The Company and the Rights Agent have executed and entered into that certain Stockholder Rights Agreement, dated as of December 5, 2008 (the “Rights Agreement”). Pursuant to Section 5.4 of the Rights Agreement, the Company and the Rights Agent may from time to time supplement or amend the Rights Agreement in accordance with the provisions of Section 5.4 thereof and the Company desires and directs the Rights Agent to so amend the Rights Agreement.

In consideration of the foregoing premises and mutual agreements set forth in the Rights Agreement and this Amendment, the parties hereto agree as follows:

1. Section 1.1 of the Rights Agreement, which sets forth the definition of “Acquiring Person,” is hereby modified and amended to read in its entirety as follows:

“Acquiring Person” shall mean any Person who is or becomes the Beneficial Owner of 20% or more of the outstanding shares of Common Stock; provided, however, that the term “Acquiring Person” shall not include (a) the Company; (b) any Subsidiary of the Company; (c) any employee stock ownership or other employee benefit plan of the Company or a Subsidiary of the Company (or any entity or trustee holding shares of Common Stock for or pursuant to the terms of any such plan or for the purpose of funding any such plan or funding other employee benefits for employees of the Company or of any Subsidiary of the Company); (d) any Person (i) who is the Beneficial Owner of 20% or more of the outstanding shares of Common Stock on the date of this Agreement and who has continuously been, since the date of this Agreement the Beneficial Owner of 20% or more of the outstanding shares of Common Stock until such time hereafter as such Person shall become the Beneficial Owner (other than by means of a stock dividend, stock split or reclassification or pursuant to an award granted by the Company under any equity-based compensation plan) of an additional one percent (1%) or more of the then-outstanding shares of Common Stock, unless, upon becoming the Beneficial Owner of such additional one percent (1%) or more of shares of Common Stock, such Person is not then the Beneficial Owner of 20% or more (which calculation shall include the additional shares acquired) of the then outstanding shares of Common Stock, (ii) who becomes the Beneficial Owner of 20% or more of the outstanding shares of Common Stock solely as a result of an acquisition by the Company of shares of Common Stock until such time thereafter as such Person shall become the Beneficial Owner (other than by means of a stock dividend, stock split or reclassification) of one or more additional shares of Common Stock while such Person is or as a result of which such Person becomes the Beneficial Owner of 20% or more of the outstanding shares of Common Stock, (iii) who becomes the Beneficial Owner of 20% or more of the outstanding shares of Common Stock but who (in the good faith determination of the Board of
