 RETAINED OBLIGATION AGREEMENT 
 THIS RETAINED OBLIGATION AGREEMENT (this “Agreement”) is entered into as of
                            , by and between CLEARWATER PAPER CORPORATION, a Delaware
corporation formerly known as Potlatch Forest Products Corporation (“Clearwater”), and POTLATCH CORPORATION, a Delaware corporation (“Potlatch”), and shall be effective as of the Effective Time
(as defined in Section 6.09). 
 RECITALS 
 WHEREAS, on December 4, 1989 the predecessor of Potlatch Forest Holdings, Inc., a Delaware corporation and wholly-owned subsidiary of Potlatch (“PFHI”), issued $100,000,000 9-1/8% Credit
Sensitive Debentures due 2009 (the “Debentures”) pursuant to an Indenture dated as of April 1, 1986 (as supplemented by the First Supplemental Indenture dated as of February 3, 2006, the
“Indenture”) between PFHI and U.S. Bank National Association as successor trustee under the Indenture (“Indenture Trustee”); and 
 WHEREAS, on October 10, 2005, Potlatch incorporated Clearwater as a wholly-owned subsidiary in connection with a series of transactions the result
of which was, on January 1, 2006, to convert Potlatch into a Real Estate Investment Trust (as defined in Sections 856-860 of the Internal Revenue Code of 1986, as amended) and to transfer to Clearwater all of its manufacturing facilities that
produce bleached pulp products, including paperboard and tissue products, and wood products, Potlatch’s harvest and log sales and real estate sales and development businesses; and 
 WHEREAS, in connection with the aforementioned conversion of Potlatch into a Real Estate Investment Trust and transfer to Clearwater of the
aforementioned assets, Section 3.1(a) of the Contribution and Assumption Agreement, dated December 30, 2005 (the “Contribution Agreement”), between Potlatch and Clearwater, provided, “In consideration of the
contribution by Potlatch to . . . [Clearwater] as set forth in Section 2.1, . . . [Clearwater] agrees with Potlatch to assume and duly and punctually to make all payments of principal (and premium, if any) and interest on the Potlatch
Indebtedness in accordance with the terms thereof, and each of Potlatch and . . . [Clearwater] expects that . . . [Clearwater] shall make the entirety of each such payment (it being understood that the provisions of this Section 3.1 are not
intended to, and do not, affect the contractual relationship between Potlatch and the holders of the Potlatch Indebtedness)”; and 
 WHEREAS, the “Potlatch Indebtedness” assumed by Clearwater as described in the preceding recital included PFHI’s obligations under the Debentures; and 
 WHEREAS, following the execution and delivery of this Agreement, Potlatch will distribute to its stockholders all outstanding shares of common stock of
Clearwater; and 
 WHEREAS, while Potlatch and Clearwater expect Clearwater to be able to satisfy its obligations under the Contribution
Agreement with respect to the Debentures as interest and principal payments on the Debentures become due and payable, the parties desire by this Agreement to memorialize their understanding of their rights and obligations in the unlikely 

  

 1 








 
event that events in the credit markets may preclude Clearwater from obtaining funds to refinance the Debentures on commercial terms; and 
 WHEREAS, the parties desire to confirm their respective rights and obligations with respect to Section 3.1(a) of the Contribution Agreement with
respect to the Debentures (capitalized terms used herein have the respective meanings given them in Section 6.09) and to enter into other agreements as set forth herein: 
 NOW, THEREFORE, for valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows:

 ARTICLE I 
 RETAINED
OBLIGATION 
 Section 1.01. Retained Obligation. 
 (a) Clearwater hereby (i) confirms and restates, solely with respect to the Debentures, its obligation in Section 3.1(a) of the
Contribution Agreement, which provides, “In consideration of the contribution by Potlatch to . . . [Clearwater] as set forth in Section 2.1, . . . [Clearwater] agrees with Potlatch to assume and duly and punctually to make all payments of
principal (and premium, if any) and interest on the Potlatch Indebtedness in accordance with the terms thereof, and each of Potlatch and . . . [Clearwater] expects that . . . [Clearwater] shall make the entirety of each such payment (it being
understood that the provisions of this Section 3.1 are not intended to, and do not, affect the contractual relationship between Potlatch and the holders of the Potlatch Indebtedness)” and (ii) acknowledges that the Debentures are
included in the “Potlatch Indebtedness” referred to in such Section 3.1(a). For the avoidance of doubt, Clearwater’s obligations under this Agreement shall not include any obligations or liabilities that constituted
“Potlatch Indebtedness” under the Contribution Agreement other than those of PFHI under the Debentures, but shall include the obligation to make accelerated payments of amounts due with respect to the Debentures to the extent such
accelerated payments are required for any reason under the Indenture. 
 (b) Clearwater’s obligation under
Section 1.01(a) to pay interest under the Debentures shall include any additional interest that may become due and payable thereunder after the date of this Agreement as a result of any change in the debt rating, after the date of this
Agreement, on the Debentures by S&P or Moody’s as provided in the Debentures. 
 Section 1.02. No Amendments to Debentures.
Without Clearwater’s prior written consent, Potlatch shall not, and shall cause PFHI not to, amend or agree to amend any term or condition of the Debentures. 
 Section 1.03. Clearwater to Seek Refinancing. Clearwater shall use commercially reasonable efforts to issue, as soon as reasonably practical, debt or equity securities or borrow money from one or more financial
institutions or other lenders, in each case, on terms and 
  

 2 








 
conditions reasonably acceptable to Clearwater, in an aggregate amount sufficient to satisfy and discharge the Indenture with respect to the Debentures as
described in Section 1.04. Notwithstanding the foregoing, Clearwater shall not be required to borrow moneys under the Loan and Security Agreement dated [            ], 2008 (as
the same may be amended, amended and restated or replaced from time to time, the “Revolving Loan Agreement”) among Clearwater, the financial institutions party thereto as lenders, and Bank of America, N.A., as agent, to
satisfy the obligation set forth in the preceding sentence. Clearwater shall, from time to time, upon request by Potlatch, advise Potlatch of its efforts to issue the securities or to borrow the moneys described in this Section 1.03.

 Section 1.04. Satisfaction and Discharge of Debentures. 
 (a) Concurrently with its receipt of Net Cash Proceeds from any Equity Issuance, Debt Incurrence or Disposition on or before
December 1, 2009, where the amount of such Net Cash Proceeds is sufficient to satisfy and discharge the Indenture with respect to the Debentures pursuant to Section 401(1)(B)(iii) of the Indenture, Clearwater shall deposit in trust with
the Indenture Trustee the money or U.S. Government Obligations (or a combination thereof) necessary to so satisfy and discharge the Indenture with respect to the Debentures (the sufficiency of such deposit amount to be confirmed by a nationally
recognized firm of independent certified public accountants designated by Potlatch), provided, however, that Clearwater may reduce in whole or in part the amount required to be so deposited by concurrently delivering to the Indenture Trustee on
behalf of PFHI for cancellation pursuant to Sections 309 and 401(1)(A) of the Indenture, Debentures acquired by Clearwater. 
 (b) At any time before December 1, 2009 Clearwater may deposit in trust with the Indenture Trustee money or U.S. Government Obligations (or a combination thereof) necessary to so satisfy and discharge the Indenture with respect to the
Debentures (the sufficiency of such deposit amount to be confirmed by a nationally recognized firm of independent certified public accountants designated by Potlatch), provided, however, that Clearwater may reduce in whole or in part such amount by
concurrently delivering to the Indenture Trustee on behalf of PFHI for cancellation pursuant to Sections 309 and 401(1)(A) of the Indenture, Debentures acquired by Clearwater. 
 Section 1.05. Satisfaction of Indenture Obligations. In connection with the actions taken by Clearwater pursuant to Section 1.01(a) or 1.04
or otherwise to satisfy and discharge the Indenture with respect to the Debentures, Clearwater shall, at its cost and expense, cooperate with PFHI in connection with PFHI’s preparation, execution and delivery of the “Company Request”,
the “Officers’ Certificate” and the “Opinion of Counsel” (each, as defined in the Indenture) which are required to be delivered by PFHI to the Indenture Trustee pursuant to Section 401 of the Indenture in order to
satisfy and discharge the Indenture with respect to the Debentures.

 Section 1.06. Escrow Account. 
 (a) If Clearwater shall arrange for any Equity Issuance, Debt Incurrence or Disposition before December 1, 2009 and such Net Cash
Proceeds are expected or should reasonably be expected to be insufficient to satisfy and discharge the Indenture with respect to the Debentures as contemplated by Section 1.04, then: 
 (i) Clearwater shall notify Potlatch no less than 10 Business Days before the consummation of such Equity Issuance, Debt Incurrence or
Disposition that Clearwater expects to complete such transaction but does not expect that the Net Cash Proceeds therefrom will be sufficient to satisfy and discharge the Indenture as contemplated in Section 1.04; and 
 (ii) As soon as reasonably practicable, but in no event later than two Business Days before the date on which such Equity Issuance, Debt
Incurrence or Disposition shall be consummated, Clearwater shall enter into an escrow agreement (the “Escrow Agreement”) with a bank (the “Escrow Agent”) designated by Potlatch and reasonably
acceptable to Clearwater, that shall provide that (A) Clearwater and Potlatch shall appoint such bank as their escrow agent for purposes of such escrow agreement, (B) Clearwater shall establish an escrow account (the “Escrow
Account”) with such bank solely for the purpose of holding the Net Cash Proceeds from such Equity Issuance, Debt Incurrence or Disposition as provided in the escrow agreement, (C) Potlatch shall have a first priority security
interest in the Escrow Account and the funds therein (and in connection therewith, the Escrow Agent shall agree in the Escrow Agreement that Potlatch shall have “control” over the Escrow Account for purposes of perfecting such security
interest), (D) the Escrow Agent will enter into a control agreement that will perfect Potlatch’s security interest in the Escrow Account and the funds therein, in form and substance reasonably satisfactory to Potlatch, (E) Clearwater
will deposit the entire Net Cash Proceeds of such Equity Issuance, Debt Incurrence or Disposition into the Escrow Account, (F) the Escrow Agent will invest the funds deposited in the escrow account as directed by Clearwater, subject to
investment guidelines previously agreed with Potlatch, (G) all Net Cash Proceeds and the earnings thereon will be disbursed to the Indenture Trustee on December 1, 2009 towards satisfaction and discharge of the Indenture with respect to
the Debentures pursuant to Section 401(1)(B)(i) of the Indenture, (H) Clearwater shall pay all fees, expenses and other charges of the Escrow Agent, (I) all funds and earnings on the funds in the Escrow Account shall be the property
of Clearwater, subject to the security interest in favor of Potlatch, and (J) Clearwater shall indemnify the Escrow Agent for all matters for which indemnification is agreed under such Escrow Agreement. 
 (b) Concurrently with its receipt of Net Cash Proceeds from any Equity Issuance, Debt Incurrence or Disposition before December 1,
2009 as described in Section 1.06(a), Clearwater shall: 
 (i) deposit the same in the Escrow Account; and 

 

 4 








 (ii) notify Potlatch that such deposit has been made and the amount thereof. 

(c) If the Escrow Account is established pursuant to this Section 1.06, Clearwater shall timely deliver to the Escrow Agent all
necessary wire transfer instructions and account information the Escrow Agent shall require for it to ensure that the Indenture Trustee will receive and accept the funds transferred from the Escrow Account to the Indenture Trustee on
December 1, 2009.

deem appropriate, but in any event on or after the date a Note is required to have been issued by Clearwater pursuant to Section 2.03; provided, however, that Lender shall not record and perfect the Mortgage with respect to a Note issued

failure to pay interest under the Debentures when the same is due and payable thereunder and Lender does not make a loan to Clearwater pursuant to Section 2.02, Clearwater shall not be deemed to be in breach of its obligations under
Section 1.01 unless and until Clearwater does not pay the interest on the Debentures when the same would have become due and payable on June 1, 2009 absent such Acceleration Event or Clearwater does not pay the interest or principal on the
Debentures when the same would have become due and payable on December 1, 2009 absent such Acceleration Event. Clearwater and Potlatch agree that where money damages would be an inadequate remedy for a breach, and they agree that money damages
would not be an adequate remedy for a breach of Section 4.05, Potlatch shall be entitled to specific performance. 
 Section 5.04.
Default Rate. Clearwater shall pay Lender interest on any amount of principal or interest not paid when due under the Note issued pursuant to Section 2.03(b) at the rate at which interest shall then accrue thereunder plus two percent
