable insolvency laws (the "Fraudulent Conveyance Laws") in a bankruptcy or
other proceeding involving one or more of the Owners and Holdings. Due to the
nature of the business of the Owners and Holdings and uncertainty as to where a
bankruptcy, vessel foreclosure or other relevant proceeding might be commenced,
it is not possible to predict where any such proceeding or attack might be
brought or made or the law that the court might apply.

         Under the Fraudulent Conveyance Law of the Isle of Man (the
jurisdiction in which each of the Owners and Holdings is incorporated), if a
court were to find that, with respect to any Owner or Holdings, at the time the
interests in the Collateral were granted (the "Transfer"), it (a) made such
Transfer with actual intent to prefer or defraud any present or future creditor,
(b) received less than a reasonably equivalent value or fair consideration for
the Transfer or (c) intended to incur, or believed that it would incur, debts
beyond its ability to pay as they matured (as the foregoing terms are defined in
or interpreted under the relevant Fraudulent Conveyance Laws), such court could
avoid the Transfer in whole or in part. To the extent that a Transfer by any
Owner or Holdings exceeds the consideration received by it, the determination of
whether the Transfer in question is a fraudulent conveyance depends on (1)
whether the Transfer so exceeds the value and benefit received by such Owner or
Holdings that, at least to the extent of such excess, the Owner or Holdings did
not receive reasonably equivalent value or fair consideration for the Transfer;
and, if so, then (2) whether following the valuation of the assets and
liabilities of such Owner or Holdings, it is determined that such Owner or
Holdings is or has been rendered insolvent. While there can be no assurance that
a court, viewing the transaction in hindsight, would determine that a particular
Owner or Holdings received fair value for its Transfer, or was not rendered
insolvent by such Transfer, to the extent it exceeded the value of the
consideration received by that Owner or Holdings, each Owner and Holdings
believes that it will receive proper consideration for its respective Transfer
and that no such Owner or Holdings will be rendered insolvent by the
contemplated Transfers. No assurance, however, can be given that a court would
concur with such belief.


                                      -25-
<PAGE>

RISKS RELATING TO ENFORCEMENT OF JUDGMENTS AGAINST HOLDINGS, THE ISSUER AND THE
OWNERS

         Holdings, the Issuer and each of the Owners are incorporated in the
Isle of Man. As a result, it may be difficult to obtain a judgment in the Isle
of Man in an original action or to enforce in the Isle of Man judgments obtained
in the United States courts and predicated upon United States securities laws.

LIMITATION ON CHANGE OF CONTROL

         Pursuant to the Indentures, in the event of a Change of Control, the
Issuer will be required to offer to purchase the Exchange Notes and the
untendered Existing Notes, if any, in whole or in part, at a price equal to 101%
of the principal amount thereof (determined on the date of purchase), as
described under "Description of the Exchange Notes--Mandatory Offers to Purchase
Exchange Notes--Offer to Purchase Upon Change of Control." As the Issuer has not
provided for any credit support to fund a Change of Control Offer, there can be
no assurance that sufficient funds will be available for the Issuer to fulfill
its mandatory purchase obligation.


ABSENCE OF PUBLIC MARKET FOR THE EXCHANGE NOTES

         The Existing Notes are currently owned by a relatively small number of
beneficial owners. The Existing Notes have not been registered under the
Securities Act and will continue to be subject to restrictions on
transferability to the extent that they are not exchanged for the Exchange
Notes. The Exchange Notes will constitute a new issue of securities with no
established trading market. Although the Exchange Notes will be permitted to be
resold or otherwise transferred by Holders who have met the conditions of the
Exchange Offer without compliance with the registration requirements under the
Securities Act, Navigator Gas Transport and the Owners do not intend to list the
Exchange Notes on any national securities exchange or to seek the admission
thereof to trading on the Nasdaq National Market. Accordingly, no assurance can
be given that an active public or other market will develop for the Exchange
Notes or as to the existence of or liquidity of the trading market for the
Exchange Notes. See "PLAN OF DISTRIBUTION."

EXCHANGE OFFER PROCEDURE

         The issuance of the Exchange Notes pursuant to the Exchange Offer will
be made only after a timely receipt by the Company or its agent of a properly
completed and duly executed Letter of Transmittal, or an agreement to be bound
thereby, and all other required documents. Therefore, Holders of Existing Notes
desiring to tender such Existing Notes in exchange for Exchange Notes should
allow sufficient time to ensure timely delivery. The Company is under no duty to
give notification of defects or irregularities with respect to tenders of
Existing Notes for exchange. Existing Notes that are not tendered or are
tendered but not accepted will, following the consummation of the Exchange
Offer, continue to be subject to the existing restrictions on transfer thereof,
and upon consummation of the Exchange Offer, the registration rights under the
Registration Rights Agreement generally will terminate. In addition, any Holder
of Existing Notes who tenders in the Exchange Offer for the purpose of
participating in a distribution of the Exchange Notes may be deemed to have
received restricted securities and, if so, will be required to comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. Each broker-dealer that receives
Exchange Notes for its own account in exchange for Existing Notes, where such
Existing Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge


                                      -26-
<PAGE>

that it will deliver a prospectus in connection with any resale of such Exchange
Notes. To the extent that Existing Notes are tendered and accepted in the
Exchange Offer, the liquidity of untendered and tendered but unaccepted Existing
Notes could be adversely affected. See "THE EXCHANGE OFFER."


                               THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

         The Existing Notes were issued by the Issuer on August 7, 1997, to
Credit Suisse First Boston Corporation and Cambridge Partners, L.L.C.
(collectively, the "Initial Purchasers"). The Initial Purchasers subsequently
placed the Existing Notes with qualified institutional buyers in reliance on
Rule 144A under the Securities Act. As a condition to the purchase of the
Existing 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 sale of the Existing Notes to the
Initial Purchasers, the Company would (i) file with the Commission a
Registration Statement under the Securities Act with respect to a registered
offer to exchange the Existing Notes for the Exchange Notes identical in all
material respects to the Existing Notes, (ii) use its respective reasonable best
efforts to cause such Registration Statement to become effective under the
Securities Act and (iii) use its reasonable best efforts to cause the Exchange
Offer to be consummated on the earliest practical date after such Registration
Statement becomes effective. The Company has agreed to keep the Exchange Offer
open for not less than 30 days. A copy of the Registration Rights Agreement has
been filed as an exhibit to the Registration Statement of which this Prospectus
is a part.

         Following the consummation of the Exchange Offer, Holders of the
Existing Notes who did not tender their Existing Notes generally will not have
any further registration rights under the Registration Rights Agreement, and
such Existing Notes will continue to be subject to certain restrictions on
transfer. Accordingly, the liquidity of the market for such Existing Notes could
be adversely affected.

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 Issuer will accept for exchange
any and all Existing Notes validly tendered and not withdrawn prior to 5:00
p.m., New York City time, on the Expiration Date. The Issuer, will issue up to
$217,000,000 principal amount of First Priority Exchange Notes in exchange for a
like principal amount of outstanding Existing First Priority Notes accepted in
the Exchange Offer, and up to $87,000,000 principal amount of Second Priority
Exchange Notes in exchange for a like principal amount of Existing Second
Priority Notes pursuant to the Exchange Offer. Holders may tender all or a
portion of their Existing Notes pursuant to the Exchange Offer. However,
Existing Notes may be tendered only in minimum denominations of $100,000 and
integral multiples of $1,000 in excess thereof.

         The form and terms of the Exchange Notes will be identical to the form
and terms of the Existing Notes except that (i) the Exchange Notes have been
registered under the Securities Act and hence will not bear legends restricting
the transfer thereof and (ii) the Holders of the Exchange Notes will not be
entitled to certain rights under the Registration Rights Agreement, which rights
generally will terminate upon consummation of the Exchange Offer. The Exchange
Notes will


                                      -27-
<PAGE>

evidence the same debt as the Existing Notes tendered in exchange therefor and
will be entitled to the benefits of the Indenture.

         As of the date of this Prospectus, $217,000,000 aggregate principal
amount of the Existing First Priority Notes and $87,000,000 aggregate principal
amount of the Existing Second Priority Notes were outstanding and registered in
the name of Cede & Co., as nominee for DTC. The Company has fixed the close of
business on ________, 1997, as the record date for the Exchange Offer for
purposes of determining the persons to whom this Prospectus, the Letter of
Transmittal, the Notice of Guaranteed Delivery and the Isle of Man Information
will be mailed initially.

         Holders of Existing Notes do not have any appraisal or dissenters'
rights under the General Corporation Law of the Isle of Man or the Indenture in
connection with the Exchange Offer. The Company intends to conduct the Exchange
Offer in accordance with the applicable requirements of the Exchange Act and the
rules and regulations of the Commission thereunder, including Rule 14e-1
thereunder.

         The Issuer shall be deemed to have accepted validly tendered Existing
Notes when, as and if the Issuer has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering Holders
for the purpose of receiving the Exchange Notes from the Issuer.

         If any tendered Existing Notes are not accepted for exchange because of
an invalid tender, the occurrence of certain other events set forth herein or
otherwise, the certificates for any such unaccepted Existing Notes will be
returned, without expense, to the tendering Holder thereof as promptly as
practicable after the Expiration Date.

         Holders who tender Existing 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 Notes
pursuant to the Exchange Offer. The Company has agreed to pay all charges and
expenses in connection with the Exchange Offer. See "--FEES AND EXPENSES" and
"--TRANSFER TAXES."

EXPIRATION DATE; EXTENSIONS; AMENDMENTS

         The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
___________, 1997 (or longer if required by applicable law).

         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 by means of a prospectus supplement that will be distributed to the
registered Holders, and, depending upon the significance of the amendment and
the manner of disclosure to the registered Holders, the Company will extend the
Exchange Offer for by the number of days equal to the period between the giving
of such notice to the delivery of a prospectus supplement.

         Without limiting the manner in which the Company may choose to make
public announcement of any delay, extension, amendment or termination of the
Exchange Offer, the Company shall have no obligation to publish, advertise or
otherwise communicate any such public announcement, other than by making a
timely release to the Dow Jones News Service.


                                      -28-

         Holders of Existing Notes do not have any appraisal or dissenters'
rights in connection with the Exchange Offer. The Company intends to conduct the
Exchange Offer in accordance with the applicable requirements of the Exchange
Act and the rules and regulations of the Commission thereunder.

INTEREST ON THE EXCHANGE NOTES

         The Exchange Notes will be deemed to accrue interest from August 7,
1997 (the date of original issuance of the Existing Notes) or from the date of
the last periodic payment of interest on such Existing Notes, whichever is
later. Interest on the Exchange Notes will be payable semi-annually on each June
30 and December 31, commencing on December 31, 1997.

PROCEDURES FOR TENDERING

         Only a Holder of Existing Notes may tender such Existing Notes in the
Exchange Offer. To tender in the Exchange Offer, a Holder must either (i)
complete, sign and date the Letter of Transmittal, or a facsimile thereof, have
the signatures thereon guaranteed (if required by the Letter of Transmittal) and
mail or otherwise deliver such Letter of Transmittal or such facsimile, together
with the Existing Notes and any other required documents, to the Exchange Agent
or (ii) in the case of a book-entry transfer, confirm book-entry transfer of the
Existing Notes into an equal principal amount of Exchange Notes into the
Exchange Agent's account at DTC, in either case prior to 5:00 p.m., New York
City time, on the Expiration Date. To be tendered effectively, the Existing
Notes, Letter of Transmittal and other required documents must be received by
the Exchange Agent at the address set forth below under "--EXCHANGE AGENT" or,
if book-entry transfer is used, electronic instructions with regard to the
Existing Notes, the Letter of Transmittal and all other required documents must
be received by DTC, in each case prior to 5:00 p.m., New York City time, on the
Expiration Date. A Holder of Existing Notes may also tender in the Exchange
Offer by complying with the procedure set forth under "--GUARANTEED DELIVERY
PROCEDURES."

         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 Existing Notes at DTC for the purpose of facilitating the Exchange Offer,
and subject to the establishment thereof, any financial institution that is a
participant in DTC's system may make book-entry delivery of the Existing Notes
by causing DTC to transfer such Existing Notes into the Exchange Agent's account
with respect to the Existing Notes in accordance with DTC's procedures for such
transfer.

         DTC's Automated Tender Offer Program is the only method of processing
exchange offers through DTC. To accept the Exchange Offer through ATOP,
participants in DTC must send electronic instructions to DTC through DTC's
communication system in place of sending a signed, hard copy Letter of
Transmittal. DTC is obligated to communicate those electronic instructions to
the Exchange Agent. To tender Existing Notes through ATOP, the electronic
instructions sent to DTC and transmitted by DTC to the Exchange Agent must
contain the character by which the participant acknowledges its receipt of, and
agrees to be bound by, the Letter of Transmittal.

         By executing or electronically confirming the Letter of Transmittal,
each Holder will make to the Company the representations set forth below in the
second paragraph under "--RESALE OF EXCHANGE NOTES."


                                      -29-
<PAGE>

         The tender by a Holder and the acceptance thereof by the Issuer will
constitute agreement between such Holder and the Issuer in accordance with the
terms and subject to the conditions set forth herein and in the Letter of
Transmittal.

         THE METHOD OF DELIVERY OF EXISTING NOTES, THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH DTC, TO THE EXCHANGE
AGENT IS AT THE ELECTION AND RISK OF THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT
IS RECOMMENDED THAT HOLDERS USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL
CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE
AGENT BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR EXISTING NOTES
SHOULD BE SENT TO ANY OF THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE
BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE
ABOVE TRANSACTIONS FOR SUCH HOLDERS.

         Any beneficial owner whose Existing Notes are registered in the name of
a broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered Holder promptly and instruct such
registered Holder to tender on such beneficial owner's behalf.

         Signatures on the Letter of Transmittal or a notice of withdrawal, as
the case may be, must be guaranteed by an Eligible Institution (as defined
below) unless the Existing 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" on the Letter of Transmittal or
(ii) for the account of an Eligible Institution. In the event that signatures on
a Letter of Transmittal or a notice of withdrawal, as the case may be, are
required to be guaranteed, such guarantee must be 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 (an "Eligible Institution").

         If the Letter of Transmittal is signed by a person other than the
registered Holder of any Existing Notes listed therein, such Existing Notes must
be endorsed or accompanied by a properly completed bond power, signed by such
registered Holder as such registered Holder's name appears on such Existing
Notes with the signature thereon guaranteed by an Eligible Institution.

         If the Letter of Transmittal or any Existing Notes or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and unless waived by the
Company, evidence satisfactory to the Company of their authority to so act must
be submitted with the Letter of Transmittal.

GUARANTEED DELIVERY PROCEDURES

         Holders not holding through DTC or Cede & Co. who wish to tender their
Existing Notes and (i) whose Existing Notes are not immediately available, (ii)
who cannot deliver their Existing Notes, the Letter of Transmittal or any other
required documents to the Exchange Agent or (iii) who cannot complete the
procedures for book-entry transfer, prior to the Expiration Date, may effect a
tender if:


                                      -30-
<PAGE>

                                          (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
         transmission, mail or hand delivery) setting forth the name and address
         of the Holder, the certificate number(s) of such Existing Notes and the
         principal amount of Existing Notes tendered, stating that the tender is
         being made thereby and guaranteeing that, within five New York Stock
         Exchange trading days after the Expiration Date or the execution of the
         Notice of Guaranteed Delivery, the Letter of Transmittal (or facsimile
         thereof), together with the certificate(s) representing the Existing
         Notes (or a confirmation of book-entry transfer of such Existing Notes
         into the Exchange Agent's account at the Book-Entry Transfer Facility)
         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), as well as the
         certificate(s) representing all tendered Existing Notes in proper form
         for transfer (or a confirmation of book-entry transfer of such Existing
         Notes into the Exchange Agent's account at the Book-Entry Transfer
         Facility) and all other documents required by the Letter of
         Transmittal, are received by the Exchange Agent within five New York
         Stock Exchange trading days after the Expiration Date.

WITHDRAWALS OF TENDERS

         Except as otherwise provided herein, tenders of Existing Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration
Date.

         To withdraw a tender of Existing Notes in the Exchange Offer, a written
or facsimile transmission notice of withdrawal (or a written or electronic ATOP
transmission notice of withdrawal for DTC participants) must be received by the
Exchange Agent at its address set forth herein (or received into the Exchange
Agent's account at DTC) prior to 5:00 p.m., New York City time, on the
Expiration Date. Any such notice of withdrawal must (i) specify the name of the
person having deposited the Existing Notes to be withdrawn (the "Depositor"),
(ii) identify the Existing Notes to be withdrawn, (iii) be signed or confirmed
by the Holder in the same manner as the original signature on or confirmation of
the Letter of Transmittal by which such Existing Notes were tendered (including
any required signature guarantees) or be accompanied by documents of transfer
sufficient to have the Trustee with respect to the Existing Notes register the
transfer of such Existing Notes into the name of the person withdrawing the
tender and (iv) specify the name in which any such Existing Notes are to be
registered, if different from that of the Depositor. If Existing Notes have been
delivered pursuant to the procedures for book-entry transfer described above,
any notice of withdrawal must also specify the name and number of the account at
DTC, and must otherwise comply with DTC's procedures. 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 Existing 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 Existing Notes so withdrawn are
validly retendered. Any Existing Notes which have been tendered but which are
not accepted for exchange, will be returned to the Holder thereof without cost
to such Holder as soon as


                                      -31-
<PAGE>

practicable after withdrawal, rejection of tender or termination of the Exchange
Offer. Properly withdrawn Existing Notes may be retendered by following one of
the procedures described above under "--PROCEDURES FOR TENDERING" at any time
prior to the Expiration Date.

EXCHANGE AGENT

         United States Trust Company of New York has been appointed as Exchange
Agent for the Exchange Offer. Questions and requests for assistance or for
additional copies of this Prospectus, the Letter of Transmittal or the Notice of
Guaranteed Delivery should be directed to the Exchange Agent addressed as

                             United States Trust Company of New York

                             New York, NY 10003
                             Attn: Corporate Trust Services

                             BY FACSIMILE:

                             United States Trust Company of New York
                             (212) 420-6152; confirm by telephone (800) 548-6565

FEES AND EXPENSES

         The principal solicitation is being made by mail; however, additional
solicitation may be made by telegraph, telephone or in person by officers and
regular employees of the Company and its affiliates. No additional compensation
will be paid to any such officers and employees who engage in soliciting
tenders. The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers or others soliciting
acceptances of the Exchange Offer. The Company, however, will pay the Exchange
Agent reasonable and


                                      -32-
<PAGE>

customary fees for its services and will reimburse it for its reasonable
out-of-pocket expenses in connection therewith and pay other registration
expenses, including fees and expenses of the Trustee, filing fees, blue sky fees
and printing and distribution expenses.

         The estimated cash expenses to be incurred in connection with the
Exchange Offer will be paid or reimbursed by the Company and are estimated in
the aggregate to be in excess of
$_______.

TRANSFER TAXES

         The Company will pay all transfer taxes, if any, applicable to the
exchange of the Existing Notes pursuant to the Exchange Offer. If, however,
certificates representing the Exchange Notes or the Existing Notes for principal
amounts not tendered or accepted for exchange are to be delivered to, or are to
be issued in the name of, any person other than the registered Holder of the
Existing Notes tendered, or if tendered Existing 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 the Notes
pursuant to the Exchange Offer, then the amount of any such transfer taxes
(whether imposed on the registered Holder or any other person) will be payable
by the tendering Holder.

ACCOUNTING TREATMENT

         The Exchange Notes will be recorded at the same carrying value as the
Existing Notes, which is face value, as reflected in the accounting records of
the Company on the date of exchange. Accordingly, no gain or loss for accounting
purposes will be recognized.

RESALE OF EXCHANGE NOTES

         Based on interpretations by the staff of the Commission set forth in
no-action letters issued to third parties, the Company believes that Exchange
Notes issued pursuant to the Exchange Offer in exchange for the Existing Notes
may be offered for resale, resold or otherwise transferred by any Holder of such
Exchange Notes (other than any such Holder which 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 Holder's business and such Holder does not intend to participate
and has no arrangement or understanding with any person to participate in the
distribution of such Exchange Notes. Any Holder who is an affiliate of the
Company, who acquires the Exchange Notes outside the ordinary course of its
business or who tenders in the Exchange Offer with the intention to participate,
or for the purpose of participating, in a distribution of the Exchange Notes may
not rely on the position of the staff of the Commission enunciated in EXXON
CAPITAL HOLDINGS CORPORATION (available May 13, 1988) and MORGAN STANLEY & CO.
INCORPORATED (available June 5, 1991), or similar no-action letters, but rather
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction. In addition,
any such resale transaction should be covered by an effective Registration
Statement containing the selling security holders information required by the


                                      -33-
<PAGE>

applicable provisions of Item 507 or 508, as appropriate, of Regulation S-K of
the Securities Act. Each broker-dealer that receives Exchange Notes for its own
account in exchange for Existing Notes, where such Existing Notes were acquired
by such broker-dealer as a result of market-making activities or other trading
activities, may be a statutory underwriter and must acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Notes. See
"PLAN OF DISTRIBUTION."

         Each broker-dealer that receives Exchange Securities for its own
account in exchange for Notes, where such Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Securities. See "PLAN OF DISTRIBUTION."

         By tendering in the Exchange Offer, each Holder will represent to the
Company that, among other things, (i) the Exchange Notes acquired pursuant to
the Exchange Offer are being obtained in the ordinary course of business of the
person receiving such Exchange Notes, (ii) the Holder has no arrangement or
understanding with any person to participate in the distribution of such
Exchange Notes and (iii) the Holder acknowledges that if it participates in the
Exchange Offer for the purpose of distributing the Exchange Notes (a) it must,
in the absence of an exemption therefrom, comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
resale of the Exchange Notes and cannot rely on the no-action letters referenced
above and (b) failure to comply with such requirements in such instance could
result in such Holder incurring liability under the Securities Act for which
such Holder is not indemnified by the Company. Further, by tendering in the
Exchange Offer, each Holder represents to the Company either that it is not an
"affiliate" (as defined under Rule 405 of the Securities Act) of the Company or,
if it may be deemed an "affiliate" of the Company that such Holder understands
and acknowledges that the Exchange Notes may not be offered for resale, resold
or otherwise transferred by that Holder without complying with the applicable
registration and prospectus delivery requirements of the Securities Act. A
Holder who is a broker-dealer must also acknowledge to the Company that it
acquired the Existing Notes as a result of market-making activities or other
trading activities.

CONSEQUENCES OF FAILURE TO EXCHANGE

         As a result of the making of this Exchange Offer, the Company generally
will have fulfilled its obligations under the Registration Rights Agreement, and
Holders of Existing Notes who do not tender their Existing Notes generally will
not have any further registration rights under the Registration Rights Agreement
or otherwise. Accordingly, any Holder of Existing Notes that does not exchange
such Existing Notes for Exchange Notes will continue to hold such Existing Notes
and will be entitled to all the rights, and subject to all the limitations,
applicable thereto under the Indenture, except to the extent such rights or
limitations, by their terms, terminate or cease to have further effectiveness as
a result of the Exchange Offer.

         Existing Notes that are not exchanged for Exchange Notes pursuant to
the Exchange Offer will remain restricted securities. Accordingly, such Existing
Notes may be resold only (i) to the Company (upon redemption thereof or
otherwise), (ii) pursuant to an effective Registration


                                      -34-
<PAGE>

Statement under the Securities Act, (iii) so long as the Existing Notes are
eligible for resale pursuant to Rule 144A, to a qualified institutional buyer
within the meaning of Rule 144A under the Securities Act in a transaction
meeting the requirements of Rule 144A, (iv) outside the United States to a
foreign person pursuant to the exemption from the registration requirements of
the Securities Act provided by Regulation S thereunder or (v) pursuant to
another available exemption from the registration requirements of the Securities
Act, in each case in accordance with any applicable securities laws of any state
of the United States.

         Because the Exchange Offer is for any and all Existing Notes, the
number of Existing Notes tendered and exchanged in the Exchange Offer will
reduce the principal amount of Existing Notes outstanding. As a result, the
liquidity of any remaining Existing Notes may be substantially reduced.

OTHER

         Participation in the Exchange Offer is voluntary, and Holders should
carefully consider whether to accept. Thacher Proffitt & Wood, New York, New
York, as counsel for the Company, has passed upon the legality of the Exchange
Notes. None of the Company, the Owners or any of their respective
representatives is making any representation to any offeree of the Exchange
Notes offered hereby regarding the legality of an investment by such offeree or
purchaser under appropriate legal investment or similar laws (which regulate the
nature and extent of permitted investments in certain securities for certain
institutional investors). Each Holder of the Existing Notes should consult with
its own advisors as to legal, tax, business, financial and related aspects of
participation in the Exchange Offer.

         The Company, may in the future seek to acquire untendered Existing
Notes in open market or privately negotiated transactions, through subsequent
exchange offers or otherwise. The Company, has no present plans to acquire any
Existing Notes that are not tendered in the Exchange Offer or to file a
registration statement to permit resales of any untendered Existing Notes.

                                 USE OF PROCEEDS

         The Exchange Offer is intended to satisfy certain of the Company's
obligations under the Registration Rights Agreement. 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 Existing Notes in like
principal amount, the form and terms of which are substantially the same as the
form and terms of the Exchange Notes, except as otherwise described herein. The
Existing 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 increase in the indebtedness of the Company.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

         The Issuer was formed by Holdings as an Isle of Man public limited
company for the purpose of establishing, owning and financing the Owners. Each
Owner was formed as an Isle of Man private limited company for the purpose of
building and operating one of the Vessels. As of the Original Closing Date,
neither the Issuer nor any of the Owners had any operating history and each had
nominal capitalization.

         Holdings has entered into the Building Contracts, the Technical
Supervision Agreement, the Technical Management Agreement and the Commercial
Management Agreement. Holdings has assigned to each Owner the Building Contract
for such Owner's Vessel and has assigned to the Manager the Technical
Supervision Agreement, the Technical Management Agreement and the Commercial
Management Agreement. In addition, each Owner has entered into the Management
Agreement with the Manager.

         On or before the Original Closing Date, the Issuer (i) received the
proceeds, net of the Initial Purchasers' discounts and commissions and financial
advisory fees, from the Offerings and lent a portion of such net proceeds to the
Owners on a joint and several basis pursuant to a promissory note, dated the
Original Closing Date (the "Intercompany Note"), (ii) paid certain fees and
expenses in connection with the Offerings, (iii) deposited $225.4 million into
the Pre-Funding Account and $47.3 million into the Capitalized Interest Account
and (iv) entered into the Letter of Credit Reimbursement Agreement.

OPERATIONS

         The operations of the Issuer will be limited to (i) owning the Owners,
(ii) receiving payments under the Intercompany Note, (iii) making payments of
interest and principal on the Notes, and (iv) fulfilling its obligations under
the Indentures, the Intercreditor Agreement, the Letter of Credit
Reimbursement Agreement and the Registration Rights Agreement.

         Between the Original Closing Date and the Delivery Date of each Vessel,
the operations of each Owner will consist solely of (i) entering into commercial
arrangements in relation to the future operations of the Vessels, (ii) managing
the construction of the Vessels, (iii) making payments of Management Fees, (iv)
paying installments under the Building Contracts, (v) fulfilling its obligations
under the Management Agreement and (vi) fulfilling its obligations under its
Guarantee.

         On and after the Delivery Date of each Vessel, the operations of each
Owner will consist solely of (i) operating, maintaining, insuring and using the
Vessel and conducting activities related thereto, (ii) receiving payments under
charters, contracts of affreightment and other contracts relating to the
employment of its Vessel, (iii) receiving proceeds from the sale, if any, of its
Vessel, (iv) making payments of interest and principal on the Intercompany Note
and any other permitted indebtedness, (v) making payments of Management Fees,
(vi) fulfilling its obligations under the Management Agreement and (vii)
fulfilling its obligation under its Guarantee.


                                      -39-
<PAGE>

CAPITAL RESOURCES AND LIQUIDITY

         Through the Contractual Delivery Date of each Vessel, interest on the
Allocated Principal Amount of the Notes for such Vessel that has not been
accepted by the related Owner will be payable from amounts on deposit in the
Capitalized Interest Account. To the extent the Delivery Date for a Vessel is
delayed, either the Builders will pay liquidated damages which will be deposited
into the Pre-Funding Account or the final installment due under such Building
Contract will be decreased, or both. See "BUSINESS--BUILDING CONTRACTS." In
either event, the amount available in the Pre-Funding Account will be sufficient
to pay interest accrued on the Allocated Principal Amount of the Notes for such
Vessel during the period of delay. After the Delivery Date of a Vessel, each
Owner's sources of funds will be earnings on its Vessel, earnings on Temporary
Cash Investments (as defined) and the proceeds from the sale, if any, of its
Vessel. In addition, the Issuer has obtained a Letter of Credit in a total
amount of $50.0 million of which $45.5 million is available as a liquidity
support, available to fund payments of interest to the Noteholders under certain
circumstances, and $4.5 million of which will be available as a working capital
facility for certain amounts payable by the Owners. Under certain circumstances,
interest on the Second Priority Exchange Notes and the untendered Existing
Second Priority Notes, if any, may be paid through the issuances of additional
Second Priority Exchange Notes. See "DESCRIPTION OF THE EXCHANGE NOTES--TERMS OF
THE EXCHANGE NOTES--SECOND PRIORITY EXCHANGE NOTES." The Company does not have,
nor does it expect to have in the future, any other source of capital for
payment of its debt service obligations under the Notes. See "RISK
FACTORS--LIMITED PURPOSE NATURE OF THE ISSUER, OWNERS AND HOLDINGS."

RESULTS OF OPERATIONS

         The Company's results of operations will depend on the earnings from
the Vessels and from Permitted Investments and its level of operating expenses.

                              GAS CARRIER INDUSTRY

OVERVIEW

         Gas carriers transport three main types of liquified gases: (i)
petrochemical gases such as ethylene, propylene, VCM, butadiene and crude C4,
(ii) LPG products such as ethane, propane and butane and (iii) ammonia.
Petrochemical gases, LPG and ammonia, under normal ambient temperatures, are
found in a gaseous state. In order to reduce their volume and facilitate
handling, these products are liquified for seaborne transportation in gas
carriers.

         There are several types of gas carriers which use different techniques
to liquify and transport cargoes, including (i) fully- pressurized vessels that
rely solely upon high pressure to liquify gases, (ii) fully-refrigerated vessels
that have the ability to maintain cargo in a liquified state by cooling gases to
a temperature of -48(degree)C and (iii) semi-refrigerated vessels which employ a
combination of refrigeration and pressurization techniques. Generally, LPG and
ammonia gases are transported in fully-refrigerated vessels ranging in size from
20,000 to 80,000 cbm for long-haul, large volume transportation. Petrochemical
gases are generally carried in semi-refrigerated or fully- pressurized vessels
under 20,000 cbm. A limited number of semi-refrigerated vessels have the
capability of carrying ethylene, which requires cooling temperatures to
- -104(degree)C, and ethane, which requires cooling temperatures to -82(degree)C.
To a lesser extent, these smaller vessels are also used to transport LPG and
ammonia over short-haul routes.

         Charter rates and vessel values for gas carriers are influenced by the
supply of and demand for seaborne gas cargo carrying capacity. The demand for
gas carrier capacity is primarily determined by industrial and consumer demand
for petrochemical gases and derivative products and the distance that such gases
must be transported. Industrial and consumer demand for petrochemical gases and
derivative products is, in turn, affected by general economic conditions, trends
in personal consumption and manufacturing, exports and imports and the capacity
of chemical plants, crackers and refineries worldwide. The supply of gas carrier
capacity is a function of the size of the existing fleet, the number of
newbuildings being delivered and the scrapping of older vessels.

SUPPLY OF GAS CARRIERS

         EXISTING WORLD GAS CARRIER FLEET

         The following table sets forth the composition of the world gas carrier
fleet which includes vessels which transport petrochemical gases, LPG and
ammonia as of June 1997:

         0--5,000 CBM. The smallest class of vessels is comprised primarily of
fully-pressurized vessels which carry petrochemical gases and LPG. There are
also some semi-refrigerated vessels in the 2,000--5,000 cbm range including
several 4,000 cbm ethylene-capable carriers. The trading patterns of these
vessels generally consist of short-haul "cross-trading" routes, which include
hauls throughout the Far East, the Mediterranean, northwestern Europe and the
Caribbean.

         5,001--10,000 CBM. The vessels in this class are primarily
semi-refrigerated vessels and carry petrochemical gases. There are also some
fully- pressurized vessels in this class. The trading patterns of these vessels
are mainly short cross-trades with some longer hauls. These vessels usually
trade Transatlantic, between the Mediterranean and northern Europe, and between
the Arabian Gulf and Southeast Asia/Far East. The majority of the existing
ethylene carriers are in this size class.

         10,001--25,000 CBM. In this class there are both semi-refrigerated and
fully-refrigerated vessels. The majority of vessels under 20,000 cbm are
semi-refrigerated while the majority of vessels over 20,000 cbm are
fully-refrigerated. Petrochemical gases, including ethylene for ethylene-capable
carriers, are the primary cargoes traded on semi-refrigerated vessels. The
semi-refrigerated vessels under 12,500 cbm participate primarily in short-haul
trading while the vessels over 12,500 cbm also operate in the long-haul markets.
LPG and ammonia are the major products traded in the fully-refrigerated vessels,
mostly on long-haul routes.

         25,001--50,000 CBM. The vessels in this class are all modern
fully-refrigerated vessels which carry LPG and ammonia on both long-haul and
cross-trade routes, except for one non-ethylene-capable 30,000 cbm
semi-refrigerated vessel.

         50,001--60,000 CBM. The vessels in this class are all
fully-refrigerated and transport LPG and ammonia. LPG trading routes include
both long-haul trades between the Arabian Gulf and the Mediterranean and
cross-trades in the North Sea and Europe. Ammonia trading routes are typically
shorter cross-trades.

(b)      Includes the Vessels.


         The seven newbuilds in the world ethylene-capable fleet include the
Vessels as well as two vessels being built by Skibsaksjeselskapet Solvang, which
at 12,500 cbm are each 56.8% of the capacity of one of the Vessels.

         Several factors in the gas carrier industry limit supply growth: (i)
the importance of having a sufficient size fleet to engage in efficient
triangular trading; (ii) the operational and technical expertise required to
operate gas carriers; (iii) the limited number of shipyards which have the
expertise required to build gas carriers, which incorporate sophisticated gas
plant systems; and (iv) the strong demand for the construction of less
technically-demanding vessels, such as oil tankers, drybulk carriers and
container carriers, which currently limit shipyard availability.

TRENDS IN PETROCHEMICAL GAS PRODUCTION AND SEABORNE TRADE

         World production and seaborne trade of petrochemical gases have shown a
strong and stable growth trend over the past several years, and this trend is
expected to continue. The following table sets forth historical and forecast
production and seaborne trade data for the principal petrochemical gases and
LPG, demonstrating both the rate and stability of global production growth and
the stable percentage of production which is transported by sea. Although the
LPG market is not the primary targeted market, the Company believes that the
projected strong growth in seaborne LPG trading will absorb a significant
portion of overall gas carrier capacity.

DEMAND FOR GAS CARRIERS

         The transportation of petrochemical gases is a rapidly-developing
market fueled by industrial and consumer demand for products derived from
petrochemical gases and the planned new construction and expansion of existing
petrochemical production facilities worldwide. The petrochemical gases and LPG
described below are used in many products, including plastics, synthetic-based
products, chemicals and rubber, and as feedstocks.

         CARGOES AND TRADING PATTERNS

         The following is a brief description of the principal targeted cargoes
and their trading patterns:

         ETHYLENE. Ethylene is derived from the cracking of petroleum
feedstocks. It is the key building block in the production of a wide range of
materials used in industrial and consumer items including plastics, polyester
fibers and resins, large-volume thermoplastic resins, organic chemicals, kitchen
equipment, anti-freeze and various products used in insulation and packing.
Seventy percent of global ethylene production is used in the production of
various plastics and automobile parts and the balance is used in the production
of antifreeze, resins and fibers. Worldwide seaborne trade of ethylene rose at a
compound annual growth rate of 3.7% from 2.0 million tonnes in 1990 to 2.5
million tonnes in 1996. Historically, the exporting regions of ethylene have
been the Middle East, Europe and Latin America. The growth in imports of
ethylene over this period was driven primarily by economic development in India,
which resulted in an increase in ethylene imports from 0 tonnes


                                      -45-
<PAGE>

to 397,000 tonnes. European exports rose by 195,000 tonnes during this time
period. In the next five years India, recently an importer of ethylene, is
expected to become a producer of ethylene, along with Malaysia, Thailand and
Singapore while the Mediterranean region and China are anticipated to increase
their imports. By the beginning of the next decade, world ethylene capacity is
expected to exceed 100.0 million tonnes, representing a 7.4% compound annual
growth rate over the estimated 1996 capacity of 81.0 million tonnes. World
ethylene demand is expected to grow at a similar rate during this period.

         PROPYLENE. Propylene is produced as a by-product in the making of
ethylene and gasoline and is utilized in the production of consumer goods such
as car components, carpets, plastic pipes and household articles for which there
is typically strong demand in fast-growing economies. Polypropylene, a
derivative of propylene, accounts for 52.0% of propylene usage and is used as a
feedstock for plastics. Propylene is also used in the manufacture of acrylic
fiber, styrofoam, pharmaceuticals, cumene and glue. Between 1990 and 1996,
worldwide seaborne trade in propylene increased at a compound annual growth rate
of 2.8% from 1.5 to 1.8 million tonnes. The Far East showed the most significant
increase in imports during this time period, from 121,000 tonnes in 1990 to
355,000 tonnes in 1996, with exports serviced principally from the United States
and Europe. In the future, Middle Eastern exports are expected to increase as
new production facilities are introduced in the region. Imports of propylene,
especially by the growing Far Eastern plastic industry, should ensure continued
growth of the seaborne trade.

         VINYL CHLORIDE MONOMER (VCM). VCM is produced by the cracking of
ethylene dichloride and requires the input of chloride and ethylene. VCM is
primarily used in the manufacturing of PVC articles. Major end-user markets
include residential construction and irrigation systems. The manufacture of PVC
piping accounts for 35.0% of the VCM produced. The balance of VCM production is
used in the manufacture of such items as window frames and wire and cable. The
United States is the primary exporter of VCM and Southeast Asia and Latin
America are the principal importers. VCM exports from the United States are
expected to increase and the Far East is expected to become a larger importer.

         BUTADIENE. Butadiene is produced in the cracking of ethylene. Butadiene
is primarily used in the making of plastic products for building construction
and rubber for the automobile manufacturing industry. Rubber accounts for 80.0%
of butadiene consumption. South Korea and Europe have traditionally been large
exporters of butadiene, while the United States and the Far East have
traditionally been the largest importers. Far Eastern exports of butadiene are
expected to decrease as domestic demand grows. Worldwide seaborne trade of
butadiene rose at a compound annual growth rate of 2.1% from 555,000 tonnes in
1990 to 628,000 tonnes in 1996. North America was the primary importer of
butadiene accounting for 258,000 tonnes in 1996. Exports from Europe are
expected to be maintained in the future, but are unlikely to increase
significantly. Inter-Latin American butadiene trade is expected to increase.

         LIQUIFIED PETROLEUM GAS (LPG). LPG is produced as a by-product either
from the production of natural gas or refining of crude oil. The primary uses of
LPG are as fuel for transportation, residential and commercial heating, and as a
feedstock for the production of petrochemicals. LPG is produced primarily in the
North Sea, as a result of natural gas production, and the Middle East, as a
refining by-product. Exports of LPG are expected to grow significantly over the
next several


                                      -46-

years. Japan is the world's single largest importer of LPG. Europe and the
United States are expected to see increased imports of LPG. The seaborne trade
of LPG was 42.1 million tonnes in 1996, which represents 5.0% compound annual
growth from 1990. The North Pacific (including Japan) imported 18.7 million
tonnes of LPG in 1996, while Europe and the Middle East were the largest
exporters of LPG during the period, transporting 9.8 million tonnes in 1996. The
Company views the transportation of ethane, a feedstock for petrochemical
products that requires cooling to -82(degree)C for liquification, as an emerging
opportunity for the Vessels.

         PLANNED NEW CONSTRUCTION AND EXPANSION OF PETROCHEMICAL PRODUCTION
         FACILITIES

         Petrochemical gases are used in the production of a vast array of
chemicals and new production technologies are allowing plastic to displace
metal, cotton, wood and other materials in an increasing number of end-user
products. As a result, the use of petrochemical gases is expanding worldwide.
The following table summarizes the expected new construction and expansion of
petrochemical production facilities over the period from 1997 to 2001:

         Since the seaborne trade of petrochemical gases began in the early
1980's, terminal storage facilities have grown steadily, providing access to
larger, more efficient vessels with increased economies of scale. For example,
the first generation of ethylene terminals had a storage capacity of
8,000-15,000 cbm. By the late 1980's the maximum storage capacity had reached
30,000 cbm. New production facilities are currently planned and under
construction with storage capabilities of up to 60,000 cbm. The Company believes
that this trend will support the transport of larger parcels of petrochemical
gases resulting in greater demand for the Vessels.

THE CHARTER MARKET

         THE CHARTERING PROCESS

         The chartering of vessels for a specified period of time or to carry a
specific cargo is an integral part of the market for seaborne transportation of
liquified gases. The charter market, consisting of a worldwide network of
brokers specializing in the gas industry, is well established and efficient. The
chartering process begins when a producer, user or trader of petrochemical gases
identifies the need to transport a cargo or cargoes from one port to another.
The charterer typically contacts a broker or group of brokers to determine the
availability of suitable vessels to transport the specified cargo. The charterer
then chooses from an array of available vessels and seeks to negotiate the most
favorable economic terms for its transportation requirements. Typically, the
agreed terms are based on standard industry charterparties prepared to
streamline the negotiation and documentation processes.

         TYPES OF CHARTERS

         Charters may be arranged on a spot basis for the immediate hiring of a
vessel, usually for a single voyage, or through longer term arrangements, such
as contracts of affreightment and time or bareboat charters. Contracts of
affreightment are agreements by vessel owners to transport a specified cargo on
a specified route on a regular basis. Contracts of affreightment function as a
long-term series of spot charters, except that the owner is not required to use
a specific vessel to transport the cargo, but instead may use any vessel in its
fleet. Contracts of affreightment benefit vessel owners by providing a
guaranteed level of employment over a standard trading route. An owner with an
efficient fleet configuration can schedule its vessels in a triangular trading
pattern in order to minimize ballast trips and idle time, thereby achieving high
capacity utilization and enhancing revenues.

         A time charter is a contract for the hire of a vessel for a certain
period of time, with the vessel owner being responsible for providing the crew
and paying operating costs, while the charterer is responsible for fuel and
other voyage costs. As with a time charter, a bareboat charter is a contract to
hire a vessel for a period of time with the exception that under a bareboat
charter the charterer is responsible for operating the vessel and pays all
associated operating costs of the vessel during the charter.

<PAGE>

         COMPARISON TO OTHER SHIPPING MARKETS

         Unlike other shipping markets, such as the crude oil tanker market,
producers, users and traders of petrochemical gases generally do not own or
charter on a long-term basis their own fleet of vessels to transport their
cargoes. Instead, cargo owners rely on a small group of large vessel operators
to provide all freight services. This market structure provides cargo owners
with the flexibility to respond quickly and efficiently to changes in trading
patterns, while providing vessel owners with limited competition from captive
fleets.

INDUSTRY PARTICIPANTS

         The number of participants involved in the seaborne trade of
petrochemical gases is small and consists of few large and experienced
operators. There are currently two significant participants in the ethylene
carrier segment with vessels over 10,000 cbm. The largest owner is Sig. Bergesen
ASA ("Bergesen"). Bergesen controls the Igloo Pool (a cooperative marketing
venture among several owners) of 16 vessels ranging in size from 8,000 cbm to
12,000 cbm, most of which were built in the 1980's. Exmar NV has a small fleet
of three 10,500 cbm ethylene-capable vessels.

         In the semi-refrigerated, non-ethylene carrier market, Handygas,
controlled by Bergesen, and A.P. M0ller are the major participants. Handygas has
a fleet of 10 semi-refrigerated vessels, the majority of which were built in the
1970's. The average size of these vessels is 12,000 cbm. M0ller's fleet of 12
semi-refrigerated vessels is newer and ranges in size from 15,000 cbm to 20,000
cbm.

                                    BUSINESS


GENERAL

         The Company was formed in 1997 for the purpose of building and
operating a fleet of five state-of-the-art 22,000 cbm semi-refrigerated
ethylene-capable gas carriers. The Vessels are designed to transport the entire
range of petrochemical gases, including ethylene, propylene, VCM, butadiene and
crude C4, as well as LPG, such as ethane, propane and butane. There are no
ethylene-capable semi-refrigerated gas carriers currently operating or under
construction that will be larger than the Vessels. Each Vessel will have four
separate gas cargo tanks, segregated pumping and piping systems and a separate
deck tank, allowing each Vessel to carry up to three separate cargoes
simultaneously.

         Upon their construction, the Vessels will be among the most versatile
gas carriers in the world in terms of cargo options, ease and speed of loading
and discharging cargoes and adaptability for route scheduling. The foregoing
capabilities will permit the Company to minimize operating costs, reduce voyage
times and maximize vessel utilization. In addition, the Vessels' larger cargo
capacities, compared to the existing ethylene-capable fleet, offer significant
economies of scale, especially for long-haul transport.

BUSINESS STRATEGY

         The Company's business strategy is to take advantage of the strong
demand for seaborne transportation of petrochemical gases and LPG resulting from
the worldwide expansion in the production, use and trade of petroleum
by-products. The Company's fleet will supply transportation services to existing
customers of certain of the Shareholders of Holdings including major oil,
chemical and trading companies. The key elements of this strategy include:

         INTEGRATED CHARTERING STRATEGY. Charterers of gas carriers rely on
short and long-term contracts of affreightment and, to a lesser extent, time and
spot charters, allowing them to respond quickly and efficiently to the changing
trading patterns of the petrochemical gas market. The Company intends to take
advantage of these market dynamics by building a portfolio of contracts of
affreightment with major customers. Such contracts are expected to be from three
to five years in length and would provide the Vessels with a high level of
continuous employment. The Company also intends to use the spot market and, to a
lesser extent, time charters of the Vessels to achieve maximum capacity
utilization and minimize ballast trips and idle time. This strategy will be
implemented by MarLink, the commercial manager of the Vessels. MarLink is a
leading commercial manager of vessels in the petrochemical gas market.

         The Manager is currently negotiating contracts of affreightment for the
employment of the Vessels in the ethylene and propylene trades. One contract
would guarantee a minimum of 10 voyages and a maximum of 20 voyages per annum
for a full cargo of propylene from the Americas to the Mediterranean region. The
second contract would ensure a minimum of 18 voyages and a maximum of 28 voyages
per annum for a full cargo of ethylene from various loading ports to the
Mediterranean region. Each contract would be for a five-year period with freight
rates for each voyage to be based on market rates. If consummated, these
contracts could provide a base-load of


                                      -50-
<PAGE>

continuous employment for the Vessels during the terms thereof. However, there
can be no assurance that these contracts will be entered into.

         MAXIMIZE ETHYLENE BUSINESS. Historically, ethylene has generally
achieved an approximate 10-15% premium over charter rates for other
petrochemical gas cargoes. As ethylene frequently trades along the same routes
as other petrochemical gases, the Vessels' multiple tank configuration should
enable the Company to maximize the proportion of its freight mix accounted for
by ethylene, without sacrificing cargo capacity utilization or route efficiency.
Based on historical trends, as well as the increasing size of production
facilities, the Company also believes that the average size of ethylene freights
will increase, thereby enhancing the competitiveness of the Vessels.

         BUILD VERSATILE VESSELS WITH MULTI-CARGO CAPABILITY. The Vessels will
be among the most versatile petrochemical gas carriers in the world given their
ability to carry the full range of petrochemical gases and transport up to three
segregated cargoes simultaneously. The Company believes that these larger,
multiple-tank vessels will provide a competitive advantage over other operators
in the petrochemical gas freight market. In addition, the Vessels will offer
improved operating efficiencies due to their higher speed and shorter loading
and discharge times as compared to many less sophisticated vessels. The Company
has chosen the Builders because of their previous experience in the building of
gas carriers with TGE, a leading engineering firm in the production of gas
plants. See "BUSINESS -- THE VESSELS" and "--THE BUILDERS AND TGE."

         MAXIMIZE VESSEL UTILIZATION. The Company believes that its fleet size
of five Vessels, each with four tanks and the ability to carry up to three fully
segregated cargoes, will allow it to adopt triangular trade patterns which
minimize ballast trips. In addition, the Vessels' ability to carry up to three
cargoes simultaneously will give the Company the potential to service up to 15
charterers at any one time. The Company believes that the size of the Vessels
will also be attractive to charterers with substantial long-haul transport
requirements. The Company's fleet size and configuration will provide the
operational flexibility necessary to meet the logistical demands of managing
complex trading patterns.

THE VESSELS

         The Vessels will be state-of-the-art gas carriers. The Company believes
that the size and configuration of the Vessels, as well as the features
incorporated therein, will make them more attractive to charterers than other
vessels. As a result, the Company expects the Vessels to realize
higher-than-average levels of utilization in the transport of high value
petrochemical gas cargoes as compared to other gas carriers, significantly
enhancing the earnings potential of each Vessel.

         The Vessels will be semi-refrigerated, combining refrigeration and
pressurization to maintain their cargoes in a liquified state. This will allow
the Vessels to load products at varying temperatures from different terminals.
In addition to pre-cooled cargoes, the Vessels will have the ability to load
cargoes that cannot maintain their required liquid temperatures prior to
loading, due to distances traveled by pipeline from production facilities to
vessels, by accepting these cargoes under pressure and cooling them onboard the
Vessels during the voyage. The load time of these cargoes is thereby reduced
since the cargoes do not need to be cooled prior to loading. Unlike
semi-refrigerated vessels, fully-refrigerated vessels are only able to load
cargoes in a cooled state, requiring those vessels to


                                      -51-
<PAGE>

cool products prior to loading. This requirement slows product loading and
limits the number of terminals which can be efficiently serviced by such
vessels.

         The nitrogen generator and deck tank on each of the Vessels will allow
it to prepare its tanks for the next cargo while en route to the next load port.
This will result in time savings of as much as three days on some voyages, as
tank preparation would otherwise have to be carried out in port. These features
provide a significant benefit to charterers and terminal operators by improving
their terminal utilization. The 22,000 cbm carrying capacity of the Vessels will
also be beneficial to charterers and terminal operators by reducing the number
of loading and discharging operations, the duration of such operations and the
associated costs.

         The Vessels will sail under the Liberian flag, with a certification
from the Classification Society. The crew for each Vessel will be trained in
accordance with the highest standards. Each crew will consist of 6 to 7 officers
and 12 to 13 seamen. Upon delivery, each Vessel, including its machinery,
equipment and outfitting, is required to be classed with the Classification
Society and shall be distinguished in the record by the symbol of +100 A5 E
"Liquified Gas Carrier Type 2G" +MC E, AUT INERT. In order for a Vessel to be
accepted by the Owner, it is required to comply with the laws, rules,
regulations, recommendations and requirements as set out in the specifications
attached to the related Building Contract (the "Specifications").

         Located in Shanghai, Jiangnan was founded in 1865 and is a modern,
fully-equipped shipyard that is among the largest shipyards under the
supervision and control of China State Shipbuilding Corporation, which also
controls CSTC, its trading and export subsidiary. Jiangnan designs, builds,
repairs and converts many kinds of vessels including gas carriers. It also
designs, manufactures and erects various specialized machinery and electrical
equipment, non-standardized equipment, pressure vessels, port machinery and
steel structures in accordance with the regulations and requirements of the
world's major classification societies and shipping and building safety
treaties.

         China's first generation of submarines and the first self-designed
10,000 dwt ocean-going ship were built by Jiangnan in the 1950's and 1960's,
respectively. A fleet of oceanographic and scientific survey vessels was built
in the 1970's to support the launching of a rocket and man-made satellite in
China. Since 1980 many vessels built by Jiangnan have entered the international
market, including various types of merchant ship cargo vessels and LPG vessels
built for companies located in Germany, the United States, Italy, Norway,
Singapore, Hong Kong and other countries. Some of Jiangnan's recent export
clients include Mitsubishi Corporation, Neptune Orient Lines Ltd., World Wide
Shipping Agency Ltd., Lasco Shipping Co., Canada Steamship Lines and B. Skaugen
Shipping AS.

         Jiangnan has previous experience with TGE and is currently completing
the construction of two 16,500 cbm LPG/ammonia gas carriers for Bernard Schulte
GmbH, a large German shipowner. Jiangnan has also built the following types of
vessels and major components: 4,200 cbm


                                      -53-

semi-refrigerated ethylene carriers; 3,000 cbm fully-pressurized LPG carrier;
floating production storage units; 68,500 dwt panamax oil tankers;
65,000/70,000/73,000 dwt panamax bulk carriers; 50,000 dwt open-hatch bulk
carriers; 28,000/34,000 dwt lakes-fitted bulk carriers; 20,000 dwt bulk
carriers; 4,000 roll-on/roll-off car carriers and UT714 anchor
handling-tug-supply vessels. Jiangnan is also currently constructing other
sophisticated types of vessels including a 70,800 dwt self-unloader, a 1,021 TEU
fast-speed feeder and a 13,700 dwt chemical carrier.

         TGE is an indirect subsidiary of Tractebel, S.A., a major Belgian
public company engaged in the utility and engineering industries. TGE is a world
leader in the engineering, design and construction of gas storage and
transportation plants and equipment. In addition, it manufactures port
facilities for the off-loading and receiving of liquified gases, gas
liquification and handling systems, chemical and gas plants for installation on
carriers, storage facilities for liquified gases and chemicals, gas bottling
plants, gas terminals and metering stations, vaporization, transmission lines
and compressor stations and package plants for recovery of products from
associated gases. TGE is a leading provider of turnkey operations. TGE will
design the complex gas plants utilized on the Vessels. TGE will also supervise
the construction and erection of the Vessels' gas plants through its permanent
office in Shanghai. Since 1980, TGE has been involved in the installation of gas
plants for 36 gas carriers, 18 of which are ethylene-capable. TGE will act as a
subcontractor to Jiangnan under each Building Contract and as such will be
responsible for supplying materials for construction of the gas plant and
supervising its installation.

         Jiangnan and TGE have worked together on the construction of the
following gas carriers and components:

(a)      Assuming delivery of the Vessel occurs on its Contractual Delivery
         Date.

(b)      This payment shall be payable to the Builders with respect to a Vessel
         only if and when Collateral Agent has received evidence of delivery
         pursuant to the Building Contract with respect to each other Vessel
         having a Contractual Delivery Date prior to the Contractual Delivery
         Date of such Vessel.

(c)      May not total due to rounding.


                                      -55-

         Each Building Contract provides for upward and downward adjustments to
the Purchase Price of a Vessel, which adjustments are made through increases or
decreases in the final installment of the Purchase Price. The Purchase Price of
a Vessel may be increased by $13,000 per day for each day that such Vessel is
delivered earlier than its Contractual Delivery Date. In addition, in the event
of certain delays in the delivery of such Vessel or the failure of such Vessel
to comply with certain specifications, the Builders are required to pay
liquidated damages to its Owner.

         Under each Building Contract, the Builders may postpone the delivery of
a Vessel to a certain number of days beyond its Contractual Delivery Date
without incurring liability for liquidated damages (the "Permissible Delay
Period"). The Permissible Delay Period for each of the Vessels is as follows:
(i) 60 days for Vessel 1, (ii) 45 days for Vessel 2 and (iii) 30 days for each
of Vessels 3, 4 and 5. The aggregate Permissible Delay Period for all five
Vessels, however, is limited to 150 days. Therefore, for example, if the
Builders utilize the full Permissible Delay Period for each of Vessels 1, 2 and
3, then an aggregate Permissible Delay Period of 15 days is available for the
remaining Vessels before the Builders are required to pay liquidated damages to
the respective Owner of Vessels 4 or 5, or both.

         During the period of delay following the Permissible Delay Period up to
and including 210 days beyond the Contractual Delivery Date of a Vessel (the
"First Delay Period"), the Builders must pay liquidated damages to the related
Owner in the form of a reduction in the final installment of the Purchase Price
of such Vessel in an amount equal to $11,000 per day for the first 90 days of
delay beyond the Extended Delivery Date and $14,500 per day for each day of
delay thereafter.

         The Builders have the option to extend the Delivery Date of a Vessel
beyond the First Delay Period until March 31, 2001 (the "Second Delay Period")
by paying liquidated damages monthly in advance at a rate of $18,000 per day for
the first six-month period, $20,000 per day for the second six-month period and
$22,000 per day thereafter up to and including March 31, 2001, which liquidated
damages are expected to be sufficient to pay the interest on the Allocated
Principal Amount of the Notes for such Vessel. In the event the Builders fail to
make timely payment of such liquidated damages, the Owner may (i) waive its
right to such payment and elect instead to receive a further reduction in the
final installment of the Purchase Price (in addition to any such reduction
during the First Delay Period) equal to the amount of the liquidated damages
waived or (ii) rescind the related Building Contract and demand payment of the
Refund Amount. An Owner's waiver of the advance payment of liquidated damages
for any given month will not constitute a waiver by the Owner of its right to
demand the payment at any later date of such liquidated damages or to demand the
advance payment of monthly liquidated damages for any subsequent months of
delay.

         The Purchase Price of a Vessel may also be reduced, as a result of
liquidated damages payable by the Builders, because of the Builders' failure to
construct such Vessel in compliance with specifications relating to guaranteed
speed, fuel consumption, deadweight and cargo tank
capacity.

         RESCISSION AND TERMINATION OF THE BUILDING CONTRACTS

         An Owner may rescind a Building Contract upon the occurrence of certain
events of default by the Builders, which arise from the non-delivery of a Vessel
or the failure of a Vessel to meet minimum requirements relating to speed, fuel
consumption, deadweight and cargo tank capacity. The


                                      -56-
<PAGE>

events of default relating to non-delivery of a Vessel are (i) the failure by
the Builders to make payments of liquidated damages monthly in advance during
the Second Delay Period and the Owner does not waive its right to receive the
payment of such liquidated damages and (ii) the failure to deliver the Vessel by
March 31, 2001. The Owner may also rescind a Building Contract if any of the
following deficiencies exists with respect to a Vessel: (i) its speed is one
knot or more below the guaranteed speed of 16.5 knots; (ii) its fuel consumption
is 8.0% or greater than the guaranteed fuel consumption set forth in the
Specifications; (iii) its deadweight is more than 800 tonnes below the
guaranteed deadweight of 22,800 tonnes; and (iv) its cargo tank capacity is more
than 400 cbm below the guaranteed cargo tank capacity of 22,000 cbm.

         In addition, a Building Contract will be automatically terminated if,
prior to the Delivery Date, (A)(i) a Vessel is seized by the Chinese government,
(ii) the Builders fail to obtain the necessary licenses, permits and other
authorizations from the Chinese government for the construction, delivery and
export from China of such Vessel or (iii) a total loss occurs with respect to a
Vessel and (B) the Builders do not elect to continue performing under such
Building Contract.

         Under the cross-default provisions of the Building Contracts, in the
event a Building Contract is rescinded by an Owner or automatically terminated,
the other Owners that have not accepted delivery of their Vessel will be deemed
to have also rescinded their respective Building
Contracts.

         MANDATORY REDEMPTION OF THE NOTES AND THE REFUND AMOUNT

         In the event a Building Contract is rescinded or automatically
terminated, the Issuer is required, under the terms of the Indentures, to redeem
the Allocated Principal Amount of the Notes for the relevant Vessel and the
Builders must, under such Building Contract, pay the Owner a scheduled amount
(the "Refund Amount"). The Refund Amount together with the amounts held in the
Pre-Funding Account and the Capitalized Interest Account with respect to such
Building Contract are expected to be sufficient to pay the Rescission Amount
calculated as of the date on which the Notes are scheduled for redemption.

         The Refund Amount is due and payable upon the delivery by an Owner to
the Builders of its notice of rescission of a Building Contract or upon the
automatic termination of the Building Contract, as the case may be. If the
Builders delay the payment of the Refund Amount, interest (the "Refund
Interest") will accrue on the Refund Amount at a rate of 10% per annum for each
day of delay from and including the date on which the Owner's notice of
rescission is delivered or on which the Building Contract is automatically
terminated, as the case may be, until but not including the date on which
Builder makes payment in full of the Refund Amount plus any Refund Interest.

         GAS TRIALS

         Prior to the Delivery Date, the Vessel's gas plant will be mechanically
completed by the Builders and a running test of the equipment of the gas plant
and a function test of its system utilizing either inert gas or dry air shall be
made by the Builders. The tests will be repeated until the results are deemed by
the Classification Society to be in conformity with the Building Contract and
the Specifications.


                                      -57-
<PAGE>

         After the Delivery Date, the Owner shall, at its own cost and expense,
carry out an additional gas trial in accordance with the trial program furnished
by TGE. The gas trial is required to be made no later than 45 days after the
Delivery Date subject to certain exceptions and shall be certified by the
Classification Society. If the gas plant is not in conformity with the Building
Contract and the Specifications, the Builders must remedy any such
non-conformity to the satisfaction of the Owner, the Classification Society and
any other relevant authority. If such non-conformity delays the use of a Vessel,
the Owner's only contractual remedy is to receive payment of liquidated damages
of up to $200,000 from the Builders, which payment is not supported by either
the related Building Contract Guarantee or the Performance Bonds.

         WARRANTY OF QUALITY

         The Builders, for a period of 12 months following the Delivery Date of
a Vessel, guarantee the Vessel, its hull and machinery and all parts and
equipment thereof that are manufactured or furnished or supplied by the Builders
and/or their sub-contractors under the Building Contract including material and
equipment (excluding any parts for the Vessel which have been supplied by or on
behalf of the Owner) against all defects which are due to defective materials,
and/or poor workmanship or failure to construct in conformity with the
Specifications.

BUILDING CONTRACT GUARANTEES AND PERFORMANCE BONDS

         The Export-Import Bank of China (the "Building Contract Guarantor" or
"EXIM") has delivered an Irrevocable Letter of Guarantee with respect to each
Vessel (collectively, the "Building Contract Guarantees") and an Irrevocable
Performance Bond relating to all five Vessels (the "Builders Performance Bond"),
each on behalf of the Builders, and Generale de Banque S.A. ("Generale" and,
together with EXIM, the "Performance Bond Guarantors") has delivered an
Irrevocable Performance Bond (the "TGE Performance Bond" and, together with the
Builders Performance Bond, the "Performance Bonds"), on behalf of TGE, relating
to all five Vessels. The Building Contract Guarantees and the Performance Bonds
severally and in the aggregate unconditionally guarantee payment to the Owners
of the Refund Amount and any Refund Interest. Each Building Contract Guarantee
guarantees the payment to the relevant Owner of the portion of the Refund Amount
relating to all installment payments that have been made on or prior to the date
on which such Building Contract is rescinded by such Owner or automatically
terminated. The Builders Performance Bond covers an aggregate amount of up to
$32.5 million for all five Vessels and the TGE Performance Bond covers an
aggregate amount of up to $16.2 million for all five Vessels. The availability
of the TGE Performance Bond, however, is conditioned upon the payment by EXIM to
the Owners of the maximum amount of $32.5 million guaranteed under the Builders
Performance Bond.

         Pursuant to the terms and conditions of the Intercreditor Agreement,
the Collateral Agent shall draw under the Performance Bonds an amount equal to
the Rescission Amount (as defined) (calculated as of the date on which the
Exchange Notes and the untendered Existing Notes, if any, are scheduled for
redemption) less the sum of (i) the amounts held in the Pre-Funding Account and
in the Capitalized Interest Account and (ii) the amount payable under the
applicable Building Contract Guarantee or Guarantees, as the case may be.


                                      -58-
<PAGE>

         Each of the Building Contract Guarantees and the Performance Bonds
became effective upon the payment of the first installment of the Purchase Price
under the Building Contracts, which payment was made on the Original Closing
Date with the net proceeds of the Offerings. Each Building Contract Guarantee
will expire with respect to the related Building Contract upon the earliest of
(i) the receipt by the Owner of the amount guaranteed thereunder, (ii) the
confirmation to the Building Contract Guarantor of acceptance of the related
Vessel and (iii) May 1, 2001. Each of the Performance Bonds will expire upon the
earliest of (i) the receipt by any of the Owners of any payment thereunder, (ii)
the confirmation to the applicable Performance Bond Guarantor of the acceptance
of all remaining Vessels and (iii) May 1, 2001.

         EXIM is owned by the government of the People's Republic of China and
its long-term debt is rated A3 by Moody's Investor Service Inc. ("Moody's"). The
long-term debt of Generale is rated A1 by Standard & Poor's Ratings Services, a
division of The McGraw-Hill Company, Inc. ("S&P") and Aa3 by Moody's.

MARKETING AND COMMERCIAL MANAGEMENT

         MARKETING STRATEGY

         The marketing strategy of the Owners is to build a portfolio of
contracts of affreightment for petrochemical gas cargoes in order to maximize
the revenue potential of the Vessels. The Owners intend to concentrate on
transporting primarily petrochemical gases, particularly ethylene, and
secondarily LPG. The Owners do not intend to transport ammonia cargoes but may
pursue such employment as dictated by the overall market for gas transport. On
or prior to the Original Closing Date, the Issuer, Holdings and each of the
Owners have engaged the Manager to manage their daily commercial and technical
operations pursuant to a management agreement (the "Management Agreement"),
including providing administrative services, causing the compliance of the
Owner's covenants in the Indentures and monitoring GEBAB's performance under the
Technical Supervision Agreement, Technical Management Agreement and the
Commercial Management Agreement. The Manager, through the expertise of its
principal employees, is implementing and will implement the Owners' marketing
strategy.

         The Manager believes that contracts of affreightment will offer the
advantages of longer-term employment and the exploitation of the triangular
trading capabilities of the Vessels. Triangular trading in this context refers
to the ability of the Vessels to trade multiple cargoes on a trade route in
which cargoes are discharged and new cargoes are loaded in a single geographic
region. Such triangular trading can be distinguishable from the "A to B" trade
characteristic of crude transport in which the vessel carries a cargo from the
loading port to the discharge port and returns ballast to the loading port. The
Manager may supplement the employment of the Vessels with spot charters and
timecharters as opportunities arise in the market. The Manager does not intend
to pursue bareboat charters with respect to the Vessels.

         The Manager is currently negotiating two contracts of affreightment for
the employment of the Vessels in the ethylene and propylene trade. One contract
would guarantee a minimum of 10 voyages and a maximum of 20 voyages per annum
for a full cargo of propylene from the Americas to the Mediterranean Region. The
second contract would ensure a minimum of 18 voyages and a


                                      -59-
<PAGE>

maximum of 28 voyages per annum for a full cargo of ethylene from various
loading ports to the Mediterranean Region. Each contract would be for a
five-year period with freight rates for each voyage to be based on market rates.
The Management of the Company believes that if consummated, these contracts
could provide a base-load of continuous employment for the Vessels during the
terms thereof. However, there can be no assurance that these contracts will be
entered into.

         The Manager is implementing and will implement a marketing strategy on
behalf of the Owners through the marketing efforts of its principal employees
and through the Commercial Management Agreement with GEBAB. The Owners intend to
supplement the marketing efforts of the Manager and GEBAB by maintaining a
non-exclusive brokerage relationship with Xenon.

         The Company has preliminarily identified Chevron Products Company,
Pequiven, Norsk Hydro, Enichem, PMI, Dow Chemicals, Mitsui USA, and Sunkyong
America, Inc., among others, as potential customers in the petrochemical market.
It has identified Exxon Chemical Company, Shell Chemicals, Texaco Chemical
Company, Statoil, Yukong, Dow Chemicals and Mitsubishi International
Corporation, among others, as potential customers in the LPG market. There is
currently no contractual arrangement between the Company and any of these
customers for the transportation of cargoes by the Vessels, and there can be no
assurance that any of these potential customers will employ the Vessels upon
their acceptance by the Owners under each Building Contract.

         COMMERCIAL MANAGEMENT AGREEMENT

         The Manager on behalf of the Owners is party to a Master Commercial
Marketing and Services Agreement (the "Commercial Management Agreement"), dated
as of February 28, 1997, with GEBAB whereunder GEBAB has agreed to commercially
manage the Vessels. Upon the completion and delivery to the Owners of each
Vessel, GEBAB will solicit cargo to be transported by such Vessels. GEBAB's
responsibilities include the marketing of each Vessel, the preparation and
negotiation of all contracts of affreightment or other types of charters for
each Vessel, operation of all agreements entered into, including invoicing and
accounting for and handling of employment-related expenses, calculation of
demurrage and laytime expenses and the coordination of all claims with each
Owner's P&I Clubs.

         GEBAB, through its affiliate MarLink, will arrange for all income
earned with respect to each Vessel to be paid directly into a lock-box account
(the Revenue Account) to be held by the Collateral Agent. Pursuant to the
Commercial Management Agreement, a management fee of 2.0% of net revenues from
operations received in a given Calendar Quarter (as defined) is payable
quarterly by the Manager from the Operating Account (as defined) on the 16th day
following the end of each calendar quarter which shall end on the last day of
March, June, September and December (each, a "Calendar Quarter"). GEBAB, through
its affiliate MarLink, will deliver a quarterly statement (a "Quarterly
Statement") reflecting the net operating revenues of the Vessels received in the
Revenue Account, all actual employment related expenses incurred duly supported
by the relevant documents and vouchers, resulting net time charter earnings
during the elapsed period, days employed as well as idle days and reasons
therefor. Each Quarterly Statement shall be due within 15 days after the end of
each Calendar Quarter. Each month, the Owners will be provided with an


                                      -60-
<PAGE>

estimate of employment-related expenses. Actual expenses will be paid to the
Collateral Agent upon the presentation of invoices therefor to the Manager from
amounts held in the Operating Account.

         The term of the Commercial Management Agreement with respect to each
Vessel shall be a period of three years commencing on the delivery to the
related Owner of such Vessel, and the Commercial Management Agreement will
continue after the end of the three-year term indefinitely until terminated by
GEBAB or any Owner pursuant to the Commercial Management Agreement. The
obligations of GEBAB under the Commercial Management Agreement will be assigned
to MarLink by novation. As a condition to such novation, GEBAB shall deliver a
guarantee.

OPERATIONS

         The Manager intends to implement the Owners' operating strategy by
administering a technical management agreement between GEBAB and the Owners.
GEBAB intends to assign its responsibilities under the technical management
agreement to its affiliate Martime.

         TECHNICAL MANAGEMENT AGREEMENT

         GEBAB and the Manager on behalf of the Owners are parties to the Baltic
and International Maritime Council (BIMCO) Standard Ship Management Agreement
(the "Technical Management Agreement"), dated as of February 28, 1997,
whereunder Holdings, as predecessor to the Owners, appointed GEBAB to act as
technical manager of the Vessels. Pursuant to the Technical Management
Agreement, GEBAB, through its affiliate Martime, will provide for and supervise
the crew for each Vessel, supervise and maintain the technical management of
each Vessel, arrange for all insurances for each Vessel, provide accounting
services for each Vessel, arrange for the supply of provisions for each Vessel,
including bunker fuel, and provide for the operation of each Vessel.

         GEBAB, through its affiliate Martime, will present an annual budget
three months before the end of each calendar year. The projected budget for
1999, the first year a Vessel is expected to be delivered and become
operational, is $190,000 per month, which amount is expected to be sufficient to
cover crew cost and basic operating expenses (includes insurance cover, deck
equipment, cargo plant, engine up-keep, luboils and chemicals, and provision for
dry docking). Following the agreement on the operating budget for the Vessels,
on the first Business Day of each month in such budgeted year, GEBAB, through
its affiliate Martime, shall prepare and present to the Manager its estimate of
the working capital requirement for each Vessel and shall request the Manager to
disburse the funds required to run the Vessel against invoices presented by it.
In addition, GEBAB, through its affiliate Martime, will present invoices
representing occasional or extraordinary items of expense such as emergency
repair costs, additional insurance premiums, bunkers or provisions.

         Pursuant to the Technical Management Agreement, a management fee of
2.0% of net operating revenues for the first six years of operation and 2.5%
thereafter will be payable by the Manager from the Operating Account quarterly
in advance on the first day of the calendar quarter based on a pre-approved
budget (the "Budgeted Management Fee") submitted by GEBAB, through its affiliate
Martime. The Budgeted Management Fee shall be adjusted quarterly in arrears for
each Calendar Quarter and the difference between the actual management fee
earned for a Calendar Quarter and the aggregate Budgeted Management Fee paid for
such Calendar Quarter shall be


                                      -61-
<PAGE>

reflected in the Budgeted Management Fee payable on the next day immediately
following the end of any Calendar Quarter.

         The term of the Technical Management Agreement with respect to each
Vessel shall be for a period of three years commencing on the delivery to each
Owner of such Vessel, and the Technical Management Agreement will continue after
the end of the three-year term indefinitely until termination by either GEBAB or
any Owner pursuant to 90 days' written notice. The obligations of GEBAB under
the Technical Management Agreement will be assigned to Martime by novation. As a
condition to such novation, GEBAB shall deliver a guarantee.

INSPECTION

         CHEMICAL DISTRIBUTION INSTITUTE

         CDI was founded by the major participants in the liquid and gas
transportation market and is controlled by the oil majors, including Exxon
Chemical Company, Chevron Products Company, British Petroleum (BP) Chemicals,
Shell Chemicals and Mobil Chemical Company. CDI has set common vessel inspection
criteria for the safe transportation of hazardous cargo at sea, according to the
standards of all individual member companies. CDI has also implemented
standardized vessel inspections to replace the need for each particular member
to inspect and rate each vessel on a regular basis. These inspections are
generally more thorough and extensive than the inspections carried out by the
individual members. CDI is fully-implemented in Europe and the Americas and is
in the process of being implemented in Asia. The Company intends to fully meet
all CDI code requirements and receive certification.

         INTERNATIONAL SAFETY MANAGEMENT

         ISM publishes a code (the "ISM Code") which sets forth standards
applicable for internationally acceptable procedures in safe contemporary ship
management. The ISM Code has been endorsed by the IMO and plays an important
role in international ship management. Entities that do not obtain certification
under the ISM Code have increasing difficulties in marketing their services. The
certification under the ISM Code are carried out by classification societies
acting as auditors and must be complied with by 1999. The provisions of ISO 9002
are not mandatory. The Company intends to fully meet all ISM Code requirements
and receive certification.

ENVIRONMENTAL REGULATIONS

         The business and operations of the Company and any charterer of the
Vessels are materially affected by governmental regulation in the form of
international conventions and national, state, and local laws and regulations in
force in the jurisdictions in which the Vessels operate, as well as in the
country or countries of registration. Because such conventions, laws and
regulations are often revised, and have become increasingly stringent, the
Company cannot predict the ultimate costs of compliance with such revised
conventions, laws and regulations or the impact thereof on the resale price or
useful life of the Vessels.

         COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION, AND LIABILITY ACT
         OF 1980 ("CERCLA")

         CERCLA was enacted to respond to environmental contamination caused by
the release of hazardous substances from facilities and vessels. CERCLA provides
that an owner, operator or demise charterer of a vessel, from which there is a
release or threatened release of certain defined hazardous substances, not
including crude oil or its fractions, is liable for the following: (i) removal
costs or remedial action taken by the United States or a local government; (ii)
other necessary costs of response incurred by any other person consistent with
the National Contingency Plan (the primary guidance document for CERCLA response
actions); (iii) damages for injury to, destruction of, or loss of natural
resources, including the cost of assessing such injury, destruction, or loss;
and (iv) the costs of any health assessment or studies permitted under CERCLA.
Since the Vessels may carry substances as cargo which are hazardous substances
under CERCLA, a discharge or threat of discharge of such cargo could result in
CERCLA liability and have a materially adverse effect on the Owners and the
operation of the Vessels.

         Total liability under CERCLA for each release from a vessel is limited
to the greater of $300 per gross tonne or $5,000,000 for vessels that carry
hazardous substances as cargoes. However, these limits will not apply if: (i)
the release or threat of release of a hazardous substance was the result of
willful misconduct or willful negligence within the privity or knowledge of an
owner or operator, or the primary cause or the release was a violation of
applicable safety, construction or operating standards or regulations; or (ii)
the owner or operator fails or refuses to provide all reasonable cooperation and
assistance requested by a responsible public official in connection with
response activities. In addition, a responsible party under CERCLA could face
punitive damages equal to three times the government's cost of response and
remediation if the responsible party fails, without sufficient cause, to
undertake a removal or remediation action ordered by the government.

         CERCLA requires that owners and operators of vessels establish and
maintain with the Coast Guard evidence of insurance or of qualification as a
self-insurer or other evidence of financial responsibility sufficient to meet
their potential strict liability limit under CERCLA. The Coast Guard adopted the
Final Rule, which requires evidence of financial responsibility equal to the
aggregate of the CERCLA strict liability limit and the OPA 90 liability limit
demonstrated by insurance, surety bond, self-insurance or guarantee. Without
such certificates, vessels are prohibited from trading to United States ports or
in United States waters. The Owners have agreed to furnish evidence of financial
responsibility with respect to the Vessels to the Coast Guard as required by the
Final Rule. Certain newly-formed insurance companies, which have been deemed
acceptable guarantors by the Coast Guard, have furnished the guarantees pursuant
to the Final Rule.

         The Final Rule may also be satisfied by evidence of a surety bond or
guarantee. However, the financial credit of some owners and operators may make
the furnishing of surety bonds or guarantees economically infeasible.
Additionally, vessel owners and operators may give evidence of self-insurance to
satisfy the Coast Guard's regulations. Under these provisions, the shipowner or
operator must have net worth and working capital, measured in assets located in
the United States against liabilities located anywhere in the world, that each
exceed the applicable amount of financial responsibility. If the Owners of the
Vessels fail to comply with the Final Rule, it would have a material adverse
effect on the Owners and holders of the Securities.

         OIL POLLUTION ACT OF 1990

         OPA 90 imposes liability on responsible parties, as defined by OPA 90,
for clean-up expenses and damages caused by oil spills. Such responsible parties
could include owners, operators and demise charterers of vessels. OPA 90 applies
to all vessels that trade in the United States or its territories or possessions
or operate in United States waters, even if such vessels do not carry oil as
cargo, as is the case with the Vessels.

         Liability imposed under OPA 90 is joint and several for all spill
containment expenses, clean-up costs, and other damages arising from actual and
threatened oil spills from their vessels. Such a spill could include the
discharge of bunkers from the Vessels. Subject to statutory qualifications, a
sole fault third party may be also be a responsible party under OPA 90. For
example, a Vessel could cause another vessel to suffer a discharge of oil. Other
damages recoverable under OPA 90 include: (i) natural resource damages and the
costs of assessment thereof; (ii) real and personal property damage; (iii) net
loss of taxes, royalties, rent, fees, and other lost government revenues; (iv)
lost profits or impairment of earning capacity due to property or natural
resource damage; (v) net cost of public services necessitated by a spill
response, such as protection from fire, safety or health hazards; and (vi) loss
of subsistence use of natural resources.

         A responsible party's limit of liability under OPA 90 is the greater of
$1,200 per gross tonne of the discharging vessel or $10 million per vessel
(subject to possible adjustment for inflation); however, this limit would not
apply if the incident were proximately caused by violation of applicable United
States federal safety, construction or operating regulations or by the
responsible party's gross negligence or willful misconduct, or if the
responsible party fails or refuses to report an incident which the responsible
party knows or has reason to know of, or to provide all reasonable cooperation
and assistance requested by a responsible official in connection with oil
removal activities. OPA 90 does not by its terms impose liability on lenders or
the holders of mortgages on vessels; however, there is no specific exclusion for
such entities under OPA 90. In addition, if the Collateral Agent or any holder
of the Notes participates so substantially in the overall management of the
Vessels so as to be considered their "operator" or exercises remedies and
becomes an "owner" or "operator" or "demise charterer" of a Vessel following a
Mortgage Event of Default, such persons or entities may be subject to liability
under OPA 90. A catastrophic spill could exceed the liability limits of any
insurance coverage available, in which event there could be a material adverse
effect on the owner and the operator of the vessel involved in the spill.

         OPA 90, like CERCLA, requires owners and operators of all vessels,
whether or not such vessels carry oil as cargo, to establish and maintain with
the Coast Guard evidence of insurance or of qualification as a self-insurer or
other evidence of financial responsibility sufficient to meet their potential
strict liability limit under OPA 90. Owners or operators of tankers operating in
United States waters must file vessel response plans with the Coast Guard, and
their tankers must operate in compliance with their Coast Guard approved plans.
Such response plans must, among other things (i) identify and ensure, through
contract or other approved means, the availability of necessary private response
resources to respond to a "worst case" discharge; (ii) describe crew training
and drills; (iii) identify a qualified individual with full authority to
implement removal actions; and (iv) describe mitigation and response actions.
The Owners will ensure that the Vessels have response plans approved by the
Coast Guard.


                                      -64-
<PAGE>

         OPA 90 specifically permits individual states to impose their own
liability regimes with regard to oil pollution incidents occurring within their
boundaries, and many states have enacted legislation providing for unlimited
liability for oil spills. In some cases, states which have enacted such
legislation have not yet issued implementing regulations defining tanker owners'
responsibilities under these laws. Additionally, under OPA 90 the liability of
responsible parties, United States or foreign, with regard to oil pollution
damage in the United States is not preempted by any international convention.

         OPA 90 expressly provides that individual states are entitled to
enforce their own pollution liability laws, even if inconsistent with or
imposing greater liability than OPA 90. There is no uniform scheme among the
states. Some states have OPA 90-like schemes for limiting liability to various
amounts, other states rely on fault-based remedies under common law, while still
other states impose strict and unlimited liability on an owner or operator. In
addition, some states also have established their own requirements for financial
responsibility. Compliance with and violation of such state regulations, and the
liabilities imposed thereunder, may have a material adverse effect on the
business and the operations of the Owners and any charterer of the Vessels.

         INTERNATIONAL MARITIME ORGANIZATION

         The IMO, an agency organized in 1958 by the United Nations in which
over 100 national governments are members, provides international regulations
and practices affecting shipping and international trade and encourages the
adoption of standards of safety and navigation. During the last 35 years, the
IMO has initiated over 700 resolutions and 30 major conventions and protocols.
All IMO agreements must be ratified by the individual government constituents.

         In May 1996, the IMO adopted a draft International Convention on
Liability and Compensation for Damage in Connection with the Carriage of
Hazardous and Noxious Substances by Sea (the "HNS Convention"). The HNS
Convention is open for signature until October 1,
1997.
It is unknown at this time which countries, if any, will become signatories to
the HNS Convention. The HNS Convention establishes a uniform international legal
regime to ensure prompt and adequate compensation to victims of spills and
release of hazardous and noxious substances ("HNS") from vessels. HNS are
defined broadly by reference to various IMO codes and lists and include
approximately 6,000 bulk and packaged substances.

         Damages recoverable under the HNS Convention include personal injury
and death, property damage outside the ship, environmental damage, and
preventive measures. The HNS Convention excludes damage for oil that is covered
by the CLC, as defined below. There are two tiers of liability under the HNS
Convention. Tier one is strict shipowner liability that must be guaranteed by
compulsory insurance or some other financial guarantee. Limits of liability
under the first tier are based on tonnage: for (i) vessels less than 2,000 gross
tonnes, the limit of liability is 10 million Special Drawing Rights ("SDRs"). An
SDR is defined by the International Monetary Fund on the basis of a basket of
currencies. The exchange rate in effect on June 30, 1997 for the dollar
equivalent of the SDR was approximately 1.39; (ii) vessels greater than 2,000
gross tonnes but less than 50,000 gross tonnes have an additional limit of 1,500
SDRs per tonne above 2,000; and (iii) vessels with a gross tonnage in excess of
50,000 will have a limit of an additional 360 SDRs per tonne up to a maximum of
100 million SDRs (E.G., at $1.39 per SDR, a 100,000 gross tonne vessel would
have


                                      -65-
<PAGE>

a limit of liability under the HNS Convention of approximately $139,000,000).
The second tier of liability under the HNS Convention is an international fund
(the "HNS Fund"), which will pay compensation for damages that exceed the vessel
owner's liability limit or if the vessel owner is not liable or is otherwise
unable to meet its first tier liability obligations. Total liability under the
first and second tiers is limited to 250 million SDRs. A vessel owner loses its
right to limit liability under the HNS Convention if it is proved that the
damage resulted from the personal act or omission of the owner, committed with
the intent to cause such damage, or recklessly and with knowledge that such
damage would probably result.

         The HNS Fund will be composed of several accounts. There will be a
separate account for (i) liquified natural gas ("LNG"); (ii) LPG; and (iii) oil.
These industries will contribute to the HNS Fund by receivers and importers of
HNS in a contracting state (with the exception of the LNG account). In the case
of LNG industry, the cargo titleholder will pay contributions to the LNG account
immediately prior to discharge in a contracting state. Collections and payments
from contributors will be managed by the HNS Fund, and contributors will be
invoiced annually. The amount of the levy will be determined primarily by the
claims submitted to the HNS Fund the preceding year and the volume of HNS the
contributor imported. Initial contributions will also be required to capitalize
the HNS Fund and cover administrative costs. In addition to the special HNS Fund
accounts, there will be a general account to provide compensation for damage
from any HNS not falling within the HNS separate accounts.

         Outside the United States, many countries have ratified and follow the
liability scheme adopted by the IMO and set out in the International Convention
on Civil Liability for Oil Pollution Damage of 1969 ("CLC"), as amended by the
1992 Protocol, which entered into force May 30, 1996. Under the CLC, an oil
tanker's registered owner is strictly liable for pollution damage caused on the
territorial waters of a contracting state by a discharge of oil, subject to
certain defenses and limits. The current limit for a ship not exceeding 5,000
gross tonnes is 3.0 million SDRs and, for each additional tonne on a larger
vessel, an additional 420 SDRs, up to a maximum of 59.7 million SDRs (E.G., at
$1.39 per SDR, the maximum liability is approximately $83 million). Vessels
trading to contracting states must establish evidence of insurance covering the
limit of liability of the owner. In jurisdictions where the CLC has not been
adopted, various legislative schemes or common law govern, and liability is
imposed either on the basis of fault or in a manner similar to the CLC. On March
6, 1992, the IMO adopted regulations which set forth new and upgraded
requirements for pollution prevention for tankers. These regulations went into
effect on July 6, 1995. Each Vessel will be required to comply with such IMO
regulations.

         The IMO continues to review and introduce new regulations on a regular
basis. It is impossible to predict what additional regulations, if any, may be
passed by the IMO, whether those regulations will be adopted by member countries
and what effect, if any, such regulations might have
on the operation of the Vessels.

         security is defined by Rule 13d-3 under the Exchange Act as consisting
         of sole or shared voting power (including the power to vote or direct
         the vote) and/or sole or shared investment power (including the power
         to dispose or direct the disposition) with respect to the security
         through any contract, arrangement, understanding, relationship, or
         otherwise, including a right to acquire such power(s) during the next
         60 days. Unless otherwise noted, beneficial ownership consists of sole
         ownership, voting and investment power with respect to all Holdings
         Common Stock (being ordinary shares) shown as beneficially owned by
         them.

Common Stock in exchange for management services to be performed by the Manager
as agent of CGTC prior to the Delivery Date of each Vessel pursuant to the
Management Agreement. The services to be performed by the Manager as agent of
CGTC were treated by Holdings as an equity contribution with a cost basis of
$3.0 million, and will be recognized for financial reporting purposes as such

                                      -71-
<PAGE>

and for services contributed during the first six years of operation under the
Technical Management Agreement. The supervision services to be performed by
GEBAB was accounted for by Holdings as an equity contribution with a cost basis
of $4.0 million. For financial reporting purposes, $1.0 million of this amount
was recognized on the Original Closing Date reflecting services provided prior
to such date, and the remaining $3.0 million was recognized as future services

Management Agreement.

         (d) Xenon Shipping was issued 200,000 shares of Holdings Common Stock
in exchange for a cash contribution in the amount of $9.3 million, which

         (e) TGE was issued 200,000 shares of Holdings Common Stock in exchange

million in cash for deposit by the Collateral Agent into the Pre-Funding Account
and directed Generale to deliver the TGE Performance Bond to the Collateral

         The value assigned to the components of the Equity Financing may not
accurately reflect the true value thereof for the purpose of valuing Holdings.

         The Designated Owners (as defined) have agreed not to dispose of their
respective stock in Holdings if any Notes are outstanding; PROVIDED that such
Designated Owners may sell a portion of their respective stock, if after such
sale, the stock held by such Designated Owners, either directly or indirectly,
represents more than 50% of the total voting power of the Voting Stock (as
defined) of Holdings and more than 50% of the equity interests in Holdings.

STOCKHOLDERS AGREEMENT

         Holdings and its stockholders of record are parties to a Stockholders
Agreement, dated as of August 1, 1997, which contains various restrictions on
the transfer of stock owned by the stockholders. CGTC has a right of first
refusal to purchase any shares which one or more of the other stockholders
propose to sell. The agreement provides that certain stockholders continue to
hold a specified minimum number of shares for a certain period of time. Except
to an affiliate of TGE, TGE has agreed not to dispose of its stock in Holdings
prior to the expiration of the warranty period of the last Vessel to be
delivered. The stockholders have the right, in the event CGTC sells all or any
portion of its stock, to require CGTC to purchase an amount of stock from each
such other stockholder which is equal to that fraction (expressed as a
percentage, the numerator of which is the number of shares owned by such other
stockholder and the denominator of which is the aggregate number of shares owned
by all shareholders) of the shares of stock owned by such other stockholder,
times the number of shares of stock sold by CGTC. The agreement contains
provisions which


                                      -72-
<PAGE>

prevent the Designated Owners from reducing their aggregate interest in Holdings
to less than a majority interest.

Technical Supervision Agreement, Technical Management Agreement and Commercial
Management Agreement. The Manager will receive a fee of $30,000 per annum for
each Vessel prior to the Delivery Date for such Vessel and $120,000 per Vessel
per annum from and after the Delivery Date for such Vessel. Prior to the
Delivery Date for the first Vessel, the Manager will be responsible for the
payment of the fees and expenses of the Trustees and the Collateral Agent. See
"BUSINESS--MARKETING AND COMMERCIAL MANAGEMENT." In addition, the Manager, as

Vessels' construction on behalf of the Owners. The cost of these services, which
will be $4.0 million, will be contributed to Holdings as and when performed.

UK LEASE

         As a component of a UK Lease (as defined), the Owners (or lessees under
full payout leases) may enter into either hire purchase agreements (each, an
"HPA") or conditional sale contracts (each, a "CSC") with UK Lessors (as
defined) under which such UK Lessors will initially pay an amount equal to
substantially all of the Purchase Price for each of the related Vessels and
which grants such UK Lessors a right of possession in respect of such Vessels.
Each HPA or CSC will provide that the related Owner will (unless the related UK
Lessor fails to exercise its option in the case of an HPA or otherwise elects in
the case of CSC) pass title to the related Vessel to the related UK Lessor after
the passage of an agreed upon period of time after the delivery of such Vessel
or following any early termination of the related Bareboat Lease (as defined) at
which time the nominal remainder of the Purchase Price for such Vessel will be
paid. Other than as described above, a UK Lessor will have no right to acquire
title to the related Vessel.

         Each UK Lessor will be required to acknowledge the rights of the
Collateral Agent to the related Vessel and any income and proceeds therefrom as
provided in the related Mortgage and in the Intercreditor Agreement or otherwise
agree to respect such rights (pursuant to an inter-creditor or co-ordination
agreement). The Owners and the Collateral Agent will acknowledge to the related
UK Lessors that they will (i) not vary provisions of the related Mortgages
relating to certain rights as to the disposition of insurance proceeds and (ii)
give such UK Lessors notice of any defaults under such Mortgages and the right
to cure such defaults, PROVIDED that such rights of cure will not be available
if the related Owners are subject to bankruptcy or insolvency proceedings and
will be available for only a single period of 90 days.

         As a further component of a UK Lease, each UK Lessor will in turn lease
the related Vessel back to the related Owner under a separate, full payout
bareboat lease (each, a "Bareboat Lease") for such Vessel. It is anticipated
that each Owner will pay to a subsidiary of another major UK Bank (each, a
"Defeasance Bank") a sum of money, and that such Defeasance Bank will, in
consideration of such payment, assume, up to certain limits of liability, the
payment obligations of such Owner under the related Bareboat Lease. To the
extent such payment obligations under a Bareboat Lease are assumed by such
Defeasance Bank, the related Owner will be released from those obligations;
PROVIDED, HOWEVER, that each Owner will remain liable under its Bareboat Lease
for payment obligations in excess of the obligations thus defeased.

         It is anticipated that the Vessels will be chartered by the Owners to a
shipping company or a subsidiary of Holdings pursuant to either bareboat or time
charters. It is a requirement of the UK tax legislation that while the Vessels
are leased by UK Lessors such leasing arrangements must continue for a period of
10 years and each lessee must be a company which (i) is liable for UK corporate
tax in respect of its profits from the related Vessel and (ii) uses such Vessel
for the purposes of that company's non-leasing trade or charters such Vessel in
such manner as to satisfy the UK legislation relating to the availability of
depreciation allowances for the UK Lessors.

         As a precondition to any Owner entering into a UK Lease, any nationally
recognized statistical rating agency then rating the Notes (the "Rating
Agencies"), must confirm to the Trustees in writing that entering into such UK
Lease will not result in a ratings decline with respect to the
Notes.

         In addition, at any time and from time to time prior to June 30, 2000,
the Issuer may redeem in the aggregate up to 35% of the original principal
amount of each series of Notes, on a PRO RATA basis, with the proceeds of one or
more Public Equity Offerings (with the cash proceeds thereof to the extent
actually contributed to the Issuer) following which there exists a Public
Market, at a redemption price (expressed as a percentage of principal amount) of
110.5% (in the case of the First Priority Exchange Notes) and 112% (in the case
of the Second Priority Exchange Notes), plus in each case accrued interest to
the redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant Interest Payment Date);
PROVIDED, HOWEVER, that at least $100 million aggregate principal amount of
First Priority Exchange Notes and the untendered Existing First Priority Notes,
if any, and $45 million aggregate principal amount of Second Priority Exchange
Notes and the untendered Existing Second Priority Notes, if any, must remain
outstanding after each such redemption.

         Other than as set forth in the previous paragraph, the First Priority
Indenture will prohibit the Issuer from redeeming at the option of the Issuer
any Second Priority Notes while the First Priority
Notes are outstanding.

         MANDATORY REDEMPTION UPON THE OCCURRENCE OF CERTAIN EVENTS

         In the event an Owner elects to terminate its Building Contract because
of a material breach thereof by the Builders (including a failure to pay
liquidated damages for any delay in the delivery of the related Vessel), the
Exchange Notes of each series will be subject to mandatory redemption in part,
on a PRO RATA basis, in an aggregate principal amount equal to the Allocated
Principal Amount of the Notes for such Vessel and for each other Vessel that has
not been accepted by its related Owner as of the date of such termination, at a
redemption price equal to 100% of the principal amount thereof, plus accrued and
unpaid interest to and including the date of redemption (subject to the right of
a Holder of record on the relevant record date to receive interest due on the
relevant Interest Payment Date), upon the earlier to occur of (a) the receipt of
the Refund Amount with respect to the related Building Contract(s) and (b) 60
days after the termination of such Building Contract(s) by the related Owner(s).

         If a Vessel is subject to Total Loss (as defined), the Exchange Notes
of each series will be subject to mandatory redemption in part, on a PRO RATA
basis, in an aggregate principal amount equal to the Allocated Principal Amount
of the Notes for such Vessel, at a redemption price equal to 101% of the
principal amount thereof, plus accrued and unpaid interest to the date of
redemption (subject to the right of a Holder of record on the relevant record
date to receive interest due on the relevant Interest Payment Date), upon the
earlier to occur of (a) the receipt of the Insurance Proceeds (as defined) with
respect to such Total Loss and (b) 60 days after such Total Loss was deemed to
have occurred.

         SELECTION AND NOTICE

         Unless otherwise expressly stated, if the Exchange Notes are to be
redeemed in part, the selection of the Exchange Notes to be redeemed will be
made by the applicable Trustee on a PRO RATA basis, by lot or by such other
method as such Trustee in its sole discretion shall deem to be fair and
appropriate; PROVIDED that, in all cases the Exchange Notes may be redeemed in
multiples of $1,000 only, and subject always to the provisions described above.
Any notice of redemption will specify (i) the Exchange Notes subject to
redemption; (ii) whether the Exchange Notes are to be redeemed in whole or in
part, and the aggregate principal amount of the Exchange Notes to be redeemed;
and (iii) the date of such redemption. Once an Exchange Note or portion thereof
has been redeemed, interest will cease to accrue thereon as of the redemption
date.

ADDITIONAL AMOUNTS

         All payments of, or in respect of, principal of and any premium and
interest on the Exchange Notes, and all payments pursuant to the Guarantees,
shall be made without withholding or deduction for, or on account of, any
present or future taxes, duties, assessments or governmental charges of whatever
nature (or interest on any taxes, duties, assessments or other governmental
charges of whatever nature) imposed or levied by or on behalf of, or within, the
Isle of Man (or the jurisdiction of incorporation of any successor of the Issuer
or any of the Owners) or any political subdivision or taxing authority thereof
or therein ("Taxes"), unless such Taxes are required by the Isle of Man or the
jurisdiction of incorporation of any successor to the Issuer or any of the
Owners (each a


                                      -79-
<PAGE>

"Successor Jurisdiction"), as the case may be, or any such authority to be
withheld or deducted. In that event, the Issuer, the relevant Owners or any
successor, as the case may be, will pay such additional amounts of, or in
respect of, principal and any premium and interest or with respect to payments
pursuant to the Guarantees ("Additional Amounts") as may be necessary so that
the net amount received by each Holder (including Additional Amounts) after such
withholding or deduction will not be less than the amounts that the Holder would
have received if such Taxes had not been withheld or deducted, except that no
Additional Amounts shall be so payable for or on account of:

         (1) Taxes that would not have been imposed but for

                  (a) the existence of any present or former connection between
         such Holder (or between a fiduciary, settlor, beneficiary, member or
         shareholder of, or possessor of a power over, such Holder, if such
         Holder is an estate, trust, partnership or corporation) and the Isle of
         Man or any Successor Jurisdiction (including any territory or political
         subdivision of the foregoing), as the case may be, including such
         Holder (or such fiduciary, settlor, beneficiary, member, shareholder or
         possessor) being or having been a national, domiciliary or resident of
         or treated as a resident thereof or being or having been present or
         engaged in a trade or business therein or having or having had a
         permanent establishment therein;

                  (b) the presentation of such Exchange Note for payment in the
         Isle of Man or any Successor Jurisdiction, as the case may be, or any
         of their respective territories or political subdivisions, unless such
         Exchange Note could not have been presented for payment elsewhere; or

                  (c) the presentation of such Exchange Note more than 30 days
         after the date on which the payment in respect of such Exchange Note
         became due and payable or provided for, whichever is later, except to
         the extent that the Holder would have been entitled to such Additional
         Amounts if it had presented such Exchange Note for payment on any day
         within such period of 30 days;

         (2) any estate, inheritance, gift, sale, transfer, personal property or
similar tax, assessment or other governmental charge;

         (3) any tax, assessment or other governmental charge that is imposed or
withheld by reason of the failure of the Holder or beneficial owner of an
Exchange Note to comply with a request of the Issuer or any of the Owners, as
the case may be, addressed to the Holder (a) to provide reasonable information
concerning the nationality, residence or identity of the Holder or such
beneficial owner or (b) to make any reasonable declaration or other similar
claim or satisfy any reasonable information or reporting requirement, which, in
the case of (a) or (b), is required or imposed by a statute, treaty, regulation
or administrative practice of the taxing jurisdiction as a precondition to
exemption from all or part of such tax, assessment or governmental charge; or

         (4) any combination of items (1), (2) and (3);


                                      -80-
<PAGE>

nor shall Additional Amounts be paid with respect to any payment of the
principal of or any premium or interest on any such Exchange Note, or payment
pursuant to the Guarantees, to any Holder (including a fiduciary or partnership)
to the extent that the beneficial owner would not have been entitled to such
Additional Amounts had it been the Holder of the Exchange Note. The Issuer or
the relevant Owners, as the case may be, will also (i) make such withholding or
deduction and (ii) remit the full amount deducted or withheld to the relevant
authority in accordance with applicable law. The Issuer or the relevant Owners,
as the case may be, will furnish to Holders of Exchange Notes that are
outstanding on the date of the withholding or deduction for or on account of
Taxes, within 30 days after the date of the payment of any Taxes due pursuant to
applicable law, certified copies of tax receipts evidencing such payment by the
Issuer or the relevant Owners, as the case may be.

         Whenever there is mentioned, in any context, the payment of the
principal of or any premium or interest on, or in respect of, any Exchange Note,
any payment pursuant to the Guarantees or the net proceeds received from the
Issuer or the Owners on the sale or exchange of any Exchange Note, such mention
shall be deemed to include mention of the payment of Additional Amounts provided
for in the Indentures to the extent that, in such context, Additional Amounts
are, were or would be payable in respect thereof pursuant to the Indentures.

         The Issuer or the relevant Owners, as the case may be, will pay any
present or future stamp, court or documentary taxes or any other excise or
property taxes, charges or similar levies that arise in any jurisdiction from
the execution, delivery, enforcement or registration of the Exchange Notes or
the Guarantees or any other document or instrument in relation thereto, or the
receipt of any payments with respect to the Exchange Notes or Guarantees,
excluding such taxes, charges or similar levies imposed by any jurisdiction
outside of the Isle of Man, any Successor Jurisdiction or any jurisdiction in
which a paying agent is located (except those resulting from or required to be
paid in connection with, the enforcement of the Exchange Notes or the Guarantees
or any other such document or instrument following the occurrence of any Event
of Default with respect to the Exchange Notes), and has agreed to indemnify the
Holders for any such taxes paid by such Holders.

TAX REDEMPTION

         If, as a result of any change in or any amendment to the laws,
regulations or published tax rulings of the Isle of Man or any Successor
Jurisdiction, or of any political subdivision or taxing authority thereof or
therein, or any change in the official administration, application or
interpretation of such laws, regulations or published tax rulings either
generally or in relation to any particular Exchange Notes, which change or
amendment becomes effective on or after the Original Closing Date or which
change in official administration, application or interpretation shall not have
been available to the public prior to the Original Closing Date and is notified
to the Issuer or the relevant Owners, as the case may be, on or after the
Original Closing Date, it is determined by the Issuer or the relevant Owners, as
the case may be, that the Issuer or the relevant Owners, as the case may be,
would be required to pay, or that the Issuer or the relevant Owners, as the case
may be, would be substantially likely to be required to pay, any Additional
Amounts (as defined in "Additional Amounts" above) pursuant to the Indentures or
the terms of any Exchange Note in respect of interest on the next succeeding
Interest Payment Date (assuming, in the case of the Owners, that a payment in
respect of such interest were required to be made by the relevant Owners under
the Guarantees


                                      -81-
<PAGE>

on such Interest Payment Date), and that such obligation cannot be avoided by
the Issuer or the relevant Owners taking reasonable measures available to it,
the Issuer may, at its option, redeem all (but not less than all) the Exchange
Notes in respect of which such Additional Amounts would be so payable at any
time, upon not less than 30 nor more than 60 days' written notice as provided in
the Indentures, at a redemption price equal to 100% of the principal amount
thereof plus accrued interest to the date fixed for redemption (subject to the
right of a Holder of record on the relevant record date to receive interest due
on the relevant Interest Payment Date); PROVIDED, HOWEVER, that (a) no such
notice of redemption may be given earlier than 60 days prior to the earliest
date on which the Issuer or the relevant Owners, as the case may be, would be
obligated, or is substantially likely to be obligated, to pay such Additional
Amounts were a payment in respect of the Exchange Notes or the Guarantees, as
the case may be, then due, and (b) at the time any such redemption notice is
given, such obligation, or substantial likelihood, to pay such Additional
Amounts must remain in effect.

GUARANTEES

         Payment of the principal of, and premium, if any, and interest on the
Exchange Notes, payment to the Letter of Credit Issuer of the Issuer's
obligations under the Letter of Credit Reimbursement Agreement, and the Issuer's
obligations for payment of all sums of money payable under the Security
Agreements and performance of all other obligations contained in the Indentures
and the Security Agreements (collectively, the "Obligations") is guaranteed
(each, a "Guarantee," and, collectively, the "Guarantees"), jointly and
severally, on a secured basis by each of the Owners. Each Guarantee is
irrevocable and unconditional but limited to an amount not to exceed the maximum
amount that can be guaranteed by the applicable Owner without rendering such
Guarantee voidable under applicable laws relating to fraudulent conveyance or
fraudulent transfer or similar laws affecting the rights of creditors generally.
If a Guarantee were to be rendered voidable, it could be subordinated by a court
to all other indebtedness (including guarantees and other contingent
liabilities) of the applicable Owner, and, depending on the amount of such
indebtedness, an Owner's liability on its Guarantee could be reduced to zero.
See "RISK FACTORS--RANKING OF THE EXCHANGE NOTES AND GUARANTEES" and
"--FRAUDULENT CONVEYANCE STATUTES."

SECURITY

         Pursuant to the Intercreditor Agreement, the Collateral Agent is
holding and will hold the Collateral (defined below) in trust for the benefit of
the Holders of the Exchange Notes, as well as for the benefit of the Letter of
Credit Issuer and the Trustees. In addition, pursuant to the Intercreditor
Agreement, the Collateral Agent has or will establish the Trust Accounts for the
deposit and application of funds, as described below under "--TRUST ACCOUNTS"
and "--PRIORITIES OF PAYMENT."

         On the Original Closing Date, (a) to secure the Issuer's obligations
under the Indentures, the Security Agreements, the Letter of Credit
Reimbursement Agreement and in respect of the Notes, Holdings pledged to the
Collateral Agent, for the benefit of the Holders of the Exchange Notes, the
Letter of Credit Issuer and the Trustees, all the Capital Stock of the Issuer
(the "Holdings Pledge") and the Issuer pledged to the Collateral Agent, for the
benefit of the Holders of the Exchange Notes, the Letter of Credit Issuer and
the Trustees, all the Capital Stock of the Owners and the Intercompany


                                      -82-
<PAGE>

Note, and granted a security interest in all of its rights, titles and interests
in the Trust Accounts and all cash, securities, instruments or other property
credited thereto or deposited therein, and (b) to secure its obligations under
its Guarantee and under the Security Agreements, each Owner granted to the
Collateral Agent, for the benefit of the Holders of the Exchange Notes, the
Letter of Credit Issuer and the Trustees, a security interest in all its right,
title and interest in the following assets and documents: (i) the Building
Contract for the applicable Vessel; (ii) the Technical Supervision Agreement;
(iii) the Building Contract Guarantee for such Vessel and the Performance Bonds;
(iv) the Technical Management Agreement; (v) the Commercial Management
Agreement; (vi) the Trust Accounts and all cash, securities, instruments or
other property credited thereto or deposited therein; (vii) all monies and
securities, including Temporary Cash Investments, paid to or deposited with, or
required to be paid to or deposited with, the Collateral Agent by or for the
account of the Issuer or such Owner, or otherwise pursuant to the terms of any
Security Agreement; (viii) the Management Agreement; (ix) all rights of such
Owner to receive payments of any kind, to execute any election or option or to
give or receive any notice, consent, waiver or approval under or in respect of
any of the foregoing documents or instruments; (x) any and all assets of such
Owner whether now owned or hereafter acquired; and (xi) all income, payments,
proceeds, rights and claims, resulting from or arising out of the foregoing. The
foregoing collateral pledged by Holdings, the Issuer and the Owners is herein
collectively referred to as the "Original Closing Date Collateral."

         On the Delivery Date of each Vessel, the related Owner will grant to
the Collateral Agent, for the benefit of the Holders of the Exchange Notes, the
Letters of Credit Issuer and the Trustees, a security interest in all of such
Owner's right, title and interest in the following assets and documents acquired
by such Owner after the Original Closing Date (the "Delivery Date Collateral"
and, together with the Original Closing Date Collateral, the "Collateral"): (i)
such Vessel in accordance with the terms and conditions of the related Mortgage;
(ii) all earnings and insurances in respect of such Vessel; (iii) all the
charterhire, tolls, rents, issues, profits, products, revenues and other income
(including insurance and warranty proceeds) from the property subject to, or
required to be subject to, the Lien under the Mortgage, and all the estate,
right, title and interest of such Owner in and to the same and every part of
said property; (iv) all requisition proceeds and Insurance Proceeds with respect
to such Vessel or any part thereof (to the extent of the Collateral Agent's
interest therein as mortgagee of such Vessel pursuant to the related Mortgage);
and (v) all income, payments, proceeds, rights and claims, resulting from or
arising out of the foregoing.

         The Holders of the Exchange Notes, the Letter of Credit Issuer and the
Trustees will have an equal and ratable interest in the Collateral, subject to
the priority of payment described below under "--APPLICATION OF PROCEEDS
FOLLOWING AN EVENT OF DEFAULT." If Insurance Proceeds are payable in respect of
a Total Loss of any Vessel, the Trustees will instruct the Collateral Agent to
release the Lien on such Vessel and the related Collateral and the related Owner
from all of its obligations under its Guarantee upon receipt by the Collateral
Agent of the Total Loss Payment with respect to such Vessel. In connection with
the termination by an Owner of the related Building Contract because of a
material breach thereof by the Builder and the termination of the Building
Contracts for each other Vessel that has not been accepted by its Owner as of
the date of such termination, the Trustees will instruct the Collateral Agent to
release the Liens on such Building Contracts and the related Collateral and the
related Owners from their obligations under their Guarantees upon receipt by the
Collateral Agent of the Rescission Amounts for such Vessels.

INTEREST DRAWS ON THE LETTER OF CREDIT

         On the Original Closing Date, the Letter of Credit was issued by the
Letter of Credit Issuer in favor of the Collateral Agent for the benefit of the
Holders of the Exchange Notes and the Trustees. The Collateral Agent is not and
will not be eligible by the terms of the Letter of Credit to make an Interest
Draw (as defined below) thereunder until after the Delivery Date of the first
Vessel. Three Business Days prior to each Interest Payment Date thereafter, the
Collateral Agent shall determine if a Note Interest Shortfall exists. If a Note
Interest Shortfall exists, no later than the day which is two Business Days
prior to such Interest Payment Date, the Collateral Agent shall make a draw
(each, an "Interest Draw") on the Letter of Credit in a Draw Amount (as defined)
equal to the lesser of (a) the Note Interest Shortfall (less any portion of such
Note Interest Shortfall attributable to interest payable pursuant to a
Registration Default) and (b) the Maximum Amount Available under the Letter of
Credit. No later than the Business Day prior to such Interest Payment Date, the
Letter of Credit Issuer shall remit such Draw Amount to the Collateral Agent and
the Collateral Agent shall deposit such amount into the Letter of Credit
Account.

         Under the terms of the Letter of Credit Reimbursement Agreement and the
Intercreditor Agreement, the Collateral Agent is not and will not be permitted
to make an Interest Draw to pay interest on the Second Priority Exchange Notes
until and unless the Issuer shall have, prior to or on the date of such Interest
Draw, issued additional Second Priority Exchange Notes in an aggregate principal
amount of $20.9 million to cover previous or concurrent shortfalls in cash
available in the Revenue Account to pay interest on the Second Priority Exchange
Notes. On the first Business Day of each calendar month, (i) subject to the
prior distribution of any required (a) Monthly Operating Deposit and (b)
Manager's Fee (if such date shall also be a Management Fee Payment Date (as
defined)), cash available for distribution in the Revenue Account on such date
will be applied to the payment of unpaid fees in respect of the Letter of Credit
and all accrued and unpaid interest on all outstanding Draws under the Letter of
Credit and to the repayment, to the extent of funds remaining therein, of all
Working Capital Draws outstanding on such date and then all Interest Draws
outstanding; and (ii) if such date shall also be an Interest Payment Date after
the Delivery Date of the first Vessel, the repayment of all Draws outstanding on
such date shall be subject to the prior distribution of any required fees and
expenses payable to the Trustees and the Collateral Agent in respect of the
Indentures and the Intercreditor Agreement. See "--PRIORITIES OF
PAYMENT--REVENUE ACCOUNT."

RANKING

         The First Priority Exchange Notes and the untendered Existing First
Priority Notes, if any, and the Second Priority Exchange Notes and the
untendered Existing Second Priority Notes, if any, will be secured obligations
of the Issuer. With respect to claims against the Collateral securing the
Exchange Notes, the Holders of the Exchange Notes will have a claim thereto
which is subordinate in right of payment to any claim held by the Letter of
Credit Issuer with respect to any unreimbursed Draws under the Letter of Credit.
The priority of payment of the principal of, premium (if any) and interest on
the Exchange Notes is as described under "Description of the Exchange
Notes--Priority of Payment--Revenue Account,"-- "Priority of Payment--
Termination Account" and "-- Application of Proceeds Following an Event of
Default." Neither the Issuer nor


                                      -84-

the Owners are permitted by the Indentures to incur any additional Indebtedness,
with certain limited exceptions. See "Description of the Exchange
Notes--Ranking."

Date thereafter, the Issuer will be required, to the extent of Available Cash,
to make an Available Cash Offer to each Holder of the Second Priority Exchange

"--SOURCE OF FUNDS TO PURCHASE NOTES"), at a price equal to 101% of the
outstanding principal amount of such Exchange Notes, plus accrued and unpaid
interest to the date of purchase (the "Change of Control Payment"); PROVIDED,

FURTHER, that the Issuer shall purchase any and all First Priority Exchange
Notes validly tendered pursuant to a Change of Control Offer prior to purchasing
any Second Priority Exchange Notes validly tendered pursuant to such Change of
Control Offer.

         A "CHANGE OF CONTROL" is defined to mean the occurrence of any of the
following events:

                  (i) prior to the first public offering of common stock of
         Holdings, the Permitted Holders cease to be the "beneficial owner" (as
         defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or
         indirectly, of a majority in the aggregate of the total voting power of
         the Voting Stock of the Issuer, whether as a result of issuance of
         securities of Holdings or the Issuer, any merger, consolidation,
         liquidation or dissolution of Holdings or the Issuer, any direct or
         indirect transfer of securities by Holdings or otherwise (for purposes
         of this clause (i) and clause (ii) below, the Permitted Holders shall
         be deemed to beneficially own any Voting Stock of a corporation (the
         "specified corporation") held by any other corporation (the "parent
         corporation") so long as the Permitted Holders beneficially own (as so
         defined), directly or indirectly, in the aggregate a majority of the
         voting power of the Voting Stock of the parent corporation);

                  (ii) any "person" (as such term is used in Sections 13(d) and
         14(d) of the Exchange Act), other than one or more Permitted Holders,
         is or becomes the beneficial owner (as defined in clause (i) above,
         except that for purposes of this clause (ii) such person shall be
         deemed to have "beneficial ownership" of all shares that any such
         person has the right to acquire, whether such right is exercisable
         immediately or only after the passage of time), directly or indirectly,
         of more than 35% of the total voting power of the Voting Stock of the
         Issuer; PROVIDED, HOWEVER, that the Permitted Holders beneficially own
         (as defined in clause (i) above), directly or indirectly, in the
         aggregate a lesser percentage of the total voting power of the Voting
         Stock of the Issuer than such other person and do not have the right or
         ability by voting power, contract or otherwise to elect or designate
         for election a majority of the Board of Directors (for the purposes of
         this clause (ii), such other person shall be deemed to beneficially own

         in this clause (ii)), directly or indirectly, of more than 35% of the
         voting power of the Voting Stock of such parent corporation and the
         Permitted Holders beneficially own (as defined in clause (i) above),
         directly or indirectly, in the aggregate a lesser percentage of the
         voting power of the Voting Stock of such parent corporation and do not
         have the right or ability by voting power, contract or otherwise to
         elect or designate for election a majority of the board of directors of
         such parent corporation);

                  (iii) during any period of two consecutive years, individuals
         who at the beginning of such period constituted the board of directors
         of Holdings or the Issuer (together with any new directors whose
         election by such board of directors or whose nomination for election by
         the shareholders of Holdings or the Issuer, respectively, was approved
         by a vote of 662/3% of the directors of Holdings or the Issuer, as the
         case may be, then still in office who were either directors at the
         beginning of such period or whose election or nomination for election
         was previously so approved) cease for any reason to constitute a
         majority of the board of directors of Holdings or the Issuer,
         respectively, then in office;

                  (iv) either CGTC or GEBAB ceases to be a shareholder of

                  (v) prior to the expiration of the warranty period of the last
         Vessel, TGE (including its Affiliates) disposes of any of its shares in
         Holdings other than to an Affiliate of TGE.

         PROCEDURE FOR PURCHASE OF NOTES. On the next succeeding Business Day
after the Available Cash Determination Date with respect to an Available Cash
Offer and within 30 days after the occurrence of a Change of Control, the Issuer
will be required to provide, by mail (first class, prepaid) written notice to
the Trustees and each Holder stating that: (i) Available Cash is expected to be
available on the next succeeding Available Cash Payment Date or a Change of
Control has occurred, as applicable; (ii) an Available Cash Offer is being made
and Exchange Notes of the applicable series having an aggregate principal amount
equal to Available Cash divided by 1.02 (the "Maximum Principal Amount") will be
accepted for payment (provided that no Second Priority Exchange Note or
untendered Existing Secured Priority Note, if any, will be accepted for payment
unless and until all First Priority Exchange Notes and untendered Existing First
Priority Notes, if any, have been repaid in full) or a Change of Control Offer
is being made and all Exchange Notes validly tendered will be accepted for
payment, as applicable; (iii) the purchase price and date of purchase (which
shall be the Available Cash Payment Date, in the case of an Available Cash
Offer, or which shall be a Business Day not less than 30 days nor more than 60
days from the date on which such Change of Control notice is mailed in the case
of a Change of Control Offer); (iv) any Exchange Note not tendered will continue
to accrue interest pursuant to its terms; (v) any Exchange Note accepted for
payment pursuant to the Available Cash Offer or the Change of Control Offer, as
applicable, shall cease to accrue interest on and after the purchase payment
date therefor (in the case of a Change of Control Offer, the "Change of Control
Payment Date" and, together with the Available Cash Payment Date, the "Purchase
Payment Date"), unless the Issuer defaults on such payment; (vi) Holders of
Exchange Notes electing to have any Exchange Note or portion thereof purchased
pursuant to an Available Cash Offer or Change of Control Offer will be required,
prior to the close of business on the Business Day immediately preceding the
applicable Purchase Payment Date, to surrender such Exchange Note to the
applicable Trustee at the address specified in the notice, together with a
completed form entitled "Option of the Holder to Elect Purchase" on the reverse
side of such Note; (vii) Holders of Exchange Notes will be entitled to withdraw
their election if the applicable Trustee receives, not later than the close of
business on the third Business Day immediately preceding the applicable Purchase
Payment Date, a telegraph, facsimile transmission or letter setting forth the
name of such Holder, the principal amount of Exchange Notes delivered for
purchase, and a statement that such Holder is withdrawing his election to have
such Exchange Notes purchased; and (viii) Holders whose Exchange Notes are being
purchased in part will receive new Exchange Notes of the same series and in
principal amount equal to the unpurchased portion of the Exchange Notes
surrendered; PROVIDED, HOWEVER, that each Exchange Note purchased and each new
Exchange Note issued shall be in a principal amount of $1,000 or integral
multiples thereof.

         On the applicable Purchase Payment Date, the Issuer will be required
to: (i) accept for payment all Exchange Notes or portions thereof tendered
pursuant to the Available Cash Offer (provided that no Second Priority Exchange
Note will be accepted for payment unless and until all First Priority Exchange
Notes and untendered Existing First Priority Notes, if any, have been repaid in
full) or Change of Control Offer (provided that the Issuer shall purchase any
and all First Priority Exchange Notes and untendered Existing First Priority
Notes, if any, validly tendered pursuant to a Change of Control Offer prior to
purchasing any Second Priority Exchange Notes and untendered


                                      -87-
<PAGE>

Existing Second Priority Notes, if any, validly tendered pursuant to such Change
of Control Offer), as applicable; (ii) deposit with the applicable Trustee funds
sufficient to pay the purchase price of all Exchange Notes of the applicable
series or portions thereof so accepted; and (iii) deliver or cause to be
delivered to the applicable Trustee, all Exchange Notes or portions thereof so
accepted together with an officers' certificate specifying the Exchange Notes or
portions thereof accepted for payment. The applicable Trustee shall promptly
mail, to the Holders of Exchange Notes so accepted, payment in an amount equal
to the purchase price, and the applicable Trustee shall promptly authenticate
and mail to such Holders a new Exchange Note of such series equal in principal
amount to any unpurchased portion of the Exchange Notes of such series
surrendered; PROVIDED, HOWEVER, that each Exchange Note purchased and each new
Exchange Note issued shall be in a principal amount of $1,000 or integral
multiples thereof; PROVIDED FURTHER, HOWEVER, that with respect to an Available
Cash Offer, if the aggregate amount of Exchange Notes of a series tendered
exceeds the Maximum Principal Amount, then the applicable Trustee shall select
Exchange Notes of such series to be purchased ratably from each Holder that
tendered Exchange Notes of such series such that the ratio of the principal
amount of the Exchange Notes of such series to be purchased from each Holder
that tendered Exchange Notes of such series to the aggregate principal amount of
Exchange Notes of such series tendered by such Holder shall, as nearly as
practicable and subject to rounding, equal the ratio of the Maximum Principal
Amount to the aggregate principal amount of the Exchange Notes of such series
tendered with respect to such Available Cash Offer. The Issuer will notify the
Holders of the results of an Available Cash Offer or Change of Control Offer on
or as soon as practicable after the applicable Purchase Payment Date.

         The Issuer will comply with Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder, to the extent such laws and
regulations are applicable to an Available Cash Offer or a Change of Control
Offer. To the extent that the provisions of any securities laws or regulations
conflict with the provisions of the covenant described hereunder, the Issuer
shall comply with the applicable securities laws and regulations and shall not
be deemed to have breached its obligations under the covenant described
hereunder by virtue thereof.

         SOURCE OF FUNDS TO PURCHASE NOTES. In the event of an Available Cash
Offer, the payment for the tendered Exchange Notes shall be taken from amounts
held as Available Cash in the Revenue Account.

         In the event of a Change of Control Offer, the Change of Control
Payment shall be taken from the Revenue Account to the extent of funds available
therein. As discussed under "RISK FACTORS--LIMITATION ON CHANGE OF CONTROL,"
there can be no assurance that, on the Change of Control Payment Date, amounts
in the Revenue Account will be sufficient to pay for all the Exchange Notes
tendered pursuant to the Change of Control Offer.

REGISTRATION RIGHTS

         In connection with the issuance of the Existing Notes, the Company
entered into a Registration Rights Agreement with the Initial Purchasers
pursuant to which the Company agreed, for the benefit of the Holders of the
Existing Notes, at the Company's expense, to use its reasonable best efforts to
cause the Registration Statement of which this Prospectus forms a part to be
declared effective under the Securities Act.


                                      -88-
<PAGE>

         Promptly after the Registration Statement of which this Prospectus
forms a part is declared effective, the Company has agreed to commence the
Exchange Offer and to keep the Exchange Offer open not less than 30 days (or
longer if required by applicable law).

         In the event that any changes in law or applicable interpretations of
the staff of the Commission do not permit the Company to effect the Exchange
Offer or in certain other circumstances, the Company has agreed, at the
Manager's expense, to (i) as promptly as practicable, and in any event on or
prior to 30 days after such filing obligation arises, file or cause to be filed
with the Commission the Shelf Registration Statement covering resales of the
Existing Notes, (ii) use reasonable best efforts to cause the Shelf Registration
Statement to be declared effective under the Securities Act and (iii) use
reasonable best efforts to keep effective the Shelf Registration Statement for
up to two years after its effective date (or such shorter period that will
terminate when all the Existing Notes covered thereby have been sold pursuant
thereto or in certain other circumstances). The Company has agreed to use
reasonable best efforts in the event of the filing of a Shelf Registration
Statement, to provide to each Holder of the Existing Notes covered by the Shelf
Registration Statement copies of the prospectus that is a part of the Shelf
Registration Statement, notify each such Holder when the Shelf Registration
Statement for the Existing Notes has become effective and take certain other
actions as are required to permit unrestricted resales of the Existing Notes. A
Holder of Existing Notes that sells such Existing Notes pursuant to the Shelf
Registration Statement generally will be required to be named as a selling
securityholder in the related prospectus and to deliver a prospectus to the
purchaser, will be subject to certain of the civil liability provisions under
the Securities Act in connection with such sales and will be bound by the
provisions of the Registration Rights Agreement that are applicable to such
Holder (including certain indemnification obligations). In addition, each Holder
of the Existing Notes will be required to deliver certain information to be used
in connection with the Shelf Registration Statement in order to have its
Existing Notes included thereunder.

         If the Exchange Offer is not consummated by February 3, 1998,
Additional Interest will accrue on the Existing Notes from such date to the date
the Exchange Offer is consummated, at a rate of 0.50% of the principal amount
thereof per annum, which Additional Interest is payable semiannually in arrears
on each Payment Date. Interest on the First Priority Exchange Notes will accrue
at a rate of 11% and interest on the Second Priority Exchange Notes will accrue
at a rate of 12 1/2% per annum to reflect the 0.50% of additional Additional
Interest until the earlier of consummation of the Exchange Offer or such time as
the Exchange Notes may be freely resold pursuant to Rule 144(k). Additional
charter hire payments are or will be payable under the Charters in an aggregate
amount, in each case, equal to such Additional Interest.

         Upon consummation of the Exchange Offer, the Company generally will
have satisfied its obligations under the Registration Rights Agreement with
respect to registration of the Existing Notes and generally will have no further
obligation to register the Existing Notes.

         A copy of the Registration Rights Agreement has been filed as an
exhibit to the Registration Statement of which this Prospectus forms a part.

TRUST ACCOUNTS


                                      -89-
<PAGE>

         Pursuant to the Intercreditor Agreement, the Collateral Agent has
established and is maintaining the Pre-Funding Account, Capitalized Interest
Account, Revenue Account, Letter of Credit Account, Operating Account, Casualty
Account, Termination Account and Collateral Account (collectively, the "Trust
Accounts") each of which was established in the name of the Collateral Agent for
the benefit of the Holders of the Exchange Notes, the Letter of Credit Issuer
and the Trustees. The Manager has and will have the right to withdraw amounts
held in the Operating Account. See "--OPERATING ACCOUNT."

         PRE-FUNDING ACCOUNT. The Issuer has deposited or will deposit, as
applicable, into an account (the "Pre-Funding Account"): (i) on the Original
Closing Date, (A) an amount sufficient to pay the Purchase Price of each Vessel;
and (B) an amount sufficient to pay (1) all fees allocable to each Vessel and
due and payable prior to the Delivery Date of such Vessel, including the
Manager's Fees and those payable to the Letter of Credit Issuer and (2) all
amounts in respect of the cost of Vessels' supplies and (ii) from time to time
income earned on Temporary Cash Investments from amounts on deposit in the
Pre-Funding Account. In connection with the foregoing deposits, the Issuer has
delivered on the Original Closing Date to the Trustees and the Collateral Agent
a verification report of a nationally recognized firm of independent accountants
to the effect that funds deposited pursuant to clause (i)(A) above will provide
cash at such times and in such amounts as will be sufficient to pay, when due,
each installment payment for the Purchase Price of each Vessel. Notwithstanding
the delivery of the aforementioned report, there can be no assurance that the
funds deposited pursuant to clause (i)(A) above, will provide cash at such times
and in such amounts as will be sufficient to pay, when due, each installment
payment for the Purchase Price of each Vessel.

         The Collateral Agent has made or will make, as applicable payments from
the Pre-Funding Account as follows: (i) on each Vessel Purchase Installment Date
(as defined) for each Vessel, an amount equal to the installment then due with
respect to such Vessel to be remitted to the Builders as an installment payment
of the Purchase Price of such Vessel, PROVIDED that each of the Trustees and the
Collateral Agent has received written notice of such Vessel Purchase Installment
Date at least three Business Days prior to such date, and PROVIDED FURTHER, that
no material default exists under the related Building Contract; (ii) at any time
and from time to time, PROVIDED that the Collateral Agent and the Trustees have
received a written request for such payment at least three Business Days prior
to such date of withdrawal, an amount equal to that portion of any fee allocable
to a Vessel and then due and payable prior to the Delivery Date of such Vessel
pursuant to the terms of the Management Agreement or the Letter of Credit
Reimbursement Agreement, to be remitted to the Manager or the Letter of Credit
Issuer, as the case may be; PROVIDED, HOWEVER, that amounts withdrawn from the
Pre-Funding Account to make payments as described in this clause (ii) shall not
in the aggregate exceed the sum of all amounts deposited into the Pre-Funding
Account pursuant to clause (i)(B)(1) of the preceding paragraph; (iii) on the
Delivery Date for each Vessel, PROVIDED that the conditions precedent set forth
in the Indentures and the Intercreditor Agreement have been satisfied, an amount
equal to (A) the final installment of the Purchase Price for such Vessel, to be
remitted to the Builders, plus (B) fees and expenses incurred in connection with
the recordation and filing of the related Security Agreements in the
Registration Jurisdiction related to such Vessel, to be remitted to the Manager;
(iv) on each Interest Payment Date occurring after the Contractual Delivery Date
of a Vessel and before the Delivery Date of such Vessel, an amount equal to the
interest accrued on the Allocated Principal Amount of the Notes for such Vessel
to be deposited in the Revenue Account; (v) if an Owner elects to terminate the
Building Contract for its Vessel due


                                      -90-
<PAGE>

to a material breach of such Building Contract by the Builders, an amount equal
to the remaining funds in the Pre-Funding Account to be deposited into the
Termination Account for application in redemption of such portion of the First
Priority Exchange Notes and untendered Existing First Priority Notes, if any, or
the Second Priority Exchange Notes and untendered Existing Second Priority
Notes, if any, as the case may be, as described above under
"--REDEMPTION--MANDATORY REDEMPTION UPON THE OCCURRENCE OF CERTAIN EVENTS;" (vi)
on the Delivery Date of the last Vessel, the amounts remaining in the
Pre-Funding Account after the payment of the final installment of the Purchase
Price to the Builders and the remittance of the fees and expenses incurred in
connection with the recordation and filing of the related Security Agreements in
the Registration Jurisdiction related to such Vessel to the Manager, to be
deposited into the Revenue Account; and (vii) any and all investment income
earned from Temporary Cash Investments held therein, for deposit in the
Capitalized Interest Account.

         CAPITALIZED INTEREST ACCOUNT. On the Original Closing Date, the
Collateral Agent, pursuant to the Intercreditor Agreement, deposited into an
account (the "Capitalized Interest Account") an amount which, together with the
investment income estimated to be earned thereon from Temporary Cash Investments
as well as any investment income from Temporary Cash Investments deposited
therein from the Pre-Funding Account, will be sufficient to pay interest
(excluding additional interest payable on such Exchange Notes pursuant to a
Registration Default) on the Allocated Principal Amount of the Notes for each
Vessel during the period prior to the Contractual Delivery Date of the related
Vessel. In connection with the foregoing deposit, the Issuer delivered on the
Original Closing Date to the Trustees and the Collateral Agent a verification
report of a nationally recognized firm of independent accountants to the effect
that the payments scheduled to be received, without reinvestment, on the
Temporary Cash Investments made with funds deposited in the Capitalized Interest
Account pursuant to this paragraph, together with amounts deposited in the
Capitalized Interest Account from the Pre-Funding Account as set forth above and
together with any cash, without reinvestment, deposited pursuant to this
paragraph, that was not invested on the Original Closing Date, will provide cash
at such times and in such amounts as will be sufficient to pay, when due,
interest on the Allocated Principal Amount of the Notes for each Vessel during
the period prior to the Contractual Delivery Date of such Vessel (excluding
additional interest payable on such Exchange Notes pursuant to a Registration
Default). Notwithstanding the delivery of the aforementioned report, there can
be no assurance that the funds deposited pursuant to this paragraph will provide
cash at such times and in such amounts as will be sufficient to pay, when due,
interest on the Allocated Principal Amount of the Notes for each Vessel during
the period prior to the Contractual Delivery Date of such Vessel.

         On each Interest Payment Date prior to the Contractual Delivery Date of
a Vessel, the Collateral Agent will withdraw from the Capitalized Interest
Account in respect of each such Vessel an amount equal to the interest accrued
on the Allocated Principal Amount of the Notes for such Vessel and shall deposit
such amount into the Revenue Account. In addition, if an Owner elects to
terminate the Building Contract for its Vessel due to a material breach of such
Building Contract by the Builders, then the remaining funds in the Capitalized
Interest Account shall be withdrawn from the Capitalized Interest Account and
deposited into the Termination Account for application in redemption of such
portion of the First Priority Exchange Notes and untendered Existing First
Priority Notes, if any, or the Second Priority Exchange Notes and untendered
Existing Second


                                      -91-
<PAGE>

Priority Notes, if any, as the case may be, as described above under
"--REDEMPTIONS--MANDATORY REDEMPTION UPON THE OCCURRENCE OF CERTAIN EVENTS."

         REVENUE ACCOUNT. The following amounts will be deposited into an
account (the "Revenue Account"): (i) on a daily basis, any and all revenue
(including charterhire) received by the Owners or the Manager in connection with
the employment of the Vessels; (ii) on the first Business Day of each month
following the Delivery Date of the first Vessel, income earned during the
preceding calendar month on Temporary Cash Investments from amounts on deposit
in the Revenue Account; (iii) Interest Draws; (iv) Working Capital Draws in an
amount equal to additional interest being paid or payable on the Allocated
Principal Amount of the Notes for each Vessel pursuant to a Registration Default
to the extent the balance remaining in the Capitalized Interest Account on an
Interest Payment Date prior to the acceptance of such Vessel is insufficient to
pay such additional interest; and (v) on the Delivery Date of the last Vessel,
any amounts remaining in the Pre-Funding Account after the payment of the final
installment of the Purchase Price to the Builders and the remittance of the fees
and expenses incurred in connection with the recordation and filing of the
related Security Agreements in the Registration Jurisdiction related to such
Vessel to the Manager. Deposits will also be made into the Revenue Account from
time to time (i) from certain withdrawals of funds from the Pre-Funding Account,
the Capitalized Interest Account and the Casualty Account, as described herein;
and (ii) from amounts held in the Termination Account to the extent Insurance
Proceeds exceed the related Total Loss Payment. The Collateral Agent will
disburse funds on deposit in the Revenue Account from time to time as described
below under "--PRIORITIES OF PAYMENTS--REVENUE ACCOUNT."

         LETTER OF CREDIT ACCOUNT. No later than the Business Day prior to each
Interest Payment Date with respect to which the Collateral Agent has made an
Interest Draw under the Letter of Credit, the Collateral Agent will, pursuant to
the Intercreditor Agreement, deposit the Draw Amount into an account (the
"Letter of Credit Account"). On each Interest Payment Date after the Delivery
Date of the first Vessel as described under "--PRIORITIES OF PAYMENT--LETTER OF
CREDIT ACCOUNT," the Collateral Agent will be required to withdraw from the
Letter of Credit Account such Draw Amount and shall deposit such amount into the
Revenue Account.

         OPERATING ACCOUNT. On the first Business Day of each calendar month,
commencing after the Delivery Date of the first Vessel, the Collateral Agent
will, from amounts withdrawn from the Revenue Account as described under
"--PRIORITIES OF PAYMENT--REVENUE ACCOUNT," deposit into an account (the
"Operating Account") an amount (the "Monthly Operating Deposit") by which the
Budgeted Monthly Operating Balance then in effect exceeds the balance of funds
in the Operating Account as of the opening of business on such first Business
Day, as certified by the Manager to the Trustees and the Collateral Agent as of
such first Business Day. In addition, on and after any Business Day commencing
90 days prior to the Delivery Date of the first Vessel, as reasonably expected
by the Issuer and evidenced by an Officer's Certificate, upon receipt by the
Collateral Agent of a written request from the Manager that a Working Capital
Draw be made under the Letter of Credit to the extent the funds in the Operating
Account are insufficient to meet actual operating expenses (including the
Manager's Fees and the fees of GEBAB under the Technical Supervision Agreement
and the Commercial Management Agreement) for which the Manager has received an
invoice, the Collateral Agent will make a Working Capital Draw in the amount
requested by the


                                      -92-
<PAGE>

Manager (but not to exceed the maximum amount then available under the Letter of
Credit for Working Capital Draws) and deposit the Draw Amount into the Operating
Account.

         CASUALTY ACCOUNT. The Collateral Agent will deposit into an account
(the "Casualty Account") (i) any cash proceeds (other than amounts representing
the Refund Amount or the proceeds of the Performance Bonds or any Building
Contract Guarantee) from the exercise of remedies against a Builder in respect
of any Vessel; and (ii) any Insurance Proceeds (other than with respect to a
Total Loss) payable to the Collateral Agent as assignee of the Owners and the
Manager, pursuant to the terms of the Insurance Policies, as described herein
under "THE MORTGAGES--INSURANCE."

         In accordance with the terms of the Intercreditor Agreement, the
Collateral Agent will apply amounts deposited into the Casualty Account to pay
for the repair or salvage of any of the Vessels, if, in each case, the following
conditions have been met: (i) if no Event of Default has occurred or is
continuing, the Manager has certified to the Trustees and the Collateral Agent
that such repairs are necessary or desirable for the use, operation and
maintenance of such Vessel; and (ii) if an Event of Default has occurred and is
continuing, the Collateral Agent, in its sole discretion, has determined to
apply such amounts to pay for the repair or salvage of such Vessel. If repair of
such Vessel is deemed not to be desirable by the Manager or the Collateral
Agent, pursuant to either clause (i) or (ii) above, such amounts will be held
(x) in the Casualty Account if no Event of Default has occurred or is
continuing, and (y) in the Collateral Account if an Event of Default has
occurred and is continuing.

         The Collateral Agent may withdraw funds from the Casualty Account on
any Interest Payment Date, to cover any deficiency which may arise if funds
available in the Revenue Account are insufficient to pay amounts required to be
paid from the Revenue Account on such Interest Payment Date as described under
"--PRIORITIES OF PAYMENTS--REVENUE ACCOUNT," but only to the extent that funds
on deposit in the Casualty Account are not designated for payment of the repair
or salvage of the related Vessel giving rise to the deposit of such funds.

         TERMINATION ACCOUNT. In the event of a Total Loss of a Vessel or in the
event of a termination by an Owner of its Building Contract, the Collateral
Agent will deposit into an account (the "Termination Account") any Insurance
Proceeds or the Refund Amounts with respect to the related Vessel and any other
Vessel that has not been accepted as of such date of termination, if any, and
any amounts collected in respect of the related Building Contract Guarantees and
Performance Bonds, as the case may be. See "--REDEMPTIONS--MANDATORY REDEMPTION
UPON THE OCCURRENCE OF CERTAIN EVENTS." The Refund Amounts and any amounts
collected in respect of the related Building Contract Guarantees and the
Performance Bonds, together with the amounts withdrawn from the Pre- Funding
Account and the Capitalized Interest Account shall be withdrawn from the
Termination Account to be applied first, to the Letter of Credit Issuer in an
aggregate amount equal to the sum of (i) any accrued and unpaid fees owing under
the Letter of Credit Reimbursement Agreement, (ii) all Working Capital Draws
made with respect to such Vessels which remain unreimbursed, together with
accrued and unpaid interest thereon and (iii) the Allocated Portion of Interest
Draws for such Vessels which remain unreimbursed, together with accrued and
unpaid interest thereon and then, for the redemption of the First Priority
Exchange Notes and untendered Existing First Priority Notes, if any, or the
Second Priority Exchange Notes and untendered Existing Second Priority Notes, if
any,


                                      -93-
<PAGE>

as the case may be, as required by the terms of the Indentures. The Insurance
Proceeds in the event of a Total Loss will be withdrawn from the Termination
Account and disbursed by the Collateral Agent, in the following order of
priority:

         FIRST: to the Letter of Credit Issuer, the Trustees and the Collateral
Agent, an amount equal to any accrued and unpaid Letter of Credit Fees and
Trustee and Collateral Agent fees and all reasonable expenses and charges
incurred by or on behalf of the Letter of Credit Issuer, the Trustees and the
Collateral Agent in connection with the ascertainment or protection of their
respective rights and the pursuance of their respective remedies under the
Indentures, the Letter of Credit Reimbursement Agreement or any of the Security
Agreements (including the reasonable fees and expenses of counsel);

         SECOND: to the Letter of Credit Issuer, an amount equal to all Working
Capital Draws made with respect to such Vessel which remain unreimbursed,
together with interest thereon payable pursuant to the Letter of Credit
Reimbursement Agreement;

         THIRD: to the Letter of Credit Issuer, an amount equal to the Allocated
Portion of Interest Draws for a Vessel which remain unreimbursed, together with
interest thereon payable pursuant to the Letter of Credit Reimbursement
Agreement;

         FOURTH: to the First Priority Trustee for the benefit of the Holders of
the First Priority Exchange Notes and untendered Existing First Priority
Exchange Notes, if any, an amount equal to any accrued and unpaid interest in
respect of the First Priority Exchange Notes and untendered
Existing First Priority Exchange Notes, if any, then outstanding;

         FIFTH: to the Second Priority Trustee for the benefit of the Holders of
the Second Priority Exchange Notes and untendered Existing Second Priority
Exchange Notes, if any, an amount equal to any accrued and unpaid interest in
respect of the Second Priority Exchange Notes and untendered
Existing Second Priority Exchange Notes, if any, then outstanding;

         SIXTH: to the First Priority Trustee for the benefit of the Holders of
the First Priority Exchange Notes and untendered Existing First Priority
Exchange Notes, if any, an amount equal to the outstanding principal of the
First Priority Exchange Notes and untendered Existing First Priority
Exchange Notes, if any;

         SEVENTH: to the Second Priority Trustee for the benefit of the Holders
of the Second Priority Exchange Notes and untendered Existing Second Priority
Exchange Notes, if any, an amount equal to the outstanding principal of the
Second Priority Exchange Notes and untendered Existing Second Priority Exchange
Notes, if any; and

         EIGHTH:  to the Revenue Account, any remaining amounts.

         COLLATERAL ACCOUNT. The Collateral Agent will deposit into an account
(the "Collateral Account"): (i) the cash proceeds of any sale of, or other
realization upon, all or any part of the Collateral upon exercise by the
Collateral Agent of any rights and remedies under the Intercreditor Agreement
and the Indentures, as described below under "--DEFAULTS;" (ii) any other
amounts


                                      -94-
<PAGE>

received by the Collateral Agent upon the occurrence and continuation of an
Event of Default, if such amounts are not otherwise applied as indicated below
under "--PRIORITIES OF PAYMENT--REVENUE ACCOUNT;" (iii) any other amounts
received by the Collateral Agent pursuant to any of the Security Agreements for
which the Intercreditor Agreement does not specify a Trust Account into which
such amount is to be deposited; and (iv) upon the occurrence and continuance of
an Event of Default, at the instruction of the Trustees and the Letter of Credit
Issuer, funds from any other Trust Account. Funds on deposit in the Collateral
Account will be distributed in accordance with "--APPLICATION OF PROCEEDS
FOLLOWING AN EVENT OF DEFAULT" below.

PRIORITIES OF PAYMENT

         The Collateral Agent will disburse amounts from the Revenue Account,
the Letter of Credit Account and the Operating Account in the manner, and in the
order of priority, described below.

         REVENUE ACCOUNT. On the first Business Day of each calendar month, the
Collateral Agent will withdraw funds from the Revenue Account and apply such
funds in the following order of priority:

                                      -103-
<PAGE>

and interest shall be due and payable immediately. If an Event of Default
relating to certain events of bankruptcy, insolvency or reorganization of the
Issuer occurs and is continuing, the principal of and interest on all the
Exchange Notes will IPSO FACTO become and be immediately due and payable without
any declaration or other act on the part of the Trustees or any Holders of the
Exchange Notes. Under certain circumstances, the Holders of a majority in
principal amount of the outstanding Exchange Notes of a series may rescind any
such acceleration with respect to the Exchange Notes of such series and its
consequences. Subject to the provisions of the Indentures relating to the duties
of the Trustees, in case an Event of Default occurs with respect to a series of
Notes and is continuing, the applicable Trustee will be under no obligation to
exercise any of the rights or powers under the applicable Indenture at the
request or direction of any of the Holders of the Exchange Notes of such series
unless such Holders have offered to such Trustee reasonable indemnity or
security against any loss, liability or expense. Except to enforce the right to
receive payment of principal, premium (if any) or interest when due, no Holder
of an Exchange Note, of a series may pursue any remedy with respect to the
applicable Indenture or the Exchange Notes of such series unless (i) such Holder
has previously given the applicable Trustee notice that an Event of Default is
continuing; (ii) Holders of at least 25% in principal amount of the outstanding
Exchange Notes of such series have requested such Trustee to pursue the remedy;
(iii) such Holders have offered such Trustee reasonable security or indemnity
against any loss, liability or expense; (iv) such Trustee has not complied with
such request within 60 days after the receipt thereof and the offer of security
or indemnity; and (v) the Holders of a majority in principal amount of the
outstanding Exchange Notes of such series have not given such Trustee a
direction inconsistent with such request within such 60-day period. Subject to
certain restrictions, the Holders of a majority in principal amount of the
outstanding Notes of a series are given the right to direct the time, method and
place of conducting any proceeding for any remedy available to the applicable
Trustee or of exercising any trust or power conferred on the applicable Trustee.
Such Trustee, however, may refuse to follow any direction that conflicts with
law or the applicable Indenture or that such Trustee determines is unduly
prejudicial to the rights of any other Holder of an Exchange Note of such series
or that would involve such Trustee in personal liability.

         Each Indenture provides that if a Default occurs and is continuing and
is known to the Trustee, such Trustee must mail to each Holder of the Exchange
Notes of the applicable series notice of the Default within 90 days after it
occurs. Except in the case of a Default in the payment of principal of or
interest on an Exchange Note of a series, the applicable Trustee may withhold
notice if and so long as a committee of its trust officers determines that
withholding notice is not opposed to the interest of the Holders of the Exchange
Notes of such series. In addition, the Issuer is required to deliver to each
Trustee, within 120 days after the end of each fiscal year, a certificate
indicating whether the signers thereof know of any Default that occurred during
the previous year. The Issuer also is required to deliver to each Trustee,
within 30 days after the occurrence thereof, written notice of any event which
would constitute certain Defaults, their status and what action the Issuer is
taking or proposes to take in respect thereof.

NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

         A director, officer or employee, as such, of the Issuer or Holdings
shall not have any liability for any obligations of the Issuer or Holdings, as
the case may be, under the Indentures, the Security Agreements or the
Intercreditor Agreement. In addition, a director, officer, employee or
stockholder, as such, of the Owners shall not have any liability for any
obligations of the Owners under the


                                      -104-
<PAGE>

Guarantees or for any claim based on, in respect of or by reason of such
obligations or their creation.

AMENDMENTS AND WAIVERS

         Subject to certain exceptions, each Indenture may be amended with the
consent of the Holders of a majority in principal amount of the Exchange Notes
of the applicable series then outstanding (including consents obtained in
connection with a tender offer or exchange for the Exchange Notes of such
series) and any past Default or Event of Default or compliance with any
provisions may also be waived with the consent of the Holders of a majority in
principal amount of the Exchange Notes of such series then outstanding. However,
without the consent of each Holder of an outstanding Exchange Note of a series
affected thereby, no amendment may, among other things, (i) reduce the amount of
Exchange Notes of such series whose Holders must consent to an amendment; (ii)
reduce the rate of or extend the time for payment of interest on any Exchange
Note of such series; (iii) reduce the principal of or extend the Stated Maturity
of any Exchange Note of such series; (iv) reduce the premium payable upon the
redemption of any Note of such series or change the time at which any Exchange
Note of such series may be redeemed as described under "--REDEMPTIONS" above;
(v) make any Exchange Note of such series payable in money other than that
stated in the Exchange Note of such series; (vi) impair the right of any Holder
of the Exchange Notes of such series to receive payment of principal of and
interest on such Holder's Exchange Notes or untendered Existing Notes, if any,
of such series on or after the due dates therefor or to institute suit for the
enforcement of any payment on or with respect to such Holder's Exchange Notes of
such series; (vii) make any change in the amendment provisions which require
each Holder's consent or in the waiver provisions; (viii) make any change in any
Guarantee or Security Agreements that would adversely affect the Holders of such
series or terminate the Lien of the Indenture or any Security Agreement on any
property at any time subject thereto or deprive the Holder of the security
afforded by the Lien of such Indenture or the Security Agreements; or (ix) make
any change in the covenants described under "--CERTAIN COVENANTS" that would
adversely affect the Holders of such series.

         Without the consent of any Holder of the Exchange Notes of a series,
the Issuer and related Trustee may amend the applicable Indenture or any
Security Agreement to cure any ambiguity, omission, defect or inconsistency, to
provide for the assumption by a successor corporation of the obligations of the
Issuer under such Indenture, to provide for uncertificated Exchange Notes of
such series in addition to or in place of certificated Exchange Notes of such
series (PROVIDED that such uncertificated Exchange Notes are issued in
registered form for purposes of Section 163(f) of the Code, or in a manner such
that such uncertificated Exchange Notes are described in Section 163(f)(2)(B) of
the Code), to add guarantees with respect to the Exchange Notes of such series,
to secure the Exchange Notes of such series, to add to the covenants of the
Issuer for the benefit of the Holders of the Exchange Notes or untendered
Existing Notes, if any, of such series or to surrender any right or power
conferred upon the Issuer, to make any change that does not adversely affect the
rights of any Holder of the Exchange Notes of such series or to comply with any
requirement of the SEC in connection with the qualification of the applicable
Indenture under the Trust Indenture Act.

         The consent of the Holders of the Exchange Notes of a series is not
necessary under the applicable Indenture to approve the particular form of any
proposed amendment. It is sufficient if such consent approves the substance of
the proposed amendment.


                                      -105-
<PAGE>

         After an amendment under an Indenture becomes effective, the Issuer is
required to mail to Holders of the Exchange Notes of the applicable series a
notice briefly describing such amendment. However, the failure to give such
notice to all Holders of the Exchange Notes of such series, or any defect
therein, will not impair or affect the validity of the amendment.

TRANSFER

         The Exchange Notes will be issued in registered form and will be
transferable (subject to applicable federal and state securities laws) only upon
the surrender of the Exchange Notes being transferred for registration of
transfer. The Issuer may require payment of a sum sufficient to cover any tax,
assessment or other governmental charge payable in connection with certain
transfers and
exchanges.

DEFEASANCE

         The Issuer at any time may terminate all its obligations under the
Exchange Notes of a series and the applicable Indenture ("legal defeasance"),
except for certain obligations, including those respecting the defeasance trust
and obligations to register the transfer or exchange of the Exchange Notes of
such series, to replace mutilated, destroyed, lost or stolen Exchange Notes of
such series and to maintain a registrar and paying agent in respect of the
Exchange Notes of such series. The Issuer at any time may terminate its
obligations under the Exchange Notes of a series and the applicable Indenture
under "--MANDATORY OFFERS TO PURCHASE EXCHANGE NOTES--OFFER TO PURCHASE UPON
CHANGE OF CONTROL" and under the covenants described under "--CERTAIN COVENANTS"
(other than the covenant described under "--MERGER AND CONSOLIDATION"), the
operation of the cross acceleration provision, the bankruptcy provisions with
respect to Owners, the judgment default provision, the guarantee default
provision and the security default provision described under "--Defaults" above
and the limitations contained in clause (iv) of the first paragraph under, and
in the third paragraph under, "--CERTAIN COVENANTS--MERGER AND CONSOLIDATION"
above ("COVENANT DEFEASANCE").

         The Issuer may exercise its legal defeasance option with respect to a
series of Exchange Notes notwithstanding its prior exercise of its covenant
defeasance option with respect to such series. If the Issuer exercises its legal
defeasance option with respect to a series of Exchange Notes, payment of the
Exchange Notes of such series may not be accelerated because of an Event of
Default with respect thereto. If the Issuer exercises its covenant defeasance
option with respect to a series of Exchange Notes, payment of the Exchange Notes
of such series may not be accelerated because of an Event of Default specified
in clause (iv), (vi), (vii) (with respect only to Owners), (viii), (ix), (x) or
(xi) under "--DEFAULTS" above or because of the failure of the Issuer to comply
with clause (iv) of the first paragraph, or with the third paragraph, under
"--CERTAIN COVENANTS--MERGER AND CONSOLIDATION" above. If the Issuer exercises
its legal defeasance option or its covenant defeasance option with respect to a
series of Exchange Notes, each Owner will be released from all its obligations
with respect to its Guarantee and the Security Agreements with respect to such
series, as applicable.

         In order to exercise either defeasance option with respect to a series
of Exchange Notes, the Issuer must irrevocably deposit in trust (the "Defeasance
Trust") with the applicable Trustee money


                                      -106-
<PAGE>

or U.S. Government Obligations for the payment of principal and interest on the
Exchange Notes of such series to redemption or maturity, as the case may be, and
must comply with certain other conditions, including delivery to the applicable
Trustee of an Opinion of Counsel to the effect that Holders of the Exchange
Notes of such series will not recognize income, gain or loss for federal income
tax purposes as a result of such deposit and defeasance and will be subject to
federal income tax on the same amounts and in the same manner and at the same
times as would have been the case if such deposit and defeasance had not
occurred (and, in the case of legal defeasance only, such Opinion of Counsel
must be based on a ruling of the Internal Revenue Service or other change in
applicable federal income tax law).

         Notwithstanding the foregoing, the exercise of either defeasance option
by the Issuer may not be enforceable if such defeasance improves the position of
Noteholders of either series of Exchange Notes as against any other creditor of
the Issuer, whether actual, contingent or otherwise. Furthermore, the Issuer may
not exercise its legal defeasance or covenant defeasance options unless the
Rating Agencies confirm to the applicable Trustee in writing that such exercise
will not result in a ratings decline with respect to either series of Exchange
Notes.

CONCERNING THE TRUSTEES

         United States Trust Company of New York is the Trustee under the First
Priority Indenture and has been appointed by the Issuer as Registrar and Paying
Agent with regard to the First Priority Exchange Notes and untendered Existing

         The Holders of a majority in principal amount of the outstanding
Exchange Notes of a series have the right to direct the time, method and place
of conducting any proceeding for exercising any remedy available to the
applicable Trustee, subject to certain exceptions. Each Indenture provides that
if an Event of Default occurs (and is not cured) thereunder, the applicable
Trustee will be required, in the exercise of its power, to use the degree of
care of a prudent person in the conduct of his own affairs. Subject to such
provisions, such Trustee is under no obligation to exercise any of its rights or
powers under such Indenture at the request of any Holder of Exchange Notes of
the applicable series, unless such Holder shall have offered to such Trustee
security and indemnity satisfactory to it against any loss, liability or expense
and then only to the extent required by the terms of such Indenture.

         Prior to the Delivery Date of the first Vessel, the Manager is
responsible for the payment of the fees and expenses of the Trustees and the
Collateral Agent. Thereafter, the fees and expenses of the Trustees and the
Collateral Agent shall be payable from amounts held in the Revenue Account. See
"--PRIORITIES OF PAYMENTS--REVENUE ACCOUNT."

GOVERNING LAW

         Each of the Indentures and the Intercreditor Agreement provides that
the Indentures, the Intercreditor Agreement, the Exchange Notes and each of the
Security Agreements, other than the Mortgages and the Issue of One Debenture,
are governed by, and construed in accordance with, the laws of the State of New
York without giving effect to applicable principles of conflicts of law to the

collectible within the United States. See "ENFORCEMENT OF CIVIL LIABILITIES."

principal amount of $1,000 and 7.66 Warrants, each Warrant entitling the holder
thereof to purchase one share of Holdings Common Stock at an exercise price of
$.01 per share, subject to adjustment. The Second Priority Notes and the
Warrants will not trade separately until the earlier to occur of (i) the
commencement of the Exchange Offer or the effectiveness of a shelf registration
statement with respect to the Second Priority Notes and (ii) such date as the
Initial Purchasers may in their discretion deem appropriate. See "DESCRIPTION OF
THE NOTES--REGISTERED EXCHANGE OFFER; REGISTRATION RIGHTS." See "DESCRIPTION OF
THE EXCHANGE NOTES" and "DESCRIPTION OF WARRANTS" for further information
concerning the Second Priority Notes and the Warrants, respectively. In
addition, see "DESCRIPTION OF CAPITAL STOCK" for additional information relating
to the Holdings Common Stock issuable upon exercise of the Warrants.

         The Warrants were issued under the Warrant Agreement dated as of August
7, 1997, between Holdings and United States Trust Company of New York, as
warrant agent (the "Warrant Agent"). Each Warrant, when exercised, will entitle
the holder thereof to receive one share of Holdings Common Stock. The exercise
price of $.01 per share with respect to all the shares of Holdings Common Stock
purchasable under the Warrants was paid by each initial purchaser from the
Initial Purchaser thereof as part of the purchase price of the Units.
Thereafter, no additional amounts shall be required to be paid upon exercise of
the Warrants. The Warrants will entitle the holders thereof to purchase in the
aggregate 25% of Holdings Common Stock on a fully diluted basis as of the date
of issuance of the Warrants. The number of shares of Holdings Common Stock is
subject to adjustment in certain cases referred to below. Unless exercised, the
Warrants will automatically expire on June 30, 2007.

                          DESCRIPTION OF CAPITAL STOCK

HOLDINGS

         As of the date hereof, there are 2,000,000 shares of Holdings Common
Stock outstanding and registered in the names of five shareholders in the
Register of Members of Holdings. The following summary does not purport to be
complete and is subject to, and is qualified in its entirety by, the Certificate
of Incorporation and the Memorandum and Articles of Association of Holdings,
copies of which may be obtained from Holdings or the Initial Purchasers upon
request, and by provisions of applicable law.

HOLDINGS COMMON STOCK

         As of the date hereof, Holdings will be authorized to issue up to
3,000,000 shares of Holdings Common Stock. In relation to all matters submitted
to a vote of stockholders, every holder of Holdings Common Stock who (being an
individual) is present in person or by proxy or (being a corporation) is present
by a duly authorized representative, not being himself a stockholder, shall, on
a show of hands, have one vote and, on a poll, every holder of Holdings Common
Stock entitled to vote shall have one vote for every share held. Accordingly,
the holders of Holdings Common Stock may from time to time in general meeting
increase or reduce the number of directors and may, by special resolution,
remove any director or by ordinary resolution appoint any person to be a
director. Holders of Holdings Common Stock may by ordinary resolution declare
dividends, but no dividend may exceed the amount recommended by the directors
out of funds legally available for the purpose. On a winding-up of Holdings, a
liquidator may divide among the holders of Holdings Common Stock rateably the
net assets of Holdings available after the payment of all debts and other
liabilities in accordance with applicable law and may, with the sanction of an
extraordinary resolution of the stockholders and any other sanction required by
applicable law, divide among the holders of Holdings Common Stock rateably in
specie the whole or any part of the assets of Holdings and may, for that
purpose, value any assets and determine how the division shall be carried out as
between them.

         There is included in the Articles of Association of Holdings a
provision, subject to Section 151 of the Companies Acts 1931 of the Isle of Man,
indemnifying every director or other officer of Holdings out of the assets of
Holdings against losses or liabilities which such director or officer may
sustain or incur in or about the execution of the duties of his office or
otherwise in relation thereto and confirming that no such director or other
officer shall be liable for any loss, damage or misfortune which may happen to
or be incurred by Holdings in the execution of the duties of his office or in
relation thereto.

                             BOOK-ENTRY REGISTRATION

         The Existing Notes sold to Qualified Institutional Buyers were, and the
Exchange Notes will be, originally issued in fully registered book-entry form,
and each of the Existing Notes and the Exchange Notes will be represented by a
global note (each a "Global Note") registered in the name of Cede & Co. ("Cede")
as the nominee of the Depository Trust Company ("DTC"). All references to
actions by holders shall, in respect of the applicable Global Note, refer to
actions


                                      -123-
<PAGE>

taken by DTC upon instruction from DTC Participants (as defined below), and all
references herein to distributions, notices, reports and statements to holders
shall refer, as the case may be, to distributions, notices, reports and
statements to DTC or Cede, as the registered holder of the Exchange Notes or to
DTC Participants for distribution to Beneficial Owners in accordance with DTC
procedures. DTC has advised the Company that DTC is a limited-purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC accepts securities for
deposit from its participating organizations ("Participants") and facilitates
the clearance and settlement of securities transactions between Participants in
such securities through electronic book-entry changes in accounts of
Participants, thereby eliminating the need for physical movement of
certificates. Participants include securities brokers and dealers, banks and
trust companies and clearing corporations and may include certain other
organizations. Indirect access to the DTC system is also available to others
such as banks, brokers, dealers and trust companies that clear through or
maintain a custodial relationship with a Participant, either directly or
indirectly ("Indirect Participants").

         The Company expects that pursuant to procedures established by the DTC,
(i) upon deposit of the applicable Global Note, DTC will credit the accounts of
Participants designated by the Exchange Agent with portions of the principal
amount of the applicable Global Note and (ii) ownership of the Exchange Notes
evidenced by the applicable Global Note will be shown on, and the transfer of
ownership thereof will be effected only through, records maintained by DTC (with
respect to the interests of DTC's Participants), DTC's Participants and DTC's
Indirect Participants. Consequently, the ability to transfer Existing Notes or
Exchange Notes evidenced by the applicable Global Note will be limited to such
extent.

         So long as Cede is the registered owner of any Exchange Notes, Cede
will be considered the sole holder under the Indentures of any Exchange Notes
evidenced by the applicable Global Note. Beneficial owners of Exchange Notes
evidenced by the applicable Global Note will not be considered the owners or
holders thereof under the Indentures for any purpose, including with respect to
the giving of any directions, instructions or approvals to the Indenture
Trustees thereunder. Neither the Company nor the Indenture Trustee will have any
responsibility or liability for any aspect of the records of the DTC or for
maintaining, supervising or reviewing any records of the DTC relating to the
Exchange Notes. Payments in respect of the principal of, premium, if any, and
interest, on any Exchange Notes registered in the name of Cede on the applicable
record date will be payable by the Indenture Trustees to or at the direction of
Cede in its capacity as the registered holder under the Indentures. Under the
terms of the Indentures, the Issuer, and the Indenture Trustee may treat the
persons in whose names Exchange Notes including the applicable Global Note, are
registered as the owners thereof for the purpose of receiving such payments.
Consequently, neither the Issuer or the Indenture Trustee has or will have any
responsibility or liability for the payment of such amounts to beneficial owners
of Exchange Notes. The Company believes, however, that it is currently the
policy of the DTC to immediately credit the accounts of the relevant
Participants with such payments, in amounts proportionate to their respective
holdings of beneficial interests in the relevant security as shown on the
records of the DTC. Payments by DTC's Participants and DTC's Indirect
Participants to the beneficial owners of


                                      -124-
<PAGE>

Exchange Notes will be governed by standing instructions and customary practice
and will be the responsibility of DTC's Participants or DTC's Indirect
Participants. Subject to certain conditions, any beneficial owner of the
applicable Global Note may obtain, through the Direct Participant through which
such beneficial owner directly or indirectly holds beneficial interest, a
certificated Exchange Note or Exchange Notes, in exchange for all or part of
such beneficial interest. In addition, the Exchange Notes will be issued in
fully registered, certificated form to beneficial owners, or their nominees,
rather than to DTC or its nominee, if DTC advises the Indenture Trustees in
writing that it is no longer willing or able or qualified to discharge properly
its responsibilities as depository with respect to the Exchange Notes and the
Issuer, is unable to locate a qualified successor or if the Issuer elects to
terminate the book-entry system through DTC. In such event, the Indenture
Trustees will notify all beneficial owners through DTC Participants of the
availability of such certificated Exchange Notes. Upon surrender by DTC of the
registered global certificates representing the Exchange Notes and receipt of
instructions for re-registration, the Indenture Trustees will re-issue the
Exchange Notes in certificated form to beneficial owners or their nominees. Such
certificated Exchange Notes will be transferable and exchangeable at the office
of the Indenture Trustees upon compliance with the requirements set forth in the
Indentures.

             DESCRIPTION OF LETTER OF CREDIT REIMBURSEMENT AGREEMENT

         The Letter of Credit was issued pursuant to a Letter of Credit
Reimbursement Agreement and Guaranty dated as of the Original Closing Date among
the Letter of Credit Issuer, the participating banks from time to time party
thereto (together with the Letter of Credit Issuer, the "Letter of Credit
Banks"), the Issuer, Holdings and the Owners (the "Letter of Credit
Reimbursement Agreement"). The Letter of Credit Reimbursement Agreement shall
provide that Interest Draws and Working Capital Draws shall be repaid by the
Issuer, together with interest accrued thereon, on the first Business Day of
each calendar month to the extent of amounts available in the Revenue Account as
described under "DESCRIPTION OF THE EXCHANGE NOTES--PRIORITIES OF PAYMENT
- --REVENUE ACCOUNT." The Issuer has agreed to instruct the Collateral Agent to
make (i) additional Interest Draws to repay any portion of any Interest Draw and
accrued interest thereon that remains unpaid 35 days from the date of such
Interest Draw and (ii) additional Working Capital Draws to repay any portion of
any Working Capital Draw and accrued interest thereon that remains unpaid 35
days from the date of such Working Capital Draw. The Issuer further agreed to
instruct the Collateral Agent to make additional Interest Draws to the extent
funds are not available in the Revenue Account on the first Business Day of each
calendar month to pay any fees due under the Letter of Credit Reimbursement
Agreement. Any outstanding principal amount of Draws not repaid from amounts in
the Revenue Account shall be payable from proceeds of Collateral. Unreimbursed
amounts drawn under the Letter of Credit bear interest at the Letter of Credit
Issuer's cost of funds from time to time plus 1.25% per annum. The Issuer is
required to pay to the Letter of Credit Issuer (a) a fronting fee equal to 0.25%
per annum on the aggregate outstanding face amount of the Letter of Credit, (b)
a participation fee equal to 1.00% per annum on the aggregate outstanding face
amount of the Letter of Credit and (c) an underwriting fee prior to the issuance
of the Letter of Credit equal to 1.25% of the maximum face amount of the Letter
of Credit. The reimbursement obligations of the Issuer under the Letter of
Credit Reimbursement Agreement are guaranteed by each of the Owners and are
secured by the Collateral. To the extent such obligations are not repaid from
the Revenue Account or from additional Draws, proceeds of Collateral will be
applied to repayment of the reimbursement obligations prior to the repayment of
obligations in respect of the Notes.

         The Letter of Credit Reimbursement Agreement contains representations
and warranties similar to those contained in the Purchase Agreement, and
incorporates by reference, for the benefit of the Letter of Credit Issuer, each
of the covenants contained in the Indentures. The following events, among
others, constitute events of default under the Letter of Credit Reimbursement
Agreement unless waived by the required Letter of Credit Banks: (i) the Issuer
shall fail to pay the Letter of Credit Issuer when due any amounts drawn under
the Letter of Credit, any interest thereon or any fees due under the Letter of
Credit Reimbursement Agreement, (ii) the Issuer, Holdings or any of the Owners
shall fail to observe or perform any other covenant, agreement or restriction
contained or incorporated by reference in the Letter of Credit Reimbursement
Agreement, and, in certain cases, applicable grace periods have expired, (iii)
any representation, warranty, certification or statement made by the Issuer,
Holdings or any of the Owners in the Letter of Credit Reimbursement Agreement or
in any certificate, financial statement or other document delivered pursuant
thereto shall prove to have been incorrect in any material respect when made and
(iv) certain events of bankruptcy or insolvency of the Issuer, Holdings or any
of the Owners. Upon the occurrence of an event of default under the Letter of
Credit Reimbursement Agreement, the Letter of Credit Issuer shall have the right
to notify the Collateral Agent that the Letter of Credit will be terminated
within five days, which


                                      -126-
<PAGE>

notice would enable the Trustees to accelerate the maturity of the Notes and to
instruct the Collateral Agent to make an Interest Draw on the Letter of Credit.

         The Letter of Credit Reimbursement Agreement provides that amounts
available under the Letter of Credit shall be reduced on a PRO RATA basis upon
the occurrence of a redemption of the Notes as described under "DESCRIPTION OF
THE EXCHANGE NOTES--OPTIONAL REDEMPTION" and "--MANDATORY REDEMPTION UPON THE
OCCURRENCE OF CERTAIN EVENTS."

Mortgage and Permitted Liens);

         PRIORITY OF LIEN. Each Owner will represent and warrant that it is
constituting in favor of the Collateral Agent a first preferred ship mortgage on
its Vessel to secure the punctual payment of each of the amounts due under its
Guarantee and the performance and observance of and compliance with all the

         CUSTOMARY REPRESENTATIONS AND WARRANTIES. Each Owner will make
additional customary representations and warranties regarding such Owner and its
Vessel.

CERTAIN COVENANTS

         Each Mortgage contains, among other things, the following covenants:

         OPERATION OF VESSEL. No Owner will cause or permit its Vessel to be
operated in any manner contrary to law, will engage in unlawful trade, violate
any applicable law or carry any cargo that would expose the Vessel to penalty,
confiscation, forfeiture, capture or condemnation or do, suffer or permit to be
done anything which can or may injuriously affect the registration or enrollment
of


                                      -128-
<PAGE>

its Vessel under the laws and regulations of the Republic of Liberia, or any
jurisdiction of registration which at the time is generally deemed acceptable by
institutional lenders to the shipping industry, as determined in good faith by
such Owner, and will at all times keep its Vessel duly
documented thereunder.

         LIMITATION ON EMPLOYMENT OF VESSELS IN WAR ZONES. Each Owner will be
required to ensure that, in the event of hostilities in any part of the world,
its Vessel is not employed in carrying any goods which are declared contraband,
nor allowed in any zone in respect of which the war risks insurers have
withdrawn coverage for such Vessel, nor allowed to trade in any zone which is
declared a war zone by the war risks insurers, unless such Owner has made
arrangements with such insurers for the payment of additional premiums required
to maintain the relevant insurances in force.

         LIMITATION ON ACTIVITIES OUTSIDE INSURANCE POLICIES. Each Owner will be
required to ensure that its Vessel is not employed in any manner or for any
purpose excepted from any of the Insurance Policies, or for the purpose of
carriage of goods of any description excepted from the Insurance Policies and
shall not do or permit to be done anything which could reasonably be expected to
invalidate any Insurance Policies.

         MAINTENANCE OF INSURANCE. Each Owner will be required to maintain
insurance with respect to its Vessel, as described below under "--Insurance,"
and will assign the Insurance Policies to the Collateral Agent to be held for
the benefit of the Holders, the Trustees and the Letter of Credit
Issuer.

         LIMITATION ON LIENS. Except for the lien of the Mortgage and certain
other Permitted Liens, no Owner will have any right, power or authority to
create, incur or permit to be placed or imposed or continued any lien,

shall be, in so far as due diligence can make her so, tight, staunch, strong and
well and sufficiently tackled, apparelled, furnished, equipped and in every
respect seaworthy and in at least as good operating condition as when originally
delivered by the Builders, ordinary wear and tear excepted; and will keep the
Vessel, or cause her to be kept in such condition, as will entitle her to the
highest classification of the Classification Society, and annually will furnish
the Collateral Agent a certificate by the Classification Society that such
classification is maintained.

         TRANSFER OF FLAG OR SALE OF VESSEL. No Owner will transfer or change

institutional lenders to the shipping industry, as determined in good faith by
the Owners, as permitted by the terms of the Indentures. Except as permitted by
the terms of the Indentures, no Owner will sell, mortgage, demise, charter or
transfer its Vessel.


                                      -129-
<PAGE>

INSURANCE

         Each Owner, at its own expense, will be required to insure its Vessel
against all risks, whether marine or war, and all risks of navigation, operation
and maintenance. In addition, each Owner will be required to keep its Vessel
insured against all protection and indemnity risks in the name of the Owner. The
protection and indemnity insurance shall include cover against liabilities to
persons who have suffered any loss, damage or injury whatsoever in connection
with anything done or not done by the Vessel and/or the related Owner in
connection with the Vessel or the employment or use thereof (including in
connection with any oil or other substance emanating from the Vessel or any
other vessel with which the Vessel may be involved in collision) and against
liability under OPA 90. Pursuant to each Mortgage, each Owner will also obtain
loss of hire hull and machinery insurance, loss of hire war risks insurance,
drug seizure insurance and confiscation, expropriation, nationalization and
detainment insurance in a form which is substantially equivalent to the coverage
carried by other responsible and experienced companies engaged in the operation
of vessels similar to its Vessel and with insurance companies, underwriters,
funds, mutual insurance associations or clubs of recognized standing. No
insurance will provide for a deductible amount in excess of $1,000,000 per
occurrence. Under each such insurance policy, each Owner will cause the
Collateral Agent to be named an additional insured and will cause the insurers
under such policies to waive any liability of the Collateral Agent for premiums
or calls payable under such policies.

         For purposes of insurance against total loss, each Vessel is to be
insured for an amount not less than the greater of (a) its fair value and (b)
the Total Loss Payment with respect to such Vessel. Unless the Collateral Agent
shall have otherwise directed, any loss involving damage to a Vessel which is
not in excess of $1,000,000 may be deposited into the Operating Account. No
policy is to be cancellable or subject to lapse without at least 7 Business Days
prior notice to the Trustees and the Collateral Agent.

         In the event of an actual, constructive or compromised total loss of
its Vessel, any adjustment or compromise of such loss by the Owner will be at
the highest amount reasonably obtainable, and all insurance or other payments
for such loss will be applied as set forth above under "DESCRIPTION OF THE
EXCHANGE NOTES -- REDEMPTIONS -- MANDATORY REDEMPTION UPON THE OCCURRENCE OF
CERTAIN EVENTS." Unless the Collateral Agent shall have given its prior consent,
each insurance policy shall include a provision stating that no breach of
warranty or condition or want of due diligence on the part of the Owner or any
agent of the Owner shall defeat recovery of any claim by the Collateral Agent;
PROVIDED, HOWEVER, in the event such provision conflicts with the available
reinsurance arrangements of the issuers of such policy, such provision shall not
be included in the related insurance policy. Each Owner will be required to
ensure, inter alia, that 7 Business Days prior written notice be given to the
Trustees and to the Collateral Agent prior to the cancellation or modification
of any insurance.

INSURANCE PROCEEDS

         The proceeds of any insurances or entries referred to in the Mortgage
will be applied as follows:

         until the occurrence of an Event of Default:


                                      -130-
<PAGE>

         (i) any claim under any such insurance will be deposited in the
Casualty Account and will be applied by the Collateral Agent pursuant to the
terms of the Intercreditor Agreement; and

         (ii) any claim in respect of protection and indemnity insurance shall
be paid directly to the person, firm or company to which the liability covered
by such insurance was incurred, or to the applicable Owner in reimbursement of
moneys expended by it in satisfaction of such liability.

         Upon the occurrence of an Event of Default, except as provided above,
any claim under any such insurance and entry (other than in respect of actual,
constructive, arranged or compromised total loss) will be deposited in the
Termination Account, and will be applied by the Collateral Agent
pursuant to the terms of the Intercreditor Agreement.

         No Owner will alter so as to in any way restrict the cover of any
insurances or entries referred to in its Mortgage, except to the extent
expressly permitted by the Collateral Agent.

EVENTS OF DEFAULT UNDER THE MORTGAGE

         The following constitute Events of Default under the Mortgages:

         (i) an Event of Default under the Indentures or the Letter of Credit
Reimbursement Agreement;

         (ii) default by the applicable Owner in the payment of any sums payable
under its Mortgage to the Collateral Agent (other than payments due under the
Indentures) continuing for two Business
Days after the receipt of notice of such failure to pay;

         (iii) default by the applicable Owner in any material respect in the
performance, or breach in any material respect of any covenant of its Owner
under its Mortgage or if any representation or warranty of such Owner made in
such Mortgage or in any certificate or other writing delivered pursuant thereto
or in connection therewith with respect to or affecting the related Vessel
proves to have been inaccurate in any material respect as of the time when the
same shall have been made, and, if such breach or default or inaccuracy is
curable, continuance of such default or breach or inaccuracy for a period of 10
days after receipt of written notice thereof from the Collateral Agent or any
Trustee or the Letter of Credit Issuer;

         (iv) entry of a decree or order for relief by a court having
jurisdiction in the premises in respect of the applicable Owner in any
involuntary case under any applicable federal or state bankruptcy, insolvency,
or other similar law now or hereafter in effect, or appointment of a receiver,
liquidator, assignee, custodian, trustee, or sequestrator (or other similar
official) for such Owner or for any substantial part of its property, or the
ordering, winding up or liquidation of its respective affairs, and the
continuance of any such decree or order unstayed and in effect for a period of
90 consecutive days;

         (v) commencement by the applicable Owner of a voluntary case under any
applicable federal or state bankruptcy, insolvency, or other similar law now or
hereafter in effect in any jurisdiction, or the consent by such Owner to the
appointment of or taking possession by a receiver, liquidator,


                                      -131-
<PAGE>

assignee, custodian, trustee or sequestrator (or other similar official) of such
Owner or any substantial part of its property, or the making by such Owner of
any general assignment for the benefit of creditors, or the failure by such
Owner generally to pay its debts as they become due, or the taking of action by
the Owner in furtherance of any such action;

         (vi) any Vessel is deemed a Total Loss and the Insurance Proceeds
thereof have not been received by the Collateral Agent within 90 days after the
date on which such Vessel was deemed a Total Loss; or

         (vii) a Lien other than a Permitted Lien is placed on any Vessel.

REMEDIES

         In the event that any one or more Events of Default has occurred and is
continuing, then, in each and every such case the Collateral Agent, will have
the right to:

         (i) in the event the related Trustee or the Letter of Credit Issuer has
declared immediately due and payable all amounts owing under the Notes and the
Letter of Credit Reimbursement Agreement (in which case all of the same shall be
immediately due), bring suit at law, in equity or in admiralty, as it may be
advised, to recover judgment for such amounts and collect the same out of any
and all property of the applicable Owner whether covered by the related Mortgage
or otherwise;

         (ii) exercise all of the rights and remedies in foreclosure and
otherwise given to mortgagees by provisions of applicable law;

         (iii) take and enter into possession of the applicable Vessel, at any
time, wherever the same may be, without court decision or other legal process
and without being responsible for loss or damage and the Collateral Agent may,
without being responsible for loss or damage, hold, lay-up, lease, charter,
operate or otherwise use such Vessel for such time and upon such terms as it may
deem to be for its best advantage, and demand, collect and retain all hire,
freights, earnings, issues, revenues, income, profits, return premiums, salvage
awards or recoveries, recoveries in general average, and all other sums due or
to become due in respect of such Vessel or in respect of any insurance thereon
from any person whomsoever, accounting only for the net profits, if any, arising
from such use of such Vessel and charging upon all receipts from use of the
Vessel or from the sale thereof by court proceedings or by private sale all
costs, expenses, charges, damages or losses by reason of such use, and if at any
time the Collateral Agent avails itself of the right given to it to take the
Vessel: (i) the Collateral Agent will have the right to dock the Vessel for a
reasonable time at any dock, pier or other premises of the Owner without charge,
or to dock her at any other place at the cost and expense of the Owner; and (ii)
the Collateral Agent will have the right to require the Owner to deliver, and
the Owner will on demand, at its own cost and expense, deliver to the Collateral
Agent the Vessel as demanded; and (iii) the Owner will irrevocably instruct the
master of the Vessel so long as the Mortgage is outstanding to deliver the
Vessel to the Collateral Agent as demanded; and

         (iv) sell the applicable Vessel or any share therein with or without
the benefit of any charterparty or other engagement by public auction or private
contract without legal process at any


                                      -132-
<PAGE>

place in the world and upon such terms as the Collateral Agent in its absolute
discretion may determine with power to postpone any such sale and without being
answerable for any loss occasioned by such sale or resulting from the
postponement thereof and at any such public auction the Collateral Agent may
become the purchaser and shall have the right to set off the purchase price
against the Notes. Any sale of such Vessel or any shares therein made by the
Collateral Agent in pursuance of the applicable Mortgage will operate to divest
all title, right and interest of any nature whatsoever of the applicable Owner
therein and thereto and shall bar such Owner, its successors and assigns, and
all persons claiming by, through or under them. Upon any such sale, the
purchaser will not be bound to see or inquire whether the Collateral Agent's
power of sale has risen in the manner provided by such Mortgage and the sale
will be within the power of the Collateral Agent and the receipt of the
Collateral Agent of the purchase money will effectively discharge the purchaser,
who will not be concerned with the manner of application of the proceeds of sale
or be in any way answerable or otherwise liable therefor.

         Each of the Vessels will be registered under the laws of the Republic
of Liberia. The Mortgages on the Vessels will be preferred mortgage liens under
Liberian maritime law. Liberian law provides that such mortgages may be enforced
by the mortgagee in a proceeding substantially identical to a suit in rem in
admiralty in a proceeding against a vessel covered by such mortgage.

         The priority with respect to sale proceeds that such a mortgage would
have vis-a-vis the claims of other lien creditors in an enforcement proceeding
is generally determined by, and will vary in accordance with, the law of the
country where the proceeding is brought. Liberian maritime law provides that a
"preferred mortgage lien" is prior to all claims, other than the following:

                  (i) liens against the vessel arising prior in time to the
         recording of the preferred mortgage;

                  (ii) liens for damages arising out of tort;

                  (iii) liens for unpaid vessel tonnage taxes and annual fees
         and penalties payable under the Liberian Maritime Regulations;

                  (iv) liens for crew wages;

                  (v) liens for general average;

                  (vi) liens for salvage; and

                  (vii) liens for expenses and fees allowed and costs imposed by
         courts of competent jurisdiction.

         Liberian ship mortgages may be enforced against a vessel that is
physically present in the United States, but the claim under the mortgage would
rank below certain preferred maritime liens as defined under the laws of the
United States, including those for supplies and necessaries provided in the
United States. Since the Vessels will be trading throughout the world, there can
be no assurance that, if enforcement proceedings are commenced against a Vessel,
such Vessel will be


                                      -133-
<PAGE>

located in a jurisdiction having the same procedures and lien priorities as
Liberia or the United States. Other jurisdictions may provide no legal remedy at
all for the enforcement of the Mortgages, or may provide a remedy that is
dependent on court proceedings so expensive and time consuming as to be
impractical. Furthermore, certain jurisdictions, unlike Liberia or the United
States, may not permit a Vessel to be sold prior to entry of a judgment,
entailing a long waiting time that could result in increased custodial costs,
deterioration in the condition of the Vessel and substantial reduction in her
value.

         Since the Notes are also secured by a pledge by the Issuer of all the
stock of the Owners, enforcement of this pledge, including foreclosure, may
provide in effect an alternative method to transfer control over a Vessel and
mitigate against a substantial reduction in her value.

             MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

                               THE EXCHANGE OFFER

         The following disclosure summarizes the material federal income tax
consequences under the Internal Revenue Code of 1986 (the "Code") expected to
result to Holders whose Existing Notes are exchanged for Exchange Notes in the
Exchange Offer. This discussion has been prepared with the advice of Thacher
Proffitt & Wood, counsel to the Company, and is based upon the provisions of the
Code, the Treasury regulations thereunder, and published rulings and court
decisions in effect as of the date hereof, all of which authorities are subject
to change or differing interpretations, which could apply retroactively. The
disclosure below does not purport to deal with federal income tax consequences
applicable to all categories of investors and is directed solely to holders that
hold the Notes as capital assets within the meaning of Section 1221 of the Code,
and acquire such Notes for investment and not as a dealer or for resale. This
disclosure is not intended to address every aspect of the federal income tax
laws that may be relevant to holders in light of their particular investment
circumstances or to certain types of holders subject to special treatment under
the federal income tax laws such as banks, insurance Companies, holders that
will hold the Notes as a position in a "straddle" for tax purposes or as a part
of a "synthetic security" or "conversion transaction" or other integrated
investment comprised of the Notes and one or more other investments, holders who
own or will own directly, indirectly or by attribution including stock
attribution resulting from ownership of the Warrants) 10.0% or more (by voting
power) of Holdings Common Stock or holders that have a functional currency other
than the U.S. dollar. Prospective investors should note that no rulings have
been or will be sought from the Internal Revenue Service (the "IRS") with
respect to any of the federal income tax consequences discussed below, and no
assurance can be given that the IRS will not take contrary positions. Holders
and preparers of tax returns should be aware that under applicable Treasury
regulations a provider of advice on specific issues of law is not considered an
income tax return preparer unless the advice is (i) given with respect to events
that have occurred at the time the advice is rendered and is not given with
respect to the consequences of contemplated actions, and (ii) directly relevant
to the determination of an entry on a tax return. Accordingly, holders should
consult their own tax advisors and tax return preparers regarding the
preparation of any item on a tax return.


                                      -134-
<PAGE>

         All investors also should consult their own tax advisors in determining
the federal, state, local, foreign and any other tax consequences to them of an
investment in the Notes and the purchase, ownership and disposition thereof.

         The exchange of Existing Notes for Exchange Notes will be treated as a
"non-event" for federal income tax purposes because the Exchange Notes will not
be considered to differ materially in kind or extent from the Existing Notes. As
a result, no material federal income tax consequences will result to Holders
exchanging Existing Notes for Exchange Notes.

                            UNITS, NOTES AND WARRANTS

         The following disclosure summarizes the material federal income tax
consequences under the Internal Revenue Code of 1986 (the "Code") of the
purchase, ownership and disposition of the Notes, Units, Warrants and Holdings
Common Stock obtained upon exercise of the Warrants offered on the Original
Closing Date to initial purchasers of Notes or Units that, except as noted
below, are United States persons (as defined below). This disclosure has been
prepared with the advice of Thacher Proffitt & Wood, counsel to the Company, and
is based upon the provisions of the Code, the Treasury regulations thereunder,
and published rulings and court decisions in effect as of the date hereof, all
of which authorities are subject to change or differing interpretations, which
could apply retroactively. The disclosure below does not purport to deal with
federal income tax consequences applicable to all categories of investors and is
directed solely to holders that hold the Notes, Units, Warrants or shares of
Holdings Common Stock as capital assets within the meaning of Section 1221 of
the Code, and acquire such Notes, Units, Warrants or shares of Holdings Common
Stock for investment and not as a dealer or for resale. This disclosure is not
intended to address every aspect of the federal income tax laws that may be
relevant to holders in light of their particular investment circumstances or to
certain types of holders subject to special treatment under the federal income
tax laws such as banks, insurance companies, holders that will hold the Notes,
Units, Warrants or shares of Holdings Common Stock as a position in a "straddle"
for tax purposes or as a part of a "synthetic security" or "conversion
transaction" or other integrated investment comprised of the Notes and one or
more other investments, holders who own or will own directly, indirectly or by
attribution (including stock attribution resulting from ownership of the
Warrants) 10.0% or more (by voting power) of Holdings Common Stock or holders
that have a functional currency other than the U.S. dollar. Prospective
investors should note that no rulings have been or will be sought from the
Internal Revenue Service (the "IRS") with respect to any of the federal income
tax consequences discussed below, and no assurance can be given that the IRS
will not take contrary positions. Holders and preparers of tax returns should be
aware that under applicable Treasury regulations a provider of advice on
specific issues of law is not considered an income tax return preparer unless
the advice is (i) given with respect to events that have occurred at the time
the advice is rendered and is not given with respect to the consequences of
contemplated actions, and (ii) directly relevant to the determination of an
entry on a tax return. Accordingly, holders should consult their own tax
advisors and tax return preparers regarding the preparation of any item on a tax
return, even where the anticipated tax treatment has been discussed herein.

         All investors also should consult their own tax advisors in determining
the federal, state, local, foreign and any other tax consequences to them of an
investment in the Notes, Units, Warrants or shares of Holdings Common Stock and
the purchase, ownership and disposition thereof.


                                      -135-
<PAGE>

         Upon the issuance of the Existing Notes, Thacher Proffitt & Wood,
counsel to the Issuer, delivered its opinion generally to the effect that, based
upon the application of existing law, and assuming compliance with all
provisions of the Indentures and other relevant documents, and the facts set
forth in the Confidential Offering Circular, dated July 31, 1997 related to the
Existing Notes and Warrants, the First Priority Notes will, and the Second
Priority Notes should, be characterized as indebtedness of the Issuer for
federal income tax purposes. Holders of Notes should recognize, however, that
there is some uncertainty regarding the appropriate characterization of
instruments such as the Notes. It is possible that the IRS might contend that
the First Priority Notes and/or the Second Priority Notes should be treated not
as debt of the Issuer but as equity interests in the Issuer. Any such
recharacterization might result in material adverse consequences to United
States persons holding such Notes, including those described below under
"--HOLDINGS COMMON STOCK." The balance of this discussion assumes that the Notes
are treated as indebtedness for federal income tax purposes.

UNITS

         Because the original purchasers of the Second Priority Notes also will
acquire Warrants, each Second Priority Note likely will be treated for federal
income tax purposes as having been issued as part of an "investment unit"
consisting of the Second Priority Note and associated Warrant. The issue price
of an investment unit consisting of the Second Priority Note and associated
Warrant will be the first price at which a substantial amount of Units are sold
to the public for money (excluding sales to bond houses, brokers, or similar
persons or organizations acting in the capacity of underwriters, placement
agents or wholesalers). The issue price of an investment unit is allocated
between its component parts based on their relative fair market values. The
Issuer and Holdings have allocated the issue price of a Unit between the Second
Priority Note and the associated Warrant in accordance with the Issuer's
determination of their relative fair market values on the Original Closing Date.
The Issuer will use that allocation to determine the issue price of the Second
Priority Notes and the holder's tax basis in the Warrants. Although the Issuer's
allocation is not binding on the IRS, a holder of a Unit must use the Issuer's
allocation unless the holder discloses on its federal income tax return for the
year in which the Unit was acquired that it plans to use an allocation that is
inconsistent with the Issuer's allocation.

UNITED STATES PERSONS

         The following discussion is limited to the United States federal income
tax consequences relevant to a holder of Notes, Units, Warrants and Holdings
Common Stock that is a United States person. For those purposes, a "United
States person" means a citizen or resident of the United
States,
a corporation, partnership or other entity created or organized in, or under the
laws of, the United States or any political subdivision thereof (except, in the
case of a partnership, to the extent provided in regulations), an estate whose
income is subject to United States federal income tax regardless of its source,
or a trust other than a foreign trust within the meaning of Section 7701(a)(31)
of the Code. Holders who are not United States persons should consult their own
tax advisors regarding the tax consequences of purchasing, owning or disposing
of a Note, Unit, Warrant or share of Holdings Common Stock.

NOTES


                                      -136-
<PAGE>

         ORIGINAL ISSUE DISCOUNT

         The Existing Notes were issued with "original issue discount" for
federal income tax purposes. A Holder of a Note generally is required to include
original issue discount in gross income as it accrues, regardless of the
holder's method of accounting for federal income tax purposes. Accordingly, each
holder will be required to include amounts in gross income without regard to
when the cash to which such income is attributable is received.

         Because the Issuer is required, to the extent of Available Cash, to
offer to purchase Notes on each Available Cash Payment Date at a price equal to
102% of a Note's principal amount, although the matter is not free from doubt,
Treasury regulations regarding contingent payment debt instruments likely will
apply to the Notes. It is not altogether clear how the contingent payment rules
apply to a debt instrument the payments on which may be received at the option
of a holder. The Issuer will assume for purposes of those rules that an option
that increases a holder's yield (such as the Available Cash Offer) will be
deemed exercised, and that a non-exercise of such option will result in
adjustments as described below.

         In general, under the contingent payment rules, the Issuer is required
to construct a projected payment schedule for the Notes. A holder generally will
recognize all interest income with respect to a Note on a constant yield basis
based on that projected payment schedule (but would not recognize ordinary
income upon receipt of cash payments denominated as interest), subject to
certain adjustments if actual contingent payments differ from those projected.
Such interest is treated as "original issue discount."

         The projected payment schedule includes each noncontingent payment and
a projection of the amount and timing of each contingent payment on the Notes as
of the Original Closing Date, assuming exercise of options by a holder that
increase such holder's yield (such as the Available Cash Offer). The projected
payment schedule must produce the "comparable yield," which is the yield at
which the Issuer would issue a fixed rate debt instrument with terms and
conditions similar to those of the Notes. The amount of interest that accrues in
each accrual period is the product of the "comparable yield" (adjusted for the
length of the accrual period) and the Note's "adjusted issue price" at the
beginning of each accrual period. The adjusted issue price of a Note is equal to
its issue price, increased by interest previously accrued on the Note
(determined without adjustments), and decreased by the amount of any
noncontingent payments and the projected amount of any contingent payments
previously made on the Note. The issue price of a First Priority Note is the
first price at which a substantial amount of such Notes was sold to the public
for money (excluding sales to bond houses, brokers, or similar persons or
organizations acting in the capacity of underwriters, placement agents or
wholesalers). The issue price of a Second Priority Note is equal to that portion
of the issue price of the Unit allocable to the Second Priority Note as
described above.

         Except for adjustments made for differences between actual and
projected payments, the amount of interest included in income by a holder of a
Note is the sum of the "daily portions" of interest income with respect to the
Note for each day during the taxable year (or portion thereof) on which such
holder held such Note. The "daily portions" of interest income are determined by
allocating to each day in an accrual period the ratable portion of the interest
that accrues in that accrual period. If the total actual payments exceed the
total projected payment in a tax year (a "net


                                      -137-
<PAGE>

positive adjustment"), a holder generally will be required to treat such excess
as additional interest includible in gross income for such tax year. If the
total actual payments are less than the total projected payments in a tax year
(a "net negative adjustment"), a holder will be required to reduce the amount of
interest income that it would otherwise account for by the amount of such
difference.
If the net negative adjustment exceeds the amount of interest income that the
holder would otherwise account for, such excess will be treated as an ordinary
loss to the extent that the holder's total interest inclusions with respect to
the Note exceed the total net negative adjustments treated as ordinary loss on
the Note in prior taxable years. Any remaining excess will be a "negative
adjustment carryforward" and treated as a negative adjustment in the succeeding
tax year. If a Note is sold, retired or otherwise disposed of in a taxable
transaction, any negative adjustment carryforward from the prior year will
reduce the holder's amount realized on the sale, retirement or disposition.
Thus, because the yield to maturity of the Notes will be determined for federal
income tax purposes by assuming that the projected payments will be made on
specific dates, a holder of Notes may be required to include amounts in income
prior to the receipt of cash payments attributable to such income.

         The Issuer will provide to holders the projected payment schedule for
the Notes. The payment amounts, timing thereof, and yield set forth on the
projected payment schedule are for federal income tax purposes only and are not
assurances by the Issuer with respect to any aspect of the Notes. A holder
generally will be bound by the projected payment schedule. The IRS, however,
will not respect the projected payment schedule if it determines such schedule
to be unreasonable.

         Holders are strongly urged to consult their tax advisors with respect
to the application of the contingent payment rules described above to the Notes.

         SALE, RETIREMENT OR OTHER TAXABLE DISPOSITION

         In general, a holder of a Note will recognize gain or loss upon the
sale, retirement or other taxable disposition of such Note in an amount equal to
the difference between (a) the amount of cash and the fair market value of other
property received in exchange therefor and (b) the holder's adjusted
tax basis in such Note.

         A holder's tax basis in a Note generally will be equal to the price
paid for such Note, increased by the amount of interest previously accrued on
the Note (determined without adjustments), and decreased by the amount of any
noncontingent payments and the projected amount
of any contingent payments previously made on the Note.

         If a Note is sold or otherwise disposed of when there are remaining
contingent payments due under the projected payment schedule, then any gain
recognized upon such sale or other disposition will be ordinary interest income,
while any loss recognized will be ordinary loss to the extent that the holder's
total interest inclusions on a Note exceed the total net negative adjustments on
the Note that the holder took into account as ordinary loss under the rules
described above, and any additional loss will generally be a capital loss. If,
however, a Note is sold or otherwise disposed of after there are no remaining
contingent payments due on the Notes under the projected payment schedule, the
resulting gain or loss generally will be capital gain or loss and will be
long-term capital gain or loss if the Note had been held for more than one year.
Any such capital gain realized by an individual,


                                      -138-
<PAGE>

estate or trust will qualify for the 20% maximum tax (10% in the case of such a
taxpayer in the 15% ordinary income tax bracket) on capital gains if the Note
sold or otherwise disposed of was held for at least 18 months, and for the 28%
maximum tax on capital gains if such Note was held for more than one year and
less than 18 months.

         Holders should be aware that the resale of a Note may be affected by
the market discount rules of the Code under which a subsequent purchaser of a
Note acquiring such Note at a market discount generally would be required to
include as ordinary income a portion of the gain realized upon the disposition
or retirement of such Note, to the extent of the market discount that has
accrued while the debt instrument was held by such holder.

FOREIGN TAX CREDIT CONSIDERATIONS--EFFECT OF ISLE OF MAN WITHHOLDING TAXES

         For purposes of the U.S. foreign tax credit limitations, original issue
discount with respect to the Notes will be foreign source income. In addition,
in the event that cash interest payments on the Notes become subject to Isle of
Man withholding taxes and the Issuer accordingly is required to pay Additional
Amounts, a holder of a Note will be treated as actually receiving any amount
withheld by the Issuer from a cash interest payment with respect to a Note and
then as having paid over such amount to the Isle of Man taxing authorities. As a
result, the amount includible in the income of a holder for U.S. federal income
tax purposes may be greater than the amount actually received by such holder
from the Issuer with respect to such payment. Subject to certain limitations, a
holder of a Note generally will be entitled to a credit against its U.S. federal
income tax liability, or deduction in computing its U.S. federal taxable income,
in respect of Isle of Man income taxes withheld by the Issuer. A holder of Notes
should consult his own tax advisor as to the consequences of Isle of Man
withholding taxes and the availability of a foreign tax credit or deduction.

WARRANTS

         The exercise of a Warrant will not result in a taxable event to the
holder of the Warrant. Upon such exercise, the holder's adjusted tax basis in
the Holdings Common Stock obtained will be equal to the sum of such holder's
adjusted tax basis in the Warrant (described above) and the exercise price of
the Warrant; the holder's holding period with respect to such Holdings Common
Stock will commence on the day after the date of exercise.

         If a Warrant expires without being exercised, the holder will recognize
a loss in an amount equal to its tax basis in the Warrant. Such loss will be a
capital loss if the Holdings Common Stock to which the Warrants relate would
have been a capital asset in the hands of the Warrant holder, and such capital
loss will be a long-term capital loss if the Warrant was held for more than one
year at the time of the lapse.

         Upon the sale or other taxable disposition of a Warrant, a holder will
recognize gain or loss for federal income tax purposes in an amount equal to the
difference between (a) the amount of cash and the fair market value of property
received therefor and (b) the holder's adjusted tax basis in the Warrant. A
holder's initial tax basis in a Warrant will be that portion of the issue price
of the Units allocable to the Warrant, as described above, and subject to
adjustment in the events described above. Such gain or loss will be capital gain
or loss if the Holdings Common Stock to which the


                                      -139-
<PAGE>

Warrants relate would be a capital asset in the hands of the Warrant holder. Any
such capital gain or loss will be long-term capital gain or loss if the Warrant
was held for more than one year at the time of the sale or exchange and
otherwise will be a short-term capital gain or loss. Any such capital gain
realized by an individual, estate or trust will qualify for the 20% maximum tax
(10% in the case of such a taxpayer in the 15% ordinary income tax bracket) on
capital gains if the Warrant sold or otherwise disposed of was held for at least
18 months, and for the 28% maximum tax on capital gains if such Warrant was held
for more than one year and less than 18 months.

         It is possible that the Warrants may be deemed to have been exercised
for tax purposes on the date on which they first become exercisable or possibly
on the date issued, regardless of whether they are actually exercised on the
date on which they are first exercisable. As a result, it is possible that the
holding period of a share of Holdings Common Stock may be deemed to have begun
on the date on which the Warrants first become exercisable or possibly on the
date issued.

         Under current provisions of the Code relating to holders of stock in a
"passive foreign investment company," holders of options to acquire such stock
are considered to own such stock for purposes of certain of those provisions.
Accordingly, the consequences described in "Passive Foreign Income Company
Status" below generally apply to the holder of a Warrant upon receipt of such
Warrant, except to the extent described below.

         Adjustments to the number of shares of Holdings Common Stock
purchasable upon exercise of the Warrants, or the failure to make adjustments,
may in certain circumstances result in the receipt of taxable constructive
dividends by the holder resulting in ordinary income to the extent of Holdings'
current and accumulated earnings and profits (as determined for U.S. federal
income tax purposes). In such event the holder's tax basis in the Warrants would
be increased by an amount equal to the constructive dividend.

HOLDINGS COMMON STOCK

         DISTRIBUTIONS

         Distributions of cash or property with respect to the Holdings Common
Stock will constitute ordinary dividend income to the extent of Holdings'
current and accumulated earnings and profits (as determined for U.S. federal
income tax purposes) and will be treated as foreign source dividend income. Any
distributions in excess of such earnings and profits will constitute a
nontaxable return of capital and reduce the holder's tax basis in such Holdings
Common Stock. To the extent such distributions exceed a holder's tax basis in
Holdings Common Stock, such excess will constitute capital gain. The dividend
will not be eligible for the dividends received deduction allowed to United
States corporations. Special rules apply for purposes of determining the foreign
tax credit available to a United States corporation which controls 10% or more
of the voting shares of Holdings.

         SALE OR OTHER TAXABLE DISPOSITION

         A holder will, upon the sale, redemption or other taxable disposition
of Holdings Common Stock, recognize gain or loss for federal income tax purposes
in an amount equal to the difference between (a) the amount of cash and the fair
market value of property received therefor and (b) the


                                      -140-
<PAGE>

holder's tax basis in the Holdings Common Stock. Except as described below under
"Passive Foreign Investment Company Status," such gain or loss will be capital
gain or loss if the Holdings Common Stock were a capital asset in the hands of
the holder. Any such capital gain realized by an individual, estate or trust
will qualify for the 20% maximum tax (10% in the case of such a taxpayer in the
15% ordinary income tax bracket) on capital gains if the Holdings Common Stock
sold or otherwise disposed of was held for at least 18 months, and for the 28%
maximum tax on capital gains if such share of Holdings Common Stock was held for
more than one year and less than 18 months and will be long-term if the Holdings
Common Stock were held for more than one year. Any such gain generally will not
be treated as foreign source income.

         If a holder receives any foreign currency on the sale or other taxable
disposition of Holdings Common Stock, the holder may recognize ordinary gain or
loss as a result of currency fluctuations between the date of the sale and the
date the sale proceeds are converted into U.S. dollars.

         PASSIVE FOREIGN INVESTMENT COMPANY STATUS

         Because Holdings will receive (or be deemed to receive) rental income
and other passive income, Holdings may be a passive foreign investment company
("PFIC") for federal income tax purposes. Holdings will be a PFIC if either 75%
or more of its gross income in a tax year is passive income or the average
percentage of its assets (by value) which produce or are held for the
production of passive income is at least 50%.

         A determination as to PFIC status is made annually (although an initial
determination that Holdings is a PFIC generally will apply for subsequent years
(whether or not Holdings meets the PFIC test in those years)) with respect to a
holder owning Holdings stock who does not make the qualified electing fund
("QEF") election with respect to the first year it holds or is deemed to hold
Holdings stock and for which Holdings is determined to be a PFIC.

         Whether Holdings is a PFIC in any year and the tax consequences
relating to PFIC status will depend on the composition of the income and assets
of Holdings, which may vary each year. Holdings will monitor its status and
will, promptly following the end of any taxable year for which it determines it
was a PFIC, notify holders of such status and comply with the reporting and
other requirements necessary for holders to make a QEF election (described
below).

         If Holdings is a PFIC, the direct and certain indirect holders holding
Holdings Common Stock must either (i) make a QEF election and report currently
their pro rata share of Holdings' ordinary earnings and net capital gain even if
they do not receive distributions from Holdings, or (ii) upon disposition of
Holdings Common Stock or Warrants or receipt of an "excess distribution" (as
defined in the Code), be subject to tax generally as if the gain or distribution
were ordinary income earned ratably over the period in which the Holdings Common
Stock or Warrant was held (including payment of an interest charge on the
deferred tax), and face other adverse tax consequences. While it is unclear,
holders of Warrants should be aware that it is likely that the QEF election will
be unavailable to Warrant holders.

         If Holdings determines that it is a PFIC at any time and so notifies
holders, it is strongly urged that each holder of Holdings Common Stock or
Warrants make a QEF election in accordance


                                      -141-
<PAGE>

with the procedure described in the following paragraph. Any such notification
from Holdings also would include a detailed explanation as to how to make a QEF
election. If such election is made, the holder would be required to include in
income the holder's pro rata share of Holdings' ordinary earnings and net
capital gain during the PFIC year. As stated above, it is not entirely clear if
a QEF election is available to holders of Warrants. If the IRS successfully
claims that a holder of Warrants could not make a QEF election, or if a holder
of Holdings Common Stock or Warrants fails to make a QEF election after
receiving a notification from Holdings that it is or was a PFIC, the holder will
face severe adverse tax consequences described under (ii) of the preceding
paragraph.

         The QEF election is made on a shareholder-by-shareholder basis. Each
holder should consult with its own tax adviser to decide whether to make the QEF
election. This election is made by attaching the shareholder election statement,
the PFIC annual information statement and Form 8621 to such holder's timely
filed United States federal income tax return with a copy of the shareholder
election statement being sent to the Internal Revenue Service Center, P.O. Box
21088, Philadelphia, Pennsylvania 19114. If Holdings is (or under the
circumstances described above, was) a PFIC, copies of the Form 8621 must also be
filed every year, both with such tax return and with the IRS Center in
Philadelphia, whether or not the QEF election is made. Holdings will supply the
PFIC annual information statement to any holder of Holdings Common Stock or
Warrant or former holder of Holdings Common Stock or Warrant who requests it and
to all shareholders of record who are holders at any time in any PFIC year.


LIQUIDATED DAMAGES

         The Issuer intends to take the position that the additional payments
described above under "Description of the Exchange Notes--Registered Exchange
Offer; Registration Rights" will be taxable to a holder as ordinary income in
accordance with such Holder's method of accounting for tax purposes. The IRS,
however, may take a different position, which could affect the timing of both a
Holder's income and the timing of the Issuer's deduction with respect to such
additional payments.

NON-U.S. PERSONS

         The following discussion is limited to the United States federal income
tax consequences relevant to a holder of a Unit, Note, Warrant or share of
Holdings Common Stock that is not a United States person (a "non-U.S. person").

         NOTES

         In general, payments of principal, premium (if any) and interest
(including original issue discount) on the Notes will not be subject to federal
income tax, including withholding tax, if paid to a non-U.S. person, unless, in
the case of interest (including original issue discount) the non-U.S. person is
(i) a corporation that is an insurance company carrying on a U.S. trade or
business to which the interest (including original issue discount) is
attributable within the meaning of the Code, or (ii) the individual or
corporation has an office or other fixed place of business in the United States
to which the interest is attributable, and the interest either is derived in the
active conduct of a banking, financing or similar business within the United
States or is received by a corporation, the


                                      -142-
<PAGE>

principal business of which is trading in stock or securities for its own
account. Even if (i) or (ii) of the preceding sentence applies to a non-U.S.
person, the exchange of Existing Notes for Exchange Notes pursuant to the
Registered Exchange Offer will not constitute a taxable exchange. See
"--EXCHANGE OFFER" above.

         Gain realized on the sale or retirement of Notes by a non-U.S. person
will not be subject to federal income tax, including withholding tax, unless (i)
the gain is effectively connected with the conduct of a trade or business within
the United States or (ii) in the case of an individual, the holder has been
present in the United States for 183 days or more during the taxable year of the
sale or retirement and certain other conditions are satisfied.

WARRANTS AND HOLDINGS COMMON STOCK

         Distributions by Holdings to a non-U.S. person of a Warrant or share of
Holdings Common Stock would be subject to withholding of federal income tax only
if 25% or more of the gross income of Holdings (from all sources of the
three-year period ending with the taxable year preceding the declaration of the
dividend (the "Testing Period")) was effectively connected with the conduct of a
trade or business in the United States by Holdings. Holdings does not anticipate
that 25% or more of its gross income will be effectively connected with the
conduct of a trade or business in the United States by Holdings, and
accordingly, Holdings anticipates that dividends paid to non-U.S. persons will
not be subject to withholding of federal income tax.

         Gain realized on the sale or other disposition of Warrants or Holdings
Common Stock by a non-U.S. person will not be subject to federal income tax,
including withholding tax, unless (i) the gain is effectively connected with the
conduct of a trade or business within the United States or (ii) in the case of
an individual, the holder has been present in the United States for 183 days or
more during the taxable year of the sale or retirement and certain other
conditions are satisfied.

STATE, LOCAL, FOREIGN AND OTHER TAXES

         Investors should consult their own tax advisors regarding whether the
purchase of the Exchange Notes, Units, Warrants or shares of Holdings Common
Stock, either alone or in conjunction with an investor's other activities, may
subject an investor to any state or local taxes, or to taxes imposed by any
taxing jurisdiction outside the United States, based on an assertion that the
investor is either "doing business" in, or deriving income from a source located
in, any state, local or foreign jurisdiction, including any such assertion
arising from the presence, use, trading or operation of any of the Vessels in
such jurisdiction or any activities in such jurisdiction of an Owner or any
other person. Additionally, potential investors should consider the state,
local, foreign and other tax consequences of purchasing, owning or disposing of
an Exchange Note, Unit, Warrant or share of Holdings Common Stock. State, local
and foreign tax law may differ substantially from the corresponding federal tax
law, and the foregoing discussion does not purport to describe any aspect of the
tax laws of any state or other jurisdiction. Accordingly, potential investors
should consult their own tax advisors with regard to such matters.

INFORMATION REPORTING AND BACKUP WITHHOLDING


                                      -143-
<PAGE>

         The Issuer will provide annual information statements to holders of the
Exchange Notes and information returns to the IRS regarding the amount of
original issue discount that accrued on the
Exchange Notes during the past year.

         A holder of an Exchange Note or share of Holdings Common Stock may be
subject to backup withholding at the rate of 31.0% with respect to original
issue discount and proceeds from the sale, exchange, redemption or retirement of
the Exchange Note or share of Holdings Common Stock unless such holder (i) is a
corporation or falls within certain other exempt categories and, when required,
demonstrates such fact, or (ii) provides a correct taxpayer identification
number, certifies as to no loss of exemption from backup withholding and
otherwise complies with applicable requirements of the backup withholding rules.
Any amount paid as backup withholding would be creditable against such holder's
United States federal income tax liability. A holder who does not provide a
correct taxpayer identification number may be subject to penalties imposed by
the Code.

UNITED STATES TAXATION OF THE COMPANY

         U.S. TAXATION OF OPERATING INCOME. Unless exempt from U.S. taxation
under the rules discussed below, a non-U.S. corporation is subject to U.S.
federal income taxation in respect of any income that is derived from the use of
vessels, from the hiring or leasing of vessels for use on a time, voyage or
bareboat charter basis, or from the performance of services directly related to
such use ("Shipping Income"), to the extent that such Shipping Income is derived
from sources within the United States. For these purposes, 50% of Shipping
Income that is attributable to transportation that begins or ends (but that does
not both begin and end) in the United States constitutes income from sources
within the United States ("50% U.S.-source Shipping Income"). The tax on
non-exempt 50% U.S.-source Shipping Income is 4% of the amount of such income
not reduced by any deductions.

         A foreign corporation, such as the Company, which does not maintain an
office or other fixed place of business within the United States is not subject
to United States taxation with respect to Shipping Income that is not considered
to be from sources within the United States (such as income attributable to
transportation that begins and ends outside of the United States and 50% of the
Shipping Income that is attributable to transportation that begins or ends (but
that does not both begin and end) in the United States).

         The Vessels will be operated in various parts of the world and, in
part, may be involved in transportation of cargoes that begins or ends (but that
does not both begin and end) in U.S.
ports.

         EXEMPTION OF OPERATING INCOME FROM U.S. TAXATION. Pursuant to Section
883 of the Code, the Company will be exempt from U.S. taxation of its 50%
U.S.-source Shipping Income, if both (i) the Company is organized in a foreign
country that grants an equivalent exemption to corporations organized in the
United States (the "Equivalent Exemption Requirement"), and (ii) either (A) more
than 50% of the value of the Company's shares is owned, directly or indirectly,
by individuals who are "residents" of such country or of another foreign country
that grants an equivalent exemption to corporations organized in the United
States (the "50% Ownership Test") or (B) stock of the Company is "primarily and
regularly traded on an established securities market" in such country, in


                                      -144-
<PAGE>

another country that grants an "equivalent exemption" to U.S. corporations, or
in the United States (the "Publicly-Traded Test").

         The Isle of Man, the country in which the Company is incorporated,
grants an "equivalent exemption" to U.S. corporations. Therefore, the Company
will be exempt from U.S. federal income taxation with respect to its 50%
U.S.-source Shipping Income if either the 50% Ownership Test or the
Publicly-Traded Test is met. As of the Original Closing Date, the Company met
the 50% Ownership Test. However, no assurance can be given that the Company will
qualify for the exemption in any future year.

         U.S. TAXATION OF GAIN ON SALE OF VESSELS. Regardless of whether the
Company qualifies for exemption under Section 883 of the Code, the Company will
not be subject to United States taxation with respect to gain realized on sale
of a Vessel, provided that the sale is considered to occur outside of the United
States under United States tax principles. In general, a sale of a Vessel will
be considered to occur outside of the United States for this purpose if title to
the Vessel, and risk of loss with respect to the Vessel, pass to the buyer
outside of the United States. It is expected that any sale of a Vessel will be
considered to occur outside of the United States.

         FIXED PLACE OF BUSINESS WITHIN THE UNITED STATES. In the event that the
Company were considered to maintain an office or other fixed place of business
within the United States, the Company could become subject to the net-basis U.S.
federal corporate income tax, which currently is imposed at rates of up to 35%
on taxable income, and to the 30% "branch profits tax" regime of Section 884 of
the Code with respect to any U.S.-source Shipping Income and gain not in excess
of the "depreciation adjustments," as defined in Section 865 of the Code, on the
sale of a Vessel that has produced such "effectively connected" income. As noted
above, the Company does not expect to have an office or other fixed place of
business within the United States.


                              ERISA CONSIDERATIONS

         Sections 404 and 406 of the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), and Section 4975 of the Code impose restrictions on
the activities of employee benefit plans (as defined in Section 3(3) of ERISA)
and certain other retirement plans and arrangements described in Section
4975(e)(l) of the Code, including individual retirement accounts, individual
retirement annuities and Keogh plans and insurance company separate accounts and
bank collective investment funds, in which such plans, accounts, annuities or
arrangements are invested (each a "Plan").

         Section 404 of ERISA imposes general fiduciary requirements on the
fiduciaries of Plans to which it applies, including requirements of investment
prudence and diversification in managing such a Plan's assets. In addition,
Section 406 of ERISA prohibits Plans to which it applies from engaging in
transactions described in Section 406 of ERISA, and Section 4975 of the Code
imposes excise taxes with respect to transactions described in Section
4975(c)(l) of the Code. The transactions described in Section 406 of ERISA and
Section 4975(c)(l) of the Code are transactions which involve the assets of a
Plan and to which a person related to the Plan is a party. Statutory and
administrative exemptions from such restrictions and taxes are available in
certain cases.


                                      -145-
<PAGE>

         The purchase of Securities by a Plan may be deemed to constitute a
sales transaction between the Plan and the seller of Securities, as well as an
extension of credit by the Plan to the Issuer or the Owners. Either of such
transactions could constitute a prohibited transaction if Holdings, the Issuer
or any of the Owners is a "party in interest" with respect to the Plan for
purposes of Section 406 of ERISA or a "disqualified person" with respect to the
Plan under Section 4975 of the Code. In such a case, the Plan should not
purchase or hold the Securities unless there is in effect a statutory or
administrative prohibited transaction exemption making Section 406 of ERISA and
Section 4975 of the Code inapplicable to such purchase and holding.

         Additional ERISA considerations may apply if the Securities cause the
holders thereof to be deemed to have an equity interest in Holdings, the Issuer
or the Owners for purposes of ERISA. In that event, a Plan's investment in the
Securities may cause the assets of Holdings, the Issuer or the Owners to be
deemed to be assets of the Plan for purposes of Sections 404 and 406 of ERISA
and Section 4975 of the Code. In such event, ERISA's fiduciary standards might
apply to actions involving Holdings, the Issuer's or the Owners' assets, and any
transactions involving Holdings, the Issuer or the Owners, or their respective
assets could be deemed to be transactions to which the restrictions of Section
406 or ERISA and the taxes imposed under Section 4975 of the Code might apply.
Under Section 2510.3-101 of regulations issued by the United States Department
of Labor (the "Regulations"), when a Plan to which the Regulations apply
acquires an equity interest in an entity, the Plan's assets include the
investment in the entity and, with certain exceptions, an undivided interest in
each asset of the entity in which the investment is made. Exceptions contained
in the Regulations provide that a Plan's assets will not include an undivided
interest in each asset of an entity in which it makes an equity investment if:
(1) the entity is an operating company; (2) the equity investment made by the
Plan is either a "publicly-offered security" as defined in the Regulations or a
security issued by an investment company registered under the Investment Company
Act of 1940, as amended; or (3) Benefit Plan Investors do not own 25% or more in
value of any class of equity securities issued by the entity. For this purpose,
"Benefit Plan Investors" include Plans, as well as any "employee benefit plan"
as defined in Section 3(3) of ERISA which is not subject to Title I of ERISA,
such as governmental plans (as defined in Section 3(32) of ERISA) and church
plans (as defined in Section 3(33) of ERISA) which have not made an election
under Section 410(d) of the Code, and any entity whose underlying assets include
Plan assets by reason of a Plan's investment in the entity.

         If the purchase of the Securities results in holders thereof having an
equity interest in Holdings, the Issuer or the Owners for purposes of ERISA,
there is no assurance that any of the exceptions set forth in the Regulations
will apply to the purchase of the Securities offered hereby. Under the terms of
the Regulations, if any person were deemed to hold Plan assets by reason of a
Plan's investment in the Securities, such Plan assets may include an undivided
interest in the Vessels and other property of such person. In such an event, the
Owners, the Trustees, the Collateral Agent, the Manager, GEBAB, other persons
providing services with respect to the Vessels and other property of the Owners,
may be subject to the fiduciary responsibility provisions of Title I of ERISA.
The prohibited transaction provisions of Section 4975 of the Code and Section
406 of ERISA would apply with respect to transactions involving Holdings, the
Issuer or the Owners or the Vessels and a related party to a Plan unless such
transactions are subject to a statutory or administrative exemption.
Additionally, if Holdings, the Issuer, the Owners or the Collateral Agent were
deemed to hold Plan assets, each holder of a Security may be subject to the
fiduciary responsibility provisions


                                      -146-
<PAGE>

of Title I of ERISA with respect to its right to consent or withhold consent to
amendments to any of the Indentures or the Warrant Agreement and with respect to
its right to vote on actions to be taken or not taken if an Event of Default
occurs. As of the date hereof, the Company believes that each of the Owners will
qualify as an operating company within the meaning of the Regulations. However,
Plans considering the purchase of the Securities should consult with their own
independent legal counsel concerning the status of the Owners under the
Regulations and any ERISA considerations relevant thereto.

         In addition, certain affiliates of Holdings, the Issuer, the Owners,
the Manager, GEBAB, the Collateral Agent and the Trustees may be considered to
be parties in interest or fiduciaries with respect to many Plans. An investment
by such a Plan in Securities may be a prohibited transaction under ERISA and the
Code unless such investment is subject to a statutory or administrative
exemption.

         As a result, each prospective initial holder of the Securities, each
prospective transferee acquiring any of the Securities and each prospective
owner (or transferee thereof) of a beneficial interest in any of the Securities
(each a "Prospective Owner") is or will be deemed to have represented and
warranted to Holdings, the Owners, the Issuer, the Trustees, the Collateral
Agent, the Manager and GEBAB that either (1) the Prospective Owner is not a Plan
and the Prospective Owner is not directly or indirectly acquiring the relevant
Securities on behalf of, as investment manager of, as named fiduciary of, as
trustee of, or with assets of a Plan, (2) to the extent such purchase is made by
or on behalf of a bank collective investment fund maintained by the purchaser in
which no plan (together with any other plans maintained by the same employer or
employee organization) has an interest in excess of 10% of the total assets in
such collective investment fund, and the other applicable conditions of
Prohibited Transaction Class Exemption 91-38 issued by the Department of Labor
are satisfied, (3) to the extent such purchase is made by or on behalf of an
insurance company pooled separate account maintained by the purchaser in which,
at any time while the Securities are outstanding, no plan (together with any
other plans maintained by the same employer or employee organization) has an
interest in excess of 10% of the total of all assets in such pooled separate
account, and the other applicable conditions of Prohibited Transaction Class
Exemption 90-1 issued by the Department of Labor are satisfied, (4) to the
extent such purchase is made on behalf of a plan by (A) an investment adviser
registered under the Investment Advisers Act of 1940, as amended (the "1940
Act"), that had as of the last day of its most recent fiscal year total assets
under its management and control in excess of $50.0 million and had
stockholders' or partners' equity in excess of $750,000, as shown in its most
recent balance sheet prepared in accordance with GAAP, or (B) a bank as defined
in Section 202(a)(2) of the 1940 Act, with equity capital in excess of $1.0
million as of the last day of its most recent fiscal year, or (C) an insurance
company which is qualified under the laws of more than one state to manage,
acquire or dispose of any assets of a pension or welfare plan, which insurance
company has as of the last day of its most recent fiscal year, net worth in
excess of $1.0 million and which is subject to supervision and examination by a
state authority having supervision over insurance companies and, in any case,
such investment adviser, bank or insurance company is otherwise a qualified
professional asset manager, as such term is used in Prohibited Transaction Class
Exemption 84-14 issued by the Department of Labor, and the assets of such plan
when combined with the assets of other plans established or maintained by the
same employer (or affiliate thereof) or employee organization and managed by
such investment adviser, bank or insurance company, do not represent more than
20% of the total client assets


                                      -147-
<PAGE>

managed by such investment adviser, bank or insurance company at the time of the
transaction, and the other applicable conditions of such exemption are otherwise
satisfied, (5) to the extent such plan is a governmental plan (as defined in
Section 3 of ERISA) which is not subject to the provisions of Title I of ERISA
or Section 401 of the Code, (6) to the extent such purchase is made by or on
behalf of an insurance company using the assets of its general account, the
reserves and liabilities for the general account contracts held by or on behalf
of any plan, together with any other plans maintained to the same employer (or
its affiliate) or employee organization, do not exceed 10% of the total reserves
and liabilities of the insurance company general account (exclusive of separate
account liabilities), plus surplus as set forth in the National Association of
Insurance Commissioners Annual Statement filed with the state of domicile of the
insurer, in accordance with Prohibited Transaction Class Exemption 95-60, and
the other applicable conditions of such exemption are otherwise satisfied, (7)
to the extent such purchase is made by an in-house asset manager within the
meaning of Part IV(a) of Prohibited Transaction Class Exemption 96-23, such
manager has made or properly authorized the decision for such plan to purchase
Securities, under circumstances such that Prohibited Transaction Class Exemption
96-23 is applicable to the purchase and holding of such Securities or (8) the
proposed acquisition or transfer will qualify for a statutory or administrative
prohibited transaction exemption under ERISA and the Code or will not give rise
to a transaction described in Section 406 of ERISA or Section 4975(c)(l) of the
Code for which a statutory or administrative exemption is unavailable.

         Any Plan fiduciary that proposes to cause a Plan to purchase Securities
should consider whether such purchase would be appropriate under the general
fiduciary standards of prudence and diversification, taking into account the
overall investment policy of the Plan and its existing portfolio and should
consult with its counsel with respect to the potential applicability of ERISA
and the Code.

         PROSPECTIVE PLAN INVESTORS SHOULD CONSULT WITH THEIR LEGAL AND OTHER
ADVISORS CONCERNING THE IMPACT OF ERISA AND THE CODE (AND, PARTICULARLY IN THE
CASE OF NON-ERISA PLANS AND ARRANGEMENTS, ANY ADDITIONAL STATE LAW
CONSIDERATIONS), AND THE POTENTIAL CONSEQUENCES IN THEIR SPECIFIC CIRCUMSTANCES
OF AN INVESTMENT IN THE SECURITIES, PRIOR TO MAKING AN INVESTMENT IN THE
SECURITIES.

                      CERTAIN ISLE OF MAN TAX CONSEQUENCES

         The Issuer is prohibited from making, and accordingly shall not make,
any offer or invitation to any resident of the Isle of Man to subscribe for
Exchange Notes.

         Holdings is prohibited from making, and accordingly shall not make, any
offer or invitation to any resident of the Isle of Man to subscribe for
Warrants.

         By acquiring and holding any Exchange Notes or Warrants, the holder
will be deemed to warrant as a continuing warranty that the holder is not
resident for taxation purposes in the Isle of Man unless the holder is acting as
a trustee or nominee for a person not resident for taxation purposes, in the
Isle of Man or is a Manx exempt or international company, and accordingly the
entry of a Manx address on the Register of Members of the Issuer or Holdings, as
the case may be, will


                                      -148-
<PAGE>

not be permitted unless evidence is produced to the Registrar that the holder is
a trustee or nominee for a person not resident for taxation purposes in the Isle
of Man or is a Manx exempt or
international company.

         Special Isle of Man counsel has advised the Issuer that no withholding
taxes will be imposed on payments of principal, interest or premium (if any)
thereon with respect to the Exchange Notes and that the Holders will not be
subject to any income taxes imposed by the Isle of Man solely as a result of
owning the Exchange Notes. Investors should consult their own tax advisors
regarding whether the purchase of the Exchange Notes in conjunction with an
investor's other activities in the Isle of Man, may subject an investor to any
taxes imposed by the Isle of Man.

         To the extent the Isle of Man in the future does impose a withholding
tax with respect to payments of principal, interest or premium (if any) on the
Exchange Notes, the Issuer will make the required withholding and is required to
gross-up or indemnify Holders for amounts withheld. Pursuant to the Indentures,
in the event the Isle of Man does impose a withholding tax with respect to such
payments, the Issuer is obligated to take any lawful action to the extent
necessary to prevent or avoid the imposition of any withholding taxes, including
changing its jurisdiction of incorporation or residence; PROVIDED, HOWEVER, that
the Issuer will not be required to take, or fail to take, any action (x) if in
the opinion of counsel such act or failure to act would violate applicable law
or (y) if in the reasonable opinion of the Issuer the actions necessary to avoid
or prevent imposition of such taxes would be unduly burdensome. For purposes of
clause (y) of the immediately preceding sentence, a requirement to change the
jurisdiction of the Issuer's incorporation or residence will not be treated as
unduly burdensome unless changing the Issuer's jurisdiction of incorporation or
residence to such other jurisdiction or location would subject the Issuer to
charges in such other jurisdiction, including but not limited to taxes imposed
on or measured by its income, receipts, property, assets, capital, sales or
value-added.

         Furthermore, special Isle of Man counsel has advised Holdings that the
Holders of the Warrants will not be subject to any income or withholding taxes
imposed by the Isle of Man solely as a result of owning the Warrants, exercising
the Warrants to purchase Holdings Common Stock or owning Holdings Common Stock.
Investors should consult their own tax advisors regarding whether the same, in
conjunction with an investor's other activities in the Isle of Man, may subject
an investor to any taxes imposed by the Isle of Man.

                              PLAN OF DISTRIBUTION

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


                                      -149-
<PAGE>

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

         For a period of 180 days after the Expiration Date the 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 to pay all expenses
incidental to the Exchange Offer (including the expenses of one counsel for the
Holders of the Securities) other than commissions or concessions of any brokers
or dealers and will indemnify the Holders of the Securities (including any
broker-dealers) against certain liabilites, including liabilities under the
Securities Act.

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

         The distribution of the Securities in Canada is being made only on a
private placement basis exempt from the requirement that Navigator Gas Transport
and Holdings prepare and file a prospectus with the securities regulatory
authorities in each province where trades of Securities are effected.
Accordingly, any resale of the Securities in Canada must be made in accordance
with applicable securities laws which will vary depending on the relevant
jurisdiction, and which may require resales to be made in accordance with
available statutory exemptions or pursuant to a discretionary exemption granted
by the applicable Canadian securities regulatory authority. Purchasers are
advised to seek legal advice prior to any resale of the Securities.

REPRESENTATIONS OF PURCHASERS

         Each purchaser of Securities in Canada who receives a purchase
confirmation will be deemed to represent to Navigator Gas Transport, Holdings
and the dealer from whom such purchase confirmation is received that (i) such
purchaser is entitled under applicable provincial securities laws to purchase
such Securities without the benefit of a prospectus qualified under such
securities laws, (ii) where required by law, that such purchaser is purchasing
as principal and not as agent and (iii) such purchaser has reviewed the text
below under "TRANSFER RESTRICTIONS."


                                      -150-
<PAGE>

RIGHTS OF ACTION (ONTARIO PURCHASERS)

         The Securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Section 32 of the Regulation under the SECURITIES ACT (Ontario). As a result,
Ontario purchasers must rely on other remedies that may be available, including
common law rights of action for damages or rescission or rights of action under
the civil liability provisions of the U.S. federal securities laws.

ENFORCEMENT OF LEGAL RIGHTS

         All of the directors and officers of Navigator Gas Transport, Holdings
and the Owners as well as the experts named herein may be located outside of
Canada and, as a result, it may not be possible for Canadian purchasers to
effect service of process within Canada upon Navigator Gas Transport, Holdings,
the Owners or such persons. All or a substantial portion of the assets of

                                     RATING

         Moody's has rated the First Priority Existing Notes B1 and the Second
Priority Existing Notes B3, Standard & Poor's has rated the First Priority
Existing Notes B and the Second Priority Existing Notes B and Duff & Phelps has
rated the First Priority Existing Notes BB- and the Second Priority Existing
Notes B. A security rating is not a recommendation to buy, sell or hold
securities and may be subject to revision or withdrawal at any time. The ratings
of the Rating Agencies assigned to the Notes address the likelihood of the
receipt by Holders of the Existing Notes of all distributions to which such
Holders are entitled. The ratings assigned to the Notes do not represent any
assessment of the likelihood that principal prepayments might differ from those
originally anticipated or address the possibility that Holders might suffer a
lower than anticipated yield. In the event that the rating initially assigned to
any of the Notes is subsequently lowered for any reason, no person or entity is
obligated to provide any additional support or credit enhancement with respect
to such Note. The ratings do not address the possibility that Holders of the
Existing Notes may suffer a lower than anticipated yield.

         The Issuer has not requested a rating on the Notes by any rating
agencies other than the Rating Agencies. However, there can be no assurance as
to whether any other rating agency will rate the Notes, or, if it does, what
rating would be assigned by any such other rating agency. A rating on the Notes
by another rating agency, if assigned at all, may be lower than the ratings
assigned to the Note by the Rating Agencies.

a vessel, confiscation and damage resulting from hostilities, mines, strikes,
riots and civil commotions. However, a vessel subject to this form of insurance

                                     PART II

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

NAVIGATOR GAS TRANSPORT PLC ("NAVIGATOR GAS TRANSPORT"), NAVIGATOR GAS (IOM I-A)
LIMITED, NAVIGATOR GAS (IOM I-B) LIMITED, NAVIGATOR GAS (IOM I-C) LIMITED,
NAVIGATOR GAS (IOM I-D) LIMITED AND NAVIGATOR GAS (IOM I-E) LIMITED (EACH, AN
"OWNER" AND TOGETHER WITH NAVIGATOR GAS TRANSPORT, THE "COMPANIES")

         Each of the Companies is a corporation incorporated under the laws of
the Isle of Man. Section 151 of the Isle of Man Companies Act 1931 provides that
any provision (whether contained in the articles of association of the
corporation or elsewhere) exempting any director, officer or auditor
(collectively, "Officer") or indemnifying him or her against any liability which
would attach to him or her in relation to any negligence, default, breach of
duty or breach of trust is void. However, Section 151 also provides that an Isle
of Man corporation may indemnify any Officer against any liability incurred by
him or her in defending any proceedings, whether civil or criminal, in which
judgment is given in his or her favor or in which he or she is acquitted or in
connection with any application under Section 337 of the Isle of Man Companies
Act 1931 in which relief is granted by a court. Section 337 provides that, if in
any proceedings for negligence, default, breach of duty or breach of trust
against any Officer it appears to the court hearing the case that the person is
or may be liable in respect of the negligence, default, breach of duty or breach
of trust, but that he or she has acted honestly and reasonably and that, having
regard to all the circumstances of the case, including those connected with his
appointment, he or she ought fairly be excused, that court may relieve him or
her either wholly or partly his or her liability on such terms as the court
thinks fit. Additionally, under Section 337, where any Officer has reason to
believe that any claim will or might be made against him or her, he or she may
apply to court for relief as if an action had already been brought against him.

         An Isle of Man corporation has the power to purchase and maintain
insurance on behalf of an Officer against any liability alleged against him or
her for negligence, default, breach of duty or breach of trust.

         Article 126 of the Articles of Association of each of the Companies
provides for indemnification of directors and officers as follows:

         Every director or other officer of the Company shall be entitled to be
         indemnified out of the assets of the Company against all losses or
         liabilities (including any such liability as is mentioned in paragraph
         (c) of the proviso to Section 151 of the Companies Act [1931]), which
         he may sustain or incur in or about the execution of the duties of his
         office or otherwise in relation thereto, and no director or other
         officer shall be liable for any loss, damage or misfortune which may
         happen to or be incurred by the Company in the execution of the duties
         of his office or in relation thereto. But this Article shall only have
         effect insofar as its provisions are not avoided by the said section.

         The effectiveness of such article is subject to the provisions of
Section 151 of the Isle of Man Companies Act 1931 as discussed above.

ITEM 22. UNDERTAKINGS

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

5.       (1) Subject to the provisions of the Act and without prejudice to any

<PAGE>

                                                                               6


6. Subject to the provisions of the Act and the articles, redeemable preference
shares may be issued on such terms and in such manner as may be provided by the
articles.

7. The Company may exercise the powers of paying commissions conferred by the
Act. Subject to the provisions of the Act, any such commissions may be satisfied
by the payment of cash or by the allotment of fully or partly paid shares or
partly in one way and partly in the other.

8. Except as required by law, no person shall be recognised by the Company as
holding any share upon any trust and (except as otherwise provided by the
articles or by law) the Company shall not be bound by or recognise any interest
in any share except an absolute right to the entirety thereof in the holder.

9. The shares shall be at the disposal of the Directors, and (save as otherwise
directed by the Company in General Meeting) they may allot or otherwise dispose
of them to such persons at such times and generally on such terms and conditions
as they think proper, subject nevertheless to article 2 and provided that no
shares shall be issued at a discount, except as provided by Section 47 of the
Act.

10. If at any time the share capital is divided into different classes of
shares, the rights attached to any class (unless otherwise provided by the terms
of issue of the shares of that class) may be varied with the consent in writing
of the holders of all of the issued shares of that class, or with the sanction
of an extraordinary resolution passed at a separate general meeting of the
holders of the shares of the class. To every such separate general meeting the
provisions of these regulations relating to general meetings shall in the case
of the number of holders of a particular class of shares being two or more
mutatis mutandis apply, but so that the necessary quorum shall be two persons at
least holding or representing by proxy one-third of the issued


<PAGE>

                                                                               7


shares of the class, and that any holder of shares of the class present in
person or by proxy may demand a poll. In the case of the number of holders of a
particular class of shares being one, one person holding or representing all the
issued shares of the class shall be a quorum.

11. The Company may issue share warrants to bearer in respect of any fully
paid-up shares of the Company, stating that the bearer of the warrant is
entitled to the shares therein specified. Such warrants shall be issued upon
such terms and subject to such conditions as may be resolved upon by the
Directors. Subject to the provisions of the Act and of these articles the holder
of a share warrant shall be deemed to be a member of the Company and shall be
entitled to the same rights and privileges as he would have had if his name had
been included in the share register of the Company as the holder of the shares.


                               SHARE CERTIFICATES

12.      (1) Every member, upon becoming the holder of any shares shall be
         entitled

                  (a) without payment, to one certificate for all the shares of
                  each class held by him (and, upon transferring a part of his
                  holding of shares of any class, to a certificate for the
                  balance of such holding); or

                  (b) to several certificates each for one or more of his shares
                  upon payment, for every certificate after the first, of such
                  reasonable sum as the Directors may determine.

         (2) Every certificate shall be sealed with the seal and shall specify
         the number, class and distinguishing numbers (if any) of the shares to
         which it relates and the amount or respective amounts paid up thereon.


<PAGE>

                                                                               8


         (3) The Company shall not be bound to issue more than one certificate
         for shares held jointly by several persons and delivery of a
         certificate to one joint holder shall be a sufficient delivery to all
         of them.

13. If a share certificate is defaced, worn-out, lost or destroyed, it may be
renewed on such terms (if any) as to evidence and indemnity and payment of the
expenses reasonably incurred by the Company in investigating evidence as the
Directors may determine but otherwise free of charge, and (in the case of
defacement or wearing-out) on delivery up of the old certificate.

14. The Company shall have a first and paramount lien on every share for all
moneys (whether presently payable or not) payable at a fixed time or called in
respect of that share. The Directors may at any time declare any share to be
wholly or in part exempt from the provisions of this regulation. The Company's
lien on a share shall extend to any amount payable in respect of it.

15. The Company may sell in such manner as the Directors determine any shares on
which the Company has a lien if a sum in respect of which the lien exists is
presently payable and is not paid within fourteen clear days after notice has
been given to the holder of the share or to the person entitled to it in
consequence of the death or bankruptcy of the holder, demanding payment and
stating that if the notice is not complied with the shares may be sold.

16. To give effect to a sale the Directors may authorise some person to execute
an instrument of transfer of the shares, sold to, or in accordance with the
directions of, the purchaser. The title of the transferee to the shares shall
not be affected by any irregularity in or invalidity of the proceedings in
reference to the sale.


<PAGE>

                                                                               9


17. The net proceeds of the sale, after payment of the costs, shall be applied
in payment of so much of the sum for which the lien exists as is presently
payable, and any residue shall (upon surrender to the Company for cancellation
of the certificate for the shares sold and subject to a like lien for any moneys
not presently payable as existed upon the shares before the sale) be paid to the
person entitled to the shares at the date of the sale.


                         CALLS ON SHARES AND FORFEITURE

18. Subject to the terms of allotment, the Directors may make calls upon the
members in respect of any moneys unpaid on their shares (whether in respect of
nominal value or premium) and each member shall (subject to receiving at least
fourteen clear days notice specifying when and where payment is to be made) pay
to the Company as required by the notice the amount called on his shares. A call
may be required to be paid by instalments. A call may, before receipt by the
Company of any sum due thereunder, be revoked in whole or in part and payment of
a call may be postponed in whole or in part. A person upon whom a call is made
shall remain liable for calls made upon him notwithstanding the subsequent
transfer of the shares in respect whereof the call was made.

19. A call shall be deemed to have been made at the time when the resolution of
the Directors authorising the call was passed.

20. The joint holders of a share shall be jointly and severally liable to pay
all calls in respect thereof.

21. If a call remains unpaid after it has become due and payable the person from
whom it is due and payable shall pay interest on the amount unpaid from the day
it became due and payable until it is paid at the rate fixed by the terms of
allotment of the


<PAGE>

                                                                              10


share or in the notice of the call or, if no rate is fixed, at the rate of
(pound)5 per centum per annum but the Directors may waive payment of the
interest wholly or in part.

22. An amount payable in respect of a share on allotment or at any fixed date,
whether in respect of nominal value or premium or as an instalment of a call,
shall be deemed to be a call and if it is not paid the provisions of the
articles shall apply as if that amount had become due and payable by virtue of a
call.

23. Subject to the terms of allotment, the Directors may make arrangements on
the issue of shares for a difference between the holders in the amounts and
times of payment of calls on their shares.

24. If a call remains unpaid after it has become due and payable the Directors
may give to the person from whom it is due not less than fourteen clear days'
notice requiring payment of the amount unpaid together with any interest which
may have accrued. The notice shall name the place where payment is to be made
and shall state that if the notice is not complied with the shares in respect of
which the call was made will be liable to be forfeited.

25. If the notice is not complied with any share in respect of which it was
given may, before the payment required by the notice has been made, be forfeited
by a resolution of the Directors and the forfeiture shall include all dividends
or other moneys payable in respect of the forfeited shares and not paid before
the forfeiture.

26. Subject to the provisions of the Act, a forfeited share may be sold,
re-allotted or otherwise disposed of on such terms and in such manner as the
Directors determine either to the person who was before the forfeiture the
holder or to any other person and at any time before sale, re-allotment or other
disposition, the forfeiture may be cancelled on such terms as the Directors
think fit. Where for the purposes of its


<PAGE>

                                                                              11


disposal a forfeited share is to be transferred to any person the Directors may
authorise some person to execute an instrument of transfer of the share to that
person.

27. A person any of whose shares have been forfeited shall cease to be a member
in respect of them and shall surrender to the Company for cancellation the
certificate for the shares forfeited but shall remain liable to the Company for
all moneys which at the date of forfeiture were presently payable by him to the
Company in respect of those shares with interest at the rate at which interest
was payable on those moneys before the forfeiture or, if no interest was so
payable, at the rate of (pound)5 per centum per annum from the date of
forfeiture until payment but the Directors may waive payment wholly or in part
or enforce payment without any allowance for the value of the shares at the time
of forfeiture or for any consideration received on their disposal.

28. A statutory declaration by a Director or the secretary that a share has been
forfeited on a specified date shall be conclusive evidence of the facts stated
in it as against all persons claiming to be entitled to the share and the
declaration shall (subject to the execution of an instrument of transfer if
necessary) constitute a good title to the share and the person to whom the share
is disposed of shall not be bound to see to the application of the
consideration, if any, nor shall his title to the share be affected by any
irregularity in or invalidity of the proceedings in reference to the forfeiture
or disposal of the share.


                               TRANSFER OF SHARES

29. The instrument of transfer of a share may be in any usual form or in any
other form which the Directors may approve and shall be executed by or on behalf
of the transferor and, unless the share is fully paid, by or on behalf of the
transferee.


<PAGE>

                                                                              12


30. No transfer of any share in the capital of the Company to any person not
already a member of the Company shall be made or registered without the previous
sanction of the Directors, who may without assigning any reason, decline to give
any such sanction. The Directors may also suspend the registration of transfers
during the fourteen days immediately preceding the Ordinary General Meeting in
each year. The Directors may decline to recognise any instrument of transfer
unless accompanied by the certificate of the shares to which it relates, and
such other evidence as the Directors may reasonably require to show the right of
the transferor to make the transfer. The Directors may decline to register a
transfer of any shares on which the Company has a lien. If the Directors refuse
to register a transfer of any share they shall within two months after the date
on which the transfer was lodged with the Company send to the transferee notice
of the refusal as required by section 67 of the Act.

31. The Company shall be entitled to retain any instrument of transfer which is
registered, but any instrument of transfer which the Directors refuse to
register shall be returned to the person lodging it when notice of the refusal
is given.


                             TRANSMISSION OF SHARES

32. If a member dies the survivor or survivors where he was a joint holder, and
his personal representatives where he was a sole holder or the only survivor of
joint holders, shall be the only persons recognised by the Company as having any
title to his interest; but nothing herein contained shall release the estate of
a deceased member from any liability in respect of any share which had been
jointly held by him.

33. A person becoming entitled to a share in consequence of the death or
bankruptcy of a member may, upon such evidence being produced as the Directors
may properly require, elect either to become the holder of the share or to have
some


<PAGE>

                                                                              13


person nominated by him registered as the transferee. If he elects to become the
holder he shall give notice to the Company to that effect. If he elects to have
another person registered he shall execute an instrument of transfer of the
share to that person. All articles relating to the transfer of shares shall
apply to the notice or instrument of transfer as if it were an instrument of
transfer executed by the member and the death or bankruptcy of the member had
not occurred.

34. A person becoming entitled to a share in consequence of the death or
bankruptcy of a member shall have the rights to which he would be entitled if he
were the holder of the share, except that he shall not, before being registered
as the holder of the share, be entitled in respect of it to attend or vote at
any meeting of the Company or at any separate meeting of the holders of any
class of shares in the Company.


                           ALTERATION OF SHARE CAPITAL

35.      The Company may by ordinary resolution -

                  (a) increase its share capital by new shares of such amount as
                  the resolution prescribes;

                  (b) consolidate and divide all or any or its share capital
                  into shares of larger amount than its existing shares;

                  (c) subject to the provisions of the Act, sub-divide its
                  shares, or any of them, into shares of smaller amount and the
                  resolution may determine that, as between the shares resulting
                  from the sub-division, any of them may have any preference or
                  advantage as compared with the others; and


<PAGE>

                                                                              14


                  (d) cancel shares which, at the date of the passing of the
                  resolution, have not been taken or agreed to be taken by any
                  person and diminish the amount of its share capital by the
                  amount of the shares so cancelled.

36. Whenever as a result of a consolidation of shares any members would become
entitled to fractions of a share, the Directors may, instead of issuing the
fractions of a share, on behalf of those members, sell the shares representing
the fractions for the best price reasonably obtainable to any person (including,
subject to the provisions of the Act, the Company) and distribute the net
proceeds of sale in due proportion among those members, and the Directors may
authorise some person to execute an instrument of transfer of the shares to, or
in accordance with the directions of, the purchaser. The transferee shall not be
bound to see to the application of the purchase money nor shall his title to the
shares be affected by any irregularity in or invalidity of the proceedings in
reference to the sale.

37. Subject to the provisions of the Act, the Company may by special resolution
reduce its share capital, any capital redemption reserve and any share premium
account in any way.


                         CONVERSION OF SHARES INTO STOCK

38. The Company may by ordinary resolution convert any paid-up shares into stock
and reconvert any stock into paid-up shares of any denomination.

39. The holders of stock may transfer the same, or any part thereof, in the same
manner, and subject to the same regulations, as, and subject to which, the
shares from which the stock arose might previously to conversion have been
transferred, or as near thereto as circumstances admit; but the Directors may
from time to time fix the minimum amount of stock transferable and restrict or
forbid the transfer of fractions of that


<PAGE>

                                                                              15


minimum, but the minimum shall not exceed the nominal amount of the shares from
which the stock arose.

40. The holders of stock shall, according to the amount of the stock held by
them, have the same rights, privileges and advantages as regards dividends,
voting at meetings of the Company and other matters as if they held the shares
from which the stock arose, but no such privilege or advantage (except
participation in the dividends and profits of the Company) shall be conferred by
any such aliquot part of stock as would not, if existing in shares, have
conferred that privilege or advantage.

41. Such of the regulations of the Company as are applicable to paid-up shares
shall apply to stock and the words "shares" and "shareholder" therein shall
include "stock" and "stockholder".


                         REDEMPTION OF PREFERENCE SHARES

42. Subject to the provisions of the Act, the redemption of redeemable
preference shares shall be effected on such terms and in such manner, as may be
provided by the articles.


                                GENERAL MEETINGS

43. All general meetings other than annual general meetings shall be called
extraordinary general meetings.

44. The Directors may call general meetings, and on the requisition of a member
pursuant to the provisions of the Act, shall forthwith proceed to convene an
extraordinary general meeting for a date not later than eight weeks after
receipt of the


<PAGE>

                                                                              16


requisition. If there are not within the Isle of Man sufficient Directors to
call a general meeting, any Director or any member of the Company may call a
general meeting.


                           NOTICE OF GENERAL MEETINGS

45. An annual general meeting and an extraordinary general meeting called for
the passing of a special resolution or a resolution appointing a person as a

                  majority together holding not less than ninety five per cent
                  in nominal value of the shares giving that right.

                                                                              17


46. The accidental omission to give notice of a meeting to or the non-receipt of

meeting shall stand adjourned to the same day in the next week at the same time
and place or to such time and place as the Directors may determine.

49. The Chairman, if any, of the Board of Directors or in his absence some other

                                                                              18


51. A Director shall, notwithstanding that he is not a member, be entitled to

(and shall if so directed by the meeting), adjourn the meeting from time to time
and from place to place, but no business shall be transacted at an adjourned

meeting had the adjournment not taken place. When a meeting is adjourned for
fourteen days or more, at least seven clear days' notice shall be given
specifying the time and place of the adjourned meeting and the general nature of
the business to be transacted. Otherwise it shall not be necessary to give any
such notice.

53. A resolution put to the vote of a meeting shall be decided on a show of

                  (c) by a member or members representing no less than one-tenth
                  of the total voting rights of all the members having the right
                  to vote at the meeting; or

                  (d) by a member or members holding shares conferring a right
                  to vote at the meeting being shares on which an aggregate sum
                  has been paid up equal to not less than one-tenth of the total
                  sum paid up on all the shares conferring that right;

                                                                              19


and a demand by a person as proxy for a member shall be the same as a demand by
the member.

54. Unless a poll is duly demanded a declaration by the Chairman that a
resolution has been carried or carried unanimously, or by a particular majority,
or lost, or not carried by a particular majority and an entry to that effect in
the minutes of the meeting shall be conclusive evidence of the fact without
proof of the number or proportion of the votes recorded in favour of or against
the resolution.

55. The demand for a poll may, before the poll is taken, be withdrawn but only
with the consent of the Chairman and a demand so withdrawn shall not be taken to
have invalidated the result of a show of hands declared before the demand was
made.

56. A poll shall be taken as the Chairman directs and he may appoint scrutineers
(who need not be members) and fix a time and place for declaring the result of
the poll. The result of the poll shall be deemed to be the resolution of the
meeting at which the poll was demanded.

57. In the case of an equality of votes, whether on a show of hands or on a
poll, the Chairman shall be entitled to a casting vote in addition to any other
vote he may have.

58. A poll demanded on the election of a Chairman or on a question of
adjournment shall be taken forthwith. A poll demanded on any other question
shall be taken either forthwith or at such time and place as the Chairman
directs not being more than thirty days after the poll is demanded. The demand
for a poll shall not prevent the continuance of a meeting for the transaction of
any business other than the question on which the poll was demanded. If a poll
is demanded before the declaration of the result of a show of hands and the
demand is duly withdrawn, the meeting shall continue as if the demand had not
been made.

59. No notice need be given of a poll not taken forthwith if the time and place
at which it is to be taken are announced at the meeting at which it is demanded.
In any other case at least seven clear days notice shall be given specifying the
time and place at which the poll is to be taken.

60. A resolution in writing executed by or on behalf of each member who would
have been entitled to vote upon it if it had been proposed at a general meeting
at which he was present shall be as effectual as if it had been passed at a
general meeting duly convened and held and may consist of several instruments in
the like form each executed by or on behalf of one or more members, provided the
provisions of Section 118B of the Act are complied with and that such resolution
is received by the Company at its registered office within seven days of the
date of its execution in terms hereof.





                                VOTES OF MEMBERS

61. Subject to any rights or restrictions attached to any shares, on a show of
hands every member who (being an individual) is present in person or by proxy or
(being a corporation) is present by a duly authorised representative, not being
himself a member, shall have one vote and on a poll every member entitled to
vote shall have one vote for every share of which he is the holder.

62. In the case of joint holders the vote of the senior who tenders a vote,
whether in person or by proxy, shall be accepted to the exclusion of the votes
of the other joint holders; and seniority shall be determined by the order in
which the names of the holders stand in the register of members.

63. A member in respect of whom an order has been made by any court having
jurisdiction (whether in the Isle of Man or elsewhere) in matters concerning
mental disorder may vote, whether on a show of hands or on a poll, by his
receiver, curator bonis or other person authorised in that behalf appointed by
that court, and any such receiver, curator bonis or other person may, on a poll,
vote by proxy. Evidence to the satisfaction of the Directors of the authority of
the person claiming to exercise the right to vote shall be deposited at the
office, or at such other place as is specified in accordance with the articles
for the deposit of instruments of proxy, not less than 48 hours before the time
appointed for holding the meeting or adjourned meeting at which the right to
vote is to be exercised and in default the right to vote shall not be
exercisable.

64. No member shall vote at any general meeting or at any separate meeting of
the holders of any class of shares in the Company, either in person or by proxy,
in respect of any share held by him unless all moneys presently payable by him
in respect of that share have been paid.

65. No objections shall be raised to the qualification of any voter except at
the meeting or adjourned meeting at which the vote objected to is tendered, and
every vote not disallowed at the meeting shall be valid. Any objection made in
due time shall be referred to the Chairman whose decision shall be final and
conclusive.

66. On a poll votes may be given either personally or by proxy. A member may
appoint more than one proxy to attend on the same occasion.

behalf of the appointor and shall be in the following form (or in a form as near

Directors may approve) -

permitted shall be invalid.

70. A vote given or poll demanded by proxy or by the duly authorised
representative of a corporation shall be valid notwithstanding the previous

notice of the determination was received by the Company at the office or at such
other place at which the instrument of proxy was duly deposited before the

any directions given by special resolution the business of the Company shall be
managed by the Directors who may exercise all the powers of the Company. No
alteration of the memorandum or articles and no such direction shall invalidate
any prior act of the Directors which would have been valid if that alteration
had not been made or that direction had not been given. The powers given by this
regulation shall not be limited by any special power given to the Directors by
the articles and a meeting of Directors at which a quorum is present may
exercise all powers exercisable by the Directors.

79. Without prejudice to the generality of the foregoing article the Directors
may from time to time at their discretion, raise or borrow, without the consent
of the members in General Meeting, such sum or sums of money for the purposes of
the Company's business as they may think fit and may secure the repayment of or
raise any such sum or sums as aforesaid in such manner and upon such terms and
conditions and in all other respects as they may think fit, and in particular by
mortgages, deeds of bond and security, or other charges upon the whole or any
part of the property and assets of the Company, present or future, including its
uncalled or unissued capital, or by the issue at such price as they may think
fit, of bonds or debentures or debenture stock of the Company, either charged
upon the whole or any part of the property and assets of the Company, or not so
charged, or in any other way that the Directors may think expedient, and the
Directors may issue debentures or debenture stock or paid-up shares to any
person or persons as consideration for the purchase of any goodwill, business or
property purchased by the Company.

80. The Directors may, by power of attorney or otherwise, appoint any person to
be the agent of the Company for such purposes and on such conditions as they
determine, including authority for the agent to delegate all or any of his
powers. The Company may exercise the powers conferred by Sections 32 and 104 of
the Companies Act, 1931 and those powers shall accordingly be exercisable by the
Directors.

81. The Directors may delegate any of their powers to any committee consisting
of one or more Directors. They may also delegate to any Managing Director or any
Director holding any other executive office such of their powers as they
consider desirable to be exercised by him. Any such delegation may be made
subject to any conditions the Directors may impose and either collaterally with
or to the exclusion of their own powers and may be revoked or altered. Subject
to any such conditions, the proceedings of a committee with two or more members
shall be governed by the articles regulating the proceedings of Directors so far
as they are capable of applying.


                               DIRECTORS GENERALLY

82. The Company may from time to time in general meeting increase or reduce the
number of Directors. The Company may by special resolution remove any Director
or by ordinary resolution appoint any person to be a Director.

intention to propose him, together with a notice in writing by the person to be
proposed of his willingness to be appointed.

84. The Directors shall have power at any time, and from time to time, to fill
any casual vacancy occurring in the Board of Directors or to appoint a person as
an additional Director.

about the performance of their duties as Directors.

                  absent without permission of the Directors from meetings of

                  that his office be vacated.

88. The shareholding qualification for Directors may be fixed by the Company in
general meeting, and unless and until so fixed no qualification shall be
required.

services outside the scope of the ordinary duties of a Director. Any such
appointment, agreement or arrangement may be made upon such terms as the
Directors determine and they may remunerate any such Director for his services

                  transaction or arrangement with the Company or in which the
                  Company is otherwise interested;

                  (b) may be a Director or other officer of, or employed by, or
                  a party to any transaction or arrangement with, or otherwise
                  interested in, any body corporate promoted by the Company or
                  in which the Company is otherwise interested; and

                  (c) shall not, by reason of his office, be accountable to the
                  Company for any benefit which he derives from any such office
                  or employment or from any such transaction or arrangement or
                  from any interest in any such body corporate and no such
                  transaction or arrangement shall be liable to be avoided on
                  the ground of any such interest or benefit.

91. For the purposes of the foregoing article -

                  (a) a general notice given to the Directors that a Director is

                  specified in the notice in any transaction or arrangement in
                  which a specified person or class of persons is interested
                  shall be deemed to be a disclosure that the Director has an
                  interest in any such transaction of the nature and extent so
                  specified; and

                  (b) an interest of which a Director has no knowledge and of
                  which it is unreasonable to expect him to have knowledge shall
                  not be treated as an interest of his.

otherwise than in the ordinary course of the Company's business and the sole
member is also a director of the Company, the Company should, unless the
contract is in writing, ensure that the terms of the contract are either set out
in a written memorandum or are recorded in the minutes of the first meeting of
the directors of the Company following the making of the contract.


                       DIRECTORS' GRATUITIES AND PENSIONS

93. Subject to the provisions of the Act, the Directors may provide benefits,

employment with the Company or with any body corporate which is or has been a
subsidiary of the Company or a predecessor of the Company or of any such
subsidiary and for any member of his family (including a spouse and a former
spouse) or any person who is or was dependent on him, and may (as well before as

proceedings as they think fit. A Director may, and the secretary at the request
of a Director shall, call a meeting of the Directors. Questions arising at a
meeting shall be decided by a majority of votes. In the case of an equality of
votes, the Chairman shall have a second or casting vote. A Director who is also
an alternate Director shall be

entitled in the absence of his appointor to a separate vote on behalf of his
appointor in addition to his own vote.

95. The quorum for the transaction of the business of the Directors may be fixed

who holds office only as an alternate Director shall, if his appointor is not
present, be counted in the quorum.

96. The continuing Directors or a sole continuing Director may act
notwithstanding any vacancies in their number, but, if the number of Directors
is less than the number fixed as the quorum, the continuing Directors or
Director may act only for the purpose of filling vacancies or of calling a
general meeting.

97. The Directors may appoint one of their number to be the Chairman of the
Board of Directors and may at any time remove him from that office. Unless he is
unwilling to do so, the Director so appointed shall preside at every meeting of
Directors at which he is present. But if there is no Director holding that
office, or if the Director holding it is unwilling to preside or is not present
within five minutes after the time appointed for the meeting, the Directors
present may appoint one of their number to be Chairman of the meeting.

98. All acts done by a meeting of Directors, or of a committee of Directors, or
by a person acting as a Director shall, notwithstanding that it be afterwards
discovered that there was a defect in the appointment of any Director or that
any of them were disqualified from holding office, or had vacated office, or
were not entitled to vote, be valid as if every such person had been duly
appointed and was qualified and had continued to be a Director and had been
entitled to vote.

99. A resolution in writing signed by all the Directors entitled to receive
notice of a meeting of Directors or of a committee of Directors shall be as
valid and effectual as

                                                                              33


if it had been passed at a meeting of Directors or (as the case may be) a
committee of Directors duly convened and held and may consist of several
documents in the like form each signed by one or more Directors, but a
resolution signed by an alternate need not also be signed by his appointor and,
if it is signed by a Director who has appointed an alternate Director, it need
not be signed by the alternate Director in that capacity.

100. Save as otherwise provided by the articles, a Director shall not vote at a
meeting of Directors or of a committee of Directors on any resolution concerning
a matter in which he has, directly or indirectly, an interest or duty which is
material and which conflicts or may conflict with the interest of the Company
unless he has declared the nature of his interest in the manner required by
Section 148 of the Act.

101.A Director shall not be counted in the quorum present at a meeting in
relation to a resolution on which he is not entitled to vote.

102.The Company may by ordinary resolution suspend or relax to any extent,
either generally or in respect of any particular matter, any provision of the
articles prohibiting a Director from voting at a meeting of Directors or of a
committee of Directors.

103. If a question arises at a meeting of Directors or of a committee of
Directors as to the right of a Director to vote, the question may, before the
conclusion of the meeting, be referred to the Chairman of the meeting and his
ruling in relation to any Director other than himself shall be final and
conclusive.

104. Any Director or member of a committee of the Directors may participate in a
meeting of the Directors or such committee by means of telephonic or similar
communications whereby all persons participating in the meeting can hear each
other and participation in a meeting in this manner shall be deemed to
constitute presence in person at such meeting. The location of such a telephonic
meeting shall be deemed

                                                                              34


to be the place at which the Chairman of the meeting was located at the time of
the meeting.




                             MANAGEMENT AND CONTROL

105. The management and control of the business of the Company shall be in and
from the Isle of Man or in and from such other place as the Directors shall
decide.






                                    SECRETARY

106. Subject to the provisions of the Act, the secretary shall be appointed by
the Directors for such term, at such remuneration and upon such conditions as
they may think fit; and any secretary so appointed may be removed by them.



                                     MINUTES

107. The Directors shall cause Minutes to be made in books kept for the purpose
- -

                  (a) of all appointments of officers made by the Directors; and

                                                                              35


                  (b) of all proceedings at meetings of the Company, of the
                  holders of any class of shares in the Company and of the
                  Directors, and of committees of Directors, including the names
                  of the Directors present at such meeting.


                                    THE SEAL

108. The Company shall have a Company Seal.

109. The seal shall only be used by the authority of the Directors or of a
committee of Directors authorised by the Directors. The Directors may determine
who shall sign any instrument to which the seal is affixed and unless otherwise
so determined it shall be signed by a Director and by the secretary or by a
second Director.


                                    DIVIDENDS

110. Subject to the provisions of the Act, the Company may by ordinary
resolution declare dividends in accordance with the respective rights of the
members, but no dividend shall exceed the amount recommended by the Directors.

111. Subject to the provisions of the Act, the Directors may pay interim
dividends if it appears to them that they are justified by the profits of the
Company available for distribution. If the share capital is divided into
different classes, the Directors may pay interim dividends on shares which
confer deferred or non-preferred rights with regard to dividend as well as on
shares which confer preferential rights with regard to dividend, but no interim
dividend shall be paid on shares carrying deferred or non-preferential rights
if, at the time of payment, any preferential dividend is in arrear. The
Directors may also pay at intervals settled by them any dividend payable at a
fixed rate


<PAGE>

                                                                              36


if it appears to them that the profits available for distribution justify the
payment. Provided the Directors act in good faith they shall not incur any
liability to the holders of shares conferring preferred rights for any loss they
may suffer by the lawful payment of an interim dividend on any shares having
deferred or non-preferred rights.

112. Except as otherwise provided by the rights attached to shares, all
dividends shall be declared and paid according to the amounts paid up on the
shares on which the dividend is paid. All dividends shall be apportioned and
paid proportionately to the amounts paid up on the shares during any portion or
portions of the period in respect of which the dividend is paid; but, if any
share is issued on terms providing that it shall rank for dividend as from a
particular date, that share shall rank for dividend accordingly.

113. A general meeting declaring a dividend may, upon the recommendation of the
Directors, direct that it shall be satisfied wholly or partly by the
distribution of assets and where any difficulty arises in regard to the
distribution, the Directors may settle the same and in particular may issue
fractional certificates and fix the value for distribution of any assets and may
determine that cash shall be paid to any member upon the footing of the value so
fixed in order to adjust the rights of members and may vest any assets in
trustees.

114. Any dividend or other moneys payable in respect of a share may be paid by
cheque sent by post to the registered address of the person entitled or, if two
or more persons are the holders of the share or are jointly entitled to it by
reason of the death or bankruptcy of the holder, to the registered address of
that one of those persons who is first named in the register of members or to
such person and to such address as the person or persons entitled may in writing
direct. Every cheque shall be made payable to the order of the person or persons
entitled or to such other person as the person or persons entitled may in
writing direct and payment of the cheque shall be a good discharge to the
Company. Any joint holder or other person jointly entitled to a share


<PAGE>

                                                                              37


as aforesaid may give receipts for any dividend or other moneys payable in
respect of the share.

115. No dividend or other moneys payable in respect of a share shall bear
interest against the Company unless otherwise provided by the rights attached to
the share.

116. Any dividend which has remained unclaimed for twelve years from the date
when it became due for payment shall, if the Directors so resolve, be forfeited
and cease to remain owing by the Company.


                                    ACCOUNTS

117.              (a) No member shall (as such) have any right of inspecting any
                  accounting records or other book or document of the Company
                  except as conferred by statute or authorised by the Directors
                  or by ordinary resolution of the Company.

                  (b) The Company shall prepare such accounts as may be required
                  by the Act and the laws of the Isle of Man.

                  (c) Subject to the Act and the laws of the Isle of Man the
                  Company may elect to dispense with compliance with the
                  requirements of the Act which relate to the audit of the
                  accounts of the Company.


                            CAPITALISATION OF PROFITS

Company -


<PAGE>

                                                                              38


                  (a) subject as hereinafter provided, resolve to capitalise any
                  undivided profits of the Company not required for paying any
                  preferential dividend (whether or not they are available for
                  distribution) or any sum standing to the credit of the
                  Company's share premium account or capital redemption reserve;

                  (b) appropriate the sum resolved to be capitalised to the
                  members who would have been entitled to it if it were
                  distributed by way of dividend and in the same proportions and
                  apply such sum on their behalf either in or towards paying up
                  the amounts, if any, for the time being unpaid on any shares
                  held by them respectively, or in paying up in full unissued
                  shares or debentures of the Company of a nominal amount, equal
                  to that sum, and allot the shares or debentures credited as
                  fully paid to those members, or as they may direct, in those
                  proportions, or partly in one way and partly in the other: but
                  the share premium account, the capital redemption reserve and
                  any profits which are not available for distribution may, for
                  the purposes of this regulation, only be applied in paying up
                  unissued shares to be allotted to members credited as fully
                  paid;

                  (c) make such provision by the issue of fractional
                  certificates or by payment in cash or otherwise as they
                  determine in the case of shares or debentures becoming
                  distributable under this regulation in fractions; and

                  (d) authorise any person to enter on behalf of all the members
                  concerned into an agreement with the Company providing for the
                  allotment to them respectively, credited as fully paid, of any
                  shares or debentures to which they are entitled upon such
                  capitalisation, any agreement made under such authority being
                  binding on all such members.

                                                                              39


                                     NOTICES

119. Any notice to be given to or by any person pursuant to the articles shall
be in writing except that a notice calling a meeting of the Directors need not
be in writing.

120. The Company may give any notice to a member either personally or by sending
it by post in a prepaid envelope addressed to the member at his registered
address or by leaving it at that address. In the case of joint holders of a
share, all notices shall be given to the joint holder whose name stands first in
the register of members in respect of the joint holding and notice so given
shall be sufficient notice to all the joint holders. A member whose registered
address is not within the British Islands and who gives to the Company an
address within the British Islands at which notices may be given to him shall be
entitled to have notices given to him at that address, but otherwise no such
member shall be entitled to receive any notice from the Company.

121. A member present, either in person or by proxy, at any meeting of the
Company or of the holders of any class of shares in the Company shall be deemed
to have received notice of the meeting and, where requisite, of the purposes for
which it was called.

122. Every person who becomes entitled to a share shall be bound by any notice
in respect of that share which, before his name is entered in the register of
members, has been duly given to a person from whom he derives his title.

123. Proof that an envelope containing a notice was properly addressed, prepaid
and posted shall be conclusive evidence that the notice was given. A notice
shall be deemed to be given at the expiration of 48 hours after the envelope
containing it was posted.


<PAGE>

                                                                              40


124. A notice may be given by the Company to the persons entitled to a share in
consequence of the death or bankruptcy of a member by sending or delivering it,
in any manner authorised by the articles for the giving of notice to a member,
addressed to them by name, or by the title of representatives of the deceased,
or trustee of the bankrupt or by any like description at the address, if any,
within the British Islands supplied for that purpose by the persons claiming to
be so entitled. Until such an address has been supplied, a notice may be given
in any manner in which it might have been given if the death or bankruptcy had
not occurred.


                                   WINDING UP

125. If the Company is wound up, the liquidator may, with the sanction of an
extraordinary resolution of the Company and any other sanction required by the
Act, divide among the members in specie the whole or any part of the assets of
the Company and may, for that purpose, value any assets and determine how the
division shall be carried out as between the members or different classes of
members. The liquidator may, with the like sanction, vest the whole or any part
of the assets in trustees upon such trusts for the benefit of the members as he
with the like sanction determines, but no member shall be compelled to accept
any assets upon which there is a liability.


                                    INDEMNITY

126. Every Director or other officer of the Company shall be entitled to be
indemnified out of the assets of the Company against all losses or liabilities
(including any such liability as is mentioned in paragraph (c) of the proviso to
Section 151 of the Act) which he may sustain or incur in or about the execution
of the duties of his office or otherwise in relation thereto, and no Director or
other officer shall be liable for any loss, damage or misfortune which may
happen to or be incurred by the Company in the execution of the duties of his
office or in relation thereto. But this Article shall only have effect in so far
as its provisions are not avoided by the said Section.

127. The Company may purchase and maintain indemnity insurance for the benefit
of each Director or other officer of the Company.

in any share except an absolute right to the entirety thereof in the holder.

9. The shares shall be at the disposal of the Directors, and (save as otherwise
directed by the Company in General Meeting) they may allot or otherwise dispose
of them to such persons at such times and generally on such terms and conditions
as they think proper, subject nevertheless to article 2 and provided that no
shares shall be issued at a discount, except as provided by Section 47 of the
Act.

10. If at any time the share capital is divided into different classes of
shares, the rights attached to any class (unless otherwise provided by the terms
of issue of the shares of that class) may be varied with the consent in writing
of the holders of all of the issued shares of that class, or with the sanction
of an extraordinary resolution passed at a separate general meeting of the
holders of the shares of the class. To every such separate general meeting the
provisions of these regulations relating to general meetings shall in the case
of the number of holders of a particular class of shares being two or more
mutatis mutandis apply, but so that the necessary quorum shall be two persons at
least holding or representing by proxy one-third of the issued shares of the
class, and that any holder of shares of the class present in person or by proxy
may demand a poll. In the case of the number of holders of a particular class of
shares being one, one person holding or representing all the issued shares of
the class shall be a quorum.

11. The Company may issue share warrants to bearer in respect of any fully
paid-up shares of the Company, stating that the bearer of the warrant is
entitled to the shares therein specified. Such warrants shall be issued upon
such terms and subject to such conditions as may be resolved upon by the
Directors. Subject to the provisions of the Act and of these articles the holder
of a share warrant shall be deemed to be a member of the Company and shall be
entitled to the same rights and privileges as he would have had if his name had
been included in the share register of the Company as the holder of the shares.


                               SHARE CERTIFICATES

12.      (1) Every member, upon becoming the holder of any shares shall be
         entitled

                  (a) without payment, to one certificate for all the shares of
                  each class held by him (and, upon transferring a part of his
                  holding of shares of any class, to a certificate for the
                  balance of such holding); or

                  (b) to several certificates each for one or more of his shares
                  upon payment, for every certificate after the first, of such
                  reasonable sum as the Directors may determine.

         (2) Every certificate shall be sealed with the seal and shall specify
         the number, class and distinguishing numbers (if any) of the shares to
         which it relates and the amount or respective amounts paid up thereon.

         (3) The Company shall not be bound to issue more than one certificate
         for shares held jointly by several persons and delivery of a
         certificate to one joint holder shall be a sufficient delivery to all
         of them.


<PAGE>

                                                                              10


13. If a share certificate is defaced, worn-out, lost or destroyed, it may be
renewed on such terms (if any) as to evidence and indemnity and payment of the
expenses reasonably incurred by the Company in investigating evidence as the
Directors may determine but otherwise free of charge, and (in the case of
defacement or wearing-out) on delivery up of the old certificate.

14. The Company shall have a first and paramount lien on every share for all
moneys (whether presently payable or not) payable at a fixed time or called in
respect of that share. The Directors may at any time declare any share to be
wholly or in part exempt from the provisions of this regulation. The Company's
lien on a share shall extend to any amount payable in respect of it.

15. The Company may sell in such manner as the Directors determine any shares on
which the Company has a lien if a sum in respect of which the lien exists is
presently payable and is not paid within fourteen clear days after notice has
been given to the holder of the share or to the person entitled to it in
consequence of the death or bankruptcy of the holder, demanding payment and
stating that if the notice is not complied with the shares may be sold.

16. To give effect to a sale the Directors may authorise some person to execute
an instrument of transfer of the shares, sold to, or in accordance with the
directions of, the purchaser. The title of the transferee to the shares shall
not be affected by any irregularity in or invalidity of the proceedings in
reference to the sale.

17. The net proceeds of the sale, after payment of the costs, shall be applied
in payment of so much of the sum for which the lien exists as is presently
payable, and any residue shall (upon surrender to the Company for cancellation
of the certificate for the shares sold and subject to a like lien for any moneys
not presently payable as existed upon the shares before the sale) be paid to the
person entitled to the shares at the date of the sale.

                                                                              11


                         CALLS ON SHARES AND FORFEITURE

18. Subject to the terms of allotment, the Directors may make calls upon the
members in respect of any moneys unpaid on their shares (whether in respect of
nominal value or premium) and each member shall (subject to receiving at least
fourteen clear days notice specifying when and where payment is to be made) pay
to the Company as required by the notice the amount called on his shares. A call
may be required to be paid by instalments. A call may, before receipt by the
Company of any sum due thereunder, be revoked in whole or in part and payment of
a call may be postponed in whole or in part. A person upon whom a call is made
shall remain liable for calls made upon him notwithstanding the subsequent
transfer of the shares in respect whereof the call was made.

19. A call shall be deemed to have been made at the time when the resolution of
the Directors authorising the call was passed.

20. The joint holders of a share shall be jointly and severally liable to pay
all calls in respect thereof.

21. If a call remains unpaid after it has become due and payable the person from
whom it is due and payable shall pay interest on the amount unpaid from the day
it became due and payable until it is paid at the rate fixed by the terms of
allotment of the share or in the notice of the call or, if no rate is fixed, at
the rate of (pound)5 per centum per annum but the Directors may waive payment of
the interest wholly or in part.

22. An amount payable in respect of a share on allotment or at any fixed date,
whether in respect of nominal value or premium or as an instalment of a call,
shall be deemed to be a call and if it is not paid the provisions of the
articles shall apply as if that amount had become due and payable by virtue of a
call.


<PAGE>

                                                                              12


23. Subject to the terms of allotment, the Directors may make arrangements on
the issue of shares for a difference between the holders in the amounts and
times of payment of calls on their shares.

24. If a call remains unpaid after it has become due and payable the Directors
may give to the person from whom it is due not less than fourteen clear days'
notice requiring payment of the amount unpaid together with any interest which
may have accrued. The notice shall name the place where payment is to be made
and shall state that if the notice is not complied with the shares in respect of
which the call was made will be liable to be forfeited.

25. If the notice is not complied with any share in respect of which it was
given may, before the payment required by the notice has been made, be forfeited
by a resolution of the Directors and the forfeiture shall include all dividends
or other moneys payable in respect of the forfeited shares and not paid before
the forfeiture.

26. Subject to the provisions of the Act, a forfeited share may be sold,
re-allotted or otherwise disposed of on such terms and in such manner as the
Directors determine either to the person who was before the forfeiture the
holder or to any other person and at any time before sale, re-allotment or other
disposition, the forfeiture may be cancelled on such terms as the Directors
think fit. Where for the purposes of its disposal a forfeited share is to be
transferred to any person the Directors may authorise some person to execute an
instrument of transfer of the share to that person.

27. A person any of whose shares have been forfeited shall cease to be a member
in respect of them and shall surrender to the Company for cancellation the
certificate for the shares forfeited but shall remain liable to the Company for
all moneys which at the date of forfeiture were presently payable by him to the
Company in respect of those shares with interest at the rate at which interest
was payable on those moneys before the forfeiture or, if no interest was so
payable, at the rate of (pound)5 per centum per annum


<PAGE>

                                                                              13


from the date of forfeiture until payment but the Directors may waive payment
wholly or in part or enforce payment without any allowance for the value of the
shares at the time of forfeiture or for any consideration received on their
disposal.

28. A statutory declaration by a Director or the secretary that a share has been
forfeited on a specified date shall be conclusive evidence of the facts stated
in it as against all persons claiming to be entitled to the share and the
declaration shall (subject to the execution of an instrument of transfer if
necessary) constitute a good title to the share and the person to whom the share
is disposed of shall not be bound to see to the application of the
consideration, if any, nor shall his title to the share be affected by any
irregularity in or invalidity of the proceedings in reference to the forfeiture
or disposal of the share.


                               TRANSFER OF SHARES

29. The instrument of transfer of a share may be in any usual form or in any
other form which the Directors may approve and shall be executed by or on behalf
of the transferor and, unless the share is fully paid, by or on behalf of the
transferee.

30. No transfer of any share in the capital of the Company to any person not
already a member of the Company shall be made or registered without the previous
sanction of the Directors, who may without assigning any reason, decline to give
any such sanction. The Directors may also suspend the registration of transfers
during the fourteen days immediately preceding the Ordinary General Meeting in
each year. The Directors may decline to recognise any instrument of transfer
unless accompanied by the certificate of the shares to which it relates, and
such other evidence as the Directors may reasonably require to show the right of
the transferor to make the transfer. The Directors may decline to register a
transfer of any shares on which the Company has a lien. If the Directors refuse
to register a transfer of any share they


<PAGE>

                                                                              14


shall within two months after the date on which the transfer was lodged with the
Company send to the transferee notice of the refusal as required by section 67
of the Act.

31. The Company shall be entitled to retain any instrument of transfer which is
registered, but any instrument of transfer which the Directors refuse to
register shall be returned to the person lodging it when notice of the refusal
is given.


                             TRANSMISSION OF SHARES

32. If a member dies the survivor or survivors where he was a joint holder, and
his personal representatives where he was a sole holder or the only survivor of
joint holders, shall be the only persons recognised by the Company as having any
title to his interest; but nothing herein contained shall release the estate of
a deceased member from any liability in respect of any share which had been
jointly held by him.

33. A person becoming entitled to a share in consequence of the death or
bankruptcy of a member may, upon such evidence being produced as the Directors
may properly require, elect either to become the holder of the share or to have
some person nominated by him registered as the transferee. If he elects to
become the holder he shall give notice to the Company to that effect. If he
elects to have another person registered he shall execute an instrument of
transfer of the share to that person. All articles relating to the transfer of
shares shall apply to the notice or instrument of transfer as if it were an
instrument of transfer executed by the member and the death or bankruptcy of the
member had not occurred.

34. A person becoming entitled to a share in consequence of the death or
bankruptcy of a member shall have the rights to which he would be entitled if he
were the holder of the share, except that he shall not, before being registered
as the holder


<PAGE>

                                                                              15


of the share, be entitled in respect of it to attend or vote at any meeting of
the Company or at any separate meeting of the holders of any class of shares in
the Company.


                           ALTERATION OF SHARE CAPITAL

35. The Company may by ordinary resolution -

                  (a) increase its share capital by new shares of such amount as
                  the resolution prescribes;

                  (b) consolidate and divide all or any or its share capital
                  into shares of larger amount than its existing shares;

                  (c) subject to the provisions of the Act, sub-divide its
                  shares, or any of them, into shares of smaller amount and the
                  resolution may determine that, as between the shares resulting
                  from the sub-division, any of them may have any preference or
                  advantage as compared with the others; and

                  (d) cancel shares which, at the date of the passing of the
                  resolution, have not been taken or agreed to be taken by any
                  person and diminish the amount of its share capital by the
                  amount of the shares so cancelled.

36. Whenever as a result of a consolidation of shares any members would become
entitled to fractions of a share, the Directors may, instead of issuing the
fractions of a share, on behalf of those members, sell the shares representing
the fractions for the best price reasonably obtainable to any person (including,
subject to the provisions of the Act, the Company) and distribute the net
proceeds of sale in due proportion among those members, and the Directors may
authorise some person to execute an instrument of transfer of the shares to, or
in accordance with the directions of, the purchaser. The


<PAGE>

                                                                              16


transferee shall not be bound to see to the application of the purchase money
nor shall his title to the shares be affected by any irregularity in or
invalidity of the proceedings in reference to the sale.

37. Subject to the provisions of the Act, the Company may by special resolution
reduce its share capital, any capital redemption reserve and any share premium
account in any way.


                         CONVERSION OF SHARES INTO STOCK

38. The Company may by ordinary resolution convert any paid-up shares into stock
and reconvert any stock into paid-up shares of any denomination.

39. The holders of stock may transfer the same, or any part thereof, in the same
manner, and subject to the same regulations, as, and subject to which, the
shares from which the stock arose might previously to conversion have been
transferred, or as near thereto as circumstances admit; but the Directors may
from time to time fix the minimum amount of stock transferable and restrict or
forbid the transfer of fractions of that minimum, but the minimum shall not
exceed the nominal amount of the shares from which the stock arose.

40. The holders of stock shall, according to the amount of the stock held by
them, have the same rights, privileges and advantages as regards dividends,
voting at meetings of the Company and other matters as if they held the shares
from which the stock arose, but no such privilege or advantage (except
participation in the dividends and profits of the Company) shall be conferred by
any such aliquot part of stock as would not, if existing in shares, have
conferred that privilege or advantage.


<PAGE>

                                                                              17


41. Such of the regulations of the Company as are applicable to paid-up shares
shall apply to stock and the words "shares" and "shareholder" therein shall
include "stock" and "stockholder".


                         REDEMPTION OF PREFERENCE SHARES

42. Subject to the provisions of the Act, the redemption of redeemable
preference shares shall be effected on such terms and in such manner, as may be
provided by the articles.


                                GENERAL MEETINGS

43. All general meetings other than annual general meetings shall be called
extraordinary general meetings.

44. The Directors may call general meetings, and on the requisition of a member
pursuant to the provisions of the Act, shall forthwith proceed to convene an
extraordinary general meeting for a date not later than eight weeks after
receipt of the requisition. If there are not within the Isle of Man sufficient
Directors to call a general meeting, any Director or any member of the Company
may call a general meeting.


                           NOTICE OF GENERAL MEETINGS

45. An annual general meeting and an extraordinary general meeting called for
the passing of a special resolution or a resolution appointing a person as a
Director shall be called by at least twenty-one clear days' notice. All other
extraordinary general


<PAGE>

                                                                              18



meetings shall be called by at least fourteen clear days' notice but a general
meeting may be called by shorter notice if it is so agreed -

                  (a) In the case of an annual general meeting, by all the
                  members entitled to attend and vote thereat; and

                  (b) In the case of any other meeting by a majority in number
                  of the members having a right to attend and vote being a
                  majority together holding not less than ninety five per cent
                  in nominal value of the shares giving that right.

The notice shall specify the time and place of the meeting and the general
nature of the business to be transacted and, in the case of an annual general
meeting, shall specify the meeting as such.

Subject to the provisions of the articles and to any restrictions imposed on any
shares, the notice shall be given to all the members, to all persons entitled to
a share in consequence of the death or bankruptcy of a member and to the
Directors and auditors.

46. The accidental omission to give notice of a meeting to or the non-receipt of
notice of a meeting by any person entitled to receive notice shall not
invalidate the proceedings at that meeting.


                         PROCEEDINGS AT GENERAL MEETINGS

47. No business shall be transacted at any meeting unless a quorum is present.
Two persons entitled to vote upon the business to be transacted, each being a
member or a proxy for a member or a duly authorised representative of a
corporation which is a member, shall be a quorum. When the Company has a single
member, the member


<PAGE>

                                                                              19


or the proxy for the member or a duly authorised representative of the
corporation which is the member, shall be a quorum.

48. If such a quorum is not present within half an hour from the time appointed
for the meeting or if during a meeting such a quorum ceases to be present, the
meeting shall stand adjourned to the same day in the next week at the same time
and place or to such time and place as the Directors may determine.

49. The Chairman, if any, of the Board of Directors or in his absence some other
Director nominated by the Directors shall preside as Chairman of the meeting,
but if neither the Chairman nor such other Director (if any) be present within
fifteen minutes after the time appointed for holding the meeting and willing to
act, the Directors present shall elect one of their number to be Chairman and if
there is only one Director present and willing to act, he shall be Chairman.

50. If no Director is willing to act as Chairman, or if no Director is present
within fifteen minutes after the time appointed for holding the meeting, the
members present and entitled to vote shall choose one of their number to be
Chairman.

51. A Director shall, notwithstanding that he is not a member, be entitled to
attend and speak at any general meeting and at any separate meeting of the
holders of any class of shares in the Company.

52. The Chairman may, with the consent of a meeting at which a quorum is present
(and shall if so directed by the meeting), adjourn the meeting from time to time
and from place to place, but no business shall be transacted at an adjourned
meeting other than business which might properly have been transacted at the
meeting had the adjournment not taken place. When a meeting is adjourned for
fourteen days or more, at least seven clear days' notice shall be given
specifying the time and place of the


<PAGE>

                                                                              20


adjourned meeting and the general nature of the business to be transacted.
Otherwise it shall not be necessary to give any such notice.

53. A resolution put to the vote of a meeting shall be decided on a show of
hands unless before, or on the declaration of the result of, the show of hands a
poll is duly demanded. Subject to the provisions of the Act, a poll may be
demanded -

         (a) by the Chairman; or

                  (b) by at least two members having the right to vote at the
                  meeting; or

                  (c) by a member or members representing no less than one-tenth
                  of the total voting rights of all the members having the right
                  to vote at the meeting; or

                  (d) by a member or members holding shares conferring a right
                  to vote at the meeting being shares on which an aggregate sum
                  has been paid up equal to not less than one-tenth of the total
                  sum paid up on all the shares conferring that right;

and a demand by a person as proxy for a member shall be the same as a demand by
the member.

54. Unless a poll is duly demanded a declaration by the Chairman that a
resolution has been carried or carried unanimously, or by a particular majority,
or lost, or not carried by a particular majority and an entry to that effect in
the minutes of the meeting shall be conclusive evidence of the fact without
proof of the number or proportion of the votes recorded in favour of or against
the resolution.


<PAGE>

                                                                              21


55. The demand for a poll may, before the poll is taken, be withdrawn but only
with the consent of the Chairman and a demand so withdrawn shall not be taken to
have invalidated the result of a show of hands declared before the demand was
made.

56. A poll shall be taken as the Chairman directs and he may appoint scrutineers
(who need not be members) and fix a time and place for declaring the result of
the poll. The result of the poll shall be deemed to be the resolution of the
meeting at which the poll was demanded.

57. In the case of an equality of votes, whether on a show of hands or on a
poll, the Chairman shall be entitled to a casting vote in addition to any other
vote he may have.

58. A poll demanded on the election of a Chairman or on a question of
adjournment shall be taken forthwith. A poll demanded on any other question
shall be taken either forthwith or at such time and place as the Chairman
directs not being more than thirty days after the poll is demanded. The demand
for a poll shall not prevent the continuance of a meeting for the transaction of
any business other than the question on which the poll was demanded. If a poll
is demanded before the declaration of the result of a show of hands and the
demand is duly withdrawn, the meeting shall continue as if the demand had not
been made.

59. No notice need be given of a poll not taken forthwith if the time and place
at which it is to be taken are announced at the meeting at which it is demanded.
In any other case at least seven clear days notice shall be given specifying the
time and place at which the poll is to be taken.

60. A resolution in writing executed by or on behalf of each member who would
have been entitled to vote upon it if it had been proposed at a general meeting
at which he was present shall be as effectual as if it had been passed at a
general meeting duly convened and held and may consist of several instruments in
the like form each


<PAGE>

                                                                              22


executed by or on behalf of one or more members, provided the provisions of
Section 118B of the Act are complied with and that such resolution is received
by the Company at its registered office within seven days of the date of its
execution in terms hereof.





                                VOTES OF MEMBERS

61. Subject to any rights or restrictions attached to any shares, on a show of
hands every member who (being an individual) is present in person or by proxy or
(being a corporation) is present by a duly authorised representative, not being
himself a member, shall have one vote and on a poll every member entitled to
vote shall have one vote for every share of which he is the holder.

62. In the case of joint holders the vote of the senior who tenders a vote,
whether in person or by proxy, shall be accepted to the exclusion of the votes
of the other joint holders; and seniority shall be determined by the order in
which the names of the holders stand in the register of members.

63. A member in respect of whom an order has been made by any court having
jurisdiction (whether in the Isle of Man or elsewhere) in matters concerning
mental disorder may vote, whether on a show of hands or on a poll, by his
receiver, curator bonis or other person authorised in that behalf appointed by
that court, and any such receiver, curator bonis or other person may, on a poll,
vote by proxy. Evidence to the satisfaction of the Directors of the authority of

any directions given by special resolution the business of the Company shall be
managed by the Directors who may exercise all the powers of the Company. No
alteration of the memorandum or articles and no such direction shall invalidate
any prior act of the Directors which would have been valid if that alteration
had not been made or that direction had not been given. The powers given by this
regulation shall not be limited by any special power given to the Directors by
the articles and a meeting of Directors at which a quorum is present may
exercise all powers exercisable by the Directors.

                                                                              28

of the members in General Meeting, such sum or sums of money for the purposes of
the Company's business as they may think fit and may secure the repayment of or
raise any such sum or sums as aforesaid in such manner and upon such terms and
conditions and in all other respects as they may think fit, and in particular by
mortgages, deeds of bond and security, or other charges upon the whole or any
part of the property and assets of the Company, present or future, including its
uncalled or unissued capital, or by the issue at such price as they may think
fit, of bonds or debentures or debenture stock of the Company, either charged
upon the whole or any part of the property and assets of the Company, or not so
charged, or in any other way that the Directors may think expedient, and the
Directors may issue debentures or debenture stock or paid-up shares to any
person or persons as consideration for the purchase of any goodwill, business or
property purchased by the Company.

80. The Directors may, by power of attorney or otherwise, appoint any person to
be the agent of the Company for such purposes and on such conditions as they
determine, including authority for the agent to delegate all or any of his
powers. The Company may exercise the powers conferred by Sections 32 and 104 of
the Companies Act, 1931 and those powers shall accordingly be exercisable by the
Directors.


                         DELEGATION OF DIRECTORS' POWERS

81. The Directors may delegate any of their powers to any committee consisting
of one or more Directors. They may also delegate to any Managing Director or any
Director holding any other executive office such of their powers as they
consider desirable to be exercised by him. Any such delegation may be made
subject to any conditions the Directors may impose and either collaterally with
or to the exclusion of their own powers and may be revoked or altered. Subject
to any such conditions, the

number of Directors. The Company may by special resolution remove any Director
or by ordinary resolution appoint any person to be a Director.

                      DIRECTORS' APPOINTMENTS AND INTERESTS

89. Subject to the provisions of the Act, the Directors may appoint one or more
of their number to the office of Managing Director or to any other executive
office under the Company and may enter into an agreement or arrangement with any
Director for his employment by the Company or for the provision by him of any
services outside the scope of the ordinary duties of a Director. Any such
appointment, agreement or arrangement may be made upon such terms as the
Directors determine and they may remunerate any such Director for his services
as they think fit. Any appointment of a Director to an executive office shall
terminate if he ceases to be a Director but without prejudice to any claim to
damages for breach of the contract of service between the Director and the
Company.

90. Subject to the provisions of the Act and provided that he has disclosed to
the Directors the nature and extent of any material interest of his, a Director
notwithstanding his office -


                  (a) may be a party to, or otherwise interested in, any
                  transaction or arrangement with the Company or in which the
                  Company is otherwise interested;

                  (b) may be a Director or other officer of, or employed by, or

                  interested in, any body corporate promoted by the Company or
                  in which the Company is otherwise interested; and

                  (c) shall not, by reason of his office, be accountable to the
                  Company for any benefit which he derives from any such office
                  or employment or


<PAGE>

                                                                              32


                  from any such transaction or arrangement or from any interest
                  in any such body corporate and no such transaction or
                  arrangement shall be liable to be avoided on the ground of any
                  such interest or benefit.

91. For the purposes of the foregoing article -

                  (a) a general notice given to the Directors that a Director is
                  to be regarded as having an interest of the nature and extent
                  specified in the notice in any transaction or arrangement in
                  which a specified person or class of persons is interested
                  shall be deemed to be a disclosure that the Director has an
                  interest in any such transaction of the nature and extent so
                  specified; and

                  (b) an interest of which a Director has no knowledge and of
                  which it is unreasonable to expect him to have knowledge shall
                  not be treated as an interest of his.

92. Subject to article 90 hereof and the Act if the Company is a single member
company and having one member it enters into a contract with the sole member
otherwise than in the ordinary course of the Company's business and the sole
member is also a director of the Company, the Company should, unless the
contract is in writing, ensure that the terms of the contract are either set out
in a written memorandum or are recorded in the minutes of the first meeting of
the directors of the Company following the making of the contract.


                       DIRECTORS' GRATUITIES AND PENSIONS

who has held but no longer holds any executive office or employment with the
Company or with any body corporate which is or has been a subsidiary of the
Company or a predecessor of the Company or of any such subsidiary and for any
member of his family (including a spouse and a former spouse) or any person who
is or was dependent on him, and may (as well before as after he ceases to hold
such office or employment) contribute to any fund and pay premiums for the
purchase or provision of any such benefit.


                            PROCEEDINGS OF DIRECTORS

94. Subject to the provisions of the articles, the Directors may regulate their
proceedings as they think fit. A Director may, and the secretary at the request
of a Director shall, call a meeting of the Directors. Questions arising at a
meeting shall be decided by a majority of votes. In the case of an equality of
votes, the Chairman shall have a second or casting vote. A Director who is also
an alternate Director shall be entitled in the absence of his appointor to a
separate vote on behalf of his appointor in addition to his own vote.

95. The quorum for the transaction of the business of the Directors may be fixed
by the Directors and unless so fixed at any other number shall be two. A person
who holds office only as an alternate Director shall, if his appointor is not
present, be counted in the quorum.

96. The continuing Directors or a sole continuing Director may act
notwithstanding any vacancies in their number, but, if the number of Directors
is less than the number fixed as the quorum, the continuing Directors or
Director may act only for the purpose of filling vacancies or of calling a
general meeting.

                                                                              34


97. The Directors may appoint one of their number to be the Chairman of the
Board of Directors and may at any time remove him from that office. Unless he is
unwilling to do so, the Director so appointed shall preside at every meeting of
Directors at which he is present. But if there is no Director holding that
office, or if the Director holding it is unwilling to preside or is not present
within five minutes after the time appointed for the meeting, the Directors
present may appoint one of their number to be Chairman of the meeting.

98. All acts done by a meeting of Directors, or of a committee of Directors, or
by a person acting as a Director shall, notwithstanding that it be afterwards
discovered that there was a defect in the appointment of any Director or that
any of them were disqualified from holding office, or had vacated office, or
were not entitled to vote, be valid as if every such person had been duly
appointed and was qualified and had continued to be a Director and had been
entitled to vote.

99. A resolution in writing signed by all the Directors entitled to receive
notice of a meeting of Directors or of a committee of Directors shall be as
valid and effectual as if it had been passed at a meeting of Directors or (as
the case may be) a committee of Directors duly convened and held and may consist
of several documents in the like form each signed by one or more Directors, but
a resolution signed by an alternate need not also be signed by his appointor
and, if it is signed by a Director who has appointed an alternate Director, it
need not be signed by the alternate Director in that capacity.

100. Save as otherwise provided by the articles, a Director shall not vote at a
meeting of Directors or of a committee of Directors on any resolution concerning
a matter in which he has, directly or indirectly, an interest or duty which is
material and which conflicts or may conflict with the interest of the Company
unless he has declared the nature of his interest in the manner required by
Section 148 of the Act.

101. A Director shall not be counted in the quorum present at a meeting in
relation to a resolution on which he is not entitled to vote.

102. The Company may by ordinary resolution suspend or relax to any extent,
either generally or in respect of any particular matter, any provision of the
articles prohibiting a Director from voting at a meeting of Directors or of a
committee of Directors.

103. If a question arises at a meeting of Directors or of a committee of
Directors as to the right of a Director to vote, the question may, before the
conclusion of the meeting, be referred to the Chairman of the meeting and his
ruling in relation to any Director other than himself shall be final and
conclusive.

104. Any Director or member of a committee of the Directors may participate in a
meeting of the Directors or such committee by means of telephonic or similar
communications whereby all persons participating in the meeting can hear each
other and participation in a meeting in this manner shall be deemed to
constitute presence in person at such meeting. The location of such a telephonic
meeting shall be deemed to be the place at which the Chairman of the meeting was
located at the time of the meeting.




                             MANAGEMENT AND CONTROL

105. The management and control of the business of the Company shall be in and

                  holders of any class of shares in the Company and of the
                  Directors, and of committees of Directors, including the names
                  of the Directors present at such meeting.

who shall sign any instrument to which the seal is affixed and unless otherwise
so determined it shall be signed by a Director and by the secretary or by a
second Director.

                                    DIVIDENDS

110. Subject to the provisions of the Act, the Company may by ordinary
resolution declare dividends in accordance with the respective rights of the
members, but no dividend shall exceed the amount recommended by the Directors.

111. Subject to the provisions of the Act, the Directors may pay interim
dividends if it appears to them that they are justified by the profits of the
Company available for distribution. If the share capital is divided into
different classes, the Directors may pay interim dividends on shares which
confer deferred or non-preferred rights with regard to dividend as well as on
shares which confer preferential rights with regard to dividend, but no interim
dividend shall be paid on shares carrying deferred or non-preferential rights
if, at the time of payment, any preferential dividend is in arrear. The
Directors may also pay at intervals settled by them any dividend payable at a
fixed rate if it appears to them that the profits available for distribution
justify the payment. Provided the Directors act in good faith they shall not
incur any liability to the holders of shares conferring preferred rights for any
loss they may suffer by the lawful payment of an interim dividend on any shares
having deferred or non-preferred rights.

112. Except as otherwise provided by the rights attached to shares, all
dividends shall be declared and paid according to the amounts paid up on the
shares on which the dividend is paid. All dividends shall be apportioned and
paid proportionately to the amounts paid up on the shares during any portion or
portions of the period in respect of which the dividend is paid; but, if any
share is issued on terms providing that it shall rank for dividend as from a
particular date, that share shall rank for dividend accordingly.

113. A general meeting declaring a dividend may, upon the recommendation of the
Directors, direct that it shall be satisfied wholly or partly by the
distribution of assets


<PAGE>

                                                                              38


and where any difficulty arises in regard to the distribution, the Directors may
settle the same and in particular may issue fractional certificates and fix the
value for distribution of any assets and may determine that cash shall be paid
to any member upon the footing of the value so fixed in order to adjust the
rights of members and may vest any assets in trustees.

114. Any dividend or other moneys payable in respect of a share may be paid by
cheque sent by post to the registered address of the person entitled or, if two
or more persons are the holders of the share or are jointly entitled to it by
reason of the death or bankruptcy of the holder, to the registered address of
that one of those persons who is first named in the register of members or to
such person and to such address as the person or persons entitled may in writing
direct. Every cheque shall be made payable to the order of the person or persons
entitled or to such other person as the person or persons entitled may in
writing direct and payment of the cheque shall be a good discharge to the
Company. Any joint holder or other person jointly entitled to a share as
aforesaid may give receipts for any dividend or other moneys payable in respect
of the share.

115. No dividend or other moneys payable in respect of a share shall bear
interest against the Company unless otherwise provided by the rights attached to
the share.

116. Any dividend which has remained unclaimed for twelve years from the date
when it became due for payment shall, if the Directors so resolve, be forfeited
and cease to remain owing by the Company.


                                    ACCOUNTS

117.              (a) No member shall (as such) have any right of inspecting any
                  accounting records or other book or document of the Company
                  except as


<PAGE>

                                                                              39


                  conferred by statute or authorised by the Directors or by
                  ordinary resolution of the Company.

                  (b) The Company shall prepare such accounts as may be required
                  by the Act and the laws of the Isle of Man.

                  (c) Subject to the Act and the laws of the Isle of Man the
                  Company may elect to dispense with compliance with the
                  requirements of the Act which relate to the audit of the
                  accounts of the Company.


                            CAPITALISATION OF PROFITS

118. The Directors may with the authority of an ordinary resolution of the
Company -

                  (a) subject as hereinafter provided, resolve to capitalise any
                  undivided profits of the Company not required for paying any
                  preferential dividend (whether or not they are available for
                  distribution) or any sum standing to the credit of the
                  Company's share premium account or capital redemption reserve;

                  (b) appropriate the sum resolved to be capitalised to the
                  members who would have been entitled to it if it were
                  distributed by way of dividend and in the same proportions and
                  apply such sum on their behalf either in or towards paying up
                  the amounts, if any, for the time being unpaid on any shares
                  held by them respectively, or in paying up in full unissued
                  shares or debentures of the Company of a nominal amount, equal
                  to that sum, and allot the shares or debentures credited as
                  fully paid to those members, or as they may direct, in those
                  proportions, or partly in one way and partly in the other: but
                  the share premium account, the capital


<PAGE>

                                                                              40


                  redemption reserve and any profits which are not available for
                  distribution may, for the purposes of this regulation, only be
                  applied in paying up unissued shares to be allotted to members
                  credited as fully paid;

                  (c) make such provision by the issue of fractional
                  certificates or by payment in cash or otherwise as they
                  determine in the case of shares or debentures becoming
                  distributable under this regulation in fractions; and

                  (d) authorise any person to enter on behalf of all the members
                  concerned into an agreement with the Company providing for the
                  allotment to them respectively, credited as fully paid, of any
                  shares or debentures to which they are entitled upon such
                  capitalisation, any agreement made under such authority being
                  binding on all such members.


                                     NOTICES

119. Any notice to be given to or by any person pursuant to the articles shall
be in writing except that a notice calling a meeting of the Directors need not
be in writing.

120. The Company may give any notice to a member either personally or by sending
it by post in a prepaid envelope addressed to the member at his registered
address or by leaving it at that address. In the case of joint holders of a
share, all notices shall be given to the joint holder whose name stands first in
the register of members in respect of the joint holding and notice so given
shall be sufficient notice to all the joint holders. A member whose registered
address is not within the British Islands and who gives to the Company an
address within the British Islands at which notices may be given to him shall be
entitled to have notices given to him at that address, but otherwise no such
member shall be entitled to receive any notice from the Company.


<PAGE>

                                                                              41


121. A member present, either in person or by proxy, at any meeting of the
Company or of the holders of any class of shares in the Company shall be deemed
to have received notice of the meeting and, where requisite, of the purposes for
which it was called.

122. Every person who becomes entitled to a share shall be bound by any notice
in respect of that share which, before his name is entered in the register of
members, has been duly given to a person from whom he derives his title.

123. Proof that an envelope containing a notice was properly addressed, prepaid
and posted shall be conclusive evidence that the notice was given. A notice
shall be deemed to be given at the expiration of 48 hours after the envelope
containing it was posted.

124. A notice may be given by the Company to the persons entitled to a share in
consequence of the death or bankruptcy of a member by sending or delivering it,
in any manner authorised by the articles for the giving of notice to a member,
addressed to them by name, or by the title of representatives of the deceased,
or trustee of the bankrupt or by any like description at the address, if any,
within the British Islands supplied for that purpose by the persons claiming to
be so entitled. Until such an address has been supplied, a notice may be given
in any manner in which it might have been given if the death or bankruptcy had
not occurred.


                                   WINDING UP

125. If the Company is wound up, the liquidator may, with the sanction of an
extraordinary resolution of the Company and any other sanction required by the
Act, divide among the members in specie the whole or any part of the assets of
the Company and may, for that purpose, value any assets and determine how the
division


<PAGE>

                                                                              42


shall be carried out as between the members or different classes of members. The
liquidator may, with the like sanction, vest the whole or any part of the assets
in trustees upon such trusts for the benefit of the members as he with the like
sanction determines, but no member shall be compelled to accept any assets upon
which there is a liability.


                                    INDEMNITY

126. Every Director or other officer of the Company shall be entitled to be
indemnified out of the assets of the Company against all losses or liabilities
(including any such liability as is mentioned in paragraph (c) of the proviso to
Section 151 of the Act) which he may sustain or incur in or about the execution
of the duties of his office or otherwise in relation thereto, and no Director or
other officer shall be liable for any loss, damage or misfortune which may
happen to or be incurred by the Company in the execution of the duties of his
office or in relation thereto. But this Article shall only have effect in so far
as its provisions are not avoided by the said Section.

127. The Company may purchase and maintain indemnity insurance for the benefit
of each Director or other officer of the Company.

                                                                               7


(3) In these regulations, unless there is something in the subject of context
inconsistent with such construction:-

                  (a) words importing the plural number shall be deemed to
                  include the singular number and words importing the singular
                  number shall be deemed to include the plural number;

                  (b) words importing the masculine gender only include the

substitution therefor.


                                  SHARE CAPITAL

5.       (1) Subject to the provisions of the Act and without prejudice to any
         rights attached to any existing shares, any share may be issued with
         such rights or restrictions as the Company may by ordinary resolution
         determine.

         (2) Subject to the provisions of the Act, shares may be issued in
         fractional denominations to the same extent as whole shares.

6. Subject to the provisions of the Act and the articles, redeemable preference
shares may be issued on such terms and in such manner as may be provided by the
articles.


<PAGE>

                                                                               8


7. The Company may exercise the powers of paying commissions conferred by the
Act. Subject to the provisions of the Act, any such commissions may be satisfied
by the payment of cash or by the allotment of fully or partly paid shares or
partly in one way and partly in the other.

8. Except as required by law, no person shall be recognised by the Company as
holding any share upon any trust and (except as otherwise provided by the
articles or by law) the Company shall not be bound by or recognise any interest
in any share except an absolute right to the entirety thereof in the holder.

9. The shares shall be at the disposal of the Directors, and (save as otherwise
directed by the Company in General Meeting) they may allot or otherwise dispose
of them to such persons at such times and generally on such terms and conditions
as they think proper, subject nevertheless to article 2 and provided that no
shares shall be issued at a discount, except as provided by Section 47 of the
Act.

10. If at any time the share capital is divided into different classes of
shares, the rights attached to any class (unless otherwise provided by the terms
of issue of the shares of that class) may be varied with the consent in writing
of the holders of all of the issued shares of that class, or with the sanction
of an extraordinary resolution passed at a separate general meeting of the
holders of the shares of the class. To every such separate general meeting the
provisions of these regulations relating to general meetings shall in the case
of the number of holders of a particular class of shares being two or more
mutatis mutandis apply, but so that the necessary quorum shall be two persons at
least holding or representing by proxy one-third of the issued shares of the
class, and that any holder of shares of the class present in person or by proxy
may demand a poll. In the case of the number of holders of a particular class of
shares being one, one person holding or representing all the issued shares of
the class shall be a quorum.

                                                                               9


11. The Company may issue share warrants to bearer in respect of any fully
paid-up shares of the Company, stating that the bearer of the warrant is
entitled to the shares therein specified. Such warrants shall be issued upon
such terms and subject to such conditions as may be resolved upon by the
Directors. Subject to the provisions of the Act and of these articles the holder
of a share warrant shall be deemed to be a member of the Company and shall be
entitled to the same rights and privileges as he would have had if his name had
been included in the share register of the Company as the holder of the shares.


                               SHARE CERTIFICATES

12.      (1) Every member, upon becoming the holder of any shares shall be
         entitled

                  (a) without payment, to one certificate for all the shares of
                  each class held by him (and, upon transferring a part of his
                  holding of shares of any class, to a certificate for the
                  balance of such holding); or

                  (b) to several certificates each for one or more of his shares
                  upon payment, for every certificate after the first, of such
                  reasonable sum as the Directors may determine.

         (2) Every certificate shall be sealed with the seal and shall specify
         the number, class and distinguishing numbers (if any) of the shares to
         which it relates and the amount or respective amounts paid up thereon.

         (3) The Company shall not be bound to issue more than one certificate
         for shares held jointly by several persons and delivery of a
         certificate to one joint holder shall be a sufficient delivery to all
         of them.


<PAGE>

                                                                              10


13. If a share certificate is defaced, worn-out, lost or destroyed, it may be
renewed on such terms (if any) as to evidence and indemnity and payment of the
expenses reasonably incurred by the Company in investigating evidence as the
Directors may determine but otherwise free of charge, and (in the case of
defacement or wearing-out) on delivery up of the old certificate.

14. The Company shall have a first and paramount lien on every share for all
moneys (whether presently payable or not) payable at a fixed time or called in
respect of that share. The Directors may at any time declare any share to be
wholly or in part exempt from the provisions of this regulation. The Company's
lien on a share shall extend to any amount payable in respect of it.

15. The Company may sell in such manner as the Directors determine any shares on
which the Company has a lien if a sum in respect of which the lien exists is
presently payable and is not paid within fourteen clear days after notice has
been given to the holder of the share or to the person entitled to it in
consequence of the death or bankruptcy of the holder, demanding payment and
stating that if the notice is not complied with the shares may be sold.

16. To give effect to a sale the Directors may authorise some person to execute
an instrument of transfer of the shares, sold to, or in accordance with the
directions of, the purchaser. The title of the transferee to the shares shall
not be affected by any irregularity in or invalidity of the proceedings in
reference to the sale.

17. The net proceeds of the sale, after payment of the costs, shall be applied
in payment of so much of the sum for which the lien exists as is presently
payable, and any residue shall (upon surrender to the Company for cancellation
of the certificate for the shares sold and subject to a like lien for any moneys
not presently payable as existed upon the shares before the sale) be paid to the
person entitled to the shares at the date of the sale.

                         CALLS ON SHARES AND FORFEITURE

18. Subject to the terms of allotment, the Directors may make calls upon the
members in respect of any moneys unpaid on their shares (whether in respect of
nominal value or premium) and each member shall (subject to receiving at least
fourteen clear days notice specifying when and where payment is to be made) pay
to the Company as required by the notice the amount called on his shares. A call
may be required to be paid by instalments. A call may, before receipt by the
Company of any sum due thereunder, be revoked in whole or in part and payment of
a call may be postponed in whole or in part. A person upon whom a call is made
shall remain liable for calls made upon him notwithstanding the subsequent
transfer of the shares in respect whereof the call was made.

19. A call shall be deemed to have been made at the time when the resolution of
the Directors authorising the call was passed.

20. The joint holders of a share shall be jointly and severally liable to pay
all calls in respect thereof.

21. If a call remains unpaid after it has become due and payable the person from
whom it is due and payable shall pay interest on the amount unpaid from the day
it became due and payable until it is paid at the rate fixed by the terms of
allotment of the share or in the notice of the call or, if no rate is fixed, at
the rate of (pound)5 per centum per annum but the Directors may waive payment of
the interest wholly or in part.

22. An amount payable in respect of a share on allotment or at any fixed date,
whether in respect of nominal value or premium or as an instalment of a call,
shall be deemed to be a call and if it is not paid the provisions of the
articles shall apply as if that amount had become due and payable by virtue of a
call.


<PAGE>

                                                                              12


23. Subject to the terms of allotment, the Directors may make arrangements on
the issue of shares for a difference between the holders in the amounts and
times of payment of calls on their shares.

24. If a call remains unpaid after it has become due and payable the Directors
may give to the person from whom it is due not less than fourteen clear days'
notice requiring payment of the amount unpaid together with any interest which
may have accrued. The notice shall name the place where payment is to be made
and shall state that if the notice is not complied with the shares in respect of
which the call was made will be liable to be forfeited.

25. If the notice is not complied with any share in respect of which it was
given may, before the payment required by the notice has been made, be forfeited
by a resolution of the Directors and the forfeiture shall include all dividends
or other moneys payable in respect of the forfeited shares and not paid before
the forfeiture.

26. Subject to the provisions of the Act, a forfeited share may be sold,
re-allotted or otherwise disposed of on such terms and in such manner as the
Directors determine either to the person who was before the forfeiture the
holder or to any other person and at any time before sale, re-allotment or other
disposition, the forfeiture may be cancelled on such terms as the Directors
think fit. Where for the purposes of its disposal a forfeited share is to be
transferred to any person the Directors may authorise some person to execute an
instrument of transfer of the share to that person.

27. A person any of whose shares have been forfeited shall cease to be a member
in respect of them and shall surrender to the Company for cancellation the
certificate for the shares forfeited but shall remain liable to the Company for
all moneys which at the date of forfeiture were presently payable by him to the
Company in respect of those shares with interest at the rate at which interest
was payable on those moneys before the forfeiture or, if no interest was so
payable, at the rate of (pound)5 per centum per annum


<PAGE>

                                                                              13


from the date of forfeiture until payment but the Directors may waive payment
wholly or in part or enforce payment without any allowance for the value of the
shares at the time of forfeiture or for any consideration received on their
disposal.

28. A statutory declaration by a Director or the secretary that a share has been
forfeited on a specified date shall be conclusive evidence of the facts stated
in it as against all persons claiming to be entitled to the share and the
declaration shall (subject to the execution of an instrument of transfer if
necessary) constitute a good title to the share and the person to whom the share
is disposed of shall not be bound to see to the application of the
consideration, if any, nor shall his title to the share be affected by any
irregularity in or invalidity of the proceedings in reference to the forfeiture
or disposal of the share.


                               TRANSFER OF SHARES

29. The instrument of transfer of a share may be in any usual form or in any
other form which the Directors may approve and shall be executed by or on behalf
of the transferor and, unless the share is fully paid, by or on behalf of the
transferee.

30. No transfer of any share in the capital of the Company to any person not
already a member of the Company shall be made or registered without the previous
sanction of the Directors, who may without assigning any reason, decline to give
any such sanction. The Directors may also suspend the registration of transfers
during the fourteen days immediately preceding the Ordinary General Meeting in
each year. The Directors may decline to recognise any instrument of transfer
unless accompanied by the certificate of the shares to which it relates, and
such other evidence as the Directors may reasonably require to show the right of
the transferor to make the transfer. The Directors may decline to register a
transfer of any shares on which the Company has a lien. If the Directors refuse
to register a transfer of any share they


<PAGE>

                                                                              14


shall within two months after the date on which the transfer was lodged with the
Company send to the transferee notice of the refusal as required by section 67
of the Act.

31. The Company shall be entitled to retain any instrument of transfer which is
registered, but any instrument of transfer which the Directors refuse to
register shall be returned to the person lodging it when notice of the refusal
is given.


                             TRANSMISSION OF SHARES

32. If a member dies the survivor or survivors where he was a joint holder, and
his personal representatives where he was a sole holder or the only survivor of
joint holders, shall be the only persons recognised by the Company as having any
title to his interest; but nothing herein contained shall release the estate of
a deceased member from any liability in respect of any share which had been
jointly held by him.

33. A person becoming entitled to a share in consequence of the death or
bankruptcy of a member may, upon such evidence being produced as the Directors
may properly require, elect either to become the holder of the share or to have
some person nominated by him registered as the transferee. If he elects to
become the holder he shall give notice to the Company to that effect. If he
elects to have another person registered he shall execute an instrument of
transfer of the share to that person. All articles relating to the transfer of
shares shall apply to the notice or instrument of transfer as if it were an
instrument of transfer executed by the member and the death or bankruptcy of the
member had not occurred.

34. A person becoming entitled to a share in consequence of the death or
bankruptcy of a member shall have the rights to which he would be entitled if he
were the holder of the share, except that he shall not, before being registered
as the holder


<PAGE>

                                                                              15


of the share, be entitled in respect of it to attend or vote at any meeting of
the Company or at any separate meeting of the holders of any class of shares in
the Company.


                           ALTERATION OF SHARE CAPITAL

35. The Company may by ordinary resolution -

                  (a) increase its share capital by new shares of such amount as
                  the resolution prescribes;

                  (b) consolidate and divide all or any or its share capital
                  into shares of larger amount than its existing shares;

                  (c) subject to the provisions of the Act, sub-divide its
                  shares, or any of them, into shares of smaller amount and the
                  resolution may determine that, as between the shares resulting
                  from the sub-division, any of them may have any preference or
                  advantage as compared with the others; and

                  (d) cancel shares which, at the date of the passing of the
                  resolution, have not been taken or agreed to be taken by any
                  person and diminish the amount of its share capital by the
                  amount of the shares so cancelled.

36. Whenever as a result of a consolidation of shares any members would become
entitled to fractions of a share, the Directors may, instead of issuing the
fractions of a share, on behalf of those members, sell the shares representing
the fractions for the best price reasonably obtainable to any person (including,
subject to the provisions of the Act, the Company) and distribute the net
proceeds of sale in due proportion among those members, and the Directors may
authorise some person to execute an instrument of transfer of the shares to, or
in accordance with the directions of, the purchaser. The


<PAGE>

                                                                              16


transferee shall not be bound to see to the application of the purchase money
nor shall his title to the shares be affected by any irregularity in or
invalidity of the proceedings in reference to the sale.

37. Subject to the provisions of the Act, the Company may by special resolution
reduce its share capital, any capital redemption reserve and any share premium
account in any way.


                         CONVERSION OF SHARES INTO STOCK

38. The Company may by ordinary resolution convert any paid-up shares into stock
and reconvert any stock into paid-up shares of any denomination.

39. The holders of stock may transfer the same, or any part thereof, in the same
manner, and subject to the same regulations, as, and subject to which, the
shares from which the stock arose might previously to conversion have been
transferred, or as near thereto as circumstances admit; but the Directors may
from time to time fix the minimum amount of stock transferable and restrict or
forbid the transfer of fractions of that minimum, but the minimum shall not
exceed the nominal amount of the shares from which the stock arose.

40. The holders of stock shall, according to the amount of the stock held by
them, have the same rights, privileges and advantages as regards dividends,
voting at meetings of the Company and other matters as if they held the shares
from which the stock arose, but no such privilege or advantage (except
participation in the dividends and profits of the Company) shall be conferred by
any such aliquot part of stock as would not, if existing in shares, have
conferred that privilege or advantage.


<PAGE>

                                                                              17


41. Such of the regulations of the Company as are applicable to paid-up shares
shall apply to stock and the words "shares" and "shareholder" therein shall
include "stock" and "stockholder".


                         REDEMPTION OF PREFERENCE SHARES

42. Subject to the provisions of the Act, the redemption of redeemable
preference shares shall be effected on such terms and in such manner, as may be
provided by the articles.


                                GENERAL MEETINGS

43. All general meetings other than annual general meetings shall be called
extraordinary general meetings.

44. The Directors may call general meetings, and on the requisition of a member
pursuant to the provisions of the Act, shall forthwith proceed to convene an
extraordinary general meeting for a date not later than eight weeks after
receipt of the requisition. If there are not within the Isle of Man sufficient
Directors to call a general meeting, any Director or any member of the Company
may call a general meeting.


                           NOTICE OF GENERAL MEETINGS

45. An annual general meeting and an extraordinary general meeting called for
the passing of a special resolution or a resolution appointing a person as a
Director shall be called by at least twenty-one clear days' notice. All other
extraordinary general


<PAGE>

                                                                              18


meetings shall be called by at least fourteen clear days' notice but a general
meeting may be called by shorter notice if it is so agreed -

                  (a) In the case of an annual general meeting, by all the
                  members entitled to attend and vote thereat; and

                  (b) In the case of any other meeting by a majority in number
                  of the members having a right to attend and vote being a
                  majority together holding not less than ninety five per cent
                  in nominal value of the shares giving that right.

The notice shall specify the time and place of the meeting and the general
nature of the business to be transacted and, in the case of an annual general
meeting, shall specify the meeting as such.

Subject to the provisions of the articles and to any restrictions imposed on any
shares, the notice shall be given to all the members, to all persons entitled to
a share in consequence of the death or bankruptcy of a member and to the
Directors and auditors.

46. The accidental omission to give notice of a meeting to or the non-receipt of
notice of a meeting by any person entitled to receive notice shall not
invalidate the proceedings at that meeting.


                         PROCEEDINGS AT GENERAL MEETINGS

47. No business shall be transacted at any meeting unless a quorum is present.
Two persons entitled to vote upon the business to be transacted, each being a
member or a proxy for a member or a duly authorised representative of a
corporation which is a member, shall be a quorum. When the Company has a single
member, the member


<PAGE>

                                                                              19


or the proxy for the member or a duly authorised representative of the
corporation which is the member, shall be a quorum.

48. If such a quorum is not present within half an hour from the time appointed
for the meeting or if during a meeting such a quorum ceases to be present, the
meeting shall stand adjourned to the same day in the next week at the same time
and place or to such time and place as the Directors may determine.

49. The Chairman, if any, of the Board of Directors or in his absence some other
Director nominated by the Directors shall preside as Chairman of the meeting,
but if neither the Chairman nor such other Director (if any) be present within
fifteen minutes after the time appointed for holding the meeting and willing to
act, the Directors present shall elect one of their number to be Chairman and if
there is only one Director present and willing to act, he shall be Chairman.

50. If no Director is willing to act as Chairman, or if no Director is present
within fifteen minutes after the time appointed for holding the meeting, the
members present and entitled to vote shall choose one of their number to be
Chairman.

51. A Director shall, notwithstanding that he is not a member, be entitled to
attend and speak at any general meeting and at any separate meeting of the
holders of any class of shares in the Company.

52. The Chairman may, with the consent of a meeting at which a quorum is present
(and shall if so directed by the meeting), adjourn the meeting from time to time
and from place to place, but no business shall be transacted at an adjourned
meeting other than business which might properly have been transacted at the
meeting had the adjournment not taken place. When a meeting is adjourned for
fourteen days or more, at least seven clear days' notice shall be given
specifying the time and place of the


<PAGE>

                                                                              20


adjourned meeting and the general nature of the business to be transacted.
Otherwise it shall not be necessary to give any such notice.

53. A resolution put to the vote of a meeting shall be decided on a show of
hands unless before, or on the declaration of the result of, the show of hands a
poll is duly demanded. Subject to the provisions of the Act, a poll may be
demanded -

         (a) by the Chairman; or

                  (b) by at least two members having the right to vote at the
                  meeting; or

                  (c) by a member or members representing no less than one-tenth
                  of the total voting rights of all the members having the right
                  to vote at the meeting; or

                  (d) by a member or members holding shares conferring a right
                  to vote at the meeting being shares on which an aggregate sum
                  has been paid up equal to not less than one-tenth of the total
                  sum paid up on all the shares conferring that right;

and a demand by a person as proxy for a member shall be the same as a demand by
the member.

54. Unless a poll is duly demanded a declaration by the Chairman that a
resolution has been carried or carried unanimously, or by a particular majority,
or lost, or not carried by a particular majority and an entry to that effect in
the minutes of the meeting shall be conclusive evidence of the fact without
proof of the number or proportion of the votes recorded in favour of or against
the resolution.


<PAGE>

                                                                              21


55. The demand for a poll may, before the poll is taken, be withdrawn but only
with the consent of the Chairman and a demand so withdrawn shall not be taken to
have invalidated the result of a show of hands declared before the demand was
made.

56. A poll shall be taken as the Chairman directs and he may appoint scrutineers
(who need not be members) and fix a time and place for declaring the result of
the poll. The result of the poll shall be deemed to be the resolution of the
meeting at which the poll was demanded.

57. In the case of an equality of votes, whether on a show of hands or on a
poll, the Chairman shall be entitled to a casting vote in addition to any other
vote he may have.

58. A poll demanded on the election of a Chairman or on a question of
adjournment shall be taken forthwith. A poll demanded on any other question
shall be taken either forthwith or at such time and place as the Chairman
directs not being more than thirty days after the poll is demanded. The demand
for a poll shall not prevent the continuance of a meeting for the transaction of
any business other than the question on which the poll was demanded. If a poll
is demanded before the declaration of the result of a show of hands and the
demand is duly withdrawn, the meeting shall continue as if the demand had not
been made.

59. No notice need be given of a poll not taken forthwith if the time and place
at which it is to be taken are announced at the meeting at which it is demanded.
In any other case at least seven clear days notice shall be given specifying the
time and place at which the poll is to be taken.

60. A resolution in writing executed by or on behalf of each member who would
have been entitled to vote upon it if it had been proposed at a general meeting
at which he was present shall be as effectual as if it had been passed at a
general meeting duly convened and held and may consist of several instruments in
the like form each


<PAGE>

                                                                              22


executed by or on behalf of one or more members, provided the provisions of
Section 118B of the Act are complied with and that such resolution is received
by the Company at its registered office within seven days of the date of its
execution in terms hereof.





                                VOTES OF MEMBERS

61. Subject to any rights or restrictions attached to any shares, on a show of
hands every member who (being an individual) is present in person or by proxy or
(being a corporation) is present by a duly authorised representative, not being
himself a member, shall have one vote and on a poll every member entitled to
vote shall have one vote for every share of which he is the holder.

62. In the case of joint holders the vote of the senior who tenders a vote,
whether in person or by proxy, shall be accepted to the exclusion of the votes
of the other joint holders; and seniority shall be determined by the order in
which the names of the holders stand in the register of members.

63. A member in respect of whom an order has been made by any court having
jurisdiction (whether in the Isle of Man or elsewhere) in matters concerning
mental disorder may vote, whether on a show of hands or on a poll, by his
receiver, curator bonis or other person authorised in that behalf appointed by
that court, and any such receiver, curator bonis or other person may, on a poll,
vote by proxy. Evidence to the satisfaction of the Directors of the authority of
the person claiming to exercise the right to vote shall be deposited at the
office, or at such other place as is specified in accordance with the articles
for the deposit of instruments of proxy, not less than 48 hours before the time
appointed for holding the meeting or adjourned meeting at which


<PAGE>

                                                                              23


the right to vote is to be exercised and in default the right to vote shall not
be exercisable.

64. No member shall vote at any general meeting or at any separate meeting of
the holders of any class of shares in the Company, either in person or by proxy,
in respect of any share held by him unless all moneys presently payable by him
in respect of that share have been paid.

65. No objections shall be raised to the qualification of any voter except at
the meeting or adjourned meeting at which the vote objected to is tendered, and
every vote not disallowed at the meeting shall be valid. Any objection made in
due time shall be referred to the Chairman whose decision shall be final and
conclusive.

66. On a poll votes may be given either personally or by proxy. A member may
appoint more than one proxy to attend on the same occasion.

67. An instrument appointing a proxy shall be in writing, executed by or on
behalf of the appointor and shall be in the following form (or in a form as near
thereto as circumstances allow or in any other form which is usual or which the
Directors may approve) -

                  meeting or in any instrument of proxy sent out by the Company
                  in relation to the meeting not less than 48 hours before the
                  time for holding the meeting or adjourned meeting at which the
                  person named in the instrument proposes to vote; or

permitted shall be invalid.

70. A vote given or poll demanded by proxy or by the duly authorised
representative of a corporation shall be valid notwithstanding the previous
determination of the authority of the person voting or demanding a poll unless
notice of the determination was received by the Company at the office or at such
other place at which the instrument of proxy was duly deposited before the
commencement of the meeting or adjourned meeting at which the vote is given or
the poll demanded or (in the case of

a poll taken otherwise than on the same day as the meeting or adjourned meeting)
the time appointed for taking the poll.

71. Where the Company is a single member company and the sole member takes any
decision which may be taken by the Company in general meeting and which has
effect as if agreed by the Company in general meeting he shall subject to
article 60 provide the Company with a written record of that decision by
forwarding such record to the Company at its registered office within seven days
of the date upon which the decision was taken.

                                                                              27


a Director in his absence but shall not be entitled to receive any remuneration
from the Company for his services as an alternate Director.

75. An alternate Director shall cease to be an alternate Director if his
appointor ceases to be a Director; but, if a Director retires by rotation or
otherwise but is reappointed or deemed to have been reappointed at the meeting
at which he retires; any appointment of an alternate Director made by him which
was in force immediately prior to his retirement shall continue after his
reappointment.

76. Any appointment or removal of an alternate Director shall be by notice to
the Company signed by the Director making or revoking the appointment or in any
other manner approved by the Directors.

appointing him.


                               POWERS OF DIRECTORS

78. Subject to the provisions of the Act, the memorandum and the articles and to
any directions given by special resolution the business of the Company shall be
managed by the Directors who may exercise all the powers of the Company. No
alteration of the memorandum or articles and no such direction shall invalidate
any prior act of the Directors which would have been valid if that alteration
had not been made or that direction had not been given. The powers given by this
regulation shall not be limited by any special power given to the Directors by
the articles and a meeting of Directors at which a quorum is present may
exercise all powers exercisable by the Directors.

                                                                              28


79. Without prejudice to the generality of the foregoing article the Directors
may from time to time at their discretion, raise or borrow, without the consent
of the members in General Meeting, such sum or sums of money for the purposes of
the Company's business as they may think fit and may secure the repayment of or
raise any such sum or sums as aforesaid in such manner and upon such terms and
conditions and in all other respects as they may think fit, and in particular by
mortgages, deeds of bond and security, or other charges upon the whole or any
part of the property and assets of the Company, present or future, including its
uncalled or unissued capital, or by the issue at such price as they may think
fit, of bonds or debentures or debenture stock of the Company, either charged
upon the whole or any part of the property and assets of the Company, or not so
charged, or in any other way that the Directors may think expedient, and the
Directors may issue debentures or debenture stock or paid-up shares to any
person or persons as consideration for the purchase of any goodwill, business or
property purchased by the Company.

80. The Directors may, by power of attorney or otherwise, appoint any person to
be the agent of the Company for such purposes and on such conditions as they
determine, including authority for the agent to delegate all or any of his
powers. The Company may exercise the powers conferred by Sections 32 and 104 of
the Companies Act, 1931 and those powers shall accordingly be exercisable by the
Directors.


                         DELEGATION OF DIRECTORS' POWERS

81. The Directors may delegate any of their powers to any committee consisting
of one or more Directors. They may also delegate to any Managing Director or any
Director holding any other executive office such of their powers as they
consider desirable to be exercised by him. Any such delegation may be made
subject to any conditions the Directors may impose and either collaterally with
or to the exclusion of their own powers and may be revoked or altered. Subject
to any such conditions, the

82. The Company may from time to time in general meeting increase or reduce the
number of Directors. The Company may by special resolution remove any Director
or by ordinary resolution appoint any person to be a Director.

83. No person other than a first Director shall be appointed a Director in
general meeting unless at least seven days' and not more than fourteen days'
notice shall have been left at the registered office of the Company of the
intention to propose him, together with a notice in writing by the person to be
proposed of his willingness to be appointed.

84. The Directors shall have power at any time, and from time to time, to fill
any casual vacancy occurring in the Board of Directors or to appoint a person as
an additional Director.

85. A Director may hold any other office or place or profit under the Company,
except that of Auditor, upon such terms as to remuneration, tenure of office and
otherwise as may be determined by the Board.

the Company in general meeting and unless otherwise directed any such

agreement, equally. The Directors shall also be entitled to be repaid all
travelling and hotel expenses reasonably incurred by them respectively in or
about the performance of their duties as Directors.

                           the appointment of a receiver, curator bonis or other

                      DIRECTORS' APPOINTMENTS AND INTERESTS

89. Subject to the provisions of the Act, the Directors may appoint one or more
of their number to the office of Managing Director or to any other executive
office under the Company and may enter into an agreement or arrangement with any
Director for his employment by the Company or for the provision by him of any
services outside the scope of the ordinary duties of a Director. Any such
appointment, agreement or arrangement may be made upon such terms as the
Directors determine and they may remunerate any such Director for his services
as they think fit. Any appointment of a Director to an executive office shall
terminate if he ceases to be a Director but without prejudice to any claim to
damages for breach of the contract of service between the Director and the
Company.

90. Subject to the provisions of the Act and provided that he has disclosed to
the Directors the nature and extent of any material interest of his, a Director
notwithstanding his office -


                  (a) may be a party to, or otherwise interested in, any
                  transaction or arrangement with the Company or in which the
                  Company is otherwise interested;

                  (b) may be a Director or other officer of, or employed by, or
                  a party to any transaction or arrangement with, or otherwise
                  interested in, any body corporate promoted by the Company or
                  in which the Company is otherwise interested; and

                  (c) shall not, by reason of his office, be accountable to the
                  Company for any benefit which he derives from any such office
                  or employment or


<PAGE>

                                                                              32


                  from any such transaction or arrangement or from any interest
                  in any such body corporate and no such transaction or
                  arrangement shall be liable to be avoided on the ground of any
                  such interest or benefit.

91. For the purposes of the foregoing article -

                  (a) a general notice given to the Directors that a Director is
                  to be regarded as having an interest of the nature and extent
                  specified in the notice in any transaction or arrangement in
                  which a specified person or class of persons is interested
                  shall be deemed to be a disclosure that the Director has an
                  interest in any such transaction of the nature and extent so
                  specified; and

                  (b) an interest of which a Director has no knowledge and of
                  which it is unreasonable to expect him to have knowledge shall
                  not be treated as an interest of his.

92. Subject to article 90 hereof and the Act if the Company is a single member
company and having one member it enters into a contract with the sole member
otherwise than in the ordinary course of the Company's business and the sole
member is also a director of the Company, the Company should, unless the
contract is in writing, ensure that the terms of the contract are either set out
in a written memorandum or are recorded in the minutes of the first meeting of
the directors of the Company following the making of the contract.


                       DIRECTORS' GRATUITIES AND PENSIONS

93. Subject to the provisions of the Act, the Directors may provide benefits,

who has held but no longer holds any executive office or employment with the
Company or with any body corporate which is or has been a subsidiary of the
Company or a predecessor of the Company or of any such subsidiary and for any
member of his family (including a spouse and a former spouse) or any person who
is or was dependent on him, and may (as well before as after he ceases to hold
such office or employment) contribute to any fund and pay premiums for the
purchase or provision of any such benefit.


                            PROCEEDINGS OF DIRECTORS

94. Subject to the provisions of the articles, the Directors may regulate their
proceedings as they think fit. A Director may, and the secretary at the request
of a Director shall, call a meeting of the Directors. Questions arising at a
meeting shall be decided by a majority of votes. In the case of an equality of
votes, the Chairman shall have a second or casting vote. A Director who is also
an alternate Director shall be entitled in the absence of his appointor to a
separate vote on behalf of his appointor in addition to his own vote.

95. The quorum for the transaction of the business of the Directors may be fixed
by the Directors and unless so fixed at any other number shall be two. A person
who holds office only as an alternate Director shall, if his appointor is not
present, be counted in the quorum.

96. The continuing Directors or a sole continuing Director may act
notwithstanding any vacancies in their number, but, if the number of Directors
is less than the number fixed as the quorum, the continuing Directors or
Director may act only for the purpose of filling vacancies or of calling a
general meeting.


<PAGE>

                                                                              34


97. The Directors may appoint one of their number to be the Chairman of the
Board of Directors and may at any time remove him from that office. Unless he is
unwilling to do so, the Director so appointed shall preside at every meeting of
Directors at which he is present. But if there is no Director holding that
office, or if the Director holding it is unwilling to preside or is not present
within five minutes after the time appointed for the meeting, the Directors
present may appoint one of their number to be Chairman of the meeting.

98. All acts done by a meeting of Directors, or of a committee of Directors, or
by a person acting as a Director shall, notwithstanding that it be afterwards
discovered that there was a defect in the appointment of any Director or that
any of them were disqualified from holding office, or had vacated office, or
were not entitled to vote, be valid as if every such person had been duly
appointed and was qualified and had continued to be a Director and had been
entitled to vote.

99. A resolution in writing signed by all the Directors entitled to receive
notice of a meeting of Directors or of a committee of Directors shall be as
valid and effectual as if it had been passed at a meeting of Directors or (as
the case may be) a committee of Directors duly convened and held and may consist
of several documents in the like form each signed by one or more Directors, but
a resolution signed by an alternate need not also be signed by his appointor
and, if it is signed by a Director who has appointed an alternate Director, it
need not be signed by the alternate Director in that capacity.

100. Save as otherwise provided by the articles, a Director shall not vote at a
meeting of Directors or of a committee of Directors on any resolution concerning
a matter in which he has, directly or indirectly, an interest or duty which is
material and which conflicts or may conflict with the interest of the Company
unless he has declared the nature of his interest in the manner required by
Section 148 of the Act.

                                                                              35


101. A Director shall not be counted in the quorum present at a meeting in
relation to a resolution on which he is not entitled to vote.

102. The Company may by ordinary resolution suspend or relax to any extent,
either generally or in respect of any particular matter, any provision of the
articles prohibiting a Director from voting at a meeting of Directors or of a
committee of Directors.

103. If a question arises at a meeting of Directors or of a committee of
Directors as to the right of a Director to vote, the question may, before the
conclusion of the meeting, be referred to the Chairman of the meeting and his
ruling in relation to any Director other than himself shall be final and
conclusive.

104. Any Director or member of a committee of the Directors may participate in a
meeting of the Directors or such committee by means of telephonic or similar
communications whereby all persons participating in the meeting can hear each
other and participation in a meeting in this manner shall be deemed to
constitute presence in person at such meeting. The location of such a telephonic
meeting shall be deemed to be the place at which the Chairman of the meeting was
located at the time of the meeting.




                             MANAGEMENT AND CONTROL

105. The management and control of the business of the Company shall be in and

decide.


<PAGE>

                                                                              36


                                    SECRETARY

106. Subject to the provisions of the Act, the secretary shall be appointed by
the Directors for such term, at such remuneration and upon such conditions as
they may think fit; and any secretary so appointed may be removed by them.



                                     MINUTES

107. The Directors shall cause Minutes to be made in books kept for the purpose
- -

                  (a) of all appointments of officers made by the Directors; and

                  (b) of all proceedings at meetings of the Company, of the
                  holders of any class of shares in the Company and of the
                  Directors, and of committees of Directors, including the names
                  of the Directors present at such meeting.


                                    THE SEAL

108. The Company shall have a Company Seal.

109. The seal shall only be used by the authority of the Directors or of a
committee of Directors authorised by the Directors. The Directors may determine
who shall sign any instrument to which the seal is affixed and unless otherwise
so determined it shall be signed by a Director and by the secretary or by a
second Director.

                                                                              37


                                    DIVIDENDS

110. Subject to the provisions of the Act, the Company may by ordinary
resolution declare dividends in accordance with the respective rights of the
members, but no dividend shall exceed the amount recommended by the Directors.

111. Subject to the provisions of the Act, the Directors may pay interim
dividends if it appears to them that they are justified by the profits of the
Company available for distribution. If the share capital is divided into
different classes, the Directors may pay interim dividends on shares which
confer deferred or non-preferred rights with regard to dividend as well as on
shares which confer preferential rights with regard to dividend, but no interim
dividend shall be paid on shares carrying deferred or non-preferential rights
if, at the time of payment, any preferential dividend is in arrear. The
Directors may also pay at intervals settled by them any dividend payable at a
fixed rate if it appears to them that the profits available for distribution
justify the payment. Provided the Directors act in good faith they shall not
incur any liability to the holders of shares conferring preferred rights for any
loss they may suffer by the lawful payment of an interim dividend on any shares
having deferred or non-preferred rights.

112. Except as otherwise provided by the rights attached to shares, all
dividends shall be declared and paid according to the amounts paid up on the
shares on which the dividend is paid. All dividends shall be apportioned and
paid proportionately to the amounts paid up on the shares during any portion or
portions of the period in respect of which the dividend is paid; but, if any
share is issued on terms providing that it shall rank for dividend as from a
particular date, that share shall rank for dividend accordingly.

113. A general meeting declaring a dividend may, upon the recommendation of the
Directors, direct that it shall be satisfied wholly or partly by the
distribution of assets


<PAGE>

                                                                              38


and where any difficulty arises in regard to the distribution, the Directors may
settle the same and in particular may issue fractional certificates and fix the
value for distribution of any assets and may determine that cash shall be paid
to any member upon the footing of the value so fixed in order to adjust the
rights of members and may vest any assets in trustees.

114. Any dividend or other moneys payable in respect of a share may be paid by
cheque sent by post to the registered address of the person entitled or, if two
or more persons are the holders of the share or are jointly entitled to it by
reason of the death or bankruptcy of the holder, to the registered address of
that one of those persons who is first named in the register of members or to
such person and to such address as the person or persons entitled may in writing
direct. Every cheque shall be made payable to the order of the person or persons
entitled or to such other person as the person or persons entitled may in
writing direct and payment of the cheque shall be a good discharge to the
Company. Any joint holder or other person jointly entitled to a share as
aforesaid may give receipts for any dividend or other moneys payable in respect
of the share.

115. No dividend or other moneys payable in respect of a share shall bear
interest against the Company unless otherwise provided by the rights attached to
the share.

116. Any dividend which has remained unclaimed for twelve years from the date
when it became due for payment shall, if the Directors so resolve, be forfeited
and cease to remain owing by the Company.


                                    ACCOUNTS

117.              (a) No member shall (as such) have any right of inspecting any
                  accounting records or other book or document of the Company
                  except as


<PAGE>

                                                                              39


                  conferred by statute or authorised by the Directors or by
                  ordinary resolution of the Company.

                  (b) The Company shall prepare such accounts as may be required
                  by the Act and the laws of the Isle of Man.

                  (c) Subject to the Act and the laws of the Isle of Man the
                  Company may elect to dispense with compliance with the
                  requirements of the Act which relate to the audit of the
                  accounts of the Company.


                            CAPITALISATION OF PROFITS

118. The Directors may with the authority of an ordinary resolution of the
Company -

                  (a) subject as hereinafter provided, resolve to capitalise any
                  undivided profits of the Company not required for paying any
                  preferential dividend (whether or not they are available for
                  distribution) or any sum standing to the credit of the
                  Company's share premium account or capital redemption reserve;

                  (b) appropriate the sum resolved to be capitalised to the
                  members who would have been entitled to it if it were
                  distributed by way of dividend and in the same proportions and
                  apply such sum on their behalf either in or towards paying up
                  the amounts, if any, for the time being unpaid on any shares
                  held by them respectively, or in paying up in full unissued
                  shares or debentures of the Company of a nominal amount, equal
                  to that sum, and allot the shares or debentures credited as
                  fully paid to those members, or as they may direct, in those
                  proportions, or partly in one way and partly in the other: but
                  the share premium account, the capital


<PAGE>

                                                                              40


                  redemption reserve and any profits which are not available for
                  distribution may, for the purposes of this regulation, only be
                  applied in paying up unissued shares to be allotted to members
                  credited as fully paid;

                  (c) make such provision by the issue of fractional
                  certificates or by payment in cash or otherwise as they
                  determine in the case of shares or debentures becoming
                  distributable under this regulation in fractions; and

                  (d) authorise any person to enter on behalf of all the members
                  concerned into an agreement with the Company providing for the
                  allotment to them respectively, credited as fully paid, of any
                  shares or debentures to which they are entitled upon such
                  capitalisation, any agreement made under such authority being
                  binding on all such members.


                                     NOTICES

119. Any notice to be given to or by any person pursuant to the articles shall
be in writing except that a notice calling a meeting of the Directors need not
be in writing.

120. The Company may give any notice to a member either personally or by sending
it by post in a prepaid envelope addressed to the member at his registered
address or by leaving it at that address. In the case of joint holders of a
share, all notices shall be given to the joint holder whose name stands first in
the register of members in respect of the joint holding and notice so given
shall be sufficient notice to all the joint holders. A member whose registered
address is not within the British Islands and who gives to the Company an
address within the British Islands at which notices may be given to him shall be
entitled to have notices given to him at that address, but otherwise no such
member shall be entitled to receive any notice from the Company.


<PAGE>

                                                                              41


121. A member present, either in person or by proxy, at any meeting of the
Company or of the holders of any class of shares in the Company shall be deemed
to have received notice of the meeting and, where requisite, of the purposes for
which it was called.

122. Every person who becomes entitled to a share shall be bound by any notice
in respect of that share which, before his name is entered in the register of
members, has been duly given to a person from whom he derives his title.

123. Proof that an envelope containing a notice was properly addressed, prepaid
and posted shall be conclusive evidence that the notice was given. A notice
shall be deemed to be given at the expiration of 48 hours after the envelope
containing it was posted.

124. A notice may be given by the Company to the persons entitled to a share in
consequence of the death or bankruptcy of a member by sending or delivering it,
in any manner authorised by the articles for the giving of notice to a member,
addressed to them by name, or by the title of representatives of the deceased,
or trustee of the bankrupt or by any like description at the address, if any,
within the British Islands supplied for that purpose by the persons claiming to
be so entitled. Until such an address has been supplied, a notice may be given
in any manner in which it might have been given if the death or bankruptcy had
not occurred.


                                   WINDING UP

125. If the Company is wound up, the liquidator may, with the sanction of an
extraordinary resolution of the Company and any other sanction required by the
Act, divide among the members in specie the whole or any part of the assets of
the Company and may, for that purpose, value any assets and determine how the
division


<PAGE>

                                                                              42


shall be carried out as between the members or different classes of members. The
liquidator may, with the like sanction, vest the whole or any part of the assets
in trustees upon such trusts for the benefit of the members as he with the like
sanction determines, but no member shall be compelled to accept any assets upon
which there is a liability.


                                    INDEMNITY

126. Every Director or other officer of the Company shall be entitled to be
indemnified out of the assets of the Company against all losses or liabilities
(including any such liability as is mentioned in paragraph (c) of the proviso to
Section 151 of the Act) which he may sustain or incur in or about the execution
of the duties of his office or otherwise in relation thereto, and no Director or
other officer shall be liable for any loss, damage or misfortune which may
happen to or be incurred by the Company in the execution of the duties of his
office or in relation thereto. But this Article shall only have effect in so far
as its provisions are not avoided by the said Section.

127. The Company may purchase and maintain indemnity insurance for the benefit
of each Director or other officer of the Company.

<PAGE>

                                                                               7


(3) In these regulations, unless there is something in the subject of context
inconsistent with such construction:-

                  (a) words importing the plural number shall be deemed to
                  include the singular number and words importing the singular
                  number shall be deemed to include the plural number;

                  (b) words importing the masculine gender only include the
                  feminine gender;

                  (c) words importing persons include companies or associations
                  or bodies of persons whether corporate or unincorporate.

4. Statutory references used in these articles shall be read to include any

substitution therefor.


                                  SHARE CAPITAL

5.       (1) Subject to the provisions of the Act and without prejudice to any
         rights attached to any existing shares, any share may be issued with
         such rights or restrictions as the Company may by ordinary resolution
         determine.

         (2) Subject to the provisions of the Act, shares may be issued in
         fractional denominations to the same extent as whole shares.

6. Subject to the provisions of the Act and the articles, redeemable preference
shares may be issued on such terms and in such manner as may be provided by the
articles.


<PAGE>

                                                                               8


7. The Company may exercise the powers of paying commissions conferred by the
Act. Subject to the provisions of the Act, any such commissions may be satisfied
by the payment of cash or by the allotment of fully or partly paid shares or
partly in one way and partly in the other.

8. Except as required by law, no person shall be recognised by the Company as
holding any share upon any trust and (except as otherwise provided by the
articles or by law) the Company shall not be bound by or recognise any interest
in any share except an absolute right to the entirety thereof in the holder.

9. The shares shall be at the disposal of the Directors, and (save as otherwise
directed by the Company in General Meeting) they may allot or otherwise dispose
of them to such persons at such times and generally on such terms and conditions
as they think proper, subject nevertheless to article 2 and provided that no
shares shall be issued at a discount, except as provided by Section 47 of the
Act.

10. If at any time the share capital is divided into different classes of
shares, the rights attached to any class (unless otherwise provided by the terms
of issue of the shares of that class) may be varied with the consent in writing
of the holders of all of the issued shares of that class, or with the sanction
of an extraordinary resolution passed at a separate general meeting of the
holders of the shares of the class. To every such separate general meeting the
provisions of these regulations relating to general meetings shall in the case
of the number of holders of a particular class of shares being two or more
mutatis mutandis apply, but so that the necessary quorum shall be two persons at
least holding or representing by proxy one-third of the issued shares of the
class, and that any holder of shares of the class present in person or by proxy
may demand a poll. In the case of the number of holders of a particular class of
shares being one, one person holding or representing all the issued shares of
the class shall be a quorum.


<PAGE>

                                                                               9


11. The Company may issue share warrants to bearer in respect of any fully
paid-up shares of the Company, stating that the bearer of the warrant is
entitled to the shares therein specified. Such warrants shall be issued upon
such terms and subject to such conditions as may be resolved upon by the
Directors. Subject to the provisions of the Act and of these articles the holder
of a share warrant shall be deemed to be a member of the Company and shall be
entitled to the same rights and privileges as he would have had if his name had
been included in the share register of the Company as the holder of the shares.


                               SHARE CERTIFICATES

12.      (1) Every member, upon becoming the holder of any shares shall be
         entitled

                  (a) without payment, to one certificate for all the shares of
                  each class held by him (and, upon transferring a part of his
                  holding of shares of any class, to a certificate for the
                  balance of such holding); or

                  (b) to several certificates each for one or more of his shares
                  upon payment, for every certificate after the first, of such
                  reasonable sum as the Directors may determine.

         (2) Every certificate shall be sealed with the seal and shall specify
         the number, class and distinguishing numbers (if any) of the shares to
         which it relates and the amount or respective amounts paid up thereon.

         (3) The Company shall not be bound to issue more than one certificate
         for shares held jointly by several persons and delivery of a
         certificate to one joint holder shall be a sufficient delivery to all
         of them.


<PAGE>

                                                                              10


13. If a share certificate is defaced, worn-out, lost or destroyed, it may be
renewed on such terms (if any) as to evidence and indemnity and payment of the
expenses reasonably incurred by the Company in investigating evidence as the
Directors may determine but otherwise free of charge, and (in the case of
defacement or wearing-out) on delivery up of the old certificate.

14. The Company shall have a first and paramount lien on every share for all
moneys (whether presently payable or not) payable at a fixed time or called in
respect of that share. The Directors may at any time declare any share to be
wholly or in part exempt from the provisions of this regulation. The Company's
lien on a share shall extend to any amount payable in respect of it.

15. The Company may sell in such manner as the Directors determine any shares on
which the Company has a lien if a sum in respect of which the lien exists is
presently payable and is not paid within fourteen clear days after notice has
been given to the holder of the share or to the person entitled to it in
consequence of the death or bankruptcy of the holder, demanding payment and
stating that if the notice is not complied with the shares may be sold.

16. To give effect to a sale the Directors may authorise some person to execute
an instrument of transfer of the shares, sold to, or in accordance with the
directions of, the purchaser. The title of the transferee to the shares shall
not be affected by any irregularity in or invalidity of the proceedings in
reference to the sale.

17. The net proceeds of the sale, after payment of the costs, shall be applied
in payment of so much of the sum for which the lien exists as is presently
payable, and any residue shall (upon surrender to the Company for cancellation
of the certificate for the shares sold and subject to a like lien for any moneys
not presently payable as existed upon the shares before the sale) be paid to the
person entitled to the shares at the date of the sale.

                                                                              11


                         CALLS ON SHARES AND FORFEITURE

18. Subject to the terms of allotment, the Directors may make calls upon the
members in respect of any moneys unpaid on their shares (whether in respect of
nominal value or premium) and each member shall (subject to receiving at least
fourteen clear days notice specifying when and where payment is to be made) pay
to the Company as required by the notice the amount called on his shares. A call
may be required to be paid by instalments. A call may, before receipt by the
Company of any sum due thereunder, be revoked in whole or in part and payment of
a call may be postponed in whole or in part. A person upon whom a call is made
shall remain liable for calls made upon him notwithstanding the subsequent
transfer of the shares in respect whereof the call was made.

19. A call shall be deemed to have been made at the time when the resolution of
the Directors authorising the call was passed.

20. The joint holders of a share shall be jointly and severally liable to pay
all calls in respect thereof.

21. If a call remains unpaid after it has become due and payable the person from
whom it is due and payable shall pay interest on the amount unpaid from the day
it became due and payable until it is paid at the rate fixed by the terms of
allotment of the share or in the notice of the call or, if no rate is fixed, at
the rate of (pound)5 per centum per annum but the Directors may waive payment of
the interest wholly or in part.

22. An amount payable in respect of a share on allotment or at any fixed date,
whether in respect of nominal value or premium or as an instalment of a call,
shall be deemed to be a call and if it is not paid the provisions of the
articles shall apply as if that amount had become due and payable by virtue of a
call.


<PAGE>

                                                                              12


23. Subject to the terms of allotment, the Directors may make arrangements on
the issue of shares for a difference between the holders in the amounts and
times of payment of calls on their shares.

24. If a call remains unpaid after it has become due and payable the Directors
may give to the person from whom it is due not less than fourteen clear days'
notice requiring payment of the amount unpaid together with any interest which
may have accrued. The notice shall name the place where payment is to be made
and shall state that if the notice is not complied with the shares in respect of
which the call was made will be liable to be forfeited.

25. If the notice is not complied with any share in respect of which it was
given may, before the payment required by the notice has been made, be forfeited
by a resolution of the Directors and the forfeiture shall include all dividends
or other moneys payable in respect of the forfeited shares and not paid before
the forfeiture.

26. Subject to the provisions of the Act, a forfeited share may be sold,
re-allotted or otherwise disposed of on such terms and in such manner as the
Directors determine either to the person who was before the forfeiture the
holder or to any other person and at any time before sale, re-allotment or other
disposition, the forfeiture may be cancelled on such terms as the Directors
think fit. Where for the purposes of its disposal a forfeited share is to be
transferred to any person the Directors may authorise some person to execute an
instrument of transfer of the share to that person.

27. A person any of whose shares have been forfeited shall cease to be a member
in respect of them and shall surrender to the Company for cancellation the
certificate for the shares forfeited but shall remain liable to the Company for
all moneys which at the date of forfeiture were presently payable by him to the
Company in respect of those shares with interest at the rate at which interest
was payable on those moneys before the forfeiture or, if no interest was so
payable, at the rate of (pound)5 per centum per annum


<PAGE>

                                                                              13


from the date of forfeiture until payment but the Directors may waive payment
wholly or in part or enforce payment without any allowance for the value of the
shares at the time of forfeiture or for any consideration received on their
disposal.

28. A statutory declaration by a Director or the secretary that a share has been
forfeited on a specified date shall be conclusive evidence of the facts stated
in it as against all persons claiming to be entitled to the share and the
declaration shall (subject to the execution of an instrument of transfer if
necessary) constitute a good title to the share and the person to whom the share
is disposed of shall not be bound to see to the application of the
consideration, if any, nor shall his title to the share be affected by any
irregularity in or invalidity of the proceedings in reference to the forfeiture
or disposal of the share.


                               TRANSFER OF SHARES

29. The instrument of transfer of a share may be in any usual form or in any
other form which the Directors may approve and shall be executed by or on behalf
of the transferor and, unless the share is fully paid, by or on behalf of the
transferee.

30. No transfer of any share in the capital of the Company to any person not
already a member of the Company shall be made or registered without the previous
sanction of the Directors, who may without assigning any reason, decline to give
any such sanction. The Directors may also suspend the registration of transfers
during the fourteen days immediately preceding the Ordinary General Meeting in
each year. The Directors may decline to recognise any instrument of transfer
unless accompanied by the certificate of the shares to which it relates, and
such other evidence as the Directors may reasonably require to show the right of
the transferor to make the transfer. The Directors may decline to register a
transfer of any shares on which the Company has a lien. If the Directors refuse
to register a transfer of any share they


<PAGE>

                                                                              14


shall within two months after the date on which the transfer was lodged with the
Company send to the transferee notice of the refusal as required by section 67
of the Act.

31. The Company shall be entitled to retain any instrument of transfer which is
registered, but any instrument of transfer which the Directors refuse to
register shall be returned to the person lodging it when notice of the refusal
is given.


                             TRANSMISSION OF SHARES

32. If a member dies the survivor or survivors where he was a joint holder, and
his personal representatives where he was a sole holder or the only survivor of
joint holders, shall be the only persons recognised by the Company as having any
title to his interest; but nothing herein contained shall release the estate of
a deceased member from any liability in respect of any share which had been
jointly held by him.

33. A person becoming entitled to a share in consequence of the death or
bankruptcy of a member may, upon such evidence being produced as the Directors
may properly require, elect either to become the holder of the share or to have
some person nominated by him registered as the transferee. If he elects to
become the holder he shall give notice to the Company to that effect. If he
elects to have another person registered he shall execute an instrument of
transfer of the share to that person. All articles relating to the transfer of
shares shall apply to the notice or instrument of transfer as if it were an
instrument of transfer executed by the member and the death or bankruptcy of the
member had not occurred.

34. A person becoming entitled to a share in consequence of the death or
bankruptcy of a member shall have the rights to which he would be entitled if he
were the holder of the share, except that he shall not, before being registered
as the holder


<PAGE>

                                                                              15


of the share, be entitled in respect of it to attend or vote at any meeting of
the Company or at any separate meeting of the holders of any class of shares in
the Company.


                           ALTERATION OF SHARE CAPITAL

35. The Company may by ordinary resolution -

                  (a) increase its share capital by new shares of such amount as
                  the resolution prescribes;

                  (b) consolidate and divide all or any or its share capital
                  into shares of larger amount than its existing shares;

                  (c) subject to the provisions of the Act, sub-divide its
                  shares, or any of them, into shares of smaller amount and the
                  resolution may determine that, as between the shares resulting
                  from the sub-division, any of them may have any preference or
                  advantage as compared with the others; and

                  (d) cancel shares which, at the date of the passing of the
                  resolution, have not been taken or agreed to be taken by any
                  person and diminish the amount of its share capital by the
                  amount of the shares so cancelled.

36. Whenever as a result of a consolidation of shares any members would become
entitled to fractions of a share, the Directors may, instead of issuing the
fractions of a share, on behalf of those members, sell the shares representing
the fractions for the best price reasonably obtainable to any person (including,
subject to the provisions of the Act, the Company) and distribute the net
proceeds of sale in due proportion among those members, and the Directors may
authorise some person to execute an instrument of transfer of the shares to, or
in accordance with the directions of, the purchaser. The


<PAGE>

                                                                              16


transferee shall not be bound to see to the application of the purchase money
nor shall his title to the shares be affected by any irregularity in or
invalidity of the proceedings in reference to the sale.

37. Subject to the provisions of the Act, the Company may by special resolution
reduce its share capital, any capital redemption reserve and any share premium
account in any way.


                         CONVERSION OF SHARES INTO STOCK

38. The Company may by ordinary resolution convert any paid-up shares into stock
and reconvert any stock into paid-up shares of any denomination.

39. The holders of stock may transfer the same, or any part thereof, in the same
manner, and subject to the same regulations, as, and subject to which, the
shares from which the stock arose might previously to conversion have been
transferred, or as near thereto as circumstances admit; but the Directors may
from time to time fix the minimum amount of stock transferable and restrict or
forbid the transfer of fractions of that minimum, but the minimum shall not
exceed the nominal amount of the shares from which the stock arose.

40. The holders of stock shall, according to the amount of the stock held by
them, have the same rights, privileges and advantages as regards dividends,
voting at meetings of the Company and other matters as if they held the shares
from which the stock arose, but no such privilege or advantage (except
participation in the dividends and profits of the Company) shall be conferred by
any such aliquot part of stock as would not, if existing in shares, have
conferred that privilege or advantage.


<PAGE>

                                                                              17


41. Such of the regulations of the Company as are applicable to paid-up shares
shall apply to stock and the words "shares" and "shareholder" therein shall
include "stock" and "stockholder".


                         REDEMPTION OF PREFERENCE SHARES

42. Subject to the provisions of the Act, the redemption of redeemable
preference shares shall be effected on such terms and in such manner, as may be
provided by the articles.


                                GENERAL MEETINGS

43. All general meetings other than annual general meetings shall be called
extraordinary general meetings.

44. The Directors may call general meetings, and on the requisition of a member
pursuant to the provisions of the Act, shall forthwith proceed to convene an
extraordinary general meeting for a date not later than eight weeks after
receipt of the requisition. If there are not within the Isle of Man sufficient
Directors to call a general meeting, any Director or any member of the Company
may call a general meeting.


                           NOTICE OF GENERAL MEETINGS

45. An annual general meeting and an extraordinary general meeting called for
the passing of a special resolution or a resolution appointing a person as a
Director shall be called by at least twenty-one clear days' notice. All other
extraordinary general


<PAGE>

                                                                              18


meetings shall be called by at least fourteen clear days' notice but a general
meeting may be called by shorter notice if it is so agreed -

                  (a) In the case of an annual general meeting, by all the
                  members entitled to attend and vote thereat; and

                  (b) In the case of any other meeting by a majority in number
                  of the members having a right to attend and vote being a
                  majority together holding not less than ninety five per cent
                  in nominal value of the shares giving that right.

The notice shall specify the time and place of the meeting and the general
nature of the business to be transacted and, in the case of an annual general
meeting, shall specify the meeting as such.

Subject to the provisions of the articles and to any restrictions imposed on any
shares, the notice shall be given to all the members, to all persons entitled to
a share in consequence of the death or bankruptcy of a member and to the
Directors and auditors.

46. The accidental omission to give notice of a meeting to or the non-receipt of
notice of a meeting by any person entitled to receive notice shall not
invalidate the proceedings at that meeting.


                         PROCEEDINGS AT GENERAL MEETINGS

47. No business shall be transacted at any meeting unless a quorum is present.
Two persons entitled to vote upon the business to be transacted, each being a
member or a proxy for a member or a duly authorised representative of a
corporation which is a member, shall be a quorum. When the Company has a single
member, the member


<PAGE>

                                                                              19


or the proxy for the member or a duly authorised representative of the
corporation which is the member, shall be a quorum.

48. If such a quorum is not present within half an hour from the time appointed
for the meeting or if during a meeting such a quorum ceases to be present, the
meeting shall stand adjourned to the same day in the next week at the same time
and place or to such time and place as the Directors may determine.

49. The Chairman, if any, of the Board of Directors or in his absence some other
Director nominated by the Directors shall preside as Chairman of the meeting,
but if neither the Chairman nor such other Director (if any) be present within
fifteen minutes after the time appointed for holding the meeting and willing to
act, the Directors present shall elect one of their number to be Chairman and if
there is only one Director present and willing to act, he shall be Chairman.

50. If no Director is willing to act as Chairman, or if no Director is present
within fifteen minutes after the time appointed for holding the meeting, the
members present and entitled to vote shall choose one of their number to be
Chairman.

51. A Director shall, notwithstanding that he is not a member, be entitled to
attend and speak at any general meeting and at any separate meeting of the
holders of any class of shares in the Company.

52. The Chairman may, with the consent of a meeting at which a quorum is present
(and shall if so directed by the meeting), adjourn the meeting from time to time
and from place to place, but no business shall be transacted at an adjourned
meeting other than business which might properly have been transacted at the
meeting had the adjournment not taken place. When a meeting is adjourned for
fourteen days or more, at least seven clear days' notice shall be given
specifying the time and place of the


<PAGE>

                                                                              20


adjourned meeting and the general nature of the business to be transacted.
Otherwise it shall not be necessary to give any such notice.

53. A resolution put to the vote of a meeting shall be decided on a show of
hands unless before, or on the declaration of the result of, the show of hands a
poll is duly demanded. Subject to the provisions of the Act, a poll may be
demanded -

         (a) by the Chairman; or

                  (b) by at least two members having the right to vote at the
                  meeting; or

                  (c) by a member or members representing no less than one-tenth
                  of the total voting rights of all the members having the right
                  to vote at the meeting; or

                  (d) by a member or members holding shares conferring a right
                  to vote at the meeting being shares on which an aggregate sum
                  has been paid up equal to not less than one-tenth of the total
                  sum paid up on all the shares conferring that right;

and a demand by a person as proxy for a member shall be the same as a demand by
the member.

54. Unless a poll is duly demanded a declaration by the Chairman that a
resolution has been carried or carried unanimously, or by a particular majority,
or lost, or not carried by a particular majority and an entry to that effect in
the minutes of the meeting shall be conclusive evidence of the fact without
proof of the number or proportion of the votes recorded in favour of or against
the resolution.


<PAGE>

                                                                              21


55. The demand for a poll may, before the poll is taken, be withdrawn but only
with the consent of the Chairman and a demand so withdrawn shall not be taken to
have invalidated the result of a show of hands declared before the demand was
made.

56. A poll shall be taken as the Chairman directs and he may appoint scrutineers
(who need not be members) and fix a time and place for declaring the result of
the poll. The result of the poll shall be deemed to be the resolution of the
meeting at which the poll was demanded.

57. In the case of an equality of votes, whether on a show of hands or on a
poll, the Chairman shall be entitled to a casting vote in addition to any other
vote he may have.

58. A poll demanded on the election of a Chairman or on a question of
adjournment shall be taken forthwith. A poll demanded on any other question
shall be taken either forthwith or at such time and place as the Chairman
directs not being more than thirty days after the poll is demanded. The demand
for a poll shall not prevent the continuance of a meeting for the transaction of
any business other than the question on which the poll was demanded. If a poll
is demanded before the declaration of the result of a show of hands and the
demand is duly withdrawn, the meeting shall continue as if the demand had not
been made.

59. No notice need be given of a poll not taken forthwith if the time and place
at which it is to be taken are announced at the meeting at which it is demanded.
In any other case at least seven clear days notice shall be given specifying the
time and place at which the poll is to be taken.

60. A resolution in writing executed by or on behalf of each member who would
have been entitled to vote upon it if it had been proposed at a general meeting
at which he was present shall be as effectual as if it had been passed at a
general meeting duly convened and held and may consist of several instruments in
the like form each


<PAGE>

                                                                              22


executed by or on behalf of one or more members, provided the provisions of
Section 118B of the Act are complied with and that such resolution is received
by the Company at its registered office within seven days of the date of its
execution in terms hereof.





                                VOTES OF MEMBERS

61. Subject to any rights or restrictions attached to any shares, on a show of
hands every member who (being an individual) is present in person or by proxy or
(being a corporation) is present by a duly authorised representative, not being
himself a member, shall have one vote and on a poll every member entitled to
vote shall have one vote for every share of which he is the holder.

62. In the case of joint holders the vote of the senior who tenders a vote,
whether in person or by proxy, shall be accepted to the exclusion of the votes
of the other joint holders; and seniority shall be determined by the order in
which the names of the holders stand in the register of members.

63. A member in respect of whom an order has been made by any court having
jurisdiction (whether in the Isle of Man or elsewhere) in matters concerning
mental disorder may vote, whether on a show of hands or on a poll, by his
receiver, curator bonis or other person authorised in that behalf appointed by
that court, and any such receiver, curator bonis or other person may, on a poll,
vote by proxy. Evidence to the satisfaction of the Directors of the authority of
the person claiming to exercise the right to vote shall be deposited at the
office, or at such other place as is specified in accordance with the articles
for the deposit of instruments of proxy, not less than 48 hours before the time
appointed for holding the meeting or adjourned meeting at which


<PAGE>

                                                                              23


the right to vote is to be exercised and in default the right to vote shall not
be exercisable.

64. No member shall vote at any general meeting or at any separate meeting of
the holders of any class of shares in the Company, either in person or by proxy,
in respect of any share held by him unless all moneys presently payable by him
in respect of that share have been paid.

65. No objections shall be raised to the qualification of any voter except at
the meeting or adjourned meeting at which the vote objected to is tendered, and
every vote not disallowed at the meeting shall be valid. Any objection made in
due time shall be referred to the Chairman whose decision shall be final and
conclusive.

66. On a poll votes may be given either personally or by proxy. A member may
appoint more than one proxy to attend on the same occasion.

67. An instrument appointing a proxy shall be in writing, executed by or on
behalf of the appointor and shall be in the following form (or in a form as near
thereto as circumstances allow or in any other form which is usual or which the
Directors may approve) -

                                     Limited

69. The instrument appointing a proxy and any authority under which it is
executed or a copy of such authority certified notarially or in some other way
approved by the Directors may-

                  (a) be deposited at the office or at such other place within
                  the Isle of Man as is specified in the notice convening the
                  meeting or in any instrument of proxy sent out by the Company
                  in relation to the meeting not less than 48 hours before the
                  time for holding the meeting or adjourned meeting at which the
                  person named in the instrument proposes to vote; or

                  (c) where the poll is not taken forthwith but is taken not
                  more than 48 hours after it was demanded, be delivered at the
                  meeting at which the poll was demanded, to the Chairman or to
                  the Secretary or to any Director;

and an instrument of proxy which is not deposited or delivered in a manner so
permitted shall be invalid.

70. A vote given or poll demanded by proxy or by the duly authorised
representative of a corporation shall be valid notwithstanding the previous
determination of the authority of the person voting or demanding a poll unless
notice of the determination was received by the Company at the office or at such
other place at which the instrument of proxy was duly deposited before the
commencement of the meeting or adjourned meeting at which the vote is given or
the poll demanded or (in the case of


<PAGE>

                                                                              26


a poll taken otherwise than on the same day as the meeting or adjourned meeting)
the time appointed for taking the poll.

71. Where the Company is a single member company and the sole member takes any
decision which may be taken by the Company in general meeting and which has
effect as if agreed by the Company in general meeting he shall subject to
article 60 provide the Company with a written record of that decision by
forwarding such record to the Company at its registered office within seven days
of the date upon which the decision was taken.




                               NUMBER OF DIRECTORS

72. Unless otherwise determined by ordinary resolution, the number of Directors
(other than alternate Directors) shall not be subject to any maximum.


                               ALTERNATE DIRECTORS

73. Any Director (other than an alternate Director) may appoint any other
Director, or any other person approved by resolution of the Directors and
willing to act, to be an alternate Director and may remove from office an
alternate Director so appointed by him.

74. An alternate Director shall be entitled to receive notice of all meetings of
Directors and of all meetings of committees of Directors of which his appointor
is a member, to attend and vote at any such meeting at which the Director
appointing him is not personally present and generally to perform all the
functions of his appointor as

                                                                              27


a Director in his absence but shall not be entitled to receive any remuneration
from the Company for his services as an alternate Director.

75. An alternate Director shall cease to be an alternate Director if his
appointor ceases to be a Director; but, if a Director retires by rotation or
otherwise but is reappointed or deemed to have been reappointed at the meeting
at which he retires; any appointment of an alternate Director made by him which
was in force immediately prior to his retirement shall continue after his
reappointment.

76. Any appointment or removal of an alternate Director shall be by notice to
the Company signed by the Director making or revoking the appointment or in any
other manner approved by the Directors.

77. Save as otherwise provided in the articles, an alternate Director shall be
deemed for all purposes to be a Director and shall alone be responsible for his
own acts and defaults and he shall not be deemed to be the agent of the Director
appointing him.


                               POWERS OF DIRECTORS

78. Subject to the provisions of the Act, the memorandum and the articles and to
any directions given by special resolution the business of the Company shall be
managed by the Directors who may exercise all the powers of the Company. No
alteration of the memorandum or articles and no such direction shall invalidate
any prior act of the Directors which would have been valid if that alteration
had not been made or that direction had not been given. The powers given by this
regulation shall not be limited by any special power given to the Directors by
the articles and a meeting of Directors at which a quorum is present may
exercise all powers exercisable by the Directors.

                                                                              28


79. Without prejudice to the generality of the foregoing article the Directors
may from time to time at their discretion, raise or borrow, without the consent
of the members in General Meeting, such sum or sums of money for the purposes of
the Company's business as they may think fit and may secure the repayment of or
raise any such sum or sums as aforesaid in such manner and upon such terms and
conditions and in all other respects as they may think fit, and in particular by
mortgages, deeds of bond and security, or other charges upon the whole or any
part of the property and assets of the Company, present or future, including its
uncalled or unissued capital, or by the issue at such price as they may think
fit, of bonds or debentures or debenture stock of the Company, either charged
upon the whole or any part of the property and assets of the Company, or not so
charged, or in any other way that the Directors may think expedient, and the
Directors may issue debentures or debenture stock or paid-up shares to any
person or persons as consideration for the purchase of any goodwill, business or
property purchased by the Company.

80. The Directors may, by power of attorney or otherwise, appoint any person to
be the agent of the Company for such purposes and on such conditions as they
determine, including authority for the agent to delegate all or any of his
powers. The Company may exercise the powers conferred by Sections 32 and 104 of
the Companies Act, 1931 and those powers shall accordingly be exercisable by the
Directors.


                         DELEGATION OF DIRECTORS' POWERS

81. The Directors may delegate any of their powers to any committee consisting
of one or more Directors. They may also delegate to any Managing Director or any
Director holding any other executive office such of their powers as they
consider desirable to be exercised by him. Any such delegation may be made
subject to any conditions the Directors may impose and either collaterally with
or to the exclusion of their own powers and may be revoked or altered. Subject
to any such conditions, the

number of Directors. The Company may by special resolution remove any Director
or by ordinary resolution appoint any person to be a Director.

83. No person other than a first Director shall be appointed a Director in
general meeting unless at least seven days' and not more than fourteen days'

otherwise as may be determined by the Board.

agreement, equally. The Directors shall also be entitled to be repaid all
travelling and hotel expenses reasonably incurred by them respectively in or
about the performance of their duties as Directors.

                      DIRECTORS' APPOINTMENTS AND INTERESTS

89. Subject to the provisions of the Act, the Directors may appoint one or more
of their number to the office of Managing Director or to any other executive
office under the Company and may enter into an agreement or arrangement with any
Director for his employment by the Company or for the provision by him of any
services outside the scope of the ordinary duties of a Director. Any such
appointment, agreement or arrangement may be made upon such terms as the
Directors determine and they may remunerate any such Director for his services
as they think fit. Any appointment of a Director to an executive office shall
terminate if he ceases to be a Director but without prejudice to any claim to
damages for breach of the contract of service between the Director and the
Company.

90. Subject to the provisions of the Act and provided that he has disclosed to
the Directors the nature and extent of any material interest of his, a Director
notwithstanding his office -


                  (a) may be a party to, or otherwise interested in, any
                  transaction or arrangement with the Company or in which the
                  Company is otherwise interested;

                  (b) may be a Director or other officer of, or employed by, or
                  a party to any transaction or arrangement with, or otherwise
                  interested in, any body corporate promoted by the Company or
                  in which the Company is otherwise interested; and

                  (c) shall not, by reason of his office, be accountable to the
                  Company for any benefit which he derives from any such office
                  or employment or


<PAGE>

                                                                              32


                  from any such transaction or arrangement or from any interest
                  in any such body corporate and no such transaction or
                  arrangement shall be liable to be avoided on the ground of any
                  such interest or benefit.

91. For the purposes of the foregoing article -

                  (a) a general notice given to the Directors that a Director is
                  to be regarded as having an interest of the nature and extent
                  specified in the notice in any transaction or arrangement in
                  which a specified person or class of persons is interested
                  shall be deemed to be a disclosure that the Director has an
                  interest in any such transaction of the nature and extent so
                  specified; and

                  (b) an interest of which a Director has no knowledge and of
                  which it is unreasonable to expect him to have knowledge shall
                  not be treated as an interest of his.

92. Subject to article 90 hereof and the Act if the Company is a single member
company and having one member it enters into a contract with the sole member
otherwise than in the ordinary course of the Company's business and the sole
member is also a director of the Company, the Company should, unless the
contract is in writing, ensure that the terms of the contract are either set out
in a written memorandum or are recorded in the minutes of the first meeting of
the directors of the Company following the making of the contract.


                       DIRECTORS' GRATUITIES AND PENSIONS

93. Subject to the provisions of the Act, the Directors may provide benefits,

who has held but no longer holds any executive office or employment with the
Company or with any body corporate which is or has been a subsidiary of the
Company or a predecessor of the Company or of any such subsidiary and for any
member of his family (including a spouse and a former spouse) or any person who
is or was dependent on him, and may (as well before as after he ceases to hold
such office or employment) contribute to any fund and pay premiums for the
purchase or provision of any such benefit.


                            PROCEEDINGS OF DIRECTORS

94. Subject to the provisions of the articles, the Directors may regulate their
proceedings as they think fit. A Director may, and the secretary at the request
of a Director shall, call a meeting of the Directors. Questions arising at a
meeting shall be decided by a majority of votes. In the case of an equality of
votes, the Chairman shall have a second or casting vote. A Director who is also
an alternate Director shall be entitled in the absence of his appointor to a
separate vote on behalf of his appointor in addition to his own vote.

95. The quorum for the transaction of the business of the Directors may be fixed
by the Directors and unless so fixed at any other number shall be two. A person
who holds office only as an alternate Director shall, if his appointor is not
present, be counted in the quorum.

96. The continuing Directors or a sole continuing Director may act
notwithstanding any vacancies in their number, but, if the number of Directors
is less than the number fixed as the quorum, the continuing Directors or
Director may act only for the purpose of filling vacancies or of calling a
general meeting.


<PAGE>

                                                                              34


97. The Directors may appoint one of their number to be the Chairman of the
Board of Directors and may at any time remove him from that office. Unless he is
unwilling to do so, the Director so appointed shall preside at every meeting of
Directors at which he is present. But if there is no Director holding that
office, or if the Director holding it is unwilling to preside or is not present
within five minutes after the time appointed for the meeting, the Directors
present may appoint one of their number to be Chairman of the meeting.

98. All acts done by a meeting of Directors, or of a committee of Directors, or
by a person acting as a Director shall, notwithstanding that it be afterwards
discovered that there was a defect in the appointment of any Director or that
any of them were disqualified from holding office, or had vacated office, or
were not entitled to vote, be valid as if every such person had been duly
appointed and was qualified and had continued to be a Director and had been
entitled to vote.

99. A resolution in writing signed by all the Directors entitled to receive
notice of a meeting of Directors or of a committee of Directors shall be as
valid and effectual as if it had been passed at a meeting of Directors or (as
the case may be) a committee of Directors duly convened and held and may consist
of several documents in the like form each signed by one or more Directors, but
a resolution signed by an alternate need not also be signed by his appointor
and, if it is signed by a Director who has appointed an alternate Director, it
need not be signed by the alternate Director in that capacity.

100. Save as otherwise provided by the articles, a Director shall not vote at a
meeting of Directors or of a committee of Directors on any resolution concerning
a matter in which he has, directly or indirectly, an interest or duty which is
material and which conflicts or may conflict with the interest of the Company
unless he has declared the nature of his interest in the manner required by
Section 148 of the Act.

                                                                              35


101. A Director shall not be counted in the quorum present at a meeting in
relation to a resolution on which he is not entitled to vote.

102. The Company may by ordinary resolution suspend or relax to any extent,
either generally or in respect of any particular matter, any provision of the
articles prohibiting a Director from voting at a meeting of Directors or of a
committee of Directors.

103. If a question arises at a meeting of Directors or of a committee of
Directors as to the right of a Director to vote, the question may, before the
conclusion of the meeting, be referred to the Chairman of the meeting and his
ruling in relation to any Director other than himself shall be final and
conclusive.

104. Any Director or member of a committee of the Directors may participate in a
meeting of the Directors or such committee by means of telephonic or similar
communications whereby all persons participating in the meeting can hear each
other and participation in a meeting in this manner shall be deemed to
constitute presence in person at such meeting. The location of such a telephonic
meeting shall be deemed to be the place at which the Chairman of the meeting was
located at the time of the meeting.




                             MANAGEMENT AND CONTROL

105. The management and control of the business of the Company shall be in and

                                                                              36


                                    SECRETARY

106. Subject to the provisions of the Act, the secretary shall be appointed by
the Directors for such term, at such remuneration and upon such conditions as
they may think fit; and any secretary so appointed may be removed by them.



                                     MINUTES

107. The Directors shall cause Minutes to be made in books kept for the purpose
- -

                  (a) of all appointments of officers made by the Directors; and

                  (b) of all proceedings at meetings of the Company, of the
                  holders of any class of shares in the Company and of the
                  Directors, and of committees of Directors, including the names
                  of the Directors present at such meeting.


                                    THE SEAL

108. The Company shall have a Company Seal.

109. The seal shall only be used by the authority of the Directors or of a
committee of Directors authorised by the Directors. The Directors may determine
who shall sign any instrument to which the seal is affixed and unless otherwise
so determined it shall be signed by a Director and by the secretary or by a
second Director.

                                                                              37


                                    DIVIDENDS

110. Subject to the provisions of the Act, the Company may by ordinary
resolution declare dividends in accordance with the respective rights of the
members, but no dividend shall exceed the amount recommended by the Directors.

111. Subject to the provisions of the Act, the Directors may pay interim
dividends if it appears to them that they are justified by the profits of the
Company available for distribution. If the share capital is divided into
different classes, the Directors may pay interim dividends on shares which
confer deferred or non-preferred rights with regard to dividend as well as on
shares which confer preferential rights with regard to dividend, but no interim
dividend shall be paid on shares carrying deferred or non-preferential rights
if, at the time of payment, any preferential dividend is in arrear. The
Directors may also pay at intervals settled by them any dividend payable at a
fixed rate if it appears to them that the profits available for distribution
justify the payment. Provided the Directors act in good faith they shall not
incur any liability to the holders of shares conferring preferred rights for any
loss they may suffer by the lawful payment of an interim dividend on any shares
having deferred or non-preferred rights.

112. Except as otherwise provided by the rights attached to shares, all
dividends shall be declared and paid according to the amounts paid up on the
shares on which the dividend is paid. All dividends shall be apportioned and
paid proportionately to the amounts paid up on the shares during any portion or
portions of the period in respect of which the dividend is paid; but, if any
share is issued on terms providing that it shall rank for dividend as from a
particular date, that share shall rank for dividend accordingly.

113. A general meeting declaring a dividend may, upon the recommendation of the
Directors, direct that it shall be satisfied wholly or partly by the
distribution of assets


<PAGE>

                                                                              38


and where any difficulty arises in regard to the distribution, the Directors may
settle the same and in particular may issue fractional certificates and fix the
value for distribution of any assets and may determine that cash shall be paid
to any member upon the footing of the value so fixed in order to adjust the
rights of members and may vest any assets in trustees.

114. Any dividend or other moneys payable in respect of a share may be paid by
cheque sent by post to the registered address of the person entitled or, if two
or more persons are the holders of the share or are jointly entitled to it by
reason of the death or bankruptcy of the holder, to the registered address of
that one of those persons who is first named in the register of members or to
such person and to such address as the person or persons entitled may in writing
direct. Every cheque shall be made payable to the order of the person or persons
entitled or to such other person as the person or persons entitled may in
writing direct and payment of the cheque shall be a good discharge to the
Company. Any joint holder or other person jointly entitled to a share as
aforesaid may give receipts for any dividend or other moneys payable in respect
of the share.

115. No dividend or other moneys payable in respect of a share shall bear
interest against the Company unless otherwise provided by the rights attached to
the share.

116. Any dividend which has remained unclaimed for twelve years from the date
when it became due for payment shall, if the Directors so resolve, be forfeited
and cease to remain owing by the Company.


                                    ACCOUNTS

117.              (a) No member shall (as such) have any right of inspecting any
                  accounting records or other book or document of the Company
                  except as


<PAGE>

                                                                              39


                  conferred by statute or authorised by the Directors or by
                  ordinary resolution of the Company.

                  (b) The Company shall prepare such accounts as may be required
                  by the Act and the laws of the Isle of Man.

                  (c) Subject to the Act and the laws of the Isle of Man the
                  Company may elect to dispense with compliance with the
                  requirements of the Act which relate to the audit of the
                  accounts of the Company.


                            CAPITALISATION OF PROFITS

118. The Directors may with the authority of an ordinary resolution of the
Company -

                  (a) subject as hereinafter provided, resolve to capitalise any
                  undivided profits of the Company not required for paying any
                  preferential dividend (whether or not they are available for
                  distribution) or any sum standing to the credit of the
                  Company's share premium account or capital redemption reserve;

                  (b) appropriate the sum resolved to be capitalised to the
                  members who would have been entitled to it if it were
                  distributed by way of dividend and in the same proportions and
                  apply such sum on their behalf either in or towards paying up
                  the amounts, if any, for the time being unpaid on any shares
                  held by them respectively, or in paying up in full unissued
                  shares or debentures of the Company of a nominal amount, equal
                  to that sum, and allot the shares or debentures credited as
                  fully paid to those members, or as they may direct, in those
                  proportions, or partly in one way and partly in the other: but
                  the share premium account, the capital


<PAGE>

                                                                              40


                  redemption reserve and any profits which are not available for
                  distribution may, for the purposes of this regulation, only be
                  applied in paying up unissued shares to be allotted to members
                  credited as fully paid;

                  (c) make such provision by the issue of fractional
                  certificates or by payment in cash or otherwise as they
                  determine in the case of shares or debentures becoming
                  distributable under this regulation in fractions; and

                  (d) authorise any person to enter on behalf of all the members
                  concerned into an agreement with the Company providing for the
                  allotment to them respectively, credited as fully paid, of any
                  shares or debentures to which they are entitled upon such
                  capitalisation, any agreement made under such authority being
                  binding on all such members.


                                     NOTICES

119. Any notice to be given to or by any person pursuant to the articles shall
be in writing except that a notice calling a meeting of the Directors need not

120. The Company may give any notice to a member either personally or by sending
it by post in a prepaid envelope addressed to the member at his registered
address or by leaving it at that address. In the case of joint holders of a
share, all notices shall be given to the joint holder whose name stands first in
the register of members in respect of the joint holding and notice so given
shall be sufficient notice to all the joint holders. A member whose registered
address is not within the British Islands and who gives to the Company an
address within the British Islands at which notices may be given to him shall be
entitled to have notices given to him at that address, but otherwise no such
member shall be entitled to receive any notice from the Company.

                                                                              41


121. A member present, either in person or by proxy, at any meeting of the
Company or of the holders of any class of shares in the Company shall be deemed
to have received notice of the meeting and, where requisite, of the purposes for
which it was called.

122. Every person who becomes entitled to a share shall be bound by any notice
in respect of that share which, before his name is entered in the register of
members, has been duly given to a person from whom he derives his title.

123. Proof that an envelope containing a notice was properly addressed, prepaid
and posted shall be conclusive evidence that the notice was given. A notice
shall be deemed to be given at the expiration of 48 hours after the envelope
containing it was posted.

124. A notice may be given by the Company to the persons entitled to a share in
consequence of the death or bankruptcy of a member by sending or delivering it,
in any manner authorised by the articles for the giving of notice to a member,
addressed to them by name, or by the title of representatives of the deceased,
or trustee of the bankrupt or by any like description at the address, if any,
within the British Islands supplied for that purpose by the persons claiming to
be so entitled. Until such an address has been supplied, a notice may be given
in any manner in which it might have been given if the death or bankruptcy had
not occurred.


                                   WINDING UP

125. If the Company is wound up, the liquidator may, with the sanction of an
extraordinary resolution of the Company and any other sanction required by the
Act, divide among the members in specie the whole or any part of the assets of
the Company and may, for that purpose, value any assets and determine how the
division


<PAGE>

                                                                              42


shall be carried out as between the members or different classes of members. The
liquidator may, with the like sanction, vest the whole or any part of the assets
in trustees upon such trusts for the benefit of the members as he with the like
sanction determines, but no member shall be compelled to accept any assets upon
which there is a liability.


                                    INDEMNITY

126. Every Director or other officer of the Company shall be entitled to be
indemnified out of the assets of the Company against all losses or liabilities
(including any such liability as is mentioned in paragraph (c) of the proviso to
Section 151 of the Act) which he may sustain or incur in or about the execution
of the duties of his office or otherwise in relation thereto, and no Director or
other officer shall be liable for any loss, damage or misfortune which may
happen to or be incurred by the Company in the execution of the duties of his
office or in relation thereto. But this Article shall only have effect in so far
as its provisions are not avoided by the said Section.

127. The Company may purchase and maintain indemnity insurance for the benefit
of each Director or other officer of the Company.

<PAGE>

                                                                               7


(3) In these regulations, unless there is something in the subject of context
inconsistent with such construction:-

                  (a) words importing the plural number shall be deemed to
                  include the singular number and words importing the singular
                  number shall be deemed to include the plural number;

                  (b) words importing the masculine gender only include the
                  feminine gender;

                  (c) words importing persons include companies or associations

4. Statutory references used in these articles shall be read to include any

substitution therefor.


                                  SHARE CAPITAL

5.       (1) Subject to the provisions of the Act and without prejudice to any
         rights attached to any existing shares, any share may be issued with
         such rights or restrictions as the Company may by ordinary resolution
         determine.

         (2) Subject to the provisions of the Act, shares may be issued in
         fractional denominations to the same extent as whole shares.

6. Subject to the provisions of the Act and the articles, redeemable preference
shares may be issued on such terms and in such manner as may be provided by the
articles.


<PAGE>

                                                                               8


7. The Company may exercise the powers of paying commissions conferred by the
Act. Subject to the provisions of the Act, any such commissions may be satisfied
by the payment of cash or by the allotment of fully or partly paid shares or
partly in one way and partly in the other.

8. Except as required by law, no person shall be recognised by the Company as
holding any share upon any trust and (except as otherwise provided by the
articles or by law) the Company shall not be bound by or recognise any interest
in any share except an absolute right to the entirety thereof in the holder.

9. The shares shall be at the disposal of the Directors, and (save as otherwise
directed by the Company in General Meeting) they may allot or otherwise dispose
of them to such persons at such times and generally on such terms and conditions
as they think proper, subject nevertheless to article 2 and provided that no
shares shall be issued at a discount, except as provided by Section 47 of the
Act.

10. If at any time the share capital is divided into different classes of
shares, the rights attached to any class (unless otherwise provided by the terms
of issue of the shares of that class) may be varied with the consent in writing
of the holders of all of the issued shares of that class, or with the sanction
of an extraordinary resolution passed at a separate general meeting of the
holders of the shares of the class. To every such separate general meeting the
provisions of these regulations relating to general meetings shall in the case
of the number of holders of a particular class of shares being two or more
mutatis mutandis apply, but so that the necessary quorum shall be two persons at
least holding or representing by proxy one-third of the issued shares of the
class, and that any holder of shares of the class present in person or by proxy
may demand a poll. In the case of the number of holders of a particular class of
shares being one, one person holding or representing all the issued shares of
the class shall be a quorum.


<PAGE>

                                                                               9


11. The Company may issue share warrants to bearer in respect of any fully
paid-up shares of the Company, stating that the bearer of the warrant is
entitled to the shares therein specified. Such warrants shall be issued upon
such terms and subject to such conditions as may be resolved upon by the
Directors. Subject to the provisions of the Act and of these articles the holder
of a share warrant shall be deemed to be a member of the Company and shall be
entitled to the same rights and privileges as he would have had if his name had
been included in the share register of the Company as the holder of the shares.


                               SHARE CERTIFICATES

12.      (1) Every member, upon becoming the holder of any shares shall be
         entitled

                  (a) without payment, to one certificate for all the shares of
                  each class held by him (and, upon transferring a part of his
                  holding of shares of any class, to a certificate for the
                  balance of such holding); or

                  (b) to several certificates each for one or more of his shares
                  upon payment, for every certificate after the first, of such
                  reasonable sum as the Directors may determine.

         (2) Every certificate shall be sealed with the seal and shall specify
         the number, class and distinguishing numbers (if any) of the shares to
         which it relates and the amount or respective amounts paid up thereon.

         (3) The Company shall not be bound to issue more than one certificate
         for shares held jointly by several persons and delivery of a
         certificate to one joint holder shall be a sufficient delivery to all
         of them.


<PAGE>

                                                                              10


13. If a share certificate is defaced, worn-out, lost or destroyed, it may be
renewed on such terms (if any) as to evidence and indemnity and payment of the
expenses reasonably incurred by the Company in investigating evidence as the
Directors may determine but otherwise free of charge, and (in the case of
defacement or wearing-out) on delivery up of the old certificate.

14. The Company shall have a first and paramount lien on every share for all
moneys (whether presently payable or not) payable at a fixed time or called in
respect of that share. The Directors may at any time declare any share to be
wholly or in part exempt from the provisions of this regulation. The Company's
lien on a share shall extend to any amount payable in respect of it.

15. The Company may sell in such manner as the Directors determine any shares on
which the Company has a lien if a sum in respect of which the lien exists is
presently payable and is not paid within fourteen clear days after notice has
been given to the holder of the share or to the person entitled to it in
consequence of the death or bankruptcy of the holder, demanding payment and
stating that if the notice is not complied with the shares may be sold.

16. To give effect to a sale the Directors may authorise some person to execute
an instrument of transfer of the shares, sold to, or in accordance with the
directions of, the purchaser. The title of the transferee to the shares shall
not be affected by any irregularity in or invalidity of the proceedings in
reference to the sale.

17. The net proceeds of the sale, after payment of the costs, shall be applied
in payment of so much of the sum for which the lien exists as is presently
payable, and any residue shall (upon surrender to the Company for cancellation
of the certificate for the shares sold and subject to a like lien for any moneys
not presently payable as existed upon the shares before the sale) be paid to the
person entitled to the shares at the date of the sale.


<PAGE>

                                                                              11


                         CALLS ON SHARES AND FORFEITURE

18. Subject to the terms of allotment, the Directors may make calls upon the
members in respect of any moneys unpaid on their shares (whether in respect of
nominal value or premium) and each member shall (subject to receiving at least
fourteen clear days notice specifying when and where payment is to be made) pay
to the Company as required by the notice the amount called on his shares. A call
may be required to be paid by instalments. A call may, before receipt by the
Company of any sum due thereunder, be revoked in whole or in part and payment of
a call may be postponed in whole or in part. A person upon whom a call is made
shall remain liable for calls made upon him notwithstanding the subsequent
transfer of the shares in respect whereof the call was made.

19. A call shall be deemed to have been made at the time when the resolution of
the Directors authorising the call was passed.

20. The joint holders of a share shall be jointly and severally liable to pay
all calls in respect thereof.

21. If a call remains unpaid after it has become due and payable the person from
whom it is due and payable shall pay interest on the amount unpaid from the day
it became due and payable until it is paid at the rate fixed by the terms of
allotment of the share or in the notice of the call or, if no rate is fixed, at
the rate of (pound)5 per centum per annum but the Directors may waive payment of
the interest wholly or in part.

22. An amount payable in respect of a share on allotment or at any fixed date,
whether in respect of nominal value or premium or as an instalment of a call,
shall be deemed to be a call and if it is not paid the provisions of the
articles shall apply as if that amount had become due and payable by virtue of a
call.


<PAGE>

                                                                              12


23. Subject to the terms of allotment, the Directors may make arrangements on
the issue of shares for a difference between the holders in the amounts and
times of payment of calls on their shares.

24. If a call remains unpaid after it has become due and payable the Directors
may give to the person from whom it is due not less than fourteen clear days'
notice requiring payment of the amount unpaid together with any interest which
may have accrued. The notice shall name the place where payment is to be made
and shall state that if the notice is not complied with the shares in respect of
which the call was made will be liable to be forfeited.

25. If the notice is not complied with any share in respect of which it was
given may, before the payment required by the notice has been made, be forfeited
by a resolution of the Directors and the forfeiture shall include all dividends
or other moneys payable in respect of the forfeited shares and not paid before
the forfeiture.

26. Subject to the provisions of the Act, a forfeited share may be sold,
re-allotted or otherwise disposed of on such terms and in such manner as the
Directors determine either to the person who was before the forfeiture the
holder or to any other person and at any time before sale, re-allotment or other
disposition, the forfeiture may be cancelled on such terms as the Directors
think fit. Where for the purposes of its disposal a forfeited share is to be
transferred to any person the Directors may authorise some person to execute an
instrument of transfer of the share to that person.

27. A person any of whose shares have been forfeited shall cease to be a member
in respect of them and shall surrender to the Company for cancellation the
certificate for the shares forfeited but shall remain liable to the Company for
all moneys which at the date of forfeiture were presently payable by him to the
Company in respect of those shares with interest at the rate at which interest
was payable on those moneys before the forfeiture or, if no interest was so
payable, at the rate of (pound)5 per centum per annum


<PAGE>

                                                                              13


from the date of forfeiture until payment but the Directors may waive payment
wholly or in part or enforce payment without any allowance for the value of the
shares at the time of forfeiture or for any consideration received on their
disposal.

28. A statutory declaration by a Director or the secretary that a share has been
forfeited on a specified date shall be conclusive evidence of the facts stated
in it as against all persons claiming to be entitled to the share and the
declaration shall (subject to the execution of an instrument of transfer if
necessary) constitute a good title to the share and the person to whom the share
is disposed of shall not be bound to see to the application of the
consideration, if any, nor shall his title to the share be affected by any
irregularity in or invalidity of the proceedings in reference to the forfeiture
or disposal of the share.


                               TRANSFER OF SHARES

29. The instrument of transfer of a share may be in any usual form or in any
other form which the Directors may approve and shall be executed by or on behalf
of the transferor and, unless the share is fully paid, by or on behalf of the
transferee.

30. No transfer of any share in the capital of the Company to any person not
already a member of the Company shall be made or registered without the previous
sanction of the Directors, who may without assigning any reason, decline to give
any such sanction. The Directors may also suspend the registration of transfers
during the fourteen days immediately preceding the Ordinary General Meeting in
each year. The Directors may decline to recognise any instrument of transfer
unless accompanied by the certificate of the shares to which it relates, and
such other evidence as the Directors may reasonably require to show the right of
the transferor to make the transfer. The Directors may decline to register a
transfer of any shares on which the Company has a lien. If the Directors refuse
to register a transfer of any share they


<PAGE>

                                                                              14


shall within two months after the date on which the transfer was lodged with the
Company send to the transferee notice of the refusal as required by section 67
of the Act.

31. The Company shall be entitled to retain any instrument of transfer which is
registered, but any instrument of transfer which the Directors refuse to
register shall be returned to the person lodging it when notice of the refusal
is given.


                             TRANSMISSION OF SHARES

32. If a member dies the survivor or survivors where he was a joint holder, and
his personal representatives where he was a sole holder or the only survivor of
joint holders, shall be the only persons recognised by the Company as having any
title to his interest; but nothing herein contained shall release the estate of
a deceased member from any liability in respect of any share which had been
jointly held by him.

33. A person becoming entitled to a share in consequence of the death or
bankruptcy of a member may, upon such evidence being produced as the Directors
may properly require, elect either to become the holder of the share or to have
some person nominated by him registered as the transferee. If he elects to
become the holder he shall give notice to the Company to that effect. If he
elects to have another person registered he shall execute an instrument of
transfer of the share to that person. All articles relating to the transfer of
shares shall apply to the notice or instrument of transfer as if it were an
instrument of transfer executed by the member and the death or bankruptcy of the
member had not occurred.

34. A person becoming entitled to a share in consequence of the death or
bankruptcy of a member shall have the rights to which he would be entitled if he
were the holder of the share, except that he shall not, before being registered
as the holder


<PAGE>

                                                                              15


of the share, be entitled in respect of it to attend or vote at any meeting of
the Company or at any separate meeting of the holders of any class of shares in
the Company.


                           ALTERATION OF SHARE CAPITAL

35. The Company may by ordinary resolution -

                  (a) increase its share capital by new shares of such amount as
                  the resolution prescribes;

                  (b) consolidate and divide all or any or its share capital
                  into shares of larger amount than its existing shares;

                  (c) subject to the provisions of the Act, sub-divide its
                  shares, or any of them, into shares of smaller amount and the
                  resolution may determine that, as between the shares resulting
                  from the sub-division, any of them may have any preference or
                  advantage as compared with the others; and

                  (d) cancel shares which, at the date of the passing of the
                  resolution, have not been taken or agreed to be taken by any
                  person and diminish the amount of its share capital by the
                  amount of the shares so cancelled.

36. Whenever as a result of a consolidation of shares any members would become
entitled to fractions of a share, the Directors may, instead of issuing the
fractions of a share, on behalf of those members, sell the shares representing
the fractions for the best price reasonably obtainable to any person (including,
subject to the provisions of the Act, the Company) and distribute the net
proceeds of sale in due proportion among those members, and the Directors may
authorise some person to execute an instrument of transfer of the shares to, or
in accordance with the directions of, the purchaser. The

                                                                              16


transferee shall not be bound to see to the application of the purchase money
nor shall his title to the shares be affected by any irregularity in or
invalidity of the proceedings in reference to the sale.

37. Subject to the provisions of the Act, the Company may by special resolution
reduce its share capital, any capital redemption reserve and any share premium
account in any way.


                         CONVERSION OF SHARES INTO STOCK

38. The Company may by ordinary resolution convert any paid-up shares into stock
and reconvert any stock into paid-up shares of any denomination.

39. The holders of stock may transfer the same, or any part thereof, in the same
manner, and subject to the same regulations, as, and subject to which, the
shares from which the stock arose might previously to conversion have been
transferred, or as near thereto as circumstances admit; but the Directors may
from time to time fix the minimum amount of stock transferable and restrict or
forbid the transfer of fractions of that minimum, but the minimum shall not
exceed the nominal amount of the shares from which the stock arose.

40. The holders of stock shall, according to the amount of the stock held by
them, have the same rights, privileges and advantages as regards dividends,
voting at meetings of the Company and other matters as if they held the shares
from which the stock arose, but no such privilege or advantage (except
participation in the dividends and profits of the Company) shall be conferred by
any such aliquot part of stock as would not, if existing in shares, have
conferred that privilege or advantage.

                                                                              17


41. Such of the regulations of the Company as are applicable to paid-up shares
shall apply to stock and the words "shares" and "shareholder" therein shall
include "stock" and "stockholder".


                         REDEMPTION OF PREFERENCE SHARES

42. Subject to the provisions of the Act, the redemption of redeemable
preference shares shall be effected on such terms and in such manner, as may be
provided by the articles.


                                GENERAL MEETINGS

43. All general meetings other than annual general meetings shall be called
extraordinary general meetings.

44. The Directors may call general meetings, and on the requisition of a member
pursuant to the provisions of the Act, shall forthwith proceed to convene an
extraordinary general meeting for a date not later than eight weeks after
receipt of the requisition. If there are not within the Isle of Man sufficient
Directors to call a general meeting, any Director or any member of the Company
may call a general meeting.


                           NOTICE OF GENERAL MEETINGS

45. An annual general meeting and an extraordinary general meeting called for
the passing of a special resolution or a resolution appointing a person as a

extraordinary general


<PAGE>

                                                                              18


meetings shall be called by at least fourteen clear days' notice but a general
meeting may be called by shorter notice if it is so agreed -

                  (a) In the case of an annual general meeting, by all the
                  members entitled to attend and vote thereat; and

                  (b) In the case of any other meeting by a majority in number
                  of the members having a right to attend and vote being a
                  majority together holding not less than ninety five per cent
                  in nominal value of the shares giving that right.

The notice shall specify the time and place of the meeting and the general
nature of the business to be transacted and, in the case of an annual general
meeting, shall specify the meeting as such.

Subject to the provisions of the articles and to any restrictions imposed on any
shares, the notice shall be given to all the members, to all persons entitled to
a share in consequence of the death or bankruptcy of a member and to the
Directors and auditors.

46. The accidental omission to give notice of a meeting to or the non-receipt of
notice of a meeting by any person entitled to receive notice shall not
invalidate the proceedings at that meeting.


                         PROCEEDINGS AT GENERAL MEETINGS

47. No business shall be transacted at any meeting unless a quorum is present.
Two persons entitled to vote upon the business to be transacted, each being a
member or a proxy for a member or a duly authorised representative of a
corporation which is a member, shall be a quorum. When the Company has a single
member, the member


<PAGE>

                                                                              19


or the proxy for the member or a duly authorised representative of the
corporation which is the member, shall be a quorum.

48. If such a quorum is not present within half an hour from the time appointed
for the meeting or if during a meeting such a quorum ceases to be present, the
meeting shall stand adjourned to the same day in the next week at the same time
and place or to such time and place as the Directors may determine.

49. The Chairman, if any, of the Board of Directors or in his absence some other
Director nominated by the Directors shall preside as Chairman of the meeting,
but if neither the Chairman nor such other Director (if any) be present within
fifteen minutes after the time appointed for holding the meeting and willing to
act, the Directors present shall elect one of their number to be Chairman and if
there is only one Director present and willing to act, he shall be Chairman.

50. If no Director is willing to act as Chairman, or if no Director is present
within fifteen minutes after the time appointed for holding the meeting, the
members present and entitled to vote shall choose one of their number to be
Chairman.

51. A Director shall, notwithstanding that he is not a member, be entitled to
attend and speak at any general meeting and at any separate meeting of the
holders of any class of shares in the Company.

52. The Chairman may, with the consent of a meeting at which a quorum is present
(and shall if so directed by the meeting), adjourn the meeting from time to time
and from place to place, but no business shall be transacted at an adjourned
meeting other than business which might properly have been transacted at the
meeting had the adjournment not taken place. When a meeting is adjourned for
fourteen days or more, at least seven clear days' notice shall be given
specifying the time and place of the


<PAGE>

                                                                              20


adjourned meeting and the general nature of the business to be transacted.
Otherwise it shall not be necessary to give any such notice.

53. A resolution put to the vote of a meeting shall be decided on a show of
hands unless before, or on the declaration of the result of, the show of hands a
poll is duly demanded. Subject to the provisions of the Act, a poll may be
demanded -

         (a) by the Chairman; or

                  (b) by at least two members having the right to vote at the
                  meeting; or

                  (c) by a member or members representing no less than one-tenth
                  of the total voting rights of all the members having the right
                  to vote at the meeting; or

                  (d) by a member or members holding shares conferring a right
                  to vote at the meeting being shares on which an aggregate sum
                  has been paid up equal to not less than one-tenth of the total
                  sum paid up on all the shares conferring that right;

and a demand by a person as proxy for a member shall be the same as a demand by
the member.

54. Unless a poll is duly demanded a declaration by the Chairman that a
resolution has been carried or carried unanimously, or by a particular majority,
or lost, or not carried by a particular majority and an entry to that effect in
the minutes of the meeting shall be conclusive evidence of the fact without
proof of the number or proportion of the votes recorded in favour of or against
the resolution.


<PAGE>

                                                                              21


55. The demand for a poll may, before the poll is taken, be withdrawn but only
with the consent of the Chairman and a demand so withdrawn shall not be taken to
have invalidated the result of a show of hands declared before the demand was
made.

56. A poll shall be taken as the Chairman directs and he may appoint scrutineers
(who need not be members) and fix a time and place for declaring the result of
the poll. The result of the poll shall be deemed to be the resolution of the
meeting at which the poll was demanded.

57. In the case of an equality of votes, whether on a show of hands or on a
poll, the Chairman shall be entitled to a casting vote in addition to any other
vote he may have.

58. A poll demanded on the election of a Chairman or on a question of
adjournment shall be taken forthwith. A poll demanded on any other question
shall be taken either forthwith or at such time and place as the Chairman
directs not being more than thirty days after the poll is demanded. The demand
for a poll shall not prevent the continuance of a meeting for the transaction of
any business other than the question on which the poll was demanded. If a poll
is demanded before the declaration of the result of a show of hands and the
demand is duly withdrawn, the meeting shall continue as if the demand had not
been made.

59. No notice need be given of a poll not taken forthwith if the time and place
at which it is to be taken are announced at the meeting at which it is demanded.
In any other case at least seven clear days notice shall be given specifying the
time and place at which the poll is to be taken.

60. A resolution in writing executed by or on behalf of each member who would
have been entitled to vote upon it if it had been proposed at a general meeting
at which he was present shall be as effectual as if it had been passed at a
general meeting duly convened and held and may consist of several instruments in
the like form each


<PAGE>

                                                                              22


executed by or on behalf of one or more members, provided the provisions of
Section 118B of the Act are complied with and that such resolution is received
by the Company at its registered office within seven days of the date of its
execution in terms hereof.





                                VOTES OF MEMBERS

61. Subject to any rights or restrictions attached to any shares, on a show of
hands every member who (being an individual) is present in person or by proxy or
(being a corporation) is present by a duly authorised representative, not being
himself a member, shall have one vote and on a poll every member entitled to
vote shall have one vote for every share of which he is the holder.

62. In the case of joint holders the vote of the senior who tenders a vote,
whether in person or by proxy, shall be accepted to the exclusion of the votes
of the other joint holders; and seniority shall be determined by the order in
which the names of the holders stand in the register of members.

63. A member in respect of whom an order has been made by any court having
jurisdiction (whether in the Isle of Man or elsewhere) in matters concerning
mental disorder may vote, whether on a show of hands or on a poll, by his
receiver, curator bonis or other person authorised in that behalf appointed by
that court, and any such receiver, curator bonis or other person may, on a poll,
vote by proxy. Evidence to the satisfaction of the Directors of the authority of
the person claiming to exercise the right to vote shall be deposited at the
office, or at such other place as is specified in accordance with the articles
for the deposit of instruments of proxy, not less than 48 hours before the time
appointed for holding the meeting or adjourned meeting at which


<PAGE>

                                                                              23


the right to vote is to be exercised and in default the right to vote shall not
be exercisable.

64. No member shall vote at any general meeting or at any separate meeting of
the holders of any class of shares in the Company, either in person or by proxy,
in respect of any share held by him unless all moneys presently payable by him
in respect of that share have been paid.

65. No objections shall be raised to the qualification of any voter except at
the meeting or adjourned meeting at which the vote objected to is tendered, and
every vote not disallowed at the meeting shall be valid. Any objection made in
due time shall be referred to the Chairman whose decision shall be final and
conclusive.

66. On a poll votes may be given either personally or by proxy. A member may
appoint more than one proxy to attend on the same occasion.

67. An instrument appointing a proxy shall be in writing, executed by or on
behalf of the appointor and shall be in the following form (or in a form as near
thereto as circumstances allow or in any other form which is usual or which the
Directors may approve) -

                                     Limited

approved by the Directors may-

                  (a) be deposited at the office or at such other place within
                  the Isle of Man as is specified in the notice convening the
                  meeting or in any instrument of proxy sent out by the Company
                  in relation to the meeting not less than 48 hours before the

                  meeting at which the poll was demanded, to the Chairman or to
                  the Secretary or to any Director;

and an instrument of proxy which is not deposited or delivered in a manner so
permitted shall be invalid.

70. A vote given or poll demanded by proxy or by the duly authorised
representative of a corporation shall be valid notwithstanding the previous
determination of the authority of the person voting or demanding a poll unless
notice of the determination was received by the Company at the office or at such
other place at which the instrument of proxy was duly deposited before the
commencement of the meeting or adjourned meeting at which the vote is given or
the poll demanded or (in the case of


<PAGE>

                                                                              26


a poll taken otherwise than on the same day as the meeting or adjourned meeting)
the time appointed for taking the poll.

71. Where the Company is a single member company and the sole member takes any
decision which may be taken by the Company in general meeting and which has
effect as if agreed by the Company in general meeting he shall subject to
article 60 provide the Company with a written record of that decision by
forwarding such record to the Company at its registered office within seven days
of the date upon which the decision was taken.




                               NUMBER OF DIRECTORS

72. Unless otherwise determined by ordinary resolution, the number of Directors
(other than alternate Directors) shall not be subject to any maximum.


                               ALTERNATE DIRECTORS

73. Any Director (other than an alternate Director) may appoint any other
Director, or any other person approved by resolution of the Directors and
willing to act, to be an alternate Director and may remove from office an
alternate Director so appointed by him.

74. An alternate Director shall be entitled to receive notice of all meetings of
Directors and of all meetings of committees of Directors of which his appointor

functions of his appointor as


<PAGE>

                                                                              27


a Director in his absence but shall not be entitled to receive any remuneration
from the Company for his services as an alternate Director.

75. An alternate Director shall cease to be an alternate Director if his
appointor ceases to be a Director; but, if a Director retires by rotation or
otherwise but is reappointed or deemed to have been reappointed at the meeting
at which he retires; any appointment of an alternate Director made by him which
was in force immediately prior to his retirement shall continue after his
reappointment.

76. Any appointment or removal of an alternate Director shall be by notice to
the Company signed by the Director making or revoking the appointment or in any
other manner approved by the Directors.

77. Save as otherwise provided in the articles, an alternate Director shall be
deemed for all purposes to be a Director and shall alone be responsible for his
own acts and defaults and he shall not be deemed to be the agent of the Director
appointing him.


                               POWERS OF DIRECTORS

78. Subject to the provisions of the Act, the memorandum and the articles and to
any directions given by special resolution the business of the Company shall be
managed by the Directors who may exercise all the powers of the Company. No
alteration of the memorandum or articles and no such direction shall invalidate
any prior act of the Directors which would have been valid if that alteration
had not been made or that direction had not been given. The powers given by this
regulation shall not be limited by any special power given to the Directors by
the articles and a meeting of Directors at which a quorum is present may
exercise all powers exercisable by the Directors.

                                                                              28


79. Without prejudice to the generality of the foregoing article the Directors
may from time to time at their discretion, raise or borrow, without the consent
of the members in General Meeting, such sum or sums of money for the purposes of
the Company's business as they may think fit and may secure the repayment of or
raise any such sum or sums as aforesaid in such manner and upon such terms and
conditions and in all other respects as they may think fit, and in particular by
mortgages, deeds of bond and security, or other charges upon the whole or any
part of the property and assets of the Company, present or future, including its
uncalled or unissued capital, or by the issue at such price as they may think
fit, of bonds or debentures or debenture stock of the Company, either charged
upon the whole or any part of the property and assets of the Company, or not so
charged, or in any other way that the Directors may think expedient, and the
Directors may issue debentures or debenture stock or paid-up shares to any
person or persons as consideration for the purchase of any goodwill, business or
property purchased by the Company.

80. The Directors may, by power of attorney or otherwise, appoint any person to
be the agent of the Company for such purposes and on such conditions as they
determine, including authority for the agent to delegate all or any of his
powers. The Company may exercise the powers conferred by Sections 32 and 104 of
the Companies Act, 1931 and those powers shall accordingly be exercisable by the
Directors.

81. The Directors may delegate any of their powers to any committee consisting
of one or more Directors. They may also delegate to any Managing Director or any
Director holding any other executive office such of their powers as they
consider desirable to be exercised by him. Any such delegation may be made
subject to any conditions the Directors may impose and either collaterally with
or to the exclusion of their own powers and may be revoked or altered. Subject
to any such conditions, the

proceedings of a committee with two or more members shall be governed by the
articles regulating the proceedings of Directors so far as they are capable of
applying.


                               DIRECTORS GENERALLY

82. The Company may from time to time in general meeting increase or reduce the
number of Directors. The Company may by special resolution remove any Director
or by ordinary resolution appoint any person to be a Director.

83. No person other than a first Director shall be appointed a Director in
general meeting unless at least seven days' and not more than fourteen days'
notice shall have been left at the registered office of the Company of the
intention to propose him, together with a notice in writing by the person to be
proposed of his willingness to be appointed.

84. The Directors shall have power at any time, and from time to time, to fill
any casual vacancy occurring in the Board of Directors or to appoint a person as

                           (whether in the Isle of Man or elsewhere) in matters
                           concerning mental disorder for his detention or for
                           the appointment of a receiver, curator bonis or other

                  that his office be vacated.

88. The shareholding qualification for Directors may be fixed by the Company in
general meeting, and unless and until so fixed no qualification shall be
required.

                                                                              31


                      DIRECTORS' APPOINTMENTS AND INTERESTS

89. Subject to the provisions of the Act, the Directors may appoint one or more
of their number to the office of Managing Director or to any other executive
office under the Company and may enter into an agreement or arrangement with any
Director for his employment by the Company or for the provision by him of any
services outside the scope of the ordinary duties of a Director. Any such
appointment, agreement or arrangement may be made upon such terms as the
Directors determine and they may remunerate any such Director for his services
as they think fit. Any appointment of a Director to an executive office shall
terminate if he ceases to be a Director but without prejudice to any claim to
damages for breach of the contract of service between the Director and the
Company.

90. Subject to the provisions of the Act and provided that he has disclosed to
the Directors the nature and extent of any material interest of his, a Director
notwithstanding his office -


                  (a) may be a party to, or otherwise interested in, any
                  transaction or arrangement with the Company or in which the
                  Company is otherwise interested;

                  (b) may be a Director or other officer of, or employed by, or
                  a party to any transaction or arrangement with, or otherwise
                  interested in, any body corporate promoted by the Company or
                  in which the Company is otherwise interested; and

                  (c) shall not, by reason of his office, be accountable to the
                  Company for any benefit which he derives from any such office
                  or employment or


<PAGE>

                                                                              32


                  from any such transaction or arrangement or from any interest
                  in any such body corporate and no such transaction or
                  arrangement shall be liable to be avoided on the ground of any
                  such interest or benefit.

91. For the purposes of the foregoing article -

                  (a) a general notice given to the Directors that a Director is
                  to be regarded as having an interest of the nature and extent
                  specified in the notice in any transaction or arrangement in
                  which a specified person or class of persons is interested
                  shall be deemed to be a disclosure that the Director has an
                  interest in any such transaction of the nature and extent so
                  specified; and

                  (b) an interest of which a Director has no knowledge and of
                  which it is unreasonable to expect him to have knowledge shall
                  not be treated as an interest of his.

92. Subject to article 90 hereof and the Act if the Company is a single member
company and having one member it enters into a contract with the sole member
otherwise than in the ordinary course of the Company's business and the sole
member is also a director of the Company, the Company should, unless the
contract is in writing, ensure that the terms of the contract are either set out
in a written memorandum or are recorded in the minutes of the first meeting of
the directors of the Company following the making of the contract.


                       DIRECTORS' GRATUITIES AND PENSIONS

93. Subject to the provisions of the Act, the Directors may provide benefits,
whether by the payment of gratuities or pensions or by insurance or otherwise,
for any Director


<PAGE>

                                                                              33


who has held but no longer holds any executive office or employment with the
Company or with any body corporate which is or has been a subsidiary of the
Company or a predecessor of the Company or of any such subsidiary and for any
member of his family (including a spouse and a former spouse) or any person who
is or was dependent on him, and may (as well before as after he ceases to hold
such office or employment) contribute to any fund and pay premiums for the
purchase or provision of any such benefit.


                            PROCEEDINGS OF DIRECTORS

94. Subject to the provisions of the articles, the Directors may regulate their
proceedings as they think fit. A Director may, and the secretary at the request
of a Director shall, call a meeting of the Directors. Questions arising at a
meeting shall be decided by a majority of votes. In the case of an equality of
votes, the Chairman shall have a second or casting vote. A Director who is also
an alternate Director shall be entitled in the absence of his appointor to a
separate vote on behalf of his appointor in addition to his own vote.

95. The quorum for the transaction of the business of the Directors may be fixed
by the Directors and unless so fixed at any other number shall be two. A person
who holds office only as an alternate Director shall, if his appointor is not
present, be counted in the quorum.

96. The continuing Directors or a sole continuing Director may act
notwithstanding any vacancies in their number, but, if the number of Directors
is less than the number fixed as the quorum, the continuing Directors or
Director may act only for the purpose of filling vacancies or of calling a
general meeting.


<PAGE>

                                                                              34


97. The Directors may appoint one of their number to be the Chairman of the
Board of Directors and may at any time remove him from that office. Unless he is
unwilling to do so, the Director so appointed shall preside at every meeting of
Directors at which he is present. But if there is no Director holding that
office, or if the Director holding it is unwilling to preside or is not present
within five minutes after the time appointed for the meeting, the Directors
present may appoint one of their number to be Chairman of the meeting.

98. All acts done by a meeting of Directors, or of a committee of Directors, or
by a person acting as a Director shall, notwithstanding that it be afterwards
discovered that there was a defect in the appointment of any Director or that
any of them were disqualified from holding office, or had vacated office, or
were not entitled to vote, be valid as if every such person had been duly
appointed and was qualified and had continued to be a Director and had been
entitled to vote.

99. A resolution in writing signed by all the Directors entitled to receive
notice of a meeting of Directors or of a committee of Directors shall be as
valid and effectual as if it had been passed at a meeting of Directors or (as
the case may be) a committee of Directors duly convened and held and may consist
of several documents in the like form each signed by one or more Directors, but
a resolution signed by an alternate need not also be signed by his appointor
and, if it is signed by a Director who has appointed an alternate Director, it
need not be signed by the alternate Director in that capacity.

100. Save as otherwise provided by the articles, a Director shall not vote at a
meeting of Directors or of a committee of Directors on any resolution concerning
a matter in which he has, directly or indirectly, an interest or duty which is
material and which conflicts or may conflict with the interest of the Company
unless he has declared the nature of his interest in the manner required by
Section 148 of the Act.

                                                                              35


101. A Director shall not be counted in the quorum present at a meeting in
relation to a resolution on which he is not entitled to vote.

102. The Company may by ordinary resolution suspend or relax to any extent,
either generally or in respect of any particular matter, any provision of the
articles prohibiting a Director from voting at a meeting of Directors or of a
committee of Directors.

103. If a question arises at a meeting of Directors or of a committee of
Directors as to the right of a Director to vote, the question may, before the
conclusion of the meeting, be referred to the Chairman of the meeting and his
ruling in relation to any Director other than himself shall be final and
conclusive.

104. Any Director or member of a committee of the Directors may participate in a
meeting of the Directors or such committee by means of telephonic or similar
communications whereby all persons participating in the meeting can hear each
other and participation in a meeting in this manner shall be deemed to
constitute presence in person at such meeting. The location of such a telephonic
meeting shall be deemed to be the place at which the Chairman of the meeting was
located at the time of the meeting.




                             MANAGEMENT AND CONTROL

105. The management and control of the business of the Company shall be in and
from the Isle of Man or in and from such other place as the Directors shall
decide.

                                                                              36


                                    SECRETARY

106. Subject to the provisions of the Act, the secretary shall be appointed by
the Directors for such term, at such remuneration and upon such conditions as
they may think fit; and any secretary so appointed may be removed by them.



                                     MINUTES

107. The Directors shall cause Minutes to be made in books kept for the purpose
- -

                  (a) of all appointments of officers made by the Directors; and

                  (b) of all proceedings at meetings of the Company, of the
                  holders of any class of shares in the Company and of the
                  Directors, and of committees of Directors, including the names
                  of the Directors present at such meeting.


                                    THE SEAL

108. The Company shall have a Company Seal.

109. The seal shall only be used by the authority of the Directors or of a
committee of Directors authorised by the Directors. The Directors may determine
who shall sign any instrument to which the seal is affixed and unless otherwise
so determined it shall be signed by a Director and by the secretary or by a
second Director.

                                                                              37


                                    DIVIDENDS

110. Subject to the provisions of the Act, the Company may by ordinary
resolution declare dividends in accordance with the respective rights of the
members, but no dividend shall exceed the amount recommended by the Directors.

111. Subject to the provisions of the Act, the Directors may pay interim
dividends if it appears to them that they are justified by the profits of the
Company available for distribution. If the share capital is divided into
different classes, the Directors may pay interim dividends on shares which
confer deferred or non-preferred rights with regard to dividend as well as on
shares which confer preferential rights with regard to dividend, but no interim
dividend shall be paid on shares carrying deferred or non-preferential rights
if, at the time of payment, any preferential dividend is in arrear. The
Directors may also pay at intervals settled by them any dividend payable at a
fixed rate if it appears to them that the profits available for distribution
justify the payment. Provided the Directors act in good faith they shall not
incur any liability to the holders of shares conferring preferred rights for any
loss they may suffer by the lawful payment of an interim dividend on any shares
having deferred or non-preferred rights.

112. Except as otherwise provided by the rights attached to shares, all
dividends shall be declared and paid according to the amounts paid up on the
shares on which the dividend is paid. All dividends shall be apportioned and
paid proportionately to the amounts paid up on the shares during any portion or
portions of the period in respect of which the dividend is paid; but, if any
share is issued on terms providing that it shall rank for dividend as from a
particular date, that share shall rank for dividend accordingly.

113. A general meeting declaring a dividend may, upon the recommendation of the
Directors, direct that it shall be satisfied wholly or partly by the
distribution of assets


<PAGE>

                                                                              38


and where any difficulty arises in regard to the distribution, the Directors may
settle the same and in particular may issue fractional certificates and fix the
value for distribution of any assets and may determine that cash shall be paid
to any member upon the footing of the value so fixed in order to adjust the
rights of members and may vest any assets in trustees.

114. Any dividend or other moneys payable in respect of a share may be paid by
cheque sent by post to the registered address of the person entitled or, if two
or more persons are the holders of the share or are jointly entitled to it by
reason of the death or bankruptcy of the holder, to the registered address of
that one of those persons who is first named in the register of members or to
such person and to such address as the person or persons entitled may in writing
direct. Every cheque shall be made payable to the order of the person or persons
entitled or to such other person as the person or persons entitled may in
writing direct and payment of the cheque shall be a good discharge to the
Company. Any joint holder or other person jointly entitled to a share as
aforesaid may give receipts for any dividend or other moneys payable in respect
of the share.

115. No dividend or other moneys payable in respect of a share shall bear
interest against the Company unless otherwise provided by the rights attached to
the share.

116. Any dividend which has remained unclaimed for twelve years from the date
when it became due for payment shall, if the Directors so resolve, be forfeited
and cease to remain owing by the Company.


                                    ACCOUNTS

117.              (a) No member shall (as such) have any right of inspecting any
                  accounting records or other book or document of the Company
                  except as


<PAGE>

                                                                              39


                  conferred by statute or authorised by the Directors or by
                  ordinary resolution of the Company.

                  (b) The Company shall prepare such accounts as may be required
                  by the Act and the laws of the Isle of Man.

                  (c) Subject to the Act and the laws of the Isle of Man the
                  Company may elect to dispense with compliance with the
                  requirements of the Act which relate to the audit of the
                  accounts of the Company.


                            CAPITALISATION OF PROFITS

118. The Directors may with the authority of an ordinary resolution of the
Company -

                  (a) subject as hereinafter provided, resolve to capitalise any
                  undivided profits of the Company not required for paying any
                  preferential dividend (whether or not they are available for
                  distribution) or any sum standing to the credit of the
                  Company's share premium account or capital redemption reserve;

                  (b) appropriate the sum resolved to be capitalised to the
                  members who would have been entitled to it if it were
                  distributed by way of dividend and in the same proportions and
                  apply such sum on their behalf either in or towards paying up
                  the amounts, if any, for the time being unpaid on any shares
                  held by them respectively, or in paying up in full unissued
                  shares or debentures of the Company of a nominal amount, equal
                  to that sum, and allot the shares or debentures credited as
                  fully paid to those members, or as they may direct, in those
                  proportions, or partly in one way and partly in the other: but
                  the share premium account, the capital


<PAGE>

                                                                              40


                  redemption reserve and any profits which are not available for
                  distribution may, for the purposes of this regulation, only be
                  applied in paying up unissued shares to be allotted to members
                  credited as fully paid;

                  (c) make such provision by the issue of fractional
                  certificates or by payment in cash or otherwise as they
                  determine in the case of shares or debentures becoming
                  distributable under this regulation in fractions; and

                  (d) authorise any person to enter on behalf of all the members
                  concerned into an agreement with the Company providing for the
                  allotment to them respectively, credited as fully paid, of any
                  shares or debentures to which they are entitled upon such
                  capitalisation, any agreement made under such authority being
                  binding on all such members.


                                     NOTICES

119. Any notice to be given to or by any person pursuant to the articles shall
be in writing except that a notice calling a meeting of the Directors need not
be in writing.

120. The Company may give any notice to a member either personally or by sending
it by post in a prepaid envelope addressed to the member at his registered
address or by leaving it at that address. In the case of joint holders of a
share, all notices shall be given to the joint holder whose name stands first in
the register of members in respect of the joint holding and notice so given
shall be sufficient notice to all the joint holders. A member whose registered
address is not within the British Islands and who gives to the Company an
address within the British Islands at which notices may be given to him shall be
entitled to have notices given to him at that address, but otherwise no such
member shall be entitled to receive any notice from the Company.

                                                                              41


121. A member present, either in person or by proxy, at any meeting of the
Company or of the holders of any class of shares in the Company shall be deemed
to have received notice of the meeting and, where requisite, of the purposes for
which it was called.

122. Every person who becomes entitled to a share shall be bound by any notice
in respect of that share which, before his name is entered in the register of
members, has been duly given to a person from whom he derives his title.

123. Proof that an envelope containing a notice was properly addressed, prepaid
and posted shall be conclusive evidence that the notice was given. A notice
shall be deemed to be given at the expiration of 48 hours after the envelope
containing it was posted.

124. A notice may be given by the Company to the persons entitled to a share in
consequence of the death or bankruptcy of a member by sending or delivering it,
in any manner authorised by the articles for the giving of notice to a member,
addressed to them by name, or by the title of representatives of the deceased,
or trustee of the bankrupt or by any like description at the address, if any,
within the British Islands supplied for that purpose by the persons claiming to
be so entitled. Until such an address has been supplied, a notice may be given
in any manner in which it might have been given if the death or bankruptcy had
not occurred.


                                   WINDING UP

125. If the Company is wound up, the liquidator may, with the sanction of an
extraordinary resolution of the Company and any other sanction required by the
Act, divide among the members in specie the whole or any part of the assets of
the Company and may, for that purpose, value any assets and determine how the
division


<PAGE>

                                                                              42


shall be carried out as between the members or different classes of members. The
liquidator may, with the like sanction, vest the whole or any part of the assets
in trustees upon such trusts for the benefit of the members as he with the like
sanction determines, but no member shall be compelled to accept any assets upon
which there is a liability.


                                    INDEMNITY

126. Every Director or other officer of the Company shall be entitled to be
indemnified out of the assets of the Company against all losses or liabilities
(including any such liability as is mentioned in paragraph (c) of the proviso to
Section 151 of the Act) which he may sustain or incur in or about the execution
of the duties of his office or otherwise in relation thereto, and no Director or
other officer shall be liable for any loss, damage or misfortune which may
happen to or be incurred by the Company in the execution of the duties of his
office or in relation thereto. But this Article shall only have effect in so far
as its provisions are not avoided by the said Section.

127. The Company may purchase and maintain indemnity insurance for the benefit
of each Director or other officer of the Company.

(3) In these regulations, unless there is something in the subject of context
inconsistent with such construction:-

                  (a) words importing the plural number shall be deemed to
                  include the singular number and words importing the singular

                                  SHARE CAPITAL

5.       (1) Subject to the provisions of the Act and without prejudice to any
         rights attached to any existing shares, any share may be issued with
         such rights or restrictions as the Company may by ordinary resolution
         determine.

         (2) Subject to the provisions of the Act, shares may be issued in
         fractional denominations to the same extent as whole shares.

6. Subject to the provisions of the Act and the articles, redeemable preference
shares may be issued on such terms and in such manner as may be provided by the
articles.


<PAGE>

                                                                               8


7. The Company may exercise the powers of paying commissions conferred by the
Act. Subject to the provisions of the Act, any such commissions may be satisfied
by the payment of cash or by the allotment of fully or partly paid shares or
partly in one way and partly in the other.

8. Except as required by law, no person shall be recognised by the Company as
holding any share upon any trust and (except as otherwise provided by the
articles or by law) the Company shall not be bound by or recognise any interest
in any share except an absolute right to the entirety thereof in the holder.

9. The shares shall be at the disposal of the Directors, and (save as otherwise
directed by the Company in General Meeting) they may allot or otherwise dispose
of them to such persons at such times and generally on such terms and conditions
as they think proper, subject nevertheless to article 2 and provided that no
shares shall be issued at a discount, except as provided by Section 47 of the
Act.

10. If at any time the share capital is divided into different classes of
shares, the rights attached to any class (unless otherwise provided by the terms
of issue of the shares of that class) may be varied with the consent in writing
of the holders of all of the issued shares of that class, or with the sanction
of an extraordinary resolution passed at a separate general meeting of the
holders of the shares of the class. To every such separate general meeting the
provisions of these regulations relating to general meetings shall in the case
of the number of holders of a particular class of shares being two or more
mutatis mutandis apply, but so that the necessary quorum shall be two persons at
least holding or representing by proxy one-third of the issued shares of the
class, and that any holder of shares of the class present in person or by proxy
may demand a poll. In the case of the number of holders of a particular class of
shares being one, one person holding or representing all the issued shares of
the class shall be a quorum.

                                                                               9


11. The Company may issue share warrants to bearer in respect of any fully
paid-up shares of the Company, stating that the bearer of the warrant is
entitled to the shares therein specified. Such warrants shall be issued upon
such terms and subject to such conditions as may be resolved upon by the
Directors. Subject to the provisions of the Act and of these articles the holder
of a share warrant shall be deemed to be a member of the Company and shall be
entitled to the same rights and privileges as he would have had if his name had
been included in the share register of the Company as the holder of the shares.


                               SHARE CERTIFICATES

12.      (1) Every member, upon becoming the holder of any shares shall be
         entitled

                  (a) without payment, to one certificate for all the shares of
                  each class held by him (and, upon transferring a part of his
                  holding of shares of any class, to a certificate for the
                  balance of such holding); or

                  (b) to several certificates each for one or more of his shares
                  upon payment, for every certificate after the first, of such
                  reasonable sum as the Directors may determine.

         (2) Every certificate shall be sealed with the seal and shall specify
         the number, class and distinguishing numbers (if any) of the shares to
         which it relates and the amount or respective amounts paid up thereon.

         (3) The Company shall not be bound to issue more than one certificate
         for shares held jointly by several persons and delivery of a
         certificate to one joint holder shall be a sufficient delivery to all
         of them.


<PAGE>

                                                                              10


13. If a share certificate is defaced, worn-out, lost or destroyed, it may be
renewed on such terms (if any) as to evidence and indemnity and payment of the
expenses reasonably incurred by the Company in investigating evidence as the
Directors may determine but otherwise free of charge, and (in the case of
defacement or wearing-out) on delivery up of the old certificate.

14. The Company shall have a first and paramount lien on every share for all
moneys (whether presently payable or not) payable at a fixed time or called in
respect of that share. The Directors may at any time declare any share to be
wholly or in part exempt from the provisions of this regulation. The Company's
lien on a share shall extend to any amount payable in respect of it.

15. The Company may sell in such manner as the Directors determine any shares on
which the Company has a lien if a sum in respect of which the lien exists is
presently payable and is not paid within fourteen clear days after notice has
been given to the holder of the share or to the person entitled to it in
consequence of the death or bankruptcy of the holder, demanding payment and
stating that if the notice is not complied with the shares may be sold.

16. To give effect to a sale the Directors may authorise some person to execute
an instrument of transfer of the shares, sold to, or in accordance with the
directions of, the purchaser. The title of the transferee to the shares shall
not be affected by any irregularity in or invalidity of the proceedings in
reference to the sale.

17. The net proceeds of the sale, after payment of the costs, shall be applied
in payment of so much of the sum for which the lien exists as is presently
payable, and any residue shall (upon surrender to the Company for cancellation
of the certificate for the shares sold and subject to a like lien for any moneys
not presently payable as existed upon the shares before the sale) be paid to the
person entitled to the shares at the date of the sale.

                                                                              11


                         CALLS ON SHARES AND FORFEITURE

18. Subject to the terms of allotment, the Directors may make calls upon the
members in respect of any moneys unpaid on their shares (whether in respect of
nominal value or premium) and each member shall (subject to receiving at least
fourteen clear days notice specifying when and where payment is to be made) pay
to the Company as required by the notice the amount called on his shares. A call
may be required to be paid by instalments. A call may, before receipt by the
Company of any sum due thereunder, be revoked in whole or in part and payment of
a call may be postponed in whole or in part. A person upon whom a call is made
shall remain liable for calls made upon him notwithstanding the subsequent
transfer of the shares in respect whereof the call was made.

19. A call shall be deemed to have been made at the time when the resolution of
the Directors authorising the call was passed.

20. The joint holders of a share shall be jointly and severally liable to pay
all calls in respect thereof.

21. If a call remains unpaid after it has become due and payable the person from
whom it is due and payable shall pay interest on the amount unpaid from the day
it became due and payable until it is paid at the rate fixed by the terms of
allotment of the share or in the notice of the call or, if no rate is fixed, at
the rate of (pound)5 per centum per annum but the Directors may waive payment of
the interest wholly or in part.

22. An amount payable in respect of a share on allotment or at any fixed date,
whether in respect of nominal value or premium or as an instalment of a call,
shall be deemed to be a call and if it is not paid the provisions of the
articles shall apply as if that amount had become due and payable by virtue of a
call.


<PAGE>

                                                                              12


23. Subject to the terms of allotment, the Directors may make arrangements on
the issue of shares for a difference between the holders in the amounts and
times of payment of calls on their shares.

24. If a call remains unpaid after it has become due and payable the Directors
may give to the person from whom it is due not less than fourteen clear days'
notice requiring payment of the amount unpaid together with any interest which
may have accrued. The notice shall name the place where payment is to be made
and shall state that if the notice is not complied with the shares in respect of
which the call was made will be liable to be forfeited.

25. If the notice is not complied with any share in respect of which it was
given may, before the payment required by the notice has been made, be forfeited
by a resolution of the Directors and the forfeiture shall include all dividends
or other moneys payable in respect of the forfeited shares and not paid before
the forfeiture.

26. Subject to the provisions of the Act, a forfeited share may be sold,
re-allotted or otherwise disposed of on such terms and in such manner as the
Directors determine either to the person who was before the forfeiture the
holder or to any other person and at any time before sale, re-allotment or other
disposition, the forfeiture may be cancelled on such terms as the Directors
think fit. Where for the purposes of its disposal a forfeited share is to be
transferred to any person the Directors may authorise some person to execute an
instrument of transfer of the share to that person.

27. A person any of whose shares have been forfeited shall cease to be a member
in respect of them and shall surrender to the Company for cancellation the
certificate for the shares forfeited but shall remain liable to the Company for
all moneys which at the date of forfeiture were presently payable by him to the
Company in respect of those shares with interest at the rate at which interest
was payable on those moneys before the forfeiture or, if no interest was so
payable, at the rate of (pound)5 per centum per annum


<PAGE>

                                                                              13


from the date of forfeiture until payment but the Directors may waive payment
wholly or in part or enforce payment without any allowance for the value of the
shares at the time of forfeiture or for any consideration received on their
disposal.

28. A statutory declaration by a Director or the secretary that a share has been
forfeited on a specified date shall be conclusive evidence of the facts stated
in it as against all persons claiming to be entitled to the share and the
declaration shall (subject to the execution of an instrument of transfer if
necessary) constitute a good title to the share and the person to whom the share
is disposed of shall not be bound to see to the application of the
consideration, if any, nor shall his title to the share be affected by any
irregularity in or invalidity of the proceedings in reference to the forfeiture
or disposal of the share.


                               TRANSFER OF SHARES

29. The instrument of transfer of a share may be in any usual form or in any
other form which the Directors may approve and shall be executed by or on behalf
of the transferor and, unless the share is fully paid, by or on behalf of the
transferee.

30. No transfer of any share in the capital of the Company to any person not
already a member of the Company shall be made or registered without the previous
sanction of the Directors, who may without assigning any reason, decline to give
any such sanction. The Directors may also suspend the registration of transfers
during the fourteen days immediately preceding the Ordinary General Meeting in
each year. The Directors may decline to recognise any instrument of transfer
unless accompanied by the certificate of the shares to which it relates, and
such other evidence as the Directors may reasonably require to show the right of
the transferor to make the transfer. The Directors may decline to register a
transfer of any shares on which the Company has a lien. If the Directors refuse
to register a transfer of any share they


<PAGE>

                                                                              14


shall within two months after the date on which the transfer was lodged with the
Company send to the transferee notice of the refusal as required by section 67
of the Act.

31. The Company shall be entitled to retain any instrument of transfer which is
registered, but any instrument of transfer which the Directors refuse to
register shall be returned to the person lodging it when notice of the refusal
is given.


                             TRANSMISSION OF SHARES

32. If a member dies the survivor or survivors where he was a joint holder, and
his personal representatives where he was a sole holder or the only survivor of
joint holders, shall be the only persons recognised by the Company as having any
title to his interest; but nothing herein contained shall release the estate of
a deceased member from any liability in respect of any share which had been
jointly held by him.

33. A person becoming entitled to a share in consequence of the death or
bankruptcy of a member may, upon such evidence being produced as the Directors
may properly require, elect either to become the holder of the share or to have
some person nominated by him registered as the transferee. If he elects to
become the holder he shall give notice to the Company to that effect. If he
elects to have another person registered he shall execute an instrument of
transfer of the share to that person. All articles relating to the transfer of
shares shall apply to the notice or instrument of transfer as if it were an
instrument of transfer executed by the member and the death or bankruptcy of the
member had not occurred.

34. A person becoming entitled to a share in consequence of the death or
bankruptcy of a member shall have the rights to which he would be entitled if he
were the holder of the share, except that he shall not, before being registered
as the holder


<PAGE>

                                                                              15


of the share, be entitled in respect of it to attend or vote at any meeting of
the Company or at any separate meeting of the holders of any class of shares in
the Company.


                           ALTERATION OF SHARE CAPITAL

35. The Company may by ordinary resolution -

                  (a) increase its share capital by new shares of such amount as
                  the resolution prescribes;

                  (b) consolidate and divide all or any or its share capital
                  into shares of larger amount than its existing shares;

                  (c) subject to the provisions of the Act, sub-divide its
                  shares, or any of them, into shares of smaller amount and the
                  resolution may determine that, as between the shares resulting
                  from the sub-division, any of them may have any preference or
                  advantage as compared with the others; and

                  (d) cancel shares which, at the date of the passing of the
                  resolution, have not been taken or agreed to be taken by any
                  person and diminish the amount of its share capital by the
                  amount of the shares so cancelled.

36. Whenever as a result of a consolidation of shares any members would become
entitled to fractions of a share, the Directors may, instead of issuing the
fractions of a share, on behalf of those members, sell the shares representing
the fractions for the best price reasonably obtainable to any person (including,
subject to the provisions of the Act, the Company) and distribute the net
proceeds of sale in due proportion among those members, and the Directors may
authorise some person to execute an instrument of transfer of the shares to, or
in accordance with the directions of, the purchaser. The


<PAGE>

                                                                              16


transferee shall not be bound to see to the application of the purchase money
nor shall his title to the shares be affected by any irregularity in or
invalidity of the proceedings in reference to the sale.

37. Subject to the provisions of the Act, the Company may by special resolution
reduce its share capital, any capital redemption reserve and any share premium
account in any way.


                         CONVERSION OF SHARES INTO STOCK

38. The Company may by ordinary resolution convert any paid-up shares into stock
and reconvert any stock into paid-up shares of any denomination.

39. The holders of stock may transfer the same, or any part thereof, in the same
manner, and subject to the same regulations, as, and subject to which, the
shares from which the stock arose might previously to conversion have been
transferred, or as near thereto as circumstances admit; but the Directors may
from time to time fix the minimum amount of stock transferable and restrict or
forbid the transfer of fractions of that minimum, but the minimum shall not
exceed the nominal amount of the shares from which the stock arose.

40. The holders of stock shall, according to the amount of the stock held by
them, have the same rights, privileges and advantages as regards dividends,
voting at meetings of the Company and other matters as if they held the shares
from which the stock arose, but no such privilege or advantage (except
participation in the dividends and profits of the Company) shall be conferred by
any such aliquot part of stock as would not, if existing in shares, have
conferred that privilege or advantage.


<PAGE>

                                                                              17


41. Such of the regulations of the Company as are applicable to paid-up shares
shall apply to stock and the words "shares" and "shareholder" therein shall
include "stock" and "stockholder".


                         REDEMPTION OF PREFERENCE SHARES

42. Subject to the provisions of the Act, the redemption of redeemable
preference shares shall be effected on such terms and in such manner, as may be
provided by the articles.


                                GENERAL MEETINGS

43. All general meetings other than annual general meetings shall be called
extraordinary general meetings.

44. The Directors may call general meetings, and on the requisition of a member
pursuant to the provisions of the Act, shall forthwith proceed to convene an
extraordinary general meeting for a date not later than eight weeks after

                  (b) In the case of any other meeting by a majority in number

                  in nominal value of the shares giving that right.

The notice shall specify the time and place of the meeting and the general

Subject to the provisions of the articles and to any restrictions imposed on any
shares, the notice shall be given to all the members, to all persons entitled to

Directors and auditors.

46. The accidental omission to give notice of a meeting to or the non-receipt of
notice of a meeting by any person entitled to receive notice shall not
invalidate the proceedings at that meeting.


                         PROCEEDINGS AT GENERAL MEETINGS

47. No business shall be transacted at any meeting unless a quorum is present.
Two persons entitled to vote upon the business to be transacted, each being a
member or a proxy for a member or a duly authorised representative of a
corporation which is a member, shall be a quorum. When the Company has a single
member, the member


<PAGE>

                                                                              19


or the proxy for the member or a duly authorised representative of the
corporation which is the member, shall be a quorum.

48. If such a quorum is not present within half an hour from the time appointed
for the meeting or if during a meeting such a quorum ceases to be present, the
meeting shall stand adjourned to the same day in the next week at the same time
and place or to such time and place as the Directors may determine.

49. The Chairman, if any, of the Board of Directors or in his absence some other
Director nominated by the Directors shall preside as Chairman of the meeting,
but if neither the Chairman nor such other Director (if any) be present within
fifteen minutes after the time appointed for holding the meeting and willing to
act, the Directors present shall elect one of their number to be Chairman and if
there is only one Director present and willing to act, he shall be Chairman.

50. If no Director is willing to act as Chairman, or if no Director is present
within fifteen minutes after the time appointed for holding the meeting, the
members present and entitled to vote shall choose one of their number to be
Chairman.

51. A Director shall, notwithstanding that he is not a member, be entitled to
attend and speak at any general meeting and at any separate meeting of the
holders of any class of shares in the Company.

52. The Chairman may, with the consent of a meeting at which a quorum is present
(and shall if so directed by the meeting), adjourn the meeting from time to time
and from place to place, but no business shall be transacted at an adjourned
meeting other than business which might properly have been transacted at the
meeting had the adjournment not taken place. When a meeting is adjourned for
fourteen days or more, at least seven clear days' notice shall be given
specifying the time and place of the

<PAGE>

                                                                              20


adjourned meeting and the general nature of the business to be transacted.
Otherwise it shall not be necessary to give any such notice.

53. A resolution put to the vote of a meeting shall be decided on a show of
hands unless before, or on the declaration of the result of, the show of hands a
poll is duly demanded. Subject to the provisions of the Act, a poll may be
demanded -

         (a) by the Chairman; or

                  (b) by at least two members having the right to vote at the
                  meeting; or

                  (c) by a member or members representing no less than one-tenth
                  of the total voting rights of all the members having the right
                  to vote at the meeting; or

                  (d) by a member or members holding shares conferring a right
                  to vote at the meeting being shares on which an aggregate sum
                  has been paid up equal to not less than one-tenth of the total
                  sum paid up on all the shares conferring that right;

and a demand by a person as proxy for a member shall be the same as a demand by
the member.

54. Unless a poll is duly demanded a declaration by the Chairman that a
resolution has been carried or carried unanimously, or by a particular majority,
or lost, or not carried by a particular majority and an entry to that effect in
the minutes of the meeting shall be conclusive evidence of the fact without
proof of the number or proportion of the votes recorded in favour of or against
the resolution.


<PAGE>

                                                                              21


55. The demand for a poll may, before the poll is taken, be withdrawn but only
with the consent of the Chairman and a demand so withdrawn shall not be taken to
have invalidated the result of a show of hands declared before the demand was
made.

56. A poll shall be taken as the Chairman directs and he may appoint scrutineers
(who need not be members) and fix a time and place for declaring the result of
the poll. The result of the poll shall be deemed to be the resolution of the
meeting at which the poll was demanded.

57. In the case of an equality of votes, whether on a show of hands or on a
poll, the Chairman shall be entitled to a casting vote in addition to any other
vote he may have.

58. A poll demanded on the election of a Chairman or on a question of
adjournment shall be taken forthwith. A poll demanded on any other question
shall be taken either forthwith or at such time and place as the Chairman
directs not being more than thirty days after the poll is demanded. The demand
for a poll shall not prevent the continuance of a meeting for the transaction of
any business other than the question on which the poll was demanded. If a poll
is demanded before the declaration of the result of a show of hands and the
demand is duly withdrawn, the meeting shall continue as if the demand had not
been made.

59. No notice need be given of a poll not taken forthwith if the time and place
at which it is to be taken are announced at the meeting at which it is demanded.
In any other case at least seven clear days notice shall be given specifying the
time and place at which the poll is to be taken.

60. A resolution in writing executed by or on behalf of each member who would
have been entitled to vote upon it if it had been proposed at a general meeting
at which he was present shall be as effectual as if it had been passed at a
general meeting duly convened and held and may consist of several instruments in
the like form each


<PAGE>

                                                                              22


executed by or on behalf of one or more members, provided the provisions of
Section 118B of the Act are complied with and that such resolution is received
by the Company at its registered office within seven days of the date of its
execution in terms hereof.





                                VOTES OF MEMBERS

61. Subject to any rights or restrictions attached to any shares, on a show of
hands every member who (being an individual) is present in person or by proxy or
(being a corporation) is present by a duly authorised representative, not being
himself a member, shall have one vote and on a poll every member entitled to
vote shall have one vote for every share of which he is the holder.

62. In the case of joint holders the vote of the senior who tenders a vote,
whether in person or by proxy, shall be accepted to the exclusion of the votes
of the other joint holders; and seniority shall be determined by the order in
which the names of the holders stand in the register of members.

63. A member in respect of whom an order has been made by any court having
jurisdiction (whether in the Isle of Man or elsewhere) in matters concerning
mental disorder may vote, whether on a show of hands or on a poll, by his
receiver, curator bonis or other person authorised in that behalf appointed by
that court, and any such receiver, curator bonis or other person may, on a poll,
vote by proxy. Evidence to the satisfaction of the Directors of the authority of
the person claiming to exercise the right to vote shall be deposited at the
office, or at such other place as is specified in accordance with the articles
for the deposit of instruments of proxy, not less than 48 hours before the time
appointed for holding the meeting or adjourned meeting at which


<PAGE>

                                                                              23


the right to vote is to be exercised and in default the right to vote shall not
be exercisable.

64. No member shall vote at any general meeting or at any separate meeting of
the holders of any class of shares in the Company, either in person or by proxy,
in respect of any share held by him unless all moneys presently payable by him
in respect of that share have been paid.

65. No objections shall be raised to the qualification of any voter except at
the meeting or adjourned meeting at which the vote objected to is tendered, and
every vote not disallowed at the meeting shall be valid. Any objection made in
due time shall be referred to the Chairman whose decision shall be final and
conclusive.

66. On a poll votes may be given either personally or by proxy. A member may
appoint more than one proxy to attend on the same occasion.

67. An instrument appointing a proxy shall be in writing, executed by or on
behalf of the appointor and shall be in the following form (or in a form as near
thereto as circumstances allow or in any other form which is usual or which the
Directors may approve) -

and an instrument of proxy which is not deposited or delivered in a manner so
permitted shall be invalid.

70. A vote given or poll demanded by proxy or by the duly authorised
representative of a corporation shall be valid notwithstanding the previous
determination of the authority of the person voting or demanding a poll unless

other place at which the instrument of proxy was duly deposited before the
commencement of the meeting or adjourned meeting at which the vote is given or

Director, or any other person approved by resolution of the Directors and
willing to act, to be an alternate Director and may remove from office an
alternate Director so appointed by him.

78. Subject to the provisions of the Act, the memorandum and the articles and to
any directions given by special resolution the business of the Company shall be
managed by the Directors who may exercise all the powers of the Company. No
alteration of the memorandum or articles and no such direction shall invalidate
any prior act of the Directors which would have been valid if that alteration
had not been made or that direction had not been given. The powers given by this
regulation shall not be limited by any special power given to the Directors by
the articles and a meeting of Directors at which a quorum is present may
exercise all powers exercisable by the Directors.

of the members in General Meeting, such sum or sums of money for the purposes of
the Company's business as they may think fit and may secure the repayment of or
raise any such sum or sums as aforesaid in such manner and upon such terms and
conditions and in all other respects as they may think fit, and in particular by
mortgages, deeds of bond and security, or other charges upon the whole or any
part of the property and assets of the Company, present or future, including its
uncalled or unissued capital, or by the issue at such price as they may think
fit, of bonds or debentures or debenture stock of the Company, either charged
upon the whole or any part of the property and assets of the Company, or not so

person or persons as consideration for the purchase of any goodwill, business or
property purchased by the Company.

80. The Directors may, by power of attorney or otherwise, appoint any person to

or to the exclusion of their own powers and may be revoked or altered. Subject
to any such conditions, the

82. The Company may from time to time in general meeting increase or reduce the
number of Directors. The Company may by special resolution remove any Director
or by ordinary resolution appoint any person to be a Director.

83. No person other than a first Director shall be appointed a Director in
general meeting unless at least seven days' and not more than fourteen days'

                  a party to any transaction or arrangement with, or otherwise
                  interested in, any body corporate promoted by the Company or
                  in which the Company is otherwise interested; and

                  (c) shall not, by reason of his office, be accountable to the
                  Company for any benefit which he derives from any such office
                  or employment or


<PAGE>

                                                                              32


                  from any such transaction or arrangement or from any interest
                  in any such body corporate and no such transaction or
                  arrangement shall be liable to be avoided on the ground of any
                  such interest or benefit.

91. For the purposes of the foregoing article -

                  (a) a general notice given to the Directors that a Director is
                  to be regarded as having an interest of the nature and extent
                  specified in the notice in any transaction or arrangement in
                  which a specified person or class of persons is interested
                  shall be deemed to be a disclosure that the Director has an
                  interest in any such transaction of the nature and extent so
                  specified; and

                  (b) an interest of which a Director has no knowledge and of
                  which it is unreasonable to expect him to have knowledge shall
                  not be treated as an interest of his.

92. Subject to article 90 hereof and the Act if the Company is a single member
company and having one member it enters into a contract with the sole member
otherwise than in the ordinary course of the Company's business and the sole
member is also a director of the Company, the Company should, unless the
contract is in writing, ensure that the terms of the contract are either set out
in a written memorandum or are recorded in the minutes of the first meeting of
the directors of the Company following the making of the contract.


                       DIRECTORS' GRATUITIES AND PENSIONS

93. Subject to the provisions of the Act, the Directors may provide benefits,
whether by the payment of gratuities or pensions or by insurance or otherwise,
for any Director


<PAGE>

                                                                              33


who has held but no longer holds any executive office or employment with the
Company or with any body corporate which is or has been a subsidiary of the
Company or a predecessor of the Company or of any such subsidiary and for any
member of his family (including a spouse and a former spouse) or any person who
is or was dependent on him, and may (as well before as after he ceases to hold
such office or employment) contribute to any fund and pay premiums for the
purchase or provision of any such benefit.


                            PROCEEDINGS OF DIRECTORS

94. Subject to the provisions of the articles, the Directors may regulate their
proceedings as they think fit. A Director may, and the secretary at the request
of a Director shall, call a meeting of the Directors. Questions arising at a
meeting shall be decided by a majority of votes. In the case of an equality of
votes, the Chairman shall have a second or casting vote. A Director who is also
an alternate Director shall be entitled in the absence of his appointor to a
separate vote on behalf of his appointor in addition to his own vote.

95. The quorum for the transaction of the business of the Directors may be fixed
by the Directors and unless so fixed at any other number shall be two. A person
who holds office only as an alternate Director shall, if his appointor is not
present, be counted in the quorum.

96. The continuing Directors or a sole continuing Director may act
notwithstanding any vacancies in their number, but, if the number of Directors
is less than the number fixed as the quorum, the continuing Directors or
Director may act only for the purpose of filling vacancies or of calling a
general meeting.

                                                                              34


97. The Directors may appoint one of their number to be the Chairman of the
Board of Directors and may at any time remove him from that office. Unless he is
unwilling to do so, the Director so appointed shall preside at every meeting of
Directors at which he is present. But if there is no Director holding that
office, or if the Director holding it is unwilling to preside or is not present
within five minutes after the time appointed for the meeting, the Directors
present may appoint one of their number to be Chairman of the meeting.

98. All acts done by a meeting of Directors, or of a committee of Directors, or
by a person acting as a Director shall, notwithstanding that it be afterwards
discovered that there was a defect in the appointment of any Director or that
any of them were disqualified from holding office, or had vacated office, or
were not entitled to vote, be valid as if every such person had been duly
appointed and was qualified and had continued to be a Director and had been
entitled to vote.

99. A resolution in writing signed by all the Directors entitled to receive
notice of a meeting of Directors or of a committee of Directors shall be as
valid and effectual as if it had been passed at a meeting of Directors or (as
the case may be) a committee of Directors duly convened and held and may consist
of several documents in the like form each signed by one or more Directors, but
a resolution signed by an alternate need not also be signed by his appointor
and, if it is signed by a Director who has appointed an alternate Director, it
need not be signed by the alternate Director in that capacity.

100. Save as otherwise provided by the articles, a Director shall not vote at a
meeting of Directors or of a committee of Directors on any resolution concerning
a matter in which he has, directly or indirectly, an interest or duty which is
material and which conflicts or may conflict with the interest of the Company
unless he has declared the nature of his interest in the manner required by
Section 148 of the Act.

101. A Director shall not be counted in the quorum present at a meeting in
relation to a resolution on which he is not entitled to vote.

102. The Company may by ordinary resolution suspend or relax to any extent,
either generally or in respect of any particular matter, any provision of the
articles prohibiting a Director from voting at a meeting of Directors or of a
committee of Directors.

103. If a question arises at a meeting of Directors or of a committee of
Directors as to the right of a Director to vote, the question may, before the
conclusion of the meeting, be referred to the Chairman of the meeting and his
ruling in relation to any Director other than himself shall be final and
conclusive.

104. Any Director or member of a committee of the Directors may participate in a
meeting of the Directors or such committee by means of telephonic or similar
communications whereby all persons participating in the meeting can hear each
other and participation in a meeting in this manner shall be deemed to
constitute presence in person at such meeting. The location of such a telephonic
meeting shall be deemed to be the place at which the Chairman of the meeting was
located at the time of the meeting.




                             MANAGEMENT AND CONTROL

105. The management and control of the business of the Company shall be in and
from the Isle of Man or in and from such other place as the Directors shall
decide.

                                                                              36


                                    SECRETARY

106. Subject to the provisions of the Act, the secretary shall be appointed by
the Directors for such term, at such remuneration and upon such conditions as
they may think fit; and any secretary so appointed may be removed by them.



                                     MINUTES

107. The Directors shall cause Minutes to be made in books kept for the purpose
- -

                  (a) of all appointments of officers made by the Directors; and

                  (b) of all proceedings at meetings of the Company, of the
                  holders of any class of shares in the Company and of the
                  Directors, and of committees of Directors, including the names
                  of the Directors present at such meeting.


                                    THE SEAL

108. The Company shall have a Company Seal.

109. The seal shall only be used by the authority of the Directors or of a
committee of Directors authorised by the Directors. The Directors may determine
who shall sign any instrument to which the seal is affixed and unless otherwise
so determined it shall be signed by a Director and by the secretary or by a
second Director.

                                                                              37


                                    DIVIDENDS

110. Subject to the provisions of the Act, the Company may by ordinary
resolution declare dividends in accordance with the respective rights of the
members, but no dividend shall exceed the amount recommended by the Directors.

111. Subject to the provisions of the Act, the Directors may pay interim
dividends if it appears to them that they are justified by the profits of the
Company available for distribution. If the share capital is divided into
different classes, the Directors may pay interim dividends on shares which
confer deferred or non-preferred rights with regard to dividend as well as on
shares which confer preferential rights with regard to dividend, but no interim
dividend shall be paid on shares carrying deferred or non-preferential rights
if, at the time of payment, any preferential dividend is in arrear. The
Directors may also pay at intervals settled by them any dividend payable at a
fixed rate if it appears to them that the profits available for distribution
justify the payment. Provided the Directors act in good faith they shall not
incur any liability to the holders of shares conferring preferred rights for any
loss they may suffer by the lawful payment of an interim dividend on any shares
having deferred or non-preferred rights.

112. Except as otherwise provided by the rights attached to shares, all
dividends shall be declared and paid according to the amounts paid up on the
shares on which the dividend is paid. All dividends shall be apportioned and
paid proportionately to the amounts paid up on the shares during any portion or
portions of the period in respect of which the dividend is paid; but, if any
share is issued on terms providing that it shall rank for dividend as from a
particular date, that share shall rank for dividend accordingly.

113. A general meeting declaring a dividend may, upon the recommendation of the
Directors, direct that it shall be satisfied wholly or partly by the
distribution of assets


<PAGE>

                                                                              38


and where any difficulty arises in regard to the distribution, the Directors may
settle the same and in particular may issue fractional certificates and fix the
value for distribution of any assets and may determine that cash shall be paid
to any member upon the footing of the value so fixed in order to adjust the
rights of members and may vest any assets in trustees.

114. Any dividend or other moneys payable in respect of a share may be paid by
cheque sent by post to the registered address of the person entitled or, if two
or more persons are the holders of the share or are jointly entitled to it by
reason of the death or bankruptcy of the holder, to the registered address of
that one of those persons who is first named in the register of members or to
such person and to such address as the person or persons entitled may in writing
direct. Every cheque shall be made payable to the order of the person or persons
entitled or to such other person as the person or persons entitled may in
writing direct and payment of the cheque shall be a good discharge to the
Company. Any joint holder or other person jointly entitled to a share as
aforesaid may give receipts for any dividend or other moneys payable in respect
of the share.

115. No dividend or other moneys payable in respect of a share shall bear
interest against the Company unless otherwise provided by the rights attached to
the share.

116. Any dividend which has remained unclaimed for twelve years from the date
when it became due for payment shall, if the Directors so resolve, be forfeited
and cease to remain owing by the Company.


                                    ACCOUNTS

117.              (a) No member shall (as such) have any right of inspecting any
                  accounting records or other book or document of the Company
                  except as


<PAGE>

                                                                              39


                  conferred by statute or authorised by the Directors or by
                  ordinary resolution of the Company.

                  (b) The Company shall prepare such accounts as may be required
                  by the Act and the laws of the Isle of Man.

                  (c) Subject to the Act and the laws of the Isle of Man the
                  Company may elect to dispense with compliance with the
                  requirements of the Act which relate to the audit of the
                  accounts of the Company.


                            CAPITALISATION OF PROFITS

118. The Directors may with the authority of an ordinary resolution of the
Company -

                  (a) subject as hereinafter provided, resolve to capitalise any
                  undivided profits of the Company not required for paying any
                  preferential dividend (whether or not they are available for
                  distribution) or any sum standing to the credit of the
                  Company's share premium account or capital redemption reserve;

                  (b) appropriate the sum resolved to be capitalised to the
                  members who would have been entitled to it if it were
                  distributed by way of dividend and in the same proportions and
                  apply such sum on their behalf either in or towards paying up
                  the amounts, if any, for the time being unpaid on any shares
                  held by them respectively, or in paying up in full unissued
                  shares or debentures of the Company of a nominal amount, equal
                  to that sum, and allot the shares or debentures credited as
                  fully paid to those members, or as they may direct, in those
                  proportions, or partly in one way and partly in the other: but
                  the share premium account, the capital


<PAGE>

                                                                              40


                  redemption reserve and any profits which are not available for
                  distribution may, for the purposes of this regulation, only be
                  applied in paying up unissued shares to be allotted to members
                  credited as fully paid;

                  (c) make such provision by the issue of fractional
                  certificates or by payment in cash or otherwise as they
                  determine in the case of shares or debentures becoming
                  distributable under this regulation in fractions; and

                  (d) authorise any person to enter on behalf of all the members
                  concerned into an agreement with the Company providing for the
                  allotment to them respectively, credited as fully paid, of any
                  shares or debentures to which they are entitled upon such
                  capitalisation, any agreement made under such authority being
                  binding on all such members.


                                     NOTICES

119. Any notice to be given to or by any person pursuant to the articles shall
be in writing except that a notice calling a meeting of the Directors need not
be in writing.

120. The Company may give any notice to a member either personally or by sending
it by post in a prepaid envelope addressed to the member at his registered
address or by leaving it at that address. In the case of joint holders of a
share, all notices shall be given to the joint holder whose name stands first in
the register of members in respect of the joint holding and notice so given
shall be sufficient notice to all the joint holders. A member whose registered
address is not within the British Islands and who gives to the Company an
address within the British Islands at which notices may be given to him shall be
entitled to have notices given to him at that address, but otherwise no such
member shall be entitled to receive any notice from the Company.

                                                                              41


121. A member present, either in person or by proxy, at any meeting of the
Company or of the holders of any class of shares in the Company shall be deemed
to have received notice of the meeting and, where requisite, of the purposes for
which it was called.

122. Every person who becomes entitled to a share shall be bound by any notice
in respect of that share which, before his name is entered in the register of
members, has been duly given to a person from whom he derives his title.

123. Proof that an envelope containing a notice was properly addressed, prepaid
and posted shall be conclusive evidence that the notice was given. A notice
shall be deemed to be given at the expiration of 48 hours after the envelope
containing it was posted.

124. A notice may be given by the Company to the persons entitled to a share in
consequence of the death or bankruptcy of a member by sending or delivering it,
in any manner authorised by the articles for the giving of notice to a member,
addressed to them by name, or by the title of representatives of the deceased,
or trustee of the bankrupt or by any like description at the address, if any,
within the British Islands supplied for that purpose by the persons claiming to
be so entitled. Until such an address has been supplied, a notice may be given
in any manner in which it might have been given if the death or bankruptcy had
not occurred.


                                   WINDING UP

125. If the Company is wound up, the liquidator may, with the sanction of an
extraordinary resolution of the Company and any other sanction required by the
Act, divide among the members in specie the whole or any part of the assets of
the Company and may, for that purpose, value any assets and determine how the
division


<PAGE>

                                                                              42


shall be carried out as between the members or different classes of members. The
liquidator may, with the like sanction, vest the whole or any part of the assets
in trustees upon such trusts for the benefit of the members as he with the like
sanction determines, but no member shall be compelled to accept any assets upon
which there is a liability.


                                    INDEMNITY

126. Every Director or other officer of the Company shall be entitled to be
indemnified out of the assets of the Company against all losses or liabilities
(including any such liability as is mentioned in paragraph (c) of the proviso to
Section 151 of the Act) which he may sustain or incur in or about the execution
of the duties of his office or otherwise in relation thereto, and no Director or
other officer shall be liable for any loss, damage or misfortune which may
happen to or be incurred by the Company in the execution of the duties of his
office or in relation thereto. But this Article shall only have effect in so far
as its provisions are not avoided by the said Section.

127. The Company may purchase and maintain indemnity insurance for the benefit
of each Director or other officer of the Company.

                                 THE SECURITIES

                  SECTION 2.01. FORM AND DATING. Provisions relating to the
Initial Securities, the Private Exchange Securities and the Exchange Securities
are set forth in the Rule 144A/Regulation S Appendix attached hereto (the
"Appendix") which is hereby incorporated in and expressly made part of this
Indenture. The Initial Securities and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit 1 to the Appendix
which is hereby incorporated in and expressly made a part of this Indenture. The
Exchange Securities, the Private Exchange Securities and the Trustee's
certificate of authentication shall be substantially in the form of Exhibit A,
which is hereby incorporated in and expressly made a part of this Indenture. The
Securities may have notations, legends or endorsements required by law, stock
exchange rule, agreements to which the Company is subject, if any, or usage
(provided that any such notation, legend or endorsement is in a form acceptable
to the Company). Each Security shall be dated the date of its authentication.
The terms of the Securities set forth in the Appendix and Exhibit A are part of
the terms of this Indenture.

                  SECTION 2.02.  EXECUTION AND AUTHENTICATION.  Two
Officers shall sign the Securities for the Company by manual
or facsimile signature.

                  If an Officer whose signature is on a Security no longer holds
that office at the time the Trustee authenti cates the Security, the Security
shall be valid neverthe less.

                  A Security shall not be valid until an authorized signatory of
the Trustee manually signs the certificate of authentication on the Security.
The signature shall be con clusive evidence that the Security has been
authenticated under this Indenture.

                  The Trustee shall authenticate and deliver Securities for
original issue upon a written order of the Company signed by two Officers or by
an Officer and either an Assistant Treasurer or an Assistant Secretary of the
Company. Such order shall specify the amount of the Securities to be
authenticated and the date on which the original issue of Securities is to be
authenticated. The aggregate principal amount of Securities outstanding at any

                                                                              26

time may not exceed that amount except as provided in
Section 2.06.

                  The Trustee may appoint an authenticating agent reasonably
acceptable to the Company to authenticate the Securities. Unless limited by the
terms of such appoint ment, an authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authen tication by such agent. An
authenticating agent has the same rights as any Registrar, Paying Agent or agent
for service of notices and demands.

                  SECTION 2.03. REGISTRAR AND PAYING AGENT. The Company shall
maintain an office or agency where Securities may be presented for registration
of transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent"). The Registrar
shall keep a register of the Secur ities and of their transfer and exchange. The
Company may have one or more co-registrars and one or more additional paying
agents. The term "Paying Agent" includes any addi tional paying agent.

                  The Company shall enter into an appropriate agency agreement
with any Registrar, Paying Agent or co-registrar not a party to this Indenture,
which shall incorporate the terms of the TIA. The agreement shall implement the
provi sions of this Indenture that relate to such agent. The Company shall
notify the Trustee of the name and address of any such agent. If the Company
fails to maintain a Regis trar or Paying Agent or to notify the Trustee as
provided in the previous sentence, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.07. The
Company or any of its domestically incorporated Wholly Owned Subsidiaries may
act as Paying Agent, Registrar, co-registrar or transfer agent.

                  The Company initially appoints the Trustee as Registrar and
Paying Agent in connection with the Securi ties.

                  SECTION 2.04. PAYING AGENT TO HOLD MONEY IN TRUST. Prior to
each due date of the principal and interest on any Security, the Company shall
deposit with the Paying Agent a sum sufficient to pay such principal and
interest when so becoming due. The Company shall require each Paying Agent
(other than the Trustee) to agree in writing that the Paying Agent shall hold in
trust for the benefit of Securityholders or the Trustee all money held by the
Paying

                                                                              27

Agent for the payment of principal of or interest on the Securities and shall
notify the Trustee of any default by the Company in making any such payment. If
the Company or a Subsidiary acts as Paying Agent, it shall segregate the money
held by it as Paying Agent and hold it as a separate trust fund. The Company at
any time may require a Paying Agent to pay all money held by it to the Trustee
and to account for any funds disbursed by the Paying Agent. Upon complying with
this Section, the Paying Agent shall have no further liability for the money
delivered to the Trustee.

                  SECTION 2.05. SECURITYHOLDER LISTS. The Trustee shall preserve
in as current a form as is reasonably prac ticable the most recent list
available to it of the names and addresses of Securityholders. If the Trustee is
not the Registrar, the Company shall furnish to the Trustee, in writing at least
five Business Days before each interest payment date and at such other times as
the Trustee may request in writing, a list in such form and as of such date as
the Trustee may reasonably require of the names and addresses of
Securityholders.

                  SECTION 2.06. REPLACEMENT SECURITIES. If a mutilated Security
is surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies
any other reasonable requirements of the Trustee. If required by the Trustee or
the Company, such Holder shall furnish an indemnity bond sufficient in the
judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent, the Registrar and any co-registrar from any loss which any of them
may suffer if a Security is replaced. The Company and the Trustee may charge the
Holder for their expenses in replacing a Security.

                  Every replacement Security is an additional obligation of the
Company.

                  SECTION 2.07. OUTSTANDING SECURITIES. Securities outstanding
at any time are all Securities authenticated by the Trustee except for those
canceled by it, those delivered to it for cancelation and those described in
this Section as not outstanding. A Security does not cease to be outstand ing
because the Company or an Affiliate of the Company holds the Security.

                                                                              28

                  If a Security is replaced pursuant to Section 2.06, it ceases
to be outstanding unless the Trustee and the Company receive proof satisfactory
to them that the replaced Security is held by a bona fide purchaser.

                  If the Paying Agent segregates and holds in trust, in
accordance with this Indenture, on a redemption date or maturity date money
sufficient to pay all principal and interest payable on that date with respect
to the Securities (or portions thereof) to be redeemed or maturing, as the case
may be, then on and after that date such Securities (or portions thereof) cease
to be outstanding and interest on them ceases to accrue.

                  SECTION 2.08. TEMPORARY SECURITIES. Until definitive
Securities are ready for delivery, the Company may prepare and the Trustee shall
authenticate temporary Securities. Temporary Securities shall be substantially
in the form of definitive Securities but may have variations that the Company
considers appropriate for temporary Securities. Without unreasonable delay, the
Company shall prepare and the Trustee shall authenticate definitive Securities
and deliver them in exchange for temporary Securities.

                  SECTION 2.09. CANCELATION. The Company at any time may deliver
Securities to the Trustee for cancelation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel and
destroy (subject to the record reten tion requirements of the Exchange Act) all
Securities surrendered for registration of transfer, exchange, payment or
cancelation and deliver a certificate of such destruction to the Company unless
the Company directs the Trustee to deliver canceled Securities to the Company.
The Company may not issue new Securities to replace Securities it has redeemed,
paid or delivered to the Trustee for cancelation.

                  SECTION 2.10. DEFAULTED INTEREST. If the Company defaults in a
payment of interest on the Securities, the Company shall pay defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful
manner. The Company may pay the defaulted interest to the persons who are
Securityholders on a subsequent special record date. The Company shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail to each
Securityholder a notice that states the special record date,

                                                                              29

the payment date and the amount of defaulted interest to be
paid.

                  SECTION 2.11. CUSIP NUMBERS. The Company in issuing the
Securities 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, HOWEVER, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers.


                                    ARTICLE 3

                                   REDEMPTION

                  SECTION 3.01. NOTICES TO TRUSTEE. If the Company elects to
redeem Securities pursuant to paragraph 5 of the Securities or is required to
redeem Securities pursuant to paragraph 6 of the Securities, it shall notify the
Trustee in writing of the redemption date, the principal amount of Securities to
be redeemed and the paragraph of the Securities pursuant to which the redemption
will occur.

                  If the Company is required to redeem Securities pursuant to
paragraph 6 of the Securities, it may reduce the principal amount of Securities
required to be redeemed to the extent it is permitted a credit by the terms of
the Securities and it notifies the Trustee of the amount of the credit and the
basis for it. If the reduction is based on a credit for redeemed or canceled
Securities that the Company has not previously delivered to the Trustee for
cancelation, it shall deliver such Securities with the notice.

                  The Company shall give each notice to the Trustee provided for
in this Section at least 60 days before the redemption date unless the Trustee
consents to a shorter period. Such notice shall be accompanied by an Officers'
Certificate and an Opinion of Counsel from the Company to the effect that such
redemption will comply with the condi tions herein.

                  SECTION 3.02. SELECTION OF SECURITIES TO BE REDEEMED. If fewer
than all the Securities are to be redeemed, the Trustee shall select the
Securities to be redeemed pro rata or by lot or by a method that complies

with applicable legal and securities exchange requirements, if any, and that the
Trustee in its sole discretion shall deem to be fair and appropriate and in
accordance with methods generally used at the time of selection by fiduciaries
in similar circumstances. The Trustee shall make the selection from outstanding
Securities not previously called for redemption. The Trustee may select for
redemption portions of the principal of Securities that have denominations
larger than $1,000. Securities and portions of them the Trustee selects shall be
in amounts of $1,000 or a whole multiple of $1,000. Provisions of this Indenture
that apply to Securities called for redemption also apply to portions of
Securities called for redemption. The Trustee shall notify the Company promptly
of the Securities or portions of Securities to be redeemed.

                  SECTION 3.03. NOTICE OF REDEMPTION. At least 30 days but not
more than 60 days before a date for redemp tion of Securities, the Company shall
mail a notice of redemption by first-class mail to each Holder of Securities to

         redemption payment, interest on Securities (or portion thereof) called
         for redemption ceases to accrue on and after the redemption date;

                  (7) the paragraph of the Securities pursuant to
         which the Securities called for redemption are being

redemption in the Company's name and at the Company's expense. In such event,
the Company shall provide the Trustee with the information required by this
Section.

redemption is mailed, Securities called for redemption become due and payable on
the redemption date and at the redemption price stated in the notice. Upon
surren der to the Paying Agent, such Securities shall be paid at the redemption
price stated in the notice, plus accrued interest to the redemption date.
Failure to give notice or any defect in the notice to any Holder shall not
affect the validity of the notice to any other Holder.

                  SECTION 3.05. DEPOSIT OF REDEMPTION PRICE. Prior to the

Security that is redeemed in part, the Company shall execute and the Trustee

         such Holder (or between a fiduciary, settlor, beneficiary, member or
         shareholder of, or possessor of a power over, such Holder, if such
         Holder is an estate, trust, partnership or corporation) and the Isle of

         Holder (or such fiduciary, settlor, beneficiary, member, shareholder or
         possessor) being or having been a national, domiciliary or resident of

         (2) any estate, inheritance, gift, sale, transfer, personal property of
similar tax, assessment or other governmental charge;

         (3) any tax, assessment or other governmental charge that is imposed or
withheld by reason of the failure of the Holder or beneficial owner of a
Security to comply with a request of the Company or any of the Guarantors, as
the case may be, addressed to the Holder (a) to provide reasonable information
concerning the nationality, residence or identity of the Holder or such
beneficial owner or (b) to make any reasonable declaration or other similar
claim or satisfy any reasonable information or reporting requirement, which, in
the case of (a) or (b), is required or imposed by a statute, treaty, regulation
or administrative practice of the taxing jurisdiction as a precondition to
exemption from all or part of such tax, assessment or governmental charge; or

         (4) any combination of clauses (1), (2) and (3);

principal of or any premium or interest on any such Security, or payment
pursuant to the Guarantees, to any Holder (including a fiduciary or partnership)

Additional Amounts had it been the Holder of the Security. The Company or the
relevant Guarantors, as the case may be, will also (i) make such withholding or
deduction and (ii) remit the full amount deducted or withheld to the relevant
authority in accordance with applicable law. The Company or the relevant
Guarantors, as the case may be, will furnish to Holders of Securities that are
outstanding on the date of the withholding, or deduction for or on account of
Taxes, within 30 days after the date of the payment of any Taxes due pursuant to
applicable law, certified copies of tax receipts evidencing such payment by the
Company or the relevant Guarantors, as the case may be.

Guarantees, excluding such taxes, charges or similar levies imposed by any

the enforcement of the Securities or the Guarantees or an other such document or
instrument following the occurrence of any Event of Default), and the Company

by such Holders.

Company an Officers' Certificate stating that in the course of the performance

                  The foregoing will constitute Events of Default whatever the

or is effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or
governmental body.

                  The term "Bankruptcy Law" means Title 11, UNITED STATES CODE,
or any similar Federal or state law for the relief of debtors. The term
"Custodian" means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law.

                  A Default under clauses (4), (5) or (9) is not an Event of
Default until the Trustee or the holders of at least 25% in principal amount of
the outstanding Securities notify the Company of the Default and the Company
does not cure such Default within the time specified after receipt of such
notice. Such notice must specify the Default, demand that it be remedied and
state that such notice is a "Notice of Default".

                  The Company shall deliver to the Trustee, within 30 days after
the occurrence thereof, written notice in the form of an Officers' Certificate
of any Event of Default under clause (6), (10), (11) or (12) and any event which
with the giving of notice or the lapse of time would become


<PAGE>

                                                                              47

an Event of Default under clause (4), (5) or (9), its status and what action the
Company is taking or proposes to take with respect thereto.

                  SECTION 6.02. ACCELERATION. If an Event of Default (other than
an Event of Default specified in Section 6.01(7) or (8) with respect to the
Company) occurs and is continuing, the Trustee by notice to the Company, or the
Holders of at least 25% in principal amount of the Securities then outstanding
by notice to the Company and the Trustee, may declare the principal of and
accrued but unpaid interest on all the Securities to be due and payable. Upon
such a declaration, such principal and interest shall be due and payable
immediately. If an Event of Default specified in Section 6.01(7) or (8) with
respect to the Company occurs, the principal of and interest on all the
Securities shall IPSO FACTO become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Securityholders.
The Holders of a majority in principal amount of the Securities by notice to the
Trustee may rescind an acceleration and its consequences if the rescission would
not conflict with any judgment or decree and if all existing Events of Default
have been cured or waived except nonpayment of principal or interest that has
become due solely because of acceleration. No such rescission shall affect any
subsequent Default or impair any right consequent thereto.

                  SECTION 6.03. OTHER REMEDIES. If an Event of Default occurs
and is continuing, the Trustee may pursue any available remedy to collect the
payment of principal of or interest on the Securities or to enforce the
performance of any provision of the Securities or this Indenture.

                  The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Securityholder 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 acquies cence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

                  SECTION 6.04. WAIVER OF PAST DEFAULTS. The Holders of a
majority in principal amount of the Securities by notice to the Trustee may
waive an existing Default and its consequences except (i) a Default in the
payment of the principal of or interest on a Security or (ii) a Default in
respect of a provision that under Section 9.02 cannot be amended without the
consent of each Securityholder affected.


<PAGE>

                                                                              48

When a Default is waived, it is deemed cured, but no such waiver shall extend to
any subsequent or other Default or impair any consequent right.

                  SECTION 6.05. CONTROL BY MAJORITY. The Holders of a majority
in principal amount of the Securities may direct the time, method and place of
conducting any proceed ing for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 7.01, that the Trustee determines is unduly prejudicial to
the rights of other Securityholders or would involve the Trustee in personal
liability; PROVIDED, HOWEVER, that the Trustee may take any other action deemed
proper by the Trustee that is not inconsistent with such direction. Prior to
taking any action hereunder, the Trustee shall be entitled to indemni fication
satisfactory to it in its sole discretion against all losses and expenses caused
by taking or not taking such action.

                  SECTION 6.06. LIMITATION ON SUITS. Except to enforce the right
to receive payment of principal, premium (if any) or interest when due, no
Securityholder may pursue any remedy with respect to this Indenture or the
Securities unless:

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

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

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

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

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

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

to receive payment of princi pal of and interest on the Securities held by such
Holder, on or after the respective due dates expressed in the Secu rities, 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(1) or (2) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust
against the Company for the whole amount then due and owing (together with
interest on any unpaid interest to the extent lawful) and the amounts provided
for in Section 7.07.

                  SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee
may file such proofs of claim and other papers or documents as may be necessary
or advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, its creditors or
its property and, unless prohibited by law or applicable regulations, may vote
on behalf of the Holders in any election of a trustee in bankruptcy or other
Person performing similar functions, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disburse ments and advances of the Trustee,
its agents and its counsel, and any other amounts due the Trustee under Section
7.07.

                  SECTION 6.10.  PRIORITIES.  If the Trustee col
lects any money or property pursuant to this Article 6, it
shall pay out the money or property in the following order:

                  FIRST:  to the Trustee for amounts due under
         Section 7.07;

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

                  THIRD:  to the Company.

                  The Trustee may fix a record date and payment date for any
payment to Securityholders pursuant to this Section. At least 15 days before
such record date, the Company shall mail to each Securityholder and the Trustee
a notice that states the record date, the payment date and amount to be paid.

                  SECTION 6.11. UNDERTAKING FOR COSTS. In any suit for the
enforcement of any right or remedy under this Inden ture or in any suit against
the Trustee for any action taken or omitted by it as Trustee, a court in its
discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including rea sonable attorneys' fees, against any
party litigant in the suit, having due regard to the merits and good faith of
the claims or defenses made by the party litigant. This Section does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit
by Holders of more than 10% in principal amount of the Securities.

                  SECTION 6.12. WAIVER OF STAY OR EXTENSION LAWS. The Company
(to the extent it may lawfully do so) shall not at any time insist upon, or
plead, or in any manner whatso ever claim or take the benefit or advantage of,
any stay or extension law wherever enacted, now or at any time hereafter in
force, which may affect the covenants or the performance of this Indenture; and
the Company (to the extent that it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law, and shall not hinder, delay or impede
the execution of any power herein granted to the Trustee, but shall suffer and
permit the execution of every such power as though no such law had been enacted.


                                    ARTICLE 7

                                     TRUSTEE

                  SECTION 7.01. DUTIES OF TRUSTEE. (a) If an Event of Default
has occurred and is continuing, the Trustee shall exercise the rights and powers

                                                                              51

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

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

                  (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the require ments
         of this Indenture and the Security Agreements. However, the Trustee
         shall examine the certificates and opinions to determine whether or not
         they conform to the requirements of this Indenture and the Security
         Agreements.

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

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

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

                  (3) the Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith in accordance with a direction
         received by it pursuant to Section 6.05.

                  (d) Every provision of this Indenture and the Security

                  (e) 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.

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

                                                                              52

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

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

                  SECTION 7.02.  RIGHTS OF TRUSTEE.  (a)  The
Trustee may rely on any document believed by it to be genu
ine and to have been signed or presented by the proper per
son.  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 Opin ion of Counsel or such other
information as it may reasonably request. The Trustee shall not be liable for
any action it takes or omits to take in good faith in reliance on the Officers'
Certificate or Opinion of Counsel.

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

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

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

                  SECTION 7.03.  INDIVIDUAL RIGHTS OF TRUSTEE.  The
Trustee in its individual or any other capacity may become
the owner or pledgee of Securities and may otherwise deal
with the Company or its Affiliates with the same rights it


<PAGE>

                                                                              53

would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or
co-paying agent may do the same with like rights. However, the Trustee must
comply with Sections 7.10 and 7.11.

                  SECTION 7.04. TRUSTEE'S DISCLAIMER. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture, the Security Agreements or the Securities, it shall not be
accountable for the Company's use of the proceeds from the Securities, and it
shall not be responsible for any statement of the Company in this Indenture, the
Security Agreements or in any document issued in connection with the sale of the
Securities or in the Securities other than the Trustee's certificate of
authentication.

                  SECTION 7.05. NOTICE OF DEFAULTS. If a Default occurs and is
continuing and if it is known to the Trustee, the Trustee shall mail to each
Securityholder notice of the Default within 90 days after it occurs. Except in
the case of a Default in payment of principal of or interest on any Security
(including payments pursuant to the redemption provisions of such Security, if
any), the Trustee may withhold the notice if and so long as a committee of its
Trust Officers in good faith determines that withholding the notice is in the
interests of Securityholders.

                  SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS. As promptly as
practicable after each May 15 beginning with the May 15 following the date of
this Indenture, and in any event prior to July 31 in each year, the Trustee
shall mail to each Securityholder a brief report dated as of May 15 that
complies with TIA ss. 313(a). The Trustee also shall comply with TIA ss. 313(b).

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

                  SECTION 7.07. COMPENSATION AND INDEMNITY. (a) The Company
shall pay to the Trustee from time to time reasonable compensation for its
services. The Trustee's compensation shall not be limited by any law on
compensation of fiduciaries or a trustee of an express trust. The Company shall
reimburse the Trustee upon request for all reasonable out-of-pocket expenses
incurred or made by it, including costs of collection, in addition to the


<PAGE>

                                                                              54

compensation for its services. Such expenses shall include the reasonable
compensation and expenses, disbursements and advances of the Trustee's agents,
counsel, accountants and experts.

                  (b) The Company shall indemnify the Trustee and hold it
harmless from and against any and all loss, liability or expense (including
attorneys' fees) incurred by it in connection with the administration of this
trust and the performance of its duties hereunder and under the Security
Agreements. 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 may have separate counsel and the Company shall pay the
fees and expenses of such counsel. The Company need not reimburse any expense or
indemnify against any loss, liability or expense incurred by the Trustee through
the Trustee's own wilful misconduct, negligence or bad faith.

                  (c) In addition to, but without duplication of, its
obligations under subsection (b) above, the Company shall indemnify and hold
harmless the Trustee and the Securityholders from and against any and all
losses, damages and expenses incurred by the Trustee and the Securityholders as
a result of any environmental damage resulting from the operation of any Vessel.

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

                  (e) The Company's payment obligations pursuant to this Section
shall survive the discharge of this Indenture. When the Trustee incurs expenses
after the occurrence of a Default specified in Section 6.01(7) or (8) with
respect to the Company, the expenses are intended to constitute expenses of
administration under the Bankruptcy Law.

                  SECTION 7.08. REPLACEMENT OF TRUSTEE. The Trustee may resign
at any time by so notifying the Company. The Holders of a majority in principal
amount of the Secur ities then outstanding may remove the Trustee by so
notifying the Trustee and may appoint a successor Trustee.
The Company shall remove the Trustee if:

Securityholder may petition any court of competent jurisdiction for the removal

consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking

                  In case at the time such successor or successors by merger,
conversion or consolidation to the Trustee shall succeed to the trusts created
by this Indenture any of the Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities either in the name of any predecessor hereunder or in the name of the

operation of TIAss. 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of
the Company are out standing if the requirements for such exclusion set forth in
TIAss. 310(b)(1) are met.

                  SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST
COMPANY. The Trustee shall comply with TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been
removed shalL be subject to TIA ss. 311(a) to the extent indicated.

                  SECTION 7.12. NOT ACTING IN INDIVIDUAL CAPACITY. Except as
otherwise provided in this Indenture, the Trustee acts hereunder solely as
trustee as herein provided and not in its individual capacity, and all persons,

                       DISCHARGE OF INDENTURE; DEFEASANCE

                  SECTION 8.01. DISCHARGE OF LIABILITY ON SECURI TIES;
DEFEASANCE. (a) When (i) the Company delivers to the Trustee all outstanding
Securities (other than Securities replaced pursuant to Section 2.06) for
cancelation or (ii) all outstanding Securities have become due and payable,
whether at maturity or as a result of the mailing of a notice of redemption
pursuant to Article 3 hereof and the Company irrevocably deposits with the
Trustee funds suffi cient to pay at maturity or upon redemption all outstanding
Securities, including interest thereon to maturity or such redemption date
(other than Securities replaced pursuant to Section 2.06), and if in either case
the Company pays all other sums payable hereunder by the Company, then this
Indenture and the Security Agreements shall, subject to Sections 8.01(c), cease
to be of further effect. The Trustee shall acknowledge satisfaction and
discharge of this Indenture and the Security Agreements on demand of the Company
accompanied by an Officers' Certificate and an Opinion of Counsel and at the

contained in Sections 5.01(a)(iv) and 5.01(b), each Guarantor's obligations

option"). The Company may exercise its legal defeasance option notwithstanding
its prior exercise of its covenant defeasance option.

                  If the Company exercises its legal defeasance option, payment
of the Securities may not be accelerated because of an Event of Default with
respect thereto. If the Company exercises its covenant defeasance option,
payment of the Securities may not be accelerated because of an Event of Default
specified in Sections 6.01(4), 6.01(6), 6.01(7), 6.01(8) 6.01(9), 6.01(10),

Security Agreements.

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

                  (c) Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.07 and 7.08 and in
this Article 8 shall survive until the Securities have been paid in full.
Thereafter, the Company's obligations in Sections 7.07, 8.04 and 8.05 shall
survive.

                  SECTION 8.02.  CONDITIONS TO DEFEASANCE.  The
Company may exercise its legal defeasance option or its
covenant defeasance option only if:

                  (1) the Company irrevocably deposits in trust with
          the Trustee money or U.S. Government Obligations for
         the payment of principal of and interest on the Secu

                  (2) the Company delivers to the Trustee a cer tificate from a
         nationally recognized firm of indepen dent accountants expressing their
         opinion that the pay ments of principal and interest when due and
         without reinvestment on the deposited U.S. Government Obliga tions plus
         any deposited money without investment will provide cash at such times
         and in such amounts as will be sufficient to pay principal and interest
         when due on all the Securities to maturity or redemption, as the case
         may be;

                  (3) 123 days pass after the deposit is made and during the
         123-day period no Default specified in Sections 6.01(7) or (8) with
         respect to the Company occurs which is continuing at the end of the
         period;

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

                  (5) the Company delivers to the Trustee an Opinion of Counsel

         regulated investment company under the Investment

         Internal Revenue Service a ruling, or (ii) since the date of this
         Indenture there has been a change in the applicable Federal income tax
         law, in either case to the effect that, and based thereon such Opinion
         of Counsel shall confirm that, the Securityholders will not recognize
         income, gain or loss for Federal income tax purposes as a result of
         such 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 defeasance had not occurred;

                  (7) in the case of the covenant defeasance option, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Security holders will not recognize income, gain or loss for
         Federal income tax purposes as a result of such cove nant defeasance

         same manner and at the same times as would have been the case if such
         covenant defeasance had not occurred;

                  (8) the Company delivers to the Trustee a letter from each of
         the Rating Agencies and which such Rating Agency confirms that the
         exercise of such legal defeasance option or covenant defeasance
         options, as the case may be, will not result in a downgrading of the
         rating issued by such Rating Agency then in effect with respect to the
         Securities; and

                  (9) the Company delivers to the Trustee an Offi cers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent to the defeasance and discharge of the Securities as
         contemplated by this Article 8 have been complied with.

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

                  SECTION 8.03. APPLICATION OF TRUST MONEY. The Trustee shall

them for the payment of principal or interest that remains unclaimed for two
years, and, thereafter, Securityholders entitled to the money must look to the
Company for payment as general creditors.

                  SECTION 8.05.  INDEMNITY FOR GOVERNMENT OBLIGA
TIONS.  The Company shall pay and shall indemnify the
Trustee against any tax, fee or other charge imposed on or
assessed against deposited U.S. Government Obligations or

unable to apply any money or U.S. Government Obligations in accordance with this
Article 8 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restrain ing or
otherwise prohibiting such application, the Company's and the Owners'
obligations under this Indenture, the Security Agreements and the Securities
shall be revived and reinstated as though no deposit had occurred pursuant to
this Article 8 until such time as the Trustee or Paying Agent is permitted to
apply all such money or U.S. Government Obligations in accordance with this
Article 8; PROVIDED, HOWEVER, that, if the Company has made any payment of
interest on or principal of any Securities because of the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money or U.S. Government
Obligations held by the Trustee or Paying Agent.

                  (2) to comply with Article 5;

                  (3) to provide for uncertificated Securities in addition to or

                  SECTION 9.02.  WITH CONSENT OF HOLDERS.  The

<PAGE>

                                                                              62

                  (6) make any changes in the Security Agreements or in Articles
         10 or 11 that adversely affect the Holders or would terminate the Lien

         thereto or deprive the Holder of the security afforded by the Lien of
         this Indenture or the Security Agreements;

                  (7) make any change in Section 6.04 or 6.07 or the

                  It shall not be necessary for the consent of the Holders under

shall be sufficient if such consent approves the substance thereof.

amendment to this Indenture, the Security Agreements or the Securities shall
comply with the TIA as then in effect.

                  SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS AND WAIVERS. A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subse quent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subse quent Holder may revoke the consent or waiver as to such
Holder's Security or portion of the Security if the Trustee receives the notice
of revocation before the date the amendment or waiver becomes effective. After
an amendment or waiver becomes effective, it shall bind every Security holder.
An amendment or waiver becomes effective upon the execution of such amendment or
waiver by the Trustee.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Securityholders entitled to give their
consent or take any other action described above or required or permitted to be
taken pursuant to this Indenture. If a record date is fixed, then

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

                  SECTION 9.06. TRUSTEE TO SIGN AMENDMENTS. The Trustee shall
sign any amendment authorized pursuant to this Article 9 if the amendment does
not adversely affect the rights, duties, liabilities or immunities of the
Trustee.

                                                                              64

If it does, the Trustee may but need not sign it. In sign ing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Section 7.01) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that such
amendment is authorized or permit ted by this Indenture.

                  SECTION 9.07. PAYMENT FOR CONSENT. Neither the Company nor any
Affiliate of the Company shall, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
for or as an inducement to any consent, waiver or amendment of any of the terms
or provisions of this Indenture or the Securities unless such consideration is
offered to be paid to all Holders that so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.

Holder and to the Trustee and its successors and assigns (a) the full and
punctual payment of principal of and interest on the Securities when due,

Guarantors under this Indenture and the Securities and of the Owners under the
Security Agreements and (b) the full and punctual performance within applicable
grace periods of all other obligations of the Company and the other Guarantors

Guarantor further agrees that the Obligations may be extended or renewed, in
whole or in part, without notice or further assent from such Guarantor and that
such Guarantor will remain bound under this Article 10 notwithstanding any
extension or renewal of any Obligation.

                  Each Guarantor waives presentation to, demand of, payment from
and protest to the Company of any of the Obligations and also waives notice of
protest for nonpayment. Each Guarantor waives notice of any default under the
Securities or the Obligations. The obligations of each Guarantor hereunder shall
not be affected by (a) the

failure of any Holder or the Trustee to assert any claim or demand or to enforce
any right or remedy against the Company or any other Person under this
Indenture, the Security Agreements, the Securities or any other agreement or
otherwise; (b) any extension or renewal of any thereof; (c) any rescission,
waiver, amendment or modification of any of the terms or provisions of this
Indenture, the Security Agreements, the Securities or any other agreement; (d)
the release of any security held by any Holder or the Trustee for the
Obligations or any of them; (e) the failure of any Holder or the Trustee to
exercise any right or remedy against any other guarantor of the Obligations; or
(f) subject to Section 10.06, any change in the ownership of such Guarantor.

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

                  Except as expressly set forth in Sections 8.01(b), 10.02 and
10.06, the obligations of each Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including any
claim of waiver, release, surrender, alteration or compromise, and shall not be
subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
Obligations or otherwise. Without limiting the generality of the foregoing, the
obligations of each Guarantor herein shall not be discharged or impaired or
otherwise affected by the failure of any Holder or the Trustee to assert any
claim or demand or to enforce any remedy under this Indenture, the Security
Agreements, the Securities or any other agreement, by any waiver or modification
of any thereof, by any default, failure or delay, willful or otherwise, in the
performance of the obligations, or by any other act or thing or omission or
delay to do any other act or thing which may or might in any manner or to any
extent vary the risk of such Guarantor or would otherwise operate as a discharge
of such Guarantor as a matter of law or equity.

                  Each Guarantor further agrees that its Guarantee herein shall
continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of principal of or interest on any Obligation is
rescinded or must otherwise be restored by any Holder or the


<PAGE>

                                                                              66

Trustee upon the bankruptcy or reorganization of the Company or otherwise.

                  In furtherance of the foregoing and not in limitation of any
other right which any Holder or the Trustee has at law or in equity against any
Guarantor by virtue hereof, upon the failure of the Company to pay the principal
of or interest on any Obligation when and as the same shall become due, whether
at maturity, by acceleration, by redemption or otherwise, or to perform or
comply with any other Obligation, each Guarantor hereby promises to and will,
upon receipt of written demand by the Trustee, forthwith pay, or cause to be
paid, in cash, to the Holders or the Trustee an amount equal to the sum of (i)
the unpaid amount of such Obligations, (ii) accrued and unpaid interest on such
Obligations (but only to the extent not prohibited by law) and (iii) all other
monetary Obligations of the Company or the Guarantors to the Holders and the
Trustee.

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

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

                  SECTION 10.02. LIMITATION ON LIABILITY. Any term or provision
of this Indenture to the contrary notwith standing, the maximum aggregate amount
of the Obligations guaranteed hereunder by any Owner shall not exceed the
maximum amount that can be hereby guaranteed without rendering this Indenture,
as it relates to such Owner, voidable under applicable law relating to
fraudulent conveyance or fraudulent transfer or similar laws affecting the
rights of creditors generally.

                  SECTION 10.03. SUCCESSORS AND ASSIGNS. This Article 10 shall
be binding upon each Guarantor and its successors and assigns and shall enure to
the benefit of the

                                                                              67

successors and assigns of the Trustee and the Holders and, in the event of any
transfer or assignment of rights by any Holder or the Trustee, the rights and
privileges conferred upon that party in this Indenture, in the Security
Agreements and in the Securities shall automatically extend to and be vested in
such transferee or assignee, all subject to the terms and conditions of this
Indenture.

                  SECTION 10.04. NO WAIVER. Neither a failure nor a delay on the
part of either the Trustee or the Holders in exercising any right, power or
privilege under this Article 10 shall operate as a waiver thereof, nor shall a
single or partial exercise thereof preclude any other or further exercise of any
right, power or privilege. The rights, remedies and benefits of the Trustee and
the Holders herein expressly specified are cumulative and not exclusive of any
other rights, remedies or benefits which either may have under this Article 10
at law, in equity, by statute or otherwise.

                  SECTION 10.05. MODIFICATION. No modification, amendment or
waiver of any provision of this Article 10, nor the consent to any departure by
any Guarantor therefrom, shall in any event be effective unless the same shall
be in writing and signed by the Trustee, and then such waiver or consent shall
be effective only in the specific instance and for the purpose for which given.
No notice to or demand on any Guarantor in any case shall entitle such Guarantor
to any other or further notice or demand in the same, similar or other
circumstances.

                  SECTION 10.06. RELEASE OF GUARANTOR. Upon the sale or other
disposition (including by way of consolidation or merger) of an Owner or the
sale or disposition of all or substantially all the assets of such Owner (in
each case other than to the Company or an Affiliate of the Company), such Owner
shall be deemed released from all obligations under this Article 10 without any
further action required on the part of the Trustee or any Holder. At the request
of the Company and upon receipt of an Officers' Certificate, the Trustee shall
execute and deliver an appropriate instrument evidencing such release.

acknowledge and agree that the Collateral Agent holds the Collateral in trust

deemed to have agreed to all the terms and provisions of the Security
Agreements.

                  (b) As among the Holders, the Collateral shall be held for the
equal and ratable benefit of such holders without preference, priority or

amendments thereto and any other instruments of further assurance.

                  (b)  The Company and the Owners shall furnish to

         filing) to the extent necessary to make effective the Lien created by
         such Security Agreements and reciting the details of such action, and

         proper provision has been made for such filing) that are necessary
         fully to preserve and protect the rights of the Holders and the Trustee

                  SECTION 11.03. DISPOSITION OF COLLATERAL WITHOUT RELEASE. (a)
Notwithstanding the provisions of Section 11.04, so long as no Event of Default
shall have occurred

and be continuing, the Company and any Owner, as appropriate, may, without any
release or consent by the Trustee:

                  (i) sell or otherwise dispose of any machinery, equipment,
         furniture, apparatus, tools or implements, materials or supplies or
         other similar property subject to the Lien of this Indenture and the
         Security Agreements, which may have become worn out or obsolete, not
         exceeding in aggregate value in any one calendar year $1,000,000, or
         which may constitute an Incidental Asset, upon substituting for the
         same other machinery, equipment, furniture, apparatus, tools or
         implements, materials or supplies or other similar property not
         necessarily of the same character but of at least equal value to the
         Company as, and costing not less than the amount realized from, the
         Collateral disposed of, which shall forthwith become, without further
         action, subject to the Lien of this Indenture and the Security
         Agreements;

                  (ii) abandon, terminate, cancel, release or make alterations
         in or substitutions of any contracts subject to the Lien of this
         Indenture and any of the Security Agreements; PROVIDED, HOWEVER, that
         any altered or substituted contracts shall forthwith, without further
         action, be subject to the Lien of this Indenture and the Security
         Agreements to the same extent as those previously existing;

                  (iii) surrender or modify any franchise, license or permit
         subject to the Lien of this Indenture and any of the Security
         Agreements which it may own or under which it may be operating;
         PROVIDED, HOWEVER, that, after the surrender or modification of any
         such franchise, license or permit, the Company or the applicable Owner
         shall still, in the reasonable opinion of the Board of Directors of the
         Company, be entitled, under some other or without any franchise,
         license or permit, to conduct its business as it was operating
         immediately prior to such surrender or modification;

                  (iv) alter, repair, replace and add to its plants, structures,

         HOWEVER, that such alteration, repair or replacement shall comply with

         opinion of the Board of Directors, be prejudicial to the interests of
         the Holders; or


<PAGE>

                                                                              71

                  (v) demolish, dismantle, tear down or scrap any portion of the
         Collateral (other than a Vessel), if in the good faith opinion of the
         Board of Directors, as evidenced by a Board Resolution, such
         demolition, dis mantling, tearing down or scrapping is in the best
         interests of the Company and the fair market value and utility of the
         Collateral as an entirety, and the security for the Securities, will
         not thereby be impaired.

                  (b) In the event that the Company or an Owner has sold,
exchanged or otherwise disposed of or proposes to sell, exchange or otherwise
dispose of any portion of the Collateral which under the provisions of this
Section 11.03 may be sold, exchanged or otherwise disposed of by the Company
without any release or consent of the Trustee or the Collateral Agent, and the
Company requests the Trustee to furnish a written disclaimer, release or
quitclaim of any interest in such property under this Indenture and the Security
Agreements, the Trustee shall execute such an instrument upon delivery to the
Trustee of (i) an Officers' Certificate by the Company reciting the sale,
exchange or other disposition made or proposed to be made and describing in
reasonable detail the property affected thereby, and stating that such property
is property which by the provisions of this Section 11.03 may be sold, exchanged
or otherwise disposed of or dealt with by the Company without any release or
consent of the Trustee and (ii) an Opinion of Counsel stating that the sale,
exchange or other disposition made or proposed to be made was duly taken by the
Company or the Owner in conformity with a designated subsection of Section
11.03(a) and that the execution of such written disclaimer, release or quitclaim
is appropriate to confirm the propriety of such sale, disposition or other
disposition under this Section 11.03.

                  SECTION 11.04. RELEASE OF COLLATERAL. Collateral may be
released from the security interest created by the Security Agreements at any
time or from time to time in accordance with the provisions of the Security
Agreements. The release of any Collateral from the terms hereof and of the
Security Agreements or the release of, in whole or in part, the Liens created by
the Security Agreements, will not be deemed to impair the Lien on the Collateral
in contravention of the provisions hereof if and to the extent the Collateral or
Liens are released pursuant to the applicable Security Agreements and pursuant
to the terms of this Article 11. The Trustee and each of the Holders acknowledge
that a release of Collateral or a Lien strictly in accordance with the terms of
the Security Agreements and


<PAGE>

                                                                              72

of this Article 11 will not be deemed for any purpose to be an impairment of the
Lien on the Collateral in contravention of the terms of this Indenture. To the
extent applicable, the Company and each obligor on the Securities shall cause
ss. 314(d) of the TIA relating to the release of property or securities from the
Lien hereof and of the Security Agreements to be complied with. Any certificate
or opinion required by ss. 314(d) of the TIA may be made by an officer of the
Company, except in cases which ss. 314(d) of the TIA requires that such
certificate or opinion be made by an independent person.

                  SECTION 11.05. PERMITTED RELEASES NOT TO IMPAIR LIEN; TRUST
INDENTURE ACT REQUIREMENTS. The release of any Collateral from the terms hereof
and of the Security Agreements or the release of, in whole or in part, the Liens
created by the Security Agreements, will not be deemed to impair the Lien on the
Collateral in contravention of the provisions hereof if and to the extent the
Collateral or Liens are released pursuant to the applicable Security Agreements
and pursuant to the terms of this Article 11. The Trustee and each of the
Holders acknowledge that a release of Collateral or a Lien strictly in
accordance with the terms of the Security Agreements and of this Article 11 will
not be deemed for any purpose to be an impairment of the Lien on the Collateral
in contravention of the terms of this Indenture. To the extent applicable, the
Company and each obligor on the Securities shall cause ss. 314(d) of the TIA
relating to the release of property or securities from the Lien hereof and of
the Security Agreements to be complied with. Any certificate or opinion required
by ss. 314(d) of the TIA may be made by an officer of the Company, except in
cases which ss. 314(d) of the TIA requires that such certificate or opinion be
made by an independent person.

                  SECTION 11.06. SUITS TO PROTECT THE COLLATERAL. Subject to the
provisions of the Security Agreements, the Trustee shall have power to institute
and to maintain such suits and proceedings as it may deem expedient to prevent
any impairment of the Collateral by any acts which may be unlawful or in
violation of any of the Security Agreements or this Indenture, and such suits
and proceedings as the Trustee, in its sole discretion, may deem expedient to
preserve or protect its interests and the interests of the Holders in the
Collateral (including power to institute and maintain suits or proceedings to
restrain the enforcement of or compliance with any legislative or other
governmental enactment, rule or order that may be unconstitutional or otherwise
invalid if the enforcement of, or compliance with,


<PAGE>

                                                                              73

such enactment, rule or order would impair the Lien on the Collateral or be
prejudicial to the interests of the Holders or the Trustee).

                  SECTION 11.07. PURCHASER PROTECTED. In no event shall any
purchaser in good faith of any property purported to be released hereunder be
bound to ascertain the authority of the Trustee or the Collateral Agent to
execute the release or to inquire as to the satisfaction of any conditions
required by the provisions hereof or of the Security Agreements for the exercise
of such authority or to see to the application of any consideration given by
such purchaser or other transferee; nor shall any purchaser or other transferee
of any property or rights permitted by this Article 11 to be sold be under
obligation to ascertain or inquire into the authority of the Company or the
applicable Owner to make any such sale or other transfer.

                  SECTION 11.08. POWERS EXERCISABLE BY RECEIVER OR TRUSTEE. In
case the Collateral shall be in the possession of a receiver or trustee,
lawfully appointed, the powers conferred in this Article 11 upon the Company or
an Owner with respect to the release, sale or other disposition of such property
may be exercised by such receiver or trustee, and an instrument signed by such
receiver or trustee shall be deemed the equivalent of any similar instrument of
the Company or an Owner or of any officer or officers thereof required by the
provisions of this Article 11; and if the Trustee or the Collateral Agent shall
be in the possession of the Collateral under any provision of this Indenture,
then such powers may be exercised by the Trustee or the Collateral Agent.

                  SECTION 11.09. DISPOSITION OF OBLIGATIONS RECEIVED. All
purchase money and other obligations received by the Collateral Agent under this
Article 11 shall be held by the Trustee as a part of the Collateral. Upon
payment in cash or cash equivalents by or on behalf of the Company to the
Collateral Agent of the entire unpaid principal amount of any such obligation,
the Trustee shall or the Collateral Agent release and transfer such obligation
and any mortgage securing the same upon receipt of any documentation that the
Trustee may reasonably require. Any cash or cash equivalents received by the
Collateral Agent in respect of the principal of any such obligations shall be
held by the Collateral Agent as Trust Moneys under the Intercreditor Agreement
subject to application as therein provided and as provided in the Security
Agreements. All interest and other income on any such obligations, when received
by the

                                                                              74

Collateral Agent shall be held and applied in accordance with the Intercreditor
Agreement.

                  SECTION 11.10. DETERMINATIONS RELATING TO COLLATERAL. In the
event (i) the Trustee shall receive any written request from the Company or an
Owner under any Security Agreement for consent or approval with respect to any
matter or thing relating to any Collateral or the Company's or an Owner's
obligations with respect thereto or (ii) there shall be due to or from the
Trustee under the provisions of any Security Agreement any material performance
or the delivery of any material instrument or (iii) the Trustee shall become
aware of any material nonperformance by the Company or an Owner of any covenant
or any material breach of any representation or warranty of the Company or an
Owner set forth in any Security Agreement, then, in each such event, the Trustee
shall be entitled to hire, at the sole reasonable cost and expense of the
Company, experts, consultants, agents and attorneys to advise the Trustee on the
manner in which the Trustee should respond, to such request or render any
requested performance or response to such nonperformance or breach. The Trustee
shall be fully protected in accordance with Article 7 hereof in the taking of
any action recommended or approved by any such expert, consultant, agent or
attorney and by indemnification provided in accordance with Section 6.05 and
other sections of this Indenture if such action is agreed to by Holders of a
majority in principal amount of the Securities pursuant to Section 6.05 and, the
Trustee may, in its sole discretion, prior to taking such action if such action
could subject it to environmental liabilities or taxation, require (i) direction
from the Holders of a majority in principal amount of the Securities in
accordance with Section 6.05 hereof and (ii) indemnification in accordance with
Section 6.05.

                  SECTION 11.11. RELEASE UPON TERMINATION OF THE COMPANY'S
OBLIGATIONS. In the event that the Company delivers an Officers' Certificate
certifying that all the obligations under this Indenture, the Securities and the
Security Agreements have been satisfied and discharged by complying with the
provisions of Article 8 or by the payment in full of the Company's obligations
under the Securities, this Indenture and the Security Agreements, the Trustee
shall deliver to the Company a notice stating that the Trustee, on behalf of the
Holders, disclaims and gives up any and all rights it has in or to the
Collateral, and any rights it has under the Security Agreements.

         Section 2.08 of the Indenture, prior to the consummation of a
         Registered Exchange Offer or the effectiveness of a Shelf Registration
         Statement with respect to such Securities, such Securities may be
         exchanged only in accordance with such procedures as are substantially
         consistent with the provisions of this Section 2.3 (including the
         certification requirements set forth on the reverse of the Initial
         Securities intended to ensure that such transfers comply with Rule 144A
         or Regulation S, as the case may be) and such other procedures as may

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

                  (iii) After a transfer of any Initial Securities or Private
         Exchange Securities during the period of the effectiveness of a Shelf
         Registration Statement with respect to such Initial Securities or
         Private Exchange Securities, as the case may be, all requirements
         pertaining to legends on such Initial Security or such Private Exchange
         Security will cease to apply, the requirements that any such Initial
         Security or such Private Exchange Security issued to certain Holders be
         issued in global form will cease to apply, and a certificated Initial
         Security or Private Exchange Security without legends will be available
         to the transferee of the Holder of such Initial Securities or Private
         Exchange Securities upon exchange of such transferring Holder's

         their Initial Securities, all requirements pertaining to such Initial
         Securities that Initial Securities issued to certain Holders be issued
         in global form will cease to apply and certificated Initial Securities

         to the Initial Securities pursuant to which Holders of such Initial
         Securities are offered Private Exchange Securities in exchange for
         their Initial Securities, all requirements pertaining to such Initial
         Securities that Initial Securities issued to certain Holders be issued
         in global form will still apply, and Private Exchange Securities in
         global form with the Restricted Securities Legend set forth in Exhibit

                  (c) CANCELATION OR ADJUSTMENT OF GLOBAL SECURITY. At such time
as all beneficial interests in a Global Security have either been exchanged for
certificated Securities, redeemed, repurchased or canceled, such Global Security
shall be returned to the Depositary for cancelation or retained and canceled by
the Trustee. At any time prior to such cancelation, if any beneficial interest
in a Global Security is exchanged for certificated Securities, redeemed,
repurchased or canceled, the principal amount of Securities represented by such
Global Security shall be reduced and an adjustment shall be made on the books
and records of the Trustee (if it is then the Securities Custodian for such
Global Security) with respect to such Global Security, by the Trustee or the
Securities Custodian, to reflect such reduction.

co-registrar's request.

         transfer or exchange, but the Company may require payment of a sum
         sufficient to cover any transfer tax, assessments, or similar
         governmental charge payable in connection therewith (other than any
         such transfer taxes, assessments or similar governmental charge payable
         upon exchange or transfer pursuant to Sections 3.06, 4.12 and 9.05).

                  (iii) The Registrar or co-registrar shall not be

         co-registrar shall be affected by notice to the contrary.

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

                  (e) NO OBLIGATION OF THE TRUSTEE. (i) The Trustee shall have
no responsibility or obligation to any beneficial owner of a Global Security, a
member of, or a participant in the Depositary or other Person with respect to
the accuracy of the records of the Depositary or its nominee or of any
participant or member thereof, with respect to any ownership interest in the
Securities or with respect to the delivery to any participant, member,

installments of interest at the same rate to the extent lawful.

represented by a Global Security (including principal, premium and interest)
will be made by wire transfer of immediately available funds to the accounts

respect of a certificated Security (including principal, premium and interest)
by mailing a check to the registered address of each Holder thereof; PROVIDED,
HOWEVER,

dollar account maintained by the payee with a bank in the United States if such
Holder elects payment by wire transfer by giving written notice to the Trustee
or the Paying Agent to such effect designating such account no later than 30
days immediately preceding the relevant due date for payment (or such other date
as the Trustee may accept in its discretion).


                  3.  PAYING AGENT AND REGISTRAR

                  Initially, United States Trust Company of New York, a bank and
trust company organized under the New York Banking Law ("Trustee"), will act as
Paying Agent and Registrar. The Company may appoint and change any Paying Agent,
Registrar or co-registrar without notice. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or
co-registrar.

the Trustee. The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of

(the "Act"). Terms defined in the Indenture and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
such terms, and Securityholders are referred to the Indenture and the Act for a
statement of those terms.

                  The Securities are general secured obligations of the Company
limited to $217,000,000 aggregate principal amount (subject to Section 2.06 of
the Indenture). The Indenture limits (i) the incurrence of additional debt by
the Company and the Owner, (ii) the payment of dividends on capital stock of the
Company and the purchase, redemption or retirement of capital stock or
subordinated indebtedness, (iii) investments, (iv) certain liens and
sale/leaseback transactions, (v) certain transactions with affiliates, (vi)

Jurisdiction, or of any political subdivision or taxing authority thereof or
therein, or any change in the official administration, application or
interpretation of such laws, regulations or published tax rulings either
generally or in relation to any particular Securities, which change in official
administration, application or interpretation shall not have been available to
the public prior to such issue date and is notified to the Company or the
relevant Owners, as the case may be, on or after such issue date, it is
determined by the Company or the relevant Owners, as the case may be, that the
Company or the relevant Owners, as the case may be, would be required to pay,
any Additional Amounts pursuant to the Indenture or the terms of any Security in
respect of interest on the next succeeding Interest Payment Date (assuming, in
the case of the Owners, that a payment in respect of such interest were required
to be made by the relevant Owners under the Guarantees on such Interest Payment
Date), and that such obligation cannot be avoided by the Company or the relevant
Owners taking reasonable measures available to it, the Company or the relevant
Owners, as the case may be, may, at its option, redeem all (but not less than
all) the Securities in respect of which such Additional Amounts would be so
payable at any time, at a redemption price equal to 100% of the principal amount
thereof plus accrued interest to the date fixed for redemption; PROVIDED,
HOWEVER, that (a) no such notice of

                                                                               7

redemption may be given earlier than 60 days prior to the earliest date on which
the Company or the relevant Owners, as the case may be, would be obligated, or
is substantially likely to be obligated, to pay such Additional Amounts were a
payment in respect of the Securities or the Guarantees, as the case may be, then
due, and (b) at the time any such redemption notice is given, such obligation,
or substantial likelihood, to pay such Additional Amounts must remain in effect.

                  In addition, at any time and from time to time prior to June
30, 2000, the Company may redeem up to 35% of the aggregate principal amount of
Securities with the proceeds of one or more Public Equity Offerings (with the
cash proceeds thereof to the extent actually contributed to the Company)
following which there is a Public Market, at a redemption price (expressed as a
percentage of principal amount) of 110.5% plus accrued interest to the
redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the related interest payment date);
PROVIDED, HOWEVER, that at least $100 million aggregate principal amount of the
Securities and $45 million aggregate principal amount of the Second Priority
Notes must remain outstanding after each such redemption.


                  6.  MANDATORY REDEMPTION

                  In the event an Owner elects to terminate its Building
Contract because of a material breach thereof by the Builders (including a
failure to pay liquidated damages for any delay in the delivery of the related
Vessel), the Securities will be subject to mandatory redemption in part, on a
pro rata basis, in an aggregate principal amount equal to the Allocated
Principal Amount of the Securities for such Vessel and for each other Vessel
that has not been accepted by its related Owner as of the date of such
termination, at a redemption price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest to and including the date of

                  10.  SECURITY

                  The Securities will initially be secured by the Collateral
delivered on the Issue Date. Upon the occurrence of a Delivery Date with respect
to a Vessel the Securities will thereafter be secured by a first priority ship

Credit.


                  11.  DENOMINATIONS; TRANSFER; EXCHANGE

                  The Securities are in registered form without coupons in
denominations of $1,000 and whole multiples of $1,000. A Holder may transfer or

a Holder, among other things, to furnish appropriate endorse ments or transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture. The Registrar need not register the transfer of or exchange any
Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) or any

redeemed or 15 days before an interest payment date.

                  If money for the payment of principal or interest
remains unclaimed for two years, the Trustee or Paying Agent

any such payment, Holders entitled to the money must look only to the Company
and not to the Trustee for payment.


                  14.  DISCHARGE AND DEFEASANCE

                  Subject to certain conditions, the Company at any time may

principal and interest on the Securities to redemption or maturity, as the case
may be.


                  15.  AMENDMENT, WAIVER

                  Subject to certain exceptions set forth in the Indenture, (i)

any default or noncompliance with any provision may be waived with the written
consent of the Holders of a majority in principal amount of the Securities.
Subject to certain exceptions set forth in the Indenture, without the consent of
any Securityholder, the Company, the Guarantors and the Trustee may amend the
Indenture, the Security Agreements or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 5 of the Indenture,
or to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add additional guarantees with respect to the
Securities or to provide additional security for the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company or
the Guarantors, or to comply with any request of the SEC in connection with
qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Securityholder.


                  16.  DEFAULTS AND REMEDIES

                  Under the Indenture, Events of Default include (i) default for
30 days in payment of interest on the Securities; (ii) default in payment of

<PAGE>

                                                                              11

in the Indenture or the Securities, in certain cases subject to notice and lapse

the Owners if the amount accelerated (or so unpaid) exceeds $5.0 million; (v)
certain events of bankruptcy or insolvency with respect to Holdings, the Company
or the Owners; (vi) certain judgments or decrees for the payment of money in
excess of $5.0 million, (vii) certain events or defaults with respect to the

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

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


                  17.  TRUSTEE DEALINGS WITH THE COMPANY

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


                  18.  NO RECOURSE AGAINST OTHERS

                  A director, officer, employee or stockholder, as such, of the
Company, Holdings, the Owners or the Trustee shall not have any liability for
any obligations of the Company, Holdings or the Owners under the Securities or
the Indenture or for any claim based on, in respect of or by


<PAGE>

                                                                              12

reason of such obligations or their creation. By accepting a Security, each
Securityholder waives and releases all such liability. The waiver and release
are part of the considera tion for the issue of the Securities.


                  19.  AUTHENTICATION

1.  INTEREST

                  Navigator Gas Transport PLC, an Isle of Man public limited
company (such company, and its successors and assigns under the Indenture
hereinafter referred to, being herein called the "Company"), promises to pay
interest in cash on the principal amount of this Security at the rate per annum
shown above [; PROVIDED, HOWEVER, that if a Registration Default (as defined in
the Registration Rights Agreement) occurs, additional interest will accrue on
this Security at a rate of 0.50% per annum from and including the date on which
any such Registration Default shall occur to but excluding the date on which all
Registration Defaults have been cured] ***/. The Company will pay interest
semiannually on June 30 and December 31 of each year, commencing December 31,
1997. Interest on the Securities will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from August 7, 1997.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

in accordance with the Registration Rights Agreement.

defaulted interest) to the Persons who are registered holders of Securities at
the close of business on the June 15 or December 15 next preceding the interest
payment date even if Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying
Agent to collect principal payments. The Company will pay principal and interest
in money of the United States that at the time of payment is legal tender for
payment of public and private debts. Payments in respect of Securities
(including principal, premium and interest) will be made by wire transfer of
immediately available funds to the accounts specified by the holders thereof or,
if no U.S. dollar account maintained by the payee with a bank in the United
States is designated by any holder to the Trustee or the Paying Agent at least
30 days prior to the relevant due date for payment (or such other date as the
Trustee may accept in its discretion), by mailing a check to the registered
address of such holder.


3.  PAYING AGENT AND REGISTRAR

                  Initially, United States Trust Company of New York, a bank and
trust company organized under the New York Banking Law ("Trustee"), will act as
Paying Agent and Registrar. The Company may appoint and change any Paying Agent,
Registrar or co-registrar without notice. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or
co-registrar.


4.  INDENTURE

of August 1, 1997 ("Indenture"), among the Company, Holdings, the Guarantors and
the Trustee. The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of

statement of those terms.

respect of interest on the next succeeding Interest Payment Date (assuming, in
the case of the Owners, that a payment in respect of such interest were required
to be made by the relevant Owners under the Guarantees on such Interest Payment
Date), and that such obligation cannot be avoided by the Company or the relevant
Owners taking reasonable measures available to it, the Company or the relevant
Owners, as the case may be, may, at its option, redeem all (but not less than
all) the Securities in respect of which such Additional Amounts would be so

thereof plus accrued interest to the date fixed for redemption; PROVIDED,

redemption notice is given, such obligation, or substantial likelihood, to pay
such Additional Amounts must remain in effect.

the Company may redeem up to 35% of the aggregate principal amount of Securities
with the proceeds of one or more Public Equity Offerings (with the cash proceeds
thereof to the extent actually contributed to the Company) following which there
is a Public Market, at a redemption price (expressed as a percentage of
principal amount) of 110.5% plus accrued interest to the redemption date
(subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date); PROVIDED, HOWEVER,
that at least $100 million aggregate principal amount of the Securities and $45
million aggregate principal amount of the Second Priority Notes must remain
outstanding after each such redemption.


6.  MANDATORY REDEMPTION

failure to pay liquidated damages for any delay in the delivery of the related
Vessel), the Securities will be subject to mandatory redemption in part, on a
pro rata basis, in an aggregate principal amount equal to the Allocated
Principal Amount of the Securities for such Vessel and for each other Vessel

thereof, plus accrued and unpaid interest to the date of redemption (subject to
the right of a Holder of record on the relevant record date to receive interest

9.  GUARANTEE

and interest on, the Securities is fully and unconditionally guaranteed on a
joint and several senior basis by the Owners.


10.  SECURITY

                  The Securities will initially be secured by the Collateral
delivered at the Issue Date (as defined in the Intercreditor Agreement). Upon

                  The Securities are in registered form without coupons in
denominations of $1,000 and whole multiples of $1,000. A Holder may transfer or
exchange Securities in accordance with the Indenture. The Registrar may require
a Holder, among other things, to furnish appropriate endorse ments or transfer
documents and to pay any taxes and fees


<PAGE>

                                                                               9

required by law or permitted by the Indenture. The Registrar need not register
the transfer of or exchange any Securities selected for redemption (except, in
the case of a Security to be redeemed in part, the portion of the Security not
to be redeemed) or any Securities for a period of 15 days before a selection of
Securities to be redeemed or 15 days before an interest payment date.


12.  PERSONS DEEMED OWNERS

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


13.  UNCLAIMED MONEY

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


14.  DISCHARGE AND DEFEASANCE

                  Subject to certain conditions, the Company at any time may
terminate some or all of its and the Guarantors' obligations under the
Securities, the Security Agreements and the Indenture if the Company deposits
with the Trustee money or U.S. Government Obligations for the payment of
principal and interest on the Securities to redemption or maturity, as the case
may be.


15.  AMENDMENT, WAIVER

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount of the Securities and (ii)
any default or noncompliance with any provision may be waived with the written
consent of the Holders of a majority in principal amount of the Securities.
Subject to certain exceptions set forth in the Indenture, without the consent of
any Securityholder, the Company, the Guarantors and the Trustee may amend the
Indenture, the Security Agreements or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 5 of the Indenture,


<PAGE>

                                                                              10

or to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add additional guarantees with respect to the
Securities or to provide additional security for the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company or
the Guarantors, or to comply with any request of the SEC in connection with
qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Securityholder.


16.  DEFAULTS AND REMEDIES

                  Under the Indenture, Events of Default include (i) default for
30 days in payment of interest on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon redemption pursuant to para graph
5 or 6 of the Securities, upon required purchase, upon acceleration or
otherwise, or failure by the Company or the Guarantors to redeem or purchase
Securities when required; (iii) failure by the Company to comply with other
agreements in the Indenture or the Securities, in certain cases subject to
notice and lapse of time; (iv) certain accelerations (including failure to pay
within any grace period after final maturity) of other Indebtedness of Holdings,
the Company or the Owners if the amount accelerated (or so unpaid) exceeds $5.0
million; (v) certain events of bankruptcy or insolvency with respect to Holdings
and the Company or the Owners; (vi) certain judgments or decrees for the payment
of money in excess of $5.0 million, (vii) certain events or defaults with
respect to the Guarantees or the Security Agreements and (ix) the failure by the
Designated Owners to hold certain prescribed percentages of Voting Stock and
Capital Stock of Holdings. If an Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the Securities may
declare all the Securities to be due and payable immediately. Certain events of
bankruptcy or insolvency are Events of Default which will result in the
Securities being due and payable immediately upon the occurrence of such Events
of Default.

                  Securityholders may not enforce the Indenture or the
Securities except as provided in the Indenture. The Trustee may refuse to
enforce the Indenture or the Securities unless it receives reasonable indemnity
or security. Subject to certain limitations, Holders of a majority in principal
amount of the Securities may direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Securityholders notice of any continuing
Default (except a


<PAGE>

                                                                              11

Default in payment of principal or interest) if it determines that withholding
notice is in the interest of the Holders.


17.  TRUSTEE DEALINGS WITH THE COMPANY

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


18.  NO RECOURSE AGAINST OTHERS

                  A director, officer, employee or stockholder, as such, of the
Company, the Owners or the Trustee shall not have any liability for any
obligations of the Company or the Owners under the Securities or the Indenture
or for any claim based on, in respect of or by reason of such obligations or
their creation. By accepting a Security, each Securityholder waives and releases
all such liability. The waiver and release are part of the consideration for the

                                    ARTICLE 2

                                 THE SECURITIES

                  SECTION 2.01. FORM AND DATING. Provisions relating to the
Initial Securities, the Private Exchange Securities and the Exchange Securities
are set forth in the Rule 144A/Regulation S Appendix attached hereto (the
"Appendix") which is hereby incorporated in and expressly made part of this
Indenture. The Initial Securities and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit 1 to the Appendix
which is hereby incorporated in and expressly made a part of this Indenture. The
Exchange Securities, the Private Exchange Securities and the Trustee's
certificate of authentication shall be substantially in the form of Exhibit A,
which is hereby incorporated in and expressly made a part of this Indenture. The
Securities may have notations, legends or endorsements required by law, stock
exchange rule, agreements to which the Company is subject, if any, or usage
(provided that any such notation, legend or endorsement is in a form acceptable
to the Company). Each Security shall be dated the date of its authentication.
The terms of the Securities set forth in the Appendix and Exhibit A are part of
the terms of this Indenture.

                  SECTION 2.02.  EXECUTION AND AUTHENTICATION.  Two
Officers shall sign the Securities for the Company by manual
or facsimile signature.

                  If an Officer whose signature is on a Security no longer holds
that office at the time the Trustee authenti cates the Security, the Security
shall be valid neverthe less.

                  A Security shall not be valid until an authorized signatory of
the Trustee manually signs the certificate of authentication on the Security.
The signature shall be con clusive evidence that the Security has been
authenticated under this Indenture.

                  The Trustee shall authenticate and deliver Securities for
original issue upon a written order of the Company signed by two Officers or by
an Officer and either an Assistant Treasurer or an Assistant Secretary of the
Company. Such order shall specify the amount of the Securities to be
authenticated and the date on which the original issue of Securities is to be
authenticated. The aggregate principal amount of Securities outstanding at any

                                                                              26



time may not exceed that amount except as provided in
Section 2.06.

                  The Trustee may appoint an authenticating agent reasonably
acceptable to the Company to authenticate the Securities. Unless limited by the
terms of such appoint ment, an authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authen tication by such agent. An
authenticating agent has the same rights as any Registrar, Paying Agent or agent
for service of notices and demands.

                  SECTION 2.03. REGISTRAR AND PAYING AGENT. The Company shall
maintain an office or agency where Securities may be presented for registration
of transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent"). The Registrar
shall keep a register of the Secur ities and of their transfer and exchange. The
Company may have one or more co-registrars and one or more additional paying
agents. The term "Paying Agent" includes any addi tional paying agent.

                  The Company shall enter into an appropriate agency agreement
with any Registrar, Paying Agent or co-registrar not a party to this Indenture,
which shall incorporate the terms of the TIA. The agreement shall implement the
provi sions of this Indenture that relate to such agent. The Company shall
notify the Trustee of the name and address of any such agent. If the Company
fails to maintain a Regis trar or Paying Agent or to notify the Trustee as
provided in the previous sentence, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.07. The
Company or any of its domestically incorporated Wholly Owned Subsidiaries may
act as Paying Agent, Registrar, co-registrar or transfer agent.

                  The Company initially appoints the Trustee as Registrar and
Paying Agent in connection with the Securi ties.

                  SECTION 2.04. PAYING AGENT TO HOLD MONEY IN TRUST. Prior to
each due date of the principal and interest on any Security, the Company shall
deposit with the Paying Agent a sum sufficient to pay such principal and
interest when so becoming due. The Company shall require each Paying Agent
(other than the Trustee) to agree in writing that the Paying Agent shall hold in
trust for the benefit of Securityholders or the Trustee all money held by the
Paying


<PAGE>

                                                                              27



Agent for the payment of principal of or interest on the Securities and shall
notify the Trustee of any default by the Company in making any such payment. If
the Company or a Subsidiary acts as Paying Agent, it shall segregate the money
held by it as Paying Agent and hold it as a separate trust fund. The Company at
any time may require a Paying Agent to pay all money held by it to the Trustee
and to account for any funds disbursed by the Paying Agent. Upon complying with
this Section, the Paying Agent shall have no further liability for the money
delivered to the Trustee.

                  SECTION 2.05. SECURITYHOLDER LISTS. The Trustee shall preserve
in as current a form as is reasonably prac ticable the most recent list
available to it of the names and addresses of Securityholders. If the Trustee is
not the Registrar, the Company shall furnish to the Trustee, in writing at least
five Business Days before each interest payment date and at such other times as
the Trustee may request in writing, a list in such form and as of such date as
the Trustee may reasonably require of the names and addresses of
Securityholders.

                  SECTION 2.06. REPLACEMENT SECURITIES. If a mutilated Security
is surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies
any other reasonable requirements of the Trustee. If required by the Trustee or
the Company, such Holder shall furnish an indemnity bond sufficient in the
judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent, the Registrar and any co-registrar from any loss which any of them
may suffer if a Security is replaced. The Company and the Trustee may charge the
Holder for their expenses in replacing a Security.

                  Every replacement Security is an additional obligation of the
Company.

                  SECTION 2.07. OUTSTANDING SECURITIES. Securities outstanding
at any time are all Securities authenticated by the Trustee except for those
canceled by it, those delivered to it for cancelation and those described in
this Section as not outstanding. A Security does not cease to be outstand ing
because the Company or an Affiliate of the Company holds the Security.


<PAGE>

                                                                              28



                  If a Security is replaced pursuant to Section 2.06, it ceases
to be outstanding unless the Trustee and the Company receive proof satisfactory
to them that the replaced Security is held by a bona fide purchaser.

                  If the Paying Agent segregates and holds in trust, in
accordance with this Indenture, on a redemption date or maturity date money
sufficient to pay all principal and interest payable on that date with respect
to the Securities (or portions thereof) to be redeemed or maturing, as the case
may be, then on and after that date such Securities (or portions thereof) cease
to be outstanding and interest on them ceases to accrue.

                  SECTION 2.08. TEMPORARY SECURITIES. Until definitive
Securities are ready for delivery, the Company may prepare and the Trustee shall
authenticate temporary Securities. Temporary Securities shall be substantially
in the form of definitive Securities but may have variations that the Company
considers appropriate for temporary Securities. Without unreasonable delay, the
Company shall prepare and the Trustee shall authenticate definitive Securities
and deliver them in exchange for temporary Securities.

                  SECTION 2.09. CANCELATION. The Company at any time may deliver
Securities to the Trustee for cancelation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel and
destroy (subject to the record reten tion requirements of the Exchange Act) all
Securities surrendered for registration of transfer, exchange, payment or
cancelation and deliver a certificate of such destruction to the Company unless
the Company directs the Trustee to deliver canceled Securities to the Company.
The Company may not issue new Securities to replace Securities it has redeemed,
paid or delivered to the Trustee for cancelation.

                  SECTION 2.10. DEFAULTED INTEREST. If the Company defaults in a
payment of interest on the Securities, the Company shall pay defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful
manner. The Company may pay the defaulted interest to the persons who are
Securityholders on a subsequent special record date. The Company shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail to each
Securityholder a notice that states the special record date,


<PAGE>

                                                                              29



the payment date and the amount of defaulted interest to be
paid.

                  SECTION 2.11. CUSIP NUMBERS. The Company in issuing the
Securities 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, HOWEVER, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers.


                                    ARTICLE 3

                                   REDEMPTION

                  SECTION 3.01. NOTICES TO TRUSTEE. If the Company elects to
redeem Securities pursuant to paragraph 5 of the Securities or is required to
redeem Securities pursuant to paragraph 6 of the Securities, it shall notify the
Trustee in writing of the redemption date, the principal amount of Securities to
be redeemed and the paragraph of the Securities pursuant to which the redemption
will occur.

                  If the Company is required to redeem Securities pursuant to
paragraph 6 of the Securities, it may reduce the principal amount of Securities
required to be redeemed to the extent it is permitted a credit by the terms of
the Securities and it notifies the Trustee of the amount of the credit and the
basis for it. If the reduction is based on a credit for redeemed or canceled
Securities that the Company has not previously delivered to the Trustee for
cancelation, it shall deliver such Securities with the notice.

                  The Company shall give each notice to the Trustee provided for
in this Section at least 60 days before the redemption date unless the Trustee
consents to a shorter period. Such notice shall be accompanied by an Officers'
Certificate and an Opinion of Counsel from the Company to the effect that such
redemption will comply with the condi tions herein.

                  SECTION 3.02. SELECTION OF SECURITIES TO BE REDEEMED. If fewer
than all the Securities are to be redeemed, the Trustee shall select the
Securities to be redeemed pro rata or by lot or by a method that complies


<PAGE>

                                                                              30



with applicable legal and securities exchange requirements, if any, and that the
Trustee in its sole discretion shall deem to be fair and appropriate and in
accordance with methods generally used at the time of selection by fiduciaries
in similar circumstances. The Trustee shall make the selection from outstanding
Securities not previously called for redemption. The Trustee may select for
redemption portions of the principal of Securities that have denominations
larger than $1,000. Securities and portions of them the Trustee selects shall be
in amounts of $1,000 or a whole multiple of $1,000. Provisions of this Indenture
that apply to Securities called for redemption also apply to portions of
Securities called for redemption. The Trustee shall notify the Company promptly
of the Securities or portions of Securities to be redeemed.

                  SECTION 3.03. NOTICE OF REDEMPTION. At least 30 days but not
more than 60 days before a date for redemp tion of Securities, the Company shall
mail a notice of redemption by first-class mail to each Holder of Securities to

                  The notice shall identify the Securities to be redeemed and

         calculating such redemption price pursuant to this
         Indenture;

         are to be redeemed, the identification and principal

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

                  (7) the paragraph of the Securities pursuant to
         which the Securities called for redemption are being

                  The foregoing will constitute Events of Default whatever the
reason for any such Event of Default and whether it is voluntary or involuntary
or is effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or
governmental body.

                  The term "Bankruptcy Law" means Title 11, UNITED STATES CODE,
or any similar Federal or state law for the relief of debtors. The term
"Custodian" means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law.

                  A Default under clauses (4), (5) or (9) is not an Event of
Default until the Trustee or the holders of at least 25% in principal amount of
the outstanding Securities notify the Company of the Default and the Company
does not cure such Default within the time specified after receipt of such
notice. Such notice must specify the Default, demand that it be remedied and
state that such notice is a "Notice of Default".

                  The Company shall deliver to the Trustee, within 30 days after
the occurrence thereof, written notice in the form of an Officers' Certificate
of any Event of Default under clause (6), (10), (11) or (12) and any event which
with the giving of notice or the lapse of time would become

                                                                              47



an Event of Default under clause (4), (5) or (9), its status and what action the
Company is taking or proposes to take with respect thereto.

                  SECTION 6.02. ACCELERATION. If an Event of Default (other than
an Event of Default specified in Section 6.01(7) or (8) with respect to the
Company) occurs and is continuing, the Trustee by notice to the Company, or the
Holders of at least 25% in principal amount of the Securities then outstanding
by notice to the Company and the Trustee, may declare the principal of and
accrued but unpaid interest on all the Securities to be due and payable. Upon
such a declaration, such principal and interest shall be due and payable
immediately. If an Event of Default specified in Section 6.01(7) or (8) with
respect to the Company occurs, the principal of and interest on all the
Securities shall IPSO FACTO become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Securityholders.
The Holders of a majority in principal amount of the Securities by notice to the
Trustee may rescind an acceleration and its consequences if the rescission would
not conflict with any judgment or decree and if all existing Events of Default
have been cured or waived except nonpayment of principal or interest that has
become due solely because of acceleration. No such rescission shall affect any
subsequent Default or impair any right consequent thereto.

                  SECTION 6.03. OTHER REMEDIES. If an Event of Default occurs
and is continuing, the Trustee may pursue any available remedy to collect the
payment of principal of or interest on the Securities or to enforce the
performance of any provision of the Securities or this Indenture.

                  The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Securityholder 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 acquies cence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

                  SECTION 6.04. WAIVER OF PAST DEFAULTS. The Holders of a
majority in principal amount of the Securities by notice to the Trustee may
waive an existing Default and its consequences except (i) a Default in the
payment of the principal of or interest on a Security or (ii) a Default in
respect of a provision that under Section 9.02 cannot be amended without the
consent of each Securityholder affected.


<PAGE>

                                                                              48



When a Default is waived, it is deemed cured, but no such waiver shall extend to
any subsequent or other Default or impair any consequent right.

                  SECTION 6.05. CONTROL BY MAJORITY. The Holders of a majority
in principal amount of the Securities may direct the time, method and place of
conducting any proceed ing for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 7.01, that the Trustee determines is unduly prejudicial to
the rights of other Securityholders or would involve the Trustee in personal
liability; PROVIDED, HOWEVER, that the Trustee may take any other action deemed
proper by the Trustee that is not inconsistent with such direction. Prior to
taking any action hereunder, the Trustee shall be entitled to indemni fication
satisfactory to it in its sole discretion against all losses and expenses caused
by taking or not taking such action.

                  SECTION 6.06. LIMITATION ON SUITS. Except to enforce the right
to receive payment of principal, premium (if any) or interest when due, no
Securityholder may pursue any remedy with respect to this Indenture or the
Securities unless:

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

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

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

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

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

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

                  SECTION 6.07. RIGHTS OF HOLDERS TO RECEIVE PAYMENT.
Notwithstanding any other provision of this Inden ture, the right of any Holder
to receive payment of princi pal of and interest on the Securities held by such
Holder, on or after the respective due dates expressed in the Secu rities, 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(1) or (2) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust
against the Company for the whole amount then due and owing (together with
interest on any unpaid interest to the extent lawful) and the amounts provided
for in Section 7.07.

                  SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee
may file such proofs of claim and other papers or documents as may be necessary
or advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, its creditors or
its property and, unless prohibited by law or applicable regulations, may vote
on behalf of the Holders in any election of a trustee in bankruptcy or other
Person performing similar functions, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disburse ments and advances of the Trustee,
its agents and its counsel, and any other amounts due the Trustee under Section
7.07.

                  SECTION 6.10.  PRIORITIES.  If the Trustee col
lects any money or property pursuant to this Article 6, it
shall pay out the money or property in the following order:

                  FIRST:  to the Trustee for amounts due under
         Section 7.07;

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

                  THIRD:  to the Company.

                                                                              50



                  The Trustee may fix a record date and payment date for any
payment to Securityholders pursuant to this Section. At least 15 days before
such record date, the Company shall mail to each Securityholder and the Trustee
a notice that states the record date, the payment date and amount to be paid.

                  SECTION 6.11. UNDERTAKING FOR COSTS. In any suit for the
enforcement of any right or remedy under this Inden ture or in any suit against
the Trustee for any action taken or omitted by it as Trustee, a court in its
discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including rea sonable attorneys' fees, against any
party litigant in the suit, having due regard to the merits and good faith of
the claims or defenses made by the party litigant. This Section does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit
by Holders of more than 10% in principal amount of the Securities.

                  SECTION 6.12. WAIVER OF STAY OR EXTENSION LAWS. The Company
(to the extent it may lawfully do so) shall not at any time insist upon, or
plead, or in any manner whatso ever claim or take the benefit or advantage of,
any stay or extension law wherever enacted, now or at any time hereafter in
force, which may affect the covenants or the performance of this Indenture; and
the Company (to the extent that it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law, and shall not hinder, delay or impede
the execution of any power herein granted to the Trustee, but shall suffer and
permit the execution of every such power as though no such law had been enacted.

         Trustee; and

         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 require ments
         of this Indenture and the Security Agreements. However, the Trustee
         shall examine the certificates and opinions to determine whether or not

         Trustee was negligent in ascertaining the pertinent facts; and

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

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

                  (h) Every provision of this Indenture or of the Security
Agreements relating to the conduct or affecting the liability of or affording

would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or
co-paying agent may do the same with like rights. However, the Trustee must
comply with Sections 7.10 and 7.11.

                  SECTION 7.04. TRUSTEE'S DISCLAIMER. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture, the Security Agreements or the Securities, it shall not be
accountable for the Company's use of the proceeds from the Securities, and it
shall not be responsible for any statement of the Company in this Indenture, the
Security Agreements or in any document issued in connection with the sale of the
Securities or in the Securities other than the Trustee's certificate of
authentication.

                  SECTION 7.05. NOTICE OF DEFAULTS. If a Default occurs and is
continuing and if it is known to the Trustee, the Trustee shall mail to each
Securityholder notice of the Default within 90 days after it occurs. Except in
the case of a Default in payment of principal of or interest on any Security
(including payments pursuant to the redemption provisions of such Security, if
any), the Trustee may withhold the notice if and so long as a committee of its
Trust Officers in good faith determines that withholding the notice is in the
interests of Securityholders.

                  SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS. As promptly as
practicable after each May 15 beginning with the May 15 following the date of
this Indenture, and in any event prior to July 31 in each year, the Trustee
shall mail to each Securityholder a brief report dated as of May 15 that
complies with TIA ss. 313(a). The Trustee also shall comply with TIA ss. 313(b).

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

                  SECTION 7.07. COMPENSATION AND INDEMNITY. (a) The Company
shall pay to the Trustee from time to time reasonable compensation for its
services. The Trustee's compensation shall not be limited by any law on
compensation of fiduciaries or a trustee of an express trust. The Company shall
reimburse the Trustee upon request for all reasonable out-of-pocket expenses
incurred or made by it, including costs of collection, in addition to the


<PAGE>

                                                                              54



compensation for its services. Such expenses shall include the reasonable
compensation and expenses, disbursements and advances of the Trustee's agents,
counsel, accountants and experts.

                  (b) The Company shall indemnify the Trustee and hold it
harmless from and against any and all loss, liability or expense (including
attorneys' fees) incurred by it in connection with the administration of this
trust and the performance of its duties hereunder and under the Security
Agreements. 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 may have separate counsel and the Company shall pay the
fees and expenses of such counsel. The Company need not reimburse any expense or
indemnify against any loss, liability or expense incurred by the Trustee through
the Trustee's own wilful misconduct, negligence or bad faith.

                  (c) In addition to, but without duplication of, its
obligations under subsection (b) above, the Company shall indemnify and hold
harmless the Trustee and the Securityholders from and against any and all
losses, damages and expenses incurred by the Trustee and the Securityholders as
a result of any environmental damage resulting from the operation of any Vessel.

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

                  (e) The Company's payment obligations pursuant to this Section
shall survive the discharge of this Indenture. When the Trustee incurs expenses
after the occurrence of a Default specified in Section 6.01(7) or (8) with
respect to the Company, the expenses are intended to constitute expenses of
administration under the Bankruptcy Law.

                  SECTION 7.08. REPLACEMENT OF TRUSTEE. The Trustee may resign
at any time by so notifying the Company. The Holders of a majority in principal
amount of the Secur ities then outstanding may remove the Trustee by so
notifying the Trustee and may appoint a successor Trustee.
The Company shall remove the Trustee if:

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


<PAGE>

                                                                              55



                  (2) the Trustee is adjudged bankrupt or insolvent;

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

                  (4) the Trustee otherwise becomes incapable of
         acting.

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

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.07.

                  If a successor Trustee does not take office within 60 days
after the retiring Trustee resigns or is removed, the retiring Trustee or the
Holders of 10% in principal amount of the Securities may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

                  If the Trustee fails to comply with Section 7.10, any
Securityholder may petition any court of competent jurisdiction for the removal
of the Trustee and the appoint ment of a successor Trustee.

                  Notwithstanding the replacement of the Trustee pursuant to
this Section, the Company's obligations under Section 7.07 shall continue for
the benefit of the retiring Trustee.

                  SECTION 7.09. SUCCESSOR TRUSTEE BY MERGER. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

                                                                              56



                  In case at the time such successor or successors by merger,
conversion or consolidation to the Trustee shall succeed to the trusts created
by this Indenture any of the Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificate of the Trustee shall have.

                  SECTION 7.10. ELIGIBILITY; DISQUALIFICATION. The Trustee shall
at all times satisfy the requirements of TIA ss. 310(a). The Trustee shall have
a combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition. The Trustee shall comply with
TIAss. 310(b); PROVIDED, HOWEVER, that there shall be excluded from the
operation of TIAss. 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of
the Company are out standing if the requirements for such exclusion set forth in
TIAss. 310(b)(1) are met.

                  SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST
COMPANY. The Trustee shall comply with TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been
removed shalL be subject to TIA ss. 311(a) to the extent indicated.

                  SECTION 7.12. NOT ACTING IN INDIVIDUAL CAPACITY. Except as
otherwise provided in this Indenture, the Trustee acts hereunder solely as
trustee as herein provided and not in its individual capacity, and all persons,
other than the Securityholders as provided in this Indenture, having any claim
against the Trustee by reason of the transactions contemplated hereby shall,
subject to priorities of payment as herein provided, look only to the Collateral
for payment or satisfaction thereof.

Trustee funds suffi cient to pay at maturity or upon redemption all outstanding
Securities, including interest thereon to maturity or such redemption date
(other than Securities replaced pursuant to Section 2.06), and if in either case
the Company pays all other sums payable hereunder by the Company, then this
Indenture and the Security Agreements shall, subject to Sections 8.01(c), cease
to be of further effect. The Trustee shall acknowledge satisfaction and
discharge of this Indenture and the Security Agreements on demand of the Company
accompanied by an Officers' Certificate and an Opinion of Counsel and at the
cost and expense of the Company.

                  (b) Subject to Sections 8.01(c) and 8.02, the Company at any

obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.07 and 7.08 and in
this Article 8 shall survive until the Securities have been paid in full.

         when due on all the Securities to maturity or redemption, as the case
         may be;

                  (3) 123 days pass after the deposit is made and during the

         of Counsel shall confirm that, the Securityholders will not recognize
         income, gain or loss for Federal income tax purposes as a result of
         such defeasance and will be subject to Federal income tax on the same

         the case if such defeasance had not occurred;

                  (7) in the case of the covenant defeasance option, the Company

                  (8) the Company delivers to the Trustee a letter from each of
         the Rating Agencies and which such Rating Agency confirms that the
         exercise of such legal defeasance option or covenant defeasance

         Securities; and

                  (9) the Company delivers to the Trustee an Offi cers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent to the defeasance and discharge of the Securities as

unable to apply any money or U.S. Government Obligations in accordance with this

apply all such money or U.S. Government Obligations in accordance with this
Article 8; PROVIDED, HOWEVER, that, if the Company has made any payment of

         surrender any right or power herein conferred upon the
         Company;

                  (7) to comply with any requirements of the SEC in connection
         with qualifying, or maintaining the qualification of, this Indenture
         under the TIA; or

                  (8) to make any change that does not adversely
         affect the rights of any Securityholder.

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

                  SECTION 9.02.  WITH CONSENT OF HOLDERS.  The
Company, the Guarantors and the Trustee may amend this

                                                                              62



Indenture or the Securities without notice to any Securityholder but with the
written consent of the Holders of at least a majority in principal amount of the
Securities (including consents obtained in connection with a tender offer or
exchange for the Securities). However, without the consent of each
Securityholder affected thereby, an amendment may not:

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

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

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

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

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

                  (6) make any changes in the Security Agreements or in Articles
         10 or 11 that adversely affect the Holders or would terminate the Lien
         of this Indenture or any Security Agreement on any property subject
         thereto or deprive the Holder of the security afforded by the Lien of
         this Indenture or the Security Agreements;

                  (7) make any change in Section 6.04 or 6.07 or the
         second sentence of this Section; or

                  (8) make any change in any Guarantee that would
         adversely affect the Securityholders.

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

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

                  SECTION 9.03. COMPLIANCE WITH TRUST INDENTURE ACT. Every
amendment to this Indenture, the Security Agreements or the Securities shall
comply with the TIA as then in effect.

                  SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS AND WAIVERS. A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subse quent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subse quent Holder may revoke the consent or waiver as to such
Holder's Security or portion of the Security if the Trustee receives the notice
of revocation before the date the amendment or waiver becomes effective. After
an amendment or waiver becomes effective, it shall bind every Security holder.
An amendment or waiver becomes effective upon the execution of such amendment or
waiver by the Trustee.

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

                  SECTION 9.05. NOTATION ON OR EXCHANGE OF SECURI TIES. If an
amendment changes the terms of a Security, the Trustee may require the Holder of
the Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder. Alternatively, if the Company or the Trustee so determines, the Company
in exchange for the Security shall issue and the Trustee shall authenticate a
new Security that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such
amendment.

                  SECTION 9.06. TRUSTEE TO SIGN AMENDMENTS. The Trustee shall
sign any amendment authorized pursuant to this Article 9 if the amendment does
not adversely affect the rights, duties, liabilities or immunities of the
Trustee.


<PAGE>

                                                                              64



If it does, the Trustee may but need not sign it. In sign ing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Section 7.01) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that such
amendment is authorized or permit ted by this Indenture.

                  SECTION 9.07. PAYMENT FOR CONSENT. Neither the Company nor any
Affiliate of the Company shall, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
for or as an inducement to any consent, waiver or amendment of any of the terms
or provisions of this Indenture or the Securities unless such consideration is
offered to be paid to all Holders that so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.


                                   ARTICLE 10

                                   GUARANTEES

                  SECTION 10.01. GUARANTEES. Each Guarantor hereby
unconditionally and irrevocably guarantees, jointly and severally, to each
Holder and to the Trustee and its successors and assigns (a) the full and
punctual payment of principal of and interest on the Securities when due,
whether at maturity, by acceleration, by redemption, by required repurchase or
otherwise, and all other monetary obligations of the Company and the other
Guarantors under this Indenture and the Securities and of the Owners under the
Security Agreements and (b) the full and punctual performance within applicable
grace periods of all other obligations of the Company and the other Guarantors
under this Indenture, the Security Agreements and the Securities (all the
foregoing being hereinafter collectively called the "Obligations"). Each
Guarantor further agrees that the Obligations may be extended or renewed, in
whole or in part, without notice or further assent from such Guarantor and that
such Guarantor will remain bound under this Article 10 notwithstanding any
extension or renewal of any Obligation.

                  Each Guarantor waives presentation to, demand of, payment from
and protest to the Company of any of the Obligations and also waives notice of
protest for nonpayment. Each Guarantor waives notice of any default under the
Securities or the Obligations. The obligations of each Guarantor hereunder shall
not be affected by (a) the


<PAGE>

                                                                              65



failure of any Holder or the Trustee to assert any claim or demand or to enforce
any right or remedy against the Company or any other Person under this
Indenture, the Security Agreements, the Securities or any other agreement or
otherwise; (b) any extension or renewal of any thereof; (c) any rescission,
waiver, amendment or modification of any of the terms or provisions of this
Indenture, the Security Agreements, the Securities or any other agreement; (d)
the release of any security held by any Holder or the Trustee for the
Obligations or any of them; (e) the failure of any Holder or the Trustee to
exercise any right or remedy against any other guarantor of the Obligations; or
(f) subject to Section 10.06, any change in the ownership of such Guarantor.

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

                  Except as expressly set forth in Sections 8.01(b), 10.02 and
10.06, the obligations of each Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including any
claim of waiver, release, surrender, alteration or compromise, and shall not be
subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
Obligations or otherwise. Without limiting the generality of the foregoing, the
obligations of each Guarantor herein shall not be discharged or impaired or
otherwise affected by the failure of any Holder or the Trustee to assert any
claim or demand or to enforce any remedy under this Indenture, the Security
Agreements, the Securities or any other agreement, by any waiver or modification
of any thereof, by any default, failure or delay, willful or otherwise, in the
performance of the obligations, or by any other act or thing or omission or
delay to do any other act or thing which may or might in any manner or to any
extent vary the risk of such Guarantor or would otherwise operate as a discharge
of such Guarantor as a matter of law or equity.

                  Each Guarantor further agrees that its Guarantee herein shall
continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of principal of or interest on any Obligation is
rescinded or must otherwise be restored by any Holder or the


<PAGE>

                                                                              66



Trustee upon the bankruptcy or reorganization of the Company or otherwise.

                  In furtherance of the foregoing and not in limitation of any
other right which any Holder or the Trustee has at law or in equity against any
Guarantor by virtue hereof, upon the failure of the Company to pay the principal
of or interest on any Obligation when and as the same shall become due, whether
at maturity, by acceleration, by redemption or otherwise, or to perform or
comply with any other Obligation, each Guarantor hereby promises to and will,
upon receipt of written demand by the Trustee, forthwith pay, or cause to be
paid, in cash, to the Holders or the Trustee an amount equal to the sum of (i)
the unpaid amount of such Obligations, (ii) accrued and unpaid interest on such
Obligations (but only to the extent not prohibited by law) and (iii) all other
monetary Obligations of the Company or the Guarantors to the Holders and the
Trustee.

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

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

                  SECTION 10.02. LIMITATION ON LIABILITY. Any term or provision
of this Indenture to the contrary notwith standing, the maximum aggregate amount
of the Obligations guaranteed hereunder by any Owner shall not exceed the
maximum amount that can be hereby guaranteed without rendering this Indenture,
as it relates to such Owner, voidable under applicable law relating to
fraudulent conveyance or fraudulent transfer or similar laws affecting the
rights of creditors generally.

                  SECTION 10.03. SUCCESSORS AND ASSIGNS. This Article 10 shall
be binding upon each Guarantor and its successors and assigns and shall enure to
the benefit of the


<PAGE>

                                                                              67



successors and assigns of the Trustee and the Holders and, in the event of any
transfer or assignment of rights by any Holder or the Trustee, the rights and
privileges conferred upon that party in this Indenture, in the Security
Agreements and in the Securities shall automatically extend to and be vested in
such transferee or assignee, all subject to the terms and conditions of this
Indenture.

                  SECTION 10.04. NO WAIVER. Neither a failure nor a delay on the
part of either the Trustee or the Holders in exercising any right, power or
privilege under this Article 10 shall operate as a waiver thereof, nor shall a
single or partial exercise thereof preclude any other or further exercise of any
right, power or privilege. The rights, remedies and benefits of the Trustee and
the Holders herein expressly specified are cumulative and not exclusive of any
other rights, remedies or benefits which either may have under this Article 10
at law, in equity, by statute or otherwise.

                  SECTION 10.05. MODIFICATION. No modification, amendment or
waiver of any provision of this Article 10, nor the consent to any departure by
any Guarantor therefrom, shall in any event be effective unless the same shall
be in writing and signed by the Trustee, and then such waiver or consent shall
be effective only in the specific instance and for the purpose for which given.
No notice to or demand on any Guarantor in any case shall entitle such Guarantor
to any other or further notice or demand in the same, similar or other
circumstances.

                  SECTION 10.06. RELEASE OF GUARANTOR. Upon the sale or other
disposition (including by way of consolidation or merger) of an Owner or the
sale or disposition of all or substantially all the assets of such Owner (in
each case other than to the Company or an Affiliate of the Company), such Owner
shall be deemed released from all obligations under this Article 10 without any
further action required on the part of the Trustee or any Holder. At the request
of the Company and upon receipt of an Officers' Certificate, the Trustee shall
execute and deliver an appropriate instrument evidencing such release.

                               SECURITY AGREEMENTS

                  SECTION 11.01. COLLATERAL AND SECURITY AGREEMENTS. (a) To
secure the due and punctual payment of the Obligations, the Company, the Owners
and the Trustee have entered into the Intercreditor Agreement and have entered
or, under the circumstances described in the Intercreditor Agreement, will
enter, into the Security Agreements. The Trustee and the Company hereby
acknowledge and agree that the Collateral Agent holds the Collateral in trust
for the benefit of the Trustee and the Holders, in each case pursuant to the
terms of the Security Agreements. Each Holder, by accepting a Security, shall be
deemed to have agreed to all the terms and provisions of the Security
Agreements.

                  (b) As among the Holders, the Collateral shall be held for the
equal and ratable benefit of such holders without preference, priority or
distinction of any thereof over any other.

                  SECTION 11.02. RECORDING; ANNUAL OPINIONS. (a) The Company and
the Owners will take or cause to be taken all action required to maintain,
preserve and protect the Lien on the Collateral granted by the Security

and the Trustee under this Indenture and the Security Agreements to the
Collateral.

                  The Company and the Owners will from time to time promptly pay
and discharge all recording or filing fees, charges and taxes relating to the
filing or registration of this Indenture and the Security Agreements, any
amendments thereto and any other instruments of further assurance.

                  (b)  The Company and the Owners shall furnish to

         Indenture and the assignment of the Collateral intended to be made by

         filing) to the extent necessary to make effective the Lien created by
         such Security Agreements and reciting the details of such action, and

         to maintain such notice (other than as stated in such opinion), and
         further stating that all statements have been executed and filed (or
         proper provision has been made for such filing) that are necessary
         fully to preserve and protect the rights of the Holders and the Trustee
         with respect to the Lien under this Indenture and such Security
         Agreements, or (b) to the effect that, in the opinion of such counsel,
         no such action is necessary to perfect such Lien; and

         furniture, apparatus, tools or implements, materials or supplies or
         other similar property subject to the Lien of this Indenture and the
         Security Agreements, which may have become worn out or obsolete, not
         exceeding in aggregate value in any one calendar year $1,000,000, or
         which may constitute an Incidental Asset, upon substituting for the
         same other machinery, equipment, furniture, apparatus, tools or
         implements, materials or supplies or other similar property not
         necessarily of the same character but of at least equal value to the
         Company as, and costing not less than the amount realized from, the
         Collateral disposed of, which shall forthwith become, without further
         action, subject to the Lien of this Indenture and the Security
         Agreements;

                  (ii) abandon, terminate, cancel, release or make alterations
         in or substitutions of any contracts subject to the Lien of this
         Indenture and any of the Security Agreements; PROVIDED, HOWEVER, that
         any altered or substituted contracts shall forthwith, without further
         action, be subject to the Lien of this Indenture and the Security
         Agreements to the same extent as those previously existing;

                  (iii) surrender or modify any franchise, license or permit
         subject to the Lien of this Indenture and any of the Security
         Agreements which it may own or under which it may be operating;
         PROVIDED, HOWEVER, that, after the surrender or modification of any
         such franchise, license or permit, the Company or the applicable Owner
         shall still, in the reasonable opinion of the Board of Directors of the
         Company, be entitled, under some other or without any franchise,
         license or permit, to conduct its business as it was operating
         immediately prior to such surrender or modification;

                  (iv) alter, repair, replace and add to its plants, structures,
         machinery, systems, equipment, fixtures and appurtenances; PROVIDED,
         HOWEVER, that such alteration, repair or replacement shall comply with

         opinion of the Board of Directors, be prejudicial to the interests of
         the Holders; or


<PAGE>

                                                                              71



                  (v) demolish, dismantle, tear down or scrap any portion of the
         Collateral (other than a Vessel), if in the good faith opinion of the
         Board of Directors, as evidenced by a Board Resolution, such
         demolition, dis mantling, tearing down or scrapping is in the best
         interests of the Company and the fair market value and utility of the
         Collateral as an entirety, and the security for the Securities, will
         not thereby be impaired.

                  (b) In the event that the Company or an Owner has sold,
exchanged or otherwise disposed of or proposes to sell, exchange or otherwise
dispose of any portion of the Collateral which under the provisions of this
Section 11.03 may be sold, exchanged or otherwise disposed of by the Company
without any release or consent of the Trustee or the Collateral Agent, and the
Company requests the Trustee to furnish a written disclaimer, release or
quitclaim of any interest in such property under this Indenture and the Security
Agreements, the Trustee shall execute such an instrument upon delivery to the
Trustee of (i) an Officers' Certificate by the Company reciting the sale,
exchange or other disposition made or proposed to be made and describing in
reasonable detail the property affected thereby, and stating that such property
is property which by the provisions of this Section 11.03 may be sold, exchanged
or otherwise disposed of or dealt with by the Company without any release or
consent of the Trustee and (ii) an Opinion of Counsel stating that the sale,
exchange or other disposition made or proposed to be made was duly taken by the
Company or the Owner in conformity with a designated subsection of Section
11.03(a) and that the execution of such written disclaimer, release or quitclaim
is appropriate to confirm the propriety of such sale, disposition or other
disposition under this Section 11.03.

                  SECTION 11.04. RELEASE OF COLLATERAL. Collateral may be
released from the security interest created by the Security Agreements at any
time or from time to time in accordance with the provisions of the Security
Agreements. The release of any Collateral from the terms hereof and of the
Security Agreements or the release of, in whole or in part, the Liens created by
the Security Agreements, will not be deemed to impair the Lien on the Collateral
in contravention of the provisions hereof if and to the extent the Collateral or
Liens are released pursuant to the applicable Security Agreements and pursuant
to the terms of this Article 11. The Trustee and each of the Holders acknowledge
that a release of Collateral or a Lien strictly in accordance with the terms of

of this Article 11 will not be deemed for any purpose to be an impairment of the
Lien on the Collateral in contravention of the terms of this Indenture. To the
extent applicable, the Company and each obligor on the Securities shall cause
ss. 314(d) of the TIA relating to the release of property or securities from the
Lien hereof and of the Security Agreements to be complied with. Any certificate
or opinion required by ss. 314(d) of the TIA may be made by an officer of the
Company, except in cases which ss. 314(d) of the TIA requires that such
certificate or opinion be made by an independent person.

                  SECTION 11.05. PERMITTED RELEASES NOT TO IMPAIR LIEN; TRUST
INDENTURE ACT REQUIREMENTS. The release of any Collateral from the terms hereof
and of the Security Agreements or the release of, in whole or in part, the Liens
created by the Security Agreements, will not be deemed to impair the Lien on the
Collateral in contravention of the provisions hereof if and to the extent the
Collateral or Liens are released pursuant to the applicable Security Agreements
and pursuant to the terms of this Article 11. The Trustee and each of the
Holders acknowledge that a release of Collateral or a Lien strictly in
accordance with the terms of the Security Agreements and of this Article 11 will
not be deemed for any purpose to be an impairment of the Lien on the Collateral
in contravention of the terms of this Indenture. To the extent applicable, the
Company and each obligor on the Securities shall cause ss. 314(d) of the TIA
relating to the release of property or securities from the Lien hereof and of
the Security Agreements to be complied with. Any certificate or opinion required
by ss. 314(d) of the TIA may be made by an officer of the Company, except in
cases which ss. 314(d) of the TIA requires that such certificate or opinion be
made by an independent person.

                  SECTION 11.06. SUITS TO PROTECT THE COLLATERAL. Subject to the
provisions of the Security Agreements, the Trustee shall have power to institute
and to maintain such suits and proceedings as it may deem expedient to prevent
any impairment of the Collateral by any acts which may be unlawful or in
violation of any of the Security Agreements or this Indenture, and such suits
and proceedings as the Trustee, in its sole discretion, may deem expedient to
preserve or protect its interests and the interests of the Holders in the
Collateral (including power to institute and maintain suits or proceedings to
restrain the enforcement of or compliance with any legislative or other
governmental enactment, rule or order that may be unconstitutional or otherwise
invalid if the enforcement of, or compliance with,

                                                                              73



such enactment, rule or order would impair the Lien on the Collateral or be
prejudicial to the interests of the Holders or the Trustee).

                  SECTION 11.07. PURCHASER PROTECTED. In no event shall any
purchaser in good faith of any property purported to be released hereunder be
bound to ascertain the authority of the Trustee or the Collateral Agent to
execute the release or to inquire as to the satisfaction of any conditions
required by the provisions hereof or of the Security Agreements for the exercise
of such authority or to see to the application of any consideration given by
such purchaser or other transferee; nor shall any purchaser or other transferee
of any property or rights permitted by this Article 11 to be sold be under
obligation to ascertain or inquire into the authority of the Company or the
applicable Owner to make any such sale or other transfer.

                  SECTION 11.08. POWERS EXERCISABLE BY RECEIVER OR TRUSTEE. In
case the Collateral shall be in the possession of a receiver or trustee,
lawfully appointed, the powers conferred in this Article 11 upon the Company or
an Owner with respect to the release, sale or other disposition of such property
may be exercised by such receiver or trustee, and an instrument signed by such
receiver or trustee shall be deemed the equivalent of any similar instrument of
the Company or an Owner or of any officer or officers thereof required by the
provisions of this Article 11; and if the Trustee or the Collateral Agent shall
be in the possession of the Collateral under any provision of this Indenture,
then such powers may be exercised by the Trustee or the Collateral Agent.

                  SECTION 11.09. DISPOSITION OF OBLIGATIONS RECEIVED. All
purchase money and other obligations received by the Collateral Agent under this
Article 11 shall be held by the Trustee as a part of the Collateral. Upon
payment in cash or cash equivalents by or on behalf of the Company to the
Collateral Agent of the entire unpaid principal amount of any such obligation,
the Trustee shall or the Collateral Agent release and transfer such obligation
and any mortgage securing the same upon receipt of any documentation that the
Trustee may reasonably require. Any cash or cash equivalents received by the
Collateral Agent in respect of the principal of any such obligations shall be
held by the Collateral Agent as Trust Moneys under the Intercreditor Agreement
subject to application as therein provided and as provided in the Security
Agreements. All interest and other income on any such obligations, when received
by the

Collateral Agent shall be held and applied in accordance with the Intercreditor
Agreement.

                  SECTION 11.10. DETERMINATIONS RELATING TO COLLATERAL. In the
event (i) the Trustee shall receive any written request from the Company or an
Owner under any Security Agreement for consent or approval with respect to any
matter or thing relating to any Collateral or the Company's or an Owner's
obligations with respect thereto or (ii) there shall be due to or from the
Trustee under the provisions of any Security Agreement any material performance
or the delivery of any material instrument or (iii) the Trustee shall become
aware of any material nonperformance by the Company or an Owner of any covenant
or any material breach of any representation or warranty of the Company or an
Owner set forth in any Security Agreement, then, in each such event, the Trustee
shall be entitled to hire, at the sole reasonable cost and expense of the
Company, experts, consultants, agents and attorneys to advise the Trustee on the
manner in which the Trustee should respond, to such request or render any
requested performance or response to such nonperformance or breach. The Trustee
shall be fully protected in accordance with Article 7 hereof in the taking of
any action recommended or approved by any such expert, consultant, agent or
attorney and by indemnification provided in accordance with Section 6.05 and
other sections of this Indenture if such action is agreed to by Holders of a
majority in principal amount of the Securities pursuant to Section 6.05 and, the
Trustee may, in its sole discretion, prior to taking such action if such action
could subject it to environmental liabilities or taxation, require (i) direction
from the Holders of a majority in principal amount of the Securities in
accordance with Section 6.05 hereof and (ii) indemnification in accordance with
Section 6.05.

                  SECTION 11.11. RELEASE UPON TERMINATION OF THE COMPANY'S
OBLIGATIONS. In the event that the Company delivers an Officers' Certificate
certifying that all the obligations under this Indenture, the Securities and the
Security Agreements have been satisfied and discharged by complying with the
provisions of Article 8 or by the payment in full of the Company's obligations
under the Securities, this Indenture and the Security Agreements, the Trustee
shall deliver to the Company a notice stating that the Trustee, on behalf of the
Holders, disclaims and gives up any and all rights it has in or to the
Collateral, and any rights it has under the Security Agreements.

this Indenture, the Securities or the Security Agreements that may be instituted

brought by the Trustee (whether in its individual capacity or in its capacity as
Trustee hereunder), and acknowledges that CPLLC has accepted such designation,
(ii) submits to the jurisdiction of any such court in any such suit or
proceeding, and (iii) agrees that service of process upon CPLLC and written
notice of said service to the Company or the applicable Guarantor, shall be
deemed in every respect effective service of process upon the Company or such
Guarantor, as the case may be, in any such suit or proceeding. The Company and
each of the Guarantors further agree to take any and all action, including the
execution and filing of any and all such documents and instruments, as may be
necessary to continue such designation and appointment of CPLLC in full force
and effect so long as this Indenture shall be in full force and effect.

suit, action or proceeding arising out of or relating to this Indenture, the
Security Agreements or the Securities in any federal or state court in the State
of New York, Borough of Manhattan. The Company and each of the Guarantors hereto
hereby irrevocably waives, to the fullest extent permitted

by law, the defense of an inconvenient forum to the maintenance of such action
or proceeding in any such court.

                  To the extent either the Company or any of the Guarantors has
or hereafter may acquire any immunity from jurisdiction of any court or from any
legal process (whether through service of notice, attachment prior to judgment,
attachment in aid of execution, execution or otherwise) with respect to itself
or its property, it hereby irrevocably waives such immunity in Securities and
the Security Agreements, to the extent permitted by law.


                  IN WITNESS WHEREOF, the parties have caused this Indenture to
be duly executed as of the date first written above.

         such exchange was made in reliance on Rule 144 (such certification to
         be in the form set forth on the reverse of the Security).

         Exchange Securities during the period of the effectiveness of a Shelf
         Registration Statement with respect to such Initial Securities or
         Private Exchange Securities, as the case may be, all requirements
         pertaining to legends on such Initial Security or such Private Exchange
         Security will cease to apply, the requirements that any such Initial
         Security or such Private Exchange Security issued to certain Holders be

         Securities in such Registered Exchange Offer.

                  (v) Upon the consummation of a Private Exchange with respect
         to the Initial Securities pursuant to which Holders of such Initial

the Trustee. At any time prior to such cancelation, if any beneficial interest
in a Global Security is exchanged for certificated Securities, redeemed,
repurchased or canceled, the principal amount of Securities represented by such
Global Security shall be reduced and an adjustment shall be made on the books
and records of the Trustee (if it is then the Securities Custodian for such
Global Security) with respect to such Global Security, by the Trustee or the
Securities Custodian, to reflect such reduction.

no responsibility or obligation to any beneficial owner of a Global Security, a
member of, or a participant in the Depositary or other Person with respect to

                   [FORM OF REVERSE SIDE OF INITIAL SECURITY]


                 12% Second Priority Ship Mortgage Note Due 2007


                  1.  INTEREST

                  NAVIGATOR GAS TRANSPORT PLC, an Isle of Man public limited
company (such corporation, and its succes ors and assigns under the Indenture
hereinafter referred to, being herein called the "Company"), promises to pay
interest on the principal amount of this Security at the rate per annum shown
above; PROVIDED, HOWEVER, that if a Registration Default (as defined in the
Registration Rights Agreement) occurs, additional interest will accrue on this
Security at a rate of 0.50% per annum from and including the date on which any
such Registration Default shall occur to but excluding the date on which all
Registration Defaults have been cured. The Company will pay interest in cash
semiannually on June 30 and December 31 of each year, commencing December 31,
1997, except that at the option of the Company, on any Interest Payment Date
following the delivery of the first Vessel, to the extent cash available for
distribution to Holders of Securities on such date is insufficient to pay all
accrued and unpaid interest on the Securities on such date, the Company may pay
such interest by issuing additional Securities having an aggregate principal
amount equal to the amount of such deficiency, PROVIDED that the Company may not
issue more than $20,900,000 aggregate principal amount of such additional
Securities. Interest on the Securities will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from August 7,
1997. Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

                  2.  METHOD OF PAYMENT

                  The Company will pay interest on the Securities (except
defaulted interest) to the Persons who are registered holders of Securities at
the close of business on the June 15 or December 15 next preceding the interest
payment date even if Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying
Agent to collect principal payments. The Company will pay principal and interest
in money of the United States that at the time of payment is legal tender for


<PAGE>

                                                                               5



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

                  3.  PAYING AGENT AND REGISTRAR

                  Initially, The Chase Manhattan Bank, a New York banking
corporation ("Trustee"), will act as Paying Agent and Registrar. The Company may
appoint and change any Paying Agent, Registrar or co-registrar without notice.
The Company or any of its domestically incorporated Wholly Owned Subsidiaries
may act as Paying Agent, Registrar or co-registrar.

                  4.  INDENTURE

                  The Company issued the Securities under an Indenture dated as
of August 1, 1997 ("Indenture"), among the Company, Holdings, the Guarantors and
the Trustee. The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as in effect on the date of the Indenture
(the "Act"). Terms defined in the Indenture and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
such terms, and Securityholders are referred to the Indenture and the Act for a
statement of those terms.

                  The Securities are general secured obligations of the Company
initially limited to $87,000,000 aggregate principal amount (subject to Section
2.06 of the Indenture and subject to the issuance of up to $20,900,000 aggregate
principal amount of Securities under the circumstances described in paragraph 1
above). The Indenture limits (i) the incurrence of additional debt by the
Company and the Owner, (ii) the payment of dividends on capital stock of the
Company and the purchase, redemption or retirement of capital stock or


<PAGE>

subordinated indebtedness, (iii) investments, (iv) certain liens and
sale/leaseback transactions, (v) certain transactions with affiliates, (vi)
sales of assets, (vii) the issuance or sale of capital stock of subsidiaries and
(viii) certain consolidations, mergers and transfers of assets. The Indenture
also prohibits certain restrictions on distributions from the Owners.

                  5. OPTIONAL REDEMPTION

                  Except as set forth in the next two paragraphs, the Securities
may not be redeemed prior to June 30, 2002. On and after that date, the Company
may redeem the Securities in whole at any time or in part from time to time at
the following redemption prices (expressed in percentages of principal amount),
plus accrued interest to the redemption date (subject to the right of Holders of

             2005 and thereafter  . . . . . . . . . . .  100.000

                  If, as a result of any change in or any amendment to the laws,
regulations or published tax rulings of the Isle of Man or any Successor
Jurisdiction, or of any political subdivision or taxing authority thereof or
therein, or any change in the official administration, application or
interpretation of such laws, regulations or published tax rulings either

administration, application or interpretation shall not have been available to
the public prior to such issue date and is notified to the Company or the
relevant Owners, as the case may be, on or after such issue date, it is
determined by the Company or the relevant Owners, as the case may be, that the
Company or the relevant Owners, as the case may be, would be required to pay,
any Additional Amounts pursuant to the Indenture or the terms of any Security in
respect of interest on the next succeeding Interest Payment Date (assuming, in
the case of the Owners, that a payment in respect of such interest were required
to be made by the relevant Owners under the Guarantees on such Interest Payment
Date), and that such obligation cannot be

                                                                               7

available to it, the Company or the relevant Owners, as the case may be, may, at
its option, redeem all (but not less than all) the Securities in respect of
which such Additional Amounts would be so payable at any time, at a redemption
price equal to 100% of the principal amount thereof plus accrued interest to the
date fixed for redemption; PROVIDED, HOWEVER, that (a) no such notice of
redemption may be given earlier than 60 days prior to the earliest date on which
the Company or the relevant Owners, as the case may be, would be obligated, or
is substantially likely to be obligated, to pay such Additional Amounts were a
payment in respect of the Securities or the Guarantees, as the case may be, then
due, and (b) at the time any such redemption notice is given, such obligation,
or substantial likelihood, to pay such Additional Amounts must remain in effect.

                  In addition, at any time and from time to time prior to June
30, 2000, the Company may redeem up to 35% of the aggregate principal amount of
Securities with the proceeds of one or more Public Equity Offerings (with the
cash proceeds thereof to the extent actually contributed to the Company)
following which there is a Public Market, at a redemption price (expressed as a
percentage of principal amount) of 112% plus accrued interest to the redemption
date (subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date); PROVIDED, HOWEVER,
that at least $45 million aggregate principal amount of the Securities and $100
million aggregate principal amount of the First Priority Notes must remain
outstanding after each such redemption.

                  6.  MANDATORY REDEMPTION

                  In the event an Owner elects to terminate its Building
Contract because of a material breach thereof by the Builders (including a
failure to pay liquidated damages for any delay in the delivery of the related
Vessel), the Securities will be subject to mandatory redemption in part, on a
pro rata basis, in an aggregate principal amount equal to the Allocated
Principal Amount of the Securities for such Vessel and for each other Vessel
that has not been accepted by its related Owner as of the date of such
termination, at a redemption price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest to and including the date of
redemption (subject to the right of a Holder of record on the relevant record
date to receive interest due on the relevant Interest Payment Date), upon the

termination of such Building Contract(s) by the related
Owner(s).

                  If a Vessel is subject to Total Loss, the Securities will be
subject to mandatory redemption in part, on a pro rata basis, in an aggregate
principal amount equal to the Allocated Principal Amount of the Securities for
such Vessel, at a redemption price equal to 101% of the principal amount
thereof, plus accrued and unpaid interest to the date of redemption (subject to
the right of a Holder of record on the relevant record date to receive interest
due on the relevant Interest Payment Date), upon the earlier to occur of (a) the
receipt of the Insurance Proceeds with respect to such Total Loss and (b) 60
days after such Total Loss was deemed to have occurred.

                  7.  NOTICE OF REDEMPTION

more than 60 days before the redemption date to each Holder of Securities to be

                  8.  OFFERS TO PURCHASE

                  Commencing on the first Available Cash Payment Date each

extent of Available Cash on such Available Cash Payment Date, to make an
Available Cash Offer to each Holder of Securities to purchase such Holder's

thereof plus accrued and unpaid interest to the date of purchase (subject to the
right of Holders of record on the relevant record date to receive interests due
on the related Interest Payment Date) as provided in, and subject to the terms
of, the Indenture. Upon a Change of Control, any Holder of Securities will have
the right to cause the Company to purchase all or any part of the Securities of
such Holder at a purchase price equal to 101% of the principal amount of the
Securities to be purchased plus accrued interest to the date of repurchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the related Interest Payment Date) as provided in, and
subject to


<PAGE>

                                                                               9

joint and several senior basis by the Owners.

                  10.  SECURITY

                  The Securities will initially be secured by the Collateral
delivered on the Issue Date. Upon the occurrence of a Delivery Date with respect
to a Vessel the Securities will thereafter be secured by a first priority ship
mortgage on such Vessel and all other Collateral delivered on the Delivery Date
of such Vessel. The Securities will also have the benefit of the Letter of
Credit.

                  11.  DENOMINATIONS; TRANSFER; EXCHANGE

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

                  12.  PERSONS DEEMED OWNERS

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

                  13.  UNCLAIMED MONEY

                  If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back to
the Company at its request unless


<PAGE>

                                                                              10



an abandoned property law designates another Person. After any such payment,
Holders entitled to the money must look only to the Company and not to the
Trustee for payment.


                  14.  DISCHARGE AND DEFEASANCE

                  Subject to certain conditions, the Company at any time may
terminate some or all of its and the Guarantors' obligations under the
Securities, the Security Agreements and the Indenture if the Company deposits
with the Trustee money or U.S. Government Obligations for the payment of
principal and interest on the Securities to redemption or maturity, as the case
may be.

                  15.  AMENDMENT, WAIVER

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount of the Securities and (ii)
any default or noncompliance with any provision may be waived with the written
consent of the Holders of a majority in principal amount of the Securities.
Subject to certain exceptions set forth in the Indenture, without the consent of
any Securityholder, the Company, the Guarantors and the Trustee may amend the
Indenture, the Security Agreements or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 5 of the Indenture,
or to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add additional guarantees with respect to the
Securities or to provide additional security for the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company or
the Guarantors, or to comply with any request of the SEC in connection with
qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Securityholder.

                  16.  DEFAULTS AND REMEDIES

                  Under the Indenture, Events of Default include (i) default for
30 days in payment of interest on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon redemption pursuant to para graph
5 or 6 of the Securities, upon required purchase, upon acceleration or
otherwise, or failure by the Company or the Guarantors to redeem or purchase
Securities when required; (iii) failure by the Company to comply with other
agreements in the Indenture or the Securities, in certain cases subject


<PAGE>

                                                                              11



to notice and lapse of time; (iv) certain accelerations (including failure to
pay within any grace period after final maturity) of other Indebtedness of
Holdings, the Company or the Owners if the amount accelerated (or so unpaid)
exceeds $5.0 million; (v) certain events of bankruptcy or insolvency with
respect to Holdings, the Company or the Owners; (vi) certain judgments or
decrees for the payment of money in excess of $5.0 million, (vii) certain events
or defaults with respect to the Guarantees or the Security Agreements and (ix)
the failure by the Designated Owners to hold certain prescribed percentages of
Voting Stock and Capital Stock of Holdings. If an Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the Securities may declare all the Securities to be due and payable immediately.
Certain events of bankruptcy or insolvency are Events of Default which will
result in the Securities being due and payable immediately upon the occurrence
of such Events of Default.

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

                  17.  TRUSTEE DEALINGS WITH THE COMPANY

                  Subject to certain limitations imposed by the Act, the Trustee
under the Indenture, in its individual or any other capacity, may become the

1.  INTEREST

                  Navigator Gas Transport PLC, an Isle of Man public limited
company (such company, and its successors and assigns under the Indenture
hereinafter referred to, being herein called the "Company"), promises to pay
interest on the principal amount of this Security at the rate per annum shown
above [; PROVIDED, HOWEVER, that if a Registration Default (as defined in the
Registration Rights Agreement) occurs, additional interest will accrue on this
Security at a rate of 0.50% per annum from and including the date on which any
such Registration Default shall occur to but excluding the date on which all
Registration Defaults have been cured] ***/. The Company will pay interest in
cash semiannually on June 30 and December 31 of each year, commencing December
31, 1997, except that at the option of the Company, on any Interest Payment Date
following the delivery of the first Vessel, to the extent cash available for
distribution to Holders of Securities on such date is insufficient to pay all
accrued and unpaid interest on the Securities on such date, the Company may pay
such interest by issuing additional Securities having an aggregate principal
amount equal to the amount of such deficiency, PROVIDED that the Company may not
issue more than $20,900,000 aggregate principal amount of such additional
Securities. Interest on the Securities will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from August 7,
1997. Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

                  The Company will pay interest on the Securities (except
defaulted interest) to the Persons who are registered holders of Securities at
the close of business on the June 15 or December 15 next preceding the interest
payment date even if Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying
Agent to collect principal payments. The Company will pay principal and interest
in money of the United States that at the time of payment is legal tender for
payment of public and private debts. Payments in respect of Securities
(including principal, premium and interest) will be made by wire transfer of
immediately available funds to the accounts specified by the holders thereof or,
if no U.S. dollar account maintained by the payee with a bank in the United
States is designated by any holder to the Trustee or the Paying Agent at least
30 days prior to the relevant due date for payment (or such other date as the
Trustee may accept in its discretion), by mailing a check to the registered
address of such holder.


3.  PAYING AGENT AND REGISTRAR

                  Initially, The Chase Manhattan Bank, a New York banking
corporation ("Trustee"), will act as Paying Agent and Registrar. The Company may
appoint and change any Paying Agent, Registrar or co-registrar without notice.
The Company or any of its domestically incorporated Wholly Owned Subsidiaries
may act as Paying Agent, Registrar or co-registrar.


4.  INDENTURE

                  The Company issued the Securities under an Indenture dated as
of August 1, 1997 ("Indenture"), among the Company, Holdings, the Guarantors and
the Trustee. The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as in effect on the date of the Indenture
(the "Act"). Terms defined in the Indenture and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
such terms, and Securityholders are referred to the Indenture and the Act for a
statement of those terms.

2.06 of the Indenture and subject to the issuance of up to $20,900,000 aggregate
principal amount of Securities under the circumstances described in paragraph 1

regulations or published tax rulings of the Isle of Man or any Successor
Jurisdiction, or of any political subdivision or taxing authority thereof or
therein, or any change in the official administration, application or
interpretation of such laws, regulations or published tax rulings either

after such issue date, it is determined by the Company or the relevant Owners,
as the case may be, that the Company or the relevant Owners, as the case may be,
would be required to pay, any Additional Amounts pursuant to the Indenture or
the terms of any Security in respect of interest on the next succeeding Interest
Payment Date (assuming, in the case of the Owners, that a payment in respect of
such interest were required to be made by the relevant Owners under the
Guarantees on such Interest Payment Date), and that such obligation cannot be
avoided by the Company or the relevant Owners taking reasonable measures
available to it, the Company or the relevant Owners, as the case may be, may, at
its option, redeem all (but not less than all) the Securities in respect of
which such Additional Amounts would be so payable at any time, at a redemption
price equal to 100% of the principal amount thereof plus accrued interest to the
date fixed for redemption; PROVIDED, HOWEVER, that (a) no such notice of
redemption may be given earlier than 60 days prior to the earliest date on which
the Company or the relevant Owners, as the case may be, would be obligated, or
is substantially likely to be obligated, to pay such Additional Amounts were a
payment in respect of the Securities or the Guarantees, as the case may be, then
due, and (b) at the time any such redemption notice is given, such obligation,
or substantial likelihood, to pay such Additional Amounts must remain in effect.

          In addition, at any time and from time to time prior to June 30, 2000,
the Company may redeem up to 35% of the aggregate principal amount of Securities
with the proceeds of one or more Public Equity Offerings (with the cash proceeds
thereof to the extent actually contributed to the Company) following which there
is a Public Market, at a redemption price (expressed as a percentage of
principal amount) of 112% plus accrued interest to the redemption date (subject
to the right of Holders of record on the relevant record date to receive
interest due on the related interest payment date); PROVIDED, HOWEVER, that at
least $45 million aggregate principal amount of the Securities and $100 million
aggregate principal amount of the First Priority Notes must remain outstanding
after each such redemption.


6.  MANDATORY REDEMPTION

                  In the event an Owner elects to terminate its Building

with the Company or its Affiliates with the same rights it would have if it were
not Trustee.

         On the Issue Date, Navigator Gas Transport PLC (the "Issuer") issued
Notes in connection with the financing of the construction of the Vessels. The
net proceeds of such issuance were deposited into the Pre-Funding Account.
Pursuant to the Intercreditor Agreement, the Allocated Principal Amount of the

under the Building Contract for the Vessel. The Notes are guaranteed jointly and
severally by the Owner and the other Owners pursuant to the Guarantees. As

Suisse First Boston, acting through its London branch as funding bank and
administrating bank for the participating banks party to the Letter of Credit
Reimbursement Agreement (as defined below) (the "Letter of Credit Issuer") is
issuing a letter of credit (the "Letter of Credit"). As further collateral for
the Notes and the obligations under the Letter of Credit Reimbursement
Agreement, the Trustees, the Letter of Credit Issuer, Holdings, the Issuer and
the Owners have entered into a Collateral Agency and Intercreditor Agreement
(the "Intercreditor Agreement"), dated as of August 1, 1997. The Issuer's

Letter of Credit, the Owners guaranty thereof and Holdings' pledge in respect
thereto is set forth in the Letter of Credit Reimbursement Agreement and
Guaranty (the "Letter of Credit Reimbursement Agreement"), dated as of August 7,
1997, among the Letter of Credit Issuer, the participating banks from time to
time party thereto, the Issuer, Holdings and the Owners. The Vessel will be
managed by Navigator Gas Management Limited (the "Manager") pursuant to the
Management Agreement, dated as of the date hereof, among Holdings, the Owners
and the Manager. As collateral security for its obligations under the
Indentures, the Letter of Credit Reimbursement Agreement and the other Security
Agreements, the Owner has and will assign, pledge, mortgage and grant the
Collateral Agent a security interest in, INTER ALIA, the Vessel, the earnings
and insurances of the Vessel and will grant this debenture in favor of the
Collateral Agent.

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

Security Asset is registered or who is the holder thereof under the terms
thereof or otherwise including, but without limitation, all the powers given to
trustees by statute in respect of securities or property subject to a trust;

Owner for any sum or other distribution paid in respect of such Security Asset.

give all notices, orders and directions which the Collateral Agent may think
expedient and, for the purposes of this Section, a certificate in writing by the

required by it is reasonably required shall be conclusive evidence of such fact

things which the Owner ought to do but fails to do under the covenants and
provisions contained in the Indentures, the Letter of Credit Reimbursement

Agreement (including without prejudice to the generality of the foregoing to
make any demand upon or give any notice or receipt to any Person owing moneys to

within the period of six months in the case of fixed security and twelve months
in the case of floating security after such termination a petition shall be
presented to a competent court for an order for the winding up of the Owner or
the Owner shall commence to be wound up voluntarily, the Collateral Agent shall
be at liberty, notwithstanding as aforementioned, to continue to retain such
security or any part thereof for and during such further period as the
Collateral Agent in its absolute discretion shall determine. The Owner agrees
that such security shall be deemed to have been and to have remained held by the
Collateral Agent as and by way of security for the payment to the Collateral
Agent of all or any sums which are now or may become due and owing to the
Collateral Agent under the Indentures, the Letter of Credit Reimbursement
Agreement, the Intercreditor Agreement and the rest of the Security Agreements.

payments or receipts received by it or them or the Owner or to present or file

of any other right. The rights provided in this Debenture are cumulative and not
exclusive of any rights provided by law, agreement or otherwise. Any waiver and
any consent by the Collateral Agent under this Debenture must be in writing and
may be given subject to any conditions thought fit by the Collateral Agent. Any

                  conducive to any of the matters or rights conferred on a
                  Receiver under or by virtue of this Debenture and to exercise
                  in relation to any Security Asset all such rights as the
                  Receiver should be capable of exercising if the Receiver were
                  the beneficial owner of the same; and

         (p)      MONEYS RECEIVED BV RECEIVER. All moneys received by a Receiver
                  shall after providing for the matters specified by any law be
                  applied by him in or towards satisfaction of this Debenture
                  and thereafter of any other Encumbrance of which he shall have
                  notice and thereafter the Receiver shall pay the residue of
                  the moneys received by him to the Owner.

         Section 7.2. COMPLY WITH INSTRUCTIONS. Any Receiver shall in the
exercise of the Receiver's rights conform to any regulations and directions from
time to time made and given by the Collateral Agent as appointed but so that no
Person dealing with the Collateral Agent or any Receiver shall be concerned to
enquire whether the Receiver has so conformed to any such regulations or
directions.

         Section 7.3. REMOVAL AND REMUNERATION. The Collateral Agent may from
time to time by writing under its hand remove any Receiver appointed by it and
may whenever it may deem it expedient appoint a new Receiver in the place of any
Receiver whose appointment may for any reason have terminated and may from time
to time fix the remuneration of any Receiver appointed by it.

         Section 7.4. COLLATERAL AGENT MAY EXERCISE RECEIVER'S POWERS. All or
any of the rights which are conferred by this Debenture (either expressly or
impliedly) upon a Receiver of any Security Asset may be exercised after the
security hereby created becomes enforceable by the Collateral Agent in relation
to any Security Asset without first appointing a Receiver of the same or
notwithstanding the appointment of a Receiver of the same.

         Section 7.5. NO LIABILITY FOR ENTERING INTO POSSESSION. The Collateral
Agent shall not nor shall any Receiver appointed as aforesaid by reason of the
Collateral Agent or the Receiver entering into possession of any Security Asset
be liable to account for such entry into possession or be liable for any loss or
realization or for any fault or omission for which such acts may have made them
liable. Every Receiver duly appointed by the Collateral Agent shall be deemed to
be the agent of the Owner for all purposes and shall as such agent be deemed to
be in the same position as a Receiver duly appointed under this Debenture. The
Owner alone shall be responsible for its agreements, obligations, acts,
omissions, defaults and losses and the Collateral Agent shall not incur any
responsibility therefor (either to the Owner or to any other Person whatsoever)
by reason of appointing such Receiver or for any other reason whatsoever. Every
such Receiver and the Collateral Agent shall be entitled to all the rights,
privileges and immunities by statute conferred on receivers when such receivers
have been duly appointed.

         Section 7.6. PROTECTION OF THIRD PARTIES. No purchaser, mortgagee or
other Person dealing with the Collateral Agent or the Receiver or the agents of
the Collateral Agent or the Receiver shall be concerned to enquire whether any
of the Obligations are due or owing, the right which the Collateral Agent or the
Receiver is purporting to exercise has become exercisable or any money remains
due under this Debenture, as to the propriety or regularity of the actions of
the Collateral Agent or such Receiver, or to see to the application of any money
paid to the Collateral Agent or to such Receiver.

         Section 7.7. EXPENSES. All costs, charges and expenses incurred and all
payments made by the Collateral Agent or any Receiver appointed hereunder in the
exercise in good faith of any right hereby conferred whether or not occasioned
by any act, neglect or default of the Collateral Agent or such Receiver shall
bear interest from the date of the same being incurred or becoming due at the
rate at which interest accrues on the Second Priority Notes. The amount of all
such costs, charges, expenses and payments and all interest thereon and all
remuneration payable hereunder shall be payable by the Owner on demand. All such
costs, charges, expenses and payments shall be paid and charged as between the
Collateral Agent and the Owner on the basis of a full indemnity and not on the
basis of party and party or any other kind of taxation.

         Section 7.8. INDEMNITY. Each of the Collateral Agent, the Letter of
Credit Issuer, the Participating Banks, the First Priority Trustee, the Second
Priority Trustee and every Receiver, attorney, manager, agent or other Person
appointed by the Collateral Agent hereunder shall be entitled to be indemnified
out of the Security Assets in respect of all obligations, costs, charges and
expenses incurred and payments made by such Person in good faith in the
execution or purported execution of any right vested in such Person pursuant
hereto and against all actions, proceedings, obligations, costs, claims and
demands in respect of any matter or thing done or omitted in anyway relating to
any Security Asset and the Collateral Agent, the Letter of Credit Issuer, the
Participating Banks, the First Priority Trustee, the Second Priority Trustee and
any such Receiver may retain and pay all sums in respect of the same out of any
moneys received under the rights hereby conferred.

         Section 8.1. ORDER OF APPLICATION. Any moneys received by the
Collateral Agent pursuant to this Debenture or under the powers hereby conferred
shall after the security hereby constituted shall have become enforceable but
subject to the payment of any claims having priority to this security be applied
for the purposes and in the order of priority indicated in the Intercreditor
Agreement.

         Section 8.2. SUSPENSE ACCOUNTS. Any moneys received under the rights
hereby conferred may, at the discretion of the Collateral Agent, be placed in a
suspense account and kept there for so long as the Collateral Agent thinks fit.

irrevocably and unconditionally waives any objection which it may now or

may acquire any immunity from jurisdiction of any court or from any legal
process (whether through service of notice, attachment prior to judgment,
attachment in aid of execution, execution or otherwise) with respect to itself
or its property, it hereby irrevocably waives such immunity in this Agreement to
the extent permitted by law. The Owner hereby irrevocably appoints and

Debenture shall have been paid in full. If such agent shall cease to so act, the
Owner shall immediately designate and appoint another such agent satisfactory to
the Collateral Agent and shall promptly deliver to the Collateral Agent evidence

further agrees to take any and all actions, including the execution and filing
of any and all such documents and instruments, as may be necessary to continue

                  creditor of the Owner or relating in any way to any Security
                  Asset;

         (d)      Borrow and Create Security. Borrow or raise money and secure

                  this Debenture (whether or not in priority to the sums and
                  obligations secured by this Debenture) in such manner and on
                  such terms as the Receiver shall think fit; PROVIDED, HOWEVER,
                  that:

                  (i)      no Receiver shall exercise such right without first
                           obtaining the written consent of the Person
                           appointing him and the Collateral Agent shall not
                           incur any responsibility to the Owner or any other
                           Person by reason of giving or refusing its consent,

be the agent of the Owner for all purposes and shall as such agent be deemed to
be in the same position as a Receiver duly appointed under this Debenture. The
Owner alone shall be responsible for its agreements, obligations, acts,

payments made by the Collateral Agent or any Receiver appointed hereunder in the
exercise in good faith of any right hereby conferred whether or not occasioned
by any act, neglect or default of the Collateral Agent or such Receiver shall
bear interest from the date of the same being incurred or becoming due at the
rate at which interest accrues on the Second Priority Notes. The amount of all
such costs, charges, expenses and payments and all interest thereon and all
remuneration payable hereunder shall be payable by the Owner on demand. All such
costs, charges, expenses and payments shall be paid and charged as between the
Collateral Agent and the Owner on the basis of a full indemnity and not on the
basis of party and party or any other kind of taxation.

         Section 7.8. INDEMNITY. Each of the Collateral Agent, the Letter of
Credit Issuer, the Participating Banks, the First Priority Trustee, the Second
Priority Trustee and every Receiver, attorney, manager, agent or other Person

demands in respect of any matter or thing done or omitted in anyway relating to

moneys received under the rights hereby conferred.

the Notes and the obligations under the Letter of Credit Reimbursement
Agreement, the Trustees, the Letter of Credit Issuer, Holdings, the Issuer and

Letter of Credit, the Owners guaranty thereof and Holdings' pledge in respect

time party thereto, the Issuer, Holdings and the Owners. The Vessel will be
managed by Navigator Gas Management Limited (the "Manager") pursuant to the
Management Agreement, dated as of the date hereof, among Holdings, the Owners
and the Manager. As collateral security for its obligations under the
Indentures, the Letter of Credit Reimbursement Agreement and the other Security
Agreements, the Owner has and will assign, pledge, mortgage and grant the
Collateral Agent a security interest in, INTER ALIA, the Vessel, the earnings
and insurances of the Vessel and will grant this debenture in favor of the
Collateral Agent.

herein contained and of other valuable consideration, receipt of which is hereby
acknowledged, the Owner and the Collateral Agent hereby agree as follows:

deemed to be affected by notice whether actual or constructive of any subsequent
Encumbrance or other interest affecting any Security Asset or the proceeds of
sale thereof, the Collateral Agent may open a new account or accounts for the

and shall not operate to reduce the amount for which this Debenture is security.

                  as are conferred by the Memorandum of Association and Articles

                  or necessary for realizing any Security Asset or incidental or
                  conducive to any of the matters or rights conferred on a
                  Receiver under or by virtue of this Debenture and to exercise
                  in relation to any Security Asset all such rights as the
                  Receiver should be capable of exercising if the Receiver were
                  the beneficial owner of the same; and

         (p)      MONEYS RECEIVED BV RECEIVER. All moneys received by a Receiver
                  shall after providing for the matters specified by any law be

         Section 7.5. NO LIABILITY FOR ENTERING INTO POSSESSION. The Collateral
Agent shall not nor shall any Receiver appointed as aforesaid by reason of the
Collateral Agent or the Receiver entering into possession of any Security Asset
be liable to account for such entry into possession or be liable for any loss or
realization or for any fault or omission for which such acts may have made them
liable. Every Receiver duly appointed by the Collateral Agent shall be deemed to
be the agent of the Owner for all purposes and shall as such agent be deemed to
be in the same position as a Receiver duly appointed under this Debenture. The
Owner alone shall be responsible for its agreements, obligations, acts,
omissions, defaults and losses and the Collateral Agent shall not incur any
responsibility therefor (either to the Owner or to any other Person whatsoever)
by reason of appointing such Receiver or for any other reason whatsoever. Every
such Receiver and the Collateral Agent shall be entitled to all the rights,
privileges and immunities by statute conferred on receivers when such receivers
have been duly appointed.

         Section 7.6. PROTECTION OF THIRD PARTIES. No purchaser, mortgagee or
other Person dealing with the Collateral Agent or the Receiver or the agents of

of the Obligations are due or owing, the right which the Collateral Agent or the
Receiver is purporting to exercise has become exercisable or any money remains
due under this Debenture, as to the propriety or regularity of the actions of
the Collateral Agent or such Receiver, or to see to the application of any money
paid to the Collateral Agent or to such Receiver.

         Section 7.7. EXPENSES. All costs, charges and expenses incurred and all
payments made by the Collateral Agent or any Receiver appointed hereunder in the
exercise in good faith of any right hereby conferred whether or not occasioned
by any act, neglect or default of the Collateral Agent or such Receiver shall
bear interest from the date of the same being incurred or becoming due at the
rate at which interest accrues on the Second Priority Notes. The amount of all
such costs, charges, expenses and payments and all interest thereon and all
remuneration payable hereunder shall be payable by the Owner on demand. All such
costs, charges, expenses and payments shall be paid and charged as between the
Collateral Agent and the Owner on the basis of a full indemnity and not on the
basis of party and party or any other kind of taxation.

         Section 7.8. INDEMNITY. Each of the Collateral Agent, the Letter of
Credit Issuer, the Participating Banks, the First Priority Trustee, the Second
Priority Trustee and every Receiver, attorney, manager, agent or other Person
appointed by the Collateral Agent hereunder shall be entitled to be indemnified
out of the Security Assets in respect of all obligations, costs, charges and
expenses incurred and payments made by such Person in good faith in the
execution or purported execution of any right vested in such Person pursuant
hereto and against all actions, proceedings, obligations, costs, claims and
demands in respect of any matter or thing done or omitted in anyway relating to
any Security Asset and the Collateral Agent, the Letter of Credit Issuer, the
Participating Banks, the First Priority Trustee, the Second Priority Trustee and
any such Receiver may retain and pay all sums in respect of the same out of any
moneys received under the rights hereby conferred.

         Section 6.1. WHEN SECURITY BECOMES ENFORCEABLE. The security hereby
conferred shall become immediately enforceable and the floating charge created
by this Debenture shall be deemed to have crystallized and an unrestricted power
of sale together with any powers conferred by statute as varied or amended or
granted by this Debenture shall be immediately exercisable by the Collateral
Agent (i) if the Owner fails to meet the Obligations in the manner specified in
Section 2.1 or (ii) upon and after the occurrence of any Event of Default. After

enforce all or any part of this security, and exercise all or any rights of
enforcement hereby granted, in such manner as the Collateral Agent sees fit.

payable on the date hereof and any statutory restrictions on the power of sale
and restrictions on the right of consolidation shall not apply to this security.

         Section 6.3. REMEDIES, WAIVERS AND CONSENTS. No delay or omission of
the Collateral Agent in exercising any right under this Debenture shall impair
or be construed as a waiver of such right nor shall any single or partial
exercise of any such right preclude any further exercise thereof or the exercise
of any other right. The rights provided in this Debenture are cumulative and not
exclusive of any rights provided by law, agreement or otherwise. Any waiver and
any consent by the Collateral Agent under this Debenture must be in writing and
may be given subject to any conditions thought fit by the Collateral Agent. Any
waiver or consent shall be effective only in the instance and for the purpose
for which it is given.

         Section 6.4. EXERCISE OF POWERS. All or any of the powers conferred on
a receiver by Article VII hereof may be exercised by the Collateral Agent
without first appointing a Receiver or notwithstanding the appointment of a

                  creditor of the Owner or relating in any way to any Security
                  Asset;

         (d)      Borrow and Create Security. Borrow or raise money and secure

                  this Debenture (whether or not in priority to the sums and
                  obligations secured by this Debenture) in such manner and on
                  such terms as the Receiver shall think fit; PROVIDED, HOWEVER,
                  that:

                  (i)      no Receiver shall exercise such right without first
                           obtaining the written consent of the Person
                           appointing him and the Collateral Agent shall not
                           incur any responsibility to the Owner or any other
                           Person by reason of giving or refusing its consent,

Collateral Agent or the Receiver entering into possession of any Security Asset

liable. Every Receiver duly appointed by the Collateral Agent shall be deemed to
be the agent of the Owner for all purposes and shall as such agent be deemed to
be in the same position as a Receiver duly appointed under this Debenture. The
Owner alone shall be responsible for its agreements, obligations, acts,
omissions, defaults and losses and the Collateral Agent shall not incur any
responsibility therefor (either to the Owner or to any other Person whatsoever)

payments made by the Collateral Agent or any Receiver appointed hereunder in the
exercise in good faith of any right hereby conferred whether or not occasioned
by any act, neglect or default of the Collateral Agent or such Receiver shall
bear interest from the date of the same being incurred or becoming due at the
rate at which interest accrues on the Second Priority Notes. The amount of all
such costs, charges, expenses and payments and all interest thereon and all
remuneration payable hereunder shall be payable by the Owner on demand. All such
costs, charges, expenses and payments shall be paid and charged as between the
Collateral Agent and the Owner on the basis of a full indemnity and not on the
basis of party and party or any other kind of taxation.

         Section 7.8. INDEMNITY. Each of the Collateral Agent, the Letter of
Credit Issuer, the Participating Banks, the First Priority Trustee, the Second
Priority Trustee and every Receiver, attorney, manager, agent or other Person

out of the Security Assets in respect of all obligations, costs, charges and
expenses incurred and payments made by such Person in good faith in the
execution or purported execution of any right vested in such Person pursuant
hereto and against all actions, proceedings, obligations, costs, claims and
demands in respect of any matter or thing done or omitted in anyway relating to
any Security Asset and the Collateral Agent, the Letter of Credit Issuer, the
Participating Banks, the First Priority Trustee, the Second Priority Trustee and
any such Receiver may retain and pay all sums in respect of the same out of any
moneys received under the rights hereby conferred.

and insurances of the Vessel and will grant this debenture in favor of the

Agreements, the Owner shall not, without the prior written consent of the

disposition of any Security Asset, or any Encumbrance or other right in or over
any Security Asset to subsist, arise or be created, other than such Encumbrance
as is created by this Debenture.

         Section 3.5. NEW ACCOUNTS. If the Collateral Agent receives or is
deemed to be affected by notice whether actual or constructive of any subsequent
Encumbrance or other interest affecting any Security Asset or the proceeds of
sale thereof, the Collateral Agent may open a new account or accounts for the

<PAGE>

                                       -4-

be treated as if it had done so at the time when it received or was deemed to
have received notice and as from that time all payments made to the Collateral
Agent shall be credited or be treated as having been credited to the new account
and shall not operate to reduce the amount for which this Debenture is security.

the Owner shall commence to be wound up voluntarily, the Collateral Agent shall
be at liberty, notwithstanding as aforementioned, to continue to retain such
security or any part thereof for and during such further period as the
Collateral Agent in its absolute discretion shall determine. The Owner agrees

Collateral Agent as and by way of security for the payment to the Collateral
Agent of all or any sums which are now or may become due and owing to the

any consent by the Collateral Agent under this Debenture must be in writing and

                  conducive to any of the matters or rights conferred on a
                  Receiver under or by virtue of this Debenture and to exercise
                  in relation to any Security Asset all such rights as the
                  Receiver should be capable of exercising if the Receiver were
                  the beneficial owner of the same; and

         (p)      MONEYS RECEIVED BV RECEIVER. All moneys received by a Receiver
                  shall after providing for the matters specified by any law be
                  applied by him in or towards satisfaction of this Debenture
                  and thereafter of any other Encumbrance of which he shall have
                  notice and thereafter the Receiver shall pay the residue of
                  the moneys received by him to the Owner.

         Section 7.2. COMPLY WITH INSTRUCTIONS. Any Receiver shall in the
exercise of the Receiver's rights conform to any regulations and directions from
time to time made and given by the Collateral Agent as appointed but so that no
Person dealing with the Collateral Agent or any Receiver shall be concerned to
enquire whether the Receiver has so conformed to any such regulations or
directions.

         Section 7.3. REMOVAL AND REMUNERATION. The Collateral Agent may from
time to time by writing under its hand remove any Receiver appointed by it and
may whenever it may deem it expedient appoint a new Receiver in the place of any
Receiver whose appointment may for any reason have terminated and may from time
to time fix the remuneration of any Receiver appointed by it.

         Section 7.4. COLLATERAL AGENT MAY EXERCISE RECEIVER'S POWERS. All or
any of the rights which are conferred by this Debenture (either expressly or
impliedly) upon a Receiver of any Security Asset may be exercised after the
security hereby created becomes enforceable by the Collateral Agent in relation
to any Security Asset without first appointing a Receiver of the same or
notwithstanding the appointment of a Receiver of the same.

         Section 7.5. NO LIABILITY FOR ENTERING INTO POSSESSION. The Collateral
Agent shall not nor shall any Receiver appointed as aforesaid by reason of the
Collateral Agent or the Receiver entering into possession of any Security Asset
be liable to account for such entry into possession or be liable for any loss or
realization or for any fault or omission for which such acts may have made them
liable. Every Receiver duly appointed by the Collateral Agent shall be deemed to
be the agent of the Owner for all purposes and shall as such agent be deemed to
be in the same position as a Receiver duly appointed under this Debenture. The
Owner alone shall be responsible for its agreements, obligations, acts,
omissions, defaults and losses and the Collateral Agent shall not incur any
responsibility therefor (either to the Owner or to any other Person whatsoever)
by reason of appointing such Receiver or for any other reason whatsoever. Every
such Receiver and the Collateral Agent shall be entitled to all the rights,
privileges and immunities by statute conferred on receivers when such receivers
have been duly appointed.

         Section 7.6. PROTECTION OF THIRD PARTIES. No purchaser, mortgagee or
other Person dealing with the Collateral Agent or the Receiver or the agents of
the Collateral Agent or the Receiver shall be concerned to enquire whether any
of the Obligations are due or owing, the right which the Collateral Agent or the
Receiver is purporting to exercise has become exercisable or any money remains
due under this Debenture, as to the propriety or regularity of the actions of
the Collateral Agent or such Receiver, or to see to the application of any money
paid to the Collateral Agent or to such Receiver.

         Section 7.7. EXPENSES. All costs, charges and expenses incurred and all
payments made by the Collateral Agent or any Receiver appointed hereunder in the
exercise in good faith of any right hereby conferred whether or not occasioned
by any act, neglect or default of the Collateral Agent or such Receiver shall
bear interest from the date of the same being incurred or becoming due at the
rate at which interest accrues on the Second Priority Notes. The amount of all
such costs, charges, expenses and payments and all interest thereon and all
remuneration payable hereunder shall be payable by the Owner on demand. All such
costs, charges, expenses and payments shall be paid and charged as between the
Collateral Agent and the Owner on the basis of a full indemnity and not on the
basis of party and party or any other kind of taxation.

         Section 7.8. INDEMNITY. Each of the Collateral Agent, the Letter of
Credit Issuer, the Participating Banks, the First Priority Trustee, the Second
Priority Trustee and every Receiver, attorney, manager, agent or other Person
appointed by the Collateral Agent hereunder shall be entitled to be indemnified
out of the Security Assets in respect of all obligations, costs, charges and
expenses incurred and payments made by such Person in good faith in the
execution or purported execution of any right vested in such Person pursuant
hereto and against all actions, proceedings, obligations, costs, claims and
demands in respect of any matter or thing done or omitted in anyway relating to
any Security Asset and the Collateral Agent, the Letter of Credit Issuer, the
Participating Banks, the First Priority Trustee, the Second Priority Trustee and
any such Receiver may retain and pay all sums in respect of the same out of any
moneys received under the rights hereby conferred.

         Section 8.1. ORDER OF APPLICATION. Any moneys received by the
Collateral Agent pursuant to this Debenture or under the powers hereby conferred

subject to the payment of any claims having priority to this security be applied
for the purposes and in the order of priority indicated in the Intercreditor
Agreement.

         Section 8.2. SUSPENSE ACCOUNTS. Any moneys received under the rights
hereby conferred may, at the discretion of the Collateral Agent, be placed in a

Debenture shall have been paid in full. If such agent shall cease to so act, the
Owner shall immediately designate and appoint another such agent satisfactory to
the Collateral Agent and shall promptly deliver to the Collateral Agent evidence

UNITED   STATES TRUST COMPANY OF NEW YORK,

                  1.       INTEREST

                  NAVIGATOR GAS TRANSPORT PLC, an Isle of Man public limited
company (such corporation, and its successors and assigns under the Indenture
hereinafter referred to, being herein called the "Company"), promises to pay
interest on the principal amount of this Security at the rate per annum shown
above; PROVIDED, HOWEVER, that if a Registration Default (as defined in the
Registration Rights Agreement) occurs, additional interest will accrue on this
Security at a rate of 0.50% per annum from and including the date on which any
such Registration Default shall occur to but excluding the date on which all
Registration Defaults have been cured. The Company will pay interest
semiannually on June 30 and December 31 of each year, commencing December 31,
1997. Interest on the Securities will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from August 7, 1997.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus _% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.


                  2.       METHOD OF PAYMENT

                  The Company will pay interest on the Securities (except
defaulted interest) to the Persons who are registered holders of Securities at
the close of business on the June 15 or December 15 next preceding the interest
payment date even if Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying
Agent to collect principal payments. The Company will pay principal and interest
in money of the United States that at the time of payment is legal tender for
payment of public and private debts. Payments in respect of the Securities
represented by a Global Security (including principal, premium and interest)
will be made by wire transfer of immediately available funds to the accounts
specified by The Depository Trust Company. The Company will make all payments in
respect of a certificated Security (including principal, premium and interest)
by mailing a check to the registered address of each Holder thereof; provided,
however, that payments on a certificated Security will be made by wire transfer
to a U.S. dollar account maintained by the payee with a bank in the United
States if such Holder elects payment by wire transfer by giving written notice
to the Trustee or the Paying Agent to such effect designating such account no
later than 30 days immediately pre ceding the relevant due date for payment (or
such other date as the Trustee may accept in its discretion).


                  3.       PAYING AGENT AND REGISTRAR

                  Initially, United States Trust Company of New York, a bank and
trust company organized under the New York Banking Law ("Trustee"), will act as
Paying Agent and Registrar. The Company may appoint and change any Paying Agent,
Registrar or co-registrar without notice. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or
co-registrar.

                  4.       INDENTURE

                  The Company issued the Securities under an Indenture dated as
of August 1, 1997 ("Indenture"), among the Company, Holdings, the Guarantors and
the Trustee. The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as in effect on the date of the Indenture
(the "Act"). Terms defined in the Indenture and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
such terms, and Securityholders are referred to the Indenture and the Act for a
statement of those terms.

                  The Securities are general secured obligations of the Company
limited to $217,000,000 aggregate principal amount (subject to Section 2.06 of
the Indenture). The Indenture limits (i) the incurrence of additional debt by
the Company and the Owner, (ii) the payment of dividends on capital stock of the
Company and the purchase, redemption or retirement of capital stock or
subordinated indebtedness, (iii) investments, (iv) certain liens and
sale/leaseback transactions, (v) certain transactions with affiliates, (vi)
sales of assets, (vii) the issuance or sale of capital stock of subsidiaries and
(viii) certain consolidations, mergers and transfers of assets. The Indenture
also prohibits certain restrictions on distributions from the Owners.

                  5.       OPTIONAL REDEMPTION

                  Except as set forth in the next two paragraphs, the Securities
may not be redeemed prior to June 30, 2002. On and after that date, the Company
may redeem the Securities in whole at any time or in part from time to time at
the following redemption prices (expressed in percentages of principal amount),
plus accrued interest to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on the related
Interest Payment Date):

                  if redeemed during the 12-month period beginning June 30,

                  PERIOD                                        PERCENTAGE

                  2005 and thereafter  . . . . . . . . .        100.000

                  If, as a result of any change in or any amendment to the laws,
regulations or published tax rulings of the Isle of Man or any Successor
Jurisdiction, or of any political subdivision or taxing authority thereof or
therein, or any change in the official administration, application or
interpretation of such laws, regulations or published tax rulings either
generally or in relation to any particular Securities, which change in official
administration, application or interpretation shall not have been available to
the public prior to such issue date and is notified to the Company or the
relevant Owners, as the case may be, on or after such issue date, it is
determined by the Company or the relevant Owners, as the case may be, that the
Company or the relevant Owners, as the case may be, would be required to pay,
any Additional Amounts pursuant to the Indenture or the terms of any Security in
respect of interest on the next succeeding Interest Payment Date (assuming, in
the case of the Owners, that a payment in respect of such interest were required
to be made



                                        4

<PAGE>




by the relevant Owners under the Guarantees on such Interest Payment Date), and
that such obligation cannot be avoided by the Company or the relevant Owners
taking reasonable measures available to it, the Company or the relevant Owners,
as the case may be, may, at its option, redeem all (but not less than all) the
Securities in respect of which such Additional Amounts would be so payable at
any time, at a redemption price equal to 100% of the principal amount thereof
plus accrued interest to the date fixed for redemption; provided, however, that
(a) no such notice of redemption may be given earlier than 60 days prior to the
earliest date on which the Company or the relevant Owners, as the case may be,
would be obligated, or is substantially likely to be obligated, to pay such
Additional Amounts were a payment in respect of the Securities or the
Guarantees, as the case may be, then due, and (b) at the time any such
redemption notice is given, such obligation, or substantial likelihood, to pay
such Additional Amounts must remain in effect.

                  In addition, at any time and from time to time prior to June
30, 2000, the Company may redeem up to 35% of the aggregate principal amount of
Securities with the proceeds of one or more Public Equity Offerings (with the
cash proceeds thereof to the extent actually contributed to the Company)
following which there is a Public Market, at a redemption price (expressed as a
percentage of principal amount) of 110.5% plus accrued interest to the
redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the related interest payment date);
provided, however, that at least $100 million aggregate principal amount of the
Securities and $45 million aggregate principal amount of the Second Priority
Notes must remain outstanding after each such redemption.


                  6.       MANDATORY REDEMPTION

                  In the event an Owner elects to terminate its Building
Contract because of a material breach thereof by the Builders (including a
failure to pay liquidated damages for any delay in the delivery of the related
Vessel), the Securities will be subject to mandatory redemption in part, on a
pro rata basis, in an aggregate principal amount equal to the Allocated
Principal Amount of the Securities for such Vessel and for each other Vessel
that has not been accepted by its related Owner as of the date of such
termination, at a redemption price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest to and including the date of
redemption (subject to the right of a Holder of record on the relevant record
date to receive interest due on the relevant Interest Payment Date), upon the
earlier to occur of (a) the receipt of the Refund Amount with respect to the
related Building Contract(s) and (b) 60 days after the termination of such
Building Contract(s) by the related Owner(s).

                  If a Vessel is subject to Total Loss, the Securities will be
subject to mandatory redemption in part, on a pro rata basis, in an aggregate
principal amount equal to the Allocated Principal Amount of the Securities for
such Vessel, at a redemption price equal to 101% of the principal amount
thereof, plus accrued and unpaid interest to the date of redemption (subject to
the right of a Holder of record on the relevant record date to receive interest
due on the relevant Interest Payment Date), upon the earlier to occur of (a) the
receipt of the Insurance Proceeds with respect to such Total Loss and (b) 60
days after such Total Loss was deemed to have occurred.

                  7.       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 of Securities to be
redeemed at his registered address. Securities in denominations larger than
$1,000 may be redeemed in part but only in whole multiples of $1,000. If money
sufficient to pay the redemption price of and accrued interest on all Securities
(or portions thereof) to be redeemed on the redemption date is deposited with
the Paying Agent on or before the redemption date, on and after such date
interest ceases to accrue on such Securities (or such portions thereof) called
for redemption.


                  8.       OFFERS TO PURCHASE

                  On each Available Cash Payment Date, the Company will be
required, to the extent of Available Cash on such Available Cash Payment Date,
to make an Available Cash Offer to each Holder of Securities to purchase such
Holder's Securities in whole or in part, at a price equal to 102% of the
principal amount thereof plus accrued and unpaid interest to the date of
purchase (subject to the right of Holders of record on the relevant record date
to receive interests due on the related Interest Payment Date) as provided in,
and subject to the terms of, the Indenture. Upon a Change of Control, any Holder
of Securities will have the right to cause the Company to purchase all or any
part of the Securities of such Holder at a purchase price equal to 101% of the
principal amount of the Securities to be purchased plus accrued interest to the
date of repurchase (subject to the right of Holders of record on the relevant
record date to receive interest due on the related Interest Payment Date) as
provided in, and subject to the terms of, the Indenture.


                  9.       GUARANTEE

                  The payment by the Company of the principal of, and premium
and interest on, the Securities is fully and unconditionally guaranteed on a
joint and several senior basis by the Owners.


                  10.      SECURITY

                  The Securities will initially be secured by the Collateral
delivered on the Issue Date. Upon the occurrence of a Delivery Date with respect
to a Vessel the Securities will thereafter be secured by a first priority ship
mortgage on such Vessel and all other Collateral delivered on the Delivery Date
of such Vessel. The Securities will also have the benefit of the Letter of
Credit.


                  11.      DENOMINATIONS; TRANSFER; EXCHANGE

                  The Securities are in registered form without coupons in
denominations of $1,000 and whole multiples of $1,000. A Holder may transfer or
exchange Securities in accordance with the Indenture. The Registrar may require
a Holder, among other things, to furnish appropriate endorsements or transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture. The Registrar need not register the transfer



                                        6

<PAGE>




of or exchange any Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
or any Securities for a period of 15 days before a selection of Securities to be
redeemed or 15 days before an interest payment date.


                  12.      PERSONS DEEMED OWNERS

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


                  13.      UNCLAIMED MONEY

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


                  14.      DISCHARGE AND DEFEASANCE

                  Subject to certain conditions, the Company at any time may
terminate some or all of its and the Guarantors' obligations under the
Securities, the Security Agreements and the Indenture if the Company deposits
with the Trustee money or U.S. Government Obligations for the payment of
principal and interest on the Securities to redemption or maturity, as the case
may be.


                  15.      AMENDMENT, WAIVER

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount of the Securities and (ii)
any default or noncompliance with any provision may be waived with the written
consent of the Holders of a majority in principal amount of the Securities.
Subject to certain exceptions set forth in the Indenture, without the consent of
any Securityholder, the Company, the Guarantors and the Trustee may amend the
Indenture, the Security Agreements or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 5 of the Indenture,
or to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add additional guarantees with respect to the
Securities or to provide additional security for the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company or
the Guarantors, or to comply with any request of the SEC in connection with
qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Securityholder.

                  16.      DEFAULTS AND REMEDIES

                  Under the Indenture, Events of Default include (i) default for
30 days in payment of interest on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon redemption pursuant to paragraph 5
or 6 of the Securities, upon required purchase, upon acceleration or otherwise,
or failure by the Company or the Guarantors to redeem or purchase Securities
when required; (iii) failure by the Company to comply with other agreements in
the Indenture or the Securities, in certain cases subject to notice and lapse of
time; (iv) certain accelerations (including failure to pay within any grace
period after final maturity) of other Indebtedness of Holdings, the Company or
the Owners if the amount accelerated (or so unpaid) exceeds $5.0 million; (v)
certain events of bankruptcy or insolvency with respect to Holdings, the Company
or the Owners; (vi) certain judgments or decrees for the payment of money in
excess of $5.0 million, (vii) certain events or defaults with respect to the
Guarantees or the Security Agreements and (ix) the failure by the Designated
Owners to hold certain prescribed percentages of Voting Stock and Capital Stock
of Holdings. If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Securities may declare all
the Securities to be due and payable immediately. Certain events of bankruptcy
or insolvency are Events of Default which will result in the Securities being
due and payable immediately upon the occurrence of such Events of Default.

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


                  17.      TRUSTEE DEALINGS WITH THE COMPANY

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


                  18.      NO RECOURSE AGAINST OTHERS

                  A director, officer, employee or stockholder, as such, of the
Company, Holdings, the Owners or the Trustee shall not have any liability for
any obligations of the Company, Holdings or the Owners under the Securities or
the Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation. By accepting a Security, each Securityholder
waives and releases all such liability. The waiver and release are part of the
consideration for the issue of the Securities.

  __% Second Priority Ship Mortgage Notes Due 2007

                  1.       INTEREST

                  NAVIGATOR GAS TRANSPORT PLC, an Isle of Man public limited
company (such corporation, and its successors and assigns under the Indenture
hereinafter referred to, being herein called the "Company"), promises to pay
interest on the principal amount of this Security at the rate per annum shown
above; provided, however, that if a Registration Default (as defined in the
Registration Rights Agreement) occurs, additional interest will accrue on this
Security at a rate of 0.50% per annum from and including the date on which any
such Registration Default shall occur to but excluding the date on which all
Registration Defaults have been cured. The Company will pay interest in cash
semiannually on June 30 and December 31 of each year, commencing December 31,
1997, except that at the option of the Company, on any Interest Payment Date
following the delivery of the first Vessel, to the extent cash available for
distribution to Holders of Securities on such date is insufficient to pay all
accrued and unpaid interest on the Securities on such date, the Company may pay
such interest by issuing additional Securities having an aggregate principal
amount equal to the amount of such deficiency, provided that the Company may not
issue more than $20,900,000 aggregate principal amount of such additional
Securities. Interest on the Securities will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from August 7,
1997. Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus _% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

                  2.       METHOD OF PAYMENT

                  The Company will pay interest on the Securities (except
defaulted interest) to the Persons who are registered holders of Securities at
the close of business on the June 15 or December 15 next preceding the interest
payment date even if Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying
Agent to collect principal payments. The Company will pay principal and interest
in money of the United States that at the time of payment is legal tender for
payment of public and private debts. Payments in respect of the Securities
represented by a Global Security (including principal, premium and interest)
will be made by wire transfer of immediately available funds to the accounts
specified by The Depository Trust Company. The Company will make all payments in
respect of a certificated Security (including principal, premium and interest)
by mailing a check to the registered address of each Holder thereof; provided,
however, that payments on a certificated Security will be made by wire transfer
to a U.S. dollar account maintained by the payee with a bank in the United
States if such Holder elects payment by wire transfer by giving written notice
to the Trustee or the Paying Agent to such effect designating such account no
later than 30 days immediately pre ceding the relevant due date for payment (or
such other date as the Trustee may accept in its discretion).

                  3.       PAYING AGENT AND REGISTRAR

                  Initially, The Chase Manhattan Bank, a New York banking
corporation ("Trustee"), will act as Paying Agent and Registrar. The Company may
appoint and change any Paying Agent, Registrar or co-registrar without notice.
The Company or any of its



                                        3

<PAGE>




domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent,
Registrar or co-registrar.

                  4.       INDENTURE

                  The Company issued the Securities under an Indenture dated as
of August 1, 1997 ("Indenture"), among the Company, Holdings, the Guarantors and
the Trustee. The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as in effect on the date of the Indenture
(the "Act"). Terms defined in the Indenture and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
such terms, and Securityholders are referred to the Indenture and the Act for a
statement of those terms.

                  The Securities are general secured obligations of the Company
initially limited to $87,000,000 aggregate principal amount (subject to Section
2.06 of the Indenture and subject to the issuance of up to $20,900,000 aggregate
principal amount of Securities under the circumstances described in paragraph 1
above). The Indenture limits (i) the incurrence of additional debt by the
Company and the Owner, (ii) the payment of dividends on capital stock of the
Company and the purchase, redemption or retirement of capital stock or
subordinated indebtedness, (iii) investments, (iv) certain liens and
sale/leaseback transactions, (v) certain transactions with affiliates, (vi)
sales of assets, (vii) the issuance or sale of capital stock of subsidiaries and
(viii) certain consolidations, mergers and transfers of assets. The Indenture
also prohibits certain restrictions on distributions from the Owners.

                  5.       OPTIONAL REDEMPTION

                  Except as set forth in the next two paragraphs, the Securities
may not be redeemed prior to June 30, 2002. On and after that date, the Company
may redeem the Securities in whole at any time or in part from time to time at
the following redemption prices (expressed in percentages of principal amount),
plus accrued interest to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on the related
Interest Payment Date):

                  if redeemed during the 12-month period beginning June 30,

         Period                                             Percentage

                  If, as a result of any change in or any amendment to the laws,
regulations or published tax rulings of the Isle of Man or any Successor
Jurisdiction, or of any political subdivision or taxing authority thereof or
therein, or any change in the official administration, application or
interpretation of such laws, regulations or published tax rulings either
generally or in relation to any particular Securities, which change in official
administration, application or interpretation shall not have been available to
the public prior to such issue date and is notified to the Company or the
relevant Owners, as the case may be, on or after such issue date, it is
determined by the Company or the relevant Owners, as the


                          
                                        4

<PAGE>




case may be, that the Company or the relevant Owners, as the case may be, would
be required to pay, any Additional Amounts pursuant to the Indenture or the
terms of any Security in respect of interest on the next succeeding Interest
Payment Date (assuming, in the case of the Owners, that a payment in respect of
such interest were required to be made by the relevant Owners under the
Guarantees on such Interest Payment Date), and that such obligation cannot be
avoided by the Company or the relevant Owners taking reasonable measures
available to it, the Company or the relevant Owners, as the case may be, may, at
its option, redeem all (but not less than all) the Securities in respect of
which such Additional Amounts would be so payable at any time, at a redemption
price equal to 100% of the principal amount thereof plus accrued interest to the
date fixed for redemption; provided, however, that (a) no such notice of
redemption may be given earlier than 60 days prior to the earliest date on which
the Company or the relevant Owners, as the case may be, would be obligated, or
is substantially likely to be obligated, to pay such Additional Amounts were a
payment in respect of the Securities or the Guarantees, as the case may be, then
due, and (b) at the time any such redemption notice is given, such obligation,
or substantial likelihood, to pay such Additional Amounts must remain in effect.

                  In addition, at any time and from time to time prior to June
30, 2000, the Company may redeem up to 35% of the aggregate principal amount of
Securities with the proceeds of one or more Public Equity Offerings (with the
cash proceeds thereof to the extent actually contributed to the Company)
following which there is a Public Market, at a redemption price (expressed as a
percentage of principal amount) of 112% plus accrued interest to the redemption
date (subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date); provided, however,
that at least $45 million aggregate principal amount of the Securities and $100
million aggregate principal amount of the First Priority Notes must remain
outstanding after each such redemption.

                  6.       MANDATORY REDEMPTION

                  In the event an Owner elects to terminate its Building
Contract because of a material breach thereof by the Builders (including a
failure to pay liquidated damages for any delay in the delivery of the related
Vessel), the Securities will be subject to mandatory redemption in part, on a
pro rata basis, in an aggregate principal amount equal to the Allocated
Principal Amount of the Securities for such Vessel and for each other Vessel
that has not been accepted by its related Owner as of the date of such
termination, at a redemption price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest to and including the date of
redemption (subject to the right of a Holder of record on the relevant record
date to receive interest due on the relevant Interest Payment Date), upon the
earlier to occur of (a) the receipt of the Refund Amount with respect to the
related Building Contract(s) and (b) 60 days after the termination of such
Building Contract(s) by the related Owner(s).

                  If a Vessel is subject to Total Loss, the Securities will be
subject to mandatory redemption in part, on a pro rata basis, in an aggregate
principal amount equal to the Allocated Principal Amount of the Securities for
such Vessel, at a redemption price equal to 101% of the principal amount
thereof, plus accrued and unpaid interest to the date of redemption (subject to
the right of a Holder of record on the relevant record date to receive interest
due on the relevant Interest Payment Date), upon the earlier to occur of (a) the
receipt of the Insurance Proceeds with respect to such Total Loss and (b) 60
days after such Total Loss was deemed to have occurred.

<PAGE>




                  7.       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 of Securities to be
redeemed at his registered address. Securities in denominations larger than
$1,000 may be redeemed in part but only in whole multiples of $1,000. If money
sufficient to pay the redemption price of and accrued interest on all Securities
(or portions thereof) to be redeemed on the redemption date is deposited with
the Paying Agent on or before the redemption date, on and after such date
interest ceases to accrue on such Securities (or such portions thereof) called
for redemption.

                  8.       OFFERS TO PURCHASE

                  Commencing on the first Available Cash Payment Date and on
each Available Cash Payment Date thereafter, the Company will be required to the
extent of Available Cash on such Available Cash Payment Date, to make an
Available Cash Offer to each Holder of Securities to purchase such Holder's
Securities in whole or in part, at a price equal to 102% of the principal amount
thereof plus accrued and unpaid interest to the date of purchase (subject to the
right of Holders of record on the relevant record date to receive interests due
on the related Interest Payment Date) as provided in, and subject to the terms
of, the Indenture. Upon a Change of Control, any Holder of Securities will have
the right to cause the Company to purchase all or any part of the Securities of
such Holder at a purchase price equal to 101% of the principal amount of the
Securities to be purchased plus accrued interest to the date of repurchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the related Interest Payment Date) as provided in, and
subject to the terms of, the Indenture, provided that the Company shall purchase
any and all First Priority Notes validly tendered pursuant to a change of
control offer made pursuant to the First Priority Note Indenture prior to
purchasing any Securities validly tendered pursuant to such Change of Control
Offer.

                  9.       GUARANTEE

                  The payment by the Company of the principal of, and premium
and interest on, the Securities is fully and unconditionally guaranteed on a
joint and several senior basis by the Owners.

                  10.      SECURITY

                  The Securities will initially be secured by the Collateral
delivered on the Issue Date. Upon the occurrence of a Delivery Date with respect
to a Vessel the Securities will thereafter be secured by a first priority ship
mortgage on such Vessel and all other Collateral delivered on the Delivery Date
of such Vessel. The Securities will also have the benefit of the Letter of
Credit.

                  11.      DENOMINATIONS; TRANSFER; EXCHANGE

                  The Securities are in registered form without coupons in
denominations of $1,000 and whole multiples of $1,000. A Holder may transfer or
exchange Securities in accordance with the Indenture. The Registrar may require
a Holder, among other things, to furnish appropriate endorsements or transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture. The Registrar need not register the transfer of or exchange any
Securities selected for redemption (except, in the case of a Security to be


                          
                                        6

redeemed in part, the portion of the Security not to be redeemed) or any
Securities for a period of 15 days before a selection of Securities to be
redeemed or 15 days before an interest payment date.

                  12.      PERSONS DEEMED OWNERS

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

                  13.      UNCLAIMED MONEY

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


                  14.      DISCHARGE AND DEFEASANCE

                  Subject to certain conditions, the Company at any time may
terminate some or all of its and the Guarantors' obligations under the
Securities, the Security Agreements and the Indenture if the Company deposits
with the Trustee money or U.S. Government Obligations for the payment of
principal and interest on the Securities to redemption or maturity, as the case
may be.

                  15.      AMENDMENT, WAIVER

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount of the Securities and (ii)
any default or noncompliance with any provision may be waived with the written
consent of the Holders of a majority in principal amount of the Securities.
Subject to certain exceptions set forth in the Indenture, without the consent of
any Securityholder, the Company, the Guarantors and the Trustee may amend the
Indenture, the Security Agreements or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 5 of the Indenture,
or to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add additional guarantees with respect to the
Securities or to provide additional security for the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company or
the Guarantors, or to comply with any request of the SEC in connection with
qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Securityholder.

                  16.      DEFAULTS AND REMEDIES

                  Under the Indenture, Events of Default include (i) default for
30 days in payment of interest on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon redemption pursuant to paragraph 5
or 6 of the Securities, upon required purchase, upon acceleration or otherwise,
or failure by the Company or the Guarantors to redeem or purchase Securities

lapse of time; (iv) certain accelerations (including failure to pay within any
grace period after final maturity) of other Indebtedness of Holdings, the

million; (v) certain events of bankruptcy or insolvency with respect to
Holdings, the Company or the Owners; (vi) certain judgments or decrees for the
payment of money in excess of $5.0 million, (vii) certain events or defaults

may declare all the Securities to be due and payable immediately. Certain events
of bankruptcy or insolvency are Events of Default which will result in the
Securities being due and payable immediately upon the occurrence of such Events
of Default.

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

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

                  18.      NO RECOURSE AGAINST OTHERS

                  A director, officer, employee or stockholder, as such, of the
Company, Holdings, the Owners or the Trustee shall not have any liability for
any obligations of the Company, Holdings or the Owners under the Securities or
the Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation. By accepting a Security, each Securityholder
waives and releases all such liability. The waiver and release are part of the
consideration for the issue of the Securities.

                  19.      AUTHENTICATION

                  This Security shall not be valid until an authorized signatory

thereof fall below the ratings that are indicated in such clause, either the
Company or the Majority Secured Creditors shall direct the Collateral Agent in
writing to re-invest such amounts in another Temporary Cash Investment. In order

shall not be obligated to, adjust subsequent allocations and distributions
thereunder upon written confirmation from the Company of the amount of such

Capital Draws and Final Draws under the Letter of Credit as contemplated by the
terms of the Indentures, and the Company hereby agrees to deliver to the
Collateral Agent any certificates requested by the Collateral Agent to enable
the Collateral Agent to take such action. In furtherance of the foregoing, the
Collateral Agent is hereby directed and authorized to deliver a Drawing
Certificate to CSFB from time to time in connection with (a) Interest Draws

effectuate and preserve the security of the Secured Creditors and all rights of
the Collateral Agent. Without limiting the foregoing, the Collateral Agent is

         indentures, financing statements, continuation statements or other
         instruments of further assurance as is necessary to maintain the Lien

         (ii) stating that, in the opinion of such counsel, no such action is

Date as follows:

                  (a) such Grantor has good and valid rights in and title to the
Collateral with respect to which it has purported to grant a security interest
hereunder and has full power and authority to grant to the Collateral Agent the
security interest in such Collateral pursuant hereto and to execute, deliver and
perform its obligations in accordance with the terms of this Agreement, without
the consent or approval of any other person other than any consent or approval
which has been obtained;


<PAGE>

                                                                              32



                  (b) the security interest constitutes a legal and valid
security interest in all the Collateral securing the payment and performance of
the Obligations; the security interest is and shall be prior to any other Lien
on any of the Collateral, other than Permitted Liens; and

                  (c) such Grantor owns the Collateral free and clear of any
Lien, except for Permitted Liens; has not filed or consented to the filing of
(a) any financing statement or analogous document under the Uniform Commercial
Code or any other applicable laws covering any Collateral other than those that
may be filed in favor of the Collateral Agent pursuant to this Agreement, or (b)
any assignment in which it assigns any Collateral or any security agreement or
similar instrument covering any Collateral with any foreign governmental,
municipal or other office, which financing statement or analogous document is
still in effect, except, in each case, for Permitted Liens.

                  SECTION 4.4. PROTECTION OF THE TRUST ESTATE. The Collateral
Agent shall have the power to enforce the obligations of the Grantors under this
Agreement and under the other Security Agreements, to the extent permitted
hereunder and thereunder, to institute and maintain such suits and proceedings
as it may deem expedient to prevent any impairment of the Collateral under any
of the Security Agreements and in the profits, rents, revenues and other income
arising therefrom, including the power to institute and maintain suits or
proceedings to restrain the enforcement of or compliance with any legislative or
other governmental enactment, rule or order that may be unconstitutional or
otherwise invalid if the enforcement of, or compliance with, such enactment,
rule or order would impair any Collateral or be prejudicial to the interests of
the Secured Creditors.

                  SECTION 4.5. RELEASE OF LIEN. (a) So long as no Event of
Default has occurred and is continuing, Collateral may be released from the Lien
and security created by this Agreement and the other Security Agreements, as the
case may be, at any time or from time to time in accordance with the express
provisions of the Debt Instruments, this Agreement, the other Security
Agreements and the Trust Indenture Act. In the case of Collateral consisting of
cash or Temporary Cash Investments which are permitted to be withdrawn from the
Trust Accounts and paid to Persons other than the Secured Creditors pursuant to
Article III, such Collateral shall be released as provided herein without the
need for any Officer's Certificate, Opinion of Counsel, release, waiver or other
action.

                                                                              33



                  (b) Upon the request of the Grantors and pursuant to an
Officer's Certificate and an Opinion of Counsel certifying that all conditions
precedent hereunder have been met (to be provided at the sole cost and expense
of the Grantors) and upon the satisfaction of such conditions precedent
hereunder, the Collateral Agent shall release (i) any portion of the Collateral
as to the release of which the consent of the Representative of each class of
Secured Creditors (including CSFB, the Funding Bank and each of the
Participating Banks) has been obtained, and (ii) all Collateral upon discharge
of all Obligations under the Debt Instruments and the Security Agreements.

                  (c) Upon receipt of such Officer's Certificate and Opinion of
Counsel described in paragraph (b) above, the Collateral Agent shall execute,
deliver or acknowledge any necessary or proper instruments of termination,
satisfaction or release to evidence the release of any Collateral permitted to
be released pursuant to this Agreement or this Agreement and the other Security
Agreements, as the case may be. Whenever Collateral is to be released pursuant
to this Section 4.5, the Collateral Agent shall execute any document or
termination statement reasonably necessary to release the Lien of this Agreement
or this Agreement and the other Security Agreements, as the case may be.

                  (d) The release of any Collateral from the terms of this
Agreement or this Agreement and the other Security Agreements, as the case may
be, will not be deemed to impair the Lien created by this Agreement in
contravention of the provisions hereof. To the extent applicable, the Grantors
shall cause Section 314(d) of the Trust Indenture Act relating to the release of
property from the Lien arising out of the Security Agreements to be complied
with. Any certificate or opinion required by Section 314(d) of the Trust
Indenture Act may be made by any Responsible Officer of the Company; PROVIDED
that to the extent required by Section 314(d) of the Trust Indenture Act, any
such certificate or opinion shall be made by an independent engineer, appraiser
or other expert (as such terms are set forth in Section 314(d) of the Trust
Indenture Act), who is not an Affiliate of the Company or any other Grantor.

                  (e) Notwithstanding the other provisions of this Section 4.5,
if no Event of Default has occurred and is continuing, upon the Collateral
Agent's receipt of the Total Loss Payment for a Vessel, together with all other
amounts owing under the Debt Instruments and the Security Agreements in respect
of such Vessel, the Collateral Agent shall (i) release such Vessel and any
portion of the Collateral delivered in connection with such Vessel from the Lien
of this Agreement and (ii) release the Company and the related 


<PAGE>

                                                                              34



Owner from any and all of its obligations hereunder, under the Debt Instruments
and the related Security Agreements to the extent they arise in connection with
such Vessel.

                  SECTION 4.6. LIMITATION ON COLLATERAL AGENT'S DUTY IN RESPECT
OF COLLATERAL. Beyond its duties as to the custody thereof expressly provided
herein or in any other Security Agreement and to account to the Secured
Creditors and the Grantors for moneys and other property received by it under
any Security Agreement, the Collateral Agent shall not have any duty to the
Secured Creditors or the Grantors as to any Collateral in its possession or
control or in the possession or control of any of its agents or nominees, or any
income thereon or as to the preservation of rights against prior parties or any
other rights pertaining thereto. The Collateral Agent shall be deemed to have
exercised reasonable care in the custody of the Collateral in its possession if
the Collateral is accorded treatment substantially equal to that which it
accords its own property.

                  SECTION 4.7. DELIVERY OF LETTER OF CREDIT. On the date hereof,
the Company shall deliver to the Collateral Agent, for the benefit of the
Trustees, a Letter of Credit substantially in the form attached hereto as

Grantors hereby appoint the Collateral Agent as the Grantors' attorney-in-fact,
with full authority in the place and stead of the Grantors and in the name of
the Grantors or otherwise, from time to time in the Collateral Agent's
discretion but only after the occurrence and during the continuance of an Event
of Default, to take any action and to execute any instrument which the
Collateral Agent may deem necessary or advisable in order to accomplish the
purposes of this Article IV, including to receive, endorse and collect all
instruments made payable to the Grantors representing any dividend, interest
payment or other distribution in respect of the Collateral or any part thereof
and to give full discharge for the same. This power, being coupled with an
interest, is irrevocable.

                  SECTION 4.9. COLLATERAL AGENT MAY PERFORM. If the Grantors
fail to perform any agreement contained in this Article IV, the Collateral Agent
may itself perform, or cause performance of, such agreement, and the expenses of
the Collateral Agent incurred in connection therewith shall be payable by the
Grantors under Section 7.3.

                  SECTION 4.10.  APPLICATION OF PROCEEDS.  Upon the
occurrence and during the continuance of an Event of Default
and after the acceleration of any Secured Debt pursuant to

the Debt Instruments (so long as such acceleration has not been rescinded), any
cash held by the Collateral Agent as Collateral and all cash proceeds received
by the Collateral Agent in respect of any sale of, collection from, or other
realization upon, all or any part of the Collateral, shall be held in the
Termination Account and shall be distributed by the Collateral Agent in the
order of priority specified with respect to amounts on deposit in the Trust
Accounts in Section 3.4.

                  SECTION 4.11. CONTINUING LIEN. Except as provided in Section
4.5, this Agreement shall create a continuing Lien on the Collateral that shall
(i) remain in full force and effect until payment in full of the Obligations,
(ii) be binding upon the Grantors and their successors and assigns and (iii)
enure to the benefit of the Collateral Agent and its successors, transferees and
assigns.

                  property and proceeds from time to time received, receivable
                  or otherwise distributed in respect of or in exchange for any

blank, all in form and substance satisfactory to the Collateral Agent. The
Collateral Agent shall have the right, at any time after the occurrence and

                  SECTION 6.3.  REPRESENTATIONS AND WARRANTIES.
Each of the Pledgors hereby represents and warrants on the
Issue Date as follows:

                  (a) it is the record owner of the Pledged Shares listed beside
         its name and described on Schedule I hereto, free and clear of any
         Lien, except for the Lien created by this Agreement;

                  (b)  it has full corporate power, authority and
         legal right to pledge all the Pledged Collateral
         pledged by it pursuant to this Agreement;

                  (c) the Pledged Shares listed beside its name and described on
         Schedule I hereto have been duly authorized and are validly issued,
         fully paid and nonassessable;

                  (d) its pledge in accordance with the terms of this Agreement
         creates a valid and perfected first priority Lien on the Pledged
         Collateral pledged by it securing the payment and performance of the
         Obligations;

                  (e) in the case of the Company, the shares listed beside its
         name and described in Schedule I hereto represent 100.0% of the shares
         of Capital Stock of the Owners and, in the case of Holdings, the shares
         listed beside its name and described in Schedule I hereto represent
         100.0% of the shares of Capital Stock of the Company in which Holdings
         holds a beneficial interest and represent 50% of the record interest of
         all shares of Capital Stock of the Company; and

                  (f) in the case of the Company, there are no existing options,
         warrants, calls or commitments of any character relating to any
         authorized and unissued Capital Stock of any Owners and, in the case of
         Holdings, there are no existing options, warrants,


<PAGE>

                                                                              40



         calls or commitments of any character relating to any authorized and
         unissued Capital Stock of the Company.

                  SECTION 6.4. FURTHER ASSURANCES. The Pledgors agree that at
any time and from time to time, at their own expense, the Pledgors will promptly
execute and deliver all further instruments and documents and take all further
action that may be necessary or that the Collateral Agent may reasonably request
in order to perfect and protect any Lien granted or purported to be granted
hereby or to enable the Collateral Agent to exercise and enforce its rights and
remedies hereunder with respect to any Pledged Collateral. The Company further
agrees that it will not issue any additional shares of its Capital Stock other
than such shares that may be issued to Holdings. Without limiting the foregoing,
the Pledgors shall, (i) at the time of the issuance by an Owner or the Company,
as the case may be, of any shares of Capital Stock after the Issue Date, deliver
100.0% of such shares to the Collateral Agent as Pledged Collateral and provide
to the Collateral Agent a revised Schedule I hereto, and (ii) at the time of any
release of Pledged Shares pursuant to Section 4.4, provide to the Collateral
Agent a revised Schedule I hereto. Any such revised Schedule I shall reflect any
changes made necessary by the applicable acquisition or release, at which time
the Pledgors shall be deemed to make their representations and warranties set
forth in paragraphs (a) through (f) of Section 6.3 with respect to such Schedule
I, as so revised.

                  SECTION 6.5. DIVIDENDS; VOTING RIGHTS; RELEASE OF PLEDGED
COLLATERAL. (a) The Collateral Agent shall be entitled to receive and retain as
Collateral all dividends paid and distributions made in respect of the Pledged
Shares, whether so paid or made before or after any Default. Any such dividends
shall, if received by the Pledgors, be received in trust for the benefit of the
Collateral Agent, be segregated from the other property or funds of the Pledgors
and be forthwith delivered to the Collateral Agent as Collateral in the same
form as so received (with any necessary endorsement). Any cash dividends or
distributions delivered to or otherwise held by the Collateral Agent pursuant to
this Section 6.5, and any other cash constituting Collateral delivered to the
Collateral Agent, shall be invested, at the written direction of the Pledgors,
by the Collateral Agent in Temporary Cash Investments.

                  (b) As long as no Default shall have occurred and be
continuing and until written notice thereof from the Collateral Agent to the
Pledgors, the Pledgors shall be entitled to exercise any and all voting and
other consensual rights relating to Pledged Shares or any part thereof for any
purpose; PROVIDED, HOWEVER, that no vote shall be cast,


<PAGE>

                                                                              41



and no consent, waiver or ratification given or action taken, which would be
inconsistent with or violate any provision of this Agreement, the other Security
Agreements or the Debt Instruments.

                  (c) Upon the occurrence and during the continuance of a
Default, all rights of the Pledgors to exercise the voting and other consensual
rights that it would otherwise be entitled to exercise pursuant to Section
6.5(b) shall cease upon notice from the Collateral Agent to the Pledgors and
upon the giving of such notice all such rights shall thereupon be vested in the
Collateral Agent who shall thereupon have the sole right to exercise such voting
and other consensual rights.

                  (d) In order to permit the Collateral Agent to exercise the
voting and other consensual rights which it may be entitled to exercise pursuant
to Section 6.5(c), and to receive all dividends and distributions which it may
be entitled to receive under Section 6.5(a), the Pledgors shall, if necessary,
upon written notice of the Collateral Agent, from time to time execute and
deliver to the Collateral Agent such instruments as the Collateral Agent may
reasonably request.

                  (e) Notwithstanding anything to the contrary in this Article
VI, upon the request of the Grantors and pursuant to an Officer's Certificate
and an Opinion of Counsel certifying that all conditions precedent hereunder
have been met (to be provided at the sole cost and expense of the Grantors) and
upon the satisfaction of such conditions precedent hereunder, the Collateral
Agent shall release (i) any portion of the Collateral as to the release of which
the consent of the Representative of each class of Secured Creditors (including
CSFB, the Funding Bank and each of the Participating Banks) has been obtained,
and (ii) all Collateral upon satisfaction of all Obligations under the Debt
Instruments and the Security Agreements. At the request of the Pledgors, the
Collateral Agent shall execute and deliver appropriate instruments evidencing
any release pursuant to this Section 6.5(e).

                  SECTION 6.6. COLLATERAL AGENT APPOINTED ATTORNEY- IN-FACT. The
Pledgors hereby appoint the Collateral Agent as the Pledgors' attorney-in-fact,
with full authority in the place and stead of the Pledgors and in the name of
the Pledgors or otherwise, from time to time in the Collateral Agent's
discretion but only after the occurrence and during the continuance of an Event
of Default, to take any action and to execute any instrument which the
Collateral Agent may deem necessary or advisable in order to accomplish the
purposes of this Article VI, including to receive, endorse


<PAGE>

                                                                              42



and collect all instruments made payable to the Pledgors representing any
dividend, interest payment or other distribution in respect of the Pledged
Collateral or any part thereof and to give full discharge for the same. This
power, being coupled with an interest, is irrevocable.

                  SECTION 6.7. COLLATERAL AGENT MAY PERFORM. If the Pledgors
fail to perform any agreement contained in this Article VI, the Collateral Agent
may itself perform, or cause performance of, such agreement, and the expenses of
the Collateral Agent incurred in connection therewith shall be payable by the
Pledgors under Section 7.3.

                  SECTION 6.8. REMEDIES UPON EVENT OF DEFAULT. If any Event of
Default shall have occurred and be continuing, the Collateral Agent may exercise
in respect of the Pledged Collateral, in addition to other rights and remedies
provided for herein or otherwise available to it, all the rights and remedies
provided a secured party upon the default of a debtor under the Uniform
Commercial Code at that time, and the Collateral Agent may also, without notice
except as specified below, sell the Pledged Collateral or any part thereof in
one or more parcels at public or private sale, at any exchange, broker's board
or at any of the Collateral Agent's offices or elsewhere, for cash, on credit or
for future delivery, upon such terms as the Collateral Agent may determine to be
commercially reasonable, and the Collateral Agent or any other Secured Party may
be the purchaser of any or all the Pledged Collateral so sold and thereafter
hold the same, absolutely, free from any right or claim of whatsoever kind. The
Pledgors agree that, to the extent notice of sale shall be required by law, at
least 10 days' notice to the Pledgors of the time and place of any public sale
or the time after which any private sale is to be made shall constitute
reasonable notification within the meaning of Section 9-504(3) of the Uniform
Commercial Code. The Collateral Agent shall not be obligated to make any sale of
Pledged Collateral regardless of notice of sale having been given. The
Collateral Agent may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned. The
Collateral Agent shall incur no liability as a result of the sale of the Pledged
Collateral, or any part thereof, at any private sale conducted in a commercially
reasonable manner. The Pledgors hereby waive any claims against the Collateral
Agent arising by reason of the fact that the price at which any Pledged
Collateral may have been sold at such a private sale was less than the price
which might have been obtained at a public sale, even if the Collateral Agent
accepts the first offer received and does not offer such Pledged Collateral to
more than one offeree.


<PAGE>

                                                                              43



                  The Pledgors recognize that, by reason of certain prohibitions
contained in the Securities Act and applicable state securities laws, the
Collateral Agent may be compelled, with respect to any sale of all or any part
of the Pledged Collateral, to limit purchasers to those who will agree, among
other things, to acquire such securities for their own account, for investment,
and not with a view to the distribution or resale thereof. The Pledgors
acknowledge and agree that any such sale may result in prices and other terms
less favorable to the seller than if such sale were a public sale without such
restrictions and, notwithstanding such circumstances, agree that any such sale
shall be deemed to have been made in a commercially reasonable manner. The
Collateral Agent shall be under no obligation to delay the sale of any of the
Pledged Collateral for the period of time necessary to permit the Pledgors to
register such securities for public sale under the Securities Act, or under
applicable state securities laws, even if the Pledgors would agree to do so.

                  SECTION 6.9. APPLICATION OF PROCEEDS. Upon the occurrence and
during the continuance of an Event of Default and after the acceleration of any
Secured Debt pursuant to the Debt Instruments (so long as such acceleration has
not been rescinded), any cash held by the Collateral Agent as Pledged Collateral
and all cash proceeds received by the Collateral Agent in respect of any sale
of, collection from, or other realization upon, all or any part of the Pledged
Collateral, shall be held in the Termination Account and shall be distributed by
the Collateral Agent in the order of priority specified with respect to amounts
on deposit in the Trust Accounts in Section 3.4.

                  SECTION 6.10. CONTINUING LIEN. Except as provided in Section
6.5, this Agreement shall create a continuing Lien on the Pledged Collateral
that shall (i) remain in full force and effect until payment in full of the
Obligations, (ii) be binding upon the Pledgors and their successors and assigns
and (iii) enure to the benefit of the Collateral Agent and its successors,
transferees and assigns.

                  SECTION 6.11. CERTIFICATES AND OPINIONS. The Pledgors shall
comply with (a) TIA ss. 314(b), relating tO Opinions of Counsel regarding the
Lien of this Agreement and (b) TIA ss. 314(d), relating to the release of
Pledged Collateral from the Lien of this Agreement and Officers' Certificates or
other documents regarding fair value of the Pledged Collateral, to the extent
such provisions are applicable. Any certificate or opinion required by TIA ss.
314(d) may be executed and delivered by Officers of the Pledgor to the extent
permitted by TIA ss. 314(d).

                                                                              44



                  SECTION 6.12. ADDITIONAL AGREEMENTS. The Pledgors agree that,
upon the occurrence and during the continuance of a Default, they will, at any
time and from time to time, upon the written request of the Collateral Agent,
use their best efforts to take or to cause the issuer of the Pledged Shares and
any other securities distributed in respect of the Pledged Shares (collectively
with the Pledged Shares, the "Pledged Securities") to take such action and
prepare, distribute or file such documents, as are required or advisable in the
reasonable opinion of counsel for the Collateral Agent to permit the public sale
of such Pledged Securities. The Pledgors further agree to indemnify, defend and
hold harmless the Collateral Agent, each Holder, CSFB, any underwriter and their
respective officers, directors, affiliates and controlling persons from and
against all loss, liability, expenses, costs of counsel (including reasonable
fees and expenses of legal counsel to the Collateral Agent), and claims
(including the costs of investigation) that they may incur insofar as such loss,
liability, expense or claim arises out of or is based upon any alleged untrue
statement of a material fact contained in any prospectus (or any amendment or
supplement thereto) or in any notification or offering circular, or arises out
of or is based upon any alleged omission to state a material fact required to be
stated therein or necessary to make the statements in any thereof not
misleading, except insofar as the same may have been caused by any untrue
statement or omission based upon information furnished in writing to the
Pledgors or the issuer of such Pledged Securities by the Collateral Agent or any
Holder expressly for use therein. The Pledgors further agree, upon such written
request referred to above, to use their best efforts to qualify, file or
register, or cause the issuer of such Pledged Securities to qualify, file or
register, any of the Pledged Securities under the Blue Sky or other securities
laws of such states as may be requested by the Collateral Agent and keep
effective, or cause to be kept effective, all such qualifications, filings or
registrations. The Pledgors will bear all costs and expenses of carrying out
their obligations under this Section 6.13. The Company agrees to record all
loans and advances made by it to the Owners (all of which shall be evidenced by
the Intercompany Note), and all repayments thereof, in its books and records,
such books and records constituting prima facie evidence and the accuracy of the
information contained therein. The Pledgors acknowledge that there is no
adequate remedy at law for failure by them to comply with the provisions of this
Section 6.13 and that such failure would not be adequately compensable in
damages, and therefore agree that their agreements contained in this Section
6.13 may be specially enforced.

                                   ARTICLE VII

                              THE COLLATERAL AGENT

                  SECTION 7.1. NATURE OF DUTIES. The Collateral Agent shall be
responsible for taking only such actions as are expressly set forth herein or
any instructions received from any Representative, pursuant to the terms hereof
and of any other Security Agreement and no implied duties or obligations shall
be read into this Agreement or any such instructions or other Security
Agreement. Notwithstanding any provision in any other Security Agreement,
neither the Collateral Agent nor any of its officers, directors, employees or
agents shall be liable for any claims, losses, damages, penalties, actions,
judgments, suits, liabilities, obligations, costs or expenses of any kind or
nature whatsoever resulting from any action the Collateral Agent takes or omits
to take under any Security Agreement or in connection therewith, unless caused
by its or their negligence, bad faith or wilful misconduct. The Collateral Agent
may perform any of its duties hereunder by or through its agents or employees.

                  The Collateral Agent shall at all times be entitled to follow
instructions of the Senior Representative delivered or deemed to be delivered in
accordance with this Agreement, notwithstanding the fact that the same Person
may be acting in both such capacities hereunder, and all Secured Creditors shall
be bound by any action taken by the Collateral Agent in accordance therewith.

                  SECTION 7.2. LACK OF RELIANCE ON THE COLLATERAL AGENT. The
Collateral Agent shall have no duty or responsibility, either initially or on a
continuing basis, to provide any Representative or any Secured Creditor with any
credit or other information with respect to the Company or any of its Affiliates
whether coming into its possession before the date hereof or at any time or
times thereafter, except as specifically instructed by any Representative.

                  SECTION 7.3. COMPENSATION AND INDEMNIFICATION. (a) The Company
agrees to pay to the Collateral Agent, from time to time upon demand, reasonable
compensation for the services of the Collateral Agent hereunder and under the
other Security Agreements and all reasonable fees, costs and expenses of the
Collateral Agent (including the reasonable expenses, fees and disbursements of
counsel, agents and experts of the Collateral Agent) incurred by the Collateral
Agent in connection with (i) the preparation, execution, delivery,
administration, modification, amendment or termination of this Agreement, each
Security Agreement or the enforcement of any of the provisions hereof or
thereof,


<PAGE>

                                                                              46



(ii) the custody or preservation and protection of, or the sale of, collection
from, or other realization upon, any of the Collateral pursuant to this
Agreement or any other Security Agreement, (iii) the preservation, protection,
defense, exercise or enforcement of any of the rights of the Collateral Agent
under this Agreement or the other Security Agreements and in and to the
Collateral arising under applicable law or (iv) the failure by the Company to
perform or observe any of the provisions of this Agreement or any other Security
Agreement. When the Collateral Agent incurs expenses or renders services after
an Event of Default specified in Sections 6.01(7) or 6.01(8) of the Indentures,
such expenses and the compensation for such services are intended to constitute
expenses of administration under any Bankruptcy Law.

                  (b) The Company hereby agrees to indemnify the Collateral
Agent, each Representative and each Secured Creditor for, and hold each of them
harmless against, any future claim for liability for any stamp, transfer or
other similar tax and any penalties or interest with respect thereto, which may
be assessed, levied or collected by any jurisdiction in connection with any
Security Agreement or any Collateral; PROVIDED, HOWEVER, that the Company shall
not be obligated under this paragraph (b) in respect of any income tax or any
tax imposed in connection with any transfer of securities.

                  (c) The Company hereby agrees to pay or to reimburse the
Collateral Agent for any and all amounts in respect of all search, filing,
recording and registration fees, excise taxes and other similar imposts which
may be payable or determined to be payable in respect of the execution,
delivery, performance and enforcement of each Security Agreement.

                  (d) The Company hereby agrees to indemnify the Collateral
Agent (including within such term for purposes of this Section 7.3, its
officers, directors, employees and agents) for, and hold it and them harmless,
in its capacity as Collateral Agent, against, any and all claims, demands,
expenses (including reasonable compensation, disbursements and expenses of the
Collateral Agent's agents, experts and counsel), losses, obligations, damages,
penalties, actions, judgments, suits, costs, liabilities or disbursements of any
kind and nature whatsoever (the "Indemnified Obligations") which may be imposed
on, incurred by or asserted against the Collateral Agent in its capacity as such
(or such officers, directors, employees or agents) howsoever arising. The
Collateral Agent shall notify the Company promptly of any claim asserted against
the Collateral Agent for which it may seek indemnity; PROVIDED, HOWEVER, that
the Collateral

                                                                              47



Agent's failure to notify the Company of any such claim shall not affect the
Collateral Agent's right to indemnification except to the extent that such
failure to notify is materially prejudicial to the Company's ability to defend
such claim. The Company shall defend any such claim and the Collateral Agent
shall reasonably cooperate at the Company's expense in such defense. The
Collateral Agent shall have separate counsel and the Company shall pay the
reasonable fees and expenses of such counsel; PROVIDED, HOWEVER, that the
Company will not be required to pay such fees and expenses from and after the
date it assumes the Collateral Agent's defense so long as there is no material
conflict of interest between the Company and the Collateral Agent in connection
with such defense. In the event of a material conflict of interest, the
Collateral Agent's right to reimbursement of reasonable fees and expenses of its
separate counsel shall be restored. The Company need not pay for any settlement
made without its prior written consent. The Company need not reimburse any
expense or indemnify against any Indemnified Obligation to the extent incurred
by the Collateral Agent through its gross neg ligence, bad faith or wilful
misconduct. The Company agrees to pay, and to save the Collateral Agent and the
Representatives harmless from, any and all liabilities with respect to, or
resulting from any delay in paying, any and all excise, sales or other taxes
that may be payable or determined to be payable with respect to any of the
Collateral or in connection with any of the transactions contemplated by this
Agreement or any other Security Agreement. The Company agrees to pay, and to
save the Secured Creditors harmless from, any and all liabilities with respect
to, or resulting from any delay in paying, any and all excise, sales or other
similar taxes that may be payable or determined to be payable with respect to
any of the Collateral or in connection with this Agreement or any other Security
Agreement; PROVIDED, HOWEVER, that this sentence shall not obligate the Company
in respect of any income tax or any tax imposed in connection with any transfer
of Securities.

                  (e) All obligations set forth in this Section 7.3 shall
survive the execution, delivery and termination of this Agreement and the other
Security Agreements and the payment or other satisfaction of all the
obligations.

                  SECTION 7.4. COLLATERAL AGENT'S DEALINGS WITH THE COMPANY. The
Collateral Agent may accept deposits from, lend money to, or generally engage in
any kind of banking, trust or other business with the Company or any of its
Affiliates, in each case as if it were not the Collateral Agent hereunder.

                                                                              48



                  SECTION 7.5. RESIGNATION BY OR REMOVAL OF THE COLLATERAL
AGENT. (a) The Collateral Agent may resign from the performance of all its
functions and duties hereunder and under the other Security Agreements at any
time by giving 30 Business Days' prior written notice to the Company and the
Representatives. The Senior Representative may, at any time, remove the
Collateral Agent by giving 30 Business Days' prior written notice to the
Collateral Agent, the Company and each other Representative. The Company shall
have the right to remove the Collateral Agent by written notice to the
Collateral Agent and the Representatives if (i) the Collateral Agent fails to be
an Acceptable Bank, (ii) the Collateral Agent is adjudged bankrupt or insolvent;
(iii) a receiver or other public officer takes charge of the Collateral Agent or
its property, or (iv) the Collateral Agent otherwise becomes incapable of
acting. Such resignation or removal shall take effect upon the appointment of a
successor Collateral Agent pursuant to paragraph (b) or (c) below or as
otherwise provided below.

                  (b) Upon any such notice of resignation or removal, the Senior
Representative shall, with prior notice to the Company, appoint a successor
Collateral Agent hereunder, which shall be an Acceptable Bank. If a successor
Collateral Agent shall not have been so appointed and take office within 30 days
after the retiring Trustee resigns or is removed, the Company shall then appoint
a successor Collateral Agent which shall be an Acceptable Bank and which shall
serve as Collateral Agent hereunder until such time, if any, as the Senior
Representative appoints a successor Collateral Agent as provided above. If no
successor Collateral Agent shall have been so appointed by the Company or the
Senior Representative and accepted appointment in the manner herein provided,
the Collateral Agent or any Secured Creditor may petition any court of competent
jurisdiction for the appointment of a successor Collateral Agent.

                  (c) A successor Collateral Agent shall deliver a written
acceptance of its appointment to the retiring Collateral Agent, to the Company
and each Representative. Immediately thereafter, the retiring Collateral Agent
shall transfer all property held by it as Collateral Agent to the successor
Collateral Agent and shall execute and deliver to the successor Collateral Agent
such documents as are necessary to perfect or maintain the Liens created under
the Security Agreements, including any documents necessary to assign or transfer
all interests of the retiring Collateral Agent in the Collateral to the
successor Collateral Agent, in a form adequate for proper filing or recording in
such offices and such jurisdictions as are necessary to put the successor
Collateral Agent in the same position as the 


<PAGE>

                                                                              49



retiring Collateral Agent with respect to the Collateral. Thereafter, the
resignation or removal of the retiring Collateral Agent shall become effective
and the successor Collateral Agent shall have all the rights, powers and duties
of the Collateral Agent under this Agreement. Any successor Collateral Agent
shall give notice of its succession to each Secured Creditor as of the date of
such succession.

                  (d) If the Collateral Agent consolidates with, merges or
converts into, or transfers all or substantially all its corporate trust
business to, another corporation, the resulting, surviving or transferee
corporation without any further act shall, if such resulting, surviving or
transferee corporation is an Acceptable Bank, be the successor Collateral Agent.
The transferring, merging or converting Collateral Agent shall have all
documents necessary to perfect or maintain the Liens created under the Security
Agreements, including any documents necessary to assign or transfer all
interests of the transferring, merging or converting Collateral Agent in the
Collateral, executed and delivered in a form adequate for proper filing or
recording in such offices and such jurisdictions as are necessary to put the
successor Collateral Agent in the same position as the transferring, merging or
converting Collateral Agent with respect to the Collateral.

                  (e) Any person acting as Collateral Agent shall continue to be
entitled to receive compensation and indemnification as provided in Section 7.3
hereof so long as such Person acts as Collateral Agent hereunder.

                  (f) Nothing herein shall prevent any Representative that is
also an Acceptable Bank from also serving as the Collateral Agent.

                  SECTION 7.6. ADVICES; ACTIONS REQUESTED OF COLLATERAL AGENT.
(a) The Collateral Agent shall forward promptly to each Applicable
Representative a copy of each notice, certificate, instruction or other
communication received by the Collateral Agent from the Company or any other
Representative under this Agreement, any other Security Agreement or any of the
Debt Instruments (except for any which the Company shall be obligated to furnish
directly to such Representative). The Collateral Agent shall also promptly
furnish to each Applicable Representative, upon its written request, such other
information and documents concerning the Collateral and the Collateral Agent's
actions with respect thereto as such Representative may reasonably request.

                                                                              50



                  (b) In connection with any request by the Company to the
Collateral Agent to give its consent pursuant to a provision in any Security
Agreement (other than a consent to amend any Security Agreement), the Collateral
Agent shall be deemed to be authorized by each Representative to give its
consent to the Company on behalf of such Representative at any time after the
Specified Date (as defined below) upon the following conditions:

                  (i) the Company shall provide an Officers' Certificate to the
         Collateral Agent stating that (A) written notice was duly sent, in
         accordance with the applicable Debt Instrument, to all the Secured
         Creditors to the effect that the Company intended to seek the consent
         of the Collateral Agent, (B) that such notice explained in reasonable
         detail the circumstances surrounding the consent sought, (C) that such
         notice explained that the Collateral Agent was permitted pursuant to
         this Agreement to give its consent as requested unless any such
         Representative notifies the Collateral Agent on or prior to the date
         specified (the "Specified Date") in such notice (which shall not be
         less than 30 days after the effectiveness of such notice) that it has
         received written objection from Secured Creditors representing, in the
         aggregate, 25% or more of the aggregate principal amount of the Secured
         Debt for which such Representative is acting (or, with respect to the
         Letter of Credit Reimbursement Agreement, written objection from CSFB),
         and (D) that such notice informed the Secured Creditors that if they
         had any objection to the Collateral Agent's giving such consent, they
         should notify such Representative prior to the Specified Date;

                  (ii) the Company shall have provided to the
         Collateral Agent and the Representatives copies of the
         notice referred to above; and

                  (iii) any such Representative shall not have notified the
         Collateral Agent to withhold its consent as a result of such
         Representative's receipt of objection from Secured Creditors
         representing, in the aggregate, 25% or more of the aggregate principal
         amount of the Secured Debt for which such Representative is acting (or
         with respect to the Letter of Credit Reimbursement Agreement, written
         objection from CSFB).

                  SECTION 7.7. CO-COLLATERAL AGENT; SEPARATE COLLATERAL AGENT.
(a) If at any time or times it shall be necessary or prudent in order to conform
to any law of any jurisdiction in which any of the Collateral shall be 


<PAGE>

                                                                              51



located, or to avoid any violation of law or imposition on the Collateral Agent
of taxes by such jurisdiction not otherwise imposed on the Collateral Agent, or
the Collateral Agent shall be advised by counsel, satisfactory to it, that it is
necessary or prudent in the interest of the Secured Creditors, or the Majority
Secured Creditors or the Trustees shall in writing so request, or the Collateral
Agent shall deem it desirable for its own protection in the performance of its
own duties under any Security Agreement, the Collateral Agent, the Trustees and
the Company as shall be necessary or prudent shall execute and deliver all
instruments and agreements necessary or proper to constitute another bank or
trust company, or one or more persons approved by the Collateral Agent and the
Company, either to act as co-agent or co-agents of all or any of the Collateral
under any of the Security Agreements jointly with the Collateral Agent
originally named herein or therein or any successor Collateral Agent, or to act
as separate agent or agents of any of the Collateral (any of the foregoing, a
"Co-Collateral Agent"). If the Company shall not have joined in the execution of
such instruments and agreements within 10 days after it receives a written
request from the Collateral Agent to do so, the Collateral Agent may act under
the foregoing provisions of this Section 7.7(a) without the concurrence of the
Company and execute and deliver such instruments and agreements on behalf of the
Company. The Company hereby appoints the Collateral Agent as its agent and
attorney to act for it under the foregoing provisions of this Section 7.7(a) in
either of such contingencies.

                  (b) Every Co-Collateral Agent, other than any successor
Collateral Agent appointed pursuant to Section 7.5, shall, to the extent
permitted by law, be appointed and act and be such, subject to the following
provisions and conditions:

                  (i) all rights, powers, duties and obligations conferred upon
         the Collateral Agent in respect of the custody, control and management
         of moneys, papers or securities shall be exercised solely by the
         Collateral Agent or any agent appointed by the Collateral Agent;

                  (ii) all rights, powers, duties and obligations conferred or
         imposed upon the Collateral Agent under the relevant Security
         Agreements shall be conferred or imposed and exercised or performed by
         the Collateral Agent and such separate agent or separate agents or co-
         agent or co-agents, jointly, as shall be provided in the instrument
         appointing such separate agent or separate agents or co-agent or
         co-agents, except to the extent that under any law of any jurisdiction
         in which 


<PAGE>

                                                                              52



         any particular act or acts are to be performed the Collateral Agent
         shall be incompetent or unqualified to perform such act or acts, or
         unless the performance of such act or acts would result in the
         imposition of any tax on the Collateral Agent which would not be
         imposed absent such joint act or acts, in which event such rights,
         powers, duties and obligations shall be exercised and performed by such
         separate agent or separate agents or co-agent or co-agents;

                  (iii) no power given by any Security Agreement to, or which it
         is provided herein or therein may be exercised by, any such co-agent or
         co-agents or separate agent or separate agents, shall be exercised
         hereunder or thereunder by such co-agent or co-agents or separate agent
         or separate agents except jointly with, or with the consent in writing
         of, the Collateral Agent, anything contained in any Security Agreement
         to the contrary notwithstanding;

                  (iv) no agent hereunder shall be personally liable
         by reason of any act or omission of any other agent
         hereunder; and

                  (v) the Company and the Collateral Agent, at any time by an
         instrument in writing executed by them jointly, may accept the
         resignation of or remove any such separate agent or co-agent and, in
         that case by an instrument in writing executed by them jointly, may
         appoint a successor to such separate agent or co-agent, as the case may
         be, anything contained herein to the contrary notwithstanding. If the
         Company shall not have joined in the execution of any such instrument
         within 10 days after it receives a written request from the Collateral
         Agent to do so, the Collateral Agent shall have the power to accept the
         resignation of or remove any such separate agent or co-agent and to
         appoint a successor without the concurrence of the Company, the Company
         hereby appointing the Collateral Agent its agent and attorney to act
         for it in such connection in such contingency. If the Collateral Agent
         shall have appointed a separate agent or separate agents or co-agent or
         co-agents as above provided, the Collateral Agent may at any time, by
         an instrument in writing, accept the resignation of or remove any such
         separate agent or co-agent and the successor to any such separate agent
         or co-agent shall be appointed by the Company and the Collateral Agent,
         or by the Collateral Agent alone pursuant to this Section 7.7(b).

                                  ARTICLE VIII

                              EXERCISE OF REMEDIES

                  SECTION 8.1. EXERCISE OF REMEDIES UNDER SECURITY AGREEMENTS.
(a) If any Representative has notice of a Potential Payment Event of Default or
Event of Default, such Representative shall promptly give written notice to the
other Representatives and to the Collateral Agent. As promptly as practicable,
after receipt of such notice of Potential Payment Event of Default or Event of
Default, the Senior Representative shall give written instructions to the
Collateral Agent as to the actions, if any, that are permitted by the Debt
Instruments and the Security Agreements to be taken by the Collateral Agent.
Upon receipt by the Collateral Agent of notice of a Potential Payment Event of
Default or Event of Default and written instructions from the Senior
Representative as to such actions, if any, to be taken by the Collateral Agent,
the Collateral Agent shall, within four Business Days after receipt of such
instructions, commence the taking of such actions, as specifically instructed in
writing by the Senior Representative or, in the event the Senior Representative
fails to deliver such instructions, by the Majority Secured Creditors. If any
Potential Payment Event of Default or Event of Default which was the basis for
the giving of a notice to the Collateral Agent shall be cured or waived in
accordance with the terms of the applicable Debt Instrument, any direction to
the Collateral Agent to take any action in connection with such notice shall be
deemed rescinded with respect to any action to be taken by the Collateral Agent
upon notification by the Representative to the Collateral Agent under the
applicable Debt Instrument of such cure or waiver, as applicable.

                  In no event may any Representative direct the exercise by the
Collateral Agent, nor shall the Collateral Agent exercise, any remedy which
would result in the discharge of any of the Obligations by reason of any anti
deficiency statute or law relating to sales of Collateral other than through
judicial proceedings.

                  (b) Prior to the occurrence of a Potential Payment Event of
Default or an Event of Default and receipt of a notice to such effect by the
Collateral Agent pursuant to Section 8.1(a) hereof, in the event (i) the
Collateral Agent shall receive any written request from the Company under any
Security Agreement for consent or approval with respect to any matter or thing
relating to any Collateral or the Company's obligations with respect thereto or
(ii) there shall be due to or from the Collateral Agent under the 


<PAGE>

                                                                              54



provisions of any Security Agreement any material performance or the delivery of
any material instrument or (iii) a Responsible Officer of the Collateral Agent
shall have actual knowledge of any nonperformance by the Company of any covenant
or any breach of any representation or warranty set forth in any Security
Agreement, then, in each such event, the Collateral Agent shall advise the
Representatives in writing of the matter or thing as to which consent has been
requested or the performance or instrument required to be delivered or the
nonperformance or breach of which the Collateral Agent has become aware;
PROVIDED, HOWEVER, that, subject to Section 7.6(b), the Senior Representative
shall have the exclusive authority to direct (subject to the right of the
Majority Secured Creditors to otherwise direct in the absence of such direction)
the Collateral Agent's response to any of the circumstances contemplated in
clauses (i), (ii) and (iii) above.

                  (c) All the Secured Creditors shall be bound by any
instruction or direction given by the Senior Representative or, in the absence
of such instructions or direction, by the Majority Secured Creditors pursuant to
this Section 8.1 or deemed given pursuant to Section 7.6(b). The Representatives
shall take such actions as are necessary to enable the Collateral Agent to
comply with the provisions of the Security Agreements. Anything in this
Agreement to the contrary notwithstanding, under no circumstances shall the
Senior Representative have, or be deemed to have, any fiduciary or other duty to
any other Representative or any Secured Creditor with respect to actions it is
permitted to take hereunder, and the Senior Representative (if CSFB or the First
Priority Trustee) shall at all times be entitled to take, and fully protected in
taking, such actions in accordance with instructions received under and pursuant
to the Letter of Credit Reimbursement Agreement or the First Priority Indenture,
as the case may be.

                  (d) The Collateral Agent may rely on any document reasonably
believed by it to be genuine and to have been signed or presented by the proper
person. The Collateral Agent need not investigate any fact or matter stated in
any such document. Before the Collateral Agent acts or refrains from acting it
may consult with counsel and may require an Officers' Certificate, an Opinion of
Counsel (to be delivered at the expense of the Company or any other source
deemed acceptable to the Collateral Agent, at its sole discretion) or both. The
Collateral Agent shall not be liable for any action it takes, omits to take or
suffers in good faith in reliance on any such certificate or opinion or in
accordance with a direction or instruction received by it from any
Representative hereunder.


<PAGE>

                                                                              55



                  The Collateral Agent may act through its attorneys and agents
and shall not be responsible for the misconduct of any agent appointed with due
care. The Collateral Agent shall not be liable for any action it takes or omits
to take in the good faith belief that such act or omission was authorized or
within its rights or powers conferred upon it hereunder or under the other
Security Agreements. The Collateral Agent shall not be bound to make any
investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent,
order, bond, debenture, note, other evidence of indebtedness or other paper or
document, but the Collateral Agent, upon specific written instructions from any
Representative, may make such further inquiry or investigation into such facts
or matters in accordance with such instructions.

                  The Collateral Agent shall be under no obligation to exercise
any of the rights or powers vested in it by any Security Agreement at the
request, order or direction of any Representative or pursuant to Section 7.6(b)
hereof, unless the Collateral Agent shall have been provided by any
Representative, by any other Secured Creditor or by the Company, as may be
agreed at the time, security or indemnity satisfactory to the Collateral Agent
in its sole discretion and from any source acceptable to the Collateral Agent
against the costs, expenses and liabilities which might be incurred by it in
compliance with such request, order or direction. Upon receipt of such security
or indemnity, however, the Collateral Agent shall act upon the specific
instructions of the Senior Representative. Notwithstanding the foregoing, the
Collateral Agent shall not take such action if such action would violate the
terms of the Security Agreements.

                  The Collateral Agent is acting hereunder not in its individual
capacity but solely as agent for the Representatives, and the Collateral Agent
shall not be responsible for and makes no representation as to the validity or
adequacy of the Debt Instruments, the Letter of Credit Reimbursement Agreement,
the First Priority Notes, the Second Priority Notes, this Agreement or any other
Security Agreement, shall not be responsible for the use by the Grantors of any
funds payable to or retainable by the Grantors hereunder and shall not be
responsible for the accuracy of any statements, certifications or other
information provided to it by the Grantors or any other person pursuant hereto.
The Collateral Agent shall not be liable for any error of judgment made in good
faith by a responsible officer of the Collateral Agent unless it is proved that
the Collateral Agent was negligent in ascertaining the pertinent facts. Any
reference herein to 


<PAGE>

                                                                              56



knowledge of the Collateral Agent with respect to any circumstance, fact or
event shall mean the actual knowledge of a responsible officer in the corporate
trust department of the Collateral Agent. Except during the continuance of an
Event of Default, the Collateral Agent undertakes to perform such duties, and
only such duties, as are specifically set forth herein, and no implied covenants
or obligations shall be read into this Agreement against the Collateral Agent.
If an Event of Default has occurred and is continuing, the Collateral Agent
shall exercise 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 person would exercise
or use under the circumstances in the conduct of such Person's own affairs.

                  (e) Each of the Grantors hereby irrevocably constitutes and
appoints the Collateral Agent and any officer or agent thereof, with full power
of substitution, as its respective true and lawful attorney-in-fact with full
power and authority in the name of such Grantor or in its own name, as the case
may be, from time to time in the Collateral Agent's discretion, so long as any
Event of Default is in effect, to take any and all appropriate action directed
by the Senior Representative or the Majority Secured Creditors and to execute
any and all documents and instruments which may be necessary or desirable to
carry out the terms hereof and accomplish the purposes hereof and, without
limiting the generality of the foregoing or any of the rights conferred on the
Collateral Agent, whether in its own right or as assignee of the Grantors;
pursuant to the other Security Agreements, each of the Grantors hereby gives the
Collateral Agent the power and right on its behalf, without notice to or further
assent by any other Grantor, so long as any Event of Default is in effect, to do
the following (to the extent the Collateral Agent is directed to do so by the
Senior Representative or the Majority Secured Creditors):

                  (i) to ask for, demand, sue for, collect, receive
         and give acquittance for any and all moneys due or to
         become due upon, or in connection with, the Collateral;

                  (ii) to receive, take, endorse, assign and deliver any and all
         checks, notes, drafts, acceptances, documents and other negotiable and
         nonnegotiable instruments taken or received by the Collateral Agent as,
         or in connection with, the Collateral;

                  (iii) to commence, prosecute, defend, settle, compromise,
         compound or adjust any claim, suit, action or proceeding with respect
         to, or in connection with, the Collateral;


<PAGE>

                                                                              57



                  (iv) to sell, transfer, assign or otherwise deal in or with
         the Collateral or any part thereof as fully and effectively as if the
         Collateral Agent were the absolute owner thereof;

                  (v) to do, at its option and at the expense and for the
         account of the Grantors, at any time or from time to time, all acts and
         things which the Collateral Agent shall deem necessary or advisable to
         protect or preserve the Collateral and to realize upon the Collateral;

                  (vi) to extend the time of payment of any or all of
         the Collateral and to make any allowance and other
         adjustments with reference thereto; and

                  (vii) to exercise any of the remedies set forth in
         the Security Agreements;

PROVIDED that, except as provided in Section 6.9, the Collateral Agent shall
give each of the Grantors not less than 30 days' prior written notice of the
time and place of any sale or other intended disposition of any Collateral. Each
of the Grantors agrees that such notice constitutes "reasonable notification"
within the meaning of Section 9-504(3) of the Uniform Commercial Code.

Trustee and the Second Priority Trustee and each holder of any First Priority
Notes or Second Priority Notes (i) agree that the lien and security interests of

the time, manner or order of perfection, grant or creation of any security
interests or Liens in the Collateral on behalf of any Secured Creditor or the
incurrence of any such Notes or Indebtedness and notwithstanding any provision
of the Uniform Commercial Code or any applicable law of any jurisdiction or any
other circumstance, be prior to the lien and security interests of the First
Priority Trustee and the Second Priority Trustee and the holders of the First
Priority Notes and the Second Priority Notes in the Collateral, including their
interests in any such payments, and any Lien of the First Priority Trustee or
the Second Priority Trustee in the Collateral now or hereafter held and

shall be junior and subordinate to all Liens in the Collateral held by CSFB (and
from time to time agree to execute and deliver any instruments or agreements as

contest or support any other Person in contesting, in any proceeding (including
without limitation any insolvency or liquidation proceeding), the priority,

Trustee or the Second Priority Trustee is the Senior Representative, shall

in at foreclosure or otherwise), take possession of, liquidate or otherwise
exercise any right or remedy in respect of the Collateral or proceed against any
of the Collateral.

                  (b) The Second Priority Trustee and each holder of any Second

each holder of any First Priority Notes in the Collateral, including their
interests in any payments to be made from the proceeds of any sale or other
disposition thereof, shall, irrespective of the time of perfection or creation
of any security interests or Liens in the Collateral on behalf of any Secured
Creditor or the incurrence of any such Notes or Indebtedness, be prior to the
interests of the Second Priority Trustee and the holders of the Second Priority
Notes in the Collateral, including their interests in any such payments, to the
extent and in the manner provided below (and from time to time shall execute and
deliver any instruments or agreements as may be reasonably necessary or
desirable to confirm the same) and (ii) unless the Second Priority Trustee is
the Senior Representative, shall refrain from taking any action to foreclose
upon, acquire title to (by bidding in at foreclosure or otherwise), take
possession of, liquidate or otherwise proceed against any of the Collateral.

Any party hereto may by notice to each other party designate such additional or
different addresses as shall be furnished in writing by such party. Any notice
or communication to any party hereto shall be deemed to have been given or made
as of the date so delivered, if personally delivered; when answered back, if
telexed; when receipt is acknowledged, if telecopied; and five calendar days
after mailing if sent by registered or certified mail (except that a notice of
change of address shall not be deemed to have been given until actually received
by the addressee). A copy of any notice given under this Agreement to any party
shall also be given to each other party hereto.

                  SECTION 10.3. BINDING AGREEMENT; ASSIGNMENT; OBLIGATIONS
SEVERAL. This Agreement shall be binding upon the Grantors and each of their
successors and assigns, and inure, together with the rights and remedies of the
Collateral Agent hereunder, to the benefit of the Collateral Agent, each
Representative and each Secured Creditor and each of their respective
successors, transferees and assigns; no other Persons (including any other
creditor of the Company) shall have any interest herein or any right or benefit
with respect hereto. Without limiting the generality of the foregoing clause,
the Collateral Agent and any Representative and Secured Creditor may assign or
otherwise transfer any indebtedness held by it secured by this Agreement to any
other person, and such other person shall thereupon become vested with all the
benefits in respect thereof granted to such party herein or otherwise. Neither
this Agreement nor any interest herein or in the Collateral, or any part
thereof, except as otherwise permitted herein or in the Debt Instruments or the
Security Agreements, may be assigned by any Grantor; PROVIDED, HOWEVER, that
this Agreement may be assigned by a Grantor to any person that shall become a
successor obligor of such Grantor under the Debt Instruments in compliance with
Article 5 of the Indentures and Section 11 of the Letter of Credit Reimbursement
Agreement if such person executes and delivers an amendment hereto whereby it
expressly assumes all obligations of the Company hereunder as if it were an
original party hereto. This Agreement shall be deemed to be automatically
assigned by the Collateral Agent to any person who succeeds to the Collateral
Agent in accordance with Section 9 hereof, and such assignee shall have all
rights and powers of, and act as, the Collateral Agent hereunder, and this
Agreement shall be deemed to be automatically assigned by any of the
Representatives to those persons who succeed to any of them in accordance with
the provisions of the applicable Debt Instrument. Except as otherwise expressly
provided herein, the obligations of each of the parties under this Agreement are
several and not joint, it being expressly agreed that no Representative shall be


<PAGE>

                                                                              61



liable for the failure of any other Representative to perform its duties or
obligations hereunder.

                  SECTION 10.4. GOVERNING LAW. This Agreement shall be governed
by and construed in accordance with the laws of the State of New York, without
regard to conflicts of law principles, except to the extent that the laws of any
other jurisdiction may be mandatorily applicable.

                  SECTION 10.5. EFFECTIVENESS; TERMINATION. This Agreement shall
become effective on the date on which all of the parties hereto shall have
signed a copy hereof (whether the same or different copies) and shall have
delivered the same to the Collateral Agent. This Agreement shall remain
effective until, and terminate when, all Obligations are indefeasibly satisfied
and the Collateral Agent receives written notification from each Representative
that the Obligations owed to such Representative have been so satisfied in full.
Upon termination of this Agreement, the Collateral Agent shall reassign and
redeliver to the Grantors any Collateral which has not been sold, disposed of,
retained or applied by the Collateral Agent in accordance with the terms hereof
or of any other Security Agreement. Such reassignment and redelivery shall be
without warranty by or recourse to the Collateral Agent, and shall be at the
expense of the Company. Thereafter, no Security Agreement shall constitute a
Lien upon or grant any security interest in any of the Collateral and the
Collateral Agent shall, at the Company's expense and pursuant to the Company's
written instructions, deliver to the Company written acknowledgment thereof and
of cancelation of this Agreement and all other Security Agreements in a form as
reasonably requested by the Company and adequate for proper filing or recording
in such offices and such jurisdictions as the Company reasonably deems necessary
to release the Liens created under the Security Agreements. This Agreement shall
continue to be effective or be reinstated, as the case may be, if at any time
any payment of any of the Obligations is rescinded or must be otherwise returned
upon the insolvency, bankruptcy or reorganization of the Company, Holdings, or
any Owner or otherwise, all as though such payment had not been made and, if
applicable, this Agreement had not been terminated.

                  SECTION 10.6. AMENDMENT. This Agreement may be amended,
changed, waived, discharged or terminated with the written consent of the
Company and the Applicable Representatives (who shall only grant such consent in
accordance with the relevant provisions of the appropriate Debt Instrument). If
in the opinion of the Collateral Agent any document required to be executed
pursuant to the terms of this Section 10.6 affects any interest or right or duty


<PAGE>

                                                                              62



or immunity or indemnity in favor of the Collateral Agent under this Agreement
or any other Security Agreement, the Collateral Agent may in its discretion
decline to execute such document.

                  SECTION 10.7. DISCRETION OF THE COLLATERAL AGENT. Any right,
power or authority granted hereunder or under any other Security Agreement to
the Collateral Agent to be exercised by the Collateral Agent in its discretion,
shall be deemed to be duly exercised in accordance with this Agreement upon
receipt by the Collateral Agent of written instructions signed by the Senior
Representative as to such right, power or authority to be exercised and the
exercise by the Collateral Agent in accordance therewith. The Collateral Agent
shall not be responsible for exercising any such right, power or authority
absent receipt of such instructions unless such failure to so exercise any such
right, power or authority would constitute negligence, bad faith or wilful
misconduct of the Collateral Agent or result in a violation of the specific
requirements of any Security Agreement. Notwithstanding the foregoing, upon the
occurrence of an Event of Default, the Collateral Agent's failure to exercise
any such right, power or authority absent receipt of such instructions shall not
constitute negligence, bad faith or wilful misconduct of the Collateral Agent.

                  SECTION 10.8. INCONSISTENT PROVISIONS. If any provision of
this Agreement shall be inconsistent with, or contrary to, any provision in any
other Security Agreement, such provision of this Agreement shall be controlling,
and shall supersede such inconsistent provision to the extent necessary to give
full effect to all provisions contained in this Agreement. If any provision of
this Agreement shall be inconsistent with, or contrary to, any provision of any
of the Debt Instruments, upon receipt of written notification from the
Applicable Representative, such provision of such Debt Instrument shall be
controlling, and shall supersede such inconsistent provisions hereof to the
extent necessary to give full effect to such provision of such Debt Instrument.

                  SECTION 10.9. SEVERABILITY. In the event that any provision
contained in this Agreement shall for any reason be held to be illegal or
invalid under the laws of any jurisdiction, such illegality or invalidity shall
in no way impair the effectiveness of any other provision hereof or of such
provision under the laws of any other jurisdiction; PROVIDED, HOWEVER, that in
the construction and enforcement of such provisions under the laws of the
jurisdiction in which such holding of illegality or invalidity exists, and to
the extent only of such illegality 


<PAGE>

                                                                              63



or invalidity, this Agreement shall be construed and enforced as though such
illegal or invalid provision had not been contained herein.

                  SECTION 10.10.  HEADINGS.  Section headings used
herein are inserted for convenience only and shall not in
any way affect the meaning or construction of any provision
of this Agreement.

                  SECTION 10.11. COUNTERPARTS. This Agreement may be executed in
any number of counterparts, each of which when so executed and delivered shall
be an original, and all of which shall together constitute one and the same
instrument. A complete set of counterparts shall be lodged with the Collateral
Agent and with each Representative.

                  SECTION 10.12. AGENT FOR SERVICE; SUBMISSION TO JURISDICTION;
WAIVER OF IMMUNITIES. By the execution and delivery of this Agreement, the
Company, Holdings and each of the Owners (i) acknowledges that it has, by
separate written instrument, irrevocably designated and appointed Cambridge
Partners, L.L.C. ("CPLLC"), (and any successor entity), as its authorized agent
upon which process may be served in any suit or proceeding arising out of or
relating to this Agreement that may be instituted in any federal or state court
in the State of New York, Borough of Manhattan or brought by the Collateral
Agent (whether in its individual capacity or in its capacity as Collateral Agent
hereunder), the Trustees (whether in their individual capacities or in their
capacities as Trustees under the Indentures) or CSFB (whether in its individual
capacity or in its capacity as administrating bank and funding bank under the
Letter of Credit Reimbursement Agreement) and acknowledges that CPLLC has
accepted such designation, (ii) submits to the jurisdiction of any such court in
any such suit or proceeding, and (iii) agrees that service of process upon CPLLC
and written notice of said service to the Company, Holdings or the applicable
Owner, shall be deemed in every respect effective service of process upon the
Company, Holdings or such Owner, as the case may be, in any such suit or
proceeding. The Company, Holdings and each of the Owners further agree to take
any and all action, including the execution and filing of any and all such
documents and instruments, as may be necessary to continue such designation and
appointment of CPLLC in full force and effect so long as this Agreement shall be
in full force and effect.

                  The Company, Holdings and each of the Owners hereby
irrevocably and unconditionally waive, to the fullest extent they may legally
effectively do so, any objection which they may now or hereafter have to the
laying of venue

                                                                              64



of any suit, action or proceeding arising out of or relating to this Agreement
or the other Security Agreements in any federal or state court in the State of
New York, Borough of Manhattan. The Company, Holdings and each of the Owners
hereto hereby irrevocably waives, to the fullest extent permitted by law, the
defense of an inconvenient forum to the maintenance of such action or proceeding
in any such court.

                  To the extent either the Company, Holdings or any of the
Owners has or hereafter may acquire any immunity from jurisdiction of any court
or from any legal process (whether through service of notice, attachment prior
to judgment, attachment in aid of execution, execution or otherwise) with
respect to itself or its property, it hereby irrevocably waives such immunity in
this Agreement and the other Security Agreements, to the extent permitted by
law.

                  IN WITNESS WHEREOF, the Collateral Agent, the First Priority
Trustee for the benefit of the holders of the First Priority Notes, the Second
Priority Trustee for the benefit of the holders of the Second Priority Notes,
CSFB for the benefit of the Funding Bank and the Participating Banks party to
the Letter of Credit Reimbursement Agreement, the Company, Holdings and the
Owners have caused this Agreement to be executed and delivered by their
respective

                          [Form of Opinion of Counsel]

                  This opinion is being delivered pursuant to Section
3.5(a)(vii) of the Collateral Agency and Intercreditor Agreement dated as of
August 1, 1997 (the "Intercreditor Agreement"), between the Company, Holdings,
the Owners, the Collateral Agent, the First Priority Trustee and the Second
Priority Trustee. Capitalized terms used but not defined herein have the
meanings given such terms in the Intercreditor Agreement or the Indentures. We
are of opinion that:

                  1. All conditions precedent set forth in Section 3.5(a) of the
         Intercreditor Agreement to the disbursement of certain funds from the
         Pre-Funding Account on the date hereof have been satisfied or will be
         satisfied immediately after such disbursement of funds.

                  2. Each of the Security Agreements relating to the Vessel
         ____________ to which the Company or Navigator Gas (IOM I-[ ]) Limited
         (the "Owner") is a party has been duly authorized, executed and
         delivered by the Company or the Owners, as the case may be, is a valid
         and binding agreement of the Company, and the Owners party thereto,
         enforceable against the Company and the Owners in accordance with its
         terms under the laws of the Republic of Liberia, in the case of the
         Mortgage, and the laws of the State of New York, in the case of the
         Assignments of Earnings and Insurances (the "Assignment"), and the laws
         of the Isle of Man, in the case of the Issue of One Debenture (the
         "Debenture"), subject to bankruptcy, insolvency fraudulent transfer,
         reorganization, moratorium or similar laws affecting creditors' rights
         and to general equity principles.

                  3. No authorization, consent, license, permission, permit or
         approval (including exchange control approval) of or action by, and no
         notice to or filing with, any governmental authority or regulatory body
         of the Republic of Liberia or, in the case of the Assignment, of the
         State of New York or, in the case of the Debenture, the Isle of Man is
         required for the execution, delivery and performance of any of the
         Security Agreements by the respective parties thereto and no such
         authorization, consent, license, permission, permit, approval, action,
         notice or filing is required for the exercise by the Collateral Agent
         of the rights and remedies granted to it under any of the Security
         Agreements, except for the filing and registration of the Mortgage in
         the Office of the Deputy Commissioner of Maritime Affairs of the
         Republic


                                       D-1
<PAGE>

         of Liberia and the Debenture in the applicable
         government office in the Isle of Man.

                  4. The security interests created by each Security Agreement
         (other than the Mortgage) do not require any action to be taken under
         or pursuant to the laws of the Republic of Liberia or, in the case of
         the Assignment, of the State of New York, or, in the case of the
         Debenture, the Isle of Man in order to create or perfect such security
         interests or to permit the Collateral Agent to enforce its rights under
         the Security Agreement creating the same, other than (i) due and timely
         notice of the Assignment to charterers and third parties and (ii) due
         and timely notice of the Assignment to underwriters and third parties,
         as well as the consent of such underwriters or such third parties where
         the terms of insurance policies, other insurance documents or
         provisions of applicable law so require.

                  5. Based upon the Certificate of Ownership and Encumbrance
         issued by the Bureau of Maritime Affairs of the Republic of Liberia,
         the Vessels are registered under the laws of the Republic of Liberia,
         solely owned by the Owner, and free of all mortgages, liens and
         encumbrances of record other than the Mortgage in favor of the
         Collateral Agent.

                  6. Based upon the records of the Deputy Commission of Maritime
         Affairs of the Republic of Liberia maintained in New York, New York,
         the Mortgage on the Vessel ________ has been duly recorded in the
         Office of Deputy Commissioner of Maritime Affairs of the Republic of
         Liberia in New York on _________ in Book PM __ at Page ___ and such

(whether or not having the force of law) of any such Governmental Authority,
central bank or comparable agency shall impose, modify or deem applicable any
reserve, special deposit or similar requirement (including, without limitation,
any such requirement imposed by the Board) against letters of credit issued by
or participated in or assets of, or deposits with or for the account of such
Bank or Participant or shall impose on such Bank or Participant any other
condition regarding this Agreement, the Letter of Credit or any Bank's
participation therein and the result of the foregoing shall be to increase the
cost to such Bank or Participant of issuing, maintaining or participating, as
the case may be, in the Letter of Credit or any drawing thereunder, then, within
15 days after demand by such Bank or Participant, the Issuer agrees to pay to
such Bank or Participant all additional amounts that are necessary to compensate
such Bank or Participant for such increased cost.

                        (b)  If any Bank or Participant shall have
determined that the adoption after the date hereof of any Applicable Law or
guideline regarding capital adequacy, or any change in any of the foregoing or
in the interpretation or administration of any of the foregoing by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by such Bank or
Participant (or any lending office thereof) or such Bank's or Participant's
holding company with any request or directive regarding capital adequacy
(whether or not having the force of law) of any such Governmental Authority,
central bank or comparable agency, has or would have the effect of reducing the
rate of return on such Bank's or Participant's capital or on the capital of such
Bank's or Participant's holding company, if any, as a consequence of this
Agreement or under or in connection with the Letter of Credit to a level below
that which such Bank or Participant or such Bank's or Participant's holding
company could have achieved but for such adoption, change or compliance (taking
into consideration such Bank's or Participant's policies and the policies of
such Bank's or Participant's holding company with respect to capital adequacy)
by an amount deemed by such Bank or Participant to be material, then, within 15
days after demand by such Bank or Participant, the Issuer shall pay to such Bank
or Participant such additional amount or amounts as will compensate such Bank or
Participant or such Bank's or Participant's holding company for any such
reduction suffered.

                        (c) The Issuer agrees that all payments made by the
Issuer hereunder shall be made free and clear of, and


<PAGE>

                                                                              11


without reduction for or on account of, any stamp or other taxes, levies,
imposts, duties, charges, fees, deductions, withholdings, restrictions or
conditions of any nature whatsoever hereafter imposed, levied, collected,
withheld or assessed by any country (or by any political subdivision or taxing
authority thereof or therein), except for franchise taxes and taxes on the
overall net income of a Bank (such nonexcluded taxes being called "Tax" or
"Taxes"). If any Taxes are required to be withheld from any amounts payable by
the Issuer hereunder, the Issuer agrees that the amounts so payable shall be
increased to the extent necessary to yield to the Banks (after payment of all
Taxes) interest or any such other amounts payable hereunder at the rates or in
the amounts specified in this Agreement; PROVIDED that the Issuer shall not be
obligated to pay such amounts for the benefit of any Bank with respect to any
period in which such Bank has failed (x) to file any form or certificate that it
was entitled to file which would have exempted such Bank from such Taxes or (y)
to take other action which would entitle such Bank to an exemption from such
Taxes, if such action would not, in the reasonable judgment of such Bank, be
otherwise disadvantageous to it. Whenever any Tax is paid by the Issuer with
respect to payments made to or for the account of any Bank, as promptly as
possible thereafter, the Issuer shall send the Administrating Bank and the
applicable Bank a receipt or other evidence of payment thereof.

                        (d)  A certificate as to the nature of the
occurrence giving rise to, and the calculation of, compensation to the Funding
Bank, a Participating Bank or a Participant pursuant to paragraphs (a), (b) and
(c) of this Section 4 shall be submitted by the Funding Bank, such Participating
Bank or such Participant to the Administrating Bank. Such certificate shall be
submitted by the Administrating Bank to the Issuer and shall be conclusive
evidence (absent demonstrable error) as to the amount thereof. Each such
certificate shall provide the identity of the Funding Bank, such Participating
Bank or such Participant.

                        (e) In the event any Participating Bank gives a notice
with respect to it or any of its Participants pursuant to Section 4(d) hereof,
the Issuer may require, at its expense, such Bank to assign all its
Participation Percentage of the Letter of Credit and all its rights and
obligations hereunder to a financial institution specified by the Issuer (a
"Substitute Bank"); PROVIDED that (i) such assignment shall not conflict with or
violate any law, rule or regulation or order of any court or other governmental


<PAGE>

                                                                              12

agency or instrumentality, (ii) the Issuer shall have received the written
consent of the Funding Bank and the Administrating Bank (which shall not
unreasonably be withheld), to such assignment and (iii) the Issuer shall have
paid to such assignor Bank all moneys accrued and owing hereunder to it. The
Substitute Bank shall execute an Assignment and Acceptance and such additional
amendments, agreements, instruments and documents as may be reasonably requested
by the Administrating Bank.

                        (f) In the event the Funding Bank gives a notice with
respect to itself pursuant to Section 4(d) hereof, the Issuer may replace such
Funding Bank with a financial institution specified by the Issuer (a "Substitute
Funding Bank"); PROVIDED that (i) such replacement shall not conflict with or
violate any law, rule or regulation or order of any court or other government
agency or instrumentality, (ii) the Issuer shall have received the written
consent of the Collateral Agent to such substitution, and the Issuer shall have
taken all other actions required under the Transaction Documents to effect such
substitution and (iii) the Issuer shall have paid to the Funding Bank all moneys
accrued and owing hereunder to it. The Substitute Funding Bank shall execute an
Assignment and Acceptance and such additional amendments, agreements,
instruments and documents as may be reasonably requested by the Administrating
Bank.

                        SECTION 5.  PARTICIPATIONS.  (a)  By the issuance
of the Letter of Credit and without any further action on the part of the
Funding Bank or any Participating Bank in respect thereof, the Funding Bank
shall be deemed to have granted to each Participating Bank, and each
Participating Bank shall be deemed to have acquired from the Funding Bank, a
participation in the Letter of Credit equal to such Participating Bank's
Participation Percentage of the Maximum Credit Amount of the Letter of Credit,
effective upon the issuance of the Letter of Credit. In consideration and in
furtherance of the foregoing, each Participating Bank hereby absolutely and
unconditionally agrees to pay to the Funding Bank, in accordance with this
Section 5, such Participating Bank's Participation Percentage of each payment
made by the Funding Bank of a draft under the Letter of Credit. Upon payment of
a draft under a Letter of Credit, the Funding Bank shall promptly give
telephonic notice (to be followed by delivery by telecopy of a Notice of
Drawing) to each Participating Bank of the date and amount of such payment. If
such Notice of Drawing is received by a Participating Bank after 12:30 p.m.
(London time) such notice shall be deemed to have been received on the next
Business Day. With

                                                                              13


respect to each Participating Bank, promptly upon receipt of such Notice of
Drawing but in any event no later than 3:00 p.m. (London time) on the date on
which such Participating Bank shall have received or shall be deemed to have
received such Notice of Drawing from the Funding Bank, such Participating Bank
shall pay to the Funding Bank an amount equal to the product of (A) such
Participating Bank's Participation Percentage and (B) the amount of the payment
made by the Funding Bank on such draft; PROVIDED, HOWEVER, that, with respect to
the payment of any draw on the Letter of Credit, the Funding Bank shall not
require such Participating Bank to pay (exclusive of interest) an amount greater
than the product of (x) such Participating Bank's Participation Percentage and
(y) the lesser of (m) the Maximum Available Credit Amount of the Letter of
Credit immediately prior to adjustment for payment by the Funding Bank of such
draw and (n) the Maximum Drawing Amount of the Letter of Credit immediately
prior to adjustment of the Maximum Drawing Amount of the Letter of Credit for
payment by the Funding Bank of such draw. If payment of the amount due pursuant
to the preceding sentence from a Participating Bank is received by the Funding
Bank after 3:00 p.m. (London time) on the date it is due, such Participating
Bank agrees to pay to the Funding Bank along with its payment of the amount due
pursuant to the preceding sentence, interest on such amount at a rate per annum
equal to the LIBO Rate applicable to such drawing under the Letter of Credit.

                        (b) Each Participating Bank acknowledges and agrees that
its obligation to make the payments specified in Section 5(a) hereof and the
right of the Funding Bank to receive the same, in the manner specified therein,
are absolute, unconditional and irrevocable and shall be performed strictly in
accordance with the terms of this Agreement under any and all circumstances
whatsoever, including, without limitation (i) the occurrence and continuance of
any event of default under any of the Transaction Documents or any terms or
provision therein, (ii) any Reimbursement Default hereunder, (iii) any breach or
default by the Issuer, the Administrating Bank or any Participating Bank
hereunder, (iv) any lack of validity or enforceability of the Letter of Credit,
this Agreement or any of the Transaction Documents or any term or provision
therein, (v) any amendment or waiver of or any consent to departure from the
Letter of Credit, this Agreement or any of the Transaction Documents; and (vi)
the existence of any claim, setoff, defense or other right which the
Participating Banks may have at any time against the Issuer, Holdings, the
Owners, the Collateral Agent (or any persons for whom any of the foregoing may
be acting), the Funding

                                                                              14


Bank, the Administrating Bank, any other Participating Bank, or any other
Person, whether in connection with this Agreement, the Transaction Documents or
any other documents contemplated hereby or thereby or any unrelated
transactions; (vii) any draft or other document presented under the Letter of
Credit proving to be forged, fraudulent, invalid, or insufficient in any respect
or any statement therein being untrue or inaccurate in any respect whatever;
(viii) payment by the Funding Bank under the Letter of Credit against
presentation of a draft or a certificate which does not comply with the terms of
the Letter of Credit; or (ix) any other circumstances or happening whatsoever,
whether or not similar to any of the foregoing, that might, but for the
provisions of this Section, constitute a legal or equitable discharge of, or
provide a right of setoff against, such Participating Bank's obligations
hereunder. Neither the Administrating Bank nor the Funding Bank, nor any of
their respective directors, officers, employees, agents or advisors, shall have
any liability or responsibility by reason of or in connection with the issuance
or transfer of the Letter of Credit or any payment or failure to make any
payment thereunder (irrespective of any of the circumstances referred to in the
preceding sentence), or any error, omission, interruption, loss or delay in
transmission or delivery of any draft, notice or other communication under or
relating to the Letter of Credit (including any document required to make a
drawing thereunder), any error in interpretation of technical terms or any
consequence arising from causes beyond the control of the Funding Bank; PROVIDED
that the foregoing shall not be construed to excuse the Funding Bank from
liability to any Participating Bank to the extent of any direct damages (as
opposed to consequential damages, claims in respect of which are hereby waived
by each Participating Bank to the extent permitted by applicable law) suffered
by such Participating Bank that are caused by the Funding Bank's failure to
exercise care when determining whether drafts and other documents presented
under the Letter of Credit comply with the terms thereof. The parties hereto
expressly agree that, in the absence of gross negligence or wilful misconduct on
the part of the Funding Bank (as finally determined by a court of competent
jurisdiction), the Funding Bank shall be deemed to have exercised care in each
such determination. In furtherance of the foregoing and without limiting the
generality thereof, the parties agree that, with respect to documents presented
which appear on their face to be in substantial compliance with the terms of the
Letter of Credit, the Funding Bank may, in its sole discretion, either accept
and make payment upon such documents without responsibility for

                                                                              15


further investigation, regardless of any notice or information to the contrary,
or refuse to accept and make payment upon such documents if such documents are
not in strict compliance with the terms of the Letter of Credit.

                        (c) Upon receipt of a payment from the Issuer pursuant
to Section 2(a) hereof, the Funding Bank shall promptly transfer to each
Participating Bank such Participating Bank's pro rata share (determined in
accordance with such Participating Bank's Participation Percentage) of such
payment based on such Participating Bank's pro rata share (determined as
aforesaid) of amounts paid pursuant to Section 5(a) hereof, and not previously
reimbursed by the Issuer pursuant to Section 2(a) hereof. All payments due to
the Participating Banks from the Funding Bank pursuant to this paragraph (c)
shall be made to the Participating Banks if, as, and to the extent possible,
when the Funding Bank receives payments in respect of drawings under the Letter
of Credit pursuant to Section 2(a) hereof, and in the same funds in which such
amounts are received; PROVIDED that if any Participating Bank to whom the
Funding Bank is required to transfer any such payment (or any portion thereof)
pursuant to this paragraph (c) does not receive such payment (or portion
thereof) prior to 3:00 p.m. (London time) on the Business Day on which the
Funding Bank received such payment from the Issuer (which payment, if received
by the Funding Bank after 2:00 p.m. (London time) on any Business Day, shall be
deemed, for the purposes of this proviso, to have been received on the next
succeeding Business Day), the Funding Bank agrees to pay to such Participating
Bank, along with its payment of the portion of such payment due to such
Participating Bank, interest on such amount at a rate per annum equal to, for
the period from and including such Business Day to but excluding the date such
amount is paid in full, the LIBO Rate applicable to the reimbursed drawing under
the Letter of Credit. If, in connection with any case or other proceeding
seeking liquidation, reorganization or other relief with respect to the Issuer
or its debts under any bankruptcy, insolvency or other similar law now or
hereafter in effect, the Funding Bank shall be required to return to the Issuer
or to any trustee, receiver, liquidator, custodian or other similar official all
or any portion of such payments or interest, each Participating Bank shall, upon
demand of the Funding Bank, forthwith return to the Funding Bank any amounts
transferred to such Participating Bank by the Funding Bank in respect thereof
pursuant to this paragraph (c).

                        (d) The Funding Bank will exercise and give the same
care and attention to the Letter of Credit as it gives


<PAGE>

                                                                              16


to its other letters of credit and similar obligations, and each Participating
Bank agrees that the Funding Bank's sole liability to each Participating Bank
shall be (i) to distribute promptly, as and when received by the Funding Bank,
and in accordance with the provisions of paragraph (c) above, such Participating
Bank's pro rata share (determined in accordance with such Participating Bank's
Participation Percentage) of any payments to the Funding Bank by the Issuer
pursuant to Section 2(a) hereof in respect of drawings under the Letter of
Credit, (ii) to exercise or refrain from exercising any right or to take or to
refrain from taking any action under this Agreement or the Letter of Credit as
may be directed in writing by the Required Banks (or such higher percentage of
Banks as may be otherwise expressly required under this Agreement) or the
Administrating Bank acting on behalf of such Banks and (iii) as otherwise
expressly set forth herein. The Funding Bank shall not be liable for any action
taken or omitted at the request or with approval of the Required Banks or of the
Administrating Bank acting on behalf of the Required Banks or for the
nonperformance of the obligations of any other party under this Agreement, any
of the Transaction Documents or any other document contemplated hereby or
thereby. Without in any way limiting any of the foregoing, the Funding Bank may
rely upon the advice of counsel concerning legal matters and upon any written
communication or any telephone conversation which it believes to be genuine or
to have been signed, sent or made by the proper person and shall not be required
to make any inquiry concerning the performance by the Issuer, the Collateral
Agent, Holdings, any Owner or any other Person of any of their respective
obligations and liabilities under or in respect of this Agreement, the
Transaction Documents or any other documents contemplated hereby or thereby. The
Funding Bank shall not have any obligation to make any claim, or assert any
Lien, upon any property held by the Funding Bank or assert any offset there
against unless expressly directed to do so by the Required Banks or the
Administrating Bank acting on behalf of the Required Banks. The Funding Bank and
its Affiliates may accept deposits from, make loans or otherwise extend credit
to, and generally engage in any kind of business with the Issuer or any of its
Affiliates, or any other Person, and receive payment on such loans or extensions
of credit and otherwise act with respect thereto freely and without
accountability in the same manner as if this Agreement and the transactions
contemplated hereby were not in effect. Without limiting any of the foregoing,
the Funding Bank agrees for the exclusive benefit of the Participating Banks
that (x) it will not give notice of a Date of Early Termination under the Letter
of Credit without


<PAGE>

                                                                              17


a writing executed by the Required Banks or executed by the Administrating Bank
on behalf of the Required Banks directing it to give such notice (which writing
shall specify the Date of Early Termination to be given in such notice) and (y)
if a Reimbursement Event of Default has occurred and is continuing, upon receipt
of such a writing, it will give such notice as provided in the Letter of Credit.

                        (e)  The Funding Bank makes no representation and
shall have no responsibility with respect to: (i) the genuineness, legality,
validity, binding effect or enforceability of this Agreement, any of the
Transaction Documents or any other documents contemplated hereby or thereby;
(ii) the truthfulness or accuracy of any of the representations contained in
this Agreement, any of the Transaction Documents or any other documents
contemplated hereby or thereby; (iii) the collectibility of any amounts due
under this Agreement; (iv) the financial condition of the Issuer, Holdings, any
Owner or any other Person; and (v) any act or omission of the Collateral Agent
with respect to its use of the Letter of Credit. Each Participating Bank
acknowledges and agrees that such Participating Bank has been, and will continue
to be, solely responsible for making its own independent appraisal of and
investigation into the financial condition, affairs, status and nature of the
Issuer, Holdings and the Owners and for making its own credit decision in taking
or not taking any action, including without limitation, entering into this
Agreement.

                 (f) To the extent that the Funding Bank is not
reimbursed and indemnified by the Issuer under Section 19 or Section 20 hereof,
each Participating Bank severally agrees to reimburse and indemnify the Funding
Bank on demand, pro rata in accordance with such Participating Bank's
Participation Percentage, for and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by, or asserted against, the Funding Bank, in any way relating to or arising out
of the Letter of Credit, or any action taken or omitted by the Funding Bank
under or in connection with this Agreement or the Letter of Credit; PROVIDED,
HOWEVER, that such Participating Bank shall not be liable for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements determined by the final, non-appealable
judgment of a court of competent jurisdiction to have resulted from the Funding
Bank's gross negligence or wilful misconduct or for the Issuer's failure to pay

                                                                              18


interest thereon. Each Participating Bank's obligations under this paragraph (f)
shall survive the termination of this Agreement and the Letter of Credit.
Nothing in this paragraph (f) is intended to limit any Participating Bank's
reimbursement obligation contained in paragraph (a) above.


                        (g) Each Participating Bank agrees that if it should
receive any amount in respect of its participation other than from the Funding
Bank pursuant to paragraph (c) above and other than as contemplated by Section
3, Section 4, Section 17(a), Section 19, or Section 20 hereof, such
Participating Bank will remit all of the same to the Administrating Bank to
distribute to the Participating Banks pro rata in accordance with their
Participation Percentages.

                        SECTION 6. PAYMENTS. (a) All payments by the Issuer or
the Participating Banks to the Funding Bank pursuant to this Agreement shall be
made in lawful currency of the United States and in immediately available funds
to the Funding Bank's account maintained with the Administrating Bank for such
purpose, or to such other account as the Funding Bank shall notify the Issuer
and each Participating Bank in writing. All payments by the Funding Bank, the
Issuer, or the Administrating Bank to a Participating Bank shall be made in
lawful currency of the United States and in immediately available funds at the
address of such Participating Bank set forth below the name of such
Participating Bank on the signature pages hereof, or at such other address as
any Participating Bank shall notify each of the Funding Bank, the Issuer, and
the Administrating Bank in writing.

                        (b) Whenever any payment under this Agreement shall be
due on a day that is not a Business Day, the date for payment thereof shall be
extended to the next succeeding Business Day, and any interest payable thereon
shall be payable for such extended time at the specified rate.

                        (c) Interest payable under Sections 2(a), 5(a) and 5(c)
hereof and the fees payable under Section 3 hereof shall be computed on the
basis of a year of 360 days and paid for the actual number of days elapsed
(including the first day but excluding the last day).

                        (d) Except as otherwise expressly provided in Section 3,
4 or 5 hereof, all payments hereunder from the Issuer to the Participating
Banks, from the Funding Bank to the Participating Banks, from the Participating
Banks to the Funding Bank and from the Participating Banks to the

Administrating Bank shall be made pro rata among the Participating Banks in
accordance with the Participation Percentages of such Participating Banks.

                        SECTION 7.  ISSUANCE OF THE LETTER OF CREDIT;
CONDITIONS PRECEDENT TO ISSUANCE. (a) Subject to satisfaction of the conditions
precedent set forth in subsections (b), (c), (d) and (e) of this Section 7, the
Funding Bank shall issue the Letter of Credit to the Collateral Agent in the
Maximum Credit Amount on the Issue Date (such date or such later date on which
the conditions precedent are satisfied and the Letter of Credit is issued being
herein called the "Date of Issuance" of the Letter of Credit). The Letter of
Credit shall be effective on its Date of Issuance and shall expire on its
Termination Date.

                        (b) As a condition precedent to the issuance of the
Letter of Credit, the Administrating Bank and each Bank shall have received on

            Transaction Documents;

                        (c) the existence of any claim, setoff, defense or other
            rights which the Issuer, Holdings or any Owner may have at any time
            against any of the Collateral Agent, the Funding Bank, the

            entity, whether in connection with this Agreement, the Trans action
            Documents or any other documents contemplated hereby or thereby or
            any unrelated transactions;

                        (d) any draft or other document presented under the
            Letter of Credit, proving to be forged, fraudulent, invalid or
            insufficient in any respect or any statement therein being untrue or
            inaccurate in any respect;

                        (e) payment by the Funding Bank under the Letter of
            Credit against presentation of a draft or certifi cate which does
            not comply with the terms of the Letter of Credit; or

                        (f) any other act or omission to act or delay of any
            kind of the Funding Bank, the Participating Banks, the
            Administrating Funding Bank or any other Person or any other event
            or circumstance whatsoever, whether or not similar to any of the
            foregoing, that might, but for the provisions of this Section,

Banks nor the Funding Bank, nor any of their respective directors, officers,

interpretation of technical terms or any consequence arising from causes beyond
the control of the Funding Bank; PROVIDED that the foregoing shall not be
construed to excuse the Funding Bank from liability to the Issuer to the extent
of any direct damages (as opposed to consequential damages, claims in respect of
which are hereby waived by the Issuer to the extent permitted by applicable law)
suffered by the Issuer that are caused by the Funding Bank's failure to

exercise care when determining whether drafts and other documents presented
under the Letter of Credit comply with the terms thereof. The parties hereto
expressly agree that, in the absence of gross negligence or wilful misconduct on
the part of the Funding Bank (as finally determined by a court of competent
jurisdiction), the Funding Bank shall be deemed to have exercised care on each
such determination. In furtherance of the foregoing and without limiting the
generality thereof, the parties agree that, with respect to documents presented
which appear on their face to be in substantial compliance with the terms of the
Letter of Credit, the Funding Bank may, in its sole discretion, either accept
and make payment upon such documents without responsibility for further
investigation, regardless of any notice or information to the contrary, or
refuse to accept and make payment upon such documents if such documents are not
in strict compliance with the terms of the Letter of Credit.

                        SECTION 10.  REPRESENTATIONS AND WARRANTIES.  The
Issuer, Holdings and each of the Owners represents and warrants as follows:

Issuer is a public limited company duly organized, validly existing and in good
standing under the laws of the Isle of Man, is duly qualified to do business as
a foreign corporation in and is in good standing under the laws of each

Transaction Documents to which it is a party, and has all corporate powers and
all material governmental licenses, authorizations, consents and approvals
required to carry on its business as now conducted.

Applicable Law, or any such indenture, mortgage, lease or other agreement or
instrument which

materially adversely affects its ability to perform its obligations under this
Agreement or any Transaction Document to which it is, or is to become, a party.

                        (d) GOVERNMENTAL ACTIONS. No action, consent or approval
of, registration or filing with or any other action by any Governmental
Authority (a "Governmental Action") is or will be required in connection with
the execution, delivery or performance by it, or the consummation by it of the
transactions contemplated by this Agreement or any Transaction Document to which
it is, or is to become, a party, except such Governmental Actions as have been
duly obtained, given or accomplished.

                        (e) EXECUTION AND DELIVERY. This Agreement and the
Transaction Documents to which it is a party have been duly executed and

Transaction Documents, or materially and adversely affect any of the related

                        SECTION 11.  COVENANTS.  Each of the covenants set


<PAGE>

                                                                              26


forth in Articles 4 and 5 of each Indenture as in effect on the date hereof,
including the related definitions, is hereby incorporated herein by reference,
MUTATIS MUTANDIS. The Issuer agrees to comply with each such covenant for the
benefit of the Funding Bank, the Administrating Bank and the Participating Banks
as if set forth in full herein, and the Banks shall be entitled to enforce such
covenants as if set forth in full herein.

                        SECTION 12.  GUARANTEES OF THE OWNERS.
(a) GUARANTEES. (i) Each Guarantor hereby unconditionally and irrevocably
guarantees, jointly and severally, to the Administrating Bank, the Funding Bank,
each Participating Bank and their respective successors and assigns (A) the full
and punctual payment of principal of and interest on the reimbursement
obligations under this Agreement when due, whether at maturity, by acceleration
or otherwise, and all other monetary obligations of the Issuer and the
Guarantors under this Agreement and (B) the full and punctual performance within
applicable grace periods of all other obligations of the Issuer and the
Guarantors under this Agreement (all the foregoing being hereinafter
collectively called the "Obligations"). Each Guarantor further agrees that the
Obligations may be extended or renewed, in whole or in part, without notice or
further assent from such Guarantor and that such Guarantor will remain bound
under this Section 12 notwithstanding any extension or renewal of any
Obligation.

                        (ii)  Each Guarantor waives presentation to,
demand of, payment from and protest to the Issuer of any of the Obligations and
also waives notice of protest for nonpayment. Each Guarantor waives notice of
any default under this Agreement or the Obligations. The obligations of each
Guarantor hereunder shall not be affected by (A) the failure of the
Administrating Bank, the Funding Bank or any Participating Bank to assert any
claim or demand or to enforce any right or remedy against the Issuer or any
other Person under this Agreement, any Transaction Document or any other
agreement or otherwise; (B) any extension or renewal of any thereof; (C) any
rescission, waiver, amendment or modification of any of the terms or provisions
of this Agreement, any Transaction Document or any other agreement; (D) the
release of any security held by the Administrating Bank, the Funding Bank or any
Participating Bank for the Obligations; (E) the failure of the Administrating
Bank, the Funding Bank or any Participating Bank to exercise any right or remedy
against any other guarantor of the Obligations; or (F) any change in the
ownership of such Guarantor.

                                                                              27


                        (iii)  Each Guarantor further agrees that its
Guarantee herein constitutes a guarantee of payment, performance and compliance
when due (and not a guarantee of collection) and waives any right to require
that any resort be had by the Administrating Bank, the Funding Bank or any
Participating Bank to any security held for payment of the Obligations.

                        (iv)  Except as expressly set forth in
Sections 12(b) hereof, the obligations of each Guarantor hereunder shall not be
subject to any reduction, limitation, impairment or termination for any reason,
including any claim of waiver, release, surrender, alteration or compromise, and
shall not be subject to any defense of setoff, counterclaim, recoupment or
termination whatsoever or by reason of the invalidity, illegality or
unenforceability of the Obligations or otherwise. Without limiting the
generality of the foregoing, the obligations of each Guarantor herein shall not
be discharged or impaired or otherwise affected by the failure of the
Administrating Bank, the Funding Bank or any Participating Bank to assert any
claim or demand or to enforce any remedy under this Agreement, any Transaction
Document or any other agreement, by any waiver or modification of any thereof,
by any default, failure or delay, willful or otherwise, in the performance of
the obligations, or by any other act or thing or omission or delay to do any
other act or thing which may or might in any manner or to any extent vary the
risk of such Guarantor or would otherwise operate as a discharge of such
Guarantor as a matter of law or equity.

                        (v)  Each Guarantor further agrees that its
Guarantee herein shall continue to be effective or be reinstated, as the case
may be, if at any time payment, or any part thereof, of principal of or interest
on any Obligation is rescinded or must otherwise be restored by the
Administrating Bank, the Funding Bank or any Participating Bank upon the
bankruptcy or reorganization of the Issuer or otherwise.

                        (vi) In furtherance of the foregoing and not in
limitation of any other right which the Administrating Bank, the Funding Bank or
any Participating Bank has at law or in equity against any Guarantor by virtue
hereof, upon the failure of the Issuer to pay the principal of or interest on
any Obligation when and as the same shall become due, whether at maturity, by
acceleration or otherwise, or to perform or comply with any other Obligation,
each Guarantor hereby promises to and will, upon receipt of written demand by
the Administrating Bank, forthwith pay, or cause to be


<PAGE>

                                                                              28


paid, in cash, to the Administrating Bank, the Funding Bank and each
Participating Bank, an amount equal to the sum of (i) the unpaid amount of such
Obligations, (ii) accrued and unpaid interest on such Obligations (but only to
the extent not prohibited by law) and (iii) all other monetary Obligations of
the Issuer or the Guarantors to the Administrating Bank, the Funding Bank and
each Participating Bank.

                        (vii)  Each Guarantor agrees that, as between it,
on the one hand, and the Administrating Bank, the Funding Bank or any
Participating Bank, on the other hand, (A) the maturity of the Obligations
Guaranteed hereby may be accelerated by terminating the Letter of Credit as
provided in Section 14 hereof for the purposes of such Guarantor's Guarantee
herein, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the Obligations guaranteed hereby, and (B) in
the event of any termination of the Letter of Credit as provided in Section 14
hereof, such Obligations (whether or not due and payable) shall forthwith become
due and payable by such Guarantor for the purposes of this Section.

                        (viii)  Each Guarantor also agrees to pay any and
all costs and expenses (including reasonable attorneys' fees) incurred by the
Administrating Bank, the Funding Bank or any Participating Bank in enforcing any
rights under this Section.

                        (b)  LIMITATION ON LIABILITY.  Any term or
provision of this Agreement to the contrary notwithstanding, the maximum
aggregate amount of the Obligations guaranteed hereunder by any Owner shall not
exceed the maximum amount that can be hereby guaranteed without rendering the
guaranty under this Agreement, as it relates to such Owner, voidable under
applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.

                        (c)  SUCCESSORS AND ASSIGNS.  This Section 12
shall be binding upon each Guarantor and its successors and assigns and shall
enure to the benefit of the successors and assigns of the Administrating Bank,
the Funding Bank and each Participating Bank and, in the event of any transfer
or assignment of rights by the Administrating Bank, the Funding Bank or any
Participating Bank, the rights and privileges conferred upon that party in this
Agreement and in the Transaction Documents shall automatically extend to and be
vested in such transferee or assignee, all subject to the terms and conditions
of this Agreement.

                                                                              29


                        (d)  NO WAIVER.  Neither a failure nor a delay on
the part of any of the Administrating Bank, the Funding Bank or any
Participating Bank in exercising any right, power or privilege under this
Section 12 shall operate as a waiver thereof, nor shall a single or partial
exercise thereof preclude any other or further exercise of any right, power or
privilege. The rights, remedies and benefits of the Administrating Bank, the
Funding Bank or any Participating Bank herein expressly specified are cumulative
and not exclusive of any other rights, remedies or benefits which either may
have under this Section 12 at law, in equity, by statute or otherwise.

                        (e)  MODIFICATION.  No modification, amendment or
waiver of any provision of this Section 12, nor the consent to any departure by
any Guarantor therefrom, shall in any event be effective unless the same shall
be in writing and signed by the Administrating Bank, and then such waiver or
consent shall be effective only in the specific instance and for the purpose for
which given. No notice to or demand on any Guarantor in any case shall entitle
such Guarantor to any other or further notice or demand in the same, similar or
other circumstances.

                        SECTION 13.  REIMBURSEMENT EVENTS OF DEFAULT.  The
following events shall be "Reimbursement Events of Default" hereunder unless
waived by the Required Banks pursuant to Section 14 hereof:

                        (i) the Issuer shall (a) fail to pay when due any amount
            payable under Section 2(a) hereof, or (b) fail to pay any amount
            payable under Section 3 hereof within 5 Business Days after the same
            shall become due; or

                        (ii) an "Event of Default" (as such term is defined in
            the First Priority Indenture or the Second Priority Indenture, as
            the case may be) shall have occurred and be continuing under the
            First Priority Indenture or the Second Priority Indenture; or

                        (iii) the Issuer shall fail to make any payment in
            respect of the Notes, or to make any payment of any interest or
            premium thereon, when due (whether by scheduled maturity, required
            prepayment, acceleration, demand or otherwise); or

                        (iv) the Issuer, Holdings or any Owner shall fail to
            observe or perform any covenant or agreement contained in this
            Agreement (other than those covered by clauses (i), (ii) and (iii)
            above) for 30 days after

            written notice thereof has been given to the Issuer by
            the Administrating Bank or any Participating Bank; or

                        (v) any representation, warranty, certification or
            statement made by the Issuer, Holdings or any Owner in this
            Agreement or in any certificate, financial statement or other
            document delivered pursuant to this Agreement shall prove to have
            been incorrect or misleading in any material respect when made; or

                        (vi) any material provision of this Agreement shall at
            any time for any reason cease to be valid and binding upon the
            Issuer, Holdings or any Owner, or shall be declared to be null and
            void, or the validity or enforceability thereof shall be contested
            by the Issuer, Holdings, any Owner or any Governmental Authority, or
            the Issuer, Holdings or any Owner shall deny that it has any or
            further liability or obligation under this Agreement; or

                        (vii) the Issuer, Holdings or any Owner shall fail to
            make any payment of any amount in respect of any Indebtedness, or to
            make any payment of any interest or premium thereon, when due

            demand or otherwise) and such failure shall continue after the
            applicable grace period, if any, specified in such agreement or
            instrument relating to such Indebtedness, or any other default under
            any agreement or instrument relating to any Indebtedness, or any
            other event, shall occur and shall continue after the applicable
            grace period, if any, specified in such agreement or instrument, if
            the effect of such default or event is to enable the holder of such
            Indebtedness to accelerate the maturity of any Indebtedness if the
            total of all such Indebtedness which has been accelerated and any
            additional Indebtedness which has become due and not been paid shall
            exceed $5,000,000 or any Indebtedness the aggregate principal amount
            of which is greater than $5,000,000 shall be declared due and
            payable, or required to be prepaid prior to the stated maturity
            thereof; or

                        (xi) this Agreement or any Security Agreement shall for
            any reason cease to be, or be asserted by any of the Issuer,

<PAGE>

                                                                              32


            Holdings or any Owner not to be, a valid, first priority perfected
            security interest (subject to no liens, except Permitted Liens) in
            the Collateral as defined under each such agreement.

                        If a Reimbursement Event of Default occurs and is
continuing, the Required Banks may, in their sole discretion, by notice to the
Issuer and the Collateral Agent cause the Funding Bank to terminate the Letter
of Credit as provided therein.

                        SECTION 14.  AMENDMENTS AND WAIVERS.  Neither this
Agreement nor any provision hereof (including, without limitation, the Letter of
Credit) may be waived, amended or modified except pursuant to an agreement or
agreements in writing entered into by the Issuer and the Required Banks;
PROVIDED, HOWEVER, that no such agreement shall (i) change the Maximum Credit
Amount, or extend or advance the maturity of the Letter of Credit or the dates
for the reimbursement of drawings under the Letter of Credit or the payment of
interest thereon or reduce the rate of interest on any unreimbursed drawings,
(ii) change the Participation Percentage of any Participating Bank or the fees
provided for in Section 3 hereof or (iii) amend or modify the provisions of this
Section 14, Section 2 hereof, Section 6(d) hereof or Section 9 hereof, the
proviso in Section 18 or the definition of "Required Banks", in each case
without the prior written consent of each Participating Bank and the Funding
Bank; PROVIDED, FURTHER that no such agreement shall (I) modify or otherwise
affect the rights or duties of the Funding Bank hereunder, (II) amend or modify
the provisions of Sections 5 hereof or (III) change the fees provided for in
Section 3(a) hereof, without the written consent of the Funding Bank or amend,
modify or otherwise affect the rights or duties of the Administrating Bank
hereunder, without the written consent of the Administrating Bank; and PROVIDED,
FURTHER that no such agreement shall amend or modify the provisions of Section
12 hereof without the written consent of each of the Owners. The Administrating
Bank and each Bank shall be bound by any modification or amendment authorized by
this Section 14, and any consent by any Participating Bank pursuant to this
Section 14 shall bind any successor Participating Bank acquiring a participation
from it whether or not such successor Participating Bank has received actual
notice thereof.

                 SECTION 15. NOTICES. All notices, requests and
other communications to any party hereunder shall be in
writing (including telecopy or other facsimile transmission)


<PAGE>

                                                                              33


and shall be given to such party, addressed to it, at its address or facsimile
number set forth below the name of such party on the signature pages hereof or
such other address or facsimile number as such party may hereafter specify for
that purpose by notice to the other parties. Each such notice, request or
communication shall be effective (i) if given by facsimile, when such facsimile
is transmitted to the facsimile number specified above, (ii) if given by mail
upon receipt but not later than 5 days after such communication is deposited in
the mails with first-class postage prepaid, addressed as aforesaid, or (iii) if
given by any other means, when delivered at the address for notices described
above.

                 SECTION 16. NO WAIVER; REMEDIES. No failure on
the part of the Administrating Bank or any Bank to exercise, and no delay in
exercising, any power or right hereunder for any period of time shall operate as
a waiver thereof nor shall any single or partial exercise of any such right or
power preclude any other or further exercise thereof or the exercise of any
other right. The rights and remedies herein provided to the Administrating Bank
and the Banks are cumulative and not exclusive of any other rights or remedies
which the Administrating Bank or any Bank may otherwise have. No waiver of any
provision of this Agreement nor consent to any departure by the Issuer therefrom
shall in any event be effective unless the same shall be authorized as provided
in Section 14 above, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given. No notice to or
demand on the Issuer, Holdings or any Owner in any case shall entitle the
Issuer, Holdings or any Owner to any other or further notice or demand in
similar or other circumstances.

                   SECTION 17. RIGHT OF SETOFF. (a) If a Reim-
bursement Event of Default shall have occurred and be continuing, each Bank is
hereby authorized at any time and from time to time, to the fullest extent
permitted by law, to set off and apply any and all deposits (general or special,
time or demand, provisional or final) at any time held and other indebtedness at
any time owing by such Bank to or for the credit or the account of the Issuer,
Holdings or any Owner against any of and all the obligations of the Issuer,
Holdings or any Owner now and hereafter existing under this Agreement,
irrespective of whether or not such Bank shall have made any demand under this
Agreement and although such obligations may be unmatured. Each Bank agrees
promptly to notify the Issuer after any such setoff and application made by such
Bank, but the failure to give such notice shall not affect the validity of such
setoff and


<PAGE>

                                                                              34


application. The rights of each Bank under this Section are in addition to other
rights and remedies (including, without limitation, other rights of setoff)
which such Bank may have.

                  (b) Each Participating Bank agrees that if it
shall, through the exercise of a right of banker's lien, setoff or counterclaim
against the Issuer, including, but not limited to, a secured claim under Section
506 of Title 11 of the United States Code or other security or interest arising
from, or in lieu of, such secured claim, received by such Participating Bank
under any applicable bankruptcy, insolvency or other similar law or otherwise,
obtain payment (voluntary or involuntary) in respect of amounts paid by it
pursuant to Section 5(a) as a result of which the unreimbursed portion of
Section 5(a) payments made by it shall be proportionately less (determined in
accordance with each Participating Bank's Participation Percentage) than the
unreimbursed portion of Section 5(a) payments made by any other Participating
Bank, it shall be deemed to have simultaneously purchased from such other
Participating Bank a participation in the unreimbursed portion of Section 5(a)
payments made by such other Participating Bank, so that the aggregate
unreimbursed portion of Section 5(a) payments made by it and participations in
the unreimbursed portion of Section 5(a) payments made by each other
Participating Bank and held by it shall be in the same proportion (determined in
accordance with each Participating Bank's Participation percentage) to the
aggregate unreimbursed portion of Section 5(a) payments made by all
Participating Banks as the principal amount of the unreimbursed portion of
Section 5(a) payments made by it prior to such exercise of banker's lien, setoff
or counterclaim was to the unreimbursed portion of all Section 5(a) payments
made by all Participating Banks prior to such exercise of banker's lien, setoff
or counterclaim; PROVIDED, HOWEVER, that if any such purchase or purchases or
adjustments shall be made pursuant to this Section 17(b) and the payment giving
rise thereto shall thereafter be recovered, such purchase or purchases or
adjustments shall be rescinded to the extent of such recovery and the purchase
price or prices or adjustment restored without interest. The Issuer expressly
consents to the foregoing arrangements and agrees that any Participating Bank
holding a participation in an unreimbursed portion of Section 5(a) payment
deemed to have been so purchased may exercise any and all rights of banker's
lien, setoff or counterclaim with respect to any and all moneys owing by it to
such Participating Bank as fully as if such Participating Bank held an
unreimbursed portion of Section 5(a) payment in the amount of such

                                                                              35

participation.

                        SECTION 18. CONTINUING OBLIGATION. Except with respect
to Sections 19, and 20, the obligations of the Issuer, Holdings and each of the
Owners under this Agreement shall continue until the later of (i) the
Termination Date of the Letter of Credit or (ii) the date upon which all amounts
due and owing to the Administrating Bank and the Banks hereunder shall have been
paid in full and shall (a) be binding upon the Issuer, Holdings and each of the
Owners and their respective successors and assigns and (b) inure to the benefit
of and be enforceable by the Banks and their successors, transferees and
assigns; PROVIDED, HOWEVER, that the Issuer may not assign all or any part of
this Agreement without the prior written consent of the Funding Bank and the
Participating Banks.

                        SECTION 19.  COSTS, EXPENSES AND TAXES.  The
Issuer agrees to pay upon demand therefor, whether or not the transactions
contemplated herein are consummated, all reasonable costs and expenses of the
Administrating Bank in connection with the preparation, execution, delivery,
filing and administration of this Agreement and any other documents which may be
delivered in connection with this Agreement, including, without limitation, the
reasonable fees, disbursements and other charges of special counsel for the
Administrating Bank and the Funding Bank with respect thereto and with respect
to advising the Administrating Bank and the Funding Bank as to their rights and
responsibilities under this Agreement and to pay all reasonable counsel fees and
expenses that may be incurred by the Administrating Bank and each of the Banks
in connection with any Reimbursement Event of Default or the enforcement of this
Agreement and such other documents which may be delivered in connection with
this Agreement or, in the case of Administrative Bank and the Funding Bank, any
waiver or amendment of this Agreement. In addition, the Issuer agrees to pay any
and all stamp and other taxes and fees payable or determined to be payable in
connection with the execution, delivery, filing and recording of this Agreement
and such other documents and agree to hold the Administrating Bank and the Banks
harmless from and against any and all liabilities with respect to or resulting
from any delay in paying or omission to pay such taxes and fees. Without
prejudice to the survival of any other obligation of the Issuer hereunder, the
obligations of the Issuer contained in this Section 19 shall survive the payment
in full of amounts payable by the Issuer under Section 2(a) hereof and the
termination of the Letter of Credit and this Agreement.

                                                                              36

                 SECTION 20. INDEMNIFICATION. The Issuer hereby
agrees to indemnify and hold harmless the Administrating Bank and each Bank and
their respective officers, directors, affiliates, employees and agents (each, an
"indemnitee") from and against any and all claims, damages, losses, liabilities,
costs or expenses whatsoever which an indemnitee may incur (or which may be
claimed against an indemnitee by any Person or entity whatsoever) (i) by reason
of any inaccuracy in any material respect, or untrue statement or alleged untrue
statement of any material fact contained or incorporated by reference in any
offering document distributed by or on behalf of the Issuer in connection with
the issuance of the Notes or in any supplement or amendment thereto, or the
omission or alleged omission to state therein a material fact necessary to make
such statements, in the light of the circumstances under which they are or were
made, not misleading; (ii) by reason of or in connection with the execution,
delivery and performance of this Agreement and the Transaction Documents; or
(iii) by reason of or in connection with the execution and delivery or transfer
of, or payment or failure to make lawful payment under, the Letter of Credit;
PROVIDED that the Issuer shall not be required to indemnify an indemnitee for
any claims, damages, losses, liabilities, costs or expenses to the extent
determined by the final, non-appealable judgment of a court of competent
jurisdiction to have resulted from the wilful misconduct or gross negligence of
such indemnitee. Without prejudice to the survival of any other obligation of
the Issuer hereunder, the indemnities and obligations of the Issuer contained in
this Section 20 shall survive the payment in full of amounts payable by the
Issuer under Section 2(a) hereof and the termination of the Letter of Credit and
this Agreement or the substitution of any of the Banks pursuant to Sections 4(e)
or (f) hereof.

                        SECTION 21.  SALES OF PARTICIPATIONS.  (a)  With-
out the consent of the Funding Bank, the Administrating Bank, the Issuer,
Holdings, any Owner or any other Participating Bank, each Participating Bank may
grant participations in its participation in the Letter of Credit (each Person
to which a participation is granted being called a "Participant") and in such
event such Participating Bank will, in its own name and as agent for any such
Participant, enforce all rights and interests of any Participant under this
Agreement, and accept all performances required of the Issuer under this
Agreement; PROVIDED, HOWEVER, that such Participating Bank shall remain entitled
to exercise any right, remedy and power hereunder (other than with respect to
(i) the Maximum Credit Amount or


<PAGE>

                                                                              37


the effective Participation Percentage of such Participant, (ii) the maturity of
the Letter of Credit or the dates for the reimbursement of drawings under the
Letter of Credit or the payment of interest thereon, (iii) the rate of interest
on unreimbursed drawings, or (iv) the fees to be paid hereunder), and shall
remain fully obligated to the Funding Bank as provided herein. If, at the time
of a grant of a participation pursuant to this Section 21(a), such grant would
result in a claim for compensation pursuant to Sections 4(a), (b), or (c) hereof
materially greater than that to which the Participating Bank granting such
participation is entitled, such grant shall be subject to the consent of the
Issuer (which consent shall not be unreasonably withheld).

                        (b) With the prior written consent of the Administrating
Bank and the Funding Bank (which consent shall not be unreasonably withheld),
any Participating Bank may cause all or a portion of its obligations hereunder
to be assumed by another financial institution, and upon the execution of an
Assignment and Acceptance, such financial institution shall become a
"Participating Bank" for purposes of this Agreement and shall be entitled to the
rights, privileges and obligations of a Participating Bank hereunder and such
transferring Bank shall be released from its obligations with respect to the
portion of its participation so assumed.

                        SECTION 22. ADMINISTRATING BANK. (a) In order to
expedite the various transactions contemplated by this Agreement, Credit Suisse
First Boston, acting through its London branch, is hereby appointed to act as
Administrating Bank on behalf of the Participating Banks. Each of the
Participating Banks hereby authorizes and directs the Administrating Bank to
take such action on behalf of such Participating Bank under the terms and
provisions of this Agreement and to exercise such powers hereunder as are
specifically delegated to or required of the Administrating Bank by the terms
and provisions hereof, together with such powers as are reasonably incidental
thereto. The Administrating Bank is hereby expressly authorized on behalf of the
Participating Banks, without hereby limiting any implied authority, (i) to
receive on behalf of each of the Participating Banks any payment of fees due to
the Participating Banks hereunder and all other amounts accrued hereunder paid
to the Administrating Bank for the accounts of the Participating Banks, and
promptly to distribute to each Participating Bank its proper share of all
payments so received; (ii) to give notice within a reasonable time on behalf of
each of the Participating Banks to the Issuer of


<PAGE>

                                                                              38


any Reimbursement Event of Default specified in this Agreement of which the
Administrating Bank has actual knowledge acquired in connection with its
capacity as Administrating Bank hereunder; and (iii) to distribute to the
Funding Bank and each Participating Bank copies of all notices, agreements and
other material as provided for in this Agreement as received by the
Administrating Bank.

                        (b) Neither the Administrating Bank nor any of its
directors, officers, employees or agents shall be liable as such for any action
taken or omitted by any of them hereunder except for its or his own gross
negligence or wilful misconduct, nor be responsible for any statement, warranty
or representation herein or the contents of any document delivered in connection
herewith nor be required to ascertain or to make any inquiry concerning the
performance or observance by the Issuer, Holdings or the Owners of any of the
terms, conditions, covenants or agreements of this Agreement. The Administrating
Bank shall not be responsible to the Participating Banks for the due execution,
genuineness, validity, enforceability or effectiveness of this Agreement, the
Letter of Credit or any other instrument to which reference is made herein. The
Administrating Bank shall in all cases be fully protected in acting, or
refraining from acting, in accordance with written instructions signed by the
Required Banks, and, except as otherwise specifically provided herein, such
instructions and any action taken or failure to act pursuant thereto shall be
binding on all the Participating Banks. The Administrating Bank shall, in the
absence of knowledge to the contrary, be entitled to rely on any paper or
document believed by it to be genuine and correct and to have been signed or
sent by the proper person or persons. Neither the Administrating Bank nor any of
its directors, officers, employees or agents shall have any responsibility to
the Issuer or the Funding Bank on account of the failure or delay in performance
or breach by any Participating Bank or the Funding Bank of any of its
obligations hereunder or to any Participating Bank on account of the failure of
or delay in performance or breach by any other Participating Bank, the Funding
Bank or the Issuer of any of their respective obligations hereunder or in
connection herewith. The Administrating Bank may execute any and all duties
hereunder by or through agents or employees and shall be entitled to advice of
legal counsel selected by it with respect to all matters arising hereunder and
shall not be liable for any action taken or suffered in good faith by it in
accordance with the advice of such counsel.

                        (c) With respect to the Participation Percentage


<PAGE>

                                                                              39


of it hereunder, the Administrating Bank, in its individual capacity and not as
the Administrating Bank, shall have the same rights and powers hereunder and
under any other agree ment executed in connection herewith as any other Partici
pating Bank and may exercise the same as though it were not the Administrating
Bank, and the Administrating Bank and its affiliates may accept deposits from,
lend money to and generally engage in any kind of business with the Issuer,
Holdings or the Owners, any Subsidiary or any other affiliate thereof as if it
were not the Administrating Bank.

                        (d) Each Participating Bank agrees (i) to reim burse the
Administrating Bank in the amount of such Partici pating Bank's pro rata share
(determined in accordance with such Participating Bank's Participation
Percentage) of any expenses incurred for the benefit of the Participating Banks
by the Administrating Bank, including counsel fees and compensation of agents
and employees paid for services rendered on behalf of the Participating Banks,
not reim bursed by the Issuer and (ii) to indemnify and hold harmless the
Administrating Bank and any of its directors, officers, employees or agents, on
demand, in the amount of its pro rata share (determined as aforesaid), from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by or asserted against it in
its capacity as the Administrating Bank or against any of its directors,
officers, employees or agents in any way relating to or arising out of this
Agreement or any action taken or omitted by it or any of them under this
Agreement, to the extent not reimbursed by the Issuer; PROVIDED that no
Participating Bank shall be liable to the Administrating Bank for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements determined by the final, non-appealable
judgment of a court of competent jurisdiction to have resulted from the gross
negligence or wilful misconduct of the Administrating Bank or any of its
directors, officers, employees or agents.

                        (e) Each Participating Bank acknowledges that it has,
independently and without reliance upon the Adminis trating Bank or any other
Participating Bank and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Participating Bank also acknowledges that it will, independently
and without reliance upon the Admin istrating Bank or any other Participating
Bank and based on such documents and information as it shall deem appropriate


<PAGE>

                                                                              40


at the time, continue to make its own decisions in taking or not taking action
under or based upon this Agreement, any related agreement or any document
furnished hereunder.

                        SECTION 23. TERMINATION BY THE ISSUER. The Issuer may,
upon 30 days' written notice to the Administrating Bank, terminate this
Agreement; PROVIDED, HOWEVER, that any such proposed termination shall not be
effective until (i) the Collateral Agent shall have delivered its Letter of
Credit to the Funding Bank for cancelation together with a duly executed request
for cancelation in the form of Exhibit 7 to Exhibit A hereto, and (ii) the
Issuer has paid all fees, expenses and interest accrued hereunder.

                        SECTION 24. SEVERABILITY. Any provision of this
Agreement which is prohibited, unenforceable or not author ized in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition, unenforceability or nonauthorization without invalidating the
remaining provisions hereof or affecting the validity, enforceability or
legality of such provision in any other jurisdiction. The parties shall endeavor
in good-faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid provisions, the economic effect of which comes as close as
possible to that of the invalid, illegal or unenforceable provisions.

                        SECTION 25.  GOVERNING LAW.  This Agreement shall
be governed by, and construed and interpreted in accordance
with, the laws of the State of New York.

                        SECTION 26. JURISDICTION; CONSENT TO SERVICE OF PROCESS.
(a) Each of the Issuer, Holdings and each Owner hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of the Supreme Court of the State of New York sitting in New York

Attn:  Corporate Trust Administration


Ladies and Gentlemen:

                  1. We hereby establish, at the request of Navigator Gas

Termination Date (such term and each other capitalized term used herein and in
Schedules II and III and Exhibits 1, 2, 3, 4, 5, 6, and 7 hereto shall have the
meanings set forth in Schedule I hereto). Of the Maximum Credit Amount, (a) an
amount not to exceed $45,500,000 (such amount, as reduced from time to time in
accordance with the terms hereof, being called the "Interest Portion") may be
drawn on the terms set forth herein to pay (i) accrued interest on the Notes at
the actual rate of interest borne by the Notes (less any Additional Interest),
whether on a scheduled interest payment date or upon the maturity, redemption or
acceleration of the Notes, (ii) unpaid principal and accrued and unpaid interest
on Interest Draws under this Letter of Credit and (iii) fees due under the
Reimbursement Agreement and (b) an amount not to exceed $4,500,000 (such amount,

through its London Branch, as funding bank and administrating bank, the
participating banks from time to time party thereto, Holdings and the Owners (as
the same may be amended, supplemented or modified from time to time, the
"Reimbursement Agreement"). This Letter of Credit is effective immediately and
will expire on the Termination Date.

                  2. The Maximum Available Credit Amount may be reduced at any
time and from time to time upon receipt by us at the address for presentation of
documents set forth below of a copy of the instrument effecting such reduction,
signed by you in the form of Exhibit 1 hereto (a "Reduction Certificate"). Upon
receipt of a Reduction Certificate, the Maximum Available Credit Amount shall be
automatically and permanently reduced by the amount specified as the Reduction
Amount in such certificate (the "Reduction Amount") and the Maximum Drawing
Amounts shall be automatically and permanently reduced as provided in Section
4(e) hereof.

                  3. We hereby irrevocably authorize you to draw on us, in
accordance with the terms and conditions hereinafter set forth, an amount not in
excess of the lesser of (x) the Maximum Available Credit Amount applicable to
the date of such drawing (the "Date of Drawing") and (y)(i) in the case of an
Interest Draw, the Maximum Drawing Amount of the Interest portion applicable to
the Date of Drawing and (ii) in the case of a Working Capital Draw, the Maximum
Drawing Amount of the Working Capital Portion applicable to the Date of Drawing,
in each case as modified in accordance with the next paragraph; PROVIDED,
HOWEVER, that at no time shall we be required to pay any drawing under this
Letter of Credit in excess of the lesser of the Maximum Available Credit Amount
and the Maximum Drawing Amount, in each case as in effect on the applicable Date
of Drawing. Multiple drawings may be made hereunder, provided, that each drawing
honored by us hereunder shall PRO TANTO reduce both (a) the Maximum Available
Credit Amount and (b) the Maximum Drawing Amount of either (i) the Working
Capital Portion or (ii) the Interest Portion, as the case may be, available
under this Letter of Credit. Notwithstanding any other provision of this Letter
of Credit, on the date of each reduction, if any, (a) in the outstanding
principal amount of the Notes or (b) in the stated interest rate of the Notes
(other than any reduction with respect to Additional Interest) the Maximum
Drawing Amounts of the Interest Portion shall be automatically reduced by such
amounts as shall be necessary such that the Interest Portion shall not exceed,
at any date of determination, the Pro Forma Interest Accrual.

         applicable to each Date of Drawing subsequent to such payment shall be
         automatically reduced by an amount equal to the amount of the drawing
         so paid;

                  (b) upon payment by us of each Interest Draw under the Letter
         of Credit, each of (i) the Maximum Available Credit Amount and (ii) the
         Maximum Drawing Amount of the Interest Portion applicable to each Date
         of Drawing subsequent to such payment shall be automatically reduced by
         an amount equal to the amount of the drawing so paid;

                  (c) upon the application by us of amounts paid by the Issuer
         pursuant to Section 2(a) of the Reimbursement Agreement to reimburse
         any Interest Draw or Working Capital Draw hereunder (as such
         application is allocated in accordance with Section 2(b) of the
         Reimbursement Agreement), each of (i) the Maximum Available Credit
         Amount and (ii) the Maximum Drawing Amount of the Portion to which such
         reimbursement is applied applicable to each Date of Drawing subsequent
         to such application shall be automatically increased by the amount of
         such payment(s) allocated as a reimbursement of drawings hereunder;
         PROVIDED, however, that the Maximum Available Credit Amount shall never
         exceed the Maximum Credit Amount;

                  (d) upon the payment by us of any Final Draw under the Letter
         of Credit, each of (i) the Maximum Available Credit Amount and (ii) the

                  prior to such reduction; PROVIDED that such adjustments shall
                  in no event cause the Maximum --------- Drawing Amount to
                  exceed the Maximum Available Credit Amount.

5.       Upon return of this Letter of Credit together with a notice in the form
         of Exhibit 1 hereto, we will promptly initial and attach to this Letter

                                       FOR
                          DELIVERY OF PERFORMANCE BOND
                            AND ACCEPTANCE OF VESSEL

         This Agreement entered into as of this 1st day of August, 1997 by and
among NAVIGATOR HOLDINGS PLC, ("Navigator" as the "Owner"), CHINA SHIPBUILDING
TRADING COMPANY LIMITED ("CSTC") and JIANGNAN SHIPYARD (collectively with CSTC
as the "Builder") and TRACTEBEL GAS ENGINEERING GMBH ("Tractebel" as the Main
Supplier)

         This Agreement is being delivered in connection with five (5) Amended
and Restated Shipbuilding Contracts dated the 26th day of June, 1997 by and
between Navigator and Builder (collectively, "Shipbuilding Contract") as to the
construction of five (5) 22,000 Cubic Meters Liquefied Ethylene Gas Carriers
bearing Hull Nos. 2245, 2246, 2247, 2248 and 2249 (each a "Vessel").

                            W I T N E S S E T H

         NOW THEREFORE, in consideration of the respective representations,
warranties, covenants, agreement and conditions contained herein, and after good
and valuable consideration, the receipt of which is hereby acknowledged, the
parties hereto hereby agree as follows:

         1.       FINANCIAL GUARANTEES.

                  (a) The Builder hereby agrees to deliver to Navigator an
Irrevocable Performance Bond which shall guarantee the performances of the
Builder under the Shipbuilding Contract, provided, however the maximum amount to
be drawn under such Performance Bond shall not exceed US$32,474,600 and shall be
substantially in the form attached as Exhibit A to this Agreement which shall
become Exhibit B to the Shipbuilding Contract. The Performance Bond ("Builder
Performance Bond") shall be issued by Export-Import Bank of China, and the cost
of issuance of such Builder Performance Bond shall be borne equally by the
Builder and Navigator, by an adjustment of the Contract Price as to each Vessel.

                  (b) Tractebel as the Main Supplier agrees to deliver to
Navigator an Irrevocable Performance Bond issued by an Generale de Banque S.A.,
which shall guarantee the performance of the Builder under the Shipbuilding
Contract, provided, however, the maximum amount to be drawn under such
Performance Bond shall not exceed US$16,237,300; provided further, however,
Navigator (or its assignee) shall only be permitted to demand payments under
such Performance Bond after the amounts paid under the Builder Performance Bond
equal to US$32,474,600. The Performance Bond (the "Tractebel Performance Bond")
shall be substantially in the form of Exhibit B to this Agreement which shall
become Exhibit C to the Shipbuilding Contract (as amended to reflect the
obligation of US$16,237,300 and the requirement that a payment in full under the
Builder Performance Bond has been made). Prior to delivery of the Tractebel
Performance Bond, the Builder shall deliver to Tractebel the Payment Guarantees
as set forth in


<PAGE>

paragraph (c) below. The cost of issuance of the Tractebel Performance Bond
shall be borne equally by Tractebel and Navigator.

                  (c) The Builder agrees to deliver to Tractebel Payment
Guarantees covering 95% of the cost of equipment and services to be provided by
Tractebel under the Supply Contract dated February 3, 1997 between the Builder
and Tractebel for supply of the gas plant to be incorporated into the Vessel.
The Payment Guarantee shall be issued by a financial institution acceptable to
Tractebel substantially in the form of Appendix V and Appendix VI set forth in
the Supply Contract. The execution and delivery of the Tractebel Payment
Guarantees by the parties thereto and the payment of the initial installments
due under the Supply Contract by Builder to Tractebel shall be a pre-condition
to Tractebel's obligation to deliver the Tractebel Performance Bond.

                  2. (a) Article III(1)(a)(iii) of the Shipbuilding Contracts
has been modified and provides that: "If delivery of the VESSEL is delayed for
any reason beyond the Original Delay Period, the Builder may elect to further
postpone the delivery of the Vessel beyond the Original Delay Period until March
31, 2001 provided SELLER pays liquidated damages monthly in advance to the BUYER
at the rate of US$18,000 per day from the end of the Original Delay Period to a
date which is 6 months thereafter (the "First Penalty Date"), and US$20,000 per
day from the First Penalty Date to the date which is 6 months thereafter (the
"Second Penalty Date"), and US$22,000 per day from the Second Penalty Date until
March 31, 2001. If the SELLER fails to make any liquidated damages payment,
BUYER, in its sole discretion, may either (i) reject the VESSEL or (ii) waive
its right to receive the payment of liquidated damages and further reduce the
Contract Price for the VESSEL by an amount equal to the liquidated damages which
would have been payable. Notwithstanding any other provision contained in this
Contract to the contrary, this Contract shall be deemed rescinded on April 1,
2001 and the Buyer shall be entitled to receive the amounts set forth in Article
II, Section 7(a) above.

                  "Any waiver by the BUYER of its right to receive liquidated
damages monthly in advance is not a waiver of the BUYER's right to (a) demand
payment of such liquidated damages at a later date, (b) demand monthly advances
as to Liquidated Damages for any subsequent months of delay or (c) reject the
VESSEL at such later date if liquidated damages are not paid upon demand. The
liquidated damages calculated pursuant to this paragraph are in addition to the
reduction in the fifth installment of the Contract Price as calculated pursuant
to (ii) above for the Original Delay Period (as such terms are defined in the
Shipbuilding Contracts)."

                  (b) It is agreed between the Builder and Tractebel that the
liquidated damages to be paid to the Buyer (if any) under Article III, Section
1(a)(iii) of the Shipbuilding Contract shall be shared between the Builder and
Tractebel in the proportion of 2/3 for the Builder and 1/3 for Tractebel except
if the delays causing the liquidated damages are due to force majeure taking
place either in China or in Germany or due to the willful acts of either the
Builder or Tractebel. In case damages resulted from delays caused by force
majeure taking place in Germany or through willful acts by Tractebel, Tractebel
will bear the entire cost of damages. In case the damages result from delays
caused by force majeure in China or through willful acts by the Builder, the
Builder will bear the entire cost of damages. If the Tractebel Performance Bond
is called in part


                                      - 2 -
<PAGE>

or in full, Tractebel shall have the right to obtain from the Builder
reimbursement of the amount paid under the Tractebel Performance Bond that it is
excess of Tractebel's liabilities to the Builder under the contracts between the
Builder and Tractebel and the sharing of liability between the parties shall be
in the proportions set forth above. If the Builder Performance Bond is called in
part or in full, the Builder shall have the right to obtain from Tractebel
reimbursement of the amount paid under the Builder Performance Bond to the
extent such amount is payable under Tractebel liabilities to the Builder under
the contracts between the Builder and Tractebel and the sharing of liability
between the parties shall be in the proportions set forth above.

                  (c) The Refund Guarantee, Builder Performance Bond and
Tractebel Performance Bond shall expire on May 1, 2001. The Builder hereby
commits itself not to undertake any new building orders from other shipowner
which would interfere with the delivery schedule of the five (5) Vessels.

                  (d) The Builder hereby agrees to instruct the United States
Trust Company of New York as Collateral Agent (the "Collateral Agent") under the
Collateral Agency and Intercreditor Agreement to pay a portion of the initial
installment due under the Shipbuilding Contracts for Vessels bearing Hull Nos.
2245 and 2246 directly to Tractebel in an amount equal to US$697,500 for Hull
No. 2245 and US$697,500 for Hull No. 2246; which in each case represents 5.0% of
the contract price payable under the purchase contracts between the Builder and
Tractebel for the respective Vessels. The aforementioned payment shall be made
by the Collateral Agent on the Issue Date as defined in the Collateral Agency
and Intercreditor Agreement.

         3. LAW APPLICABLE The parties hereto agree that the validity,
enforcement and interpretation of this Triparty Agreement and of each Article
and part hereof be governed by and interpreted in accordance with the Laws of
England.

         4. AMENDMENTS No representative of either party shall have authority to
make, and neither party shall be bound by, nor liable for, any statement,
representation, promise or agreement not set forth herein. No changes,
amendments or modifications shall be valid unless reduced to writing and signed
by the parties hereto. In addition the parties hereto further agree that no
changes, amendments or modifications shall be made to the Shipbuilding Contracts
unless such agreement is reduced to writing, signed by the Builder and the Owner
(or its assigns), and consented to by Tractebel.

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

Ladies and Gentlemen:

                  We are counsel to Navigator Gas Transport PLC ("Navigator Gas
Transport"), Navigator Gas (IOM I-A) Limited, Navigator Gas (IOM I-B) Limited,
Navigator Gas (IOM I-C) Limited, Navigator Gas (IOM I-D) Limited and Navigator
Gas (IOM I-E) Limited (the "Owners," and together with Navigator Gas Transport,
the "Registrants") in connection with the registration under the Securities Act
of 1933, as amended (the "Act"), of Navigator Gas Transport First Priority
Exchange Ship Mortgage Notes Due 2007 (the "First Priority Exchange Notes"), and
the Second Priority Exchange Ship Mortgage Notes Due 2007 (the "Second Priority
Exchange Notes", together with the First Priority Exchange Notes, the "Notes"),
and the related preparation and filing of a Registration Statement on Form F-4
(the "Registration Statement").

         The First Priority Exchange Notes are issuable under the Indenture,
dated as of August 1, 1997 (the "First Priority Indenture"), between the
Registrants and United States Trust Company of New York as indenture trustee.
The Second Priority Exchange Notes are issuable under the


<PAGE>



Indenture, dated as of August 1, 1997 (the "Second Priority Indenture," together
with the First Priority Indenture, the "Indentures"), between the Registrants
and The Chase Manhattan Bank Company of New York as indenture trustee. The
Indentures are substantially in the form filed as an Exhibit to the Registration
Statement. This opinion is rendered pursuant to Items 601(5) and (8) of
Regulation S-K promulgated by the Securities and Exchange Commission.

                  In connection with rendering this opinion letter, we have
examined the Indenture contained as an Exhibit to the Registration Statement,
the Registration Statement and such other documents as we have deemed necessary.
As to matters of fact, we have examined and relied upon representations or
certifications of officers of the Registrant or public officials. We have
assumed the authenticity of all documents submitted to us as originals, the
genuineness of all signatures, the legal capacity of natural persons and the
conformity to the originals of all documents submitted to us as copies. We have
assumed that all parties, other than the Registrants, had the corporate power
and authority to enter into and perform all obligations thereunder. As to such
parties, we have also assumed the due authorization by all requisite corporate
action, the due execution and delivery and the validity, binding effect and
enforceability of such documents.

                  In rendering this opinion letter, we express no opinion as to
the laws of any jurisdiction other than the federal laws of the United States
and the laws of the State of New York, nor do we express any opinion on any
issue not expressly addressed below.

                  Based on the foregoing, we are of the opinion that:

                  1. The Indentures have been duly authorized by the Registrants
and are legal and valid obligations of the Registrants, enforceable in
accordance with their terms, except as enforceability may be limited by (a)
bankruptcy, insolvency, liquidation, receivership, moratorium, reorganization or
other similar laws affecting the enforcement of the rights of creditors and (b)
general principles of equity, whether enforcement is sought in a proceeding in
equity or at law.

                  2. When the Notes have been duly executed and authenticated in
accordance with the provisions of the Indentures, and issued as contemplated in
the Registration Statement and the prospectus delivered in connection therewith,
such Notes will be legally and validly issued and outstanding and the holders of
such Notes will be entitled to the benefits of the Indenture.

                  3. The description of federal income tax consequences
appearing under the heading "Material United States Federal Income Tax
Consequences" in the prospectus contained in the Registration Statement, is our
opinion as to material federal income tax consequences of the Exchange Offer.

         We hereby consent to the filing of this opinion letter as an Exhibit to
the Registration Statement, and to the use of our name in the prospectus
included in the Registration Statement under the heading "Legal Matters" and
"Material United States Federal Income Tax


<PAGE>


Consequences", without admitting that we are "experts" within the meaning of the
Act and the rules and regulations thereunder with respect to any part of the
Registration Statement including this Exhibit.


                                            Very truly yours,

                                            THACHER PROFFITT & WOOD

In this opinion, the "Documents" means the documents referred to at paragraphs 1
to 24 inclusive and the "Security Documents" means the documents referred to at
paragraphs 3, 16, 20 and 21.

In arriving at the opinion expressed below, in addition to examining the
Documents, we have examined such other documents as have been revealed by
searches of the Isle of Man Companies Registry and Rolls Office undertaken on 1
August 1997 and updated on 6 August 1997, in respect of each of Holdings, the
Issuer, the Manager and the Owners.


                                        3

In arriving, at our opinion we have assumed:

(A)      the genuineness of all signatures on original documents, the
         correctness of all facts stated in and representations made in the
         documents which we have examined (except as otherwise opined upon
         herein) and the conformity to original documents of all copy documents;

(B)      that each of the parties to the Documents (other than each of Holdings,
         the Issuer, the Manager and the Owners) is duly incorporated, validly
         existing and fully authorised, qualified and empowered under their
         respective constitutions and any applicable laws to carry on business
         and to enter into and perform their respective obligations and exercise
         their respective rights under each of the Documents;

(C)      that each of the parties to the Documents (other than each of Holdings,
         the Issuer, the Manager and the Owners) has taken all corporate and
         other action required to authorise the execution of the Documents and
         the performance of their respective obligations thereunder;

(D)      that there are no provisions of the laws of any jurisdiction outside
         the Isle of Man or any agreement to which any of the parties to the
         Documents is a party which would be contravened by such execution or
         delivery and that, insofar as any obligation under the Documents falls
         to be performed in any jurisdiction outside the Isle of Man, its
         performance will not be unlawful by virtue of the laws of that
         jurisdiction;

(E)      that the Documents, once they have been validly executed and delivered,
         will not differ to any material extent from the copy drafts thereof
         which have been submitted to us and which we have examined in giving
         our opinion;

(F)      that the Documents (with the exception of each Issue of One Debenture
         which is subject to Isle of Man law) will, when validly executed and
         delivered, be valid and legally binding in accordance with their terms
         under the laws by which they are expressed to be governed;

(G)      the accuracy and currency of the records and filing systems maintained
         at the public offices where we have searched or inquired or have caused
         searches or inquiries to be conducted;

(H)      that all necessary consents or approvals of, and all necessary
         registrations or other action by or with, any regulatory authority or
         any other person or entity outside the Isle of Man have been or will be
         obtained, performed or taken in relation to the execution, delivery and
         performance of each of the Documents by each of the parties thereto;

(I)      that all appropriate notices of and consents to assignment required to
         be given or which it is desirable to be given in connection with any of
         the Documents are, in fact given in timely fashion;


                                        4

<PAGE>



(J)      that entering into the Documents and performing the obligations which
         each of Holdings, the Issuer, the Manager and the Owners undertakes is
         to its respective commercial benefit;

(K)      that each of Holdings, the Issuer and the Owners has acquired tax
         exempt status in terms of the Income Tax (Exempt Companies) Act 1984
         (an Act of Tynwald) and will maintain such tax status and will not do
         anything to prejudice such tax status during the currency of the
         transaction envisaged by the Documents. We confirm that appropriate
         steps have been taken to obtain such tax status and that we have no
         reason to believe that such tax status will not be granted; the process
         of obtaining such tax status is administrative and not one subject to
         the exercise of discretion;

(L)      that the Manager is not and will not be resident in the Isle of Man for
         tax purposes during the currency of the transaction envisaged by the
         Documents.

Based on and subject to the foregoing and subject to the further reservations
and qualifications set out below, we are of the opinion that:

(i)      each of Holdings, the Issuer, the Manager and the Owners is duly
         incorporated in the Isle of Man, is validly existing as a company in
         good standing under the laws of the Isle of Man and has the corporate
         power and authority to own its property and to conduct its business as
         described in the Offering Circular;

(ii)     each of Holdings, the Issuer, the Manager and the Owners has taken all
         corporate and other action required to authorise the execution of the
         Documents and the performance of their respective obligations
         thereunder (as applicable) to the extent a party thereto;

(iii)    shares in Holdings conform to the description thereof in the Offering
         Circular and have been duly authorised and validly allotted to such
         persons and for such consideration as is described in the Offering
         Circular;

(iv)     all the shares issued by the Issuer and the Owners have respectively

         been duly authorised and validly issued as fully paid up. To our
         knowledge, the issued shares of the Issuer and the Owners are legally
         owned by Holdings or the Issuer, as the case may be, free and clear of
         any pledge, lien, security interest, charge, claim, equity or
         encumbrance of any kind, except for one ordinary share in the Issuer
         which is beneficially owned by Holdings but which is legally owned by
         Mr. Edward Cain of 1519 Athol Street, Douglas, Isle of Man, IM1 1LB,
         and except for the security interests created by or pursuant to the
         Security Documents, and subject thereto, there are no outstanding
         rights, warrants or options to acquire, or instruments convertible
         into or exchangeable for, shares in the Issuer or any of the Owners;

(v)      the First Priority Notes, and the Second Priority Notes and the
         Warrants comprising the Units have been duly authorised for issue,
         execution and delivery by the Issuer and Holdings, (as applicable), and
         conform to the descriptions thereof contained in the Offering Circular;

                                        5

<PAGE>



(vi)     each of the Documents has been duly authorised, executed and delivered
         by Holdings, the Issuer, the Manager and each of the Owners (as
         applicable) to the extent a party thereto, and the Documents constitute
         valid and legally binding obligations of Holdings, the Issuer, the
         Manager or each of the Owners to the extent a party thereto,
         enforceable against such of Holdings, the Issuer, the Manager or such
         Owner in accordance with its terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganisation, moratorium or similar laws of
         general applicability affecting creditors' rights and to general equity
         principles;

(vii)    the information disclosed in the Offering Circular, so far as it
         relates to matters of Isle of Man law, fairly summarises the said
         matters of Isle of Man law as at the date of the said Offering
         Circular;

(viii)   no withholding taxes will be imposed on payments of principal, interest
         or premium (if any) thereon with respect to the First Priority Notes
         or the Second Priority Notes and the holders of First Priority Notes
         or Second Priority Notes will not be subject to any income taxes
         imposed by the Isle of Man solely as a result of owning the First
         Priority Notes or the Second Priority Notes. In addition, the holders
         of the Warrants will not be subject to any income or withholding taxes
         imposed by the Isle of Man solely as a result of owning the Warrants,
         exercising the Warrants to purchase ordinary shares in the share
         capital of Holdings or owning ordinary shares in the share capital of
         Holdings;

(ix)     no consent, approval, authorisation, permission or other order of any 
         court, regulatory body, administrative agency or other governmental
         body of the Isle of Man is required for the offering and sale of the
         First Priority Notes and the Units or for the execution, delivery and
         performance of any of the Documents (including the exercise by the
         Collateral Agent of the rights and remedies granted to it under any of
         the Security Documents, subject to the filing requirements pursuant to
         paragraph (xvi) below) by the respective parties thereto, other than
         the permission of the Treasury of the Isle of Man Government pursuant
         to Section 2(2)(d) of the Prevention of Fraud (Investments) Act 1968
         (an Act of Tynwald);

(x)      the security interests created by the Collateral Agency and 
         Intercreditor Agreement (being a document governed by the laws of the
         State of New York) do not require any action to be taken under or
         pursuant to the laws of the Isle of Man in order to create or perfect
         such security interests or to permit the Collateral Agent to enforce
         its rights under the Collateral Agency and Intercreditor Agreement
         creating the same, other than (i) the delivery by Holdings of the
         share certificates of the Issuer to the Collateral Agent on the
         Closing Date, (ii) the delivery by the Issuer of the share
         certificates of the Owners to the Collateral Agent on the Closing
         Date, (iii) the delivery by the Owners of an Inter-Company Note to the
         Issuer and (iv) the making of filings referred to in paragraph (xvi)
         below;

(xi)     the choice of the law of the State of New York to govern the Documents
         governed by New York law, constitutes a valid choice of law insofar as
         the law of the Isle of Man is concerned. The submission by Holdings,
         the Issuer and the Owners to the nonexclusive jurisdiction of

                                        6

<PAGE>



         any Federal or State court in the Borough of Manhattan, The City of New
         York in respect of any of the Documents governed by New York law to
         which they are respectively a party is a valid submission insofar as
         the law of the Isle of Man is concerned; in this regard we note that
         Cambridge Partners, L.L.C. has accepted its appointment by Holdings,
         the Issuer and the Owners as their agent to accept service of process
         in the United States of America under the Documents (as applicable);

(xii)    the issue of One Debenture to which each of the Owners is a party
         creates, for the benefit of the Collateral Agent as secured party, a
         valid security interest in assets of such owner and the proceeds
         thereof, which security interest will, upon registration in accordance
         with paragraph (j) of the reservations section of this letter below
         rank in priority to other charges created by such Owner of which we are
         aware, except for those interests which by operation of law, will take
         priority;

(xiii)   security interests created by the Security Documents (with the
         exception of floating charge elements of the Issue of One Debenture and
         any other Security Document) are specific and therefore upon
         registration in accordance with paragraph (j) of the reservations
         section of this letter below will rank in priority to other security
         interests created over the assets which are the substance of those
         Security Documents except for those interests which, by operation of
         law, will take priority;

(xiv)    the Issue of One Debenture and other Security Documents (as applicable)
         constitute, in respect of floating charge elements thereof, a first
         ranking perfected floating charge (but not a fixed charge); recoveries
         under the floating charge element may be subject to certain
         preferential creditors;

(xv)     in a suit on the merits brought before an isle of Man court, an Isle of
         Man court may, if so requested and at its discretion, give effect to an
         agreement between the parties as to a judgment currency other than
         pounds sterling;

(xvi)    no filing with any governmental authority or regulatory body of the
         Is1e of Man is required for the offering and sale of the First Priority
         Notes and the Units or for the execution, delivery and performance of
         any of the Documents, except as stipulated at paragraphs (j) and (k) of
         the reservations section of this letter below;

(xvii)   any final and conclusive money judgment (whether in sterling, or
         otherwise) obtained in a properly constituted court of the United
         States of America will be recognized and enforceable in any proceedings
         before the courts of the Isle of Man without reexamination or
         re-litigation on any matter which shall be the subject of that
         judgment;

(xviii)  none of Holdings, the Issuer, the Manager or the Owners nor any of
         their respective properties has any immunity from jurisdiction of any
         court or from any legal process under the laws of the Isle of Man;

                                        7

<PAGE>



(xix)    the execution, delivery and performance by Holdings, the Issuer, the
         Manager and the Owners of the Documents (to the extent a party
         thereto), does not conflict with their respective memorandum and
         articles of association;

(xx)     on the principle laid down in Saloman v. A Saloman and Co. Limited
         [1897] AC22, as applied in the recent case of Poly Peck International
         Finance Limited [1996] BCC486, it is our opinion that, if any of
         Holdings, the Issuer or the Owners was wound up, the courts of the Isle
         of Man would not order substantive consolidation of the assets and
         liabilities of the relevant company with those of third parties or with
         those of its shareholders The courts may, however, lift the corporate
         veil where a company is a facade as an unconscionable attempt to avoid
         existing obligations or to practice some deception; and

(xxi)    the granting of the security interests by the Owners and Holdings would
         not be subject to review under relevant fraudulent conveyance statutes
         and other applicable insolvency laws of the Isle of Man in a
         bankruptcy or other proceeding involving one or more of the Owners and
         Holdings. Under the said fraudulent conveyance statutes and other
         applicable insolvency laws of the Isle of Man, if a court were to find
         that, with respect to any Owner or Holdings, at the time the security
         interests were granted (the "Transfer"), it (a) made such Transfer
         with actual intent to prefer or defraud any present or future
         creditor, (b) received less than reasonably equivalent value of fair
         consideration for the Transfer or (c) intended to incur, or believed
         that it would incur, debts beyond its ability to pay as they matured
         (as the foregoing terms are defined in or interpreted under the
         relevant laws) such court could avoid the Transfer in whole or in
         part. To the extent that a Transfer by any Owner or Holdings exceeds
         the consideration received by it, the determination of whether the
         Transfer in question is a fraudulent conveyance depends on (1) whether
         the Transfer so exceeds the value and benefit received by such Owner
         or Holdings that, at least to the extent of such excess, the Owner of
         Holdings did not receive reasonably equivalent value or fair
         consideration for the Transfer, and, if so, then (2) whether following
         the valuation of the assets and liabilities of such Owner or Holdings,
         it is determined that such Owner or Holdings is or has been rendered
         insolvent.

The opinions expressed above are given subject to the following reservations and
qualifications:

(a)      except as otherwise set forth in paragraph (xxi) above, enforcement of
         any of the Documents may be limited by bankruptcy, insolvency,
         liquidation, reorganisation, court schemes, moratoriums, the doctrine
         of frustration and laws relating to or affecting the rights of
         creditors generally;

(b)      enforcement of any of the Documents may be limited by general
         principles of equity and, in particular, equitable remedies are
         available only at the discretion of the Isle of Man courts and are not
         available where damages are considered to be an adequate remedy;

(c)      claims may be or become time barred in the Isle of Man under the
         Limitation Acts 1984 and 1988 (Acts of Tynwald) or become subject to a

(d)      under Isle of Man law the terms of an agreement under hand may be
         varied by oral or written agreement of the parties;

(e)      a foreign judgment would not be enforced by an Isle of Man court
         without a re-trial or re-examination of the matters thereby adjudicated
         upon if a judgment were obtained by fraud or in a manner contrary to
         natural justice or if the enforcement thereof were contrary to Isle of
         Man public policy and such enforcement may also be withheld if the
         relevant judgment were not a final and conclusive money judgment being
         both unrelated to taxation and free of conflict with any other judgment
         in the same cause of action;

(f)      The Protection of Trading Interests Act 1980 (an Act of Parliament
         extended to the Isle of Man by Order in Council) prohibits the
         enforcement in the Isle of Man of any judgment for multiple damages
         that is to say a judgment for an amount arrived at by doubling,
         trebling or otherwise multiplying a sum assessed as compensation for
         the loss or damage sustained by the judgment creditor;

(g)      provisions relating to set-off contained in any of the Documents will
         only be enforceable in a liquidation of a company insofar as they do
         not purport to contract out of the mandatory set-off rules imposed by
         the Bankruptcy Code 1892;

(h)      if proceedings are commenced in the Isle of Man courts any provision in
         any of the Documents to the effect that calculations and/or
         certifications will be conclusive and binding will not be effective in
         Isle of Man law if such calculations and/or certifications are
         fraudulent or erroneous on their face and will not necessarily prevent
         judicial inquiry into the merits of any claim respecting any such
         calculation or certification;

(i)      if proceedings are commenced in the Isle of Man courts, where in any of
         the Documents a party is vested with a discretion or may determine a
         matter in its opinion, the law of the Isle of Man may require that such
         discretion is exercised reasonably or that such opinion is based on
         reasonable grounds;

(j)      the Security Documents should be lodged for filing at the Companies
         Registry in the Isle of Man pursuant to Section 79 of the Companies Act
         1931 (as amended) within one month from their respective dates of
         creation. Failure to do so will, in the event that any of the Security
         Documents are of a type referred to in Section 79 of that Act, render
         them void against a liquidator or creditor of the relevant company and
         priority over other creditors will be lost. We confirm that we have
         been instructed to attend to the said filing of the Security Documents;

(k)      copies of the Offering Circular, together with copies of certain other
         documents, must be registered with the Registrar of Companies in the
         Isle of Man pursuant to Section 38 of the Companies Act 1931 (as
         amended) (an Act of Tynwald) before the Offering Circular is issued by
         Holdings and the Issuer;

                                        9

(l)      provisions as to severability in any of the Documents may not be
         binding and the question of whether or not provisions relating to
         invalidity may be severed from other provisions in order to save such
         other provisions would be determined by the Isle of Man courts at their
         discretion:

(m)      no opinion is expressed as to whether the Isle of Man courts would give
         effect to any currency indemnities contained in the Documents;

(n)      the validity under Isle of Man law of any provision which purports to
         impose an obligation on one party to meet the costs of another on a
         full indemnity basis will be subject to the right of the Isle of Man
         courts to override such provision and award costs on a less than full
         indemnity basis;

(o)      we express no opinion as to the validity or the binding effect of any
         provision which provides for the payment of interest on overdue
         amounts. An Isle of Man court would not give effect to such provisions
         if it could be established that the amount expressed as being payable
         was such that the provision was in the nature of a penalty; that is to
         say a requirement for a stipulated sum to be paid irrespective of; or
         necessarily greater than, the loss likely to be sustained:

(p)      the Isle of Man courts may stay proceedings if concurrent proceedings
         are being brought elsewhere;

(q)      in proceedings before the Isle of Man courts any indemnities and
         provisions to pay increased costs contained in the Documents may not be
         enforced to the extent that such indemnities and provisions would
         amount to compensation for any economic loss which was outside the
         reasonable contemplation of the parties at the time of execution of the
         Documents and to the extent that the clauses purport to oust the
         jurisdiction of the Isle of Man court;

(r)      any provisions of the Documents which purport to permit retention of
         security after discharge of the liabilities secured thereby may not be
         effective as a matter of Isle of Man law;

(s)      the stock pledge as an equitable charge is a weaker form of security
         than a legal charge; we have assumed (with your agreement) that you are
         aware of this fact and the facts giving rise to it;

(t)      no opinion is expressed (i) as to whether the Isle of Man courts would
         construe any of the Documents without giving effect to principles of
         conflict of laws; or (ii) as to whether the obligations of each Owner
         under the Issue of One Debenture may be discharged, released,
         prejudiced or otherwise affected by any act, omission or circumstance
         which, but for provisions contained in the Issue of One Debenture,
         might so operate or otherwise release or discharge such Owner from the
         obligations set out herein; and


                                       10

(u)      this opinion addresses matters of law not fact and is confined entirely
         to Isle of Man law.

This opinion may only be relied upon by you and may not be disclosed or relied
upon by any other person without our prior written consent. Notwithstanding the
foregoing, this opinion may be relied upon by Thacher Proffitt & Wood and
Cravath, Swaine & Moore, in connection with the delivery of their opinions to
you pursuant to the Documents.

                          (i) the amounts set forth on Schedules 2 and 3 hereto
                  calculated as of the first day of the calendar month in which
                  the Date of Rejection occurs,

                          (ii) an amount equal to the product of (x) the
                  difference between (1) the amount set forth on Schedule 2
                  hereto calculated as of the first day of the calendar month
                  immediately succeeding the month in which the Date of
                  Rejection occurs and (2) the amount set forth on Schedule 2
                  hereto as of the first day of the month in which the Date of
                  Rejection occurs and (y) a fraction the numerator of which is
                  the numeric day of the month of the Date of Rejection and the
                  denominator of which is 30, and

                          (iii) an amount equal to the product of (x) the
                  difference between (1) the amount set forth on Schedule 3

If the amount as calculated above is not paid on the Date of Rejection there
shall be added to such amount interest at the rate of ten percent (10%) per
annum from and including the Date of Rejection to but not including the date

discharge all obligations, duties, and liabilities of each of the parties hereto
to the other under this Contract. Any and all refunds made to the BUYER under
this Article II, Section 7 shall be made in United States Dollars. Throughout
this Contract, whenever interest is due on any amounts to be paid or refunded by

                                   ARTICLE III

        The Contract Price of the VESSEL as provided for in Schedule 1 shall be
subject to adjustments as hereinafter set forth. It is hereby understood by both
parties that any reduction of the Contract Price is by way of liquidated damages
and not by way of penalty.

1.      DELIVERY

        (a)       Delayed Delivery Price Adjustment:

                          (i) For purposes of this Contract the Original
                  Delivery Date for the Vessel shall mean the date set forth in
                  Article VII, Section (1) below.

                          (ii) If the Delivery is not made on the Original
                  Delivery Date (subject to a Permissible Delay as defined
                  below), the SELLER shall pay the BUYER, as liquidated damages
                  (not as penalty), the amount of $10,000 for each calendar day
                  for the first ninety (90) calendar days of delay beyond the
                  Extended Delivery Date (as hereinafter defined) and the amount
                  of $13,500 for each calendar day of delay thereafter up to and
                  including the 210th day from the Original Delivery Date
                  ("Original Delay

                  Period"). Liquidated damages calculated with respect to the
                  Original Delay Period shall be recovered by the BUYER through
                  a reduction in the Fifth Installment payable by the BUYER to
                  the SELLER in an amount equal to such Liquidated Damages.

                          (iii) If delivery of the VESSEL is delayed for any
                  reason beyond the Original Delay Period, the Builder may elect
                  to further postpone delivery of the Vessel beyond the Original
                  Delay Period until March 31, 2001 provided SELLER pays
                  liquidated damages monthly in advance to the BUYER at the rate
                  of US$18,000 per day from the end of the Original Delay Period
                  to a date which is 6 months thereafter (the "First Penalty
                  Date"), and US$20,000 per day from the First Penalty Date to
                  the date which is 6 months thereafter (the "Second Penalty
                  Date"), and US$22,000 per day from the Second Penalty Date
                  until March 31, 2001. If the SELLER fails to make any
                  liquidated damages payment, BUYER, in its sole discretion, may
                  either (i) reject the VESSEL or (ii) waive its right to
                  receive the payment of liquidated damages and further reduce
                  the Contract Price for the VESSEL by an amount equal to the
                  liquidated damages which would have been payable.
                  Notwithstanding any other provision contained in this Contract
                  to the contrary, this Contract shall be deemed rescinded on
                  April 1, 2001 and the Buyer shall be entitled to receive the
                  amounts set forth in Article II, Section 7(a) above.

                          Any waiver by the BUYER of its right to receive
                  liquidated damages monthly in advance is not a waiver of the
                  BUYER's right to (a) demand payment of such liquidated damages
                  at a later date, (b) demand monthly advances as to Liquidated
                  Damages for any subsequent months of delay or (c) reject the
                  VESSEL at such later date if liquidated damages are not paid
                  upon demand. The liquidated damages calculated pursuant to
                  this paragraph are in addition to the reduction in the fifth
                  installment of the Contract Price as calculated pursuant to
                  (ii) above for the Original Delay Period.

                          (iv) In the event that the BUYER elects to reject the
                  VESSEL as allowed under this Article III, Section 1(a), the
                  SELLER shall immediately repay to the BUYER the amounts set
                  forth in Article II, Section 7, whereupon this Contract shall
                  terminate and such payment shall forthwith discharge all
                  obligations, duties and liabilities of each party hereto to
                  the other under this Contract.

                  the VESSEL shall not be deemed delayed and the Contract Price
                  shall not be reduced when and if the Original Delivery Date of

                  (2) Article VIII, and (3) any delay caused by any action or
                  inaction on the part of SELLER; provided such Permissible
                  Delay shall be subject to the following provisions:

                                   (A) The maximum Permissible Delay for the
                          Vessel and each Sister Vessel shall be as follows:

                                            (i)     Hull No. 2245 - 60 days

                                            (iv)    Hull No. 2248 - 30 days
                                            (v)     Hull No. 2249 - 30 days

                                   (B) For purposes of this Contract the
                          Extended Delivery Date for a Vessel shall mean the
                          Original Delivery Date plus the Permissible Delay for
                          such Vessel,

                                   (C)  The aggregated Permissible Delay for the
                          Vessel and the Sister Vessels shall not exceed 150 
                          days, and

                                   (D) Subject to the limitations set forth in
                          (A) above, SELLER shall have the right in its sole
                          discretion to designate either the Vessel or any
                          Sister Vessel as to which Vessel will be subject to a
                          Permissible Delay.

        (b)       Early Delivery Price Adjustment:

                          If the SELLER notifies the BUYER by facsimile that the
                  delivery of the VESSEL shall be made earlier than the Original
                  Delivery Date and such notification is given not less than two
                  (2) months prior to the newly planned delivery date, a certain
                  amount of bonus shall be given by the BUYER to the SELLER as
                  follows:

                          In the event that the delivery shall be made earlier
                  than the Original Delivery Date and notice is properly given,
                  then a bonus shall be added to the Contract Price at a rate of
                  United States Dollars Thirteen Thousand (US$13,000) per day
                  for each full day earlier than the Original Delivery Date.

                          The total increase of the Contract Price for the
                  earlier delivery shall be added to the fifth installment of
                  the Contract Price.

2.      INSUFFICIENT SPEED

        (a) The Contract Price of the VESSEL shall not be affected nor changed
by reason of the actual speed (as determined by the Trial Run after correction

this Contract.

        (b) However, commencing with a deficiency of three-tenths (3/10) of one

to the Specifications) below the guaranteed speed as specified in Section 4,
Article I of this Contract, the Contract Price shall be reduced as follows:

                                    ARTICLE V
                        MODIFICATION, CHANGES AND EXTRAS

1.      HOW EFFECTED

        The Specifications in accordance with which the VESSEL is constructed,
may be modified and/or changed at any time hereafter by written agreement of the
parties hereto, provided that such modifications and/or changes or an
accumulation thereof will not, in the BUILDER's reasonable judgment, adversely
affect the BUILDER's other commitments and provided further that the BUYER shall
assent to adjustment of the Contract Price, time of delivery of the VESSEL and
other terms of this Contract, if any, as hereinafter provided. Subject to the
above, the SELLER hereby agree to exert their best efforts to accommodate such
reasonable requests by the BUYER so that the said changes and/or modifications
may be made at a reasonable cost and within the shortest period of time which is
reasonable and possible. Any such agreement for modifications and/or changes
shall include an agreement as to the increase or decrease, if any, in the
Contract Price of the VESSEL together with an agreement as to any extension or
reduction in the time of delivery, providing to the SELLER additional securities
satisfactory to the SELLER, or any other alterations in this Contract, or the
Specifications occasioned by such modifications and/or changes. The
aforementioned agreement to modify and/or to change the Specifications may be
effected by an exchange of duly authenticated letters, telex and telefaxes,
manifesting such agreement. The letters, telexes as well as telefaxes exchanged
by the parties hereto pursuant to the foregoing shall constitute an amendment of
the Specifications under which the VESSEL shall be built, and such letters,
telexes and telefaxes shall be deemed to be incorporated into this Contract and
the Specifications by reference and

made a part hereof. Upon consummation of the agreement to modify and/or to
change the Specifications, the SELLER shall alter the construction of the VESSEL
in accordance therewith, including any additions to, or deductions from, the
work to be performed in connection with such construction. If due to whatever
reasons, the parties hereto shall fail to agree on the adjustment of the
Contract Price or extension of time of delivery or providing additional security
to the SELLER or modification of any terms of this Contract which are
necessitated by such modifications and/or changes, then the SELLER shall have no
obligation to comply with the BUYER's request for any modification and/or
changes.

2.      CHANGES IN RULES AND REGULATIONS

        (a) If, after the Effective Date, any requirements as to the rules and
regulations as specified in this Contract and the Specifications to which the
construction of the VESSEL is required to conform, are altered or changed by the
Classification Society or the other regulatory bodies authorized to make such
alterations or changes, the SELLER and/or the BUYER, upon receipt of the notice
thereof, shall transmit such information in full to each other in writing,
whereupon within twenty one (21) days after receipt of the said notice by the
BUYER from the SELLER or vice versa, the BUYER shall instruct the SELLER in
writing as to the alterations or changes, if any, to be made in the VESSEL which
the BUYER, in its sole discretion, shall decide. The SELLER shall promptly
comply with such alterations or changes, if any in the construction of the
VESSEL, provided that the BUYER shall first agree:

                  (i) As to any increase or decrease in the guaranteed
        deadweight and/or cargo tank capacity and for speed of the VESSEL, if
        such compliance results in increased or reduced deadweight and/or cargo
        tank capacity and speed; and/or

                  (ii) As to any other alterations in the terms of this Contract
        or of Specifications or both, if such compliance makes such alterations
        of the terms necessary.

        Agreement as to such alterations or changes under this Paragraph shall
be made in the same manner as provided above for modifications and/or changes of
the Specifications and/or Plans.

        (b)       If, due to whatever reasons, the parties shall fail to agree
on the increase or decrease of the guaranteed speed, deadweight and cargo tank
capacity,

be entitled to proceed with the construction of the VESSEL in accordance with,
and the BUYER shall continue to be bound by, the terms of this Contract and
Specifications without making any such alterations or changes.

        (c) The BUYER and the SELLER hereby agree to make best efforts to avoid
the application and/or minimize the effect of any change in the rules and
regulations of the Classification Society as to the Specifications. If the BUYER
and the SELLER are unsuccessful in avoiding the application of such change in
rules and regulations, then the SELLER shall effect any modifications and/or
changes in Specifications without adjustment to the Contract Price and the BUYER
shall grant to the SELLER the right to extend the Delivery Date (if necessary)
for a maximum period of up to twelve (12) days.

3.      SUBSTITUTION OF MATERIALS AND/OR EQUIPMENT

        In the event that any of the materials and/or equipment required by the
Specifications or otherwise under this Contract for the construction of the
VESSEL cannot be procured in time to effect delivery of the VESSEL, the SELLER
may, provided the SELLER shall provide adequate evidence and the BUYER so agrees
in writing, supply other materials and/or equipment of the equivalent quality,
capable of meeting the requirements of the Classification Society and of the
rules, regulations, requirements and recommendations with which the construction
of the VESSEL must comply.

4.      BUYER'S SUPPLIED ITEMS

        The BUYER shall deliver to the SELLER at its shipyard the items as
specified in the Specifications which the BUYER shall supply for its own account
(the "BUYER's Supplies") by the time designated by the SELLER.

        The delay in the delivery or the failure to deliver by the BUYER of any
BUYER's Supplies within the time specified shall not extend the Delivery Date.

        However, if the delay in delivery of the BUYER's Supplies should exceed
fifteen (15) days, the SELLER shall be entitled to proceed with construction of
the VESSEL without installation of such items in or onto the VESSEL and the
BUYER shall accept the VESSEL so completed.

        The BUILDER shall be responsible for storing and handling of the BUYER's
Supplies as specified in the Specifications after delivery to the BUILDER and
shall install them on board the VESSEL at the BUILDER's expenses.

        Upon arrival of such shipment of the BUYER's Supplies, both parties
shall undertake an joint unpacking inspection. If any damaged BUYER's supplies
are found to be unsuitable for installation, the BUILDER shall be entitled to
refuse to accept the BUYER's Supplies.

                                   ARTICLE VI
                                     TRIALS

1.      NOTICE

        The BUYER and the Supervisor shall receive from the SELLER at least
thirty (30) days notice in advance and seven (7) days definite notice in advance
in writing by telex or telefax, of the time and place of the VESSEL's sea trial
as described in the Specifications (hereinafter referred to as "the Trial Run")
and the BUYER and the Supervisor shall promptly acknowledge receipt of such
notice. The BUYER's representatives and/or the Supervisor shall be on board the
VESSEL to witness such Trial Run, and to check upon the performance of the
VESSEL during the same. Failure of the BUYER's representatives to be present at
the Trial Run of the VESSEL, after due notice to the BUYER and the Supervisor as
provided above, shall have the effect to extend the date for delivery of the
VESSEL by the period of delay caused by such failure to be present. However, if
the Trial Run is delayed more than five (5) days by reason of the failure of the
BUYER's representatives to be present after receipt of due notice as provided
above (other than due to the failure by the BUYER's representative to obtain a
visa to enter China), then in such event, the BUYER shall be deemed to have
waived its right to have its representatives on board the VESSEL during the
Trial Run, and the BUILDER may conduct such Trial Run without the BUYER's
representatives being present, and in such case the BUYER shall be obliged to
accept the VESSEL on the basis of a certificate jointly signed by the BUILDER
and the Classification Society certifying that the VESSEL, after Trial Run
subject to minor alterations and corrections as provided in this Article, if
any, is found to conform to the Contract and Specifications and is satisfactory
in all respects. The SELLER hereby warrants that the necessary visa for the
BUYER's representatives to enter China will be issued in order on demand and
without delay otherwise the Trial Run shall be postponed until the BUYER's
representatives have arrived at the BUILDER's Shipyard. However, should the
nationalities and other personal particulars of the BUYER's representatives be
not acceptable to the SELLER in accordance with its best understanding of the
relevant

                                      -22-

rules, regulations and/or Laws of the People's Republic of China then
prevailing, then the SELLER shall so notify the BUYER and the BUYER shall
endeavor to effect the replacement of all or any of such representatives. The
Delivery Date as stipulated in Article VII hereof shall not be extended by any
delays caused by the BUYER's replacement of its representatives pursuant to the
SELLER's request. In the event of unfavorable weather on the date scheduled for
the Trial Run, the same shall take place on the first available day thereafter
that the weather conditions permit. The parties hereto recognize that the
weather conditions in Chinese waters in which the Trial Run is to take place are
such that great changes in weather may arise momentarily and without warning
and, therefore, it is agreed that if during the Trial Run of the VESSEL, the
weather should suddenly become unfavorable, as would have precluded the
continuance of the Trial Run, the Trial Run of the VESSEL shall be discontinued
and postponed until the first favorable day next following, unless the BUYER
assents in writing by telex or telefax of its acceptance of the VESSEL on the
basis of the Trial Run made prior to such sudden change in weather conditions.
In the event that the Trial Run is postponed because of unfavorable weather
conditions, the Delivery Date shall not be extended other than pursuant to
Article VIII hereof.

2.      HOW CONDUCTED

        (a) All expenses in connection with Trial Run of the VESSEL are to be
for the account of the BUILDER, who, during the Trial Run and when subjecting
the VESSEL to Trial Run, is to provide, at its own expense, the necessary crew
to comply with conditions of safe navigation. The Trial Run shall be conducted
in the manner prescribed in the Specifications and shall prove fulfillment of
the performance required for the Trial Run as set forth in the Specifications.

        The course of Trial Run shall be determined by the BUILDER and shall be
conducted within the trial waters equipped with speed measuring facilities.

        (b) The BUILDER shall provide the VESSEL with the required quantities of
water and fuel oil with exception of lubrication oil, hydraulic oil and greases
which shall be supplied by the BUYER according to the BUILDER's schedule which
shall be forwarded to the BUYER by the BUILDER for the conduct of the Trial Run
or Trial Runs as prescribed in the Specifications. The fuel oil supplied by the
SELLER, and lubricating oil, hydraulic oil and greases supplied by the BUYER
shall be in accordance with the applicable engine Specifications, and the cost
of the quantities of water, fuel oil, lubricating oil, hydraulic oil and greases

BUYER shall pay to the SELLER the reasonable mooring charge of the VESSEL.

6.      TENDER OF THE VESSEL

Supplier. The Supplier shall give qualified guidance, instruction and
consultations with regard to the gas trial, all of which shall be arranged by
the SELLER under the terms of its contract with the Supplier. The SELLER shall
at its own expense dispatch its representative(s) to attend such gas trial as
witness. The BUYER shall give the SELLER twenty (20) days advance notice in
connection with the time and place for such trial. The gas trial shall be made
latest forty-five (45) days after delivery of the VESSEL (unless the trial must

        (e) Should the Gas Plant not be in conformity with this Contract and the
Specifications, the SELLER shall remedy any such non-conformity to the
satisfaction of the BUYER, the Classification Society and any other relevant
authority. After the remedial works are completed the SELLER shall arrange to
re-run the gas trial to the extent which will be necessary to demonstrate that
the rectified part of the Gas Plant is then in conformity with this contract and
the Specifications and the proper functioning of the Gas Plant as a whole is
secured.

        (f) All direct costs and expenses of remedying the non-conformity and
re-running the gas trial (including provision of suitable product, utilities and
consumables) shall be for the account of the SELLER.

        (g) If delays are incurred relating to the use of the VESSEL, caused by
an unsuccessful gas trial, remedial works and retrials for which the SELLER is
responsible, with the consequence that the classification certificate has not
been issued, will exceed more than twenty (20) days as from the commencement of
the Gas Trials, the SELLER shall, notwithstanding the provisions contained in
Article IX Section 2 and Section 4, pay to the BUYER as liquidated damages
United States Dollars Ten Thousand (US$10,000) for each day of such excess delay

                    DELAYS AND EXTENSION OF TIME FOR DELIVERY

1.      CAUSE OF DELAY

        If, at any time before actual Delivery, either the construction of the
VESSEL, or any performance required hereunder as a prerequisite of delivery of
the VESSEL, is delayed due to war, blockade, revolution, insurrection,
mobilization, civil commotions, riots, strikes, sabotage, lockouts, local
temperature higher than 35 degree centigrade, Acts of God or the public enemy,
plague or other epidemics, quarantines, prolonged failure or restriction of
electric current from an outside source, freight embargoes, if

any, earthquakes, tidal waves, typhoons, hurricanes, storms or other causes
beyond the control of the BUILDER or of its sub-contractors, as the case may be,
or by force majeure of any description, whether of the nature indicated by the
forgoing or not, or by destruction of the BUILDER or works of the BUILDER or its
sub-contractors, or of the VESSEL or any part thereof, by fire, flood, or other
causes beyond the control of the SELLER or its sub-contractors as the case may
be, then, in the event of delay due to the happening of any of the
aforementioned contingencies, the SELLER shall not be liable for such delay and
the time for delivery of the VESSEL under this Contract shall be extended
without any reduction in the Contract Price subject nevertheless to (i) the
provisions of Section 1(a) of Article III as to reduction in Contract Price,
(ii) the BUYER's right of termination under Section 1(a) of Article III and
(iii) all relevant provisions of this Contract which authorize and permit
extension of the time of delivery of the VESSEL.

2.      NOTICE OF DELAY

        Within fourteen (14) days from the date of commencement of any delay on
account of which the SELLER claims that it is entitled under this Contract to an
extension of the time for delivery of the VESSEL, the SELLER shall advise the
BUYER in writing by telex or telefax of the date such delay commenced, and
reasons therefor.

        Likewise within fourteen (14) days after such delay ends, the SELLER
shall advise the BUYER in writing by telex or telefax of the date such delay
ended, and also shall specify the maximum period of the time by which the date
for delivery of the VESSEL is extended by reason of such delay. Failure of the
BUYER to acknowledge the SELLER's notification of any claim for extension of the
Delivery Date within fourteen (14 ) days after receipt by the BUYER of such
notification, shall be deemed to be a waiver by the BUYER of its right to object
to such extension.

                                   ARTICLE IX
                               WARRANTY OF QUALITY

1.      GUARANTEE OF MATERIAL AND WORKMANSHIP

        The SELLER, for a period of twelve (12) months following delivery to the
BUYER of the VESSEL, guarantees the VESSEL, her hull and machinery and all parts
and equipment thereof that are manufactured or furnished or supplied by the
SELLER and/or its sub-contractors under this Contract including material,
equipment (however excluding any parts for the VESSEL which have been supplied
by or on behalf of the BUYER) against all defects which are due to defective
materials, and/or poor workmanship or failure to construct in conformity with
the Specifications.

2.      NOTICE OF DEFECTS

        The BUYER shall notify the SELLER in writing by telex or telefax, as
promptly as possible, after discovery of any defect or deviations for which a
claim is made under this guarantee. The BUYER's written notice shall describe
the nature of the defect and the extent of the damage caused thereby. The SELLER
shall have no obligation under this guarantee for any defects discovered prior
to the expiry date of the guarantee, unless notice of such defects is received
by the SELLER not later than thirty (30) days after such expiry date. Telexed or
telefaxed advice with brief details explaining the nature of such defect and
extent of damage within thirty (30) days after such expiry date and that a claim
is forthcoming will be sufficient to comply with the requirements as to time.

3.      REMEDY OF DEFECTS

        The SELLER shall remedy at its expense any defect, against which the
VESSEL or any part of the equipment thereof is guaranteed under this Article by
making all necessary repairs and/or replacement. Such repairs and/or replacement
will be made by the SELLER.

        However, if it is impractical to make the repair by the SELLER, and if
forwarding by the SELLER of replacement part, and materials cannot be
accomplished without impairing or delaying the operation of the VESSEL, then, in
any such event, the BUYER shall cause the necessary repairs or replacements to
be made elsewhere at the discretion of the BUYER provided that the BUYER shall,
as soon as possible, give the SELLER notice in writing by telex or telefax of
the time and place such repairs will be made, provided always that the burden of
proof as to the necessity for such repairs and replacements shall rest with the
BUYER, and a written confirmation for such repairs or replacement shall be
obtained from the SELLER. Defects that affect the safety of the VESSEL or her
crew and/or constitute an emergency shall be repaired either by the crew or a
BUYER selected contractor in a manner reasonable under the circumstances without
the SELLER's prior approval and the SELLER shall be notified as to the nature
and extent of repairs as soon as possible after the repairs are undertaken and
such repair work will be subject to the mutual agreement between the parties. If
the VESSEL is not thereby delayed or her operation is not thereby delayed or
impaired, the SELLER shall have the right to verify the nature and extent of the
defects complained of by its own representative(s) or that of Classification
Society. The SELLER shall, in such cases, promptly advise the BUYER, by telex or
telefax, after such examination has been completed, of its acceptance or
rejection of the defects as ones justifying the

remedy under this Article. In all minor cases, the Guarantee Engineer, as
hereinafter provided for, will act for and on behalf of the SELLER.

        In any circumstances, the SELLER shall immediately pay to the BUYER in
United States Dollars by telegraphic transfer the actual cost for such repairs
or replacements including forwarding charges, or at the average cost for making
similar repairs or replacements including forwarding charges as quoted by a
leading shipyard each in China, Singapore, Korea and Spain, whichever is lower:

        remedy under this Article, or

                  (b) If the SELLER neither accepts nor rejects the defects as
        above provided, nor requests arbitration within thirty (30) days after
        its receipt of the BUYER's notice of defects.

        Any dispute shall be referred to arbitration in accordance with the
provisions of Article XIII hereof.

4.      EXTENT OF THE SELLER'S LIABILITY

        The SELLER shall have no obligation and/or liabilities with respect to
defects discovered after the expiration of the period of guarantee specified
above.

        The SELLER shall be liable to the BUYER for defects and damages caused
by any of the defects specified in Section 1 of this Article provided that such
liability of the SELLER shall be limited to damage occasioned within the
guarantee period specified in Paragraph 1 above. The SELLER shall not be
obligated to repair, or to be liable for, damages to the VESSEL, or to any part
of the equipment thereof, due to ordinary wear and tear or caused by defects
other than those specified in Paragraph 1 above, nor shall there be any SELLER's
liability hereunder for defects in the VESSEL, or any part of the equipment
thereof, caused by fire or accidents at sea or elsewhere, or mismanagement,
accidents, negligence, or willful neglect, on the part of the BUYER, its
employees or agents including the VESSEL's officers, crew and passengers, or any
persons on or doing work on the VESSEL other than the SELLER, its employees,
agents or sub-contractors. Likewise, the SELLER shall not be liable for defects
in the VESSEL, or the equipment or any part thereof, due to repairs or
replacement which were made by those other than the SELLER and/or their
sub-contractors, employees or agents.

special loss, or expenses arising from any cause whatsoever including, without
limitation, loss of time, loss of profit or earnings or demurrage directly from

5.      SALE OF THE VESSEL

        (a) In the event of cancellation or rescission of this Contract as above
provided, the SELLER shall have full right and power either to complete or not

proceeds of sale received by the SELLER shall be applied firstly to all expenses
attending such sale and otherwise incurred by the SELLER as a result of the
BUYER's default, and then to payment of all costs of construction of the VESSEL
(such costs of construction, as herein mentioned, shall include but are not
limited to all costs of labor and/or prices paid or to be paid by the SELLER for

materials, equipment, appurtenances and outfit, delivered to the BUILDER for the
VESSEL or built into, or installed in or upon the VESSEL, including the BUYER's
Supplies, fully insured with first class Chinese insurance companies for

        The amount of such insurance coverage shall, up to the date of delivery
of the VESSEL, be in an amount at least equal to, but not limited to, the
aggregate of the payments made by the BUYER to the SELLER including the value of
the BUYER's Supplies. The policy referred to hereinabove shall be taken out in

2.      APPLICATION OF RECOVERED AMOUNT

        (a)       Partial Loss:

                  In the event the VESSEL shall be damaged by any insured cause
        whatsoever prior to acceptance and delivery thereof by the BUYER and in
        the further event that such damage shall not constitute an actual or a
        constructive total loss of the VESSEL, the SELLER shall apply the amount
        recovered under the insurance policy referred to in Section 1 of this
        Article to the repair of such damage satisfactory to the Classification
        Society and other institutions or authorities as described in the
        Specifications without additional expenses to the BUYER.

        (b)       Total Loss:

                          (i) By the mutual agreement between the parties
                  hereto, proceed in accordance with terms of this Contract, in
                  which case the amount recovered under said insurance policy
                  shall be applied to the reconstruction and/or repair of the
                  VESSEL's damages and/or reinstallation of BUYER's supplies
                  without additional expenses to the BUYER, provided the parties
                  hereto shall have first agreed in writing as to such
                  reasonable extension of the Delivery Date and adjustment of
                  other terms of this Contract including the Contract Price as
                  may be necessary for the completion of such reconstruction; or

                          (ii) If due to whatever reasons the parties fail to
                  agree on the above, then the BUYER shall deliver a written
                  notice of rejection to SELLER and the SELLER shall refund
                  immediately to the BUYER the amount described in Article II,
                  Section 7, whereupon this Contract shall be deemed to be
                  canceled and all rights, duties, liabilities and obligations
                  of each of the parties to the other shall terminate forthwith.

                          (iii) Notwithstanding the provisions of (i) and (ii)
                  above, Seller may elect to postpone delivery of the Vessel
                  subject to the provisions of Article III, Section (1)(a).

                  Within thirty (30) days after receiving telex or telefax
        notice of any damage to the VESSEL constituting an actual or a
        constructive total loss, the BUYER shall notify the SELLER in writing or
        by telex of its agreement or disagreement under this sub-paragraph. In
        the event the BUYER fails to so notify the SELLER, then such failure
        shall be construed as a disagreement on the part of the BUYER. This
        Contract shall be deemed as rescinded and canceled and the BUYER shall
        receive the refund as hereinabove provided and the provisions hereof
        shall apply.

3.      TERMINATION OF THE SELLER'S OBLIGATION TO INSURE

        The SELLER's obligation to insure the VESSEL hereunder shall cease and
terminate forthwith upon Delivery thereof to and acceptance by the BUYER.

        Should any dispute of any nature arise in respect of this Contract, its
performance or interpretation which is not decided in accordance with Article
XIII, Section 2 below, such dispute shall be settled by arbitration in London,
England in accordance with the rules of the London Maritime Arbitrators
Association Inc. and otherwise in accordance with the provisions of the Laws of
England. The party who desires arbitration of any such dispute shall give
written notice to the other party. The notice shall state the name and address
of the arbitrator whom it appoints and describe the specific nature of the
particular dispute. Such notice shall be sent by registered air mail and shall
be addressed in the manner set forth in Article XIX, and the other party shall,
within thirty (30) days following the receipt of said notice, give written
notice to the party requesting the arbitration as to the name and address of the
arbitrator whom it appoints, which notice shall be sent by registered air mail
and shall be addressed in the manner set forth in Article XIX, provided that if
the other party should fail to so appoint its arbitrator, the arbitrator
appointed by the party desiring the arbitration may proceed with the arbitration
hearing and issue an award. Otherwise the two arbitrators so chosen shall select
a third arbitrator. The applicable law of England on all matters at issue shall
apply. A judgement based upon the decision of the majority of the arbitrators or
the sole arbitrator, as the case may be, may be entered in the appropriate court
of any country having jurisdiction of either party. The arbitrators shall also
decide which party, or the extent to which each party, shall pay costs of
arbitration. Unless and to the extent otherwise determined by the arbitrator(s),
reference to arbitration shall not relieve the BUILDER of its obligation
diligently to proceed with the construction, completion and delivery of the
VESSEL, but the majority of the arbitrators or the sole arbitrator, as the case
may be, shall decide the extent to which the Delivery Date shall be extended by
virtue of the dispute having been referred to arbitration.

2.      ALTERNATIVE ARBITRATION BY AGREEMENT

        Notwithstanding the preceding provisions of this Article, it is
recognized that in the event of any dispute or difference of opinion arising in
regard to the construction of the VESSEL, her machinery and equipment, or
concerning the quality of materials or workmanship thereof or thereon, such
dispute may be referred to the Classification Society upon mutual agreement of
the parties hereto. In such case, the opinion of the Classification Society
shall be final and binding on the parties hereto.

3.      NOTICE OF AWARD

        Notice of any award shall immediately be given in writing or by telex
confirmed in writing to the SELLER and the BUYER.

c/o Cambridge Petroleum Transport Corporation
535 Madison Avenue
19th Floor
New York, New York 10022


Dear Sirs:

At the request of China Shipbuilding Trading Company, Limited ("CSTC") and
Jiangnan Shipyard (the "Builder" and, together with CSTC, the "SELLER") and in
consideration of Navigator Holdings PLC (the "BUYER") agreeing to pay SELLER the
installments of the contract price (the "Contract Price") pursuant to the
Amended and Restated Shipbuilding Contract dated the 26th day of June, 1997, as
amended, supplemented or otherwise modified from time to time (hereinafter
called the "Contract") made by and between the BUYER and the SELLER for the
construction of one (1) 22,000 cubic meter liquefied ethylene gas carrier having
Hull No. 2245 (hereinafter called the "VESSEL"), The Export Import Bank of China
the "Bank") the undersigned, do guarantee the payment (and not merely the
collectability of the same) to the BUYER by the SELLER immediately upon demand
of an amount up to but not exceeding a total amount as set forth in Schedule 1
hereto (calculated in accordance with the immediately following paragraph),
together with simple interest thereon calculated at the rate of ten percent
(10.0%) per annum on the basis of a 360 day year from and including the date of
receipt of demand to but not including the date of remittance by telegraphic
transfer of such refund.

Subject to BUYER making installment payments in accordance with Article II of
the Contract, the amount of this Guarantee will be automatically increased
during the term of this Guarantee and shall be equal to the sum of: (i) the
amount set forth on Schedule 1 hereto calculated as of the first day of the
calendar month in which the Date

                                                       Amended and Restated
                                                     Shipbuilding Contract H2245

of Rejection occurs; and (ii) an amount equal to the product of (X) the
difference between (1) the amount set forth on Schedule 1 hereto calculated as
of the first day of the calendar month immediately succeeding the month in which
the Date of Rejection occurs and (2) the amount set forth on Schedule 1 hereto
as of the first day of the month in which the Date of Rejection of the vessel
under the Contract occurs and (y) a fraction the numerator of which is numeric
day of the month of the date on which the Refund Amount (as hereinafter defined)
is actually paid and the denominator of which is 30 (collectively, the "Refund
Amount").

BUYER's right to demand payment under this Guarantee shall become effective on
the earlier to occur of (i) April 1, 2001, (ii) the date on which the SELLER
fails to pay any liquidated damages payable to BUYER as provided in Section 1(a)
of Article III of the Contract, (iii) upon the cancellation, termination or
rescission of the Contract by the BUYER in accordance with the terms of Contract
as set forth in Article III, 1(a), 2(c), 3(c), 4(c), 5(c), Article X, Article
XII 2(b), or Article XVI (b) or (c), or (iv) the insolvency or bankruptcy of
BUILDER.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to us by the BUYER.

Payment under this Guarantee is available at the counters of ______________ Bank
against presentation of the BUYER's signed statement issued in the form attached
hereto as Appendix A ("Notice of Demand"). If the Notice of Demand is received
by the Bank by 12:00 noon local time on a banking day, the Bank shall pay the
Refund Amount (plus interest thereon) in immediately available funds within ten
(10) banking days. If the Notice of Demand is received by the Bank after 12:00
noon local time on a banking day, the Bank shall pay the Refund Amount (plus
interest thereon) in immediately available funds within eleven (11) banking
days.

This Guarantee is available for one payment only, whether for the full amount
hereof or any part thereof, as may be demanded by the BUYER. In the event that
the BUYER's demand is for a lesser amount than the amount of this Guarantee, the
interest payable will be calculated on the amount of the BUYER's demand and not
on the amount of this Guarantee.

We agree that this Guarantee shall be a continuing guarantee and (i) shall not
be impaired or discharged by the granting of time or any other indulgence to the
SELLER, or any other forbearance (whether as to payment, time, performance, or
otherwise) which might, but for this provision, have any such effect; (ii) shall
not be conditioned or contingent upon the BUYER's pursuit of any remedy that it
has against the SELLER;

                                       A-2

                                                       Amended and Restated
                                                     Shipbuilding Contract H2245

and (iii) shall be unconditional irrespective of any other circumstance that
might otherwise constitute a legal or equitable discharge of a surety or
guarantor under applicable law, and we hereby waive any and all rights (whether
by counterclaim, set off or otherwise) and defenses at law or in equity that may
be available to us by reason of such circumstance.

This Guarantee shall become effective from the time of the actual receipt of the
first installment by the SELLER from the BUYER under the Contract and the Refund
Amount payable under this Guarantee shall correspond to the total installment
payments actually made by the BUYER to the SELLER from time to time under the
Contract prior to the delivery of the VESSEL including applicable interest.

This Guarantee shall expire and become null and void on the earlier to occur of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
the Bank of either a copy of the Protocol of Delivery and Acceptance of the
VESSEL, purportedly signed by the BUYER and the SELLER and issued in the form
attached hereto as Appendix B or a copy of the Certificate of Completion of the
Vessel signed by the respective parties thereto in the form attached hereto as
Appendix C; or (iii) 5:00 p.m. New York time on May 1, 2001, in any such case
this Guarantee shall be returned to us; provided, the Bank further agrees that
its obligations hereunder shall continue to be effective or reinstated, as the
case may be, if at any time any payment, or any part thereof, made by the SELLER
is rescinded or must otherwise be restored by the BUYER upon the bankruptcy or
reorganization of the SELLER.

Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER confirmed by an arbitrator stating that the BUYER's
claim to cancel the Contract or the BUYER's claim for refundment thereunder has
been disputed and referred to arbitration in accordance with the provisions of
the Contract, the period of validity of this Guarantee shall be extended until
thirty (30) days after the final award shall be rendered in the arbitration and
a copy thereof acknowledged by the arbitrators. In such case, this Guarantee
shall not be available unless and until such acknowledged copy of the final
award in the Arbitration justifying the BUYER's claim is presented to us;
subject to any appeal of such final award which may be permitted under English
law; provided the Refund Amount shall be adjusted to reflect the delay resulting
from such arbitration and shall be calculated in accordance with Schedule 1
hereto to the date payment is actually made.

Dear Sirs:

At the request of China Shipbuilding Trading Company, Limited ("CSTC") and
Jiangnan Shipyard (the "Builder" and together with CSTC collectively called the
"SELLER") and in consideration of Navigator Holdings, PLC (the "BUYER") agreeing
to pay SELLER the installments of the contract price (the "Contract Price")
pursuant to the Amended and Restated Shipbuilding Contracts dated the 26th day
of June, 1997, as amended, supplemented or otherwise modified from time to time
(hereinafter called the "Contracts") made by and between the BUYER and the
SELLER for the construction of five (5) 22,000 cubic meter liquefied ethylene
gas carriers respectively having Hull Nos. 2245, 2246, 2247, 2248 and 2249
(hereinafter called the "VESSELS"), Export-Import Bank of China (the "Bank")
guarantees the payment (and not merely the collectability of the same) to the
BUYER by the SELLER, immediately upon demand, of an amount up to but not
exceeding a total aggregate amount of United States Dollars Twenty Six Million
Seven Hundred Thousand (US$26,700,000) (the "Payment Amount"), if and when the
same or any part thereof becomes payable to BUYER from the SELLER under any
Contract or Contracts if any such Contract or Contracts are cancelled by the
BUYER in accordance with the terms (Article III, 1(a), 2(c), 3(c), 4(c), 5(c),
Article X, Article XII 2(b) and Article XVI (b) and (c)) of such Contract or
Contracts (any a "Cancellation Event"). This Performance Bond shall become
effective upon actual receipt in full by the SELLER of the initial installment
due under each of the Contracts.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to the BANK by the BUYER.


                                       B-1

                                                       Amended and Restated
                                                     Shipbuilding Contract H2245

Payment under this Performance Bond is available at the counters of
Export-Import Bank of China in __________________ against presentation of the
BUYER's signed statement issued in the form attached hereto as Appendix A
("Notice of Demand"). The Notice of Demand shall set forth the dollar amount to
be paid to the BUYER under this Performance Bond, which amount shall be based
upon Schedule 1 attached hereto (the "Demand Amount") provided such Demand
Amount shall not exceed the Payment Amount. As to any date on which a Notice of
Demand is presented, the Demand Amount shall be equal to the amount set forth
opposite the calendar month in which such Notice of Demand is presented under
the column heading specified in the Notice of Demand. If the Notice of Demand is
received by the Bank by 12:00 noon local time on a banking day, the Bank shall
pay the Demand Amount in immediately available funds within ten (10) banking
days. If the Notice of Demand is received by the Bank after 12:00 noon local
time on a banking day, the Bank shall pay the Demand Amount in immediately
available funds within eleven (11) banking days.

The right of the BUYER to demand payment under this Performance Bond by
presentation of a Notice of Demand shall become effective on the earlier to
occur of (i) April 1, 2001, (ii) the date on which the SELLER fails to pay any
liquidated damages payable to BUYER as provided in Section 1(a) of Article III
of the Contracts, (iii) the occurrence of a Cancellation Event or (iv) the
bankruptcy or insolvency of the Builder.

This Performance Bond is available for one payment only, whether for the full
amount hereof or any part thereof, as may be demanded by the BUYER.

We agree that this Performance Bond shall be a continuing guarantee and (i)
shall not be impaired or discharged by the granting of time or any other
indulgence to the SELLER, or any other forbearance (whether as to payment, time,
performance, or otherwise) which might, but for this provision, have any such
effect; (ii) shall not be conditioned or contingent upon the BUYER's pursuit of
any remedy that it has against the SELLER; and (iii) shall be unconditional
irrespective of any other circumstance that might otherwise constitute a legal
or equitable discharge of a surety or guarantor under applicable law, and we
hereby waive any and all rights (whether by counterclaim, set off or otherwise)
and defenses at law or in equity that may be available to us by reason of such
circumstance.

This Performance Bond shall expire and become null and void on the earlier of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
Bank of a copy of the Protocol of Acceptance and Delivery or Certificates of
Completion for each of the five (5) VESSELS in the form of Appendix B or
Appendix C to this Performance Bond; or (iii) 5:00 p.m. New York time on May 1,
2001, in any such case this Performance Bond shall be returned to us; provided,
the Bank further agrees that its obligations hereunder shall continue to be
effective or reinstated, as the case may be, if at any time any payment, or any
part thereof, made by the SELLER is rescinded or must otherwise be restored by
the BUYER upon the bankruptcy or reorganization of the SELLER.

Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER stating that the BUYER's claim to cancel the Contracts
or the BUYER's claim for payment thereunder has been disputed and referred to
arbitration in accordance with the provisions of the Contracts, the period of
validity of this Performance Bond shall be extended until thirty (30) days after
the final award shall be rendered in the arbitration and a copy thereof
acknowledged by the arbitrators. In such case, this Performance Bond shall not
be available unless and until such acknowledged copy of the final award in the
Arbitration justifying the BUYER's claim is presented to us; subject to any
appeal of such final award which may be permitted under English law.

Dear Sirs:

At the request of Tractebel Gas Engineering GmBH and in consideration of
Navigator Holdings, PLC (the "BUYER") agreeing to pay China Shipbuilding Trading
Company, Limited ("CSTC") and Jiangnan Shipyard (the "Builder" together with
CSTC collectively called the "SELLER") the installments of the contract price
(the "Contract Price") pursuant to the Amended and Restated Shipbuilding
Contracts dated the 26th day of June, 1997, as amended, supplemented or
otherwise modified from time to time (hereinafter called the "Contracts") made
by and between the BUYER and the SELLER for the construction of five (5) 22,000
cubic meter liquefied ethylene gas carriers having Hull Nos. 2245, 2246, 2247,
2248 and 2249 (hereinafter called the "VESSELS"), Generale de Banque (the
"Bank") guarantees the payment (and not merely the collectability of the same)
to the BUYER by the SELLER, immediately upon demand, of an amount up to but not
exceeding a total aggregate amount of United States Dollars Thirteen Million
Three Hundred Thousand (US$13,300,000) (the "Payment Amount"), if and when the
same or any part thereof become payable to BUYER from the SELLER under any
Contract or Contracts if any such contract or contracts are cancelled by the
BUYER in accordance with the terms (Article III, 1(a), 2(c), 3(c), 4(c), 5(c),
Article X, Article XII 2(b) and Article XVI(b) and (c)) of the Contracts (any a
"Cancellation Event"). This Performance Bond shall become effective upon payment
of the initial installment under each of the Contracts.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to the BANK by the BUYER.

Payment under this Performance Bond is available at the counters of
_______________ against presentation of the BUYER's signed statement issued in
the form attached hereto as Appendix A ("Notice of Demand"). The Notice of
Demand shall set forth the dollar amount to be paid to the

                                       C-1

<PAGE>



BUYER under this Performance Bond, which amount shall be based upon Schedule 1
attached hereto (the "Demand Amount") provided such Demand Amount shall not
exceed the Payment Amount. As to any date on which a Notice of Demand is
presented, the Demand Amount shall be equal to the amount set forth opposite the
calendar month in which such Notice of Demand is presented and under the column
heading specified in the Notice of Demand less the amount paid by the
Export-Import Bank of China under such Bank's Irrevocable Performance Bond dated
_______, 1997 (the "Ex-Im Performance Bond"). In addition, the BUYER's right to
demand payment as provided above is subject to delivery by BUYER to the Bank of
a copy of the notice of demand presented to the Export-Import Bank of China
under the Ex-Im Performance Bond in the amount of US$26,700,000 and evidence
that such amount has been paid.

If the Notice of Demand is received by the Bank by 12:00 noon local time on a
business day, the Bank shall pay the Demand Amount in immediately available
funds on the same business day. If the Notice of Demand is received by the Bank
after 12:00 noon local time on a business day, the Bank shall pay the Demand
Amount in immediately available funds on the next succeeding business day.

The right of the BUYER to demand payment under this Performance Bond shall
become effective on the earlier to occur of (i) April 1, 2001, (ii) the date on
which the SELLER fails to pay any liquidated damages payable to BUYER as
provided in Section 1(a) of Article III of the Contracts, (iii) the occurrence
of a Cancellation Event or (iv) the bankruptcy or insolvency of the Builder.

This Performance Bond is available for one payment only, whether for the full
amount hereof or any part thereof, as may be demanded by the BUYER.

We agree that this Performance Bond shall be a continuing guarantee and (i)
shall not be impaired or discharged by the granting of time or any other
indulgence to the SELLER, or any other forbearance (whether as to payment, time,
performance, or otherwise) which might, but for this provision, have any such
effect; (ii) shall not be conditioned or contingent upon the BUYER's pursuit of
any remedy that it has against the SELLER; and (iii) shall be unconditional
irrespective of any other circumstance that might otherwise constitute a legal
or equitable discharge of a surety or guarantor under applicable law, and we
hereby waive any and all rights (whether by counterclaim, set off or otherwise)
and defenses at law or in equity that may be available to us by reason of such
circumstance.

This Performance Bond shall expire and become null and void on the earlier of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
Bank of a copy of the Protocol of Acceptance and Delivery and/or Certificates of
Completion for each of the five (5) VESSELs in the form of Appendix B or
Appendix C to this Performance Bond; and (iii) 5:00 p.m. New York time on May 1,
2001, in any such case this Performance Bond shall be returned to us; provided,
the Bank further agrees that its obligations hereunder shall continue to be
effective or reinstated, as the case may be, if at any time any payment, or any
part thereof, made by the SELLER is rescinded or must otherwise be restored by
the BUYER upon the bankruptcy or reorganization of the SELLER.


                                       C-2

Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER confirmed by an arbitrator stating that the BUYER's
claim to cancel the Contracts or the BUYER's claim for refundment thereunder has
been disputed and referred to arbitration in accordance with the provisions of
the Contract, the period of validity of this Performance Bond shall be extended
until thirty (30) days after the final award shall be rendered in the
arbitration and a copy thereof acknowledged by the arbitrators. In such case,
this Performance Bond shall not be available unless and until such acknowledged
copy of the final award in the Arbitration justifying the BUYER's claim is
presented to us; subject to any appeal of such final award which may be
permitted under English law.

This Performance Bond is governed by and enforced and construed in accordance
with the laws of England.

                   made in conformity with the Amended and Restated

                   otherwise modified from time to time (hereinafter called the

                  liquidated damages payment, BUYER, in its sole discretion, may
                  either (i) reject the VESSEL or (ii) waive its right to
                  receive the payment of liquidated damages and further reduce
                  the Contract Price for the VESSEL by an amount equal to the
                  liquidated damages which would have been payable.
                  Notwithstanding any other provision contained in this Contract
                  to the contrary, this Contract shall be deemed rescinded on
                  April 1, 2001 and the Buyer shall be entitled to receive the
                  amounts set forth in Article II, Section 7(a) above.

                          Any waiver by the BUYER of its right to receive
                  liquidated damages monthly in advance is not a waiver of the
                  BUYER's right to (a) demand payment of such liquidated damages
                  at a later date, (b) demand monthly advances as to Liquidated
                  Damages for any subsequent months of delay or (c) reject the
                  VESSEL at such later date if liquidated damages are not paid
                  upon demand. The liquidated damages calculated pursuant to
                  this paragraph are in addition to the reduction in the fifth
                  installment of the Contract Price as calculated pursuant to
                  (ii) above for the Original Delay Period.

                          (iv) In the event that the BUYER elects to reject the
                  VESSEL as allowed under this Article III, Section 1(a), the
                  SELLER shall immediately repay to the BUYER the amounts set

                          Original Delivery Date plus the Permissible Delay for
                          such Vessel,

                          (A) above, SELLER shall have the right in its sole
                          discretion to designate either the Vessel or any
                          Sister Vessel as to which Vessel will be subject to a
                          Permissible Delay.

        (b)       Early Delivery Price Adjustment:

                          If the SELLER notifies the BUYER by facsimile that the

                  than the Original Delivery Date and notice is properly given,
                  then a bonus shall be added to the Contract Price at a rate of

                  for each full day earlier than the Original Delivery Date.

                          The total increase of the Contract Price for the

from, the work to be performed in connection with such construction. If due to
whatever reasons, the parties hereto shall fail to agree on the adjustment of
the Contract Price or extension of time of delivery or providing additional
security to the SELLER or modification of any terms of this Contract which are
necessitated by such modifications and/or changes, then the SELLER shall have no

construction of the VESSEL is required to conform, are altered or changed by the
Classification Society or the other regulatory bodies authorized to make such
alterations or changes, the SELLER and/or the BUYER, upon receipt of the notice
thereof, shall transmit such information in full to each other in writing,
whereupon within twenty one (21) days after receipt of the said notice by the
BUYER from the SELLER or vice versa, the BUYER shall instruct the SELLER in
writing as to the alterations or changes, if any, to be made in the VESSEL which
the BUYER, in its sole discretion, shall decide. The SELLER shall promptly
comply with such alterations or changes, if any in the construction of the
VESSEL, provided that the BUYER shall first agree:

                  (i) As to any increase or decrease in the guaranteed
        deadweight and/or cargo tank capacity and for speed of the VESSEL, if
        such compliance results in increased or reduced deadweight and/or cargo
        tank capacity and speed; and/or

                  (ii) As to any other alterations in the terms of this Contract
        or of Specifications or both, if such compliance makes such alterations
        of the terms necessary.

        Agreement as to such alterations or changes under this Paragraph shall
be made in the same manner as provided above for modifications and/or changes of
the Specifications and/or Plans.

        (b) If, due to whatever reasons, the parties shall fail to agree on the
increase or decrease of the guaranteed speed, deadweight and cargo tank 
capacity,

or any alteration of the terms of this Contract, if any, then the SELLER shall
be entitled to proceed with the construction of the VESSEL in accordance with,
and the BUYER shall continue to be bound by, the terms of this Contract and
Specifications without making any such alterations or changes.

        (c) The BUYER and the SELLER hereby agree to make best efforts to avoid
the application and/or minimize the effect of any change in the rules and
regulations of the Classification Society as to the Specifications. If the BUYER
and the SELLER are unsuccessful in avoiding the application of such change in
rules and regulations, then the SELLER shall effect any modifications and/or
changes in Specifications without adjustment to the Contract Price and the BUYER
shall grant to the SELLER the right to extend the Delivery Date (if necessary)
for a maximum period of up to twelve (12) days.

3.      SUBSTITUTION OF MATERIALS AND/OR EQUIPMENT

        In the event that any of the materials and/or equipment required by the
Specifications or otherwise under this Contract for the construction of the
VESSEL cannot be procured in time to effect delivery of the VESSEL, the SELLER
may, provided the SELLER shall provide adequate evidence and the BUYER so agrees
in writing, supply other materials and/or equipment of the equivalent quality,
capable of meeting the requirements of the Classification Society and of the
rules, regulations, requirements and recommendations with which the construction
of the VESSEL must comply.

4.      BUYER'S SUPPLIED ITEMS

        The BUYER shall deliver to the SELLER at its shipyard the items as
specified in the Specifications which the BUYER shall supply for its own account
(the "BUYER's Supplies") by the time designated by the SELLER.

        The delay in the delivery or the failure to deliver by the BUYER of any
BUYER's Supplies within the time specified shall not extend the Delivery Date.

        However, if the delay in delivery of the BUYER's Supplies should exceed
fifteen (15) days, the SELLER shall be entitled to proceed with construction of
the VESSEL without installation of such items in or onto the VESSEL and the
BUYER shall accept the VESSEL so completed.

        The BUILDER shall be responsible for storing and handling of the BUYER's
Supplies as specified in the Specifications after delivery to the BUILDER and
shall install them on board the VESSEL at the BUILDER's expenses.

        Upon arrival of such shipment of the BUYER's Supplies, both parties
shall undertake an joint unpacking inspection. If any damaged BUYER's supplies
are found to be unsuitable for installation, the BUILDER shall be entitled to
refuse to accept the BUYER's Supplies.

                                   ARTICLE VI
                                     TRIALS

1.      NOTICE

        The BUYER and the Supervisor shall receive from the SELLER at least
thirty (30) days notice in advance and seven (7) days definite notice in advance
in writing by telex or telefax, of the time and place of the VESSEL's sea trial
as described in the Specifications (hereinafter referred to as "the Trial Run")
and the BUYER and the Supervisor shall promptly acknowledge receipt of such
notice. The BUYER's representatives and/or the Supervisor shall be on board the
VESSEL to witness such Trial Run, and to check upon the performance of the
VESSEL during the same. Failure of the BUYER's representatives to be present at
the Trial Run of the VESSEL, after due notice to the BUYER and the Supervisor as
provided above, shall have the effect to extend the date for delivery of the
VESSEL by the period of delay caused by such failure to be present. However, if
the Trial Run is delayed more than five (5) days by reason of the failure of the
BUYER's representatives to be present after receipt of due notice as provided
above (other than due to the failure by the BUYER's representative to obtain a
visa to enter China), then in such event, the BUYER shall be deemed to have
waived its right to have its representatives on board the VESSEL during the
Trial Run, and the BUILDER may conduct such Trial Run without the BUYER's
representatives being present, and in such case the BUYER shall be obliged to
accept the VESSEL on the basis of a certificate jointly signed by the BUILDER
and the Classification Society certifying that the VESSEL, after Trial Run
subject to minor alterations and corrections as provided in this Article, if
any, is found to conform to the Contract and Specifications and is satisfactory
in all respects. The SELLER hereby warrants that the necessary visa for the
BUYER's representatives to enter China will be issued in order on demand and
without delay otherwise the Trial Run shall be postponed until the BUYER's
representatives have arrived at the BUILDER's Shipyard. However, should the
nationalities and other personal particulars of the BUYER's representatives be
not acceptable to the SELLER in accordance with its best

understanding of the relevant rules, regulations and/or Laws of the People's
Republic of China then prevailing, then the SELLER shall so notify the BUYER and
the BUYER shall endeavor to effect the replacement of all or any of such
representatives. The Delivery Date as stipulated in Article VII hereof shall not
be extended by any delays caused by the BUYER's replacement of its
representatives pursuant to the SELLER's request. In the event of unfavorable
weather on the date scheduled for the Trial Run, the same shall take place on
the first available day thereafter that the weather conditions permit. The
parties hereto recognize that the weather conditions in Chinese waters in which
the Trial Run is to take place are such that great changes in weather may arise
momentarily and without warning and, therefore, it is agreed that if during the
Trial Run of the VESSEL, the weather should suddenly become unfavorable, as
would have precluded the continuance of the Trial Run, the Trial Run of the
VESSEL shall be discontinued and postponed until the first favorable day next
following, unless the BUYER assents in writing by telex or telefax of its
acceptance of the VESSEL on the basis of the Trial Run made prior to such sudden
change in weather conditions. In the event that the Trial Run is postponed
because of unfavorable weather conditions, the Delivery Date shall not be
extended other than pursuant to Article VIII hereof.

2.      HOW CONDUCTED

        (a) All expenses in connection with Trial Run of the VESSEL are to be
for the account of the BUILDER, who, during the Trial Run and when subjecting
the VESSEL to Trial Run, is to provide, at its own expense, the necessary crew
to comply with conditions of safe navigation. The Trial Run shall be conducted
in the manner prescribed in the Specifications and shall prove fulfillment of
the performance required for the Trial Run as set forth in the Specifications.

        The course of Trial Run shall be determined by the BUILDER and shall be
conducted within the trial waters equipped with speed measuring facilities.

        (b) The BUILDER shall provide the VESSEL with the required quantities of
water and fuel oil with exception of lubrication oil, hydraulic oil and greases
which shall be supplied by the BUYER according to the BUILDER's schedule which
shall be forwarded to the BUYER by the BUILDER for the conduct of the Trial Run
or Trial Runs as prescribed in the Specifications. The fuel oil supplied by the
SELLER, and lubricating oil, hydraulic oil and greases supplied by the BUYER
shall be in accordance with the applicable engine Specifications, and the cost
of the quantities of water, fuel oil, lubricating oil, hydraulic oil and greases
consumed during the Trial Run or Trial Runs shall be for the account of the
BUILDER.

stores necessary for the conduct of the Trial Run. The necessary ballast (fresh
water, sea water or any other ballast as may be required) to bring the VESSEL to
the trial load draft as specified in the Specifications, shall be for the
BUILDER's account.

4.      METHOD OF ACCEPTANCE OR REJECTION

        (a) Upon notification of the BUILDER of the completion of the Trial Run
of the VESSEL attached with the trial result, the BUYER or the BUYER's
Supervisor shall within six (6) business days thereafter, notify the BUILDER in
writing by telex or telefax of its acceptance of the VESSEL or of its rejection
of the VESSEL together with the reasons therefor.

        (b) However, should the result of the Trial Run indicate that the VESSEL
or any part thereof including its equipment does not conform to the requirements
of this Contract and Specifications the BUILDER shall investigate with the
Supervisor the cause of failure and shall take proper steps to remedy the same
and shall make whatever corrections and alterations and/or re-Trial Run or Trial
Runs as may be necessary without extra cost to the BUYER, and upon notification
by the BUILDER of completion of such alterations or corrections and/or re-trial
or re-trials, the BUYER shall, within six (6) business days thereafter, notify

Trial Run or further tests or trials, as the case, may be, of the VESSEL shall
be referred to the Classification Society as provided in Article XIII Section 2
hereof.

        (e) Nothing herein shall preclude the BUYER from accepting the VESSEL
with its qualifications and/or remarks following the Trial Run and/or further
tests or trials as

aforesaid and the SELLER shall be obliged to comply with and/or remove such
qualifications and/or remarks (if such qualifications and/or remarks are
acceptable to the SELLER) at the time before effecting delivery of the VESSEL to
the BUYER under this Contract.

5.      DISPOSITION OF SURPLUS CONSUMABLE STORES

        Should any amount of fuel oil, fresh water, or other unbroached
consumable stores furnished by the BUILDER for the Trial Run or Trial Runs
remain on board the VESSEL at the time of acceptance thereof by the BUYER, the
BUYER agrees to buy the same from the SELLER at the purchasing price at the port

installment the amount of such payment as provided in Article II, Section 4 of
this Contract.

6.      EFFECT OF ACCEPTANCE

        The BUYER's acceptance of the VESSEL in writing by telex or telefax
notification sent to the SELLER, in accordance with the provisions set out
above, shall be final and binding so far as conformity of the VESSEL to this
Contract and the Specifications is concerned, and shall preclude the BUYER from
refusing Delivery (as defined below) by the SELLER of the VESSEL, as hereinafter
provided, if the SELLER complies with all other procedural requirements for
delivery as hereinafter set forth.

        (g) If delays are incurred relating to the use of the VESSEL, caused by
an unsuccessful gas trial, remedial works and retrials for which the SELLER is
responsible, with the consequence that the classification certificate has not
been issued, will exceed more than twenty (20) days as from the commencement of
the Gas Trials, the SELLER shall, notwithstanding the provisions contained in
Article IX Section 2 and Section 4, pay to the BUYER as liquidated damages
United States Dollars Ten Thousand (US$10,000) for each day of such excess delay

beyond the control of the BUILDER or of its sub-contractors, as the case may be,
or by force majeure of any description, whether of the nature indicated by the
forgoing or not, or by destruction of the BUILDER or works of the BUILDER or its
sub-contractors, or of the VESSEL or any part thereof, by fire, flood, or other
causes beyond the control of the SELLER or its sub-contractors as the case may
be, then, in the event of delay due to the happening of any of the
aforementioned contingencies, the SELLER shall not be liable for such delay and
the time for delivery of the VESSEL under this Contract shall be extended
without any reduction in the Contract Price subject nevertheless to (i) the
provisions of Section 1(a) of Article III as to reduction in Contract Price,
(ii) the BUYER's right of termination under Section 1(a) of Article III and
(iii) all relevant provisions of this Contract which authorize and permit
extension of the time of delivery of the VESSEL.

2.      NOTICE OF DELAY

        Within fourteen (14) days from the date of commencement of any delay on
account of which the SELLER claims that it is entitled under this Contract to an
extension of the time for delivery of the VESSEL, the SELLER shall advise the
BUYER in writing by telex or telefax of the date such delay commenced, and
reasons therefor.

        Likewise within fourteen (14) days after such delay ends, the SELLER
shall advise the BUYER in writing by telex or telefax of the date such delay
ended, and also shall specify the maximum period of the time by which the date
for delivery of the VESSEL is extended by reason of such delay. Failure of the
BUYER to acknowledge the SELLER's notification of any claim for extension of the
Delivery Date within fourteen (14 ) days after receipt by the BUYER of such
notification, shall be deemed to be a waiver by the BUYER of its right to object
to such extension.

                               WARRANTY OF QUALITY

1.      GUARANTEE OF MATERIAL AND WORKMANSHIP

        The SELLER, for a period of twelve (12) months following delivery to the
BUYER of the VESSEL, guarantees the VESSEL, her hull and machinery and all parts
and equipment thereof that are manufactured or furnished or supplied by the
SELLER and/or its sub-contractors under this Contract including material,
equipment (however excluding any parts for the VESSEL which have been supplied
by or on behalf of the

BUYER) against all defects which are due to defective materials, and/or poor
workmanship or failure to construct in conformity with the Specifications.

2.      NOTICE OF DEFECTS

        The BUYER shall notify the SELLER in writing by telex or telefax, as
promptly as possible, after discovery of any defect or deviations for which a
claim is made under this guarantee. The BUYER's written notice shall describe
the nature of the defect and the extent of the damage caused thereby. The SELLER
shall have no obligation under this guarantee for any defects discovered prior
to the expiry date of the guarantee, unless notice of such defects is received
by the SELLER not later than thirty (30) days after such expiry date. Telexed or
telefaxed advice with brief details explaining the nature of such defect and
extent of damage within thirty (30) days after such expiry date and that a claim
is forthcoming will be sufficient to comply with the requirements as to time.

3.      REMEDY OF DEFECTS

        The SELLER shall remedy at its expense any defect, against which the
VESSEL or any part of the equipment thereof is guaranteed under this Article by
making all necessary repairs and/or replacement. Such repairs and/or replacement
will be made by the SELLER.

        However, if it is impractical to make the repair by the SELLER, and if
forwarding by the SELLER of replacement part, and materials cannot be
accomplished without impairing or delaying the operation of the VESSEL, then, in
any such event, the BUYER shall cause the necessary repairs or replacements to
be made elsewhere at the discretion of the BUYER provided that the BUYER shall,
as soon as possible, give the SELLER notice in writing by telex or telefax of
the time and place such repairs will be made, provided always that the burden of
proof as to the necessity for such repairs and replacements shall rest with the
BUYER, and a written confirmation for such repairs or replacement shall be
obtained from the SELLER. Defects that affect the safety of the VESSEL or her
crew and/or constitute an emergency shall be repaired either by the crew or a
BUYER selected contractor in a manner reasonable under the circumstances without
the SELLER's prior approval and the SELLER shall be notified as to the nature
and extent of repairs as soon as possible after the repairs are undertaken and
such repair work will be subject to the mutual agreement between the parties. If
the VESSEL is not thereby delayed or her operation is not thereby delayed or
impaired, the SELLER shall have the right to verify the nature and extent of the
defects complained of by its own representative(s) or that of Classification
Society.

The SELLER shall, in such cases, promptly advise the BUYER, by telex or telefax,
after such examination has been completed, of its acceptance or rejection of the
defects as ones justifying the remedy under this Article. In all minor cases,
the Guarantee Engineer, as hereinafter provided for, will act for and on behalf
of the SELLER.

        In any circumstances, the SELLER shall immediately pay to the BUYER in
United States Dollars by telegraphic transfer the actual cost for such repairs
or replacements including forwarding charges, or at the average cost for making
similar repairs or replacements including forwarding charges as quoted by a
leading shipyard each in China, Singapore, Korea and Spain, whichever is lower:

                  (a) upon the SELLER's acceptance of the defects as justifying 
        remedy under this Article, or

                  (b) If the SELLER neither accepts nor rejects the defects as
        above provided, nor requests arbitration within thirty (30) days after
        its receipt of the BUYER's notice of defects.

        Any dispute shall be referred to arbitration in accordance with the
provisions of Article XIII hereof.

4.      EXTENT OF THE SELLER'S LIABILITY

        The SELLER shall have no obligation and/or liabilities with respect to
defects discovered after the expiration of the period of guarantee specified
above.

        The SELLER shall be liable to the BUYER for defects and damages caused
by any of the defects specified in Section 1 of this Article provided that such
liability of the SELLER shall be limited to damage occasioned within the
guarantee period specified in Paragraph 1 above. The SELLER shall not be
obligated to repair, or to be liable for, damages to the VESSEL, or to any part
of the equipment thereof, due to ordinary wear and tear or caused by defects
other than those specified in Paragraph 1 above, nor shall there be any SELLER's
liability hereunder for defects in the VESSEL, or any part of the equipment
thereof, caused by fire or accidents at sea or elsewhere, or mismanagement,
accidents, negligence, or willful neglect, on the part of the BUYER, its
employees or agents including the VESSEL's officers, crew and passengers, or any
persons on or doing work on the VESSEL other than the SELLER, its employees,
agents or sub-contractors. Likewise, the SELLER shall not be liable for defects
in the VESSEL, or the equipment or any part thereof, due to repairs or
replacement which

of the Contract, the SELLER shall thereby and thereupon be released of all

provided for in this Article IX) including without limitation, any
responsibility or liability for defective workmanship, materials or equipment,
design or in respect of any other defects whatsoever and any loss or damage
resulting from any act, omission or default of the SELLER. Neither CSTC nor the
BUILDER shall, in any circumstances, be liable for any consequential loss or
special loss, or expenses arising from any cause whatsoever including, without
limitation, loss of time, loss of profit or earnings or demurrage directly from
any commitments of the BUYER in connection with the VESSEL other than pursuant
to the express terms of this Contract.

        The Guarantee provided in this Article and the obligations and the
liabilities of the SELLER hereunder are exclusive and in lieu of and the BUYER
hereby waives all other remedies, warranties,guarantees or liabilities, express
or implied, arising by Law or otherwise (including without limitation any
obligations of the SELLER with respect to fitness, merchantability and
consequential damages) or whether or not occasioned by the SELLER's negligence.
This guarantee shall not be extended, altered or varied except by a written
instrument signed by the duly authorized representatives of the SELLER, and the
BUYER.

5.      GUARANTEE ENGINEER

        The BUILDER shall appoint one guarantee engineer (the "Guarantee
Engineer") to serve the VESSEL as the BUILDER's representative for a period of
six (6) months from the delivery of the VESSEL. The BUYER and its employees
shall give such Guarantee Engineer full co-operation in carrying out his duties
as the representative of the BUILDER on board the VESSEL. The BUYER shall accord
the Guarantee Engineer(s) the treatment comparable to the VESSEL's Chief
Engineer, and shall provide him/them with accommodation and subsistence at no
cost to the BUILDER and/or the Guarantee Engineer.

        The BUYER shall pay to the Guarantee Engineer the sum of United States

limited to all costs of labor and/or prices paid or to be paid by the SELLER for

        whatsoever prior to acceptance and delivery thereof by the BUYER and in
        the further event that such damage shall not constitute an actual or a
        constructive total loss of the VESSEL, the SELLER shall apply the amount
        recovered under the insurance policy referred to in Section 1 of this
        Article to the repair of such damage satisfactory to the Classification
        Society and other institutions or authorities as described in the

                  other terms of this Contract including the Contract Price as
                  may be necessary for the completion of such reconstruction; or

                          (ii) If due to whatever reasons the parties fail to
                  agree on the above, then the BUYER shall deliver a written
                  notice of rejection to SELLER and the SELLER shall refund

                                                   Shipbuilding Contract H2246

        Should any dispute of any nature arise in respect of this Contract, its
performance or interpretation which is not decided in accordance with Article
XIII, Section 2 below, such dispute shall be settled by arbitration in London,
England in accordance with the rules of the London Maritime Arbitrators
Association Inc. and otherwise in accordance with the provisions of the Laws of
England. The party who desires arbitration of any such dispute shall give
written notice to the other party. The notice shall state the name and address
of the arbitrator whom it appoints and describe the specific nature of the
particular dispute. Such notice shall be sent by registered air mail and shall
be addressed in the manner set forth in Article XIX, and the other party shall,
within thirty (30) days following the receipt of said notice, give written
notice to the party requesting the arbitration as to the name and address of the
arbitrator whom it appoints, which notice shall be sent by registered air mail
and shall be addressed in the manner set forth in Article XIX, provided that if
the other party should fail to so appoint its arbitrator, the arbitrator
appointed by the party desiring the arbitration may proceed with the arbitration
hearing and issue an award. Otherwise the two arbitrators so chosen shall select
a third arbitrator. The applicable law of England on all matters at issue shall
apply. A judgement based upon the decision of the majority of the arbitrators or
the sole arbitrator, as the case may be, may be entered in the appropriate court
of any country having jurisdiction of either party. The arbitrators shall also
decide which party, or the extent to which each party, shall pay costs of
arbitration. Unless and to the extent otherwise determined by the arbitrator(s),
reference to arbitration shall not relieve the BUILDER of its obligation
diligently to proceed with the construction, completion and delivery of the
VESSEL, but the majority of the arbitrators or the sole arbitrator, as the case
may be, shall decide the extent to which the Delivery Date shall be extended by
virtue of the dispute having been referred to arbitration.

2.      ALTERNATIVE ARBITRATION BY AGREEMENT

        Notwithstanding the preceding provisions of this Article, it is
recognized that in the event of any dispute or difference of opinion arising in
regard to the construction of the VESSEL, her machinery and equipment, or
concerning the quality of materials or workmanship thereof or thereon, such
dispute may be referred to the Classification Society upon mutual agreement of
the parties hereto. In such case, the opinion of the Classification Society
shall be final and binding on the parties hereto.

3.      NOTICE OF AWARD

        Notice of any award shall immediately be given in writing or by telex
confirmed in writing to the SELLER and the BUYER.

Dear Sirs:

At the request of China Shipbuilding Trading Company, Limited ("CSTC") and
Jiangnan Shipyard (the "Builder" and, together with CSTC, the "SELLER") and in
consideration of Navigator Holdings PLC (the "BUYER") agreeing to pay SELLER the
installments of the contract price (the "Contract Price") pursuant to the
Amended and Restated Shipbuilding Contract dated the 26th day of June, 1997, as
amended, supplemented or otherwise modified from time to time (hereinafter
called the "Contract") made by and between the BUYER and the SELLER for the
construction of one (1) 22,000 cubic meter liquefied ethylene gas carrier having
Hull No. 2246 (hereinafter called the "VESSEL"), The Export Import Bank of China
the "Bank") the undersigned, do guarantee the payment (and not merely the
collectability of the same) to the BUYER by the SELLER immediately upon demand
of an amount up to but not exceeding a total amount as set forth in Schedule 1
hereto (calculated in accordance with the immediately following paragraph),
together with simple interest thereon calculated at the rate of ten percent
(10.0%) per annum on the basis of a 360 day year from and including the date of
receipt of demand to but not including the date of remittance by telegraphic
transfer of such refund.

Subject to BUYER making installment payments in accordance with Article II of
the Contract, the amount of this Guarantee will be automatically increased
during the term of this Guarantee and shall be equal to the sum of: (i) the
amount set forth on Schedule 1 hereto calculated as of the first day of the

                                                   Shipbuilding Contract H2246

Date of Rejection occurs; and (ii) an amount equal to the product of (X) the
difference between (1) the amount set forth on Schedule 1 hereto calculated as
of the first day of the calendar month immediately succeeding the month in which
the Date of Rejection occurs and (2) the amount set forth on Schedule 1 hereto
as of the first day of the month in which the Date of Rejection of the vessel
under the Contract occurs and (y) a fraction the numerator of which is numeric
day of the month of the date on which the Refund Amount (as hereinafter defined)
is actually paid and the denominator of which is 30 (collectively, the "Refund
Amount").

BUYER's right to demand payment under this Guarantee shall become effective on
the earlier to occur of (i) April 1, 2001, (ii) the date on which the SELLER
fails to pay any liquidated damages payable to BUYER as provided in Section 1(a)
of Article III of the Contract, (iii) upon the cancellation, termination or
rescission of the Contract by the BUYER in accordance with the terms of Contract
as set forth in Article III, 1(a), 2(c), 3(c), 4(c), 5(c), Article X, Article
XII 2(b), or Article XVI (b) or (c), or (iv) the insolvency or bankruptcy of
BUILDER.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to us by the BUYER.

Payment under this Guarantee is available at the counters of ______________ Bank
against presentation of the BUYER's signed statement issued in the form attached
hereto as Appendix A ("Notice of Demand"). If the Notice of Demand is received
by the Bank by 12:00 noon local time on a banking day, the Bank shall pay the
Refund Amount (plus interest thereon) in immediately available funds within ten
(10) banking days. If the Notice of Demand is received by the Bank after 12:00
noon local time on a banking day, the Bank shall pay the Refund Amount (plus
interest thereon) in immediately available funds within eleven (11) banking
days.

This Guarantee is available for one payment only, whether for the full amount
hereof or any part thereof, as may be demanded by the BUYER. In the event that
the BUYER's demand is for a lesser amount than the amount of this Guarantee, the
interest payable will be calculated on the amount of the BUYER's demand and not
on the amount of this Guarantee.

We agree that this Guarantee shall be a continuing guarantee and (i) shall not
be impaired or discharged by the granting of time or any other indulgence to the
SELLER, or any other forbearance (whether as to payment, time, performance, or
otherwise) which might, but for this provision, have any such effect; (ii) shall
not be conditioned or contingent upon the BUYER's pursuit of any remedy that it
has against the SELLER;

and (iii) shall be unconditional irrespective of any other circumstance that
might otherwise constitute a legal or equitable discharge of a surety or
guarantor under applicable law, and we hereby waive any and all rights (whether
by counterclaim, set off or otherwise) and defenses at law or in equity that may
be available to us by reason of such circumstance.

This Guarantee shall become effective from the time of the actual receipt of the
first installment by the SELLER from the BUYER under the Contract and the Refund
Amount payable under this Guarantee shall correspond to the total installment
payments actually made by the BUYER to the SELLER from time to time under the
Contract prior to the delivery of the VESSEL including applicable interest.

This Guarantee shall expire and become null and void on the earlier to occur of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
the Bank of either a copy of the Protocol of Delivery and Acceptance of the
VESSEL, purportedly signed by the BUYER and the SELLER and issued in the form
attached hereto as Appendix B or a copy of the Certificate of Completion of the
Vessel signed by the respective parties thereto in the form attached hereto as
Appendix C; or (iii) 5:00 p.m. New York time on May 1, 2001, in any such case
this Guarantee shall be returned to us; provided, the Bank further agrees that
its obligations hereunder shall continue to be effective or reinstated, as the
case may be, if at any time any payment, or any part thereof, made by the SELLER
is rescinded or must otherwise be restored by the BUYER upon the bankruptcy or
reorganization of the SELLER.

Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER confirmed by an arbitrator stating that the BUYER's
claim to cancel the Contract or the BUYER's claim for refundment thereunder has
been disputed and referred to arbitration in accordance with the provisions of
the Contract, the period of validity of this Guarantee shall be extended until
thirty (30) days after the final award shall be rendered in the arbitration and
a copy thereof acknowledged by the arbitrators. In such case, this Guarantee
shall not be available unless and until such acknowledged copy of the final
award in the Arbitration justifying the BUYER's claim is presented to us;
subject to any appeal of such final award which may be permitted under English
law; provided the Refund Amount shall be adjusted to reflect the delay resulting
from such arbitration and shall be calculated in accordance with Schedule 1
hereto to the date payment is actually made.

Dear Sirs:

At the request of Tractebel Gas Engineering GmBH and in consideration of
Navigator Holdings, PLC (the "BUYER") agreeing to pay China Shipbuilding Trading
Company, Limited ("CSTC") and Jiangnan Shipyard (the "Builder" together with
CSTC collectively called the "SELLER") the installments of the contract price
(the "Contract Price") pursuant to the Amended and Restated Shipbuilding
Contracts dated the 26th day of June, 1997, as amended, supplemented or
otherwise modified from time to time (hereinafter called the "Contracts") made
by and between the BUYER and the SELLER for the construction of five (5) 22,000
cubic meter liquefied ethylene gas carriers having Hull Nos. 2245, 2246, 2247,
2248 and 2249 (hereinafter called the "VESSELS"), Generale de Banque (the
"Bank") guarantees the payment (and not merely the collectability of the same)
to the BUYER by the SELLER, immediately upon demand, of an amount up to but not
exceeding a total aggregate amount of United States Dollars Thirteen Million
Three Hundred Thousand (US$13,300,000) (the "Payment Amount"), if and when the
same or any part thereof become payable to BUYER from the SELLER under any
Contract or Contracts if any such contract or contracts are cancelled by the
BUYER in accordance with the terms (Article III, 1(a), 2(c), 3(c), 4(c), 5(c),
Article X, Article XII 2(b) and Article XVI(b) and (c)) of the Contracts (any a
"Cancellation Event"). This Performance Bond shall become effective upon payment
of the initial installment under each of the Contracts.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to the BANK by the BUYER.

Payment under this Performance Bond is available at the counters of
_______________ against presentation of the BUYER's signed statement issued in
the form attached hereto as Appendix A ("Notice of Demand"). The Notice of
Demand shall set forth the dollar amount to be paid to the

                                       C-1

<PAGE>



BUYER under this Performance Bond, which amount shall be based upon Schedule 1
attached hereto (the "Demand Amount") provided such Demand Amount shall not
exceed the Payment Amount. As to any date on which a Notice of Demand is
presented, the Demand Amount shall be equal to the amount set forth opposite the
calendar month in which such Notice of Demand is presented and under the column
heading specified in the Notice of Demand less the amount paid by the
Export-Import Bank of China under such Bank's Irrevocable Performance Bond dated
_______, 1997 (the "Ex-Im Performance Bond"). In addition, the BUYER's right to
demand payment as provided above is subject to delivery by BUYER to the Bank of
a copy of the notice of demand presented to the Export-Import Bank of China
under the Ex-Im Performance Bond in the amount of US$26,700,000 and evidence
that such amount has been paid.

If the Notice of Demand is received by the Bank by 12:00 noon local time on a
business day, the Bank shall pay the Demand Amount in immediately available
funds on the same business day. If the Notice of Demand is received by the Bank
after 12:00 noon local time on a business day, the Bank shall pay the Demand
Amount in immediately available funds on the next succeeding business day.

The right of the BUYER to demand payment under this Performance Bond shall
become effective on the earlier to occur of (i) April 1, 2001, (ii) the date on
which the SELLER fails to pay any liquidated damages payable to BUYER as
provided in Section 1(a) of Article III of the Contracts, (iii) the occurrence
of a Cancellation Event or (iv) the bankruptcy or insolvency of the Builder.

This Performance Bond is available for one payment only, whether for the full
amount hereof or any part thereof, as may be demanded by the BUYER.

We agree that this Performance Bond shall be a continuing guarantee and (i)
shall not be impaired or discharged by the granting of time or any other
indulgence to the SELLER, or any other forbearance (whether as to payment, time,
performance, or otherwise) which might, but for this provision, have any such
effect; (ii) shall not be conditioned or contingent upon the BUYER's pursuit of
any remedy that it has against the SELLER; and (iii) shall be unconditional
irrespective of any other circumstance that might otherwise constitute a legal
or equitable discharge of a surety or guarantor under applicable law, and we
hereby waive any and all rights (whether by counterclaim, set off or otherwise)
and defenses at law or in equity that may be available to us by reason of such
circumstance.

This Performance Bond shall expire and become null and void on the earlier of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
Bank of a copy of the Protocol of Acceptance and Delivery and/or Certificates of
Completion for each of the five (5) VESSELs in the form of Appendix B or
Appendix C to this Performance Bond; and (iii) 5:00 p.m. New York time on May 1,
2001, in any such case this Performance Bond shall be returned to us; provided,
the Bank further agrees that its obligations hereunder shall continue to be
effective or
reinstated, as the case may be, if at any time any payment, or any part thereof,
made by the SELLER is rescinded or must otherwise be restored by the BUYER upon
the bankruptcy or reorganization of the SELLER.



Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER confirmed by an arbitrator stating that the BUYER's
claim to cancel the Contracts or the BUYER's claim for refundment thereunder has
been disputed and referred to arbitration in accordance with the provisions of
the Contract, the period of validity of this Performance Bond shall be extended
until thirty (30) days after the final award shall be rendered in the
arbitration and a copy thereof acknowledged by the arbitrators. In such case,
this Performance Bond shall not be available unless and until such acknowledged
copy of the final award in the Arbitration justifying the BUYER's claim is
presented to us; subject to any appeal of such final award which may be
permitted under English law.

This Performance Bond is governed by and enforced and construed in accordance
with the laws of England.

                  Rejection occurs and (2) the amount set forth on Schedule 3
                  hereto as of the first day of the month in which the Date of
                  Rejection occurs and (y) a fraction the numerator of which is
                  the numeric day of the month of the Date of Rejection and the
                  denominator of which is 30.

If the amount as calculated above is not paid on the Date of Rejection there
shall be added to such amount interest at the rate of ten percent (10%) per
annum from and including the Date of Rejection to but not including the date
such amount is paid. Such refunds by the SELLER to the BUYER shall forthwith
discharge all obligations, duties, and liabilities of each of the parties hereto
to the other under this Contract. Any and all refunds made to the BUYER under
this Article II, Section 7 shall be made in United States Dollars. Throughout
this Contract, whenever interest is due on any amounts to be paid or refunded by
either party, said interest shall be calculated as simple interest, based on the
actual number of days divided by 360.

        For purposes of this Section 7(a) Date of Rejection means the date on
which written notice of rejection, cancellation or rescission is delivered by
BUYER to SELLER.

        All refunds made by the SELLER to the BUYER under this contract shall be
paid in United States Dollars by telegraphic transfer to the BUYER's account or
its assignee's account as set forth in a written notice to the SELLER from such
party.

        (b) Upon the payment of the first installment and the delivery of the
Trustee's Commitment Letter in the form of Exhibit E hereto, the SELLER shall,
at its cost, furnish the BUYER with (i) an Irrevocable Letter of Guarantee given

                                   ARTICLE III
                        ADJUSTMENT OF THE CONTRACT PRICE

        The Contract Price of the VESSEL as provided for in Schedule 1 shall be
subject to adjustments as hereinafter set forth. It is hereby understood by both
parties that any reduction of the Contract Price is by way of liquidated damages
and not by way of penalty.

1.      DELIVERY

        (a)       Delayed Delivery Price Adjustment:

                          (i) For purposes of this Contract the Original
                  Delivery Date for the Vessel shall mean the date set forth in
                  Article VII, Section (1) below.

                          (ii) If the Delivery is not made on the Original
                  Delivery Date (subject to a Permissible Delay as defined
                  below), the SELLER shall pay the BUYER, as liquidated damages
                  (not as penalty), the amount of $10,000 for each calendar day
                  for the first ninety (90) calendar days of

                                                     Shipbuilding Contract H2247

                  delay beyond the Extended Delivery Date (as hereinafter
                  defined) and the amount of $13,500 for each calendar day of
                  delay thereafter up to and including the 210th day from the
                  Original Delivery Date ("Original Delay Period"). Liquidated
                  damages calculated with respect to the Original Delay Period
                  shall be recovered by the BUYER through a reduction in the
                  Fifth Installment payable by the BUYER to the SELLER in an
                  amount equal to such Liquidated Damages.

                          (iii) If delivery of the VESSEL is delayed for any
                  reason beyond the Original Delay Period, the Builder may elect
                  to further postpone delivery of the Vessel beyond the Original
                  Delay Period until March 31, 2001 provided SELLER pays
                  liquidated damages monthly in advance to the BUYER at the rate
                  of US$18,000 per day from the end of the Original Delay Period
                  to a date which is 6 months thereafter (the "First Penalty
                  Date"), and US$20,000 per day from the First Penalty Date to
                  the date which is 6 months thereafter (the "Second Penalty
                  Date"), and US$22,000 per day from the Second Penalty Date
                  until March 31, 2001. If the SELLER fails to make any
                  liquidated damages payment, BUYER, in its sole discretion, may
                  either (i) reject the VESSEL or (ii) waive its right to
                  receive the payment of liquidated damages and further reduce
                  the Contract Price for the VESSEL by an amount equal to the
                  liquidated damages which would have been payable.
                  Notwithstanding any other provision contained in this Contract
                  to the contrary, this Contract shall be deemed rescinded on
                  April 1, 2001 and the Buyer shall be entitled to receive the
                  amounts set forth in Article II, Section 7(a) above.

                          Any waiver by the BUYER of its right to receive
                  liquidated damages monthly in advance is not a waiver of the
                  BUYER's right to (a) demand payment of such liquidated damages
                  at a later date, (b) demand monthly advances as to Liquidated
                  Damages for any subsequent months of delay or (c) reject the
                  VESSEL at such later date if liquidated damages are not paid
                  upon demand. The liquidated damages calculated pursuant to
                  this paragraph are in addition to the reduction in the fifth
                  installment of the Contract Price as calculated pursuant to
                  (ii) above for the Original Delay Period.

                          (iv) In the event that the BUYER elects to reject the
                  VESSEL as allowed under this Article III, Section 1(a), the
                  SELLER shall immediately repay to the BUYER the amounts set
                  forth in Article II, Section 7, whereupon this Contract shall
                  terminate and such payment shall

                  the VESSEL shall not be deemed delayed and the Contract Price
                  shall not be reduced when and if the Original Delivery Date of

                  inaction on the part of SELLER; provided such Permissible
                  Delay shall be subject to the following provisions:

                                   (B) For purposes of this Contract the
                          Extended Delivery Date for a Vessel shall mean the
                          Original Delivery Date plus the Permissible Delay for
                          such Vessel,

                                   (C) The aggregated Permissible Delay for the 
                          Vessel and the Sister Vessels shall not exceed 150

                          (A) above, SELLER shall have the right in its sole
                          discretion to designate either the Vessel or any
                          Sister Vessel as to which Vessel will be subject to a
                          Permissible Delay.

        (b)       Early Delivery Price Adjustment:

                          If the SELLER notifies the BUYER by facsimile that the
                  delivery of the VESSEL shall be made earlier than the Original

                  planned delivery date, a certain amount of bonus shall be
                  given by the BUYER to the SELLER as follows:

                          In the event that the delivery shall be made earlier
                  than the Original Delivery Date and notice is properly given,
                  then a bonus shall be added to the Contract Price at a rate of
                  United States Dollars Thirteen Thousand (US$13,000) per day
                  for each full day earlier than the Original Delivery Date.

                          The total increase of the Contract Price for the
                  earlier delivery shall be added to the fifth installment of

                                                     Shipbuilding Contract H2247

        Unless notification is given to the BUILDER by the Supervisor or the
BUYER of approval or disapproval of any plans and drawings within the above
designated period of time for each case, the said plans and drawings shall be
deemed to have been automatically approved.

        The plans and drawings approved by the BUYER or Supervisor shall be
final, and any alteration thereof shall be regarded as modification specified in
Article V of this Contract.

3.      SUPERVISION AND INSPECTION BY THE SUPERVISOR

        The necessary inspection of the VESSEL, its machinery, equipment and
outfittings shall be carried out by the Classification Society, and/or
inspection team of the BUILDER throughout the entire period of construction in
order to ensure that the construction of the VESSEL is duly performed in
accordance with the Contract and Specifications.

        The Supervisor shall have, at all times until delivery of the VESSEL,
the right to attend tests according to the mutually agreed test list and inspect
the VESSEL, her engines, accessories and materials at the BUILDER's Shipyard,
its subcontractors or any other place where work is done or materials stored in
connection with the VESSEL. In the event that the Supervisor discovers any
construction or material or workmanship which does not or will not conform to
the requirements of this Contract and the Specifications, the Supervisor shall
promptly give the BUILDER a notice in writing as to such nonconformity, upon
receipt of which the BUILDER shall correct such nonconformity if the BUILDER
agrees with the BUYER. However the BUYER undertakes and assures the SELLER that
the Supervisor shall carry out his inspections in accordance with the agreed
inspection procedure and Schedule and usual shipbuilding practice and in a way
as to minimize any increase in building costs and delays in the construction of
the VESSEL.

        The BUILDER agrees to furnish, free of charge, the Supervisor with
office space, and other reasonable facilities according to BUILDER's practice
at, or in the immediate vicinity of the BUILDER's Shipyard, but the fees for the
international communication like telephone and telefax, etc. shall be borne by
the BUYER. At all times, during the construction of the VESSEL until delivery
thereof, the Supervisor shall be given free and ready access to the VESSEL, her
engines and accessories, and to any other place where the work is being done, or
the materials are being processed or stored, in connection with the construction
of the VESSEL, including the yards, workshops, stores of the BUILDER, and the
premises of subcontractors of the BUILDER, who are

                                                     Shipbuilding Contract H2247

doing work, or storing materials in connection with the VESSEL's construction.
The travel expenses for the said access to SELLER's subcontractors outside of
Shanghai shall be at BUYER's account. The transportation within Shanghai shall
be provided to the Supervisor by the SELLER.

4.      LIABILITY OF THE SELLER

        The Supervisor engaged by the BUYER under this Contract shall at all
times be deemed to be in the employment of the BUYER. The SELLER shall be under
no liability whatsoever to the BUYER, or to the Supervisor or the BUYER's
employees or agents for personal injuries, including death, during the time when
they, or any of them, are on the VESSEL, or within the premises of either the
SELLER or its subcontractors, or are otherwise engaged in and about the
construction of the VESSEL, unless, however, such personal injuries, including
death, were caused by negligence of the SELLER, or of any of the SELLER's
employees or agents or subcontractors of the SELLER. Nor shall the SELLER be
under any liability whatsoever to the BUYER for damage to, or loss or
destruction of property in China of the BUYER or of the Supervisor, or of the
BUYER's employees or agents, unless such damage, loss or destruction was caused
by negligence of the SELLER, or of any of the employees, or agents or
subcontractors of the SELLER.

5.      SALARIES AND EXPENSES

        All salaries and expenses of the Supervisor, or any other employees
employed by the BUYER under this Article, shall be for the BUYER's account.

6.      REPLACEMENT OF SUPERVISOR

        The SELLER has the right to request the BUYER in writing to replace any
of the Supervisor who is deemed unsuitable and unsatisfactory for the proper
progress of the VESSEL's construction together with reasons. The BUYER shall
investigate the situation by sending its representative to the BUILDER's yard,
if necessary, and if the BUYER considers that such SELLER's request is
justified, the BUYER shall effect the replacement as soon as conveniently
arrangable.

                                    ARTICLE V
                        MODIFICATION, CHANGES AND EXTRAS

1.      HOW EFFECTED

        The Specifications in accordance with which the VESSEL is constructed,
may be modified and/or changed at any time hereafter by written agreement of the
parties hereto, provided that such modifications and/or changes or an
accumulation thereof will not, in the BUILDER's reasonable judgment, adversely
affect the BUILDER's other commitments and provided further that the BUYER shall
assent to adjustment of the Contract Price, time of delivery of the VESSEL and
other terms of this Contract, if any, as hereinafter provided. Subject to the
above, the SELLER hereby agree to exert their best efforts to accommodate such
reasonable requests by the BUYER so that the said changes and/or modifications
may be made at a reasonable cost and within the shortest period of time which is
reasonable and possible. Any such agreement for modifications and/or changes
shall include an agreement as to the increase or decrease, if any, in the
Contract Price of the VESSEL together with an agreement as to any extension or
reduction in the time of delivery, providing to the SELLER additional securities
satisfactory to the SELLER, or any other alterations in this Contract, or the
Specifications occasioned by such modifications and/or changes. The
aforementioned agreement to modify and/or to change the Specifications may be
effected by an exchange of duly authenticated letters, telex and telefaxes,
manifesting such agreement. The letters, telexes as well as telefaxes exchanged
by the parties hereto pursuant to the foregoing shall constitute an amendment of
the Specifications under which the VESSEL shall be built, and such letters,
telexes and telefaxes shall be deemed to be incorporated into this Contract and
the Specifications by reference and

                                                            Amended and Restated
                                                     Shipbuilding Contract H2247

made a part hereof. Upon consummation of the agreement to modify and/or to
change the Specifications, the SELLER shall alter the construction of the VESSEL
in accordance therewith, including any additions to, or deductions from, the
work to be performed in connection with such construction. If due to whatever
reasons, the parties hereto shall fail to agree on the adjustment of the
Contract Price or extension of time of delivery or providing additional security
to the SELLER or modification of any terms of this Contract which are
necessitated by such modifications and/or changes, then the SELLER shall have no
obligation to comply with the BUYER's request for any modification and/or
changes.

2.      CHANGES IN RULES AND REGULATIONS

        (a) If, after the Effective Date, any requirements as to the rules and
regulations as specified in this Contract and the Specifications to which the
construction of the VESSEL is required to conform, are altered or changed by the
Classification Society or the other regulatory bodies authorized to make such
alterations or changes, the SELLER and/or the BUYER, upon receipt of the notice
thereof, shall transmit such information in full to each other in writing,
whereupon within twenty one (21) days after receipt of the said notice by the
BUYER from the SELLER or vice versa, the BUYER shall instruct the SELLER in
writing as to the alterations or changes, if any, to be made in the VESSEL which
the BUYER, in its sole discretion, shall decide. The SELLER shall promptly
comply with such alterations or changes, if any in the construction of the
VESSEL, provided that the BUYER shall first agree:

                  (i) As to any increase or decrease in the guaranteed
        deadweight and/or cargo tank capacity and for speed of the VESSEL, if
        such compliance results in increased or reduced deadweight and/or cargo
        tank capacity and speed; and/or

                  (ii) As to any other alterations in the terms of this Contract
        or of Specifications or both, if such compliance makes such alterations
        of the terms necessary.

        Agreement as to such alterations or changes under this Paragraph shall
be made in the same manner as provided above for modifications and/or changes of
the Specifications and/or Plans.

        (b)  If, due to whatever reasons, the parties shall fail to agree on the
increase or decrease of the guaranteed speed, deadweight and cargo tank 
capacity,

                                                     Shipbuilding Contract H2247

or any alteration of the terms of this Contract, if any, then the SELLER shall
be entitled to proceed with the construction of the VESSEL in accordance with,
and the BUYER shall continue to be bound by, the terms of this Contract and
Specifications without making any such alterations or changes.

        (c) The BUYER and the SELLER hereby agree to make best efforts to avoid
the application and/or minimize the effect of any change in the rules and
regulations of the Classification Society as to the Specifications. If the BUYER
and the SELLER are unsuccessful in avoiding the application of such change in
rules and regulations, then the SELLER shall effect any modifications and/or
changes in Specifications without adjustment to the Contract Price and the BUYER
shall grant to the SELLER the right to extend the Delivery Date (if necessary)
for a maximum period of up to twelve (12) days.

3.      SUBSTITUTION OF MATERIALS AND/OR EQUIPMENT

        In the event that any of the materials and/or equipment required by the
Specifications or otherwise under this Contract for the construction of the
VESSEL cannot be procured in time to effect delivery of the VESSEL, the SELLER
may, provided the SELLER shall provide adequate evidence and the BUYER so agrees
in writing, supply other materials and/or equipment of the equivalent quality,
capable of meeting the requirements of the Classification Society and of the
rules, regulations, requirements and recommendations with which the construction
of the VESSEL must comply.

4.      BUYER'S SUPPLIED ITEMS

        The BUYER shall deliver to the SELLER at its shipyard the items as
specified in the Specifications which the BUYER shall supply for its own account
(the "BUYER's Supplies") by the time designated by the SELLER.

        The delay in the delivery or the failure to deliver by the BUYER of any
BUYER's Supplies within the time specified shall not extend the Delivery Date.

        However, if the delay in delivery of the BUYER's Supplies should exceed
fifteen (15) days, the SELLER shall be entitled to proceed with construction of
the VESSEL without installation of such items in or onto the VESSEL and the
BUYER shall accept the VESSEL so completed.

                                                     Shipbuilding Contract H2247

        The BUILDER shall be responsible for storing and handling of the BUYER's
Supplies as specified in the Specifications after delivery to the BUILDER and
shall install them on board the VESSEL at the BUILDER's expenses.

        Upon arrival of such shipment of the BUYER's Supplies, both parties
shall undertake an joint unpacking inspection. If any damaged BUYER's supplies
are found to be unsuitable for installation, the BUILDER shall be entitled to
refuse to accept the BUYER's Supplies.

                                   ARTICLE VI
                                     TRIALS

1.      NOTICE

        The BUYER and the Supervisor shall receive from the SELLER at least
thirty (30) days notice in advance and seven (7) days definite notice in advance
in writing by telex or telefax, of the time and place of the VESSEL's sea trial
as described in the Specifications (hereinafter referred to as "the Trial Run")
and the BUYER and the Supervisor shall promptly acknowledge receipt of such
notice. The BUYER's representatives and/or the Supervisor shall be on board the
VESSEL to witness such Trial Run, and to check upon the performance of the
VESSEL during the same. Failure of the BUYER's representatives to be present at
the Trial Run of the VESSEL, after due notice to the BUYER and the Supervisor as
provided above, shall have the effect to extend the date for delivery of the
VESSEL by the period of delay caused by such failure to be present. However, if
the Trial Run is delayed more than five (5) days by reason of the failure of the
BUYER's representatives to be present after receipt of due notice as provided
above (other than due to the failure by the BUYER's representative to obtain a
visa to enter China), then in such event, the BUYER shall be deemed to have
waived its right to have its representatives on board the VESSEL during the
Trial Run, and the BUILDER may conduct such Trial Run without the BUYER's
representatives being present, and in such case the BUYER shall be obliged to
accept the VESSEL on the basis of a certificate jointly signed by the BUILDER
and the Classification Society certifying that the VESSEL, after Trial Run
subject to minor alterations and corrections as provided in this Article, if
any, is found to conform to the Contract and Specifications and is satisfactory
in all respects. The SELLER hereby warrants that the necessary visa for the
BUYER's representatives to enter China will be issued in order on demand and
without delay otherwise the Trial Run shall be postponed until the BUYER's
representatives have arrived at the BUILDER's Shipyard. However, should the
nationalities and other personal particulars of the BUYER's representatives be
not acceptable to the SELLER in accordance with its best

                                                     Shipbuilding Contract H2247

understanding of the relevant rules, regulations and/or Laws of the People's
Republic of China then prevailing, then the SELLER shall so notify the BUYER and
the BUYER shall endeavor to effect the replacement of all or any of such
representatives. The Delivery Date as stipulated in Article VII hereof shall not
be extended by any delays caused by the BUYER's replacement of its
representatives pursuant to the SELLER's request. In the event of unfavorable
weather on the date scheduled for the Trial Run, the same shall take place on
the first available day thereafter that the weather conditions permit. The
parties hereto recognize that the weather conditions in Chinese waters in which
the Trial Run is to take place are such that great changes in weather may arise
momentarily and without warning and, therefore, it is agreed that if during the
Trial Run of the VESSEL, the weather should suddenly become unfavorable, as
would have precluded the continuance of the Trial Run, the Trial Run of the
VESSEL shall be discontinued and postponed until the first favorable day next
following, unless the BUYER assents in writing by telex or telefax of its
acceptance of the VESSEL on the basis of the Trial Run made prior to such sudden
change in weather conditions. In the event that the Trial Run is postponed
because of unfavorable weather conditions, the Delivery Date shall not be
extended other than pursuant to Article VIII hereof.

2.      HOW CONDUCTED

        (a) All expenses in connection with Trial Run of the VESSEL are to be
for the account of the BUILDER, who, during the Trial Run and when subjecting
the VESSEL to Trial Run, is to provide, at its own expense, the necessary crew
to comply with conditions of safe navigation. The Trial Run shall be conducted
in the manner prescribed in the Specifications and shall prove fulfillment of
the performance required for the Trial Run as set forth in the Specifications.

        The course of Trial Run shall be determined by the BUILDER and shall be
conducted within the trial waters equipped with speed measuring facilities.

        (b) The BUILDER shall provide the VESSEL with the required quantities of
water and fuel oil with exception of lubrication oil, hydraulic oil and greases
which shall be supplied by the BUYER according to the BUILDER's schedule which
shall be forwarded to the BUYER by the BUILDER for the conduct of the Trial Run
or Trial Runs as prescribed in the Specifications. The fuel oil supplied by the
SELLER, and lubricating oil, hydraulic oil and greases supplied by the BUYER
shall be in accordance with the applicable engine Specifications, and the cost
of the quantities of water, fuel oil, lubricating oil, hydraulic oil and greases
consumed during the Trial Run or Trial Runs shall be for the account of the
BUILDER.

3.      TRIAL LOAD DRAFT

        In addition to the supplies provided by the BUYER in accordance with
sub-paragraph (b) of the preceding Section 2 of this Article VI, the BUILDER
shall provide the VESSEL with the required quantity of fresh water and other
stores necessary for the conduct of the Trial Run. The necessary ballast (fresh
water, sea water or any other ballast as may be required) to bring the VESSEL to
the trial load draft as specified in the Specifications, shall be for the
BUILDER's account.

4.      METHOD OF ACCEPTANCE OR REJECTION

        (a) Upon notification of the BUILDER of the completion of the Trial Run
of the VESSEL attached with the trial result, the BUYER or the BUYER's
Supervisor shall within six (6) business days thereafter, notify the BUILDER in
writing by telex or telefax of its acceptance of the VESSEL or of its rejection
of the VESSEL together with the reasons therefor.

        (b) However, should the result of the Trial Run indicate that the VESSEL
or any part thereof including its equipment does not conform to the requirements
of this Contract and Specifications the BUILDER shall investigate with the
Supervisor the cause of failure and shall take proper steps to remedy the same
and shall make whatever corrections and alterations and/or re-Trial Run or Trial
Runs as may be necessary without extra cost to the BUYER, and upon notification
by the BUILDER of completion of such alterations or corrections and/or re-trial
or re-trials, the BUYER shall, within six (6) business days thereafter, notify
the SELLER in writing by telex or telefax of its acceptance of the VESSEL or of
its rejection of the VESSEL together with the reason therefor on the basis of
the alterations and corrections and/or re-Trial Run or re-Trial Runs by the
BUILDER.

telex or telefax of its acceptance or rejection of the VESSEL together with the
reason therefor within six (6) business days period as provided for in the above
sub-paragraphs (a) and (b), the BUYER shall be deemed to have accepted the
VESSEL.

        (d) Any dispute arising among the parties hereto as to the result of any
Trial Run or further tests or trials, as the case, may be, of the VESSEL shall
be referred to the Classification Society as provided in Article XIII Section 2
hereof.

        (e) Nothing herein shall preclude the BUYER from accepting the VESSEL
with its qualifications and/or remarks following the Trial Run and/or further
tests or trials as

                                                     Shipbuilding Contract H2247

aforesaid and the SELLER shall be obliged to comply with and/or remove such
qualifications and/or remarks (if such qualifications and/or remarks are
acceptable to the SELLER) at the time before effecting delivery of the VESSEL to
the BUYER under this Contract.

5.      DISPOSITION OF SURPLUS CONSUMABLE STORES

        Should any amount of fuel oil, fresh water, or other unbroached
consumable stores furnished by the BUILDER for the Trial Run or Trial Runs
remain on board the VESSEL at the time of acceptance thereof by the BUYER, the
BUYER agrees to buy the same from the SELLER at the purchasing price at the port
of delivery thereof, and payment by the BUYER shall be effected, together with
the payment of the fifth installment, as provided in Article II, Section 4 of
this Contract.

        The BUYER shall supply lubricating oil, hydraulic oil and greases for
the purpose of Trial Runs at its own expenses and the SELLER will reimburse for
the amount of lubricating oil, hydraulic oil and greases actually consumed for
the said Trial Run or Trial Runs at the purchasing price incurred by the BUYER
and payment by the SELLER shall be effected by deducting from the fifth
installment the amount of such payment as provided in Article II, Section 4 of
this Contract.

6.      EFFECT OF ACCEPTANCE

        The BUYER's acceptance of the VESSEL in writing by telex or telefax
notification sent to the SELLER, in accordance with the provisions set out
above, shall be final and binding so far as conformity of the VESSEL to this
Contract and the Specifications is concerned, and shall preclude the BUYER from
refusing Delivery (as defined below) by the SELLER of the VESSEL, as hereinafter
provided, if the SELLER complies with all other procedural requirements for
delivery as hereinafter set forth.

                    DELAYS AND EXTENSION OF TIME FOR DELIVERY

1.      CAUSE OF DELAY

        If, at any time before actual Delivery, either the construction of the
VESSEL, or any performance required hereunder as a prerequisite of delivery of
the VESSEL, is delayed due to war, blockade, revolution, insurrection,
mobilization, civil commotions, riots, strikes, sabotage, lockouts, local
temperature higher than 35 degree centigrade, Acts of God or the public enemy,
plague or other epidemics, quarantines, prolonged failure or restriction of
electric current from an outside source, freight embargoes, if

any, earthquakes, tidal waves, typhoons, hurricanes, storms or other causes
beyond the control of the BUILDER or of its sub-contractors, as the case may be,
or by force majeure of any description, whether of the nature indicated by the
forgoing or not, or by destruction of the BUILDER or works of the BUILDER or its
sub-contractors, or of the VESSEL or any part thereof, by fire, flood, or other
causes beyond the control of the SELLER or its sub-contractors as the case may
be, then, in the event of delay due to the happening of any of the
aforementioned contingencies, the SELLER shall not be liable for such delay and
the time for delivery of the VESSEL under this Contract shall be extended
without any reduction in the Contract Price subject nevertheless to (i) the
provisions of Section 1(a) of Article III as to reduction in Contract Price,
(ii) the BUYER's right of termination under Section 1(a) of Article III and
(iii) all relevant provisions of this Contract which authorize and permit
extension of the time of delivery of the VESSEL.

2.      NOTICE OF DELAY

        Within fourteen (14) days from the date of commencement of any delay on
account of which the SELLER claims that it is entitled under this Contract to an
extension of the time for delivery of the VESSEL, the SELLER shall advise the
BUYER in writing by telex or telefax of the date such delay commenced, and
reasons therefor.

        Likewise within fourteen (14) days after such delay ends, the SELLER
shall advise the BUYER in writing by telex or telefax of the date such delay
ended, and also shall specify the maximum period of the time by which the date
for delivery of the VESSEL is extended by reason of such delay. Failure of the
BUYER to acknowledge the SELLER's notification of any claim for extension of the
Delivery Date within fourteen (14 ) days after receipt by the BUYER of such
notification, shall be deemed to be a waiver by the BUYER of its right to object
to such extension.

                               WARRANTY OF QUALITY

1.      GUARANTEE OF MATERIAL AND WORKMANSHIP

BUYER of the VESSEL, guarantees the VESSEL, her hull and machinery and all parts
and equipment thereof that are manufactured or furnished or supplied by the
SELLER and/or its sub-contractors under this Contract including material,
equipment (however excluding any parts for the VESSEL which have been supplied
by or on behalf of the

BUYER) against all defects which are due to defective materials, and/or poor
workmanship or failure to construct in conformity with the Specifications.

2.      NOTICE OF DEFECTS

        The BUYER shall notify the SELLER in writing by telex or telefax, as
promptly as possible, after discovery of any defect or deviations for which a
claim is made under this guarantee. The BUYER's written notice shall describe
the nature of the defect and the extent of the damage caused thereby. The SELLER
shall have no obligation under this guarantee for any defects discovered prior
to the expiry date of the guarantee, unless notice of such defects is received
by the SELLER not later than thirty (30) days after such expiry date. Telexed or
telefaxed advice with brief details explaining the nature of such defect and
extent of damage within thirty (30) days after such expiry date and that a claim
is forthcoming will be sufficient to comply with the requirements as to time.

3.      REMEDY OF DEFECTS

        The SELLER shall remedy at its expense any defect, against which the
VESSEL or any part of the equipment thereof is guaranteed under this Article by
making all necessary repairs and/or replacement. Such repairs and/or replacement
will be made by the SELLER.

        However, if it is impractical to make the repair by the SELLER, and if
forwarding by the SELLER of replacement part, and materials cannot be
accomplished without impairing or delaying the operation of the VESSEL, then, in
any such event, the BUYER shall cause the necessary repairs or replacements to
be made elsewhere at the discretion of the BUYER provided that the BUYER shall,
as soon as possible, give the SELLER notice in writing by telex or telefax of
the time and place such repairs will be made, provided always that the burden of
proof as to the necessity for such repairs and replacements shall rest with the
BUYER, and a written confirmation for such repairs or replacement shall be
obtained from the SELLER. Defects that affect the safety of the VESSEL or her
crew and/or constitute an emergency shall be repaired either by the crew or a
BUYER selected contractor in a manner reasonable under the circumstances without
the SELLER's prior approval and the SELLER shall be notified as to the nature
and extent of repairs as soon as possible after the repairs are undertaken and
such repair work will be subject to the mutual agreement between the parties. If
the VESSEL is not thereby delayed or her operation is not thereby delayed or
impaired, the SELLER shall have the right to verify the nature and extent of the
defects complained of by its own representative(s) or that of Classification
Society.

                                                     Shipbuilding Contract H2247

The SELLER shall, in such cases, promptly advise the BUYER, by telex or telefax,
after such examination has been completed, of its acceptance or rejection of the
defects as ones justifying theremedy under this Article. In all minor cases, the
Guarantee Engineer, as hereinafter provided for, will act for and on behalf of
the SELLER.

        In any circumstances, the SELLER shall immediately pay to the BUYER in
United States Dollars by telegraphic transfer the actual cost for such repairs
or replacements including forwarding charges, or at the average cost for making
similar repairs or replacements including forwarding charges as quoted by a
leading shipyard each in China, Singapore, Korea and Spain, whichever is lower:

        remedy under this Article, or

                  (b) If the SELLER neither accepts nor rejects the defects as
        above provided, nor requests arbitration within thirty (30) days after
        its receipt of the BUYER's notice of defects.

        Any dispute shall be referred to arbitration in accordance with the
provisions of Article XIII hereof.

employees or agents including the VESSEL's officers, crew and passengers, or any
persons on or doing work on the VESSEL other than the SELLER, its employees,
agents or sub-contractors. Likewise, the SELLER shall not be liable for defects

BUYER.

5.      GUARANTEE ENGINEER

        The BUILDER shall appoint one guarantee engineer (the "Guarantee

5.      SALE OF THE VESSEL

        (a) In the event of cancellation or rescission of this Contract as above
provided, the SELLER shall have full right and power either to complete or not
to complete the VESSEL as it deems fit and to sell the VESSEL at the best price
available at a public or private sale advertised internationally. Such sale may
include an invitation to the BUYER to participate, but will be otherwise on such
terms and conditions as the SELLER may determine.

        In the case of sale of the VESSEL, the SELLER shall give telex or
telefax or written notice to the BUYER.

        (b) In the event of the sale of the VESSEL in its completed state, the
proceeds of sale received by the SELLER shall be applied firstly to payment of
all expenses attending such sale and otherwise incurred by the SELLER as a
result of the BUYER's default, and then to payment of all unpaid installments
and/or unpaid balance of the Contract Price and interest on such installment at
the same interest rate as specified in Section 3 of this Article from the
respective due dates thereof to the date of application.

        (c) In the event of the sale of the VESSEL in its incomplete state, the
proceeds of sale received by the SELLER shall be applied firstly to all expenses
attending such sale and otherwise incurred by the SELLER as a result of the
BUYER's default, and then to payment of all costs of construction of the VESSEL
(such costs of construction, as herein mentioned, shall include but are not
limited to all costs of labor and/or prices paid or to be paid by the SELLER for
the equipment and/or technical design and/or materials purchased or to be
purchased, installed and/or to be installed on the VESSEL) and/or any fees,
charges, expenses and/or royalties incurred and/or to be incurred for the VESSEL
less the installments so retained by the SELLER, and compensation to the SELLER
for a reasonable sum of loss of profit due to the cancellation or rescission of
this Contract.

        (d) In either of the above events of sale, if the proceeds of sale
exceeds the total of the amounts to which such proceeds are to be applied as
aforesaid, the SELLER shall promptly pay the excess to the BUYER, provided,
however that the amount of such payment to the BUYER shall in no event exceed
the total amount of installments already paid by the BUYER and the cost of the
BUYER's supplies, if any, without interest.

                                    INSURANCE

1.      EXTENT OF INSURANCE COVERAGE

        From the time of keel-laying of the first section or block of the VESSEL
until the same is completed, delivered to and accepted by the BUYER, the SELLER
shall, at its own cost and expense, keep the VESSEL and all machinery,
materials, equipment, appurtenances and outfit, delivered to the BUILDER for the
VESSEL or built into, or installed in or upon the VESSEL, including the BUYER's
Supplies, fully insured with first class Chinese insurance companies for
BUILDER's risk.

        The amount of such insurance coverage shall, up to the date of delivery
of the VESSEL, be in an amount at least equal to, but not limited to, the
aggregate of the payments made by the BUYER to the SELLER including the value of
the BUYER's Supplies. The policy referred to hereinabove shall be taken out in
the name of the SELLER and all losses under such policy shall be payable to the
SELLER.

2.      APPLICATION OF RECOVERED AMOUNT

        (a)       Partial Loss:

                  In the event the VESSEL shall be damaged by any insured cause
        whatsoever prior to acceptance and delivery thereof by the BUYER and in
        the further event that such damage shall not constitute an actual or a
        constructive total loss of the VESSEL, the SELLER shall apply the amount
        recovered under the insurance policy referred to in Section 1 of this
        Article to the repair of such damage satisfactory to the Classification
        Society and other institutions or authorities as described in the
        Specifications without additional expenses to the BUYER.

        (b)       Total Loss:

                                                     Shipbuilding Contract H2247

                          (i) By the mutual agreement between the parties
                  hereto, proceed in accordance with terms of this Contract, in
                  which case the amount recovered under said insurance policy
                  shall be applied to the reconstruction and/or repair of the
                  VESSEL's damages and/or reinstallation of BUYER's supplies
                  without additional expenses to the BUYER, provided the parties
                  hereto shall have first agreed in writing as to such
                  reasonable extension of the Delivery Date and adjustment of
                  other terms of this Contract including the Contract Price as
                  may be necessary for the completion of such reconstruction; or

                          (ii) If due to whatever reasons the parties fail to
                  agree on the above, then the BUYER shall deliver a written
                  notice of rejection to SELLER and the SELLER shall refund
                  immediately to the BUYER the amount described in Article II,
                  Section 7, whereupon this Contract shall be deemed to be
                  canceled and all rights, duties, liabilities and obligations
                  of each of the parties to the other shall terminate forthwith.

                          (iii) Notwithstanding the provisions of (i) and (ii)
                  above, Seller may elect to postpone delivery of the Vessel
                  subject to the provisions of Article III, Section (1)(a).

                  Within thirty (30) days after receiving telex or telefax
        notice of any damage to the VESSEL constituting an actual or a
        constructive total loss, the BUYER shall notify the SELLER in writing or
        by telex of its agreement or disagreement under this sub-paragraph. In
        the event the BUYER fails to so notify the SELLER, then such failure
        shall be construed as a disagreement on the part of the BUYER. This
        Contract shall be deemed as rescinded and canceled and the BUYER shall
        receive the refund as hereinabove provided and the provisions hereof
        shall apply.

3.      TERMINATION OF THE SELLER'S OBLIGATION TO INSURE

        The SELLER's obligation to insure the VESSEL hereunder shall cease and
terminate forthwith upon Delivery thereof to and acceptance by the BUYER.

                                  ARTICLE XIII

                                                     Shipbuilding Contract H2247

        Should any dispute of any nature arise in respect of this Contract, its
performance or interpretation which is not decided in accordance with Article
XIII, Section 2 below, such dispute shall be settled by arbitration in London,
England in accordance with the rules of the London Maritime Arbitrators
Association Inc. and otherwise in accordance with the provisions of the Laws of
England. The party who desires arbitration of any such dispute shall give
written notice to the other party. The notice shall state the name and address
of the arbitrator whom it appoints and describe the specific nature of the
particular dispute. Such notice shall be sent by registered air mail and shall
be addressed in the manner set forth in Article XIX, and the other party shall,
within thirty (30) days following the receipt of said notice, give written
notice to the party requesting the arbitration as to the name and address of the
arbitrator whom it appoints, which notice shall be sent by registered air mail
and shall be addressed in the manner set forth in Article XIX, provided that if
the other party should fail to so appoint its arbitrator, the arbitrator
appointed by the party desiring the arbitration may proceed with the arbitration
hearing and issue an award. Otherwise the two arbitrators so chosen shall select
a third arbitrator. The applicable law of England on all matters at issue shall
apply. A judgement based upon the decision of the majority of the arbitrators or
the sole arbitrator, as the case may be, may be entered in the appropriate court
of any country having jurisdiction of either party. The arbitrators shall also
decide which party, or the extent to which each party, shall pay costs of
arbitration. Unless and to the extent otherwise determined by the arbitrator(s),
reference to arbitration shall not relieve the BUILDER of its obligation
diligently to proceed with the construction, completion and delivery of the
VESSEL, but the majority of the arbitrators or the sole arbitrator, as the case
may be, shall decide the extent to which the Delivery Date shall be extended by
virtue of the dispute having been referred to arbitration.

2.      ALTERNATIVE ARBITRATION BY AGREEMENT

        Notwithstanding the preceding provisions of this Article, it is
recognized that in the event of any dispute or difference of opinion arising in
regard to the construction of the VESSEL, her machinery and equipment, or
concerning the quality of materials or workmanship thereof or thereon, such
dispute may be referred to the Classification Society upon mutual agreement of
the parties hereto. In such case, the opinion of the Classification Society
shall be final and binding on the parties hereto.

3.      NOTICE OF AWARD

        Notice of any award shall immediately be given in writing or by telex
confirmed in writing to the SELLER and the BUYER.

                                     [Date]


Navigator Holdings PLC
c/o Cambridge Petroleum Transport Corporation
535 Madison Avenue
19th Floor
New York, New York 10022


Dear Sirs:

At the request of China Shipbuilding Trading Company, Limited ("CSTC") and
Jiangnan Shipyard (the "Builder" and, together with CSTC, the "SELLER") and in
consideration of Navigator Holdings PLC (the "BUYER") agreeing to pay SELLER the
installments of the contract price (the "Contract Price") pursuant to the
Amended and Restated Shipbuilding Contract dated the 26th day of June, 1997, as
amended, supplemented or otherwise modified from time to time (hereinafter
called the "Contract") made by and between the BUYER and the SELLER for the
construction of one (1) 22,000 cubic meter liquefied ethylene gas carrier having
Hull No. 2247 (hereinafter called the "VESSEL"), The Export Import Bank of China
the "Bank") the undersigned, do guarantee the payment (and not merely the
collectability of the same) to the BUYER by the SELLER immediately upon demand
of an amount up to but not exceeding a total amount as set forth in Schedule 1
hereto (calculated in accordance with the immediately following paragraph),
together with simple interest thereon calculated at the rate of ten percent
(10.0%) per annum on the basis of a 360 day year from and including the date of
receipt of demand to but not including the date of remittance by telegraphic
transfer of such refund.

Subject to BUYER making installment payments in accordance with Article II of
the Contract, the amount of this Guarantee will be automatically increased
during the term of this Guarantee and shall be equal to the sum of: (i) the
amount set forth on Schedule 1 hereto calculated as of the first day of the
calendar month in which the

                                                            Amended and Restated
                                                     Shipbuilding Contract H2247

Date of Rejection occurs; and (ii) an amount equal to the product of (X) the
difference between (1) the amount set forth on Schedule 1 hereto calculated as
of the first day of the calendar month immediately succeeding the month in which
the Date of Rejection occurs and (2) the amount set forth on Schedule 1 hereto
as of the first day of the month in which the Date of Rejection of the vessel
under the Contract occurs and (y) a fraction the numerator of which is numeric
day of the month of the date on which the Refund Amount (as hereinafter defined)
is actually paid and the denominator of which is 30 (collectively, the "Refund
Amount").

BUYER's right to demand payment under this Guarantee shall become effective on
the earlier to occur of (i) April 1, 2001, (ii) the date on which the SELLER
fails to pay any liquidated damages payable to BUYER as provided in Section 1(a)
of Article III of the Contract, (iii) upon the cancellation, termination or
rescission of the Contract by the BUYER in accordance with the terms of Contract
as set forth in Article III, 1(a), 2(c), 3(c), 4(c), 5(c), Article X, Article
XII 2(b), or Article XVI (b) or (c), or (iv) the insolvency or bankruptcy of
BUILDER.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to us by the BUYER.

Payment under this Guarantee is available at the counters of ______________ Bank
against presentation of the BUYER's signed statement issued in the form attached
hereto as Appendix A ("Notice of Demand"). If the Notice of Demand is received
by the Bank by 12:00 noon local time on a banking day, the Bank shall pay the
Refund Amount (plus interest thereon) in immediately available funds within ten
(10) banking days. If the Notice of Demand is received by the Bank after 12:00
noon local time on a banking day, the Bank shall pay the Refund Amount (plus
interest thereon) in immediately available funds within eleven (11) banking
days.

This Guarantee is available for one payment only, whether for the full amount
hereof or any part thereof, as may be demanded by the BUYER. In the event that
the BUYER's demand is for a lesser amount than the amount of this Guarantee, the
interest payable will be calculated on the amount of the BUYER's demand and not
on the amount of this Guarantee.

We agree that this Guarantee shall be a continuing guarantee and (i) shall not
be impaired or discharged by the granting of time or any other indulgence to the
SELLER, or any other forbearance (whether as to payment, time, performance, or
otherwise) which might, but for this provision, have any such effect; (ii) shall
not be conditioned or contingent upon the BUYER's pursuit of any remedy that it
has against the SELLER;

<PAGE>


                                                            Amended and Restated
                                                     Shipbuilding Contract H2247

and (iii) shall be unconditional irrespective of any other circumstance that
might otherwise constitute a legal or equitable discharge of a surety or
guarantor under applicable law, and we hereby waive any and all rights (whether
by counterclaim, set off or otherwise) and defenses at law or in equity that may
be available to us by reason of such circumstance.

This Guarantee shall become effective from the time of the actual receipt of the
first installment by the SELLER from the BUYER under the Contract and the Refund
Amount payable under this Guarantee shall correspond to the total installment
payments actually made by the BUYER to the SELLER from time to time under the
Contract prior to the delivery of the VESSEL including applicable interest.

This Guarantee shall expire and become null and void on the earlier to occur of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
the Bank of either a copy of the Protocol of Delivery and Acceptance of the
VESSEL, purportedly signed by the BUYER and the SELLER and issued in the form
attached hereto as Appendix B or a copy of the Certificate of Completion of the
Vessel signed by the respective parties thereto in the form attached hereto as
Appendix C; or (iii) 5:00 p.m. New York time on May 1, 2001, in any such case
this Guarantee shall be returned to us; provided, the Bank further agrees that
its obligations hereunder shall continue to be effective or reinstated, as the
case may be, if at any time any payment, or any part thereof, made by the SELLER
is rescinded or must otherwise be restored by the BUYER upon the bankruptcy or
reorganization of the SELLER.

Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER confirmed by an arbitrator stating that the BUYER's
claim to cancel the Contract or the BUYER's claim for refundment thereunder has
been disputed and referred to arbitration in accordance with the provisions of
the Contract, the period of validity of this Guarantee shall be extended until
thirty (30) days after the final award shall be rendered in the arbitration and
a copy thereof acknowledged by the arbitrators. In such case, this Guarantee
shall not be available unless and until such acknowledged copy of the final
award in the Arbitration justifying the BUYER's claim is presented to us;
subject to any appeal of such final award which may be permitted under English
law; provided the Refund Amount shall be adjusted to reflect the delay resulting
from such arbitration and shall be calculated in accordance with Schedule 1
hereto to the date payment is actually made.

At the request of China Shipbuilding Trading Company, Limited ("CSTC") and

(hereinafter called the "Contracts") made by and between the BUYER and the
SELLER for the construction of five (5) 22,000 cubic meter liquefied ethylene

BUYER by the SELLER, immediately upon demand, of an amount up to but not

Seven Hundred Thousand (US$26,700,000) (the "Payment Amount"), if and when the

This Performance Bond is available for one payment only, whether for the full
amount hereof or any part thereof, as may be demanded by the BUYER.

We agree that this Performance Bond shall be a continuing guarantee and (i)
shall not be impaired or discharged by the granting of time or any other
indulgence to the SELLER, or any other forbearance (whether as to payment, time,

effect; (ii) shall not be conditioned or contingent upon the BUYER's pursuit of
any remedy that it has against the SELLER; and (iii) shall be unconditional
irrespective of any other circumstance that might otherwise constitute a legal
or equitable discharge of a surety or guarantor under applicable law, and we
hereby waive any and all rights (whether by counterclaim, set off or otherwise)
and defenses at law or in equity that may be available to us by reason of such
circumstance.

This Performance Bond shall expire and become null and void on the earlier of

                                                     Shipbuilding Contract H2248

                          (i) the amounts set forth on Schedules 2 and 3 hereto
                  calculated as of the first day of the calendar month in which
                  the Date of Rejection occurs,

                          (ii) an amount equal to the product of (x) the
                  difference between (1) the amount set forth on Schedule 2
                  hereto calculated as of the first day of the calendar month
                  immediately succeeding the month in which the Date of
                  Rejection occurs and (2) the amount set forth on Schedule 2
                  hereto as of the first day of the month in which the Date of
                  Rejection occurs and (y) a fraction the numerator of which is
                  the numeric day of the month of the Date of Rejection and the
                  denominator of which is 30, and

                          (iii) an amount equal to the product of (x) the
                  difference between (1) the amount set forth on Schedule 3

If the amount as calculated above is not paid on the Date of Rejection there
shall be added to such amount interest at the rate of ten percent (10%) per
annum from and including the Date of Rejection to but not including the date
such amount is paid. Such refunds by the SELLER to the BUYER shall forthwith
discharge all obligations, duties, and liabilities of each of the parties hereto
to the other under this Contract. Any and all refunds made to the BUYER under
this Article II, Section 7 shall be made in United States Dollars. Throughout
this Contract, whenever interest is due on any amounts to be paid or refunded by
either party, said interest shall be calculated as simple interest, based on the
actual number of days divided by 360.

        For purposes of this Section 7(a) Date of Rejection means the date on
which written notice of rejection, cancellation or rescission is delivered by
BUYER to SELLER.

                                   ARTICLE III

        The Contract Price of the VESSEL as provided for in Schedule 1 shall be
subject to adjustments as hereinafter set forth. It is hereby understood by both
parties that any reduction of the Contract Price is by way of liquidated damages
and not by way of penalty.

1.      DELIVERY

        (a)       Delayed Delivery Price Adjustment:

                          (i) For purposes of this Contract the Original
                  Delivery Date for the Vessel shall mean the date set forth in
                  Article VII, Section (1) below.

                          (ii) If the Delivery is not made on the Original
                  Delivery Date (subject to a Permissible Delay as defined
                  below), the SELLER shall pay the BUYER, as liquidated damages
                  (not as penalty), the amount of $10,000 for each calendar day
                  for the first ninety (90) calendar days of delay beyond the
                  Extended Delivery Date (as hereinafter defined) and the amount
                  of $13,500 for each calendar day of delay thereafter up to and
                  including the 210th day from the Original Delivery Date
                  ("Original Delay

                  Period"). Liquidated damages calculated with respect to the
                  Original Delay Period shall be recovered by the BUYER through
                  a reduction in the Fifth Installment payable by the BUYER to
                  the SELLER in an amount equal to such Liquidated Damages.

                          (iii) If delivery of the VESSEL is delayed for any
                  reason beyond the Original Delay Period, the Builder may elect
                  to further postpone delivery of the Vessel beyond the Original
                  Delay Period until March 31, 2001 provided SELLER pays
                  liquidated damages monthly in advance to the BUYER at the rate
                  of US$18,000 per day from the end of the Original Delay Period
                  to a date which is 6 months thereafter (the "First Penalty
                  Date"), and US$20,000 per day from the First Penalty Date to
                  the date which is 6 months thereafter (the "Second Penalty
                  Date"), and US$22,000 per day from the Second Penalty Date
                  until March 31, 2001. If the SELLER fails to make any
                  liquidated damages payment, BUYER, in its sole discretion, may
                  either (i) reject the VESSEL or (ii) waive its right to
                  receive the payment of liquidated damages and further reduce
                  the Contract Price for the VESSEL by an amount equal to the
                  liquidated damages which would have been payable.
                  Notwithstanding any other provision contained in this Contract
                  to the contrary, this Contract shall be deemed rescinded on
                  April 1, 2001 and the Buyer shall be entitled to receive the
                  amounts set forth in Article II, Section 7(a) above.

                          Any waiver by the BUYER of its right to receive
                  liquidated damages monthly in advance is not a waiver of the
                  BUYER's right to (a) demand payment of such liquidated damages
                  at a later date, (b) demand monthly advances as to Liquidated
                  Damages for any subsequent months of delay or (c) reject the
                  VESSEL at such later date if liquidated damages are not paid
                  upon demand. The liquidated damages calculated pursuant to
                  this paragraph are in addition to the reduction in the fifth
                  installment of the Contract Price as calculated pursuant to
                  (ii) above for the Original Delay Period.

                          (iv) In the event that the BUYER elects to reject the
                  VESSEL as allowed under this Article III, Section 1(a), the
                  SELLER shall immediately repay to the BUYER the amounts set
                  forth in Article II, Section 7, whereupon this Contract shall
                  terminate and such payment shall forthwith discharge all
                  obligations, duties and liabilities of each party hereto to
                  the other under this Contract.

                  inaction on the part of SELLER; provided such Permissible
                  Delay shall be subject to the following provisions:

                                            (i)     Hull No. 2245 - 60 days
                                            (ii)    Hull No. 2246 - 45 days

                                            (iv)    Hull No. 2248 - 30 days
                                            (v)     Hull No. 2249 - 30 days

                                   (B) For purposes of this Contract the
                          Extended Delivery Date for a Vessel shall mean the
                          Original Delivery Date plus the Permissible Delay for
                          such Vessel,

                                   (C) The aggregated Permissible Delay for the
                          Vessel and the Sister Vessels shall not exceed 150
                          days, and

                                   (D) Subject to the limitations set forth in
                          (A) above, SELLER shall have the right in its sole
                          discretion to designate either the Vessel or any
                          Sister Vessel as to which Vessel will be subject to a
                          Permissible Delay.

        (b)       Early Delivery Price Adjustment:

                          If the SELLER notifies the BUYER by facsimile that the
                  delivery of the VESSEL shall be made earlier than the Original
                  Delivery Date and such notification is given not less than two
                  (2) months prior to the newly planned delivery date, a certain
                  amount of bonus shall be given by the BUYER to the SELLER as

                          In the event that the delivery shall be made earlier
                  than the Original Delivery Date and notice is properly given,
                  then a bonus shall be added to the Contract Price at a rate of

                  for each full day earlier than the Original Delivery Date.

                          The total increase of the Contract Price for the
                  earlier delivery shall be added to the fifth installment of
                  the Contract Price.

death, were caused by negligence of the SELLER, or of any of the SELLER's
employees or agents or subcontractors of the SELLER. Nor shall the SELLER be
under any liability whatsoever to the BUYER for damage to, or loss or
destruction of property in China of the BUYER or of the Supervisor, or of the

                                    ARTICLE V
                        MODIFICATION, CHANGES AND EXTRAS

1.      HOW EFFECTED

        The Specifications in accordance with which the VESSEL is constructed,
may be modified and/or changed at any time hereafter by written agreement of the
parties hereto, provided that such modifications and/or changes or an
accumulation thereof will not, in the BUILDER's reasonable judgment, adversely
affect the BUILDER's other commitments and provided further that the BUYER shall
assent to adjustment of the Contract Price, time of delivery of the VESSEL and
other terms of this Contract, if any, as hereinafter provided. Subject to the
above, the SELLER hereby agree to exert their best efforts to accommodate such
reasonable requests by the BUYER so that the said changes and/or modifications
may be made at a reasonable cost and within the shortest period of time which is
reasonable and possible. Any such agreement for modifications and/or changes
shall include an agreement as to the increase or decrease, if any, in the
Contract Price of the VESSEL together with an agreement as to any extension or
reduction in the time of delivery, providing to the SELLER additional securities
satisfactory to the SELLER, or any other alterations in this Contract, or the
Specifications occasioned by such modifications and/or changes. The
aforementioned agreement to modify and/or to change the Specifications may be
effected by an exchange of duly authenticated letters, telex and telefaxes,
manifesting such agreement. The letters, telexes as well as telefaxes exchanged
by the parties hereto pursuant to the foregoing shall constitute an amendment of
the Specifications under which the VESSEL shall be built, and such letters,
telexes and telefaxes shall be deemed to be incorporated into this Contract and
the Specifications by reference and

made a part hereof. Upon consummation of the agreement to modify and/or to
change the Specifications, the SELLER shall alter the construction of the VESSEL
in accordance therewith, including any additions to, or deductions from, the
work to be performed in connection with such construction. If due to whatever
reasons, the parties hereto shall fail to agree on the adjustment of the
Contract Price or extension of time of delivery or providing additional security
to the SELLER or modification of any terms of this Contract which are
necessitated by such modifications and/or changes, then the SELLER shall have no
obligation to comply with the BUYER's request for any modification and/or
changes.

2.      CHANGES IN RULES AND REGULATIONS

        (a) If, after the Effective Date, any requirements as to the rules and
regulations as specified in this Contract and the Specifications to which the
construction of the VESSEL is required to conform, are altered or changed by the
Classification Society or the other regulatory bodies authorized to make such
alterations or changes, the SELLER and/or the BUYER, upon receipt of the notice
thereof, shall transmit such information in full to each other in writing,
whereupon within twenty one (21) days after receipt of the said notice by the
BUYER from the SELLER or vice versa, the BUYER shall instruct the SELLER in
writing as to the alterations or changes, if any, to be made in the VESSEL which
the BUYER, in its sole discretion, shall decide. The SELLER shall promptly
comply with such alterations or changes, if any in the construction of the
VESSEL, provided that the BUYER shall first agree:

                  (i) As to any increase or decrease in the guaranteed
        deadweight and/or cargo tank capacity and for speed of the VESSEL, if
        such compliance results in increased or reduced deadweight and/or cargo
        tank capacity and speed; and/or

                  (ii) As to any other alterations in the terms of this Contract
        or of Specifications or both, if such compliance makes such alterations
        of the terms necessary.

        Agreement as to such alterations or changes under this Paragraph shall
be made in the same manner as provided above for modifications and/or changes of
the Specifications and/or Plans.

        (b) If, due to whatever reasons, the parties shall fail to agree on the
increase or decrease of the guaranteed speed, deadweight and cargo tank
capacity,

be entitled to proceed with the construction of the VESSEL in accordance with,
and the BUYER shall continue to be bound by, the terms of this Contract and
Specifications without making any such alterations or changes.

        (c) The BUYER and the SELLER hereby agree to make best efforts to avoid
the application and/or minimize the effect of any change in the rules and
regulations of the Classification Society as to the Specifications. If the BUYER
and the SELLER are unsuccessful in avoiding the application of such change in
rules and regulations, then the SELLER shall effect any modifications and/or
changes in Specifications without adjustment to the Contract Price and the BUYER
shall grant to the SELLER the right to extend the Delivery Date (if necessary)
for a maximum period of up to twelve (12) days.

3.      SUBSTITUTION OF MATERIALS AND/OR EQUIPMENT

        In the event that any of the materials and/or equipment required by the
Specifications or otherwise under this Contract for the construction of the
VESSEL cannot be procured in time to effect delivery of the VESSEL, the SELLER
may, provided the SELLER shall provide adequate evidence and the BUYER so agrees
in writing, supply other materials and/or equipment of the equivalent quality,
capable of meeting the requirements of the Classification Society and of the
rules, regulations, requirements and recommendations with which the construction
of the VESSEL must comply.

4.      BUYER'S SUPPLIED ITEMS

        The BUYER shall deliver to the SELLER at its shipyard the items as
specified in the Specifications which the BUYER shall supply for its own account
(the "BUYER's Supplies") by the time designated by the SELLER.

        The delay in the delivery or the failure to deliver by the BUYER of any
BUYER's Supplies within the time specified shall not extend the Delivery Date.

        However, if the delay in delivery of the BUYER's Supplies should exceed
fifteen (15) days, the SELLER shall be entitled to proceed with construction of
the VESSEL without installation of such items in or onto the VESSEL and the
BUYER shall accept the VESSEL so completed.

        The BUILDER shall be responsible for storing and handling of the BUYER's
Supplies as specified in the Specifications after delivery to the BUILDER and
shall install them on board the VESSEL at the BUILDER's expenses.

        Upon arrival of such shipment of the BUYER's Supplies, both parties
shall undertake an joint unpacking inspection. If any damaged BUYER's supplies
are found to be unsuitable for installation, the BUILDER shall be entitled to
refuse to accept the BUYER's Supplies.

                                   ARTICLE VI
                                     TRIALS

1.      NOTICE

        The BUYER and the Supervisor shall receive from the SELLER at least
thirty (30) days notice in advance and seven (7) days definite notice in advance
in writing by telex or telefax, of the time and place of the VESSEL's sea trial
as described in the Specifications (hereinafter referred to as "the Trial Run")
and the BUYER and the Supervisor shall promptly acknowledge receipt of such
notice. The BUYER's representatives and/or the Supervisor shall be on board the
VESSEL to witness such Trial Run, and to check upon the performance of the
VESSEL during the same. Failure of the BUYER's representatives to be present at
the Trial Run of the VESSEL, after due notice to the BUYER and the Supervisor as
provided above, shall have the effect to extend the date for delivery of the
VESSEL by the period of delay caused by such failure to be present. However, if
the Trial Run is delayed more than five (5) days by reason of the failure of the
BUYER's representatives to be present after receipt of due notice as provided
above (other than due to the failure by the BUYER's representative to obtain a
visa to enter China), then in such event, the BUYER shall be deemed to have
waived its right to have its representatives on board the VESSEL during the
Trial Run, and the BUILDER may conduct such Trial Run without the BUYER's
representatives being present, and in such case the BUYER shall be obliged to
accept the VESSEL on the basis of a certificate jointly signed by the BUILDER
and the Classification Society certifying that the VESSEL, after Trial Run
subject to minor alterations and corrections as provided in this Article, if
any, is found to conform to the Contract and Specifications and is satisfactory
in all respects. The SELLER hereby warrants that the necessary visa for the
BUYER's representatives to enter China will be issued in order on demand and
without delay otherwise the Trial Run shall be postponed until the BUYER's
representatives have arrived at the BUILDER's Shipyard. However, should the
nationalities and other personal particulars of the BUYER's representatives be
not acceptable to the SELLER in accordance with its best understanding of the
relevant

rules, regulations and/or Laws of the People's Republic of China then
prevailing, then the SELLER shall so notify the BUYER and the BUYER shall
endeavor to effect the replacement of all or any of such representatives. The
Delivery Date as stipulated in Article VII hereof shall not be extended by any
delays caused by the BUYER's replacement of its representatives pursuant to the
SELLER's request. In the event of unfavorable weather on the date scheduled for
the Trial Run, the same shall take place on the first available day thereafter
that the weather conditions permit. The parties hereto recognize that the
weather conditions in Chinese waters in which the Trial Run is to take place are
such that great changes in weather may arise momentarily and without warning
and, therefore, it is agreed that if during the Trial Run of the VESSEL, the
weather should suddenly become unfavorable, as would have precluded the
continuance of the Trial Run, the Trial Run of the VESSEL shall be discontinued
and postponed until the first favorable day next following, unless the BUYER
assents in writing by telex or telefax of its acceptance of the VESSEL on the
basis of the Trial Run made prior to such sudden change in weather conditions.
In the event that the Trial Run is postponed because of unfavorable weather
conditions, the Delivery Date shall not be extended other than pursuant to
Article VIII hereof.

2.      HOW CONDUCTED

        (a) All expenses in connection with Trial Run of the VESSEL are to be
for the account of the BUILDER, who, during the Trial Run and when subjecting
the VESSEL to Trial Run, is to provide, at its own expense, the necessary crew
to comply with conditions of safe navigation. The Trial Run shall be conducted
in the manner prescribed in the Specifications and shall prove fulfillment of
the performance required for the Trial Run as set forth in the Specifications.

        The course of Trial Run shall be determined by the BUILDER and shall be
conducted within the trial waters equipped with speed measuring facilities.

        (b) The BUILDER shall provide the VESSEL with the required quantities of
water and fuel oil with exception of lubrication oil, hydraulic oil and greases
which shall be supplied by the BUYER according to the BUILDER's schedule which
shall be forwarded to the BUYER by the BUILDER for the conduct of the Trial Run
or Trial Runs as prescribed in the Specifications. The fuel oil supplied by the
SELLER, and lubricating oil, hydraulic oil and greases supplied by the BUYER
shall be in accordance with the applicable engine Specifications, and the cost
of the quantities of water, fuel oil, lubricating oil, hydraulic oil and greases
consumed during the Trial Run or Trial Runs shall be for the account of the
BUILDER.

3.      TRIAL LOAD DRAFT

        In addition to the supplies provided by the BUYER in accordance with
sub-paragraph (b) of the preceding Section 2 of this Article VI, the BUILDER
shall provide the VESSEL with the required quantity of fresh water and other
stores necessary for the conduct of the Trial Run. The necessary ballast (fresh
water, sea water or any other ballast as may be required) to bring the VESSEL to

satisfaction of the BUYER, the Classification Society and any other relevant
authority. After the remedial works are completed the SELLER shall arrange to
re-run the gas trial to the extent which will be necessary to demonstrate that
the rectified part of the Gas Plant is then in conformity with this contract and
the Specifications and the proper functioning of the Gas Plant as a whole is
secured.

        (f) All direct costs and expenses of remedying the non-conformity and
re-running the gas trial (including provision of suitable product, utilities and

an unsuccessful gas trial, remedial works and retrials for which the SELLER is
responsible, with the consequence that the classification certificate has not
been issued, will exceed more than twenty (20) days as from the commencement of
the Gas Trials, the SELLER shall, notwithstanding the provisions contained in
Article IX Section 2 and Section 4, pay to the BUYER as liquidated damages

1.      CAUSE OF DELAY

        If, at any time before actual Delivery, either the construction of the
VESSEL, or any performance required hereunder as a prerequisite of delivery of
the VESSEL, is delayed due to war, blockade, revolution, insurrection,
mobilization, civil commotions, riots, strikes, sabotage, lockouts, local
temperature higher than 35 degree centigrade, Acts of God or the public enemy,
plague or other epidemics, quarantines, prolonged failure or restriction of
electric current from an outside source, freight embargoes, if

any, earthquakes, tidal waves, typhoons, hurricanes, storms or other causes
beyond the control of the BUILDER or of its sub-contractors, as the case may be,
or by force majeure of any description, whether of the nature indicated by the
forgoing or not, or by destruction of the BUILDER or works of the BUILDER or its
sub-contractors, or of the VESSEL or any part thereof, by fire, flood, or other
causes beyond the control of the SELLER or its sub-contractors as the case may
be, then, in the event of delay due to the happening of any of the
aforementioned contingencies, the SELLER shall not be liable for such delay and
the time for delivery of the VESSEL under this Contract shall be extended
without any reduction in the Contract Price subject nevertheless to (i) the
provisions of Section 1(a) of Article III as to reduction in Contract Price,
(ii) the BUYER's right of termination under Section 1(a) of Article III and
(iii) all relevant provisions of this Contract which authorize and permit
extension of the time of delivery of the VESSEL.

2.      NOTICE OF DELAY

        Within fourteen (14) days from the date of commencement of any delay on
account of which the SELLER claims that it is entitled under this Contract to an
extension of the time for delivery of the VESSEL, the SELLER shall advise the
BUYER in writing by telex or telefax of the date such delay commenced, and
reasons therefor.

        Likewise within fourteen (14) days after such delay ends, the SELLER
shall advise the BUYER in writing by telex or telefax of the date such delay
ended, and also shall specify the maximum period of the time by which the date
for delivery of the VESSEL is extended by reason of such delay. Failure of the
BUYER to acknowledge the SELLER's notification of any claim for extension of the
Delivery Date within fourteen (14 ) days after receipt by the BUYER of such
notification, shall be deemed to be a waiver by the BUYER of its right to object
to such extension.

                               WARRANTY OF QUALITY

1.      GUARANTEE OF MATERIAL AND WORKMANSHIP

and equipment thereof that are manufactured or furnished or supplied by the
SELLER and/or its sub-contractors under this Contract including material,
equipment (however excluding any parts for the VESSEL which have been supplied
by or on behalf of the BUYER) against all defects which are due to defective
materials, and/or poor workmanship or failure to construct in conformity with
the Specifications.

2.      NOTICE OF DEFECTS

        The BUYER shall notify the SELLER in writing by telex or telefax, as
promptly as possible, after discovery of any defect or deviations for which a
claim is made under this guarantee. The BUYER's written notice shall describe
the nature of the defect and the extent of the damage caused thereby. The SELLER
shall have no obligation under this guarantee for any defects discovered prior
to the expiry date of the guarantee, unless notice of such defects is received
by the SELLER not later than thirty (30) days after such expiry date. Telexed or
telefaxed advice with brief details explaining the nature of such defect and
extent of damage within thirty (30) days after such expiry date and that a claim
is forthcoming will be sufficient to comply with the requirements as to time.

3.      REMEDY OF DEFECTS

        The SELLER shall remedy at its expense any defect, against which the
VESSEL or any part of the equipment thereof is guaranteed under this Article by
making all necessary repairs and/or replacement. Such repairs and/or replacement
will be made by the SELLER.

        However, if it is impractical to make the repair by the SELLER, and if
forwarding by the SELLER of replacement part, and materials cannot be
accomplished without impairing or delaying the operation of the VESSEL, then, in
any such event, the BUYER shall cause the necessary repairs or replacements to
be made elsewhere at the discretion of the BUYER provided that the BUYER shall,
as soon as possible, give the SELLER notice in writing by telex or telefax of
the time and place such repairs will be made, provided always that the burden of
proof as to the necessity for such repairs and replacements shall rest with the
BUYER, and a written confirmation for such repairs or replacement shall be
obtained from the SELLER. Defects that affect the safety of the VESSEL or her
crew and/or constitute an emergency shall be repaired either by the crew or a
BUYER selected contractor in a manner reasonable under the circumstances without
the SELLER's prior approval and the SELLER shall be notified as to the nature
and extent of repairs as soon as possible after the repairs are undertaken and
such repair work will be subject to the mutual agreement between the parties. If
the VESSEL is not thereby delayed or her operation is not thereby delayed or
impaired, the SELLER shall have the right to verify the nature and extent of the
defects complained of by its own representative(s) or that of Classification
Society. The SELLER shall, in such cases, promptly advise the BUYER, by telex or
telefax, after such examination has been completed, of its acceptance or
rejection of the defects as ones justifying the

remedy under this Article. In all minor cases, the Guarantee Engineer, as
hereinafter provided for, will act for and on behalf of the SELLER.

        In any circumstances, the SELLER shall immediately pay to the BUYER in
United States Dollars by telegraphic transfer the actual cost for such repairs
or replacements including forwarding charges, or at the average cost for making
similar repairs or replacements including forwarding charges as quoted by a
leading shipyard each in China, Singapore, Korea and Spain, whichever is lower:

        remedy under this Article, or

                  (b) If the SELLER neither accepts nor rejects the defects as
        above provided, nor requests arbitration within thirty (30) days after
        its receipt of the BUYER's notice of defects.

        Any dispute shall be referred to arbitration in accordance with the
provisions of Article XIII hereof.

4.      EXTENT OF THE SELLER'S LIABILITY

        The SELLER shall have no obligation and/or liabilities with respect to
defects discovered after the expiration of the period of guarantee specified
above.

        The SELLER shall be liable to the BUYER for defects and damages caused
by any of the defects specified in Section 1 of this Article provided that such
liability of the SELLER shall be limited to damage occasioned within the
guarantee period specified in Paragraph 1 above. The SELLER shall not be
obligated to repair, or to be liable for, damages to the VESSEL, or to any part
of the equipment thereof, due to ordinary wear and tear or caused by defects
other than those specified in Paragraph 1 above, nor shall there be any SELLER's
liability hereunder for defects in the VESSEL, or any part of the equipment
thereof, caused by fire or accidents at sea or elsewhere, or mismanagement,
accidents, negligence, or willful neglect, on the part of the BUYER, its
employees or agents including the VESSEL's officers, crew and passengers, or any
persons on or doing work on the VESSEL other than the SELLER, its employees,
agents or sub-contractors. Likewise, the SELLER shall not be liable for defects
in the VESSEL, or the equipment or any part thereof, due to repairs or
replacement which were made by those other than the SELLER and/or their
sub-contractors, employees or agents.

special loss, or expenses arising from any cause whatsoever including, without
limitation, loss of time, loss of profit or earnings or demurrage directly from

or implied, arising by Law or otherwise (including without limitation any

consequential damages) or whether or not occasioned by the SELLER's negligence.
This guarantee shall not be extended, altered or varied except by a written
instrument signed by the duly authorized representatives of the SELLER, and the
BUYER.

        The BUILDER shall appoint one guarantee engineer (the "Guarantee
Engineer") to serve the VESSEL as the BUILDER's representative for a period of
six (6) months from the delivery of the VESSEL. The BUYER and its employees

cost to the BUILDER and/or the Guarantee Engineer.

        The BUYER shall pay to the Guarantee Engineer the sum of United States

5.      SALE OF THE VESSEL

        (a) In the event of cancellation or rescission of this Contract as above
provided, the SELLER shall have full right and power either to complete or not

proceeds of sale received by the SELLER shall be applied firstly to all expenses
attending such sale and otherwise incurred by the SELLER as a result of the
BUYER's default, and then to payment of all costs of construction of the VESSEL
(such costs of construction, as herein mentioned, shall include but are not
limited to all costs of labor and/or prices paid or to be paid by the SELLER for
the equipment and/or technical design and/or materials purchased or to be

aforesaid, the SELLER shall promptly pay the excess to the BUYER, provided,
however that the amount of such payment to the BUYER shall in no event exceed
the total amount of installments already paid by the BUYER and the cost of the
BUYER's supplies, if any, without interest.

materials, equipment, appurtenances and outfit, delivered to the BUILDER for the
VESSEL or built into, or installed in or upon the VESSEL, including the BUYER's
Supplies, fully insured with first class Chinese insurance companies for

2.      APPLICATION OF RECOVERED AMOUNT

        (a)       Partial Loss:

                  In the event the VESSEL shall be damaged by any insured cause
        whatsoever prior to acceptance and delivery thereof by the BUYER and in
        the further event that such damage shall not constitute an actual or a
        constructive total loss of the VESSEL, the SELLER shall apply the amount
        recovered under the insurance policy referred to in Section 1 of this
        Article to the repair of such damage satisfactory to the Classification
        Society and other institutions or authorities as described in the
        Specifications without additional expenses to the BUYER.

        (b)       Total Loss:

                          (i) By the mutual agreement between the parties
                  hereto, proceed in accordance with terms of this Contract, in
                  which case the amount recovered under said insurance policy
                  shall be applied to the reconstruction and/or repair of the
                  VESSEL's damages and/or reinstallation of BUYER's supplies
                  without additional expenses to the BUYER, provided the parties
                  hereto shall have first agreed in writing as to such
                  reasonable extension of the Delivery Date and adjustment of
                  other terms of this Contract including the Contract Price as
                  may be necessary for the completion of such reconstruction; or

                          (ii) If due to whatever reasons the parties fail to
                  agree on the above, then the BUYER shall deliver a written
                  notice of rejection to SELLER and the SELLER shall refund
                  immediately to the BUYER the amount described in Article II,
                  Section 7, whereupon this Contract shall be deemed to be

                  of each of the parties to the other shall terminate forthwith.

                          (iii) Notwithstanding the provisions of (i) and (ii)
                  above, Seller may elect to postpone delivery of the Vessel
                  subject to the provisions of Article III, Section (1)(a).

                  Within thirty (30) days after receiving telex or telefax
        notice of any damage to the VESSEL constituting an actual or a
        constructive total loss, the BUYER shall notify the SELLER in writing or
        by telex of its agreement or disagreement under this sub-paragraph. In
        the event the BUYER fails to so notify the SELLER, then such failure
        shall be construed as a disagreement on the part of the BUYER. This
        Contract shall be deemed as rescinded and canceled and the BUYER shall
        receive the refund as hereinabove provided and the provisions hereof
        shall apply.

3.      TERMINATION OF THE SELLER'S OBLIGATION TO INSURE

        Should any dispute of any nature arise in respect of this Contract, its
performance or interpretation which is not decided in accordance with Article
XIII, Section 2 below, such dispute shall be settled by arbitration in London,
England in accordance with the rules of the London Maritime Arbitrators
Association Inc. and otherwise in accordance with the provisions of the Laws of
England. The party who desires arbitration of any such dispute shall give
written notice to the other party. The notice shall state the name and address
of the arbitrator whom it appoints and describe the specific nature of the
particular dispute. Such notice shall be sent by registered air mail and shall
be addressed in the manner set forth in Article XIX, and the other party shall,
within thirty (30) days following the receipt of said notice, give written
notice to the party requesting the arbitration as to the name and address of the
arbitrator whom it appoints, which notice shall be sent by registered air mail
and shall be addressed in the manner set forth in Article XIX, provided that if
the other party should fail to so appoint its arbitrator, the arbitrator
appointed by the party desiring the arbitration may proceed with the arbitration
hearing and issue an award. Otherwise the two arbitrators so chosen shall select
a third arbitrator. The applicable law of England on all matters at issue shall
apply. A judgement based upon the decision of the majority of the arbitrators or
the sole arbitrator, as the case may be, may be entered in the appropriate court
of any country having jurisdiction of either party. The arbitrators shall also
decide which party, or the extent to which each party, shall pay costs of
arbitration. Unless and to the extent otherwise determined by the arbitrator(s),
reference to arbitration shall not relieve the BUILDER of its obligation
diligently to proceed with the construction, completion and delivery of the
VESSEL, but the majority of the arbitrators or the sole arbitrator, as the case
may be, shall decide the extent to which the Delivery Date shall be extended by
virtue of the dispute having been referred to arbitration.

2.      ALTERNATIVE ARBITRATION BY AGREEMENT

        Notwithstanding the preceding provisions of this Article, it is
recognized that in the event of any dispute or difference of opinion arising in
regard to the construction of the VESSEL, her machinery and equipment, or
concerning the quality of materials or workmanship thereof or thereon, such
dispute may be referred to the Classification Society upon mutual agreement of
the parties hereto. In such case, the opinion of the Classification Society
shall be final and binding on the parties hereto.

3.      NOTICE OF AWARD

        Notice of any award shall immediately be given in writing or by telex
confirmed in writing to the SELLER and the BUYER.

Navigator Holdings PLC
c/o Cambridge Petroleum Transport Corporation
535 Madison Avenue
19th Floor
New York, New York 10022


Dear Sirs:

At the request of China Shipbuilding Trading Company, Limited ("CSTC") and
Jiangnan Shipyard (the "Builder" and, together with CSTC, the "SELLER") and in
consideration of Navigator Holdings PLC (the "BUYER") agreeing to pay SELLER the
installments of the contract price (the "Contract Price") pursuant to the
Amended and Restated Shipbuilding Contract dated the 26th day of June, 1997, as
amended, supplemented or otherwise modified from time to time (hereinafter
called the "Contract") made by and between the BUYER and the SELLER for the
construction of one (1) 22,000 cubic meter liquefied ethylene gas carrier having
Hull No. 2248 (hereinafter called the "VESSEL"), The Export Import Bank of China
the "Bank") the undersigned, do guarantee the payment (and not merely the
collectability of the same) to the BUYER by the SELLER immediately upon demand
of an amount up to but not exceeding a total amount as set forth in Schedule 1
hereto (calculated in accordance with the immediately following paragraph),
together with simple interest thereon calculated at the rate of ten percent
(10.0%) per annum on the basis of a 360 day year from and including the date of
receipt of demand to but not including the date of remittance by telegraphic
transfer of such refund.

Subject to BUYER making installment payments in accordance with Article II of
the Contract, the amount of this Guarantee will be automatically increased
during the term of this Guarantee and shall be equal to the sum of: (i) the
amount set forth on Schedule 1 hereto calculated as of the first day of the
calendar month in which the Date

                                                       Amended and Restated
                                                     Shipbuilding Contract H2248

of Rejection occurs; and (ii) an amount equal to the product of (X) the
difference between (1) the amount set forth on Schedule 1 hereto calculated as
of the first day of the calendar month immediately succeeding the month in which
the Date of Rejection occurs and (2) the amount set forth on Schedule 1 hereto
as of the first day of the month in which the Date of Rejection of the vessel
under the Contract occurs and (y) a fraction the numerator of which is numeric
day of the month of the date on which the Refund Amount (as hereinafter defined)
is actually paid and the denominator of which is 30 (collectively, the "Refund
Amount").

BUYER's right to demand payment under this Guarantee shall become effective on
the earlier to occur of (i) April 1, 2001, (ii) the date on which the SELLER
fails to pay any liquidated damages payable to BUYER as provided in Section 1(a)
of Article III of the Contract, (iii) upon the cancellation, termination or
rescission of the Contract by the BUYER in accordance with the terms of Contract
as set forth in Article III, 1(a), 2(c), 3(c), 4(c), 5(c), Article X, Article
XII 2(b), or Article XVI (b) or (c), or (iv) the insolvency or bankruptcy of
BUILDER.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to us by the BUYER.

Payment under this Guarantee is available at the counters of ______________ Bank
against presentation of the BUYER's signed statement issued in the form attached
hereto as Appendix A ("Notice of Demand"). If the Notice of Demand is received
by the Bank by 12:00 noon local time on a banking day, the Bank shall pay the
Refund Amount (plus interest thereon) in immediately available funds within ten
(10) banking days. If the Notice of Demand is received by the Bank after 12:00
noon local time on a banking day, the Bank shall pay the Refund Amount (plus
interest thereon) in immediately available funds within eleven (11) banking
days.

This Guarantee is available for one payment only, whether for the full amount
hereof or any part thereof, as may be demanded by the BUYER. In the event that
the BUYER's demand is for a lesser amount than the amount of this Guarantee, the
interest payable will be calculated on the amount of the BUYER's demand and not
on the amount of this Guarantee.

We agree that this Guarantee shall be a continuing guarantee and (i) shall not
be impaired or discharged by the granting of time or any other indulgence to the
SELLER, or any other forbearance (whether as to payment, time, performance, or
otherwise) which might, but for this provision, have any such effect; (ii) shall
not be conditioned or contingent upon the BUYER's pursuit of any remedy that it
has against the SELLER;


                                       A-2
<PAGE>

                                                       Amended and Restated
                                                     Shipbuilding Contract H2248

and (iii) shall be unconditional irrespective of any other circumstance that
might otherwise constitute a legal or equitable discharge of a surety or
guarantor under applicable law, and we hereby waive any and all rights (whether
by counterclaim, set off or otherwise) and defenses at law or in equity that may
be available to us by reason of such circumstance.

This Guarantee shall become effective from the time of the actual receipt of the
first installment by the SELLER from the BUYER under the Contract and the Refund
Amount payable under this Guarantee shall correspond to the total installment
payments actually made by the BUYER to the SELLER from time to time under the
Contract prior to the delivery of the VESSEL including applicable interest.

This Guarantee shall expire and become null and void on the earlier to occur of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
the Bank of either a copy of the Protocol of Delivery and Acceptance of the
VESSEL, purportedly signed by the BUYER and the SELLER and issued in the form
attached hereto as Appendix B or a copy of the Certificate of Completion of the
Vessel signed by the respective parties thereto in the form attached hereto as
Appendix C; or (iii) 5:00 p.m. New York time on May 1, 2001, in any such case
this Guarantee shall be returned to us; provided, the Bank further agrees that
its obligations hereunder shall continue to be effective or reinstated, as the
case may be, if at any time any payment, or any part thereof, made by the SELLER
is rescinded or must otherwise be restored by the BUYER upon the bankruptcy or
reorganization of the SELLER.

Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER confirmed by an arbitrator stating that the BUYER's
claim to cancel the Contract or the BUYER's claim for refundment thereunder has
been disputed and referred to arbitration in accordance with the provisions of
the Contract, the period of validity of this Guarantee shall be extended until
thirty (30) days after the final award shall be rendered in the arbitration and
a copy thereof acknowledged by the arbitrators. In such case, this Guarantee
shall not be available unless and until such acknowledged copy of the final
award in the Arbitration justifying the BUYER's claim is presented to us;
subject to any appeal of such final award which may be permitted under English
law; provided the Refund Amount shall be adjusted to reflect the delay resulting
from such arbitration and shall be calculated in accordance with Schedule 1
hereto to the date payment is actually made.

Dear Sirs:

At the request of China Shipbuilding Trading Company, Limited ("CSTC") and
Jiangnan Shipyard (the "Builder" and together with CSTC collectively called the
"SELLER") and in consideration of Navigator Holdings, PLC (the "BUYER") agreeing
to pay SELLER the installments of the contract price (the "Contract Price")
pursuant to the Amended and Restated Shipbuilding Contracts dated the 26th day
of June, 1997, as amended, supplemented or otherwise modified from time to time
(hereinafter called the "Contracts") made by and between the BUYER and the
SELLER for the construction of five (5) 22,000 cubic meter liquefied ethylene
gas carriers respectively having Hull Nos. 2245, 2246, 2247, 2248 and 2249
(hereinafter called the "VESSELS"), Export-Import Bank of China (the "Bank")
guarantees the payment (and not merely the collectability of the same) to the
BUYER by the SELLER, immediately upon demand, of an amount up to but not
exceeding a total aggregate amount of United States Dollars Twenty Six Million
Seven Hundred Thousand (US$26,700,000) (the "Payment Amount"), if and when the
same or any part thereof becomes payable to BUYER from the SELLER under any
Contract or Contracts if any such Contract or Contracts are cancelled by the
BUYER in accordance with the terms (Article III, 1(a), 2(c), 3(c), 4(c), 5(c),
Article X, Article XII 2(b) and Article XVI (b) and (c)) of such Contract or
Contracts (any a "Cancellation Event"). This Performance Bond shall become
effective upon actual receipt in full by the SELLER of the initial installment
due under each of the Contracts.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to the BANK by the BUYER.


                                       B-1

                                                       Amended and Restated
                                                     Shipbuilding Contract H2248

Payment under this Performance Bond is available at the counters of
Export-Import Bank of China in __________________ against presentation of the
BUYER's signed statement issued in the form attached hereto as Appendix A
("Notice of Demand"). The Notice of Demand shall set forth the dollar amount to
be paid to the BUYER under this Performance Bond, which amount shall be based
upon Schedule 1 attached hereto (the "Demand Amount") provided such Demand
Amount shall not exceed the Payment Amount. As to any date on which a Notice of
Demand is presented, the Demand Amount shall be equal to the amount set forth
opposite the calendar month in which such Notice of Demand is presented under
the column heading specified in the Notice of Demand. If the Notice of Demand is
received by the Bank by 12:00 noon local time on a banking day, the Bank shall
pay the Demand Amount in immediately available funds within ten (10) banking
days. If the Notice of Demand is received by the Bank after 12:00 noon local
time on a banking day, the Bank shall pay the Demand Amount in immediately
available funds within eleven (11) banking days.

The right of the BUYER to demand payment under this Performance Bond by
presentation of a Notice of Demand shall become effective on the earlier to
occur of (i) April 1, 2001, (ii) the date on which the SELLER fails to pay any
liquidated damages payable to BUYER as provided in Section 1(a) of Article III
of the Contracts, (iii) the occurrence of a Cancellation Event or (iv) the
bankruptcy or insolvency of the Builder.

This Performance Bond is available for one payment only, whether for the full
amount hereof or any part thereof, as may be demanded by the BUYER.

We agree that this Performance Bond shall be a continuing guarantee and (i)
shall not be impaired or discharged by the granting of time or any other
indulgence to the SELLER, or any other forbearance (whether as to payment, time,
performance, or otherwise) which might, but for this provision, have any such
effect; (ii) shall not be conditioned or contingent upon the BUYER's pursuit of
any remedy that it has against the SELLER; and (iii) shall be unconditional
irrespective of any other circumstance that might otherwise constitute a legal
or equitable discharge of a surety or guarantor under applicable law, and we
hereby waive any and all rights (whether by counterclaim, set off or otherwise)
and defenses at law or in equity that may be available to us by reason of such
circumstance.

This Performance Bond shall expire and become null and void on the earlier of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
Bank of a copy of the Protocol of Acceptance and Delivery or Certificates of
Completion for each of the five (5) VESSELS in the form of Appendix B or
Appendix C to this Performance Bond; or (iii) 5:00 p.m. New York time on May 1,
2001, in any such case this Performance Bond shall be returned to us; provided,
the Bank further agrees that its obligations hereunder shall continue to be
effective or reinstated, as the case may be, if at any time any payment, or any
part thereof, made by the SELLER is rescinded or must otherwise be restored by
the BUYER upon the bankruptcy or reorganization of the SELLER.

Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER stating that the BUYER's claim to cancel the Contracts
or the BUYER's claim for payment thereunder has been disputed and referred to
arbitration in accordance with the provisions of the Contracts, the period of
validity of this Performance Bond shall be extended until thirty (30) days after
the final award shall be rendered in the arbitration and a copy thereof
acknowledged by the arbitrators. In such case, this Performance Bond shall not
be available unless and until such acknowledged copy of the final award in the
Arbitration justifying the BUYER's claim is presented to us; subject to any
appeal of such final award which may be permitted under English law.

Dear Sirs:

At the request of Tractebel Gas Engineering GmBH and in consideration of
Navigator Holdings, PLC (the "BUYER") agreeing to pay China Shipbuilding Trading
Company, Limited ("CSTC") and Jiangnan Shipyard (the "Builder" together with
CSTC collectively called the "SELLER") the installments of the contract price
(the "Contract Price") pursuant to the Amended and Restated Shipbuilding
Contracts dated the 26th day of June, 1997, as amended, supplemented or
otherwise modified from time to time (hereinafter called the "Contracts") made
by and between the BUYER and the SELLER for the construction of five (5) 22,000
cubic meter liquefied ethylene gas carriers having Hull Nos. 2245, 2246, 2247,
2248 and 2249 (hereinafter called the "VESSELS"), Generale de Banque (the
"Bank") guarantees the payment (and not merely the collectability of the same)
to the BUYER by the SELLER, immediately upon demand, of an amount up to but not
exceeding a total aggregate amount of United States Dollars Thirteen Million
Three Hundred Thousand (US$13,300,000) (the "Payment Amount"), if and when the
same or any part thereof become payable to BUYER from the SELLER under any
Contract or Contracts if any such contract or contracts are cancelled by the
BUYER in accordance with the terms (Article III, 1(a), 2(c), 3(c), 4(c), 5(c),
Article X, Article XII 2(b) and Article XVI(b) and (c)) of the Contracts (any a
"Cancellation Event"). This Performance Bond shall become effective upon payment
of the initial installment under each of the Contracts.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to the BANK by the BUYER.

Payment under this Performance Bond is available at the counters of
_______________ against presentation of the BUYER's signed statement issued in
the form attached hereto as Appendix A ("Notice of Demand"). The Notice of
Demand shall set forth the dollar amount to be paid to the


                                       C-1
<PAGE>

BUYER under this Performance Bond, which amount shall be based upon Schedule 1
attached hereto (the "Demand Amount") provided such Demand Amount shall not
exceed the Payment Amount. As to any date on which a Notice of Demand is
presented, the Demand Amount shall be equal to the amount set forth opposite the
calendar month in which such Notice of Demand is presented and under the column
heading specified in the Notice of Demand less the amount paid by the
Export-Import Bank of China under such Bank's Irrevocable Performance Bond dated
_______, 1997 (the "Ex-Im Performance Bond"). In addition, the BUYER's right to
demand payment as provided above is subject to delivery by BUYER to the Bank of
a copy of the notice of demand presented to the Export-Import Bank of China
under the Ex-Im Performance Bond in the amount of US$26,700,000 and evidence
that such amount has been paid.

If the Notice of Demand is received by the Bank by 12:00 noon local time on a
business day, the Bank shall pay the Demand Amount in immediately available
funds on the same business day. If the Notice of Demand is received by the Bank
after 12:00 noon local time on a business day, the Bank shall pay the Demand
Amount in immediately available funds on the next succeeding business day.

The right of the BUYER to demand payment under this Performance Bond shall
become effective on the earlier to occur of (i) April 1, 2001, (ii) the date on
which the SELLER fails to pay any liquidated damages payable to BUYER as
provided in Section 1(a) of Article III of the Contracts, (iii) the occurrence
of a Cancellation Event or (iv) the bankruptcy or insolvency of the Builder.

This Performance Bond is available for one payment only, whether for the full
amount hereof or any part thereof, as may be demanded by the BUYER.

We agree that this Performance Bond shall be a continuing guarantee and (i)
shall not be impaired or discharged by the granting of time or any other
indulgence to the SELLER, or any other forbearance (whether as to payment, time,
performance, or otherwise) which might, but for this provision, have any such
effect; (ii) shall not be conditioned or contingent upon the BUYER's pursuit of
any remedy that it has against the SELLER; and (iii) shall be unconditional
irrespective of any other circumstance that might otherwise constitute a legal
or equitable discharge of a surety or guarantor under applicable law, and we
hereby waive any and all rights (whether by counterclaim, set off or otherwise)
and defenses at law or in equity that may be available to us by reason of such
circumstance.

This Performance Bond shall expire and become null and void on the earlier of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
Bank of a copy of the Protocol of Acceptance and Delivery and/or Certificates of
Completion for each of the five (5) VESSELs in the form of Appendix B or
Appendix C to this Performance Bond; and (iii) 5:00 p.m. New York time on May 1,
2001, in any such case this Performance Bond shall be returned to us; provided,
the Bank further agrees that its obligations hereunder shall continue to be
effective or reinstated, as the case may be, if at any time any payment, or any
part thereof, made by the SELLER is rescinded or must otherwise be restored by
the BUYER upon the bankruptcy or reorganization of the SELLER.


                                       C-2
<PAGE>

Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER confirmed by an arbitrator stating that the BUYER's
claim to cancel the Contracts or the BUYER's claim for refundment thereunder has
been disputed and referred to arbitration in accordance with the provisions of
the Contract, the period of validity of this Performance Bond shall be extended
until thirty (30) days after the final award shall be rendered in the
arbitration and a copy thereof acknowledged by the arbitrators. In such case,
this Performance Bond shall not be available unless and until such acknowledged
copy of the final award in the Arbitration justifying the BUYER's claim is
presented to us; subject to any appeal of such final award which may be
permitted under English law.

This Performance Bond is governed by and enforced and construed in accordance
with the laws of England.

                          (ii) an amount equal to the product of (x) the
                  difference between (1) the amount set forth on Schedule 2
                  hereto calculated as of the first day of the calendar month

                  the numeric day of the month of the Date of Rejection and the
                  denominator of which is 30, and

                          (iii) an amount equal to the product of (x) the

                  the numeric day of the month of the Date of Rejection and the
                  denominator of which is 30.

If the amount as calculated above is not paid on the Date of Rejection there

        The Contract Price of the VESSEL as provided for in Schedule 1 shall be
subject to adjustments as hereinafter set forth. It is hereby understood by both

1.      DELIVERY

        (a)       Delayed Delivery Price Adjustment:

                          (i) For purposes of this Contract the Original
                  Delivery Date for the Vessel shall mean the date set forth in
                  Article VII, Section (1) below.

                          (ii) If the Delivery is not made on the Original
                  Delivery Date (subject to a Permissible Delay as defined
                  below), the SELLER shall pay the BUYER, as liquidated damages
                  (not as penalty), the amount of $10,000 for each calendar day

                  Extended Delivery Date (as hereinafter defined) and the amount
                  of $13,500 for each calendar day of delay thereafter up to and

                  BUYER through a reduction in the Fifth Installment payable by
                  the BUYER to the SELLER in an amount equal to such Liquidated
                  Damages.

                                                     Shipbuilding Contract H2249

                          (iii) If delivery of the VESSEL is delayed for any
                  reason beyond the Original Delay Period, the Builder may elect
                  to further postpone delivery of the Vessel beyond the Original
                  Delay Period until March 31, 2001 provided SELLER pays
                  liquidated damages monthly in advance to the BUYER at the rate
                  of US$18,000 per day from the end of the Original Delay Period
                  to a date which is 6 months thereafter (the "First Penalty
                  Date"), and US$20,000 per day from the First Penalty Date to
                  the date which is 6 months thereafter (the "Second Penalty
                  Date"), and US$22,000 per day from the Second Penalty Date
                  until March 31, 2001. If the SELLER fails to make any
                  liquidated damages payment, BUYER, in its sole discretion, may
                  either (i) reject the VESSEL or (ii) waive its right to
                  receive the payment of liquidated damages and further reduce
                  the Contract Price for the VESSEL by an amount equal to the
                  liquidated damages which would have been payable.
                  Notwithstanding any other provision contained in this Contract
                  to the contrary, this Contract shall be deemed rescinded on
                  April 1, 2001 and the Buyer shall be entitled to receive the
                  amounts set forth in Article II, Section 7(a) above.

                          Any waiver by the BUYER of its right to receive
                  liquidated damages monthly in advance is not a waiver of the
                  BUYER's right to (a) demand payment of such liquidated damages
                  at a later date, (b) demand monthly advances as to Liquidated
                  Damages for any subsequent months of delay or (c) reject the
                  VESSEL at such later date if liquidated damages are not paid
                  upon demand. The liquidated damages calculated pursuant to
                  this paragraph are in addition to the reduction in the fifth
                  installment of the Contract Price as calculated pursuant to
                  (ii) above for the Original Delay Period.

                          (iv) In the event that the BUYER elects to reject the
                  VESSEL as allowed under this Article III, Section 1(a), the
                  SELLER shall immediately repay to the BUYER the amounts set
                  forth in Article II, Section 7, whereupon this Contract shall
                  terminate and such payment shall forthwith discharge all
                  obligations, duties and liabilities of each party hereto to
                  the other under this Contract.

                          (v) For the purpose of this Article, the delivery of
                  the VESSEL shall not be deemed delayed and the Contract Price
                  shall not be reduced when and if the Original Delivery Date of
                  the VESSEL is extended by reason of a Permissible Delay. For
                  purposes of this Article a Permissible Delay means a delay
                  caused by reason of causes and provisions of (1) Section 2 of

                        MODIFICATION, CHANGES AND EXTRAS

1.      HOW EFFECTED

        The Specifications in accordance with which the VESSEL is constructed,
may be modified and/or changed at any time hereafter by written agreement of the
parties hereto, provided that such modifications and/or changes or an
accumulation thereof will not, in the BUILDER's reasonable judgment, adversely
affect the BUILDER's other commitments and provided further that the BUYER shall
assent to adjustment of the Contract Price, time of delivery of the VESSEL and
other terms of this Contract, if any, as hereinafter provided. Subject to the
above, the SELLER hereby agree to exert their best efforts to accommodate such
reasonable requests by the BUYER so that the said changes and/or modifications
may be made at a reasonable cost and within the shortest period of time which is
reasonable and possible. Any such agreement for modifications and/or changes
shall include an agreement as to the increase or decrease, if any, in the
Contract Price of the VESSEL together with an agreement as to any extension or
reduction in the time of delivery, providing to the SELLER additional securities
satisfactory to the SELLER, or any other alterations in this Contract, or the
Specifications occasioned by such modifications and/or changes. The
aforementioned agreement to modify and/or to change the Specifications may be
effected by an exchange of duly authenticated letters, telex and telefaxes,
manifesting such agreement. The letters, telexes as well as telefaxes exchanged
by the parties hereto pursuant to the foregoing shall constitute an amendment of
the Specifications under which the VESSEL shall be built, and such letters,
telexes and telefaxes shall be deemed to be incorporated into this Contract and
the Specifications by reference and made a part hereof. Upon consummation of the

in accordance therewith, including any additions to, or deductions from, the
work to be performed in connection with such construction. If due to whatever
reasons, the parties hereto shall fail to agree on the adjustment of the
Contract Price or extension of time of delivery or providing additional security
to the SELLER or modification of any terms of this Contract which are
necessitated by such modifications and/or changes, then the SELLER shall have no
obligation to comply with the BUYER's request for any modification and/or
changes.

2.      CHANGES IN RULES AND REGULATIONS

        (a) If, after the Effective Date, any requirements as to the rules and
regulations as specified in this Contract and the Specifications to which the

Classification Society or the other regulatory bodies authorized to make such
alterations or changes, the SELLER and/or the BUYER, upon receipt of the notice
thereof, shall transmit such information in full to each other in writing,
whereupon within twenty one (21) days after receipt of the said notice by the
BUYER from the SELLER or vice versa, the BUYER shall instruct the SELLER in
writing as to the alterations or changes, if any, to be made in the VESSEL which
the BUYER, in its sole discretion, shall decide. The SELLER shall promptly
comply with such alterations or changes, if any in the construction of the
VESSEL, provided that the BUYER shall first agree:

                  (i) As to any increase or decrease in the guaranteed
        deadweight and/or cargo tank capacity and for speed of the VESSEL, if
        such compliance results in increased or reduced deadweight and/or cargo
        tank capacity and speed; and/or

                  (ii) As to any other alterations in the terms of this Contract
        or of Specifications or both, if such compliance makes such alterations
        of the terms necessary.

        Agreement as to such alterations or changes under this Paragraph shall
be made in the same manner as provided above for modifications and/or changes of
the Specifications and/or Plans.

        (b) If, due to whatever reasons, the parties shall fail to agree on the
increase or decrease of the guaranteed speed, deadweight and cargo tank
capacity, or any alteration of the terms of this Contract, if any, then the
SELLER shall be entitled to proceed with the construction of the VESSEL in
accordance

and Specifications without making any such alterations or changes.

        (c) The BUYER and the SELLER hereby agree to make best efforts to avoid
the application and/or minimize the effect of any change in the rules and
regulations of the Classification Society as to the Specifications. If the BUYER
and the SELLER are unsuccessful in avoiding the application of such change in
rules and regulations, then the SELLER shall effect any modifications and/or
changes in Specifications without adjustment to the Contract Price and the BUYER
shall grant to the SELLER the right to extend the Delivery Date (if necessary)
for a maximum period of up to twelve (12) days.

3.      SUBSTITUTION OF MATERIALS AND/OR EQUIPMENT

        In the event that any of the materials and/or equipment required by the
Specifications or otherwise under this Contract for the construction of the
VESSEL cannot be procured in time to effect delivery of the VESSEL, the SELLER
may, provided the SELLER shall provide adequate evidence and the BUYER so agrees
in writing, supply other materials and/or equipment of the equivalent quality,
capable of meeting the requirements of the Classification Society and of the
rules, regulations, requirements and recommendations with which the construction
of the VESSEL must comply.

        The BUYER shall deliver to the SELLER at its shipyard the items as
specified in the Specifications which the BUYER shall supply for its own account
(the "BUYER's Supplies") by the time designated by the SELLER.

        The delay in the delivery or the failure to deliver by the BUYER of any
BUYER's Supplies within the time specified shall not extend the Delivery Date.

        However, if the delay in delivery of the BUYER's Supplies should exceed
fifteen (15) days, the SELLER shall be entitled to proceed with construction of
the VESSEL without installation of such items in or onto the VESSEL and the
BUYER shall accept the VESSEL so completed.

        The BUILDER shall be responsible for storing and handling of the BUYER's
Supplies as specified in the Specifications after delivery to the BUILDER and
shall install them on board the VESSEL at the BUILDER's expenses.

VESSEL during the same. Failure of the BUYER's representatives to be present at
the Trial Run of the VESSEL, after due notice to the BUYER and the Supervisor as
provided above, shall have the effect to extend the date for delivery of the
VESSEL by the period of delay caused by such failure to be present. However, if
the Trial Run is delayed more than five (5) days by reason of the failure of the
BUYER's representatives to be present after receipt of due notice as provided
above (other than due to the failure by the BUYER's representative to obtain a
visa to enter China), then in such event, the BUYER shall be deemed to have
waived its right to have its representatives on board the VESSEL during the
Trial Run, and the BUILDER may conduct such Trial Run without the BUYER's
representatives being present, and in such case the BUYER shall be obliged to
accept the VESSEL on the basis of a certificate jointly signed by the BUILDER
and the Classification Society certifying that the VESSEL, after Trial Run
subject to minor alterations and corrections as provided in this Article, if
any, is found to conform to the Contract and Specifications and is satisfactory
in all respects. The SELLER hereby warrants that the necessary visa for the
BUYER's representatives to enter China will be issued in order on demand and
without delay otherwise the Trial Run shall be postponed until the BUYER's
representatives have arrived at the BUILDER's Shipyard. However, should the
nationalities and other personal particulars of the BUYER's representatives be
not acceptable to the SELLER in accordance with its best understanding of the
relevant rules, regulations and/or Laws of the People's Republic of China then
prevailing, then the SELLER shall so notify the BUYER and the BUYER shall
endeavor to effect the replacement of all or any of such representatives. The
Delivery Date as stipulated in Article VII hereof shall not be extended by any
delays caused by the BUYER's replacement of its representatives pursuant to the
SELLER's

request. In the event of unfavorable weather on the date scheduled for the Trial
Run, the same shall take place on the first available day thereafter that the
weather conditions permit. The parties hereto recognize that the weather
conditions in Chinese waters in which the Trial Run is to take place are such
that great changes in weather may arise momentarily and without warning and,
therefore, it is agreed that if during the Trial Run of the VESSEL, the weather
should suddenly become unfavorable, as would have precluded the continuance of
the Trial Run, the Trial Run of the VESSEL shall be discontinued and postponed
until the first favorable day next following, unless the BUYER assents in
writing by telex or telefax of its acceptance of the VESSEL on the basis of the
Trial Run made prior to such sudden change in weather conditions. In the event
that the Trial Run is postponed because of unfavorable weather conditions, the
Delivery Date shall not be extended other than pursuant to Article VIII hereof.

2.      HOW CONDUCTED

        (a) All expenses in connection with Trial Run of the VESSEL are to be

or Trial Runs as prescribed in the Specifications. The fuel oil supplied by the
SELLER, and lubricating oil, hydraulic oil and greases supplied by the BUYER
shall be in accordance with the applicable engine Specifications, and the cost
of the quantities of water, fuel oil, lubricating oil, hydraulic oil and greases
consumed during the Trial Run or Trial Runs shall be for the account of the
BUILDER.

account.

4.      METHOD OF ACCEPTANCE OR REJECTION

        (a) Upon notification of the BUILDER of the completion of the Trial Run
of the VESSEL attached with the trial result, the BUYER or the BUYER's
Supervisor shall within six (6) business days thereafter, notify the BUILDER in
writing by telex or telefax of its acceptance of the VESSEL or of its rejection
of the VESSEL together with the reasons therefor.

        (b) However, should the result of the Trial Run indicate that the VESSEL
or any part thereof including its equipment does not conform to the requirements
of this Contract and Specifications the BUILDER shall investigate with the
Supervisor the cause of failure and shall take proper steps to remedy the same
and shall make whatever corrections and alterations and/or re-Trial Run or Trial
Runs as may be necessary without extra cost to the BUYER, and upon notification
by the BUILDER of completion of such alterations or corrections and/or re-trial
or re-trials, the BUYER shall, within six (6) business days thereafter, notify
the SELLER in writing by telex or telefax of its acceptance of the VESSEL or of
its rejection of the VESSEL together with the reason therefor on the basis of
the alterations and corrections and/or re-Trial Run or re-Trial Runs by the
BUILDER.

        (c) In the event that the BUYER fails to notify the SELLER in writing by
telex or telefax of its acceptance or rejection of the VESSEL together with the
reason therefor within six (6) business days period as provided for in the above
sub-paragraphs (a) and (b), the BUYER shall be deemed to have accepted the
VESSEL.

        (d) Any dispute arising among the parties hereto as to the result of any
Trial Run or further tests or trials, as the case, may be, of the VESSEL shall
be referred to the Classification Society as provided in Article XIII Section 2
hereof.

        (e) Nothing herein shall preclude the BUYER from accepting the VESSEL
with its qualifications and/or remarks following the Trial Run and/or further
tests or trials as aforesaid and the SELLER shall be obliged to comply with
and/or remove such qualifications and/or remarks (if such qualifications and/or
remarks are acceptable to the SELLER) at the time before effecting delivery of
the VESSEL to the BUYER under this Contract.

5.      DISPOSITION OF SURPLUS CONSUMABLE STORES

        Should any amount of fuel oil, fresh water, or other unbroached
consumable stores furnished by the BUILDER for the Trial Run or Trial Runs
remain on board the VESSEL at the time of acceptance thereof by the BUYER, the
BUYER agrees to buy the same from the SELLER at the purchasing price at the port

the payment of the fifth installment, as provided in Article II, Section 4 of
this Contract.

        The BUYER shall supply lubricating oil, hydraulic oil and greases for
the purpose of Trial Runs at its own expenses and the SELLER will reimburse for

6.      EFFECT OF ACCEPTANCE

        The BUYER's acceptance of the VESSEL in writing by telex or telefax
notification sent to the SELLER, in accordance with the provisions set out
above, shall be final and binding so far as conformity of the VESSEL to this
Contract and the Specifications is concerned, and shall preclude the BUYER from
refusing Delivery (as defined below) by the SELLER of the VESSEL, as hereinafter
provided, if the SELLER complies with all other procedural requirements for
delivery as hereinafter set forth.

7.      GAS TRIAL

        (a) Prior to delivery of the VESSEL a running test of the equipment of
the Gas Plant and a function test of its system shall be carried out utilizing
either inert gas or dry air. These tests shall be repeated until its results are
deemed by the Classification Society and any other relevant authority to be in
conformity with this Contract and the Specifications, and the VESSEL shall not

the Specifications and the proper functioning of the Gas Plant as a whole is
secured.

        (f) All direct costs and expenses of remedying the non-conformity and
re-running the gas trial (including provision of suitable product, utilities and
consumables) shall be for the account of the SELLER.

        (g) If delays are incurred relating to the use of the VESSEL, caused by
an unsuccessful gas trial, remedial works and retrials for which the SELLER is
responsible, with the consequence that the classification certificate has not
been issued, will exceed more than twenty (20) days as from the commencement of
the Gas Trials, the SELLER shall, notwithstanding the provisions contained in
Article IX Section 2 and Section 4, pay to the BUYER as liquidated damages
United States Dollars Ten Thousand (US$10,000) for each day of such excess delay
up to a maximum amount of United States Dollars Two Hundred Thousand

                    DELAYS AND EXTENSION OF TIME FOR DELIVERY

1.      CAUSE OF DELAY

        If, at any time before actual Delivery, either the construction of the
VESSEL, or any performance required hereunder as a prerequisite of delivery of
the VESSEL, is delayed due to war, blockade, revolution, insurrection,
mobilization, civil commotions, riots, strikes, sabotage, lockouts, local
temperature higher than 35 degree centigrade, Acts of God or the public enemy,
plague or other epidemics, quarantines, prolonged failure or restriction of
electric current from an outside source, freight embargoes, if any, earthquakes,
tidal waves, typhoons, hurricanes, storms or other causes beyond the control of
the BUILDER or of its sub-contractors, as the case may be, or by force majeure
of any description, whether of the nature indicated by the forgoing or not, or
by destruction of the BUILDER or works of the BUILDER or its sub-contractors, or
of the VESSEL or any part thereof, by fire, flood, or other causes beyond the
control of the SELLER or its sub-contractors as the case may be, then, in the
event of delay due to the happening of any of the aforementioned contingencies,
the SELLER shall not be liable for such delay and the time for delivery of the
VESSEL under this Contract shall be extended without any reduction in the
Contract Price subject nevertheless to (i) the provisions of Section 1(a) of
Article III as to reduction in Contract Price, (ii) the BUYER's right of
termination under Section 1(a) of Article III and (iii) all relevant

provisions of this Contract which authorize and permit extension of the time of
delivery of the VESSEL.

2.      NOTICE OF DELAY

        Within fourteen (14) days from the date of commencement of any delay on
account of which the SELLER claims that it is entitled under this Contract to an
extension of the time for delivery of the VESSEL, the SELLER shall advise the
BUYER in writing by telex or telefax of the date such delay commenced, and
reasons therefor.

        Likewise within fourteen (14) days after such delay ends, the SELLER
shall advise the BUYER in writing by telex or telefax of the date such delay
ended, and also shall specify the maximum period of the time by which the date
for delivery of the VESSEL is extended by reason of such delay. Failure of the
BUYER to acknowledge the SELLER's notification of any claim for extension of the
Delivery Date within fourteen (14 ) days after receipt by the BUYER of such
notification, shall be deemed to be a waiver by the BUYER of its right to object
to such extension.

                                   ARTICLE IX
                               WARRANTY OF QUALITY

1.      GUARANTEE OF MATERIAL AND WORKMANSHIP

        The SELLER, for a period of twelve (12) months following delivery to the
BUYER of the VESSEL, guarantees the VESSEL, her hull and machinery and all parts
and equipment thereof that are manufactured or furnished or supplied by the
SELLER and/or its sub-contractors under this Contract including material,
equipment (however excluding any parts for the VESSEL which have been supplied
by or on behalf of the BUYER) against all defects which are due to defective
materials, and/or poor workmanship or failure to construct in conformity with
the Specifications.

2.      NOTICE OF DEFECTS

        The BUYER shall notify the SELLER in writing by telex or telefax, as
promptly as possible, after discovery of any defect or deviations for which a
claim is made under this guarantee. The BUYER's written notice shall describe
the nature of the defect and the extent of the damage caused thereby. The SELLER
shall have no obligation under this guarantee for any defects discovered prior
to the expiry date of the guarantee, unless notice of such defects is received
by the SELLER not later than thirty (30) days after such expiry date. Telexed or
telefaxed advice with brief details explaining the nature of such defect and
extent of damage within thirty (30) days

                                                     Shipbuilding Contract H2249

after such expiry date and that a claim is forthcoming will be sufficient to
comply with the requirements as to time.

3.      REMEDY OF DEFECTS

        The SELLER shall remedy at its expense any defect, against which the
VESSEL or any part of the equipment thereof is guaranteed under this Article by
making all necessary repairs and/or replacement. Such repairs and/or replacement
will be made by the SELLER.

        However, if it is impractical to make the repair by the SELLER, and if
forwarding by the SELLER of replacement part, and materials cannot be
accomplished without impairing or delaying the operation of the VESSEL, then, in
any such event, the BUYER shall cause the necessary repairs or replacements to
be made elsewhere at the discretion of the BUYER provided that the BUYER shall,
as soon as possible, give the SELLER notice in writing by telex or telefax of
the time and place such repairs will be made, provided always that the burden of
proof as to the necessity for such repairs and replacements shall rest with the
BUYER, and a written confirmation for such repairs or replacement shall be
obtained from the SELLER. Defects that affect the safety of the VESSEL or her
crew and/or constitute an emergency shall be repaired either by the crew or a
BUYER selected contractor in a manner reasonable under the circumstances without
the SELLER's prior approval and the SELLER shall be notified as to the nature
and extent of repairs as soon as possible after the repairs are undertaken and
such repair work will be subject to the mutual agreement between the parties. If
the VESSEL is not thereby delayed or her operation is not thereby delayed or
impaired, the SELLER shall have the right to verify the nature and extent of the
defects complained of by its own representative(s) or that of Classification
Society. The SELLER shall, in such cases, promptly advise the BUYER, by telex or
telefax, after such examination has been completed, of its acceptance or
rejection of the defects as ones justifying the remedy under this Article. In

                  In the event the VESSEL shall be damaged by any insured cause
        whatsoever prior to acceptance and delivery thereof by the BUYER and in
        the further event that such damage shall not constitute an actual or a
        constructive total loss of the VESSEL, the SELLER shall apply the amount

                  hereto, proceed in accordance with terms of this Contract, in
                  which case the amount recovered under said insurance policy
                  shall be applied to the reconstruction and/or repair of the
                  VESSEL's damages and/or reinstallation of BUYER's supplies
                  without additional expenses to the BUYER, provided the parties
                  hereto shall have first agreed in writing as to such
                  reasonable extension of the Delivery Date and adjustment of
                  other terms of this Contract including the Contract Price as
                  may be necessary for the completion of such reconstruction; or

                          (ii) If due to whatever reasons the parties fail to
                  agree on the above, then the BUYER shall deliver a written
                  notice of rejection to SELLER and the SELLER shall refund
                  immediately to the BUYER the amount described in Article II,
                  Section 7, whereupon this Contract shall be deemed to be

                  of each of the parties to the other shall terminate forthwith.

                          (iii) Notwithstanding the provisions of (i) and (ii)
                  above, Seller may elect to postpone delivery of the Vessel
                  subject to the provisions of Article III, Section (1)(a).

                  Within thirty (30) days after receiving telex or telefax
        notice of any damage to the VESSEL constituting an actual or a
        constructive total loss, the BUYER shall notify the SELLER in writing or
        by telex of its agreement or disagreement under this sub-paragraph. In
        the event the BUYER fails to so notify the SELLER, then such failure
        shall be construed as a disagreement on the part of the BUYER. This
        Contract shall be deemed as rescinded and canceled and the BUYER shall
        receive the refund as hereinabove provided and the provisions hereof
        shall apply.

        Should any dispute of any nature arise in respect of this Contract, its
performance or interpretation which is not decided in accordance with Article
XIII, Section 2 below, such dispute shall be settled by arbitration in London,
England in accordance with the rules of the London Maritime Arbitrators
Association Inc. and otherwise in accordance with the provisions of the Laws of
England. The party who desires arbitration of any such dispute shall give
written notice to the other party. The notice shall state the name and address
of the arbitrator whom it appoints and describe the specific nature of the
particular dispute. Such notice shall be sent by registered air mail and shall
be addressed in the manner set forth in Article XIX, and the other party shall,
within thirty (30) days following the receipt of said notice, give written
notice to the party requesting the arbitration as to the name and address of the
arbitrator whom it appoints, which notice shall be sent by registered air mail
and shall be addressed in the manner set forth in Article XIX, provided that if
the other party should fail to so appoint its arbitrator, the arbitrator
appointed by the party desiring the arbitration may proceed with the arbitration
hearing and issue an award. Otherwise the two arbitrators so chosen shall select
a third arbitrator. The applicable law of England on all matters at issue shall
apply. A judgement based upon the decision of the majority of the arbitrators or
the sole arbitrator, as the case may be, may be entered in the appropriate court
of any country having jurisdiction of either party. The arbitrators shall also
decide which party, or the extent to which each party, shall pay costs of
arbitration. Unless and to the extent otherwise determined by the arbitrator(s),
reference to arbitration shall not relieve the BUILDER of its obligation
diligently to proceed with the construction, completion and delivery of the
VESSEL, but the majority of the arbitrators or the sole arbitrator, as the case
may be, shall decide the extent to which the Delivery Date shall be extended by
virtue of the dispute having been referred to arbitration.

recognized that in the event of any dispute or difference of opinion arising in
regard to the construction of the VESSEL, her machinery and equipment, or
concerning the quality of materials or workmanship thereof or thereon, such
dispute may be referred to the Classification Society upon mutual agreement of
the parties hereto. In such case, the opinion of the Classification Society
shall be final and binding on the parties hereto.

3.      NOTICE OF AWARD

        Notice of any award shall immediately be given in writing or by telex
confirmed in writing to the SELLER and the BUYER.

Dear Sirs:

At the request of China Shipbuilding Trading Company, Limited ("CSTC") and

installments of the contract price (the "Contract Price") pursuant to the
Amended and Restated Shipbuilding Contract dated the 26th day of June, 1997, as
amended, supplemented or otherwise modified from time to time (hereinafter

construction of one (1) 22,000 cubic meter liquefied ethylene gas carrier having
Hull No. 2249 (hereinafter called the "VESSEL"), The Export Import Bank of China
the "Bank") the undersigned, do guarantee the payment (and not merely the
collectability of the same) to the BUYER by the SELLER immediately upon demand
of an amount up to but not exceeding a total amount as set forth in Schedule 1

together with simple interest thereon calculated at the rate of ten percent

                                                     Shipbuilding Contract H2249

between (1) the amount set forth on Schedule 1 hereto calculated as of the first
day of the calendar month immediately succeeding the month in which the Date of
Rejection occurs and (2) the amount set forth on Schedule 1 hereto as of the

Contract occurs and (y) a fraction the numerator of which is numeric day of the
month of the date on which the Refund Amount (as hereinafter defined) is
actually paid and the denominator of which is 30 (collectively, the "Refund
Amount").

BUYER's right to demand payment under this Guarantee shall become effective on
the earlier to occur of (i) April 1, 2001, (ii) the date on which the SELLER
fails to pay any liquidated damages payable to BUYER as provided in Section 1(a)
of Article III of the Contract, (iii) upon the cancellation, termination or
rescission of the Contract by the BUYER in accordance with the terms of Contract
as set forth in Article III, 1(a), 2(c), 3(c), 4(c), 5(c), Article X, Article
XII 2(b), or Article XVI (b) or (c), or (iv) the insolvency or bankruptcy of
BUILDER.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to us by the BUYER.

Payment under this Guarantee is available at the counters of ______________ Bank
against presentation of the BUYER's signed statement issued in the form attached
hereto as Appendix A ("Notice of Demand"). If the Notice of Demand is received

Refund Amount (plus interest thereon) in immediately available funds within ten
(10) banking days. If the Notice of Demand is received by the Bank after 12:00

This Guarantee is available for one payment only, whether for the full amount
hereof or any part thereof, as may be demanded by the BUYER. In the event that
the BUYER's demand is for a lesser amount than the amount of this Guarantee, the
interest payable will be calculated on the amount of the BUYER's demand and not
on the amount of this Guarantee.

We agree that this Guarantee shall be a continuing guarantee and (i) shall not
be impaired or discharged by the granting of time or any other indulgence to the
SELLER, or any other forbearance (whether as to payment, time, performance, or
otherwise) which might, but for this provision, have any such effect; (ii) shall
not be conditioned or contingent upon the BUYER's pursuit of any remedy that it
has against the SELLER; and (iii) shall be unconditional irrespective of any
other circumstance that might otherwise constitute a legal or equitable
discharge of a surety or guarantor under

applicable law, and we hereby waive any and all rights (whether by counterclaim,
set off or otherwise) and defenses at law or in equity that may be available to
us by reason of such circumstance.

This Guarantee shall become effective from the time of the actual receipt of the
first installment by the SELLER from the BUYER under the Contract and the Refund
Amount payable under this Guarantee shall correspond to the total installment
payments actually made by the BUYER to the SELLER from time to time under the
Contract prior to the delivery of the VESSEL including applicable interest.

This Guarantee shall expire and become null and void on the earlier to occur of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
the Bank of either a copy of the Protocol of Delivery and Acceptance of the
VESSEL, purportedly signed by the BUYER and the SELLER and issued in the form

its obligations hereunder shall continue to be effective or reinstated, as the
case may be, if at any time any payment, or any part thereof, made by the SELLER
is rescinded or must otherwise be restored by the BUYER upon the bankruptcy or
reorganization of the SELLER.

Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER confirmed by an arbitrator stating that the BUYER's
claim to cancel the Contract or the BUYER's claim for refundment thereunder has
been disputed and referred to arbitration in accordance with the provisions of
the Contract, the period of validity of this Guarantee shall be extended until
thirty (30) days after the final award shall be rendered in the arbitration and
a copy thereof acknowledged by the arbitrators. In such case, this Guarantee
shall not be available unless and until such acknowledged copy of the final
award in the Arbitration justifying the BUYER's claim is presented to us;
subject to any appeal of such final award which may be permitted under English
law; provided the Refund Amount shall be adjusted to reflect the delay resulting
from such arbitration and shall be calculated in accordance with Schedule 1
hereto to the date payment is actually made.

Dear Sirs:

At the request of China Shipbuilding Trading Company, Limited ("CSTC") and
Jiangnan Shipyard (the "Builder" and together with CSTC collectively called the
"SELLER") and in consideration of Navigator Holdings, PLC (the "BUYER") agreeing
to pay SELLER the installments of the contract price (the "Contract Price")
pursuant to the Amended and Restated Shipbuilding Contracts dated the 26th day
of June, 1997, as amended, supplemented or otherwise modified from time to time
(hereinafter called the "Contracts") made by and between the BUYER and the
SELLER for the construction of five (5) 22,000 cubic meter liquefied ethylene
gas carriers respectively having Hull Nos. 2245, 2246, 2247, 2248 and 2249
(hereinafter called the "VESSELS"), Export-Import Bank of China (the "Bank")
guarantees the payment (and not merely the collectability of the same) to the
BUYER by the SELLER, immediately upon demand, of an amount up to but not
exceeding a total aggregate amount of United States Dollars Twenty Six Million
Seven Hundred Thousand (US$26,700,000) (the "Payment Amount"), if and when the
same or any part thereof becomes payable to BUYER from the SELLER under any
Contract or Contracts if any such Contract or Contracts are cancelled by the
BUYER in accordance with the terms (Article III, 1(a), 2(c), 3(c), 4(c), 5(c),
Article X, Article XII 2(b) and Article XVI (b) and (c)) of such Contract or
Contracts (any a "Cancellation Event"). This Performance Bond shall become
effective upon actual receipt in full by the SELLER of the initial installment
due under each of the Contracts.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to the BANK by the BUYER.

                                                        Amended and Restated
                                                     Shipbuilding Contract H2249

Payment under this Performance Bond is available at the counters of
Export-Import Bank of China in __________________ against presentation of the
BUYER's signed statement issued in the form attached hereto as Appendix A
("Notice of Demand"). The Notice of Demand shall set forth the dollar amount to
be paid to the BUYER under this Performance Bond, which amount shall be based
upon Schedule 1 attached hereto (the "Demand Amount") provided such Demand
Amount shall not exceed the Payment Amount. As to any date on which a Notice of
Demand is presented, the Demand Amount shall be equal to the amount set forth
opposite the calendar month in which such Notice of Demand is presented under
the column heading specified in the Notice of Demand. If the Notice of Demand is
received by the Bank by 12:00 noon local time on a banking day, the Bank shall
pay the Demand Amount in immediately available funds within ten (10) banking
days. If the Notice of Demand is received by the Bank after 12:00 noon local
time on a banking day, the Bank shall pay the Demand Amount in immediately
available funds within eleven (11) banking days.

The right of the BUYER to demand payment under this Performance Bond by
presentation of a Notice of Demand shall become effective on the earlier to
occur of (i) April 1, 2001, (ii) the date on which the SELLER fails to pay any
liquidated damages payable to BUYER as provided in Section 1(a) of Article III
of the Contracts, (iii) the occurrence of a Cancellation Event or (iv) the
bankruptcy or insolvency of the Builder.

This Performance Bond is available for one payment only, whether for the full
amount hereof or any part thereof, as may be demanded by the BUYER.

We agree that this Performance Bond shall be a continuing guarantee and (i)
shall not be impaired or discharged by the granting of time or any other
indulgence to the SELLER, or any other forbearance (whether as to payment, time,
performance, or otherwise) which might, but for this provision, have any such
effect; (ii) shall not be conditioned or contingent upon the BUYER's pursuit of
any remedy that it has against the SELLER; and (iii) shall be unconditional
irrespective of any other circumstance that might otherwise constitute a legal
or equitable discharge of a surety or guarantor under applicable law, and we
hereby waive any and all rights (whether by counterclaim, set off or otherwise)
and defenses at law or in equity that may be available to us by reason of such
circumstance.

This Performance Bond shall expire and become null and void on the earlier of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
Bank of a copy of the Protocol of Acceptance and Delivery or Certificates of
Completion for each of the five (5) VESSELS in the form of Appendix B or
Appendix C to this Performance Bond; or (iii) 5:00 p.m. New York time on May 1,
2001, in any such case this Performance Bond shall be returned to us; provided,
the Bank further agrees that its obligations hereunder shall continue to be
effective or reinstated, as the case may be, if at any time any payment, or any
part thereof, made by the SELLER is

rescinded or must otherwise be restored by the BUYER upon the bankruptcy or
reorganization of the SELLER.

Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER stating that the BUYER's claim to cancel the Contracts
or the BUYER's claim for payment thereunder has been disputed and referred to
arbitration in accordance with the provisions of the Contracts, the period of
validity of this Performance Bond shall be extended until thirty (30) days after
the final award shall be rendered in the arbitration and a copy thereof
acknowledged by the arbitrators. In such case, this Performance Bond shall not
be available unless and until such acknowledged copy of the final award in the
Arbitration justifying the BUYER's claim is presented to us; subject to any
appeal of such final award which may be permitted under English law.

Dear Sirs:

At the request of Tractebel Gas Engineering GmBH and in consideration of
Navigator Holdings, PLC (the "BUYER") agreeing to pay China Shipbuilding Trading
Company, Limited ("CSTC") and Jiangnan Shipyard (the "Builder" together with
CSTC collectively called the "SELLER") the installments of the contract price
(the "Contract Price") pursuant to the Amended and Restated Shipbuilding
Contracts dated the 26th day of June, 1997, as amended, supplemented or
otherwise modified from time to time (hereinafter called the "Contracts") made
by and between the BUYER and the SELLER for the construction of five (5) 22,000
cubic meter liquefied ethylene gas carriers having Hull Nos. 2245, 2246, 2247,
2248 and 2249 (hereinafter called the "VESSELS"), Generale de Banque (the
"Bank") guarantees the payment (and not merely the collectability of the same)
to the BUYER by the SELLER, immediately upon demand, of an amount up to but not
exceeding a total aggregate amount of United States Dollars Thirteen Million
Three Hundred Thousand (US$13,300,000) (the "Payment Amount"), if and when the
same or any part thereof become payable to BUYER from the SELLER under any
Contract or Contracts if any such contract or contracts are cancelled by the
BUYER in accordance with the terms (Article III, 1(a), 2(c), 3(c), 4(c), 5(c),
Article X, Article XII 2(b) and Article XVI(b) and (c)) of the Contracts (any a
"Cancellation Event"). This Performance Bond shall become effective upon payment
of the initial installment under each of the Contracts.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to the BANK by the BUYER.

Payment under this Performance Bond is available at the counters of
_______________ against presentation of the BUYER's signed statement issued in
the form attached hereto as Appendix A ("Notice of Demand"). The Notice of
Demand shall set forth the dollar amount to be paid to the BUYER under this
Performance Bond, which amount shall be based upon Schedule 1


                                       C-1
<PAGE>

attached hereto (the "Demand Amount") provided such Demand Amount shall not
exceed the Payment Amount. As to any date on which a Notice of Demand is
presented, the Demand Amount shall be equal to the amount set forth opposite the
calendar month in which such Notice of Demand is presented and under the column
heading specified in the Notice of Demand less the amount paid by the
Export-Import Bank of China under such Bank's Irrevocable Performance Bond dated
_______, 1997 (the "Ex-Im Performance Bond"). In addition, the BUYER's right to
demand payment as provided above is subject to delivery by BUYER to the Bank of
a copy of the notice of demand presented to the Export-Import Bank of China
under the Ex-Im Performance Bond in the amount of US$26,700,000 and evidence
that such amount has been paid.

If the Notice of Demand is received by the Bank by 12:00 noon local time on a
business day, the Bank shall pay the Demand Amount in immediately available
funds on the same business day. If the Notice of Demand is received by the Bank
after 12:00 noon local time on a business day, the Bank shall pay the Demand
Amount in immediately available funds on the next succeeding business day.

The right of the BUYER to demand payment under this Performance Bond shall
become effective on the earlier to occur of (i) April 1, 2001, (ii) the date on
which the SELLER fails to pay any liquidated damages payable to BUYER as
provided in Section 1(a) of Article III of the Contracts, (iii) the occurrence
of a Cancellation Event or (iv) the bankruptcy or insolvency of the Builder.

This Performance Bond is available for one payment only, whether for the full
amount hereof or any part thereof, as may be demanded by the BUYER.

We agree that this Performance Bond shall be a continuing guarantee and (i)
shall not be impaired or discharged by the granting of time or any other
indulgence to the SELLER, or any other forbearance (whether as to payment, time,
performance, or otherwise) which might, but for this provision, have any such
effect; (ii) shall not be conditioned or contingent upon the BUYER's pursuit of
any remedy that it has against the SELLER; and (iii) shall be unconditional
irrespective of any other circumstance that might otherwise constitute a legal
or equitable discharge of a surety or guarantor under applicable law, and we
hereby waive any and all rights (whether by counterclaim, set off or otherwise)
and defenses at law or in equity that may be available to us by reason of such
circumstance.

This Performance Bond shall expire and become null and void on the earlier of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
Bank of a copy of the Protocol of Acceptance and Delivery and/or Certificates of
Completion for each of the five (5) VESSELs in the form of Appendix B or
Appendix C to this Performance Bond; and (iii) 5:00 p.m. New York time on May 1,
2001, in any such case this Performance Bond shall be returned to us; provided,
the Bank further agrees that its obligations hereunder shall continue to be
effective or reinstated, as the case may be, if at any time any payment, or any
part thereof, made by the


                                       C-2
<PAGE>

SELLER is rescinded or must otherwise be restored by the BUYER upon the
bankruptcy or reorganization of the SELLER.



Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER confirmed by an arbitrator stating that the BUYER's
claim to cancel the Contracts or the BUYER's claim for refundment thereunder has
been disputed and referred to arbitration in accordance with the provisions of
the Contract, the period of validity of this Performance Bond shall be extended
until thirty (30) days after the final award shall be rendered in the
arbitration and a copy thereof acknowledged by the arbitrators. In such case,
this Performance Bond shall not be available unless and until such acknowledged
copy of the final award in the Arbitration justifying the BUYER's claim is
presented to us; subject to any appeal of such final award which may be
permitted under English law.

This Performance Bond is governed by and enforced and construed in accordance
with the laws of England.

               AMENDMENT No. 1 made as of this 1st day of August, 1997 (this
"AMENDMENT") to the AMENDED AND RESTATED SHIPBUILDING CONTRACT (the
"SHIPBUILDING CONTRACT") dated as of June 26, 1997 among Navigator Gas (IOM I-A)
Limited as assignee of Navigator Holdings PLC's rights, title and interest (the
"BUYER") and China Shipbuilding Trading Company, Limited and Jiangnan Shipyard
(collectively, as "SELLER") for construction of one (1) 22,000 Cubic Meters
Liquified Ethylene Gas Carrier (Hull No. 2245). Capitalized terms used and not
otherwise defined herein shall have the respective meanings set forth in the
SHIPBUILDING CONTRACT.

               WHEREAS, the BUYER and SELLER desire to amend certain terms and
schedules of the SHIPBUILDING CONTRACT to and in accordance with Section 7 of
Article XXI of the SHIPBUILDING CONTRACT for the purpose of correcting
provisions therein which have resulted from the increased cost of borrowing
incurred by the BUYER to finance the acquisition of the Vessel;

                           NOW, THEREFORE, in consideration of the foregoing,
BUYER and SELLER agree as follows:


               1. Section 7(a) of Article II of the SHIPBUILDING CONTRACT is
hereby deleted in its entirety and is hereby amended to read as follows:

               "(a) All payments made by the BUYER hereunder in United States
Dollars and prior to Delivery and BUYER's acceptance of the VESSEL shall be in
the nature of installments to the SELLER. In the event that, the VESSEL is
rejected by the BUYER, or this Contract is canceled or terminated by the BUYER,
all in accordance with the terms of this Contract, or if the SELLER should
default in Delivery of the VESSEL or is guilty of breach of this Contract
justifying a rescission thereof by the BUYER then, and in any such event, the
SELLER shall refund to the BUYER an amount equal to the sum of the following:

                                    (i) the amounts set forth in Schedule 2
                           hereto calculated as of the first day of the calendar
                           month in which the Date of Rejection occurs,

                                    (ii) an amount equal to the product of (x)
                           the difference between (1) the amount set forth on
                           Schedule 2 hereto calculated as of the first day of
                           the calendar month immediately succeeding the month
                           in which the Date of Rejection occurs and (2) the
                           amount set forth on Schedule 2 hereto as of the first
                           day of the month in which the Date of Rejection
                           occurs and (y) a fraction the numerator of which is
                           the numeric day of the month of the Date of Rejection
                           and the denominator of which is 30, and

                                    (iii) the amount set forth on Schedule 3
                           hereto calculated as of the calendar month in which
                           the Date of Rejection occurs.


<PAGE>

If the amount as calculated above is not paid on the Date of Rejection there
shall be added to such amount interest at the rate of eleven percent (11.0%) per
annum from and including the Date of Rejection to but not including the date
such amount is paid. Such refunds by the SELLER to the BUYER shall forthwith
discharge all obligations, duties, and liabilities of each of the parties hereto
to the other under this Contract. Any and all refunds made to the BUYER under
this Article II, Section 7 shall be made in United States Dollars. Throughout
this Contract, whenever interest is due on any amounts to be paid or refunded by
either party, said interest shall be calculated as simple interest, based on the
actual number of days divided by 360.

               For purposes of this Section 7(a) Date of Rejection means the
date on which written notice of rejection, cancellation or rescission is
delivered by BUYER to SELLER.

               All refunds made by the SELLER to the BUYER under this contract
shall be paid in United States Dollars by telegraphic transfer to the BUYER's
account or its assignee's account as set forth in a written notice to the SELLER
from such party."

               2. Section 1(a)(ii) of Article III of the SHIPBUILDING CONTRACT
is hereby deleted in its entirety and is hereby amended to read as follows:

                           "(ii) If the Delivery is not made on the Original
               Delivery Date (subject to a Permissible Delay as defined below),
               the SELLER shall pay the BUYER, as liquidated damages (not as
               penalty), the amount of $11,000 for each calendar day for the
               first ninety (90) calendar days of delay beyond the Extended
               Delivery Date (as hereinafter defined) and the amount of $14,500
               for each calendar day of delay thereafter up to and including the
               210th day from the Original Delivery Date ("Original Delay
               Period"). Liquidated damages calculated with respect to the
               Original Delay Period shall be recovered by the BUYER through a
               reduction in the Fifth Installment payable by the BUYER to the
               SELLER in an amount equal to such Liquidated Damages."

               3. Section 3(a) of Article XI of the SHIPBUILDING CONTRACT is
hereby deleted in its entirety and is hereby amended to read as follows:

               "(a) If the BUYER is in default of payment as to any installment
as provided in Paragraph 1 (a) and/or 1 (b) of this Article, the BUYER shall pay
interest on such installment at the rate of eleven percent (11.0%) per annum
until the date of the payment of the full amount, including all aforesaid
interest. In case the BUYER shall fail to take delivery of the VESSEL when
required to as provided in Section 1 (c) of this Article, the BUYER shall be
deemed in default of payment of the fifth installment and shall pay interest
thereon at the same rate as aforesaid from and including the day on which the
VESSEL is tendered for delivery by the SELLER, as provided in Article VII
Section 6 hereof."

               4. Schedule 2 of the SHIPBUILDING CONTRACT is hereby deleted in
its entirety and Schedule 2 attached hereto shall be attached as Schedule 2 to
the SHIPBUILDING CONTRACT.

               5. Schedule 3 of the SHIPBUILDING CONTRACT is hereby deleted in
its entirety and Schedule 3 attached hereto shall be attached as Schedule 3 to

deleted in its entirety and Schedule 1 to Exhibit A attached hereto shall be
attached as Schedule 1 to Exhibit A to the SHIPBUILDING CONTRACT.

               7. The parties hereto agree that the validity, enforcement and
interpretation of this AMENDMENT and of each Article and part hereof be governed
by and interpreted in accordance with the Laws of England.

               8. This AMENDMENT has been prepared in the English language,

Cambridge Partners, L.L.C.                                                 FINAL




               AMENDMENT No. 1 made as of this 1st day of August, 1997 (this
"AMENDMENT") to the AMENDED AND RESTATED SHIPBUILDING CONTRACT (the
"SHIPBUILDING CONTRACT") dated as of June 26, 1997 among Navigator Gas (IOM I-B)
Limited as assignee of Navigator Holdings PLC's rights, title and interest (the
"BUYER") and China Shipbuilding Trading Company, Limited and Jiangnan Shipyard
(collectively, as "SELLER") for construction of one (1) 22,000 Cubic Meters
Liquified Ethylene Gas Carrier (Hull No. 2246). Capitalized terms used and not
otherwise defined herein shall have the respective meanings set forth in the
SHIPBUILDING CONTRACT.

               WHEREAS, the BUYER and SELLER desire to amend certain terms and
schedules of the SHIPBUILDING CONTRACT to and in accordance with Section 7 of
Article XXI of the SHIPBUILDING CONTRACT for the purpose of correcting
provisions therein which have resulted from the increased cost of borrowing
incurred by the BUYER to finance the acquisition of the Vessel;

                           NOW, THEREFORE, in consideration of the foregoing,
BUYER and SELLER agree as follows:


1. Section 7(a) of Article II of the SHIPBUILDING CONTRACT is hereby deleted in
its entirety and is hereby amended to read as follows:

               "(a) All payments made by the BUYER hereunder in United States
Dollars and prior to Delivery and BUYER's acceptance of the VESSEL shall be in
the nature of installments to the SELLER. In the event that, the VESSEL is
rejected by the BUYER, or this Contract is canceled or terminated by the BUYER,
all in accordance with the terms of this Contract, or if the SELLER should
default in Delivery of the VESSEL or is guilty of breach of this Contract
justifying a rescission thereof by the BUYER then, and in any such event, the
SELLER shall refund to the BUYER an amount equal to the sum of the following:

                                    (i) the amounts set forth in Schedule 2
                           hereto calculated as of the first day of the calendar
                           month in which the Date of Rejection occurs,

                                    (ii) an amount equal to the product of (x)
                           the difference between (1) the amount set forth on
                           Schedule 2 hereto calculated as of the first day of
                           the calendar month immediately succeeding the month
                           in which the Date of Rejection occurs and (2) the
                           amount set forth on Schedule 2 hereto as of the first
                           day of the month in which the Date of Rejection
                           occurs and (y) a fraction the numerator of which is
                           the numeric day of the month of the Date of Rejection
                           and the denominator of which is 30, and

                                    (iii) the amount set forth on Schedule 3
                           hereto calculated as of the calendar month in which
                           the Date of Rejection occurs.


<PAGE>


If the amount as calculated above is not paid on the Date of Rejection there
shall be added to such amount interest at the rate of eleven percent (11.0%) per
annum from and including the Date of Rejection to but not including the date
such amount is paid. Such refunds by the SELLER to the BUYER shall forthwith
discharge all obligations, duties, and liabilities of each of the parties hereto
to the other under this Contract. Any and all refunds made to the BUYER under
this Article II, Section 7 shall be made in United States Dollars. Throughout
this Contract, whenever interest is due on any amounts to be paid or refunded by
either party, said interest shall be calculated as simple interest, based on the
actual number of days divided by 360.

               For purposes of this Section 7(a) Date of Rejection means the
date on which written notice of rejection, cancellation or rescission is
delivered by BUYER to SELLER.

               All refunds made by the SELLER to the BUYER under this contract
shall be paid in United States Dollars by telegraphic transfer to the BUYER's
account or its assignee's account as set forth in a written notice to the SELLER
from such party."

               2. Section 1(a)(ii) of Article III of the SHIPBUILDING CONTRACT
is hereby deleted in its entirety and is hereby amended to read as follows:

                           "(ii) If the Delivery is not made on the Original
               Delivery Date (subject to a Permissible Delay as defined below),
               the SELLER shall pay the BUYER, as liquidated damages (not as
               penalty), the amount of $11,000 for each calendar day for the
               first ninety (90) calendar days of delay beyond the Extended
               Delivery Date (as hereinafter defined) and the amount of $14,500
               for each calendar day of delay thereafter up to and including the
               210th day from the Original Delivery Date ("Original Delay
               Period"). Liquidated damages calculated with respect to the
               Original Delay Period shall be recovered by the BUYER through a
               reduction in the Fifth Installment payable by the BUYER to the
               SELLER in an amount equal to such Liquidated Damages."

               3. Section 3(a) of Article XI of the SHIPBUILDING CONTRACT is
hereby deleted in its entirety and is hereby amended to read as follows:

               "(a) If the BUYER is in default of payment as to any installment
as provided in Paragraph 1 (a) and/or 1 (b) of this Article, the BUYER shall pay
interest on such installment at the rate of eleven percent (11.0%) per annum
until the date of the payment of the full amount, including all aforesaid
interest. In case the BUYER shall fail to take delivery of the VESSEL when
required to as provided in Section 1 (c) of this Article, the BUYER shall be
deemed in default of payment of the fifth installment and shall pay interest
thereon at the same rate as aforesaid from and including the day on which the
VESSEL is tendered for delivery by the SELLER, as provided in Article VII
Section 6 hereof."

               4. Schedule 2 of the SHIPBUILDING CONTRACT is hereby deleted in
its entirety and Schedule 2 attached hereto shall be attached as Schedule 2 to
the SHIPBUILDING CONTRACT.

deleted in its entirety and Schedule 1 to Exhibit A attached hereto shall be

               7. The parties hereto agree that the validity, enforcement and
interpretation of this AMENDMENT and of each Article and part hereof be governed
by and interpreted in accordance with the Laws of England.

Cambridge Partners, L.L.C.                                                 FINAL




               AMENDMENT No. 1 made as of this 1st day of August, 1997 (this
"AMENDMENT") to the AMENDED AND RESTATED SHIPBUILDING CONTRACT (the
"SHIPBUILDING CONTRACT") dated as of June 26, 1997 among Navigator Gas (IOM I-C)
Limited as assignee of Navigator Holdings PLC's rights, title and interest (the
"BUYER") and China Shipbuilding Trading Company, Limited and Jiangnan Shipyard
(collectively, as "SELLER") for construction of one (1) 22,000 Cubic Meters
Liquified Ethylene Gas Carrier (Hull No. 2247). Capitalized terms used and not
otherwise defined herein shall have the respective meanings set forth in the
SHIPBUILDING CONTRACT.

               WHEREAS, the BUYER and SELLER desire to amend certain terms and
schedules of the SHIPBUILDING CONTRACT to and in accordance with Section 7 of
Article XXI of the SHIPBUILDING CONTRACT for the purpose of correcting
provisions therein which have resulted from the increased cost of borrowing
incurred by the BUYER to finance the acquisition of the Vessel;

                           NOW, THEREFORE, in consideration of the foregoing,
BUYER and SELLER agree as follows:


               1. Section 7(a) of Article II of the SHIPBUILDING CONTRACT is
hereby deleted in its entirety and is hereby amended to read as follows:

               "(a) All payments made by the BUYER hereunder in United States
Dollars and prior to Delivery and BUYER's acceptance of the VESSEL shall be in
the nature of installments to the SELLER. In the event that, the VESSEL is
rejected by the BUYER, or this Contract is canceled or terminated by the BUYER,
all in accordance with the terms of this Contract, or if the SELLER should
default in Delivery of the VESSEL or is guilty of breach of this Contract
justifying a rescission thereof by the BUYER then, and in any such event, the
SELLER shall refund to the BUYER an amount equal to the sum of the following:

                                    (i) the amounts set forth in Schedule 2
                           hereto calculated as of the first day of the calendar
                           month in which the Date of Rejection occurs,

                                    (ii) an amount equal to the product of (x)
                           the difference between (1) the amount set forth on
                           Schedule 2 hereto calculated as of the first day of
                           the calendar month immediately succeeding the month
                           in which the Date of Rejection occurs and (2) the
                           amount set forth on Schedule 2 hereto as of the first
                           day of the month in which the Date of Rejection
                           occurs and (y) a fraction the numerator of which is
                           the numeric day of the month of the Date of Rejection
                           and the denominator of which is 30, and

                                    (iii) the amount set forth on Schedule 3
                           hereto calculated as of the calendar month in which
                           the Date of Rejection occurs.


<PAGE>

If the amount as calculated above is not paid on the Date of Rejection there
shall be added to such amount interest at the rate of eleven percent (11.0%) per
annum from and including the Date of Rejection to but not including the date
such amount is paid. Such refunds by the SELLER to the BUYER shall forthwith
discharge all obligations, duties, and liabilities of each of the parties hereto
to the other under this Contract. Any and all refunds made to the BUYER under
this Article II, Section 7 shall be made in United States Dollars. Throughout
this Contract, whenever interest is due on any amounts to be paid or refunded by
either party, said interest shall be calculated as simple interest, based on the
actual number of days divided by 360.

               For purposes of this Section 7(a) Date of Rejection means the
date on which written notice of rejection, cancellation or rescission is
delivered by BUYER to SELLER.

               All refunds made by the SELLER to the BUYER under this contract
shall be paid in United States Dollars by telegraphic transfer to the BUYER's
account or its assignee's account as set forth in a written notice to the SELLER
from such party."

               2. Section 1(a)(ii) of Article III of the SHIPBUILDING CONTRACT
is hereby deleted in its entirety and is hereby amended to read as follows:

                           "(ii) If the Delivery is not made on the Original
               Delivery Date (subject to a Permissible Delay as defined below),
               the SELLER shall pay the BUYER, as liquidated damages (not as
               penalty), the amount of $11,000 for each calendar day for the
               first ninety (90) calendar days of delay beyond the Extended
               Delivery Date (as hereinafter defined) and the amount of $14,500
               for each calendar day of delay thereafter up to and including the
               210th day from the Original Delivery Date ("Original Delay
               Period"). Liquidated damages calculated with respect to the
               Original Delay Period shall be recovered by the BUYER through a
               reduction in the Fifth Installment payable by the BUYER to the
               SELLER in an amount equal to such Liquidated Damages."

               3. Section 3(a) of Article XI of the SHIPBUILDING CONTRACT is
hereby deleted in its entirety and is hereby amended to read as follows:

               "(a) If the BUYER is in default of payment as to any installment
as provided in Paragraph 1 (a) and/or 1 (b) of this Article, the BUYER shall pay
interest on such installment at the rate of eleven percent (11.0%) per annum
until the date of the payment of the full amount, including all aforesaid
interest. In case the BUYER shall fail to take delivery of the VESSEL when
required to as provided in Section 1 (c) of this Article, the BUYER shall be
deemed in default of payment of the fifth installment and shall pay interest
thereon at the same rate as aforesaid from and including the day on which the
VESSEL is tendered for delivery by the SELLER, as provided in Article VII
Section 6 hereof."

               4. Schedule 2 of the SHIPBUILDING CONTRACT is hereby deleted in
its entirety and Schedule 2 attached hereto shall be attached as Schedule 2 to
the SHIPBUILDING CONTRACT.

               5. Schedule 3 of the SHIPBUILDING CONTRACT is hereby deleted in

deleted in its entirety and Schedule 1 to Exhibit A attached hereto shall be

               7. The parties hereto agree that the validity, enforcement and
interpretation of this AMENDMENT and of each Article and part hereof be governed
by and interpreted in accordance with the Laws of England.

               AMENDMENT No. 1 made as of this 1st day of August, 1997 (this
"AMENDMENT") to the AMENDED AND RESTATED SHIPBUILDING CONTRACT (the
"SHIPBUILDING CONTRACT") dated as of June 26, 1997 among Navigator Gas (IOM I-D)
Limited as assignee of Navigator Holdings PLC's rights, title and interest (the
"BUYER") and China Shipbuilding Trading Company, Limited and Jiangnan Shipyard
(collectively, as "SELLER") for construction of one (1) 22,000 Cubic Meters
Liquified Ethylene Gas Carrier (Hull No. 2248). Capitalized terms used and not
otherwise defined herein shall have the respective meanings set forth in the
SHIPBUILDING CONTRACT.

               WHEREAS, the BUYER and SELLER desire to amend certain terms and
schedules of the SHIPBUILDING CONTRACT to and in accordance with Section 7 of
Article XXI of the SHIPBUILDING CONTRACT for the purpose of correcting
provisions therein which have resulted from the increased cost of borrowing
incurred by the BUYER to finance the acquisition of the Vessel;

                           NOW, THEREFORE, in consideration of the foregoing,
BUYER and SELLER agree as follows:


               1. Section 7(a) of Article II of the SHIPBUILDING CONTRACT is
hereby deleted in its entirety and is hereby amended to read as follows:

               "(a) All payments made by the BUYER hereunder in United States
Dollars and prior to Delivery and BUYER's acceptance of the VESSEL shall be in
the nature of installments to the SELLER. In the event that, the VESSEL is
rejected by the BUYER, or this Contract is canceled or terminated by the BUYER,
all in accordance with the terms of this Contract, or if the SELLER should
default in Delivery of the VESSEL or is guilty of breach of this Contract
justifying a rescission thereof by the BUYER then, and in any such event, the
SELLER shall refund to the BUYER an amount equal to the sum of the following:

                                    (i) the amounts set forth in Schedule 2
                           hereto calculated as of the first day of the calendar
                           month in which the Date of Rejection occurs,

                                    (ii) an amount equal to the product of (x)
                           the difference between (1) the amount set forth on
                           Schedule 2 hereto calculated as of the first day of
                           the calendar month immediately succeeding the month
                           in which the Date of Rejection occurs and (2) the
                           amount set forth on Schedule 2 hereto as of the first
                           day of the month in which the Date of Rejection
                           occurs and (y) a fraction the numerator of which is
                           the numeric day of the month of the Date of Rejection
                           and the denominator of which is 30, and

                                    (iii) the amount set forth on Schedule 3
                           hereto calculated as of the calendar month in which
                           the Date of Rejection occurs.


<PAGE>

If the amount as calculated above is not paid on the Date of Rejection there
shall be added to such amount interest at the rate of eleven percent (11.0%) per
annum from and including the Date of Rejection to but not including the date
such amount is paid. Such refunds by the SELLER to the BUYER shall forthwith
discharge all obligations, duties, and liabilities of each of the parties hereto
to the other under this Contract. Any and all refunds made to the BUYER under
this Article II, Section 7 shall be made in United States Dollars. Throughout
this Contract, whenever interest is due on any amounts to be paid or refunded by
either party, said interest shall be calculated as simple interest, based on the
actual number of days divided by 360.

               For purposes of this Section 7(a) Date of Rejection means the
date on which written notice of rejection, cancellation or rescission is
delivered by BUYER to SELLER.

               All refunds made by the SELLER to the BUYER under this contract
shall be paid in United States Dollars by telegraphic transfer to the BUYER's
account or its assignee's account as set forth in a written notice to the SELLER
from such party."

               2. Section 1(a)(ii) of Article III of the SHIPBUILDING CONTRACT
is hereby deleted in its entirety and is hereby amended to read as follows:

                           "(ii) If the Delivery is not made on the Original
               Delivery Date (subject to a Permissible Delay as defined below),
               the SELLER shall pay the BUYER, as liquidated damages (not as
               penalty), the amount of $11,000 for each calendar day for the
               first ninety (90) calendar days of delay beyond the Extended
               Delivery Date (as hereinafter defined) and the amount of $14,500
               for each calendar day of delay thereafter up to and including the
               210th day from the Original Delivery Date ("Original Delay
               Period"). Liquidated damages calculated with respect to the
               Original Delay Period shall be recovered by the BUYER through a
               reduction in the Fifth Installment payable by the BUYER to the
               SELLER in an amount equal to such Liquidated Damages."

               3. Section 3(a) of Article XI of the SHIPBUILDING CONTRACT is
hereby deleted in its entirety and is hereby amended to read as follows:

               "(a) If the BUYER is in default of payment as to any installment
as provided in Paragraph 1 (a) and/or 1 (b) of this Article, the BUYER shall pay
interest on such installment at the rate of eleven percent (11.0%) per annum
until the date of the payment of the full amount, including all aforesaid
interest. In case the BUYER shall fail to take delivery of the VESSEL when
required to as provided in Section 1 (c) of this Article, the BUYER shall be
deemed in default of payment of the fifth installment and shall pay interest
thereon at the same rate as aforesaid from and including the day on which the
VESSEL is tendered for delivery by the SELLER, as provided in Article VII
Section 6 hereof."

               4. Schedule 2 of the SHIPBUILDING CONTRACT is hereby deleted in
its entirety and Schedule 2 attached hereto shall be attached as Schedule 2 to
the SHIPBUILDING CONTRACT.

deleted in its entirety and Schedule 1 to Exhibit A attached hereto shall be

               7. The parties hereto agree that the validity, enforcement and
interpretation of this AMENDMENT and of each Article and part hereof be governed
by and interpreted in accordance with the Laws of England.

               AMENDMENT No. 1 made as of this 1st day of August, 1997 (this
"AMENDMENT") to the AMENDED AND RESTATED SHIPBUILDING CONTRACT (the
"SHIPBUILDING CONTRACT") dated as of June 26, 1997 among Navigator Gas (IOM I-E)
Limited as assignee of Navigator Holdings PLC's rights, title and interest (the
"BUYER") and China Shipbuilding Trading Company, Limited and Jiangnan Shipyard
(collectively, as "SELLER") for construction of one (1) 22,000 Cubic Meters
Liquified Ethylene Gas Carrier (Hull No. 2249). Capitalized terms used and not
otherwise defined herein shall have the respective meanings set forth in the
SHIPBUILDING CONTRACT.

               WHEREAS, the BUYER and SELLER desire to amend certain terms and
schedules of the SHIPBUILDING CONTRACT to and in accordance with Section 7 of
Article XXI of the SHIPBUILDING CONTRACT for the purpose of correcting
provisions therein which have resulted from the increased cost of borrowing
incurred by the BUYER to finance the acquisition of the Vessel;

                           NOW, THEREFORE, in consideration of the foregoing,
BUYER and SELLER agree as follows:


               1. Section 7(a) of Article II of the SHIPBUILDING CONTRACT is
hereby deleted in its entirety and is hereby amended to read as follows:

               "(a) All payments made by the BUYER hereunder in United States
Dollars and prior to Delivery and BUYER's acceptance of the VESSEL shall be in
the nature of installments to the SELLER. In the event that, the VESSEL is
rejected by the BUYER, or this Contract is canceled or terminated by the BUYER,
all in accordance with the terms of this Contract, or if the SELLER should
default in Delivery of the VESSEL or is guilty of breach of this Contract
justifying a rescission thereof by the BUYER then, and in any such event, the
SELLER shall refund to the BUYER an amount equal to the sum of the following:

                                    (i) the amounts set forth in Schedule 2
                           hereto calculated as of the first day of the calendar
                           month in which the Date of Rejection occurs,

                                    (ii) an amount equal to the product of (x)
                           the difference between (1) the amount set forth on
                           Schedule 2 hereto calculated as of the first day of
                           the calendar month immediately succeeding the month
                           in which the Date of Rejection occurs and (2) the
                           amount set forth on Schedule 2 hereto as of the first
                           day of the month in which the Date of Rejection
                           occurs and (y) a fraction the numerator of which is
                           the numeric day of the month of the Date of Rejection
                           and the denominator of which is 30, and

                                    (iii) the amount set forth on Schedule 3
                           hereto calculated as of the calendar month in which
                           the Date of Rejection occurs.


<PAGE>

If the amount as calculated above is not paid on the Date of Rejection there
shall be added to such amount interest at the rate of eleven percent (11.0%) per
annum from and including the Date of Rejection to but not including the date
such amount is paid. Such refunds by the SELLER to the BUYER shall forthwith
discharge all obligations, duties, and liabilities of each of the parties hereto
to the other under this Contract. Any and all refunds made to the BUYER under
this Article II, Section 7 shall be made in United States Dollars. Throughout
this Contract, whenever interest is due on any amounts to be paid or refunded by
either party, said interest shall be calculated as simple interest, based on the
actual number of days divided by 360.

               For purposes of this Section 7(a) Date of Rejection means the
date on which written notice of rejection, cancellation or rescission is
delivered by BUYER to SELLER.

               All refunds made by the SELLER to the BUYER under this contract
shall be paid in United States Dollars by telegraphic transfer to the BUYER's
account or its assignee's account as set forth in a written notice to the SELLER
from such party."

               2. Section 1(a)(ii) of Article III of the SHIPBUILDING CONTRACT
is hereby deleted in its entirety and is hereby amended to read as follows:

                           "(ii) If the Delivery is not made on the Original
               Delivery Date (subject to a Permissible Delay as defined below),
               the SELLER shall pay the BUYER, as liquidated damages (not as
               penalty), the amount of $11,000 for each calendar day for the
               first ninety (90) calendar days of delay beyond the Extended
               Delivery Date (as hereinafter defined) and the amount of $14,500
               for each calendar day of delay thereafter up to and including the
               210th day from the Original Delivery Date ("Original Delay
               Period"). Liquidated damages calculated with respect to the
               Original Delay Period shall be recovered by the BUYER through a
               reduction in the Fifth Installment payable by the BUYER to the
               SELLER in an amount equal to such Liquidated Damages."

               3. Section 3(a) of Article XI of the SHIPBUILDING CONTRACT is
hereby deleted in its entirety and is hereby amended to read as follows:

               "(a) If the BUYER is in default of payment as to any installment
as provided in Paragraph 1 (a) and/or 1 (b) of this Article, the BUYER shall pay
interest on such installment at the rate of eleven percent (11.0%) per annum
until the date of the payment of the full amount, including all aforesaid
interest. In case the BUYER shall fail to take delivery of the VESSEL when
required to as provided in Section 1 (c) of this Article, the BUYER shall be
deemed in default of payment of the fifth installment and shall pay interest
thereon at the same rate as aforesaid from and including the day on which the
VESSEL is tendered for delivery by the SELLER, as provided in Article VII
Section 6 hereof."

               4. Schedule 2 of the SHIPBUILDING CONTRACT is hereby deleted in
its entirety and Schedule 2 attached hereto shall be attached as Schedule 2 to
the SHIPBUILDING CONTRACT.

ANNEX "D"

                              DRUG & ALCOHOL POLICY

                                    PREAMBLE

The abuse of drugs and alcohol and their effects are one of the most significant
social problems of our time. Appropriately they are receiving increasing
attention both in public and in legislation.

In response to this increased concern the _____________ (hereinafter referred to
as "Company") has prepared the following policy statement and attendant rules
that are to be adhered to by all personnel employed on vessels owned and/or
managed by the company.

It is our aim to enforce this policy as part of a vital contribution to safety
and health on board as well as to a safe and efficient operation at
installations used by the vessels.

POLICY
- ------

1.       No crewmember or master shall be intoxicated at any time.

2.       No crewmember or master shall navigate or assist in navigating a ship
         or operate its equipment or perform any scheduled duties while impaired
         by drugs or alcohol.

3.       The misuse of legitimate drugs or the use, possession, distribution or
         sale of illicit or unprescribed drugs on board ships is prohibited.

4.       Any crewmember using medicines which can cause or can contribute to
         unacceptable job performance or unusual job behavior shall report this
         to the master. The master is then to take action appropriate to the
         situation.

5.       Use of other substances which alone or in combination can cause or
         continue to unacceptable job performance or unusual job behavior is
         prohibited.

CONTROL
- -------

1.       The master shall be responsible for the control of the use of alcohol
         and prescribed drugs onboard.

2.       Under no circumstances are the master or crewmembers allowed to consume
         alcoholic beverages in such quantities that will hinder them from
         reacting efficiently in an emergency (see procedure 3.).


                                      - 6 -
<PAGE>

3.       Masters, officers and ratings shall observe a period of abstinence from
         alcohol prior to commencement of watch or duty. This is to ensure that
         they are not intoxicated when going on duty. The length of this period
         of abstinence depends on the amount of alcohol consumed beforehand. It
         must be taken into account that the human body is able to reduce an
         average of 0,15 0/00 alcohol per hour.

         A blood alcohol content of 0,15 0/00 is reached after consumption of
         about one unit according to the following table:

                                            Volume                     Units
Beer and Lagers                             250cc                       1
Extra Strength Beer and Lagers              250cc                       2.5
Spirit/Liquor                               30cc                        1
Table Wine                                  100cc                       1
Sherry or Fortified Wine                    60cc                        1

If the consumption of alcohol equals four units according to the above table the
period of abstinence must be at least four hours.

PROCEDURES
- ----------

1.       Any crewmember or master found misusing legitimate drugs or found in
         possession of or using, selling, distributing or smuggling illicit or
         unprescribed drugs shall be dismissed by the company.

2.       Any crewmember or master found impaired by alcohol or drugs while on
         duty shall immediately be relieved of his duties and replaced. The
         master and a relevant witness shall report such alcohol or drug abuse
         to the company in writing as soon as possible. A copy of such report
         will be put in before to the subject crewmember for signature.

3.       When the effect of intoxicants on a person's manner, disposition,
         speech, general appearance or behavior is apparent by observation the
         master is to arrange for an alcohol test with the testing device. A
         crewmember or master shall be considered impaired when having an
         alcohol content of 0,4 0/00 (40mg/100 ml blood) or greater.

4.       Every position of a master and officer shall be tested twice a year for
         alcohol and drug abuse. Such tests shall be unannounced and shall be
         taken during the person's duty. The person(s) to be tested and the
         date/time shall be designated by the Company.

5.       The Company will supply the necessary testing devices.


                                      - 7 -
<PAGE>

DISTRIBUTION
- ------------

All crewmembers and masters will be given a copy of this document and are to
sign the attached form. The form is to be kept by the Master and a copy is to be
sent to the Company's office. The master is responsible for ensuring that all
members of the crew are fully aware of and understand the Company's "Drug and
Alcohol Policy".

Company (hereinafter collectively called "Contractor"):

                                   WITNESSETH:

                  WHEREAS, each Owner (as assignee of Navigator Holdings PLC)
and Contractor entered into a Shipbuilding Contract for construction
(hereinafter called the "Shipbuilding Contract") as of the 4th day of February,
1997, covering the construction of a total of five (5) 22,000 cubic meters
liquified/ethylene gas carriers identified on Schedule 1 hereto (each a "Vessel"

                  WHEREAS, all defined terms contained herein shall have the
meaning set forth in the Shipbuilding Contract.

                  WHEREAS, Owner desires Supervisor, as agent for Owner, to act
as Owner's technical representative with respect to technical matters related to
the construction of the Vessel, including the guarantee after delivery of the
Vessel under the Shipbuilding Contract.

                  WHEREAS, Owner agrees to employ Supervisor with respect to the
technical matters above mentioned under the Shipbuilding Contract.

                  NOW, THEREFORE, in consideration of the mutual covenants
herein contained, it is mutually understood and agreed upon by and among the
parties hereto as follows:


1. (a) Owner hereby appoints Supervisor as authorized technical representative
to perform any and all of Owner's rights, duties, obligations and
responsibilities under the provisions of Articles IV, V, VI, IX of the
Shipbuilding Contract (hereinafter called "Articles") except those rights,
duties, obligations and responsibilities which are specifically otherwise agreed
upon in this Agreement. For purposes of this Agreement, the term Owner means
each Owner who is a signatory to this Agreement to the extent that such Owner's
Vessel is subject to this Agreement.

                  (b) Supervisor hereby accepts such appointment by Owner, and 
undertakes to perform in good faith for and on behalf of Owner any and all of
Owner's rights, duties,

obligations and responsibilities under the Articles, solely in its capacity as
agent for the Owners.

                  (c) Supervisor further undertakes to perform such appointment
with due care so as to protect the rights and interests of Owner under the
Shipbuilding Contract. Owner hereby acknowledges that Supervisor's performance
of this appointment and any liabilities associated with it or arising out of
such appointment shall terminate upon delivery of the Vessel to the Owner;
provided, however, to the extent any loss, claim or damage is not discovered by
Owner at the time of the delivery of the Vessel, Supervisor's liability
therefore shall continue.

                  (d) Contractor hereby acknowledges Owner's appointment of
Supervisor and agrees to direct all correspondence and communications under
Articles directly to Supervisor. Notwithstanding the above, prior to making any
changes to the specification which materially effect the terms and conditions of
the Shipbuilding Contract, Contractor shall advise the Owner.

                  2. Notwithstanding anything contained in the Shipbuilding 
Contract the following is agreed by the parties hereto:

                  (a) Owner shall have the right, at its request, to be informed
         of anything under this Agreement, to observe the Vessel during the
         construction and attend the trial runs of the Vessel as observer(s)
         whose comment, if any, shall always be made through Supervisor to
         Contractor. The approval and/or decisions given to Contractor by
         Supervisor shall be deemed as those of Owner and shall bind Owner.

                                                                               3

         any untrue statement of a material fact or omit to state any material
         fact necessary in order to make the statements therein, in the light
         of the circumstances under which they were made, not misleading. The
         preceding sentence does not apply to statements in or omissions from
         the Offering Document based upon written information furnished to the
         Issuers or the Guarantors by any Purchaser through Credit Suisse First
         Boston Corporation ("CSFBC") specifically for use therein, it being
         expressly understood and agreed that the only such information is that
         described as such in Section 7(b) hereto.

                  (b) Each of the Issuers and the Guarantors has been duly
         incorporated and is a validly existing corporation in good standing
         under the laws of the Isle of Man, with power and authority (corporate
         and other) to own its properties and conduct its business as described
         in the Offering Document; and each of the Issuers and the Guarantors is
         duly qualified to do business as a foreign corporation in good standing
         in all other jurisdictions in which its ownership or lease of property
         or the conduct of its business requires such qualification.

                  (c) All the issued and outstanding capital stock of Navigator
         and each of the Guarantors has been duly authorized and validly issued
         and is fully paid and nonassessable, and such capital stock is legally
         owned directly by Holdings (in the case of Navigator), except for one
         share of capital stock of Navigator that is beneficially owned by
         Holdings but legally owned by Mr. Edward Cain of 15-19 Athol Street,
         Douglas, Isle of Man, IM1 1LB, and by Navigator (in the case of the
         Guarantors), free from liens, encumbrances and defects, except those
         liens created by or pursuant to the Security Documents. Holdings has no
         direct or indirect subsidiaries other than Navigator and the
         Guarantors.

                  (d) Each of the Indentures (including the Guarantees), the
         Security Documents and the Intercompany Note has been duly authorized;
         the Offered Notes have been duly authorized; and when the Offered Notes
         are delivered and paid for pursuant to this Agreement on the Closing
         Date, each of the Indentures (including the Guarantees), the Security
         Documents and the Intercompany Note will have been duly executed and
         delivered and will conform to the description thereof contained in the
         Offering Document, such Offered Notes will have been duly executed,
         authenticated, issued and delivered and will conform to the description
         thereof contained in the Offering Document, and each of the Indentures
         (including the Guarantees), the Security Documents and the Intercompany
         Note, and such Offered Notes will constitute valid and legally binding
         obligations of the Issuers and the Guarantors, as the case may be,
         enforceable in accordance with their terms, subject to bankruptcy,
         insolvency, fraudulent transfer, reorganization, moratorium and similar
         laws of general applicability relating to or affecting creditors'
         rights and to general equity principles. On the date on which a Vessel
         is accepted by a Guarantor pursuant to a Building Contract (a "Delivery
         Date") and upon proper filing or recording in the appropriate registry
         and filing offices in the Republic of Liberia ("Liberia"), the Mortgage
         with respect to such Vessel will create a valid, perfected mortgage on
         such Vessel securing the payment of the Offered Notes in accordance
         with the terms thereof and, except as permitted by the Security
         Documents, on such Delivery Date, such Vessel will be free and clear of
         all Liens. On the Closing Date, upon the execution and delivery of the
         Intercreditor Agreement and the Issues of One Debenture and upon
         delivery to the Collateral Agent of certificates evidencing the Pledged
         Stock and the Intercompany Note, the Intercreditor Agreement and the
         Issues of One Debenture will create valid, first priority perfected
         security interests in the Closing Date Collateral securing the Offered
         Notes and the Guarantees in accordance with the terms thereof and the
         Closing Date Collateral will be free and clear of all liens, except
         those liens created by or pursuant to the Security Documents. The
         Closing Date Collateral and the Delivery

         and delivered by Holdings, such Warrants will conform to the
         description thereof contained in the Offering Document and the Warrant
         Agreement and the Warrants will constitute valid and legally binding

         amendment or supplementation without CSFBC's consent. If, at any time
         prior to the completion of the resale of the Offered Securities by the
         Purchasers, any event occurs as a result of which the Offering Document
         as then amended or supplemented would include an untrue statement of a
         material fact or omit to state any material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading, the Issuers promptly will notify
         CSFBC of such event and promptly will prepare, at its own expense, an
         amendment or supplement which will correct such statement or omission.
         Neither CSFBC's consent to, nor the Purchasers' delivery to offerees or
         investors of, any such amendment or supplement shall constitute a
         waiver of any of the conditions set forth in Section 6 hereto.

                  (b) The Issuers will furnish to CSFBC copies of any
         preliminary offering circular, the Offering Document and all amendments
         and supplements to such documents, in each case as soon as available
         and in such quantities as CSFBC requests, and the Issuers will furnish
         to CSFBC on the Closing Date three copies of the Offering Document
         signed by a duly authorized officer of each of the Issuers. At any time
         when either of the Issuers is not subject to Section 13 or 15(d) of the
         Exchange Act and is not exempt from reporting pursuant to Rule
         12g3-2(b) under the Exchange Act, the Issuers will promptly furnish or
         cause to be furnished to each of the Purchasers and, upon request of
         holders and prospective purchasers of the Offered Securities, to such
         holders and purchasers, copies of the information required to be
         delivered to holders and prospective purchasers of the Offered
         Securities pursuant to Rule 144A(d)(4) under the Securities Act (or any
         successor provision thereto) in order to permit compliance with Rule
         144A in connection with resales by such holders of the Offered
         Securities. The Issuers will pay the expenses of printing and
         distributing to the Purchasers all such documents.

                  (c) The Issuers will arrange for the qualification of the
         Offered Securities for sale and the determination of their eligibility
         for investment under the laws of such jurisdictions in the United
         States and Canada as CSFBC designates and will continue such
         qualifications in effect so long as required for the resale of the
         Offered Securities by the Purchasers, provided that neither of the
         Issuers nor any of the Guarantors will be required to qualify as a
         foreign corporation or to file a general consent to service of process
         in any such state.

                  (d) During the period of five years after the Closing Date,
         the Issuers will furnish to CSFBC and, upon request, to each of the
         other Purchasers, as soon as practicable after the end of each fiscal
         year, a copy of its annual report to stockholders for such year; and
         the Issuers will furnish to CSFBC and, upon request, to each of the
         other Purchasers (i) as soon as available, a copy of each report or
         financial statement furnished to or filed with the Commission or any

         Issuers is listed, and (ii) from time to time, such other information
         concerning the Issuers as CSFBC may reasonably request.

         Issuers will, upon request, furnish to CSFBC, each of the other
         Purchasers and any holder of Offered Securities a copy of the
         restrictions on transfer applicable to the Offered Securities.

                  (f) During the period of two years after the Closing Date, the
         Issuers will not, and will not permit any of its affiliates (as defined
         in Rule 144) to, resell any of the Offered Securities that have been
         reacquired by any of them.

                  (g) Neither of the Issuers nor any of the Guarantors will be
         or become, an open-end investment company, unit investment trust or
         face-amount certificate company that is or is required to be registered
         under Section 8 of the Investment Company Act, or is, or will be or
         become, a closed-end investment company required to be registered, but
         not registered, under the Investment Company Act.

                  (h) The Issuers and the Guarantors will pay all expenses
         (together with VAT where applicable) incidental to the performance of
         their obligations under this Agreement, the Registration Rights
         Agreement, the Indentures, the Security Documents, the Warrant
         Agreement and the Intercompany Note, including (i) the fees and
         expenses of the Trustees, the Collateral Agent, the Warrant Agent and
         their professional advisers; (ii) all expenses in connection with the
         execution, issue, authentication, packaging and initial delivery of the

         thereto; and (iv) the cost of any advertising approved by the Issuers
         in connection with the issue of the Offered Securities. The Issuers or
         the Guarantors will also pay or reimburse the Purchasers (to the extent
         incurred by them) for any expenses (including fees and disbursements of
         counsel) incurred in connection with qualification of the Offered
         Securities for sale under the laws of such jurisdictions in the United
         States and Canada as CSFBC designates and the printing of memoranda
         relating thereto, for any fees charged by investment rating agencies
         for the rating of the Offered Securities, for all travel expenses of
         the Purchasers', the Issuers' and the Guarantors' officers and
         employees and any other expenses of the Purchasers, the Issuers and the
         Guarantors in connection with attending or hosting meetings with
         prospective purchasers of the Offered Securities from the Purchasers
         and for expenses incurred in distributing preliminary offering
         circulars and the Offering Document (including any amendments and
         supplements thereto) to the Purchasers.

                  (i) In connection with the offering, until CSFBC shall have
         notified the Issuers and the other Purchasers of the completion of the
         resale of the Offered Securities, neither the Issuers nor any of their
         affiliates has or will, either alone or with one or more other persons,
         bid for or purchase for any account in which they or any of their

                                                                              12

         affiliates have a beneficial interest any Offered Securities or attempt
         to induce any person to purchase any Offered Securities; and neither
         the Issuers nor any of their affiliates will make bids or purchases
         for the purpose of creating actual, or apparent, active trading in, or
         of raising the price of, the Offered Securities.

                  (j) The Issuers and the Guarantors will indemnify and hold
         harmless the Purchasers against any documentary, stamp or similar
         issuance tax, including any interest and penalties, on the creation,
         issuance and sale of the Offered Securities and on the execution and
         delivery of this Agreement. All payments to be made by the Issuers or
         the Guarantors hereunder shall be made without withholding or deduction
         for or on account of any present or future taxes, duties or
         governmental charges whatsoever unless the Issuers or the Guarantors
         are compelled by law to deduct or withhold such taxes, duties or
         charges. In that event, the Issuers or the Guarantors shall pay such
         additional amounts as may be necessary in order that the net amounts
         received after such withholding or deduction shall equal the amounts
         that would have been received if no withholding or deduction had been
         made.

                  (k) The Issuers will cause each Offered Security to bear the
         legend set forth in the form of note attached as Exhibit 1 to the Rule
         144A/Regulation S Appendix to each Indenture or the form of warrant
         attached as Exhibit A to the Warrant Agreement, as the case may be,
         until such legend shall no longer be necessary or advisable because the
         Offered Securities are no longer subject to the restrictions on
         transfer described therein.

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

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

                  (a) The Purchasers shall have received from Coopers & Lybrand
         L.L.P. (i) a letter, dated the Closing Date, in an agreed form and (ii)
         a certificate, dated the Closing Date, certifying that after the
         application of the net proceeds of the offering as described in the
         Offering Document, the amounts held in the Pre-Funding Account will
         provide cash at such times and in such amounts as will be sufficient to
         pay, when due, each installment payment for the Purchase Price for each
         Vessel as well as all fees allocable to such Vessel prior to its
         Delivery Date, and the amounts held in the Capitalized Interest Account
         will provide cash at such times and in such amounts as will be
         sufficient to pay, when due, interest on the Allocated Principal Amount
         of the Offered Notes for each Vessel during the period prior to the
         Contractual Delivery Date of such Vessel.

                  (b) Subsequent to the execution and delivery of this
         Agreement, there shall not have occurred (i) a change in U.S. or
         international financial, political or economic conditions or currency
         exchange rates or exchange controls as would, in the judgment of CSFBC,
         be likely to prejudice materially the success of the proposed issue,
         sale or distribution of the Offered Securities, whether in the primary
         market or in respect of dealings in the secondary market, or (ii) (A)
         any change, or any development or event involving a prospective change,
         in the condition (financial or other), business, properties or results
         of operations of the Issuers or the Guarantors which, in the judgment
         of CSFBC, is material and adverse and makes it impractical or
         inadvisable to

         proceed with completion of the offering or the sale of and payment for
         the Offered Securities; (B) any downgrading in the rating of any debt
         securities of either of the Issuers or any of the Guarantors by any
         "nationally recognized statistical rating organization" (as defined
         for purposes of Rule 436(g) under the Securities Act), or any public
         announcement that any such organization has under surveillance or
         review its rating of any debt securities of either of the Issuers or
         any of the Guarantors (other than an announcement with positive
         implications of a possible upgrading, and no implication of a possible
         downgrading, of such rating); (C) any suspension or limitation of
         trading in securities generally on the New York Stock Exchange or The
         Nasdaq National Market, or any setting of minimum prices for trading
         on such exchange or such market, or any suspension of trading of any
         securities of either of the Issuers or any of their respective
         subsidiaries on any exchange or in the over-the-counter market; (D)
         any banking moratorium declared by U.S. Federal, New York or Isle of
         Man authorities; or (E) any outbreak or escalation of major
         hostilities in which the United States is involved, any declaration of
         war by Congress or any other substantial national or international
         calamity or emergency if, in the judgment of CSFBC, the effect of any
         such outbreak, escalation, declaration, calamity or emergency makes it
         impractical or inadvisable to proceed with completion of the offering
         or sale of and payment for the Offered Securities.

                  (c) The Purchasers shall have received an opinion, dated the
         Closing Date, of Thacher Proffitt & Wood, counsel for the Issuers and
         the Guarantors, substantially to the effect that:

                  insolvency, fraudulent transfer, reorganization, moratorium
                  and similar laws of general applicability relating to or

                  compliance with all provisions of the Indentures and other
                  relevant documents, the First Priority Notes will, and the

                  (d) The Purchasers shall have received an opinion, dated the
         Closing Date, of Cains, special Isle of Man counsel for the Issuers and
         the Guarantors, substantially to the effect that:

                           (i) each of the Issuers and the Guarantors has been
                  duly incorporated, is validly existing as a corporation in
                  good standing under the laws of the Isle of Man and has the
                  corporate power and authority to own its property and to
                  conduct its business as described in the Offering Document;

                           (ii) the authorized capital stock of Holdings

                  contained in the Offering Document, and all capital stock in
                  Holdings has been duly authorized, and validly issued, fully
                  paid and nonassessable to such persons and for such

                           (iii) all the issued shares of capital stock of the
                  Issuers and the Guarantors have been duly authorized, validly

                  knowledge, all the issued shares of Navigator and the
                  Guarantors are legally owned by Holdings or Navigator,
                  respectively, free and clear of any pledge, lien, security
                  interest, charge, claim, equity or encumbrance of any kind,
                  except for one share of Navigator that is beneficially owned
                  by Holdings but legally owned by Mr. Edward Cain of 15-19
                  Athol Street, Douglas, Isle of Man, IM1 1LB, and except for
                  the security interests created by or pursuant to the Security

                  of capital stock of Navigator or any of the Guarantors;

                           (iv) the Offered Securities have been duly
                  authorized, executed, issued and delivered by Navigator or

                  party thereto);

                           (vi) each of the Indentures, the Security Documents
                  to be executed and delivered on the Closing Date, the Warrant
                  Agreement, the Intercompany Note, the Letter of Credit
                  Reimbursement Agreement and the Collateral Agreements has been
                  duly authorized, executed and delivered by the Issuers and the

                  valid and legally binding obligations of the Issuer or the
                  Guarantor party thereto, enforceable against such Issuer or
                  such Guarantor in accordance with its terms, subject to
                  bankruptcy, insolvency, fraudulent transfer, reorganization,
                  moratorium or similar laws of general applicability affecting
                  creditors' rights and to general equity principles;

                  required under the laws of the Isle of Man in connection
                  with the Indentures or any Security Document or other fees
                  necessary to ensure the validity, effectiveness and priority
                  of any liens, charges and encumbrances created thereby have
                  been paid, other than in connection with the recording of the
                  Mortgages;

                           (viii) insofar as any matter of Isle of Man law is
                  addressed therein, the statements made in the Offering
                  Document, to the extent that they constitute matters of law or
                  legal conclusions, fairly present the information disclosed
                  therein;

                           (ix) no consent, approval, authorization, permission
                  or order of, or filing with, any court, regulatory body,
                  administrative agency or other governmental body of the Isle
                  of Man is required for the offering and sale of the Offered
                  Securities or for the execution, delivery and performance of
                  any of the Indentures, the Security Documents (including the
                  exercise by the Collateral Agent of the rights and remedies
                  granted to it under any of the Security Documents), the
                  Intercompany Note, the Warrant Agreement, the Letter of Credit
                  Reimbursement Agreement, the Collateral Agreements, this
                  Agreement or the Registration Rights Agreement by the
                  respective parties thereto, except for the filing of the
                  Security Documents with the Companies Registry in the Isle of
                  Man pursuant to Section 79 of the Companies Act, and except
                  for the permission of the Treasury of the Isle of Man pursuant
                  to Section 2(2)(d) of the Prevention of Fraud Act;

                           (x) the security interests created in the Closing
                  Date Collateral by each Security Document to be executed and
                  delivered on the Closing Date do not require any action to be
                  taken under or pursuant to the laws of the Isle of Man in
                  order to create or perfect such security interests or to
                  permit the Collateral Agent to enforce its rights under the
                  Security Document creating the same, other than (A) the
                  delivery by Holdings of the stock certificates of Navigator to
                  the Collateral Agent on the Closing Date, (B) the delivery by
                  Navigator of the stock certificates of the Guarantors to the
                  Collateral Agent on the Closing Date, (C) the delivery by each
                  Guarantor of an Intercompany Note to Navigator; and (D) the
                  filing of the Security Documents with the Companies Registry
                  in the Isle of Man pursuant to Section 79 of the Companies
                  Act;

                           (xi) each Issue of One Debenture under which the
                  related Guarantor creates, for the benefit of the Collateral
                  Agent as the secured party, a valid security interest in the
                  assets of such Guarantor and the proceeds thereof, which
                  security interest will, upon the filing of the Security
                  Documents with the Companies Registry in the Isle of Man
                  pursuant to Section 79 of the Companies Act, rank in priority
                  to other charges created by such Guarantor to such counsel's
                  knowledge after due inquiry, except for those interests which,
                  by operation of law, will take priority;

                           (xii) the security interests created by the Security
                  Documents (with the exception of floating charge elements of
                  the Issue of One Debenture and any other Security Document)
                  are specific and therefore, upon the filing of the Security
                  Documents with the Companies Registry in the Isle of Man
                  pursuant to Section 79 of the Companies Act, will rank in
                  priority to all other security interests in the Closing Date
                  Collateral and the Delivery Date Collateral that are not
                  created under the Security Documents, except for those
                  interests which, by operation of law, will take priority;

                                                                              18

                           (xiii) the Security Documents constitute, in respect
                  of floating charge elements thereof, a first priority
                  perfected floating charge (but not a fixed charge); recoveries
                  under the floating charge element may be subject to certain
                  preferential creditors;

                           (xiv) the choice of the law of the State of New York
                  to govern this Agreement, the Registration Rights Agreement,
                  the Indentures, the Security Documents to be executed and
                  delivered on the Closing Date, the Warrant Agreement, the
                  Intercompany Note and the Offered Securities constitutes a
                  valid choice of law insofar as the law of the Isle of Man is
                  concerned. The submission by the Issuers and the Guarantors to
                  the non-exclusive jurisdiction of any Federal or state court
                  in the Borough of Manhattan, The City of New York is a valid
                  submission insofar as the law of the Isle of Man is concerned;
                  in this regard we note that Cambridge Partners, L.L.C. has
                  accepted its appointment by the Issuers and the Guarantors as
                  their agent to accept service of process in the United States
                  of America under this Agreement, the Registration Rights
                  Agreement, the Indentures, the Security Documents, the Warrant
                  Agreement, the Intercompany Note and the Offered Securities;

                           (xv) in a suit on the merits brought before an Isle
                  of Man court, an Isle of Man court may, if so requested and at
                  its discretion, enforce an agreement between the parties as to
                  a judgment currency other than pounds sterling;

                           (xvi) any final and conclusive money judgment
                  (whether in pounds sterling or otherwise) obtained in a
                  properly constituted court of the United States will be
                  recognized and enforceable in any proceedings before the
                  courts of the Isle of Man without re-examination or
                  re-litigation on any matter which shall be the subject of that
                  judgment;

                           (xvii) none of the Issuers or the Guarantors nor any
                  of their respective properties has any immunity from
                  jurisdiction of any court or from any legal process under the
                  laws of the Isle of Man; and

                           (xviii) the execution, delivery and the performance
                  by the Issuers and the Guarantors of the Indentures, the
                  Security Documents, the Warrant Agreement, the Intercompany
                  Note, the Letter of Credit Reimbursement Agreement, the
                  Collateral Agreements, this Agreement and the Registration
                  Rights Agreement (to the extent a party thereto), and, in the
                  case of the Issuers, the issuance and sale of the Offered
                  Securities and the compliance with the terms and provisions
                  thereof, will not contravene their respective memorandum and
                  articles of association.

                  (e) The Purchasers shall have received from Cravath, Swaine &
         Moore, counsel for the Purchasers, such opinion, dated the Closing
         Date, with respect to the validity of the Offered Securities, the
         Offering Document, the exemption from registration for the offer and
         sale of the Offered Securities by the Issuers to the several Purchasers
         and the initial resales by the several Purchasers as contemplated
         hereby and other related matters as CSFBC may require, and the Issuers
         shall have furnished to such counsel such documents as they request for
         the purpose of enabling them to pass upon such matters. In rendering
         such opinion, Cravath, Swaine & Moore may rely as to all matters
         governed by United States maritime law or Liberian law upon the opinion
         of Thacher Proffitt & Wood referred to above, and as to the
         incorporation of the Issuers and the Guarantors and all other matters
         governed by Isle of Man law upon the opinion of Cains referred to
         above.

                  (f) The Purchasers shall have received a certificate, dated

         principal financial or accounting officer of each of the Issuers in

         Offered Securities and compliance with the terms and provisions thereof
         will not result in a breach or violation of any of the terms and
         provisions of, or constitute a default under, any agreement or
         instrument to which the Issuers or the Guarantors is a party or by
         which the Issuers or the Guarantors is bound or to which any of the
         properties of the Issuers or the Guarantors is subject, (iv) all shares
         of capital stock of Navigator and the Guarantors are legally owned,
         directly or indirectly, by Holdings (except for one share of capital
         stock of Navigator that is beneficially owned by Holdings but is
         legally owned by Mr. Edward Cain of 15-19 Athol Street, Douglas, Isle
         of Man, IM1 1LB) free and clear of any pledge, lien, security interest,

         (the "Builders Performance Bond") with respect to the Building
         Contracts, and (ii) Generale de Banque S.A. shall have executed and
         delivered an Irrevocable Performance Bond (together with the Builders
         Performance Bond, the "Performance Bonds"); and the Building Contract
         Guarantees and the Performance Bonds shall conform in the judgment of
         counsel to the Purchasers with the descriptions thereof contained in
         the Offering Document. The Purchasers shall have received conformed
         counterparts of, and all other documents and agreements entered into
         and received in connection with, the Building Contract Guarantees and
         the Performance Bonds.

                  (m) Concurrently with the issue and sale of the Offered
         Securities, the Guarantors shall have issued the Intercompany Note to
         Navigator, and the Intercompany Note shall have been duly authorized,
         executed and delivered by each Guarantor, shall constitute valid and
         legally binding obligations of such Guarantor and shall be enforceable
         in accordance with its terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and similar laws of
         general applicability relating to or affecting creditors' rights and to
         general equity principles; and the Purchasers shall have received
         conformed counterparts of the Intercompany Note.

                  (n) Concurrently with or prior to the issue and sale of the
         Offered Securities, each of the Triparty Agreement, the Management
         Agreement and the Assignment and Assumption Agreements shall have been
         duly authorized, executed and delivered by the Issuers and the
         Guarantors (to the extent a party thereto), shall constitute valid and
         legally binding obligations of the Issuers and the Guarantors (to the
         extent a party thereto) and shall conform, in the judgment of counsel
         to the Purchasers, to the description thereof contained in the Offering
         Document.

                  (o) The Purchasers shall have received on or prior to the
         Closing Date original signed letters from each of Standard & Poor's
         Ratings Group and Moody's Investors Services, Inc., in form and
         substance customary for ratings letters issued by such agencies and
         otherwise reasonably satisfactory to the Purchasers, in which each such
         rating agency confirms that it has issued ratings for the First
         Priority Notes of no less

                                                                              21

          that "BB-" and "B1", respectively, and for the Second Priority Notes
          of no less than "B" and "B3", respectively.

                  (p) The Purchasers shall have received a certificate, dated
         the Closing Date, of an officer of each of CSTC and Jiangnan in which
         such officers shall state that upon the payment of the initial
         installment of the Purchase Price of the Vessels on the Closing Date,
         there shall exist at and as of the Closing Date no condition that would
         constitute a default (or an event that with notice, a lapse of time, or
         both, would constitute a default) under any Building Contract.

                  (q) The Purchasers shall have received conformed counterparts
         of each of the Collateral Agreements, each if applicable as amended on
         or prior to the Closing Date, and each such document shall conform in
         the judgment of counsel to the Purchasers to the descriptions thereof
         contained in the Offering Document.

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

         7. INDEMNIFICATION AND CONTRIBUTION. (a) The Issuers and the Guarantors
will jointly and severally indemnify and hold harmless each Purchaser against
any losses, claims, damages or liabilities, joint or several, to which such
Purchaser may become subject, under the Securities Act or the Exchange Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any breach of any of the
representations and warranties of the Issuers and the Guarantors contained
herein or any untrue statement or alleged untrue statement of any material fact
contained in the Offering Document, or any amendment or supplement thereto, or
any related preliminary offering circular, or arise out of or are based upon the
omission or alleged omission to state therein a material fact necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading, and will reimburse each Purchaser for any legal
or other expenses reasonably incurred by such Purchaser in connection with
investigating or defending any such loss, claim, damage, liability or action as
such expenses are incurred; PROVIDED, HOWEVER, that neither the Issuers nor the
Guarantors will be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement in or omission or alleged omission from any of such
documents in reliance upon and in conformity with written information furnished
to the Issuers or the Guarantors by any Purchaser through CSFBC specifically for
use therein, it being understood and agreed that the only such information
consists of the information described as such in subsection (b) below.

         (b) Each Purchaser will severally and not jointly indemnify and hold
harmless the Issuers and the Guarantors against any losses, claims, damages or
liabilities to which the Issuers or the Guarantors may become subject, under the
Securities Act or the Exchange Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in the Offering Document, or any amendment or supplement thereto, or
any related preliminary offering circular, or arise out of or are based upon the
omission or the alleged omission to state therein a material fact necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in reliance upon and in conformity with written
information furnished to the Issuers or the Guarantors by such Purchaser through
CSFBC specifically for use therein, and will reimburse any legal or other
expenses reasonably incurred by the Issuers or the Guarantors in connection with
investigating or defending any such loss,

                                                                              22

claim, damage, liability or action as such expenses are incurred, it being
understood and agreed that the only such information furnished by any Purchaser
consists of the following information in the Offering Document furnished on
behalf of each Purchaser: the last paragraph at the bottom of the cover page
concerning the terms of the offering by the Purchasers, the legend concerning
over-allotments and stabilizing on the bottom paragraph of page seven and, under
the caption "Plan of Distribution", (i) the third sentence of the second
paragraph thereunder, (ii) the fourth paragraph thereunder and (iii) the third
sentence of the sixth paragraph thereunder; it being expressly agreed and
acknowledged by the Issuers and the Guarantors that the Purchasers have not
provided, and shall bear no responsibility or liability under this paragraph (b)
for, the information contained under the caption "Certain Financial Forecast
Information" in the Offering Document.

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

         (d) If the indemnification provided for in this Section is unavailable
or insufficient to hold harmless an indemnified party under subsection (a) or
(b) above, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in subsection (a) or (b) above (i) in such proportion as
is appropriate to reflect the relative benefits received by the Issuers or the
Guarantors on the one hand and the Purchasers on the other from the offering of
the Offered Securities or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Issuers or the Guarantors on the one hand and the
Purchasers on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities as well as any other
relevant equitable considerations. The relative benefits received by the Issuers
or the Guarantors on the one hand and the Purchasers on the other shall be
deemed to be in the same proportion as the total net proceeds from the offering
(before deducting expenses) received by the Issuers bear to the total discounts
and commissions received by the Purchasers from the Issuers under this
Agreement. The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Issuers, the Guarantors or the Purchasers and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such untrue statement or omission. The amount paid by an indemnified
party as a result of the losses, claims, damages or liabilities referred to in
the first sentence of this subsection (d) shall be deemed to include any legal
or other expenses reasonably incurred by such indemnified party in connection




<PAGE>


                                                                              23

with investigating or defending any action or claim which is the subject of this
subsection (d). Notwithstanding the provisions of this subsection (d), no
Purchaser shall be required to contribute any amount in excess of the amount by
which the total price at which the Offered Securities purchased by it were
resold exceeds the amount of any damages which such Purchaser has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. The Purchasers' obligations in this subsection (d) to
contribute are several in proportion to their respective purchase obligations
and not joint.

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

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

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

         10. NOTICES. All communications hereunder will be in writing and, if

them at 15-19 Athol Street, Douglas, Isle of Man, IM1 1LB, Attention: Mr. Edward
Cain; PROVIDED, HOWEVER, that any notice to a Purchaser pursuant to Section 7
will be mailed, delivered or telegraphed and confirmed to such Purchaser.

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

         12.  REPRESENTATION OF PURCHASERS.  CSFBC will act for the several 
Purchasers in connection with this offering and any action taken by CSFBC will
be binding upon all the Purchasers.

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

         14.  APPLICABLE LAW.  THIS AGREEMENT SHALL BE GOVERNED BY, AND 
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD
TO PRINCIPLES OF CONFLICTS OF LAWS.

         15. SUBMISSION TO JURISDICTION. The Issuers and the Guarantors hereby
submit to the non-exclusive jurisdiction of the Federal and state courts in the
Borough of Manhattan in The City of New York in any suit or proceeding arising
out of or relating to this Agreement or the transactions contemplated hereby.
The Issuers and the Guarantors irrevocably appoint Cambridge Partners, L.L.C.,
as their authorized agent in the Borough of Manhattan in The City of New York
upon which process may be served in any such suit or proceeding, and agree that
service of process upon such agent, and written notice of said service to the
Issuers or the Guarantors, as the case may be, by the person serving the same to
the address provided in Section 10, shall be deemed in every respect effective
service of process upon the Issuers or the Guarantors, as the case may be, in
any such suit or proceeding. The Issuers and the Guarantors further agree to
take any and all action as may be necessary to maintain such designation and
appointment of such agent in full force and effect for a period of seven years
from the date of this Agreement.

         16. JUDGMENT CURRENCY. The obligation of the Issuers and the Guarantors
in respect of any sum due to any Purchaser shall, notwithstanding any judgment
in a currency other than United States dollars, not be discharged until the
first business day, following receipt by such Purchaser of any sum adjudged to
be so due in such other currency, on which (and only to the extent that) such
Purchaser may in accordance with normal banking procedures purchase United
States dollars with such other currency; if the United States dollars so
purchased are less than the sum originally due to such Purchaser hereunder, the
Issuers and the Guarantors agree, as a separate obligation and notwithstanding
any such judgment, to indemnify, jointly and severally, such Purchaser against
such loss. If the United States dollars so purchased are greater than the sum
originally due to such Purchaser hereunder, such Purchaser agrees to pay to the
Issuers or the Guarantors, as the case may be, an amount equal to the excess of
the dollars so purchased over the sum originally due to such Purchaser
hereunder.

         If the foregoing is in accordance with the Purchasers' understanding of
our agreement, kindly sign and return to us one of the counterparts hereof,
whereupon it will become a binding agreement among the Issuers, the Guarantors
and the several Purchasers in accordance with its terms.

Dear Sirs:

              Navigator Gas Transport PLC, an Isle of Man public limited company
(the "Issuer"), proposes to issue and sell to Credit Suisse First Boston
Corporation ("CSFBC") and Cambridge Partners, L.L.C. ("Cambridge", and together

holders of the Notes (including the Initial Purchasers), the Exchange Securities
(as defined below) and the Private Exchange Securities (as defined below)
(collectively, the "Holders"), as follows:

              1. REGISTERED EXCHANGE OFFER. The Company shall, at its cost,
prepare and, not later than 45 days after (or if the 45th day is not a business
day, the first business day thereafter) the date of original issue of the Notes
(the "Issue Date"), file with the Securities and Exchange Commission (the
"Commission") a registration statement or statements (the "Exchange Offer
Registration Statement") on an appropriate form under the Securities Act of 1933
(the "Securities Act"), with respect to a proposed offer (each, a "Registered
Exchange Offer" and, collectively, the "Registered Exchange Offers") to the
Holders of the First Priority Notes and the Second Priority Notes, as the case
may be, who are not prohibited by any law or policy of the Commission from
participating in the relevant Registered Exchange Offer, to issue and deliver to
such Holders, in exchange for the Notes, a like aggregate principal amount of
debt securities of the Issuer (the "Exchange Securities") held by such Holders
issued under the relevant Indenture and identical in all material respects to
the First Priority Notes or the Second Priority Notes (except for the transfer
restrictions relating to such Notes), as the case may be, that would be
registered under the Securities Act. The Company shall use its best efforts to
cause the Exchange Offer Registration Statement to become effective under the
Securities Act within 150 days (or if the 150th day is not a business day, the
first business day thereafter) after the Issue Date of the Notes and shall keep
the Exchange Offer Registration Statement effective for not less than 30 days
(or longer, if required by applicable law) after the date notice of the
Registered Exchange Offers is mailed to the Holders (such period being called
the "Exchange Offer Registration Period").

              If the Company effects the Registered Exchange Offers, the Company
will be entitled to close the Registered Exchange Offers 30 days after the
commencement thereof provided that the Company has accepted all the Notes
theretofore validly tendered in accordance with the terms of the relevant
Registered Exchange Offer.

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

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

                                                                               3

to a Registered Exchange Offer and (ii) an Initial Purchaser that elects to sell
Exchange Securities acquired in exchange for Notes constituting any portion of
an unsold allotment is required to deliver a prospectus containing the
information required by Items 507 or 508 of Regulation S-K under the Securities
Act, as applicable, in connection with such sale.

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

              If, upon consummation of the Registered Exchange Offer, any
Initial Purchaser holds First Priority Notes or Second Priority Notes acquired
by it as part of its initial distribution, the Company, simultaneously with the
delivery of the Exchange Securities pursuant to the Registered Exchange Offer,
shall issue and deliver to such Initial Purchaser upon the written request of
such Initial Purchaser, in exchange (each, a "Private Exchange" and,
collectively, the "Private Exchanges") for the Notes held by such Initial
Purchaser, a like principal amount of debt securities of the Company issued
under the relevant Indenture and identical in all material respects (including
the existence of restrictions on transfer under the Securities Act and the
securities laws of the several states of the United States) to the First
Priority Notes or the Second Priority Notes (collectively, the "Private Exchange
Securities"), as the case may be. The Notes, the Exchange Securities and the
Private Exchange Securities are hereinafter collectively called the
"Securities".

              In connection with each Registered Exchange Offer, the Company
shall:

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

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

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

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

              (e)  otherwise comply with all applicable laws.

                                                                               4

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

              (x) accept for exchange all the Notes validly tendered and not
     withdrawn pursuant to the Registered Exchange Offer or the Private
     Exchange, as the case may be;

              (y)  deliver to the relevant Trustee for cancelation all the Notes
     so accepted for exchange; and

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

              Each Indenture will provide that the Exchange Securities delivered
in exchange for the relevant validly tendered Notes will not be subject to the
transfer restrictions set forth in such Indenture. Each Indenture will also
provide that all Securities outstanding under such Indenture will vote and
consent together on all matters as one class and that none of the Securities
subject to such Indenture will have the right to vote or consent as a separate
class on any matter.

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

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

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

                                                                               5

be stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading.

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

              (a) The Company shall, at its cost, as promptly as practicable
     (but in no event more than 30 days after so required or requested pursuant
     to this Section 2) file with the Commission and thereafter shall use its
     best efforts to cause to be declared effective a registration statement or
     statements (the "Shelf Registration Statement" and, together with the
     Exchange Offer Registration Statement, the "Registration Statements") on an
     appropriate form under the Securities Act relating to the offer and sale of
     the Transfer Restricted Securities (as defined in Section 6 hereof) by the
     Holders thereof from time to time in accordance with the methods of
     distribution set forth in the Shelf Registration Statement and Rule 415
     under the Securities Act (hereinafter, the "Shelf Registration"); PROVIDED,
     HOWEVER, that no Holder (other than an Initial Purchaser) shall be entitled
     to have the Securities held by it covered by such Shelf Registration
     Statement unless such Holder agrees in writing to be bound by all the
     provisions of this Agreement applicable to such Holder.

              (b) The Company shall use its best efforts to keep the Shelf
     Registration Statement continuously effective in order to permit the
     prospectus included therein to be lawfully delivered by the Holders of the
     relevant Securities, for a period of two years (or for such longer period
     if extended pursuant to Section 3(j) below) from the date of its
     effectiveness or such shorter period that will terminate when all the
     Securities covered by the Shelf Registration Statement (i) have been sold
     pursuant thereto or (ii) are eligible for sale under Rule 144(k) (or any
     successor provision) under the Securities Act. The Company shall be deemed
     not to have used its best efforts to keep the Shelf Registration Statement
     effective during the requisite period if it voluntarily takes any action
     that would result in Holders of Securities covered thereby not being able
     to offer and sell such Securities during that period, unless such action is
     required by applicable law.

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

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

              (a) The Company shall (i) furnish to each Initial Purchaser, prior
     to the filing thereof with the Commission, a copy of the Registration
     Statement and each amendment thereto and each supplement, if any, to the
     prospectus included therein and, in the event that an Initial Purchaser
     (with respect to any portion of an unsold allotment from the original
     offering) is participating in the Registered Exchange Offer or the Shelf
     Registration, shall use its best efforts to reflect in each such document,
     when so filed with the Commission, such comments as such Initial Purchaser
     reasonably may propose; (ii) include the information set forth in Annex A
     hereto on the cover, in Annex B hereto in the "Exchange Offer Procedures"
     section and the "Purpose of the Exchange Offer" section and in Annex C
     hereto in the "Plan of Distribution" section of the prospectus forming a
     part of the Exchange Offer Registration Statement and include the
     information set forth in Annex D hereto in the Letter of Transmittal
     delivered pursuant to the Registered Exchange Offer; (iii) if requested by
     an Initial Purchaser, include the information required by Items 507 or 508
     of Regulation S-K under the Securities Act, as applicable, in the
     prospectus forming a part of the Exchange Offer Registration Statement;
     (iv) include within the prospectus contained in the Exchange Offer
     Registration Statement a section entitled "Plan of Distribution,"
     reasonably acceptable to the Initial Purchasers, which shall contain a
     summary statement of the positions taken or policies made by the staff of
     the Commission with respect to the potential "underwriter" status of any
     broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under
     the Securities Exchange Act of 1934, as amended (the "Exchange Act")) of
     Exchange Securities received by such broker-dealer in such Registered
     Exchange Offer (a "Participating Broker-Dealer"), whether such positions or
     policies have been publicly disseminated by the staff of the Commission or
     such positions or policies, in the reasonable judgment of the Initial
     Purchasers based upon advice of counsel (which may be in-house counsel),
     represent the prevailing views of the staff of the Commission; and (v) in
     the case of a Shelf Registration Statement, include the names of the
     Holders who propose to sell Securities pursuant to the Shelf Registration
     Statement as selling securityholders.

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

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

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

                                                                               7

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

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

                      (v) of the happening of any event that requires the
              Company to make changes in the Registration Statement or the
              prospectus in order that the Registration Statement or the
              prospectus does not contain an untrue statement of a material fact
              nor omit to state a material fact required to be stated therein or
              necessary to make the statements therein (in the case of the
              prospectus, in light of the circumstances under which they were
              made) not misleading.

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

              (d) The Company shall furnish to each Holder of Securities
     included within the coverage of the Shelf Registration, without charge, at
     least one copy of the Shelf Registration Statement and any post-effective
     amendment thereto, including financial statements and schedules, and, if
     the Holder so requests in writing, all exhibits thereto (including those,
     if any, incorporated by reference).

              (e) The Company shall deliver to each Exchanging Dealer and each
     Initial Purchaser, and to any other Holder who so requests, without charge,
     at least one copy of the Exchange Offer Registration Statement and any
     post-effective amendment thereto, including financial statements and
     schedules, and, if any Initial Purchaser or any such Holder requests, all
     exhibits thereto (including those incorporated by reference, if any).

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

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

                                                                               8

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

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

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

              (j) Upon the occurrence of any event contemplated by paragraphs
     (ii) through (v) of Section 3(b) above during the period for which the
     Company is required to maintain an effective Registration Statement, the
     Company shall promptly prepare and file a post-effective amendment to the
     Registration Statement or a supplement to the related prospectus and any
     other required document so that, as thereafter delivered to Holders of the
     Securities or purchasers of Securities, the prospectus will not contain an
     untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein,
     in light of the circumstances under which they were made, not misleading.
     If the Company notifies the Initial Purchasers, the Holders of the
     Securities and any known Participating Broker-Dealer in accordance with
     paragraphs (ii) through (v) of Section 3(b) above to suspend the use of the
     prospectus until the requisite changes to the prospectus have been made,
     then the Initial Purchasers, the Holders of the Securities and any such
     Participating Broker-Dealers shall suspend use of such prospectus, and the
     period of effectiveness of the Shelf Registration Statement provided for in
     Section 2(b) above and the Exchange Offer Registration Statement provided
     for in Section 1 above, as the case may be, shall be extended by the number
     of days from and including the date of the giving of such notice to and
     including the date when the Initial Purchasers, the Holders of the
     Securities and any known Participating Broker-Dealer shall have received
     such amended or supplemented prospectus pursuant to this Section 3(j).

              (k) Not later than the effective date of the applicable
     Registration Statement, the Company will provide CUSIP numbers for the
     Notes, the Exchange Securities or the Private Exchange Securities, as the
     case may be, and provide the applicable Trustee with printed certificates
     for the Notes, the Exchange Securities or the Private Exchange Securities,
     as the case may be, in forms eligible for deposit with The Depository Trust
     Company.

              (l) The Company will comply with all rules and regulations of the
     Commission to the extent and so long as they are applicable to the

                                                                               9

     Shelf Registration and will make generally available to its security
     holders (or otherwise provide in accordance with Section 11(a) of the
     Securities Act) an earnings statement satisfying the provisions of Section
     11(a) of the Securities Act, no later than 45 days after the end of a
     12-month period (or 90 days, if such period is a fiscal year) beginning
     with the first month of Holdings' first fiscal quarter commencing after the
     effective date of the Registration Statement, which statement shall cover
     such 12-month period.

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

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

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

              (p) In the case of any Shelf Registration, the Company shall (i)
     make reasonably available for inspection by the Holders of the Securities,
     any underwriter participating in any disposition pursuant to the Shelf
     Registration Statement and any attorney, accountant or other agent retained
     by the Holders of the Securities or any such underwriter all relevant
     financial and other records, pertinent corporate documents and properties
     of the Company and (ii) cause the Company's officers, directors, employees,
     accountants and auditors to supply all relevant information reasonably
     requested by the Holders of the Securities or any such underwriter,
     attorney, accountant or agent in connection with the Shelf Registration
     Statement, in each case, as shall be reasonably necessary to enable such
     persons to conduct a reasonable investigation within the meaning of Section
     11 of the Securities Act; PROVIDED, HOWEVER, that the foregoing inspection
     and information gathering shall be coordinated on behalf of the Initial
     Purchasers by you and on behalf of the other parties, by one counsel
     designated by and on behalf of such other parties as described in Section 4
     hereof.

              (q) In the case of any Shelf Registration, the Company, if
     requested by any Holder of Securities covered thereby, shall cause (i) its
     counsel to deliver an opinion and updates thereof relating to the
     Securities in customary form addressed to such Holders and the managing
     underwriters, if any, thereof and dated, in the case of the initial
     opinion, the effective date of such Shelf Registration Statement (it being
     agreed that the matters to be covered by such opinion shall include the due
     incorporation and good standing of the Company and its subsidiaries; the
     qualification of the Company and its subsidiaries to transact business as
     foreign corporations; the due authorization, execution and delivery of the
     relevant agreement of the type referred to in Section 3(o) hereof; the

                                                                              10

     due authorization, execution, authentication and issuance, and the validity
     and enforceability, of the applicable Securities; the absence of material
     legal or governmental proceedings involving the Company and its
     subsidiaries; the absence of governmental approvals required to be obtained
     in connection with the Shelf Registration, the offering and sale of the
     applicable Securities, or any agreement of the type referred to in Section
     3(o) hereof and the compliance as to form of the Shelf Registration
     Statement and any documents incorporated by reference therein and of the
     Indentures with the requirements of the Securities Act and the Trust
     Indenture Act, respectively. Such opinion shall also state that no facts
     have come to such counsel's attention which lead it to believe that, as of
     the date of the opinion and as of the effective date of the Shelf
     Registration Statement or most recent post-effective amendment thereto, as
     the case may be, the Shelf Registration Statement and the prospectus
     included therein, as then amended or supplemented, and from any documents
     incorporated by reference therein, contain any untrue statement of a
     material fact or omit to state therein a material fact required to be
     stated therein or necessary to make the statements therein not misleading
     (in light of the circumstances existing at the time that such documents
     were filed with the Commission under the Exchange Act); (ii) its officers
     to execute and deliver all customary documents and certificates and updates
     thereof requested by any underwriters of the applicable Securities and
     (iii) its independent public accountants to provide to the selling Holders
     of the applicable Securities and any underwriter therefor a comfort letter
     in customary form and covering matters of the type customarily covered in
     comfort letters in connection with primary underwritten offerings, subject
     to receipt of appropriate documentation as contemplated, and only if
     permitted, by Statement of Auditing Standards No. 72.

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

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

              (t) The Company shall use its best efforts to (i) if the Notes of
     a series have been rated prior to the initial sale of such Notes, confirm
     that such ratings will apply to the Securities of such series covered by a
     Registration Statement, or (ii) if the Notes of a series were not
     previously rated, cause the Securities of such series covered by a
     Registration Statement to be rated with the appropriate rating agencies, if
     so requested by Holders of a majority in aggregate principal amount of
     Securities of such series covered by such Registration Statement, or by the
     managing underwriters, if any.

              (u) In the event that any broker-dealer registered under the
     Exchange Act shall underwrite any Securities or participate as a member of
     an underwriting syndicate or selling group or "assist in the distribution"
     (within the meaning of the Conduct Rules of the National Association of
     Securities Dealers, Inc. ("NASD")) thereof, whether as a Holder of such
     Securities or as an underwriter, a placement or sales agent or a broker or
     dealer in respect thereof, or otherwise, the Company shall assist such
     broker-dealer in complying with the requirements of such Conduct Rules,
     including by (i) if Rule 2720 thereto shall so require, engaging a
     "qualified independent underwriter" (as defined in Rule 2720) to
     participate in the preparation of the Registration Statement relating to
     such Securities, to exercise usual standards of due diligence in respect
     thereto and, if any portion of the offering contemplated by such
     Registration Statement is an underwritten offering or is made through a
     placement or sales agent, to recommend the yield of such Securities, (ii)
     indemnifying any such qualified independent underwriter to the extent of
     the indemnification of underwriters provided in Section 5 hereof and (iii)
     providing such information to such broker-dealer as may be required in
     order for such broker-dealer to comply with the requirements of the Conduct
     Rules of the NASD.

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

              4. REGISTRATION EXPENSES. The Company shall bear all fees and
expenses incurred in connection with the performance of its obligations under
Sections 1 through 3 hereof (including the reasonable fees and expenses, if any,
of Cravath, Swaine & Moore, counsel for the Initial Purchasers, incurred in
connection with the Registered Exchange Offers), whether or not a Registered
Exchange Offer or a Shelf Registration is filed or becomes effective, and, in
the event of a Shelf Registration, shall bear or reimburse the Holders of the
Securities covered thereby for the reasonable fees and disbursements of one firm
of counsel designated by the Holders of a majority in principal amount of the
Securities covered thereby to act as counsel for the Holders of the Securities
in connection therewith, PROVIDED that such Holders shall be responsible for any
and all underwriting discounts and commissions.

              5. INDEMNIFICATION. (a) The Issuer and Guarantors severally and
jointly agree to indemnify and hold harmless each Holder of the Securities, any
Participating Broker-Dealer and each person, if any, who controls such Holder or
such Participating Broker-Dealer within the meaning of the Securities Act or the
Exchange Act (each Holder, any Participating Broker-Dealer and such controlling
persons are referred to collectively as the "Indemnified Parties") from and
against any losses, claims, damages or liabilities, joint or several, or any
actions in respect thereof (including any losses, claims, damages, liabilities
or actions relating to purchases and sales of the Securities) to which a given
Indemnified Party may become subject under the Securities Act, the Exchange Act
or otherwise, insofar as such losses, claims, damages, liabilities or actions
arise out of or are based upon any untrue statement or alleged untrue statement
of a material fact contained in a Registration Statement or prospectus or in any
amendment or supplement thereto or in any preliminary prospectus relating to a
Shelf Registration, or arise out of, or are based upon, the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and shall reimburse, as
incurred, the Indemnified Parties for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action in respect thereof; PROVIDED, HOWEVER, that
(i) the Company shall not be liable in any such 



<PAGE>


                                                                              12

case to the extent that such loss, claim, damage or liability arises out of or
is based upon any untrue statement or alleged untrue statement or omission or
alleged omission made in a Registration Statement or prospectus or in any
amendment or supplement thereto or in any preliminary prospectus relating to a
Shelf Registration in reliance upon and in conformity with written information
pertaining to such Holder and furnished to the Company by or on behalf of such
Holder specifically for inclusion therein and (ii) with respect to any untrue
statement or omission or alleged untrue statement or omission made in any
preliminary prospectus relating to a Shelf Registration Statement, the indemnity
agreement contained in this subsection (a) shall not inure to the benefit of any
Holder or Participating Broker-Dealer from whom the person asserting any such
losses, claims, damages or liabilities purchased the Securities concerned, to
the extent that a prospectus relating to such Securities was required to be
delivered by such Holder or Participating Broker-Dealer under the Securities Act
in connection with such purchase and any such loss, claim, damage or liability
of such Holder or Participating Broker-Dealer results from the fact that there
was not sent or given to such person, at or prior to the written confirmation of
the sale of such Securities to such person, a copy of the final prospectus if
the Company had previously furnished copies thereof to such Holder or
Participating Broker-Dealer; PROVIDED FURTHER, HOWEVER, that this indemnity
agreement will be in addition to any liability which the Company may otherwise
have to such Indemnified Party. The Issuer and the Guarantor shall also
indemnify underwriters, their officers and directors and each person who
controls such underwriters within the meaning of the Securities Act or the
Exchange Act to the same extent as provided above with respect to the
indemnification of the Holders of the Securities if requested by such Holders.

              (b) Each Holder of the Securities, severally and not jointly, will
indemnify and hold harmless the Company and each person, if any, who controls
the Company within the meaning of the Securities Act or the Exchange Act from
and against any losses, claims, damages or liabilities or any actions in respect
thereof, to which the Company or any such controlling person may become subject
under the Securities Act, the Exchange Act or otherwise, insofar as such losses,
claims, damages, liabilities or actions arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained in a
Registration Statement or prospectus or in any amendment or supplement thereto
or in any preliminary prospectus relating to a Shelf Registration, or arise out
of or are based upon the omission or alleged omission to state therein a
material fact necessary to make the statements therein not misleading, but in
each case only to the extent that the untrue statement or omission or alleged
untrue statement or omission was made in reliance upon and in conformity with
written information pertaining to such Holder and furnished to the Company by or
on behalf of such Holder specifically for inclusion therein; and, subject to the
limitation set forth immediately preceding this clause, shall reimburse, as
incurred, the Company for any legal or other expenses reasonably incurred by the
Company or any such controlling person in connection with investigating or
defending any loss, claim, damage, liability or action in respect thereof. This
indemnity agreement will be in addition to any liability which such Holder may
otherwise have to the Company or any of its controlling persons.

              (c) Promptly after receipt by an indemnified party under this
Section 5 of notice of the commencement of any action or proceeding (including a
governmental investigation), such indemnified party will, if a claim in respect
thereof is to be made against the indemnifying party under this Section 5,
notify the indemnifying party of the commencement thereof; but the omission so
to notify the indemnifying party will not, in any event, relieve the
indemnifying party from any obligations to any indemnified party other than the
indemnification obligation provided in paragraph (a) or (b) above. In case any
such action is brought against any indemnified party, and it notifies the
indemnifying party of the 



<PAGE>


                                                                              13

commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it may wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party (who shall not, except with the consent
of the indemnified party, be counsel to the indemnifying party), and after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof the indemnifying party will not be liable to such
indemnified party under this Section 5 for any legal or other expenses, other
than reasonable costs of investigation, subsequently incurred by such
indemnified party in connection with the defense thereof. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened action in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party unless such settlement includes an
unconditional release of such indemnified party from all liability on any claims
that are the subject matter of such action.

              (d) If the indemnification provided for in this Section 5 is
unavailable or insufficient to hold harmless an indemnified party under
subsections (a) or (b) above, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to in
subsections (a) or (b) above (i) in such proportion as is appropriate to reflect
the relative benefits received by the indemnifying party or parties on the one
hand and the indemnified party on the other from the exchange of the relevant
Notes, pursuant to the relevant Registered Exchange Offer, or (ii) if the
allocation provided by the foregoing clause (i) is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of the
indemnifying party or parties on the one hand and the indemnified party on the
other in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities (or actions in respect thereof) as well
as any other relevant equitable considerations. The relative fault of the
parties shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
on the one hand or such Holder or such other indemnified party, as the case may
be, on the other, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The amount paid by an indemnified party as a result of the losses, claims,
damages or liabilities referred to in the first sentence of this subsection (d)
shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any action
or claim which is the subject of this subsection (d). Notwithstanding any other
provision of this Section 5(d), the Holders of the Securities shall not be
required to contribute any amount in excess of the amount by which the net
proceeds received by such Holders from the sale of the Securities pursuant to a
Registration Statement exceeds the amount of damages which such Holders have
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this subsection (d), each person,
if any, who controls such indemnified party within the meaning of the Securities
Act or the Exchange Act shall have the same rights to contribution




<PAGE>

                                                                              14

as such indemnified party and each person, if any, who controls the Company
within the meaning of the Securities Act or the Exchange Act shall have the same
rights to contribution as the Company.

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

              6. ADDITIONAL INTEREST UNDER CERTAIN CIRCUMSTANCES. (a) Additional
interest (the "Additional Interest") with respect to the Securities shall be
assessed as follows if any of the following events occur (each such event in
clauses (i) through (iii) below, a "Registration Default"):

              (i) If by September 22, 1997, neither the Exchange Offer
     Registration Statement nor the Shelf Registration Statement, each with
     respect to a series of Notes, has been filed with the Commission;

              (ii) If by February 3, 1998, the relevant Registered Exchange
     Offer is not consummated and, if required in lieu thereof, the Shelf
     Registration Statement is not declared effective by the Commission, each
     with respect to a series of Notes; or

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

Additional Interest shall accrue on the applicable Notes and any Private
Exchange Securities exchanged therefor at a rate of 0.50% per annum (the
"Additional Interest Rate") over and above the interest set forth in the title
of the Notes from and including the date on which any such Registration Default
shall occur to but excluding the date on which all such Registration Defaults as
to the relevant Securities have been cured.

              (b) A Registration Default referred to in Section 6(a)(iii)(B)
shall be deemed not to have occurred and be continuing in relation to a Shelf
Registration Statement or the related prospectus if (i) such purported
Registration Default has occurred solely as a result of (x) the filing of a
post-effective amendment to such Shelf Registration Statement to incorporate
annual audited financial information with respect to the Company where such
post-effective amendment is not yet effective and needs to be declared effective
to permit Holders to use the related prospectus or (y) the occurrence of other
material events, with respect to the Company that would need to be described in
such Shelf Registration Statement or the related prospectus and (ii) in the case
of clause (y), the Company is proceeding promptly and in good faith to amend or
supplement such Shelf Registration Statement and related prospectus to describe
such events; PROVIDED, HOWEVER, that if such purported Registration Default
occurs in any case for a continuous period in excess of 30 days, Additional
Interest shall be payable in accordance with the above paragraph from the day
such Registration Default occurs until such Registration Default is cured or
until the Company is no longer required



<PAGE>


                                                                              15

pursuant to this Agreement to keep such Registration Statement effective or such
Registration Statement or related prospectus usable.

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

              (d) "Transfer Restricted Securities" means each Security until (i)
the date on which such Security has been exchanged by a person other than a
broker-dealer for a freely transferrable Exchange Security in the Registered
Exchange Offer, (ii) following the exchange by a broker-dealer in the Registered
Exchange Offer of such Security for an Exchange Security, the date on which such
Exchange Security is sold to a purchaser who receives from such broker-dealer on
or prior to the date of such sale a copy of the prospectus contained in the
Exchange Offer Registration Statement, (iii) the date on which such Security 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
Security is distributed to the public pursuant to Rule 144 under the Securities
Act or is saleable pursuant to Rule 144(k) under the Securities Act.

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

              8. UNDERWRITTEN REGISTRATIONS. If any of the Transfer Restricted
Securities covered by any Shelf Registration are to be sold in an underwritten
offering, the investment banker or investment bankers and manager or managers
that will administer the offering ("Managing Underwriters") will be selected by
the Holders of a majority in aggregate principal amount of such Transfer
Restricted Securities to be included in such offering.

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

attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

              9.  MISCELLANEOUS.

              (a) AMENDMENTS AND WAIVERS. The provisions of this Agreement may
not be amended, modified or supplemented, and waivers or consents to departures
from the provisions hereof may not be given, except by the Company, the Initial
Purchasers (if affected by such amendment, modification, supplement, waiver or
consents) and the written consent of the Holders of a majority in principal
amount of the Securities (taken as a class) affected by such amendment,
modification, supplement, waivers or consents.

              (b) NOTICES. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, first-class mail,
facsimile transmission, or air courier which guarantees overnight delivery:

given by such Holder to the Company in accordance with the provisions of this
Section 9(b), which address initially is, with respect to each Holder, the

such Holder was first sent by the Initial Purchasers.

or otherwise) with respect to itself or its property, it hereby irrevocably
waives such immunity in respect of this Agreement, to the fullest extent
permitted by law.

              Each broker-dealer that receives Exchange Securities for its own
account pursuant to a Registered Exchange Offer must acknowledge that it will

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 Securities received in exchange for Notes
where such 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 Expiration Date (as defined herein), it
will make this Prospectus available to any broker-dealer for use in connection
with any such resale. See "Plan of Distribution."

              Each broker-dealer that receives Exchange Securities for its own
account in exchange for Notes, where such Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Securities. See Annex C, "Plan of
Distribution."

                              PLAN OF DISTRIBUTION

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

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

              For a period of 180 days after the Expiration Date the 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 to pay all expenses
incidental to the Exchange Offer (including the expenses of one counsel for the
Holders of the Securities) other than commissions or concessions of any brokers
or dealers and will indemnify the Holders of the Securities (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.

               10 1/2% First Priority Ship Mortgage Note Due 2007

                  1.  INTEREST

                  NAVIGATOR GAS TRANSPORT PLC, an Isle of Man public limited
company (such corporation, and its successors and assigns under the Indenture
hereinafter referred to, being herein called the "Company"), promises to pay
interest on the principal amount of this Security at the rate per annum shown
above; PROVIDED, HOWEVER, that if a Registration Default (as defined in the
Registration Rights Agreement) occurs, additional interest will accrue on this
Security at a rate of 0.50% per annum from and including the date on which any
such Registration Default shall occur to but excluding the date on which all
Registration Defaults have been cured. The Company will pay interest
semiannually on June 30 and December 31 of each year, commencing December 31,
1997. Interest on the Securities will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from August 7, 1997.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.


                  2.  METHOD OF PAYMENT

                  The Company will pay interest on the Securities (except
defaulted interest) to the Persons who are registered holders of Securities at
the close of business on the June 15 or December 15 next preceding the interest
payment date even if Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying
Agent to collect principal payments. The Company will pay principal and interest
in money of the United States that at the time of payment is legal tender for
payment of public and private debts. Payments in respect of the Securities
represented by a Global Security (including principal, premium and interest)
will be made by wire transfer of immediately available funds to the accounts
specified by The Depository Trust Company. The Company will make all payments in
respect of a certificated Security (including principal, premium and interest)
by mailing a check to the registered address of each Holder thereof; PROVIDED,
HOWEVER, that payments on a certificated Security will be made by wire transfer
to a U.S. dollar account maintained by the payee with a bank in the United
States if such Holder elects payment by wire transfer by giving written notice
to the Trustee or the Paying Agent to such effect designating such account no
later than 30 days immediately preceding the relevant due date for payment (or
such other date as the Trustee may accept in its discretion).


                  3.  PAYING AGENT AND REGISTRAR

                  Initially, United States Trust Company of New York, a bank and
trust company organized under the New York Banking Law ("Trustee"), will act as
Paying Agent and Registrar. The Company may appoint and change any Paying Agent,
Registrar or co-registrar without notice. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or
co-registrar.


                  4.  INDENTURE

                  The Company issued the Securities under an Indenture dated as
of August 1, 1997 ("Indenture"), among the Company, Holdings, the Guarantors and
the Trustee. The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as in effect on the date of the Indenture
(the "Act"). Terms defined in the Indenture and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
such terms, and Securityholders are referred to the Indenture and the Act for a
statement of those terms.

                  The Securities are general secured obligations of the Company
limited to $217,000,000 aggregate principal amount (subject to Section 2.06 of
the Indenture). The Indenture limits (i) the incurrence of additional debt by
the Company and the Owner, (ii) the payment of dividends on capital stock of the
Company and the purchase, redemption or retirement of capital stock or
subordinated indebtedness, (iii) investments, (iv) certain liens and
sale/leaseback transactions, (v) certain transactions with affiliates, (vi)
sales of assets, (vii) the issuance or sale of capital stock of subsidiaries and
(viii) certain consolidations, mergers and transfers of assets. The Indenture
also prohibits certain restrictions on distributions from the Owners.

                  5. OPTIONAL REDEMPTION

                  Except as set forth in the next two paragraphs, the Securities
may not be redeemed prior to June 30, 2002. On and after that date, the Company
may redeem the Securities in whole at any time or in part from time to time at
the following redemption prices (expressed in percentages of principal amount),
plus accrued interest to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on the related
Interest Payment Date):

Jurisdiction, or of any political subdivision or taxing authority thereof or
therein, or any change in the official administration, application or
interpretation of such laws, regulations or published tax rulings either
generally or in relation to any particular Securities, which change in official
administration, application or interpretation shall not have been available to
the public prior to such issue date and is notified to the Company or the
relevant Owners, as the case may be, on or after such issue date, it is

Company or the relevant Owners, as the case may be, would be required to pay,
any Additional Amounts pursuant to the Indenture or the terms of any Security in
respect of interest on the next succeeding Interest Payment Date (assuming, in
the case of the Owners, that a payment in respect of such interest were required
to be made by the relevant Owners under the Guarantees on such Interest Payment
Date), and that such obligation cannot be avoided by the Company or the relevant
Owners taking reasonable measures available to it, the Company or the relevant
Owners, as the case may be, may, at its option, redeem all (but not less than
all) the Securities in respect of which such Additional Amounts would be so
payable at any time, at a redemption price equal to 100% of the principal amount
thereof plus accrued interest to the date fixed for redemption; PROVIDED,
HOWEVER, that (a) no such notice of 

<PAGE>

redemption may be given earlier than 60 days prior to the earliest date on which
the Company or the relevant Owners, as the case may be, would be obligated, or
is substantially likely to be obligated, to pay such Additional Amounts were a
payment in respect of the Securities or the Guarantees, as the case may be, then
due, and (b) at the time any such redemption notice is given, such obligation,
or substantial likelihood, to pay such Additional Amounts must remain in effect.

30, 2000, the Company may redeem up to 35% of the aggregate principal amount of
Securities with the proceeds of one or more Public Equity Offerings (with the
cash proceeds thereof to the extent actually contributed to the Company)
following which there is a Public Market, at a redemption price (expressed as a
percentage of principal amount) of 110.5% plus accrued interest to the
redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the related interest payment date);

                  6.  MANDATORY REDEMPTION

                  In the event an Owner elects to terminate its Building
Contract because of a material breach thereof by the Builders (including a
failure to pay liquidated damages for any delay in the delivery of the related
Vessel), the Securities will be subject to mandatory redemption in part, on a
pro rata basis, in an aggregate principal amount equal to the Allocated
Principal Amount of the Securities for such Vessel and for each other Vessel
that has not been accepted by its related Owner as of the date of such
termination, at a redemption price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest to and including the date of
redemption (subject to the right of a Holder of record on the relevant record
date to receive interest due on the relevant Interest Payment Date), upon the

principal amount equal

<PAGE>


to the Allocated Principal Amount of the Securities for such Vessel, at a
redemption price equal to 101% of the principal amount thereof, plus accrued and
unpaid interest to the date of redemption (subject to the right of a Holder of
record on the relevant record date to receive interest due on the relevant
Interest Payment Date), upon the earlier to occur of (a) the receipt of the
Insurance Proceeds with respect to such Total Loss and (b) 60 days after such
Total Loss was deemed to have occurred.


                  7.  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 of Securities to be
redeemed at his registered address. Securities in denominations larger than
$1,000 may be redeemed in part but only in whole multiples of $1,000. If money

(or portions thereof) to be redeemed on the redemption date is deposited with
the Paying Agent on or before the redemption date, on and after such date
interest ceases to accrue on such Securities (or such portions thereof) called
for redemption.


                  8.  OFFERS TO PURCHASE

                  On each Available Cash Payment Date, the Company will be
required, to the extent of Available Cash on such Available Cash Payment Date,
to make an Available Cash Offer to each Holder of Securities to purchase such
Holder's Securities in whole or in part, at a price equal to 102% of the
principal amount thereof plus accrued and unpaid interest to the date of
purchase (subject to the right of Holders of record on the relevant record date
to receive interests due on the related Interest Payment Date) as provided in,

of Securities will have the right to cause the Company to purchase all or any
part of the Securities of such Holder at a purchase price equal to 101% of the
principal amount of the Securities to be purchased plus accrued interest to the
date of repurchase (subject to the right of Holders of record on the relevant
record date to receive interest due on the related Interest Payment Date) as
provided in, and subject to the terms of, the Indenture.

<PAGE>

                  9.  GUARANTEE

                  The payment by the Company of the principal of, and premium
and interest on, the Securities is fully and unconditionally guaranteed on a
joint and several senior basis by the Owners.


                  10.  SECURITY

                  The Securities will initially be secured by the Collateral
delivered on the Issue Date. Upon the occurrence of a Delivery Date with respect
to a Vessel the Securities will thereafter be secured by a first priority ship
mortgage on such Vessel and all other Collateral delivered on the Delivery Date
of such Vessel. The Securities will also have the benefit of the Letter of
Credit.


                  11.  DENOMINATIONS; TRANSFER; EXCHANGE

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


                  12.  PERSONS DEEMED OWNERS

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


                  13.  UNCLAIMED MONEY

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

<PAGE>

                  14.  DISCHARGE AND DEFEASANCE

                  Subject to certain conditions, the Company at any time may
terminate some or all of its and the Guarantors' obligations under the
Securities, the Security Agreements and the Indenture if the Company deposits
with the Trustee money or U.S. Government Obligations for the payment of
principal and interest on the Securities to redemption or maturity, as the case
may be.


                  15.  AMENDMENT, WAIVER

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount of the Securities and (ii)
any default or noncompliance with any provision may be waived with the written
consent of the Holders of a majority in principal amount of the Securities.
Subject to certain exceptions set forth in the Indenture, without the consent of
any Securityholder, the Company, the Guarantors and the Trustee may amend the
Indenture, the Security Agreements or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 5 of the Indenture,
or to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add additional guarantees with respect to the
Securities or to provide additional security for the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company or
the Guarantors, or to comply with any request of the SEC in connection with
qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Securityholder.


                  16.  DEFAULTS AND REMEDIES

                  Under the Indenture, Events of Default include (i) default for
30 days in payment of interest on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon redemption pursuant to paragraph 5
or 6 of the Securities, upon required purchase, upon acceleration or otherwise,
or failure by the Company or the Guarantors to redeem or purchase Securities
when required; (iii) failure by the Company to comply with other agreements in
the Indenture or the Securities, in certain cases subject to notice and lapse of
time; (iv) certain accelerations (including failure to pay within any grace
period after final maturity) of other Indebtedness of Holdings, the

<PAGE>

Company or the Owners if the amount accelerated (or so unpaid) exceeds $5.0
million; (v) certain events of bank- ruptcy or insolvency with respect to
Holdings, the Company or the Owners; (vi) certain judgments or decrees for the
payment of money in excess of $5.0 million, (vii) certain events or defaults
with respect to the Guarantees or the Security Agreements and (ix) the failure
by the Designated Owners to hold certain prescribed percentages of Voting Stock
and Capital Stock of Holdings. If an Event of Default occurs and is continuing,
the Trustee or the Holders of at least 25% in principal amount of the Securities
may declare all the Securities to be due and payable immediately. Certain events
of bankruptcy or insolvency are Events of Default which will result in the
Securities being due and payable immediately upon the occurrence of such Events
of Default.

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


                  17.  TRUSTEE DEALINGS WITH THE COMPANY

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


                  18.  NO RECOURSE AGAINST OTHERS

                  A director, officer, employee or stockholder, as such, of the
Company, Holdings, the Owners or the Trustee shall not have any liability for
any obligations of the Company, Holdings or the Owners under the Securities or
the Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation. By accepting a Security, each Securityholder
waives and releases all such

<PAGE>

liability. The waiver and release are part of the consideration for the issue of
the Securities.


                  19.  AUTHENTICATION

                  This Security shall not be valid until an authorized signatory
of the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to

               10 1/2% First Priority Ship Mortgage Note Due 2007

                  1.  INTEREST

                  NAVIGATOR GAS TRANSPORT PLC, an Isle of Man public limited
company (such corporation, and its successors and assigns under the Indenture
hereinafter referred to, being herein called the "Company"), promises to pay
interest on the principal amount of this Security at the rate per annum shown
above; PROVIDED, HOWEVER, that if a Registration Default (as defined in the
Registration Rights Agreement) occurs, additional interest will accrue on this
Security at a rate of 0.50% per annum from and including the date on which any
such Registration Default shall occur to but excluding the date on which all
Registration Defaults have been cured. The Company will pay interest
semiannually on June 30 and December 31 of each year, commencing December 31,
1997. Interest on the Securities will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from August 7, 1997.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.


                  2.  METHOD OF PAYMENT

                  The Company will pay interest on the Securities (except
defaulted interest) to the Persons who are registered holders of Securities at
the close of business on the June 15 or December 15 next preceding the interest
payment date even if Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying
Agent to collect principal payments. The Company will pay principal and interest
in money of the United States that at the time of payment is legal tender for
payment of public and private debts. Payments in respect of the Securities
represented by a Global Security (including principal, premium and interest)
will be made by wire transfer of immediately available funds to the accounts
specified by The Depository Trust Company. The Company will make all payments in
respect of a certificated Security (including principal, premium and interest)
by mailing a check to the registered address of each Holder thereof; PROVIDED,
HOWEVER, that payments on a certificated Security will be made by wire transfer
to a U.S. dollar account maintained by the payee with a bank in the United
States if such Holder elects payment by wire transfer by giving written notice
to the Trustee or the Paying Agent to such effect designating

<PAGE>

such account no later than 30 days immediately preceding the relevant due date
for payment (or such other date as the Trustee may accept in its discretion).

                  3.  PAYING AGENT AND REGISTRAR

                  Initially, United States Trust Company of New York, a bank and
trust company organized under the New York Banking Law ("Trustee"), will act as
Paying Agent and Registrar. The Company may appoint and change any Paying Agent,
Registrar or co-registrar without notice. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or
co-registrar.

                  4.  INDENTURE

                  The Company issued the Securities under an Indenture dated as
of August 1, 1997 ("Indenture"), among the Company, Holdings, the Guarantors and
the Trustee. The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as in effect on the date of the Indenture
(the "Act"). Terms defined in the Indenture and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
such terms, and Securityholders are referred to the Indenture and the Act for a
statement of those terms.

                  The Securities are general secured obligations of the Company
limited to $217,000,000 aggregate principal amount (subject to Section 2.06 of
the Indenture). The Indenture limits (i) the incurrence of additional debt by
the Company and the Owner, (ii) the payment of dividends on capital stock of the
Company and the purchase, redemption or retirement of capital stock or
subordinated indebtedness, (iii) investments, (iv) certain liens and
sale/leaseback transactions, (v) certain transactions with affiliates, (vi)
sales of assets, (vii) the issuance or sale of capital stock of subsidiaries and
(viii) certain consolidations, mergers and transfers of assets. The Indenture
also prohibits certain restrictions on distributions from the Owners.

Jurisdiction, or of any political subdivision or taxing authority thereof or
therein, or any change in the official administration, application or
interpretation of such laws, regulations or published tax rulings either
generally or in relation to any particular Securities, which change in official
administration, application or interpretation shall not have been available to
the public prior to such issue date and is notified to the Company or the
relevant Owners, as the case may be, on or after such issue date, it is
determined by the Company or the relevant Owners, as the case may be, that the
Company or the relevant Owners, as the case may be, would be required to pay,
any Additional Amounts pursuant to the Indenture or the terms of any Security in
respect of interest on the next succeeding Interest Payment Date (assuming, in
the case of the Owners, that a payment in respect of such interest were required
to be made by the relevant Owners under the Guarantees on such Interest Payment
Date), and that such obligation cannot be avoided by the Company or the relevant
Owners taking reasonable measures available to it, the Company or the relevant
Owners, as the case may be, may, at its option, redeem all (but not less than
all) the Securities in respect of which such Additional Amounts would be so
payable at any time, at a redemption price equal to 100% of the principal amount
thereof plus accrued interest to the date fixed for redemption; PROVIDED,
HOWEVER, that (a) no such notice of 



<PAGE>

redemption may be given earlier than 60 days prior to the earliest date on which
the Company or the relevant Owners, as the case may be, would be obligated, or
is substantially likely to be obligated, to pay such Additional Amounts were a
payment in respect of the Securities or the Guarantees, as the case may be, then
due, and (b) at the time any such redemption notice is given, such obligation,
or substantial likelihood, to pay such Additional Amounts must remain in effect.

                  In addition, at any time and from time to time prior to June
30, 2000, the Company may redeem up to 35% of the aggregate principal amount of
Securities with the proceeds of one or more Public Equity Offerings (with the
cash proceeds thereof to the extent actually contributed to the Company)
following which there is a Public Market, at a redemption price (expressed as a
percentage of principal amount) of 110.5% plus accrued interest to the
redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the related interest payment date);
PROVIDED, HOWEVER, that at least $100 million aggregate principal amount of the
Securities and $45 million aggregate principal amount of the Second Priority
Notes must remain outstanding after each such redemption.


                  6.  MANDATORY REDEMPTION

                  In the event an Owner elects to terminate its Building
Contract because of a material breach thereof by the Builders (including a
failure to pay liquidated damages for any delay in the delivery of the related
Vessel), the Securities will be subject to mandatory redemption in part, on a
pro rata basis, in an aggregate principal amount equal to the Allocated
Principal Amount of the Securities for such Vessel and for each other Vessel
that has not been accepted by its related Owner as of the date of such
termination, at a redemption price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest to and including the date of
redemption (subject to the right of a Holder of record on the relevant record
date to receive interest due on the relevant Interest Payment Date), upon the

related Building Contract(s) and (b) 60 days after the termination of such
Building Contract(s) by the related Owner(s).

subject to mandatory redemption in part, on a pro rata basis, in an aggregate
principal amount equal 

<PAGE>


to the Allocated Principal Amount of the Securities for such Vessel, at a
redemption price equal to 101% of the principal amount thereof, plus accrued and
unpaid interest to the date of redemption (subject to the right of a Holder of
record on the relevant record date to receive interest due on the relevant
Interest Payment Date), upon the earlier to occur of (a) the receipt of the
Insurance Proceeds with respect to such Total Loss and (b) 60 days after such
Total Loss was deemed to have occurred.


                  7.  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 of Securities to be
redeemed at his registered address. Securities in denominations larger than
$1,000 may be redeemed in part but only in whole multiples of $1,000. If money
sufficient to pay the redemption price of and accrued interest on all Securities
(or portions thereof) to be redeemed on the redemption date is deposited with
the Paying Agent on or before the redemption date, on and after such date
interest ceases to accrue on such Securities (or such portions thereof) called

                  8.  OFFERS TO PURCHASE

                  On each Available Cash Payment Date, the Company will be
required, to the extent of Available Cash on such Available Cash Payment Date,
to make an Available Cash Offer to each Holder of Securities to purchase such
Holder's Securities in whole or in part, at a price equal to 102% of the
principal amount thereof plus accrued and unpaid interest to the date of

                  9.  GUARANTEE

                  The payment by the Company of the principal of, and premium
and interest on, the Securities is fully and unconditionally guaranteed on a
joint and several senior basis by the Owners.


                  10.  SECURITY

                  The Securities will initially be secured by the Collateral
delivered on the Issue Date. Upon the occurrence of a Delivery Date with respect
to a Vessel the Securities will thereafter be secured by a first priority ship
mortgage on such Vessel and all other Collateral delivered on the Delivery Date
of such Vessel. The Securities will also have the benefit of the Letter of
Credit.


                  11.  DENOMINATIONS; TRANSFER; EXCHANGE

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


                  12.  PERSONS DEEMED OWNERS

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


                  13.  UNCLAIMED MONEY

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

<PAGE>

                  14.  DISCHARGE AND DEFEASANCE

                  Subject to certain conditions, the Company at any time may
terminate some or all of its and the Guarantors' obligations under the
Securities, the Security Agreements and the Indenture if the Company deposits
with the Trustee money or U.S. Government Obligations for the payment of
principal and interest on the Securities to redemption or maturity, as the case
may be.


                  15.  AMENDMENT, WAIVER

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount of the Securities and (ii)
any default or noncompliance with any provision may be waived with the written
consent of the Holders of a majority in principal amount of the Securities.
Subject to certain exceptions set forth in the Indenture, without the consent of
any Securityholder, the Company, the Guarantors and the Trustee may amend the
Indenture, the Security Agreements or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 5 of the Indenture,
or to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add additional guarantees with respect to the
Securities or to provide additional security for the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company or
the Guarantors, or to comply with any request of the SEC in connection with
qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Securityholder.


                  16.  DEFAULTS AND REMEDIES

                  Under the Indenture, Events of Default include (i) default for
30 days in payment of interest on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon redemption pursuant to paragraph 5
or 6 of the Securities, upon required purchase, upon acceleration or otherwise,
or failure by the Company or the Guarantors to redeem or purchase Securities
when required; (iii) failure by the Company to comply with other agreements in
the Indenture or the Securities, in certain cases subject to notice and lapse of
time; (iv) certain accelerations (including failure to pay within any grace
period after final maturity) of other Indebtedness of Holdings, the 

<PAGE>

Company or the Owners if the amount accelerated (or so unpaid) exceeds $5.0
million; (v) certain events of bank- ruptcy or insolvency with respect to
Holdings, the Company or the Owners; (vi) certain judgments or decrees for the
payment of money in excess of $5.0 million, (vii) certain events or defaults
with respect to the Guarantees or the Security Agreements and (ix) the failure
by the Designated Owners to hold certain prescribed percentages of Voting Stock
and Capital Stock of Holdings. If an Event of Default occurs and is continuing,
the Trustee or the Holders of at least 25% in principal amount of the Securities
may declare all the Securities to be due and payable immediately. Certain events
of bankruptcy or insolvency are Events of Default which will result in the
Securities being due and payable immediately upon the occurrence of such Events
of Default.

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


                  17.  TRUSTEE DEALINGS WITH THE COMPANY

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


                  18.  NO RECOURSE AGAINST OTHERS

                  A director, officer, employee or stockholder, as such, of the
Company, Holdings, the Owners or the Trustee shall not have any liability for
any obligations of the Company, Holdings or the Owners under the Securities or
the Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation. By accepting a Security, each Securityholder
waives and releases all such 

<PAGE>

liability. The waiver and release are part of the consideration for the
issue of the Securities.


                  19.  AUTHENTICATION

                  This Security shall not be valid until an authorized signatory
of the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.


                  20.  ABBREVIATIONS

                  Customary abbreviations may be used in the name of a
Securityholder or an assignee, such as TEN COM (=tenants in common), TEN ENT

and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to
Minors Act).

AGREEMENT

                  Each Holder of a Security, by acceptance hereof, acknowledges

                  THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO

               10 1/2% First Priority Ship Mortgage Note Due 2007

                  1.  INTEREST

                  NAVIGATOR GAS TRANSPORT PLC, an Isle of Man public limited
company (such corporation, and its successors and assigns under the Indenture
hereinafter referred to, being herein called the "Company"), promises to pay
interest on the principal amount of this Security at the rate per annum shown
above; PROVIDED, HOWEVER, that if a Registration Default (as defined in the
Registration Rights Agreement) occurs, additional interest will accrue on this
Security at a rate of 0.50% per annum from and including the date on which any
such Registration Default shall occur to but excluding the date on which all
Registration Defaults have been cured. The Company will pay interest
semiannually on June 30 and December 31 of each year, commencing December 31,
1997. Interest on the Securities will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from August 7, 1997.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

                  2.  METHOD OF PAYMENT

                  The Company will pay interest on the Securities (except
defaulted interest) to the Persons who are registered holders of Securities at
the close of business on the June 15 or December 15 next preceding the interest
payment date even if Securities are canceled after the record date and on or
before the interest payment date. Holders must surrender Securities to a Paying
Agent to collect principal payments. The Company will pay principal and interest
in money of the United States that at the time of payment is legal tender for
payment of public and private debts. Payments in respect of the Securities
represented by a Global Security (including principal, premium and interest)
will be made by wire transfer of immediately available funds to the accounts
specified by The Depository Trust Company. The Company will make all payments in
respect of a certificated Security (including principal, premium and interest)
by mailing a check to the registered address of each Holder thereof; PROVIDED,
HOWEVER, that payments on a certificated Security will be made by wire transfer
to a U.S. dollar account maintained by the payee with a bank in the United
States if such Holder elects payment by wire transfer by giving written notice
to the Trustee or the Paying Agent to such

<PAGE>


effect designating such account no later than 30 days immediately preceding the
relevant due date for payment (or such other date as the Trustee may accept in
its discretion).


                  3.  PAYING AGENT AND REGISTRAR

                  Initially, United States Trust Company of New York, a bank and
trust company organized under the New York Banking Law ("Trustee"), will act as
Paying Agent and Registrar. The Company may appoint and change any Paying Agent,
Registrar or co-registrar without notice. The Company or any of its domestically
incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or
co-registrar.


                  4.  INDENTURE

                  The Company issued the Securities under an Indenture dated as
of August 1, 1997 ("Indenture"), among the Company, Holdings, the Guarantors and
the Trustee. The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as in effect on the date of the Indenture
(the "Act"). Terms defined in the Indenture and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
such terms, and Securityholders are referred to the Indenture and the Act for a
statement of those terms.

                  The Securities are general secured obligations of the Company
limited to $217,000,000 aggregate principal amount (subject to Section 2.06 of
the Indenture). The Indenture limits (i) the incurrence of additional debt by
the Company and the Owner, (ii) the payment of dividends on capital stock of the
Company and the purchase, redemption or retirement of capital stock or
subordinated indebtedness, (iii) investments, (iv) certain liens and
sale/leaseback transactions, (v) certain transactions with affiliates, (vi)

also prohibits certain restrictions on distributions from the Owners.

may not be redeemed prior to June 30, 2002. On and after that date, the Company
may redeem the Securities in whole at any time or in part from time to time at

                  If, as a result of any change in or any amendment to the laws,
regulations or published tax rulings of the Isle of Man or any Successor
Jurisdiction, or of any political subdivision or taxing authority thereof or
therein, or any change in the official administration, application or
interpretation of such laws, regulations or published tax rulings either
generally or in relation to any particular Securities, which change in official
administration, application or interpretation shall not have been available to
the public prior to such issue date and is notified to the Company or the
relevant Owners, as the case may be, on or after such issue date, it is
determined by the Company or the relevant Owners, as the case may be, that the
Company or the relevant Owners, as the case may be, would be required to pay,
any Additional Amounts pursuant to the Indenture or the terms of any Security in
respect of interest on the next succeeding Interest Payment Date (assuming, in
the case of the Owners, that a payment in respect of such interest were required
to be made by the relevant Owners under the Guarantees on such Interest Payment
Date), and that such obligation cannot be avoided by the Company or the relevant
Owners taking reasonable measures available to it, the Company or the relevant
Owners, as the case may be, may, at its option, redeem all (but not less than
all) the Securities in respect of which such Additional Amounts would be so
payable at any time, at a redemption price equal to 100% of the principal amount
thereof plus accrued interest to the date fixed for redemption; PROVIDED,
HOWEVER, that (a) no such notice of 

<PAGE>


redemption may be given earlier than 60 days prior to the earliest date on which
the Company or the relevant Owners, as the case may be, would be obligated, or
is substantially likely to be obligated, to pay such Additional Amounts were a
payment in respect of the Securities or the Guarantees, as the case may be, then
due, and (b) at the time any such redemption notice is given, such obligation,
or substantial likelihood, to pay such Additional Amounts must remain in effect.

                  In addition, at any time and from time to time prior to June
30, 2000, the Company may redeem up to 35% of the aggregate principal amount of
Securities with the proceeds of one or more Public Equity Offerings (with the
cash proceeds thereof to the extent actually contributed to the Company)
following which there is a Public Market, at a redemption price (expressed as a
percentage of principal amount) of 110.5% plus accrued interest to the
redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the related interest payment date);
PROVIDED, HOWEVER, that at least $100 million aggregate principal amount of the
Securities and $45 million aggregate principal amount of the Second Priority
Notes must remain outstanding after each such redemption.


                  6.  MANDATORY REDEMPTION

                  In the event an Owner elects to terminate its Building
Contract because of a material breach thereof by the Builders (including a
failure to pay liquidated damages for any delay in the delivery of the related
Vessel), the Securities will be subject to mandatory redemption in part, on a
pro rata basis, in an aggregate principal amount equal to the Allocated
Principal Amount of the Securities for such Vessel and for each other Vessel
that has not been accepted by its related Owner as of the date of such
termination, at a redemption price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest to and including the date of
redemption (subject to the right of a Holder of record on the relevant record
date to receive interest due on the relevant Interest Payment Date), upon the
earlier to occur of (a) the receipt of the Refund Amount with respect to the
related Building Contract(s) and (b) 60 days after the termination of such
Building Contract(s) by the related Owner(s).

                  If a Vessel is subject to Total Loss, the Securities will be
subject to mandatory redemption in part, on a pro rata basis, in an aggregate
principal amount equal 

<PAGE>


to the Allocated Principal Amount of the Securities for such Vessel, at a
redemption price equal to 101% of the principal amount thereof, plus accrued and
unpaid interest to the date of redemption (subject to the right of a Holder of
record on the relevant record date to receive interest due on the relevant
Interest Payment Date), upon the earlier to occur of (a) the receipt of the
Insurance Proceeds with respect to such Total Loss and (b) 60 days after such
Total Loss was deemed to have occurred.


                  7.  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 of Securities to be
redeemed at his registered address. Securities in denominations larger than
$1,000 may be redeemed in part but only in whole multiples of $1,000. If money
sufficient to pay the redemption price of and accrued interest on all Securities
(or portions thereof) to be redeemed on the redemption date is deposited with
the Paying Agent on or before the redemption date, on and after such date
interest ceases to accrue on such Securities (or such portions thereof) called
for redemption.


                  8.  OFFERS TO PURCHASE

                  On each Available Cash Payment Date, the Company will be
required, to the extent of Available Cash on such Available Cash Payment Date,
to make an Available Cash Offer to each Holder of Securities to purchase such
Holder's Securities in whole or in part, at a price equal to 102% of the
principal amount thereof plus accrued and unpaid interest to the date of
purchase (subject to the right of Holders of record on the relevant record date
to receive interests due on the related Interest Payment Date) as provided in,
and subject to the terms of, the Indenture. Upon a Change of Control, any Holder
of Securities will have the right to cause the Company to purchase all or any
part of the Securities of such Holder at a purchase price equal to 101% of the
principal amount of the Securities to be purchased plus accrued interest to the
date of repurchase (subject to the right of Holders of record on the relevant
record date to receive interest due on the related Interest Payment Date) as
provided in, and subject to the terms of, the Indenture.

<PAGE>

                  9.  GUARANTEE

                  The payment by the Company of the principal of, and premium
and interest on, the Securities is fully and unconditionally guaranteed on a
joint and several senior basis by the Owners.


                  10.  SECURITY

                  The Securities will initially be secured by the Collateral
delivered on the Issue Date. Upon the occurrence of a Delivery Date with respect
to a Vessel the Securities will thereafter be secured by a first priority ship
mortgage on such Vessel and all other Collateral delivered on the Delivery Date
of such Vessel. The Securities will also have the benefit of the Letter of
Credit.


                  11.  DENOMINATIONS; TRANSFER; EXCHANGE

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


                  12.  PERSONS DEEMED OWNERS

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


                  13.  UNCLAIMED MONEY

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

<PAGE>

                  14.  DISCHARGE AND DEFEASANCE

                  Subject to certain conditions, the Company at any time may
terminate some or all of its and the Guarantors' obligations under the
Securities, the Security Agreements and the Indenture if the Company deposits
with the Trustee money or U.S. Government Obligations for the payment of
principal and interest on the Securities to redemption or maturity, as the case
may be.


                  15.  AMENDMENT, WAIVER

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount of the Securities and (ii)
any default or noncompliance with any provision may be waived with the written
consent of the Holders of a majority in principal amount of the Securities.
Subject to certain exceptions set forth in the Indenture, without the consent of
any Securityholder, the Company, the Guarantors and the Trustee may amend the
Indenture, the Security Agreements or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 5 of the Indenture,
or to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add additional guarantees with respect to the
Securities or to provide additional security for the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company or
the Guarantors, or to comply with any request of the SEC in connection with
qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Securityholder.


                  16.  DEFAULTS AND REMEDIES

                  Under the Indenture, Events of Default include (i) default for
30 days in payment of interest on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon redemption pursuant to paragraph 5
or 6 of the Securities, upon required purchase, upon acceleration or otherwise,
or failure by the Company or the Guarantors to redeem or purchase Securities
when required; (iii) failure by the Company to comply with other agreements in
the Indenture or the Securities, in certain cases subject to notice and lapse of
time; (iv) certain accelerations (including failure to pay within any grace
period after final maturity) of other Indebtedness of Holdings, the 


<PAGE>

Company or the Owners if the amount accelerated (or so unpaid) exceeds $5.0
million; (v) certain events of bank- ruptcy or insolvency with respect to
Holdings, the Company or the Owners; (vi) certain judgments or decrees for the
payment of money in excess of $5.0 million, (vii) certain events or defaults
with respect to the Guarantees or the Security Agreements and (ix) the failure
by the Designated Owners to hold certain prescribed percentages of Voting Stock
and Capital Stock of Holdings. If an Event of Default occurs and is continuing,
the Trustee or the Holders of at least 25% in principal amount of the Securities
may declare all the Securities to be due and payable immediately. Certain events
of bankruptcy or insolvency are Events of Default which will result in the
Securities being due and payable immediately upon the occurrence of such Events
of Default.

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


                  17.  TRUSTEE DEALINGS WITH THE COMPANY

                  Subject to certain limitations imposed by the Act, the Trustee
under the Indenture, in its individual or any other capacity, may become the
owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its Affiliates with the same rights it would have if it were

               PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

                              Ladies and Gentlemen:

                Upon the terms and subject to the conditions of the Exchange 
Offer, the undersigned hereby tenders to the Companies the principal amount of
the Existing First Priority Notes indicated above. Subject to, and effective
upon, the acceptance for exchange of such Existing First Priority Notes tendered
hereby, the undersigned hereby exchanges, assigns and transfers to, or upon the
order of, the Companies all right, title and interest in and to such Existing
First Priority Notes as are being tendered hereby, including all rights to
accrued and unpaid interest thereon as of the Expiration Date. The undersigned
hereby irrevocably constitutes and appoints the First Priority Notes Exchange
Agent the true and lawful agent and attorney-in-fact of the undersigned (with
full knowledge that said First Priority Notes Exchange Agent acts as the agent
of the Companies in connection with the Exchange Offer) to cause the Existing
First Priority Notes to be assigned, transferred and exchanged. The undersigned
represents and warrants that it has full power and authority to tender,
exchange, assign and transfer the Existing First Priority Notes and to acquire
First Priority Exchange Notes issuable upon the exchange of such tendered
Existing First Priority Notes, and that when the same are accepted for exchange,
the Companies will acquire good and unencumbered title to the tendered Existing
First Priority Notes, free and clear of all liens, restrictions, charges and
encumbrances and not subject to any adverse claim.

                The undersigned acknowledges that this Exchange Offer is being 
made in reliance on interpretations by the staff of the Securities and Exchange
Commission set forth in no-action letters issued to third parties. Based on such
interpretations, the Companies believe that the First Priority Exchange Notes
issued in exchange for the Existing First Priority Notes pursuant to the
Exchange Offer may be offered for resale, resold and otherwise transferred by
holders thereof (other than any such holder that is an "affiliate" of the
Companies within the meaning of Rule 405 under the Securities Act of 1933, as
amended (the "Securities Act"), or a broker-dealer tendering Existing First
Priority Notes acquired directly from the Companies or an affiliate thereof for
its own account) without compliance with the registration and prospectus
delivery provisions of the Securities Act, provided that such Exchange First
Priority Notes are acquired in the ordinary course of such holders' business and
such holders are not engaged in and do not intend to engage in a distribution of
Exchange First Priority Notes and have no arrangement or understanding with any
person to participate in a distribution of Exchange First Priority Notes.

                By signing or electronically confirming this Letter of
Transmittal, the undersigned represents to the Companies that (i) the Exchange
First Priority Notes acquired pursuant to the Exchange Offer are being obtained
in the ordinary course of such holder's business, (ii) the undersigned is not
engaged in, and does not intend to engage in, a distribution of the Exchange
First Priority Notes and has no arrangement or understanding with any person to
participate in a distribution of the Exchange First Priority Notes, and (iii)
the undersigned is neither an "affiliate" of the Companies within the meaning of
Rule 405 under the Securities Act nor a broker-dealer tendering Existing First
Priority Notes acquired directly from the Companies or an affiliate thereof for
its own account. If the undersigned is an affiliate within the meaning of Rule
405 under the

Securities Act, it represents that it will comply with the registration and
prospectus delivery requirements of the Securities Act to the extent applicable.

                If the undersigned is a broker-dealer that will receive Exchange
First Priority Notes for its own account in exchange for Existing First Priority
Notes, it represents that the Existing First Priority Notes to be exchanged for
the Exchange First Priority Notes were acquired by it as a result of
market-making activities or other trading activities and acknowledges that it
will deliver aprospectus in connection with any resale of such Exchange First
Priority 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.

                The undersigned also warrants that it will, upon request, 
execute and deliver any additional documents deemed by the First Priority Notes
Exchange Agent or the Companies to be necessary or desirable to complete the
exchange, assignment and transfer of tendered Existing First Priority Notes or
transfer ownership of such Existing First Priority Notes on the account books
maintained by a book-entry transfer facility.

                The Exchange Offer is subject to certain conditions set forth in
the Prospectus under the caption "The Exchange Offer--Conditions." The
undersigned recognizes that as a result of these conditions (which may be
waived, in whole or in part, by the Companies), as more particularly set forth
in the Prospectus, the Companies may not be required to exchange any of the
Existing First Priority Notes tendered hereby and, in such event, the Existing
First Priority Notes not exchanged will be returned to the undersigned at the
address shown below the signature of the undersigned.

                All authority herein conferred or agreed to be conferred shall 
survive the death or incapacity of the undersigned and every obligation of the
undersigned hereunder shall be binding upon the heirs, personal representatives,
successors and assigns of the undersigned. Tendered Existing First Priority
Notes may be withdrawn at any time prior to the Expiration Date.

Registration Instructions" or the box entitled "Special Delivery Instructions"

Notes delivered in exchange for tendered Existing First Priority Notes, and any

                         FORMING PART OF THE TERMS AND
                        CONDITIONS OF THE EXCHANGE OFFER

          1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES.

                  All physically delivered Existing First Priority Notes or
confirmation of any book-entry transfer to the First Priority Notes Exchange
Agent's account at a book-entry transfer facility of Existing First Priority
Notes tendered by book-entry transfer, as well as a properly completed and duly
executed copy of this Letter of Transmittal or facsimile thereof (or electronic
confirmation thereof), and any other documents required by this Letter of
Transmittal, must be received by the First Priority Notes Exchange Agent at any
of its addresses set forth herein on or prior to the Expiration Date. THE METHOD

ANY OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH BOOKENTRY TRANSFER, IS

DELIVERY WILL BE VALID ONLY WHEN ACTUALLY RECEIVED BY THE FIRST PRIORITY NOTES
EXCHANGE AGENT. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE
AN OVERNIGHT OR HAND DELIVERY SERVICE. IF DELIVERY IS BY MAIL, IT IS SUGGESTED
THAT REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, BE USED.
IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO PERMIT TIMELY DELIVERY.

                  No alternative, conditional, irregular or contingent tenders
will be accepted. 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 Existing First Priority Notes for exchange.

DELIVERY TO AN ADDRESS OTHER THAN AS SET FORTH HEREIN, OR INSTRUCTIONS VIA
FACSIMILE TO A NUMBER OTHER THAN THE ONE SET FORTH HEREIN, WILL NOT CONSTITUTE
VALID DELIVERY.

2.       GUARANTEED DELIVERY PROCEDURES.

                  Holders who wish to tender their Existing First Priority Notes
and who do not hold their Existing First Priority Notes through a book-entry
transfer facility, but whose Existing First Priority Notes are not immediately
available or who cannot deliver their Existing First Priority Notes, the Letter
of Transmittal or any other required documents to the First Priority Notes
Exchange Agent (or complete the procedures for book-entry transfer) prior to the
Expiration Date, may effect a tender if:

         (a)      the tender is made through 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 (an "Eligible Institution");

         (b)      prior to the Expiration Date, the First Priority Notes
                  Exchange Agent receives from such Eligible Institution a
                  properly completed and duly executed Notice of Guaranteed
                  Delivery (by facsimile transmission, mail or hand delivery)
                  setting forth the name and address of the Holder, the
                  certificate number(s) of such Existing

                                       10

<PAGE>



                  First Priority Notes and the principal amount of Existing
                  First Priority Notes tendered, stating that the tender is
                  being made thereby and guaranteeing what, within five New York
                  Stock Exchange trading days after the Expiration Date or the
                  execution of the Notice of Guaranteed Delivery, the Letter of
                  Transmittal (or facsimile thereof), together with the
                  certificate(s) representing the Existing First Priority Notes
                  (or a confirmation of book-entry transfer of such Existing
                  First Priority Notes into the First Priority Notes Exchange
                  Agent's account at the BookEntry Transfer Facility) and any
                  other documents required by the Letter of Transmittal, will be
                  deposited by the Eligible Institution with the First Priority
                  Notes Exchange Agent; and

         (c)      such properly completed and executed Letter of Transmittal (or
                  facsimile thereof), as well as the certificate(s) representing
                  all tendered Existing First Priority Notes in proper form for
                  transfer (or a confirmation of book-entry transfer of such
                  Existing First Priority Notes into the First Priority Notes
                  Exchange Agent's account at the Book-Entry Transfer Facility)
                  and all other documents required by the Letter of Transmittal,
                  are received by the First Priority Notes Exchange Agent within
                  five New York Stock Exchange trading days after the Expiration
                  Date.

                  Upon request to the First Priority Notes Exchange Agent, a
Notice of Guaranteed Delivery will be sent to Holders who wish to tender their
Existing First Priority Notes according to the guaranteed delivery procedures
set forth above. Any Holder who wishes to tender Existing First Priority Notes
pursuant to the guaranteed delivery procedures described above must ensure that
the First Priority Notes Exchange Agent receives the Notice of Guaranteed
Delivery relating to such Existing First Priority Notes prior to the Expiration
Date. Failure to complete the guaranteed delivery procedures outlined above will
not, of itself, affect the validity or effect a revocation of any Letter of
Transmittal form properly completed and executed by a Holder who attempted to
use the guaranteed delivery procedures.

3.       PARTIAL TENDERS; WITHDRAWALS.

                  If less than the entire principal amount of Existing First
Priority Notes evidenced by a submitted certificate is tendered, the tendering
Holder should fill in the principal amount tendered in the column entitled
"Principal Amount Tendered" of the box entitled "Description of Existing First
Priority Notes Tendered Hereby." A newly issued Existing Note for the principal
amount of Existing First Priority Notes submitted but not tendered will be sent
to such Holder as soon as practicable after the Expiration Date. Subject to
minimum denominations of $100,000 and integral multiples of $1,000 in excess
thereof, $1,000 principal amount of Exchange First Priority Notes is offered in
exchange for each $1,000 principal amount of Existing First Priority Notes. All
Existing First Priority Notes delivered to the First Priority Notes Exchange
Agent will be deemed to have been tendered in full unless otherwise indicated.

                  Existing First Priority Notes tendered pursuant to the
Exchange Offer may be withdrawn at any time prior to 5:00 p.m., New York City
time, on the Expiration Date, after which time tenders of Existing First
Priority Notes are irrevocable. To be effective, a written or facsimile
transmission notice of withdrawal (or a written or electronic transmission
notice of withdrawal through DTC's Automated Tender Offer Program ("ATOP") for
DTC participants) must be timely received by the First Priority Notes Exchange
Agent. Any such notice of

                                       11

<PAGE>



withdrawal must (i) specify the name of the person having deposited the Existing
First Priority Notes to be withdrawn (the "Depositor"), (ii) identify the
Existing First Priority Notes to be withdrawn (including the registration
number(s) and principal amount of such Existing First Priority Notes or, in the
case of Existing First Priority Notes transferred by book-entry transfer, the
name and number of the account at the Book-Entry Transfer Facility to be
credited), (iii) be signed or confirmed by the Holder in the same manner as the
original signature on or confirmation of this Letter of Transmittal (including
any required signature guarantees) or be accompanied by documents of transfer
sufficient to have the Trustee with respect to the Existing First Priority Notes
register the transfer of such Existing First Priority Notes into the name of the
person withdrawing the tender and (iv) specify the name in which any such
Existing First Priority Notes are to be registered, if different from that of
the Depositor. If Existing First Priority Notes have been delivered pursuant to
procedures for book-entry transfer, any notice of withdrawal must otherwise
comply with DTC's procedures. All questions as to the validity, form and
eligibility (including time of receipt) of such notices will be determined by
Navigator Gas Transport, whose determination shall be final and binding on all
parties. Any Existing First Priority Notes so withdrawn will be deemed not to
have been validly tendered for purposes of the Exchange Offer and no Exchange
First Priority Notes will be issued with respect thereto unless the Existing
First Priority Notes so withdrawn are validly retendered. Any Existing First
Priority Notes which have been tendered but which 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 Existing First Priority Notes may be retendered by
following the procedures for tender described above.

4.       SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS AND
         ENDORSEMENTS; GUARANTEE OF SIGNATURES.

                  If this Letter of Transmittal is signed by the registered
Holder(s) of the Existing First Priority Notes tendered hereby, the signature
must correspond with the name(s) as written on the face of the certificates
without alteration or enlargement or any change whatsoever. If this Letter of
Transmittal is signed by a participant in the Book-Entry Transfer Facility, the
signature must correspond with the name as it appears on the security position
listing as the owner of the Existing First Priority Notes.

                  If any of the Existing First Priority 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 Existing First Priority Notes registered in
different names are tendered, it will be necessary to complete, sign and submit
as many separate copies of this Letter of Transmittal as there are different
registrations of Existing First Priority Notes.

                  Signatures of this Letter of Transmittal or a notice of
withdrawal, as the case may be, must be guaranteed by an Eligible Institution
unless the Existing First Priority Notes tendered hereby are tendered (i) by a
registered Holder who has not completed the box entitled "Special Registration
Instructions" or "Special Delivery Instructions" on the Letter of Transmittal or
(ii) for the account of an Eligible Institution.

                  If this Letter of Transmittal is signed by the registered
Holder or Holders of Existing First Priority Notes (which term, for the purposes
described herein, shall include a


                                       12

<PAGE>



participant in the Book-Entry Transfer Facility whose name appears on a security
listing as the owner of the Existing First Priority Notes) listed and tendered
hereby, no endorsements of the tendered Existing First Priority Notes or
separate written instruments of transfer or exchange are required. In any other
case, the registered Holder (or acting Holder) must either properly endorse the
Existing First Priority Notes or transmit properly completed bond powers with
this Letter of Transmittal (in either case, executed exactly as the name(s) of
the registered Holder(s) appear(s) on the Existing First Priority Notes, and,
with respect to a participant in the Book-Entry Transfer Facility whose name
appears on a security position listing as the owner of Existing First Priority
Notes, exactly as the name of the participant appears on such security position
listing), with the signature on the Existing First Priority Notes or bond power
guaranteed by an Eligible Institution (except where the Existing First Priority
Notes are tendered for the account of an Eligible Institution).

                  If this Letter of Transmittal, any certificates or separate
written instruments of transfer or exchange are signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations or others
acting in a fiduciary or representative capacity, such persons should so
indicate when signing, and, unless waived by Navigator Gas Transport, proper
evidence satisfactory to Navigator Gas Transport of their authority so to act
must be submitted.

5.       SPECIAL REGISTRATION AND DELIVERY INSTRUCTIONS.

                  Tendering Holders should indicate, in the applicable box, the
name and address (or account at the Book-Entry Transfer Facility) in which the
Exchange First Priority Notes or substitute Existing First Priority Notes for
principal amounts not tendered or not accepted for exchange are to be issued (or
deposited), if different from the names and addresses or accounts of the person
signing this Letter of Transmittal. In the case of issuance in a different name,
the employer identification number or social security number of the person named
must also be indicated and the tendering Holder should complete the applicable
box.

                  If no instructions are given, the Exchange First Priority
Notes (and any Existing First Priority Notes not tendered or not accepted) will
be issued in the name of and sent to the acting Holder of the Existing First
Priority Notes or deposited at such Holder's account at the Book-Entry Transfer
Facility.

6.       TRANSFER TAXES.

                  Navigator Gas Transport shall pay all transfer taxes, if any,
applicable to the transfer and exchange of Existing First Priority Notes
pursuant to the Exchange Offer. If, however, certificates representing the
Exchange First Priority Notes or the Existing First Priority Notes for principal
amounts not tendered or accepted for exchange are to be delivered to, or are to
be issued in the name of, any person other than the registered Holder of the
Existing First Priority Notes tendered, or if tendered Existing First Priority
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 the Existing First Priority Notes pursuant to the Exchange
Offer, then the amount of any such transfer taxes (whether imposed on the
registered Holder or any other person) will be payable by the tendering Holder.
If satisfactory evidence of payment of such taxes or exception therefrom is not
submitted herewith, the amount of such

                                       13

<PAGE>



transfer taxes will be collected from the tendering Holder by the First Priority
Notes Exchange Agent.

                  Except as provided in this Instruction 6, it will not be
necessary for transfer stamps to be affixed to the Existing First Priority Notes
listed in this Letter of Transmittal.

7.       WAIVER OF CONDITIONS.

                  Navigator Gas Transport reserve the right, in its reasonable
judgment, to waive, in whole or in part, any of the conditions to the Exchange
Offer set forth in the Prospectus.

8.       MUTILATED, LOST, STOLEN OR DESTROYED NOTES.

                  Any Holder whose Existing First Priority Notes have been
mutilated, lost, stolen or destroyed should contact the First Priority Notes
Exchange Agent at the address indicated above for further instructions.

9.       REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.

                  Questions relating to the procedure for tendering as well as
requests for additional copies of the Prospectus and this Letter of Transmittal,
may be directed to the First Priority Notes Exchange Agent at the address and
telephone number(s) set forth above. In addition, all questions relating to the
Exchange Offer, as well as requests for assistance or additional copies of the
Prospectus and this Letter of Transmittal, may be directed to Navigator Gas
Transport, c/o Cambridge Fund Management, LLC, Park Avenue Tower, 65 East 55th
Street, Suite 3000, New York, New York, 10022, telephone number: (212) 661-9541.

10.      VALIDITY AND FORM.

                  All questions as to the validity, form, eligibility (including
time of receipt), acceptance of tendered Existing First Priority Notes and
withdrawal of tendered Existing First Priority Notes will be determined by
Navigator Gas Transport in its sole discretion, which determination will be
final and binding. Navigator Gas Transport reserves the absolute right to reject
any and all Existing First Priority Notes not properly tendered or any Existing
First Priority Notes the acceptance of which would, in the opinion of counsel
for Navigator Gas Transport, be unlawful. Navigator Gas Transport also reserves
the right to waive any defects, irregularities or conditions of tender as to
particular Existing First Priority Notes. Navigator Gas Transport's
interpretation of the terms and conditions of the Exchange Offer (including the
instructions in this Letter of Transmittal) will be final and binding on all
parties. Unless waived, any defects or irregularities in connection with tenders
of Existing First Priority Notes must be cured within such time as Navigator Gas
Transport shall determine. Although Navigator Gas Transport intends to notify
Holders of defects or irregularities with respect to tenders of Existing First
Priority Notes, none of Navigator Gas Transport, the First Priority Notes
Exchange Agent or any other person shall incur any liability for failure to give
such notification. Tenders of Existing First Priority Notes will not be deemed
to have been made until such defects or irregularities have been cured or
waived. Any Existing First Priority Notes received by the First Priority Notes
Exchange Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or

                                       14

<PAGE>



waived will be returned by the First Priority Notes Exchange Agent to the
tendering Holders as soon as practicable following the Expiration Date.

                            IMPORTANT TAX INFORMATION

                  Under federal income tax law, a Holder tendering Existing
First Priority Notes is required to provide the First Priority Notes Exchange
Agent with such Holder's correct TIN on Substitute Form W-9 below. If such
Holder is an individual, the TIN is the Holder's social security number. The
Certificate of Awaiting Taxpayer Identification Number should be completed if
the tendering Holder has not been issued a TIN and has applied for a number or
intends to apply for a number in the near future. If the First Priority Notes
Exchange Agent is not provided with the correct TIN, the Holder may be subject
to a $50 penalty imposed by the Internal Revenue Service. In addition, payments
that are made to such Holder with respect to tendered Existing First Priority
Notes may be subject to backup withholding.

                  Certain Holders (including, among others, all domestic
corporations and certain foreign individuals and foreign entities) are not
subject to these backup withholding and reporting requirements. Such a Holder
who satisfies one or more of the conditions set forth in Part 2 of the
Substitute Form W-9 should execute the certification following such Part 2. In
order for a foreign Holder to qualify as an exempt recipient, that Holder must
submit to the First Priority Notes Exchange Agent a properly completed Internal
Revenue Service Form W-8, signed under penalties of perjury, attesting to that
Holder's exempt status. Such forms can be obtained from the First Priority Notes
Exchange Agent.

                  If backup withholding applies, the First Priority Notes
Exchange Agent is required to withhold 31% of any amounts otherwise payable to
the Holder. Backup withholding is not an additional tax. Rather, the 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 that are made to a
Holder with respect to Existing First Priority Notes tendered for exchange, the
Holder is required to notify the First Priority Notes Exchange Agent of his or
her correct TIN by completing the form herein certifying that the TIN provided
on Substitute Form W-9 is correct (or that such Holder is awaiting a TIN) and
that (i) each Holder is exempt, (ii) such Holder has not been notified by the
Internal Revenue Service that he or she is subject to backup withholding as a
result of failure to report all interest or dividends or (iii) the Internal
Revenue Service has notified such Holder that he or she is no longer subject to
backup withholding.

WHAT NUMBER TO GIVE THE FIRST PRIORITY NOTES EXCHANGE AGENT

                  Each Holder is required to give the First Priority Notes
Exchange Agent the social security number or employer identification number of
the record Holder(s) of the Existing First Priority Notes. If Existing First
Priority Notes are in more than one name or are not in the name of the actual
Holder, consult the instructions on Internal Revenue Service Form W-9, which may

                                       15

<PAGE>


be obtained from the First Priority Notes Exchange Agent, for additional
guidance on which number to report.

CERTIFICATE OF AWAITING TAXPAYER IDENTIFICATION NUMBER

                  If the tendering Holder has not been issued a TIN and has
applied for a number or intends to apply for a number in the near future, write
"Applied For" in the space for the TIN on Substitute Form W-9, sign and date the
form and the Certificate of Awaiting Taxpayer Identification Number and return
them to the First Priority Notes Exchange Agent. If such certificate is
completed and the First Priority Notes Exchange Agent is not provided with the
TIN within 60 days, the First Priority Notes Exchange Agent will withhold 31% of
all payments made thereafter until a TIN is provided to the First Priority Notes
Exchange Agent.

                  IMPORTANT: THIS LETTER OF TRANSMITTAL OR A FACSIMILE THEREOF
(TOGETHER WITH THE EXISTING FIRST PRIORITY NOTES OR CONFIRMATION OF BOOK-ENTRY
TRANSFER AND ALL OTHER REQUIRED DOCUMENTS) OR A NOTICE OF GUARANTEED DELIVERY
MUST BE RECEIVED BY THE FIRST PRIORITY NOTES EXCHANGE AGENT ON OR PRIOR TO THE
EXPIRATION DATE.

               PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

                Upon the terms and subject to the conditions of the Exchange
Offer, the undersigned hereby tenders to the Companies the principal amount of
the Existing Second Priority Notes indicated above. Subject to, and effective
upon, the acceptance for exchange of such Existing Second Priority Notes
tendered hereby, the undersigned hereby exchanges, assigns and transfers to, or
upon the order of, the Companies all right, title and interest in and to such
Existing Second Priority Notes as are being tendered hereby, including all
rights to accrued and unpaid interest thereon as of the Expiration Date. The
undersigned hereby irrevocably constitutes and appoints the Second Priority
Notes Exchange Agent the true and lawful agent and attorney-in-fact of the
undersigned (with full knowledge that said Second Priority Notes Exchange Agent
acts as the agent of the Companies in connection with the Exchange Offer) to
cause the Existing Second Priority Notes to be assigned, transferred and
exchanged. The undersigned represents and warrants that it has full power and
authority to tender, exchange, assign and transfer the Existing Second Priority
Notes and to acquire Second Priority Exchange Notes issuable upon the exchange
of such tendered Existing Second Priority Notes, and that when the same are
accepted for exchange, the Companies will acquire good and unencumbered title to
the tendered Existing Second Priority Notes, free and clear of all liens,
restrictions, charges and encumbrances and not subject to any adverse claim.

                The undersigned acknowledges that this Exchange Offer is being 
made in reliance on interpretations by the staff of the Securities and Exchange
Commission set forth in no-action letters issued to third parties. Based on such
interpretations, the Companies believe that the Second Priority Exchange Notes
issued in exchange for the Existing Second Priority Notes pursuant to the
Exchange Offer may be offered for resale, resold and otherwise transferred by
holders thereof (other than any such holder that is an "affiliate" of the
Companies within the meaning of Rule 405 under the Securities Act of 1933, as
amended (the "Securities Act"), or a broker-dealer tendering Existing Second
Priority Notes acquired directly from the Companies or an affiliate thereof for
its own account) without compliance with the registration and prospectus
delivery provisions of the Securities Act, provided that such Exchange Second
Priority Notes are acquired in the ordinary course of such holders' business and
such holders are not engaged in and do not intend to engage in a distribution of
Exchange Second Priority Notes and have no arrangement or understanding with any
person to participate in a distribution of Exchange Second Priority Notes.

                By signing or electronically confirming this Letter of
Transmittal, the undersigned represents to the Companies that (i) the Exchange
Second Priority Notes acquired pursuant to the Exchange Offer are being obtained
in the ordinary course of such holder's business, (ii) the undersigned is not
engaged in, and does not intend to engage in, a distribution of the Exchange
Second Priority Notes and has no arrangement or understanding with any person to
participate in a distribution of the Exchange Second Priority Notes, and (iii)
the undersigned is neither an "affiliate" of the Companies within the meaning of
Rule 405 under the Securities Act nor a broker- dealer tendering Existing Second
Priority Notes acquired directly from the Companies or an


                                        5

affiliate thereof for its own account. If the undersigned is an affiliate within
the meaning of Rule 405 under the Securities Act, it represents that it will
comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable.

                If the undersigned is a broker-dealer that will receive Exchange
Second Priority Notes for its own account in exchange for Existing Second
Priority Notes, it represents that the Existing Second Priority Notes to be
exchanged for the Exchange Second Priority Notes were acquired by it as a result
of market-making activities or other trading activities and acknowledges that it
will deliver a prospectus in connection with any resale of such Exchange Second
Priority 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.

                The undersigned also warrants that it will, upon request,
execute and deliver any additional documents deemed by the Second Priority Notes
Exchange Agent or the Companies to be necessary or desirable to complete the
exchange, assignment and transfer of tendered Existing Second Priority Notes or
transfer ownership of such Existing Second Priority Notes on the account books
maintained by a book-entry transfer facility.

                The Exchange Offer is subject to certain conditions set forth
in the Prospectus under the caption "The Exchange Offer--Conditions." The
undersigned recognizes that as a result of these conditions (which may be
waived, in whole or in part, by the Companies), as more particularly set forth
in the Prospectus, the Companies may not be required to exchange any of the
Existing Second Priority Notes tendered hereby and, in such event, the Existing
Second Priority Notes not exchanged will be returned to the undersigned at the
address shown below the signature of the undersigned.

                  All authority herein conferred or agreed to be conferred
shall survive the death or incapacity of the undersigned and every obligation of
the undersigned hereunder shall be binding upon the heirs, personal
representatives, successors and assigns of the undersigned. Tendered Existing
Second Priority Notes may be withdrawn at any time prior to the Expiration Date.

                   Unless otherwise indicated in the box entitled "Special
Registration Instructions" or the box entitled "Special Delivery Instructions"
in this Letter of Transmittal, certificates for all Exchange Second Priority
Notes delivered in exchange for tendered Existing Second Priority Notes, and any
Existing Second Priority Notes delivered herewith but not exchanged, will be
registered in the name of the undersigned and shall be delivered to the
undersigned at the address shown below the signature of the undersigned. If an
Exchange Note is to be issued to a person other than the person(s) signing this
Letter of Transmittal, or if the Exchange Note is to be mailed to someone other
than the person(s) signing this Letter of Transmittal or to the person(s)
signing this Letter of Transmittal at an address different than the address
shown on this Letter of Transmittal, the appropriate boxes of this Letter of
Transmittal should be completed. IF EXISTING SECOND PRIORITY NOTES ARE

REGISTRATION INSTRUCTIONS" OR THE BOX ENTITLED "SPECIAL DELIVERY INSTRUCTIONS"

PRIORITY NOTES EXCHANGE AGENT. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED
THAT HOLDERS USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IF DELIVERY IS BY MAIL,
IT IS SUGGESTED THAT REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, BE USED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO PERMIT
TIMELY DELIVERY.

                  No alternative, conditional, irregular or contingent tenders
will be accepted. 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 Existing Second Priority Notes for exchange.

DELIVERY TO AN ADDRESS OTHER THAN AS SET FORTH HEREIN, OR INSTRUCTIONS VIA
FACSIMILE TO A NUMBER OTHER THAN THE ONE SET FORTH HEREIN, WILL NOT CONSTITUTE
VALID DELIVERY.

2.       GUARANTEED DELIVERY PROCEDURES.

                  Holders who wish to tender their Existing Second Priority
Notes and who do not hold their Existing Second Priority Notes through a
book-entry transfer facility, but whose Existing Second Priority Notes are not
immediately available or who cannot deliver their Existing Second Priority
Notes, the Letter of Transmittal or any other required documents to the Second
Priority Notes Exchange Agent (or complete the procedures for book-entry
transfer) prior to the Expiration Date, may effect a tender if:

         (a)      the tender is made through 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 (an "Eligible Institution");

         (b)      prior to the Expiration Date, the Second Priority Notes
                  Exchange Agent receives from such Eligible Institution a
                  properly completed and duly executed Notice of Guaranteed
                  Delivery (by facsimile transmission, mail or hand delivery)
                  setting forth the name and address of the Holder, the
                  certificate number(s) of such Existing


                                       10

<PAGE>



                  Second Priority Notes and the principal amount of Existing
                  Second Priority Notes tendered, stating that the tender is
                  being made thereby and guaranteeing what, within five New York
                  Stock Exchange trading days after the Expiration Date or the
                  execution of the Notice of Guaranteed Delivery, the Letter of
                  Transmittal (or facsimile thereof), together with the
                  certificate(s) representing the Existing Second Priority Notes
                  (or a confirmation of book-entry transfer of such Existing
                  Second Priority Notes into the Second Priority Notes Exchange
                  Agent's account at the Book-Entry Transfer Facility) and any
                  other documents required by the Letter of Transmittal, will be
                  deposited by the Eligible Institution with the Second Priority
                  Notes Exchange Agent; and

         (c)      such properly completed and executed Letter of Transmittal (or
                  facsimile thereof), as well as the certificate(s)
                  representing all tendered Existing Second Priority Notes in
                  proper form for transfer (or a confirmation of book-entry
                  transfer of such Existing Second Priority Notes into the
                  Second Priority Notes Exchange Agent's account at the
                  Book-Entry Transfer Facility) and all other documents
                  required by the Letter of Transmittal, are received by the
                  Second Priority Notes Exchange Agent within five New York
                  Stock Exchange trading days after the Expiration Date.

                  Upon request to the Second Priority Notes Exchange Agent, a
Notice of Guaranteed Delivery will be sent to Holders who wish to tender their
Existing Second Priority Notes according to the guaranteed delivery procedures
set forth above. Any Holder who wishes to tender Existing Second Priority Notes
pursuant to the guaranteed delivery procedures described above must ensure that
the Second Priority Notes Exchange Agent receives the Notice of Guaranteed
Delivery relating to such Existing Second Priority Notes prior to the Expiration
Date. Failure to complete the guaranteed delivery procedures outlined above will
not, of itself, affect the validity or effect a revocation of any Letter of
Transmittal form properly completed and executed by a Holder who attempted to
use the guaranteed delivery procedures.

3.       PARTIAL TENDERS; WITHDRAWALS.

                  If less than the entire principal amount of Existing Second
Priority Notes evidenced by a submitted certificate is tendered, the tendering
Holder should fill in the principal amount tendered in the column entitled
"Principal Amount Tendered" of the box entitled "Description of Existing Second
Priority Notes Tendered Hereby." A newly issued Existing Note for the principal
amount of Existing Second Priority Notes submitted but not tendered will be sent
to such Holder as soon as practicable after the Expiration Date. Subject to
minimum denominations of $100,000 and integral multiples of $1,000 in excess
thereof, $1,000 principal amount of Exchange Second Priority Notes is offered in
exchange for each $1,000 principal amount of Existing Second Priority Notes. All
Existing Second Priority Notes delivered to the Second Priority Notes Exchange
Agent will be deemed to have been tendered in full unless otherwise indicated.

                  Existing Second Priority Notes tendered pursuant to the
Exchange Offer may be withdrawn at any time prior to 5:00 p.m., New York City
time, on the Expiration Date, after which time tenders of Existing Second
Priority Notes are irrevocable. To be effective, a written or facsimile
transmission notice of withdrawal (or a written or electronic transmission
notice of withdrawal through DTC's Automated Tender Offer Program ("ATOP") for
DTC participants)


                                       11

<PAGE>



must be timely received by the Second Priority Notes Exchange Agent. Any such
notice of withdrawal must (i) specify the name of the person having deposited
the Existing Second Priority Notes to be withdrawn (the "Depositor"), (ii)
identify the Existing Second Priority Notes to be withdrawn (including the
registration number(s) and principal amount of such Existing Second Priority
Notes or, in the case of Existing Second Priority Notes transferred by
book-entry transfer, the name and number of the account at the Book-Entry
Transfer Facility to be credited), (iii) be signed or confirmed by the Holder in
the same manner as the original signature on or confirmation of this Letter of
Transmittal (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Trustee with respect to the
Existing Second Priority Notes register the transfer of such Existing Second
Priority Notes into the name of the person withdrawing the tender and (iv)
specify the name in which any such Existing Second Priority Notes are to be
registered, if different from that of the Depositor. If Existing Second Priority
Notes have been delivered pursuant to procedures for book-entry transfer, any
notice of withdrawal must otherwise comply with DTC's procedures. All questions
as to the validity, form and eligibility (including time of receipt) of such
notices will be determined by the Companies, whose determination shall be final
and binding on all parties. Any Existing Second Priority Notes so withdrawn will
be deemed not to have been validly tendered for purposes of the Exchange Offer
and no Exchange Second Priority Notes will be issued with respect thereto unless
the Existing Second Priority Notes so withdrawn are validly retendered. Any
Existing Second Priority Notes which have been tendered but which 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 Existing Second Priority
Notes may be retendered by following the procedures for tender described above.

4.       SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS AND
         ENDORSEMENTS; GUARANTEE OF SIGNATURES.

                  If this Letter of Transmittal is signed by the registered
Holder(s) of the Existing Second Priority Notes tendered hereby, the signature
must correspond with the name(s) as written on the face of the certificates
without alteration or enlargement or any change whatsoever. If this Letter of
Transmittal is signed by a participant in the Book-Entry Transfer Facility, the
signature must correspond with the name as it appears on the security position
listing as the owner of the Existing Second Priority Notes.

                  If any of the Existing Second Priority 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 Existing Second Priority Notes registered in
different names are tendered, it will be necessary to complete, sign and submit
as many separate copies of this Letter of Transmittal as there are different
registrations of Existing Second Priority Notes.

                  Signatures of this Letter of Transmittal or a notice of
withdrawal, as the case may be, must be guaranteed by an Eligible Institution
unless the Existing Second Priority Notes tendered hereby are tendered (i) by a
registered Holder who has not completed the box entitled "Special Registration
Instructions" or "Special Delivery Instructions" on the Letter of Transmittal or
(ii) for the account of an Eligible Institution.

<PAGE>



                  If this Letter of Transmittal is signed by the registered
Holder or Holders of Existing Second Priority Notes (which term, for the
purposes described herein, shall include a participant in the Book-Entry
Transfer Facility whose name appears on a security listing as the owner of the
Existing Second Priority Notes) listed and tendered hereby, no endorsements of
the tendered Existing Second Priority Notes or separate written instruments of
transfer or exchange are required. In any other case, the registered Holder (or
acting Holder) must either properly endorse the Existing Second Priority Notes
or transmit properly completed bond powers with this Letter of Transmittal (in
either case, executed exactly as the name(s) of the registered Holder(s)
appear(s) on the Existing Second Priority Notes, and, with respect to a
participant in the Book- Entry Transfer Facility whose name appears on a
security position listing as the owner of Existing Second Priority Notes,
exactly as the name of the participant appears on such security position
listing), with the signature on the Existing Second Priority Notes or bond power
guaranteed by an Eligible Institution (except where the Existing Second Priority
Notes are tendered for the account of an Eligible Institution).

                  If this Letter of Transmittal, any certificates or separate
written instruments of transfer or exchange are signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations or others
acting in a fiduciary or representative capacity, such persons should so
indicate when signing, and, unless waived by Navigator Gas Transport, proper
evidence satisfactory to Navigator Gas Transport of its authority so to act must
be submitted.

5.       SPECIAL REGISTRATION AND DELIVERY INSTRUCTIONS.

                  Tendering Holders should indicate, in the applicable box, the
name and address (or account at the Book-Entry Transfer Facility) in which the
Exchange Second Priority Notes or substitute Existing Second Priority Notes for
principal amounts not tendered or not accepted for exchange are to be issued (or
deposited), if different from the names and addresses or accounts of the person
signing this Letter of Transmittal. In the case of issuance in a different name,
the employer identification number or social security number of the person named
must also be indicated and the tendering Holder should complete the applicable
box.

                  If no instructions are given, the Exchange Second Priority
Notes (and any Existing Second Priority Notes not tendered or not accepted) will
be issued in the name of and sent to the acting Holder of the Existing Second
Priority Notes or deposited at such Holder's account at the Book-Entry Transfer
Facility.

6.       TRANSFER TAXES.

                  Navigator Gas Transport shall pay all transfer taxes, if any,
applicable to the transfer and exchange of Existing Second Priority Notes
pursuant to the Exchange Offer. If, however, certificates representing the
Exchange Second Priority Notes or the Existing Second Priority Notes for
principal amounts not tendered or accepted for exchange are to be delivered to,
or are to be issued in the name of, any person other than the registered Holder
of the Existing Second Priority Notes tendered, or if tendered Existing Second
Priority 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 the Existing Second Priority Notes pursuant to
the Exchange Offer, then the amount of any such transfer taxes (whether imposed
on the registered Holder or any other person) will be payable by the tendering
Holder. If satisfactory


                                       13

<PAGE>



evidence of payment of such taxes or exception therefrom is not submitted
herewith, the amount of such transfer taxes will be collected from the tendering
Holder by the Second Priority Notes Exchange Agent.

                  Except as provided in this Instruction 6, it will not be
necessary for transfer stamps to be affixed to the Existing Second Priority
Notes listed in this Letter of Transmittal.

7.       WAIVER OF CONDITIONS.

                  Navigator Gas Transport reserves the right, in its reasonable
judgment, to waive, in whole or in part, any of the conditions to the Exchange
Offer set forth in the Prospectus.

8.       MUTILATED, LOST, STOLEN OR DESTROYED NOTES.

                  Any Holder whose Existing Second Priority Notes have been
mutilated, lost, stolen or destroyed should contact the Second Priority Notes
Exchange Agent at the address indicated above for further instructions.

9.       REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.

                  Questions relating to the procedure for tendering as well as
requests for additional copies of the Prospectus and this Letter of Transmittal,
may be directed to the Second Priority Notes Exchange Agent at the address and
telephone number(s) set forth above. In addition, all questions relating to the
Exchange Offer, as well as requests for assistance or additional copies of the
Prospectus and this Letter of Transmittal, may be directed to Navigator Gas
Transport, c/o Cambridge Fund Management, LLC, Park Avenue Tower, 65 East 55th
Street, Suite 3000, New York, New York, 10022, telephone number: (212) 661-9541.

10.      VALIDITY AND FORM.

                  All questions as to the validity, form, eligibility (including
time of receipt), acceptance of tendered Existing Second Priority Notes and
withdrawal of tendered Existing Second Priority Notes will be determined by
Navigator Gas Transport in its sole discretion, which determination will be
final and binding. Navigator Gas Transport reserves the absolute right to reject
any and all Existing Second Priority Notes not properly tendered or any Existing
Second Priority Notes the acceptance of which would, in the opinion of counsel
for Navigator Gas Transport, be unlawful. Navigator Gas Transport also reserves
the right to waive any defects, irregularities or conditions of tender as to
particular Existing Second Priority Notes. Navigator Gas Transport's
interpretation of the terms and conditions of the Exchange Offer (including the
instructions in this Letter of Transmittal) will be final and binding on all
parties. Unless waived, any defects or irregularities in connection with tenders
of Existing Second Priority Notes must be cured within such time as Navigator
Gas Transport shall determine. Although Navigator Gas Transport intends to
notify Holders of defects or irregularities with respect to tenders of Existing
Second Priority Notes, none of Navigator Gas Transport, the Second Priority
Notes Exchange Agent or any other person shall incur any liability for failure
to give such notification. Tenders of Existing Second Priority Notes will not be
deemed to have been made until such defects or irregularities have been cured or
waived. Any Existing Second Priority Notes received by the Second Priority Notes
Exchange Agent that are not properly tendered and as to which the defects


                                       14

<PAGE>


or irregularities have not been cured or waived will be returned by the Second
Priority Notes Exchange Agent to the tendering Holders as soon as practicable
following the Expiration Date.

                            IMPORTANT TAX INFORMATION

                  Under federal income tax law, a Holder tendering Existing
Second Priority Notes is required to provide the Second Priority Notes Exchange
Agent with such Holder's correct TIN on Substitute Form W-9 below. If such
Holder is an individual, the TIN is the Holder's social security number. The
Certificate of Awaiting Taxpayer Identification Number should be completed if
the tendering Holder has not been issued a TIN and has applied for a number or
intends to apply for a number in the near future. If the Second Priority Notes
Exchange Agent is not provided with the correct TIN, the Holder may be subject
to a $50 penalty imposed by the Internal Revenue Service. In addition, payments
that are made to such Holder with respect to tendered Existing Second Priority
Notes may be subject to backup withholding.

                  Certain Holders (including, among others, all domestic
corporations and certain foreign individuals and foreign entities) are not
subject to these backup withholding and reporting requirements. Such a Holder
who satisfies one or more of the conditions set forth in Part 2 of the
Substitute Form W-9 should execute the certification following such Part 2. In
order for a foreign Holder to qualify as an exempt recipient, that Holder must
submit to the Second Priority Notes Exchange Agent a properly completed Internal
Revenue Service Form W-8, signed under penalties of perjury, attesting to that
Holder's exempt status. Such forms can be obtained from the Second Priority
Notes Exchange Agent.

                  If backup withholding applies, the Second Priority Notes
Exchange Agent is required to withhold 31% of any amounts otherwise payable to
the Holder. Backup withholding is not an additional tax. Rather, the 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 that are made to a
Holder with respect to Existing Second Priority Notes tendered for exchange, the
Holder is required to notify the Second Priority Notes Exchange Agent of his or
her correct TIN by completing the form herein certifying that the TIN provided
on Substitute Form W-9 is correct (or that such Holder is awaiting a TIN) and
that (i) each Holder is exempt, (ii) such Holder has not been notified by the
Internal Revenue Service that he or she is subject to backup withholding as a
result of failure to report all interest or dividends or (iii) the Internal
Revenue Service has notified such Holder that he or she is no longer subject to
backup withholding.

WHAT NUMBER TO GIVE THE SECOND PRIORITY NOTES EXCHANGE AGENT

                  Each Holder is required to give the Second Priority Notes
Exchange Agent the social security number or employer identification number of
the record Holder(s) of the Existing Second Priority Notes. If Existing Second
Priority Notes are in more than one name or are not in the name of the actual
Holder, consult the instructions on Internal Revenue Service Form W-9,


                                       15

<PAGE>


which may be obtained from the Second Priority Notes Exchange Agent, for
additional guidance on which number to report.

CERTIFICATE OF AWAITING TAXPAYER IDENTIFICATION NUMBER

                  If the tendering Holder has not been issued a TIN and has
applied for a number or intends to apply for a number in the near future, write
"Applied For" in the space for the TIN on Substitute Form W-9, sign and date the
form and the Certificate of Awaiting Taxpayer Identification Number and return
them to the Second Priority Notes Exchange Agent. If such certificate is
completed and the Second Priority Notes Exchange Agent is not provided with the
TIN within 60 days, the Second Priority Notes Exchange Agent will withhold 31%
of all payments made thereafter until a TIN is provided to the Second Priority
Notes Exchange Agent.

                  IMPORTANT: THIS LETTER OF TRANSMITTAL OR A FACSIMILE THEREOF
(TOGETHER WITH THE EXISTING SECOND PRIORITY NOTES OR CONFIRMATION OF BOOK-ENTRY
TRANSFER AND ALL OTHER REQUIRED DOCUMENTS) OR A NOTICE OF GUARANTEED DELIVERY
MUST BE RECEIVED BY THE SECOND PRIORITY NOTES EXCHANGE AGENT ON OR PRIOR TO THE
EXPIRATION DATE.
