ITEM 1.01.  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On December 19, 2005, the Company agreed to amend the terms of outstanding
nonqualified stock options held by each of Anthony (Cob) W.P. Stenham, its
Chairman; Eric J. Tveter, its President and Chief Operating Officer;
Stephen S. Cook, its Vice President, Group Strategy Director and General
Counsel; and Neil R. Smith, its Vice President and Chief Financial Officer.
Each of these individuals holds options to purchase shares of common stock
of the Company with an exercise price of $0.01 per share. The amendment
provides that, as to any portion of the options that vests in 2005, the
holder will exercise that portion of the option on or before March 15,
2006. The amendment to these options provides further that, as to any
portion of the options that vests in 2006 or in a later calendar year, the
holder will exercise that portion of the option on the day of vesting. In
order to facilitate these exercises, the Company will, at the holder's
request, deduct from the number of shares to be issued upon any such
exercise a number of shares of common stock with a fair market value equal
to the taxes required to be withheld by reason of the exercise. The purpose
of these amendments is to cause the options so amended to comply with
Section 409A of the U.S. Internal Revenue Code of 1986, as amended. The
terms and conditions of the amendment of the applicable options are
evidenced by the form of Amendment to Nonqualified Stock Option Agreement
attached as Exhibit 10.1 to this Current Report on Form 8-K and
incorporated herein by reference.
