Spinco shall provide reasonable assistance to Weyerhaeuser in the preparation of the Statement and shall provide Weyerhaeuser reasonable access at all reasonable times to the personnel, properties, books and records of the Newco Business for such purpose.

(b) Objections; Resolution of Disputes. The Statement shall become final and binding upon the parties on the 30th day following delivery thereof, unless Spinco gives written notice of its disagreement with the Statement (a “Notice of Disagreement”) to Weyerhaeuser prior to such date. Any Notice of Disagreement shall (i) specify in reasonable detail the nature of any disagreement so asserted, and (ii) only include disagreements based on mathematical errors or based on Closing Working Capital not being calculated in accordance with this Section 2.04. If a Notice of Disagreement is received by Weyerhaeuser in a timely manner, then the Statement (as revised in accordance with this sentence) shall become final and binding upon Weyerhaeuser and Spinco on the earlier of (A) the date Weyerhaeuser and Spinco resolve in writing any

differences they have with respect to the matters specified in the Notice of Disagreement, and (B) the date any disputed matters are finally resolved in writing by the Accounting Firm. During the 30-day period following the delivery of a Notice of Disagreement, Weyerhaeuser and Spinco shall seek in good faith to resolve in writing any differences that they may have with respect to the matters specified in the Notice of Disagreement. At the end of such 30-day period, Weyerhaeuser and Spinco shall submit to an independent accounting firm (the “Accounting Firm”) for arbitration any and all matters that remain in dispute and were properly included in the Notice of Disagreement. The Accounting Firm shall be Deloitte & Touche LLP or, if such firm is unable or unwilling to act, such other nationally recognized independent public accounting firm as shall be agreed upon by the parties hereto in writing. Weyerhaeuser and Spinco shall use reasonable efforts to cause the Accounting Firm to render a decision resolving the matters submitted to the Accounting Firm within 30 days of receipt of the submission. Judgment may be entered upon the determination of the Accounting Firm in any court having jurisdiction over the party against which such determination is to be enforced. The cost of any arbitration (including the fees and expenses of the Accounting Firm and reasonable attorney fees and expenses of the parties) pursuant to this Section 2.04 shall be equally shared by Spinco and Weyerhaeuser. Other than the fees and expenses referred to in the immediately preceding sentence, the fees and disbursements of Weyerhaeuser’s independent auditors shall be borne by Weyerhaeuser and the fees and disbursements of Spinco’s independent auditors shall be borne by Spinco.

(c) Adjustment Payment. If the Closing Working Capital is less than $500,000,000, Weyerhaeuser shall, within ten business days after the Statement becomes final and binding on the parties, pay to Spinco the amount by which Closing Working Capital is less than $500,000,000. If the Closing Working Capital exceeds $600,000,000, Spinco shall, within 10 Business Days after the Statement becomes final and binding on the parties, pay to Weyerhaeuser the amount by which Closing Working Capital exceeds $600,000,000. Any payment made pursuant to this Section 2.04(c) shall be made by wire transfer in immediately available funds to one or more accounts designated in writing at least two business days prior to such payment by the party entitled to receive such payment together with interest thereon at a rate of interest per annum equal to the rate of interest from time to time announced publicly by JPMorgan Chase Bank as its prime rate, calculated on the basis of the actual number of days elapsed divided by 365, from the Closing Date to the date of payment.

(d) Working Capital. The term “Working Capital” means Current Assets minus Current Liabilities. The terms “Current Assets” and “Current Liabilities” mean the current assets and current liabilities, respectively, of the portion of the Newco Business, calculated in the same way, using the same methods, policies, principles and methodologies, as the line items on the Interim Newco Balance Sheet, subject to adjustment in accordance with the Working Capital Principles. Closing Working Capital shall include the Shared Payment Amount. Without limiting the generality of the foregoing, Closing Working Capital is to be calculated (i) using the methods, policies, principles and methodologies set forth on Schedule 2.04(d), whether or not doing so is in accordance with (A) the methods used for calculating Working Capital on the Interim Newco Balance Sheet or (B) GAAP, (ii) if Schedule 2.04(d) does not set forth relevant

methods, policies, principles and methodologies, the Closing Working Capital is to be calculated in the same way, using the same methods, policies, principles and methodologies, as were used by Weyerhaeuser in preparation of the Interim Newco Balance Sheet, whether or not doing so is in accordance with GAAP, and (iii) if no relevant methods, policies, principles and methodologies are available pursuant to the foregoing clauses (i) and (ii), the Closing Working Capital is to be calculated in accordance with GAAP applied in a manner consistent with Weyerhaeuser’s historic methods, policies, principles and methodologies excluding any effects of the transactions contemplated by this Agreement. The foregoing principles are referred to in this Agreement as the “Working Capital Principles”. Closing Working Capital is to be calculated as of close of business on the day prior to the Closing Date in accordance with the Working Capital Principles. The scope of the disputes to be resolved by the Accounting Firm as provided in Section 2.04(b) shall be solely limited to whether such calculation was done in accordance with the Working Capital Principles, and whether there were mathematical errors in the Statement. Under no circumstances shall the Accounting Firm be authorized or permitted to make any other determination or adjustment based on GAAP if Working Capital Principles can be determined pursuant to clauses (i) and (ii) of the definition thereof. For purposes of this Section 2.04(d), any items on or omissions from the Interim Newco Balance Sheet that are based upon errors of fact or mathematical errors or that are not in accordance with GAAP shall be retained for purposes of calculating Closing Working Capital. Without limiting the generality of the foregoing, the Accounting Firm is not authorized or permitted to make any determination as to the accuracy of any representation or warranty in this Agreement or as to compliance by Weyerhaeuser with any of its covenants in this Agreement (other than in this Section 2.04).

(e) Post-Closing Books and Records. Following the Closing Date, neither Spinco nor Weyerhaeuser shall take any actions with respect to the accounting books and records of the Business on which the Statement is to be based that would affect the Statement. During the period of time from and after the Closing Date through the resolution of any payment contemplated by Section 2.04(c) or 2.04(f), each of Spinco and Weyerhaeuser shall afford to each other and their respective accountants and counsel in connection with any actions contemplated by this Section 2.04 reasonable access during normal business hours to all the properties, books, contracts, personnel and records of such party relevant to the Statement, the Notice of Disagreement and any payments contemplated by this Section 2.04.

(f) Shared Payment Amount. On the day that Weyerhaeuser delivers to Spinco the Statement in accordance with Section 2.04(a), Weyerhaeuser shall pay to Spinco an amount equal to (1)(A) the sum of the amount of Shared Accounts Receivable and the amount of Shared Inventory, in each case as reflected on the Statement, minus (B) the amount of the Shared Accounts Payable as reflected on the Statement (the amount so calculated, the “Shared Payment Amount”), plus (2) an amount (the “Pulp Inventory Adjustment Amount”) equal to 100% of the sum of (A) the LIFO reserve applicable to the Shared Inventory reflected on the Statement (the “LIFO Reserve Amount”) and (B) an amount equal to 5% multiplied by the sum of the Shared Inventory, as reflected in the Statement, and the LIFO Reserve Amount. On the day that the Statement becomes final

in accordance with Section 2.04(b), (i) if the Statement (as revised in accordance with Section 2.04(b)) reflects an increase in the Shared Payment Amount or the Pulp Inventory Adjustment Amount, Weyerhaeuser shall pay to Spinco the amount of such increase, and (ii) if the Statement (as revised in accordance with Section 2.04(b)) reflects a decrease in the Shared Payment Amount or the Pulp Inventory Adjustment Amount, Spinco shall pay to Weyerhaeuser the amount of such decrease. Any payment made pursuant to this Section 2.04(f) shall be made by wire transfer in immediately available funds to one or more accounts designated in writing at least two Business Days prior to such payment by the party entitled to receive such payment together. The payment pursuant to this Section 2.04(f) shall be independent of whether a payment is due pursuant to Section 2.04(c). Immediately following the Effective Time, (i) Newco shall transfer and assign to Weyerhaeuser the Shared Inventory and the Shared Accounts Receivable, and (ii) Weyerhaeuser shall assume from Newco the Shared Accounts Receivable. At such time, Newco and Spinco shall have no further rights with respect to the Shared Accounts Receivable and the Shared Inventory (which will become Excluded Assets) and shall have no further obligations with respect to the Shared Accounts Payable (which will become Retained Liabilities) other than the right to receive the payments provided for in this Section 2.04(f). Notwithstanding anything to the contrary in the Transaction Documents, Weyerhaeuser shall at any time control the collection of the Shared Accounts Receivables and the sale of the Shared Inventory and Newco and Spinco shall have no rights to dispute at any time any actions or omissions by Weyerhaeuser in connection therewith.

(g) Allocations and Payments to the Weyerhaeuser Subsidiary. All payments provided for in this Section 2.04, shall be allocated among Weyerhaeuser, Weyerhaeuser Canada and Weyerhaeuser Saskatchewan according to the respective amounts of Working Capital, Shared Accounts Receivable, Shared Accounts Payable and Shared Inventory attributable to each of them as determined by Weyerhaeuser. At Weyerhaeuser’s direction, such payments may be made to or by Weyerhaeuser, Weyerhaeuser Canada or Weyerhaeuser Saskatchewan. Any payments allocable to Weyerhaeuser Canada or Weyerhaeuser Saskatchewan which are received or made by Weyerhaeuser shall be received or made as agent for Weyerhaeuser Canada or, as applicable, Weyerhaeuser Saskatchewan and shall promptly be remitted by Weyerhaeuser to Weyerhaeuser Canada or, as applicable, Weyerhaeuser Saskatchewan (or paid by Weyerhaeuser Canada or, as applicable, Weyerhaeuser Saskatchewan to Weyerhaeuser).

(b) If the transfer, assignment or assumption of any Delayed Transfer Asset or any Delayed Transfer Liability intended to be transferred, assigned or assumed hereunder is not consummated prior to or at the Contribution Date then the member of the Weyerhaeuser Group retaining such Delayed Transfer Asset or such Delayed Transfer Liability shall thereafter hold such Delayed Transfer Asset or such Delayed Transfer Liability for the use and benefit, insofar as reasonably practicable, of Newco (at the expense of Newco). In addition, the member of the Weyerhaeuser Group retaining such Delayed Transfer Asset or such Delayed Transfer Liability shall take such other actions in order to place Newco, insofar as reasonably practicable, in the same position as if such Delayed Transfer Asset or such Delayed Transfer Liability had been transferred or assumed as contemplated hereby and so that all the benefits and burdens relating to such Delayed Transfer Asset or such Delayed Transfer Liability, including possession, use, risk of loss, potential for gain, and dominion, control and command over such asset, are to inure from and after the Contribution Date to Newco. To the extent permitted by law and to the extent otherwise permissible in light of any Legal Impediment or required Consent and/or Governmental Approval, Newco shall be entitled to, and shall be responsible for, the management and the benefits and burdens of any Delayed Transfer Asset or any Delayed Transfer Liability not yet transferred to or assumed by it as a result of this Section 2.09(b) and the parties hereto agree to use reasonable best efforts to cooperate and coordinate with respect thereto.

Any member of the Spinco Group holding an Excluded Asset or a Retained Liability improperly transferred to or assumed by the Spinco Group shall not be obligated, in connection with the foregoing, to expend any money unless the necessary funds are advanced by Weyerhaeuser, other than reasonable out-of-pocket expenses, attorneys’ fees and recording or similar fees, all of which shall be promptly reimbursed by Weyerhaeuser.

SECTION 4.06. Indemnification Procedures. (a) Procedures Relating to Indemnification of Third Party Claims. If any party (the “Indemnified Party”) receives written notice of the commencement of any action or proceeding or the assertion of any claim by a third party or the imposition of any penalty or assessment for which indemnity may be sought under Section 4.02, 4.03, 4.04 or 4.05 (a “Third Party Claim”), and such Indemnified Party intends to seek indemnity pursuant to this Article IV, the Indemnified Party shall promptly provide the other party (the “Indemnifying Party”) with written notice of such Third Party Claim, stating the nature, basis and the amount thereof, to the extent known, along with copies of the relevant documents evidencing such Third Party Claim and the basis for indemnification sought. Failure of the Indemnified Party to give such notice will not relieve the Indemnifying Party from liability on account of this indemnification, except if and to the extent that the Indemnifying Party is materially prejudiced thereby. The Indemnifying Party will have 30 days from receipt of any such notice of a Third Party Claim to give notice to assume the defense thereof. If notice to the effect set forth in the immediately preceding sentence is given by the Indemnifying Party, the Indemnifying Party will have the right to assume the defense of the Indemnified Party against the Third Party Claim with counsel of its choice; provided, however, that such counsel is reasonably satisfactory to the Indemnified Party; provided, further, however, that in the event the Indemnifying Party assumes the defense of any Third Party Claim it shall actively pursue such defense in good faith. If the Indemnifying Party does not assume the defense of such Third Party Claim within 30 days of receipt of such notice, the Indemnified Party against which such Third Party Claim has been asserted will have the right to assume the defense thereof, at its sole cost and expense, upon delivery of notice to such effect to the Indemnifying Party; provided, however, that if the Indemnifying Party at any time thereafter agrees to assume the defense of such Third Party Claim, the Indemnifying Party shall bear the reasonable fees, costs and expenses of the Indemnified Party’s counsel incurred prior to the time of the Indemnifying Party’s assumption of such defense. So long as the Indemnifying Party has assumed the defense of the Third Party Claim in accordance herewith, (i) the Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third Party Claim, (ii) the Indemnified Party will not file any papers or consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party and (iii) the Indemnifying Party will not (A) admit to any wrongdoing or (B) consent to the entry of

any judgment or enter into any settlement with respect to the Third Party Claim to the extent such judgment or settlement provides for (x) relief other than money damages or (y) money damages if the Indemnifying Party has not acknowledged in writing that it shall be responsible for such money damages, in each case, without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed). The parties will use their reasonable best efforts to minimize Losses from Third Party Claims and will act in good faith in responding to, defending against, settling or otherwise dealing with such claims. The parties will also cooperate in any such defense and give each other reasonable access to all information relevant thereto. Whether or not the Indemnifying Party has assumed the defense, such Indemnifying Party will not be obligated to indemnify the Indemnified Party hereunder for any settlement entered into or any judgment that was consented to without the Indemnifying Party’s prior written consent.

(b) Procedures for Non-Third Party Claims. The Indemnified Party will notify the Indemnifying Party in writing promptly of its discovery of any matter that does not involve a Third Party Claim giving rise to the claim of indemnity pursuant hereto. The failure so to notify the Indemnifying Party shall not relieve the Indemnifying Party from liability on account of this indemnification, except only to the extent that the Indemnifying Party is materially prejudiced thereby. The Indemnifying Party will have 30 days from receipt of any such notice to give notice of dispute of the claim to the Indemnified Party. The Indemnified Party will reasonably cooperate and assist the Indemnifying Party in determining the validity of any claim for indemnity by the Indemnified Party and in otherwise resolving such matters. Such assistance and cooperation will include providing reasonable access to and copies of information, records and documents relating to such matters, furnishing employees to assist in the investigation, defense and resolution of such matters and providing legal and business assistance with respect to such matters.

SECTION 4.07. Indemnification as Sole and Exclusive Remedy. Subject to Section 4.09(a), Weyerhaeuser, Spinco and Newco acknowledge and agree that, should the Distribution occur, Weyerhaeuser’s, Weyerhaeuser Canada’s, Weyerhaeuser Saskatchewan’s, Spinco’s, Newco’s, Newco Canada Exchangeco’s and Exchangeco Subsidiary’s sole and exclusive remedy with respect to any and all claims relating to this Agreement, the Newco Business, the Newco Assets, the Excluded Assets, the Newco Liabilities, the Retained Liabilities, the Newco Canada Exchangeco Assets, the Canadian Excluded Assets, the Newco Canada Exchangeco Liabilities, the Canadian Retained Liabilities or the transactions contemplated by this Agreement and the Ancillary Agreements shall be pursuant to the indemnification provisions set forth in this Article IV. In furtherance of the foregoing and subject to the indemnification provision set forth in this Article IV, Weyerhaeuser, Spinco and Newco hereby waive, from and after the Distribution Date, any and all rights, claims and causes of action Weyerhaeuser or any other Weyerhaeuser Indemnitee, on the one hand, and Spinco or any other Spinco Indemnitee, on the other hand, may have against Spinco or any of its affiliates or, respectively, Weyerhaeuser or any of its affiliates, or their respective directors, officers and employees arising under or based upon any Federal, state, provincial, local or foreign statute, law, ordinance, rule or regulation or otherwise (including with respect to

environmental matters generally and any matters under the Comprehensive Environmental Response, Compensation, and Liability Act). This Section 4.07 will not apply to any breach following the Effective Time of the Transaction Agreement, the Tax Sharing Agreement, the Intellectual Property License Agreement, the Site Services Agreements, the Fiber Supply Agreements and the Transition Services Agreement.

SECTION 4.08. Calculation of Indemnity Payments. The amount of any Loss for which indemnification is provided under this Article IV shall be net of any amounts recovered by the Indemnified Party under insurance policies or underground storage tank reimbursement programs, with respect to such Loss and shall be (a) increased to take account of any net Tax cost actually incurred by the Indemnified Party arising from the receipt of indemnity payments hereunder (grossed up for such increase) and (b) reduced to take account of any net Tax benefit actually realized by the Indemnified Party arising from the incurrence or payment of any such indemnified amount. In computing the amount of any such Tax cost or Tax benefit, the Indemnified Party shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the receipt of any indemnity payment hereunder or the incurrence or payment of any indemnified amount. For purposes of indemnification under Sections 4.02 and 4.04, the amount of any Loss shall be reduced to the extent of any related “current liability” in the Statement (as fully resolved).

SECTION 4.09. Additional Matters. (a) Notwithstanding anything to the contrary in this Agreement, indemnification for Tax matters shall be governed by the terms, provisions and procedures of the Tax Sharing Agreement and not by this Article IV.

(b) In no event shall an Indemnifying Party be liable for special, punitive, exemplary, incidental, consequential or indirect damages, or lost profits, whether based on contract, tort, strict liability, other law or otherwise other than in the case of Third Party Claims.

ARTICLE V

(a) Weyerhaeuser shall, and shall cause its subsidiaries to, keep all insurance policies currently maintained with respect to the Newco Assets, the Newco Canada Exchangeco Assets and the Newco Business (the “Weyerhaeuser Insurance Policies”), or suitable replacements therefor, in full force and effect through the close of business on the Distribution Date. Spinco and Newco acknowledge that any and all Weyerhaeuser Insurance Policies are owned and maintained by Weyerhaeuser or any member of the Weyerhaeuser Group (and not the Newco Business) and are Excluded Assets. Subject to Section 6.01(b), Spinco and Newco will not have any rights under the Weyerhaeuser Insurance Policies from and after the Distribution Date.

(b) If any Newco Asset, any Newco Canada Exchangeco Asset or the Newco Business suffers or has suffered any damage, destruction or other casualty loss or any Assumed Liability or Newco Canada Exchangeco Liability that is insured under the Weyerhaeuser Insurance Policies and arises or has arisen prior to the Distribution Date (but, in the case a loss arising from damage, destruction or other casualty loss to any Newco Asset or any Newco Canada Exchangeco Asset, after March 25, 2006), Weyerhaeuser shall, or shall cause the appropriate member of the Weyerhaeuser Group to, (i) assert a claim under the appropriate Weyerhaeuser Insurance Policies, and (ii) (x) surrender to Newco after the Distribution Date any insurance proceeds received by Weyerhaeuser or any member of the Weyerhaeuser Group under any Weyerhaeuser Insurance Policy with respect to such damage, destruction, liability or loss, less any amount of cash or proceeds applied by Weyerhaeuser or any other member of the Weyerhaeuser Group to the physical restoration of such asset or payment of such liability, and (y) assign to Newco after the Distribution Date all rights of Weyerhaeuser or any member of the Weyerhaeuser Group with respect to any causes of action (other than the rights with respect to causes of actions under the Weyerhaeuser Insurance Policies, which are hereby expressly retained by Weyerhaeuser), whether or not litigation has commenced as of the Distribution Date, in connection with such damage, destruction, liability or loss; provided, however, that the amount of the insurance proceeds to be surrendered to Newco shall be reduced by the amount of any applicable deductibles and co-payment provisions or any payment, reinsurance or reimbursement obligations of Weyerhaeuser or any member of the Weyerhaeuser Group in respect thereof. During three years after the Distribution Date (or, if later, until the final resolution of any relevant claim relating to the Newco Business), Weyerhaeuser shall not and shall cause the other members of the Weyerhaeuser Group not to amend, terminate, buy-out, extinguish or otherwise modify its or their respective liability under any Weyerhaeuser

Insurance Policies in a manner that would adversely affect Newco’s rights pursuant to this Section 6.01(b); provided, however, that this sentence shall not require Weyerhaeuser to renew or keep from lapsing any Weyerhaeuser Insurance Policy.

SECTION 6.02. Registration Prior to the Distribution Date. (a) If required by applicable law, the parties shall use their reasonable best efforts to prepare and file with the Commission a registration statement under the Securities Act and each party shall use its reasonable best efforts to have such registration statement declared effective by the Commission as promptly as practicable after such filing and to keep such registration statement effective as long as necessary to consummate the Distribution. The parties shall use their reasonable best efforts to prepare and file with the Commission any necessary amendment or supplement to such registration statement.

(b) The parties hereto shall take all such actions as may reasonably be required or appropriate under federal or state securities or Blue Sky laws (and any comparable laws under any foreign jurisdiction) in connection with the transactions contemplated by this Agreement or any Ancillary Agreement.

(c) The parties shall cooperate in preparing, filing with the Commission and causing to become effective any registration statements or amendments thereto, if any, which are necessary or appropriate to reflect the establishment of, or amendments to, any employee benefit plans contemplated by Sections 6.08 and 6.09 of the Transaction Agreement requiring registration under the Securities Act.

SECTION 6.03. Financing Arrangements. Prior to the Distribution, Spinco shall enter into an agreement or agreements providing for the New Debt Amount. Weyerhaeuser, Spinco and Newco shall participate in the preparation of all materials and presentations as may be reasonably necessary to secure funding pursuant to such agreement or agreements, including rating agency presentations necessary to obtain the requisite ratings needed to secure the Transaction Debt. Notwithstanding anything to the contrary in this Agreement or any other Transaction Document, Spinco and Newco, jointly and severally, shall pay all third party costs and expenses incurred by any member of the Weyerhaeuser Group associated with the Transaction Debt.

SECTION 6.04. Enforcement of Confidentiality Agreements. Weyerhaeuser shall not, and shall not permit any other member of the Weyerhaeuser Group to, waive or amend any confidentiality agreement between Weyerhaeuser or any other member of the Weyerhaeuser Group and any Person (other than any member of the Weyerhaeuser Group) to the extent such waiver or amendment adversely affects the confidentiality of information related to the Newco Business. At Spinco’s written request, Weyerhaeuser shall, and shall cause each other member of the Weyerhaeuser Group to, enforce in accordance with its terms any confidentiality agreement between Weyerhaeuser or any other member of the Weyerhaeuser Group and any Person (other than any member of the Weyerhaeuser Group) to the extent such agreement protects the confidentiality of information related to the Newco Business; provided, however, that no member of the Weyerhaeuser Group shall be obligated to expend any money in connection with this Section 6.04 unless the necessary funds are advanced by Spinco,

other than reasonable out-of-pocket expenses, which shall be promptly reimbursed by Spinco.

SECTION 6.05. Site Separation Requirements. The parties acknowledge and agree that the Newco Business includes only portions of the operations conducted at the Weyerhaeuser facilities located in Plymouth, North Carolina; Kamloops, British Columbia and Columbus, Mississippi. Weyerhaeuser will use reasonable best efforts to (i) secure any Governmental Approvals required for separation of these operations from the other operations conducted at these facilities as set forth on Schedule 6.05, subject to such modifications as may be required or requested by Governmental Entities, and (ii) accomplish the subdivision, in accordance with the Governmental Approvals, so as to be able to convey the fee interests in such subdivided portions to Newco. In addition, with respect to each such portion, the subdivision of which shall have been accomplished by the Contribution Date, to the extent that Schedule 6.05 provides for easements and/or operating agreements to be entered into in connection with the separation of the operations described in this Section 6.05, Weyerhaeuser or the applicable member(s) of the Weyerhaeuser Group and Newco will execute and deliver such agreements on the Contribution Date. Notwithstanding the foregoing, to the extent that Weyerhaeuser has not accomplished the subdivision required for the conveyance of fee interests in the applicable portions of one or more of these facilities to Newco on the Contribution Date, (a) Weyerhaeuser or the applicable member(s) of the Weyerhaeuser Group and Newco, on the Contribution Date, will enter into interim net leases, under the terms set forth in Schedule 6.05, leasing to Newco the applicable portions of each of such facilities for which the subdivision has not been accomplished by the Contribution Date, pending the obtaining of such Governmental Approvals, it being the parties’ intent that the conveyance of the fee interest of the premises demised under each of such leases to Newco (with such modifications as may be required by the Governmental Entities in granting such Governmental Approvals) shall occur promptly after the accomplishment of the applicable subdivision, and (b) to the extent that Schedule 6.05 provides for easements and/or operating agreements to be entered into in connection with the separation of the operations at such facilities, Weyerhaeuser or the applicable member(s) of the Weyerhaeuser Group and Newco shall, in lieu of causing such agreements to be executed and delivered on the Contribution Date, arrange for the easements and/or services to be provided to Newco on an interim basis under the Transition Services Agreement or otherwise pending conveyance of fee interests in the premises demised under such leases to Newco, until the conveyance of such fee interests. Newco will cooperate with Weyerhaeuser in connection with the separation of the operations at the facilities and Weyerhaeuser’s efforts to secure the Governmental Approvals described in this Section 6.05.

ARTICLE VII

Additional Covenants

SECTION 7.01. Agreement for Exchange of Information; Archives. (a) Following the Distribution Date, for so long as such information is retained by a party or any of its subsidiaries (which shall be for a period of at least seven years for all records necessary in connection with Taxes and in resolving all disputes and audits with respect to all taxable periods relating to Taxes and shall be a period of at least four years for information relating to all other matters), upon

reasonable written notice, each party shall afford or cause to be afforded to the other party and its agents, representatives and auditors reasonable access to the personnel, properties, books, systems, Contracts, and Records (including financial records) relating to the Newco Business for any reasonable business purpose, including in respect of litigation, insurance matters and financial reporting of such party and its affiliates, including by, as and when reasonably requested by the other party, providing copies of any the foregoing books, systems, Contracts and Records (including financial records) related to the Newco Business to the other party; provided, that the party requesting such access agrees to reimburse the other party promptly for all reasonable and necessary out-of-pocket costs and expenses incurred in connection with any such request. Notwithstanding the foregoing, a party will not be required to disclose any information (i) which such party is prohibited from disclosing by a confidentiality agreement with a third party if such party has used reasonable best efforts to obtain the consent of the third party to such disclosure (it being understood that no party shall be obligated to pay any consideration to any third party from whom such consent is requested), or (ii) which would constitute privileged attorney-client communications or attorney work product, the transfer of which or the provision of access to which would, as reasonably determined by such party’s counsel, constitute a waiver of any such privilege. If any material is withheld by a party pursuant to the immediately preceding sentence, such party shall inform the other party as to the general nature of what is being withheld. Weyerhaeuser may redact such portions of any books and records (including any Records and Transferred Records) that do not relate to the Newco Assets, the Newco Canada Exchangeco Assets, the Newco Liabilities, the Newco Canada Exchangeco Liabilities or the Newco Business.

(b) After the Distribution Date, except in the case of an Action by one party against another party, each party hereto shall use its reasonable best efforts to make available to each other party, upon written request, the former, current and future directors, officers, employees, other personnel and agents of members of the Newco Business as witnesses, to the extent that any such Person (giving consideration to business demands of such directors, officers, employees, other personnel and agents) may reasonably be required in connection with any Action in which the requesting party may from time to time be involved, regardless of whether such Action is a matter with respect to which indemnification may be sought hereunder. The requesting party shall bear all costs and expenses in connection therewith.

SECTION 7.02. Further Assurances. From time to time, as and when requested by any party, each party shall execute and deliver, or cause to be executed and delivered, all such documents and instruments and shall take, or cause to be taken, all such further or other actions, as such other party may reasonably deem necessary or desirable to consummate the transactions contemplated by this Agreement and the Ancillary Agreements.

SECTION 7.03. No Use of Certain Retained Names. Newco shall, and shall cause its subsidiaries to, promptly, and in any event (a) within 60 days after the Distribution Date, make all necessary filings and take all other necessary actions to discontinue any references to the Retained Names, (b) within 180 days after the

Distribution Date, to revise print advertising, product labeling and all other information or other materials, including any Internet or other electronic communications vehicles, to delete all references to the Retained Names and (c) within 180 days after the Distribution Date, to change signage and stationery and otherwise discontinue use of the Retained Names. In no event shall Newco or any of its subsidiaries use any Retained Names after the Distribution in any manner or for any purpose different from the use of such Retained Names by Weyerhaeuser or any of its subsidiaries during the 90-day period preceding the Distribution Date. With respect to the Transferred Inventory, Newco may continue to sell such inventory, notwithstanding that it or its labeling or packaging bears one or more of the Retained Names, for 12 months after the Distribution. None of the foregoing provisions of this Section 7.03 shall be construed to obligate Newco to require any wholesaler, retailer or other merchant or customers of the Newco Business to conduct themselves in accordance therewith. After the Distribution Date, Newco shall file applications to amend or terminate any certificate of assumed name or d/b/a filings, within 60 days after Newco shall have become aware of such assumed name or d/b/a filing so as to eliminate the right of Newco to use the Retained Names.

SECTION 7.04. Permits. Weyerhaeuser, Spinco and Newco shall use their reasonable best efforts to obtain, or to cause to be obtained, a Permit for Newco or Exchangeco Subsidiary with respect to each Permit currently used by Weyerhaeuser, Weyerhaeuser Canada or Weyerhaeuser Saskatchewan in connection with the operation of, the Newco Business that is not transferred pursuant to Section 2.02(a)(vii) or pursuant to the Canadian Purchase Agreement; provided, however, that Weyerhaeuser shall not be obligated to pay any consideration to any third party or Governmental Entity from whom such Permits are requested under this Section 7.04.

SECTION 7.05. Removal of Certain Property. If the containerboard machine (and related old corrugated container assets) set forth on Schedule 2.02(b)(i) have not been removed from the facility located in Plymouth, North Carolina, prior to the Distribution Date, Newco shall allow Weyerhaeuser to have reasonable access to such facility after the Distribution Date for the purpose of removing such machine and related assets. Weyerhaeuser shall bear all costs of such removal and shall reimburse Newco for the reasonable costs of repairing any damage to the facility caused by such removal and shall reimburse Newco for any other reasonable expenses Newco may incur in connection with such removal (including the reasonable cost of any work stoppage at such facility caused by such removal). Weyerhaeuser shall complete the asset removals provided under this Section 7.05 within one year of the Distribution Date.

SECTION 7.06. Covenant Not to Compete. (a) In consideration of the mutual covenants provided for in this Agreement and the other Transaction Documents and other good and valuable consideration to be delivered to Weyerhaeuser and its shareholders in connection with the transactions contemplated hereby or thereby (the sufficiency of which is hereby acknowledged), during the period beginning on the Distribution Date and ending on the third year anniversary of the Distribution Date, Weyerhaeuser shall not, and shall cause each of its subsidiaries not to, directly or indirectly, engage in activities or businesses, or establish any new businesses, within North America that are substantially in competition with the uncoated free sheet

operations (including uncoated free sheet converting operations) and the forms operations included in the Newco Business as conducted on the Distribution Date (“Competitive Activities”); provided, however, that:

(i) this Section 7.06(a) shall be deemed not breached as a result of the ownership by Weyerhaeuser or any of its subsidiaries of: (A) any other securities (other than 20% or more of stock having general voting power in the election of directors (or securities exchangeable for such stock)) of a Person (other than a subsidiary of Weyerhaeuser) engaged, directly or indirectly, in Competitive Activities; or (B) any securities of a Person (other than a subsidiary of Weyerhaeuser) that engages, directly or indirectly, in Competitive Activities if, at the time such securities are acquired, such Competitive Activities account for less than 10% of such Person’s consolidated annual revenues;

(ii) nothing contained in this Section 7.06(a) shall prohibit or restrict (A) activities or businesses of Weyerhaeuser or any of its subsidiaries related to the Excluded Assets, (B) the sale of goods and services produced by or related to the Excluded Assets, or (C) subject to Section 7.06(a)(i), any restructuring or sale of any of the Excluded Assets; and

(iii) nothing contained in this Section 7.06(a) shall prohibit or restrict Weyerhaeuser or any of its subsidiaries from being acquired after the Distribution Date by a non-affiliated third Person which prior to such acquisition conducted Competitive Activities in North America.

(b) The parties agree that the covenants included in this Section 7.06 are, taken as a whole, reasonable in their geographic and temporal coverage, and no party shall raise any issue of geographic or temporal reasonableness in any proceeding to enforce such covenant; provided, however, that if the provisions of this Section 7.06 should ever be deemed to exceed the time or geographic limitations or any other limitations permitted by applicable Law in any jurisdiction, then such provisions shall be deemed reformed in such jurisdiction to the minimum extent required by applicable Law to cure such problem.

(c) The parties acknowledge and agree that in the event of a breach of the provisions of this Section 7.06, monetary damages shall not constitute a sufficient remedy. Consequently, in the event of any such breach, the non-breaching party may, in addition to any other rights and remedies existing in its favor, apply to any court referred to in Section 9.09 for specific performance and/or preliminary and final injunctive relief or other relief to enforce or prevent any violation of the provisions hereof.

SECTION 7.07. Cooperation with respect to Quarterly Reports. Following the Distribution Date, Weyerhaeuser shall cooperate, and shall request its independent accountants to cooperate, with Spinco in providing information for the preparation of any reports that are required to be filed by Spinco with the SEC pursuant to Section 13 or 15(d) of the Exchange Act with respect to any fiscal quarter up to and including the fourth complete fiscal quarter following the Distribution Date.

Notwithstanding anything to the contrary in the Transaction Documents, Spinco shall pay all fees and expenses of Weyerhaeuser’s independent accountants and Weyerhaeuser’s reasonable expenses in connection with the preparation of such reports. Spinco and Newco, jointly and severally, shall indemnify, defend and hold harmless Weyerhaeuser from and against any and all Losses, under the Exchange Act or otherwise, in connection with such quarterly reports except to the extent arising or resulting from information provided by Weyerhaeuser for inclusion in such reports that is inaccurate or incomplete in any material respect.

SECTION 7.08. Canadian Asset Sale Structure. The parties shall use reasonable best efforts to cause the Canadian Asset Sale to be structured in the most mutually Tax-efficient manner; provided, however, that no party will be required to agree to a structure that would reasonably be expected to increase costs, expenses or liabilities expected to be incurred by such party in connection with the transactions contemplated by the Transaction Documents.

EXCEPT AS MAY EXPRESSLY BE SET FORTH IN THIS AGREEMENT, THE CONTRIBUTION AND DISTRIBUTION AGREEMENT OR ANY ANCILLARY AGREEMENT, (A) LICENSOR MAKES NO REPRESENTATION OR WARRANTY OF ANY KIND WHATSOEVER, EXPRESS OR IMPLIED, WITH RESPECT TO THE LICENSE OF ANY RETAINED LICENSED INTELLECTUAL PROPERTY, (B) ALL OF THE RETAINED LICENSED INTELLECTUAL PROPERTY TO BE LICENSED IN ACCORDANCE WITH THIS AGREEMENT, THE CONTRIBUTION AND DISTRIBUTION AGREEMENT OR ANY ANCILLARY AGREEMENT SHALL BE LICENSED ON AN “AS IS, WHERE IS” BASIS, AND ALL IMPLIED WARRANTIES AS TO THE VALIDITY OR NON-INFRINGEMENT OF THE RETAINED LICENSED INTELLECTUAL PROPERTY AND AS TO THE ADEQUACY OF THE RETAINED LICENSED INTELLECTUAL PROPERTY FOR THEIR PURPOSE ARE HEREBY EXPRESSLY DISCLAIMED, AND (C) NONE OF THE PARTIES HERETO OR ANY OTHER PERSON MAKES ANY REPRESENTATION OR WARRANTY WITH RESPECT TO ANY INFORMATION, DOCUMENTS OR MATERIAL MADE AVAILABLE IN CONNECTION WITH THE ENTERING INTO OF THIS AGREEMENT, THE CONTRIBUTION AND DISTRIBUTION AGREEMENT, ANCILLARY AGREEMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

SECTION 7. Registration and Maintenance. (a) Licensor and Licensee will use commercially reasonable efforts to protect the Retained Licensed Technology as trade secrets. Licensor will use commercially reasonable efforts to maintain the Retained Licensed Patents and the Retained Licensed Copyrights (collectively, the “Registerable Intellectual Property”) and all registrations thereof and/or applications therefor. Licensee will execute all documents as are reasonably necessary or expedient to aid in, and will otherwise cooperate at Licensor’s expense with, Licensor’s efforts to prepare, obtain, file, record and maintain all such registrations and applications. (b) To the extent Licensor has not registered any Registerable Intellectual Property, Licensee may, at its own expense, register such Registerable Intellectual Property, in the name of, and on behalf of, Licensor provided that (x) Licensee gives written notice of its intention to register such Registerable Intellectual Property, and (y) within 30 days of such notice, (i) Licensor does not object to Licensee registering such Registerable Intellectual Property or (ii)

B-3

Licensor fails to register such Registerable Intellectual Property. (c) To the extent Licensor has not maintained or does not intend to maintain any registrations or applications for Registerable Intellectual Property, Licensee may, at its own expense, make such filings as are necessary to maintain any registrations or applications therefor, in the name of, and on behalf of, Licensor. Licensor will give notice to Licensee as soon as it decides not to maintain any such registrations or applications but in any event not less than 60 days before such filings are due.

SECTION 8. Infringement Actions.

(a) Licensor will from time to time take all steps that it considers (in its sole discretion) necessary to protect Licensor’s and Licensee’s rights in and to the Retained Licensed Intellectual Property (other than the Solaia Patents and the Lemelson Patents), and Licensee agrees forthwith to communicate to Licensor any infringements or misappropriations or threatened infringements or misappropriations of any such rights of Licensor which may come to its notice and, at Licensor’s expense, to do all and any such acts as Licensor may reasonably require for preventing such infringements or misappropriations or threatened infringements or misappropriations. In the event Licensor takes affirmative action against an infringement or misappropriation, Licensee agrees to assist Licensor in whatever manner Licensor reasonably requests, at the expense of Licensor. Recovery of damages resulting from any such action shall be solely for the account of Licensor. Licensee will provide information reasonably requested by Licensor in any infringement or misappropriation action, including in connection with the calculation of damages. Licensee may participate, at its expense, in any action taken by or proceeding instituted by or brought against Licensor through separate counsel of Licensee’s own choosing; provided that Licensor will at all times retain full control over such action.

(b) Licensor will use reasonable efforts to enforce Licensor’s contractual or other confidentiality rights against an individual employee to the extent that such rights relate to an unauthorized disclosure or use of Retained Licensed Technology after the individual has left the employment of Licensor. If, in the case of such an unauthorized disclosure or use of any Retained Licensed Technology by an individual who becomes a former employee of Licensor, Licensee (a) determines to take action against such an individual, whether by commencing a proceeding or otherwise, and (b) requests that Licensor join such action by enforcing Licensor’s rights against such individual, Licensor will enforce such rights and otherwise provide reasonable cooperation to Licensee.

(c) Notwithstanding any limitations on Licensee’s rights to use any of the Retained Licensed Intellectual Property pursuant to Section 2, if (i) a third party is, in the reasonable opinion of Licensee, infringing or misappropriating any of such Retained Licensed Intellectual Property (other than the Solaia Patents and the Lemelson Patents) in a manner that is material to the Newco Business, (ii) Licensee notifies Licensor of such third party activities in accordance with Section 12, and (iii) Licensor does not take affirmative action either to prevent such activities or subject to Section 22, to license to such third party under the Retained Licensed Intellectual Property (other than the Solaia Patents and the Lemelson Patents) required for such

B-4

activities, then Licensee’s ability to use such Retained Licensed Intellectual Property (other than the Solaia Patents and the Lemelson Patents) is no longer subject to the restrictions set forth in Section 2 on the use of such Retained Licensed Intellectual Property (other than the Solaia Patents and the Lemelson Patents).

SECTION 9. Indemnification.

(a) Each party (the “Indemnifying Party”) shall indemnify and hold harmless and, at the other party’s sole option, defend, the other party and its affiliates and its and their respective officers, directors, employees, agents, advisers and representatives (the “Indemnified Parties”) from and against any and all claims, demands, liabilities, obligations, taxes, losses, fines, costs, expenses, royalties, litigation, deficiencies or damages (whether absolute, accrued, conditional or otherwise resulting from third-party claims), including interest and penalties with respect thereto and out-of-pocket expenses and reasonable attorneys’ and accountants’ fees and expenses incurred in the investigation or defense of any of the same or in asserting, preserving or enforcing any of their respective rights hereunder (collectively, “Losses”), resulting from or arising out of any claims or actions of third parties based on or arising out of any breach of any representation, warranty, covenant or obligation under this Agreement.

(b) In the event that any Indemnified Party elects to have the Indemnifying Party defend any claim or action of third parties referred to in Section 9(a), (i) such Indemnified Party will so notify the Indemnifying Party in writing, (ii) such Indemnified Party shall have the right to approve the Indemnifying Party’s counsel, which approval shall not unreasonably be withheld, and to obtain its own counsel at such Indemnified Party’s own expense and (iii) the Indemnifying Party shall obtain the approval of such Indemnified Party before entering into any compromise regarding such actions that would impose any liability or obligation on such Indemnified Party, which approval will not be unreasonably withheld. In the event that such Indemnified Party elects to defend any claim or action of third parties referred to in Section 9(a), the Indemnifying Party shall pay all reasonable attorney’s fees and expenses in connection with such defense. If any claim, demand, assessment or liability, or cost incidental thereto, is asserted against an Indemnified Party in respect of which the Indemnified Party proposes to demand indemnification from the Indemnifying Party pursuant to this Section 9, such Indemnified Party will promptly notify the Indemnifying Party in writing. No failure of an Indemnified Party to promptly notify the Indemnifying Party shall relieve the Indemnifying Party from the obligation to indemnify the Indemnified Party unless and to the extent the Indemnifying Party is actually prejudiced by such failure.

SECTION 10. Confidentiality. Each party agrees and will undertake to keep any information regarding the Retained Licensed Intellectual Property or otherwise received under this Agreement confidential and will refrain from disclosing it to any third party, unless (and to the extent) compelled to disclose by judicial or administrative process or, in the opinion of such party’s counsel, by the requirements of applicable law or regulations (including Securities and Exchange Commission rules and regulations), in which case the party seeking to disclose such information will give the other party reasonable advance notice of such disclosure in order to permit the other party to seek an appropriate protective order or to attempt to reach mutual agreement regarding the portions of such information that should be subject to a request for confidential treatment, and except to the extent that such information (a) is required to be

B-5

disclosed by either party in order to carry out its rights or obligations hereunder, (b) is in the public domain through no fault of the party to which it is furnished, including through prior public disclosure made in accordance with this Section 10, (c) is independently developed by the party to which it is furnished without use of, reference to, or reliance upon, the furnishing party’s information, as evidenced by written documentation, or (d) is later lawfully acquired from other sources (without obligations of confidentiality) by the party hereto to which it is furnished.

SECTION 11. No Third-Party Beneficiaries. This Agreement is for the sole benefit of the parties hereto and their permitted assigns and nothing herein expressed or implied shall give or be construed to give to any person, other than the parties hereto and such assigns, any legal or equitable rights hereunder.

SECTION 14. Independent Contractors. The parties to this Agreement intend by this Agreement to enter into only a license agreement and this Agreement shall not in any way be deemed to establish any other relation between them.

Neither Licensee, on the one hand, nor Licensor, on the other hand, nor any employee, officer, director or agent of either shall hold themselves out as an agent of the other party. Nothing in this Agreement shall be construed to grant either party any right or authority to assume or create any obligation on behalf or in the name of the other; to accept summons or legal process for the other; or to bind the other in any manner whatsoever.

SECTION 15. Severability; Enforcement. The invalidity of any portion of this Agreement shall not affect the validity, force or effect of the remaining portions hereof. If it is ever held that any restriction hereunder is too broad to permit enforcement of such restriction to its fullest extent, each party agrees that a court of competent jurisdiction may enforce such restriction to the maximum extent permitted by law, and each party hereby consents and agrees that such scope may be judicially modified accordingly in any proceeding brought to enforce such restriction.

SECTION 16. Integrated Contract; Schedule.
