 ARTICLE 2 
  
 THE CREDIT LINE  
  
 Section 2.01 The Credit Line and the Credit Loan. (a) The parties acknowledge and agree that immediately preceding the effectiveness of this Agreement, the
outstanding principal amount of advances under the 2001 Credit Agreement was $51,900,000.00 in the aggregate, $10,380,000.00 of which was owed by the Borrowers to Hibernia National Bank, $10,380,000.00 to Fortis Capital Corp., $10,380,000.00 to
Southwest Bank of Texas, N.A., $10,380,000.00 to DVB Bank Aktiengesellschaft and $10,380,000.00 to Wells Fargo, N.A. Such advances shall be restated on the Effective Date and be considered Advances made by the Banks to the Borrowers consistent with
the Commitments hereunder; no novation is intended hereby. Subject to and upon the terms and conditions set forth in this Agreement, and relying upon the representations and warranties contained in this Agreement, each Bank, severally, is willing to
make multiple Advances to the Borrowers under the Credit Line prior to the Maturity Date in the aggregate principal amount up to such Bank’s Borrowing Base Credit Commitment set forth on Schedule 1 hereto. The aggregate amount of the
Advances cannot exceed the Credit Limit. The Credit Line shall be revolving, such that from the Effective Date through the Business Day immediately preceding the Maturity Date, the Borrowers may borrow, repay and reborrow under the Credit Line. The
Credit Loan and Advances thereunder will be evidenced by a Credit Note for each Bank in the principal amount, initially, of such Bank’s Credit Commitment. Interest on the Credit Line shall accrue as described in Section 2.03 hereof and shall be
payable, in arrears, also as provided in Section 2.03. The Credit Notes shall mature and be payable in full (including without limitation all then outstanding principal and accrued and unpaid interest) on the Maturity Date. 
  
 (b) ANY ADVANCE HEREUNDER TO OR ON BEHALF OF A BORROWER SHALL BE DEEMED FOR ALL
PURPOSES TO BE AN ADVANCE TO BOTH BORROWERS. EACH BORROWER HEREBY ACKNOWLEDGES AND AGREES THAT IT IS SOLIDARILY (JOINTLY AND SEVERALLY) LIABLE WITH THE OTHER BORROWER TO THE BANKS FOR THE PAYMENT AND PERFORMANCE OF ALL ADVANCES AND ANY OTHER
OBLIGATIONS INCURRED OR FROM TIME TO TIME DUE AND PAYABLE. 
  
 Section
2.02 Manner and Notice of Advances Under the Credit Line. Subject to the requirements and limitations set forth in this Section 2.02 and in Article 7 hereof, Advances may be drawn solely for the purposes set forth in Section 2.10 hereof.

  
 Borrowers shall provide the Agent with any request for an Advance (i)
prior to 10:00 a.m. (central time) at least two (2) Business Days prior to the requested date of the Advance to initially accrue interest based on the Floating Rate and (ii) at least one (1) Business Day prior to the requested date of the Advance to
initially accrue interest based on the Prime Rate, in each case pursuant to a Draw Request Certificate (the “Draw Request Certificate”), the form of which is attached hereto as Exhibit B. If the Advance is in connection with
the acquisition of a company or assets of another company (other than in the ordinary course of business), then Borrowers shall provide to the Agent such other information in connection therewith as the Agent requests, including without limitation
compliance with subsection 2.01(a) and Section 6.05 hereof if applicable. The Agent will use its best efforts to give telephone notice to the Banks of a proposed Advance on the same day such Draw Request Certificate is received by the Agent from
Borrowers, but in any event (x) at least two (2) Business Days prior to any Advance to initially accrue interest based on the Floating Rate interest option, and (y) at least one (1) Business Day prior to any Advance to initially accrue interest
based on the Prime Rate interest option. Advances shall be made only on Business Days. The request for any Advance shall constitute a certification by Borrowers that all of the representations and warranties contained in Article 4 (other than those

  

 14 








 representations and warranties that are, by their specific terms, limited in application to a specific date) are true and correct
as of the date of such request and also as of the date of the Advance. 
  
 Not later than 12:00 noon (central time) on the date of any Advance, each of the Banks shall make available to the Agent, in immediately available funds, the amount of such Bank’s pro rata portion (i.e., the percentage of its Credit
Commitment as compared to the aggregate of the Credit Commitments) of the amount of the requested Advance. Upon receipt from each Bank of such amount, and upon fulfillment of the applicable conditions set forth in Sections 7.01 or 7.02 hereof, the
Agent (on behalf of the Banks) will make available to Borrowers the aggregate amount of such Advance in accordance with the further terms of this Section 2.02. The failure or refusal of any Bank to make available to the Agent, at the aforesaid time
and place on any date of an Advance, the amount of its portion of the requested Advance shall not relieve any other Bank from its several obligation hereunder to make available to the Agent the amount of such other Bank’s portion of any
requested Advance. 
  
 The Agent may, unless notified to the contrary by any
Bank prior to the date of an Advance, assume that each Bank has made available to the Agent on such date of the applicable Advance the amount of each Bank’s portion of the Advance to be made on such date, and the Agent shall, in reliance upon
such assumption, make available to Borrowers a corresponding amount. If any Bank makes available to the Agent such amount on a date after the date of the applicable Advance, such Bank shall pay to the Agent on demand an amount equal to the product
of (i) the average computed for the period referred to in the numerator in clause (iii) below, of the weighted average interest rate paid by the Agent for federal funds acquired by the Agent during each day included in such period, times (ii)
the amount of such Bank’s portion of such Advance, times (iii) a fraction, the numerator of which is the number of days that elapse from and including such date of the Advance to the date on which the amount of such Bank’s portion
of such Advance shall become immediately available to the Agent, and the denominator of which is 365; provided, that if such Bank has not paid to the Agent such Bank’s portion of the Advance by 12:00 noon (central time) on the third
(3rd) Business Day after the Advance was made to Borrowers, then the interest rate in clause (i) above shall be the Prime Rate (adjusted daily) from and after such 2nd Business Day after the Advance was made until and including the date such Bank
makes available to the Agent such Bank’s portion of the Advance; provided, further, that if such Bank has not paid to the Agent such Bank’s portion of the Advance by 12:00 noon (central time) on the fifteenth (15th) Business
Day after the Advance was made to Borrowers, then the interest rate in clause (i) above shall be the Prime Rate (adjusted daily) plus three (3.0%) percent per annum from and after such 15th Business Day after the Advance was made until and including
the date such Bank makes available to the Agent such Bank’s portion of the Advance. A statement of the Agent submitted to each Bank with respect to any amounts owing under this paragraph shall be prima facie evidence of the amount
due and owing to the Agent by such Bank. If any Bank fails to pay to Agent its portion of any Advance within thirty (30) days after an Advance or if any Bank twice fails to timely make its portion of Advances to be made to Borrowers available to the
Agent before 12:00 noon (central time) on the dates Advances are made to Borrowers, then, if requested to do so by Borrower or any other Bank or the Agent, such Bank shall sell all of its interests, rights and obligations under this Agreement
(including all of its Commitment and its portion of the Credit Loan at the time owing to it) and the Note held by it to another Bank or bank under Section 9.06 hereof. 
  
 Absent manifest error, the credit advice resulting from the deposit of the proceeds of the Advance in Borrowers’ account with the
Agent shall be deemed conclusive evidence of Borrowers’ solidary (joint and several) indebtedness to the Banks in connection with the Credit Loan. 
  
 When each Advance is made by the Agent to a Borrower hereunder, Borrowers shall be deemed to have renewed and reissued each Credit Note for the amount of such
Advance represented by said 
  

 15 








 Credit Note plus the amount of all previous Advances then outstanding and all other amounts due under each Credit Note. 

 
 Section 2.03 Interest on the Credit Loan. (a) The Credit Loan shall bear
interest from the date of each Advance until paid at either (i) the Prime Rate plus the Applicable Margin, per annum, adjusted daily, or (ii) the Floating Rate plus the Applicable Margin, per annum, adjusted on the first day of each Interest Period
(i.e., in accordance with the definition of LIBO Rate, determined two (2) Business Days prior to each Interest Period). Interest on the Credit Loan shall be payable in arrears (x) if accruing based on the Prime Rate interest option, on the last day
of each month beginning February 29, 2004 and, with respect to any of the Credit Loan being converted to accrue interest based on the Floating Rate interest option, on the date of such conversion with respect to such portion being converted, (y) if
accruing based on the Floating Rate interest option, on the last day of each applicable Interest Period (unless an Interest Period is for 180 days, in which case interest on such applicable Advances shall be payable on the 90th day of such Interest
Period and on the last day of such Interest Period), and (z) on the maturity of the Credit Loan on the Maturity Date. All payments of interest shall be computed on the per annum basis of a year of 360 days for the actual number of days (including
the first day but excluding the last day) elapsed. 
  
 (b)
The Prime Rate shall remain fixed for one Business Day, to be adjusted daily. The Floating Rate shall remain fixed for the duration of any Interest Period for which the Floating Rate interest option is selected. Borrowers shall provide to the Agent
at least two (2) Business Days’ prior written notice of the change of interest accrual on any portion of the Credit Loan from the Prime Rate interest option to the Floating Rate interest option. At least two (2) Business Days prior to the end
of an Interest Period, Borrowers shall provide the Agent with written notice as to whether the applicable portion of the Credit Loan is to continue accruing interest at the Floating Rate interest option (and if so, then for what new Interest Period)
or to accrue at the Prime Rate interest option after the end of the Interest Period until further notice to the contrary from Borrowers. If Borrowers do not timely notify the Agent of their election for any portion of the Credit Loan accruing
interest at the Floating Rate interest option (i.e., at least two (2) Business Days prior to the end of an Interest Period), then the interest rate on such portion of the Credit Loan shall, following the end of such Interest Period, accrue interest
based on the Prime Rate interest option. 
  
 (c) Borrowers
will indemnify the Banks against, and reimburse the Agent (for payment to the Banks) on demand for, any loss or expense actually and demonstrably incurred or sustained by the Banks (including without limitation, any loss or expense incurred by
reason of the liquidation or reemployment of deposits or other funds acquired by the Banks to fund or maintain Floating Rate advances) as a result of any payment or prepayment (whether authorized or required hereunder or otherwise) of all or a
portion of any Floating Rate advance on a day other than the day on which the applicable Interest Period ends. For purposes of this Section, funding losses arising by reason of liquidation or reemployment of deposits or other funds acquired by the
Banks to fund or maintain Floating Rate advances shall be calculated as the remainder obtained by subtracting: (1) the yield (reflecting both stated interest rate and discount, if any) to maturity of obligations of the United States Treasury as
determined by the Agent in an amount equal or comparable to such advance for the period of time commencing on the date of the payment, prepayment or change of rate as provided above and ending on the last day of the subject interest period, from (2)
the Floating Rate of the subject Interest Period, times the number of days from the date of payment, prepayment or change of rate to the last day of the subject interest period, divided by 360. Any payment due under this Section will be paid
to the Agent within five days after demand therefor by the Agent, and if not timely received by the Agent, such amount shall thereafter accrue interest at the Default Rate and be payable on demand. 
  
 (d) The determination by the Agent of an interest rate hereunder or
interest amount due hereunder shall for all purposes be prima facie evidence of the correctness of such rate or calculation. 
  

 16 








 (e) At no time shall there be more than five (5) separate portions of the Credit Loan accruing
interest based on the Floating Rate interest option, and no portion of the Credit Loan accruing interest based on the Floating Rate interest option shall be for a principal amount of less than $1,000,000.00. 
  
 Section 2.04 Default Rate. If an Event of Default shall occur in the payment on
the due date of any payment of principal or interest due hereunder, Borrowers will pay interest on any such past due installment (retroactively) from the date of the Default on such payment up to the date of actual payment (as well after as before
judgment) at the Default Rate. Upon the acceleration of the principal indebtedness represented by the Credit Notes resulting from an Event of Default hereunder, the accelerated principal balance of the Credit Loan shall bear interest from the date
of acceleration up to the date of actual payment (as well after as before judgment) at the Default Rate. All such interest at the Default Rate shall be payable on demand. 
  
 Section 2.05 Prepayments. The Credit Loan shall or may be prepaid as follows: 
  
 (i) Mandatory Prepayments— 
  
 (y) The Required Banks shall be entitled to require mandatory
prepayments of the Credit Loan as set forth in Section 5.08 of this Agreement, unless other Collateral satisfactory to the Required Banks is substituted for the Collateral subject thereto, pursuant to documentation in form and substance satisfactory
to the Agent. 
  
 (z) Borrowers shall prepay the Credit
Loan from time to time as may be necessary so that the principal amount of the Credit Line outstanding does not exceed the Credit Limit then in effect. 
  
 (ii) Voluntary Prepayments—Borrowers may make voluntary prepayments from time to time on the Credit Loan outstanding hereunder, in whole or in
part, without premium or penalty (other than as provided in subsection 2.03(c) above and as otherwise may have been or be agreed to), upon at least two (2) Business Days’ notice to the Agent setting forth (x) the proposed date of prepayment
(which shall be a Business Day), and (y) the principal amount of the prepayment (which shall be an amount equal to at least one hundred thousand dollars ($100,000.00) or any lesser remaining balance of the Credit Loan then outstanding). 

 
 (iii) As to any prepayment, whether mandatory or voluntary, (y)
Borrowers shall pay all accrued interest on the portions of the Credit Loan so prepaid, at the time of prepayment, and (z) prepayments shall be applied first, to that portion of the Credit Loan accruing interest based on the Prime Rate interest
option and, second, to the remaining amounts of the Credit Loan outstanding with due regard, to the extent practicable, to minimizing any fees under subsection 2.03(c). 
  
 Section 2.06 Business Days. If the date for any payment or prepayment hereunder falls on a day which is not a Business Day,
then for all purposes of this Agreement (unless otherwise provided herein) the same shall be deemed to have fallen on the next following Business Day, and such extension of time shall in such case be included in the computation of payments of
interest. 
  
 Section 2.07 Nature of Commitment. The Banks’
obligation to make any Advance shall be deemed to be a transaction made pursuant to a contract to make a loan or extend debt financing or 
  

 17 








 financial accommodations to Borrowers within the meaning of Sections 365(c)(2) and 365(e)(2)(B) of the Bankruptcy Code of the
United States. 
  
 Section 2.08 Payments. Borrowers shall make each
payment hereunder and under the Notes and any other Loan Document in lawful money of the United States of America in same day funds to the Agent at its main office in New Orleans, Louisiana, not later than 11:00 a.m. (Central Time) on the day when
due, or such other place in the United States as designated in writing by the Agent. The Agent shall promptly send to each Bank by federal wire transfer its respective proportionate share of all amounts to which the Banks are entitled. 

 
 Section 2.09 Certain Fees. (a) Borrowers shall pay to the Agent (i) on the
Effective Date, for disbursement in accordance with subsection 9.01(a) hereof to the Banks pro-rata according to their Credit Commitments, a nonrefundable loan origination fee equal to $250,000, and (ii) after the Effective Date, simultaneously with
any increase in the Borrowing Base, for disbursement in accordance with subsection 9.01(a) hereof to the Banks pro-rata according to the respective increases in their respective Credit Commitments, a nonrefundable loan origination fee equal to a
percentage of the amount of the increase of the Borrowing Base, determined as follows: 
  

			
	 If the date of increase of the
 Borrowing Base occurs
between:

	  	 then the percentage applied shall be:


	 Effective Date—

	  	0.50%
	 February 14, 2005—

	  	0.10%

  
 (b) Borrowers
shall pay to the Agent, for disbursement in accordance with subsection 9.01(a) hereof to the Banks pro-rata according to their Credit Commitments, not later than the fifth (5th) Business Day after the end of each fiscal quarter, an Unused Commitment
Fee in arrears for the prior quarter. On the Maturity Date, Borrowers shall pay to the Agent, for disbursement in accordance with Article 9 hereof to the Banks pro-rata according to their Credit Commitments, an Unused Commitment Fee in arrears for
the period from the first day of the fiscal quarter in which the Maturity Date occurs up to, but not including, the Maturity Date. 
  
 (c) Borrowers shall pay to the Agent, for its own account, such fees as are agreed to in a separate agreement among Borrowers and the Agent with
respect to the Agent’s services provided hereunder and in connection herewith. 
  

 18 








 Section 2.10 Use of Proceeds. Borrowers shall use the proceeds of the Advances exclusively for their working
capital purposes and for funding, subject to the terms and conditions hereof, acquisitions of assets and companies and construction of vessels. 
  
 Section 2.11 Inability to Determine Floating Rate. In the event, prior to the commencement of any Interest Period relating to any portion of the Credit Loan
to accrue interest based on the Floating Rate interest option, the Agent shall determine or be notified by the Required Banks that adequate and reasonable methods do not exist for ascertaining the Floating Rate that would otherwise determine the
rate of interest to be applicable to any portion of the Credit Loan to accrue interest based on the Floating Rate interest option during any Interest Period, the Agent shall forthwith give notice of such determination (which shall be conclusive and
binding on Borrowers and the Banks absent manifest error) to Borrowers and the Banks. In such event (i) the applicable request giving rise to such determination, (x) if a request for an Advance, shall be deemed to have requested that the Advance
accrue interest based on the Prime Rate interest option, and (y) if a request to convert to, or continue, interest accrual based on the Floating Rate interest option, shall be denied and that portion of the Credit Loan shall accrue interest based on
the Prime Rate interest option, (ii) each portion of the Credit Loan then accruing interest based on the Floating Rate interest option will automatically, on the last day of the then current Interest Period thereof, convert to accrue interest based
on the Prime Rate interest option, and (iii) no further Advances shall be made that are to accrue interest based on the Floating Rate interest option until the Agent or the Required Banks determines that the circumstances giving rise to such
suspension no longer exist, whereupon the Agent or, as the case may be, the Agent upon the instruction of the Required Banks, shall so notify Borrowers and the Banks. 
  
 Section 2.12 Illegality. Notwithstanding any other provisions herein, if any present or future law, regulation, treaty or
directive or the interpretation or application thereof shall, subsequent to the date hereof, make it unlawful for any Bank to make any Advance or maintain any portion of the Credit Loan, in either case with interest accruing based on the Floating
Rate interest option, such Bank shall forthwith give notice of such circumstances to Borrowers and the other Banks and thereupon (a) the commitment of such Bank to make Advances accruing interest based on the Floating Rate interest option or to
convert portions of the Credit Loan so as to accrue interest based on the Floating Rate interest option shall forthwith be suspended and (b) such Bank’s portion of the Credit Loan then accruing interest based on the Floating Rate interest
option will automatically, on the last day of the then current respective Interest Periods thereof (unless required by law to be an earlier date), convert to accrue interest based on the Prime Rate interest option. Borrowers hereby agree promptly to
pay the Agent for the account of such Bank, upon demand by such Bank, any additional amounts necessary to compensate such Bank for any costs incurred by such Bank in making any conversion in accordance with this Section 2.12, including any interest
or fees payable by such Bank to lenders of funds obtained by it in order to make or maintain hereunder its portion of the Credit Loan accruing interest based on the Floating Rate interest option. 
  
 Section 2.13 Additional Costs, etc. If any present or future applicable law
relative to Floating Rate application, which expression, as used herein, includes statutes, rules and regulations thereunder and interpretations thereof by any competent court or by any governmental or other regulatory body or official charged with
the administration or the interpretation thereof and requests, directives, instructions and notices at any time or from time to time hereafter made upon or otherwise issued to any Bank or the Agent by any central bank or other fiscal, monetary or
other authority (whether or not having the force of law), shall: 
  
 (a) subject any Bank or the Agent to any tax, levy, impost, duty, charge, fee, deduction or withholding of any nature with respect to this Agreement, the other Loan Documents, such Bank’s Commitment or the Credit Loan (other than taxes
based upon or measured by the revenue, income or profits of such Bank or the Agent), or 
  

 19 








 (b) materially change the basis of taxation (except for changes in taxes on revenue, income or
profits) of payments to any Bank of the principal of or the interest on the Credit Loan or any other amounts payable to any Bank or the Agent under this Agreement or the other Loan Documents, or 
  
 (c) impose or increase or render applicable (other than to the extent
specifically provided for elsewhere in this Agreement) any special deposit, reserve, assessment, liquidity, capital adequacy or other similar requirements (whether or not having the force of law) against assets held by, or deposits in or for the
account of, or loans by, or commitments of an office of any Bank, or 
  
 (d) impose on any Bank or the Agent any other conditions or requirements with respect to this Agreement, the other Loan Documents, the Credit Loan, such Bank’s Commitment, or any class of loans or commitments of which the
Credit Loan or such Bank’s Commitment form a part, 
  
 and the result of any of the
foregoing is: 
  
 (i) to increase the cost to any Bank of
making, funding, issuing, renewing, extending or maintaining the Credit Loan or the Commitment of such Bank, or 
  
 (ii) to reduce the amount of principal, interest or other amount payable to such Bank or the Agent hereunder on account of the Commitment of such
Bank or the Credit Loan, or 
  
 (iii) to require such Bank
or the Agent to make any payment or to forego any interest or other sum payable hereunder, the amount of which payment or foregone interest or other sum is calculated by reference to the gross amount of any sum receivable or deemed received by such
Bank or the Agent from Borrowers hereunder, 
  
 then, and in each such case, Borrowers will,
upon demand made by such Bank or the Agent (as the case may be) at any time and from time to time and as often as the occasion therefor may arise, pay to such Bank or the Agent such additional amounts as will be sufficient to compensate such Bank or
the Agent for such additional cost, reduction, payment or foregone interest or other sum. 
  
 Section 2.14 Capital Adequacy. If after the date hereof any Bank determines that (i) the adoption of or change in any law, governmental rule, regulations, policy, guideline or directive (whether or not having the force
of law) regarding capital requirements for banks or bank holding companies or any change in the interpretation or application thereof by a court or governmental authority with appropriate jurisdiction, or (ii) compliance by such Bank or any
corporation controlling such Bank with any law, governmental rule, regulation, policy, guideline or directive (whether or not having the force of law) of any such entity regarding capital adequacy, has the effect of reducing the return on such
Bank’s commitment or portion of the Credit Loan to a level below that which such Bank could have achieved but for such adoption, change or compliance (taking into consideration such Bank’s then existing policies with respect to capital
adequacy and assuming full utilization of such entity’s capital) by any amount deemed by such Bank to be material, then such Bank may notify Borrowers of such fact. To the extent that the amount of such reduction in the return on capital is not
reflected in the Prime Rate, Borrowers agree to pay such Bank for the amount of such reduction in the return on capital as and when such 
  

 20 








 reduction is determined upon presentation by such Bank of a certification in accordance with Section 2.15 hereof. Each Bank shall
allocate such cost increases among its customers in good faith and on an equitable basis. 
  
 Section 2.15 Certificate. A certificate setting forth any additional amounts payable pursuant to Section 2.13 or 2.14 and a complete explanation of such amounts which are due, submitted by any Bank or the Agent to
Borrowers, shall for all purposes be prima facie evidence that such amounts are due and owing. 
  
 Section 2.16 Indemnity. Borrowers agree to indemnify each Bank and to hold each Bank harmless from and against any loss, cost or expense that such Bank may
sustain or incur as a consequence of (i) default by Borrowers in payment of the principal amount of or any interest on any portion of the Credit Loan accruing interest based on the Floating Rate interest option as and when due and payable, including
any such loss or expense arising from interest or fees payable by such Bank to lenders of funds obtained by it in order to maintain its portion of the Credit Loan accruing interest based on such Floating Rate interest option or (ii) default by
Borrowers in making a borrowing after Borrowers have provided a Draw Request Certificate requesting that the Advance to be made accrue interest based on the Floating Rate interest option. 
  
 Section 2.17 Application of Payments. Payments made under this Agreement and the other Loan Documents, whether made when due
under the Loan Documents or after foreclosure on Collateral, for application to the Obligations shall be applied to the Obligations as follows: 
  
 (i) to the Agent, with respect to fees and expenses accrued and outstanding (including without limitation reasonable attorneys’ fees and
expenses); 
  
 (ii) to the Banks, ratably according to
their Credit Commitments, with respect to fees under Section 2.09 hereof; 
  
         (iii) to the Banks, with respect to other fees and expenses and late charges accrued and outstanding with respect to the Obligations (including without limitation reasonable attorneys’
fees and expenses of the Banks in accordance with Section 5.07 hereof), “pro-rata according to the respective loan amounts then outstanding” (hereinafter defined). Of the fees and expenses and late charges due with respect to the Credit
Loan (as opposed to Hedging Obligations), such amounts shall then be paid to the Banks ratably according to the Banks’ applicable Commitments; 
  
 (iv) to the Banks, with respect to interest accrued and outstanding on the Obligations, “pro-rata according to the respective loan amounts then
outstanding”. Of the interest accrued and then outstanding with respect to the Credit Loan (as opposed to Hedging Obligations), such amounts shall then be paid to the Banks ratably according to the Banks’ applicable Commitments; and

  
 (v) to the Banks, with respect to principal amounts of
the Credit Loan due and payable and Hedging Obligations then due and unpaid, “pro-rata according to the respective loan amounts then outstanding”. Of the principal due with respect to the Credit Loan (as opposed to the Hedging
Obligations), such amounts shall then be paid to the Banks ratably according to the Banks’ applicable Commitments. 
  
 “Pro-rata according to the respective loan amounts then outstanding” shall be determined— 
  

 21 








 (i) in instances other than with respect to foreclosure on Collateral or the exercise by the Agent of its other
rights and remedies under the Loan Documents, applicable amounts under a subsection as to Hedging Obligations shall not be considered, and 
  
 (ii) in instances with respect to foreclosure on Collateral or the exercise by the Agent of its other rights and remedies under the Loan Documents, by adding the
aggregate principal amounts of the Credit Loan outstanding and Hedging Obligations then due and unpaid before giving effect to the payment and then dividing that sum by the Credit Loan amount outstanding and the Hedging Obligations due and unpaid to
determine the Credit Loan’s and Hedging Obligations’ respective percentages of application; following such allocation to Hedging Obligations, the Bank holding such Hedging Obligations shall be entitled to the amount so allocated for
application against the relevant Hedging Obligations.

performing its obligations under the Loan Documents. Except as otherwise disclosed to the Agent and the Banks in writing, no event has occurred (including, without limitation, any litigation or administrative proceedings) and no condition exists or,
to the knowledge of either Borrower, is threatened, which (i) might render 
  

 25

would constitute a Default hereunder, or (iii) might materially adversely affect the financial condition of either Borrower or the validity or priority of the lien of the Collateral Documents to which either Borrower is a party.

in, advances to or guaranties of the obligations of any Person, except as reflected in the financial statements described in Section 4.06 hereof, or as set forth on Schedule 4.07 attached hereto or as otherwise disclosed to the Agent and the
Banks in writing, or as expressly permitted by this Agreement.

against or affecting either Borrower which involves the possibility of any judgment or liability not fully covered by insurance (except for a deductible of up to $100,000), and which may materially and adversely affect, whether individually or in
the aggregate, the business or the property of either Borrower or either Borrower’s ability to carry on business as now conducted. 
  
 Section 4.09 Taxes and Governmental Charges. Each Borrower has filed all tax returns and reports required to be filed and has paid all taxes, assessments,

neither Borrower is engaged in the business of extending credit for the purpose of, purchasing or carrying any “margin stock” as defined in Regulation U of the Board of Governors of the Federal Reserve System (12 C.F.R. Part 221), or for
the purpose of reducing or retiring any indebtedness which was originally incurred to purchase or carry a margin stock or for any other purpose which might constitute this transaction a “purpose credit” within the meaning of said
Regulation U. Neither Borrower is engaged principally, or as one of such Borrower’s important activities, in the business of extending credit for the purpose of purchasing or carrying margin stocks. Neither either Borrower nor any other Person
acting on behalf of either Borrower has taken or will take any action

Borrowers agree to provide, or cause to be provided to, the Agent with originals or certified copies of such policies of insurance or certificates with respect thereto. Borrowers further agree to promptly furnish the Agent with copies of all renewal
notices and, if requested by the Agent, with copies of receipts for paid premiums. Borrowers shall provide, or cause to be provided to, the Agent binders or such other proof acceptable to the Agent that renewal or replacement policies of insurance
will be in effect before any such existing policy or policies should expire. If Borrowers’ insurance policies and renewals are held by another Person, Borrowers agree to supply, or cause to be supplied, original or certified copies of the same
to the Agent, together with binders or such other proof acceptable to the Agent that renewal or replacement policies of insurance will be in effect before any such existing policy or policies should expire. 
  
 (d) In the event Borrowers should, for any reason whatsoever, fail to
cause any insurance required hereunder or under the HOT Fleet Mortgage or the HOS Fleet Mortgage to be maintained as herein or therein provided, or to cause such policies to be and remain so assigned or payable as provided herein, or to cause to be
delivered to the Agent satisfactory evidence thereof, then the Agent, if it so elects, may itself have any such insurance effected in such amounts and in such companies as it may deem proper and may pay the premiums therefor and Borrowers shall
reimburse the Agent (and the Banks, if applicable) upon demand for the amount of the premiums paid, together with interest thereon at the Default Rate from date until paid. The Agent and the Banks shall not be responsible for the solvency of any
company issuing any insurance policy, whether or not selected or approved by the Agent or the Banks, or for the collection of any amounts due under any such policy, and shall be responsible and accountable only for such money as may be actually
received by the Agent or the Banks. 
  
 (e) Borrowers agree
to immediately notify the Agent in writing of any material casualty to or accident involving a HOT Vessel or a HOS Vessel (or any other vessel owned by either Borrower or any Guarantor Subsidiary that could have a material adverse effect upon such
Borrower or such Guarantor Subsidiary), in each case whether or not such casualty or loss is covered by insurance. Borrowers further agree to promptly notify the applicable Borrower’s insurance company and to submit 
  

 31 








 an appropriate claim and proof of claim to the insurance company in the event that a HOT Vessel or a HOS Vessel or
any other vessel owned by either Borrower, is lost, damaged, or destroyed as a result of an insured hazard. As to the HOT Vessels and the HOS Vessels, the Agent may submit such a claim and proof of claim to the insurance company on the applicable
Borrower’s behalf, should the applicable Borrower fail to do so promptly for any reason. As to the HOT Vessels and the HOS Vessels, each Borrower hereby irrevocably appoints the Agent as its agent and attorney-in-fact, each such agency being
coupled with an interest, to make, settle and adjust claims under such policy or policies of insurance (regardless of whether a settlement or adjustment of a claim is an Event of Default) and to endorse the name of such Borrower on any check or
other item of payment for the proceeds thereof; it being understood, however, that unless one or more Defaults exist under this Agreement, the Agent will not settle or adjust any such claim without the prior approval of such Borrower (which approval
shall not be unreasonably withheld). 
  
 (f) In the event
of an actual, constructive, agreed, compromised or arranged total loss or of any requisition of a HOT Vessel or a HOS Vessel, all insurance payments therefor shall be made payable, and delivered, only to the Agent and no other Person. Neither
Borrower shall declare or agree with underwriters that a HOT Vessel or a HOS Vessel is a constructive or compromised, agreed or arranged constructive total loss without the prior written consent of the Agent and the Required Banks. The proceeds of
all other insurance (i) covering a HOT Vessel shall be made payable to HOT and the Agent jointly, and delivered to the Agent, and (ii) covering a HOS Vessel shall be made payable to HOS and the Agent jointly, and delivered to the Agent. Subject to
the last sentence of this paragraph, the Agent shall make available to the applicable Borrower the proceeds of all insurance (x) by an appropriate payment order directed to the interested underwriter to pay any outstanding bill for repairing or
replacing a HOT Vessel or a HOS Vessel and/or any outstanding third-party claims or (y) to reimburse the applicable Borrower in whole or in part for any expenditures the applicable Borrower may have made for repairing or replacing a HOT Vessel or a
HOS Vessel and/or to pay any third party claims, but the Agent, as a condition precedent to such reimbursement, may require the applicable Borrower to furnish the Agent with receipted bills or waivers of liens or appropriate releases for any
third-party claims. In connection with any repair to or replacement of a HOT Vessel or a HOS Vessel, the applicable Borrower shall be required to pay the amount of the deductible and the applicable Borrower shall be required to pay any balance of
the cost of repairs or replacement not covered by insurance. Notwithstanding the foregoing provisions of this Section 5.08, but subject to clause (B) of the next sentence following this sentence, the insurance policies may provide that if for a
particular claim any such insurance payments do not exceed $125,000.00, then such payments may be paid to the applicable Borrower. Notwithstanding anything contained herein to the contrary, the Agent shall, at the option of the Required Banks, be
entitled to receive any insurance proceeds and apply them to the Obligations (in accordance with Section 2.17 hereof, and if there is then existing an Event of Default, then there shall be deemed to have been a foreclosure on Collateral for purposes
of Section 2.17) if (A) there has been an actual, constructive, agreed or arranged total loss or requisition of a HOS Vessel or a HOT Vessel or (B) there otherwise has been and is then continuing any Event of Default. 
  
 (g) The Agent’s receipt of such insurance proceeds and the
application of such proceeds as provided herein shall not, however, affect the Agent’s Liens against the HOT Vessels or the HOS Vessels, for the ratable benefit of the Banks. Other than the circumstances where insurance proceeds relative to the
loss of or damage to a HOT Vessel or a HOS Vessel are applied to the repayment of the Obligations, nothing under this Section shall be deemed to excuse Borrowers from their obligations to promptly repair, replace or restore any lost or damaged
vessel, whether or not the same are covered by insurance, whether or not such proceeds of insurance are available, and whether or not such proceeds are sufficient in amount to complete such repair, replacement or restoration, to the satisfaction of
the Agent. Furthermore, unless otherwise confirmed by the Agent and the Banks in writing, the application or release of any insurance proceeds by the Agent shall not be deemed to cure or waive any Event of Default under 
  

 32 








 this Agreement. Any proceeds which have not been disbursed within one (1) month after their receipt and which a
Borrower has not committed to the repair or restoration of a HOT Vessel or a HOS Vessel shall be used to repay the Credit Loan (in accordance with Section 2.17 hereof). 
  
 (h) Borrowers, upon request of the Agent, shall furnish, or cause to be furnished, to the Agent reports on each
existing policy of insurance showing such information as the Agent or the Required Banks may request, including without limitation the following: (i) the name of the insurer; (ii) the risks insured; (iii) the amount of the policy; (iv) the property
insured; (v) the then current value on the basis of which insurance has been obtained and the manner of determining that value; and (vi) the expiration date of the policy. 
  
 Section 5.09 Accounts and Records. Borrowers will keep, and will cause Guarantor to keep, books of record and accounts in which
true and correct entries will be made as to all material matters of all dealings or transactions in relation to the respective business and activities, sufficient to permit reporting in accordance with generally accepted accounting principles,
consistently applied. 
  
 Section 5.10 Right of Inspection. (a)
Borrowers will, and will cause Guarantor to, permit any officer, employee or agent of the Agent, any Bank, the Surveyor, the United States Coast Guard or the American Bureau of Shipping to visit and inspect the HOS Vessels and the HOT Vessels, and
to visit and inspect the other Collateral, and (b) Borrowers will, and will cause Guarantor to, permit any officer, employee or agent of the Agent and (upon the occurrence and continuance of an Event of Default) any Bank to examine the books of
record and accounts of Borrowers and Guarantor, take copies and extracts therefrom, and discuss the affairs, finances and accounts of Borrowers and Guarantor with Borrowers’ and Guarantor’s officers, accountants, counsel and auditors, all
of the foregoing at such reasonable times and on reasonable notice and without hindrance or delay and as often as the Agent, any Bank (if applicable), the Surveyor, the United States Coast Guard or the American Bureau of Shipping may reasonably
desire. 
  
 Section 5.11 Maintenance of Properties. Borrowers shall
maintain and preserve, and cause Guarantor to maintain and preserve, all of Borrowers’ and Guarantor’s respective properties (and any property leased by or consigned to a Borrower or Guarantor or held under title retention or conditional
sales contracts) that are used or useful in the conduct of Borrowers’ and Guarantor’s respective business in the ordinary course in good working order and condition at all times, ordinary wear and tear excepted, and make all repairs,
replacements, additions, betterments and improvements to its properties to the extent necessary so that any failure will not materially and adversely affect the business of a Borrower or Guarantor. Without limiting the generality of the foregoing,
Borrowers shall at all times maintain the Vessels in compliance with the requirements of the American Bureau of Shipping or any other classification society acceptable to the Agent, for the highest classification for vessels of like age and type,
and upon the Agent’s request therefor, the Borrowers shall promptly provide to the Agent copies of certificates duly issued by the American Bureau of Shipping or other classification society acceptable to the Agent, to the effect that the
Vessels have been given the highest classification and rating for vessels of the same respective ages and types, free of all recommendations and notations of such classification society affecting class. 
  
 Section 5.12 Notice of Certain Events. (a) Borrowers shall promptly notify the
Agent if either Borrower learns of the occurrence of any event which constitutes a Default, together with a detailed statement by a responsible officer of each Borrower as to the nature of the Default and the steps being taken to cure the effect of
such Default. 
  
 (b) Borrowers shall promptly notify the
Agent of any change in location of a Borrower’s principal place of business or the office of a Borrower where records concerning accounts and 
  

 33 








 contract rights are kept, or any change in the federal taxpayer identification number or organizational
identification number of a Borrower. 
  
 (c) Borrowers
shall promptly provide the Agent, upon request therefor by the Agent, listings of the Borrowers’ assets and the condition thereof, in form and substance satisfactory to the Agent. 
  
 (d) Borrowers shall promptly submit such information in form and substance satisfactory to the Agent as may be
reasonably requested by the Agent concerning construction of new vessels for the Borrowers. 
  
 (e) Borrowers shall promptly notify the Agent of any defaults or alleged defaults of any party with respect to any construction contract for
new-build vessels or any charter agreement that could have a material adverse effect upon either Borrower or any of their Affiliates, and thereafter keep the Agent advised of any significant developments in connection therewith. 
  
 (f) Borrowers shall promptly notify the Agent of any and all Liens
filed or otherwise asserted, and attachments made, against the HOS Vessels or the HOT Vessels, together with copies of all related instruments and any other materials that the Agent shall require. 
  
 (g) Borrowers shall cause Guarantor to provide to the Agent (i)
written notice of any sale or transfer of shares of five (5%) percent or more of the stock of Guarantor promptly after any such sale or transfer and (ii) upon request therefor by the Agent from time to time, evidence satisfactory to the Agent that
no Change in Control has occurred. 
  
 Section 5.13 Indemnity.
Borrowers hereby agree to defend, indemnify and hold the Agent and the Banks and their respective directors, officers, agents and employees harmless from and against all claims, demands, causes of action, liabilities, losses, costs and expenses
(including, without limitation, costs of suit, reasonable legal fees and fees of expert witnesses; provided, that such costs of suit, reasonable legal fees and fees of expert witnesses shall be only those incurred by the Agent;
provided, further, that such limitation in connection with the indemnity hereunder shall not limit the application of Section 5.07 hereof) arising from or in connection with (i) the presence in, on or under all Collateral and their
other properties of any Hazardous Material, or any releases or discharges thereof on, under or from such property, (ii) any activity carried on or undertaken on or off such property, whether prior to or during the term of this Agreement, and whether
by a Borrower, a contractor or any predecessor in title or any officers, employees, agents, contractors, or subcontractors of a Borrower, a contractor or any predecessor in title, or any third persons at any time occupying or present on such
property, in connection with the handling, use, generation, manufacture, treatment, removal, storage, decontamination, clean-up, transport or disposal of any such Hazardous Material at any time located or present on or under such property, (iii) any
and all other third party claims in connection with any of the Collateral or their other properties, or (iv) any breach of any representation, warranty or covenant under the terms of this Agreement. The foregoing indemnity shall further apply to any
residual contamination affecting any natural resources, and to any contamination of any property or natural resources arising in connection with the generation, use, handling, storage, transport or disposal of any such Hazardous Material, and
irrespective of whether any of such activities were or will be undertaken in accordance with applicable Governmental Regulations, and shall survive the termination of this Agreement and all of the other Loan Documents. The indemnity herein shall not
apply to the extent of any gross negligence or willful misconduct on the part of the Agent or the Banks. 
  
 Section 5.14 ERISA Information and Compliance. Borrowers will furnish to the Agent (i) promptly after the filing thereof with the United States Secretary of
Labor or the Pension Benefit Guaranty Corporation, copies of each annual and other report with respect to each Plan or any trust 
  

 34 








 created by either Borrower, and (ii) immediately upon becoming aware of the occurrence of any “reportable event,” as such
term is defined in Section 4043 of ERISA, or of any “prohibited transaction,” as such term is defined in Section 4975 of the Internal Revenue Code of 1986, as amended, in connection with any Plan or any trust created by either Borrower, a
written notice signed by the president, the chairman or the chief financial officer of each Borrower specifying the nature thereof, what action the applicable Borrower is taking or proposes to take with respect thereto, and, when known, any action
taken by the Internal Revenue Service with respect thereto. Each Borrower will comply with all of the applicable funding and other requirements of ERISA as such requirements relate to the Plans of such Borrower. 
  
 Section 5.15 Charters. HOS shall perform all of its obligations in respect of,
and observe all of the terms and provisions of, any charter of a HOS Vessel, and shall use its best efforts to keep all such agreements in full force and effect for the applicable term thereof. HOT shall perform all of its obligations in respect of,
and observe all of the terms and provisions of, any charter of a HOT Vessel, and shall use its best efforts to keep all such agreements in full force and effect for the applicable term thereof. Notwithstanding the foregoing, no breach by a Borrower
under a charter shall be a Default or Event of Default hereunder unless the result would have a material adverse effect on the financial condition of a Borrower or otherwise on a Borrower’s ability to repay the Obligations. 
  
 Section 5.16 Intentionally omitted. 
  
 Section 5.17 Collateral Value. The Borrowers shall cause the fair market value
of the Vessels (and other vessels of Guarantor Subsidiaries or (subject to the second sentence hereafter) other Subsidiaries of Guarantor included within the Collateral in accordance with subsections 3.01(h) and (i) hereof) at all times to be
greater than or equal to two hundred (200%) percent of the Borrowing Base from time to time in effect. If from time to time, in order for Borrowers to comply with the preceding sentence, additional vessels are required to be mortgaged to the Agent,
then (i) the Agent shall be entitled to choose in its sole and absolute discretion which additional vessel or vessels owned (subject to the next following sentence) by any Subsidiary of Guarantor, not otherwise subject to a mortgage Permitted Lien
(as to the Borrowers) or a mortgage Lien securing Debt that otherwise does not violate this Agreement (as to any other Subsidiary of Guarantor), shall be so mortgaged so that Borrowers will be in compliance with the preceding sentence (and the
parties acknowledge that the Borrowers may suggest what additional vessel or vessels they would prefer but such suggestions nevertheless shall not have the effect of impairing the fact that the selection is at the Agent’s sole and absolute
discretion), and (ii) the applicable Borrower(s) or Guarantor Subsidiary(ies) or other Subsidiary(ies) of Guarantor owning such vessel(s) shall promptly supplement and amend the applicable Collateral Documents and this Agreement, or enter into
Collateral Documents, pursuant to documentation in form and substance satisfactory to the Agent, so as to grant to the Agent, for the ratable benefit of the Banks, first preferred ship mortgage liens (or the foreign equivalent) thereon and first
priority security interests (or the foreign equivalent) in all related assets (see, subsections 3.01(a) - (d)), and in connection therewith Borrowers shall provide to the Agent evidence of insurance required under the Loan Documents and applicable
Certificates of Documentation as to the vessels and vessel abstracts thereon showing the HOS Mortgage or the HOT Mortgage (or other first preferred ship mortgage, if by a Guarantor Subsidiary or other Subsidiary), as the case may be, as the only
recorded Lien thereon. Notwithstanding the foregoing, to the extent necessary so that no Subsidiary formed outside the United States will be considered under the U.S. Internal Revenue Code (as amended) and the regulations promulgated thereunder
(including without limitation Reg. Section 1.956-2(c)(2)) to be a pledgor or guarantor of the Obligations, the Agent agrees that in choosing additional vessels to be Collateral, it will not choose vessels owned by a Subsidiary formed outside the
United States if the Borrowers, Guarantor Subsidiaries or other Subsidiaries formed within the United States own vessels that are not already Collateral and that are operating; provided, that the Borrowers acknowledge and agree that, without
limiting each Bank’s right to approve or disapprove increases in the Borrowing Base in its 
  

 35 








 sole discretion, any Bank’s dissatisfaction with the additional collateral taken as a whole may be a reason for withholding
its consent to an increase in the Borrowing Base. If the market value of the Vessels (and other vessels granted as Collateral) is greater than two hundred (200%) percent of the Borrowing Base, Borrowers shall not be entitled to the release of any
Collateral without the written consent of all Banks. Borrowers shall not substitute vessels (and related assets) for existing Vessels that are Collateral without the written consent of the Required Banks. The parties hereto acknowledge and consent
that on the Effective Date, the HOS GEMSTONE (Official Number 1141952) is being substituted for the HOS CORNERSTONE (Official Number 1091051) as a HOS Vessel. 
  

Section 5.18 Appraisal. The Required Banks shall be entitled to require, at any time (but in any event only two (2) times during the term of this
Agreement) that Agent obtain appraisals by the Surveyor relative to the Vessels. The foregoing limitation shall not apply (i) in connection with increases of the Borrowing Base and (ii) during the occurrence and continuance of any Default or Event
of Default, in which event the Agent or the Required Banks shall be entitled to require by the Surveyor other appraisals relative to the Vessels. Borrowers shall, in accordance with Section 5.07 hereof, be liable for all expenses in connection with
any such appraisals. In addition to the foregoing, the Required Banks may from time to time in their discretion obtain further appraisals by the Surveyor relative to the Vessels, at the pro-rata cost and expense of all the Banks (computed by
reference to each Bank’s respective Commitments). 
  
 Section 5.19
Deposit Accounts. Borrowers shall (and Borrowers shall cause Guarantor to) maintain their primary domestic deposit, collection and disbursement banking accounts at the Agent. The foregoing is not applicable to investment or foreign banking
accounts of Borrowers and Guarantor or other banking related products.

 (v) Precautionary Liens on property covered by capital leases; 
  
 (vi) Legal or equitable encumbrances deemed to exist by reason of
negative pledge covenants and other covenants or undertakings of like nature (provided, that any such covenant or undertaking shall not apply to Borrowers’ ability to grant Liens in favor of the Agent and the Banks); 
  
 (vii) Purchase money Liens granted by a Borrower on equipment
(including vessels) of such Borrower that is not Collateral, securing the purchase price of such equipment; provided, that such Lien shall not extend to or cover any other property of either Borrower or Guarantor;

on the Effective Date or other vessels acquired or constructed by a Borrower after July 19, 2001, securing Debt incurred by a Borrower for the acquisition of assets or construction of vessels by a Borrower after the Effective Date or securing
refinances of such Debt (but not principal amounts over and above the principal amount(s) refinanced; and 
  
 (ix) Liens on property of a Borrower that is not Collateral, which Liens arise from a judgment or judgments against a Borrower; provided,

(i) Borrowers shall be permitted to make cash distributions, collectively, to Guarantor (x) that are simultaneously invested as equity in the other Borrower or a Subsidiary Guarantor, and (y) otherwise, of up to $2,000,000 in any calendar year in
the aggregate for both Borrowers collectively, but in any such event under clause (x) or (y), only if there is no Default or Event of Default and the making of any such dividend shall not give rise to a Default or an Event of Default, and (ii) stock
dividends (including any rights distributed pursuant to a stockholder rights plan), stock splits and reverse stock splits with respect to Guarantor shall be permitted; provided, further, that Borrowers shall promptly notify the Agent
(or cause the Guarantor to notify the Agent) of any such permitted dividends, splits or reverse splits.

logistics services related thereto.

assess the proposed action and, further, if the Agent and the Required Banks so consent, then Guarantor and Borrowers and such other Persons as may be required by the Agent shall execute and deliver such documents as the Agent requires, in form and
substance satisfactory to the Agent. 
  
 Section 6.06 ERISA
Compliance. Neither Borrower will at any time permit any Plan maintained by it to engage in any “prohibited transaction” as such term is defined in Section 4975 of the Code; incur any “accumulated funding deficiency” as such
term is defined in Section 302 of ERISA; or terminate any such Plan in a manner which could result in the imposition of a Lien on the property of such Borrower pursuant to Section 4068 of ERISA. 
  
 Section 6.07 Indenture Documents. Borrowers shall not amend, modify, supplement,
refinance or waive (and Borrowers shall cause Guarantor to not amend, modify, supplement, refinance or waive) the Indenture Documents, or enter into other documents in connection therewith (and Borrowers shall cause Guarantor to not enter into other
documents in connection therewith), including without limitation as to any refinance, to increase the interest rates or fees or premiums thereunder, to add any additional collateral thereunder, to increase or decrease the principal amount subject
thereto if the incurrence of the Debt will result in a Default or an Event of Default, to add other circumstances that would require 
  

 40 








 prepayment of the underlying loans, to change any sections containing provisions relating to insurance requirements or the
applications of insurance proceeds or other insurance-related matters, to change any sections containing provisions relating to asset sales, to change Section 4.09 thereof, to reduce any standstill periods, to place further restrictions on the
ability of Borrowers or Guarantor to operate or conduct their business, to add any other defaults or events of default (or amend the definitions thereof in a manner that would be more restrictive on Borrowers, Guarantor, or any Subsidiaries), or to
change the maturity, amortization and other payment schedules of the underlying loans. In addition, Borrowers shall not otherwise amend, modify, supplement, refinance or waive (and Borrowers shall cause Guarantor not to amend, modify, supplement,
refinance or waive) the Indenture Documents in any manner so as to make any of the covenants therein more restrictive than when first executed or so as to result in a Default or Event of Default or provide for Borrower or the Guarantor to take or
not take any action that could result in a Default or Event of Default. As to all other amendments, modifications, supplements, refinances and waivers to such documents, Borrowers shall provide to the Agent an executed copy promptly after the
execution and delivery thereof. As of the Effective Date, the Banks and the Agent (i) understand that the Guarantor intends to amend or refinance the Indenture Obligations during the term of this Agreement, and (ii) acknowledge that if (x) the
amended or refinanced Debt thereunder accrues interest at a rate per annum less than the per annum interest rate that the notes issued under the Indenture accrue on the Effective Date, (y) the amended or refinanced Debt thereunder is scheduled to
mature later than the scheduled maturity of the notes issued under the Indenture in existence on the Effective Date, and (z) the debt incurrence covenants under the amended or refinanced Indenture are less stringent on the Guarantor than the debt
incurrence covenants under Section 4.09 of the Indenture as in existence on the Effective Date, then such provisions shall not violate this Section 6.07; provided, that nothing in this sentence shall be construed as limiting the possible
acceleration of the Maturity Date as set forth in the definition of such term in Section 1.02 hereof or as amending or otherwise modifying the debt incurrence provisions under this Agreement. 
  
 Section 6.08 Indenture Obligations and Other Debt Payments and Prepayments.
Borrowers shall not pay (or allow same by an other Person) the Indenture Obligations or any other Debt (other than the Obligations and trade payables coming due in the ordinary course of business) incurred after December 31, 2001 if there is then
existing a Default or an Event of Default or if doing so would give rise to a Default or an Event of Default. Borrowers shall not prepay (or allow same by any other Person) any Debt, other than (i) the Credit Loan, in accordance with this Agreement,
(ii) trade payables, in the ordinary course of business, and (iii) as to all other Debt (including without limitation the Indenture Obligations), so long as there is no Default or Event of Default then existing and doing so would not give rise to a
Default or an Event of Default and the Borrowers shall have $10,000,000 in cash or cash equivalents in account(s) maintained at one or more Banks or otherwise available for the making of Advances under the Credit Line (taking into account the Credit
Limit), partial prepayments of such other Debt or the refinancing of any such other Debt in full. If any Debt is to be incurred by the Borrowers or the Guarantor for any prepayments, reference is hereby made to Section 10.12 hereof as to certain
conditions that may have to be satisfied before the incurrence of such Debt. 
  
 Section 6.09 Loans. Borrowers, Guarantor Subsidiaries and Guarantor shall not lend or advance any money to any Person; provided, that (i) intra-company Debt, in an aggregate amount not to exceed $20,000,000 outstanding at any
one time, owed by Guarantor, a Borrower, a Subsidiary or a less than 50%-owned Affiliate of a Borrower, Guarantor or a Guarantor Subsidiary to a Borrower, a Guarantor Subsidiary or Guarantor in connection with accounting allocations between such
Persons (provided, further, that such Debt shall be unsecured and subordinated to the Obligations upon terms and conditions satisfactory to Agent) is permitted, (ii) loans or advances by Guarantor, a Borrower, or a Guarantor Subsidiary
to Guarantor, a Borrower or a Guarantor Subsidiary (provided, further, that such Debt shall be unsecured and subordinated to the Obligations upon terms and conditions satisfactory to Agent) are permitted, (iii) loans or advances to

 made in the ordinary course of business and consistent with past practices of the Borrowers, Guarantor Subsidiaries, and the
Guarantor in an aggregate amount not to exceed $500,000 outstanding at any one time, are permitted, and (iv) Guarantor, a Borrower or a Guarantor Subsidiary may provide financing to a Person in connection with such Person acquiring an ownership
interest in a Subsidiary or a less than 50%-owned Affiliate of a Borrower, Guarantor or a Guarantor Subsidiary (and such financing shall be for no other purpose) where such Person’s ownership interest is reasonably necessary, advisable or
incidental to the conduct of business by such Subsidiary or Affiliate in a jurisdiction outside of the United States (provided, further, that (x) as to such a financing provided by a Guarantor Subsidiary that does not involve a
transfer of equity in such Guarantor Subsidiary and as to any such financing provided by a Borrower or Guarantor, the Person acquiring the equity interest shall be acquiring it from the applicable Loan Party providing the financing, (y) no actual
funds shall transfer from the Guarantor, a Borrower or a Guarantor Subsidiary in connection with any such financing and (z) no such financings in the aggregate shall be with respect to more than thirty percent (30%) of the equity of any such

than $5,000,000, then such Bank may sell all of its Commitment), (v) the parties to such assignment have executed and delivered to the Agent an Assignment and Acceptance, substantially in the form of Exhibit C hereto (the “Assignment
and Acceptance”), together with the Note subject to such assignment, one or more signature pages to this Agreement containing the 
  

 50 








 signature of the assignee, and (following the Effective Date, as defined in the applicable Assignment and
Acceptance) payment by the assignee to the Agent for its own account of an assignment administration fee in the amount of $3,500.00, (vi) either the assignor or assignee shall have paid the Agent’s and any Bank’s costs and expenses
(including without limitation attorneys fees and expenses) in connection with the assignment if, in accordance with Section 5.07 hereof, such costs and expenses are not to be borne by Borrowers, (vii) the Agent shall have delivered to the Borrowers
a fully executed copy of such Assignment and Acceptance, and (viii) the assignee is (A) a state or national commercial bank or other financial institution located in the United States or (B) a bank or other financial institution organized under a
jurisdiction other than the United States, provided that such foreign bank or other financial institution has provided the Agent and the Borrowers with forms prescribed by the Internal Revenue Service certifying as to such Bank’s status for
purposes of determining exemption from United States withholding taxes with respect to all payments to be made to such Bank hereunder, and provided further that such foreign bank or other financial institution shall not transfer its interests,
rights and obligations under this Agreement to any affiliate of such foreign bank or other financial institution unless such affiliate provides the Agent and the Borrowers with the aforesaid tax forms; provided, that with respect to clause
(ii) above, the Borrowers’ consent also shall not be required as to an assignment by a Bank of all of its Commitment if such assignment is part of a sale or assignment of all or substantially all of either that Bank’s assets or its marine
transactions portfolio and the acquiring Person is a bank or financial institution not affiliated with any company engaged in marine transportation and is not a creditor of the Borrowers or the Guarantor with respect to other Debts. Upon
satisfaction of each of the foregoing conditions and upon acceptance and notation by the Agent, from and after the effective date specified in each Assignment and Acceptance, which effective date shall be at least five (5) Business Days after the
execution thereof, (x) the assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Bank, and (y) the assigning Bank shall, to the extent provided in such
assignment, be released from its obligations under this Agreement. Notwithstanding the foregoing, the restrictions contained above in this subsection 9.06(a) shall not apply to assignments to any Federal Reserve Bank, and the conditions set forth in
clauses (i) and (ii) above shall not apply to assignments by any Bank to any Person which controls, is controlled by, or is under common control with, or is otherwise substantially affiliated with that Bank. 
  
 (b) Upon its receipt of an Assignment and Acceptance executed by the
parties to such assignment together with the Note subject to such assignment and the written consent of the Agent and the Borrowers to such assignment, the Agent shall give prompt notice thereof to the Borrowers and the Banks. Within five (5)
Business Days after receipt of such notice, the Borrowers at their own expense, shall execute and deliver to the Agent, in exchange for the surrendered Note, a new Note to the order of such assignee(s) in an amount equal to the amount assumed by
such assignee pursuant to such Assignment and Acceptance and, if the assigning Bank has retained some portion of its obligations hereunder, a new Note to the order of the assigning Bank in an amount equal to the amount retained by it hereunder. Such
new Notes shall be in an aggregate principal amount equal to the aggregate principal amounts of the surrendered Note, shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in the form of the assigned Note. The
surrendered Note shall be canceled and returned to the Borrowers. The Agent shall have the right to substitute a revised Schedule 1 hereto to reflect the respective Commitments (and Borrowing Base Credit Commitments) following each such
assignment. 
  
 (c) Each Bank, without the consent of the
Agent, the other Banks or the Borrowers, may sell participations to one or more banks or other financial institutions not affiliated with any company engaged in marine transportation and not a creditor of the Borrowers or the Guarantor with respect
to other Debts (and such bank or banks or financial institution or financial institutions shall be bound by the terms of this Agreement, including without limitation this Section 9.06) in all or a portion of the Credit Loan (including its
Commitment) under this Agreement; provided, that the selling Bank shall 
  

 51 








 retain the sole right and responsibility to enforce the obligations of the Borrowers relating to the Credit Loan
and that the only rights granted to the participant pursuant to such participation arrangements with respect to waivers, amendments or modifications of this Agreement shall be the right to approve waivers, amendments, or modifications which require
the consent of all of the Banks as provided in Section 10.12 hereof. 
  
 Section 9.07 Indemnification of the Agent. The Banks ratably (computed by reference to each Bank’s respective Commitment) shall indemnify the Agent, its respective affiliates and the respective shareholders, directors, officers,
employees, agents and counsel of the foregoing (each an “Agent Indemnitee”) and hold each Agent Indemnitee harmless from and against any and all claims (whether groundless or otherwise), liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, (i) the reasonable fees and disbursements of counsel for which the Agent has not been reimbursed by the Borrowers and (ii) any expenses for which the Agent has not been reimbursed by the Borrowers
as required by this Agreement, which may be incurred by such Agent Indemnitee arising out of or related to this Agreement or the transactions contemplated hereby, or the Agent’s actions taken hereunder; provided, that (x) no Agent
Indemnitee shall have the right to be indemnified hereunder for such Agent Indemnitee’s own gross negligence or willful misconduct, as determined by a court of competent jurisdiction, or to the extent that such claim relates to the breach by
such Agent Indemnitee of its obligations under this Agreement, and (y) insofar as the Agent may also be a Bank, the foregoing indemnification in favor of the Agent shall not apply to claims, liabilities, losses, damages, costs and expenses incurred
in its capacity as a Bank. The foregoing shall survive the termination of this Agreement. 
  
 Section 9.08 Setoff. In addition to, and without limitation of, any rights of the Banks under applicable law, if either Borrower or any other Loan Party becomes insolvent, however evidenced, or any Event of Default
occurs, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Obligations at any time held or owing by any Bank or any Affiliate of any Bank to or for the credit
or account of either Borrower or any other Loan Party may be offset and applied toward the payment of the Obligations owing to such Bank, whether or not the Obligations, or any part thereof, shall then be due. 
  
 Section 9.09 Ratable Payments. If any Bank, whether by setoff or otherwise, has
payment made to it upon the Obligations owing to it (other than payments received pursuant to Sections 2.12, 2.13 or 2.14) in a greater proportion than that received by any other Bank, such Bank agrees, promptly upon demand, to purchase a portion of
the Obligations held by the other Banks so that after such purchase each Bank will hold its proportionate share of the Borrowing Base Credit Commitments. If any Bank, whether in connection with setoff or amounts which might be subject to setoff or
otherwise, receives Collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Bank agrees, promptly upon demand, to take such action necessary such that all Banks share in the benefits of such Collateral
ratably in proportion to their respective Borrowing Base Credit Commitments. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

used herein in the singular, where the context so permits, shall be deemed to include the plural or vice versa. The definitions of words in the singular herein shall apply to such words when used in the plural where the context so permits and vice
versa. 
  
 Section 10.08 CONSTRUCTION. THIS AGREEMENT IS, AND THE
NOTES WILL BE, CONTRACTS MADE UNDER AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE UNITED STATES OF AMERICA AND THE INTERNAL LAWS OF THE STATE OF LOUISIANA. 
  
 Section 10.09 Titles of Articles, Sections and Subsections. All titles or
headings to articles, sections, subsections or other divisions of this Agreement or the exhibits hereto are only for the convenience of the parties and shall not be construed to have any effect or meaning with respect to the other content of such
articles, sections, subsections or other divisions, such other content being controlling as to the agreement between the parties hereto. 
  
 Section 10.10 Limitation of Liability. The Loan Documents are executed by officers of the Agent and the Banks, and by acceptance of the Credit Line,
Borrowers agree that for the payment of any claim or the performance of any obligations hereunder resulting from any default by the Agent or any of the Banks, resort shall be had solely to the assets and property of the defaulting Agent or Bank, and
no shareholder, officer, employee or agent of the defaulting Agent or Bank shall be personally liable therefor. 
  
 Section 10.11 Relationship Between the Parties. The relationship between the Agent and the Banks, on the one hand, and Borrowers on the other, shall be
solely that of lender and borrower, and such relationship shall not, under any circumstances whatsoever, be construed to be a joint venture, joint adventure or partnership. Neither the Agent nor any Bank has any fiduciary obligation to either
Borrower, Guarantor or any Subsidiary with respect to this Agreement or the transactions contemplated hereby. 
  
 Section 10.12 Amendment; Waiver. No amendment or waiver of any provision of this Agreement or any other Loan Document (other than Hedging Agreements and
Hedging Arrangements) or consent to any departure therefrom by Borrowers or the Banks shall be effective unless the same shall be in writing and signed by Borrowers, the Agent and the Required Banks; provided, that without the written consent
of all of the Banks, no amendment or waiver to this Agreement or any other Loan Document (other than Hedging Agreements and Hedging Arrangements) shall (i) change the scheduled payment dates or maturity of the Credit Loan, or (ii) change the
principal of or the rate or time of payment of interest or any premium payable with respect to any Note or the fees payable under Section 2.09, or (iii) increase the Commitments, or (iv) release any of the Borrowers, or affect the time, amount or
allocation of any required prepayments, or (v) effect the release of any Collateral (except as contemplated by Sections 5.17 and 8.01(1)) or any guarantor of the Obligations or subordinate the rights of the Agent and the Banks with respect to
Collateral, or (vi) reduce the proportion of the Required Banks required with respect to any consent, or (vii) change the application of payments under Sections 2.09 and 2.17 hereof, 
  

 54 








 or (viii) change the definition of Required Banks or amend this Section 10.12, or (ix) increase or decrease the Borrowing Base. In
addition, but subject to those amendments that require the approval of all Banks, if a Borrower or the Guarantor incurs from time to time additional Debt (other than Obligations) in excess of $30,000,000 not in existence on the Effective Date, then
the Required Banks shall be entitled to require such amendments to this Agreement and the other Loan Documents as they deem to be reasonably appropriate in light of the terms and conditions of such Debt; provided, that (A) absent there being
any Default or Event of Default and absent any circumstances in connection with the incurrence of such Debt that would require a waiver or amendment of the terms and conditions of this Agreement, for example at Section 6.05 hereof (although nothing
herein implies or should be deemed to imply that the Agents or the Banks would agree to any waiver or amendment) and (B) the Leverage Ratio would not have been violated on the last day of the fiscal quarter preceding the incurrence of such Debt had
such Debt been incurred on such date, then the Required Banks shall not be entitled to require amendments to the definitions of Applicable Margin, EBITDA and Net Debt hereunder and Sections 2.09, 5.07, 5.17, 6.05, 6.08, 8.01(n) and 8.01(p) hereof.
Banks not party to a Hedging Agreement or Hedging Arrangement shall not be entitled to consent to any amendments or other modifications thereto of waivers thereof. Bank Affiliates shall not be entitled to consent to any amendments or other
modifications to, or waivers of the Loan Documents, other than their applicable Hedging Agreements as Hedging Arrangements. 
  
 Section 10.13 Entire Agreement. This Agreement and the other Loan Documents supersede all prior written or oral understandings with respect to the
transactions contemplated hereby and thereby. Borrowers are not relying upon any representation by the Agent, any of the Banks or any representative thereof, and no representation has been made, that the Agent or any Bank will, at the time of an
Event of Default or Default, or at any other time, waive, negotiate, discuss or take or refrain from taking any action with respect to any such Event of Default or Default. 
  
 Section 10.14 Time of the Essence. Time shall be deemed of the essence with respect to the performance of all of the terms,
provisions and conditions on the part of Borrowers, the Agent and the Banks to be performed hereunder. 
  
 Section 10.15 Counterparts. This Agreement may be executed in multiple counterparts, and it shall not be necessary that the signatures of all parties hereto
be contained on any one counterpart hereof; each counterpart shall be deemed an original, but all of which together shall constitute one and the same instrument. 
  
 Section 10.16 Interest. It is the intention of the parties hereto to conform strictly to applicable usury laws as presently in
effect. Accordingly, notwithstanding the designation of Louisiana law pursuant to Section 10.08 hereof, if the transactions contemplated hereby are held by a final judgment of a court of competent jurisdiction to be usurious under applicable law
(including the laws of the United States of America or any state other than Louisiana), then, in that event, notwithstanding anything to the contrary in this Agreement, the Notes, the Collateral Documents or the other Loan Documents, the parties
hereto agree as follows: (i) the aggregate of all consideration which constitutes interest under applicable law that is contracted for, charged or received under the Loan Documents shall under no circumstances exceed the maximum amount of interest
allowed by applicable law, and any excess shall be credited on the Obligations (or, if the Obligations shall have been paid in full, refunded to Borrowers for division between themselves as they deem appropriate), and (ii) in the event that the
maturity of the Obligations is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any prepayment, then such consideration that constitutes interest may
never include more than the maximum amount allowed by applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore
paid, shall be credited on the Obligations (or, if the 
  

 55 








 Obligations shall have been paid in full, refunded to Borrowers for division between themselves as they deem appropriate).

  
 Section 10.17 NO THIRD PARTY BENEFICIARY. THERE SHALL BE NO
THIRD PARTY BENEFICIARY OF THIS AGREEMENT, INCLUDING WITHOUT LIMITATION BANK AFFILIATES, GUARANTOR, INDENTURE NOTEHOLDERS AND THE INDENTURE TRUSTEE. 
  
 Section 10.18 SOLIDARY LIABILITY. EACH BORROWER ACKNOWLEDGES AND AGREES THAT IT IS SOLIDARILY (JOINTLY AND SEVERALLY) LIABLE WITH THE OTHER BORROWER FOR
THE PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS FROM TIME TO TIME OWING HEREUNDER AND UNDER THE OTHER LOAN DOCUMENTS EXECUTED BY EITHER OR BOTH OF THE BORROWERS. 
  
 Section 10.19 WAIVERS OF JURY TRIAL. BORROWERS, THE AGENT AND THE BANKS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL
BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN. 
  
 Section 10.20 Bank Affiliates. No Bank Affiliate party to any Hedging Agreement with Borrowers shall have any rights under this Agreement or the other Loan
Documents (other than its Hedging Agreement), except with respect to its rights under, but subject to the terms and conditions of, Section 2.17 hereof to receive proceeds of Collateral or as a result of the Agent’s exercise of other rights and
remedies under the Loan Documents. No Bank Affiliate shall be a third party beneficiary in any respect whatsoever of any of the terms and conditions of this Agreement (including without limitation as to any amendments to or waivers of Section 2.17)
or the other Loan Documents.

thereof as may be advanced pursuant to the Amended and Restated Credit Agreement dated as of February 13, 2004 among the Borrowers, the banks and other financial institutions from time to time party thereto and the Agent, as same may be amended from
time to time (herein called the “Credit Agreement”), whichever is less. 
  
 The credit advice resulting from the deposit of the proceeds of any disbursement hereunder in the Borrowers’ account with the Agent, or the Agent’s copy of any cashier’s check representing all or any part of the
proceeds of the disbursements shall be deemed prima facie evidence of the Borrowers’ indebtedness to the Bank on the Credit Line. 
  
 The unpaid principal of this Note shall bear interest at one (or both) of the following interest rates, at the Borrowers’ option from time to time: (i) Prime
Rate plus the Applicable Margin or (ii) Floating Rate plus the Applicable Margin, as more particularly set forth in the Credit Agreement. The Borrowers shall select the interest rate applicable to each Advance or other portion of the Credit Loan
outstanding (or such interest rate shall otherwise be determined) in accordance with the provisions of the Credit Agreement. Interest after maturity of this Note for any reason whatsoever shall be increased to the Prime Rate plus the Applicable
Margin plus 3% per annum and shall be payable on demand. Interest shall be computed as set forth in the Credit Agreement. 
  
 The Borrowers may or shall from time to time prepay the principal of this Note, and reborrow, in whole or in part, in accordance with the Credit Agreement. Any
prepayment of the principal of this Note shall include accrued interest to the date of prepayment on the principal amount being prepaid and any applicable premium or fee. 
  
 Interest on Advances accruing interest based on the Prime Rate interest option shall be payable monthly in arrears on the last day of
each month beginning February 29, 2004 and on any conversion thereof to accrue interest based on the Floating Rate interest option. Interest on Advances accruing interest based on the Floating Rate interest option shall be payable on the last day of
each Interest Period (30, 60, 90 or 180 days), and in the case of 180 day Interest Periods, also at the end of the first 90 days thereof. The outstanding principal on this Note shall be payable in full at maturity of this Note on the Maturity Date.

  
 This Note is a Credit Note issued pursuant to and is entitled to the
benefit of the Credit Agreement. Reference is made to the Credit Agreement for provisions for the acceleration of the maturity 







 hereof on the occurrence of certain events specified therein, the definition of capitalized terms not otherwise defined herein, and
for all other pertinent purposes. 
  
 All payments and prepayments made by
the Borrowers hereunder shall be made to the Agent in lawful money of the United States, in immediately available funds, before 11:00 a.m. (central time) on the date that such payment is required, or otherwise is, to be made. Any payment received
and accepted by the Agent after such time shall be considered for all purposes (including the calculation of interest, to the extent permitted by law) as having been made on the next following Business Day. Whenever any payment to be made hereunder
falls on a day other than a Business Day, unless otherwise provided in the Credit Agreement, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the calculation of interest.

  
 The Borrowers expressly waive demand and presentment for payment, notice
of nonpayment, protest, notice of protest, notice of dishonor, bringing of suit, diligence in taking any action to collect amounts called for hereunder and in the handling of property at any time existing as security in connection herewith, and
shall be directly and primarily liable for the payment of all sums owing and to be owing hereon, regardless of and without any notice, diligence, act or omission as or with respect to the collection of any amount called for hereunder or in
connection with any right, lien, interest or property at any and all times had or existing as security for any amount called for hereunder. 
  
 If any Event of Default occurs, the Agent and the Lender shall have all of the rights and remedies (including acceleration of the maturity date of this Note)
available to them pursuant to the Credit Agreement or applicable law. 
  
 If
an Event of Default occurs and this Note is placed in the hands of an attorney for collection, or suit is filed hereon, or proceedings are had in bankruptcy, probate, receivership or other judicial proceedings for the establishment or collection of
any amount called for hereunder, or any amount payable or to be payable hereunder is collected through any such proceedings, the Borrowers agree to pay to the Agent and the Lender a reasonable amount as attorney’s fees. 
  
 Irrespective of the Borrower or Borrowers who directly or indirectly receive the
amounts funded on Advances, each of the Borrowers shall be liable jointly and severally and solidarily to the Lender for all amounts outstanding from time to time under this Note. 
  
 This Note shall be governed by and construed in accordance with the laws of the State of Louisiana. 
  
 Neither this Note nor the indebtedness represented by this Note is a novation of the
indebtedness represented by the credit agreement that has been amended and restated by the Credit Agreement or any promissory notes issued under such credit agreement. 







 IN WITNESS WHEREOF, the Borrowers have executed and delivered this Note on the day first written above.
