         taxes and all other withholdings required by law on the full amount
         payable pursuant to this SECTION 3(A); PROVIDED, HOWEVER, that nothing

                           ii. Within two (2) business days following the

group health plan pursuant to the Consolidated Omnibus Budget Reconciliation Act
of 1985 ("COBRA") and under any replacement plan the Company may obtain at the
conclusion of the Executive's and his qualified dependents' COBRA entitlement,
which shall be on a level consistent with the coverage afforded to the Executive
and his qualified dependents prior to the Termination Date to the extent
reasonably possible, until the first to occur of (i) the end of the month
containing the fifth (5th) anniversary of the Effective Date, and (ii) the date
that the Executive becomes eligible for substantially equivalent coverage under
another employer's group health plan. In furtherance of this obligation, the
Executive agrees to take all necessary steps to elect and maintain continued
COBRA coverage for the greatest period permitted by law and to assist the
Company in obtaining coverage under any replacement plan.

         the Performance Period running from January 1, 2001, through December
         31, 2003 (provided, however, that the parties agree that no such
         payment is payable inasmuch as the Performance Targets were not
         achieved),

                           ii. his entire Performance Award for the Performance
         Periods running from January 1, 2002, through December 31, 2004, and
         from January 1, 2003 through December 31, 2005, and

                          FOR SETTLEMENT PURPOSES ONLY
                         UNLESS EXECUTED BY BOTH PARTIES

                           iii. a pro-rated portion equal to seventy-five
         percent (75%) of his Performance Award for the Performance Period
         running from January 1, 2004, through December 31, 2006 (based on a
         Termination Date of April 7, 2004).

                  The payments for each such Performance Period shall be
calculated pursuant to the formula provided in Section 5.6 of the LTIP and shall
be paid to the Executive in the time and manner specified in Section 5.10 of the
LTIP.

                  (d) STOCK OPTIONS AND RESTRICTED STOCK. A total of 116,666
unvested options to purchase shares of the Company's Common Stock previously
granted to the Executive by the Company shall become vested in the Executive as
of the Effective Date. These options, together with 1,433,334 previously vested
options (collectively, the "OPTIONS"), shall remain exercisable until the second
(2nd) anniversary of the Effective Date, with the exception of the Options
granted as of January 1, 1998, which shall remain exercisable until January 1,
2008. Any Options not exercised in accordance with the foregoing shall expire.
In addition, 24,918 unvested shares of restricted shares previously granted to
the Executive (the "RESTRICTED SHARES") shall become vested in the Executive as
of the Effective Date, and the Company shall cause any restrictive legend on any
such restricted shares to be removed within thirty (30) days thereof. (Copies of
the Option Agreements for each of the foregoing Option grants and copies of the
Restricted Shares are attached hereto as EXHIBIT 4 and EXHIBIT 5, respectively.)

                  (e) INDEMNIFICATION. The Company and Executive hereby agree to
perform all of their respective obligations under the Indemnification Agreement
(the "INDEMNIFICATION AGREEMENT") between Rail America, Inc., and Gary O. Marino
dated June 23, 2000 (a copy of which is attached hereto as EXHIBIT 6) which
agreement remains in full force and effect, except as provided in SECTION 10
hereof.

                  (f) CONTINGENT ADDITIONAL PAYMENTS. The parties represent and
warrant that this Agreement is made without any expectation that an event will
occur that would result in application of Sections 280G or 4999 of the Internal
Revenue Code of 1986, as amended (the "CODE"). Nonetheless, in the event the
Internal Revenue Service or any state or local taxing authority determines that
any payment, distribution or other action by the Company to or for the benefit
of the Executive pursuant to this Agreement or otherwise would be subject to the
excise tax imposed by Code Section 4999 (or its successor or other provision
that imposes a similar excise tax) or any excise tax that may be imposed by a
state and/or local law, or any interest or penalties being imposed on the
Executive with respect to any such excise taxes (such excise taxes, together
with any such interest and penalties, are hereinafter collectively referred to
as the "EXCISE TAX"), then the provisions of Section 7 of that certain agreement
between the Executive and the Company dated June 20, 2000, as amended effective
September 1, 2002 (the "2000/02 AGREEMENT") shall apply by treating as a
"Payment" for purposes of Section 7 of the 2000/02 Agreement, any payment,
distribution or other action by the Company to or for the benefit of the
Executive pursuant to the terms of this Agreement or otherwise (including any
additional payments required under this SECTION 3(F)). Except as required to
give effect to this SECTION 3(F), the 2000/02 Agreement shall be null and void,
and the Executive shall be entitled to no payments or benefits thereunder.

                          FOR SETTLEMENT PURPOSES ONLY
                         UNLESS EXECUTED BY BOTH PARTIES

                  (g) EXECUTIVE'S DEATH. If the Executive dies before receiving
all payments to which he is entitled under this Agreement, or any of the
agreements or programs referred to above, any payment that would have been made
to the Executive will be made to the Executive's surviving spouse, if any, or,
if none or circumstances are such that it is not possible to determine whether
the Executive or his surviving spouse survived, then to the Executive's estate.
If Executive's surviving spouse dies before receiving all payments to which she
is entitled under this SECTION 3(G), any payment that would have been made to
her will be made to her estate.

         4. NO FURTHER COMPENSATION. The Executive acknowledges and agrees that
no further compensation or benefits or other monies are owed to the Executive by
the Company, other than the Severance Benefits described in SECTION 3 above, and
any other rights of the Executive under the Company's Employees 401K Savings
Plan (in which the Executive is fully vested with respect to the employer's
contribution) and the Retirement Executive Plan Basic Plan Document, a/k/a/ the
RailAmerica, Inc. Executive Deferred Compensation Plan (the "2003 EXECUTIVE
PLAN") (in which the Executive is fully vested with respect to the employer's
contribution) and conversion rights under the life and disability insurance
features of the Company's Health and Welfare Plan. For this purpose, Company
shall provide or cause to be provided to the Executive the customary notices
concerning benefits as are provided to terminated employees.

         5. JOINT PRESS RELEASE. The parties hereto agree that, upon the
execution of this Agreement, the Company shall issue the press release attached
hereto as EXHIBIT 7.

         6. NON-COMPETITION AND NON-SOLICITATION. In consideration for the
Company's provision of the Severance Benefits under SECTION 3 of this Agreement,
the Executive agrees to the following:

                  (a) GENERAL. The Executive acknowledges that he has performed
services for and on behalf of the Company and has acquired Confidential
Information and has had access to Materials (as each of those terms is defined
below) that will directly affect the Consolidated Group. Accordingly, the
parties deem it necessary to provide protective non-competition and
non-solicitation provisions in this Agreement. "CONSOLIDATED GROUP" as used
above and elsewhere in this Agreement shall mean the Company and its
subsidiaries and affiliates.

                  (b) NON-COMPETITION AND NON-SOLICITATION. The Executive agrees
with the Company that for a period of twelve (12) months from the Effective
Date, the Executive shall not, directly or indirectly, without the prior written
consent of the Board, engage in the following:

                           i. perform any services or duties in any capacity,
         whether as a consultant, independent contractor, agent, director,
         officer, manager, supervisor or employee, or otherwise, for any person
         or entity engaged in any business in the United States that was engaged
         in by any member of the Consolidated Group at any time during the
         period in which the Executive was employed by the Company; PROVIDED,
         HOWEVER, that, for purposes of this SECTION 6(B)(I), (A) in no event
         shall a purely passive personal or family investment of less than five

                          FOR SETTLEMENT PURPOSES ONLY
                         UNLESS EXECUTED BY BOTH PARTIES

         percent (5%) of the equity of any entity, without more, be construed as
         the performance of duties or services for such entity; (B) a business
         which is first engaged in by the Consolidated Group after the Effective
         Date of this Agreement shall be considered to be a business that was
         engaged in during the Executive's employment by the Consolidated Group
         only if and to the extent that the Executive agrees in writing at the
         time of the Consolidated Group's commencement or acquisition of such
         business that it will be so considered; and (C) the Executive may
         become involved with a short-line freight railroad, if such railroad
         does not operate track anywhere in the United States or Canada or in
         Australia (the later restriction so long as the Company owns Freight
         Australia).

                           ii. The Executive shall not, directly or indirectly,
         for himself or for any other person, firm, corporation, partnership,
         association or other entity, employ or attempt to employ, or enter into
         any contractual arrangement with, any employee or former employee of
         any member of the Consolidated Group (whether or not such employment is
         full-time or part-time or pursuant to a written contract), other than
         the Executive's personal secretary, unless such employee or former
         employee has not been employed by any member of the Consolidated Group
         for a period in excess of six (6) months.

                  (c) The covenants of the Executive set forth in this SECTION 6
are separate and independent covenants, for which valuable consideration has
been paid, the receipt, adequacy and sufficiency of which are hereby
acknowledged by the Executive, and which have been made by the Executive to
induce the Company to enter into this Agreement. Each of the aforesaid covenants
may be availed of, or relied upon, by the Company in any court of competent
jurisdiction for the basis of injunctive relief, as permitted under SECTION 8
hereof. The covenants set forth in this SECTION 6 are cumulative to each other
and to all other covenants of the Executive in favor of the Company contained in
this Agreement. Should any covenant, term or condition in this SECTION 6 become
or be declared invalid or unenforceable, the parties request that such
unenforceable provision be modified consistent with the intent of this SECTION 6
so that it shall be enforceable as modified.

         7. CONFIDENTIALITY.

                  (a) SEPARATION AGREEMENT. The parties hereto covenant and
agree that this Agreement and its terms and conditions are, collectively and
independently, totally confidential and from the date of this Agreement forward,
shall forever be kept totally confidential and shall not in any manner or for
any reason by disclosed by either party without the express written consent of
the other party, except on a "need to know basis" (i) to the immediate family
members of the Executive, all of whom shall be informed of and be bound by the
provisions of this paragraph; (ii) to the attorneys and accountants of either
party; (iii) as may be required by government agencies, such as the Internal
Revenue Service; or (iv) pursuant to court order or subpoena compelling such

                                  Page 5 of 12

                         UNLESS EXECUTED BY BOTH PARTIES

disclosure. Should either party or their representatives receive any such
subpoena or court order compelling disclosure, that party shall immediately
notify the other party so that it may have the opportunity to interpose an
objection.

                  (b) BUSINESS INFORMATION. In the course of the Executive's
relationship with the Consolidated Group, some or all of the members of the
Consolidated Group have disclosed or made known to the Executive, and the
Executive has been given access to or has become acquainted with, certain
information, business plans, strategies, trade secrets and the like, relating to
or useful in one or more of the businesses of the Consolidated Group
(collectively "CONFIDENTIAL INFORMATION"), and which the Company considers
proprietary and desires to maintain confidential. As a material inducement to
the Company to enter into this Agreement, the Executive covenants and agrees
that, at all times after the Termination Date, the Executive shall not in any
manner, either directly or indirectly, divulge, disclose or communicate to any
person or entity, except to or for the benefit of the Consolidated Group or as
directed by the Chief Executive Officer of the Company, any of the Confidential
Information which he may have acquired in the course of or as an incident to his
relationship with any member of the Consolidated Group, including, without
limitation, pursuant to his employment, the parties agreeing that such
Confidential Information affects the successful and effective conduct of the
businesses of the Consolidated Group and its goodwill, and that any breach of
the terms of this SECTION 7 is a material breach of this Agreement. All
equipment, documents, memoranda, reports, records, computer software, disks,
tapes, other means of electronic data storage, files, materials, samples, books,
correspondence, lists, other written and graphic records and the like
(collectively, the "MATERIALS"), affecting or relating to one or more of the
businesses of the Consolidated Group, which the Executive may have prepared,
used, constructed, observed, possessed or controlled shall be and remain the
sole property of the Consolidated Group. On or before the Termination Date, the
Executive shall deliver to the Company all of the Materials, Confidential
Information and all copies thereof in the custody or control of the Executive
and shall certify in writing that he has retained no copy of any Materials.

         8. INJUNCTIVE RELIEF. The covenants of the Executive set forth in this
Agreement are separate and independent covenants, for which valuable
consideration has been paid, the receipt, adequacy and sufficiency of which are
hereby acknowledged by the Executive, and which have been made by the Executive
to induce the Company to enter into this Agreement. Each of the aforesaid
covenants may be availed of, or relied upon, by the Company or any other member
of the Consolidated Group in any court of competent jurisdiction for the basis
of injunctive relief. Should any covenant, term or condition in this Agreement
become or be held to be overly broad as to geography, time, activity or subject
so as to be unenforceable at law or equity, such provision or provisions shall
be construed by the appropriate judicial body by limiting and reducing it or
them so as to be enforceable to the maximum extent compatible with applicable
law. It is the intent of the parties that the provisions of this Agreement be
enforced to the greatest extent allowable in law or equity.

                         UNLESS EXECUTED BY BOTH PARTIES

         9. NO CHARGES FILED. The Executive and the Company mutually represent
and warrant that neither has filed any claims or causes of action against the
other or, with respect to Executive's representation and warranty, against any
other member of the Consolidated Group, including but not limited to any charges
of discrimination against the Company, with any federal, state or local agency
or court.

         10. NO ADMINISTRATIVE PROCEEDING TO BE FILED. The Executive and the
Company each agree not to institute any administrative proceeding or lawsuit
against the other or, with respect to the Executive's agreement, any other
member of the Consolidated Group, in violation of SECTION 13 below, and
represent and warrant that, to their best knowledge, no other person or entity
has initiated or is authorized to initiate such administrative proceedings or
lawsuit on his or its behalf. Furthermore, each party agrees not to encourage
any other person or suggest to any other person that he or she institute any
legal action or claim against each other or, with respect to the Executive's
agreement, the Consolidated Group or any past and present shareholders,
directors, officers, or agents. To the extent that any provision of Section 10
of the Indemnification Agreement may suggest a right of the Company contrary to
the Company's agreement in this SECTION 10, Section 10 of the Indemnification
Agreement is of no further force and effect.

         11. NON-DISPARAGEMENT. The Executive agrees not to make any disparaging
or negative comment to any other person or entity regarding (a) any member of
the Consolidated Group, (b) any of the owners, directors, officers,
shareholders, members or employees of any member of the Consolidated Group, (c)
the working conditions at the Company, or (d) the circumstances surrounding the
Executive's separation from the Company. The Company's officers and directors
and the officers and directors of any other member of the Consolidated Group
agree not to make any disparaging or negative comment to any other person or
entity regarding the Executive.

         12. DUTY OF COOPERATION. The parties hereto agree to cooperate with
each other and each other's attorneys in connection with any threatened or
pending litigation against the Company or any member of the Consolidated Group,
or against the Executive. The Executive agrees to make himself available upon
reasonable notice to prepare for and appear at deposition or at trial in
connection with any such matters, and the Company agrees to make the appropriate
persons available upon reasonable notice to prepare for and appear at deposition
or at trial in connection with any such matters. Notwithstanding anything
contained herein to the contrary, the Executive shall not be obligated to appear
as an expert consultant or expert witness in connection with any matter.
Furthermore, the parties hereto agree to cooperate fully in effecting an orderly
transition with regard to the termination of the Executive's employment and the
transition of his duties to other employees of the Company. The foregoing
obligations shall be without additional cost to the party to whom cooperation is
provided.

         13. MUTUAL GENERAL RELEASES.

                  (a) THE EXECUTIVE'S RELEASE. The Executive, on behalf of
himself and his spouse, heirs, executors, administrators, personal
representatives and assigns, hereby unconditionally and irrevocably releases,
covenants not to sue and provides a complete waiver of all rights and claims
that may have arisen, whether known or unknown, until the Effective Date, to the
Company and each member of the Consolidated Group, all of each of their past and
present parents, subsidiaries, affiliated and related entities and divisions and
departments, and each of their owners, directors, officers, shareholders,
members, employees, attorneys and agents, and their predecessors, successors and
assigns. This includes, but is not limited to, rights or claims based on Title
VII of the Civil Rights Act of 1964, the Civil Rights Act of 1866, the Civil
Rights Act of 1991, the Age Discrimination in Employment Act of 1967 (including
the Older Workers Benefit Protection Act), the Americans with Disabilities Act,
the Fair Labor Standards Act, the Equal Pay Act, the Family and Medical Leave
Act, the Employee Retirement Income Security Act of 1974, the Florida Civil
Rights Act of 1992, and the Railway Labor Act of 1926, as any of the foregoing
may be amended from time to time, and any common law, public policy, contract
(whether oral or written, express or implied) or tort law, including claims for
defamation, and any other local, state or federal law, regulation or ordinance
having any bearing whatsoever on the terms and conditions of the Executive's
employment with or the termination of his employment by the Company. In addition
to waiving his right to file any charge or complaint on his own behalf, the
Executive hereby waives his right to participate in any charge or complaint
which may be made by any other person or organization on his behalf before any
federal, state or local court or administrative agency against any of the
foregoing releasees, except as such waiver is prohibited by law. Should any such
charge be filed, the Executive agrees that he will not accept any relief or
recovery therefrom.

                  (b) THE COMPANY'S RELEASE. The Company and the other members
of the Consolidated Group hereby unconditionally and irrevocably release and
forever discharge the Executive, and covenant not to sue and not to assert
against the Executive, any causes of action, claims or demands whatsoever, both
known and unknown, at law or in equity, or before any agency or commission of
local, state and federal governments, arising under any law or other statutory,
administrative and common law that the Company or any other member of the
Consolidated Group ever had, now has or hereafter can, shall or may have for or
by reason of any cause whatsoever, up to the Termination Date, including, but
not limited to any and all claims and causes of action arising out of the
Executive's employment with the Company, whether based on any federal, state or
local statute or ordinance or founded in tort, contract (oral, written or
implied) or any other common law or equitable basis.

                  (c) Notwithstanding anything contained in this SECTION 13 to
the contrary, however, this Agreement is not intended and shall not operate or
be deemed to constitute a release, waiver, discharge or impairment of any right
or right to prosecute any claim or action on any right that may arise after the
Effective Date, including, with respect to the Executive, his rights under the
2003 Executive Plan and the Company's Employees 401K Savings Plan.

         14. CERTAIN VIOLATIONS. In the event of the Executive's material

            RAILAMERICA, INC. NONQUALIFIED DEFERRED COMPENSATION TRUST

      This RailAmerica, Inc. Nonqualified Deferred Compensation Trust Agreement
is made this 3rd day of January, 1997 by and between RailAmerica, Inc. (the
"Company") and Donald D. Redfearn (the "Trustee");

      WHEREAS, the Company has adopted the nonqualified deferred compensation
Plans as listed in Appendix One hereto and may adopt additional nonqualified
deferred compensation Plans for the benefit of eligible employees (the "Plan");

      WHEREAS, the Company has incurred or expects to incur liability under the
terms of such Plans with respect to the individuals participating in such Plans;

      WHEREAS, the Company wishes to establish a trust (hereinafter called
"Trust") and to contribute to the Trust assets that shall be held therein,
subject to the claims of the Company's creditors in the event of the Company's
Insolvency, a herein defined, until paid to Plan participants and their
beneficiaries in such manner and at such times as specified in the Plans;

      WHEREAS, it is the intention of the parties that this Trust shall
constitute an unfunded arrangement and shall not affect the status of the Plans
as an unfunded plan maintained for the purpose of providing deferred
compensation for a select group of management of highly compensated employees
for purposes of Title I of the Employee Retirement Income Security Act of 1974;

      WHEREAS, it is the intention of the Company to make contributions to the
Trust to provide itself with a source of funds to assist it in the meeting of
its liabilities under the Plans;

      NOW, THEREFORE, the parties do hereby establish the Trust and agree that
the Trust shall be comprised, held and disposed of as follows:

      1.    ESTABLISHMENT OF TRUST.

            (a)   The Company hereby deposits with the Trustee in trust the
amount shown on Appendix Two hereto, which shall become the principal of the
Trust to be held, administered and disposed of by the Trustee as provided in
this Trust Agreement:

            (b)   The Trust hereby established is irrevocable.

            (c)   The Trust is intended to be a grantor trust, of which the
Company is the grantor, within the meaning of subpart E, part I, subchapter I,
chapter 1, subtitle A of the Internal Revenue Code of 1986, as amended, and
shall be construed accordingly.

            (d)   The principal of the Trust, and any earnings thereon shall be
held separate and apart from other funds of the Company and shall be used
exclusively for the uses and purposes of Plan participants and general creditors
as herein set forth. Plan participants and their beneficiaries shall have no
preferred claim on, or any beneficial ownership interest in, any assets of the
Trust. Any rights created under the Plans and this Trust Agreement shall be mere
unsecured contractual rights of Plan participants and their beneficiaries
against the Company. Any assets held by the Trust will be subject to the claims
of the Company's general creditors under federal and state law in the event of
Insolvency, as defined in Section 3(a) herein.

<PAGE>

            (e)   The Company, in its sole discretion, may at any time, or from
time to time, make additional deposits of cash or other property in trust with
the Trustee to augment the principal to be held, administered and disposed of by
the Trustee as provided in this Trust Agreement. Neither the Trustee nor any
Plan participant or beneficiary shall have any right to compel such additional
deposits.

      2.    PAYMENTS TO PLAN PARTICIPANTS AND THEIR BENEFICIARIES.

            (a)   The Company shall deliver to the Trustee a schedule (the
"Payment Schedule") that indicates the amounts payable in respect of each Plan
participant (and his or her beneficiaries), that provides a formula or other
instructions acceptable to the Trustee for determining the amounts so payable,
the form in which such amount is to be paid (as provided for or available under
the Plans), and the time of commencement for payment of such amounts. Except as
otherwise provided herein, the Trustee shall make payments to the Plan
participants and their beneficiaries in accordance with such Payment Schedule.
The Trustee shall make provision for the reporting and withholding of any
federal, state or local taxes that may be required to be withheld with respect
to the payment of benefits pursuant to the terms of the Plans and shall pay
amounts withheld to the appropriate taxing authorities or determine that such
amounts have been reported, withheld and paid by the Company.

            (b)   The entitlement of a Plan participant or his or her
beneficiaries to benefits under the Plans shall be determined by the Company or
such party as it shall designate under the Plans, and any claim for such
benefits stall be considered and reviewed under the procedures set out in the
Plans.

            (c)   The Company may make payment of benefits directly to Plan
participants or their beneficiaries as they become due under the terms of the
Plans. The Company shall notify the Trustee of its decision to make payment of
benefits directly prior to the time amounts are payable to participants or their
beneficiaries. In addition, if the principal of the Trust, and any earnings
thereon, are not sufficient to make payments of benefits in accordance with the
terms of the Plans, the Company shall make the balance of each such payment as
it falls due. The Trustee shall notify the Company where principal and earnings
are not sufficient.

      3.    TRUSTEE RESPONSIBILITY REGARDING PAYMENTS TO TRUST BENEFICIARY WHEN
            COMPANY IS INSOLVENT.

            (a)   The Trustee shall cease payment of benefits to Plan
participants and their beneficiaries if the Company is Insolvent. The Company
shall be considered "Insolvent" for purposes of this Trust Agreement if (i) the
Company is unable to pay its debts as they become due, or (ii) the Company is
subject to a pending proceeding as a debtor under the United States Bankruptcy
Code.

            (b)   At all times during the continuance of this Trust, as provided
in Section 1(d) hereof, the principal and income of the Trust shall be subject
to claims of general creditors of the Company under federal and state law as set
forth below.

                  (1)   The Board of Directors and the Chief Executive Officer
of the Company shall have the duty to inform the Trustee in writing of the
Company's Insolvency. If a person claiming to be a creditor of the Company
alleges in writing to the Trustee that the Company has become Insolvent, the
Trustee shall determine whether the Company is Insolvent

                                       -2-

<PAGE>

and, pending such determination, the Trustee shall discontinue payment of
benefits to Plan participants or their beneficiaries.

                  (2)   Unless the Trustee has actual knowledge of the Company's
Insolvency, or has received notice from the Company or a person claiming to be a
creditor alleging that the Company is Insolvent, the Trustee shall have no duty
to inquire whether the Company is Insolvent. The Trustee may in all events rely
on such evidence concerning the Company's solvency as may be furnished to the
Trustee and that provides the Trustee with a reasonable basis for making a
determination concerning the Company's solvency.

                  (3)   If at any time the Trustee has determined that the
Company is Insolvent, the Trustee shall discontinue payments to Plan
participants or their beneficiaries and shall hold the assets of the Trust for
the benefit of the Company's general creditors. Nothing in this Trust Agreement
shall in any way diminish any rights of Plan participants or their beneficiaries
to pursue their rights as general creditors of the Company with respect to
benefits due under the Plans or otherwise.

                  (4)   The Trustee shall resume the payment of benefits to Plan
participants or their beneficiaries in accordance with Section 2 of this Trust
Agreement only after the Trustee has determined that the Company is not
Insolvent (or is no longer Insolvent).

            (c)   Provided that there are sufficient assets, if the Trustee
discontinues the payment of benefits from the Trust pursuant to Section 3(b)
hereof and subsequently resumes such payments, the first payment following such
discontinuance shall include the aggregate amount of all payments due to Plan
participants or their beneficiaries under the terms of the Plans for the period
of such discontinuance, less the aggregate amount of any payments made to Plan
participants or their beneficiaries by the Company in lieu of the payments
provided for hereunder during any such period of discontinuance.

      4.    PAYMENTS TO COMPANY.

            Except as provided in Section 3 hereof, after the Trust has become
irrevocable, the Company shall have no right or power to direct the Trustee to
return to the Company or to divert to others any of the Trust assets before all
payment of benefits have been made to Plan participants and their beneficiaries
pursuant to the terms of the Plans.

      5.    INVESTMENT AUTHORITY.

            (a)   The Trust Fund shall be held in trust by the Trustee and shall
be invested and reinvested as provided in this Section 5, without distinction
between principal and Income and without regard to the restrictions of the laws
of the State of Florida, or any other jurisdiction, relating to the investment
of Trust Funds. The Trustee shall invest and reinvest the Trust Fund in its
discretion, except as otherwise directed by the Company, or in accordance with
Section 5(d) in accordance with the directions of an Investment Manager. The
Trustee shall be under no duty or obligation to review any investment to be
acquired, held or disposed of pursuant to such directions nor to make any
recommendation with respect to the disposition or continued retention of any
such investment.

            (b)   In addition to the more general investment powers provided
below, the Trustee may invest in securities (including stock or rights to
acquire stock) or obligations issued

                                       -3-

<PAGE>

by the Company. All rights associated with assets of the Trust shall be
exercised by the Trustee or the person designated by the Trustee, and shall in
no event be exercisable by or rest with Plan participants. The Company shall
have the right at anytime, and from time to time in its sole discretion, to
substitute assets of equal fair market value for any asset held by the Trust.
This right is exercisable by the Company in a nonfiduciary capacity without the
approval or consent of any person in a fiduciary capacity.

            (c)   The Company shall establish specific investment policies and
guidelines for Trust Funds. The Trustee shall be responsible only for investing
the Trust Fund in accordance with such policies and guidelines. If any change in
such policies or guidelines is subsequently deemed appropriate, notice of such
change shall be promptly communicated by the Company to the Trustee, but the
Trustee shall be under no duty to take or refrain from taking any action based
on such changes prior to receiving such notice.

            (d)   The Company may appoint one or more than one Investment
Manager to direct the investment of the Trust Fund. Upon the effective date of
such appointment, such Investment Manager shall have the sole power, without
prior consultation with the Trustee, to manage and direct the acquisition and
disposition of the Trust Fund. The Investment Manager shall keep such records
and make such reports to the Trustee as may be specified in the agreement
appointing such Investment Manager. The Company at its discretion also may
terminate the appointment of any Investment Manager. The Company shall notify
the Trustee of such termination and, in the absence of specific directions from
the Company or the appointment of a successor Investment Manager for the
Investment Account, the Company shall be responsible for the management and
control of the assets formerly managed by the Investment Manager.

            (e)   To the extent neither the Company nor an Investment Manager
furnishes directions as to the investment of the Trust Fund, the Trustee may
retain uninvested cash or cash balances, without being required to pay interest
thereon, or may invest such assets in short-term investments and one of the
commingled funds described in Section 5(f)(8).

            (f)   The Trustee shall have the power to do all things and execute
such instruments as it may deem necessary or proper to carry out its
responsibilities under this Trust Agreement, including the following powers:

                  (1)   To invest any and all monies in stock of the Company,
other stocks, bonds, securities, insurance policies insuring the lives of
employees covered by any Plan, mutual funds, investment company or trust shares,
mortgages, notes, choses in action, real estate, improvements thereon, and other
property acceptable to the Trustee;

                  (2)   To sell, exchange, or otherwise dispose of any property
at any time held or acquired by the Trust Fund, at public or private sale, for
cash or on terms, without advertisement, including the right to lease for any
term;

                  (3)   To vote in person or by proxy any corporate stock or
other security and to agree to or take, or refrain from taking, any other action
necessary or appropriate for a shareholder or owner in regard to any
reorganization, merger, consolidation, liquidation, bankruptcy or other
procedure or proceeding affecting any stock, bond, note or other property;

                                       -4-

<PAGE>

                  (4)   To compromise, settle, adjust or otherwise act in any
reasonable manner whatsoever on any claim or demand by or against the Trust Fund
and to agree to any rescission or modification of any contact or agreement
affecting the Trust fund;

                  (5)   To deposit any stock, bond or other security in any
depository or other similar institution and to register any stock, bond or other
security in the name of any nominee, without the addition of words indicating
that such security is held in a fiduciary capacity, but accurate records shall
be maintained showing that such security is a Trust Fund asset and the Trustee
shall be responsible for the acts of such depository or nominee;

                  (6)   To hold cash (including, without limitation, in
non-interest bearing accounts) in such amounts and for such time as may be in
its opinion reasonable for the proper management of the Trust Fund;

                  (7)   To grant, sell, purchase, or exercise any option of any
kind or description whatsoever to purchase or sell any security or other
property which is a permissible investment under this Section 5, provided the
Trustee in no event shall grant or sell any option under which any person can
require the Trust Fund to sell any security or other property which the Trust
Fund at the time of such grant or sale does not hold in an amount sufficient to
cover such option and any other outstanding option granted or sold by the
Trustee, and the Trustee in no event shall dispose of any security or other
property covering any option until such option is exercised or otherwise
expires;

                  (8)   To invest all, or any part, of the assets of the Trust
Fund in any common, collective or group trust fund which is maintained under
section 584 of the Code or Revenue Ruling 81-100, 1981-1 C.B. 326, by the
Trustee or any bank which is a member of an "affiliated group" (as that term is
defined in section 1504 of the Code) with the Trustee, the provisions of which
common, collective or group trust fund upon such investment shall automatically
be adopted and made a part of this Trust Agreement for the period such
investment is made in such common, collective or group trust fund;

                  (9)   To make such other investments without regard to any law
now or hereafter in force limiting the investments of trustees or other
fiduciaries.

            (g)   With respect to any policy of life insurance that the Trustee
owns or under which the death benefits are made payable to the Trustee, the
Trustee shall have the following specific powers and responsibilities;

                  (1)   If the Trustee is the owner of any such policy, the
Trustee reserves all available benefits, privileges, payments, dividends,
surrender values, options, conversion rights and elections, including the right
at any time or times to change the beneficiary, to borrow or otherwise receive
the surrender value, to pledge or assign the policy or its proceeds as
collateral security for any loan which the owner or owners may obtain from any
lender, including a Trustee under this agreement individually or a parent or
affiliate company, and to withdraw the policy if deposited with the trustees,
without any duty on the trustees to see its return.

                  (2)   Upon the death of the insured under the policy the
Trustee shall take such action as they deem best to collect the policy proceeds,
paying the expenses of collection from the Trust Fund, but the Trustee need not
enter into or maintain any litigation to

                                       -5-

<PAGE>

enforce payment on the policy until indemnified to their satisfaction against
all expenses and liabilities to which it might by any such litigation be
subjected. The Trustee may release the insurance company from its liability
under the policy and make any compromise which the trustees deem proper.

                  (3)   The insurance company shall not take notice of the
provisions of this Agreement or see to the application of the policy proceeds,
and the Trustee's receipt to the insurance company shall be a complete release
for any payment made and shall bind every participant or beneficiary under this
Agreement.

      6.    DISPOSITION OF INCOME.

            During the term of this Trust, ail income received by the Trust, net
of expenses and taxes, shall be accumulated and reinvested.

      7.    ACCOUNTING BY TRUSTEE.

            The Trustee shall keep accurate and detailed records of all
investments, receipts, disbursements, and all other transactions required to be
made, including such specific records, as shall be agreed upon in writing
between the Company and the Trustee. Within 90 days following the close of each
calendar year and within 30 days after the removal or resignation of the
Trustee, the Trustee shall deliver to the Company a written account of its
administration of the Trust during such year or during the period from the close
of the last preceding year to the date of such removal or resignation, setting
forth all investments, receipts, disbursements and other transactions effected
by it, including a description of all securities and investment purchased and
sold with the cost or net proceeds of such purchases or sales (accrued interest
paid or receivable being shown separately), and showing all cash, securities and

         WHEREAS, the Trust was established effective January 3, 1997, pursuant
to agreement between RailAmerica, Inc. (the "COMPANY") and Donald D. Redfearn
(the "TRUSTEE") to hold assets contributed to fund benefits under certain
nonqualified deferred compensation plans or agreements;

         WHEREAS, the current primary beneficiary of the Trust is Gary O. Marino
(the "EXECUTIVE"), who as served as Chairman, President and Chief Executive
Officer of the Company; and

the written consent of the Trustee and all beneficiaries;

         NOW, THEREFORE, the Trust is hereby amended as follows, effective as
provided above:

         1. Section 2 of the Trust is amended to add the following subsection
(d):

                  (d) If, due to changed federal law or regulations, the Trustee
         or a Plan participant determines that any amount contributed to the
         Trust on behalf of the participant should be includable in the
         participant's gross income for federal income tax purposes before
         distribution of such amounts under the Plan otherwise would be
         permitted, such amounts, as adjusted for investment performance, shall
         be paid immediately to the participant, notwithstanding any other
         provision of the Plan or of the participant's election concerning
         payment. The amount of any such payment shall reduce the participant's
         account under the Plan.

         2. Section 15 of the Trust is added to read as follows:

                  15.      CONTROL BY COMMITTEE

         obligation to pay benefits due under the Plans nor the obligation to
         pay Trust expenses, which obligations shall remain with the Company.
         Nothing in this SECTION 15(A) shall change in any way the rights of the
         Company and its creditors under SECTION 3 hereof.

                  (b) The Committee provided for in the preceding paragraph may
         consist of from one (1) to five (5) persons. Marino shall notify the
         Company and the Trustee(s) then serving of the appointment of the

            NOW, THEREFORE, for good and valuable consideration, the receipt,
adequacy and sufficiency of which are hereby acknowledged, the parties hereto do

stockholders of the Incentive Plan as provided in the Employment Agreement. The

any extent after such term expires.

            3.    Grant as Non-Qualified Stock Options; Other Options. The

assignments or transfers (a) will not be treated as arms-length transactions
that would result in the assignment or transfer being a taxable event for the
purpose of Section 83 of the Code and the regulations thereunder, and (b) are
then permitted by Securities and Exchange Commission ("SEC") Rule 16b-3 and
Form S-8.

            5.    Partial Exercise. Exercise of the Options may be made in part
at any time and from time to time within the limits set forth in Section 2
above, except that the Options may not be exercised for a fraction of a share.

Company shall use its best efforts to file a registration statement on SEC Form
S-8 under the Securities Act of 1933, as amended (the "1933 Act"), relating to
the exercise of the Options and to keep such registration statement effective
and current at all times during which any of the Options is exercisable. If for
any reason the registration statement is not effective and current when the
Optionee elects to exercise any Options, the Optionee agrees (i) that his
purchase of shares of Common Stock upon such exercise will not be made with a
view toward their distribution as defined in the 1933 Act; (ii) that such shares
of Common Stock may not be transferred or hypothecated unless, in the opinion of
counsel to the Company, such transfer or hypothecation would be in compliance
with the registration provisions of the 1933 Act and relevant state securities
laws, or pursuant to exemptions therefrom; and (iii) to sign a certificate to
such effect at the time of exercising the Options and that the certificate for
the shares so purchased may be inscribed with a legend to ensure compliance with
the 1933 Act and relevant state securities laws.

            7.    Method of Exercising Options. Subject to the terms and
conditions of this Agreement, the Options may be exercised by written notice to
the Company, at the principal executive office of the Company. Such notice shall
state the election to exercise the Options and the number of shares in respect
of which they are being exercised and shall be signed by the Optionee. Such
notice shall be accompanied by the payment of the full purchase price for such
shares, which

                                      - 2 -
<PAGE>

shall be payable (i) in cash; (ii) by certified check or bank cashier's check
payable to the order of the Company in the amount of such purchase price; (iii)
by delivery to the Company of shares of Common Stock having a fair market value
(as defined in Section 9.B) equal to such purchase price, provided that such
shares have been owned by the Optionee for at least six (6) months or such other
period as the Company may determine is necessary to avoid adverse accounting
treatment by the Company; (iv) in the event that the exercise of the Options is
covered by an effective registration statement, by the delivery from a broker to
the Company of an amount of loan proceeds necessary to pay such purchase price,
pursuant to the Optionee's instructions to the broker to sell some or all of the
shares of Common Stock to be issued upon exercise of the Options and to repay
the loan from the proceeds of the sale, to deliver the remaining cash proceeds,
less commissions, brokerage fees and interest charges to the Optionee and to
deliver any remaining shares to the Optionee; or (v) by any combination of the
methods of payment described in (i) through (iv) above. The Company shall
deliver a certificate or certificates representing the shares purchased as soon
as practicable after the notice and payment shall be received. The certificate
or certificates for the shares purchased shall except as otherwise instructed in
the case of an exercise pursuant to (iv) above, all be registered in the name of
the Optionee and shall be delivered to the Optionee. All shares purchased upon
the exercise of Options shall be fully paid and non-assessable. The Optionee
shall not have the rights of a stockholder with respect to the shares covered by
the Options until the date of issuance of a stock certificate to him for such
shares. Except as expressly provided in Section 9, no adjustment shall be made
for dividends or similar rights for which the record date is before the date
such stock certificate is issued.

            8.    No Obligation To Exercise Options. The grant and acceptance of
the Options imposes no obligation on the Optionee to exercise the Options.

            9.    Adjustments. The Optionee's rights with respect to unexercised
Options shall be adjusted as provided in the Incentive Plan. In addition, upon
the occurrence of any of the following events, the Optionee's rights with
respect to unexercised Options shall be adjusted as hereinafter provided:

                  A.    Stock Dividends and Stock Splits. If the shares of
Common Stock shall be subdivided or combined into a greater or smaller number of
shares, or if the Company shall issue any shares of Common Stock as a stock
dividend on its outstanding Common Stock, the number of shares of Common Stock
deliverable upon the exercise of Options shall be appropriately increased or
decreased proportionately, and appropriate adjustments shall be made in the
purchase price per share to reflect such subdivision, combination or stock
dividend.

                  B.    Acquisition of the Company. If the Company is to be
consolidated with or acquired by another entity, in a merger, sale of all or
substantially all of the Company's assets or otherwise, in a transaction in
which the Company is not the surviving parent entity (an 'Acquisition"), the
Board (or the board of directors of the entity assuming the obligations of the
Company hereunder (the "Successor Board")) shall, with respect to outstanding
Options, take one or more of the following actions: (i) make appropriate
provision for the continuation of such Options by substituting on an equitable
basis for the shares of Common Stock then subject to such

                                      - 3 -
<PAGE>

Options the consideration payable with respect to the outstanding shares of
Common Stock in connection with the Acquisition; (ii) accelerate the date of
exercise of such Options or of any installment of such Options; (iii) upon
written notice to the Optionee, provide that all Options must be exercised, to
the extent then exercisable, within a specified number of days after the date of
such notice, at the end of which period the Options shall terminate; or (iv)
terminate all Options in exchange for a cash payment equal to the excess of the
fair market value of the shares subject to such Options (to the extent then
exercisable) over the exercise price thereof. For purposes of this Agreement,
"fair market value" shall be determined as of the last business day for which
the prices or quotes discussed in this sentence are available prior to the date
of determination and shall mean (a) the average (on that date) of the high and
low sales prices of the Common Stock on the principal national securities
exchange on which the Common Stock is traded, if the Common Stock is then traded
on a national securities exchange, or in the Nasdaq National Market, if the
Common Stock is then quoted in such market; or (b) the average of the high and
low bid prices (on that date) by an established quotation service (including for
these purposes the Nasdaq Small-Cap Market) for over-the-counter securities, if
the Common Stock is not traded or quoted on a national securities exchange or in
the Nasdaq National Market. However, if the Common Stock is not publicly traded
on the date of determination, "fair market value" shall be deemed to be the fair
value of the Common Stock as determined by the Board (or the Successor Board)
after taking into consideration all factors which it deems appropriate,
including, without limitation, recent sale and bid prices of the Common Stock in
private transactions negotiated at arm's length.

                  C.    Recapitalization or Reorganization. In the event of a
recapitalization or reorganization of the Company (other than in a transaction
described in subparagraph A or B above) pursuant to which securities of the
Company or of another entity are issued with respect to the outstanding shares
of Common Stock, the Optionee upon exercising the Options shall be entitled to
receive for the purchase price paid upon such exercise the securities that he
would have received if he had exercised the Options prior to such
recapitalization or reorganization.

                  D.    Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Options shall terminate
immediately prior to the consummation of such proposed action, or at such other
time and subject to such other conditions as shall be determined by the Board.

                  E.    Issuances of Securities. Except as expressly provided
herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or
exercise price of shares subject to the Options.

                  F.    Fractional Shares. No fractional shares shall be issued
upon exercise of the Options, and the Optionee shall receive from the Company
cash in lieu of such fractional shares.

                                       FOR
                                 GARY O. MARINO

and not a nonqualified stock option. The Optionee hereby acknowledges receipt of
a copy of the Plan and agrees to be bound by all of the terms and conditions
hereof and thereof and all applicable laws and regulations.

of this Agreement, or in the Plan, the Option is exercisable in installments as
provided below, which shall be cumulative. To the Extent that the Option has

time or from time to time prior to the expiration of the Option as provided
herein. The following table indicates each date (the "Vesting Date") upon which
the Optionee shall be entitled to exercise the Option with respect to the number

proportionate or partial vesting in the periods prior to each Vesting Date, and

      15.   Tax Consequences. Set forth below is a brief summary as of the date
of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE.
AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT
A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

            (a)   Exercise of Option. There will be no regular federal income
tax liability upon the exercise of the Option, although the excess, if any, of
the fair market value of the Shares on the date of exercise over the exercise
price will be treated as an adjustment to the alternative minimum tax for
federal tax purposes and may subject the Optionee to the alternative minimum tax
in the year of exercise.

            (b)   Disposition of Shares. If Shares transferred pursuant to the
Option are held for at least one year after exercise and are disposed of at
least two years after the date of grant, any gain realized on disposition of the
Shares will also be treated as long-term capital gain for federal income tax
purposes. If Shares purchased under an Option are disposed of within such
one-year period or within two years after the Date of Grant, any gain realized
on such disposition will be treated as compensation income (taxable at ordinary
income rates) to the extent of the difference between the exercise price and the
lesser of (1) the fair market value of the Shares on the date of exercise or (2)
the sale price of the Shares.

            (c)   Notice of Disqualifying Disposition of Option Shares. If
Optionee sells or otherwise disposes of any of the Shares acquired pursuant to
the Option on or before the later of

                                       4

<PAGE>

(1) the: date two years after the date of grant. (2) the date one year after the
date of exercise, the Optionee shall immediately notify the Company in writing
of such disposition. Optionee agrees that Optionee may be subject to the income
tax withholding by the Company on the compensation income recognized by the
Optionee from the early disposition by payment in cash or out of the current
earnings paid to the Optionee.

      IN WITNESS WHEREOF, the undersigned have executed this Agreement as of
the 20th day of July, 2001.

<PAGE>

which the Option is being exercised, and such other representations and
agreements as to the holder's investment intent with respect to such Shares as
may be required by the Company pursuant to the provisions of the Plan. Such
written notice shall be signed by the Optionee and shall be delivered in person
or by certified mail to the Secretary of the Company. The written notice shall
be accompanied by payment of the exercise price. This Option shall be deemed to
be exercised after both (a) receipt by the Company of such written notice
accompanied by the exercise price and (b) arrangements that are satisfactory to
the Committee in its sole discretion have been made for Optionee's payment to
the Company of the amount, if any, that is necessary to be withheld in
accordance with applicable Federal or state withholding requirements. No Shares
will be issued pursuant to the Option unless and until such issuance and such
exercise shall comply with all relevant provisions of applicable law, including
the requirements of any stock exchange upon which the Shares then may be traded.

      5.    Method of Payment. Payment of the exercise price shall be by any of
the following, or a combination thereof, at the election of the Optionee: (a)
cash; (b) check; or (c) with Shares that have been held by the Optionee for at
least 6 months (or such other Shares as the Company determines will not cause
the Company to recognize for financial accounting purposes a charge for
compensation expense), or (d) such other consideration or in such other manner
as may be determined by the Board or the Committee in its absolute discretion.

      6.    Termination of Option.

            (a)   Any unexercised portion of the Option shall automatically and
without notice terminate and become null and void at the time of the earliest to
occur of:

                  (i)   three months after the date on which the Optionee's
employment is terminated other than by reason of (A) Cause, which, solely for
purposes of this Plan, shall mean the termination of the Optionee's employment
by reason of the Optionee's willful misconduct or gross negligence, (B) a mental
or physical disability (within the meaning of Internal Revenue Code Section
22(e)) of the Optionee as determined by a medical doctor satisfactory to the
Committee, or (C) death of the Optionee;

                  (ii)  immediately upon the termination of the Optionee's
employment for Cause;

                  (iii) twelve months after the date on which the Optionee's
employment is terminated by reason of mental or physical disability (within the
meaning of Section 22(e) of the Code) as determined by a medical doctor
satisfactory to the Committee;

                  (iv)  (A) twelve months after the date of termination of the
Optionee's employment by reason of the death of the Optionee, or, if later, (B)
three months after the date on which the Optionee shall die if such death shall
occur during the one year period specified in Subsection 6(a)(iii) hereof: or

                  (v)   the tenth anniversary of the date as of which the Option
is granted.

                                        2

<PAGE>

            (b)   To the extent not previously exercised, (i) the Option shall
terminate immediately in the event of (1) the liquidation or dissolution of the
Company, or (2) any reorganization, merger, consolidation or other form of
corporate transaction in which the Company does not survive, unless the
successor corporation, or a parent or subsidiary of such successor corporation,
assumes the Option or substitutes an equivalent option or right pursuant to
Section 10(c) of the Plan, and (ii) the Committee or the Board in its sole
discretion may by written notice ("cancellation notice") cancel, effective upon
the consummation of any corporate transaction described in Subsection 9(b)(i) of
the Plan in which the Company does survive, the Option (or portion thereof) that
remains unexercised on such date. The Committee or the Board shall give written
notice of any proposed transaction referred to in this Section 6(b) a reasonable
period of time prior to the closing date for such transaction (which notice may
be given either before or after approval of such transaction), in order that
Optionee may have a reasonable period of time prior to the closing date of such
transaction within which to exercise the Option if and to the extent that it
then is exercisable (including any portion of the Option that may become
exercisable upon the closing date of such transaction). The Optionee may
condition his exercise of the Option upon the consummation of a transaction
referred to in this Section 6(b).

      7.    Transferability. The Option is not transferable otherwise than by
will or the laws of descent and distribution, and during the lifetime of the
Optionee the Option shall be exercisable only by the Optionee. The terms of
this Option shall be binding upon the executors, administrators, heirs,
successors and assigns of the Optionee.

      8.    No Rights of Stockholders. Neither the Optionee nor any personal
representative (or beneficiary) shall be, or shall have any of the rights and
privileges of, a stockholder of the Company with respect to any shares of Stock
purchasable or issuable upon the exercise of the Option, in whole or in part,
prior to the date of exercise of the Option.

      9.    Acceleration of Exercisability of Option. This Option shall become
immediately fully exercisable in the event of a "Change in Control", as defined
in the Plan or in Exhibit "A", if any, attached hereto, or in the event that the
Committee or the Board exercises its discretion to provide a cancellation notice
with respect to the Option pursuant to Section 6(b) hereof. The Company may in
its sole discretion accelerate the date on which this Option may be exercised
and may accelerate the vesting of any Shares subject to this Option or
previously acquired by the exercise of any Option.

      10.   No Right to Continued Employment. Neither the Option nor this
Agreement shall confer upon the Optionee any right to continued employment or
service with the Company.

      11.   Law Governing. This Agreement shall be governed in accordance with
and governed by the internal laws of the State of Florida.

      12.   Incentive Stock Option Treatment. The terms of this Option shall be
interpreted in a manner consistent with the intent of the Company and the
Optionee that the Option qualify as an Incentive Stock Option under Section 422
of the Code. If any provision of the Plan or the Agreement shall be
impermissible in order for the Option to qualify as an Incentive Stock

                                        3

<PAGE>

Option, then the Option shall be construed and enforced as if such provision had
never been included in the Plan or the Option.

      13.   Interpretation/Provisions of Plan Control. This Agreement is subject
to all terms, conditions and provisions of the Plan, including, without
limitation, the amendment provisions thereof, and to such rules, regulations and
interpretations relating to the Plan adopted by the Committee or the Board as
may be in effect from time to time. If and to the extent that this Agreement
conflicts or is inconsistent with the terms, conditions and provisions of the
Plan, the Plan shall control, and this Agreement shall be deemed to be modified
accordingly. The Optionee accepts the Option subject to all the terms and
provisions of the Plan and this Agreement. The undersigned Optionee hereby
accepts as binding, conclusive and final all decisions or interpretation of the
Committee or the Board upon any questions arising under the Plan and this
Agreement.

      14.   Notices. Any notice under this Agreement shall be in writing and
shall be deemed to have been duly given when delivered personally or when
deposited in the United States mail, registered, postage prepaid, and addressed,
in the case of the Company, to the Company's Secretary at 5300 Broken Sound
Boulevard. NW, Boca Raton 33487, or if the Company should move its principal
office, to such principal office, and, in the case of the Optionee, to the
Optionee's last permanent address as shown on the Company's records, subject to
the right of either party to designate some other address at any time hereafter
in a notice satisfying the requirements of this Section.

      15.   Tax Consequences. Set forth below is a brief summary as of the date
of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE,
AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT
A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

            (a)   Exercise of Option. There will be no regular federal income
tax liability upon the exercise of the Option, although the excess, if any, of
the fair market value of the Shares on the date of exercise over the exercise
price will be treated as an adjustment to the alternative minimum tax for
federal tax purposes and may subject the Optionee to the alternative minimum tax
in the year of exercise.

            (b)   Disposition of Shares. If Shares transferred pursuant to the
Option are held for at least one year after exercise and are disposed of at
least two years after the date of grant, any gain realized on disposition of the
Shares will also be treated as long-term capital gain for federal income tax
purposes. If Shares purchased under an Option are disposed of within such
one-year period or within two years after the Date of Grant, any gain realized
on such disposition will be treated as compensation income (taxable at ordinary
income rates) to the extent of the difference between the exercise price and the
lesser of (1) the fair market value of the Shares on the date of exercise, or
(2) the sale price of the Shares.

            (c)   Notice of Disqualifying Disposition of Option Shares. If
Optionee sells or otherwise disposes of any of the Shares acquired pursuant to
the Option on or before the later of

                                        4

<PAGE>

(1) the date two years after the date of grant, (2) the date one year after the
date of exercise, the Optionee shall immediately notify the Company in writing
of such disposition. Optionee agrees that Optionee may be subject to the income
tax withholding by the Company on the compensation income recognized by the
Optionee from the early disposition by payment in cash or out of the current
earnings paid to the Optionee.

      IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the
20th day of July, 2001.

    For the purpose of this Agreement, a "Change of Control" shall also mean:

            (i)   The acquisition (other than from the Company), by any person,

that any person becoming a director subsequent to the date hereof whose
election, or nomination for election by the Company's stock-holders, was
approved by a vote of at least a majority of the directors then comprising the

                                 GARY O. MARINO

                                    AGREEMENT

1.    Grant of Option. RailAmerica, Inc. (the "Company") hereby grants, as of
      January 1, 2000 (the "Date of Grant") to Gary O. Marino (the "Optionee")
      an option (the "Option") to purchase up to 488,889 shares of the Company's
      Common Stock, $.001 par value per share (the "Shares"), at an exercise
      price per share equal to $9.00. The Option shall be subject to the terms
      and conditions set forth herein. The Option was issued pursuant to the
      Company's 1998 Executive Incentive Compensation Plan (the "Plan"), which
      is incorporated herein for all purposes. The Option is a Non-Qualified
      Stock Option, and not an Incentive Stock Option within the meaning of
      Section 422 of the Internal Revenue Code of 1986, as amended (the "Code").
      The Optionee hereby acknowledges receipt of a copy of the Plan and agrees
      to be bound by all of the terms and conditions hereof and thereof and all
      applicable laws and regulations.

2.    Definitions. Unless otherwise provided herein, terms used herein that are
      defined in the Plan and not defined herein shall have the meanings
      attributed thereto in the Plan.

3.    Exercise Schedule. Except as otherwise provided in Sections 6 or 9 of this
      Agreement, or in the Plan, the Option shall be exercisable in whole or in
      part and cumulatively according to the following schedule, provided that
      the Optionee has been continuously employed by the Company or a Subsidiary
      through and on the applicable Vesting Date:

</TABLE>

      Except as otherwise specifically provided herein, there shall be no
      proportionate or partial vesting in the periods prior to each Vesting
      Date, and all vesting shall occur only on the appropriate Vesting Date.
      Upon an Optionee's termination of employment with the Company and its
      Subsidiaries, any unvested portion of the Option shall terminate and be
      null and void.

4.    Method of Exercise. This Option shall he exercisable in whole or in part
      in accordance with the exercise schedule set forth in Section 3 hereof by
      written notice which shall state the election to exercise the Option, the
      number of Shares in respect of which the Option is being exercised, and
      such other representations and agreements as to the holder's investment
      intent with respect to such Shares as may be required by the Company. Such
      written notice shall be signed by the Optionee and shall be delivered in
      person or by

<PAGE>

      certified mail to the Secretary of the Company. The written notice shall
      be accompanied by payment of the exercise price. This Option shall be
      deemed to be exercised after both (a) receipt by the Company of such
      written notice accompanied by the exercise price and (b) arrangements that
      are satisfactory to the Company in its sole discretion have been made for
      Optionee's payment to the Company of the amount that is necessary to be
      withheld in accordance with applicable Federal or state withholding
      requirements. No Shares will be issued pursuant to the Option unless and
      until such issuance and such exercise shall comply with all relevant
      provisions of applicable law, including the requirements of any stock
      exchange upon which the Shares then may be traded.

5.    Method of Payment. Payment of the exercise price shall be by any of the
      following, or a combination thereof, at the election of the Optionee: (a)
      cash; (b) check; (c) with Shares that have been held by the Optionee for
      at least six months (or such other Shares as the Company determines will
      not cause the Company to recognize for financial accounting purposes a
      charge for compensation expense); or (d) such other consideration or in
      such other manner as may be determined by the Board or the Committee in
      its absolute discretion.

6.    Termination of Option.

      (a)   Any unexercised portion of the Option shall automatically and
      without notice terminate and become null and void at the time of the
      earliest to occur of:

            (i)   unless the Committee or the Board otherwise determines in
            writing in its sole discretion to provide for a longer period, three
            months after the date on which the Optionee's employment with the
            Company is terminated for any reason other than by reason of (A)
            Cause, which, solely for purposes of this Agreement, shall mean the
            termination of the Optionee's employment by reason of the Optionee's
            willful misconduct or gross negligence, (B) a mental or physical
            disability (within the meaning of Section 22(e) of the Internal
            Revenue Code) of the Optionee as determined by a medical doctor
            satisfactory to the Committee or the Board, or (C) death;

            (ii)  immediately upon the termination of the Optionee's employment
            with the Company for Cause;

            (iii) twelve months after the date on which the Optionee's
            employment with the Company is terminated by reason of a mental or
            physical disability (within the meaning of Section 22(e) of the
            Internal Revenue Code) as determined by a medical doctor
            satisfactory to the Committee or the Board;

            (iv)  twelve months after the date of termination of the Optionee's
            employment with the Company by reason of the death of the Optionee
            (or if later, three months after the date on which the Optionee
            shall die if such death shall occur during the one year period
            specified in paragraph (c) of this Section 5); or

            (v)   the tenth (10th) anniversary of the Date of Grant.

      (b)   The Committee or the Board, in its sole discretion may by giving
            written notice (the "cancellation notice") cancel, effective upon
            the date of the consummation of any Corporate Transaction described
            in Section 9(b)(ii) of the Plan or the consummation of any
            reorganization, merger, consolidation or other transaction in which
            the Company does not survive, any Option that remains unexercised on
            such date. Such cancellation notice shall be given a reasonable
            period of time prior to the proposed date of such cancellation and
            may be given either before or after approval of such corporate
            transaction, in order that the Optionee may have a reasonable period
            of time prior to the closing date of the corporate transaction
            within which to exercise the Option if and to the extent that it
            then is exercisable (including any portion of the Option that may
            become exercisable upon the closing date of such corporate
            transaction). The Optionee may condition his exercise of the Option
            upon the consummation of a transaction referred to in this Section
            6(b).

7.    Transferability. The Option granted hereby is not transferable otherwise
      than by will or under the applicable laws of descent and distribution, and
      during the lifetime of the Optionee the Option shall be exercisable only
      by the Optionee, or the Optionee's guardian or legal representative. In
      addition, the Option shall not be assigned, negotiated, pledged or
      hypothecated in any way (whether by operation of law or otherwise), and
      the Option shall not he subject to execution, attachment or similar
      process. Upon any attempt to transfer, assign, negotiate, pledge or
      hypothecate the Option, or in the event of any levy upon the Option by
      reason of any execution, attachment or similar process contrary to the
      provisions hereof, the Option shall immediately become null and void.

8.    No Rights of Stockholders. Neither the Optionee nor any personal
      representative (or beneficiary) shall be, or shall have any of the rights
      and privileges of, a stockholder of the Company with respect to any shares
      of Stock purchasable or issuable upon the exercise of the Option, in whole
      or in part, prior to the date of exercise of the Option.

9.    Acceleration of Exercisability of Option.

      (a)   This Option shall become immediately fully exercisable in the event
            of a "Change in Control", as defined in the Plan or in Exhibit "A",
            if any, attached hereto, or in the event that the Committee or the
            Board exercises its discretion to provide a cancellation notice with
            respect to the Option pursuant to Section 6(b) hereof.

      (b)   The Company may in its sole discretion accelerate the date on which
            this Option may be exercised and may accelerate the vesting of any
            Shares subject to this Option or previously acquired by the exercise
            of any Option.

10.   No Rights to Continued Employment. Neither the Option nor this Agreement
      shall confer upon the Optionee any right to continued employment or
      service with the Company.

11.   Amendment. The Company may from time to time amend, alter, suspend,
      discontinue or terminate the plan and may amend or alter the Option;
      provided, however, that no such amendment, alteration, suspension,
      discontinuance or termination of the Plan or the Option shall materially
      and adversely affect the rights or benefits of the Optionee under the
      Option without the consent of the Optionee.

12.   Withholding. If at anytime specified herein for the making of any issuance
      or delivery of the Option or Shares to the Optionee or beneficiary, any
      law or regulation of any governmental authority having jurisdiction in the
      premises shall require the Company to withhold, or to make any deduction
      for, any taxes or take any other action in connection with the issuance or
      delivery then to be made, such issuance or delivery shall be deferred
      until such withholding or deduction shall have been provided for by the
      Optionee or beneficiary, or other appropriate action shall have been
      taken.

13.   Law Governing. This Agreement shall be governed in accordance with and
      governed by the internal laws of the State of Delaware.

14.   Interpretation / Provisions of Plan Control. This Agreement is subject to
      all the terms, conditions and provisions of the Plan, including, without
      limitation, the amendment provisions thereof, and to such rules,
      regulations and interpretations relating to the Plan adopted by the
      Committee or the Board as may be in effect from time to time. If and to
      the extent that this Agreement conflicts or is inconsistent with the
      terms, conditions and provisions of the Plan, the Plan shall control, and
      this Agreement shall be deemed to be modified accordingly. The Optionee
      accepts the Option subject to all the terms and provisions of the Plan and
      this Agreement. The undersigned Optionee hereby accepts as binding,
      conclusive and final all decisions or interpretations of the Committee or
      the Board upon any questions arising under the Plan and this Agreement.

      deemed to have been duly given when delivered personally or when deposited
      in the United States mail, registered, postage prepaid, and addressed, in
      the case of the Company, to the Company's Secretary at 5300 Broken Sound

      (a)   Exercise of Option. There may be a regular federal income tax
            liability upon the exercise of the Option. The Optionee will be
            treated as having received compensation income (taxable at ordinary
            income tax rates) equal to the excess, if any, of the fair market
            value of the Shares on the date of exercise over the Exercise Price.
            If Optionee is an employee, the Company will he required to withhold
            from Optionee's compensation or collect from Optionee and pay to the
            applicable taxing authorities an amount equal to a percentage of
            this compensation income at the time of exercise.

      (b)   Disposition of Shares. If Shares are held for at least one year, any
            gain realized on disposition of the Shares will be treated as
            long-term capital gain for federal income tax purposes.

      IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the
20th day of July, 2001.

                        INCENTIVE STOCK OPTION AGREEMENT
                                       FOR
                                 GARY O. MARINO

                                    AGREEMENT

      1.    Grant of Option. RAILAMERICA. INC. (the "Company") hereby grants, as
of June 22, 2001 ("Date of Grant"), to Gary 0. Marino (the "Optionee") an option
(the "Option") to purchase up to 8.326 shares of the Company's Common Stock,
$.001 par value per share (the "Shares"), at an exercise price per share equal
to $12.01. The Option shall be subject to the terms and conditions set forth
herein. The Option was issued pursuant to the Company's 1998 Executive Incentive
Compensation Plan, as amended from time to time (the "Plan"), which is
incorporated herein for all purposes. The Option is an Incentive Stock Option,
and not a nonqualified stock option. The Optionee hereby acknowledges receipt of
a copy of the Plan and agrees to be bound by all of the terms and conditions
hereof and thereof and all applicable laws and regulations.

      2.    Definitions. Unless otherwise provided herein, terms used herein
that are defined in the Plan, and not defined herein shall have the meanings
attributed thereto in the Plan.

      3.    Exercise Schedule. Except as otherwise provided in Sections 6 or 12
of this Agreement, or in the Plan, the Option is exercisable in installments as
provided below, which shall be cumulative. To the extent that the Option has
become exercisable with respect to a percentage of Shares as provided below, the
Option may thereafter be exercised by the Optionee, in whole or in part at any
time or from time to time prior to the expiration of the Option as provided
herein. The following table indicates each date (the "Vesting Date") upon which
the Optionee shall be entitled to exercise the Option with respect to the number
of Shares granted as indicated beside the date, provided that the Optionee has
been continuously employed by the Company or a Subsidiary through and on the
applicable Vesting Date:

<TABLE>
<CAPTION>

<S>                    <C>
  -0- Shares           N/A
  -0- Shares           N/A
  8.326 Shares         June 22, 2003
</TABLE>

      Except as otherwise specifically provided herein, there shall be no
proportionate or partial vesting in the periods prior to each Vesting Date, and
all vesting shall occur only on the appropriate Vesting Date. Upon an Optionee's
termination of employment with the Company and its Subsidiaries, any unvested
portion of the Option shall terminate and be null and void.

      4.    Method of Exercise. The vested portion of this Option shall be
exercisable in whole or in part in accordance with the exercise schedule set
forth in Section 3 hereof by written notice which shall state the election to
exercise the Option, the number of Shares in respect of

                                       1

<PAGE>

which the Option is being exercised, and such other representations and
agreements as to the holder's investment intent with respect to such Shares as
may be required by the Company pursuant to the provisions of the Plan. Such
written notice shall be signed by the Optionee and shall be delivered in person
or by certified mail to the Secretary of the Company. The written notice shall
be accompanied by payment of the exercise price. This Option shall be deemed to
be exercised after both (a) receipt by the Company of such written notice
accompanied by the exercise price and (b) arrangements that are satisfactory to
the Committee in its sole discretion have been made for Optionee's payment to
the Company of the amount, if any, that is necessary to be withheld in
accordance with applicable Federal or state withholding requirements. No Shares
will be issued pursuant to the Option unless and until such issuance and such
exercise shall comply with all relevant provisions of applicable law, including
the requirements of any stock exchange upon which the Shares then may be traded.

      5.    Method of Payment. Payment of the exercise price shall be by any of
the following, or a combination thereof, at the election of the Optionee: (a)
cash; (b) check; or (c) with Shares that have been held by the Optionee for at
least 6 months (or such other Shares as the Company determines will not cause
the Company to recognize for financial accounting purposes a charge for
compensation expense), or (d) such other consideration or in such other manner
as may be determined by the Board or the Committee in its absolute discretion.

      6.    Termination of Option.

            (a)   Any unexercised portion of the Option shall automatically and
without notice terminate and become null and void at the time of the earliest to
occur of:

                  (i)   three months after the date on which the Optionee's
employment is terminated other than by reason of (A) Cause, which, solely for
purposes of this Plan, shall mean the termination of the Optionee's employment
by reason of the Optionee's willful misconduct or gross negligence. (B) a mental
or physical disability (within the meaning of Internal Revenue Code Section
22(e)) of the Optionee as determined by a medical doctor satisfactory to the
Committee, or (C) death of the Optionee;

                  (ii)  immediately upon the termination of the Optionee's
employment for Cause;

                  (iii) twelve months after the date on which the Optionee's
employment is terminated by reason of a mental or physical disability (within
the meaning of Section 22(e) of the Code) as determined by a medical doctor
satisfactory to the Committee;

                  (iv)  (A) twelve months after the date of termination of the
Optionee's employment by reason of the death of the Optionee, or, if later, (B)
three months after the date on which the Optionee shall die if such death shall
occur daring the one year period specified in Subsection 6(a)(iii) hereof; or

                  (v)   the tenth anniversary of the date as of which the Option
is granted.

                                       2

<PAGE>

            (b)   To the extent not previously exercised. (i) the Option shall
terminate immediately in the event of (1) the liquidation or dissolution of the
Company, or (2) any reorganization, merger, consolidation or other form of
corporate transaction in which the Company does not survive, unless the
successor corporation, or a parent or subsidiary of such successor corporation,
assumes the Option or substitutes an equivalent option or right pursuant to
Section 10(c) of the Plan, and (ii) the Committee or the Board in its sole
discretion may by written notice ("cancellation notice") cancel, effective upon
the consummation of any corporate transaction described in Subsection 9(b)(i) of
the Plan in which the Company does survive, the Option (or portion thereof) that
remains unexercised on such date. The Committee or the Board shall give written
notice of any proposed transaction referred to in this Section 6(b) a reasonable
period of time prior to the closing date for such transaction (which notice may
be given either before or after approval of such transaction), in order that
Optionee may have a reasonable period of time prior to the closing date of such
transaction within which to exercise the Option if and to the extent that it
then is exercisable (including any portion of the Option that may become
exercisable upon the closing date of such transaction). The Optionee may
condition his exercise of the Option upon the consummation of a transaction
referred to in this Section 6(b).

      7.    Transferability. The Option is not transferable otherwise than by
will or the laws of descent and distribution, and during the lifetime of the
Optionee the Option shall be exercisable only by the Optionee. The terms of this
Option shall be binding upon the executors, administrators, heirs, successors
and assigns of the Optionee.

      8.    No Rights of Stockholders. Neither the Optionee nor any personal
representative (or beneficiary) shall be, or shall have any of the rights and
privileges of, a stockholder of the Company with respect to any shares of Stock
purchasable or issuable upon the exercise of the Option, in whole or in part,
prior to the date of exercise of the Option.

      9.    Acceleration of Exercisability of Option. This Option shall become
immediately fully exercisable in the event of a "Change in Control", as defined
in the Plan or in Exhibit "A", if any, attached hereto, or in the event that the
Committee or the Board exercises its discretion to provide a cancellation notice
with respect to the Option pursuant to Section 6(b) hereof. The Company may in
its sole discretion accelerate the date on which this Option may be exercised
and may accelerate the vesting of any Shares subject to this Option or
previously acquired by the exercise of any Option.

      10.   No Right to Continued Employment. Neither the Option nor this
Agreement shall confer upon the Optionee any right to continued employment or
service with the Company.

      11.   Law Governing. This Agreement shall be governed in accordance with
and governed by the internal laws of the State of Florida.

      12.   Incentive Stock Option Treatment. The terms of this Option shall be
interpreted in a manner consistent with the intent of the Company and the
Optionee that the Option qualify as an Incentive Stock Option under Section 422
of the Code. If any provision of the Plan or the Agreement shall be
impermissible in order for the Option to qualify as an Incentive Stock

                                       3
<PAGE>

Option, then the Option shall be construed and enforced as if such provision had
never been included in the Plan or the Option.

      13.   Interpretation/Provisions of Plan Control. This Agreement is subject
to all the terms, conditions and provisions of the Plan, including, without
limitation, the amendment provisions thereof, and to such rules, regulations and
interpretations relating to the Plan adopted by the Committee or the Board as
may be in effect from time to time. If and to the extent that this Agreement
conflicts or is inconsistent with the terms, conditions and provisions of the
Plan, the Plan shall control, and this Agreement shall be deemed to be modified
accordingly. The Optionee accepts the Option subject to all the terms and
provisions of the Plan and this Agreement. The undersigned Optionee hereby
accepts as binding, conclusive and final all decisions or interpretations of the
Committee or the Board upon any questions arising under the plan and this
Agreement.

      14.   Notices. Any notice under this Agreement shall be in writing and
shall be deemed to have been duly given when delivered personally or when
deposited in the United States mail, registered, postage prepaid, and addressed,
in the case of the Company, to the Company's Secretary at 5300 Broken Sound
Boulevard, NW, Boca Raton 33487, or if the Company should move its principal
office, to such principal office, and, in the case of the Optionee, to the
Optionee's last permanent address as shown on the Company's records, subject to
the right of either party to designate some other address at any time hereafter
in a notice satisfying the requirements of this Section.

      15.   Tax Consequences. Set forth below is a brief summary as of the date
of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE,
AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD
CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

            (a)   Exercise of Option. There will be no regular federal income
tax liability upon the exercise of the Option, although the excess, if any, of
the fair market value of the Shares on the date of exercise over the exercise
price will be treated as an adjustment to the alternative minimum tax for
federal tax purposes and may subject the Optionee to the alternative minimum tax
in the year of exercise.

            (b)   Disposition of Shares. If Shares transferred pursuant to the
Option are held for at least one year after exercise and are disposed of at
least two years after the date of grant, any gain realized on disposition of the
Shares will also be treated as long-term capital gain for federal income tax
purposes. If Shares purchased under an Option are disposed of within such
one-year period or within two years after the Date of Grant, any gain realized
on such disposition will be treated as compensation income (taxable at ordinary
income rates to the extent of the difference between the exercise price and the
lesser of (1) the fair market value of the Shares on the date of exercise, or
(2) the sale price of the Shares.

            (c)   Notice of Disqualifying Disposition of Option Shares. If
Optionee sells or otherwise disposes of any of the Shares acquired pursuant to
the Option on or before the later of

                                       4

<PAGE>

(1) the date two years after the date of grant, (2) the date one year after the
date of exercise, the Optionee shall immediately notify the Company in writing
of such disposition. Optionee agrees that Optionee may be subject to the income
tax withholding by the Company on the compensation income recognized by the
Optionee from the early disposition by payment in cash or out of the current
earnings paid to the Optionee.

      IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the
20th day of July, 2001.

            period of time prior to the proposed date of such cancellation and
            may be given either before or after approval of such corporate
            transaction, in order that the Optionee may have a reasonable period

      (a)   Exercise of Option. There may be a regular federal income tax
            liability upon the exercise of the Option. The Optionee will be
            treated as having received compensation income (taxable at ordinary
            income tax rates) equal to the excess, if any, of the fair market
            value of the Shares on the date of exercise over the Exercise Price.
            If Optionee is an employee, the Company will be required to withhold
            from Optionee's compensation or collect from Optionee and pay to the
            applicable taxing authorities an amount equal to a percentage of
            this compensation income at the time of exercise.

      (b)   Disposition of Shares. If Shares are held for at least one year,
            any gain realized on disposition of the Shares will be treated as
            long-term capital gain for federal income tax purposes.

      IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the
20th day of July, 2001.

("cancellation notice") cancel effective upon the consummation of any corporate
transaction described in Subsection 9(b)(i) of the Plan in which the Company

date. The Committee or the Board shall give written notice of any proposed
transaction referred to in this Section 6(b) a reasonable period of time prior
to the closing date for such transaction (which notice may be given, either
before or after approval of such transaction), in order that Optionee may have a

immediately fully exercisable in the event of a "Change in Control", as defined
in the Plan or in Exhibit "A", if any attached hereto, or in the event that the
Committee or the Board exercises its discretion to provide a cancellation notice
with respect to the Option pursuant to Section 6(b) hereof. The Company may in
its sole discretion accelerate the date on which this Option may be exercised

Agreement shall confer upon the Optionee any right to continued employment or
service with the Company.

and provisions of the Plan and this Agreement. The undersigned Optionee hereby
accepts as binding, conclusive and final all decisions or interpretations of the

      14.   Notices. Any notice under this Agreement shall be in writing and
shall be deemed to have been duly given when delivered personally or when
deposited in the United States mail, registered, postage prepaid, and addressed,
in the case of the Company, to the Company's Secretary at 5300 Broken Sound

      15.   Tax Consequences. Set forth below is a brief summary as of the date
of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE,
AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT
A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

            (a)   Exercise of Option. There will be no regular federal income
tax liability upon the exercise of the Option, although the excess, if any, of
the fair market value of the Shares on the date of exercise over the exercise
price will be treated as an adjustment to the alternative minimum tax for
federal tax purposes and may subject the Optionee to the alternative minimum tax
in the year of exercise.

            (b)   Disposition of Shares. If Shares transferred pursuant to the
Option are held for at least one year after exercise and are disposed of at
least two years after the date of grant, any gain realized on disposition of the
Shares will also be treated as long-term capital gain for federal income tax
purposes. If Shares purchased under an Option are disposed of within such
one-year period or within two years after the Date of Grant, any gain realized
on such disposition will be treated as compensation income (taxable at ordinary
income rates) to the extent of the difference between the exercise price and the
lesser of (1) the fair market value of the Shares on the date of exercise, or
(2) the sale price of the Shares.

            (c)   Notice of Disqualifying Disposition of Option Shares. If
Optionee sells or otherwise disposes of any of the Shares acquired pursuant to
the Option on or before the later of (1) the date two years after the date of
grant, (2) the date one year after the date of exercise, the Optionee shall
immediately notify the Company in writing of such disposition, Optionee agrees
that Optionee may be subject to the income tax withholding by the Company on the

                                       4
<PAGE>

compensation income recognized by the Optionee from the early disposition by
payment in cash or out of the current earnings paid to the Optionee.

      IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the
20th day of June, 2002.

OF THE COMPANY. Subject to Section 4 hereof, the Company shall indemnify and
hold harmless the Indemnitee from and against any and all expenses (including

provided that (i) the Indemnitee acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the Company
and (ii) no indemnification shall be made under this Section 2 in respect of any
claim, issue or matter as to which the Indemnitee shall have been adjudged to be
liable to the Company for misconduct in the performance of his duty to the
Company unless, and only to the extent that, the court in which such proceeding
was brought (or any other court of competent jurisdiction) shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, the Indemnitee is fairly and reasonably entitled to
indemnity for such expenses which such court shall deem proper.

      SECTION 3. INDEMNIFICATION FOLLOWING ADJUDICATION OF NEGLIGENCE. The
Indemnitee shall be entitled to the indemnification provided in Sections 1 and 2
hereof in accordance with the terms hereof regardless of any adjudication that
the Indemnitee was liable for negligence, gross negligence or recklessness (but
not willful misconduct) in the performance of his duty to the Company; provided,
however, that the Indemnitee acted in good faith and in a manner he believed to
be in the best interests of the Company.

      SECTION 4. AUTHORIZATION OF INDEMNIFICATION.

      4.1.  Procedure for Determination Regarding Indemnification. Any
indemnification under Sections 1, 2 and 3 hereof (unless ordered by a court)
shall be made by the Company only as authorized in the specific case upon a
determination (the "Determination") that indemnification of the Indemnitee is
proper in the circumstances because the Indemnitee has met the applicable
standard of conduct set forth in Section 1, 2 or 3 hereof, as the case may be.
Subject to Sections 5.6, 5.7 and 8 of this Agreement, the Determination shall be
made in the following order of preference:

                  (1)   first, by the Company's Board of Directors (the "Board")
by majority vote or consent of a quorum consisting of directors ("Disinterested
Directors")

                                        2

<PAGE>

who are not, at the time of the Determination, named parties to such action,
suit or proceeding; or

                  (2)   next, if such a quorum of Disinterested Directors cannot
be obtained by majority vote or consent of a committee duly designated by the
Board (in which designation all directors, whether or not Disinterested
Directors, may participate) consisting solely of two or more Disinterested
Directors; or

                  (3)   next, if such a committee cannot be designated, by any
independent legal counsel (who may be any outside counsel regularly employed by
the Company) in a written opinion; or

                  (4)   next, if such legal counsel determination cannot be
obtained, by vote or consent of the holders of a majority of the Company's
common stock.

      4.2.  No Presumptions. The termination of any action, suit or proceeding
by judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the Indemnitee
did not act in good faith and in a manner that he reasonably believed to be in
or not opposed to the best interests of the Company, and with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

      4.3.  Benefit Plan Conduct. The Indemnitee's conduct with respect to an '
employee benefit plan for a purpose he reasonably believed to be in the
interests of the participants in and beneficiaries of the plan shall be deemed
to be conduct that the Indemnitee reasonably believed to be not opposed to the
best interests of the Company.

      4.4.  Reliance as Safe Harbor. For purposes of any Determination
hereunder, the Indemnitee shall be deemed to have acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Company, or, with respect to any criminal action or proceeding, to have had
no reasonable cause to believe his conduct was unlawful, if his action is based
on (i) the records or books of account of the Company or another enterprise,
including financial statements, (ii) information supplied to him by the officers
of the Company or another enterprise in the course of their duties, (iii) the
advice of legal counsel for the Company or another enterprise, or (iv)
information or records given or reports made to the Company or another
enterprise by an independent certified public accountant or by an appraiser or
other expert selected with reasonable care by the Company or another enterprise.
The term "another enterprise" as used in this Section 4.4 shall mean any other
corporation or any partnership, joint venture, trust, employee benefit plan or
other enterprise of which the Indemnitee is or was serving at the request of the
Company as an officer, director, consultant, partner, trustee, employee or
agent. The provisions of this Section 4.4 shall not be deemed to be exclusive or
to limit in any way the other circumstances it which the Indemnitee may be
deemed to have met the applicable standard of conduct set forth in Sections 1, 2
or 3 hereof, as the case may be.

                                        3

      4.5.  Success on Merits or Otherwise. Notwithstanding any other provision
of this Agreement, to the extent that the Indemnitee has been successful on the
merits or otherwise in defense of any action, suit or proceeding described in
Section 1 or 2 hereof, or in defense of any claim, issue or matter therein, he
shall be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection with the investigation, defense,
settlement or appeal thereof. For purposes of this Section 4.5, the term
"successful on the merits or otherwise" shall include, but not be limited to,
(i) any termination, withdrawal, or dismissal (with or without prejudice) of any
claim, action, suit or proceeding against the Indemnitee without any express
finding of liability or guilt against him, (ii) the expiration of 120 days after
the making of any claim or threat of an action, suit or proceeding without the
institution of the same and without any promise or payment made to induce a
settlement, or (iii) the settlement of any action, suit or proceeding under
Section 1, 2 or 3 hereof pursuant to which the Indemnitee pays less than
$10,000.

      4.6.  Partial Indemnification or Reimbursement. If the Indemnitee is
entitled under any provision of this Agreement to indemnification and/or
reimbursement by the Company for some or a portion of the clams, damages,
expenses (including attorneys' fees), judgments, fines or amounts paid in
settlement by the Indemnitee in connection with the investigation, defense,
settlement or appeal of any action specified in Section 1, 2 or 3 hereof, but
not, however, for the total amount thereof, the Company shall nevertheless
indemnify and/or reimburse the Indemnitee for the portion thereof to which the
Indemnitee is entitled. The party or parties making the Determination shall
determine the portion (if less than all) of such claims, damages, expenses
(including attorneys' fees), judgments, fines or amounts paid in settlement for
which the Indemnitee is entitled to Indemnification and/or reimbursement under
this Agreement.

      SECTION 5. PROCEDURES FOR DETERMINATION OF WHETHER STANDARDS HAVE BEEN
SATISFIED.

      5.1.  Costs. All costs of making The Determination required by Section 4
hereof shall be borne solely by the Company, including, but not limited to, the
costs of legal counsel, proxy solicitations and judicial determinations. The
Company shall also be solely responsible for paying (i) all reasonable expenses
incurred by the Indemnitee to enforce this Agreement, including, but not limited
to, the costs incurred by the Indemnitee to obtain court-ordered indemnification
pursuant to Section 8 hereof, regardless of the outcome of any such application
or proceeding, and (ii) all costs of defending any suits or proceedings
challenging payments to the Indemnitee under this Agreement.

      5.2.  Timing of the Determination. The Company shall use its best efforts
to make the Determination contemplated by Section 4 hereof promptly. In
addition, the Company agrees:

            (a)   if the Determination is to be made by the Board or a committee
thereof, such Determination shall be made not later than 45 days after a written
request for a Determination (a "Request") is delivered to the Company by the
Indemnitee;

                                        4

<PAGE>

            (b)   if the Determination is to be made by independent legal
counsel, such Determination shall be made not later than 45 days after a Request
is delivered to the Company by the Indemnitee; and

            (c)   if the Determination is to be made by the stockholders of the
Company, such Determination shall be made not later than 90 days after a Request
is delivered to the Company by the Indemnitee.

The failure to make a Determination within the above-specified time period shall
constitute a Determination approving full indemnification or reimbursement of
the Indemnitee. Notwithstanding anything herein to the contrary, a Determination
may be made in advance of (i) the Indemnitee's payment (or incurring) of
expenses with respect to which indemnification or reimbursement is sought,
and/or (ii) final disposition of the action, suit or proceeding with respect to
which indemnification or reimbursement is sought.

      5.3.  Reasonableness of Expenses. The evaluation and finding as to the
reasonableness of expenses incurred by the Indemnitee for purposes of this
Agreement shall be made (in the following order of preference) within 45 days of
the Indemnitee's delivery to the Company of a Request that includes a reasonable
accounting of expenses incurred:

            (a)   first, by the Board by a majority vote or consent of a quorum
consisting of Disinterested Directors; or

            (b)   next, if a quorum cannot be obtained under subdivision (a), by
majority vote or consent of a committee duly designated by the Board (in which
designation all directors, whether or not Disinterested Directors, may
participate), consisting solely of two or more Disinterested Directors; or

            (c)   next, if such a committee cannot be designated, by any
independent legal counsel (who may be any outside counsel regularly employed by
the Company); or

            (d)   next, if such legal counsel determination cannot be obtained,
by vote or consent of the holders of a majority of the Company's common stock.

All expenses shall be considered reasonable for purposes of this Agreement if
the finding contemplated by this Section 5.3 is not made within the prescribed
time. The finding required by this Section 5.3 may be made in advance of the
payment (or incurring) of the expenses for which indemnification or
reimbursement is sought.

      5.4.  Payment of Indemnified Amount. Immediately following a Determination
that the Indemnitee has met the applicable standard of conduct set forth in
Section 1, 2 or 3 hereof, as the case may be, and the finding of reasonableness

prescribed for making such determination(s), the Company shall pay to the
Indemnitee in cash the amount to which the Indemnitee is

                                        5

<PAGE>

the Delaware General Corporation law, the Indemnitee and any other stockholder
who is a party to the proceeding for which indemnification or reimbursement is
sought shall be entitled to vote on say Determination to be made by the

hereof. In addition, in connection with each meeting at which a stockholder

statement relating to the proposal to indemnify or reimburse the Indemnitee
shall not include a recommendation against indemnification or reimbursement.

      5.6.  Selection of Independent Legal Counsel. If the Determination
required under Section 4.1 or 5.7 or the evaluation of reasonableness of
expenses under Section 5.3 is to be made by independent legal counsel, such
counsel shall be selected by the Indemnitee with the approval of the Board,
which approval shall not be unreasonably withheld. The fees and expenses
incurred by counsel in making any Determination (including Determinations
pursuant to Section 5.8 hereof) shall be borne solely by the Company regardless
of the results of any Determination and, if requested by counsel, the Company
shall give such counsel an appropriate written agreement with respect to the
payment of their fees and expenses and such other matters as may be reasonably
requested by counsel.

      5.7.  Right of Indemnitee to Appeal an Adverse Determination by Board. If

hereof, upon the written, request of the Indemnitee, the Company shall cause a
new Determination to be made by any independent legal counsel (who may be any
outside counsel regularly employed by the Company). If a Determination is made
by such legal counsel that the Indemnitee did not meet such applicable standard
of conduct, upon the written request of the Indemnitee and the Indemnitee's
delivery of $500 to the Company, the Company shall cause a new Determination to
be made by the Company's stockholders at the next regular or special meeting of
stockholders. Subject to Section 8 hereof, such Determination by the Company's
stockholders shall be binding and conclusive for all purposes of this Agreement.

      5.8.  Right of Indemnitee To Select Forum For Determination. If, at any
time subsequent to the date of this Agreement, "Continuing Directors" do not
constitute a majority of the members of the Board, or there is otherwise a
change in control of the Company (as contemplated by Item 403(c) of Regulation
S-K), then upon the request of the Indemnitee, the Company shall cause the
Determination required by Section 4.1 hereof and/or the finding repaired by
Section 5.3 hereof to be made by independent legal counsel selected by the
Indemnitee and approved by the Board (which approval shall not be unreasonably
withheld), which counsel shall be deemed to satisfy the requirements of

                                        6

<PAGE>

clause (3) of Section 4.1 hereof and/or clause (c) of Section 5.3. If none of
the legal counsel selected by the Indemnitee are willing and/or able to make the
Determination or the finding, then the Company shall cause the Determination to
be made by a majority vote or consent of a Board committee consisting solely of
Continuing Directors. For purposes of this Agreement, a "Continuing Director"

nominated to serve as a member of the Board by a majority of the then
Continuing Directors.

the Indemnitee and his representatives ample opportunity to present evidence of

together with other information relating to any requested Determination. The
Company shall also afford the Indemnitee the reasonable opportunity to include
such evidence and information in any Company proxy statement relating to a
stockholder Determination.

described in Section 2 hereof, the Company shall cause its counsel to use its
best efforts to obtain from the Court in which such action or suit was
brought(i) an express adjudication whether the Indemnitee is liable for
negligence or misconduct in the performance of his duty to the Company, and, if
the Indemnitee is so liable, (ii) a determination whether and to what extent,
despite the adjudication of liability but in view of all the circumstances of
the case (including this Agreement), the Indemnitee is fairly and reasonably
entitled to indemnification.

      SECTION 6. SCOPE OF INDEMNITY. Subject to the limitations set forth in
Sections 1 and 2 hereof, the actions, suits and proceedings described in
Sections 1 and 2 hereof shall include, for purposes of this Agreement, any
actions that involve, directly or indirectly, activities of the Indemnitee both

limited to, actions or proceedings involving (i) compensation paid to the

Agreement in any applicable law, statute at rule or the Company's Certificate of
Incorporation expands the power of the Company to indemnify the Indemnitee, such

obligations under this Agreement. If any change in any applicable law, statute
or rule or the Company's Certificate of Incorporation narrows the right of the

of Incorporation to be applied to this Agreement, shall have no effect on this
Agreement or the parties' rights and obligations thereunder.

AT THE COMPANY                                            FOR IMMEDIATE RELEASE

               RAILAMERICA ANNOUNCES RETIREMENT OF GARY O. MARINO

BOCA RATON, FL - APRIL 7 - RailAmerica announced today that President and Chief
Executive Officer (CEO) Gary O. Marino has decided to retire from the Company
effective immediately. Mr. Marino, age 59, had served as RailAmerica's Chairman
of the Board of Directors since the Company's formation in 1992. He also served
as CEO since 1994 and as President since 1996. Under his leadership, RailAmerica
grew from a private company owning one railroad, with revenues of approximately
$1 million to a New York Stock Exchange listed public company owning 47
railroads with revenues of approximately $360 million.

         "Gary has been a dedicated leader of RailAmerica since the Company was
founded and has achieved a long list of enviable accomplishments," said William
(Gus) Pagonis, Chairman of RailAmerica's Board of Directors. "The Company is
highly appreciative of Gary's leadership and vision in helping transform the
Company from one short line railroad to a railroad holding company that is one
of the largest in North America. We thank him for his dedicated service and wish
him well in his future endeavors."

         "With the recent announcement of the execution of an agreement to sell
Freight Australia," said Gary Marino, "my work at RailAmerica is now complete.
The Company is well positioned for future, sustained growth and the proceeds to
be received from the pending Australia railroad sale will further strengthen the
balance sheet and provide the capital for the Company to bolster its strong
footprint in the North American railroad industry. I enjoyed tremendously
helping to build RailAmerica over the last 18 years. I could not have done it
without the dedicated service from a very talented, motivated management team
and staff, and a supportive Board of Directors. I expect to now have time to
pursue other projects that interest me and to focus on other personal
priorities."

         "The Board will commence a search for a new President and CEO. In the
interim, we expect that our strong management team led by Donald D. Redfearn,
Acting President, Michael Howe, CFO, and Joe Conklin, COO will continue to
effectively manage the business. I will be actively involved in helping them
manage the Company, and the Board will continue to provide oversight, governance
and support," stated William G. Pagonis.

         In connection with Mr. Marino's retirement, the Company will record a
charge of approximately $0.18 - $0.20 per share in the second quarter for his
retirement benefits. Approximately 50% of the charge relates to non-cash items
for the extension of his stock options and the vesting of certain equity awards.

                             AMENDMENT NO. 3 TO THE
                           MASTER PRODUCTION AGREEMENT

                           EXECUTED PREVIOUSLY BETWEEN

                               R&G MORTGAGE CORP.

                                       AND

                          GUAYNABO FEDERAL SAVINGS BANK
                      (NOW R&G PREMIER BANK OF PUERTO RICO)

         This Amendment No. 3 dated January 1, 2004 (the "Amendment"), hereby
amends the Master Production Agreement, dated February 16, 1990 by and between
R&G Mortgage Corp., a mortgage banking firm organized under the laws of the
Commonwealth of Puerto Rico ("R&G Mortgage"), and R&G Premier Bank of Puerto
Rico, a Puerto Rico chartered commercial bank which was formerly known as
Guaynabo Federal Savings Bank ("Premier Bank"), as amended on August 30, 1991
and March 31, 1995 (as amended, the "Agreement").

                                   WITNESSETH

         WHEREAS, from time to time in the conduct of their respective
businesses, Premier Bank has sold and intends to continue to sell mortgage loans
to third parties that were previously originated (and will continue to be
originated) for its portfolio by R&G Mortgage, and in connection with such
sales, R&G Mortgage contractually has agreed and will continue to agree to (i)
repurchase loans which either become non-performing or go into foreclosure, or
which violate representations, warranties or covenants set forth in the
operative sales agreements, or (ii) remit payments to keep such mortgage loans
current as to principal and/or interest, in accordance with the operative sales
agreements;

         WHEREAS, in consideration of the obligations it has been incurring and
will continue to incur in connection with commitments undertaken in certain
Premier Bank loan sale agreements with unaffiliated third parties, the Board of
Directors of Premier Bank, believes it to be appropriate to compensate R&G
Mortgage for the aforementioned undertakings;

         WHEREAS, the Ancillary Agreements Committee has considered the
compensation proposed to be paid to R&G Mortgage pursuant to this Amendment,
together with the compensation already provided under the Agreement, against the
totality of the services performed and to be performed by R&G Mortgage, and
mindful of the provisions of Section 23B of the Federal Reserve Act, has
determined that the Agreement, as hereby amended, reflects terms and
circumstances that, in good faith in the absence of comparable transactions,
would be offered to, or would apply to, non-affiliated companies; and

         WHEREAS, the Board of Directors of Premier Bank, pursuant to the
recommendation of its Ancillary Agreements Committee, hereby resolves to approve
the Amendment, whereby

<PAGE>

R&G Mortgage will be entitled to 50% of the excess service fee generated on all
loans that were originally originated by R&G Mortgage for Premier Bank, upon
sale by Premier Bank to an unaffiliated third party, with such fee to be paid at
the time of sale of any such loans, effective as of the date of this Amendment.

         NOW, THEREFORE, intending to legally bound, the parties hereby agree to
amend the Agreement as follows:

I.   A new Section 3.1 is hereby added to the Agreement and states in its
entirety as follows (with defined terms used as they appear in the Agreement):

         3.1      ADDITIONAL FEE. In connection with the sale of loans by Bank
to unaffiliated third parties which have been referred and originated by R&G
hereunder, pursuant to which R&G becomes contractually obligated to (i)
repurchase loans which either become non-performing or go into foreclosure, or
which violate representations, warranties or covenants set forth in the
operative sales agreements, or (ii) remit payments to keep such mortgage loans
current as to principal and/or interest, in accordance with the operative sales
agreements, Bank agrees to allocate to R&G, at the time of such sales, 50% of
the excess service fees generated in connection with any such sale.

II.      The rest, residue and remainder of the Agreement is hereby
reaffirmed, ratified and incorporated as if fully set forth herein.

         IN WITNESS WHEREOF, the parties hereto have duly executed this
Amendment to the Agreement this 1st day of January, 2004.

                                                 R&G PREMIER BANK OF PUERTO RICO
