Item 4. Ownership.

      On October 7, 2005, AMI and the Issuer entered into a Subscription
Agreement ("Subscription Agreement") which provides that AMI would purchase the
lesser of 10,703,704 shares of Common Stock or that number of shares of Common
Stock that has an aggregate purchase price under the Subscription Agreement
equal to $34,000,000.00. The shares were to be purchased over a period of ten
business days. The purchase price of each share purchased on any of the days was
to be set at 96% of the volume weighted average price of the Issuer's Common
Stock on that day, as quoted by Bloomberg, LP; provided however, that if the
Issuer offered Common Stock to one or more third parties at a price lower than
that amount, the purchase price would be the lowest price at which the Issuer
offers such shares of Common Stock.

      The Subscription Agreement contains provisions prohibiting AMI from
purchasing shares of common stock under the agreement if doing so would result
in the Reporting Persons and their affiliates beneficially owning shares
purchased under the Subscription Agreement that represent more than 9.99% of the
outstanding shares of Common Stock as determined under Section 13(d) of the
Securities Exchange Act of 1934.

      As of October 7, 2005, none of the Reporting Persons had record ownership
of any securities of the Issuer.
