WHEREAS, for federal income tax purposes, the Separation is intended to qualify for tax-free treatment under Section 368(a)(1)(D) and Section 355 of the Internal Revenue Code of 1986, as amended (the “Code”) and the Distribution is intended to qualify for tax-free treatment under Section 355 of the Code; and

In asserting and pursuing such coverage and payment, and subject to Section 10.6, Potlatch shall have sole power and authority to make binding decisions, determinations, commitments and stipulations on its own behalf and on behalf of the Clearwater Group. Any amounts received by Potlatch with respect to any Administered Claim related to the Pulp-Based Business that are settled subsequent to the Distribution Date shall be paid, net of any deductibles, self-insured retentions, reserves or any combination thereof (for which Clearwater shall be liable), to Clearwater within five business days of receipt thereof by Potlatch.

(c) Consistent with past practices and subject to Section 8.6(a), following the Distribution the Clearwater Group shall assume responsibility for, and shall pay to the

appropriate insurance carriers, the Potlatch Group or otherwise, any premiums, retrospectively-rated premiums, defense costs, indemnity payments or uninsured costs arising from any liability or workers compensation losses which are uninsured because of coverage terms or conditions of the policies covering such losses, or other charges (including, but not limited to, deductibles, self-insured retentions, reserves and the like) (collectively, “Insurance Charges”) whenever occurring, which shall become due and payable under the terms and conditions of any applicable Potlatch Policy in respect of any Losses or Actions attributable to pre-Distribution occurrences related to the Pulp-Based Business, whenever becoming known, which Insurance Charges are known or become known prior to, on or after the Distribution Date. To the extent that the terms of any applicable Potlatch Policy provide that any member of the Potlatch Group shall have an obligation to pay or guarantee the payment of any such Insurance Charges, Potlatch shall be entitled to demand that Clearwater make such payment directly to the Person or entity entitled thereto. In connection with any such demand, Potlatch shall submit to Clearwater a copy of any invoice or listing of claims received by Potlatch pertaining to such Insurance Charges together with appropriate supporting documentation. In the event that Clearwater fails to pay any such Insurance Charges when due and payable, whether at the request of the Person entitled to payment or upon demand by Potlatch, the Potlatch Group may (but shall not be required to) pay such insurance charges for and on behalf of the Clearwater Group and, thereafter, Clearwater shall promptly reimburse Potlatch for such payment.

Section 8.7 Non-Waiver of Rights to Coverage; Subrogation. An insurance carrier that would otherwise be obligated to pay any claim shall not be relieved of the responsibility with respect thereto, or, solely by virtue of the provisions of this Agreement, have any subrogation rights with respect thereto. To the fullest extent permitted by law, each of the parties hereto hereby contractually waives any and all rights of insurer subrogation under all pertinent policies with respect to the matters covered by this Agreement, and shall exercise commercially reasonable efforts to ensure such waiver of subrogation with respect to each of their respective insurers and all such pertinent policies. No insurance carrier or any third party shall be entitled to a benefit (i.e., a benefit they would not be entitled to receive had no Distribution occurred or in the absence of the provisions of this Agreement) by virtue of the provisions hereof. For the avoidance of doubt, no provision of this Agreement is intended or shall be construed in any way to prejudice or limit insurance coverage under any applicable policy of insurance or reinsurance.

Section 8.8 Scope of Affected Policies of Insurance. The provisions of this Article VIII relate solely to matters involving property damage and business interruption, and liability insurance policies and programs, including, without limitation, primary and excess general liability, executive liability, automobile, workers’ compensation, property damage and business interruption, crime and surety insurance policies, and shall not be construed to affect any obligation of or impose any obligation on the Parties with respect to any life, health and accident, dental or medical or any other insurance policies applicable to any of the officers, directors, employees or other representatives of the Parties or their Affiliates.

ARTICLE IX

EXPENSES

Section 9.1 Allocation of Expenses. Except as otherwise provided in this Agreement or any other agreement contemplated hereby, (a) all fees, expenses and other costs relating to the

Separation or the Distribution that are incurred prior to the Distribution Date shall be allocated in accordance with the Parties’ allocation methodology prior to the date hereof, and (b) all fees, expenses and other costs relating to the Separation or the Distribution that are incurred after the Distribution Date shall be paid by the Party incurring such expenses. Without limiting the foregoing and for the sake of clarity, the Parties expect that all fees, expenses and other costs associated with the Credit Facility that are incurred prior to the Distribution Date shall be subject to Section 9.1(a).

ARTICLE X

INDEMNIFICATION

Section 10.1 Release of Pre-Distribution Claims.

(a) Except as provided in Section 10.1(b) and except for any matter for which any Person is entitled to indemnification or contribution pursuant to this Article X, effective as of the Distribution Date, each Party does hereby, on behalf of itself and, to the extent of its power and authority, its Subsidiaries, Affiliates and Related Persons, release and forever discharge the other Party, its Subsidiaries, Affiliates and Related Persons, from any and all Liabilities whatsoever, whether at Law or in equity (including any right of contribution), whether arising under any Contract, by operation of Law or otherwise, existing or arising from any acts or events occurring or failing to occur or alleged to have occurred or to have failed to occur or any conditions existing or alleged to have existed on or before the Distribution Date, including in connection with the transactions and all other activities to implement the Distribution.

(b) Nothing contained in Section 10.1(a) shall impair any right of any Person identified in Section 10.1(a) to enforce this Agreement, any Ancillary Agreement or any Shared Contract, in each case in accordance with its terms. Nothing contained in Section 10.1(a) shall release any Party from indemnifying any Related Person of another Party, its Subsidiaries or Affiliates, who was a Related Person of the first Party, its Subsidiaries or Affiliates on or prior to the Distribution Date and entitled to such indemnification pursuant to obligations existing prior to the Distribution Date. Nothing contained in Section 10.1(a) shall release or discharge any rights or claims that either Party, its Subsidiaries, Affiliates or its Related Person may have against any Related Person of the other Party as a result of any Knowing Violation of Law or fraud by such Related Person. Nothing contained in Section 10.1(a) shall release any Person from:

(i) any Liability that is Assumed, retained or allocated to a Party, its Subsidiaries or Affiliates in accordance with this Agreement or any Ancillary Agreement;

(ii) any Liability for the sale, lease or receipt of goods, property or services purchased, obtained or used in the ordinary course of business by a member of one Group or its Related Persons from a member of the other Group or its Related Persons prior to the Distribution Date;

(iii) any Liability the release of which would result in the release of any Person other than a Person released pursuant to Section 10.1(a); provided, however, that

each Party agrees not to bring suit against the other Party or any Subsidiary, Affiliate or Related Person of such other Party with respect to any such Liability; or

(iv) any Liability that any Indemnified Party may have with respect to indemnification or contribution pursuant to this Agreement for claims brought against the Parties or their respective Subsidiaries or Affiliates by third Persons, which Liability shall be governed by the provisions of this Article X and, if applicable, the appropriate provisions of the Ancillary Agreements.

(c) Neither Party shall make, nor permit any of its Subsidiaries or Affiliates to make, any claim or demand, or commence any Action asserting any claim or demand, including any claim of contribution or indemnification, against the other Party, or any other Person released pursuant to Section 10.1(a), with respect to any Liability released pursuant to Section 10.1(a).

(d) If any Subsidiary, Affiliate or Related Person of a Party initiates an Action with respect to claims released by Section 10.1(a), the Party with which such Person is associated shall indemnify the other Party against Expenses or Losses suffered or incurred in connection with such Action in accordance with the provisions set forth in this Article X.

(e) It is the intent of each of the Parties by virtue of the provisions of this Section 10.1 to provide for a full and complete release and discharge of all Liabilities existing or arising from all acts and events occurring or failing to occur or alleged to have occurred or to have failed to occur and all conditions existing or alleged to have existed on or before the Distribution Date, between the Parties (including any Intercompany Agreements), except as expressly set forth in Section 10.1(b). At any time, at the reasonable request of either Party, the other Party shall execute and deliver releases reflecting the provisions hereof in such form as the requesting Party may reasonably request.

Section 10.2 Indemnification by Clearwater. Except as provided in Section 10.5 and except as expressly provided in any Conveyance Instrument or the Employee Matters Agreement, from and after the Distribution, Clearwater shall, and shall cause each of the other members of the Clearwater Group to, indemnify, defend and hold harmless the members of the Potlatch Group, each of their Related Persons and their respective successors and assigns (collectively, the “Potlatch Indemnified Parties”), from and against any and all Expenses or Losses incurred or suffered by one or more of the Potlatch Indemnified Parties, in connection with, relating to, arising out of or due to, directly or indirectly, any of the following items (in each case, regardless of when or where the loss, claim, accident, occurrence, event or happening giving rise to the Expense or Loss took place, or whether any such loss, claim, accident, occurrence, event or happening is known or unknown, or reported or unreported):

(a) the operation of the Pulp-Based Business and Pulp-Based Business Assets;

(b) the Pulp-Based Business Liabilities;

(d) the breach by any member of the Clearwater Group of any covenant or agreement set forth in this Agreement, any Conveyance Instrument or the Employee Matters Agreement;

(e) any claim that the information relating to Clearwater included in the Registration Statement or the Information Statement is or was false or misleading with respect to any material fact or omits or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

Section 10.3 Indemnification by Potlatch. Except as provided in Section 10.5 and except as expressly provided in any Conveyance Instrument or the Employee Matters Agreement, from and after the Distribution, Potlatch shall, and shall cause each of the other members of the Potlatch Group to, indemnify, defend and hold harmless the members of the Clearwater Group, each of their Related Persons and their respective successors and assigns (collectively, the “Clearwater Indemnified Parties”), from and against any and all Expenses or Losses incurred or suffered by one or more of the Clearwater Indemnified Parties in connection with, relating to, arising out of or due to, directly or indirectly, any of the following items (in each case, regardless of when or where the loss, claim, accident, occurrence, event or happening giving rise to the Expense or Loss took place, or whether any such loss, claim, accident, occurrence, event or happening is known or unknown, or reported or unreported):

(a) the operation of the Retained Business and Retained Business Assets;

(b) the Retained Business Liabilities;

(c) the breach by any member of the Potlatch Group of any covenant or agreement set forth in this Agreement, any Conveyance Instrument or the Employee Matters Agreement;

(d) any claim that the information, other than information relating to Clearwater, included in the Registration Statement or the Information Statement is or was false or misleading with respect to any material fact or omits or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

Section 10.4 Applicability of and Limitation on Indemnification. EXCEPT AS EXPRESSLY PROVIDED HEREIN, THE INDEMNITY OBLIGATION UNDER THIS ARTICLE X SHALL APPLY NOTWITHSTANDING ANY INVESTIGATION MADE BY OR ON BEHALF OF ANY INDEMNIFIED PARTY AND SHALL APPLY WITHOUT REGARD TO WHETHER THE LOSS, LIABILITY, CLAIM, DAMAGE, COST OR EXPENSE FOR WHICH INDEMNITY IS CLAIMED HEREUNDER IS BASED ON STRICT LIABILITY, ABSOLUTE LIABILITY, ANY OTHER THEORY OF LIABILITY OR ARISES AS AN OBLIGATION FOR CONTRIBUTION.

Section 10.5 Adjustment of Indemnifiable Losses.

(a) The amount that any Party or any of the members of such Party’s Group (an “Indemnifying Party”) is required to pay to any Person entitled to indemnification hereunder (an “Indemnified Party”) shall be reduced by any insurance proceeds and other amounts actually recovered by or on behalf of such Indemnified Party in reduction of the related Expense or Loss. If an Indemnified Party receives a payment (an “Indemnity Payment”) required by this Agreement from an Indemnifying Party in respect of any Expense or Loss and subsequently actually receives insurance proceeds or other amounts in respect of such Expense or Loss, then such Indemnified Party shall pay to the Indemnifying Party a sum equal to the lesser of (1) the amount of such insurance proceeds or other amounts actually received or (2) the amount of Indemnity Payments actually received previously.

(b) An insurer who would otherwise be obligated to pay any claim shall not be relieved of the responsibility with respect thereto, or, solely by virtue of the indemnification provisions hereof, have any subrogation rights with respect thereto, it being expressly understood and agreed that no insurer or any other third party shall be entitled to a “windfall” (i.e., a benefit he or she would not be entitled to receive in the absence of the indemnification provisions) by virtue of the indemnification provisions hereof.

(c) Indemnity Payments (i) shall not be increased to take into account any tax costs incurred by the Indemnified Party arising from any Indemnity Payments from the Indemnifying Party and (ii) shall not be reduced to take into account any tax benefit received by the Indemnified Party arising from the incurrence or payment of any Indemnity Payment.

Section 10.6 Procedures for Indemnification of Third Party Claims.

(a) If any third Person shall make any claim or commence any Action (collectively, a “Third Party Claim”) against any one or more of the Indemnified Parties with respect to which an Indemnified Party intends to make any claim for indemnification against any member of the Clearwater Group under Section 10.2 or against any member of the Potlatch Group under Section 10.3, such Indemnified Party shall promptly give written notice to the Indemnifying Party describing such Third Party Claim in reasonable detail. Notwithstanding the foregoing, the failure of any Indemnified Party to provide notice in accordance with this Section 10.6(a) shall not relieve the related Indemnifying Party of its obligations under this Article X, except to the extent (and only to the extent) that such Indemnifying Party is actually prejudiced by such failure to provide notice.

(b) Subject to the following provisions of this Section 10.6(b), the Indemnifying Party shall have 30 days after receipt of the notice referred to in Section 10.6(a) to notify the Indemnified Party in writing that it elects to conduct and control the defense of such Third Party Claim, provided that such written notice must contain an express obligation and acknowledgement by the Indemnifying Party that the Indemnified Party will be indemnified and held harmless hereunder with respect to the full amount of all Expenses or Losses the Indemnified Party may suffer arising out of or relating to such Third Party Claim. If the Indemnifying Party does not give the foregoing notice or if the Third Party Claim involves or relates to matters that are described in subsection (i) of the proviso to the immediately following sentence, the Indemnified Party shall have the right to defend, contest, settle or compromise such Third Party Claim in the exercise of its exclusive discretion, subject to the provisions of

Section 10.6(c) and Section 10.6(f), and the Indemnifying Party shall, upon request from the Indemnified Party and to the extent required under this Article X, promptly pay to such Indemnified Party in accordance with the other terms of this Section 10.6(b) the amount of any Expense or Loss resulting from the Indemnified Party’s liability to the third Person claimant. If the Indemnifying Party gives the foregoing notice, the Indemnifying Party shall have the right to undertake, conduct and control, through counsel reasonably acceptable to the Indemnified Party, and at the Indemnifying Party’s sole expense, the conduct and settlement of such Third Party Claim, and the Indemnified Party shall cooperate with the Indemnifying Party in connection therewith; provided, however, that (i) in no event, without the Indemnified Party’s prior written consent (not to be unreasonably withheld or delayed in the event the Indemnifying Party has insurance coverage applicable to such Third Party Claim), will the Indemnifying Party have the right to undertake, conduct and control such Third Party Claim (or the settlement thereof) if such Third Party Claim (A) involves any Action by any Governmental Entity or (B) relates to any environmental Law; and (ii) the Indemnifying Party shall permit the Indemnified Party and counsel chosen by the Indemnified Party and reasonably acceptable to the Indemnifying Party to monitor such conduct or settlement and shall provide the Indemnified Party and such counsel with such information regarding such Third Party Claim as either of them may reasonably request (which request may be general or specific), but the fees and expenses of such counsel chosen by the Indemnified Party shall be borne by the Indemnified Party unless (A) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (B) the named parties to any such Third Party Claim include the Indemnified Party and the Indemnifying Party and in the reasonable opinion of counsel to the Indemnified Party representation of both parties by the same counsel would be inappropriate due to actual or likely conflicts of interest between them, in either of which cases the reasonable fees and disbursements of counsel for such Indemnified Party shall be paid by the Indemnifying Party. Subject to the following sentence, in no event shall the Indemnifying Party settle or compromise any Third Party Claim or consent to the entry of any judgment with respect to a Third Party Claim without the prior written consent of the Indemnified Party, such consent not to be unreasonably withheld or delayed; provided, however, that the Indemnified Party shall not be deemed to have unreasonably withheld consent to any settlement or comprise if such settlement or compromise would (w) result in any lien, encumbrance or other adverse charge to thereafter attach to any asset of any Indemnified Party, (x) result in any injunction against any Indemnified Party, (y) result in or include any acknowledgement, stipulation or statement of a violation of Law by any Indemnified Party, or (z) not include as an unconditional term thereof the giving by the claimant or the plaintiff to the Indemnified Party a complete release from all Liability in respect of such claim. Notwithstanding the foregoing sentence, the Indemnifying Party may settle or compromise a Third Party Claim without the prior written consent of the Indemnified Party if such settlement or compromise (i) involves solely a cash settlement payment that is satisfied and paid entirely by the Indemnifying Party and (ii) includes as an unconditional term thereof the giving by the claimant or the plaintiff to the Indemnified Party a complete release from all Liability in respect of such Third Party Claim.

(c) If the Indemnifying Party shall not have undertaken the conduct and control of the defense of any Third Party Claim as provided above, the Indemnifying Party shall nevertheless be entitled through counsel chosen by the Indemnifying Party and reasonably acceptable to the Indemnified Party to monitor the conduct or settlement of such claim by the Indemnified Party, and the Indemnified Party shall provide the Indemnifying Party and such

counsel with such information regarding such Third Party Claim as either of them may reasonably request (which request may be general or specific), but all costs and expenses incurred in connection with such monitoring shall be borne by the Indemnifying Party.

(d) So long as the Indemnifying Party is contesting any such Third Party Claim in its reasonable good faith judgment, the Indemnified Party shall not pay or settle any such Third Party Claim. Notwithstanding the foregoing, the Indemnified Party shall have the right to pay or settle any such Third Party Claim; provided, however, that in such event the Indemnified Party shall waive any right to indemnity therefor by the Indemnifying Party, and no amount in respect thereof shall be claimed as an Expense or a Loss under this Article X.

(e) If the Indemnified Party determines in its reasonable good faith judgment that the Indemnifying Party is not defending such Third Party Claim in good faith, the Indemnified Party shall have the right to undertake control of the defense of such Third Party Claim upon five days’ written notice to the Indemnifying Party and thereafter to defend, contest, settle or compromise such Third Party Claim in the exercise of its exclusive discretion, subject to Section 10.6(f).

(f) If the Indemnified Party shall have undertaken the conduct and control of the defense of any Third Party Claim as provided above, the Indemnified Party may make settlement (including payment in full) of such Third Party Claim; provided, however, if the Indemnified Party makes such settlement without the written consent of the Indemnifying Party, such settlement shall not be dispositive of whether such Third Party Claim (or any part thereof) is subject to indemnification under this Article X or the extent of the Expense or Loss indemnifiable under this Article X arising from such Third Party Claim (or part thereof).

Section 10.7 Procedures for Indemnification of Direct Claims. Any claim for indemnification by an Indemnified Party against the Indemnifying Party that does not result from a Third Party Claim shall be asserted by written notice from the Indemnified Party to the Indemnifying Party. Such Indemnifying Party shall have a period of 45 days after the receipt of such notice within which to respond thereto. If such Indemnifying Party does not respond within such 45-day period, such Indemnifying Party shall be deemed to have accepted responsibility to provide the indemnity claimed and shall have no further right to contest the validity of such claim. If such Indemnifying Party does respond within such 45-day period and rejects such claim in whole or in part, such Indemnified Party shall be free to pursue resolution as provided in Article XI.

Section 10.8 Contribution. If the indemnification provided for in this Article X is unavailable to an Indemnified Party in respect of any Expense or Loss arising out of or related to information contained in the Registration Statement or the Information Statement, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Expense or Loss in such proportion as is appropriate to reflect the relative fault of the Clearwater Indemnified Parties, on the one hand, or the Potlatch Indemnified Parties, on the other hand, in connection with the statements or omissions that resulted in such Expense or Loss. The relative fault of any Clearwater Indemnified Party, on the one hand, and of any Potlatch Indemnified Party, on the other hand, shall be determined by reference to, among other things, whether the untrue or

alleged untrue statement of a material fact or the omission or alleged omission of a material fact relates to Clearwater, on the one hand, or does not relate to Clearwater, on the other hand.

Section 10.9 Remedies Cumulative. The remedies provided in this Article X shall be cumulative and, subject to the provisions of Article XI, shall not preclude assertion by an Indemnified Party of any other rights or the seeking of any and all other remedies against any Indemnifying Party.

Section 10.10 Survival. All covenants and agreements of the Parties contained in this Agreement relating to indemnification shall survive the Distribution Date indefinitely, unless a specific survival or other applicable period is expressly set forth herein.

ARTICLE XI

DISPUTE RESOLUTION

Section 11.1 Escalation and Mediation.

(a) The Parties agree to use commercially reasonable efforts to resolve expeditiously any dispute, controversy or claim between them with respect to any matter covered hereby that may arise from time to time on a mutually acceptable negotiated basis. In furtherance of the foregoing, any Party involved in such a dispute, controversy or claim may deliver a notice (an “Escalation Notice”) demanding an in-person meeting involving representatives of the Parties at a senior level of management of the Parties (or if the Parties agree, of the appropriate business unit or division within such entity). A copy of any such Escalation Notice shall be given to the General Counsel, or like officer or official, of each Party involved in the dispute, controversy or claim (which copy shall state that it is an Escalation Notice pursuant to this Agreement). Any agenda, location or procedures for such discussions or negotiations between the Parties may be established by the Parties from time to time; provided, however, that the Parties shall use commercially reasonable efforts to meet within 30 days of the Escalation Notice.

(b) The Parties may agree to retain a mediator, acceptable to both Parties, to aid the Parties in their discussions and negotiations by informally providing advice to the Parties. Any opinion expressed by the mediator shall be strictly advisory and shall not be binding on the Parties, nor shall any opinion expressed by the mediator be admissible in any action or proceeding. The mediator shall be selected by the Party that did not deliver the applicable Escalation Notice from the list of individuals to be supplied to the Parties by JAMS/Endispute, the American Arbitration Association or such entity mutually agreeable to the Parties. Costs of the mediator shall be borne equally by the Parties involved in the matter, and each Party shall otherwise be responsible for its own expenses.

Section 11.2 Continuity of Service and Performance. Unless otherwise agreed in writing, the Parties will continue to provide service and honor all other commitments under this Agreement and each Ancillary Agreement during the course of dispute resolution pursuant to the provisions of this Article XI with respect to all matters not subject to such dispute, controversy or claim.

Section 11.3 Choice of Forum. Any mediation hereunder shall take place in Spokane, Washington, unless otherwise agreed in writing by the Parties.

Section 11.4 Ability to Pursue Other Legal Remedies. For the avoidance of doubt, nothing in this Article XI shall prevent any Party from pursuing any and all remedies available to it in connection with a dispute relating to this Agreement or any of the Ancillary Agreements.

ARTICLE XII

ACCESS TO INFORMATION AND SERVICES

Section 12.1 Agreement for Exchange of Information.

(a) At all times from and after the Distribution Date, as soon as reasonably practicable after written request: (i) the Potlatch Group shall at Clearwater’s expense afford to Clearwater, its Subsidiaries and their authorized accountants, counsel and other designated representatives reasonable access during normal business hours to, and provide copies of, all records, books, contracts, instruments, data, documents and other information (collectively, “Information”) in the possession or under the control of the Potlatch Group following the Distribution Date that relates to the Clearwater Group or the Pulp-Based Business; and (ii) the Clearwater Group shall at Potlatch’s expense afford to Potlatch, its Subsidiaries and their authorized accountants, counsel and other designated representatives reasonable access during normal business hours to, and provide copies of, all Information in the possession or under the control of the Clearwater Group following the Distribution Date that relates to the Potlatch Group or the Retained Business; provided, however, that in the event that either Party determines that any such provision of or access to Information could be commercially detrimental, violate any Law or Contract or waive any attorney-client privilege, the Parties shall take all reasonable measures to permit the compliance with such obligations in a manner that avoids any such harm or consequence.

(b) Either Party may request Information under Section 12.1(a) (i) to comply with reporting, disclosure, filing or other requirements imposed on the requesting party (including under applicable securities or tax Laws) by a Governmental Entity having jurisdiction over the requesting party, (ii) for use in any other judicial, regulatory, administrative, tax or other proceeding or in order to satisfy audit, accounting, claims defense, regulatory filings, litigation, tax or other similar requirements, (iii) for use in compensation, benefit or welfare plan administration or other bona fide business purposes or (iv) to comply with its obligations under this Agreement or any Ancillary Agreement.

Section 12.2 Ownership of Information. Any Information owned by one Party that is provided to a requesting Party pursuant to Section 12.1 shall be deemed to remain the property of the providing Party. Unless specifically set forth herein, nothing contained in this Agreement shall be construed to grant or confer rights of license or otherwise in any such Information.

Section 12.3 Compensation for Providing Information. The Party requesting Information agrees to reimburse the providing Party for the reasonable costs, if any, of creating, gathering and copying such Information, to the extent that such costs are incurred for the benefit of the requesting Party.

Section 12.4 Retention of Records. To facilitate the possible exchange of Information pursuant to this Article XII after the Distribution Date, the Parties agree to use commercially reasonable efforts to retain all Information in their respective possession or control on the Distribution Date in accordance with their respective document retention policies as in effect on the Distribution Date. No Party will destroy, or permit any of its Subsidiaries or Affiliates to destroy, any Information that the other Party may have the right to obtain pursuant to this Agreement except in accordance with the first Party’s document retention policy as in effect on the Distribution Date. If either Party proposes to amend its document retention policy in a manner that relates to the Information or the retention thereof (including the period for retention of any Information), such Party shall notify the other Party in writing of such proposed amendment prior to its adoption and take such actions as the other Party may reasonably request with respect to the Information subject to such amendment.

Section 12.5 Limitation of Liability. No Party shall have any liability to the other Party (i) if any Information exchanged or provided pursuant to this Agreement that is an estimate or forecast, or that is based on an estimate or forecast, is found to be inaccurate, in the absence of gross negligence or willful misconduct by the Party providing such Information, or (ii) if any Information is destroyed after commercially reasonable efforts to comply with the provisions of Section 12.4.

Section 12.6 Production of Witnesses. At all times from and after the Distribution Date, each Party shall use commercially reasonable efforts to make available to the other Party (without cost (other than reimbursement of actual out-of-pocket expenses) to, and upon prior written request of, the other Party) its directors, officers, employees and agents as witnesses to the extent that the same may reasonably be required by the other Party in connection with any Action in which the requesting Party may from time to time be involved with respect to the Pulp-Based Business, the Retained Business or any transactions contemplated hereby.

Section 12.7 Confidentiality.

(a) From and after the Distribution Date, each of the Potlatch Group and the Clearwater Group shall hold, and shall cause their respective directors, officers, employees, agents, consultants, advisors and other representatives to hold, in strict confidence, with at least the same degree of care that applies to the Potlatch Group’s confidential and proprietary information pursuant to policies in effect as of the Distribution Date or such other procedures as may reasonably be adopted by the applicable Party after the Distribution Date, all non-public information concerning or belonging to the other Party or any of its Subsidiaries or Affiliates obtained by it prior to the Distribution Date, accessed by it pursuant to Section 12.1, or furnished to it by the other Party or any of its Subsidiaries or Affiliates pursuant to this Agreement, any Conveyance Instrument or the Employee Matters Agreement, and shall not release or disclose such information to any other Person, except their representatives, who shall be bound by the provisions of this Section 12.7; provided, however, that the Potlatch Group and the Clearwater Group and their respective directors, officers, employees, agents, consultants, advisors and other representatives may disclose such information if, and only to the extent that, (i) a disclosure of such information is compelled by judicial or administrative process or, in the opinion of such Party’s counsel, by other requirements of Law (in which case the disclosing Party will provide, to the extent practicable under the circumstances, advance written notice to the other Party of its

intent to make such disclosure), or (ii) such Party can show that such information (A) is published or is or otherwise becomes available to the general public as part of the public domain without breach of this Agreement; (B) has been furnished or made known to the recipient without any obligation to keep it confidential by a third party under circumstances which are not known to the recipient to involve a breach of the third party’s obligations to a Party hereto; or (C) was developed independently of information furnished to the recipient under this Agreement.

(b) Each Party acknowledges that the other Party would not have an adequate remedy at Law for the breach by the acknowledging Party of any one or more of the covenants contained in this Section 12.7 and agrees that, in the event of such breach, the other Party may, in addition to the other remedies that may be available to it, apply to a court for an injunction to prevent breaches of this Section 12.7 and to enforce specifically the terms and provisions of this Section 12.7. Notwithstanding any other section hereof, the provisions of this Section 12.7 shall survive the Distribution Date indefinitely.

Section 12.8 Privileged Matters.

(a) Each of the Potlatch Group and the Clearwater Group agrees to maintain, preserve and assert all privileges, including, without limitation, privileges arising under or relating to the attorney-client relationship (which shall include the attorney-client and work product privileges), not heretofore waived, that relate to the Pulp-Based Business, the Pulp-Based Business Liabilities, the Retained Business or the Retained Business Liabilities for any period prior to the Distribution Date (“Privilege”). Each Party agrees that it shall not waive any Privilege that could be asserted under applicable Law without the prior written consent of the other Party. The rights and obligations created by this Section 12.8 shall apply to all information relating to the Pulp-Based Business, the Pulp-Based Business Liabilities, the Retained Business or the Retained Business Liabilities as to which, but for the Distribution, either Party would have been entitled to assert or did assert the protection of a Privilege (“Privileged Information”), including (i) any and all information generated prior to the Distribution Date but which, after the Distribution, is in the possession of either Party; and (ii) all information generated, received or arising after the Distribution Date that refers to or relates to Privileged Information generated, received or arising prior to the Distribution Date.

(b) Upon receipt by either Party of any subpoena, discovery or other request that may call for the production or disclosure of Privileged Information or if either Party obtains knowledge that any current or former employee of a member of the Potlatch Group or the Clearwater Group has received any subpoena, discovery or other request that may call for the production or disclosure of Privileged Information, such Party shall notify promptly the other Party of the existence of the request and shall provide the other Party a reasonable opportunity to review the information and to assert any rights it may have under this Section 12.8 or otherwise to prevent the production or disclosure of Privileged Information. Each Party agrees that it will not produce or disclose any information that may be covered by a Privilege under this Section 12.8 unless (i) the other Party has provided its written consent to such production or disclosure (which consent shall not be unreasonably withheld), or (ii) a court of competent jurisdiction has entered a final, nonappealable order finding that the information is not entitled to protection under any applicable Privilege. Any costs associated with asserting any Privilege shall be borne by the Party requesting that such Privilege be asserted.

(c) Each Party’s transfer of books and records and other information to the other Party, and each Party’s agreement to permit the other Party to possess Privileged Information existing or generated prior to the Distribution Date, are made in reliance on each Party’s agreement, as set forth in Section 12.7 and Section 12.8, to maintain the confidentiality of Privileged Information and to assert and maintain all applicable Privileges. The access to information being granted pursuant to Section 12.1, the agreement to provide witnesses and individuals pursuant to Section 12.6 and the transfer of Privileged Information pursuant to this Agreement shall not be deemed a waiver of any Privilege that has been or may be asserted under this Section 12.8 or otherwise. Nothing in this Agreement shall operate to reduce, minimize or condition the rights granted to each Party in, or the obligations imposed upon each Party by, this Section 12.8.

ARTICLE XIII

MISCELLANEOUS

Section 13.1 Entire Agreement. This Agreement, the Ancillary Agreements, and the documents delivered pursuant hereto and thereto, constitute the entire agreement between the Parties with respect to the subject matter contained herein or therein, and supersede all prior agreements, negotiations, discussions, understandings, writings and commitments between the Parties with respect to such subject matter.

Section 13.2 Choice of Law. This Agreement shall be governed by and construed and enforced in accordance with the substantive laws of the State of Delaware and the federal laws of the United States of America applicable therein, as though all acts and omissions related hereto occurred in Delaware.

Section 13.3 Amendment. This Agreement shall not be amended, modified or supplemented except by a written instrument signed by an authorized representative of each of the Parties.

Section 13.4 Waiver. Any term or provision of this Agreement may be waived, or the time for its performance may be extended, by the Party or Parties entitled to the benefit thereof. Any such waiver shall be validly and sufficiently given for the purposes of this Agreement if, as to any Party, it is in writing signed by an authorized representative of such Party. The failure of any Party to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, or in any way to affect the validity of this Agreement or any part hereof or the right of any Party thereafter to enforce each and every such provision. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach.

Section 13.5 Partial Invalidity. Wherever possible, each provision hereof shall be interpreted in such a manner as to be effective and valid under applicable Law, but in case any one or more of the provisions contained herein shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such provision or provisions shall be ineffective to the extent, but only to the extent, of such invalidity, illegality or unenforceability without invalidating the remainder of such provision or provisions or any other provisions hereof, unless such a construction would be unreasonable.

Section 13.6 Execution in Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original instrument, but all of which shall be considered one and the same agreement, and shall become binding when one or more counterparts have been signed by and delivered to each of the Parties.

Section 13.7 Successors and Assigns. This Agreement and each Ancillary Agreement shall be binding upon and inure to the benefit of the Parties hereto and thereto, respectively, and their successors and permitted assigns; provided, however, that the rights and obligations of either Party under this Agreement and each Ancillary Agreement shall not be assignable by such Party without the prior written consent of the other Party. The successors and permitted assigns hereunder shall include, without limitation, any permitted assignee as well as the successors in interest to such permitted assignee (whether by merger, liquidation (including successive mergers or liquidations) or otherwise).

Section 13.8 Third Party Beneficiaries. Except to the extent otherwise provided in Article X or in any Ancillary Agreement, the provisions of this Agreement and each Ancillary Agreement are solely for the benefit of the Parties and their respective Affiliates, successors and permitted assigns and shall not confer upon any third Person any remedy, claim, liability, reimbursement or other right in excess of those existing without reference to this Agreement or any Ancillary Agreement.

Section 13.9 Notices. All notices, requests, claims, demands and other communications required or permitted hereunder shall be in writing and shall be deemed given or delivered (i) when delivered personally, (ii) if transmitted by facsimile when confirmation of transmission is received, (iii) if sent by registered or certified mail, postage prepaid, return receipt requested, on the third business day after mailing or (iv) if sent by private courier when received; and shall be addressed as follows:

Section 13.11 Force Majeure. No Party shall be deemed in default of this Agreement to the extent that any delay or failure in the performance of its obligations under this Agreement results from any cause beyond its reasonable control and without its fault or negligence, including, without limitation, acts of God, acts of civil or military authority, embargoes, epidemics, war, riots, insurrections, fires, explosions, earthquakes, floods, unusually severe weather conditions, labor strikes or work stoppages as a result of labor unrest, unavailability of parts, or, in the case of computer systems, any failure in electrical or air conditioning equipment. In the event of any such excused delay, the time for performance shall be extended for a period equal to the time lost by reason of the delay.

Section 13.12 No Public Announcement. Neither Potlatch nor Clearwater shall, without the approval of the other, make any press release or other public announcement concerning the transactions contemplated by this Agreement, except as and to the extent that any such Party shall be so obligated by Law or the rules of any stock exchange or quotation system, in which case the other Party shall be advised and the Parties shall use commercially reasonable efforts to cause a mutually agreeable release or announcement to be issued; provided, however, that the foregoing shall not preclude communications or disclosures necessary to implement the provisions of this Agreement or any Ancillary Agreement or to comply with the accounting and SEC disclosure obligations or the rules of any stock exchange.

Section 13.13 Termination. Notwithstanding any provisions hereof, this Agreement may be terminated and the Distribution abandoned at any time prior to the Distribution Date by and in the sole discretion of the Board of Directors of Potlatch without the prior approval of any Person.
