            The Reporting Persons acquired the shares of Common Stock reported
herein, and continue to hold such shares, for investment purposes, with no
intention to influence or change the management or other affairs of the Company.

            On November 22, 2002, the Company notified Mr. Sacane that the Board
of Directors may consider excluding the Reporting Persons from the definition of
"Acquiring Persons" under the Company's Rights Agreement, notwithstanding the
Reporting Persons ownership percentage in the Company, if certain of the
Reporting Persons make certain representations to the Board. A copy of such
representations is attached hereto as Exhibit 1.

            On November 26, 2002, the Company amended its Rights Agreement to
exclude the Reporting Persons from the definition of "Acquiring Persons",
subject to certain limitations.

            In July 2003, the Reporting Persons discovered that from November
22, 2002 through July 24 2003, they had inadvertently purchased additional
shares of the Company, as reported herein.

            On July 25, 2003, the Reporting Persons informed the Company that
the Reporting Persons had inadvertently acquired additional shares of the
Company.

            On July 29, 2003 (i) the Reporting Persons entered into an
agreeement with the Company in which the Reporting Persons agreed to certain
restrictions on their ability to transfer and vote shares of the Company and
(ii) the Company amended its Rights Agreement to exclude the Reporting Persons
from the definition of "Acquiring Persons," subject to certain limitations. A
copy of the July 29, 2003 agreement is attached as Exhibit 2.

            The Reporting Persons reserve the right to dispose of shares, in
their sole discretion, subject to the agreement and applicable securities laws
and market conditions.

            Except as otherwise indicated in this report, the Reporting Persons
currently have no plans or proposals that relate to any of the matters described
in subparagraphs (a) through (j) of Item 4 to Schedule 13D.

Item 5. Interest in Securities of the Issuer.

            (a) The aggregate percentage of the outstanding shares of Common
Stock reported owned by each Reporting Person is based upon 29,480,766 shares of
