Mr. Michael W. Towe

Dear Mike:

This letter agreement (“Agreement”) confirms the agreements and understandings between you and Roper Industries, Inc. (the “Company”) regarding (1) your separation from service with the Company, (2) the benefits to which you are entitled upon separation, and (3) the additional consideration the Company is offering to you in exchange for a complete release of any and all claims against the Company and any Affiliate, as set forth below.

Separation Date

The parties to this Agreement acknowledge that you have indicated your desire to pursue other interests and that the Company has agreed to your separation from service from the Company. To effect such separation, the parties have agreed that your employment with the Company will end on the terms and conditions described in this Agreement, including the release outlined below, and that the separation will be effective on the date first written above (hereafter the “Separation Date”), provided that the release described below will be effective from the date of your signature below if that date is later.

Separation Benefits

By accepting the terms of this Agreement, you will become entitled to receive the following compensation and benefits from the Company:

Health and Welfare Benefits – If you were participating in medical, dental, and/or vision coverage for yourself and any eligible dependents, all active coverage will end as of the Separation Date. You will receive a packet regarding continuation of benefits under COBRA (Consolidated Omnibus Benefits Reconciliation Act), and you and any eligible dependents may elect to continue coverage for up to an additional eighteen (18) months, provided you timely enroll for coverage. The Company will pay the cost of the first twelve (12) months of COBRA coverage for you. In addition, the Company will continue any other healthcare reimbursement benefit(s) for yourself in which you were participating on the Separation Date for the first (12) months following the Separation Date. All other health and welfare benefits end as of the Separation Date.

Initial Award of Restricted Stock – Because we have mutually agreed to your separation from the Company, the 15,000 restricted shares awarded to you at the time of hire (now 30,000, after giving effect to the recent stock split) will vest on the eighth day immediately following the Separation Date.

Options – The deadline to exercise any fully vested options that you hold on the Separation Date will be extended to sixty (60) days after the Separation Date.

Severance – You will receive severance pay at your current base salary level through December 31, 2006. You will also receive an additional severance payment of $15,000 within 15 days after the Separation Date.

Incentive – For the 2005 plan year, the Company agrees to waive the requirement of continued employment for incentive eligibility and agrees to pay to you a $100,000 incentive payment for the 2005 plan year, which will be paid to you within 15 days after the Separation Date.

Perquisites – All perquisites, such as your Executive Financial Planning Allowance and your Company car, terminate as of the Separation Date.

Return of company property – You may cooperate with the Company to arrange a convenient time and place to return the Company car or you must surrender it immediately if requested to do so by the Company. You must immediately return to the attention of Mr. David Liner, General Counsel, Roper Industries, Inc. 2160 Satellite Blvd, Suite 200, Duluth, GA 30097, all other Company property in your possession, including but not limited to computers, credit cards, documents and records of the Company or any Affiliate, in whatever medium and of whatever kind or type. As additional consideration for the release below, after the Company has had an opportunity to remove any Company data from the Company computer that is currently assigned to you, the Company will transfer ownership of that computer to you on an as-is, where-is basis. After the Separation Date you should no longer have files or documents containing confidential information of the Company in your possession, however, to the extent any such information remains in your possession or memory, you agree to continue to protect that information and refrain from using or disclosing that information.

Release

The Company’s decision to offer additional consideration in exchange for a release of claims shall not be construed as an admission by the Company of (i) any liability whatsoever, (ii) any violation of any of your rights or those of any person, or (iii) any violation of any order, law, statute, duty, or contract. The Company specifically disclaims any liability to you or to any other person for any alleged violation of any rights possessed by you or any other person, or for any alleged violation of any order, law, statute, duty, or contract on the part of the Company, its employees or agents or related companies or their employees or agents.

You acknowledge that the consideration being paid to you under the terms of this Agreement exceeds the amount, if any, to which you are otherwise entitled.

The release and discharge of claims contained herein applies to (i) Roper Industries, Inc., (ii) to each and all of its Affiliates¹, (iii) to each of their past, present, and future officers, agents, directors, supervisors, employees, representatives, and their successors and assigns, whether or not acting in the course and scope of employment, and (iv) to all persons acting by, through, under, or in concert with any of the foregoing persons or entities (all collectively the “Company” for purposes of this release).

The claims subject to this release include, without limitation, any and all claims related or in any manner incidental to your employment with the Company or the termination of that employment relationship.

All such claims (including related attorneys’ fees and costs) are forever barred by this Agreement, without regard to whether those claims are based on an alleged violation of any federal, state, municipal or other law, contract, or common-law duty; any alleged unlawful act; and any other claim or cause of action, regardless of the forum in which it might be brought and regardless of whether it is based upon domestic or foreign laws, including without limitation, the laws of the United States of America (and any jurisdiction within).
