                       ENFORCEABILITY OF CIVIL LIABILITIES

     We and each of the Owners are organized under the laws of the Isle of Man.
A substantial portion of our assets and the assets of the Owners 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 us 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 of our directors and directors of the Owners are
residents of jurisdictions other than the United States, and all or a
significant portion of the assets of these 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 these 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. We and the Owners have 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 them in connection with the offering and sale of the notes.

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

                       WHERE YOU CAN FIND MORE INFORMATION

     We have filed with the SEC a registration statement on Form F-4 under the
Securities Act of 1933, as amended, with respect to our offering of the new
notes. This prospectus, which constitutes part of the registration statement,
does not contain all of the information in the registration statement. You will

at Citicorp Center, 500 West Madison Street (Suite 1400), Chicago, Illinois
60661. You may obtain copies from the Public Reference Section of the SEC at 450
Fifth Street, N.W., Washington, D.C. 20549 at prescribed rates. Please call the

Securities Exchange Act of 1934, as amended, prescribing the furnishing and

     We are not currently subject to the periodic reporting and other
informational requirements of the Exchange Act. We will furnish to you and the
trustees, for so long as any of the new notes remain outstanding, and file with
the SEC, or cause to be so filed as part of our financial statements (1) all
quarterly and annual financial information that would be required to be

file those forms, including a "Management's Discussion and Analysis of Financial
Condition and Results of Operations," (2) with respect to the annual information
only, a report thereon by independent public accountants and (3) all reports
that would be required to be filed with the SEC on Form 8-K if we were required
to file those reports.

     Copies of the documents mentioned in this prospectus can be obtained
without charge by any recipient of this prospectus by contacting us at Navigator

                               PROSPECTUS SUMMARY

     This summary highlights selected information from this prospectus and does
not contain all of the information that is important to you. For a more complete
understanding of the exchange offer, we encourage you to read all of the
information in this prospectus carefully, including the "Risk Factors" section,
before you exchange your old notes. Unless otherwise indicated, all references
in this prospectus to "we," "us," "ours" or "Navigator Gas Transport" mean
Navigator Gas Transport PLC. We will use the word "Owner" to refer to any of
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 and the word "Owners" to refer to all of them. Navigator Holdings PLC is
the parent company of Navigator Gas Transport. We will use the words "Navigator
Holdings" to refer to Navigator Holdings PLC. We will use the words "the
Company" to refer together to Navigator Gas Transport, the Owners and Navigator
Holdings.

                                   THE COMPANY

     We and the Owners were formed in 1997 for the purpose of building and
operating a fleet of five state-of-the-art 22,000 cubic meter semi-refrigerated
ethylene-capable gas carriers. The vessels are designed to transport the entire
range of petrochemical gases, including ethylene, propylene, vinyl chloride
monomer butadiene and crude C4, as well as liquefied petroleum gases 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 of the Owners will have four separate gas cargo tanks,
segregated pumping and piping systems and two separate deck tanks, allowing each
vessel to carry up to three separate temperature controlled cargoes
simultaneously.

     When constructed, the Owners' 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 vessels'
capabilities will minimize operating costs, reduce voyage times and maximize
vessel utilization. The vessels' larger cargo capacities, compared to the
existing ethylene-capable fleet, offer significant economies of scale,
especially for long-haul transport.

     Each Owner will own one and only one vessel. We will own all of the Owners.

     We issued the old notes. We loaned the proceeds to the Owners to fund the
construction of their vessels, to pay certain expenses and to pay interest on
the notes while the vessels are constructed. The Owners, fully and
unconditionally, guaranteed the old notes and will guarantee, fully and
unconditionally, the new notes. The vessels will be constructed by Jiangnan
Shipyard and China Shipbuilding Trading Company, Limited under the technical
supervision of Martime Asia Ltd., in coordination with Germanischer Lloyd, an
independent vessel classification society. Jiangnan and China Shipbuilding are
together referred to as the "builders" in this prospectus. Martime Asia is an
affiliate of Gesellschaft fur Konzeption und Betreuung privater Investitionen
mbH ("GEBAB").

     Our principal executive office and registered office is located at 1 Castle
Street, Castletown, Isle of Man, IM9 1LF, and our telephone number at that
address is 011-44-1-62-4824011.

                               THE EXCHANGE OFFER

     On August 7, 1997, we issued $217,000,000 aggregate principal amount of
10-1/2% First Priority Ship Mortgage Notes Due 2007 and 87,000 units consisting
of $87,000,000 aggregate principal amount of 12% Second Priority Ship Mortgage
Notes and warrants to purchase 666,420 shares of common stock of Navigator
Holdings to the initial purchasers in a private offering exempt from the
registration requirements of the Securities Act.

     o    We are offering $1,000 principal amount of new 10 1/2% First Priority
          Ship Mortgage Notes in exchange for each $1,000 principal amount of
          old 10 1/2% First Priority Ship Mortgage Notes.

     o    We are offering $1,000 principal amount of new 12% Second Priority
          Ship Mortgage Notes in exchange for each $1,000 principal amount of
          old 12% Second Priority Ship Mortgage Notes.

     The new 10 1/2% First Priority Ship Mortgage Notes are substantially
identical to the old 10 1/2% First Priority Ship Mortgage Notes and the new 12%
Second Priority Ship Mortgage Notes are substantially identical to the old 12%
Second Priority Ship Mortgage Notes, except that:

     o    the new notes will be freely transferable, except as described in this
          prospectus;

     o    the new notes will not contain any legend restricting their transfer;

     o    holders of the new notes will not be entitled to certain rights of the
          holders of the original notes under the registration rights agreement;
          and

     o    the new notes will not contain any provisions regarding the payment of
          additional interest for failure to register the notes.

     We believe you can transfer the new notes without complying with the
registration and prospectus delivery provisions of the Securities Act if you:

     o    acquire the new notes in the ordinary course of your business;

     o    are not and do not intend to become engaged in a distribution of the
          new notes;

     o    are not an affiliate of ours;

     o    are not a broker-dealer that acquired old notes directly from us; and


                                       4
<PAGE>

     o    are not a broker-dealer that acquired old notes as a result of
          market-making or other trading activities.

     If any of these conditions are not satisfied and you transfer any new notes
without delivering a proper prospectus or without qualifying for an exemption,
you may be liable under the Securities Act. If you are a broker-dealer that
receives new notes for its own account in exchange for old notes, which you
acquired as a result of market-making activities or other trading activities,
you must acknowledge that you will deliver a prospectus in connection with any
resale of those new notes. See "Plan of Distribution."

                                                               o each vessel when delivered;

                                  RISK FACTORS

     Before you participate in the exchange offer, you should be aware that
there are various risks, including those described below. You should carefully
consider these risk factors, together with the other information in this
prospectus, before deciding to exchange your old notes for new notes in the
exchange offer.

     YOU MAY SUFFER IF OUR BUSINESS FAILS BECAUSE WE, THE OWNERS AND NAVIGATOR
HOLDINGS EXIST SOLELY FOR THE PURPOSE OF OWNING, OPERATING, AND/OR GUARANTEEING
OBLIGATIONS IN CONNECTION WITH THE VESSELS AND THE NOTES.

     The activity of Navigator Holdings is limited to owning our capital stock
and pledging our capital stock as collateral. Our activity 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 loans
to the Owners. The activity of the Owners is limited to guaranteeing the new
notes and the old notes, guaranteeing our obligations under the Letter of Credit
Reimbursement Agreement, owning, operating and maintaining the vessels and
fulfilling their obligations under the indentures, the Security Agreements and
the Letter of Credit Reimbursement Agreement. The Owners must make payments to
us in order for us to meet our payment obligations on the notes. We have no
material assets other than the stock of the Owners. On and after a vessel is
delivered, the Owners' sources of funds will be earnings on the vessels already
delivered, earnings on investments of certain funds and the proceeds from any
insurance covering loss to the vessels. We cannot assure you that the Owners
will generate sufficient earnings to enable us to meet our payment obligations.
We have no operating history or financial statements for any period prior to the
offerings of the old notes.

     NEITHER WE, THE OWNERS NOR NAVIGATOR HOLDINGS HAVE AN OPERATING HISTORY
WHICH YOU CAN RELY ON TO PREDICT OUR SUCCESS.

     We, the Owners and Navigator Holdings were incorporated in 1997 for the
purpose of establishing, owning and financing the Owners. We, the Owners and
Navigator Holdings have limited operating histories and financial data. This
prospectus contains consolidated financial statements of Navigator Holdings and
its subsidiaries. Because of the limited operations of us, the Owners and
Navigator Holdings, it will be difficult for you to determine and for us to
predict how successful we may be.

     WE CANNOT PREDICT WHAT OUR REVENUES GENERATED BY THE VESSELS WILL BE.

     Historically, the revenues generated by gas carriers have been cyclical,
with volatility in their profitability resulting from changes in supply and
demand. The cargo transportation rates received by the Owners will be primarily
dependent upon:

     o    the supply of vessels capable of transporting the types of cargoes the
          Owners intend to transport; and

     o    the level of demand for the seaborne transport of the cargoes the
          Owners intend to transport.


                                       15
<PAGE>

          These factors will be influenced by:

          o    global and regional economic conditions;

          o    increases and decreases in the industrial production of and
               demand for the types of cargo the Owners intend to transport and
               the products made from the cargoes;

          o    political changes and armed conflicts in the regions traveled by
               the vessels and the regions where the cargoes are produced;

          o    developments in international trade;

          o    changes in seaborne and other transportation patterns; and

          o    geopolitical events that interrupt production, trade routes or
               consumption of the cargoes we intend to transport or products
               made from the cargoes.

     Because many of the factors influencing the supply of and demand and trade
patterns for tonnage and cargo are unforeseeable and beyond our control, we
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 on the vessels.

     WE MAY BE UNABLE TO SATISFY OUR OBLIGATIONS UNDER THE INDENTURES IN THE
EVENT OF NON-PERFORMANCE BY THE BUILDERS AND PROVIDERS OF THE BUILDING CONTRACT
GUARANTEES AND THE PERFORMANCE BONDS, AND/OR THE UNFAVORABLE OUTCOME OF
ARBITRATION RESULTING FROM THE EVENT.

     Each Owner may cancel its contract to build its vessel if the builders
commit an event of default. Events of default by the builders include the
failure by the builders to:

          o    make timely payment of liquidated damages to the Owners for
               delays in the delivery of the vessels beyond 210 days after the
               delivery date stated in the building contract;

          o    deliver the vessels by March 31, 2001; or

          o    construct the vessels in conformity with certain specifications.

     Each building contract also provides for the automatic termination of the
building contract if, prior to the contractual delivery date:

          o    a vessel is seized by the Chinese government; or

          o    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


                                       16
<PAGE>

          o    a total loss occurs with respect to a vessel; and

          o    in each case, the builders do not elect to continue performing
               under the building contract.

     If any building contract is cancelled by the Owner or automatically
terminated, each other Owner that has not accepted delivery of its vessel will
be deemed to have also cancelled its building contract through operation of
cross-default provisions.

     If an Owner cancels a building contract pursuant to its terms or a building
contract is automatically terminated, the builders must pay the Owner a
specified refund. If the builders do not pay the Owner the refund, the guarantor
of the building contract and the performance bond guarantors have severally and
not jointly guaranteed the payment of specified amounts which together will
equal the specified refund. The refund together with the funds held in the
Pre-Funding Account and the Capitalized Interest Account will be used to pay the
principal amount of the notes allocated to the cancelled vessel, plus any
accrued and unpaid interest on the notes allocated to the vessel, plus certain
fees and expenses incurred in connection with this redemption. If the builders
fail to pay the Owners the specified refund and the Owners do not receive the
amounts payable under the building contract guarantee and the performance bonds,
we will not have sufficient funds to redeem the principal amount of the notes
allocated to the cancelled vessel.

     If a dispute arises under a building contract, the Owner and the builders
have agreed to submit the dispute to arbitration by either Germanischer Lloyd or
the London Maritime Arbitrators Association, as may be mutually agreed to by the
parties involved. The arbitrator may in any particular dispute decide in favor
of the builders and, as a result, delay or eliminate the Owner's right to
receive payment of (1) any liquidated damages, whether by an adjustment in the
purchase price of the vessel or a cash payment, or (2) the specified refund. If
we need the liquidated damages or the specified refund to make interest payments
on, or to redeem, the First Priority Notes or the Second Priority Notes, we may
not have sufficient funds to satisfy our obligations under the indentures.

     THE VALUE OF THE VESSELS ARE VOLATILE AND MAY RESULT IN INSUFFICIENT
COLLATERAL TO SATISFY OUR PAYMENT OBLIGATIONS TO YOU AS A NOTEHOLDER.

     When the Owners accept the vessels under the building contracts, the
guarantees will be secured by a mortgage on each vessel granted to the
collateral agent. We cannot assure you that the value of each vessel will at any
time equal or exceed the principal amount of the notes allocated to the
particular vessel. The fair market value of the vessels can be expected to
fluctuate, depending upon:

          o    general economic and market conditions affecting the shipping
               industry;

          o    competition from other shipping companies;

          o    demand for various types and sizes of vessels; and


                                       17
<PAGE>

          o    other modes of transportation.

     If the collateral agent sells a vessel after an event of default, we cannot
assure you that the proceeds from the sale would be sufficient to redeem the
principal amount of the notes allocated to the particular vessel or that any
buyers would be available under the circumstances in which the sale would occur.
We are not required under the indentures to maintain any minimum value of any
vessel. We cannot assure you that the future value of a vessel will not be
considerably less than its acquisition cost or the principal amount of the notes
allocated to the particular vessel. If we owe amounts under the Letter of Credit
Reimbursement Agreement, then the issuer of the letter of credit will have a
claim to the proceeds of any sale of a vessel prior to the claim of the holders
of the notes. In the event of a dispute, depending upon the laws of the
applicable jurisdiction, the extent to which the mortgages on the vessels may be
enforced and the extent to which the mortgages on the vessels will have priority
over the claims of other creditors is limited. If the proceeds from a sale of
the vessels is not sufficient to satisfy payments due on the notes, the holders
of the notes will have only unsecured claims against our remaining assets, if
any. See "The Mortgages."

     WE DEPEND ON KEY PERSONNEL OF OUR MANAGER AND GEBAB AND/OR ITS AFFILIATES,
THE LOSS OF WHOM MAY CAUSE DELAYS AND HAVE AN ADVERSE EFFECT ON OUR BUSINESS.

     Our operations are dependent to some degree upon the efforts of a small
number of key management and operating personnel of our manager, Navigator Gas
Management Limited (the "Manager"), and at Martime Asia and MarLink
Schiffahrtskontor GmbH, affiliates of GEBAB, the loss of whom could adversely
affect us. Although there are other qualified managers in the seaborne gas
carrier industry who we may hire, we cannot assure you that we will be able to
hire qualified managers on favorable terms, if at all. We cannot assure you that
the loss of these persons will not have an adverse impact on our business.

     OUR INDUSTRY HAS OPERATORS WITH GREATER RESOURCES THAN WE DO WHICH MAY MAKE
IT DIFFICULT FOR US TO COMPETE.

     The number of our competitors in the seaborne trade of petrochemical gases
is small and consists of a few large and experienced operators with greater
financial resources than we have. Since we will be a new participant in this
field and we do not have an operating history, we may not be able to participate
successfully in the seaborne gas carrier industry. See "Gas Carrier Industry."
Also, the designer of our gas plant, Tractebel Gas Engineering, and its
affiliates, are not restricted from engineering, designing and constructing gas
storage and transportation plants and equipment for our competitors.

     BECAUSE WE ENGAGE IN INTERNATIONAL OPERATIONS, OUR BUSINESS COULD SUFFER IF
THERE IS A CHANGE IN INTERNATIONAL RELATIONS.

     Our revenues from operation of the vessels are expected to be derived
primarily from foreign operations and is subject to risks inherent in doing
business abroad. Future hostilities or other political instability in the
regions in which we operate could affect our activity and could adversely affect
our business and results of operations.


                                       18

     Because the ports at which the Owners' vessels will call have not yet been
determined, we cannot identify specifically any risks associated with a
particular country or region that may affect our business and operations and the
magnitude of the risks that may be involved in those areas.

     COMPLYING WITH OR THE FAILURE TO COMPLY WITH ENVIRONMENTAL REGULATIONS
COULD BE COSTLY AND MAY HARM OUR BUSINESS.

     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, 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. The Oil Pollution Act applies to
all vessels that trade in the United States or its territories or possessions or
operate in United States waters, even if the 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 the Oil Pollution
Act, without the limitations on the amount of liability contained in the federal
statutes.

     CERCLA and the Oil Pollution Act each require vessel owners and operators
to furnish the United States Coast Guard evidence of financial responsibility
sufficient to meet their potential liability. Insurance has been one of the
principal methods used to satisfy the 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 within the territorial waters of the United States, the Owner must
furnish evidence of financial responsibility with respect to the vessels to the
Coast Guard as required by the Final Rule. If the Owner is unable to comply with
the Final Rule, its vessel will not be permitted to enter United States
territorial waters. We believe that we and the Owners will have the financial
ability to comply with the Final Rule.

     In addition, the International Maritime Organization (the "IMO"), a
specialized 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.


                                       19

     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.
Because the ports at which the Owners' vessels will call have not yet been
determined, we cannot identify specifically any particular state or country's
environmental regulations that will affect the Owners and us.

     THE OWNERS MAY LOSE THEIR VESSELS OR SUFFER SIGNIFICANT LOSSES DUE TO ACTS
OF NATURE OR OTHER CATASTROPHES WHICH OUR INSURANCE MAY NOT COVER.

     The operation of any ocean-going vessel carries 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. The terms of the mortgages do not permit the vessels to be
employed in any manner or for any purpose excepted by the insurance on the
vessels. In the past, political conflicts have disrupted shipping in regions
where the vessels are expected to operate. Vessels trading in these regions have
also been subject to acts of terrorism and piracy. The occurrence of any event
may result in increased costs or the loss of revenues or assets, including the
total loss of a vessel.

     We intend to maintain insurance consistent with industry standards against
these risks. Each Owner currently intends to maintain $65 million of hull and
machinery loss insurance and loss of hire insurance providing coverage of
$28,000 per day. However, we cannot assure you that all risks will be adequately
insured against, that any particular claim will be paid out of insurance or that
the Owners 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 us or the loss of income resulting from a vessel being removed from
operations. Even if insurance proceeds are paid to us to cover the financial
losses incurred following the occurrence of one of these events, we cannot
assure you that our business reputation, and therefore our ability to obtain
future charters, will not be materially adversely affected by an event. An
impact on our business reputation could have a material adverse effect on our
business and results of operations. See "The Mortgages--Insurance."

     WE MAY EXPERIENCE DIFFICULTIES ENFORCING OUR MORTGAGES IN JURISDICTIONS
WITH DIFFERENT ENFORCEMENT PROCEDURES AND LIEN PRIORITIES.

     Each vessel will be registered under the laws of the Republic of Liberia or
the Isle of Man. The mortgages will be recorded pursuant to the laws of the
Republic of Liberia or the Isle of Man and will create preferred ship mortgage
liens under the maritime law of those jurisdictions. Historically, Liberian and
Isle of Man ship mortgages have been enforced in major commercial ports
throughout the world. However, the priority that the mortgages will have against
the claims of other lien creditors in an enforcement proceeding is generally
determined by, and will vary in accordance with, the laws of the country where a
proceeding is brought.


                                       20
<PAGE>

Generally, 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 and Isle
of Man 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,
that the vessel will be located in a jurisdiction having the same mortgage
enforcement procedures and lien priorities as, for example, Liberia, Isle of Man
or the United States. In the 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. We cannot assure you that an attempt by the collateral agent to
effect control will be successful.

     WE ARE SUBJECT TO FRAUDULENT CONVEYANCE STATUTES THAT MAY RESULT IN A
DECLARATION OF INSOLVENCY WHICH COULD INTERFERE WITH OUR ABILITY TO MEET OUR
PAYMENT OBLIGATIONS.

     Our granting of the security interest in the collateral could be subject to
review under relevant fraudulent conveyance statutes and other applicable
insolvency laws in a bankruptcy or other proceeding involving us and Navigator
Holdings. Due to the nature of the business of us and Navigator 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
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 we, each of the Owners and Navigator Holdings are incorporated, if a court
were to find that, with respect to us, any Owner or Navigator Holdings, at the
time a security interest in the collateral is granted, we, any Owner or
Navigator Holdings:

          o    made the grant of the security interest with actual intent to
               prefer or defraud any present or future creditor;

          o    received less than a reasonably equivalent value or fair
               consideration for the grant of the security interest; or

          o    intended to incur, or believed that it would incur, debts beyond
               its ability to pay as they matured,

then the court could void the grant of the security interest in whole or in
part. To the extent that a grant of the security interest by us, any Owner or
Navigator Holdings exceeds the consideration received, the determination of
whether the grant of the security interest in question is a fraudulent
conveyance depends on:


                                       21
<PAGE>

          o    whether the grant of the security interest so exceeds the value
               and benefit received by us, the Owner or Navigator Holdings that,
               at least to the extent of the excess, we, the Owner or Navigator
               Holdings did not receive reasonably equivalent value or fair
               consideration for the grant of the security interest; and, if so,

          o    whether following the valuation of the assets and liabilities of
               us, or Navigator Holdings, it is determined that we, the Owners
               or Navigator Holdings are or have been rendered insolvent. There
               can be no assurance that a court, viewing the transaction in
               hindsight, would determine that we, the Owners or Navigator
               Holdings received fair value for its grant of the security
               interest, or were not rendered insolvent as a result of the
               grant. We, the Owners and Navigator Holdings believe that we will
               have received proper consideration for the grant of the security
               interest and that none of us, the Owners or Navigator Holdings
               will be rendered insolvent by the contemplated grants of the
               security interest.

     SINCE WE ARE INCORPORATED IN THE ISLE OF MAN, IT MAY BE DIFFICULT TO
ENFORCE JUDGMENTS AGAINST US.

     We, the Owners and Navigator Holdings are all 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 United
States' courts and predicated upon United States' securities laws.

     IN THE EVENT OF A CHANGE OF CONTROL, WE MAY HAVE INSUFFICIENT FUNDS TO MEET
OUR PURCHASE OBLIGATIONS.

     Pursuant to the indentures, in the event of a change of control, we will be
required to offer to purchase the new notes and any untendered old notes, in
whole or in part, at a price equal to 101% of the principal amount of the notes
as described under "Description of the New Notes--Mandatory Offers to Purchase
New Notes--Offer to Purchase Upon Change of Control." Since we have not provided
any reserve of credit support to fund a change of control offer note purchase,
we cannot assure you that we will have sufficient funds to purchase notes in
these circumstances.

     YOU MAY NOT BE ABLE TO SELL YOUR NEW NOTES BECAUSE NO PUBLIC MARKET MAY
EXIST FOR THEM.

     The old notes are currently owned by a relatively small number of
beneficial owners. The old 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 new notes. The new notes will
constitute a new issue of securities with no established trading market.
Although the new 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, we do not intend to
list the new notes on any national securities exchange or to seek admission to
trade on the Nasdaq National Market. Accordingly,


                                       22
<PAGE>

we cannot assure you that an active public or other market exists or will
develop for the new notes or the degree of liquidity that will exist for them.
See "Plan of Distribution."

     FAILURE TO COMPLY WITH THE EXCHANGE OFFER PROCEDURES MAY RESULT IN YOUR
INABILITY TO PARTICIPATE IN THE EXCHANGE OFFER.

          o    To exchange your old notes for new notes you must give us or our
               exchange agents on a timely basis a properly completed and duly
               executed letter of transmittal, or an agreement to be bound by
               one, and all other required documents.

          o    If you want to exchange your old notes you should allow
               sufficient time to ensure timely delivery.

          o    We are under no duty to give notification of defects or
               irregularities with respect to tenders of old notes for exchange.

          o    Old notes that are not tendered or are tendered but not accepted
               will, after the exchange offer, continue to be subject to the
               existing restrictions on transfer, and after the exchange offer,
               the registration rights under the registration rights agreement
               generally will terminate.

          o    If you tender old notes in the exchange offer for the purpose of
               participating in a distribution of the new notes, you may be
               deemed to have received restricted securities and will be
               required to comply with the registration and prospectus delivery
               requirements of the Securities Act in connection with any resale
               transaction by you. If you are a broker-dealer and you receive
               new notes for your own account in exchange for your old notes,
               and you acquired your old notes as a broker-dealer as a result of
               market-making activities or other trading activities, you must
               acknowledge that you will deliver a prospectus in connection with
               any resale of the new notes. If we accept the old notes tendered
               to us in the exchange offer, the liquidity of untendered and
               tendered but unaccepted old notes could be adversely affected.
               See "The Exchange Offer."

                               THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

     We issued the old notes 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 old notes with
qualified institutional buyers in reliance on Rule 144A under the Securities
Act. As a condition to the purchase of the old notes by the Initial Purchasers,
we entered into the registration rights agreement with the Initial Purchasers.
The registration rights agreement requires us, (1) to file with the SEC a
registration statement under the Securities Act to enable us to exchange the old
notes for new publicly registered notes that are identical in all material
respects to the old notes, (2) to use our reasonable best efforts to cause the
registration statement to become effective under the Securities Act, and (3) to
use our reasonable best efforts to cause the exchange offer to be consummated on
the earliest practical date after the registration statement becomes effective.
We have 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.

     After the exchange offer, if you did not tender your old notes you
generally will not have any further registration rights under the registration
rights agreement, and your old notes will continue to be subject to certain
restrictions on transfer. Accordingly, the liquidity of the market for your old
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, we will accept for exchange any and all old
notes validly tendered and not withdrawn prior to 5:00 p.m., New York City time,
on the expiration date. We will issue up to $217,000,000 principal amount of new
First Priority Notes in exchange for the same principal amount of outstanding
old First Priority Notes accepted in the exchange offer, and up to $87,000,000
principal amount of new Second Priority Notes in exchange for the same principal
amount of outstanding old Second Priority Notes accepted in the exchange offer.
You may tender all or a portion of your old notes pursuant to the exchange
offer. You may tender old notes only in minimum denominations of $100,000 and
integral multiples of $1,000 in excess thereof.

     The form and terms of the new notes will be identical to the form and terms
of the old notes except that:

          o    the new notes have been registered under the Securities Act and
               will not bear legends restricting their transfer; and

          o    holders of the new notes will not be entitled to certain rights
               under the registration rights agreement, which rights generally
               will terminate with the exchange offer.


                                       25
<PAGE>

     The new notes will evidence the same debt as the old notes tendered in
exchange offer and will be entitled to the benefits of the same indentures.

     As of the date of this prospectus, $217,000,000 aggregate principal amount
of the old First Priority Notes and $87,000,000 aggregate principal amount of
the old Second Priority Notes were outstanding and registered in the name of
Cede & Co., as nominee for The Depository Trust Company ("DTC"). We have fixed
the close of business on ________, 1999, 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 required
documents under the Isle of Man laws will be mailed initially.

     In connection with the exchange offer, holders of old notes do not have any
appraisal or dissenters' rights under the General Corporation Law of the Isle of
Man or the indentures. We intend to conduct the exchange offer in accordance
with the applicable requirements of the Exchange Act and the rules and
regulations of the SEC thereunder, including Rule 14e-1.

     We shall be deemed to have accepted validly tendered old notes when, as and
if we have given oral or written notice to the exchange agents. The exchange
agents will act as agent for the tendering holders for the purpose of receiving
the old notes from us.

     If any tendered old notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, the certificates for any unaccepted old notes will be returned,
without expense, to the tendering holder thereof as promptly as practicable
after the expiration date.

     Holders who tender old notes in the exchange offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the letter
of transmittal, transfer taxes with respect to the exchange of notes pursuant to
the exchange offer. We have agreed to pay all fees and expenses in connection
with the exchange offer. See "--Fees and Expenses" and "--Transfer Taxes." Prior
to the expiration date, holders of notes must satisfy the procedures for
tendering their notes. See "--Procedures for Tendering," and "--Guaranteed
Delivery Procedures." We may amend or terminate the exchange offer if any of the
following events occur: (1) the SEC requests that we amend or supplement the
registration statement or this prospectus or that we provide them with
additional information; (2) the SEC issues a stop order suspending the
effectiveness of the registration or the SEC initiates proceedings for that
purpose; (3) we or our counsel receives notice as to the suspension of the
qualification of the notes for sale in any jurisdiction or the initiation or
threatening of any proceeding for that purpose; and (4) the happening of any
event that requires us to make changes in the registration statement or this
prospectus so that there are no untrue statements of material fact or omissions
to state a material fact that is required to be stated, in the case of this
prospectus, in light of the circumstances under which they are made, not
misleading.

EXPIRATION DATE; EXTENSIONS; AMENDMENTS

     The expiration date is 5:00 p.m., New York City time, on __________ 1999
(or later if required by applicable law). If we amend the exchange offer in a
manner we determine to


                                       26
<PAGE>

be a material change, we will promptly disclose the amendment by means of a
supplement to this prospectus that we will distribute to the registered holders
of the old notes or by making a timely release to the Dow Jones News Service,
and, depending upon the significance of the amendment and the manner of
disclosure to the registered holders, we will extend the exchange offer by the
number of days equal to the period between the giving of notice to the delivery
of a supplement to this prospectus.

INTEREST ON THE NEW NOTES

     The new notes will be deemed to accrue interest from June 30, 1999, the
date of the last periodic payment of interest on the old notes. Interest on the
new notes will be payable semi-annually on each June 30 and December 31,
commencing on December 31, 1999. The exchange of old notes for new notes will
not affect interest accrued and due to you on the old notes.

PROCEDURES FOR TENDERING

     Only a holder of old notes may tender old notes in the exchange offer. To
tender in the exchange offer, a holder must either (1) 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 the letter of transmittal or facsimile, together with the old notes and
any other required documents, to the exchange agent, or (2) in the case of a
book-entry transfer, confirm book-entry transfer of the old notes into an equal
principal amount of new notes into the appropriate 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 old 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 old 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 old notes may
also tender in the exchange offer by complying with the procedure set forth
under "--Guaranteed Delivery Procedures."

     The exchange agent will make a request to establish an account for the old
notes at DTC for the exchange offer within two business days after the date of
this prospectus, and any financial institution that is a participant in DTC's
systems may make book-entry delivery of old notes by causing DTC to transfer the
old notes into the appropriate exchange agent's account at DTC in accordance
with DTC's procedures for transfer. However, although delivery of old notes may
be effected through book-entry transfer at DTC, the letter of transmittal or
facsimile, or an agent's message, with any required signature guarantees and any
other required documents, must be received by the exchange agent at one of the
addresses set forth below under "--Exchange Agents" on or before the expiration
date or the guaranteed delivery procedures described below must be complied
with.

     The term "agent's message" means a message, transmitted by DTC to the
exchange agent and forming a part of a book-entry confirmation, which states
that DTC has received an express acknowledgement from the tendering participant
stating that the participant


                                       27
<PAGE>

has received and agrees to be bound by the term of the letter of transmittal,
and that we may enforce the letter of transmittal against the participant.

     By executing or electronically confirming the letter of transmittal, each
holder will make to us the representations set forth below under "--Resale of
New Notes."

     The tender by a holder of old notes and our acceptance of the tender will
constitute agreement between the holder and us in accordance with the terms and
subject to the conditions set forth in this prospectus and in the letter of
transmittal.

     YOUR CHOICE OF THE METHOD OF DELIVERY OF OLD NOTES, THE LETTER OF
TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH DTC, TO
THE EXCHANGE AGENTS IS AT YOUR ELECTION AND RISK. INSTEAD OF DELIVERY BY MAIL,
WE RECOMMEND THAT EACH HOLDER USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL
CASES, YOU SHOULD ALLOW SUFFICIENT TIME TO ASSURE DELIVERY TO THE EXCHANGE
AGENTS BEFORE THE EXPIRATION DATE. DO NOT SEND THE LETTER OF TRANSMITTAL OR
EXISTING NOTES TO US. YOU MAY REQUEST YOUR BROKER, DEALER, COMMERCIAL BANK,
TRUST COMPANY OR NOMINEE TO EFFECT THE ABOVE TRANSACTIONS FOR YOU.

     If you are a beneficial owner of old notes that are registered in the name
of a broker, dealer, commercial bank, trust company or other nominee and you
wish to tender, you should contact the registered holder promptly and instruct
the registered holder to tender on your behalf.

     Your signature on the letter of transmittal or a notice of withdrawal must
be guaranteed by an eligible institution unless your notes are tendered (1) by a
registered holder who has not completed the box entitled "Special Registration
Instructions" or "Special Delivery Instructions" on the letter of transmittal or
(2) for the account of an eligible institution. In the event that your signature
on a letter of transmittal or a notice of withdrawal are required to be
guaranteed, the guarantee must be by an eligible institution. Eligible
institutions are the following: 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.

     If the letter of transmittal is signed by a person other than the
registered holder of old notes listed in the letter of transmittal, the old
notes must be endorsed or accompanied by a properly completed bond power, signed
by the registered holder as the registered holder's name appears on the old
notes with the signature guaranteed by an eligible institution.

     If the letter of transmittal or any old notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, then
these persons should so indicate when signing, and unless waived by us, you must
submit or have submitted with the letter of transmittal evidence satisfactory to
us of their authority to so act.

GUARANTEED DELIVERY PROCEDURES

     Holders not holding through DTC who wish to tender their old notes and (1)
whose old notes are not immediately available, (2) who cannot deliver their old
notes, the letter of transmittal or any other required documents to the exchange
agents, or (3) who cannot complete the procedures for book-entry transfer prior
to the expiration date, may effect a tender if:

          o    the tender is made through an eligible institution;

          o    prior to the expiration date, the exchange agents receive from
               the 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 the old notes being tendered and the
               principal amount of old 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 old notes or a confirmation of
               book-entry transfer of the old notes into the exchange agent's
               account at DTC, and any other documents required by the letter of
               transmittal, will be deposited by the eligible institution with
               the exchange agent; and

          o    properly completed and executed letter of transmittal (or
               facsimile thereof), as well as the certificate(s) representing
               all tendered old notes in proper form for transfer, or a
               confirmation of book-entry transfer of old notes into the
               appropriate exchange agent's account at DTC, and all other
               documents required by the letter of transmittal, are received by
               the exchange agents within five New York Stock Exchange trading
               days after the expiration date.

     Except as otherwise provided herein, tenders of old notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the expiration date.

     To withdraw a tender of old notes in the exchange offer, you must provide a
written or facsimile transmission notice of withdrawal, or a written or
electronic DTC transmission notice of withdrawal for DTC participants, must be
received by the exchange agent at its address set forth herein, or received into
the appropriate exchange agent's account at DTC, prior to 5:00 p.m., New York
City time, on the expiration date.

Your notice of withdrawal must:

          o    specify the name of the person having deposited the old notes to
               be withdrawn;

          o    identify the old notes to be withdrawn;


                                       29
<PAGE>

          o    be signed or confirmed by you in the same manner as the original
               signature on or confirmation of the letter of transmittal by
               which you tendered your old notes, including any required
               signature guarantees, or be accompanied by documents of transfer
               sufficient to have the trustee for your old notes register the
               transfer of your old notes into the name of the person
               withdrawing the tender; and

          o    specify the name in which your old notes are to be registered, if
               different from the name at the time of the deposit. If your old
               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 the notices will be determined by us and our determination will be
final and binding on all parties. Any old notes withdrawn will be deemed not to
have been validly tendered for purposes of the exchange offer and no new notes
will be issued for the old notes unless the old notes so withdrawn are validly
retendered. Any old notes which have been tendered but which are not accepted
for exchange will be returned to the holder without cost to the holder as soon
as practicable after withdrawal, rejection of tender or termination of the
exchange offer. Properly withdrawn old notes may be retendered by following one
of the procedures described above under "--Procedures for Tendering" at any time
prior to the expiration date.

FEES AND EXPENSES

     We are making the principal solicitation by mail. Additional solicitations
may be made by telegraph, telephone or in person by our officers and regular
employees and our affiliates. No additional compensation will be paid to our
officers and employees who engage in soliciting tenders. We have not retained
any dealer-manager in connection with the exchange offer and we will not make
any payments to brokers or others soliciting acceptances of the exchange offer.
We will pay the exchange agents reasonable and customary fees for its services
and will reimburse it for its reasonable out-of-pocket expenses. We will also
pay other


                                       31
<PAGE>

registration expenses, including fees and expenses of the trustees, filing fees,
legal fees, blue sky fees and printing and distribution expenses.

     Our estimated cash expenses to be incurred in connection with the exchange
offer are estimated to be in excess of $450,000.

TRANSFER TAXES

     We will pay all transfer taxes, if any, applicable to the exchange of the
old notes for the new notes in the exchange offer. A tendering holder will pay
transfer taxes if:

          o    certificates representing the new notes or the old 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 old notes tendered;

          o    old notes are registered in the name of any person other than the
               person signing the letter of transmittal; or

          o    a transfer tax is imposed for any reason other than the exchange
               of the notes pursuant to the exchange offer.

ACCOUNTING TREATMENT

     The new notes will be recorded at the same carrying value as the old notes,
which is face value, as reflected in our accounting records on the date of
exchange. Accordingly, no gain or loss for accounting purposes will be
recognized.

RESALE OF NEW NOTES

     Based on interpretations by the staff of the SEC set forth in no-action
letters issued to third parties such as Exxon Capital Holdings Corporation
(available May 13, 1988), Morgan Stanley & Co. Incorporated (available June 5,
1991) and Shearman & Sterling (available July 2, 1993), we believe that new
notes issued pursuant to the exchange offer in exchange for the old notes may be
offered for resale, resold or otherwise transferred by any holder of the new
notes, other than the holder which is an "affiliate" of ours within the meaning
of Rule 405 under the Securities Act, without compliance with the registration
and prospectus delivery provisions of the Securities Act, if the new notes are
acquired in the ordinary course of the holder's business and the holder does not
intend to participate and has no arrangement or understanding with any person to
participate in the distribution of the new notes. Each broker-dealer that
receives new notes for its own account in exchange for old notes, where the old
notes were acquired by the 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 new notes.
See "Plan of Distribution."


                                       32
<PAGE>

     By tendering in the exchange offer, each holder will represent to us that,
among other things:


          o    the new notes acquired pursuant to the exchange offer are being
               obtained in the ordinary course of business of the person
               receiving the new notes;

          o    the holder has no arrangement or understanding with any person to
               participate in the distribution of the new notes; and

          o    the holder acknowledges that if it participates in the exchange
               offer for the purpose of distributing the new 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 new notes and
               cannot rely on the no-action letters referenced above, and (b)
               failure to comply with the requirements in this instance could
               result in the holder incurring liability under the Securities Act
               for which the holder is not indemnified by us. By tendering in
               the exchange offer, each holder represents to us that it is not
               our "affiliate" (as defined in Rule 405 under the Securities
               Act).

CONSEQUENCES OF FAILURE TO EXCHANGE

     As a result of the making of this exchange offer, we generally will have
fulfilled our obligations under the registration rights agreement, and holders
of old notes who do not tender their old notes generally will not have any
further registration rights under the registration rights agreement or
otherwise. Any holder of old notes that does not exchange its old notes for new
notes will continue to hold the old notes and will be entitled to all the
rights, and subject to all the limitations, applicable to the notes thereto
under the indentures, except to the extent that rights or limitations, by their
terms, terminate or cease to have further effectiveness as a result of the
exchange offer.

     Old notes that are not exchanged for new notes pursuant to the exchange
offer will remain restricted securities. Accordingly, the old notes may be
resold only:

          o    to us upon redemption thereof or otherwise;

          o    pursuant to an effective registration statement under the
               Securities Act;

          o    if they 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;

          o    outside the United States to a foreign person pursuant to the
               exemption from the registration requirements of the Securities
               Act provided by Regulation S under the Securities Act; or

          o    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.


                                       33
<PAGE>

     Because the exchange offer is for any and all old notes, the number of old
notes tendered and exchanged in the exchange offer will reduce the principal
amount of old notes outstanding. As a result, the liquidity of any remaining old
notes may be substantially reduced.

OTHER

     Participation in the exchange offer is voluntary, and you should carefully
consider whether to accept the exchange offer. Graham & James LLP, New York, New
York, as our counsel, has passed upon the legality of the new notes. Neither we,
the Owners, nor Navigator Holdings or any of our representatives is making any
representation to any new notes offered in exchange by this prospectus regarding
the legality of an investment by the offeree or purchaser under appropriate
legal investment or similar laws. These laws regulate the nature and extent of
permitted investments in certain securities for certain institutional investors.
You should consult with your own advisors as to legal, tax, business, financial
and related aspects of participation in the exchange offer in light of your own
circumstances.

     We may in the future seek to acquire untendered old notes in open market or
privately negotiated transactions, through subsequent exchange offers or
otherwise. We have no present plans to acquire any old notes that are not
tendered in the exchange offer or to file a registration statement to permit
resales of any untendered old notes.

                                 USE OF PROCEEDS

     The exchange offer is intended to satisfy certain of our obligations under
the registration rights agreement. We will not receive any cash proceeds from
the issuance of the new notes offered by this prospectus. In consideration for
issuing the new notes as contemplated in this prospectus, we will receive in
exchange old notes in like principal amount, the form and terms of which are
substantially the same as the form and terms of the new notes, except as
otherwise described in this prospectus. The old notes surrendered in exchange
for the new notes will be retired and canceled and cannot be reissued.
Accordingly, issuance of the new notes will not result in any increase in our
indebtedness.

     The net proceeds from the offerings of the old notes was loaned to the
Owners to fund the purchase price of the vessels, to pay interest on the old
notes during the construction of the vessels, to obtain the letter of credit and
pay fees thereon during the construction of the vessels and to pay fees and
expenses in connection with the issuance of the old notes and the warrants and
the establishment of the Company.

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

OVERVIEW

     We were formed by Navigator 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 closing date of the
offering of the old notes, neither we nor any of the Owners had any operating
history and all had nominal capitalization.

     Navigator Holdings entered into the contracts to build the vessels, the
Technical Supervision Agreement, the Technical Management Agreement and the
Commercial Management Agreement. Navigator Holdings has assigned to each Owner
the contract to build the 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 date of issuance of the old notes, we:

     o    received the proceeds, net of the Initial Purchasers' discounts and
          commissions and financial advisory fees, from the offerings and lent a
          portion of the net proceeds to the Owners on a joint and several basis
          pursuant to a promissory note (the "Intercompany Note");

     o    paid certain fees and expenses incurred in connection with the
          offerings;

     o    deposited $225.4 million into the Pre-Funding Account and $47.3
          million into the Capitalized Interest Account (earning interest at
          6.785% annual yield); and

     o    entered into the Letter of Credit Reimbursement Agreement.

     Between August 8, 1997 and March 31, 1999, we, on behalf of the Owners,
instructed the collateral agent to make the following payments from the
Pre-Funding Account and Capitalized Interest Account:

     o    $12.2 million to Tractebel Gas Engineering for the construction of the
          gas tanks;

     o    $45.5 million to Jiangnan for the construction of the vessels;

     o    $225,000 for management fees to the Manager;

     o    $937,500 for letter of credit fees to the letter of credit issuer; and


                                       38
<PAGE>

     o    $47.8 million for interest on the notes paid to the noteholders.

OPERATIONS

     Our operations will be limited to:

     o    owning the Owners;

     o    receiving payments under the Intercompany Note;

     o    making payments of interest and principal on the notes; and

     o    fulfilling our obligations under the indentures, the Intercreditor
          Agreement, the Letter of Credit Reimbursement Agreement and the
          registration rights agreement.

     Between the date of issuance of the old notes and the delivery date of each
vessel, the operations of each Owner has consisted and will consist solely of:

     o    entering into commercial arrangements for the future operations of the
          vessels;

     o    managing the construction of the vessels;

     o    paying management fees;

     o    paying installments under the building contracts;

     o    fulfilling its obligations under the Management Agreement; and

     o    fulfilling its obligations under its guarantee.

     On and after the delivery date of each vessel, the operations of each Owner
will consist solely of:

     o    operating, maintaining, insuring and using the vessel and conducting
          activities related thereto;

     o    receiving payments under charters, contracts of affreightment and
          other contracts relating to the employment of its vessel;

     o    receiving proceeds from any sale of its vessel;

     o    paying interest and principal on the Intercompany Note and any other
          permitted indebtedness;

     o    paying management fees;


                                       39
<PAGE>

     o    fulfilling its obligations under the Management Agreement; and

     o    fulfilling its obligation under its guarantee.

CAPITAL RESOURCES AND LIQUIDITY

     Before the contractual delivery date of each vessel, interest on the
principal amount of the notes allocated to the particular vessel 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 the 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 principal
amount of the notes allocated to the 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 investments of certain cash and the proceeds
from any sale of its vessel. In addition, we have obtained a letter of credit in
a total amount of $50.0 million. Under the letter of credit, $45.5 million is
available as a liquidity support to fund payments of interest to the noteholders
under certain circumstances, and $4.5 million is available as a working capital
facility for certain amounts payable by the Owners. Under certain circumstances,
interest on the new Second Priority Notes and the untendered old Second Priority
Notes may be paid through the issuance of additional new Second Priority Notes.
See "Description of the New Notes--Terms of the New Notes--Second Priority
Notes." We do not have and do not expect to have in the future any other source
of capital for payment of our debt service obligations under the notes. See
"Risk Factors--You may suffer if our business fails because we, the Owners and
Navigator Holdings exist solely for the purpose of owning, operating, and/or
guaranteeing obligations in connection with the vessels and the notes."

     The following table indicates the amount of the gross proceeds received by
each of the Owners from the offering of the old notes loaned to them under the
Intercompany Note.

                              GAS CARRIER INDUSTRY

OVERVIEW

     Gas carriers transport three main types of liquefied gases:

     o    petrochemical gases such as ethylene, propylene, vinyl chloride
          monomer ("VCM"), butadiene and crude C4;

     o    liquefied petroleum gas ("LPG") products such as ethane, propane and
          butane; and

     o    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 liquefied for seaborne transportation in gas
carriers.

     There are several types of gas carriers which use different techniques to
liquefy and transport cargoes, including:

     o    fully-pressurized vessels that rely solely upon high pressure to
          liquefy gases;

     o    fully-refrigerated vessels that have the ability to maintain cargo in
          a liquefied state by cooling gases to a temperature of -48(degrees)C;
          and

     o    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 cubic meter ("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(degrees)C, and ethane, which
requires cooling temperatures to -82(degrees)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 the 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 new
vessels being delivered, the loss of vessels and the scrapping of older vessels.

     0 - 7,000 CBM. Vessels in this class are primarily 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.

     7,001 - 10,000 CBM. 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 - 22,000 CBM. Vessels in this class 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.

     22,001 - 50,000 CBM. 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. 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.

     Larger than 60,000 CBM. Vessels in this class are fully-refrigerated and
carry LPG on long-hauls worldwide.

     The eleven vessels in the world ethylene-capable fleet that are being built
include the vessels the Owners are building.

     Several factors in the gas carrier industry limit supply growth:

     o    the importance of having a sufficient size fleet to engage in
          efficient triangular trading;

     o    the operational and technical expertise required to operate gas
          carriers; and

     o    the limited number of shipyards which have the expertise required to
          build gas carriers which incorporate sophisticated gas plant systems.

DEMAND FOR GAS CARRIERS

     The transportation of petrochemical gases is a 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 cargoes and their
trading patterns that the Company is targeting:

     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 anti-freeze,
resins and fibers. Worldwide seaborne trade of ethylene rose at a compound
annual growth rate of 5.4% from 2.0 million tons in 1990 to 3.0 million tons in
1998. Historically, the exporting regions of ethylene have been the Middle East,
Europe and Latin America. 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 expected to
increase their imports.

     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 1998, worldwide
seaborne trade in propylene increased at a compound annual growth rate of 1.9%
from 1.5 to 1.8 million tons. 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. Worldwide
seaborne trade of VCM rose at a compound annual growth rate of 4.5% from 1.0
million tonnes in 1990 to 1.4 million tonnes in 1998. The United States is the
primary exporter of VCM and Southeast Asia and Latin America are the principal
importers.


                                       46
<PAGE>

     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. Synthetic 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. Worldwide seaborne trade of butadiene
rose at a compound annual growth rate of 2.6% from 555,000 tons in 1990 to
682,000 tons in 1998. 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.

     Liquefied Petroleum Gas (LPG). LPG is produced as a by-product either from
the production of natural gas or the refining of crude oil. The primary uses of
LPG are as fuel for transportation, for 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 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 46.6 million tons in 1998, which represents a 5.0%
compound annual growth from 1990. We view the transportation of ethane, a
feedstock for petrochemical products that requires cooling to -82(degree)C for
liquefication, as an emerging opportunity for the vessels the Owners are
building.

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 and 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 1998 to 2001:

     Since the seaborne trade of petrochemical gases began in the early 1980's,
land-based terminal storage facilities have grown steadily, providing access to
larger, more efficient vessels with increased economies of scale. For example,
the first generation of land-based ethylene terminals had a storage capacity of
8,000-15,000 cbm. By the late 1980's, the maximum land-based 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. We believe
that this trend of increasingly larger land-based storage facilities will
support the


                                       48
<PAGE>

transport of larger volumes of petrochemical gases resulting in greater demand
for the vessels the Owners are building.

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
liquefied 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 specific 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.

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 a few large and experienced operators. There is
currently one significant participant in the ethylene carrier segment with
vessels over 10,000 cbm. The largest owner is Bergesen d.y. ASA. Bergesen
controls the Igloo pool (a cooperative marketing venture among several owners)
of 18 vessels ranging in size from 8,000 cbm to 12,000 cbm, most of which were
built in the 1980's.

     In the semi-refrigerated, non-ethylene carrier market, Handygas, controlled
by Bergesen, and A. P. Moller 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. A. P. Moller's fleet of 21
semi-refrigerated vessels is newer and ranges in size from 15,000 cbm to 21,000
cbm.

                                    BUSINESS

GENERAL

     We, the Owners and Navigator Holdings were each 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 Owner's
vessels. Each vessel will have four separate gas cargo tanks, segregated pumping
and piping systems and two separate deck tanks, allowing each vessel to carry up
to three separate temperature controlled cargoes simultaneously.

     When built, 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 vessels' capabilities will
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.

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 48.7 million tonnes is expected to be
on line by the beginning of the next decade, representing a 30.2% increase over
global capacity at the end of 1997. These expanded and new facilities are
typically incorporating large-scale storage terminals which include multiple
tanks capable of handling many different petrochemical products. We believe 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.


                                       50
<PAGE>

AN ATTRACTIVE MARKET FOR SEABORNE TRADE OF ETHYLENE

     We believe that the market for seaborne transportation of ethylene, the key
building block for plastics and a feedstock for other petrochemicals, is
particularly attractive. World ethylene production capacity has doubled over the
past 15 years to a total capacity of approximately 80 million tonnes in 1997.
This trend is expected to continue with additional production capacity of
approximately 30 million tonnes expected by the beginning of the next decade.
Due to its low temperature requirement of -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 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 temperature requirement of -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 code certification, Chemical Distribution
Industry certification and inspection certification by major customers, we
believe 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. Given these entry barriers and the unique capabilities of the
Owners' vessels, we believe that we will have a competitive advantage over other
industry participants. See "--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 strategy is to take advantage of the demand for seaborne
transportation of petrochemical gases and LPG resulting from the worldwide
expansion in the


                                       51
<PAGE>

production, use and trade of petroleum by-products. The Company's fleet will
supply transportation services to existing customers of some of the stockholders
of Navigator 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. These contracts are expected to be from one
to five years in length and would provide the vessels with a high level of
continuous employment. We also intend 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. MarLink is a leading commercial manager of vessels in the petrochemical
gas market.

     The Company has entered into a letter of intent with a major petrochemical
supplier to utilize the vessels. Under the letter of intent, the parties intend
to enter into an agreement covering the worldwide transportation of
petrochemical gas for a minimum period of five years. At the specified maximum
quantities, the agreement would provide for the full utilization of between two
to four of the Owners' vessels depending on the loading and discharge ports
designated by the charterer.

     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 us
to maximize the proportion of the 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, we also believe
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 to transport up to
three segregated temperature controlled cargoes simultaneously. We believe that
these larger, multiple-tank vessels will provide the Company with 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. We have chosen the builders of the vessels because of
their previous experience in the building of gas carriers with Tractebel Gas
Engineering, a leading engineering firm in the production of gas plants. See
"--The Vessels" and "--The Builders and Tractebel Gas Engineering."

     Maximize Vessel Utilization. We believe that our fleet size of five
vessels, each with four tanks and the ability to carry up to three segregated
temperature controlled cargoes, will allow our fleet to adopt triangular trade
patterns which minimize ballast trips. In addition, the vessels' ability to
carry up to four cargoes simultaneously will give us the potential to service up
to 15 charterers at any one time. We believe that the size of the vessels will
also be attractive


                                       52
<PAGE>

to charterers with substantial long-haul transport requirements. Our fleet size
and configuration will provide the operational flexibility necessary to meet the
logistical demands of managing complex trading patterns.

THE VESSELS

     The Owners' vessels will be state-of-the-art gas carriers. We believe that
the size and configuration of the Owner's vessels, as well as the features
incorporated therein, will make them more attractive to charterers than other
vessels. As a result, we expect 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, resulting in higher earnings for each vessel.

     The Owners' vessels will be semi-refrigerated, combining refrigeration and
pressurization to maintain their cargoes in a liquefied 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 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 the loading of products and limits the number of
terminals which can be efficiently serviced by the vessels.

     The nitrogen generator and deck tanks on each of the vessels will allow us
to prepare a vessel's 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 the operations
and the associated costs.

     The vessels will sail under the Isle of Man flag, with a certification from
Germanischer Lloyd. 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 Germanischer Lloyd and shall be
distinguished in the record by the symbol "GL + 100 A5 E Liquefied Gas Carrier
Type 2G + MC, E, AUT, INERT" as per specification. For the Owner to accept its
vessel, the vessel must comply with the laws, rules, regulations,
recommendations and requirements as set out in the specifications attached to
the related building contract.

Technical Supervision Agreement

     GEBAB was engaged by the Owners to supervise the construction of the
vessels during the pre-delivery period. GEBAB, Navigator Holdings, on behalf of
the Owners, and the builders entered into an Agreement on Contract for Technical
Matters (the "Technical Supervision Agreement"), dated as of February 28, 1997,
pursuant to which each Owner has appointed GEBAB to act as the Owner's technical
representative for technical matters related to the construction of its vessel.
On August 7, 1997 Navigator Holdings assigned its rights under


                                       54
<PAGE>

the Technical Supervision Agreement to the Manager on behalf of the Owners. As
of October 19, 1998, GEBAB assigned by novation its responsibilities under the
Technical Supervision Agreement to its affiliate, Martime Asia. Martime Asia, in
coordination with Germanischer Lloyd, will monitor the construction of each
vessel.

     Pursuant to the Technical Supervision Agreement, Martime Asia will, among
other things, examine all hull and engineering plans submitted by the builders
to ensure that they comply with the terms of the building contracts, monitor the
construction of the vessels to ensure compliance with the terms of the building
contracts and the requirements of Germanischer Lloyd, render monthly progress
reports, advise the Owners of any modifications or improvements which may
improve the vessels or reduce operating costs and oversee any work performed in
drydock prior to the delivery of each vessel.

THE BUILDERS AND TRACTEBEL GAS ENGINEERING

     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 China Shipbuilding, 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
dead weight tonne ("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 rockets and satellites 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 Tractebel Gas Engineering and in 1998
completed 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 semi-refrigerated
ethylene carriers; a 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 five 1,021
TEU fast-speed feeder container vessels.

     Tractebel Gas Engineering is an indirect subsidiary of Tractebel, S.A., a
major Belgian public company engaged in the utility and engineering industries.
Tractebel Gas Engineering is a world leader in the engineering, design and
construction of gas storage and


                                       55

transportation plants and equipment. It also manufactures port facilities for
the off-loading and receiving of liquefied gases, gas liquefication and handling
systems, chemical and gas plants for installation on carriers, storage
facilities for liquefied 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. Tractebel Gas
Engineering is a leading provider of turnkey operations. Tractebel Gas
Engineering will design the complex gas plants utilized on the Owners' vessels.
Tractebel Gas Engineering will also supervise the construction and erection of
the vessels' gas plants through its permanent office in Shanghai. Since 1980,
Tractebel Gas Engineering has been involved in the installation of gas plants
for 41 gas carriers, 23 of which are ethylene-capable. Tractebel Gas Engineering
will act as a subcontractor to Jiangnan under each building contract for a
vessel and will be responsible for supplying materials for construction of the
gas plant and supervising its installation.

     Jiangnan and Tractebel Gas Engineering have worked together on the
construction of the following gas carriers and components:

BUILDING CONTRACTS

Specifications

     Each vessel will be constructed pursuant to the terms and specifications of
the building contracts. The vessels are being built under the building contracts
between the builders and Navigator Holdings, each dated as of February 4, 1997,
as amended and restated as of June 26, 1997 and as further amended as of August
1, 1997, and assigned by Navigator Holdings to the Owners on or before the date
of initial issuance of the old notes.

Contractual Delivery Date

     The contractual delivery dates of the vessels will be staggered as follows:

              Navigator Mars                 --       August 1, 1999
              Navigator Venus                --       November 1, 1999
              Navigator Saturn               --       March 1, 2000
              Navigator Pluto                --       June 1, 2000
              Navigator Neptune              --       September 1, 2000

     If a change in the rules or regulations of Germanischer Lloyd causes a
period of delay of up to 12 days in the delivery of a vessel, the contractual
delivery date will be extended by that period.

     Vessel construction is proceeding slightly behind the original schedule for
the first two vessels and slightly ahead for the last three vessels, with the
first vessel scheduled for delivery the end of August 1999 and the entire fleet
to be delivered by the end of July 2000.

PURCHASE PRICE

     The purchase price for each vessel will be approximately $50.2 million. The
following table sets forth the scheduled amounts and timing of the payments to
the builders under the building contracts, except that the builders have
directed the Owners to make the payment due on September 1, 1997 directly to

(a) Assuming delivery of the vessel occurs on its contractual delivery date.
Under various addenda to the specifications the Owners have agreed to pay
Jiangnan and Tractebel Gas Engineering an additional $245,000 per vessel,
payable on the delivery date of each vessel.

(b) This payment shall be payable to the builders for a vessel only if and when
the collateral agent has received evidence of delivery pursuant to the building
contract for each other vessel having a contractual delivery date prior to the
contractual delivery date of such vessel.

(c) May not total due to rounding.

     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 the vessel is
delivered earlier than its contractual delivery date. In addition, in the event
of certain delays in the delivery of a vessel or the failure of a 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 for 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, 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 only 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 of them.

     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 the
vessel in an amount equal to $11,000 per day for the first 90 days of delay
beyond the Permissible Delay Period 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. These liquidated
damages are expected to be sufficient to pay the interest on the principal
amount of the notes allocated to each vessel. In the event the builders fail to
make timely payment of these liquidated damages, each affected Owner may (1)
waive its right to payment and elect instead to receive a further reduction in
the final installment of the purchase price (in addition to any reduction during
the First Delay Period) equal to the amount of the liquidated damages waived or
(2) rescind the related building contract and demand payment of the specified
Refund Amount for the vessel. 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


                                       58
<PAGE>

demand the payment at any later date of 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 the vessel in compliance with specifications for 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 for speed, fuel
consumption, deadweight and cargo tank capacity. The events of default relating
to non-delivery of a vessel are:

     o    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 the liquidated damages;
          and

     o    the failure to deliver the vessel by March 31, 2001.

The Owner may also rescind a building contract if its vessel has any of the
following deficiencies:

     o    its speed is one knot or more below the guaranteed speed of 16.5
          knots;

     o    its fuel consumption is 8.0% or greater than the guaranteed fuel
          consumption set forth in the vessel's specifications;

     o    its deadweight is more than 800 tons below the guaranteed deadweight
          of 22,800 tons; and

     o    its cargo tank capacity is more than 400 cbm below the guaranteed
          cargo tank capacity of 22,000 cbm.

A building contract will be automatically terminated if, prior to the delivery
date;

     o    a vessel is seized by the Chinese government;

     o    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 the particular vessel; or

     o    a total loss occurs with respect to a vessel.

In addition to the circumstances described in the preceding sentence, the
builders must not elect to continue performing under the building contract.


                                       59
<PAGE>

     Under the cross-default provisions of the building contracts, in the event
a building contract is rescinded by an Owner or automatically terminated, any
other Owner that has not accepted delivery of its vessel will be deemed to have
also, rescinded its building contract.

Mandatory Redemption of the Notes and the Refund Amount

     In the event a building contract is rescinded or automatically terminated,
we are required, under the terms of the indentures, to redeem the principal
amount of the notes allocated to the relevant vessels, and the builders must,
under the building contracts, pay the affected Owner a specified refund amount.
The refund amount together with the amounts held in the Pre-Funding Account and
the Capitalized Interest Account for the building contracts 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. If the builders delay the
payment of the refund amount, 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 the builder makes payment in full of the refund amount plus any
refund interest on the refund amount.

Gas Trials

     Prior to the delivery date for a vessel, 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 will be made by the builders. The tests will be repeated until the
results are deemed by Germanischer Lloyd to be in conformity with the building
contract and the specifications for the vessel.

     After the delivery date, the Owner will, at its own cost and expense, carry
out an additional gas trial in accordance with the trial program furnished by
Tractebel Gas Engineering. The Owners must carry out the gas trials within 45
days after the delivery dates subject to certain exceptions. Germanischer Lloyd
will certify each gas trial. If the gas plant is not in conformity with the
building contract and the specifications for the vessel, the builders must
remedy the non-conformity to the satisfaction of the Owner, Germanischer Lloyd
and any other relevant authority. If the 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


                                       60
<PAGE>

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 for the vessel.

BUILDING CONTRACT GUARANTEES AND PERFORMANCE BONDS

     The Export-Import Bank of China, the building contract guarantor, has
delivered an irrevocable building contract guarantee with respect to each vessel
and an irrevocable builders performance bond relating to all five vessels, each
on behalf of the builders. Generale de Banque has delivered an irrevocable
performance bond on behalf of Tractebel Gas Engineering, 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 interest on the refund amount. 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 the building contract is rescinded by the affected
Owner or automatically terminated. The performance bond issued by the
Export-Import Bank of China covers an aggregate amount of up to approximately
$32.5 million for all five vessels and the performance bond issued by Generale
de Banque covers an aggregate amount of up to approximately $16.2 million for
all five vessels. The availability of the performance bond issued by Generale de
Banque, however, is conditioned upon the payment by the Export Import Bank of
China to the Owners of the maximum amount of $32.5 million guaranteed under its
performance bond.

     Pursuant to the terms and conditions of the Intercreditor Agreement, the
collateral agent will draw under the performance bonds an amount equal to the
Rescission Amount, calculated as of the date on which the new notes and any
untendered old notes are scheduled for redemption, minus the sum of (1) the
amounts held in the Pre-Funding Account and in the Capitalized Interest Account
and (2) the amount payable under the applicable building contract guarantees.

     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 closing date of the
issuance of the old notes with the net proceeds of the offerings. Each building
contract guarantee will expire with respect to the related building contract
upon the earliest of (1) the receipt by the Owner of the guaranteed amount, (2)
the confirmation to the building contract guarantor of acceptance of the related
vessel and (3) May 1, 2001. Each of the performance bonds will expire upon the
earliest of (1) the receipt by any of the Owners of any payment thereunder, (2)
the receipt of confirmation by the applicable performance bond guarantor of the
acceptance of all remaining vessels and (3) May 1, 2001.

     The Export-Import Bank of China is owned by the government of the People's
Republic of China and its long-term debt is rated Baal by Moody's and BBB+ by
Standard and Poor's. The Long-term debt of Generale de Banque is rated 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 Owners' 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 employment as dictated by the overall market for gas transport. On or
prior to the date of the issuance of the old notes, we, Navigator Holdings and
each of the Owners engaged the Manager to manage our 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 or any of its
affiliates' 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. Although the Owners are new entrants
with little experience in the gas carrier industry, they expect to compete
successfully with more established companies because their commercial technical
manager - Martime Asia - has extensive experience in the field.

     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. This kind of 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 Company has entered into a letter of intent with a major petrochemical
supplier to utilize the vessels. Under the letter of intent, the parties intend
to enter into an agreement covering the worldwide transportation of
petrochemical gas for a minimum period of five years. At the specified maximum
quantities, the agreement would provide for the full utilization of between two
to four of the Owners' vessels depending on the loading and discharge ports
designated by the charterer.

     The Manager is implementing and will implement a marketing strategy on
behalf of the Owners through the marketing efforts of its principal employees.
In addition, Marlink through its Commercial Management Agreement with the
Owners, which is described below, will market the vessels on behalf of the
Owners. The Owners intend to supplement the marketing efforts of the Manager and
Marlink by maintaining a non-exclusive brokerage relationship with Xenon
Shipping AS.

     We have preliminarily identified Chevron Products Company, Pequiven, Norsk
Hydro, Enichem, PMI, Dow Chemicals, Mitsui USA, and Sunkyong America, Inc.,
among


                                       62
<PAGE>

others, as potential customers in the petrochemical market. We have 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 us 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.

Commercial Management Agreement

     Navigator Holdings on behalf of the Owners and GEBAB entered into a Master
Commercial Marketing and Services Agreement (the "Commercial Management
Agreement"), dated as of February 28, 1997, under which GEBAB agreed to
commercially manage the vessels. On August 7, 1997, Navigator Holdings assigned
its rights under the Commercial Management Agreement to the Manager on behalf of
the Owners. As of October 19, 1998, GEBAB assigned its obligations under this
agreement to its affiliate, MarLink, through a novation agreement. As the
assignee of GEBAB, upon the completion and delivery of the particular vessel to
its Owners, Marlink will solicit cargo to be transported by the vessels.
Marlink'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 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.

     MarLink will arrange for all income earned with respect to each vessel to
be paid directly into a lock-box account to be held by the collateral agent.
Pursuant to the Commercial Management Agreement, a management fee of 2.0% of
gross revenues from operations received in a given calendar quarter is payable
quarterly by the Manager from the operating account on the 16th day following
the end of each calendar quarter which shall end on the last day of March, June,
September and December. MarLink will deliver a quarterly statement reflecting
the gross operating revenues of the vessels received in the lock-box 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 is due within 15 days after the end of each calendar quarter. Each
month, the Owners will be provided with an estimate of employment-related
expenses. Actual expenses will be paid directly by the Owners upon the
presentation of invoices to the Manager from amounts held in the operating
account.

     The Commercial Management Agreement with respect to each vessel has a term
of three years commencing on the delivery to the related Owner of the vessel,
and it will continue after the end of the three-year term indefinitely until
terminated by MarLink or any Owner at any time by giving six months written
notice to MarLink or the Owner, respectively.

OPERATIONS

     The Manager intends to implement the Owners' operating strategy by
administering the Technical Management Agreement between Martime Asia and the
Owners.


                                       63
<PAGE>

Technical Management Agreement

     GEBAB and each of its affiliated companies and Navigator Holdings on behalf
of the Owners entered into a Baltic and International Maritime Council (BIMCO)
Standard Ship Management Agreement (the "Technical Management Agreement"), dated
as of February 28, 1997, under which Navigator Holdings, as predecessor to the
Owners, appointed GEBAB and each of its affiliated companies to act as technical
manager of the vessels. On July 31, 1997, Navigator Holdings assigned its rights
under the Technical Management Agreement to the Manager on behalf of the Owners.
As of October 19, 1998, GEBAB assigned its obligations under this agreement to
its affiliate, Martime Asia through a novation agreement. Under the Technical
Management Agreement, Martime Asia will provide for and supervise the crew of
each vessel, supervise and maintain the technical management of each vessel,
arrange for all insurance 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.

     Martime Asia will present an annual budget three months before the end of
each calendar year. The projected budget for 1999, the year the first vessel is
expected to be delivered and become operational, is an average of $190,000 per
month, which amount is expected to be sufficient to cover crew cost and basic
operating expenses, including insurance cover, deck equipment, cargo plant,
engine maintenance, 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 of the budgeted year, Martime Asia 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.

     The Technical Management Agreement provides for a management fee of 2.0% of
gross operating revenues for the first six years after delivery of a vessel and
2.5% thereafter. The fee will be payable by the Owners from the operating
account quarterly in advance on the first day of the calendar quarter based on a
pre-approved budget submitted by Martime Asia. 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 the calendar quarter will be
reflected in the budgeted monthly management fee payable on the first day of the
second month immediately following the end of any calendar quarter.

     The Technical Management Agreement with respect to each vessel has a term
of three years commencing on the delivery to each Owner of its vessel, and it
will continue after the end of the three-year term indefinitely until
termination by Martime Asia or any Owner at any time by giving 90 days written
notice to MarLink or the Owner, respectively.

INSPECTION

Chemical Distribution Institute

     The Chemical Distribution Institute 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


                                       64
<PAGE>

Chemicals and Mobil Chemical Company. The Chemical Distribution Institute has
set common vessel inspection criteria for the safe transportation of hazardous
cargo at sea, according to the standards of all individual member companies. The
Chemical Distribution Institute 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. The
Chemical Distribution Institute is fully-implemented in Europe and the Americas
and is in the process of being implemented in Asia. We and the Owners intend to
fully meet all the Chemical Distribution Institute code requirements and receive
certification.

International Safety Management

     International Safety Management publishes a code (the "International Safety
Management Code") which sets forth standards applicable for internationally
acceptable procedures in safe contemporary ship management. The International
Safety Management Code has been endorsed by the IMO and plays an important role
in international ship management. Entities that do not obtain certification
under the International Safety Management Code have increasing difficulties in
marketing their services. Certification under the International Safety
Management Code is carried out by classification societies acting as auditors
and must be complied with by 1999. We intend to fully meet all International
Safety Management Code requirements. In addition, Martime Asia received both
International Safety Management and ISO certifications in 1999.

ENVIRONMENTAL REGULATIONS

     Our business and operations 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 these conventions, laws and regulations are often revised,
and have become increasingly stringent, we cannot predict the ultimate costs of
compliance with any 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 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: (1) removal
costs or remedial action taken by the United States or a local government; (2)
other necessary costs of response incurred by any other person consistent with
the National Contingency Plan (the primary guidance document for CERCLA response
actions); (3) damages for injury to, destruction of, or loss of natural
resources, including the cost of assessing the injury, destruction, or loss; and
(4) the costs of any health assessment or studies permitted under CERCLA. Since
the vessels may carry substances as cargo which are considered hazardous
substances under CERCLA, a discharge or threat of discharge of the cargo could
result in


                                       65
<PAGE>

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 ton or $5,000,000 for vessels that carry hazardous
substances as cargoes. These limits will not apply if: (1) 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 (2) 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. 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 liability limit supported by insurance, a
surety bond, self-insurance or a guarantee. Without these 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. 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, us and holders of the notes.

Oil Pollution Act of 1990

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

     Liability imposed under the Oil Pollution Act 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. A spill could include the
discharge of bunkers from the vessels.


                                       66
<PAGE>

Subject to statutory qualifications, a sole fault third party may be also be a
responsible party under the Oil Pollution Act. For example, a vessel could cause
another vessel to suffer a discharge of oil. Other damages recoverable under the
Oil Pollution Act include:

     o    natural resource damages and the costs of assessment;

     o    real and personal property damage;

     o    net loss of taxes, royalties, rent, fees, and other lost government
          revenues;

     o    lost profits or impairment of earning capacity due to property or
          natural resource damage;

     o    net cost of public services necessitated by a spill response, such as
          protection from fire, safety or health hazards; and

     o    loss of subsistence use of natural resources.

     A responsible party's limit of liability under the Oil Pollution Act is the
greater of $1,200 per gross ton 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. The Oil Pollution Act does not by its terms impose liability
on lenders or the holders of mortgages on vessels; however, there is no specific
exclusion for these entities under the Oil Pollution Act. 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 an event of default under the ship mortgages, such persons or
entities may be subject to liability under the Oil Pollution Act. 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.

     The Oil Pollution Act, like CERCLA, requires owners and operators of all
vessels, whether or not the 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 the Oil Pollution Act. 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. These response plans must, among other things:

     o    identify and ensure, through contract or other approved means, the
          availability of necessary private response resources to respond to a
          "worst case" discharge;


                                       67
<PAGE>

     o    describe crew training and drills;

     o    identify a qualified individual with full authority to implement
          removal actions; and

     o    describe mitigation and response actions. The Owners will ensure that
          the vessels have response plans approved by the Coast Guard.

     The Oil Pollution Act 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
legislation have not yet issued implementing regulations defining tanker owners'
responsibilities under these laws. Additionally, under the Oil Pollution Act 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.

     The Oil Pollution Act expressly provides that individual states are
entitled to enforce their own pollution liability laws, even if inconsistent
with or imposing greater liability than the Oil Pollution Act. There is no
uniform scheme among the states. Some states have the Oil Pollution Act-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 state regulations, and the liabilities imposed thereunder,
may have a material adverse effect on the business and the operations of the
Owners and therefore us, and any charterer of the vessels.

International Maritime Organization

     The IMO, a specialized agency organized in 1958 by the United Nations in
which over 100 countries 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 member states.

     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 was open
for signature until October 1, 1997.

     As of June 1, 1999, there were eight signatories to the HNS Convention,
none of whom have ratified the 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.


                                       68
<PAGE>

     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
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.
There are two tiers of liability under the HNS Convention. The first tier 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: (1) for vessels less than 2,000 gross tons, the limit of
liability is 10 million Special Drawing Rights ("SDRs"). A SDR is defined by the
International Monetary Fund on the basis of a basket of currencies. The exchange
rate in effect on May 28, 1999 for the dollar equivalent of the SDR was
approximately 1.34; (2) for vessels greater than 2,000 gross tons but less than
50,000 gross tons the limit of liability allows an additional limit of 1,500
SDRs per ton above 2,000; and (3) for vessels with a gross tonnage in excess of
50,000 the limit of liability allows an additional 360 SDRs per ton up to a
maximum of 100 million SDRs. For example, at $1.39 per SDR, a 100,000 gross ton
vessel would have 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 the damage, or recklessly and with
knowledge that the damage would probably result.

     The HNS Fund will be composed of several accounts. There will be a separate
account for: (1) liquefied natural gas ("LNG"); (2) LPG; and (3) 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 the
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 sent
an invoice 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 CLC Convention. 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 tons 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.
For example, 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


                                       69
<PAGE>

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
the 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, those regulations might have on the operation of the
vessels.

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

     Cambridge Gas, GEBAB, Xenon Shipping and their affiliates, the "Designated
Owners," have agreed not to dispose of their shares of stock in Navigator
Holdings if any notes are outstanding, except that they may sell a portion of
their stock, if after the sale, the stock held by the Designated Owners, either
directly or indirectly, represents more than 50% of the total voting power of
the voting stock of Navigator Holdings and more than 50% of the equity interests
in Navigator Holdings.

STOCKHOLDERS AGREEMENT

     Navigator 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. Cambridge Gas
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. Tractebel Gas Engineering has agreed not to dispose of its stock
in Navigator Holdings except to an affiliate of Tractebel Gas Engineering prior
to the expiration of the warranty period of the last vessel to be delivered. The
other stockholders have the right, in the event Cambridge Gas sells all or any
portion of the stock it holds in Navigator Holdings, to require Cambridge Gas to
purchase a proportionate amount of Navigator Holdings stock from the other
stockholders as the number of shares it is selling. The agreement contains
provisions which prevent the Designated Owners from reducing their aggregate
interest in Navigator Holdings to less than a majority interest.

                              CERTAIN TRANSACTIONS

Commercial Management." In addition, the Manager will oversee during the
pre-delivery period all aspects of the vessels' construction on behalf of the

million for marketing and other services in connection with the financing of the
Owners' vessels during their construction, (2) Xenon Shipping AS received $1.0
million to market the vessels during


                                       78
<PAGE>

their construction and (3) Xenon Shipping, Inc. received a brokerage commission
from the builders in the amount of $9.3 million. On September 1, 1997, Tractebel
Gas Engineering received the second installment of the purchase price in the
amount of $2.4 million per vessel payable under the building contracts. Upon
delivery of each vessel, Tractebel Gas Engineering will receive $100,000 per
vessel for modifications made to the gas plants within the vessels, as amended
to the building contracts.

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 or
conditional sale contracts with UK Lessors under which the UK Lessors will
initially pay an amount equal to substantially all of the purchase price for
each of the related vessels and which grants the UK Lessors a right of
possession in respect of the vessels. Each hire purchase agreement or
conditional sales contract will provide that the related Owner will, unless the
related UK Lessor fails to exercise its option in the case of an hire purchase
agreement or otherwise elects in the case of a conditional sales contract, 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 the vessel or following any
early termination of the related bareboat lease at which time the remainder of
the purchase price for the 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 in 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 the rights, pursuant to an intercreditor or coordination agreement. The
Owners and the collateral agent will acknowledge to the related UK Lessors that
they will (1) not vary provisions of the related mortgages relating to certain
rights as to the disposition of insurance proceeds and (2) give the UK Lessors
notice of any defaults under the mortgages and the right to cure such defaults,
except that the 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 for the 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
the Defeasance Bank will, in consideration of such payment, assume, up to
specified limits of liability, the payment obligations of the Owner under the
related bareboat lease. To the extent that the payment obligations under a
bareboat lease are assumed by the Defeasance Bank, the related Owner will be
released from those obligations; except that each Owner will remain liable under
its bareboat lease for payment obligations in excess of the obligations that are
defeased.

     It is anticipated that the vessels will be chartered by the Owners to a
shipping company or a subsidiary of Navigator Holdings pursuant to either
bareboat or time charters. It is a requirement of UK tax law that while the
vessels are leased by UK Lessors the leasing arrangements must continue for a
period of 10 years and each lessee must be a company which (1) is liable for UK
corporate tax in respect of its profits from the related vessel and (2) uses the


                                       79
<PAGE>

vessel for the purposes of that company's non-leasing trade or charters the
particular vessel in the manner that satisfies 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 rating agency
then rating the notes must confirm to the trustees in writing that entering into
the UK Lease will not result in a ratings decline with respect to the notes.

                          DESCRIPTION OF THE NEW NOTES

GENERAL

     The new First Priority Notes will be issued, and the old First Priority
Notes were issued, pursuant to an indenture, dated as of August 1, 1997 (the
"First Priority Indenture"), among us, as issuer, the Owners and United States
Trust Company of New York, as First Priority Trustee. The new Second Priority
Notes will be issued, and the old Second Priority Notes were issued, pursuant to
an indenture, dated as of August 1, 1997 (the "Second Priority Indenture"),
among us, as issuer, the Owners and The Chase Manhattan Bank, as Second Priority
Trustee. The First Priority Indenture and the Second Priority Indenture are
collectively referred to herein as the "indentures," and the First Priority
Trustee and the Second Priority Trustee are collectively referred to herein as
the "trustees." Navigator Gas Transport, the Owners, Navigator Holdings, the
trustees, the issuer of the letter of credit and United States Trust Company of
New York, as collateral agent, are all parties to a collateral agency and
Intercreditor Agreement, dated as of August 1, 1997. Copies of the indentures,
the Intercreditor Agreement and the other Security Agreements will be available
as set forth under "Where You Can Find More Information." The following summary
of the material provisions of the notes, the indentures and the Security
Agreements does not purport to be complete and is subject to, and is qualified
in its entirety by reference to, all provisions of the notes, the indentures and
the Security Agreements, including the definitions of terms used therein and
those terms made a part thereof by the Trust Indenture Act of 1939, as amended.
For more complete information, you should obtain and review these documents.

UNITS AND WARRANTS

     The old Second Priority Notes were issued in units together with warrants
entitling the holder to purchase shares of common stock of Navigator Holdings.
Following the exchange offer the new Second Priority Notes and the warrants will
trade separately. Each unit consists of one Second Priority Note and 7.66
warrants entitling the warrant holder to purchase one share of common stock per
warrant at an exercise price of $.01 per share, subject to adjustment.

EXCHANGE

     The new notes have been registered under the Securities Act and,
accordingly, will not be subject to certain restrictions on transfer applicable
to the old notes. The new First Priority Notes have terms and conditions
identical in all material respects to those of the old First Priority Notes, and
the new Second Priority Notes have terms and conditions identical in all
material respects to those of the old Second Priority Notes, except that the new
notes are


                                       80
<PAGE>

registered under the Securities Act, and the old notes are subject to certain
restrictions on transfer and are entitled to the benefit of the registration
rights agreement. Accordingly, unless specifically stated to the contrary, the
following description of the new notes applies equally to the old notes and the
new notes. The new First Priority Notes and the old First Priority Notes will be
treated as one series for purposes of the First Priority Indenture, and the new
Second Priority Notes and the old Second Priority Notes will be treated as one
series for purposes of the Second Priority Indenture. The statements under this
section relating to the old notes, the new notes and the indentures are
summaries of the material terms, but do not purport to be a complete
description, of the indentures, the old notes or the new notes.

TERMS OF THE NEW NOTES

     Interest on the new notes will be computed on the basis of a 360-day year
comprised of twelve 30-day months. Interest on overdue principal, and, to the
extent permitted by law, on overdue installments of interest will accrue at 1%
per annum in excess of the stated rate for each series of notes. The new notes
will be issued only in fully registered form, without coupons, in minimum
denominations of $100,000 and integral multiples of $1,000 in excess thereof.
The new notes may be presented for registration of transfer and exchange at the
offices of the applicable registrar. Initially, the trustee under an indenture
will act as paying agent and registrar with respect to the new notes of the
related series.

First Priority Notes

     The new First Priority Notes and any untendered old First Priority Notes
will be secured obligations of ours will be limited to an aggregate principal
amount of $217,000,000 and will mature on June 30, 2007. The new First Priority
Notes and any untendered old First Priority Notes are guaranteed jointly and
severally by the Owners. See "--Guarantees." The new First Priority Notes and
any untendered old First Priority Notes and the guarantees will be secured by
the collateral and will have the benefit of the letter of credit. See
"--Security."

     The new First Priority Notes and any untendered old First Priority Notes
will bear interest at a rate of 10 1/2% per annum from the date of initial
issuance of the old notes until the principal of the old notes is paid or made
available for payment. Interest on the new notes will be payable semi-annually
on June 30 and December 31 of each year, commencing December 31, 1999 to the
person in whose name the relevant new First Priority Note or the untendered old
First Priority Note is registered at the close of business on the preceding June
15 or December 15, as the case may be. The exchange of old notes for new notes
will not cause any interruption in the payment of interest.

Second Priority Notes

     The new Second Priority Notes and any untendered old Second Priority Notes
will be secured obligations of ours limited to an aggregate principal amount of
$87,000,000, plus up to $20.9 million of additional Second Priority Notes that
may be issued instead of paying cash interest as described below, and will
mature on June 30, 2007. The new Second Priority Notes and any untendered old
Second Priority Notes are guaranteed jointly and severally by the Owners. See
"--Guarantees." The new Second Priority Notes and any untendered old Second


                                       81
<PAGE>

Priority Notes and the guarantees will be secured by the collateral and, under
certain circumstances, the new Second Priority Notes and any untendered old
Second Priority Notes will have the benefit of the letter of credit. See
"--Security."

     The new Second Priority Notes and any untendered old Second Priority Notes
will bear interest at a rate of 12% per annum from the date of initial issuance
of the old notes until the principal of the old notes is paid or made available
for payment. Interest on the new notes will be payable in cash semi-annually on
June 30 and December 31 of each year, commencing December 31, 1999 to the person
in whose name the relevant new Second Priority Exchange Note or the untendered
old Second Priority Note is registered at the close of business on the preceding
June 15 or December 15, as the case may be. On any interest payment date
following the delivery of the first vessel, if we cannot pay all accrued and
unpaid interest on both the new Second Priority Notes and any untendered old
Second Priority Notes by applying cash in the Revenue Account, then we may pay
the interest through the issuance to the holders of the new Second Priority
Notes and any untendered old Second Priority Notes of additional new Second
Priority Notes having an aggregate principal amount equal to the deficiency in
cash available to pay interest. We may not issue more than $20.9 million in
aggregate principal amount of additional Second Priority Notes.

REDEMPTIONS

     Except as set forth below, we do not have the option to redeem the new
notes prior to June 30, 2002. On and after that date, we may redeem the new
First Priority Notes and the new Second Priority Notes, in whole or in part, at
any time or from time to time, upon not less than 30 days' nor more than 60
days' prior notice mailed by first-class mail to the registered address of each
noteholder, at the redemption prices set forth in the table below (expressed as

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):

</TABLE>

     At any time and from time to time prior to June 30, 2000, we 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 of Navigator Holdings (with the cash proceeds thereof to the extent
actually contributed to Navigator Gas Transport) 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 new First Priority Notes) and 112% (in the
case of the new Second Priority Notes), plus in each case accrued interest to
the redemption date, subject to the


                                       82
<PAGE>

right of holders of record on the relevant record date to receive interest due
on the relevant interest payment date. At least $100 million aggregate principal
amount of new First Priority Notes and any untendered old First Priority Notes
and $45 million aggregate principal amount of new Second Priority Notes and any
untendered old Second Priority Notes must remain outstanding after each
redemption.

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

Mandatory Redemption upon the Occurrence of Certain Events

     If an Owner elects to terminate its building contract for its vessel
because of a material breach by the builders, including a failure to pay
liquidated damages for any delay in the delivery of the vessel, the new 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 principal amount of the
notes allocated to the vessel and for each other vessel that has not been
accepted by its Owner as of the date of the termination, at a redemption price
equal to 100% of the principal amount of the notes allocated to the vessels 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 (1) the
receipt of the refund amount for the related building contracts and (2) 60 days
after the termination of the building contracts by the affected Owners.

     If a vessel is subject to total loss, the new 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 principal amount of the notes allocated to the
particular 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 (1) the
receipt of the insurance proceeds received for such total loss and (2) 60 days
after such total loss was deemed to have occurred.

     It is possible that we may not have sufficient funds available to effect
these redemptions.

Selection and Notice

     Unless otherwise expressly stated, if the new notes are to be redeemed in
part, the selection of the new notes to be redeemed will be made by the
applicable trustee on a pro rata basis, by lot or by such other method as the
trustee in its sole discretion shall deem to be fair and appropriate. In all
cases the new notes may be redeemed in multiples of $1,000 only, and subject
always to the provisions described above. Any notice of redemption will specify:

     o    the new notes subject to redemption;

     o    whether the new notes are to be redeemed in whole or in part, and the
          aggregate principal amount of the new notes to be redeemed; and


                                       83
<PAGE>

     o    the date of redemption.

     Once a new note or portion thereof has been redeemed, interest will cease
to accrue on that note as of the redemption date.

Additional Amounts

     All payments of, or in respect of, principal of and any premium and
interest on the new notes, and all payments pursuant to the guarantees, will 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 ("Taxes"), imposed or levied by or on behalf of, or within, the
Isle of Man, or the jurisdiction of incorporation of any successor to us or any
of the Owners, or any political subdivision or taxing authority thereof or
therein, unless the Isle of Man or the jurisdiction of incorporation of any
successor to us or any of the Owners or any such authority requires the Taxes to
be withheld or deducted. No Isle of Man law restricts the import or export of
capital into the island, and no Isle of Man law restricts the right of Isle of
Man non-resident Owners to hold the notes.

     In the event that any such authority requires the taxes to be withheld or
deducted, we, the Owners or any successor will pay such additional amounts of,
or in respect of, principal and any premium and interest on, or payments
pursuant to the guarantees ("Additional Amounts") as may be necessary so that
the net amount received by each holder of a note, 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.
However, no Additional Amounts will be payable for or on account of any of the
following events or combination of events:

     o    Taxes that would not have been imposed but for:

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

     o    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 new note to comply with our request or a request of any of the
          Owners addressed to the holder (1) to provide reasonable information
          concerning the nationality, residence or identity of the holder or
          such beneficial owner or (2) to make any reasonable declaration or
          other similar claim or satisfy any reasonable information or reporting
          requirement, which, in the case of (1) or (2), 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
          the tax, assessment or governmental charge; or

     o    the existence of any present or former connection between the holder,
          or between a fiduciary, settlor, beneficiary, member or shareholder
          of, or



                                       84
<PAGE>

          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, 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;

     o    the presentation of such new note for payment in the Isle of Man or
          any Successor Jurisdiction or any of their respective territories or
          political subdivisions, unless such new note could not have been
          presented for payment elsewhere; or

     o    the presentation of such new note more than 30 days after the date on
          which the payment in respect of such new 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 new note for payment on any day within such period of
          30 days.

     No Additional Amounts will be paid with respect to any payment of the
principal of or any premium or interest on any such new 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 the Additional
Amounts had it been the holder of the new note. We or the relevant Owners will
also (1) make such withholding or deduction and (2) remit the full amount
deducted or withheld to the relevant authority in accordance with applicable
law. We or the relevant Owners will furnish to holders of new 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 the payment by us or
the relevant Owners.

     Whenever there is mentioned, in any context, the payment of the principal
of or any premium or interest on, or in respect of, any new note, any payment
pursuant to the guarantees or the net proceeds received from us or the Owners on
the sale or exchange of any new note, the mention shall be deemed to include
mention of the payment of Additional Amounts provided for in the indentures to
the extent that, in the context, Additional Amounts are, were or would be
payable pursuant to the indentures.

     We or the relevant Owners 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 new notes or the guarantees or any other document or
instrument in relation thereto, or the receipt of any payments with respect to
the new 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 new notes or the guarantees or any other document or


                                       85
<PAGE>

instrument following the occurrence of any event of default with respect to the
new notes, and has agreed to indemnify the holders for any taxes paid by the
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 laws,
regulations or published tax rulings either generally or in relation to any
particular new notes, which change or amendment becomes effective on or after
the date of issuance of the old notes or which change in official
administration, application or interpretation was not available to the public
prior to the date of issuance of the old notes and we or the relevant Owners
receives notice of the change and it is determined by us or the relevant Owners
that we or the relevant Owners would be required to pay, or that we or the
relevant Owners would be substantially likely to be required to pay, any
Additional Amounts pursuant to the indentures or the terms of any new note in
respect of interest on the next interest payment date, and that the obligation
cannot be avoided by us or the relevant Owners taking reasonable measures
available to us, then we may, at our option, redeem all, but not less than all,
of the new notes in respect of which such additional amounts would be so payable
at any time. We must give not less than 30 nor more than 60 days' written notice
and pay a redemption price equal to 100% of the principal amount of the notes
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. No such notice of redemption may be given
earlier than 60 days prior to the earliest date on which we or the relevant
Owners would be obligated, or substantially likely to be obligated, to pay such
Additional Amounts were a payment in respect of the new notes or the guarantees
then due, and at the time any such redemption notice is given, the obligation,
or substantial likelihood, to pay such Additional Amounts must remain in effect.
It is possible that we will not have sufficient funds to effect this redemption.

GUARANTEES

     Payment of the principal of, and any premium and interest on, the new
notes, payment to the letter of credit issuer of our obligations under the
Letter of Credit Reimbursement Agreement, and our 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 is fully and
unconditionally guaranteed jointly and severally, on a secured basis by each of
the Owners. Each of these guarantees 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 New Notes
and Guarantees" and "--We are subject to fraudulent conveyance statutes that may
result in a declaration of insolvency which could interfere with our ability to
meet our payment obligations."

SECURITY

     Pursuant to the Intercreditor Agreement, the collateral agent is holding
and will hold the collateral in trust for the benefit of the holders of the new
notes and any untendered old 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 date of initial issuance of the old notes, to secure our obligations
under the indentures, the Security Agreements, the Letter of Credit
Reimbursement Agreement and the notes, (1) Navigator Holdings pledged to the
collateral agent, for the benefit of the holders of the notes, the letter of
credit issuer and the trustees, all our issued capital (the "Holdings Pledge"),
(2) we pledged to the collateral agent, for the benefit of the holders of the
notes, the letter of credit issuer and the trustees, all the issued capital of
the Owners and the Intercompany Note, and (3) we granted a security interest in
all of our right, title and interest in the trust accounts and all cash,
securities, instruments or other property credited thereto or deposited therein.

     On the date of initial issuance of the old notes, 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 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:

     o    the building contract for its vessel;

     o    the Technical Supervision Agreement;

     o    the building contract guarantee for its vessel and the performance
          bonds;

     o    the trust accounts and all cash, securities, instruments or other
          property credited thereto or deposited therein;

     o    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 our account or such Owner, or otherwise
          pursuant to the terms of any Security Agreement;

     o    the Management Agreement;

     o    all rights of the 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;


                                       87
<PAGE>

     o    any and all assets of the Owner whether now owned or hereafter
          acquired; and

     o    all income, payments, proceeds, rights and claims, resulting from or
          arising out of the foregoing.

     On the delivery date of each vessel, the related Owner will grant to the
collateral agent, for the benefit of the holders of the notes, the letter of
credit issuer and the trustees, a security interest in all of the particular
Owner's right, title and interest in the following assets and documents acquired
by the Owner after the date of issuance of the old notes:

     o    its vessel in accordance with the terms and conditions of the related
          mortgage;

     o    all earnings and insurance policies in respect of the particular
          vessel;

     o    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 the Owner
          in and to the same and every part of the property;

     o    all requisition proceeds and insurance proceeds with respect to its
          vessel or any part thereof, to the extent of the collateral agent's
          interest therein as mortgagee of the vessel pursuant to the related
          mortgage; and

     o    all income, payments, proceeds, rights and claims, resulting from or
          arising out of the foregoing.

     The holders of the notes, the letter of credit issuer and the trustees, for
fees owed, 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 for a total
loss of any vessel, the trustees will instruct the collateral agent to release
the lien on the 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 for the vessel. In connection with the termination by an
Owner of the related building contract because of a material breach 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 termination, the trustees
will instruct the collateral agent to release the liens on the building
contracts and the related collateral and to release the related Owners from
their obligations under their guarantees upon receipt by the collateral agent of
the rescission amounts for the vessels.

INTEREST DRAWS ON THE LETTER OF CREDIT

     On the date of initial issuance of the old notes, 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 notes and the trustees. Interest draws under the
letter of credit are not available until after the delivery


                                       88
<PAGE>

date of the first vessel. Three business days prior to each interest payment
date thereafter, the collateral agent will determine if there are sufficient
funds in the Revenue Account to pay the interest due on the notes or if a note
interest shortfall exists. If a note interest shortfall exists, the collateral
agent will make an interest on the letter of credit in an amount equal to the
lesser of (1) the note interest shortfall, less any portion of the note interest
shortfall attributable to interest payable pursuant to a Registration Default,
and (2) the maximum amount available under the letter of credit. No later than
the business day prior to an interest payment date, the letter of credit issuer
will remit the draw amount to the collateral agent and the collateral agent will
deposit the 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 permitted to make an
interest draw to pay interest on the new Second Priority Notes until and unless
we shall have, prior to or on the date of the interest draw, issued additional
new Second Priority 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 new Second Priority Notes. On the first business day of
each calendar month:

     o    subject to the prior payment of any required:

          (a)  Monthly Operating Deposit and

          (b)  Manager's Fee, if the date is also a Management Fee Payment Date,
               available cash in the Revenue Account will be paid to satisfy
               unpaid fees under 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 remaining funds, of all
               working capital draws outstanding on that date and then all
               interest draws outstanding; and

     o    if the date is also an interest payment date, after the delivery date
          of the first vessel, the repayment of all draws under the letter of
          credit outstanding on that date will be subject to the prior payment
          of any required fees and expenses due to the trustees and the
          collateral agent under the indentures and the Intercreditor Agreement.
          See "--Priorities of Payment--Revenue Account."

RANKING

     The old notes are and the new notes will be secured obligations of
Navigator Gas Transport. The First Priority Notes rank ahead of the Second
Priority Notes. The Second Priority Notes rank equally with any additional
Second Priority Notes that may be issued. The new First Priority Notes rank
equally with any untendered old First Priority Notes. The new Second Priority
Notes rank equally with any untendered old Second Priority Notes. The holders of
the new notes will have a claim against the collateral securing the new notes
which is subordinate in right of payment to any claim held by the letter of
credit issuer for any unreimbursed draws under the letter of credit. The maximum
amount of draws under the letter


                                       89
<PAGE>

of credit depends on the date of the draw and date of delivery of the vessels
but in no case will it exceed $50.0 million. The priority of payment of the
principal of, any premium, and interest on the new notes is as described under
"Description of the New Notes--Priorities of Payment--Revenue Account,"
- --"Priorities of Payment--Termination Account" and "--Application of Proceeds
Following an Event of Default." Neither we nor the Owners are permitted by the
indentures to incur any additional indebtedness, with certain limited
exceptions. See "Description of the New Notes--Certain Covenants."

MANDATORY OFFERS TO PURCHASE NEW NOTES

     Offer to Purchase with Available Cash. Commencing on June 30, 2001 and
semi-annually thereafter so long as the new First Priority Notes and any
untendered old First Priority Notes remain outstanding (each, an "Available Cash
Payment Date"), we will, to the extent of available cash, make an offer to each
holder of the new First Priority Notes and any untendered old First Priority
Notes, to purchase the holder's First Priority Notes and any untendered old
First Priority Notes, or at the holder's option, any part thereof, at a price
equal to 102% of the principal amount of the notes plus accrued and unpaid
interest to the date of purchase. We will not make an available cash offer if
our available cash is less than $1.0 million.

     Commencing on the first Available Cash Payment Date on or after the date
the new First Priority Notes and any untendered old First Priority Notes are
repaid in full and on each Available Cash Payment Date thereafter, we will, to
the extent of available cash, make an offer to each holder of the new Second
Priority Notes and any untendered old Second Priority Notes, to repurchase the
holder's new Second Priority Notes and any untendered old Second Priority Notes,
or at the holder's option, any part thereof, at a price equal to 102% of the
principal amount of the notes plus accrued and unpaid interest to the date of
purchase. We will not make an available cash offer if our available cash is less
than $1.0 million.

     Pursuant to the terms of the Intercreditor Agreement, we will have the
ability from time to time to withdraw available cash from the Revenue Account to
make purchases of new notes in open market transactions. If we purchase new
notes in open market transactions, the amount of available cash in the Revenue
Account on subsequent Available Cash Payment Dates will be reduced.

     Offer to Purchase upon Change of Control. If a change of control occurs, we
will make an offer to each holder of the new First Priority Notes and to each
holder of the new Second Priority Notes, to purchase the holder's notes (subject
to the limitation described below under "--Source of Funds to Purchase Notes"),
at a price equal to 101% of the outstanding principal amount of the notes, plus
accrued and unpaid interest to the date of purchase (the "Change of Control
Payment"). We will not make a change of control offer following a change of
control if a third party makes an offer which, if it had been made by us, would
constitute a change of control offer. We will purchase any and all new First
Priority Notes validly tendered pursuant to a change of control offer prior to
purchasing any new Second Priority Notes validly tendered pursuant to the change
of control offer.



                                       90
<PAGE>

     A change of control means the occurrence of any of the following events:

          (1) prior to the first public offering of common stock of Navigator
     Holdings, the permitted holders, Cambridge Gas, Xenon and GEBAB and their
     related affiliates, 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
     Navigator Gas Transport, whether as a result of issuance of securities of
     Navigator Holdings or Navigator Gas Transport, any merger, consolidation,
     liquidation or dissolution of Navigator Holdings or Navigator Gas
     Transport, any direct or indirect transfer of securities by Navigator
     Holdings or otherwise. For purposes of this clause (1) and clause (2)
     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;

          (2) 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 (1) above, except that for
     purposes of this clause (2) 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 Navigator Gas Transport. The permitted holders must
     beneficially own (as defined in clause (1) above), directly or indirectly,
     in the aggregate a lesser percentage of the total voting power of the
     voting stock of Navigator Gas Transport 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 (2), such other person shall be deemed to
     beneficially own any voting stock of a specified corporation held by a
     parent corporation, if such other person is the beneficial owner (as
     defined in this clause (2)), 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 (1) 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);

          (3) during any period of two consecutive years, individuals who at the
     beginning of such period constituted the board of directors of Navigator
     Holdings or Navigator Gas Transport, together with any new directors whose
     election by such board of directors or whose nomination for election by the
     stockholders of Navigator Holdings or Navigator Gas Transport,
     respectively, was approved by a vote of 662/3% of the directors of
     Navigator Holdings or Navigator Gas Transport, 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


                                       91
<PAGE>

     of directors of Navigator Holdings or Navigator Gas Transport,
     respectively, then in office;

          (4) either Cambridge Gas or GEBAB ceases to be a shareholder of
     Navigator Holdings; or

          (5) prior to the expiration of the warranty period of the last vessel,
     Tractebel Gas Engineering, including its affiliates, disposes of any of its
     shares in Navigator Holdings other than to an affiliate of Tractebel Gas
     Engineering.

     Procedure for Purchase of Notes. On the 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, we will provide, by mail
(first class, prepaid) written notice to the trustees and each holder of notes
stating that:

     o    we expect to have available cash on the next Available Cash Payment
          Date or a change of control has occurred;

     o    an available cash offer is being made and new notes of the applicable
          series having an aggregate principal amount equal to the amount of
          available cash divided by 1.02, the maximum principal amount will be
          accepted for payment (provided that no new Second Priority Note or any
          untendered old Secured Priority Note will be accepted for payment
          unless and until all new First Priority Notes and any untendered old
          First Priority Notes have been repaid in full) or a change of control
          offer is being made and all new notes validly tendered will be
          accepted for payment;

     o    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);

     o    any new note not tendered will continue to accrue interest pursuant to
          its terms;

     o    any new note accepted for payment pursuant to the available cash offer
          or the change of control offer will cease to accrue interest on and
          after the purchase payment date (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 we
          default on such payment;

     o    holders of new notes electing to have any new note or portion of a
          note purchased pursuant to an available cash offer or change of
          control offer must, prior to the close of business on the business day
          immediately



                                       92
<PAGE>

          preceding the applicable Purchase Payment Date, surrender their new
          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 their note;

     o    holders of new 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 the holder, the principal amount of new
          notes previously delivered for purchase, and a statement that the
          holder is withdrawing his election to have his new notes purchased;
          and

     o    holders whose new notes are being purchased in part will receive new
          notes of the same series and in principal amount equal to the
          unpurchased portion of the new notes surrendered. Each new note
          purchased and each new note issued shall be in a principal amount of
          $1,000 or integral multiples thereof.

     On the applicable Purchase Payment Date, we will:

     o    in the case of an available cash offer, purchase all notes or portions
          of a note tendered, provided that no Second Priority Note will be
          accepted for payment unless and until all First Priority Notes have
          been repaid in full, or in the case of a change of control offer,
          purchase all notes or portions of a note tendered, provided that no
          Second Priority Notes will be accepted for payment unless and until
          all tendered First Priority Notes have been repaid in full;

     o    deposit with the applicable trustee funds sufficient to pay the
          purchase price of all new notes of the applicable series or portions
          of notes so accepted; and

     o    cause to be delivered to the trustee, all new notes or portions of
          notes accepted for purchase together with an officers' certificate
          specifying the new notes or portions thereof accepted for payment.

The trustee will promptly mail, to the holders of new notes so accepted, payment
in an amount equal to the purchase price. We will issue and the trustee will
promptly authenticate and mail to holders a new note of such series equal in
principal amount to any unpurchased portion of the new notes of such series
surrendered. Each new note purchased and each new note issued will be in a
principal amount of $1,000 or integral multiples of $1,000. For an available
cash offer, if the aggregate amount of notes of a series tendered exceeds the
maximum principal amount, then the applicable trustee will select notes of the
series to be purchased ratably from each holder that tendered notes so that the
ratio of the principal amount of the notes to be purchased from each holder that
tendered notes to the aggregate principal amount of notes tendered by the holder
will, as nearly as practicable and subject to rounding, equal the ratio of the
maximum principal


                                       93
<PAGE>

amount to the aggregate principal amount of the notes of such series tendered
for the available cash offer. We will notify the holders of the notes 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.

     We will comply with Rule 14e-1 under the Exchange Act and any other
applicable securities laws and regulations, if such laws and regulations are
applicable to an available cash offer or a change of control offer. If the
provisions of any securities laws or regulations conflict with the provisions of
our agreement to purchase described above, we will comply with the applicable
securities laws and regulations and will not be deemed to have breached our
obligations described above.

     Source of Funds to Purchase Notes. In the event of an available cash offer,
the payment for the tendered new notes will 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
will be taken from the Revenue Account to the extent of available funds. As
discussed under "Risk Factors--In the event of a change of control, we may have
insufficient funds to meet our purchase obligations," 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 new notes tendered pursuant to the change of
control offer.

REGISTRATION RIGHTS

     In connection with the issuance of the old notes, we entered into a
registration rights agreement with the Initial Purchasers in which we agreed,
for the benefit of the holders of the old notes, at our expense, to use our
reasonable best efforts to cause the registration statement of which this
prospectus forms a part to be declared effective under the Securities Act.

     Promptly after the registration statement of which this prospectus forms a
part is declared effective, we have 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 SEC do not permit us to effect the exchange offer, or if any
Initial Purchaser so requests with respect to the notes that are not eligible to
be exchanged in the exchange offer or private exchange securities held by it
after consummation of the exchange offer, or any holder of notes (other than a
broker-dealer engaging in market-making or trading activities) that participates
in the exchange offer or participates in the exchange offer but does not receive
freely tradeable notes on the date of the exchange, we have agreed, at our
expense, to:

     o    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 SEC a shelf registration statement covering resales of the old
          notes;

     o    use reasonable best efforts to cause the shelf registration statement
          to be declared effective under the Securities Act; and


                                       94
<PAGE>

     o    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 old notes covered
          thereby have been sold.

We have agreed to use reasonable best efforts in the event of the filing of a
shelf registration statement, to provide to each holder of the old 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 old notes has become effective and take certain
other actions as are required to permit unrestricted resales of the old notes. A
holder of old notes that sells such old notes pursuant to the shelf registration
statement generally:

     o    will be required to be named as a selling securityholder in the
          related prospectus and to deliver a prospectus to the purchaser;

     o    will be subject to certain of the civil liability provisions under the
          Securities Act in connection with such sales; and

     o    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 old notes will be required to deliver certain
information to be used in connection with the shelf registration statement in
order to have its old notes included in the shelf registration statement.

     Since the exchange offer was not consummated by February 3, 1998,
additional interest is accruing and will accrue on the old notes from that date
to the date the exchange offer is consummated, at a rate of 0.50% of the
principal amount of the notes per annum. The additional interest is payable
semiannually in arrears on each interest payment date. Interest on the First
Priority Notes is accruing and will accrue at a rate of 11% and interest on the
Second Priority Notes is accruing and will accrue at a rate of 12 1/2% per annum
to reflect the 0.50% of additional interest until the earlier of consummation of
the exchange offer or the time when the new notes may be freely resold pursuant
to Rule 144(k). Under Rule 144(k) a nonaffiliate note holder who holds his notes
for at least two years may sell the securities without restriction. Additional
charter hire payments are or will be payable under the Charters in an aggregate
amount, in each case, equal to the additional interest.

     Upon consummation of the exchange offer, we generally will have satisfied
our obligations under the registration rights agreement to register the old
notes and we generally will have no further obligation to register the old
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

     Pursuant to the Intercreditor Agreement, the collateral agent has
established and is maintaining the following trust accounts: Pre-Funding
Account, Capitalized Interest Account,



                                       95
<PAGE>

Revenue Account, Letter of Credit Account, Operating Account, Casualty Account,
Termination Account and Collateral Account. Each of the accounts was established
in the name of the collateral agent for the benefit of the holders of the 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. We deposited into an account designated as the
"Pre-Funding Account" the following amounts on the date of issuance of the old
notes:

     o    the purchase price of each vessel;

     o    funds to pay all fees for the Owners' vessels due and payable prior to
          their delivery, including the Manager's fees and fees payable to the
          letter of credit issuer; and

     o    funds to pay the cost of the vessels' supplies. Earnings on temporary
          cash investments on funds on deposit in the Pre-Funding Account will
          also be deposited into the Pre-Funding Account.

In connection with the foregoing deposits, we delivered on the date of issuance
of the old notes to the trustees and the collateral agent a verification report
of a nationally recognized firm of independent accountants indicating that funds
deposited 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 of each vessel. Notwithstanding the delivery of this report, we
cannot assure you that the funds deposited 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 of each vessel.

     The collateral agent has made or will make payments from the Pre-Funding
Account as follows:

     o    on the date required for payment of a purchase price installment on an
          Owner's vessel, the purchase price installment then due for the vessel
          to be remitted to the builders if each of the trustees and the
          collateral agent has received written notice of the installment date
          at least three business days prior to the date, and if no material
          default exists under the related building contract;

     o    if the collateral agent and the trustees have received a written
          request for payment at least three business days prior to the date to
          be paid, an amount equal to any fee allocable to a vessel then due and
          payable prior to the delivery date of the particular vessel pursuant
          to the terms of the Management Agreement or the Letter of Credit
          Reimbursement Agreement, such payment to be remitted to the Manager or
          the letter of credit issuer. Amounts withdrawn from the Pre-Funding
          Account to make payments as described in this bullet point will not,
          in the aggregate, exceed the sum of all amounts deposited into the
          Pre-Funding Account;


                                       96
<PAGE>

     o    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 the final installment of the
          purchase price for the particular vessel, to be paid to the builders,
          plus fees and expenses incurred in connection with the recordation and
          filing of the related Security Agreements in the registration
          jurisdiction related to the vessel, to be remitted to the Manager;

     o    on each interest payment date occurring after the contractual delivery
          date of a vessel and before the actual delivery date of the particular
          vessel, an amount equal to the interest accrued on the principal
          amount of the notes for the vessel to be deposited in the Revenue
          Account;

     o    if an Owner elects to terminate the building contract for its vessel
          due to a material breach of the building contract by the builders, an
          amount equal to the remaining funds in the Pre-Funding Account to be
          deposited into the Termination Account to be used to redeem the
          portion of the new First Priority Notes and any untendered old First
          Priority Notes or the new Second Priority Notes and any untendered old
          Second Priority Notes as described above under
          "--Redemptions--Mandatory Redemption upon the Occurrence of Certain
          Events";

     o    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 payment of the fees and
          expenses incurred in connection with the recordation and filing of the
          related Security Agreements in the registration jurisdiction for the
          vessel to the Manager, to be deposited into the Revenue Account; and

     o    any and all investment earnings from temporary cash investments held
          in the Pre-Funding Account, for deposit in the Capitalized Interest
          Account.

     Capitalized Interest Account. On the date of issuance of the old notes, the
collateral agent, pursuant to the Intercreditor Agreement, deposited into an
account designated as the Capitalized Interest Account funds which, together
with the investment earnings estimated to be earned thereon from temporary cash
investments as well as any investment earnings from temporary cash investments
deposited therein from the Pre-Funding Account, will be sufficient to pay
interest, excluding additional interest payable on the new notes pursuant to a
Registration Default, on the principal amount of the notes allocated to each
vessel during the period prior to the contractual delivery date of the related
vessel. In connection with the foregoing deposit, we delivered on the date of
issuance of the old notes to the trustees and the collateral agent a
verification report of a nationally recognized firm of independent accountants
indicating that the payments scheduled to be received, without reinvestment, on
the temporary cash investments made with funds deposited in the Capitalized
Interest Account, 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 date of issuance of the old notes, will provide cash at such
times and in such amounts as


                                       97
<PAGE>

will be sufficient to pay, when due, interest on the principal amount of the
notes allocated to each vessel during the period prior to the contractual
delivery date of the particular vessel, excluding additional interest payable on
the new notes pursuant to a Registration Default. Notwithstanding the delivery
of this report, we cannot assure you that the funds deposited in the Capitalized
Interest Account will provide cash at the times and in the amounts as will be
sufficient to pay, when due, interest on the principal amount of the notes
allocated to each vessel during the period prior to the contractual delivery
date of the particular 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
funds equal to the interest accrued on the principal amount of the notes
allocated to a vessel and will deposit such amount into the Revenue Account. If
an Owner elects to terminate the building contract for its vessel due to a
material breach of the building contract by the builders, then the remaining
funds in the Capitalized Interest Account will be withdrawn from the Capitalized
Interest Account and deposited into the Termination Account to be used to redeem
the portion of the new First Priority Notes and any untendered old First
Priority Notes, or the Second Priority Notes and untendered old Second Priority
Notes as described above under "--Redemptions--Mandatory Redemption upon the
Occurrence of Certain Events."

     Revenue Account. The following amounts will be deposited into an account
designated as the "Revenue Account":

     o    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;

     o    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;

     o    interest draws;

     o    working capital draws in an amount equal to additional interest being
          paid on the principal amount of the notes allocated to each vessel if
          a Registration Default has occurred to the extent the balance
          remaining in the Capitalized Interest Account on an interest payment
          date is insufficient to pay such additional interest; and

     o    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.



                                       98
<PAGE>

Deposits will also be made into the Revenue Account from time to time:

     o    from certain withdrawals of funds from the Pre-Funding Account, the
          Capitalized Interest Account and the Casualty Account, as described in
          this prospectus; and

     o    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 Payment--Revenue
          Account."

     Letter of Credit Account. No later than the business day prior to each
interest payment date for 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 designated as
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 will 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 designated
as the "Operating Account" an amount (the "Monthly Operating Deposit") by which
the balance, as of any date of determination, is the product of $500,000 and the
number of vessels as to which the delivery date has occurred, 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. On and after any
business day commencing 90 days prior to the delivery date of the first vessel,
as reasonably expected by us 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 or its assignee under the
Technical Supervision Agreement and the Commercial Management Agreement, the
collateral agent will make a working capital draw in the amount requested by the
Manager and deposit the draw amount into the Operating Account. The amount of
the working capital draw will not exceed the maximum amount then available under
the letter of credit for working capital draws.

     Casualty Account. The collateral agent will deposit into an account
designated as the Casualty Account: (1) any cash proceeds from the exercise of
remedies against a builder in respect of any vessel, other than amounts
representing the refund amount or the proceeds of the Performance Bonds or any
building contract guarantee; and (2) 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."

     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: (1) if no event of default has occurred or
is continuing, the Manager has certified to


                                       99
<PAGE>

the trustees and the collateral agent that such repairs are necessary or
desirable for the use, operation and maintenance of such vessel; and (2) 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 (1) or (2)
above, such amounts will be held in the Casualty Account if no event of default
has occurred or is continuing, and 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 Payment--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 designated as the Termination Account any
insurance proceeds or the Refund Amounts for the related vessel and any other
vessel that has not been accepted by the Owners as of the date of termination,
and any amounts collected in respect of the related building contract guarantees
and Performance Bonds. See "--Redemptions--Mandatory Redemption upon the
Occurrence of Certain Events". The refund amounts and any amounts collected
under the related building contract guarantees and the Performance Bonds,
together with the amounts withdrawn from the Pre-Funding Account and the
Capitalized Interest Account will be withdrawn from the Termination Account to
be paid first, to the letter of credit issuer in an aggregate amount equal to
the sum of:

     o    any accrued and unpaid fees owing under the Letter of Credit
          Reimbursement Agreement;

     o    all Working Capital Draws made with respect to the vessels which
          remain unreimbursed, together with accrued and unpaid interest
          thereon; and

     o    the allocated portion of Interest Draws for the vessels which remain
          unreimbursed, together with accrued and unpaid interest thereon and
          second, to redeem the new First Priority Notes and any untendered Old
          First Priority Notes or the new Second Priority Notes and any
          untendered Old Second Priority Notes 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:

     o    first, to the letter of credit issuer, the trustees and the collateral
          agent, an amount equal to any accrued and unpaid fees for the letter
          of credit issuer, trustees and the collateral agent, 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


                                      100
<PAGE>

          respective rights and the pursuit 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;

     o    second, to the letter of credit issuer, an amount equal to all working
          capital draws made with respect to the particular vessel which remain
          unreimbursed, together with interest thereon payable under the Letter
          of Credit Reimbursement Agreement;

     o    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;

     o    fourth, to the First Priority Trustee for the benefit of the holders
          of the new First Priority Notes and any untendered Old First Priority
          Notes, an amount equal to any accrued and unpaid interest for the new
          First Priority Notes and any untendered Old First Priority Notes then
          outstanding;

     o    fifth, to the Second Priority Trustee for the benefit of the holders
          of the new Second Priority Notes and any untendered old Second
          Priority Notes, an amount equal to any accrued and unpaid interest for
          the new Second Priority Notes and any untendered old Second Priority
          Notes then outstanding;

     o    sixth, to the First Priority Trustee for the benefit of the holders of
          the First Priority Notes and any untendered old First Priority Notes,
          an amount equal to the outstanding principal amount of the new First
          Priority Notes and any untendered old First Priority Notes;

     o    seventh, to the new Second Priority Trustee for the benefit of the
          holders of the new Second Priority Notes and any untendered old Second
          Priority Notes, an amount equal to the outstanding principal amount of
          the new Second Priority Notes and any untendered old Second Priority
          Notes; and

     o    eighth, to the Revenue Account, any remaining amounts.

     Collateral Account. The collateral agent will deposit into an account
designated as the Collateral Account:

     o    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";


                                      101
<PAGE>

     o    any other amounts 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";

     o    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

     o    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 the
funds in the following order of priority:

          (1) first, for deposit into the Operating Account, an amount equal to
     the Monthly Operating Deposit, as certified by the Manager;

          (2) second, to the letter of credit issuer, an amount, as certified to
     the collateral agent by the letter of credit issuer, equal to all accrued
     and unpaid interest on all outstanding draws under the letter of credit,
     and, after the delivery date of the last vessel, the sum of all accrued and
     unpaid fees payable under the letter of credit;

          (3) third, to the letter of credit issuer, an amount as certified to
     the collateral agent by the letter of credit issuer, equal to the aggregate
     amount of working capital draws outstanding on such date; and

          (4) fourth, to the letter of credit issuer, an amount, as certified to
     the collateral agent by the letter of credit issuer, equal to the aggregate
     amount of interest draws outstanding on such date.

The Manager is paid its fee on the first business day of a calendar quarter (the
"Management Fee Payment Date"). In the event that the first business day of any
calendar month is a Management Fee Payment Date, the application of funds
pursuant to subparagraphs (2), (3) and (4) above will be subordinate to the
payment of the Manager's Fee as set forth in the following paragraph. In the
event that the first business day of any calendar month is an interest payment
date, the


                                      102
<PAGE>

application of funds pursuant to subparagraphs (3) and (4) above will also be
subordinate to the payments set forth in subparagraph (1) below.

     On each Management Fee Payment Date after the delivery date of the first
vessel, the collateral agent will withdraw from the Revenue Account, to the
extent of available funds, an amount equal to the aggregate Manager's Fee then
payable pursuant to the Management Agreement, the Commercial Management
Agreement and the Technical Management Agreement, and will remit such amount to
the Manager.

     Subject to the priorities set forth in the preceding two paragraphs, on
each interest payment date the collateral agent will withdraw funds from the
Revenue Account, to the extent of available funds, and apply the funds in the
following order of priority:

          (1) prior to the delivery date of the last vessel, to the letter of
     credit issuer, the sum of all accrued and unpaid fees payable under the
     letter of credit;

          (2) after the delivery date of the first vessel, to the trustees and
     the collateral agent, on a pro rata basis in accordance with amounts owed,
     an amount, as certified by the respective trustee or the collateral agent,
     equal to the accrued and unpaid fees and expenses payable in respect of the
     indentures and the Intercreditor Agreement;

          (3) to the First Priority Trustee for the benefit of the holders of
     new First Priority Notes and any untendered old First Priority Notes, an
     amount, as certified to the collateral agent by the First Priority Trustee,
     equal to all accrued and unpaid interest to such interest payment date on
     the new First Priority Notes and any untendered old First Priority Notes;
     and

          (4) to the Second Priority Trustee for the benefit of the holders of
     new Second Priority Notes and any untendered old Second Priority Notes, an
     amount, as certified to the collateral agent by the Second Priority
     Trustee, equal to the accrued and unpaid interest to such interest payment
     date on the new Second Priority Notes and any untendered old Second
     Priority Notes.

     Any amounts that remain in the Revenue Account on an interest payment date
after application in accordance with the foregoing priorities will be treated as
available cash.

     From time to time after the delivery date of the first vessel, in the event
of an extraordinary expense incurred in order to maintain and operate a vessel
in accordance with the related mortgage, which expense is immediately due and
payable, the collateral agent will be required to withdraw from amounts on
deposit in the Revenue Account, an amount sufficient to meet such extraordinary
expense and will deposit such amount into the Operating Account.

     Letter of Credit Account. On each interest payment date after the delivery
date for the first vessel, any amounts on deposit in the Letter of Credit
Account will be withdrawn by the collateral agent and transferred into the
Revenue Account and applied on such interest payment date solely to pay amounts
described in clauses (2) and (3) of the third paragraph under


                                      103
<PAGE>

"--Revenue Account." However, such amounts will not be applied to pay amounts
owed as described in such clause (3) unless we shall have, prior to or on such
interest payment date, issued additional new Second Priority Notes in an
aggregate principal amount of $20.9 million as described under "--Terms of the
New Notes--Second Priority Notes."

     Operating Account. The Manager will have the right to withdraw amounts on
deposit in the Operating Account, from time to time, to pay the operating
expenses of: (1) vessels as to which the delivery date has occurred; and (2) to
the extent of working capital draws deposited therein, vessels the delivery date
of which is reasonably expected by us to occur within 90 days of the date of
such withdrawal date. On the fifteenth day of each January, April, July and
October, the Manager will provide to the trustees and the collateral agent a
reasonably detailed statement setting forth, on an aggregate and per vessel
basis, how the amounts withdrawn from the Operating Account were applied during
the previous calendar quarter.

APPLICATION OF PROCEEDS FOLLOWING AN EVENT OF DEFAULT

     Upon the occurrence of (1) an event of default under either of the
indentures or (2) an event of default under the Letter of Credit Reimbursement
Agreement, the related trustee or the letter of credit issuer may, subject to
the terms and provisions of the Intercreditor Agreement, declare all amounts
owing under the applicable indenture or the Letter of Credit Reimbursement
Agreement to be immediately due and payable and, subject to the terms of the
Intercreditor Agreement, direct the collateral agent to take action to enforce
the remedies contained in the applicable indenture or the Letter of Credit
Reimbursement Agreement, as the case may be.

     Under the Intercreditor Agreement, all amounts on deposit in the Trust
Accounts which may be distributed in the event of an event of default, will be
distributed on a distribution date selected by the collateral agent or at the
request of the letter of credit issuer or the holders (in the aggregate) of a
majority of then outstanding notes of both series, in the following order of
priority, to the extent of available funds:

     o    first, to the letter of credit issuer, the trustees and the collateral
          agent, an amount equal to any accrued and unpaid 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 pursuit 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;

     o    second, to the letter of credit issuer, an amount equal to any amounts
          owing pursuant to the Letter of Credit Reimbursement Agreement with
          respect to working capital draws;

     o    third, to the letter of credit issuer, an amount equal to any amounts
          pursuant to the Letter of Credit Reimbursement Agreement with respect
          to interest draws;


                                      104
<PAGE>

     o    fourth, to the First Priority Trustee for the benefit of the holders
          of the new First Priority Notes and any untendered old First Priority
          Notes, an amount equal to any accrued and unpaid interest in respect
          of the new First Priority Notes and any untendered old First Priority
          Notes then outstanding;

     o    fifth, to the Second Priority Trustee for the benefit of the holders
          of the new Second Priority Notes and any untendered old Second
          Priority Notes, an amount equal to any accrued and unpaid interest in
          respect of the new Second Priority Notes and any untendered old Second
          Priority Notes, then outstanding;

     o    sixth, to the First Priority Trustee for the benefit of the holders of
          the new First Priority Notes and any untendered old First Priority
          Notes, an amount equal to the outstanding principal of the new First
          Priority Notes and any untendered old First Priority Notes;

     o    seventh, to the Second Priority Trustee for the benefit of the holders
          of the new Second Priority Notes and any untendered old Second
          Priority Notes, an amount equal to the outstanding principal of the
          new Second Priority Notes and any untendered old First Priority Notes;
          and

     o    eighth, to us, our successors or assigns, or to whomsoever may be
          lawfully entitled to receive the same, the excess, if any.

CERTAIN COVENANTS

     We have covenanted to restrict our activities. The following describes some
of these covenants.

     Limitation on Indebtedness. We will not incur, directly or indirectly, any
indebtedness, except that we may incur the following indebtedness:

     o    the old First Priority Notes, the new First Priority Notes, the old
          Second Priority Notes and the new Second Priority Notes; and

     o    indebtedness incurred under the Letter of Credit Reimbursement
          Agreement and under the Security Agreements.

     Limitation on Indebtedness of Owners. The Owners will not incur, directly
or indirectly, any indebtedness except that an Owner may incur the following
indebtedness:

     o    guarantees of the old First Priority Notes, the new First Priority
          Notes, the old Second Priority Notes and the new Second Priority
          Notes, our obligations under the Letter of Credit Reimbursement
          Agreement and any indebtedness incurred under the Security Agreements;


                                      105
<PAGE>

     o    the Intercompany Note; and

     o    Attributable Debt in respect of a UK Lease. However, prior to such
          incurrence, we must deliver to the trustees written confirmation from
          the rating agencies rating the notes that the entry into the UK Lease
          will not result in a downgrading, or possible downgrading, of the
          notes.

     Limitation on Restricted Payments. We will not, and will not permit any
Owner, directly or indirectly, to make a Restricted Payment. The prohibitions on
making Restricted Payments will not prohibit, with respect to the First Priority
Indenture, the redemption of new Second Priority Notes and any untendered old
Second Priority Notes, pursuant to the provisions described under
"--Redemptions--Mandatory Redemption upon the Occurrence of Certain Events," or
"Tax Redemption" or the purchase of new Second Priority Notes and any untendered
old Second Priority Notes, pursuant to the provisions described under
"--Mandatory Offers to Purchase Notes," in each case only to the extent that the
corresponding provisions in the First Priority Indenture have been complied with
prior to or on the date of such redemption or purchase. We and the Owners will
not, and we will not permit any Owner to, create or otherwise cause or permit to
exist or become effective any consensual encumbrance or restriction on the
ability of any Owner to:

     o    pay dividends or make any other distributions on its capital stock to
          us or another Owner or pay any indebtedness owed to us;

     o    make any loans or advances to us; or

          or restriction pursuant to an agreement in effect at or entered into
          on the date of initial issuance of the old notes.

     Limitation on Asset Sales. We will not, and will not permit any Owner to,

Lease and except sales of Incidental Assets.

     Limitation on Affiliate Transactions. Except for payments under the

will not, and shall not permit any Owner to, enter into or permit to exist any
transaction or series of related transactions, including the purchase, sale,
lease or exchange of any property, employee compensation arrangements or the
rendering of any service, with any affiliate of ours unless the terms thereof:

     o    are no less favorable to us or the Owner than those that could be
          obtained at the time of such transaction in arm's-length dealings with
          a person who is not an affiliate; and

     o    if the affiliate transaction involves an amount in excess of $1.0
          million, the terms are set forth in writing and have been approved by
          a majority of the

          members of the board of directors having no personal stake in such
          affiliate transaction; and

     o    if the affiliate transaction involves an amount in excess of $5.0
          million, the terms have been determined by a reasonably appropriate
          independent qualified appraiser to be fair, from a financial
          standpoint, to us and the Owners.

     The restrictions on transactions with affiliates will not prohibit:

     o    any Restricted Payment permitted to be paid pursuant to the covenant
          described under "--Limitation on Restricted Payments";

     o    any issuance of securities, or other payments, awards or grants in

          Management Agreement and, in the case of the Owners, the Technical
          Supervision Agreement, the Technical Management Agreement and the
          Commercial Management Agreement, in each case in the form in effect on
          the date of initial issuance of the old notes; and

     o    the payments made to the stockholders of Navigator Holdings on the
          date of initial issuance of the old notes as described in this
          prospectus under "Certain Transactions".

sell or otherwise dispose of any capital stock of an Owner, and will not permit
any Owner directly, or indirectly, to issue or sell or otherwise dispose of any
of its capital stock except (1) to us or another Owner or (2) directors'
qualifying shares.

               acceptable by institutional lenders to the shipping industry, as
               determined in good faith by the board of directors, and the
               Successor Issuer (if it is not us) will expressly assume, by a
               supplemental indenture, all the obligations of ours under the new
               notes and the applicable indenture;

     o    the Successor Issuer (if it is not us) will expressly assume all the
          obligations of ours under the Security Agreements and the Letter of
          Credit Reimbursement Agreement;

     o    immediately after giving effect to such transaction and treating any
          indebtedness which becomes an obligation of the Successor Issuer or
          any subsidiary as a result of such transaction as having been incurred
          by the Successor Issuer or such subsidiary at the time of such
          transaction, no default shall have occurred and be continuing;

     o    we will have delivered to the applicable trustee an officers'
          certificate and an opinion of counsel, each stating that the
          consolidation, merger or transfer and the supplemental indenture
          comply with the indenture; and

     o    we will have delivered an opinion of counsel in the jurisdiction where
          the Successor Issuer is domiciled (the "Applicable Jurisdiction")
          indicating that:


                                      108
<PAGE>

          (1)  any payment of interest, principal or any premiums on the new
               notes by the Successor Issuer to a holder will, after the
               consolidation, merger, conveyance, transfer or lease of assets,
               be exempt from withholding tax in the Applicable Jurisdiction and

          (2)  no other taxes on income, including taxable capital gains, will
               be payable under any tax law of the Applicable Jurisdiction by a
               holder of the new notes, who is or who is deemed to be a
               non-resident of the Applicable Jurisdiction in respect of the
               acquisition, ownership or disposition of the new notes including
               the receipt of interest, principal or premiums thereon, provided
               that such holder does not use or hold, and is not deemed to use
               or hold the new notes in carrying on a business in the Applicable
               Jurisdiction.

     The Successor Issuer will be the successor to us and will succeed to, and
be substituted for, and may exercise every right and power of, ours under the
indentures, but we, in the case of a conveyance, transfer or lease, will not be
released from our obligation to pay the principal of and interest on the new
notes.

     We will not permit any Owner to consolidate with or merge with or into, or
convey, transfer or lease, in one transaction or a series of transactions, all
or substantially all its assets to any person, except in connection with the
imposition of Additional Amounts and unless:

     o    the resulting, surviving or transferee person (the "Successor Owner")
          is a person organized and existing under the laws of the jurisdiction
          under which such subsidiary was organized or under

          (A)  the laws of the United States of America, or any State or the
               District of Columbia,

          (B)  the laws of the Republic of Liberia,

          (C)  the laws of the Isle of Man; or

          (D)  the laws of any other jurisdiction which at the time is generally
               deemed acceptable by institutional lenders to the shipping
               industry, as determined in good faith by the board of directors,
               and the Successor Owner (if it is not the Owner) will expressly
               assume, by a guarantee agreement, all the obligations of such
               Owner, if any, under its guarantee;

     o    the Successor Owner (if it is not the Owner) will expressly assume, by
          a guarantee agreement, all the obligations of such Owner, if any,
          under its guarantee of our obligations under the Security Agreements
          and the Letter of Credit Reimbursement Agreement;


                                      109
<PAGE>

     o    immediately after giving effect to such transaction or transactions on
          a pro forma basis (and treating any indebtedness which becomes an
          obligation of the Successor Owner as a result of such transaction as
          having been issued by such person at the time of such transaction), no
          default will have occurred and be continuing;

     o    we deliver to the applicable trustee an officers' certificate and an
          opinion of counsel, each stating that such consolidation, merger or
          transfer and such guarantee agreement, if any, complies with the
          applicable indenture; and

     o    we deliver an opinion of counsel in the Applicable Jurisdiction to the
          effect that:

          (1)  any payment of interest, principal or any premiums on the
               guarantee by the Successor Owner to a holder will, after the
               consolidation, merger, conveyance, transfer or lease of assets be
               exempt from withholding tax in the Applicable Jurisdiction; and

          (2)  no other taxes or income, including taxable capital gains, will
               be payable under any tax law of the Applicable Jurisdiction by a
               holder of the notes who is or who is deemed to be a non-resident
               of the Applicable Jurisdiction in respect of the acquisition,
               ownership or disposition of the notes, including the receipt of
               interest, principal or premiums, provided that the holder does
               not use or hold, and is not deemed to use or hold the notes in
               carrying on a business in the Applicable Jurisdiction.

     Limitation on Business Activities. We will not conduct any trade or
business other than holding investments in the Owners. We will not permit any
Owner to conduct any trade or business other than the ownership and operation of
its respective vessel and holding investments in us or one or more other Owners.

     Impairment of Security Interest. We will not, and will not permit any Owner
to, take or knowingly or negligently omit to take, any action, which action or
omission might or would have the result of materially impairing the security
interest with respect to the collateral for the benefit of the trustees and the
holders of the new notes. We will not, and will not permit any Owner to, grant
to any person other than the collateral agent, for the benefit of the trustees,
the letter of credit issuer and the holders of the new notes, any interest
whatsoever in any of the collateral.

     Amendments to Security Agreements. We will not, and will not permit any
Owner to, amend, modify or supplement, or permit or consent to any amendment,
modification or supplement of, the Security Agreements in any way that would be
adverse to the holders of the new notes.


                                      110

     SEC Reports. Whether or not required by the rules and regulations of the
SEC, we will furnish to the noteholders:

          were required to file such Forms, including a "Management's Discussion
          and Analysis of Financial Condition and Results of Operations" and,
          with respect to the annual financial information, a report thereon by

The quarterly financial information will be furnished within 60 days following
the end of each of our fiscal quarters and such annual financial information
will be furnished within 120 days following the end of our fiscal year.

          under the Exchange Act) of, 100% of the outstanding capital stock of
          Navigator Gas Transport;

     o    Navigator Holdings will not engage in any trade or business or hold
          any assets or make any investments, other than, in each case, the
          ownership of the capital stock of Navigator Gas Transport;

     o    Navigator Holdings will not, directly or indirectly, incur or permit
          to exist any lien of any nature whatsoever on any of its properties,

     5.   the failure by us to comply with our other agreements contained in the

          default continues for 60 days after notice;

     6.   indebtedness of Navigator Holdings, us or any Owner is not paid within

          its holders because of a default and the total amount of such
          indebtedness unpaid or accelerated exceeds $5.0 million (the "cross
          acceleration provision");

     7.   certain events of bankruptcy, insolvency or reorganization of
          Navigator Holdings, us or an Owner (the "bankruptcy provisions");

     8.   any judgment or decree for the payment of money in excess of $5.0
          million is entered against Navigator Holdings, us or an Owner, remains
          outstanding for a period of 60 days following such judgment and is not
          discharged, waived or stayed within 10 days after notice (the
          "judgment default provision");

     9.   a guarantee ceases to be in full force and effect, other than in

          and the Security Agreements, other than as a result of the
          satisfaction in full of all obligations


                                      112
<PAGE>

          under the applicable indenture and discharge of the applicable
          indenture, or any security interest created thereunder or in the
          Security Agreements is declared invalid or unenforceable or we,
          Navigator Holdings or any Owner asserts, in any pleading in any court
          of competent jurisdiction, that any such security interest is invalid
          or unenforceable (the "security default provision"); or

     11.  the Designated Owners cease to own (and vote at their discretion)
          voting stock of Navigator Holdings representing at least a majority of
          the voting stock of Navigator Holdings and cease to own capital stock
          of Navigator Holdings entitling them to at least a majority of the
          equity interests in Navigator Holdings.

A default under clause (4), (5) or (8) point will not constitute an event of
default under the indentures until the applicable trustee or the holders of 25%
in principal amount of the outstanding new notes of a series notify us of the
default and we do not cure such default within the time specified after receipt
of such notice.

     If an event of default occurs with respect to a series of new notes and is
continuing, the applicable trustee or the holders of at least 25% in principal
amount of the outstanding new notes of such series may declare the principal of
and accrued but unpaid interest on all the new notes of the series to be due and
payable. Upon such a declaration, principal and interest will be due and payable
immediately. If an event of default relating to certain events of our
bankruptcy, insolvency or reorganization occurs and is continuing, the principal
of and interest on all the new notes will automatically become and be
immediately due and payable without any declaration or other act on the part of
the trustees or any holders of the new notes. Under certain circumstances, the
holders of a majority in principal amount of the outstanding new notes of a
series may rescind any acceleration 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 indenture at the request or direction of any of the holders of
the new notes of such series unless the holders have offered the trustee
reasonable indemnity or security against any loss, liability or expense.

     Except to enforce the right to receive payment of any principal, premium or
interest when due, no holder of a new note of a series may pursue any remedy
under the applicable indenture or the new notes of such series unless:

     o    such holder has previously given the applicable trustee notice that an
          event of default is continuing;

     o    holders of at least 25% in principal amount of the outstanding notes
          of such series have requested such trustee to pursue the remedy;

     o    such holders have offered such trustee reasonable security or
          indemnity against any loss, liability or expense;


                                      113
<PAGE>

     o    such trustee has not complied with such request within 60 days after
          its receipt of notice and the offer of security or indemnity; and

     o    the holders of a majority in principal amount of the outstanding notes
          of the series have not given the trustee a direction inconsistent with
          such request within such 60-day period.

Subject to certain restrictions, the holders of a majority in principal amount
of the outstanding notes of a series have 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 trustee.
The trustee may refuse to follow any direction that conflicts with law or the
indenture or that such trustee determines is unduly prejudicial to the rights of
any other holder of a new 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, the trustee must mail to each holder of the new notes of
the affected 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 a new
note of a series, the 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 new notes of such series. We must deliver to each
trustee, within 120 days after the end of each fiscal year, a certificate
indicating whether the signers of the certificate know of any default that
occurred during the previous year. We must also deliver to each trustee, within
30 days after occurrence, written notice of any event which would constitute
certain defaults, their status and what action we are taking or propose to take
in respect of the event.

NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

     A director, officer or employee, of ours or Navigator Holdings will not
have any liability for any obligations of ours or Navigator Holdings 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 guarantees or for
any claim based on or connected with 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 notes of the
applicable series then outstanding. 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 notes of the same series then
outstanding. However, without the consent of each holder of a new note of the
series affected, no amendment may, among other things:

     o    reduce the amount of notes whose holders must consent to an amendment;

     o    reduce the rate of or extend the time for payment of interest on the
          note;


                                      114
<PAGE>

     o    reduce the principal of or extend the stated maturity of the note;

     o    reduce the premium payable upon the redemption of the note or change
          the time at which any note may be redeemed as described under
          "--Redemptions" above;

     o    make any note payable in money other than that stated in the note;

     o    impair the right of the holder to receive payment of principal of and
          interest on the notes or to institute suit for the enforcement of any
          payment on or with respect to the notes;

     o    make any change in the amendment provisions which require each
          holder's consent or in the waiver provisions;

     o    make any change in any guarantee or Security Agreement that would
          adversely affect the holders, or terminate the lien of the indenture
          or any Security Agreement on any property at any time subject to the
          lien or deprive the holder of the security afforded by the lien of
          such indenture or the Security Agreements; or

     o    make any change in the covenants described under "--Certain Covenants"
          above that would adversely affect the holders.

     Without the consent of any holder of the notes, we and the relevant trustee
may amend the applicable indenture or Security Agreements to cure any ambiguity,
omission, defect or inconsistency, to provide for the assumption by a successor
corporation of our obligations under the indenture, to provide for
uncertificated new notes in addition to or in place of certificated new notes,
to add guarantees of the new notes, to secure the notes, to add to our covenants
for the benefit of the holders of the notes or to surrender any right or power
conferred upon us, to make any change that does not adversely affect the rights
of any holder of the notes or to comply with any requirement of the SEC in
connection with the qualification of the indentures under the Trust Indenture
Act.

     The consent of the holders of the notes is not necessary under the
indentures to approve the particular form of any proposed amendment. It is
sufficient if the consent approves the substance of the proposed amendment.

     After an amendment under an indenture becomes effective, we must mail to
holders of the notes of the affected series a notice briefly describing the
amendment. The failure to give notice to all holders of the notes of the
affected series, or any defect as to the notice, will not impair or affect the
validity of the amendment.

     The new 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 new notes being


                                      115
<PAGE>

transferred for registration of transfer. We may require payment of a sum
sufficient to cover any tax, assessment or other governmental charge payable in
connection with transfers and exchanges.

DEFEASANCE

     We may at any time terminate all our obligations under the notes of a
series and the applicable indenture ("legal defeasance"), except for some
obligations, including those concerning the defeasance trust and obligations to
register the transfer or exchange of the new notes of such series, to replace
mutilated, destroyed, lost or stolen new notes of such series and to maintain a
registrar and paying agent in respect of the new notes of such series. We may at
any time terminate our obligations under the notes of a series and the
applicable indenture under "--Mandatory Offers to Purchase New 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 (4) of the
first paragraph under, and in the third paragraph under, "--Certain
Covenants--Merger and Consolidation" above ("covenant defeasance").

     We may exercise our legal defeasance option for a series of notes
notwithstanding our prior exercise of our covenant defeasance option for such
series. If we exercise our legal defeasance option for a series of notes,
payment of the notes of such series may not be accelerated because of an event
of default. If we exercise our covenant defeasance option for a series of notes,
payment of the notes of such series may not be accelerated because of an event
of default specified in clause (4), (5) or (7) (with respect only to Owners), or
in clauses (8) through (11) under "--Defaults" above or because of our failure
of to comply with clause (4) of the first paragraph, or with the third
paragraph, under "--Certain Covenants--Merger and Consolidation" above. If we
exercise our legal defeasance option or our covenant defeasance option for a
series of notes, each Owner will be released from all the obligations of its
guarantee and the Security Agreements for such series.

     In order to exercise either defeasance option for a series of notes, we
must irrevocably deposit in trust with the applicable trustee money or U.S.
Government Obligations for the payment of principal and interest on the notes of
such series to redemption or maturity, as the case may be. We must also comply
with other conditions, including delivery to the applicable trustee of an
opinion of counsel indicating that holders of the new 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. In the case of legal
defeasance only, this 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, our exercise of either defeasance option may
not be enforceable if the defeasance improves the position of noteholders of
either series of notes as against any other creditor of ours, whether actual,
contingent or otherwise. We may not exercise our legal defeasance or covenant
defeasance options unless the rating agencies confirm to the


                                      116
<PAGE>

applicable trustee in writing that such exercise will not result in a ratings
decline with respect to either series of notes.

CONCERNING THE TRUSTEES

     United States Trust Company of New York is the trustee under the First
Priority Indenture and has been appointed by us as registrar and paying agent
for the new First Priority Notes and any untendered old First Priority Notes.

     United States Trust Company of New York has been appointed as the exchange
agent for the exchange offer.

     The Chase Manhattan Bank is the trustee under the Second Priority Indenture
and has been appointed by us as registrar and paying agent for the Second
Priority Notes and any untendered old Second Priority Notes.

     United States Trust Company of New York is the collateral agent under the
Intercreditor Agreement.

     The holders of a majority in principal amount of the outstanding 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, the 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 these provisions, the trustee is under no obligation
to exercise any of its rights or powers under the indenture at the request of
any holder of notes of the applicable series, unless the holder has offered to
the trustee security and indemnity satisfactory to it against any loss,
liability or expense and then only to the extent required by the terms of the
indenture.

     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

     The indentures, the Intercreditor Agreement, the new 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. The
building contract guarantees and the performance bonds are governed by the laws
of England.

ENFORCEABILITY OF JUDGMENTS

                                      117

interest on the new notes, may not be collectible within the United States. See

          Gas Transport, other than an Owner, including the exercise of any

          each case due within one year of the date of acquisition, or

<PAGE>

          o    the making of any investment in any person, other than a
               Permitted Investment.

     "Sale Leaseback Transaction" means an arrangement relating to property now

transfers such property to a person and Navigator Gas Transport or an Owner
leases it from such person.

     "Security Agreements" means the Intercreditor Agreement, the mortgages, the

          confiscation of the vessel or a requisition by a governmental

Any actual loss of the vessel shall be deemed to have occurred at 1200 hours
Greenwich Mean Time ("GMT") on the actual date on which the vessel was lost or
in the event of the date of the loss being unknown then the actual total loss
shall be deemed to have occurred at 1200 hours GMT on the day next following the
day on which the vessel was last heard from. A constructive total loss shall be
deemed to have occurred at 1200 hours GMT on the earliest of:

     o    the date that notice of abandonment of the vessel is given to the
          insurers, provided a claim for total loss is admitted by the insurers;

     o    if the insurers do not admit such a claim, at the date and time GMT at

     "Total Loss Payment" means, as of any date of determination and with
respect to a total loss of a vessel, the sum of:

     o    the principal amount of the notes allocated to a vessel as of such
          date;

          effectively satisfied by depositing the purchase price in a defeasance
          trust.

The creation of any such UK lease will not result in the lowering of any ratings
then in effect with respect to the notes.

     "UK Lessor" means a leasing subsidiary of a United Kingdom clearing bank.

                    DESCRIPTION OF THE UNITS AND THE WARRANTS

     Pursuant to the offerings, the old Second Priority Notes were issued in
units. Each unit consists of one Second Priority Note in a principal amount of
$1,000 and 7.66 warrants. Each warrant entitles the warrant holder to purchase
one share of Navigator 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 (1) the commencement of the
exchange offer or the effectiveness of a shelf registration statement with
respect to the Second Priority Notes and (2) such date as the Initial Purchasers
may in their discretion deem appropriate. See "Description of the New
Notes--Registration Rights." See "Description of the New Notes" and "Description
of the Units and the Warrants" for further information concerning the Second
Priority Notes and the warrants.


                                      123
<PAGE>

     The warrants were issued under the Warrant Agreement dated as of August 7,
1997, between Navigator Holdings and United States Trust Company of New York, as
warrant agent. The exercise price of $.01 per share for the Navigator Holdings
common stock purchasable under the warrants was paid by the Initial Purchasers
as part of the purchase price of the units. No additional amounts are required
to be paid upon exercise of the warrants. The warrants will entitle the warrant
holders to purchase in the aggregate 25% of Navigator Holdings common stock on a
fully diluted basis as of the date of issuance of the warrants. The number of
shares of Navigator Holdings common stock is subject to adjustment in certain
cases referred to below. The warrants are currently exercisable and have been
exercisable since August 8, 1998, the first anniversary of their date of
issuance. Unless exercised, the warrants will automatically expire on June 30,
2007.

     The warrants and the underlying common stock of Navigator Holdings have not
been registered under the Securities Act and new warrants or new shares of
common stock of Navigator Holdings are not being offered in the exchange offer.
Accordingly, the warrants and the underlying shares of common stock of Navigator
Holdings should not be sold unless they are registered under the Securities Act
or they are sold pursuant to an exemption from registration.

                             BOOK-ENTRY REGISTRATION

     The old notes sold to Qualified Institutional Buyers were, and the new
notes will be, originally issued in fully registered book-entry form, and each
of the old notes and the new notes will be represented by a global note (each a
"Global Note") registered in the name of Cede & Co. 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 taken by DTC upon
instruction from DTC participants, and all references herein to distributions,
notices, reports and statements to holders shall refer, to distributions,
notices, reports and statements to DTC or Cede, as the registered holder of the
new notes or to DTC participants for distribution to beneficial owners of new
notes in accordance with DTC procedures. DTC has advised us 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 ("DTC
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").

     We expect that pursuant to procedures established by DTC, (1) upon deposit
of the applicable Global Note, DTC will credit the accounts of DTC participants
designated by the exchange agents with portions of the principal amount of the
applicable Global Note and (2) ownership of the new 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


                                      124
<PAGE>

respect to the interests of DTC's participants and DTC's indirect participants.
Consequently, the ability to transfer old notes or new notes evidenced by the
applicable Global Note will be limited to such extent.

     So long as Cede is the registered owner of any new notes, Cede will be
considered the sole holder under the indentures of any new notes evidenced by
the applicable Global Note. Beneficial owners of new notes evidenced by the
applicable Global Note will not be considered the owners or holders under the
indentures for any purpose, including with respect to the giving of any
directions, instructions or approvals to the indenture trustees. Neither we nor
the indenture trustees will have any responsibility or liability for any aspect
of the records of DTC or for maintaining, supervising or reviewing any records
of DTC relating to the new notes. Payments in respect of the principal of, any
premium, and interest on any new 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, we and the indenture trustees may treat the
persons in whose names new notes, including the applicable Global Note, are
registered as the owners for the purpose of receiving payments. Consequently,
neither we nor the indenture trustees have or will have any responsibility or
liability for the payment of amounts to beneficial owners of new notes. We
believe, however, that it is currently the policy of DTC to immediately credit
the accounts of the relevant participants with payments, in amounts
proportionate to their respective holdings of beneficial interests in the
relevant security as shown on the records of DTC. Payments by DTC's participants
and DTC's indirect participants to the beneficial owners of new 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 DTC participant through which the beneficial owner directly
or indirectly holds its beneficial interest, a certificated new note or new
notes, in exchange for all or part of such beneficial interest. In addition, the
new 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 new
notes and we are unable to locate a qualified successor or if we elect 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 certificated new notes. Upon surrender by DTC of the registered
global certificates representing the new notes and receipt of instructions for
re-registration, the indenture trustees will re-issue the new notes in
certificated form to beneficial owners or their nominees. These certificated new
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 THE 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 date of initial issuance of
the old notes 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"), us, Navigator Holdings and the Owners (the "Letter of
Credit Reimbursement Agreement"). The Letter of Credit is for a maximum amount
of $50.0 million, which is used to pay interest shortfalls and costs of up to an
aggregate of $45.5 million


                                      125

and working capital draws of up to $4.5 million to cover our working capital
requirements, if after the delivery of the first vessel, available funds in the
revenue account are insufficient to fund operation expenses.

     The maximum drawing amounts under the line of credit are: from the date 90
days prior to the delivery date of the first vessel to be delivered to and
including the date one day prior to the delivery date, a working capital draw of
up to $900,000 may be made; from the delivery date of the first vessel to and
including 91 days prior to the delivery date of the second vessel to be
delivered, an interest draw of up to $9,100,000 and a working capital draw of up
to $900,000 may be made; from the date 90 days prior to the delivery date of the
second vessel to be delivered to and including the date one day prior to the
delivery date of the second vessel to be delivered (assuming the first vessel
has been delivered), an interest draw of up to $9,100,000 and a working capital
draw of up to $1,800,000 may be made; from the delivery date of the second
vessel to and including the date 91 days prior to the delivery date of the third
vessel to be delivered, an interest draw of up to $18,200,000 and a working

first and second vessels have been delivered) an interest draw of up to
$18,200,000 and a working capital draw of up to $2,700,000 may be made; from the
delivery date of third vessel to and including the date one day prior to the
delivery date of the fourth vessel to be delivered, an interest draw of up to
$27,300,000 and a working capital draw of up to $2,700,000 may be made; from the
date 90 days prior to the delivery date of the fourth vessel to be delivered
(assuming the first, second and third vessels have been delivered), an interest
draw of up to $27,300,000 and a working capital draw of up to $3,600,000 may be
made; from the delivery date of the fourth vessel to and including the date 91
days prior to the delivery date of the fifth vessel to be delivered, an interest
draw of up to $36,400,000 and a working capital draw of up to $3,600,000 may be

vessel to the termination date of the Letter of Credit an interest draw of up to
$45,500,000 and a working capital draw of up to $4,500,000 may be made.

     The Letter of Credit Reimbursement Agreement provides that interest draws
and Working Capital Draws will be repaid by us, together with accrued interest,
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 New
Notes--Priorities of Payment--Revenue Account." We will instruct the collateral
agent to make:

     o    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

     o    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.


                                      126
<PAGE>

We will 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 will be payable from proceeds of the
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. We must pay to the letter of credit issuer:

     o    a fronting fee equal to 0.25% per annum on the aggregate outstanding
          face amount of the letter of credit;

     o    a participation fee equal to 1.00% per annum on the aggregate
          outstanding face amount of the letter of credit; and

     o    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.

Our reimbursement obligations 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:

     o    we 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;

     o    we, Navigator Holdings or any of the Owners fails 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;

     o    any representation, warranty, certification or statement made by us,
          Navigator 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 was incorrect in any
          material respect when made; and

     o    certain events of bankruptcy or insolvency of us, Navigator Holdings
          or any of the Owners.


                                      127
<PAGE>

Upon the occurrence of an event of default under the Letter of Credit
Reimbursement Agreement, the letter of credit issuer has the right to notify the
collateral agent that the letter of credit will be terminated within five days.
This notice would allow 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 will be reduced on a pro rata basis upon
the occurrence of a redemption of the notes as described under "Description of
the New Notes--Redemptions--Optional Redemption" and "--Mandatory Redemption
Upon the Occurrence of Certain Events."

                                  THE MORTGAGES

GENERAL

     Contemporaneously with the delivery of a vessel, the Owner of the vessel
will grant to the collateral agent a mortgage on the vessel to secure the
payment of all sums of money, whether for principal, any premium, interest,
fees, expenses or otherwise, from time to time payable by such Owner under its
guarantee, the payment of the principal of, any premium and interest on the
notes, the payment of all other sums payable by us under the indentures and the
payment of all other sums payable under the Security Agreements and the Letter
of Credit Reimbursement Agreement. On the delivery date of a vessel, the related
mortgage will be executed by the related Owner and the collateral agent and will
be recorded in accordance with the provisions of Liberian and/or Isle of Man
law. The maximum liability of each Owner under the mortgage on its vessel is
limited to the same extent as such Owner's maximum liability under its Owner
guarantee. See "Description of the New Notes--Guarantees."

CERTAIN REPRESENTATIONS AND WARRANTIES

     Each mortgage contains, among other things, the following representations
and warranties:

     Ownership of Vessel. Each Owner will represent and warrant that it is the
sole and lawful owner of the whole of its vessel, free from all liens, security
interests, mortgages, charges or encumbrances, other than the related 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
covenants, terms, conditions and provisions of its guarantee, the indentures,
the Letter of Credit Reimbursement Agreement and the other Security Agreements
and the transactions contemplated thereby;

     Litigation. Each Owner will represent and warrant that no actions or legal
proceedings exist or are threatened against such Owner which will materially
adversely affect the condition, financial or otherwise, of its vessel or will
enjoin or restrain the transactions contemplated hereby; and


                                      128
<PAGE>

     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 its vessel under the laws and regulations of the Isle of Man and/or 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 insurance 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 of the notes, 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, encumbrance or
charge on its vessel for longer than 30 days after the same becomes due and
payable and will pay or cause to be discharged or make adequate provision for
the satisfaction or discharge of all claims or demands, or will cause its vessel
to be released or discharged from any lien, encumbrance or charge.

     Maintenance of Vessel. Each Owner will at all times and without cost or
expense to the collateral agent maintain and preserve, or cause to be maintained
and preserved, its vessel in good running order and repair, so that such vessel
shall be, in so far as due diligence can make her so, tight, staunch, strong and
well and sufficiently tackled, appareled, 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


                                      129
<PAGE>

to be kept in such condition, as will entitle her to the highest classification
of Germanischer Lloyd, and annually will furnish the collateral agent a
certificate by Germanischer Lloyd that such classification is maintained.

     Transfer of Flag or Sale of Vessel. No Owner will transfer or change the
flag or port or documentation of its vessel, except to the United States or any
jurisdiction which at the time is generally deemed acceptable by 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.

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 of the vessel, 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 the Oil Pollution Act. 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 (1) its fair value and (2) 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
cancelable or subject to lapse without at least seven 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 New
Notes--Redemptions--Mandatory Redemption upon the Occurrence of Certain Events."
Unless the collateral agent will 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. In the event such
provision conflicts with the available reinsurance


                                      130
<PAGE>

arrangements of the issuers of the policy, such provision shall not be included
in the related insurance policy. Each Owner will be required to ensure, inter
alia, that seven business days prior written notice be given to the trustees and
to the collateral agent before the cancellation or modification of any
insurance.

INSURANCE PROCEEDS

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

     until the occurrence of an event of default:

     o    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

     o    any claim in respect of protection and indemnity insurance will 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 insurance
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:

     o    an event of default under the indentures or the Letter of Credit
          Reimbursement Agreement;

     o    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;

     o    default by the Owner in any material respect in the performance, or
          breach in any material respect of any covenant of the Owner under its
          mortgage or if any representation or warranty of the Owner made in its
          mortgage or in any certificate or other writing delivered in
          connection with its mortgage affecting the related vessel proves to
          have been inaccurate in any material respect as of the time when the
          same shall have been made,


                                      131
<PAGE>

          and, if such breach or default or inaccuracy is curable, continuation
          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;

     o    entry of a decree or order for relief by a court having jurisdiction
          in respect of the 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 the 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;

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

     o    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

     o    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:

     o    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
          these amounts will 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 amounts out of any and all property of the
          Owner whether covered by the related mortgage or otherwise;

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


                                      132
<PAGE>

     o    take and enter into possession of the Owner's vessel, at any time,
          wherever the same may be, without court decision or other legal
          process and without being responsible for loss or damage. 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 the vessel or in respect of
          any insurance thereon from any person whomsoever, accounting only for
          the net profits, if any, arising from the 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.

If at any time the collateral agent avails itself of the right given to it to
take the vessel:

     (1) 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

     (2) 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

     (3) 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

          o    sell the Owner's vessel or any share therein with or without the
               benefit of any charter party or other engagement by public
               auction or private contract without legal process at any 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 the vessel or any shares therein made by the
               collateral agent in pursuit 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


                                      133
<PAGE>

               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 Isle of Man.
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:

          o    liens against the vessel arising prior in time to the recording
               of the preferred mortgage;

          o    liens for damages arising out of tort;

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

          o    liens for crew wages;

          o    liens for general average;

          o    liens for salvage; and

          o    liens for expenses and fees allowed and costs imposed by courts
               of competent jurisdiction.

     Isle of Man 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, we cannot
assure you that, if enforcement proceedings are commenced against a vessel, such
vessel will be located in a jurisdiction having the same procedures and lien
priorities as the Isle of Man 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 the
Isle of Man 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.


                                      134
<PAGE>

     Since the notes are also secured by a pledge by us 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 following disclosure summarizes the material federal income tax
consequences under the Internal Revenue Code of 1986 (the "Code") expected to
result to holders whose old notes are exchanged for new notes in the exchange
offer. This discussion has been prepared with the advice of Graham & James, LLP,
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 Navigator
Holdings common stock or holders that have a functional currency other than the
U.S. dollar. 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 (1)
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 (2) 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.

     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 in
light of their particular investment circumstances or entity status.

     The exchange of old notes for new notes pursuant to the exchange offer will
not be treated as an "exchange" for federal income tax purposes because the new
notes will not be considered to differ materially in kind or extent from the old
notes. Rather, the new notes received by a holder will be treated as a
continuation of the old notes in the hands of the holder. As a result, no
material federal income tax consequences will result to holders exchanging old
notes for new notes.

                      CERTAIN ISLE OF MAN TAX CONSEQUENCES

     We are prohibited from making, and accordingly will not make, any offer or
invitation to any resident of the Isle of Man to subscribe for new notes.

     By acquiring and holding any new notes, 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 Navigator Gas Transport or Navigator Holdings will
not be permitted unless evidence is produced to the Registrar that the holder is
a trustee or nominee for a person not a resident for taxation purposes in the
Isle of Man or is a Manx exempt or international company.

     Special Isle of Man counsel has advised us that, in its opinion, no
withholding taxes will be imposed on payments of principal, interest or any
premium thereon with respect to the new 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 new notes. Investors should consult their own tax advisors regarding
whether the exchange of the new notes for old 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 any premium on the new notes,
we will make the required withholding and be 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, we are
obligated to take any lawful action to the extent necessary to prevent or avoid
the imposition of any withholding taxes, including changing our jurisdiction of
incorporation or residence. We will not be required to take, or fail to take,
any action (1) if in the opinion of counsel the act or failure to act would
violate applicable law or (2) if in our reasonable opinion the actions necessary
to avoid or prevent imposition of such taxes would be unduly burdensome. For
purposes of clause (2) of the immediately preceding sentence, a requirement to
change our jurisdiction of incorporation or residence will not be treated as
unduly burdensome unless changing our jurisdiction of incorporation or residence
to such other jurisdiction or location would subject us to charges in such other
jurisdiction, including but not limited to taxes imposed on or measured by our
income, receipts, property, assets, capital, sales or value-added.

                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives new notes 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 new notes. This prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of new notes received in exchange for old notes where
such notes were acquired as a result of market-making activities or other
trading activities. We have agreed that, for a period of 180 days after the
Expiration Date, we will make this prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resale. In
addition, until _______ __, 1999, all dealers effecting transactions in the new
notes may be required to deliver a prospectus.


                                      136
<PAGE>

     We will not receive any proceeds from any sale of new notes by
broker-dealers. New notes received by broker-dealers for their own account
pursuant to 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 new notes or a combination of such methods
of resale, at market prices prevailing at the time of resale, at prices related
to such prevailing market prices or 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 new notes. Any broker-dealer that
resells new notes that were received by it for its own account pursuant to the
exchange offer and any broker or dealer that participates in a distribution of
such new notes and any profit on any such resale of new notes 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 we will promptly send
additional copies of this prospectus and any amendment or supplement to this
prospectus to any broker-dealer that requests these documents in the letter of
transmittal. We have agreed to pay all expenses incidental to the exchange
offer, including the expenses of one counsel for the holders of the notes, other
than commissions or concessions of any brokers or dealers and will indemnify the
holders of the notes including any broker-dealers, against certain liabilities,
including liabilities under the Securities Act.

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

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

REPRESENTATIONS OF PURCHASERS

     Each purchaser of new notes in Canada who receives a purchase confirmation
will be deemed to represent to Navigator Gas Transport, Navigator Holdings and
the dealer from whom such purchase confirmation is received that:

          o    the purchaser is entitled under applicable provincial securities
               laws to purchase such new notes without the benefit of a
               prospectus qualified under such securities laws;


                                      137
<PAGE>

          o    where required by law, that such purchaser is purchasing as
               principal and not as agent; and

          o    such purchaser has reviewed the text above under "Resale
               Restrictions."

RIGHTS OF ACTION (ONTARIO PURCHASERS)

     The new notes being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario law. 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, Navigator
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, Navigator Holdings, the Owners or these persons. All or a substantial
portion of the assets of Navigator Gas Transport, Navigator Holdings, the Owners
and such persons may be located outside of Canada and, as a result, it may not
be possible to satisfy a judgment against Navigator Gas Transport, Navigator
Holdings, the Owners or such persons in Canada or to enforce a judgment obtained
in Canadian courts against Navigator Gas Transport, Navigator Holdings, the
Owners or these persons outside of Canada.

NOTICE TO BRITISH COLUMBIA RESIDENTS

     A purchaser of new notes to whom the Securities Act (British Columbia)
applies is advised that such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any new
notes acquired by such purchaser pursuant to the offerings. Such report must be
in the form attached to British Columbia Securities Commission Blanket Order BOR
#95/17, a copy of which may be obtained from Navigator Gas Transport. Only one
such report must be filed in respect of new notes acquired on the same date and
under the same prospectus exemption.

TAXATION AND ELIGIBILITY FOR INVESTMENT

     Canadian purchasers of new notes should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the new notes
in their particular circumstances and with respect to the eligibility of the new
notes for investment by the purchaser under the relevant Canadian legislation.

                                     RATING

     Moody's has rated the old First Priority Notes B1 and the old Second
Priority Existing Notes B3 and Standard & Poor's has rated the old First
Priority Notes B and the old Second Priority Notes CCC+. 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


                                      138
<PAGE>

agencies assigned to the notes address the likelihood of the receipt by holders
of the old 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 old notes may suffer
a lower than anticipated yield.

     We have not requested a rating on the notes by any rating agencies other
than those described above. 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
notes by the rating agencies described above.

                                  LEGAL MATTERS

     Certain legal matters with respect to the new notes offered hereby will be
passed upon for us, Navigator Holdings and the Manager by Graham & James LLP,
New York, New York and Cains, Douglas, Isle of Man.

to their seaworthiness and upkeep, and the placing of vessels in "classes"

provides insurance for the occurrence of such event due to the carrying of
contraband items on a vessel.

involving bulk cargoes.

     "Deadweight Tonne" ("dwt") is a unit of a vessel's capacity for cargo, fuel

national authority.

     "Freight" means the compensation for carriage of cargo.

     "General Average" is related to the deliberate sacrifice of property to

substantially all of its operating systems and taking measures to protect
against corrosion and other deterioration.

     "Loss of Hire Hull and Machinery Insurance" provides cover for the loss of

voyage. Under this type of charter, the shipowner pays all the operating costs
of the ship, including bunkers, canal and port changes, pilotage, towage and
ship's agency, while payment for cargo handling charges is subject to agreement
between the parties. Freight is generally paid per unit of cargo, such as a ton,
based on an agreed quantity, or as a lump sum irrespective of the quantity
loaded.

     "War Risks Policy" provides cover against the blocking and trapping of a
vessel, confiscation and damage resulting from hostilities, mines, strikes,
riots and civil commotions. However, a vessel subject to this form of insurance
cannot trade in a high risk area without the specific agreement of the insurer
and the payment of additional premiums. Pursuant to this insurance, a total loss
will be declared to have occurred after six months of arrest by a government,
civil war, sabotage, acts of terrorists and mines.

     The above shipping terms were supplied by the Dictionary of Shipping
Serials and other sources.

                   CONSOLIDATED NOTES TO FINANCIAL STATEMENTS

                           DECEMBER 31, 1998 AND 1997


1.   DESCRIPTION OF OPERATION:

     Navigator Holdings PLC (the "Company") is an Isle of Man public limited
     company. The Company was formed for the purpose of owning 100% of Navigator
     Gas Transport PLC (the "Issuer"), issue the Warrants to the Holders of the
     Second Priority Notes (see note 3 "Description of Warrants") and make a
     sizable equity contribution to the Issuer (see note 6 "Stockholders'
     Equity").

     Navigator Gas Transport PLC has been formed as an Isle of Man public
     limited company for the purpose of establishing, owning and financing five
     subsidiaries, 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 (individually referred to as the
     "Owner", or collectively, the "Owners"). Each Owner has been formed as an
     Isle of Man private limited company for the purpose of building and
     operating one of the five semirefrigerated gas carriers (the "Vessels").
     The operations of the Issuer will be limited to owning the Owners,
     receiving payments under the intercompany note, make payments of interest
     and principal on the notes, and fulfilling its obligations under the
     indentures, the intercreditor agreement, the letter of credit reimbursement
     agreement and the registration agreement. Between the issue date and the
     delivery date of each Vessel, the operation of each Owner will consist
     solely of entering into commercial arrangements in relation to the future
     operation of the Vessels, managing the construction of the Vessels, making
     payments of the management fees, paying installments under the building
     contracts, fulfilling its obligations under the management agreement, and
     guarantee. On and after the delivery of each Vessel, the operation of each
     Owner will consist solely of operating, maintaining, insuring and using the
     Vessel and conducting activities related thereto, receive payment under
     charters, contracts of affreightment and other contracts relating to the
     employment of its Vessel, receiving proceeds from the sale (if any) of its
     Vessel, making payments of interest and principal on the intercompany notes
     and any other permitted indebtedness, making payments of management fees,
     fulfilling its obligation under the management agreement and guarantee.


2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

     BASIS OF PRESENTATION

     The financial statements have been prepared in accordance with accounting
     principles generally accepted in the United States of America.



                                      A-5

CONSOLIDATED NOTES TO FINANCIAL STATEMENTS (CONTINUED)


     BASIS OF CONSOLIDATION

     The accompanying consolidated statements of financial condition include the
     accounts of the Company, the Issuer and the Owners. All intercompany
     accounts and transactions have been eliminated in consolidation.

     VESSELS UNDER CONSTRUCTION

     Vessels under construction are capitalized in accordance with contract
     payments made to the Builders. Vessels under construction also includes
     service of vessel design, technical supervision, structuring and providing
     performance bonds, and capitalization of interest incurred during the
     period of the vessels' construction.

     DEBT ISSUE COSTS

     Debt issue costs comprise expenses incurred in connection with the issuance
     of ship mortgage notes. Such expenses are being amortized over the life of
     the ship mortgage notes using the effective interest method.

     FAIR VALUE OF FINANCIAL INSTRUMENTS

     The methods and assumptions used in estimating the fair values of financial
     instruments are as follows:

        RESTRICTED CASH: The carrying value of the guaranteed investment
        contract is stated at contract value, which approximates fair value. The
        contract is with Pacific Life Insurance, a California life insurance
        company. The contract is held in the name of the United States Trust
        Company (the "Trustee") on behalf of the Issuer as the Indenture
        Trustee.

        SHIP MORTGAGE NOTES: Due to the existing market conditions in the
        shipping bonds industry, the value of the Ship Mortgage Notes (the
        "Notes") was negatively affected causing the Notes to decline in value.
        However, due to the instability of the market and the elapsed time
        between the date of the Consolidated Statements of Financial Condition
        and the date of issuance of the Ship Mortgage Notes, the decline in
        value is deemed to be immaterial.

     ACCOUNTING ESTIMATES

     The preparation of the financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statement. When recorded, actual results could differ from such
     estimates. The most significant assumption and estimate relate to vessels
     under construction.

     INCOME TAXES

     The Company is exempt from United States federal, state and local income
     taxes and has been granted exemptions from the statutory 20% tax on profits
     required to be assessed against Isle of Man companies.

     Certain entities are exempt from U.S. corporate income tax on U.S. source
     income from their international shipping operation if (i) their countries
     of incorporation exempt shipping operations U.S. persons from income tax
     (the "incorporation Test") and (ii) they meet the "Ultimate Owners Test." A
     company meets the Ultimate Owners Test if more then 50% of the value of its
     stock is ultimately owned by individuals who are residents of a foreign
     country that exempts U.S. persons from tax on shipping earnings. The
     Company is involved in international shipping operations which meet the
     Incorporation Test because the Company is incorporated in the Isle of Man,
     which provides the required exemption to U.S. persons involved in shipping
     operations, and the Company believes more than 50% of the value of its
     outstanding shares is owned by individuals who are residents of countries
     which provide the required exemption to U.S. persons involved in shipping
     operations. The issue of residence is, however, inherently factual and
     cannot be determined.

     Based on the foregoing, the Company expects all of its income to remain
     exempt from United States income tax. Accordingly, no provision for taxes
     has been made in the financial statements.

     Nonmonetary Transactions

     The transfer of nonmonetary assets to the Company by its shareholders in
     exchange for stock are recorded at the transferor's market value of
     services performed determined under generally accepted accounting
     principals.

3.   SHIP MORTGAGE NOTES:

     The Issuer placed, on August 7, 1997, through a private placement,
     $217,000,000 aggregate principal amount of 10 1/2% First Priority Ship
     Mortgage Notes Due 2007 (the "First Priority Notes") and together with
     Navigator Holdings PLC ("Holdings") placed 87,000 Units (the "Units"), each
     Unit consisting of one of the Company's 12% Second Priority Ship Mortgage
     Notes Due 2007 (a "Second Priority Note" and, together with the First
     Priority Notes, the "Notes") in a principal amount of $1,000 and 7.66
     Warrants (each a "Warrant"). The Notes are unconditionally and irrevocably
     guaranteed by each subsidiary of the Company (collectively, the
     "Guarantors"). The Notes will bear interest from August 7, 1997 (the "Issue
     Date") until the principal thereof is paid or made available for payment.
     Such interest will be payable semi-annually on June 30 and December 31 of
     each year, commencing December 31, 1997, to the person in whose name the
     relevant First Priority Notes or Second Priority Notes is registered at the
     close of business on the preceding June 15 or December 15.

     The Notes have priority of payment and are collateralized by (i) an
     assignment of each vessel; (ii) an assignment of the pre-funding account
     and capitalized interest account held by the Trustee (iii) an assignment of
     the Building Contracts and technical supervision agreement; (iv) an
     assignment of the commercial management agreement; (v) an assignment of the
     management agreement with a Company's affiliate; (vi) an assignment of the
     performance bonds; (vii) an assignment of the earnings and issuance
     proceeds related to each vessel and (viii) certain other collateral.

     DESCRIPTION OF WARRANTS

     The Warrants have not been registered under the Securities Act and are
     subject to certain restrictions on transfer. Holders of the Warrants and
     the shares of Company Common Stock underlying the Warrants will have
     certain rights to require the Company to file and have declared effective a
     registration statement with respect thereto or to purchase such Warrants
     and underlying shares. The Warrants when exercised, will entitle the
     holders thereof to acquire an aggregated 666,420 shares of the Company's
     Common Stock, representing in aggregated 25% of the shares of the Company's
     Common Stock on a fully diluted basis. The Warrants will be reflected on
     the balance sheet as a reduction of the Second Priority Notes amortized
     over the life of the debt using the Effective Interest Method.

     ADDITIONAL NOTES

     On the interest payment date following the delivery of the first vessel if
     cash available for distribution in the Revenue Account, as defined in the
     "Indenture Agreement", to the holder of the Second Priority Notes on such
     date is insufficient to pay all accrued and unpaid interest on the Second
     Priority Note, such interest may be paid through the issuance to the holder
     by the Issuer of additional Second Priority Notes having an aggregate
     principal amount equal to the deficiency in such available cash; provided
     further, however, that the Issuer may not issue more than $20.9 million in
     aggregate principal amount of such additional Second Priority Notes.

     Other than as set forth in the previous paragraph, the First Priority Notes
     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

     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 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 (as defined in "Builders Performance Bond",
     dated August 7, 1997) 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 a 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 in the "Indenture
     Agreement", dated August 7, 1997), the 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 issuance proceeds with respect
     to such Total Loss and (b) 60 days after such Total Loss was deemed to have
     occurred.

     DEBT COVENANTS

     The Notes include certain covenants that, among other things, limit the
     ability of the Issuer and the Owners to incur additional indebtedness, pay
     dividends or make certain payments, restrict distribution from Owners, sell
     assets, enter into certain mergers and consolidations, incur liens other
     than permitted liens and enter into certain transactions with affiliates.

     Letter of Credit

     The Issuer has entered into an Irrevocable Standby Letter of Credit
     Agreement (the "Agreement") with the Trustee and funding bank dated August
     7, 1997, for $50,000,000. The purpose of this Agreement is to provide
     securities for the holders of the mortgage notes regarding the repayment of
     principles and interest. The Agreement provides for two types of draws,
     interest draws and working capital draws. Under the terms of the Agreement,
     a maximum of $45,000,000 has been allocated for interest draws and
     $4,500,000 for working capital draws. The draws may only be used in certain
     increments and dates throughout the construction and post-delivery periods
     of the vessels, as defined in the Agreement. As of December 31, 1998, the
     issuer has no outstanding draws under the Agreement.

     Interest on the draws is charged at LIBOR plus one and one-quarter percent
     (1-1/4%) per annum.

     The Issuer is required under the Agreement to pay certain annual fees to
     sustain the Agreement. These fees are calculated at (1-1/4%) of the maximum
     available line of credit amount. These fees amount to $687,500 and $250,000
     for the periods ended December 31, 1998 and 1997, respectively, and have
     been included in other expenses on the Consolidated Statement of
     Operations. In addition, the funding bank has received an underwriting fee
     of $625,000 for the Agreement, which has been capitalized and will be
     amortized over the life of the mortgage notes.

4    RESTRICTED CASH:

     Restricted Cash is comprised of pre-funding and a capitalized interest
     account. These accounts were established in the name and under the control
     of the Trustee. The net proceeds of the Notes issued on behalf of the
     Company were deposited into the accounts in the form of a guaranteed
     investment contract. Restricted cash will be used primarily for the
     payments of interest and principal due on the Notes, management fees, and
     contract payments to the Builders for the construction of the vessels. At
     December 31, 1998 and 1997 the aggregate amount of Restricted Cash was
     $207,717,037 and $254,114,847, respectively.

5.   CONTINGENCIES AND COMMITMENTS:

     Future contractual payments to be made under the construction contracts for
     each of the succeeding year ending December 31, until completion are as
     follows:


               1998 ..............................   27,310,800

7.   RELATED PARTY TRANSACTIONS:

     On August 7, 1997, the following payments were disbursed to certain
     stockholders:

          a)  The amounts of $2.3 million and $2,273,696 were paid to a
              stockholder, CGTC, for structuring fees and costs of issuance of
              the Notes, respectively.

          b)  The amount of $2 million, $1 million to a stockholder, Xenon
              Shipping Inc., and $1 million to another stockholder, GEBAB, was
              paid for their services in developing charter contracts for the
              vessels during the pre-delivery period.

8.   CONCENTRATION OF CREDIT RISK:

     The Company has no sources for the payment of the principal of, and the
     interest on the Notes except for the pre-funding and capitalized interest
     accounts held by the Trustee. Accordingly, the Company's ability to pay
     debt service on the Notes is wholly dependent upon its financial condition,
     results of operations and cash flows when the vessels are in operation.

     The Company has five vessels under construction, all of which are being
     produced under contracts with one shipyard in the People's Republic of
     China ("PRC"). The production and delivery of these vessels is subject to
     the risk of nonperformance by the shipyard due to political or economic
     changes in the PRC, as well as interruption in sea or air transportation in
     the area. Although the Company has received various performance guarantees
     from the shipyard and its bank to recover its investment in the event of
     nonperformance, there can be no conclusive assurance that the
     counterparties will perform. Also, the Company's future shipping operations
     would be significantly disrupted if such event were to occur.

9.   MANAGEMENT AGREEMENTS:

     Each of the Owners entered into a Management Agreement with Navigator Gas
     Management Limited (an Isle of Man public limited company, the "Manager"),
     an affiliate of the Company. The Manager will manage their commercial and
     technical operations, including providing administrative services, causing
     the compliance of the Owners' covenants in the Notes and monitoring GEBAB's
     (through it's subsidiary "MarLink") performance under the Technical
     Supervision Agreement, Technical Management Agreement and Commercial
     Management Agreement. The Manager shall receive as compensation for its
     services the sum of $30,000 per annum per Vessel that has not been accepted
     by the related Owner and $120,000 per annum per Vessel that has been
     accepted by the related Owner. As of December 31, 1998 and 1997 Management
     fee expenses of $150,000 and $75,000, respectively, were included in other
     expenses on the Consolidated Statement of Operations and Retained Earnings.

1.   DESCRIPTION OF OPERATION:

     Navigator Holdings PLC (the "Company") is an Isle of Man public limited
     company. The Company was formed for the purpose of owning 100% of Navigator
     Gas Transport PLC (the "Issuer"), issue the Warrants to the Holders of the
     Second Priority Notes (see note 3 "Description of Warrants") and make a
     sizable equity contribution to the Issuer (see note 6 "Stockholders'
     Equity").

     Navigator Gas Transport PLC has been formed as an Isle of Man public
     limited company for the purpose of establishing, owning and financing five
     subsidiaries, 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 (individually referred to as the
     "Owner", or collectively, the "Owners"). Each Owner has been formed as an
     Isle of Man private limited company for the purpose of building and
     operating one of the five semirefrigerated gas carriers (the "Vessels").
     The operations of the Issuer will be limited to owning the Owners,
     receiving payments under the intercompany note, make payments of interest
     and principal on the notes, and fulfilling its obligations under the
     indentures, the intercreditor agreement, the letter of credit reimbursement
     agreement and the registration agreement. Between the issue date and the
     delivery date of each Vessel, the operation of each Owner will consist
     solely of entering into commercial arrangements in relation to the future
     operation of the Vessels, managing the construction of the Vessels, making
     payments of the management fees, paying installments under the building
     contracts, fulfilling its obligations under the management agreement, and
     guarantee. On and after the delivery of each Vessel, the operation of each
     Owner will consist solely of operating, maintaining, insuring and using the
     Vessel and conducting activities related thereto, receive payment under
     charters, contracts of affreightment and other contracts relating to the
     employment of its Vessel, receiving proceeds from the sale (if any) of its
     Vessel, making payments of interest and principal on the intercompany notes
     and any other permitted indebtedness, making payments of management fees,
     fulfilling its obligation under the management agreement and guarantee.


2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

     BASIS OF PRESENTATION
     ---------------------

     The financial statements have been prepared in accordance with accounting
     principles generally accepted in the United States of America.




                                      A-18

CONSOLIDATED NOTES TO FINANCIAL STATEMENTS (CONTINUED)



     BASIS OF CONSOLIDATION
     ----------------------

     The accompanying consolidated statements of financial condition include the
     accounts of the Company, the Issuer and the Owners. All intercompany
     accounts and transactions have been eliminated in consolidation.


     VESSELS UNDER CONSTRUCTION
     --------------------------

     Vessels under construction are capitalized in accordance with contract
     payments made to the Builders. Vessels under construction also includes
     service of vessel design, technical supervision, structuring and providing
     performance bonds, and capitalization of interest incurred during the
     period of the vessels' construction.

     DEBT ISSUE COSTS
     ----------------

     Debt issue costs comprise expenses incurred in connection with the issuance
     of ship mortgage notes. Such expenses are being amortized over the life of
     the ship mortgage notes using the effective interest method.

     FAIR VALUE OF FINANCIAL INSTRUMENTS
     -----------------------------------

     The methods and assumptions used in estimating the fair values of financial
     instruments are as follows:

        RESTRICTED CASH: The carrying value of the guaranteed investment
        contract is stated at contract value, which approximates fair value. The
        contract is with Pacific Life Insurance, a California life insurance
        company. The contract is held in the name of the United States Trust
        Company (the "Trustee") on behalf of the Issuer as the Indenture
        Trustee.

        SHIP MORTGAGE NOTES: The carrying value of the Ship Mortgage Notes (the
        "Notes") approximates fair value as of March 31, 1998 based upon similar
        financing terms and maturities. As of March 31, 1999, the value of the
        Notes was negatively affected causing the Notes to decline in value.
        However, due to the instability of the market and the elapsed time
        between the date of the consolidated balance sheet and the date of
        issuance of the Notes, the decline in value is deemed to be immaterial.

     ACCOUNTING ESTIMATES
     --------------------

     The preparation of the financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statement. When recorded, actual results could differ from such
     estimates. The most significant assumption and estimate relate to vessels
     under construction.

     INCOME TAXES
     ------------

     The Company is exempt from United States federal, state and local income
     taxes and has been granted exemptions from the statutory 20% tax on profits
     required to be assessed against Isle of Man companies.

     Certain entities are exempt from U.S. corporate income tax on U.S. source
     income from their international shipping operation if (i) their countries
     of incorporation exempt shipping operations U.S. persons from income tax
     (the "Incorporation Test") and (ii) they meet the "Ultimate Owners Test." A
     company meets the Ultimate Owners Test if more then 50% of the value of its
     stock is ultimately owned by individuals who are residents of a foreign
     country that exempts U.S. persons from tax on shipping earnings. The
     Company is involved in international shipping operations which meet the
     Incorporation Test because the Company is incorporated in the Isle of Man,
     which provides the required exemption to U.S. persons involved in shipping
     operations, and the Company believes more than 50% of the value of its
     outstanding shares is owned by individuals who are residents of countries
     which provide the required exemption to U.S. persons involved in shipping
     operations. The issue of residence is, however, inherently factual and
     cannot be determined.

     Based on the foregoing, the Company expects all of its income to remain
     exempt from United States income tax. Accordingly, no provision for taxes
     has been made in the financial statements.

     Nonmonetary Transactions
     ------------------------

     The transfer of nonmonetary assets to the Company by its shareholders in
     exchange for stock are recorded at the transferor's market value of
     services performed determined under generally accepted accounting
     principals.

3.   SHIP MORTGAGE NOTES:

     The Issuer placed, on August 7, 1997, through a private placement,
     $217,000,000 aggregate principal amount of 10 1/2% First Priority Ship
     Mortgage Notes Due 2007 (the "First Priority Notes") and together with
     Navigator Holdings PLC ("Holdings") placed 87,000 Units (the "Units"), each
     Unit consisting of one of the Company's 12% Second Priority Ship Mortgage
     Notes Due 2007 (a "Second Priority Note" and, together with the First
     Priority Notes, the "Notes") in a principal amount of $1,000 and 7.66
     Warrants (each a "Warrant"). The Notes are unconditionally and irrevocably
     guaranteed by each subsidiary of the Company (collectively, the
     "Guarantors"). The Notes will bear interest from August 7, 1997 (the "Issue
     Date") until the principal thereof is paid or made available for payment.
     Such interest will be payable semi-annually on June 30 and December 31 of
     each year, commencing December 31, 1997, to the person in whose name the
     relevant First Priority Notes or Second Priority Notes is registered at the
     close of business on the preceding June 15 or December 15.

     The Notes have priority of payment and are collateralized by (i) an
     assignment of each vessel; (ii) an assignment of the pre-funding account
     and capitalized interest account held by the Trustee (iii) an assignment of
     the Building Contracts and technical supervision agreement; (iv) an
     assignment of the commercial management agreement; (v) an assignment of the
     management agreement with a Company's affiliate; (vi) an assignment of the
     performance bonds; (vii) an assignment of the earnings and issuance
     proceeds related to each vessel and (viii) certain other collateral.

     DESCRIPTION OF WARRANTS
     -----------------------

     The Warrants have not been registered under the Securities Act and are
     subject to certain restrictions on transfer. Holders of the Warrants and
     the shares of Company Common Stock underlying the Warrants will have
     certain rights to require the Company to file and have declared effective a
     registration statement with respect thereto or to purchase such Warrants
     and underlying shares. The Warrants when exercised, will entitle the
     holders thereof to acquire an aggregated 666,420 shares of the Company's
     Common Stock, representing in aggregated 25% of the shares of the Company's
     Common Stock on a fully diluted basis. The Warrants will be reflected on
     the balance sheet as a reduction of the Second Priority Notes amortized
     over the life of the debt using the Effective Interest Method.

     ADDITIONAL NOTES
     ----------------

     cash available for distribution in the Revenue Account, as defined in the
     "Indenture Agreement", to the holder of the Second Priority Notes on such
     date is insufficient to pay all accrued and unpaid interest on the Second
     Priority Note, such interest may be paid through the issuance to the holder
     by the Issuer of additional Second Priority Notes having an aggregate
     principal amount equal to the deficiency in such available cash; provided
     further, however, that the Issuer may not issue more than $20.9 million in

CONSOLIDATED NOTES TO FINANCIAL STATEMENTS (CONTINUED)



     Other than as set forth in the previous paragraph, the First Priority Notes
     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

     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 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 (as defined in "Builders Performance Bond",
     dated August 7, 1997) 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 a 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 in the "Indenture
     Agreement", dated August 7, 1997), the 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 issuance proceeds with respect
     to such Total Loss and (b) 60 days after such Total Loss was deemed to have
     occurred.

     DEBT COVENANTS
     --------------

     The Notes include certain covenants that, among other things, limit the
     ability of the Issuer and the Owners to incur additional indebtedness, pay
     dividends or make certain payments, restrict distribution from Owners, sell
     assets, enter into certain mergers and consolidations, incur liens other
     than permitted liens and enter into certain transactions with affiliates.

     Letter of Credit
     ----------------

     The Issuer has entered into an Irrevocable Standby Letter of Credit
     Agreement (the "Agreement") with the Trustee and funding bank dated August
     7, 1997, for $50,000,000. The purpose of this Agreement is to provide
     securities for the holders of the mortgage notes regarding the repayment of
     principles and interest. The Agreement provides for two types of draws,
     interest draws and working capital draws. Under the terms of the Agreement,
     a maximum of $45,000,000 has been allocated for interest draws and
     $4,500,000 for working capital draws. The draws may only be used in certain
     increments and dates throughout the construction and post-delivery periods
     of the vessels, as defined in the Agreement. As of December 31, 1998, the
     issuer has no outstanding draws under the Agreement.

     Interest on the draws is charged at LIBOR plus one and one-quarter percent
     (1-1/4%) per annum.

     The Issuer is required under the Agreement to pay certain annual fees to
     sustain the Agreement. These fees are calculated at (1-1/4%) of the maximum
     available line of credit amount. These fees amount to $0 and $31,250 for
     the quarter ended March 31, 1999 and 1998, respectively, and have been
     included in other expenses on the Consolidated Statement of Operations. In
     addition, the funding bank has received an underwriting fee of $625,000 for
     the Agreement, which has been capitalized and will be amortized over the
     life of the mortgage notes.


4    RESTRICTED CASH:

     Restricted Cash is comprised of pre-funding and a capitalized interest
     account. These accounts were established in the name and under the control
     of the Trustee. The net proceeds of the Notes issued on behalf of the
     Company were deposited into the accounts in the form of a guaranteed
     investment contract. Restricted cash will be used primarily for the
     payments of interest and principal due on the Notes, management fees, and
     contract payments to the Builders for the construction of the vessels. At
     March 31, 1999 and 1998 the aggregate amount of Restricted Cash was
     $192,931,326 and $251,511,714, respectively.

5.   CONTINGENCIES AND COMMITMENTS:

     Future contractual payments to be made under the construction contracts for
     each of the succeeding year ending March 31, until completion are as
     follows:

                  ---------------------------------------

               exchange for services contributed to the Company during the
               pre-delivery period pursuant to the Technical Supervision
               Agreement dated August 7, 1997 and services contributed during
               the first six years of the operation under the Technical

          e)   Tractebel Gas Engineering GmbH ("TGE") was issued 200,000 shares

7.   RELATED PARTY TRANSACTIONS:

     On August 7, 1997, the following payments were disbursed to certain
     stockholders:

          a)   The amounts of $2.3 million and $2,273,696 were paid to a
               stockholder, CGTC, for structuring fees and costs of issuance of
               the Notes, respectively.

          b)   The amount of $2 million, $1 million to a stockholder, Xenon
               Shipping Inc., and $1 million to another stockholder, GEBAB, was
               paid for their services in developing charter contracts for the
               vessels during the pre-delivery period.


8.   CONCENTRATION OF CREDIT RISK:

     The Company has no sources for the payment of the principal of, and the
     interest on the Notes except for the pre-funding and capitalized interest
     accounts held by the Trustee. Accordingly, the Company's ability to pay
     debt service on the Notes is wholly dependent upon its financial condition,
     results of operations and cash flows when the vessels are in operation.

     The Company has five vessels under construction, all of which are being
     produced under contracts with one shipyard in the People's Republic of
     China ("PRC"). The production and delivery of these vessels is subject to
     the risk of nonperformance by the shipyard due to political or economic
     changes in the PRC, as well as interruption in sea or air transportation in
     the area. Although the Company has received various performance guarantees
     from the shipyard and its bank to recover its investment in the event of
     nonperformance, there can be no conclusive assurance that the
     counterparties will perform. Also, the Company's future shipping operations
     would be significantly disrupted if such event were to occur.


9.   MANAGEMENT AGREEMENTS:

     Each of the Owners entered into a Management Agreement with Navigator Gas
     Management Limited (an Isle of Man public limited company, the "Manager"),
     an affiliate of the Company. The Manager will manage their commercial and
     technical operations, including providing administrative services, causing

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.



                                      II-1

          Subject to the foregoing, an Isle of Man company 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

          (a) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrants pursuant to the foregoing provisions, or otherwise,
the registrants have 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
registrants of expenses incurred or paid by a director, officer or controlling
person of the registrants 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 registrants will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

          (b) The undersigned registrants hereby undertake:

                 (1) To file, during any period in which offers or sales are
being made, a post-effective amendment to this registration statement:

                        (i) To include any prospectus required by Section 10(a)
(3) of Securities Act of 1933;

                        (ii) To reflect in the prospectus any facts or events
arising after the effective date of the registration statement (or the most
recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the
registration statement; and

                        (iii) To include any material information with respect
to the plan of distribution not previously disclosed in the registration
statement or any material change to such information in the registration
statement.

                 (2) That, for the purpose of determining any liability under
the Securities Act of 1933, each such post-effective amendment shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

                 (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

                 (4) If the registrant is a foreign private issuer, to file a
post-effective amendment to the registration statement to include any financial
statements required by Rule 3-19 of this chapter at the start of any delayed
offering or throughout a continuous offering. Financial statements and
information otherwise required by Section 10(a)(3) of the Act need not be
furnished, provided, that the registrant includes in the prospectus, by means of
a post-effective amendment, financial statements required pursuant to this
paragraph and other information


                                      II-8
<PAGE>


necessary to ensure that all other information in the prospectus is at least as
current as the date of those financial statements.

          (c) The undersigned registrants hereby undertake as follows:

                 (1) That prior to any public or reoffering of the securities
registered hereunder through use of a prospectus which is a part of this
registration statement, by any person or party who is deemed to be an
underwriter within the meaning of Rule 145(c), the issuer undertakes that such
reoffering prospectus will contain the information called for by the applicable
registration form with respect to reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other items of
the applicable form.

                 (2) That every prospectus that is filed pursuant to the
paragraph immediately preceding or that purports to meet the requirements of
Section 10(a)(3) of the Act and is used in connection with an offering of
securities subject to Rule 415, will be filed as a part of an amendment to the
registration statement and will not be used until such amendment is effective,
and that, for purposes of determining any liability under the Securities Act of
1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

          (d) The undersigned registrants hereby undertake:

                 (1) To respond to requests for information that is incorporated
by reference into the Prospectus pursuant to Items 4, 10(b), 11 or 13 of Form
F-4, within one business day of receipt of such request, and to send the
incorporated documents by first class mail or other equally prompt means. This
includes information contained in documents filed subsequent to the effective
date of the Registration Statement through the date of responding to the
request; and

                 (2) To arrange to provide for a facility in the U.S. for the
purpose of responding to such requests. The undertaking in subparagraph (1)
above includes information contained in documents filed subsequent to the
effective date of the registration statement through the date of responding to
the request.

                             Dated: January 19, 1997


It has been mutually agreed between the Buyer and the Builder that
notwithstanding what has been previously agreed and for an additional cost of
US$ 100,000 per vessel, which will be added to the contract price and payable on
delivery of each vessel, the Specification has been amended as follows:

     1.   The specified salt water engine room machinery cooling system
          (including the air conditioning plant) will be replaced with a central
          flesh water cooling system. The central fresh water cooling system
          will consist of a short sea water cooling circuit (with 2 plate
          coolers in parallel) - cooling a long fresh water cooling circuit
          serving all machinery, coolers and heat exchangers in the engine room.
          The short sea water cooling circuit including all valves and fittings
          will be constructed of salt water resistant material such as cunife
          (except main sea water line which to be galvanised steel pipe) and the
          fresh water circuit of mild steel. All major coolers will be of plate
          type with plates constructed of titanium on the salt water cooling
          circuit and stainless steel on the fresh water circuit. The Builder
          will endeavour to install a plate cooler as the auxiliary condenser
          however if such plate condenser is not available the Builder will
          install a suitable tube cooler. The Builder will provide the Buyer
          with further details of the proposed arrangement for their approval.

     2.   The hull coating and cathodic protection system outlined in Section 3
          of the specification is amended so that it will comply with the
          requirements of Class for In Water Survey (IWS) and will provide that
          the vessel need only drydock every 5 years for Class renewal and
          recoating. Accordingly the Builder will provide an impressed current
          system and all other requirements to meet Class requirements.

     3    The Buyer will provide at his own expense a third compressor of 50% of
          the design capacity (125KW - 107,500 K.cal/hr) for the prescribed air
          conditioning system in the accommodation. At no additional cost to the
          Buyer, the Builder will install and arrange the three compressors in
          the engine room so that any two of the three compressors can run the
          system at any time with the third being in standby.
<PAGE>


     4.   In order to safely operate the remote control ballast system from the
          Cargo Control Room, the Builder will provide remote ballast pump start
          and stop controls and appropriate suction/pressure gauges at the
          ballast valve control station (mimic board).

     5.   The fuel oil transfer pumps prescribed in Section 7.10.3.1 shall be
          rearranged such that the diesel oil transfer pump will be of the same
          capacity as the heavy fuel oil transfer pump. In the event of the
          failure of either pump they will be interchangeable for either fuel
          system.

     6.   The Steam Generation Plant prescribed in Section 7.4 is amended to a
          smoke tube composite boiler manufactured by Shazhou Boiler Works in
          co-operation with Saake. The Builder will provide the Buyer with
          detailed drawings of the amended arrangement for approval. As the
          composite boiler is now smoke tube type on both sides, the soot blower
          prescribed in Section 7.4.2.4 is deleted.

     7.   Section 8.2 - Main Diesel generators - it is agreed that the structure
          and number of bearings will be as per manufacturers standard.

               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 Old
First Priority Notes indicated above. Subject to, and effective upon, the
acceptance for exchange of such Old 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 Old 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 Old Priority Notes Exchange Agent the true and
lawful agent and attorney-in-fact of the undersigned (with full knowledge that
said Old Priority Notes Exchange Agent acts as the agent of the Companies in
connection with the Exchange Offer) to cause the Old 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 Old First Priority Notes and to acquire New First Priority Notes issuable
upon the exchange of such tendered Old First Priority Notes, and that when the
same are accepted for exchange, the Companies will acquire good and unencumbered
title to the tendered Old 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 New First Priority Notes issued
in exchange for the Old 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 Old 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 New 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 New First
Priority Notes and have no arrangement or understanding with any person to
participate in a distribution of New First Priority Notes.

     By signing or electronically confirming this Letter of Transmittal, the
undersigned represents to the Companies that (i) the New 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 New First Priority Notes and
has no arrangement or understanding with any person to participate in a
distribution of the New 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 Old 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 New First Priority
Notes for its own account in exchange for Old First Priority Notes, it
represents that the Old First Priority Notes to be exchanged for the New First
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 New 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 Old Priority Notes Exchange Agent
or the Companies to be necessary or desirable to complete the exchange,
assignment and transfer of tendered Old First Priority Notes or transfer
ownership of such Old 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 "Conditions to the Exchange Offer." 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 Old First Priority
Notes tendered hereby and, in such event, the Old 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 Old First Priority Notes may be
withdrawn at any time prior to the Expiration Date.

                                  INSTRUCTIONS

         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

1.   DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES.

     All physically delivered Old 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 Old 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 OF DELIVERY OF THIS LETTER OF
TRANSMITTAL, THE OLD FIRST PRIORITY NOTES AND ANY OTHER REQUIRED DOCUMENTS,
INCLUDING DELIVERY THROUGH BOOK ENTRY TRANSFER, IS AT THE ELECTION AND RISK OF
THE HOLDER AND, EXCEPT AS OTHERWISE PROVIDED BELOW, 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 Old First Priority Notes and who do not
hold their Old First Priority Notes through a book-entry transfer facility, but
whose Old First Priority Notes are not immediately available or who cannot
deliver their Old 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
               Old First Priority Notes and the principal amount of Old 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 Old First Priority Notes (or a confirmation of
               book-entry transfer of such Old First Priority Notes into the
               First 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 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 Old First Priority Notes in proper form for transfer
               (or a confirmation of book-entry transfer of such Old 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 Old First
Priority Notes according to the guaranteed delivery procedures set forth above.
Any Holder who wishes to tender Old First Priority Notes pursuant to the
guaranteed delivery procedures described above must


                                      10
<PAGE>

ensure that the First Priority Notes Exchange Agent receives the Notice of
Guaranteed Delivery relating to such Old 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 Old 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 Old First Priority Notes Tendered
Hereby." A newly issued Old Note for the principal amount of Old 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 New First Priority Notes is offered in exchange for each $1,000
principal amount of Old First Priority Notes. All Old First Priority Notes
delivered to the First Priority Notes Exchange Agent will be deemed to have been
tendered in full unless otherwise indicated.

     Old 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 Old 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 system for
DTC participants) must be timely received by the First Priority Notes Exchange
Agent. Any such notice of withdrawal must (i) specify the name of the person
having deposited the Old First Priority Notes to be withdrawn (the "Depositor"),
(ii) identify the Old First Priority Notes to be withdrawn (including the
registration number(s) and principal amount of such Old First Priority Notes or,
in the case of Old 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 Old First Priority Notes
register the transfer of such Old First Priority Notes into the name of the
person withdrawing the tender and (iv) specify the name in which any such Old
First Priority Notes are to be registered, if different from that of the
Depositor. If Old 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 Old First Priority Notes so withdrawn will be deemed not to have
been validly tendered for purposes of the Exchange Offer and no New First
Priority Notes will be issued with respect thereto unless the Old First Priority
Notes so withdrawn are validly retendered. Any Old 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 Old 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
Old 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
Old First Priority Notes.

     If any of the Old 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 Old 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 Old
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 Old 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 Old First 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 Old First Priority Notes)
listed and tendered hereby, no endorsements of the tendered Old First Priority
Notes or separate written instruments of transfer or exchange are required. In
any other case, the registered Holder (or


                                       11
<PAGE>

acting Holder) must either properly endorse the Old 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 Old 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 Old First Priority Notes, exactly as the name of the
participant appears on such security position listing), with the signature on
the Old First Priority Notes or bond power guaranteed by an Eligible Institution
(except where the Old 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 New First
Priority Notes or substitute Old 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 New First Priority Notes (and any Old
First Priority Notes not tendered or not accepted) will be issued in the name of
and sent to the acting Holder of the Old 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 Old First Priority Notes pursuant to the Exchange
Offer. If, however, certificates representing the New First Priority Notes or
the Old 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 Old First Priority Notes tendered, or if
tendered Old 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 Old 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 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 Old First 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 Old 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, 750 Lexington Avenue, 30th Floor, New York, New
York, 10022, telephone number: (212) 527-2525.

10.  VALIDITY AND FORM.

     All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Old First Priority Notes and withdrawal of
tendered Old First Priority Notes will be determined by Navigator Gas Transport
in its sole


                                       12
<PAGE>

discretion, which determination will be final and binding. Navigator Gas
Transport reserves the absolute right to reject any and all Old First Priority
Notes not properly tendered or any Old 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 Old 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 Old 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 Old 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 Old First
Priority Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived. Any Old 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 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 Old First Priority Notes
is required to provide the First Priority Notes Exchange Agent with such
Holder's correct TIN on Substitute Form W-9 above. 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 Old 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 Old 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 Old First Priority Notes. If Old 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 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.

               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 Old
Second Priority Notes indicated above. Subject to, and effective upon, the
acceptance for exchange of such Old 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 Old 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 Old 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 Old Second Priority Notes and to acquire New Second Priority Notes issuable
upon the exchange of such tendered Old Second Priority Notes, and that when the
same are accepted for exchange, the Companies will acquire good and unencumbered
title to the tendered Old 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 New Second Priority Notes issued
in exchange for the Old 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 Old 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 New 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 New Second
Priority Notes and have no arrangement or understanding with any person to
participate in a distribution of New Second Priority Notes.

     By signing or electronically confirming this Letter of Transmittal, the
undersigned represents to the Companies that (i) the New 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 New Second Priority Notes
and has no arrangement or understanding with any person to participate in a
distribution of the New 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 Old Second 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 Second
Priority Notes for its own account in exchange for Old Second Priority Notes, it
represents that the Old Second Priority Notes to be exchanged for the New 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 New 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 Old Second Priority Notes or transfer
ownership of such Old 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 "Conditions to the Exchange Offer." 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 Old Second Priority
Notes tendered hereby and, in such event, the Old 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 Old Second Priority Notes may be
withdrawn at any time prior to the Expiration Date.

Priority Notes Exchange Agent receives the Notice of Guaranteed Delivery
relating to such Old Second Priority Notes prior to the Expiration Date. Failure
to complete the guaranteed delivery procedures outlined above will not, of


                                       10
<PAGE>

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 Old 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 Old Second Priority Notes Tendered
Hereby." A newly issued Old Note for the principal amount of Old 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 New Second Priority Notes is offered in exchange for each $1,000
principal amount of Old Second Priority Notes. All Old Second Priority Notes
delivered to the Second Priority Notes Exchange Agent will be deemed to have
been tendered in full unless otherwise indicated.

     Old 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 Old 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 system for
DTC participants) 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 Old Second Priority Notes to be withdrawn (the
"Depositor"), (ii) identify the Old Second Priority Notes to be withdrawn
(including the registration number(s) and principal amount of such Old Second
Priority Notes or, in the case of Old 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 Old
Second Priority Notes register the transfer of such Old Second Priority Notes
into the name of the person withdrawing the tender and (iv) specify the name in
which any such Old Second Priority Notes are to be registered, if different from
that of the Depositor. If Old 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
Navigator Gas Transport, whose determination shall be final and binding on all
parties. Any Old Second Priority Notes so withdrawn will be deemed not to have
been validly tendered for purposes of the Exchange Offer and no New Second
Priority Notes will be issued with respect thereto unless the Old Second
Priority Notes so withdrawn are validly retendered. Any Old 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 Old 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
Old 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
Old Second Priority Notes.

     If any of the Old 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 Old 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 Old
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 Old 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.

     If this Letter of Transmittal is signed by the registered Holder or Holders
of Old 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 Old Second Priority Notes)
listed and tendered hereby, no endorsements of the tendered Old 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 Old Second Priority Notes or transmit properly completed


                                       11
<PAGE>

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 Old 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 Old Second
Priority Notes, exactly as the name of the participant appears on such security
position listing), with the signature on the Old Second Priority Notes or bond
power guaranteed by an Eligible Institution (except where the Old 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 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 New Second
Priority Notes or substitute Old 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 New Second Priority Notes (and any Old
Second Priority Notes not tendered or not accepted) will be issued in the name
of and sent to the acting Holder of the Old 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 Old Second Priority Notes pursuant to the Exchange
Offer. If, however, certificates representing the New Second Priority Notes or
the Old 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 Old Second Priority Notes tendered, or
if tendered Old 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 Old 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 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 Old 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 Old 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, 750 Lexington Avenue, 30th Floor,
New York, New York, 10022, telephone number: (212) 527-2525.

10.  VALIDITY AND FORM.

     All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Old Second Priority Notes and withdrawal of
tendered Old 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 Old Second
Priority Notes not properly tendered or any Old Second Priority Notes the
acceptance of which would, in


                                       12
<PAGE>

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 Old 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 Old 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 Old 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 Old Second Priority
Notes will not be deemed to have been made until such defects or irregularities
have been cured or waived. Any Old Second Priority Notes received by the Second
Priority Notes Exchange Agent that are not properly tendered and as to which the
defects or irregularities have not been cured or waived will be returned by the
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 Old 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 Old 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 Old 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 Old Second Priority Notes. If Old 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, 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 OLD 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.
