On November 4, 2016, Lazard Group LLC (“Lazard Group”), a subsidiary of Lazard Ltd, completed its previously announced offering of an aggregate principal amount of $300 million of Lazard Group’s 3.625% Senior Notes due 2027 (the “Notes”) in a registered public offering pursuant to Lazard Group’s shelf registration statement on Form S-3, filed with the Securities and Exchange Commission on May 29, 2014 (Registration No. 333-196350).

The Notes were issued pursuant to a Seventh Supplemental Indenture, dated November 4, 2016 (the “Seventh Supplemental Indenture”), between Lazard Group and The Bank of New York Mellon, as trustee, to an Indenture, dated May 10, 2005 (the “Indenture”), between Lazard Group and The Bank of New York Mellon (formerly known as The Bank of New York), as trustee. The Notes bear interest at the rate of 3.625% per year. Interest on the Notes is payable on March 1 and September 1 of each year, beginning on March 1, 2017. The Notes will mature on March 1, 2027. Lazard Group may, at its option, redeem some or all of the Notes at any time by paying the applicable redemption prices set forth in the Indenture and the Seventh Supplemental Indenture. In addition, holders of the Notes may require Lazard Group to repurchase the Notes upon the occurrence of a change of control triggering event. The Notes are senior unsecured obligations of Lazard Group and rank equally with all of its other existing and future senior unsecured indebtedness. Neither Lazard Ltd nor any of Lazard Group’s subsidiaries will guarantee the Notes. The Indenture and Seventh Supplemental Indenture contain certain covenants, events of default and other customary provisions.

On November 1, 2016, Lazard Group entered into an underwriting agreement (the “Underwriting Agreement”) with Citigroup Global Markets Inc. and Goldman, Sachs & Co., as representatives of the several underwriters listed on Schedule I thereto (collectively, the “Underwriters”), pursuant to which Lazard Group agreed to sell and the Underwriters agreed to purchase, subject to and upon terms and conditions set forth therein, the Notes.

The foregoing descriptions of the Notes, the Indenture, the Seventh Supplemental Indenture and the Underwriting Agreement are only a summary and are qualified in their entirety by reference to the full text of the Indenture, the Seventh Supplemental Indenture and the Underwriting Agreement. A copy of the Seventh Supplemental Indenture is attached hereto as Exhibit 4.1, a copy of the Indenture is attached as Exhibit 4.1 to Lazard Group’s Registration Statement (File No. 333-126751) on Form S-4 filed on July 21, 2005, a copy of the Underwriting Agreement is attached hereto as Exhibit 1.1 and each is incorporated herein by reference.
