WAIVER AND AMENDMENT NO. 3

WAIVER AND AMENDMENT NO. 3 (this “Amendment”), dated as of March 21, 2012, under and to the ABL Credit Agreement dated as of December 9, 2010 (as heretofore amended, the “Credit Agreement”) among AbitibiBowater Inc., a Delaware corporation (“AbitibiBowater”), the Subsidiaries of AbitibiBowater party thereto (together with AbitibiBowater, collectively, the “Borrowers”), the Lenders party thereto from time to time and Citibank, N.A., as Administrative Agent (the “Administrative Agent”) and Collateral Agent.

WHEREAS, AbitibiBowater has advised the Administrative Agent and the Lenders that it may acquire all or a portion of the outstanding common shares of Fibrek Inc., a Canadian corporation listed on the Toronto Stock Exchange (“Fibrek” and, together with its Subsidiaries, the “Fibrek Group Members”); and

WHEREAS, the Borrowers have requested that the Lenders (i) waive certain Events of Default that may arise under Section 11.01(f) of the Credit Agreement and (ii) make certain amendments to the Credit Agreement;

NOW THEREFORE, the parties hereto agree as follows:

Section 1. Defined Terms; References. Unless otherwise specifically defined herein, each term used herein that is defined in the Credit Agreement has the meaning assigned to such term in the Credit Agreement. Each reference to “hereof”, “hereunder”, “herein” and “hereby” and each other similar reference and each reference to “this Agreement” and each other similar reference contained in the Credit Agreement shall, after this Amendment becomes effective, refer to the Credit Agreement as amended hereby.

Section 2. Limited Waiver. The Lenders hereby waive (the “Waiver”) any Event of Default which may arise under Section 11.01(f) of the Credit Agreement, solely to the extent that the Indebtedness that would give rise to such Event of Default is Indebtedness of Fibrek Group Members (any such Indebtedness that would give rise to such an Event of Default, “Applicable Fibrek Indebtedness”); provided, that the Waiver shall automatically expire and cease to be effective on the earliest of (x) the occurrence of any date on which the sum of (i) the aggregate amount of cash and Permitted Investments held by the Loan Parties plus (ii) Excess Availability shall be less than the aggregate outstanding principal amount of all Applicable Fibrek Indebtedness, (y) the date which is 180 days after the date on which Fibrek first becomes a Subsidiary of AbitibiBowater and (z) October 31, 2012. The Waiver shall be limited precisely as written, and shall not extend to any other Default or Event of Default under any other provision of the Credit Agreement or to any Default or Event of Default which may exist (including under Section 11.01(f) of the Credit Agreement) after the expiration of this Waiver. For the avoidance of doubt, any default or other circumstance that may exist under or with respect to Indebtedness of any Person that is not a Fibrek Group Member shall not be subject to the Waiver.

Section 3. Amendments to the Credit Agreement. The Credit Agreement is hereby amended as follows:

(a) Clause (a) of the definition of “U.S. Subsidiary Guarantors” in Section 1.01 of the Credit Agreement is amended by inserting “(other than a Domestic Subsidiary that is a Subsidiary of a Foreign Subsidiary)” immediately following “Domestic Subsidiary”.

(b) Section 9.09(b) of the Credit Agreement is amended by inserting “(other than a Domestic Subsidiary that is a Subsidiary of a Foreign Subsidiary)” immediately following “Domestic Subsidiary” in clauses (i) and (ii) thereof.

(c) Section 10.01(i) of the Credit Agreement is amended by replacing “$100,000,000” with “$160,000,000”.

(d) Section 10.02 of the Credit Agreement is amended by (A) deleting “and” at the end of clause (xix), (B) deleting “.” at the end of clause (xx) and replacing it with “; and” and (C) inserting a new clause (xxi) as follows:

“(xxi) Liens in favor of a Loan Party securing Indebtedness permitted under Section 10.01(c) and which, if on assets of a Loan Party, have been subordinated to the Liens of the Collateral Agent on terms reasonably satisfactory to the Collateral Agent.”

Section 4. Representations of the Borrowers. Each of the Borrowers represents and warrants that (a) the representations and warranties of the Borrowers set forth in Section 8 of the Credit Agreement and in the Loan Documents will be true and correct in all material respects on and as of the Amendment Effective Date (as defined below) with the same effect as though such representations and warranties had been made on and as of the Amendment Effective Date (it being understood and agreed that (x) any representation or warranty which by its terms is made as of a specified date shall be required to be true and correct in all material respects only as of such specified date and (y) any representation or warranty that is qualified as to “materiality”, “Material Adverse Effect” or similar language shall be true and correct in all respects on such date) and (b) no Default or Event of Default will have occurred and be continuing on the Effective Date.

Section 5. Counterparts. This Amendment may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the same instrument. Delivery of an executed counterpart hereof by facsimile or electronic transmission shall be as effective as delivery of an original executed counterpart hereof.

Section 6. Effectiveness. This Amendment shall become effective on the date when the following conditions have been met (the “Amendment Effective Date”):

(a) The Administrative Agent shall have received from each of the Loan Parties and the Lenders party hereto, which Lenders constitute the Required Lenders, (i) a counterpart hereof signed by such party or (ii) evidence satisfactory to the Administrative Agent (which may include a facsimile or other electronic transmission) that such party has signed a counterpart of this Amendment; and

(b) The Administrative Agent shall have received (i) for the account of each Lender consenting hereto on or prior to such date, a consent fee in an amount equal to 0.025% of the sum of (A) such Lender’s U.S. Facility Commitment plus (B) such Lender’s Canadian Facility Commitment, in each case as of the Amendment Effective Date and (ii) all out-of-pocket costs and expenses required to be paid by the Borrowers pursuant to Section 13.01 of the Credit Agreement for which invoices have been presented not later than the Business Day preceding the Amendment Effective Date.

Section 7. Reference To and Effect Upon the Loan Documents.

(a) Except as expressly set forth herein, all terms, conditions, covenants, representations and warranties contained in the Credit Agreement and the other Loan Documents and all rights of the Agents, the Issuing Lenders, the Swingline Lenders and the Lenders and all obligations of the Loan Parties, shall remain in full force and effect. The Loan Parties hereby confirm that the Credit Agreement and the other Loan Documents are in full force and effect.

(b) This Amendment shall constitute a Loan Document for all purposes of the Loan Documents.
