purchase from the Company of an additional 453,001 shares

453,001 shares of Common Stock.  The purpose of this most
recent acqusition of shares of Common Stock is for
investment; the acquisition was made in the ordinary
course of Grace's business and was not made for the purpose
of acquiring control of the Company.

The Filers have no plans or proposals which relate to, or

Paragraphs (a) through (j), inclusive, of Item 4 of the
