Re:     Power Systems Sale Incentive Bonus

Joe,

As you know, Rockwell Automation, Inc. (“Rockwell Automation”) is considering
the sale of its Power Systems business (“Power Systems”). We believe Power
Systems has a strong future and you will have a key role in this process.

To encourage you to remain with Power Systems through the closing of the sale of
Power Systems (the “Closing Date”) and to provide you with an additional
incentive to continue to promote the best interests of Rockwell Automation and
Power Systems, we are offering you an Incentive Bonus, subject to the terms and
conditions described below.

I.     Incentive Bonus

        A.      Amount of Bonus.  The Incentive Bonus will range from $1 million
to $6 million based on the proceeds of the sale of Power Systems received by
Rockwell Automation, as determined in accordance with Exhibit A to this letter
agreement. Notwithstanding the above, the CEO of Rockwell Automation may in his
sole discretion adjust the amount of your Incentive Bonus downward by up to 50%,
based upon his evaluation of your efforts and support of this process.

        B.      Time and Form of Payment of Bonus.  Any Incentive Bonus will be
payable in a single lump sum, in cash, less all applicable tax withholdings and
deductions, promptly following the Closing Date (and in any event within 2 1/2
months following the year in which the Closing Date occurs).

        C.      Bonus Contingent Upon Closing of Sale.  Payment of any Incentive
Bonus is contingent upon the successful closing of the sale of Power Systems on
or before June 30, 2007. This means that you will not receive an Incentive Bonus
unless Power Systems is sold on or before June 30, 2007. If Rockwell Automation
decides not to sell Power Systems, the CEO of Rockwell Automation may, in his
sole discretion, recommend to the Compensation and Management Development
Committee that you receive payment of an Incentive Bonus in such amount as he
shall determine based upon his views of your contribution during the sale
process.

--------------------------------------------------------------------------------

        D.      Termination of Your Employment Before the Closing Date.  If
before the Closing Date (1) you voluntarily terminate your employment for any
reason, retire without mutual agreement or die, (2) your employment is
terminated in connection with your long-term disability, or (3) Rockwell
Automation terminates your employment for “cause”, you will not be entitled to
any Incentive Bonus. For purposes of this letter agreement, “cause” means (i)
your commission of an act of malfeasance, dishonesty, fraud, or breach of trust
against Rockwell Automation or Power Systems or any of its employees, clients,
or suppliers, (ii) your breach of any of your obligations under this letter
agreement, or any other agreement between you and Rockwell Automation or Power
Systems, (iii) your failure to comply with the written policies of Rockwell
Automation or Power Systems; (iv) your failure, neglect, or refusal to perform
your duties for Rockwell Automation or Power Systems, or to follow the lawful
written directions of Rockwell Automation or Power Systems, (v) your conviction
of, or plea of no contest to, any felony or any crime involving moral turpitude,
(vi) any act or omission by you which is, or is reasonably likely to be,
injurious to the financial condition or business reputation of Rockwell
Automation or Power Systems, or which otherwise is injurious to employees,
clients, or suppliers of Rockwell Automation or Power Systems, and (vii) your
inability, as a result of repeated alcohol or drug use, to perform the duties
and/or responsibilities of your position.

        E.      Impact on Other Bonuses and Benefits.  The Incentive Bonus will
be in addition to your FY2006 ICP bonus. This bonus will not be included for
pension, savings plan or deferred compensation purposes.

II.    Confidentiality

You agree to keep the terms and conditions of Exhibit A to this letter agreement
confidential. Any breach of that confidentiality will cause you to forfeit any
and all payments and benefits under this letter agreement.

III.   Other Important Information

        A.      Plan Interpretations.  Rockwell Automation has full and complete
authority, in its sole and absolute discretion, (i) to construe, interpret and
implement this letter agreement and any related document, including for example
eligibility for and entitlement to benefits, and (ii) to make all determinations
necessary or advisable in administering this letter agreement. The actions of
Rockwell Automation on all matters relating to this letter agreement will be
final, binding and conclusive on all parties.

        B.      Non-Assignability.  Except as otherwise determined by Rockwell
Automation, you may not assign or transfer this letter agreement or any payments
or benefits under this letter agreement.

--------------------------------------------------------------------------------

        C.      No Right to Continued Employment. Nothing contained in this
letter agreement gives you any right to continue in the employ or other service
of Rockwell Automation or Reliance Electric. This letter agreement does not
constitute any contract or limit in any way the right of Rockwell Automation or
Power Systems to change your compensation or other benefits or to terminate your
employment or other service with or without cause.

        D.      Counterparts.  This letter agreement may be executed in separate
counterparts, each such counterpart being deemed to be an original instrument,
and all such counterparts will together constitute the same agreement.

        E.      Governing Law.  This letter agreement and all actions taken
under this letter agreement will be governed by, and construed in accordance
with, the laws of the State of Delaware without regard to the conflict of law
principles thereof.

*    *    *

We believe that you are, and continue to be, a key player in the success of
Power Systems and will be instrumental in the successful completion of this
transaction. We hope that this arrangement provides you with a greater sense of
security and motivation to conclude this transaction and continue to drive the
growth and performance of Power Systems.

Regards,

ROCKWELL AUTOMATION, INC.
