FOURTH AMENDMENT TO THE
LANSING BOARD OF WATER AND LIGHT
EMPLOYEES' DEFINED CONTRIBUTION PENSION PLAN

The Lansing Board of Water and Light Employees' Defined Contribution Pension Plan is hereby amended effective March 28, 2005 by making the change noted below.

Section 6.3(c)(2) shall be replaced in its entirety with the following:

"If the value of a Participant' s vested interest in the Trust at the time of distribution does not exceed $1,000 or such other maximum amount as is permitted by relevant law, any benefit payable hereunder will be paid within one year after termination of employment in the form of a lump sum distribution (the "Involuntary Cash-out"). If a Participant would have received a distribution under the preceding sentence but for the fact that the Participant' s vested account balance exceeded $1,000 when the Participant terminated service and if at a later time such account balance is reduced such that it is not greater than $1,000, the Participant will receive a distribution of such account balance and the nonvested portion will be treated as a Forfeiture. For purposes of this paragraph, if the value of a Participant' s combined vested account balances is zero, the Participant shall be deemed to have received a distribution of such vested account balances.  Any portion of his or her Employer Basic Contribution Account which is not vested on the date of the Involuntary Cash-out shall be forfeited in accordance with Section 4.3."
