         Re:      Amended and Restated Employment Agreement, dated Jan. 1, 2000
                  (the "Employment Agreement")

Dear John:

         It is my understanding that you and the Company have recently agreed
to modify the terms of your employment with RailWorks Corporation. Set forth
below are the changes to the Employment Agreement that reflect these
modifications:

1.       The text of Section 1, Employment, is replaced in its entirety by the
         following:

          "Subject to the terms hereof, Employer will employ Employee and
          Employee hereby accepts such employment. The Employee shall serve as
          Director, Business Development.

          Subject to the terms and conditions of this Agreement, Employee will
          devote a mutually agreeable portion of his business time and efforts
          in the rail and rail supply industries to the performance of his job
          as Director, Business Development, of the Employer; subject to the
          direction of the Employer's Vice President, Corporate Business
          Development."

2.       The text of paragraph 3.1(a), Salary, is replaced in its entirety by
         the following:

         "As of August 1, 2000, Employee will be paid a salary (the "Base
         Salary") of Fifty Thousand Dollars ($50,000.00) per annum, less
         deductions and withholdings required by applicable law. The Base
         Salary will be paid to Employee in equal monthly installments (or on
         such more frequent basis as other executives of Employer are
         compensated). The Base Salary shall be reviewed by Employer on at
         least an annual basis after August 1, 2000, but may not be decreased
         below the Base Salary set forth above as a result of such review."

3.       Paragraph 3.1(b) is deleted in its entirety.

         Except as set forth above, all terms and conditions of the Employment
Agreement remain unchanged and in full force and effect.

                  For purposes of this Agreement, a "Change of Control" shall
                  be deemed to have occurred if (A) any "person" (as such term

                  of Employer outstanding immediately prior thereto continuing
                  to represent (either by remaining outstanding or by being
                  convened into Voting Securities of the surviving entity) at
                  least 50% of the total voting power represented by the Voting
                  Securities of Employer or such surviving entity

                  surviving entity is composed of members from the Board of
                  Directors of Employer; (D) the stockholders of Employer

                  similar committee of the Board of Directors; or

         (iv)     After December 31, 2001, this Agreement shall continue upon a
                  year-to-year basis unless terminated by either the Employer
                  or the Employee upon ninety days (90) written notice to the
                  other before January 1 of the next year.

                  required by applicable law. The Base Salary will be paid to
                  Employee in equal monthly installments (or on such more
                  frequent basis as other executives of Employer are
                  compensated). The Base Salary shall be reviewed by Employer

Except upon termination by the Employer of the employment of the Employee

Performance Bonus would have been paid had Employee continued his employment
hereunder. In addition, the Employee and his eligible dependents shall be

benefits specified hereunder for a period of twelve (12) months following the
Termination Date (the "Continuation Period") and following such time period,

and (B) the life insurance benefits specified hereinabove for the period of the
Continuation Period.

         (i)      Immediately upon a Change in Control or upon termination of
                  this Agreement, pursuant to the provisions of Sections 2 (i)
                  or (iii) hereof, any stock grants or options previously
                  awarded to the Employee, either by this Agreement or
                  otherwise, shall fully and completely vest and the Employee
                  shall be able to retain or obtain as the case may be, such
                  stock, as though there was no vesting period or criteria of
                  any kind or nature, with respect to such stock. If stock
                  options have previously been awarded to the Employee,
                  notwithstanding any terms and conditions of such award or any
                  plan pursuant to which such stock options were awarded, the
                  Employee or his authorized representative shall have a period
                  of three (3) months from the Termination Date to exercise
                  any or all of such stock options and acquire for his own
                  benefit the shares of stock covered by such stock options.

                  the Termination Date, stock grants or options shall be
                  forfeited upon such termination; provided that the Employee
                  shall be able to retain or exercise any rights for a period
                  of one (1) month after the Termination Date, notwithstanding
                  the terms and provisions of such stock options awarded or the
                  plan under which they were awarded, with respect to any
                  shares of stock granted or shares of stock covered by stock
                  options that have fully vested as of the Termination Date.

upon a Change of Control, any balance of the Loan, together with any accrued
but unpaid interest thereon to the date of forgiveness, shall be forgiven
automatically without further action by the Employer or the Employee, and in
addition, Employer shall pay to Employee an amount equal to the difference
between (i) the actual federal, state and local income taxes payable by
Employee for the year in which the Loan is forgiven, including for the purpose
of such calculation the taxes resulting from the inclusion in Employee's income
of the gross up payments under this Section and (ii) the amount of such taxes
which would have been paid by Employee had the Loan not been forgiven. In the
event it is determined that any payment hereunder is an "excess parachute
payment" as defined in Section 280G of the Internal Revenue Code of 1986, as
amended, the Employer shall reimburse Employee for the excise tax imposed under
such section and in addition shall pay Employee an amount equal to the
additional federal, state and local income taxes payable or paid by Employee
for the year in which such payment is made to Employee, including for the
purpose of such calculation, the taxes resulting from the inclusion in
Employee's income of the gross up payments made under this Section. The amounts
payable to Employee hereunder shall be paid by Employer within five business
days after Employee submits a calculation of the amount due to him under this
Section, which statement may be an estimated statement based upon the
information available to Employee at the time the statement is submitted. If
payment is made by Employer based on such estimated payment, Employee shall
submit to Employer a final statement based upon the Employee's tax return as
filed for the year in question, which final statement shall be submitted not
later than 30 days after the date on which Employee files his federal income
tax return for such year. Such final statement shall contain a reconciliation
of to the estimated statement and payment of the amounts due to or from
Employee shall be paid within 3 days after the final statement has been
submitted.

                           splits or recapitalizations. If any adjustment under
                           this Section would create the right of Employee to
                           acquire a fractional share of stock, such fractional
                           share shall be disregarded and the number of shares
                           of common stock subject to the grant shall be the
                           next higher number of whole shares of common stock,
                           rounding all fractions upward.

                                    provided, however, that such repurchase
                                    shall only be required if it can be
                                    effected in a manner that complies with all

the Employee shall not be required to sell any of the Required Number of Shares
unless the net proceeds paid to the Employee as a result of such shares equals
or exceeds 150% of the IPO Price per share.

                  Nothing in this Section 4.2(ii) shall be construed to require

                  At such time as counsel for the Employee, which is acceptable
to Employer, which acceptance shall not be unreasonably withheld, opines that
the aforementioned stock restriction and legend can be removed from the
certificates representing stock granted pursuant to Section 4.1 (i) hereof in
accordance with applicable securities law, Employer agrees to delete
