CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER PI LLC and PI CI LLC each also entered into a "collar" participation arrangement (the "Collar Agreement") through Bear Stearns International Limited ("Bear Stearns") pursuant to which both PI LLC and PI CI LLC agreed to purchase shares of Common Stock (the "Collar Shares") under certain circumstances from a trust established to receive payments on behalf of asbestos personal injury claimants (the "Asbestos Trust"). The Collar Agreement is a participation of Bear Stearn's current obligations under the Collar Agreement. From PI LLC's perspective, the collar transactions involve (i) a short put option which would have obligated PI LLC, at the request of the Asbestos Trust, to purchase from the Asbestos Trust 1,661,611 shares of Common Stock until April 9, 2007 at $25.00 per share, and (ii) a long call option providing PI LLC with the right to purchase 1,661,611 shares of Common Stock until January 8, 2008 at $37.50 per share.
