Exhibit 4.4

AMENDMENT NO. 2 TO RIGHTS AGREEMENT

“Acquiring Person” shall mean any Person who is Beneficial Owner (as hereinafter defined) of 15% or more of the outstanding shares of Voting Stock (as hereinafter defined); provided, however, that the term “Acquiring Person” shall not include (i) any Person who is the Beneficial Owner of 15% or more of the outstanding shares of Common Stock on the date of this Agreement or who shall become the Beneficial Owner of 15% or more of the outstanding shares of Voting Stock solely as a result of an acquisition by the Company of shares of Voting Stock, until such time hereafter or thereafter as any of such Persons shall become the Beneficial Owner (other than by means of a stock dividend or stock split) of any additional shares of Voting Stock, (ii) any Person who Beneficially Owns shares of Voting Stock consisting solely of one or more of (A) shares of Voting Stock Beneficially Owned pursuant to the grant or exercise of an option granted to such Person by the Company in connection with an agreement to merge with, or acquire, the Company at a time at which there is no Acquiring Person, (B) shares of Voting Stock (or securities convertible into, exchangeable into or exercisable for Voting Stock), Beneficially Owned by such Person or its Affiliates (as hereinafter defined) or Associates (as hereinafter defined) at the time of grant of such option or (C) shares of Voting Stock (or securities convertible into, exchangeable into or exercisable for Voting Stock) acquired by Affiliates or Associates of such Person after the time of such grant, which, in the aggregate, amount to less than 1% of the outstanding shares of Voting Stock, (iii) the Company, any wholly owned Subsidiary (as hereinafter defined) of the Company, and any employee stock ownership or other

employee benefit plan of the Company or a wholly owned Subsidiary of the Company, or (iv) Franklin Resources, Inc., until such time as Franklin Resources, Inc. becomes the Beneficial Owner (other than by means of a stock dividend or stock split) of more than 5,450,000 shares of Voting Stock (such number to be appropriately adjusted in the event of any stock dividend or stock split), provided that this clause (iv) shall have no effect (A) from and after such time as Franklin Resources, Inc. becomes the Beneficial Owner of less than 3,817,500 shares of Voting Stock or (B) from and after such time as Franklin Resources, Inc. (or any of its Affiliates) reports or is required to report its Beneficial Ownership of Voting Stock on Schedule 13D under the Securities Exchange Act of 1934 (or any comparable or successor report). Notwithstanding the foregoing, if the Board of Directors of the Company determines in good faith that a Person who would otherwise be an “Acquiring Person,” as defined pursuant to the foregoing provisions of this definition of “Acquiring Person,” has become such inadvertently, and such Person divests as promptly as practicable a sufficient number of shares of Common Stock so that such Person would no longer be an “Acquiring Person,” as defined pursuant to such foregoing provisions of this definition of “Acquiring Person,” then such Person shall not be deemed to be an “Acquiring Person” for any purposes of this Agreement.”

The Rights Agent will duly execute and deliver any supplement or amendment hereto requested by the Company which satisfies the terms of the preceding sentence. Any supplement or amendment satisfying the terms of the first sentence of this Section 5.4 shall be effective upon execution by the Company (whether or not then executed by the Rights Agent).”
