SECTION 2. Amount and Terms of Credit

2.1. Commitments.

(a) (i) Subject to and upon the terms and conditions herein set forth, each Lender severally (and not jointly) agrees to make a loan or loans denominated in Dollars (each a “Revolving Credit Loan”) to the Borrowers which Revolving Credit Loans (A) shall be made at any time and from time to time on and after the Closing Date and prior to the Maturity Date, (B) may, at the option of the Borrowers be incurred and maintained as, and/or converted into, ABR Loans or Eurodollar Loans, provided that all Revolving Credit Loans made by each of the Lenders pursuant to the same Borrowing shall, unless otherwise specifically provided herein, consist entirely of Revolving Credit Loans of the same Type, (C) may be repaid and reborrowed in accordance with the provisions hereof, (D) shall not, for any such Lender, result in such Lender’s Credit Exposure at such time exceeding such Lender’s Commitment at such time and (E) shall not result in the Total Credit Exposure exceeding the lesser of (i) the Total Commitment at such time and (ii) the Borrowing Base at such time.

Each Lender may at its option make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan, provided that (A) any exercise of such option shall not affect the obligation of the Borrowers to repay such Loan and (B) in exercising such option, such Lender shall use its reasonable efforts to minimize any increased costs to the Borrowers resulting therefrom (which obligation of the Lender shall not require it to take, or refrain from taking, actions that it determines would result in increased costs

-36-

for which it will not be compensated hereunder or that it determines would be otherwise disadvantageous to it and in the event of such request for costs for which compensation is provided under this Agreement, the provisions of Section 3.5 shall apply).

(b) Subject to and upon the terms and conditions herein set forth, the Swingline Lender in its individual capacity agrees, at any time and from time to time on and after the Closing Date and prior to the Swingline Maturity Date, to make a loan or loans (each a “Swingline Loan” and, collectively, the “Swingline Loans”) to the Borrowers in Dollars, which Swingline Loans (i) shall be ABR Loans, (ii) shall have the benefit of the provisions of Section 2.1(c), (iii) shall not exceed at any time outstanding the Swingline Commitment, (iv) shall not result at any time in the Total Credit Exposure at such time exceeding the lesser of (i) the Total Commitment at such time and (ii) the Borrowing Base at such time and (v) may be repaid and reborrowed in accordance with the provisions hereof. On the Swingline Maturity Date, each outstanding Swingline Loan shall be repaid in full. The Swingline Lender shall not make any Swingline Loan after receiving a written notice from the Borrowers or any Lender stating that a Default or Event of Default exists and is continuing until such time as the Swingline Lender shall have received written notice of (i) rescission of all such notices from the party or parties originally delivering such notice or (ii) the waiver of such Default or Event of Default in accordance with the provisions of Section 13.1.

(c) On any Business Day, the Swingline Lender may, in its sole discretion, give notice to the Lenders that all then-outstanding Swingline Loans shall be funded with a Borrowing of Revolving Credit Loans (and, if any Swingline Loan is outstanding on the seventh calendar day following the date of Borrowing of such Swingline Loan, then on the first Business Day following such seventh calendar day, the Swingline Lender shall be required to give such notice), in which case Revolving Credit Loans constituting ABR Loans (each such Borrowing, a “Mandatory Borrowing”) shall be made on the immediately succeeding Business Day by all Lenders with Commitments pro rata based on each Lender’s Applicable Percentage, and the proceeds thereof shall be applied directly to the Swingline Lender to repay the Swingline Lender for such outstanding Swingline Loans. Each Lender hereby irrevocably agrees to make such Revolving Credit Loans upon one Business Day’s notice pursuant to each Mandatory Borrowing in the amount and in the manner specified in the preceding sentence and on the date specified to it in writing by the Swingline Lender notwithstanding (i) that the amount of the Mandatory Borrowing may not comply with the minimum amount for each Borrowing specified in Section 2.2, (ii) whether any conditions specified in Section 7 are then satisfied, (iii) whether a Default or Event of Default has occurred and is continuing, (iv) the date of such Mandatory Borrowing or (v) any reduction in the Total Commitment or Availability after any such Swingline Loans were made. In the event that, in the sole judgment of the Swingline Lender, any Mandatory Borrowing cannot for any reason be made on the date otherwise required above (including as a result of the commencement of a proceeding under the Bankruptcy Code in respect of any Borrower), each Lender hereby agrees that it shall forthwith purchase from the Swingline Lender (without recourse or warranty) such participation of the outstanding Swingline Loans as shall be necessary to cause such Lenders to share in such Swingline Loans ratably based upon their Applicable Percentages, provided that all principal and interest payable on such Swingline Loans shall be for the account of the Swingline Lender until the date the respective participation is purchased and,

-37-

to the extent attributable to the purchased participation, shall be payable to the Lender purchasing the same from and after such date of purchase.

(d) Subject to the limitations set forth below, the Administrative Agent is authorized by the Borrowers and the Lenders, from time to time in the Administrative Agent’s sole discretion (but shall have absolutely no obligation to), to make Loans to the Borrowers, on behalf of all Lenders, which the Administrative Agent, in its Permitted Discretion, deems necessary or desirable (i) to preserve or protect the Collateral, or any portion thereof, (ii) to enhance the likelihood of, or maximize the amount of, repayment of the Loans and other Obligations or (iii) to pay any other amount chargeable to or required to be paid by the Credit Parties pursuant to the terms of this Agreement, including payments of reimbursable expenses (including costs, fees, and expenses as described in Section 13.5) and other sums payable under the Credit Documents (any of such Loans are herein referred to as “Protective Advances”); provided that, the aggregate amount of Protective Advances outstanding at any time shall not at any time exceed the lesser of (x) $5.0 million and (y) 10.0% of the Borrowing Base; provided further that the aggregate amount of outstanding Protective Advances plus the aggregate amount of the other Total Credit Exposure shall not exceed the Total Commitment. Protective Advances may be made even if the conditions precedent set forth in Section 7 have not been satisfied. The Protective Advances shall be secured by the Security Documents and shall constitute Obligations hereunder and under the other Credit Documents. All Protective Advances shall be ABR Loans. The Administrative Agent’s authorization to make Protective Advances may be revoked at any time by the Required Lenders. Any such revocation must be in writing and shall become effective prospectively upon the Administrative Agent’s receipt thereof. At any time that there is sufficient Availability and the conditions precedent set forth in Section 7 have been satisfied, the Administrative Agent may request the Lenders to make a Revolving Credit Loan to repay a Protective Advance. At any other time the Administrative Agent may require the Lenders to fund their risk participations described in Section 2.1(e).

(e) Upon the making of a Protective Advance by the Administrative Agent (whether before or after the occurrence of a Default or Event of Default), each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from the Administrative Agent without recourse or warranty an undivided interest and participation in such Protective Advance in proportion to its Applicable Percentage. On any Business Day, the Administrative Agent may, in its sole discretion, give notice to the Lenders that the Lenders are required to fund their risk participations in Protective Advances (and, if any Protective Advance is outstanding on the thirtieth calendar day following the date of Borrowing of such Protective Advance, then on the first Business Day following such thirtieth calendar day, the Administrative Agent shall give such notice) in which case each Lender shall fund its participation on the date specified in such notice. From and after the date, if any, on which any Lender is required to fund its participation in any Protective Advance purchased hereunder, the Administrative Agent shall promptly distribute to such Lender, such Lender’s Applicable Percentage of all payments of principal and interest and all proceeds of Collateral received by the Administrative Agent in respect of such Protective Advance.

-38-

2.2. Minimum Amount of Each Borrowing; Maximum Number of Borrowings. Each Borrowing of Revolving Credit Loans shall be in a minimum amount of $1,000,000 and in an integral multiple of $500,000 and Swingline Loans shall be in a multiple of $100,000 (except that Mandatory Borrowings shall be made in the amounts required by Section 2.1(c) and Revolving Credit Loans made to refinance Protective Advances pursuant to Section 2.1(e)). More than one Borrowing may be incurred on any date, provided that at no time shall there be outstanding more than five Borrowings of Eurodollar Loans under this Agreement.

2.3. Notice of Borrowing.

(a) Whenever the Borrowers desire to incur Revolving Credit Loans hereunder (other than Mandatory Borrowings, Borrowings to repay Unpaid Drawings or Borrowings to repay Protective Advances), they shall give the Administrative Agent at the Administrative Agent’s Office, (i) prior to 12:00 Noon (New York time) at least three Business Days’ prior written notice (or telephonic notice promptly confirmed in writing) of each Borrowing of Eurodollar Loans, and (ii) prior to 12:00 Noon (New York time) at least one Business Day’s prior written notice (or telephonic notice promptly confirmed in writing) of each Borrowing of ABR Loans (each such notice, a “Notice of Borrowing”). Each such Notice of Borrowing, except as otherwise expressly provided in Section 2.10, shall be irrevocable and shall specify (i) the aggregate principal amount of the Revolving Credit Loans to be made pursuant to such Borrowing, (ii) the date of Borrowing (which shall be a Business Day) and (iii) whether the respective Borrowing shall consist of ABR Loans or Eurodollar Loans and, if Eurodollar Loans, the Interest Period to be initially applicable thereto. The Administrative Agent shall promptly give each Lender written notice (or telephonic notice promptly confirmed in writing) of each proposed Borrowing of Revolving Credit Loans, of such Lender’s Applicable Percentage thereof and of the other matters covered by the related Notice of Borrowing.

(b) Whenever the Borrowers desire to incur Swingline Loans hereunder, they shall give the Administrative Agent written notice (or telephonic notice promptly confirmed in writing) of each Borrowing of Swingline Loans prior to 1:00 p.m. (New York time) on the date of such Borrowing. Each such notice shall be irrevocable and shall specify (i) the aggregate principal amount of the Swingline Loans to be made pursuant to such Borrowing and (ii) the date of Borrowing (which shall be a Business Day). The Administrative Agent shall promptly give the Swingline Lender written notice (or telephonic notice promptly confirmed in writing) of each proposed Borrowing of Swingline Loans and of the other matters covered by the related Notice of Borrowing.

(c) Mandatory Borrowings shall be made upon the notice specified in Section 2.1(c), with the Borrowers irrevocably agreeing, by their incurrence of any Swingline Loan, to the making of Mandatory Borrowings as set forth in such Section.

(d) Borrowings to reimburse Unpaid Drawings shall be made upon the notice specified in Section 3.4(a).

(e) Without in any way limiting the obligation of the Borrowers to confirm in writing any notice they may give hereunder by telephone, the Administrative Agent may act

-39-

prior to receipt of written confirmation without liability upon the basis of such telephonic notice believed by the Administrative Agent in good faith to be from an Authorized Officer of the Borrowers. In each such case, the Borrowers hereby waive the right to dispute the Administrative Agent’s record of the terms of any such telephonic notice.

2.4. Disbursement of Funds.

(a) No later than 12:00 Noon (New York time) on the date specified in each Notice of Borrowing (including Mandatory Borrowings) of Revolving Credit Loans, each Lender will make available its Applicable Percentage, if any, of each Borrowing of Revolving Credit Loans requested to be made on such date in the manner provided below. No later than 3:00 p.m. (New York time) on the date specified in each Notice of Borrowing relating to Swingline Loans, the Swingline Lender shall make available to the Borrowers its Swingline Loan to be made on such date, by depositing to the account of RailAmerica (on behalf of the Borrowers) at the Administrative Agent’s office the amount of such Swingline Loan.

(b) Each Lender shall make available all amounts it is to fund to the Borrowers under any Borrowing in Dollars in immediately available funds to the Administrative Agent at the Administrative Agent’s Office and the Administrative Agent will (except in the case of Mandatory Borrowings and Borrowings to repay Unpaid Drawings and Protective Advances) make available to the Borrowers, by depositing to RailAmerica’s (on behalf of the Borrowers) account at the Administrative Agent’s Office the aggregate of the amounts so made available in Dollars. Unless the Administrative Agent shall have been notified by any Lender prior to the date of any such Borrowing that such Lender does not intend to make available to the Administrative Agent its portion of the Borrowing or Borrowings to be made on such date, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date of Borrowing, and the Administrative Agent, in reliance upon such assumption, may (in its sole discretion and without any obligation to do so) make available to the Borrowers a corresponding amount. If such corresponding amount is not in fact made available to the Administrative Agent by such Lender and the Administrative Agent has made available the same to the Borrowers, the Administrative Agent shall be entitled to recover such corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor the Administrative Agent shall promptly notify the Borrowers and the Borrowers, jointly and severally, shall immediately pay such corresponding amount to the Administrative Agent. The Administrative Agent shall also be entitled to recover from such Lender or the Borrowers, jointly and severally, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Administrative Agent to the Borrowers to the date such corresponding amount is recovered by the Administrative Agent, at a rate per annum equal to (i) if paid by such Lender, the greater of (x) the Federal Funds Effective Rate and (y) a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) if paid by the Borrowers, the then-applicable rate of interest for ABR Loans.

(c) Nothing in this Section 2.4 shall be deemed to relieve any Lender from its obligation to fulfill its commitments hereunder or to prejudice any rights that the Borrowers may

-40-

have against any Lender as a result of any default by such Lender hereunder (it being understood, however, that no Lender shall be responsible for the failure of any other Lender to fulfill its commitments hereunder).

2.5. Repayment of Loans; Evidence of Debt.

(a) The Borrowers, jointly and severally, shall repay to the Administrative Agent in Dollars, for the benefit of the Lenders, on the Maturity Date, the then-unpaid Revolving Credit Loans. The Borrowers, jointly and severally, shall repay to the Administrative Agent in Dollars, for the account of the Swingline Lender, on the Swingline Maturity Date, the then-unpaid Swingline Loans. The Borrowers, jointly and severally, shall repay to the Administrative Agent for the benefit of the Lenders the then-unpaid amount of each Protective Advance on the earlier of the Maturity Date and demand by the Administrative Agent.

(b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrowers to the appropriate lending office of such Lender resulting from each Loan made by such lending office of such Lender from time to time, including the amounts of principal and interest payable and paid to such lending office of such Lender from time to time under this Agreement.

(c) The Administrative Agent shall maintain the Register pursuant to Section 13.6(b), and a subaccount for each Lender, in which Register and subaccounts (taken together) shall be recorded (i) the amount of each Loan made hereunder, whether such Loan is a Revolving Credit Loan, a Swingline Loan or a Protective Advance, the Type of each Loan made and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrowers to each Lender, the Swingline Lender or the Administrative Agent hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder from the Borrowers and each Lender’s share thereof.

(d) The entries made in the Register and accounts and subaccounts maintained pursuant to paragraphs (b) and (c) of this Section 2.5 shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations of the Borrowers therein recorded; provided, however, that the failure of any Lender or the Administrative Agent to maintain such account, such Register or such subaccount, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrowers to repay (with applicable interest) the Loans made to the Borrowers in accordance with the terms of this Agreement.

2.6. Conversions and Continuations.

(a) The Borrowers shall have the option on any Business Day to convert all or a portion equal to at least $1,000,000 of the outstanding principal amount of Revolving Credit Loans made to the Borrowers from one Type into a Borrowing or Borrowings of another Type and the Borrowers shall have the option on any Business Day to continue the outstanding principal amount of any Eurodollar Loans as Eurodollar Loans for an additional Interest Period, provided that (i) no partial conversion of Eurodollar Loans shall reduce the outstanding principal amount of Eurodollar Loans made pursuant to a single Borrowing to less than $1,000,000,

-41-

(ii) ABR Loans may not be converted into Eurodollar Loans if an Event of Default is in existence on the date of the conversion and the Administrative Agent has or the Required Lenders have determined in its or their sole discretion not to permit such conversion, (iii) Eurodollar Loans may not be continued as Eurodollar Loans for an additional Interest Period if an Event of Default is in existence on the date of the proposed continuation and the Administrative Agent has or the Required Lenders have determined in its or their sole discretion not to permit such continuation, (iv) no conversion or continuation of Eurodollar Loans may be made on a day other than the last day of the Interest Period applicable thereto and (v) Borrowings resulting from conversions pursuant to this Section 2.6 shall be limited in number as provided in Section 2.2. Each such conversion or continuation shall be effected by the Borrowers by giving the Administrative Agent at the Administrative Agent’s Office prior to 12:00 noon (New York time) at least three Business Days’ (or one Business Day’s notice in the case of a conversion into ABR Loans) prior written notice (or telephonic notice promptly confirmed in writing) (each a “Notice of Conversion or Continuation”) specifying the Revolving Credit Loans to be so converted or continued, the Type of Revolving Credit Loans to be converted or continued into and, if such Revolving Credit Loans are to be converted into or continued as Eurodollar Loans, the Interest Period to be initially applicable thereto. The Administrative Agent shall give each Lender notice as promptly as practicable of any such proposed conversion or continuation affecting any of its Revolving Credit Loans.

(b) If any Event of Default is in existence at the time of any proposed continuation of any Eurodollar Loans and the Administrative Agent has or the Required Lenders have determined in its or their sole discretion not to permit such continuation, such Eurodollar Loans shall be automatically converted on the last day of the current Interest Period into ABR Loans. If upon the expiration of any Interest Period in respect of Eurodollar Loans, the Borrowers have failed to elect a new Interest Period to be applicable thereto as provided in paragraph (a) above, the Borrowers shall be deemed to have elected to continue such Borrowing of Eurodollar Loans into a Borrowing of Eurodollar Loans with an Interest Period of one month’s duration effective as of the expiration date of such current Interest Period.

2.7. Pro rata Borrowings. Each Borrowing of Revolving Credit Loans under this Agreement shall be granted by the Lenders pro rata on the basis of their Applicable Percentages. It is understood that no Lender shall be responsible for any default by any other Lender in its obligation to make Loans hereunder and that each Lender shall be obligated to make the Loans provided to be made by it hereunder, regardless of the failure of any other Lender to fulfill its commitments hereunder.

2.8. Interest.

(b) The unpaid principal amount of each Eurodollar Loan shall bear interest from the date of the Borrowing thereof until maturity thereof (whether by acceleration or

-42-

otherwise) at a rate per annum that shall at all times be the Eurodollar Margin in effect from time to time plus the relevant Eurodollar Rate.

(c) If there is an Event of Default or if all or a portion of (i) the principal amount of any Loan or (ii) any interest payable thereon or Fee shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), the Obligations shall bear interest at a rate per annum that is (x) in the case of overdue principal, the rate that would otherwise be applicable thereto plus 2% or (y) in the case of any other outstanding amount, to the extent permitted by applicable law, the rate described in Section 2.8(a) plus 2% from and including the date of such non-payment to but excluding the date on which such amount is paid in full (after as well as before judgment).

(d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Commitments; provided that (i) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Loan that is a Revolving Credit Loan prior to the Maturity Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, (ii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion and (iii) interest accrued pursuant to Section 2.8(c) shall be payable on demand.

(e) All computations of interest hereunder shall be made in accordance with Section 5.5.

(f) The Administrative Agent, upon determining the interest rate for any Borrowing of Eurodollar Loans, shall promptly notify the Borrowers and the relevant Lenders thereof. Each such determination shall, absent clearly demonstrable error, be final and conclusive and binding on all parties hereto.

2.9. Interest Periods. At the time the Borrowers give a Notice of Borrowing or Notice of Conversion or Continuation in respect of the making of, or conversion into or continuation as, a Borrowing of Eurodollar Loans (in the case of the initial Interest Period applicable thereto) or prior to 12:00 p.m. (New York time) on the third Business Day prior to the expiration of an Interest Period applicable to a Borrowing of Eurodollar Loans, the Borrowers shall have the right to elect by giving the Administrative Agent written notice (or telephonic notice promptly confirmed in writing) the Interest Period applicable to such Borrowing, which Interest Period shall, at the option of the Borrowers, be a one, two, three, six or, if agreed to by each Lender, a seven or fourteen day period or a nine or twelve month period. Notwithstanding anything to the contrary contained above:

(i) the initial Interest Period for any Borrowing of Eurodollar Loans shall commence on the date of such Borrowing (including the date of any conversion from a Borrowing of ABR Loans) and each Interest Period occurring thereafter in respect of such Borrowing shall commence on the day on which the next preceding Interest Period expires;

-43-

(ii) if any Interest Period relating to a Borrowing of Eurodollar Loans begins on the last Business Day of a calendar month or begins on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period, such Interest Period shall end on the last Business Day of the calendar month at the end of such Interest Period;

(iii) if any Interest Period would otherwise expire on a day that is not a Business Day, such Interest Period shall expire on the next succeeding Business Day, provided that if any Interest Period in respect of a Eurodollar Loan would otherwise expire on a day that is not a Business Day but is a day that is after the last Business Day in such month, such Interest Period shall expire on the next preceding Business Day; and

(iv) the Borrower shall not be entitled to elect any Interest Period in respect of any Eurodollar Loan if such Interest Period would extend beyond the Maturity Date.

2.10. Increased Costs, Illegality, etc.

(a) In the event that (x) in the case of clause (i) below, the Administrative Agent or (y) in the case of clauses (ii) and (iii) below, any Lender shall have reasonably determined (which determination shall, absent clearly demonstrable error, be final and conclusive and binding upon all parties hereto):

(i) on any date for determining the Eurodollar Rate for any Interest Period that (x) deposits in the principal amounts of the Loans comprising such Eurodollar Loan Borrowing are not generally available in the relevant market, (y) by reason of any changes arising on or after the Closing Date affecting the interbank eurodollar market, adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the definition of Eurodollar Rate or (z) the Administrative Agent is advised in writing by the Required Lenders that the Eurodollar Rate for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making their Loans included in such Borrowing for such Interest Period; or

(ii) at any time, that such Lender shall incur increased costs or reductions in the amounts received or receivable hereunder with respect to any Eurodollar Loans (or, in the case of increased costs attributable to Taxes, any Loan) because of (x) any change since the date hereof in any applicable law, governmental rule, regulation, guideline or order (or in the interpretation or administration thereof and including the introduction of any new law or governmental rule, regulation, guideline or order), such as, for example, without limitation, a change in official reserve requirements, and/or (y) other circumstances affecting the interbank eurodollar market or the position of such Lender in such market (provided that in the case of any increased costs attributable to Taxes, this clause (ii) shall apply only to the extent such increased costs resulted from a change in a Requirement of Law after the date such Lender becomes a party hereto, except to the extent such Lender’s assignor, if any, was entitled to compensation for such increased costs immediately prior to such assignment); or

-44-

(iii) at any time, that the making or continuance of any Eurodollar Loan has become unlawful by compliance by such Lender in good faith with any law, governmental rule, regulation, guideline or order (or would conflict with any such governmental rule, regulation, guideline or order not having the force of law even though the failure to comply therewith would not be unlawful), or has become impracticable as a result of a contingency occurring after the date hereof that materially and adversely affects the interbank eurodollar market;

then, and in any such event, such Lender (or the Administrative Agent, in the case of clause (i) above) shall within a reasonable time thereafter give notice (if by telephone, confirmed in writing) to RailAmerica and to the Administrative Agent of such determination (which notice the Administrative Agent shall promptly transmit to each of the other Lenders). Thereafter (x) in the case of clause (i) above, Eurodollar Loans shall no longer be available until such time as the Administrative Agent notifies RailAmerica and the Lenders that the circumstances giving rise to such notice by the Administrative Agent no longer exist (which notice the Administrative Agent agrees to give at such time when such circumstances no longer exist), and any Notice of Borrowing or Notice of Conversion given by the Borrowers with respect to Eurodollar Loans that have not yet been incurred shall be deemed rescinded by the Borrowers, (y) in the case of clause (ii) above, the Borrowers, jointly and severally, shall pay to such Lender, promptly after receipt of written demand therefor such additional amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as such Lender in its reasonable discretion shall determine) as shall be required to compensate such Lender for such increased costs or reductions in amounts receivable hereunder (it being agreed that a written notice as to the additional amounts owed to such Lender, showing in reasonable detail the basis for the calculation thereof, submitted to RailAmerica by such Lender shall, absent clearly demonstrable error, be final and conclusive and binding upon all parties hereto) and (z) in the case of clause (iii) above, the Borrowers shall take one of the actions specified in Section 2.10(b) as promptly as possible and, in any event, within the time period required by law. Notwithstanding anything to the contrary contained herein, this clause (a) shall not apply to any increased costs attributable to (W) any Taxes that are grossed-up or indemnified pursuant to Section 5.4, (X) any Taxes that are described in clause (ii) of the definition of the Excluded Taxes, (Y) any Other Connection Taxes that are imposed on or measured by net income or profits (or franchise or similar taxes imposed in lieu thereof) and (Z) any Other Connection Assignment Taxes as defined in Section 5.4(b).

(b) At any time that any Eurodollar Loan is affected by the circumstances described in Section 2.10(a)(ii) or (iii), the Borrowers may (and in the case of a Eurodollar Loan affected pursuant to Section 2.10(a)(iii) shall) either (x) if the affected Eurodollar Loan is then being made pursuant to a Borrowing, cancel such Borrowing by giving the Administrative Agent telephonic notice (confirmed promptly in writing) thereof on the same date that the Borrowers were notified by a Lender pursuant to Section 2.10(a)(ii) or (iii) or (y) if the affected Eurodollar Loan is then outstanding, upon at least three Business Days’ notice to the Administrative Agent, require the affected Lender to convert each such Eurodollar Loan into an ABR Loan, provided that if more than one Lender is affected at any time, then all affected Lenders must be treated in the same manner pursuant to this Section 2.10(b).

-45-

(c) If, after the date hereof, the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any Governmental Authority, the National Association of Insurance Commissioners, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by a Lender or its parent with any request or directive made or adopted after the date hereof regarding capital adequacy (whether or not having the force of law) of any such authority, association, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Lender’s or its parent’s or its Related Party’s capital or assets as a consequence of such Lender’s commitments or obligations hereunder to a level below that which such Lender or its parent or its Related Party could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration such Lender’s or its parent’s policies with respect to capital adequacy), then from time to time, promptly after demand by such Lender (with a copy to the Administrative Agent), the Borrowers, jointly and severally, shall pay to such Lender such additional amount or amounts as will compensate such Lender or its parent for such reduction, it being understood and agreed, however, that a Lender shall not be entitled to such compensation as a result of such Lender’s compliance with, or pursuant to any request or directive to comply with, any such law, rule or regulation as in effect on the date hereof. Each Lender, upon determining in good faith that any additional amounts will be payable pursuant to this Section 2.10(c), will give prompt written notice thereof to RailAmerica (on its own behalf) which notice shall set forth in reasonable detail the basis of the calculation of such additional amounts, although the failure to give any such notice shall not, subject to Section 2.13, release or diminish any of the Borrowers’ obligations to pay additional amounts pursuant to this Section 2.10(c) upon receipt of such notice.

2.11. Compensation. If (a) any payment of principal of any Eurodollar Loan is made by the Borrowers to or for the account of a Lender other than on the last day of the Interest Period for such Eurodollar Loan as a result of a payment or conversion pursuant to Section 2.5, 2.6, 2.10, 5.1, 5.2 or a required assignment pursuant to 13.7, as a result of acceleration of the maturity of the Loans pursuant to Section 11 or for any other reason, (b) any Borrowing of Eurodollar Loans is not made as a result of a withdrawn Notice of Borrowing, (c) any ABR Loan is not converted into a Eurodollar Loan as a result of a withdrawn Notice of Conversion or Continuation, (d) any Eurodollar Loan is not continued as a Eurodollar Loan as a result of a withdrawn Notice of Conversion or Continuation or (e) any prepayment of principal of any Eurodollar Loan is not made as a result of a withdrawn notice of prepayment pursuant to Section 5.1 or 5.2, the Borrowers, jointly and severally, shall, after receipt of a written request by such Lender (which request shall set forth in reasonable detail the basis for requesting such amount), pay to the Administrative Agent for the account of such Lender any amounts required to compensate such Lender for any additional losses, costs or expenses that such Lender may reasonably incur as a result of such payment, failure to convert, failure to continue or failure to prepay, including any loss, cost or expense (excluding loss of anticipated profits) actually incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Eurodollar Loan.

2.12. Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.10(a)(ii), 2.10(a)(iii), 2.10(b), 3.5 or

-46-

5.4 with respect to such Lender, it will, if requested by the Borrowers, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected by such event, provided that such designation is made on such terms that such Lender and its lending office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of any such Section. Nothing in this Section 2.12 shall affect or postpone any of the obligations of the Borrowers or the right of any Lender provided in Section 2.10, 3.5 or 5.4.

2.13. Notice of Certain Costs. Notwithstanding anything in this Agreement to the contrary, to the extent any notice required by Section 2.10, 2.11, 3.5 or 5.4 is given by any Lender more than 180 days after such Lender has knowledge (or should have had knowledge) of the occurrence of the event giving rise to the additional cost, reduction in amounts, loss, tax or other additional amounts described in such Sections, such Lender shall not be entitled to compensation under Section 2.10, 2.11, 3.5 or 5.4, as the case may be, for any such amounts incurred or accruing prior to the 180th day prior to the giving of such notice to RailAmerica.

2.14. Defaulting Lenders.

(a) Reallocation of Defaulting Lender Commitment, Etc. If a Lender becomes, and during the period it remains, a Defaulting Lender, the following provisions shall apply with respect to any outstanding Letter of Credit Exposure and any outstanding Swingline Exposure of such Defaulting Lender:

(i) the Letter of Credit Exposure and the Swingline Exposure of such Defaulting Lender will, subject to the limitation in the first proviso below, automatically be reallocated (effective on the day such Lender becomes a Defaulting Lender) among the Non-Defaulting Lenders pro rata in accordance with their respective Commitments; provided that (a) the sum of each Non-Defaulting Lender’s total Credit Exposure may not in any event exceed the Commitment of such Non-Defaulting Lender as in effect at the time of such reallocation, (b) neither such reallocation nor any payment by a Non-Defaulting Lender pursuant thereto will constitute a waiver or release of any claim the Borrowers, the Administrative Agent, the Letter of Credit Issuer, the Swingline Lender or any other Lender may have against such Defaulting Lender or cause such Defaulting Lender to be a Non-Defaulting Lender;

(ii) to the extent that any portion (the “unreallocated portion”) of the Defaulting Lender’s Letter of Credit Exposure and Swingline Exposure cannot be so reallocated, whether by reason of the first proviso in clause (i) above or otherwise, the Borrowers will, not later than two Business Days after demand by the Administrative Agent (at the direction of the Letter of Credit Issuer and/or the Swingline Lender, as the case may be), (1) Cash Collateralize the obligations of the Borrowers to the Letter of Credit Issuer and the Swingline Lender in respect of such Letter of Credit Exposure or Swingline Expo-sure, as the case may be, in an amount at least equal to the aggregate amount of the unreallocated portion of such Letter of Credit Exposure or Swingline Exposure, or (2) in the case of such Swingline Exposure, prepay (subject to clause (iii) below) and/or Cash Collateralize in full the unreallocated portion thereof, or (3) make other arrangements

-47-

satisfactory to the Administrative Agent, and to the Letter of Credit Issuer and the Swingline Lender, as the case may be, in their sole discretion to protect them against the risk of non-payment by such Defaulting Lender; and

(iii) any amount paid by the Borrowers for the account of a Defaulting Lender that was or is a Lender under this Agreement (whether on account of principal, interest, fees, indemnity payments or other amounts) will not be paid or distributed to such Defaulting Lender, but will instead be retained by the Administrative Agent in a segregated non-interest bearing account until (subject to Section 2.14(f)) the termination of the Commitments and payment in full of all obligations of the Borrowers hereunder and will be applied by the Administrative Agent, to the fullest extent permitted by law, to the making of payments from time to time in the following order of priority: first to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent under this Agreement, second to the payment of any amounts owing by such Defaulting Lender to the Letter of Credit Issuer or the Swingline Lender (pro rata as to the respective amounts owing to each of them) under this Agreement, third to the payment of post-default interest and then current interest due and payable to the Lenders hereunder other than Defaulting Lenders that are Lenders, ratably among them in accordance with the amounts of such interest then due and payable to them, fourth to the payment of fees then due and payable to the Non-Defaulting Lenders that are Lenders hereunder, ratably among them in accordance with the amounts of such fees then due and payable to them, fifth to pay principal and unreimbursed payments made by the Letter of Credit Issuer pursuant to a Letter of Credit then due and payable to the Non-Defaulting Lenders that are Lenders hereunder ratably in accordance with the amounts thereof then due and payable to them, sixth to the ratable payment of other amounts then due and payable to the Non-Defaulting Lenders that are Lenders, and seventh after the termination of the Commitments and payment in full of all obligations of the Borrowers hereunder, to pay amounts owing under this Agreement to such Defaulting Lender or as a court of competent jurisdiction may otherwise direct.

(b) Cash Collateral Call. If any Lender becomes, and during the period it remains, a Defaulting Lender or a Potential Defaulting Lender, if any Letter of Credit, or Swingline Loan is at the time outstanding, the Letter of Credit Issuer and the Swingline Lender, as the case may be, may (except, in the case of a Defaulting Lender, to the extent the Commitments have been fully reallocated pursuant to Section 2.14(a)), by notice to RailAmerica and such Defaulting Lender or Potential Defaulting Lender through the Administrative Agent, require the Borrowers to Cash Collateralize the obligations of the Borrowers to the Letter of Credit Issuer and the Swingline Lender in respect of such Letter of Credit or Swingline Loan in amount at least equal to the aggregate amount of the unreallocated obligations (contingent or otherwise) of such Defaulting Lender or such Potential Defaulting Lender in respect thereof, or to make other arrangements satisfactory to the Administrative Agent, and to the Letter of Credit Issuer and the Swingline Lender, in their sole discretion to protect them against the risk of non-payment by such Defaulting Lender or Potential Defaulting Lender.

-48-

(c) Right to Give Drawdown Notices. In furtherance of the foregoing, if any Lender becomes, and during the period it remains, a Defaulting Lender or a Potential Defaulting Lender, each of the Letter of Credit Issuer and the Swingline Lender is hereby authorized by the Borrowers (which authorization is irrevocable and coupled with an interest) to give, in its discretion, through the Administrative Agent, Notice of Borrowing pursuant to Section 2.3 in such amounts and in such times as may be required to (i) reimburse an outstanding L/C Participation, (ii) repay an outstanding Swingline Loan, and/or (iii) Cash Collateralize the obligations of the Borrowers in respect of outstanding Letters of Credit or Swingline Loans in an amount at least equal to the aggregate amount of the obligations (contingent or otherwise) of such Defaulting Lender or Potential Defaulting Lender in respect of such Letter of Credit or Swingline Loan.

(d) Fees. Anything herein to the contrary notwithstanding, during such period as a Lender is a Defaulting Lender, such Defaulting Lender will not be entitled to any fees accruing during such period pursuant to Section 4.1 (without prejudice to the rights of the Lenders other than Defaulting Lenders in respect of such fees), provided that in the case of a Defaulting Lender that was or is a Lender (x) to the extent that a portion of the Letter of Credit Exposure or the Swingline Exposure of such Defaulting Lender is reallocated to the Non-Defaulting Lenders pursuant to Section 2.14(a), such fees that would have accrued for the benefit of such Defaulting Lender will instead accrue for the benefit of and be payable to such Non-Defaulting Lenders, pro rata in accordance with their respective Commitments, and (y) to the extent any portion of such Letter of Credit Exposure or Swingline Exposure cannot be so reallocated, such fees will instead accrue for the benefit of and be payable to the Letter of Credit Issuer and the Swingline Lender, as applicable, as their interests appear (and the pro rata payment provisions of Section 5.3 will automatically be deemed adjusted to reflect the provisions of this Section).

(e) Termination of Defaulting Lender Commitment. The Borrowers may terminate the unused amount of the Commitment of a Defaulting Lender upon not less than three Business Days’ prior notice to the Administrative Agent (which will promptly notify the Lenders thereof), and in such event the provisions of Section 2.14(a)(iii) will apply to all amounts thereafter paid by the Borrowers for the account of such Defaulting Lender that is a Lender under this Agreement (in each case whether on account of principal, interest, fees, indemnity or other amounts), provided that such termination will not be deemed to be a waiver or release of any claim the Borrowers, the Administrative Agent, the Letter of Credit Issuer, the Swingline Lender or any Lender may have against such Defaulting Lender.

(f) Cure. If the Borrowers, the Administrative Agent, the Letter of Credit Issuer and the Swingline Lender agree in writing in their discretion that a Lender that is a Defaulting Lender or a Potential Defaulting Lender should no longer be deemed to be a Defaulting Lender or Potential Defaulting Lender, as the case may be, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any amounts then held in the segregated account referred to in Section 2.14(a)), such Lender will, to the extent applicable, purchase such portion of outstanding Loans of the other Lenders and/or make such other adjustments as the Administrative Agent may determine to be necessary to cause the Credit Exposure, Letter of Credit Exposure and Swingline Exposure of the Lenders to be on a pro rata

-49-

basis in accordance with their respective Commitments, whereupon such Lender will cease to be a Defaulting Lender or Potential Defaulting Lender and will be a Non-Defaulting Lender (and such Exposure of each Lender will automatically be adjusted on a prospective basis to reflect the foregoing); provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrowers while such Lender was a Defaulting Lender; and provided further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender or Potential Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender or Potential Defaulting Lender.

2.15. Incremental Facilities. The Borrowers may by written notice to the Administrative Agent elect to request, prior to the Maturity Date, an increase to the existing Commitments (any such increase, the “New Commitments”) by an amount not in excess of $20.0 million in the aggregate and not less than $5.0 million individually (or such lesser amount which shall be approved by Administrative Agent), and integral multiples of $1.0 million in excess of that amount. Each such notice shall specify (A) the date (each, an “Increased Amount Date”) on which the Borrowers propose that the New Commitments shall be effective, which shall be a date not less than 10 Business Days after the date on which such notice is delivered to the Administrative Agent and (B) the identity of each Lender or other Person that is an eligible assignee pursuant to Section 13.6(b) (each, a “New Lender”) to whom the Borrowers propose any portion of such New Commitments be allocated and the amounts of such allocations; provided that the Borrowers shall first approach the Lenders to provide all of the New Commitments in accordance with their Applicable Percentages (excluding for this purpose the Commitment of any Lender that declines to provide any portion of the New Commitments) prior to approaching any other Person that is an eligible assignee pursuant to Section 13.6(b) (and no such Person shall be offered to provide the New Commitments on terms (including with respect to upfront fees and other economic terms) that are more favorable to such Person than the terms offered to the existing Lenders) and no Lender shall provide a New Commitment unless the Administrative Agent, the Swingline Lender and the Letter of Credit Issuer shall have consented thereto; provided further that any Lender approached to provide all or a portion of the New Commitments may elect or decline, in its sole discretion, to provide a New Commitment. Such New Commitments shall become effective, as of such Increased Amount Date; provided that (1) no Default or Event of Default shall exist on such Increased Amount Date before or after giving effect to such New Commitments; (2) the New Commitments shall be effected pursuant to one or more Joinder Agreements executed and delivered by the Borrowers, the Lender providing the New Commitment and Administrative Agent, and each of which shall be recorded in the Register and shall be subject to the requirements set forth in Section 5.4(c); (3) the Borrowers shall make any payments required pursuant to Section 2.11 in connection with the New Commitments; (4) the Borrowers shall deliver or cause to be delivered any legal opinions or other documents reasonably requested by Administrative Agent in connection with any such transaction and (5) after giving effect to the New Commitments, Availability is not less than zero.

On any Increased Amount Date, subject to the satisfaction of the foregoing terms and conditions, (a) each of the Lenders with Commitments shall assign to each of the New Lenders, and each of the New Lenders shall purchase from each of the Lenders with Commitments, at

-50-

the principal amount thereof (together with accrued interest), such interests in the Revolving Credit Loans outstanding on such Increased Amount Date as shall be necessary in order that, after giving effect to all such assignments and purchases, such Revolving Credit Loans will be held by existing Lenders with Revolving Credit Loans and New Lenders ratably in accordance with their respective Commitments after giving effect to the addition of such New Commitments to the Commitments, (b) each New Commitment shall be deemed for all purposes a Commitment and each Loan made thereunder shall be deemed, for all purposes, a Revolving Credit Loan and (c) each New Lender shall become a Lender with respect to the New Commitment and all matters relating thereto.

The Administrative Agent shall notify the Collateral Agent and the Lenders promptly upon receipt of the Borrowers’ notice of each Increased Amount Date and in respect thereof (y) the New Commitments and the New Lenders and (z) the respective interests in such Lender’s Revolving Credit Loans, in each case subject to the assignments contemplated by this Section.

2.16. Reserves. Notwithstanding anything to the contrary, the Administrative Agent may at any time and from time to time in the exercise of its Permitted Discretion establish and increase or decrease Reserves; provided that the Administrative Agent shall have provided the Borrowers at least 2 Business Days’ prior written notice of any such establishment or increase.

SECTION 3. Letters of Credit

3.1. Letters of Credit.

(a) Subject to and upon the terms and conditions herein set forth, at any time and from time to time after the Closing Date and thirty calendar days prior to the Maturity Date, (i) the Borrowers may request that the Letter of Credit Issuer issue for the account of the Borrowers a Letter of Credit or Letters of Credit in Dollars in such form as may be approved by the Letter of Credit Issuer in its reasonable discretion.

(b) Notwithstanding the foregoing, (i) no Letter of Credit shall be issued the Stated Amount of which, when added to the Letters of Credit Outstanding at such time, would exceed the Letter of Credit Commitment then in effect; (ii) no Letter of Credit shall be issued, amended (to increase the Stated Amount thereof), extended or renewed if, after giving effect to such issuance, amendment, extension or renewal, the Total Credit Exposure would exceed the lesser of (x) the Total Commitment then in effect and (y) the Borrowing Base then in effect; (iii) each Letter of Credit shall have an expiration date occurring no later than one year after the date of issuance thereof, unless otherwise agreed upon by the Administrative Agent and the Letter of Credit Issuer, provided that in no event shall such expiration date occur later than the L/C Maturity Date; (iv) no Letter of Credit shall be issued if it would be illegal under any applicable law for the beneficiary of the Letter of Credit to have a Letter of Credit issued in its favor; and (v) no Letter of Credit shall be issued by a Letter of Credit Issuer after it has received a written notice from the Borrowers or any Lender stating that a Default or Event of Default has occurred and is continuing until such time as the Letter of Credit Issuer shall have received a

-51-

written notice of (x) rescission of such notice from the party or parties originally delivering such notice or (y) the waiver of such Default or Event of Default in accordance with the provisions of Section 13.1.

(c) Upon at least one Business Day’s prior written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent and the Letter of Credit Issuer (which notice the Administrative Agent shall promptly transmit to each of the applicable Lenders), the Borrowers shall have the right, on any day, permanently to terminate or reduce the Letter of Credit Commitment in whole or in part, provided that, after giving effect to such termination or reduction, the Letters of Credit Outstanding shall not exceed the Letter of Credit Commitment.

3.2. Letter of Credit Requests.

(a) Whenever the Borrowers desire that a Letter of Credit be issued for their account, they shall give the Administrative Agent and the Letter of Credit Issuer at least five (or such lesser number as may be agreed upon by the Administrative Agent and the Letter of Credit Issuer) Business Days’ written notice thereof. Each notice shall be executed by the Borrowers and shall be in the form of Exhibit G (each a “Letter of Credit Request”). The Administrative Agent shall promptly transmit copies of each Letter of Credit Request to each Lender.

(b) The making of each Letter of Credit Request shall be deemed to be a representation and warranty by the Borrowers that the Letter of Credit may be issued in accordance with, and will not violate the requirements of, Section 3.1(b).

3.3. Letter of Credit Participations.

(a) Immediately upon the issuance by the Letter of Credit Issuer of any Letter of Credit, the Letter of Credit Issuer shall be deemed to have sold and transferred to each other Lender that has a Commitment (each such other Lender, in its capacity under this Section 3.3, an “L/C Participant”), and each such L/C Participant shall be deemed irrevocably and unconditionally to have purchased and received from the Letter of Credit Issuer, without recourse or warranty, an undivided interest and participation (each an “L/C Participation”), to the extent of such L/C Participant’s Applicable Percentage of such Letter of Credit, each substitute letter of credit, each drawing made thereunder and the obligations of the Borrowers under this Agreement with respect thereto, and any security therefor or guaranty pertaining thereto (although Letter of Credit Fees will be paid directly to the Administrative Agent for the ratable account of the L/C Participants as provided in Section 4.1(b) and the L/C Participants shall have no right to receive any portion of any Fronting Fees).

(b) In determining whether to pay under any Letter of Credit, the Letter of Credit Issuer shall have no obligation relative to the L/C Participants other than to confirm that any documents required to be delivered under such Letter of Credit have been delivered and that they appear to comply on their face with the requirements of such Letter of Credit. Any action taken or omitted to be taken by the Letter of Credit Issuer under or in connection with any Letter

-52-

of Credit issued by it, if taken or omitted in the absence of gross negligence or willful misconduct, shall not create for the Letter of Credit Issuer any resulting liability.

(c) In the event that the Letter of Credit Issuer makes any payment under any Letter of Credit issued by it and the Borrowers shall not have repaid such amount in full to the respective Letter of Credit Issuer pursuant to Section 3.4(a), the Letter of Credit Issuer shall promptly notify the Administrative Agent and each L/C Participant of such failure, and each L/C Participant shall promptly and unconditionally pay to the Administrative Agent, for the account of the Letter of Credit Issuer, the amount of such L/C Participant’s Applicable Percentage of such unreimbursed payment in Dollars and in immediately available funds; provided, however, that no L/C Participant shall be obligated to pay to the Administrative Agent for the account of the Letter of Credit Issuer its Applicable Percentage of such unreimbursed amount arising from any wrongful payment made by the Letter of Credit Issuer under a Letter of Credit as a result of acts or omissions constituting willful misconduct or gross negligence on the part of the Letter of Credit Issuer. If the Letter of Credit Issuer so notifies, prior to 11:00 a.m. (New York time) on any Business Day, any L/C Participant required to fund a payment under a Letter of Credit, such L/C Participant shall make available to the Administrative Agent for the account of the Letter of Credit Issuer such L/C Participant’s Applicable Percentage of the amount of such payment on such Business Day in immediately available funds. If and to the extent such L/C Participant shall not have so made its Applicable Percentage of the amount of such payment available to the Administrative Agent, for the account of the Letter of Credit Issuer, such L/C Participant agrees to pay to the Administrative Agent, for the account of the Letter of Credit Issuer, forthwith on demand, such amount, together with interest thereon for each day from such date until the date such amount is paid to the Administrative Agent, for the account of the Letter of Credit Issuer at a rate equal to the greater of (x) the Federal Funds Effective Rate and (y) a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. The failure of any L/C Participant to make available to the Administrative Agent, for the account of the Letter of Credit Issuer, its Applicable Percentage of any payment under any Letter of Credit shall not relieve any other L/C Participant of its obligation hereunder to make available to the Administrative Agent, for the account of the Letter of Credit Issuer its Applicable Percentage of any payment under such Letter of Credit on the date required, as specified above, but, except as provided Section 2.14, no L/C Participant shall be responsible for the failure of any other L/C Participant to make available to the Administrative Agent such other L/C Participant’s Applicable Percentage of any such payment.

(d) Whenever the Letter of Credit Issuer receives a payment in respect of an unpaid reimbursement obligation as to which the Administrative Agent has received for the account of the Letter of Credit Issuer any payments from the L/C Participants pursuant to paragraph (c) above, the Letter of Credit Issuer shall pay to the Administrative Agent and the Administrative Agent shall promptly pay to each L/C Participant that has paid its Applicable Percentage of such reimbursement obligation, in Dollars and in immediately available funds, an amount equal to such L/C Participant’s share (based upon the proportionate aggregate amount originally funded by such L/C Participant to the aggregate amount funded by all L/C Participants) of the principal amount of such reimbursement obligation and interest thereon accruing after the purchase of the respective L/C Participations.

-53-

(e) The obligations of the L/C Participants to make payments to the Administrative Agent for the account of the Letter of Credit Issuer with respect to Letters of Credit shall be irrevocable and not subject to counterclaim, set-off or other defense or any other qualification or exception whatsoever and shall be made in accordance with the terms and conditions of this Agreement under all circumstances, including under any of the following circumstances:

(i) any lack of validity or enforceability of this Agreement or any of the other Credit Documents;

(ii) the existence of any claim, set-off, defense or other right that the Borrowers may have at any time against a beneficiary named in a Letter of Credit, any transferee of any Letter of Credit (or any Person for whom any such transferee may be acting), the Administrative Agent, the Letter of Credit Issuer, any Lender or other Person, whether in connection with this Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated transactions (including any underlying transaction between the Borrowers and the beneficiary named in any such Letter of Credit);

(iii) any draft, certificate or any other document presented under any Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

(iv) the surrender or impairment of any security for the performance or observance of any of the terms of any of the Credit Documents; or

(v) the occurrence of any Default or Event of Default;

provided, however, that no L/C Participant shall be obligated to pay to the Administrative Agent for the account of the Letter of Credit Issuer its Applicable Percentage of any unreimbursed amount arising from any wrongful payment made by the Letter of Credit Issuer under a Letter of Credit as a result of acts or omissions constituting willful misconduct or gross negligence on the part of the Letter of Credit Issuer.

3.4. Agreement to Repay Letter of Credit Drawings.

(a) The Borrowers, jointly and severally, hereby agree to reimburse the Letter of Credit Issuer, by making payment in Dollars to the Administrative Agent in immediately available funds for any payment or disbursement made by the Letter of Credit Issuer under any Letter of Credit (each such amount so paid until reimbursed, an “Unpaid Drawing”) immediately after, and in any event on the date of, such payment, with interest on the amount so paid or disbursed by the Letter of Credit Issuer, to the extent not reimbursed prior to 5:00 p.m. (New York time) on the date of such payment or disbursement, from and including the date paid or disbursed to but excluding the date the Letter of Credit Issuer is reimbursed therefor at a rate per annum that shall at all times be the ABR Margin plus the ABR as in effect from time to time, provided that, notwithstanding anything contained in this Agreement to the contrary, (i) unless the Borrowers shall have notified the Administrative Agent and the Letter of Credit Issuer prior to 10:00 a.m. (New York time) on the date of such drawing that the Borrowers intend to reimburse

-54-

the Letter of Credit Issuer for the amount of such drawing with funds other than the proceeds of Loans, the Borrowers shall be deemed to have given a Notice of Borrowing requesting that the Lenders with Commitments make Revolving Credit Loans (which shall be ABR Loans) on the date on which such drawing is honored in an amount equal to the amount of such drawing and (ii) the Administrative Agent shall promptly notify each relevant L/C Participant of such drawing and the amount of its Revolving Credit Loan to be made in respect thereof, and, subject to the conditions set forth in Section 2.1(a), each L/C Participant shall be irrevocably obligated to make a Revolving Credit Loan to the Borrowers in the manner deemed to have been requested in the amount of its Applicable Percentage of the applicable Unpaid Drawing by 12:00 noon (New York time) on such Business Day by making the amount of such Revolving Credit Loan available to the Administrative Agent. Such Revolving Credit Loans shall be made without regard to the minimum Borrowing amount for ABR Loans set forth in Section 2.2. The Administrative Agent shall use the proceeds of such Revolving Credit Loans solely for purpose of reimbursing the Letter of Credit Issuer for the related Unpaid Drawing.

(b) The obligations of the Borrowers under this Section 3.4 to reimburse the Letter of Credit Issuer with respect to Unpaid Drawings (including, in each case, interest thereon) shall be absolute and unconditional under any and all circumstances and irrespective of any set-off, counterclaim or defense to payment that the Borrowers or any other Person may have or have had against the Letter of Credit Issuer, the Administrative Agent or any Lender (including in its capacity as a L/C Participant), including any defense based upon the failure of any drawing under a Letter of Credit (each a “Drawing”) to conform to the terms of the Letter of Credit or any non-application or misapplication by the beneficiary of the proceeds of such Drawing, provided that the Borrowers shall not be obligated to reimburse the Letter of Credit Issuer for any wrongful payment made by the Letter of Credit Issuer under the Letter of Credit issued by it as a result of acts or omissions constituting willful misconduct or gross negligence on the part of the Letter of Credit Issuer (as determined in a final non-appealable judgment by a court of competent jurisdiction).

3.5. Increased Costs. If after the date hereof, the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or actual compliance by the Letter of Credit Issuer or any L/C Participant with any request or directive made or adopted after the date hereof (whether or not having the force of law), by any such authority, central bank or comparable agency shall either (a) impose, modify or make applicable any reserve, deposit, capital adequacy or similar requirement against letters of credit issued by the Letter of Credit Issuer, or any L/C Participant’s L/C Participation therein, or (b) impose on the Letter of Credit Issuer or any L/C Participant any other conditions affecting its obligations under this Agreement in respect of Letters of Credit or L/C Participations therein or any Letter of Credit or such L/C Participant’s L/C Participation therein, and the result of any of the foregoing is to increase the cost to the Letter of Credit Issuer or such L/C Participant of issuing, maintaining or participating in any Letter of Credit, or to reduce the amount of any sum received or receivable by the Letter of Credit Issuer or such L/C Participant hereunder in respect of Letters of Credit or L/C Participations therein, then, promptly after receipt of written demand to the Borrowers by the Letter of Credit Issuer or such L/C

-55-

Participant, as the case may be (a copy of which notice shall be sent by the Letter of Credit Issuer or such L/C Participant to the Administrative Agent), the Borrowers, jointly and severally, shall pay to the Letter of Credit Issuer or such L/C Participant such additional amount or amounts as will compensate the Letter of Credit Issuer or such L/C Participant for such increased cost or reduction, it being understood and agreed, however, that the Letter of Credit Issuer or a L/C Participant shall not be entitled to such compensation as a result of such Person’s compliance with, or pursuant to any request or directive to comply with, any such law, rule or regulation as in effect on the date hereof. A certificate submitted to the Borrowers by the relevant Letter of Credit Issuer or a L/C Participant, as the case may be, (a copy of which certificate shall be sent by the Letter of Credit Issuer or such L/C Participant to the Administrative Agent), setting forth in reasonable detail the basis for the determination of such additional amount or amounts necessary to compensate the Letter of Credit Issuer or such L/C Participant as aforesaid shall be conclusive and binding on the Borrowers absent clearly demonstrable error. Notwithstanding anything to the contrary contained herein, (I) in the case of any increased costs attributable to Taxes, this Section 3.5 shall apply to only to the extent such increased costs resulted from a change in Requirement of Law after the date such Lender becomes a party hereto, except to the extent such Lender’s assignor, if any, was entitled to compensation for such increased costs immediately prior to such assignment and (ii) this Section 3.5 shall not apply to any increased costs attributable to (W) any Taxes that are grossed-up or indemnified pursuant to Section 5.4, (X) any Taxes that are described in clause (ii) of the definition of the Excluded Taxes, (Y) any Other Connection Taxes that are imposed on or measured by net income or profits (or franchise or similar taxes imposed in lieu thereof) and (Z) any Other Connection Assignment Taxes as defined in Section 5.4(b).

3.6. Successor Letter of Credit Issuer. A Letter of Credit Issuer may resign as Letter of Credit Issuer upon 60 days’ prior written notice to the Administrative Agent, the Lenders and RailAmerica. If the Letter of Credit Issuer shall resign as Letter of Credit Issuer under this Agreement, then the Borrowers shall appoint from among the Lenders (with the consent of such Lender) with Commitments a successor issuer of Letters of Credit, whereupon such successor issuer shall succeed to the rights, powers and duties of the Letter of Credit Issuer, and the term “Letter of Credit Issuer” shall mean such successor issuer effective upon such appointment (except with respect to Letters of Credit issued by the resigning Letter of Credit Issuer). After the resignation of the Letter of Credit Issuer hereunder, the resigning Letter of Credit Issuer shall remain a party hereto and shall continue to have all the rights and obligations of a Letter of Credit Issuer under this Agreement and the other Credit Documents with respect to Letters of Credit issued by it prior to such resignation, but shall not be required to issue additional Letters of Credit. After any retiring Letter of Credit Issuer’s resignation as Letter of Credit Issuer, the provisions of this Agreement relating to the Letter of Credit Issuer shall inure to its benefit as to any actions taken or omitted to be taken by it (a) while it was Letter of Credit Issuer under this Agreement or (b) at any time with respect to Letters of Credit issued by such Letter of Credit Issuer.

3.7. Cash Collateralization. If any Event of Default shall occur and be continuing, on the Business Day that RailAmerica receives notice from the Administrative Agent or the Required Lenders demanding the deposit of cash collateral pursuant to this paragraph, the

-56-

Borrowers shall deposit on terms and in accounts satisfactory to the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to one hundred five percent (105%) of the Letters of Credit Outstanding as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrowers described in Section 11.5. Funds so deposited shall be applied by the Administrative Agent to reimburse the Letter of Credit Issuer for Unpaid Drawings for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of outstanding Unpaid Drawings or, if the maturity of the Loans has been accelerated, be applied to satisfy other Obligations of the Borrowers under this Agreement. If the Borrowers are required to provide an amount of cash collateral under this Section 3.7 as a result of the occurrence of an Event of Default, such amount plus any accrued interest or realized profits with respect to such amounts (to the extent not applied as aforesaid) shall be returned to the Borrowers within three Business Days after all Events of Default have been cured or waived.

SECTION 4. Fees; Commitments

4.1. Fees.

(a) The Borrowers, jointly and severally, agree to pay to the Administrative Agent in Dollars, for the account of each Lender having a Commitment (in each case pro rata according to the respective Applicable Percentages of all such Lenders), a commitment fee for each day from and including the Closing Date to but excluding the Maturity Date. Such commitment fee shall be payable in arrears (i) on the first day of each January, April, July and October (for the three-month period (or portion thereof) ended on the preceding day for which no payment has been received) and (ii) on the Final Date (for the period ended on such date for which no payment has been received pursuant to clause (i) above), and shall be computed for each day during such period at a rate per annum equal to the Commitment Fee Rate in effect on such day on the Available Commitments in effect on such day.

(b) The Borrowers, jointly and severally, agree to pay to the Administrative Agent in Dollars for the account of the Lenders pro rata on the basis of their respective Applicable Percentages, a fee in respect of each Letter of Credit (the “Letter of Credit Fee”), for the period from and including the date of issuance of such Letter of Credit to but excluding the termination date of such Letter of Credit computed at the per annum rate for each day equal to the Eurodollar Margin for Revolving Credit Loans on the average daily Stated Amount of such Letter of Credit. Such Letter of Credit Fees shall be due and payable quarterly in arrears on the first day of each April, July, October and January and on the date upon which the Total Commitment terminates and the Letters of Credit Outstanding shall have been reduced to zero.

(c) The Borrowers, jointly and severally, agree to pay to the Administrative Agent in Dollars for the account of the Letter of Credit Issuer a fee in respect of each Letter of Credit issued by it (the “Fronting Fee”), for the period from and including the date of issuance of such Letter of Credit to but excluding the termination date of such Letter of Credit, computed at the rate for each day equal to 0.25% per annum on the average daily Stated Amount of such

-57-

Letter of Credit. Such Fronting Fees shall be due and payable quarterly in arrears on the first day of each April, July, October and January and on the date upon which the Total Commitment terminates and the Letters of Credit Outstanding shall have been reduced to zero.

(d) The Borrowers, jointly and severally, agree to pay directly to the Letter of Credit Issuer in Dollars upon each issuance of, drawing under, and/or amendment of, a Letter of Credit issued by it such Letter of Credit Issuer’s customary fees for issuances of, drawings under or amendments of, Letters of Credit issued by it.

(e) The Borrowers, jointly and severally, agree to pay the fees to the Administrative Agent as set forth in the Administrative Agent Fee Letter.

4.2. Voluntary Reduction of Commitments. Upon at least three Business Days’ prior written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent at the Administrative Agent’s Office (which notice the Administrative Agent shall promptly transmit to each of the Lenders), the Borrowers shall have the right, without premium or penalty, on any day, permanently to terminate or reduce the Commitments in whole or in part, provided that (a) any such reduction shall apply proportionately and permanently to reduce the Commitment of each of the Lenders in accordance with their Applicable Percentages, (b) any partial reduction pursuant to this Section 4.2 shall be in the amount of at least $1,000,000 and (c) after giving effect to such termination or reduction and to any prepayments of the Loans made on the date thereof in accordance with this Agreement, (i) the Total Credit Exposure shall not exceed the lesser of (x) the Total Commitment and (y) the Borrowing Base.

4.3. Mandatory Termination of Commitments.

(a) The Total Commitment shall terminate at 5:00 p.m. (New York time) on the Maturity Date.

(b) The Swingline Commitment shall terminate at 5:00 p.m. (New York time) on the Swingline Maturity Date.

SECTION 5. Payments

5.1. Voluntary Prepayments. The Borrowers shall have the right to prepay Revolving Credit Loans and Swingline Loans in whole or in part from time to time on the following terms and conditions: (a) the Borrowers shall give the Administrative Agent at the Administrative Agent’s Office written notice (or telephonic notice promptly confirmed in writing) of their intent to make such prepayment, the amount of such prepayment and (in the case of Eurodollar Loans) the specific Borrowing(s) pursuant to which made, which notice shall be given by the Borrowers no later than (i) in the case of Revolving Credit Loans, 10:00 a.m. (New York time) one Business Day prior to, or (ii) in the case of Swingline Loans or Protective Advances, 10:00 a.m. (New York time) on, the date of such prepayment and, in the case of a prepayment of Revolving Credit Loans or Swingline Loans shall promptly be transmitted by the Administrative Agent to each of the Lenders or the Swingline Lender, as the case may be; (b) each partial prepayment of any Borrowing of Revolving Credit Loans shall be in a multiple of $500,000 and in

-58-

an aggregate principal amount of at least $1,000,000 and each partial prepayment of Swingline Loans or Protective Advances shall be in a multiple of $500,000 and in an aggregate principal amount of at least $500,000, provided that no partial prepayment of Eurodollar Loans made pursuant to a single Borrowing shall reduce the outstanding Eurodollar Loans made pursuant to such Borrowing to an amount less than $1,000,000; and (c) any prepayment of Eurodollar Loans pursuant to this Section 5.1 on any day other than the last day of an Interest Period applicable thereto shall be subject to compliance by the Borrowers with the applicable provisions of Section 2.11. Notwithstanding the foregoing, the Borrowers shall not be permitted to prepay any Revolving Credit Loans or Swingline Loans under this Agreement, in whole or in part, if at such time, any Protective Advances are outstanding.

5.2. Mandatory Prepayments.

(a) Mandatory Prepayments of Loans. If on any date the Total Credit Exposure exceeds the lesser of (x) the Total Commitment and (y) the Borrowing Base, the Borrowers shall forthwith repay on such date the principal amount of Protective Advances and, after all Protective Advances have been paid in full, Swingline Loans and, after all Swingline Loans have been paid in full, Revolving Credit Loans in an amount equal to such excess. If, after giving effect to the prepayment of all outstanding Protective Advances, Swingline Loans and Revolving Credit Loans, the Total Credit Exposure exceeds the lesser of (x) the Total Commitment and (y) the Borrowing Base, the Borrowers, jointly and severally, shall pay to the Administrative Agent an amount in cash equal to such excess and the Administrative Agent shall hold such payment for the benefit of the Lenders as security for the Obligations of the Borrowers hereunder (including one hundred five percent (105%) of Obligations in respect of Letters of Credit Outstanding) pursuant to a cash collateral agreement to be entered into in form and substance reasonably satisfactory to the Administrative Agent. Additionally, if on any date the Total Credit Exposure exceeds the Total Commitment for any reason, the Borrowers shall forthwith reduce the Total Credit Exposure in the manner provided above.

(b) Application to Revolving Credit Loans. With respect to each prepayment of Revolving Credit Loans required by Section 5.2(a), the Borrowers may designate the Types of Loans that are to be prepaid and the specific Borrowing(s) pursuant to which made, provided that (x) Eurodollar Loans may be designated for prepayment pursuant to this Section 5.2 only on the last day of an Interest Period applicable thereto unless all Eurodollar Loans with Interest Periods ending on such date of required prepayment and all ABR Loans have been paid in full; (y) if any prepayment by the Borrowers of Eurodollar Loans made pursuant to a single Borrowing shall reduce the outstanding amount of the Revolving Credit Loans made pursuant to such Borrowing to an amount less than $1,000,000, such Borrowing shall immediately be converted into ABR Loans; and (z) each prepayment of any Revolving Credit Loans made pursuant to a Borrowing shall be applied pro rata among such Revolving Credit Loans of each Lender in accordance with their respective Applicable Percentages. In the absence of a designation by the Borrowers as described in the preceding sentence, the Administrative Agent shall, subject to the above, make such designation in its reasonable discretion with a view, but no obligation, to minimize breakage costs owing under Section 2.11.

-59-

(c) Interest Periods. In lieu of making any payment pursuant to this Section 5.2 in respect of any Eurodollar Loan other than on the last day of the Interest Period therefor so long as no Event of Default shall have occurred and be continuing, the Borrowers at their option may deposit with the Administrative Agent an amount equal to the amount of the Eurodollar Loan to be prepaid and such Eurodollar Loan shall be repaid on the last day of the Interest Period therefor in the required amount. Such deposit shall be held by the Administrative Agent in a corporate time deposit account established on terms reasonably satisfactory to the Administrative Agent, earning interest at the then-customary rate for accounts of such type. Such deposit shall constitute cash collateral for the Obligations, provided that the Borrowers may at any time direct that such deposit be applied to make the applicable payment required pursuant to this Section 5.2.

(d) Cash Dominion Period. On each Business Day during any Cash Dominion Period, the Administrative Agent shall apply all funds credited to the Concentration Account the previous Business Day (whether or not immediately available) as follows (except as set forth in Section 5.3(c)): first, to repay the outstanding principal amount of the Swingline Loans and Protective Advances until such Swingline Loans and Protective Advances have been repaid in full; second, to repay the outstanding principal balance of the Loans until such Loans shall have been repaid in full; third, to cash collateralize Letters of Credit Outstanding at one hundred percent (100%) and then to any other Obligation then due and payable.

5.3. Payments Generally.

(a) Except as otherwise specifically provided herein, all payments under this Agreement shall be made by the Borrowers, without set-off, counterclaim or deduction of any kind, to the Administrative Agent for the ratable account of the Lenders entitled thereto, the Letter of Credit Issuer, the Administrative Agent or the Swingline Lender, as the case may be, not later than 12:00 Noon (New York time) on the date when due and shall be made in Dollars in immediately available funds at the Administrative Agent’s Office, it being understood that written or facsimile notice by the Borrowers to the Administrative Agent to make a payment from the funds in the Borrowers’ account at the Administrative Agent’s Office shall constitute the making of such payment to the extent of such funds held in such account. The Administrative Agent will thereafter cause to be distributed on the same day (if payment was actually received by the Administrative Agent prior to 2:00 p.m. (New York time) on such day) like funds relating to the payment of principal or interest or Fees ratably to the Lenders entitled thereto.

(b) Any payments under this Agreement that are made later than 2:00 p.m. (New York time) shall be deemed to have been made on the next succeeding Business Day. Whenever any payment to be made hereunder shall be stated to be due on a day that is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day and, with respect to payments of principal, interest shall be payable during such extension at the applicable rate in effect immediately prior to such extension.

(c) (x) Any proceeds of the sale, transfer or other disposition of Collateral outside of the ordinary course of business received by the Administrative Agent after an Event of Default has occurred and is continuing or (y) any other proceeds of Collateral received by the

-60-

Administrative Agent after an Event of Default specified in Section 11.5 or a termination of the Total Commitment or acceleration of the Obligations under this Agreement pursuant to Section 11 has occurred and is continuing shall in the case of either (x) or (y) be applied ratably first, to pay any fees, indemnities, or expense reimbursements including amounts then due to the Administrative Agent, the Collateral Agent and the Letter of Credit Issuer from the Credit Parties (other than in connection with Secured Cash Management Agreements and Secured Hedge Agreements), second, to pay any fees or expense reimbursements then due to the Lenders from the Credit Parties (other than in connection with Secured Cash Management Agreements and Secured Hedge Agreements), third, to pay interest due in respect of the Protective Advances, fourth, to pay the principal of the Protective Advances, fifth, to pay interest then due and payable on the Loans (other than the Protective Advances) ratably, sixth, to prepay principal on the remaining Loans and Unpaid Drawings, ratably, seventh, to pay an amount to the Administrative Agent equal to one hundred five percent (105%) of the aggregate undrawn face amount of all outstanding Letters of Credit and the aggregate amount of any unpaid Unpaid Drawings, to be held as cash collateral for such Obligations, eighth, to the payment of any amounts owing with respect to Secured Hedge Agreements, ninth, to payment of any amounts owing with respect to Secured Cash Management Agreements, and tenth, to the payment of any other Obligation due to the Administrative Agent or any Secured Party.

(d) At the election of the Administrative Agent, all payments of principal, interest, Unpaid Drawings, Fees, reimbursable expenses (including, without limitation, all reimbursement for fees and expenses pursuant to Section 13.5), and other sums payable under the Credit Documents that are not paid when due in accordance with the Credit Documents (after giving effect to any applicable grace period(s)), may be paid from the proceeds of Borrowings made hereunder whether made following a request by the Borrowers pursuant to Section 2.3 or a deemed request as provided in this Section or may be deducted from any deposit account of the Credit Parties maintained with the Administrative Agent. The Borrowers hereby irrevocably authorize solely to the extent a payment is not paid by a Credit Party by the time when required to be paid, (i) the Administrative Agent to make a Borrowing for the purpose of paying each payment of principal, interest and Fees as it becomes due hereunder or any other amount due under the Credit Documents and agree that all such amounts charged shall constitute Loans (including Swingline Loans, but such a Borrowing may only constitute a Protective Advance if it is to reimburse costs, fees and expenses as described in Section 13.5) and that all such Borrowings shall be deemed to have been requested pursuant to Section 2.3 and (ii) the Administrative Agent to charge any deposit account of any Credit Party maintained with the Administrative Agent for each payment of principal, interest and Fees as it becomes due hereunder or any other amount due under the Credit Documents; provided that in either case the Administrative Agent shall promptly notify the Borrowers of any such Borrowing or charge.

(e) Unless the Administrative Agent shall have received notice from the Borrowers prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Letter of Credit Issuer hereunder that the Borrowers will not make such payment, the Administrative Agent may assume that the Borrowers have made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Letter of Credit Issuer, as the case may be, the amount due. In such event, if the

-61-

Borrowers have not in fact made such payment, then each of the Lenders or the Letter of Credit Issuer, as the case may be, severally (and not jointly) agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Letter of Credit Issuer with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

5.4. Net Payments.

(a) Unless required by a Requirement of Tax Law (as determined in good faith by the Administrative Agent or other applicable withholding agent), all payments made by or on behalf of the Borrowers or any other Credit Party under this Agreement or any other Credit Document shall be made free and clear of, and without deduction or withholding for or on account of, any Taxes. In the event that an applicable withholding agent is required to deduct or withhold any Indemnified Taxes from or in respect of any payment hereunder or under any other Credit Document (as determined in good faith by the applicable withholding agent), then:

(i) the applicable withholding agent shall deduct or withhold the full amount required to be so withheld or deducted;

(ii) the applicable withholding agent shall timely pay such withheld or deducted amounts directly to the relevant Governmental Authority in accordance with the applicable Requirement of Tax Law;

(iii) if a Credit Party is the applicable withholding agent, such Credit Party will promptly forward to the Administrative Agent an official receipt or other documentation satisfactory to the Administrative Agent evidencing such payment to such Governmental Authority; and

(iv) the relevant Credit Party will pay to the Administrative Agent for the account of each affected Lender (which term shall, for the purpose of this Section 5.4, include the Letter of Credit Issuer and any L/C Participant) such additional amount or amounts as are necessary to ensure that the net amount actually received by each such Lender will equal the full amount such Lender would have received had no such withholding or deduction been required.

(b) The Borrowers shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable Requirements of Tax Law, other than any Other Taxes that are Other Connection Taxes arising as a result of a Lender’s voluntary assignment or transfer of, or participation in, such Lender’s right’s or obligations hereunder (“Other Connection Assignment Taxes”).

(c) The Borrowers shall, jointly and severally, indemnify the Administrative Agent and each Lender, within 20 days after demand therefor, for the full amount of any Indemnified Taxes (including any Indemnified Taxes imposed or asserted on or attributable to amounts

-62-

payable under this Section) and Other Taxes paid or payable by the Administrative Agent or such Lender, as the case may be, and any reasonable expenses arising therefrom or with respect thereto, whether or not such any Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrowers by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(d) (1) Any Lender that is entitled to an exemption from, or reduction of, any applicable withholding tax with respect to any payments under any Credit Document shall deliver to RailAmerica and the Administrative Agent, at any time or times reasonably requested by RailAmerica or the Administrative Agent, such properly completed and executed documentation reasonably requested by RailAmerica or the Administrative Agent as will permit such payments to be made without, or at a reduced rate of, withholding. In addition, any Lender, if requested by RailAmerica or the Administrative Agent, shall deliver such other documentation prescribed by law or reasonably requested by RailAmerica or the Administrative Agent as will enable RailAmerica or the Administrative Agent to determine whether or not such Lender is subject to source withholding or backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth below in the following subparagraph (2) of this Section 5.4(d)) shall not be required if in the Lender’s judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. Upon the reasonable request of RailAmerica or the Administrative Agent, any Lender shall update any form or certification previously delivered pursuant to this Section 5.4(d). If any form or certification previously delivered pursuant to this Section 5.4(d) expires or becomes obsolete or inaccurate in any respect with respect to a Lender, such Lender shall promptly (and in any event within 10 days after such expiration, obsolescence or inaccuracy) notify RailAmerica and the Administrative Agent in writing of such expiration, obsolescence or inaccuracy and update the form or certification if it is legally able to do so.

(2) Without limiting the generality of the foregoing, each Non-U.S. Lender shall, to the extent it is legally able to do so:

(i) prior to the date on which a Lender becomes a Lender under this Agreement, deliver to RailAmerica and the Administrative Agent two copies of either (x) in the case of Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest,” Internal Revenue Service Form W-8BEN or any applicable successor form (together with a certificate substantially in the form of Exhibit ▇-▇, ▇-▇, ▇-▇ ▇▇ ▇-▇, as applicable, representing that such Non-U.S. Lender is not a bank for purposes of Section 881(c) of the Code, is not a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of RailAmerica, is not a controlled foreign corporation related to the Borrowers (within the meaning of Section 864(d)(4) of the Code) and that no interest payments in connection with the Credit Documents are effectively connected with such Non-U.S.

-63-

Lender’s conduct of a U.S. trade or business (a “U.S. Tax Certificate”)), (y) Internal Revenue Service Form W-8BEN or Form W-8ECI or any applicable successor form, in each case properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or reduced rate of, U.S. federal withholding tax on payments by any Borrower under any Credit Document or (z) in the case of a Non-U.S. Lender that is not the beneficial owner (for example, where the Non-U.S. Lender is a partnership or participating Lender granting a typical participation), Internal Revenue Service Form W-8IMY, accompanied by a Form W-8ECI, W-8BEN, a U.S. Tax Certificate, Form W-9 and/or other certification documents from each beneficial owner, as applicable; provided that, if the Non-U.S. Lender is a partnership (and not a participating Lender) and one or more beneficial owners of such Non-U.S. Lender are claiming the portfolio interest exemption, such Non-U.S. Lender may provide a Certificate on behalf of such beneficial owner(s); and

(ii) deliver to RailAmerica and the Administrative Agent two further copies of any such form or certification (or any applicable successor form) on or before the date that any such form or certification expires or becomes obsolete, and after the occurrence of any event requiring a change in the most recent form previously delivered by it to RailAmerica and the Administrative Agent.

(e) Each Lender that is a U.S. person within the meaning of Section 7701(a)(30) of the Code shall deliver to RailAmerica and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter as prescribed by applicable law, on or before the date that any such form or certification expires or becomes obsolete, and after the occurrence of any event involving the Lender requiring a change in the most recent form previously delivered by it or upon the request of RailAmerica or the Administrative Agent) duly executed and properly completed copies of Internal Revenue Service Form W-9 or any applicable successor form certifying that it is not subject to backup withholding.

(f) If the Borrowers determine in good faith that a reasonable basis exists for contesting any Indemnified Taxes for which indemnification has been made hereunder, the relevant Lender or the Administrative Agent, as applicable, shall use reasonable efforts to cooperate with the Borrowers in challenging such taxes at the Borrowers’ expense if so requested by the Borrowers in writing; provided that nothing in this Section 5.4(f) shall obligate the Administrative Agent or any Lender to take any action that, in its reasonable judgment, would be materially disadvantageous to such person. If any Lender or the Administrative Agent, as applicable, receives a refund of an Indemnified Tax for which a payment has been made by the Borrowers pursuant to this Agreement, which refund in the sole good faith judgment of such Lender or Administrative Agent, as the case may be, is attributable to such payment made by such Borrowers, then the Lender or the Administrative Agent, as the case may be, shall reimburse the Borrowers for such amount (without interest other than any interest received by the Governmental Authority with respect to such refund) as the Lender or Administrative Agent, as the case may be, determines to be the proportion of the refund as will leave it, after such reimbursement, in no better or worse net after-tax position than it would have been in if the Indemnified Taxes giving rise to

-64-

such refund had not been imposed in the first instance; provided that the Borrowers, upon the request of the Administrative Agent or such Lender, agree to repay the amount paid over to the Borrowers (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. Neither a Lender nor the Administrative Agent shall be obliged to disclose any information regarding its tax affairs or computations to the Borrowers in connection with this paragraph (f) or any other provision of this Section 5.4.

(g) The agreements of any Credit Party in this Section 5.4 shall survive the termination of the Credit Documents and the payment of the Loans and all other amounts payable hereunder.

5.5. Computations of Interest and Fees.

(a) Interest on Eurodollar Loans and, except as provided in the next succeeding sentence, ABR Loans shall be calculated on the basis of a 360-day year for the actual days elapsed. Interest on ABR Loans in respect of which the rate of interest is calculated on the basis of the Prime Rate and interest on overdue interest shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed.

(ii) thereafter, by reducing any fees, commissions, premiums and other amounts required to be paid by the Borrowers to the affected Lender.

Notwithstanding the foregoing, and after giving effect to all adjustments contemplated thereby, if any Lender shall have received from the Borrowers an amount in excess of the maximum permitted by any applicable law, rule or regulation, then the Borrowers shall be entitled, by notice in writing to the Administrative Agent to obtain reimbursement from that Lender in an amount equal to such excess, and pending such reimbursement, such amount shall be deemed to be an amount payable by that Lender to the Borrowers. Any amount or rate of interest referred to in this Section 5.6(c) shall be determined in accordance with generally accepted actuarial practices and principles as an effective annual rate of interest over the term that any Loan remains outstanding.

SECTION 12. The Agents

12.1. Appointment and Authority. Each Lender hereby irrevocably appoints Citicorp North America, Inc. to act on its behalf as the Administrative Agent and as the Collateral Agent hereunder and under the other Credit Documents and authorizes the Agents to take such actions on its behalf and to exercise such powers as are delegated to the Agents by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Agents and the Lenders, and neither the Borrowers nor any other Credit Party shall have rights as a third party beneficiary of any of such provisions.

12.2. Agents Individually.

(a) Each Person serving as an Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include each Person serving as an Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with any Borrower or any Subsidiary or other Affiliate thereof as if such Person were not an Agent hereunder and without any duty to account therefor to the Lenders.

(b) Each Lender understands that each Person serving an Agent, acting in its individual capacity, and its Affiliates (collectively, the “Agent’s Group”) are engaged in a wide range of financial services and businesses (including investment management, financing, securities trading, corporate and investment banking and research) (such services and businesses are collectively referred to in this Section 12 as “Activities”) and may engage in the Activities with or on behalf of one or more of the Credit Parties or their respective Affiliates. Furthermore, the Agent’s Group may, in undertaking the Activities, engage in trading in financial products or undertake other investment businesses for its own account or on behalf of others (including the Credit Parties and their Affiliates and including holding, for its own account or on behalf of others, equity, debt and similar positions in any Borrower, another Credit Party or their respective Affiliates), including trading in or holding long, short or derivative positions in securities, loans or other financial products of one or more of the Credit Parties or their Affiliates. Each Lender understands and agrees that in engaging in the Activities, the Agent’s Group may receive or otherwise obtain information concerning the Credit Parties or their Affiliates (including information concerning the ability of the Credit Parties to perform their respective Obligations hereunder and under the other Credit Documents) which information may not be available to any of the Lenders that are not members of the Agent’s Group. No Agent nor any member of the Agent’s Group shall have any duty to disclose to any Lender or use on behalf of the Lenders, and shall not be liable for the failure to so disclose or use, any information whatsoever about or derived from the Activities or otherwise (including any information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any Credit Party or any Affiliate of any Credit Party) or to account for any revenue or profits obtained in connection with the Activities, except that each Agent shall deliver or otherwise make available to each Lender such

-101-

documents as are expressly required by any Credit Document to be transmitted by such Agent to the Lenders.

(c) Each Lender further understands that there may be situations where members of the Agent’s Group or their respective customers (including the Credit Parties and their Affiliates) either now have or may in the future have interests or take actions that may conflict with the interests of any one or more of the Lenders (including the interests of the Lenders hereunder and under the other Credit Documents). Each Lender agrees that no member of the Agent’s Group is or shall be required to restrict its activities as a result of each Person serving as an Agent being a member of the Agent’s Group, and that each member of the Agent’s Group may undertake any Activities without further consultation with or notification to any Lender. None of (i) this Agreement nor any other Credit Document, (ii) the receipt by the Agent’s Group of information (including Information) concerning the Credit Parties or their Affiliates (including information concerning the ability of the Credit Parties to perform their respective Obligations hereunder and under the other Credit Documents) nor (iii) any other matter shall give rise to any fiduciary, equitable or contractual duties (including without limitation any duty of trust or confidence) owing by the any Agent or any member of the Agent’s Group to any Lender including any such duty that would prevent or restrict the Agent’s Group from acting on behalf of customers (including the Credit Parties or their Affiliates) or for its own account.

12.3. Duties of the Agents; Exculpatory Provisions.

(a) Each Agent’s duties hereunder and under the other Credit Documents are solely ministerial and administrative in nature and no Agent shall have any duties or obligations except those expressly set forth herein and in the other Credit Documents. Without limiting the generality of the foregoing, no Agent shall have any duty to take any discretionary action or exercise any discretionary powers, but shall be required to act or refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the written direction of the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Credit Documents), provided that no Agent shall be required to take any action that, in its opinion or the opinion of its counsel, may expose such Agent or any of its Affiliates to liability or that is contrary to any Credit Document or applicable law.

(b) No Agent shall be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as such Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 13.1 or 11) or (ii) in the absence of its own gross negligence or willful misconduct. Each Agent shall be deemed not to have knowledge of any Default or Event of Default or the event or events that give or may give rise to any Default or Event of Default unless and until the Borrowers or any Lender shall have given notice to such Agent describing such Default or Event of Default and such event or events.

(c) No Agent nor any member of the Agent’s Group shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty, representation or other information made or supplied in or in connection with this Agreement or any other Credit Document, (ii) the contents of any certificate, report or other document delivered hereunder or

-102-

thereunder or in connection herewith or therewith or the adequacy, accuracy and/or completeness of the information contained therein, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Credit Document or any other agreement, instrument or document or the perfection or priority of any Lien or security interest created or purported to be created by the Collateral Documents or (v) the satisfaction of any condition set forth in Sections 6 and 7 or elsewhere herein, other than (but subject to the foregoing clause (ii)) to confirm receipt of items expressly required to be delivered to such Agent.

(d) Nothing in this Agreement or any other Credit Document shall require any Agent or any of its Related Parties to carry out any “know your customer” or other checks in relation to any person on behalf of any Lender and each Lender confirms to each Agent that it is solely responsible for any such checks it is required to carry out and that it may not rely on any statement in relation to such checks made by such Agent or any of its Related Parties.

12.4. Reliance by Agents. Each Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. Each Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender unless an officer of the Administrative Agent responsible for the transactions contemplated hereby shall have received notice to the contrary from such Lender prior to the making of such Loan or the issuance of such Letter of Credit, and in the case of a Borrowing, such Lender shall not have made available to the Administrative Agent such Lender’s ratable portion of such Borrowing. Each Agent may consult with legal counsel (who may be counsel for the Borrowers or any other Credit Party), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. No Agent shall be deemed to have knowledge of any Secured Cash Management Agreement or any Secured Hedge Agreement unless and until it has received written notice thereof from the applicable Hedge Bank or Cash Management Bank.

12.5. Delegation of Duties. Each Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Credit Document by or through any one or more sub-agents appointed by such Agent. Each Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. Each such sub-agent and the Related Parties of such Agent and each such sub-agent shall be entitled to the benefits of all provisions of this Section 12 and Section 13.5 (as though such sub-agents were the “Administrative Agent” or “Collateral Agent” under the Credit Documents) as if set forth in full herein with respect thereto.

-103-

12.6. Resignation of Agents.

(a) Each Agent may at any time give notice of its resignation to the Lenders and RailAmerica. Upon receipt of any such notice of resignation, the Required Lenders shall have the right to appoint a successor, which shall be a bank with an office in New York City, or an Affiliate of any such bank with an office in New York City and which successor shall be subject to the approval of RailAmerica (not to be unreasonably withheld or delayed) unless an Event of Default has occurred and is continuing. If no such successor shall have been so appointed by the Required Lenders in accordance with the foregoing sentence and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation (such 30-day period, the “Lender Appointment Period”), then the retiring Agent may on behalf of the Lenders, appoint a successor Agent meeting the qualifications set forth above. In addition and without any obligation on the part of the retiring Agent to appoint, on behalf of the Lenders, a successor Agent, the retiring Agent may at any time upon or after the end of the Lender Appointment Period notify the Borrowers and the Lenders that no qualifying Person has accepted appointment as successor Agent and the effective date of such retiring Agent’s resignation which effective date shall be no earlier than three business days after the date of such notice. Upon the resignation effective date established in such notice and regardless of whether a successor Agent has been appointed and accepted such appointment, the retiring Agent’s resignation shall nonetheless become effective and (i) the retiring Agent shall be discharged from its duties and obligations as Agent hereunder and under the other Credit Documents and (ii) all payments, communications and determinations provided to be made by, to or through an Agent shall instead be made by or to each Lender directly, until such time as the Required Lenders appoint a successor Agent as provided for above in this paragraph. Upon the acceptance of a successor’s appointment as Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties as Agent of the retiring (or retired) Agent, and the retiring Agent shall be discharged from all of its duties and obligations as Agent hereunder or under the other Credit Documents (if not already discharged therefrom as provided above in this paragraph). The fees payable by the Borrowers to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor. After the retiring Agent’s resignation hereunder and under the other Credit Documents, the provisions of this Article and Section 13.5 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Agent was acting as Agent.

(b) Any resignation pursuant to this Section by a Person acting as Administrative Agent shall, unless such Person shall notify the Borrowers and the Lenders otherwise, also act to relieve such Person and its Affiliates of any obligation to advance or issue new, or extend existing, Swingline Loans or Letters of Credit where such advance, issuance or extension is to occur on or after the effective date of such resignation. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, (i) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Letter of Credit Issuer and Swingline Lender, (ii) the retiring Letter of Credit Issuer and Swingline Lender shall be discharged from all of their respective duties and obligations hereunder or under the other Credit Documents, (iii) the successor Swingline Lender shall enter into an Assignment and Assumption

-104-

and acquire from the retiring Swingline Lender each outstanding Swingline Loan of such retiring Swingline Lender for a purchase price equal to par plus accrued interest and (iv) the successor Letter of Credit Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangement satisfactory to the retiring Letter of Credit Issuer to effectively assume the obligations of the retiring Letter of Credit Issuer with respect to such Letters of Credit.

In addition to the foregoing, if a Lender becomes, and during the period it remains, a Defaulting Lender or a Potential Defaulting Lender, the Letter of Credit Issuer and/or the Swingline Lender may, upon prior written notice to RailAmerica and the Administrative Agent, resign as Letter of Credit Issuer or Swingline Lender, respectively, effective at the close of business New York time on a date specified in such notice (which date may not be less than five (5) Business Days after the date of such notice); provided that such resignation by the Letter of Credit Issuer will have no effect on the validity or enforceability of any Letter of Credit then outstanding or on the obligations of the Borrowers or any Lender under this Agreement with respect to any such outstanding Letter of Credit or otherwise to the Letter of Credit Issuer; and provided, further, that such resignation by the Swingline Lender will have no effect on its rights in respect of any outstanding Swingline Loans or on the obligations of the Borrowers or any Lender under this Agreement with respect to any such outstanding Swingline Loan.

Anything herein to the contrary notwithstanding, if at any time the Required Lenders determine that the Person serving as Administrative Agent is (without taking into account any provision in the definition of “Defaulting Lender” or “Potential Defaulting Lender” requiring notice from the Administrative Agent or any other party) a Defaulting Lender or a Potential Defaulting Lender, subject to the prior approval of RailAmerica (not to be unreasonably withheld or delayed) with respect to the appointment of the replacement Administrative Agent if no Event of Default has occurred and is continuing, the Required Lenders (determined after giving effect to Section 13.1(c), may by notice to such Person remove such Person as Administrative Agent and appoint a replacement Administrative Agent hereunder. Such removal will, to the fullest extent permitted by applicable law, be effective on the earlier of (i) the date a replacement Administrative Agent is appointed and (ii) the date 30 Business Days after the giving of such notice by the Required Lenders (regardless of whether a replacement Administrative Agent has been appointed). Unless otherwise agreed by the Required Lenders (and, if no Event of Default has occurred and is continuing, with the approval of RailAmerica (not to be unreasonably withheld or delayed)), upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Letter of Credit Issuer and Swingline Lender.

12.7. Non-Reliance on Agent and Other Lenders.

(a) Each Lender confirms to each Agent, each other Lender and each of their respective Related Parties that it (i) possesses (individually or through its Related Parties) such knowledge and experience in financial and business matters that it is capable, without reliance on any Agent, any other Lender or any of their respective Related Parties, of evaluating the merits and risks (including tax, legal, regulatory, credit, accounting and other financial matters) of (x)

-105-

entering into this Agreement, (y) making Loans and other extensions of credit hereunder and under the other Credit Documents and (z) in taking or not taking actions hereunder and thereunder, (ii) is financially able to bear such risks and (iii) has determined that entering into this Agreement and making Loans and other extensions of credit hereunder and under the other Credit Documents is suitable and appropriate for it.

(b) Each Lender acknowledges that (i) it is solely responsible for making its own independent appraisal and investigation of all risks arising under or in connection with this Agreement and the other Credit Documents, (ii) that it has, independently and without reliance upon any Agent, any other Lender or any of their respective Related Parties, made its own appraisal and investigation of all risks associated with, and its own credit analysis and decision to enter into, this Agreement based on such documents and information, as it has deemed appropriate and (iii) it will, independently and without reliance upon any Agent, any other Lender or any of their respective Related Parties, continue to be solely responsible for making its own appraisal and investigation of all risks arising under or in connection with, and its own credit analysis and decision to take or not take action under, this Agreement and the other Credit Documents based on such documents and information as it shall from time to time deem appropriate, which may include, in each case:

(i) the financial condition, status and capitalization of the Borrowers and each other Credit Party;

(ii) the legality, validity, effectiveness, adequacy or enforceability of this Agreement and each other Credit Document and any other agreement, arrangement or document entered into, made or executed in anticipation of, under or in connection with any Credit Document;

(iii) determining compliance or non-compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit and the form and substance of all evidence delivered in connection with establishing the satisfaction of each such condition;

(iv) the adequacy, accuracy and/or completeness of any information delivered by any Agent, any other Lender or by any of their respective Related Parties under or in connection with this Agreement or any other Credit Document, the transactions contemplated hereby and thereby or any other agreement, arrangement or document entered into, made or executed in anticipation of, under or in connection with any Credit Document.

12.8. No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the Persons acting as Sole Lead Arranger or Sole Bookrunner listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Credit Documents, except in its capacity, as applicable, as the Administrative Agent, the Collateral Agent or as a Lender hereunder.

12.9. Withholding Tax. To the extent required by any applicable law, the Administrative Agent may withhold from any payment to any Lender an amount equivalent to

-106-

any applicable withholding tax. If the Internal Revenue Service or any authority of the United States or other jurisdiction asserts a claim that the Administrative Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered, was not properly executed, or because such Lender failed to notify the Administrative Agent of a change in circumstances which rendered the exemption from, or reduction of, withholding tax ineffective, or for any other reason), such Lender shall indemnify the Administrative Agent fully for all amounts paid, directly or indirectly, by the Administrative Agent as tax or otherwise, including penalties and interest, together with all expenses incurred, including legal expenses, and any out of pocket expenses. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under this Agreement or any other Credit Document against any amount due the Administrative Agent under this Section 12.9. The agreements in this Section 12.9 shall survive the resignation and/or replacement of the Administrative Agent, any assignment of rights by, or the replacement of, a Lender, and the repayment, satisfaction or discharge of any Loans and all other amounts payable any Credit Document.

12.10. Reports. Each Lender hereby agrees that (a) it has requested a copy of each Report prepared by or on behalf of any Agent; (b) the Agents (i) make no representation or warranty, express or implied, as to the completeness or accuracy of any Report or any of the information contained therein or any inaccuracy or omission contained in or relating to a Report and (ii) shall not be liable for any information contained in any Report; (c) the Reports are not comprehensive audits or examinations, and that any Person performing any field examination will inspect only specific information regarding the Credit Parties and will rely significantly upon the Credit Parties’ books and records, as well as on representations of the Credit Parties’ personnel and that the Agents undertake no obligation to update, correct or supplement the Reports; (d) it will keep all Reports confidential and strictly for its internal use, not share the Report with any other Person except as otherwise permitted pursuant to this Agreement; and (e) without limiting the generality of any other indemnification provision contained in this Agreement, it will pay and protect, and indemnify, defend, and hold each Agent and any such other Person preparing a Report harmless from and against, the claims, actions, proceedings, damages, costs, expenses, and other amounts (including reasonable attorney fees) incurred by as the direct or indirect result of any third parties who might obtain all or part of any Report through the indemnifying Lender.

12.11. Indemnification. The Lenders agree to indemnify each Agent, in its capacity as such (to the extent not reimbursed by the Borrowers and without limiting the obligation of the Borrowers to do so), ratably according to their Applicable Percentage in effect on the date on which indemnification is sought (or, if indemnification is sought after the date upon which the Commitments shall have terminated and the Total Credit Exposure shall have been paid in full, ratably in accordance with their respective portions of the Total Credit Exposure in effect immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (including at any time following the payment of the Loans) be imposed on, incurred by or asserted against any Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Credit Documents or any documents contemplated by or

-107-

referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by any Agent under or in connection with any of the foregoing, provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements to an Agent resulting from such Agent’s gross negligence or willful misconduct (as determined in a final non-appealable judgment by a court of competent jurisdiction). The agreements in this Section 12.11 shall survive the payment of the Loans and all other amounts payable hereunder.

SECTION 13. Miscellaneous

Additionally, the Administrative Agent is hereby authorized in its sole discretion to release any Liens as required to effect any sale or other disposition of such Collateral in connection with any exercise of remedies of the Administrative Agent and the Lenders pursuant to Section 11. In connection with any release of Liens under the Security Documents, the Administrative Agent shall be protected in relying on a certificate of an Authorized Officer to the effect that such release is permitted by this Section 13.1(b).

(c) Anything herein to the contrary notwithstanding, during such period as a Lender is a Defaulting Lender, to the fullest extent permitted by applicable law, such Lender will not be entitled to vote in respect of amendments and waivers hereunder and the Commitment and the outstanding Loans or other extensions of credit of such Lender hereunder will not be taken into account in determining whether the Required Lenders or all of the Lenders, as required, have approved any such amendment or waiver (and the definition of “Required Lenders” will automatically be deemed modified accordingly for the duration of such period); provided, that any such amendment or waiver that would increase or extend the term of the Commitment of such Defaulting Lender, extend the date fixed for the payment of principal or interest owing to such Defaulting Lender hereunder, reduce the principal amount of any obligation owing to such Defaulting Lender, reduce the amount of or the rate or amount of interest on any amount owing to such Defaulting Lender or of any fee payable to such Defaulting Lender hereunder, or alter the terms of this proviso, will require the consent of such Defaulting Lender

13.3. No Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising, on the part of the Administrative Agent or any Lender, any right, remedy, power or privilege hereunder or under the other Credit Documents shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

13.6. Successors and Assigns; Participations and Assignments.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Letter of Credit Issuer that issues any Letter of Credit), except that (i) no Borrower may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by any Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Letter of Credit Issuer that issues any Letter of Credit), Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Letter of Credit Issuer and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under

-112-

this Agreement (including all or a portion of its Commitments and the Loans at the time owing to it) with the prior written consent (such consent not be unreasonably withheld) of:

(A) RailAmerica, provided that no consent of RailAmerica shall be required for an assignment to a Lender, an Affiliate of a Lender or, if an Event of Default has occurred and is continuing, any other assignee;

(B) the Administrative Agent, the Swingline Lender and the Letter of Credit Issuer; and

(C) provided however; that notwithstanding the foregoing or any other provision of this Agreement, in no event shall either Borrower or any of their Subsidiaries be permitted to be a Lender or a Participant hereunder.

(ii) Assignments shall be subject to the following additional conditions:

(A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 and integral multiples of $1,000,000 in excess thereof, or if less, all of such Lender’s remaining Loans and Commitments unless RailAmerica and the Administrative Agent otherwise consents, provided that no such consent of RailAmerica shall be required if an Event of Default has occurred and is continuing; provided further that contemporaneous assignments to a single assignee made by Affiliates of a Lender shall be aggregated for purposes of meeting the minimum assignment amount requirements stated above;

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement;

(C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $3,500; and

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire in a form approved by the Administrative Agent (the “Administrative Questionnaire”).

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(v) of this Section, from and after the effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an

-113-

Assignment and Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.10, 2.11, 3.5, 5.4 and 13.5). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 13.6 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(iv) The Administrative Agent, acting solely for this purpose as an agent of the Borrowers, shall maintain at the Administrative Agent’s Office a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amount (and stated interest) of the Loans and any payment made by the Letter of Credit Issuer under any Letter of Credit owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrowers, the Administrative Agent, the Letter of Credit Issuer and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrowers, the Letter of Credit Issuer and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Acceptance and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c) (i) Any Lender may, without the consent of the Borrowers, the Administrative Agent, the Letter of Credit Issuer or the Swingline Lender, sell participations to one or more banks or other entities (each, a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans owing to it), provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrowers, the Administrative Agent, the Letter of Credit Issuer and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement or any other Credit Document, provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 13.1(a) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrowers agree that each Participant shall be entitled to the benefits of Sections 2.10, 2.11, 3.5 and

-114-

5.4 (subject to the requirements of such Sections) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 13.8(b) as though it were a Lender, provided such Participant agrees to be subject to Section 13.8(a) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.10 or 5.4 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with RailAmerica’s prior written consent (not to be unreasonably withheld or delayed);

(iii) Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under this Agreement (the “Participant Register”). The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. Any such Participant Register shall be available for inspection by the Administrative Agent or RailAmerica (and if required by applicable Requirement of Tax Law or in connection with a Tax audit or any Borrower, the Borrowers) at any reasonable time and from time to time upon reasonable prior notice.

(d) Any Lender may, without the consent of the Borrowers or the Administrative Agent, at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest, provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. In order to facilitate such pledge or assignment, the Borrowers hereby agree that, upon request of any Lender at any time and from time to time after the Borrowers have made their initial Borrowing hereunder, the Borrowers shall provide to such Lender, at the Borrowers’ own expense, a promissory note, substantially in the form of Exhibit K, as the case may be, evidencing the Revolving Credit Loans and Swingline Loans, respectively, owing to such Lender.

(e) Subject to compliance with Section 13.16, the Borrowers authorize each Lender to disclose to any Participant, secured creditor of such Lender or assignee (each, a “Transferee”) and any prospective Transferee any and all Information (including any and all financial information) in such Lender’s possession concerning the Borrowers and the Restricted Subsidiaries that has been delivered to such Lender by or on behalf of the Borrowers and the Restricted Subsidiaries pursuant to this Agreement or which has been delivered to such Lender by or on behalf of the Borrowers and the Restricted Subsidiaries in connection with such Lender’s credit evaluation of the Borrowers and the Restricted Subsidiaries prior to becoming a party to this Agreement.

-115-

13.7. Replacements of Lenders under Certain Circumstances. The Borrower shall be permitted to replace any Lender that (a) requests reimbursement for amounts owing pursuant to Section 2.10, 2.12, 3.5 or 5.4, (b) is affected in the manner described in Section 2.10(a)(iii) and as a result thereof any of the actions described in such Section is required to be taken, (c) becomes a Defaulting Lender, with a replacement bank or other financial institution or (d) in connection with any proposed amendment, waiver or consent requiring the consent of “each Lender” or “each Lender affected thereby” pursuant to Section 13.1(a), does not consent when the consent of the Required Lenders has been obtained, but the consent of other remaining Lenders has not been obtained, provided that (i) such replacement does not conflict with any Requirement of Law, (ii) no Event of Default shall have occurred and be continuing at the time of such replacement, (iii) the Borrowers shall repay (or the replacement bank or institution shall purchase, at par) all Loans and other amounts (other than any disputed amounts), pursuant to Section 2.8, 2.10, 2.11, 2.13, 3.3, 3.5, 4.1, 5.4 or 13.5, as the case may be, owing to such replaced Lender prior to the date of replacement, (iv) the replacement bank or institution, if not already a Lender, and the terms and conditions of such replacement, shall be reasonably satisfactory to the Administrative Agent, (v) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 13.6 (provided that the Borrowers shall be obligated to pay the registration and processing fee referred to therein) and (vi) any such replacement shall not be deemed to be a waiver of any rights that the Borrowers, the Administrative Agent, the Collateral Agent or any other Lender shall have against the replaced Lender.

13.8. Adjustments; Set-off.

(a) If any Lender (a “Benefited Lender”) shall at any time receive any payment of all or part of its Loans, or interest thereon, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 11.5, or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of such other Lender’s Loans, or interest thereon, such benefited Lender shall purchase for cash from the other Lenders a participating interest in such portion of each such other Lender’s Loan, or shall provide such other Lenders with the benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such benefited Lender to share the excess payment or benefits of such collateral or proceeds ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

(b) After the occurrence and during the continuance of an Event of Default, in addition to any rights and remedies of the Lenders provided by law, each Lender shall have the right, without prior notice to the Borrowers, any such notice being expressly waived by the Borrowers to the extent permitted by applicable law, upon any amount becoming due and payable by the Borrowers hereunder (whether at the stated maturity, by acceleration or otherwise) to set-off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or

-116-

unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of the Borrowers. Each Lender agrees promptly to notify the Borrowers and the Administrative Agent after any such set-off and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such set-off and application.

13.9. Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by facsimile or other electronic transmission), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. A set of the copies of this Agreement signed by all the parties shall be lodged with the Borrowers and the Administrative Agent.

13.10. Severability. Any provision of any Credit Document that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

13.11. Integration. This Agreement and the other Credit Documents represent the agreement of the Borrowers, the Administrative Agent, the Collateral Agent and the Lenders with respect to the subject matter hereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent, the Collateral Agent or any Lender relative to subject matter hereof not expressly set forth or referred to herein or in the other Credit Documents.

13.12. GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.
