Executive Incentive Compensation Plan (the “EICP”), the DPL Inc. 2006 Deferred Compensation Plan for Executives and the DPL Inc. Pension Restoration Plan (collectively, the “Plans”);

WHEREAS, Executive’s participation in the Plans and eligibility for the benefits provided thereunder requires execution of this Agreement; and

WHEREAS, DPL desires to provide Executive benefits in addition to those provided by the Program, as described herein.

NOW THEREFORE, in consideration of the promises and agreements contained herein and other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, and intending to be legally bound, Executive agrees as follows:

1.             Effective Date.    This Agreement is effective on the Effective Date and will continue in effect as provided herein.

2.             Participation in the Plans.    DPL confirms that Executive has been designated by the Committee and the Board to participate in each of the Plans pursuant to the terms thereof as of the date Executive commences his employment, contingent on his execution of this Agreement. Executive is eligible to receive additional benefits as such are provided to other similarly situated employees of the Company from time to time.

3.             Perquisite Allowance.    By executing this Agreement, Executive shall be entitled to receive a perquisite allowance in the amount of $20,000 per year (the “Perquisite Allowance”), for each year that (a) Executive remains designated by the Committee as eligible to receive the Perquisite Allowance and (b) DPL continues to make the Perquisite Allowance available to executive-level employees of the Company.
