        <footnote id="F1">This Statement is filed jointly by UBS Group AG for the benefit and
on behalf of UBS Securities LLC
a wholly owned subsidiary of UBS Group</footnote>
        <footnote id="F2">UBS Group AG UBS,involuntarily became a 10 percent beneficial owner
 of GLST shares through no affirmative act of UBS.
 More specifically, a corporate action
 undertaken outside of UBSs control
substantially reduced the issuers total
 shares outstanding, thereby increasing the beneficial ownership
 percentage of UBS s holding above the 10 percent threshold.
 While UBS temporarily was
 a 10 percent beneficial owner of GLST shares,
 all transactions executed by UBS were sales,
 resulting in no short swing profits.</footnote>
