Exhibit 10.25

WAIVER AND FIFTH AMENDMENT TO CREDIT AGREEMENT

This WAIVER AND FIFTH AMENDMENT TO CREDIT AGREEMENT (this “Agreement”) is made as of August 23, 2012 and entered into by and among Diamond Foods, Inc., (the “Borrower”), the Subsidiaries of the Borrower identified on the signature pages hereto as guarantors (collectively, the “Guarantors”), Bank of America, N.A., as Administrative Agent (in such capacity, the “Administrative Agent”), and the lenders party hereto (collectively, the “Lenders”). Capitalized terms used herein and not otherwise defined shall have the meanings ascribed thereto in the Credit Agreement (defined below).

RECITALS

A. The Loan Parties, the Lenders and the Administrative Agent have entered into that certain Credit Agreement dated as of February 25, 2010 (as amended, restated, supplemented or otherwise modified, the “Credit Agreement”), pursuant to which the Lenders have agreed to make the Loans and other extensions of credit, all upon the terms and conditions set forth in the Credit Agreement.

B. Kettle Foods, Inc. is party to a lease of certain equipment dated May 1, 2011 (the “Kettle US Lease”). The Kettle US Lease was initially classified as an operating lease for accounting purposes. The Loan Parties and their advisors have since concluded that the Kettle US Lease should have been classified as a capital lease.

C. Certain Events of Default have occurred and, in certain cases, are continuing as a result of the Kettle US Lease. Specifically, Events of Default may exist or have existed as a result of (i) the Loan Parties’ exceeding of the aggregate amount of Indebtedness permitted under Section 7.03(e) of the Credit Agreement from and after May 1, 2011 as a result of the Kettle US Lease, (ii) the Loan Parties’ having made, or been deemed to make, representations regarding the absence of Defaults notwithstanding the foregoing Defaults, and (iii) the Loan Parties’ failure to notify the Administrative Agent and the Lenders of the foregoing Defaults (collectively, the “Acknowledged Events of Default”).

D. The Loan Parties have requested that the Required Lenders and the Administrative Agent permanently waive the Acknowledged Events of Default and agree to certain amendments to the Credit Agreement.

E. The Required Lenders and the Administrative Agent are willing to agree to such waiver and amendments subject to the terms and conditions set forth in this Agreement.

AGREEMENT

NOW, THEREFORE, in consideration of the foregoing, the parties agree as follows:

1. Existing Defaults. Each of the Loan Parties acknowledges that the Acknowledged Events of Default have occurred and are continuing.

2. Waiver. Subject to the other terms and conditions of this Agreement, the Administrative Agent and the Required Lenders hereby permanently waive the Acknowledged Events of Default as well as the right to exercise any rights or remedies that the Administrative Agent or any Lender has or may have had exclusively with respect thereto. This waiver is limited solely to the Acknowledged Events of Default, and nothing contained in this Agreement shall be deemed to constitute a waiver of any other rights or remedies the Administrative Agent or any Lender may have under the Credit Agreement or any other Loan Documents or under applicable law. Nothing herein shall modify or affect the obligations of

Each Loan Party intends the foregoing release to cover, encompass, release and extinguish, among other things, all claims and matters that might otherwise be reserved by California Civil Code Section 1542, which provides as follows:

“A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.”

Notwithstanding the foregoing, this Section 8 shall not constitute a release of the performance by the Administrative Agent or any Lender after the date hereof of their respective express obligations under the Loan Documents.

9. Covenant Not to Sue. Each Loan Party, on behalf of itself and its successors, assigns, and other legal representatives, hereby absolutely, unconditionally and irrevocably, covenants and agrees with and in favor of each Releasee that it will not sue (at law, in equity, in any regulatory proceeding or otherwise) any Releasee on the basis of any claim released, remised and discharged by such Loan Party pursuant to Section 8 above. If any Loan Party or any of its successors, assigns or other legal representations violates the foregoing covenant, such Loan Party, for itself and its successors, assigns and legal representatives, agrees to pay, in addition to such other damages as any Releasee may sustain as a result of such violation, all attorneys’ fees and costs incurred by any Releasee as a result of such violation.

10. Payment of Fees and Expenses. The Loan Parties shall reimburse the Administrative Agent and each Lender for all fees and expenses of the Administrative Agent and each Lender, in accordance with the terms and conditions of the Credit Agreement, (including without limitation, all reasonable fees and expenses of counsel to the Administrative Agent and counsel to each Lender) incurred in connection with the Loan Documents, including without limitation this Agreement.

11. Loan Documents Unaffected. Except as otherwise specifically provided herein, all provisions of the Credit Agreement and the other Loan Documents shall remain in full force and effect and be unaffected hereby.
