Item 1.01 Entry into a Material Definitive Agreement.

As previously announced, on June 6, 2013, Stewart Enterprises, Inc. (the “Company”) commenced a consent solicitation to amend the indenture dated April 18, 2011 (the “Indenture”) governing its 6.50% Senior Notes due 2019 (the “Senior Notes”) on the terms and subject to the conditions set forth in the Company’s Consent Solicitation Statement, which it amended on June 10, 2013. On June 12, 2013, the Company announced that, as of 5:00 p.m., New York City time, on June 12, 2013, it had received the requisite consents to amend the Indenture and accordingly entered into a supplemental indenture, dated June 12, 2013 (the “Supplemental Indenture”), to the Indenture with U.S. Bank National Association, as trustee for the Senior Notes.

The Supplemental Indenture, among other things, waives the requirement under the Indenture to make a change of control offer to repurchase the Senior Notes in connection with the previously announced proposed acquisition of the Company by Service Corporation International and amends the Company’s reporting obligations under the Indenture.

A copy of the Supplemental Indenture is filed as Exhibit 4.1 hereto and is incorporated herein by reference. The description of the Supplemental Indenture contained herein is qualified in its entirety by the full text of such exhibit.

Item 3.03 Material Modification to Rights of Security Holders.

See Item 1.01 hereto, which is incorporated herein by reference, with respect to the execution of the Supplemental Indenture on June 12, 2013.

Item 8.01 Other Events.

On June 12, 2013, the Company issued a press release announcing that, as of 5:00 p.m., New York City time, on June 12, 2013, it had received the requisite consents to amend the Indenture governing its 6.50% Senior Notes due 2019 and entered into a Supplemental Indenture dated June 12, 2013, as discussed in Item 1.01 hereto. A copy of the press release is filed as Exhibit 99.1 hereto and incorporated herein by reference.
