                          (ii) an amount equal to the product of (x) the
                  difference between (1) the amount set forth on Schedule 2
                  hereto calculated as of the first day of the calendar month
                  immediately succeeding the month in which the Date of
                  Rejection occurs and (2) the amount set forth on Schedule 2
                  hereto as of the first day of the month in which the Date of
                  Rejection occurs and (y) a fraction the numerator of which is
                  the numeric day of the month of the Date of Rejection and the
                  denominator of which is 30, and

                          (iii) an amount equal to the product of (x) the
                  difference between (1) the amount set forth on Schedule 3

                  denominator of which is 30.

If the amount as calculated above is not paid on the Date of Rejection there
shall be added to such amount interest at the rate of ten percent (10%) per
annum from and including the Date of Rejection to but not including the date
such amount is paid. Such refunds by the SELLER to the BUYER shall forthwith
discharge all obligations, duties, and liabilities of each of the parties hereto
to the other under this Contract. Any and all refunds made to the BUYER under
this Article II, Section 7 shall be made in United States Dollars. Throughout
this Contract, whenever interest is due on any amounts to be paid or refunded by
either party, said interest shall be calculated as simple interest, based on the
actual number of days divided by 360.

        For purposes of this Section 7(a) Date of Rejection means the date on
which written notice of rejection, cancellation or rescission is delivered by
BUYER to SELLER.

        All refunds made by the SELLER to the BUYER under this contract shall be
paid in United States Dollars by telegraphic transfer to the BUYER's account or

        The Contract Price of the VESSEL as provided for in Schedule 1 shall be
subject to adjustments as hereinafter set forth. It is hereby understood by both
parties that any reduction of the Contract Price is by way of liquidated damages
and not by way of penalty.

1.      DELIVERY

        (a)       Delayed Delivery Price Adjustment:

                          (i) For purposes of this Contract the Original
                  Delivery Date for the Vessel shall mean the date set forth in
                  Article VII, Section (1) below.

                          (ii) If the Delivery is not made on the Original
                  Delivery Date (subject to a Permissible Delay as defined
                  below), the SELLER shall pay the BUYER, as liquidated damages
                  (not as penalty), the amount of $10,000 for each calendar day
                  for the first ninety (90) calendar days of delay beyond the
                  Extended Delivery Date (as hereinafter defined) and the amount
                  of $13,500 for each calendar day of delay thereafter up to and
                  including the 210th day from the Original Delivery Date
                  ("Original Delay

                                                     Shipbuilding Contract H2245

                  Period"). Liquidated damages calculated with respect to the
                  Original Delay Period shall be recovered by the BUYER through
                  a reduction in the Fifth Installment payable by the BUYER to
                  the SELLER in an amount equal to such Liquidated Damages.

                          (iii) If delivery of the VESSEL is delayed for any
                  reason beyond the Original Delay Period, the Builder may elect
                  to further postpone delivery of the Vessel beyond the Original
                  Delay Period until March 31, 2001 provided SELLER pays
                  liquidated damages monthly in advance to the BUYER at the rate
                  of US$18,000 per day from the end of the Original Delay Period
                  to a date which is 6 months thereafter (the "First Penalty
                  Date"), and US$20,000 per day from the First Penalty Date to
                  the date which is 6 months thereafter (the "Second Penalty
                  Date"), and US$22,000 per day from the Second Penalty Date
                  until March 31, 2001. If the SELLER fails to make any
                  liquidated damages payment, BUYER, in its sole discretion, may
                  either (i) reject the VESSEL or (ii) waive its right to
                  receive the payment of liquidated damages and further reduce
                  the Contract Price for the VESSEL by an amount equal to the
                  liquidated damages which would have been payable.
                  Notwithstanding any other provision contained in this Contract
                  to the contrary, this Contract shall be deemed rescinded on
                  April 1, 2001 and the Buyer shall be entitled to receive the
                  amounts set forth in Article II, Section 7(a) above.

                          Any waiver by the BUYER of its right to receive
                  liquidated damages monthly in advance is not a waiver of the
                  BUYER's right to (a) demand payment of such liquidated damages
                  at a later date, (b) demand monthly advances as to Liquidated
                  Damages for any subsequent months of delay or (c) reject the
                  VESSEL at such later date if liquidated damages are not paid
                  upon demand. The liquidated damages calculated pursuant to
                  this paragraph are in addition to the reduction in the fifth
                  installment of the Contract Price as calculated pursuant to
                  (ii) above for the Original Delay Period.

                          (iv) In the event that the BUYER elects to reject the
                  VESSEL as allowed under this Article III, Section 1(a), the
                  SELLER shall immediately repay to the BUYER the amounts set
                  forth in Article II, Section 7, whereupon this Contract shall
                  terminate and such payment shall forthwith discharge all
                  obligations, duties and liabilities of each party hereto to
                  the other under this Contract.

                  the VESSEL shall not be deemed delayed and the Contract Price
                  shall not be reduced when and if the Original Delivery Date of
                  the VESSEL is extended by reason of a Permissible Delay. For
                  purposes of this Article a Permissible Delay means a delay

                  (2) Article VIII, and (3) any delay caused by any action or
                  inaction on the part of SELLER; provided such Permissible
                  Delay shall be subject to the following provisions:

                                            (iv)    Hull No. 2248 - 30 days
                                            (v)     Hull No. 2249 - 30 days

                                   (B) For purposes of this Contract the
                          Extended Delivery Date for a Vessel shall mean the
                          Original Delivery Date plus the Permissible Delay for
                          such Vessel,

                                   (C)  The aggregated Permissible Delay for the
                          Vessel and the Sister Vessels shall not exceed 150 
                          days, and

                                   (D) Subject to the limitations set forth in
                          (A) above, SELLER shall have the right in its sole
                          discretion to designate either the Vessel or any
                          Sister Vessel as to which Vessel will be subject to a
                          Permissible Delay.

        (b)       Early Delivery Price Adjustment:

                          If the SELLER notifies the BUYER by facsimile that the
                  delivery of the VESSEL shall be made earlier than the Original
                  Delivery Date and such notification is given not less than two

                  amount of bonus shall be given by the BUYER to the SELLER as

                          In the event that the delivery shall be made earlier
                  than the Original Delivery Date and notice is properly given,
                  then a bonus shall be added to the Contract Price at a rate of
                  United States Dollars Thirteen Thousand (US$13,000) per day
                  for each full day earlier than the Original Delivery Date.

                          The total increase of the Contract Price for the
                  earlier delivery shall be added to the fifth installment of

        The parties hereto shall, within a reasonable period of time after
signing of this Contract, mutually agree upon a list of all the plans and
drawings, which are to be sent to the BUYER for approval (hereinbelow called
"the LIST"). Before the arrival of the Supervisor at the BUILDER's Shipyard, the
plans and drawings specified in the LIST shall be sent to the BUYER, and the
BUYER shall, within fourteen (14) days after receipt thereof (excluding mailing
time), return such plans and drawings submitted by the SELLER with approval or
remarks, if any.

        Concurrently with the arrival of the Supervisor at the BUILDER's
Shipyard, the BUYER shall notify the BUILDER, in writing, of the authority the
Supervisor shall have with regard to the approval or modification of plans and
drawings (that is, which of the drawing and plans specified in the LIST but not
yet sent to the BUYER can be submitted to and approved by the Supervisor).
Nevertheless in line with the Supervisor's authority, the Supervisor shall,
within five (5) days after receipt thereof, return those submitted plans and
drawings with approval or remarks, if any.

        Unless notification is given to the BUILDER by the Supervisor or the
BUYER of approval or disapproval of any plans and drawings within the above
designated period of time for each case, the said plans and drawings shall be
deemed to have been automatically approved.

                                                     Shipbuilding Contract H2245

        The plans and drawings approved by the BUYER or Supervisor shall be
final, and any alteration thereof shall be regarded as modification specified in
Article V of this Contract.

3.      SUPERVISION AND INSPECTION BY THE SUPERVISOR

        The necessary inspection of the VESSEL, its machinery, equipment and
outfittings shall be carried out by the Classification Society, and/or
inspection team of the BUILDER throughout the entire period of construction in
order to ensure that the construction of the VESSEL is duly performed in
accordance with the Contract and Specifications.

        The Supervisor shall have, at all times until delivery of the VESSEL,
the right to attend tests according to the mutually agreed test list and inspect
the VESSEL, her engines, accessories and materials at the BUILDER's Shipyard,
its subcontractors or any other place where work is done or materials stored in
connection with the VESSEL. In the event that the Supervisor discovers any
construction or material or workmanship which does not or will not conform to
the requirements of this Contract and the Specifications, the Supervisor shall
promptly give the BUILDER a notice in writing as to such nonconformity, upon
receipt of which the BUILDER shall correct such nonconformity if the BUILDER
agrees with the BUYER. However the BUYER undertakes and assures the SELLER that
the Supervisor shall carry out his inspections in accordance with the agreed
inspection procedure and Schedule and usual shipbuilding practice and in a way
as to minimize any increase in building costs and delays in the construction of
the VESSEL.

        The BUILDER agrees to furnish, free of charge, the Supervisor with
office space, and other reasonable facilities according to BUILDER's practice
at, or in the immediate vicinity of the BUILDER's Shipyard, but the fees for the
international communication like telephone and telefax, etc. shall be borne by
the BUYER. At all times, during the construction of the VESSEL until delivery
thereof, the Supervisor shall be given free and ready access to the VESSEL, her
engines and accessories, and to any other place where the work is being done, or
the materials are being processed or stored, in connection with the construction
of the VESSEL, including the yards, workshops, stores of the BUILDER, and the
premises of subcontractors of the BUILDER, who are doing work, or storing
materials in connection with the VESSEL's construction. The travel expenses for
the said access to SELLER's subcontractors outside of Shanghai shall be at
BUYER's account. The transportation within Shanghai shall be provided to the
Supervisor by the SELLER.

4.      LIABILITY OF THE SELLER

        The Supervisor engaged by the BUYER under this Contract shall at all
times be deemed to be in the employment of the BUYER. The SELLER shall be under
no liability whatsoever to the BUYER, or to the Supervisor or the BUYER's
employees or agents for personal injuries, including death, during the time when
they, or any of them, are on the VESSEL, or within the premises of either the
SELLER or its subcontractors, or are otherwise engaged in and about the
construction of the VESSEL, unless, however, such personal injuries, including
death, were caused by negligence of the SELLER, or of any of the SELLER's
employees or agents or subcontractors of the SELLER. Nor shall the SELLER be
under any liability whatsoever to the BUYER for damage to, or loss or
destruction of property in China of the BUYER or of the Supervisor, or of the
BUYER's employees or agents, unless such damage, loss or destruction was caused
by negligence of the SELLER, or of any of the employees, or agents or
subcontractors of the SELLER.

5.      SALARIES AND EXPENSES

        All salaries and expenses of the Supervisor, or any other employees
employed by the BUYER under this Article, shall be for the BUYER's account.

6.      REPLACEMENT OF SUPERVISOR

        The SELLER has the right to request the BUYER in writing to replace any
of the Supervisor who is deemed unsuitable and unsatisfactory for the proper
progress of the VESSEL's construction together with reasons. The BUYER shall
investigate the situation by sending its representative to the BUILDER's yard,
if necessary, and if the BUYER considers that such SELLER's request is
justified, the BUYER shall effect the replacement as soon as conveniently
arrangable.

                                    ARTICLE V
                        MODIFICATION, CHANGES AND EXTRAS

1.      HOW EFFECTED

        The Specifications in accordance with which the VESSEL is constructed,
may be modified and/or changed at any time hereafter by written agreement of the
parties hereto, provided that such modifications and/or changes or an
accumulation thereof will not, in the BUILDER's reasonable judgment, adversely
affect the BUILDER's other commitments and provided further that the BUYER shall
assent to adjustment of the Contract Price, time of delivery of the VESSEL and
other terms of this Contract, if any, as hereinafter provided. Subject to the
above, the SELLER hereby agree to exert their best efforts to accommodate such
reasonable requests by the BUYER so that the said changes and/or modifications
may be made at a reasonable cost and within the shortest period of time which is
reasonable and possible. Any such agreement for modifications and/or changes
shall include an agreement as to the increase or decrease, if any, in the
Contract Price of the VESSEL together with an agreement as to any extension or
reduction in the time of delivery, providing to the SELLER additional securities
satisfactory to the SELLER, or any other alterations in this Contract, or the
Specifications occasioned by such modifications and/or changes. The
aforementioned agreement to modify and/or to change the Specifications may be
effected by an exchange of duly authenticated letters, telex and telefaxes,
manifesting such agreement. The letters, telexes as well as telefaxes exchanged
by the parties hereto pursuant to the foregoing shall constitute an amendment of
the Specifications under which the VESSEL shall be built, and such letters,
telexes and telefaxes shall be deemed to be incorporated into this Contract and
the Specifications by reference and

                                      -19-




                                                       Amended and Restated
                                                     Shipbuilding Contract H2245

made a part hereof. Upon consummation of the agreement to modify and/or to
change the Specifications, the SELLER shall alter the construction of the VESSEL
in accordance therewith, including any additions to, or deductions from, the
work to be performed in connection with such construction. If due to whatever
reasons, the parties hereto shall fail to agree on the adjustment of the
Contract Price or extension of time of delivery or providing additional security
to the SELLER or modification of any terms of this Contract which are
necessitated by such modifications and/or changes, then the SELLER shall have no
obligation to comply with the BUYER's request for any modification and/or
changes.

2.      CHANGES IN RULES AND REGULATIONS

        (a) If, after the Effective Date, any requirements as to the rules and
regulations as specified in this Contract and the Specifications to which the
construction of the VESSEL is required to conform, are altered or changed by the
Classification Society or the other regulatory bodies authorized to make such
alterations or changes, the SELLER and/or the BUYER, upon receipt of the notice
thereof, shall transmit such information in full to each other in writing,
whereupon within twenty one (21) days after receipt of the said notice by the
BUYER from the SELLER or vice versa, the BUYER shall instruct the SELLER in
writing as to the alterations or changes, if any, to be made in the VESSEL which
the BUYER, in its sole discretion, shall decide. The SELLER shall promptly
comply with such alterations or changes, if any in the construction of the
VESSEL, provided that the BUYER shall first agree:

                  (i) As to any increase or decrease in the guaranteed
        deadweight and/or cargo tank capacity and for speed of the VESSEL, if
        such compliance results in increased or reduced deadweight and/or cargo
        tank capacity and speed; and/or

                  (ii) As to any other alterations in the terms of this Contract
        or of Specifications or both, if such compliance makes such alterations
        of the terms necessary.

        Agreement as to such alterations or changes under this Paragraph shall
be made in the same manner as provided above for modifications and/or changes of
the Specifications and/or Plans.

        (b)       If, due to whatever reasons, the parties shall fail to agree
on the increase or decrease of the guaranteed speed, deadweight and cargo tank
capacity,

                                      -20-




                                                       Amended and Restated
                                                     Shipbuilding Contract H2245

or any alteration of the terms of this Contract, if any, then the SELLER shall
be entitled to proceed with the construction of the VESSEL in accordance with,
and the BUYER shall continue to be bound by, the terms of this Contract and
Specifications without making any such alterations or changes.

        (c) The BUYER and the SELLER hereby agree to make best efforts to avoid
the application and/or minimize the effect of any change in the rules and
regulations of the Classification Society as to the Specifications. If the BUYER
and the SELLER are unsuccessful in avoiding the application of such change in
rules and regulations, then the SELLER shall effect any modifications and/or
changes in Specifications without adjustment to the Contract Price and the BUYER
shall grant to the SELLER the right to extend the Delivery Date (if necessary)
for a maximum period of up to twelve (12) days.

3.      SUBSTITUTION OF MATERIALS AND/OR EQUIPMENT

        In the event that any of the materials and/or equipment required by the
Specifications or otherwise under this Contract for the construction of the
VESSEL cannot be procured in time to effect delivery of the VESSEL, the SELLER
may, provided the SELLER shall provide adequate evidence and the BUYER so agrees
in writing, supply other materials and/or equipment of the equivalent quality,
capable of meeting the requirements of the Classification Society and of the
rules, regulations, requirements and recommendations with which the construction
of the VESSEL must comply.

4.      BUYER'S SUPPLIED ITEMS

        The BUYER shall deliver to the SELLER at its shipyard the items as
specified in the Specifications which the BUYER shall supply for its own account
(the "BUYER's Supplies") by the time designated by the SELLER.

        The delay in the delivery or the failure to deliver by the BUYER of any
BUYER's Supplies within the time specified shall not extend the Delivery Date.

        However, if the delay in delivery of the BUYER's Supplies should exceed
fifteen (15) days, the SELLER shall be entitled to proceed with construction of
the VESSEL without installation of such items in or onto the VESSEL and the
BUYER shall accept the VESSEL so completed.


                                      -21-




                                                       Amended and Restated
                                                     Shipbuilding Contract H2245

        The BUILDER shall be responsible for storing and handling of the BUYER's
Supplies as specified in the Specifications after delivery to the BUILDER and
shall install them on board the VESSEL at the BUILDER's expenses.

        Upon arrival of such shipment of the BUYER's Supplies, both parties
shall undertake an joint unpacking inspection. If any damaged BUYER's supplies
are found to be unsuitable for installation, the BUILDER shall be entitled to
refuse to accept the BUYER's Supplies.

                                   ARTICLE VI
                                     TRIALS

1.      NOTICE

        The BUYER and the Supervisor shall receive from the SELLER at least
thirty (30) days notice in advance and seven (7) days definite notice in advance
in writing by telex or telefax, of the time and place of the VESSEL's sea trial
as described in the Specifications (hereinafter referred to as "the Trial Run")
and the BUYER and the Supervisor shall promptly acknowledge receipt of such
notice. The BUYER's representatives and/or the Supervisor shall be on board the
VESSEL to witness such Trial Run, and to check upon the performance of the
VESSEL during the same. Failure of the BUYER's representatives to be present at
the Trial Run of the VESSEL, after due notice to the BUYER and the Supervisor as
provided above, shall have the effect to extend the date for delivery of the
VESSEL by the period of delay caused by such failure to be present. However, if
the Trial Run is delayed more than five (5) days by reason of the failure of the
BUYER's representatives to be present after receipt of due notice as provided
above (other than due to the failure by the BUYER's representative to obtain a
visa to enter China), then in such event, the BUYER shall be deemed to have
waived its right to have its representatives on board the VESSEL during the
Trial Run, and the BUILDER may conduct such Trial Run without the BUYER's
representatives being present, and in such case the BUYER shall be obliged to
accept the VESSEL on the basis of a certificate jointly signed by the BUILDER
and the Classification Society certifying that the VESSEL, after Trial Run
subject to minor alterations and corrections as provided in this Article, if
any, is found to conform to the Contract and Specifications and is satisfactory
in all respects. The SELLER hereby warrants that the necessary visa for the
BUYER's representatives to enter China will be issued in order on demand and
without delay otherwise the Trial Run shall be postponed until the BUYER's
representatives have arrived at the BUILDER's Shipyard. However, should the
nationalities and other personal particulars of the BUYER's representatives be
not acceptable to the SELLER in accordance with its best understanding of the
relevant

                                      -22-




                                                       Amended and Restated
                                                     Shipbuilding Contract H2245

rules, regulations and/or Laws of the People's Republic of China then
prevailing, then the SELLER shall so notify the BUYER and the BUYER shall
endeavor to effect the replacement of all or any of such representatives. The
Delivery Date as stipulated in Article VII hereof shall not be extended by any
delays caused by the BUYER's replacement of its representatives pursuant to the
SELLER's request. In the event of unfavorable weather on the date scheduled for
the Trial Run, the same shall take place on the first available day thereafter
that the weather conditions permit. The parties hereto recognize that the
weather conditions in Chinese waters in which the Trial Run is to take place are
such that great changes in weather may arise momentarily and without warning
and, therefore, it is agreed that if during the Trial Run of the VESSEL, the
weather should suddenly become unfavorable, as would have precluded the
continuance of the Trial Run, the Trial Run of the VESSEL shall be discontinued
and postponed until the first favorable day next following, unless the BUYER
assents in writing by telex or telefax of its acceptance of the VESSEL on the
basis of the Trial Run made prior to such sudden change in weather conditions.
In the event that the Trial Run is postponed because of unfavorable weather
conditions, the Delivery Date shall not be extended other than pursuant to
Article VIII hereof.

2.      HOW CONDUCTED

        (a) All expenses in connection with Trial Run of the VESSEL are to be
for the account of the BUILDER, who, during the Trial Run and when subjecting
the VESSEL to Trial Run, is to provide, at its own expense, the necessary crew
to comply with conditions of safe navigation. The Trial Run shall be conducted
in the manner prescribed in the Specifications and shall prove fulfillment of
the performance required for the Trial Run as set forth in the Specifications.

        The course of Trial Run shall be determined by the BUILDER and shall be
conducted within the trial waters equipped with speed measuring facilities.

        (b) The BUILDER shall provide the VESSEL with the required quantities of
water and fuel oil with exception of lubrication oil, hydraulic oil and greases
which shall be supplied by the BUYER according to the BUILDER's schedule which
shall be forwarded to the BUYER by the BUILDER for the conduct of the Trial Run
or Trial Runs as prescribed in the Specifications. The fuel oil supplied by the
SELLER, and lubricating oil, hydraulic oil and greases supplied by the BUYER
shall be in accordance with the applicable engine Specifications, and the cost
of the quantities of water, fuel oil, lubricating oil, hydraulic oil and greases
consumed during the Trial Run or Trial Runs shall be for the account of the
BUILDER.

3.      TRIAL LOAD DRAFT

        In addition to the supplies provided by the BUYER in accordance with
sub-paragraph (b) of the preceding Section 2 of this Article VI, the BUILDER
shall provide the VESSEL with the required quantity of fresh water and other
stores necessary for the conduct of the Trial Run. The necessary ballast (fresh
water, sea water or any other ballast as may be required) to bring the VESSEL to
the trial load draft as specified in the Specifications, shall be for the
BUILDER's account.

4.      METHOD OF ACCEPTANCE OR REJECTION

        (a) Upon notification of the BUILDER of the completion of the Trial Run
of the VESSEL attached with the trial result, the BUYER or the BUYER's
Supervisor shall within six (6) business days thereafter, notify the BUILDER in
writing by telex or telefax of its acceptance of the VESSEL or of its rejection
of the VESSEL together with the reasons therefor.

        (b) However, should the result of the Trial Run indicate that the VESSEL
or any part thereof including its equipment does not conform to the requirements
of this Contract and Specifications the BUILDER shall investigate with the
Supervisor the cause of failure and shall take proper steps to remedy the same
and shall make whatever corrections and alterations and/or re-Trial Run or Trial
Runs as may be necessary without extra cost to the BUYER, and upon notification
by the BUILDER of completion of such alterations or corrections and/or re-trial
or re-trials, the BUYER shall, within six (6) business days thereafter, notify
the SELLER in writing by telex or telefax of its acceptance of the VESSEL or of
its rejection of the VESSEL together with the reason therefor on the basis of
the alterations and corrections and/or re-Trial Run or re-Trial Runs by the
BUILDER.

        (c) In the event that the BUYER fails to notify the SELLER in writing by
telex or telefax of its acceptance or rejection of the VESSEL together with the
reason therefor within six (6) business days period as provided for in the above
sub-paragraphs (a) and (b), the BUYER shall be deemed to have accepted the
VESSEL.

        (d) Any dispute arising among the parties hereto as to the result of any
Trial Run or further tests or trials, as the case, may be, of the VESSEL shall
be referred to the Classification Society as provided in Article XIII Section 2
hereof.

        (e) Nothing herein shall preclude the BUYER from accepting the VESSEL
with its qualifications and/or remarks following the Trial Run and/or further
tests or trials as

                                      -24-

                                                     Shipbuilding Contract H2245

aforesaid and the SELLER shall be obliged to comply with and/or remove such
qualifications and/or remarks (if such qualifications and/or remarks are
acceptable to the SELLER) at the time before effecting delivery of the VESSEL to
the BUYER under this Contract.

5.      DISPOSITION OF SURPLUS CONSUMABLE STORES

        Should any amount of fuel oil, fresh water, or other unbroached
consumable stores furnished by the BUILDER for the Trial Run or Trial Runs
remain on board the VESSEL at the time of acceptance thereof by the BUYER, the
BUYER agrees to buy the same from the SELLER at the purchasing price at the port
of delivery thereof, and payment by the BUYER shall be effected, together with
the payment of the fifth installment, as provided in Article II, Section 4 of
this Contract.

        The BUYER shall supply lubricating oil, hydraulic oil and greases for
the purpose of Trial Runs at its own expenses and the SELLER will reimburse for

the said Trial Run or Trial Runs at the purchasing price incurred by the BUYER
and payment by the SELLER shall be effected by deducting from the fifth
installment the amount of such payment as provided in Article II, Section 4 of
this Contract.

6.      EFFECT OF ACCEPTANCE

        The BUYER's acceptance of the VESSEL in writing by telex or telefax
notification sent to the SELLER, in accordance with the provisions set out
above, shall be final and binding so far as conformity of the VESSEL to this
Contract and the Specifications is concerned, and shall preclude the BUYER from
refusing Delivery (as defined below) by the SELLER of the VESSEL, as hereinafter
provided, if the SELLER complies with all other procedural requirements for
delivery as hereinafter set forth.

                                   ARTICLE VII

Supplier. The Supplier shall give qualified guidance, instruction and
consultations with regard to the gas trial, all of which shall be arranged by
the SELLER under the terms of its contract with the Supplier. The SELLER shall
at its own expense dispatch its representative(s) to attend such gas trial as
witness. The BUYER shall give the SELLER twenty (20) days advance notice in
connection with the time and place for such trial. The gas trial shall be made
latest forty-five (45) days after delivery of the VESSEL (unless the trial must

satisfaction of the BUYER, the Classification Society and any other relevant
authority. After the remedial works are completed the SELLER shall arrange to
re-run the gas trial to the extent which will be necessary to demonstrate that
the rectified part of the Gas Plant is then in conformity with this contract and
the Specifications and the proper functioning of the Gas Plant as a whole is
secured.

        (f) All direct costs and expenses of remedying the non-conformity and
re-running the gas trial (including provision of suitable product, utilities and

an unsuccessful gas trial, remedial works and retrials for which the SELLER is
responsible, with the consequence that the classification certificate has not
been issued, will exceed more than twenty (20) days as from the commencement of
the Gas Trials, the SELLER shall, notwithstanding the provisions contained in
Article IX Section 2 and Section 4, pay to the BUYER as liquidated damages
United States Dollars Ten Thousand (US$10,000) for each day of such excess delay

1.      CAUSE OF DELAY

        If, at any time before actual Delivery, either the construction of the
VESSEL, or any performance required hereunder as a prerequisite of delivery of
the VESSEL, is delayed due to war, blockade, revolution, insurrection,
mobilization, civil commotions, riots, strikes, sabotage, lockouts, local
temperature higher than 35 degree centigrade, Acts of God or the public enemy,
plague or other epidemics, quarantines, prolonged failure or restriction of
electric current from an outside source, freight embargoes, if

any, earthquakes, tidal waves, typhoons, hurricanes, storms or other causes
beyond the control of the BUILDER or of its sub-contractors, as the case may be,
or by force majeure of any description, whether of the nature indicated by the
forgoing or not, or by destruction of the BUILDER or works of the BUILDER or its
sub-contractors, or of the VESSEL or any part thereof, by fire, flood, or other
causes beyond the control of the SELLER or its sub-contractors as the case may
be, then, in the event of delay due to the happening of any of the
aforementioned contingencies, the SELLER shall not be liable for such delay and
the time for delivery of the VESSEL under this Contract shall be extended
without any reduction in the Contract Price subject nevertheless to (i) the
provisions of Section 1(a) of Article III as to reduction in Contract Price,
(ii) the BUYER's right of termination under Section 1(a) of Article III and
(iii) all relevant provisions of this Contract which authorize and permit
extension of the time of delivery of the VESSEL.

2.      NOTICE OF DELAY

        Within fourteen (14) days from the date of commencement of any delay on
account of which the SELLER claims that it is entitled under this Contract to an
extension of the time for delivery of the VESSEL, the SELLER shall advise the
BUYER in writing by telex or telefax of the date such delay commenced, and
reasons therefor.

        Likewise within fourteen (14) days after such delay ends, the SELLER
shall advise the BUYER in writing by telex or telefax of the date such delay
ended, and also shall specify the maximum period of the time by which the date
for delivery of the VESSEL is extended by reason of such delay. Failure of the
BUYER to acknowledge the SELLER's notification of any claim for extension of the
Delivery Date within fourteen (14 ) days after receipt by the BUYER of such
notification, shall be deemed to be a waiver by the BUYER of its right to object
to such extension.

                               WARRANTY OF QUALITY

1.      GUARANTEE OF MATERIAL AND WORKMANSHIP

        The SELLER, for a period of twelve (12) months following delivery to the
BUYER of the VESSEL, guarantees the VESSEL, her hull and machinery and all parts
and equipment thereof that are manufactured or furnished or supplied by the
SELLER and/or its sub-contractors under this Contract including material,
equipment (however excluding any parts for the VESSEL which have been supplied
by or on behalf of the BUYER) against all defects which are due to defective
materials, and/or poor workmanship or failure to construct in conformity with
the Specifications.

                                                     Shipbuilding Contract H2245

2.      NOTICE OF DEFECTS

        The BUYER shall notify the SELLER in writing by telex or telefax, as
promptly as possible, after discovery of any defect or deviations for which a
claim is made under this guarantee. The BUYER's written notice shall describe
the nature of the defect and the extent of the damage caused thereby. The SELLER
shall have no obligation under this guarantee for any defects discovered prior
to the expiry date of the guarantee, unless notice of such defects is received
by the SELLER not later than thirty (30) days after such expiry date. Telexed or
telefaxed advice with brief details explaining the nature of such defect and
extent of damage within thirty (30) days after such expiry date and that a claim
is forthcoming will be sufficient to comply with the requirements as to time.

3.      REMEDY OF DEFECTS

        The SELLER shall remedy at its expense any defect, against which the
VESSEL or any part of the equipment thereof is guaranteed under this Article by
making all necessary repairs and/or replacement. Such repairs and/or replacement
will be made by the SELLER.

        However, if it is impractical to make the repair by the SELLER, and if
forwarding by the SELLER of replacement part, and materials cannot be
accomplished without impairing or delaying the operation of the VESSEL, then, in
any such event, the BUYER shall cause the necessary repairs or replacements to
be made elsewhere at the discretion of the BUYER provided that the BUYER shall,
as soon as possible, give the SELLER notice in writing by telex or telefax of
the time and place such repairs will be made, provided always that the burden of
proof as to the necessity for such repairs and replacements shall rest with the
BUYER, and a written confirmation for such repairs or replacement shall be
obtained from the SELLER. Defects that affect the safety of the VESSEL or her
crew and/or constitute an emergency shall be repaired either by the crew or a
BUYER selected contractor in a manner reasonable under the circumstances without
the SELLER's prior approval and the SELLER shall be notified as to the nature
and extent of repairs as soon as possible after the repairs are undertaken and
such repair work will be subject to the mutual agreement between the parties. If
the VESSEL is not thereby delayed or her operation is not thereby delayed or
impaired, the SELLER shall have the right to verify the nature and extent of the
defects complained of by its own representative(s) or that of Classification
Society. The SELLER shall, in such cases, promptly advise the BUYER, by telex or
telefax, after such examination has been completed, of its acceptance or
rejection of the defects as ones justifying the

                                      -31-

remedy under this Article. In all minor cases, the Guarantee Engineer, as
hereinafter provided for, will act for and on behalf of the SELLER.

        In any circumstances, the SELLER shall immediately pay to the BUYER in
United States Dollars by telegraphic transfer the actual cost for such repairs
or replacements including forwarding charges, or at the average cost for making
similar repairs or replacements including forwarding charges as quoted by a
leading shipyard each in China, Singapore, Korea and Spain, whichever is lower:

                  (a) upon the SELLER's acceptance of the defects as justifying 
        remedy under this Article, or

                  (b) If the SELLER neither accepts nor rejects the defects as
        above provided, nor requests arbitration within thirty (30) days after
        its receipt of the BUYER's notice of defects.

        Any dispute shall be referred to arbitration in accordance with the
provisions of Article XIII hereof.

4.      EXTENT OF THE SELLER'S LIABILITY

        The SELLER shall have no obligation and/or liabilities with respect to
defects discovered after the expiration of the period of guarantee specified
above.

        The SELLER shall be liable to the BUYER for defects and damages caused
by any of the defects specified in Section 1 of this Article provided that such
liability of the SELLER shall be limited to damage occasioned within the
guarantee period specified in Paragraph 1 above. The SELLER shall not be
obligated to repair, or to be liable for, damages to the VESSEL, or to any part
of the equipment thereof, due to ordinary wear and tear or caused by defects
other than those specified in Paragraph 1 above, nor shall there be any SELLER's
liability hereunder for defects in the VESSEL, or any part of the equipment
thereof, caused by fire or accidents at sea or elsewhere, or mismanagement,
accidents, negligence, or willful neglect, on the part of the BUYER, its
employees or agents including the VESSEL's officers, crew and passengers, or any
persons on or doing work on the VESSEL other than the SELLER, its employees,
agents or sub-contractors. Likewise, the SELLER shall not be liable for defects
in the VESSEL, or the equipment or any part thereof, due to repairs or
replacement which were made by those other than the SELLER and/or their
sub-contractors, employees or agents.

special loss, or expenses arising from any cause whatsoever including, without

liabilities of the SELLER hereunder are exclusive and in lieu of and the BUYER

or implied, arising by Law or otherwise (including without limitation any
obligations of the SELLER with respect to fitness, merchantability and
consequential damages) or whether or not occasioned by the SELLER's negligence.
This guarantee shall not be extended, altered or varied except by a written
instrument signed by the duly authorized representatives of the SELLER, and the
BUYER.

Engineer") to serve the VESSEL as the BUILDER's representative for a period of
six (6) months from the delivery of the VESSEL. The BUYER and its employees
shall give such Guarantee Engineer full co-operation in carrying out his duties
as the representative of the BUILDER on board the VESSEL. The BUYER shall accord
the Guarantee Engineer(s) the treatment comparable to the VESSEL's Chief
Engineer, and shall provide him/them with accommodation and subsistence at no
cost to the BUILDER and/or the Guarantee Engineer.

        The BUYER shall pay to the Guarantee Engineer the sum of United States
Dollars Three Thousand Five Hundred only (US$3,500 ) per month/per person to
cover his wages and miscellaneous expenses. The BUYER shall also pay the expense
of his repatriation to Shanghai, the People's Republic of China by air upon

liable to and indemnify the BUILDER and/or the Guarantee Engineer for personal

5.      SALE OF THE VESSEL

        (a) In the event of cancellation or rescission of this Contract as above
provided, the SELLER shall have full right and power either to complete or not
to complete the VESSEL as it deems fit and to sell the VESSEL at the best price

terms and conditions as the SELLER may determine.

        In the case of sale of the VESSEL, the SELLER shall give telex or
telefax or written notice to the BUYER.

        (b) In the event of the sale of the VESSEL in its completed state, the
proceeds of sale received by the SELLER shall be applied firstly to payment of

result of the BUYER's default, and then to payment of all unpaid installments
and/or unpaid balance of the Contract Price and interest on such installment at

proceeds of sale received by the SELLER shall be applied firstly to all expenses
attending such sale and otherwise incurred by the SELLER as a result of the
BUYER's default, and then to payment of all costs of construction of the VESSEL

limited to all costs of labor and/or prices paid or to be paid by the SELLER for
the equipment and/or technical design and/or materials purchased or to be
purchased, installed and/or to be installed on the VESSEL) and/or any fees,

less the installments so retained by the SELLER, and compensation to the SELLER
for a reasonable sum of loss of profit due to the cancellation or rescission of

exceeds the total of the amounts to which such proceeds are to be applied as
aforesaid, the SELLER shall promptly pay the excess to the BUYER, provided,
however that the amount of such payment to the BUYER shall in no event exceed
the total amount of installments already paid by the BUYER and the cost of the
BUYER's supplies, if any, without interest.

1.      EXTENT OF INSURANCE COVERAGE

        From the time of keel-laying of the first section or block of the VESSEL
until the same is completed, delivered to and accepted by the BUYER, the SELLER
shall, at its own cost and expense, keep the VESSEL and all machinery,
materials, equipment, appurtenances and outfit, delivered to the BUILDER for the
VESSEL or built into, or installed in or upon the VESSEL, including the BUYER's
Supplies, fully insured with first class Chinese insurance companies for
BUILDER's risk.

        The amount of such insurance coverage shall, up to the date of delivery
of the VESSEL, be in an amount at least equal to, but not limited to, the
aggregate of the payments made by the BUYER to the SELLER including the value of
the BUYER's Supplies. The policy referred to hereinabove shall be taken out in
the name of the SELLER and all losses under such policy shall be payable to the
SELLER.

2.      APPLICATION OF RECOVERED AMOUNT

        (a)       Partial Loss:

                  In the event the VESSEL shall be damaged by any insured cause
        whatsoever prior to acceptance and delivery thereof by the BUYER and in
        the further event that such damage shall not constitute an actual or a
        constructive total loss of the VESSEL, the SELLER shall apply the amount
        recovered under the insurance policy referred to in Section 1 of this
        Article to the repair of such damage satisfactory to the Classification
        Society and other institutions or authorities as described in the
        Specifications without additional expenses to the BUYER.

        (b)       Total Loss:

                                                     Shipbuilding Contract H2245

                          (i) By the mutual agreement between the parties
                  hereto, proceed in accordance with terms of this Contract, in
                  which case the amount recovered under said insurance policy
                  shall be applied to the reconstruction and/or repair of the
                  VESSEL's damages and/or reinstallation of BUYER's supplies
                  without additional expenses to the BUYER, provided the parties
                  hereto shall have first agreed in writing as to such
                  reasonable extension of the Delivery Date and adjustment of
                  other terms of this Contract including the Contract Price as
                  may be necessary for the completion of such reconstruction; or

                          (ii) If due to whatever reasons the parties fail to
                  agree on the above, then the BUYER shall deliver a written
                  notice of rejection to SELLER and the SELLER shall refund
                  immediately to the BUYER the amount described in Article II,
                  Section 7, whereupon this Contract shall be deemed to be
                  canceled and all rights, duties, liabilities and obligations
                  of each of the parties to the other shall terminate forthwith.

                          (iii) Notwithstanding the provisions of (i) and (ii)
                  above, Seller may elect to postpone delivery of the Vessel
                  subject to the provisions of Article III, Section (1)(a).

                  Within thirty (30) days after receiving telex or telefax
        notice of any damage to the VESSEL constituting an actual or a
        constructive total loss, the BUYER shall notify the SELLER in writing or
        by telex of its agreement or disagreement under this sub-paragraph. In
        the event the BUYER fails to so notify the SELLER, then such failure
        shall be construed as a disagreement on the part of the BUYER. This
        Contract shall be deemed as rescinded and canceled and the BUYER shall
        receive the refund as hereinabove provided and the provisions hereof
        shall apply.

3.      TERMINATION OF THE SELLER'S OBLIGATION TO INSURE

        The SELLER's obligation to insure the VESSEL hereunder shall cease and
terminate forthwith upon Delivery thereof to and acceptance by the BUYER.

                                  ARTICLE XIII

                                                     Shipbuilding Contract H2245

        Should any dispute of any nature arise in respect of this Contract, its
performance or interpretation which is not decided in accordance with Article
XIII, Section 2 below, such dispute shall be settled by arbitration in London,
England in accordance with the rules of the London Maritime Arbitrators
Association Inc. and otherwise in accordance with the provisions of the Laws of
England. The party who desires arbitration of any such dispute shall give
written notice to the other party. The notice shall state the name and address
of the arbitrator whom it appoints and describe the specific nature of the
particular dispute. Such notice shall be sent by registered air mail and shall
be addressed in the manner set forth in Article XIX, and the other party shall,
within thirty (30) days following the receipt of said notice, give written
notice to the party requesting the arbitration as to the name and address of the
arbitrator whom it appoints, which notice shall be sent by registered air mail
and shall be addressed in the manner set forth in Article XIX, provided that if
the other party should fail to so appoint its arbitrator, the arbitrator
appointed by the party desiring the arbitration may proceed with the arbitration
hearing and issue an award. Otherwise the two arbitrators so chosen shall select
a third arbitrator. The applicable law of England on all matters at issue shall
apply. A judgement based upon the decision of the majority of the arbitrators or
the sole arbitrator, as the case may be, may be entered in the appropriate court
of any country having jurisdiction of either party. The arbitrators shall also
decide which party, or the extent to which each party, shall pay costs of
arbitration. Unless and to the extent otherwise determined by the arbitrator(s),
reference to arbitration shall not relieve the BUILDER of its obligation
diligently to proceed with the construction, completion and delivery of the
VESSEL, but the majority of the arbitrators or the sole arbitrator, as the case
may be, shall decide the extent to which the Delivery Date shall be extended by
virtue of the dispute having been referred to arbitration.

2.      ALTERNATIVE ARBITRATION BY AGREEMENT

        Notwithstanding the preceding provisions of this Article, it is
recognized that in the event of any dispute or difference of opinion arising in
regard to the construction of the VESSEL, her machinery and equipment, or
concerning the quality of materials or workmanship thereof or thereon, such
dispute may be referred to the Classification Society upon mutual agreement of
the parties hereto. In such case, the opinion of the Classification Society
shall be final and binding on the parties hereto.

3.      NOTICE OF AWARD

        Notice of any award shall immediately be given in writing or by telex
confirmed in writing to the SELLER and the BUYER.

party shall have all the rights and assume all the obligations of the BUYER
hereunder with respect to said VESSEL and the responsibility of the BUYER

this Contract. The BUYER shall deliver to the SELLER a Notice of Assignment and
Acknowledgement as to any assignment of this Contract to the Trustee Bank.

Navigator Holdings PLC
c/o Cambridge Petroleum Transport Corporation
535 Madison Avenue
19th Floor
New York, New York 10022


Dear Sirs:

At the request of China Shipbuilding Trading Company, Limited ("CSTC") and
Jiangnan Shipyard (the "Builder" and, together with CSTC, the "SELLER") and in
consideration of Navigator Holdings PLC (the "BUYER") agreeing to pay SELLER the
installments of the contract price (the "Contract Price") pursuant to the
Amended and Restated Shipbuilding Contract dated the 26th day of June, 1997, as
amended, supplemented or otherwise modified from time to time (hereinafter
called the "Contract") made by and between the BUYER and the SELLER for the
construction of one (1) 22,000 cubic meter liquefied ethylene gas carrier having
Hull No. 2245 (hereinafter called the "VESSEL"), The Export Import Bank of China
the "Bank") the undersigned, do guarantee the payment (and not merely the
collectability of the same) to the BUYER by the SELLER immediately upon demand
of an amount up to but not exceeding a total amount as set forth in Schedule 1
hereto (calculated in accordance with the immediately following paragraph),
together with simple interest thereon calculated at the rate of ten percent
(10.0%) per annum on the basis of a 360 day year from and including the date of
receipt of demand to but not including the date of remittance by telegraphic
transfer of such refund.

Subject to BUYER making installment payments in accordance with Article II of
the Contract, the amount of this Guarantee will be automatically increased
during the term of this Guarantee and shall be equal to the sum of: (i) the
amount set forth on Schedule 1 hereto calculated as of the first day of the
calendar month in which the Date

                                       A-1




                                                       Amended and Restated
                                                     Shipbuilding Contract H2245

of Rejection occurs; and (ii) an amount equal to the product of (X) the
difference between (1) the amount set forth on Schedule 1 hereto calculated as
of the first day of the calendar month immediately succeeding the month in which
the Date of Rejection occurs and (2) the amount set forth on Schedule 1 hereto
as of the first day of the month in which the Date of Rejection of the vessel
under the Contract occurs and (y) a fraction the numerator of which is numeric
day of the month of the date on which the Refund Amount (as hereinafter defined)
is actually paid and the denominator of which is 30 (collectively, the "Refund
Amount").

BUYER's right to demand payment under this Guarantee shall become effective on
the earlier to occur of (i) April 1, 2001, (ii) the date on which the SELLER
fails to pay any liquidated damages payable to BUYER as provided in Section 1(a)
of Article III of the Contract, (iii) upon the cancellation, termination or
rescission of the Contract by the BUYER in accordance with the terms of Contract
as set forth in Article III, 1(a), 2(c), 3(c), 4(c), 5(c), Article X, Article
XII 2(b), or Article XVI (b) or (c), or (iv) the insolvency or bankruptcy of
BUILDER.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to us by the BUYER.

Payment under this Guarantee is available at the counters of ______________ Bank
against presentation of the BUYER's signed statement issued in the form attached
hereto as Appendix A ("Notice of Demand"). If the Notice of Demand is received
by the Bank by 12:00 noon local time on a banking day, the Bank shall pay the
Refund Amount (plus interest thereon) in immediately available funds within ten
(10) banking days. If the Notice of Demand is received by the Bank after 12:00
noon local time on a banking day, the Bank shall pay the Refund Amount (plus
interest thereon) in immediately available funds within eleven (11) banking
days.

This Guarantee is available for one payment only, whether for the full amount
hereof or any part thereof, as may be demanded by the BUYER. In the event that
the BUYER's demand is for a lesser amount than the amount of this Guarantee, the
interest payable will be calculated on the amount of the BUYER's demand and not
on the amount of this Guarantee.

We agree that this Guarantee shall be a continuing guarantee and (i) shall not
be impaired or discharged by the granting of time or any other indulgence to the
SELLER, or any other forbearance (whether as to payment, time, performance, or
otherwise) which might, but for this provision, have any such effect; (ii) shall
not be conditioned or contingent upon the BUYER's pursuit of any remedy that it
has against the SELLER;

                                       A-2




                                                       Amended and Restated
                                                     Shipbuilding Contract H2245

and (iii) shall be unconditional irrespective of any other circumstance that
might otherwise constitute a legal or equitable discharge of a surety or
guarantor under applicable law, and we hereby waive any and all rights (whether
by counterclaim, set off or otherwise) and defenses at law or in equity that may
be available to us by reason of such circumstance.

This Guarantee shall become effective from the time of the actual receipt of the
first installment by the SELLER from the BUYER under the Contract and the Refund
Amount payable under this Guarantee shall correspond to the total installment
payments actually made by the BUYER to the SELLER from time to time under the
Contract prior to the delivery of the VESSEL including applicable interest.

This Guarantee shall expire and become null and void on the earlier to occur of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
the Bank of either a copy of the Protocol of Delivery and Acceptance of the
VESSEL, purportedly signed by the BUYER and the SELLER and issued in the form
attached hereto as Appendix B or a copy of the Certificate of Completion of the
Vessel signed by the respective parties thereto in the form attached hereto as
Appendix C; or (iii) 5:00 p.m. New York time on May 1, 2001, in any such case
this Guarantee shall be returned to us; provided, the Bank further agrees that
its obligations hereunder shall continue to be effective or reinstated, as the
case may be, if at any time any payment, or any part thereof, made by the SELLER
is rescinded or must otherwise be restored by the BUYER upon the bankruptcy or
reorganization of the SELLER.

Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER confirmed by an arbitrator stating that the BUYER's
claim to cancel the Contract or the BUYER's claim for refundment thereunder has
been disputed and referred to arbitration in accordance with the provisions of
the Contract, the period of validity of this Guarantee shall be extended until
thirty (30) days after the final award shall be rendered in the arbitration and
a copy thereof acknowledged by the arbitrators. In such case, this Guarantee
shall not be available unless and until such acknowledged copy of the final
award in the Arbitration justifying the BUYER's claim is presented to us;
subject to any appeal of such final award which may be permitted under English
law; provided the Refund Amount shall be adjusted to reflect the delay resulting
from such arbitration and shall be calculated in accordance with Schedule 1
hereto to the date payment is actually made.




                                       A-3

Dear Sirs:

At the request of China Shipbuilding Trading Company, Limited ("CSTC") and
Jiangnan Shipyard (the "Builder" and together with CSTC collectively called the
"SELLER") and in consideration of Navigator Holdings, PLC (the "BUYER") agreeing
to pay SELLER the installments of the contract price (the "Contract Price")
pursuant to the Amended and Restated Shipbuilding Contracts dated the 26th day
of June, 1997, as amended, supplemented or otherwise modified from time to time
(hereinafter called the "Contracts") made by and between the BUYER and the
SELLER for the construction of five (5) 22,000 cubic meter liquefied ethylene
gas carriers respectively having Hull Nos. 2245, 2246, 2247, 2248 and 2249
(hereinafter called the "VESSELS"), Export-Import Bank of China (the "Bank")
guarantees the payment (and not merely the collectability of the same) to the
BUYER by the SELLER, immediately upon demand, of an amount up to but not
exceeding a total aggregate amount of United States Dollars Twenty Six Million
Seven Hundred Thousand (US$26,700,000) (the "Payment Amount"), if and when the
same or any part thereof becomes payable to BUYER from the SELLER under any
Contract or Contracts if any such Contract or Contracts are cancelled by the
BUYER in accordance with the terms (Article III, 1(a), 2(c), 3(c), 4(c), 5(c),
Article X, Article XII 2(b) and Article XVI (b) and (c)) of such Contract or
Contracts (any a "Cancellation Event"). This Performance Bond shall become
effective upon actual receipt in full by the SELLER of the initial installment
due under each of the Contracts.

Payment shall be made to the BUYER in United States Dollars in accordance with
the payment instruction given to the BANK by the BUYER.


                                       B-1




                                                       Amended and Restated
                                                     Shipbuilding Contract H2245

Payment under this Performance Bond is available at the counters of
Export-Import Bank of China in __________________ against presentation of the
BUYER's signed statement issued in the form attached hereto as Appendix A
("Notice of Demand"). The Notice of Demand shall set forth the dollar amount to
be paid to the BUYER under this Performance Bond, which amount shall be based
upon Schedule 1 attached hereto (the "Demand Amount") provided such Demand
Amount shall not exceed the Payment Amount. As to any date on which a Notice of
Demand is presented, the Demand Amount shall be equal to the amount set forth
opposite the calendar month in which such Notice of Demand is presented under
the column heading specified in the Notice of Demand. If the Notice of Demand is
received by the Bank by 12:00 noon local time on a banking day, the Bank shall
pay the Demand Amount in immediately available funds within ten (10) banking
days. If the Notice of Demand is received by the Bank after 12:00 noon local

occur of (i) April 1, 2001, (ii) the date on which the SELLER fails to pay any
liquidated damages payable to BUYER as provided in Section 1(a) of Article III
of the Contracts, (iii) the occurrence of a Cancellation Event or (iv) the
bankruptcy or insolvency of the Builder.

This Performance Bond is available for one payment only, whether for the full
amount hereof or any part thereof, as may be demanded by the BUYER.

We agree that this Performance Bond shall be a continuing guarantee and (i)
shall not be impaired or discharged by the granting of time or any other
indulgence to the SELLER, or any other forbearance (whether as to payment, time,
performance, or otherwise) which might, but for this provision, have any such
effect; (ii) shall not be conditioned or contingent upon the BUYER's pursuit of
any remedy that it has against the SELLER; and (iii) shall be unconditional
irrespective of any other circumstance that might otherwise constitute a legal
or equitable discharge of a surety or guarantor under applicable law, and we
hereby waive any and all rights (whether by counterclaim, set off or otherwise)
and defenses at law or in equity that may be available to us by reason of such
circumstance.

This Performance Bond shall expire and become null and void on the earlier of
(i) the receipt by the BUYER of the sum guaranteed hereby; (ii) the receipt by
Bank of a copy of the Protocol of Acceptance and Delivery or Certificates of
Completion for each of the five (5) VESSELS in the form of Appendix B or
Appendix C to this Performance Bond; or (iii) 5:00 p.m. New York time on May 1,
2001, in any such case this Performance Bond shall be returned to us; provided,
the Bank further agrees that its obligations hereunder shall continue to be
effective or reinstated, as the case may be, if at any time any payment, or any
part thereof, made by the SELLER is rescinded or must otherwise be restored by
the BUYER upon the bankruptcy or reorganization of the SELLER.

                                                     Shipbuilding Contract H2245

Notwithstanding the provisions hereinabove, in case we receive notification from
the BUYER or the SELLER stating that the BUYER's claim to cancel the Contracts
or the BUYER's claim for payment thereunder has been disputed and referred to
arbitration in accordance with the provisions of the Contracts, the period of
validity of this Performance Bond shall be extended until thirty (30) days after
the final award shall be rendered in the arbitration and a copy thereof
acknowledged by the arbitrators. In such case, this Performance Bond shall not
be available unless and until such acknowledged copy of the final award in the
Arbitration justifying the BUYER's claim is presented to us; subject to any
appeal of such final award which may be permitted under English law.

the BUYER or the SELLER confirmed by an arbitrator stating that the BUYER's
claim to cancel the Contracts or the BUYER's claim for refundment thereunder has
been disputed and referred to arbitration in accordance with the provisions of
the Contract, the period of validity of this Performance Bond shall be extended
until thirty (30) days after the final award shall be rendered in the
