holder of a $30,000,000 MassMutual Corporate Investors ("MMCI")
Senior Fixed Rate Convertible Note (the "Note") entered into
November 15, 2007 and due November 15, 2017. The dollar amount
of principal of the Note is convertible into an equivalent
dollar amount of MMCI's common shares based upon the average
price of MMCI's common shares for ten business days prior to
MassMutual's notice of conversion. The ten business day average
closing market price of MMCI's common shares for
=================== =================
CUSIP No. 576292106 13G PAGE 4 OF 6 PAGES
=================== =================
the ten-day period ended December 31, 2008 was $18.65 and as such
the Note would have converted into approximately 1,608,579
common shares if the Note had been converted as of December 31,
2008. Since the conversion rate is based on the market price of
MMCI's common shares, MassMutual's beneficial ownership may be
slightly greater than or less than 10% at the end of any given
month.
Total shares of common shares owned directly and indirectly:
1,608,579 (subject to change with market). Additionally,
Cornerstone Real Estate Advisers LLC and Babson Capital
Management LLC, wholly-owned indirect subsidiaries of MassMutual,
are the beneficial owners of 27,009 and 82,823 and common shares
of MMCI, respectively.
The filing of this statement shall not be construed as an
admission that MassMutual is for the purpose of Sections 13(d)
and 13(g) of the Securities Exchange Act of 1934, the beneficial
owner of any of the common shares stock of MMCI, including the
common shares held by Cornerstone Real Estate Advisers LLC or
Babson Capital Management LLC.
4(b) Percent of Class:
The 1,608,579 common shares mentioned above represent 14.72% of
MMCI's common shares calculated as follows:
1,608,579 (common shares from conversion based on a conversion
price of $18.65) / 1,608,579 (number of new common shares that
would be issued by MMCI upon conversion) + 9,319,,509 (common
shares outstanding as of December 31, 2008) = 14.72%
Since the conversion rate is based on the market price of
MMCI's common shares, MassMutual's beneficial ownership may
be slightly greater than or less than 10% at the end of any
given month.
4(c) Number of shares as to which such person has:
(i) sole power to vote or to direct the vote:
1,608,579 (subject to change with market)
(ii) shared power to vote or to direct the vote: 0
