        <footnote id="F1">The 6.5% Senior Convertible Notes are convertible by the holder at any time.</footnote>
        <footnote id="F2">These securities are held for the account of certain private investment funds for which Angelo, Gordon &amp; Co., L.P. (&quot;Angelo, Gordon&quot;) acts as investment adviser.  John M. Angelo is a managing member of JAMG LLC, which is the general partner of AG Partners, L.P., which is the sole general partner of Angelo, Gordon.

    <remarks>Remarks:

The Reporting Persons had a relationship with other security holders of the Issuer who, in the aggregate, may be deemed to beneficially own, as a result of their ownership of convertible debt securities of the Issuer, more than 10% of the Issuer's common stock as determined under Section 13(d) of the Securities Exchange Act of 1934. Each of the Reporting Persons disclaims membership in a &quot;group&quot; with those security holders as that term is used in Section 13(d) and denies that it, or any entity for which it serves as investment manager, is subject to Section 16 of the Securities Exchange Act of 1934 with respect to its ownership of or transactions in equity securities of the issuer. Each of the Reporting Persons is filing this Form 3 for informational purposes, and the filing of this Form 3 shall not be deemed an admission that the reporting person is a member of such a group or is otherwise subject to Section 16.

The filing of this statement shall not be deemed an admission that any of the Reporting Persons is the beneficial owner of any securities not held directly for its account for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or otherwise.
