Footnotes (1)

[F1]Pursuant to an Agreement and Plan of Merger, dated November 20, 2011 (the "Merger Agreement"), by and among the Transatlantic Holdings, Inc. ("TRH"), Alleghany Corporation ("Alleghany") and Shoreline Merger Sub, Inc. (formerly, Shoreline Merger Sub, LLC) ("Merger Sub"), TRH merged with and into Merger Sub, with Merger Sub surviving as a wholly-owned subsidiary of Alleghany (the "Surviving Company"). At the Effective Time (as defined in the Merger Agreement), the Restricted Stock Units ("RSU's") were converted into the right to receive cash in an amount equal to the Per Share Amount (as defined in the Merger Agreement) multiplied by the number of outstanding RSU's held by the reporting person, with such cash amount converted into a number of phantom units of the Surviving Company determined by dividing such cash amount by the fully diluted book value per share of the Surviving Company.
