On February 13, 2012, Central Garden & Pet Company (the “Company”) entered into a supplemental indenture (the “Supplemental Indenture”) with certain subsidiaries of the Company that are guarantors and Wells Fargo Bank, National Association, as trustee, in connection with the Company’s offering of $50 million of its 8.25% senior subordinated notes due 2018 (the “Notes”) in a private placement. The Notes are part of a series of notes issued by the Company on March 8, 2010 and are substantially identical to the previously issued notes, except for the issue date, issue price, first interest payment date and transfer restrictions. A copy of the Supplemental Indenture is filed as Exhibit 4.1 hereto.

In connection with the offering of the Notes, the Company has agreed pursuant to a Registration Rights Agreement, dated as of February 13, 2012 (the “Registration Rights Agreement”), among the Company and the initial purchasers of the Notes (the “Initial Purchasers”), to use its reasonable best efforts to register the Notes under the Securities Act of 1933, as amended (the “Securities Act”), so as to allow holders of the Notes to exchange the Notes for the same principal amount of new notes (the “Exchange Notes”) with substantially identical terms, except that the Exchange Notes will generally be freely transferable under the Securities Act. In addition, the Company agreed to file, under certain circumstances, a shelf registration statement to cover resales of the Notes. If the Company fails to satisfy these obligations and its other obligations as set forth in the Registration Rights Agreement, it will be required to pay additional interest to the holders of the Notes. A copy of the Registration Rights Agreement is filed as Exhibit 10.1 hereto.

The information under Item 1.01 is incorporated herein by reference.
