Item 7.01 Regulation FD Disclosure

On July 2, 2014, Verso Paper Holdings LLC (“Verso Holdings”), an indirect wholly-owned subsidiary of Verso Paper Corp. (“Verso” and, together with Verso Holdings, the “Registrants”), and Verso Paper Inc., a wholly owned subsidiary of Verso Holdings (together with Verso Holdings, the “Issuers”) launched offers to exchange (i) new Second Priority Adjustable Senior Secured Notes (the “New Second Lien Notes”) and warrants issued by Verso that will be mandatorily convertible into shares of Verso common stock immediately prior to Verso’s acquisition of NewPage Holdings Inc. (“Warrants”) for any and all of the Issuers’ outstanding 8.75% Second Priority Senior Secured Notes due 2019 (the “Old Second Lien Notes”) and (ii) new Adjustable Senior Subordinated Notes (the “New Subordinated Notes”) and Warrants for any and all of the Issuers’ outstanding 11 ³⁄₈% Senior Subordinated Notes due 2016 (the “Old Subordinated Notes”).

In connection with the exchange offers for the Old Second Lien Notes and the Old Subordinated Notes (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 of the Exchange Offers and Consent Solicitations are set forth in the Issuers’ Confidential Offering Memorandum and Consent Solicitation Statement, dated July 2, 2014 (the “Offering Memorandum”). A copy of the news release announcing the Exchange Offers and Consent Solicitations is included as Exhibit 99.1 to this report and is incorporated by reference herein.

The Registrants are disclosing under Item 7.01 of this Current Report on Form 8-K the foregoing information and the information included as Exhibit 99.2 to this report, which information is incorporated by reference herein. This information, which has not been previously reported, is excerpted from the Offering Memorandum that is being disseminated in connection with the Exchange Offers described above.

This information (except insofar as such information is also set forth under Item 8.01 below) shall not deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, and shall not be deemed to be incorporated by reference into any of the Registrants’ filings under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, whether made before or after the date hereof and regardless of any general incorporation language in such filings, except to the extent expressly set forth by specific reference in such a filing.
