COMMON STOCK</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our common stock is listed on the New York Stock Exchange under the trading symbol &#147;WMI.&#148; On
July&nbsp;26, 2007, the last reported sale price of the common stock on the New York Stock Exchange was
$37.81 per share.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are issuing the shares directly to a warrant holder upon exercise by such holder of an
outstanding warrant. The warrant, originally issued in 1997, entitles the holder to purchase an
aggregate of 15,000 shares of our common stock at a purchase price of $34.8750 per share. The
warrant contains a net settlement feature that allows the warrant holder to elect to pay the
exercise price of the warrant by having the Company withhold that number of shares that is equal to
the exercise price, based on a twenty day trailing average closing price of our common stock. The
warrant holder has elected this payment option and as a result, we are withholding 13,293 shares in
settlement of the exercise price and will not be receiving any cash proceeds.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>Investing in the common stock involves risks that are described in the &#147;Risk Factors&#148; section
of our periodic reports and incorporated in the prospectus dated September&nbsp;22, 2006 by reference to
the those reports.</B>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES COMMISSION HAS
APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE ADEQUACY OR ACCURACY OF THIS
PROSPECTUS SUPPLEMENT. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.</B>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>We expect to deliver the shares against payment therefor in Houston, Texas on or about July
27, 2007.</B>
