The Reporting Persons originally acquired the Shares for investment in
the ordinary course of business because they believed that the Shares, when

opportunity.
The Reporting Persons originally filed a Schedule 13G with respect to
the Shares on February 10, 2006.
CUSIP No. 629519109 13G Page 8 of 9 Pages
On May 2, 2006, the Reporting Persons filed a Schedule 13D with
respect to the Shares, stating that the Reporting Persons were concerned that
the Issuer's management and board of directors would not maximize the Issuer's
value. The Reporting Persons did not attend the Issuer's 2006 annual meeting of
stockholders and encouraged certain other of the Issuer's shareholders to take
similar actions in an effort to deny the presence of a quorum and force the
Issuer to reschedule the Annual Meeting.
At this time, the Reporting Persons believe that the Issuer, its
management and Board of Directors have embarked on a good faith effort to
explore strategic alternatives and are satisfied that further action by the
Reporting Persons seeking to change or influence the control of the Issuer is
not necessary.
