                                   ARTICLE 1

                   Definitions and Incorporation by Reference
                   ------------------------------------------

            SECTION     1.01. Definitions.

            "Acquisition Contract" means a sale and purchase contract executed
by the Company or a Restricted Subsidiary to acquire an additional Vessel or
Vessels or any Shipping Business Assets.

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

            "Adjusted Treasury Rate" means, with respect to any redemption date,
(i) the yield, under the heading which represents the average for the
immediately preceding week, appearing in the most recently published statistical
release designated "H.15(519)" or any successor publication which is published
weekly by the Board of Governors of the Federal Reserve System and which
establishes yields on actively traded United States Treasury securities adjusted
to constant maturity under the caption "Treasury Constant Maturities," for the
maturity corresponding to the Comparable Treasury Issue (if no maturity is
within three months before or after November 24, 2009, yields for the two
published maturities most closely corresponding to the Comparable Treasury Issue
shall be determined and the Adjusted Treasury Rate shall be interpolated or
extrapolated from such yields on a straight line basis, rounding to the nearest
month) or (ii) if such release (or any successor release) is not published
during the week preceding the calculation date or does not contain such yields,
the rate per year equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the Comparable Treasury Price for such redemption date, in each case

plus 0.50%.

            "Affiliate" of any specified Person means any other Person, directly

control with such specified Person. For the purposes of this definition,
"control" when used with respect to any Person means the power to direct the

<PAGE>

purposes of Sections 4.04, 4.06 and 4.08 only, "Affiliate" shall also mean any
beneficial owner of Capital Stock representing 5% or more of the total voting
power of the Voting Stock (on a fully diluted basis) of the Company or of rights
or warrants to purchase such Capital Stock (whether or not currently
exercisable) and any Person who would be an Affiliate of any such beneficial

            "Applicable Premium" means with respect to a Security at any

(1) the redemption price of such Security on November 24, 2009 (such redemption
price being described in Section 5 of the Securities exclusive of any accrued
interest), plus (2) all required remaining scheduled interest payments due on
such Security through November 24, 2009 (but excluding accrued and unpaid
interest to the redemption date), computed using a discount rate equal to the
Adjusted Treasury Rate, over (B) the principal amount of such Security on such
redemption date.

the Mortgaged Vessels has been determined.

            "Appraised Value" means the average of the fair market sale values
as of a specified date of a specified asset that would be obtained in an
arm's-length transaction between an informed and willing seller under no
compulsion to sell and an informed and willing buyer under no compulsion to buy,
as determined by two Appraisers selected by the Company and, in the event either
of such Appraisers is not a Designated Appraiser (as defined in the definition
of Appraiser), reasonably acceptable to the Trustee. If the Trustee does not
accept an Appraiser (other than a Designated Appraiser) selected by the Company
within 10 days of the first giving of notice by the Company to the Trustee
requesting a determination of an Appraised Value (the "Appraisal Request Date"),
such Appraised Value shall be determined by a panel of three Appraisers, one of
whom shall be selected by the Company, another of whom shall be selected by the
Trustee and the third of whom shall be selected by such other two Appraisers or,
if such Appraisers shall be unable to agree upon a third Appraiser within 5 days
of the selection date of the second of such two Appraisers, by an arbitrator
mutually acceptable to the Company and the Trustee; provided, however, that, if
either party shall not select its Appraiser within 20 days after the Appraisal
Request Date, such Appraised Value shall be determined solely by the Appraiser
selected by the other party. The Appraiser or Appraisers appointed pursuant to
the foregoing procedure shall be instructed to determine such Appraised Value
within 25 days after the final appointment of any Appraiser pursuant hereto, and
such determination shall be final and binding upon the parties. If three
Appraisers shall be appointed, (a) if the median of the determinations of the
Appraisers shall equal the average of such determinations, such average shall
constitute the determination of the Appraisers; otherwise (b) the determination
of the Appraiser that shall differ most from the other two Appraisers shall be
excluded, the remaining two determinations shall be averaged and such average
shall constitute the determination of the Appraisers. For this purpose, the
purchase price of any Mortgaged Vessel acquired after the most recent Appraisal
Date shall constitute that Vessel's Appraised Value.

<PAGE>

to (ii) Consolidated Interest Expense for such four fiscal quarters; provided,
however, that:

            (1) if the Company or any Restricted Subsidiary has Incurred any
      Indebtedness since the beginning of such period that remains outstanding
      on the date of determination or if the transaction giving rise to the need
      to calculate the Consolidated Coverage Ratio is an Incurrence of
      Indebtedness, or both, EBITDA and Consolidated Interest Expense for such
      period shall be calculated after giving effect on a pro forma basis to
      such Indebtedness as if such Indebtedness had been Incurred on the first
      day of such period and the discharge of any other Indebtedness repaid,
      repurchased, defeased or otherwise discharged with the proceeds of such

      repurchased, defeased or otherwise discharged any Indebtedness since the
      beginning of such period or if any Indebtedness is to be repaid,
      repurchased, defeased or otherwise discharged (in each case other than
      Indebtedness Incurred under any revolving credit facility unless such
      Indebtedness has been permanently repaid and has not been replaced) on the
      date of the transaction giving rise to the need to calculate the
      Consolidated Coverage Ratio, EBITDA and Consolidated Interest Expense for
      such period shall be calculated on a pro forma basis as if such discharge
      had occurred on the first day of such period and as if the Company or such
      Restricted Subsidiary had not earned the interest income actually earned
      during such period in respect of cash or Temporary Cash Investments used
      to repay, repurchase, defease or otherwise discharge such Indebtedness;

            (3) if since the beginning of such period the Company or any
      Restricted Subsidiary shall have made any Asset Sale, the EBITDA for such
      period shall be reduced by an amount equal to the EBITDA (if positive)
      directly attributable to the assets which are the subject of such Asset
      Sale for such period, or increased by an amount equal to the EBITDA (if
      negative), directly attributable thereto for such period and Consolidated
      Interest Expense for such period shall be reduced by an amount equal to
      the Consolidated Interest Expense directly attributable to any
      Indebtedness of the Company or any Restricted Subsidiary repaid,
      repurchased, defeased or otherwise discharged with respect to the Company
      and its continuing Restricted Subsidiaries in connection with such Asset
      Sale for such period (or, if the Capital Stock of any Restricted
      Subsidiary is sold, the Consolidated Interest Expense for such period
      directly attributable to the Indebtedness of such Restricted Subsidiary to
      the extent the Company and its continuing Restricted Subsidiaries are no
      longer liable for such Indebtedness after such sale);

            (4) if since the beginning of such period the Company or any
      Restricted Subsidiary (by merger or otherwise) shall have made an
      Investment in any Restricted Subsidiary (or any person which becomes a
      Restricted Subsidiary) or an acquisition of assets, including any
      acquisition of assets occurring in connection with a transaction requiring
      a calculation to be made hereunder, which constitutes all or substantially
      all of an operating unit of a business, EBITDA and Consolidated Interest
      Expense for such period shall be calculated after giving pro forma effect
      thereto (including the Incurrence of any Indebtedness) as if such
      Investment or acquisition occurred on the first day of such period; and

            (5) if since the beginning of such period any Person (that
      subsequently became a Restricted Subsidiary or was merged with or into the
      Company or any Restricted Subsidiary since the beginning of such period)
      shall have made any Asset Sale, any Investment or acquisition of assets
      that would have required an adjustment pursuant to clause (3) or (4) above
      if made by the Company or a Restricted Subsidiary during such period,

                                    Page 11

<PAGE>

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

For purposes of this definition, whenever pro forma effect is to be given to an
acquisition of a Vessel or the financing thereof, the Company may (i) if the
Vessel is to be subject to a time charter of at least one year's duration by the
Company, apply pro forma EBITDA for such Vessel based on such new time charter
or (ii) if the Vessel is to be subject to hire on a voyage charter basis by the
Company, apply EBITDA for such Vessel based upon historical earnings of the most
comparable Vessel of the Company or any of its Subsidiaries (as determined in
good faith by the Board of Directors) during such period, or if there is no such
comparable Vessel, based upon industry average earnings for comparable vessels
(as determined in good faith by the Board of Directors).

Restricted Subsidiaries which may properly be classified as current liabilities
(including taxes accrued as estimated), on a consolidated basis, after
eliminating (i) all intercompany items between the Company and any Restricted
Subsidiary and (ii) all current maturities of long-term Indebtedness, all as
determined in accordance with GAAP consistently applied.

interest expense attributable to leases constituting part of a Sale/Leaseback
Transaction, (ii) amortization of debt discount and debt issuance cost, (iii)

Subsidiary to the extent paid in cash in such period, (viii) interest incurred
in connection with Investments in discontinued operations, (ix) interest
accruing on any Indebtedness of any other Person to the extent such Indebtedness
is Guaranteed by (or secured by the assets of) the Company or any Restricted
Subsidiary and (x) the cash contributions to any employee stock ownership plan
or similar trust to the extent such contributions are used by such plan or trust
to pay interest or fees to any Person (other than the Company) in connection
with Indebtedness Incurred by such plan or trust.

            "Consolidated Net Income" means, for any period, the net income of
the Company and its consolidated Subsidiaries; provided, however, that there
shall not be included in such Consolidated Net Income:

            (i) any net income of any Person (other than the Company) if such
      Person is not a Restricted Subsidiary, except that (A) subject to the
      exclusion contained in clause (iv) below, the Company's equity in the net

                                    Page 12

      income of any such Person for such period shall be included in such
      Consolidated Net Income up to the aggregate amount of cash actually
      distributed by such Person during such period to the Company or a
      Restricted Subsidiary as a dividend or other distribution (subject, in the
      case of a dividend or other distribution paid to a Restricted Subsidiary,
      to the limitations contained in clause (iii) below) and (B) the Company's
      equity in a net loss of any such Person for such period shall be included
      in determining such Consolidated Net Income;

            (ii) any net income (or loss) of any Person acquired by the Company
      or a Subsidiary in a pooling of interests transaction for any period prior
      to the date of such acquisition;

            (iii) any net income of any Restricted Subsidiary if such Restricted
      Subsidiary is subject to restrictions, directly or indirectly, on the
      payment of dividends or the making of distributions by such Restricted
      Subsidiary, directly or indirectly, to the Company, except that (A)
      subject to the exclusion contained in clause (iv) below, the Company's
      equity in the net income of any such Restricted Subsidiary for such period
      shall be included in such Consolidated Net Income, but only to the extent
      that such Restricted Subsidiary was not prohibited from distributing such
      net income of such Restricted Subsidiary during such period as a dividend
      or other distribution (subject, in the case of a dividend or other
      distribution paid to another Restricted Subsidiary, to the limitation
      contained in this clause) and (B) the Company's equity in a net loss of
      any such Restricted Subsidiary for such period shall be included in
      determining such Consolidated Net Income;

            (iv) any gain (but not loss) realized upon the sale or other
      disposition of any assets of the Company or its consolidated Subsidiaries
      (including pursuant to sales of Vessels and to any sale-and-leaseback
      arrangement) and any gain (but not loss) realized upon the sale or other
      disposition of any Capital Stock of any Person, in each case which is not
      sold or otherwise disposed of in the ordinary course of business, as
      determined in good faith by the Board of Directors;

            (v) extraordinary gains or losses; and

            (vi) the cumulative effect of a change in accounting principles.

            Notwithstanding the foregoing, for the purposes of Section 4.04
only, there shall be excluded from Consolidated Net Income any dividends,
repayments of loans or advances or other transfers of assets from Unrestricted
Subsidiaries to the Company or a Restricted Subsidiary to the extent such
dividends, repayments or transfers increase the amount of Restricted Payments
permitted pursuant to Section 4.04(a)(3)(D).

            "Consolidated Net Tangible Assets" as of any date of determination,
means the total amount of assets (less accumulated depreciation and
amortization, allowances for doubtful receivables, other applicable reserves and
other properly deductible items) which would appear on a balance sheet of the
Company and its Restricted Subsidiaries, determined on a consolidated basis in

having an individual Vessel Percentage of approximately 0.13%.

; provided, however, that each Vessel Percentage shall be adjusted, in
connection with any redemption of the Securities following a Sale or Loss of a
Mortgaged Vessel, in each case to give effect to the occurrence of, and after
giving effect to, (i) the acquisition of a Vessel with Escrowed Property and the
delivery of a Mortgage with respect to such Vessel, (ii) the delivery after the
Issue Date of any Qualified Substitute Vessel as part of the Collateral pursuant
to the terms of this Indenture, (iii) the delivery after the Issue Date of any

the percentage that the Appraised Value of such Mortgaged Vessel at the time of
and after giving effect to such occurrence bears to the sum of the aggregate
Appraised Value of the remaining Mortgaged Vessels at the time of and after
giving effect to such occurrence plus the amount of Escrowed Property then
remaining as part of the Collateral. Notwithstanding the foregoing, if any
Vessel Percentage is required to be calculated or adjusted at a time when cash
is on deposit with the Trustee as part of the Collateral as a result of the sale
of a Mortgaged Vessel or the occurrence of an Event of Loss with respect to a
Mortgaged Vessel, the amount of such cash on deposit shall be deemed to be the
Appraised Value of such Vessel giving rise to such cash on deposit and such
Vessel shall be deemed to remain a Mortgaged Vessel for purposes of such
computation or adjustment of Vessel Percentage. The Company shall make all
calculations provided for herein and shall, for any such calculations made after
the Issue Date, provide to the Trustee an Officers' Certificate certifying that
such calculations were performed in accordance the provisions hereof.

                                   ARTICLE 2

                                 The Securities
                                 --------------

            SECTION 2.01. Form and Dating. Provisions relating to the Initial
Securities, the Private Exchange Securities and the Exchange Securities are set
forth in the Rule 144A/Regulation S/IAI Appendix attached hereto (the
"Appendix") which is hereby incorporated in and expressly made part of this
Indenture. The Initial Securities and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit 1 to the Appendix
which is hereby incorporated in and expressly made a part of this Indenture. The
Exchange Securities, the Private Exchange Securities and the Trustee's
certificate of authentication shall be substantially in the form of Exhibit A,
which is hereby incorporated in and expressly made a part of this Indenture. The
Securities may have notations, legends or endorsements required by law, stock
exchange rule, agreements to which the Company is subject, if any, or usage
(provided that any such notation, legend or endorsement is in a form acceptable
to the Company). Each Security shall be dated the date of its authentication.
The terms of the Securities set forth in the Appendix and Exhibit A are part of
the terms of this Indenture.

            SECTION 2.02. Execution and Authentication. One Officer shall sign
the Securities for the Company by manual or facsimile signature. The Company's
seal shall be impressed, affixed, imprinted or reproduced on the Securities and
may be in facsimile form.

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

            A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

            The Trustee shall authenticate and deliver Securities for original
issue in aggregate principal amount of $180.0 million upon a written order of
the Company signed by an Officer of the Company. Such order shall specify the
amount of the Securities to be authenticated and the date on which the original
issue of Securities is to be authenticated. The aggregate principal amount of
Securities outstanding at any time may not exceed that amount except as provided
in Section 2.06.

            The Trustee may appoint an authenticating agent reasonably
acceptable to the Company to authenticate the Securities. Unless limited by the
terms of such appointment, an authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as any Registrar, Paying Agent or agent
for service of notices and demands.

            SECTION 2.03. Registrar and Paying Agent. The Company shall maintain
an office or agency where Securities may be presented for registration of
transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent"). The Registrar
shall keep a register of the Securities and of their transfer and exchange. The

                                    Page 33

<PAGE>

Company may have one or more co-registrars and one or more additional paying
agents. The term "Paying Agent" includes any additional paying agent.

            The Company shall enter into an appropriate agency agreement with
any Registrar, Paying Agent or co-registrar not a party to this Indenture, which
shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall notify
the Trustee of the name and address of any such agent. If the Company fails to
maintain a Registrar or Paying Agent or to notify the Trustee as provided in the
previous sentence, the Trustee shall act as such and shall be entitled to
appropriate compensation therefor pursuant to Section 7.07. The Company or any
of its domestically incorporated Wholly Owned Subsidiaries may act as Paying
Agent, Registrar, co-registrar or transfer agent.

            The Company initially appoints the Trustee as Registrar and Paying
Agent in connection with the Securities.

            SECTION 2.04. Paying Agent To Hold Money in Trust. Prior to each due
date of the principal and interest on any Security, the Company shall deposit
with the Paying Agent a sum sufficient to pay such principal and interest when
so becoming due. The Company shall require each Paying Agent (other than the
Trustee) to agree in writing that the Paying Agent shall hold in trust for the
benefit of Securityholders or the Trustee all money held by the Paying Agent for
the payment of principal of or interest on the Securities and shall notify the
Trustee of any default by the Company in making any such payment. If the Company
or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as
Paying Agent and hold it as a separate trust fund. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee and to account
for any funds disbursed by the Paying Agent. Upon complying with this Section,
the Paying Agent shall have no further liability for the money delivered to the
Trustee.

            SECTION 2.05. Securityholder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Securityholders. If the Trustee is not the
Registrar, the Company shall furnish to the Trustee, in writing at least five
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Securityholders.

            SECTION 2.06. Replacement Securities. If a mutilated Security is
surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-401(1) of the Uniform Commercial Code are met and the Holder satisfies
any other reasonable requirements of the Trustee. If required by the Trustee or
the Company, such Holder shall furnish an indemnity bond sufficient in the
judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent, the Registrar and any co-registrar from any loss which any of them
may suffer if a Security is replaced. The Company and the Trustee may charge the
Holder for their expenses in replacing a Security.

            Every replacement Security is an additional Obligation of the
Company.

            SECTION 2.07. Outstanding Securities. Securities outstanding at any
time are all Securities authenticated by the Trustee except for those canceled
by it, those delivered to it for cancelation and those described in this Section
as not outstanding. A Security does not cease to be outstanding because the
Company or an Affiliate of the Company holds the Security.

            If a Security is replaced pursuant to Section 2.06, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to

                                    Page 34

<PAGE>

them that the replaced Security is held by a bona fide purchaser.

            If the Paying Agent segregates and holds in trust, in accordance
with this Indenture, on a redemption date or maturity date money sufficient to
pay all principal and interest payable on that date with respect to the
Securities (or portions thereof) to be redeemed or maturing, as the case may be,
then on and after that date such Securities (or portions thereof) cease to be
outstanding and interest on them ceases to accrue.

            SECTION 2.08. Temporary Securities. Until definitive Securities are
ready for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate definitive Securities and
deliver them in exchange for temporary Securities.

            SECTION 2.09. Cancelation. The Company at any time may deliver
Securities to the Trustee for cancelation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel and
destroy (subject to the record retention requirements of the Exchange Act) all
Securities surrendered for registration of transfer, exchange, payment or
cancelation and deliver a certificate of such destruction to the Company unless
the Company directs the Trustee to deliver canceled Securities to the Company.
The Company may not issue new Securities to replace Securities it has redeemed,
paid or delivered to the Trustee for cancelation.

            SECTION 2.10. Defaulted Interest. If the Company defaults in a
payment of interest on the Securities, the Company shall pay defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful
manner. The Company may pay the defaulted interest to the persons who are
Securityholders on a subsequent special record date. The Company shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail to each
Securityholder a notice that states the special record date, the payment date
and the amount of defaulted interest to be paid.

            SECTION 2.11. CUSIP Numbers. The Company in issuing the Securities
may use "CUSIP" numbers (if then generally in use) and, if so, the Trustee shall
use "CUSIP" numbers in notices of redemption as a convenience to Holders;
provided, however, that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Securities or as
contained in any notice of a redemption and that reliance may be placed only on
the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.

            SECTION 2.12. Transfer and Exchange. The Securities shall be issued
in registered form and shall be transferable only upon the surrender of a
Security for registration of transfer. When a Security is presented to the
Registrar or a co-registrar with a request to register a transfer, the Registrar
shall register the transfer as requested if the requirements of this Indenture
and Section 8-401(1) of the Uniform Commercial Code are met. When Securities are
presented to the Registrar or a co-registrar with a request to exchange them for
an equal principal amount of Securities of other denominations, the Registrar
shall make the exchange as requested if the same requirements are met. To permit
registration of transfers and exchanges, the Company shall execute and the
Trustee shall authenticate Securities at the Registrar's or co-registrar's
request. The Company may require payment of a sum sufficient to pay all taxes,
assessments or other governmental charges in connection with any transfer or
exchange pursuant to this Section (other than any such transfer taxes,
assessments or similar governmental charge payable upon exchange or transfer
pursuant to Sections 3.06, 4.11 and 9.05). The Company shall not be required to

                                    Page 35

<PAGE>

make and the Registrar need not register transfers or exchanges of Securities
selected for redemption (except, in the case of Securities to be redeemed in
part, the portion thereof not to be redeemed) or any Securities for a period of
15 days before a selection of Securities to be redeemed or 15 days before an
interest payment date.

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

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

                                    ARTICLE 3

                                   Redemption

            SECTION 3.01. Notices to Trustee. If the Company elects to redeem
Securities pursuant to paragraph 5 of the Securities or is required to redeem
Securities pursuant to paragraph 6 of the Securities, it shall notify the
Trustee in writing of the redemption date, the principal amount of Securities to
be redeemed and the paragraph of the Securities pursuant to which the redemption
will occur.

            If the Company is required to redeem Securities pursuant to
paragraph 6 of the Securities, it may reduce the principal amount of Securities
required to be redeemed to the extent it is permitted a credit by the terms of
the Securities and it notifies the Trustee of the amount of the credit and the
basis for it. If the reduction is based on a credit for redeemed or canceled
Securities that the Company has not previously delivered to the Trustee for
cancelation, it shall deliver such Securities with the notice.

            The Company shall give each notice to the Trustee provided for in
this Section not less than 45 days nor more than 60 days before the redemption
date unless the Trustee consents in writing to a shorter period. Such notice
shall be accompanied by an Officers' Certificate and an Opinion of Counsel from
the Company to the effect that such redemption will comply with the conditions
herein.

            SECTION 3.02. Selection of Securities To Be Redeemed. If fewer than
all the Securities are to be redeemed, the Trustee shall select the Securities
to be redeemed pro rata to the extent practicable. The Trustee shall make the
selection from outstanding Securities not previously called for redemption. The
Trustee may select for redemption portions of the principal of Securities that
have denominations larger than $1,000. Securities and portions of them the
Trustee selects shall be in amounts of $1,000 or a whole multiple of $1,000.
Provisions of this Indenture that apply to Securities called for redemption also
apply to portions of Securities called for redemption. The Trustee shall notify
the Company promptly of the Securities or portions of Securities to be redeemed.

            SECTION 3.03. Notice of Redemption. At least 30 days but not more
than 60 days before a date for redemption of Securities, the Company shall mail
a notice of redemption by first-class mail to each Holder of Securities to be
redeemed at such Holder's registered address.

                                    Page 36

<PAGE>

            The notice shall identify the Securities to be redeemed and shall
state:

          (1)  the redemption date;

          (2)  the redemption price or the method of calculating such redemption
               price pursuant to this Indenture;

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

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

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

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

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

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

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

            SECTION 3.04. Effect of Notice of Redemption. Once notice of
redemption is mailed, Securities called for redemption become due and payable on
the redemption date and at the redemption price stated in the notice. Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption
price stated in the notice, plus accrued interest to the redemption date
(subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date). Failure to give
notice or any defect in the notice to any Holder shall not affect the validity
of the notice to any other Holder.

            SECTION 3.05. Deposit of Redemption Price. At least one Business Day
prior to the redemption date, the Company shall deposit with the Paying Agent
(or, if the Company or a Subsidiary is the Paying Agent, shall segregate and
hold in trust) money sufficient to pay the redemption price of and accrued
interest on all Securities to be redeemed on that date other than Securities or
portions of Securities called for redemption which have been delivered by the
Company to the Trustee for cancelation.

            SECTION 3.06. Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part, the Company shall execute and the Trustee
shall authenticate for the Holder (at the Company's expense) a new Security
equal in principal amount to the unredeemed portion of the Security surrendered.

                                   ARTICLE 4

                                    Covenants

            SECTION 4.01. Payment of Securities. The Company shall promptly pay
the principal of and interest on the Securities on the dates and in the manner

                                    Page 37

<PAGE>

provided in the Securities and in this Indenture. Principal and interest shall
be considered paid on the date due if on such date the Trustee or the Paying
Agent holds in accordance with this Indenture immediately available funds
sufficient to pay all principal and interest then due.

            The Company shall pay interest on overdue principal at the rate
specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

            SECTION 4.02. SEC Reports. The Company shall file with the Trustee
and provide Securityholders, within 15 days after it files them with the SEC,
copies of its annual report and the information, documents and other reports
which the Company is required to file with the SEC pursuant to Section 13 or
15(d) of the Exchange Act (if any). Notwithstanding that the Company may not be
required to remain subject to the reporting requirements of Section 13 or 15(d)
of the Exchange Act applicable to a "foreign private issuer" (as such term is
defined in Rule 3b-4 under the Exchange Act), the Company shall file with the
SEC and furnish to the Trustee and Securityholders (i) within 120 days from the
end of each fiscal year, an annual report on Form 20-F (or any successor form)
containing the information required to be contained therein for such fiscal
year, and (ii) within 45 days from the end of each of the first three quarters
in each fiscal year, quarterly reports on Form 6-K containing unaudited
financial statements (including a balance sheet and statement of income, changes
in stockholders' equity and cash flows) and Management's Discussion and Analysis
of Financial Condition and Results of Operations for and as of the end of each
of such quarters (with comparable financial statements for such quarter of the
immediately preceding fiscal year). In each such report, the Company shall
disclose in reasonable detail its calculation of EBITDA for the twelve-month
period ended as of the end of such fiscal year or such fiscal quarter, as
applicable. The Company also shall comply with the other provisions of TIA ss.
314(a).

            SECTION 4.03. Limitation on Indebtedness. (a) The Company shall not
and shall not permit any Restricted Subsidiary to, Incur, directly or
indirectly, any Indebtedness except that the Company and its Subsidiary
Guarantors may Incur Indebtedness if, on the date of such Incurrence and after
giving effect thereto, the Consolidated Coverage Ratio exceeds 2.0 to 1.0.

                  (b) Notwithstanding the foregoing paragraph (a), the Company
            and its Restricted Subsidiaries may Incur, directly or indirectly,
            any or all of the following Indebtedness:

            (1) Indebtedness of the Company and the Subsidiary Guarantors
      Incurred pursuant to a working capital line of credit in an amount which,
      when added together with the amount of all other Indebtedness Incurred
      pursuant to this clause (1) and then outstanding does not exceed $15.0
      million;

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

            (3) the Securities;

            (4) Indebtedness outstanding on the Issue Date (other than
      Indebtedness described in clause (1), (2), (3) or (10) of this Section
      4.03(b));

            (5) Refinancing Indebtedness in respect of Indebtedness Incurred

                                    Page 38

<PAGE>

      pursuant to Section 4.03(a) or pursuant to clause (3), (4), this clause
      (5) or clause (8) below;

            (6) Indebtedness (A) in respect of performance, surety, appeal or
      similar bonds provided in the ordinary course of business, and (B) arising
      from agreements providing for indemnification, adjustment of purchase
      price or similar obligations, or from Guarantees or letters of credit,
      surety bonds or performance bonds securing any obligations of the Company
      or any of its Restricted Subsidiaries pursuant to such agreements, in any
      case Incurred in connection with the disposition of any business or assets
      of the Company or any of its Restricted Subsidiaries, including all or any
      interest in any Restricted Subsidiary, and not exceeding the gross
      proceeds therefrom, other than Guarantees of Indebtedness Incurred by any
      Person acquiring all or any portion of such business or assets of the
      Company or any of its Restricted Subsidiaries for the purpose of financing
      such acquisition;

            (7) Hedging Obligations consisting of Interest Rate Agreements or
      Currency Agreements directly related to Indebtedness permitted to be
      Incurred by the Company pursuant to this Indenture;

            (8) Purchase Money Indebtedness Incurred to finance the acquisition
      by the Company or a Restricted Subsidiary of additional Vessels or
      Shipping Business Assets; provided, however, that, at the date of such
      Incurrence, the amount of such Indebtedness shall not exceed 80% of the
      cost of acquiring such Vessel or such Shipping Business Assets, including
      the purchase price of such Vessel or such Shipping Business Assets under
      the Acquisition Contract in respect thereof plus any Ready for Sea Cost;

            (9) Indebtedness consisting of the Subsidiary Guarantee of a
      Subsidiary Guarantor and any Guarantee by a Subsidiary Guarantor of
      Indebtedness Incurred pursuant to clause (3) or (4) or pursuant to clause
      (5) to the extent the Refinancing Indebtedness Incurred thereunder
      directly or indirectly Refinances Indebtedness Incurred pursuant to clause
      (3) or (4);

            (10) Indebtedness Incurred by the Company or any Restricted
      Subsidiary pursuant to any IFC Loan Agreement in an aggregate principal
      amount which, when added together with the amount of all other
      Indebtedness Incurred pursuant to this clause (10) and then outstanding,
      does not exceed $40.0 million; and

            (11) Indebtedness of the Company, the Subsidiary Guarantors and
      other Restricted Subsidiaries in an aggregate principal amount which,
      together with all other Indebtedness of the Company outstanding on the
      date of such Incurrence (other than Indebtedness permitted by clauses (1)
      through (10) above or paragraph (a)), does not exceed $15.0 million;
      provided that the aggregate principal amount of Indebtedness that may be
      Incurred pursuant to this clause (11) by Restricted Subsidiaries that are
      not Subsidiary Guarantors shall not exceed $10.0 million at any time
      outstanding.

                  (c) Notwithstanding the foregoing, the Company shall not Incur
            any Indebtedness pursuant to Section 4.03(b) if the proceeds thereof
            are used, directly or indirectly, to Refinance any Subordinated
            Obligations unless such Indebtedness shall be subordinated to the
            Securities to at least the same extent as such Subordinated
            Obligations.

                  (d) For purposes of determining compliance with this Section
            4.03, (i) in the event that an item of Indebtedness meets the
            criteria of more than one of the types of Indebtedness described
            above, the Company, in its sole discretion, will classify such item

                                    Page 39

<PAGE>

            of Indebtedness in any manner that complies with this covenant and
            only be required to include the amount and type of such Indebtedness
            in one of the above clauses and (ii) an item of Indebtedness may be
            divided and classified in more than one of the types of
            Indebtedness.

            SECTION 4.04. Limitation on Restricted Payments. (a) The Company
shall not, and shall not permit any Restricted Subsidiary, directly or
indirectly, to make a Restricted Payment if at the time the Company or such
Restricted Subsidiary makes such Restricted Payment: (1) a Default shall have
occurred and be continuing (or would result therefrom); (2) the Company is not
able to Incur an additional $1.00 of Indebtedness pursuant to Section 4.03(a);
or (3) the aggregate amount of such Restricted Payment and all other Restricted
Payments since the Issue Date would exceed the sum of:

            (A) 50% of the Consolidated Net Income accrued during the period
      (treated as one accounting period) from the beginning of the fiscal
      quarter during which the Securities are originally issued to the end of
      the most recent fiscal quarter for which financial statements are publicly
      available prior to the date of such Restricted Payment (or, in case such
      Consolidated Net Income shall be a deficit, minus 100% of such deficit);

            (B) the aggregate Net Cash Proceeds received by the Company from the
      issuance or sale of its Capital Stock (other than Disqualified Stock)
      subsequent to the Issue Date (other than an issuance or sale to a
      Subsidiary of the Company and other than an issuance or sale to an
      employee stock ownership plan or to a trust established by the Company or
      any of its Subsidiaries for the benefit of their employees to the extent
      such issuance or sale is financed with proceeds of debt provided by the
      Company or any Subsidiary of the Company);

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

            (D) an amount equal to the sum of (i) the net reduction in
      Investments in Unrestricted Subsidiaries resulting from dividends,
      repayments of loans or advances or other transfers of assets, in each case
      to the Company or any Restricted Subsidiary from Unrestricted
      Subsidiaries, and (ii) the portion (proportionate to the Company's equity
      interest in such Subsidiary) of the fair market value of the net assets of
      an Unrestricted Subsidiary at the time such Unrestricted Subsidiary is
      designated a Restricted Subsidiary; provided, however, that the foregoing
      sum shall not exceed, in the case of any Unrestricted Subsidiary, the
      amount of Investments previously made (and treated as a Restricted
      Payment) by the Company or any Restricted Subsidiary in such Unrestricted
      Subsidiary; and

            (E) $7.5 million

                  (b) The provisions of Section 4.04(a) shall not prohibit:

                  (i) any Restricted Payment made by exchange for, or out of the
            proceeds of the substantially concurrent sale of, Capital Stock of
            the Company (other than Disqualified Stock and other than Capital
            Stock issued or sold to a Subsidiary of the Company or an employee
            stock ownership plan or to a trust established by the Company or any
            of its Subsidiaries for the benefit of their employees); provided,
            however, that (A) the amount of such Restricted Payment shall be

                                    Page 40

<PAGE>

            excluded in the calculation of the amount of Restricted Payments and
            (B) the Net Cash Proceeds from such sale shall be excluded from the
            calculation of amounts under Section 4.04(a)(3)(B);

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

                  (iii) dividends paid within 60 days after the date of
            declaration thereof if at such date of declaration such dividend
            would have complied with this covenant; provided, however, that at
            the time of payment of such dividend, no other Default shall have
            occurred and be continuing (or result therefrom); provided further,
            however, that such dividend shall be included in the calculation of
            the amount of Restricted Payments; or

                  (iv) the repurchase or other acquisition of shares of, or
            options to purchase shares of, common stock of the Company or any of
            its Subsidiaries from employees, former employees, directors or
            former directors of the Company or any of its Subsidiaries (or
            permitted transferees of such employees, former employees, directors
            or former directors), pursuant to the terms of agreements (including
            employment agreements) or plans (or amendments thereto) approved by
            the Board of Directors under which such individuals purchase or sell
            or are granted the option to purchase or sell, shares of such common
            stock; provided, however, that the aggregate amount of such
            repurchases and other acquisitions shall not exceed $250,000 in any
            calendar year; provided further, however, that such repurchases and
            other acquisitions shall be excluded in the calculation of the
            amount of Restricted Payments.

            SECTION 4.05. Limitation on Restrictions on Distributions from
Restricted Subsidiaries. The Company shall not, and shall not permit any
Restricted Subsidiary to, create or otherwise cause or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any
Restricted Subsidiary to (a) pay dividends or make any other distributions on
its Capital Stock to the Company or a Restricted Subsidiary or pay any
Indebtedness owed to the Company, (b) make any loans or advances to the Company
or (c) transfer any of its property or assets to the Company, except:

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

                  (ii) any encumbrance or restriction with respect to a
            Restricted Subsidiary pursuant to an agreement relating to any
            Indebtedness or Preferred Stock Incurred by such Restricted
            Subsidiary on or prior to the date on which such Restricted
            Subsidiary became a Restricted Subsidiary or was acquired by the
            Company (other than Indebtedness or Preferred Stock Incurred as
            consideration in, or to provide all or any portion of the funds or
            credit support utilized to consummate, the transaction or series of
            related transactions pursuant to which such Restricted Subsidiary
            became a Restricted Subsidiary or was acquired by the Company) and
            outstanding on such date;

                  (iii) any encumbrance or restriction pursuant to an agreement
            effecting a Refinancing of Indebtedness or Preferred Stock Incurred
            pursuant to an agreement referred to in clause (i) or (ii) of this

                                    Page 41

<PAGE>

            covenant or this clause (iii) or contained in any amendment to an
            agreement referred to in clause (i) or (ii) of this covenant or this
            clause (iii); provided, however, that the encumbrances and
            restrictions with respect to such Restricted Subsidiary contained in
            any such refinancing agreement or amendment are in the aggregate no
            less favorable to the Securityholders than encumbrances and
            restrictions with respect to such Restricted Subsidiary contained in
            such predecessor agreements;

                  (iv) any such encumbrance or restriction consisting of
            customary nonassignment provisions in leases governing leasehold
            interests to the extent such provisions restrict the transfer of the
            lease or the property leased thereunder;

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

                  (vi) any restriction with respect to a Restricted Subsidiary

            in full directly to the Trustee as Collateral and shall be received
            by the Trustee free of any Lien (other than the Lien of this

      such Restricted Subsidiary from one or more of such Asset Sales occurring
      on or after the Issue Date in any period of 12 consecutive months exceeds
      $12.5 million, then the Company shall or shall cause such Restricted
      Subsidiary to, within 30 days after the date Net Available Cash so
      received exceeds $12.5 million in any period of 12 consecutive months,
      apply an amount equal to such Net Available Cash either (i) toward a
      Permitted Excess Cash Use or (ii) treat (no later than the end of such

arm's-length dealings with a Person who is not such an Affiliate, (2) if such
Affiliate Transaction involves an amount in excess of $500,000, (i) are set
forth in writing and (ii) have been approved by a majority of the members of the

be fair, from a financial standpoint, to the Company and its Restricted
Subsidiaries.

            (b) The provisions of Section 4.08(a) shall not prohibit (i) any
      Permitted Investment or Restricted Payment permitted to be paid pursuant
      to Section 4.04, (ii) any issuance of securities, or other payments,

not permit any Restricted Subsidiary to, directly or indirectly, Incur or permit
to exist any Lien of any nature whatsoever on any of its properties (including

            (2) the circumstances and relevant facts regarding such Change of
      Control (including information with respect to pro forma historical
      income, cash flow and capitalization after giving effect to such Change of
      Control);

            (3) the repurchase date (which shall be no earlier than 30 days nor

      if any, to the Holders entitled thereto.

            (e) The Company shall comply, to the extent applicable, with the
      requirements of Section 14(e) of the Exchange Act and any other securities
      laws or regulations in connection with the repurchase of Securities
      pursuant to this Section 4.11. To the extent that the provisions of any

      Section 4.11, the Company shall comply with the applicable securities laws
      and regulations and shall not be deemed to have breached its obligations
      under this Section 4.11 by virtue thereof.

            SECTION 4.12. Future Subsidiary Guarantors. (a) To the extent that,
after the Issue Date, the Company acquires additional Vessels with the Escrowed
Property, each such Vessel shall be acquired by a Restricted Subsidiary, the
Company shall cause such Restricted Subsidiary to execute and deliver to the
Trustee a Guarantee Agreement pursuant to which such Restricted Subsidiary will
Guarantee payment of the Securities on the same terms and conditions as those
set forth in Article 10 of this Indenture (unless such Restricted Subsidiary is
already a Subsidiary Guarantor), to execute a Mortgage in favor of the Trustee
pursuant to which such acquired Vessel shall thereafter be a Mortgaged Vessel
for all purposes under this Indenture, to execute the related Security
Agreements and to satisfy such other conditions set forth in Section 3 of the
Escrow Agreement.

            (b) To the extent that, after the Issue Date, any Restricted
      Subsidiary that is not a Subsidiary Guarantor acquires any Mortgaged
      Vessel, the Company shall cause such Restricted Subsidiary to execute and
      deliver to the Trustee a Guarantee Agreement pursuant to which such
      Restricted Subsidiary will Guarantee payment of the Securities on the same
      terms and conditions as those set forth in Article 10 of this Indenture,
      to execute a Mortgage in favor of the Trustee pursuant to which such
      acquired Vessel shall thereafter be a Mortgaged Vessel for all purposes
      under this Indenture, to execute the related Security Agreements and to
      satisfy such other conditions set forth in Section 3 of the Escrow
      Agreement and the other Security Agreements.

            SECTION 4.13. Impairment of Security Interest. Other than in
connection with the creation of Permitted Liens, (a) the Company shall not, and
shall not permit any Restricted Subsidiary or Maritima SIPSA S.A. 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 Trustee and the Holders of the
Securities, and (b) the Company shall not, and shall not permit any Restricted
Subsidiary or Maritima SIPSA S.A. to, grant to any Person other than the
Trustee, for the benefit of the Trustee and the Holders of the Securities, any
interest whatsoever in any of the Collateral.

            SECTION 4.14. Application of Proceeds upon Sale or Loss of a
Mortgaged Vessel. (a) If either:

            (1) a Mortgaged Vessel or the Capital Stock of a Subsidiary
      Guarantor or a Pledgor is sold (other than the sale by a Pledgor of its
      Mortgaged Vessel or the sale of its Capital Stock to the Company or a
      Restricted Subsidiary) (which term shall not include the transfer of the
      operation of a Mortgaged Vessel pursuant to a bareboat charter with a
      purchase option, which is covered under Section 4.15) in compliance with
      Section 4.06(a) (the Mortgaged Vessel so sold or owned by the Subsidiary
      Guarantor or Pledgor whose Capital Stock is so sold being the "Sold
      Mortgaged Vessel"), or

            (2) an Event of Loss occurs at any time with respect to a Mortgaged

                                    Page 45

<PAGE>

      Vessel (the Mortgaged Vessel suffering such Event of Loss being the "Lost
      Mortgaged Vessel"),

then within 25 days after the date title of the Mortgaged Vessel passes to the
buyer (such date being the "Sale Date"), in the case of a sale, or within 25
days after the date such Event of Loss was deemed to have occurred (the "Loss
Date"), the Company shall give written notice (such date of notice being the
"Notification Date") to the Trustee whether it elects to redeem Securities in
connection with such sale or Event of Loss; provided, however, that if a Default
shall have occurred and be continuing on the Notification Date, the Company
shall redeem Securities in accordance with Section 4.14(c).

            Upon the receipt by the Company, a Subsidiary Guarantor or a Pledgor
of the Net Available Cash attributable to a Sold Mortgaged Vessel (other than
the receipt by a Pledgor of Net Available Cash attributable to the sale of its
Mortgaged Vessel or the sale of its Capital Stock to the Company or a Restricted
Subsidiary) or of the Net Event of Loss Proceeds attributable to a Lost
Mortgaged Vessel, such amounts shall be deposited with the Trustee pursuant to
Article 13 and shall constitute Collateral pending application in accordance
with Section 4.14(c).

            (b) If the Company elects to (or is required to) redeem Securities,
      the Company shall apply Net Available Cash or Net Event of Loss Proceeds,
      as the case may be, and any other cash, not later than 60 days after the
      date (the "Proceeds Receipt Date") of the receipt of such funds in an
      amount (the "Redemption Amount") at least equal to the Vessel Percentage
      applicable to the Sold Mortgaged Vessel as of the Sale Date or the Lost
      Mortgaged Vessel as of the Loss Date, as the case may be, multiplied by
      the principal amount of the Securities outstanding on the Sale Date or the
      Loss Date, as the case may be (provided, however, that if a Default shall
      have occurred and be continuing on the Notification Date, the amount
      required to be applied by the Company to redeem Securities shall equal the
      greater of such Redemption Amount and such Net Available Cash or Net Event
      of Loss Proceeds, as the case may be), to redeem such principal amount of
      Securities as can be redeemed at the Sale Redemption Price or the Loss
      Redemption Price, as the case may be.

            (c) On the redemption date attributable to a Sold Mortgaged Vessel
      or a Lost Mortgaged Vessel, the Trustee shall apply the applicable Net
      Available Cash or the applicable Net Event of Loss Proceeds then on
      deposit with it pursuant to Article 13 (together with any funds the
      Company delivers to the Trustee to the extent necessary to pay the Sale
      Redemption Price or the Loss Redemption Price for the Securities to be
      redeemed) to pay the Sale Redemption Price or the Loss Redemption Price to
      the Holders of Securities being redeemed. Upon the effectuation of any
      such redemption, all accrued and unpaid interest on the Securities so
      redeemed shall be deemed fully paid. To the extent that after the Sale
      Redemption Price or the Loss Redemption Price has been paid with respect
      to all Securities to be redeemed in respect of such Sold Mortgaged Vessel
      or Lost Mortgaged Vessel, as the case may be, any Net Available Cash or
      Net Event of Loss Proceeds attributable to such Sold Mortgaged Vessel or
      Lost Mortgaged Vessel remains on deposit with the Trustee and no Default
      has occurred and is continuing, such Net Available Cash or Net Event of
      Loss Proceeds may be released to the Company upon its request, free of the
      lien of this Indenture; provided, however, that such funds may only be
      used by the Company for a Permitted Excess Cash Use or to make an Excess
      Proceeds Offer.

            SECTION 4.15. Application of Proceeds upon Permitted Bareboat
Charter. (a) If the Company, a Subsidiary Guarantor or a Pledgor enters into a
Bareboat Charter with respect to a Mortgaged Vessel, then within 25 days after
title to such Mortgaged Vessel passes to the charterer at the end of the
bareboat charter period, the Company shall give written notice to the Trustee

                                    Page 46

<PAGE>

whether it elects to redeem Securities in connection with such Bareboat Charter;
provided, however, that if a Default shall have occurred and be continuing on
such Notification Date, the Company shall be required to redeem Securities in
accordance with Section 4.15(b).

            Upon receipt by the Company, a Subsidiary Guarantor or a Pledgor of
Bareboat Charter Funds, the Sale Equivalent Portion of such Bareboat Charter
Funds shall be deposited with the Trustee pursuant to Article 13 and shall
constitute Collateral pending application in accordance with Section 4.15(b) and
(c).

            (b) If the Company elects to redeem Securities, the Company shall
      apply the Sale Equivalent Portion of such Bareboat Charter Funds in
      respect of such Mortgaged Vessel plus accrued interest thereon, not later
      than 60 days after the date title to the relevant Mortgaged Vessel passes
      to the charterer at the end of the bareboat charter period, to redeem such
      principal amount of Securities as can be redeemed at the Sale Redemption
      Price. On the redemption date attributable to such Bareboat Charter, the
      Trustee shall apply the Sale Equivalent Portion of such Bareboat Charter
      Funds then on deposit with it (together with any funds the Company
      delivers to the Trustee to the extent necessary to pay the Sale Redemption
      Price for the Securities to be redeemed) to pay the Sale Redemption Price.

            (c) In the event the Company elects not to redeem Securities in
      respect of a Mortgaged Vessel subject to a Bareboat Charter, then by the
      date which is 12 months after the date title to such Mortgaged Vessel
      passes to the charterer at the end of the bareboat charter period, the
      Company shall tender, or cause to be tendered, to the Trustee as part of
      the Collateral one or more Vessels purchased using the Sale Equivalent
      Portion of such Bareboat Charter Funds in respect of such Mortgaged Vessel
      and then on deposit with the Trustee together with such funds otherwise
      available to the Company, provided that if such funds are insufficient to
      purchase Vessels they shall remain on deposit with the Trustee as
      Collateral pursuant to Article 13 for application in accordance with the
      terms and conditions of this Indenture. The Sale Equivalent Portion of
      Bareboat Charter Funds shall be available from time to time (including
      prior to the end of the Bareboat Charter period) to the Company pursuant
      to the terms of, and subject to the conditions of, this Indenture,
      including Article 13 hereof, to make any deposits in respect of, or to
      consummate the purchase of, one or more Vessels.

            On the date on which a Vessel is tendered to the Trustee as part of
the Collateral with respect to a Mortgaged Vessel that is subject to a Bareboat
Charter, the Company shall deliver to the Trustee, or shall cause the owner of
such Vessel, which shall be a Restricted Subsidiary of the Company or, if the
Princess Marina is subject to a Bareboat Charter prior to the date of the sale
by Maritima SIPSA S.A. of the Princess Marina to the Company or a Restricted
Subsidiary, Maritima SIPSA S.A., to deliver to the Trustee, as the case may be,
the following documents and certificates:

      the Bareboat Charter and the owner of the replacement Vessel is not a
      Wholly Owned Subsidiary;

            (ii) a fully executed Mortgage substantially in the form attached as
      Exhibit C to this Indenture (or a preliminary registration thereof,
      pending delivery of a copy of the Mortgage) and any related Security

      tendered to the Trustee (such Mortgage having been duly received for
      recording in the appropriate registry office or, if not practicable, then

                                    Page 47

<PAGE>

      subject to arrangements reasonably satisfactory to the Trustee having been
      made for such recording as soon as practicable, but in no event more than
      5 Business Days, after the date such Vessel is tendered to the Trustee);

            (iii) appropriate legal opinions substantially in the form attached
      as Exhibit E to the Escrow Agreement with respect to the Guarantee
      Agreement referred to in clause (i), the Mortgage referred in clause (ii)

      Guarantor), together with an Officers' Certificate with respect thereto;

            (v) copies, certified to be true and complete by an Officer of the
      Company, of any Charters related to such Vessel;

Proceeds Offers. (a) In the event that the Company elects, with respect to a
Sold Mortgaged Vessel or a Lost Mortgaged Vessel, not to redeem Securities as

Vessel; provided, however, that if at any time prior to the Vessel Tender Date
(as defined below), an Event of Default shall occur, the Company shall thereupon
become obligated to redeem Securities in accordance with the provisions of
Section 4.14. Net Available Cash or Net Event of Loss Proceeds, as the case may
be, attributable to such Sold Mortgaged Vessel or such Lost Mortgaged Vessel, as
the case may be, will be made available to the Company pursuant to the terms,
and subject to the conditions, of this Indenture, including Article 13 hereof,

Trustee after the tender of the Qualified Substitute Vessel, such funds shall be
released to the Company, free of the Lien of this Indenture, and the Company

            On the date on which a Qualified Substitute Vessel is tendered to
the Trustee as part of the Collateral (a "Vessel Tender Date") following a sale
of or an Event of Loss with respect to a Mortgaged Vessel, the Company shall
deliver to the Trustee, or shall cause the owner of such Qualified Substitute
Vessel, which shall be a Restricted Subsidiary of the Company or, if the

                                    Page 48

<PAGE>

      case, accrued interest (if any) to the date of purchase (an "Excess
      Proceeds Payment").

            (c) (1) Promptly, and in any event within 15 calendar days after the
      Company becomes obligated to make an Excess Proceeds Offer, the Company
      shall be obligated to deliver to the Trustee and send, by first-class mail
      to each Holder, a written notice stating that the Holder may elect to have
      his Securities purchased by the Company either in whole or in part
      (subject to prorating as hereinafter described in the event such Offer is
      oversubscribed) in integral multiples of $1,000 of principal amount, at
      the applicable purchase price. The notice shall specify a purchase date
      not less than 30 days nor more than 60 days after the date of such notice
      (the "Purchase Date") and shall contain such information concerning the
      business of the Company which the Company in good faith believes will
      enable such Holders to make an informed decision (which at a minimum will
      include (i) the most recently filed Annual Report on Form 20-F (including
      audited consolidated financial statements) of the Company, the most recent
      subsequently filed Current Report on Form 6-K of the Company, other than
      Current Reports describing Asset Sales otherwise described in the offering
      materials (or corresponding successor reports), (ii) a description of
      material developments in the Company's business subsequent to the date of
      the latest of such Reports, and (iii) if material, appropriate pro forma
      financial information) and all instructions and materials necessary to
      tender Securities pursuant to the Offer, together with the information
      contained in clause (3).

            (2) Not later than the date upon which written notice of an Excess
Proceeds Offer is delivered to the Trustee as provided above, the Company shall
deliver to the Trustee an Officers' Certificate as to (i) the amount of the
Excess Proceeds Offer (the "Offer Amount"), (ii) the allocation of the Net
Available Cash from the Asset Sales pursuant to which such Offer is being made
and (iii) the compliance of such allocation with the provisions of this
Indenture. By not later than 4:00 p.m. on such date, the Company shall also
irrevocably deposit with the Paying Agent (or, if the Company is acting as its
own Paying Agent, segregate and hold in trust) in Temporary Cash Investments,
maturing on the last day prior to the Purchase Date or on the Purchase Date if
funds are immediately available by open of business, an amount equal to the
Offer Amount to be held for payment in accordance with the provisions of this
Section. Upon the expiration of the period for which the Excess Proceeds Offer
remains open (the "Offer Period"), the Company shall deliver to the Trustee for
cancelation, by no later than 10:00 a.m. on the next Business Day, the
Securities or portions thereof which have been properly tendered to and are to
be accepted by the Company. The Paying Agent shall, on the Purchase Date, mail
or deliver payment to each tendering Holder in the amount of the purchase price.
In the event that the aggregate purchase price of the Securities delivered by
the Company to the Paying Agent is less than the Offer Amount, the Paying Agent
shall deliver the excess to the Company immediately after the expiration of the
Offer Period for application in accordance with this Section.

            (3) Holders electing to have a Security purchased shall be required
to surrender the Security, with an appropriate form duly completed, to the
Company at the address specified in the notice at least three Business Days
prior to the Purchase Date. Holders shall be entitled to withdraw their election
if the Trustee or the Company receives not later than one Business Day prior to
the Purchase Date, a telex, facsimile transmission or letter setting forth the
name of the Holder, the principal amount of the Security which was delivered for
purchase by the Holder and a statement that such Holder is withdrawing his
election to have such Security purchased. If at the expiration of the Offer
Period the aggregate principal amount of Securities surrendered by Holders
exceeds the Offer Amount, the Company shall select the Securities to be
purchased on a pro rata basis (with such adjustments as may be deemed
appropriate by the Company so that only Securities in denominations of $1,000,
or integral multiples thereof, shall be purchased). Holders whose Securities are

                                    Page 50

<PAGE>

purchased only in part shall be issued new Securities equal in principal amount
to the unpurchased portion of the Securities surrendered.

            (4) At the time the Company notifies the Trustee which Securities
are to be accepted for purchase and delivers the same to the Trustee, the
Company shall also deliver an Officers' Certificate stating that such Securities
(or portions thereof) are to be accepted by the Company pursuant to and in
accordance with the terms of this Section. A Security shall be deemed to have
been accepted for purchase at the time the Paying Agent, mails or delivers
payment therefor to the surrendering Holder.

            (d) The Company shall comply, to the extent applicable, with the
      requirements of Section 14(e) of the Exchange Act and any other securities
      laws or regulations in connection with the purchase of Securities pursuant
      to an Excess Proceeds Offer. To the extent that the provisions of any
      securities laws or regulations conflict with provisions of this Section
      4.16, the Company shall comply with the applicable securities laws and
      regulations and shall not be deemed to have breached its obligations under
      this Section 4.16 by virtue thereof.

            SECTION 4.17. Additional Amounts. (a) If the Company, any Subsidiary
Guarantor or any Pledgor (or any of their respective successors), as applicable,
is required by law or by the interpretation or administration thereof by the
relevant government authority or agency to withhold or deduct any amount for or
on account of any present or future tax, duty, levy, impost, assessment or other
governmental charge (including penalties, interest and other liabilities related
thereto) imposed or levied by or on behalf of the Bahamas, Bolivia, Liberia,
Paraguay, Argentina, Panama, Uruguay or Chile or by any authority or agency
therein or thereof having power to tax (or the jurisdiction of incorporation of
any successor of the Company, any Subsidiary Guarantor or any Pledgor)
(hereinafter "Taxes") from any payment made under or with respect to the
Securities, any Subsidiary Guarantee or any Mortgaged Vessel, as applicable, the
Company, such Subsidiary Guarantor or such Pledgor (or any of their respective
successors), as applicable, shall pay such additional amounts ("Additional
Amounts") as may be necessary so that the net amount received by each Holder
(including Additional Amounts) after such withholding or deduction will not be
less than the amount the Holder would have received if such Taxes had not been
withheld or deducted; provided, however, that no Additional Amounts shall be
payable with respect to payments made to a Holder (an "Excluded Holder") in
respect of a beneficial owner (i) which is subject to such Taxes by reason of
its being connected with the Bahamas, Bolivia, Liberia, Paraguay, Argentina,
Panama, Uruguay or Chile otherwise than by the mere holding of Securities or the
receipt of payments thereunder (or under the related Subsidiary Guarantee), (ii)
which presents any Security for payment of principal more than 60 days after the
later of (x) the date on which payment first became due and (y) if the full
amount payable has not been received by the Trustee on or prior to such due
date, the date on which, the full amount payable having been so received, notice
to that effect shall have been given to the Holders by the Trustee, except to
the extent that the Holder would have been entitled to such Additional Amounts
on presenting such Security for payment on the last day of the applicable 60-day
period, (iii) which failed to duly and timely comply with a reasonable, timely
request of the Company to provide information, documents or other evidence
concerning the Holder's nationality, residence, entitlement to treaty benefits,
identity or connection with the Bahamas, Bolivia, Liberia, Paraguay, Argentina,
Panama, Uruguay or Chile or any political subdivision or authority thereof, if
and to the extent that due and timely compliance with such request would have
reduced or eliminated any Taxes as to which Additional Amounts would have
otherwise been payable to such Holder but for this clause (iii), (iv) on account
of any estate, inheritance, gift, sale, transfer, personal property or other
similar Tax, (v) which is a fiduciary, a partnership or not the beneficial owner
of any payment on a Security, if and to the extent that any beneficiary or
settlor of such fiduciary, any partner in such partnership or the beneficial
owner of such payment (as the case may be) would not have been entitled to

                                    Page 51

<PAGE>

receive Additional Amounts with respect to such payment if such beneficiary,
settlor, partner or beneficial owner had been the Holder of such Security or
(vi) any combination of the foregoing numbered clauses of this proviso. The
Company, the Subsidiary Guarantors or the Pledgors (or any of their respective
successors), as applicable, shall make such withholding or deduction and remit
the full amount deducted or withheld to the relevant authority as and when
required in accordance with applicable law.

            (b) The Company, the Subsidiary Guarantors or the Pledgors (or any
      of their respective successor), as applicable, shall furnish to the
      Trustee, within 30 days after the date the payment of any Taxes is due
      pursuant to applicable law, certified copies of tax receipts evidencing
      such payment by the Company, the Subsidiary Guarantors or the Pledgors (or
      any of their respective successors), as applicable, in such form as
      provided in the normal course by the taxing authority imposing such Taxes
      and as is reasonably available to the Company, the Subsidiary Guarantors
      or the Pledgors (or any of their respective successors), as applicable.
      The Trustee shall make such evidence available to the Holders upon
      request. The Company, the Subsidiary Guarantors or the Pledgors (or any of
      their respective successors), as applicable, shall upon written request of
      each Holder (other than an Excluded Holder), reimburse each such Holder
      for the amount of (i) any Taxes so levied or imposed and paid by such
      Holder as a result of payments made under or with respect to the
      Securities, the Subsidiary Guarantees or a Mortgaged Vessel, as
      applicable, and (ii) any Taxes imposed with respect to any such
      reimbursement under the immediately preceding clause (i), but excluding
      any such Taxes on such Holder's net income, so that the net amount
      received by such Holder after such reimbursement will not be less than the
      net amount the Holder would have received if Taxes (other than such Taxes
      on such Holder's net income) on such reimbursement had not been imposed.

            (c) Whenever in this Indenture there is mentioned, in any context,
      (a) the payment of principal, (b) purchase prices in connection with a
      purchase of Securities, (c) interest or (d) any other amount payable on or
      with respect to any of the Securities, or any payment pursuant to the
      Subsidiary Guarantees or in respect of a Mortgaged Vessel such mention
      shall be deemed to include mention of the payment of Additional Amounts
      provided for in this section to the extent that, in such context,
      Additional Amounts are, were or would be payable in respect thereof.

            (d) The Company, the Subsidiary Guarantors or the Pledgors shall 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 Securities the Subsidiary Guarantees or a Mortgage or any other
      document or instrument in relation thereto, or the receipt of any payments
      with respect to the Securities, the Subsidiary Guarantees, or a Mortgage
      excluding such taxes, charges or similar levies imposed by any
      jurisdiction outside of the Bahamas, Bolivia, Liberia, Paraguay,
      Argentina, Panama, Uruguay or Chile, the jurisdiction of incorporation of
      any successor of the Company or any jurisdiction in which a paying agent
      is located, and hereby indemnifies the Holders for any such taxes paid by
      such Holders.

the laws of a Permitted Flag Jurisdiction; provided that the Trustee may release
the Mortgage and related Security Agreements to which any Mortgaged Vessel is
subject in connection with the reflagging of such Mortgaged Vessel in another
Permitted Flag Jurisdiction only if (i) the owner of the Mortgaged Vessel has
executed (A) a Mortgage and (B) the related Security Agreements with respect to
such Mortgaged Vessel, dated the date such Mortgaged Vessel shall be released
from the existing Mortgage and related Security Agreements to which it is
subject, which Mortgage and related Security Agreements shall be in appropriate

Permitted Flag Jurisdiction under which it is being reflagged if required by
applicable law in order to perfect the security interest therein created, as to
which the Trustee shall be entitled to rely on the Opinion of Counsel to the
Company with respect thereto; and (ii) arrangements reasonably satisfactory to
the Trustee have been made for recording the Mortgage referred to in clause (i)
above in the appropriate registry office of the Permitted Flag Jurisdiction

      personal jurisdiction over the Company or such Significant Subsidiary or
      any of their respective assets, and in a proceeding in which the Company
      or such Significant Subsidiary has made no official appearance) for the
      payment of money in excess of $5,000,000 or its foreign currency
      equivalent at the time (provided that the amount of such money judgment or
      decree shall be calculated net of any insurance coverage that the Company
      has determined in good faith is available in whole or in part with respect
      to such money judgment or decree) is entered against the Company or any
      Significant Subsidiary, remains outstanding for a period of 60 days
      following the entry of such judgment or decree and is not discharged,
      waived or the execution thereof stayed within 10 days after the notice
      specified below;

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

            (11) the security interest under the Security Agreements shall, at
      any time, cease to be in full force and effect for any reason (other than
      by operation of this Indenture and the Security Agreements) other than the
      satisfaction in full of all obligations under this Indenture and discharge
      of this Indenture or any security interest created thereunder shall be
      declared invalid or unenforceable or the Company or any Subsidiary
      Guarantor shall assert, in any pleading in any court of competent
      jurisdiction, that any such security interest is invalid or unenforceable.

            The foregoing will constitute Events of Default whatever the reason
for any such Event of Default and whether it is voluntary or involuntary or is
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body.

            The term "Bankruptcy Law" means Title 11, United States Code, or any
similar Federal or state law for the relief of debtors. The term "Custodian"
means any receiver, trustee, assignee, liquidator, custodian or similar official
under any Bankruptcy Law.

            A Default under clauses (4), (5), (6) or (9) is not an Event of
Default until the Trustee or the holders of at least 25% in principal amount of
the outstanding Securities notify the Company of the Default and the Company
does not cure such Default within the time specified after receipt of such
notice. Such notice must specify the Default, demand that it be remedied and
state that such notice is a "Notice of Default".

            The Company shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Event of Default under clause (6), (10) or (11) and any event which with the
giving of notice or the lapse of time would become an Event of Default under
clause (4), (5) or (9), its status and what action the Company is taking or
proposes to take with respect thereto.

            SECTION 6.02. Acceleration. If an Event of Default (other than an
Event of Default specified in Section 6.01(7) or (8) with respect to the
Company) occurs and is continuing, the Trustee by notice to the Company, or the
Holders of at least 25% in principal amount of the Securities then outstanding
by notice to the Company and the Trustee, may declare the principal of and
accrued but unpaid interest on all the Securities to be due and payable. Upon
such a declaration, such principal and interest shall be due and payable
immediately. If an Event of Default specified in Section 6.01(7) or (8) with

                                    Page 56

<PAGE>

respect to the Company occurs, the principal of and interest on all the
Securities shall ipso facto become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Securityholders.
The Holders of a majority in principal amount of the Securities then outstanding
by notice to the Trustee may rescind an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing
Events of Default have been cured or waived except nonpayment of principal or
interest that has become due solely because of acceleration. No such rescission
shall affect any subsequent Default or impair any right consequent thereto.

            SECTION 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Securities or to enforce the performance of
any provision of the Securities or this Indenture.

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

            SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in
principal amount of the Securities by notice to the Trustee may waive an
existing Default and its consequences except (a) a Default in the payment of the
principal of or interest on a Security or (b) a Default in respect of a
provision that under Section 9.02 cannot be amended without the consent of each
Securityholder affected. When a Default is waived, it is deemed cured, but no
such waiver shall extend to any subsequent or other Default or impair any
consequent right.

            SECTION 6.05. Control by Majority. The Holders of a majority in
principal amount of the Securities then outstanding may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or of exercising any trust or power conferred on the Trustee. However, the
Trustee may refuse to follow any direction that conflicts with law or this
Indenture or, subject to Section 7.01, that the Trustee determines is unduly
prejudicial to the rights of other Securityholders or would involve the Trustee
in personal liability; provided, however, that the Trustee may take any other
action deemed proper by the Trustee that is not inconsistent with such
direction. Prior to taking any action hereunder, the Trustee shall be entitled
to indemnification satisfactory to it in its sole discretion against all losses
and expenses caused by taking or not taking such action.

            SECTION 6.06. Limitation on Suits. Except to enforce the right to
receive payment of principal, premium (if any) or interest when due, no
Securityholder may pursue any remedy with respect to this Indenture or the
Securities unless:

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

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

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

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

                                    Page 57

<PAGE>

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

            A Securityholder may not use this Indenture to prejudice the rights
of another Securityholder or to obtain a preference or priority over another
Securityholder. In the event that the Definitive Securities are not issued to
any beneficial owner promptly after the Registrar has received a request from
the Holder of a Global Security to issue such Definitive Securities to such
beneficial owner of its nominee, the Company expressly agrees and acknowledges,
with respect to the right of any Holder to pursue a remedy pursuant to this
Indenture, the right of such beneficial holder of Securities to pursue such
remedy with respect to the portion of the Global Security that represents such
beneficial holder's Securities as if such Definitive Securities had been issued.

            SECTION 6.07. Rights of Holders To Receive Payment. Notwithstanding
any other provision of this Indenture, the right of any Holder to receive
payment of principal of and interest on the Securities held by such Holder, on
or after the respective due dates expressed in the Securities, or to bring suit
for the enforcement of any such payment on or after such respective dates, shall
not be impaired or affected without the consent of such Holder.

            SECTION 6.08. Collection Suit by Trustee. If an Event of Default
specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount then due and owing (together with interest on any
unpaid interest to the extent lawful) and the amounts provided for in Section
7.07.

            SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, its creditors or
its property and, unless prohibited by law or applicable regulations, may vote
on behalf of the Holders in any election of a trustee in bankruptcy or other
Person performing similar functions, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and its counsel, and any other amounts due the Trustee under Section
7.07.

            SECTION 6.10. Priorities. If the Trustee collects any money or
property pursuant to this Article 6, it shall pay out the money or property in
the following order:

            FIRST:  to holders of preferred maritime liens or other liens, if
      any, that arise by operation of law and that are prior to the Lien of
      this Indenture, the Mortgages or the Security Agreements;

            SECOND:  to the Trustee for amounts due under Section 7.07;

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

            FOURTH:  to the Company.

            The Trustee may fix a record date and payment date for any payment
to Securityholders pursuant to this Section. At least 15 days before such record
date, the Company shall mail to each Securityholder and the Trustee a notice

                                    Page 58

<PAGE>

that states the record date, the payment date and amount to be paid.

            SECTION 6.11. Undertaking for Costs. In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant. This Section does not apply to a suit by the
Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of
more than 10% in principal amount of the Securities.

            SECTION 6.12. Waiver of Stay or Extension Laws. The Company (to the
extent it may lawfully do so) shall not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and shall not hinder, delay or impede the execution
of any power herein granted to the Trustee, but shall suffer and permit the
execution of every such power as though no such law had been enacted.

                                   ARTICLE 7

                                     Trustee

            SECTION 7.01. Duties of Trustee. (a) If an Event of Default has
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and the Security Agreements and use the same
degree of care and skill in their exercise as a prudent Person would exercise or
use under the circumstances in the conduct of such Person's own affairs.

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

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

            (2) in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture and
      the Security Agreements. However, the Trustee shall examine the
      certificates and opinions to determine whether or not they conform to the
      requirements of this Indenture and the Security Agreements.

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

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

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

            (3) the Trustee shall not be liable with respect to any action it
      takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 6.05.

                                    Page 59

<PAGE>

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

                  (e) The Trustee shall not be liable for interest on any money
            received by it.

                  (f) Money held in trust by the Trustee shall be segregated, in
            a separate trust account from other funds.

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

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

            SECTION 7.02. Rights of Trustee. (a) The Trustee may rely on any
document believed by it to be genuine and to have been signed or presented by
the proper person. The Trustee need not investigate any fact or matter stated in
the document.

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

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

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

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

            SECTION 7.03. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar
or co-paying agent may do the same with like rights. However, the Trustee must
comply with Sections 7.10 and 7.11.

            SECTION 7.04. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture, the Security Agreements or the Securities, it shall not be
accountable for the Company's use of the proceeds from the Securities, and it
shall not be responsible for any statement of the Company in this Indenture, the

                                    Page 60

<PAGE>

Security Agreements or in any document issued in connection with the sale of the
Securities or in the Securities other than the Trustee's certificate of
authentication.

            SECTION 7.05. Notice of Defaults. If a Default occurs and is
continuing and if it is known to an officer in the corporate trust department of
the Trustee, the Trustee shall mail to each Securityholder notice of the Default
within 90 days after it occurs. Except in the case of a Default in payment of
principal of or interest on any Security (including payments pursuant to the
redemption provisions of such Security, if any), the Trustee may withhold the
notice if and so long as a committee of its Trust Officers in good faith
determines that withholding the notice is in the interests of Securityholders.
The Trustee shall have no obligation to notify the insurers of the Mortgaged
Vessels of any Default unless it has actual knowledge of such Default and a
reasonable period of time to act upon it.

            SECTION 7.06. Reports by Trustee to Holders. As promptly as
practicable after each June 1 beginning with the June 1 following the date of
this Indenture, and in any event prior to July 31 in each year, the Trustee
shall mail to each Securityholder a brief report dated as of June 1 that
complies with TIA ss. 313(a). The Trustee also shall comply with TIA ss. 313(b).

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

            SECTION 7.07. Compensation and Indemnity. The Company shall pay to
the Trustee from time to time reasonable compensation for its services. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred or made by it
(including costs of collection or costs of any sale or retaking incurred in
connection with the Trustee's exercise, as mortgagee, of its rights and remedies
under the Mortgages), in addition to the compensation for its services. Such
expenses shall include the reasonable compensation and expenses, disbursements
and advances of the Trustee's agents, counsel, accountants and experts. The
Company shall indemnify the Trustee and hold it harmless from and against any
and all damages, suits, actions, loss, liability or expense (including
attorneys' fees) incurred by it in connection with the administration of this
trust and the performance of its duties hereunder and under the Security
Agreements, including adequate advances against costs that may be incurred by
it. The Trustee shall notify the Company promptly of any claim for which it may
seek indemnity. Failure by the Trustee to so notify the Company shall not
relieve the Company of its obligations hereunder. The Company shall defend the
claim and the Trustee may have separate counsel and the Company shall pay the
fees and expenses of such counsel. The Company need not reimburse any expense or
indemnify against any loss, liability or expense incurred by the Trustee through
the Trustee's own willful misconduct, negligence or bad faith.

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

            The Company's payment obligations pursuant to this Section shall
survive the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of a Default specified in Section 6.01(7) or (8) with respect to
the Company, the expenses are intended to constitute expenses of administration
under the Bankruptcy Law.

            SECTION 7.08. Replacement of Trustee. The Trustee may resign at any

                                    Page 61

<PAGE>

time by so notifying the Company. The Holders of a majority in principal amount
of the Securities then outstanding may remove the Trustee by so notifying the
Trustee in writing and may appoint a successor Trustee. The Company shall remove
the Trustee if:

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

            (2) the Trustee is adjudged bankrupt or insolvent;

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

            (4) the Trustee otherwise becomes incapable of acting.

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

            A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.07 and shall be relieved of all further liability
hereunder for actions arising from and after such date of resignation or
removal.

            If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee or the Holders of
10% in principal amount of the Securities then outstanding may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

            If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

            Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under Section 7.07 shall continue for the
benefit of the retiring Trustee.

            SECTION 7.09. Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

            In case at the time such successor or successors by merger,
conversion or consolidation to the Trustee shall succeed to the trusts created
by this Indenture any of the Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificate of the Trustee shall have.

                                    Page 62

<PAGE>

            SECTION 7.10. Eligibility; Disqualification. The Trustee shall at
all times satisfy the requirements of TIA ss. 310(a). The Trustee shall have a
combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
ss. 310(b); provided, however, that there shall be excluded from the operation
of TIA ss. 310(b)(1) any indenture or indentures under which other securities or
certificates of interest or participation in other securities of the Company are
outstanding if the requirements for such exclusion set forth in TIA ss.
310(b)(1) are met.

            SECTION 7.11. Preferential Collection of Claims Against Company. The
Trustee shall comply with TIA ss. 311(a), excluding any creditor relationship
listed in TIA ss. 311(b). A Trustee who has resigned or been removed shall be
subject to TIA ss. 311(a) to the extent indicated.

                                   ARTICLE 8

                       Discharge of Indenture; Defeasance

            SECTION 8.01. Discharge of Liability on Securities; Defeasance. (a)
When (i) the Company delivers to the Trustee all outstanding Securities (other
than Securities replaced pursuant to Section 2.06) for cancelation or (ii) all
outstanding Securities have become due and payable, whether at maturity or as a
result of the mailing of a notice of redemption pursuant to Article 3 hereof and
the Company irrevocably deposits with the Trustee funds sufficient to pay at
maturity or upon redemption all outstanding Securities, including interest
thereon to maturity or such redemption date (other than Securities replaced
pursuant to Section 2.06), and if in either case the Company pays all other sums
payable hereunder by the Company, then this Indenture and the Security
Agreements shall, subject to Section 8.01(c), cease to be of further effect. The
Trustee shall acknowledge satisfaction and discharge of this Indenture and the
Security Agreements on demand of the Company accompanied by an Officers'
Certificate and an Opinion of Counsel and at the cost and expense of the
Company.

            (b) Subject to Sections 8.01(c) and 8.02, the Company at any time
      may terminate (i) all its obligations under the Securities and this
      Indenture ("legal defeasance option") or (ii) its obligations under
      Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12,
      4.13, 4.14, 4.15, 4.16, 4.17 and 4.20 and the operation of Sections
      6.01(4), 6.01(6), 6.01(7), 6.01(8), 6.01(9), 6.01(10) and 6.01(11) (but,
      in the case of Sections 6.01(7) and (8), with respect only to Significant
      Subsidiaries) and the limitations contained in Sections 5.01(a)(iii) and
      (iv) and 5.01(b), its obligations under Articles 11 and 13 and each
      Subsidiary Guarantor's obligations under Articles 10 and 12 and under the
      Security Agreements ("covenant defeasance option"). The Company may
      exercise its legal defeasance option notwithstanding its prior exercise of
      its covenant defeasance option.

            If the Company exercises its legal defeasance option, payment of the
Securities may not be accelerated because of an Event of Default with respect
thereto. If the Company exercises its covenant defeasance option, payment of the
Securities may not be accelerated because of an Event of Default specified in
Sections 6.01(4), 6.01(6), 6.01(7), 6.01(8), 6.01(9), 6.01(10) and 6.01(11)
(but, in the case of Sections 6.01(7) and (8), with respect only to Significant
Subsidiaries) or because of the failure of the Company to comply with Section
5.01(a)(iii) or (iv) or 5.01(b). If the Company exercises its legal defeasance
option or its covenant defeasance option, each Subsidiary Guarantor, if any,
shall be released from all its obligations with respect to its Subsidiary
Guarantee and under the Security Agreements including Article 12 and the Company
shall be released from its obligations under Articles 11 and 13 and under the
Security Agreements.

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

            (c) Notwithstanding clauses (a) and (b) above, the Company's
      obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.07 and 7.08
      and in this Article 8 shall survive until the Securities have been paid in
      full. Thereafter, the Company's obligations in Sections 7.07, 8.04 and
      8.05 shall survive.

            SECTION 8.02. Conditions to Defeasance. The Company may exercise its
legal defeasance option or its covenant defeasance option only if:

            (1) the Company irrevocably deposits in trust with the Trustee money
      or U.S. Government Obligations for the payment of principal of and
      interest on the Securities to maturity or redemption, as the case may be;

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

            (3) 123 days pass after the deposit is made and during the 123-day
      period no Default specified in Sections 6.01(7) or (8) with respect to the
      Company occurs which is continuing at the end of the period;

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

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

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

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

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

                                    Page 64

<PAGE>

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

            SECTION 8.03. Application of Trust Money. The Trustee shall hold in
trust money or U.S. Government Obligations deposited with it pursuant to this
Article 8. It shall apply the deposited money and the money from U.S. Government
Obligations through the Paying Agent and in accordance with this Indenture to
the payment of principal of and interest on the Securities.

            SECTION 8.04. Repayment to Company. The Trustee and the Paying Agent
shall promptly turn over to the Company upon request and in accordance with the
terms of this Indenture any excess money or securities held by them at any time.

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

            SECTION 8.05. Indemnity for Government Obligations. The Company
shall pay and shall indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against deposited U.S. Government Obligations or the
principal and interest received on such U.S. Government Obligations.

            SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is
unable to apply any money or U.S. Government Obligations in accordance with this
Article 8 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's and the Subsidiary
Guarantors' obligations under this Indenture, the Security Agreements and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to this Article 8 until such time as the Trustee or Paying Agent is
permitted to apply all such money or U.S. Government Obligations in accordance
with this Article 8; provided, however, that, if the Company has made any
payment of interest on or principal of any Securities because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money or U.S.
Government Obligations held by the Trustee or Paying Agent.

                                   ARTICLE 9

                                   Amendments

            SECTION 9.01. Without Consent of Holders. The Company, the
Subsidiary Guarantors, the Pledgors and the Trustee may amend this Indenture,
the Security Agreements or the Securities without notice to or consent of any
Securityholder:

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

            (2) to comply with Article 5;

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

            (4) to provide additional security for the Securities;

            (5) to add guarantees with respect to the Securities, including any

                                    Page 65

<PAGE>

      Subsidiary Guarantees;

            (6) to add to the covenants of the Company, a Restricted Subsidiary
      or a Pledgor for the benefit of the Holders or to surrender any right or
      power herein conferred upon the Company, a Subsidiary Guarantor or a
      Pledgor;

            (7) to comply with any requirements of the SEC in connection with
      qualifying, or maintaining the qualification of, this Indenture under the
      TIA;

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

            (9) to make any amendment to the provisions of this Indenture
      relating to the transfer and legending of Securities; provided, however,
      that (a) compliance with this Indenture as so amended would not result in
      Securities being transferred in violation of the Securities Act or any
      other applicable securities law and (b) such amendment does not materially
      and adversely affect the rights of Holders to transfer Securities.

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

            SECTION 9.02. With Consent of Holders. The Company, the Subsidiary
Guarantors, the Pledgors and the Trustee may amend this Indenture or the
Securities without notice to any Securityholder but with the written consent of
the Holders of at least a majority in principal amount of the Securities then
outstanding (including consents obtained in connection with a tender offer or
exchange for the Securities) and any past default or compliance with any
provision may also be waived with the consent of Holders of at least a majority
in principal amount of Securities then outstanding. However, without the consent
of each Securityholder affected thereby, an amendment may not:

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

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

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

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

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

            (6) make any changes in the Security Agreements or in Articles 10,
      11, 12 or 13 that adversely affect the Holders or would terminate the Lien
      of this Indenture or any Security Agreement on any property subject
      thereto or deprive the Holder of the security afforded by the Lien of this
      Indenture or the Security Agreements;

            (7) make any change in Section 6.04 or 6.07 or the second sentence
      of this Section;

            (8) make any change in any Subsidiary Guarantee that would adversely
      affect the Securityholders;

                                    Page 66

<PAGE>

            (9) make any change in Section 4.17 that adversely affects the
      rights of any Securityholder or amend the terms of the Securities or this
      Indenture in a way that would result in the loss of an exemption from any
      of the Taxes described therein.

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

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

            SECTION 9.03. Compliance with Trust Indenture Act. Every amendment
to this Indenture, the Security Agreements or the Securities shall comply with
the TIA as then in effect.

            SECTION 9.04. Revocation and Effect of Consents and Waivers. A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such Holder's
Security or portion of the Security if the Trustee receives the notice of
revocation before the date the amendment or waiver becomes effective. After an
amendment or waiver becomes effective, it shall bind every Securityholder. An
amendment or waiver becomes effective upon the execution of such amendment or
waiver by the Trustee.

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

            SECTION 9.05. Notation on or Exchange of Securities. If an amendment
changes the terms of a Security, the Trustee may require the Holder of the
Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder. Alternatively, if the Company or the Trustee so determines, the Company
in exchange for the Security shall issue and the Trustee shall authenticate a
new Security that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such
amendment.

            SECTION 9.06. Trustee To Sign Amendments. The Trustee shall sign any
amendment authorized pursuant to this Article 9 if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it. In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Section 7.01) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that such
amendment is authorized or permitted by this Indenture.

            SECTION 9.07. Payment for Consent. Neither the Company nor any
Affiliate of the Company shall, directly or indirectly, pay or cause to be paid

                                    Page 67

<PAGE>

any consideration, whether by way of interest, fee or otherwise, to any Holder
for or as an inducement to any consent, waiver or amendment of any of the terms
or provisions of this Indenture or the Securities unless such consideration is
offered to be paid to all Holders that so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.

                                   ARTICLE 10

                                   Guarantees

            SECTION 10.01. Guarantees. Each Subsidiary Guarantor hereby
unconditionally and irrevocably guarantees, jointly and severally, to each
Holder and to the Trustee and its successors and assigns (a) the full and
punctual payment of principal of and interest on the Securities when due,
whether at maturity, by acceleration, by redemption, by required repurchase or
otherwise, and all other monetary obligations of the Company and the Subsidiary
Guarantors under this Indenture and the Securities and of the Subsidiary
Guarantors under the Security Agreements and (b) the full and punctual
performance within applicable grace periods of all other obligations of the
Company and the Subsidiary Guarantors under this Indenture, the Security
Agreements and the Securities (all the foregoing being hereinafter collectively
called the "Obligations"). Each Subsidiary Guarantor further agrees that the
Obligations may be extended or renewed, in whole or in part, without notice or
further assent from such Subsidiary Guarantor and that such Subsidiary Guarantor
will remain bound under this Article 10 notwithstanding any extension or renewal
of any Obligation.

            Each Subsidiary Guarantor waives presentation to, demand of, payment
from and protest to the Company of any of the Obligations and also waives notice
of protest for nonpayment. Each Subsidiary Guarantor waives notice of any
default under the Securities or the Obligations. The obligations of each
Subsidiary Guarantor hereunder shall not be affected by (a) the failure of any
Holder or the Trustee to assert any claim or demand or to enforce any right or
remedy against the Company or any other Person under this Indenture, the
Security Agreements, the Securities or any other agreement or otherwise; (b) any
extension or renewal of any thereof; (c) any rescission, waiver, amendment or
modification of any of the terms or provisions of this Indenture, the Security
Agreements, the Securities or any other agreement; (d) the release of any
security held by any Holder or the Trustee for the Obligations or any of them;
(e) the failure of any Holder or the Trustee to exercise any right or remedy
against any other guarantor of the Obligations; or (f) subject to Section 10.06,
any change in the ownership of such Subsidiary Guarantor.

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

            Except as expressly set forth in Sections 8.01(b), 10.02 and 10.06,
the obligations of each Subsidiary Guarantor hereunder shall not be subject to
any reduction, limitation, impairment or termination for any reason, including
any claim of waiver, release, surrender, alteration or compromise, and shall not
be subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
Obligations or otherwise. Without limiting the generality of the foregoing, the
obligations of each Subsidiary Guarantor herein shall not be discharged or
impaired or otherwise affected by the failure of any Holder or the Trustee to
assert any claim or demand or to enforce any remedy under this Indenture, the
Security Agreements, the Securities or any other agreement, by any waiver or
modification of any thereof, by any default, failure or delay, willful or

                                    Page 68

<PAGE>

otherwise, in the performance of the obligations, or by any other act or thing
or omission or delay to do any other act or thing which may or might in any
manner or to any extent vary the risk of such Subsidiary Guarantor or would
otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law
or equity.

            Each Subsidiary Guarantor further agrees that its Subsidiary
Guarantee herein shall continue to be effective or be reinstated, as the case
may be, if at any time payment, or any part thereof, of principal of or interest
on any Obligation is rescinded or must otherwise be restored by any Holder or
the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

            In furtherance of the foregoing and not in limitation of any other
right which any Holder or the Trustee has at law or in equity against any
Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay
the principal of or interest on any Obligation when and as the same shall become
due, whether at maturity, by acceleration, by redemption or otherwise, or to
perform or comply with any other Obligation, each Subsidiary Guarantor hereby
promises to and will, upon receipt of written demand by the Trustee, forthwith
pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal
to the sum of (i) the unpaid amount of such Obligations, (ii) accrued and unpaid
interest on such Obligations (but only to the extent not prohibited by law) and
(iii) all other monetary Obligations of the Company or the Subsidiary Guarantors
to the Holders and the Trustee.

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

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

            SECTION 10.02. Limitation on Liability. Any term or provision of
this Indenture to the contrary notwithstanding, the maximum aggregate amount of
the Obligations guaranteed hereunder by any Subsidiary Guarantor shall not
exceed the maximum amount that can be hereby guaranteed without rendering this
Indenture, as it relates to such Subsidiary Guarantor, voidable under applicable
law relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally.

            SECTION 10.03. Successors and Assigns. This Article 10 shall be
binding upon each Subsidiary Guarantor and its successors and assigns and shall
enure to the benefit of the successors and assigns of the Trustee and the
Holders and, in the event of any transfer or assignment of rights by any Holder
or the Trustee, the rights and privileges conferred upon that party in this
Indenture, in the Security Agreements and in the Securities shall automatically
extend to and be vested in such transferee or assignee, all subject to the terms
and conditions of this Indenture.

            SECTION 10.04. No Waiver. Neither a failure nor a delay on the part
of either the Trustee or the Holders in exercising any right, power or privilege
under this Article 10 shall operate as a waiver thereof, nor shall a single or
partial exercise thereof preclude any other or further exercise of any right,
power or privilege. The rights, remedies and benefits of the Trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other

                                    Page 69

<PAGE>

rights, remedies or benefits which either may have under this Article 10 at law,
in equity, by statute or otherwise.

            SECTION 10.05. Modification. No modification, amendment or waiver of
any provision of this Article 10, nor the consent to any departure by any
Subsidiary Guarantor therefrom, shall in any event be effective unless the same
shall be in writing and signed by the Trustee, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given. No notice to or demand on any Subsidiary Guarantor in any case shall
entitle such Subsidiary Guarantor to any other or further notice or demand in
the same, similar or other circumstances.

            SECTION 10.06. Release of Subsidiary Guarantor. Upon the occurrence
of a sale or other disposition (including by way of consolidation or merger) of
a Subsidiary Guarantor or the sale or disposition of all or substantially all
the assets of such Subsidiary Guarantor (in each case other than to the Company
or an Affiliate of the Company), such Subsidiary Guarantor shall be deemed
released from all obligations under this Article 10 without any further action
required on the part of the Trustee or any Holder. At the request of the Company
and upon receipt of an Officers' Certificate, the Trustee shall execute and
deliver an appropriate instrument evidencing such release.

                                   ARTICLE 11

                               Pledged Collateral

            SECTION 11.01. Grant of Security Interest. To secure the full and
punctual payment when due and the full and punctual performance of the
Obligations, the Company and the Subsidiary Guarantors hereby grant to the
Trustee, for the benefit of the Trustee and the Holders, a security interest in
all its right, title and interest in and to the following, other than such of
the following which are released from the Lien of this Indenture pursuant to
Section 11.05 (the "Pledged Collateral"):

            (i) all shares of Capital Stock and other securities of the
      Subsidiary Guarantors now owned or hereafter acquired by the Company or
      the Subsidiary Guarantors, which on the date hereof are identified on
      Schedule I hereto (collectively, the "Pledged Shares"); provided, however,
      that (A) shares of Capital Stock and other securities will constitute
      Pledged Shares only to the extent that such Capital Stock and other
      securities can secure the Securities without Rule 3-10 or Rule 3-16 of
      Regulation S-X under the Securities Act ("Rule 3-10" and "Rule 3-16,"
      respectively) (or any other law, rule or regulation) requiring separate
      financial statements of such Subsidiary Guarantor to be filed with the SEC
      (or any other governmental regulatory agency); (B) in the event that
      either Rule 3-10 or Rule 3-16 requires or is amended, modified or
      interpreted by the SEC to require (or is replaced with another rule or
      regulation, or any other law, rule or regulation is adopted, which would
      require) the filing with the SEC (or any other governmental regulatory
      agency) of separate financial statements of any Subsidiary Guarantor due
      to the fact that such Subsidiary Guarantor's Capital Stock and other
      securities constitute Pledged Shares, then upon delivery to the Trustee of
      an Officer's Certificate identifying Pledged Shares in respect of a
      Subsidiary Guarantor that must be released from the Lien of this Indenture
      in order for the Company to avoid having to file separate financial
      statements for such Subsidiary Guarantor with the SEC, such Capital Stock
      and other securities shall automatically be deemed not to be Pledged
      Shares, but only to the extent necessary to not be subject to such
      requirement; and (C) in the event that either Rule 3-10 or Rule 3-16 is
      amended, modified or interpreted by the SEC to permit (or is replaced with
      another rule or regulation, or any other law, rule or regulation is
      adopted, which would permit) such Capital Stock and other securities to

                                    Page 70

<PAGE>

      constitute Pledged Shares without the filing with the SEC (or any other
      governmental regulatory agency) of separate financial statements of such
      Subsidiary Guarantor's, then such Capital Stock and other securities and
      shall automatically be deemed to be Pledged Shares, but only to the extent
      necessary to not be subject to any such financial statement requirement;

            (ii) all certificates representing any of the Pledged Shares; and

            (iii) all dividends, cash, instruments and other property and
      proceeds from time to time received, receivable or otherwise distributed
      in respect of or in exchange for any of the foregoing.

            SECTION 11.02. Delivery of Collateral. Any and all cash,
certificates or instruments representing or evidencing the Pledged Collateral
shall be delivered to and held by or on behalf of the Trustee and shall be in
suitable form for transfer by delivery, or shall be accompanied by duly executed
instruments of transfer or assignment in blank, all in form and substance
satisfactory to the Trustee. The Trustee shall have the right, at any time after
the occurrence and during the continuance of an Event of Default, in its
discretion and without notice to the Company, to transfer to or to register in
the name of the Trustee or any of its nominees any or all the Pledged
Collateral. In addition, the Trustee shall have the right at any time to
exchange certificates or instruments representing or evidencing Pledged
Collateral for certificates or instruments of different denominations.

            SECTION 11.03. Representations and Warranties. The Company and the
Subsidiary Guarantors hereby represent and warrant on the Issue Date as follows:

                  (a) Each of them is the record and beneficial owner of the
            applicable Pledged Shares described on Schedule I, free and clear of
            any Lien, except for the Lien created by this Indenture;

                  (b) Each of them has full corporate power, authority and legal
            right to pledge all the Pledged Collateral pledged by it pursuant to
            this Indenture.

                  (c) The Pledged Shares described on Schedule I have been duly
            authorized and are validly issued, fully paid and nonassessable.

                  (d) The pledge in accordance with the terms of this Indenture
            creates a valid and perfected first priority Lien on the Pledged
            Collateral securing the payment and performance of the Obligations.

                  (e) The shares described in Schedule I hereto represent 100.0%
            of the shares of Capital Stock of the Subsidiary Guarantors owned by
            the Company and the Subsidiary Guarantors.

                  (f) There are no existing options, warrants, calls or
            commitments of any character relating to any authorized and unissued
            Capital Stock of any Subsidiary Guarantor.

            SECTION 11.04. Further Assurances. The Company and the Subsidiary
Guarantors each agree that at any time and from time to time, at the expense of
the Company and the Subsidiary Guarantors, the Company will, or will cause the
Subsidiary Guarantors and Pledgors, promptly execute and deliver all further
instruments and documents and take all further action that may be necessary or
that the Trustee may reasonably request in order to perfect and protect any Lien
granted or purported to be granted hereby or to enable the Trustee to exercise
and enforce its rights and remedies hereunder with respect to any Pledged
Collateral. Without limiting the foregoing, the Company and the Subsidiary
Guarantors shall, subject to the limitations set forth in clause (i) of Section
11.01, (i) at the time of the issuance by a Subsidiary Guarantor of any shares
of Capital Stock after the Issue Date, deliver 100.0% of such shares to the

                                    Page 71

<PAGE>

Trustee as Pledged Collateral and provide to the Trustee a revised Schedule I,
and (ii) at the time of any release of Pledged Shares pursuant to Section 11.05,
provide to the Trustee a revised Schedule I. Any such revised Schedule shall
reflect any changes made necessary by the applicable acquisition or release, at
which time the Company and the Subsidiary Guarantors shall be deemed to make
their representations and warranties set forth in paragraphs (a) through (f) of
Section 11.03 with respect to such Schedule, as so revised.

            SECTION 11.05. Dividends; Voting Rights; Release of Collateral. (a)
As long as no Default shall have occurred and be continuing and until written
notice thereof from the Trustee to the Company, the Company and the Subsidiary
Guarantors shall be entitled to receive and retain all dividends and other
distributions paid in respect of the Pledged Shares owned by the Company and the
Subsidiary Guarantors; provided, however, that the provisions of this Indenture,
including Section 4.04, shall in all respects govern the Company's use or other
disposition of such cash or other property. Any cash dividends or distributions
delivered to or otherwise held by the Trustee pursuant to this Section 11.05,
and any other cash constituting Collateral delivered to the Trustee, shall be
invested, at the written direction of the Company, by the Trustee in Temporary
Cash Investments.

                  (b) Upon the occurrence and during the continuance of a
            Default and upon written notice thereof from the Trustee to the
            Company, the Trustee shall be entitled to receive and retain as
            Collateral all dividends paid and distributions made in respect of
            the Pledged Shares, whether so paid or made before or after any
            Default. Any such dividends shall, if received by the Company or the
            Subsidiary Guarantors, be received in trust for the benefit of the
            Trustee, be segregated from the other property or funds of the
            Company and the Subsidiary Guarantors, and be forthwith delivered to
            the Trustee as Collateral in the same form as so received (with any
            necessary endorsement).

                  (c) As long as no Default shall have occurred and be
            continuing and until written notice thereof from the Trustee to the
            Company, the Company and the Subsidiary Guarantors shall be entitled
            to exercise any and all voting and other consensual rights relating
            to Pledged Shares or any part thereof for any purpose; provided,
            however, that no vote shall be cast, and no consent, waiver or
            ratification given or action taken, which would be inconsistent with
            or violate any provision of this Indenture, the Security Agreements
            or the Securities.

                  (d) Upon the occurrence and during the continuance of a
            Default, all rights of the Company and the Subsidiary Guarantors to
            exercise the voting and other consensual rights that it would
            otherwise be entitled to exercise pursuant to Section 11.05(c) shall
            cease upon notice from the Trustee to the Company and the Subsidiary
            Guarantors and upon the giving of such notice all such rights shall
            thereupon be vested in the Trustee who shall thereupon have the sole
            right to exercise such voting and other consensual rights.

                  (e) In order to permit the Trustee to exercise the voting and
            other consensual rights which it may be entitled to exercise
            pursuant to Section 11.05(d), and to receive all dividends and
            distributions which it may be entitled to receive under Section
            11.05(b), the Company and the Subsidiary Guarantors shall, if
            necessary, upon written notice of the Trustee, from time to time
            execute and deliver to the Trustee such instruments as the Trustee
            may reasonably request.

                  (f) Notwithstanding anything to the contrary in this Article
            11, upon satisfaction by the Company of the conditions set forth in

                                    Page 72

<PAGE>

            Article 8 to its legal defeasance option, its covenant defeasance
            option or to the discharge of this Indenture, the Lien of this
            Indenture on all the Collateral shall terminate and all the Pledged
            Collateral shall be released without any further action on the part
            of the Trustee or any other Person. In addition, in connection with
            any release of a Subsidiary Guarantor pursuant to Section 10.06, the
            pledge of the Capital Stock of such Subsidiary Guarantor pursuant to
            this Article 11 shall be released and the security interest in the
            Mortgaged Collateral shall be released without any further action
            required on the part of the Trustee or any Holder. At the request of
            the Company, the Trustee shall execute and deliver appropriate
            instruments evidencing any release pursuant to this Section
            11.05(f).

            SECTION 11.06. Trustee Appointed Attorney-in-Fact. The Company and
the Subsidiary Guarantors each hereby appoint the Trustee as their
attorney-in-fact, with full authority in the place and stead of the Company and
the Subsidiary Guarantors, and in the name of the Company and the Subsidiary
Guarantors or otherwise, from time to time in the Trustee's discretion but only
after the occurrence and during the continuance of an Event of Default, to take
any action and to execute any instrument which the Trustee may deem necessary or
advisable in order to accomplish the purposes of this Article 11, including to
receive, endorse and collect all instruments made payable to the Company and the
Subsidiary Guarantors representing any dividend, interest payment or other
distribution in respect of the Pledged Collateral or any part thereof and to
give full discharge for the same. This power, being coupled with an interest, is
irrevocable.

            SECTION 11.07. Trustee May Perform. If the Company and the
Subsidiary Guarantors fail to perform any agreement contained in this Article
11, the Trustee may itself (but shall not be obligated to) perform, or cause
performance of, such agreement, and the expenses of the Trustee incurred in
connection therewith shall be payable by the Company under Section 7.07.

            SECTION 11.08. Trustee's Duties. The powers conferred on the Trustee
under this Article 11 are solely to protect its interest in the Pledged
Collateral and shall not impose any duty upon it to exercise any such powers.
Except for the safe custody of any Pledged Collateral in its possession and the
accounting for moneys actually received by it under this Article 11, the Trustee
shall have no duty as to any Pledged Collateral or as to the taking of any
necessary steps to preserve rights against prior parties or any other rights
pertaining to any Pledged Collateral.

            SECTION 11.09. Remedies upon Event of Default. If any Event of
Default shall have occurred and be continuing, the Trustee may exercise in
respect of the Pledged Collateral, in addition to other rights and remedies
provided for herein or otherwise available to it, all the rights and remedies
provided a secured party upon the default of a debtor under the Uniform
Commercial Code at that time, and the Trustee may also, without notice except as
specified below, sell the Pledged Collateral or any part thereof in one or more
parcels at public or private sale, at any exchange, broker's board or at any of
the Trustee's offices or elsewhere, for cash, on credit or for future delivery,
upon such terms as the Trustee may determine to be commercially reasonable, and
the Trustee or any Securityholder may be the purchaser of any or all the Pledged
Collateral so sold and thereafter hold the same, absolutely, free from any right
or claim of whatsoever kind. The Company and the Subsidiary Guarantors each
agree that, to the extent notice of sale shall be required by law, at least 10
days' notice to the Company and the Subsidiary Guarantors of the time and place
of any public sale or the time after which any private sale is to be made shall
constitute reasonable notification. The Trustee shall not be obligated to make
any sale of Pledged Collateral regardless of notice of sale having been given.
The Trustee may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without

                                    Page 73

<PAGE>

further notice, be made at the time and place to which it was so adjourned. The
Trustee shall incur no liability as a result of the sale of the Pledged
Collateral, or any part thereof, at any private sale conducted in a commercially
reasonable manner. The Company and the Subsidiary Guarantors each hereby waive
any claims against the Trustee arising by reason of the fact that the price at
which any Pledged Collateral may have been sold at such a private sale was less
than the price which might have been obtained at a public sale, even if the
Trustee accepts the first offer received and does not offer such Pledged
Collateral to more than one offeree.

            The Company and the Subsidiary Guarantors recognize that, by reason
of certain prohibitions contained in the Securities Act and applicable state
securities laws, the Trustee may be compelled, with respect to any sale of all
or any part of the Pledged Collateral, to limit purchasers to those who will
agree, among other things, to acquire such securities for their own account, for
investment, and not with a view to the distribution or resale thereof. The
Company and the Subsidiary Guarantors acknowledge and agree that any such sale
may result in prices and other terms less favorable to the seller than if such
sale were a public sale without such restrictions and, notwithstanding such
circumstances, agree that any such sale shall be deemed to have been made in a
commercially reasonable manner. The Trustee shall be under no obligation to
delay the sale of any of the Pledged Collateral for the period of time necessary
to permit the Company and the Subsidiary Guarantors to register such securities
for public sale under the Securities Act, or under applicable state securities
laws, even if the Subsidiary Guarantors or the Company would agree to do so.

            SECTION 11.10. Application of Proceeds. Upon the occurrence and
during the continuance of an Event of Default and after the acceleration of the
Securities pursuant to Section 6.02 (so long as such acceleration has not been
rescinded), any cash held by the Trustee as Pledged Collateral and all cash
proceeds received by the Trustee in respect of any sale of, collection from, or
other realization upon, all or any part of the Pledged Collateral, shall be
applied by the Trustee in the manner specified in Section 6.10.

            SECTION 11.11. Continuing Lien. Except as provided in Section 11.05,
this Indenture shall create a continuing Lien on the Pledged Collateral that
shall (i) remain in full force and effect until payment in full of the
Securities, (ii) be binding upon the Company and the Subsidiary Guarantors and
their successors and assigns and (iii) enure to the benefit of the Trustee and
its successors, transferees and assigns.

            SECTION 11.12. Certificates and Opinions. The Company shall comply
with (a) TIA ss. 314(b), relating to Opinions of Counsel regarding the Lien of
this Indenture and (b) TIA ss. 314(d), relating to the release of Pledged
Collateral from the Lien of this Indenture and Officers' Certificates or other
documents regarding fair value of the Pledged Collateral, to the extent such
provisions are applicable. Any certificate or opinion required by TIA ss. 314(d)
may be executed and delivered by an Officer of the Company to the extent
permitted by TIA ss. 314(d).

            SECTION 11.13. Additional Agreements. The Company and the Subsidiary
Guarantors each agree that, upon the occurrence and during the continuance of a
Default hereunder, each of them will, at any time and from time to time, upon
the written request of the Trustee, use its best efforts to take or to cause the
issuer of the Pledged Shares and any other securities distributed in respect of
the Pledged Shares (collectively with the Pledged Shares, the "Pledged
Securities") to take such action and prepare, distribute or file such documents,
as are required or advisable in the reasonable opinion of counsel for the
Trustee to permit the public sale of such Pledged Securities. The Company and
the Subsidiary Guarantors each further agree to indemnify, defend and hold
harmless the Trustee, each Holder, any underwriter and their respective
officers, directors, affiliates and controlling persons from and against all
loss, liability, expenses, costs of counsel (including reasonable fees and

                                    Page 74

<PAGE>

expenses of legal counsel to the Trustee), and claims (including the costs of
investigation) that they may incur insofar as such loss, liability, expense or
claim arises out of or is based upon any alleged untrue statement of a material
fact contained in any prospectus (or any amendment or supplement thereto) or in
any notification or offering circular, or arises out of or is based upon any
alleged omission to state a material fact required to be stated therein or
necessary to make the statements in any thereof not misleading, except insofar
as the same may have been caused by any untrue statement or omission based upon
information furnished in writing to the Company and the Subsidiary Guarantors or
the issuer of such Pledged Securities by the Trustee or any Holder expressly for
use therein. The Company and the Subsidiary Guarantors each further agree, upon
such written request referred to above, to use its best efforts to qualify, file
or register, or cause the issuer of such Pledged Securities to qualify, file or
register, any of the Pledged Securities under the Blue Sky or other securities
laws of such states as may be requested by the Trustee and keep effective, or
cause to be kept effective, all such qualifications, filings or registrations.
The Company and the Subsidiary Guarantors will bear all costs and expenses of
carrying out its obligations under this Section 11.13. The Company and the
Subsidiary Guarantors acknowledge that there is no adequate remedy at law for
failure by it to comply with the provisions of this Section 11.13 and that such
failure would not be adequately compensable in damages, and therefore agree that
their agreements contained in this Section 11.13 may be specially enforced.

                                   ARTICLE 12

                               Security Agreements

            SECTION 12.01. Collateral and Security Agreements. (a) To secure the
due and punctual payment of the Obligations, the Company, the Subsidiary
Guarantors, the Pledgors and the Trustee have entered or, under the
circumstances described in the Escrow Agreement, will enter, into the Security
Agreements. The Trustee and the Company hereby acknowledge and agree that the
Trustee holds the Collateral in trust for the benefit of the Trustee and the
Holders, in each case pursuant to the terms of the Security Agreements. Each
Holder, by accepting a Security, shall be deemed to have agreed to all the terms
and provisions of the Security Agreements.

            (b) As among the Holders, the Mortgaged Collateral shall be held for
      the equal and ratable benefit of such Holders without preference, priority
      or distinction of any thereof over any other.

            (c) Each Holder, by accepting a Security, agrees to all of the terms
      and provisions of the Security Agreements, as the same may be amended from
      time to time pursuant to the provisions of the Security Agreements and
      this Indenture, and authorizes and directs the Trustee to perform its
      obligations and exercise its rights under the Security Agreements in
      accordance therewith; provided, however, that if any provisions of the
      Security Agreements limit, qualify or conflict with the duties imposed by
      the provisions of the TIA, the TIA will control.

            SECTION 12.02. Recording; Annual Opinions. (a) The Company, the
Subsidiary Guarantors and the Pledgors will take or cause to be taken all action
required to maintain, preserve and protect the Lien on the Mortgaged Collateral
granted by the Security Agreements, including causing the Mortgages and any
other Security Agreement, instruments of further assurance and all amendments or
supplements thereto, to be promptly recorded, registered and filed and at all
times to be kept recorded, registered and filed, and will execute and file
statements and cause to be issued and filed statements, all in such manner and
in such places and at such times as are prescribed in the Escrow Agreement or in
this Indenture as may be required by law fully to preserve and protect the
rights of the Holders and the Trustee under this Indenture and the Security
Agreements to the Mortgaged Collateral.

                                    Page 75

<PAGE>

            The Company, the Subsidiary Guarantors and the Pledgors will from
time to time promptly pay and discharge all recording or filing fees, charges
and taxes relating to the filing or registration of this Indenture and the
Security Agreements, any amendments thereto and any other instruments of further
assurance.

            (b) The Company, the Subsidiary Guarantors and the Pledgors shall
      furnish to the Trustee:

                  (i) on the Issue Date or as soon as practicable after the
            execution and delivery of this Indenture, an Opinion of Counsel
            either (a) to the effect that, in the opinion of such Counsel, this
            Indenture and the assignment of the Collateral intended to be made
            by the Security Agreements and all other instruments of further
            assurance or assignment have been properly recorded, registered and
            filed (or proper provision has been made for such recording,
            registration and filing) to the extent necessary to make effective
            the Lien created by such Security Agreements and reciting the
            details of such action, and stating that as to the Lien created
            pursuant to such Security Agreements, such recordings, registerings
            and filings are the only recordings, registerings and filings
            necessary to give notice thereof and that no re-recordings,
            re-registerings or refilings are necessary to maintain such notice
            (other than as stated in such opinion), and further stating that all
            statements have been executed and filed (or proper provision has
            been made for such filing) that are necessary fully to preserve and
            protect the rights of the Holders and the Trustee with respect to
            the Lien under this Indenture and such Security Agreements, or (b)
            to the effect that, in the opinion of such counsel, no such action
            is necessary to perfect such Lien; and

                  (ii) on or before November 1 in each year beginning with
            November 1, 2005, an Opinion of Counsel, dated as of such date,
            either (a) to the effect that, in the opinion of such counsel, such
            action has been taken with respect to the recordings, registerings,
            filings, re-recordings, re-registerings and re-filings of this
            Indenture, the Security Agreements and all financing statements,
            continuation statements or other instruments of further assurance as
            is necessary to maintain the Lien of this Indenture and the Security
            Agreements and reciting with respect to such Lien the details of
            such action or referencing to prior Opinions of Counsel in which
            such details are given, and stating that all financing statements
            and continuation statements have been executed and filed that are
            necessary fully to preserve and protect the rights of the Holders
            and the Trustee hereunder and under the Security Agreements with
            respect to such Lien, or (b) to the effect that, in the opinion of
            such Counsel, no such action is necessary to maintain such Lien.

            SECTION 12.03. Disposition of Collateral Without Release. (a)
Notwithstanding the provisions of Section 12.04, so long as no Event of Default
shall have occurred and be continuing, the Company, the Subsidiary Guarantors
and the Pledgors, as the case may be, may, without any release or consent by the
Trustee:

                  (i) sell or otherwise dispose of any machinery, equipment,
            furniture, apparatus, tools or implements, materials or supplies or
            other similar property subject to the Lien of this Indenture and the
            Security Agreements, which may have become worn out or obsolete, not
            exceeding in aggregate value in any one calendar year $1,000,000, or
            which may constitute an Incidental Asset, upon substituting for the
            same other machinery, equipment, furniture, apparatus, tools or
            implements, materials or supplies or other similar property not

                                    Page 76

<PAGE>

            necessarily of the same character but of at least equal value to the
            Company as, and costing not less than the amount realized from, the
            Collateral disposed of, which shall forthwith become, without
            further action, subject to the Lien of this Indenture and the
            Security Agreements;

                  (ii) abandon, terminate, cancel, release or make alterations
            in or substitutions of any contracts subject to the Lien of this
            Indenture and any of the Security Agreements; provided, however,
            that any altered or substituted contracts shall forthwith, without
            further action, be subject to the Lien of this Indenture and the
            Security Agreements to the same extent as those previously existing;

                  (iii) surrender or modify any franchise, license or permit
            subject to the Lien of this Indenture and any of the Security
            Agreements which it may own or under which it may be operating;
            provided, however, that, after the surrender or modification of any
            such franchise, license or permit, the Company, the applicable
            Subsidiary Guarantor or the applicable Pledgor shall still, in the
            reasonable opinion of the Board of Directors of the Company, be
            entitled, under some other or without any franchise, license or
            permit, to conduct its business as it was operating immediately
            prior to such surrender or modification; or

                  (iv) demolish, dismantle, tear down, abandon or scrap any
            portion of the Mortgaged Collateral (other than a Mortgaged Vessel),
            if in the good faith opinion of the Board of Directors, as evidenced
            by a Board Resolution, such demolition, dismantling, tearing down,
            abandoning or scrapping is in the best interests of the Company and
            the fair market value and utility of the Collateral as an entirety,
            and the security for the Securities, will not thereby be impaired.

            (b) In the event that the Company, a Subsidiary Guarantor or a
      Pledgor has sold, exchanged or otherwise disposed of or proposes to sell,
      exchange or otherwise dispose of any portion of the Collateral which under
      the provisions of this Section 12.03 may be sold, exchanged or otherwise
      disposed of by the Company without any release or consent of the Trustee,
      and the Company requests the Trustee to furnish a written disclaimer,
      release or quitclaim of any interest in such property under this Indenture
      and the Security Agreements, the Trustee shall execute such an instrument
      upon delivery to the Trustee of (i) an Officers' Certificate by the
      Company reciting the sale, exchange or other disposition made or proposed
      to be made and describing in reasonable detail the property affected
      thereby, and stating that such property is property which by the
      provisions of this Section 12.03 may be sold, exchanged or otherwise
      disposed of or dealt with by the Company without any release or consent of
      the Trustee and (ii) an Opinion of Counsel stating that the sale, exchange
      or other disposition made or proposed to be made was duly taken by the
      Company, the Subsidiary Guarantor or the Pledgor in conformity with a
      designated subsection of Section 12.03(a) and that the execution of such
      written disclaimer, release or quitclaim is appropriate to confirm the
      propriety of such sale, disposition or other disposition under this
      Section 12.03.

            SECTION 12.04. Release of Mortgaged Collateral. In addition to its
rights under Section 12.03, the Company shall have the right, at any time and
from time to time, to sell, exchange or otherwise dispose of any of the
Mortgaged Collateral (other than Trust Moneys, which are subject to release from
the Lien of this Indenture and the Security Agreements as provided under Article
13), upon compliance with the requirements and conditions of this Section 12.04,
Section 4.06, Section 4.14 and Section 4.20, and the Trustee shall release the
same from the Lien of this Indenture and the Security Agreements upon receipt by
the Trustee of a Release Notice requesting such release and describing the

                                    Page 77

property to be so released, together with:

            (a) If the property to be released has a book value of at least
      $5,000,000, a Board Resolution requesting such release and authorizing an
      application to the Trustee therefor.

            (b) An Officers' Certificate, dated not more than 30 days prior to
      the date of the application for such release, in each case stating in
      substance as follows:

                  (i) that, in the opinion of the signers, the security afforded
            by this Indenture and the Security Agreements will not be impaired
            by such release in contravention of the provisions of this
            Indenture, and that if the Mortgaged Collateral to be released is
            not being replaced by comparable property, such Collateral has a
            book value equal to or less than $1,000,000 and is not necessary for
            the efficient operation of the Company's remaining property or in
            the conduct of the business of the Company;

                  (ii) that the Company, a Subsidiary Guarantor or a Pledgor has
            disposed of or will dispose of the Collateral so to be released for
            a consideration representing, in the opinion of the signers, its
            fair value, which consideration may consist of any one or more of
            the following, to the extent otherwise permitted by this Indenture:
            (A) cash or cash equivalents, (B) obligations secured by a purchase
            money Lien upon the property so to be released and (C) any other
            property or assets that, except as provided in Section 12.04(d),
            upon acquisition thereof by the Company, a Subsidiary Guarantor or a
            Pledgor would be subject to the Lien of this Indenture and the
            Security Agreements, and subject to no Lien other than Permitted
            Liens which, under the applicable provisions of the Security
            Agreements relating thereto, are permitted to be superior to the
            Lien of the Trustee herein and therein, all of such consideration to
            be briefly described in the certificate;

                  (iii) that no Event of Default has occurred and is continuing;

                  (iv) the fair value, in the opinion of the signers, of the
            property to be released at the date of such application for release;
            provided, however, that it shall not be necessary under this clause
            (iv) to state the fair value of any property whose fair value is
            certified in a certificate of an Appraiser under Section 12.04(c);

                  (v) whether the aggregate fair value of all Collateral to be

            Indenture and the Security Agreements pursuant to this Section 12.04
            since the commencement of the then current calendar year is 10% or

            property to be released is at least $100,000 and at least 1% of the
            aggregate principal amount of the Securities outstanding on the date
            of the application, and if such is the case, that a certificate of
            an Appraiser as to the fair value of the property to be released
            will be furnished under Section 12.04(c);

                  (vi) that if the Mortgaged Collateral to be released is only a
            portion of a Mortgaged Vessel, following such release, that the fair
            value of the Mortgaged Vessel (exclusive of the fair value of the
            released Mortgaged Collateral) shall not be less than the fair value
            of such Mortgaged Vessel (exclusive of the fair value of the
            released Mortgaged Collateral) prior to such release;

                  (vii) that all conditions precedent herein provided for

                                    Page 78

<PAGE>

            relating to the release of the Collateral in question have been
            complied with.

            (c) If (i) the fair value of the property to be released and of all
      other property released from the Lien of this Indenture and the Security
      Agreements pursuant to this Section 12.04 since the commencement of the
      then current calendar year, as shown by the certificate required by
      Section 12.04(b)(v), is 10% or more of the aggregate principal amount of
      the Securities outstanding on the date of the application, and (ii) the
      fair value of the Mortgaged Collateral to be so released, as shown by the
      certificate filed pursuant to Section 12.04(b)(v), is at least $25,000 and

      outstanding on the date of the application, a certificate of an Appraiser
      stating:

                  (1) the then fair value, in the opinion of the signer, of the
            property to be released; and

                  (2) that such release, in the opinion of the signer, will not
            impair the Lien of this Indenture or the Security Agreements in
            contravention of its terms.

            (d) The Net Available Cash, which will be paid to the Trustee
      (except Net Available Cash from any Asset Sale which is not required, or
      cannot be required through the passage of time or otherwise, to be used to
      repurchase or redeem or to make an offer to repurchase Securities
      hereunder); and, if any property other than cash, cash equivalents or
      obligations is included in the consideration received in connection with
      such Asset Sale, such instruments of conveyance, assignment and transfer,
      if any, as may be necessary, in the Opinion of Counsel to be given
      pursuant to Section 12.04(e), to subject to the Lien of this Indenture and
      the Security Agreements all the right, title and interest of the Company
      or the applicable Subsidiary Guarantor in and to such property.

            (e) An Opinion of Counsel substantially to the effect (i) that any
      obligation included in the consideration for any property so to be
      released and to be received by the Trustee pursuant to Section 12.04(d) is
      a valid and binding obligation enforceable in accordance with its terms
      and is effectively pledged under the Security Agreements, (ii) that any
      Lien granted by a purchaser to secure a purchase money obligation is a
      fully perfected Lien and such instrument granting such Lien is enforceable
      in accordance with its terms, (iii) either (x) that such instruments of
      conveyance, assignment and transfer as have been or are then delivered to
      the Trustee are sufficient to subject to the Lien of this Indenture and
      the applicable Security Agreements all the right, title and interest of
      the Company or the applicable Subsidiary Guarantor or Pledgor in and to
      any property, other than cash, cash equivalents and obligations, that is
      included in the consideration for the Mortgaged Collateral so to be
      released and is to be received by the Trustee pursuant to Section
      12.04(d), subject to no Lien other than Permitted Liens or (y) that no
      instruments of conveyance, assignment or transfer are necessary for such
      purpose, (iv) that the Company or the applicable Subsidiary Guarantor or
      Pledgor has corporate power to own all property included in the
      consideration for such release, and (v) that all conditions precedent
      herein and under the Security Agreements relating to the release of such
      Collateral have been complied with.

            (f) If the Mortgaged Collateral to be released is only a portion of
      a Mortgaged Vessel, an Opinion of Counsel relating to the Mortgaged Vessel
      confirming that after such release, the Lien of the Mortgage continues
      unimpaired as a perfected Lien upon the Mortgaged Vessel subject only to
      Permitted Liens.

                                    Page 79

            In connection with any release, the Company shall (i) execute,
deliver and record or file and obtain such instruments as the Trustee may
reasonably require, including amendments to the Security Agreements and this
Indenture, and (ii) deliver to the Trustee such evidence of the satisfaction of
the conditions included in this Indenture and the Security Agreements as the
Trustee may reasonably require.

            The Company shall exercise its rights under this Section by delivery
to the Trustee of a notice (each, a "Release Notice"), which shall refer to this
Section, describe with particularity the items of property proposed to be
covered by the release and be accompanied by a counterpart of the instruments
proposed to give effect to the release fully executed and acknowledged (if
applicable) by all parties thereto other than the Trustee and in form for
execution by the Trustee. Upon such compliance, the Company shall direct the
Trustee to execute, acknowledge (if applicable) and deliver to the Company such
counterpart within 10 Business Days after receipt by the Trustee of a Release
Notice and the satisfaction of the requirements of this Section.

            In case an Event of Default shall have occurred and be continuing,
the Company, a Subsidiary Guarantor or a Pledgor, while in possession of the
Mortgaged Collateral (other than cash, cash equivalents, securities and other
personal property held by, or required to be deposited or pledged with, the
Trustee hereunder or under any Security Agreement or with the trustee, mortgagee
or other holder of a Permitted Lien), may do any of the things enumerated in
this Section 12.04, if the Trustee in its discretion, or the Holders of a
majority in aggregate principal amount of the Securities outstanding, by
appropriate action of such Holders, shall consent to such action, in which event
any certificate filed under this Section shall omit the statement to the effect
that no Event of Default has occurred and is continuing. This paragraph shall
not apply, however, during the continuance of an Event of Default of the type
specified in Section 6.01(1) or 6.01(2).

            All cash or cash equivalents received by the Trustee pursuant to
this Section 12.04 shall be held by the Trustee, for the benefit of the Holders,
as Trust Moneys under Article 13 subject to application as therein provided. All
purchase money and other obligations received by the Trustee pursuant to this
Section 12.04 shall be held by the Trustee for the benefit of the Holders as
Mortgaged Collateral.

            SECTION 12.05. Eminent Domain, Expropriation and Other Governmental
Takings. If any of the Mortgaged Collateral is taken by eminent domain,
expropriation or other similar governmental taking (including a requisition for
hire which is not revoked within six months or a requisition for title) or is
sold pursuant to the exercise by any governmental authority of any right which
it may then have to purchase, or to designate a purchaser or to order a sale of,
all or any part of the Mortgaged Collateral, the Trustee shall release the
property so taken or purchased, but only upon receipt by the Trustee of the
following:

            (a) an Officers' Certificate stating that such property has been
      taken by eminent domain, expropriation or other similar governmental
      taking and the amount of the award therefor, or that such property has
      been sold pursuant to a right vested in a governmental authority to
      purchase, or to designate a purchaser, or order a sale of such property
      and the amount of the proceeds of such sale, that the amount of the
      proceeds of the property so sold is not less than the amount to which the
      Company or the applicable Subsidiary Guarantor or Pledgor is legally
      entitled under the terms of such right to purchase or designate a
      purchaser, or under the order or orders directing such sale, as the case
      may be, and that all conditions precedent herein provided for relating to
      such release have been complied with;

            (b) to hold as Trust Moneys, subject to the disposition thereof

                                    Page 80

<PAGE>

      pursuant to Article 13 hereof, the award for such property or the proceeds
      of such sale to the extent provided under the Security Agreements; and

            (c) an Opinion of Counsel substantially to the effect that:

                  (1) such property has been taken by eminent domain,
            expropriation or other similar governmental taking (including a
            requisition for hire which is not revoked within six months or a
            requisition for title) or has been sold pursuant to the exercise of
            a right vested in a governmental authority to purchase, or to
            designate a purchaser or order a sale of, such property; and

                  (2) the instruments and the award or proceeds of such sale
            which have been or are therewith delivered to and deposited with the
            Trustee conform to the requirements of this Indenture and the
            Security Agreements and that, upon the basis of such application,
            the Trustee is permitted by the terms hereof and of the Security
            Agreements to execute and deliver the release requested, and that
            all conditions precedent herein provided for relating to such
            release have been complied with.

            In any proceedings for the taking or purchase or sale of any part of
the Mortgaged Collateral, by eminent domain, expropriation or other similar
governmental taking or by virtue of any such right to purchase or designate a
purchaser or to order a sale, the Trustee may be represented by counsel who may
be counsel, at the Company's expense, for the Company.

            All cash received by the Trustee pursuant to this Section 12.05
shall be held by the Trustee as Trust Moneys under Article 13 subject to
application as therein provided. All purchase money and other obligations
received by the Trustee pursuant to this Section 12.05 shall be held by the
Trustee as Mortgaged Collateral subject to application as provided in Section
12.10.

            SECTION 12.06. Permitted Releases Not To Impair Lien; Trust
Indenture Act Requirements. The release of any Mortgaged Collateral from the
terms hereof and of the Security Agreements or the release of, in whole or in
part, the Liens created by the Security Agreements, will not be deemed to impair
the Lien on the Collateral in contravention of the provisions hereof if and to
the extent the Collateral or Liens are released pursuant to the applicable
Security Agreements and pursuant to the terms of this Article 12. The Trustee
and each of the Holders acknowledge that a release of Mortgaged Collateral or a
Lien strictly in accordance with the terms of the Security Agreements and of
this Article 12 will not be deemed for any purpose to be an impairment of the
Lien on the Mortgaged Collateral in contravention of the terms of this
Indenture. To the extent applicable, the Company and each obligor on the
Securities shall cause ss. 314(d) of the TIA relating to the release of property
or securities from the Lien hereof and of the Security Agreements to be complied
with. Any certificate or opinion required by ss. 314(d) of the TIA may be made
by an officer of the Company, except in cases which ss. 314(d) of the TIA
requires that such certificate or opinion be made by an independent person.

            SECTION 12.07. Suits To Protect the Mortgaged Collateral. Subject to
the provisions of the Security Agreements, the Trustee shall have power to
institute and to maintain such suits and proceedings as it may deem expedient to
prevent any impairment of the Mortgaged Collateral by any acts which may be
unlawful or in violation of any of the Security Agreements or this Indenture,
and such suits and proceedings as the Trustee, in its sole discretion, may deem
expedient to preserve or protect its interests and the interests of the Holders
in the Mortgaged Collateral (including power to institute and maintain suits or
proceedings to restrain the enforcement of or compliance with any legislative or
other governmental enactment, rule or order that may be unconstitutional or
otherwise invalid if the enforcement of, or compliance with, such enactment,

                                    Page 81

<PAGE>

rule or order would impair the Lien on the Mortgaged Collateral or be
prejudicial to the interests of the Holders or the Trustee).

            SECTION 12.08. Purchaser Protected. In no event shall any purchaser
in good faith of any property purported to be released hereunder be bound to
ascertain the authority of the Trustee to execute the release or to inquire as
to the satisfaction of any conditions required by the provisions hereof for the
exercise of such authority or to see to the application of any consideration
given by such purchaser or other transferee; nor shall any purchaser or other
transferee of any property or rights permitted by this Article 12 to be sold be
under obligation to ascertain or inquire into the authority of the Company or
the applicable Subsidiary Guarantor to make any such sale or other transfer.

            SECTION 12.09. Powers Exercisable by Receiver or Trustee. In case
the Mortgaged Collateral shall be in the possession of a receiver or trustee,
lawfully appointed, the powers conferred in this Article 12 upon the Company or
a Subsidiary Guarantor with respect to the release, sale or other disposition of
such property may be exercised by such receiver or trustee, and an instrument
signed by such receiver or trustee shall be deemed the equivalent of any similar
instrument of the Company or a Subsidiary Guarantor or of any officer or
officers thereof required by the provisions of this Article 12; and if the
Trustee shall be in the possession of the Mortgaged Collateral under any
provision of this Indenture, then such powers may be exercised by the Trustee.

            SECTION 12.10. Disposition of Obligations Received. All purchase
money and other obligations received by the Trustee under this Article shall be
held by the Trustee as a part of the Mortgaged Collateral. Upon payment in cash
or cash equivalents by or on behalf of the Company to the Trustee of the entire
unpaid principal amount of any such obligation, to the extent not constituting
Net Available Cash which may be required, through the passage of time or
otherwise, to be used to redeem or repurchase or to make an offer to redeem or
repurchase Securities, the Trustee shall release and transfer such obligation
and any mortgage securing the same upon receipt of any documentation that the
Trustee may reasonably require. Any cash or cash equivalents received by the
Trustee in respect of the principal of any such obligations shall be held by the
Trustee as Trust Moneys under Article 13 subject to application as therein
provided and as provided in the Security Agreements. Until the Securities are
accelerated, pursuant to Section 6.02, all interest and other income on any such
obligations, when received by the Trustee shall be paid to the Company from time
to time in accordance with Section 13.08. If the Securities have been
accelerated pursuant to Section 6.02, any such interest or other income not
theretofore paid, when collected by the Trustee, shall be applied by the Trustee
in accordance with Section 6.10.

            SECTION 12.11. Determinations Relating to Mortgaged Collateral. In
the event (i) the Trustee shall receive any written request from the Company, a
Subsidiary Guarantor or a Pledgor under any Security Agreement for consent or
approval with respect to any matter or thing relating to any Mortgaged
Collateral or the Company's, a Subsidiary Guarantor's or a Pledgor's obligations
with respect thereto or (ii) there shall be due to or from the Trustee under the
provisions of any Security Agreement any material performance or the delivery of
any material instrument or (iii) the Trustee shall become aware of any material
nonperformance by the Company, a Subsidiary Guarantor or a Pledgor of any
covenant or any material breach of any representation or warranty of the
Company, a Subsidiary Guarantor or a Pledgor set forth in any Security
Agreement, then, in each such event, the Trustee shall be entitled to hire, at
the sole reasonable cost and expense of the Company, experts, consultants,
agents and attorneys to advise the Trustee on the manner in which the Trustee
should respond to such request or render any requested performance or response
to such nonperformance or breach. The Trustee shall be fully protected in
accordance with Article 7 hereof in the taking of any action recommended or
approved by any such expert, consultant, agent or attorney and by
indemnification provided in accordance with Section 6.05 and other sections of

                                    Page 82

<PAGE>

this Indenture if such action is agreed to by Holders of a majority in principal
amount of the Securities pursuant to Section 6.05 and, the Trustee may, in its
sole discretion, prior to taking such action if such action could subject it to
environmental liabilities or taxation, require (i) direction from the Holders of
a majority in principal amount of the Securities in accordance with Section 6.05
hereof and (ii) indemnification in accordance with Section 6.05.

            SECTION 12.12. Release upon Termination of the Company's
Obligations. In the event that the Company delivers an Officers' Certificate
certifying that all the obligations under this Indenture, the Securities and the
Security Agreements have been satisfied and discharged by complying with the
provisions of Article 8 or by the payment in full of the Company's obligations
under the Securities, this Indenture and the Security Agreements, the Trustee
shall deliver to the Company a notice stating that the Trustee, on behalf of the
Holders, disclaims and gives up any and all rights it has in or to the Mortgaged
Collateral, and any rights it has under the Security Agreements.

            SECTION 12.13. Substitution of Mortgaged Vessel. In addition to its
rights under Sections 12.03 and Section 12.04, the Company shall have the right,
at any time and from time to time, to substitute any Mortgaged Vessel with a
Substitute Mortgaged Vessel, upon compliance with the requirements and
conditions of this Section 12.13 and Section 4.06 (if applicable) and Section
4.14. On the date on which a Substitute Mortgaged Vessel is tendered to the
Trustee as part of the Collateral (the "Vessel Substitution Date"), the Trustee
shall release such Mortgaged Vessel from the Lien of this Indenture and the
Security Agreements upon receipt by the Trustee of a Substitution Notice
requesting such substitution, describing the Mortgaged Vessel to be released and
the Substitute Mortgaged Vessel that the Company or a Restricted Subsidiary will
tender, or cause to be to be tendered, to the Trustee as Collateral in
substitution for the Mortgaged Vessel, together with:

            (a) If the Mortgaged Vessel to be released has a book value of at
      least $5,000,000, a Board Resolution requesting such release and
      authorizing an application to the Trustee to tender a Substitute Mortgaged
      Vessel in substitution therefor.

            (b) An Officers' Certificate, dated not more than 30 days prior to
      the date of the application for such release, in each case stating in
      substance as follows:

                  (i) that, in the opinion of the signers, the security afforded
            by this Indenture and the Security Agreements will not be impaired
            by such substitution in contravention of the provisions of this
            Indenture;

                  (ii) that no Event of Default has occurred and is continuing;

                  (iii) the Appraised Value of the Substitute Mortgaged Vessel
            at the Vessel Substitution Date is at least equal to the Appraised
            Value of the Mortgaged Vessel for which it is being substituted; and

                  (iv) that all conditions precedent herein provided for
            relating to the release of the Mortgaged Vessel and the tender of
            the Substitute Mortgaged Vessel in question have been complied with.

            (c) An Opinion of Counsel substantially to the effect (i) that such
      instruments of conveyance, assignment and transfer as have been or are
      then delivered to the Trustee are sufficient to subject the Substitute
      Mortgaged Vessel to the Lien of this Indenture and the applicable Security
      Agreements and to transfer all the right, title and interest of the
      Company or the applicable Subsidiary Guarantor or Pledgor in and to such
      Substitute Mortgaged Vessel to be received by the Trustee pursuant to this
      Section, subject to no Lien other than Permitted Liens, (ii) that the

      Officer of the Company, representing the Capital Stock of any Restricted

      Subsidiary Guarantor), together with an Officers' Certificate with respect
      thereto.

Agreements and this Indenture, and (ii) deliver to the Trustee such evidence of

of such Holders, shall consent to such action, in which event any certificate
filed under this Section shall omit the statement to the effect that no Event of
Default has occurred and is continuing. This paragraph shall not apply, however,
during the continuance of an Event of Default of the type specified in Section
6.01(1) or 6.01(2).

the Trustee for the benefit of the Holders of Securities as a part of the
Mortgaged Collateral, shall be held in United States dollars or U.S. dollar
denominated obligations, and, upon any entry upon or sale of the Mortgaged
Collateral or any part thereof pursuant to Article 6, said Trust Moneys shall be
applied in accordance with Section 6.10; but, prior to any such entry or sale,
all or any part of the Trust Moneys may be withdrawn, and shall be released,
paid or applied by the Trustee, from time to time as provided in Sections 13.02
to 13.05, inclusive, may be applied by the Trustee as provided in Section
13.07(b) and, if applicable, shall be released pursuant to Section 4.17.

            SECTION 13.02. Retirement of Securities. The Trustee shall apply
Trust Moneys from time to time to the payment of the principal of and interest
on any Securities, at final maturity or to the redemption thereof or the
purchase thereof upon tender or in the open market or at private sale or upon

following:

                  (a) a resolution of the Board of Directors directing the
            application pursuant to this Section of a specified amount of Trust
            Moneys (denominated in U.S. dollars) and in case any such moneys are

            and, in case any such moneys are to be applied to the purchase of
            any Securities, prescribing the method of purchase, the price or

                                    Page 85

<PAGE>

            prices to be paid and the maximum principal amount of any

            Indenture governing such purchase;

                  (b) additional cash (denominated in U.S. dollars) to the
            extent necessary to fund the entire payment amount or purchase price

            purpose;

                  (c) an Officers' Certificate, dated not more than five days
            prior to the date of the relevant application, stating

                        (i) that no Default exists; and

                        (ii) that all conditions precedent and covenants herein
                  provided for relating to such application of Trust Moneys have
                  been complied with; and

                  (d) an Opinion of Counsel stating that the documents and the
            cash or cash equivalents, if any, which have been or are therewith
            delivered to and deposited with the Trustee conform to the
            requirements of this Indenture and that all conditions precedent
            herein provided for relating to such application of Trust Moneys

            A resolution of the Board of Directors expressed to be irrevocable
directing the application of Trust Moneys under this Section to the payment of

such purpose. Such Trust Moneys and any cash deposited with the Trustee pursuant
to subsection (b) of this Section shall not, after compliance with the foregoing
provisions of this Section, be deemed to be part of the Collateral or Trust
Moneys.

within six months or a requisition for title) or sold pursuant to the exercise
by any governmental authority of any right which it may then have to purchase,
or to designate a purchaser or to order a sale of any part of the Mortgaged
Collateral, such Trust Moneys may be withdrawn by the Company or the applicable
Subsidiary Guarantor or Pledgor and shall be paid by the Trustee upon a request
by the Company to the Trustee by the proper officer or officers of the Company
or the applicable Subsidiary Guarantor or Pledgor to reimburse the Company or
the applicable Subsidiary Guarantor or Pledgor for expenditures made, or to pay
costs incurred, by the Company or the applicable Subsidiary Guarantor or Pledgor

      Moneys and setting forth:

            with such withdrawal of Trust Moneys, by the Company or the
            applicable Subsidiary Guarantor or Pledgor in a specified amount for
            the purpose of making certain repairs, rebuildings and replacements
            of the Mortgaged Collateral (including the acquisition of a
            Qualified Substitute Vessel), which shall be briefly described, and
            stating the fair value (which shall be substantiated by an
            Appraiser's certificate attached thereto) thereof to the Company at
            the date of the acquisition thereof by the Company, except that it
            shall not be necessary under this paragraph to state the fair value
            of any of such repairs, rebuildings or replacements that are
            separately described pursuant to paragraph (vi) of this subsection
            (I) and whose fair value is stated in the Appraiser's certificate
            under the following subsection (II) of this Section;

                  (ii) that no part of such expenditures, in any previous or
            then pending application, has been or is being made the basis for
            the withdrawal of any Trust Moneys pursuant to this Section 13.03;

                  (iii) that no part of such expenditures or costs has been paid
            out of either the proceeds of insurance upon any part of the
            Mortgaged Collateral not required to be paid to the Trustee under
            the Mortgage or any award for or the proceeds from any of the
            Mortgaged Collateral being taken not required to be paid to the
            Trustee under Section 12.05 hereof, as the case may be;

                  (iv) that there is no outstanding indebtedness or other

            construction of such repairs, rebuildings or replacements, or for
            labor, wages, materials or supplies in connection with the making
            thereof, which, if unpaid, might become the basis of a vendor's,
            mechanics', laborer's, materialmen's, statutory or other similar
            Lien upon any of such repairs, rebuildings or replacement, which
            Lien might, in the opinion of the signers of such certificate,
            materially impair the security afforded by such repairs, rebuildings
            or replacement;

                  (v) that the property to be repaired, rebuilt or replaced is
            necessary or desirable in the conduct of the Company's, the
            Subsidiary Guarantors' or the Pledgors' business;

                  (vi) whether any part of such repairs, rebuildings or
            replacements, within six months before the date of acquisition
            thereof by the Company, a Subsidiary Guarantor or a Pledgor, has
            been used or operated by others other than the Company, a Subsidiary
            Guarantor or a Pledgor in a business similar to that in which such
            property has been or is to be used or operated by the Company, a
            Subsidiary Guarantor or a Pledgor, and whether the fair value to the
            Company, a Subsidiary Guarantor or a Pledgor, at the date of such
            acquisition, of such part of such repairs, rebuildings or
            replacement is at least $25,000 and 1% of the aggregate principal
            amount of the outstanding Securities; and, if all such facts are
            present, such part of said repairs, rebuildings or replacements
            shall be separately described, and it shall be stated that an
            Appraiser's certificate as to the fair value to the Company of such
            separately described repairs, rebuildings or replacements will be
            furnished under the following subsection (II) of this Section

            of the property destroyed, damaged or taken; and

                  (ix) that all conditions precedent herein provided for
            relating to such withdrawal and payment have been complied with.

      described pursuant to the foregoing paragraph (vi) of subsection (I) of
      this Section, a certificate of an Appraiser stating the fair value to the
      Company, the Subsidiary Guarantors or the Pledgor, in such Appraiser's
      opinion, of such separately described maintenance or repairs at the date

            thereof are free and clear of all Liens prior to the Lien of this
            Indenture and the Security Agreements, except Permitted Liens to
            which the property so destroyed, damaged or taken shall have been
            subject at the time of such destruction, damage or taking; and

                  (iii) that all the Company's or the applicable Subsidiary
            Guarantor's or Pledgor's right, title and interest in and to said
            repairs, rebuilding or replacements, or combination thereof, are
            then subject to the Lien of this Indenture and the Security

      Section 13.03(a) or (b); provided, however, that notwithstanding the
      above, so long as no Default shall have occurred and be continuing, in the
      event that any insurance proceeds or award for such property or proceeds
      of such sale, in each case contemplated by Section 13.03(a), does not
      exceed $5,000,000, and, in the good faith estimate of the Company and the
      applicable Subsidiary Guarantor or Pledgor, such destruction or damage
      resulting in such insurance proceeds or such taking or sale resulting in
      such award does not detrimentally affect the value or use of the Mortgaged
      Collateral in any material respect, upon delivery to the Trustee of an
      Officers' Certificate to such effect, the Company may direct the Trustee
      and, upon such direction, the Trustee and the Company shall direct the
      insurer to release directly to the Company or the applicable Subsidiary
      Guarantor or Pledgor such insurance proceeds or award for such property or
      proceeds of such sale, free of the Lien hereof and of the Security
      Agreements.

            SECTION 13.04. Powers Exercisable Notwithstanding Event of Default.
In case Default shall have occurred and shall be continuing, the Company, while
in possession of the Mortgaged Collateral (other than cash, cash equivalents,
securities and other personal property held by, or required to be deposited or
pledged with, the Trustee hereunder or under the Security Agreements), may do
any of the things enumerated in Sections 13.02 and 13.03 if the Trustee in its
discretion, or the Holders of a majority in aggregate principal amount of the
outstanding Securities, by appropriate action of such Holders, shall consent to
such action, in which event any certificate filed under any of such Sections
shall omit the statement to the effect that no Default has occurred and is
continuing. This Section 13.04 shall not apply, however, during the continuance
of a Default of the type specified in Section 6.01(1) or 6.01(2).

            SECTION 13.05. Powers Exercisable by Trustee or Receiver. In case
the Mortgaged Collateral (other than any cash, cash equivalents, securities and
other personal property held by, or required to be deposited or pledged with,
the Trustee hereunder or under the Security Agreements) shall be in the
possession of a receiver or trustee lawfully appointed, the powers hereinbefore
in this Article 13 conferred upon the Company, the Subsidiary Guarantors and the
Pledgors with respect to the withdrawal or application of Trust Moneys may be
exercised by such receiver or trustee, in which case a certificate signed by
such receiver or trustee shall be deemed the equivalent of any Officers'
Certificate required by this Article 13. If the Trustee shall be in possession
of any of the Mortgaged Collateral hereunder or under the Security Documents,
such powers may be exercised by the Trustee in its discretion.

            SECTION 13.06. Disposition of Securities Retired. All Securities
received by the Trustee and for whose purchase Trust Moneys are applied under
this Article 13, if not otherwise canceled, shall be promptly canceled and
destroyed by the Trustee unless the Trustee shall be otherwise directed by
Company request. Upon destruction of any Securities, the Trustee shall issue a
certificate of destruction to the Company.

            SECTION 13.07. Investment and Use of Trust Moneys. (a) All or any
part of any Trust Moneys held by the Trustee hereunder (except such as may be
held for the account of any particular Securities), shall from time to time at
the direction of the Company be invested or reinvested by the Trustee in
Temporary Cash Investments. Unless a Default occurs and is continuing, any
interest on such Temporary Cash Investments (in excess of any accrued interest
paid at the time of purchase) which may be received by the Trustee shall be paid
periodically to the Company. Such Temporary Cash Investments shall be held by

                                    Page 90

<PAGE>

the Trustee as a part of the Mortgaged Collateral, subject to the same
provisions hereof as the cash used by it to purchase such cash equivalents. The
Trustee shall not be liable or responsible for any loss resulting from such
investments or sales except only for its own grossly negligent action, its own
grossly negligent failure to act or its own willful misconduct in complying with
this Section 13.07.

            (b) If the Company or any Subsidiary Guarantor or Pledgor shall fail
      to perform any of its covenants in this Indenture or under any Security
      Agreement, the Trustee may (but shall not be required to) at any time and
      from time to time, use, apply and advance any Trust Moneys held by it
      under this Article 13 or make advances to effect performance of any such
      covenant on behalf of the Company, such Subsidiary Guarantor or such
      Pledgor as contemplated by this Indenture or the Security Agreements;
      provided, however, that the Trustee shall not be required to make any such
      advances from its own funds; provided further, however, that all moneys so
      used or advanced by the Trustee, together (in the case of funds advanced
      by the Trustee) with interest at the rate borne by the Securities shall be
      repaid by the Company or the applicable Subsidiary Guarantor or Pledgor
      upon demand and such advances shall be secured under the Mortgages prior
      to the Securities. For repayment of all such advances the Trustee shall
      have the right to use and apply any Trust Moneys at any time held by it
      under Article 13 but no such use of Trust Moneys or advance shall relieve
      the Company, such Subsidiary Guarantor or such Pledgor from any Default.

                  (4) a statement as to whether or not, in the opinion of such
            individual, such covenant or condition has been complied with.

            SECTION 14.06. When Securities Disregarded. In determining whether
the Holders of the required principal amount of Securities have concurred in any
direction, waiver or consent, Securities owned by the Company or by any Person

common control with the Company shall be disregarded and deemed not to be

                                    Page 92

<PAGE>

outstanding, except that, for the purpose of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Securities which the Trustee knows are so owned shall be so disregarded. Also,
subject to the foregoing, only Securities outstanding at the time shall be
considered in any such determination.

            SECTION 14.07. Rules by Trustee, Paying Agent and Registrar. The

record date is a Legal Holiday, the record date shall not be affected.

            SECTION 14.09. Governing Law. This Indenture and the Securities

shall not have any liability for any obligations of the Company or any
Subsidiary Guarantor under the Securities or this Indenture or for any claim
based on, in respect of or by reason of such obligations or their creation. By
accepting a Security, each Securityholder shall waive and release all such
liability. The waiver and release shall be part of the consideration for the
issue of the Securities.

            SECTION 14.11. Successors. All agreements of the Company, the
Subsidiary Guarantors and Pledgors in this Indenture and the Securities shall
bind their successors. All agreements of the Trustee in this Indenture shall
bind its successors.

            SECTION 14.12. Multiple Originals. The parties may sign any number
of copies of this Indenture. Each signed copy shall be an original, but all of
them together represent the same agreement. One signed copy is enough to prove
this Indenture.

            SECTION 14.13. Table of Contents; Headings. The table of contents,
cross-reference sheet and headings of the Articles and Sections of this
Indenture have been inserted for convenience of reference only, are not intended

or provisions hereof.

            SECTION 14.14. Agent for Service; Submission to Jurisdiction; Waiver
of Immunities. By the execution and delivery of this Indenture, the Company and
each of the Pledgors and the Subsidiary Guarantors (i) acknowledges that it has,
by separate written instrument, irrevocably designated and appointed CT
Corporation System (and any successor entity), as its authorized agent upon
which process may be served in any suit or proceeding arising out of or relating
to this Indenture, the Securities or the Security Agreements that may be
instituted in any federal or state court in the State of New York, Borough of
Manhattan or brought by the Trustee (whether in its individual capacity or in
its capacity as Trustee hereunder), and acknowledges that CT Corporation System
has accepted such designation, (ii) submits to the jurisdiction of any such
court in any such suit or proceeding, and (iii) agrees that service of process
upon CT Corporation System and written notice of said service to the Company or
the applicable Pledgor or Subsidiary Guarantor, shall be deemed in every respect
effective service of process upon the Company or such Pledgor or Subsidiary
Guarantor, as the case may be, in any such suit or proceeding. The Company and
each of the Pledgors and the Subsidiary Guarantors further agree to take any and
all action, including the execution and filing of any and all such documents and
instruments, as may be necessary to continue such designation and appointment of
CT Corporation System in full force and effect so long as this Indenture shall
be in full force and effect.

            The Company and each of the Pledgors and the Subsidiary Guarantors
hereby irrevocably and unconditionally waive, to the fullest extent they may
legally effectively do so, any objection which they may now or hereafter have to
the laying of venue of any suit, action or proceeding arising out of or relating
to this Indenture, the Security Agreements or the Securities in any federal or
state court in the State of New York, Borough of Manhattan. The Company and each
of the Pledgors and the Subsidiary Guarantors hereto hereby irrevocably waives,
to the fullest extent permitted by law, the defense of an inconvenient forum to
the maintenance of such action or proceeding in any such court.

            To the extent either the Company or any of the Pledgors or the
Subsidiary Guarantors has or hereafter may acquire any immunity from
jurisdiction of any court or from any legal process (whether through service of
notice, attachment prior to judgment, attachment in aid of execution, execution
or otherwise) with respect to itself or its property, it hereby irrevocably
waives such immunity in Securities and the Security Agreements, to the extent
permitted by law.

            2. The Securities.

            2.1 (a) Form and Dating. The Initial Securities will be offered and
sold by the Company pursuant to a Purchase Agreement. The Initial Securities
will be resold initially only to (i) QIBs in reliance on Rule 144A under the
Securities Act ("Rule 144A") and (ii) Persons other than U.S. Persons (as
defined in Regulation S) in reliance on Regulation S under the Securities Act
("Regulation S"). Initial Securities may thereafter be transferred to, among
others, QIBs, IAIs and purchasers in reliance on Regulation S, subject to the
restrictions on transfer set forth herein. Initial Securities initially resold
pursuant to Rule 144A shall be issued initially in the form of one or more
permanent global Securities in definitive, fully registered form (collectively,
the "Rule 144A Global Security"); Initial Securities initially resold pursuant
to Regulation S shall be issued initially in the form of one or more permanent
global Securities in definitive, fully registered form (collectively, the
"Regulation S Global Security"); and Initial Securities to be resold to IAIs
shall be issued initially in the form of one or more permanent global Securities
in definitive, fully registered form (collectively, the "IAI Global Security"),
in each case without interest coupons and with the global securities legend and
the applicable restricted securities legend set forth in Exhibit 1 hereto, which
shall be deposited on behalf of the purchasers of the Initial Securities
represented thereby with the Securities Custodian and registered in the name of
the Depository or a nominee of the Depository, duly executed by the Company and
authenticated by the Trustee as provided in this Indenture. Beneficial ownership
interests in the Regulation S Global Security will be exchangeable for interests
in a Rule 144A Global Security, an IAI Global Security or a Definitive Security
only after the expiration of the Distribution Compliance Period.

            Beneficial interests in Regulation S Global Securities or IAI Global
Securities may be exchanged for interests in Rule 144A Global Securities if (1)
such exchange occurs in connection with a transfer of Securities in compliance
with Rule 144A and (2) the transferor of the beneficial interest in the
Regulation S Global Security or the IAI Global Security, as applicable, first
delivers to the Trustee a written certificate (in a form satisfactory to the
Trustee) to the effect that the beneficial interest in the Regulation S Global
Security or the IAI Global Security, as applicable, is being transferred to a
Person (a) who the transferor reasonably believes to be a QIB, (b) purchasing
for its own account or the account of a QIB in a transaction meeting the
requirements of Rule 144A, and (c) in accordance with all applicable securities
laws of the States of the United States and other jurisdictions.

            Beneficial interests in Regulation S Global Securities and Rule 144A
Global Securities may be exchanged for an interest in IAI Global Securities if
(1) such exchange occurs in connection with a transfer of the Securities in
compliance with an exemption under the Securities Act and (2) the transferor of
the Regulation S Global Security or Rule 144A Global Security, as applicable,
first delivers to the Trustee on behalf of the transferee a written certificate
(substantially in the form of Exhibit 2) to the effect that the Regulation S
Global Security or Rule 144A Global Security, as applicable, is being
transferred (x) to an "accredited investor" within the meaning of Rule
501(a)(1), (2), (3) or (7) under the Securities Act that is an institutional
investor acquiring the Securities for its own account or for the account of such

                                    Page 97

<PAGE>

an institutional accredited investor, for investment purposes and not with a
view to or for offer or sale in connection with any distribution in violation of
the Securities Act, (y) in accordance with all applicable securities laws of the
States of the United States and other jurisdictions and (z) in an aggregate
principal amount of Securities of no less than $250,000 or, if such transfer is
in an aggregate principal amount of Securities of less than $250,000, such
transferor shall also deliver to the Trustee an opinion of counsel acceptable to
the Company that such transfer is in compliance with the Securities Act.

            Beneficial interests in a Rule 144A Global Security or an IAI Global
Security may be transferred to a Person who takes delivery in the form of an
interest in a Regulation S Global Security, whether before or after the
expiration of the Distribution Compliance Period, only if the transferor first
delivers to the Trustee a written certificate (in the form provided in the
Indenture) to the effect that such transfer is being made in accordance with
Rule 903 or 904 of Regulation S or Rule 144 (if applicable).

            The Rule 144A Global Security, the IAI Global Security and the
Regulation S Global Security are collectively referred to herein as "Global
Securities". The aggregate principal amount of the Global Securities may from
time to time be increased or decreased by adjustments made on the records of the
Trustee and the Depository or its nominee as hereinafter provided.

            (b) Book-Entry Provisions. This Section 2.1(b) shall apply only to
a Global Security deposited with or on behalf of the Depository.

            The Company shall execute and the Trustee shall, in accordance with
this Section 2.1(b), authenticate and deliver initially one or more Global
Securities that (a) shall be registered in the name of the Depository for such
Global Security or Global Securities or the nominee of such Depository and (b)
shall be delivered by the Trustee to such Depository or pursuant to such
Depository's instructions or held by the Trustee as custodian for the
Depository.

            Members of, or participants in, the Depository ("Agent Members")
shall have no rights under this Indenture with respect to any Global Security
held on their behalf by the Depository or by the Trustee as the custodian of the
Depository or under such Global Security, and the Company, the Trustee and any
agent of the Company or the Trustee shall be entitled to treat the Depository as
the absolute owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depository
or impair, as between the Depository and its Agent Members, the operation of
customary practices of such Depository governing the exercise of the rights of a
holder of a beneficial interest in any Global Security.

            (c) Definitive Securities. Except as provided in this Section 2.1
or Section 2.3 or 2.4, owners of beneficial interests in Global Securities shall
not be entitled to receive physical delivery of Definitive Securities.

            2.2 Authentication. The Trustee shall authenticate and deliver: (1)
on the Issue Date, an aggregate principal amount of $180.0 million 9% First
Preferred Ship Mortgage Notes due 2014, and (2) Exchange Securities or Private
Exchange Securities for issue only in a Registered Exchange Offer or a Private
Exchange, respectively, pursuant to a Registration Rights Agreement, for a like
principal amount of Initial Securities, in each case upon a written order of the
Company signed by two Officers or by an Officer and either an Assistant
Treasurer or an Assistant Secretary of the Company. Such order shall specify the
amount of the Securities to be authenticated and the date on which the original
issue of Securities is to be authenticated and whether the Securities are to be
Initial Securities, Exchange Securities or Private Exchange Securities. The
aggregate principal amount of Securities outstanding at any time may not exceed

                                    Page 98

<PAGE>

$180,000,000 except as provided in Section 2.06 of this Indenture.

            2.3 Transfer and Exchange.

            Transfer and Exchange of Definitive Securities. When Definitive
Securities are presented to the Registrar with a request:

                        (x)   to register the transfer of such Definitive
                              Securities; or

                        (y)   to exchange such Definitive Securities for an
                              equal principal amount of Definitive Securities of
                              other authorized denominations,

the Registrar shall register the transfer or make the exchange as requested if
its reasonable requirements for such transaction are met; provided, however,
that the Definitive Securities surrendered for transfer or exchange:

                  (i) shall be duly endorsed or accompanied by a written
      instrument of transfer in form reasonably satisfactory to the Company and
      the Registrar, duly executed by the Holder thereof or its attorney duly
      authorized in writing; and

                  (ii) if such Definitive Securities are required to bear a
      restricted securities legend, they are being transferred or exchanged
      pursuant to an effective registration statement under the Securities Act,
      pursuant to Section 2.3(b) or pursuant to clause (A), (B) or (C) below,
      and are accompanied by the following additional information and documents,
      as applicable:

                        (A) if such Definitive Securities are being delivered to
            the Registrar by a Holder for registration in the name of such
            Holder, without transfer, a certification from such Holder to that
            effect; or

                        (B) if such Definitive Securities are being transferred
            to the Company, a certification to that effect; or

                        (C) if such Definitive Securities are being transferred
            (x) pursuant to an exemption from registration in accordance with
            Rule 144A, Regulation S or Rule 144 under the Securities Act; or (y)
            in reliance upon another exemption from the requirements of the
            Securities Act: (i) a certification to that effect (in the form set
            forth on the reverse of the Security) and (ii) if the Company so
            requests, an opinion of counsel or other evidence reasonably
            satisfactory to it as to the compliance with the restrictions set
            forth in the legend set forth in Section 2.3(e)(i).

            Restrictions on Transfer of a Definitive Security for a Beneficial
Interest in a Global Security. A Definitive Security may not be exchanged for a
beneficial interest in a Rule 144A Global Security, an IAI Global Security or a
Regulation S Global Security except upon satisfaction of the requirements set
forth below. Upon receipt by the Trustee of a Definitive Security, duly endorsed
or accompanied by appropriate instruments of transfer, in form satisfactory to
the Trustee, together with:

                  (i) certification, in the form set forth on the reverse of the
      Security, that such Definitive Security is either (A) being transferred to
      a QIB in accordance with Rule 144A, (B) being transferred to an IAI or (C)
      being transferred after expiration of the Distribution Compliance Period
      by a Person who initially purchased such Security in reliance on
      Regulation S to a buyer who elects to hold its interest in such Security
      in the form of a beneficial interest in the Regulation S Global Security;

                                    Page 99

<PAGE>

      and

                  (ii) written instructions directing the Trustee to make, or to
      direct the Securities Custodian to make, an adjustment on its books and
      records with respect to such Rule 144A Global Security (in the case of a
      transfer pursuant to clause (b)(i)(A)), IAI Global Security (in the case
      of a transfer pursuant to clause (b)(i)(B)) or Regulation S Global
      Security (in the case of a transfer pursuant to clause (b)(i)(C)) to
      reflect an increase in the aggregate principal amount of the Securities
      represented by the Rule 144A Global Security, IAI Global Security or
      Regulation S Global Security, as applicable, such instructions to contain
      information regarding the Depository account to be credited with such
      increase,

then the Trustee shall cancel such Definitive Security and cause, or direct the
Securities Custodian to cause, in accordance with the standing instructions and
procedures existing between the Depository and the Securities Custodian, the
aggregate principal amount of Securities represented by the Rule 144A Global
Security, IAI Global Security or Regulation S Global Security, as applicable, to
be increased by the aggregate principal amount of the Definitive Security to be
exchanged and shall credit or cause to be credited to the account of the Person
specified in such instructions a beneficial interest in the Rule 144A Global
Security, IAI Global Security or Regulation S Global Security, as applicable,
equal to the principal amount of the Definitive Security so canceled. If no Rule
144A Global Securities, IAI Global Securities or Regulation S Global Securities,
as applicable, are then outstanding, the Company shall issue and the Trustee
shall authenticate, upon written order of the Company in the form of an
Officers' Certificate of the Company, a new Rule 144A Global Security, IAI
Global Security or Regulation S Global Security, as applicable, in the
appropriate principal amount.

            Transfer and Exchange of Global Securities.

                  (i) The transfer and exchange of Global Securities or
      beneficial interests therein shall be effected through the Depository, in
      accordance with this Indenture (including applicable restrictions on
      transfer set forth herein, if any) and the procedures of the Depository
      therefor. A transferor of a beneficial interest in a Global Security shall
      deliver to the Registrar a written order given in accordance with the
      Depository's procedures containing information regarding the participant
      account of the Depository to be credited with a beneficial interest in the
      Global Security. The Registrar shall, in accordance with such
      instructions, instruct the Depository to credit to the account of the
      Person specified in such instructions a beneficial interest in the Global
      Security and to debit the account of the Person making the transfer the
      beneficial interest in the Global Security being transferred.

                  (ii) If the proposed transfer is a transfer of a beneficial
      interest in one Global Security to a beneficial interest in another Global
      Security, the Registrar shall reflect on its books and records the date
      and an increase in the principal amount of the Global Security to which
      such interest is being transferred in an amount equal to the principal
      amount of the interest to be so transferred, and the Registrar shall
      reflect on its books and records the date and a corresponding decrease in
      the principal amount of the Global Security from which such interest is
      being transferred.

                  (iii) Notwithstanding any other provisions of this Appendix
      (other than the provisions set forth in Section 2.4), a Global Security
      may not be transferred as a whole except by the Depository to a nominee of
      the Depository or by a nominee of the Depository to the Depository or
      another nominee of the Depository or by the Depository or any such nominee
      to a successor Depository or a nominee of such successor Depository.

                  (iv) In the event that a Global Security is exchanged for
      Definitive Securities pursuant to Section 2.4 of this Appendix, prior to
      the consummation of a Registered Exchange Offer or the effectiveness of a
      Shelf Registration Statement with respect to such Securities, such
      Securities may be exchanged only in accordance with such procedures as are
      substantially consistent with the provisions of this Section 2.3
      (including the certification requirements set forth on the reverse of the
      Initial Securities intended to ensure that such transfers comply with Rule
      144A, Regulation S or another applicable exemption under the Securities
      Act, as the case may be) and such other procedures as may from time to
      time be adopted by the Company.

            Restrictions on Transfer of Regulation S Global Securities. During
the Distribution Compliance Period, beneficial ownership interests in Regulation
S Global Securities may only be sold, pledged or transferred in accordance with
the Applicable Procedures and only (i) to the Company, (ii) in an offshore
transaction in accordance with Regulation S or (iii) pursuant to an effective
registration statement under the Securities Act, in each case in accordance with
any applicable securities laws of any State of the United States.

            Legend.

                  (i) Except as permitted by the following paragraphs (ii),
      (iii) and (iv), each Security certificate evidencing the Global Securities
      (and all Securities issued in exchange therefor or in substitution
      thereof), in the case of Securities offered otherwise than in reliance on
      Regulation S, shall bear a legend in substantially the following form:

            THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A
            TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES
            SECURITIES ACT OF 1933, as amended (THE "SECURITIES ACT"), AND THIS
            SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE
            ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM.
            EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER
            OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS
            OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER.

            THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY
            THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE
            TRANSFERRED, ONLY (I) TO THE COMPANY, (II) IN THE UNITED STATES TO A
            PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED
            INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES
            ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (III)
            OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE
            WITH RULE 904 UNDER THE SECURITIES ACT, (IV) TO AN institutional
            "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1), (2), (3) OR (7)
            OF REGULATION D UNDER THE SECURITIES ACT) THAT, PRIOR TO SUCH
            TRANSFER, FURNISHES TO THE TRUSTEE A SIGNED LETTER CONTAINING
            CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE TRANSFER OF
            THIS SECURITY (THE FORM OF WHICH CAN BE OBTAINED FROM THE TRUSTEE)
            AND, IF SUCH TRANSFER IS IN RESPECT OF AN AGGREGATE PRINCIPAL AMOUNT
            OF SECURITIES LESS THAN $250,000, AN OPINION OF COUNSEL ACCEPTABLE
            TO THE COMPANY THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE
            SECURITIES ACT, (V) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER
            THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR
            (VI) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
            SECURITIES ACT, IN EACH OF CASES (I) THROUGH (VI), IN ACCORDANCE
            WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED
            STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS
            REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF THE
            RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE.

                                   Page 101

<PAGE>

            Each certificate evidencing a Security offered in reliance on
      Regulation S shall bear a legend in substantially the following form:

            THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A
            TRANSACTION ORIGINALLY EXEMPT FROM REGISTRATION UNDER THE UNITED
            STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
            AND MAY NOT BE TRANSFERRED IN THE UNITED STATES OR TO, OR FOR THE
            ACCOUNT OR BENEFIT OF, ANY U.S. PERSON EXCEPT PURSUANT TO AN
            AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
            SECURITIES ACT AND ALL APPLICABLE STATE SECURITIES LAWS. TERMS USED
            ABOVE HAVE THE MEANINGS GIVEN TO THEM IN REGULATION S UNDER THE
            SECURITIES ACT.

            Each Definitive Security shall also bear the following additional
      legend:

            IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE
            REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION
            AS SUCH REGISTRAR AND TRANSFER AGENT MAY REASONABLY REQUIRE TO
            CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS.

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

                  (iii) After a transfer of any Initial Securities or Private
      Exchange Securities pursuant to and during the period of the effectiveness
      of a Shelf Registration Statement with respect to such Initial Securities
      or Private Exchange Securities, as the case may be, all requirements
      pertaining to legends on such Initial Security or such Private Exchange
      Security will cease to apply, the requirements requiring any such Initial
      Security or such Private Exchange Security issued to certain Holders be
      issued in global form will cease to apply, and a certificated Initial
      Security or Private Exchange Security or an Initial Security or Private
      Exchange Security in global form, in each case without restrictive
      transfer legends, will be available to the transferee of the Holder of
      such Initial Securities or Private Exchange Securities upon exchange of
      such transferring Holder's certificated Initial Security or Private
      Exchange Security or directions to transfer such Holder's interest in the
      Global Security, as applicable.

                  (iv) Upon the consummation of a Registered Exchange Offer with
      respect to the Initial Securities, all requirements pertaining to such
      Initial Securities that Initial Securities issued to certain Holders be
      issued in global form will still apply with respect to Holders of such
      Initial Securities that do not exchange their Initial Securities, and
      Exchange Securities in certificated or global form, in each case without
      the restricted securities legend set forth in Exhibit 1 hereto will be
      available to Holders that exchange such Initial Securities in such
      Registered Exchange Offer.

                  (v) Upon the consummation of a Private Exchange with respect
      to the Initial Securities, all requirements pertaining to such Initial
      Securities that Initial Securities issued to certain Holders be issued in
      global form will still apply with respect to Holders of such Initial
      Securities that do not exchange their Initial Securities, and Private

                                   Page 102

<PAGE>

      Exchange Securities in global form with the global securities legend and
      the applicable restricted securities legend set forth in Exhibit 1 hereto
      will be available to Holders that exchange such Initial Securities in such
      Private Exchange.

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

            No Obligation of the Trustee.

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

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

            2.4 Definitive Securities.

            (a) A Global Security deposited with the Depository or with the
Trustee as Securities Custodian for the Depository pursuant to Section 2.1 shall
be transferred to the beneficial owners thereof in the form of Definitive
Securities in an aggregate principal amount equal to the principal amount of
such Global Security, in exchange for such Global Security, only if such
transfer complies with Section 2.3 hereof and (i) the Depository notifies the
Company that it is unwilling or unable to continue as Depository for such Global
Security and the Depository fails to appoint a successor depository or if at any
time such Depository ceases to be a "clearing agency" registered under the
Exchange Act and, in either case, a successor depository is not appointed by the
Company within 90 days of such notice, or (ii) an Event of Default has occurred
and is continuing or (iii) the Company, in its sole discretion, notifies the
Trustee in writing that it elects to cause the issuance of Definitive Securities
under this Indenture.

            (b) Any Global Security that is transferable to the beneficial
owners thereof pursuant to this Section 2.4 shall be surrendered by the
Depository to the Trustee located at its principal corporate trust office in the
Borough of Manhattan, The City of New York, to be so transferred, in whole or
from time to time in part, without charge, and the Trustee shall authenticate
and deliver, upon such transfer of each portion of such Global Security, an
equal aggregate principal amount of Definitive Securities of authorized
denominations. Any portion of a Global Security transferred pursuant to this
Section 2.4 shall be executed, authenticated and delivered only in denominations
of $1,000 principal amount and any integral multiple thereof and registered in
such names as the Depository shall direct. Any Definitive Security delivered in
exchange for an interest in the Transfer Restricted Security shall, except as
otherwise provided by Section 2.3(e) hereof, bear the applicable restricted
securities legend and definitive securities legend set forth in Exhibit 1
hereto.

            (c) Subject to the provisions of Section 2.4(b) hereof, the
registered Holder of a Global Security shall be entitled to grant proxies and
otherwise authorize any Person, including Agent Members and Persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Securities.

            (d) In the event of the occurrence of one of the events specified in
Section 2.4(a) hereof, the Company shall promptly make available to the Trustee
a reasonable supply of Definitive Securities in definitive, fully registered
form without interest coupons. In the event that such Definitive Securities are
not issued, the Company expressly acknowledges, with respect to the right of any
Holder to pursue a remedy pursuant to Section 6.06 of the Indenture, the right
of any beneficial owner of Securities to pursue such remedy with respect to the
portion of the Global Security that represents such beneficial owner's
Securities as if such Definitive Securities had been issued.

                  [FORM OF REVERSE SIDE OF INITIAL SECURITY]

                9% First Preferred Ship Mortgage Note Due 2014

      1.    Interest

            Ultrapetrol (Bahamas) Limited, a Bahamian corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal amount of this Security at the rate per annum shown above; provided,
however, that if a Registration Default (as defined in the Registration Rights
Agreement) occurs, interest will accrue on this Security at a rate of 10% per
annum from and including the date on which any such Registration Default shall
occur to but excluding the date on which all Registration Defaults have been
cured. The Company will pay interest semiannually on May 24 and November 24 of
each year, commencing May 24, 2005. Interest on the Securities will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from November 24, 2004. Interest will be computed on the basis of a
360-day year of twelve 30-day months. The Company shall pay interest on overdue
principal at the rate borne by the Securities plus 1% per annum, and it shall
pay interest on overdue installments of interest at the same rate to the extent
lawful.

      2.    Method of Payment

            The Company will pay interest on the Securities (except defaulted
interest) to the Persons who are registered holders of Securities at the close
of business on the May 9 or November 9 next preceding the interest payment date

                                   Page 106

<PAGE>

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

      3.    Paying Agent and Registrar

            Initially, Manufacturers and Traders Trust Company, a New York
banking corporation ("Trustee"), will act as Paying Agent and Registrar. The
Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice. The Company or any of its domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar.

      4.    Indenture

            The Company issued the Securities under an Indenture dated as of
November 24, 2004 ("Indenture"), among the Company, the Subsidiary Guarantors,
the Pledgors and the Trustee. The terms of the Securities include those stated
in the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as in effect on the date
of the Indenture (the "Act"). Terms defined in the Indenture and not defined
herein have the meanings ascribed thereto in the Indenture. The Securities are
subject to all such terms, and Securityholders are referred to the Indenture and
the Act for a statement of those terms.

            The Securities are general secured obligations of the Company
limited to $180,000,000 aggregate principal amount (subject to Section 2.06 of
the Indenture). The Initial Securities issued on the Issue Date and all Exchange
Securities or Private Exchange Securities issued in exchange therefor will be
treated as a single class for all purposes under the Indenture. The Indenture
contains covenants that limit (i) the incurrence of additional debt by the
Company and its subsidiaries, (ii) the payment of dividends on capital stock of
the Company and the purchase, redemption or retirement of capital stock or
subordinated indebtedness, (iii) investments, (iv) certain liens and
Sale/Leaseback transactions, (v) certain transactions with affiliates, (vi)
sales of assets, (vii) lines of business and (viii) certain consolidations,
mergers and transfers of assets. The Indenture also prohibits certain
restrictions on distributions from subsidiaries. These covenants are subject to
important exceptions and qualifications.

      5.    Optional Redemption

            Except as set forth in the next three paragraphs and in paragraph 6
below, the Securities may not be redeemed prior to November 24, 2009. On and
after that date, the Company may redeem the Securities in whole at any time or
in part from time to time upon not less than 30 nor more than 60 days' notice at
the following redemption prices (expressed in percentages of principal amount on
the redemption date), plus accrued interest to the redemption date (subject to
the right of Holders of record on the relevant record date to receive interest
due on the related interest payment date):

                                   Page 107

            In addition, at any time and from time to time prior to November 24,
2007, the Company shall be entitled at its option on one or more occasions to
redeem Securities in an aggregate principal amount not to exceed 35% of the
aggregate principal amount of Securities with the proceeds of one or more Public
Equity Offerings following which there is a Public Market, at a redemption price
(expressed as a percentage of principal amount) of 109.00% plus accrued interest
to the redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the related interest payment
date); provided, however, that at least $115.0 million aggregate principal
amount of the Securities must remain outstanding and be held, directly or
indirectly, by Persons other than the Company and its Affiliates, after each
such redemption.

            Prior to November 24, 2009, the Company shall be entitled at its
option to redeem all, but not less than all, of the Securities at a redemption
price equal to 100% of the principal amount of the Securities plus the
Applicable Premium as of, and accrued and unpaid interest to, the redemption
date (subject to the right of Holders on the relevant record date to receive
interest due on the relevant interest payment date).

            In addition, Securities may be redeemed, at the option of the
Company, at any time as a whole but not in part, on not less than 30 nor more
than 60 days' notice, at 100% of the principal amount thereof, plus accrued and
unpaid interest to the date of redemption (subject to the right of holders of
record on the relevant record date to receive interest due on the relevant
interest payment date), in the event the Company or the Subsidiary Guarantors or
the Pledgors, as the case may be, has become or would become obligated to pay,
on the next date on which any amount would be payable with respect to the
Securities, any Additional Amounts as a result of a change in or an amendment to
the laws (including any regulations or rulings promulgated thereunder) of the
Bahamas, Argentina, Bolivia, Liberia, Paraguay, Argentina, Panama, Uruguay or
Chile (or any relevant jurisdiction, political subdivision or taxing authority
thereof or therein), or any change in or amendment to any official position
regarding the application or interpretation of such laws, regulations or rulings
(including a holding by a court of competent jurisdiction), which change or
amendment is announced or becomes effective on or after the Issue Date and the
Company, the Subsidiary Guarantors or the Pledgors, as the case may be, cannot
avoid such obligations by taking reasonable steps to avoid them; provided,
however, that (a) no such notice of redemption shall be given earlier than 60
days prior to the earliest date on which the Company, the Subsidiary Guarantors
or the Pledgors, as the case may be, would be obligated to pay such Additional
Amounts if a payment in respect of the Securities or the Subsidiary Guarantee
were then due, and (b) at the time any such redemption notice is given, such
obligation to pay Additional Amounts must remain in effect. Prior to any such
redemption of the Securities, the Company shall deliver to the Trustee or any
paying agent an Officers' Certificate stating that the Company is entitled to
effect such redemption and setting forth a statement of facts showing that the
conditions precedent to the right of redemption have occurred.

      6.    Other Redemptions

            To the extent that, after the close of business on December 31,

                                   Page 108

<PAGE>

2005, the amount of cash and the fair market value (as determined by the Board
of Directors in good faith) of securities on deposit in the Escrow Account
exceeds $1.0 million, the Company will be obligated to use all such remaining
Escrowed Property to redeem (the "Special Mandatory Redemption") as much
principal amount of the Securities as can be redeemed with such Escrowed
Property at a redemption price equal to the sum of 101% of the principal amount
of such Securities, and the accrued interest thereon to the Special Mandatory
Redemption Date (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date) (such
redemption price, the "Special Mandatory Redemption Price"). For purposes
hereof, "Special Mandatory Redemption Date" means January 30, 2006.

            Upon the permitted sale of a Mortgaged Vessel or the Capital Stock
of a Subsidiary Guarantor (other than the sale by a Pledgor of its Mortgaged
Vessel or the sale of its Capital Stock to the Company or a Restricted
Subsidiary) (which term shall not include the transfer of the operation of a
Mortgaged Vessel pursuant to a bareboat charter with a purchase option) or an
Event of Loss with respect to a Mortgaged Vessel, the Company must either (a)
not later than 60 days after the Proceeds Receipt Date, redeem Securities, in
whole or in part on a pro rata basis, in an aggregate principal amount equal to
(i) the Redemption Amount or (ii) the Net Available Cash or Net Event of Loss
Proceeds, as the case may be, at a redemption price equal to the Sale Redemption
Price or the Loss Redemption Price, as the case may be (provided, however, that
if a Default shall have occurred and be continuing on the Notification Date, the
amount required to be applied by the Company to redeem Securities shall equal
the greater of such Redemption Amount and such Net Available Cash or Net Event
of Loss Proceeds, as the case may be), or (b) if no Default shall have occurred
and be continuing, tender to the Trustee a Qualified Substitute Vessel within 12
months after the Proceeds Receipt Date.

            In the event that the Company, a Subsidiary Guarantor or a Pledgor
enters into a Bareboat Charter, the Company must either (a) not later than 60
days after the date title to the relevant Mortgaged Vessel passes to the
charterer, redeem Securities, in whole or in part on a pro rata basis, in such
principal amount as can be redeemed with the Sale Equivalent Portion of the
Bareboat Charter Funds at the Sale Redemption Price or (b) if no Default shall
have occurred and be continuing, tender to the Trustee as part of the Collateral
one or more Vessels within 12 months of the date title to such Mortgaged Vessel
passes to the charterer.

      7.    Notice of Redemption

            Notice of redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to each Holder of Securities to be
redeemed at his registered address. Securities in denominations larger than
$1,000 may be redeemed in part but only in whole multiples of $1,000. If money
sufficient to pay the redemption price of and accrued interest on all Securities
(or portions thereof) to be redeemed on the redemption date is deposited with
the Paying Agent on or before the redemption date, on and after such date
interest ceases to accrue on such Securities (or such portions thereof) called
for redemption.

      8.    Put Provisions

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

      9.    Guarantee

                                   Page 109

<PAGE>

            The payment by the Company of the principal of, and premium and
interest on, the Securities is fully and unconditionally guaranteed on a joint
and several senior basis by each of the Subsidiary Guarantors to the extent set
forth in the Indenture.

      10.   Security

            The Securities will be secured by the Mortgages on the Mortgaged
Vessels, the security interests created by the other Security Agreements, the
Escrowed Property and all the issued and outstanding Capital Stock of certain of
the Subsidiary Guarantors.

      11.   Denominations; Transfer; Exchange

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

      12.   Persons Deemed Owners

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

      13.   Unclaimed Money

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

      14.   Discharge and Defeasance

            Subject to certain conditions, the Company at any time may terminate
some or all of its and the Subsidiary Guarantors' obligations under the
Securities, the Security Agreements and the Indenture if the Company deposits
with the Trustee money or U.S. Government Obligations for the payment of
principal and interest on the Securities to redemption or maturity, as the case
may be.

      15.   Amendment, Waiver

            Subject to certain exceptions set forth in the Indenture, (i) the
Indenture, the Security Agreements or the Securities may be amended with the
written consent of the Holders of at least a majority in principal amount
outstanding of the Securities and (ii) any default or noncompliance with any
provision may be waived with the written consent of the Holders of a majority in
principal amount outstanding of the Securities. Subject to certain exceptions
set forth in the Indenture, without the consent of any Securityholder, the
Company, the Subsidiary Guarantors, the Pledgors and the Trustee may amend the
Indenture, the Security Agreements or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 5 of the Indenture,
or to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add additional guarantees with respect to the
Securities or to provide additional security for the Securities, or to add

                                   Page 110

additional covenants or surrender rights and powers conferred on the Company or
a Subsidiary Guarantor or a Pledgor, or to comply with any request of the SEC in
connection with qualifying the Indenture under the Act, or to make any change
that does not adversely affect the rights of any Securityholder.

      16.   Defaults and Remedies

            Under the Indenture, Events of Default include (i) default for 30
days in payment of interest on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon redemption pursuant to paragraph 5
or 6 of the Securities, upon required purchase, upon acceleration or otherwise,
or failure by the Company or the Subsidiary Guarantors to redeem or purchase
Securities when required; (iii) failure by the Company to comply with other
agreements in the Indenture or the Securities, in certain cases subject to
notice and lapse of time; (iv) certain accelerations (including failure to pay
within any grace period after final maturity) of other Indebtedness of the
Company or Significant Subsidiaries if the amount accelerated (or so unpaid)
exceeds $5.0 million; (v) certain events of bankruptcy or insolvency with
respect to the Company or Significant Subsidiaries; (vi) certain judgments or
decrees for the payment of money in excess of $5.0 million and (vii) certain
events or defaults with respect to the Subsidiary Guarantees or the Security
Agreements. If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Securities may declare all
the Securities to be due and payable immediately. Certain events of bankruptcy
or insolvency are Events of Default which will result in the Securities being
due and payable immediately upon the occurrence of such Events of Default.

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

      17.   Trustee Dealings with the Company

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

      18.   No Recourse Against Others

            A director, officer, employee or stockholder, as such, of the
Company or the Trustee shall not have any liability for any obligations of the
Company under the Securities or the Indenture or for any claim based on, in
respect of or by reason of such obligations or their creation. By accepting a
Security, each Securityholder waives and releases all such liability. The waiver
and release are part of the consideration for the issue of the Securities.

      19.   Authentication

            This Security shall not be valid until an authorized signatory of
the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

      20.   Abbreviations

            Customary abbreviations may be used in the name of a Securityholder
or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

      21.   CUSIP Numbers

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

      22.   Holders' Compliance with Registration Rights Agreement

            Each Holder of a Security, by acceptance hereof, acknowledges and
agrees to the provisions of the Registration Rights Agreement, including the
obligations of the Holders with respect to a registration and the
indemnification of the Company and the Subsidiary Guarantors to the extent
provided therein.

      23.   Governing Law

            THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF NEW YORK.

                       [OR PRIVATE EXCHANGE SECURITY]]

                9% First Preferred Ship Mortgage Note Due 2004

      1.    Interest

            Ultrapetrol (Bahamas) Limited, a Bahamian corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal amount of this Security at the rate per annum shown above; provided,
however, that if a Registration Default (as defined in the Registration Rights
Agreement) occurs, interest will accrue on this Security at a rate of 10% per
annum from and including the date on which any such Registration Default shall
occur to but excluding the date on which all Registration Defaults have been
cured. The Company will pay interest semiannually on May 24 and November 24 of
each year, commencing May 24, 2005. Interest on the Securities will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from November 24, 2004. Interest will be computed on the basis of a
360-day year of twelve 30-day months. The Company shall pay interest on overdue
principal at the rate borne by the Securities plus 1% per annum, and it shall
pay interest on overdue installments of interest at the same rate to the extent
lawful.

      2.    Method of Payment

            The Company will pay interest on the Securities (except defaulted
interest) to the Persons who are registered holders of Securities at the close
of business on the May 9 or November 9 next preceding the interest payment date
even if Securities are canceled after the record date and on or before the
interest payment date. Holders must surrender Securities to a Paying Agent to
collect principal payments. The Company will pay principal and interest in money
of the United States that at the time of payment is legal tender for payment of
public and private debts. Payments in respect of the Securities represented by a
Global Security (including principal, premium and interest) will be made by wire
transfer of immediately available funds to the accounts specified by the
Depository. The Company will make all payments in respect of a certificated
Security (including principal, premium and interest) by mailing a check to the
registered address of each Holder thereof; provided, however, that payments on a
certificated Security will be made by wire transfer to a U.S. dollar account
maintained by the payee with a bank in the United States if such Holder elects
payment by wire transfer by giving written notice to the Trustee or the Paying
Agent to such effect designating such account no later than 30 days immediately
preceding the relevant due date for payment (or such other date as the Trustee
may accept in its discretion).

      3.    Paying Agent and Registrar

            Initially, Manufacturers and Traders Trust Company, a New York
banking corporation ("Trustee"), will act as Paying Agent and Registrar. The
Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice. The Company or any of its domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar.

      4.    Indenture

            The Company issued the Securities under an Indenture dated as of
November 24, 2004 ("Indenture"), among the Company, the Subsidiary Guarantors,
the Pledgors and the Trustee. The terms of the Securities include those stated
in the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as in effect on the date
of the Indenture (the "Act"). Terms defined in the Indenture and not defined
herein have the meanings ascribed thereto in the Indenture. The Securities are
subject to all such terms, and Securityholders are referred to the Indenture and
the Act for a statement of those terms.

            The Securities are general secured obligations of the Company
limited to $180,000,000 aggregate principal amount (subject to Section 2.06 of
the Indenture). The Initial Securities issued on the Issue Date and all Exchange

                                   Page 118

<PAGE>

Securities or Private Exchange Securities issued in exchange therefor will be
treated as a single class for all purposes under the Indenture. The Indenture
contains covenants that limit (i) the incurrence of additional debt by the
Company and its subsidiaries, (ii) the payment of dividends on capital stock of
the Company and the purchase, redemption or retirement of capital stock or
subordinated indebtedness, (iii) investments, (iv) certain liens and
Sale/Leaseback transactions, (v) certain transactions with affiliates, (vi)
sales of assets, (vii) lines of business and (viii) certain consolidations,
mergers and transfers of assets. The Indenture also prohibits certain
restrictions on distributions from subsidiaries. These covenants are subject to
important exceptions and qualifications.

      5.    Optional Redemption

            Except as set forth in the next three paragraphs and in paragraph 6
below, the Securities may not be redeemed prior to November 24, 2009. On and
after that date, the Company may redeem the Securities in whole at any time or
in part from time to time upon not less than 30 nor more than 60 days' notice at
the following redemption prices (expressed in percentages of principal amount on
the redemption date), plus accrued interest to the redemption date (subject to
the right of Holders of record on the relevant record date to receive interest
due on the related interest payment date):

if redeemed during the 12-month period beginning November 24, of the year set
forth below

<TABLE>

2012 and thereafter........................................      100.000
</TABLE>

            In addition, at any time and from time to time prior to November 24,
2007, the Company shall be entitled at its option on one of more occasions to
redeem Securities in an aggregate principal amount not to exceed 35% of the
aggregate principal amount of Securities with the proceeds of one or more Public
Equity Offerings following which there is a Public Market, at a redemption price
(expressed as a percentage of principal amount) of 109.00% plus accrued interest
to the redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the related interest payment
date); provided, however, that at least $115.0 million aggregate principal
amount of the Securities must remain outstanding and be held, directly or
indirectly, by Persons other than the Company and its Affiliates, after each
such redemption.

            Prior to November 24, 2009, the Company shall be entitled at its
option to redeem all, but not less than all, of the Securities at a redemption
price equal to 100% of the principal amount of the Securities plus the
Applicable Premium as of, and accrued and unpaid interest to, the redemption
date (subject to the right of Holders on the relevant record date to receive
interest due on the relevant interest payment date).

            In addition, Securities may be redeemed, at the option of the
Company, at any time as a whole but not in part, on not less than 30 nor more
than 60 days' notice, at 100% of the principal amount thereof, plus accrued and
unpaid interest to the date of redemption (subject to the right of holders of
record on the relevant record date to receive interest due on the relevant
interest payment date), in the event the Company or the Subsidiary Guarantors or
the Pledgors, as the case may be, has become or would become obligated to pay,
on the next date on which any amount would be payable with respect to the
Securities, any Additional Amounts as a result of a change in or an amendment to

                                   Page 119

<PAGE>

the laws (including any regulations or rulings promulgated thereunder) of the
Bahamas, Argentina, Bolivia, Liberia, Paraguay, Argentina, Panama, Uruguay or
Chile (or any relevant jurisdiction, political subdivision or taxing authority
thereof or therein), or any change in or amendment to any official position
regarding the application or interpretation of such laws, regulations or rulings
(including a holding by a court of competent jurisdiction), which change or
amendment is announced or becomes effective on or after the Issue Date and the
Company, the Subsidiary Guarantors or the Pledgors, as the case may be, cannot
avoid such obligations by taking reasonable steps to avoid them; provided,
however, that (a) no such notice of redemption shall be given earlier than 60
days prior to the earliest date on which the Company, the Subsidiary Guarantors
or the Pledgors, as the case may be, would be obligated to pay such Additional
Amounts if a payment in respect of the Securities or the Subsidiary Guarantee
were then due, and (b) at the time any such redemption notice is given, such
obligation to pay Additional Amounts must remain in effect. Prior to any such
redemption of the Securities, the Company shall deliver to the Trustee or any
paying agent an Officers' Certificate stating that the Company is entitled to
effect such redemption and setting forth a statement of facts showing that the
conditions precedent to the right of redemption have occurred.

      6.    Other Redemptions

            To the extent that, after the close of business on December 31,
2005, the amount of cash and the fair market value (as determined by the Board
of Directors in good faith) of securities on deposit in the Escrow Account
exceeds $1.0 million, the Company will be obligated to use all such remaining
Escrowed Property to redeem (the "Special Mandatory Redemption") as much
principal amount of the Securities as can be redeemed with such Escrowed
Property at a redemption price equal to the sum of 101% of the principal amount
of such Securities, and the accrued interest thereon to the Special Mandatory
Redemption Date (subject to the right of Holders of record on the relevant

(i) the Redemption Amount or (ii) the Net Available Cash or Net Event of Loss
Proceeds, as the case may be, at a redemption price equal to the Sale Redemption
Price or the Loss Redemption Price, as the case may be (provided, however, that
if a Default shall have occurred and be continuing on the Notification Date, the
amount required to be applied by the Company to redeem Securities shall equal
the greater of such Redemption Amount and such Net Available Cash or Net Event
of Loss Proceeds, as the case may be), or (b) if no Default shall have occurred
and be continuing, tender to the Trustee a Qualified Substitute Vessel within 12
months after the Proceeds Receipt Date.

            In the event that the Company, a Subsidiary Guarantor or a Pledgor
enters into a Bareboat Charter, the Company must either (a) not later than 60

charterer, redeem Securities, in whole or in part on a pro rata basis, in such
principal amount as can be redeemed with the Sale Equivalent Portion of the

right to cause the Company to repurchase all or any part of the Securities of
such Holder at a repurchase price equal to 101% of the principal amount of the
Securities to be repurchased plus accrued interest to the date of repurchase
(subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date) as provided in, and
subject to the terms of, the Indenture.

      9.    Guarantee

            The payment by the Company of the principal of, and premium and
interest on, the Securities is fully and unconditionally guaranteed on a joint
and several senior basis by each of the Subsidiary Guarantors to the extent set
forth in the Indenture.

      10.   Security

            The Securities will be secured by the Mortgages on the Mortgaged

the Subsidiary Guarantors.

      11.   Denominations; Transfer; Exchange

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

Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

      14.   Discharge and Defeasance

                                   Page 121

<PAGE>

            Subject to certain conditions, the Company at any time may terminate
some or all of its and the Subsidiary Guarantors' obligations under the
Securities, the Security Agreements and the Indenture if the Company deposits
with the Trustee money or U.S. Government Obligations for the payment of
principal and interest on the Securities to redemption or maturity, as the case
may be.

      15.   Amendment, Waiver

            Subject to certain exceptions set forth in the Indenture, (i) the
Indenture, the Security Agreements, or the Securities may be amended with the
written consent of the Holders of at least a majority in principal amount
outstanding of the Securities and (ii) any default or noncompliance with any
provision may be waived with the written consent of the Holders of a majority in
principal amount outstanding of the Securities. Subject to certain exceptions
set forth in the Indenture, without the consent of any Securityholder, the
Company, the Subsidiary Guarantors, the Pledgors and the Trustee may amend the
Indenture, the Security Agreements or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 5 of the Indenture,
or to provide for uncertificated Securities in addition to or in place of
certificated Securities, or to add additional guarantees with respect to the
Securities or to provide additional security for the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company or
a Subsidiary Guarantor or a Pledgor, or to comply with any request of the SEC in
connection with qualifying the Indenture under the Act, or to make any change
that does not adversely affect the rights of any Securityholder.

      16.   Defaults and Remedies

            Under the Indenture, Events of Default include (i) default for 30
days in payment of interest on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon redemption pursuant to paragraph 5
or 6 of the Securities, upon required purchase, upon acceleration or otherwise,
or failure by the Company or the Subsidiary Guarantors to redeem or purchase
Securities when required; (iii) failure by the Company to comply with other
agreements in the Indenture or the Securities, in certain cases subject to
notice and lapse of time; (iv) certain accelerations (including failure to pay
within any grace period after final maturity) of other Indebtedness of the
Company or Significant Subsidiaries if the amount accelerated (or so unpaid)
exceeds $5.0 million; (v) certain events of bankruptcy or insolvency with
respect to the Company or Significant Subsidiaries; (vi) certain judgments or
decrees for the payment of money in excess of $5.0 million and (vii) certain
events or defaults with respect to the Subsidiary Guarantees or the Security
Agreements. If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Securities may declare all
the Securities to be due and payable immediately. Certain events of bankruptcy
or insolvency are Events of Default which will result in the Securities being
due and payable immediately upon the occurrence of such Events of Default.

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

      17.   Trustee Dealings with the Company

            Subject to certain limitations imposed by the Act, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or

<PAGE>

pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

      18.   No Recourse Against Others

            A director, officer, employee or stockholder, as such, of the
Company or the Trustee shall not have any liability for any obligations of the
Company under the Securities or the Indenture or for any claim based on, in
respect of or by reason of such obligations or their creation. By accepting a
Security, each Securityholder waives and releases all such liability. The waiver
and release are part of the consideration for the issue of the Securities.

      19.   Authentication

            This Security shall not be valid until an authorized signatory of
the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

      21.   CUSIP Numbers

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

            Each Holder of a Security, by acceptance hereof, acknowledges and
agrees to the provisions of the Registration Rights Agreement, including the

                    and discharge all such debts, damages and liabilities as are
                    therein mentioned and/or to take any such measures as it
                    deems expedient or necessary for the purpose of securing the
                    release of the relevant Vessel;

and each and every expense or liability so incurred by the Trustee shall be
recoverable from the Owner as hereinbefore provided.

          5. Events of Default. Upon happening of any of the following events
(an "Event of Default") the Trustee may declare immediately due and payable all
the Obligations (in which case all of the same shall be immediately due), and
bring suit at law, in equity or in admiralty, as it may be advised, to recover
judgment for the Obligations and collect the same out of any and all property of
the Owner whether covered by this Mortgage or otherwise.

          The events referred to above are any and/or all of the following:

          (a)  an Event of Default under the Indenture;

          (b)  a default in the payment of the Obligations, when due at maturity
               (together with any applicable grace period) or by acceleration;

          (c)  a default by the Owner in the due and punctual observance of any
               of the covenants contained in subclauses (A), (B), (C), (D), (E),
               (F), (G), (K), (L), (M), (N), (P), (Q), (R), (S), and (U) of
               Clause 3 of this Mortgage;

          (d)  a default by the Owner in the due and punctual observance of any
               of the covenants contained in subclauses (H), (I), (J), (O) and
               (T) of Clause 3 of this Mortgage which default continues
               unremedied for a period of thirty (30) days after notice thereof
               from the Trustee to the Owner;

          (e)  it becomes impossible or unlawful for the Owner to fulfill any of
               the covenants and obligations contained in this Mortgage and the
               Trustee considers that such impossibility or illegality will have
               a material adverse effect on its rights under this Mortgage or
               the enforcement thereof;

          6. Remedies. Subject to Clause 11 below, if an Event of Default
specified in Clause 5 hereof occurs, the Trustee shall become forthwith entitled
to put into force and to exercise all rights and remedies in foreclosure and
otherwise given to mortgagees by the provisions of applicable law and all the
powers possessed by it as mortgagee of [the/each] Vessel and in particular:

                                   Page 137

<PAGE>

          (A)  To take and enter into possession of the Vessel[s, or any of
               them], at any time, wherever the same may be, without legal
               process and without being responsible for loss or damage, and the
               Owner or other person in possession forthwith upon demand of the
               Trustee will surrender to the Trustee possession of the Vessel[s,
               or any of them], and the Trustee may, without being responsible
               for loss or damage, hold, lay-up, lease, charter, operate or
               otherwise use the Vessel[s, or any of them,] 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 in general average, and all other sums due or to
               become due in respect of the Vessel[s, or any of them], or in
               respect of any insurance thereon from any person whomsoever, in
               accordance with the terms of this Mortgage.

          (B)  To take and enter into possession of the Vessel[s, or any of
               them], at any time, wherever the same may be, without legal
               process, and if it seems desirable to the Trustee and without
               being responsible for loss or damage, sell the Vessel[s, or any
               of them,] at any place and at such time as the Trustee may
               specify and in any such manner and such place (whether by public
               or private sale) as the Trustee may deem advisable, in accordance
               with the terms of this Mortgage and with power to postpone any
               such sale and without being answerable for any loss occasioned by
               such sale or resulting from postponement thereof.

          (C)  To discharge, compound, release or compromise claims against the
               Owner in respect of the Vessel[s, or any of them,] which have
               given or may give rise to any charge or lien on the Vessel[s, or
               any of them], or which are or may be enforceable by proceedings
               against the Vessel[s, or any of them].

          (D)  Pending sale of the Vessel[s, or any of them], to manage, insure,
               maintain and repair the Vessel[s, or any of them], and to employ,
               sail or lay up the Vessel[s, or any of them,] in such manner and
               for such period as the Trustee in its absolute discretion shall
               deem expedient and for the purposes aforesaid the Trustee shall
               be entitled to do all acts and things incidental or conducive
               thereto and in particular to enter into such arrangements
               respecting the Vessel[s, or any of them,] its respective
               insurance, management, maintenance, repair, classification and
               employment including (without limitation) giving all necessary
               instructions to the Master concerning use and operation of the
               Vessel[s, or any of them,] in all respects as if the Trustee were
               the owner of the Vessel[s] and without being responsible for any
               loss thereby incurred.

          (E)  To recover from the Owner on demand any such losses as may be
               incurred by the Trustee in or about the exercise of the power
               vested in the Trustee under sub-clause (D) above.

          (F)  To recover from the Owner on demand all expenses, payments and
               disbursements incurred by the Trustee in or about or incidental
               to the exercise by it of any of the powers aforesaid.

          (G)  To exercise all the rights and remedies in foreclosure and
               otherwise given to mortgagees by the provisions of any applicable
               law.

          PROVIDED ALWAYS that

                                   Page 138

<PAGE>

          (a)  upon any sale of the Vessel[s, or any of them], or by the Trustee
               pursuant to sub-clause (B) above the purchaser shall not be bound
               to see or inquire whether the Trustee's power of sale has arisen
               in the manner herein provided, and the sale shall be deemed to be
               within the power of the Trustee, and the receipt of the Trustee
               for the purchase money shall effectively discharge the purchaser
               who shall not be or be in any way answerable therefor;

          (b)  any sale of the Vessel[s, or any of them,] made in pursuance of
               the Trustee's right under this Mortgage will operate to divest
               all right, title and interest of any nature whatsoever of the
               Owner therein and thereto and shall bar any claim from the Owner,
               its successors and assigns, and all persons claiming by, through
               or under them.

          7. Right of Sale. The Trustee is hereby appointed attorney-in-fact of
the Owner to execute and deliver to any buyer aforesaid, and is hereby vested
with full power and authority to make, in the name and on behalf of the Owner, a
good conveyance of the title to the Vessel[s] so sold, provided, however, that
the Trustee shall not exercise any of its powers under this Clause 7 unless an
Event of Default specified in Clause 5 hereof shall have occurred. In the event
of a sale of the Vessel[s, or any of them], under any power herein contained,
the Owner will, if and when required by the Trustee, execute such form of
conveyance of the Vessel[s, or any of them,] as the Trustee may direct or
approve.

          8. Receiver. Whenever any right to enter and take possession of the
Vessel[s, or any of them,] accrues to the Trustee, the Trustee may require the
Owner to deliver or to cause to be delivered, and the Owner shall on demand, at
its own cost and expense, deliver or cause to be delivered to the Trustee the
Vessel[s, or any of them], as demanded. If any legal proceedings shall be taken
to enforce such right under this Mortgage, the Trustee shall be entitled as a
matter of right to the appointment of a receiver of the Vessel[s, or any of
them], and the freights, hire, earnings, revenues, income and profits due or to
become due and arising from the operation thereof.

          9. Right to Defend. Upon the happening of any Event of Default
specified in Clause 5 hereof, the Owner authorizes and empowers the Trustee or
its appointee to appear in the name of the Owner, its successors and assigns, in
any court of any country or nation of the world where a suit is pending against
the Vessel[s, or any of them,] because of or on account of any alleged lien
against the Vessel[s, or any of them,] from which the Vessel[s, or any of them,]
has not been released and to take such proceedings as may seem proper towards
the defense of such suit and the purchase or discharge of such lien, and all
expenditures made or incurred by it for the purpose of such defense, purchase,
or discharge shall be a debt due from the Owner, its successors, and assigns to
the Trustee, and shall be secured by the lien of this Mortgage and the rights of
the Trustee hereunder.

          10. Remedies Cumulative. Each and every power and remedy herein given
to the Trustee shall be cumulative and shall be in addition to every other power
and remedy herein given or now or hereafter existing at law, in equity,
admiralty, or by statute, and each and every power and remedy whether herein
given or otherwise existing may be exercised from time to time and as often and
in such order as may be deemed expedient by the Trustee, and the exercise or the
beginning of the exercise of any power or remedy shall not be construed to be a
waiver of the right to exercise at the same time or thereafter any other power
or remedy. No delay or omission by the Trustee or any of the Securityholders in
the exercise of any right or power or in pursuance of any remedy accruing upon
any Event of Default specified in Clause 5 hereof shall impair any such right,
power, or remedy or be construed to be a waiver of any such Event of Default or
to be any acquiescence therein; nor shall the acceptance by the Trustee of any
security or of any payment of or on account of any part of the Obligations

                                   Page 139

<PAGE>

falling due for payment after any such Event of Default or of any payment on
account of any past default be construed to be a waiver of any right to take
advantage of any future Event of Default or of any past Event of Default not
completely cured thereby.

          11. Acceptance of Cure. If at any time after an Event of Default
specified in Clause 5 hereof and prior to the actual sale of the Vessel[s, or
any of them,] by the Trustee or prior to the commencement of any foreclosure
proceedings, the Owner offers to cure completely all such Events of Default and
to pay to the Trustee all expenses and advances incurred or made by it
consequent on such Events of Default, then the Trustee may accept, but is not
obligated to accept except as required pursuant to the terms of the Indenture,
such offer and payment and restore the Owner to its former position, but such
action shall not affect any subsequent Event of Default or impair any rights of
the Trustee consequent thereto.

          12. Application of Proceeds. All monies received by the Trustee in
respect of:

          (i)  the sale of the Vessel[s, or any of them],

          (ii) Requisition Compensation, or

         (iii) the charter, use or other disposition the Vessel[s, or any of
               them].

shall be first applied to pay or make good all such payments, disbursements,
expenses, attorneys fees and losses whatsoever (together with interest thereon
as hereinbefore provided for in the Indenture) as may have been incurred by the
Trustee in or about or incidental to the exercise by the Trustee of the powers
specified or otherwise referred to in Clauses 6, 7, 8, 9 and 14 hereof or any of
them and the balance shall be applied in the manner prescribed in the Indenture.

PROVIDED ALWAYS that in the event that such balance is insufficient to pay in
full the whole of the Obligations the Trustee shall be entitled to collect the
shortfall from the Owner or any other person liable therefor.

          13. No Waiver; Illegality; Invalidity. (A) No delay or omission of the
Trustee or any of the Securitiesholders to exercise any right or power vested in
them under this Mortgage, the Indenture or the Security Agreements or any of
them shall impair such right or power or be construed as a waiver of or as
acquiescence in any default by the Owner and no express waiver given by the
Trustee or any of the Securityholders in relation to any default by the Owner,
or breach by the Owner of any of its obligations under this Mortgage shall
prejudice the rights of the Trustee under this Mortgage, the Indenture or the
Security Agreements arising from any subsequent default or breach (whether or
not such subsequent default or breach is of a nature different from the previous
default or breach) nor shall the giving by the Trustee of any consent to the
doing of any act which by the terms hereof requires the consent of the Trustee
prejudice the right of the Trustee to give or withhold as it may think fit its
consent to the doing of any other such similar act.

          (B) The Trustee shall not be obliged to make any inquiry as to the
nature or sufficiency of any payment received by it hereunder or following the
occurrence of an Event of Default specified in Clause 5 hereof to make any claim
or take any action to collect any monies hereby assigned or to enforce any
rights and benefits hereby assigned to the Trustee or to which the Trustee may
at any time be entitled hereunder.

          (C) In case any one or more the provisions contained in this Mortgage
should be invalid, illegal or unenforceable in any respect under any law, the
validity, legality and enforceability of the remaining provisions contained
herein shall not in any be affected or impaired thereby and shall remain in full

                                   Page 140

<PAGE>

force and effect.

          14. Delegation. The Trustee shall be entitled at any time and as often
as may be expedient to delegate all or any of the powers and discretions vested
in it by the Indenture, the Security Agreements or this Mortgage or any of them
(including the power vested in it by virtue of Clause 11 hereof) in such manner
upon such terms and to such persons as the Trustee in its absolute discretion
may think fit, provided, however, that the Trustee shall not exercise its rights
under this Clause 14 until an Event of Default specified in Clause 5 hereof
shall have occurred and be continuing.

          15. Indemnity. THE OWNER HEREBY AGREES AND UNDERTAKES to indemnify the
Trustee against all obligations and liabilities whatsoever and whensoever
arising which the Trustee may incur in good faith in respect of, in relation to,
or in connection with the Vessel[s, or any of them], or otherwise howsoever in
relation to or in connection with any of the matters dealt with in the
Indenture, this Mortgage or the Security Agreements.

          16. Mortgagee as Attorney-in-Fact. (A) The Owner hereby irrevocably
appoints the Trustee as its attorney-in-fact for the duration of the Security
Period to do in its name or in the name of the Owner all acts which the Owner,
or its successors or assigns could do in relation to [any of] the Vessel[s],
including without limitation, to demand, collect, receive, compromise, settle
and sue for (insofar as the Trustee lawfully may), all freights, hire, earnings,
issues, revenues, income, and profits of the Vessel[s], and all amounts due from
underwriters under the Insurances as payment of losses or as return premiums or
otherwise, salvage awards and recoveries, recoveries in general, average or
otherwise, and all other sums due or to become due to the Owner or in respect of
the Vessel[s], and to make, give and execute in the name of the Owner,
acquittances, receipts, releases, or other discharges for the same, whether
under seal or otherwise, to take possession of, sell or otherwise dispose of or
manage or employ, [any of] the Vessel[s], to execute and deliver charters and a
bill of sale with respect to [any of] the Vessel[s], and to endorse and accept
in the name of the Owner all checks, notes, drafts, warrants, agreements and all
other instruments in writing with respect to the foregoing. PROVIDED, HOWEVER,
that, unless the context otherwise permits under this Mortgage, such power shall
not be exercisable by or on behalf of the Trustee unless and until any Event of
Default stipulated in Clause 5 hereof shall have occurred and be continuing.

          (B) The exercise of the power granted in this Clause 16 by or on
behalf of the Trustee shall not require any person dealing with the Trustee to
conduct any inquiry as to whether any such Event of Default has occurred and is
continuing, nor shall such person be in any way affected by notice that any such
Event of Default has not occurred nor is continuing, and the exercise by the
Trustee of such power shall be conclusive evidence of its right to exercise the
same.

          17. Owner's Right of Possession and Use. Unless and until an Event of
Default specified in Clause 5 hereof has occurred and be continuing, the Owner
(i) shall be permitted and suffered to retain title, actual possession and use
of the Vessel[s], and (ii) shall have the right, from time to time, in its
discretion, and without application to the Trustee, to dispose of, free from the
lien hereof, any boilers, engine, machinery, masts, spars, sail, rigging, boats,
anchors, cables, chains, tackle, apparel, furniture, fittings, equipment or any
other appurtenances of the Vessel[s] that are no longer useful, necessary,
profitable or advantageous in the operation of the Vessel[s], subject to first
or simultaneously replacing the same by new boilers, engines, machinery, masts,
spars, sails, rigging, boats, anchors, cables, chains, tackle, apparel,
furniture, fittings, equipment or other appurtenances of substantially equal
value to the Owner which shall forthwith become subject to the lien of this
Mortgage as a first preferred [fleet] mortgage thereon.

          18. Further Assurances. THE OWNER HEREBY FURTHER UNDERTAKES at its own

                                   Page 141

<PAGE>

expense to execute, sign, perfect, do and (if required) register every such
further assurance, document, act or thing as in the reasonable opinion of the
Trustee may be necessary or desirable for the purpose of more effectually
mortgaging the Vessel[s] or perfecting the security constituted by the Indenture
and this Mortgage.

          19. Extent of Security. The Vessel[s] and their respective equipment
and appurtenances shall respond for the principal amount of the indebtedness
secured by this Mortgage, including interest, costs and other charges secured by
this Mortgage.

          20. Special Power of Attorney. The Owner and the Trustee each confer a
special power of attorney with right of substitution upon [LOCAL COUNSEL NAME],
lawyers of [JURISDICTION] empowering them to take all necessary steps to
permanently record this instrument of mortgage in the appropriate registry of
the [JURISDICTION] and from time to time details of the indebtedness secured
hereby.

          21. No Waiver of Preferred Status. Anything herein to the contrary
notwithstanding, it is intended that nothing herein shall waive the preferred
status of this Mortgage under the laws of the [JURISDICTION], the United States
Vessel Mortgage Act, 1920, as amended, inter alia, by Public Law 100-710 (46 USC
Section 30101 et seq.) or the corresponding provisions of the laws of any other
jurisdiction in which it is sought to be enforced and that, if any provision or
portion thereof herein shall be construed to waive the preferred status of this
Mortgage, then such provision to such extent shall be void and of no effect.

          22. Notices. All notices, requests and other communications to any
party hereunder shall be in writing (including prepaid overnight courier,
facsimile transmission or similar writing) and shall be given to such party at
its address or facsimile number set forth below or at such other address or
facsimile number as such party may hereafter specify for the purpose by notice
to each other party hereto. Each such notice, request or other communication
shall be effective (i) if given by facsimile, when such facsimile is transmitted
to the facsimile number specified in this Clause and telephonic confirmation of
receipt thereof is obtained or (ii) if given by mail, prepaid overnight courier
or any other means, when received at the address specified in this Clause or
when delivery at such address is refused.

Ladies and Gentlemen:

                                   Page 153

     Upon transfer, the Securities would be registered in the name of the new
beneficial owner as follows:

Name:_________________________________________

Address:______________________________________

Taxpayer ID Number:___________________________

     The undersigned represents and warrants to you that:

     1. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the
"Securities Act")), purchasing for our own account or for the account of such an
institutional "accredited investor", and we are acquiring the Securities not
with a view to, or for offer or sale in connection with, any distribution in
violation of the Securities Act. We are purchasing at least $250,000 principal
amount of the Securities or, if less, are furnishing herewith an opinion of
counsel as described in clause (iii) of paragraph 2 below. We have such
knowledge and experience in financial and business matters as to be capable of
evaluating the merits and risks of our investment in the Securities, and we
invest in or purchase securities similar to the Securities in the normal course
of our business. We, and any accounts for which we are acting, are each able to
bear the economic risk of our or its investment.

     2. We understand that the Securities have not been registered under the
Securities Act and, unless so registered, may not be sold except as permitted in
the following sentence. We agree on our own behalf and on behalf of any investor
account for which we are purchasing Securities to offer, sell or otherwise
transfer such Securities prior to the date that is two years after the later of
the date of original issue and the last date on which the Company or any
affiliate of the Company was the owner of such Securities (or any predecessor
thereto) (the "Resale Restriction Termination Date") only (i) to the Company,
(ii) in the United States to a person whom the seller reasonably believes is a
qualified institutional buyer in a transaction meeting the requirements of Rule
144A, (iii) to an institutional "accredited investor" within the meaning of Rule
501(a)(1), (2), (3) or (7) under the Securities Act that is an institutional
accredited investor purchasing for its own account or for the account of an
institutional accredited investor, in each case in a minimum principal amount of
the Securities of $250,000, or if such transfer is in respect of an aggregate
principal amount of Securities of less than $250,000, only if such institutional
accredited investor furnishes to the Trustee an opinion of counsel acceptable to
the Company that such transfer is in compliance with the Securities Act, (iv)
outside the United States in a transaction complying with the provisions of Rule
904 under the Securities Act, (v) pursuant to an exemption from registration
under the Securities Act provided by Rule 144 (if available) or (vi) pursuant to
an effective registration statement under the Securities Act, in each of cases
(i) through (vi) subject to any requirement of law that the disposition of our
property or the property of such investor account or accounts be at all times
within our or their control and in compliance with any applicable state
securities laws. The foregoing restrictions on resale will not apply subsequent
to the Resale Restriction Termination Date. If any resale or other transfer of
the Securities is proposed to be made pursuant to clause (iii) above prior to
the Resale Restriction Termination Date, the transferor shall deliver a letter
from the transferee substantially in the form of this letter to the Trustee,
which shall provide, among other things, that the transferee is an institutional
"accredited investor" within the meaning of Rule 501(a)(1), (2), (3) or (7)
under the Securities Act and that it is acquiring such Securities for investment
purposes and not for distribution in violation of the Securities Act. Each
purchaser acknowledges that the Company and the Trustee reserve the right prior
to the offer, sale or other transfer prior to the Resale Restriction Termination
Date of the Securities pursuant to clause (iii), (iv) or (v) above to require
the delivery of an opinion of counsel, certifications or other information
satisfactory to the Company and the Trustee.

of [the/any] Vessel and her respective earnings;

                  (C)   the Insurances in effect on the date hereof are now
valid and in full force and effect, and the Assignor will not do or omit or

assigned hereby may become void or voidable in whole or in part or the Assignee
or any other person claiming title through it may be prevented from receiving
the proceeds thereof;

                  (D)   if by reason of anything done or omitted or knowingly
suffered to be done or omitted the Insurances assigned hereby shall at any time
become voidable in whole or in part, the Assignor will forthwith at its own cost
take all such action as shall be necessary for keeping such Insurances in force
and in particular will pay all premiums as they become due; and

                  (E)   if by reason of anything done or omitted or knowingly
suffered to be done or omitted the Insurances assigned hereby or any of them
shall at any time become void in whole or in part, the Assignor shall, at its
expense, affect new insurances in compliance with the terms of the Mortgage over
the Vessel[s,or any of them,] in favor of the Assignee, and shall forthwith (if
required by the Assignee), execute an assignment of such new insurances in favor
of the Assignee, and will pay any sums payable by way of premiums under the new
insurances.

            5.    No Duty of Inquiry. The Assignee shall not be obliged to make
any inquiry as to the nature or sufficiency of any payment received by it
hereunder or to make any claim or take any other action to collect any moneys or
to enforce any rights and benefits hereby assigned to the Assignee or to which
the Assignee may at any time be entitled hereunder except such reasonable action
as may be requested by any underwriter, association or club. The Assignor shall
remain liable to perform all the obligations assumed by it in relation to the
property hereby assigned, and the Assignee shall be under no obligation of any
kind whatsoever in respect thereof or be under any liability whatsoever

represent that it has not assigned or pledged, and hereby covenants that it will
not assign or pledge so long as this Assignment shall remain in effect, any of
its right, title or interest in the whole or any part of the Insurances or other
moneys and claims hereby assigned, to anyone other than the Assignee, and it
will not take or omit to take any action, the taking or omission of which might
result in an

                                       3
<PAGE>

alteration or impairment of the rights hereby assigned or any of the rights
created in this Assignment; and the Assignor hereby irrevocably appoints and
constitutes the Assignee as the Assignor's true and lawful attorney-in-fact with
full power (in the name of the Assignor or otherwise) should an Event of Default
(as such term is defined in the Indenture) have occurred and be continuing to
ask, require, demand, receive, compound and give acquittance for any and all
moneys and claims for moneys assigned hereby, to endorse any checks or other
instruments or orders in connection therewith and to file any claims or take any
action or institute any proceedings which the Assignee may deem to be necessary
or advisable and otherwise to do any and all things which the Assignor itself
could do in relation to the property hereby assigned, including, but not limited
to, filing any and all Uniform Commercial Code financing statements or renewals
thereof in connection with this Assignment which the Assignee may deem to be
necessary or advisable in order to perfect or maintain the security interest
granted hereby. The powers and authorities granted to the Assignee have been
given for valuable consideration and are hereby declared irrevocable.

            7.    Further Assurances. The Assignor agrees that any time and from

documents as the Assignee may reasonably deem advisable in obtaining the full
benefits of this Assignment and of the rights and powers herein granted.

            8.    Remedies Cumulative and Not Exclusive; No Waiver. Each and
every right, power and remedy herein given to the Assignee shall be cumulative

now or hereafter existing at law, in equity or by statute, and each and every
right, power and remedy, whether herein given or otherwise existing, may be
exercised from time to time, in whole or in part, and as often and in such order
as may be deemed expedient by the Assignee, and the exercise or the beginning of
the exercise of any right, power or remedy shall not be construed to be a waiver
of the right to exercise at the same time or thereafter any other right, power
or remedy. No delay or omission by the Assignee in the exercise of any right or
power in the pursuance of any remedy accruing upon any breach or default of the
Indenture by the Assignor, the Company or any other Guarantor or Pledgor shall
impair any such right, power or remedy or be construed to be a waiver of any
such right, power or remedy or to be an acquiescence therein; nor shall the
acceptance by the Assignee of any security or of any payment of or on account of
any of the amounts due from the Assignor, the Company or any other Guarantor or
Pledgor under or in connection with the Indenture or any document delivered in
connection therewith and maturing after any breach or default or of any payment
on account of any past breach or default be construed to be a waiver of any
right to take advantage of any future breach or default or of any past breach or
default not completely cured thereby.

            9.    Invalidity. If any provision of this Assignment shall at any
time for any reason be declared invalid, void or otherwise inoperative by a
court of competent jurisdiction, such declaration or decision shall not affect
the validity of any other provision or provisions of this Assignment, or the
validity of this Assignment as a whole, which shall remain in full force and
effect. In the event that it should transpire that by reason of any law or
regulation, or by reason of a ruling of any court, or by any other reason
whatsoever, the assignment herein

                                       4

to furnish the Assignee with an alternative assignment or alternative security

be required in order to ensure and give effect to the full intent of this
Assignment.

            10.   Continuing Security. It is declared and agreed that the
security created by this Assignment shall be held by the Assignee as a
continuing security for the payment of all moneys which may at any time and from
time to time be or become payable by the Company, the [other] Subsidiary
Guarantors or the Assignor under the Indenture and that the security so created
shall not be satisfied by any intermediate payment or satisfaction of any part
of the amount hereby secured and that the security so created shall be in
addition to and shall not in any way be prejudiced or affected by any other
collateral or security now or hereafter held by the Assignee for all or any part
of the moneys hereby secured.

            11.   Waiver; Amendment. None of the terms and conditions of this
Assignment may be changed, waived, modified or varied in any manner whatsoever
unless in writing duly signed by the Assignee and the Assignor.

            12.   Termination. If the Assignor shall pay and discharge all of
its obligations under or in connection with the Indenture and the Securities or
is released therefrom in accordance with the terms thereof, all the right, title
and interest herein assigned shall revert to the Assignor, and this Assignment
shall terminate.

            13.   WAIVER OF JURY TRIAL. EACH OF THE ASSIGNOR, AND BY ITS
ACCEPTANCE HEREOF, THE ASSIGNEE, HEREBY WAIVES TRIAL BY JURY IN ANY ACTION,
