                  limited liability company (the "Borrower"), AMERICAN
                  COMMERCIAL LINES HOLDINGS LLC, a Delaware limited liability
                  company ("Holdings"), the Lenders listed on the signature
                  pages herein, and JPMORGAN CHASE BANK, a New York banking
                  corporation formerly named The Chase Manhattan Bank, as
                  issuing bank (in such capacity, the "Issuing Bank"), as
                  administrative agent (in such capacity, the "Administrative
                  Agent"), as security trustee (in such capacity, the "Security
                  Trustee") and as collateral agent (in such capacity, the
                  "Collateral Agent") for the Lenders.

      A. Reference is made to the Credit Agreement dated as of June 30, 1998, as
amended prior to the Restatement Closing Date (as defined below) (the "Original
Credit Agreement"), among Holdings, the Borrower, the Lenders party thereto, the
Issuing Bank, the Administrative Agent, the Security Trustee and the Collateral
Agent pursuant to which (a) the Lenders made Tranche B Term Loans to the
Borrower in an aggregate principal amount equal to $200,000,000 (of which
$[143,950,889] is outstanding as of the date hereof), (b) the Lenders made
Tranche C Term Loans in an aggregate principal amount equal to $235,000,000 (of
which $[169,378,111] is outstanding as of the date hereof), (c) the Lenders
extended and agreed to extend credit to the Borrower in the form of Revolving
Loans in an aggregate principal amount at any time outstanding not in excess of
$100,000,000 and (d) the Issuing Bank issued and agreed to issue letters of
credit, in an aggregate face amount at anytime outstanding not in excess of

      B. Holdings, the Borrower, the Required Lenders, the Issuing Bank, the
Administrative Agent, the Security Trustee and the Collateral Agent have agreed,
subject to the terms and conditions contained herein and pursuant to the voting
provisions set forth in the Original Credit Agreement, that the Original Credit
Agreement (including all exhibits and schedules thereto) be amended and restated
in its entirety in the form of the Amended and Restated Credit Agreement set
forth as Exhibit A hereto and without any further action on the part of the
Lenders (the "Amended and Restated Credit Agreement"), provided that until such
time, the Original Credit Agreement shall remain in full force and effect
(subject to the terms of the Forbearance Agreement which shall remain effective
until the earliest to occur of the New Forbearance Termination Date, a
Forbearance Default (as each such term is defined in the Forbearance Agreement)
and the Restatement Closing Date).

      C. On the Restatement Closing Date, subject to the consummation of the
other Transactions, (a) $50,000,000 of the then outstanding Revolving Credit
<PAGE>
Borrowings shall be converted into Tranche A Term Loans and the Revolving Credit
Commitments permanently reduced by such amount and (b) the Borrower shall prepay
not less than $25,000,000 aggregate principal amount of the outstanding Term
Loans (the "Restatement Prepayment").

      D. In connection with the Restructuring, on the Restatement Closing Date a
newly formed, direct or indirect wholly owned subsidiary of DHC shall be merged
with and into Holdings pursuant to Section 2.5 of the Recapitalization
Agreement, with Holdings as the surviving entity (the "Holdings Merger").

      E. Accordingly, in consideration of the mutual agreements herein contained
and other good and valuable consideration, the sufficiency and receipt of which
are hereby acknowledged, the parties hereto hereby agree as follows:

      SECTION 1. Defined Terms. Capitalized terms used and not defined herein
shall have the meanings assigned to such terms in the Amended and Restated
Credit Agreement.

      SECTION 2. Amendment and Restatement of the Original Credit Agreement. (a)
Holdings, the Borrower, the Required Lenders, the Issuing Bank, the
Administrative Agent, the Security Trustee and the Collateral Agent agree that
the Original Credit Agreement (including all exhibits and schedules thereto) is
hereby amended and restated, such that on the Restatement Closing Date, the
terms set forth in Exhibit A hereto shall replace the terms of the Original
Credit Agreement. As used in the Amended and Restated Credit Agreement, the
terms "Agreement", "this Agreement", "herein", "hereinafter", "hereto", "hereof"
and words of similar import shall, unless the context otherwise requires, mean,
from and after the replacement of the terms of the Original Credit Agreement by
the terms of the Amended and Restated Credit Agreement, the Amended and Restated
Credit Agreement.

      (b) On the Restatement Closing Date and upon the replacement of the terms
of the Original Credit Agreement by the terms of the Amended and Restated Credit
Agreement, (i) $50,000,000 of the then outstanding Revolving Credit Borrowings
shall be converted into Tranche A Term Loans and the Revolving Credit
Commitments permanently reduced by such amount and (ii) the Borrower shall make
the Restatement Prepayment.

      SECTION 3. Representations and Warranties. The Borrower hereby makes to
each of the other parties hereto, on and as of the Restatement Closing Date,
each of the representations and warranties contained in Article III of the
Amended and Restated Credit Agreement, except to the extent such representations
and warranties expressly relate to an earlier date, and each of such
representations and warranties is hereby incorporated by reference herein.

      SECTION 4. Fees. On the Restatement Closing Date, the Borrower agrees to
pay a fee (the "Amendment Fee") to each Lender that executes and delivers to the
Administrative Agent (or its counsel) a signature page to this Agreement on or
prior to


                                       2
<PAGE>
April 11, 2002, through the Administrative Agent, in an amount equal to 0.375%
of the sum of (a) the outstanding Term Loans of such Lender and (b) the
Revolving Credit Commitment (whether used or unused) of such Lender, in each
case immediately prior to the replacement of the terms of the Original Credit
Agreement with the terms of the Amended and Restated Credit Agreement and
without giving effect to the conversion of any Revolving Loans into Term Loans
or the Restatement Prepayment. The Amendment Fee shall be payable on the
Restatement Closing Date in immediately available funds. Once paid, the
Amendment Fee shall not be refundable under any circumstances.

      SECTION 5. Conditions to the Replacement of the Original Credit Agreement
by the Amended and Restated Credit Agreement. The terms of the Amended and

Nothing expressed or implied in this Agreement, the Amended and Restated Credit
Agreement or any other document contemplated hereby or thereby shall be

13 hereof. Delivery of an executed signature page to this Agreement by facsimile
transmission shall be as effective as delivery of a manually signed counterpart

consideration in interpreting this Agreement.

      SECTION 13. Effectiveness. This Agreement shall become effective when it
shall have been executed by the Borrower, Holdings and the Administrative Agent
and when the Administrative Agent shall have required counterparts hereof which,
when taken together, bear the signatures of the Required Lenders, and thereafter
shall be binding upon and inure to the benefit of Holdings, the Borrower, the
Administrative Agent, the Collateral Agent, the Security Trustee, the Issuing
Bank and each Lender and their respective permitted successors and assigns.
