MNTA Major Shareholders

[Updated for addition by BlackRock in Form 13G filed 1/10/14.]


The table below shows the shareholdings of all MNTA shareholders
who filed SEC Form 13G during the past 12 months; the table
entries are not updated from quarterly filings on Form 13F-HR,
and hence they may not coincide precisely with the amounts shown
on Form 13F-HR; however, the figures in the table below should be
close enough for investment purposes.

The percentages in the table are based on 54.3M diluted shares
(#msg-76922372) and do not concur with the percentages on
SEC Form 13G, which uses a different formula.
