List of Other Included Managers:
On January 1, 2000, Massachusetts Mutual Life Insurance Company
("MassMutual") transferred its investment management division and
its investment advisory business to its majority-owned, indirect
subsidiary, David L. Babson and Company, Inc. ("Babson").
Babson now has investment discretion over MassMutual's assets.
Please note that in the past Form 13F's were filed by
MassMutual on behalf of Babson and OppenheimerFunds Inc.
("Oppenheimer"). Babson and Oppenheimer are indirect,
majority-owned subsidiaries of MassMutual. For this filing,
and future filings, Babson and Oppenheimer will file Form 13F's
on their own behalf.
Babson and Oppenheimer have indicated that they exercise
"sole" investment discretion with respect to the
securities positions reported in their respective Form
13F's. Nevertheless, such positions shall also be deemed
reported on behalf of MassMutual to the extent that
MassMutual may be deemed to "share" investment
discretion over the positions as a result of its
ownership interests in Babson and Oppenheimer.
