Any ballot marked  'Abstain' is considered  to have been voted.  Ballots  marked
'Abstain'  are   considered   to  be  have  been  voted   against   management's
recommendation,  regardless of whether the recommendation is 'For' or 'Against,'
except where  management  has made no  recommendation  or has  recommended  that
shareholders 'Abstain.'

Where  management has recommended that  shareholders  'Abstain' from voting on a
ballot item: 1) a ballot  market  'Abstain' is considered to have been voted for
management's  recommendation  to  'Abstain'  and  2) a  ballot  voted  'For"  or
'Against' is considered to have been voted against  management's  recommendation
to 'Abstain.'

Where management has made no  recommendation  on a ballot item, the abbreviation
"N/A" is used to denote that there is no applicable  recommendation  compared to
which a vote may be 'For' or 'Against' the recommendation of management.
