         (c) On November 15, 2005, CV Starr entered into a variable pre-paid
forward sale contract (the "CSFB Contract") for up to 4,423,116 shares (the
"CSFB Maximum Number") of Common Stock pursuant to a letter agreement by and
among CV Starr, Credit Suisse First Boston LLC and Credit Suisse First Boston
Capital LLC ("CSFB"). The final terms of the CSFB Contract, including the CSFB
Maximum Number of shares deliverable by CV Starr upon settlement, were
determined in a block transaction between CV Starr and CSFB (or its affiliate),
acting as a block positioner, in accordance with the Securities and Exchange
Commission's interpretative letter to Goldman, Sachs & Co., dated December 20,
1999 (the "No Action Letter"). CV Starr has received aggregate proceeds of
$240,000,043 under the CSFB Contract.

         The CSFB Contract provides that for each of the 10 Scheduled Trading
Days (as defined in the CSFB Contract) prior to and including November 20, 2008
(the "CSFB Settlement Dates"), CV Starr will deliver a number of shares of
Common Stock to CSFB (or, at the election of CV Starr, the cash equivalent of
such shares) determined with respect to each CSFB Settlement Date as follows:
(a) if the VWAP Price (as defined in the CSFB Contract) per share of the Common
Stock (the "CSFB Settlement Price") is less than or equal to $65.85 (the "CSFB
Forward Floor Price"), a delivery of 1/10 of the CSFB Maximum Number of shares
of Common Stock, subject to rounding; (b) if the CSFB Settlement Price is
greater than the CSFB Forward Floor Price but less than or equal to $85.61 per
share (the "CSFB Forward Cap Price"), a delivery of shares equal to the CSFB
Forward Floor Price/CSFB Settlement Price x 1/10 of the CSFB Maximum Number of
shares of Common Stock, subject to rounding; and (c) if the CSFB Settlement
Price is greater than the CSFB Forward Cap Price, a delivery of shares equal to
((CSFB Forward Floor Price + (CSFB Settlement Price - CSFB Forward Cap Price)) /
CSFB Settlement Price) x 1/10 of the CSFB Maximum Number of shares of Common
Stock, subject to rounding.

         On November 21, 2005, CV Starr entered into a variable pre-paid forward
sale contract (the "Confirmation") for up to 2,917,916 shares (the "Citi Maximum
Number") of Common Stock pursuant to


                                       16



the Master Terms and Conditions for Pre-Paid Forward Contracts, dated as of
November 15, 2005 (together with the Confirmation, the "Citi Contract"), by and
between CV Starr and Citibank, N.A. ("Citibank"). The final terms of the Citi
Contract, including the Citi Maximum Number of shares that will be deliverable
by CV Starr upon settlement, were determined in unsolicited brokerage
transactions by Citibank (or its affiliate) over a specified execution period
beginning on November 18, 2005, in accordance with the No Action Letter. CV
Starr has received aggregate proceeds of $160,000,000 under the Citi Contract.

         The Citi Contract provides that for each of the 10 Scheduled Trading
Days (as defined in the Citi Contract) prior to and including December 10, 2008
(the "Citi Settlement Dates"), CV Starr will deliver a number of shares of
Common Stock to Citibank (or, at the election of CV Starr, the cash equivalent
of such shares) determined with respect to each Citi Settlement Date as follows:
(a) if the Relevant Price (as defined in the Citi Contract) per share of the
Common Stock (the "Citi Settlement Price") is less than or equal to $66.8540
(the "Citi Forward Floor Price"), a delivery of 1/10 of the Citi Maximum Number
of shares of Common Stock, subject to rounding; (b) if the Citi Settlement Price
is greater than the Citi Forward Floor Price but less than or equal to $86.9102
per share (the "Citi Forward Cap Price"), a delivery of shares equal to the Citi
Forward Floor Price/Citi Settlement Price x 1/10 of the Citi Maximum Number of
shares of Common Stock, subject to rounding; and (c) if the Citi Settlement
Price is greater than the Citi Forward Cap Price, a delivery of shares equal to
((Citi Forward Floor Price + (Citi Settlement Price - Citi Forward Cap Price)) /
Citi Settlement Price) x 1/10 of the Citi Maximum Number of shares of Common
Stock, subject to rounding.

         The descriptions of the CSFB Contract and the Citi Contract are
qualified in their entirety by the text of such contracts, copies of which are
