Second Amendment to Restructuring Support Agreement

On October 20, 2016, Stone Energy Corporation (“Stone”) and certain of its subsidiaries (collectively, the “Company”) entered into a restructuring support agreement, as amended on November 4, 2016 (the “RSA”), with certain (i) holders of the Company’s 1 ³⁄₄% Senior Convertible Notes due 2017 (the “Convertible Notes”) and (ii) holders of the Company’s 7 ¹⁄₂% Senior Notes due 2022 (together with the Convertible Notes, the “Notes” and the holders thereof, the “Noteholders”), to support a restructuring on the terms of a pre-packaged plan of reorganization as described therein (the “Plan”). On November 9, 2016 the Company and the Noteholders entered into a second amendment to the RSA (the “Second RSA Amendment”) that extends the requirement to commence solicitation to approve the Plan from November 10, 2016 to November 15, 2016.

The foregoing description of the Second RSA Amendment is qualified by reference to the full text of such amendment, a copy of which is filed herewith as Exhibit 10.1 and is incorporated herein by reference.

Although the Company intends to pursue the restructuring in accordance with the terms set forth in the RSA, as amended by the Second RSA Amendment, there can be no assurance that the Company will be successful in completing a restructuring or any other similar transaction on the terms set forth in the RSA and the Second RSA Amendment, on different terms or at all.

The information contained in the Second RSA Amendment and this Form 8-K are for informational purposes only and do not constitute an offer to buy, nor a solicitation of an offer to sell, any securities of the Company, nor do they constitute a solicitation of consent from any persons with respect to the transactions contemplated hereby and thereby. While we expect the restructuring will take place in accordance with the Plan, there can be no assurance that the Company will be successful in completing a restructuring. Securityholders are urged to read the disclosure materials, including the disclosure statement, if and when they become available because they will contain important information regarding the restructuring.

(d) Exhibits.
