            Representations and Warranties of Seller. Seller hereby represents
and warrants as to the matters pertaining solely to itself and, to the best of
its Knowledge, as to UP Offshore, its Subsidiaries and to any other matter
below, to the Buyer that:

2.1   Power and Authority.
      -------------------

            Seller has the full right, power and authority to enter into this
Agreement and to transfer, convey and sell to Buyer at the Closing the LAIF UP

Liens and, upon consummation of the purchase contemplated hereby, Buyer will
acquire from Seller good, valid and marketable title to the LAIF UP Offshore
Shares, free and clear of all Liens.

2.2   Authorization and Enforceability.
      --------------------------------

            The execution, delivery and performance of this Agreement has been
duly authorized by all necessary action on the part of Seller, and constitutes a
legal, valid and binding obligation of Seller, enforceable against Seller in
accordance with its terms, except as such enforceability may be limited by: (i)
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting the enforcement of creditors' rights generally; and (ii) general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

2.3   No Conflicts.
      ------------

            Neither the execution, delivery and performance of this Agreement
nor the consummation of any of the transactions contemplated hereunder will:

          (a) conflict with or result in any violation of or constitute a breach
of any of the terms or provisions of, or result in the acceleration of any
obligation under, or constitute a default under any provision of, the articles
of incorporation or bylaws or other organizational documents of either Seller or
UP Offshore, or any mortgage, bond, indenture, agreement, franchise, license,
permit or other instrument or obligation to which either Seller or UP Offshore
is a party or subject or by which any of their respective assets or properties
may be bound except as contained in the agreements listed in Schedule 2.5;

          (b) result in the creation of any Lien upon any of the assets or
properties of either Seller or UP Offshore; or

          (c) violate any Legal Requirement against, affecting or binding upon,
The Seller or UP Offshore or upon any of their respective assets or properties.

2.4   No Consents.
      -----------

            All consents, approvals or authorizations of, or registrations,
filings or declarations with, any Governmental Authority or any other Person, if
any, required in connection with the execution, delivery or performance by
either Seller of this Agreement or the transactions provided for herein have
been or at the Closing will have been obtained by such Seller and will be in
full force and effect.

2.5   Company Organization and Capitalization.
      ---------------------------------------

          (a) UP Offshore is a corporation, duly organized, validly existing and
in good standing under the laws of the Commonwealth of the Bahamas and is duly
qualified to do business and is in good standing in each jurisdiction in which
such qualification is required by law, other than those jurisdictions as to
which the failure to be so qualified or in good standing could not, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect.
UP Offshore has the power and authority to own or hold under lease the
properties it purports to own or hold under lease, to transact the business it
transacts and proposes to transact. Other than the articles of incorporation and
the by-laws of UP Offshore and the Shareholders Agreement (the "Shareholders
Agreement") among the Buyer, the Seller and Comintra Enterprises Ltd. (which
shareholders agreement is being restated contemporaneously herewith to remove
the Seller as a party thereto) and agreements listed on Schedule 2.5, there are
no other agreements or documents to which UP Offshore or either Seller is a
party with respect to the governance or capitalization of UP Offshore,

          (b) The authorized capital stock of UP Offshore consists solely of
60,000,000 shares of common stock, par value $0.01 and 20,000,000 shares of
preferred stock. As of the date hereof and as of the Closing Date, there are and
shall be 45,000,000 shares of common stock issued and outstanding as well as
3,000,000 shares of Series A preferred stock with a par value of $0.01 per share
issued and outstanding in favor of International Finance Corporation and such
shares constitute all of the issued and outstanding shares of the capital stock
of UP Offshore. All such shares have been duly authorized, validly issued and
are fully paid and non-assessable. Upon consummation of the Closing, Seller will
sell to the Buyer sixty-six and sixty-seven one hundredths of one percent
(66.67%) of the issued and outstanding common stock of UP Offshore owned by the
Seller.

          (c) Other than the Warrant Agreement, dated June 4, 2003 (scheduled
under Schedule 2.15), to the Seller's Knowledge, there are no outstanding
obligations, warrants, options or other rights to subscribe for or purchase from
UP Offshore, or other contracts or commitments providing for the issuance of or
the granting of rights to acquire, any equity interest in UP Offshore, or any
securities or other instruments convertible into or exchangeable for the
foregoing.

          (d) Except as listed in Schedule 2.5 and except for the rights of
Buyer hereunder, no Person has any right of first refusal, preemptive right,
subscription right or similar right with respect to any stock, securities or
equity interest in UP Offshore.

2.6   Subsidiaries.
      ------------

          (a) Exhibit 2.6 sets forth a complete and accurate organizational
chart of UP Offshore and all of its Subsidiaries, listing for each Subsidiary
its name, indicating its type of entity, the jurisdiction of its incorporation
or organization, and its ownership structure.

          (b) Other than the Subsidiaries, there are no other corporations,
partnerships, joint ventures, associations or other entities in which UP
Offshore or any Subsidiary owns, of record or beneficially, any direct or
indirect equity or other interest or any right (contingent or otherwise) to
acquire the same. Neither UP Offshore nor any Subsidiary is a member of any
partnership nor is UP Offshore or any Subsidiary a participant in any joint
venture or similar arrangement.

          (c) Each Subsidiary: (i) is duly organized, validly existing and in
good standing under the Laws of its jurisdiction of organization, (ii) has all
necessary power and authority to own, operate or lease the properties and assets
owned, operated or leased by such Subsidiary and to carry on its business as it
has been and is currently conducted by such Subsidiary, and (iii) is duly
licensed or qualified to do business and is in good standing in each
jurisdiction in which the properties owned or leased by it or the operation of
its business makes such licensing or qualification necessary or desirable, other
than those jurisdictions as to which the failure to be so licensed, qualified or
in good standing would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

          (d) All corporate actions taken by each Subsidiary have been duly
authorized and no Subsidiary has taken any action that in any respect conflicts
with, constitutes a default under or results in a violation of any provision of
its Certificate of Incorporation or By-laws (or similar organizational
documents).

2.7   Litigation; Observance of Agreements, Statutes and Orders.
      ---------------------------------------------------------

          (a) There are no actions, investigations, demands, suits or
proceedings pending or threatened against or affecting UP Offshore, any officer,
director or employee of UP Offshore or any property or business of UP Offshore,
the validity of this Agreement or the rights of Sellers to enter into this
Agreement or consummate the transactions contemplated hereby in any court or
agency or before any arbitrator of any kind or before or by any Governmental
Authority, that, individually or in the aggregate, could reasonably be expected
to have a Material Adverse Effect.

          (b) UP Offshore is not in default under or in violation of any term of
any agreement or instrument to which it is a party or by which it is bound, or
any Legal Requirement, which default or violation, individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect.

          (c) As of the date hereof and as of the Closing Date, no officer,
director or employee of UP Offshore is or will be subject to any non-competition
agreement, restrictive covenant or any other agreement restricting such person's
ability to work for, provide services to, or otherwise participate in UP
Offshore's business as currently contemplated.

2.8   Title to Property; Leases.
      -------------------------

          (a) UP Offshore has good and sufficient title to its owned personal
properties, tangible and intangible, and valid, binding and enforceable
leasehold interests in its leased personal properties that individually or in
the aggregate are Material, in each case free and clear of Liens other than in
respect of the mortgages on the vessels securing the indebtedness identified on
Schedule 2.10. All such personal property, other than vessels currently under
construction, is in working condition, ordinary wear and tear excepted. Such
properties constitute all of the personal properties necessary to operate UP
Offshore's business as currently conducted. All leasehold interests and
agreements of UP Offshore to such personal property are subsisting and
enforceable in accordance with their terms and, there does not exist thereunder
any default or event or condition which, after notice or lapse of time or both,
would constitute a default thereunder or which would have a Material Adverse
Effect on UP Offshore. Schedule 2.8(a) sets forth a brief description of all of
the assets of UP Offshore having a value in excess of Ten Thousand Dollars
($10,000).

          (b) UP Offshore has good and marketable title to all of its owned real
property, if any, and valid, binding and enforceable leasehold interests in its
leased real property, if any, that individually or in the aggregate are
Material, in each case free and clear of all Liens. Schedule 2.8(b) sets forth a
description of all real property owned by UP Offshore. All leasehold interests
and agreements of UP Offshore to its real property are subsisting and, there
does not exist thereunder any default or event or condition which, after notice
or lapse of time or both, would constitute a default thereunder or which would
have a Material Adverse Effect on UP Offshore. UP Offshore enjoys peaceful and
undisturbed possession under its leases of real property. Schedule 2.8(b) sets
forth a description of all leasehold interests in real property held by UP
Offshore.

2.9   Intellectual Property.
      ---------------------

            The only Intellectual Property owned by UP Offshore is the common
law trademark of its name and the registered domain name for its internet
website. UP Offshore is the exclusive owner of its Intellectual Property free
and clear of any Liens. To the Knowledge of the Sellers, the rights of UP
Offshore in the Intellectual Property it owns do not conflict with or infringe
on the rights of any other Person, and the Sellers have not received any claim
or written notice from any Person to such effect.

2.10  Indebtedness; Other Liabilities.
      -------------------------------

            Schedule 2.10 sets forth a complete and correct statement of the
Indebtedness of UP Offshore as of the date hereof. UP Offshore is not in default
with respect to any such Indebtedness, or any instrument or agreement relating
thereto. UP Offshore does not have any Indebtedness or liability, absolute or
contingent, liquidated or unliquidated, whether due or to become due, which is
not reflected on Schedule 2.10.

2.11  Material Contracts.
      ------------------

            Schedule 2.11 sets forth a list of Material Contracts of UP Offshore
as of the date hereof. The Seller has made available to Buyer for its review a
correct and complete copy of each such Material Contract. With respect to each
such Material Contract: (i) such contract is legal, valid, binding, enforceable,
and in full force and effect, (ii) such contract will continue to be legal,
valid, binding, enforceable, and in full force and effect on identical terms
following the consummation of the transactions contemplated hereby, and (iii) to
the Knowledge of Sellers, no party is in breach or default, and no event has
occurred which with notice or lapse of time or both would constitute a breach or
default, or permit termination, modification, or acceleration, under such
contract.

2.12  No Material Misstatements or Omissions; Disclosure.
      --------------------------------------------------

            No representation or warranty of the Seller in this Agreement
contains or will contain any untrue statement of a material fact nor shall such
representations and warranties taken as a whole omit any statement necessary in
order to make any material statement contained herein not misleading. There is
no fact that has not been disclosed hereunder to Buyer that might reasonably be
expected to have or result in a Material Adverse Effect on or with respect to UP
Offshore.

2.13  Broker's or Finder's Fees.
      -------------------------

            No broker, finder or similar agent has been employed by or on behalf
of the Seller, and no person or entity with which the Seller has had any
dealings or communications of any kind is entitled to any brokerage commission,
finder's fee or any similar compensation, in connection with this Agreement or
the transactions contemplated hereby.

2.14  Employees and Labor Relations.
      -----------------------------

            There is no labor strike, work stoppage or slowdown, picketing,
boycott, lockout or other labor dispute either pending or threatened, against UP

impair in any Material respect the operation or the conduct of UP Offshore's
business. UP Offshore is in compliance in all Material respects with all
applicable federal, state, and local laws respecting employment, fair employment
practices and fair labor standards, including, without limitation, race, age,
sex, religion, color, national origin, disability and sexual orientation.
Schedule 2.14 sets forth a list of all employees of UP Offshore.

2.15  Affiliate Transactions.
      ----------------------

            Schedule 2.15 contains an accurate and complete listing of all
contracts, leases, agreements or understandings, whether written or oral, with
or on behalf of any Affiliate of UP Offshore to which UP Offshore is a party or
is otherwise bound. None of such contracts, leases, agreements or understandings
contain terms that are more favorable than terms that would be obtainable from a
Person other than an Affiliate or that have been entered into by UP Offshore
other than in the ordinary course of business. Except as disclosed on Schedule
2.15, UP Offshore does not have any agreement, arrangement or understanding with
any of its Affiliates, the cancellation or termination of which would have a
Material Adverse Effect on UP Offshore.

2.16  Compliance with Laws.
      --------------------

            UP Offshore is in Material compliance with all Legal Requirements
and UP Offshore has not received notice of any complaint or order alleging any
Material non-compliance by UP Offshore with respect to any such Legal
Requirements.

2.17  Environmental Matters.
      ---------------------

            Seller has no Knowledge of any claim and has not received any notice
of any claim, and no proceeding has been instituted raising any claim against UP
Offshore or any of its properties now or formerly owned, leased or operated by
it or other assets, alleging any damage to the environment or violation of any
Environmental Laws, except, in each case, such as could not reasonably be
expected to result in a Material Adverse Effect. Seller has no Knowledge of any
facts which would give rise to any claim, public or private, of violation of
Environmental Laws or damage to the environment emanating from, occurring on or
in any way related to properties now or formerly owned, leased or operated by UP
Offshore or to other assets or their use, except, in each case, such as could
not reasonably be expected to result in a Material Adverse Effect. UP Offshore
has not stored any Hazardous Materials on properties now or formerly owned,
leased or operated by it other than in the ordinary course of business nor has
it disposed of any Hazardous Materials in a manner contrary to any Environmental
Laws in each case in any manner that could reasonably be expected to result in a
Material Adverse Effect. All buildings on all real properties now owned, leased
or operated by UP Offshore are in compliance with applicable Environmental Laws,
except where failure to comply could not reasonably be expected to result in a
Material Adverse Effect.

2.18  Securities Law.
      --------------

            In reliance on the investment representations contained in Sections
3.7 and 3.8, the offer, issuance, sale and delivery of the UP Offshore Shares,
as provided in this Agreement, are exempt from the registration requirements of
the Securities Act and all applicable state securities laws, and are otherwise
in compliance with such laws. Neither UP Offshore nor any Person acting on its
behalf has taken or will take any action which might subject the sale or
transfer of the UP Offshore Shares to the registration requirements of Section 5
of the Securities Act.

2.19  Registration Under Exchange Act.
      -------------------------------

            UP Offshore has not registered any class of its securities pursuant
to Section 12 of the Exchange Act and no such registration is required by the
Exchange Act. UP Offshore is not under any obligation to register, under the
Securities Act, any of its presently outstanding securities or any securities
which may hereafter be issued.

                    it or any of its properties or assets and will not result in
                    the creation or imposition of any lien, charge or

          5. Covenants. The Pledgor hereby covenants that during the continuance
of this Pledge Agreement:

               (i)  it shall warrant and defend the right and title of the
                    Pledgee conferred by this Pledge Agreement in and to its
                    Pledged Shares at the cost of the Pledgor against the claims
                    and demands of all persons whomsoever;

               (ii) except as herein provided, without the prior written consent
                    of the Pledgee, it shall not sell, assign, transfer, charge,
                    pledge or encumber in any manner any part of its Pledged
                    Shares or suffer to exist any encumbrance on its Pledged
                    Shares;

               (iii) without the prior written consent of the Pledgee, other
                    than as contemplated by the Stock Purchase Agreement, it
                    shall not amend or modify any organizational document,
                    by-law or other corporate governance agreement (including
                    any shareholders' agreement) relating to the Pledged
                    Company; and

               (iv) without the prior written consent of the Pledgee, it shall
                    not vote its Pledged Shares in favor of the consolidation,
                    merger, dissolution, liquidation or any other corporate
                    reorganization of the Pledged Company.

          6. Delivery of Additional Interests. If the Pledgor shall become
entitled to receive or shall receive any share certificates, option or rights,
whether as a dividend in respect of, in substitution of, or in exchange for any
of the Pledged Shares, the Pledgor agrees to accept the same as the agent of the
Pledgee and to hold the same in trust for the benefit of the Pledgee and to
deliver the same forthwith to the Pledgee in the exact form received, with the
endorsement of the Pledgor when necessary and/or appropriate undated instruments
of transfer duly executed in blank, and irrevocable proxy to be held by the
Pledgee, subject to the terms hereof, as additional collateral security for the
Obligations. Any sums paid upon or in respect of the Pledged Shares on the
liquidation or dissolution of any Pledged Company shall be paid over to the
Pledgee to be held by it as additional collateral security for the Obligations.

          7. Collateral. All property at any time pledged to the Pledgee
hereunder by the Pledgor (whether described herein or not) and all income
therefrom and proceeds thereof, are herein collectively sometimes called the
"Collateral".

          8. Voting Rights. The Pledgee shall, as the Pledgee and as the holder
of the Irrevocable Proxy, receive notice to vote the Pledged Shares at its own
discretion at, any annual or special meeting, as the case may be, of the
shareholders of the Pledged Company, provided, however, that the Pledgee shall
not exercise such right to vote until such time that default shall have occurred
in the payment or performance of the Obligations and not been remedied to the
Pledgee's satisfaction or waived in writing or any of the security created by or
pursuant to this Pledge Agreement shall be imperiled or jeopardized in a manner
deemed material by the Pledgee.

          9. Incorporation by Reference. This Pledge Agreement shall be read
together with the Stock Purchase Agreement, but in the case of any conflict with
the Stock Purchase Agreement, the Stock Purchase Agreement shall prevail.

          10. Enforcement/Satisfaction of Obligation. The security constituted
by this Pledge Agreement shall become immediately enforceable if,
subject to the exercise of the Buyer's Put Option contained in the Stock
Purchase Agreement, the Note shall not have been paid and either (i) the IPO
shall not have occurred by September 30, 2006 or (ii) the IPO shall have been
abandoned. At any time after the security constituted by this Pledge
Agreement shall have become enforceable as aforesaid, whereupon the security
constituted by this Pledge Agreement shall become enforceable, the Pledgee
shall be entitled, without further notice to the Pledgor to endorse the
Instrument of Transfer in its own name and to Cause the Company to register
the Pledged Shares in the name of the Pledgee as owner.  In such event, the
Pledgee hereby acknowledges that such transfer of the Pledged Shares shall
constitute satisfaction of the Obligations and the Pledgor shall be relieved
of any further liability or claim hereunder, under the Stock Purchase
Agreement or under the Note.

          11. No Duty on Pledgee. The Pledgee shall have no duty to exercise any
of the aforesaid rights, privileges or options and shall not be responsible for
any failure to do so or delay in so doing.

          12. Termination. When all of the Obligations shall have been fully
satisfied, or upon the successful completion of the IPO, as such term is defined
in the Stock Purchase Agreement, the Pledgee agrees that it shall forthwith
release each Pledgor from its Obligations hereunder and the Pledgee, at the
request and expense of the Pledgor, will promptly execute and deliver to the
Pledgor a proper instrument or instruments acknowledging the satisfaction and
termination of this Agreement, and the Irrevocable Proxy shall terminate
forthwith and be delivered to such Pledgor forthwith together with the other
items furnished to the Pledgee pursuant to Section 3 hereof.

          13. Changes in Writing; Successors and Assigns. None of the terms or
provisions of this Pledge Agreement may be waived, altered, modified or amended
except by an instrument in writing, duly executed by the Pledgee. This Pledge
Agreement and all obligations of the Pledgor hereunder shall be binding upon the
successors and assigns of the Pledgor and shall, together with the rights and
remedies of the Pledgee hereunder, inure to the benefit of the Pledgee, its
respective successors and assigns.

been or at the Closing will have been obtained by such Seller and will be in

          2.6 Company Organization and Capitalization.

          (a) Ravenscroft is a corporation, duly organized, validly existing and
in good standing under the laws of the Commonwealth of the Bahamas and is duly
qualified to do business and is in good standing in each jurisdiction in which
such qualification is required by law, other than those jurisdictions as to
which the failure to be so qualified or in good standing could not, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect.
Ravenscroft has the power and authority to own or hold under lease the
properties it purports to own or hold under lease, to transact the business it
transacts and proposes to transact. Other than the articles of incorporation and
the by-laws of Ravenscroft, there are no other agreements or documents to which
Ravenscroft or either Seller is a party with respect to the governance or
capitalization of Ravenscroft.

          (b) The authorized capital stock of Ravenscroft consists solely of 500
shares of common stock, par value $5,000 each. As of the date hereof and as of
the Closing Date, there are and shall be 500 shares of common stock issued and
outstanding and such shares shall constitute all of the issued and outstanding
shares of the capital stock of Ravenscroft. All such shares have been duly
authorized, validly issued and are fully paid and non-assessable. Upon
consummation of the Closing, Buyer will own 100% of the issued and outstanding
capital stock of Ravenscroft.

          (c) There are no outstanding obligations, warrants, options or other

any equity interest in Ravenscroft, or any securities or other instruments
convertible into or exchangeable for the foregoing.

          (d) Except for the rights of Buyer hereunder, no Person has any right
of first refusal, preemptive right, subscription right or similar right with
respect to any stock, securities or equity interest in Ravenscroft.

          2.7 Subsidiaries.

          (a) Exhibit 2.7 sets forth a complete and accurate organizational
chart of Ravenscroft and all of its Subsidiaries, listing for each Subsidiary
its name, indicating its type of entity, the jurisdiction of its incorporation
or organization, and its ownership structure.

          (b) Other than the Subsidiaries, there are no other corporations,
partnerships, joint ventures, associations or other entities in which
Ravenscroft or any Subsidiary owns, of record or beneficially, any direct or
indirect equity or other interest or any right (contingent or otherwise) to
acquire the same. Neither Ravenscroft nor any Subsidiary is a member of any
partnership nor is Ravenscroft or any Subsidiary a participant in any joint
venture or similar arrangement.

          (c) Each Subsidiary: (i) is a corporation duly organized, validly
existing and in good standing under the Laws of its jurisdiction of
incorporation, (ii) has all necessary power and authority to own, operate or
lease the properties and assets owned, operated or leased by such Subsidiary and
to carry on its business as it has been and is currently conducted by such
Subsidiary, and (iii) is duly licensed or qualified to do business and is in
good standing in each jurisdiction in which the properties owned or leased by it
or the operation of its business makes such licensing or qualification necessary
or desirable, other than those jurisdictions as to which the failure to be so
licensed, qualified or in good standing would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect.

          (d) All corporate actions taken by each Subsidiary have been duly
authorized and no Subsidiary has taken any action that in any respect conflicts
with, constitutes a default under or results in a violation of any provision of
its Certificate of Incorporation or By-laws (or similar organizational
documents).

          2.8 Litigation; Observance of Agreements, Statutes and Orders.

          (a) There are no actions, investigations, demands, suits or
proceedings pending or, to the Knowledge of Sellers, threatened against or
affecting any Ravenscroft Entity, any officer, director or employee of any
Ravenscroft Entity or any property or business of any Ravenscroft Entity, the
validity of this Agreement or the rights of Sellers to enter into this Agreement
or consummate the transactions contemplated hereby in any court or agency or
before any arbitrator of any kind or before or by any Governmental Authority,
that, individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect.

          (b) No Ravenscroft Entity is in default under or in violation of any
term of any agreement or instrument to which it is a party or by which it is
bound, or any Legal Requirement, which default or violation, individually or in
the aggregate, could reasonably be expected to have a Material Adverse Effect.

          (c) As of the date hereof and as of the Closing Date, no officer,
director or employee of any Ravenscroft Entity is or will be subject to any
non-competition agreement, restrictive covenant or any other agreement
restricting such person's ability to work for, provide services to, or otherwise
participate in such Ravenscroft Entity's business as currently contemplated.

          2.9 Title to Property; Leases.

          (a) Each Ravenscroft Entity has good and sufficient title to its
respective owned personal properties, tangible and intangible, and valid,
binding and enforceable leasehold interests in its leased personal properties
that individually or in the aggregate are Material, in each case free and clear
of Liens. All such personal property is in working condition, ordinary wear and
tear excepted. Such properties constitute all of the personal properties
necessary to operate such Ravenscroft Entity's business as currently conducted.
All leasehold interests and agreements of each Ravenscroft Entity to such
personal property are subsisting and enforceable in accordance with their terms
and to the Knowledge of Sellers, there does not exist thereunder any default or
event or condition which, after notice or lapse of time or both, would
constitute a default thereunder or which would have a Material Adverse Effect on
such Ravenscroft Entity. Schedule 2.9(a) sets forth a brief description of all
of the assets of each Ravenscroft Entity having a value in excess of Ten
Thousand Dollars ($10,000.00).

          (b) Each Ravenscroft Entity has good and marketable title to all of
its owned real property, if any, and valid, binding and enforceable leasehold
interests in its leased real property, if any, that individually or in the
aggregate are Material, in each case free and clear of all Liens. Schedule
2.9(b) sets forth a description of all real property owned by any Ravenscroft
Entity and any policy or contract of insurance held thereby in respect of such
property. All leasehold interests and agreements of such Ravenscroft Entity to
its respective real property are subsisting and to the Knowledge of Sellers,
there does not exist thereunder any default or event or condition which, after
notice or lapse of time or both, would constitute a default thereunder or which
would have a Material Adverse Effect on such Ravenscroft Entity. Each
Ravenscroft Entity enjoys peaceful and undisturbed possession under its
respective leases of real property. Schedule 2.9(b) sets forth a description of
all leasehold interests in real property held by each Ravenscroft Entity.

          2.10 Intellectual Property.

          No Ravenscroft Entity owns any registered trademark, copyright, logo
or patent other than the registered domain name for its respective internet
website. Each Ravenscroft Entity is the exclusive owner of its respective
Intellectual Property free and clear of any Liens. To the Knowledge of the
Sellers, the rights of each Ravenscroft Entity in the Intellectual Property it
owns do not conflict with or infringe on the rights of any other Person, and the
Sellers have not received any claim or written notice from any Person to such
effect.

          2.11 ERISA.

          The execution and delivery of this Agreement and the consummation of
the transactions hereunder will not involve any prohibited transaction within
the meaning of ERISA or Section 4975 of the Code and no condition exists or
event or transaction has occurred in connection with any Plan maintained or
contributed to by any Ravenscroft Entity or any ERISA Affiliate resulting from
the failure to comply with ERISA insofar as ERISA applies thereto which is
reasonably likely to result in a Ravenscroft Entity or any ERISA Affiliate
incurring any liability, fine or penalty which individually or in the aggregate
would have a material adverse effect on the Ravenscroft Group.

          2.12 Financial Statements.

          (a) Sellers have delivered to Buyer copies of the unaudited financial

independent contractor, creditor or other Person have been withheld and such
withheld Taxes have either been duly and timely paid to the proper Governmental
Authorities or shown as payables on the Financial Statements except for any
taxes and assessments: (i) the amount of which is not individually or in the
aggregate Material; or (ii) the amount, applicability or validity of which is
currently being contested in good faith by appropriate proceedings and with

Indebtedness of Ravenscroft Entity as of the date hereof. No Ravenscroft Entity
is in default with respect to any such Indebtedness, or any instrument or
agreement relating thereto. No Ravenscroft Entity has any Indebtedness or

become due, which is not reflected on Schedule 2.14.

          2.15 Material Contracts.

          Schedule 2.15 sets forth a list of Material Contracts of each

binding, enforceable, and in full force and effect, (ii) such contract will
continue to be legal, valid, binding, enforceable, and in full force and effect
on identical terms following the consummation of the transactions contemplated
hereby, and (iii) to the Knowledge of Sellers, no party is in breach or default,

constitute a breach or default, or permit termination, modification, or
acceleration, under such contract.

          2.16 No Material Misstatements or Omissions; Disclosure.

          No representation or warranty of Sellers in this Agreement contains or
will contain any untrue statement of a material fact nor shall such
representations and warranties taken as a whole omit any statement necessary in

contracts, leases, agreements or understandings, whether written or oral, with
or on behalf of any Affiliate of any Ravenscroft Entity to which such
Ravenscroft Entity is a party or is otherwise bound. None of such contracts,
leases, agreements or understandings contain terms that are more favorable than
terms that would be obtainable from a Person other than an Affiliate or that
have been entered into by such Ravenscroft Entity other than in the ordinary
course of business. Except as disclosed on Schedule 2.19, no Ravenscroft Entity

Sellers have no knowledge of any facts which would give rise to any claim,
public or private, of violation of Environmental Laws or damage to the
environment emanating from, occurring on or in any way related to properties now
or formerly owned, leased or operated by any Ravenscroft Entity or to other
assets or their use, except, in each case, such as could not reasonably be
expected to result in a Material Adverse Effect. No Ravenscroft Entity has

operated by it nor has it disposed of any Hazardous Materials in a manner
contrary to any Environmental Laws in each case in any manner that could

          2.22 Insurance.

          Sellers have delivered to Buyer true and complete copies of all
policies of insurance to which a Ravenscroft Entity is a party or under which
such Ravenscroft Entity is covered. All such policies are valid, outstanding and
enforceable and taken together provide adequate insurance coverage for the

as provided in this Agreement, are exempt from the registration requirements of
the Securities Act and all applicable state securities laws, and are otherwise
in compliance with such laws. Neither Ravenscroft nor any Person acting on its
behalf has taken or will take any action which might subject the sale or
transfer of the Ravenscroft Shares to the registration requirements of Section 5
of the Securities Act.

          2.25 Registration Under Exchange Act.

          Ravenscroft has not registered any class of its securities pursuant to

Securities Act, any of its presently outstanding securities or any securities
which may hereafter be issued.

          2.26. Vessel Management

          7.2 Indemnification.

          (a) Sellers agree to indemnify, defend and hold harmless Buyer, its

Notwithstanding anything to the contrary contained herein, Sellers shall not be

          (b) Buyer agrees to indemnify, defend and hold harmless Sellers, their
Affiliates and, if applicable, their respective directors, officers,
shareholders, employees, attorneys, accountants, agents and representatives and
their heirs, successors and assigns from and against any and all Damages based

breach of any representation or warranty, of Buyer contained in this Agreement,
or (ii) the failure of Buyer to perform or observe fully any covenant, agreement
or provision to be performed or observed by Buyer pursuant to this Agreement.

          7.3 Third-Party Claims.

          (a) If any party entitled to be indemnified pursuant to Section 7.2
(an "Indemnified Party") receives notice of the assertion of any claim in
respect of Damages, such Indemnified Party shall give the party who may become
obligated to provide indemnification hereunder (the "Indemnifying Party")
written notice describing such claim or fact in reasonable detail (the "Notice
of Claim") promptly (and in any event within 10 Business Days after receiving
any written notice from a third party). The failure by the Indemnified Party to
timely provide a Notice of Claim to the Indemnifying Party shall not relieve the
Indemnifying Party of any liability, except to the extent that the Indemnifying
Party is prejudiced by the Indemnified Party's failure to provide timely notice
hereunder.

          (b) In the event any Indemnifying Party notifies the Indemnified Party
within ten (10) Business Days after the Indemnified Party has given notice of
the matter that the Indemnifying Party is assuming the defense thereof: (i) the
Indemnifying Party will defend the Indemnified Party against the matter with
counsel of its choice reasonably satisfactory to the Indemnified Party; (ii) the
Indemnified Party may retain separate co-counsel at its sole cost and expense
(except that the Indemnifying Party will be responsible for the fees and
expenses of the separate co-counsel to the extent the Indemnified Party
reasonably concludes that the counsel the Indemnifying Party has selected has a
conflict of interest); (iii) the Indemnified Party will not consent to the entry
of any judgment or enter into any settlement with respect to the matter without
the written consent of the Indemnifying Party which consent shall not be
unreasonably withheld; and (iv) the Indemnifying Party will not consent to the
entry of any judgment with respect to the matter, or enter into any settlement
which does not include a provision whereby the plaintiff or claimant in the
matter releases the Indemnified Party from all liability with respect thereto,
and, in a settlement or compromise which does not involve only the payment of
money by the Indemnifying Party, without the prior written consent of the
Indemnified Party which consent shall not be unreasonably withheld.

          (c) In the event the Indemnifying Party does not notify the
Indemnified Party within ten (10) Business Days after the Indemnified Party has
received a Notice of Claim that the Indemnifying Party is assuming the defense
thereof, then the Indemnified Party shall have the right, subject to the
provisions of this Article, to undertake the defense, compromise or settlement
of such Claim for the account of the Indemnifying Party. Unless and until the
Indemnifying Party assumes the defense of any Claim, the Indemnifying Party
shall advance to the Indemnified Party any of its reasonable attorneys' fees and
other costs and expenses incurred in connection with the defense of any such
action or proceeding. Each Indemnified Party shall agree in writing prior to any
such advance that, in the event it receives any such advance, such Indemnified
Party shall reimburse the Indemnifying Party for such fees, costs and expenses
to the extent that it shall be determined that it was not entitled to
indemnification under this Article VI.

          (d) In the event that the Indemnifying Party undertakes the defense of
any Claim, the Indemnifying Party will keep the Indemnified Party advised as to
all material developments in connection with such Claim, including, but not
limited to, promptly furnishing the Indemnified Party with copies of all
material documents filed or served in connection therewith.

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

          THIS PLEDGE AGREEMENT (this "Pledge Agreement") is made this 20th day
of March, 2006, by and among ULTRAPETROL (BAHAMAS) LIMITED, a company organized
under the laws of The Bahamas (the "Pledgor), and CROSSTRADE MARITIME INC., a
company organized under the laws of the Republic of Liberia ("Crosstrade"), and
CROSSTREES MARITIME INC., a company organized under the laws of the Republic of
Liberia ("Crosstrees", and together with Crosstrade, the "Pledgees") as
pledgees, pursuant to the terms of that stock purchase agreement dated as of
March 20, 2006 made by and among the Pledgor, as buyer, and the Pledgees, as
sellers, (the "Stock Purchase Agreement") in connection with the Pledgor's
purchase of 500 shares of common stock of Ravenscroft Shipping (Bahamas) S.A.
("Ravenscroft" or "Pledged Company").

                                   WITNESSETH:
                                   -----------

     WHEREAS:

               Pursuant to the terms of the Stock Purchase Agreement, the Buyer
has executed and delivered promissory note to each Pledgee (the "Notes") of even
date herewith in the amount of $5,750,000 in payment of the purchase price of
the Pledged Shares (as defined below);

               As of the date hereof, the Buyer is the registered and beneficial
owner of 500 shares of capital stock of Ravenscroft (the "Pledged Shares");

               Pursuant to the terms of the Stock Purchase Agreement, the Buyer
shall execute and deliver to the Pledgees, as security for the obligations of
the Buyer under the Stock Purchase Agreement and the Notes, a pledge of all of
Pledgor's right, title and interest in and to the Pledged Shares;

          NOW, THEREFORE, in consideration of the premises set forth herein, the
Pledgors agree with the Pledgee as follows:

          1. Defined Terms. Unless otherwise defined herein, terms defined in
the Stock Purchase Agreement shall have the same meanings when used herein.

          2. Grant of Security. As security for the full and prompt payment of
the Notes to the Pledgees and the performance of the Pledgor's obligations under
the Stock Purchase Agreement (collectively, the "Obligations"), the Pledgor
hereby pledges, assigns, transfers and delivers to the Pledgees the Pledged
Shares and hereby grants to the Pledgees a first lien on, and first security
interest in, the Pledged Shares. Notwithstanding anything to the contrary herein
provided, the rights of the Pledgees in and to the Pledged Shares are several
and not joint.

          3. Pledge Documents. Concurrently with the execution of this Pledge
Agreement, the Pledgor shall execute and deliver to each Pledgee an Irrevocable
Proxy in favor of each Pledgee in respect of 250 of the Pledged Shares in the
form set out in Exhibit A hereto (each, an "Irrevocable Proxy" and collectively,
the "Irrevocable Proxies") and shall deliver to the Pledgees the certificates
representing such Pledged Shares together with signed, undated instruments of
transfer (the "Instruments of Transfer") pertaining thereto duly executed in
blank.

          4. Representations and Warranties. The Pledgor represents and warrants
that:

                    (i) it is the legal and beneficial owner of, and has good
and marketable title to, its Pledged Shares, subject to no pledge, lien,
mortgage, hypothecation, security interest, charge, option or other encumbrance
whatsoever, except the lien and security interest created by this Pledge
Agreement and the delivery of the Pledged Shares to each Pledgee;

                    (ii) it has full power, authority and legal right to
execute, deliver and perform this Pledge Agreement and to create the collateral
security interest for which this Pledge Agreement provides;

                    (iii) the Pledged Shares have been duly and validly created
and issued and are fully paid and nonassessable;

                    (iv) this Pledge Agreement constitutes a valid obligation of
the Pledgor, legally binding upon it and enforceable in accordance with its
terms;

                    (v) no consent of any other party that has not been obtained
is required in connection with the execution, delivery, performance, validity,
enforceability or enforcement of this Pledge Agreement, and no consent, license,
approval or authorization of, or registration or declaration with, any
governmental authority, bureau or agency is required in connection with the
execution, delivery, performance, validity, enforceability or enforcement of
this Pledge Agreement;

                    (vi) the execution, delivery and performance of this Pledge
Agreement will not violate or contravene any provision of any existing law or
regulation or decree of any court, governmental authority, bureau or agency
having jurisdiction in the premises or of the charter documents of the Pledgor
or of any mortgage, stock purchase agreement, security agreement, contract,
undertaking or other agreement to which the Pledgor is a party or which purports
to be binding upon it or any of its properties or assets and will not result in
the creation or imposition of any lien, charge or encumbrance on, or security
interest in, any of its properties or assets pursuant to the provisions of any
such mortgage, stock purchase agreement, security agreement, contract,
undertaking or other agreement;

          5. Covenants. The Pledgor hereby covenants that during the continuance
of this Pledge Agreement:

                    (i) it shall warrant and defend the right and title of the
Pledgees conferred by this Pledge Agreement in and to its respective Pledged
Shares at the cost of the Pledgor against the claims and demands of all persons
whomsoever;

                    (ii) except as herein provided, without the prior written
consent of the Pledgees, it shall not sell, assign, transfer, charge, pledge or
encumber in any manner any part of its respective Pledged Shares or suffer to
exist any encumbrance on its respective Pledged Shares;

                    (iii) without the prior written consent of the Pledgees,
other than as contemplated by the Stock Purchase Agreement, it shall not amend
or modify any organizational document, by-law or other corporate governance
agreement (including any shareholders' agreement) relating to the Pledged
Company; and

                    (iv) without the prior written consent of the Pledgees, it
shall not vote its respective Pledged Shares in favor of the consolidation,
merger, dissolution, liquidation or any other corporate reorganization of the
Pledged Company;

          6. Delivery of Additional Interests. If the Pledgor shall become
entitled to receive or shall receive any share certificates, option or rights,
whether as an addition to, in substitution of, or in exchange for any of the
Pledged Shares, the Pledgor agrees to accept the same as the agent of the
Pledgees and to hold the same in trust for the benefit of the Pledgees and to
deliver the same forthwith to the Pledgees in the exact form received, with the
endorsement of the Pledgor when necessary and/or appropriate undated instruments
of transfer duly executed in blank, and irrevocable proxies to be held by the
Pledgees, subject to the terms hereof, as additional collateral security for the
Obligations. Any sums paid upon or in respect of the Pledged Shares on the
liquidation or dissolution of any Pledged Company shall be paid over to the
Pledgees to be held by it as additional collateral security for the Obligations.

          7. Collateral. All property at any time pledged to the Pledgees
hereunder by the Pledgor (whether described herein or not) and all income
therefrom and proceeds thereof, are herein collectively sometimes called the
"Collateral".

          8. Voting Rights. The Pledgees shall, as the Pledgees and as the
holders of the Irrevocable Proxies, receive notice to vote the Pledged Shares at
their own discretion at any annual or special meeting, as the case may be, of
the shareholders of any Pledged Company, provided, however, that the Pledgees
shall not exercise such right to vote until such time that default shall have
occurred in the payment or performance of the Obligations and not been remedied
to the Pledgees' satisfaction or waived in writing or any of the security
created by or pursuant to this Pledge Agreement shall be imperiled or
jeopardized in a manner deemed material by the Pledgees.

          9. Incorporation by Reference. This Pledge Agreement shall be read
together with the Stock Purchase Agreement, but in the case of any conflict with
the Stock Purchase Agreement, the Stock Purchase Agreement shall prevail.

          10. Enforcement/Satisfaction of Obligation. The security constituted
by this Pledge Agreement shall become immediately enforceable if, subject to the
exercise of the Buyer's Put Option contained in the Stock Purchase Agreement,
the Note shall not have been paid and either (i) the IPO shall not have occurred
by September 30, 2006, or (ii) the IPO shall have been abandoned.

          At any time after the security constituted by this Pledge Agreement
shall have become enforceable as aforesaid, whereupon the security constituted
by this Pledge Agreement shall become enforceable, the Pledgees shall be
entitled, without further notice to the Pledgor:

               (i) to endorse the Instrument of Transfer in its own name and to
cause the Company to register the Pledged Shares in the name of the Pledgees as
owner.

     In such event, the Pledgee hereby acknowledges that such transfer of the
Pledged Shares shall constitute satisfaction of the Obligations and the Pledgor
shall be relieved of any further liability or claim hereunder, under the Stock
Purchase Agreement or under the Note.

          11. No Duty on Pledgees. The Pledgees shall have no duty to exercise
any of the aforesaid rights, privileges or options and shall not be responsible
for any failure to do so or delay in so doing.

          12. Termination. When all of the Obligations shall have been fully
satisfied, or upon the successful completion of the IPO, as such term is defined
in the Stock Purchase Agreement, the Pledgees agree that each thereof shall
forthwith release the Pledgor from its Obligations hereunder and the Pledgees,
at the request and expense of the Pledgor, will promptly execute and deliver to
the Pledgor a proper instrument or instruments acknowledging the satisfaction
and termination of this Agreement, and the Irrevocable Proxies shall terminate
forthwith and be delivered to the Pledgor forthwith together with the other
items furnished to the Pledgees pursuant to Section 3 hereof.

          13. Changes in Writing; Successors and Assigns. None of the terms or
provisions of this Pledge Agreement may be waived, altered, modified or amended
