WHEREAS, pursuant to an Agreement and Plan of Merger, dated as of January 28, 2018, among the New Guarantor, WRKCo, Whiskey Merger Sub, Inc., a Delaware corporation, Kola Merger Sub, Inc., a Delaware corporation, and KapStone Paper and Packaging Corporation, a Delaware corporation, the New Guarantor will become the ultimate parent of the Company;

WHEREAS, the New Guarantor desires to fully and unconditionally guarantee all the monetary obligations of the Company under the Indenture (including obligations to the Trustee) and the full and punctual performance within applicable grace periods of all other obligations of the Company under the Indenture (the “Guarantee”);

WHEREAS, the Company proposes in and by this Fifth Supplemental Indenture to supplement and amend the Indenture in certain respects as it applies to Securities issued thereunder;

WHEREAS, pursuant to Section 901(9) of the Indenture, the Trustee is authorized to execute and deliver this Fifth Supplemental Indenture without the consent of Holders of the Securities; and

WHEREAS, all the conditions and requirements necessary to make this Fifth Supplemental Indenture a valid, binding and legal instrument in accordance with its terms have been performed and fulfilled by the Obligors and the execution and delivery thereof have been in all respects duly authorized by the Obligors.

NOW, THEREFORE, in consideration of the above premises, each party agrees, for the benefit of the others and for the equal and ratable benefit of the Holders of the Securities, as follows:

ARTICLE ONE

REAFFIRMATION AND ACCESSION

SECTION 1.01. Reaffirmation. The Company hereby expressly and unconditionally reaffirms each and every covenant, agreement and undertaking of such party in the Indenture.

SECTION 1.02. Note Guarantee.

(a) The New Guarantor unconditionally guarantees, on a joint and several basis, to each Holder of Securities (including each Holder of Securities issued under the Indenture after the date of this Fifth Supplemental Indenture) and to the Trustee and its successors and assigns, (i) the full and punctual payment of all monetary obligations of the Company under the Indenture (including obligations to the Trustee) and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Company under the Indenture. The New Guarantor further agrees that its obligations hereunder shall be unconditional, irrespective of the absence or existence of any action to enforce the same, the recovery of any judgment against the Company (except to the extent such judgment is paid) or any waiver or amendment of the provisions of the Indenture or the Securities to the extent that any such action or any similar action would otherwise constitute a legal or equitable discharge or defense of the New Guarantor (except that such waiver or amendment shall be effective in accordance with its terms).

(b) The New Guarantor further agrees that its Guarantee constitutes a guarantee of payment, performance and compliance and not merely of collection.

(c) The New Guarantor further agrees to waive presentment to, demand of payment from and protest to the Company of its Guarantee, and also waives diligence, notice of acceptance of its Guarantee, presentment, demand for payment, notice of protest for nonpayment, the filing of claims with a court in the event of merger or bankruptcy of the Company and any right to require a proceeding first against the Company or any other Person. The obligations of the New Guarantor shall not be affected by any failure or policy on the part of the Trustee to exercise any right or remedy under the Indenture or the Securities of any series.

(d) The obligation of the New Guarantor to make any payment hereunder may be satisfied by causing the Company or another Obligor to make such payment. If any Holder of any Security or the Trustee is required by any court or otherwise to return to the Company or any Obligor or any custodian, trustee, liquidator or other similar official acting in relation to any of the Company or any such Obligor any amount paid by any of them to the Trustee or such Holder, any applicable guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

(e) The New Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder of Securities in enforcing any of their respective rights under its Guarantee.

(f) Any term or provision of this Fifth Supplemental Indenture to the contrary notwithstanding, the maximum aggregate amount of the New Guarantor’s Guarantee shall not exceed the maximum amount that can be hereby guaranteed without rendering this Fifth Supplemental Indenture, as it relates to the New Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

SECTION 1.03. Benefits Acknowledged. The New Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Indenture and that its Guarantee and waivers pursuant to its Guarantee are knowingly made in contemplation of such benefits.

SECTION 1.04. Termination of Guarantee. The Guarantee shall be automatically released and shall terminate upon (i) the merger of the New Guarantor with or into any other Obligor, (ii) the consolidation of the New Guarantor with another Obligor or (iii) the transfer of all or substantially all of the assets of the New Guarantor to another Obligor. At the request of the Company, and subject to Section 102 of the Indenture, the Trustee will execute and deliver any documents, instructions or instruments evidencing any such release.
