In all other cases, unless the Committee shall otherwise expressly provide in the agreement relating to an Award under the Plan, in the event of a Potential Change of Control, the Committee shall determine whether a Performance Goal has been achieved as of the last day of the prior quarter, and if such achievement equals or exceeds 50% of the Performance Goal corresponding to the threshold award level, then, in the event of a Change of Control, the Participant shall be entitled to receive a portion of his Award as follows: if a Participant has received all or any portion of his Award for a Performance Period prior to a Change of Control, no further Awards shall be payable to such Participant under this Plan following such Change of Control, and if a Participant has not received any portion of his Award for a Performance Period prior to a Change of Control, the Company shall distribute, within sixty days following such Change of Control, a pro-rata Award to such Participant based on his Target Award, provided the Participant is actively employed by the Company immediately prior to such Change of Control, and no further Awards shall be payable to such Participant under this Plan.

For purposes of this Section 10(d), a “Potential Change of Control” shall exist during any period in which the following items exist: (i) the Company enters into an agreement, the consummation of which would result in the occurrence of a Change of Control; (ii) any person (including the

Company) publicly announces an intention to take or to consider taking actions which if consummated would constitute a Change of Control; or (iii) the Board adopts a resolution to the effect that, for purposes of the Plan, a potential change of control exists.”

14. By substituting the following for the first sentence of Section 11 of the LTIP:

“The Plan shall be effective as of the Effective Date, with the last Performance Period under the Plan to begin January 1, 2011.”

15. By substituting the phrase “Section 9 or 10” for the phrase “Section 9” where it appears in Section 14 of the LTIP.
