ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

Second Lien Senior Secured Notes Indenture

On November 19, 2013, Appvion, Inc. (the “Company”) issued $250,000,000 aggregate principal amount of its 9.000% Second Lien Senior Secured Notes due 2020 (the “Notes”). The Notes mature on June 1, 2020 and will accrue interest from the issue date at a rate of 9.000% per year, payable in cash semi-annually in arrears on each June 1 and December 1, beginning on June 1, 2014 The Notes were issued pursuant to an indenture, dated as of November 19, 2013 (the “Indenture”), by and among the Company, each of the guarantors identified therein (collectively, the “Guarantors”), and U.S. Bank National Association, as trustee (in such capacity, the “Trustee”) and collateral agent (in such capacity, the “Collateral Agent”).

The Company’s obligations under the Notes are guaranteed (the “Guarantees”) by the Guarantors, which include the Company’s parent company, Paperweight Development Corp. (“PDC”), the Company’s Canadian subsidiary, Appvion Canada, Ltd. (“Appvion Canada”), and any of the Company’s other existing and future domestic and foreign subsidiaries that become guarantors or borrowers under the Company’s $435 million senior secured credit facilities (the “Senior Secured Credit Facilities”), established pursuant to a first lien credit agreement by and among the Company, PDC and other guarantors party thereto, and a syndicate of banks and other financial institutions, with Jefferies Finance LLC as administrative agent, and Fifth Third Bank as revolver agent, swing line lender and L/C issuer. The Guarantees are second priority senior secured obligations of the Guarantors.

The Notes rank equally in right of payment with all of the Company’s senior debt and will be senior in right of payment to all existing and future Subordinated Indebtedness (as defined in the Indenture) of the Company. The Guarantees rank equally in right of payment with all of each Guarantor’s senior debt and will be senior in right of payment to all existing and future Subordinated Indebtedness (as defined in the Indenture) of that Guarantor.

The Notes and the Guarantees will have the benefit of the second-priority security interest in the Collateral (as defined in the Indenture). The Collateral consists, subject to certain exceptions as set forth in the Indenture, of substantially all of the Company’s and the Guarantors’ property and assets that secure the Company’s and the Guarantors’ obligations under the Senior Secured Credit Facilities.

On or after December 1, 2016, the Company, at its option, may redeem the Notes upon the terms, at the redemption prices and upon notice as described in the Indenture. With limited exceptions, prior to that date, the Company may redeem the Notes only upon payment of a Make-Whole Price (as defined in the Indenture).

The Indenture governing the Notes contains covenants that, among other things, restrict the Company’s and PDC’s ability, and the ability of the Company’s restricted subsidiaries, to:

These covenants are subject to important exceptions and qualifications set forth in the Indenture.

If the Company experiences certain change of control events, as described in the Indenture, the Company must offer to repurchase the Notes at 101% of the principal amount, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date. If the Company sells assets under certain circumstances described in the Indenture, and subject to certain exceptions, the Company must offer to repurchase the Notes at 100% of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date.

The Indenture provides for customary events of default. In the case of an event of default arising from specified events of bankruptcy or insolvency, all outstanding debt will become due and payable immediately without further action or notice. If any other event of default under the Indenture occurs or is continuing, the Trustee or holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.

The Notes were issued in reliance upon Section 4(2) of the Securities Act of 1933, as amended (the “Securities Act”), and Regulation S under the Securities Act. The Notes and the Guarantees have not been registered under the Securities Act, and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.
