Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

Item 1.01. Entry into a Material Definitive Agreement.

The description in Item 2.03 is hereby incorporated by reference into this Item 1.01.

Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On February 11, 2014, NewPage Corporation (the “Borrower”), a wholly-owned subsidiary of NewPage Holdings Inc. (“NewPage” or the “Company”), entered into a $750 million senior secured term loan facility (the “Term Loan Facility”) and a $350 million senior secured asset-backed revolving credit facility (the “ABL Facility”). The Term Loan Facility will be used to refinance the indebtedness under the Borrower’s existing $500 million senior secured exit term loan credit facility, to fund a special distribution to NewPage’s stockholders (the “Special Distribution”) in an amount of approximately $243 million, to pay certain transaction costs and for general corporate purposes. The ABL Facility will be used to replace the Borrower’s existing $350 million revolving credit facility for general corporate purposes and to pay certain transaction costs and expenses of the pending merger between NewPage and Verso Paper Corp. (“Verso”), but no amounts will be drawn under the ABL Facility on the closing date other than certain letters of credit.

The Term Loan Facility matures on February 11, 2021 and the ABL Facility matures on February 11, 2019. The Term Loan Facility requires no amortization payments until the eighteen month anniversary of the closing date, and will thereafter require quarterly amortization payments, in an amount equal to (1) 1.25% per quarter until the three year anniversary of the closing date, (2) 1.875% per quarter until the four year anniversary of the closing date, and (3) 2.50% per quarter until the maturity date, with the balance due on the maturity date.

Availability under the Term Loan Facility and the ABL Facility is subject to customary borrowing conditions. The ABL Facility includes a $200 million sub-limit for letters of credit and a $30 million sub-limit for swingline loans. At closing, $750 million was drawn under the Term Loan Facility and no amounts were drawn under the ABL Facility other than certain letters of credit. The Borrower had approximately $316 million available for additional borrowings under the ABL Facility, subject to borrowing base limitations, as reduced by outstanding letters of credit.

Amounts drawn under the Term Loan Facility bear annual interest at either the LIBOR rate plus a margin of 8.25% or at a base rate plus a margin of 7.25%. Amounts drawn under the ABL Facility bear annual interest at either the LIBOR rate plus a margin of 1.75% to 2.25% or at a base rate plus a margin of 0.75% to 1.25%. The interest rate margins on the ABL Facility are subject to adjustments based on the average availability of the ABL Facility. The initial margins for borrowings under the ABL Facility are 2.00% in the case of LIBOR rate loans and 1.00% in the case of base rate loans. The commitment fee payable on the unused portion of the ABL Facility equals 0.375% or 0.50% based on the average availability of the ABL Facility. The Borrower has also agreed to pay customary letter of credit fees.

The Borrower has the right to prepay loans under the Term Loan Facility at any time without premium or penalty, other than customary “breakage” costs with respect to LIBOR rate loans, subject, however, to a prepayment premium for optional prepayments of the Term Loan Facility with a new or replacement term loan facility with an “effective” interest rate less than that applicable to the Term Loan Facility equal to (1) 3.00% if prepaid prior to the first anniversary of the closing date, (2) 2.00% if prepaid on or after the first anniversary of the closing date and prior to the second anniversary of the closing date and (3) 1.00% if prepaid on or after the second anniversary of the closing date and prior to the third anniversary of the closing date. However, if the merger agreement (the “Merger Agreement”) entered into with Verso and Verso Merger Sub Inc. on January 3, 2014 is terminated in accordance with its terms, the Term Loan Facility may be prepaid with no premium or penalty within 30 days. Loans under the ABL Facility may be prepaid at any time without premium or penalty, other than customary “breakage” costs with respect to LIBOR rate loans.

The Term Loan Facility is subject to mandatory prepayments in amounts equal to (1) 100% of the net cash proceeds of indebtedness by the Borrower or any of its subsidiary Guarantors (as defined below) (other than indebtedness permitted under the Term Loan Facility), (2) 100% of the net cash proceeds of any non-ordinary course sale or other disposition of assets by the Borrower or any of its subsidiary Guarantors (including as a result of casualty or

condemnation) (with customary exceptions, thresholds, and reinvestment rights of up to 12 months or 18 months if contractually committed to within 12 months), and (3) 75% of “excess cash flow” for each fiscal year beginning with the fiscal year ending December 31, 2015, subject to possible step-downs based on total net first lien leverage ratio thresholds.

The Term Loan Facility and the ABL Facility are fully and unconditionally guaranteed on a joint and several basis by all of the Borrower’s existing and future direct and indirect wholly owned material domestic restricted subsidiaries, subject to certain exceptions, and by NewPage Investment Company LLC (“Holdings”), the Borrower’s direct parent (collectively, the “Guarantors”). Amounts outstanding under the ABL Facility and Term Loan Facility are secured by substantially all of the assets of the Borrower and the Guarantors, subject to certain exceptions. The security interest with respect to the ABL Facility will consist of a first-priority lien with respect to most inventory, accounts receivable, bank accounts, and certain other assets of the Borrower and the Guarantors (the “ABL Priority Collateral”) and a second-priority lien with respect to all other collateral (the “Term Loan Priority Collateral”). The security interest with respect to the Term Loan Facility will consist of a first-priority lien with respect to the Term Loan Priority Collateral and a second-priority lien with respect to the ABL Priority Collateral.

The Term Loan Facility requires the Borrower to maintain a maximum total net leverage ratio on the last day of any fiscal quarter when loans are outstanding under the Term Loan Facility. The initial maximum total net leverage ratio threshold shall be 4.10 to 1.00 through the fiscal quarter ending September 30, 2014, stepping down every year thereafter to a maximum total net leverage ratio threshold of 3.50 to 1.00 for the fiscal quarter ending December 31, 2019 and thereafter. Under the ABL Facility, the Borrower is subject to a springing minimum fixed charge coverage ratio of 1.00 to 1.00 at any time when excess availability is less than the greater of (a) 10% of the lesser of (i) the borrowing base at such time and (ii) the aggregate amount of commitments at such time or (b) $20 million.

The Term Loan Facility and the ABL Facility contain certain additional covenants that, among other things, and subject to certain exceptions, restrict the Borrower’s and its restricted subsidiaries’ ability to incur additional debt or liens, pay dividends, repurchase common stock, prepay other indebtedness, sell, transfer, lease, or dispose of assets and make investments in or merge with another company. The Term Loan Facility and the ABL Facility also contain covenants applicable to Holdings that, among other things, and subject to certain exceptions, limit Holdings’ ability to incur additional debt or liens and require Holdings to continue to directly own 100% of the equity interests of the Borrower. The Term Loan Facility and the ABL Facility provide for customary events of default, including a cross-event of default provision in respect of any other existing debt instruments having an aggregate principal amount exceeding $50 million, subject to applicable threshold, notice and grace period provisions. If an event of default occurs, the lenders under the Term Loan Facility or the ABL Facility, as applicable, are entitled to accelerate the advances made thereunder and exercise rights against the collateral. The Term Loan Facility and the ABL Facility expressly permit the transactions contemplated by the Merger Agreement.

The foregoing descriptions of the Term Loan Facility and the ABL Facility are qualified in their entirety by the full text of such agreements, copies of which are filed as exhibits to this Current Report on Form 8-K and are incorporated herein by reference.
