Annex A to Assumption

and Amendment Agreement

AMENDED AND RESTATED

INSTALLMENT NOTE

 

 

FOR VALUE RECEIVED, WEYERHAEUSER COMPANY , a Washington corporation (the “ Borrower ”) and the parent company of the Initial Borrower referred to below, hereby executes this amended and restated installment note (“ Installment Note ”) and promises to pay to the order of MeadWestvaco Timber Note Holding Company II, LLC, a Delaware limited liability company (and the assignee of MWV Community Development and Land Management, LLC, a Delaware limited liability company (the “ Initial Holder ”)) or its permitted assignees (“ Holder ”), the principal sum of Eight Hundred and Sixty Million and no/100ths Dollars ($860,000,000) (“ Principal Sum ”) together with interest at the rate set forth in Section 1 below. This Installment Note will be unsecured and unsubordinated indebtedness of the Borrower and will rank equally with all of the Borrower’s other unsecured and unsubordinated indebtedness from time to time outstanding. Capitalized terms (and, in the case of “subsidiary,” lower-cased terms) shall have the meanings ascribed to such terms in Article 4 of Appendix A to this Installment Note, which is attached hereto and made a part hereof (“ Appendix A ”); for the avoidance of doubt, the term “Installment Note” shall refer collectively to this installment note and Appendix A.

This Installment Note amends and restates and replaces and supersedes in its entirety the Installment Note, dated December 6, 2013, made by Plum Creek Timberlands, L.P. (the “ Initial Borrower ”) to the order of the Initial Holder (the “ Original Installment Note ”).

1. Interest .

(a) Subject to Section 19 below and the remainder of this Section 1 , the unpaid Principal Sum shall bear interest from December 6, 2013 until paid in full at a fixed rate per annum equal to 5.207% (the “ Interest Rate ”)

(b) Interest at the rate or rates provided herein shall be payable on each Payment Date (defined below). All interest payable under the terms of this Installment Note shall be calculated on the basis of twelve (12) 30-day months in a 360-day year.

(c) If any amount of the Principal Sum is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount shall thereafter bear interest at a rate per annum at all times equal to the interest rate then in effect plus two percent (2%) (the “ Default Rate ”) to the fullest extent permitted by applicable Laws. Upon the request of Holder, if any amount (other than the Principal Sum) payable by the Borrower hereunder is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, then such amount shall thereafter bear interest at the Default Rate to the fullest extent permitted by applicable Laws. Upon the request of Holder, while any other Event of Default exists, the Borrower shall pay interest on the obligations owing under this Installment Note (including the Principal Sum) at the

Default Rate to the fullest extent permitted by applicable Laws. Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable on demand.

2. Payments and Maturity .

(a) Interest on the unpaid Principal Sum shall be due and payable semi-annually, on the first day of each May and November (each a “ Payment Date ”), commencing on May 1, 2014, and continuing on each Payment Date thereafter through and until the Maturity Date.

(b) The entire unpaid Principal Sum, together with all accrued and unpaid interest, shall mature and be due and payable in full on December 6, 2023 (“ Original Maturity Date ” and as extended with respect to all or a portion of the Principal Sum in accordance with the remainder of this paragraph, the “ Maturity Date ”). Notwithstanding the Original Maturity Date, if (i) at least 180 days prior to the Original Maturity Date, Holder provides written notice to the Borrower of Holder's request to extend the Original Maturity Date with respect to all or a portion not less than $200,000,000 of the Principal Sum (an “ Extension Request ”), and (ii) Borrower consents in writing to such Extension Request, such consent to be given or withheld, subject to the second succeeding sentence, in Borrower’s sole discretion, then, with respect to the Principal Sum or, if applicable, the portion of the Principal Sum specified in the Extension Request or an amount otherwise consented to by Borrower, the Original Maturity Date shall automatically be extended to the date so requested by Holder or, if earlier, at Borrower’s election, the expected Maturity Date of any Refinancing Indebtedness (as defined below). For all purposes hereunder, such date shall thereafter be the “Maturity Date” with respect to the Principal Sum or applicable portion thereof, as the case may be, provided that any portion of the Principal Sum as to which the Original Maturity Date has not been extended as provided in the immediately preceding sentence shall remain due and payable on the Original Maturity Date. The Borrower agrees that it shall consent to an Extension Request if (i) at the time of the Extension Request the Borrower intends to refinance all or a portion not less than $200,000,000 of this Installment Note on or prior to the Original Maturity Date with the proceeds of new indebtedness for borrowed money (including, without limitation, indebtedness evidenced by bonds, notes or similar Instruments or advanced under a bank credit facility) that has a term greater than or equal to 5 years from its issuance (“ Refinancing Indebtedness ”) (it being understood that the requirement that the Borrower consent to such Extension Request shall only apply to an amount of the Principal Sum equal to the amount of the contemplated Refinancing Indebtedness) and (ii) Holder consents that the terms of this Installment Note, other than interest rate which shall be determined as set forth below, will be amended to be substantially consistent with the terms that would reasonably be expected to apply to the contemplated Refinancing Indebtedness. Borrower covenants to respond in writing to any Extension Request no later than 60 days prior to the Original Maturity Date in accordance with Section 13 below and the parties agree to cooperate to amend this Installment Note in a manner consistent with this paragraph upon the extension of the Maturity Date in accordance herewith. In the event that the Maturity Date is extended in accordance with this paragraph, the Interest Rate shall be reset, as to the applicable portion of the Principal Sum, to the Extension Interest Rate on a date to be agreed upon by Holder and Borrower, but in no event shall such date be later than the Original Maturity Date. For purposes hereof, “ Extension Interest Rate ” means the all-in yield (including interest rate and original issue discount, and 50% of other customary fees and expenses, including arrangement and similar fees) Borrower would have been expected to incur in connection with Refinancing Indebtedness with a maturity of the Maturity Date as extended pursuant to this paragraph. Notwithstanding the foregoing, if this Installment Note has been pledged to one or more Eligible Assignees to secure Indebtedness of the Holder, then in no event shall an extension of the Original Maturity Date (or, if applicable, the then current Maturity Date) become effective unless and until (x) such secured Indebtedness of the Holder has been repaid in full in cash, (y) the beneficiary(ies) of such pledge (or the requisite subset thereof or an agent acting on their behalf)

shall have consented in writing to such extension or (z) such extension is permissible in accordance with the terms of such Indebtedness.

(c) If any payment under this Installment Note is due on a day which is not a Business Day, such payment shall be due and payable on the next succeeding Business Day as if made on the date such payment was due and without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day.

3. Application and Place of Payments . All payments made on account of this Installment Note shall be applied, first, to the payment of any unpaid and accrued enforcement and collection costs incurred by Holder, if any, second, to the payment of accrued and unpaid interest, and the remainder, if any, shall be applied to the unpaid Principal Sum. All payments on account of this Installment Note shall be paid in immediately available funds via wire transfer to an account designated in writing by Holder.

4. Optional Prepayment .

(a) The Borrower may prepay this Installment Note in whole or in part for cash at 100% of the Principal Sum or portion thereof prepaid, plus accrued but unpaid interest, if any, to, but not including, the prepayment date, plus the Breakage Amount (if any) as follows: (i) at any time on or after October 1, 2023 (which date shall be modified as agreed by the Borrower and Holder in connection with an extension pursuant to Section 2(b)) or (ii) at any time in the event MeadWestvaco Corporation or one of its wholly-owned Subsidiaries ceases to be the sole beneficial and legal owner of this Installment Note (excluding, for the avoidance of doubt, any pledge of this Installment Note to one or more Eligible Assignees); or

(b) At any time during the 180-day period following receipt by the Borrower of notice from Holder that Holder intends to withhold its consent to any amendment or waiver of this Installment Note (or, with respect to the covenants and the representations and warranties that have been incorporated by reference herein pursuant to Sections 1.01, 2.01 and 3.01 of Appendix A, that Holder intends to withhold its consent to any amendment to, or amendment and restatement of, the 2013 Weyerhaeuser Term Loan Agreement, or to any credit agreement that replaces or refinances the 2013 Weyerhaeuser Term Loan Agreement, where such consent of Holder is required by the terms of this Installment Note in order for the covenants or representations and warranties that have been incorporated by reference herein to be updated to correspond to those in such amendment to, or amendment and restatement of, the 2013 Weyerhaeuser Term Loan Agreement or such replacement credit agreement) that was requested by the Borrower and approved by any Eligible Assignees (or, as applicable, the requisite majority of financing sources for whom an Eligible Assignee serves as agent or trustee) to which this Installment Note has been pledged (an “ Optional Prepayment Event ”), the Borrower may prepay this Installment Note in whole but not in part for cash at 100% of the Principal Sum, plus accrued but unpaid interest, if any, to, but not including, the prepayment date, plus the Breakage Amount (if any); provided , however , that the Borrower’s right to prepay the Note pursuant to this paragraph 4(b) shall terminate upon the 181 ^st day after an Optional Prepayment Event shall have occurred.

The Borrower shall not otherwise have the right to prepay this Installment Note unless Holder shall have granted its prior written consent, which consent may be given or withheld at Holder’s sole discretion.

5. Purchase Agreement and Related Transactions . The Initial Borrower, as purchaser, and Initial Holder, as seller, are parties to a Master Purchase and Sale Agreement dated as of October 28, 2013 (as such agreement may be subsequently amended, the “ Purchase Agreement ”), pursuant to which the

Initial Borrower purchased from Initial Holder the Installment Sale Timberlands (as defined in the Purchase Agreement), which are more particularly described in such Purchase Agreement, and the Initial Borrower issued the Original Installment Note in payment of the purchase price for the Installment Sale Timberlands.

(a) Non-Payment .

(a) Unless otherwise defined herein, terms defined in the Installment Note and used herein shall have the meanings assigned to such terms in the Installment Note.

(b) The following terms shall have the following meanings:

“ Additional Assumption Agreement ” means any agreement entered into by WNR Company after the date hereof pursuant to which WNR Company assumes payment obligations in respect of any indebtedness of the Company.

“ Assumed Debt ” means any indebtedness of the Company the payment obligations in respect of which shall have been assumed by WNR Company pursuant to one or more Assumption Agreements.

“ Assumed Debt Agreement ” means any indenture, credit agreement, note purchase agreement or other agreement, if any, pursuant to which the Company has incurred or will incur Assumed Debt and any note, instrument, agreement or other document evidencing or governing such Assumed Debt.

(a) WNR Company hereby agrees with the Holder that the Installment Note Parties shall have rights and claims enforceable against WNR Company for payment of all or a portion of the Installment Note Obligations to the same extent that the Assumed Debt Parties (as opposed to the Company) have rights and claims, if any, enforceable against WNR Company for payment of all or any portion of the Assumed Debt (including accrued and unpaid interest and any related obligations in respect of premiums, fees and indemnities) pursuant to or by reason of any Assumption Agreement (such rights and claims of the Assumed Debt Parties, the “ Assumed Debt Claims ”), as if WNR Company and the Company had entered into an assumption agreement in respect of the Installment Note Obligations on the same terms as such Assumption Agreement that is the subject of the Assumed Debt Claims (such rights and claims of the Installment Note Parties, the “ Installment Note Claims ”).

(iii)      a final adjudication by a court or arbitrator that WNR Company is liable to any Assumed Debt Party for such Assumed Debt Claim.

WNR Company’s obligations under this Agreement shall in all respects be continuing, absolute, unconditional and irrevocable, and shall remain in full force and effect until all of the Installment Note Obligations (other than contingent expense reimbursement and indemnification obligations) have been paid in full and all commitments under the Installment Note have been terminated. WNR Company agrees that any Installment Note Claims due and owing by WNR Company hereunder will be paid strictly in accordance with the terms of this Agreement, the Installment Note and the other Loan Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Company or WNR Company with respect thereto. The liability of WNR Company under this Agreement shall be absolute, unconditional and irrevocable irrespective of:

(a) any change in the time, manner, or place of payment of, or in any other term of, the Installment Note Obligations, the Installment Note or any other documents related thereto or any other extension, compromise or renewal of the Installment Note Obligations;

(b) any reduction, limitation, impairment or termination of the Installment Note Obligations for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to (and WNR Company hereby waives any right to or claim of) any defense or setoff, counterclaim, recoupment, or termination whatsoever by reason of the invalidity, illegality, irregularity, compromise, unenforceability of, or any other event or occurrence affecting, the Installment Note Obligations;

(c) any amendment to, rescission, waiver or other modification of, or any consent to departure from, any of the terms of Installment Note or any of the other Loan Documents;

(e) any other circumstance which might otherwise constitute a defense available to, or a legal or equitable discharge of, the Company or WNR Company.

Notwithstanding the agreements by WNR Company in respect of the Installment Note Claims pursuant to Section 2(a), as between the Company and the holders of any Installment Note Obligations, the Company shall continue to be the primary obligor with respect to the Installment Note Obligations and the Company shall not be released from its obligations under the Installment Note Obligations as a result of this Agreement.
