Item 1.01. Entry into a Material Definitive Agreement.

Completion of Sale of Senior Notes due 2023

On November 9, 2015, Central Garden & Pet Company (the “Company”) completed the sale of $400 million aggregate principal amount of 6.125% Senior Notes due 2023 (the “2023 Senior Notes”). The Company sold the 2023 Senior Notes pursuant to an underwriting agreement, dated November 4, 2015 (the “Underwriting Agreement”), among the Company, the subsidiary guarantors party thereto (the “Subsidiary Guarantors”) and J.P. Morgan Securities LLC, as representative of the several underwriters named in the Underwriting Agreement. The Company intends to use the proceeds (net of fees and expenses incurred in connection with the offering) from the sale of the 2023 Senior Notes to redeem its outstanding 8.25% Senior Subordinated Notes due 2018.

The 2023 Senior Notes are governed by, and were issued pursuant to, the Indenture dated as of March 8, 2010 by and between the Company and Wells Fargo Bank, National Association, as trustee (the “Trustee”) (the “Base Indenture”), as supplemented by that Third Supplemental Indenture dated as of November 9, 2015 by and among the Company, the guarantors named therein and the Trustee (the “Third Supplemental Indenture” and together with the Base Indenture, the “Indenture”). The Indenture provides, among other things, that the 2023 Senior Notes will bear interest at a rate of 6.125% per annum, payable on May 15 and November 15 of each year, commencing May 15, 2016. The 2023 Senior Notes mature on November 15, 2023. The 2023 Senior Notes and the Indenture contain customary covenants and events of default, including failure to pay principal or interest on the 2023 Senior Notes when due, among others.

The 2023 Senior Notes are unsecured obligations of the Company and rank equal in right of payment with the Company’s existing and future unsecured senior debt. The Company’s obligations under the 2023 Senior Notes are fully and unconditionally guaranteed by the Subsidiary Guarantors (the “Guarantees”). The Guarantees are unsecured general obligations of the Subsidiary Guarantors and rank equal in right of payment with all existing and future unsecured liabilities of the Subsidiary Guarantors that are not subordinated in right of payment to the Guarantees.

The foregoing description is qualified in its entirety by reference to the full text of the Underwriting Agreement, the Third Supplemental Indenture (which includes the form of the 2023 Senior Notes and the Guarantees).

The information regarding the sale of the 2023 Senior Notes set forth in Item 1.01 above is incorporated herein by reference.
