(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 make available to the Borrowers, by depositing to RailAmerica’s account designated in the Notice of Borrowing/Continuation (on behalf of the Borrowers) 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

-43-

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 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 Initial Lenders, on the Initial Maturity Date, the then-unpaid Initial Loans.

(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 and the Type and Class 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 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

-44-

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 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, (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 Loans to be so converted or continued, the Type and Class of Loans to be converted or continued into and, if such 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 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. 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.

-45-

2.8. Interest.

(a) The unpaid principal amount of each ABR Loan shall bear interest from the date of the Borrowing thereof until maturity (whether by acceleration or otherwise) at a rate per annum that shall at all times be the ABR Margin plus the ABR in effect from time to time.

(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 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 prior to the applicable Maturity Date thereof), 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/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

-46-

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 or six month period or, if agreed to by each Lender and the Administrative Agent (in its capacity as such), 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;

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

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

-47-

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); provided further that it is understood and agreed that, for the purposes of this Section 2.10(a)(ii), (x) the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act and all requests, rules, guidelines, requirements and directives thereunder, issued in connection therewith or in implementation thereof and (y) all requests, rules, guidelines, requirements and directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III, shall in each case be deemed to be a change in law regardless of the date enacted, adopted, issued or implemented); or

(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/Continuation 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

-48-

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 clauses (ii), (iii) or (iv) 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).

(c) If, after the Closing Date, 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 (it is understood and agreed that, for the purposes of this Section 2.10(c), (i) the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act and all requests, rules, guidelines, requirements and directives thereunder, issued in connection therewith or in implementation thereof, and (ii) all requests, rules, guidelines, requirements and directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III, shall in each case be deemed to be a change in law regardless of the date enacted, adopted, issued or implemented), 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

-49-

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 Section 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/Continuation, (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) or 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 or 5.4.

2.13. Notice of Certain Costs.

Notwithstanding anything in this Agreement to the contrary, to the extent any notice required by Sections 2.10, 2.11 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 Sections 2.10, 2.11 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.

-50-

2.14. Amortization.

(a) The Borrowers shall pay to the Administrative Agent, for the ratable account of the Initial Lenders, on the dates set forth below or, if any such date is not a Business Day, on the immediately preceding Business Day (each such date, a “Initial Loan Repayment Date”) a principal amount in respect of the Initial Loans equal to (x) the aggregate principal amount of Initial Loans made to the Borrowers on the Closing Date multiplied by (y) the percentage set forth below opposite such Initial Loan Repayment Date (each, an “Initial Loan Repayment Amount”), as each such Initial Loan Repayment Amount may be reduced pursuant to the other terms hereof:

2.15. Incremental Facilities.

(a) The Borrowers may by written notice to the Administrative Agent elect to request, prior to the Latest Maturity Date, additional term loans hereunder (any such additional term loans, the “Incremental Loans” and the commitments therefor, the “Incremental Commitments”) in an aggregate principal amount (x) for all such additional term loans not in excess of $150.0 million and (y) on any Incremental Closing Date, not less than, unless otherwise approved by the Administrative Agent, the higher of (I) $25.0 million and (II) any integral multiple of $5.0 million in excess of $25.0 million. Each such notice shall specify (A) the date (each, an “Incremental Closing Date”) on which the Borrowers propose that the Incremental Loans shall be made, which shall be a date not less than 10 Business Days (or such lesser number of days as may be acceptable to the Administrative Agent) 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) to whom the Borrowers propose any portion of such Incremental Commitments be allocated (each, an “Incremental Lender”) and the amounts of such allocations; provided that (i) no Incremental Lender that is not an existing Lender, an Affiliate of a Lender or an Approved Fund shall provide Incremental Loans unless the Administrative Agent shall have consented thereto (such consent not to be unreasonably withheld or delayed), (ii) any Affiliated Lender providing an Incremental Loan shall be subject to the same restrictions set forth in Section 13.6(f),(g) and (h) as it would otherwise be subject to with respect to any purchase by or assignment to such Affiliated Lender of Loans and (iii) any Lender approached to provide all or a portion of any Incremental Loans may elect or decline, in its sole discretion, to provide such Incremental Loans.

-52-

date of such Incremental Closing Date (except where such representations and warranties expressly relate to an earlier date, in which case such representations and warranties shall have been true and correct in all material respects (except that any representation and warranty that is qualified as to “materiality” or “Material Adverse Effect” shall be true and correct in all respects) as of such earlier date); provided that, if the proceeds of such Incremental Loans are used to consummate a Permitted Acquisition, the only representations and warranties that shall be required to be true and correct are those set forth in Sections 8.2. 8.3, 8.5, 8.7, 8.16, 8.20 (provided that the target of such Permitted Acquisition shall be subject to Section 9.10), 8.21 and 8.23; (3) the Incremental Loans shall be effected pursuant to one or more Joinder Agreements executed and delivered by the Borrowers, the Incremental Lenders and the 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); (4) the Credit Parties shall deliver or cause to be delivered any legal opinions or other documents (including without limitation guarantee and collateral reaffirmation agreements) reasonably requested by Administrative Agent in connection with any such transaction; (5) the Consolidated Senior Secured Net Debt to Consolidated EBITDA Ratio as of the Incremental Closing Date after giving effect to the Incremental Loans on a Pro Forma Basis (but without counting any cash or Permitted Investments representing proceeds of such Incremental Loans in calculating clause (y) of the definition of Consolidated Senior Secured Net Debt) shall be less than or equal to 4.0 to 1.0; (6) the maturity date of such Incremental Loans shall be no earlier than the Initial Loan Maturity Date; (7) the Weighted Average Life to Maturity of such Incremental Loans shall be no shorter than the Weighted Average Life to Maturity, as of such Incremental Closing Date, of the Initial Loans outstanding as of such Incremental Closing Date; (8) the All-In Yield of the Incremental Loans shall be determined by the Borrowers and the applicable Incremental Lenders (provided that the All-In Yield applicable to such Incremental Loans shall not be greater than the All-In Yield for the Initial Loans plus 50 basis points per annum unless the ABR Margin and the Eurodollar Margin are increased so as to cause the All-In Yield for the Initial Loans to equal the All-In Yield for such Incremental Loans minus 50 basis points per annum); (9) such Incremental Loans shall be secured by a pari passu lien on the Collateral securing the Loans and shall be guaranteed by all of the Subsidiary Guarantors; and (10) such Incremental Loans shall be on terms and pursuant to a fully executed Joinder Agreement (provided that, to the extent such terms and documentation are not consistent with the existing Credit Documents (except to the extent permitted by clause (6), (7) or (8) above), they shall be reasonably satisfactory to the Administrative Agent).

The Incremental Commitment and Incremental Loans established pursuant to this Section shall be entitled to all the benefits afforded by, this Agreement and the other Credit Documents, and shall, without limiting the foregoing, benefit equally and ratably from the Guarantees and security interests

-53-

created by the Security Documents. The Administrative Agent, the Collateral Agent and the Credit Parties (without the consent any Lender that would otherwise be required under Section 13.1) may effect such amendments to this Agreement and the other Credit Documents as may be necessary or appropriate, in the opinion of the Administrative Agent, to effectuate the provisions of this Section 2.15.

2.16. Defaulting Lenders.

(a) Payments. 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 2.16(d)) 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 post-default interest and then current interest due and payable to the Lenders hereunder other than Defaulting Lenders, ratably among them in accordance with the amounts of such interest then due and payable to them, third 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, fourth to pay principal amounts 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, fifth to the ratable payment of other amounts then due and payable to the Non-Defaulting Lenders that are Lenders, and sixth 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) Fees. Anything herein to the contrary notwithstanding, if a Lender becomes, and during the period it remains, 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).

(c) 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 2.16(a) will apply to all amounts thereafter paid by the Borrowers for the account of such Defaulting Lender (whether on account of principal, interest, fees, indemnity payments or other amounts), provided that such termination will not be deemed to be a waiver or release of any claim the Borrowers and the Administrative Agent may have against such Defaulting Lender.

(d) Cure. If the Borrowers and the Administrative Agent 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

-54-

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 2.16(a)), such Lender will comply with its funding obligations hereunder as the Administrative Agent may determine to be necessary, whereupon such Lender will cease to be a Defaulting Lender or Potential Defaulting Lender and will be a Non-Defaulting Lender; 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.

SECTION 3. Extensions/Refinancings.

3.1. Extensions.

(a) The Borrowers may at any time, and from time to time, request that all or a portion of the Loans of any Class (an “Existing Class”) be converted to extend the scheduled maturity date(s) of any payment of principal with respect to all or a portion of any principal amount of such Existing Class (any such Loans which have been so converted, “Extended Loans”) and to provide for other terms consistent with this Section 3.1. In order to establish any Extended Loans, RailAmerica shall provide a notice to the Administrative Agent (who shall provide a copy of such notice to each of the Lenders of such Existing Class) (a “Loan Extension Request”) setting forth the proposed terms of the Extended Loans to be established, which shall (I) be identical as offered to each Lender under such Existing Class (including as to the proposed interest rates and fees payable) and offered pro rata to each Lender under such Existing Class and (II) be identical to the Loans of the Existing Class from which they are to be converted except (w) the scheduled final maturity date shall be extended and any or all of the scheduled amortization payments of the aggregate principal amount of the Extended Loans may be delayed to later dates than the scheduled amortization of principal of such Existing Class (with any such delay resulting in a corresponding adjustment to the scheduled amortization payments reflected in Section 2.14 or in the applicable Extension Amendment, as the case may be, with respect to the Existing Class from which such Extended Loans were converted, in each case as more particularly set forth in Section 3.1(b) below), (x) (A) the Eurodollar Margin and the ABR Margin with respect to the Extended Loans may be higher or lower than the Eurodollar Margin and the ABR Margin for the Existing Class (or another interest rate mechanism or other interest rates for such Extended Loans may be agreed to by the Lenders providing the Extended Loans and the Borrowers) and/or (B) additional fees (including original issue discount and upfront fees) may be payable to the Lenders providing such Extended Loans in addition to or in lieu of any increased margins contemplated by the preceding clause (A), in each case, to the extent provided in the applicable Extension Amendment, (y) Extended Loans may have call protection as may be agreed by the Borrowers and the Lenders thereof and (z) the Extension Amendment relating to such Extended Loans may provide for other covenants and terms applicable to such Extended Loans that apply solely to any period after the Latest Maturity Date that is in effect on the effective date of the Extension Amendment (immediately prior to the establishment of such Extended Loans);

-55-

provided that (i) any Extended Loans may participate in any voluntary or mandatory repayments or prepayments hereunder on a pro rata basis or less than a pro rata basis (but not greater than a pro rata basis) with respect to the Loans of the Existing Class from which they are to be converted, in each case as specified in the respective Loan Extension Request; (ii) no Default shall have occurred and be continuing at the time an Extension Amendment becomes effective; (iii) the Weighted Average Life to Maturity of any Extended Loans of a given Extension Series at the time of establishment thereof shall be no shorter (other than by virtue of amortization or prepayment of such Indebtedness prior to the time of incurrence of such Extended Loans) than the Weighted Average Life to Maturity, as of the date of the Extension Amendment relating to such Extended Loans, of the Existing Class; (iv) in no event shall the final maturity date of any Extended Loans of a given Extension Series at the time of establishment thereof be earlier than the then Latest Maturity Date of any other Class of Loans hereunder; (v) any such Extended Loans (and the Liens securing the same) shall be permitted by the terms of the Intercreditor Agreement (to the extent the Intercreditor Agreement is then in effect); (vi) at no time shall there be Classes of Loans hereunder (including Incremental Loans, Extended Loans and Refinancing Loans) that have more than six (6) different maturity dates; and (vii) all documentation in respect of such Extension Amendment shall be consistent with the foregoing. Any Extended Loans amended pursuant to any Extension Amendment shall be designated a separate Extension Series of Extended Loans for all purposes of this Agreement; provided that any Extended Loans may, to the extent provided in the applicable Extension Amendment, be designated as an increase in any previously established Class of Loans that has a later maturity date than the Loans of the Existing Class from which such Loans are being extended. No Lender shall have any obligation to agree to have any of its Loans converted into Extended Loans pursuant to any Loan Extension Request.

(b) RailAmerica shall provide the applicable Loan Extension Request at least five (5) Business Days prior to the date on which Lenders of the Existing Class (the “Existing Lenders”) are requested to respond. Any Lender (an “Extending Lender”) wishing to have all or a portion of its Existing Class of Loans subject to such Loan Extension Request converted into Extended Loans shall notify the Administrative Agent (an “Extension Election”) on or prior to the date specified in such Loan Extension Request of the amount of its Existing Class of Loans subject to such Loan Extension Request that it has elected to convert into Extended Loans; provided that if any Existing Lenders fail to respond, such Existing Lenders will be deemed to have declined to extend their Loans. In the event that the aggregate amount of Loans subject to Extension Elections exceeds the amount of Extended Loans requested pursuant to the Loan Extension Request, the Existing Class of Loans subject to Extension Elections shall be converted to Extended Loans on a pro rata basis based on the amount of the Existing Class of Loans included in each such Extension Election.

(c) Extended Loans shall be established pursuant to an amendment (an “Extension Amendment”) to this Agreement (which, notwithstanding anything to the contrary set forth in Section 13.1, shall not require the consent of any Lender other than the Extending Lenders with respect to the Extended Loans established thereby) executed by the Credit Parties, the Administrative Agent and the Extending Lenders. No Extension Amendment shall provide for any tranche of Extended Loans in an aggregate principal amount that is less than $25,000,000 (unless the Administrative Agent shall agree to a lesser amount). In addition to any terms and changes required or permitted by Section 3.1(a), each Extension Amendment (x) shall amend the

-56-

scheduled amortization payments pursuant to Section 2.14 or the applicable Joinder Agreement with respect to the Existing Class from which the Extended Loans were converted to reduce each scheduled amortization payment for the Existing Class in the same proportion as the amount of Existing Class that shall have been converted pursuant to such Extension Amendment; (y) may, but shall not be required to, impose additional requirements (not inconsistent with the provisions of this Agreement in effect at such time) with respect to the final maturity and Weighted Average Life to Maturity of Incremental Loans incurred following the date of such Extension Amendment. Notwithstanding anything to the contrary in this Section 3.1 and without limiting the generality or applicability of Section 13.1 to any Section 3.1 Additional Amendments (as defined below) or any of the consents or votes of the Required Lenders, all affected Lenders or all Lenders that may be required pursuant to Section 13.1, any Extension Amendment may provide for additional terms and/or additional amendments other than those referred to or contemplated above (any such additional amendment, a “Section 3.1 Additional Amendment”) to this Agreement and the other Credit Documents; provided that such Section 3.1 Additional Amendments are within the requirements of Section 3.1(a) and do not become effective prior to the time that such Section 3.1 Additional Amendments have been consented to (including, without limitation, pursuant to (1) consents applicable to holders of Incremental Loans provided for in any Joinder Agreement and Refinancing Loans provided for in any Refinancing Amendment and (2) consents applicable to holders of any Extended Loans provided for in any Extension Amendment) by such of the Lenders, Credit Parties and other parties (if any) as may be required in order for such Section 3.1 Additional Amendments to become effective in accordance with Section 13.1.

(d) The effectiveness of any Extension Amendment shall be subject to the satisfaction on the date thereof of each of the conditions set forth in Section 3.1(a) and, to the extent reasonably requested by the Administrative Agent, receipt by the Administrative Agent of (i) items similar to those in Sections 6.3, 6.8, 6.11 and 6.13 with respect to the transactions contemplated by any Extension Amendment (with references to the Closing Date being replaced by the effective date of such Extension Amendment) (it being understood that any such items that are substantially consistent with those delivered on the Closing Date shall be satisfactory) and (ii) reaffirmation agreements and/or such amendments to the Security Documents as may be reasonably requested by the Collateral Agent in order to ensure that the Extended Loans are provided with the benefit of the applicable Credit Documents. Each exercise of the extension feature referred to in this Section 3.1 shall result in the Extended Loans and the Existing Class each being deemed a separate Class of Loans, and any Class of Loans may thereafter be extended in whole or in part pursuant to this Section 3.1 (whether or not such Class had previously been offered an extension pursuant to this Section 3.1).

3.2. Refinancing Amendments.

(a) At any time after the Closing Date, the Borrowers may obtain, from any Lender or any Additional Refinancing Lender, Credit Agreement Refinancing Indebtedness in respect of all or any portion of the Loans then outstanding under this Agreement (including any Incremental Loans, Extended Loans or other Refinancing Loans) pursuant to an amendment to this Agreement (such an amendment, a “Refinancing Amendment”). The effectiveness of any Refinancing Amendment shall be subject to (i) there being no Default or Event of Default on such date before or after giving effect to such Refinancing Loans; (ii) all representations and

-57-

warranties made by any Credit Party contained herein or in the other Credit Documents being true and correct in all material respects (except that any representation and warranty that is qualified as to “materiality” or “Material Adverse Effect” shall be true and correct in all respects) with the same effect as though such representations and warranties had been made on and as of the date of such date (except where such representations and warranties expressly relate to an earlier date, in which case such representations and warranties shall have been true and correct in all material respects (except that any representation and warranty that is qualified as to “materiality” or “Material Adverse Effect” shall be true and correct in all respects) as of such earlier date); and (iii) to the extent reasonably requested by the Administrative Agent, receipt by the Administrative Agent on the date thereof of (a) items similar to those in Sections 6 with respect to the transactions contemplated by any Refinancing Amendment (with references to the Closing Date being replaced by the effective date of such Refinancing Amendment) and (b) reaffirmation agreements and/or such amendments to the Security Documents as may be reasonably requested by the Collateral Agent in order to ensure that the Extended Loans are provided with the benefit of the applicable Credit Documents. The agent for the Credit Agreement Refinancing Indebtedness, if such Indebtedness is secured by a Lien on any asset of RailAmerica or any Restricted Subsidiary shall enter into each of the Intercreditor Agreements in the capacity as an agent for such Credit Agreement Refinancing Indebtedness.

(b) Each issuance of Credit Agreement Refinancing Indebtedness under Section 3.2(a) shall be in an aggregate principal amount that is (x) not less than $50,000,000 and (y) an integral multiple of $5,000,000 in excess thereof.

(c) The Administrative Agent shall promptly notify each Lender as to the effectiveness of each Refinancing Amendment. Each of the parties hereto hereby agrees that, upon the effectiveness of any Refinancing Amendment, this Agreement shall be deemed amended to the extent (but only to the extent) necessary to reflect the existence and terms of the Credit Agreement Refinancing Indebtedness incurred pursuant thereto. Any Refinancing Amendment may, without the consent of any other Lenders, effect such amendments to this Agreement and the other Credit Documents as may be necessary or appropriate, in the reasonable opinion of the Administrative Agent and the Borrowers, to effect the provisions of this Section 3.2. This Section 3.2 shall supersede any provisions in Section 13.1 to the contrary.

(d) The effectiveness of any Refinancing Amendment shall be subject to the satisfaction on the date thereof of each of the conditions set forth in Section 3.2(a) and, to the extent reasonably requested by the Administrative Agent, receipt by the Administrative Agent of (i) items similar to those in Sections 6 with respect to the transactions contemplated by any Refinancing Amendment (with references to the Closing Date being replaced by the effective date of such Refinancing Amendment) (it being understood that any such items that are substantially consistent with those delivered on the Closing Date shall be satisfactory) and (ii) reaffirmation agreements and/or such amendments to the Security Documents as may be reasonably requested by the Collateral Agent in order to ensure that the Refinancing Loans are provided with the benefit of the applicable Credit Documents. Each exercise of the refinancing feature referred to in this Section 3.2 shall result in the Refinancing Loans being deemed a separate Class of Loans.

-58-

SECTION 4. Fees

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

SECTION 5. Payments

5.1. Voluntary Prepayments.

(a) Subject to Section 5.1(b), the Borrowers shall have the right to prepay 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 10:00 a.m. (New York time) one Business Day prior to the date of such prepayment and shall promptly be transmitted by the Administrative Agent to each of the Lenders, (b) each partial prepayment of any Borrowing of Loans shall be in a multiple of $500,000 (or $1,000,000 in the case of Eurodollar Loans) and in an aggregate principal amount of at least $1,000,000 (or $5,000,000 in the case of Eurodollar Loans); 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. Each prepayment in respect of any Loans pursuant to this Section 5.1 (other than as otherwise set forth in Section 5.1(c)) shall be (a) applied to the Class or Classes of Loans as the Borrower may specify (but on a pro rata basis to the Lenders in such Class) and (b) applied to reduce Initial Loan Repayment Amounts, Incremental Loan Repayment Amounts, (subject to Section 3.1), Extended Loan Repayment Amounts and (subject to Section 3.2) Refinancing Loan Repayment Amounts, as the case may be, in each case, in such order as the Borrower may specify. Notwithstanding the foregoing, the Borrower may not repay (x) Extended Loans of any Extension Series unless such prepayment is accompanied by a pro rata repayment of Loans of the Existing Class from which such Extended Loans were converted (or such Loans of the Existing Class have otherwise been repaid in full) or (y) Refinancing Loans of any Refinancing Series unless such prepayment is accompanied by a pro rata repayment of the Class of Loans that such Refinancing Loans refinanced (if such Class of Loans was not refinanced in full).

(b) In the event that, within one year of the Closing Date, (x) the Borrowers make any prepayment of Initial Loans (including pursuant to Section 5.1(c) or 5.2(b)) in connection with any Repricing Transaction or (y) effect any amendment, supplement or modification hereof or hereto resulting in a Repricing Transaction, the Borrowers shall pay to the Administrative Agent, for the ratable account of the Lenders, without duplication, (I) in the case of clause (x), a prepayment premium of 1% of the amount of the Initial Loans being prepaid and (II) in the case of clause (y), a payment equal to 1% of the aggregate amount of the applicable Loans outstanding immediately prior to such amendment.

-59-

(c)

(i) Notwithstanding anything to the contrary in this Agreement, any Prepaying Borrower Party shall have the right at any time and from time to time to prepay Loans to the Lenders at a discount to the par value of such Loans (each, a “Discounted Voluntary Prepayment”) pursuant to the procedures described in this Section 5.1(c); provided that (A) no Discounted Voluntary Prepayment shall be made from the proceeds of any loan under the Revolving Credit Agreement, (B) any Discounted Voluntary Prepayment shall be offered to all Lenders on a pro rata basis based on the then outstanding Loans and (C) no Default or Event of Default has occurred and is continuing or would result from the Discounted Voluntary Prepayment (and RailAmerica shall provide the Administrative Agent a certificate to that effect).

(ii) To the extent a Prepaying Borrower Party seeks to make a Discounted Voluntary Prepayment, such Prepaying Borrower Party will provide written notice to the Administrative Agent substantially in the form of Exhibit N hereto (each, a “Discounted Prepayment Option Notice”) that such Prepaying Borrower Party desires to prepay the Loans in an aggregate principal amount specified therein by the Prepaying Borrower Party (each, a “Proposed Discounted Prepayment Amount”), in each case at a discount to the par value of such Loans as specified below. The Proposed Discounted Prepayment Amount of Loans shall not be less than $25,000,000. The Discounted Prepayment Option Notice shall further specify with respect to the proposed Discounted Voluntary Prepayment: (A) the Proposed Discounted Prepayment Amount of Loans, (B) a discount range (which may be a single percentage) selected by the Prepaying Borrower Party with respect to such proposed Discounted Voluntary Prepayment (representing the percentage of par of the principal amount of Loans to be prepaid) (the “Discount Range”), and (C) the date by which Lenders are required to indicate their election to participate in such proposed Discounted Voluntary Prepayment which shall be at least five Business Days following the date of the Discounted Prepayment Option Notice (the “Acceptance Date”).

(iii) Upon receipt of a Discounted Prepayment Option Notice in accordance with Section 5.1(c)(ii), the Administrative Agent shall promptly notify each Lender thereof. On or prior to the Acceptance Date, each such Lender may specify by written notice substantially in the form of Exhibit O hereto (each, a “Lender Participation Notice”) to the Administrative Agent (A) a minimum price (the “Acceptable Price”) within the Discount Range (for example, 80% of the par value of the Loans to be prepaid) and (B) a maximum principal amount (subject to rounding requirements specified by the Administrative Agent) of Loans with respect to which such Lender is willing to permit a Discounted Voluntary Prepayment at the Acceptable Price (“Offered Loans”). Based on the Acceptable Prices and principal amounts of Loans specified by the Lenders in the applicable Lender Participation Notice, the Administrative Agent, in consultation with the Prepaying Borrower Party, shall determine the applicable discount for Loans (the “Applicable Discount”), which Applicable Discount shall be (A) the percentage specified by the Prepaying Borrower Party if the Prepaying Borrower Party has selected a single percentage pursuant to Section 5.1(c)(ii) for the Discounted Voluntary Prepayment or (B) otherwise, the lowest Acceptable Price at which the Prepaying Borrower Party can pay the Proposed Discounted Prepayment Amount in full (determined by adding the principal amounts of Offered Loans commencing with the Offered Loans with the lowest Acceptable Price); provided, however, that in the event that such Proposed Discounted Prepayment Amount cannot be repaid in full at any Acceptable

-60-

Price, the Applicable Discount shall be the highest Acceptable Price specified by the Lenders that is within the Discount Range. The Applicable Discount shall be applicable for all Lenders who have offered to participate in the Voluntary Discounted Prepayment and have Qualifying Loans (as defined below). Any Lender with outstanding Loans whose Lender Participation Notice is not received by the Administrative Agent by the Acceptance Date shall be deemed to have declined to accept a Discounted Voluntary Prepayment of any of its Loans at any discount to their par value within the Applicable Discount.

(iv) The Prepaying Borrower Party shall make a Discounted Voluntary Prepayment by prepaying those Loans (or the respective portions thereof) offered by the Lenders (“Qualifying Lenders”) that specify an Acceptable Price that is equal to or lower than the Applicable Discount (“Qualifying Loans”) at the Applicable Discount; provided that if the aggregate proceeds required to prepay all Qualifying Loans (disregarding any interest payable at such time) would exceed the amount of aggregate proceeds required to prepay the Proposed Discounted Prepayment Amount, such amounts in each case calculated by applying the Applicable Discount, the Prepaying Borrower Party shall prepay such Qualifying Loans ratably among the Qualifying Lenders based on their respective principal amounts of such Qualifying Loans (subject to rounding requirements specified by the Administrative Agent). If the aggregate proceeds required to prepay all Qualifying Loans (disregarding any interest payable at such time) would be less than the amount of aggregate proceeds required to prepay the Proposed Discounted Prepayment Amount, such amounts in each case calculated by applying the Applicable Discount, the Prepaying Borrower Party shall prepay all Qualifying Loans.

(v) Each Discounted Voluntary Prepayment shall be made within four Business Days of the Acceptance Date (or such other date as the Administrative Agent shall reasonably agree, given the time required to calculate the Applicable Discount and determine the amount and holders of Qualifying Loans), upon irrevocable notice substantially in the form of Exhibit P hereto (each a “Discounted Voluntary Prepayment Notice”), delivered to the Administrative Agent no later than 11:00 a.m. (New York City time), three Business Days prior to the date of such Discounted Voluntary Prepayment, which notice shall specify the date and amount of the Discounted Voluntary Prepayment and the Applicable Discount determined by the Administrative Agent. Upon receipt of any Discounted Voluntary Prepayment Notice the Administrative Agent shall promptly notify each relevant Lender thereof. If any Discounted Voluntary Prepayment Notice is given, the amount specified in such notice shall be due and payable to the applicable Lenders, subject to the Applicable Discount on the applicable Loans, on the date specified therein together with accrued interest (on the par principal amount) to but not including such date on the amount prepaid.

(vi) To the extent not expressly provided for herein, each Discounted Voluntary Prepayment shall be consummated pursuant to reasonable procedures (including as to timing, rounding and calculation of Applicable Discount in accordance with Section 5.1(c)(iii) above) established by the Administrative Agent in consultation with the Borrower.

(vii) Prior to the delivery of a Discounted Voluntary Prepayment Notice, upon written notice to the Administrative Agent, the Prepaying Borrower Party may withdraw its offer to make a Discounted Voluntary Prepayment pursuant to any Discounted Prepayment Option Notice.

-61-

5.2. Mandatory Prepayments.

(a) Asset Sales. Not later than three (3) Business Days following the receipt of any Net Proceeds from any Asset Sale by RailAmerica or any of its Restricted Subsidiaries (other than an Asset Sale made pursuant to Section 10.4(a), (c), (d), (e), (f), (g), (h) or (i)) or from any Casualty Event, the Borrowers shall make prepayments of Loans in an aggregate amount equal to 100% of such Net Proceeds; provided, however, that (I) if at the time that any such prepayment would be required, any Credit Party is required to offer to repurchase or to prepay any Secured Notes or any Other Pari Passu Lien Obligations (or any Permitted Refinancing Indebtedness in respect thereof that is secured by the Collateral on a pari passu basis with the Obligations) pursuant to the terms of the documentation governing such Indebtedness with such Net Proceeds (such Secured Notes or any Other Pari Passu Lien Obligations (or any Permitted Refinancing Indebtedness in respect thereof) required to be offered to be so repurchased or prepaid, “Other Applicable Indebtedness”), then the Borrowers may apply such Net Proceeds on a pro rata basis (determined on the basis of the aggregate outstanding principal amount of the Loans and Other Applicable Indebtedness outstanding at such time (and in the case of such Other Applicable Indebtedness, at a prepayment price of no more than 100% of principal amount); provided that the portion of such Net Proceeds allocated to the Other Applicable Indebtedness shall not exceed the amount of such Net Proceeds required to be allocated to the Other Applicable Indebtedness pursuant to the terms thereof, and the remaining amount, if any, of such Net Proceeds shall be allocated to the Loans in accordance with the terms hereof) to the prepayment of the Loans and to the repurchase or prepayment of Other Applicable Indebtedness, and the amount of prepayment of the Loans that would have otherwise been required pursuant to this Section 5.2(a) shall be reduced by the amount of such Other Applicable Indebtedness so repaid with such Net Proceeds and to the extent the holders of Other Applicable Indebtedness decline to have such Other Applicable Indebtedness repurchased or prepaid, the declined amount shall promptly (and in any event within ten (10) Business Days after the date of such rejection) be applied to prepay the Loans in accordance with the terms hereof; and (II) so long as no Event of Default shall then exist or would arise therefrom, such Net Proceeds shall not be required to be so applied toward such prepayment to the extent that such Net Proceeds are used within 365 days of the date such Net Proceeds are received by RailAmerica or a Restricted Subsidiary to make an Investment in (w) any one or more businesses (provided that such Investment in any business is in the form of the acquisition of Equity Interests and results in RailAmerica or a Restricted Subsidiary, as the case may be, owning an amount of the Equity Interests of such business such that it constitutes a Restricted Subsidiary), (x) capital expenditures for RailAmerica and its Restricted Subsidiaries, (y) acquisitions of other assets that, in each of (w), (x), (y) and (z), are used or useful in a Similar Business that becomes a Restricted Subsidiary of RailAmerica or is held by RailAmerica or a Restricted Subsidiary or (z) in addition, in the case of a Casualty Event, the repair, restoration or replacement of the assets that were the subject of such Casualty Event; provided, further, that in the case of each of (w), (x), (y) and (z), to the extent the disposition giving rise to such Net Proceeds was Collateral, such Investment is concurrently added to the Collateral; provided, however, that RailAmerica and its Restricted Subsidiaries shall only be permitted to reinvest Net Proceeds of Asset Sales pursuant to the foregoing clause (II) to the extent (X) the

-62-

aggregate amount of Net Proceeds so reinvested from Asset Sales pursuant to such Clause (II) since the Closing Date does not exceed the greater of $200 million and 15% of Total Assets at the time of any such proposed reinvestment and (Y) such reinvestment is permitted by the terms of the Other Applicable Indebtedness and, if applicable, is considered a reinvestment in lieu of a prepayment thereof (it being understood that the limitations set forth in clauses (X) and (Y) shall not be applicable to the Net Proceeds from any Casualty Event). If required by the terms of any documentation governing Indebtedness incurred pursuant to Sections 10.1(h), (i), (k), (m) or (q) to place any such Net Proceeds in a collateral or control account with or on behalf of a representative of any such Indebtedness, the Net Proceeds from any such Asset Sale of Collateral shall be paid directly by the purchaser thereof to the Collateral Agent to be held in trust in an Asset Sale Proceeds Account for application in accordance with the terms of this Agreement; provided that (i) RailAmerica shall immediately after or prior to opening or designating any account as an Asset Sale Proceeds Account send a written notice identifying such account to the Administrative Agent and the Collateral Agent; (ii) the Asset Sale Proceeds Account shall not be subject to any Liens, other than the Lien of the Collateral Agent; (iii) neither RailAmerica nor any Restricted Subsidiary shall commingle the amounts in the Asset Sale Proceeds Account with any other amounts, other than any other proceeds of an Asset Sale or other sale of Collateral; and (iv) the proceeds of any Asset Sale permitted by Section 10.4 (other than Section 10.4(b)) shall not be required to be deposited in the Asset Sale Proceeds Account.

(b) Debt Issuance. Not later than one (1) Business Day following the receipt of any Net Proceeds of any Debt Issuance by RailAmerica or any of its Restricted Subsidiaries (or, in the case of a Debt Issuance comprised of Credit Agreement Refinancing Indebtedness, on the day of receipt of the Net Proceeds thereof), the Borrowers shall make prepayments of Loans in an aggregate amount equal to 100% of such Net Proceeds.

(c) Specified Equity Contribution. On the date that Rail America receives a Specified Equity Contribution, the Borrowers shall make prepayments of Loans in an aggregate amount equal to 100% of such Specified Equity Contribution.

(d) Excess Cash Flow. No later than ten (10) Business Days after each date on which the financial statements referred to in Section 9.1(a) for any fiscal year ending after December 31, 2012 are required to be delivered (without giving effect to any grace period), the Borrowers shall make prepayments of Loans in an aggregate amount equal to (A) the Applicable ECF Percentage of Excess Cash Flow for the Excess Cash Flow Period ended on the last day of the period covered by such financial statements minus (B) an amount equal to the principal amount of (x) any voluntary prepayments of Loans pursuant to Section 5.1(a) and (y) to the extent not already reducing Excess Cash Flow during such Excess Cash Flow Period, any prepayments of loans under the Revolving Credit Agreement to the extent accompanied by simultaneous and equivalent commitment reduction thereunder, in the case of each of clauses (x) and (y) during such Excess Cash Flow Period, other than in each case prepayments of Loans funded with the proceeds of Indebtedness.

(e) Application of Mandatory Prepayments. Subject to Section 5.2(g), each prepayment of Loans required by Section 5.2(a), (b), (c) or (d) or Section 10.9 shall be allocated pro rata among the Initial Loans, the Incremental Loans, the Extended Loans and the Refinancing

Loans (and allocated to the Lenders of such Loans on a pro rata basis) based on the applicable remaining Repayment Amounts due thereunder (provided that (i) any prepayment of Loans with the Net Cash Proceeds of Credit Agreement Refinancing Indebtedness shall be applied solely to each applicable Class of Refinanced Debt, and (ii) any Class of Incremental Loans may specify that one or more other Classes of Loans and Incremental Loans may be prepaid prior to such Class of Incremental Loans), and shall be applied within each Class of Loans to the scheduled installments of unpaid Repayment Amounts due in respect of such Loans first, to any payments due under Section 2.14 in the 12 months following such prepayment and, second, to the payments due under Section 2.14 on the applicable Repayment Dates following such 12-month period and the final repayment on the applicable Maturity Date, in each case on a pro rata basis; provided that (i) if permitted by the applicable Extension Amendment, if any Class of Extended Loans has been established hereunder, RailAmerica may, in its sole discretion, allocate any prepayment that would otherwise be paid to the Lenders of such Extended Loans to the Loans of the Existing Class, if any, from which such Extended Loans were converted and (ii) if permitted by the applicable Refinancing Amendment, if any Class of Refinancing Loans have been established hereunder, RailAmerica may allocate such prepayments in its sole discretion to the Loans of the Class of Loans, if any, that such Refinancing Loans partially refinanced. Subject to Section 5.2(g), with respect to each such prepayment, RailAmerica will, not later than the date on which such prepayments are required to be made, give the Administrative Agent written notice which shall include a calculation of the amount of such prepayment to be applied to each Class of Loans requesting that the Administrative Agent provide notice of such prepayment to each Initial Lender, Incremental Lender, Extending Lender or Refinancing Lender, as applicable.

(f) Exceptions for Foreign Subsidiaries. Notwithstanding anything to the contrary contained in this Section 5.2, (i) to the extent that any of or all the Net Proceeds of any Asset Sale or Casualty Event by a Foreign Subsidiary (“Foreign Disposition”) or Excess Cash Flow attributable to Foreign Subsidiaries are prohibited or delayed by applicable local law from being repatriated to the United States, the portion of such Net Proceeds or Excess Cash Flow so affected will not be required to be applied to repay Loans at the times provided in this Section 5.2 but may be retained by the applicable Foreign Subsidiary so long, but only so long, as the applicable local law will not permit repatriation to the United States (the Borrowers hereby agreeing to cause the applicable Foreign Subsidiary to promptly take all actions required by the applicable local law to permit such repatriation), and once such repatriation of any of such affected Net Proceeds or Excess Cash Flow is permitted under the applicable local law, such repatriation will be immediately effected and such repatriated Net Proceeds or Excess Cash Flow will be promptly (and in any event not later than two Business Days after such repatriation) applied (net of additional taxes payable or reserved against as a result thereof) to the repayment of the Loans pursuant to this Section 5.2 and (ii) to the extent that the Borrowers have determined in good faith that repatriation of any of or all the Net Proceeds of any Foreign Disposition or a Foreign Subsidiary’s Excess Cash Flow would have adverse tax cost consequences with respect to such Net Proceeds or Excess Cash Flow (including, without limitation, creating a tax obligation or requiring the use of net operating losses or similar tax credits to reduce such tax obligation), such Net Proceeds or Excess Cash Flow so affected may be retained by the applicable Foreign Subsidiary; provided that, in the case of this clause (ii), on or before the date on which any such Net Proceeds so retained would otherwise have been required to be applied to reinvestments or prepayments pursuant to Section 5.2(a) or any such Excess Cash Flow would have been required

-64-

to be applied to prepayments pursuant to Section 5.2(d), the Borrowers may apply an amount equal to such Net Proceeds or Excess Cash Flow to such reinvestments or prepayments, as applicable, as if such Net Proceeds or Excess Cash Flow had been received by the Borrowers rather than such Foreign Subsidiary, less the amount of additional taxes that would have been payable or reserved against (or, if applicable, the net operating losses that would have been applied) if such Net Proceeds or Excess Cash Flow had been repatriated (or, if less, the Net Proceeds or Excess Cash Flow that would be calculated if received by such Foreign Subsidiary).

(g) Rejection Right. RailAmerica shall notify the Administrative Agent in writing of any prepayment of Loans required to be made pursuant to Section 5.2(a), (b) (other than in the case of a prepayment arising from a Debt Issuance consisting of Credit Agreement Refinancing Indebtedness) or (d) at least three (3) Business Days prior to the date of such prepayment. Each such notice shall specify the date of such prepayment and provide a reasonably detailed calculation of the amount of such prepayment. The Administrative Agent will promptly notify each Lender holding Loans of the contents of RailAmerica’s prepayment notice and of such Lender’s pro rata share of the prepayment. Each Lender may reject all (but not less than all) of its pro rata share of any mandatory prepayment (such declined amounts, the “Declined Proceeds”) of Loans required to be made pursuant to Section 5.2(a), (b) (other than in the case of a prepayment arising from a Debt Issuance consisting of Credit Agreement Refinancing Indebtedness) or (d) by providing written notice (each, a “Rejection Notice”) to the Administrative Agent and RailAmerica no later than 5:00 p.m. (New York time) one Business Day after the date of such Lender’s receipt of notice from the Administrative Agent regarding such prepayment. If a Lender fails to deliver a Rejection Notice to the Administrative Agent within the time frame specified above or such Rejection Notice fails to specify the principal amount of the Loans to be rejected, any such failure will be deemed an acceptance of the total amount of such mandatory prepayment of Loans. Any Declined Proceeds remaining thereafter shall be retained by RailAmerica.

(h) [Reserved.]

(i) Payments. Amounts to be applied pursuant to Sections 5.1 and 5.2 to the prepayment of Loans shall be applied, as applicable, first to reduce outstanding ABR Loans. Any amounts remaining after each such application shall be applied to prepay Eurodollar Loans. Notwithstanding the foregoing, if the amount of any prepayment of Loans required under Sections 5.1 and 5.2 shall be in excess of the amount of the ABR Loans at the time outstanding (an “Excess Amount”), only the portion of the amount of such prepayment as is equal to the amount of such outstanding ABR Loans shall be immediately prepaid and, at the election of RailAmerica, such Excess Amount shall be either (A) deposited in an escrow account on terms satisfactory to the Collateral Agent and applied to the prepayment of Eurodollar Loans on the last day of the then next-expiring Interest Period for Eurodollar Loans; provided that (i) interest in respect of such Excess Amount shall continue to accrue thereon at the rate provided hereunder for the Loans which such Excess Amount is intended to repay until such Excess Amount shall have been used in full to repay such Loans and (ii) at any time while a Default has occurred and is continuing, the Collateral Agent may, and upon written direction from the Required Lenders shall, apply any or all proceeds then on deposit to the payment of such Loans in an amount equal to such Excess Amount or (B) prepaid immediately, together with any amounts owing to the Lenders under Section 2.11.

-65-

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 or the Administrative Agent, 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 Administrative Agent after an Event of Default specified in Section 11.5 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 and the Collateral Agent from the Credit Parties (other than in connection with 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 Hedge Agreements), third, to pay interest then due and payable on the Loans ratably, fourth, to prepay principal on the remaining Loans and Secured Hedge Agreements, ratably, and fifth, to the payment of any other Obligation due to the Administrative Agent or any Secured Party.

(d) Other than as expressly provided elsewhere herein, any Lender shall obtain payment in respect of any principal or interest on account of the Loans made by it any payment (whether voluntary, involuntary, through the exercise of any right of setoff, or otherwise) in excess of its ratable share (or other share contemplated hereunder) thereof, such Lender shall immediately (a) notify the Administrative Agent of such fact, and (b) purchase from the other Lenders such participations in the Loans made by them as shall be necessary to cause such purchasing Lender to share the excess payment in respect of any principal or interest on such Loans

-66-

or such participations, as the case may be, pro rata with each of them; provided that if all or any portion of such excess payment is thereafter recovered from the purchasing Lender under any of the circumstances described in Section 13.8 (including pursuant to any settlement entered into by the purchasing Lender in its discretion), such purchase shall to that extent be rescinded and each other Lender shall repay to the purchasing Lender the purchase price paid therefor, together with an amount equal to such paying Lender’s ratable share (according to the proportion of (i) the amount of such paying Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered, without further interest thereon. For avoidance of doubt, the provisions of this paragraph shall not be construed to apply to (A) any payment made by the Borrowers pursuant to and in accordance with the express terms of this Agreement as in effect from time to time or (B) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant permitted hereunder. The Borrowers agree that any Lender so purchasing a participation from another Lender may, to the fullest extent permitted by applicable Law, exercise all its rights of payment (including the right of setoff, but subject to Section 13.8) with respect to such participation as fully as if such Lender were the direct creditor of a Borrower in the amount of such participation. The Administrative Agent will keep records (which shall be conclusive and binding in the absence of manifest error) of participations purchased under this clause (d) and will in each case notify the Lenders following any such purchases or repayments. Each Lender that purchases a participation pursuant to this clause (d) shall from and after such purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement with respect to the portion of the Obligations purchased to the same extent as though the purchasing Lender were the original owner of the Obligations purchased.

(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 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 the amount due. In such event, if the Borrowers have not in fact made such payment, then each of the Lenders, severally (and not jointly) agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender 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;

-67-

(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 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 payable under this Section 5.4) 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)

-68-

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. 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 U.S. Tax 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.

-69-

(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) two 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 a payment made to a Lender under any Credit Document would be subject to U.S. federal withholding tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Administrative Agent and the Borrowers, at the time or times prescribed by law and at such time or times reasonably requested by the Administrative Agent or the Borrowers, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Administrative Agent or the Borrowers as may be necessary for the Administrative Agent and the Borrowers to comply with their respective obligations (including any applicable reporting requirements) under FATCA, to determine whether such Lender has complied with such Lender’s obligations under FATCA and to determine the amount to deduct and withhold from such payment, if any.

(g) 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(g) 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 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 (g) or any other provision of this Section 5.4.

-70-

(h) 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.

(b) Fees shall be calculated on the basis of a 360-day year for the actual days elapsed.

5.6. Limit on Rate of Interest.

(a) No Payment Shall Exceed Lawful Rate. Notwithstanding any other term of this Agreement, the Borrowers shall not be obliged to pay any interest or other amounts under or in connection with this Agreement in excess of the amount or rate permitted under or consistent with any applicable law, rule or regulation.

(b) Payment at Highest Lawful Rate. If the Borrowers are not obliged to make a payment which they would otherwise be required to make, as a result of Section 5.6(a), the Borrowers shall make such payment to the maximum extent permitted by or consistent with applicable laws, rules and regulations.

(c) Adjustment if Any Payment Exceeds Lawful Rate. If any provision of this Agreement or any of the other Credit Documents would obligate the Borrowers to make any payment of interest or other amount payable to any Lender in an amount or calculated at a rate which would be prohibited by any applicable law, rule or regulation, then notwithstanding such provision, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by law, such adjustment to be effected, to the extent necessary, as follows:

(i) firstly, by reducing the amount or rate of interest required to be paid by the Borrowers to the affected Lender under Section 2.8; and

(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

-71-

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.

[RESERVED]

SECTION 8.

Representations, Warranties and Agreements

In order to induce the Lenders to enter into this Agreement and to make the Loans as provided for herein, each Credit Party makes the following representations and warranties to, and agreements with, the Lenders, all of which shall survive the execution and delivery of this Agreement and the making of the Loans:

8.1. Corporate Status. Each Borrower and each Subsidiary (a) is a duly organized and validly existing corporation or other entity in good standing under the laws of the jurisdiction of its organization and has the corporate or other organizational power and authority to

-74-

own its property and assets and to transact the business in which it is engaged and (b) is duly qualified and is authorized to do business and is in good standing in all jurisdictions where it is required to be so qualified, except where the failure to be so qualified could not reasonably be expected to result in a Material Adverse Effect.

8.2. Corporate Power and Authority. Each Credit Party has the corporate or other organizational power and authority to execute, deliver and carry out the terms and provisions of the Credit Documents to which it is a party and has taken all necessary corporate or other organizational action to authorize the execution, delivery and performance of the Credit Documents to which it is a party.

SECTION 12. The Agents.

12.1. Appointment and Authority. Each Lender hereby irrevocably appoints (i) ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Senior Funding, Inc. to act on its behalf as the Administrative Agent, (ii) the Notes Collateral Agent to act as the Collateral Agent hereunder and under the other Credit Documents and (iii) the Administrative Agent, one of its Affiliates or another Person appointed by the Administrative Agent to act as the Collateral Agent (in the event that the Notes Collateral Agent is to be replaced as Collateral Agent in accordance with the terms of the Intercreditor Agreement) 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

-112-

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 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

-113-

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 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 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 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

-114-

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 Hedge Agreement unless and until it has received written notice thereof from the applicable Hedge 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.

12.6. Resignation of Agents. 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 (except that in the case of any Collateral held by the Collateral Agent on behalf of the Lenders or Letter of Credit Issuer under any of the Credit Documents, the retiring Collateral Agent shall continue to hold such Collateral as nominee until such time as a successor Collateral Agent is appointed) 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

-115-

such successor. After the retiring Agent’s resignation hereunder and under the other Credit Documents, the provisions of this Section 12 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 (or in the capacity set forth in the parenthetical in clause (i) above).

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) 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 and the form and substance of all evidence delivered in connection with establishing the satisfaction of each such condition; and

(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.

-116-

No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the Persons acting as the Lead Arrangers or the Joint Bookrunners 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 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, additions to tax 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. Security Agreement and Intercreditor Agreement. The Lenders (and the Secured Parties, by their acceptance of their status as Secured Parties) hereby (a) authorize and instruct the Administrative Agent and the Collateral Agent to enter into the Intercreditor Agreement (and make amendments and modifications to the Intercreditor Agreement contemplated by the Intercreditor Agreement) on their behalf and to act on their behalf thereunder, (b) agree to be bound by the terms of the Security Documents as if they were a party thereto and (c) agree not to contest the Collateral Agent’s actions taken or omitted to be taken pursuant to the Security Documents or contemplated thereby. It is hereby agreed that, for the purposes of Section 6.5 of the Security Agreement and Section 5.01 or 6.01 of the Mortgages, the security interests granted thereunder shall not terminate until all Obligations shall have been paid in full in cash. Furthermore, the Lenders authorize and instruct the Administrative Agent, one of its Affiliates or another Person appointed by the Administrative Agent, to become the “Collateral Agent” under the Intercreditor Agreement in accordance with the terms thereof on or after the time that no Secured Notes are outstanding (and to take all actions and to execute and deliver any and all documents the Administrative Agent determines are necessary or advisable to so execute and deliver in accordance therewith, and Borrowers agree to pay the expenses of the Administrative Agent in connection with the foregoing).

-117-

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 all the Loans shall have been paid in full, ratably in accordance with their respective portions of the Loans 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 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.

12.12. Collateral Release. In addition to any provisions of the Security Documents, each of the Secured Parties irrevocably authorize the Collateral Agent, at its option and in its discretion,

(a) to release any Lien on any property granted to or held by the Collateral Agent under any Credit Document (i) upon the Final Date, (ii) that is sold or to be sold as part of or in connection with any sale permitted hereunder or under any other Loan Document to a Person that is not a Credit Party or (iii) that constitutes “Excluded Property” (as such term is defined in the Security Agreement) or locomotives or railcars subject to a lease with any lessor that is not a Credit Party;

(b) to release any Subsidiary Guarantor from its obligations under this Agreement and other Security Documents if such Person ceases to be a Subsidiary as a result of a transaction permitted hereunder; and

(c) to subordinate or release any Lien on any property granted to or held by the Collateral Agent under any Credit Document to the holder of any Lien on such property that is granted pursuant to Section 10.2(c)(A), (f) or (g).

Upon request by the Collateral Agent at any time, the Borrowers will provide an officer’s certificate confirming the permissibility under the Credit Documents of any transaction in connection with which the any Credit Party is seeking a release of Collateral under this Section 12.12.

The Required Lenders may, or, with the written consent of the Required Lenders, the Administrative Agent may, from time to time, (a) enter into with the relevant Credit Party or Credit Parties written amendments, supplements or modifications hereto and to the other Credit Documents for the purpose of adding any provisions to this Agreement or the other Credit Documents or changing in any manner the rights of the Lenders or of the Credit Parties hereunder or thereunder or (b) waive, on such terms and conditions as the Required Lenders or the Administrative Agent, as the case may be, may specify in such instrument, any of the requirements of this Agreement or the other Credit Documents or any Default or Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification shall directly (i) forgive any portion of any Loan or extend the final scheduled maturity date of any Loan or reduce or extend the time for payment of any amortization payment hereunder or reduce the stated rate, or forgive any portion, or extend the date for the payment, of any interest, Fee or prepayment premium payable hereunder (other than as a result of waiving the applicability of Section 2.8(c)), or amend or modify any provisions of Section 13.8(a), in each case without the written consent of each Lender directly and adversely affected thereby, or (ii) amend, modify or waive any provision of this Section 13.1 or reduce the percentages specified in the definitions of the terms “Required Lenders” or “Applicable Percentage” or consent to the assignment or transfer by the Borrowers of their rights and obligations under any Credit Document to which it is a party (except as permitted pursuant to Section 10.3), in each case without the written consent of each Lender, (iii) amend, modify or waive any provision of Section 12 as the same applies to any Agent, or any other provision hereof as the same applies to the rights or obligations of any Agent, in each case without the written consent of such Agent, (iv) amend, modify or waive any provision of Section 5.3(a), Section 5.3(c) or Section 10.3(g) without the written consent of each Lender directly and adversely affected thereby, (v) release all or substantially all of the Guarantors under the Guarantee (except as expressly permitted by the Guarantee) or, except as permitted in Section 13.1(b), release all or substantially all of the Collateral granted under the Security Agreement without the prior written consent of each Lender, (vi) amend Section 2.9 so as to permit Interest Period intervals greater than six months without regard to the consent of each Lender, without the written consent of each Lender, or (vii) decrease the amount or allocation of any optional or mandatory prepayment to be received by any Lender holding any Loans without the written consent of such Lender. Any such waiver and any such amendment, supplement or modification shall apply equally to each of the affected Lenders and shall be binding upon the Borrowers, such Lenders, the Administrative Agent and all future holders of the affected Loans. In the case of any waiver, the Borrowers, the Lenders, the Administrative Agent and the Collateral Agent shall be restored to their former positions and rights hereunder and under the other Credit Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing, it being understood that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Notwithstanding the foregoing (x) if the Administrative Agent and the Borrowers shall have jointly identified a technical error or mistake in any Credit Document (including without

-119-

limitation an incorrect cross reference), the Administrative Agent (and/or the Collateral Agent) and the Borrowers (and any other relevant Credit Party) may fix such error or mistake by amending such Credit Document without the consent of any Lender and (y) RailAmerica will not enter into any amendment contemplated by the second sentence of Section 11 of the Intercreditor Agreement without the prior written consent of the Administrative Agent (but it being understood that only the consent of the Administrative Agent (and no Lender or Secured Party in its capacity as such) shall be required to effectuate any such amendment pursuant to such second sentence).

(b) Any Liens granted to the Collateral Agent by the Credit Parties on any Collateral for the benefit of the Secured Parties shall automatically be released (i) upon the Final Date and (ii) if such Collateral constitutes property being sold or disposed of (other than to a Credit Party) (or property of a Subsidiary Guarantor whose capital stock is being sold in a transaction that will result in such Subsidiary Guarantor being released from the Guarantee in accordance with the terms thereof) to the extent such sale or disposition is in compliance with the terms of this Agreement. 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 Collateral 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 Commitments and the outstanding Loans 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.

-121-

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. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

13.4. Survival of Representations and Warranties. All representations and warranties made hereunder, in the other Credit Documents and in any document, certificate or statement delivered pursuant hereto or in connection herewith shall survive the execution and delivery of this Agreement and the making of the Loans hereunder.

13.5. Payment of Expenses and Taxes. The Borrowers, jointly and severally, agree (a) to pay or reimburse the Agents for all their reasonable out-of-pocket costs and expenses (other than Taxes) incurred in connection with the development, syndication and execution of, and any amendment, waiver, supplement or modification to, this Agreement and the other Credit Documents and any other documents prepared in connection herewith or therewith, and the consummation and administration of this Agreement and the transactions contemplated hereby and thereby, including the reasonable fees, disbursements and other charges of counsel to the Agents, (b) to pay or reimburse each Lender, the Collateral Agent and the Administrative Agent for all its reasonable and documented costs and expenses incurred in connection with the enforcement or preservation of any rights (including workout proceedings) under this Agreement, the other Credit Documents and any such other documents, including the reasonable fees, disbursements and other charges of counsel to each Lender and of counsel to the Collateral Agent and the Administrative Agent and (c) to pay, indemnify, and hold harmless each Lender, the Collateral Agent and the Administrative Agent and their respective directors, officers, employees, trustees, agents and affiliates from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever, excluding any Taxes (other than Taxes representing losses or damages with respect to any non-Tax claims), whether brought by any Credit Party, any stockholder or creditor of any Credit Party, or any other Person, including reasonable and documented fees, disbursements and other charges of counsel, with respect to the execution, delivery, enforcement, performance (and, with respect to each Agent and its directors, officers, employees, trustees and agents, syndication, administration of this Agreement) and any actual or proposed use of proceeds of any Loan, the other Credit Documents and any such other documents, including any of the foregoing relating to the violation of, noncompliance with or liability under, any Environmental Law or any actual or alleged presence of Hazardous Materials related to the Borrowers or any of their Subsidiaries, including any of the foregoing arising out of or based on any Environmental Claim related to the Borrowers or any actual or alleged presence, Release, or threat of Release of Hazardous Materials the Borrowers or any of their Subsidiaries, (all the foregoing in this clause (c), collectively, the “indemnified liabilities”); provided that the Borrowers shall have no obligation hereunder to the Administrative Agent, the Collateral Agent or any Lender nor any of their respective directors, officers, employees and agents with respect to indemnified liabilities arising from the gross negligence or willful misconduct of the party to be indemnified (as determined in a final non-appealable judgment by a court of competent jurisdiction). The agreements in this Section 13.5 shall survive repayment of the Loans and all other amounts payable hereunder.

-122-

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, 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, 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 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 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 or delayed) of:

(A) except with respect to any assignment made in connection with the primary syndication of the Initial Loans, RailAmerica; provided that no consent of RailAmerica shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee; provided further that if RailAmerica has not consented to any such assignment or objected thereto by written notice to the Administrative Agent within 5 Business Days after having received notice thereof, if the Administrative Agent has been informed thereof, the Administrative Agent shall provide a second notice to RailAmerica (the “Second Consent Notice”); provided, further, that RailAmerica shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within 3 Business Days after having received the Second Consent Notice; and

(B) the Administrative Agent (provided that no consent of the Administrative Agent shall be required for an assignment to a Lender, an Affiliate of a Lender or an Approved Fund);

provided, further, however, notwithstanding the foregoing or anything to the contrary set forth herein (x) any assignment (and any proposed assignment) of any Loans to an Affiliated Lender shall also be subject to the requirements and limitations set forth in Sections 13.6(f), (g) and (h), (y) RailAmerica and its Subsidiaries may not be assignees of any Loans (but may make Discounted Voluntary Prepayments in accordance with Section 5.1(c)) and (z) no natural person may be an assignee or Participant with respect to any Loans.

-123-

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

(A) except in the case of an assignment by a Lender to an Affiliate of such Lender or an Approved Fund with respect to such 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 $1,000,000 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; provided that only one such fee shall be payable in the event of simultaneous assignments to or from two or more Approved Funds; 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 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, 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 and each Affiliated Lender Assignment and Assumption 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 owing to each

-124-

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 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 and, with respect to its own interest only, 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 or the Administrative Agent, sell participations to one or more banks or other entities other than in each case RailAmerica or any Affiliate thereof (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 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 and 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, except to the extent such entitlement to a greater payment results from a change in any Requirement of Law after the Participant became a Participant.

-125-

(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 (and if required by an applicable Requirement of Tax Law or in connection with a Tax audit of 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 J, as the case may be, evidencing the Loans 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.

(f) Any Lender may, at any time, assign all or a portion of its rights and obligations with respect to Loans under this Agreement to a Person who is or will become, after such assignment, an Affiliated Lender, in each case subject to the following limitations:

(i) the assigning Lender and the Affiliated Lender purchasing such Lender’s Loans shall execute and deliver to the Administrative Agent an assignment agreement substantially in the form of Exhibit Q-1 hereto (an “Affiliated Lender Assignment and Assumption”);

-126-

(ii) Affiliated Lenders will not receive information provided solely to Lenders by the Administrative Agent or any Lender and will not be permitted to attend or participate in conference calls or meetings attended solely by the Lenders and the Administrative Agent, other than the right to receive notices of prepayments and other administrative notices in respect of its Loans required to be delivered to Lenders pursuant to Section 2;

(iii) at the time of such assignment (and after giving effect thereto), the aggregate principal amount of Loans held by Affiliated Lenders shall not exceed 20% of the aggregate principal amount of all Loans then outstanding;

(iv) as a condition to each assignment pursuant to this clause (f), the Administrative Agent shall have been provided a notice in the form of Exhibit Q-2 to this Agreement in connection with each assignment to an Affiliated Lender or a Person that upon effectiveness of such assignment would constitute an Affiliated Lender pursuant to which such Affiliated Lender shall waive any right to bring any action in connection with such Loans against the Administrative Agent, in its capacity as such; and

(v) each Affiliated Lender agrees to notify the Administrative Agent promptly (and in any event within 10 Business Days) if it acquires any Person who is also a Lender. Such notice shall contain the type of information required and be delivered to the same addressee as set forth in Exhibit Q-2.

(g) Notwithstanding anything in Section 13.1 or the definition of “Required Lenders,” to the contrary, for purposes of determining whether the Required Lenders have (i) consented (or not consented) to any amendment, modification, waiver, consent or other action with respect to any of the terms of any Credit Document or any departure by any Credit Party therefrom, or subject to Section 13.6(i), any plan of reorganization pursuant to the Bankruptcy Code, (ii) otherwise acted on any matter related to any Credit Document, or (iii) directed or required the Administrative Agent or any Lender to undertake any action (or refrain from taking any action) with respect to or under any Credit Document, no Affiliated Lender shall have any right to consent (or not consent), otherwise act or direct or require the Administrative Agent or any Lender to take (or refrain from taking) any such action and:

(i) all Loans held by any Affiliated Lenders shall be deemed to be not outstanding for all purposes of calculating whether the Required Lenders and Required Class Lenders (in respect of a Class of Loans) have taken any actions; and

(ii) all Loans held by Affiliated Lenders shall be deemed to be not outstanding for all purposes of calculating whether all Lenders have taken any action unless the action in question affects such Affiliated Lender in a disproportionately adverse manner than its effect on other Lenders.

(h) Notwithstanding anything in this Agreement or the other Credit Documents to the contrary, each Affiliated Lender hereby agrees that and each Affiliated Lender Assignment and Assumption shall provide a confirmation that, if a proceeding under any Debtor Relief Law shall be commenced by or against the Borrowers or any other Credit Party at a time when such Lender is an Affiliated Lender, such Affiliated Lender irrevocably authorizes and empowers the Administrative

-127-

Agent to vote on behalf of such Affiliated Lender with respect to the Loans held by such Affiliated Lender in any manner in the Administrative Agent’s sole discretion, unless the Administrative Agent instructs such Affiliated Lender to vote, in which case such Affiliated Lender shall vote with respect to the Loans held by it as the Administrative Agent directs; provided that such Affiliated Lender shall be entitled to vote in accordance with its sole discretion (and not in accordance with the direction of the Administrative Agent) in connection with any plan of reorganization to the extent any such plan of reorganization proposes to treat any Obligations held by such Affiliated Lender in a disproportionately adverse manner to such Affiliated Lender than the proposed treatment of similar Obligations held by Lenders that are not Affiliated Lenders. Furthermore, each Lender agrees to notify the Administrative Agent promptly (and such notice shall contain the type of information required and be delivered to the same addressee as set forth in Exhibit Q-2).

13.7. Replacements of Lenders under Certain Circumstances. The Borrowers shall be permitted to replace any Lender that (a) requests reimbursement for amounts owing pursuant to Section 2.10, 2.12 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 or (c) 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, 4.1, 5.1 (assuming such Section had not been amended pursuant to such amendment to remove or delete the premium set forth therein), 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

-128-

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 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.

-129-

13.13. Submission to Jurisdiction; Waivers. Each Credit Party hereby irrevocably and unconditionally:

(a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Credit Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the exclusive general jurisdiction of the courts of the State of New York located in the State, County and City of New York, the courts of the United States of America for the Southern District of New York and appellate courts from any thereof;
