Article 1 Effective Date

These additional clauses apply effective with the spinoff of WABCO, expected to be July 31, 2007 (the

Article 2 Function

The
parties have mutually agreed to change the function entrusted to the Employee under article 1 of the Employment Contract of March 1, 2003. Effective April 1, 2005, The Employee is entrusted with, and agrees to take on, the function of
Chief Financial OfficerWABCO.

Article 3 Compensation

As from the Effective Date, the Employees monthly salary, fixed at USD 15,915 under article 5, sub-article 1, paragraph 1, of the Employment Contract of March 1, 2003, as amended, is increased to USD
29,166.67.

The Employee shall be eligible for participation in the WABCO Annual Incentive Plan (AIP) with an annual incentive target of 40% of base
salary. The Employee shall participate in the WABCO Long Term Incentive Plan (LTIP) with a target of 40% of base salary. The actual amount payable to you as an annual or long-term incentive will be dependent upon the achievement of performance
objectives established in accordance with the terms of such annual or long-term incentive plan. Accordingly, depending on such performance, the actual amount payable to you in respect of such opportunities (including any equity compensation awards
provided in respect of your employment) may provide you with actual compensation that is less than, greater than or equal to the target opportunities or other values specified above. Any incentive compensation award will be in such form or forms,
and subject to such terms and conditions, as shall be determined by the committee responsible for the administration of the applicable plan, policy or program.

such award will be in the form of restricted stock units, which represent the right to receive, subject to the terms and conditions of such award, a corresponding number of shares of WABCOs Common Stock, and the other half will be in
non-qualified stock options. The value of, and the number of shares subject to, each such award shall be determined in a manner consistent with the generally applicable grant practices as applied by Parent prior to the date hereof (that is, the
value and size of each restricted stock unit grant will be determined based on the fair market value of a share of the WABCO common stock on the grant date (the Grant Date Value)and of each stock option grant will be determined
based on the Black-Scholes value of a stock option in respect of one share of the Common Stock, as determined based on the Grant Date Value of such Common Stock).

Attachment A

Definitions

Causemeans (i) your willful and continued failure substantially to
perform your duties (other than any such failure resulting from incapacity due to reasonably documented physical or mental illness), after a demand for substantial performance is delivered to you, which specifically identifies the manner in which it
is believed that you have not substantially performed your duties, (ii) conviction of, or plea of nolo contendere to, a felony, or (iii) the willful engaging by you in gross misconduct that is materially and demonstrably injurious to
Employer and/or its affiliated companies (the Company Group)or materially impairs your trustworthiness or effectiveness in the performance of your duties. For purposes hereof, no act, or failure to act, on your part shall
be considered willful unless done, or omitted to be done, by you not in good faith and without reasonable belief that your action or omission was in the best interest of WSW and its affiliated companies. Any act, or failure to act, based
upon authority given pursuant to a resolution duly adopted by the Board of Directors of WABCO Holdings Inc. or based upon the advice of counsel for Employer or any of its affiliated companies shall be conclusively presumed to be done, or omitted to
be done, by you in good faith and in the best interest of the Company Group.

Good Reasonmeans any of the following:

(i) a material diminution in your authority, duties, responsibilities status or position(s) as an executive of the Company Group;

(ii) a relocation of your principal offices by at least 30 miles from your initial location under this assignment (other than in connection with repatriation);

(iii) a reduction by the Company Group in your base salary;

(iv) the taking of any action by the Company Group (including the elimination of a plan without providing substitutes therefor or the reduction of your awards thereunder) that would substantially diminish the aggregate projected value of
your awards under the Company Groups applicable incentive plans in which you were participating at the time of the taking of such action;

---

(v) the taking of any action by the Company Group that would substantially diminish the aggregate value of the benefits
provided you under the Company Groups applicable medical, health, accident, disability, life insurance, thrift and retirement plans in which you were participating at the time of the taking of such action; or

(vi) any purported termination by the Company Group of your employment that is not effected for Cause, provided that this shall not include any termination of employment
pursuant to the Company Groups applicable mandatory retirement policy for executive officers.

Notwithstanding the foregoing, a termination for Good
Reason shall not have occurred (a) with regard to the occurrence of the events described in subsections (iii), (iv) and (v) above prior to a Change of Control, if such reductions or actions are proportionate to the reductions or
actions applicable to similarly situated executive officers of the Company Group pursuant to a cost savings plan or (b) unless you give the Company written notice that such event constitutes Good Reason within 90 days of first having knowledge
of such event and the Company fails to cure the event within 30 days after receipt of such written notice.
