On January 13, 2014, Verso Paper Holdings LLC (“Verso Holdings”), a wholly-owned subsidiary of Verso Paper Corp. (together with Verso Holdings, the “Registrants”) and Verso Paper Inc., a subsidiary of Verso Holdings (together with Verso Holdings, the “Issuers”) launched offers to exchange new Second Priority Adjustable Senior Secured Notes (the “New Second Lien Notes”) and new Adjustable Senior Subordinated Notes (the “New Subordinated Notes”) for any and all of their outstanding 8.75% Second Priority Senior Secured Notes due 2019 (the “Old Second Lien Notes”) and 11 ³/₈% Senior Subordinated Notes due 2016 (the “Old Subordinated Notes”), respectively.

In connection with the exchange offers (the “Exchange Offers”), the Issuers will solicit consents to amend the Old Second Lien Notes, the Old Subordinated Notes and the indentures governing the Old Second Lien Notes and the Old Subordinated Notes (the “Consent Solicitations”). The proposed amendments, which will require the consent of a majority in outstanding aggregate principal amount of the Old Second Lien Notes and Old Subordinated Notes, respectively, will eliminate or waive substantially all of the restrictive covenants, eliminate certain events of default, modify covenants regarding mergers and transfer of assets, and modify or eliminate certain other provisions. In addition, the consents with respect to the Old Second Lien Notes will authorize a release of the liens and security interests in the collateral securing the Old Second Lien Notes. In order to be effected, the collateral release must be consented to by the holders of at least two-thirds in outstanding aggregate principal amount of the Old Second Lien Notes.

The terms and conditions to the Exchange Offers and Consent Solicitations are set forth in the Issuers’ confidential offering memorandum and consent solicitation statement, dated January 13, 2014. A copy of the news release announcing the Exchange Offers and Consent Solicitations is attached as Exhibit 99.1 and is incorporated by reference herein.

This information, which has not been previously reported, is excerpted from the Confidential Offering Memorandum and Consent Solicitation Statement that is being disseminated to eligible holders of the Old Second Lien Notes and Old Subordinated Notes in connection with the Exchange Offers described above.
