“Without limiting the foregoing, to the extent required by Section 414(u)(12) of the Code, if the Employer makes a “differential wage payment” within the meaning of Code Section 414(u)(12)(D) to a Participant on qualifying military leave, the Participant will be considered actively employed by the Employer during the period for which such payments are made and the payments shall be considered compensation for all purposes of the Plan. Additionally, in the case of a Participant who dies while performing “qualified military service” as defined in Section 414(u) of the Code, the Beneficiaries of the Participant shall be entitled to any additional vesting and other benefits the Participant would have received had the Participant resumed and then terminated employment on account of death.”

2.    Section (d) of Article IV E 2 and Section (f) of Article IV E 3 are hereby eliminated effective January 1, 2008.
