ITEM 1.01   ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         On December 21, 2006, MetLife, Inc., a Delaware corporation
("MetLife"), completed a public offering of $1,250,000,000 aggregate principal
amount of its 6.40% Fixed-to-Floating Rate Junior Subordinated Debentures due
2066 (the "junior subordinated debentures"). The terms of the junior
subordinated debentures are set forth in an Indenture, dated as of June 21, 2005
(attached as Exhibit 4.5 to MetLife's Current Report on Form 8-K dated June 22,
2005 and incorporated herein by reference), as supplemented by the Third
Supplemental Indenture, dated as of December 21, 2006 (attached hereto as
Exhibit 4.1 and incorporated herein by reference), each between MetLife and The
Bank of New York Trust Company, N.A., as trustee (in the case of the Base
Indenture, as successor to J.P. Morgan Trust Company, National Association).

         The junior subordinated debentures were issued pursuant to an
underwriting agreement (the "Underwriting Agreement") and a pricing agreement
(the "Pricing Agreement"), each dated as of December 14, 2006, among MetLife and
Goldman, Sachs & Co., J.P. Morgan Securities Inc., Merrill Lynch & Co., and HSBC
Securities (USA) Inc., as representatives of the several underwriters named in
Schedule I to the Pricing Agreement (the "Underwriters"). Pursuant to the
Underwriting Agreement and Pricing Agreement (attached as Exhibits 1.1 and 1.2,
respectively, to MetLife's Current Report on Form 8-K dated December 20, 2006
and incorporated herein by reference), and subject to the terms and conditions
expressed therein, MetLife agreed to sell the junior subordinated debentures to
the Underwriters, and the Underwriters agreed to purchase the junior
subordinated debentures for resale to the public.

         On December 21, 2006, in connection with the completion of the
offering of the junior subordinated debentures, MetLife entered into a
replacement capital covenant (the "Replacement Capital Covenant") (attached
hereto as Exhibit 4.2 and incorporated herein by reference), whereby MetLife
agreed for the benefit of holders of a series of MetLife's long-term
indebtedness designated by MetLife in accordance with the terms of the
Replacement Capital Covenant from time to time ranking senior to the junior
subordinated debentures that the junior subordinated debentures will not be
repaid, redeemed or purchased by MetLife, on or before December 15, 2056,
unless such repayment, redemption or purchase is made from the proceeds of the
issuance of certain replacement capital securities and pursuant to the other
terms and conditions set forth in the Replacement Capital Covenant.

         The junior subordinated debentures were offered and sold by MetLife
pursuant to its registration statement on Form S-3 (File No. 333-124358).
