                              ARTICLE 1 - GUARANTEE

1.01  Guarantee

      The Guarantor hereby unconditionally and irrevocably guarantees payment of
the Guaranteed Obligations; provided that the recourse of the Secured Parties

1.02  Obligations Absolute

      The liability of the Guarantor hereunder will be absolute and

      (a)   any lack of validity or enforceability of any agreement between the
            Borrower and the Secured Parties;

      (b)   any impossibility, impracticability, frustration of purpose,
            illegality, force majeure or act of government;

            the Borrower, the Guarantor, the Secured Parties or any other
            person;

      (d)   any lack or limitation of power, incapacity or disability on the
            part of the Borrower or of the directors, partners or agents thereof
            or any other irregularity, defect or informality on the part of the
            Borrower in its obligations to the Secured Parties; or

      (e)   any other law, regulation or other circumstance that might otherwise
            constitute a defence available to, or a discharge of, the Borrower
            in respect of any or all of the Obligations.

                  ARTICLE 2 - DEALINGS WITH BORROWER AND OTHERS

2.01  No Release

      The liability of the Guarantor hereunder will not be released, discharged,

of any security received by the Secured Parties from the Borrower or others.
Without limiting the generality of the foregoing and without releasing,

liability hereunder, without obtaining the consent of or giving notice to the
Guarantor, the Secured Parties may:

      (a)   discontinue, reduce, increase or otherwise vary the credit of the
            Borrower in any manner whatsoever; provided, that the principal

            Borrower shall not be increased by more than $500,000 absent
            Guarantor's prior written consent;

      (b)   make any change in the time, manner or place of payment under, or in
            any other term of, any agreement between the Borrower and the
            Secured Parties or the failure on the part of the Borrower to carry
            out any of its obligations under any such agreement;

      (c)   grant time, renewals, extensions, indulgences, releases and
            discharges to the Borrower;

            time to time as the Secured Parties may see fit; or

      (g)   otherwise deal with the Borrower and all other persons and
            securities as the Secured Parties may see fit.

2.02  No Exhaustion of Remedies

recourse against the Borrower or other persons or any securities or collateral
any may hold or take any other action before being entitled to demand payment
from the Guarantor hereunder.

2.03  No Set-Off

      In any claim by the Secured Parties against the Guarantor, the Guarantor

                               ARTICLE 3 - DEMAND

3.01  Demand

      Upon the occurrence of any Triggering Event (as hereafter defined), the
Agent will be entitled to make demand upon the Guarantor for the payment of any
or all of the Guaranteed Obligations as set forth under Section 3.02 below. For
the purposes of this Agreement, the occurrence of any of the following events
shall constitute a "Triggering Event":

      (a)   the Debt Service Coverage Ratio of Voyageur Maritime Holdings Inc.
            ("Holdings") and its Subsidiaries shall on a consolidated basis be
            less than 1.10:1.00 on any date on which it is tested under the
            Credit Agreement except that, for the Fiscal Quarter ending April



            30, 2008, a Triggering Event shall instead occur if the Debt Service
            Coverage Ratio of Holdings and its Subsidiaries shall on a
            consolidated basis be less than 0.8:1.0 in respect of the period
            commencing on the Closing Date and ending on April 30, 2008;

      (b)   the amount outstanding under the Term Loan shall exceed the sum of
            (i) 100% of the orderly liquidation value of the Financed Vessel
            less (ii) the amount secured by Liens attaching to the Financed
            Vessel that have or may have priority to the Agent's Lien over the
            Financed Vessel;

      (c)   the Borrower and Transport shall have (i) failed to make the
            Financed Vessel available to the Guarantor for loaded voyages at any
            time during the Navigation Season (as defined in the COA) for any
            reason (including force majeure) or (ii) otherwise have breached,
            defaulted under, or failed to perform under, the COA (any
            non-declaration or waiver of breach, default or non-performance by
            the Guarantor under the COA being ineffective for purposes of this
            Section 3.01(c)); or

      (d)   an Event of Default shall occur under Section 8.1(a), (h) or (i) of
            the Credit Agreement.

3.02  Procedure for Exercise of Draw

      If the Agent wishes to demand payment under the Guarantee, whether
pursuant to a draw on the Letter of Credit or otherwise, the Agent shall give
notice in writing of its intention to demand payment to the Guarantor at the
address shown in Section 5.06 (the "Trigger Notice"). The Trigger Notice shall
contain a description of the Triggering Event in respect of which the Trigger
Notice is delivered. Except in respect of a Triggering Event arising from an
Event of Default under Section 8.1(h) or (i) of the Credit Agreement (upon which
payment shall be due immediately and a draw may immediately be made under the
Letter of Credit at the Agent's sole discretion), payment under the Guarantee
shall be due on the 60th day (the "Draw Date") after the Guarantor's receipt of
such Trigger Notice (upon which date a draw may be made under the Letter of
Credit at the Agent's sole discretion) unless, prior to the Draw Date:

      (a)   the Guarantor has completed its purchase of the Financed Vessel in
            accordance with the Option Agreement; or

      (b)   the Guarantor (either alone or together with Heddle Marine Service
            Inc.) has made a subordinated secured loan (the "Subordinated
            Secured Loan") to the Borrower in an amount at least equal to the
            amount of the Guaranteed Obligations and otherwise on terms and
            conditions reasonably satisfactory to the Agent, and all or a
            portion of the proceeds of such loan in an amount at least equal to
            the amount of the Guaranteed Obligations has been paid over by the
            Guarantor to the Agent at the direction of the Borrower; or

      (c)   all Trigger Events have been cured or waived by the Agent.



3.03  Buy-Out Option

      Within fifteen (15) days following the receipt by the Guarantor of any
notice from the Agent of an Event of Default arising under Section 8.1(h) or (i)
of the Credit Agreement (which notice has not been withdrawn in writing by the
Agent prior to the delivery of a Committed Buy-Out Notice (as hereinafter
defined)), (i) the Guarantor shall have the right (the "Purchase Option"), by
giving a written notice (a "Committed Buy-Out Notice") to the Agent to acquire
on the date that is five (5) Business Days after the date of the Agent's receipt
of such Committed Buy-Out Notice, from the Secured Parties all (but not less
than all) of the right, title, and interest of the Secured Parties in and to the
Obligations and the Loan Documents, and (ii) upon the receipt by the Agent of
the Committed Buy-Out Notice, Guarantor irrevocably shall be committed to
acquire, within five (5) Business Days following such receipt, from the Secured
Parties all (but not less than all) of the right, title, and interest of the
Secured Parties in and to the Obligations and the Loan Documents, by paying to
the Agent in cash a purchase price (the "Purchase Price") equal to the sum of:

      (a)   100% of the outstanding balance with respect to the Term Loan owing
            to the Lenders, including, without limitation, principal, interest
            accrued and unpaid thereon, and any unpaid fees, to the extent
            earned or due and payable in accordance with the Loan Documents, and

      (b)   100% of the expenses to the extent earned or due and payable to the
            Secured Parties in accordance with the Loan Documents (including the
            reimbursement of extraordinary expenses, attorneys fees, financial
            examination expenses and appraisal fees);

whereupon the Secured Parties shall assign to Guarantor, without any
representation, recourse, or warranty whatsoever (except that each applicable
Secured Party shall warrant to Guarantor that (1) the amount quoted in writing
by such Secured Party as its portion of the Purchase Price represents the amount
shown as due with respect to the claims transferred as reflected on its books
and records, (2) it owns, or has the right to transfer to Guarantor, the rights
being transferred, and (3) the assets being transferred will be free and clear
of Liens and adverse claims), their right, title, and interest with respect to
the Obligations and the Loan Documents.

      The assignment by the Secured Parties of their right, title, and interest
with respect to the Obligations and the Loan Documents shall be at no expense
(other than the payment of the applicable Purchase Price) to Guarantor other
than the reimbursement by Guarantor of the reasonable out-of-pocket expenses of
the Secured Parties (including their attorneys fees) in connection with
documenting and effecting such assignment and the related delivery to Guarantor
of the original Loan Documents in the possession of such Secured Parties. In
connection with such assignment, the Secured Parties shall deliver to Guarantor
any original Loan Documents and any Collateral in their possession and shall
execute such other documents, instruments, and agreements reasonably necessary
to effect such assignment, whereupon such Secured Parties shall be relieved from
any further duties, obligations, or liabilities to Guarantor pursuant to this
Agreement.



      For greater certainty, no Secured Party shall be under any obligation
pursuant to this Agreement to approve any new credit facility or amend the terms
of any existing credit facility for the account of the Guarantor or Heddle
Marine Service Inc. for the purpose of assisting either of them to fund the
Purchase Price.

3.04  Letter of Credit

      All payments made by a draw under the Letter of Credit shall reduce any
amount due hereunder on a dollar for dollar basis.

                             ARTICLE 4 - SUBROGATION

4.01  Subrogation

      The Guarantor will not be entitled to subrogation until (i) the Guarantor
performs or makes payment to the Secured Parties of all amounts owing by the
Guarantor to the Secured Parties under this Guarantee and (ii) the Obligations
are performed and paid in full in cash. Thereafter, the Secured Parties will, at
the Guarantor's request and expense, execute and deliver to the Guarantor
appropriate documents, without recourse and without representation and warranty,
necessary to evidence the transfer by subrogation to the Guarantor of an
interest in the Obligations and any security held therefor resulting from such
performance or payment by the Guarantor.

                               ARTICLE 5 - GENERAL

5.01  Representation and Warranty of the Guarantor

      The Guarantor represents and warrants that that it has not had commenced
and served or threatened against it by Canada Steamship Lines Inc. ("CSL") or
the Seafarers' International Union of Canada ("SIU") any litigation, labor
action, or other claim in connection with its charter of the Financed Vessel,
the operation of the Financed Vessel on the Great Lakes or St. Lawrence Seaway,
or the potential acquisition of the Financed Vessel by the Guarantor.

will enure to the benefit of the Secured Parties and their respective successors
and permitted assigns.

5.03  Entire Agreement

      This Guarantee constitutes the entire agreement between the Guarantor and
the Secured Parties with respect to the subject matter hereof and cancels and
supersedes any prior understandings and agreements between such parties with
respect thereto. There are no representations, warranties, terms, conditions,
undertakings or collateral agreements, express, implied or statutory, between
the parties except as expressly set forth herein. The Secured Parties will not
be bound by any representations or promises made by the Borrower to the
Guarantor, and possession of this Guarantee by the Secured Parties will be
conclusive evidence against the Guarantor that the Guarantee was not delivered
in escrow or pursuant to any agreement that it should not be effective until any



condition precedent or subsequent has been complied with and this Guarantee will
be operative and binding notwithstanding the non-execution thereof by any
proposed signatory.

5.04  Amendments and Waivers

      No amendment to this Guarantee will be valid or binding unless set forth
in writing and duly executed by the Guarantor and the Agent. No waiver of any
breach of any provision of this Guarantee will be effective or binding unless
made in writing and signed by the party purporting to give the same and, unless
otherwise provided in the written waiver, will be limited to the specific breach
waived.

5.05  Severability

      If any provision of this Guarantee is determined to be invalid or
unenforceable in whole or in part, such invalidity or unenforceability will

effect.
