Item 1.01 Entry into a Material Definitive Agreement

On December 14, 2007, Critical Path, Inc. (the “Company”) and Computershare Trust Company, N.A., as successor to Computershare Trust Company, Inc. (“Computershare”), entered into an amendment (“Amendment No. 9”) to the Preferred Stock Rights Agreement, dated as of March 19, 2001, between the Company and Computershare, as Rights Agent, as amended by Amendment No. 1, dated as of November 6, 2001, Amendment No. 2, dated as of November 18, 2003, Amendment No. 3, dated as of January 16, 2004, Amendment No. 4, dated as of March 9, 2004, Amendment No. 5, dated as of June 24, 2004, Amendment No. 6, dated as of December 29, 2004, Amendment No. 7, dated as of February 10, 2005, and Amendment No. 8, dated as of October 26, 2007 (collectively, the “Rights Agreement”). Capitalized terms not defined herein have the meaning set forth in the Rights Agreement.

Among other things, Amendment No. 9 amends the definition of “Beneficial Ownership” under the Rights Agreement to provide that no person that Beneficially Owns any securities of Parent or Merger Sub (a “Parent/Merger Sub Shareholder”) shall be deemed as a result of the Merger Agreement to Beneficially Own any securities of the Company. The amendment also provides that no person who enters into a voting agreement with any Parent/Merger Sub Shareholder in connection with the Merger Agreement shall be deemed, as a result of being a party to such voting agreement, to Beneficially Own any securities of the Company. The amendment further provides, for the avoidance of doubt, that the Merger Agreement, as well as the transactions, agreements, arrangements, actions, understandings or relationships contemplated by the Merger Agreement, are to be disregarded in the determination of (i) whether a person is an “Acquiring Person,” (ii) whether a person Beneficially Owns any of the Company’s securities and (iii) whether a “Triggering Event” has taken place.

The foregoing description of the terms of Amendment No. 9 is qualified in its entirety by reference to the copy of Amendment No. 9, filed with this report as Exhibit 4.10, incorporated herein by reference.
