ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On June 28, 2013, Appvion, Inc. (“Appvion” or the “Company”), in connection with the settlement of its (i) cash tender offer (the “Tender Offer”) for any and all of its outstanding 10.50% Senior Secured Notes due 2015 (the “First Lien Notes”) and (ii) consent solicitation (the “Consent Solicitation”) for effecting certain amendments to the indenture governing the First Lien Notes, dated as of February 8, 2010, by and among the Company, the guarantor parties thereto and U.S. Bank National Association, as trustee and collateral agent (the “First Lien Notes Indenture”), entered into a First Supplemental Indenture (the “First Lien Supplemental Indenture”) to the First Lien Notes Indenture.

The First Lien Supplemental Indenture amended the First Lien Notes Indenture by, among other things, eliminating substantially all of the restrictive covenants and certain events of default contained therein, relieving Appvion of certain of its obligations relating to merger, consolidation, or sale of assets, releasing all of the collateral securing the First Lien Notes and modifying certain other related provisions contained in the First Lien Notes Indenture.

The foregoing description of the First Lien Supplemental Indenture does not purport to be complete and is qualified in its entirety by reference to the complete text of the First Lien Supplemental Indenture, which is attached as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated herein by reference herein.

ITEM 8.01 OTHER EVENTS

On June 28, 2013, the Company entered into a Fourth Supplemental Indenture (the “Senior Subordinated Supplemental Indenture”) to the indenture governing the Company’s 9.75% Senior Subordinated Notes due 2014, dated as of June 11, 2004, by and among the Company, and each of the guarantors named therein and U.S. Bank National Association, as trustee (as amended, the “Senior Subordinated Notes Indenture”). The amendment allows the Company to designate a Restricted Subsidiary (as defined in the Senior Subordinated Indenture) having no material assets that is a guarantor party to the Senior Subordinated Indenture to be an Unrestricted Subsidiary (as defined in the Senior Subordinated Indenture), and to dissolve such subsidiary without violating the terms of the Senior Subordinated Indenture. Pursuant to Section 9.01 of the Senior Subordinated Indenture, the Company is not required to seek consent of the holders of the Senior Subordinated Notes before entering into the Senior Subordinated Supplemental Indenture.

The foregoing description of the Senior Subordinated Supplemental Indenture does not purport to be complete and is qualified in its entirety by reference to the complete text of the Senior Subordinated Supplemental Indenture, which is attached as Exhibit 4.2 to this Current Report on Form 8-K and is incorporated herein by reference herein.
