Item 3.     Source and Amount of Funds and Other Consideration.

            The 6,729,452 shares of Common Stock reported herein as being
beneficially owned by the Reporting Persons were acquired at an aggregate
purchase price of approximately $307,151,226. Such shares are held by the
Reporting Persons in commingled margin accounts maintained at UBS Securities
LLC, which may extend margin credit to the Reporting Persons from time to time,
subject to applicable federal margin regulations, stock exchange rules and
credit policies. In such instances, the positions held in the margin account are
pledged as collateral security for the repayment of debit balances in the
account. The margin accounts bear interest at a rate based upon the broker's
call rate from time to time in effect. Since other securities are held in the
margin accounts, it is not possible to determine the amounts, if any, of margin
used to purchase the shares of Common Stock reported herein.
